The elimination of spray paint using traditional (chemical and mechanical) methods inevitably entails altering surface characteristics. Hence, the impact and deterioration caused by graffiti in heritage buildings and monuments have led to the development and application of preventive systems in the form of antigraffiti coatings (which prevent paint from seeping into the pores of the surface material and facilitate cleaning). The effectiveness of two of these treatments, a commercial product (fluoroalkyl siloxane, protectosil, marketed by Degussa) and a hybrid organic-inorganic material (Ormosil), was evaluated in five construction materials (limestone, granite, cement mortar, lime mortar and brick), in terms of their penetration into the substrate. A number of techniques were used to determine the penetration depth (SEM/EDX, micro-Raman and LIBS), because a comparative analysis showed that none was universally valid for all types of treatments. The results show that the presence of the coating on the surface of less porous materials only ensures effective cleaning when the surface is fairly smooth. In granite, for instance, the CF3 terminals in the fluorinated treatment hinder spray paint bonding more effectively than Ormosil, but not efficiently enough to ensure complete removal of the paint from granite surfaces. 相似文献

Objective: This study evaluated the emotional and behavioral adjustment of parents and children within 3 months and 1 year after the discovery of child extrafamilial sexual abuse.Method: Ninety-two case parents (63 mothers, 29 fathers) and 56 children were compared to a nonclinical comparison group of 136 parents (74 mothers, 62 fathers) and 75 children. Parent adjustment was assessed using self-report measures while child functioning was assessed using a combination of child-, parent- and teacher-report measures.Results: Mothers, fathers and sexually abused children experienced clinically significant effects both initially and at 12 months post-disclosure. Children’s perceptions of self-blame and guilt for the abuse and the extent of traumatization predicted their self-reported symtomatology at 3 months and 1 year post-disclosure. Child age and gender also significantly contributed to the prediction of many of the child outcome measures. No abuse-related variable was related to any child self-report measure. Mothers’ satisfaction in the parenting role, perceived support and intrusive symptoms predicted their initial emotional functioning. Avoidant symptoms, child’s internalizing behavior and mothers’ initial emotional functioning were significant predictors of longer-term emotional functioning.Conclusions: Results emphasize the need to address children’s abuse-related attributions and underscore the need to expand our focus beyond the child victims to the traumatized families. 相似文献

Family child care providers contend with a number of work stressors related to the dual roles of operating a small business and providing child care in their home. Research has documented many sources of work related stress for family child care providers; however, research examining family child care providers’ experiences outside of the lens of quality of care and child outcomes is dated and scant. This study consisted of three focus groups of 11 family child care providers who shared their perspectives on work related stressors and well-being. Many of the study findings were congruent with previous research in the field; however, a key finding in this study was the importance of family child care providers to assert and establish a professional identity to mitigate work related stress. Recommendations and strategies to assist family child providers in constructing a professional identity are discussed. 相似文献

Drawing upon the notions of academic capitalism and the transformation of academic research from traditional academic orientation
into market orientation, the paper sets out to empirically scrutinize the changing nature of academic research, focusing especially
on disciplinary differences. The paper is based on a survey of heads of departments and research units at Finnish universities
representing all disciplinary groups (n = 255) and on in-depth interviews with Finnish academics (n = 31) in the fields of humanities, social sciences, technology and natural sciences. Based on the survey data, the funding,
selection of research topics, collaboration partners, audiences and publication forums in research are analysed. Following
this, five research markets are discerned: academic, corporate, policy, professional and public market, each characterized
by its own values and rationality as to what is considered the reference group, basic objective and outcome of research. The
paper concludes that the transformation thesis needs to be revisited and specified since on the one hand, academic orientation
still remains crucially important in all disciplinary groups, and on the other hand, market orientation entails several kinds
of markets, pointing to the versatility of the university–society relationship. 相似文献

Although the impact of early adverse experience on neural processing of face familiarity has been studied, research has not taken into account disordered child behavior. This work compared the neural processing of familiar versus strangers' faces in 47 institutionalized children with a mean age of 54 months to determine the effects of (a) the presence versus absence of atypical social behavior and (b) inhibited versus indiscriminant atypical behavior. Results revealed a pattern of cortical hypoactivation in institutionalized children manifesting atypical social behavior and that inhibited children displayed larger neural response to a caregiver's face than to the stranger's, while indiscriminant children did not discriminate between stimuli. These findings suggest that neural correlates of face familiarity are associated with social functioning in institutionalized children. 相似文献
