Examining the differences between university students' levels of resilience on mindfulness, psychological distress and coping strategies
University students can face numerous stressors which can contribute to the development of psychological distress shown to be associated with decreasing completion and retention issues throughout Australian universities (Willcoxson, Cotter, & Joy, 2011). A positive predictor and outcome of successful student coping and adjustment to university and retention outcomes is resilience, the ability to cope in difficult situations and bounce back from adversity. Mindfulness has also been shown to be promote resilience. The present study examined differences in psychological distress, mindfulness, and coping strategies (adaptive vs. maladaptive) in university students (N = 122) with high and low levels of resilience. The results of a one-way MANOVA were consistent with hypotheses, revealing higher resilience scores were associated with greater mindfulness, higher adaptive coping scores, lower maladaptive coping, and reduced psychological distress. Students in the low resilience group were also found to have significantly lower levels of mindfulness, higher levels of psychological distress, reduced use of adaptive coping, and greater use of maladaptive coping, when compared to students with high resilience levels. Overall, findings of the current study are consistent with previous research and highlight the potential benefit of mindfulness-based coping interventions to foster resilience in university students

A Critical Examination of Sustainability Considerations in Yukon Environmental AssessmentâPast and Present
The Northern regions of Canada, as a result of landscape characteristics and political and cultural dynamics, present unique challenges and opportunities for meeting sustainability goals through environmental assessment (EA) processes. In order to understand the significance of the EA process in the North and its applicability to fulfilling sustainability goals, the past and present EA regimes of the Yukon are evaluated adopting a sustainability-focused framework. Unique changes to the Yukon EA process, as a result of land claim agreements and devolution have created innovative structures and processes, reflective of the environmental, socio-economic, cultural and political circumstances of the region. The evaluative framework was derived from EA and sustainability literature and supplemented by northern environmental management and sustainability considerations. Data collection methods included document reviews and 21 semi-structured interviews with informants familiar with past and present EA regimes of the Yukon. The findings highlight improvements to the Yukonâs EA regime over time, in terms of increased levels of accountability, greater consideration of northern sociocultural and ecological values, improved opportunities for participation and access to information and a greater recognition of First Nations values and role as decision makers. Yet weaknesses remain, such as the level of transparency at the decision making stage, the duplication of effort and lack of integration with other processes, and the failure to incorporate socio-economic mitigation measures. Considering that the Yukonâs EA system is one of the most recent EA processes in the country as well as in the north, its evaluation provides valuable insights into the initiatives and processes required for achieving sustainability within Northern EA regimes
Installation of insecticide-treated durable wall lining: evaluation of attachment materials and product durability under field conditions.
BACKGROUND: Insecticide-treated durable wall lining (DL) is a new method of vector control designed to supplement LLINs and overcome two inherent limitations of LLINs and IRS: nightly behavioural compliance and short residual activity, respectively. DL is a deltamethrin-treated polyethylene material, which when used to cover interior house walls, functions as long-lasting IRS. Because the DL concept anticipates minimal upkeep, a primary challenge is how to guarantee correct household installation and in situ longevity for several years. Field trials were undertaken on various wall surfaces in Ghana to identify a logistically feasible, durable and re-usable method for DL wall attachment and to pilot new methods for assessing DL durability. METHODS: Over fifty-five candidate attachment or fixing products, including mechanical fasteners, material anchors and adhesives, were evaluated for their ability to tolerate static loads (simulating long-term installation) and short-term heavy weights (imitating shock damage). Attachment products were also scored using qualitative logistical and feasibility criteria, including ease of preparation, grip of fixing to DL and possibility of re-use. RESULTS: The stress tests provided a standardised, reproducible and reliable system for assessing fixing effectiveness and DL durability, with 64% (14/22) of adhesives and 15% (2/13) of mechanical fasteners failing to meet the minimum requirements of attaching DL to mud walls for set time periods. For most fixings, less outward load (0.2-8.0 kg) was required to detach DL from the wall, compared to downward load (0.2-19.2 kg). Fixings were better able to grip DL onto concrete than clay surfaces. Using a plastic nail cap to increase DL attachment area greatly improved grip and outward load tolerance, more so than varying nail size, length or texture. CONCLUSIONS: Based on a series of systematic stress tests, optimized fixing products for polyethylene DL wall attachment were identified. In parallel, a detailed and adaptable method of DL household installation was developed for routine deployment in malaria endemic areas. These standardized stress tests will form the basis for comparative evaluations of new types of DL textile, which incorporate non-pyrethroid insecticides to control malaria transmitted by resistant mosquito populations

Bars, Nightclubs, and Cancer Prevention: New Approaches to Reduce Young Adult Cigarette Smoking.
IntroductionTobacco contributes to multiple cancers, and it is largely preventable. As overall smoking prevalence in California declines, smoking has become concentrated among high-risk groups. Targeting social/cultural groups (i.e., "peer crowds") that share common values, aspirations, and activities in social venues like bars and nightclubs may reach high-risk young adult smokers. Lack of population data on young adult peer crowds limits the ability to assess the potential reach of such interventions.MethodsThis multimodal population-based household survey included young adults residing in San Francisco and Alameda counties. Data were collected in 2014 and analyzed in 2016. Multivariable logistic regressions assessed smoking by sociodemographic factors, attitudes, self-rated health, peer crowd affiliation, and bar/nightclub attendance.ResultsSmoking prevalence was 15.1% overall; 35.3% of respondents sometimes or frequently attended bars. In controlled analyses, bar attendance (AOR=2.13, 95% CI=1.00, 4.53) and binge drinking (AOR=3.17, 95% CI=1.59, 6.32) were associated with greater odds of smoking, as was affiliation with "Hip Hop" (AOR=4.32, 95% CI=1.48, 12.67) and "Country" (AOR=3.13, 95% CI=1.21, 8.09) peer crowds. Multivariable models controlling for demographics estimated a high probability of smoking among bar patrons affiliating with Hip Hop (47%) and Country (52%) peer crowds.ConclusionsBar attendance and affiliation with certain peer crowds confers significantly higher smoking risk. Interventions targeting Hip Hop and Country peer crowds could efficiently reach smokers, and peer crowd-tailored interventions have been associated with decreased smoking and binge drinking. Targeted interventions in bars and nightclubs may be an efficient way to address these cancer risks
Living with a very low fat diet
Aims: This study investigated compliance with the very low fat diet used by some clinics in the UK to treat severe hypertriglyceridemia and the patientsâ experience of the diet. Methodology: Eight adults with severe hypertriglyceridemia attending the Lipid Clinic at Manchester Royal Infirmary, Manchester, UK took part in the study. Compliance with the therapeutic diet was assessed by analysis of telephone based diet histories and diet diaries using dietary assessment software. The patientsâ experience of the diet was investigated using telephone based semi-structured qualitative interviews and analysed using thematic analysis. Main findings: The diet histories revealed the mean percentage energy contribution from fat was 22.5%. This is significantly higher than the target of 15% prescribed by the very low fat diet. The qualitative interviews revealed that patients considered complete compliance difficult. The patients understood the health benefits of the diet. Their level of adherence was affected by their perception of vulnerability to the health consequences of non-adherence. Barriers to adherence included lack of accessible nutritional information, increased patient burden, lack of appropriate food choices, other peoplesâ ignorance with regard to the diet, lack of flavour and variety in the diet, a desire to broaden the palate, cost, social pressure to conform and negative experiences with dietitians. Enablers to compliance included nutritional awareness, desire to maintain good health, building on their nutritional knowledge base, behaviour and lifestyle modification, developing a routine, the support of family and friends and supportive eating environments. Conclusions: Compliance with the very low fat diet could be improved through extensive education on labelling, eating during special occasions such as Christmas, birthdays and eating out of home. Dietetic professionals need to work with food retailers and outlets to promote clear disclosure of the nutritional content of food to facilitate adherence to therapeutic diets
Rate-determining process in MISIM photocells for optoelectronic conversion using photo-induced pure polarization current without carrier transfer across interfaces
Recently, we proposed a [metal|insulator|semiconductor|insulator|metal] (MISIM) photocell, as a novel architecture for high-speed organic photodetectors. The electric polarization in the S layer, induced by modulated light illumination, propagates into the outside circuit as a polarization current through the I layers, without any carrier transfer across the interfaces. In the present work, we examined the MISIM photocells consisting of zinc-phthalocyanine(ZnPc)-C60 bilayers for the S layer and Parylene C for the two I layers, to understand the fundamental aspects of the MISIM photocells, such as current polarity and modulation-frequency dependence. It was found that, in such devices, the current polarity was primarily determined by the polarization in the S layer, which was induced by the donorâacceptor charge-transfer upon illumination. Furthermore, the ON and OFF current, which appeared in the periods of illumination-on and -off, respectively, exhibited significantly different dependence on the modulation frequency. This was well-explained by an imbalance between a quick polarization in the S layer during illumination and its slow relaxation in the dark
Design flexibility in cis-regulatory control of gene expression: synthetic and comparative evidence
In early Drosophila embryos, the transcription factor Dorsal regulates patterns of gene expression and cell fate specification along the dorsalâventral axis. How gene expression is produced within the broad lateral domain of the presumptive neurogenic ectoderm is not understood. To investigate transcriptional control during neurogenic ectoderm specification, we examined divergence and function of an embryonic cis-regulatory element controlling the gene short gastrulation (sog). While transcription factor binding sites are not completely conserved, we demonstrate that these sequences are bona fide regulatory elements, despite variable regulatory architecture. Mutation of conserved sequences revealed that putative transcription factor binding sites for Dorsal and Zelda, a ubiquitous maternal transcription factor, are required for proper sog expression. When Zelda and Dorsal sites are paired in a synthetic regulatory element, broad lateral expression results. However, synthetic regulatory elements that contain Dorsal and an additional activator also drive expression throughout the neurogenic ectoderm. Our results suggest that interaction between Dorsal and Zelda drives expression within the presumptive neurogenic ectoderm, but they also demonstrate that regulatory architecture directing expression in this domain is flexible. We propose a model for neurogenic ectoderm specification in which gene regulation occurs at the intersection of temporal and spatial transcription factor inputs
