BackgroundThe current state of knowledge regarding the role of non-offending fathers in supporting their sexually abused children is very scarce.ObjectiveThe objective of this study is to further our understanding of fathers’ roles following disclosure of their children’s sexual abuse (SA) by evaluating fathers’ perceptions of the impact of disclosure on their involvement and support of their children.Participants and methodThis qualitative study relies on individual semi-structured interviews conducted with 17 fathers of allegedly abused children.ResultsInductive thematic analysis first highlighted that some reported a period of disengagement from the child during which they put into question their role and attitudes, followed by a period of re-involvement. This period of difficulties experienced by some fathers in regard to their involvement towards their children was due to either their own important psychological distress, their ambivalence towards their child or even because of feelings of uneasiness experienced during physical contact with them. Despite this, findings indicate the presence of thoughts and attitudes that suggest children are a source of concern for fathers. The four forms of abuse-specific support previously observed among mothers (believing the child, seeking out professional services, protecting him/her from the offender, supporting him/her emotionally) were also observed among fathers. In accordance with the activation theory, a form of support specific to fathers, namely, encouraging the child to open up to and explore the world outside the family, thereby, fostering the child’s self-esteem development, was observed and constitutes a relevant finding.ConclusionClinical and empirical implications are discussed. 相似文献

This study investigates how journalists covering international humanitarian crises make decisions regarding what types of information to include in stories. Specifically, the inclusion/exclusion of solutions-oriented information is addressed, since crises represent a key time during which the potential for international engagement is discussed in the mainstream media. Interviews with journalists covering hunger crises in Africa reveal an internal tension between maintaining a neutral, unbiased position and writing in a way that supports engagement and action. Ironically, perhaps, journalists find that including solutions-oriented information amounts to unethical and biased coverage, despite the fact that inclusion of solutions to social problems is an accepted and institutionalized aspect of the US news media’s mandate to the public. Reasons for this seeming contradiction are discussed, and I argue that solutions-oriented information not only can be included without demonstrating bias, but that it ought to be included to support ethical coverage that properly informs citizens about potential paths for political engagement. 相似文献

Abstract This paper provides a methodology to study the characteristics of the research output from a university department. The faculty publications and their cited references over a 10-year period were used as the basis for this study to identify their publishing patterns and the types of material they are publishing; a core set of journals and other resources they are publishing in and citing over this period; the characteristics of the journals in which they publish and cite; the degree of openness of their publications and their citation advantage; and the age of resources that are referenced. 相似文献

AbstractBIBCO is one of four programs in the PCC. This article summarizes the development of BIBCO and how its cataloging training program was strikingly different from the other three programs: NACO, CONSER and SACO. BIBCO grew out of the 1990–1991 recession which created widespread anxiety over the cost of original cataloging. BIBCO attempted to reduce the cost without sacrificing quality and increase record production through the use of core records. The early training emphasized the value of cooperation. PCC’s strength in this area is seen today in its partnerships and leadership in metadata initiatives such as linked data. 相似文献

AbstractIn an economic climate when colleges can no longer presume that legislators see institutions of higher learning as tacit public goods, institutions around the country are facing budget cuts. This article presents a case study of the experience of a mid-sized public state university and its Library in a budget crisis undergoing a university-wide program prioritization process. The authors review the process of writing three reports on the Library’s value, along with the approach to engaging staff in the process including a retreat. This article raises questions about what every library should consider assessing and provide tools for libraries navigating similar terrain. 相似文献

AbstractThis study examined a project that delivered social work services to homeless individuals. A mixed-methods case study was conducted using quantitative and qualitative data from 93 library employees and the project’s Homelessness Prevention Outreach Worker (HPOW). There was an increase in the number of clients accessing community supports during the project, and the HPOW was integral to the provision of support and resources to homeless individuals. Staff training was associated with significantly greater knowledge, comfort, and skills in working with homeless individuals. These findings can inform the delivery and implementation of similar programs for homeless individuals. 相似文献
