Does yoga engender fitness in older adults? A critical review

Interest in yoga is growing, especially among older adults. This review critically summarizes the current literature to investigate whether physical fitness and function benefits are engendered through the practice of yoga in older adults. A comprehensive search yielded 507 studies; 10 studies with 544 participants (69.6 ± 6.3 yr, 71% female) were included. Large variability in yoga styles and measurement outcomes make it challenging to interpret results across studies. Studies reported moderate improvements for gait (ES = 0.54, 0.80), balance (ES = 0.25-1.61), upper/lower body flexibility (ES = 0.25, 0.70), lower body strength (ES = 0.51), and weight loss (ES = 0.73, 0.99).Yoga may engender improvements in some components of fitness in older adults. However, more evidence is needed to determine its effectiveness as an alternative exercise to promote fitness in older adults. Further investigation into yoga as an exercise activity for older adults is warranted.     

Techniques of neutralising wildlife crime in rural England and Wales

Within rural studies there have been few attempts to critically analyse crimes against nature. This paper addresses this gap by providing an analysis of farmers’ reasons for illegally culling badgers in the United Kingdom. Drawing on Sykes and Matza’s (1957) concepts of neutralisation and drift, the paper shows how farmers rationalise this activity. Using in-depth interviews with 61 farmers in the England and Wales, the paper shows how they justify badger culling through discursive strategies that claim the activity is necessary, deny the necessity of the law, condemning the condemners, and appealing to community loyalties The paper also shows that neutralisation helps identify contextual factors that allow farmers to drift ambiguously between deviant values and social norms. In the case of badger culling, drift is attributable to an attack on a particular rural identity and way of living that has left farmers perceiving their selves as an effect. As much as they are attempts to rationalise criminal behaviour, neutralisation techniques can also be seen as spatial discourses demarcating the boundaries of cultural and spatial identities. In conclusion, the paper discusses the implications for resolving the problems of wildlife crime.     

Bayesian inference for non-Gaussian Ornstein–Uhlenbeck stochastic volatility processes

Summary.  We develop Markov chain Monte Carlo methodology for Bayesian inference for non-Gaussian Ornstein–Uhlenbeck stochastic volatility processes. The approach introduced involves expressing the unobserved stochastic volatility process in terms of a suitable marked Poisson process. We introduce two specific classes of Metropolis–Hastings algorithms which correspond to different ways of jointly parameterizing the marked point process and the model parameters. The performance of the methods is investigated for different types of simulated data. The approach is extended to consider the case where the volatility process is expressed as a superposition of Ornstein–Uhlenbeck processes. We apply our methodology to the US dollar–Deutschmark exchange rate.     

Local Voices in an Internal Market: The Case of Community Health Services*

This paper presents findings from a study of contract specification and implementation in community health services (CHS). In this paper, we focus on one aspect of that study: the role of local people in informing the assessment of health needs and in determining the provision of community health services in the context of the NHS “internal market”. The paper is based on fieldwork undertaken in three districts within one region. Analysis of data obtained from these localities suggests that while there appears to be a genuine commitment to the principle of local involvement, ideas about how that involvement can be built into the activities of either purchasers or providers are less transparent.     

Responding to student mental health concerns in social work education: reflective questions for social work educators

In this paper, we explore ways in which social work educators might respond to students who report that mental health issues underlie their difficulty in meeting core competencies, or otherwise use the language of mental health to describe their struggles to succeed in social work programs. We discuss various trends in policy responses in Canada, the US, the UK, and Ireland. While there are general policy trends, it is clear that responding to these kinds of issues requires the development of highly flexible and situated policy processes that can respond to student realities, concern for students’ rights and privacy, and an awareness of potential discrimination against students. These processes also need to meet the specificities of practicums, particular institutional policies, the mandates of relevant professional bodies, and the precise local legislative framework that shapes these situations. Given these varying contexts, in this conceptual paper, we used a framework on disability that is informed by critical theory to engage existing school policies and propose a set of reflective questions that can guide schools of social work to create an overall responsive environment. These reflective questions are designed to help social work educators balance the rights and needs of students with the professional and institutional demands that students meet core competencies in their education.     

On the Asymmetric Volatility of Employment Outflows

Recent research into job flow dynamics highlights the asymmetry in aggregate employment adjustment. This has implications for patterns of worker flow adjustment. This paper draws upon modelling strategies developed in the applied finance literature to characterize the asymmetry of aggregate employment outflow volatility. It is found that higher employment outflow volatility is associated with negative shocks, when the outflow is lower than expected. This, it is suggested, could be associated with the dynamic processes linking the hiring and turnover of workers.
