Energizing respites from work: a randomized controlled study on respite interventions

Increasing and new work demands drain employees’ energy resources at work. This 4-week longitudinal field experiment investigated the energizing potential of a respite intervention conducted at the workplace (either a simulated savouring nature intervention or a progressive muscle relaxation intervention). First, growth modelling analyses confirmed a linear trend for the growth of vigour and decline in fatigue across the days of the intervention group, indicating a typical upward resource trajectory. No changes appeared in the control group. Mediation analyses indicated that repeatedly engaging in a daily respite intervention influenced more stable energy levels after the intervention period indirectly through the immediate changes in daily energy levels during the intervention period. Findings suggest that, in some cases, respite interventions may present a useful tool to replenish and build energy resources at work. Implications for using respite intervention in organizational research and practice are discussed.     

Foot and shoe responsible for majority of soft tissue work in early stance of walking

Soft tissues located throughout the human body are known to perform substantial mechanical work through wobbling and deforming, particularly following foot impacts with the ground. Yet, it is not known which specific tissues in the body are responsible for the majority of the soft tissue work. The purpose of this study was to quantify how much of the soft tissue work after foot contact was due to the foot and shoe, vs. from tissues elsewhere in the body, and how this distribution of work changed with walking speed and slope. We collected ground reaction forces and whole-body kinematics while ten subjects walked at five speeds (0.8–1.6 m/s) and on seven different slopes (9 degrees downhill to 9 degrees uphill). Using a previously-published Energy-Accounting analysis, we found that the majority of the soft tissue work during early stance was due to deformation of the foot and shoe. The percentage of work did not vary significantly with speed but did vary significantly with slope. The foot and shoe were responsible for ∼60–70% of the soft tissue work during level and uphill walking, and 80–90% during downhill walking.     

An attentional analysis of children's sensitivity to artistic style in paintings

This study investigated the claim that children are not able to judge artistic style when it conflicts with subject matter cues in paintings, using stimulus and methodological controls not employed previously. 6 and 9 year old children and adults were asked to judge which member of a pair of paintings looked like it was painted by the same painter as the target in a matching to sample task. Style choices were always possible and subject matter matches were either not possible because that dimension was controlled in the stimulus set (control), or possible but in conflict with style choices (experimental). The levels of discriminability of style and subject matter differences were varied. For control conditions, we found that performance was poor for all ages when style differences were low in discriminability and subject matter varied across the three stimuli; otherwise it was high. For experimental conditions, we found that irrelevant variation of subject matter was more detrimental if differences on that dimension were highly discriminable. Even the youngest children could make style matches and could do so even when a subject matter match was also possible, suggesting that they are sensitive to artistic style and can focus on that dimension in the face of irrelevant variation on other dimensions. The results are discussed as they relate to earlier claims that children are not able to judge artistic style and to the implications for training that follow from those claims.     

Dissociative Experiences Scale Taxon and Measurement of Dissociative Pathology: Does the Taxon Add to an Understanding of Dissociation and Its Associated Pathologies?

The Dissociative Experiences Scale Taxon (DES-T) is a modified version of the Dissociative Experiences Scale (DBS) that relies on a subset of eight categorical variables to overcome errors introduced into diagnostic classification by virtue of the use of dimensional measures of dissociation (e.g., DES) that mix normal and abnormal dissociative experiences. The present study examined the diagnostic accuracy of the DES-T and the DES in two non-dissociative psychiatric samples and four dissociative disorders. Classification of the six groups by the two measures yielded more errors with the DES-T and a high degree of correlation between normal and abnormal dissociative experience. The DES-T was sensitive for only the most extreme forms of dissociative pathology. There was no support for the use of the DES-T in lieu of the DES, or for reliance on either as a definitive diagnostic measure.     

Intervention Effects on Stage of Change Membership and Transitions among Adolescent Energy Balance Behaviors

The transition from childhood to adolescence is a crucial period for the development of healthy behaviors to be sustained later in life. With obesity a leading public health problem, the promotion of healthy behaviors has the potential to make a huge impact. The current study evaluated Stage of Change progression in a large (N = 4158) computer-delivered, Transtheoretical Model-tailored intervention focusing on physical activity and fruit and vegetable consumption (FV). Markov models were used to explore stage transitions and patterns of discrete change from sixth to ninth grade. Nested model comparisons examined the consistency of these patterns across time and intervention condition. Major findings supported models in which participants were free to transition forward and backward to any of the stages, but higher probabilities were observed for remaining in the same stage or for transitioning one or two stages forward. Participants in the intervention group had higher probabilities of transitioning toward Maintenance, with more change occurring relative to the comparison group during transitions from grades six to eight but not for grades eight to nine.     

On time and ready to go: An analysis of commuters’ punctuality and energy levels at work or school

The strain of the daily commute can negatively impact performance at work. This study differentiates how various modes influence commuters’ punctuality and energy levels at work and school. The data for this study come from the 2013 McGill Commuter Survey, a university-wide survey in which students, staff and faculty described their typical commuting experience to McGill University, located in Montreal, Canada. Ten multilevel mixed-effects logistic regressions are used to determine the factors that impact (1) a commuter’s feeling of being energized when he or she arrives at work or school and (2) his or her punctuality. Our results show that weather conditions and mode of transportation have significant impacts on an individual’s energy at work and punctuality. The models indicate that drivers have the lowest odds of feeling energized and the highest odds of arriving late for work. Cyclists, meanwhile, have the highest odds of feeling energized and being punctual. Overall, this study provides evidence that satisfaction with travel mode is associated with higher odds of feeling energized and being punctual. With these findings in mind, policy makers should consider developing strategies that aim to increase the mode satisfaction of commuters. Encouraging the habit of commuting by bicycle may also lead to improved performance at work or school.     

Relaxed Bodies,Emancipated Minds,and Dominant Calm

William James presented “The Gospel of Relaxation” (James in W. James, Writings 1878–1899, 1992) to the 1896 graduating class of Boston Normal School of Gymnastics and a decade later he delivered his presidential address “The Energies of Men” (James in W. James, Writings 1902–1910, 1987) to the American Philosophical Association. Both lectures focus on the body’s influence on emotions and on the liberating effects of live ideas on the body’s natural energies. They also reflect his use of the popular spiritual hygiene literature of his day to support his arguments. The first address draws on Hannah Whitall Smith’s views on disregarding our negative emotions and on Annie Payson Call’s writings, specifically her views on relaxation; the second on Horace Fletcher’s writings, specifically his views on anger and worry. I use these original sources to expand on key ideas in the two addresses, i.e., the role of imitation in altering unhealthy physiological habits and the energy-releasing role of suggestive ideas.

Pendular energy transduction in the different phases of gait cycle in post-stroke subjects

MainTo analyze spatiotemporal gait parameters and the body center of mass (CoM) energy transduction at self-selected speed walking in a group of older patients with stroke.MethodsA cross-sectional study, fifteen subjects with 4.06 years post ̵stroke hemiparesis (eleven men and four women) and fifteen healthy subjects (four men and eleven women) participate in this study. Pendulum-like determining variables; Recovery (R) and Congruity percentage (%Cong) were analyzed in addition to immediate pendular re-conversion (Rint) during the phases in which the gait cycle is usually divided in clinical evaluations.ResultsHealthy subjects walked faster that stroke group (p = 0.001). %Cong was significantly higher in post-stroke respect to healthy subjects (p = 0.05). Rint showed significant differences between the groups for all phases (p = 0.05). The relation between speed and R was confirmed, for healthy (r = 0.67, p = 0.006) and post-stroke subjects (r = 0.851, p = 0.001), %Cong y Rint (r = −0.79, p = 0.001), (r = −0.93, p = 0.001) and periods of double support (r = −0.76, p = 0.001), (r = 0.69, p = 0.004) respectively.ConclusionAlteration of pendular mechanism in subjects post-stroke is associated mainly with energy transduction; mechanical energy recovered during double support phases in healthy and post-stroke subjects follows a different trend, in post-stroke subjects, a longer duration of the double support is associated with less energy loss.
