How Is Critical Ontology Possible? Toward the Foundation of the General Theory of the Categories, Part One (1923)

This is a translation of an early essay by the German philosopher Nicolai Hartmann (1882–1950). In this 1923 essay Hartmann presents many of the fundamental ideas of his new critical ontology. He summarizes some of the main points of his critique of neo-Kantian epistemology, and provides the point of departure for his new approach in an extensive criticism of the errors of the classical ontological tradition. Some of these errors concern the definition of an ontological category or principle, and others concern the relations among categories themselves. The outline for the new ontology is sketched through the correctives Hartmann appends to the treatment of each error, prefiguring his mature ontological system.     

A Return to “The Clinic” for Community Psychology: Lessons from a Clinical Ethnography in Urban American Indian Behavioral Health

Community psychology (CP) abandoned the clinic and disengaged from movements for community mental health (CMH) to escape clinical convention and pursue growing aspirations as an independent field of context‐oriented, community‐engaged, and values‐driven research and action. In doing so, however, CP positioned itself on the sidelines of influential contemporary movements that promote potentially harmful, reductionist biomedical narratives in mental health. We advocate for a return to the clinic—the seat of institutional power in mental health—using critical clinic‐based inquiry to open sites for clinical‐community dialogue that can instigate transformative change locally and nationally. To inform such works within the collaborative and emancipatory traditions of CP, we detail a recently completed clinical ethnography and offer “lessons learned” regarding challenges likely to re‐emerge in similar efforts. Conducted with an urban American Indian community behavioral health clinic, this ethnography examined how culture and culture concepts (e.g., cultural competence) shaped clinical practice with socio‐political implications for American Indian peoples and the pursuit of transformative change in CMH. Lessons learned identify exceptional clinicians versed in ecological thinking and contextualist discourses of human suffering as ideal partners for this work; encourage intense contextualization and constraining critique to areas of mutual interest; and support relational approaches to clinic collaborations.     

Neurochemical knowledge in electroconvulsive therapy (ECT)

The paper is concerned with an attempt to generalize and categorize current hypotheses on the biochemical basis of ECT. The hypotheses are critically evaluated with respect to the relevance of their experimental fundamentals. Thus, certain hypotheses are valid only in a qualified sense. Particular interest is focussed on those conceptions which try to correlate ECT-induced changes in synaptic receptor sensitivities (up-/down-regulation) with super- resp. subsensitivity hypotheses of psychoses. In this connection, noradrenergic and opioid systems on the one hand, and the axis hypothalamus-hypophysis on the other hand seem to play a dominant role.     

Generalized Quantum Theory: Overview and Latest Developments

The main formal structures of generalized quantum theory are summarized. Recent progress has sharpened some of the concepts, in particular the notion of an observable, the action of an observable on states (putting more emphasis on the role of proposition observables), and the concept of generalized entanglement. Furthermore, the active role of the observer in the structure of observables and the partitioning of systems is emphasized.     

Regulatory focus and investment decisions in small groups

Regulatory Focus Theory was applied to small interactive groups. Based on previous research, it was expected that groups with a promotion focus would discuss gain-relevant information, whereas groups with a prevention focus would be concerned with potential losses. Furthermore, promotion groups were expected to make riskier decisions than prevention groups. Regulatory focus was manipulated by rewarding good or penalizing poor group performance on a preliminary task. Subsequently, three-person groups discussed several investment funds and made a consensual investment decision. Results supported the hypotheses and suggested that regulatory focus requires time to exert its influence in groups.     

A Unified Nonparametric IRT Model for <Emphasis Type="Italic">d</Emphasis>-Dimensional Psychological Test Data (<Emphasis Type="Italic">d</Emphasis>-ISOP)

The (univariate) isotonic psychometric (ISOP) model (Scheiblechner, 1995) is a nonparametric IRT model for dichotomous and polytomous (rating scale) psychological test data. A weak subject independence axiom W1 postulates that the subjects are ordered in the same way except for ties (i.e., similarly or isotonically) by all items of a psychological test. A weak item independence axiom W2 postulates that the order of the items is similar for all subjects. Local independence (LI or W3) is assumed in all models. With these axioms, sample-free unidimensional ordinal measurements of items and subjects become feasible. A cancellation axiom (Co) gives, as a result, the additive isotonic psychometric (ADISOP) model and interval scales for subjects and items, and an independence axiom (W4) gives the completely additive isotonic psychometric (CADISOP) model with an interval scale for the response variable (Scheiblechner, 1999). The d-ISOP, d-ADISOP, and d-CADISOP models are generalizations to d-dimensional dependent variables (e.g., speed and accuracy of response). The author would like to thank an Associate Editor and two anonymous referees and also Professor H.H. Schulze for their very valuable suggestions and corrections.     

The rhythm of melatonin synthesis in the epiphysis and its control by light

The paper deals with the central regulation of the circadian rhythm of the melatonin in the pineal gland by light according to the literature. Examples of the effects of melatonin and their inclusion in the total endocrine complexity are pointed out. Possibilities for a therapy of chronobiological diseases with bright light resulting from animal experiments are discussed in connection with requirements for a future application to the therapy of human beings.     

A cautionary note on the use of probability values to evaluate interobserver agreement

Proposed methods of assessing the statistical significance of interobserver agreements provide erroneous probability values when conducted on serially correlated data. Investigators who wish to evaluate interobserver agreements by means of statistical significance can do so by limiting the analysis to every k(th) interval of data, or by using Markovian techniques which accommodate serial correlations.
