PARTY IDENTIFICATION AND ATTITUDES TOWARDS HOMOSEXUALS IN GREAT BRITAIN     

Hayes  Bernadette C.; Moran-Ellis  Jo 《Int. Journal of Public Opinion Research》1995,7(1):23-39

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 varioussocio–demographic 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   

Intra-task variability of trunk coordination during a rate-controlled bipedal dance jump     

Smith JA  Siemienski A  Popovich JM  Kulig K 《Journal of sports sciences》2012,30(2):139-147

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   

Active relatives and health-related physical fitness in European adolescents: The HELENA Study

Abstract High physical fitness in childhood and adolescence is positively associated with favourable health-related outcomes. Our aim was to examine the relationship between relatives' (father, mother, brother, sister, and best friend) physical activity engagement and encouragement on adolescents' physical fitness. Adolescents were part of the HELENA study, a multi-centre study conducted in 10 cities from nine European countries in 2006-2008. Participants were 3288 adolescents (48% boys, 52% girls) aged 12.5-17.5 years with valid data on at least one of the three fitness variables studied: muscular strength (standing long jump), speed/agility (4×10 m shuttle run), and cardiorespiratory fitness (20 m shuttle run). The adolescents reported their relatives' physical activity engagement and encouragement. Analysis of covariance showed that relatives' physical activity engagement (father, mother, brother, and best friend) was positively related to cardiorespiratory fitness (P?相似文献   

Research and development, cash flow, agency and governance: UK large companies     

Ciaran Driver  Maria João Coelho Guedes 《Research Policy》2012,41(9):1565-1577

This paper investigates the determinants of R&D expenditure using a sample of UK listed companies with the highest spend from 2000 to 2005. We investigate the effect of corporate governance and ownership on R&D, using panel data. The results provide some evidence that more governance tends to depress R&D activity, a finding that is robust to whether a composite or disaggregated index of governance is used. One innovation of the paper is that we treat agency and finance effects interactively. The ownership stake of the CEO appears to be supportive for R&D.  相似文献   

Does sensorimotor training improve the static balance of young volleyball players?     

Pau M  Loi A  Pezzotta MC 《Sports biomechanics / International Society of Biomechanics in Sports》2012,11(1):97-107

The aim of this investigation is to assess the effectiveness of a 6-week balance training (BT) protocol, integrated in regular training sessions, on postural sway of young female volleyball players (n = 26, age 13.0 +/- 0.2 years) divided into two groups (intervention and control; 13 per group). Trials were performed for bipedal and unipedal stance conditions before and after the BT protocol, using a pressure platform to collect center-of-pressure (COP) time series that were processed to calculate sway area, COP path length, and maximum displacement range in anteroposterior and mediolateral directions. The intervention group exhibited smaller sway areas in eyes closed conditions (intervention = 42.76 mm2, control = 67.60 mm2; p < 0.05) and Romberg quotients (intervention = 1.11 mm, control = 1.82 mm) in bipedal stance, while all the other parameters were unaffected. BT also reduced sway area (intervention = 122.70 mm2, control = 187.18 mm2) and anteroposterior COP displacements (intervention = 20.18 mm, control = 22.38 mm) of the non-dominant limb for single-leg stance. No significant change was found for the dominant limb. Although it is possible to hypothesize a beneficial effect of BT on young athletes, further investigations are required to clarify its actual effect on balance performance with respect to normal volleyball training.  相似文献   

An analytical investigation of the painting technique of Italian Renaissance master Lorenzo Lotto     

Kamilla B. Kalinina  Ilaria Bonaduce  Maria Perla Colombini  Irina. S. Artemieva 《Journal of Cultural Heritage》2012,13(3):259-274

This paper presents the first extensive investigation of the composition of both the organic and inorganic media used by Lorenzo Lotto, one of the outstanding artists of the Italian Renaissance in the early 16th century. By investigating four paintings from The State Hermitage Museum collection (Saint-Petersburg, Russia), new insights into the artist's painting techniques were obtained, which contribute to our understanding of the transition from egg tempera to oil painting techniques that took place in Italian paintings between the 15th to the mid 16th century. Inorganic materials were determined using SEM-EDX and PLM, revealing information on the artist's palette. Of particular note was the powdered colourless glass found in the priming layer of the Madonna delle Grazie, which was most likely used as dryer. Organic materials were analysed in individual paint layers using GC-MS, and revealed a mature use of drying oils as paint binders, skilfully mixed with other organic materials and inorganic driers, to obtain the desired aesthetical and technical qualities of the paint. The study revealed that Lotto used the tempera grassa technique through most of his creative life.  相似文献   

Cinders in Snow? Indigenous Teacher Identities in Formation     

Jo‐Anne Reid  Ninetta Santoro 《Asia-Pacific Journal of Teacher Education》2006,34(2):143-160

The identity work engaged in by Indigenous teachers1 1. We use the term ‘Indigenous’ here to include Aboriginal and Torres Strait Islander people working in Australian schools, although most of our informants to date are from Victoria, NSW and Queensland, who do not use the term ‘Indigenous’ when identifying themselves and their communities, preferring ‘Aboriginal’, ‘Koori’ or ‘Murri’.. View all notes 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
