Conditional Information in Projections of Gaussian Vectors

Conditional information measures the information in a sample for an interest parameter in the presence of nuisance parameter. In the context of Gaussian likelihoods this paper first derives conditions under which a projection of the data may reduce conditional information to zero. These are then applied in the context of time series regressions, and inference on a covariance parameter, such as with either autoregressive or moving average errors. It is shown that regressing out very common regressors, such as a linear trend or dummy variable, can imply that conditional information is zero in the case of non-stationary autoregressions or non-invertible moving averages, respectively.     

Induced inefficiency as a response to the union threat

Milkman and Mitchell (1995) extend Rosen’s (1969) threat-effect hypothesis to suggest that the threat of unionization can induce inefficient underutilization of labor by nonunion firms. If firms follow this strategy, the apparent paradox of competitive coexistence in the face of higher union wages reflects induced nonunion firm inefficiency rather than superior union firm efficiency. Furthermore, this strategy decreases demand for nonunion workers in a partially unionized industry. A generalized cost function analysis of data from sawmills in the Pacific Northwest yields evidence that nonunion firms use this strategy.     

Helping mothers to combine paid and unpaid work–or fighting unemployment? the ambiguities of french family policy

The Family Law' passed by the French Parliament in July 1994 introduced important changes in family policy. Because the number of publicly subsidised childcare places is still very limited, and to encourage families to create employment (by employing childcare workers), the government has chosen to encourage the development of a variety of childcare provisions by increasing the financial incentives payable to parents employing a private nanny or child-minder. The same rationale of reducing unemployment has also prompted the decision to extend existing child rearing benefit to families having a second child. This measure has been very successful in encouraging women to retire from the labour market. The high cost of these changes has been shared by Social Security and the State. However, the changes have contributed to the increased polarisation between higher and lower wages families, with highly qualified mothers, who can afford childcare costs, remaining in paid employment after giving birth, and lower qualified mothers leaving the labour market.     

Merton’s Sociology 215-216 Course

For many years, Robert K. Merton taught a famous, year-long graduate course at Columbia called The Analysis of Social Structures. His lectures have been recalled for their dazzling intellectual effects by those who took the course, but none of these former students has described what Merton actually said in specific lectures. I do this now, using my extensive lecture notes from 1952–53 when I took it for credit, and from later years when I sat in on the course. The core of the course at that time was Merton’s Paradigm for Functional Analysis in Sociology. Each concept in the paradigm—subjective dispositions, objective consequences, functional requirements, structural constraints, etc.—was elaborated in its relationship to a wide variety of sociological problems in the published theoretical and empirical literature. I also recount how Merton’s relationship to Talcott Parsons appeared to us in the course.     

Six‐ and 9‐Month‐Old Infants Discriminate Between Goals Despite Similar Action Patterns

Behne, Carpenter, Call, and Tomasello (2005) showed that 9‐ to 18‐month‐olds, but not 6‐month‐olds, differentiated between people who were unwilling and unable to share toys. As the outcome of the two tasks is the same (i.e., the toy is not shared), the infants must respond to the different goals of the actor. However, visual habituation paradigms have shown an earlier onset of goal awareness. The present study reconciles this disparity by replicating the findings of Behne et al. with both 6‐ and 9‐month‐olds, using similar tasks and additional response measures.     

Learning by doing: the case of administrative policy transfer in China

This article explores of the role of policy transfer in facilitating the rise and consolidation of the ‘Reform and Open Door Policy' in China. It builds upon the seminal Dolowitz and Marsh [Dolowitz, D., and D. Marsh. 1996. “Who Learns What From Whom: A Review of the Policy Transfer Literature.” Political Studies 44: 343–357; Dolowitz, D., and D. Marsh. 2000. “Learning from Abroad: The Role of Policy Transfer in Contemporary Policy-Making.” Governance 13 (1): 5–23] framework to provide an examination of processes of administrative policy transfer which it argues are broadly indicative of the dynamics of change underpinning the incremental process of reform. It is observed that the reforms under study have not been characterized by rational policy design underpinned by evidence-based policy-making in which issues of cultural assimilation were emphasized. Rather, the implementation process itself has been used to affect processes of adaptation. Policy transfer in China can best be described as learning by doing.     

Psychological Distress of Cuban Americans Affected by Restrictive U.S. Travel Policies

We describe the mental health consequences of United States travel policies affecting Cuban Americans (CAs) with relatives in Cuba and discuss these policies in the context of U.S. domestic politics and the Bush administration's desire for regime change in Cuba. Policies put into effect in 2004 restrict CAs from visiting relatives in Cuba more than once every 3 years, narrowly define family whom CAs can legally visit, and limit the assistance they can provide their Cuban relatives. We share case reports based on qualitative interviews with 53 Cuban Americans that illustrate travel-related psychological distress (TRPD) experienced by CAs in response to the restrictions. We note the difficulties CAs experience in coping with TRPD and the need for political and mental health interventions to address this condition. TRPD is directly related to the government's violation of the human and constitutional rights of CAs to travel freely. It is the responsibility of the state to restore those rights. Human services professionals should oppose TRPD as antithetical to family well-being.
