The Great Depression - 1698 Words

The 1930s was one of the most challenging times in US history, where the Great Depression caused millions of Americans to suffer through hardships because of the economy. Many people were out of work and unemployed, and the government at the time, believed that the best option was to stay out of its affairs, leaving the struggling people hung out to dry. It was not until Franklin Roosevelt was elected president, that the state of the country began to change. And that was due to the creation of the New Deal; a plan to alleviate the state of the country, providing help through increased government spending and programs, that led to its eventual recovery after the second World War. Many have argued that the New Deal was unconstitutional and violated the rights of government power. Roosevelt responded to these arguments speaking of political and economic inequality claiming that â€Å"these economic royalists complain that we seek to overthrow the institutions of America. What they are really complain of is that we seek to take away their power. Our allegiance to American institutions requires the overthrow of this kind of of power† (Voices of Freedom, 169).

About David Adjaye, African-Born World Architect

About David Adjaye, African-Born World Architect With an exterior siding of bronzed aluminum panels and an entry hall with more wood than the hold of a slave ship, the National Museum of African American History and Culture in Washington, DC may become David Adjayes most recognizable work. The Tanzania-born British architect creates transformative designs, from this national museum for the US to an old rail station that is now the Nobel Peace Center in Oslo, Norway.

Furniture and Product Designs: David Adjaye has a collection of side chairs, coffee tables, and textile patterns offered by Knoll Home Designs.   He also has a line of circular chairs on stainless steel tubular frames called Double Zero for Moroso. About David Adjaye: Because Davids father was a government diplomat, the Adjaye family moved from Africa to the Middle East and finally settled in England when David was a young teenager. As a graduate student in London, the young Adjaye traveled from traditional Western architectural havens, like Italy and Greece, to spending time in Japan learning about modern Eastern architecture. His world experience, including returning to Africa as an adult, informs his designs- not known for a particular style, but for a thoughtful representation embedded into individual projects. Another experience that has affected the work of David Adjaye is the disabling illness of his brother, Emmanuel. At a young age, the future architect was exposed to the dysfunctional designs of public institutions used by his family as they cared for a newly paralyzed child. He has said many times that functional design is even more important than beauty. In December 2015, Adjaye Associates was asked to submit a proposal for the Obama Presidential Center, to be built in Chicago.

Atomic Spectra Lab Report Example | Topics and Well Written Essays - 250 words

Atomic Spectra - Lab Report Example Each element have different energy level orbital, due to which, electron movement from one orbital to another is different for each element. As the wavelength of emitted radiations depends on the difference between the energy level of these orbital and so the line spectra, that’s why different elements have different line spectra. Yes, the element will emit the same line spectrum if a different excitation source is used. The energy orbital (in which the electron revolve) are fixed in an element. The electron at lower energy orbit will take some specific amount of energy (irrespective of, it is coming from electricity or flame) and go to some higher orbit. And on return will emit the same energy in the form of photon of particular wavelength. When the light is passed through an element, the element absorbs certain wavelengths while the rest of the wavelength pass through it. This spectrum is called absorption spectrum. The absorb wavelength appear as bright while the background is bright. No, there is no ambiguity in determining the identity of the unknown as there are very less chance (negligible) that spectral lines of any two compounds match. The contamination of dust particles over the unknown is the most problematic error that can occur. Octadecene is a hazard chemical.

At the time beginning of this business the owner of the company started the business operation in US and after that it got success in that particular market. Gradually they become a strong player and increase their sales revenue from this market. Strong presence also helps the company to establish a stable customer base in this market. The company can generate almost 83% of its total revenue from one customer. The company is involved to produce major components for this customer. It can be said that that customer has started to depend on the component o this company which is one of the biggest strength of this business (Akanda, 2013).

Classical Realism Essay Example | Topics and Well Written Essays - 1500 words - 1

Classical Realism - Essay Example Classical realism may seem a realistic approach in international relations however; to implement the same may not be entirely possible. The changing dynamics of world politics, globalization may not allow nations to continue to dominate for longer period of time. Further, the influence of such forces may not allow complete independence to the States to design and execute their international relations strategies in the light of their own self-interest. Classical Realism is rooted in the belief that since desire for power is one of the characteristics of the flawed human nature therefore States also attempt to increase their capabilities to gain more power. As such for classical realists, the international politics is bad or evil because people making the foreign policies are often bad too. The very concept of classical realism therefore suggests that the self-interests of the nations are basically above any other moral obligations of any State. Classical realism also outlines the need for nation-states and indicates that they are motivated by the national interests. These national interests however, are disguised in the overall moral obligations of the States. Classical realists argue that at the international level, States are the major actors deciding on their own based upon overall costs and benefits. It is however, critical to understand that there is an inherent dichotomy within classical realism. Iadvocates that the domestic politics as well as affairs should be dealt in accordance.

In order to provide privacy, a region surrounding the accurate location will be uploaded to the system. 4.5Â  MODULE STRUCTURE The below is the structure of modules: Username/password User’s Credentials User Data User Data Query for Processed data Friends Send FeedbackFriend ListFriend List Figure 4.2 : The Module design 4.4.1 DESCRIPTION OF MODULES This section describes each of the above modules in brief. Module: LoginOrRegister This module contains login or registration in order to register the user with Friendbook application. If the user has already registered, then he/she can directly login and start using the application. If he/she is not registered then he/she has to register with friendbook application. Module: Authenticate Users This module compares the entered Username and Password with the respective records among the database entries. If a match is found, then redirects the user to his/her profile page. Else, an appropriate message is thrown and the user is redirected to the registration page. For registration, compares the Username entered with the ones in the database to check its availability. If unavailable, then asks for a different Username, else create a new record in the database and save the entered details. Redirects the user to his/her profile page on registration with appropriate message, if the Username is not already present. If the Username entered during registration is not unique, then an appropriate message is thrown. Name and Usernames should start with an alphabet and Password should contain at least one alphabet and one numeric character and one special character. Module: Collect_Data_From_Sensors Smartphone (e.g., iPhone or Android-based smartphones) are equipped with a rich set of embedded sensors, such as GPS, accelerometer, microphone, gyroscope, and camera. On the client side, each smartphone records data of its user from the sensors such as accelerometer, and GPS information. This collected data is further sent to the server for further processing. Module: Data Collection and Pre-processing This module collects the data sent from the client side. The raw data collected will be in format {time ,latitude ,longitude ,accx ,accy ,accz }. The collected raw data is further pre processed to remove outliers. Median filtering technique is used for outlier detection and removal. An unsupervised learning technique is applied on the preprocessed data to form clusters known as Kmeans clustering algorithm. The resulting clusters forms a list of activities carried out by a user, where each cluster representing an activity. Module: Activity Recognition Now that the k clusters are formed, each represents an activity, lifestyles are further extracted from these activities using LDA algorithm. A library called LAML is used*. It provides a convenient API to get topic structures for an array of input strings.The extracted lifestyles are used to find the similarities between the users. Once the similarity is calculated, the user who has highest similarity is suggested as a friend. Module: User Query and Feedback Control This module performs two tasks, it accepts and responds to user queries (eg, query for friend list) and collects feedback from users in order to improve the accuracy of the friend recommendation system. 4.6Â  INTERFACE DESCRIPTION: The following is the list of external interfaces: SOCIAL NETWORK PORTAL: A portal where the users can do registration by entering their details and also provide a feedback on the recommendations to improve the accuracy of the system. It is implemented using JSP and HTML. MOBILE INTERFACE: It continually sends the daily activities to the server via network using TCP connection. The daily activities are characterized by walking, sitting and GPS location. RECOMMENDATION SYSTEM : This is the interface in which the friend recommender algorithm works in the background. This interface will be used by the users. Customer cannot do many operations, but their feedbacks or ratings are very important to create a relevant recommendation. End users can only provide feedback and view recommendations. HARDWARE INTERFACES : The recommendation system can work on any smartphone device. These devices should have some limit requirements to make the application run effectively. The processor speed and internet speed are expected to be high. SOFTWARE INTERFACES: This system can work on any platform. Internet connection is a must to reach the system. Moreover, most of the application will be coded by Java. Java APIs of database management tools such as Netbeans, which is a standalone workbench application to interact with database management tools. 4.6.1 Use Case Diagrams And Key Features A use case diagram is a kind of behavioral design, which is constructed from an analysis. It presents a graphical synopsis of the capabilities provided by a system in terms of actors, aims and dependencies between use cases. Friend book user can perform following activities: Install the application in their mobiles Login/Register with the application View the list of most similar friends Upload feedback for improving accuracy of the system. The Use Case diagram in Figure 4.3, shows the different functionalities a friendbook user can perform. Figure 4.3 : Friendbook User Use Case The System can perform following activities: Collect raw data from users Pre-process the data Perform Activity Recognition and extract the lifestyles using LDA Find the list of friends based on similarity between users Handle Feedback Figure 4.4 : The Server Part Use Case 4.8Â  Class Diagram Top Level Client-Side Class Diagram: The client side class diagram, mainly consists of UI(user interface) required for a user to register with the application by providing user’s information, after which user will be able to login and start the service. Once the application starts, it continually records the values from sensors in the format: The above values are to the server at regular intervals (say 3secs). In order to send the values to server a TCP connection is setup. Once the connection is setup, the device will start sending the data. The users can also provide a feedback on the recommendation results given to them. Top Level Server-Side Class Diagram: The server-side class diagram, consists of classes that are executed in a sequential manner. Firstly, ActivityClustering class collects the data sent from the android device, and pre-processes it using median filtering technique. After the data is filtered, the processed data is then partitioned into k clusters using k-means algorithm. Next, a class known as ConvertToActivitySeq is invoked, which maps the activities to cluster they are close to and produces a list containing sequence of activities i.e,. the life document. This document is further given as an input to LifeStylemodelling class, which computes p(word/document) i.e, it calculates probability of word given the document matrix. This matrix is then decomposed to produce two matrices, called p(word/lifestyle) and p(lifestyle/document). Finally, p(lifestyle/document) matrix is used to calculate the similarities of the lifestyles between users. 4.8Â  DATA FLOW DIAGRAM The data flow diagrams are pictorial representation of data flowing in the system. DFD’s are used for the purpose of viewing the data processing in the system. In a data flow diagram, the data elements flow from external or an internal data source, through an internal process. Level 0 Data Flow Diagram A level 0 DFD or a context level design represents the intercommunication between the system and external sources, which act as data sinks. In Level 0 DFD, the interaction between the system and external entity are designed in terms of data flows across the system boundaries. This level diagram shows the complete system as a single procedure. In the DFD diagram shown in Fig*, the lifestyle information are the sensor values sent from the client i.e., android phone to the server. The data sent from client are processed to produce a list of potential friends. Figure 4.* : Level 0 DFD of Lifestyle based friend recommender Level 1 Data Flow Diagram The level 1 DFD, exhibits how the system is split into sub components, where each component represents one or more data flows to or from an external source. And when combined, it provides the complete functionality of the system as a whole. It represents the inter components data flows in a specific sequence and also the data flow between the components of the system. The proposed application consists of the components as shown in the figure 5.*. It first performs data collection, raw data pre-processing by noise removal, Activity recognition where each cluster represents an activity and finally calculates similaties between users to suggest a friend. Figure 5.* : Level 1 DFD of Lifestyle based friend recommender 4.9Â  OBJECTS AND ACTIONS (SEQUENCE DIAGRAM) The sequence diagrams shows below. Sequence for Setup Connection: This sequence is to set up FOR TCP connection between user and the server. Also monitors GPS and Accelerometer by collecting the data from them. Sequence for Monitor Result to the server: The raw data, that is sent from the client is collected by server. And the collected raw data is pre-processed for outlier removal. Sequence for Finding Friends: When the user queries for the friend list, the server accepts the request from the client and responds by sending the potential list of friends. Sequence for Data Collection: The data collection module collects life documents from users’ smartphones. The life document is collection of users activities. The life styles of users are extracted by the life style analysis module with the probabilistic topic model(by using a library for LDA ). Then the life style indexing module puts the life styles of users into the database in the format of (life- style, user) instead of (user, life-style). As the packet arrives , these packet will be store in files. Sequence for Preprocessing: The user sends data, and preprocesses to make the data consistent, by remove irrelevant data.The preprocessed data is converted into archive and upload to the database. Sequence for Database Connection: Data base connection is established when a friend request query is posed. A TCP connection will be established between user and server. Server will process this request and respond with the extracted information from the database i.e, the list of potential friends. 4.10Â  PSEUDO CODE MOBILE END: SERVER SIDE PSEUDO CODE:

Aristotle vs Plato Essay -- Metaphysics,The Four Causes, Soul and Body

Aristotle is considered by many to be one of the most influential philosophers in history. As a student of Plato, he built on his mentor’s metaphysical teachings of things like The Theory of Forms and his views on the soul. However, he also challenged them, introducing his own metaphysical ideas such as act and potency, hylemorphism, and the four causes. He used these ideas to explain his account of the soul and the immateriality of intellect. Prior to Aristotle, philosophers like Parmenides and Heraclitus argued about the existence of change. Aristotle used the terms act and potency to respond to Parmenides arguments about change’s non-existence and bridge the gap between Parmenides and Heraclitus’ polar views. Aristotle used act and potency to examine numerous things such as, motion, causality and metaphysics. He explained that the act or actuality of a thing is its truest way of being and that potency or potential is a things capability of being, further than its current existence. For example, a soccer ball is in actuality on the field; but in potentiality it can be kicked and enter the goal. According to Aristotle’s reasoning, the becoming or change of the soccer ball occurs when a potential is actualized. Though these changes occur, the thing itself stays the same. When the ball is kicked, it loses the actuality of being on the field and gains the actuality of being in the goal; in turn, the bal l then loses the potentiality of being in the goal and gains the potentiality of being on the field. Aristotle later explains that the â€Å"full reality† of a thing is when the actuality and potentiality of a thing are combined. He notes that while things can be â€Å"pure potency,† meaning not actual or real, that there is... ...usible argument. I can see the understanding in both schools of thought. If I were to think logically I would say Aristotle, because he based his conclusions on science and evidence. However, it is their views on the soul where I make my decision on who I (If I had to choose) agree with. I personally believe that the soul, my soul, is something that exists separate from my body. I believe that my body is a temporary and imperfect thing, but that my soul is immortal. I cannot say that I have come to this conclusion because it is the more â€Å"plausible† answer, but rather a belief in my faith that this life is temporary and all souls are eternal. While I understand that this view isn’t completely in line with Plato’s, I think Plato’s is closer than Aristotle’s to mine. Aristotle. "De Anima." Basic Works of Aristotle. Ed. Richard McKeon.

A Change For Jane

Her name was Jane Hulsebosch.   She was my math teacher for fifth and sixth grade. Jane was a tall large woman with black tight curly hair. Her eyes were brown and beady, like a ferret. She was approximately five feet and eleven inches tall, but to me she seemed much taller. Jane did not stand, she loomed. If she looked over my shoulder while I took one of her labyrinthine exams, it felt like the sword of Damocles swinging over my head. Jane was an extremely heavy woman who was plagued with varicose veins. When I was young, however, it looked like she had beanbags stored under her skin. Jane was a heavy smoker. I could not help but notice the stale smell of smoke on her fingertips as I gingerly approached her desk with a paper to grade.Jane to me was the educational equivalent of terrorism. I was not stupid enough to actually volunteer an answer to her questions. I attempted, like my other poor unfortunate classmates to crawl into a crevice in the floor by keeping my eyes downcast. Silly me.Like a panther circling its prey Jane walked around our classroom. Employing the Socratic Method, she barked questions at me. And I, paralyzed in fear, failed yet again to answer correctly. The woman was an insidious masochist. I know she delighted in terrorizing us. She threw erasers and chalk at us with the precision of a stealth bomber while wailing â€Å"DOPEY!†My morning prayer was that Mrs. Jane Hulsebosch die a long painful death. In my head I painted glorious medieval deaths. My personal favorite fantasy was one where she is disemboweled. My classmates, however, preferred the â€Å"drawn and quartered† method. God it seemed, never answered our prayers.Then one cold damp winter morning it seemed that God did answer me, well sort of.Jane entered the classroom but her gait was unsteady. She smelled like something I had never identified until I was in college. She smelled like a brewery.Her face was swollen, like someone who just got pummeled in the face during a game of dodge ball, but worse. Was that a black and blue that I saw?   I did not know, and did not care to draw her attention to the fact that I was staring at her. Quickly, I l ooked at my textbook and pretended I was reading.A haunted silence filled my classroom. All of us just sat holding our breath. My stomach felt like there was a lead balloon in it. (Indeed, as I write this paper, the feeling sets in.) What did we do? Did we do something so terrible that we rendered her speechless?Did Sean get caught cheating again? After what seemed like hours, two police officers entered our classroom along with the principal. What was happening? Were we being arrested for being bad students like she promised? Was the threat of our behavior going on our â€Å"permanent record† happening now?No. Jane was being led out of our classroom. Suddenly, as she passed my desk I was compelled to look up at her and a tear hit my shoe.Outside, someone was wailing. It was Jane, but it was not the same yelling that she did in class. What was happening? Our principal entered the classroom and told us that he would be teaching us for awhile and that we should all pray for our teacher.Well, we did†¦but not for her return. That night I remember my parents whispering in hushed horrified tones and then calling me into their bedroom to â€Å"discuss something†.   I was asked an interminable amount of questions about Jane, the throwing, the yelling and that smell.   Jane, they told me was in the hospital. Her husband had been beating her and she had a drinking problem.

Art in ancient greece essays

Art in ancient greece essays Art is the creation of beautiful; or thought provoking works. Art went through a tremendous amount of development in ancient Greece from the archaic to the Hellenistic eras. Much of the development was due to the political and philosophical views of the era. Each era gave way for the changes in the following era. During the archaic period there was a growing elevation of individualism. Individuality and uniqueness, virtually an awareness of self was a main issue within art ands philosophy. In archaic Greece there was increased prosperity and mobility this allowed for old ways of life to be overcome and people were more susceptible to finding ones self in other words individuality stood out. Poetry and sculpture show a more personal approach and attention to intellectual and personal detail. Personal feelings were reflected within art. In poetry men and womens sexuality and feelings about sexuality were free territory to discuss a practice which was uncommon prior to this period. Sculpture emerged as a principle form of artistic expression. There were magnificent statues of nude walking youths. Draped female sculptures from the archaic period suggest Middle Eastern influence. Philosophy at this time was moving away from religion, and concentrated on the awareness of self, philosophy and art had a central focus of self. Archaic art is a silent witness to the extraordinary development western society was about to undertake. The art of the classical Greek style id characterized by a joyous, freedom of expression and I celebrates mankind as an independent entity. Artist of this period began to express the human figure in a more naturalistic manner. Their forms were more true to life, but they approached an ideal vision. Classical sculptures became natural. The sculptures completed the process begun by their archaic forbearers of mastering the accurate representation of the human body. Classical vase p...

Analysing Sunnis And Shiites Split Religion Essay Essays

Analysing Sunnis And Shiites Split Religion Essay Essays Analysing Sunnis And Shiites Split Religion Essay Paper Analysing Sunnis And Shiites Split Religion Essay Paper The difference between Sunni and Shia religious orders of Islam are non to the mammoth proportions as most Western literature assume. It is true that there are minor fluctuations in the manner they take their several spiritual caputs and attribute significance to the history of the household of Muhammad s, nevertheless, cultural and political differences hold the most dissentious power over the spiritual forces. It is hence important to observe that both religious orders believe and put accent in the Five Pillars of Islam, believe in and read same Holy Quran, and moreover see each other Muslims. The five pillars that form the nucleus of their religious holiness are Testimony of religion ( Kalima ) , Prayer ( Salat ) , Almsgiving ( Zakat ) , Fasting ( Sawm ) , Pilgrimage ( Hajj ) ( Huda, 2010 ) . The split between the Sunnis and Shia can be traced back to the decease of the Prophet Muhammad, and the quandary of the replacement of Muhammad as the leader of the Muslim state. Prophet Muhammad died in the eventide of June 8, 632 A.D. ( the twelfth of Rabi al-Away ) at the age of 63. There after, the Sunni Muslims were in understanding with the base taken by most of the Prophet s comrades that the new caput should be chosen from among those deemed competent of the occupation. This is the place that was adopted and implemented. The Prophet Muhammad s close familiarity and counsellor, Abu Bark, accordingly became the first Caliph of the Islamic state. It is deserving observing that the word Sunni is an Arabic word significance one who follows the traditions of the Prophet. Contrary to the Sunni belief over the sequence, some Muslims hold the thought that leading should hold been from the Prophet s ain household, handed over to those specifically appointed by him, or amid Imams chosen by God Himself. These were the Shia Muslims. They believed that after the decease of Prophet Muhammad, leading ought to hold been passed on straight to his cousin/son-in-law, Ali. Since those historical old ages, Shia Muslims have non acknowledged the power and authorization of elective leaders. The Shia Muslims alternatively opted to acknowledge and obey the Imams they believed were chosen by the Prophet Muhammad or by God Himself. The word Shia is an Arabic word for a group or supportive party of people. It is short signifier of Shia-t-Ali, or the Party of Ali. Shias are besides referred to as followings of Ahl-al-Bayt or Peoples of the Household ( of the Prophet ) ( Huda ) . Majority of the Muslims are the Sunni Muslims at 85 % of all the Muslims allover the universe. A touchable figure of Shia Muslims are found in Iraq and Iran, with some big minority communities in Syria, Yemen, Lebanon, Bahrain etc. Having looked at the brief history of the split of the two religious orders and the grounds behind the split, it is cardinal hence, to look at the differences in spiritual belief s, leading, texts, and any other that may be. From the historical differences in political leading, some religious life facets were accordingly changed and since diverge between the two groups. However, as note hitherto, the Shia and Sunni Muslims clasp in common the cardinal articles of Islamic belief and are brethren in the Islam religion. As a affair of fact, seldom or neer at all will a Muslim identify themselves as Shia or Sunni Muslim but instead as Muslim ( Austine Cline ) . Shia Muslims believe that the Imam is of course impeccant since his authorization comes straight from God. From this, the Shia Muslims revere and adore the Imams as saints and strive to execute pilgrims journeies for Godhead intercession to their shrines and graves. Countering this is the Sunni Muslim belief that there is no foundation in Islam for a familial advantaged class or rank of spiritual leaders. They hence have no topographic point for the pilgrims journey to the saint s shrines. Sunni Muslims argue that control of the community is non familial or a birthright, but a trust that must be earned and hence can be given or taken away by the people themselves. Another difference comes in the holiness of spiritual texts. Shia Muslims have some bitterness to some of the coevalss of the Prophet Muhammad. This sprouts from their bases and workss in the historical old ages of strife about leading among the Muslim nations. It is said that Abu Bakr, Umar, Aisha, etc ( Sunnis ) narrated much about the Prophet Muhammad s life and religious brushs, pattern and journey. The Shia Muslims reject these Hadith do non take them as a footing for their spiritual patterns. This consequently informs divergency in spiritual pattern between the Sunnis and Shias. The differences concern facets of spiritual life: supplication, fasting, pilgrims journey, and so on and so forth. For case Shiites can distill the five day-to-day supplications into 3 or 4 yet Sunnis do nt, Shiites might pay their alms ( Zakat ) straight to the hapless, yet Sunnis wage to the province. Shiites besides promotes a probationary matrimony ( muttah ) for work forces going far from place whi le Sunnis do nt impute to this ( Sunnis vs. Shiites ) . The Shias place their brow onto apiece of natural stuff while praying ( clay tablet, dirt or sand from Karbala ( where Imam Hussain was martyred ) , instead than onto a supplication mat. The Sunnis nevertheless recommend that one should non bow down on a natural surface. Shias hold their custodies at their sides while praying while Sunnis on the other side their arms-right over left- and clasp their custodies, though either is acceptable. Religious Shia adult females black like the male spiritual leaders. Conventional Sunni adult females cover around the margin of the face with the hijab but merely to below their mentum such that the mentum can demo in portion while the Shia adult females will cover the margin of the face and the mentum wholly. Shias more frequently than non deduce their name from the name or rubrics of saints. They frequently draw their line of descent from to Ali and Fatimah. The three Sects of Shiites Although, through history there were several subdivisions of Shia Muslims, presently merely three are prevailing. The Ashariyyah, deeply called the Twelvers, the Ismaili and the Zaidi. Ashariyyah or Twelvers as the disciples are called believe in the 12 divinely ordained leaders, known as the Twelve Imams. These were the replacements of Prophet Muhammad and were religious and political leaders. On mean 85 % of Shia are Twelvers. Ismaili is the 2nd largest religious order of the Shia Islam after the Twelvers. They derive their name from their credence of Ismail ibn Jafar as the divinely-appointed religious replacement to Jafar as-sadiq, they differ from the Twelvers, who accept Musa al-Kizim, the younger brother of Ismail, as the proper Imam. Zaidi are followings of the Zaidi fiqh and they identify with the first four of the Twelve Imams but they accept Zayd ibn Ali as their Fifth Imam, in topographic point of his brother Muhammad al-Baqir. After Zayd ibn Ali, the Zaidi acknowledge other posterities of Hasan ibn Ali or Husayn ibn Ali to be Imams. Among the well known Zaidi Imams are Yahya ibn Zayd, Muhammad al Nafs az-Zakiyah and Ibrahim ibn Abdullah.

Social Welfare in America Research Paper Example | Topics and Well Written Essays - 1000 words

Social Welfare in America - Research Paper Example The great depression of 1930s had devastating effects to the citizens of United States. Legislatures of that time took an initiative to create Social Security act in 1935, which influenced programs such as pension schemes, address issues touching on the unemployed, and children welfare (Alexander 5). Cushion families from financial difficulties was the intention of the social security act. The government stability depends on its ability to address factors influencing the wellbeing of its people. President Roosevelt’s regime lingers in the minds of the Americans whenever they discus social security programs. US legislatures amended the social security act in 1939 to cater for unemployment compensation (Tushnet 125). Unemployed are susceptible to hard life conditions, which can drive them into committing social crimes as a means to cater for their needs. The program intended to provide stipends, which would cater for their basic needs. Federal government created agencies, which could oversee welfare programs in United States. The agencies created through 1939 social security act include Department of Health and Human Service (HHS), Labor Department, Education, Agriculture, and Urban Development and Housing (Caputo 231). Each department addresses issues affecting US citizens. For instance, the department of agriculture addressed influences that originate from agricultural production in the nation. Education department ironed issues, which influenced acquisition of education in the United States. Historians believe that US welfare has been able to address critical issues, which influence human development (Handel 143). In 1965, US passed a social welfare act, which influenced the lives of elderly persons in the nation. The intention of the act was to compensate old persons by creating a kitty, which would cater for their wellbeing. The elderly have the challenge when it comes to finances, which would settle their bil ls in the society. The elderly compensation program has enabled many elderly persons to lead a positive life after retirement. In 1996, US government passed Personal Responsibility and Work Opportunity Reconciliation Act (Epstein 46). The intention of the act was to address poverty effects in the society. The growing number of the poor in US was worrying and the government had to develop strategy, which could influence their lives. The act gives the federal government the power to direct funds to various states to cater for the poor. Assisting the poor accords human rights because the government has the mandate to protect the poor (Reintsma 212). Largely, the protection of the poor as stipulated in the in the constitution is a reality through this act. Medicare provision to US citizens has elicited debates on how the poor could benefit from the welfare program. The provision in the Medicare program is to ensure the US citizens can access quality healthcare. The program is in line wi th United Nations requirement, which intends to improve human health care as a basic requirement (Zastrow 136). Medicare social welfare program dates back to the time of President Johnson when United States had to compensate war veterans and their families for their contribution to

Law on Euthanasia Essay Example | Topics and Well Written Essays - 3500 words

Law on Euthanasia - Essay Example A common method of active euthanasia is the administering of barbiturates or sleeping pills. The distinction between passive and active euthanasia can be summed up as actually doing something to bring about the death of a patient or doing nothing to save the patient's life. Predictably, euthanasia is the subject of much debate as it generates emotional consideration of moral and social values making it difficult for judges in the U.K. to formulate and adhere to a strict legal code. Each case has to be decided on its own merits. Each time social and moral issues have to be delicately balanced against the applicable law. In 1993, Lord Browne-Wilkinson in the House of Lords, explained that, "The judges' function in this area of the law should be to apply the principles which society, through the democratic process, adopts, not to impose their standards on society. If Parliament fails to act, then judge-made law will of necessity through a gradual and uncertain process provide a legal answer to each new question as it arises. But in my judgment that is not the best way to proceed."(Airedale N.H.S. Trust v Bland 1993) Lord Browne-Wilkinson went on to say, "For these reasons, it seems to me imperative that the moral, social and legal issues raised by this case should be considered by Parliament. " (Airedale NHS Trust v Bland 1993) Public opinion is sharply divided in cases of euthanasia. There are those opposed to any form of euthanasia on the grounds that it requires passing judgments on the quality of the patient's life. The opponents to euthanasia conclude that refusing to administer medical treatment to a patient or actively discontinuing a patient's medical treatment is morally wrong. On the other hand, those in favor of euthanasia argue that the patient is only suffering with no relief in sight, and therefore to keep the patient alive when he is for all intents and purposes, dead, is morally wrong. This is the moral and social background that makes it difficult for courts to apply strict legal guidelines. The moral and social implications were considered in both Re A [2000] HRLR 721 and Airedale NHS Trust v Bland [1993] AC 789. In Bland's case on appeal to the House of Lords, Lord Geoff said "This is because the question is not whether it is in the best interests of the patient that he should die. The question is whether it is in the best interests of the patient that his life should be prolonged by the continuance of this form of medical treatment or care." (Airedale NHS Trust v Bland [1993] AC) By saying this, Lord Geoff dispensed with the moral issue and identified the applicable legal principle upon the issue of euthanasia rests. Is it in the patient's best interests to that his life should b prolonged by continuing with the medical treatment. The court and the law is not concerned with social implications or moral values. The court and the law is only concerned with the patient himself. What is best for him, as opposed to society will guide the court. To better understand this application of legal principles and the disposal of moral

Time Management Essay Example for Free

Time Management Essay Time Management in the Business World It is true that the majority of the time, people learn to manage their time the proverbial hard way (i.e. working late at night, trial and error, barely meeting deadlines, etc.). The definition of time management can be stated to be the process of both controlling and understanding the time spent on a variety of activities. Time management is by and large affected by a variety of certain methods, techniques that are utilized to accomplish the goals, objectives and tasks at a company within a particular time frame. Time management has typically been discussed in business sectors, however, throughout the years; there have been an incorporation of personal activities within the topic. Literature has noted that how one manages their time is a fundamental question that should be inquired upon within the business management arena. The subject of what is time has also been expressed in the business area in order to get individuals to better understand how to utilize it more effectively and more efficiently. The definition of effectiveness is being able to accomplish a given project in a prudent manner; while efficiency operates on ensuring that the tasks associated with the given project run as smoothly as they possibly can (Adair and Allen, 2003; Covey, 2004; Saunders et al., 2004). Ritter (1989), Irons (2003) and Schwartz and McCarthy (2007) ruminate that the core issue surrounding time management is that time is a resource that is restricted and that employees have to have energy for a business to run successfully. Schwartz and McCarthy (2007) took a step further by stating that the behaviors and rituals associated with employees at companies have a direct effect on that companys revenue and reputation in addition to the factors of performance and productivity. Hence, time management becomes an even more precise concept to both analyze and examine in order that businesses function to the best of their ability (Jex and Elacqua, 1999). Time management is a â€Å"balancing act† ( Friemann, 2000). Employees and staff at certain companies and corporations have problems with time management mostly as a consequence of not learning how to manage their time prior to entering  into the career world (Chase, 2003; Gamauf, 2012), personal and/or workplace stressors (Adebisi, 2013) and a lack of discipline (Viswanathan and Olsen, 1992; Kay, 2011; Mancini, 2003). To combat the issue of time management, certain journal articles have posited that management needs to implement certain types of strategies that help employees, managers and staff manage time well within certain projects and tasks that they are given (Anonymous, 2009; Chesbrough and Appleyard, 2007; Oshagbemi, 1995; Oncken and Wass, 1999; Nagra, 2011). There is reason to believe that certain strategies along the lines of goal setting (Irons, 2003), Pareto analysis; and quadrant goal implementation also referred to as the Eisenhower Method (Adair and Allen, 2003; Mancini, 2003; Thatcher, 2006), as well the my time or yours strategy noted in (Saunders et al., 2004), which outlined the importance of time management for companies and corporations that operate on both virtual teams and what would be perceived as the typical 9-5 work routine. Certain literature has even posited that certain strategies work better at particular times of the year (Bingham et al., 2011). What essentially the n is the best practice associated with time management? How can companies and corporations ensure that their staff is managing time to the best of their ability so that they run smoothly? Statement of the Problem Time management is a problem. Many companies and corporations often suffer at the hands of goals and projects not being completed on time. This results in cutbacks, frustrated employees and workers who are not being recognized accordingly (i.e. appraisals, compensation) (HRLook.com, 2007; Mancini, 2003) and a lack of output for the companys products. While trial and error is typically the best way individuals learn to manage their time better, it becomes all the more important in the business management setting that time is managed, and managed properly; just not at the expense of the employees, managers and staff. Description of the Problem The focus of my research then will be to determine the best strategy (ies) that companies can implement to curtail the issue of time management. What courses of actions and methods best suit all sectors? While that is a loaded question, as there are many strategies that can be put into motion within  companies and corporations, there is rationale to ascertain that one strategy or two at a minimum can be employed in all areas of business management (in all sectors). As aforementioned, there are many different courses of action that a company can take in terms of aiding employees and staff to manage their time better so goals are properly executed. Stephen Covey (2004), in his book, The Seven Habits of Highly Effective People stated that time management could be approached from any of his four categories: first generation, which was noted to be based on timepiece, whose job is alerting individuals that a duty needs to be completed; second generation, which was more along the lines of planning solely based on setting goals; third generation, which was a prioritization technique utilizing certain objects daily to elucidate priorities efficiently and fourth generation, which was a blend of the first through third categories with urgent matters taking precedence (Covey, 2004). Perhaps, his discussion on time management can be expounded upon in the research to better understand what strategy actually works and what does not, the best. Definition of Key Terms Each of the presented key terms will be used throughout the research to highlight the topic of time management in the business sector. * Attention management which relates to an individuals devotion of the resources mentally to a particular outcome or task (Mancini, 2003; Warren, 2008). * The action item which is defined as what needs to take place within a particular task (Mancini, 2003). * Chronemics the study of nonverbal contact within the field of business management. Perceptions associated with interfacing and promptness fall within the realm of chronemics (Mancini, 2003). * Goal Matrix – technique associated with prioritizing what is most essential to be completed (Mancini, 2003). * Pareto Analysis – a statistical technique used to have efficient use of resources (Mancini, 2003). * Prospective memory – which is remembering to perform tasks when they are needing to be performed (Srivannaboon and Milosevic, 2006). * Perception of time – a psycholog ical term that refers to the subjective interpretation of what time is (Adair and Allen, 2003; Dight, n.d.). * Time management systems – tools that aid and support employees and staff to better manage their time (Mancini, 2003). Purpose of Study/Methodology Literature will be examined regarding time management. Each of the terms presented will be explicitly defined and discussed. In addition to the literature, questions will be asked throughout the research paper regarding time management such as why has certain strategies been more effective than others throughout the years; is it a manager’s job to motivate their staff to properly carry out duties; what has happened to companies that did not employ any kind of time management skills and strategies to their business; why is time management such an issue; can time management really be trained. In addition to these questions being answered in detail, much attention will be paid to the types of strategies associated with time management. Common strategies and not so common strategies will be important. With the methodology area of the research paper, interviews and/or surveys will be needed to assess and examine how individuals manage their time. While the crux of the research paper is on time management in business, time management is an important component in daily living as well. Thus, the function of the interviews and/surveys will be twofold: to delineate whether time management is a problem or is it laziness; and whether certain strategies that are being implemented by individuals in their daily activities can be incorporated into the business arena and vice versa. This will serve to highlight both the importance of time management and efficient use of time. Additional methodologies may arise throughout the course of the research that may lend itself to more literature reviewing, and analysis of a quantitative nature. Presently, there appear to be no limitations with this particular scope of topic, given the considerable and vast amount of information on it. While that does not contend that limitations will not present themselves over the course of the research, it can be posited that the research question will be answered.

False Positives In Presumptive Blood Testing Biology Essay

False Positives In Presumptive Blood Testing Biology Essay Blood is a fluid medium that is found within the cardiovascular system-which comprises of the heart and blood vessels (Jackson and Jackson 2008). It consists of 55% blood plasma and 45% cellular material (Jackson and Jackson 2008). Blood plasma consists of dissolved materials such as antibodies, hormones, waste products and nutrients, whereas the cellular material consists of erythrocytes (red blood cells), leucocytes (white blood cells) and thrombocytes (platelets) (Jackson and Jackson 2008). Blood is transported through the body by the pumping action of the heart. It has numerous functions including (Jackson and Jackson 2008): Acting as an internal transport system-including the removal of waste products for excretion and moving nutrients for metabolism. Maintaining body temperature. Defending against infection. Protecting the body from effects of injury. Blood is one of main sources of DNA found at crime scenes, and is crucially important in establishing a link between a suspect and a victim of a crime (Jackson and Jackson, 2008). To detect the presence of blood at a crime scene, a presumptive test is used. These can, however, only detect whether a substance is blood and cannot distinguish between human and animal blood-a serological test is needed to do this. The Erythrocytes (red blood cells) are the most common type of blood cell and contain haemoglobin (Jackson and Jackson 2008). They contain haemoglobin- a protein containing iron. Haemoglobin is responsible for the carriage of oxygen, and it is this property that presumptive blood tests are based on. Most of the presumptive tests rely on the ability of haemoglobin to catalyse the oxidation of a reagent, normally hydrogen peroxide (H2O2 (aq)) (Jackson and Jackson 2008). The result of oxidation normally produces a colour change in the presumptive test. Tiny amounts of blood present as a scene can be detecting using a colour change test. Some old and dried stains look similar in appearance to blood which can lead to a scenes of crime officer conducting a presumptive test. Other substances that could have contaminated suspected blood or other substances on their own at a scene could lead to a presumptive blood test incorrectly showing a positive result for blood. This is known as a false positive. Once a stain has been determined as blood, then two processes must be completed. The first is to interpret any bloodstain patterns, so that a reconstruction of events can be established (Langford et al 2005). Secondly, bloodstains must then be recovered for further analysis (Langford et al 2005). Recovery of bloodstains varies according to whether the stain is wet or dry. Once recovered, the blood can then be sent to a Forensic Science Service laboratory, where it will be initially tested to ascertain whether it is human or animal blood. To do this a serological test will be conducted, which involves identifying the presence of proteins specific to humans and analysing for DNA sequences specific to humans (Jackson and Jackson 2008). The blood will then be used for DNA profiling, which will hopefully establish whether the blood belongs to the suspect or the victim. I.II Aims and Objectives The aim of my project is to create a definitive list of false positives for four different presumptive blood tests. Within this aim I have six objectives to complete: To compare the false positives of four different presumptive tests. To test substances that are known false positives- as reported by other authors. To test unknown substances allied to those already known. To record the time taken for a substance to react with a presumptive test. To photograph the results of from each substance. To create a definitive list of false positives for each presumptive test. I am going to compare four different presumptive tests, as some tests are more practical to use in some situations than others. Consequently, analysing more than one test will allow a wider range of results. I shall also be testing known false positives as reported by other authors, as it is important to show how the presumptive tests react. Unknown substances allied to those that are known will then be tested to see whether similar substances react alike. This will then allow me to establish whether an unknown substance has reacted or not, as I can compare the reaction times and colour changes from both the known and unknown substances. It is important to record the time taken for a substance to react with a presumptive test, as blood should show a result straight away. An unobvious result that takes time to develop could indicate that the substance being tested is a false positive. Photographing results will allow me to document the differences in the colour change in each reaction with each substance. I feel that it is important to create a definitive list of false positives as it can reduce the risk of using valuable resources at a crime scene. For example, if a scenes of crime officer is informed that a possible blood stain has been contaminated with horseradish (a known false positive), then they can use a presumptive test for blood that is not known to produce a false positive with horseradish. If the result is positive for blood, then serological tests for blood can be carried out. Overall, I hope that this project will aid the work of a scenes of crime officer to choose the correct presumptive test to use in different situations-minimising time spent and resources used. Chapter II. Literature Review II.I Background Information The scientific analysis of blood was initially mentioned in 13th century Chinese texts, but it was Karl Landsteiner who discovered the modern science of blood typing, which categorises different types of blood into the ABO blood typing system (White 2010). In 1901 it was reported that blood could be determined in two week old serum stains on linen, and by 1902 the four blood types A, B, O and AB had been discovered (White 2010). This system is based on types of antigen on the red blood cells membrane. An antigen is a protein molecule capable of binding on to an antibody (Erzinà §lioglu 2004). The ABO system uses two antigens which are known as A and B; and the four blood groups are determined according to this system (Erzinà §lioglu 2004). People that have the blood group A have the A antigen, those that are group B have the B antigen; those in the AB category have both antigens and those who belong to the O group have neither antigen (Erzinà §lioglu 2004). A persons blood contai ns the opposite group of corresponding antibodies, so people with blood group A have b antibodies, people with blood group B have a antibodies, those with blood group AB have neither a or b antibodies and those with blood group O have both a and b antibodies (Erzinà §lioglu 2004). If the wrong antibodies are introduced into the wrong blood group then death can be a result due to the red cells clumping together. The first suspect to have been convicted largely on the basis of DNA analysis of blood samples was found guilty at Leicester Crown Court on 22nd January 1988 (White 2010). This case marks an important milestone, and DNA technology has become commonplace in forensic laboratories and is now instrumental in establishing both guilt and innocence in court cases (White 2010). II.II Physical Properties of Blood Blood constitutes about 7.7% of the body weight of a person (White 2010). This equates to 5-6 litres in males and 4-5 litres in females (Tortora and Anagnostakos 1987). Viscosity is resistance to flow, which in fluids is compared to water which has a viscosity of 1. (Bevel and Gardner 2002). Blood viscosity usually ranges between 4.4 and 4.7 (Tortora and Anagnostakos 1987). Blood also has a higher specific gravity (density) than water, which is the weight of a substance relative to the weight of an equal volume of water (James and Nordby 2005). Blood is a fluid that circulates throughout the body by way of the heart, arteries, veins and capillaries-known as the circulatory system (James and Nordby 2005). A primary function of blood is to transport oxygen, electrolytes, nourishment, hormones, vitamins and antibodies to tissues and to transport waste products from tissues to the excretory organs (James and Nordby 2005). Tortora and Anagnostakos (1987) (in Bevel and Gardner 2002) say that when 4-6 litres of blood is present in the circulatory system, it is distributed as follows: Figure 1- Blood Distribution in the Circulatory System (Tortora and Anagnostakos 1987) As a medium, blood is composed of 55% plasma and 45% cells (White 2010). A single drop or large volume of blood is held together by strong cohesive molecular forces that produce a surface tension (James and Nordby 2005). Surface tension is defined as the force that pulls the surface molecules of a liquid toward its interior, decreasing the surface area and causing the liquid to resist penetration (James and Nordby 2005). Bevel and Gardner (2002) state that plasma is the pale yellow fluid component of blood, which is broken down by volume into 91% water, 8% protein, 1% organic acids and 1% salts. Fibrinogen is one of the proteins, and this plays an important role in the clotting of blood (Bevel and Gardner 2002). Blood serum is blood plasma minus its protein content (Jackson and Jackson 2008). The cellular component of blood consists of erythrocytes (red blood cells), leukocytes (white blood cells) and thrombocytes (platelets) (Bevel and Gardner 2002). Red blood cells are heavier than plasma, which can be seen in bodies as lividity-which is where red cells settle to the lowest extremity of a body after death (Chmiel and Walitza 1980). http://people.eku.edu/ritchisong/301images/Red_White_Blood_cells.jpg Figure 2- A red blood cell, platelet and white blood cell (University of Eastern Kentucky 2010). There are roughly 4.8 to 5.4 million red blood cells per cubic millimetre of blood (Tortora and Anagnostakos 1987). They are bioconcaved discs in shape. The main role of the red blood cells is to transport oxygen from the lungs via the arterial system and return carbon dioxide to the lungs for expiration via the venous system (James and Nordby 2005). Red blood cells contain haemoglobin which is a red pigment that gives blood its colour (Bevel and Gardner 2002). Haemoglobin is composed of globin, which is made up of four folded polypeptide chains, and four haem groups that join with iron (University of Eastern Kentucky 2010). http://www.ul.ie/~childsp/CinA/Issue64/Images/TOC36_2.gif Figure 3- Haemoglobin, containing four haem groups (University of Limerick, 2010). As the oxygen content increases in the blood, the bright red pigment of the haemoglobin also increases (Bevel and Gardner 2002). A red blood cell does not contain a nucleus. Red blood cells are expressed as a percentage of the packed (red) cell volume (PCV), also known as the haematocrit (Wonder 2001). Nelson and Rodak (1983) state that the haematocrit in humans is variable between individuals. Haematocrit Possible people with range of haematocrit 15-29% Chronic alcoholics or drug abusers, steroid abusers, women after traumatic child birth or illegal abortion, malnourished homeless, elderly. 30-48% Normal range for nontraumatic venipuncture (blood drawn in a clinic or hospital) samples. 49-75% Dehydrated individuals, people in shock, those living at high altitude, impending and active heart attack victims, newborn babies, people suffering from hypothermia, and people after extreme exercise. Table 1- Table to show the range of haematocrit ratios (Wonder 2001). White blood cells act to fight infections, destroy old cellular material and to destroy other invading microbes (Bevel and Gardner 2002). White blood cells can be further subdivided into phagocytes which are responsible for the capture and ingestion and foreign substances, and lymphocytes- which are responsible for the production of antibodies (Jackson and Jackson 2008). They make up less than 1% of the cellular component of blood, which equates to 5000 to 9000 white blood cells per cubic millimetre (Tortora and Anagnostakos 1987). The nuclei of white blood cells are the source of DNA in the blood (James and Nordby 2005). The other part of the cellular component of blood is the platelets. Like red blood cells, platelets also lack a nucleus (Bevel and Gardner 2002). Bevel and Gardner (2002) say that there are generally about 250,000 to 400,000 platelets per cubic millimetre of blood. Platelets are major components of the clotting mechanism of blood, and this is their primary function (James and Nordby 2005). Platelets have irregular shapes and are normally quite small, however when they encounter a damaged blood vessel they increase their size and their shapes changes (Bevel and Gardner 2002). They also become sticky and adhere to surrounding fibres in the vessel wall, which results in the accumulation of platelets called the platelet plug (Bevel and Gardner 2002). II.III Blood at a Crime Scene Blood is normally found at a crime scene due to a person sustaining an injury either by accident or on purpose. When a breach in the circulatory system occurs- due to an injury- the body reacts in different ways to control the loss of blood (Bevel and Gardner 2002). Initially the vascular spasm occurs, which is which the smooth vessels in the blood vessel wall contract to decrease the size of the vessel, which reduces the flow of blood through it (Bevel and Gardner 2002). Tortora and Anagnostakos (1987) say that this reduces blood loss for up to 30 minutes following injury, which gives time for the other blood loss mechanisms to engage. The platelet plug then follows which reduces, if not stops, the blood loss (Bevel and Gardner 2002). The final step is coagulation, or clotting. This is what is normally seen at crime scenes, where the clotted mass of fibrin fibres and blood cells is surrounded by blood serum (Bevel and Gardner 2002). There are three types of bleeding that can occur from damage to blood vessels (BUPA 2009): Arterial Bleeding Venous Bleeding Capillary Bleeding. Arterial bleeding usually is spurting bright red blood, due to the blood having come from the heart and lungs-so it is oxygen rich (Walter et al 2004). The pumping action of the heart adds rhythmic surges to move blood vessels away from the heart (Wonder 2001). It is the most serious type of bleeding, and the most difficult to control due to the blood in the arteries being under pressure from the heart (Walter et al 2004). Arterial wounds results in volume stains (Wonder 2001). Loss from the carotid artery or the aorta can rapidly lead to death (Wonder 2001). Examples of arterial injuries, and how they may occur are listed in Table 2. Artery Location Probable Occurrence Facial Mouth/lips Beating Temporal Head/temples Gunshot, Crushing Carotid Neck, front throat Stab wound, Gunshot, Decapitation Subclavian Under collar bone Gunshot, Crushing Aorta Chest Gunshot, Stab wound Brachial Arm/elbow Bone break Radial Wrist Slit wrists, Bone Break, Stab wound Femoral Groin Gunshot, Stab wound Tibial Ankle Bone Break, Crushing Deltoid Upper arm muscle Stab wound Table 2- Areas and actions that may involve arterial damage (Wonder 2001) External venous bleeding is normally as a result of wounding, as veins are closer to the skin than arteries (Walter et al 2004). It results in the steady flow of dark red (almost brown) blood, and is darker than arterial blood as it has released oxygen to the tissues in the body and is flowing back to the heart and lungs for more oxygen (Walter et al 2004). Capillary wounding is common in minor wounds as capillaries are very small vessels that are under very little pressure with a low volume of blood (Walter et al 2004). Capillary bleeding results in the oozing of either bright or dark red blood, which will normally stop on its own (Walter et al 2004). As well as the three main types of bleeding, there is a further category which is traumatic bleeding. There are different types of wounds which can cause traumatic bleeding, and these can be categorised as follows: Abrasion- also known as a graze, where an object brushes on the skin but does not break it. Hematoma- where blood vessels are damaged, causing blood to collect under the skin. Laceration- where a blunt impact to soft tissue causes a deep wound. Incision- where a precise cut is made into the skin. Puncture Wound- where an object penetrates the skin and deeper layers. Contusion- also known as a bruise, where a blunt trauma causes damage under the skin, but does not break it. Crushing injuries- where a great amount of force is applied over a period of time, causing initially internal bleeding. Ballistic trauma- where a projectile weapon has entered and exited the area of the body, causing a wound between the two. Scenes of Crime officers attend many types of crime scene where blood is present. These include: Burglary- When an offender breaks a glass window or door to gain entry to a premises, they risk cutting their hands/arms. This leads to blood being left on fragments of glass in the window and on the floor. Assault/Wounding- Open wounds are normally the result of an attack on a victim. Blood can be left at an assault scene on the weapon that was used in the assault, on the ground, on the offender and on the victim. If the victim is bleeding heavily then blood will be left whenever the victim comes into contact with another surface. Manslaughter/Attempted Murder/Murder- Blood left at these scenes is not only important for swabbing purposes, but the pattern in which the blood is left can determine the order of events at a major scene. Road Traffic Crash- Blood at this scene can be found in the victims car and, if involved, the offenders car. This is important as it can place people in their respective cars- allowing investigators to work out the positions of people at the time of the incident. The collection, packaging and preservation of blood evidence at a crime scene should not take place until the scenes of crime officer has documented the bloodstain patterns (Lee, Palmbach and Miller 2001). Whenever biological fluids are encountered at a crime scene, protective clothing, gloves and masks should be worn due to the biohazard nature of blood (Lee, Palmbach and Miller 2001). To recover dry blood, an area near the blood that is unstained should be swabbed using a sterile swab, as a control sample (Derbyshire Constabulary 2008). Then, the stain should be swabbed using a sterile swab that has been moistened using sterile water (Derbyshire Constabulary 2008). The remains of the stain should then be dry swabbed using a sterile swab (Derbyshire Constabulary 2008). The swabs should be returned to their tubes immediately and stored frozen as soon as possible (Derbyshire Constabulary 2008). A batch control of both the water and swabs should always be made, and should be exhibited separately to the swabbed stain and background control (Derbyshire Constabulary 2008). Items that have areas of dried blood on them should be packaged in paper bags which are sealed securely and clearly marked as biohazard. Blood and bloodstained evidence should never be packaged in airtight containers (Lee, Palmbach and Miller 2001). To recover wet blood, a control swab of the surrounding area of the stain should be taken using a sterile swab (Derbyshire Constabulary 2008). The wet stain should then be swabbed using a dry, sterile swab (Derbyshire Constabulary 2008). The swabs should be returned to their tubes immediately, and should be stored frozen as soon as possible (Derbyshire Constabulary 2008). Again, a batch control of the swab should be exhibited separately (Derbyshire Constabulary 2008). If a removable item has an area of wet blood on it, then the entire object should be exhibited and left to dry in a drying room at the police station. Often at crime scenes, stains that are composed of unknown substances can easily be confused with blood. Identifying whether a substance is blood allows further analysis to confirm species, and the individual (Spalding 2006). II.IV Presumptive Tests for Blood James and Nordby (2005) say that a presumptive test is one which allows the scenes of crime officer to make a qualified conclusion that blood is present in the tested sample, when positive. They also say that when a test is negative, stains that need no further consideration are eliminated. Presumptive tests may be recognised as those that produce a visible colour reaction or those that result in the release of light (James and Nordby 2005). Both of these rely on the catalytic properties of blood to drive the reaction (James and Nordby 2005). Lee, Palmbach and Miller (2001) write this as a chemical reaction: AH2 + H2O2 Æ’Â   A + 2H2O Oxidisable chemical Hydrogen peroxide Haeme Oxidised (colourless) (peroxidise) James and Nordby (2005) state that catalytic tests involve the chemical oxidation of a chromogenic substance by an oxidising agent catalyzed by the presence of blood. They also say that the catalyst of the reaction is the peroxidise-like activity of the haeme group of haemoglobin. Cox (2004) describes the attributes that a good presumptive test for blood should be sensitive, specific, quick, simple and safe. In order for presumptive tests for blood to function properly, they must detect a component of blood (Tobe, Watson and Daà ©id 2007). Most presumptive tests therefore act on the peroxidise activity of haemoglobin. This component is not found in the everyday environment, but other substances found in items such as fruit and vegetables perform a similar function (Tobe, Watson and Daà ©id 2007). A very popular presumptive method is the phenolphthalein test, which is also known as the Kastle- Meyer test (Virkler and Lednev 2009). Lee, Palmbach and Miller (2001) say that the Kastle-Meyer test was introduced in 1901 by Kastle. Phenolphthalein will cause an alkaline solution to turn pink after it has been oxidised by peroxide when blood is present (Spalding 2006). The reagent consists of reduced phenolphthalein in alkaline solution, which is oxidised by peroxide in the presence of haemoglobin (James and Nordby 2005). The test result is normally immediate, and a positive result a minute or more after the test is performed is usually not considered as reliable (James and Nordby 2005). It has a sensitivity of 1:100,000 (Lee, Palmbach and Miller 2001). James and Nordby (2005) say that Adler and Adler in 1904 investigated the reduced or colourless form (leuco) of the dye malachite green, which is also referred to as McPhails reagent. This test involves the Leuco base of malachite green (Lillie 1969). Leucomalachite Green oxidation is catalyzed by haeme to produce a green colour (James and Nordby 2005). The reaction is usually carried out in an acid medium with hydrogen peroxide as the oxidiser (James and Nordby 2005). It has a sensitivity of 1: 20,000 (Lee, Palmbach and Miller 2001). Bluestar is a luminol preparation developed by Professor Loic Blum in France that is extremely sensitive and stable and produces a very bright, long lasting chemiluminescence (James and Nordby 2005). The extreme sensitivity of Bluestar Forensic allows detections of bloodstains down to 1:10,000 dilutions (Bluestar Forensic 2004). It does not require total darkness to be visible, and works well on either fresh blood or old bloodstains (Bluestar Forensic 2004). Bluestar works by mixing the Bluestar Forensic solution with Bluestar Forensic tablets, which is then left to dissolve. This is sprayed onto the area of suspected blood. A positive result will cause a bluish luminescence (Bluestar Forensic 2004). The Hemastix test, created by Miles Laboratories in 1992, is particularly useful when solutions can be hazardous, or inconvenient (James and Nordby 2005). The test consists of a plastic strip with a reagent treated filter tab at one end (James and Nordby 2005). The tab contains TMB, diisopropylbenzene, dihydroperoxide, buffering materials and non reactants (James and Nordby 2005). A bloodstain is tested by moistening a swab with distilled water, sampling the stain, and touching the swab onto the reagent tab on the strip (James and Nordby 2005). The tab is normally yellow, and turns form orange to green or blue when positive. Quality control testing is necessary and should be completed with known blood samples on every new batch of test reagents to verify that the reagents are working as expected (Lee, Palmbach and Miller 2001). II.V False Positives Sutton (1999) points out that a false positive is an apparent positive test result obtained with a substance other than blood. James and Nordby (2005) say that misleading results can be attributed to Chemical oxidants (often producing a reaction before the application of peroxide) Plant materials (vegetable peroxidises are thermolabile) Materials of animal origin (that contain traces of blood). Substances that produce false positives generally take detectably longer to react and, therefore, may be eliminated through observational interpretation (Tobe, Watson and Daà ©id 2007). False positives were initially noted only with copper salts (Glaister 1926). Tobe, Watson and Daà ©id (2007) state that saliva, semen, potato, tomato, tomato sauce, tomato sauce with meat, red onion, red kidney bean, horseradish, 0.1 ascorbic acid, 5% bleach, 10% cupric sulphate, 10% ferric sulphate and 10% nickel chloride are all known false positives. Bluestar False Positives (2008) say that Bluestar has false positives that include oil based paint, alkyd varnish, turnip, banana, leek, green bean, carrot, ginger, manganese sulphate, copper sulphate, iron sulphate and potassium permanganate. Lee, Palmbach and Miller (2001) write that many household cleaning products contain oxidising agents that can produce false positives. Many fruit and vegetables produce false positives including apples, horseradish and broccoli (Lee, Palmbach and Miller 2001). Bleach is a false positive that provides an (immediate and intense reaction) according to Gardner (2005). Hunt et al (1960) say that faeces often gave a false positive depending on the food that had been eaten previously. Ponce and Pascual (1999) state that lemon juice added to a bloodstain can cause a positive result due to its acidity. A false negative is when there is some interference with the oxidation-reduction reaction, normally in the presence of a strong reducing agent, which results in a delay of the oxidation reaction; thus resulting in a coloured formation (Lee, Palmbach and Miller 2001). False negatives are less common but problematic as an actual blood sample may be overlooked or left at the scene (Lee, Palmbach and Miller 2001). Many of the false positive reactions can be identified during the presumptive testing procedure if any changes observed and the exact point in the reaction of these changes is recorded and compared to that of blood (Lee, Palmbach and Miller 2001). Chapter III. Experimental Methodology I will be investigating known substances previously reported by other authors that show a false positive and then analysing other substances similar to those already known to see if these also produce a false positive. III.I Project Design Each of the substances will need to be repeated to ensure a wide enough range of consistent results. Therefore, a grid will be drawn on a piece of Perspex measuring 1.5m2, and a piece of filter paper placed in each of the grid spaces, to allow the even distribution of substances and to allow the easy identification of false positives.

For each of the presumptive reagents tested, the filter paper in each grid space will be exposed to a substance to be tested. This will be allowed to dry for a minimum of 1 hour. Each substance will then be tested with a reagent. Each substance will be repeated three times to give a fair indication of performance. The time taken for a substance to register a positive result will be recorded. If a colour change occurs then the test will be classed as positive. If no colour change is noted within 5 minutes of the reagent being added, then the test will be classed as negative. III.II Sample Preparation The substances that I have chosen to analyse are known false positives as reported by other authors and then substances allied to known false positives. Known false positives to be tested: Horseradish. Tomato Sauce. Red Onion. Turnip. Lemon Juice. Bleach Solution (5%). Unknown substances to be tested: Brown Sauce. BBQ Sauce. Radish. Dark Chocolate. Orange Juice. Bleach Solution (less than 5%). III.III Choice of Presumptive Tests I have chosen to use the following presumptive reagents to test substances for false positives: Kastle-Meyer. Hemastix. McPhails. Bluestar. III.IV Control Tests I will test all of the presumptive tests on blank filter paper before proceeding to test with substances. This ensures that there is no reaction from the filter paper to the presumptive tests. I shall also test all of the presumptive tests with horse blood before proceeding to test with substances. This shows that the tests do recognise a sample of blood. I have chosen to use 2.5g of each substance as I feel this is an amount that is representative of a stain at a scene. Blood is reported to have been diluted to 1:10000 in previous tests, and as this dilution has proved the most successful, I have chosen to use this dilution. REARRANGE + FINISH
