Social security as a prerequisite for a socio‐technological design

The author of this article advances the view that socio‐political concepts are prerequisites for an adequate elaboration of a technological design which is ecologically and socially sound. Two approaches are of particular relevance: namely, that of vocational training and that of increased employee participation in the decision‐making procedures of enterprises and organizations.     

Aus Fehlern Iernen

Learning from blunders. Experiences of an executive coach with problems and solutionsNot too often, even rarely, we are in a situation to talk about blunders or shortcomings within our coaching community. That really is a pity, because a discussion like this combined with reflection and feed back is the best and only way for a coach to avoid professional mistakes in his future. So this article is “somehow another kind” of contribution. The author reports his own 18 years of “blunder-experience” as well as professional mistakes of other coaches which he observed in mentor coachings and supervisions, he suggests outcomes, consequences and solutions. Topics are: Anger, aggression and “struggles of power” within the coaching process; dependence versus (internal) independence of a coach; transference and counter-transference within the coaching process; peanut politics within a coaching process. Result: the coach himself, his core values, his boldness directed to social risks and to natural consequences — combined with appreciative conversation and respecting clients — makes out the core dissolving capacity. Without mentor coaching and professional supervision every coach would be trapped into his personal “trap of mistakes” — and even worse: without recognizing this dilemma.     

Experiments with cooperative 2 × 2 games

Nash's solution of a two-person cooperative game prescribes a coordinated mixed strategy solution involving Pareto-optimal outcomes of the game. Testing this normative solution experimentally presents problems in as much as rather detailed explanations must be given to the subjects of the meaning of threat strategy, strategy mixture, expected payoff, etc. To the extent that it is desired to test the solution using naive subjects, the problem arises of imparting to them a minimal level of understanding about the issue involved in the game without actually suggesting the solution.Experiments were performed to test the properties of the solution of a cooperative two-person game as these are embodied in three of Nash's four axioms: Symmetry, Pareto-optimality, and Invariance with respect to positive linear transformations. Of these, the last was definitely discorroborated, suggesting that interpersonal comparison of utilities plays an important part in the negotiations.Some evidence was also found for a conjecture generated by previous experiments, namely that an externally imposed threat (penalty for non-cooperation) tends to bring the players closer together than the threats generated by the subjects themselves in the process of negotiation.     

Extension of internationalisation models: drivers and processes for the globalisation of product development – a comparison of Danish and Chinese engineering firms

This paper develops an extension to established production- and supply chain management focused internationalisation models. It applies explorative case studies in Danish and Chinese engineering firms to discover how the globalisation process of product development differs from Danish and Chinese perspectives. The paper uses internationalisation and global product development theory to explain similarities and differences in the approaches. Grounded in case study results, a new model for internationalisation is proposed. The new model expands the internationalisation process model to include steps of product development and collaborative distributed development beyond sourcing, sales and production elements. The paper then provides propositions for how to further develop the suggested model, and how western companies can learn from the Chinese approaches, and globalise their product development activities from the front end of the value chain rather than from the back-end.     

Coordinating Service‐Sensitive Demand and Capacity by Adaptive Decision Making: An Application of Case‐Based Decision Theory*

The subject of this article is the simultaneous choice of product price and manufacturing capacity if demand is stochastic and service‐level sensitive. In this setting, capacity as well as price have an impact on demand because several aspects of service level depend on capacity. For example, delivery time will be reduced if capacity is increased given a constant demand rate. We illustrate the relationship between service level, capacity, and demand reaction by a stylized application problem from the after‐sales services industry. The reaction of customers to variations in service level and price is represented by a kinked price‐demand‐rate function. We first derive the optimal price‐capacity combination for the resulting decision problem under full information. Subsequently, we focus on a decision maker (DM) who lacks complete knowledge of the demand function. Hence the DM is unable to anticipate the service level and consequently cannot identify the optimal solution. However, the DM will acquire additional information during the sales process and use it in subsequent revisions of the price‐capacity decision. Thus, this decision making is adaptive and based on experience. In contrast to the literature, which assumes certain repetitive procedures somewhat ad hoc, we develop an adaptive decision process based on case‐based decision theory (CBDT) for the price‐capacity problem. Finally, we show that a CBDT DM in our setting eventually finds the optimal solution, if the DM sets the price based on absorption costs and adequately adjusts the capacity with respect to the observed demand.     

LEARNING WITH DETERMINISTIC DECISION RULES

While many problems of uncertainty are commonly analyzed by means of stochastic models, under certain circumstances this may not be an appropriate approach. The latter situation arises when the decision maker knows that the uncertain variables are not generated by a stochastic process, or when he is unwilling, or unable, to compute subjective probabilities. One of the nonstochastic approaches to uncertainty is the expectational approach in which the decision maker forms deterministic expectations about the uncertain aspects of his environment. This paper is concerned with some criteria for selecting among available expectations, or anticipations functions, and the possibility of ordering them according to these criteria. This study focuses especially on the learning criterion. The discussion brings out conceptual problems in connection with the definition of learning, as well as some technical difficulties that one encounters when attempting to compare different anticipations functions from the point of view of the learning criterion. As an illustration of the issues discussed, the paper reports on the results of some simulated decision rules. These show that decision rules in which no learning takes place, and in which some information is ignored, may perform better than more sophisticated rules.     

Frauencoaching, Gender-Coaching und nun auch noch Männercoaching oder „Ein Freund, ein guter Freund, das ist das Beste, was es gibt auf der Welt!“

Coaching of women, gender coaching and now finally coaching of men? The author describes and discusses the councelling of male managers based on the latest research project of men’s studies in Germany. He defines the emerging problems of male coping strategies in councelling, supervision and coaching. Finally he discusses the meaning of male councellers in relation to male coachees.     

Do immigrants displace young native workers: The Austrian experience

This paper studies the effect of increased immigration in Austria on the unemployment risk of young natives. Austria experienced a dramatic rise in the share of alien workers as a result of the breakdown of the former communist regimes (especially from former Yugoslavia). We concentrate on unemployment entry of young male workers, who are supposed to compete most heavily with new immigrants. Our results indicate that the detrimental impact – if it exists at all – is only minor. This is irrespective of the analyzed proxy for competition: The share of foreign workers in an industry or in a region. Received: 7 March 1996/Accepted: 20 March 1998
