Perceived physical work capacity, stress, sleep disturbance and occupational accidents among firefighters working during a strike

Fire-fighting and rescue work are arranged in such a way that various kinds of accidents and catastrophes can be handled. In an understaffed situation, such as a strike, this goal may not be met. The objective of this study was to investigate factors associated with perceived physical work capacity, stress, sleep disturbance, and occupational accidents among firefighters who remained at work during an extended strike. A cross-sectional questionnaire study was carried out among 543 firefighters (83% of the target group) in 71 fire brigades in Finland. After the strike had lasted for 9 to 11 weeks, most of the firefighters perceived their physical work capacity to be rather good or very good. Stress increased along with a decreasing number of personnel in a crew (OR= 2.3, CI= 1.0-5.3, for less than 75% of a normal crew vs. normal crew) and with decreasing number of personnel in a shift (OR= 2.4, CI= 1.1-5.4, for less than 25% of normal shift vs. normal shift). Sleep disturbance was reported to occur as soon as the total working time exceeded 50 h/week. Working more than 70 h/week increased the risk of occupational accidents almost 4-fold compared with working no more than 50 h/week. These results suggest that exceptional situations, such as a strike, are a challenge to human capacity. With time, increased stress and sleep disturbance may lead to serious consequences.     

From Genius of the Home to Party Princess

The data for this article consist of alcohol-related advertisements published in seven Finnish women's magazines from 1967 to 2006. We are interested in finding out what kind of alcohol-related subject positions these magazines have created for women audiences from the 1960s onwards, to see how those positions have changed and what these changes tell us about the changes that have happened in the cultural position of drinking in Finland. Our analysis applies semiotic and discourse analytical methods. It shows that in the advertisements from the 1960s, women were placed in the subject position of full-time mother responsible for taking care of the heterosexual relationship. Women's drinking was associated with the private space of the home, with eating meals and socialising with family and friends. Women's subject positions in the 1970s and 1980s were still largely the same, but they also took on slightly new features. The 1990s and 2000s saw the emergence of the active woman who appears in public places, and drinking was associated with women's own time, enjoyment and pleasure. During the period under review we see the emergence of a drinking, self-assertive woman who is a responsible and distinctive consumer, a consumer who toys with stereotypes, and a partying consumer.     

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.     

Sum-of-squares rank upper bounds for matching problems

The matching problem is one of the most studied combinatorial optimization problems in the context of extended formulations and convex relaxations. In this paper we provide upper bounds for the rank of the sum-of-squares/Lasserre hierarchy for a family of matching problems. In particular, we show that when the problem formulation is strengthened by incorporating the objective function in the constraints, the hierarchy requires at most \(\left\lceil \frac{k}{2} \right\rceil \) levels to refute the existence of a perfect matching in an odd clique of size \(2k+1\).     

Attitudes to prioritization in selected health care activities

The aim of this study was to measure attitudes to health care prioritization in various Finnish population groups. Three study groups were established: 1) the general public (n=4260); 2) politicians (n=1427); and 3) medical and social work professionals (n=1055).
The following background data were obtained: sex, year of birth, marital status, number of children, education, profession, personal income, self-perceived health, and how subjects viewed their own future and whether they were satisfied with their lives. Information on activities involving prioritization of health service was elicited by presenting a list of 16 health care activities. Respondents evaluated these activities as 1) more important than average, 2) of average importance, or 3) less important than average (indicated as numbers 1-3).
The response rate was 59.3%, and 57.2% (n=3858) of the original sample was accepted for analysis. The politicians and profes-sionals showed almost identical attitudes. All groups prioritized treatment of life-threatening diseases among children. The general public prioritized high-tech surgery more highly than professionals or politicians. Alternative medicine and cosmetic surgery were the two least important activities. All groups agreed about prioritization of serious diseases among children, care of dying patients, prevention, surgery which helps people to perform their everyday tasks, and home care for the disabled elderly. Professionals and politicians prioritized mental health more highly than the population. The general public prioritized intensive care for premature babies with a low birth weight (less than 800 g). Professionals prioritized family planning more highly than politicians and the population. The results resemble those obtained in Britain, indicating that attitudes towards priorities in health are similar between Britain and Finland, and that the respondents' professions determine attitudes more strongly than does cultural background.     

Gatekeeping in child welfare: a comparative study of intake decisionmaking by social workers in Canada and Sweden

This article details findings from social workers in Sweden and Canada, illuminating similarities and differences in gatekeeping in child welfare and child protection. Analysis revealed different patterns of inclusion and exclusion. Swedish child welfare includes a greater readiness to intervene with more resources and measures. Gatekeeping is assessment driven and focused on family preservation. In Canada, only the most needy children are eligible for a limited range of services. Gatekeeping is structure driven and narrowly focused on protection. Analyses of evidence-based research to improve outcomes for children and families must include comparisons of how different structural orientations influence management of referrals at intake. The authors discuss the implications of these findings.     

Risk Analysis of Finnish Peacekeeping in Kosovo

The research team interviewed over 90 Finnish battalion members in Kosovo, visited 22 units or posts, registered its observations, and made any necessary measurements. Key persons were asked to list the most important risks for occupational safety and health in their area of responsibility. Altogether, 106 accidents and 40 cases of disease resulted in compensation claims in 2000. The risks to the peacekeeping force were about twice those of the permanent staff of military trainees in Finland. Altogether, 21 accidents or cases of disease resulted in sick leave for at least 3 months after service. One permanent injury resulted from an explosion. Biological, chemical, and physical factors caused 8 to 9 occupational illnesses each. Traffic accidents, operational factors, and munitions and mines were evaluated to be the three most important risk factors, followed by occupational hygiene, living conditions (mold, fungi, dust), and general hygiene. Possible fatal risks, such as traffic accidents and munitions and explosives, received a high ranking in both the subjective and the objective evaluations. One permanent injury resulted from an explosion, and two traffic accidents involved a fatality, although not of a peacekeeper. The reduction of sports and military training accidents, risk-control programs, and, for some tasks, better personal protection is considered a development challenge for the near future.     

The Emergence and Stability of the Attentional Bias to Fearful Faces in Infancy

Several studies have shown that at 7 months of age, infants display an attentional bias toward fearful facial expressions. In this study, we analyzed visual attention and heart rate data from a cross‐sectional study with 5‐, 7‐, 9‐, and 11‐month‐old infants (Experiment 1) and visual attention from a longitudinal study with 5‐ and 7‐month‐old infants (Experiment 2) to examine the emergence and stability of the attentional bias to fearful facial expressions. In both experiments, the attentional bias to fearful faces appeared to emerge between 5 and 7 months of age: 5‐month‐olds did not show a difference in disengaging attention from fearful and nonfearful faces, whereas 7‐ and 9‐month‐old infants had a lower probability of disengaging attention from fearful than nonfearful faces. Across the age groups, heart rate (HR) data (Experiment 1) showed a more pronounced and longer‐lasting HR deceleration to fearful than nonfearful expressions. The results are discussed in relation to the development of the perception and experience of fear and the interaction between emotional and attentional processes.     

Smallpox and Its Eradication in Finland: Implications for Disease Control

Cause-specific mortality studies are vital for a full understanding of the determinants of mortality and epidemiological transitions. The exceptional detail and accuracy of archival materials in Finland, as well as the length of the period covered, offer an ideal opportunity for such analyses. Focussing upon the late nineteenth and early twentieth centuries, the history, decline, and eventual eradication of smallpox is detailed. It has often been argued that primary vaccination in childhood was the major factor responsible for the decline and subsequent elimination of the disease in Finland. This perspective is probably correct for the initial decrease in smallpox mortality. To interpret the final phases of smallpox history in Finland, however, several factors must be taken into consideration. These include revaccination, virulence of the virus, containment (quarantine) of infected individuals, vaccination of contacts, and importation of the virus from surrounding countries. While these factors were not of equal causal importance, they exerted a synergistic effect on the course of Finnish smallpox history. This in-depth historical case study demonstrates that multiple factors must be taken into account when disease control policies in developing countries are formulated to-day.     

Community in a children's home

In this paper the focus is on ‘the community’ of a children's home and what it looks like from the children's point of view. The research data consist of ethnographic research material produced in conjunction with a doctoral thesis in 1996. The community was analysed in respect to four features: periodic adult relationships, alliance creation, importance of peers relationships and continuous negotiations, where children take active roles. In addition to periodic employees, the community of a children's home includes different relationships between peers and adults. The significance of the community is individually experienced. According to the field research, a children's home can offer home‐like experiences for some children and give a feeling of belonging, while there are also children for whom a sense of belonging is more complex. There is a need for a community approach in child protection and child welfare research. The studies of children's friendship and other human relationships provide adults and professionals with an understanding of the role of these relationships in the children's life and future. The studies also yield information on how these personal relationships are interpreted by young people.
