Impact maturity times and citation time windows: The 2-year maximum journal impact factor

Journal metrics are employed for the assessment of scientific scholar journals from a general bibliometric perspective. In this context, the Thomson Reuters journal impact factors (JIFs) are the citation-based indicators most used. The 2-year journal impact factor (2-JIF) counts citations to one and two year old articles, while the 5-year journal impact factor (5-JIF) counts citations from one to five year old articles. Nevertheless, these indicators are not comparable among fields of science for two reasons: (i) each field has a different impact maturity time, and (ii) because of systematic differences in publication and citation behavior across disciplines. In fact, the 5-JIF firstly appeared in the Journal Citation Reports (JCR) in 2007 with the purpose of making more comparable impacts in fields in which impact matures slowly. However, there is not an optimal fixed impact maturity time valid for all the fields. In some of them two years provides a good performance whereas in others three or more years are necessary. Therefore, there is a problem when comparing a journal from a field in which impact matures slowly with a journal from a field in which impact matures rapidly. In this work, we propose the 2-year maximum journal impact factor (2M-JIF), a new impact indicator that considers the 2-year rolling citation time window of maximum impact instead of the previous 2-year time window. Finally, an empirical application comparing 2-JIF, 5-JIF, and 2M-JIF shows that the maximum rolling target window reduces the between-group variance with respect to the within-group variance in a random sample of about six hundred journals from eight different fields.     

Statistical Models and Inference for the True Equating Transformation in the Context of Local Equating

Based on Lord's criterion of equity of equating, van der Linden (this issue) revisits the so‐called local equating method and offers alternative as well as new thoughts on several topics including the types of transformations, symmetry, reliability, and population invariance appropriate for equating. A remarkable aspect is to define equating as a standard statistical inference problem in which the true equating transformation is the parameter of interest that has to be estimated and assessed as any standard evaluation of an estimator of an unknown parameter in statistics. We believe that putting equating methods in a general statistical model framework would be an interesting and useful next step in the area. van der Linden's conceptual article on equating is certainly an important contribution to this task.     

Michael Pressley's Contributions to the History and Future of Strategies Research

The recently fashionable theories of positive psychology have educational ramifications at virtually every level of engagement, culminating in the model of positive education. In this critical review, I scrutinize positive education as a potential theory in educational psychology. Special attention is given to conceptual controversies and suggested educational interventions. Positive psychologists have yet to explore in detail the school as a positive institution. They have written at length, however, about such positive personal traits as moral virtue and resiliency, and about positive emotions both as embodied in experiences of classroom “flow” and as facilitators of students’ personal resources. Because the empirical evidence concerning these positive factors remains partly mixed or tentative, and because most of them had a home in other theoretical frameworks before the advent of positive psychology, searching questions remain about the effectiveness and originality of positive education. This article addresses some of those questions.     

Foundations of Laic Moral Education in Spain

This article studies the foundations of laic moral education in Spain. Some aspects of laic moral education can also be found in other nations, including the emergence of the laic man or the need for an educating State; other aspects of laic moral education, however, are peculiar to the Spanish case, such as the influence of Krausoinstitutionism and the programmes of 1931 Republicanism. This analysis of laic moral education centres on the bipolarity of traditionalism/liberalism. The article takes 1857 as its starting point, a date that is significant for the birth of laic morality and the Spanish education system. The article’s end point is 1936, on the threshold of the Civil War. This bipolarity of traditional/liberal is in combination, on the one hand, with the demands of Krausoinstitutionism for an independent morality and neutrality in instruction as tools for the attainment of a moral ideal of preparing men and, on the other hand, the Republican vindication of an autonomous morality and school laicism as key to the preparation of citizens, as well as with the demand for a civil morality fostered by an educating State.     

Political decision-making in socialist education: a Hungarian case study (1958–1960)

The subject of this article is a definite shift in socialist pedagogy: the implementation of polytechnic education in the late 1950s. First, the Soviet model is presented, then the analysis of its Hungarian introduction shows the decision-making process thoroughly, from the first steps in February 1958 to the publication of the ‘Principles’ in September 1960, which affected subsequent discourse about the so-called ‘school-reform’. The study is based on the reports of the Hungarian Socialist Workers’ Party archives, mainly the files of the Political Committee, because this body designed and determined the characteristics of the new era in Hungarian education. Silence dominated the afterlife of the reform after 1965 – in retrospect, it was a failure – and the situation has not changed since. Although the archives are now open, the actors in the decision-making process, and their different interests, have not yet been investigated by scholars.     

¿Han sido seleccionados o se han acostumbrado? Ideas de estudiantes de biología sobre la selección natural y consistencia entre ellas

Resumen

Estudiantes universitarios de Biología, ante problemas de respuesta abierta sobre la selección natural, utilizan, en porcentajes alarmantes, interpretaciones que consideran la adaptación como cambios heredables en los individuos. Se encontró un cierto grado de consistencia entre las respuestas de cada sujeto a los problemas en diferentes contextos; pero hay también casos en que una persona empleó esquemas conceptuales diferentes. Se sugiere que una de las condiciones para promover el cambio conceptual es que los profesores tengan en cuenta las ideas de los estudiantes.     

La expresión facial en los ciegos congénitos

Resumen

El presente informe analiza la expresión emocional de los ciegos congénitos mediante una codificación muscular de los movimientos faciales. Esta expresión, de carácter más involuntario, es semejante a la de los videntes. En cambio, los sujetos invidentes tienen una expresividad menor y menos diferenciada en las poses voluntarias. Los resultados, que confirman los hallazgos de autores anteriores, apoyan la existencia de dos fuentes de información en el desarrollo emocional: una de naturaleza genética, que explicaría las semejanzas en la expresión emocional o involuntaria, y otra ambiental, que daría cuenta de las diferencias en la expresión voluntaria. Por último, se plantean las consecuencias de este trabajo para las distintas disciplinas psicológicas.     

Estimulación precoz: una experiencia en una guardería de educación especial

RESUMEN

Se describe un programa de estimulación precoz llevado a cabo en un centro de educación especial, programa que se marcó dos objetivos principales: ofrecer al niño un ambiente rico en estímulos y mejorar la relación afectiva de los padres. El diagnóstico se hace a través de un enfoque multidisciplinar y se trabaja en cuatro áreas: desarrollo personal, control motor grueso, control motor fino y lenguaje. Es muy importante integrar a los padres en el programa educativo, ya que son los principales agentes educativos. En este sentido se trabaja a nivel tanto informativo (de forma individual y con sesiones programadas en la Escuela de Padres) como formativo (asesoramiento familiar individual).     

La percepción de contingencias y el conocimiento social temprano

Resumen

La «hipótesis del juego» («Game hipothesis»), propuesta por Watson en 1972, establece que la percepción de relaciones contingentes entre acciones y estímulos ambientales es, con independencia de la naturaleza de tales estímulos, un determinante poderoso del desarrollo social del bebé. Se investiga la posible influencia de la naturaleza de los estímulos contingentes mediante el uso de estímulos «sociales» (emisiones lingüísticas) y «no sociales» (música) en una situación de percepción de contingencias, que se estableció para 6 bebés, con una edad media de 3 meses y 2 días. Los resultados demuestran que existen diferencias entre los estímulos sociales y no-sociales tanto en lo referente a los patrones de adquisición de las «operantes» o «respuestas circulares» ante las contingencias, como en las respuestas emocionales que acompañaban a los procesos de adquisición y extinción. Estas diferencias sugieren la necesidad de reconocer la importancia de la naturaleza de los estímulos contingentes en la interpretación del papel social de los procesos de percepción de contingencias.
