Predictors of academic success in medical school

This study was designed to determine the predictive validity of selected admissions variables used by the University of Kentucky College of Medicine. Data for the study were collected from 586 students admitted to the M.D. program from 1961 to 1968. These students were categorized into one of three groups (Successful [SUCC], Successful with Extended Study [SWES], and Lost to Medicine [LTM]) based upon their performance in medical school. A two-way analysis of variance and the use of a post hoc Scheffé method of multiple comparisons indicated significant differences between the SUCC group and the combined SWES and LTM groups. Therefore, the data revealed the predictive ability of two admissions variables and suggested the need for additional research into the subjective variables used in the admissions process.     

An exploratory investigation of the effect of working in an environmentally themed facility on the conservation‐related knowledge,attitudes and behavior of staff

In the past decade, we have seen an increased focus on measuring the impact of zoos, aquariums, and other free‐choice learning environments on the conservation‐related knowledge, attitudes and behavior of the visiting public. However, no such studies have been conducted on the impact of such environments on the staff working in these facilities – the very staff that in turn interact with the public on a daily basis. Clearly these interactions are recognized as being important; for example, the thousands of staff employed by Disney’s Animal Kingdom are regularly provided with conservation‐related training – both formal, in‐class experiences, as well as more informal experiences with animals; these are a mixture of compulsory and freely chosen experiences. An exploratory qualitative study was conducted to investigate the impact of working at Disney’s Animal Kingdom on staff knowledge, attitudes, and behavior related to animals and their conservation. The resulting findings offer preliminary evidence that working in an environmentally themed setting has a positive impact on all of these variables, and that particular experiences – notably experiences in back‐of‐house animal holding areas and with animal staff – are key. These findings suggest that further investigation into the impact of working in such learning settings could be fruitful in understanding the role that the work place plays in supporting the free‐choice learning of staff. This is important both from the perspective of the staff themselves, and in relation to the impact that these individuals may have on visitors to free‐choice learning settings.     

Discourses and Subjectivities of the Gendered Teacher

In this study, the authors ask the question, 'What does it mean to wear the labels "teacher" and "female"?' Eighteen Master of Arts in Teaching students volunteered to participate in a Gender Issues Seminar at a large US public state university. Their language, recorded through audio-recordings, response journals, and autobiographical webs become the basis for analysis. Applying post-structural feminist theory, the authors identify powerful discourses determining what it means to be 'female' and 'teacher.' The study illustrates how the discourse of teaching as acceptable women's work and the discourse of patriarchy work upon the subjectivity of women as they struggle with what it means to be teacher/woman. The authors then partially deconstruct these discourses, considering implications for teacher educators.     

A New Marketing Paradigm for Electronic Commerce

The World Wide Web possesses unique characteristics that distinguish it in important ways from traditional commercial communications environments. Because the Web presents a fundamentally different environment for marketing activities than traditional media, conventional marketing activities are becoming transformed, as they are often difficult to implement in their present form. In this article, we discuss the idea that these changes portend an evolution in the 'marketing concept' and argue that in order for marketing efforts to be successful in this new medium, a new business paradigm is required. In this new approach, the marketing function must be reconstructed to facilitate electronic commerce in the emerging electronic society underlying the Web.     

Teachers' Views about What to do about Sustainable Development

In its various guises the political and economic implications of the spectrum of ideas labelled ‘sustainable development’ have been widely discussed in the media. This research engaged secondary school teachers in the debate concerning the implications for education of the concept of sustainable development. Underpinning this pilot research project is the assumption that teachers, as generally informed citizens, have been sensitised to some of the issues raised in the public domain. Teachers in both the USA and Scotland were interviewed to ascertain the extent to which they had begun to make connections between what they have heard and read informally about sustainable development and their responsibilities as teachers. The objective of this research was to determine the impact of this informal ‘environmental’ education on teaching practice.     

Serial pattern learning of temporal intervals

The problem was to determine how rats adjust the times of their lever responses to repeating sequences of interfood intervals. In Experiment 1, rats were trained on an interval schedule of reinforcement with a 12-element Fleshler-Hoffman series with a mean of 60 sec; the order was as follows: ascending, random with repetition, random with replacement, random without replacement. In Experiment 2, rats were trained with a 10-element ascending or descending series (from 2⁰ to 2⁹ sec), and in a ramp procedure in which these intervals increased and then decreased repeatedly. In the ascending, descending, and ramp conditions (but not in the random conditions), postreinforcement pause (PRP) was a function of the interval. PRP was most highly correlated with an interval later in the series. Theories of conditioning and timing based on the averaging of past experience must be modified to account for such anticipatory behavior.     

Behavior of Infants with Iron-Deficiency Anemia

This study tested the hypothesis that infants with iron-deficiency anemia show behaviors, such as increased proximity to caregivers, increased wariness or hesitance, and decreased activity, that could contribute to “functional isolation.” The behavior of 52 Costa Rican 12- to 23-month-old infants with iron-deficiency anemia was contrasted with that of 139 comparison group infants with better iron status during free play and mental and motor testing and in the home. Infants with iron-deficiency anemia maintained closer contact with caregivers; showed less pleasure and delight; were more wary, hesitant, and easily tired; made fewer attempts at test items; were less attentive to instructions and demonstrations; and were less playful. Adult behavior also differed. The results indicate that iron-deficiency anemia in infancy is associated with alterations in affect and activity, suggesting that functional isolation is a useful framework for understanding poorer developmental outcome in iron-deficiency anemia, the world's most common single nutrient deficiency.     

Building Mind, Brain, and Education Connections: The View From the Upper Valley

ABSTRACT— This article describes the efforts of a small group of educators and researchers to build a model for making connections across mind, brain, and education. With a common goal of sharing, strengthening, and building useable knowledge about child and adolescent learning and development, we focused on questions of mutual interest to educators and researchers. We describe our efforts to develop a common vocabulary and language and to create opportunities for dialogue and discussion, including classes and talks for in-service and preservice teachers, research laboratories open to in-service and preservice teachers, local conferences that provided a context for educator and researcher interactions, and researcher outreach in the local education community at the administrative, classroom, and student levels. These activities represent concrete mechanisms by which links might be forged between educators and researchers within the context of Mind, Brain, and Education.     

蒲公英的启示

我记得小时候常常送蒲公英给我母亲。尽管花茎粘糊糊的,而且每当草坪上出现了这些花儿时,父母总会骂上几句,但这些都没有关系。我觉得它们美极了!这些花朵总是春风吹又生。父亲和兄弟们至少每周用一次割草机把它们割干净,却还是拿这些坚韧的小家伙们没办法。
