This paper addresses the positioning of science, technology, engineering and mathematics (STEM) outreach programmes within universities’ operations. Though universities in many respects form a rather homogenous international community, there is wide diversity in regard to the provision of STEM outreach by different institutions. To explain this diversity, a conceptual framework was developed by using the Theory of Legitimacy as an organising concept. The framework considers two opposing scenarios that form a continuum between them, namely: ‘top‐down’ initiative by the university governance versus ‘bottom‐up’ grass‐roots initiative. Using the Theory of Legitimacy, internal and external outreach relationships are characterised and explained under the two scenarios. The framework was applied to two settings chosen due to their essential differences in outreach provision, namely, Australia and Israel. The differences that were found in internal and external legitimacy provide a useful lens for examining the low‐performing, fragile system in Australia as compared with the high‐performing, thriving system in Israel. 相似文献

Dyslexia is a complex reading and writing disorder with a strong genetic component. In a German case-control cohort, we studied
the influence of the suspected dyslexia-associated gene DCDC2. For the first time in a German cohort, we describe association
of a 2445 basepair deletion, first identified in an American study. Evidence of association for three DCDC2 single nucleotide
polymorphisms (rs807724, rs793862, rs807701), previously identified in German or American cohorts, was replicated. A haplotype
of these polymorphisms showed evidence for association as well. Thus, our data further corroborate association of DCDC2 with
dyslexia. Analysis of functional subgroups suggests association of investigated DCDC2 variants mainly with nondysphonetic,
nonsevere, but probably dyseidetic (surface) dyslexia. Based on the presumed function of DCDC2, our findings point to a role
of impaired neuronal migration in the etiology of the disease.

This article investigates how schoolteachers’, school leaders’ and college teachers’ involvement affects placement schools as professional learning communities. Norwegian teacher education is used as a case. The first part builds on a survey among schoolteachers and mentors at 111 placement schools in Norway. It documents great variety in the level of engagement. Interviews with mentors, school leaders and college teachers reveal how cooperation between colleges and placement schools, as well as the school leaders’ commitment, influences the quality of placement. The school leaders’ role proves to be important in developing the schools as professional learning communities, and they seem to have a significant impact on the work of the mentors. The data also show that there is a need for a more substantial cooperation between college teachers and mentors about the student teachers’ professional development as well as a need for a more systematic integration of learning in the two learning contexts. 相似文献

The goal of this article is to examine the strategic choices of firms collecting consumer data online and to identify the roles and obligations of the actors within the current network of online tracking. In doing so, the focus shifts from placing the onus on individuals to make an informed choice, to justifying the roles and responsibilities of firms when gathering, aggregating, and using consumers' interests or behavior online. Firms online are uniquely positioned to undercut or to respect privacy expectations within three possible roles: as a member of a supply chain of information traders, within a network of surveillance online, and as an arm of law enforcement. These firms benefit from aggregating and analyzing consumer data and have an associated responsibility to not only minimize the harm to consumers but also to enact change where the firm is in the most knowledgeable and powerful position. 相似文献

This study investigates gender differences in basic numerical skills that are predictive of math achievement. Previous research in this area is inconsistent and has relied upon traditional hypothesis testing, which does not allow for assertive conclusions to be made regarding nonsignificant findings. This study is the first to compare male and female performance (N = 1,391; ages 6–13) on many basic numerical tasks using both Bayesian and frequentist analyses. The results provide strong evidence of gender similarities on the majority of basic numerical tasks measured, suggesting that a male advantage in foundational numerical skills is the exception rather than the rule. 相似文献
