Niklas Luhmann's Systems Theory as a Challenge for Ethics

The author discusses Niklas Luhmann's concept of ethics and morals. Therefore he sketches the main traits of Luhmann's theory of systems (e.g. the terms autopoiesis, system and environment, code and programme). From the system-theoretical point of view, ethics are characterized as the reflexive theory of morals. Morals are described as the communication of regard or disregard. The author shows which consequences follow from this concept by discussing problems concerning several subsystems at the same time. The problems of Luhmann's theory of morals and ethics are demonstrated by analyzing the concepts of risk and responsibility. Finally, the author demands that ethics should be understood even more as social ethics which reflect upon their social foundation in a more consequent way.     

Long-term stability of cognitive behavioral therapy effects for panic disorder with agoraphobia: A two-year follow-up study

Objective

Cognitive-behavioral therapy (CBT) aims to help patients establish new behaviors that will be maintained and adapted to the demands of new situations. The long-term outcomes are therefore crucial in testing the durability of CBT.

Method

A two-year follow-up assessment was undertaken on a subsample of n = 146 PD/AG patients from a multicenter randomized controlled trial. Treatment consisted of two variations of CBT: exposure in situ in the presence of the therapist (T+) or on their own following therapist preparation (T−).

Results

Both variations of CBT had high response rates and, overall, maintained the level of symptomatology observed at post-treatment with high levels of clinical significance. Effect sizes 24 months following treatment were somewhat lower than at the 6-month follow up. Once patients reached responder status, they generally tended to remain responders at subsequent assessments. Differences were observed for patients that obtained additional treatment during the follow-up period. Expert opinion and subjective appraisal of treatment outcome differed. No robust baseline predictors of 2-year outcome were observed.

Conclusion

Most patients maintain clinically meaningful changes two years following treatment across multiple outcome measures. Approximately 1/3 of patients continued to experience meaningful residual problems.     

Perception of men's personal qualities and prospect of employment as a function of facial hair

The present study investigated the contribution of men's facial hair to impression formation. Participants evaluated photographs of one of four versions of a man--clean shaven, mustached, goateed, or bearded--on a 7-point scale. In Study 1, participants were 106 Brazilian undergraduates (68 men and 38 women). Beardedness was associated with older age, greater responsibility, and leftist political ideas. In Study 2, respondents were 50 Brazilian personnel managers (28 men and 22 women) who made hiring decisions at different companies in the city of Sa? Paulo. Personnel managers clearly preferred clean shaven over bearded, mustached, or goateed men as prospective employees. In a hiring situation for a conservative occupation, a man who signals disposition to conform to rules may be preferred by personnel managers over another who signals nonconformity.     

Reflexive monism versus complementarism: An analysis and criticism of the conceptual groundwork of Max Velmans’s reflexive model of consciousness

From 1990 on, the London psychologist Max Velmans developed a novel approach to (phenomenal) consciousness according to which an experience of an object is phenomenologically identical to an object as experienced. On the face of it I agree; but unlike Velmans I argue that the latter should be understood as comparable, not to a Kantian, but rather to a noematic ‘phenomenon’ in the Husserlian sense. Consequently, I replace Velmans’s reflexive model with a complementaristic approach in a strict sense which leaves no room for either monistic or dualistic views (including Velmans’s ontological monism and his dual-aspect interpretation of complementarity) and hence requires us to radically reinterpret the concept of psychophysical causation.

Question answering from structured knowledge sources

We present an implemented approach for domain-restricted question answering from structured knowledge sources, based on robust semantic analysis in a hybrid NLP system architecture. We perform question interpretation and answer extraction in an architecture that builds on a lexical-conceptual structure for question interpretation, which is interfaced with domain-specific concepts and properties in a structured knowledge base. Question interpretation involves a limited amount of domain-specific inferences, and accounts for higher-level quantificational questions. Question interpretation and answer extraction are modular components that interact in clearly defined ways. We derive so-called proto queries from the linguistic representations, which provide partial constraints for answer extraction from the underlying knowledge sources. The search queries we construct from proto queries effectively compute minimal spanning trees from the underlying knowledge sources. Our approach naturally extends to multilingual question answering, and has been developed as a prototype system for two application domains: the domain of Nobel prize winners, and the domain of Language Technology, on the basis of the large ontology underlying the information portal LT World.
