CloudMPL:a domain specific language for describing management policies for an autonomic cloud infrastructure

To benefit from the advantages that Cloud Computing brings to the IT industry, management policies must be implemented as a part of the operation of the Cloud. Among others, for example, the specification of policies can be used for the management of energy to reduce the cost of running the IT system or also for security policies while handling privacy issues of users. As cloud platforms are large, manual enforcement of policies is not scalable. Hence, autonomic approaches for management policies have recently received a considerable attention. These approaches allow specification of rules that are executed via rule-engines. The process of rules creation starts by the interpretation of the policies drafted by high-rank managers. Then, technical IT staff translate such policies to operational activities to implement them. Such process can start from a textual declarative description and after numerous steps terminates in a set of rules to be executed on a rule engine. To simplify the steps and to bridge the considerable gap between the declarative policies and executable rules, we propose a domain-specific language called CloudMPL. We also design a method of automated transformation of the rules captured in CloudMPL to the popular rule-engine Drools. As the policies are changed over time, code generation will reduce the time required for the implementation of the policies. In addition, using a declarative language for writing the specifications is expected to make the authoring of rules easier. We demonstrate the use of the CloudMPL language into a running example extracted from a management energy consumption case study.

An investigation into the comparable effectiveness of two tests of writing administered to college-level English as a Second Language students: The Computerized Placement Test and holistically scored essay exams

This dissertation describes the findings and implications of a correlational analysis. Scores earned on the Computerized Placement Test (CPT), sentence skills, were compared to essay scores of advanced English as a Second Language (ESL) students. As the CPT is designed for native speakers of English, it was hypothesized that it could be an invalid or unreliable instrument for non-native speakers. Florida community college students are mandated to take the CPT to determine preparedness, as are students at many other U.S. and Canadian colleges. If incoming students score low on the CPT, they may be required to take up to three semesters of remedial coursework. It is essential that scores earned by non-native speakers of English accurately reflect their ability level. They constitute a large and growing body of non-traditional students enrolled at community colleges.^ The study was conducted at Miami-Dade Community College, Wolfson Campus, fall 1997. Participants included 106 advanced ESL students who took both the CPT sentence skills test and wrote final essay exams. The essay exams were holistically scored by trained readers. Also, the participants took the Placement Articulation Software Service (PASS) exam, an alternative form of the CPT. Scores on the CPT and essays were compared by means of a Pearson product-moment correlation to validate the CPT. Scores on the CPT and the PASS exam were compared in the same manner to verify reliability. A percentage of appropriate placements was determined by comparing essay scores to CPT cutoff score ranges. Finally, the instruments were evaluated by means of independent-samples t-tests for performance differences between gender, age, and first language groups.^ The results indicate that the CPT sentence skills test is a valid and reliable placement instrument for advanced- level ESL students who intend to pursue community college degrees. The correlations demonstrated a substantial relationship between CPT and essay scores and a marked relationship between CPT and PASS scores. Appropriate placements were made in 86% of the cases. Furthermore, the CPT was found to discriminate equally among the gender, age, and first language groups included in this study. ^

Enabling adaptability in service aggregates using transparent shaping techniques

Distributed applications are exposed as reusable components that are dynamically discovered and integrated to create new applications. These new applications, in the form of aggregate services, are vulnerable to failure due to the autonomous and distributed nature of their integrated components. This vulnerability creates the need for adaptability in aggregate services. The need for adaptation is accentuated for complex long-running applications as is found in scientific Grid computing, where distributed computing nodes may participate to solve computation and data-intensive problems. Such applications integrate services for coordinated problem solving in areas such as Bioinformatics. For such applications, when a constituent service fails, the application fails, even though there are other nodes that can substitute for the failed service. This concern is not addressed in the specification of high-level composition languages such as that of the Business Process Execution Language (BPEL). We propose an approach to transparently autonomizing existing BPEL processes in order to make them modifiable at runtime and more resilient to the failures in their execution environment. By transparent introduction of adaptive behavior, adaptation preserves the original business logic of the aggregate service and does not tangle the code for adaptive behavior with that of the aggregate service. The major contributions of this dissertation are: first, we assessed the effectiveness of BPEL language support in developing adaptive mechanisms. As a result, we identified the strengths and limitations of BPEL and came up with strategies to address those limitations. Second, we developed a technique to enhance existing BPEL processes transparently in order to support dynamic adaptation. We proposed a framework which uses transparent shaping and generative programming to make BPEL processes adaptive. Third, we developed a technique to dynamically discover and bind to substitute services. Our technique was evaluated and the result showed that dynamic utilization of components improves the flexibility of adaptive BPEL processes. Fourth, we developed an extensible policy-based technique to specify how to handle exceptional behavior. We developed a generic component that introduces adaptive behavior for multiple BPEL processes. Fifth, we identify ways to apply our work to facilitate adaptability in composite Grid services.

Network construction and graph theoretical analysis of functional language networks in pediatric epilepsy

This dissertation introduces a new approach for assessing the effects of pediatric epilepsy on the language connectome. Two novel data-driven network construction approaches are presented. These methods rely on connecting different brain regions using either extent or intensity of language related activations as identified by independent component analysis of fMRI data. An auditory description decision task (ADDT) paradigm was used to activate the language network for 29 patients and 30 controls recruited from three major pediatric hospitals. Empirical evaluations illustrated that pediatric epilepsy can cause, or is associated with, a network efficiency reduction. Patients showed a propensity to inefficiently employ the whole brain network to perform the ADDT language task; on the contrary, controls seemed to efficiently use smaller segregated network components to achieve the same task. To explain the causes of the decreased efficiency, graph theoretical analysis was carried out. The analysis revealed no substantial global network feature differences between the patient and control groups. It also showed that for both subject groups the language network exhibited small-world characteristics; however, the patient's extent of activation network showed a tendency towards more random networks. It was also shown that the intensity of activation network displayed ipsilateral hub reorganization on the local level. The left hemispheric hubs displayed greater centrality values for patients, whereas the right hemispheric hubs displayed greater centrality values for controls. This hub hemispheric disparity was not correlated with a right atypical language laterality found in six patients. Finally it was shown that a multi-level unsupervised clustering scheme based on self-organizing maps, a type of artificial neural network, and k-means was able to fairly and blindly separate the subjects into their respective patient or control groups. The clustering was initiated using the local nodal centrality measurements only. Compared to the extent of activation network, the intensity of activation network clustering demonstrated better precision. This outcome supports the assertion that the local centrality differences presented by the intensity of activation network can be associated with focal epilepsy.^

An ethnographic investigation into gender and language in the Northern Ireland Assembly

This paper investigates the extent to which the negative evaluation of one of the women Ministers in the Northern Ireland Assembly can be attributed to gender. Interviews with politicians as well as the Minister herself illuminate this discussion by identifying the ‘gendered discourses’ that are drawn upon when describing the Minister’s communicative style in debates. Close analyses of transcripts of debates offer a description of some elements of this style, and find that while the Minister is confrontational in debates and ‘stands her ground’, she does not take part in illegal interventions that disrupt the debate floor and are characteristic of the Assembly as a whole. Although the construction of the Minister’s unpopularity can be attributed to a complex interplay of factors, it can be concluded that it is partly the way she draws on gendered linguistic resources that leads her to be negatively judged by her peers.

Receptive Vocabulary of CLIL and Non-CLIL Primary and Secondary School Learners

CLIL instruction has been reported to be beneficial for foreign language vocabulary learning since CLIL students show higher vocabulary profiles than students of their same age in traditional EFL contexts. However, to our knowledge, the receptive vocabulary knowledge of CLIL and non-CLIL learners at the end of primary and secondary education has not been examined yet. Hence, this study aims at comparing the receptive vocabulary size 79 CLIL primary learners with the receptive vocabulary knowledge of 331 non-CLIL learners at the end of primary and secondary school. Sex-based differences were also analysed. The 2k Vocabulary Levels Test (VLT) was used for the purposes of the study. Results revealed that learners’ receptive vocabulary sizes lie within the most frequent 1000 words, non-CLIL secondary school students throw better results than primary students but the differences between the secondary group and the CLIL group are not statistically significant. As for sex-based differences, we found no significant differences among the groups. These findings led us to believe that the CLIL approach offers a benefit for vocabulary acquisition since CLIL learners have been exposed to the foreign language for a shorter period of time and the results are quite similar to their non-CLIL secondary school partners.

Establishing an EGFR mutation screening service for non-small cell lung cancer - sample quality criteria and candidate histological predictors.

INTRODUCTION: EGFR screening requires good quality tissue, sensitivity and turn-around time (TAT). We report our experience of routine screening, describing sample type, TAT, specimen quality (cellularity and DNA yield), histopathological description, mutation result and clinical outcome. METHODS: Non-small cell lung cancer (NSCLC) sections were screened for EGFR mutations (M+) in exons 18-21. Clinical, pathological and screening outcome data were collected for year 1 of testing. Screening outcome alone was collected for year 2. RESULTS: In year 1, 152 samples were tested, most (72%) were diagnostic. TAT was 4.9 days (95%confidence interval (CI)=4.5-5.5). EGFR-M+ prevalence was 11% and higher (20%) among never-smoking women with adenocarcinomas (ADCs), but 30% of mutations occurred in current/ex-smoking men. EGFR-M+ tumours were non-mucinous ADCs and 100% thyroid transcription factor (TTF1+). No mutations were detected in poorly differentiated NSCLC-not otherwise specified (NOS). There was a trend for improved overall survival (OS) among EGFR-M+ versus EGFR-M- patients (median OS=78 versus 17 months). In year 1, test failure rate was 19%, and associated with scant cellularity and low DNA concentrations. However 75% of samples with poor cellularity but representative of tumour were informative and mutation prevalence was 9%. In year 2, 755 samples were tested; mutation prevalence was 13% and test failure only 5.4%. Although samples with low DNA concentration (2.2 ng/μL), the mutation rate was 9.2%. CONCLUSION: Routine epidermal growth factor receptor (EGFR) screening using diagnostic samples is fast and feasible even on samples with poor cellularity and DNA content. Mutations tend to occur in better-differentiated non-mucinous TTF1+ ADCs. Whether these histological criteria may be useful to select patients for EGFR testing merits further investigation.

La recherche montre que le théâtre éducatif donne aux élèves la possibilité d’utiliser leurs compétences linguistiques en les préparant pour des situations réelles. Il leur donne aussi l’occasion de découvrir toutes les émotions et tous les mouvements physiques qui font partie d’une langue vivante.

A Provenance-Aware Policy Language (cProvl) and a Data Traceability Model (cProv) for the Cloud

Provenance plays a pivotal in tracing the origin of something and determining how and why something had occurred. With the emergence of the cloud and the benefits it encompasses, there has been a rapid proliferation of services being adopted by commercial and government sectors. However, trust and security concerns for such services are on an unprecedented scale. Currently, these services expose very little internal working to their customers; this can cause accountability and compliance issues especially in the event of a fault or error, customers and providers are left to point finger at each other. Provenance-based traceability provides a mean to address part of this problem by being able to capture and query events occurred in the past to understand how and why it took place. However, due to the complexity of the cloud infrastructure, the current provenance models lack the expressibility required to describe the inner-working of a cloud service. For a complete solution, a provenance-aware policy language is also required for operators and users to define policies for compliance purpose. The current policy standards do not cater for such requirement. To address these issues, in this paper we propose a provenance (traceability) model cProv, and a provenance-aware policy language (cProvl) to capture traceability data, and express policies for validating against the model. For implementation, we have extended the XACML3.0 architecture to support provenance, and provided a translator that converts cProvl policy and request into XACML type.

Évaluation du programme aux âgés au Centre de Services Sociaux du Centre du Québec, succursale de Drummondville : une étude portant sur l'évaluation par objectif d'un programme de service

Notre choix d'étude s'est arrêté sur une méthode évaluative afin de nous familiariser avec ce processus et en faire un usage courant à tous les programmes dans lesquels nous sommes impliqués de par nos fonctions. Cette étude vise à évaluer si les objectifs du programme aux âgés du Centre de Services Sociaux du Centre du Québec, élaborés par la direction des services professionnels, ont été atteints, quels impacts ils ont eu sur la communauté âgée du territoire de la succursale de Drummondville, et voir ensuite les améliorations à y apporter. Il s'agit de faire une analyse de type évaluatif afin de connaître l'effet du programme aux âgés sur la population concernée. Après l'étude sommaire de quelques modèles d'évaluation, celui de Perry L. Levinson nous semble le plus apte à répondre aux objectifs de l'étude et aux moyens dont nous disposons. À l'aide de ce modèle, nous pourrons vérifier à combien de personnes âgées des Services ont été rendus, si la stratégie d'action a été efficace, si les ressources humaines ont été bien utilisées et en nombre suffisant, s'il y a eu des résultats imprévus et lesquels. L'étude porte sur deux ans d'opération, soit du 1er novembre 1977 au 31 octobre 1979. Après avoir établi les objectifs du programme aux âgés, nous fournirons des données sur la description du territoire et sur la population âgée, nous expliquerons les deux organigrammes de fonctionnement, soit celui avant 1977 et celui après 1977, qui ont eu des répercussions sur l'opérationalisation dudit programme. Nous traiterons des intrants injectés et de la population âgée qui a été atteinte. Le lecteur pourra retrouver une synthèse de l'évaluation du programme faite par l'ensemble des professionnels qui ont travaillé à sa réalisation ainsi qu'une analyse de variables intermédiaires.

Analyse descriptive de deux filiales de service social : Roberval et Dolbeau

Il s'agit de la présentation de la description de deux filiales de service social dont l'une héritait d'orientations traditionnelles et l'autre débutait selon l'esprit de la loi des Services de Santé et des Services Sociaux. Ce travail se situe au niveau d'une action précise dans le domaine du service social. La première partie sera consacrée à une critique sommaire des objectifs et du fonctionnement de l'agence de Service Social du Diocèse de Chicoutimi des années 1970-72. Je retiendrai trois principes, soit l'accessibilité des services, la participation de la population et la flexibilité des interventions qui nous guideront dans l'orientation d'une filiale à Dolbeau. La deuxième partie consistera en une description comparative des objectifs et du fonctionnement entre deux filiales, soit celle de Roberval, modèle de la filiale traditionnelle en évolution et la nouvelle filiale, celle de Dolbeau, ouverte au début de l'année 1972, et orientée selon l'esprit de la nouvelle loi des Services de Santé et des Services Sociaux. Cette étude comparative nous permettra d'élaborer des hypothèses d'évaluation d'objectifs, de personnel et de rendement pour les deux filiales concernées, et c'est ce qui complétera le présent travail dans la troisième partie.

Online MBPeT dashboard : enabling performance testing as a service in the cloud

In this thesis, tool support is addressed for the combined disciplines of Model-based testing and performance testing. Model-based testing (MBT) utilizes abstract behavioral models to automate test generation, thus decreasing time and cost of test creation. MBT is a functional testing technique, thereby focusing on output, behavior, and functionality. Performance testing, however, is non-functional and is concerned with responsiveness and stability under various load conditions. MBPeT (Model-Based Performance evaluation Tool) is one such tool which utilizes probabilistic models, representing dynamic real-world user behavior patterns, to generate synthetic workload against a System Under Test and in turn carry out performance analysis based on key performance indicators (KPI). Developed at Åbo Akademi University, the MBPeT tool is currently comprised of a downloadable command-line based tool as well as a graphical user interface. The goal of this thesis project is two-fold: 1) to extend the existing MBPeT tool by deploying it as a web-based application, thereby removing the requirement of local installation, and 2) to design a user interface for this web application which will add new user interaction paradigms to the existing feature set of the tool. All phases of the MBPeT process will be realized via this single web deployment location including probabilistic model creation, test configurations, test session execution against a SUT with real-time monitoring of user configurable metric, and final test report generation and display. This web application (MBPeT Dashboard) is implemented with the Java programming language on top of the Vaadin framework for rich internet application development. The Vaadin framework handles the complicated web communications processes and front-end technologies, freeing developers to implement the business logic as well as the user interface in pure Java. A number of experiments are run in a case study environment to validate the functionality of the newly developed Dashboard application as well as the scalability of the solution implemented in handling multiple concurrent users. The results support a successful solution with regards to the functional and performance criteria defined, while improvements and optimizations are suggested to increase both of these factors.

Quichua-Spanish language contact in Salcedo, Ecuador: revisiting media lengua syncretic language practices

The purpose of the current thesis is to develop a better understanding of the interaction between Spanish and Quichua in the Salcedo region and provide more information for the processes that might have given rise to Media Lengua, a ‘mixed’ language comprised of a Quichua grammar and Spanish lexicon. Muysken attributes the formation of Media Lengua to relexification, ruling out any influence from other bilingual phenomena. I argue that the only characteristic that distinguishes Media Lengua from other language contact varieties in central Ecuador is the quantity of the overall Spanish borrowings and not the type of processes that might have been employed by Quichua speakers during the genesis of Media Lengua. The results from the Salcedo data that I have collected show how processes such as adlexification, code-mixing, and structural convergence produce Media Lengua-type sentences, evidence that supports an alternative analysis to Muysken’s relexification hypothesis. Overall, this dissertation is developed around four main objectives: (1) to describe the variation of Spanish loanwords within a bilingual community in Salcedo; (2) to analyze some of the prominent and recent structural changes in Quichua and Spanish; (3) to determine whether Spanish loanword use can be explained by the relationship consultants have with particular social categories; and (4) to analyze the consultants’ language ideologies toward syncretic uses of Spanish and Quichua. Overall, 58% of the content words, 39% of the basic vocabulary, and 50% of the subject pronouns in the Salcedo corpus were derived from Spanish. When compared to Muysken’s description of highlander Quichua in the 1970’s, Spanish loanwords have more than doubled in each category. The overall level of Spanish loanwords in Salcedo Quichua has grown to a level between highlander Quichua in the 1970’s and Media Lengua. Similar to Spanish’s lexical influence in Media Lengua, the increase of Spanish borrowings in today’s rural Quichua can be seen in non-basic and basic vocabularies as well as the subject pronoun system. Significantly, most of the growth has occurred through forms of adlexification i.e., doublets, well-established borrowings, and cultural borrowings, suggesting that ‘ordinary’ lexical borrowing is also capable of producing Media Lengua-type sentences. I approach the second objective by investigating two separate phenomena related to structural convergence. The first examines the complex verbal constructions that have developed in Quichua through Spanish loan translations while the second describes the type of Quichua particles that are attached to Spanish lexemes while speaking Spanish. The calquing of the complex verbal constructions from Spanish were employed when speaking standard Quichua. Since this standard form is typically used by language purists, I argue that their use of calques is a strategy of exploiting the full range of expression from Spanish without incorporating any of the Spanish lexemes which would give the appearance of ‘contamination’. The use of Quichua particles in local varieties of Spanish is a defining characteristic of Quichuacized Spanish, spoken most frequently by women and young children in the community. Although the use of Quichua particles was probably not the main catalyst engendering Media Lengua, I argue that its contribution as a source language to other ‘mixed’ varieties, such as Media Lengua, needs to be accounted for in descriptions of BML genesis. Contrary to Muysken’s representation of relatively ‘unmixed’ Spanish and Quichua as the two source languages of Media Lengua, I propose that local varieties of Spanish might have already been ‘mixed’ to a large degree before Media Lengua was created. The third objective attempts to draw a relationship between particular social variables and the use of Spanish loanwords. Whisker Boxplots and ANOVAs were used to determine which social group, if any, have been introducing new Spanish borrowings into the bilingual communities in Salcedo. Specifically, I controlled for age, education, native language, urban migration, and gender. The results indicate that none of the groups in each of the five social variables indicate higher or lower loanword use. The implication of these results are twofold: (a) when lexical borrowing occurs, it is immediately adopted as the community-wide norm and spoken by members from different backgrounds and generations, or (b) this level of Spanish borrowing (58%) is not a recent phenomenon. The fourth and final objective draws on my ethnographic research that addresses the attitudes of syncretic language use. I observed that Quichuacized Spanish and Hispanicized Quichua are highly stigmatized varieties spoken by the country’s most marginalized populations and families, yet within the community, syncretic ways of speaking are in fact the norm. It was shown that there exists a range of different linguistic definitions for ‘Chaupi Lengua’ and other syncretic language practices as well as many contrasting connotations, most of which were negative. One theme that emerged from the interviews was that speaking syncretic varieties of Quichua weakened the consultant’s claim to an indigenous identity. The linguistic and social data presented in this dissertation supports an alternative view to Muysken’s relexification hypothesis, one that has the advantage of operating with well-precedented linguistic processes and which is actually observable in the present-day Salcedo area. The results from the study on lexical borrowing are significant because they demonstrate how a dynamic bilingual speech community has gradually diversified their Quichua lexicon under intense pressure to shift toward Spanish. They also show that Hispanicized Quichua (Quichua with heavy lexical borrowing) clearly arose from adlexification and prolonged lexical borrowing, and is one of at least six identifiable speech styles found in Salcedo. These results challenge particular interpretations of language contact outcomes, such as, ones that depict sources languages as discrete and ‘unmixed.’ The bilingual continuum presented in this thesis shows on the one hand, the range of speech styles that are accessible to different speakers, and on the other hand, the overlapping, syncretic features that are shared among the different registers and language varieties. It was observed that syncretic speech styles in Salcedo are employed by different consultants in varied interactional contexts, and in turn, produce different evaluations by other fellow community members. In the current dissertation, I challenge the claim that relexification and Media Lengua-type sentences develop in isolation and without the influence of other bilingual phenomena. Based on Muysken's Media Lengua example sentences and the speech styles from the Salcedo corpus, I argue that Media Lengua may have arisen as an institutionalized variant of the highly mixed "middle ground" within the range of the Salcedo bilingual continuum discussed above. Such syncretic forms of Spanish and Quichua strongly resemble Media Lengua sentences in Muysken’s research, and therefore demonstrate how its development could have occurred through several different language contact processes and not only through relexification.

Guided portfolio writing as a scaffold for reflective learning in in-service contexts: a case study

Language is widely recognized as an inescapable mediating tool for professional learning, and with this text we want to contribute to a better understanding of the particular role that guided writing can play in in-service professional reflective learning. We analysed one pre-school teacher’s written portfolio, the construction of which was guided to scaffold deep thinking about (and the transference of theory into) practice during participation in an in-service program about language education. Our case study shows that the writing process sustained robust learning about professional knowing, doing and learning itself: The teacher elaborated an integrative ethical understanding of the discussed theory, fully experienced newly informed practices and assessed her own learning by using theory to confront her previous knowledge and practices. Throughout the portfolio, the learning stance revealed by her voice varied accordingly. The study illustrates the potential of guided writing to scaffold reflective learning in in-service contexts.

Recent educational changes at higher educational level in Pakistan: English language teachers' perceptions and practices

Higher Education Institutes (HEIs) of any country could be a source of providing professionals to the country in many fields. By doing so, HEIs could play a pivotal role in the economic growth of the country. In Pakistan, it seems that, in the wake of this realization, steps have been taken to reform Higher Education. Drawing on the Triple I model of educational change covering Initiation, Implementation and Institutionalization (Fullan, 2007) this study focuses on the planning and implementation of reforms in the Education system of Pakistan at higher education level that have been introduced by the Higher Education Commission (HEC) since its inception in 2002. Kennedy’s model of hierarchical subsystems affecting innovation and Chin and Benne’s (1985) description of strategies for implementing change also provided guidelines for analyzing the changes in education in the country to highlight the role that the authorities expect the language teacher to play in the process of implementing these changes. A qualitative method is followed in this study to gather data from English language teachers at three universities of the Khyber Pakhtunkhwa province of Pakistan. A questionnaire was developed to look into the perceptions of English language teachers regarding the impact of these reforms. This was followed up by interviews. Responses from 28 teachers were received through questionnaire out of which 9 teachers were interviewed for detailed analysis of their perceptions. Thematic Content analysis was used to analyze and interpret the data. Some of the most significant changes that the respondents reported knowledge of included the introduction of Semester System, extending the Bachelors degree to four years from two years, promotion of research culture, and increased teachers’ autonomy in classroom practices. Implications of these reforms for English teachers’ professional development were also explored. The data indicate that the teachers generally have a positive attitude towards the changes. However, the data also show concerns that teachers have about the practical effectiveness of these changes in improving English language teaching and learning in Pakistani Universities. Some of the areas of concern are worries regarding resources, the assessment system, the number of qualified teachers, and instability in the educational policy. They are concerned about the training facilities and quality of the professional training available to them. Moreover, they report that training opportunities for their professional development are not available to all the teachers equally. Despite the HEC claims of providing regular training opportunities, the majority of the teachers did not receive any formal training in the last three years, while some teachers were able to access these opportunities multiple times. Through the recent reforms HEC has empowered the teachers in conducting the learning/teacher processes but this extra power has reduced their accountability and they can exercise these powers without any check on them. This empowerment is limited to the classroom and there appears to be no or minimal involvement in decision making at the top level of policy making. Such lack of involvement in the policy decisions seems to be generating a lack of sense of ownership among the teachers (Fullan 2003a:6). Although Quality Enhancement Cells have been developed in the universities to assure the desired quality of education, they might need a more active role to contribute in achieving the level of enhancement in education expected from them. Based on the perceptions of the respondents of this study and the review of the relevant literature, it is argued that it is unlikely for the reforms to be institutionalized if teachers are not given the right kind of awareness at the initiation stage and are not prepared at the implementation stage to cope with the challenge of a complex process. The teachers participating in this study, in general, have positive and enthusiastic attitudes towards most of the changes, in spite of some reservations. It could also be interesting to see if the power centers of the Pakistani Higher Education appreciate this enthusiasm and channel it for a strong Higher Education system in the country.
