Internationalization of higher education has become one of the most important policies for institutions of higher education worldwide. Though universities are international by nature, the need for intensified quality activities of international nature has promoted internationalization to be under spotlight of researchers, administrators and policy makers and to be an area for research. Each institution follows its certain way to govern its international affairs. Most Universities, especially in the 'Developed World' started to plan it strategically. This study explores the meanings and importance of internationalization especially that it means different things to different people. It also studies the rationales behind internationalizing higher education. It focuses on the four main prevailing rationales; political, cultural/social, economic/financial, and academic on both national and institutional levels. With the increasing need to strategically plan, the study explores internationalization strategies in terms of how to develop them, what are their approaches and types, and their components and dimensions. Damascus University has witnessed an overwhelming development of its international relations and activities. Therefore, it started to face a problem of how to deal with this increasing load especially that its International Office is the only unit that deals with the international issues. In order to study the internationalization phenomenon at Damascus University, the 2WH approach, which asks the what, why, and how questions, is used and in order to define the International Office's role in the internationalization process of the University, it studies it and the international offices of Kassel University, and Humboldt University in Germany, The University of Jordan, and Al Baath University in Syria using the 'SOCIAL' approach that studies and analyses the situation, organization, challenges, involvement, ambitions, and limitations of these offices. The internationalization process at the above-mentioned Universities is studied and compared in terms of its meaning, rationales for both the institution and its academic staff, challenges and strategic planning. Then a comparison is made among the international offices of the Universities to identify their approaches, what led to their success and what led to their failure in their practices. The aim is to provide Damascus University and its International Office with some good practices and, depending on the experiences of the professionals of the case-studies, a suggested guidance to the work of this Office and the University in general is given. The study uses the interviews with the different officials and stakeholders of the case-studies as the main method of collecting the information in addition to site visits, studying their official documents and their websites. The study belongs to qualitative research that has an action dimension in it since the recommendations will be applied in the International Office. The study concludes with few learned lessons for Damascus University and its International Office depending on the comparison that was done according to a set of dimensions. Finally a reflection on the relationship between internationalization of higher education and politics, the impact of politics on Middle Eastern Universities, and institutional internationalization strategies are presented.

Nach 35 Jahren Entwicklungszeit wurde im Jahr 2004 in Shanghai die erste kommerzielle Anwendung des innovativen Magnetbahnsystems Transrapid in Betrieb genommen; in Deutschland konnte bislang keine Transrapid-Strecke realisiert werden, obwohl dieses System entsprechend den Ergebnissen einer vom damaligen Bundesverkehrsminister beauftragten Studie aus dem Jahr 1972 für den Einsatz in Deutschland entwickelt wurde. Beim Transrapid handelt es sich um eine echte Produkt-Innovation im Bahnverkehr und nicht um eine Weiterentwicklung oder Optimierung wie beim ICE, und ist somit als innovativer Verkehrsträger der Zukunft in die langfristige Entwicklung der Verkehrssysteme einzufügen. Die modernen HGV Bahnsysteme (Shinkansen/TGV/ICE) hingegen sind, ähnlich der Clipper in der Phase der Segelschifffahrt im Übergang zum Dampfschiff, letzte Abwehrentwicklungen eines am Zenit angekommenen Schienen-Verkehrssystems. Die Einführung von Innovationen in einen geschlossenen Markt stellt sich als schwierig dar, da sie zu einem Bruch innerhalb eines etablierten Systems führen. Somit wird in der vorliegenden Arbeit im ersten Teil der Themenkomplex Innovation und die Einordnung der Magnet-Schwebe-Technologie in diese langfristig strukturierten Abläufe untersucht und dargestellt. Das Transrapid-Projekt ist demzufolge in eine zeitstrukturelle Zyklizität einzuordnen, die dafür spricht, die Realisierung des Gesamtprojektes in eine Zeitspanne von 20 bis 30 Jahre zu verlagern. Im zweiten Teil wird auf der Basis einer regionalstrukturellen Analyse der Bundesrepublik Deutschland ein mögliches Transrapidnetz entworfen und die in diesem Netz möglichen Reisezeiten simuliert. Weiterhin werden die Veränderungen in den Erreichbarkeiten der einzelnen Regionen aufgrund ihrer Erschließung durch das Transrapidnetz simuliert und grafisch dargestellt. Die vorliegende Analyse der zeitlichen Feinstruktur eines perspektiven Transrapidnetzes ist ein modellhafter Orientierungsrahmen für die Objektivierung von Zeitvorteilen einer abgestimmten Infrastruktur im Vergleich zu real möglichen Reisezeiten innerhalb Deutschlands mit den gegebenen Verkehrsträgern Schiene, Straße, Luft. So würde der Einsatz des Transrapid auf einem entsprechenden eigenständigen Netz die dezentrale Konzentration von Agglomerationen in Deutschland fördern und im Durchschnitt annähernd 1 h kürzere Reisezeiten als mit den aktuellen Verkehrsträgern ermöglichen. Zusätzlich wird noch ein Ausblick über mögliche Realisierungsschritte eines Gesamtnetzes gegeben und die aufgetretenen Schwierigkeiten bei der Einführung des innovativen Verkehrssystems Transrapid dargestellt.

Non-governmental Organisations (NGOs) have not only gained more and more relevance in the development process of Near Eastern developing societies, but they have also raised an increasing scholarly interest. The traditional civil society in the Middle East, which used to be in charge of the tribe or large families, has been altered by new groups, which are organized around new social structures, interests and goals. The number of NGOs has experienced a swift increase in number and size, and the extent of some renders them important players in the social welfare sector, both at the national and global levels. The expansion and the increasing role of NGOs worldwide since the end of the 1970s as actors in socio-economic development and in the formulation of public policies has had great influence around the globe. However, this new function is not automatically the outcome of independent activity; but rather the result of ramified relationships between the national and international environment.

Summary - Cooking banana is one of the most important crops in Uganda; it is a staple food and source of household income in rural areas. The most common cooking banana is locally called matooke, a Musa sp triploid acuminate genome group (AAA-EAHB). It is perishable and traded in fresh form leading to very high postharvest losses (22-45%). This is attributed to: non-uniform level of harvest maturity, poor handling, bulk transportation and lack of value addition/processing technologies, which are currently the main challenges for trade and export, and diversified utilization of matooke. Drying is one of the oldest technologies employed in processing of agricultural produce. A lot of research has been carried out on drying of fruits and vegetables, but little information is available on matooke. Drying of matooke and milling it to flour extends its shelf-life is an important means to overcome the above challenges. Raw matooke flour is a generic flour developed to improve shelf stability of the fruit and to find alternative uses. It is rich in starch (80 - 85%db) and subsequently has a high potential as a calorie resource base. It possesses good properties for both food and non-food industrial use. Some effort has been done to commercialize the processing of matooke but there is still limited information on its processing into flour. It was imperative to carry out an in-depth study to bridge the following gaps: lack of accurate information on the maturity window within which matooke for processing into flour can be harvested leading to non-uniform quality of matooke flour; there is no information on moisture sorption isotherm for matooke from which the minimum equilibrium moisture content in relation to temperature and relative humidity is obtainable, below which the dry matooke would be microbiologically shelf-stable; and lack of information on drying behavior of matooke and standardized processing parameters for matooke in relation to physicochemical properties of the flour. The main objective of the study was to establish the optimum harvest maturity window and optimize the processing parameters for obtaining standardized microbiologically shelf-stable matooke flour with good starch quality attributes. This research was designed to: i) establish the optimum maturity harvest window within which matooke can be harvested to produce a consistent quality of matooke flour, ii) establish the sorption isotherms for matooke, iii) establish the effect of process parameters on drying characteristics of matooke, iv) optimize the drying process parameters for matooke, v) validate the models of maturity and optimum process parameters and vi) standardize process parameters for commercial processing of matooke. Samples were obtained from a banana plantation at Presidential Initiative on Banana Industrial Development (PIBID), Technology Business Incubation Center (TBI) at Nyaruzunga – Bushenyi in Western Uganda. A completely randomized design (CRD) was employed in selecting the banana stools from which samples for the experiments were picked. The cultivar Mbwazirume which is soft cooking and commonly grown in Bushenyi was selected for the study. The static gravitation method recommended by COST 90 Project (Wolf et al., 1985), was used for determination of moisture sorption isotherms. A research dryer developed for this research. All experiments were carried out in laboratories at TBI. The physiological maturity of matooke cv. mbwazirume at Bushenyi is 21 weeks. The optimum harvest maturity window for commercial processing of matooke flour (Raw Tooke Flour - RTF) at Bushenyi is between 15-21 weeks. The finger weight model is recommended for farmers to estimate harvest maturity for matooke and the combined model of finger weight and pulp peel ratio is recommended for commercial processors. Matooke isotherms exhibited type II curve behavior which is characteristic of foodstuffs. The GAB model best described all the adsorption and desorption moisture isotherms. For commercial processing of matooke, in order to obtain a microbiologically shelf-stable dry product. It is recommended to dry it to moisture content below or equal to 10% (wb). The hysteresis phenomenon was exhibited by the moisture sorption isotherms for matooke. The isoteric heat of sorption for both adsorptions and desorption isotherms increased with decreased moisture content. The total isosteric heat of sorption for matooke: adsorption isotherm ranged from 4,586 – 2,386 kJ/kg and desorption isotherm from 18,194– 2,391 kJ/kg for equilibrium moisture content from 0.3 – 0.01 (db) respectively. The minimum energy required for drying matooke from 80 – 10% (wb) is 8,124 kJ/kg of water removed. Implying that the minimum energy required for drying of 1 kg of fresh matooke from 80 - 10% (wb) is 5,793 kJ. The drying of matooke takes place in three steps: the warm-up and the two falling rate periods. The drying rate constant for all processing parameters ranged from 5,793 kJ and effective diffusivity ranged from 1.5E-10 - 8.27E-10 m2/s. The activation energy (Ea) for matooke was 16.3kJ/mol (1,605 kJ/kg). Comparing the activation energy (Ea) with the net isosteric heat of sorption for desorption isotherm (qst) (1,297.62) at 0.1 (kg water/kg dry matter), indicated that Ea was higher than qst suggesting that moisture molecules travel in liquid form in matooke slices. The total color difference (ΔE*) between the fresh and dry samples, was lowest for effect of thickness of 7 mm, followed by air velocity of 6 m/s, and then drying air temperature at 70˚C. The drying system controlled by set surface product temperature, reduced the drying time by 50% compared to that of a drying system controlled by set air drying temperature. The processing parameters did not have a significant effect on physicochemical and quality attributes, suggesting that any drying air temperature can be used in the initial stages of drying as long as the product temperature does not exceed gelatinization temperature of matooke (72˚C). The optimum processing parameters for single-layer drying of matooke are: thickness = 3 mm, air temperatures 70˚C, dew point temperature 18˚C and air velocity 6 m/s overflow mode. From practical point of view it is recommended that for commercial processing of matooke, to employ multi-layer drying of loading capacity equal or less than 7 kg/m², thickness 3 mm, air temperatures 70˚C, dew point temperature 18˚C and air velocity 6 m/s overflow mode.
