Paths to Protecting Patron Privacy

The “Digital Trends and the Global Library Community” column examines technological advances internal and external to libraries. The focus is on how technology is changing the way services are provided to users, the methodologies used in the provision of those services, and the resulting scope of responsibilities of libraries and parent institutions.

A review of models of vertical, leg, and knee stiffness in adults for running, jumping or hopping tasks

Abstract The 'stiffness' concept originates from Hooke's law which states that the force required to deform an object is related to a spring constant and the distance that object is deformed. Research into stiffness in the human body is undergoing unprecedented popularity; possibly because stiffness has been associated with sporting performance and some lower limb injuries. However, some inconsistencies surrounding stiffness measurement exists bringing into question the integrity of some research related to stiffness. The aim of this study was to review literature which describes how vertical, leg and knee stiffness has been measured in adult populations while running, jumping or hopping. A search of the entire MEDLINE, PubMed and SPORTDiscus databases and an iterative reference check was performed. Sixty-seven articles were retrieved; 21 measured vertical stiffness, 51 measured leg stiffness, and 22 measured knee stiffness. Thus, some studies measured several 'types' of stiffness. Vertical stiffness was typically the quotient of ground reaction force and centre of mass displacement. For leg stiffness it was and change in leg length, and for the knee it was the quotient of knee joint moments and change in joint angle. Sample size issues and measurement techniques were identified as limitations to current research.     

Social Understanding in Young Israeli-Jewish,Israeli-Palestinian,Palestinian, and Jordanian Children: Moral Judgments and Stereotypes

Research Findings: An empirical investigation was conducted to test young Palestinian, Jordanian, Israeli-Palestinian, and Israeli-Jewish children's (N = 433; M = 5.7 years of age) cultural stereotypes and their evaluations of peer intergroup exclusion based upon a number of different factors, including being from a different country and speaking a different language. Children in this study lived in a geographical region that has a history of cultural and religious tension, violence, and extreme intergroup conflict. Our findings reveal that the negative consequences of living with intergroup tension are related to the use of stereotypes. At the same time, the results for moral judgments and evaluations about excluding peers provide positive results about the young children's inclusive views regarding peer interactions. Practice: These findings indicate that practitioners working with young children should focus on inclusion in peer contexts. Curricula, media, and social intervention programs must begin in early childhood before children begin to use stereotypes in peer situations, particularly when children from other cultural and ethnic backgrounds play together.     

Exploring identities to deepen understanding of urban high school students' sexual health decision‐making

Sexual health is a controversial science topic that has received little attention in the field of science education, despite its direct relevance to students' lives and communities. Moreover, research from other fields indicates that a great deal remains to be learned about how to make school learning about sexual health influence the real‐life choices of students. In order to provide a more nuanced understanding of young people's decision‐making, this study examines students' talk about sexual health decision‐making through the lens of identities. Qualitative, ethnographic research methods with twenty 12th grade students attending a New York City public school are used to illustrate how students take on multiple identities in relation to sexual health decision‐making. Further, the study illustrates how these identities are formed by various aspects of students' lives, such as school, family, relationships, and religion, and by societal discourses on topics such as gender, individual responsibility, and morality. The study argues that looking at sexual health decision‐making—and at decision‐making about other controversial science topics—as tied to students' identities provides a useful way for teachers and researchers to grasp the complexity of these decisions, as a step toward creating curriculum that influences them. © 2010 Wiley Periodicals, Inc.

Disabling conditions: Investigating instructional leadership teams in action

This study investigated why and how principals selected members for their instructional leadership team (ILT) and how this selection criteria and process may have impacted team members’ understandings of, and behaviors on, the team. Qualitative methods, specifically interviews and observations, were used to explore team members’ perceptions regarding the team’s purpose, function, and selection criteria as well as how these perceptions seemed to impact team members’ behaviors. Data were collected for a period of 8 months during the 2011–2012 school year from ILT in four, in-district charter schools. Results suggest that principals had difficulty articulating their teams’ purposes and functions, with the latter remaining primarily informational or consultative; members were not given decision-making authority. Additionally, when selecting team members, principals prioritized broad representation of teacher groups over other criteria. This focus on role representation above expertise, coupled with teachers’ tendencies to embrace traditional professional norms, limited ILT members’ abilities to effectively work together to lead instructional reform.
