Dimensional structure of the Brief Symptom Inventory with Spanish College students.

The Brief Symptom Inventory is designed to assess symptoms of psychological disorders in adolescents and adults. The dimensional structure of the inventory, using exploratory and confirmatory factor analyses, was examined with a cross-sectional design in a Spanish sample of college students (N = 1,033, aged between 18 and 30 years old). Two hypotheses were tested: the original distribution of the items in nine factors, and the unidimensionality of the inventory. According to the results, a nine-factor structure seemed to be confirmed, although the strong intercorrelations found among the subscales indicated that these were measuring closely related constructs. The importance of cultural influences when assessing psychological symptoms and the need to develop national and sex norms for instruments that assess psychopathology, are also discussed.

CREATING A MODEL FOR INVENTORY MANAGEMENT SYSTEM

Tutkielman tarkoituksena oli mallintaa varastonhallintajärjestelmä, joka olisi sopiva case yritykselle. Tutkimus aloitettiin case yrityksen varastonhallinan nykytilan kartoituksella, jonka jälkeen tutkittiin varastonhallinnan eri osa-alueisiin. Varastonhallinnan osa-alueista käsiteltiin varastotyyppejä, motiiveja, tavoitteita, kysynnän ennustamista sekä erilaisia varastonhallinnan työkaluja. Sen lisäksi tutkittiin erilaisia varaston täydennysmalleja. Teoriaosuudessa käsiteltiin lisäksi kolmea erilaista tietojärjestelmätyyppiä: toiminnanohjausjärjestelmää, sähköisen kaupankäynnin järjestelmää sekä räätälöityä järjestelmää. Tutkimussuunnitelmassa nämä kolme järjestelmää rajattiin vaihtoehdoiksi, joista jokin valittaisiin case yrityksen varastonhallintajärjestelmäksi. Teorian ja nykytilan pohjalta tehtiin viitekehys, jossa esiteltiin varastonhallintajärjestelmän tieto- ja toiminnallisuusominaisuuksia. Nämä ominaisuudet priorisoitiin neljään eri luokkaan ominaisuuden kriittisyyden mukaan. Järjestelmävaihtoehdot arvioitiin viitekehyksen kriteerien mukaisesti, miten helposti ominaisuudet olisivat toteutettavissa eri vaihtoehdoissa. Tulokset laskettiin näiden arviointien perusteella, jonka jälkeen tulosten analysoinnissa huomattiin, että toiminnanohjausjärjestelmä sopisi parhaiten case yrityksen varastonhallintajärjestelmäksi.

Le burnout de l'élève : validation du School Burnout Inventory, identification de facteurs de risque et de protection et exploration des liens avec la consomation de substances

Syndrome de stress scolaire chronique, le bumout de l'élève ou bumout scolaire suscite un intérêt grandissant mais ses déterminants sont encore peu connus. De plus, ce phénomène est rarement étudié chez les adolescents francophones et aucune recherche n'a encore été menée en Suisse. Par conséquent, au travers de ce travail de thèse, nous proposons d'étendre la recherche sur le bumout scolaire aux adolescents de Suisse francophone et d'apporter des précisions sur ses facteurs de risque ou de protection. Pour ce faire, nous avons mené deux recherches empiriques impliquant 861 adolescents âgés de 14 à 18 ans et scolarisés en Suisse francophone. Ces adolescents ont répondu à une série d'échelles évaluant notamment le burnout scolaire, le stress scolaire, le soutien social, la consommation de substances et le parcours scolaire. Les résultats montrent tout d'abord que l'inventaire de Burnout Scolaire, version française du School Burnout lnventory, est un outil fiable et valide. Ensuite, il apparaît que le burnout scolaire touche jusqu'à 24% des adolescents de Suisse francophone et que ce dernier se caractérise par une perte d'intérêt pour l'école, une grande remise en question du sens du travail scolaire ainsi qu'un sentiment élevé d'insuffisance à l'école. Il apparaît également que le stress scolaire lié au succès et à l'avenir scolaire augmente le risque de bumout alors que le soutien des parents et des enseignants le diminue. Par ailleurs, nous mettons en évidence que l'effet du soutien social sur le burnout scolaire est médiatisé par le stress scolaire, ce qui souligne d'autant plus le rôle protecteur du soutien social. Nos résultats montrent également que les niveaux de bumout scolaire varient en fonction, d'une part de certaines caractéristiques du contexte scolaire et d'autre part en fonction de la sévérité de la consommation de substances des adolescents. Enfin, les connaissances accumulées dans ce travail et leur mise en perspective dans un modèle d'intervention précoce permettent d'insister sur le rôle de l'école et des professionnels de l'école dans la prévention du burnout scolaire. -- Syndrome of chronic school stress, pupil 's bumout or school bumout is of growing interest. However, little is known about its determinants. Moreover, this phenomenon is rarely studied in French speaking adolescents and no research has yet been conducted in Switzerland. Therefore, through this thesis, we propose to extend the research on school bumout to Swiss French speaking adolescents and to clarify its risk and protective factors. To achieve this, we conducted two empirical research involving 861 adolescents aged 14 to 18 and enrolled in the French part of Switzerland. These adolescents were asked to answer a questionnaire about school bumout, academic stress, social support, substance use and schooling. Results first show, that the French version of the School Bumout Inventory is a reliable and valid tool. lt then appears that school bumout affects up to 24% of adolescents in the French speaking part of Switzerland and that this phenomenon is characterized by a loss of interest in school, a great challenge to the sense of school work and a high sense of insufissance school. lt also appears that stress related to school success and academic future increases the risk of bumout while parents and teachers support decreases it. Moreover, we highlight that the effect of social support on school bumout is mediated by school stress, which further underscores the protective role of social support. Our results also show that school bumout levels vary depending on characteristics of the school context and on the severity of substance use of adolecents. Finally, the knowledge accumulated in this work and putting it onto perspective within early intervention model enable to insist on the role of school and school professionals in the prevention of school bumout

Classification and inventory management of abnormal demand items

The main objective of the study is to form a framework that provides tools to recognise and classify items whose demand is not smooth but varies highly on size and/or frequency. The framework will then be combined with two other classification methods in order to form a three-dimensional classification model. Forecasting and inventory control of these abnormal demand items is difficult. Therefore another object of this study is to find out which statistical forecasting method is most suitable for forecasting of abnormal demand items. The accuracy of different methods is measured by comparing the forecast to the actual demand. Moreover, the study also aims at finding proper alternatives to the inventory control of abnormal demand items. The study is quantitative and the methodology is a case study. The research methods consist of theory, numerical data, current state analysis and testing of the framework in case company. The results of the study show that the framework makes it possible to recognise and classify the abnormal demand items. It is also noticed that the inventory performance of abnormal demand items differs significantly from the performance of smoothly demanded items. This makes the recognition of abnormal demand items very important.

Los enfoques de aprendizaje en estudiantes universitarios Catalanes mediante el approaches and study skills inventory for students (ASSIST) = Learning Approaches of Catalan University Students Measured with the Approaches and Study Skills Inventory for Students (ASSIST)

The aim of this study is to measure the psychometric properties of a Catalan translation of the Approaches and Study Skills Inventory for Students (ASSIST), and to analyse the different learning styles used by university students, considering the influence of gender and type of studies. The instrument was administered to 834 students at the University of Girona. The results showed that most students interviewed had a deep approach to learning, although the analysis by gender showed that females tended to use a more strategic approach, while males used a deep approach predominantly. As to whether the type of studies influenced learning styles, a prevalence of deep approach was found among Science and Technology students, while a more strategic approach was found among Humanities and Education students

Confirmatory factor analysis of an inventory of perception of insecurity and fear of crime

This paper focuses on the study of the factorial structure of an inventory to estimate the subjective perception of insecurity and fear of crime. Made from the review of the literature on the subject and the results obtained in previous works, this factor structure shows that this attitude towards insecurity and fear of crime is identified through a number of latent factors which are schematically summarized in (a) personal safety, (b) the perception of personal and social control, (c) the presence of threatening people or situations, (d) the processes of identity and space appropriation, (e) satisfaction with the environment, and (f) the environmental and the use of space. Such factors are relevant dimensions to analyze the phenomenon. Method: A sample of 571 participants in a neighborhood of Barcelona was evaluated with the proposed inventory, which yielded data from the distributions of all the items provided. The administration was conducted by researchers specially trained for it and the results were analyzed by using standard procedures in the confirmatory factor analysis (CFA) from the hypothesized theoretical structure. The analysis was performed by decatypes according to the different response scales prepared in the inventory and their ordinal nature, and by estimating the polychoric correlation coefficients. The results show an acceptable fit of the proposed model, an appropriate behavior of the residuals and statistically significant estimates of the factor loadings. This would indicate the goodness of the proposed factor structure.

The Psychometric Properties of the French Version of the Personality Inventory for DSM-5.

In the context of the publication of DSM-5, the Personality Inventory for DSM-5 (PID-5) has been proposed as a new dimensional assessment tool for personality disorders. This instrument includes a pool of 220 items organized around 25 facets included in a five-factor second-order domain structure. The examination of the replicability of the trait structure across methods and populations is of primary importance. In view of this need, the main objective of the current study was to validate the French version of the PID-5 among French-speaking adults from a European community sample (N=2,532). In particular, the assumption of unidimensionality of the 25 facet and the five domain scales was tested, as well as the extent to which the five-factor structure of the PID-5 and the DSM-5 personality trait hierarchical structure are replicated in the current sample. The results support the assumption of unidimensionality of both the facets and the domains. Exploratory factor and hierarchical analyses replicated the five-factor structure as initially proposed in the PID-5.

Farmer-Managed Natural Regeneration Enhances Rural Livelihoods in Dryland West Africa

Declining agricultural productivity, land clearance and climate change are compounding the vulnerability of already marginal rural populations in West Africa. 'Farmer-Managed Natural Regeneration' (FMNR) is an approach to arable land restoration and reforestation that seeks to reconcile sustained food production, conservation of soils and protection of biodiversity. It involves selecting and protecting the most vigorous stems regrowing from live stumps of felled trees, pruning off all other stems, and pollarding the chosen stems to grow into straight trunks. Despite widespread enthusiasm and application of FMNR by environmental management and development projects, to date, no research has provided a measure of the aggregate livelihood impact of community adoption of FMNR. This paper places FMNR in the context of other agroforestry initiatives, then seeks to quantify the value of livelihood outcomes of FMNR. We review published and unpublished evidence about the impacts of FMNR, and present a new case study that addresses gaps in the evidence base. The case study focuses on a FMNR project in the district of Talensi in the semi-arid Upper East Region in Ghana. The case study employs a Social Return on Investment (SROI) analysis, which identifies proxy financial values for non-economic as well as economic benefits. The results demonstrate income and agricultural benefits, but also show that asset creation, increased consumption of wild resources, health improvements and psycho-social benefits created more value in FMNR-adopting households during the period of the study than increases in income and agricultural yields.

Inventory data management is defined as an accurate creation and maintenance of item master data, inventory location data and inventory balances per an inventory location. The accuracy of inventory data is dependent of many elements of the product data management like the management of changes during a component’s life-cycle and the accuracy of product configuration in enterprise resource planning systems. Cycle-counting is counting of inventory balances per an inventory location and comparing them to the system data on a daily basis. The Cycle-counting process is a way to measure the accuracy of the inventory data in a company. Through well managed cycle-counting process a company gets a lot of information of their inventory data accuracy. General inaccuracy of the inventory data can’t be fixed through only assigning resources to the cycle-counting but the change requires disciplined following of the defined processes from all parties involved in updating inventory data through a component’s life-cycle. The Processes affecting inventory data are mapped and the appropriate metrics are defined in order to achieve better manageability of the inventory data. The Life-cycles of a single component and of a product are used in evaluation of the processes.

Defining a framework model to determine total costs of managed desktops using ITIL best practices

In modern day organizations there are an increasing number of IT devices such as computers, mobile phones and printers. These devices can be located and maintained by using specialized IT management applications. Costs related to a single device accumulate from various sources and are normally categorized as direct costs like hardware costs and indirect costs such as labor costs. These costs can be saved in a configuration management database and presented to users using web based development tools such as ASP.NET. The overall costs of IT devices during their lifecycle can be ten times higher than the actual purchase price of the product and ability to define and reduce these costs can save organizations noticeable amount of money. This Master’s Thesis introduces the research field of IT management and defines a custom framework model based on Information Technology Infrastructure Library (ITIL) best practices which is designed to be implemented as part of an existing IT management application for defining and presenting IT costs.
