Determining heterogeneous behavior for theater attendance   总被引：2，自引：1，他引：1  

Victoria Ateca-Amestoy 《Journal of Cultural Economics》2008,32(2):127-151

In this paper we propose and estimate a model of theater participation using the data contained in the 2002 Survey of Public Participation in the Arts from the USA, a dataset widely used to study the determinants of cultural participation. Our contribution relies on the use of an estimation technique that respects the count data nature of the attendance variable (number of theater performances that an individual attended) and allows for heterogeneous behavior. By using a Zero Inflated Negative Binomial Model, we can characterize two distinct behaviors for the observable attendance: a group of never-goers (who never participate) and a subpopulation that has a positive probability of attending. For this latter group, we can estimate the effect of certain personal variables on the probability of highest frequency. The results suggest that the proposed model is appropriate for estimating cultural participation.

The effects of arm crank strategy on physiological responses and mechanical efficiency during submaximal exercise     

Goosey-Tolfrey VL  Sindall P 《Journal of sports sciences》2007,25(4):453-460

The purpose of this study was to compare submaximal physiological responses and indices of mechanical efficiency between asynchronous and synchronous arm ergometry. Thirteen wheelchair-dependent trained athletes performed eight steady-state incremental bouts of exercise (0 to 140 W), each lasting 4 min, using synchronous and asynchronous arm-cranking strategies. Physiological measures included oxygen uptake (VO2), heart rate, and blood lactate concentration. The power outputs corresponding to fixed whole blood lactate concentrations of 2.0 to 4.0 mmol x l(-1) were calculated using linear interpolation. Mechanical efficiency indices - gross efficiency, net efficiency, and work efficiency - were also calculated. An analysis of variance with repeated measures was applied to determine the effect of crank mode on the physiological parameters. Oxygen uptake was on average 10% lower (P < 0.01), and both net efficiency (P < 0.01) and gross efficiency (P < 0.01) were higher, during the asynchronous strategy at both 60 and 80 W (gross efficiency: 16.9 +/- 2.0% vs. 14.7 +/- 2.4% and 17.5 +/- 1.8% vs. 15.9 +/- 2.6% at 60 and 80 W respectively). There were no differences in heart rate, blood lactate concentration or power output at either of the blood lactate reference points between the asynchronous and synchronous strategies (P > 0.05). In conclusion, test specificity is an important consideration. If a synchronous strategy is to be adopted, it is likely to result in lower efficiency than an asynchronous strategy. The exercise testing scenario may help dictate which method is ultimately chosen.  相似文献   

The role of hurtful and healing messages on eating disorder symptomology and recovery     

Victoria Orrego Dunleavy  Ekaterina Malova 《Qualitative Research Reports in Communication》2019,20(1):58-66

This study analyzed how clinically diagnosed women with eating disorders described the hurtful messages from parents, siblings, and peers that triggered eating disorder symptomology as well as the healing messages that assisted with coping and recovery. Three themes overlapping across all groups were revealed for hurtful messages: 1) critical, 2) social modeling, and 3) direct comparison. Our findings show that fathers, siblings, and peers similarly used teasing. Other points of distinction were uncovered for fathers: aggressive messages and denial of eating disorder. Competition with female siblings and friends was also a triggering factor for young females with eating disorders. Four distinct categories of healing messages were identified: 1) emotional, 2) instrumental, 3) informational, and 4) appraisal. Point of distinction for friends’ and siblings’ healing messages was absence of negative comments about weight and appearance. Results were able to encapsulate both helpful/supportive and hurtful/unsupportive messages, and these findings will be helpful for treatment centers who may incorporate them in recovery programs.  相似文献   

Patterns and organizing perspectives: A view of expertise     

Victoria Genberg 《Teaching and Teacher Education》1992,8(5-6)

This paper presents two theoretical conceptualizations of mastery. The first, based on an information-processing approach, emphasizes hierarchically structured knowledge and its linear application to solve problems. The second, an intuitive approach, considers mastery as the elaboration of knowledge of situations. This knowledge is defined in terms of understanding the patterns of critical relationships present in situations, and in which appropriate behavior is an integral part of the pattern. Empirical findings comparing novices and experts in various domains, including teaching, are briefly reviewed. A summary follows of two conceptual models of the progression from novice to expert, those of Anderson, and Dreyfus and Dreyfus. The author proposes a scale of mastery of teaching based on a synthesis of the above models.  相似文献   

Expert Teams in the Academic Library: Going Beyond Subject Expertise to Create Scaffolded Instruction     

Christina L. Wissinger  Victoria Raish  Rebecca K. Miller  Steve Borrelli 《图书馆管理杂志》2018,58(4):313-333

This article explores the way librarians define, leverage, and amplify expertise in a twenty-first century academic library. An expert team comprised of a nursing librarian, online learning librarian, information-literacy librarian, and assessment librarian sorted the learning outcomes from the Information-Literacy Competency Standards for Nursing created by the Health Sciences Interest Group taskforce of the Association of College and Research Libraries (ACRL) by grade-levels. Results found distinguishing experts within a library supports the customization of scaffolded instruction. Additionally, using expert teams in academic libraries supports the larger mission of universities to integrate libraries into teaching and research.  相似文献

The relationship between implicit theories of intelligence,attainment and socio-demographic factors in a UK sample of primary school children     

Frances Warren  Emily Mason-Apps  Sherria Hoskins  Victoria Devonshire  Mathilde Chanvin 《British Educational Research Journal》2019,45(4):736-754

Research emerging from the USA suggests that holding an incremental theory of intelligence (growth mindset) has a positive impact on academic success. However, limited empirical work has explored this relationship in a UK sample, and there has been a lack of research into the antecedents which might influence the development of certain intelligence beliefs. This study aimed to explore these gaps in the existing literature. Data was collected from 710 9-year-old pupils (UK Year 5). Participants completed attainment tests in Maths and English, and a questionnaire to assess their implicit theories of intelligence (mindset). Socio-demographic information—including gender, ethnicity, free school meal (FSM) status and special educational needs (SEN) status—was also collected. Results showed that pupils eligible for FSM or SEN endorsed more of an entity theory of intelligence than pupils not eligible for either. Analysis of the whole sample showed that attainment significantly correlated with implicit theories of intelligence, however, this relationship did not exist for children with FSM or SEN status. These findings help to elucidate the relationship between implicit theories of intelligence and attainment in the UK, but also suggest the importance of external support in potentially facilitating pupils’ belief systems. Results are discussed in relation to avenues for targeted intervention.  相似文献   

The Earlier the Better? Individual Participant Data and Traditional Meta-analysis of Age Effects of Parenting Interventions     

Frances Gardner  Patty Leijten  G.J. Melendez-Torres  Sabine Landau  Victoria Harris  Joanna Mann  Jennifer Beecham  Judy Hutchings  Stephen Scott 《Child development》2019,90(1):7-19

Strong arguments have been made for early intervention for child problems, stating that early is more effective than later, as the brain is more malleable, and costs are lower. However, there is scant evidence from trials to support this hypothesis, which we therefore tested in two well-powered, state-of-the-art meta-analyses with complementary strengths: (a) Individual participant data (IPD) meta-analysis of European trials of Incredible Years parenting intervention (k = 13, n = 1696; age = 2–11); (b) Larger, trial-level robust variance estimation meta-analysis of a wider range of parenting programs (k = 156, n = 13,378, M_age = 2–10) for reducing disruptive behavior. Both analyses found no evidence that intervention earlier in childhood was more effective; programs targeted at a narrower age range were no more effective than general ones.  相似文献
