Ageing, depression, anxiety, social support and the diurnal rhythm and awakening response of salivary cortisol

The present study compared the cortisol awakening response and diurnal rhythm in 24 young healthy students and 48 community-dwelling older adults. The associations with diurnal cortisol and depression, anxiety and social support were also examined in relation to age. Salivary cortisol was measured over the course of one day: immediately upon awakening, 30 min later, and then 3 h, 6 h, 9 h and 12 h post-awakening. Participants completed a questionnaire measuring symptoms of anxiety and depression and social support was assessed. Older adults exhibited a significantly reduced awakening response, overall cortisol levels, area under the curve (AUC) and diurnal slopes than younger adults, resulting in a flatter diurnal rhythm. Younger adults with higher depression scores had significantly higher overall cortisol and higher levels upon awakening and 30 min post-awakening. In the younger adults, anxiety and depression correlated positively with AUC and the cortisol awakening response (CAR). Older adults with lower social support had a reduced AUC where younger adults with lower social support displayed a larger AUC. These findings suggest that the diurnal rhythm and awakening response of salivary cortisol are significantly reduced in older adults and the associations between anxiety, depression and social support and diurnal cortisol vary with age.\ud \u

A Cost to Bear—Environmental Contamination and Eminent Domain

This Note advocates for Washington courts to adopt a system that universally allows evidence of environmental contamination on the private property taken in eminent domain proceedings. Part I of this Note discusses the history and progression of eminent domain and the broader constitutional roots of the Takings Clause. Part II explores Washington’s environmental remediation statute. Part III details the various approaches jurisdictions around the county have formulated to deal with this issue. Part IV argues Washington courts should adopt the inclusionary approach, which allows the introduction of environmental evidence in eminent domain proceedings

Is there a link between previous exposure to sport injury psychology education and UK sport injury rehabilitation professionals' attitudes and behaviour towards sport psychology?

Objectives: The use of sport psychology strategies during sport injury rehabilitation can lead to several positive outcomes such as improved adherence and self-efficacy. The purpose of this study was to compare the sport psychology related attitudes and behaviours of UK sport injury rehabilitation professionals (SIRPs) who had studied the psychological aspects of sport injury to those who had not. Participants and design: Ninety-four SIRPs (54 physiotherapists and 40 sports therapists with a mean of 9.22 years' experience of working in sport) completed an online survey and were grouped according to their level of previous exposure to sport injury psychology education at an undergraduate/postgraduate level. Analyses were undertaken to establish whether there were any differences in sport psychology related attitude (MANOVA), usage (MANOVA), and referral behaviours (chi square) between the groups. Results: The MANOVA and chi square tests conducted revealed that those who had studied the psychological aspects of sport injury reported using significantly more sport psychology in their practice and making more referrals to sport psychologists. Conclusions: It was concluded that sport injury psychology education appears to be effective in increasing the sport psychology related behaviours (use of sport psychology and referral) of SIRPs and should be integrated into professional training

The impact of a sport psychology education intervention on physiotherapists

The purpose of this study was to measure the impact of an online sport psychology education module on the attitudes and behaviours of qualified sports physiotherapists in the UK. Ninety-five sport physiotherapists studied either a sport psychology module or a control module, and their attitudes and behaviours towards sport psychology were measured prior to studying the module and at three points over a six-month period following its completion. It was found that those who had studied the sport psychology module demonstrated an improvement in their attitudes towards sport psychology immediately following its completion that was significantly higher than those who had studied the control module. Use of sport psychology also increased following the sport psychology module, with significant differences seen between the intervention and control group on the sport psychology subscale, indicating that those who had studied the sport psychology module were integrating more sport psychology techniques into their practice than those who had studied the control module. It was concluded that the online sport psychology module was effective in improving the attitudes and behaviours of UK physiotherapists and that more sport psychology education opportunities should be made available

Third-party effects of water trading and potential policy responses

A key feature of water policy reform in Australia has been the separation of water access entitlements from land titles and the establishment of markets for water. However, the separation of water entitlements from land failed to account for a number of characteristics that were implicit in the joint right. This has given rise to a number of third-party effects as water is traded in an incomplete market. This paper describes four third-party effects of water trade; reliability of supply, timeliness of delivery, storage and delivery charges, and water quality and examines policy responses to address these effects. The discussion draws on the concepts of exclusiveness and rivalry to determine the applicability of property rights and other solutions to the third-party effects of trade. It is likely that many of the third-party effects of trade discussed in this paper do not warrant policy intervention at the national or state level, but intervention at the local level may be warranted. The costs of addressing some third-party effects may outweigh the benefits. Where there are significant gains from trade, the existence of these third-party effects should not been seen as a reason to impede trade.property rights, water trading, third-party effects, Resource /Energy Economics and Policy,

Differential release of sewage sludge biochar-borne elements by common low-molecular-weight organic acids

Biochar materials originated from sewage sludge may contain elevated levels of potentially toxic elements. There was a lack of information on the mobility of biochar-borne elements, as driven by lowmolecular-weight organic acids (LMWOAs) contained in plant root exudates. A batch experiment was conducted to examine the effects of three common LMWOAs on the release of major elements and trace elements with a focus on various potentially toxic trace elements. The results showed that substantial amounts of Al, Mn, Fe, K, Na and Mg were extracted from two sewage sludge-derived biochar materials by the LMWOAs. A much higher release rate of potentially toxic trace elements was observed in the presence of LMWOAs, as compared to reported data using extractants not encountered in root exudates. The LMWOA-driven releasibility of various potentially toxic trace elements was in the following decreasing order: Zn > Ni > Pb > Cu > Cr > Co = Cd. Other trace elements that are subject to mobilization in the presence of LMWOAs included B, Ba, In, Li and Sr except Ba under oxalic acid extraction. Among the three LMWOAs, oxalic acid showed a generally stronger capacity to mobilize these metals. The findings obtained from this study provides new information that can be used for better evaluating the phyto-availability of trace elements bound to sewage sludge-originated biochar materials

Equilibrium and Disorder-induced behavior in Quantum Light-Matter Systems

We analyze equilibrium properties of coupled-doped cavities described by the Jaynes-Cummings- Hubbard Hamiltonian. In particular, we characterize the entanglement of the system in relation to the insulating-superfluid phase transition. We point out the existence of a crossover inside the superfluid phase of the system when the excitations change from polaritonic to purely photonic. Using an ensemble statistical approach for small systems and stochastic-mean-field theory for large systems we analyze static disorder of the characteristic parameters of the system and explore the ground state induced statistics. We report on a variety of glassy phases deriving from the hybrid statistics of the system. On-site strong disorder induces insulating behavior through two different mechanisms. For disorder in the light-matter detuning, low energy cavities dominate the statistics allowing the excitations to localize and bunch in such cavities. In the case of disorder in the light- matter coupling, sites with strong coupling between light and matter become very significant, which enhances the Mott-like insulating behavior. Inter-site (hopping) disorder induces fluidity and the dominant sites are strongly coupled to each other.Comment: about 10 pages, 12 figure
