How to reduce workload--augmented reality to ease the work of air traffic controllers

In the future the air traffic will rise--the workload of the controllers will do the same. In the BMWi research project, one of the tasks is, how to ensure safe air traffic, and a reasonable workload for the air traffic controllers. In this project it was the goal to find ways how to reduce the workload (and stress) for the controllers to allow safe air traffic, esp. at huge hub-airports by implementing augmented reality visualization and interaction.     

A first empirical investigation into the pleasure of control as explaining factor in usage durations of information systems

To predict the technology acceptance of a system before market release is one of the big challenges of today. Many models are concerned with the question if someone is going to accept the system or not. Within this work a first empirical investigation of a personal trait called Pleasure of Control (PoC) is presented. Pleasure of Control is a construct that divides people into those people enjoy having control over a technical system and those who do not. It is predicted that a high Pleasure of Control leads to a prolonged system usage and unwillingness to accept highly automated systems. This paper presents a first empirical investigation of Pleasure of Control with 10 Persons with focus on usage durations. An experimental study revealed differences in the usage durations of a technical system (Apple iPad) between users with high and user with low Pleasure of Control measures.     

Recent Research on the Psychological Effects of Unemployment

Economic turbulence in the early 1980s stimulated not only popular and governmental concern about the effects of unemployment, but also extensive research on the topic. This journal issue presents 10 representative reports of such recent research from the United States and Europe. Of the two principal methodologies used in this field, aggregate time-series analysis and individual-level surveys, this issue is limited to the individual-level literature. Two papers provide a social psychological and human developmental orientation to the topic. Then, six papers address the psychological costs of unemployment, four based on population surveys and two dealing with plant closings. Finally, two papers describe policy responses being considered or implemented in North America and Europe.     

Analyzing migration decisions: the first step-whose decisions?

Many theories of geographic mobility assume that the change-of-residence process includes a substantial degree of choice. This paper classifies stated reasons for moving from the 1973 through 1977 Annual Housing Survey into forced, imposed, and preference-dominated categories. About 25 percent of residential mobility and 40 percent of migration occurred under conditions of substantial constraint. Mobility was most often constrained by family dynamics; for migration, occupational relocations frequently imposed the decision-to-move process and determined destinations. The volume of constrained movement indicates that its impact upon individuals, population dynamics, and voluntaristic theories of mobility deserves greater consideration.     

Karen Horney (1885–1952) A Tribute

It is twenty-five years since the passing of Karen Horney. A productive professional who dared to differ with Sigmund Freud, Horney has written clearly and brilliantly, almost in a "common-sensical" style, about the development of neurotic character structure and interpersonal relationships. Her stress on cultural, societal, and family influences has strong implications for theorists and professional practitioners in the field of marriage and the family. Her optimistic view of human nature, especially as it relates to the possibility for change at all ages and stages, should be a continuous inspiration to those helping disturbed individuals, relationships, marriages, and families. This is a tribute to a rare, worthy human being.     

An application of multiple objective linear programming to media selection

A multiple objective linear programming (MOLP) method utilizing interval criterion weights is applied to the problem of media selection. Using this technique, it is possible to analyze a problem more explicitly in terms of the several objectives inherent in many media selection situations. In order to illustrate the interval criterion weights approach, a multiple objective hierarchical media selection model is presented and its computer results discussed. In addition to being able to deal more directly with different decision criteria, a distinguishing feature of the mathematical analysis applied here is that its output enables the media-planner to be presented with a small cluster of candidate media schedules (rather than just one). Then, from this list, the media-planner should be in a position to qualitatively make a final choice as a close approximation to his optimal solution.     

Business drivers not sector membership determine the most effective production planning and control; a novel approach to a perennial problem

This paper outlines research aimed at developing novel planning and scheduling reference models for industrial sectors where the MRPII paradigm is not appropriate. It outlines the process mapping approach adopted, the data capture method developed for the case study companies, the use of ARIS (Scheer's) enterprise modelling tool, and the first stages in the production of sector reference models.
