Mechanisms for turn alternation in woodlice (Porcellio scaber): The role of bilaterally asymmetrical leg movements     

R. N. Hughes 《Learning & behavior》1985,13(3):253-260

Angles of free turn were observed in woodlice (Porcellio scaber) after they had been forced to turn left or right in runways. Alternation angles were increased by greater forced-turn angles and number of successive forced turns in one direction. Removal of one or both antennae had no effect on alternation. It was also repeatedly observed that the closer a woodlouse remained to the far wall while traveling along the exit alley of a runway, the greater was its angle of alternation. However, orientation toward this far wall bore no relation to alternation. When given three successive left or right forced turns followed by a fourth in the opposite direction, woodlice moved further away from the exit-alley far wall and repeated the last forced turn at the choice area. Along with results of the other experiments, this result in particular supported an explanation for woodlouse alternation based on bilaterally asymmetrical leg movements (BALM) arising from the negotiation of forced turns. Such asymmetry is seen as biasing an animal to turn in the opposite direction to a preceding forced turn.  相似文献   

Complicating methodological transparency     

Sarah Bridges-Rhoads  Jessica Van Cleave  Hilary E. Hughes 《International journal of qualitative studies in education》2016,29(4):536-552

A historical indicator of the quality, validity, and rigor of qualitative research has been the documentation and disclosure of the behind-the-scenes work of the researcher. In this paper, we use what we call methodological data as a tool to complicate the possibility and desirability of such transparency. Specifically, we draw on our disparate attempts to address calls for transparency about methodological processes in our respective dissertation studies in order to examine how novice researchers can explore transparency as a situated, ongoing, and philosophically informed series of decisions about how, when, and if to be transparent about our work. This work contributes to conversations about how qualitative researchers in education can understand, discuss, and teach qualitative inquiry while continuing to push the boundaries of the field.  相似文献   

Does Parental Mind‐Mindedness Account for Cross‐Cultural Differences in Preschoolers’ Theory of Mind?          下载免费PDF全文

Claire Hughes  Rory T. Devine  Zhenlin Wang 《Child development》2018,89(4):1296-1310

This study of 241 parent–child dyads from the United Kingdom (N = 120, M_age = 3.92, SD = 0.53) and Hong Kong (N = 121, M_age = 3.99, SD = 0.50) breaks new ground by adopting a cross‐cultural approach to investigate children's theory of mind and parental mind‐mindedness. Relative to the Hong Kong sample, U.K. children showed superior theory‐of‐mind performance and U.K. parents showed greater levels of mind‐mindedness. Within both cultures parental mind‐mindedness was correlated with theory of mind. Mind‐mindedness also accounted for cultural differences in preschoolers’ theory of mind. We argue that children's family environments might shed light on how culture shapes children's theory of mind.  相似文献

An essay on the implications of university expansion in Kenya     

Rees Hughes  Kilemi Mwiria 《Higher Education》1990,19(2):215-237

Although Kenya may be the most extreme example, expansion of university education is widespread throughout Eastern and Southern Africa. This article examines the irresistible rising tide of populism as it reaches the ivory tower in Kenya. Economic, political, and equity arguments supporting and opposing expansion are outlined. The conclusions, although directed at Kenya, are broadly applicable to those African nations embarking upon a program of tertiary-level growth.  相似文献

Formative Automated Computer Testing (FACT)     

Nicoll Hunt  Janet Hughes  & Glenn Rowe 《British journal of educational technology : journal of the Council for Educational Technology》2002,33(5):525-535

This study describes the context for the development of a tool to formatively assess information technology skills of students. The tool provides a reliable and valid assessment of word processing competency, utilizing automation to apply the test instrument via the Microsoft Office package. Tests can be designed directly by tutors, and delivered via a network. Evaluation of the tests suggests that immediate automated testing is preferred by students compared to a traditional written test. There is evidence that the tool improves the IT skills of its users, whereas a traditional written test has no such beneficial effect.  相似文献

Integrating Northern Ireland: Cross‐group friendships in integrated and mixed schools          下载免费PDF全文

Danielle Blaylock  Joanne Hughes  Ralf Wölfer  Caitlin Donnelly 《British Educational Research Journal》2018,44(4):643-662

While Northern Ireland strives to build a shared society, the current reality is that everyday experiences are still shaped by division along ethno‐religious lines. This is particularly pronounced in the education system, where more than 92% of pupils attend separate schools. Within the predominantly separate education system, however, exists a small collection of schools which cater to a more heterogeneous pupil body and offer the opportunity for young people from both communities to meet and interact, and potentially develop cross‐group friendships. The present study compares the network‐based cross‐group friendships within two such school types; an integrated and a separate post‐primary school. These schools boast a distinct ethos yet they similarly enrol students from Catholic and Protestant backgrounds. Findings reveal that both schools show a high level of interconnection between pupils; however, the integrated school, with an ethos that openly supports social cohesion, shows a greater tendency towards cross‐group interactions and best friendships than those found within the separate school. In line with contact theory, these findings suggest that it may not be enough to simply create opportunities for intergroup contact but that optimal conditions, such as institutional support, may be a prerequisite for positive relationships to flourish. Implications for educational policies designed to promote greater cross‐community contact are discussed.  相似文献   

Doctoral Students' Experiences with Pedagogies of the Home,Pedagogies of Love,and Mentoring in the Academy     

Jennifer Esposito  Taneisha Lee  Kelly Limes-Taylor Henderson  Amber Mason  Anthony Outler  Justina Rodriguez Jackson 《Educational Studies A Journal of the American Educational Studies Association》2017,53(2):155-177

In this article, a group of nontraditional and/or doctoral students of color and our advisor discuss how the advisor-advisee mentoring relationship has positively affected our experiences within academia. The mentoring relationship, cultivated within a group mentoring model, was integral to our acclimation of the hidden culture of our doctoral programs. We elaborate on the history and mentoring model of the group of which we are a part, and follow with a review of the literature on mentoring practices and a discussion of methodology. Finally, through autoethnographic vignettes, each author discusses his/her experience as a non-traditional and/or student of color and how our relationship with the group has provided us with the logistical, emotional, and psychological support needed to progress in and complete our programs.  相似文献
