Alcoholic women and men: a comparative study of social and familial aspects and outcome

Objetivos: A proporção de ocorrência de alcoolismo em homens e mulheres tem uma variação de 14:1 até 2:1, mostrando a necessidade de estudos específicos para a população feminina. O objetivo deste estudo foi analisar o perfil e a evolução de alcoolistas, segundo gênero e gravidade da dependência. Métodos: Realizou-se um estudo longitudinal retrospectivo de 114 homens e 57 mulheres alcoolistas (CID-10), inscritos no ambulatório da Faculdade de Medicina de Botucatu, no período de 1990-1994 e avaliados até julho de 1997. Utilizou-se um questionário semi-estruturado, e, para avaliação da gravidade do alcoolismo, o Short Alcohol Dependence Data. Resultados/Conclusões: Os principais resultados mostraram que a estrutura familiar estava comprometida com: relacionamento difícil para 55,6% das mulheres e 65,7% dos homens; violência familiar em 74,1% das mulheres e 61,1% dos homens. As mulheres iniciaram a ingestão mais tarde que os homens (p=0,01), em geral com seus cônjuges (p=0,00). Não houve diferença de evolução no tratamento entre os gêneros. Os principais fatores associados à melhor resposta ao tratamento, independentemente do sexo, foram: nível de gravidade de dependência do álcool (dependentes leves e moderados apresentaram 5,59 vezes mais chances de melhorar do que os dependentes graves); ser praticante de alguma religião (2,3 vezes mais chances de melhora do que os pacientes que não eram praticantes); e tempo de seguimento no programa, negativamente correlacionado a chances de melhora (0,68 vezes menos chances de melhora que aqueles que permaneceram por tempo menor em tratamento).

Social and financial aspects of the artisanal fisheries of Middle Sao Francisco River, Minas Gerais, Brazil

The presence or absence of motorized boats, partnerships and multispecies catches characterize the fisheries of Sao Francisco River, Minas Gerais, Brazil. Fishing activity based on 109 interviews, carried out in the wet (high water: February and March) and dry (low water: July and August) seasons, with professional fishermen are described. Aiming to identify the fishery income components, a covariance model was proposed, with the income as the response variable, related to the factors: fishing ground, use of motorized or paddle boat; seasonality; presence of fishing assistant, and the following covariates: capture in weight in the week Frier to the interview, fisherman experience in yrs; and distance (km) travelled for fishing. The results indicated that the main contributions to income were the absence of an engine (because of high price of the fuel), the absence of a partner (because of low capture) and the amount of fish caught by the fishermen.

Nutritional and social hierarchy establishment of the primitively eusocial wasp Mischocyttarus cassununga (Hymenoptera, Vespidae, Mischocyttarini) and related aspects

The results on the nutritional influence in the social hierarchy establishment among females from six colonies of Mischocyttarus cassununga show that: - there was no caste determination in the pre-imaginal period concerning ingested food quantities, however, in relation to qualification (proteins and carbohydrate) the Mann-Whitney test applied showed variation among colonies: in two colonics (colony 3, p=0.0209; colony 4, p=0.0090) the larvae which ingested a higher quantity of solid food became adults of hierarchically higher position, however in two other colonies, colony 1 (p=0.6744) and colony 2 (p=0.3367) this difference was not statistically significant; in two experimentally manipulated colonies the caste determination was observed in the imaginal phase (it was verified that the larger the food quantity consumed, the higher the assumed hierarchical position by the individuals); - adult individuals of hierarchically higher position in two colonies ingested a greater amount of solid than liquid food (Mann-Whitney; p ≤ 0.05), however in the other three colonies there was no difference. It can be seen that for all colonies (2, 3, 4, 5 and 6) the high tendency to solid food ingestion occurs. In colony 1, this data was not collected because the observation purpose was different); - inside the colony hierarchy, the older individuals were the ones that occupied higher hierarchical positions; - more than one inseminated female per colony was found in the two experimentally manipulated colonies ; - ovarian development is greater in inseminated females; - the average height of the 3rd tergite was greater for inseminated females, indicating an adaptation to accommodate larger ovary development (t-Student test; p ≤ 0.05).

Long-term follow-up in patients with Lennox-Gastaut syndrome. Epileptological aspects, psychomotor development and social adaptation

In 1989/90 a follow-up was made possible on 72 of 78 patients who have been treated for the supposed or confirmed diagnosis of a Lennox-Gastaut-Syndrome at the university children hospital of Berne between 1964 and 1978. Nine patients were excluded of this study because the diagnosis was proved wrong retrospectively, leaving 63 cases. Of these, eleven patients (17.5%) have died. The remaining 52 (82.5%) were evaluated regarding their epilepsy, psychomotor development and social adaptation. The follow-up was good for 14.3%, intermediate for 23.8% and poor for 44.4%. Bad prognostic factors were found to be: first manifestation of epilepsy during the first year of life, occurrence of infantile spasms or hypsarrhythmia in the EEG and pathological neurological signs at the beginning of the disease. In the course of illness a change of seizure phenomenology was observed. The infantile spasms were seen only during the first three years of epilepsy. After the second year of disease psychomotor seizures became more and more frequent. Atypical absences, already seen at the beginning, were the most frequent form of seizure from the third year of epilepsy until the end of our observations. During the course of disease the frequency of generalized tonic and tonic-clonic seizures decreased little.

Interrelationships between the structural and functional aspects of social relationships, comorbidity and health related quality of life in breast cancer survivors

It is widely acknowledged in theoretical and empirical literature that social relationships, comprising of structural measures (social networks) and functional measures (perceived social support) have an undeniable effect on health outcomes. However, the actual mechanism of this effect has yet to be clearly understood or explicated. In addition, comorbidity is found to adversely affect social relationships and health related quality of life (a valued outcome measure in cancer patients and survivors). ^ This cross sectional study uses selected baseline data (N=3088) from the Women's Healthy Eating and Living (WHEL) study. Lisrel 8.72 was used for the latent variable structural equation modeling. Due to the ordinal nature of the data, Weighted Least Squares (WLS) method of estimation using Asymptotic Distribution Free covariance matrices was chosen for this analysis. The primary exogenous predictor variables are Social Networks and Comorbidity; Perceived Social Support is the endogenous predictor variable. Three dimensions of HRQoL, physical, mental and satisfaction with current quality of life were the outcome variables. ^ This study hypothesizes and tests the mechanism and pathways between comorbidity, social relationships and HRQoL using latent variable structural equation modeling. After testing the measurement models of social networks and perceived social support, a structural model hypothesizing associations between the latent exogenous and endogenous variables was tested. The results of the study after listwise deletion (N=2131) mostly confirmed the hypothesized relationships (TLI, CFI >0.95, RMSEA = 0.05, p=0.15). Comorbidity was adversely associated with all three HRQoL outcomes. Strong ties were negatively associated with perceived social support; social network had a strong positive association with perceived social support, which served as a mediator between social networks and HRQoL. Mental health quality of life was the most adversely affected by the predictor variables. ^ This study is a preliminary look at the integration of structural and functional measures of social relationships, comorbidity and three HRQoL indicators using LVSEM. Developing stronger social networks and forming supportive relationships is beneficial for health outcomes such as HRQoL of cancer survivors. Thus, the medical community treating cancer survivors as well as the survivor's social networks need to be informed and cognizant of these possible relationships. ^

Blogs: On the Cutting Edge of the Next-generation Web

This article analyses a number of social and cultural aspects of the blog phenomenon with the methodological aid of a complexity model, the New Techno-social Environment (hereinafter also referred to by its Spanish acronym, NET, or Nuevo Entorno Tecnosocial) together with the socio-technical approach of the two blogologist authors. Both authors are researchers interested in the new reality of the Digital Universal Network (DUN). After a review of some basic definitions, the article moves on to highlight some key characteristics of an emerging blog culture and relates them to the properties of the NET. Then, after a brief practical parenthesis for people entering the blogosphere for the first time, we present some reflections on blogs as an evolution of virtual communities and on the changes experienced by the inhabitants of the infocity emerging from within the NET. The article concludes with a somewhat disturbing question; whether among these changes there might not be a gradual transformation of the structure and form of human intelligence.

Asimismo se expone un análisis teórico-práctico del cálculo del retorno de la inversión (ROI) y por último un análisis de la información recopilada en las encuestas y en el estudio estadístico de la red social corporativa. Los datos de las encuestas fueron analizados mediante estadística descriptiva basada en gráficos y tablas de contingencia donde se calculan residuos y porcentajes totales para analizar la dependencia entre el social media, eficiencia, productividad y cuenta de resultados, además del análisis de la aportación del social media a la misión, comunicación interna y gestión del conocimiento en la empresa. También se realizan cálculos de distribuciones Chi-cuadrado para demostrar la dependencia del social media-productividad y del GAP que relaciona la importancia y el nivel de satisfacción del social media. En el análisis teórico-práctico se toman como parámetros los beneficios, costes, flexibilidad y riesgo. Los beneficios van ligados a la productividad, gestión del conocimiento, capital humano y procesos internos. Los costes a las licencias de software, administración, implementación y formación. A partir de estos parámetros se realizó el estudio de un modelo de empresa que representa a una gran empresa de las TIC en España. Los datos para el estudio son estimativos dentro de la realidad, debido a que la intención no es saber estos valores reales sino el estudio teórico-práctico del método y su aplicación para el calculo del ROI. El estudio estadístico del la red social se realizo durante tres meses y se obtuvo el progreso de uso de la red social en eventos tales como: número de participantes activos, mensajes publicados, archivos subidos, grupos activos y tipos y plataformas de acceso. Del estudio de los datos estadísticos de estos eventos se obtuvieron indicadores de participación, actividad y conocimiento de la red social que son útiles par el calculo del ROI. En conclusión, se demuestran las mejoras que ofrece el social media en campos como la comunicación interna, gestión del conocimiento, formación e innovación. Y gracias a estas mejoras el aumento de la productividad y eficiencia del profesional y asimismo un potencial retorno de la inversión (ROI). ABSTRACT. This paper deals with the study of the implementation and development of the different platforms of social media: social networks and knowledge, blogs and collaborative tools in the corporate enterprise level. The study collects information technology consulting, articles and several social media platforms and an investigation into the question raised is performed. Analysis of 42 surveys of professionals from two big companies telecommunications in Spain are included. These two companies have one about 28000 employees and another with more than 300 employees at its Spanish subsidiaries. Both have a strong international presence. These two companies differ from other companies in the telecommunications sector they are betting in the implementation of social media in their internal processes. Furthermore, the study and analysis of usage statistics and a series of surveys on the wall of the corporate social network of a multinational telecommunications is included for three months. A new social culture enterprise is presented innovative in areas such as knowledge management, internal communications, training and innovation. And a quantitative vision into implementation of social media in the processes of a company is offered. They develops an exhibition where shown the process of studying the different social media platforms and application areas in the company, the study of the legal aspects of your application and use and implementation and development. A theoretical and practical analysis also exposed of calculation of return on investment (ROI) and finally an analysis of the information collected in surveys and statistical study of corporate social network. The survey data were analyzed using descriptive statistics based on graphs and contingency tables where waste and total percentages are calculated for analyze the dependence between the social media, efficiency, productivity and income statement, plus analysis of the contribution of social media on the mission, internal communication and knowledge management in the company. Also Calculations of chi-square distributions are conducted to demonstrate the dependence between of productivity and social media and the GAP that relates the importance and satisfaction level in social media. The theoretical and practical analysis parameters are the benefits, costs, flexibility and risk. The benefits are linked to productivity, knowledge management, human capital and internal processes. The costs are linked the software licensing, management, implementation and training. Based on these parameters was performed the study of a business model that represents a large ICT company in Spain. The data for the study are estimates within the reality, because the intention is not to know these real values but the theoretical and practical study and application of the method for calculating the ROI. Statistical analysis of the social network was made during or three months and was obtained the progress of social network use at events such as: number of active participants, messages posted, files uploaded, active groups and types and access platforms. Into study of statistical data of these events were obtained indicators of participation, activity and knowledge of the social network that are useful for calculating the ROI. In conclusion, the improvements offered by the social media in areas such as internal communication, knowledge management, training and innovation are shown. And thanks to these improvements increase the productivity and efficiency of professional and also a potential return on investment (ROI).

Análisis de los factores de influencia en la adopción de herramientas colaborativas basadas en software social. Aplicación a entornos empresariales

En las últimas dos décadas, se ha puesto de relieve la importancia de los procesos de adquisición y difusión del conocimiento dentro de las empresas, y por consiguiente el estudio de estos procesos y la implementación de tecnologías que los faciliten ha sido un tema que ha despertado un creciente interés en la comunidad científica. Con el fin de facilitar y optimizar la adquisición y la difusión del conocimiento, las organizaciones jerárquicas han evolucionado hacia una configuración más plana, con estructuras en red que resulten más ágiles, disminuyendo la dependencia de una autoridad centralizada, y constituyendo organizaciones orientadas a trabajar en equipo. Al mismo tiempo, se ha producido un rápido desarrollo de las herramientas de colaboración Web 2.0, tales como blogs y wikis. Estas herramientas de colaboración se caracterizan por una importante componente social, y pueden alcanzar todo su potencial cuando se despliegan en las estructuras organizacionales planas. La Web 2.0 aparece como un concepto enfrentado al conjunto de tecnologías que existían a finales de los 90s basadas en sitios web, y se basa en la participación de los propios usuarios. Empresas del Fortune 500 –HP, IBM, Xerox, Cisco– las adoptan de inmediato, aunque no hay unanimidad sobre su utilidad real ni sobre cómo medirla. Esto se debe en parte a que no se entienden bien los factores que llevan a los empleados a adoptarlas, lo que ha llevado a fracasos en la implantación debido a la existencia de algunas barreras. Dada esta situación, y ante las ventajas teóricas que tienen estas herramientas de colaboración Web 2.0 para las empresas, los directivos de éstas y la comunidad científica muestran un interés creciente en conocer la respuesta a la pregunta: ¿cuáles son los factores que contribuyen a que los empleados de las empresas adopten estas herramientas Web 2.0 para colaborar? La respuesta a esta pregunta es compleja ya que se trata de herramientas relativamente nuevas en el contexto empresarial mediante las cuales se puede llevar a cabo la gestión del conocimiento en lugar del manejo de la información. El planteamiento que se ha llevado a cabo en este trabajo para dar respuesta a esta pregunta es la aplicación de los modelos de adopción tecnológica, que se basan en las percepciones de los individuos sobre diferentes aspectos relacionados con el uso de la tecnología. Bajo este enfoque, este trabajo tiene como objetivo principal el estudio de los factores que influyen en la adopción de blogs y wikis en empresas, mediante un modelo predictivo, teórico y unificado, de adopción tecnológica, con un planteamiento holístico a partir de la literatura de los modelos de adopción tecnológica y de las particularidades que presentan las herramientas bajo estudio y en el contexto especifico. Este modelo teórico permitirá determinar aquellos factores que predicen la intención de uso de las herramientas y el uso real de las mismas. El trabajo de investigación científica se estructura en cinco partes: introducción al tema de investigación, desarrollo del marco teórico, diseño del trabajo de investigación, análisis empírico, y elaboración de conclusiones. Desde el punto de vista de la estructura de la memoria de la tesis, las cinco partes mencionadas se desarrollan de forma secuencial a lo largo de siete capítulos, correspondiendo la primera parte al capítulo 1, la segunda a los capítulos 2 y 3, la tercera parte a los capítulos 4 y 5, la cuarta parte al capítulo 6, y la quinta y última parte al capítulo 7. El contenido del capítulo 1 se centra en el planteamiento del problema de investigación así como en los objetivos, principal y secundarios, que se pretenden cumplir a lo largo del trabajo. Así mismo, se expondrá el concepto de colaboración y su encaje con las herramientas colaborativas Web 2.0 que se plantean en la investigación y una introducción a los modelos de adopción tecnológica. A continuación se expone la justificación de la investigación, los objetivos de la misma y el plan de trabajo para su elaboración. Una vez introducido el tema de investigación, en el capítulo 2 se lleva a cabo una revisión de la evolución de los principales modelos de adopción tecnológica existentes (IDT, TRA, SCT, TPB, DTPB, C-TAM-TPB, UTAUT, UTAUT2), dando cuenta de sus fundamentos y factores empleados. Sobre la base de los modelos de adopción tecnológica expuestos en el capítulo 2, en el capítulo 3 se estudian los factores que se han expuesto en el capítulo 2 pero adaptados al contexto de las herramientas colaborativas Web 2.0. Con el fin de facilitar la comprensión del modelo final, los factores se agrupan en cuatro tipos: tecnológicos, de control, socio-normativos y otros específicos de las herramientas colaborativas. En el capítulo 4 se lleva a cabo la relación de los factores que son más apropiados para estudiar la adopción de las herramientas colaborativas y se define un modelo que especifica las relaciones entre los diferentes factores. Estas relaciones finalmente se convertirán en hipótesis de trabajo, y que habrá que contrastar mediante el estudio empírico. A lo largo del capítulo 5 se especifican las características del trabajo empírico que se lleva a cabo para contrastar las hipótesis que se habían enunciado en el capítulo 4. La naturaleza de la investigación es de carácter social, de tipo exploratorio, y se basa en un estudio empírico cuantitativo cuyo análisis se llevará a cabo mediante técnicas de análisis multivariante. En este capítulo se describe la construcción de las escalas del instrumento de medida, la metodología de recogida de datos, y posteriormente se presenta un análisis detallado de la población muestral, así como la comprobación de la existencia o no del sesgo atribuible al método de medida, lo que se denomina sesgo de método común (en inglés, Common Method Bias). El contenido del capítulo 6 corresponde al análisis de resultados, aunque previamente se expone la técnica estadística empleada, PLS-SEM, como herramienta de análisis multivariante con capacidad de análisis predictivo, así como la metodología empleada para validar el modelo de medida y el modelo estructural, los requisitos que debe cumplir la muestra, y los umbrales de los parámetros considerados. En la segunda parte del capítulo 6 se lleva a cabo el análisis empírico de los datos correspondientes a las dos muestras, una para blogs y otra para wikis, con el fin de validar las hipótesis de investigación planteadas en el capítulo 4. Finalmente, en el capítulo 7 se revisa el grado de cumplimiento de los objetivos planteados en el capítulo 1 y se presentan las contribuciones teóricas, metodológicas y prácticas derivadas del trabajo realizado. A continuación se exponen las conclusiones generales y detalladas por cada grupo de factores, así como las recomendaciones prácticas que se pueden extraer para orientar la implantación de estas herramientas en situaciones reales. Como parte final del capítulo se incluyen las limitaciones del estudio y se sugiere una serie de posibles líneas de trabajo futuras de interés, junto con los resultados de investigación parciales que se han obtenido durante el tiempo que ha durado la investigación. ABSTRACT In the last two decades, the relevance of knowledge acquisition and dissemination processes has been highlighted and consequently, the study of these processes and the implementation of the technologies that make them possible has generated growing interest in the scientific community. In order to ease and optimize knowledge acquisition and dissemination, hierarchical organizations have evolved to a more horizontal configuration with more agile net structures, decreasing the dependence of a centralized authority, and building team-working oriented organizations. At the same time, Web 2.0 collaboration tools such as blogs and wikis have quickly developed. These collaboration tools are characterized by a strong social component and can reach their full potential when they are deployed in horizontal organization structures. Web 2.0, based on user participation, arises as a concept to challenge the existing technologies of the 90’s which were based on websites. Fortune 500 companies – HP, IBM, Xerox, Cisco- adopted the concept immediately even though there was no unanimity about its real usefulness or how it could be measured. This is partly due to the fact that the factors that make the drivers for employees to adopt these tools are not properly understood, consequently leading to implementation failure due to the existence of certain barriers. Given this situation, and faced with theoretical advantages that these Web 2.0 collaboration tools seem to have for companies, managers and the scientific community are showing an increasing interest in answering the following question: Which factors contribute to the decision of the employees of a company to adopt the Web 2.0 tools for collaborative purposes? The answer is complex since these tools are relatively new in business environments. These tools allow us to move from an information Management approach to Knowledge Management. In order to answer this question, the chosen approach involves the application of technology adoption models, all of them based on the individual’s perception of the different aspects related to technology usage. From this perspective, this thesis’ main objective is to study the factors influencing the adoption of blogs and wikis in a company. This is done by using a unified and theoretical predictive model of technological adoption with a holistic approach that is based on literature of technological adoption models and the particularities that these tools presented under study and in a specific context. This theoretical model will allow us to determine the factors that predict the intended use of these tools and their real usage. The scientific research is structured in five parts: Introduction to the research subject, development of the theoretical framework, research work design, empirical analysis and drawing the final conclusions. This thesis develops the five aforementioned parts sequentially thorough seven chapters; part one (chapter one), part two (chapters two and three), part three (chapters four and five), parte four (chapters six) and finally part five (chapter seven). The first chapter is focused on the research problem statement and the objectives of the thesis, intended to be reached during the project. Likewise, the concept of collaboration and its link with the Web 2.0 collaborative tools is discussed as well as an introduction to the technology adoption models. Finally we explain the planning to carry out the research and get the proposed results. After introducing the research topic, the second chapter carries out a review of the evolution of the main existing technology adoption models (IDT, TRA, SCT, TPB, DTPB, C-TAM-TPB, UTAUT, UTAUT2), highlighting its foundations and factors used. Based on technology adoption models set out in chapter 2, the third chapter deals with the factors which have been discussed previously in chapter 2, but adapted to the context of Web 2.0 collaborative tools under study, blogs and wikis. In order to better understand the final model, the factors are grouped into four types: technological factors, control factors, social-normative factors and other specific factors related to the collaborative tools. The first part of chapter 4 covers the analysis of the factors which are more relevant to study the adoption of collaborative tools, and the second part proceeds with the theoretical model which specifies the relationship between the different factors taken into consideration. These relationships will become specific hypotheses that will be tested by the empirical study. Throughout chapter 5 we cover the characteristics of the empirical study used to test the research hypotheses which were set out in chapter 4. The nature of research is social, exploratory, and it is based on a quantitative empirical study whose analysis is carried out using multivariate analysis techniques. The second part of this chapter includes the description of the scales of the measuring instrument; the methodology for data gathering, the detailed analysis of the sample, and finally the existence of bias attributable to the measurement method, the "Bias Common Method" is checked. The first part of chapter 6 corresponds to the analysis of results. The statistical technique employed (PLS-SEM) is previously explained as a tool of multivariate analysis, capable of carrying out predictive analysis, and as the appropriate methodology used to validate the model in a two-stages analysis, the measurement model and the structural model. Futhermore, it is necessary to check the requirements to be met by the sample and the thresholds of the parameters taken into account. In the second part of chapter 6 an empirical analysis of the data is performed for the two samples, one for blogs and the other for wikis, in order to validate the research hypothesis proposed in chapter 4. Finally, in chapter 7 the fulfillment level of the objectives raised in chapter 1 is reviewed and the theoretical, methodological and practical conclusions derived from the results of the study are presented. Next, we cover the general conclusions, detailing for each group of factors including practical recommendations that can be drawn to guide implementation of these tools in real situations in companies. As a final part of the chapter the limitations of the study are included and a number of potential future researches suggested, along with research partial results which have been obtained thorough the research.
