In many historical and monumental Italian buildings, frescoes or stuccoes of artistic and historical value are present on the lower surface of flat light vaults, made by wooden arches, reeds and plaster. These vaults are often suspended by wooden or metallic ties to the upper bearing structures. When differential settlements of the wooden arches happen (i.e.: due to a bad working of their hangings) cracks appear on these precious surfaces. This paper experimentally and numerically investigates on this issue, pointing out which constructive parameters mainly influence the cracking behaviour of the frescoed or stuccoed lower surface, and thus providing guide lines for designing compatible conservation and retrofitting interventions. 相似文献

This study describes the development of a basic computer-based play pedagogy intervention using a dyscalculia-remedy-oriented approach such as repetition and number orientation manipulation, and the investigation of its effect on children displaying dyscalculia characteristics. This computer play was evaluated in a group of 50 seven-year-old Malaysian children, who were low achievers in mathematics subject and were divided into control and intervention group. The intervention group engaged with the newly developed computer play for an hour per day for five consecutive days, while the control group attended normal classroom learning for the same time period. Overall post-test scores indicated that children from the intervention group performed significantly better than the control group after the five-day intervention period by 57.9%. Number disorientation and arithmetic operation confusion, which are common amongst the children displaying dyscalculia characteristics, were also significantly reduced after the intervention. This implies that the children benefitted from the computer play. 相似文献

This article discusses the views of 25 Icelandic preschool and compulsory school teachers who were interviewed on the role of the outdoor environment in children's learning. The teachers reported not being afraid to take children outside. These teachers valued the learning potentials of the outdoors more than they feared the possible risks. They believed that the outdoors could provide opportunities for (a) enhancing children's play and learning (b) promoting children's health, well-being, and courage, and (c) affecting children's views, knowledge, and actions towards sustainability. 相似文献

The article explores how the Icelandic public school curriculum for early childhood, compulsory and upper secondary school deals with education for sustainable development. As the curriculum does not often mention the term sustainability, a key with which to investigate signs of education for sustainable development in the three curricula was created. The key encourages a holistic view of sustainable development, where economic, environmental and social factors are not treated as separate entities. It was designed to reflect the goals of the United Nations Decade of Education for Sustainable Development (2005–2014) with research on environmental education and education for sustainable development in mind. The key has seven characteristics: values, opinions and emotions about nature and environment; knowledge contributing to a sensible use of nature; welfare and public health; democracy, participation, and action competence; equality and multicultural issues; global awareness; and finally, economic development and future prospects. Using the key, a variety of signs and indicators that provide a space for teachers and schools to deal with issues of sustainable development were identified. 相似文献

This study describes the development of two instruments to investigate the extent to which students are engaged in scientific inquiry. As a result of the instrument development process employed, each finalized instrument consisted of 20-items separated into five categories. Both instruments were found to be internally consistent, with high reliability estimates. Factor analysis showed two factors for each instrument that, while not clustering the items into the five categories, did show item clustering that is consistent with research literature about students’ engagement in inquiry experiences. Based on the analyses completed, the instruments appear to be useful instruments for use in comprehensive assessment packages for assessing the extent to which students are experiencing inquiry in science classrooms. 相似文献

Chlorella vulgaris (CV) has been reported to have antioxidant and anticancer properties. We evaluated the effect of CV on apoptotic regulator protein expression in liver cancer-induced rats. Male Wistar rats (200-250 g) were divided into eight groups: control group (normal diet), CDE group (choline deficient diet supplemented with ethionine in drinking water to induce hepatocarcinogenesis), CV groups with three different doses of CV (50, 150, and 300 mg/kg body weight), and CDE groups treated with different doses of CV (50, 150, and 300 mg/kg body weight). Rats were sacrificed at various weeks and liver tissues were embedded in paraffin blocks for immunohistochemistry studies. CV, at increasing doses, decreased the expression of anti-apoptotic protein, Bcl-2, but increased the expression of pro-apoptotic protein, caspase 8, in CDE rats, which was correlated with decreased hepatoctyes proliferation and increased apoptosis as determined by bromodeoxy-uridine (BrdU) labeling and terminal deoxynucleotidyl transferase mediated dUTP nick-end labeling (TUNEL) assay, respectively. Our study shows that CV has definite chemopreventive effect by inducing apoptosis via decreasing the expression of Bcl-2 and increasing the expression of caspase 8 in hepatocarcinogenesis-induced rats. 相似文献

This study describes the development of an instrument to investigate the extent to which student‐centered actions are occurring in science classrooms. The instrument was developed through the following five stages: (1) student action identification, (2) use of both national and international content experts to establish content validity, (3) refinement of the item pool based on reviewer comments, (4) pilot testing of the instrument, and (5) statistical reliability and item analysis leading to additional refinement and finalization of the instrument. In the field test, the instrument consisted of 26 items separated into four categories originally derived from student‐centered instruction literature and used by the authors to sort student actions in previous research. The SACS was administered across 22 Grade 6–8 classrooms by 22 groups of observers, with a total of 67 SACS ratings completed. The finalized instrument was found to be internally consistent, with acceptable estimates from inter‐rater intraclass correlation reliability coefficients at the p < 0.01 level. After the final stage of development, the SACS instrument consisted of 24 items separated into three categories, which aligned with the factor analysis clustering of the items. Additionally, concurrent validity of the SACS was established with the Reformed Teaching Observation Protocol. Based on the analyses completed, the SACS appears to be a useful instrument for inclusion in comprehensive assessment packages for illuminating the extent to which student‐centered actions are occurring in science classrooms. 相似文献

Career indecision particularly among college and undergraduate students is a concern of counselors and psychologists. This concern has led to numerous research studies related to career indecision and factors that influence it, such as family relationships. In this regard, several studies have reported a significant relationship between career indecision and parental attachment. However, little research has been undertaken on the influence of this factor in regard to career indecision for Iranian students. For this purpose, 158 Iranian freshmen and sophomores who had completed the ‘Career Decision Scale’ (Osipow et al., Journal of Vocational Behavior 9:233–243, 1976) and had been identified as career-undecided, completed the ‘Inventory of Parents and Peer Attachment-Revised’ (Armsden & Greenberg, Journal of Youth and Adolescence 16:427–453, 1987). The results revealed that a significant negative relationship was found between career indecision and attachment to mother, whilst the relationship between career indecision and attachment to father was not significant. However, regression analysis showed parental attachment did not significantly predict career indecision of students. Implications and recommendations for further research are discussed. 相似文献

Students' perceptions of the education environment influence their learning. Ever since the major medical curriculum reform, anatomy education has undergone several changes in terms of its curriculum, teaching modalities, learning resources, and assessment methods. By measuring students' perceptions concerning anatomy education environment, valuable information can be obtained to facilitate improvements in teaching and learning. Hence, it is important to use a valid inventory that specifically measures attributes of the anatomy education environment. In this study, a new 11‐factor, 132‐items Anatomy Education Environment Measurement Inventory (AEEMI) was developed using Delphi technique and was validated in a Malaysian public medical school. The inventory was found to have satisfactory content evidence (scale‐level content validity index [total] = 0.646); good response process evidence (scale‐level face validity index [total] = 0.867); and acceptable to high internal consistency, with the Raykov composite reliability estimates of the six factors are in the range of 0.604–0.876. The best fit model of the AEEMI is achieved with six domains and 25 items (X2 = 415.67, P < 0.001, ChiSq/df = 1.63, RMSEA = 0.045, GFI = 0.905, CFI = 0.937, NFI = 0.854, TLI = 0.926). Hence, AEEMI was proven to have good psychometric properties, and thus could be used to measure the anatomy education environment in Malaysia. A concerted collaboration should be initiated toward developing a valid universal tool that, using the methods outlined in this study, measures the anatomy education environment across different institutions and countries.

It is claimed that by providing a sustainable environment, a university’s research profile can be enhanced. Questions then arise about how universities define sustainability, what criteria are used to judge sustainable quality in research, and how a university can maintain sustainable research quality? This paper places emphasis on sustainable quality of research from the perspective of knowledge sharing. It is argued that effective sharing of knowledge among academics could lead to improved university research performance. It is most important that universities establish credible leadership influences on knowledge sharing. We apply Beer’s Viable System Model to identify those domains of research leadership and knowledge sharing that are necessary for an institution to maintain sustainable quality in research. This paper considers examples of research-knowledge sharing in U.K. research communities, and explores a positive relationship between research leadership and research-knowledge sharing. 相似文献
