Ist die Katharsis-Theorie zu retten?

Catharsis theory is regarded as refuted. This widespread belief can be questioned for two reasons. First, most test films used in experimental studies do not meet the requirements of catharsis theory; second the social consequences of catharsis were not measured. Two films were produced for our experiment, one which meets the requirements of catharsis theory and should reduce aggressiveness and one which, according to alternative theories, should increase aggressiveness. A control group saw a neutral film. As dependent variables (a) level of general aggression, (b) aggressive inclinations in social situations, and (c) willingness to use aggressive stereotypes were measured. The film that was assumed to reduce aggressiveness increased aggressiveness even more than the film that was assumed to increase it. This surprising finding and its consequences are discussed.     

Obsoleszenz — ein Synonym für die Konsumgüterproduktion in entfalteten Marktwirtschaften

Zusammenfassung Wie im Titel angedeutet, gehen die Verfasser davon aus, daß sich hinter dem Obsoleszenz-Phänomen keine besondere Absatzstrategie der Unternehmen und daher kein eigenständiges Erkenntnisobjekt verbirgt. Die von bürgerlichen und marxistischen Kritikern vielfach geäßerte Ansicht, mit zunehmender Vermachtung/Monopolisierung der Märkte seien die Waren schlechter geworden, wird nicht geteilt. Nach wie vor werden bei uns sehr viele «gute» sowie «schlechte» Konsumgüter hergestellt, je nach dem wie die Produktivkräfte sowie die Konkurrenz um die zahlungskräftige Nachfrage es erlauben. Was die bekannten gesamtgesellschaftlichen Probleme (Umweltbelastung, Rohstoffknappheit etc.) verursacht und die Wissenschaften auf dem Plan gerufen hat, ist nicht die abnehmende Qualität der Waren, sondern die erweiterte Reproduktion kapitalistischen Wirtschaftens schlechthin. Die «ungeheure Warenansammlung» kann wissenschaftlich nicht zerlegt werden in eine unanfechtbare Normalität (=technischer Fortschritt) und moralisch abzulehnende Auswüchse (=Obsoleszenz); ebensowenig signalisieren Obsoleszenzstrategien die allgemeine Dekadenz des Monopolkapitals. Der Reichtum an Konsumgütern ist vielmehr zu begreifen als dialektisches Resultat einer Erwerbsgesellschaft, die-beispielhaft konkretisiert-überdimensionierte Fernsehgeräte zum Kauf anbietet, nachdem sie zuvor technisch ausgereifte Geräte entwickelt hat.

As indicated by the title the authors are convinced that obsolescence is no special marketing strategy. Therefore the phenomenon should not be regarded as a subject worthy of study by itself. The authors reject the hypothesis that product quality is eroded by increasing monopolization, a position taken by bourgeois as well as marxian critics. In market economies there will always be production of good and bad consumer goods depending on productive capacity and sellers' competition for effective demand. The well-known social problems (pollution, shortage of raw materials, etc.) are not caused by decreasing product quality but are due to the need for reproduction of capital on a larger scale.The enormous production of goods cannot be separated by scientific methods into (a) an economic normality (technical progress) and (b) a perverse exaggeration not acceptable on moral grounds (obsolescence). Neither do the strategies of obsolescence indicate the decadence of monopolistic capitalism. Instead the abundance of consumer goods should be interpreted as a dialectic result of a society's profit maximization. To give an example: After well-equipped television sets with a high technical standard had been developed, the system starts supplying units of a hypertrophic size and capacity.

     

A REVISED GEOMETRY OF MEAN-VARIANCE EFFICIENT PORTFOLIOS

A revised definition of efficiency compares portfolios with different net worths. One axiom rules out instantaneous riskless gains, the other asserts that it costs money to buy good portfolios. Unlimited short sales are allowed. Portfolios which cannot be improved at any price are called absolutely efficient. The geometry of the mean-standard deviation frontiers is governed by three “efficient set constants”. A few results regarding efficient portfolios must be modified, and a new version of the security line equation is proposed. Explicit formulas are given: no need to use different formulas for singular or non-singular covariance matrix.     

Experience with a simulator for training ammonia plant operators

A computer-based simulator was used for training operators prior to the start-up of a new fertilizer complex which includes a 1,350-MTPD ammonia plant, two 1,100-MTPD urea plants, and a steam and power generation plant with two 18-MW gas turbines. The simulator offered many benefits, which can be used for continued education of operators and engineering studies.     

The relationship between legitimacy,reputation, sustainability and branding for companies and their supply chains

This paper aims at filling a gap that we perceive to exist in the scientific literature as to legitimacy, reputation and sustainability and their interrelationship to corporate and supply chain branding. A series of innovative theoretical frameworks are provided interrelating companies and their value (supply) chains with legitimacy, reputation, and branding which are essential conditions to achieve sustainability and competitive advantage based on dyadic and social context consonance to the benefit of society and all stakeholders involved. An urgently required better understanding of the concepts and their interrelations is enhanced by a synthesized explanatory basis entailing an eclectic mosaic of interdisciplinary theories (institutionalist, neo-institutionalist theories, the viable system approach, isomorphism and identity) to improve corporate and supply chain performance. To better inform managerial practice the theoretical considerations are spiced with case studies among which especially the currently debated supply chain case of the European horse meat scandal is illuminated suggesting concrete managerial cross-functional implications in the food industry. The paper culminates in the call for a newly to-be-established marketing stream we call ‘Sustainable and Curative Marketing’.     

Antecedents to Decision‐Making Quality and Agility in Innovation Portfolio Management

Innovation portfolio management (IPM) is a dynamic decision‐making process, in which projects are evaluated and selected, and resources are allocated. Previous research has developed an understanding of IPM success and its influencing factors. However, little research investigated the quality of the decision‐making process and the ability to quickly adapt the portfolio. This study focuses on the antecedents of decision‐making quality and agility (i.e., responsiveness to changes in the environment). Based on a decision‐making framework, five structural and cultural IPM components are derived as important antecedents of decision‐making quality, which in turn influences agility. The structural components (1) clarity of strategic goals, (2) formality of the IPM processes, and (3) controlling intensity serve a coordinating function. The cultural components (4) innovation climate and (5) risk climate serve a motivating function in IPM. An analysis of a sample of 179 firms and their innovation portfolios through structural equation modeling using a double‐informant design documents that these five components all positively influence portfolio decision‐making quality, which in turn positively influences agility. Results further show that environmental turbulence moderates some of these relationships. While the positive effect of process formality is weakened under increasing turbulence, the effects of controlling intensity and climate for innovation are strengthened by environmental turbulence. The findings have theoretical implications for the understanding of IPM as a dynamic capability and practical implications for the management of portfolios in turbulent environments.
