Indefinite terminating points and the iterated Prisoner's Dilemma

Conclusion In conclusion, I shall indicate one consequence of (3.4). The major resultof work on infinitely iterated Prisoner's Dilemma games is that there existcooperative equilibria in such games. I have suggested above that myaccount of finitely, but indefinitely, iterated Prisoner's Dilemma gamesreflects the nature of genuine iterated Prisoner's Dilemmas more accu-rately than accounts involving infinite iterations. If my suggestion iscorrect, then one consequence of (3.4) - of there being only uncooperativeequilibria in finitely, but indefinitely, iterated games - is to call intoquestion the significance of the existence of cooperative equilibria ininfinitely iterated Prisoner's Dilemma games.Thanks to Jules Coleman, Mark Isaac, John Pollock, and Gregory Karva for helpful comments on earlier versions of this paper. Some of these results were presented as part of similar papers given at the 1986 meeting of the society for Exact Philosophy and at Bowling Green University.     

The Supreme Court and the Constitutional Convention

The cornerstone of sound social studies pedagogy is the ability of teachers to use materials that spur students to think critically, reflect honestly, and to participate purposefully and passionately. This article illustrates how elementary teachers can use select children's literature that prompts students to think critically about their geographic surroundings and encourages student-centered reflection and action.     

Methods for gauging the target populations that community colleges serve

For many community colleges, expanding enrollment demands coincide with shrinking resources, confronting policymakers with multiple competing constituencies of discouraged college-goers. At issue are whether community college enrollments are keeping pace with local growth among the subpopulations that typically attend community colleges; how enrollment levels might differ had participation rates remained unchanged; and which specific population groups, in which subareas of an overall region, are most affected by funding constraints. These issues focus attention on identifying and measuring the diverse populations such colleges serve. We present methods for tracking those populations (1) to gauge how completely (or incompletely) the local community college-going population is enrolling in various campuses, and (2) to delineate the functional service areas of individual campuses. Our methods have applicability to the needs of community college systems generally, especially where the size and geographic distribution of their populations are changing significantly through, for example, immigrant influx and regional expansion. These methods and measures add to the applied demographer’s repertoire of techniques for strengthening local decision-making.     

Therapeutic management of violence in residential care for severely mentally ill clients: An application of intrapsychic humanism∗

The innovative psychology, intrapsychic humanism, is applied to formulate guidelines for effectively managing violent symptoms of severely mentally ill clients in residential settings, with the aims of: 1) helping staff reduce client violence; and 2) helping clients regulate their violent behavior. Using intrapsychic humanism, staff can understand, anticipate, and respond therapeutically to client violence. Triggers of violence, such as aversive reactions to pleasure and destructive reactions to real losses are described. Residential program structures that strengthen clients’ constructive motives and staff's caregiving motives are outlined.     

SYMBOLIC INTERACTION AND SOCIAL POLICY ANALYSIS*

This paper explores the contribution that interactionist approaches may make to the study and understanding of social policy based on a discussion of: (1) the general orientation of the interactionist line on inquiry and the general assumptions which the theoretical stance makes about the character of the world, (2) the problems that are of primary interest to those who work within this perspective, and (3) the methodological and technical aspects of this approach. Fruitful foci for basic and applied research from the interactionist perspective include: (1) how policy is constructed through negotiation within a structural context, (2) the multiple interpretations of policy intent and implementation, (3) the experience and meaning of social “problems” for those who are the intended objects of the social policies, and (4) the consequences of policies for the social order. Some of the major properties of the social policy context (uncertainty, decentralization, and political pluralism) are explored for their relevance to social policy analysis. Finally, we discuss the contribution of an institutional-contextual-social worlds approach as a macro-micro bridging mechanism in social policy studies.     

Alligators in the sewer,dragons in the well and Freud in the toilet

One of the most popular of all urban legends is the story about alligators in the sewers of New York (abbreviated AIS story). While previous investigations have been concerned with the historical origins of AIS stories, this article is concerned with developing a psychoanalytic explanation which accounts for the continuing popularity of such stories. In developing such an explanation, this article makes use of the association between‘penis’ and ‘feces,’ an association that is very likely among the earliest associations formed in the human mind. Given the penis = feces association, and given Freud's suggestion that the young child will typically take defecation as a model for castration, it is argued that AIS stories are ultimately concerned with castration. The fact that ‘castration’ has different connotations for males and females helps to explain some of the details invariably incorporated into an AIS story. Finally, the argument developed in connection with modern AIS stories is used to provide a new perspective upon traditional English stories about dragons.     

Weak convergence of bounded influence regression estimates with applications to repeated significance testing

We obtained weak convergence results for bounded influence regression M-estimates and apply the results to sequential clinical trials, with special reference to repeated significance tests in the two-sample problem with covariates.     

Assessing the Height of Mobility Barriers: A Methodology and an Empirical Test in the UK Retail Grocery Industry1

A profitable niche will have few entrants if the presence of significant mobility barriers impedes entry and, hence, reduces the expected rents for entrants. Identifying sources of mobility barriers is critical in explaining how incumbents can sustain competitive advantage and obtain supranormal profits (excess rents). While much of strategic management research (and strategic group research, in particular) focuses on the pursuit of sustainable performance advantages, there is relatively little empirical research exploring the dynamics of firm movement and the impact of mobility barriers on performance. The paper analyses mobility dynamics and, most importantly, develops a method to identify the location and severity of mobility barriers. The method is illustrated on a database of large multiples in the UK retail grocery industry for the period 1982–1986. It appears that there are two dimensions of strategic change that facilitate movement into profitable niches. Implications for competition and profitability are discussed.     

Adoption Now: a joint initiative of New York's courts and child welfare system

In November 2002, Chief Judge Judith Kaye attended the National Adoption Day festivities in Albany County and New York County (Manhattan). Although pleased that 600 adoptions were being finalized statewide on this special day, she was concerned to learn more than 6,000 other children were free for adoption but had not yet found permanent families. Judge Kaye reached out to New York State Office of Children and Family Services (OCFS) Commissioner John A. Johnson and New York City Administration for Children's Services (ACS) then-Commissioner William Bell to come together and begin a discussion to identify and resolve systemic barriers to adoption. At a press conference in May 2003, Chief Judge Kaye, Governor Pataki, New York City Mayor Bloomberg, and Judges and Commissioners representing counties from across the state announced the Adoption Now initiative that set a goal of finalizing adoptions for 5,000 children (3800 in New York City and 1200 upstate) by the end of 2003.
