Islamic financial options: Design for speculation and risk management
المؤلفون: Mohammad Haniniملخص تتناول الدراسة طبيعة عقود الخيارات المالية (Options Financial) في الأسواق المالية والتجارية العالمية المنظمة، والطريقة التقليدية التي يتم تداول الأصول المالية والحقيقية بها، كما تتناول آراء الباحثين والإقتصاديين الإسلاميين حولها، وهي آراء تتلخص بعدم موافقة الخيارات في واقعها العملي مع أدبيات الإقتصاد الإسلامي، لكن بالنظر إلى وظائف هذه الخيارات وما تقدمه من منافع للدول ومؤسساتها، مثل: (الإستثمار، والمضاربة، والتحوط)، فليس في هذه الوظائف ما يخالف أدبيات الإقتصاد الإسلامي من حيث المبدأ، بل لا يستطيع النظام المالي التقليدي أو الإسلامي الإستغناء عنها، لذا هدفت الدراسة إلى معرفة مدى إمكانية إعادة هندسة هذه الخيارات وفق أدبيات الإقتصاد الإسلامي والإفادة منها، وسيتم التأكد من إمكانية تحقق ذلك بتحديد عناصر مخالفة الخيارات المالية لأحكام الشريعة الإسلامية، والتي تتمثل في: (إستخدام الخيارات من قبل المستثمرين بغرض المضاربات غير المشروعة، المتمثلة تحديداً في عنصرين، الأول: عدم التسلم والتسليم في موعد تصفية العقد، والإستعاضة عن ذلك بالتسوية النقدية، وهي المقامرة في الفقه الإسلامي، والثاني: التورط في إحدى محددات العرض والطلب المصطنعة). وعند إستثناء هذين العنصرين من عقود الخيارات، والإلتزام بالضوابط الأخرى المبينة في الدراسة، سيتم التوصل إلى تصميم خيارات مالية إسلامية جديدة، يمكن (للأفراد، والشركات، والحكومات) الإفادة منها في أسواق المال المحلية والدولية التقليدية والإسلامية، متميزة بتقديم ذات الوظائف للمستثمرين والمتحوطين المهتمين بالتداول وفق أحكام الشريعة الإسلامية. الكلمات الدالة: الخيارات المالية، الأسواق المالية، الأصول المالية والحقيقية، الإقتصاد الإسلامي، الإستثمار، المضاربة، التحوط، المقامرة، خيار الشراء، خيار البيع.

Designing productive landscapes in an emerging desert metropolis: The Case of Doha
المؤلفون: Anna Grichting SolderAs Qatar is preparing to host the FIFA World Cup in 2022 and submitting a bid for the 2024 Summer Olympic Games, the country is pushing forward with large infrastructural developments which include public and private transport, tourism and hospitality venues, as well as a number of cultural spaces and educational institution. While these will respond to the logistical and consumption needs of such Mega Events and the aspirations to develop a diversified economy, another question related to more basic consumption needs is that of Food Production and Food Security. The State of Qatar - similar to its dryland neighbors - faces limited land and water resources, and challenging soil typology restraining its agricultural production. Qatar relies on current levels of domestic agricultural output that satisfy no more than ten percent of total national food consumption needs and 99% of the water supply is provided by desalination. In the light of these extreme conditions, it is important to find new approaches to design strategies that create a symbiosis between buildings and landscape, and to explore the possibilities of creating urban food systems and edible landscapes. As a new paradigm for the Design Disciplines, the question of Food Security prompts a necessity for innovative projects that integrate food production, maximizing productivity and minimizing land use, water and energy resources. A "systems approach" to design that consumes less resources, recycles waste, and educates the consumer to have a more "nimble" footprint on the planet is the objective of new design approaches that are "regenerative" in nature. Productive urban landscapes are implementations of this regenerative approach, which promote circular rather than linear systems, and which seek to generate surplus outputs rather than zero-energy balance. The edible landscapes vary in scale and typology, from the garden lot and pocket community garden or greenhouse, to the large scale landscapes that combine food production and leisure, and vertical farming in dense cityscapes. Rooftops of shopping malls and parking infrastructures and other industrial buildings can accommodate greenhouses and greenroofs, using recycled grey water and organic waste with aquaponic systems to grow food. A series of speculative designs to propose new scenarios for Food Urbanisms in Doha and Qatar developed by students at Qatar University are presented here, and this ongoing research on new productive landscapes for Qatar is expected to contribute to the establishment of new "consumer-productive landscapes" and possibly to the development of a Food Security Master Plan being established by the Qatar National Food Security Program.

Mining flikr for museum feedback: Case study on the Qatar Islamic Museum of Art
المؤلفون: Sally Jo CunninghamMuseums are increasingly placing digital images of portions of their collections online. Weblogs of visits to these online 'digital museums' can then analysed to give the collection curators a sense of what portions of the digital collections are attracting the greatest degree of interest (as coarsely measured by 'hits' on images). Some sites support commenting by viewers, and these comments also can be useful in gaining insight into the interests of the viewers [1] and can be 'mined' to suggest additional useful metadata for the collection [2]. However, these digital museums generally include only a small fraction of the items on display in the physical museum. We propose a method for uncovering visitor interest across the entire physical museum's display, by 'mining' a public repository of personal photographs for photos taken during visits to the museum. The visitors can be assumed to take photos of those museum exhibits that has the highest personal impact on them—for example, if they find the item to be interesting, shocking, entertaining, or so forth. In this case study we examine photos of visits to the Museum of Islamic Art in Doha, as uploaded to Flickr. Specifically, we select a sample of 500 photos tagged with "Qatar Islamic Museum" (the keywords that appear to be most common for this museum). From that sample we manually categorized the images to be either photos of the museum itself, or photos of item(s) in the collection. For each of these base categories, we further downloaded and analysed the metadata applied by the photographer to the image, Comments that other Flickr users added, and the number of times that the image was Favorited by Flickr users. The photographs of collection items were further manually manually grouped and characterized by item type (eg, Ceramics, Tapestries, etc.). Where possible, multiple images of the same object were identified. These results of the manual analysis support an insight into the visitor experience to the Museum of Islamic Art. We also present a prototype of a 'control panel' for the Museum that will allow the Museum's curators to automate the process of downloading photos of the Museum and its collection, together with the Flickr metadata accessible through the Flickr API (Comments, Favorite counts, etc). This data is then displayed in an Excel spreadsheet together with the original photo, and macros support the curator in analysing the data. We argue that this system will support the curators in seeing the Museum from a visitor's point of view—to gain insights into what they enjoyed, valued, and connected with most strongly.

Effectivness of the use of ATP tournament to improve the city image by Doha and Dubai
المؤلفون: Wadih IshacBackground: Mega sports events are central stages that not only feature professional athletes representing their country in competing for excellence, but also provide host nations with a universally legitimate way to present and promote their national identities and cultures on a global scale. The members of the GCC, many of them geographically small with developing cities and physical infrastructures, have great financial resources due to their export of oil and gas. States, like the United Arab Emirates and Qatar, have been active in hosting, wanting to host, and inviting international sporting teams and institutions to hold mega sports events on their territory in an effort to raise their national profiles. Objective: Aim of the study is a comparison of the effect of hosting the ATP World Tour event by two different countries from the peninsula - Dubai and Doha. Specifically the investigation focuses on analysis of outcomes relative to input in terms of effect on the city image. The benefits from hosting these events on the image of the country are presented. Method: Improving the country image is difficult to quantify. Scoring system for media and social media are developed on which the country is mentioned in these sources. In the comparison I took several media resources to compare regionally, and internationally. A search for each host city was performed on CNN, BCC, The Official ATP tournament page, and the Middle East Newsstand database (proquest) in relation to the ATP tournament. A similar internet review was performed, specifying the time and the area (e.g. United Kingdom, United States of America, France, Spain, Serbia, and Sweden) to sample local news sources. Due to the growth of influence of the social media, coverage of the event was also analyzed in different social media outlets (Facebook, twitter, etc). Results: The results show a higher effect regionally than internationally, and international coverage was dependent on the presence of the big name players. In terms of coverage in the press and online, Dubai is more cited than Doha. Overall, Dubai is getting more benefit than Doha because its event is twice as important as Doha's tennis event in terms of ATP ranking. Conclusions: Both cities started hosting the tournament in the same year, improved ATP world ranking, which was result in more international publicity and improve its image around the World. Doha may wish to learn from Dubai example.

Visualizing life in Qatar through the lens of twitter
المؤلفون: Ingmar WeberIn this interactive poster (a set of public web demos) we present insights into the socio-cultural activity in Qatar as seen on Twitter. Our starting point is the identification of around 70,000 active Twitter users that are, either permanently or temporarily, based in Qatar. This identification is done using a number of features such as (i) the self-stated location, (ii) the geo-tagged position of tweets from geo-enabled mobile devices, and (iii) a large amount of interest (= following) in local Twitter accounts such as @dohanews (“Doha News”), or @qatarevents (“I love Qatar”). Comparing to estimates from the Arab Social Media Report compiled by the Dubai School of Government we are confident that our sample includes the majority of active Twitter users in Qatar. For this user population we regularly obtain all their public tweets using the public Twitter API and annotate them with geographic co-ordinates (if the tweets comes from a mobile device) and with the language used. Language detection is performed using state-of-the-art libraries which work well for most cases but still fail for the comparatively small number of Tweets in Arabizi or other transliterated languages. The first demo visualizes the variation in language usage in different parts of Qatar in general and Doha in specific. Whereas English dominates in West Bay, Arabic dominates in less urban areas and Tagalog, the main Philippine language, is very prominent in the Industrial Area. This simple analysis already illustrates potential applications for more systematic social science studies. The second demo visualizes the “pulse of the city” and allows the user to select a day of the week, time of the day and language of interest. Areas that are more or less active than expected are highlighted which provides insights into where people live, work or are actives on weekends. For the last demo, we manually compiled topical lists of words related to topics such as traffic, sports, shopping, religious activities and references, family and friends, and work. These lists are translated to English, Arabic and Tagalog, the main languages in our data set. The user then has the option to see areas with an increased activity either in time (e.g. mosques for religion) or in space (e.g. Aspire for sports). We believe that this exploratory, interactive study shows promising potential for large scale demographic studies as well as for survey-type analysis to get insights into the worries and concerns of large parts of the populations. Though the Twitter population is clearly not a representative sample of the offline population, a bias could potentially be corrected by weighting different members in the sample differently. For example, older users or Indian workers, two groups that are underrepresented in our current data, could be given additional weight. We hope that our interactive presentation will initiate conversations and spark new ideas on how to use Social Media for social science research.

The effects of a book-based program on literacy development of Arab children learning English as a second language
المؤلفون: Fatma Al-MaadheedStudies on effective instructional strategies for developing biliteracy skills have been limited. Investigation of child biliteracy acquisition across cultures and contexts have even a lesser share in the literature. This article reports a study which explored how a shared reading program can develop aspects of children's second language reading. The study focused on the potential gains of sharing big books and modelling reading behaviour (shared reading)and using guided reading on young second langue learners (7-10 years of age) . The areas of potential development were reading accuracy and reading comprehension of L2 texts. 36 children of Arabic L1 were divided into two groups : an experimental group and a control group. The intervention lasted for four weeks. Children in the experimental group read graded children's books with the researcher in small groups . The control group were given no intervention apart from their regular ESL classes. Statistical analysis of children's attainment at pre- and post- tests of the two measures show that the children in the experimental group developed significantly compared to the control group. Although it is acknowledged that the intervention was not compared to another instructional program; the significance of the study lays in emphasising the role of direct instruction in the teaching of L2 reading in child SLA.

Towards Measures Of Well-Being For Qatar
المؤلفون: Richard LeeteTraditionally countries looked at measuring well-being in terms of income growth. But size and growth of GDP reflects aggregate economic performance and is not necessarily a good measure of individual or national well-being ― low income groups may not always benefit ― and increasing GDP growth is unsustainable if depleting the natural resource base. International policy focus now shifting to measuring well-being of individuals and nations and quality of lives of individuals and populations. New and innovative methods to monitor well-being and happiness are being devised by international agencies, some countries, as well as NGOs and private sector. National well-being is now being understood and measured through many dimensions of people's lives, attitudes and aspirations using traditional and non-traditional data sources. The paper will provide a background on the evolving international focus on measures of well-being, including the approaches of UNDP, Stiglitz, government of the UK, Legatum Institute, OECD, BCG and Gallup/Silatech, and make the case for developing a well-being index for Qatar. It will touch on Qatar's new Social Prosperity Index and present the methodology and results of new measures of well-being for Qatar in the domains of health, education and environment

Achievement oriented beliefs and its relation to academic expectation and school achievement among Qatari students
المؤلفون: Ramzi NasserBackground: This study explored the relation between motivational goals and future goals and school academic achievement motivational activities. The premise is that motivational goals play a fundamental role in academic values and achievement. Purpose: The purpose of this study was to investigate the relationships between motivational goals and university intention, school values and school achievement. Methodology: Confirmatory factor analysis was conducted to establish the construct validity of the motivational measures drawn from the Inventory of School Motivation: Mastery (Task and Effort) Performance (Competition and Social Power) Social (Social Concern and Affiliation) and Extrinsic (Praise, and Token). A set of eight regression analyses was then carried out to examine the relationships between these eight motivational measures, future goals of University Intention, School Value and six academic subjects. Results: The eight regression equations revealed that Mastery, represented as Effort and Task were the significant and main predictors on the eight dependent variables of University Intention, School Valuing and School Achievement. Conclusion: Students in Qatar exhibited effort and task in goal motivation in relation to student beliefs of future academic goals and objective measures of achievement in all academic subjects. Students in Qatar have a strong sense values in terms of Effort.

Models of bilingual education in majority language contexts: An exploratory study of bilingual programmes in Qatari primary schools
المؤلفون: Fatma Al-MaadheedMany regions in the Middle East are currently implementing bilingual-type programmes in their national education. The abundance of initiatives in the region (e.g. Qatar, UAE, and Bahrain) suggest that this represents more than just a quantitative increase of second language provision in schools. This marks a shift from bilingual education being for the elite only towards encapsulating forms of bilingual education within public education. However, with the lack of formal documents and super-national language policies formulated to state the goals, policies and guidance for language education in the states (such as The European Commission's White Paper on Education and Training, 1995, or the Plurilingualism Promotion Plan issued by the Andalusian government in 2005) presents a caveat increased by the scarcity of research to surround these bilingual practices before and after the national changes in education and the language-in-education issues. Documenting this change is informative for the educational sector internationally especially with the interest in educational exportation in recent years. This study sought to gain an insight into the policy and practice of language-in-education in the Qatari educational system by exploring and describing the organisation and implementation of bilingual education in Qatar. It focused on the bilingual programmes offered to Qatari students and Arabic speaking children at international and independent primary schools in the unique linguistic and socio-economic context of Qatar, where Modern Standard Arabic, English and the Qatari dialect are spoken. Following a case study approach, I attempted to determine how bilingual education was conceived and carried out in international and independent schools by investigating various aspects of their bilingual and biliteracy practices. I concentrated on arrangements for the allocation, distribution, and separation of two languages (Arabic and English) with respect to fourth grade children. In addition to observing the bilingual methods and biliteracy approaches used in the classroom, and interviewing the teachers, I examined secondary data drawn from a database.The analysis of the two cases examined revealed various differences across two types of schools within a small country such as Qatar. Following a thematic approach the results are discussed within two corollaries: curricular organization and classroom praxis. Findings reveal that the international school followed a partial immersion type of bilingual education while the independent school followed a CLIL-type of bilingual education. The findings also reveal interesting results of the prominent use of IRF type of exchanges in both L1 and L2 classes. The flexible language use and purposive code-switching were discussed and documented as significant contributions to key concerns in contemporary bilingual education. As a whole the two case studies, supported by some statistical descriptions, reflected an instance of the official bilingual education context in Qatar.

The problematic decline of the humanities in today's financial markets
المؤلفون: David LeaThis paper approaches the decline in the study and teaching of the of the humanities within the university context from a financial perspective. As humanities departments are either closed down or have their curriculum attenuated, in the obvious sense we can say that the revenue that was previously present to support such programs has been not been forthcoming. Accordingly, this paper argues that resources that could have supported the humanities have been available to the university but they have been applied elsewhere. These available resources have been applied to increasing the administration and ancillary support staff, and secondly, in support of the social sciences and increasing numbers of business and management programs. This paper links this decline to the growing financialization of the economy, the ideology of managerialism and a contemporary tradition that accords with the “procedures of the public realm of the market and of liberal individualistic politics”.

From vernacular to official language: A case study of language shift in Iran
المؤلفون: Hossein RaeesiIn multilingual context of the present Iran, recent years have witnessed a significant tendency among families in indigenous communities to undermine the mother tongue and speak the official language of Persian to young children. Therefore, the present study aimed at finding out the main reasons for language shift from native to official among Dehloran families in Ilam, Iran. A questionnaire consisted of 46 items to identify the main reasons for language shift was distributed among 206 participants to reflect their views on the basis of a five-point Likert scale from Strongly Agree to Strongly Disagree. Results indicated that the majority of people related language shift to reasons such as the belief in better understanding of educational materials in school as well as achieving fluency in Persian, the role of Persian as the lingua franca of all Iranian ethnics, and the use of Persian in expanded domains. Moreover, the participants believed that the language shift is not confined to a particular social class but is pervasive among all members of the society.

Inflation management strategies for Qatar
المؤلفون: Weshah RazzakAlthough a fixed nominal exchange rate regime acts as a nominal anchor it may not achieve domestic price stability. Monetary policy cannot target the exchange rate and domestic prices at the same time they are jointly determined. To manage inflation, the exchange rate has to be floating and price stability can be achieved by either discretion or by adhering to rules. There are a number of rules such as the Taylor rule (Taylor, 1993), where the central bank responds to deviation of inflation from a specified target level, demand, and possibly the current growth rate; targeting the price level, fixing the money growth rate (Friedman, 1968), or nominal GDP targeting (McCallum, 1988). We show that any of these policies in Qatar would have resulted in stable prices but with either higher interest rate or lower rate of growth of money that otherwise observed.

Assessment of the maternal genetic diversity patterns of Chicken in Arabian Peninsula
المؤلفون: badar aliD-Loop of mitochondrial DNA (mtDNA) is widely used to investigate the chicken populations history, origin, migration or evolution. No previous genetic data is available on the chicken from the Arabian Peninsula. In this study, a 420 bp fragment of D-Loop of Mitochondrial (mtDNA) was used to estimate the genetic diversity and origins of local chickens in Arabian Peninsula (including the isle of Socotra) and Somalia. From 207 sequences (175 from the current study and 32 from GenBank), we retrieved a total of 27 haplotypes with an average haplotype diversity of 0.7588 (±0.0300). From 5 chicken populations in Oman, Saudi Arabia, Yemen, Socotra Island and Somalia, we revealed 3 distinct clades; clade E, a likely Indian subcontinent origin as the commonest clade in Oman, Saudi Arabia and Socotra Island; clade C, a Southeast Asia origin appeared mainly in Somalia and clade A, Southeast and/or East Asia origin appeared in few individuals. We attributed the wide presence of clade E to the seafaring trade and migration routes around Indian Ocean that has linked Arabian Peninsula with Indus Valley (center of origin). The results of Mantel test indicated that the relationship between chickens of clade E in India, Arabia, Northeast Africa, East Africa and Southeast Africa is subjected to Isolation by Distance. Our findings can provide other evidences to the role of Arabian Peninsula in the ancient historical maritime and terrestrial contacts between Asia and Africa, and indicated the presence of large maternal genetic diversity in the region, which could potentially support genetic improvement programs.

Adopting Literature in English Language Teaching Curriculum of EFL Students
المؤلفون: razieh baraniThis study aimed at investigating the use of poetry in Iranian EFL/ESL classrooms and its contribution to improving the proficiency of the students. Conducting a semi- experimental pre-test/post-test design, 44 Iranian undergraduate students of English language and literature of Ilam University were selected and assigned into experimental and control groups. Two samples of the Nelson English Language Test were used for the pre-tests and post-tests. The experimental group was taught how to make use of poetry in language learning, while the control group went on to study the prescribed syllabus planned at the beginning of the academic year. The findings revealed that the experimental group's proficiency improved significantly better than that of the control group. The results of the study also contribute to an understanding of the role of literature in language teaching and have implications for syllabus designers, material developers, and language teachers

Entrepreneurial Learning in a Multigenerational Family Business: Evidence from Nigeria
المؤلفون: Emeka OgidiEntrepreneurial Learning in a Multi-generational Family Business: Evidence from Nigeria Abstract Although a long-standing phenomenon, family business as an economic and social phenomenon has started to receive greater attention and focus from the academic research body, mainly due to the widespread of this type of businesses worldwide and their impact on economy. The subject of entrepreneurship has long been studied and the family business is considered to be the dominant form of organization in the world (Hoy and Sharma, 2012), there have still been calls for more research and studies that connects entrepreneurship and family systems (family and business) (Aldrich and Cli, 2003). Entrepreneurial learning is understood as how people acquire knowledge and enact new behaviours in the process of recognizing and acting on opportunities and of organizing and managing ventures (Rea & Carswell, 2000). Learning is an integral part of the entrepreneurial process in which human and social aspects hold as much importance as economic factors. Although entrepreneurship is an on-going process, the entrepreneur is considered central to the process as his/her entrepreneurial activities enable the existing/new organization to come into existence or correspond to the venture requirements. In family business, family members have to assume the role of innovator, manager, business owner, staff and so on, at various stages of the business and each role requires unique set of skills whose possession and application translate into a unique learning exercise. Accordingly, early participation in the day-to-day practice of the business develops a strong identification of family members with the business, a sense of ownership and a responsibility for the business preparing them not only to be fit to run a certain type of business but also to be able to identify and capitalize on opportunities (entrepreneurial learning). The paper draws on an empirical study of three generations in two family businesses through in-depth interviews, observations and organizational records. Six individual interviews were undertaken with non-family members and members of the family who had taken over or were working in the business. Data analysis was carried out via a qualitative data analysis software - NVivo - comparing both within-case and across-case analyses. The paper suggests that in family businesses, there is asymmetry between the participation of the three generations; and that entrepreneurial learning varies relatively in the first, second and third generations. Similarly, the founding generation participated through collaboration, expertise and communication while subsequent generations participated through apprenticeship, communication and new resources (especially human and social capital resources). Multi-generational entrepreneurial learning in family systems depended on the ability to replicate and transform practice, and this plays an important role in the generative capacity of a family business. We anticipate that our findings will add credence to theory (better understanding of entrepreneurial learning in a developing country), practice (useful information for family business owners) and education (development and enhancement of the curriculum on family business).

The Economics of Vertical Farming: exploring the feasibility
المؤلفون: Yiming ShaoToday, over 800 million hectares of land is committed to soil-based agriculture in order to support the World's population. Significantly, it is predicted that the World's population will rise to at least 8.6 billion within the next 50 years. This, together with the implications of climate change will inevitably lead to challenges in terms of food shortages if we continue to rely on conventional agricultural methods. As such, vertical farming may provide one of the most promising advanced options for meeting food demands in terms of quantity and quality through an urban farming solution. This is particularly the case in countries with very large urban populations, limited agricultural land, prone to natural disasters, or unable to meet their own food requirements. Vertical farming typically involves hydroponically or aeroponically growing plants in an artificially controlled environment in multi-layers on each floor within multi-storey or even high-rise buildings. The concept of vertical farming has been drawing unprecedented attention from academia to business communities for the past decade. However, despite a number of obvious advantages it has yet to progress beyond conceptual stage except a few experimental small scale examples existing in developed countries. The largest barrier to the promotion and realization of vertical farming is not the availability of technology or the ability to design and construct such a structure but the uncertainty of its economic feasibility. As such, can investors and developers make an acceptable profit and can the consumer afford the price of the produce? Although a few architects, engineers and economists have attempted financial calculations based on capital budget or operating cost, they have tended to be crude and based on certain particular circumstances or case-by-case study. This has resulted in significant limitations particularly the fact that these attempts cannot be transplanted to other cases or places. These different calculation methods are presented and analysed in this paper. More importantly, the design of vertical farms can be various, but it needs a 'benchmark' to provide more realistic economic costing. For any potential investor or developer, it may be preferable that a more accurate budget estimation is obtained at the very beginning to inform decision-making. However, the dilemma is, without detailed design drawings, the estimation is likely to be inaccurate, beyond a specific tolerance. Indeed, because the vertical farm is a relatively new building typology, without much statistical data there is no current 'cost model' for reference. Based on an elemental cost plan method, this paper proposes a modeling method for vertical farm cost estimation. The paper will outline and analyse various variables that may circumstantially influence the total budget of a vertical farm in different phases (design, construction and operation). Methodological considerations are also illustrated in terms of data resource, model validation, model transferability (re-usability of integrated modeling approaches to other research contexts) and linking of model components. Keywords: vertical farming; economic consideration; cost estimation; modelling methodology; design benchmark.

German University-based Science: From Model to Contemporary Reality?
المؤلفون: Jennifer DusdalThis QNRF-funded project features a cross-national investigation of the influence of higher education development and science capacity-building on scientific knowledge production. Measuring science on the basis of published papers in selected STEM disciplines, we identify factors behind national differences and global similarities. How does variation in national models and strategies to develop higher education and research universities explain long-term cross-national trajectories in science productivity over the 20th century? Observing unprecedented growth in scientific knowledge productivity, we selected six national cases that represent three phases of higher education development and science-based societies: a major European precursor model (Germany), American broad institutionalization of the currently dominant model, and, finally, Asian (Japan, China, Taiwan) and Middle Eastern (Qatar) innovators seeking to learn from the best. The enormous potential of a knowledge economy and society depends on continued production of scientific knowledge, but also its specification and enhanced quality. Even though scientists globally add to the world's store of scientific knowledge, there are significant cross-national differences in relative contribution. While global production grows substantially, a few nations still produce the overwhelming majority of new science. For example, the U.S. leads the world in research, producing 21% of all research papers (2004-2008). Together with China (10%), UK (7%), Japan (6%) and Germany (6%), these five countries contribute 60% of all publications globally (UKRS 2011). Our preliminary research suggests that differences in key aspects of institutional models of higher education development and science capacity-building are associated with cross-national differences in scientific knowledge production over time. We use mixed methods to analyze the institutional model of higher education development and science capacity-building in these nations over time. Our main measure is the number of published papers in journals, relying on a unique dataset from Thomson Reuters' Web of Science (1900-2011). Examining trends in journal publications in selected STEM disciplines, we analyze how universities, investments in higher education and science, international collaborations, and scientific networks have changed to create the conditions for the "knowledge society". Mainly, this poster presentation explains the influential German institutional model of the research university, which enjoyed preeminent status in modern science's early institutionalization. Placing primacy on autonomous science and valorizing the unity of teaching and research, this type of university continues to dominate German higher education. Yet massive tertiary educational expansion, the rise of extra-university research institutes, and establishment of praxis-oriented universities of applied sciences challenge the foundational principle, threaten this globally popular model, and reduce university-based research capacity in Germany. Nevertheless, Germany's dual pillars of mass universities and prestigious independent research institutes continue to boast one of the largest national scientific outputs globally. With an annual R&D investment of 2.84% GDP (2011), Germany has among the highest levels of science investment in Europe. Measured in publications, Germany still competes at the very top. While still a model for other countries, other top science countries today rely on their universities more in producing competitive science than does Germany.

Home-Based Business: A Growing Phenomenon
المؤلفون: Maryam Al-Subaie, Maryam Al-Thani and Abdulrahman Al-MuftahDuring the last five years there has been an upsurge in the number of home-based businesses in Qatar. This research investigates the reasons behind the sudden surge in home businesses, the support they receive from organizations such as Bedaya, Social Development Center and Roda Center as well as the future of home-based businesses in Qatar. Many young entrepreneurs in the country have noticed an absence in the market for businesses that sell desserts (cupcakes more specifically), fashion accessories and abayas. Creating a home-based business was one way of seizing this opportunity and meeting the market demand, at minimal start-up costs and reduced risk. Interviews were conducted with three centers that provide career and entrepreneurship guidance as well as seven home-based businesses that have been operating for at least a year. The research showed that Bedaya, Social Development and Roda Centers played predominant roles in the rise of popularity in this type of business. The advancements in social media have also made it very easy for aspiring entrepreneurs to reach out to customers at relatively low costs. The growth of home-based businesses in Qatar is an undocumented phenomenon. The study increases the awareness of home-based business in the country and is a research platform for further investigation in the field.

Qatari Colloquial Arabic Quickly Changes Over Time
المؤلفون: Maryam Al-SubaieLanguages are passed down through generations from parents to children by communication. Yet linguists find that languages (and varieties of languages) change over time - but at different rates. This study mainly aims at investigating semantic and word changes that took place in the Qatari colloquial Arabic over a period of thirty years. The research began by interviewing forty Qatari locals. The participants came from two age groups: (18-24 years) and (55-61 years) - this is to document change over time. The interview examined the presence of semantic changes in the Qatari colloquial Arabic. The linguistic variable in this study was a list of forty-five dialectical terms and expressions that were commonly used by adults 30 years ago. The second part of the research method included investigating the origin of each term from Kitab al-'Ayn (the first dictionary of the Arabic language) and Lisan Al Arab to confirm that they come from Arabic. The results of the research vary. The majority of the lexical items under investigation presented some form of change over the two generations; they showed phonetic, semantic as well as other types of change. There was also evidence of terms that were borrowed from languages such as Farsi, English and Urdo and incorporated into the Qatari local dialect, after undergoing phonetic change. Languages change for a variety of reasons. History reveals many examples of dialect change fuelled by migration/movement, colonization and economic growth. One finding of this research is that the vocabulary an individual uses nowadays is a social marker of age. An example of this includes the word ?????? )?ambalou?), meaning ambulance. This lexical item was borrowed from English before going through a phonological change, and users of this term tend to be from an older generation. The changes happening to the Qatari colloquial Arabic is an undocumented phenomenon. The study increases the awareness about the development of the language in the country and is a research platform for further investigation in the field.

Volatility Spillover Between Oil And Agricultural Commodity Markets
المؤلفون: Alanoud Al-MaadidGlobally, instability in the energy market is quickly reflected in the food market. Therefore, there exists a direct relationship between oil and food. This study adopts variance in causality tests on daily data from 01 January 1986 to 7 June 2012 in order to identify the causality of the food price crisis. The data is divided into three sub-periods: the pre-crisis period (01 January 1986 to 31 December 2005), the crisis period (01 January 2006-31 December 2008) and the post crises period (01 January 2009 - 7 June 2012). See figure1 The first part of the causality in variance analysis adopts the newly developed Hafner and Herwartz (2006) approach. It uses both univariate GARCH and the multivariate GARCH-BEKK model introduced by Engle and Kroner (1995) to analyse volatility spillover effects of the food crisis on the selected agricultural commodity markets (wheat, corn, soybeans, and sugar). In the multivariate analysis volatility spillovers have been taken into account by including a dummy variable in the conditional variance specification. The results show that the persistence of the volatility doesn't change significantly during and following the food price crisis. The second part of the causality in variance analysis uses a Granger test to determine whether the oil market influences the agriculture market, or vice versa. The test results show that while there is no risk of transmission between oil and the selected agricultural commodity markets (wheat, corn, soybeans, and sugar) in the pre-crisis period, during the crises the agriculture market's volatility - with the exception of wheat - spills into the oil market. After the crises, only the soybean market spills over to the oil market, while there is no effect in the other markets. This paper aims to foster an awareness and understanding of national food security issues. This understanding builds a knowledge-based society and helps policymakers make strategic plans that can be tailored to the unique challenges and resources of the region. It promotes innovation, discovery and economic diversification by using the newly developed multivariate garch model thereby showing that the dynamics of volatility transmission change significantly before, during, and after a food price crisis. During the crisis, risk transmission emerged as another dimension of the dynamic interrelationships between energy and agricultural markets.
