The role of gender constancy in early gender development

Kohlberg's (1966) hypothesis that the attainment of gender constancy motivates children to attend to gender norms was reevaluated by examining these links in relation to age. Ninety-four 3- to 7-year-old children were interviewed to assess whether and how constancy mediates age-related changes in gender-related beliefs. As expected, results indicated a general pattern of an increase in stereotype knowledge, the importance and positive evaluation of one's own gender category, and rigidity of beliefs between the ages of 3 and 5. Moreover, the stability phase, rather than full constancy, mediated some of these relations. After age 5, rigidity generally decreased with age, with relations primarily mediated by consistency.     

Cut points of the Actigraph GT9X for moderate and vigorous intensity physical activity at four different wear locations

ABSTRACT

Accelerometer cut points are an important consideration for distinguishing the intensity of activity into categories such as moderate and vigorous. It is well-established in the literature that these cut points depend on a variety of factors, including age group, device, and wear location. The Actigraph GT9X is a newer model accelerometer that is used for physical activity research, but existing cut points for this device are limited since it is a newer device. Furthermore, there is not existing data on cut points for the GT9X at the ankle or foot locations, which offers some potential benefit for activities that do not involve arm and/or core motion. A total of N = 44 adults completed a four-stage treadmill protocol while wearing Actigraph GT9X sensors at four different locations: foot, ankle, wrist, and hip. Metabolic Equivalent of Task (MET) levels assessed by indirect calorimetry along with Receiver Operating Characteristic (ROC) curves were used to establish cut points for moderate and vigorous intensity for each wear location of the GT9X. Area under the ROC curves indicated high discrimination accuracy for each case.     

Review of criteria used to measure library effectiveness

This article reports the results of a survey of literature on measures of library effectiveness. This survey led to the formulation of six criterion concepts (accessibility, cost, user satisfaction, response time, cost/benefit ratio, and use). The advantages and disadvantages of each method of measurement are discussed. Several points which became clear during the analysis are discussed. First, there is a relative lack of concern with the rationale behind the evaluation process, although the results invariably lead to a confused interpretation when there is no clear understanding of the purpose of an evaluation. Second, the total library system is rarely considered; instead, each evaluation criterion is taken in isolation rather than as part of the whole. Third, the library's preservation function has not been considered at all.     

Wear Attitude Inventory Applied to Junior High School Boys

Abstract

Form A of the Wear Attitude Inventory was administered to one randomly selected physical education class of seventh grade boys, one class of eighth grade boys, and one class of ninth grade boys in each of five junior high schools. The mean Inventory score for each grade was found to be equal to or superior to the mean reported in Wear's validation study. A significant X₂ value was found for the distribution of Inventory scores of the three junior high school grades. A biserial coefficient of correlation item analysis which was computed for each of the three grades established that the 30 items correlated significantly with the total score and that the item score also had a significant correlation with the Inventory category score. On the basis of these results, the conclusion was advanced that the Wear Attitude Inventory was an appropriate instrument to measure attitudes of junior high school boys toward physical education.

Build Your Program by Building Your Team: Inclusively Transforming Services,Staffing and Spaces

ABSTRACT

User feedback told the story of the largest and busiest campus library being dated in both physical form and programmatic function. Under the framework of a newly-developed strategic plan, library leadership initiated a comprehensive and inclusive assessment program to understand fully user needs by engaging users, campus partners, and, importantly, library personnel. Simultaneously, they embarked on a review of change management literature for guidance on implementing the required transformation. Informed by the change management philosophy of John Kotter, the library utilized the findings of the assessment program to craft and implement a sustainable transformation of its services, staffing, and spaces.

Language and reading impairments are associated with increased prevalence of non-right-handedness

Handedness has been studied for association with language-related disorders because of its link with language hemispheric dominance. No clear pattern has emerged, possibly because of small samples, publication bias, and heterogeneous criteria across studies. Non-right-handedness (NRH) frequency was assessed in N = 2503 cases with reading and/or language impairment and N = 4316 sex-matched controls identified from 10 distinct cohorts (age range 6–19 years old; European ethnicity) using a priori set criteria. A meta-analysis (N_cases = 1994) showed elevated NRH % in individuals with language/reading impairment compared with controls (OR = 1.21, CI = 1.06–1.39, p = .01). The association between reading/language impairments and NRH could result from shared pathways underlying brain lateralization, handedness, and cognitive functions.
