The Impact

Background: The American College of Surgeons (ACS) holds an annual clinical congress which provides the opportunity to present innovative research to academic and community surgeons from around the globe. The purpose of this study was to evaluate the publication rate of poster abstracts presented at the 2009 American College of Surgeons Clinical Congress to assess the factors influencing publication and determine the impact factor of these journals.Methods: All posters presented at the 2009 ACS were included in the study. A Pubmed-Medline search was performed to identify a matching journal article. Topics, country of origin, study type, study center and publication year were tabulated. Journals and impact factors of publication were noted.Results: Of the 333 poster abstracts presented, 62 (18.6%) were published as full-text articles. Two studies published well in advance of the meeting were removed. 36/60 (60%) of the published studies were from The United States. The average time to publication was 16.8 months. 51/60 (85%) of the studies were conducted in academic institutions. The average impact factor was 2.88. The median impact factor for studies originating from the United States was 3.3 (0.71-4.5). The median impact factor for international studies was 2.38 (0-7.22). This observation did not reach statistical significance (p=0.102) 8 (13.3%) of these manuscripts were published in the Journal of the American College of Surgeons (the official journal of the meeting). There were several abstract characteristics found to be associated with a higher publication rate. A higher rate was found for abstracts for randomized clinical trials, basic science studies, and university programs. The rates did not differ between author specialties.Conclusion:The publication rate for abstracts presented at the 2009 ACS clinical congress was lower than rates from other fields of medicine. Factors leading to failure to publish were non-randomized trials, non-university affiliation and single center studies. Encouraging authors to submit their presentations for full-text publication might improve the rate of publication. Authors should be wary of accepting poster abstracts as dogma; authors should refrain from citing them in publications especially if they are from outside the United States.

The Impact

Abstract Background: Travel patterns of humans play a major part in the spread of infectious diseases. This was evident in the geographical spread of COVID-19 in the United States. However, the impact of this mobility and the transmission of the virus due to local travel, compared to the population traveling across state boundaries, is unknown. This study evaluates the impact of local vs. visitor mobility in understanding the growth in the number of cases for infectious disease outbreaks. Methods: We use two different mobility metrics, namely the local risk and visitor risk extracted from trip data generated from anonymized mobile phone data across all 50 states in the United States. We analyzed the impact of just using local trips on infection spread and infection risk potential generated from visitors' trips from various other states. We used the Diebold-Mariano test to compare across three machine learning models. Finally, we compared the performance of models, including visitor mobility for all the three waves in the United States and across all 50 states. Results: We observe that visitor mobility impacts case growth and that including visitor mobility in forecasting the number of COVID-19 cases improves prediction accuracy by 34. We found the statistical significance with respect to the performance improvement resulting from including visitor mobility using the Diebold-Mariano test. We also observe that the significance was much higher during the first peak March to June 2020. Conclusion: With presence of cases everywhere (i.e. local and visitor), visitor mobility (even within the country) is shown to have significant impact on growth in number of cases. While it is not possible to account for other factors such as the impact of interventions, and differences in local mobility and visitor mobility, we find that these observations can be used to plan for both reopening and limiting visitors from regions where there are high number of cases.

The Impact

The United States' laissez-faire approach to moral rights legislation has left many academics questioning the impact that these laws have on artists' welfare. In using artists' income as one component of measuring overall well-being, states with additional statewide moral rights legislation have been shown to contribute to more significant artist losses, in contrast to states with only federal legislation. At the same time, moral rights laws have been shown to have no impact on artists' choice of residency, leaving some artists possibly disadvantaged regarding their choice of residency. Utilizing a difference in differences framework, this paper explores the impact of moral rights legislation on artists' weekly incomes between moral rights states of varying outputs of GDP. Although results suggested that artists would lose approximately $0.18 per one billion dollar increase in GDP at the statewide level, after conducting an additional t-test, these findings were shown to have no statistical significance. Several limitations, most prominently a lack of data availability in the pre-law values required for the difference in differences framework, may have contributed to these findings. These indeterminate results leave the question of whether some artists remain economically disadvantaged as a result of moral rights legislation uncertain.

The Impact

Clinical reasoning (CR) is a key learning domain for physical therapy educators and a core skill for entry-level practitioners. Integrated clinical experience (ICE) and problem-based learning (PBL) have each been reported to improve interpersonal and social domains, while promoting knowledge acquisition and CR. Unfortunately, studies monitoring CR during ICE with concurrent PBL in physical therapy education are sparse. We hypothesized that ICE with concurrent PBL would be associated with improved self-reported CR in third-year student physical therapists (PTs) in the United States. The Self-Assessment of Clinical Reflection and Reasoning (SACRR) survey was administered to 42 student PTs at the beginning and end of their third and final year of didactic training. Between the pretest and posttest analyses, the participants completed faculty-led ICE and PBL coursework for 16 weeks. The overall SACRR score and 26 individual item scores were examined. The Wilcoxon rank-sum test and paired t-test were used, with statistical significance accepted at P< 0.05. Significant improvements were observed in the overall SACRR score (P< 0.001), including 6 of the 26 survey items centered around decision-making based on experience and evidence, as well as self-reflection and reasoning. ICE with PBL was associated with improved self-assessed CR and reflection in third-year student PTs in the United States. Monitoring the impact of curricular design on CR may improve educators’ ability to enhance cognitive and psychomotor skills, which underscores the importance of increasing the explicit use of theoretical frameworks and teaching techniques for coping with uncertainty as a way of enhancing entry-level training.

The Impact

Soon after 9/11 a research project to study new immigration into the Dallas Fort Worth metropolitan area got under way. In the questionnaire that was administered to 600 immigrants across five different immigrant populations (Asian Indians, Vietnamese, Mexicans, Salvadorans, and Nigerians) between 2003 and 2005 we decided to include a question about the impact of 9/11 on their lives. We asked: “How has the attack on the World Trade Center on September 11, 2001 affected your position as an immigrant in the United States?” This article analyzes the responses to this question, looking at similarities and differences across different immigrant populations. It also addresses the broader issue of how 9/11 has affected both immigration policy and attitudes toward the foreign-born in the United States.

The Impact

Foreign aid has been the subject of much examination and research ever since it entered the economic armamentarium approximately 45 years ago. This was the time when the Second World War had successfully ended for the Allies in the defeat of Germany and Japan. However, a new enemy, the Soviet Union, had materialized at the end of the conflict. To counter the threat from the East, the United States undertook the implementation of the Marshal Plan, which was extremely successful in rebuilding and revitalizing a shattered Western Europe. Aid had made its impact. The book under review is by three well-known economists and is the outcome of a study sponsored by the Department of State and the United States Agency for International Development. The major objective of this study was to evaluate the impact of assistance, i.e., aid, on economic development. This evaluation however, was to be based on the existing literature on the subject. The book has five major parts: Part One deals with development thought and development assistance; Part Two looks at the relationship between donors and recipients; Part Three evaluates the use of aid by sector; Part Four presents country case-studies; and Part Five synthesizes the lessons from development assistance. Part One of the book is very informative in that it summarises very concisely the theoretical underpinnings of the aid process. In the beginning, aid was thought to be the answer to underdevelopment which could be achieved by a transfer of capital from the rich to the poor. This approach, however, did not succeed as it was simplistic. Capital transfers were not sufficient in themselves to bring about development, as research in this area came to reveal. The development process is a complicated one, with inputs from all sectors of the economy. Thus, it came to be recognized that factors such as low literacy rates, poor health facilities, and lack of social infrastructure are also responsible for economic backwardness. Part One of the book, therefore, sums up appropriately the various trends in development thought. This is important because the book deals primarily with the issue of the effectiveness of aid as a catalyst to further economic development.
