A Descriptive Comparison of Value System Analysis and the Personal Orientation Inventory

Scoggin, George R. 08 1900 (has links)
The purpose of this study was to determine the correlation between the Values for Working Test and the Personal Orientation Inventory. Both instruments were administered to the same group of 232 employed individuals. Stepwise multiple linear regression with analysis of variance was the statistical procedure employed. The resulting correlations were high enough to determine directionality and order of selection. The data indicates much support for Clare Graves' theory of value systems. Additional research is needed to further validate the Values for Working Test.

Criterion Validity of the MMPI-2 in a State Hospital Setting

Connell, Richard (Richard Nicholas), 1965- 08 1900 (has links)
The current study investigated the criterion validity of the Minnesota Multiphasic Personality Inventory - 2 (MMPI-2) by comparing participants' profiles with other variables, including diagnosis, length of hospitalization, and chronicity. The specific diagnostic groups investigated were depressed (major depressive disorder; dysthymic disorder; and bipolar disorder, depressed), schizophrenic (schizophrenia, schizophreniform disorder, and schizoaffective disorder), and borderline personality disorder (BPD). Statistical analyses included use of univariate analyses of variance (ANOVAs), multivariate analyses of variance (MANOVAs), regression analyses, and measures of sensitivity, specificity, positive predictive power (PPP), and negative predictive power (NPP). MANOVA results indicated significant differences between diagnostic groups on Scales F, 2, 3, 4, 7, ANX. FRS. DEP. BIZ. M f i , LSE, and FAM. There were considerable differences between males and females when separate MANOVAs were performed for gender groups. Cutoff see ires for classification by diagnosis resulted in significant specificity rates and negative predictive power, but sensitivity rates and positive predictive power were not significant.

Syndrom vyhoření - diagnostické možnosti (srovnávací studie) / Burnout syndrome - diagnostic possibilities (comparative study)

Vlachovská, Barbora January 2011 (has links)
The theoretical part deals with key issues of burnout - a definition, phase of syndrome, diagnostic classification, prevention, and mainly deals with the description of the methods by which the level of burnout is detected. Now probably the most common diagnostic tools are the MBI (Maslach Burnout Inventory) and its derivatives (eg. MBI-General Survey), but there are many other methods, such as developed by Israeli and European psychologists (BoTeLis, OLBI, CBI, MBS, etc.). The goal is to assemble a relatively complete overview of these diagnostic tools.In the empirical part, is to verify the psychometric properties of Czech version of the selected methods on a set of population, describe and analyze their characteristics.

Effektiviserad lagerhantering av reservdelar för minskad kapitalbindning

Karlsson, Madelene, Hagevall, Sandra January 2019 (has links)
Spare parts are, for many companies, a complex product to logistically handle. This is in part due to the varying characteristics and sporadic demand patterns of spare parts. Obstacles can often arise when companies utilize the same approach to their spare parts stock as they do with their general warehouse manufacturing inventory. By using the same approach, companies risk neglecting the widespread variation of the spare parts. With the help of established routines, a clear set of guidelines and factors, the chances of a successful handling of spare parts inventory is increased. The study is a qualitative case study with the purpose of identifying specific factors and to make recommendations of models for companies to take into account when evaluating and storing spare parts. Through unstructured/semi-structured interviews conducted with four case company employees, information was gathered which was used to assist in identifying these specific factors and models for companies. A theoretical frame of reference was produced through analyzing research articles and was compared to the compiled empirical data in an analysis. The departments within the case study based their work on single factor which were considered important for each specific department, without inter-departmental communication. The factors that were identified in the study include service, competitive advantage, tied up capital, size capacity, complexity, sales frequency and material. Four of these were considered to be a priority for the case company. The study showed that different models for spare parts management and outsourcing could be implemented in the case company. By integrating the different models for spare parts management and outsourcing, combined with communication, a new model has been proposed for handling the spare parts storage. / Reservdelar är för många företag en komplex produkt att hantera utifrån dess varierande egenskaper och sporadiska efterfrågemönster. Problematiken härstammar ofta från att många företag hanterar reservdelslager utifrån samma förutsättningar som dess allmänna lagerhantering, därigenom försummas reservdelarnas olika egenskaper. Förutbestämda riktlinjer och faktorer krävs vid hantering av reservdelar och en viktig komponent för att lyckas med detta är kommunikation. Arbetet är en kvalitativ fallstudie med syftet att ta fram faktorer och rekommendationer av modeller att ta hänsyn till vid värdering och lagerhantering av reservdelar. För att besvara syftet och frågeställningarna utfördes ostrukturerade/semistrukturerade intervjuer med fyra medarbetare på fallföretaget. En teoretisk referensram togs fram genom litteratursökningar som sedan ställdes i en jämförelse mot den sammanställda empirin i en analys. Studien visade att de olika avdelningarna på fallföretaget främst utgått från en enda faktor som ansetts vara viktig för den specifika avdelningen. Utifrån de framtagna faktorerna i studien; service, konkurrensfördel, kapitalbindning, fyllnadsgrad, komplexitet, försäljningsfrekvens och material, ansågs fyra av dessa vara av prioritet för fallföretaget. Studien visade att olika modeller för reservdelshantering och outsourcing skulle kunna implementeras på fallföretaget. Genom att integrera de olika modellerna för reservdelshantering och outsourcing, kombinerat med kommunikation, har en ny modell föreslagits för hantering av reservdelslager.

Instrumentation du « transshipment d’urgence » comme mode de coopération pour l’amélioration du pilotage des flux dans les réseaux de distribution / Use of emergency transshipment as a mode of cooperation for improving the management of flows in distribution networks

Ben Hamida, Mounira 02 July 2011 (has links)
Le « transshipment (latéral) d’urgence » au sein des réseaux de distribution consiste à organiser les transferts de stocks entre les détaillants pour faire face aux situations de rupture. Sa mise en œuvre amène à arrêter une stratégie appropriée et à harmoniser ses paramètres avec la politique et paramètres de gestion des stocks, dans l’objectif de garantir un taux de satisfaction des demandes clients au moindre coût. Le présent travail se situe dans ce contexte et s’est focalisé sur l’analyse des apports de la mise en œuvre du transshipment d’urgence dans un système de pilotage de flux tirés par des demandes clients probabilistes, avec des politiques locales de gestion de stock du type (R, s, S). Notre étude a porté sur trois structures différentes de réseau : système de stock à deux échelons et à deux détaillants, avec coût unitaire de transshipment ; système de stock à deux échelons et à détaillants multiples, avec coût fixe de transshipment ; système de stock multi échelons à deux détaillants, avec coût fixe de transshipment. Pour chacune de ces structures, nous avons analysé le comportement du système pour différentes combinaisons des paramètres d’entrée (délais d’approvisionnement, écarts types de la demande et nombre des détaillants) et des paramètres de coût (commande, possession, rupture et transshipment). Nous avons visé à déterminer, sur un horizon fini de périodes, les seuils de stocks (s et S chez les détaillants et chez le centre de distribution) qui minimisent le coût total du système tout en garantissant un taux de service désiré. Dans ce cadre, quatre politiques de transshipment (« tout ou rien », « complete pooling standard », « complete pooling plafonné » et « complete pooling conditionné ») ont été explorées. L’étude est d’abord ébauchée selon une approche analytique puis approfondie par l’élaboration et l’expérimentation de modèles dont la résolution est basée sur la simulation-optimisation / The lateral emergency transshipment in distribution systems consists in organizing inventory transferts between retailers to face shortage situations. Its implementation leads to adopt an appropriate transhipment policy and harmonize its parameters with inventory policy parameters and inventory control policy. The objective is to ensure a desired service level at minimum cost. Thie work is situated in this context and focused on the analysis of emergency transhipment benefits in distribution systems faced to random customers demand. Each retailer used an (R,s,S) inventory control policy. Our study is related to three different distribution systems structure : two echelons two retailers inventory system with unit transhipment cost; two echelons multi retailers inventory system with fixed transhipment cost; multi echelons multi retailers inventory system with fixe transhipment cost. For each of these structures we analyzed the sensibility of system behaviour to input parameters. Our objective is to determine on a finite horizon the inventory parameters (s, S) that minimize total cost under service level condition.

Desenvolvimento de um modelo de simulação para avaliação do desempenho de uma cadeia de suprimentos multicamadas do ramo de mineração através da adoção da estratégia colaborativa VMI (Vendor Managed Inventory). / Development of a simulation model to evaluate the performance of a mining industry supply chain using the collaborative strategy VMI(Vendor Managed Inventory).

Silva, Gabriel Rossoni 15 April 2010 (has links)
No presente trabalho é proposto um modelo de simulação de uma cadeia de suprimentos integrada com adoção da estratégia de VMI (Vendor Managed Inventory) entre uma empresa do setor de minério de ferro e alguns de seus fornecedores estratégicos. O modelo baseia-se em uma estrutura de avaliação de sistemas VMI adaptada de Sarpola et al. (2007) em conjunto com as configurações de cadeias de suprimentos propostas por Holmström et al (2003), o que permite medir o desempenho da cadeia de suprimentos segundo 3 níveis de integração. É feita uma revisão bibliográfica dos conceitos da estratégia de VMI, políticas de estoque em sistemas integrados, compartilhamento e grau de visibilidade de informações ao longo da cadeia de suprimentos. Os resultados obtidos possibilitam realizar uma análise quantitativa dos benefícios do VMI, onde são considerados demanda estocástica, lead time aleatório, produtos com características diferentes, compartilhamento de informações, visibilidade parcial da cadeia de suprimentos, lotes variáveis, cálculo dos estoques de segurança considerando informações dos pedidos, demanda real do cliente e erros de previsão. / In this paper we proposed a simulation model of an integrated supply chain with the adoption of VMI (Vendor Managed Inventory) strategy between a company of the iron ore and some of its strategic suppliers. The model is based on a framework for evaluating VMI systems adapted from Sarpola et al. (2007) together with the configurations of supply chains proposed by Holmström et al (2003), which measures the performance of the supply chain using 3 levels of integration. It is a literature review of the concepts of the strategy of VMI, inventory policies in integrated systems, sharing and degree of visibility of information throughout the supply chain. The results allowed to perform a quantitative analysis of the benefits of VMI, which are considered as stochastic demand, random lead time, products with different characteristics, information sharing, partial visibility of the supply chain, lots of variables, calculation of safety stocks based on information from client orders, actual customer demand and forecasting errors.

Methods: A before and after clinical assay was conducted with patients 17 years old or older who were included in the study after signing formal consent. Individuals answered, on their first interview, the Beck Depression Inventory (BDI) and the Beck Anxiety Inventory (BAI) and a pattern questionnaire about demographic and social-economic factors. Information regarding their illness and current medication was withdrawn from medical charts. At the end of their follow-up, patients answered again the BDI and the BAI. Patients initially classified as presenting minimum, mild, moderate or severe levels of depression and anxiety had their initial and final mean scores evaluated. Results: We included 64 HIV/AIDS patients in this study. The mean age (±SD) was 36 years (9,3). The mean time (±SD) between the first and second interview was 14 days (8,9). All depression levels and mild and moderate categories of anxiety presented reductions in scores with statistical significance (p< 0,05). Mean improvement of initial and final BDI scores was 7.03 points (95% CI 5,51-8,55) and for BAI scores, 6,23 points (95%CI 4,10-8,37). Conclusions: This study identified a favourable impact of the day-hospital clinic on HIV/AIDS patients emotional state without psychotherapeutic intervention. / Objetivo: Determinar impacto das intervenções um Hospital-Dia no estado emocional de pacientes HIV/AIDS atendidos no Hospital-Escola da Universidade Federal de Pelotas.

Moreover, how they deal with the risks of its fast obsolescence. The fastest alterations in fashion tendencies; the capacity or not to anticipate, identify and answer to changes in consumers?? tastes; the interruptions in the flow of goods, that could cause breaks in the supply chain; the growing competition; the unpredictability in consume, and planning errors upon the development of new collections could be harmful for stored products waiting for its customers ??? all of them force companies to charge prices lower than their costs. The user of financial statements needs to be warned of such risks, because they could affect the existing inventory. To reach the proposed aims, the practices adopted in the main international companies of this sector were analyzed, by means of published financial statements, and compared with those adopted by Brazilian companies listed in Bovespa Stock Exchange. In addition, through interviews, it was possible to identify the treatment given to the same theme by Brazilian companies unlisted in Bovespa Stock Exchange. It was clear that international and national listed companies correctly attend to what is established in accounting standards. On the other hand, in national unlisted companies, the adoption of these practices needs development. It was also possible to verify that financial statements of American companies provide their users with more details concerning risks involving operations with goods, when compared to information provided by European and Brazilian companies. / O objetivo deste estudo foi observar a forma pela qual as empresas atuantes no mercado da moda mensuram, avaliam e evidenciam seus estoques nas demonstra????es financeiras e de que maneira tratam os riscos de sua r??pida obsolesc??ncia. As mudan??as cada vez mais r??pidas nas tend??ncias de moda; a capacidade ou n??o de se antecipar, identificar e responder ??s altera????es nos gostos dos consumidores; as interrup????es no fluxo de mercadorias que podem causar rupturas no supply chain; o acirramento da concorr??ncia; a imprevisibilidade do consumo e, os erros de planejamento na elabora????o de novas cole????es podem ser danosos para os produtos estocados ?? espera de seus consumidores, obrigando as empresas a praticar pre??os muitas vezes inferiores ao seu pr??prio custo. O usu??rio das demonstra????es financeiras precisa ser informado a respeito desses riscos, pois estes podem impactar os estoques existentes. Para alcan??ar os objetivos propostos, foram analisadas, por meio das demonstra????es financeiras publicadas, as pr??ticas cont??beis adotadas nas principais empresas internacionais desse segmento, comparando-as ??quelas adotadas pelas empresas brasileiras, listadas na Bovespa. Complementarmente, atrav??s de entrevistas, buscou-se identificar o tratamento dado a esse mesmo tema pelas empresas brasileiras n??o listadas na Bovespa. Ficou claro que tanto as empresas internacionais, quanto as nacionais listadas, atendem corretamente ao que est?? estabelecido nas normas cont??beis, enquanto que nas empresas nacionais, de capital fechado, a ado????o dessas pr??ticas cont??beis, ainda carece de evolu????o. Pode ser observado, ainda, que as demonstra????es financeiras das empresas norte-americanas fornecem, aos seus usu??rios, mais detalhes a respeito dos riscos inerentes ??s opera????es com mercadorias, quando comparadas ??s informa????es fornecidas pelas empresas europeias e brasileiras.

Gestão dos estoques numa cadeia de distribuição com sistema de reposição automática e ambiente colaborativo. / Multi-echelon inventory management with automatic replenishment program and collaborative environment.

Dias, George Paulus Pereira 01 July 2003 (has links)
O foco dessa dissertação está na gestão de estoques em sistemas multicamadas. O modelo de simulação construído considera o desempenho histórico de uma cadeia de distribuição de medicamentos versus a política de gestão proposta. Os objetivos principais do trabalho são: a avaliação quantitativa da política de cálculo de necessidades aplicada na gestão de sistemas multicamadas, a verificação da importância da cooperação entre os elos da cadeia de distribuição para gestão do fluxo de materiais e o estudo das curvas que representam o dilema ‘nível de serviço’ versus ‘custo total da cadeia’. O modelo considera o fluxo de materiais a partir do estoque em processo do laboratório até a venda para as farmácias, que pode ser aproximada pela demanda dos medicamentos visto que os estoques das farmácias são relativamente pequenos e constantes ao longo do tempo. A modelagem de custos leva em conta o custo de estoque do laboratório e dos distribuidores, o custo de pedido dos distribuidores, o custo de transporte, o custo de entrega com atraso do laboratório e o custo de venda perdida dos distribuidores. Especificamente, são considerados cenários com e sem o compartilhamento de informações entre as empresas da cadeia. Consideram-se também cenários com e sem sazonalidade na demanda. Inicialmente, cada cenário simulado é preparado com a definição do ‘período transitório da simulação’, ‘horizonte de simulação’ e ‘número de réplicas’ necessárias. Depois disso, é feito o delineamento de experimentos para identificar quais variáveis de decisão têm efeito significativo sobre o custo total da cadeia. Finalmente, é feita uma busca da parametrização de cada um dos cenários que apresente o melhor custo total da cadeia. Os resultados da simulação mostraram que as práticas atualmente empregadas na gestão dos estoques das empresas podem ter seu desempenho melhorado com a utilização da política simulada na pesquisa. Os cenários nos quais se considerou o compartilhamento de informações tiveram desempenhos semelhantes aos sem esse compartilhamento. Dessa forma, para a política simulada, conclui-se que o valor do compartilhamento de informações foi relativamente pequeno. Nas simulações pode-se verificar a melhoria simultânea do nível de serviço e do nível de estoques da cadeia. Isso mostra que a política simulada mudou o dilema (trade-off) que interliga antagonicamente essas duas características de desempenho do sistema. / This dissertation focuses on the inventory management for multi-echelon systems. The simulation model proposes a new inventory management policy and compares it to the historical performance of a medicine supply chain. The main objectives of this research are: the quantitative analysis of the method used for the calculation of material requirements in multi-echelon systems; the verification of the importance of the cooperation between the components of the supply chain to the material flow management; and the analysis of the curves which represent the trade-off between ‘service level’ and ‘total cost’. The model takes into account the material flow from the laboratory’s ‘work in process’ up to the sales to the drugstores, which can be approximated by the demand of the final consumer, since the inventory kept by drugstores is relatively small and constant in time. The costs are calculated considering: the laboratory’s and distributors’ inventory costs, the cost of orders from the distributors, the transportation cost, the laboratory’s cost of late delivery and the distributors’ cost of lost sales. Scenarios with and without the sharing of information between the components of the supply chain were both considered. The same is true for scenarios with and without seasonality in the demand. Initially, each scenario was prepared with the definition of the ‘warm-up’ period, the simulation horizon and the amount of required replications. Secondly, the design of experiments (DOE) was done in order to determine which decision variables have influence on the supply chain total cost. Finally, each scenario was tested with many different parameters in order to find the lowest cost for the supply chain. The simulation results have showed that the procedures currently applied for the inventory management can have their performance improved by the use of the policy proposed in this research. The results for the scenarios with the sharing of information were similar to the ones for the scenarios without the sharing. For that reason, we can conclude that, for the proposed inventory management policy, the value of the sharing of information through the supply chain was relatively small. In the simulations, both the ‘service level’ and the ‘total cost’ have improved. In this manner, it can be said that the new policy has improved this trade-off.

Tradução para a língua portuguesa e validação do instrumento de reações à doação de sangue - Blood Donation Reactions Inventory / Translation for the Portuguese language and validation of the Blood Donation Reactions Inventory scale.

Braz, Ana Carolina Garcia 28 November 2013 (has links)
A escala Blood Donation Reactions Inventory (BDRI) foi originalmente proposta por Meade et al. (1996) como parte de um estudo dos preditores psicológicos de reações em doadores voluntários. É composta por 11 itens respondidos pelo doador, cada um correspondendo a uma reação ou sensação referente à doação de sangue mais recente. Na literatura, a escala BDRI é associada à probabilidade de retorno de doadores de sangue, o que sugere que o instrumento é uma ferramenta efetiva para predizer se um doador realizará novas doações. O objetivo do presente estudo é traduzir para a língua portuguesa o BDRI e estudar a confiabilidade e consistência interna desta versão traduzida, bem como sua validade de critério e de constructo. O BDRI traduzido apresentou CVI superior a 80% em todos os itens e razoável consistência interna, além de mostrar que grande parte dos doadores que apresentaram pelo menos um sintoma eram primodoadores (42%) e que mais mulheres (32%) que homens (20%) relataram algum sintoma. Concluímos que os objetivos do trabalho de traduzir para a língua portuguesa e validar o BDRI foram atingidos. Esta pesquisa traz para a língua e cultura brasileiras um instrumento útil em pesquisas na área de hemoterapia. / The Blood Donation Reactions Inventory ( BDRI ) was originally proposed by Meade et al . (1996) as part of a study of the predictors of psychological reactions volunteer donors. It consists of 11 items answered by the donor , each corresponding to a reaction or feeling related to blood donation lately. In the literature , the scale BDRI is associated with the probability of return of blood donors , suggesting that the instrument is an effective tool to predicting whether a donor will carry out further donations . The aim of this study is to translate into Portuguese languagethe BDRI and study the reliability and internal consistency of this translated version, as well as its criteria validity and construct validity. The translated BDRI showed CVI more than 80 % on all items and reasonable internal consistency and showed that most of the donors who had at least one symptom were donating blood for the first time (42%), beyond showing that women reported more symptoms (32%) than men (20%). We conclude that the objectives of the work to translate into Portuguese and validate BDRI been achieved. This research brings to the Brazilian language and culture a useful tool for research in hematology.
