The influence of breed and environmental factors on social and solitary play in dogs (<Emphasis Type="Italic">Canis lupus familiaris</Emphasis>)

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.     

Perpetrating disaffection: schooling as an international problem

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.     

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

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.     

Ally,friend, or mentor? Creating and maintaining effective cross-class alliances

This essay (re)examines the notion of intercultural alliances in one U.S. nonprofit organization trying to end poverty. The nonprofit, referred to as Transforming Poverty Partnerships, has built their program around building relationships between people in poverty and middle-class “Allies.” This analysis reveals a number of problematic themes that emerge from previous conceptions of cross-class alliances and implications for improving such alliances within various contexts.     

Where can your passport take you? Teaching citizenship,mobility, and identity

Courses: Intercultural Communication, Culture and Conflict, International Conflict and Alliance Building

Objectives: After completing this single-class activity, students should be able to (1) describe the concepts of identity, citizenship, and mobility; (2) empathize with the everyday struggles of students who hold citizenship outside of their “homeland”; and (3) explain how intersectionality influences an individual’s ability to traverse national borders.     

What do you recommend? Implementation and analyses of collaborative information filtering of web resources for education

This article examines results from one pilotstudy and two empirical studies of acollaborative filtering (CF) system applied ineducational settings. CF is a populartechnology in electronic commerce, whichleverages the interests of entire communitiesto provide targeted, personalizedrecommendations of interesting products orresources to individuals. In electroniccommerce, entertainment, and related domains,CF has proven an accurate and reliable tool;yet educational applications remain limited.From analyses of data from these three studies,we believe that CF holds promise in educationnot only for the purposes of helping learnersand educators find useful resources forlearning, but as a means of bringing togetherpeople with similar interests and beliefs, andpossibly as an aid to the learning processitself.

One Size Fits All? Teacher Appraisal in a Chinese Culture

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.     

An Exploratory Analysis of Differential Item Functioning and Its Possible Sources in a Higher Education Admissions Context

We analyzed a pool of items from an admissions test for differential item functioning (DIF) for groups based on age, socioeconomic status, citizenship, or English language status using Mantel-Haenszel and item response theory. DIF items were systematically examined to identify its possible sources by item type, content, and wording. DIF was primarily found in the citizenship group. As suggested by expert reviewers, possible sources of DIF in the direction of U.S. citizens was often in Quantitative Reasoning in items containing figures, charts, tables depicting real-world (as opposed to abstract) contexts. DIF items in the direction of non-U.S. citizens included “mathematical” items containing few words. DIF for the Verbal Reasoning items included geocultural references and proper names that may be differentially familiar for non-U.S. citizens. This study is responsive to foundational changes in the fairness section of the Standards for Educational and Psychological Testing, which now consider additional groups in sensitivity analyses, given the increasing demographic diversity in test-taker populations.
