ItemNo Preview AvailableAnalysis of wines offered in three-starred German restaurants with special reference to the role of the sommelier [translated title]( 2008)In ganz Deutschland existieren aktuell insgesamt 9 Restaurants, die vom Guide Michelin nach strengen Kriterien mit der Höchstwertung von drei Sternen ausgezeichnet sind. Diese Sonderstellung in der Gastronomie in Deutschland weckt ein enormes öffentliches Interesse. Das Bedürfnis von Seiten weinproduzierender Betriebe sowie des Weinhandels, ihre Produkte in das streng vom Sommelier ausgewählte Sortiment zu integrieren, und langfristig eine erfolgreiche Kooperation zu realisieren, bedarf der intensiven Auseinandersetzung mit diesem komplexen Bereich der Gastronomie. Diese Arbeit bietet grundlegende Informationen über die Angebotsgestaltung der 3-Sterne-Gastronomie in Deutschland, unter besonderer Berücksichtigung der Rolle des Sommeliers, für eventuelle Entscheidungen des Marketings von Produzent und Händler. Basis der Analyse bildeten Expertengespräche mit Sommeliers. Die protokollierten Texte der halbstandardisierten Interviews wurden anschließend mit Hilfe einer computergestützten Inhaltsanalyse qualitativ interpretiert und diskutiert. Unter anderem wurde untersucht, welche Rolle der Sommelier als Einkäufer und Verkäufer, als Absatzmittler von Wein, in dieser Art von Gastronomie spielt, welche allgemeinen Kriterien die Angebotsgestaltung beeinflussen und welche Kriterien erfüllt sein sollten. Ein ebenfalls interessanter Aspekt, der im Zuge dieser Analyse studiert wurde, ist die Wahrnehmung des Sommeliers von wesentlichen Entwicklungen und Veränderungen bezüglich der Gastronomie, des deutschen Weines, des Weinangebotes, oder auch der Einflussnahme gegenüber dem Gast. Die Arbeit informiert jene, die Wein über Feinschmeckerrestaurants vermarkten oder vermarkten wollen, über die vielfältigen Dimensionen des Weinangebotes der 3-Sterne-Gastronomie, das sehr individuelle vorgehen der Sommeliers.

ItemValidación preliminar del IIESS-R. Una nueva medida de la inteligencia emocional [Preliminary Validation of the IIESS-R. A new measurement of emotional intelligence](Federación Española de Asociaciones de Psicología, 2006)El presente trabajo reporta la revisión y validación del IIESS, inventario construido para medir la Inteligencia Emocional (Sojo y Steinkopf, 2002), basado en el modelo de Mayer, Caruso y Salovey (1999). La validación del contenido de los items se realizó con jueces expertos. El análisis factorial de la versión preliminar de 103 items, con una muestra de 109 participantes, mostró la presencia de tres factores. Considerando la gran cantidad de items redactados negativamente cargados en un mismo factor, se hicieron nuevos análisis con la misma muestra, derivando una escala de 36 items. Un análisis factorial posterior, con una muestra independiente de 292 personas, reveló que el IIESS-R está conformado por tres dimensiones: Percepción de Emociones de Otras Personas, Percepción de las Propias Emociones y Manejo Emocional. Para la validación concurrente de esta versión se emplearon cuestionarios de personalidad, con resultados acordes a lo esperado, reflejando la validez de este instrumento.

ItemPacientes oncológicos con diagnostico reciente: Valoración e intervención sobre la depresión, ansiedad y calidad de vida a través de un programa preventivo de intervención(Sociedad Venezolana de Psiquiatria, 2006)La presente investigación tiene como objetivos: 1. Medir niveles de ansiedad, depresión y calidad de vida en pacientes con diagnóstico reciente de cáncer. 2. Aplicar y valorar la efectividad de un programa de prevención psicológica secundaria, sobre los niveles de ansiedad, depresión y calidad de vida en los pacientes participantes. Método: Se trabajó con una muestra de 28 pacientes con diagnóstico reciente de cáncer, 11 pacientes no culminaron el estudio, los 17 pacientes restantes fueron divididos en forma accidental en dos grupos: experimental y contról, con edades comprendidas entre los 20 y 75 años, de ambos sexos y provenientes del Hospital Militar "Dr. Carlos Arvelo". El diseño empleado fué experimental, de tipo ensayo terapéutico controlado, pre-test y pos-test en dos grupos independientes, y a través de la ejecución de un programa de intervención secundario para obtener consecuencias en los niveles de depresión, ansiedad y calidad de vida en los pacientes del grupo experimental, y compararlos con los del grupo control, evaluados a través de la escala HAD y Karnofsky. Resultados: indican que el programa de intervención secundaria es efectivo al lograr disminuir los niveles de depresión, ansiedad y mejorar la calidad de vida en pacientes con diagnóstico reciente de cáncer. Con hallazgos estadísticamente significativos entre el pre-test y pos-test del grupo experimental, post intervención. Present investigation has three objectives. 1. To measure levels of anxiety, depression and quality of life in patients with recent diagnosis of cancer. 2. To apply and value effectivity of a secondary programme of psychological prevention, upon levels of anxiety, depression and quality of life on study subjects. Method: a sample of 28 subjects with recent diagnosis of cancer, 11 subjects did not finish the study, 17 remaining subjects were divided in an accidental fashion in one experimental group and one control group with ages between 20 and 75 years, both sexes attending the Military Hospital "Dr. Carlos Arvelo" at Caracas, Venezuela. It is an experimental study design, of the controlled therapeutic essay, pre-test and pos-test on two independent groups, by means of the execution of a secondary intervention programme in order to obtain consequences on levels of depression, anxiety and quality of life on subjects in the experimental group compared with the control group, evaluated through HAM-D and Karnofsky Quality of Life Scale.

ItemExploring trends in regionalisation(Elsevier Science, 2007)In this chapter, we revisit the empirical findings of Rugman and coauthors concerning the overwhelming home-regionalisation among the world's largest firms. Using a longitudinal research design and continuous measures of internationalisation, we observe a number of secular trends. Among other, we find that sales growth beyond the home region is faster than sales growth within the home region. We use our empirical results to critique and augment existing regionalisation theory. In particular, we raise doubts about the sharp distinction in the literature between expansion in the home region and expansion in host regions.

ItemNo Preview AvailableA genetic algorithm for the generalised transportation problem(Inderscience, 2005-07-11)The generalised transportation problem (GTP) is an extension of the linear Hitchcock transportation problem. However, it does not have the unimodularity property, which means the linear programming solution (like the simplex method) cannot guarantee to be integer. This is a major difference between the GTP and the Hitchcock transportation problem. Although some special algorithms, such as the generalised stepping-stone method, have been developed, but they are based on the linear programming model and the integer solution requirement of the GTP is relaxed. This paper proposes a genetic algorithm (GA) to solve the GTP and a numerical example is presented to show the algorithm and its efficiency. Copyright © 2005 Inderscience Enterprises Ltd.

ItemNo Preview AvailableA multi-depot travelling salesman problem and its iterative and integrated approaches(Inderscience, 2006)Resource allocation is one of the major decision problems arising in higher education. Resources This paper formulates a logistics distribution problem as the multi-depot travelling salesman problem (MDTSP). The decision makers not only have to determine the travelling sequence of the salesman for delivering finished products from a warehouse or depot to a customer, but also need to determine which depot stores which type of products so that the total travelling distance is minimised. The MDTSP is similar to the combination of the travelling salesman and quadratic assignment problems. In this paper, the two individual hard problems or models are formulated first. Then, the problems are integrated together, that is, the MDTSP. The MDTSP is constructed as both integer nonlinear and linear programming models. After formulating the models, we verify the integrated models using commercial packages, and most importantly, investigate whether an iterative approach, that is, solving the individual models repeatedly, can generate an optimal solution to the MDTSP.

ItemNo Preview AvailableAn integrated multiple criteria decision making approach for resource allocation in higher education(Inderscience, 2007)Resource allocation is one of the major decision problems arising in higher education. Resources must be allocated optimally in such a way that the performance of universities can be improved. This paper applies an integrated multiple criteria decision making approach to the resource allocation problem. In the approach, the Analytic Hierarchy Process (AHP) is first used to determine the priority or relative importance of proposed projects with respect to the goals of the universities. Then, the Goal Programming (GP) model incorporating the constraints of AHP priority, system, and resource is formulated for selecting the best set of projects without exceeding the limited available resources. The projects include 'hardware' (tangible university's infrastructures), and 'software' (intangible effects that can be beneficial to the university, its members, and its students). In this paper, two commercial packages are used: Expert Choice for determining the AHP priority ranking of the projects, and LINDO for solving the GP model
