Visual ergonomics interventions in mail sorting facilities

This study was performed between 2004 and 2011 at mail sorting facilities in Sweden. During this time, different interventions were performed. The first was a lighting intervention that had a positive impact on the postal workers, especially those with eyestrain. A new lighting system also improved the illuminance and gave better light distribution. The second intervention involved new personal spectacles for the postal workers who needed them and this had a positive effect on eyestrain. The third intervention involved a specific type of sorting spectacles for the postal workers who already used progressive lenses privately. The reading distances that the postal workers had while sorting the mail was inverted to the distances in their regular progressive lenses. The new sorting spectacles had a positive effect on head postures and on muscular activity.     

Will the EU Disintegrate? What Does the Likely Possibility of Disintegration Tell About the Future of the World?

Is it true that either the EU will be democratised or it will disintegrate? I concur that the current policies, principles, and institutions of the EU both generate counterproductive politico-economic effects and suffer from problems of legitimation. These effects and problems, which are not confined to Europe, give rise to tendencies towards disintegration. My second point concerns the timing of the required learning and reforms. Modest policy proposals and tentative steps within the existing EU Treaty framework may be too little too late. The question is whether there is enough time for deeper transformations in Europe—and also globally.     

Non‐parametric Bayesian Intensity Model: Exploring Time‐to‐Event Data on Two Time Scales

Time‐to‐event data have been extensively studied in many areas. Although multiple time scales are often observed, commonly used methods are based on a single time scale. Analysing time‐to‐event data on two time scales can offer a more extensive insight into the phenomenon. We introduce a non‐parametric Bayesian intensity model to analyse two‐dimensional point process on Lexis diagrams. After a simple discretization of the two‐dimensional process, we model the intensity by a one‐dimensional piecewise constant hazard functions parametrized by the change points and corresponding hazard levels. Our prior distribution incorporates a built‐in smoothing feature in two dimensions. We implement posterior simulation using the reversible jump Metropolis–Hastings algorithm and demonstrate the applicability of the method using both simulated and empirical survival data. Our approach outperforms commonly applied models by borrowing strength in two dimensions.     

Statistical tests for the comparison of two samples: The general alternative

It is common to test the null hypothesis that two samples were drawn from identical distributions; and the Smirnov (sometimes called Kolmogorov–Smirnov) test is conventionally applied. We present simulation results to compare the performance of this test with three recently introduced alternatives. We consider both continuous and discrete data. We show that the alternative methods preserve type I error at the nominal level as well as the Smirnov test but offer superior power. We argue for the routine replacement of the Smirnov test with the modified Baumgartner test according to Murakami (2006) Murakami, H. (2006).

Family support services buffer the effect of child welfare notifications on child removals

Previous studies have found mixed results about the effects of family support services within the child protection system. The purpose of the study is to examine whether family support services are associated with the need for child removals at the community level. The material of the study consists of Finnish municipalities (N = 292) and their child protection indicators. Linear regression analysis was conducted to analyse the associations between the dependent variable (child removals) and the main predictors (child welfare notifications and family support services). It was found that family support services are associated with child removals. The more children there are in family support services, the more there are also child removals in a municipality. The key finding of the analysis is that a higher rather than lower proportion of clients in family support services buffers the increased effect of demand (child welfare notifications) on child removals better. In this sense, the demand for child removals is not only associated with the characteristics of children and families but may be partly explained by the role of family support services in a municipality. The present study underlines the significance of a system-level approach to child protection.

Staying inside: social withdrawal of the young,Finnish ‘Hikikomori’

This article explores socially withdrawn young Finnish people on an Internet forum who identify with the Japanese hikikomori phenomenon. We aim to overcome the dualism between sociology and psychology found in earlier research by referring to Pierre Bourdieu, who provides insights into how individual choices are constructed in accordance with wider social settings. We focus on the individual level and everyday choices, but we suggest that psychological factors (anxiety, depression) can be seen as properties of social relations rather than as individual states of mind, as young adults have unequal access to valued resources. We scrutinise young people’s specific reasoning related to the social and psychological factors and contingent life events that influence their choice to withdraw. An experience of inadequacy, a feeling of failure and a lack of self-efficacy are common experiences in the data. This indicates that young adults who identify with the hikikomori phenomenon find external society demanding and consider themselves lacking resources such as education, social networks or the personality type that they see as valued in society and as essential to ‘survival’. They also feel that they cannot control their life events, which may mean that they receive little help in their everyday lives.     

Social Impact Investing in Germany: Current Impediments from Investors’ and Social Entrepreneurs’ Perspectives

The paper provides empirical evidence on impediments of the emerging social impact investment field in Germany. The study is based on 19 in-depth interviews with social impact investing funds, investment advisors, and social entrepreneurs as investees. It takes an explorative approach because of the nascent stage of research on the subject. By systematically relating the perspectives of the actors involved, the study gives a broad empirical picture on the major challenges for social impact investing in Germany. Results reveal nine critical problem areas we have arranged along three dimensions: financial returns, social returns, and relationships and infrastructure. They comprise investors’ and social entrepreneurs’ practices, institutional settings which are still heavily influenced by peculiarities of the German welfare systems, as well as undeveloped framework conditions in the social investment market. By interpreting the results through a lens of conflicting institutional logics, we further contribute to this research stream by showcasing social impact investing as a core area of friction between the logics of the market and civil society.
