Additive manufacturing technology adoption: an empirical analysis of general and supply chain-related determinants

Despite experiencing immense growth in the past decade, additive manufacturing (AM) technologies—colloquially known as 3D-printing—are still rarely used in industrial fabrication. Being at the interface between technology, innovation, behavioral science and operations management research, this paper identifies multifaceted factors that determine the decision to adopt AM technologies for the production of industrial parts. A review of the relevant literature revealed eight potential factors. These can be classified into four interdisciplinary categories: technology-related factors, firm-related-factors, market structure-related factors, and supply chain-related factors. Special focus is placed on the impact of supply chain-related issues, because there are indicatives that these aspects have an influence on the decision to adopt AM technologies since AM may offer distinct opportunities for both, the supply- and demand-side of a firm’s operations. No work in the field of manufacturing technology adoption has examined the role of such inter-organizational factors before. The results of an empirical study among 195 firms indicate that demand-side benefits and compatibility are the main determinants of AM technology adoption. This suggests that not only intra- but also inter-organizational factors should be considered when investigating the adoption of technological innovations. Furthermore, it is carved out that the adoption of AM technologies has an interdisciplinary nature.     

Learning from parents: A qualitative interview study on how parents experience their journey through the Dutch child protection system

The quality of parents' experiences with the child protection system (CPS) is related to the outcomes of their family's process in the system. The importance of collaboration with parents in child protection is underpinned by human and children's rights conventions addressing the right for family life and parents being first responsible in fulfilling children's rights. We interviewed 20 parents about their experiences with the Dutch CPS. Our thematic analysis shows that a CPS serving the best interests of their children is most important to parents. To realize this, professionals should (1) “not let it happen but do something,” (2) “get a clear picture of the family's situation,” and (3) “take parents seriously.” Parents emphasize that a system providing sufficient “money, time, and knowledge” is needed to facilitate professionals. Their experiences seem to influence their trust in the system and their attitude towards it. This study shows new insights in parents' experiences, such as their advice to professionals to determine the truth and to be decisive. This deepened knowledge about parents' experiences is essential for evaluating and improving the CPS.     

Equality preference in the claims problem: a questionnaire study of cuts in earnings and pensions

Many distributional conflicts are characterized by the presence of acquired rights. The basic structure of these conflicts is that of the so-called claims problem, in which an amount of money has to be divided among individuals with differing claims and the total amount available falls short of the sum of the claims. We describe the results of a questionnaire in which Belgian and German students were confronted with nine claims problems. In the “Firm” version, respondents had to divide revenue among the owners of a firm who contribute to the activities of the firm in different degrees. In the “Pensions” version, they had to divide tax money among pensioners who have paid different contributions during their active career. Responses in the Pensions version are more egalitarian than in the Firm version. For both versions, the proportional rule performs very well in describing the choices of the respondents. Other prominent rules—in particular the constrained equal awards and constrained equal losses rules—fail to capture some basic intuitions. A substantial part of the respondents tend to become more progressive as the amount to be distributed decreases other things equal, and tend to become more progressive as the inequality in the distribution of claims becomes more unequal other things equal. All of these conclusions are robust with respect to the difference in home-country of the respondents.     

A process evaluation of individual and organizational occupational stress and health interventions

There is reason to believe that many health and stress interventions fail due to inattention to the effects of intervention implementation processes, but evaluations of these processes are found only rarely in the literature. The objective of the present study was to explore the issue of obstacles to implementation that may occur when stress and health interventions are introduced in work organizations. The study was conducted as a process evaluation of seven different individual and organizational interventions. Interviews were conducted in 22 post offices, 12 organizational units (such as care homes and local administrative units) of a Norwegian municipality, and in 10 shops in a shopping mall. The interviews took place before and after the interventions. The following key process factors were identified: (1) the ability to learn from failure and to motivate participants; (2) multi-level participation and negotiation, and differences in organizational perception; (3) insight into tacit and informal organizational behaviour; (4) clarification of roles and responsibilities, especially the role of middle management; and (5) competing projects and reorganization. For improved studies of interventions in the future we recommend that qualitative and quantitative methods be combined, that researchers build more on natural interventions that occur naturally within the organization, and that a pilot study be undertaken in order to investigate the cultural maturity of the organization.     

Mutual Raiding of Production and the Emergence of Exchange

Joint exchange and raiding can emerge in a world of mutual raiding when the appropriated production is less valuable to the appropriator than to the defender and the defense is not too inferior to attack. The amounts of resources allocated to production and raiding and the amounts of goods exchanged reciprocally are determined endogenously. The model reduces to pure exchange and pure raiding as special cases. Pure exchange emerges when the usability of appropriation is sufficiently low. Pure raiding emerges if the defense is sufficiently inferior to attack. The results of the model are intermediate between the results of the two extreme cases.     

Defense Industry Restructuring: Trends in European and U.S. Defense Companies

The national defense industries have recognized that world circumstances have changed and consequently some radical changes are also required in their own structures. Increased concentration of defense production indicates that the central defense-industrial policy dilemma between the benefits of economies of scale and the benefits of competition has gradually been resolved in favor of scale economies. This article analyses the restructuring underway from a political-business perspective. It compares the different forms of corporate linkage ranging from full merger and takeover via less dramatic ties associated with strategic alliances and minority shareholdings to joint ventures. In particular, it explores these approaches from the perspective of their suitability to restructuring in the politically sensitive defense industry when the process spans national boundaries. The structure of the analysis involves an assessment of the progress of the U.S. defense industry and identification of the drives for change and the underlying dynamics of this industry. This gives a platform for a parallel analysis of pressures and changes among the European defense industry, leading to an analysis of how U.S. and European companies are placed regarding the industrial trends towards globalization.     

Sense of coherence: definition and explanation

The present study is one of a few that have used 'sense of coherence' (SOC) as a dependent variable in an explanatory model. After studying three different samples – 680 students, 180 parents and 315 couples – we conclude that family relational and psychopathological variables contribute significantly to the explanation of SOC (explained variance between 10–27 and 26–50 per cent). In total, we obtained an explained variance of between 42 and 64 per cent. This leads us to the conclusion that in all three samples, SOC is multifaceted and thereby is more than simply an opposite state to depression. Context may play an important part in the explanation of SOC.     

The glass ceiling – where is it? Women's and men's career prospects in the private vs. the public sector in Sweden 1979–2000

Previous research suggests that women have more limited career opportunities than men. Using Swedish longitudinal data, covering the period between 1979 and 2000, more light is shed on the association between hierarchical levels and differences between men's and women's career opportunities in terms of occupational transitions. The analyses indicate that women face the greatest hinderance to advancement at lower hierarchical levels and that these disadvantages attenuate with higher hierarchical levels. These results contradict the common idea of a glass ceiling, ie that problems for women accrue with increasing hierarchical levels. The findings point to the need for focusing more on gender inequalities at low hierarchical positions although the glass ceiling hypothesis cannot be dismissed altogether. Moreover, the results do not support the view that the gender penalty in careers is larger in the private sector as compared to the public sector.
