Effects of discriminatory interview questions and gender on applicant reactions

Justice and signalling theory were used to explain the effects of discriminatory interview questions on applicant reactions. Participants were randomly assigned to a hypothetical interview condition with four, two or no discriminatory questions. Discriminatory questions had a significant negative effect on participant’s reactions to the interview and interviewer; perceptions of employee treatment; and intentions to pursue employment, accept a job offer, and recommend the organization to others. Participants also responded less favorably to a female interviewer, and female interviewees reported more negative perceptions. In addition, a sequential model was supported in which discriminatory questions had a negative effect on reactions toward the interview and interviewer; reactions were positively related to organizational attractiveness; and organizational attractiveness was positively related to intentions to pursue employment, accept a job offer, and recommend the organization.     

评价和控制药物不良反应的认识与思考

用科学的世界观和方法论指导药物不良反应的评价和控制。从药物不良反应的发生机制、临床表现、因果关系的判定原则出发,与马克思主义哲学的基本观点相结合,提出了几点认识和思考。药物治疗作用与副作用既对立又统一;药物治疗效应向毒性反应的转变是量变到质变的过程;药物过敏反应的发生是内因外因相互作用的结果;药物与不良反应联系强度的判定必须符合前因后果性;药物与不良反应联系强度的判定必须排除混杂因素的干扰,找到内在的、本质的联系。     

Primes, contingent attention, and training: effects on a child's motor behavior

The use of primes, contingent attention, and training sessions to assess a child's engagement and skill in six large motor activities was examined using a combination reversal and multiple-baseline design. Assessment was based on four levels: proximity to equipment, touching equipment, unskilled participation, and skilled participation. Before training, priming (suggestion to the child) was more effective than contingent attention for increasing the subject's engagement (but not skill) in five activities and for increasing skilled participation in one activity. Training of four activities in the natural environment effectively increased the subject's skill level in five activities. Thus, training appeared to generalize to one of these five activities in this setting and also to skillfully executed stair climbing in an adjoining setting. After training, primes and contingent attention were sufficient to maintain both the subject's skill level and engagement in all activities. Postchecks in the same setting the following semester with different teachers revealed only slight increases in participation, as compared to previous baselines, but all participation was at the skilled level. Social interaction, which was not experimentally manipulated, did not systematically vary in relation to changes in experimental conditions.     

Developmental dyspraxia and developmental coordination disorder

This article discusses the role developmental dyspraxia plays in developmental coordination disorder (DCD), based upon a review of literature on apraxia, developmental dyspraxia, and DCD. Apraxia and dyspraxia have often been equated with DCD. However, it is argued that apraxia and dyspraxia primarily refer to the problems of motor sequencing and selection, which not all children with DCD exhibit. The author proposes to distinguish developmental dyspraxia from DCD. Other issues discussed include the assessment, etiology, and treatment of developmental dyspraxia and DCD, and the relationship between DCD and learning disabilities. A research agenda is offered regarding future directions to overcome current limitation.     

Norms for 439 action events: Familiarity,emotionality, motor activity,and memorability

A total of 128 male and female university students having Swedish as their mother tongue rated 439 actions on a 7-point scale in the dimensions of Familiarity, Emotionality, Motor Activity, and Memorability under instructions to imagine themselves performing each action (e.g., “to roll a ball”, “to break a match”). Overall mean ratings were higher for women than for men in all four dimensions. High reliabilities were obtained in each scale. Intercorrelations between the dimensions were low to moderate, indicating that different characteristics of the actions were assessed. It is demonstrated that the ratings of the four dimensions are in agreement with previous categorisations of actions along the same or similar dimensions and with findings related to memory performance. Furthermore, control studies performed on the Familiarity dimension show that norm values are highly correlated with ratings given by participants in standard enacting and nonenacting conditions and with ratings in a condition where objects were present. These norms offer possibilities to control for and vary item characteristics of importance in the study of actions and the memory of actions.     

The influence of geographic region on the seasonality of early motor development

This investigation was conducted to determine whether the strong seasonality effect on infant motor development that has been noted in moderate climates would be replicated with infants born in a geographic region with more extreme conditions. One hundred and forty-five full-term infants (72 males, 73 females) born in Edmonton, alberta were assessed using the Alberta Infant Motor Scale (AIMS) at 7 months of age. No seasonality effects on the AIMS total scores or the prone, supine, sitting, or standing subsection scores were detected. A weak and statistically non-significant correlation was obtained between the average monthly AIMS scores and the average monthly temperatures 7 months after birth. These results suggest that extreme climatic conditions in urban geographic regions may dampen effects of season of birth on infant motor development.     

Predicting preschool motor and cognitive performance in appropriate-for-gestational-age children born at ≤ 32 weeks gestation

Although many follow-up studies have been performed on preterm infants, little attention has been devoted to prediction of motor skills in the preschool or school years. We studied the relationship of performance on the Bayley Scales of Infant Development at a mean corrected age of 21 months to performance on the McCarthy Scales of Children's Abilities at a mean corrected age of 44.7 months for 43 appropriate-for-gestational-age (AGA) children born at ≤ 32 weeks gestation. Motor scores were stable over time with a significant correlation between the Bayley Psychomotor Developmental Index (PDI) and the McCarthy Motor subscale (r = 0.60; p = 0.0001). Scores of cognitive abilities also showed a significant correlation between the Bayley Mental Developmental Index (MDI) and the McCarthy General Cognitive Index (r = 0.42; p = 0.009). Small-for-gestational-age (SGA), very low-birthweight (≤ 1500 grams) children scored lower on the McCarthy General Cognitive Index (p = 0.01) and on the Motor subscale (p = 0.047) than the AGA children. We concluded that motor performance of AGA children born at ≤ 32 weeks gestation is stable from toddlerhood to preschool age. We suggest that SGA children be excluded from studies of motor performance of prematurely born children.     

Parental grief following the death of an infant—a follow-up over one year

The course of parental bereavement during the first year following an infant's death was investigated. Also, the differences in mothers' and fathers' reactions, the differences according to the mothers' occupational role, and the similarities in couples' reactions were studied. From a total sample of 59 families, 13 families answered their questionnaires at all three time points (1, 6 and 13 months), 22 families responded at two time points, and 37 families responded at some point following the loss. Measures relating to anxiety, depression, bodily discomfort, general well being and impact of event were used at the three time points. The results showed that grief, as measured by the different inventories, decreased over time. The decrease was most evident from 6 to 13 months, and most prominent in women. A considerable number of the parents were still actively dealing with the loss all through the first year of bereavement. In most couples the mother reported most distress. Mothers were significantly more depressed than fathers at all time points, and mothers also had significantly higher anxiety and lower general health at 1 and 13 months, and intrusive scores of 1 and 6 months. Women at home evidenced more grief at all three time points than women employed outside the home. A high or low score in one spouse was more strongly correlated with a similar score in the other at 1 and 13 months, than at 6 months. The implications for counselling of parents, with special emphasis on the employment situation of the mother, is emphasized.
