Quaternary dichotomous voting rules

In this article, we provide a general model of “quaternary” dichotomous voting rules (QVRs), namely, voting rules for making collective dichotomous decisions (to accept or reject a proposal), based on vote profiles in which four options are available to each voter: voting (“yes”, “no”, or “abstaining”) or staying home and not turning out. The model covers most of actual real-world dichotomus rules, where quorums are often required, and some of the extensions considered in the literature. In particular, we address and solve the question of the representability of QVRs by means of weighted rules and extend the notion of “dimension” of a rule.     

Purchasing performance management systems: an empirical investigation

This article aims at further developing the purchasing performance management systems (PPMSs) body of knowledge, assuming the wider perspective of the adoption process rather than key performance indicators (KPIs) only. In particular, the research questions are focused on understanding what are the most adopted indicators, what are the key elements characterising the implementation process and what are the differences among different organisational levels and different purchasing categories. The literature provides a framework for classifying purchasing KPIs, identifying the implementation process and the PPMS architecture, thus supporting the empirical research protocol. Nine case studies of large multinationals belonging to different industries are conducted. Empirical evidence shows that companies are still adopting mainly an external perspective, by focusing on performance measurement efforts on suppliers. Widely adopted indicators mainly measure cost, time and quality. However, the purchasing department has acquired an important role within the organisation and new performance indicators have been created; flexibility, innovation and sustainability are becoming increasingly important.     

Alternative uses of temporary work and new forms of work organisation

The purpose of this study is to investigate the relationship between the use of temporary workers and the adoption of new forms of work organisation (NFWO) in production. This study aims to understand to what extent these two forms of human resources flexibility are synergic or mutually exclusive. In order to answer this main goal, we discuss different levels of temporary workers adoption in relation to different levels of use of NFWO, the level of integration of temporary workers within the overall production organisation and the joint and synergistic use of NFWO and temporary work. Evidence drawn from seven case studies in manufacturing plants in northern Italy is provided. Results highlight that, according to the characteristics of the production process, temporary workers and NFWO are not mutually exclusive, that temporary workers can be integrated with other workers in the shop floor, and that NFWO can also be adopted for temporary workers. In addition, NFWO has been proven to be a key enabler to integrate temporary workers within the organisation, thus showing an important synergistic effect between the two human resource flexibility practices.     

Collective consumption: an application to the passive drinking effect

This study introduces a new collective complete demand system with individual Engel effects that is easy to estimate and permits undertaking policy analysis at the individual rather than household level. Previous estimations of collective demand were limited to single equations. The empirical application investigates the passive drinking effect, that is, whether consumption of alcohol affects the distribution of resources among household members and their level of wellbeing. The results show that a high level of alcohol consumption of one household member significantly affects the allocation of household resources and suggest thought-provoking policy implications.     

Savage in the Market

We develop a behavioral axiomatic characterization of subjective expected utility (SEU) under risk aversion. Given is an individual agent's behavior in the market: assume a finite collection of asset purchases with corresponding prices. We show that such behavior satisfies a “revealed preference axiom” if and only if there exists a SEU model (a subjective probability over states and a concave utility function over money) that accounts for the given asset purchases.     

Becoming a Culturally Responsive Special Educator Amidst School/University Partnerships: Teaching and Learning in Boundary-Zone Activity

This study presents an activity theory analysis of how special educators learn about culturally responsive practices amidst school–university partnerships. Particular attention was paid to how culturally responsive pedagogy was privileged and appropriated by an in-service and a pre-service teacher in a boundary-zone activity. Findings demonstrate how culturally responsive pedagogy was appropriated in light of previous pedagogical artifacts that preexisted in the activity system of the classroom and as a result it became a covert form of instructionism     

Building Factories Without Bosses: The Movement of Worker-Managed Factories in Argentina

In the 1990s and 2000s, Argentina suffered one of the quickest and most extreme processes of neoliberal state reforms in the world, leading to the closure of numerous factories. To resist the increased unemployment produced by neoliberalism, workers started to organize in a movement aimed at defending their only source of income: their labor. In this article, I analyze the main characteristics of the movement of worker-managed factories in Argentina by exploring how factories were occupied, what motivated the workers' decision to create co-operatives, what made the factories economically viable, how they were legitimated by the community, which legal reforms workers achieved to support their struggle, and how they manage their factories.
