Between policy and practice: Japan's Silver Human Resource Centers as viewed from the inside

The Silver Human Resource Centers (SHRC) were first established in 1980 to address the economic and psychological needs of Japan's growing numbers of senior citizens. The Centers, through which people are introduced to jobs in their locales and from which they receive remuneration for services performed, are by now well established throughout Japan. This article examines the gap between SHRC members' evaluations of the Centers and the Center guidelines, as stated in their published literature and in interviews with program administrators. The analysis is fourfold: (1) it explores the members' reasons for participating in the program; (2) it discusses their assessments of it; (3) it examines gender and social class differences in program planning and participation; and (4) it analyzes the Ministry of Labor's plan for new directions for the Centers. Although new policy directions do address many members' concerns, they do not attempt to question or change the status quo of the gendered division of labor in Japanese society.     

All Ages and None: Commentary on Helene Moglen's Ageing and Transageing

Helene Moglen's article is especially welcome, given the paucity of psychoanalytic reflection on ageing. She usefully describes possible ways of managing the losses of ageing through accessing the multiple, decentered self-states embedded in our personal histories. However, I have some queries on her use of contrasting psychic topologies. In particular I wonder whether she is sometimes in danger of seeing images of former selves as being associatively “recovered” in the work of mourning that might be better seen as the more illusive “production” of presumptively anterior contexts and states of mind in the present. I also question how successfully Moglen's positioning of her notion of “transaging” somewhere between “transgender” and “transsexuality” serves to loosen up the vicious binary between “young” and “old. I would appreciate closer attention to the dreaded “feminization” of old age, noting the toxic sexism permeating cultures of ageing. Nevertheless, Moglen offers an excellent opening into this troubling topic.     

How Security Agencies Control Change: Executive Power and the Quest for Autonomy in the FBI and CIA

The US Federal Bureau of Investigation and the Central Intelligence Agency gain autonomy when they exercise executive power, performing tasks that are so urgent, secretive, or forceful that they cannot be anticipated by law. The FBI exhibited a clear instance of autonomy when, with a view to its long term responsibilities, it resisted remaking itself as a counterterrorism agency to the degree that politicians requested. The second case, involving the CIA, produced more mixed results. The agency appeared to exhibit autonomy by exercising its powerful security tasks, including control over information and covert operations, and by resisting a consensus for major organizational change. Nevertheless, its large number of administrative and analytical rather than executive tasks prevented the agency from developing the coherent, independent perspective necessary for a high degree of true autonomy.

Kernel Density Estimator From Ranked Set Samples

We study kernel density estimator from the ranked set samples (RSS). In the kernel density estimator, the selection of the bandwidth gives strong influence on the resulting estimate. In this article, we consider several different choices of the bandwidth and compare their asymptotic mean integrated square errors (MISE). We also propose a plug-in estimator of the bandwidth to minimize the asymptotic MISE. We numerically compare the MISE of the proposed kernel estimator (having the plug-in bandwidth estimator) to its simple random sampling counterpart. We further propose two estimators for a symmetric distribution, and show that they outperform in MISE all other estimators not considering symmetry. We finally apply the methods in this article to analyzing the tree height data from Platt et al. (1988 Platt, W.J., Evans, G.M., Rathbun, S.L. (1988). The population dynamics of long-lived conifer (Pinus plaustris) (1988). Amer. Natrualist 131:491–525.[Crossref], [Web of Science ®] , [Google Scholar]) and Chen et al. (2003 Chen, Z., Bai, Z., Sinha, B.K. (2003). Ranked Set Sampling: Theory and Applications. New York: Springer. [Google Scholar]).

Models of the future

Existing world models are criticized for the omission of feedback effects. Modifications to existing models are considered implausible, and a very simple structure representing the system by stocks and flows of energy is proposed. The planning implications of such simple models are explored in terms of risk evaluation. The analysis of a possible risk situation yields a dimensionless quantity relating capital investment, depletion rate, investment fraction and efficiency. This quantity is shown to be critical in determining the existence of discontinuities in the growth curve, independent of the desired level of growth.
