Attachment Styles and Self‐Image in Turkish Adolescents

The purpose of this article is to examine the attachment styles and the relation of these styles to the self‐image in Turkish adolescents. The study included 378 adolescents (196 females and 182 males) from high schools with different socioeconomic status (SES) who were administered Relationship Scale Questionnaires and Offer Self‐Image Questionnaires. The findings indicate that adolescents from a low SES had significantly low scores on self‐image scales compared with those from high and middle SES. It was found that secure attachment patterns affect social relationships and superior adjustment aspects of self‐image positively. The results of this study show that attachment patterns play an important role in the development of the self‐image, which is a crucial psychological structure gained in adolescence.     

Women,reindeer herding and the Internet: an innovative process in northern Sweden

This research note deals with an innovation initiative involving women, reindeer herding and the Internet. It shows how women reindeer herders from a Swedish Sámi village were a driving force in the development of several innovative, EU-funded projects focusing on information and communications technology. The article shows how the innovation initiative involved a wide range of actors, ascribing stakeholders from civil society important roles besides the public and private sectors. The innovation initiative involved several different strategies. One of these strategies was internationalization – both at the European and worldwide levels. This strategy was employed to prevent rigid political hierarchies blocking the prospects of gaining support from local and regional authorities. Another strategy was the continuous exchange of knowledge between engineers and potential end users, adapting the initiative results to the needs of the local context. As a result, the innovation initiative has produced several kinds of outcomes. It has generated new technology as well as economic and social benefits.     

A note on umvu estimation in the transformed chi-square family

The transformed chi-square family includes many common one-parameter continuous distributions. In that family, we give conditions under which a given function of the mean admits a minimum variance unbiased estimator and an orthogonal expansion for this estimator in terms of the generalized Laguerre polynomials. We show that such expansion is useful for obtaining bounds for the variance and for the study of the asymptotic properties of the unbiased estimators.     

Latino Acculturation and Perceived Educational Achievement: Evidence for a Bidimensional Model of Acculturation among Mexican-American Children

Considerable attention has been paid to the educational fate of Latino children and youths due to mounting evidence that their educational progress has been stagnant. This study investigates the effect of acculturation on perceived educational achievement among Mexican-American children, employing bidimensional acculturation theory to help explain acculturation patterns as related to both ethnic and mainstream identities. Using a sample of 294 Mexican-American children, five acculturation patterns were identified using cluster analysis. We found that the separated group of children had significantly higher educational achievement than the highly assimilated group. The study asserts that the segregated acculturation pattern can be protective for educational achievement of Mexican-American children within ethnically segregated environmental contexts.     

Affective state dependence in a recognition task

Resumen

Se ha elaborado un cuestionario sobre la evaluación del clima emocional (CE). El CE se concibe como un conjunto de emociones salientes y unas representaciones sociales sobre el estado actual y futuro de la sociedad (De Rivera, 1992). Su medida se realiza a través de agregados de respuestas individuales sobre la evaluación del clima social, durante un momento sociopolítico. Se presenta una investigación con estudiantes de 6 países. La escala de CE tiene coeficientes de fiabilidad y validez dimensional transcultural satisfactorios. Encontramos dos dimensiones básicas congruentes con las investigaciones sobre afectividad individual, con relaciones coherentes con afectividad, estrés post-traumático y afrontamiento de traumas colectivos. La no independencia de las respuestas fue contrastada mediante el coeficiente de correlación intraclase. Éste confirmó la interdependencia de respuestas intragrupal, lo) que constituye evidencia estadística de la existencia de un efecto de grupo. Este resultado justifica que se utilice la agregación de respuestas individuales (media por país) como un estimador de un constructo colectivo (CE). La media por país mostró asociación congruente con indicadores macrosociales. Las diferencias inter e intrapaíses en CE muestran la sensibilidad de la escala y su relación con el contexto social.     

A DEA Approach to Measure the Quality-of-Life in the Municipalities of the Canary Islands

The notion of the quality of life has always intrigued economists, sociologists and other researchers in the area of social science. Since the genesis of the definition of Gross Domestic Product (GDP) as a truthful measure of well-being and economic development, other sophisticated methodologies have been proposed in the literature to measure the quality-of-life (QOL) that extend in a multidimensional way this complex concept. Measuring QOL in municipalities consists in finding a set of comparable attributes that can be weighted by some metric in order to construct a synthetic index. Thus, the narrow vision obtained by a single measure as the GDP, in which differences in the QOL cannot be fully analyzed, is overcome. Based upon a refinement of data envelopment analysis (DEA)—the cross-efficiency method, the current paper develops a synthetic QOL index that is based in 19 partial indicators which present the tradeoffs of different dimension for the 87 municipalities of the Canary Islands in Spain. Marginal rates of substitution are calculated to evaluate the tradeoffs on QOL dimensions. A method is also proposed to determine the scores chart of each municipality which can be used as a tool to policy makers in order to establish a program of improving the ranking position of the municipality identifying the critical QOL factors.     

Comparison op some two sample tests for equality of variances

The F-test, F max-test and Bartlett's test are compared on the basis of power for the purpose of testing the equality of variances in two normal populations. The power of each test is expressed as a linear combination of F-probabilities. Bartlett's test is noted to be unbiased, UMPU, consistent against all alterna¬tives and the test which yields minimum length confidence intervals on the ratio of the variancesλ=σ₁ ² /σ² ₂ The two samples Bartlett critical values, although not recognized as such, are found in the works of other authors. Tables of the powers of each test are given for various values of λ, levels of significance a and the respective sample sizes, n₁ and n₂.     

Marginally restricted D-optimal designs for correlated observations

Two practical degrees of complexity may arise when designing an experiment for a model of a real life case. First, some explanatory variables may not be under the control of the practitioner. Secondly, the responses may be correlated. In this paper three real life cases in this situation are considered. Different covariance structures are studied and some designs are computed adapting the theory of marginally restricted designs for correlated observations. An exchange algorithm given by Brimkulov's algorithm is also adapted to marginally restricted D–optimality and it is applied to a complex situation.     

Teaching Literature to Highlight Social Policy Issues

Abstract

Graduate social work education can be enhanced through extensive and appropriate use of relevant literary works. This paper describes an elective course for second-year graduate social work students in which twentieth-century novels were used to highlight social policy issues. The paper deals with the relationships between art and social realities and the usefulness of literature for social policy analysis. A detailed account of this course and its evaluation is presented as well as its potential for replication.
