The News Media in Children's Political Socialization

The research reported examines the impact of the news mediaas an agent of political socialization on children's politicalknowledge, their attitudes toward political parties and electoralsystems, and their activities relative to politics. Childrennews media use and level of political knowledge function asprimary sources of causal effects for each other. They are consistentlymore important in their effects on the attitudes and types ofparticipation studied in this research than are the parentaland educational system socialization indicators or the structuralvariables of grade and gender.     

Moving through Time and Space: Performing Bodies in Derry, Northern Ireland

Abstract  This paper examines the embodied remembrance of Bloody Sunday (1972), when thirteen civilians were shot dead by British soldiers while peacefully marching against internment. The work of Paul Connerton represents a crucial analytical starting point in a growing number of studies examining the body as site of memory. While Connnerton's theorisation has been very influential and persuasive, I argue that there is some scope for improving his ideas about the changeability of bodily memory and the Bloody Sunday case represents an interesting empirical example of how embodied remembrance reflects and responds to transformations in the wider socio-political context.     

Dual citizenship or dual identity? Does ‘transnationalism’ supplant ‘nationalism’ among returning Trinidadians?

In this article we focus on the dual identities of relatively young Trinidadians who have decided to return to the island of their birth, or of their parents, while still in their thirties and forties. Highly‐educated professional transnational migrants mostly make up our sample of 36; 26 possess dual citizenship. We focus on our informants’ narratives about their transnational experiences, self‐appraisals of their dual identities and how they value dual citizenship. More generally, we ask, does transnationalism supplant nationalism among our returning informants? Unsurprisingly, the diverse responses we document do not support the commonly held explanatory relationship between return adaptations, ‘national belonging’ and the expected dominance of ‘transnational belonging’. Family relations intervene significantly, both to encourage transnationalism and to strengthen nationalism. Feelings of national belonging often accompany transnationalism. Notably, we view dual citizenship strategically and pragmatically as advantageous to the continuation of transnational practices.     

MANAGING CYCLIC INVENTORIES

Cyclic inventory is the buffer following a machine that cycles over a set of products, each of which is subsequently consumed in a continuous manner. Scheduling such a machine is interesting when the changeover times from one product to another are non‐trivial—which is generally the case. This problem has a substantial literature, but the common practices of “lot‐splitting” and “maximization of utilization” suggest that many practitioners still do not fully understand the principles of cyclic inventory. This paper is a tutorial that demonstrates those principles. We show that cyclic inventory is directly proportional to cycle length, which in turn is directly proportional to total changeover time, and inversely proportional to machine utilization. We demonstrate the virtue of “maximum changeover policies” in minimizing cyclic inventory—and the difficulty in making the transition to an increased level of demand. In so doing, we explicate the different roles of cyclic inventory, transitional inventory, and safety stock. We demonstrate the interdependence of the products in the cycle—the lot‐size for one product cannot be set independently of the remaining products. We also give necessary conditions for consideration of improper schedules (i.e., where a product can appear more than once in the cycle), and demonstrate that both lot‐splitting and maximization of utilization are devastatingly counter‐productive when changeover time is non‐trivial.
