Mobile Internet Testing: An analysis of equivalence,individual differences,and reactions

Mobile internet testing (MIT) is the latest cost effective technological push in employment testing. The ability to access assessments via the internet using mobile devices provides increased speed and convenience for both administrators and respondents. In this article, we examine the equivalence of MIT compared with testing on personal computers (PCs) and whether attitudes and other individual differences influence responses and reactions to MIT. Results demonstrated equivalence for a supervisory situational judgment test across testing modes, but not for a cognitive ability test. Significant relationships were found between anxiety and both performance and reactions to mobile assessment. Respondents also reported significantly more positive reactions when tested on a PC versus a mobile device. Future research and practical implications are discussed.     

比较视阈的中美医学伦理学教学——以武汉大学与芝加哥大学为例

中美两国都很重视医者人文素质的培养, 都重视医学伦理学教学。在与芝加哥大学的交流活动中, 武汉大学积极总结经验, 锐意改革, 取得了若干成果。其值得推广的经验包括:注重医学伦理教育的持续性, 构建长效教育机制;注重医学基础课程的道德教化功能, 形成隐性的医德渗透机制;注重临床医生的参与, 确立理论与实践的融通机制;审视中国传统文化特色与医疗现状, 培育域外教学方法的本土化机制;重视医学伦理学学科建设, 建立生命伦理学与医学伦理学的整合机制。     

美国补充与替代医疗体系的变迁及公众影响力

基于美国对补充与替代医学 (Complementary and Alternative Medicine, CAM) 的政策性文件, 结合美国亚马逊公司旗下产品"亚马逊 (美国) "的CAM图书的种类分布和销量情况, 以及美国公民使用CAM疗法的调查数据, 梳理了美国CAM体系变迁及公众影响力。美国政府对CAM的政策及体系界定经历了数次变迁。中医等传统医学及部分疗法在CAM体系内的归类发生过变化。部分CAM疗法被吸纳入美国医疗卫生保健体系。CAM在美国公众中有着巨大影响力。中医在美国的公众影响力主要在于针灸疗法, 且影响力在CAM疗法中并不突出。     

The Quadratic Relationship Between Body Mass Index and Suicide Ideation: A Nonlinear Analysis of Indirect Effects

A nonlinear indirect effects framework was used to investigate potential interpersonal indirect effects (i.e., perceived burden and thwarted belonging) accounting for the nonlinear relationship between body mass index (BMI) and suicide ideation. Using a sample of 338 undergraduates, results revealed a significant quadratic effect of BMI on suicide ideation via perceived burden only, which became significant as BMI fell below 18.00 kg/m² and above 28.00 kg/m². Our results provide novel information relevant for suicide risk screening in the context of weight‐ and health‐related interventions and provide justification for future longitudinal trials assessing suicide risk across the BMI spectrum.     

Relationship between quantity and frequency of alcohol use and indices of suicidal behavior in an elderly Australian sample

Relatively little research has been conducted on the relationship between alcohol misuse and suicidal behavior among the elderly. The current study's aim was to examine whether quantity and frequency of alcohol use and the interaction between these variables are related to current suicidal ideation, previous suicidal ideation/intent, and past suicide attempts in a community sample of 1,010 Australian adults over age 60. Results partially supported our hypotheses. The interaction between quantity and frequency of alcohol use was significant, suggesting that those who use alcohol less frequently but in greater quantities (i.e., binge drinking) are more likely to have a history of suicide attempts.     

Relations among mothers' expressivity, children's effortful control, and their problem behaviors: a four-year longitudinal study

Longitudinal relations between mothers' expressivity, children's effortful control, and their problem behaviors were examined when children (N = 181) were 6.5-10 years old (T2) and again 2 (T3) and 4 (T4) years later. Mothers reported on their expression of positive and negative dominant emotion. Mothers and teachers reported on children's effortful control and externalizing and internalizing problem behaviors. In structural equation models, variables exhibited consistency over time. Further, the relation between mothers' expressivity (positive minus negative dominant emotion) at T2 and children's externalizing problems at T4 was mediated by T3 effortful control. The same process of mediation was significant for teacher- but not mother-reported internalizing problems. The results provide one explanation for how emotion-related socializing behaviors influence children's problem behaviors.     

Warning signs for suicide: theory, research, and clinical applications

The current article addresses the issue of warning signs for suicide, attempting to differentiate the construct from risk factors. In accordance with the characteristic features discussed, a consensus set of warning signs identified by the American Association of Suicidology working group are presented, along with a discussion of relevant clinical and research applications.     

WAIS-III task perception and performance as a function of stopwatch display

Examiner's instructions for the Wechsler Adult Intelligence Scale-Third Edition indicate that stopwatch display is optional. Since verbal instructions do not consistently inform examinees whether a subtest is timed, examinees may rely upon the visual cue of the stopwatch. Furthermore, examinees' understanding of the actual subtest demands may affect their performances. In the present study, 58 volunteers were randomly assigned to two groups, one in which the examiner displayed the stopwatch and one in which the stopwatch was concealed. Participants were administered the first five subtests. Predictions were that (1) participants to whom the stopwatch was displayed would more accurately perceive whether the subtests were timed, and (2) participants who accurately understood the demands of subtests would score higher than those who did not. Results supported the first hypothesis for three subtests out of five, one remaining inconclusive due to a ceiling effect. The second hypothesis was not supported. Both the implications and limitations of the present study are discussed.
