Legislative activity and controversy concerning the issue ofhomosexual rights and practices has intensified in Britain overthe last decade. Despite this increase in intensity, however,the question of mass public opinion in relation to homosexualrights and practices has received little empirical investigation.In an effort to remedy this situation, this paper focuses onthe influence of party identification in determining publicattitudes towards homosexuals. Using data from the British SocialAttitudes Surveys, the results suggest that although party identificationexerts an independent and statistically significant effect onattitudes towards homosexuals, in all cases, however, theseeffects are both secondary and variable. Other equally, if notmore salient, determinants include: gender, education, age,occupation, and type of homosexual relationship. Of these varioussociodemographic variables, both age and education standout as having the strongest and most consistent effect. In otherwords, at least as far as current British society is concerned,anti-homosexual views are most prevalent among both older individualsas well as the lesser educated. 相似文献

The present work describes the operation and simulation of a microfluidic laminar-flow mixer. Diffusive mixing takes place between a core solution containing lipids in ethanol and a sheath solution containing aqueous buffer, leading to self assembly of liposomes. Present device architecture hydrodynamically focuses the lipid solution into a cylindrical core positioned at the center of a microfluidic channel of 125 × 125-μm2 cross-section. Use of the device produces liposomes in the size range of 100–300 nm, with larger liposomes forming at greater ionic strength in the sheath solution and at lower lipid concentration in the core solution. Finite element simulations compute the concentration distributions of solutes at axial distances of greater than 100 channel widths. These simulations reduce computation time and enable computation at long axial distances by utilizing long hexahedral elements in the axial flow region and fine tetrahedral elements in the hydrodynamic focusing region. Present meshing technique is generally useful for simulation of long microfluidic channels and is fully implementable using comsol Multiphysics. Confocal microscopy provides experimental validation of the simulations using fluorescent solutions containing fluorescein or enhanced green fluorescent protein. 相似文献

In this study, we investigated trunk coordination during rate-controlled bipedal vertical dance jumps. The aims of the study were to investigate the pattern of coordination and the magnitude of coordination variability within jump phases and relative to phase-defining events during the jump. Lumbar and thoracic kinematics were collected from seven dancers during a series of jumps at 95 beats per minute. The vector coding technique was used to quantify the pattern and variability of trunk coordination. Coordination was predominantly anti-phase during propulsion and landing. Mean coordination variability peaked just before the landing phase and at the transition from landing to propulsion phases, and was lowest during the propulsion phase just before toe-off. The results indicate that peaks in variability could be explained by task and phase-specific biomechanical demands. 相似文献

The identity work engaged in by Indigenous teachers1 in school settings is highlighted in a study of Australian Indigenous teachers. The construction of identity in home and community relationships intersects with and can counteract the take up of a preferred identity in the workplace. In this paper we analyse data from interviews with Indigenous teachers, exploring the interplay between culture and identity. We foreground the binary nature of racial assignment in schools, demonstrate how this offers contradictory constructions of identity for Indigenous teachers, and note the effects of history, culture and location in the process of forming a teaching ‘self’. 相似文献

A concise review is presented of the essential elements of the book publishing and bookselling business in a complex and diverse
market. Demographics create the diversity while Arabic is the one language spoken across a multitude of different countries.
Three features are common to all of these countries and they are: the dominance of English as the second language, education
has and will remain to be a priority, and economic pressures cause price sensitivity to be a major challenge especially in
the educational market segments. It is the price sensitivity as a key factor for the lack of respect for intellectual property
and copyright regulations. A review of distribution and retail stores is a very important topic in relation to this complex
collection of countries. The emergence of e-books is discussed especially in the educational, professional and reference market
segments. Finally, there is a review of the Arabic language publishers and local book fairs to bring this article to closure. 相似文献

This paper reports on an evaluation of a drama‐based Healthy Relationships programme on domestic violence delivered on a pilot basis to Year 8 pupils. The programme included a play delivered by a local theatre‐in‐education company followed by a series of weekly workshops. Eighty‐five pupils in a secondary school located in an area with high rates of social exclusion participated in the programme and the evaluation. Pupils completed questionnaires immediately before and after the programme and one year after the programme had finished. Thirteen pupils also took part in gendered discussion groups, which considered their views and opinions concerning the play and the workshops. The evaluation indicated that the programme was successful in enhancing pupils' understandings of domestic violence up to one year after delivery. Pupils responded well to the use of drama as a medium for learning, and some young people were able to demonstrate that they had developed positive ideas about healthy relationships. However, there was evidence of uncertainly for some young people with regard to the gendered nature of domestic violence following the programme. The discussion highlights this issue and identifies additional recommendations for both future research and future programmes. 相似文献

Indigenous voices are largely silent in the outdoor education and adventure therapy literature. The purpose of this research collaboration was to understand how a 10-day outdoor adventure leadership experience (OALE) may promote resilience and well-being for Indigenous youth through their participation in the program. The process was examined through a community-based participatory research project that sought insight from the perspectives of one First Nations community in Canada. The OALE was implemented with six different groups for a total of 43 youth participants (ages 11.9–18.7 years) from Wikwemikong Unceded Indian Reserve in northeastern Ontario. Field data were collected from multiple sources including participant interviews, journals, focus groups, and talking circles. Using a critical ethnographic lens, we analyzed the data inductively to understand how the OALE promoted resilience and well-being. We listened to Indigenous voices, adhered to principles of Indigenous coding for thematic content and respected Indigenous ways of knowing for interpreting results. The process of connecting to the Good Life (Anishinaabe Bimaadziwin) or waking up (nsidwaaswok) to the Good Life emerged as the dominant theme. Connecting to the Good Life may offer a simple yet compelling way to understand the net impact of the OALE. 相似文献

Although different writing courses exist because of the different forms and purposes of writing they teach, some continuity between composition and business/technical communication would allow students to move more readily from one course to the next, while clarifying for them that writing is primarily a system of options based on analyses of situations, readers, obstacles, and goals. In this article, I call for that kind of continuity not only in pedagogy but also in research. Explaining the value of connections in pedagogy and research between composition and professional communication studies, I conclude with various questions and avenues for further research. 相似文献
