Palestinian Non-Governmental Organisations caught between Reality and Challenges

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.

A Comparative Study on Internationalization and the Role of International Offices at Selected Middle Eastern and German Universities

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.

Optimization of the Mechanical and Optical Properties of Tunable Optical Sensor Arrays (TOSA) for a Nanospectrometer in the Visible and Near Infrared Spectral Range

Tunable Optical Sensor Arrays (TOSA) based on Fabry-Pérot (FP) filters, for high quality spectroscopic applications in the visible and near infrared spectral range are investigated within this work. The optical performance of the FP filters is improved by using ion beam sputtered niobium pentoxide (Nb2O5) and silicon dioxide (SiO2) Distributed Bragg Reflectors (DBRs) as mirrors. Due to their high refractive index contrast, only a few alternating pairs of Nb2O5 and SiO2 films can achieve DBRs with high reflectivity in a wide spectral range, while ion beam sputter deposition (IBSD) is utilized due to its ability to produce films with high optical purity. However, IBSD films are highly stressed; resulting in stress induced mirror curvature and suspension bending in the free standing filter suspensions of the MEMS (Micro-Electro-Mechanical Systems) FP filters. Stress induced mirror curvature results in filter transmission line degradation, while suspension bending results in high required filter tuning voltages. Moreover, stress induced suspension bending results in higher order mode filter operation which in turn degrades the optical resolution of the filter. Therefore, the deposition process is optimized to achieve both near zero absorption and low residual stress. High energy ion bombardment during film deposition is utilized to reduce the film density, and hence the film compressive stress. Utilizing this technique, the compressive stress of Nb2O5 is reduced by ~43%, while that for SiO2 is reduced by ~40%. Filters fabricated with stress reduced films show curvatures as low as 100 nm for 70 μm mirrors. To reduce the stress induced bending in the free standing filter suspensions, a stress optimized multi-layer suspension design is presented; with a tensile stressed metal sandwiched between two compressively stressed films. The stress in Physical Vapor Deposited (PVD) metals is therefore characterized for use as filter top-electrode and stress compensating layer. Surface micromachining is used to fabricate tunable FP filters in the visible spectral range using the above mentioned design. The upward bending of the suspensions is reduced from several micrometers to less than 100 nm and 250 nm for two different suspension layer combinations. Mechanical tuning of up to 188 nm is obtained by applying 40 V of actuation voltage. Alternatively, a filter line with transmission of 65.5%, Full Width at Half Maximum (FWHM) of 10.5 nm and a stopband of 170 nm (at an output wavelength of 594 nm) is achieved. Numerical model simulations are also performed to study the validity of the stress optimized suspension design for the near infrared spectral range, wherein membrane displacement and suspension deformation due to material residual stress is studied. Two bandpass filter designs based on quarter-wave and non-quarter-wave layers are presented as integral components of the TOSA. With a filter passband of 135 nm and a broad stopband of over 650 nm, high average filter transmission of 88% is achieved inside the passband, while maximum filter transmission of less than 1.6% outside the passband is achieved.
