Job Conditions and Wellness/Health Outcomes in Dutch Secondary School Teachers

The aim of the present study is to compare the work situation of Dutch secondary school teachers to job conditions of European teachers and to test the Job Demand-Control-Social Support model (JDCS model, Karasek and Theorell, <citeref rid="bib24">1990</citeref>) on burnout, job satisfaction and somatic symptoms. The Dutch data (N = 304) were gathered in seven secondary schools from across the country. The remaining European group consisted of 1878 upper secondary school teachers originating from 10 countries. Additive and interactive effects in the JDCS model could be identified for emotional exhaustion only. Furthermore, a curvilinear (U-shaped) relationship was found between control and emotional exhaustion. In addition to the JDCS model, the contribution of coping in the explanation of the outcomes was tested. Attempts have been made to deal with criticisms, which are frequently leveled at the implementation of the JDCS model. Dutch teachers do not differ on job conditions from the European sample except for two working conditions where the Dutch indicate less physical exertion and environmental risks than the European reference sample. The Dutch report lower levels of coping than the reference group, they are more depersonalised and are less satisfied than teachers of the European reference group. On the other hand, the Dutch teachers had fewer somatic complaints and reported higher levels of personal accomplishment than their European colleagues.     

Which modality is best for presenting navigation instructions?

Three experiments involved college students receiving and following instructions of various lengths for navigating in a three-dimensional space displayed on a computer screen. The purpose was to evaluate which is the best modality for presenting navigation instructions so that they can be executed successfully. Single modalities (read, hear, and see) were considered along with dual modalities presented simultaneously or successively. It was found that when there were differences between single modalities, generally execution accuracy was best for see and worst for read. Information presented in two modalities did not yield better accuracy than information presented twice in a single modality. Also, the ordering of modalities depended on the extent of practice. Thus, presentation modality does not have a consistently large effect on receiving and following navigation instructions. Repetition and the amount of practice are much more important variables than is presentation modality in determining how well navigation instructions are followed.     

Gender responses to psychological distress among Palestinians: Risk and protective factors

This study investigated the extent to which differences in the presence of trauma, political and normative stressors, resources, coping, and hardiness could account for variation in gender responses to psychological distress among Palestinians. Participants were 624 males and females aged 27–56 years. Questionnaires were administered in an interview format with participants at home. Results indicated that female gender has been associated with psychological distress. The females in this study reported feeling distressed by intrafamily strains, whereas males reported feeling distressed by work and family strains as well as losses. Political stressors were more predictive of psychological distress than was the presence of trauma or normative stressors. The sociodemographics had different patterns of relations with psychological distress. Females' education was negatively related to psychological distress, whereas the family income was negatively related to psychological distress in males. No significant differences between males and females were found in their coping responses. However, cognitive and behavioural strategies Family Crisis Oriented Personal Evaluation Scales (F‐COPES) seem to combine and had an impact on psychological distress of females only. Also, family hardiness was evidenced to have an influence on perceived psychological distress in both genders. The clinical and policy implications of these conclusions were discussed.     

Identity and the Theory of Planned Behavior: Predicting Maintenance of Volunteering After Three Years

Is identity an important predictor of social behavior? The present longitudinal study is focused on identity in order to understand why people continue to volunteer over an extended period of time. The theory of planned behavior and the role identity model of volunteering are used as theoretical framework. Two hundred thirty Italian volunteers were sampled and followed for 3 years. We analyzed functions of role identity as a volunteer. Results showed a significant impact of role identity in predicting volunteer performance after 3 years, mediated through behavioral intentions. Role identity fully mediated the relationships between behavioral intention and attitude, social norms, past behavior and parental modelling.     

Cognitive and neural determinants of response strategy in the dual-solution plus-maze task

Response strategy in the dual-solution plus maze is regarded as a form of stimulus-response learning. In this study, by using an outcome devaluation procedure, we show that it can be based on both action-outcome and stimulus-response habit learning, depending on the amount of training that the animals receive. Furthermore, we show that deactivation of the dorso-medial and the dorso-lateral striatum with Botulinum neurotoxin A, mimicked or abolished, respectively, the effects of practice on the sensitivity of the response strategy to outcome devaluation. These findings have relevant implications for the understanding of the learning mechanisms underlying different overt behaviors in this widely used maze task.     

A randomized experiment comparing random and cutoff-based assignment

In this article, we review past studies comparing randomized experiments to regression discontinuity designs, mostly finding similar results, but with significant exceptions. The latter might be due to potential confounds of study characteristics with assignment method or with failure to estimate the same parameter over methods. In this study, we correct the problems by randomly assigning 588 participants to be in a randomized experiment or a regression discontinuity design in which they are otherwise treated identically, comparing results estimating both the same and different parameters. Analysis includes parametric, semiparametric, and nonparametric methods of modeling nonlinearities. Results suggest that estimates from regression discontinuity designs approximate the results of randomized experiments reasonably well but also raise the issue of what constitutes agreement between the 2 estimates.     

A multilevel study on the relationships between work characteristics, self-efficacy, collective efficacy, and organizational citizenship behavior: the case of Taiwanese police duty-executing organizations

Public security, traffic management, and service for the people are the 3 major functions of policing in Taiwan. This definition encompasses not only the traditional job characteristics, but also the level of contextual characteristics and social characteristics because of police work's characteristics and its frequent interaction with the public. Thus, the present study conducted a multilevel model analysis by taking self-efficacy and collective efficacy as the mediating variables. The purpose was to investigate the influences of motivational work characteristics (knowledge-oriented) and social work characteristics (socially and contextually oriented) of work-design model on the police officers' organizational citizenship behavior (OCB), by using first-line police officers in Taiwan as the research objects. The study showed not only that knowledge characteristics will influence the self-efficacy of a police officer and that self-efficacy can in turn influence individual police officers' OCB, but also the contextual effect of social characteristics, contextual characteristics, and collective efficacy on self-efficacy and individuals' OCB. Additionally, there was a crosslevel moderating effect from contextual characteristics on the relationship between knowledge characteristics and self-efficacy and the relationship between self-efficacy and the individuals' OCB. The authors conclude the article with research implications.     

Basic numerical capacities and prevalence of developmental dyscalculia: the Havana Survey

The association of enumeration and number comparison capacities with arithmetical competence was examined in a large sample of children from 2nd to 9th grades. It was found that efficiency on numerical capacities predicted separately more than 25% of the variance in the individual differences on a timed arithmetical test, and this occurred for both younger and older learners. These capacities were also significant predictors of individual variations in an untimed curriculum-based math achievement test and on the teacher scores of math performance over developmental time. Based on these findings, these numerical capacities were used for estimating the prevalence and gender ratio of basic numerical deficits and developmental dyscalculia (DD) over the grade range defined above (N = 11,652 children). The extent to which DD affects the population with poor ability on calculation was also examined. For this purpose, the prevalence and gender ratio of arithmetical dysfluency (AD) were estimated in the same cohort. The estimated prevalence of DD was 3.4%, and the male:female ratio was 4:1. However, the prevalence of AD was almost 3 times as high (9.35%), and no gender differences were found (male:female ratio = 1.07:1). Basic numerical deficits affect 4.54% of school-age population and affect more boys than girls (2.4:1). The differences between the corresponding estimates were highly significant (α < .01). Based on these contrastive findings, it is concluded that DD, defined as a defective sense of numerosity, could be a distinctive disorder that affects only a portion of children with AD.
