A second look at Egghe’s universal IR surface and a simple derivation of a complete set of universal IR evaluation points

Egghe’s three papers regarding the universal IR surface (2004, 2007, 2008) clearly represent an original and significant contribution to the IR evaluation literature. However, Egghe’s attempt to find a complete set of universal IR evaluation points (P,R,F,M) fell short of his goal: his universal IR surface equation did not suffice in and of itself, and his continuous extension argument was insufficient to find all the remaining points (quadruples). Egghe found only two extra universal IR evaluation points, (1,1,0,0) and (0,0,1,1), but it turns out that a total of 15 additional, valid, universal IR evaluation points exist. The gap first appeared in Egghe’s earliest paper and was carried into subsequent papers. The mathematical method used here for finding the additional universal IR evaluation points involves defining the relevance metrics P,R,F,M in terms of the Swets variables a,b,c,d. Then the maximum possible number of additional quadruples is deduced, and finally, all the invalid quadruples are eliminated so that only the valid, universal IR points remain. Six of these points may be interpreted as being continuous extensions of the universal IR surface, while the other nine points may be interpreted as being “off the universal IR surface.” This completely solves the problem of finding the maximum range possible of universal IR evaluation points.     

Munchausen by Proxy in an international context

OBJECTIVE: The professional literature on Munchausen by Proxy (MBP) abuse consists of more than 400 articles, chapters, and books. Most have come from a handful of English-speaking industrialized countries. Our aims were to establish the extent to which published work about MBP has emerged from outside these countries, and to determine the characteristics of any reported cases. METHOD: Numerous health care computer databases were queried, and the results supplemented by materials accumulated less formally. RESULTS: We identified 59 articles from 24 countries describing at least 122 cases in 9 different languages. Among cases in which the information was available, the mother was the sole perpetrator in 86%, the victim was aged between 3 years and 13 years in 52%, and the victim was male in 54%. The presentations of MBP appear to be similar across the world with the exception of induced apnea, which emerged as notably uncommon in this review. An extensive table presents the characteristics of each case. CONCLUSIONS: MBP clearly is not a phenomenon unique to Western or highly medicalized societies. This form of abuse is being increasingly recognized and reported throughout the world. The literature from the US, Canada, UK, Australia, and New Zealand often presupposes access to resources, such as subspecialists and social service agencies, that may be seriously constrained in other countries. The contributions of professionals elsewhere will be vital in ensuring that the efforts in English-speaking industrialized settings to develop standards of care encompass an international perspective.     

About Face: The Rebirth of the Portrait Gallery in the Twenty‐first Century

Abstract Given the Victorian origins of the idea of a national portrait gallery, how relevant are such institutions today? The rebirth of the National Portrait Gallery in Washington, D.C. has involved a reinvestigation of notions of greatness, national identity, and the ongoing vitality of portraiture as an artistic form. Who should be deemed crucial to the telling of our national history? The evolution of thinking in our own day about the nature of national identity has undergone a dramatic shift. We have made decisions that might curl a Victorian's toes.     

Validité des instruments de décision pour l'évaluation des enseignants?

A review of the literature shows that the use of teacher evaluation in public education is widespread. This seems paradoxical when one considers the amount of criticism levied at them by a various groups. The present study was designed in order to deal with the problems of validity and reliability of teacher evaluation instruments planned for the purpose of teachers' promotion or for awarding merit pay. Based upon a review of the literature and school inspectors' judgements, a teacher evaluation instrument including 25 items has been constructed. The instrument has been tested by five school inspectors and 180 school principals. Following their judgements and the factor analysis run upon the data, a face validity and a content validity of the developed instrument emerged. However, conclusions concerning the reliability of the instrument have to be treated with caution. The use of an instrument of this type is justified only for making preliminary decisions as to the eligibility of teachers for further consideration for promotion or for merit pay. L'analyse de la littérature professionnelle montre l'utilisation croissante dans les établissements publics des instruments d'évaluation des enseignants. Ceci parait paradoxal si l'on tient compte des critiques importantes formulées à leur encontre par des groupes différents. La présente étude traite des problèmes de validitéet de fiabilitédes instruments d'évaluation des enseignants pour les décisions de promotion et de rémunération ''de mérite''. Se fondant sur la littérature professionnelle et sur les appréciations formulées par les inspecteurs scolaires, elle a élaboré un instrument représentatif d'évaluation des enseignants comportant 25 éléments. L'instrument a été testé auprès de 5 inspecteurs et de 180 directeurs d'école. Les résultats révèlent que cet instrument possède une validitéde contenu établie sur la littérature professionnelle, sur l'appréciation des inspecteurs scolaires et sur les résultats d'une analyse de facteurs fondée sur les réponses des directeurs d'école au questionnaire proposé. Toutefois, en ce qui concerne la fiabilité, les conclusions sont plus nuancées. L'utilisation d'instruments de ce type semble uniquement efficace pour la détermination préliminaire de ceux qui au sein des enseignants auraient droit ensuite à un examen plus précis de leurs mérites en vue de promotion ou de rémunérations. El análisis de la literatura profesional evidencia el uso creciente en los establecimientos públicos de instrumentos de evaluación de los profesores. Esto podría parecer paradójico si se tienen en cuenta las críticas importantes formuladas por diferentes grupos. El presente estudio trata de los problemas de validez y de fiabilidad de los instrumentsos de evaluación de los profesores para las decisiones de promoción y de remuneración ''del mérito''. Tomando como base la literatura profesional y las apreciaciones formuladas por los inspectores escolares, se ha elaborado un instrumento representativo de la evaluación de los profesores que comporta 25 elementos. El instrumento se sometióa prueba con 5 inspectores y 180 directores de escuela. Los resultados revelan que este instrumento representativo posee una validez de contenido establecida a partir de la literatura profesional, de la apreciación de los inspectores escolares y de los resultados de un análisis de factores que se fundamenta en las respuestas al cuestionario de directores de escuela. Sin embargo, en lo que se refiere a la fiabilidad de contenido, las conclusiones no son tan definidas. El uso de instrumentos de este tipo parece únicamente eficaz para la determinación preliminar de aquellos profesores que podrian tener derecho en una fase posterior, a pasar un examen más preciso de sus méritos para una promoción o remuneración. Sin embargo, dicho grupo de profesores una vez identificado, el instrumento no parece ser lo suficientemente fiable para la decisión de una promoción y convendría desarrollar enfoques complementarios. Ein Überblick über die Fachliteratur zeigt, dass sich die Verwendung Lehrerbewertungen immer mehr verbreitet, obwohl es paradoxalerweise von verschiedenen Gruppen stark kritisiert wird. Die vorliegende Studie beschäftigt sich mit den Problemen der Gültgkeit und Zuverlässigkeit von den Lehrerbewertungsmitteln, in Bezug auf die Beförderungsentscheidungen und auf die Leistungsentlohnungen. Sie hat, gestützt auf die Fachliteratur und auf die Ansichten der Schulraten, einen Bewertungssystem der Lehrer in 25 Punkten entworfen. Dieses Bewertungssystem wurde von 25 Schulraten und von 180 Schuldirektoren geprüft. Ihre Ansichten, sowie die Faktorenanalyse der Daten, bestätigen die Gültigkeit dieses Instrumentes. Die Benutzung eines Instrumentes dieser Art sollte zu einer ersten Entscheidung führen, dessen Inhalt nur die Berechtigung der Lehrer zur Beförderung, zur Leistungsentlohnung und zur weitere Untersuchung beinflussen sollte.     

Infant Temperament: Stability by Age,Gender, Birth Order,Term Status,and Socioeconomic Status

Two complementary studies focused on stability of infant temperament across the 1st year and considered infant age, gender, birth order, term status, and socioeconomic status (SES) as moderators. Study 1 consisted of 73 mothers of firstborn term girls and boys queried at 2, 5, and 13 months of age. Study 2 consisted of 335 mothers of infants of different gender, birth order, term status, and SES queried at 6 and 12 months. Consistent positive and negative affectivity factors emerged at all time points across both studies. Infant temperament proved stable and robust across gender, birth order, term status, and SES. Stability coefficients for temperament factors and scales were medium to large for shorter (< 9 months) interassessment intervals and small to medium for longer (> 10 months) intervals.     

Neural Correlates of Self and Its Interaction With Memory in Healthy Adolescents

Adolescence is marked by the development of personal identity and is associated with structural and functional changes in brain regions associated with Self processing. Yet, little is known about the neural correlates of self‐reference processing and self‐reference effect in adolescents. This functional magnetic resonance imaging study consists of a self‐reference paradigm followed by a recognition test proposed to 30 healthy adolescents aged 13–18 years old. Results showed that the rostral anterior cingulate cortex is specifically involved in self‐reference processing and that this specialization develops gradually from 13 to 18 years old. The self‐reference effect is associated with increased brain activation changes during encoding, suggesting that the beneficial effect of Self on memory may occur at encoding of self‐referential information, rather than at retrieval.     

Arts Journalism And Its Packaging In France,Germany, The Netherlands And The United States, 1955–2005

In the second half of the twentieth century, the volume, content and appearance of arts journalism in Western daily newspapers have changed significantly in accordance with wider transformations in the arts and journalism. Previous studies have focused on (1) which culture receives attention, (2) the way culture gets attention, and (3) economic pressures underlying transformations. In this article we aim to bring these strands together by analyzing how changes in the packaging of arts journalism have evolved in relation to the cultural content which is discussed and the volume of (cultural) advertising that is featured in newspapers. We conduct a content analysis of the coverage given to both “highbrow” and “popular” art forms in French, German, Dutch and US elite newspapers for four sample years: 1955, 1975, 1995 and 2005. The results show that newspapers all seem to converge into a balance between news reporting and reviewing. We find evidence for an increased catering for the needs and interests of audiences in some aspects (e.g. more popular culture) but not in others (e.g. no more human interest). Finally, most newspapers show an increase in cultural advertising, although the European newspapers in our sample contain much less advertising than the American ones. A stronger presence of advertising is positively related to both a lifestyle orientation of newspapers and a focus on popular culture.
