Electronic performance self-monitoring and engineered labor standards for “man-up” drivers in a distribution center

Electronic Performance Monitoring (EPM) represents the future of performance feedback where supervisors can electronically monitor the amount and quality of work an employee is producing and have objective indicators of employee performance immediately available and visible. In this study, immediate performance feedback and self-monitoring was delivered to employees in the warehouse on wireless vehicle-mounted computers. Order picking performance for “man-up” drivers (N = 10) was improved by three cases per hour per person in an auto-parts after-market distribution center when an intervention package that included the depiction of goal times and immediate performance feedback on wireless vehicle-mounted computers and a newly developed engineered labor standard (ELS). The implications of these findings and limitations are discussed in terms of operational and ethical issues regarding EPM in large industrial settings.     

The Relevance of Intention in Argument Evaluation

The paper discusses intention as a rhetorical key term and argues that a consideration of rhetor’s intent should be maintained as relevant to both the production and critique of rhetorical discourse. It is argued that the fact that the critic usually has little or no access to the rhetor’s mind does not render intention an irrelevant factor. Rather than allowing methodological difficulties to constrain critical inquiry, I suggest some ways in which the critic can incorporate the rhetor’s intention in evaluating argumentation. To this end, a standard of fairness is presented. The paper was presented at the 6th International Conference on Argumentation in Amsterdam, June 27–30, 2006.     

Bulimia nervosa in undergraduate women: Factors associated with internalization of the sociocultural standard of thinness

Diverse areas of research and theory are integrated in an attempt to better understand the specific risk factors for bulimia nervosa identified in the literature. It is suspected that the interplay of risk factors may be unique to different groups of individuals who develop bulimia. Further, it is proposed that specific determinants be studied individually to determine their particular influence in the etiology of bulimia. It is suggested that the investigation of specific risk factors for bulimia in certain groups will benefit researchers and clinicians in gaining a better conceptual understanding of the process involved in the development of the disorder. This article focuses on the determinants of a specific risk factor (i.e., internalization of the sociocultural standard of thinness) for bulimia in undergraduate women, a group identified as particularly vulnerable to this disorder. Research and theory are integrated to suggest that a combination of specific individual differences, family, and social factors make some undergraduate women more vulnerable to the influence of the sociocultural standard of thinness and bulimia. Suggestions for the inclusion of these psychosocial factors in future empirical investigations and treatment programs are also discussed.     

Effect of anosmia on the behavior of standard non-aggressive male mice opponents during agonistic encounters

This study assessed whether the differences observed in a previous experiment [Martinez M, Salvador A, Simon VM (1994): Aggressive Behavior 20:441–451] in the behavior of isolated male mice over several agonistic encounters in which they confronted either an “anosmic” or an “intact” non-aggressive “standard opponent” were due to the differences in the behavior of the opponents themselves. Ethologically-inspired analysis was used to assess the behavior of the opponents during the first agonistic encounter. Anosmic opponents spent less time in social investigation and defense and more time in immobility than intact ones. These results suggest that the differences in the behavior of the opponents could be one of the causes of the differences observed in the behavior of the aggressive males confronting them. However, more research is needed to study if other variables, such as the production of odors, are also affected by the state (deprived or intact) of the olfactory sense. These findings provide additional support for the view that the type of opponent used in studies on intermale aggression is of paramount importance.Aggr.

Effects of prenatal cocaine and genotype on intermale agonistic behavior in Mus musculus

We exposed the pups of three F₁ genotypes of mice to a daily regime of cocaine by injecting their mothers (all C57BL/10J strain) on days 7–18 of gestation with 20 mg/kg subcutaneously. Pups of the cocaine and control groups did not differ on measures of maternal and pup health or size. Male pups were weaned and isolated at 21 days of age and their behaviors measured in an intermale aggression situation at about 80 days of age. Treated and untreated males of each F₁ genotype were paired in dyads with either a C3H/HeJ (hawk-like) or AKR/J (retaliator-like) standard tester male. Standard tester males were not exposed to cocaine. Cocaine treatment alone reduced the overall level of aggression in dyads, and in interaction with genotype or the standard tester it altered the behavior of dyads in all phases of social interaction: the initiation, content, and outcome. Standard testers used as behavioral probes, differentiated cocaine and control males with respect to their stimulus and behavioral qualities. Aggr.

过度医疗的伦理学会诊及其治疗处方--兼论临床诊治最优化伦理准则

过度医疗是一个极其复杂的医学-社会问题,给予医学伦理学的解析是解决这一问题的最基本的工作。目前,服务质量虚高而服务收费真高是过度医疗的实质和特点;它貌似临床最优化服务,但却严重背离临床诊治最优化准则,对二者进行鉴别诊断是必要的、可能的;伦理学会诊的结论是：该病为疑难病综合征,由医者医学伦理素质低下、医院管理背弃伦理理念、医改政策中伦理机制缺席等多病因相互作用所致;所以,根治过度医疗的处方必须是全方位的、系列连续的、标本兼治的。     

On the alleged normative significance of a platitude

It seems to be a platitude that the belief that p is correct iff it is true that p. And the claim that truth is the correct‐making feature of belief seems to be just another way of expressing this platitude. It is often thought that this indicates that truth constitutes a normative standard or criterion of correctness for belief because it seems to follow from this platitude that having a false belief is believing wrongly, and having a true belief is believing rightly or correctly. In this paper, I aim to show that when we judge the platitude in question to be indisputably true, we do not endorse that truth is normative for belief but merely the triviality that the belief that p is true iff it is true that p.     

Temporal dynamics in attention bias: effects of sex differences,task timing parameters,and stimulus valence

New methods of calculating indices from the dot-probe task measure temporal dynamics in attention bias or fluctuations in attention bias towards and away from emotional stimuli over time. However, it is unclear how task-specific parameters such as stimulus valence and stimulus onset asynchrony (SOA) as well as participant sex affect temporal dynamics in attention bias. To address this, male and female participants (N?=?106) completed either a fearful or happy face dot-probe task with four levels of SOA (84?ms, 168?ms, 336?ms, and 672?ms). Results suggest that temporal dynamics in attention bias are (1) greatest at the longest SOA, (2) greater in females, and (3) insensitive to stimulus valence. These findings indicate that participant sex and task timing, but not stimulus valence, are related to temporal dynamics in attention bias and should be considered in future studies utilizing this approach.     

Associations of depression,anxiety and PTSD with neurological disability and cognitive impairment in survivors of moyamoya disease

Depression, anxiety and posttraumatic stress disorder (PTSD) are common complications of cerebrovascular diseases. However, they were seldom explored in Moyamoya Disease (MMD) survivors. In this study, we measured the prevalence of depression, anxiety and PTSD in MMD survivors. We evaluated the association of mental disorders with neurological disability and cognitive impairment, and further find out the independent protective and risk factors of neurological disability and cognitive impairment. In MMD survivors, the prevalence of these three mental disorders is high, 46.7% for depression, 50% for anxiety and 47.5% for PTSD. Anxiety and PTSD were significantly associated with more severe neurological disability (p = 0.039 and < 0.001); depression and anxiety were significantly associated with greater cognitive deficiency (p = 0.004 and 0.002). We further found PTSD was the only risk factor associated with neurological disability, and the corresponding odds ratio (OR) and 95% confidence interval (CI) was 81.74 (9.91–674.17); depression and anxiety were risk factors associated with cognitive impairment, and the corresponding OR and 95%CI were 2.73 (1.10–6.81) and 3.37 (1.29–8.78). Therefore, these three mental disorders were associated with more severe neurological disability and greater cognitive deficiency in MMD survivors.     

The association between retrospective outcome evaluations and pre-post-treatment changes in psychodynamic group-psychotherapy

In the present study of 203 patients in psychodynamic group psychotherapy, we explore associations between patient and therapist global retrospective outcome evaluations (ROE), and pre-post-treatment changes on the Symptom Check List 90 Revised (SCL-90-R) and non-symptomatic focus of therapy. There were no significant associations between ROE, diagnoses and demographic variables, and pre-treatment SCL-90-R associations were negligible (less than 4% of overlapping variance). SCL-90-R subscale improvement expressed as residual gain score explained the overall largest percent of variance in both patients and therapists (44% and 25%, respectively) when compared with raw difference scores (32% and 18%), and percent reduction from baseline (34% and 23%). Moreover, ROE/end-state adjustment associations were substantial (42% and 24%). Therapists' evaluation of change showed the strongest association with improvement in non-symptomatic focus of therapy, while patients' evaluation had the strongest association with improvement in SCL-Depression. It is concluded that retrospective evaluations reflect changes related to treatment. However, unexplained variance may be independent of symptomatic state, and associated with personality factors or domains not captured by standard questionnaires.
