Families Created by the New Reproductive Technologies: Quality of Parenting and Social and Emotional Development of the Children

Abstract: The creation of families by means of the new reproductive technologies has raised important questions about the psychological consequences for children, particularly where gamete donation has been used in the child's conception. Findings are presented of a study of family relationships and the social and emotional development of children in families created as a result of the 2 most widely used reproductive technologies, in vitro fertilization (IVF) and donor insemination (DI), in comparison with control groups of families with a naturally conceived child and adoptive families. The quality of parenting was assessed using a standardized interview with the mother, and mothers and fathers completed questionnaire measures of stress associated with parenting, marital satisfaction, and emotional state. Data on children's psychiatric state were also obtained by standardized interview with the mother, and by questionnaires completed by the mothers and the children's teachers. The children were administered the Separation Anxiety Test, the Family Relations Test, and the Pictorial Scale of Perceived Competence and Social Acceptance. The results showed that the quality of parenting in families with a child conceived by assisted conception is superior to that shown by families with a naturally conceived child. No group differences were found for any of the measures of children's emotions, behavior, or relationships with parents. The findings are discussed in terms of their implications for understanding the role of genetic ties in family functioning and child development.

What do we mean by performativity in organizational and management theory? The uses and abuses of performativity.

Abstract: John Austin introduced the formulation ‘performative utterance’ in his 1962 book How to Do Things with Words. This term and the related concept of performativity have subsequently been interpreted in numerous ways by social scientists and philosophers such as Lyotard, Butler, Callon and Barad, leading to the coexistence of several foundational perspectives on performativity. This paper reviews and evaluates critically how organization and management theory (OMT) scholars have used these perspectives, and how the power of performativity has, or has not, stimulated new theory-building. In performing a historical and critical review of performativity in OMT, the authors’ analysis reveals the uses, abuses and under-uses of the concept by OMT scholars. It also reveals the lack of both organizational conceptualizations of performativity and analysis of how performativity is organized. Ultimately, the authors’ aim is to provoke a ‘performative turn’ in OMT by unleashing the power of the performativity concept to generate new and stronger organizational theories.

Is More Finance Better? Disentangling Intermediation and Size Effects of Financial Systems

Abstract: Financial systems all over the world have grown dramatically over recent decades. But is more finance necessarily better? And what concept of finance – the size of the financial sector, including both intermediation and other auxiliary 'non-intermediation' activities, or a focus on traditional intermediation activity – is relevant for its impact on real sector outcomes? This paper assesses the relationship between the size of the financial system and the degree of intermediation, on the one hand, and GDP per capita growth and growth volatility, on the other hand. Based on a sample of 77 countries for the period 1980-2007, we find that intermediation activities increase growth and reduce volatility in the long run. An expansion of the financial sectors along other dimensions has no long-run effect on real sector outcomes. Over shorter time horizons a large financial sector stimulates growth at the cost of higher volatility in high-income countries. Intermediation activities stabilize the economy in the medium run especially in low-income countries.

Dynamics of water droplets detached from porous surfaces of relevance to PEM fuel cells.

Abstract: The detachment of liquid droplets from porous material surfaces used with proton exchange membrane (PEM) fuel cells under the influence of a cross-flowing air is investigated computationally and experimentally. CCD images taken on a purpose-built transparent fuel cell have revealed that the water produced within the PEM is forming droplets on the surface of the gas-diffusion layer. These droplets are swept away if the velocity of the flowing air is above a critical value for a given droplet size. Static and dynamic contact angle measurements for three different carbon gas-diffusion layer materials obtained inside a transparent air-channel test model have been used as input to the numerical model; the latter is based on a Navier-Stokes equations flow solver incorporating the volume of fluid (VOF) two-phase flow methodology. Variable contact angle values around the gas-liquid-solid contact-line as well as their dynamic change during the droplet shape deformation process, have allowed estimation of the adhesion force between the liquid droplet and the solid surface and successful prediction of the separation line at which droplets loose their contact from the solid surface under the influence of the air stream flowing around them. Parametric studies highlight the relevant importance of various factors affecting the detachment of the liquid droplets from the solid surface.

Employment and the family : the reconfiguration of work and family life in contemporary societies

Abstract: Rates of employment amongst mothers of young children have risen rapidly in recent years. Attitudes to gender roles have changed, and both employers and governments have had to adjust to new realities. But some argue that recent changes in employment relations are making work more family 'unfriendly'. What are the real consequences of change? Rosemary Crompton explores the origins and background of this radical shift in the gendered division of labour. Topics covered include the changing attitudes to gender roles and family life, the gendered organisational context, and recent changes in employment relations and their impact on work-life articulation. A comparative analysis of Britain, France, Norway, Finland, the United States and Portugal provides an assessment of the varying impact of state policies, and the changing domestic division of labour. Crompton draws on original research and situates her findings within contemporary theoretical and empirical debates.
