Genotype and testcross; Drosophila

In your experiments with Drosophila, you found that the wildtype allele that codes for grey adult insects is sometimes mutated, with mutants having a black colour. Similarly, you find that your population has alleles that code for vestigial wings instead of the wildtype normal wings. (Both mutations are recessive.) You want to know whether the two genes for body colour and wings are linked. In your preliminary crosses you have established a large number of individuals that you require for testcrosses.

9a. Which two genotypes will you use for the testcross? (Hint: One of the two genotypes should be a heterozygous dihybrid.) Use the common wildtype notation (e.g., “ar+ tg”) rather than the allele notation (VvZZ). For simplification, disregard the gender. (2)

9b. Indicate the two phenotypes of your testcross. (1)

9c. Indicate the genotypes of the progeny (next generation) of the testcross by drawing a Punnett square. (3)

Assuming a total number of 4400 flies for the progeny generation, what are your expectations for the ratio of genotypes if 

9d. the two genes are linked? (1)

9e. the two genes are not linked? (1)

9f.  Finally, if the two genes are not linked according to your results, would you expect that they lie on different chromosomes? Explain your answer. (2)

Please answer the questions for me. I need this back by Sunday

ACEs  or adverse childhood experiences are potentially traumatic things that  occur in a child’s life. These experiences occur before a child is  eighteen, but they remember them throughout their life. ACEs refer to  specific types of trauma children may experience. They  include physical, sexual, and emotional abuse; neglect, losing a parent  such as through divorce, being exposed to domestic violence, having a  parent with a mental illness, having a member of the household who  abuses drugs or alcohol, and having a parent who has been in jail. Children  living through these experiences may suffer from adverse effects for  the rest of their lives. Watch Dr. Nadine Burke Harris’s TedTalk

Contextualizing Graffiti: An Analysis of Urban Expression

Graffiti is common in many locations worldwide and is frequently regarded as a contentious form of urban expression. The specific graffiti in question offers a fascinating topic for examination because it is depicted in a vivid, disorganized mixture of colors and symbols on a concrete wall in a metropolitan underpass. It begs the question: were the graffiti artists, gang members, or just random people vandalizing property responsible for this? We can try to identify the origin of the graffiti by looking at its features and comparing them with information on gang and tagger activity that is currently known.

Characteristics of the Graffiti

A huge, stylized signature or “tag,” a string of numerals, and a variety of abstract designs are some of the standout elements of the graffiti that is the subject of this analysis. The tag, which is the most noticeable element, is composed of large, connected letters with angular edges and pronounced curves. The tag stands out from the background thanks to the vivid color scheme and the use of contrasting hues. Smaller, less readable marks and symbols that appear to be randomly distributed surround the tag.

Gang Graffiti or Tagging?

It’s critical to comprehend the differences between gang members and taggers in order to evaluate whether this graffiti is their own. Gang graffiti, sometimes referred to as “gangbanging,” is frequently used to demarcate areas, communicate with other gangs, or show support for a particular gang (Phillips, 1999). This kind of graffiti usually contains the name of the gang, numerals, or other symbols linked to the group, and occasionally taunts or threats aimed at competitors. Since communication rather than artistic expression is its primary goal, it is typically simple and devoid of artistic decoration (Ley & Cybriwsky, 1974). However, the main goals of tagging are self-expression and gaining notoriety among other graffiti artists. Taggers, sometimes called “writers,” frequently look for extremely visible spots in an effort to get as many people to view their tags as possible. The employment of a distinctive pseudonym, or “tag,” that is styled and used repeatedly in different contexts, is what defines tagging. The aforementioned graffiti appears to have more in common with the traits of tagging than with gang activities. The concentration on a big, stylised tag implies that the artist was trying to make a name for themselves and make a statement in the city. In contrast to typical gang graffiti, which often serves a utilitarian purpose, the abstract designs and vivid colors suggest an artistic aim (Phillips, 1999). Furthermore, it is less likely that gang members created this graffiti because it lacks obvious gang emblems, numbers, or threatening statements.

Defacing Property or Artistic Expression?

Even though some could contend that all graffiti is a type of property defacement, it’s important to distinguish between intentional, artistic expression and mindless vandalism. As evidenced by this graffiti, tagging can be considered an urban art form, even though it doesn’t follow the rules of legality (Ferrell, 1996). Taggers frequently take tremendous pride in what they do, devoting a lot of time to honing their tags and creating a distinctive look that makes them stand out from the competition.It is also true, though, that this kind of expression takes place without the owners’ permission, which is why it is considered vandalism. This conflict between property rights and art is typically at the center of the ethical discussion around graffiti. In this instance, although some may view the graffiti as defacing property, it also exemplifies a subcultural art form that questions accepted ideas of public space and ownership (Macdonald, 2002).

Conclusion

The analysis of the graffiti indicates that the creator of this piece was probably a tagger rather than a member of a gang or someone who was just vandalizing property. The focus on aesthetic flair, the unique tag, and the lack of symbols associated with gangs imply that the graffiti is an instance of tagging, or self-expression within the graffiti subculture. While the controversy over graffiti’s legitimacy as art continues, it is evident that this specific piece is more than just an act of vandalism; it is a statement of identity and presence in the urban environment.

The purpose of this paper is to understand the experience of human resource (HR) professionals in managing career development for older workers.

The gap in the previous research was that there was very little research on career development in older workers in the workplace. Many organizations don’t provide career development support for older workers. Previous research on older workers looked at things like ineffective training, attitudes about older workers, the desirability of longer working lives in the workplace, and organizational change practices. None of the previous research has focused on the design and implementation of career development for older workers.

Research implications: Very little research on HR professionals has focused on their experiences through a qualitative lens. The personal identity of HR professionals as older workers themselves demonstrated the “trickle down” effect of innovative career development practices for older workers.

Practical implications: Organizations need to address bias against older workers. Often, organizations see the value in older workers but that does not translate into career development practices—perhaps as a result of subconscious ageism.

Limitations: The study was conducted at three large organizations in Australia limiting the application of the findings to smaller organizations or other nations. The experiences of HR professionals in those settings may be very different.

Informed consent to participate in audio-recorded interview. Participant anonymity. Pseudonyms used and no identifying information was included in the study.

More qualitative research focusing on HR professionals’ experiences could result in a benefit to older workers for career development. The development of career development models for older workers is another potential area for future research. Finally, exploring workplace culture and the way organizations value older workers is important for further study given the increased time many will spend in the workplace well into later life.

Week 1 – Scenario

Presentation: 65-year-old woman with a loss of appetite, abdominal cramps, constipation, and blood in her stool.

History: Delores Murphy, a 65-year-old white female, was in good health until about 6 weeks ago, when she noted occasional cramps in the left lower quadrant of the abdomen associated with constipation. The episodes of cramping last about 30 minutes each and are most severe in the hour following her meals. She has taken laxatives which have partially relieved her symptoms, but she has had a decreased appetite and 12-pound weight loss over the past four weeks. In addition, she has become increasingly fatigued over this period. When questioned about her bowel habits, she reported bright red blood in her stools and a smaller caliber (i.e., diameter) of stool over the past two weeks.

Physical Examination: She appeared fatigued and distressed. Head and neck exams were normal, as was her thorax. Palpation of the abdomen revealed a 10 x 10 cm mass and tenderness in the left lower quadrant. Percussion over this area revealed a hollow, tympanic sound. Hepatomegaly was noted, and a hard and slightly tender liver edge was felt in the right upper quadrant. Bowel sounds were noticeably reduced. A stool sample was tested with Guaiac paper and was positive for blood.

Questions:  
Choose 
one of the three sets of questions to serve as your initial response. 

1. Propose an explanation for Delores’s abdominal cramps and left lower quadrant mass.

2. Propose an explanation for Delores’s reduced bowel sounds and smaller-caliber stools.

3. What is “flexible sigmoidoscopy”?

OR

1. How is an “air-contrast barium enema” performed?

2. Propose an explanation for Delores’s weight loss and decreased appetite.

3. How would the appearance of an adenoma differ from that of a carcinoma under the microscope?

OR

1. Why was it important to biopsy suspicious lesions?

2. What kinds of information can be gained by performing an air-contrast barium enema?

3. Ninety percent of all cancers are carcinomas. Propose an explanation for why such a disproportionately high number of cancers are carcinomas.

Biology week 2 assignment

Following the attack on the World Trade Center and the Pentagon in September 2001, President George W. Bush declared war on terrorism and put countries who harbor terrorists on notice that America would go after terrorists wherever they may be found (see 
President Bush’s address to CongressLinks to an external site.). This series of events fundamentally changed how Americans and lawmakers conceptualized terrorism. Terrorism shifted from strictly a criminal justice issue to a military issue. Since then, America has taken a dual-pronged approach, using the military to counter terrorism overseas and law enforcement and Homeland Security apparatus to bring terrorists to justice. As a result, Homeland Security personnel find themselves connecting with various U.S. and international entities to deconflict work, share information, and share resources.

For this assignment, you will assume the role of an Assistant Special Agent in Charge for the Department of Homeland Security’s Office of Inspector General (OIG). Your supervisor, the Special Agent in Charge of Headquarters Operations, is attending two meetings to help her decide where to commit a full-time Special Agent. The Agent will still be a Special Agent for DHS OIG, but they will be permanently assigned to either the FBI National Joint Terrorism Task Force or INTERPOL Washington, D.C.

The agent, whom you will supervise, will be a conduit for information back to your agency. They will also need to provide DHS OIG special agents with access to various databases and resources at either the FBI or INTERPOL. As the supervisor over the agent, you have been asked to provide a PowerPoint presentation to your supervisor covering several topics that will (A) demonstrate your knowledge of the issues involved and (B) help you and your supervisor understand the backdrop the issues and the bigger picture context related to terrorism and the international stage. This is particularly important because the agent chosen to work at either INTERPOL or the FBI will be heavily immersed in counterterrorism and international relations.

In your A Tale of Two Meetings PowerPoint,

· Describe the constitutional issues that must be addressed to “declare war on terrorism.”

· Compare and contrast the counterterrorism policies of the European Union and the United Nations with the DHS Strategic Goal: Counter Terrorism and Homeland Security Threats.

· Discuss whether Western society is stronger and more secure by having one consistent program or by having different programs with similarities and differences.

· Summarize the mission of the DHS OIG Office of Investigations.

· Explain the potential for a nexus between DHS OIG investigative activity and INTERPOL. Would joint activities between DHS OIG and INTERPOL be of any value to the two entities? If so, how would these joint activities add value?

· Explain the potential for a nexus between DHS OIG investigative activity and FBI JTTF. Would joint activities between DHS OIG and FBI JTTF be of any value to the two entities? If so, how would these joint activities add value?

· Determine which entity the Agent should be assigned to based on your final assessment.
