    Purpose– Modern working life is characterized by increased expectations for employees to be available to deal with work issues outside regular work hours and by using new communication technology. This implies more individual freedom in organizing work in time and space, but also places increased demands on employees to manage the boundaries between work and personal life. This, in turn, can be expected to be crucial to their ability to mentally detach from work during free time. The purpose of this paper is to investigate whether individual perceptions of boundary control moderate the impact of after-hours availability expectations and work-related smartphone use during off-work hours on psychological detachment. Design/methodology/approach– The study population comprised 2,876 gainfully employed professionals from four large organizations in both the public and private sector, representing various businesses and occupations. Univariate correlations and multiple, linear hierarchical multiple regression analyses were performed. Findings– High after-hours availability expectations, high frequency of work-related smartphone use, and low boundary control were associated with poor psychological detachment. Furthermore, boundary control moderated the relationships between both after-hours availability expectations and work-related smartphone use, respectively, and psychological detachment. As such, boundary control mitigated the negative effects of both after-hours availability expectations and work-related smartphone use during leisure on psychological detachment. Practical implications– Modern work organizations would benefit from introducing availability policies and helping employees reduce their work-related smartphone use outside regular work hours, thus helping them achieve successful boundary control and subsequent psychological detachment. Originality/value– In a working life characterized by blurred boundaries, employees’ ability to achieve boundary control can be regarded as crucial.

    The aim was to examine hospitalization due to stroke and acute myocardial infarction, respectively, and to analyze differences between the self-employed and paid employees in the same industries. Data and methods: Data from Statistics Sweden's population register (2003) was linked to National Board of Health and Welfare’s hospital admission register and cause of death register (2004-2008). More than 4.7 million people (7% self-employed) were included in the analyses. Individuals were classified on the basis of their occupational status as self-employed persons or employees. The self-employed were further classified as sole proprietors or limited liability company owners according to the legal form of self-employment. Based on the Swedish Standard Industrial Classification (SNI 2002) eight industries were distinguished. Diagnoses of hospitalization were classified as stroke (intracerebral hemorrhage I61, cerebral infarction I63, and unspecified acute cerebrovascular disease I64) and acute myocardial infarction (I21) based on the international classification of diseases (ICD-10). Stroke and Myocardial Infarction (MI) hospitalization incidence rate ratios (IRR) and 95% confidence intervals (CI) were estimated using negative binomial regression models adjusted for pre-specified potential confounding covariates. Effect modification by occupational status, industrial sector, and gender was investigated with two and three-way interaction terms.

    Stressreaktioners styrka beror inte bara på hur mycket och hur ofta människor arbetar utan hör även samman med ett arbetsuppdrags sociala innebörd. Forskningen om illegitima arbetsuppgifter och stress inkluderar denna sociala aspekt, vilken antas vara relaterad till individens självuppfattning och identitet. I artikeln introduceras en modell om illegitima uppgifter som identitetsrelevanta stressorer. Dessutom redovisas en empirisk studie av tre yrkesgrupper kring sambandet mellan identitetsrelevanta stressorer och ohälsoreaktioner.

    Objectives: Analyse mortality differences between self-employed and paid employees with a focus on industrial sector, educational level and gender using Swedish register data.

    Methods: A cohort of the total working population (4 776 135 individuals; 7.2% self-employed; 18–100 years of age at baseline 2003) in Sweden with a 5-year follow-up (2004–2008) for all-cause and cause-specific mortality (57 743 deaths). Self-employed individuals were categorised as sole proprietors or limited liability company (LLC) owners according to their enterprise’s legal form. Cox proportional hazards models were applied to compare mortality rates between sole proprietors, LLC owners and paid employees, adjusted for sociodemographic confounders.

    Results: Mortality from cardiovascular diseases was 16% lower and from suicide 26% lower among LLC owners than among paid employees, adjusted for confounders. Within the industrial category, all-cause mortality was 13–15% lower among sole proprietors and LLC owners compared with employees in manufacturing and mining (MM) as well as personal and cultural services (PCS), and 11–20% higher in sole proprietors in trade, transport and communication and the welfare industry (W). A significant three-way interaction indicated 17–23% lower all-cause mortality among male LLC owners in MM and female sole proprietors in PCS, and 50% higher mortality in female sole proprietors in W than in employees in the same industries.

    Conclusions: Mortality differences between selfemployed individuals and paid employees vary by the legal form of self-employment, across industries, and by gender. Differences in work environment exposures and working conditions, varying market competition across industries and gender segregation in the labour market are potential mechanisms underlying these findings.

    Objectives: This study investigated mortality differentials between self-employed persons in Sweden, considering industrial sector, enterprise characteristics and socio-demographic factors.

    Methods: Data on 321,274 self-employed persons were obtained from population registers in Sweden. Cox proportional hazards models were used to compare all-cause and cause-specific mortality rate ratios by industrial sector and enterprise legal form, adjusted for confounders.

    Results: All-cause mortality was 10–32% higher in self-employed persons in Manufacturing and Mining, Trade and Communication, and Not Specified and Other sectors than in Agriculture, Forestry, and Fishing. Mortality from cardiovascular disease was 23% higher in Trade and Communication, and from neoplasms 17–51% higher in Manufacturing and Mining, Not Specified, and Other. Mortality from suicide was 45–60% lower in Personal and Cultural Services, and in Not Specified. Mortality was 8–16% higher in sole proprietorship than limited partnership.

    Conclusions: Further research of working conditions is warranted, considering industry and enterprise legal form.
