Violence and Vigilance: The Acute Effects of Community Violent Crime on Sleep and Cortisol

The data combine objectively measured sleep and thrice‐daily salivary cortisol collected from a 4‐day diary study in a large Midwestern city with location data on all violent crimes recorded during the same time period for N = 82 children (M_age = 14.90, range = 11.27–18.11). The primary empirical strategy uses a within‐person design to measure the change in sleep and cortisol from the person's typical pattern on the night/day immediately following a local violent crime. On the night following a violent crime, children have later bedtimes. Children also have disrupted cortisol patterns the following morning. Supplementary analyses using varying distances of the crime to the child's home address confirm more proximate crimes correspond to later bedtimes.     

‘We’re not trying to turn them into middle-class Guardian readers’: constructing the offender in the probation ‘classroom’

Over the past 10 years, cognitive-behavioural programmes have come to be seen as a standard form of rehabilitation for offenders in the United Kingdom. However, the majority of research has tended to evaluate the programmes purely within the evidence-based context of the ‘What Works’ criminal justice agenda. By placing the programmes within their social and political context, this article suggests that they function as neo-liberal regimes of governance that aim to ‘responsibilise’ offenders. Through an analysis of interviews with probation practitioners, the article explores how ‘othering’ discourses relating to offenders intersected with gendered, classed and ‘raced’ social identities. Consequently, young white, working-class masculinities were constructed within this educational environment as impulsive, irresponsible and ‘cognitively deficient’. Thus, the article calls for a discursive shift away from cognitive-behavioural rehabilitation techniques and towards more genuinely inclusive, socially just, and holistic educational programmes for probationers.     

Time of day and short-duration high-intensity exercise influences on coagulation and fibrinolysis

Exercise has been demonstrated to have considerable effects upon haemostasis, with activation dependent upon the duration and intensity of the exercise bout. In addition, markers of coagulation and fibrinolysis have been shown to possess circadian rhythms, peaking within the morning (0600–1200?h). Therefore, the time of day in which exercise is performed may influence the activation of the coagulation and fibrinolytic systems. This study aimed to examine coagulation and fibrinolytic responses to short-duration high-intensity exercise when completed at different times of the day. Fifteen male cyclists (VO_2max: 60.3?±?8.1?ml?kg^?1?min^?1) completed a 4-km cycling time trial (TT) on five separate occasions at 0830, 1130, 1430, 1730 and 2030. Venous blood samples were obtained pre- and immediately post-exercise, and analysed for tissue factor (TF), tissue factor pathway inhibitor (TFPI), thrombin–anti-thrombin complexes (TAT) and D-Dimer. Exercise significantly increased plasma concentrations of TF (p?p?p?p?p?=?.004) and TFPI (p?=?.031), with 0830 greater than 1730 (p .001), while 1730 was less than 2030?h (p?=?.008), respectively. There was no significant effect of time of day for TAT (p?=?.364) and D-Dimer (p?=?.228). Power output, TT time and heart rate were not significantly different between TTs (p?>?.05); however, percentage VO_2max was greater at 1730 when compared to 2030 (p?=?.04). Due to a time-of-day effect present within TF, peaking at 0830, caution should be applied when prescribing short-duration high-intensity exercise bout within the morning in populations predisposed to hypercoagulability.     

A reciprocal effects model of the temporal ordering of motivation and burnout among youth table tennis players in intensive training settings

Abstract

Using self-determination theory (SDT) (Deci, E.L., & Ryan, R.M. (1985). Intrinsic motivation and self-determination in human behavior. New York, NY: Plenum) as the theoretical framework, we conducted a longitudinal investigation of the temporal ordering between motivation and burnout among youth athletes in intensive training setting. Data were collected from 145 table tennis players in intensive training centres at three time points during a 2-month period characterised by a simultaneous increase in social, physical and psychological demands for these athletes. Structural equation modelling of cross-lagged panel models was used to test the hypotheses. Results showed significant paths leading from athlete burnout – especially sport devaluation and reduced sense of accomplishment – at time 1 to amotivation, intrinsic and extrinsic motivations at times 2 and 3. Only two significant paths leading from motivation (introjected regulation at time 1) to burnout (emotional/physical exhaustion at time 2 and reduced sense of accomplishment at time 3) were identified. Overall, our results suggest that athlete burnout predicts motivation over time but motivation did not predict athlete burnout over time. Results are discussed in terms of current research findings on SDT.     

Twitter,Team GB and the Australian Olympic Team: representations of gender in social media spaces

Twitter is used by athletes, sporting teams and sports media to provide updates on the results of sporting events as they happen. Unlike traditional forms of sports media, online sports media offers the potential for diverse representations of athletes. The current study examined gender in social media coverage of the 2016 Olympic Games using a third wave feminist lens. The analysis focused on the Twitter pages of ‘Team GB’ and the ‘Australian Olympic team’ and the sports stories and images posted during the Rio Olympic Games. Despite a number of traditional differences in the ways that male and females were represented being present, such as the presence of ‘active’ images of male athletes accompanying sports stories and the presence of infantalization in the language used to represent female performers, this analysis demonstrated significant strides forward in terms of the quantity of coverage received by women in online spaces. It further highlights virtual platforms as dynamic spaces for the representation of women athletes.     

Physiological load associated with a Zumba® fitness workout: a comparison pilot study between classes and a DVD

The objectives were to compare the metabolic load elicited by Zumba^® classes and DVD workouts and link the physiological responses to participants’ psychological characteristics. Fifteen women (25.4 ± 4.3 years old; 164.9 ± 5.1 cm; 56.9 ± 5.8 kg; 23.9 ± 4.9% body fat) performed three Zumba^® classes and three Zumba^® DVD workouts using a repeated measure design. Energy expenditure was assessed by extrapolating oxygen cost from heart rate (HR) using regressions from a preliminary incremental running test. Differences between Zumba^® classes and Zumba^® DVD workouts were assessed by Student’s T tests and repeated measures analysis of variance and correlations between physiological and psychological variables by the Pearson’s coefficient. Results showed that Zumba^® classes allowed greater energy expenditure compared to Zumba^® DVD workouts (6.8 ± 0.9 vs 5.6 ± 0.9 kcal · min^?1, 95% confidence interval (CI) limits: 0.3–2.1, P = 0.016), with significant differences in the time spent with a HR above 85% of HR reserve (14.7 vs 1.7%, 95% CI: 5.6–20.4, P = 0.021). Furthermore, women with a greater autonomy score showed a smaller difference between DVD and class (r = 0.511, P = 0.048), while greater differences were shown in women with greater interpersonal skills (r = ?0.563, P = 0.028). The results suggest that while both types of workouts are suitable to maintain fitness Zumba^® classes allow greater energy expenditure.     

Adopted and permanently placed children in education: from rainbows to reality

Children who leave care into adoption and special guardianship are often considered by schools and local authorities to have found their “happy ending.” Yet there is growing evidence that the impact of prenatal and early trauma, abuse and neglect does not disappear upon placement in a permanent family. Rates of social, emotional and mental health difficulties remain high, and the group has pronounced educational needs. Whilst having high levels of involvement with education and health services, families report significant difficulties in mobilising understanding, support and provision. In the context of growing numbers of children in England finding permanence through adoption and special guardianship, and the Department for Education’s increasing focus on addressing the needs of this group, this paper highlights the key role of Educational Psychology Services in supporting adopted and other permanently placed children by providing training, consultation, assessment, intervention and research for children and their families, their schools, and the local authorities.     

Has Motivational Interviewing Fallen into its Own Premature Focus Trap?

Since the initial conception of the behaviour change method Motivational Interviewing, there has been a shift evident in epistemological, methodological and practical applications, from an inductive, process and practitioner-focussed approach to that which is more deductive, research-outcome, and confirmatory-focussed. This paper highlights the conceptual and practical problems of adopting this approach, including the consequences of assessing the what (deductive outcome-focussed) at the expense of the how (inductively process-focussed). We encourage a return to an inductive, practitioner and client-focussed MI approach and propose the use of Computer Assisted Qualitative Data Analysis Systems such as NVivo in research initiatives to support this aim.
