Artistic patination is a traditional colouring technique for metal sculpture, employed by artists in ancient and modern times for aesthetic purposes. Today, knowledge of the artistic value and the chemistry of this superficial chromatic layer, called ‘artistic patina’, can be successfully acquired through a close collaboration between living artists, foundry artisans, and scientists. Starting from several interviews with the Italian artist Nado Canuti and foundry artisans, specific information was gathered about patination methods and the artist’s attitude towards materials restoration. Afterwards, the patinas most used by Canuti were reproduced to study their nature before any ageing or degradation. Their chromatic values, morphologies, and compositions were studied employing a range of techniques such as colour measurements, scanning electron microscopy with energy dispersive X-ray spectroscopy, and micro-Raman spectroscopy. The collected data revealed the formation of main compounds (cuprite, cassiterite, rouaite, chalcocite, isocubanite, and ferroxyhite) and additional compounds (atacamite and CN-containing compound). The scientific results, as well as the artist’s statements concerning the patinas’ significance, maintenance, and conservation, will contribute towards the future care and preservation of Canuti’s sculptures. 相似文献

ABSTRACTAction research is an important methodology that promotes participatory processes in the community, enhancing community networks and empowering people to define their own health and generate actions. Here, we performed a systematic review using the Scopus, Web of Science (WoS) and SciELO databases to identify the studies carried out on health in Latin America under the category ‘Action Research’. The search terms used were ‘Action Research’, ‘Health’ and ‘Latin America’. We identified the following three areas of particular relevance: (a) action research is a necessary strategy to make health actions more efficient by adapting institutional actions to specific realities; (b) action research can increase the visibility of excluded groups and demonstrates the importance of being heard; and (c) action research can promote community empowerment by considering community members as knowledge agents who can transform their own reality. We report that action research processes which highlight the emancipatory and democratizing potential of community participation are subject to controversy regarding the production of and access to knowledge and the issues related to health. However, action research is not usually used in the development and implementation of institutional health interventions. 相似文献

In 2008 Grand Valley State University Libraries began a large weeding project in the automated retrieval system (ARS) at its Steelcase Library. An estimated 19,000 volumes were to be removed from the ARS. A systematic weeding of the ARS had never been undertaken and it presented a number of logistical challenges. This article discusses the process that was devised for this large weeding project. 相似文献

Young people with English as an Additional Language/Dialect backgrounds are often identified in public health messages and popular media as ‘bodies at risk’ because they do not conform to the health regimens of contemporary Western societies. With increasing numbers of Chinese students in Australian schools, it is necessary to advance teachers' understandings of the ways in which these young people negotiate notions of ‘health’ and ‘(un)healthy bodies’. This paper explores the ways in which young Chinese Australians' understand health and (un)healthy bodies. The data upon which this paper focuses were drawn from a larger scale study underpinned by critical, interpretive, ethnographic methods. The participants in this study were 12 young Chinese Australians, aged 10–15 years, from two schools. Photographs of a variety of bodies were sourced from popular magazines and used as a means of interview elicitation. The young people were invited to comment on the photographs and discuss what ‘health’ and the notion of a ‘(un)healthy body’ meant to them. Foucault's concepts of discursive practice and normalisation are used alongside Chinese concepts of holistic paradigms and Wen–Wu to unpack the young people's subjectivities on health and (un)healthy bodies. The findings invite us to move beyond Western subjectivities of health and (un)healthy bodies and highlight the multidimensional and diverse perspectives espoused by some of the young Chinese Australians in this study. The research findings can inform future policy and practice relevant to the exploration of health and (un)healthy bodies in health and physical education and health and physical education teacher education. 相似文献

Early childhood educators worldwide all strive to improve the quality of care and education for young children through sustainable pathways. One such pathway is professional development (PD). In the United States, ongoing PD has been recognized as critical to enhancing practitioners’ professional competence. Situated within the broader context of early childhood professional development systems, this study examined the New Jersey Infant/Toddler Credential (NJITC) as a case of PD. Specifically, we evaluated the effectiveness of the NJITC as PD by investigating its process as well as impact on the participating practitioners’ professional growth and practice from multiple perspectives: written reflections from a course instructor and a childcare center director; survey reflective responses from 12 practitioners; and informal conversations with childcare center directors, course instructors, field supervisors, and practitioners. The findings revealed that having the NJITC coursework offered through an onsite PD model and supported by a state-based scholarship program provided much needed incentives to encourage participation. It also resulted in improved professional growth and practice among the participating practitioners. However, it is only to the extent that the infant/toddler practitioners continue to engage in continuous PD beyond the ITC coursework will they be able to keep themselves abreast of the state of knowledge and best practices from which to further enhance their professional competence. In light of the process and impact of the NJITC on practitioners’ acquisition of specialized knowledge, skills, and dispositions to effectively work with infants and toddlers, implications and recommendations for policy are discussed. 相似文献

Since its inception, Sesame Street has modelled racial harmony; however, as a result of the rising racial unrest in the United States in 1989, we launched a four-year race relations curriculum initiative designed to be more explicit about physical and cultural differences, and to encourage friendship between people of different races and cultures. To assess children's basic knowledge and attitudes about diverse children living and playing together a variety of methods were developed, including a game 'Make a Neighborhood', to assess how living in a segregated environment influences preschoolers' understanding of race relations. The game allowed us to observe how preschoolers sort drawings of children who differ by race, clothing and hairstyle into places in the neighbourhood. Results indicated that Chinese American, African American, Puerto Rican and Crow Indian preschoolers integrated homes, schools, playgrounds, churches and stores when given drawings of children from their own groups and White children. White preschoolers integrated Chinese American and White, Puerto Rican and White and Crow Indian and White children in every structure. However, White preschoolers were significantly more likely to segregate African American and White children in the homes, schools, playgrounds, churches and stores. Based on these results, segments were produced which show White children visiting an African American friend's home. 相似文献

Over the past decades, there has been a substantial increase in post-secondary education participation in most Organisation for Economic Co-operation and Development (OECD) and European Union countries. This increase, however, does not necessarily reflect a parallel equitable growth in post-secondary education, and early school leaving is still an issue of concern in particular regions and countries across the world. This paper presents a study on increasing participation in post-secondary education in Malta, the country with the one of the highest proportions of early school leaving in the European Union. The study was carried out in a region with one of the highest rates of early school leaving in the country, making use of a phenomenological approach as well as a resilient systems perspective to early school leaving. On the basis of students’ narratives, the study identifies a number of risk and protective factors in early school leaving and makes various suggestions on how to build more resilient systems to facilitate access to post-secondary education, particularly for students coming from low socio-economic, excluded backgrounds. 相似文献

Differentiated thyroid carcinoma (DTC) generally has a favorable outcome. Thyroid disease, treatments, stress, and comorbidity
can compromise health-related quality of life (QoL) and indirectly weigh upon the outcome. From 2004 to 2008, we evaluated
QoL longitudinally in 128 DTC subjects. During scheduled examinations, subjects were asked to undergo a semi-structured psychiatric
interview and five rated inventories. The same examination was conducted in 219 subjects after surgery for benign thyroid
pathology. Low scores represent a better QoL. DTC and control subjects were similar in terms of age, male/female ratio, concomitant
psychopharmacological treatments, and frequency of psychiatric diseases. In DTC subjects, Billewicz scale (BS) scores showed
an increasing trend over time, especially among females. The ad hoc thyroid questionnaire (TQ) scores were similar in both
groups and did not change over time, but at the end of the study ad hoc TQ and BS were significantly related. Ad hoc TQ scores
were also related to age on entry to the study. In both male and female DTC subjects, Hamilton’s tests for anxiety (HAM-A),
but not for depression (HAM-D), showed an improving trend. At the end of the study, HAM-A and HAM-D scores were comparable
to those of the control group. HAM-A and HAM-D were both positively correlated with the stage of cancer and the time between
diagnosis and treatment. Only HAM-D correlated with age on entry to the study. Kellner symptom questionnaire (KSQ) item scores
were higher in DTC subjects than in controls. The change over time in the items including anxiety, somatization, depression,
and hostility was significant. Somatization and hostility were more significantly reduced in DTC females than in DTC males.
Hostility scores were significantly lower in DTC subjects than in controls at the end of the study. Somatization and depression
were significantly related to staging on diagnosis and age on entry to the study. Our study confirms a wide variation of illness
perception in DTC subjects, which is generally unrelated to the favorable clinical follow-up of the disease. Psychological
evaluation during long-term follow-up improved QoL scores, which reached the same levels noted in subjects with a history
of thyroid surgery for benign thyroid pathology. Our data indicate that special attention should be paid to QoL in older DTC
subjects and those with more severe staging on diagnosis. 相似文献
