Autobiographies of B’nai Mitzvah: The Meaning of B’nai Mitzvah and the Role Adolescents Believe Adults Play in the Process

ABSTRACT

B’nai mitzvah is a significant motivation for engagement in Jewish education. Professionals and families devote resources in aiding young people in becoming b’nai mitzvah. This article examines the adolescent narratives of b’nai mitzvah and the ways in which adults feature in their stories. Their accounts surface a belief that adults support them through pep talks, expressions of pride, helping them make choices, and being with them through the process. Teens see themselves responsible for their choices and achievements, but are appreciative of support. This article raises questions about what ways and by whom adolescents should be guided and supported.     

Reliability of unipodal and bipodal counter movement jump landings in a recreational male population

Movement patterns during landing have been suggested to be related to injury risk. The purpose of this study was to determine the inter-session reliability of kinematic variables and ground reaction forces during landing in a population of male recreational athletes after a counter movement jump. Both unipodal and bipodal landings were evaluated. Furthermore, the possibility to improve landing reliability with a verbal instruction was also studied. Twenty-four male volunteers with no history of lower extremity trauma were randomly assigned to two groups (with and without verbal landing instruction). An optoelectronic 3D system and force plates were used to measure the lower limb joint angles and the ground reaction forces during landing. Intraclass correlation values show moderate to excellent inter-session reliability for the bipodal task (ICC average: 0.80, range: 0.46–0.97) and poor to excellent reliability for the unipodal task (ICC average: >0.75, range: 0.20–0.95). However, large standard errors of measurement values at the ankle joint at impact (27.6?±?11.5°) and for the vertical ground reaction forces (394?±?1091 N) show that some variables may not be usable in practice. The verbal instruction had a negative effect on the reliability of unipodal landing but improved the reliability of bipodal landing. These findings show that the reliability of a landing task is influenced by its motor complexity as well as the instruction given to the subject.     

Online News Coverage of Preexposure Prophylaxis

Human immunodeficiency virus, or HIV continues to be a serious issue, especially for men who have sex with men (MSM). A new means of HIV prevention, called preexposure prophylaxis (PrEP), significantly reduces the chance of HIV infection. However, adoption of the drug has been slow. In this study, a content analysis of 234 online news articles about PrEP from popular U.S. news Web sites was conducted, focusing on how articles were framed in terms of benefits to PrEP, barriers to PrEP, the severity of HIV, and the susceptibility of MSM to HIV. Results showed that coverage contained conflicting information about PrEP and failed to cast HIV as a serious problem.     

Modeling scholarly book literature

Recent technology provides the means to gauge the declining ability of the nation's research libraries to maintain fairly comprehensive book collections in the face of the extraordinary growth and price inflation of scholarly publishing since the 1970s. An application of this technology is presented here in the form of a model of total book publication output and the aggregate holdings of 71 research libraries in a selected field, general sociology, for the period 1979–88. The usefulness of such modeling is discussed in terms of generating knowledge that, while low on precision, has broad reliability and relevance.
