META-DATA VERSIONING

Adamski, Greg 10 1900 (has links)
ITC/USA 2007 Conference Proceedings / The Forty-Third Annual International Telemetering Conference and Technical Exhibition / October 22-25, 2007 / Riviera Hotel & Convention Center, Las Vegas, Nevada / Telemetry missions spanning multiple years of tests often require access to archived configuration data for replay and analysis purposes. The needs for versioning vary from simple file-naming conventions to advanced global database versioning based on the scale and complexity of the mission. This paper focuses on a flexible approach to allow access to current and past versions of multiple test article configurations. Specifically, this paper discusses the characteristics of a versioning system for user-friendly and feature-rich solutions. It analyzes the tradeoffs of various versioning options to meet the needs of a given mission and provides a simple framework for users to identify their versioning requirements and implementation.

Relación entre orientación meta y orientación frente al error en alumnos de Posgrado de la Maestría en Comportamiento Organizacional y Recursos Humanos de una Universidad Privada

Gutierrez Torres, Juan Manuel January 2009 (has links)
La tesis aborda como problema de investigación las relaciones entre las dimensiones de la orientación meta y los tipos de orientaciones frente al error en alumnos de posgrado de la maestría en comportamiento organizacional y recursos humanos de una universidad privada. Para responder a esta interrogante se ha efectuado una investigación de tipo aplicada con método descriptivo correlacional. Para la evaluación de la orientación meta se utilizó el Cuestionario Inventario de Orientación Meta de VandeWalle y para la evaluación de la orientación frente al error se utilizó el cuestionario COFE de Rybowiak. El primero reporta para el presente estudio una confiabilidad de .62 utilizando el coeficiente de Cronbach y una validez alta mediante el coeficiente de Aiken. El segundo reporta una validez de .87 utilizando la fórmula de Kuder Richardson. La muestra de estudio estuvo constituida por el 100% de los 75 estudiantes de posgrado en la mención de Comportamiento Organizacional y Recursos Humanos. El estudio encontró que de un total de 24 relaciones entre la orientación meta y la orientación frente al error, existe relación significativa en doce de ellas. La orientación meta aprendizaje correlaciona significativamente con la orientación frente al error, la competencia frente al error, aprendiendo de los errores, tomando riesgos de errores, ocultar errores y tensión frente al error. La orientación meta desempeño correlaciona significativamente con la orientación frente al error, competencia frente al error, pensando sobre errores y aprendiendo de los errores. La orientación meta evitación correlaciona significativamente con la orientación frente al error, ocultar errores, tensión frente al error y aprendiendo de los errores.

Detecting and correcting publication bias in meta-analysis

Li, Xin 22 September 2010 (has links)
Publication bias (PB) makes the resources for meta-analysis (M-A) unreliable in the sense of completion and accuracy, so to investigate, identify and correct PB is a very important issue in M-A. The current study proposed an empirical comparison in both detection and correcting PB, using a Monte Carlo study. Conditions to be manipulated include the number of primary studies, number of missing studies and true effect size. RANNOR in SAS will be used to generate normally distributed random variables and, for each condition, 10,000 M-As will be simulated. Type I error rates are to be calculated for the conditions with no PB and powers were estimated for the conditions with PB and adequate type I error control. Finally, a demonstration of how M-A can and should be used as a part of program evaluations was given. / text

"Man måste få leva i det" : En fallstudie om meta-kommunikation i en platt organisationsstruktur

Grane, Åsa January 2015 (has links)
Internkommunikation är en konstant del i varje organisation eftersom alla människor på något sätt kommunicerar. Forskning har visat att internkommunikation på många sätt kan öka en organisationens lönsamhet, förutsatt att den är väl fungerande och inkluderar alla anställda. Tydliga instruktioner och direktiv för alla delaktiga parter är två grundförutsättningar. Dessa anvisningar och förtydliganden kallas meta-kommunikation. Mitt syfte har varit att undersöka hur sådan kommunikation hanteras i en platt organisationsstruktur utan tydliga chefspositioner, vilket leder till oklarhet gällande vem som ska ge dessa direktiv.   En instrumentell fallstudie där syftet är att granska en specifik händelse eller organisation utfördes med bostadsbolaget KBAB som undersökningsobjekt. För att kunna uppfylla syftet och svara på frågeställningarna var jag intresserad av att få ta del av de anställdas tankar och uppfattningar, vilket gjorde att den metod som lämpade sig bäst och också utfördes var personliga intervjuer.   Resultatet visar att meta-kommunikation i en platt organisationsstruktur ter sig annorlunda än i en hierarkisk. Den är inbyggd i varje anställds tjänst på så sätt att den faller på varje individs eget ansvar. Arbetssättet kräver mycket samarbete medarbetarna emellan, och aktivt deltagande i internkommunikationen är därför en förutsättning för att arbetet i organisationen ska fungera. De hinder som organisationsstrukturen visade sig skapa för meta-kommunikationen var tidsbrist, en otydlig överblick över de anställdas arbete och särskilda krav på varje individs personlighet. Ytterligare en slutsats som gick att dra av resultatet var att den platta organisationsstrukturen ur många aspekter gjorde de anställda medvetna. Det här visade sig särskilt i en medvetenhet om organisationens arbetssätt och i insikten om vilken viktig roll internkommunikationen hade i detta.

Mindfulness-based therapies for psychological health conditions : a meta-analysis

McCarney, Robert William January 2010 (has links)
Mindfulness-Based Therapies (MBT) are a current technology within the cognitive behavioural tradition, which can be grouped according to whether mindfulness is a major or a minor component. A mindful approach to psychological difficulties attempts to change the relationship with unwanted inner experience. The model suggests this may help reduce affective symptomatology. There has been a considerable growth of interest in these therapies with an accompanying increase in the evidence base. A number of reviews have been conducted however they have not comprehensively appraised these therapies. The primary aim of my study was to contribute to ongoing research determining the effectiveness of MBT for the treatment of affective symptomatology. Depending on these results, a secondary aim of the study was to make recommendations for the use of MBT in clinical practice. Methods I conducted a meta-analysis which looked separately at therapies considered to have mindfulness as a major component; therapies considered to have mindfulness as a minor component; and a comparison of these two groups. Of the 598 unique citations identified in the literature, 113 were assessed for eligibility and 40 included in the pool of studies for the meta-analysis. Results For the major component therapies, there was a significant mean reduction score in depressive symptomatology as measured by the BDI of 8.73 points (k = 11; 95% CI = 6.61, 10.86). Evidence of effectiveness was also found for the minor component therapies (k = 8) in reducing anxiety symptomatology with a significant standardised mean difference of 1.24 (95% CI = 0.81, 2.10). Discussion I found evidence for the effectiveness of mindfulness-based therapies in reducing levels of depression or anxiety mainly in patients diagnosed with depressive or anxiety disorders. The robustness of these findings is discussed alongside the implications for research and practice within the context of the current literature.
