Profust reliability of linear and circular type F and G systems having two failure criteria under Markov dependency

In this study, the profust reliabilities of (n, f, k): F(G) and < n, f, k > : F(G) systems for Markov dependent components are investigated. Having two failure criteria are the common features of these four systems. The usage of both fuzzy approach and two failure criteria in the same system provides us more realistic approach to evaluate the reliability of more complex systems. The component configurations are examined for both linear and circular sequences and the working principle of systems are studied for both F and G systems. Under all these assumptions, the profust reliabilities of (n, f, k): F(G) and < n, f, k > : F(G) systems are obtained using the distribution of run statistics. Also a new membership function different from the linear membership function which is generally used in the literature is proposed. Some numerical results which allow the comparison of the systems from various perspectives and various figures for both linear and circular type systems are presented. Some special cases (between Markov – iid assumption, conventional – profust reliability) are also considered.     

The Merry-Go-Round of Meetings: Embracing Meetings in a Swedish Youth Care Project

Modern society has been called “a society of organizations,” and meetings are considered indispensable. However, a recurring cultural theme in contemporary working life is complaints about excessive and time-consuming meetings. The present article analyzes a contrasting case concerning a Swedish youth care project that employed a set of “coordinators” to maintain close contact with young people and their parents. Over time, these coordinators adopted an exceedingly administrative approach in which meetings with other professionals became more and more central. This article explores how an expanding meeting culture with strong social commitments can be generated from within interorganizational contexts, such as “projects,” and successfully competes with other concerns. Thus, the administrative orientation represents an example of the type of social interaction process that Simmel discerned as Eigendynamik or autonomous processes of social interaction.     

Public response to welfare policy retrenchment: The importance of trust in implementing agencies. The case of early retirement in Sweden 1999–2010

There is a long-standing argument that citizensapos; trust in the state needs to be recurrently reproduced for policies to endure and that this also includes trust in its separate policy agencies. Such trust is likely to be more important for costlier policies, as, for example, social insurance schemes. The article explores whether short-term changes in welfare programme generosity affect peopleapos;s trust in the agency implementing the programme. Using the example of early retirement in the encompassing welfare state of Sweden, we study a decade of significant reform (1999–2010), during which the inflow to early retirement diminished greatly, as did citizensapos; trust in the implementing Swedish Social Insurance Agency (SSIA). We conclude that citizensapos; trust is higher when implementation is more generous. Indeed, a third of the drop in citizensapos; trust in the SSIA over the period can be explained by declining levels of generosity in early retirement, with people politically to the left responding with lower trust. Theoretically, we suggest, first, that trust in implementing institutions can function as feedback to policy and, second, that there is a basic relationship between more generous policy outcome and higher trust in encompassing welfare states such as Sweden.     

Value orientations and social attitudes in the holistic milieu

Based on a representative population survey for Germany this article investigates whether engagement in holistic activities is associated with privatized lifestyles and lack of social responsibility or with countercultural orientations and base‐democratic political commitment. To analyse this question, respondents who are engaged in holistic activities are divided into three groups that are compared with each other as well as with Christians and non‐religious people. The findings show that the three holistic groups are characterized by clearly different attitudinal patterns: Respondents engaged in body‐mind‐spirit activities have an affinity to self‐directed ways of life, post‐materialism and environmentalism. Holistic Christians try to combine the Christian ideal of altruism and post‐materialist orientations. Those who are attracted only to magical‐occult practices are primarily concerned with individualistic self‐improvement and correspond more to the image of the hedonist consumer at the esoteric marketplace.     

Conflict and Curiosity: The Legacy of Naoki Ueno

ABSTRACT

This commentary explores conflicts and dissonances between my own views, based on cultural-historical activity theory, and three key ideas presented in the articles of this special issue, namely (a) technology as partner, (b) agency as hybridization, and (c) historicity without contradictions. I hope that the dissonances I put forward will evoke curiosity and further exploration. In his work, Naoki Ueno drew on multiple theoretical traditions. This diversity, combined with his curiosity and love of life, allowed him to be involved in the building and analysis of future-making “wildfire” alternatives to capitalism. This is a legacy that must and will gain momentum.     

Training research-minded social workers: experience from Estonia*

ABSTRACT

Social work education in its modern sense started to develop after Estonia regained independence from the collapsing Soviet Union. The aim of this article is to introduce good practices of teaching research-mindedness, this being one of the main principles in teaching social workers-to-be in the University of Tartu in Estonia. We have been inspired by the academic tradition of university teaching in general, the new international definition of social work and, not least, the realisation of social workers in practice of not being able to apply academic knowledge to everyday social work practices. This article revisits the term research-mindedness and examines how it has been integrated into the university level teaching process. Our purpose is to discuss the methods students of bachelor’s and master’s programmes can learn to ‘translate’ social issues into research questions, critically appraise the findings and ‘translate’ them back as new research evidence for social work practice.     

How an aging society affects the economic costs of inactivity in Germany: empirical evidence and projections

Background

Aging societies represent a major challenge for health care systems all over the world. As older people tend to be more physically inactive, economic costs of inactivity are likely to increase notably. The present study aims to investigate this relationship between an aging society and economic costs of inactivity using the example of Germany.

Methods

Using data from the German Socio-Economic Panel, this study applied the comparative risk assessment method developed by the WHO to estimate the direct costs of inactivity for the period 2001–2013 differentiated by gender-specific age-groups (15–29; 30–44; 45–64; 65+). Based on population statistics predicting the aging of the German population for the years 2014–2060, this research projects the development of future costs of inactivity and potential effects of interventions promoting physical activity among the German population.

Results

The results reveal an increase in the level of physical activity during the observed period (2001–2013) which compensated the negative effect of aging and resulted in a decline of inactivity costs. The projections for the years 2014–2060 indicate a constant increase in direct per capita costs until 2060 because of an aging society. Scenarios indicating how a short-term reduction of physical inactivity impacts costs of inactivity reveal the crucial role of the oldest age-group in this context.

Conclusion

The findings indicate that the aging of the German population demands further actions and initiatives to promote physical activity, especially for the oldest age-group.

     

Permutation approach for ordinal preference data

Best et al. (Best, D. J., Rayner, J. C. W., O'Sullivan, M. G. (2000 Best, D. J., Rayner, J. C. W., O'Sullivan, M. G. (2000). Product maps for consumer categorical data. Food Quality and Preference 11:91–97.[Crossref], [Web of Science ®] , [Google Scholar]). Product maps for consumer categorical data. Food Quality and Preference, 11:91–97) suggested tests based on partitioning the X² statistic into relevant components of location, dispersion, and skewness effects for testing equality of each effect for ordinal preference data. It is known that the chi-square approximation requires large counts for categories. For this purpose, in this study, we investigate a permutation approach for these statistics and compare the performance of these tests with simulation study. In addition, the permutation approach can be used to produce a product map that classifies the products. We illustrate the approach with a real data example.
