Interoperability frameworks for competencies and learning outcomes: databases vs ontologies

The changes introduced into the European Higher Education Area (EHEA) by the Bologna Process, together with renewed pedagogical and methodological practices, have created a new teaching-learning paradigm: Student-Centred Learning. In addition, the last few years have been characterized by the application of Information Technologies, especially the Semantic Web, not only to the teaching-learning process, but also to administrative processes within learning institutions. On one hand, the aim of this study was to present a model for identifying and classifying Competencies and Learning Outcomes and, on the other hand, the computer applications of the information management model were developed, namely a relational Database and an Ontology.

Desarrollo de frameworks con .NET

La expansión experimentada por la informática, las nuevas tecnologías e internet en los últimos años, no solo viene dada por la evolución del hardware subyacente, sino por la evolución del desarrollo de software y del crecimiento del número de desarrolladores. Este incremento ha hecho evolucionar el software de unos sistemas de gestión basados en ficheros, prácticamente sin interfaz gráfico y de unos pocos miles de líneas a grandes sistemas distribuidos multiplataforma. El desarrollo de estos grandes sistemas, requiere gran cantidad de personas involucradas en el desarrollo, y que las herramientas de desarrollo hayan crecido también para facilitar su análisis, diseño, codificación, pruebas, implantación y mantenimiento. La base de estas herramientas software las proveen las propias plataformas de desarrollo, pero la experiencia de los desarrolladores puede aportar un sinfín de utilidades y de técnicas que agilicen los desarrollos y cumplan los requisitos del software en base a la reutilización de soluciones lo suficientemente probadas y optimizadas. Dichas herramientas se agrupan ordenadamente, creando así frameworks personalizados, con herramientas de todo tipo, clases, controles, interfaces, patrones de diseño, de tal manera que se dan soluciones personalizadas a un amplio número de problemas para emplearlas cuantas veces se quiera, bien marcando directrices de desarrollo mediante el uso de patrones, bien con la encapsulación de complejidades de tal modo que los desarrolladores ya dispongan de componentes que asuman cierta lógica o cierta complejidad aliviando así la fase de construcción. En este trabajo se abordan temas sobre las tecnologías base y plataformas de desarrollo para poder acometer la creación de un framework personalizado, necesidades a evaluar antes de acometerlo, y técnicas a emplear para la consecución del mismo, orientadas a la documentación, mantenimiento y extensión del framework. La exposición teórica consiste en mostrar y evaluar los requisitos para crear un framework, requisitos de la plataforma de desarrollo, y explicar cómo funcionan las grandes plataformas de desarrollo actuales, que elementos los componen y su funcionamiento, así como marcar ciertas pautas de estructuración y nomenclatura que el desarrollo de un framework debe contemplar para su mantenimiento y extensión. En la parte metodológica se ha usado un subconjunto de Métrica V3, ya que para el desarrollo de controles no aplica dicha metodología en su totalidad, pero contempla el catálogo de requisitos, los casos de uso, diagramas de clase, diagramas de secuencia, etc… Aparte de los conceptos teóricos, se presenta un caso práctico con fines didácticos de cómo parametrizar y configurar el desarrollo bajo la plataforma .NET. Dicho caso práctico consiste en la extensión de un control de usuario genérico de la plataforma .NET, de tal modo que se aplican conceptos más allá del hecho de crear funciones como las funcionalidades que puede brindar un API. Conceptos sobre como extender y modificar controles ya existentes, que interactúan por medio de eventos con otros controles, con vistas a que ese nuevo control forme parte de una biblioteca de controles de usuario personalizados ampliamente divulgada. Los controles de usuario son algo que no solo tienen una parte funcional, sino que también tienen una parte visual, y definiciones funcionales distintas de las típicas del software de gestión, puesto que han de controlar eventos, visualizaciones mientras se dan estos eventos y requisitos no funcionales de optimización de rendimiento, etc… Para el caso práctico se toma como herramienta la plataforma de desarrollo .Net Framework, en todas sus versiones, ya que el control a extender es el control ListView y hacerlo editable. Este control está presente en todas las versiones de .NET framework y con un alto grado de reutilización. Esta extensión muestra además como se puede migrar fácilmente este tipo de extensiones sobre todos los frameworks. Los entornos de desarrollo usados son varias versiones de Visual Studio para el mostrar dicha compatibilidad, aunque el desarrollo que acompaña este documento esté realizado sobre Visual Studio 2013. ABSTRACT The expansion in computer science, new technologies and the Internet in recent years, not only is given by the evolution of the underlying hardware, but for the evolution of software development and the growing number of developers. This increase has evolved software from management systems based on files almost without graphical interface and a few thousand of code lines, to large multiplatform distributed systems. The development of these large systems, require lots of people involved in development, and development tools have also grown to facilitate analysis, design, coding, testing, deployment and maintenance. The basis of these software tools are providing by their own development platforms, but the experience of the developers can bring a lot of utilities and techniques to speed up developments and meet the requirements of software reuse based on sufficiently proven solutions and optimized. These tools are grouped neatly, creating in this way custom frameworks, with tools of all types, classes, controls, interfaces, design patterns,… in such a way that they provide customized solutions to a wide range of problems to use them many times as you want to occur, either by dialing development guidelines by using patterns or along with the encapsulation of complexities, so that developers already have components that take some logic or some complexity relieving the construction phase. This paper cover matters based on technologies and development platforms to undertake the creation of a custom framework, needs to evaluate before rush it and techniques to use in order to achieve it, a part from techniques oriented to documentation, maintenance and framework extension. The theoretical explanation consists in to demonstrate and to evaluate the requirements for creating a framework, development platform requirements, and explain how large current development platforms work, which elements compose them and their operation work, as well as mark certain patterns of structure and nomenclature that the development of a framework should include for its maintenance and extension. In the methodological part, a subset of Métrica V3 has been used, because of, for the development of custom controls this methodology does not apply in its entirety, but provides a catalogue of requirements, use cases, class diagrams, sequence diagrams, etc ... Apart from the theoretical concepts, a study case for teaching purposes about how to parameterize and configure the development under the .NET platform is presented. This study case involves the extension of a generic user control of the .NET platform, so that concepts apply beyond the fact of creating functions as the functionalities that can provide an API. Concepts on how to extend and modify existing controls that interact through events with other controls, overlooking that new control as a part of a custom user controls library widely publicized. User controls are something that not only have a functional part, but also have a visual part, and various functional definitions of typical management software, since that they have to control events, visualizations while these events are given and not functional of performance optimization requirements, etc ... For the study case the development platform .Net Framework is taken as tool, in all its versions, considering that control to extend is the ListView control and make it editable. This control is present in all versions of .NET framework and with a high degree of reuse. This extension also shows how you can easily migrate these extensions on all frameworks. The used development environments are several versions of Visual Studio to show that compatibility, although the development that accompanies this document is done on Visual Studio 2013.

The “social” aspect of social-ecological systems: a critique of analytical frameworks and findings from a multisite study of coastal sustainability

We evaluate whether society can adequately be conceptualized as a component of social-ecological systems, given social theory and the current outputs of systems-based research. A mounting critique from the social sciences posits that resilience theory has undertheorized social entities with the concept of social-ecological systems. We trace the way that use of the term has evolved, relating to social science theory. Scientometic and network analysis provide a wide range of empirical data about the origin, growth, and use of this term in academic literature. A content analysis of papers in Ecology and Society demonstrates a marked emphasis in research on institutions, economic incentives, land use, population, social networks, and social learning. These findings are supported by a review of systems science in 18 coastal assessments. This reveals that a systems-based conceptualization tends to limit the kinds of social science research favoring quantitative couplings of social and ecological components and downplaying interpretive traditions of social research. However, the concept of social-ecological systems remains relevant because of the central insights concerning the dynamic coupling between humans and the environment, and its salient critique about the need for multidisciplinary approaches to solve real world problems, drawing on heuristic devices. The findings of this study should lead to more circumspection about whether a systems approach warrants such claims to comprehensiveness. Further methodological advances are required for interdisciplinarity. Yet there is evidence that systems approaches remain highly productive and useful for considering certain social components such as land use and hybrid ecological networks. We clarify advantages and restrictions of utilizing such a concept, and propose a reformulation that supports engagement with wider traditions of research in the social sciences.

Likelihood-maximising frameworks for enhanced in-car speech recognition

Speech recognition in car environments has been identified as a valuable means for reducing driver distraction when operating non-critical in-car systems. Likelihood-maximising (LIMA) frameworks optimise speech enhancement algorithms based on recognised state sequences rather than traditional signal-level criteria such as maximising signal-to-noise ratio. Previously presented LIMA frameworks require calibration utterances to generate optimised enhancement parameters which are used for all subsequent utterances. Sub-optimal recognition performance occurs in noise conditions which are significantly different from that present during the calibration session - a serious problem in rapidly changing noise environments. We propose a dialog-based design which allows regular optimisation iterations in order to track the changing noise conditions. Experiments using Mel-filterbank spectral subtraction are performed to determine the optimisation requirements for vehicular environments and show that minimal optimisation assists real-time operation with improved speech recognition accuracy. It is also shown that the proposed design is able to provide improved recognition performance over frameworks incorporating a calibration session.

Gender and the Australian parliament

This dissertation by publication which focuses on gender and the Australian federal parliament has resulted in the submission of three refereed journal articles. Data for the study were obtained from 30 semi-structured interviews undertaken in 2006 with fifteen (15) male and fifteen (15) female members of the Australian parliament. The first of the articles is methodological and has been accepted for publication in the Australian Journal of Political Science. The paper argues that feminist political science is guided by five important principles. These are placing gender at the centre of the research, giving emphasis to women’s voice, challenging the public/private divide, using research to transform society and taking a reflexive approach to positionality. It is the latter principle, that of the importance of taking a reflexive approach to research which I explore in the paper. Through drawing on my own experiences as a member of the House of Representatives (Forde 1987-1996) I reflexively investigate the intersections between my background and my identity as a researcher. The second of the articles views the data through the lens of Acker’s (1990) notion of the ‘gendered organization’ which posits that there are four dimensions by which organizations are gendered. These are via the division of labour, through symbols, images and ideologies, by workplace interactions and through the gendered components of individual identity. In this paper which has been submitted to the British Journal of Political Science, each of Acker’s (1990) dimensions is examined in terms of the data from interviews with male and female politicians. The central question investigated is thus to what extent does the Australian parliament conform to Acker’s (1990) concept of the ‘gendered organization’? The third of the papers focuses specifically on data from interviews with the 15 male politicians and investigates how they view gender equality and the Australian parliament. The article, which has been submitted to the European Journal of Political Science asks to what extent contemporary male politicians view the Australian parliament as gendered? Discourse analysis that is ‘ways of viewing’ (Bacchi, 1999, p. 40) is used as an approach to analyse the data. Three discursive frameworks by which male politicians view gender in the Australian parliament are identified. These are: that the parliament is gendered as masculine but this is unavoidable; that the parliament is gendered as feminine and women are actually advantaged; and that the parliament is gender neutral and gender is irrelevant. It is argued that collectively these framing devices operate to mask the many constraints which exist to marginalise women from political participation and undermine attempts to address women’s political disadvantage as political participants. The article concludes by highlighting the significance of the paper beyond the Australian context and calling for further research which names and critiques political men and their discourses on gender and parliamentary practices and processes.

Using ontology for the representational analysis of process modelling techniques

Selecting an appropriate business process modelling technique forms an important task within the methodological challenges of a business process management project. While a plethora of available techniques has been developed over the last decades, there is an obvious shortage of well-accepted reference frameworks that can be used to evaluate and compare the capabilities of the different techniques. Academic progress has been made at least in the area of representational analyses that use ontology as a benchmark for such evaluations. This paper reflects on the comprehensive experiences with the application of a model based on the Bunge ontology in this context. A brief overview of the underlying research model characterizes the different steps in such a research project. A comparative summary of previous representational analyses of process modelling techniques over time gives insights into the relative maturity of selected process modelling techniques. Based on these experiences suggestions are made as to where ontology-based representational analyses could be further developed and what limitations are inherent to such analyses.

Universities, SMEs and innovation frameworks : think global, act local?

Universities are increasingly encouraged to take a leading role in economic development, particularly through innovation. Simultaneously, economic development policy itself is increasingly focused on small and medium-sized enterprises (SMEs), creating overlapping interactions in the roles of government policy, universities and SMEs and the processes of innovation creation and dissemination. This paper examines issues arising from these developments and relating to the key stakeholders (industry, government and universities in particular), the enabling mechanisms (network governance, relevant education, training and learning, and suitable structures), and local and cross-local links. The authors then use quantitative analysis of 450 SMEs in the UK to begin to evaluate the roles of universities and highlight areas for further theoretical development.

Formative and reflective measurement and validation mismatch in survey research : an archival analysis of information systems success constructs 1985-2007

The generic IS-success constructs first identified by DeLone and McLean (1992) continue to be widely employed in research. Yet, recent work by Petter et al (2007) has cast doubt on the validity of many mainstream constructs employed in IS research over the past 3 decades; critiquing the almost universal conceptualization and validation of these constructs as reflective when in many studies the measures appear to have been implicitly operationalized as formative. Cited examples of proper specification of the Delone and McLean constructs are few, particularly in light of their extensive employment in IS research. This paper introduces a four-stage formative construct development framework: Conceive > Operationalize > Respond > Validate (CORV). Employing the CORV framework in an archival analysis of research published in top outlets 1985-2007, the paper explores the extent of possible problems with past IS research due to potential misspecification of the four application-related success dimensions: Individual-Impact, Organizational-Impact, System-Quality and Information-Quality. Results suggest major concerns where there is a mismatch of the Respond and Validate stages. A general dearth of attention to the Operationalize and Respond stages in methodological writings is also observed.

High Culture as Subculture : Brisbane's Contemporary Chamber Music Scene

The aim of the dissertation is to discover the extent to which methodologies and conceptual frameworks used to understand popular culture may also be useful in the attempt to understand contemporary high culture. The dissertation addresses this question through the application of subculture theory to Brisbane’s contemporary chamber music scene, drawing on a detailed case study of the contemporary chamber ensemble Topology and its audiences. The dissertation begins by establishing the logic and necessity of applying cultural studies methodologies to contemporary high culture. This argument is supported by a discussion of the conceptual relationships between cultural studies, high culture, and popular culture, and the methodological consequences of these relationships. In Chapter 2, a brief overview of interdisciplinary approaches to music reveals the central importance of subculture theory, and a detailed survey of the history of cultural studies research into music subcultures follows. Five investigative themes are identified as being crucial to all forms of contemporary subculture theory: the symbolic; the spatial; the social; the temporal; the ideological and political. Chapters 3 and 4 present the findings of the case study as they relate to these five investigative themes of contemporary subculture theory. Chapter 5 synthesises the findings of the previous two chapters, and argues that while participation in contemporary chamber music is not as intense or pervasive as is the case with the most researched street-based youth subcultures, it is nevertheless possible to describe Brisbane’s contemporary chamber music scene as a subculture. The dissertation closes by reflecting on the ways in which the subcultural analysis of contemporary chamber music has yielded some insight into the lived practices of high culture in contemporary urban contexts.

Frameworks in regulating company directors : rethinking the philosophical foundations to enhance accountability

Sets out a system of corporate governance regulation, aimed at combining legal and social methods of governing director behaviour and at creating a framework flexible enough to accommodate different business and ethical cultures. Outlines the theoretical basis of corporate governance and the broad responsibilities of directors, and discusses the extent to which they can and should be regulated. Discusses the constitution of a regulatory framework encompassing law, soft law and best practice, and ethics.
