Single Parents and Paid Work

Radical social changes in household formation over the past three decades have given rise to the single parent family. In spite of the level of public assistance, which is among the most generous in the OECD, research has shown that single parents (usually mothers) are among the most impoverished members of society. Recent legislation is moving toward mandating single parents off public assistance and into paid work in order for them to achieve more sustainable futures. In this paper we argue that this strategy is unlikely to succeed unless the particular needs of single parents are understood and addressed within a broader debate concerning women, care, and paid work. Family‐friendly workplace practices, more extensive publicly funded childcare, and better opportunities for lifelong learning are some of the changes that are urgently needed to assist not only single parents but all who try to combine the dual roles of working and caring.     

Knowledge attributes and the choice of knowledge transfer mechanism in networks: the case of franchising

In this paper we develop a knowledge-based view on the choice of knowledge transfer mechanisms in franchising that integrates results from the information richness theory. Starting from the information richness theory we argue that tacitness of system knowledge, operationalized by codifiability, teachability and complexity, determines the information richness of the knowledge transfer mechanisms of franchising firms. We examine the following hypotheses: (1) If the franchisor’s knowledge is characterized by a high degree of codifiability and teachability and a low degree of complexity, knowledge transfer mechanisms with a lower degree of information richness are used; (2) If the franchisor’s knowledge is characterized by a high degree of complexity and a low degree of codifiability and teachability, knowledge transfer mechanisms with a higher degree of information richness are used. We test these hypotheses by using data from 52 franchising firms in the Austrian franchise sector. The data provide support for the hypotheses.     

Structural and contextual approaches to ambidexterity: A meta-analysis of organizational and environmental contingencies

This meta-analysis examines the conditions under which structural and contextual approaches help balance exploration and exploitation. Drawing on heterogeneous samples of prior ambidexterity studies, we apply moderated meta-analytic regression methods to 33,492 organizations sampled in 114 primary studies from 1991 to 2017 to test a contingency model. Our findings suggest that structural separation helps firms of all sizes to balance exploration and exploitation, and that structural separation is more conducive for balancing exploration and exploitation in high technology environments. Also, avoiding a structural separation approach benefits service firms. As research on ambidexterity enters the maturity stage we discuss the implications for future theory development, methodology, and for managers interested in developing ambidextrous organizations.     

How Should Autonomous Cars Drive? A Preference for Defaults in Moral Judgments Under Risk and Uncertainty

Autonomous vehicles (AVs) promise to make traffic safer, but their societal integration poses ethical challenges. What behavior of AVs is morally acceptable in critical traffic situations when consequences are only probabilistically known (a situation of risk) or even unknown (a situation of uncertainty)?  How do people retrospectively evaluate the behavior of an AV in situations in which a road user has been harmed? We addressed these questions in two empirical studies (N = 1,638) that approximated the real‐world conditions under which AVs operate by varying the degree of risk and uncertainty of the situation. In Experiment 1, subjects learned that an AV had to decide between staying in the lane or swerving. Each action could lead to a collision with another road user, with some known or unknown likelihood. Subjects’ decision preferences and moral judgments varied considerably with specified probabilities under risk, yet less so under uncertainty. The results suggest that staying in the lane and performing an emergency stop is considered a reasonable default, even when this action does not minimize expected loss. Experiment 2 demonstrated that if an AV collided with another road user, subjects’ retrospective evaluations of the default action were also more robust against unwanted outcome and hindsight effects than the alternative swerve maneuver. The findings highlight the importance of investigating moral judgments under risk and uncertainty in order to develop policies that are societally acceptable even under critical conditions.     

Task design as an influence on dialogue and learning: primary school group work with object flotation

Previous studies suggest that group work would yield conceptual gains in physics if tasks specifically promoted dialogue about the factors which determine observed outcomes. This might be done by constraining task items to present critical tests of the effects of individual factors; and, additionally, by requiring participants to generate or select explicit rules about those effects. In order to test this hypothesis, groups of primary school children were asked to work on one of four versions of a task concerning object flotation: Random (i.e. a control in which there were no task constraints), Critical Tests, Rule Generation, and Rule Selection. Learning was assessed via change between a pre-test and two post-tests. Although the effect was delayed, children from the Random and Rule Generation conditions showed an increased awareness of relevant factors which was strongly related to prior group activity. This gain was absent in the Critical Tests and Rule Selection conditions. The results indicate that group dialogue can be productively shaped by task design, but also that its effects may take time to appear, and are negated by overmuch external direction of attention.
