This study is an attempt to contribute to the growing body of knowledge about students' conceptions and views concerning environmental and natural resource issues. Answers have been sought to the following questions: “How do Swedish students in grade 9 (15–16 years old) and grade 12 (18–19 years old) explain the greenhouse effect?”, “How do they think reduction of CO2 emission would affect society?” and “How do they explain that the depletion of the ozone layer is a problem?” The method chosen to answer these questions was to give students written tasks of the open‐ended type. Five models of the greenhouse effect appear among the answers, all more or less incomplete, but nevertheless with potential for development. The students' responses also indicate that they do not fully understand what fundamental societal changes would occur as a result of a drastic reduction in CO2 emission. On the other hand, they are rather well informed about how injurious depletion of the ozone layer is to humans. The findings are discussed, including implications for teaching. © 2000 John Wiley & Sons, Inc. J Res Sci Teach 37: 1096–1111, 2000 相似文献

Since Freud's era, women have been counseling and psychotherapy's largest consumers. White Freud talked and wrote almost exclusively about men, his patients were primarily women. This practice of treating women as patients, while perceiving men as the prevailing standard for percept and practice has resulted in the largely androcentric or mate-determined psychology of human behavior which we have today (Denmark, 1980; Hare-Mustin, 1983).A number of studies commencing with the Broverman's work in the 1970(s) has demonstrated that psychotherapists, for the most part, share the same sex role biases toward women as the rest of society (Broverman et al., 1970; Fabrikant, 1973, 1974; Nickerson, 1978; Orlinsky & Howard, 1980). Most disconcerting, however, is a recent extensive replication of the Brovermans' study (O'Malley & Richardson, 1985), using 249 counselors, which found that they still described males and females in stereotypic ways, though they did attribute some female designated traits to healthy adults.The evidence regarding the measured effects of therapists' attitudes, whether reportedly biased or gender-fair, however, is mixed in nature and replete with methodological problems (Maffeo, 1979; Marachek & Johnson, 1980; Orlinsky & Howard, 1980; Smith, 1980; Whiteley, 1979); as is the evidence for effectiveness of therapy generally (Garfield, 1981). Some have argued that a counselor's values and expectations do not matter, as long as she or he is aware and does not impose them (Smith, 1980; Whiteley, 1979). It would seem equally probable, based on other evidence that choice of therapeutic goals and processes can be influenced by the therapist's expectations (Brovermans et al., 1970; Nickerson, 1978; O'Malley & Richardson, 1985).The crucial point is that in a sexist society (Such as the United States), it is improbable that anyone without special non-sexist, gender-fair training can adequately aid women in exercising their independence and selecting their goals. Hence, a format is presented for insuring the dream of gender-fair counseling through the inclusion of appropriate training experiences and materials. 相似文献

Objectives: For general practitioners (GPs), an important obstacle to practising evidence‐based medicine is lack of time. An evidence‐based answering service was developed that took over searching and appraisal of medical evidence from the GPs. GPs sent in questions, and the informationist formulated the answers. Our objectives were to find out if such an evidence‐based answering service was feasible, including assessing the effect of the answers on GPs and their patients, as reported by the GPs. Methods: After attending a workshop on building well‐formulated questions from daily practice, the GPs sent in questions to the informationist. The literature was searched, the relevant information was appraised, and the answers to the questions were formulated. With a questionnaire, the effect of the answers on the GP and the patient was assessed, as well as the perceived barriers to implementing the answers. Results: From 26 GPs, 61 questions were received. For 12% of questions, information was found with the highest evidence level, while for 36%, no information was found. However, for 89% of the questions for which no information could be found, the answer ‘no information found’ did have an effect on the GP concerned. In total, 81% of all the answers had an effect on the GP, and, according to the GP, 52% had an effect on the patient. Few barriers to implementing the evidence were perceived. Most of the answers were found in Pubmed/Medline, the Cochrane Library and Embase. Conclusions: This study indicates that an evidence‐based answering service can have an impact on GPs and their patients. Librarians can provide an evidence‐based answering service for GPs and their patients. The evidence‐based answering service for GPs in this study had an impact on 81% of the GPs and on 52% of their patients. Although for one‐third of the questions no evidence‐based answer was found, this message in itself had an impact on 89% of the GPs. An informationist as mediator between medical information and doctors can save doctors’ time. 相似文献

This article describes a small‐scale study exploring the perspectives of five undergraduate students with dyslexia. Semi‐structured interviews were conducted in two universities in the UK. The interviews explored participants’ perceptions of their dyslexia label and how it had affected their academic success. The aim of the research was to identify facilitating factors that supported participants with dyslexia during their education. The following themes were identified: age of dyslexia identification, family support, dyslexic identity, self‐advocacy skills and learning resources. The study makes a case for an intervention for children and young people (CYP) with dyslexia that, in addition to remedial literacy support, explores self‐advocacy, thinking and study skills and facilitates positive academic self‐concepts. Future research could evaluate such an intervention for its effectiveness on CYP's social emotional well‐being and literacy skills. 相似文献

Although many environmental and science educators have explored students’ conceptual understandings, misconceptions, and knowledge of the greenhouse effect, global warming, and climate change, few have investigated the ways students conceptualize climate as a system or how components of the system influence climate. Therefore, the purpose of this study was to begin the process of understanding how US students conceptualize a climate system. A total of 42 seventh grade students (ages 12–13) from the Midwest completed an open-response task. From the inductive analysis of student written responses, 22 codes emerged that reflected students’ conceptions of the climate system. From these codes, three path diagrams were constructed that illustrate these students’ conceptions about how a climate system influences climate and how greenhouse gases and global warming impact the climate system. A generalized model of students’ conception of a climate system was generated. Students in this study conceptualized a climate system in a unidirectional, linear, cause and effect relationship that emphasized the atmospheric component of the climate system. 相似文献

While there has been research conducted on public views about ethical and social aspects of the National DNA Database (NDNAD), there is little which focuses on views of young people, in particular those whose details are held on the NDNAD. We describe an engagement activity developed in South Wales to engage young offenders with ethical and social issues surrounding the NDNAD--a Mock Trial--and how we facilitated the presentation of their views to policy makers. We discuss the successes and challenges we encountered with engaging young offenders, decisions that the young people reached about possible future policies for the NDNAD at the Mock Trial, and their contribution to the decision-making process. 相似文献

The medical, agricultural and biotechnological importance of the primitive eukaryotic microorganisms, the Fungi was recognized
way back in 1920. Among various groups of fungi, the Aspergillus species are studied in great detail using advances in genomics and proteomics to unravel biological and molecular mechanisms
in these fungi. Aspergillus fumigatus, Aspergillus flavus, Aspergillus niger, Aspergillus parasiticus, Aspergillus nidulans and Aspergillus terreus are some of the important species relevant to human, agricultural and biotechnological applications. The potential of Aspergillus species to produce highly diversified complex biomolecules such as multifunctional proteins (allergens, antigens, enzymes)
and polyketides is fascinating and demands greater insight into the understanding of these fungal species for application
to human health. Recently a regulator gene for secondary metabolites, LaeA has been identified. Gene mining based on LaeA
has facilitated new metabolites with antimicrobial activity such as emericellamides and antitumor activity such as terrequinone
A from A. nidulans. Immunoproteomic approach was reported for identification of few novel allergens for A. fumigatus. In this context, the review is focused on recent developments in allergens, antigens, structural and functional diversity
of the polyketide synthases that produce polyketides of pharmaceutical and biological importance. Possible antifungal drug
targets for development of effective antifungal drugs and new strategies for development of molecular diagnostics are considered. 相似文献
