Can markers detect contract cheating? Results from a pilot study

Contract cheating is the purchasing of custom-made university assignments with the intention of submitting them. Websites providing contract cheating services often claim this form of cheating is undetectable, and no published research has examined this claim. This paper documents a pilot study where markers were paid to mark a mixture of real student work and contract cheating assignments, to establish their accuracy at detecting contract cheating. Seven experienced markers individually blind marked the same bundle of 20 second-year psychology assignments, which included 6 that were purchased from contract cheating websites. Sensitivity analyses showed markers detected contract cheating 62% of the time. Specificity analyses showed markers correctly identified real student work 96% of the time. Our results contrast with contract cheating sites’ claims that contract cheating is undetectable. However, they should be taken with caution as they are from one course unit in one discipline.     

Evening electronic device use: The effects on alertness,sleep and next-day physical performance in athletes

The aim of the present study was to investigate the influence of different types of tasks performed with or without an electronic device (tablet) on pre-sleep alertness, subsequent sleep quality and next-day athletic performance. Eight highly trained netball players attended a sleep laboratory for pre-sleep testing, polysomnographic sleep monitoring and next-day physical performance testing on 5 separate occasions (1 familiarisation and 4 experimental sessions). For 2 h prior to bedtime, athletes completed cognitively stimulating tasks (puzzles) or passive tasks (reading) with or without a tablet. Sleepiness tended to be greater after reading compared to completing puzzles without a tablet (d = 0.80), but not with a tablet. Melatonin concentration increased more so after reading compared to completing puzzles on a tablet (P = 0.02). There were no significant differences in sleep quality or quantity or next-day athletic performance between any of the conditions. These data suggest that using a tablet for 2 h prior to sleep does not negatively affect subsequent sleep or next-day performance in athletes.     

Caffeine use in a Super Rugby game and its relationship to post-game sleep

Objective: To examine the relationship between regular game-related caffeine consumption on sleep after an evening Super Rugby game. Methods: Twenty elite rugby union players wore a wrist-activity monitor to measure sleep for three days before, three days after and on the night of an evening Super Rugby game (19:00–21:00). Players ingested caffeine as they would normally (i.e. before and sometimes during a game) and saliva samples were collected before (17:00) and after (21:30) the game for caffeine concentration. Results: Compared to the nights leading up to the game, on the night of the game, players went to bed 3?h later (23:08?±?66?min vs 02:11?±?114?min; p?p?p?p?p?p?=?.06) on game night. Conclusion: Caffeine consumption before a Super Rugby game markedly increases post-game saliva caffeine levels. This may contribute to the observed 3.5?h delay in time at sleep onset and the 1.5?h reduction in sleep duration on the night of the game. This study highlights the need for a strategic approach to the use of caffeine within a Super Rugby team considering the potential effect on post-game sleep.     

Identifying Food Safety Concerns When Communication Barriers Exist

Abstract: Students must be prepared to lead a diverse workforce. The objective of this study was to establish a teaching method that helps students identify barriers to food safety while working in a simulated environment with communication barriers. This study employed a perspective taking exercise based upon the principles of social learning theory. Students were randomly assigned as a “manager” or an “employee.” The managers were provided with a recipe and instructions in English and employees were provided with the recipe and instructions in an abstract, non‐English language. Students were instructed to prepare the recipe in silence using only nonverbal communication methods. Three teaching techniques were employed under this scenario to determine the most effective method of instruction. For the 1st method (Barrier Identification), students were asked to complete an open‐ended survey concerning their communication barriers in regards to food safety. Next (Modeling through Pictures), recipe books with pictures of each recipe with food safety icons were provided to half of the participants. In the 3rd scenario (Observation), students were videotaped to identify communication techniques and to identify common food safety violations. Lastly, a focus group was conducted, whereby students were required to reflect upon the experiment in order to identify specific food safety barriers. Students identified communication challenges to food safety and developed techniques to help overcome language barriers. However, the use of pictures did not increase the frequency of proper food handling procedures. This study found that a combination of gestures and demonstrations were the most valuable nonverbal forms of training.     

Thematic Analysis of Intergenerational Transmission of Trauma in Latinx Immigrant Families in the Southern US

Immigration is a growing social dynamic in many countries, eliciting a variety of different responses. Proponents of immigration note how the influx of new people into the United States (US) has enhanced the workforce and brought cultural enrichment; others have attributed to immigrants, particularly undocumented, a rise in crime and strains on social services. Consequently, immigrants often contend with discrimination and other unique stressors that increase the likelihood that immigration will be a traumatizing experience. Because scholarly focus on the impact of immigration upon psychological wellbeing typically highlights individual experiences, there is limited attention on the impact on immigrant families, particularly mixed-status families comprised of immigrant parents and children who are US citizens by birth. There is also limited attention on immigrant dynamics in the Southern US. This qualitative, thematic analysis explores the experiences of 71 pairs of Latinx immigrant mothers and their US citizen children, living in the Southern US, utilizing the lens of intergenerational transmission of trauma. Using narrative data taken from trauma assessment instruments, the authors identified the most prevalent themes shared by the mothers and their children as crime victimization, deportation, threats to family health, sexual abuse, and marital conflict.

     

Sand training: a review of current research and practical applications

Abstract

Sand surfaces can offer a higher energy cost (EC) and lower impact training stimulus compared with firmer and more traditional team sport training venues such as grass. This review aims to summarise the existing research on sand training, with a specific focus on its application as a team sports training venue. Compared with grass, significant physiological and biomechanical differences are associated with sand exercise. However, evidence also exists to suggest that training adaptations unique to sand can positively influence firm-ground performance. Furthermore, the lower impact forces experienced on sand can limit muscle damage, muscle soreness, and decrements in performance capacity relative to exercise intensity. Therefore, using a sand training surface in team sports may allow greater training adaptations to be achieved, while reducing performance decrements and injuries that may arise from heavy training. Nevertheless, further research should investigate the effect of sand surfaces over a greater range of training types and performance outcomes, to increase the application of sand training for team sports.
