Basic and Refined Nomic Truth Approximation by Evidence-Guided Belief Revision in AGM-Terms

Straightforward theory revision, taking into account as effectively as possible the established nomic possibilities and, on their basis induced empirical laws, is conducive for (unstratified) nomic truth approximation. The question this paper asks is: is it possible to reconstruct the relevant theory revision steps, on the basis of incoming evidence, in AGM-terms? A positive answer will be given in two rounds, first for the case in which the initial theory is compatible with the established empirical laws, then for the case in which it is incompatible with at least one such a law.     

The fallacy of intimacy: sexual risk behaviour and beliefs about trust and condom use among men who have sex with men in South Africa

The objective of this study is to assess (1) whether beliefs about trust and condom use affect sexual risk behaviour, and (2) if beliefs about trust and condom use impact sexual risk behaviour directly or if this relationship is mediated by other determinants. The Information-Motivation-Behavioural Skills model was used as a framework for the mediation analysis. A diverse cohort of three hundred 18-40 year old men who have sex with men (MSM) residing in Pretoria, South Africa, were recruited and surveyed for this project. Findings indicate that men who report a high frequency of past unprotected anal intercourse are more likely to believe that it is not necessary to use condoms with a trusted or steady partner regardless of their current partnership status. This fallacy of intimacy appears to affect sexual risk behaviour through intentions and attitudes regarding safer sex practices. Based on these findings, we recommend that more attention be given in gaining a better understanding of how beliefs about trust and condom use are formed and how they can be changed among MSM in South Africa.     

Reason and Love: A Non-Reductive Analysis of the Normativity of Agent-Relative Reasons

Why do agent-relative reasons have authority over us, reflective creatures? Reductive accounts base the normativity of agent-relative reasons on agent-neutral considerations like ‘having parents caring especially for their own children serves best the interests of all children’. Such accounts, however, beg the question about the source of normativity of agent-relative ways of reason-giving. In this paper, I argue for a non-reductive account of the reflective necessity of agent-relative concerns. Such an account will reveal an important structural complexity of practical reasoning in general. Christine Korsgaard relates the rational binding force of practical reasons to the various identities or self-conceptions under which we value ourselves. The problem is that it is not clear why such self-conceptions would necessitate us rationally, given the fact that most of our identities are simply given. Perhaps, Harry Frankfurt is right in arguing that we are not only necessitated by reason, but also, and predominantly by what we love. I argue, however, that “the necessities of love” (in Frankfurt’s phrase) are not to be separated from, but should be seen as belonging to the necessities of reason. Our loves, concerns and related identities provide for a specific and important structure to practical reflection. They function on the background of reasoning, having a specific default role: they would lose their character as concerns, if there was a need for them to be cited on the foreground of deliberation or if there was a need to justify them. This does not mean that our deep concerns cannot be scrutinised. They can only be scrutinised in an indirect way, however, which explains their role in grounding the normativity of agent-relative reasons. It appears that this account can provide for a viable interpretation of Korsgaard’s argument about the foundational role of practical identities.     

Undermining trust and cooperation: The paradox of sanctioning systems in social dilemmas

Sanctioning systems in social dilemmas are often meant to increase trust in others and to increase cooperation. We argue, however, that sanctioning systems may also give people the idea that others act in their own self-interest and undermine the belief that others are internally motivated to cooperate. We developed the “Removing The Sanction” paradigm and a new trust manipulation, and showed in three experiments that when there is a sanction on defection, trust in others being internally motivated to cooperate is undermined: Participants who had experienced the presence of a sanctioning system trusted fellow group members less than participants who had not. In a similar vein, the sanction undermined cooperation when trust was initially high. The implications of these paradoxical findings are discussed.     

Psychiatric nurses' attitudes towards inpatient aggression: preliminary report of the development of attitude towards aggression scale (ATAS)

Professional skills to adequately manage patient aggression are a prerequisite for nurses working in psychiatric hospitals. These ‘technical’ skills, however, are necessary but not sufficient for effective nurse intervention. The attitude of nurses' towards client aggression also contributes to their response to a patient's behaviour. In order to study the domains (types) of attitudes towards aggression, a sample was taken of nurses working in the fields of general psychiatry (n=288), psychiatry for children and adolescents (n=242) and psychogeriatrics (n=88). A cross‐sectional survey design was adopted for the study. The Attitudes Towards Aggression Scale (ATAS) consisting of 32 items is presented, representing three types of attitudes towards aggression: aggression as a ‘harming’ reaction, a ‘normal’ reaction and a ‘functional’ reaction. The strongest predictors of the type of attitude respondents had towards the aggressive behaviour of their clients were (1) field, (2) setting they worked in, (3) gender and (4) type of shifts they predominantly had. Although the measure of domains of nurses' attitudes towards aggression needs further psychometric testing, it can be a useful tool in clinical practice for the assessment of staff attitudes towards aggression. This can support the decision‐making about the management of aggressive behaviour on a ward. Aggr. Behav. 00:1–10, 2005. © 2005 Wiley‐Liss, Inc.     

Born to adapt, but not in your dreams

The brain adapts to changes that take place in the body. Deprivation of input results in size reduction of cortical representations, whereas an increase in input results in an increase of representational space. Amputation forms one of the most dramatic disturbances of the integrity of the body. The brain adapts in many ways to this breakdown of the afferent–efferent equilibrium. However, almost all studies focus on the sensorimotor consequences. It is not known whether adaptation takes place also at other “levels” in the system. The present study addresses the question whether amputees dream about their intact body, as before the amputation, or about the body after the amputation and whether the dream content was a function of time since the amputation and type of amputation. The results show that the majority of the dreamers reported dreams about their intact body although the mean time that elapsed since the amputation was twelve years. There is no clear relation with the type of amputation. The results give modest evidence for the existence of a basic neural representation of the body that is, at least, partly genetically determined and by this relatively insensitive for changes in the sensory input.     

Cognitive Behavioral Therapy Across the Stages of Psychosis: Prodromal, First Episode, and Chronic Schizophrenia

Since the early 1990s, cognitive behavioral therapy (CBT) has been increasingly used as an adjunctive treatment for psychotic disorders. This paper describes the CBT of three cases, each at a different stage of psychotic disorder: at-risk mental state, first-episode psychosis, and chronic psychotic disorder. For the at-risk mental state, treament focused on anxiety and social phobia, whereas the treatment of first-episode psychosis focused on the development of a shared formulation of the factors leading to and maintaining psychotic symptoms. For the chronic case, treatment emphasized the possibility of improving strategies to prevent symptoms from interfering with life goals. The potential contribution of CBT to improve outcomes in psychotic disorders beyond those obtained through traditional pharmacotherapy is discussed.     

Continuation of exchange with neighbors in later life: The importance of the neighborhood context

Relationships with neighbors are considered exchange relationships, in which the continuation of exchanges depends on balance in previous exchanges. Our study tested whether this is the case. An exchange relationship implies that neighbor relationships are isolated units. We expected, however, that neighborhood integration also affects the continuation of exchange among neighbors. Data were from a longitudinal study among 1,692 independently living Dutch adults of ages 55 to 85 years at baseline and their 7,415 relationships with proximate network members. At a four–year follow–up, both perceived balance and neighborhood integration at baseline increased the chance of instrumental support exchange occurring. We concluded that it is too limited to view relationships between neighbors as exchange relationships, as these relationships are embedded in larger communities, where such communities exist.     

Must All be Saved? A Kierkegaardian Response to Theological Universalism

In this paper, I consider how a Kierkegaardian could respond critically to the question of strong theological universalism, i.e., the belief that all individuals must eventually be reconciled to God and experience everlasting happiness. A Kierkegaardian would likely reject what Thomas Talbott has called “conservative theism,” but has the resources to mount a sustained attack on the view that all individuals must experience everlasting happiness. Some have seen that Kierkegaard has some potential in this regard, but a full Kierkegaardian response to strong theological universalism has yet to be given. In this paper, I give such an account. That God could create beings free over against himself is the cross which philosophy could not bear but upon which it has remained hanging. – Kierkegaard     

An Examination of the Actor-Observer Effect in Young Drivers' Attributions for Their Own and Their Friends' Risky Driving

The attributions of 70 young drivers for their own and their friends' risky driving were examined using open-ended questions to determine if there were self-other differences consistent with the actor-observer effect. Six response categories were created, 4 of which were rated as more dispositional than situational by a subsample of the participants and 2 of which were rated as more situational than dispositional. While the largely dispositional category "Showing off, acting cool" was used significantly more for friends than for self, and the largely situational "In a hurry, late" was used significantly more for self than for friends, there was only limited support for the actor-observer effect overall. The participants also rated their friends as taking more risks than themselves. The actor-observer differences are suggested to be influenced primarily by motivational factors and the context in which young people observe their friends' driving. New approaches to traffic safety interventions are suggested.
