Semantic discovery and reuse of business process patterns

Patterns currently play an important role in modern information systems (IS) development and their use has mainly been restricted to the design and implementation phases of the development lifecycle. Given the increasing significance of business modelling in IS development, patterns have the potential of providing a viable solution for promoting reusability of recurrent generalized models in the very early stages of development. As a statement of research-in-progress this paper focuses on business process patterns and proposes an initial methodological framework for the discovery and reuse of business process patterns within the IS development lifecycle. The framework borrows ideas from the domain engineering literature and proposes the use of semantics to drive both the discovery of patterns as well as their reuse

Assessing the psychometric properties of the adult learner self-directedness scale

This research project examined the psychometric properties of the adult learner self-directedness scale (ALSDS). The study assessed the construct validity and reliability of the scale as a measure of adult learner self-directedness for diverse groups of adult learners in the South African open, distance and e-learning higher education (ODeLHE) context. The study also assessed whether the factorial structure of the ALSDS was equivalent for adult learners across gender, race and age groups. Furthermore, the study assessed whether the various socio-demographic groups differed significantly on the sub-scale dimensions of the ALSDS; and explored whether a range of socio-biographical factors predicted adult learner self-directedness. This doctoral study has extended the student’s initial exploratory master’s study on the development and factorial structure of the ALSDS that involved a stratified random sample (N = 1 102) of ODeLHE adult learners. The secondary data set involved a random subsample of n = 747 of the original master’s sample data set. Exploratory structural equation modelling (ESEM), exploratory factor analysis (EFA) and confirmatory factor analysis (CFA) revealed a three-factor solution for the ALSDS, with 15 items loading onto the three factors. The results provided evidence of the construct (convergent and discriminant) validity and internal consistency reliability of the three-factor ALSDS, including the construct equivalence of the scale’s factorial structure across the gender, race and age groups. Significant differences between age, race and gender groups were observed regarding the scale sub-dimensions. The study advances theory on adult learner self-directedness in ODeLHE contexts and contributed evidence of the validity and reliability of a shortened version of the ALSDS as a useful measure of adult learner self-directedness. Psychometric shortcomings to be addressed in future research were also directedness. Psychometric shortcomings to be addressed in future research were also highlighted. Practically, the study highlighted assessing adult learners’ success orientation in ODeLHE, active academic activity and strategic utilisation of resources as aspects of enhancing their self-directedness. Support practices should be considered for especially females, black Africans and younger learner cohorts. ODeLHE practices should also consider learners’ mark for English, gender, access to library, number of modules and who students support financially as factors influencing learners’ level of self-directedness.Abstract/summary in English, Afrikaans and isiZuluDie navorsingsprojek het die psigometriese eienskappe van die selfgerigtheidskaal vir die volwasse leerder (ALSDS) ondersoek. Die studie het die konstruk-geldigheid en -betroubaarheid van die skaal geassesseer as 'n maatstaf van selfgerigtheid by volwasse leerders vir diverse groepe van volwasse leerders in die Suid-Afrikaanse ope, afstands- en e-leer-hoëronderwyskonteks (ODeLHE). Die studie het ook geassesseer of die fakulteitstruktuur van die ALSDS gelykstaande was vir volwasse leerders oor geslags-, rasse- en ouderdomsgroepe heen. Verder het die studie geassesseer of die verskeie sosiodemografiese groepe beduidend verskil het op die subskaal-dimensies van die ALSDS en ondersoek of 'n reeks sosiobiografiese faktore selfgerigtheid by volwasse leerders voorspel het. Hierdie doktorale studie het uitgebrei op die student se aanvanklike verkennende meesterstudie oor die ontwikkeling en fakulteitstruktuur van die ALSDS wat 'n gestratifiseerde ewekansige steekproef van ODeLHE-volwasse leerders behels het (N = 1 102). Die sekondêre datastel het 'n ewekansige substeekproef behels van n = 747 van die oorspronklike meestersteekproef-datastel. Verkennende strukturele vergelykingsmodellering, verkennende faktorontleding en bekragtigende faktorontleding het 'n driefaktor-oplossing vir die ALSDS onthul, met 15 items wat op die drie faktore gelaai is. Die resultate verskaf bewyse van die konstruk (konvergerende en diskriminerende) geldigheid en interne konsekwentheid en betroubaarheid van die driefaktor-ALSDS, insluitende die konstruk-ekwivalensie van die skaal se fakulteitstruktuur oor die geslags, rasse- en ouderdomsgroepe heen. Beduidende verskille tussen ouderdoms-, rasse- en geslagsgroepe is waargeneem rakende die skaalsubdimensies. Die studie bevorder teorie oor selfgerigtheid by volwasse leerders in ODeLHE-kontekste en dra bewyse van die geldigheid en betroubaarheid van 'n verkorte weergawe van die ALSDS as 'n nuttige maatstaf van selfgerigtheid by volwasse leerders. Psigometriese tekortkomings wat in toekomstige navorsing hanteer kan word, is ook beklemtoon. Prakties gesproke beklemtoon die studie die assessering van volwasse leerders se sukses-oriëntering in ODeLHE, aktiewe akademiese aktiwiteit en strategiese gebruik van hulpbronne as aspekte om hul selfgerigtheid te bevorder. Ondersteuningspraktyke moet oorweeg word vir veral vroue, swart Afrikaners en jonger leerderkohorte. ODeLHE-praktyke moet ook leerders se punt vir Engels, geslag, toegang tot 'n biblioteek, aantal modules en wie studente finansieel ondersteun, oorweeg as faktore wat leerders se vlak van selfgerigtheid beïnvloed.Le projekthi yocwaningo, ihlola ama-psychometric properties of the adult learner self-directedness scale (ALSDS). Ucwaningo luhlola i-construct validity nokuthembeka kwe-scale njengendlela yokukala i-adult self-directedness kumaqembu ehlukene abafundi abadala kwisimo semfundo evulekile lapho abantu abafunda bekude esibizwa nge-South African open, distance and e-learning higher education (ODeLHE). Ucwaningo lubuye lwahlola nokuthi ngabe isimo ngamaqiniso e-ALSDS siyalingana yini kubafundi abadala kumaqembu obubili, bezinhlanga ezehlukene ngokwebala kanye nabantu beminyaka ehlukene. Kanti futhi okunye, ucwaningo, luhlola ukuthi ngabe amaqembu emikhakha ehlukene ngokwe-sociodemographic ehlukene kakhulu maqondana nama-dimention e-ALSDS acutshungulwayo ukuthi ngabe ama-range emibandela yama-sociodemographic abonelela noma aqagela inqubo ye-adult leaner self-directedness. Lolu cwaningo lweziqu ze-doctoral study lubheke nocwaningo lokuqala lwabafundi be-masters ngentuthuko yesakhiwo se-factoral structure ye-ALSDS ebandakanye amasampuli akhethwe nje ngaphandle kokukhetha noma ukubeka imibandela ethize, okwaziwa nge-stratified random sample ye (N = 1 102) yabafundi abadala be-ODeLHE. Isethi ye-data yesekondari yona ibandakanya i-random subsample of n = 747 yesethi ye-data yabafundi bokuqala be-masters. I-Exploratory structural equation modelling, i-exploratory factor analysis kanye ne-confirmatory factor analysis eziveze izixazululo ezintathu ngama-ALSDS kuma-ayithemu angu 15 afakelwe kuma-factor amathathu. Imiphumela iveza ubufakazi be-construct (i-convergent and discriminant) validity kanye ne-internal consistency reliability yama-factor amathathu e-ALSDS abandakanya i- ix construct equivalence ye-scale's factorial structure, ukunqamuleza kumaqembu ngobulili, izinhlanga ezehlukene ngokwebala kanye neminyaka yobudala ehlukene. Umehluko osemqoka phakathi kweminyaka yobudala, izinhlanga ezehlukene ngokwebala kanye namaqembu eminyaka ehlukene uye wabonakaka maqondana ne-scale sub-dimensions. Ucwaningo luqhubela phambili ithiyori kwizimo zabafundi zokuziqhuba ngokufunda ezibizwa i-adult learner self-directedness kwi-ODeLHE, kanti futhi ithela esivivaneni kwi-reliability ye-version efinyeziwe ye-ALSDS njengesikali esiwusizo kwi-adult learner self-directedness. Okuyizihibe nge-psychometric okufanele kubhekwane nakho ngocwaningo lwangekusasa, kuye kwavezwa kwagqanyiswa. Ngokubonakala ngendlela ebambekayo, ucwaningo lugqamise ukuhlolwa kwempumelelo yabafundi abadala kwi-ODeLHE, umsebenzi omatasatasa we-akhademiki kanye nokusetshenziswa ngendlela yamasu abambekayo kwemithombo njengengxenye yokuthuthukisa i-self-directedness. Izinkambiso zokusekela kumele zibonelelwe, ikakhulukazi kwabesimame, abamnyama bama-Afrika kanye nabafundi abasebasha.

Mechanical operations of the spirit : the Protestant object in Swift and Defoe

textThis study revises a dominant narrative of the eighteenth-century, in which a secular modernity emerges in opposition to religious belief. It argues that a major challenge for writers such as Jonathan Swift and Daniel Defoe, and for English subjects generally, was to grasp the object world--including the modern technological object--in terms of its spiritual potential. I identify disputes around the liturgy and common prayer as a source of a folk psychology concerning mental habits conditioned by everyday interactions with devotional and cultural objects. Swift and Defoe therefore confront even paradigmatically modern forms (from trade items to scientific techniques) as a spiritual ecology, a network of new possibilities for practical piety and familiar forms of mental-spiritual illness. Texts like A Tale of a tub (1704) and Robinson Crusoe (1719) renew Reformation ideals for the laity by evaluating technologies for governing a nation of souls. Swift and Defoe's Protestantism thus appears as an active guide to understanding emotions and new experience rather than a static body of doctrine. Current historiography neglects the early modern sense that sectarian objects and rituals not only discipline religious subjects, but also provoke ambivalence and anxiety: Swift's Tale diagnoses Catholic knavery and Puritan hypocrisy as neurotic attempts to extract pleasure from immiserating styles of material praxis. Crusoe, addressed to more radical believers in spaces of trade, sees competent spiritual, scientific and commercial practice on the same plane, as techniques for overcoming fetishistic desires. Swift's orthodoxy of enforced moderation and Defoe's oddly worldly piety represent likeminded formulae for psychic reform, and not--as often alleged--conflicts between sincere belief and political or commercial interests. Gulliver's travels (1726) and A Journal of the plague year (1722) also link mind and governance through different visions of Protestant polity. Swift sees alienation from the national church--figured by a Crusoe or Gulliver--as refusal of common sense and problem solving. Defoe points to religious schism, exemplified by dissenters' exclusion from state church statistics, as a moral and medical failure: the city risks creating selfish citizens who also may overlook data needed to combat the plague.Englis

Curriculum and collective consciousness : speculations on individualism, community and cosmos

This study joins the work of a number of contemporary curriculum theorists who are attempting to foster a "language of possibility" for education. The impetus for this study is derived from, and the first chapter addresses, the paradoxical modernist situation where both increasing technological innovation and individualist approaches to development and competence have resulted in a world poised on the brink of catastrophic nuclear war and social disintegration, alienation. This study, then, examines the emergence of modernist, technical rationality; social, political and philosophical frameworks which situate this present historical moment in incommensurable paradigms; and the curricular implications of modernist culture. Curriculum theory, as it is approached in this study, is portrayed as an interpretative science - a critical and expressive endeavor which attempts to promote human understanding and meaningful action in both practical and liberative intents. The second chapter draws upon the recent re-emergence of philosophical hermeneutics as not only a research methodology, but as a sophisticated and systematic interpretation of the normative dimensions of human interests and knowledge

Proceedings of the tenth international conference Models in developing mathematics education: September 11 - 17, 2009, Dresden, Saxony, Germany

This volume contains the papers presented at the International Conference on “Models in Developing Mathematics Education” held from September 11-17, 2009 at The University of Applied Sciences, Dresden, Germany. The Conference was organized jointly by The University of Applied Sciences and The Mathematics Education into the 21st Century Project - a non-commercial international educational project founded in 1986. The Mathematics Education into the 21st Century Project is dedicated to the improvement of mathematics education world-wide through the publication and dissemination of innovative ideas. Many prominent mathematics educators have supported and contributed to the project, including the late Hans Freudental, Andrejs Dunkels and Hilary Shuard, as well as Bruce Meserve and Marilyn Suydam, Alan Osborne and Margaret Kasten, Mogens Niss, Tibor Nemetz, Ubi D’Ambrosio, Brian Wilson, Tatsuro Miwa, Henry Pollack, Werner Blum, Roberto Baldino, Waclaw Zawadowski, and many others throughout the world. Information on our project and its future work can be found on Our Project Home Page http://math.unipa.it/~grim/21project.htm It has been our pleasure to edit all of the papers for these Proceedings. Not all papers are about research in mathematics education, a number of them report on innovative experiences in the classroom and on new technology. We believe that “mathematics education” is fundamentally a “practicum” and in order to be “successful” all new materials, new ideas and new research must be tested and implemented in the classroom, the real “chalk face” of our discipline, and of our profession as mathematics educators. These Proceedings begin with a Plenary Paper and then the contributions of the Principal Authors in alphabetical name order. We sincerely thank all of the contributors for their time and creative effort. It is clear from the variety and quality of the papers that the conference has attracted many innovative mathematics educators from around the world. These Proceedings will therefore be useful in reviewing past work and looking ahead to the future

E-quipped to serve: delivering holistic Christian mission training through e-learning

Developments in Information and Communication Technologies are rapidly breaking down the barriers of time and place that may have previously limited learning to those able to access campus-based programmes. Distance learning, or e-learning, offers exciting opportunities to cross cultural borders and open up the world of education in ways inconceivable even a few years ago. This study considered how e-learning can be used to effectively deliver training to those involved in Christian mission work. Holistic mission training aims to equip the whole person head, heart and hands for Christian service, especially in cross-cultural contexts. Particularly in the Western world, this training has traditionally taken place within face-to-face learning communities, with e-learning s place as a delivery mode being a matter for debate. The research set out to identify and define the key criteria required for the effective delivery of holistic mission training through e-learning and conceptualise those criteria within a framework. A multimethod research design was adopted combining qualitative and quantitative data collection techniques. A systematic literature review was carried out to identify and define the key criteria for effective mission training and effective e-learning and the main challenges in delivering mission training through e-learning, along with potential solutions. Further criteria were found through action research to develop and evaluate a programme of holistic mission training delivered through e-learning. The study contributes to knowledge by identifying for the first time the elements, factors and conditions that can enable holistic mission training to be delivered effectively through e-learning and setting them within a framework to facilitate the development and evaluation of e-learning programmes. The findings highlight principles applicable to different learning situations, cultures and technologies and are largely transferable to other disciplines
