Testing for universality of Mendeley readership distributions

Altmetrics promise useful support for assessing the impact of scientific works, including beyond the scholarly community and with very limited citation windows. Unfortunately, altmetrics scores are currently available only for recent articles and cannot be used as covariates in predicting long term impact of publications. However, the study of their statistical properties is a subject of evident interest to scientometricians. Applying the same approaches used in the literature to assess the universality of citation distributions, the intention here is to test whether the universal distribution also holds for Mendeley readerships. Results of the analysis carried out on a sample of publications randomly extracted from the Web of Science confirm that readerships seem to share similar shapes across fields and can be rescaled to a common and universal form. Such rescaling results as not particularly effective on the right tails. In other regions, rescaling causes a good collapse of field specific distributions, even for very recent publications.     

Are all citations worth the same? Valuing citations by the value of the citing items

Bibliometricians have long recurred to citation counts to measure the impact of publications on the advancement of science. However, since the earliest days of the field, some scholars have questioned whether all citations should be worth the same, and have gone on to weight them by a variety of factors. However sophisticated the operationalization of the measures, the methodologies used in weighting citations still present limits in their underlying assumptions. This work takes an alternative approach to resolving the underlying problem: the proposal is to value citations by the impact of the citing articles, regardless of the length of their reference list. As well as conceptualizing a new indicator of impact, the work illustrates its application to the 2004–2012 Italian scientific production indexed in the WoS. The proposed impact indicator is highly correlated to the traditional citation count, however the shifts observed between the two measures are frequent and the number of outliers not negligible. Moreover, the new indicator shows greater “sensitivity” when used to identify the highly-cited papers.     

The development and validation of a scale measuring teacher autonomous behaviour

In the current study a multi‐dimensional scale that measures teacher autonomous behaviour is presented. The scale is applicable across the following educational sectors: primary education, secondary education and vocational education. Based on an elaborate literature study, four theoretically relevant dimensions of teacher autonomous behaviour were derived. Psychometric characteristics of the instrument (note that the terms ‘scale’ and ‘instrument’ are used interchangeably in this article) were tested among a sample of Dutch teachers working in primary, secondary and vocational education (N = 1111). The validity of our instrument was tested in several ways. First, by performing confirmatory factor analysis, we tested the factorial structure, which confirmed the hypothesised four dimensions: (1) primary work processes in the class; (2) curriculum implementation; (3) participation in decision making at school; (4) professional development. Thereafter, we calculated the scale's reliability, which appeared to be excellent. In addition, we tested for measurement invariance by cross‐validating the study in the educational sectors mentioned above. Also, the convergent, divergent and predictive validity was investigated. Teacher autonomy appeared to predict workplace learning, more specifically experimenting, reflecting and school development. Finally, we investigated whether transformational leadership can facilitate teacher autonomy, which appeared to be the case. The results empirically confirm the four dimensions of teacher autonomous behaviour, which we derived from theory, and offer solid proof of the psychometric properties of our instrument. The instrument can be used by school leaders and policy makers to monitor autonomous behaviour. More generally, the development and use of this instrument helps us understand teacher autonomous behaviour and teacher professionalism.     

Integrated schools and intergroup relations in Northern Ireland: the importance of parents

Background: Integrated schools were established in Northern Ireland in the early 1980s. With an explicit intention to build better relations between Catholics and Protestants, it has an intuitive appeal in a society which has long experienced sectarian division. Whilst the sector has attracted considerable research, less is understood about how parents’ perceive the approach adopted by schools to build intergroup relations.

Purpose: The present article seeks to address the gap in the literature by exploring parents’ views of integrated education. Drawing on theories of intergroup contact, the paper seeks specifically to explore how parents and head teachers perceive and negotiate the approach that the schools adopt to build intergroup relations.

Method: In an attempt to probe the deeper meanings that participants attach to integrated education, a qualitative research approach was adopted; semi-structured interviews were carried out with 17 parents and 2 head teachers in two integrated primary schools.

Findings: Through the data analyses, three main aspects were evident. Firstly, the study reveals something of the relational dynamic between head teachers and parents and the significance of this relationship for determining how intergroup relations are pursued in integrated schools. Secondly, it highlights the nebulous nature of identity salience and the practical challenges of making identity salient within mixed identity contexts. Finally, the study suggests the value of qualitative approaches for exploring intergroup contact initiatives.

Conclusions: Overall, the paper demonstrates the inherent challenges of establishing an integrated school where good relations will be developed when multiple interpretations of what constitutes an appropriate response to difference and diversity prevails.     

Self‐Assessment in Art Education through a Visual Rubric

A tool for self assessment in secondary art education was developed and tested. The tool includes rubrics for assessing production and reception activities in art education and consists of visual and text rubrics. The criteria in the rubrics are based on the Common European Framework of Reference for Visual Literacy which was developed by The European Network of Visual Literacy (ENViL). The way teachers and students use the rubrics, whether they consider them helpful and to what extent students’ self‐assessments are in line with teacher assessments was studied. It was concluded that teachers work with the rubrics intensively and both students and teachers appreciate its visual form. However, it was found that the agreement between teachers and students about the students’ scores was moderate and needed to improve. The results show that it is untrue that students, or boys in particular, overestimate their own performance in art education. The current study contributes to the development of feasible and valid assessment criteria and instruments in secondary art education.     

Thirteen-month-olds rely on shared labels and shape similarity for inductive inferences

This study examined the influence of shape similarity and labels on 13-month-olds' inductive inferences. In 3 experiments, 123 infants were presented with novel target objects with or without a nonvisible property, followed by test objects that varied in shape similarity. When objects were not labeled, infants generalized the nonvisible property to high-similarity objects (Experiment 1). When objects were labeled with the same noun, infants generalized the nonvisible property to high- and low-similarity objects (Experiment 2). Finally, when objects were labeled with different nouns, infants generalized the nonvisible property to high-similarity objects (Experiment 3). Thus, infants who are beginning to acquire productive language rely on shared shape similarity and shared names to guide their inductive inferences.     

Troubling identities: teacher education students' constructions of class and ethnicity

Working with diverse student populations productively depends on teachers and teacher educators recognizing and valuing difference. Too often, in teacher education programs, when markers of identity such as gender, ethnicity, ‘race’, or social class are examined, the focus is on developing student teachers' understandings of how these discourses shape learner identities and rarely on how these also shape teachers' identities. This article reports on a research project that explored how student teachers understand ethnicity and socio‐economic status. In a preliminary stage of the research, we asked eight Year 3 teacher education students who had attended mainly Anglo‐Australian, middle class schools as students and as student teachers, to explore their own ethnic and classed identities. The complexities of identity are foregrounded in both the assumptions we made in selecting particular students for the project and in the ways they constructed their own identities around ethnicity and social class. In this article we draw on these findings to interrogate how categories of identity are fluid, shifting and ongoing processes of negotiation, troubling and complex. We also consider the implications for teacher education.     

Discriminative stimuli that follow the absence of reinforcement are preferred by pigeons over those that follow reinforcement

Clement, Feltus, Kaiser, and Zentall (2000) found that when pigeons have to work to obtain a discriminative stimulus that is followed by reinforcement, they prefer a discriminative stimulus that requires greater effort over one that requires less effort. The authors suggested that such a preference results from the greater change in hedonic value that occurs between the more aversive event and the onset of the stimulus that signals reinforcement, a contrast effect. It was hypothesized that any stimulus that follows a relatively more aversive event would be preferred over a stimulus that follows a relatively less aversive event. In the present experiment, the authors tested the counterintuitive prediction of that theory, that pigeons should prefer a discriminative stimulus that follows the absence of reinforcement over a discriminative stimulus that follows reinforcement. Results supported the theory.
