POSTMORTEM POLITICS

This article discusses the connection between the political behaviour model of bereavement in Israel and the ability of the military to preserve its hegemonic standing under a veil of secrecy unchallenged by civil criticism. After the War of Independence (1948), with its heavy military death toll, a model of hegemonic bereavement made its appearance. A nationalist/collectivist ideology geared to nation‐building fostered widespread support of government institutions and mobilized grief on its behalf. In this framework, the activities of bereaved parents were channelled by the state to public sites and commemoration practices, and bereavement was, in effect, nationalized. After the Yom Kippur War (1973), and following the Lebanese incursion of 1982, a political bereavement model became dominant. Parents assigned guilt for the death of their sons to the formulators of security policy – principally the Defense Minister and the Prime Minister – and engaged in media and political activities against the state. In the 1990s, following a revolution in the media and the law, the awareness of liberal values and the beginnings of a peace agreement with the Palestinians, bereaved parents whose sons had been killed in training accidents and military failures adopted a model of confrontation bereavement vis‐á‐vis the army. They engaged in public activity aimed at exposing the army to civilian criticism. The article looks at the three models and the responses of the military to each one. It appears that a close connection exists between the dominant bereavement model, the quality of army and societal relations in Israel, and the degree of transparency of the military.     

Relationship Characteristics and Risk of HIV Infection: Rusbult's Investment Model and Sexual Risk Behavior of Gay Men in Steady Relationships1

This study examined the effects of relationship characteristics, as measured by Rusbult's (1980) investment model, on safer‐sex behavior between steady gay male partners. Analyses showed that low satisfaction with the relationship was associated with more risky unprotected anal intercourse (UAI). High commitment to the relationship was associated with more practice of negotiated safety (i.e., having safe UAI after both partners have tested negative for HIV and have reached sexual safety agreements). High relationship investment was associated with more risky UAI (borderline significant). We conclude that using relationship satisfaction, commitment, and investment as co‐determinants of sexual risk behavior could prove useful in the development of new HIV‐prevention strategies for gay men in relationships.     

Randomized Trial Comparing Two Treatment Strategies Using Prize-Based Reinforcement of Abstinence in Cocaine and Opiate Users

We compared two strategies of prize-based contingency management (CM) in methadone-maintained outpatients. Urine was tested thrice weekly for 5 weeks pre-CM, 12 weeks CM, and 8 weeks post-CM. Participants were randomly assigned to a cocaine contingency (four prize draws for each cocaine-negative urine, N  =  29) or an opiate-cocaine contingency (one draw for each urine negative for opiates or cocaine, four draws if negative for both, N  =  38). There were no group differences in cocaine abstinence during CM or post-CM and no differences in opiate abstinence during CM. Opiate abstinence was greater in the opiate-cocaine group post-CM, and heroin craving was reduced in this group during and post-CM. Draws earned per cocaine-negative urine (four vs. one) did not affect cocaine use.     

Comparing Computational Power

It is common practice to compare the computational power ofdifferent models of computation. For example, the recursivefunctions are strictly more powerful than the primitive recursivefunctions, because the latter are a proper subset of the former(which includes Ackermann's function). Side-by-side with this"containment" method of measuring power, it is also standardto base comparisons on "simulation". For example, one says thatthe (untyped) lambda calculus is as powerful—computationallyspeaking—as the partial recursive functions, because thelambda calculus can simulate all partial recursive functionsby encoding the natural numbers as Church numerals. The problem is that unbridled use of these two distinct waysof comparing power allows one to show that some computationalmodels (sets of partial functions) are strictly stronger thanthemselves! We argue that a better definition is that modelA is strictly stronger than B if A can simulate B via some encoding,whereas B cannot simulate A under any encoding. We show thatwith this definition, too, the recursive functions are strictlystronger than the primitive recursive. We also prove that therecursive functions, partial recursive functions, and Turingmachines are "complete", in the sense that no injective encodingcan make them equivalent to any "hypercomputational" model.¹     

EFFECT OF REINFORCEMENT PROBABILITY AND PRIZE SIZE ON COCAINE AND HEROIN ABSTINENCE IN PRIZE‐BASED CONTINGENCY MANAGEMENT

Although treatment outcome in prize‐based contingency management has been shown to depend on reinforcement schedule, the optimal schedule is still unknown. Therefore, we conducted a retrospective analysis of data from a randomized clinical trial (Ghitza et al., 2007) to determine the effects of the probability of winning a prize (low vs. high) and the size of the prize won (small, large, or jumbo) on likelihood of abstinence until the next urine‐collection day for heroin and cocaine users (N = 116) in methadone maintenance. Higher probability of winning, but not the size of individual prizes, was associated with a greater percentage of cocaine‐negative, but not opiate‐negative, urines.     

The Emotional Reengineering of Loss: On the Grief-Anger-Social Action Continuum

This article deals with the role of bereaved parents' anger as a motivating force for political and public activism. After reviewing the place of anger in the experience of processing loss and bereavement and presenting anger as a factor that leads to public initiative, the article deals with the place that anger occupies in the bereaved sector of Israeli society. The claim is made that Israeli society has changed since its early years, when "the national management of emotions" did not allow anger to be present in the public discourse of bereaved parents, to the current era in which anger is an inseparable part of Israeli bereavement discourse. The following section of the article includes an interpretive analysis of the place of anger among the research subjects, bereaved parents who later became public and political entrepreneurs. All of the research subjects lost a son in one of three circumstances that are part of the Israeli security agenda: operational accidents, terrorist attacks, and IDF combat in Lebanon. Finally, the study attempts to answer how anger structures both public and private bereavement in Israel, shaping the bereaved parents as instant celebrities.     

Web-based, psychosocial treatment for substance use disorders in community treatment settings

The purpose of this multisite clinical trial was to evaluate the effectiveness of a web-based version of the Community Reinforcement Approach, plus motivational incentives, within community-based, outpatient substance abuse treatment. This ongoing study is being conducted within the National Drug Abuse Treatment Clinical Trials Network, funded by the National Institute on Drug Abuse. Midway through the enrollment of 500 participants, the study is being implemented in 10 treatment programs across the United States. Information is provided on design, sample, intervention and technology, and preliminary lessons learned.
