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

Abstract

There are a few studies in library literature that explore accessibility issues from the perspective of students who use assistive technologies for accessibility. As we shared in part one of this two-part series in our column, librarians have extensively explored through usability studies with WAVE and other audit tools how accessible library websites and databases are when using assistive technologies like JAWS. In this column, we asked our blind student worker to journal his experiences navigating our library’s databases. We found this student navigated the databases better than we anticipated. While his experiences regarding the accessibility of the libraries’ electronic services varied, common issues he experienced included navigational issues from menus with expanding capabilities, documents that were not scanned with OCR, and images without alternative text.  相似文献

Research examining family influences on student motivation and achievement in school has generally focused on parental influences and has often been limited to one or two variables (e.g., parental expectations or aspirations, parental involvement in schoolwork). In the present study we interviewed high school seniors to examine whether and how family members affected their academic motivation and achievement. Interviews were coded holistically for the strength, affective tone, source, and types of familial influence. Emergent themes from the interview analyses revealed that students perceived a broad range of types and sources of familial influence on motivation. Interviews were divided into five prototypical patterns: Family Obligation, Family Pleasing, Family Support, Aversive Influence, and No Influence. The types of familial influence differed by cultural characteristics (generational status, native country) and by achievement level. Associations between the five patterns of family influence and existing theories of family influence are discussed.  相似文献

In the 2015 Summer Session I, the information literacy team combined two instruments, the Information Literacy Assessment (ILA) and the Students' Perceptions of Their Information Literacy Skills Questionnaire (SPIL-Q), into one survey and distributed it to the college's international graduate students through a Google Form. It was distributed to 932 international graduate students, and 172 valid respondents completed the survey. The purpose of this research was to compare the confidence gap in information literacy skills between men and women, particularly in international graduate students. Data collected illustrated that female international business students (n = 70) tended to be slightly more confident than their male counterparts (n = 102) regarding their perceived information literacy skills as evidenced by their SPIL-Q average score across all six IL topics, 3.78, vs. male student's average score of 3.58.  相似文献

This study was conducted to test whether group identification (importance of the group to the individual) covaried with individual-group similarity on problem behavior; and whether group identification moderated peer group influence on the individual's development of delinquent behavior across a 1-year period. The level of reciprocated nominations within the individual's self-nominated group was controlled for in all analyses. Participants were 190 sixth and seventh graders (during the first year of the study) from the north of Italy. Level of reciprocated nominations within the group, but not identification, was found to covary with individual-group behavioral similarity (group behavior interacted with reciprocity of group nominations in predicting individual behavior). Group identification, but not reciprocated nominations, was found to moderate peer group influence on the individual's change in delinquent behavior, across 1 year. The individual's peer status within the classroom, level of reciprocated nominations, and gender all were related to the individual's level of group identification. Results are discussed in terms of understanding peer group influence on the individual.  相似文献

Implementing discovery tools and getting them to work with existing library services often leaves very little time for their promotion and for the thoughtful, ongoing evaluation and curation of their content. However, the expectations and experiences that users have about discovery tools are often directly related to the content and the way that content is described. In our efforts to work with vendors to resolve the underlying business issues that prevent us from having all of the metadata for our resources included in our discovery tools, we may have lost sight of our role in curating and evaluating the usefulness of the content that is already included in them.  相似文献
