The domestic dog is an ideal model species in which to study the genetic and environmental factors that influence play behavior. Dogs exist in a wide variety of breeds and frequently engage in multiple forms of play. In the present study, we investigated whether the levels of solitary and social play differed between dogs of three breed types with distinct predatory motor pattern sequences (herding dogs, retrievers, and livestock guarding dogs [LGDs]). Furthermore, we investigated how environmental factors (social and nonsocial contexts) influenced play in dogs of these breed types. Groups of breed-matched dyads with working experience and of equivalent age, sex, and neuter status ratios were exposed to four experimental test conditions and two control conditions in randomized orders. With respect to solitary play, environmental context did have a significant effect, with toys reliably producing the highest levels of solitary play across all breed types. Retrievers engaged in significantly higher levels of solitary play overall than LGDs, and there was a trend in comparison to herding dogs. In contrast, neither environmental context nor breed had a significant effect on social play levels; however, neuter status of the dyads did have a significant effect on social play, with mixed-status dyads engaging in significantly higher levels of social play than same-status dyads. Our findings provide experimental evidence for identifying proximate, environmental stimuli that reliably facilitate social and solitary play and discuss possible genetic (i.e., breed type) and lifetime influences on the form of play in domestic dogs.  相似文献   

Perpetrating disaffection: schooling as an international problem     

Clive Harber 《Educational studies》2008,34(5):457-467

This paper argues that, despite evidence of widespread disaffection, school is often regarded as the default position for educational provision, a given good. If there is disaffection with, and resistance to, schooling, then it is pupils and parents that are the problem, not school itself. Yet there is considerable evidence that schooling does not necessarily or automatically benefit either society as a whole or the individuals who attend and that, as a result, it creates disaffection with itself. Rejection of schooling is therefore very far from being an irrational or ill‐considered act. The paper reviews evidence supporting this argument including both the failure of schools to protect young people from danger and violence and also their direct role in actively perpetrating violence and threatening the safety of those they are there to protect. The paper ends by arguing that disaffection with schooling stems from its fundamental nature and purposes which have been shaped by its historical origins. While schooling remains as it is, disaffection and resistance will continue to be an inbuilt and often logical response.  相似文献   

The public returns to public educational investments in African-American males     

Henry M. Levin  Clive Belfield  Peter Muennig  Cecilia Rouse 《Economics of Education Review》2007,26(6):699

This paper calculates the public savings (financial benefits) from greater public investments in the education of African-American males. Over one-fifth of each age cohort of black males in US is not a high school graduate. We identify five interventions that would—based on credible research—increase the graduation rate; we also report the public cost of each intervention. We then calculate the lifetime public benefits in terms of increased tax revenues and lower spending on health and crime. In present values, for a black male aged 20, these public benefits amount to $256,700 per new graduate and the median intervention would cost only $90,700. The benefit/cost ratio is 2.83. Simply equating the high school graduation rate of black males with that of white males would yield public savings of $3.98 billion for each age cohort. These results suggest that increased investments in education for black males at risk of dropping out of high school should be an economic priority.  相似文献   

One Size Fits All? Teacher Appraisal in a Chinese Culture   总被引：1，自引：0，他引：1  

Allan Walker  Clive Dimmock 《Journal of Personnel Evaluation in Education》2000,14(2):155-178

In this article we suggest that the penetration of Western policies and practices—in particular, teacher appraisal—into Asian cultural contexts needs to be questioned. We begin by making a general case for considering the influence of societal culture on educational policies and practices, and a more specific argument for assessing its role in the implementation of teacher appraisal in different cultures. We argue that it may be unwise simply to clone appraisal practices in contexts and cultures quite different from those in which they are chartered. The study briefly reviews the status of teacher appraisal in Hong Kong, given that in the next few years all Hong Kong schools must implement appraisal schemes, a fact causing considerable consternation. We then suggest that the most common forms of appraisal being promoted and implemented in Hong Kong are based on traditional Anglo-American understandings and practices. This leads to a discussion of the possible influence exerted by culture on teacher appraisal in the Chinese society of Hong Kong. Noteworthy features of Hong Kongs culture are collectivism and high power distance, both of which are sufficiently different from Anglo-American cultures to suggest that the forms taken by teacher appraisal in those countries may be inappropriate for Hong Kong. In the final section, we briefly discuss a number of issues that, it is suggested, deserve consideration when Hong Kong schools design and implement teacher appraisal schemes. As we stress throughout the study, our discussion is not intended to be definitive. Rather, we hope it will stimulate discussion and research into discovering more culturally sensitive ways of appraising teachers in different parts of the world.  相似文献

The privatization and marketization of US schooling     

Clive R. Belfield 《Zeitschrift für Erziehungswissenschaft》2002,5(2):222-240

This paper describes the trend towards the privatization and marketization of US schooling across three domains. We begin by describing the trend in recent pro-market policy reforms — proposed or enacted — to US schooling. This reform trend can be explained in terms of the growing importance of economic theory and economic evidence in social and political discourse. Briefly, we review mainstream economic theory and evidence to see what general lessons can be drawn, with a focus on productive efficiency. In the main section of the paper, we look at the direct evidence for US schooling not only in terms of the productive efficiency of schools, but also equity in schools, freedom of choice for parents and students, and the social cohesion produced by schools. Our review reaches a number of conclusions which suggest that the trend toward privatization and marketization may generate greater productive efficiency. Although the economic analysis is deficient in several ways and may have limited pertinence for social goods such as education, it highlights the need for strong and effective systems of accountability. Regardless of whether the advantages outweigh the disadvantages, however, it may be difficult to prevent further steps toward marketization.  相似文献

Time to embrace the complexity when analysing GPS data? A systematic review of contextual factors on match running in rugby league     

Nicholas Dalton-Barron  Sarah Whitehead  Gregory Roe  Cloe Cummins  Clive Beggs  Ben Jones 《Journal of sports sciences》2020,38(10):1161-1180

ABSTRACT

This systematic review aimed to identify and summarise associations between currently identified contextual factors and match running in senior male professional rugby league. Eligible articles included at least one contextual factor and used GPS to measure at least one displacement variable within competitive senior, male, professional rugby league matches. Of the 15 included studies, the identified contextual factors were grouped into factors related to individual characteristics (n = 3), match result (n = 4), team strength (n = 2), opposition strength (n = 3), match conditions (n = 6), technical and tactical demands (n = 6), spatial and temporal characteristics (n = 7), and nutrition (n = 1). Speed was the most commonly reported measure of match running (100%), followed by distance (47%), and acceleration (20%). Inconsistencies were found between studies for most contextual factors on match running. Higher speeds were generally associated with higher fitness, encountered earlier in the match and whilst defending. All 15 studies utilised a univariate approach to quantify associations of a contextual factor. The inconsistencies found in the associations of given contextual factors highlight the complex and multi-faceted nature of match running. Therefore, practitioners should consider contextual factors when analysing and interpreting GPS data.  相似文献

Attitudes to wetland restoration in Oxfordshire and Cambridgeshire,UK     

Donna Rispoli  Clive Hambler 《International Journal of Science Education》2013,35(5):467-484

Contemporary attitudes to wetlands were examined in two sites in Britain, to assess perceptions and thus educational failings as a barrier to wetland restoration. Results showed that adults' attitudes were more positive than previous literature suggests: 56% were aware of the importance of wetlands for biodiversity, and 73% were supportive of their restoration. Social groups had significantly different attitudes to wetlands (p < 0.002), which may result largely from a difference between farmers and the public (p < 0.001). Additionally a near-significant difference (p < 0.08) was detected between genders, with woman possibly more positive. Motivation for wetland conservation tended to be ethical, with 74% willing to pay, and 71% willing to vote, for wetland conservation. Whilst larger surveys are required to assess the generality of these results, there is reason for optimism that some form of education is improving public perception, despite concerns about negative conditioning amongst children (Anderson and Moss 1993).  相似文献
