Parents,Perceptions and Belonging: Exploring Flexible Working among UK Fathers and Mothers

This paper advances knowledge regarding how fathers and mothers perceive and experience flexible working opportunities. It does this through applying the theoretical concept ‘belonging’ to ‘Parsonian’ classifications of parenting and work. In so doing it makes transparent the misconceptions and inequities which exist among parents and their organizational environments. Focusing initially on a qualitative study of fathers’ experience of working flexibly, the paper shows how fathers felt marginalized from the possibilities of flexible work due to line managers’ assumptions that men belonged to an ‘instrumental’ economic provider group. The paper contributes a new angle to debate by articulating how fathers perceived employed mothers as belonging to an ‘expressive’ child‐oriented group, with privileged access to flexibility. However, drawing upon a study of maternity and flexible work we query fathers’ assumptions that flexibility was easily available to mothers, suggesting that fathers’ perceptions of maternal privilege were misconceived. While mothers were categorized as belonging within an ‘expressive’ group associated with childcare, they were nevertheless discouraged from accessing flexibility. Inequities between women and men (with regard to flexibility) thus appeared to be less significant than fathers supposed.     

Evaluating Weight of Evidence in the Mystery of Balkan Endemic Nephropathy

Balkan endemic nephropathy (BEN) is a chronic, progressive wasting disease of the kidneys, endemic in certain rural regions of the Balkan nations Croatia, Serbia, Bulgaria, and Romania. It is irreversible and ultimately fatal. Though this disease was first described in the 1950s, its causes have been a mystery and a source of much academic and clinical contention. Possible etiologic agents that have been explored include exposure to metals and metalloids, viruses and bacteria, and the dietary toxins aristolochic acid (AA) and ochratoxin A (OTA). AA is a toxin produced by weeds of the genus Aristolochia, common in Balkan wheat fields. Aristolochia seeds may intermingle with harvested grains and thus inadvertently enter human diets. OTA is a mycotoxin (fungal toxin) common in many foods, including cereal grains. In this study, we analyzed the weight of evidence for each of the suspected causes of BEN using the Bradford Hill criteria (BHC): nine conditions that determine weight of evidence for a causal relationship between an agent and a disease. Each agent postulated to cause BEN was evaluated using the nine criteria, and for each criterion was given a rating based on the strength of the association between exposure to the substance and BEN. From the overall available scientific evidence for each of these suspected risk factors, AA is the agent with the greatest weight of evidence in causing BEN. We describe other methods for testing causality from epidemiological studies, which support this conclusion of AA causing BEN.     

Sensitivity Analysis for Critical Control Points Determination and Uncertainty Analysis to Link FSO and Process Criteria: Application to Listeria monocytogenes in Soft Cheese Made from Pasteurized Milk

Microbiological food safety is an important economic and health issue in the context of globalization and presents food business operators with new challenges in providing safe foods. The hazard analysis and critical control point approach involve identifying the main steps in food processing and the physical and chemical parameters that have an impact on the safety of foods. In the risk‐based approach, as defined in the Codex Alimentarius, controlling these parameters in such a way that the final products meet a food safety objective (FSO), fixed by the competent authorities, is a big challenge and of great interest to the food business operators. Process risk models, issued from the quantitative microbiological risk assessment framework, provide useful tools in this respect. We propose a methodology, called multivariate factor mapping (MFM), for establishing a link between process parameters and compliance with a FSO. For a stochastic and dynamic process risk model of in soft cheese made from pasteurized milk with many uncertain inputs, multivariate sensitivity analysis and MFM are combined to (i) identify the critical control points (CCPs) for throughout the food chain and (ii) compute the critical limits of the most influential process parameters, located at the CCPs, with regard to the specific process implemented in the model. Due to certain forms of interaction among parameters, the results show some new possibilities for the management of microbiological hazards when a FSO is specified.     

ECONOMIC SCIENCE AND POLITICAL INFLUENCE

When policymakers and private agents use models, the economists who design the model have an incentive to alter it in order to influence outcomes in a fashion consistent with their own preferences. I discuss some consequences of the existence of such ideological bias. In particular, I analyze the role of measurement infrastructures such as national statistical institutes, the extent to which intellectual competition between different schools of thought may lead to polarization of views over some parameters and at the same time to consensus over other parameters, and finally how the attempt to preserve influence can lead to degenerative research programs.     

UNEMPLOYMENT INSURANCE AND CULTURAL TRANSMISSION: THEORY AND APPLICATION TO EUROPEAN UNEMPLOYMENT

This paper emphasizes the two‐way causality between the provision of unemployment insurance and the cultural transmission of civicness. The returns to being uncivic are increasing in the generosity of unemployment insurance; but this generosity is decreasing in the number of uncivic individuals. In this context, I determine the evolution of preferences across generations and show that cultural heterogeneity is sustained over the long‐run. The dynamics of cultural transmission can generate a long lag between the introduction of unemployment insurance and an increase in people's willingness to live off government‐provided benefits. Hence, it offers an explanation to the ‘European unemployment puzzle’ due to the coexistence of generous unemployment insurance and low unemployment in the 1950s and 1960s.     

Tools for decision making under imprecise risk

Generalizing risk, imprecise risk is a situation where available objective information is expressible by a lower probability. We study properties of certain lower probabilities in metrizable spaces. Necessary and sufficient conditions are derived for stability of their cores under image and mixture, which are useful features in applying Expected Utility Theory under imprecise risk.

Extremely Premature and Very Low Birthweight Infants: A Double Hazard Population?

This article evaluates the contributions of birth status (defined by gestational age and birthweight) and family adversity at birth and at age 7 to explaining behavior problems at age 7. The behaviors of 96 extremely preterm and very low birth‐weight children and 66 full‐term children were assessed in a school setting by peers, teachers and parents. The results show that a significant relationship exists between birth status and isolation and social withdrawal problems as well as between birth status and social immaturity and inattention problems. Family adversity at birth has a significant contribution to aggressive behaviors reported by the three sources whereas, at age 7, this index is associated only with aggressive behaviors and social immaturity problems reported by parents. In conclusion, the results of the present study qualify the findings of studies that suggest that at school age, the effect of prematurity decreases and that behavior problems are explained chiefly by family environment characteristics. Our results indicate that the findings must take into account the cohort studied, the environmental measures used, the type of behaviors assessed as well as the type of informants.     

The Effects of Marital Conflict and Marital Disruption on Depressive Affect: A Comparison Between Women In and Out of Poverty*

Objectives. We examine the independent and interactive effects of marital conflict and marital disruption on women's depressive affect and how these effects vary by family's poverty status. Methods. We use the OLS regression and data from the National Longitudinal Survey of Youth to test the hypothesized relationships. Results. The results showed that marital conflict and marital disruption each predicts subsequent depression after controlling for the initial level of depression and other antecedent variables. The effect of marital conflict on depression is stronger among women in poverty than those out of poverty. Furthermore, among women in poverty, marital conflict followed by marital breakup is related to a heightened level of depression, whereas among women financially better off, there is a reduction in the level of depressive affect. Conclusions. These findings point to the importance of a family's economic condition and its impact on the interrelationships among marital processes and women's psychological health.     

Of Roots and Wings: Letting Go of the College‐Bound Child

This article examines how parents experience the process of “letting go” of their college‐bound children. The focus of our analysis is on how the parents evaluate the meanings of their children's leaving home and adopt strategies to facilitate the process for both themselves and the departing child. Our analysis is based on interviews with thirty sets of parents. The interview materials allowed us to recognize and then parse the paradoxical task faced by parents of fostering “attached individuation” for both themselves and their children. We address four broad and persistent themes that emerged from our conversations with parents. First, we consider how parents manage the range of sometimes‐conflicting emotions generated by the letting go process. Second, we analyze the content of parents' worries as a good unobtrusive measure of how they understand the transition to college as a ritual marker in their children's lives. Third, we show how negotiations about geography—about proper distance from home—in choosing a college reflect efforts to impose a measure of gradualism into the letting go process. Fourth, we report on how parents theorize the impact of a child's departure on family relationships in general.
