Abstract Nightwork is associated with fatigue, decreased sleep quality, and impairments in cognitive function. While attentional tasks have been widely investigated, there are limited data on more complex tasks, such as executive functioning during nightwork. Workers often need to rapidly shift between tasks, adapting to new and complex situations. The aim of this study was to investigate the impact of nightwork on executive functioning. Healthy, non-shift working individuals (N=8; 5F, 24.8±5.0y) participated in a 7-day live-in laboratory study. Participants underwent an 8h TIB baseline sleep, followed by 4 consecutive simulated nightshifts with 7h TIB sleep during the day and an 8h TIB recovery sleep. Participants were assessed for executive function at 2000h, 2200h, 0100h and 0400h. Executive functioning was assessed with a mental flexibility switching task where a 3D rotation and math task were displayed simultaneously with an arrow indicating which task to complete in a random order. Resulting throughput data were analysed using linear mixed models. There was a main effect of time of night (F(3,77)=4.81,p=.004) on throughput such that there was a speed accuracy trade off over the night shift with slower switching ability later in the shift. There was also a main effect of nightshift (F(2,77)=54.33,p<.001) where participants’ performance improved on the task with each nightshift. This study suggests executive functioning is impaired on nightshift with worse performance at 0400h. Task improvements over consecutive nightshifts may have been due to learning or acclimation to nightwork. Understanding complex task performance on nightshift is important for tailoring countermeasures.

Abstract. Neurocognitive deficits in patients with mental disorders are partially due to secondary influences. “Stereotype threat” denotes the phenomenon that performance is compromised when a participant is confronted with a devaluing stereotype. The present study examined the impact of stereotype threat on neuropsychological performance in schizophrenia. Seventy-seven participants with a self-reported diagnosis of schizophrenia were randomly assigned to either an experimental condition involving stereotype threat activation or a control condition in an online study. Participants completed memory and attention tests as well as questionnaires on motivation, self-efficacy expectations, cognitive complaints, and self-stigmatization. Contrary to our prediction, the two groups showed no significant differences regarding neuropsychological performance and self-report measures. Limitations, such as a possibly too weak threat cue, are discussed and recommendations for future studies are outlined.

The Impact

The present research examines the social value attributed to endorsing the belief in a just world for self (BJW-S) and for others (BJW-O) in a Western society. We conducted four studies in which we asked participants to assess a target who endorsed BJW-S vs. BJW-O either strongly or weakly. Results showed that endorsement of BJW-S was socially valued and had a greater effect on social utility judgments than it did on social desirability judgments. In contrast, the main effect of endorsement of BJW-O was to reduce the target’s social desirability. The results also showed that the effect of BJW-S on social utility is mediated by the target’s perceived individualism, whereas the effect of BJW-S and BJW-O on social desirability is mediated by the target’s perceived collectivism.

The Impact

The paper considers techniques to develop a mathematical model using a method of «parallel compressors». The model is intended to estimate the impact of the air inlet distortion on the primary parameters of the aero-engine.  The paper presents rated estimation results in the context of twin spool turbofan design for two typical cruiser modes of flight of the supersonic passenger jet. In estimation the base values σbase and the average values of the inlet ram recovery σave remained invariable. Thus, parametrical calculations were performed for each chosen relative value of the area of low-pressure region.The paper shows that an impact degree of the inlet distortion on the engine thrust for two modes under consideration is essentially different. In other words, if in the subsonic mode the impact assessment can be confined only to taking into account the influence of decreasing average values of the inlet total pressure, the use of such an assumption in the supersonic cruiser mode may result in considerable errors.With invariable values of the pressure recovery factor at the engine intake, which correspond to the speed of flight for a typical air inlet of external compression σbase, and average value σave, a parameter Δσuneven  has the main effect on the engine thrust, and degree of this effect essentially depends on a difference between σave and σbase values.

The outbreak of the COVID-19 pandemic caused a number of changes in social life around the world. In response to the growing number of infections, some countries have introduced restrictions that may have resulted in the change of the lifestyle. The aim of our study was to investigate the impact of the lockdown on body weight, physical activity and some eating habits of the society. The survey involving 183 people was conducted using a proprietary questionnaire. The mean age of the study participants was 33 ± 11 and mean height 169 ± 8 cm. An average increase in body weight was observed in 49.18% by 0.63 ± 3.7 kg which was the result of a decrease in physical activity and an increase in food consumption. We also observed a decrease in PAL from 1.64 ± 0.15 to 1.58 ± 0.13 and changes in the amount of food and individual groups of products consumption, including alcohol. Among the study participants who did not lose body mass, there was an average weight gain of 2.25 ± 2.5 kg. In conclusion, an increase of weight was shown in about half of the respondents in the study group which was associated with a decrease in physical activity and an increase in the consumption of total food and high energy density products.

While many facets of loneliness have been explored, research examining the efficacy of loneliness interventions has been overlooked among young adults. The study of loneliness among young adults has become increasingly important considering the current state of isolation and stay-at-home orders issued to prevent the spread of COVID-19. Preliminary reports suggest an increase in loneliness as a result of the current health pandemic, especially among young adults, who have reported feeling lonelier than any other age group. Such findings warrant the study of ways to help reduce loneliness among young adults. The current study examined the efficacy of strategies that might be used to help young adults manage feelings of loneliness. Two hundred and seventy-eight young adults completed the study. Participants read one of four messages: mindfulness, social cognitions, coping behaviors, or a control. Participants in the mindfulness condition felt better equipped to manage future instances of loneliness and held better attitudes toward this intervention. The current research helps to advance understanding of effective ways of helping young adults cope with loneliness.

The study aimed to describe views on Voluntary Assisted Dying (VAD), gleaned through qualitative analysis of participant responses to a set activity, run during the 2018 ‘Dying2Learn’ Massive Open Online Course (MOOC). Data from 508 participants, most of whom identified as health professionals, were analysed using thematic content analysis, and themes generated. A large proportion of participants discussed their personal views related to VAD, specifically around choice, control, dignity, palliative care and dying at home, medical intervention, societal factors, the impact on those left behind, laws and regulations, dying ‘naturally’, advance care directives, and being in pain. In this study, participants had many different views on the act itself, often divisive, but also with common concepts such as respecting the choices and decisions of others.

Abstract Introduction The purpose of the current study was to examine the relationship between current beliefs about hypnotic medications and historical use of prescription hypnotic medications or non-prescription substances for sleep (i.e., over the counter [OTC] medications, alcohol, and cannabis). Methods Participants were 142 middle age and older adults with insomnia (M age = 62.9 [SD = 8.1]; 71.1% female) enrolled in the RCT of the Effectiveness of Stepped-Care Sleep Therapy In General Practice (RESTING) study. Participants reported on history of substances they have tried for insomnia and completed the Beliefs about Medications Questionnaire-Specific with two subscales assessing beliefs about 1) the necessity for hypnotics, and 2) concerns about potential adverse consequences of hypnotics. Participants were grouped based on whether they had used no substances for sleep (No Subs, 11.6%), only prescription medications (Rx Only, 9.5%), only non-prescription substances (NonRx Only, 26.6%), or both prescription and non-prescription substances (Both, 52.3%). Results Sixty-one percent of the sample had used prescription medication for sleep and 79% had used non-prescription substances (74% OTC medication, 23% alcohol, 34% cannabis). The greater number of historical substances endorsed, the stronger the beliefs about necessity of hypnotics, F(1,140)=23.3, p<.001, but not about concerns. Substance groups differed significantly on necessity beliefs, F(3,1)=10.68, p<.001; post-hocs revealed the Both group had stronger beliefs than the No and NonRx Only groups. Substance groups also differed significantly on the concerns subscale, F(3,1)=6.68, p<.001; post-hocs revealed the NonRx Only group had stronger harm beliefs than the other three groups. Conclusion The majority of the sample had used both prescription and non-prescription substances to treat insomnia. Historical use of substances for treating insomnia was associated with current beliefs about hypnotics. Individuals who had used both prescription and non-prescription substances for sleep in the past had stronger beliefs about needing hypnotics to sleep at present, which may reflect a pattern of multiple treatment failures. Individuals who had only tried non-prescription substances for sleep may have specifically sought alternative substances due to concerns about using hypnotics. Future research should seek to understand the impact of treatment history on engagement in and benefit from non-medication-based treatment for insomnia.

The Impact

Sharing individualized results with health study participants, a practice we and others refer to as “report-back,” ensures participant access to exposure and health information and may promote health equity. However, the practice of report-back and the content shared is often limited by the time-intensive process of personalizing reports. Software tools that automate creation of individualized reports have been built for specific studies, but are largely not open-source or broadly modifiable. We created an open-source and generalizable tool, called the Macro for the Compilation of Report-backs (MCR), to automate compilation of health study reports. We piloted MCR in two environmental exposure studies in Massachusetts, USA, and interviewed research team members (n = 7) about the impact of MCR on the report-back process. Researchers using MCR created more detailed reports than during manual report-back, including more individualized numerical, text, and graphical results. Using MCR, researchers saved time producing draft and final reports. Researchers also reported feeling more creative in the design process and more confident in report-back quality control. While MCR does not expedite the entire report-back process, we hope that this open-source tool reduces the barriers to personalizing health study reports, promotes more equitable access to individualized data, and advances self-determination among participants.
