Runaway Train: Ex Machina and the Rebel Girls     

Bernard Beck 《Multicultural Perspectives》2016,18(1):29-32

Courtship is a fertile setting for culturally defined strategies. A common form of competition is criticizing the other group for being inadequate mates. Stories about romance between human beings and non-human participants allow such criticism. Movies about men finding mechanical partners are common. Non-human females are seen as more satisfactory than women, especially when women are transforming their roles to be less subservient.  相似文献

Online Schooling in the United States: A Response to Saultz and Fusarelli     

Dennis Beck  Jason LaFrance 《Journal of School Choice》2017,11(1):42-59

In this paper, we discuss some concerns and recommendations of Saultz and Fusarelli (2017), offering nuanced and detailed views of online schooling from a different perspective. This includes addressing challenges regarding online learning such as fluctuating enrollments, financial concerns, quality assurance, and accountability. In addition, we propose recommendations related to funding, better quality data, and oversight and monitoring. We conclude with a short discussion of the need for differentiated research for specific online learning contexts.  相似文献   

Almost thinking counterfactually: children's understanding of close counterfactuals     

Beck SR  Guthrie C 《Child development》2011,82(4):1189-1198

Saying something "almost happened" indicates that one is considering a close counterfactual world. Previous evidence suggested that children start to consider these close counterfactuals at around 2 years of age (P. L. Harris, 1997), substantially earlier than they pass other tests of counterfactual thinking. However, this success appears to result from false positives. In Experiment 1 (N = 41), 3- and 4-year-olds could identify a character who almost completed an action when the comparison did not complete it. However, in Experiments 1 and 2 (N = 98), children performed poorly when the comparison character completed the action. In Experiment 3 (N = 28), 5- and 6-year-olds consistently passed the task, indicating that they made appropriate counterfactual interpretations of the "almost" statements. This understanding of close counterfactuals proved more difficult than standard counterfactuals.  相似文献   

Using digital images of the zebra finch song system as a tool to teach organizational effects of steroid hormones: a free downloadable module     

Grisham W  Schottler NA  McCauley LM  Pham AP  Ruiz ML  Fong MC  Cui X 《CBE life sciences education》2011,10(2):222-230

Zebra finch song behavior is sexually dimorphic: males sing and females do not. The neural system underlying this behavior is sexually dimorphic, and this sex difference is easy to quantify. During development, the zebra finch song system can be altered by steroid hormones, specifically estradiol, which actually masculinizes it. Because of the ease of quantification and experimental manipulation, the zebra finch song system has great potential for use in undergraduate labs. Unfortunately, the underlying costs prohibit use of this system in undergraduate labs. Further, the time required to perform a developmental study renders such undertakings unrealistic within a single academic term. We have overcome these barriers by creating digital tools, including an image library of song nuclei from zebra finch brains. Students using this library replicate and extend a published experiment examining the dose of estradiol required to masculinize the female zebra finch brain. We have used this library for several terms, and students not only obtain significant experimental results but also make gains in understanding content, experimental controls, and inferential statistics (analysis of variance and post hoc tests). We have provided free access to these digital tools at the following website: http://mdcune.psych.ucla.edu/modules/birdsong.  相似文献   

Promoting Inquiry-Based Teaching in Laboratory Courses: Are We Meeting the Grade?     

Christopher Beck  Amy Butler  Karen Burke da Silva 《CBE life sciences education》2014,13(3):444-452

Over the past decade, repeated calls have been made to incorporate more active teaching and learning in undergraduate biology courses. The emphasis on inquiry-based teaching is especially important in laboratory courses, as these are the courses in which students are applying the process of science. To determine the current state of research on inquiry-based teaching in undergraduate biology laboratory courses, we reviewed the recent published literature on inquiry-based exercises. The majority of studies in our data set were in the subdisciplines of biochemistry, cell biology, developmental biology, genetics, and molecular biology. In addition, most exercises were guided inquiry, rather than open ended or research based. Almost 75% of the studies included assessment data, with two-thirds of these studies including multiple types of assessment data. However, few exercises were assessed in multiple courses or at multiple institutions. Furthermore, assessments were rarely based on published instruments. Although the results of the studies in our data set show a positive effect of inquiry-based teaching in biology laboratory courses on student learning gains, research that uses the same instrument across a range of courses and institutions is needed to determine whether these results can be generalized.  相似文献

Dopaminerge Modulation striataler Plastizität     

Frieder Beck  Klaus Blischke  Birgit Abler 《Sportwissenschaft》2012,42(4):271-279

This article attempts to outline the neuronal foundations of movement automatization. In particular, it is shown that an increase in automaticity corresponds to processes of synaptic plasticity in the corticostriatal and corticocortical system. This mechanism is supposed to induce changes in the neuronal representations of the respective skill. Furthermore, the role of phasic dopamine release will be discussed with respect to its modulating effect on processes of plasticity.  相似文献   

Cluster-K: Network topology for searching replicated data in p2p systems     

Tayo Obafemi-Ajayi  Sanjiv Kapoor  Ophir Frieder 《Information processing & management》2012

This paper proposes a new scheme for ensuring data consistency in unstructured p2p networks where peers can subscribe to multiple content types (identified by labels) and are rapidly informed of content updates. The idea is based on using a static tree structure, the Cluster-K⁺ tree, that maintains most of the structural information about peers and labels. A label denotes a set of replicated or co-related data in the network. The Cluster-K⁺ tree provides efficient retrieval, addition, deletion and consistent updates of labels. Our proposed structure guarantees a short response search time of O(H + K), where H denotes the height of the tree and K the degree of an internal tree node. We present theoretical analytic bounds for the worst-case performance. To verify the bounds, we also present experimental results obtained from a network simulation. The results demonstrate that the actual performance of our system is significantly better than the theoretical bounds.  相似文献
