O poder social

o presente trabalho teve por objetivo investigar o relacionamento entre locus externo de causalidade e aquiescência de detentores de poder e a so1icitações de subordinados. Pesquisas anteriores realizadas nos Estado Unidos demonstraram das condições que afetam os indivíduos em situação de poder levando-os a atender as solicitações de dependentes. Esse estudo constitui uma réplica parcial do experimento de Schopler e Mathew B (1965) para o teste da mesma hipótese - o detentor de poder que percebe a dependência de seu parceiro motivada por fatores externos dar-lhe-á mais ajuda que quando percebe a dependência do parceiro motivada por auto escolha (fatores internos) - com sujeitos brasileiros. O mesmo “design” serviu para o teste de duas hipóteses adicionais: a) o detentor de poder ajuda mais sem parceiro dependente quando o custo da ajuda é baixo (hipótese de Thibaut e Kelly, 1967); b) o detentor de poder ajuda menos o parceiro, percebido como dependente por força de circunstâncias externas, quando conhece antecipadamente qual a sua solicitação (hipótese original deste trabalho). Os resultados confirmaram as hipóteses ao nível de 0,05. A discussão dos resultados obtidos foi desenvolvida em termos das teorias da troca e da reatância. Com base nos resu1tados conclui-se que: (1) as relações de poder não parecem ser influenciadas pela cultura em que os agentes estão inseridos; (2) a oposição à liberdade perdida pode explicar o menor atendimento a solicitações pré-conhecidas.

Atribuição de causalidade em presos, amputados e cegos: aceitação e luta contra o infortúnio

Os objetivos deste trabalho compreendem a determinação: (a) dos processos de atribuição de causalidade e responsabilidade empregados, por sujeitos presos, cegos e amputados, na explicação dos eventos que os vitimaram; (b) da relação entre os processos de atribuição de causalidade e as respostas de combate a situação; (c) da eficácia das teorias de busca de controle, mundo justo e atribuição defensiva na explicação dos eventos por parte dos sujeitos: (d) da influência do sentimento de auto-estima, crença no mundo justo, “locus" de controle e sentimento de religiosidade, na atribuição de causalidade; (e) de como os observadores emparelhados aos atores atribuição da causalidade e responsabilidade aos eventos vitimadores. A parte inicial consiste em uma revisão das principais contribuições teóricas ao fenômenos da atribuição de causalidade em psicologia social e das pesquisas a ele relacionadas; sua extensão se justifica pela inexistência de textos desta natureza em nossa língua. A segunda parte compreende a análise das respostas a conjunto de questionários e escalas fornecidas por 43 sujeitos presos por homicídio ou assalto, 40 amputados de membro superior ou inferior, 35 cegos congênitos ou adquiridos, e de 138 sujeitos observadores a eles emparelhados em idade, nível sócio-econômico e escolaridade. Os resultados indicam diferenças no processo de atribuição de causalidade empregado pelos sujeitos com perdas diversas e na utilização de princípios das três teorias consideradas. O mesmo se verifica quando se comparam sujeitos atores e observadores. Os dados mostram ainda relações entre as variáveis psicológicas e o processo de atribuição de causalidade, bem como a influência destas variáveis no processo de luta contra a perda sofrida.

Tomada de risco: um estudo sobre acidentes de trabalho

O desenvolvimento deste estudo objetivou examinar a relação existente entre propensão ao risco e acidentes do trabalho. Também foi examinado o papel representado pelas variáveis sexo e locus de controle, além de se proceder à construção de um instrumento para medir especificamente tomada de risco no ambiente de trabalho. O trabalho de campo utilizou um total de oitenta operários, semi-especializados (acidentados e não acidentados, de ambos os sexos), de forma a verificar as hipóteses de relação entre propensão de risco, locus de controle e sexo entre si e sua influência sobre a ocorrência ou não de acidentes de trabalho. O tratamento dos dados coletados revelou não haver ligação significativa entre as variáveis citadas e os acidentes de trabalho, bem como entre as variáveis entre si. Foram levantadas hipóteses a respeito de influências de características da amostra nos resultados. O instrumento construído mostrou-se útil para investigações desta natureza.

Atribuição de causalidade e de controle a loucura por diversos profissionais e por religiosos

O presente trabalho objetivou conhecer a percepção de profissionais de nível superior e religiosos sobre as causas e o controle da doença mental. Levantou-se opiniões de 360 profissionais (psicólogos, médicos e médicos psiquiatras, enfermeiros e enfermeiros psiquiatras, assistentes sociais, sociólogos, técnicos de administração, economistas e engenheiro s) e 60 religiosos (padres e freiras). Foram utilizadas duas escalas em forma de questionário: a Mental Health of Locus of Origin (MHLO) e a Mental Health Locus of Control (MHLC). Foi feita a distribuição dos sujeitos de acordo com os pontos obtidos em cada escala; discriminou-se o número de sujeitos que acreditam mais nas causas orgânicas da doença mental e o número de sujeitos que acreditam nas causas ambientais, segundo cada item da MHLO. Também discriminou-se quantos sujeitos acreditam que o sucesso da psicoterapia depende mais do comportamento do cliente e os que acreditam que tal sucesso depende mais da capacidade do terapeuta, segundo cada item da MHLC. Caluulou-se o coeficiente de correlação entre locus de origem e locus de controle da doença mental, e coeficiente de confiabilidade das duas escalas. As principais conclusões indicam que os psicólogos, assistentes sociais e ·sociólogos acreditam mais que os médicos e enfermeiros e estes mais do que os religiosos e os tecnólogos que a doença mental e causada por fatores ambientais e que o seu controle depende mais do comportamento do cliente do que d a capacidade do terapeuta.

Fatores que influenciam a qualidade de vida de pessoas com epilepsia

Epilepsy is a chronic disorder that impairs life quality (LQ) and interferes in emotional, personal, social and family relationship aspects. This study evaluated 165 people with epilepsy diagnosis, ranging from 18 to 75 years old (M=41,28; SD= 13,26), by means of the QQV-65 (Life Quality Questionnaire with 65 questions) and investigated the association between the questionnaire scores and the disease features, comparing patients who showed refrectory seizures with patients with partially controled seizures. There was no difference in relation to the two groups regarding the LQ factor. The QQV-65 emotional factor was the most affected in both groups, since the estimated mean z-escore was 51,0±14,4 for Group I and 49,9±14,7 for Group II. Regarding the type of crisis, the analysis of variance (ANOVA) revealed that Health was the only factor in QQV-65 that showed a statistically significant difference between the z-scores (P = 0.024). However, for the frequency of epileptic seizures, except Health (P = 0.185), other factors QQV-65 proved to be related in a statistically significant way (P> 0.05). The research demonstrated that seizure control perception is quite important in the evaluation of life quality in all its aspects (health, body, society, emotion, locus of control, self-concept and cognition).

Semantic coordination through programmable Tuple spaces

Two of the main features of today complex software systems like pervasive computing systems and Internet-based applications are distribution and openness. Distribution revolves around three orthogonal dimensions: (i) distribution of control|systems are characterised by several independent computational entities and devices, each representing an autonomous and proactive locus of control; (ii) spatial distribution|entities and devices are physically distributed and connected in a global (such as the Internet) or local network; and (iii) temporal distribution|interacting system components come and go over time, and are not required to be available for interaction at the same time. Openness deals with the heterogeneity and dynamism of system components: complex computational systems are open to the integration of diverse components, heterogeneous in terms of architecture and technology, and are dynamic since they allow components to be updated, added, or removed while the system is running. The engineering of open and distributed computational systems mandates for the adoption of a software infrastructure whose underlying model and technology could provide the required level of uncoupling among system components. This is the main motivation behind current research trends in the area of coordination middleware to exploit tuple-based coordination models in the engineering of complex software systems, since they intrinsically provide coordinated components with communication uncoupling and further details in the references therein. An additional daunting challenge for tuple-based models comes from knowledge-intensive application scenarios, namely, scenarios where most of the activities are based on knowledge in some form|and where knowledge becomes the prominent means by which systems get coordinated. Handling knowledge in tuple-based systems induces problems in terms of syntax - e.g., two tuples containing the same data may not match due to differences in the tuple structure - and (mostly) of semantics|e.g., two tuples representing the same information may not match based on a dierent syntax adopted. Till now, the problem has been faced by exploiting tuple-based coordination within a middleware for knowledge intensive environments: e.g., experiments with tuple-based coordination within a Semantic Web middleware (surveys analogous approaches). However, they appear to be designed to tackle the design of coordination for specic application contexts like Semantic Web and Semantic Web Services, and they result in a rather involved extension of the tuple space model. The main goal of this thesis was to conceive a more general approach to semantic coordination. In particular, it was developed the model and technology of semantic tuple centres. It is adopted the tuple centre model as main coordination abstraction to manage system interactions. A tuple centre can be seen as a programmable tuple space, i.e. an extension of a Linda tuple space, where the behaviour of the tuple space can be programmed so as to react to interaction events. By encapsulating coordination laws within coordination media, tuple centres promote coordination uncoupling among coordinated components. Then, the tuple centre model was semantically enriched: a main design choice in this work was to try not to completely redesign the existing syntactic tuple space model, but rather provide a smooth extension that { although supporting semantic reasoning { keep the simplicity of tuple and tuple matching as easier as possible. By encapsulating the semantic representation of the domain of discourse within coordination media, semantic tuple centres promote semantic uncoupling among coordinated components. The main contributions of the thesis are: (i) the design of the semantic tuple centre model; (ii) the implementation and evaluation of the model based on an existent coordination infrastructure; (iii) a view of the application scenarios in which semantic tuple centres seem to be suitable as coordination media.

Betreuungsbedürfnisse von Patientinnen im Rahmen der gynäkologischen Krebsfrüherkennungsuntersuchung : Entwicklung eines Erfassungsinstrumentes

Da es bis dato kein spezifisches Instrument gibt, um die Betreuungsbedürfnisse von Patientinnen im Rahmen der gynäkologischen Krebsfrüherkennungsuntersuchung zu erfassen, war es das Ziel der vorliegenden explorativen Studie, eben jene subjektiven Betreuungsbedürfnisse aufzudecken und sie in ein praxistaugliches und messbares Format zu überführen - den Fragebogen „Betreuungsbedürfnisse – Gynäkologische Krebsfrüherkennungsuntersuchung (BB-G KFU)“. Wir stellten hierzu folgende Hypothesen auf: Es ist möglich (a) Betreuungsbedürfnisse zu explorieren und in reliablen Skalen abzubilden, (b) die Wichtigkeit der Betreuungsbedürfnisse in Form einer Wertigkeitsrangfolge abzubilden, (c) Determinanten der Betreuungsbedürfnisse (Alter, Sozialstatus, Familienstand, Gesundheitsbezogene Kontrollüberzeugungen) zu detektieren. Wir entwickelten einen Fragebogen auf der Basis einer ausführlichen systematischen Literaturrecherche, Leitfadeninterviews mit gynäkologischen Patientinnen sowie einer Befragung von 18 Experten. Dieser Fragebogen beinhaltete 58 Arzt bezogene Betreuungsbedürfnisse-Items, 12 Arzthelferinnen bezogene Betreuungsbedürfnisse-Items und 21 Praxisorganisation und Praxisstruktur bezogene Betreuungsbedürfnisse-Items. Die Probandinnen bewerteten die Wichtigkeit der Erfüllung jedes Items anhand einer fünfstufigen Antwortskala im Likert-Format (1 = nicht wichtig, 5 = sehr wichtig). Zudem wurden soziodemografische Daten sowie gesundheitsbezogene Kontrollüberzeugungen der Probandinnen erhoben. Im Sinne einer multizentrisch angelegten Querschnittstudie wurde der Fragebogen an 1.000 Patientinnen in zehn gynäkologischen Praxen in drei deutschen Bundesländern ausgegeben. Insgesamt erhielten wir 965 ausgefüllte Fragebögen zurück. Mittels deskriptiver Statistiken konnten die soziodemografischen Daten sowie die einzelnen Betreuungsbedürfnisse-Items ausgewertet werden. Zur Entwicklung reliabler Betreuungsbedürfnis-Skalen wurde der Datensatz einer Hauptkomponentenanalyse (PCA mit Varimax-Rotation) unterzogen. Auf diesem Wege konnte ein Erfassungsinstrument (Fragebogen „Betreuungsbedürfnisse – Gynäkologische Krebsfrüherkennungsuntersuchung (BB-G KFU)“) bestehend aus sieben reliablen Betreuungsbedürfnis-Skalen (BB-S) entwickelt werden, welche die psychosozialen Betreuungsbedürfnisse und -wünsche von Patientinnen mit Bezug auf den Gynäkologen (BB-S-A), die Arzthelferin (BB-S-AH) sowie die Praxisstruktur (BB-S-P) abzubilden vermögen: „Bedürfnis nach Information“ (BB-S-A-I), „Bedürfnis nach Respekt und Einfühlungsvermögen im Rahmen der körperlichen Untersuchung“ (BB-S-A-RE), „Bedürfnis nach Zuwendung und Verfügbarkeit“ (BB-S-A-ZV), „Bedürfnis nach Zuwendung und Service“ (BB-S-AH-ZS), „Bedürfnis nach logistischer Unterstützung“ (BB-S-AH-L), „Bedürfnis nach Basisausstattung und Erreichbarkeit“ (BB-S-P-BE) und „Bedürfnis nach Zusatzausstattung“ (BB-S-P-Z). Die durch die drei arztbezogenen Komponenten (bestehend aus 33 Items) aufgeklärte Gesamtvarianz beträgt 40,29%, die der arzthelferinnenbezogenen 2-Komponentenlösung (11 Items) 48,92%, und die Totalvarianz der zwei Dimensionen mit Bezug auf die Praxisstruktur (19 Items) liegt bei 41,68%. Die Reliabilitäten der sieben Skalen sind als akzeptabel bis sehr gut zu bewerten (Cronbachs α = .71 - .89). Anhand der Korrelationen zum KKG (Fragen zu Kontrollüberzeugungen über Krankheit und Gesundheit von Lohaus und Schmitt) konnten erste positive Hinweise auf die Validität des BB-G KFU gefunden werden. Durch den Vergleich der einzelnen Mittelwerte konnte die hierarchische Organisation der Betreuungsbedürfnisse gemäß ihrer Wichtigkeit sichtbar gemacht werden: Die Arbeit zeigt, dass Patientinnen im Rahmen der gynäkologischen KFU der Informationsvermittlung durch den Arzt (BB-S-A-I; M = 1,51; SD = 0,47) wie auch der ärztlichen Zuwendung und Verfügbarkeit (BB-S-A-ZV; M = 1,39; SD = 0,38) in der Wertigkeitsrangfolge einen besonders hohen Platz einräumen. Die Datenanalysen zeigen zudem eine Abhängigkeit der Betreuungsbedürfnisse vom Alter und vom Sozialstatus der Patientinnen, jedoch nicht vom Familienstand und den gesundheitsbezogenen Kontrollüberzeugungen.

Trust and Social Networks in a Changing Europe.

This project set out to investigate the effects of the recent massive social transitions in Eastern Europe on the everyday social lives of the inhabitants of three very different nations: Georgia, Russia and Hungary. It focused in particular on the availability and nature of the support networks available to three different segments of each of the societies (manual workers, students and entrepreneurs) and the impact of network participation on psychological and physical well-being. The group set four specific questions to investigate: the part played by individual psychological beliefs in the formation and maintenance of social networks and the consequent formation of trusting relations; the implication of the size and quality of these networks for mental health; the nature of the social groups inhabited by the respondents and the implication of their work schedule and daily routines on the maintenance of a social and family life; and an analysis of how cultures vary in their social networks and intimacy. Three different methods were used to examine social support and its implications: structured questionnaires, semi-structured short interviews and a media analysis of newspaper materials. The questionnaires were administered to 150 participants in each country, equally divided between students studying full time, manual workers employed in factories, and business people (small kiosk owners, whose work and life style differs considerably from that of the manual workers). The questionnaires investigated various predictors of social support including the locus of control, relationship beliefs, individualism-collectivism and egalitarianism, demographic variables (age, gender and occupation), social support, both in general and in relation to significant events that have occurred since the transition from communism. Those with an internal locus of control were more likely to report a higher level of social support, as were collectivists, while age too was a significant predictor, with younger respondents enjoying higher levels of support, regardless of the measures of support employed. Respondents across the cultures referred to a decline of social support and the group also found a direct correlation between social support and mental health outcomes. All 450 respondents were interviewed on their general responses to changes in their lives since the fall of communism and the effects of their work lives on their social lives and the home environment. The interviews revealed considerable variations in the way in which work-life offered opportunities for a broader social life and also provided a hindrance to the development of fulfilling relationships. Many of the work experiences discussed were culture specific, with work having a particularly negative impact on the social life of Russian entrepreneurs but being seen much more positively in Georgia. This may reflect the nature of support offered in a society as overall support levels were lowest in Russia, meaning that social support may be of particular importance there. The way in cultural values and norms about personal relationships are transmitted in a culture is a critical issue for social psychologists and the group examined newspaper articles in those newspapers read by the respondents in each of the three countries. These revealed a number of different themes. The concept of a divided society and its implications for personal relationships was clearest in Russian and Hungary, where widely-read newspapers dwelt on the contrast between "new Russians/Hungarians" and the older, poorer ones and extended considerable sympathy to those suffering from neglect in institutions. Magyar Nemzet, a paper widely read by Hungarian students reflects the generally more pessimistic tone about personal relationships in Russia and Hungary and gave a particularly detailed analysis of the implications this holds for human relations in a modern society. In Georgia, however, the tone of the newspapers is more positive, stressing greater social cohesion. Part of this cohesion is framed in the context of religion, with the church appealing to a broader egalitarianism, whereas in less egalitarian Hungary appeals by the Church are centred more on the nuclear family and its need for expansion in both size and influence. The division between the sexes was another prominent issue in Hungary and Russia, while the theme of generational conflict also emerged in Hungarian and Georgian papers, although with some understanding of "young people today". The team's original expectation that the different newspapers read by the different groups of respondents would present differing images of personal relationships was not fulfilled, as despite variations in style, they found little clear "ideological targeting" of any particular readership. They conclude that the vast majority of respondents recognised that the social transition from communism has had a significant impact on the well-being of social relationships and that this is a pertinent issue for all segments of society. While the group see the data collected as a source to be worked on for some time in the future, their initial impressions include the following. Social support is clearly an important concern across all three countries. All respondents (including the students) lament the time taken up by their heavy work schedules and value their social networks and family ties in particular. The level of social support differs across the countries investigated, with Georgian apparently enjoying significantly higher levels of social support. The analysis produced an image of a relatively cohesive and egalitarian society in which even the group most often seen as distant from the general population, business people, is supported by a strong social network. In contrast, the support networks available to the Russian respondents seem particularly weak and reflect a general sense of division and alienation within the culture as a whole. The implications of low levels of social support may vary across countries. While Russians reported the lowest level of mental health problems, the link between social support and mental health may be strongest in that country. In contrast, in Hungary it is the link between fatalism and mental health problems which is particularly strong, while in Georgia the strongest correlation was between mental health and marital quality, emphasising the significance of the marital relationship in that country.

Assessing Difficulties in Career Decision Making Among Swiss Adolescents with the German My Vocational Situation Scale

Assessing problems in career decision making among adolescents is important for career guidance and research. The present study is the first to investigate among Swiss adolescents the factor structure and convergent validity in relation to personality of the German-language adaptation of the My Vocational Situation Scale. Two preliminary studies (N = 217) suggested that using a 5-point Likert scale response format would increase scale reliability. The confirmatory factor analyses in the main study with two cohorts (n = 341, eighth grade; n = 303, eleventh grade) confirmed that four main factors, which assess problems with identity, decision making, information, and perceived barriers, underlie the data. The barriers factor was differentiated into aspired vocation and personal situation. Construct validity was supported by significant relationships between favorable personality characteristics (emotional stability, extraversion, agreeableness, conscientiousness, generalized self-efficacy, and internal locus of control) and fewer problems. The results suggest that the vocational identity and barriers scales can be fruitfully applied to research on and the practice of career counseling with adolescents.

Dyslexia: Success, Failure, and Self-Concept

The purpose of this study is to investigate the experience of college-aged students who have been diagnosed with dyslexia. Research has shown that many people with dyslexia experience a variety of social and emotional struggles throughout their education. Using qualitative research techniques, this study provides a description of the experience common among college students with dyslexia. Specifically, the study examines the experience of dyslexic students as it relates to attributions of successes and failures, locus of control, self-concept, and how personal knowledge about the diagnosis impacts their experience.

Factors affecting student attitudes toward flexible online learning in management education

In response to recent technological advances and the trend toward flexible learning in education, the authors examined the factors affecting student satisfaction with flexible online learning. The authors identified 2 key student attributes of student satisfaction: (a) positive perceptions of technology in terms of ease of access and use of online flexible learning material and (b) autonomous and innovative learning styles. The authors derived measures of perceptions of technology from research on the Technology Acceptance Model and used locus of control and innovative attitude as indicators of an autonomous and innovative learning mode. First-year students undertaking an introductory management course completed surveys at the beginning (n = 248) and at the end (n = 256) of course work. The authors analyzed the data by using structural equation modeling. Results suggest that student satisfaction is influenced by positive perceptions toward technology and an autonomous learning mode.

Psychosocial barriers to self -care among Hispanic women with type 2 diabetes mellitus

This cross-sectional survey-designed study investigated the presence and influence of psychosocial barriers to diabetes self-management practices among Hispanic women with type 2 diabetes mellitus. Women (n = 128) who were diagnosed and being treated for type 2 diabetes were recruited from the Miami-Dade area in South Florida. A Beck Depression Inventory-II, Diabetes Care Profile, Diabetes Knowledge Test, Diabetes Empowerment, Multidimensional Health Locus of Control, and Perceived Stress Scales were administered, along with assessment of diet through a 24-hour recall and anthropometric evaluation by body composition analysis and body mass index computation. ^ Mean (± SD) age for subjects was 50.15 ± 15.93 and age at diagnosis was 42.46 ± 14.69. Mean glycosylated hemoglobin (A 1C) was 8.55 ± 1.39. Diabetes education had not been received by 46.9% of subjects. Psychosocial status had previously been evaluated in only 4 participants. Forty percent of participants were assessed as depressed and 17% moderately to severely so. Depression correlated significantly (p < 0.01) with A1C (r = 0.242), perceived stress (r = 0.566), and self-rated health (r = −0.523). Perceived stress correlated significantly (p < 0.01) with A1C (r = 0.388), understanding of diabetes (r = 0.282), self-rated health (r = −0.372) and diabetes empowerment (r = −0.366). For Cuban women, perceived stress (β = 0.418, p = 0.033) was the only significant predictor of A1C, while among non-Cuban Hispanic women, self-reported health (β = −0.418, p = 0.003) and empowerment (β = 0.432, p = 0.004) were better predictors. The most desirable DM status among the women surveyed (high diet adherence, low exercise barriers, and A1C ≤ 7) was associated with superior self-rated health, more support from family and friends, and greater empowerment. ^ This study revealed the error in considering Hispanics a homogenous entity in treating disease, as their cultural backgrounds and concentration in a community can greatly influence management of a chronic disease like diabetes. The strong correlations found between diabetes-related health indicators and psychosocial factors such as depression and perceived stress suggest that psychosocial assessment of patients must be more strongly advocated in diabetes care. Psychosocial assessment of ethnically diverse diabetic populations is especially vital if greater knowledge is to be gained about their barriers to self-care so that diabetes treatment and thus outcomes are enhanced. ^

Redefinición de las TIC en el museo: del discurso invasivo al inclusivo

Las TIC son inseparables de la museografía in situ e imprescindibles en la museografía en red fija y móvil. En demasiados casos se han instalado prótesis tecnológicas para barnizar de modernidad el espacio cultural, olvidando que la tecnología debe estar al servicio de los contenidos de manera que resulte invisible y perfectamente imbricada con la museografía tradicional. Las interfaces móviles pueden fusionar museo in situ y en red y acompañar a las personas más allá del espacio físico. Esa fusión debe partir de una base de datos narrativa y abierta a obras materiales e inmateriales de otros museos de manera que no se trasladen las limitaciones del museo físico al virtual. En el museo in situ tienen sentido las instalaciones hipermedia inmersivas que faciliten experiencias culturales innovadoras. La interactividad (relaciones virtuales) debe convivir con la interacción (relaciones físicas y personales) y estar al servicio de todas las personas, partiendo de que todas, todos tenemos limitaciones. Trabajar interdisciplinarmente ayuda a comprender mejor el museo para ponerlo al servicio de las personas.
