Are validity coefficients understated due to correctable defects in the GPA?

The predictive validity of preadmissions measures such as standardized test scores and high school grades may be understated because of correctable defects in both the freshman year and cumulative grade point average (GPA). Measurement error in the criterion artificially depresses the size of observed validity coefficients. A study was conducted using item response theory (IRT) to develop a more reliable measure of performance, called an IRT-based GPA, and tested in a predictive validity study using data from Stanford University. Results indicate increased predictability when the IRT-based GPA is compared with the usual GPA.This article is based, in part, on the doctoral dissertation of the author, which was completed at the School of Education at Stanford University.     

Social competence, sense of loneliness, and speech intelligibility of young children with hearing loss in individual inclusion and group inclusion

The study focused on social competence (SC) and perceived sense of loneliness of preschool children with hearing loss (HL) in group inclusion (GI, a small group of children with HL is integrated in a standard classroom) and individual inclusion (II, each child with HL is individually integrated into a standard classroom). The relations between these factors and the child's speech intelligibility were performed. Sixty-four children aged 4-7 years participated: 22 from an II and 42 from a GI. SC, perceived sense of loneliness, and speech intelligibility were evaluated through the use of questionnaires completed by the preschool teachers. The results showed that the SC of children in II was higher than the SC of the children in GI, while interacting with normal hearing (NH) children. In GI, the children's SC with other children with HL was higher compared with their SC with NH children. In both groups, there were relationships between speech intelligibility and SC with NH children. In addition, in the II setting, there were relationships between the speech intelligibility and the perceived sense of loneliness. These relationships were not found in the GI setting. The findings support the need for coenrollment of preschool children with HL and emphasize the crucial impact of speech intelligibility of children with HL on the success of their social enrollment with NH children, already at a young age.     

Variations on variability: effects of display composition on same–different discrimination in pigeons

Discriminating same from different multiitem arrays can be represented as a discrimination between arrays involving low variability and arrays involving high variability. In the present investigation, we first trained pigeons with the extreme values along the variability continuum (arrays containing 16 identical items vs. 16 nonidentical items), and we later tested the birds with arrays involving intermediate levels of variability; we created these testing arrays either by manipulating the combination of same and different items (mixture testing) or by changing the number of items in the same and different arrays (number testing). According to an entropy account (Young & Wasserman, Journal of Experimental Psychology: Animal Behavior Processes 23:157?C170, 1997), the particular means of changing variability should have no effect on same?Cdifferent discrimination performance: Equivalent variability should yield equivalent performance. In this critical test of an entropy account, we found that entropy could explain a large portion of our data, but not the entire collection of results.     

Parenting and Beyond: Common Neurocircuits Underlying Parental and Altruistic Caregiving

Interpersonal relationships constitute the foundation on which human society is based. The infant-caregiver bond is the earliest and most influential of these relationships. Driven by evolutionary pressure for survival, parents feel compelled to provide care to their biological offspring. However, compassion for non-kin is also ubiquitous in human societies, motivating individuals to suppress their own self-interests to promote the well-being of non-kin members of the society. We argue that the process of early kinship-selective parental care provides the foundation for non-exclusive altruism via the activation of a general Caregiving System that regulates compassion in any of its forms. We propose a tripartite structure of this system that includes (1) the perception of need in another, (2) a caring motivational or feeling state, and (3) the delivery of a helping response to the individual in need. Findings from human and animal research point to specific neurobiological mechanisms including activation of the insula and the secretion of oxytocin that support the adaptive functioning of this Caregiving System.     

Fostering geospatial thinking in science education through a customisable smartphone application

Enhanced capabilities of modern smartphones offer the potential to design tools that support new forms of teaching and learning. Increased access to mobile‐networked environments and geospatial systems provide opportunities for developing new educational experiences that support a geospatial approach to science, fostering new ways of thinking about science. However, designing effective innovative educational mobile applications remains a challenge. Applications need to be accessible to teachers that are not tech‐savvy as well as those that are, foster active learning pedagogies, enable flexible and creative use, as well as fit within the curriculum. This paper describes a smartphone application developed together with pre‐service science teachers, designed to be customisable by teachers while supporting a geospatial approach to science education. The design process and trial illustrate application use, how it supports a geospatial approach to science education and raises issues around mobile technologies, teacher pedagogies and adoption.     

Perceptions of parental substance use disorders in cross-system collaboration among child welfare,alcohol and other drugs,and dependency court organizations

Cross-system collaboration among child welfare (CW), alcohol and other drugs (AOD), and court organizations shows promise in addressing the many needs of CW-involved families experiencing parental substance use disorders (SUDs). Research has suggested that differing perceptions of parents with SUDs among staff in these organizations may hinder the collaborative process. Using a sequential explanatory mixed-method approach, this study explored staff perceptions of parental SUDs among CW, AOD, and court organizations. Logistic regression analyses indicated that, compared to CW respondents, AOD respondents were: (a) less likely to believe that parents could provide effective parenting; (b) more likely to believe that abstinence should be a criterion for reunification; (c) more likely to agree that parents should receive jail time as a consequence for noncompliance with court orders; and (d) more likely to believe that parents could succeed in treatment. Thematic analyses of these focal areas identified two core themes (focus on the primary client and mandated time frames for permanency), as well as multiple subthemes, that provided a nuanced understanding of differing perceptions on these matters. Suggestions for the development of anticipatory cross-system training and practices and implications for policy evaluation are discussed.     

“I own it,don’t I?” The Rules of Academic Copyright Ownership and You

Abstract

This article delves into a few areas of copyright law that academic authors often overlook: joint author’s rights and the work made for hire doctrine. Scholarly publications produced by university professors often include more than one author. The default copyright laws apply to any such works if there is no specific written agreement to the contrary. Thus, it is important to understand what those default rules are in order to determine whether it is appropriate to deviate from them in an author agreement. Similarly, the work made for hire doctrine would normally apply to make all work produced by professors owned by the university. Luckily, many universities do not wish to own such work and give it back to professors through university statutes and other governing documents. However, it is crucial to understand whether the default rules apply or the university permits professors to negotiate their own author agreements with publishers. Finally, if authors own their own scholarly works, publishers can expect that they will negotiate their rights in the publishing agreements to benefit the terms most favorable to the author. And yet, many faculty members simply sign a standard authorship agreement without asking for concessions on the part of the publisher. Thus, this article empowers professors to exercise their copyright rights to the full extent of the law and to negotiate their author’s agreements to benefit themselves and society as a whole through open access and the use of Creative Commons licenses.
