Sexual violence and youth in South Africa: the need for community-based prevention interventions     

Petersen I  Bhana A  McKay M 《Child abuse & neglect》2005,29(11):1233-1248

OBJECTIVES: South Africa is reported to have one of the highest rates of sexual violence in the world, with adolescent girls between the ages of 12-17 being particularly at risk. Given that adolescence is considered a critical developmental period for establishing normative sexual behavior, this study explored multiple levels of risk influences that render adolescent girls vulnerable to becoming victims of sexual violence and adolescent boys vulnerable to becoming perpetrators of such abuse in one South African community. METHOD: A case study approach using qualitative rapid focused ethnographic methods was used. This involved 10 focus group interviews and 10 individual interviews with a volunteer convenience sample of adolescent boys and girls between the ages of 14 and 16 years. RESULTS: Inductive thematic analysis revealed that there were indeed multiple levels of risk influences for adolescent girls and boys becoming either victims or perpetrators of sexual violence. Using the Theory of Triadic Influence as a framework, influences at the distal socio-cultural/environmental level included traditional notions of masculinity and normalization of inter-personal violence as well as poverty and the commodification of sex leading to rape supportive attitudes. Influences at the proximal situation context/social normative level included high-risk social norms as well as a weak adult and community protective shield. Finally, influences at the intra-personal level included low self-esteem and self-efficacy as well as inter-personal affective anger. CONCLUSION: Given the multiple levels of risk influences that need to be addressed to protect youth from becoming either perpetrators or victims of sexual violence in the South African context, prevention programs should necessarily be comprehensive, developmentally timed, and community-based.  相似文献

Acts of Irreconcilable Mourning: Post-Holocaust Witness and Testimony     

Jill Petersen Adams 《Culture, Theory & Critique》2013,54(2):228-244

Abstract

This essay revisits the question of post-Shoah responses to cataclysm in light of the now-urgent question of transmission – the shift in mourning and memory between first-generation survivors and later generations. Offering a different but complementary analysis to those in trauma or memory studies, I argue that post-Shoah witness and testimony are acts of ‘irreconcilable mourning’. This sense of mourning departs from post-Freudian approaches that focus on closure. Instead, irreconcilable mourning is a non-totalising approach to loss that resists ‘redemption’ and instead necessitates an ongoing, creative, and critical response to loss. In the course of this argument, I examine first-generation accounts such as Primo Levi's and Elie Wiesel's to highlight the necessity and contingency of transmission by interrogating concepts such as the ‘unsayable’ and the remnant. I then focus on Art Spiegelman's second-generation Maus: A Survivor's Tale, bringing cross-generational questions of witness and testimony as acts of irreconcilable mourning into the fold of Marianne Hirsch's ‘postmemory’ and Edith Wyschogrod's heterological history-telling.  相似文献   

Imagining the possibilities: qualitative inquiry at the intersections of race,gender, disability,and class     

Amy J. Petersen 《International journal of qualitative studies in education》2013,26(6):801-818

This paper reflects upon the methodology and methods of a qualitative study that examined the lived educational experiences of four African-American women labeled with disabilities and from low socioeconomic backgrounds. This paper offers discussion as to the usefulness of alternate methods of representing data, specifically poetry and narrative, as a means of circumventing dilemmas associated with intersectional research and promoting more equitable research processes for individuals that have been historically marginalized by traditional research methods. How qualitative inquiry may enhance and bring about new insights into the lived experiences of individuals located at marginalized and intersecting discourses is explored.  相似文献   

Stop,Think, Do! Treating and Preventing Social-Behavioural Problems in School     

Lindy Petersen 《Pastoral Care in Education》2013,31(2):17-22

Most teachers will come into contact with pupils who are experiencing or have experienced a loss or bereavement and they often feel ill equipped to offer the kind of support they would like to. This paper offers insights into the nature of this area and a specific approach through which children may be supported. The writer discusses some research and thinking on loss and bereavement and the implications of this. She presents two case studies of work with individual students using the creative arts. She also discusses the connections between behavioural problems, loss and the use of the arts in supporting the students.  相似文献   

Behind the Screen: Visuality,Law, and New Media     

Jennifer Petersen 《Popular Communication》2014,12(3):166-177

The article analyzes the 2011 Supreme Court decision in which video games were granted full First Amendment protection. By comparing this case with earlier ones dealing with computer code, the article points to inconsistencies in how the courts are approaching digital media. These inconsistencies are symptomatic of a focus on the screen or the treatment of digital media as commodities. This status and the pervasive logic of commodity fetishism are what, in our current legal and economic environment, enabled the protection of games as pure speech. In actuality, the decision protected corporate rights and speech.  相似文献   

Effects of endurance training on transient oxygen uptake responses in cyclists   总被引：1，自引：0，他引：1  

Norris SR  Petersen SR 《Journal of sports sciences》1998,16(8):733-738

The aim of this study was to determine the alterations in oxygen uptake kinetics following endurance training in previously trained athletes. Sixteen competitive cyclists completed 8 weeks of supervised endurance cycle training. Ventilatory threshold, maximal oxygen uptake (VO2max), oxygen uptake kinetics and simulated 40-km time-trial tests were performed three times over a 4-week period before training, and then after 4 and 8 weeks of training. The protocol for measuring oxygen uptake kinetics consisted of three square-wave increments from unloaded cycling to a power output of 78 W followed by a single increment from 78 to 156 W. No significant differences in any variables were observed over the pre-training period. The ventilatory threshold and VO2max increased, and the time for 40 km decreased (P < 0.05) with training. Shorter VO2 time constants and lower heart rates were observed during the protocol for measuring oxygen uptake kinetics (same absolute power output) post-training. These results indicate that oxygen uptake kinetics may be improved with endurance training in previously trained athletes.  相似文献

The attitude of civil engineering students towards health and safety risk management: a case study     

A. K. Petersen  J. H. Reynolds  L. W.T. Ng 《European Journal of Engineering Education》2008,33(5-6):499-510

The highest rate of accidents and injuries in British industries has been reported by the construction industry during the past decade. Since then stakeholders have recognised that a possible solution would be to inculcate a good attitude towards health and safety risk management in undergraduate civil engineering students and construction professionals. Consequently, the four accreditation bodies that accredit construction degrees have improved coverage of health and safety risk management. The key issue has now shifted to ensure that Higher Education Centres deliver these requirements. This paper demonstrates innovative assessment methods that have been used to inculcate a safety conscious attitude into undergraduate civil engineering students, and to improve their knowledge of health and safety risk management. Surveys were administered to the students before and after they were subjected to innovative assessment techniques over two semesters in the construction management units. The analyses of the results of the surveys are provided to demonstrate the degree of improvement in the attitude of the students towards, and their knowledge of, health and safety risk management.  相似文献   

Linking item parameters to a base scale   总被引：1，自引：0，他引：1  

Taehoon Kang  Nancy S. Petersen 《Asia Pacific Education Review》2012,13(2):311-321

This paper compares three methods of item calibration??concurrent calibration, separate calibration with linking, and fixed item parameter calibration??that are frequently used for linking item parameters to a base scale. Concurrent and separate calibrations were implemented using BILOG-MG. The Stocking and Lord in Appl Psychol Measure 7:201?C210, (1983) characteristic curve method of parameter linking was used in conjunction with separate calibration. The fixed item parameter calibration (FIPC) method was implemented using both BILOG-MG and PARSCALE because the method is carried out differently by the two programs. Both programs use multiple EM cycles, but BILOG-MG does not update the prior ability distribution during FIPC calibration, whereas PARSCALE updates the prior ability distribution multiple times. The methods were compared using simulations based on actual testing program data, and results were evaluated in terms of recovery of the underlying ability distributions, the item characteristic curves, and the test characteristic curves. Factors manipulated in the simulations were sample size, ability distributions, and numbers of common (or fixed) items. The results for concurrent calibration and separate calibration with linking were comparable, and both methods showed good recovery results for all conditions. Between the two fixed item parameter calibration procedures, only the appropriate use of PARSCALE consistently provided item parameter linking results similar to those of the other two methods.  相似文献
