The present study dealt with the characterisation of marble surfaces coated by three kinds of polymeric material usually employed in stones conservation and with the evaluation of the removal of these coatings from the surfaces by means of new nanocontainer aqueous systems constituted of micellar solutions (MS) and oil-in-water microemulsions (MC). The polymeric coatings were also subjected to accelerated artificial ageing in order to detect possible effects associated to natural photochemical ageing. The aim of the work was the assessment of the performance of such nanocontainer aqueous systems taking acetone (Ac) as a reference “traditional” solvent for the removal procedure. The characterisation was carried out by means of Scanning Electron Microscopy (SEM) and Environmental Scanning Electron Microscopy (ESEM), Fourier Transform Infra-Red (FTIR) and Nuclear Magnetic Resonance (NMR) spectroscopies and the results obtained showed that the performance of these innovative methods based on nanocontainer aqueous systems can be considered highly promising in the view of a “green approach” to the conservation of cultural heritage.  相似文献

Increased awareness of the problem of child sexual abuse has resulted in increasing numbers of children presenting to professionals for the evaluation of possible sexual victimization. A multidisciplinary project to develop professionals' knowledge and skills in the identification and evaluation of possible victims is described. The program focused on the child as a victim and emphasized developmental perspectives with regard to identification, interviewing children, the medical examination, and children in the legal system. Fifty-one medical and social work professionals from ten Indiana counties attended the program and responded to questionnaires about their experience and knowledge. Of 40 (78%) respondents, 63% had had no previous training in the medical evaluation for child sexual abuse. Child protective workers referred alleged victims primarily to the child's regular physician (37%) or emergency room (31%) for medical examination. Knowledge about child sexual abuse improved significantly at two weeks postsymposium (p = .001) and remained improved at six months postsymposium (p less than .02). These original participants have subsequently organized similar multidisciplinary programs in their local communities for medical, social, law enforcement, and legal professionals; thus, they have been "seeds" for further educational and cooperative efforts throughout the state.  相似文献

Using prospective, longitudinal data spanning 10 years (age = 10–20) from a study of 295 economically disadvantaged males, the current investigation evaluated a developmental model that links early family environment and later educational aspirations, extracurricular activities, and educational attainment to substance use in early adulthood. The results indicate that a positive family environment during adolescence (low family conflict, high family warmth, and effective child management) predicted educational involvements during adolescence that promoted educational attainment during early adulthood. Finally, higher levels of educational attainment were associated with less substance use in early adulthood, even after controlling for adolescent substance use. These findings suggest that positive parenting promotes educational achievements that increase resilience to substance use for economically disadvantaged males.  相似文献

Transactional distance has been defined as barriers to students’ engagement with learning in the online environment. This research updates Zhang’s (2003) scale of transactional distance, which quantified the extent of the barriers, in light of the massive changes in today’s web-based learning environment. The resulting revised scale of transactional distance (RSTD) is a parsimonious version with 12 elements (compared to 31 original) that measure the transactional distance between student and teacher, student and student, and student and content. The RSTD has excellent factorial validity and reliability, yields better fit statistics, and is easier and less time-consuming to apply. The transactional distance values are unique predictors of student satisfaction, which is correlated to learning and persistence (a major concern with massive open online courses). This information can form the basis for a systematic approach to improving the design of today’s contemporary open, flexible, distance education courses and thus serve as a valuable tool for researchers and educators alike.  相似文献

The main purpose of the current study was to provide empirical evidence to support or refute assumptions of phenotypic deficits in motivation for children with Down syndrome (DS). Children with moderate intellectual disability (MID) associated with etiologies other than DS were recruited in an extension of a previous study that involved children with DS and typically developing children. The participants were 29 children with MID and 33 children with DS who were matched on mental age to 33 typically developing children, aged 3–8 years. Mastery motivation was assessed on task measures of curiosity, preference for challenge and persistence, as well as parental reports. There were no significant group differences on the mastery motivation tasks. Parental ratings of mastery motivation differed, with typically developing children generally being rated more highly than each of the disability groups. The view that motivational deficits are part of the DS behavioural phenotype was not supported.  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

We conducted a content analysis of generic qualitative counseling dissertations (GQR; N = 70), examining their methodological justifications, coherence, and trustworthiness. Dissertations authors often presented vague methodological justifications. Findings have implications for constructing methodological justifications, integrating relevant literature, and awareness of how GQR compares to other qualitative methodologies.  相似文献

This study investigated the associations between cultural diversity approaches endorsed by teachers and adolescents' positive and negative intergroup contact in schools. Participants were 984 adolescents (Mage = 14.66; 62.7% female; 24.8% ethnic minority) involved in a three-wave longitudinal study between 2019 and 2020. Results highlighted that perceived equal treatment by teachers was related to higher positive and lower negative contact over time. However, perceived support for contact and cooperation and interest of teachers in children's cultural background were not related to either positive or negative contact over time. Importantly, the results were replicated across ethnic minority and majority adolescents. This study provides novel insights into the key role that teachers can play in promoting cultural diversity approaches to facilitate harmonious intergroup interactions in schools.  相似文献

The relative age effect (RAE) refers to that children born early in their year of birth show higher performance compared to children born late in the same cohort. The present study evaluated whether RAE exists within non-competitive physical education (PE) attainments, change in RAE magnitude with age, and possible gender differences. The results show a drop in PE attainment and a difference in number of high and low marks between the first and second half-year. Of the pupils who attained the highest mark, 73% were born in the first 6 months. In lower-secondary school, RAEs were larger in girls compared with boys. A possible explanation for the results is that the PE-teachers might be inspired by product-oriented criteria.  相似文献
