The inheritance of behavioral wildness in house mice (Mus musculus L.)     

Roy H. Smith  James L. Connor 《Learning & behavior》1974,2(4):249-256

Fourteen behavioral measures were ranked according to their ability to differentiate performances of a wild population of mice from three domestic inbred strains. These “wildness” rankings were then analyzed for their ability to predict genetic and Genotype by Environment interactions. Genetic parameters were derived from analysis of three inbred domestic strains and their three hybrid crosses via the diallel technique of genetic analysis. Genotype by Environment interactions were assessed both as mean differences in stock performances resulting from rearing in a laboratory vs naturalistic environment and as differences in environmental variability within stock genotypes. Behavioral characters ranking high on “wildness” failed to demonstrate any unitary pattern of Genotype by Environment interactions. The diallel genetic analysis revealed many examples of additive variation but relatively few examples of dominant variation. An extremely wide range of interactions occurred between genotype and rearing environments, with “wildness” and “developmental homeostasis” concepts both failing to account for all the observed interactions.  相似文献

Relationship between foot strike pattern,running speed,and footwear condition in recreational distance runners

Compared to competitive runners, recreational runners appear to be more prone to injuries, which have been associated with foot strike patterns. Surprisingly, only few studies had examined the foot strike patterns outside laboratories. Therefore, this study compared the foot strike patterns in recreational runners at outdoor tracks with previously reported data. We also investigated the relationship between foot strike pattern, speed, and footwear in this cohort. Among 434 recreational runners analysed, 89.6% of them landed with rearfoot strike (RFS). Only 6.9 and 3.5% landed with midfoot and forefoot, respectively. A significant shift towards non-RFS was observed in our cohort, when compared with previously reported data. When speed increased by 1 m/s, the odds of having forefoot strike and midfoot strike relative to RFS increased by 2.3 times and 2.6 times, respectively. Runners were 9.2 times more likely to run with a forefoot strike in minimalists compared to regular running shoes, although 70% of runners in minimalists continued to use a RFS. These findings suggest that foot strike pattern may differ across running conditions and runners should consider these factors in order to mitigate potential injury.  相似文献   

Borders and Intersections of Possibility: Multilingual Repertoires of Refugee Families in the Southwest U.S.     

Laura A. Roy 《Multicultural Perspectives》2015,17(2):61-68

This study examines the linguistic and cultural intersections of recently arrived Somali Bantu refugee students in South Texas through the lens of border theory. The use of Spanish in the homes of refugee families is explored in addition to ways in which an educator used testimonios to honor students’ migration experiences. Findings show how specific approaches used in schools that affirm both the receiving communities’ and the new arrivals' local knowledge can have a lasting impact on literacy acquisition and resettlement experiences. Findings from this study also illuminate the potential impact of educators who develop a critical, inquiry stance by embedding multiple entry points for students to cross social, cultural, linguistic, and curricular borders in school.  相似文献

Self-recording in kindergarten: A study in naturalistic evaluation     

Patti Studwell  Roy Moxley 《Psychology in the schools》1984,21(4):450-456

When kindergarten children began to self-record their own progress in skills targeted across the curriculum, there was a distinct increase in their rate of achieving these skills. It is argued that this has significant implications for a comprehensive, naturalistic evaluation in the classroom, with many benefits and few costs.  相似文献   

Supporting teachers in making innovative changes in the use of computer‐aided practical work to support concept development in physics education     

Roy Barton 《International Journal of Science Education》2013,35(3):345-365

There continues to be a gulf between what have been identified from the literature as the potential benefits of using computer‐aided practical work and the difficulties of realizing them as reported by practising teachers, even from those who are committed to the use of Information and Communication Technology (ICT). This article reports on a pilot study that aimed to explore ways in which teachers could be supported as they explore the extent to which this approach could enhance the development of pupils’ understanding of physics concepts. The study was based on a collaborative partnership between a researcher and a classroom teacher. The indications are that there is the potential for considerable benefits from such an approach, with the need for further development of materials and teaching methods being identified.  相似文献

Abstract

The claim that students should determine their own curricula is examined. If granted, primacy would be given to the autonomy and self‐ascribed interests of the students. The case for student autonomy is discussed in the context of the theory of philosophical anarchism. The anarchist dichotomy of autonomy and authority is criticised. A brief examination of Kant's account of autonomy leads to a rejection of the strong individualism that characterises that dichotomy. It is argued that the curriculum should be the outcome of the shared autonomy of students and teachers; such would serve the interests of students by maximising the autonomy of all. The curriculum would meet the interests of all students, but would not, indeed could not, represent the self‐ascribed interests of each individual.  相似文献
