Vertical force and wrist deviation angle when using a walker to stand up and sit down

Research investigating walkers suggests that safety and assistance for the elderly with weak lower limbs were important. However, the relationship between the use of a walker and the upper limbs has received little investigation. Standing up and sitting down are important daily activities. Therefore, the aim of this study was to explore wrist deviation and vertical force among elderly individuals using a walker for assistance to stand up and sit down. In total, 64 elderly volunteers (M age = 80.22, SD = 9.36) were enrolled. Data were obtained from four load cells and a twin-axis wrist goniometer. Wrist deviation and vertical force were examined when participants used a walker with horizontal handles to assist in standing up and sitting down. Significant wrist angle deviation occurred with the use of a walker, with dorsiflexion of the right hand greater than that of the left. Males exerted significantly greater vertical force. In the sitting position, greater ulnar deviation was seen among experienced walker users, whereas during standing, experienced users exhibited greater dorsiflexion. The horizontal handles of most marketed walkers may cause user wrist deviations, suggesting researchers should pursue improvements in walker design.     

An item response theory analysis of the Impulsive Behaviors Checklist for Adolescents

This study used item response theory (IRT) to examine the Impulsive Behaviors Checklist for Adolescents (IBCL-A) among 6,276 (67.7% girls) Chinese secondary school students. The IBCL-A included 15 maladaptive impulsive behaviors adapted from the Revised Diagnostic Interview for Borderlines. The authors obtained the severity and discrimination parameters for each item in the IBCL-A, examined differential item functioning across gender and age groups, and tested reliability and concurrent validity of the IBCL-A IRT-scaled score. Most items in the IBCL-A were the most accurate in assessing moderate to high levels of impulsivity and discriminated well among adolescents with varied levels of impulsivity. Differential item functioning emerged in several items across gender. The IRT-scaled score showed good construct validity and incremental predictive validity. Findings demonstrate the sound psychometric properties of the IBCL-A and support the clinical utility of this scale.     

Vocational aspirations of Chinese high school students and their parents' expectations

This study examined the vocational aspirations and parental vocational expectations of high school students and their parents (1067 parent–child dyads). Participants completed a demographic questionnaire and an Occupations List. The Occupations List consisted of 126 occupational titles evenly distributed across the six Holland types. Parents were asked to check the occupations that they expected their children to pursue and students were asked to select occupations to which they aspired. The expectations of parents were compared to the aspirations of children according to the occupational field, prestige, and sextype of occupations. The expectation–aspiration gap was relatively small for occupational field, but the gap was larger for occupational prestige and sextype. There were also gender differences for both expectations (parents' expectation toward sons and daughters) and aspirations (aspirations of male and female students). Types of high school (key or regular high schools) and parental educational background also related to expectations and aspirations. Theoretical, research, and practice implications are discussed.     

Contingent Punishment as a Double‐Edged Sword: A Dual‐Pathway Model from a Sense‐Making Perspective

A sense‐making perspective is adopted to explore how and when contingent punishment is related to job performance. Results from Study 1 support the prediction that contingent punishment is positively related to job performance through affective commitment and negatively related to job performance through self‐regulation impairment. Interpersonal justice on the part of supervisors strengthens the positive pathway, such that contingent punishment is more related to affective commitment when interpersonal justice is high. Core self‐evaluation of employees weakens the negative pathway, such that contingent punishment is less related to self‐regulation impairment when core self‐evaluation is high. Moderated mediation effects also show that the positive indirect effect of contingent punishment on job performance through affective commitment exists only when interpersonal justice is high and that the negative indirect effect of contingent punishment on job performance through self‐regulation impairment occurs only when core self‐evaluation is low. The results associated with the novel pathway mediated by self‐regulation impairment are replicated in Study 2.     

Can business and economics students perform elementary arithmetic?

Business and economics majors (N=146) were tested on the D'Amore Test of Elementary Arithmetic, which employs third-grade test items from 1932. Only 40% of the subjects passed the test by answering 10 out of 10 items correctly. Self-predicted scores were a good predictor of actual scores, but performance was not associated with demographic variables, grades in calculus courses, liking for science or computers, or mathematics anxiety. Scores decreased over the subjects' initial years on campus. The hardest test item, with an error rate of 23%, required the subject to evaluate (36 x 7) + (33 x 7). The results are similar to those of Standing in 2006, despite methodological changes intended to maximize performance.     

Somatoform dissociation in eating-disordered patients

This study investigated the role of somatoform dissociation in eating disorders and pathological eating behaviour, relative to the established association of eating pathology with psychological dissociation. The participants were 131 women with DSM-IV diagnoses of anorexic or bulimic disorders and 75 women who had no such disorder. Each woman completed measures of psychological and somatoform dissociation, as well as a measure of bulimic attitudes. The current presence or absence of specific bulimic behaviours was identified during the clinical interview. Levels of both forms of dissociation were higher in the women who had diagnoses of disorders with a bulimic component (bulimia nervosa; anorexia nervosa of the binge/purge subtype) than in the non-clinical or restrictive anorexic women. Somatoform dissociation showed particularly strong links with the presence of bulimic behavioural features (excessive exercise, laxative abuse, diet pill abuse, diuretic abuse) and with bulimic attitudes. The formulation and treatment of cases where there are bulimic features is likely to be enhanced by the assessment of somatoform dissociation.     

Vocational identity and career choice congruence of gifted and talented high school students

This study examined the career development of gifted high school juniorss in terms of vocational identity and congruence. The My Vo;cational Situation (MVS)was used to measure the career development of gifted high school ljuniors. Gender differences in vocational identity were found. Students who hasd tentative career and college major choices were found to have a higher level of vocational identity than those who did not have tentative choices. Measures of career choice congruence and college major choice congruence were obtained by examining the agreement between the Holland interest code and the tentative career and college major choices of participants. Gender differences were found o;n college major choice congruence, but not on career choice congruence. Vocational identity was related to college major choice congruence, but not to career choice congruence. Implications for counselling gifted students and research were discussed.     

Aspiring parents' and teachers' academic beliefs about young children

This study is an attempt to determine whether (a) the gender of a young child would elicit differential academic beliefs from individuals who aspire to become parents and teachers; and (b) male and female individuals who aspire to become parents and teachers have differential academic beliefs about young children. Data from 108 university students who intended to become parents and teachers showed that the gender of a young child elicited differential academic beliefs, and that male and female aspiring parents and teachers tended to have different academic beliefs about young children. The findings are discussed in terms of the relationship between stereotyped socialization practices and differential achievement between the two genders. Implications of the findings for education are noted.An earlier version of this paper was presented at the annual meeting of the Midwestern Educational Research Association in Chicago, Illinois, October 1988. The helpful comments of a review editor are most gratefully acknowledged.     

Maternal Beliefs,Adolescent Perceived Maternal Control and Psychological Competence in Poor Chinese Female-Headed Divorced Families

Based on the data of 337 female-headed divorced families living in poverty in Hong Kong, the relationships among maternal beliefs (Chinese cultural beliefs of familism, maternal expectations of children’s future, maternal attribute of children’s achievement to effort), adolescents’ perceived maternal control and adolescent psychological competence (indexed by beliefs in the future, clear and positive identity, and resilience) were examined. Results indicated that adolescents’ perceived maternal control mediated the influence between maternal beliefs and adolescent psychological competence in poor female-headed divorced families in Hong Kong. With the paucity of research on family beliefs and indigenous parenting practice, the present study underscores the importance of maternal beliefs and maternal control on nurturing adolescent psychological competence in Chinese divorced families facing adversity, which contributes to the development of Chinese familial model of resilience. Theoretical and practical implications of the findings are discussed.     

Posttraumatic Growth After Motor Vehicle Crashes

The relationship between sub-dimensions of posttraumatic growth (PTG) and distress was investigated for survivors of motor vehicle crashes (MVC). PTG and symptoms of posttraumatic stress disorder (PTSD) for 1045 MVC survivors who attended the Accident and Emergency Services were examined with the Chinese versions of the Posttraumatic Growth Inventory (PTGI) and the Impact of Event Scale-Revised 1 week after the experience of a MVC. A factor structure, which was different from both the original English version of the PTGI and the Chinese version of PTGI for cancer survivors, was identified. Factors extracted were: (1) Life and Self Appreciation; (2) New Commitments; (3) Enlightenment; and (4) Relating to Others. However, correlation analyses indicated a functional similarity between factors from this study and those from previous studies. Relations between PTG sub-dimensions and PTSD symptoms were identified. Results from hierarchical multiple regression analysis and structural equation modeling show that there were different predictors for different PTG sub-dimensions. Findings suggest that different modes of relationship between PTSD symptoms and PTG sub-dimensions may co-exist.
