Feasibility of using network support data to predict risk level of trouble tickets

Laurentz, Henrik January 2016 (has links)
Internet Service Providers gather vast amounts of data in the form of trouble tickets created from connectivity related issues. This data is often stored and seldom used for proactive purposes. This thesis explores the feasibility of finding correlations in network support data through the use of data mining activities. Correlations such as these could be used for improving troubleshooting or staffing related activities. The approach uses the data mining methodology CRISP-DM to investigate typical data mining operations from the perspective of a Network Operation Center. The results show that correlations between the solving time and other ticket related attributes do exist and that support data could be used for the activities mentioned. The results also show that it exists a lot of room for improvement when it comes to data mining activities in network support data.

Social network influence on relational termination and renewal

Hansen, Ryan Nicholas 24 March 2014 (has links)
This study’s focus was on individuals who are currently in romantic relationships or who were in one within the past six months. The goal of the study was to learn more about the relationship between the perceived difficulty of renewing a recently terminated relationship or terminating a current romantic relationship and social network closeness, integration, and levels of perceived support for the relationship from network members. The findings for this study support the prediction that an individual’s perceived difficulty of terminating an intact relationship was positively related to their levels of closeness with their partner’s social network members, the individual’s partner’s closeness with the individual’s social network members, and the perceived support for the relationship from network members. / text

Por isso, a assistência para comunidades de usuários que tem dificuldades em usar a rede tem sido identificada como uma das principais questões de suporte relacionadas ao desempenho. Isso explica a crescente demanda por serviços de monitoramento que tentam auxiliar os usuários no entendimento das propriedades de rede, bem como no uso de suas aplicações. Serviços de monitoramento trouxeram grandes benefícios em termos de suporte aos usuários. Mesmo assim, existe uma carência por serviços de aconselhamento que beneficie os usuários com informações que vão além da simples apresentação das propriedades de rede. Atualmente, tanto usuários avançados quanto equipes de suporte contam com ferramentas que apresentam informações de uma perspectiva puramente técnica. A maioria delas se baseiam em informações obtidas como resultado de atividades de monitoramento, independentemente dos níveis de qualidade de serviços percebidos pelos usuários. Tais ferramentas de medição atendem razoavelmente os requisitos dos gerentes, operadores e usuários finais quando se trata de aplicações comuns. Contudo, a comunidade de pesquisa vem destacando a importância da qualidade de experiência (QoE) durante a avaliação dos serviços de rede quando se trata de aplicações avançadas. Ao considerar as opiniões dos usuários, o gerenciamento da qualidade de serviços torna-se mais efetivo, uma vez que a avaliação do serviço não está restrita às considerações da equipe de suporte e gerenciamento. Essa tese apresenta uma abordagem de aconselhamento para o suporte de usuários de rede que foca na colaboração entre usuários através do compartilhamento das suas experiências no uso das aplicações para construir uma base de conhecimento. O conhecimento representado inclui não somente a informação sobre os problemas de desempenho, como também as características as aplicações e as opiniões dos usuários. Através dessas características, a abordagem procura alcançar altos níveis de satisfação dos usuários pela redução gradual do volume de informações de suporte erradas. Para avaliar a viabilidade dessa abordagem, um modelo de sistema de raciocínio baseado em casos (RBC) foi construído e validado através de um estudo experimental conduzido em laboratório por meio de um sistema multiagente. O sistema é apoiado por uma base de conhecimento baseada no uso de ontologias e um esquema de reputação baseado no algoritmo Pagerank. Os resultados do estudo mostraram a efetividade da abordagem proposta, sua resilência à comportamento de usuários incoerentes e em conluio, e a importância do conhecimento do domínio sobre as atividades de suporte a usuários

Conflict and cortisol in newlyweds’ natural environments : the stress-buffering role of perceived network support

Keneski, Elizabeth Rose 19 March 2014 (has links)
Relationship conflict is robustly linked to negative physiological responses that have serious implications for partners’ overall physical health. The link between relationship conflict and physiological reactivity, however, has been studied almost exclusively in a laboratory setting. The first aim of this study was to assess the link between conflict and physiological function in couples’ home environments. Newlywed spouses reported occurrences of marital conflict in a daily diary and concurrently provided morning and evening saliva samples for the calculation of daily diurnal cortisol slopes. Spouses experienced less steep (i.e., less healthy) diurnal cortisol slopes on days of greater marital conflict. The second aim of this study was to examine whether spouses’ connections with close others outside their marriages (i.e., quantity and quality of perceived network support) moderate physiological responses to marital conflict. Whereas the quantity of network support did not influence spouses’ responses to conflict, the quality of spouses’ network support attenuated the association between daily marital conflict and diurnal cortisol. Specifically, whereas those spouses who were less satisfied with their network support experienced less steep diurnal cortisol on days of greater marital conflict, those spouses who were more satisfied with their network support exhibited no effects of daily marital conflict on diurnal cortisol. Implications for maintaining quality social relationships outside a marriage are discussed. / text

No. of bitstreams: 1 Marla Pereira Martins_.pdf: 1000517 bytes, checksum: 6740f5df3b25df5cfa41ca73f6b68a60 (MD5) Previous issue date: 2015-04-17 / Nenhuma / O objetivo da presente pesquisa foi avaliar o bem-estar psicológico (BEP) de um grupo de bancários aposentados e verificar a relação do BEP, com o fato de ter feito alguma ação de preparação para a aposentadoria, com o tipo de apoio social e com a importância dada a alguns fatores-chave para o planejamento da aposentadoria. A coleta de dados foi realizada via internet, por meio de um questionário auto-aplicado, sobre dados sociodemográficos, ações de planejamento para a aposentadoria, a Escala de Bem-estar Psicológico, o Questionário Medical Outcomes Study Social Support Survey e a Escala dos fatores-chave de planejamento para a aposentadoria. Participaram da pesquisa 200 bancários aposentados, sendo 68% homens e 32% mulheres que constituíram carreiras e se aposentaram em uma instituição financeira pública e/ou de economia mista no Rio Grande do Sul. Os dados obtidos foram organizados em dois artigos empíricos. O primeiro apresenta a descrição dos participantes e a relação dos fatores de BEP com as características sociodemográficas do grupo estudado. Os resultados apontaram que a participação em associações e/ou grupo de aposentados, ter um trabalho voluntário e ter um trabalho remunerado na aposentadoria foram às características sociodemográficas que apresentaram relação significativa com BEP. O segundo artigo apresenta a relação entre fatores de BEP, ações de planejamento para a aposentadoria, apoio social e fatores-chave para a preparação para a aposentadoria, buscando identificar quais destes fatores são preditores do BEP. Verificou-se que 32% do BEP pode ser explicado por cinco das variáveis estudadas, estando entre elas: o fator interação social positiva, o fator bem-estar pessoal e social e ter um projeto de vida, participação de cursos e/ou palestras e prática de atividade física. Destaca- se que os resultados dos dois estudos reforçam a importância de se pensar e planejar a fase da aposentadoria para que esta etapa de vida seja usufruída com melhores índices de bem-estar psicológico. / The aim of this research was to evaluate the psychological well-being (BEP) of a group of bank retirees and verify the relation of the BEP and the fact of any preparation action for the retirement done, with the sort of social support and the importance given to some key-factors for the retirement planning. The data collection was performed via internet, through an online self applied questionnaire, about sociodemographic data, planning actions for retirement, the Psychological Well-being Scale, the Medical Outcomes Study Social Support Survey Questionnaire and the Scale of the Key Factors for Retirement Planning. The research participants were 200 bank retirees, 68% men and 32% women who build their career and retired in a public financial institution and/or with mixed economy at the Rio Grande do Sul state. The collected data were organized in two empirical articles. The first one presents the participants description and the relation of the BEP and the sociodemographic characteristics of the studied group. The results pointed that the participation on associations and/or retirees groups, to have a volunteer work and to have a paid work during the retirement were the characteristics who shown significant relation with the BEP. The second article presents the relation between the BEP factors, retirement planning actions, social support and key factors for retirement preparation, aiming to identify which of those factors are BEP predictor`s factors. The findings show that 32% of the bank retirees well-being who participated on this study, can be explained for five of the studied variables, between those: the positive social interaction factor, the personal e social well-being and to have a life project, participation on courses and/or lectures and physical activity practice. Stands out that the results of the two studies reinforce the importance to think and plan the retirement phase so this period of life can be enjoyed with better level of psychological well being.

No. of bitstreams: 1 Maura Castello Bernauer.pdf: 7675428 bytes, checksum: 434d3045e21d934d3a6c6cff242b77d3 (MD5) Previous issue date: 2013-11-29 / The role of the individual in response to health loss doesn t occur passively; strategies are often unknown to healthcare services, which motivate the search for care. It s common belief that social groups establish supportive relationships, forming networks that define therapeutic practices and caring itineraries, and collaborating in coping with everyday life situations. The objective of this research is to investigate how the Social Network Support interferes in the configuration of Therapeutic Itinerary and Self-caring Health of men and women using the Healthcare System in Baixada Santista, São Paulo, Brazil. Gender Relations are taken as a basis when considering that therapeutic itineraries and gender issues are analytical categories that can help in the apprehension of processes associated to self-care health adhesion and also promote population`s citizenship and autonomy as well as their role in their daily lives. As an epistemological reference this study has a dialectical historical materialistic conception under the perspective of Sociohistorical Psychology. The listed categories will enable us to obtain information on practices and knowledge that integrate the Social Network Support and to understand selection processes that define their therapeutic itineraries. The Therapeutic Itineraries represent the access to the meanings of self-care process, aiming to grasp how individuals act in relation to their own malaise in search for solutions both in the traditional medical clinics and in their social network through the sharing of beliefs and practices that express their personal sense of health and illness process. Methodologically, the research is evaluative and transforming in its own field data collection, having been developed in three fronts: through live interviews, audio recorded, with open and closed questions, in a Family Health Unit (USF) in the north-west region of Santos, SP; at a public place (square, beach, restaurant, newsstand etc.); and over the Internet (web) with healthy men and women living in cities of Baixada Santista. This study sample consisted of 102 users of healthcare public and private systems, aged above 17 years. The qualitative data analysis made use of the categories social network support, therapeutic itineraries and self-care inserted in the Sphinx Brazil program. For the quantitative analysis we used clusters by means of the SPSS (Social Package for Social Sciences) software. The methodology chosen amplifies the concept of traditional researches as it involves active listening of the population, promotes the search for detailed information about real life situations, and encourages self-criticism by incorporating social actors` opinion. As a consequence, it intends to stimulate awareness in the sense that each individual is the subject of his own history, capable of making decisions on his options / O papel do indivíduo frente aos agravos de saúde não ocorre passivamente; existem estratégias, muitas vezes desconhecidas pelos serviços de saúde, que motivam a busca de cuidados. Acredita-se que os grupos sociais estabelecem relações de apoio, compondo redes que definem práticas terapêuticas e itinerários de cuidado e colaborando no enfrentamento de situações de vida cotidianas. O objetivo desta pesquisa é investigar como a Rede de Apoio Social interfere na configuração do Itinerário Terapêutico e do autocuidado em saúde de homens e mulheres usuários do Sistema de Saúde da Baixada Santista SP. Toma-se como base as Relações de Gênero, acreditando que os itinerários terapêuticos e as questões de gênero são categorias analíticas que podem auxiliar na apreensão dos processos associados à adesão ao autocuidado em saúde e promover a cidadania e a autonomia da população, bem como o protagonismo no seu dia a dia. Este estudo tem como Referencial Epistemológico a concepção materialista histórica dialética com base na perspectiva da Psicologia sócio-histórica. Os Itinerários Terapêuticos representam a via de acesso aos significados do processo de autocuidado, com vistas ao entendimento de como agem os sujeitos em relação ao seu mal-estar na busca por soluções tanto em clínicas médicas tradicionais quanto em sua rede social via compartilhamento de crenças e práticas que expressam seu sentido pessoal do processo saúde e doença. As categorias elencadas possibilitarão obter informações sobre práticas e saberes que integram a Rede de Apoio Social das pessoas e compreender os processos de escolha que desenham seus itinerários terapêuticos. Metodologicamente, a pesquisa é avaliativa e transformadora em seu próprio campo de coleta de dados, tendo sido desenvolvida em três frentes: por meio de entrevistas presenciais, gravadas em áudio, com questões abertas e fechadas, em uma Unidade Saúde da Família USF da Zona Noroeste da cidade de Santos; em Local Público (praça, praia, restaurante, banca de jornal etc.), e pela Internet (web) com homens e mulheres saudáveis, residentes em cidades da Baixada Santista. A amostra do estudo foi composta por 102 usuários do Sistema Público e Privado de saúde, com idade acima de 17 anos. A análise qualitativa dos dados fez uso das categorias rede de apoio social, itinerários terapêuticos, e autocuidado, inseridos no programa Sphinx Brasil. Para a análise quantitativa foram utilizados os conglomerados Clusters, do software SPSS (Social Package for Social Sciences). A metodologia adotada amplia a concepção das pesquisas tradicionais , pois envolve uma escuta ativa da população, promove a busca de informações minuciosas sobre suas situações de vida e estimula a autocrítica por meio da incorporação do olhar de atores sociais. Em consequência, pretende incentivar o protagonismo no sentido de que cada pessoa seja o sujeito de sua própria história, com capacidade de decisão sobre suas opções

Föräldrar som har förlorat ett barn under perinatalperioden : en kvalitativ studie om föräldrars upplevelser av bemötande, stöd och hjälp / Parents who have lost a child during the perinatal period : a qualitative study of parents' experiences of how they are treated, support and help

Rönnbrink, Frida January 2010 (has links)
Sammanfattning Av: Frida Rönnbrink Föräldrar som har förlorat ett barn under perinatalperioden – en kvalitativ studie om föräldrars upplevelser av bemötande, stöd och hjälp Studien syftade till att utifrån sex föräldrars berättelser, nå en ökad förståelse om hur de upplever bemötandet, stödet och hjälpen då de förlorat ett barn under perinatalperioden. Studien hade följande frågeställningar: Hur upplever föräldrar, som har förlorat sina barn under perinatalperioden, det bemötande och det stöd och den hjälp de fått från professionella? Hur upplever de det sociala nätverkets bemötande och stöd? För att besvara frågorna utgick intervjun från tre teman, professionellt bemötande, professionellt stöd och hjälp samt det egna sociala nätverket. Studien gjordes med en fenomenologisk vetenskapsfilosofisk position. Resultatet analyserades manuellt och tolkades hermeneutiskt med hjälp av kristeori, systemteori samt Vaux teori om socialt stöd. Studiens resultat visade att de föräldrar som nyligen förlorat sitt barn var relativt nöjda med den professionella hjälpen. Däremot kunde man se klara brister i det egna sociala nätverkets stöd. Nyckelord: Föräldrars upplevelser, perinatal död, bemötande, professionellt stöd, nätverkets stöd. / Abstract By: Frida Rönnbrink Parents who have lost a child during the perinatal period - a qualitative study of parents' experiences of how they are treated, support and help The purpose of the study was to reach a better understanding of how six parents experience how they were treated, supported and helped when they lost a child during the perinatal period. This can then be used to customize the help offered them. The study had the following questions: How do parents who have lost a child during the perinatal period, experience how they are treated and the support and help they received from professionals? And, how do they experience the social network's treatment and support? In order to answer the questions, the interview was based on three themes, professional treatment, professional support and help and support from the network on their own. The study was conducted using a phenomenological philosophical position. The results were analyzed manually and were interpreted hermeneutic using crisis theory, systems theory and Vaux's theory of social support. The results showed that parents who recently lost their infant were relatively pleased with the professional help. However, you could see deficiencies in their own social network support. Keywords: Parents' experiences, perinatal death, treatment, professional support, network support.

No. of bitstreams: 1 Danielly Bart do Nascimento.pdf: 1087921 bytes, checksum: b861e5660ca87dc55ce0ed9c57257216 (MD5) Previous issue date: 2011-06-20 / Coordenação de Aperfeiçoamento de Pessoal de Nível Superior / Esta pesquisa possui como objetivo avaliar o Serviço de Proteção e Atendimento Especializado a Famílias e Indivíduos (PAEFI) enquanto participante da rede de apoio social e afetiva de crianças por ele acompanhadas. A avaliação é feita a partir da percepção de ambas, profissionais e crianças atendidas. O intuito é disponibilizar dados que ajudem a fomentar as políticas públicas e as práticas dos profissionais de Serviços voltados para este público. Participaram da pesquisa duas crianças, um menino e uma menina, com idades de 10 e 11 anos respectivamente, os seus responsáveis (os pais e as mães), uma Psicóloga e uma Assistente Social do PAEFI que os acompanharam. Os dados foram coletados por meio de entrevistas, análise de prontuários, aplicação do Mapa dos Cinco Campos e observações que foram registradas em um diário de campo. As observações foram facilitadas pelo método de Inserção Ecológica e a Teoria Bioecológica do Desenvolvimento Humano foi utilizada na discussão dos dados. Como principais resultados, encontramos o Serviço como parte da rede de apoio social e afetiva na percepção da menina, enquanto o menino não o percebeu da mesma maneira. A distinção entre os resultados dependeu de como as crianças perceberam e lidaram com o ambiente e as relações estabelecidas entre as pessoas. Além disso, fatores relacionados à estrutura do Serviço têm dificultado sua atuação. Dessa forma, o estudo indicou a necessidade de mais investimentos em sua infraestrutura, desde o ambiente físico à formação dos profissionais que nele trabalham / The present study aims to evaluate the effectiveness of the Service for Protection and Specialized Assistance to families and individuals (PAEFI) Program as part of the social and affective support network, from the viewpoint of both the assisted children and the professionals who assist them. It is hoped that the research can provide data which may foster public policies as well as the practices of those involved in programs which deal with this type of audience. Two children (a boy and a girl of ten and eleven years old respectively), their parents, the social assistant and the psychologist who assisted them in the PAEFI participated in the research. Data were collected by means of interviews, analysis of records, application of the Five Field Map, observations and field diaries. The observations were facilitated by the Ecological Insertion method whereas the Bioecological Model for human development was applied for the discussion of results. Results indicated that the program was perceived by the girl as part of the social and emotional support network, but not by the boy. This difference may be due to the way children perceived and dealt with the environment, and to the type of relationship established. It was also evidenced that factors related to the structure of the program have hampered its performance. Therefore, the study indicated the need for more investments in the PAEFI s infrastructure from the physical environment to the training of those professionals who are part of it

Evaluation of Three Machine Learning Algorithms for the Automatic Classification of EMG Patterns in Gait Disorders

Fricke, Christopher, Alizadeh, Jalal, Zakhary, Nahrin, Woost, Timo B., Bogdan, Martin, Classen, Joseph 27 March 2023 (has links)
Gait disorders are common in neurodegenerative diseases and distinguishing between seemingly similar kinematic patterns associated with different pathological entities is a challenge even for the experienced clinician. Ultimately, muscle activity underlies the generation of kinematic patterns. Therefore, one possible way to address this problem may be to differentiate gait disorders by analyzing intrinsic features of muscle activations patterns. Here, we examined whether it is possible to differentiate electromyography (EMG) gait patterns of healthy subjects and patients with different gait disorders using machine learning techniques. Nineteen healthy volunteers (9 male, 10 female, age 28.2 ± 6.2 years) and 18 patients with gait disorders (10 male, 8 female, age 66.2 ± 14.7 years) resulting from different neurological diseases walked down a hallway 10 times at a convenient pace while their muscle activity was recorded via surface EMG electrodes attached to 5 muscles of each leg (10 channels in total). Gait disorders were classified as predominantly hypokinetic (n = 12) or ataxic (n = 6) gait by two experienced raters based on video recordings. Three different classification methods (Convolutional Neural Network—CNN, Support Vector Machine—SVM, K-Nearest Neighbors—KNN) were used to automatically classify EMG patterns according to the underlying gait disorder and differentiate patients and healthy participants. Using a leave-one-out approach for training and evaluating the classifiers, the automatic classification of normal and abnormal EMG patterns during gait (2 classes: “healthy” and “patient”) was possible with a high degree of accuracy using CNN (accuracy 91.9%), but not SVM (accuracy 67.6%) or KNN (accuracy 48.7%). For classification of hypokinetic vs. ataxic vs. normal gait (3 classes) best results were again obtained for CNN (accuracy 83.8%) while SVM and KNN performed worse (accuracy SVM 51.4%, KNN 32.4%). These results suggest that machine learning methods are useful for distinguishing individuals with gait disorders from healthy controls and may help classification with respect to the underlying disorder even when classifiers are trained on comparably small cohorts. In our study, CNN achieved higher accuracy than SVM and KNN and may constitute a promising method for further investigation.

Perceived Social Support for Relationships As a Predictor of Relationship Well-Being and Mental and Physical Health in Same-Sex and Mixed-Sex Relationships: A Longitudinal Investigation

BLAIR, Karen Lyndsay 30 May 2012 (has links)
Intimate relationships function not in isolation, but within a broader social network and social environment, in which the opinions and actions of close network members can play a role in how a relationship develops. The current study investigated how perceiving support for one’s relationship (including same-sex and mixed-sex relationships) from friends and family is associated with not only relationship well-being, but also the mental and physical health of the individuals within the relationship. After establishing that social support specifically for a relationship was indeed a separate and unique construct as compared to more general social support for an individual, the study tested a hypothesized model using structural equation modeling, finding evidence for a model in which the association between support for a relationship and the health outcomes for an individual is fully mediated by relationship well-being. Relationship type (i.e., same-sex versus mixed-sex) was not a significant moderator, indicating that regardless of relationship type, individuals who perceive more support for their relationship are also more likely to report greater relationship satisfaction and better mental and physical health. Furthermore, participants provided data up to three times over a period of three years, allowing for an examination of how social support for a relationship functions as a predictor of relationship well-being and health outcomes over time. Perceived social support for a relationship at Time 1 was found to be a significant predictor of the rate of relationship dissolution over the course of the study as well as relational and health outcomes at later points in time. With respect to the source of support for the relationship, evidence was found that support from parents and friends both have associations with relationship outcomes, but these findings were inconsistent across analyses with support from parents having stronger associations in some analyses and support from friends having stronger associations in others. Reasons for these discrepancies are discussed, as well as theoretical implications concerning the role that perceived social support for relationships plays in the prediction of relationship well-being and mental and physical health. / Thesis (Ph.D, Psychology) -- Queen's University, 2012-05-29 21:04:59.381
