All cells respond to chemical stimuli and the nature of the mechanisms involved is thus very important. This article reviews the response of one of the simplest organisms, Escherichia coli, to chemical stimulation, as evidenced by the effect on flagellar movements. Even this elementary sensory-response system involves almost 50 gene products. 相似文献

This study analyzed the satisfaction and compliance of 91 in‐clinic patients based on their affiliation with a Health Delivery System and the patient's self‐efficacy. Several significant results emerged from the study. A patient's Health Delivery System and the patient's self‐efficacy interact to predict communication satisfaction. It was also discovered that a patient's Heath Delivery System and the patient's self‐efficacy interact to predict compliance. Implications and limitations of this research are discussed. 相似文献

The present study investigates the characteristics which differentiate between first-year university students who maintain
their high school averages (Maintainers: n = 165) and those whose averages decrease at least one letter grade (Decliners: n = 435). The 600 students entered first year at one of six Canadian Universities, which varied in size and ethnic diversity.
Data were collected in August, prior to the start of school, and in November of first year. Multivariate analyses indicated
significant group differences between Maintainers and Decliners on familial variables (gender, fathers’ education level, but
not family income, parental reciprocity, parental support or immigrant/generational status), psychological well-being (perceived
stress in August and November, and November depression, self-esteem and health), and university adjustment (university plans,
transition perception, time management and university adaptation). The current study addresses a gap in the existing academic
achievement literature, while providing practical information to students, parents, and educators involved in the transition
to university. 相似文献

This paper presents a theoretical basis for cultivating engineering education as a complex system that will prepare students to think critically and make decisions with regard to poorly understood, ill-structured issues. Integral to this theoretical basis is a solution space construct developed and presented as a benchmark for evaluating problem-solving orientations that emerge within students’ thinking as they progress through an engineering curriculum. It is proposed that the traditional engineering education model, while analytically rigorous, is characterised by properties that, although necessary, are insufficient for preparing students to address complex issues of the twenty-first century. A Synthesis and Design Studio model for engineering education is proposed, which maintains the necessary rigor of analysis within a uniquely complex yet sufficiently structured learning environment. 相似文献

Science educators have the common goal of helping students develop scientific literacy, including understanding of the nature of science (NOS). University faculties are challenged with the need to develop informed NOS views in several major student subpopulations, including science majors and nonscience majors. Research into NOS views of undergraduates, particularly science majors, has been limited. In this study, NOS views of undergraduates in introductory environmental science and upper-level animal behavior courses were measured using Likert items and open-ended prompts. Analysis revealed similarities in students'' views between the two courses; both populations held a mix of naïve, transitional, and moderately informed views. Comparison of pre- and postcourse mean scores revealed significant changes in NOS views only in select aspects of NOS. Student scores on sections addressing six aspects of NOS were significantly different in most cases, showing notably uninformed views of the distinctions between scientific theories and laws. Evidence-based insight into student NOS views can aid in reforming undergraduate science courses and will add to faculty and researcher understanding of the impressions of science held by undergraduates, helping educators improve scientific literacy in future scientists and diverse college graduates. 相似文献

This study examined the nature of students’ out-of-class involvements with a view to identifying the kinds of involvement
that are most conducive to positive adjustment to university. Students from five Canadian universities completed questionnaires
in November of their first-year at university assessing the quality of their out-of-class involvements and the extent to which
such activities were structured (i.e., supervised, performed regularly, had a goal or purpose). Measures of adjustment to
university were administered in November and March of their first-year. Results indicated that the amount of structure present
in out-of-class activities was positively related to university adjustment. Activity quality was found to mediate the relationship
between activity structure and university adjustment; it seems that activities that are highly structured are related to more
positive outcomes because they tend to provide participants with a high-quality experience. Results are discussed in terms
of the transition to university, and first-year transition intervention programs. 相似文献

As shared services organizations (SSO) become more popular as a service management and delivery option in government, properly defining and setting up the governance structure continues to be a key success factor. This paper explores the options and issues to consider when selecting and implementing shared services governance including topics such as oversight, accountability, culture, management of resources, and of day-to-day operations. Shared services organizations are increasingly common in private sector companies and the particular challenges involved in the governance of an SSO in a public service context are highlighted and discussed. 相似文献

In 1933, the Prussian Academy of Sciences and Humanities was an exclusive learned society, out of touch with modern methods and funding, which had also failed to re-establish itself as a centre of research. During the Nazi regime, it was at best peripherally involved in the restructuring of German academia. While some of its members played a political role, the Academy itself retained its status as a learned society, even an academic club. This helped make possible its subsequent adaptation to the new political order in post-war Germany. 相似文献

The objectives of this study were to (a) identify the major tenets of a preservice secondary science education program as expressed by science education faculty, (b) identify knowledge structures that beginning secondary science teachers have constructed about the teaching and learning of science, and (c) identify the correlatives that exist between the first two objectives. The study was grounded in the postulates of teacher cognition in that teachers construct their own schema from their experiences in order to comprehend, plan for, and respond to the dynamics of their classroom. This qualitative study consisted of interviews and observations of beginning science teachers, interviews with science education faculty, and an analysis of the course syllabi of that faculty. Methods of single and cross-case analytic induction were combined to analyze the data. Based on the data, it may be concluded that aspects of the program, such as student-centered learning, cooperative learning, general pedagogical knowledge, and pedagogical content knowledge, were adopted into the schema of the beginning teachers; the degree of adoption appeared to be linked to the individual's most significant learning experiences and the constraints of the school situation. © 1997 John Wiley & Sons, Inc.
