Childlessness and Psychological Well-Being in Midlife and Old Age: An Examination of Parental Status Effects Across a Range of Outcomes

The study explores and distinguishes links between parental status (childless persons, parents with residential children, and empty nest parents) and a range of psychological well-being outcomes in midlife and old age. Data are from the first wave of the Norwegian Life Course, Ageing and Generation (NorLAG) study (n = 5,189). We separate outcomes into cognitive (life satisfaction and self-esteem) and affective (positive and negative affect, depression, loneliness) components. Parental status has a net effect on cognitive well-being among women, as childless women report significantly lower life satisfaction and self-esteem than both mothers with residential children and empty nest mothers. However, motherhood is inconsequential for affective well-being. Among men, parental status is unrelated to any of the well-being aspects. Parental status effects are not modified by age, marital status, and education. The results demonstrate the importance of investigating the effect of parental status and other objective circumstances on a range of psychological well-being outcomes. Furthermore, the results reviewed and presented indicate somewhat more positive effects of parenthood in the Nordic countries than in the US, highlighting the role of social policies in shaping the impact of parental status on well-being.     

Investigating suburban micromoth diversity using DNA barcoding of malaise trap samples

Micromoths can be challenging to identify based on morphology and are frequently omitted in assessments of moth diversity. However, their species richness and biology make them important components of terrestrial ecosystems. In this study we identified 1227 micromoths from a suburban garden at 63° north using DNA barcoding of Malaise trap samples. We recorded 78 different species with the 11 most abundant taxa accounting for 82 % of the catch. The remaining 67 species were represented by fewer than 14 specimens, but the number was often sufficient to provide a good idea of phenology. The larvae of these 78 species all feed on plants common in suburban environments. We show that when facilitated by identifications through DNA barcoding, Malaise traps provide interesting insights into the micromoth communities of suburban environments that might otherwise be overlooked. The use of Malaise traps is beneficial for investigations at high latitudes where light trapping is inefficient for sampling moths due to bright summer nights.     

The power of discourse: Michel Foucault and critical theory

Abstract

The debate that contrasts Marxism and the work of Michel Foucault often overlooks that both projects share a political and ethical commitment. Both have moreover engaged that commitment by challenging what Marx called ‘traditional ideas’, viewing them as historically compilcit with the exercise of power. This ‘radical rupture’ with traditional ideas has been the hallmark of the critical theory project since The Communist Manifesto. By challenging traditional notions of power and language, however, Michel Foucault went further than the Marxist tradition in carrying out the critical theory project. Foucault's alternative ideas of discourse/practice and of power as ‘positive’ are moreover intricately linked in a way that has not been sufficiently appreciated. This is evident in a genealogy of Foucault's early work, where neither notion is able to take hold in the absence of the other. It only after The Archaeology of Knowledge, where Foucault rethought the relationship of language to reality, that he was able to formulate the notion of power as positive in works to come. This link should cause us to rethink our relationship to Foucault's work, of it to Marxism, and of the critical theory project to the power.     

Nutrient intake in day workers and shift workers

Abstract

The 24-h dietary intake, nutritional status parameters and psychosomatic factors of two-shift, three-shift and day workers were compared. Estimations of the dietary intake (across a work cycle) were made by use of a nutrient database. No significant differences were found between the groups for a large number of nutritional variables: intake of energy; intake and percentage of energy from protein, fat, total carbohydrates and sucrose; intake of coffee; and intake and density of vitamins and minerals. Only minor differences were found between the groups with regard to the quantitative intake of alcohol and calcium, and with regard to the quality of the diet (percentage of energy from alcohol, density of calcium). The groups differed significantly with respect to attitude towards work hours (three-shift workers being most negative in their attitude) and sleep disturbances (shift workers being most negative). The three-shift workers were more evening-oriented and they had higher concentrations of glucose in their blood. It was concluded that work hours not related to nutritional intake—at least not when total amounts across time are considered. It was also concluded that work hours were not related to Body Mass Index or blood lipids: triglycerides, total cholesterol, LDL (low-density lipoprotein) cholesterol and HDL (high-density lipoprotein) cholesterol.     

“How Exposed Is Exposed Enough?” Lay Inferences About Chemical Exposure

The concept of exposure is central to chemical risk assessment and plays an important role in communicating to the public about the potential health risks of chemicals. Research on chemical risk perception has found some indication that the model lay people use to judge chemical exposure differs from that of toxicologists, thereby leading to different conclusions about chemical safety. This paper presents the results of a series of studies directed toward developing a model for understanding how lay people interpret the concept of chemical exposure. The results indicate that people's beliefs about chemical exposure (and its risks) are based on two broad categories of inferences. One category of inferences relates to the nature in which contact with a chemical has taken place, including the amount of a chemical involved and its potential health consequences. A second category of inferences about chemical exposure relates to the pragmatics of language interpretation, leading to beliefs about the motives and purposes behind chemical risk communication. Risk communicators are encouraged to consider how alternative models of exposure and language interpretation can lead to conflicting conclusions on the part of the public about chemical safety.     

The perceived quality of life in Norway: Regional variations and contextual effects

This article deals with perceived quality of life and its relationship to sociodemographic background variables in Norway. We try to answer two questions, viz (1) to what extent does the absolute level of quality of life as well as the relationships between quality of life and individual-level sociodemographic variables vary between Norwegian counties? and (2) are such variations related to specific characteristics of the various counties? Some between-county variation is found, but in most cases the pattern of variation is not replicated across surveys. For variation in the absolute level of QOL as well as in the relationship between an individual's education and QOL, however, there is a moderate degree of stability. Contextual analyses show that the relationship between education and QOL is positive and moderately strong in affluent counties, near zero or negative in economically more backward areas. The results are interpreted within the framework of a person-environment fit model.     

Self-Efficacy,Pulmonary Function,Perceived Health and Global Quality of Life of Cystic Fibrosis Patients

This study examined the extent that pulmonary function is related to perceived health status and global quality of life in adults suffering from cystic fibrosis, and the extent that self-efficacy modifies these relationships. Our sample comprised 86 adults (48% female; mean age, 29 years; age range, 18–54 years) with cystic fibrosis, recruited from the Norwegian Competence Centre for Cystic Fibrosis (83% response rate). Both subjective data on psychosocial aspects of living with cystic fibrosis, and objective data on pulmonary function (FEV1%) were assessed. Psychosocial aspects were assessed by a questionnaire that included St George’s Respiratory Questionnaire (perceived health status), the Generalized Self-Efficacy Scale (perceived self-efficacy), and the Quality of Life Scale (global quality of life). We found that self-efficacy is an additional factor explaining health status and global quality of life. Pulmonary function is important for health status, but not for global quality of life, for which perceived self-efficacy and health status are the most significant variables. These results show that self-efficacy is as important as pulmonary function for the perceived health status and global quality of life of patients. These valuable findings should be considered in the treatment and care of adult patients suffering from cystic fibrosis.     

Yea-saying and mood-of-the-day effects in self-reported quality of life

This paper focuses on some of the complications that may arise from errors of measurement in quality of life (QOL) scales based on self-report. It is argued that systematic errors as well as random errors (specifically in the shape of mood-of-the-day effects) will tend to suppress, mask or “wash out” statistical associations between “objective”, sociologically relevant, indicators of well-being and self-reported quality of life. Results from a Norwegian sample of middle-aged and old participants in a health screening operation (N=610) are reported. The findings indicate that response acquiescence (“yea-saying”) may be a source of systematic error even in balanced QOL-scales, and that this bias may lead one to underestimate QOL among the well-educated and overestimate it among older respondents. Utilizing over-time data we are able to show that self-reported QOL appears particularly vulnerable to mood-of-the-day effects among younger females. Implications for sociological research on subjective well-being are pointed out.
