Rules of Crowdsourcing: Models, Issues, and Systems of Control

Abstract: In this paper, we first provide a practical yet rigorous definition of crowdsourcing that incorporates “crowds,” outsourcing, and social web technologies. We then analyze 103 well-known crowdsourcing websites using content analysis methods and the hermeneutic reading principle. Based on our analysis, we develop a “taxonomic theory” of crowdsourcing by organizing the empirical variants in nine distinct forms of crowdsourcing models. We also discuss key issues and directions, concentrating on the notion of managerial control systems.

Cognitive Effects of Bilingualism: How Linguistic Experience Leads to Cognitive Change

Abstract: Bilinguals must have a mechanism for controlling attention to their two language systems in order to achieve fluent performance in each language without intrusions from the other. This paper examines the evidence that the experience of controlling attention to two languages boosts the development of executive control processes in childhood for bilinguals, sustains cognitive control advantages for bilinguals through adulthood and protects bilingual older adults from the decline of these processes with ageing. Future research with bilingualism should explore these effects in a broader and more multidisciplinary context in order to provide a more detailed understanding of the functioning of the bilingual mind.

The politics of care in technoscience.

Abstract: Care is a slippery word. Any attempt to define it will be exceeded by its multivocality in everyday and scholarly use. In its enactment, care is both necessary to the fabric of biological and social existence and notorious for the problems that it raises when it is defined, legislated, measured, and evaluated. What care looks and feels like is both context-specific and perspective-dependent. Yet, this elusiveness does not mean that it lacks importance. In our engagements with the worlds that we study, construct, and inhabit, we cannot but care: care is an essential part of being a researcher and a citizen. To properly invite you into this Special Issue, then, we need to say something about what we mean when we write about care.

Emotion in psychotherapy: a practice-friendly research review

Abstract: This article reviews the process and outcome research on emotion in psychotherapy. Four distinct types of emotion processes are identified in the literature as useful in therapy, depending on a client's presenting concerns: emotional awareness and arousal; emotional regulation, active reflection on emotion (meaning making), and emotional transformation. Research findings are summarized to highlight the practical implications of these different emotion processes to psychotherapy. A range of selected treatments from different therapeutic orientations are addressed collectively as different types of emotion-focused, experiential therapies and are compared on the basis of how they work with emotion in session.

A graph-theoretic approach to the method of global Lyapunov functions

Abstract: A class of global Lyapunov functions is revisited and used to resolve a long-standing open problem on the uniqueness and global stability of the endemic equilibrium of a class of multi-group models in mathematical epidemiology. We show how the group structure of the models, as manifested in the derivatives of the Lyapunov function, can be completely described using graph theory.
