Unwanted and illegal sexual experiences in childhood and adolescence     

Nancy D. KelloggThomas J. Hoffman 《Child abuse & neglect》1995,19(12)

Three hundred forty-two anonymous surveys regarding unwanted sexual experiences (USE) were filled out in three clinic sites: a pediatric sexual abuse clinic, family practice clinic, and family planning clinic. In the latter two clinics, 40% of females and 16% of males had at least one unwanted sexual experience prior to turning 18 years old. Only 91% of the sexual abuse clinic patients indicated their experience was unwanted. In addition, 27% of the subjects had wanted sexual experiences that were illegal and underreported: These experiences involved a partner at least 4 years older or younger. While feelings of victimization were most common, self-blame and naivete about the abuse were also frequently reported, especially in those who had an USE with a peer. Ambivalence, self-blame, and peer pressure were associated with a lower tendency to disclose one's USE. Although unwanted and illegal sexual experiences were less common in Hispanic females, feelings of self-blame and ambivalence regarding their USE were more frequent in comparison with White females. These findings have important investigative and therapeutic implications for professionals who encounter victims of sexual abuse.  相似文献   

A New Marketing Paradigm for Electronic Commerce   总被引：11，自引：0，他引：11  

Donna L. Hoffman Thomas  P. Novak 《The Information Society》1997,13(1):43-54

The World Wide Web possesses unique characteristics that distinguish it in important ways from traditional commercial communications environments. Because the Web presents a fundamentally different environment for marketing activities than traditional media, conventional marketing activities are becoming transformed, as they are often difficult to implement in their present form. In this article, we discuss the idea that these changes portend an evolution in the 'marketing concept' and argue that in order for marketing efforts to be successful in this new medium, a new business paradigm is required. In this new approach, the marketing function must be reconstructed to facilitate electronic commerce in the emerging electronic society underlying the Web.  相似文献   

How is radial arm maze behavior in rats related to locomotor search tactics?     

Cynthia M. Hoffman  William Timberlake  Joseph Leffel  Rory Gont 《Learning & behavior》1999,27(4):426-444

Norway rats have been shown to depend on short-term spatial memory to find food on a radial arm maze (RAM), but what locomotor search tactics are involved in using this memory effectively? Four experiments distinguished tactics of distance minimizing, central-place search, trail following, thigmotactic search, and random search by using different configurations of a RAM placed flat on the floor of an arena. These search tactics make similar predictions on an elevated RAM but predict different outcomes on a floor RAM because the rats are free to approach the food from any direction. After initial trials dominated by exploration, rats traveled along arms to food, even when the resultant distance was up to three times the minimum distance. With no food present, rats also traveled along arms; with no arms up to present, they traveled along walls to food. It appears that both maze arms and arena walls engage mechanisms related to trail following in rats.  相似文献   

The pursuit of useable knowledge in instructional technology     

Rita C. Richey 《Educational technology research and development : ETR & D》1998,46(4):7-22

The object of inquiry in instructional technology is not simply knowledge, but useable knowledge. This paper explores the dimensions of relevance with respect to research and suggests ways the research community can accommodate the needs and interests of practicing professionals in the field. Research relevance is examined as a reflection of: (a) practitioner and disciplinary values; (b) perceived credibility, viewed in terms of authenticity, methods employed, and replicability; and (c) perceptions of utility based upon the concrete nature of the findings. Specific recommendations relate to expanding the range of topics addressed in our research, expanding the range of research methods employed, orienting our research communication to specific practitioner communities, conducting research under natural conditions, replicating research, and establishing links between abstract and concrete findings. Finally, the role of the practitioner as an educated consumer of research is discussed.  相似文献   

Zum Problem der Hochschulreform in Spanien: Einige Ausgewählte Daten     

Val  José Cajide  Philipp  Rita Radl  Castro  Ana Porto 《International Review of Education/Internationale Zeitschrift für Erziehungswissenschaft/Revue internationale l'éducation》1998,44(5-6):583-596

Over the past ten years there has been a sweeping reform of the courses taught and qualifications awarded by Spanish universities. For that reason, an investigation was launched in 1996–97 at the University of Santiago de Compostela (in Northwest Spain) into the teaching, research and management entailed in four new degree courses: physics (years one to four), agricultural engineering (first and second years), agricultural food-processing technology (years one to three) and pharmacy. This article reports on students' opinions of the reforms in these courses, revealing dissatisfaction with facilities for practical course work, lack of connection with prospective employment, and a call for more information about courses.  相似文献   

Silk Road: The market beyond the reach of the state     

Rita Zajácz 《The Information Society》2017,33(1):23-34

Between February 2011 and October 2013, Silk Road operated the largest and most sophisticated anonymous online marketplace for illegal drugs. More than a business venture, it was designed for anarcho-capitalist resistance to state power. The primary research question of this inquiry is: Can a stable market, defying the state, emerge under conditions of online anonymity? The article shows that Silk Road was built on a contradiction. On the one hand, strong cryptographic anonymity was embraced because it facilitated hiding from the state. On the other hand, the very same cryptographic anonymity made it difficult to impose rules and create a stable market. Silk Road sought to cultivate subcultural norms to ensure proper behavior in face of anonymity but they were not strong enough to control the behavior enabled by its architecture.  相似文献   

A History of Infant Feeding          下载免费PDF全文

Emily E Stevens  Thelma E Patrick  Rita Pickler 《The Journal of perinatal education》2009,18(2):32-39

The historical evolution of infant feeding includes wet nursing, the feeding bottle, and formula use. Before the invention of bottles and formula, wet nursing was the safest and most common alternative to the natural mother''s breastmilk. Society''s negative view of wet nursing, combined with improvements of the feeding bottle, the availability of animal''s milk, and advances in formula development, gradually led to the substitution of artificial feeding for wet nursing. In addition, the advertising and safety of formula products increased their popularity and use among society. Currently, infant formula-feeding is widely practiced in the United States and appears to contribute to the development of several common childhood illnesses, including atopy, diabetes mellitus, and childhood obesity.  相似文献   

The City of Richgate: A/r/tographic Cartography as Public Pedagogy

The City of Richgate project worked with eight intergenerational immigrant families and examined immigrant experiences and narratives through a community‐engaged process that employed a/r/tography as a methodology. As such, the research also investigated the extent to which a/r/tographical research could visually and narratively portray the analysis of data collected by the co‐a/r/tographers. After interviewing and collecting images from each family, large artistic gates (banners) were created. This first phase of the project revealed the power of images in situ, and thus the power of a/r/tography in situ. For the community members and co‐a/r/tographers meanings were constructed within ongoing a/r/tographic inquiries described as collective artistic and educational praxis. The second phase involved the identification of important places by each family within the City of Richmond. After analysing all of the data, several works of art were created with each family in mind: bus shelter images juxtaposing close‐up and far away geographical images; side‐by‐side images portraying historical and contemporary images of family ideals and/or issues; banners illustrating families in meaningful poses; and archival collections portraying the importance of identity and memory in the transformation of culture. This phase culminated in a citywide exhibition of the artwork performing public pedagogy. The exhibition questioned the idea of a City of Richmond having a community centre, and instead exhibited many Richgates, or conceptions of Richmond. Rather than having a city centre, there are many centres, a Network of Cities of Richgates, where centres are constantly changing and shifting to reflect the narratives of individuals living in a psycho‐geographical region of a city.  相似文献   

In pursuit of the effective neighborhood information system: User-friendliness and training     

Sungsoo Hwang  Mark C. Hoffman 《Government Information Quarterly》2009

The goal of this research is to address the effectiveness of Neighborhood Information Systems (NIS) as an Information Technology (IT) tool in assisting community development. NISs are hybrid applications of Geographical Information Systems (GIS) and web technologies that provide demographic, social, and economic information to community stakeholders. Government agencies, nonprofit organizations, and community organizations engage in decision-making process for community development, and NISs are designed to help information-sharing and effective and participatory decision-makings for community development stakeholders.  相似文献   

Educational leadership and social activism: a call for action   总被引：1，自引：1，他引：0  

Lauren P. Hoffman 《Journal of educational administration and history》2009,41(4):391-410

The purpose of this article is to argue for a social activist stance in educational leadership that fundamentally addresses social change and human emancipation. This call for social activism is framed within neoliberal, neoconservative, and authoritarian populist discourses in the USA, which to social justice educators and leaders had devastating effects on education. Empirical data from an activist high school principal, activist university professor, and activist priest reflects their development of political clarity, political capacity, political collaboration, and an ethic of risk. It is suggested that the work of socially active educational leaders needs to be broadened to include such things as public policy advocacy, networking, organising, community development, and scholarship. Finally, the article concludes with a variety of ways educational leaders can demonstrate their social, moral, and political activism as they challenge the status quo, fight for social justice, and come to understand the politicised notion of leadership.  相似文献
