The Effect of Gender and Minority Status on Salary in Private and Public ARL Libraries

The purpose of this study was to identify pay disparities within gender and race using private and public Association of Research Libraries (ARL) libraries as a lens. In this study, 44 ARL libraries participated, leading to 1099 usable responses to our survey. The findings indicate that race and gender pay disparities are larger at private libraries than at public libraries. However, disparity levels at both public and private ARL libraries are smaller than the national averages for all professions and continue to shrink.     

Studies on the Formation of Perceptually Based Basic-Level Categories in Young Infants

A series of experiments examined the abilities of 3- and 4-month-old infants to form categorical representations to exemplars of natural kinds–cats and horses. These experiments also permitted assessment of the relative exclusivity of these representations—the extent to which they exclude exemplars from contrasting basic-level categories from the same superordinate category. We found that categorical representations could be formed for horses that excluded cats, zebras, and giraffes, and for cats that excluded horses and tigers but not female lions. Lions were, however, excluded from the representations of cats in 6- and 7-month-old infants. Evidence was also obtained for 2 a priori preferences for members of one category over another. The discussion examined the roles of similarity between the exemplars of the contrasting categories and those of the tested category on estimates of exclusivity and of spontaneous preferences on the formation and exclusivity of categorical representations.     

Designing an instructional game: reflections on ‘Quest for Independence’

Certain design opportunities stretch the boundaries of established procedure and when members of a working party on ‘After Care’ came to us seeking a computer component for a multimedia package we were confronted with just such a challenge. Faced with the unusual instructional goal of training indpendent-living skills, an unusual target population of low-literacy youth, and hardware limitations of lowest-common-denominator microcomputers, naturally, we developed a computer game. Using a cognitive approach, we developed ‘Quest for Independence’, a computer-based simulation game to develop independent-living skills. In this paper we discuss the approach, the resulting game and the current status.     

K-8 Teachers’ Overall and Gender-Specific Beliefs About Mathematical Aptitude

Teachers’ beliefs play a significant role in students’ academic attainment and career choices. Despite comparable attainment levels between genders, persistent stereotypes and beliefs that certain disciplines require innate ability and that men and women have different ability levels impede students’ academic career paths. In this study, we examined the prevalence of US mathematics teachers’ explicit general and gender-specific beliefs about mathematical ability and identified which teacher characteristics were associated with these beliefs. An analysis of data from 382 K-8 teachers in the USA indicated that overall, teachers disagreed with the idea that general and gender-specific mathematical ability is innate and agreed with the idea that hard work and dedication are required for success in mathematics. However, our findings indicate that those who believed mathematics requires brilliance also tended to think girls lacked this ability. We also found that teachers who were teaching mathematics to 11- to 14-year-old students seemed to believe that mathematics requires innate ability compared with teachers who were teaching mathematics to 5- to 10-year-old students. In addition, more experienced teachers and teachers who worked with special education students seemed to believe less in the role of hard work in success in mathematics, which could have serious consequences for shaping their students’ beliefs about their academic self-concept and future career-related decisions.

     

In Defense of Core Competencies,Quantitative Change,and Continuity

J. Kagan (2008) urges contemporary developmentalists to (a) be cautious when attributing conceptual knowledge to infants based on looking‐time performance, (b) constrain their interpretation of infant performance with multiple methodologies, and (c) reconsider the possibility that qualitative development may be the path by which perceptual infants become conceptual adults. This commentary outlines an account of conceptual development that adheres to two of the three Kagan provisos. It is (a) circumspect in the core competencies attributed to infants and (b) grounded in convergent measures including looking time, event‐related potentials, computational modeling, and eye tracking, but (c) maintains that the transition from the perceptually based category representations of infants to the knowledge‐rich concepts of adult is a continuous developmental process marked by quantitative change.

The Self‐Reference Effect on Memory in Early Childhood

The self‐reference effect in memory is the advantage for information encoded about self, relative to other people. The early development of this effect was explored here using a concrete encoding paradigm. Trials comprised presentation of a self‐ or other‐image paired with a concrete object. In Study 1, 4‐ to 6‐year‐old children (N = 53) were asked in each trial whether the child pictured would like the object. Recognition memory showed an advantage for self‐paired objects. Study 2 (N = 55) replicated this finding in source memory. In Study 3 (N = 56), participants simply indicated object location. Again, recognition and source memory showed an advantage for self‐paired items. These findings are discussed with reference to mechanisms that ensure information of potential self‐relevance is reliably encoded.     

A Nonparametric Approach to Estimate Classification Accuracy and Consistency

When cut scores for classifications occur on the total score scale, popular methods for estimating classification accuracy (CA) and classification consistency (CC) require assumptions about a parametric form of the test scores or about a parametric response model, such as item response theory (IRT). This article develops an approach to estimate CA and CC nonparametrically by replacing the role of the parametric IRT model in Lee's classification indices with a modified version of Ramsay's kernel‐smoothed item response functions. The performance of the nonparametric CA and CC indices are tested in simulation studies in various conditions with different generating IRT models, test lengths, and ability distributions. The nonparametric approach to CA often outperforms Lee's method and Livingston and Lewis's method, showing robustness to nonnormality in the simulated ability. The nonparametric CC index performs similarly to Lee's method and outperforms Livingston and Lewis's method when the ability distributions are nonnormal.     

Mapping the field of Higher Education Research using PhD examination reports

The PhD is the highest formal qualification and signifies a scholar’s rite of passage as a legitimate contributor of new knowledge in a field. Examiner reports make claims about what is legitimate in a thesis and what is not and thus articulate the organising principles through which participation in a field is measured. The authors analysed 39 examiners’ reports on 13 PhDs produced over a five-year period by scholars from the Higher Education Research doctoral studies programme at Rhodes University in South Africa. Drawing on aspects of Karl Maton’s Legitimation Code Theory (LCT), this study uses the dimensions of LCT:Specialisation and LCT:Semantics to explore what kinds of knowledge, skills and procedures and what kinds of knowers are validated in the field of Higher Education Research through the examination process. The study found that despite concerns in the literature about the a-theoretical nature of the Higher Education Studies field, examiners valued high-level theoretical and meta-theoretical engagement as well as methodological rigour. In addition, examiners prized the ability to demonstrate a strong ideological position, to use a clear doctoral voice, and to recognise the axiological drive of the field. The analysis showed that examiners were interested in strong contextualisation of the problem-spaces in higher education in South Africa but also commented positively on candidates’ ability to move from troubling an issue within its context to being able to abstract findings so as to contribute to the field as a whole.
