Higher education institutions in the Arab states : a study of objectives and their achievementHalwachi, Abdul Jalil Hassan January 1985 (has links)
Over the last two decades more attention has been paid by the governments of developed and developing countries to the role of higher education in general and universities in particular. Their major concern is the growing demand for higher education and the growing expenditure of that sector. These two reasons led to an inquiry into the role of higher education institutions, their objectives and their effective use of the resources allocated to them. The need to achieve better understanding and definition of the role of higher education institutions and effectiveness requires better understanding of the institutional objectives and their measure of achievement by the various constituencies involved in the institutions' activities. This study aimed to investigate the different objectives and to examine the appropriateness and degree of achievement of measures of a set of institutional goals in four Arab Universities. The study approach used included a literature survey of studies conducted on higher education institutions in Europe, North America and the Arab States and the collection of data by a questionnaire. The population sample represents administrators and faculty members in the four Arab Universities. Mean scores were used to generate the ranking of the objective areas, in terms of their perceived preferences among the four universities and among the respondent groups. Also, the analysis of variance technique was used to ascertain which of the objective areas and their measures received divergent views among the four universities and among the respondent groups. The analysis of variance technique was followed by Duncan's New Multiple Comparison test to identify pairs of factors which differ significantly, to help in the interpretation of the findings. The study revealed that there were differences in respondent ratings of the objective areas, their measures and degree of achievement among the four universities but not among the different respondents categories. The findings of the study provided the conclusion that: only in some objective areas were priorities perceived differently by the universities and by respondent groups; homogeneity exists among the respondent groups on the appropriateness of the measures and the degree of achievement of these measures; close correlation appears to exist between the ratings of the objective areas and their associated measures; and, finally, there was consensus among the respondents that all universities were performing poorly on the most highly rated objective areas. The results and conclusions of the study were utilised to draw up some recommendations which might be useful to decision-makers in achieving their institutional objectives.

The Water-Energy-Agriculture nexus in Jordan : A case study on As-Samra wastewater treatment plant in the LowerJordan River BasinBelda Gonzalez, Alberto January 2018 (has links)
Historically, water, energy and agricultural resources have been naturally scarce in Jordan, but current economic, demographic, geopolitical and environmental conditions are aggravating the situation. The influxes of refugees are increasing the already high natural population growth; better economic conditions and living standards are changing consumption and production patterns; surrounding conflicts affect the supply of resources; and negative effects associated to climate change can be noticed already. Therefore, nexus thinking as a basis for integrated and cross-sectorial natural resources management is essential to achieve water, energy and food security, and eventually to move towards a sustainable development of the country. To that end, understanding the existing nexus interlinkages is crucial. This document constitutes a first nexus approach focused on water, energy and agriculture (WEA) sectors in Jordan. The research has adopted a case study method based on literature review to consider different contextual factors, and three levels of study were regarded: national level, Lower Jordan River Basin within Jordanian borders level, and As-Samra WWTP level, which has constituted the case study. Based on an extensive literature review that has resulted in an updated analysis of the current Jordanian context, the main WEA nexus interlinkages have been identified at every level of study. Thirteen future alternative pathways have been proposed, their potential impacts on WEA nexus sectors have been investigated, and related indicators to evaluate these impacts have been suggested. Additionally, three combined pathways have been analyzed in detail. In general, results show that interdependencies between WEA sectors at all levels are strong and projected to intensify in the future, and highlight the critical situation of Jordan in terms of resource management. Inefficiencies and unsustainable uses of natural resources stand out as decisive problems that urge to be solved, and future pathways appear to be potentially harmful for the Jordanian system unless they are included in an integrated nexus-based planning. / Historiskt sett har vatten-, energi- och jordbruksresurser varit naturligt begränsade i Jordanien, men de nuvarande ekonomiska, demografiska, geopolitiska och miljöbetingade förhållandena förvärrar situationen. Inkommande flyktningar ökar den redan höga populationsökningen; bättre ekonomiska förutsättningar och levnadsstandarder ändrar konsumtion- och produktionsmönster; kringliggande konflikter påverkar utbudet av resurser; och negativa effekter associerade med klimatförändringar är redan tydliga. På denna grund så är Nexus en god grund för integrerad och tvärsektoriell förvaltning av naturresurs och vital för att säkerställa resurser för vatten, energi och mat och eventuellt gå mot en hållbar utveckling inom landet. För att åstadkomma det ovannämnda så är förståelse för nuvarande nexus samband avgörande. Denna studie utgör ett tillvägagångssätt för en nexus studie med fokus på vatten, energi och jordbruk (WEA) sektorerna i Jordanien. Arbetet utgår från en fallstudie och baseras på en litteraturstudie som är gjord på tre olika nivåer: nationell, Lower Jordan River Basin inom gränserna av Jordanien och As-Samra vattenreningsverk, sistnämnda utgör fallstudien. Baserat på en omfattande litteraturstudie som resulterat i en uppdaterad analys av Jordaniens situation, så har de huvudsakliga WEA nexus sambanden identifierats för varje nivå. Tretton framtida alternativa utfall har föreslagits, deras potentiella påverkan på WEA sektorerna har undersökts och relaterade indikatorer har föreslagits för att utvärdera deras påverkan. Vidare, tre kombinerade utfall har utvärderats i detalj. Överlag så visar resultaten på starkt ömsesidigt beroende mellan WEA sektorerna på alla nivåer och är beräknad att intensifieras i framtiden, vilket betonar den kritiska situationen Jordanien befinner sig i med avseende på naturresurshantering. Ineffektivt och ohållbart utnyttjande av naturresurser står ut som ett stort problem som kräver en lösning, och framtida utfall tycks vara potentiellt skadliga för Jordanien om de inte inkluderas i en integrerad planering baserat på ett nexus tillvägagångssätt.

Good Water Neighbours : Direct and indirect effects of community engagement on transboundary water cooperation in the Jordan river basinKaufmann, Wanja January 2021 (has links)
The Jordan Valley is a region where water resources are both scarce and disputed. Over a long period of time, the shared water resources in the region have constituted a source of conflict. Meanwhile, these shared resources and the challenges connected to them can also function as a basis for mutual understanding and trust-building, potentially fostering cooperation and sustainable peacebuilding. This thesis explores the potential of different kinds of cooperation efforts on shared water resources promoting such a development, by investigating the relationship between bottom-up local transboundary water cooperation efforts and top-down transboundary cooperation on a national level. The research question, “What direct and likely indirect impacts has the Good Water Neighbours programme had on the adherence to the Article 6 of the Israel-Jordan peace treaty from 1994?”, is examined through a single case study, in which a Multi-Track Water Diplomacy Framework (MTWD) analysis is conducted in order to map and understand key factors affecting water cooperation in the specific transboundary water context in which the Good Water Neighbours programme operates. The indirect impacts are examined through adding an intermediate variable, namely national transboundary water cooperation efforts between Israel and Jordan, operationalised through the regional NGO master plan for sustainable development in the Jordan Valley (released in 2015). The study finds support for the hypothesis that cooperation on the local-international level will lead to trust-building and increased public pressure, creating incentives for national-international cooperation, and thereby increased adherence to the peace treaty. It can however neither reject nor confirm the hypothesis that local-international cooperation will lead to better designed projects, increased acceptance and accountability, in turn increasing the adherence to the peace treaty. The study further concludes that national-international cooperation depends on a sensitive interplay between economy and politics, and that successful transboundary water cooperation requires both bottom-up and top-down engagement.

Opportunities for co-operation between informal youth groups and international non-governmental organisations : a case study of Amman and Zarqa in JordanStrub, Juliane 02 1900 (has links)
Text in English / The study focuses on the interaction between two structures in development cooperation:
the bottom-up approach of Informal Youth Groups (IYGs) and the topdown
approach of International Non-Governmental Organisations (INGOs). These
are considered in the theoretical context of the capability approach.
In the empirical study, conducted in the cities of Amman and Zarqa in Jordan, the
researcher interviewed eleven key members of IYGs to analyse their work mechanisms
and criteria for co-operation. A Focus Group Discussion with members of INGOs
about challenges and opportunities in co-operations with IYGs was conducted,
to complement the literature review of INGO perspectives.
The study provides insights into the work mechanism and co-operation criteria of
IYGs. The interviewees mentioned trust between the parties and sharing vision and
motivation as key requirements. Recommendations for INGOs in their work with local
partners and practical steps for supporting IYGs are given. / Development Studies / M.A. (Development Studies)

An Analysis of Richard M. Weaver's Philosophy and Methodology as Applied to Two of Barbara Jordan's SpeechesHouse, Robert G., fl. 1979- 08 1900 (has links)
This rhetorical thesis analyzes Richard M. Weaver's theories of rhetoric and his methodology for ranking argument types according to their perceived ethicality. Two keynote speeches by former U. S. Representative Barbara Jordan have been subjected to the Weaverian analysis. Ms. Jordan's argument types are characteristic of what Weaver considered ethical oratory. Weaver's axiological judgments and his dogmatic ranking of the hierarchy have generated some criticism from rhetorical scholars. Although this criticism is justified, Weaver's philosophy and methodology provide insight to a given's orator's philosophical perspective. The Weaverian analysis contributes to the understanding of not only the superficial aspects of an address, but also the underlying and sometimes hidden motivations of an orator.

A extensão do modelo estocástico \'Raise and Peel\' com absorção controlada / The extension of the stochastic Raise and Peel model with controlled absorptionCarvajal Jara, Diego Alejandro 19 May 2017 (has links)
O modelo estocástico Raise and Peel é estudado nesta tese. Para isto é utilizado o método de simulação por Monte Carlo junto com os métodos de diagonalização exata e numérica do operador de Liouville. Este modelo estocástico é um modelo de crescimento unidimensional com dois parâmetros livres. Um parâmetro de absorção local e um parâmetro de dessorção não local. Em função destes dois parâmetros se observa um rico diagrama de fase, apresentando regiões massivas, regiões criticamente auto-organizadas, estados quase-estacionários e transições a múltiplos estados absorventes. O principal resultado deste trabalho é ressaltar a existência de células de Jordan no operador de Liouville. Células de Jordan que crescem com o tamanho do sistema e portanto no limite termodinâmico a dinâmica assintótica pode ser mascarada. A nível numérico estas células de Jordan podem levar a errôneas interpretações de fases criticas quando são na realidade fases massivas ou vice-versa. Portanto dependendo da condição inicial observa-se que a presença de células de Jordan pode levar à determinação errônea de expoentes críticos e a observações de tempos de decaimentos excessivamente grandes. Tudo isto ressalta a necessidade de se determinar os expoentes críticos e os tempos de decaimento por diversos métodos, sempre que for possível, além de se controlar o comportamento destas quantidades considerando a evolução do modelo com diferentes condições inicias. Entre outros resultados que obtivemos observamos a existência de estados quase-estacionários com tempos de vida que crescem muito mais rápido que uma lei de potencia do tamanho do sistema. Encontramos o expoente critico dinâmico z=1, no caso da transição a estados multi-absorventes. Este resultado ocorreu tanto nos casos sem absorção como nos casos sem dessorção. O modelo exibe também uma fase rugosa com um expoente de rugosidade próximo de zero quando a taxa de absorção é maior que a taxa dessorção. E finalmente observamos que o modelo estudado em condições periódicas de contorno pode ser enxergado como um modelo KPZ em 1+1 dimensões, sujeito a dois tipos de perturbações. Uma das pertubações sendo relevante e a outra irrelevante. / The stochastic model Raise and Peel is studied in this thesis. we use the Monte Carlo simulation method together with the exact and numerical diagonalization methods of the Liouville operator. This stochastic model is a one-dimensional growth model with two free parameters. A local absorption parameter and a non-local desorption one. As a function of these two parameters, a rich phase diagram is observed, presenting massive regions, critically self-organized regions, quasi-stationary states and transitions to multiple absorbing states. The main result of this work is to emphasize the existence of Jordan cells in the Liouville operator. Jordan cells that grow with the size of the system and therefore in the thermodynamic limit the asymptotic dynamics can be masked. At the numerical level, these Jordan cells can lead to erroneous interpretations of massive phases as being massless critical ones or vice versa. Therefore depending on the initial condition, it is observed that the presence of Jordan cells can lead to the erroneous determination of critical exponents and produce excessively large lifetimes. Due to these effects, it is necessary to determine the critical exponents and the lifetimes by several distinct methods whenever possible, besides controlling the behavior of these quantities, by considering the evolution with different initial conditions. Among other results, we found the existence of quasi-stationary states with lifetimes that grow much faster than a power law of the systems size. We obtained a dynamic critical exponent z = 1 in the transition to multi-absorbent states in both cases without absorption or desorption. The model also shows a rough phase with a roughness exponent close to zero when the absorption rate is higher than the desorption rate. Finally, we observed that the model studied under periodic boundary conditions, can be seen as a KPZ model in 1 + 1 dimensions, under the effect of two perturbations. One of them being relevant and the other one irrelevant.
