Sign tracking in domesticated quail with one trial a day: Generality across CS and US parameters

When the conditioned stimulus (CS) is located some distance from the unconditioned stimulus (US), pairings of the CS and US can yield either conditioned approach to the CS (sign tracking) or conditioned approach to the US (goal tracking). However, goal tracking is the more common outcome, and, because of that, goal tracking has come to serve as a “standard” measure of associative learning in several laboratories. In contrast, in previous studies of sexual conditioning with domesticated quail, only sign tracking was observed. In the present study, quail continued to show sign tracking rather than goal tracking whether or not the US was highly localized (Experiment 1), whether food or a sexual US was used (Experiment 2), whether the CS was mobile or immobile (Experiment 3), and whether the CS was 91 or 233 cm from the US compartment (Experiment 4). The present findings encourage caution in the routine use of goal tracking as a measure of learning. The possible mechanisms of goal tracking are discussed in terms of occasion setting and behavior systems theory.     

New roles: professional staff sharing between a hospital and an academic library

Childrens Hospital Los Angeles is a pediatric hospital and research institute affiliated with the Keck School of Medicine of the University of Southern California (USC). Historically, the library at Childrens Hospital was staffed by a hospital-employed librarian. In 1999, the library position was outsourced to USC's Norris Medical Library. The new position is staffed by a librarian who divides her time equally between two locations: the Childrens Hospital Library and the Norris Medical Library. This staff sharing arrangement has three primary goals: increase the collaboration between the libraries; improve access to resources and library staff expertise; and provide faster document delivery service to the Childrens Hospital library. This paper presents the details of the position, and addresses the pros and cons for both libraries and the librarian.     

Managing geospatial data and services

Geographic information systems (GIS) are commonly misconceived as expensive and complicated map makers. Although GISs do create maps, they manipulate, organize, and display information, and aid in data documentation and accessibility. Managing GIS services involves, not just hardware and software issues, but managing digital data.     

What the framework means to me: Attitudes of academic librarians toward the ACRL framework for information literacy for higher education

Findings from in-depth interviews with academic librarians reveal initial perceptions of the value of the new Association of College and Research Libraries' Framework for Information Literacy for Higher Education and information about individual experiences in implementing the framework into information literacy skills instruction. Fifteen academic librarians, recruited through the ILI-L listserv, participated in Skype interviews that averaged 50?min in length. Participants shared that the Framework has had an impact on their teaching, helps them to better articulate the role of the librarian and the concept of information literacy, supports collaboration with faculty, and presents new empirical research opportunities for academic librarians. At the same time, acceptance of the Framework by librarians has not been universal, implementing the Framework into one-shot information literacy instruction is difficult, and full implementation of the Framework may require a restructuring of how information literacy education is approached.     

Ethnographic study of business students' information-seeking behavior: Implications for improved library practices

This study aim to gain insight into the information-seeking habits of upper-division business students. While studying information-seeking habits is a large subcategory of information literacy, not much has been published on the information-seeking habits of business students. The majority of studies conducted in this area use the survey as the data-collection instrument. This study uses ethnographic research methods such as journaling to collect data on this unique user group. Ethnographic methods allow the researcher to capture rich qualitative information that will yield a deeper and more nuanced understanding of the user group's needs. Findings are examined by using thematic qualitative analysis techniques. Information gathered for this study will be used to develop new services and information literacy components for business students.     

Children with asthma: Assessment and treatment in school settings

Asthma is a chronic disease of the airways. It affects approximately 12% of American children, and it appears that that incidence is increasing. Asthma in children negatively influences school‐based outcomes such as absenteeism and friendship formation. Potential triggers of asthma include environmental allergens, exercise, weather, and emotional states. These lead to airway swelling and muscle constriction, which ultimately block airflow and impede breathing. In addition to medical treatments, the implementation of psychologically based interventions has been efficacious in school settings. © 2007 Wiley Periodicals, Inc.     

Testosterone during Pregnancy and Gender Role Behavior of Preschool Children: A Longitudinal, Population Study

Levels of testosterone (T) and sex hormone–binding globulin (SHBG) were measured in blood samples from pregnant women and related to gender role behavior in 342 male and 337 female offspring at the age of 3.5 years. Gender role behavior was assessed using the Pre–School Activities Inventory, a standardized measure on which a parent indicates the child's involvement with sex–typical toys, games, and activities. Levels of T, but not SHBG, related linearly to gender role behavior in preschool girls. Neither hormone related to gender role behavior in boys. Other factors, including the presence of older brothers or sisters in the home, parental adherence to traditional sex roles, the presence of a male partner in the home, and maternal education, did not relate to gender role behavior in this sample and did not account for the relation observed between T and behavior. Although other, unmeasured factors may explain the relation, the results suggest that normal variability in T levels prenatally may contribute to the development of individual differences in the gender role behavior of preschool girls.     

Ethnicity and image: correlates of crowd affiliation among ethnic minority youth

Because ethnicity is a basis for defining peer crowds in ethnically diverse American high schools, some may question whether crowds foster discrimination and stereotyping or affirm minority youths' positive ties to their ethnic background. Through examination of both self- and peer ratings of crowd affiliation among 2,465 high school youth aged 14–19 years, this study assesses the likelihood that African American, Asian American, Latino, and multiethnic adolescents are associated with ethnically defined crowds. Crowd affiliations are related to friendship patterns among all groups, positive features of ethnic orientation for Asian and Latino youth, but also some aspects of stereotyping and discrimination for Latinos. Results emphasize ethnic diversity in the role that peer crowds play in minority adolescents' social experiences.     

Adult grandchildren’s perspectives on the grandparent-grandchild relationship from childhood to adulthood

The relationship between grandparents and grandchildren is usually quite close and satisfying, rather than conflictual, and is considered positive and important by both generations. The present study explores the nature of the relationship between grandparents and grandchildren in the United Kingdom. The aim of the study is to investigate adult grandchildren’s perspectives on the grandparent-grandchild relationship and its transition from childhood to adulthood. Using a Grounded Theory approach 10 young adults, aged 20–24, were interviewed about the relationship with their grandparents. Results showed that adult grandchildren perceive the relationship to continue from childhood to adulthood and to transition in terms of support, contact, attitude, and emotion. Support in childhood was reported as being more practical such as caregiving or help with education, whereas in adulthood as being more emotional. Contact was shown to be reduced from more frequent and face to face in childhood to less frequent and more telephone or internet based in adulthood. As to attitude and emotion participants reported a change in how they felt towards their grandparents from childhood to adulthood, with feelings of excitement being replaced with appreciation and respect. Implications of these transitions within grandparent-grandchild relationships are discussed.
