Actividad prefrontal y alcoholismo de fin de semana en jóvenes

Antecedentes. El consumo elevado de alcohol por parte de jovenes durante el fin de semana se esta convirtiendo en un problema social y familiar importante pero tambien en un problema de salud considerable. El consumo abusivo ocasiona danos en el cerebro pero con diferente distribucion, ya que la corteza prefrontal (CP) es una de las regiones que resulta mas afectada. Objetivos. Hay numerosos estudios sobre los efectos del consumo cronico de alcohol. Nuestro objetivo es determinar los deficits neuropsicologicos en la actividad prefrontal ocasionados por el consumo abusivo de alcohol de manera intermitente en adolescentes. Metodo. Se realizo una evaluacion neuropsicologica a los sujetos para valorar su rendimiento en diversas tareas que implican a la CP. Participaron 62 sujetos (edad media 18.821.099) distribuidos en tres grupos: 1) Jovenes que consumian alcohol de manera abusiva durante los fines de semana (ALE); 2) Jovenes que consumian mas moderadamente durante los fines de semana (ALM); y 3) Jovenes que no consumian alcohol (CTR). Resultados y Conclusiones. Los resultados indican que el consumo abusivo intermitente de alcohol por parte de jovenes, tanto de manera elevada como moderada, provoca un peor rendimiento en tareas neuropsicologicas como Digitos, Corsi o Stroop, las cuales dependen de un correcto funcionamiento de la CP. Nuestros resultados apoyan la idea de que este patron de consumo provoca un deterioro neurocognitivo y neuroconductual similar en muchos aspectos al observado en bebedores cronicos. Ademas, el consumo abusivo de fin de semana por parte de adolescentes y jovenes incrementa el riesgo de desarrollar dependencia alcoholica y otras patologias en etapas posteriores de la vida.
ORGANIZATIONAL CLIMATE AND EMOTIONAL INTELLIGENCE: AN APPRECIATIVE INQUIRY INTO A “LEADERFUL” COMMUNITY COLLEGE

ABSTRACT In an era of unprecedented challenges and rapid change, community colleges need effective leadership that brings out the best in people, organizations, and communities. This qualitative study was based on interpretive research using appreciative inquiry (AI). AI is based on social constructivist theory and is a collaborative and highly participative approach to inquiry. AI is action research that is a radically affirmative approach searching for the best in people and their organizations. It involves systematic discovery of what gives a system life when it is most effective. In this study the participants engaged in appreciative interviews using provocative positive questions on the topic of emotional intelligence and organizational climate. Both emotional intelligence (EI) and appreciative inquiry are evolving constructs. By integrating the technique (appreciative inquiry) with the topic (emotional intelligence), the question of how emotionally-intelligent leadership affects organizational climate was explored. This study addresses potentially useful questions about the characteristics of emotional intelligence and its possible implications for affecting organizational climate.

A tabloid mind? Professional values and organizational pressures as explanations of tabloid journalism

Tabloidization of news and its potential threat to democracy is a recurring issue in debates among scholars and journalists. Most research focuses on measuring either content or the effects of tabloid-style content and often leaves the antecedents of the content as a ‘black box’. This study compares tabloid journalists to other journalists based on a survey of Danish journalists (N = 1550). It shows that tabloid journalists in many regards hold professional values that differ from the values of other journalists and that they experience different pressures from the organization in which they work. In their journalistic style tabloid journalists emphasize personalization and sensationalist news values more and relevance news values less than other journalists. Finally, tabloid-style journalism is to some extent driven by profit orientation in journalists as well as in their organizations. However, the study also shows that journalists’ adherence to the role as public mobilizer is positively related to personalization, which implies that tabloidization might carry benefits and not only threats to democracy.
Influence of Pulse Reverse Plating on the Properties of Ni-Fe Thin Films

NiFe thin films deposited by pulse reverse (PR) electrodeposition are promising candidates for the next generation of core magnetic material to be used in magnetic components operating at high switching frequency. The influence of PR electroplating on the structural, magnetic and electrical properties of NiFe is assessed by means of a design of experiment (DOE). Results are compared to NiFe alloys produced by direct current (dc) deposition from an identical electrolyte. The PR samples exhibit an increase in resistivity and relative permeability by a factor of 2 and 1.5, respectively, in comparison to the dc samples. The coercivity and saturation flux density of the PR samples are reduced by 37% and 5%, respectively.
Force and time control in the production of rhythmic movement sequences in Parkinson's disease

This study investigated force and time control in rhythm production in Parkinson's disease. Patients and age‐matched controls reproduced rhythms consisting of equal (600 ms) or alternating (400 and 800 ms) intervals, produced with equal (12 N) or alternating (8 and 16 N) forces, under paced (synchronization) and unpaced (continuation) conditions. Performance was assessed in terms of accuracy and variability. Reproduction of force amplitudes was less accurate in patients than in controls when either time or force alternated but did not deteriorate further when force and time alternated. In contrast, interval timing was least accurate in patients compared with controls when rhythm alternated on both dimensions. The ratio between alternating force levels was better maintained by controls than by patients, without influence of timing requirements in either group. In contrast, the ratio between alternating intervals was relatively preserved in patients when force remained constant but was severely compromised when force alternated. Timing variability was greater in the patient group, especially in the more affected side, but there was no difference in timing variability between groups as a function of rhythm, and there were no differences between groups in variability of force. The results show that force and time control in patients are affected in different ways. We interpret the preserved timing of rhythms with alternation on one dimension as evidence of intact ability to organize movements in a sequence. The data are compatible with a basal ganglia role in the coregulation of time and force, but do not support a general timing function of the basal ganglia.
Hermite Series Estimation in Nonlinear Cointegrating Models

This paper discusses nonparametric series estimation of integrable cointegration models using Hermite functions. We establish the uniform consistency and asymptotic normality of the series estimator. The Monte Carlo simulation results show that the performance of the estimator is numerically satisfactory. We then apply the estimator to estimate the stock return predictive function. The out-of-sample evaluation results suggest that dividend yield has nonlinear predictive power for stock returns while book-to-market ratio and earning-price ratio have little predictive power.
Mucinous neoplasms of the appendix: a current comprehensive clinicopathologic and imaging review

Abstract Mucinous neoplasms of the appendix are a heterogeneous group of neoplasms ranging from simple mucoceles to complex pseudomyxoma peritonei. Considerable controversy exists on their pathologic classification and nomenclature. Clear understanding of the histopathologic diversity of these neoplasms helps in establishing proper communication between the radiologist, the pathologist and the surgeon. In this article, we present a brief discussion of the current taxonomy and nomenclature of mucinous neoplasms of the appendix followed by a review of their imaging features. Important points including the significance of identifying extra-appendiceal mucin at imaging, the new classification of pseudomyxoma peritonei into low- and high-grade varieties and the significance of simultaneous ovarian and appendiceal neoplasms are highlighted.
Orthographic and Cognitive Factors in the Concurrent Development of Basic ReadingSkills in English and Persian

According to the “script dependent” hypothesis, accurate word recognition skills develop more slowly in languages with an irregular orthography, such as English, than in regular orthographies, such as Persian. According to the “central processing” hypothesis, basic reading skills in all languages are influenced primarily by underlying cognitive factors. These hypotheses were examined by studying the linguistic, cognitive, and basic reading skills of 70 children in Grades 1–5 learning to read concurrently in English (L1) and Persian (L2). Our findings supported both hypotheses. A consideration of these frameworks as complementary contributes to a crosslinguistic theory of reading skills development in bilingual children.
Exploring personal and organizational determinants of workplace bullying and its prevalence in a Japanese sample

Objective: The purpose of this study is twofold. First, we examine the prevalence rate of workplace bullying among employees in Japan. Second, we explore antecedents of bullying exposure at work in this population. Method: 699 employees recruited in 5 labor unions in the Tokyo area (Japan) voluntarily participated in this questionnaire-based study. We provided participants with a definition of bullying and asked them to indicate whether or not they have been bullied during the last six months according to this definition (self-labeling method). We also asked participants to complete items about a number of personal (e.g., gender, individual tendencies toward depression) and organizational (e.g., team cohesion, supervisor's support) variables. Results: The prevalence rate of workplace bullying was 15%. Regression analyses revealed that female workers reported higher levels of perceptions of being bullied than male workers. Additionally, depression was positively associated with perceptions of being bullied, whereas team cohesion, supervisor's support, and an innovation-oriented climate were negatively associated with being bullied. Conclusions: The present study demonstrates the importance of considering individual differences as predictors of bullying and, in particular, suggests that mental health promotion might play a role in bullying prevention. In addition, findings indicate that organizational interventions for workplace bullying may benefit from introducing elements aimed at improving group cohesion and organizational climate.
A Systematic Test of the Effective Schools Model

This article presents cross-sectional data on the relation between school achievement and measures of school environment, particularly “effective schools” characteristics. The data are for 38 high schools, 32 middle schools, and 134 elementary schools, across 22 districts in the Milwaukee metropolitan area. The achievement measures include standardized test data in math and reading, as well as dropout rates. In addition to a wide range of school characteristics, key measures of school environment were collected through lengthy mailed surveys of 5,500 teachers in the districts. In addition to an effective schools index, we analyze the effects of parental involvement and variation in teacher control of key decisions in schools. The findings offer support for the notion that school environment has an effect on achievement. They also show that the complex of environmental variables that are significantly related to achievement are themselves highly intercorrelated and very much affected by the location of the school (city or suburbs) and the student population in the schools. These results lead us to question the direction of causality and thus the certainty of success of intervention programs along current effective schools lines.
Chinese Lecturers' Perceptions, Problems and Strategies in Lecturing in English To Chinese- Speaking Students

This paper reports on the third stage of a longitudinal study into lecturing in English to non-English speaking students conducted at a university in Hong Kong. The first stage of this project (Flowerdew and Miller, 1992) focussed on the perceptions, problems and strategies of non-native speaking students receiving lectures in English from native-speaking lecturers. In the second stage of the project (Flowerdew and Miller, 1996a) the lecture situation was considered from the other side of the lecture equation, that of the lecturers. In the third stage of the project, which is reported here, the ESL lecture is again investigated from the lecturer's point of view, but this time the focus is not on expatriate native-speaking lecturers, but on local Chinese lecturers who share the L1 of their students and for whom English is also therefore a second language. After presenting the findings of this third stage of the project, the results of the three studies are compared and contrasted. Finally, the implications of the three studies when viewed collectively are considered and recommendations made for each of the three groups of subjects: NNS students, NS lecturers and NNS lecturers.
Extending the four-category model of adult attachment: An interpersonal model of friendship attachment

Relationships among adult friendship attachment styles and levels of hope, self-disclosure, relationship satisfaction, and trust were studied to assess their validity as explanatory factors in friendship attachments in a cross-section of 268 undergraduate students at a small, private university. Significant relationships were found between attachment styles and hope, self-disclosure, and relationship satisfaction. Specifically, securely attached individuals showed significantly more hope, self-disclosure, and relationship satisfaction than individuals with fearful attachment styles. In addition, individuals with fearful attachment styles showed significantly less hope, self-disclosure, and relationship satisfaction than individuals with secure, dismissing, or preoccupied attachment styles.
How intensive/prolonged should an intensive/prolonged treatment be?

Background : The issue of efficacy of aphasia therapy has long been debated and there is now convincing evidence that treatment is effective. More focused questions on aphasia therapy have also been addressed, although less frequently. This paper reviews the literature on the effect of intensity and duration of treatment. Aim s: Data in the literature on intensity and duration of treatment are reviewed. Main Contribution : Positive and negative studies on treated and untreated patients are reconsidered and the length of treatments in the two groups is compared. Studies directly tackling the question of intensity/duration of therapy are briefly reported as well as the results of a meta-analysis. Improvement in three pairs of matched subjects, all treated for very long periods of time but with different intensity, is compared. Conclusions : Results clearly indicate that the number of therapy sessions is an important factor in recovery. Results of the meta-analysis support this conclusion. There are also indications that when therapy is protracted for many months or even years with a very strict regimen (2–4 hours daily), aphasic subjects show clear improvement in their daily use of language and communicative competence.
Direct contact in inviting high-risk members of hereditary colon cancer families to genetic counselling and DNA testing

Background: Identification of hereditary predisposition to cancer has limited significance if not followed by efficient cancer prevention in the family. Probands are traditionally left to inform their relatives about the increased risk, but distant relatives may remain uninformed. An approach to contacting directly at-risk persons assumed to be unaware of their increased cancer risk was taken. With cancer prevention as the ultimate goal, the study was aimed at investigating attitudes towards and psychosocial consequences of this novel strategy. Methods: In families with hereditary non-polyposis colorectal cancer (Lynch syndrome), 286 healthy adult relatives with a 50% risk of a predisposing mutation were contacted by letter. Of these, 112 participated in counselling and predictive testing. Baseline information and information obtained 1 month after the test for 73 respondents were compared with 299 corresponding subjects, approached via the proband (family-mediated approach in our previous study) in these families. Results: After the contact letter, 51% consented to the study. Of these, 92% approved of the direct contact and 33% had tried to seek information. In 34% of the mutation carriers, neoplasia was identified in the first post-test colonoscopy. Although post-test fear of cancer increased among the mutation carriers and decreased among noncarriers, almost all participants were satisfied with their decision to participate, independently of their test results, parallel to the family-mediated approach. Conclusion: In this large-scale study, relatives in cancer families were actively contacted to inform them of the condition and genetic counselling. Their attitudes were encouraging, and the psychosocial consequences were similar to the family-mediated approach. Our results suggest the appropriateness of direct contact as an alternative method of contact in cases of life-threatening treatable disease.
Lymphotoxin αβ2 (Membrane Lymphotoxin) Is Critically Important for Resistance to Leishmania major Infection in Mice1

Although the essential role of TNF-α in the control of intracellular pathogens including Leishmania major is well established, it is uncertain whether the related cytokine lymphotoxin αβ2 (LTα1β2, membrane lymphotoxin) plays any role in this process. In this study, we investigated the contribution of membrane lymphotoxin in host response to L. major infection by using LTβ-deficient (LTβ−/−) mice on the resistant C57BL/6 background. Despite mounting early immune responses comparable to those of wild-type (WT) mice, LTβ−/− mice developed chronic nonhealing cutaneous lesions due to progressive and unresolving inflammation that is accompanied by uncontrolled parasite proliferation. This chronic disease was associated with striking reduction in IL-12 and Ag-specific IFN-γ production by splenocytes from infected mice. Consistent with defective cellular immune response, infected LTβ−/− mice had significantly low Ag-specific serum IgG1 and IgG2a levels compared with WT mice. Although administration of rIL-12 to L. major-infected LTβ−/− mice caused complete resolution of chronic lesions, it only partially (but significantly) reduced parasite proliferation. In contrast, blockade of LIGHT signaling in infected LTβ−/− mice resulted in acute and progressive lesion development, massive parasite proliferation, and dissemination to the visceral organs. Although infected LTβ−/− WT bone marrow chimeric mice were more resistant than LTβ−/− mice, they still had reduced ability to control parasites and showed defective IL-12 and IFN-γ production compared with infected WT mice. These results suggest that membrane lymphotoxin plays critical role in resistance to L. major by promoting effective T cell-mediated anti-Leishmania immunity.
Grid-Oriented Storage: A Single-Image, Cross-Domain, High-Bandwidth Architecture

This paper describes the grid-oriented storage (GOS) architecture and its implementations. A GOS-specific file system (GOS-FS), the single-purpose intent of a GOS OS, and secure interfaces via grid security infrastructure (GSI) motivate and enable this new architecture. As an FTP server, GOS with a slimmed OS, with a total volume of around 150 MB, outperforms the standard GridFTP by 20-40 percent. As a file server, GOS-FS acts as a network/grid interface, enabling a user to perform searches and access resources without downloading them locally. In the real-world tests between Cambridge and Beijing, where the transfer distance is 10,000 km, the multistreamed GOS-FS file opening/saving resulted in a remarkable performance increase of about 2-25 times, compared to the single-streamed network file system (NFSv4). GOS is expected to be a variant of or successor to the well-used network-attached storage (NAS) and/or storage area network (SAN) products in the grid era
The Fathers’ Dark Triumph: terror and the end of revolution in J.M. Coetzee’s The Master of Petersburg

This paper interrogates the work performed by the figure of the terrorist in J.M. Coetzee’s novel The Master of Petersburg (1994), a fictionalised account of the events prompting Fyodor Dostoevsky’s writing of the novel Demons. It does so to illustrate the waning of the cultural signs of revolt and revolution in the ways that they were valorised by the avant-garde movements of the twentieth century. The idea that writing is able to enact a revolt against the representational and epistemic violence of the symbolic order, is, I argue, one that Coetzee rejects. In denying writing revolutionary power, what emerges instead is the idea of art as itself terroristic: an act of violence rather than one of redemption.
The Impact of Cultural Background on Structural Figure Perception: Cultural Biases in the Reproduction of the Rey-Osterrieth Complex Figure

Visuo-spatial tests are often thought to be less subject to cultural bias than verbal tests. It has, however, been demonstrated that scores obtained, particularly using the Rey-Osterrieth Complex Figure, vary according to the cultural context. In a previous study, we noted that the socio-cultural environment had an impact on structural figure perception. We compared the techniques used to draw the figures by school-children in France from different cultural backgrounds, with the hypothesis that the culture handed down by the parents has an impact on structural figure perception (N = 914). Subjects were classified according to type of approach, based on the order in which tasks were performed using a computer recording of lines traced. Results demonstrate substantial contrasts among groups of children of different cultural origins. Inherited culture appears to influence structural figure perception, which could explain the variation in scores obtained. The impact of the familiarity with this type of task and educational level of the families are discussed.
