Issues of sustainability are complex and often steeped with ethical and political questions without predefined or general answers. This paper deals with how secondary and upper secondary teachers discuss these complex issues, by analysing their aims for Education for Sustainable Development. With inspiration from discourse theory, their articulations about students as political subjects are analysed. Critical thinking emerged as a nodal point in teachers’ discussions. In this study, critical thinking is articulated as having various qualitative meanings related to different epistemological views. On one hand, critical thinking is articulated to invite room for subjectification; but on the other hand, room for subjectification is challenged when critical thinking is articulated through the educational aims of qualification and socialisation. A consequence of changing epistemological view might be that political and ethical issues take a back seat. 相似文献

A student's expectation for a positive outcome for their future career development is referred to as career optimism. Career Services, a common university department, utilizes the social cognitive career theory (SCCT) to understand how students form career interests and make educational and vocational choices. Then Career Services can assist students in finding a career that matches their interests. We hypothesize that students' perception of the assistance provided by the Career Services department when the SCCT is applied, impacts the student's career optimism. In addition, we hypothesize, and results support, that different factors, such as a student's chosen major, impact student perception of Career Services and career optimism. 相似文献

The study examined the moderating role of children's affect-biased attention to angry, fearful, and sad adult faces in the link between interparental conflict and children's distinct forms of involvement. Participants included 243 preschool children (Mage = 4.60 years, 56% female) and their parents from racially (48% African American, 43% White) and socioeconomically (median annual household income = $36,000) diverse backgrounds. Data collection took place in the Northeastern United States (2010–2014). Utilizing a multi-method, multi-informant, longitudinal design, attention away from anger selectively amplified the link between interparental conflict and children's subsequent coercive involvement (β = −.15). Greater attention to fear potentiated the pathway between interparental conflict and children's later cautious (β = .14) and caregiving involvement (β = .15). Findings are interpreted in the context of environmental sensitivity models. 相似文献

In laboratory medicine, several studies have described the most frequent errors in the different phases of the total testing process, and a large proportion of these errors occur in the pre-analytical phase. Schemes for registration of errors and subsequent feedback to the participants have been conducted for decades concerning the analytical phase by External Quality Assessment (EQA) organizations operating in most countries. The aim of the paper is to present an overview of different types of EQA schemes for the pre-analytical phase, and give examples of some existing schemes. So far, very few EQA organizations have focused on the pre-analytical phase, and most EQA organizations do not offer pre-analytical EQA schemes (EQAS). It is more difficult to perform and standardize pre-analytical EQAS and also, accreditation bodies do not ask the laboratories for results from such schemes. However, some ongoing EQA programs for the pre-analytical phase do exist, and some examples are given in this paper. The methods used can be divided into three different types; collecting information about pre-analytical laboratory procedures, circulating real samples to collect information about interferences that might affect the measurement procedure, or register actual laboratory errors and relate these to quality indicators. These three types have different focus and different challenges regarding implementation, and a combination of the three is probably necessary to be able to detect and monitor the wide range of errors occurring in the pre-analytical phase. 相似文献

Bioluminescence resonance energy transfer (BRET) is a form of Förster resonance energy transfer. BRET has been shown to support lower limits of detection than fluorescence resonance energy transfer (FRET) but, unlike FRET, has not been widely implemented on microfluidic devices for bioanalytical sensing. We recently reported a microscope-based microfluidic system for BRET-based biosensing, using a hybrid, high quantum-efficiency, form of BRET chemistry. This paper reports the first optical fiber-based system for BRET detection on a microfluidic chip, capable of quantifying photon emissions from the low quantum-efficiency BRET2 system. We investigated the effects of varying core diameter and numerical aperture of optical fibers, as well as varying microfluidic channel design and measurement conditions. We optimized the set-up in order to maximize photon counts and minimize the response time. The optimized conditions supported measurement of thrombin activity, with a limit of detection of 20 pM, which is lower than the microscope-based system and more than 20 times lower than concentrations reported to occur in plasma clots. 相似文献

The article examines the history of parental education in Cyprus from its beginnings in the 1960s until the present day, in the wider context of Cypriot history and education. It considers the three main forums of parental education in the country, the Pancyprian School for Parents, the Adult Education Centres of the Ministry of Education and Culture and the University of Cyprus, which roughly coincide with the past, the present and the future of parental education on the island. The article comments on the development of the teaching philosophy and approach in the area of parental education, namely from a passive teacher centred traditional didactic model to a more dynamic participatory partnership. 相似文献

Aristotle's concept of ethos is primarily one based on civic duty, and as such loses its specificity when extended to the scientific forum. By adapting Aristotle's traditional concept of ethos to contemporary social norms of science, a link can be established between classical theory and contemporary practice. In this essay, I use Robert Merton's theory of the normative conditions of science to perform a meta‐critique of the use of ethos in four case studies. This meta‐analysis reveals the dual structure of ethos as reflected in a surface structure of style and a deep structure of argument. 相似文献
