Shift Work,Role Overload,and the Transition to Parenthood

This article examines how the work hours, work schedules, and role overload of working‐class couples are related to depressive symptoms and relationship conflict across the transition to parenthood. Data are from 132 dual‐earner couples interviewed 5 times across the transition. Multilevel modeling analyses revealed that working evening or night shifts, as opposed to day shifts, was related to higher levels of depressive symptoms. For mothers only, working rotating shifts predicted relationship conflict. Increases in role overload were positively related to both depression and conflict; working a nonday shift explained variance in depression and conflict above and beyond role overload. Results suggest that for new parents, working nonday shifts may be a risk factor for depressive symptoms and relationship conflict.     

Paying for permanence: Public preferences for contaminated site cleanup

We use conjoint choice questions to investigate the preferences of people in four cities in Italy for income and future/permanent mortality risk reductions delivered by contaminated site remediation policies. The VSL is €5.6 million for an immediate risk reduction. If the risk reduction takes place 20 years from now, the implied VSL is €1.26 million. Respondents’ implicit discount rate is 7%. The VSL depends on respondent characteristics, familiarity with contaminated sites, concern about the health effects of exposure to toxicants, having a family member with cancer, perceived usefulness of public programs and beliefs about the goals of government remediation programs.

Pre-, post-, and longitudinal evaluation of juvenile justice education

This article describes two stages of the Juvenile Justice Educational Enhancement Program's pre-, post-, and longitudinal evaluation research. Pilot studies were used to explore how to design statewide research of pre- and postassessment scores and community reintegration outcomes. Preliminary findings suggest that higher performing educational programs produce greater educational gains as measured by academic achievement tests, credits earned, and pupil progression rates. The findings also indicate that these programs have more students returning to school and lower recidivism rates. Building on the pilot studies, refinements were made to the research designs to enable more comprehensive statewide evaluation. Current research includes collection of pre- and postassessment scores from official sources on approximately 16,000 juvenile justice youths. In addition, a research design has been developed to examine program effectiveness by measuring community reintegration variables. Multiple data sources, including official and self-reported data on family, school, employment, and subsequent crime involvement, will be used in the longitudinal study.     

Analysis of noise on construction sites of high-rise buildings

In the civil construction industry sector, it has been observed that the increasing use of machines has made tasks noisier and consequently caused hearing loss and had other adverse effects on workers. The objective of this study was to identify and assess the physical risks of noise present in activities undertaken in a construction company in order to propose control measures which will contribute to the management of health and safety within the company's organization. The methodology applied was based on verifying the characteristics of exposure to noise on construction sites, from an observation of sources which generated noise and making measurements of sound pressure levels emitted by these sources. The data was then analyzed and compared with the recommended performance levels established in control measures. As a result, it was found that some machines and equipment used in civil construction often generate noise above the acceptable levels and as such, in these cases, various control measures have been proposed. It is believed that the use of management techniques is the most effective way to assess risk and to implement the preventive and corrective actions proposed, and allows for the analysis of sound pressure levels on an ongoing basis.     

The correlation between thermal comfort in buildings and fashion products

This article is about thermal comfort in the wearable product. The research correlates fashion and architecture, in so far as it elects the brise soleil - an architectural element capable of regulating temperature and ventilation inside buildings - as a study referential, in trying to transpose and adapt its mechanisms to the wearable apparel.     

Reference database of hematological parameters for growing and aging rats

The normal hematological values in various phases of the rat life provide a valuable guide to researchers and could be useful for experimental works. However, database information available on the literature are incomplete. Aim: This study aimed to present normal hematological parameters of young and aged rats.

Methods: Male and female rats were distributed into seven experimental groups with 1, 2, 3, 6, 12, 18, and 24 months of age. Blood samples taken from the tails were analyzed. Normal hematological values were determined for each age group.

Results: Rats showed a progressive weight gain with advancing age, predominantly after 3 months of life. With advancing age, differences were found on hematological parameters: some of them showed a progressive rise with age and others did not. Hemoglobin levels and hematocrit did not change while the number of circulating red blood cells suffered slight increase.

Conclusion: The present study determined the normal values for absolute and relative hematological parameters in Wistar rats from 2 to 24 months for male and female rats. The results can be used in studies of effects of aging, feeding, and medications on growing and aging rats.     

Need for recovery from work and sleep-related complaints among nursing professionals

The concept of need for recovery from work (NFR) was deduced from the effort recuperation model. In this model work produces costs in terms of effort during the working day. When there is enough time and possibilities to recuperate, a worker will arrive at the next working day with no residual symptoms of previous effort. NFR evaluates work characteristics such as psychosocial demands, professional work hours or schedules. However, sleep may be an important part of the recovery process. The aim of the study was to test the association between sleep-related complaints and NFR. A cross-sectional study was carried out at three hospitals. All females nursing professionals engaged in assistance to patients were invited to participate (N = 1,307). Participants answered a questionnaire that included four sleep-related complaints (insomnia, unsatisfactory sleep, sleepiness during work hours and insufficient sleep), work characteristics and NRF scale. Binomial logistic regression analysis showed that all sleep-related complaints are associated with a high need for recovery from work. Those who reported insufficient sleep showed a greater chance of high need for recovery; OR=2.730 (CI 95% 2.074 - 3.593). These results corroborate the hypothesis that sleep is an important aspect of the recovery process and, therefore, should be thoroughly investigated.     

Minor psychiatric disorders among nursing workers--is there an association with current or former night work?

We aimed at analyzing whether Minor Psychiatric Disorders (MPD) is associated to night work either currently or in the past. A cross-sectional study was conducted at three public hospitals in Brazil, with female nursing workers. Data collection (N=1,134) was based on a comprehensive questionnaire that included the self-reported questionnaire (SRQ-20) for screening of MPD. Former night workers were subdivided into three groups according to their reasons for leaving night work: (i) directly related to work, (ii) related to better reconcile with studies or another job, and (iii) related to health, sleep, fatigue or stress. Binomial logistic regression was performed, with adjustment for potential confounders. A dose response gradient was observed between current night work and MPD (OR=1.5; 95% CI: 1.1-2.2 and OR=2.1; 95%CI: 1.5-3.1 for those who worked up to five nights and six or more nights per 2-week span, respectively). Potential detrimental effects of night work were confirmed. The association between working at night and MPD was not restricted to current night workers as workers who left night work for health/fatigue/sleep/strain also showed higher chances of reporting MPD (OR=1.8;95%CI:1.14-2.90). Results contribute to the scientific debate on the impact of night work on health and wellbeing.     

Réformes de l'immigration au Québec en 2019 et 2020: La logique politique à l’épreuve de l'analyse statistique

This research note examines the economic performance of economic immigrants selected under the Quebec Experience Program (PEQ). Launched in 2010 and currently being challenged by the Government of Quebec, this immigration program offers an accelerated path to obtaining a Quebec Selection Certificate. Drawing on data from The Longitudinal Immigration Database (IMDB), this analysis focuses on PEQ immigrants’ employment rates and employment income compared to the Quebec population aged 25 and 44, other economic immigrants admitted to Quebec, and candidates for the Canadian experience program admitted in another province. The results show that the first cohorts of this program performed very well on the Quebec job market, a performance that compares favorably with that of the other groups studied. The results indicate that the economic arguments put forward by the Québec Government to justify the reform of the PEQ do not withstand the statistical examination of employment outcomes; other factors should justify this reform.
