To show how the case of Mary Shelley’s Victor Frankenstein brings light to the ethical and moral issues raised in Institutional Review Board (IRB) protocols, we nest an imaginary IRB proposal dated August 1790 by Victor Frankenstein within a discussion of the importance and function of the IRB. Considering the world of science as would have appeared in 1790 when Victor was a student at Ingolstadt, we offer a schematic overview of a fecund moment when advances in comparative anatomy, medical experimentation and theories of life involving animalcules and animal electricity sparked intensive debates about the basic principles of life and the relationship between body and soul. Constructing an IRB application based upon myriad speculations circulating up to 1790, we imagine how Victor would have drawn upon his contemporaries’ scientific work to justify the feasibility of his project, as well as how he might have outlined the ethical implications of his plan to animate life from “dead” tissues. In Mary Shelley’s Frankenstein, Victor failed to consider his creature’s autonomy, vulnerability, and welfare. In this IRB proposal, we show Victor facing those issues of justice and emphasize how the novel can be an important component in courses or workshops on research ethics. Had Victor Frankenstein had to submit an IRB proposal tragedy may have been averted, for he would have been compelled to consider the consequences of his experiment and acknowledge, if not fulfill, his concomitant responsibilities to the creature that he abandoned and left to fend for itself.  相似文献

Most studies of ideal-body media effects on body image focus on the extreme thinness of the models, not their idealness. In modern media, this idealness is often created or maximized via digital image editing. This experiment tested the effects of image editing outside the research-typical context of exclusive thinness. Original unretouched photographs were manipulated by a professional retoucher to produce unretouched and retouched image conditions. In a third condition (retouched-aware), the retouched images were explicitly labeled as retouched. Adolescents ( N = 393, average age 15.43) were randomly assigned to one of these conditions or a no-exposure control, and they completed a questionnaire following exposure. Objectified body consciousness increased and physical self-esteem decreased among male and female adolescents in the retouched-aware condition only. This boomerang effect of retouching awareness is explored in the discussion.  相似文献

The dominant perspective on expatriation characterizes the process as a continuing adaptation to existing job demands on an international assignment. Another, less studied perspective, emphasizes that expatriates can initiate tactics to acquire task, interpersonal, and affective resources for shaping their assignment experiences. Adopting a positive organizational scholarship lens and drawing on the job demands–resources model, we simultaneously examine both of these reactive demand‐based and proactive resource‐based pathways to expatriate retention. We propose that cross‐cultural uncertainty demands and expatriate‐initiated resource acquisition tactics both influence adjustment and embeddedness. Thus embeddedness works alongside adjustment to drive expatriates’ plans to remain in the international position, which in turn leads to actual retention. Using evidence from 2 separate panel studies (one with 2 waves and the other with 4 waves of data), we demonstrate the importance of the resource‐based pathway for expatriate assignments.  相似文献

This study extended previous research (Motowidlo, Borman, & Schmit, 1997) on antecedents of job performance by testing for independent effects of prosocial and technical knowledge in a sample of 208 medical students. Results show that prosocial knowledge is uncorrelated with technical knowledge and that it contributes incremental variance to clinical performance in Primary Care after accounting for technical knowledge and clinical skill. Findings indicate Agreeableness is an important correlate of prosocial knowledge but not of technical knowledge. Unexpectedly, cognitive ability is not significantly related to either kind of knowledge or clinical performance. These results reinforce the idea that knowledge is a primary determinant of performance and that one type of knowledge, prosocial, has roots in Agreeableness, whereas a different type of knowledge, technical, does not.  相似文献

In many human movement studies angle-time series data on several groups of individuals are measured. Current methods to compare groups include comparisons of the mean value in each group or use multivariate techniques such as principal components analysis and perform tests on the principal component scores. Such methods have been useful, though discard a large amount of information. Functional data analysis (FDA) is an emerging statistical analysis technique in human movement research which treats the angle-time series data as a function rather than a series of discrete measurements. This approach retains all of the information in the data. Functional principal components analysis (FPCA) is an extension of multivariate principal components analysis which examines the variability of a sample of curves and has been used to examine differences in movement patterns of several groups of individuals. Currently the functional principal components (FPCs) for each group are either determined separately (yielding components that are group-specific), or by combining the data for all groups and determining the FPCs of the combined data (yielding components that summarize the entire data set). The group-specific FPCs contain both within and between group variation and issues arise when comparing FPCs across groups when the order of the FPCs alter in each group. The FPCs of the combined data may not adequately describe all groups of individuals and comparisons between groups typically use t-tests of the mean FPC scores in each group. When these differences are statistically non-significant it can be difficult to determine how a particular intervention is affecting movement patterns or how injured subjects differ from controls. In this paper we aim to perform FPCA in a manner allowing sensible comparisons between groups of curves. A statistical technique called common functional principal components analysis (CFPCA) is implemented. CFPCA identifies the common sources of variation evident across groups but allows the order of each component to change for a particular group. This allows for the direct comparison of components across groups. We use our method to analyze a biomechanical data set examining the mechanisms of chronic Achilles tendon injury and the functional effects of orthoses.  相似文献

We report two studies that investigate single‐response situational judgment tests (SJTs) as measures of job knowledge. Study 1 examines relationships between job knowledge measured by a single‐response SJT, personality, and performance for museum tour guides. Study 2 extends Study 1's findings with a sample of volunteers using a single‐response SJT about volunteerism. In both studies, personality was related to knowledge, and knowledge predicted performance. In Study 2, knowledge accounted for incremental variance in performance beyond personality, but personality added no incremental variance beyond knowledge. Results suggest that knowledge of effective behavior and knowledge of ineffective behavior are separate constructs. These studies demonstrate the validity of single‐response SJTs and provide evidence that knowing what to do and what not to do are separate domains.  相似文献

A widely held belief exists that women are more romantic and tend to fall in love faster than men. Responses from 172 college students indicated that although both men and women believe that women will fall in love and say "I love you" first in a relationship, men reported falling in love earlier and expressing it earlier than women reported. Analyses also showed no sex differences in attitudinal responses to items about love and romance. These results indicate that women may not be the greater "fools for love" that society assumes and are consistent with the notion that a pragmatic and cautious view of love has adaptive significance for women.  相似文献

The authors reexamined reported effects of age, illumination, and stationary visible structure on the net center of pressure (COP) derived from dual, side-by-side force plates (J. Kinsella-Shaw, S. Harrison, C. Colon-Semenza, & M. Turvey, 2006 ) from the perspective of axial postural control. They questioned how left and right COP(x)(t), COP(y)(t), and vertically oriented ground reactive force, GRF(z)(t), coordinated during quiet standing. The Cross-recurrence Quantification (CRQ) revealed that coordination was primarily between fluctuations of similar direction, with coordination of left and right COP(y) (t) (anteroposterior fluctuations) dominant. CRQ also revealed that (a) illumination and structure affected the interlimb dynamics of older (M age = 72.2 ± 4.90 years) participants more than their younger (M age = 22.8 ± 0.83 years) counterparts, and (b) older participants exhibited greater interlimb entrainment (dynamical stability) in the presence of greater interlimb noise.  相似文献

The authors evaluated the psychometric properties of the Firefighter Coping Self-Efficacy (FFCSE) Scale, a new measure developed to assess firefighters' perceived competence in managing stressful and traumatic experiences encountered on the job. Two samples of firefighters completed the FFCSE Scale at two different time points. Exploratory factor analysis yielded a unidimensional structure, which was further supported with confirmatory factor analysis using a second sample. Internal consistency of the measure was excellent. Analysis of cross-sectional data indicated FFCSE was positively associated with measures of psychological well-being and social support, and negatively associated with work-related stress and psychological distress. FFCSE also uniquely contributed to the variance in psychological distress, over and above variables previously shown to be associated with distress among this population. Implications and suggestions for future research are discussed.  相似文献

解读曼殊五部曲   总被引:1,自引:0,他引:1  
苏曼殊是清末民初萃集革命与刨作于一身的“奇人异僧”。从革命的角度说,他意志坚定,积极投身于孙中山领导的资产阶级民主革命,为推翻清朝统治和袁世凯帝制尽心竭力;从创作的角度说,他多才多艺,以风格独特的诗歌、小说、散、翻译、绘画树帜坛,赢得生前和身后无数读的击节和赞赏;从身份的角度说,他是个亦僧亦俗、亦侠亦儒的革命和艺家。他曾获得的桂冠大体停留在不大反映本质的“诗僧”、“情僧”、“风流和尚”、“革命和尚”等一类称号上,然而随着这位传奇的历史人物的“真面目”越来越清晰呈现于世,而不再继续充当人们揣测的对象。  相似文献
