The popularity of shows like CSI has led to widespread misperceptions about the quality and nature of forensic science. As you point out, the CSI effect could lead to wrongful acquittals, but it is equally possible that jurors might wrongfully convict based … unconscious tendencies that jurors can develop after watching many episodes of CSI shows and believing that the crime scene investigation process and forensic science methods work the same way in real life as on television.

There are certainly similarities, and many of the television depictions can help jurors to better understand what to expect from forensic science. On the other hand, jurors can cultivate unrealistic expectations of what forensic science can offer and how the evidence can and should be interpreted.

...Science Sickle cell anemia is among the highly prevalent diseases in the contemporary society. Sickle cell anemia is a disorder of the blood that is caused by the inheritance of the gene that alters the shape of the sickle cell. Therefore, the gene interferes with the working of hemoglobin in the movement of oxygen. The prevalence of the sickle cell anemia varies regarding the geographical position and the ethnic identity. In the United States, the sickle cell anemia is most prevalent among African Americans. The disease also shows a relatively higher prevalence of the disease in the Hispanics followed by the Whites. However, the prevalence also varies from one place to another in the United States (Lervolino et al. 2011).
Sickle cell anemia is a cancerous disease making it difficult to treat. However, various trends are involved in the diagnosis of the disease. The diagnosis of the disease involves a blood……

...Science How to Rid Oneself of Diabetes through Healthy Dieting
Concrete Experience
I started my health and nutrition program study after I began reading more health literature. I had seen my father’s health erode as a result of poor dieting and lack of exercise. He suffers from diabetes and is convinced it is not related to his lack of dieting or exercise, but the literature I had read convinced me otherwise. Davis (2008) showed that natives in the Marshall Islands developed diabetes when they moved away from their natural, organic diets and began consuming pre-packaged, fast foods. He initiated a program that returned them to a lifestyle of living off the land and sea, which gave them exercise and a healthy, organic diet. Their diabetes disappeared (Davis, 2008). Bray, Nielsen and Popkin (2004) and Malik et al. (2010) also have shown a link between consumption of high-fructose corn syrup, soda pop……

Fake News Detection

Pages: 4 (1291 words) Sources: 5 Document Type:literature review Document #:42567912

...Science Fake News Detection
How can fake news be detected and prevented from dominating the online discourse of news events? Numerous researchers have been discussing this issue and identifying ways to detect fake news, whether on social media (Shu et al.) or by creating a benchmark dataset to facilitate the process (Wang). The topic of this study is fake news detection and what methods are available in this new field. The reason for addressing this topic is that fake news has been a hot button issue in politics ever since the election of Donald Trump. Understanding how fake new proliferates and what can be done to stop its proliferation is something that the digital community can benefit from. The inquiry question for this review is: What are some of the ways that fake news detection can be facilitated?
This literature is organized according to what the researchers have found.……
