Infants make quantity discriminations for substances     

Hespos SJ  Dora B  Rips LJ  Christie S 《Child development》2012,83(2):554-567

Infants can track small groups of solid objects, and infants can respond when these quantities change. But earlier work is equivocal about whether infants can track continuous substances, such as piles of sand. Experiment 1 (N = 88) used a habituation paradigm to show infants can register changes in the size of piles of sand that they see poured from a container when there is a 1-to-4 ratio. Experiment 2 (N = 82) tested whether infants could discriminate a 1-to-2 ratio. The results demonstrate that females could discriminate the difference but males could not. These findings constitute the youngest evidence of successful quantity discriminations for a noncohesive substance and begin to characterize the nature of the representation for noncohesive entities.  相似文献   

Quality assurance in distance education: The challenges to be addressed   总被引：1，自引：0，他引：1  

Antony Stella  A. Gnanam 《Higher Education》2004,47(2):143-160

Integration of technology in all forms ofeducation has narrowed down the gap between theon- and off-campus students and has resulted inthe use of the more broad-based term`distributed learning'. Consequently, distancelearning is seen as a subset of distributedlearning, focusing on students who may beseparated in time and space from their peersand the instructor. The new forms and meaningsit is acquiring, its convergence withtraditional learning and its global impact poseseveral challenges. It has caused a seriousconcern to the governments and the qualityassurance agencies all over the world about thesafety of the national systems, legitimacy ofthe providers, protecting the public from fakeproviders, quality of the offerings etc. thecommon element being `concern for quality'.Many quality assurance agencies have respondedto this need and there is considerable dialogueabout ensuring quality in distance education.Some think that quality assurance practices fordistance education are essentially the same asthose used for traditional education. Othersargue that distance education testsconventional assumptions and hence the presentmechanisms of quality assurance are notadequate to ensure the quality of distanceeducation. This paper highlights the aspects ofdistance education that deviate so markedlyfrom what has been practiced for hundreds ofyears and argues that quality assurance ofdistance education has to be approacheddifferently.  相似文献   

“Women and the environmental are together”: using Participatory Rural Appraisal to examine gendered tensions about the environment     

Cassie F. Quigley  S. Megan Che  Stella Achieng  Sarah Liaram 《Environmental Education Research》2017,23(6):773-796

Environmental education research (EER) rarely includes women’s perspectives. This means that in environmental education research, an entire knowledge source is largely ignored. This study employed a methodology called Participatory Rural Appraisal, a methodology new to the field of EER, of Kenyan teachers from the Maasai Mara region to understand the tensions around environmental views. The purpose of this work was to examine, through the use of a participatory methodology, the conceptions of the environmental of these teachers and to uncover gendered tensions. The analysis included a continuous, thematic review that included the participants during the analysis. The findings included the following themes: Why are people doing what they are doing? Who is or is not acting? How do we move forward? This research documented gendered tensions such as the burdens of responsibility, the power imbalance disadvantaged women feel regarding solving environmental issues, and the blame that is directed at both men and women as a result of these burdens and power imbalances. This methodology provided a way for participants to understand each other’s viewpoints in layered ways, and pointed to gender issues throughout that sometimes caused blame. However, it also helped the participants think about how to work together.  相似文献   

Intergenerational Narratives on Face: A South Asian Indian American Perspective     

Noorie Baig  Stella Ting-Toomey  Tenzin Dorjee 《Journal of International and Intercultural Communication》2014,7(2):127-147

This study investigates the meaning construction of the South Asian Indian term izzat or face in intergenerational contexts. Interpretive thematic analysis revealed six themes. Key findings indicate: (1) for both older and younger South Asian Indian American (SAIA) generations, family izzat is of primary importance; (2) the motif of “respect” is central to both SAIA generations' in their narratives of izzat; (3) both older and younger SAIAs use the concealment-preventative and diversion-restorative facework strategies to save face. These findings uncover intergenerational communication challenges concerning the shifting boundary parameters of izzat in the diasporic Indian community in the US.  相似文献
