Weiterbildung und Personalentwicklung 40plus: eine praxisorientierte Strukturanalyse

Die vorliegende Strukturanalyse „Personalentwicklung und Weiterbildung 40plus“ verfolgt (…) das Ziel, auf Anforderungen und Maßnahmen aufmerksam zu machen, die für eine altersgerechte Qualifizierung und Personalentwicklung förderlich sind und es erleichtern, älter werdende ArbeitnehmerInnen gleichberechtigt mit anderen Beschäftigtengruppen in die betriebliche Personalpolitik zu integrieren und ihre Beschäftigungsaussichten zu verbessern. Zu diesem Zweck werden nach einem einführenden Problemaufriss (Kapitel 1) zunächst die spezifischen betrieblichen Qualifizierungsrisiken, denen ältere ArbeitnehmerInnen ausgesetzt sind, dargestellt (Kapitel 2). Daran anschließend wird näher auf die vorhandenen Konzepte und Modelle zur Qualifikations- und Kompetenzentwicklung im Erwerbsverlauf eingegangen (Kapitel 3). Abschließend werden Fragestellungen formuliert, anhand derer die Umsetzung der vorgestellten Ansätze in der betrieblichen Praxis überprüft bzw. angestoßen werden kann (Kapitel 4). (DIPF/ Orig.

Engaging Middle School Students Through Music History Mini-Lessons: a Mixed-Methods Study

Understanding history is a vital part of learning. Nearly every question asked in a music classroom about musical context involves its history, from notation to gestures or technicality to aural listening. History can bring music to life for both the performers and listeners. Despite multiple studies on specific historical music events, music history perspectives have not been addressed in the choral classroom. Moreover, research forums have yet to explore engagement factors of middle school students through a music history curriculum in the choir classrooms. Such research could provide a valid model for educators. This mixed-methods research study seeks to determine if music history lessons offer a statistically significant difference in student engagement by identifying viewpoints that have not been explored and documented concerning middle school choir students’ learning, values, and understanding of music. The researcher will illustrate an engagement of middle school choir students with the musical genres of jazz, rock, pop, and classical before and after mini-lessons about the historical context. Responses were collected through a pre-test and post-test survey and questionnaire. This quasi-experiment will utilize a control and variable group of seventh-grade choir students (N=68) from a middle school in Iowa

An alternative procedure for modeling of Knudsen flow and surface diffusion

An alternative procedure for the calculation of impingement rate distribution and simultaneously the transmission probability in pores under Knudsen diffusion conditions is introduced. It is based on a combination of the finite difference method and a projection approach. Pore entrance and exit effects, and the influence of the pore length on diffusive fluxes are investigated. Later on, it is applied for a simultaneous Knudsen and surface flow system. In the model, the equation system is built without the independent flow and adsorption-desorption equilibrium assumptions. For the conditions investigated, the results indicate that if the surface flow rate is substantial, the independent flow and adsorption equilibrium assumptions become improper estimates for the behaviour of the system. The surface and gas flow rates, the impingement rate distribution and the surface coverage behave much more complex than the characteristics found with such assumptions

MONTE CARLO CALCULATIONS: DIFFUSION IN ZEOLITES

The objective of this study is to estimate the diffusivities of single and multicomponent systems as a function of temperature, concentration and parameters of the zeolite frame- work

NUMERICAL CALCULATION OF PRESSURE FIELDS IN SONOCHEMICAL REACTORS - LINEAR EFFECTS IN HOMOGENEOUS PHASE

During the last 50 years sonochemistry was under active investigation. Nevertheless, there is still a lack of a sound theoretical basis for the design of sonochemical reactors. Furthermore, sonochemical reactions are not understood in detail on a molecular level. In order to calculate the yield of chemical reactions in reactors of different shapes one needs to know the number of cavitation bubbles in the reactor. These bubbles are generated by oscillating pressures in the liquid. Therefore, as a first step of the design of sonochemical reactors pressure fields in homogeneous media in reactors of different geometric shapes are calculated .

MULTICOMPONENT DIFFUSION AND REACTION IN COMPOSITE CATALYSTS - A MONTE-CARLO AND DUSTY-GAS MODEL APPROACH APPLIED TO THE METHANOL-TO-OLEFIN SYNTHESIS IN ZEOLITES

A model of the description of reaction and mass transport within composite catalysts by Ruckenstein was improved by taking a volume change during the reaction into account, and by describing the internal fluxes by the Dusty-Gas Model. A new numerically improved notation of the Dusty-Gas-Model equations was investigated. The new model is used for describing the Methanol-To-Olefin synthesis in zeolite catalysts. The diffusivities in zeolite particles were obtained by a Monte-Carlo approach. The new model offers an improved description of experimental data

Digital scriptum – novel approach of student experiment preparation

[EN] In mechanical engineering, students pass several seminars aiming at selfconducted experiments and trials. In the ELLI project (Excellent Teaching and Learning in Engineering Science), different virtual and remote laboratories have been installed within the three engineering departments at the Ruhr-University Bochum. The preparation in a classic experiment is usually done with a classic paper print scriptum. This is not suitable for a virtual or remote laboratory, since, amongst others, no supervision is provided. Due to that, a classic scriptum has been transferred in a digital scriptum based on the Open Source software “Adapt Learning” and has been extended by various implemented digital items. This contribution is discussing preliminary student experiences and identified prospective improvements. It turns out that the digital scriptum is suitable for the preparation of virtual and remote laboratories but can be an excellent alternative to the classic printout scriptum in a student experiment in a hands on laboratory as well.http://ocs.editorial.upv.es/index.php/HEAD/HEAD18Roß, N.; Kuska, R.; Rieth, I.; Frerich, S.

Schizotypy, Alexithymia and Affect as predictors of Facial Emotion Recognition Capability using static and dynamic images

The main purpose of the present study is to investigate the capacity of schizotypy and alexithymia traits, in combination with affectivity to predict facial emotion recognition capability in a sample of nonclinical adults. Consecutive healthy participants (N= 98) were investigated using the Toronto Alexithymia Scale-20 (TAS-20), the Oxford-Liverpool Inventory of Feelings and Experiences-Reduced Version (O-LIFE-R), and the Positive and NA Schedule (PANAS). A set of validated photographs (static images) and virtual faces (dynamic images) for presenting the basic emotions was used to assess emotion recognition. Pearson correlations were applied to investigate the relationship between the study variables; the amount of variance in emotion recognition capability predicted by OLIFE-R, TAS-20 and PANAS was calculated by using the linear regression model. Results showed that alexithymia was strongly associated with schizotypy and NA; furthermore, alexithymia and NA made a significant contribution to the prediction of emotion recognition capability. The predictive model was fitted for two types of presentations (photographs and virtual reality). The inclusion of virtual faces emerges as a response to the need to consider computer characters as new assessment and treatment material for research and therapy in psychologyEl objetivo principal del presente estudio es investigar la capacidad de predicción de los rasgos de esquizotípia y alexitímia, en combinación con la afectividad, de la habilidad de reconocimiento de emociones en una muestra de adultos sanos. Noventa y ocho pacientes sanos (N =98) fueron evaluados mediante la Escala de Alexitímia Toronto-20 (TAS-20), el Inventario de Sentimientos y Experiencias Oxford-Liverpool-Versión Reducida (O-LIFE-R), y la Escala de Afecto Positivo y Negativo (PANAS). Para la evaluación de la capacidad de reconocimiento de emociones a nivel facial, se utilizó un set validado de fotografías (imágenes estáticas) y caras en realidad virtual (imágenes dinámicas). Para el análisis correlacional de las variables de estudio se aplicó la prueba de correlación de Pearson; para el análisis de predicción de la capacidad de reconocimiento emocional se utilizó un modelo de regresión lineal en el que se incluyeron las variables derivadas de las escalas OLIFE-R, TAS-20 y PANAS. Los resultados mostraron la existencia de una relación significativa entre alexitímia, esquizotípia y afecto negativo; el modelo de regresión reveló una aportación significativa de la alexitímia y el afecto negativo en la predicción de los errores cometidos en la tarea de reconocimiento facial. El modelo predictivo propuesto fue válido para ambos tipos de presentación de las emociones (fotografías y caras virtuales). La inclusión de las caras virtuales surge como respuesta a la necesidad de considerar los personajes computarizados como nuevo material de evaluación y tratamiento para la investigación y psicoterapia en psicología
