Perception and control of occupational injury risks in fishery--a pilot study

The frequency of occupational accidents in fishery is high in most fishery nations. Implementation of safety measures has, however, been limited. The purpose of the present cross-sectional study was to explore Swedish fishermen's attitudes towards occupational risks and accident control. Information was acquired through a questionnaire distributed to a convenience sample of 92 fishermen. Indices were built, containing variables relevant to perceived risk levels in connection with work, perceived manageability of risks, activity in safety work, technical knowledge and individual attitudes towards risks. The results did not support earlier findings of low risk awareness and risk acceptance among fishermen. Perceived manageability of risks but not perceived risk level, accident experience or risk acceptance, were significantly associated with activity in safety work. The results suggest that safety work might benefit from efforts to develop fishermen's understanding of how the development of hazardous situations can be prevented or managed. The results do not support strategies for accident control in fishery based solely on increasing risk awareness.     

Notes on authors

Social network analysis (SNA), a method which can be used to explore networks in various contexts, has received increasing attention. Drawing on the development of European smoke-free policy, this paper explores how a mixed-method approach to SNA can be utilised to investigate a complex policy network. Textual data from public documents, consultation submissions and websites were extracted, converted and analysed using plagiarism detection software and quantitative network analysis and qualitative data from public documents and 35 interviews were thematically analysed. While the quantitative analysis enabled understanding of the network’s structure and components, the qualitative analysis provided in-depth information about specific actors’ positions, relationships and interactions. The paper establishes that SNA is suited to empirically testing and analysing networks in EU policy-making. It contributes to methodological debates about the antagonism between qualitative and quantitative approaches and demonstrates that qualitative and quantitative network analysis can offer a powerful tool for policy analysis.     

Sexual orientation and full-time monthly earnings, by public and private sector: evidence from Swedish register data

In this paper we explore annual earnings as well as full-time monthly earnings differentials resulting from sexual orientation. We observe that gay males are at an earnings disadvantage compared to male heterosexuals regardless of which earnings measure we use. This earnings disadvantage is found to be larger when we compare gay and heterosexual males who are working full-time. In addition, the disadvantage is larger in the private than in the public sector. Lesbians, however, earn more than heterosexual females. This earnings advantage is considerably smaller when we study full-time monthly rather than annual earnings but an earnings advantage for lesbians at the top of the earnings distribution is documented regardless of which earnings measure we use. In addition, lesbians are doing better than female heterosexuals in the public sector. To sum up, the results indicate that gay males face obstacles on the labor market that hinder them from reaching top-level positions and high earnings. The earnings advantage observed for lesbians is likely to stem from the fact that lesbians devote more time to market work than heterosexual females do.     

Estimation of the Force of Infection from Current Status Data Using Generalized Linear Mixed Models

Based on sero-prevalence data of rubella, mumps in the UK and varicella in Belgium, we show how the force of infection, the age-specific rate at which susceptible individuals contract infection, can be estimated using generalized linear mixed models (McCulloch & Searle, 2001). Modelling the dependency of the force of infection on age by penalized splines, which involve fixed and random effects, allows us to use generalized linear mixed models techniques to estimate both the cumulative probability of being infected before a given age and the force of infection. Moreover, these models permit an automatic selection of the smoothing parameter. The smoothness of the estimated force of infection can be influenced by the number of knots and the degree of the penalized spline used. To determine these, a different number of knots and different degrees are used and the results are compared to establish this sensitivity. Simulations with a different number of knots and polynomial spline bases of different degrees suggest - for estimating the force of infection from serological data - the use of a quadratic penalized spline based on about 10 knots.     

Ethnic Enclaves,Networks and Self‐Employment among Middle Eastern Immigrants in Sweden

The proportion of immigrants from countries in the Middle East living in Sweden has increased since the 1970s, and it is a well‐known fact that immigrants from the Middle East suffer from low earnings and high rates of unemployment on the Swedish labour market. There are often great hopes that self‐employment will enable immigrants to improve their labour market situation. Further, in Sweden as in many other countries, the question of whether the existence of ethnic enclaves are good or bad for immigrants’ earnings and employment opportunities has also been widely debated. This paper presents a study of the extent to which Middle Eastern ethnic enclaves and networks in Sweden enhance or hinder immigrants’ self‐employment. The results show that the presence of ethnic enclaves increases the propensity for self‐employment. Thus, immigrants in ethnic enclaves provide their co‐ethnics with goods and services that Swedish natives are not able to provide. The results also show that ethnic networks seem to be an obstacle to immigrant self‐employment. One explanation is that an increase in network size implies increased competition for customers among self‐employed immigrants. The question of whether ethnic enclaves are good or bad for the integration of immigrants into the labour market has been widely debated. The results of this paper provide us with information about the integration puzzle. Ethnic enclaves seem to enhance self‐employment propensities among Middle Eastern immigrants in Sweden.     

Transmission of self-employment across immigrant generations: the importance of ethnic background and gender

This paper studies the intergenerational transmissions of self-employment abilities among immigrants in Sweden. The results show that second-generation immigrants are over-represented in self-employment compared to natives. Male immigrants from countries neighbouring to Sweden and natives alike seem to use both mothers and fathers as role models in their self-employment decision, but the father is the stronger role model among male immigrants from more geographically distant regions. Female immigrants use both their father and their mother as role models in their self-employment decision. Furthermore, male immigrants and male natives tend to become self-employed in the same business sector as their fathers; female immigrants and female natives with self-employed parents are over-represented in self-employment but not necessarily in the same business sector as their parents.
