Analysis of perception of training in graduates of the Faculty of Medicine at Universidad de Castilla-Mancha

IntroductionProblem-based learning has been a key component of the teaching method employed at the Faculty of Medicine at the University of Castilla La Mancha (UCLM) in Albacete, Spain since its creation. The aim of this study was to evaluate perceptions of training among residents who graduated from the first three years of the UCLM Degree in Medicine.MethodsUsing the Jefferson Medical College postgraduate rating form, residents rated their performance in four areas of clinical competency (medical knowledge, data gathering skills, clinical judgment, and professional attitudes) at the beginning of residency training in comparison with colleagues from other faculties. The construct validity of responses was evaluated using Cronbach's alpha and exploratory factor analysis.ResultsOver half the respondents (57.8%) considered that they had received better training than peers from other medical schools, and 98.5% felt that their general performance in the four competencies analyzed was similar or superior to that of their colleagues. Factor analysis revealed two major factors: “the physician as scientist” and “the physician as manager and communicator”.ConclusionsOur study shows that graduates from the UCLM Faculty of Medicine perceive their training, which is largely based on problem-based learning, as satisfactory.     

“America Will Not Tolerate Slave Traders”: Counter-Trafficking Policies and US Power

The US government has implemented an ambitious set of policies designed to combat human trafficking and sex trafficking in women and girls in particular. This article argues that anti-trafficking discourse and policy can be understood as a project to sustain and strengthen US power. This power has been wielded through the use of foreign aid, which influences the actions of both state and non-state actors overseas. Existing policies reinforce unilateralism and executive-branch dominance. Policymakers have also used gender strategically to moralize their actions and assert global leadership on this issue. Gender is thus deployed to serve US interests.     

The Use of Humor With Older Adults Aging in Place

As more older adults seek ways to remain in their homes during their “golden years,” humor has proven to be a worthwhile intervention that reduces stress and provides a hopeful, playful, and optimistic environment. Development of creative and supportive housing situations for older adults combined with the use of modern technology (e.g., the Internet and computer devices used in the home), aid in bringing humor to the older adult. This article addresses some of the challenges that older adults face and the way that the use of humor can assist them to meet these challenges.     

"天书降神"新议--北宋与契丹的文化竞争

宋真宗"天书降神"一事,不但为当时"不语怪力乱神"的儒者反对,亦为今世秉后见之明,崇尚"理性"、"科学"的学人严厉批判.但元儒修撰<宋史>,于此曾表"同情之理解".本文即以此为起点,以考据为基础,试图揭示"天书降神"背后的文化意蕴和实际效果,并提出与亨廷顿"文明冲突"(the clash of civilizations)不同的观念--"文化竞争"(the cultural struggle).

云南回族的他称--"潘塞"、"潘西"和"帕西"辨析

历史上云南回族马帮商人在云南境内外各条商道上不绝于途,不少人还定居缅甸和泰国.缅族称云南回族为"潘塞"(旧译"潘泰"),掸族称之为"潘西".在国内,西双版纳傣族称回族为"帕西".海外学者对缅语"潘塞"一词的语源争议不休,众说纷纭.本文论述提出(一)"潘塞"、"潘西"和"帕西"原为印度、缅甸一带民间对穆斯林的泛称,尔后用以称呼云南回族,三者系同一名词,仅读音有微小差异;(二)三者均由中世纪以来印度民间称呼波斯人的"帕尔西"(Patsi)一词演变而来.

供应突发事件下基于CVaR的供应链订货决策及协调

供应突发事件下,引入条件风险值(conditional value at risk-CVa R)刻画了零售商的运营目标,构建了收益共享契约下的供应链订货模型,着重研究了CVa R下的供应链协调及零售商最优订货量对供应商可靠性及对其自身的风险规避系数的敏感性。研究表明:收益共享契约具有一定的鲁棒性,能协调突发事件风险下的供应链;风险规避型零售商的最优订货量总是不小于风险中性情况,且风险规避程度越高,订货量越大;最优订货量对供应商可靠性均值的敏感性不依赖于零售商的风险规避程度,且均值越小,最优订货量越大,这与风险中性情况是类似的;最优订货量对供应商可靠性标准差的敏感性则依赖于零售商的风险规避程度,当零售商的风险规避程度较高时,供应可靠性标准差越大,最优订货量越大,这与风险中性情况是相反的。
