SOR models and Ethnicity data in LIS and LES : country by country report

This research considers the idea that a single metric expressing distance between social groups may be an adequate tool for investigating the relationship between ethnic/nationality minority group membership and social stratification. A Stereotyped Ordered Regression (SOR) model is proposed as a methodology for deriving this metric 1, and this paper considers the role of SOR models for the variety of countries with appropriate data made available by the Luxembourg Income and Employment studies (LIS and LES). In particular, by making the referents of this metric relatively consistent between different countries, it is suggested that a cross-nationally comparable representation of ethnic/nationality group membership can be derived which reduces the difficulties of international comparative research on ethnicity. Section one of this paper deals with three introductory issues: the clarification of the proposed methodology; the possibilities for ethnicity analyses as available from the LIS/LES datasets; and the theoretical framework used to draw substantive cross-national comparisons. Section two comprises a summary of the descriptive patterns observed for selected indicators of social stratification by ethnic/nationality groups for each country, and the presentation of the SOR orderings derived from them. In section three, the possibilities for using those SOR orderings in analytical human capital style models of social stratification are considered. Lastly in section four some of the more prominent conclusions are drawn together.

Crossing boundaries: an excavation into an interdisciplinary approach to theatre making with specific reference to body mapping

ABSTRACT This study analyses through a Practice as Research methodology an interdisciplinary approach to theatre making. The capacity for the process of Body Mapping to form part of the theatre making process is assessed. Structured and unstructured improvisational techniques (including Body Mapping and contact improvisation) are used in facilitating four subjects who are actively involved in the creative process as performer-creators. The material generated from these sessions is then crafted into a performance work, as well as exposing the creative process in an exhibition of photographs and writings drawn from the improvisational workshops. The documentation is then consolidated in the form of a research report analysing the use of interdisciplinary approaches to theatre making with specific reference to Body Mapping

Investigation of long term stability in metal hydrides

It is apparent from the literature and the results of this study that cyclic degradation of AB(5) type metal hydrides varies widely according to the details of how the specimens are cycled. The Rapid Cycle Apparatus (RCA) used produced less degradation in 5000 to 10000 cycles than earlier work with a Slow Cycle Apparatus (SCA) produced in 1500 cycles. Evidence is presented that the 453 K (356 F) Thermal Aging (TA) time spent in the saturated condition causes hydride degradation. But increasing the cooling (saturation) period in the RCA did not greatly increase the rate of degradation. It appears that TA type degradation is secondary at low temperatures to another degradation mechanism. If rapid cycles are less damaging than slow cycles when the saturation time is equal, the rate of hydriding/dehydriding may be an important factor. The peak temperatures in the RCA were about 30 C lower than the SCA. The difference in peak cycle temperatures (125 C in the SCA, 95 C in RCA) cannot explain the differences in degradation. TA type degradation is similar to cyclic degradation in that nickel peaks and line broadening are observed in X ray diffraction patterns after either form of degradation
