Initial dilemmas in IST research: design science and design research, a clarification of concepts

The inter-disciplinarity of information systems, applied discipline and activity of design, and the study from different paradigms perspectives explains the diversity of problems addressed. The context is broad and includes important issues beyond technology, as the application, use, effectiveness, efficiency and their organizational and social impacts. In design science, the research interest is in contributing to the improvement of the processes of the design activity itself. The relevance of research in design science is associated with the result obtained for the improvement of living conditions in organizational, inter-organizational and Society contexts. In the research whose results are artifacts, the adoption of design research as a process of research is crucial to ensure discipline, rigor and transparency. Based on a literature review, this paper clarifies the terms of design science and design research. This is the main motivation for presenting this paper, determinant for the phase in research in technologies and information systems which are the three research projects presented. As a result the three projects are discussed in relation to the concepts of design science and design research.

Appreciating the power of words and imaginative organizing: A triadic model of ethics practiced in everyday conversations

This thesis provides an alternative framework to analyze power and ethics practiced in everyday conversations, which constitute processes of organizing. Drawing upon narrative frameworks, the analyses of messages posted on an online message board demonstrate people’s imaginative capacity to create relevant stories, in respect of their precise grasp of factual understandings, contextual relevance and evaluative/moral appropriateness, by appropriating others’ words. Based on the empirical analyses, the thesis indicates that studies on power and ethics in organizations can be re-oriented towards appreciating irremediable power imbalances by offering alternative ways of member’s denoting experiences of power.

Determination of the thermal parameters of high-power batteries by local heat

A new approach to the determination of the thermal parameters of high-power batteries is introduced here. Application of local heat flux measurement with a gradient heat flux sensor (GHFS) allows determination of the cell thermal parameters in di_erent surface points of the cell. The suggested methodology is not cell destructive as it does not require deep discharge of the cell or application of any charge/discharge cycles during measurements of the thermal parameters of the cell. The complete procedure is demonstrated on a high-power Li-ion pouch cell, and it is verified on a sample with well-known thermal parameters. A comparison of the experimental results with conventional thermal characterization methods shows an acceptably low error. The dependence of the cell thermal parameters on state of charge (SoC) and measurement points on the surface was studied by the proposed measurement approach.

Interdependence in Southern Africa: an examination of the relations between Zimbabwe and South Africa

Most research on southern Africa focuses on the total dependency of the region's states--Angola, Botswana, Lesotho, Malawi, Mozambique, Swaziland, zambia and Zimbabwe--upon the dominant power, South Africa. This thesis examines the relationship between South Africa and Zimbabwe and argues that these two states are more interdependent than dependency scholars would acknowledge. Although a study of the historical period reveals that dependency theory, as defined by Raul Prebisch, Andre Gunder Frank and A. Valenzuela, is helpful for understanding the development of relations between the two states, it is unable to account for many of the characteristics of the relationship which are found in the contemporary context, especially since 1980. An examination of various economic areas of interaction, including investment, trade and transportation, as well as the political realm, indicates that each state exhibits a degree of dependence upon the other. Thus, it is possible to characterize the relationship as one of "mutual dependence," or interdependence as defined by Robert Keohane and Joseph S. Nye. Interdependence is further examined through the concepts of sensitivity and vulnerability. Sensitivity signifies the ability of a state to respond effectively to policy changes made by another state wi thin a given area of interaction without incurring large costs, while vulnerability denotes that an actor is unable to respond, or only at great cost. By applying these concepts to the relationship between Zimbabwe and South Africa, it is determined that although South Africa tends to be sensitive while Zimbabwe is generally vulnerable, the degrees to which these two states are sensi ti ve and vulnerable varies over time and issue area. As the changes wi thin South Africa start to affect relations wi th the rest of southern Africa, it wi 11 be necessary to understand the interaction between the states from an interdependency perspective if cooperation within the region wi 11 be successful. By appl ying an interdependence framework, this study aims at contributing to the understanding of relations among the countries of southern Africa in general, and between South Africa and Zimbabwe in particular.

Course/instructor evaluation : perspectives of part-time graduate students

This study explored 6 part-time graduate students' perspectives on course/instructor evaluation. The purpose was to explore whether a link exists between the evaluation for course and instructors as contained in the Faculty of Education courselinstructor evaluation form and the needs of part-time students enrolled in that program. The literature review provided contextual information concerning the 3 main subject areas based upon which the research questions were designed: learner needs in the context of part-time graduate students, courselinstructor eval~ation, and the potential lack of congruency between the 2. Using a semistructured interview process, participants identified criteria important or relevant to the evaluation process and incongruent with the course/instructor evaluation form. A qualitative research methodology using a grounded theory approach contributed to the theory on the nature of course evaluation instruments in a graduate program and addressed the notion of where power was situated within the evaluation process. Findings suggested that the concepts of relevance and the instructor's role that participants identified as important in their graduate learning experience were congruent with what they considered important components of the course/instructor evaluation form. Participants noted a lack of congruency between their expectations of a quality graduate learning experience and the format, content, intent, and timing of the evaluation process. The study confirmed that students did want a voice in the evaluation of their learning experience at both the course and program levels.

University Faculty Members’ Understanding of Their Role: Identity, Power, and Silence

This qualitative study was conducted to explore tenured faculty members’ understandings of their roles as professors. Tenure is an institutional means to enact academic freedom, which allows tenured faculty members to investigate topics of their choosing free from external influence. Academic freedom also enables faculty members to be public intellectuals who shape and critique social policies and make knowledge assertions. In effect, the faculty members are institutionally protected to speak truth to power. Purposeful sampling of 9 participants from 2 universities yielded 3 major themes: professorial identity (shaped by such factors as career stage, university culture, and faculty affiliation), professorial power (powers that participants experienced as well as the ways in which they exercised power), and professorial silencing (as a response to fiscal realities coupled with numerous governance issues). While participants were cognizant of the powers that affected their freedoms, they were less aware of the ways in which their position afforded them powers. Subtle but more potent forms of power were at play for tenured professors, but the participants saw themselves as having to work within institutional and financial constraints that limited their freedom to speak out on controversial issues. Faculty members were, thus, silenced and at times chose to self-silence. The context of the present-day university, governance models, and the financial issues affecting universities and departments worked in concert to silence this critical voice in society.

Deconstructing Child Youth Care: an autoethnographic exploration of physical restraints in children’s residential settings

This thesis is written through the front-line perspective of a child/youth worker who has experienced ‘rupture’ in her personal understanding of the Child Youth Care (CYC) practice. Using a collection of personal journal entries written about her individual experiences of CYC education, mentorship/training, front-line residential practice and frequently used interventions, this thesis takes the reader (and the writer) on a discovery of prominent discourses that exist within the residential CYC profession. Focusing on the use of physical restraints on children by residential Child/Youth Workers, this research project utilizes Deconstructive Discourse Analysis and Liberation Psychologies to illustrate a critical examination of power-knowledge and scientific/medical discourses in CYC practice. By focusing on Foucault’s concepts of disciplinary power, binary division and theory of panopticism, the writer seeks to explore a personal reflection and comprehension of how power is used to assert control over children/youth through mental health treatment and physical interventions.

The Supreme Court’s Understanding of Federalism: Efficiency at the Expense of Diversity

This paper is an examination of the Supreme Court of Canada's interpretation of federalism since constitutional repatriation in 1982. It argues that the lure of centralist efficiency is overpowering a fundamentally important part of our federal order: regionalism. The author contends that changes made by the Court to certain fundamental concepts of Canadian constitutional law now provide Parliament with greater latitude than before in the exercise of its legislative powers. According to the author, these changes are disturbing because they are structured so as to preclude consideration of the legitimate concerns of regional polities. Furthermore, he argues that the Court has reinforced the central government's power to regulate the economy, including intraprovincial matters affecting trade, by resorting to highly functional tests that emphasize economic efficiency over other criteria. This, he claims, makes it more difficult to invoke legitimate regional interests that would lead to duplication, overlapping and even, in the eyes of some, inefficiency. The author the focuses on the Court's treatment of environmental protection in an attempt to show the tension between the Court's desire to use a functional approach and the need to recognize regional interests. Finally, through an examination of recent case law, he attemps to demonstrate that the Court's dominant perspective remains functional despite its endorsement of a more community-oriented undestanding of federalism in Secession Reference. If the Court chooses to proceed in this manner, it will alienate regional polities and may encourage them to choose more radical means of asserting their differences. Further, the author argues that strict adherence to the functional effectiveness approach will undermine the very values that federalism is meant to promote.

Integrated Management of Interface Power (IMIP) Framework

La présence importante de plusieurs réseaux sans-fils de différentes portées a encouragée le développement d’une nouvelle génération d’équipements portables sans-fils avec plusieurs interfaces radio. Ainsi, les utilisateurs peuvent bénéficier d’une large possibilité de connectivité aux réseaux sans-fils (e.g. Wi-Fi [1], WiMAX [2], 3G [3]) disponibles autour. Cependant, la batterie d’un nœud mobile à plusieurs interfaces sera rapidement épuisée et le temps d’utilisation de l’équipement sera réduit aussi. Pour prolonger l’utilisation du mobile les standards, des réseaux sans-fils, on définie (individuellement) plusieurs états (émission, réception, sleep, idle, etc.); quand une interface radio n’est pas en mode émission/réception il est en mode sleep/idle où la consommation est très faible, comparée aux modes émission/réception. Pourtant, en cas d’équipement portable à multi-interfaces radio, l’énergie totale consommée par les interfaces en mode idle est très importante. Autrement, un équipement portable équipé de plusieurs interfaces radio augmente sa capacité de connectivité mais réduit sa longévité d’utilisation. Pour surpasser cet inconvénient on propose une plate-forme, qu'on appelle IMIP (Integrated Management of Interface Power), basée sur l’extension du standard MIH (Media Independent Handover) IEEE 802.21 [4]. IMIP permet une meilleure gestion d’énergie des interfaces radio, d’un équipement mobile à multi-radio, lorsque celles-ci entrent en mode idle. Les expérimentations que nous avons exécutées montrent que l’utilisation de IMIP permet d'économiser jusqu'a 80% de l'énergie consommée en comparaison avec les standards existants. En effet, IMIP permet de prolonger la durée d'utilisation d'équipements à plusieurs interfaces grâce à sa gestion efficace de l'énergie.

The typic in Kant’s critique of practical reason : moral judgment and symbolic representation

Comment pouvons-nous représenter un principe moral universel de manière à le rendre applicable à des cas concrets ? Ce problème revêt une forme aiguë dans la philosophie morale d’Emmanuel Kant (1724-1804), tout particulièrement dans sa théorie du jugement moral, car il soutient que l’on doit appliquer la loi morale « suprasensible » à des actions dans le monde sensible afin de déterminer celles-ci comme moralement bonnes ou mauvaises. Kant aborde ce problème dans un chapitre de la Critique de la raison pratique (1788) intitulé « De la typique de la faculté de juger pratique pure » (KpV 5: 67-71). La première partie de la thèse vise à fournir un commentaire compréhensif et détaillé de ce texte important, mais trop peu étudié. Étant donné que la loi morale, en tant qu’Idée suprasensible de la raison, ne peut pas être appliquée directement à des actions dans l’intuition sensible, Kant a recours à une forme particulière de représentation indirecte et symbolique. Sa solution inédite consiste à fournir la faculté de juger avec un « type [Typus] », ou analogue formel, de la loi morale. Ce type est la loi de la causalité naturelle : en tant que loi, il sert d’étalon formel pour tester l’universalisabilité des maximes ; et, en tant que loi de la nature, il peut aussi s’appliquer à toute action dans l’expérience sensible. Dès lors, le jugement moral s’effectue par le biais d’une expérience de pensée dans laquelle on se demande si l’on peut vouloir que sa maxime devienne une loi universelle d’une nature contrefactuelle dont on ferait soi-même partie. Cette expérience de pensée fonctionne comme une « épreuve [Probe] » de la forme des maximes et, par ce moyen, du statut moral des actions. Kant soutient que tout un chacun, même « l’entendement le plus commun », emploie cette procédure pour l’appréciation morale. De plus, la typique prémunit contre deux menaces à l’éthique rationaliste de Kant, à savoir l’empirisme (c’est-à-dire le conséquentialisme) et le mysticisme. La seconde partie de la thèse se penche sur l’indication de Kant que la typique « ne sert que comme un symbole ». Un bon nombre de commentateurs ont voulu assimiler la typique à la notion d’« hypotypose symbolique » présentée dans le § 59 de la Critique de la faculté de juger (1790). La typique serait un processus de symbolisation esthétique consistant à présenter, de façon indirecte, la représentation abstraite de la loi morale sous la forme d’un symbole concret et intuitif. Dans un premier chapitre, cette interprétation est présentée et soumise à un examen critique qui cherche à montrer qu’elle est erronée et peu judicieuse. Dans le second chapitre, nous poursuivons une voie d’interprétation jusqu’ici ignorée, montrant que la typique a de plus grandes continuités avec la notion d’« anthropomorphisme symbolique », une procédure strictement analogique introduite auparavant dans les Prolégomènes (1783). Nous en concluons, d’une part, que la typique fut un moment décisif dans l’évolution de la théorie kantienne de la représentation symbolique et que, d’autre part, elle marque la réalisation, chez Kant, d’une conception proprement critique de la nature et de la morale comme deux sphères distinctes, dont la médiation s’opère par le biais des concepts de loi et de conformité à la loi (Gesetzmässigkeit). En un mot, la typique s’avère l’instrument par excellence du « rationalisme de la faculté de juger ».

An analytical study of the power distribution pattterns of silica waveguides with high paraboloic cylindrical deformation

An attempt is made to determine the relative power distribution in a step-index parabolic cylindrical waveguide (PCW) with high deformation across the direction of propagation. The guide is assumed to be made of silica. The scalar field approximation is employed for the analysis under which a vanishing refractive-index (RI) difference in the waveguide materials is considered. Further, no approximation for folds- is used in the analytical treatment. Due to the geometry of such waceguides, PCWs lose the well-defined modal discreteness, and a kind of mode bunching is observed instead, which becomes much more prominent in PCWs with high bends. However, with the increase in cross-sectional size, the mode-bunching tendency is slightly reduced. The general expressions for power in the guiding and nonguiding sections are obtained, and the fractional power patterns in all of the sections are presented for PCWs of various cross-sectional dimensions. It is observed that the confinement of power in the core section is increased for PCWs of larger cross-sectional size. Moreover, a fairly uniform distribution of power is seen over the modes having intermediate values of propagation constants

Judicial Review of Academic Decisions

This thesis entitled “Judicial review of academic decisions.Education in India is being increasingly controlled and guided by the courts.This study makes an attempt to assess the involvement of the court in regulating education and its role or interference in the conventional concepts of ‘academic freedom’ and ‘university autonomy.The study mostly concentrates on the jurisdiction under Article 226 of the Constitution and its invocation in academic matters with particular reference to the decisions of the Kerala High Court.The concept of judicial review in the Constituent Assembly, initial approach of the Supreme Court of India towards the doctrine, gradual empowerment of Indian judiciary in this area and the resultant judicial activism.The study proceeds through the analysis of ‘academic freedom’ and ‘university autonomy’ in the 4"‘ chapter. This chapter attempts to probe academic freedom and university autonomy in India,England and United States and autonomy of Indian universities before and after independence.Basic principles and the jurisdictional parameters of judicial review in the area of academic decisions, as pronounced by the Apex Court, can be convincingly and consistently followed by the High Courts, which is possible only if special Academic Benches are constituted.

Short-Term Load Forecast Of A Low Loadfactor Power System For Optimization Of Merit Order Dispatch Using Adaptive Learning Algorithm

Short term load forecasting is one of the key inputs to optimize the management of power system. Almost 60-65% of revenue expenditure of a distribution company is against power purchase. Cost of power depends on source of power. Hence any optimization strategy involves optimization in scheduling power from various sources. As the scheduling involves many technical and commercial considerations and constraints, the efficiency in scheduling depends on the accuracy of load forecast. Load forecasting is a topic much visited in research world and a number of papers using different techniques are already presented. The accuracy of forecast for the purpose of merit order dispatch decisions depends on the extent of the permissible variation in generation limits. For a system with low load factor, the peak and the off peak trough are prominent and the forecast should be able to identify these points to more accuracy rather than minimizing the error in the energy content. In this paper an attempt is made to apply Artificial Neural Network (ANN) with supervised learning based approach to make short term load forecasting for a power system with comparatively low load factor. Such power systems are usual in tropical areas with concentrated rainy season for a considerable period of the year

Changing dynamics of the interinstitutional relationships between executive and legislature power in Colombia (2002/2006)

This paper describes the relationship between the executive and legislative branches during the first government of Alvaro Uribe Vélez. We will focus on reviewing the legislative output of each branch of power, along with the effectiveness and efficiency they showed as promoters of this production. We will review the impact they had on the legislative agenda setting and on the control of the legislative process  itself, making a diachronic analysis in which each legislature is used as a unit. Thus, we will try to identify the presence (or not) of some kind of pattern interactions,  and we will evaluate, at one hand, the existence of hierarchical and transactional trends, and, on the other, the different types of balances produced  between them.

Towards a Theoretical Understating of How to Study the State: Governmentality, Power and Governmental Regimes

Artículo teórico que se origina a partir de un proyecto más amplio que investiga la construcción del Plan Nacional del Buen Vivir 2013-2017 (PNBV 2013-2017) en Ecuador. Su primordial preocupación teórica es responder a la siguiente pregunta: cómo estudiar los procesos de formación del Estado en Ecuador desde el año 2008. El documento responde a esta amplia cuestión argumentando, a nivel general, que el Estado se reproduce en parte mediante la creación de espacios donde efectivamente puede intervenir en la sociedad. Este trabajo se refiere, por lo tanto, con el examen de las formas particulares en que los Estados penetran la sociedad a través de regímenes gubernamentales. En términos más específicos, este trabajo sostiene que los procesos de intervención del Estado pueden ser ampliamente entendidos por la observación de tres procesos complementarios e interrelacionados: a. La forma en la que el Estado busca legitimar su presencia en la sociedad; b. Prácticas gubernamentales: las formas en las que el Estado aprende, organiza, distribuye y en última instancia crea campos específicos de intervención; c. El ejercicio de diferentes y complementarias modalidades de poder. En base a los citados elementos analiza la construcción de un "régimen gubernamental".
