Police Technology - Forensic Science History

Police Technology - Forensic Science History Forensic science is a scientific method of gathering and examining the evidence. Crimes are solved with the use of pathological examinations that gather fingerprints, palm prints, footprints, tooth bite prints, blood, hair and fiber samples. Handwriting and typewriting samples are studied, including all ink, paper, and typography. Ballistics techniques are used to identify weapons, as well as voice identification techniques, are used to identify criminals. History of Forensic Science The first recorded application of medical knowledge to the solution of crime was in the 1248 Chinese book Hsi DuanYu or the Washing Away of Wrongs, and it described ways to distinguish between death by drowning or death by strangulation. Italian doctor, Fortunatus Fidelis is recognized as being the first person to practice modern forensic medicine, beginning in 1598. Forensic medicine is the application of medical knowledge to legal questions. It became a recognized branch of medicine in the early 19th century. The  Lie Detector An earlier and less successful lie detector or polygraph machine was invented by James Mackenzie in 1902. However, the modern polygraph machine was invented by John Larson in 1921. John Larson, a University of California medical student, invented the modern lie detector (polygraph) in 1921. Used in police interrogation and investigation since 1924, the lie detector is still controversial among psychologists and is not always judicially acceptable. The name polygraph comes from the fact that the machine records several different body responses simultaneously as the individual is questioned. The theory is that when a person lies, the lying causes a certain amount of stress that produces changes in several involuntary physiological reactions. A series of different sensors are attached to the body, and as the polygraph measures changes in breathing, blood pressure, pulse and perspiration, pens record the data on graph paper. During a lie detector test, the operator asks a series of control questions that set the pattern of how an individual responds when giving true and false answers. Then the actual questions are asked, mixed in with filler questions. The examination lasts about 2 hours, after which the expert interprets the data. Fingerprinting In the 19th century, it was observed that contact between someones hands and a surface left barely visible and marks called fingerprints. Fine powder (dusting) was used to make the marks more visible. Modern fingerprint identification dates from 1880 when the British scientific journal Nature published letters by the Englishmen Henry Faulds and William James Herschel describing the uniqueness and permanence of fingerprints. Their observations were verified by the English scientist Sir Francis Galton, who designed the first elementary system for classifying fingerprints based on grouping the patterns into arches, loops, and whorls. Galtons system was improved upon by London police commissioner, Sir Edward R. Henry. The Galton-Henry system of fingerprint classification was published in June 1900, and officially introduced at Scotland Yard in 1901. It is the most widely used method of fingerprinting to date. Police Cars In 1899, the first police car was used in Akron, Ohio. Police cars became the basis of police transportation in the 20th century. Timeline 1850s The first multi-shot pistol, introduced by Samuel Colt, goes into mass production. The weapon is adopted by the Texas Rangers and, thereafter, by police departments nationwide. 1854 to 59 San Francisco is the site of one of the earliest uses of systematic photography for criminal identification. 1862 On June 17, 1862, inventor W. V. Adams patented handcuffs that used adjustable ratchets - the first modern handcuffs. 1877 The use of the telegraph by fire and police departments begins in Albany, New York in 1877. 1878 The telephone comes into use in police precinct houses in Washington, D.C. 1888 Chicago is the first U.S. city to adopt the Bertillon system of identification. Alphonse Bertillon, a French criminologist, applies techniques of human body measurement used in anthropological classification to the identification of criminals. His system remains in vogue in North America and Europe until it is replaced at the turn of the century by the fingerprint method of identification. 1901 Scotland Yard adopts a fingerprint classification system devised by Sir Edward Richard Henry. Subsequent fingerprint classification systems are generally extensions of Henrys system. 1910 Edmund Locard establishes the first police department crime laboratory in Lyon, France. 1923 The Los Angeles Police Department establishes the first police department crime laboratory in the United States. 1923 The use of the teletype is inaugurated by the Pennsylvania State Police. 1928 Detroit police begin using the one-way radio. 1934 Boston Police begin using the two-way radio. 1930s American police begin the widespread use of the automobile. 1930 The prototype of the present-day polygraph is developed for use in police stations. 1932 The FBI inaugurates its crime laboratory which, over the years, comes to be world-renowned. 1948 Radar is introduced to traffic law enforcement. 1948 The American Academy of Forensic Sciences (AAFS) meets for the first time. 1955 The New Orleans Police Department installs an electronic data processing machine, possibly the first department in the country to do so. The machine is not a computer, but a vacuum-tube operated calculator with a punch-card sorter and collator. It summarizes arrests and warrants. 1958 A former marine invents the side-handle baton, a baton with a handle attached at a 90-degree angle near the gripping end. Its versatility and effectiveness eventually make the side-handle baton standard issue in many U.S. police agencies.

Dendrochronology - Tree Ring Records of Climate Change

Dendrochronology - Tree Ring Records of Climate Change Dendrochronology is the formal term for tree-ring dating, the science that uses the growth rings of trees as a detailed record of climatic change in a region, as well as a way to approximate the date of construction for wooden objects of many types. Key Takeaways: Dendrochronology Dendrochronology, or tree-ring dating, is the study of growth rings in deciduous trees to identify absolute dates of wooden objects.  Tree rings are created by the tree as it grows in girth, and the width of a given tree ring is dependent on climate, so a stand of trees will all have a near-identical pattern of tree rings.The method was invented in the 1920s by astronomer Andrew Ellicott Douglass and archaeologist Clark Wissler.  Recent applications include tracking climate change, identifying pending slope collapses, finding American trees in World War I trench construction, and using chemical signatures in tropical trees to identify past temperature and precipitation.  Tree ring dating is also used to calibrate radiocarbon dates. As archaeological dating techniques go, dendrochronology is extremely precise: if the growth rings in a wooden object are preserved and can be tied into an existing chronology, researchers can determine the precise calendar year- and often season- the tree was cut down to make it. Because of that precision, dendrochronology is used to calibrate ​radiocarbon dating, by giving science a measure of the atmospheric conditions which are known to cause radiocarbon dates to vary. Radiocarbon dates which have been calibrated by comparison to dendrochronological records are designated by abbreviations such as cal BP, or calibrated years before the present. What are Tree Rings? Cross section of a tree illustrating the cambium layer. Lukaves / iStock / Getty Images Tree-ring dating works because a tree grows larger- not just height but gains girth- in measurable rings each year in its lifetime. The rings are the cambium layer, a ring of cells that lies between the wood and bark and from which new bark and wood cells originate; each year a new cambium is created leaving the previous one in place. How large the cambiums cells grow in each year, measured as the width of each ring, depends on temperature and moisture- how warm or cool, dry or wet each years seasons were. Environmental inputs into the cambium are primarily regional climatic variations, changes in temperature, aridity, and soil chemistry, which together are encoded as variations in the width of a particular ring, in the wood density or structure, and/or in the chemical composition of the cell walls. At its most basic, during dry years the cambiums cells are smaller and thus the layer is thinner than during wet years. Tree Species Matters Not all trees can be measured or used without additional analytical techniques: not all trees have cambiums that are created annually. In tropical regions, for example, annual growth rings are not systematically formed, or growth rings are not tied to years, or there are no rings at all. Evergreen cambiums are commonly irregular and not formed annually. Trees in arctic, sub-arctic and alpine regions respond differently depending on how old the tree is- older trees have reduced water efficiency which results in a reduced response to temperature changes. Invention of Dendrochronology Tree-ring dating was one of the first absolute dating methods developed for archaeology, and it was invented by astronomer Andrew Ellicott Douglass and archaeologist Clark Wissler in the first decades of the 20th century. Douglass was mostly interested in the history of climatic variations exhibited in tree rings; it was Wissler who suggested using the technique to identify when adobe pueblos of the American southwest were built, and their joint work culminated in research at the Ancestral Pueblo town of Showlow, near the modern town of Showlow, Arizona, in 1929. The Beam Expeditions Archaeologist Neil M. Judd is credited with convincing the National Geographic Society to establish the First Beam Expedition, in which log sections from occupied pueblos, mission churches and prehistoric ruins from the American southwest were collected and recorded alongside those from living ponderosa pine trees. The ring widths were matched and cross-dated, and by the 1920s, chronologies were built back nearly 600 years. The first ruin tied to a specific calendar date was Kawaikuh in the Jeddito area, built in the 15th century; charcoal from Kawaikuh was the first charcoal used in (the later) radiocarbon studies. In 1929, Showlow was being excavated by Lyndon L. Hargrave and Emil W. Haury, and dendrochronology conducted on Showlow eventuated the first single chronology for the southwest, extending over a period of over 1,200 years. The Laboratory of Tree-Ring Research was established by Douglass at the University of Arizona in 1937, and it is still conducting research today. Building a Sequence Over the past hundred years or so, tree ring sequences have been built for various species all over the world, with such long date strings as a 12,460-year sequence in central Europe completed on oak trees by the Hohenheim Laboratory, and an 8,700 year-long bristlecone pine sequence in California. Building a chronology of climate change in a region today was first simply a matter of matching overlapping tree ring patterns in older and older trees; but such efforts are no longer based solely on tree-ring widths. Features such as wood density, the elemental composition (called dendrochemistry) of its makeup, the anatomical features of the wood, and stable isotopes captured within its cells have been used in conjunction with traditional tree ring width analysis to study air pollution effects, the uptake of ozone, and changes in soil acidity over time. Medieval Là ¼beck In 2007, German wood scientist Dieter Eckstein described wooden artifacts and building rafters within the Medieval town of Là ¼beck, Germany, an excellent example of the myriad ways the technique can be used. Là ¼becks medieval history includes several events that are pertinent to the study of tree rings and forests, including laws passed in the late 12th and early 13th century establishing some basic sustainability rules, two devastating fires in 1251 and 1276, and a population crash between about 1340 and 1430 resulting from the Black Death. Construction booms at Là ¼beck are marked by the extensive use of younger trees, which signal demand outpacing the ability of the forests to recover; busts, such as after the Black Death decimated the population, are denoted by a long period of no construction at all, followed by the use of very old trees.In some of the wealthier houses, the rafters used during construction were cut down at different times, some spanning more than a year; most other houses have rafters cut down at the same time. Eckstein suggests that is because wood for the wealthier house was obtained at a timber market, where the trees would have been cut and stored until they could be sold; while less well-off house constructions were built just-in-time.Evidence of long-distance timber trade is seen in wood imported for pieces of art such as the Triumphal Cross and Screen at the St. Jacobi Cathedral. That was identified as having been constructed out of wood that had been specifically shipped in from 200-300-yea r-old trees from the Polish-Baltic forests, probably along established trade routes from Gdansk, Riga, or Konigsberg harbors. Tropical and Subtropical Environments Cludia Fontana and colleagues (2018) documented advances in filling a major gap in dendrochronological research in tropical and subtropical regions, because trees in those climates have either complex ring patterns or no visible tree rings at all.  That is an issue because because since global climate change is in progress, we need to understand the physical, chemical and biological processes that effeect terrestrial carbon levels is increasingly important. The tropic and subtropic regions of the world, such as the Brazilian Atlantic Forest of South America, store about 54% of the total biomass of the planet. The best results for standard dendrochronological research are with the evergreen Araucaria angustifolia (Paran pine, Brazilian pine or candelabra tree), with a sequence established in the rainforest between 1790–2009 CE); preliminary studies (Nakai et al. 2018) have shown that there are chemical signals which trace precipitation and temperature changes, which may be le veraged for gaining more information.    The elliptical rings on this tree from Turkey show that the tree grew tilted on a slope for several years, the part facing the upslope identified by the narrowness of the ring in the right hand side of the image. Mehmet Gà ¶khan Bayhan / iStock / Getty Images A 2019 study (Wistuba and colleagues) found that tree rings can also warn of impending slope collapses. It turns out that trees that are tilted by landsliding record eccentric elliptical tree rings. The downslope parts of the rings grow wider than the upslope ones, and in studies carried out in Poland, Malgorzata Wistuba and colleagues found that those tilts are in evidence between three and fifteen years prior to catastrophic collapse. Other Applications It had long been known that three 9th century Viking period boat-grave mounds near Oslo, Norway (Gokstad, Oseberg, and Tune) had been broken into at some point in antiquity. The interlopers defaced the ships, damaged the grave goods and pulled out and dispersed the bones of the deceased. Fortunately for us, the looters left behind the tools they used to break into the mounds, wooden spades and stretchers (small handled platforms used to carry objects out of the tombs), which were analyzed using dendrochronology. Tying tree ring fragments in the tools to established chronologies, Bill and Daly (2012) discovered that all three of the mounds were opened and the grave goods damaged during the 10th century, likely as part of Harald Bluetooths campaign to convert Scandinavians to Christianity. Wang and Zhao used dendrochronology to look at the dates of one of the Silk Road routes used during the Qin-Han period called the Qinghai Route. To resolve conflicting evidence over when the route was abandoned, Wang and Zhao looked at wood remains from tombs along the route. Some historical sources had reported the Qinghai route was abandoned by the 6th century AD: dendrochronological analysis of 14 tombs along the route identified a continuing use through the late 8th century. A study by Kristof Haneca and colleagues (2018) described evidence for the importation of American timber to construct and maintain the 440 mi (700 km) long defensive line of World War I trenches along the western front.

Government regulation of business Essay Example | Topics and Well Written Essays - 250 words

Government regulation of business - Essay Example The reason for this argument is that government regulation sets a very fair business operating ground for all businesses to operate. Kain (2013) will however not support this opinion, saying that the regulations often foster the need for rigorous competition between companies, resulting in the untimely collapse of smaller businesses. Generalizing the ideas gathered above, Holt (2013) expresses the opinion that there are generally five (5) major areas of government regulations and the perspective from which a particular business takes the regulation determines the effect that these would have on their operations. The five government regulations identified by Holt (2013) are in the areas of advertisement, employment and labor, environmental, privacy, and safety and health issues. Based on the five major areas of government regulations outlined by Holt (2013), the Best Practice website (2013) indicates that the absence of any of the key government regulatory indicators would lead to serious market failures in the areas of â€Å"insufficient information for the public, injustice to customers, Failure to comply with State and Firm Regulations, unjust compensation, and Unaffordability increases†.

International Institute of Finance Essay Example | Topics and Well Written Essays - 2000 words

International Institute of Finance - Essay Example IIF has a robust Knowledge space in the form of its website which is used to provide above packaged knowledge in part of full to public and members. Knowledge events include briefings, meetings, seminars, conferences, workshops, staff visits to information sites, collaborative efforts to bring together global financial lenders, etc. Firstly, CRM can help IIF to handle the increase in its membership base (from 150 in 1996 to 20,000 in 2001). CRM will handle list of members with appropriate information, such as contacts, areas of interests, history and other related information. So IIF can create groups and subgroups of members, classify them by various parameters, send them adequate promotion information, and notify them about potentially interesting events. Although IIF does not have revenue goals, all these improvements will raise quality of services, members' satisfaction and loyalty and facilitate work of staff of IIF. Secondly, CRM can provide staff and members of IIF access outside of the office that increases flexibility and mobility for both staff and members. It is true that top managers of banking and financial institutions travel a lot, so access to IIF knowledge base via Internet from anywhere on Earth will be very useful for them. ThThirdly, CRM will provide ground for interaction of members with potential members, for example, via newsletters, online discussions, publications, meetings and other forms of communications. So marketing to potential members will be supported. The proposed CRM is much better then Access database, what IIF is currently using. To begin with, use of Access was limited to IIF premises; its traveling staff could not access it in travel. Also, it had limited versatility in that it abruptly aborted when accessed by more than five users simultaneously. Then, membership-billing system was separate and membership department sent bills manually to members. Similarly events department had to collect events' registration details from IIF website and re-key it in the Access database system. So Access database does not meet current needs of IIF. The new CRM must meet management's strategic objective to have robust activities even with incredibly increased client base and offer members a comprehensive user interface. More importantly, the management wanted an integrated view of CRM, billing, accounting and events management alongside making its databases accessible to mobile staffers and public-members or non-members. The new CRM included not only all of the above in its design but also had the capability to handle increased staffers' research efforts warranted by dynamic economic scenarios in emerging markets. The value of designing the system with an open architecture Before talking about open architecture, I would like to mention that an architecture-first approach would really help in the situation. An early focus on the architecture results in a solid foundation for the 20% of the stuff (requirements, components, use cases and risks) that drives the overall success of the project. Getting the architecturally important components to be well understood and stable before worrying about the complete set of different features should make

Manifestation of human culture Essay Example for Free

Manifestation of human culture Essay This statement provides for us the conjoining philosophy of Joseph Gobineau and Adolf Hitler. These men firmly believed that anything that was wrong with the world in general, and their societies or governments in particular could be traced directly to the infusion of other race types with the Aryan race. In his book, The Inequality of Human Races, Gobineau sets out in the fourth chapter to show that the degeneration of the blood or race of a group of people who found a government or society is the reason why that government or society will fail. He does not fully reject the philosophy of his ancestors that certain things like lawlessness and irreligion play a part in the fall of the society, but he teaches that the greater issue is the degenerative effects that intermingling of race types has on the main societal people.

Adultery in Great Gatsby & Scarlet Letter Essay -- F. Scott Fitzgerald

  Ã‚  Ã‚  Ã‚  Ã‚  The Scarlet Letter by Nathaniel Hawthorne and The Great Gatsby by F. Scott Fitzgerald are two novels, which address similar themes with completely opposite resolves. The authors use their main characters, Hester, Dimmesdale, Gatsby, and Daisy, in their respective works to present these themes. The action in both novels revolves around unfaithfulness, its effects on the characters, and the results of committing adultery, which prove to be antipode from one novel to the other. These antitheses can be found by a look at the different roles of adultery in the novels.   Ã‚  Ã‚  Ã‚  Ã‚  One major theme found in both novels and addressed in different ways is adultery. Unfaithfulness is ever present in The Great Gatsby, while it is a one-time occurrence in The Scarlet Letter. It would appear that this would make adultery a more powerful force in The Great Gatsby. On the contrary, it is seen as insignificant in Fitzgerald’s novel and definitive in The Scarlet Letter. Whether it is Tom and Myrtle, or Gatsby and Daisy, the fact that these people are wed appears irrelevant to them. Meanwhile, Hester and Dimmesdale have sex as part of a meaningful relationship, but are persecuted for it. These varying reactions are caused partially by the extreme contrast of environment between the two novels. Another factor is the different degrees of conscientiousness and its importance between the novels. Hester and Dimmesdale repent and seek forgiveness for their sins. They use their experience to make ...

In the Sun Also Rises by Ernest Hemingway Essay

In the Sun Also Rises, by Ernest Hemingway, alcoholism is an important theme in the novel. Alcoholism is a large part of Ernest Hemingway’s novel â€Å"The Sun Also Rises†. Drinking is the greatest escape that the characters use and the author employs it very often in the novel. All throughout the novel, the characters are drinking excessively. They use drinking to also help prove themselves. Because of Jake’s war wound made him physically unable, he feels that he must prove himself to people so he uses drinking to prove himself. Jake also uses wine to forget the things that he doesn’t like about his friends such as the fight between Mick and Cohn, when Mike was mad that Cohn is always looking at Brett and holding in to her everywhere she goes. â€Å"There was much wine and ignored tension, and a feeling of things coming that you could not prevent happening. Under the wine I lost the disgusted feeling and was happy. It seemed that they were all such nice people† (Hemingway 150). In reality, all that drinking does is to give them something in common so that they can relate to one another in some parts of their lives. They are always drinking together and talking about their life difficulties. Often, drinking provides a way of escaping reality and allows them to avoid their problems by avoid thinking about them. In conclusion, in Hemingway’s the Sun Also Rises, it is clear that alcohol dependency is a main theme.

Importance of traveling

Have you ever wondered why traveling is so important? Most amount of people around the word think that traveling is a waste of time and money. To me traveling is important , because traveling is a way to get more knowledge about traditions and religions from different countries.

Buo Doi Video Report essays

Buo Doi Video Report essays To understand who Ricky was and what he became you have to look at what he was exposed to and what he went through starting at a very young age. As a child in Vietnam he had no childhood as he worked selling bread on the streets to help his family. The abandoned childhood made him angry as he watched the school children his age play while he had to work. He experienced violence at a young age specifically death when while washing his hands in the river he noticed a dead body floating near him. He commented that he accepted this to be not unusual but just the way things were in Vietnam. In his familys attempt and eventual success in escaping Vietnam he was victimized in the refugee camp before he made it to America. Arriving in the United States alone (literally) without his family he could not believe what he saw, a whole new world as he describes it. This new world fascinated him and he wanted to be a part of immediately and his life of abandonment and being alone would soon change dramatically. As he entered High School he started to experience what it was like to be a minority in the U.S. The other students at school begin to call him names and he experienced the racial bias that make up American society. The further he withdrew from the name calling gook, nip and the more isolated he became, ultimately he drew closer to those like him. He found new friends, friends who spoke his language, understood him, could relate to him; he was no longer alone. Within these friends Ricky felt accepted, wanted and he felt like he belonged. They would share their life experiences, stories, likes, and dislikes all of the things that brought them together. He had a family a family from the heart as he wou ld say. In reality Ricky had a gang and that gang was his family now. Through the gang Ricky found he could get what he wa ...

A Brief History of Plasma Television

A Brief History of Plasma Television The very first prototype for a plasma display monitor was invented in July 1964 at the University of Illinois by professors Donald Bitzer and Gene Slottow, and then graduate student Robert Willson. However, it was not until after the advent of digital and other technologies that successful plasma televisions became possible. According to Wikipedia a plasma display is an emissive flat panel display where light is created by phosphors excited by a plasma discharge between two flat panels of glass. During the early sixties, the University of Illinois used regular televisions as computer monitors for their in-house computer network. Donald Bitzer, Gene Slottow, and Robert Willson (the inventors listed on the plasma display patent) researched plasma displays as an alternative to the cathode ray tube-based televisions sets being used. A cathode-ray display has to constantly refresh, which is okay for video and broadcasts but bad for displaying computer graphics. Donald Bitzer began the project and enlisted the help of Gene Slottow and Robert Willson. By July of 1964, the team had built the first plasma display panel with one single cell. Todays plasma televisions use millions of cells. After 1964, television broadcast companies considered developing plasma television as an alternative to televisions using cathode ray tubes. However, LCD or liquid crystal displays made possible flat screen television that squelched the further commercial development of plasma display. It took many years for plasma televisions to became successful and they finally did due to the efforts of Larry Weber. University of Illinois author Jamie Hutchinson wrote that Larry Webers prototype sixty-inch plasma display, developed for Matsushita and bearing the Panasonic label, combined the size and resolution necessary for HDTV with the addition of thinness.

Psychoanalytic Film Theory Essay Example | Topics and Well Written Essays - 2250 words

Psychoanalytic Film Theory - Essay Example Mulvey's essay can be asserted as a historical document, due to her examinations of the pleasurable and controlling dimensions of â€Å"vision† that several disciplines studied before her and extended after her work. She argued that the â€Å"unconscious† of the patriarchal system has projected itself unto the film narrative. The male gaze had perilously affected the discourse between the dominant and dominated sectors of society, where political binaries of man/woman and active/passive are present. This paper will discuss the reasons why feminist film scholars adopted psychoanalytic film theory. It will also use feminist psychoanalytic spectatorship theory in studying Hitchcock’s Rear Window (1959). Feminist scholars adopted the psychoanalytic film theory, because the latter aims to examine and depict gender identity using cultural, instead of biological, concepts that are present in films, so that the exclusion of women in dominant film discourses can be identified and dismantled for purposes of political empowerment by breaking the domination of the male gaze and reversing spectatorship from male to female gazing. Rear Window (1959) depicts scopophilia through sexual stimulations of visual pleasures and narcissism, and its pervasive use of the sexual objectification of women, where the film sees them as sources of both pleasure and pleasure. Feminist film scholars, during the 1970s, were interested in analyzing the diverse forms of gender oppression that relegated them to a â€Å"secondary† social and political status (Kaplan 1238). Their takeoff was the â€Å"cultural,† and not the biological, aspect of negative female experiences, where cultural semiotic systems present relationships in how women are seen and consumed in films and in societies where they live in. These scholars noted that the â€Å"objectification† of women, which limited their desires and objectives, could be the root cause of their oppressed conditions in real and reel life.
