Do multiple true-false items beat the commonly used one-best-answers questions regarding to the Ottawa Criteria for Good Assessment? Results of a literature review

Background: Multiple True-False-Items (MTF-Items) might offer some advantages compared to one-best-answer-questions (TypeA) as they allow more than one correct answer and may better represent clinical decisions. However, in medical education assessment MTF-Items are seldom used. Summary of Work: With this literature review existing findings on MTF-items and on TypeA were compared along the Ottawa Criteria for Good Assessment, i.e. (1) reproducibility, (2) feasibility, (3) validity, (4) acceptance, (5) educational effect, (6) catalytic effects, and (7) equivalence. We conducted a literature research on ERIC and Google Scholar including papers from the years 1935 to 2014. We used the search terms “multiple true-false”, “true-false”, “true/false”, and “Kprim” combined with “exam”, “test”, and “assessment”. Summary of Results: We included 29 out of 33 studies. Four of them were carried out in the medical field Compared to TypeA, MTF-Items are associated with (1) higher reproducibility (2) lower feasibility (3) similar validity (4) higher acceptance (5) higher educational effect (6) no studies on catalytic effects or (7) equivalence. Discussion and Conclusions: While studies show overall good characteristics of MTF items according to the Ottawa criteria, this type of question seems to be rather seldom used. One reason might be the reported lower feasibility. Overall the literature base is still weak. Furthermore, only 14 % of literature is from the medical domain. Further studies to better understand the characteristics of MTF-Items in the medical domain are warranted. Take-home messages: Overall the literature base is weak and therefore further studies are needed. Existing studies show that: MTF-Items show higher reliability, acceptance and educational effect; MTF-Items are more difficult to produce

Improving residency training with the help of multisource feedback: Generation of a model of influencing factors

Background: Feedback is considered to be one of the most important drivers of learning. One form of structured feedback used in medical settings is multisource feedback (MSF). This feedback technique provides the opportunity to gain a differentiated view on a doctor’s performance from several perspectives using a questionnaire and a facilitating conversation, in which learning goals are formulated. While many studies have been conducted on the validity, reliability and feasibility of the instrument, little is known about the impact of factors that might influence the effects of MSF on clinical performance. Summary of Work: To study under which circumstances MSF is most effective, we performed a literature review on Google Scholar with focus on MSF and feedback in general. Main key-words were: MSF, multi-source-feedback, multi source feedback, and feedback each combined with influencing/ hindering/ facilitating factors, effective, effectiveness, doctors-intraining, and surgery. Summary of Results: Based on the literature, we developed a preliminary model of facilitating factors. This model includes five main factors influencing MSF: questionnaire, doctor-in-training, group of raters, facilitating supervisor, and facilitating conversation. Discussion and Conclusions: Especially the following points that might influence MSF have not yet been sufficiently studied: facilitating conversation with the supervisor, individual aspects of doctors-in-training, and the causal relations between influencing factors. Overall there are only very few studies focusing on the impact of MSF on actual and long-term performance. We developed a preliminary model of hindering and facilitating factors on MSF. Further studies are needed to better understand under which circumstances MSF is most effective. Take-home messages: The preliminary model might help to guide further studies on how to implement MSF to use it at its full potential.

The Process of Starting a Business

Many students are inspired to start their own business venture after taking some courses in school or simply just taking an idea and turning it into a business. The beginning process is usually most difficult in terms of establishing a functioning business, getting the right connections, and avoiding discouragement to follow through with the business. That is why many businesses fall into the categories of starting, failing along the process, or failing to get started. There is a lot to be learned from the process of starting a business venture. In addressing this issue, some of the questions this research study aims to explore and study are how people go about their new venture efforts? Second, what steps they undertake? Third, from whom do they get information? And fourth, how do they use that information? This study will seek a variety of insights that can help answer these questions and improve our understanding of why some businesses fail, succeed, or never get started.

The Effects of a Physical Activity Intervention on the way Elementary School Girls Play

The rates of childhood and adolescent obesity in the United States have been increasing steadily. American youth continue to eat more (increase energy intake) and reduce physical activity (decrease energy expenditure) resulting in increased body weight and body fatness. One way to help reduce body weight in children is to increase physical activity. The purpose of this study was to determine if an age appropriate before-school physical activity intervention would be successful in increasing energy expenditure, intensity of activity, and behavioral approaches in overweight girls. The subjects were recruited from Parker Memorial School in Tolland, Connecticut, and two testing periods occurred over an eight week period. Video recordings of each physical activity session were analyzed to determine energy expenditure, exercise intensity, and behaviors during exercise. Data was evaluated for normal distribution, and paired t-tests were used to determine statistical significance. This study showed that the age appropriate before school physical activity intervention was able to increase energy expenditure and exercise intensity and have a positive effect on behavioral approaches in overweight girls.

Building Steprelationships: Emerging Adult Stepchildrens' Perceptions and Experiences of their Stepparents

A grounded theory study was conducted with ten (7 female, 3 male) emerging-adults in stepfamilies to examine their perceptions and experiences of their stepparents, and what factors influence the development and maintenance of these steprelationships. Three primary categories emerged from the data: (1) Stepchildrens' perceptions of their stepparents presence in their lives, including both physical closeness and physical and emotional involvement (2) The perceived level of authenticity within the steprelationship, and (3) The level of clout stepchildren afforded to their stepparents' position within their lives and families. Additional factors found to influence the levels of presence, authenticity, and clout were stepchildrens' emotional maturity, cultural background, relationships with their biological parents, and feelings regarding the use and acquisition of money.

The Impact of Mobile Technology on the Viewing Experience of the Avid Sports Fan

Viewing sports on television is a very different experience than viewing a game in-person. Sports commentators on television are seemingly able to pull up random statistics as soon as something unexpected happens during a game. Because these statistics are discussed on television, any sports fan who wants to watch a game in-person misses out on the opportunity to hear them during the game. This study identifies what statistics, both common and uncommon, are considered important or interesting by avid sports fans who watch a particular sport at least two times per week. In addition, it considers the rise of mobile technology and the effects that this change of trend will have on business opportunities and experiences. The purpose of the project is to find a way to mimic the television viewing experience for fans who are watching in-person through the use of mobile technology, and in particular through the use of iPhone applications.

Covert or Overt Intervention? The Reagan Administration in Latin America

In my thesis I looked at Cold War interventionism by America. In the Post WWII period, many countries were searching for freedom from colonial rule, and many were attracted to the idea of communism or socialism. In this context of a destabilized world and power struggle between the U.S.A and the U.S.S.R., revolutions often became points of interests and parts of this larger power play. Any type of revolution was a destabilization, in a system that was unstable at best, and peace between the powers rested precariously on the idea of “Mutually Assured Destruction.” I would like to look more specifically, at the Latin American Region, which seemed full of upheaval, and was an area of much intervention, especially during the Reagan Administration. This administration had varying goals and conflicts about the region. The large amount of interventionism in the 1980s was in part a response to the Vietnam War, which was seen as an American failure, since prevention of communism did not occur. Following this, American strength needed to be shown again in the international stage, especially in Latin America, due to its close proximity to America. I would like to explore the intervention in Grenada and see if it followed a pattern of intervention in the region. This will be contrasted with the case of Nicaragua, which seemed more typical of interventions in the region. The causes of intervention in the region as well as the reasons these interventions took such different courses will be explored and investigated.

Sleep Disturbance in the Homeless Population: The Relationship between Homelessness, Sleep and Health

Little is known about how sleep disruption impacts physical health among the homeless. The association between homelessness, quality of sleep and physical health were investigated in the current study. Convenience sampling was used to select participants from a pool of people attending the programs of Ecclesia Ministries. Interviews were conducted with 32 persons from the Boston metropolitan area, of whom 23 were currently homeless. The researcher assessed level of sleep disturbance, number of health problems and degree of homelessness using a standard demographic questionnaire, the General Health Questionnaire-12 (GHQ-12) and the Pittsburgh Sleep Quality Index (PSQI). Our results found evidence of significant sleep disturbance as well as significant mental and physical health problems in the sample. Correlational analyses provided partial support for the hypothesis that degree of homelessness impacts both sleep quality and physical health. Future work should investigate whether change in homelessness status alters sleep quality and physical health and also whether interventions may be utilized in this understudied and vulnerable population.

"My One Regret...": The Case for Cultural Immersion in Study Abroad Programs

Study abroad has been an established institution in US universities for almost a century, and hundreds of thousands of students travel to all corners of the world every year. While many list some degree of cultural immersion as a main goal, most students have a difficult time achieving this. Drawing from interviews with twenty-five UConn undergraduates that studied abroad, this study attempts to identify factors that hold students back from cultural encounters. The study also discusses the 'success stories' of undergrads that made significant connections abroad, and highlights the factors that can lead to this (e.g., homestays, jobs, internships).

MacroH2A1 Regulation During the Cell Cycle of Mouse Embryonic Stem Cells

MacroH2A is a core histone variant that plays an important role in the X-inactivation process during differentiation of embryonic stem cells. It has been shown that macroH2A changes in localization during the cell cycle of somatic cells. This study aims to determine how macroH2A changes during the cell cycle of embryonic stem cells. Male and female mouse embryonic stem cells were transfected with a GFP::macroH2A construct and the relationship between macroH2A and the cell cycle was determined using FACS. This study shows that macroH2A is altered during the cell cycle of embryonic stem cells as it is in somatic cells and that in randomly cycling cells, there is a correlation between macroH2A expression and the phases of the cell cycle. High GFP expressing cells are mostly in the G2/M phase and low GFP expressing cells are mostly in the G1 phase. This correlation indicated that macroH2A is replicated with cellular DNA during the S phase resulting in higher expression in the G2/M phase. Future research, such as RT-PCR and differentiation experiments, is needed to further study this relationship and determine whether this change is at the protein or RNA level and how it changes during differentiation.

Tracking the Trends in Inventory Management in the Automobile Manufacturing Industry Throughout the Business Cycle

This paper investigates the trends in inventory management in the automobile manufacturing industry during recessionary vs. non-recessionary periods. It is an empirical approach to testing the validity of the hypothesis that firms which carry leaner inventories perform better throughout the business cycle and are less affected by variability in the economy than less lean firms. The research also hopes to shed some light on how firm's financial statements can be manipulated through discretionary adjustments made by management pertaining to the valuation of inventories.
