Take a break! Benefits of sleep and short breaks for daily work engagement

The current study investigates the benefits of a good night’s sleep and short work breaks for employees’ daily work engagement. It is hypothesized that sleep and self-initiated short breaks help restore energetic and self-regulatory resources which, in turn, enable employees to experience high work engagement. A daily diary study was conducted with 107 employees who provided data twice a day (before lunch and at the end of the working day) over 5 workdays (453 days in total). Multilevel regression analyses showed that sleep quality and short breaks were beneficial for employees’ daily work engagement. After nights employees slept better, they indicated higher work engagement during the day. Moreover, taking self-initiated short breaks from work in the afternoon boosted daily work engagement, whereas taking short breaks in the morning failed to predict daily work engagement. Taking short breaks did not compensate for impaired sleep with regard to daily work engagement. Overall, these findings suggest that recovery before and during work can foster employees’ daily work engagement.     

Exploration of likely engagement with Monetary Contingency Contracts for weight loss: a questionnaire study

Monetary Contingency Contracts (MCCs) are schemes that ask individuals to pledge money that is returned contingent on behaviour change. In relation to weight loss, this study explored likely levels of engagement with MCCs, how much individuals would be willing to pay into an MCC, and how these amounts vary under different contract conditions. Fifty-six individuals with BMI above 25 who were motivated to lose weight were recruited. The majority of participants (87.5%) indicated that they would be willing to engage with weight loss MCCs, but showed more reluctance to subscribe to pair-based MCCs which offered; (a) refunds contingent on the weight loss of a weight loss partner, and (b) ‘all or nothing refunds’ in which no reward is given for any weight loss below the target weight loss goal. This study provides preliminary evidence that individuals motivated to lose weight may be willing to engage with weight loss MCCs. Further research is needed to explore reasons for reluctance to subscribe to MCCs with certain conditions, to inform the design of future experimental studies testing the efficacy of MCCs as part of an intervention for weight loss.     

Narrow lanes and their effect on drivers’ behaviour at motorway roadworks

In recent years, more use of narrow lanes as a temporary traffic management scheme (TTMS) on UK motorway roadwork sections has been made. The rationale is to free up carriageway space, especially for sites with high traffic demands needing repairs. What remains to be determined is the impact of this work on traffic operation. This is important due to the need to manage traffic operational turbulence which could affect the capacity as well as safety levels in roadwork sections. Site observations (mainly using camcorders from overhead bridges) were made which uncovered two discernible patterns of driving behaviour where narrow lanes are implemented at roadworks, especially when heavy goods vehicles (HGVs) are present: (i) “avoiding” passing/overtaking HGVs travelling in the adjacent lanes and (ii) lane “repositioning” while passing/overtaking which might cause some turbulence to traffic operation. From one site, almost half of the passenger car drivers (including small vans) who were following a HGV on the adjacent lanes were avoiding passing that HGV. Also, nearly three quarters of the observed passenger cars, the passenger car drivers tried to position their vehicles as far away as possible, laterally, from the adjacent HGV while passing/overtaking that HGV in order to widen the lateral gap between their vehicles and the HGV. This resulted in driving too close to the edge of the road markings of their current lane away from the HGV. Therefore, this paper aims to report on the “avoiding” and lane “repositioning” behaviours to help inform traffic management teams/designers using narrow lanes as TTMS and make them aware of such behaviours (especially for motorway sections carrying high percentages of HGVs). Also, the finding from these observations were used in the development of a new micro-simulation model in order to evaluate the effect of such turbulence.     

Workplace diversity in South Africa: Its qualities and management

This qualitative study explored diversity management strategies used by South African financial institutions. The sample included 72 employees (33.33% females; 39.08% Indigenous African language speakers). Of the participants, 44.45% were white, 28.57% were black, 22.22% were Indian, and 4.78% were from the Coloured population group. The participants completed focus-group interviews or individual interviews on their workplace diversity experiences and its management. Themes emerging from Atlas.ti and Tesch’s data analyses included the consensus view that effective diversity management proactively addressed cultural differences, stereotyping, prejudice, discrimination, misunderstandings, communication gaps, and conflict due to organisational hierarchical levels. Organisational competitiveness is enhanced through client focused services and an employee valuing work environment. However, some of the employees also viewed diversity initiatives as costly, time-consuming, and forced on employees.     

Stress Management for College Students: An Experiential Multi-Modal Approach

This quasi-experimental study evaluated the effectiveness of a multi-modal experiential stress management course for college students. Experiential approaches included yoga, mindfulness hiking, and equine-assisted stress management activities. Univariate analysis of covariance revealed significantly lower perceived stress for the experimental group at the conclusion of the stress management course. Repeated measures univariate analysis of variance revealed that the stress management course significantly reduced present moment stress over time and that equine-assisted activities were as effective as yoga and mindfulness hiking in reducing student stress.

Causal judgments about empirical information in an interrupted time series design

Empirical information available for causal judgment in everyday life tends to take the form of quasi-experimental designs, lacking control groups, more than the form of contingency information that is usually presented in experiments. Stimuli were presented in which values of an outcome variable for a single individual were recorded over six time periods, and an intervention was introduced between the fifth and sixth time periods. Participants judged whether and how much the intervention affected the outcome. With numerical stimulus information, judgments were higher for a pre-intervention profile in which all values were the same than for pre-intervention profiles with any other kind of trend. With graphical stimulus information, judgments were more sensitive to trends, tending to be higher when an increase after the intervention was preceded by a decreasing series than when it was preceded by an increasing series ending on the same value at the fifth time period. It is suggested that a feature-analytic model, in which the salience of different features of information varies between presentation formats, may provide the best prospect of explaining the results.     

Understanding maladaptive responses to rejection: Aggression with an audience

Logically, responding aggressively to rejection is maladaptive because one is unlikely to seek a relationship with an aggressor. We predict that when concealed, the illogical aggressive response to rejection is more likely, whereas when the rejected individuals’ aggressive responses are perceived as public, the aggressive acts may be reduced. Participants were rejected by others (Experiment 1) or were either accepted or rejected during an online ball-tossing game (Experiment 2) and were then given an opportunity to aggress publicly or privately. Across experiments, when the opportunity to aggress was made public, rejected participants exhibited less aggressive behavior. When concerned about the perception of their public aggressive responses by others, rejected individuals’ aggressive responses diminished compared with those whose actions were private. Crucially, this extended to aggression visible only to neutral others, suggesting that effects cannot solely be due to fear of retribution.     

Does contingency in adults’ responding influence 12-month-old infants’ social referencing?

In two experiments we examined the influence of contingent versus non-contingent responding on infant social referencing behavior. EXPERIMENT 1: Forty 12-month-old infants were exposed to an ambiguous toy in a social referencing situation. In one condition an unfamiliar adult who in a previous play situation had responded contingently to the infant’s looks gave the infant positive information about the toy. In the other condition an unfamiliar adult who previously had not responded contingently delivered the positive information. EXPERIMENT 2: Forty-eight 12-month-old infants participated in Experiment 2. In this experiment it was examined whether the familiarity of the adult influences infants’ reactions to contingency in responding. In one condition a parent who previously had responded contingently to the infant’s looks provided positive information about the ambiguous toy, and in the other condition a parent who previously had not responded contingently provided the positive information. The infants looked more at the contingent experimenter in Experimenter 1, and also played more with the toy after receiving positive information from the contingent experimenter. No differences in looking at the parent and in playing with the toy were found in Experiment 2. The results indicate that contingency in responding, as well as the familiarity of the adult, influence infants’ social referencing behavior.
