The differential expression of male sexual behavior in the Lewis, Fischer and Sprague-Dawley rat strains

Several indices of sexual behavior were characterized for male rats of the Lewis (LEW), Sprague-Dawley (SD) and Fischer (F344) strains. Males were permitted access to a receptive female of their own strain for five 50-min sessions every fifth day. LEW males emitted longer latencies (first mount, intromission, ejaculation and post-ejaculatory interval) and lower frequencies (mounts, intromissions, ejaculations, intromission ratio) relative to F344 males, with the SD strain in general, lying intermediate. Following this assessment, males of each strain were randomly assigned to females of their own or another strain to ascertain whether differences were due to differential female receptivity. Although there were no significant differences during this phase indicative of differential receptivity, the sample size may preclude a definitive interpretation of such results. The data were discussed in the context of other behavioral differences between the strains and the possible neurobiological mechanisms underlying these differences.     

The Aftermath of Remedial Math: Investigating the Low Rate of Certificate Completion among Remedial Math Students

Nationally, a majority of community college students require remedial assistance with mathematics, but comparatively few students who begin the remedial math sequence ultimately complete it and achieve college-level math competency. The academic outcomes of students who begin the sequence but do not complete it are disproportionately unfavorable: most students depart from the community college without a credential and without transferring to a four-year institution. Interestingly, however, many of these students continue to attend the community college after they exit the remedial math sequence, sometimes for an extended period. One is led to ask why students who do not complete the sequence generally are not finding their way to an alternative credential objective that does not require college-level math competency, such as a career and technical education certificate, sometimes referred to as a vocational certificate. In this study, I explore three possible answers to this question, including difficulty navigating to the alternative credential, declining participation in the community college, and declining academic performance. I find that all three of these explanations contribute (to varying degrees) to explaining the low rate of certificate completion among remedial math students who do not achieve college-level math competency.     

Why did you do that? Teachers explain the use of legal aggression in the classroom

Teachers (n = 233) who employ aggressive classroom management strategies were asked to theorise about their use. Levels of support for three theoretical explanations for aggressive behaviour were assessed via a 26 item scale. The items loaded to three factors: Attribution Theory; Efficacy Theory and Attachment Theory. Results indicated most teachers, 42%, supported Attribution, 34% supported Efficacy, and 33% supported Attachment as an explanation for aggressive behaviour. Moreover, 14% of teachers support all theories simultaneously, whilst 27% of teachers rejected all theories. The implications of these findings are that many teachers may be theoretically blind when it comes to classroom management: hence re- rather than pro-active. The importance of this finding for professional development providers and future qualitative research design is discussed.     

The relative effectiveness of private and public schools: evidence from Kenya

ABSTRACT

This paper estimates the relative effectiveness of private and public primary schools in Kenya using data from 4,433 Grade 6 schoolchildren. Using ordinary least squares as a baseline model, we use the proportion of private schools in a district as an instrument in a Heckman two-stage correction framework, as well as propensity score matching models to correct for selection bias. There is a positive private school effect across all models. In the corrected models, we find that private school pupils outperform their public school counterparts by between .24 and .52 standard deviations.

Walking the leadership tightrope: building community cohesiveness and social capital in schools in highly disadvantaged urban communities

School leaders in highly disadvantaged urban communities across the globe walk a tightrope, caught between the needs of communities and the requirements of national policies. This article aims to enrich our understanding of the potential of school–community relationships. It examines the policy discourse on urban schools and the practice of community leadership. The policy context is one of UK and international concerns about divisions in society and the rise of political extremism: concerns which, in the UK, have led to a policy focus on community cohesion. The article offers a conceptual framework—a theory of action—as a possible road map for school leaders to manage through this complex and evolving arena of policy and practice. The template— developed through earlier work on urban schools—is underpinned by a focus on trust (as the lubricant to link communities together) and social capital (as a way of harnessing the ‘social energy’ of communities for positive good). The template is tested against the leadership of two school principals in challenging contexts in London and Greater Manchester. The author concludes that there is potential for schools to create space for the voices of the marginalised and disenfranchised to be heard. This analysis will resonate with school leaders serving disadvantaged communities in many international contexts and signals a new departure for leadership.     

Education students and their teachers: comparing views on participative assessment practices

Beliefs about the validity and merit of self‐, peer‐ and group‐assessment practices are presented from 213 pre‐service primary teachers and 30 staff who teach them. Both groups were surveyed using comparable items. A subset of seven staff participated in semi‐structured interviews. Staff were far more supportive of peer‐ and self‐assessment practices than their students with both groups indicating modest support for group assignments. While pedagogical factors best represent the staff support for engaging students in assessment of their own and their peers’ work, several staff in interviews revealed that their high level of support for peer‐assessment was closely linked to a time‐saving factor. Peer‐assessment was more often used than self‐assessment while both practices were reported to have increased over the past two to three years. These findings are consistent with the reported increase in participative assessment practices in higher education generally. An important implication of this research is that in order to optimise the use of participative assessment, staff need to better prepare their students by modelling and communicating their reasons for adopting such practices.
