Dual commitment to organization and supervisor: A person-centered approach

A recent trend in commitment research has been to use person-centered analytic strategies to identify homogeneous subgroups with varying configurations of commitment mindsets (affective, normative, continuance) or targets (e.g., organization, supervisor, team). A person-centered approach takes a more holistic perspective than the traditional variable-centered approach and can reflect potentially complex interactions among commitment mindsets and/or targets. We extend application of the person-centered approach to investigate profiles of commitment to two interrelated targets, the organization and supervisor, in two studies (Ns = 481 and 264) involving Belgian university graduates. Using latent profile analyses, we found that a similar 5-profile model fit best in both studies. The mindset pattern for the two targets was similar for some profile groups, but differed for others. The groups differed on perceived organizational and supervisory support and voluntary turnover largely as expected from commitment and support theory. Implications for future research and management practice are discussed.     

Procedural learning,consolidation, and transfer of a new skill in Developmental Coordination Disorder

The aim of this study was to explore the differences in procedural learning abilities between children with DCD and typically developing children by investigating the steps that lead to skill automatization (i.e., the stages of fast learning, consolidation, and slow learning). Transfer of the skill to a new situation was also assessed. We tested 34 children aged 6–12 years with and without DCD on a perceptuomotor adaptation task, a form of procedural learning that is thought to involve the cerebellum and the basal ganglia (regions whose impairment has been associated with DCD) but also other brain areas including frontal regions. The results showed similar rates of learning, consolidation, and transfer in DCD and control children. However, the DCD children's performance remained slower than that of controls throughout the procedural task and they reached a lower asymptotic performance level; the difficulties observed at the outset did not diminish with practice.     

Associations of Quality of Life,Physical Activity and Mood States in Women with Breast Cancer Treated with Curative Intent

This study aims to investigate the associations between quality of life, physical activity and mood states in women with breast cancer. A total of 354 women (mean age, 51.74?±?8.63 years; body mass index (BMI), 28?±?5.67 kg/m²) completed the Baecke Physical Activity Questionnaire, Profile of Mood States (POMS), European Organisation for Research and Treatment of Cancer Core Quality of Life Questionnaire (EORTC QLQ-C30) and European Organisation for Research and Treatment of Cancer Breast Cancer-Specific Quality of Life Questionnaire (EORTC QLQ-BR23). Pearson’s correlation and multiple linear regressions were used to verify the relations between outcomes and independent variables. Correlations between scores on POMS, Baecke Physical Activity Questionnaire and global health status/quality of life subscale of EORTC QLQ-C30 found associations (p?<?0.01) between physical activity (r?=?0.191), vigour (r?=?0.333) and fatigue (r?=??0.433). Multiple linear regression analysis of the global health status/quality of life subscale of the EORTC QLQ-C30 showed significant differences for vigour (p?<?0.001), social function (p?=?0.003), side effects of systemic therapy (p?=?0.019), arm and breast symptoms (p?<?0.001) and Baecke physical activity score (p?=?0.006). Physical activity is an independent factor related to the quality of life in women with breast cancer. Understanding these variables may influence clinical decisions during treatment and allow positive interventions regarding symptoms, functions and lifestyle.

God as Thou and Prayer as Dialogue: Martin Buber’s Tools for Reconciliation

??Prayer?? can be defined as ??the offering, in public worship or private devotion, of petition, confession, adoration, or thanksgiving to God; also the form of words in which such an offering is made?? (cf. Cohn-Sherbok 2010). In addition to this simple definition it could be said that there are different forms of prayer: some are vocal and articulate and others are only mental in nature; some prayers are communal and liturgical and other prayers are spontaneous or at least composed by the one saying the prayer (cf. Stump 1999). Accordingly, it is evident that there are manifold intricacies involved in any characterisation of ??prayer??. In this article my aims are twofold. First, I explore the implications of Martin Buber??s philosophy, particularly of his conception of God as Thou for our understanding of ??prayer??; second, I will argue that Buber??s understanding of ??prayer?? as dialogue serves as a way for the individual to seek reconciliation with itself, with others, and with God.     

Development of disruptive behaviors in young children: A prospective population‐based cohort study

We know relatively little about the development of disruptive behaviors (DBs), and gender differences therein. The objective of this study was to describe the continuity and discontinuity in the degree to which young children in the general population are reported to exhibit specific DBs over time. Data came from the Québec Longitudinal Study of Child Development. First, the results show that relatively few children exhibit DBs on a frequent basis at 41 months of age. Second, the results show that a majority of children who exhibit a particular DB on a frequent basis at 41 months of age did not do so 1 year earlier. In addition, a majority of children who exhibited a particular DB on a frequent basis at 29 months of age no longer do so 1 year later. Third, gender differences in DBs (boys > girls) are either emerging or at least increasing in magnitude between 29 and 41 months of age. Consistent with the canalization of the behavioral development principle, children who exhibited DBs on a frequent basis at 29 months of age are less likely to stop doing so in the following year if they had exhibited the same behaviors at 17 months of age.     

Forced treadmill exercise prevents oxidative stress and memory deficits following chronic cerebral hypoperfusion in the rat

Physical activity impacts functional recovery following stroke in humans, however its effects in experimental animals submitted to chronic cerebral hypoperfusion have not been investigated. The aim of this study was to evaluate the therapeutic potential of exercise, as assessed by cognitive activity in the Morris water maze and the brain oxidative status, through measurement of macromolecules damage, TBARS levels and total cellular thiols, as well as antioxidant enzymes in hippocampus, striatum and cerebral cortex. Adult male Wistar rats were submitted to the modified permanent bilateral occlusion of the common carotid arteries (2VO) method, with right common carotid artery being first occluded, and tested 3 months after the ischemic event. The effects of three different exercise protocols were examined: pre-ischemia, post-ischemia and pre+post-ischemia. Physical exercise consisted of sessions of 20-min, 3 times per week during 12 weeks (moderate intensity). Rats were submitted to cognitive assessment, in both reference and working spatial memory and after the last testing session were sacrificed to have oxidative stress parameters determined. Hypoperfusion caused a significant cognitive deficit in both spatial water maze tasks and this effect was reversed in rats receiving exercise protocol post and pre+post the ischemic event. Moreover, forced regular treadmill exercise regulated oxidative damage and antioxidant enzyme activity in the hippocampus. These results suggest that physical exercise protects against cognitive and biochemical impairments caused by chronic cerebral hypoperfusion.     

Implicit sequence learning in a continuous pursuit-tracking task

Assessing implicit learning in the continuous pursuit-tracking task usually concerns a repeated segment of target displacements masked by two random segments, as referred to as Pew’s paradigm. Evidence for segment learning in this paradigm is scanty and contrasts with robust sequence learning in discrete tracking tasks. The present study investigates this issue with two experiments in which participants (N = 56) performed a continuous tracking task. Contrary to Pew’s paradigm, participants were presented with a training sequence that was continuously cycled during 14 blocks of practice, but Block 12 in which a transfer sequence was introduced. Results demonstrate sequence learning in several conditions except in the condition that was obviously the most similar to previous studies failing to induce segment learning. Specifically, it is shown here that a target moving too slowly combined with variable time at which target reversal occurs prevents sequence learning. In addition, data from a post-experimental recognition test indicate that sequence learning was associated with explicit perceptual knowledge about the repetitive structure. We propose that learning repetition in a continuous tracking task is conditional on its capacity to (1) allow participants to detect the repeated regularities and (2) restrict feedback-based tracking strategies.
