Gay On-Screen: The Relationship Between Exposure to Gay Characters on Television and Heterosexual Audiences' Endorsement of Gay Equality     

Bradley J. Bond  Benjamin L. Compton 《广播与电子媒介杂志》2015,59(4):717-732

The current study, grounded in the parasocial contact hypothesis, employed a survey of emerging adults to investigate the relationship between exposure to gay characters on television and heterosexuals' endorsement of gay equality. A positive relationship existed between exposure to on-screen gay characters and gay equality endorsement. The relationship was stronger for racial minority participants than for White participants, and for participants who had no or few interpersonal relationships with openly gay individuals than for participants who had more than three respective relationships. Results are discussed in terms of the parasocial contact hypothesis and television as an agent of social change.  相似文献   

Hybrid capillary-inserted microfluidic device for sheathless particle focusing and separation in viscoelastic flow     

Jeonghun Nam  Justin Kok Soon Tan  Bee Luan Khoo  Bumseok Namgung  Hwa Liang Leo  Chwee Teck Lim  Sangho Kim 《Biomicrofluidics》2015,9(6)

A novel microfluidic device which consists of two stages for particle focusing and separation using a viscoelastic fluid has been developed. A circular capillary tube was used for three-dimensional particle pre-alignment before the separation process, which was inserted in a polydimethylsiloxane microchannel. Particles with diameters of 5 and 10 μm were focused at the centerline in the capillary tube, and the location of particles was initialized at the first bifurcation. Then, 5 and 10 μm particles were successfully separated in the expansion region based on size-dependent lateral migration, with ∼99% separation efficiency. The proposed device was further applied to separation of MCF-7 cells from leukocytes. Based on the cell size distribution, an approximate size cutoff for separation was determined to be 16 μm. At 200 μl/min, 94% of MCF-7 cells were separated with the purity of ∼97%. According to the trypan blue exclusion assay, high viability (∼90%) could be achieved for the separated MCF-7 cells. The use of a commercially available capillary tube enables the device to be highly versatile in dealing with particles in a wide size range by using capillary tubes with different inner diameters.  相似文献   

The role that schools hold in supporting young people with selective mutism: a systematic literature review     

Joe White  Caroline Bond 《Journal of Research in Special Educational Needs》2022,22(3):232-242

Schools are expected to hold an increasingly central role in co-ordinating support for children with mental health needs. However, the role that schools hold in supporting pupils with selective mutism (SM) is complex. Through a Critical Interpretive Synthesis (CIS), this review explores the multidimensional role which educational settings hold in supporting children with SM. Key databases were searched (PsycInfo, British Education Index, Education Resources Information Center, British Library EThOS and Google Scholar) and a conceptual map, informed by experienced practitioners, guided additional purposive searching with a focus on conceptual saturation. A total of twenty-four papers were identified following a further process of appraisal. Reciprocal Translational Analysis (RTA) found that schools hold a tripartite role in supporting children with SM: this incorporated developing a shared understanding of the disorder, engaging in effective (and often multi-professional) planning, and offering direct support through adapting provision and facilitating individual intervention. Through realising this role, schools and educational settings might transform the support currently available for children and young people with SM. Implications for practice, policy and future research also emerged. This included a clear need for enhanced teacher understanding of SM, arguably at the level of initial teacher training (ITT).  相似文献

Learning to use the Internet as a study tool: a review of available resources and exploration of students' priorities     

Bond CS  Fevyer D  Pitt C 《Health information and libraries journal》2006,23(3):189-196

BACKGROUND: The Internet is a valuable information tool, but users often struggle to locate good quality information from within the vast amount of information available. OBJECTIVE: The aim of the study was to identify the online information resources available to assist students develop Internet searching skills, and to explore the students' priorities in online guides. METHODS: A qualitative approach was adopted with two phases. The first was a structured search of available online study skills resources. The second comprised 10 group interviews with a total of 60 students at all stages of five undergraduate health and social care related courses at a UK university. RESULTS: The study found that there were good online guides available, but that, perversely, the better guides tended to require the best searching skills to locate them. A few students were enthusiastic about using online support, however the majority felt that if they had the skills to locate such resources they wouldn't use a study guide to improve these skills, and if they did not have the skills they would not think of using an online guide to develop them. CONCLUSIONS: Students wanted assistance when they had problems or questions, rather than sites that offered structured learning experiences. Personal support rather than virtual support was also considered to be most important to the students in this study.  相似文献   

Understanding outcome-based education changes in teacher education: evaluation of a new instrument with preliminary findings     

Christopher Deneen  Gavin T.L. Brown  Trevor G. Bond  Ronnie Shroff 《Asia-Pacific Journal of Teacher Education》2013,41(4):441-456

Outcome-based education (OBE) is a current initiative in Hong Kong universities, with widespread backing by governments and standards bodies. However, study of students’ perceptions of OBE and validation of understanding these perceptions are lacking. This paper reports on the validation of an OBE-specific instrument and resulting preliminary findings. Instrument responses (n = 89) were analysed using Rasch and exploratory/confirmatory factor analyses. Both approaches identified two dimensions (i.e. evaluation and comparison). Challenges and modifications to the instrument items and their relationships to constructs are discussed. Preliminary findings suggest students did not perceive significant differences between OBE and traditionally organised courses. Lack of explicit discussion of OBE with the students may have denied students the ability to make fully informed evaluations of OBE innovations. Implications for instrument validation and evaluation of initiatives in an OBE context are discussed as is the broader issue of transparency in teacher education curriculum design and implementation.  相似文献   

Exploring the nature of the relation between interest and comprehension     

Tan Bee Tin 《Teaching in Higher Education》2013,18(5):525-536

This paper examines the complex relation between interest and comprehension recorded by postgraduate students in a language teacher education programme at various stages of two-hour lectures. The quantitative analysis suggests that its relationship with comprehension changes as the lecture continues. The analysis is also triangulated with the qualitative responses reported by students at different stages of the lecture. The type of comprehension that co-occurs with increasing interest differs from the type of comprehension that co-occurs with maintaining interest. Although the effect of comprehension on interest is low at the beginning of the lecture, its effect is more frequently noted as important at the later stages of the lecture. Postdictability (i.e., the ability to determine after the fact that unpredictability and difficulty that have been raised in the earlier parts of the lecture hang together and make sense) seems important in increasing interest, especially at the later stages of the lecture.  相似文献   

The roles of teacher efficacy in instructional innovation: its predictive relations to constructivist and didactic instruction     

Youyan Nie  Gim Hoon Tan  Albert Kienfie Liau  Shun Lau  Bee Leng Chua 《Educational Research for Policy and Practice》2013,12(1):67-77

Constructivist instruction has been implemented in the current instructional innovation in Singapore. Large scale survey study was conducted to examine the roles of teacher efficacy in implementing the innovative constructivist instruction. The results showed that the positive correlation between teacher efficacy and constructivist instruction was stronger than the correlation between teacher efficacy and didactic instruction. The study suggests that policy makers and school leaders should try to improve teacher’s efficacy beliefs so that innovative instruction could be effectively implemented by school teachers.  相似文献
