Staff responses to age‐related health changes in people with an intellectual disability in group homes

The purpose of this study was to explore how supervisors in group homes caring for people with intellectual disability responded to the development of age‐related health changes in their residents. Ten group home supervisors working in the disability sector were interviewed once. Data were analysed using Dimensional Analysis. The study identified several factors related to whether a resident could stay ‘at home’ or would need to be moved to residential aged care (nursing home) including: nature and extent of group home resources, group home staff comfort with residents’ health changes, staff skill at navigating the intersection between the disability and ageing sectors, and the supervisor’s philosophy of care. The ability of older people with an intellectual disability to ‘age in place’ is affected by staff knowledge about and comfort with age‐related illnesses, staff skills at navigating formal services, staffing flexibility, and the philosophy of group home supervisors. Despite the growing international concern for the rights of people with disability, particularly in relation to decision making, questions about the older person’s choice of residence and participation in decision making about what was best for them, were almost nonexistent. Rather, decisions were made based on what was considered to be in ‘the best interest’.     

Rural‐Urban Differences in Environmental Concern in Canada

Abstract Distinctions between rural and urban populations are well documented in environmental sociology literature. Rural and urban places may exert different influences on participation in environmentally supportive behavior (ESB) as well as on other forms of environmental concern (EC). The influence of these distinct geographies may be due to present circumstances or because of childhood socialization in these places. Using data from a national survey in Canada (n=51 664), we use cognitive (basic values, environmental worldview, and environmental attitude) and behavioral indicators (public and private sphere) of EC to explore differences among rural and urban populations and we include analyses accounting for place of socialization. We extend the conventional private sphere category of ESB by including stewardship behaviors. Results showed few differences between rural and urban residents on indicators of EC. Rural residents, however, scored higher on altruistic values, placed a higher priority on the environment, and reported higher participation in recycling and stewardship behaviors. Analysis that included place of socialization showed differences on environmental worldview, basic values, and some ESB. In terms of ESB, we conclude that residence and place of socialization may be less of a factor than opportunity and highlight the importance of providing services and facilities. We recommend future research on residence and ESB include a variety of behaviors that reflect opportunities for both rural and urban residents.     

Inferring an Augmented Bayesian Network to Confront a Complex Quantitative Microbial Risk Assessment Model with Durability Studies: Application to Bacillus Cereus on a Courgette Purée Production Chain

The Monte Carlo (MC) simulation approach is traditionally used in food safety risk assessment to study quantitative microbial risk assessment (QMRA) models. When experimental data are available, performing Bayesian inference is a good alternative approach that allows backward calculation in a stochastic QMRA model to update the experts’ knowledge about the microbial dynamics of a given food‐borne pathogen. In this article, we propose a complex example where Bayesian inference is applied to a high‐dimensional second‐order QMRA model. The case study is a farm‐to‐fork QMRA model considering genetic diversity of Bacillus cereus in a cooked, pasteurized, and chilled courgette purée. Experimental data are Bacillus cereus concentrations measured in packages of courgette purées stored at different time‐temperature profiles after pasteurization. To perform a Bayesian inference, we first built an augmented Bayesian network by linking a second‐order QMRA model to the available contamination data. We then ran a Markov chain Monte Carlo (MCMC) algorithm to update all the unknown concentrations and unknown quantities of the augmented model. About 25% of the prior beliefs are strongly updated, leading to a reduction in uncertainty. Some updates interestingly question the QMRA model.     

Three Routes to Pension Reform: Politics and Institutions in Reforming Pensions in Denmark,Finland and Sweden

By analysing pension reforms in three Nordic countries – Denmark, Finland and Sweden – that apply different institutional solutions in their old‐age security programmes, this article argues that the political processes that shaped the country‐specific pension set‐ups in the 1950s and 1960s had important ramifications for subsequent reform possibilities. A high degree of inertia exists not only in the institutions themselves but also in the political reform options and the ways in which pensions were reformed. The analysis shows that the ‘new politics’ was not new in any of the three countries. Furthermore, given the differences in the three cases, the analysis questions the nature of pension reform. The Swedish reform in the late 1990s was a ‘big bang’ that eliminated the old and changed everything; the Finns built on piecemeal reforms of conversion that gradually changed the whole system; and, while the Danish story appears to be one of stability and status quo, the drift of Danish policy ultimately changed the basic characteristics of the system. Although all three countries have more or less thoroughly reformed their pensions, the reform processes have differed according to both historical legacies and institutional frameworks.     

Attitudes of Arab and Jewish mothers towards punitive and non‐punitive discipline methods

This study used data from 234 Jewish and Arab mothers in Israel to determine the association between cultural and socioeconomic factors on their views of punitive and non‐punitive discipline behaviours. Mothers highly approved the use of nonpunitive disciplines. For example, all mothers supported to explain to the child what the rules are to try to prevent misbehaviour; however, their support of punitive disciplines was not negligible. For instant, 15.32% approved spank, slap, smack or swat children; one out of 10 mothers endorsed using an object such as a paddle, hairbrush, belt, etc. on children. Mothers with lower levels of education (completing high school or lower) and Arab mothers approved the use of corporal punishment and psychological aggression more than others. More support and training are required for these families.     

A Quantitative Assessment of the Risk for Highly Pathogenic Avian Influenza Introduction into Spain via Legal Trade of Live Poultry

Highly pathogenic avian influenza (HPAI) is considered one of the most important diseases of poultry. During the last 9 years, HPAI epidemics have been reported in Asia, the Americas, Africa, and in 18 countries of the European Union (EU). For that reason, it is possible that the risk for HPAI virus (HPAIV) introduction into Spain may have recently increased. Because of the EU free‐trade policy and because legal trade of live poultry was considered an important route for HPAI spread in certain regions of the world, there are fears that Spain may become HPAIV‐infected as a consequence of the legal introduction of live poultry. However, no quantitative assessment of the risk for HPAIV introduction into Spain or into any other EU member state via the trade of poultry has been published in the peer‐reviewed literature. This article presents the results of the first quantitative assessment of the risk for HPAIV introduction into a free country via legal trade of live poultry, along with estimates of the geographical variation of the risk and of the relative contribution of exporting countries and susceptible poultry species to the risk. The annual mean risk for HPAI introduction into Spain was estimated to be as low as 1.36 × 10⁻³, suggesting that under prevailing conditions, introduction of HPAIV into Spain through the trade of live poultry is unlikely to occur. Moreover, these results support the hypothesis that legal trade of live poultry does not impose a significant risk for the spread of HPAI into EU member states.     

The Extended Skew-Exponential Power Distribution and Its Derivation

We consider an extended family of asymmetric univariate distributions generated using a symmetric density, f, and the cumulative distribution function, G, of a symmetric distribution, which depends on two real-valued parameters λ and β and is such that when β = 0 it includes the entire class of distributions with densities of the form g(z | λ) = 2 G(λ z) f(z). A key element in the construction of random variables distributed according to the family is that they can be represented stochastically as the product of two random variables. From this representation we can readily derive theoretical properties, easy-to-implement simulation schemes, as well as extensions to the multivariate case and an explicit procedure for obtaining the moments. We give special attention to the extended skew-exponential power distribution. We derive its information matrix in order to obtain the asymptotic covariance matrix of the maximum likelihood estimators. Finally, an application to a real data set is reported, which shows that the extended skew-exponential power model can provide a better fit than the skew-exponential power distribution.     

Conference reports

The lack of women engaging themselves in science has been thoroughly discussed in feminist and nonfeminist science studies. It has remained a mystery why so few female students take professional careers as scientists. Though more and more female students enroll in physics studies, for example, they seem to disappear before they reach academic positions. Instead of discussing this as a query of gender inequality in this article, I discuss the more general issues of inclusion and exclusion in communities of practices. I argue that selection mechanisms in a group of students can be connected to their premises for engaging themselves in an activity. As students have different embodied experiences, they also have different premises for engaging themselves. What seems like the same practice can, in fact, be analyzed as practices belonging to different activities. This approach might bring us a small step further in the discussions of the relations between gender and science.
