台灣省國民中學教師流動因素與型態之研究

蕭霖, Hsiao Lin Unknown Date (has links)
本研究的目的在暸解教師流動的型態與調動的因素,從83學年度臺灣省國民中學調動教師中抽取384人,並同時抽取380位未調動教師作為參照。   本研究採用虛擬依變項的迴歸分析,探討導致教師調動的因素。結果發現教師調動的型態存在往都會地區流動的現象。調動與非調動教師的比較中,在性別、教學年資、婚姻狀況與配偶的勞動參與率、自用住宅的擁有、調動次數、學校規模、以及是否為居民的變項上有顯著的不同。   在調動機率的影響方面,性別、教學年資、婚姻狀況與配偶的勞動參與率、調動次數、學校規模、以及薪資與福利措施的滿意度上,有著顯著的預測力。研究的結論是教育人力資源分配仍不平均,從影響教師調動機率的因素中,可以提供導引教育人力資源分配更加均衡的線索。 / The main purpose of this study is to inquire into the style about the teachers' mobility and the factors affecting such mobility. Sampling from 1994 academic year in Taiwan, the researcher focuses on the 384 cases of all mobilized teachers and their counterpart-380 nonmobilized cases.   A dummy dependent regression analysis is conducted to explore the factors. As a result, the phenomenon for mobility tends to flow into the metropolis. Factors affecting the mobility exhibits significant differences compared to nonmobility; such as factors among sex, seniority, marriage, inhibition, frequcncy of mobility and the scale of the school.   In additions, the propensity to mobile, as this study finds, has to do with their sex, seniority, marriage and the labor participation of spouse, frequcency of mobility, degree of the content about their wages and welfare, and the scale of the school. The conclusions made here are: the human resources in education is still scanty. From the factors influenced mobility probability, it can provide some clues to make the human resources in education more equal.

Elförbrukningen i svenska hushåll : En analys inom projektet ”Förbättrad energistatistik i bebyggelsen” för Energimyndigheten / Electricity consumption in Swedish households : An analysis in the project “Improved energy statistics for settlements” for the Swedish Energy Agency

Nilsson, Josefine, Xie, Jing January 2012 (has links)
Energimyndigheten har drivit ett projekt kallat ”Förbättrad energistatistik i bebyggelsen” för att få mer kunskap om energianvändningen i byggnader.  Denna rapport fokuserar på ”Mätning av hushållsel på apparatnivå” som var ett delprojekt. Diverse regressionsmodeller används i denna rapport för att undersöka sambandet mellan elanvändningen och de olika förklarande variablerna, som exempelvis hushållens bakgrundsvariabler, hushållstyp och geografiska läge, elförbrukningen av olika elapparater samt antalet elapparater. Datamaterialet innefattar 389 hushåll där de flesta är spridda runt om i Mälardalen. Ett fåtal mätningar gjordes på hushåll i Kiruna och Malmö. Slutsatsen vi kan dra från denna uppsats är att hushållens bakgrund, hustyp, geografiska läge och antal elapparater samt dessa apparaters typ har relevans för elförbrukningen i ett hushåll. / The Swedish Energy Agency conducted a project which is called “Improved energy statistics for settlements”. This report focuses on one field of the project: “households’ electricity use on device level”. Various regression models are used in the analysis to analyze the relationship between electricity usage and different explanatory variables, for instance: background variables for the household, type of household, geographical setting, usage of different electrical devices and quantity of electrical devices used.  The data material consists of 389 households which are spread around the region of Märlardalen except for a few households from the communities of Kiruna and Malmö. The conclusion we can draw from this thesis shows that the background variables for a household, its type, its geographical setting and the amount and type of devices it contains all have a contribution to the electricity usage in the household. / Förbättrad energistatistik i bebyggelsen

Influence of retraint systems during an automobile crash : prediction of injuries for frontal impact sled tests based on biomechanical data mining / Infkuence des systèmes de retenue lors d'un accident automobile : Prédiction des blessures de l'occupant lors d'essais catapultés frontaux basées sur le data mining

Cridelich, Carine caroline 17 December 2015 (has links)
La sécurité automobile est l’une des principales considérations lors de l’achat d’un véhicule. Avant d’ être commercialisée, une voiture doit répondre aux normes de sécurité du pays, ce qui conduit au développement de systèmes de retenue tels que les airbags et ceintures de sécurité. De plus, des ratings comme EURO NCAP et US NCAP permettent d’évaluer de manière indépendante la sécurité de la voiture. Des essais catapultes sont entre autres effectués pour confirmer le niveau de protection du véhicule et les résultats sont généralement basés sur des valeurs de référence des dommages corporels dérivés de paramètres physiques mesurés dans les mannequins.Cette thèse doctorale présente une approche pour le traitement des données d’entrée (c’est-à-dire des paramètres des systèmes de retenue définis par des experts) suivie d’une classification des essais catapultes frontaux selon ces mêmes paramètres. L’étude est uniquement basée sur les données du passager, les données collectées pour le conducteur n’ étant pas assez complètes pour produire des résultats satisfaisants. L’objectif principal est de créer un modèle qui définit l’influence des paramètres d’entrées sur la sévérité des dommages et qui aide les ingénieurs à avoir un ordre de grandeur des résultats des essais catapultes selon la législation ou le rating choisi. Les valeurs biomécaniques du mannequin (outputs du modèle) ont été regroupées en clusters dans le but de définir des niveaux de dommages corporels. Le modèle ainsi que les différents algorithmes ont été implémentés dans un programme pour une meilleur utilisation quotidienne. / Safety is one of the most important considerations when buying a new car. The car has to achievecrash tests defined by the legislation before being selling in a country, what drives to the developmentof safety systems such as airbags and seat belts. Additionally, ratings like EURO NCAP and US NCAPenable to provide an independent evaluation of the car safety. Frontal sled tests are thus carried outto confirm the protection level of the vehicle and the results are mainly based on injury assessmentreference values derived from physical parameters measured in dummies.This doctoral thesis presents an approach for the treatment of the input data (i.e. parameters ofthe restraint systems defined by experts) followed by a classification of frontal sled tests accordingto those parameters. The study is only based on data from the passenger side, the collected datafor the driver were not enough completed to produce satisfying results. The main objective is tocreate a model that evaluates the input parameters’ influence on the injury severity and helps theengineers having a prediction of the sled tests results according to the chosen legislation or rating.The dummy biomechanical values (outputs of the model) have been regrouped into clusters in orderto define injuries groups. The model and various algorithms have been implemented in a GraphicalUser Interface for a better practical daily use.

Kritische Reflexion zu verschiedenen Datenquellen zu altersbedingten Veränderungen der Beweglichkeit

Spitzhirn, Michael, Bullinger, Angelika C. 04 April 2018 (has links)
Leitthema ARBEIT(S).WISSEN.SCHAF(F)T ; Grundlage für Management & Kompetenzentwicklung Mit zunehmendem Alter kommt es zu einer Verringerung der Beweglichkeit. Mit Hilfe digitaler Menschmodelle können daraus resultierende Auswirkungen auf die Arbeitsgestaltung analysiert und bei der Planung von Arbeitssystemen berücksichtigt werden. Als Voraussetzung dafür müssen in Menschmodellen valide Daten integriert werden. Hierzu werden im Beitrag Datenquellen zur Beweglichkeit in Bezug zur altersbedingten Veränderung vorgestellt und deren Nutzung zur Ableitung von Referenzdaten für eine Integration in digitale Menschmodelle diskutiert. Als Quellen können Fachbücher, Primärstudien, Reviews und Meta-Analysen verwendet werden. Diese sind anhand von Kriterien zur Qualität und der Aufstellung von Referenzwerten zu bewerten. Im Ergebnis wird festgestellt, dass es wesentliche Unterschiede in der Studien- und Berichtsqualität gibt. Insbesondere fehlende Angaben zur Erhebung und der Studienpopulation erschweren die Studienbewertung und Einordnung hinsichtlich Referenzwerte. Referenzdaten unterscheiden sich auch hinsichtlich der Bereitstellung von alters- und geschlechtsspezifischen Angaben. Um eine adäquate Integration in digitale Menschmodelle vornehmen zu können, muss eine kritische Auseinandersetzung mit der Qualität der Erhebung und Repräsentativität der Daten erfolgen.

Vliv atrapy na chování samců strnada obecného a budníčka menšího v playbackových experimentech / Effect of a dummy on behaviour of Yellowhammer and Chiffchaff males in playback experiments

Kubátová, Hana January 2021 (has links)
A playback experiment in which a recording of vocalization is played to the tested subject and its response is observed, is a widely used tool for examining bird song and its functions. Most often only acoustic stimulus is used, but sometimes a visual stimulus is also provided in the form of a dummy. Taxidermic mounts or models made from different materials are used as the dummy. It is discussed among researchers, whether it is or is not necessary to use a dummy in experiments and how does its presence affect behavior of the tested individuals. However, only few studies directly focus on this issue and test the effect of dummies. The best way to test the effects of a dummy on passerines in playback experiments is to test the same individuals in both situations (with a dummy and without a dummy) and compare the reactions. The aim of this theses was to perform such experiments on Chiffchaff (Phylloscopus collybita) and Yellowhammer (Emberiza citrinella) males and to find out whether they would behave similarly in both variants of the experiment, or if their reaction would be enhanced in the presence of a dummy. Chiffchaffs reacted significantly more aggressively in the dummy experiment. The biggest difference was time spent by attacking the dummy and staying close to it. In Yellowhammers, the dummy...
