Structures,dynamics and mechanisms in neuroscience: an integrative account

Proponents of mechanistic explanations have recently proclaimed that all explanations in the neurosciences appeal to mechanisms. The purpose of the paper is to critically assess this statement and to develop an integrative account that connects a large range of both mechanistic and dynamical explanations. I develop and defend four theses about the relationship between dynamical and mechanistic explanations: that dynamical explanations are structurally grounded, that they are multiply realizable, possess realizing mechanisms and provide a powerful top-down heuristic. Four examples shall support my points: the harmonic oscillator, the Haken–Kelso–Bunz model of bimanual coordination, the Watt governor and the Gierer–Meinhardt model of biological pattern formation. I also develop the picture of “horizontal” and “vertical” directions of explanations to illustrate the different perspectives of the dynamical and mechanistic approach as well as their potential integration by means of intersection points.     

Deductive Reasoning in the Structuralist Approach

The distinction between the syntactic and the semantic approach to scientific theories emerged in formal philosophy of science. The semantic approach is commonly considered more advanced and more successful than the syntactic one, but the transition from the one approach to the other was not brought about without any loss. In essence, it is the formal analysis of atomic propositions and the analysis of deductive reasoning that dropped out of consideration in at least some of the elaborated versions of the semantic approach. In structuralist theory of science, as founded by Sneed and Stegmüller, the focus is on global propositions concerning the question of whether or not certain empirical systems satisfy a set-theoretic predicate that encodes the axioms of a scientific theory. Hence, an analysis of deductive reasoning from atomic premisses with the help of a given theory is missing. The objective of the present paper is to develop a deductive system on the basis of the structuralist framework. This system comes with a novel formulation of empirical propositions in structuralism.     

Apostolos in the new testament

This article examines the intersection between the therapeutic and the Christian cultures, and the common conviction among scholars of the therapeutic, such as Philip Rieff, that the subjective turn eventually will overthrow organized Christianity. The culture clash between secularism and religion is engaged through the Protestant Church of Norway's liturgical reform of the Sunday high mass 2004–2011, which aims to make the liturgical service more relevant. The analysis of both institutional and theological attempts at finding a balance between the old and the new suggests that the authority of the emotive self strongly challenges the truth of God. Still, there are signs of a cultural merger that suggest the Church of Norway will prevail. The outcome, however, will not satisfy conservative theologians and critics of the therapeutic culture, as God, in order to survive, must accept a more subordinate supportive role as an optional remedy for well-being.     

Objective work–nonwork conflict: From incompatible demands to decreased work role performance

Research on work–nonwork conflict (WNC) is based on the assumption that incompatible demands from the work and the nonwork domain hamper role performance. This assumption implies that role demands from both domains interact in predicting role performance, but research has been largely limited to main effects. In this multi-source study, we analyze the incompatibility of demands by testing the interaction of work and nonwork demands on task performance and organizational citizenship behavior (OCB). The sample consisted of 61 employees of a German hospital and we used three independent sources of data: self-ratings of work demands, partner-ratings of nonwork demands, and colleague-ratings of performance. Results from hierarchical regression analyses revealed an interaction effect of work and nonwork demands on OCB, but not on task performance. We conclude that people maintain their effort invested in task-related aspects of the job even when conflicts between work and nonwork demands exist, but that they reduce their investment in activities that are perceived as more marginal and extra-role.     

Satisfying one's needs for competence and relatedness: consequent domain-specific well-being depends on strength of implicit motives

Considering the effect of implicit motives, the current study examined the link between well-being in important life domains, that is, job and relationship, and the satisfaction of needs as proposed by self-determination theory. Data on domain-specific well-being, satisfaction of needs for competence and relatedness, and the implicit achievement and affiliation motives were assessed from 259 German and Cameroonian participants. The achievement motive moderated the relation between competence and job satisfaction. Furthermore, the affiliation motive moderated the association between relatedness and relationship satisfaction. Satisfaction of the needs for competence and relatedness is linked to higher levels of job and relationship satisfaction, respectively, among individuals with strong implicit motives. Effects were found regardless of participants' culture of origin. Findings indicate that implicit motives can be understood as weighting dispositions that affect how far experiences of competence and relatedness are linked with satisfaction in relevant life domains.     

Longer term outcome of cognitive-behavioural and psychodynamic psychotherapy in routine mental health care: randomised controlled trial

We investigated the comparative effectiveness of cognitive-behavioural (CBT) and psychodynamic therapy (PDT) under clinically representative conditions as a subtrial of a prior study (Watzke et al., 2010, BJP). A consecutive sample of 147 patients with common mental disorders was randomised to either CBT or PDT in routine mental health care. In a primary per-protocol analysis patients randomised to CBT had a significantly better longer term outcome in the primary outcome symptom severity (General Severity Index of the SCL-14; p=.001; partial η(2)=0.073) as well as in health related quality of life (Mental Component Summary of the SF-8; p=.013; partial η(2)=.041) and concerning interpersonal issues (Inventory of Interpersonal Problems, IIP-C; p=.001; partial η(2)=.070) 6 months after treatment than patients randomised to PDT. These results could be confirmed in intention-to-treat analyses (n=180) suggesting that there was no substantial attrition bias due to drop outs at the follow-up assessment. Thus, the so called equivalence outcome paradox was not replicated in this study.     

Johann Christian August Heinroth (1773–1843): The First Professor of Psychiatry as a Psychotherapist

Heinroth is known as the first professor of psychiatry. His chair was established 200?years ago on the 21st of October 1811. His major importance for the history of psychotherapy has not yet been acknowledged. Heinroth regarded restriction as well as activation as fundamental remedies for mental illnesses. Restriction meant making a voluntary decision to live a life based on religious faith and to abstain from earthly satisfaction. Within his specific psychotherapeutical module??the ??direct-psychic?? method??he utilized the patient??s mental powers??mood, mind and will, but also his spirituality. His therapeutic approach additionally contained elements of cognitive, behavioral and conversational therapy.
