Cross organisational compatible workflows generation and execution

With the development of internet and electronics, the demand for electronic and online commerce has increased. This has, in turn, increased the demand for business process automation. Workflow has established itself as the technology used for business process automation. Since business organisations have to work in coordination with many other business organisations in order to succeed in business, the workflows of business organisations are expected to collaborate with those of other business organisations. Collaborating organisations can only proceed in business if they have compatible workflows. Therefore, there is a need for cross organisational workflow collaboration. The dynamism and complexity of online and electronic business and high demand from the market leave the workflows prone to frequent changes. If a workflow changes, it has to be re-engineered as well as reconciled with the workflows of the collaborating organisations. To avoid the continuous re-engineering and reconciliation of workflows, and to reuse the existing units of work done, the focus has recently shifted from modeling workflows to automatic workflow generation. Workflows must proceed to runtime execution, otherwise, the effort invested in the build time workflow modeling is wasted. Therefore, workflow management and collaboration systems must support workflow enactment and runtime workflow collaboration. Although substantial research has been done in build-time workflow collaboration, automatic workflow generation, workflow enactment and runtime workflow collaboration, the integration of these highly inter-dependent aspects of workflow has not been considered in the literature. The research work presented in this thesis investigates the integration of these different aspects. The main focus of the research presented in this thesis is the creation of a framework that is able to generate multiple sets of compatible workflows for multiple collaborating organisations, from their OWLS process definitions and high level goals. The proposed framework also supports runtime enactment and runtime collaboration of the generated workflows

Trust in “Trust-free” Digital Networks: How Inter-firm Algorithmic Relationships Embed the Cardinal Principles of Value Co-creation

In this exploratory research, I develop new knowledge on trust in inter-firm cooperation that leverages recent technologies such as blockchain and the Internet of things in a digital platform ecosystem. In a digital network, advanced algorithms govern and shape inter-firm business processes. While such algorithms introduce efficiency in inter-firm business processes, their limitations, especially their apparent lack of transparency, may affect the key trust dimensions (i.e., reliability, fairness, and goodwill) in the relationships among the participating firms. I introduce algorithmic relationship, a label that embeds the concepts of smart contracts in inter-firm cooperation. Algorithmic relationships involve autonomous and semi-autonomous implementations of smart contracts in all lifecycle stages of inter-firm cooperation. By analyzing extant literature on trust, inter-firm cooperation, business model innovation, and digital platforms, I demonstrate how various factors influence whether firms adopt smart contracts: perceptions about other participants’ trustworthiness, participants’ own propensity to trust, participants’ shared goals and resource embeddedness in the network, perceived risks in inter-firm interactions, and complexity and time criticality of inter-firm interactions. Taking a temporal perspective, I also recognize the present lacunae with smart contracts from various perspectives (algorithm development, algorithm implementation, algorithm governance, and the availability of appropriate legal resources in the event that disputes occur) and demonstrate how these drawbacks impede shared value creation

Harmonize: a shared environment for extended immersive entertainment

Virtual reality (VR) and augmented reality (AR) applications are very diffuse nowadays. Moreover, recent technology innovations led to the diffusion of commercial head-mounted displays (HMDs) for immersive VR: users can enjoy entertainment activities that fill their visual fields, experiencing the sensation of physical presence in these virtual immersive environments (IEs). Even if AR and VR are mostly used separately, they can be effectively combined to provide a multi-user shared environment (SE), where two or more users perform some specific tasks in a cooperative or competitive way, providing a wider set of interactions and use cases compared to immersive VR alone. However, due to the differences between the two technologies, it is difficult to develop SEs offering a similar experience for both AR and VR users. This paper presents Harmonize, a novel framework to deploy applications based on SEs with a comparable experience for both AR and VR users. Moreover, the framework is hardware-independent and it has been designed to be as much extendable to novel hardware as possible. An immersive game has been designed to test and to evaluate the validity of the proposed framework. The assessment of the system through the System Usability Scale (SUS) questionnaire and the Game Experience Questionnaire (GEQ) shows a positive evaluation

Ontology Localization

Nuestra meta principal en esta tesis es proponer una solución para construir una ontología multilingüe, a través de la localización automática de una ontología. La noción de localización viene del área de Desarrollo de Software que hace referencia a la adaptación de un producto de software a un ambiente no nativo. En la Ingeniería Ontológica, la localización de ontologías podría ser considerada como un subtipo de la localización de software en el cual el producto es un modelo compartido de un dominio particular, por ejemplo, una ontología, a ser usada por una cierta aplicación. En concreto, nuestro trabajo introduce una nueva propuesta para el problema de multilingüismo, describiendo los métodos, técnicas y herramientas para la localización de recursos ontológicos y cómo el multilingüismo puede ser representado en las ontologías. No es la meta de este trabajo apoyar una única propuesta para la localización de ontologías, sino más bien mostrar la variedad de métodos y técnicas que pueden ser readaptadas de otras áreas de conocimiento para reducir el costo y esfuerzo que significa enriquecer una ontología con información multilingüe. Estamos convencidos de que no hay un único método para la localización de ontologías. Sin embargo, nos concentramos en soluciones automáticas para la localización de estos recursos. La propuesta presentada en esta tesis provee una cobertura global de la actividad de localización para los profesionales ontológicos. En particular, este trabajo ofrece una explicación formal de nuestro proceso general de localización, definiendo las entradas, salidas, y los principales pasos identificados. Además, en la propuesta consideramos algunas dimensiones para localizar una ontología. Estas dimensiones nos permiten establecer una clasificación de técnicas de traducción basadas en métodos tomados de la disciplina de traducción por máquina. Para facilitar el análisis de estas técnicas de traducción, introducimos una estructura de evaluación que cubre sus aspectos principales. Finalmente, ofrecemos una vista intuitiva de todo el ciclo de vida de la localización de ontologías y esbozamos nuestro acercamiento para la definición de una arquitectura de sistema que soporte esta actividad. El modelo propuesto comprende los componentes del sistema, las propiedades visibles de esos componentes, las relaciones entre ellos, y provee además, una base desde la cual sistemas de localización de ontologías pueden ser desarrollados. Las principales contribuciones de este trabajo se resumen como sigue: - Una caracterización y definición de los problemas de localización de ontologías, basado en problemas encontrados en áreas relacionadas. La caracterización propuesta tiene en cuenta tres problemas diferentes de la localización: traducción, gestión de la información, y representación de la información multilingüe. - Una metodología prescriptiva para soportar la actividad de localización de ontologías, basada en las metodologías de localización usadas en Ingeniería del Software e Ingeniería del Conocimiento, tan general como es posible, tal que ésta pueda cubrir un amplio rango de escenarios. - Una clasificación de las técnicas de localización de ontologías, que puede servir para comparar (analíticamente) diferentes sistemas de localización de ontologías, así como también para diseñar nuevos sistemas, tomando ventaja de las soluciones del estado del arte. - Un método integrado para construir sistemas de localización de ontologías en un entorno distribuido y colaborativo, que tenga en cuenta los métodos y técnicas más apropiadas, dependiendo de: i) el dominio de la ontología a ser localizada, y ii) la cantidad de información lingüística requerida para la ontología final. - Un componente modular para soportar el almacenamiento de la información multilingüe asociada a cada término de la ontología. Nuestra propuesta sigue la tendencia actual en la integración de la información multilingüe en las ontologías que sugiere que el conocimiento de la ontología y la información lingüística (multilingüe) estén separados y sean independientes. - Un modelo basado en flujos de trabajo colaborativos para la representación del proceso normalmente seguido en diferentes organizaciones, para coordinar la actividad de localización en diferentes lenguajes naturales. - Una infraestructura integrada implementada dentro del NeOn Toolkit por medio de un conjunto de plug-ins y extensiones que soporten el proceso colaborativo de localización de ontologías

Semantic technologies: from niche to the mainstream of Web 3? A comprehensive framework for web Information modelling and semantic annotation

Context: Web information technologies developed and applied in the last decade have considerably changed the way web applications operate and have revolutionised information management and knowledge discovery. Social technologies, user-generated classification schemes and formal semantics have a far-reaching sphere of influence. They promote collective intelligence, support interoperability, enhance sustainability and instigate innovation. Contribution: The research carried out and consequent publications follow the various paradigms of semantic technologies, assess each approach, evaluate its efficiency, identify the challenges involved and propose a comprehensive framework for web information modelling and semantic annotation, which is the thesis’ original contribution to knowledge. The proposed framework assists web information modelling, facilitates semantic annotation and information retrieval, enables system interoperability and enhances information quality. Implications: Semantic technologies coupled with social media and end-user involvement can instigate innovative influence with wide organisational implications that can benefit a considerable range of industries. The scalable and sustainable business models of social computing and the collective intelligence of organisational social media can be resourcefully paired with internal research and knowledge from interoperable information repositories, back-end databases and legacy systems. Semantified information assets can free human resources so that they can be used to better serve business development, support innovation and increase productivity

Increasing Collective Teacher Efficacy through Inuit Qaujimajatuqangit and Coaching: A Community-Based Approach

Abstract Instructional coaching in one remote northern community focuses on teacher mentorship and professional learning and prioritizes the implementation of prepackaged literacy resources. This focus on the implementation of prepackaged programs and data collection, promotes neo-liberal priorities and the privatization of education, over the methods that support the inclusion of Inuit cultural knowledge. Kostogriz (2011) states that we should be cautious about accepting the neo-liberal discourse of the literacy crisis and standardized reforms, the author suggests that low levels of literacy are not a large-scale problem so much as a result of under-provision of a socially just education. This Problem of Practice investigates the role of the learning coach in increasing collective teacher efficacy in accordance with the principals of Inuit Qaujimajatuqangit (IQ). Coaching to improve collective teacher efficacy through the integration of IQ may show greater educational improvement than literacy coaching alone. This vision for change includes an analysis coaching philosophy, leading from the middle, critical theory, organizational learning, the practice of decolonizing education and the positive effects of improving collective teacher efficacy. A PESTE analysis of the political, socio-economic factors; Bolman and Deal’s (2008) human resource frame and Nadler and Tushman’s (1980) congruence model will guide the critical organizational analysis. The leadership approaches to change are transformational, transformative and include ethical and decolonizing methods. The Change Path Model of Cawsey, Deszca, and Ingols (2016) is the chosen organizational framework for leading change in this Organizational Improvement Plan. Analysis of relevant internal data presents information on student educational attainment levels, and external data describes the positive effects of increasing collective efficacy on student achievement and school improvement. Hall and Hord’s (2006) six functions guide the coaching process and Change Path Model implementation planning (Cawsey et al., (2016). Implementation is presented through a series of Plan Do Study Act cycles and supported with a plan to communicate change (Conzemius & O’Neill, 2014). Coaching to influence teacher collaboration with a greater emphasis on IQ approaches and knowledge is seen as a key pathway in the leadership model to increase collective efficacy beliefs.

Engagement through Emancipation, Empowerment, and Equity: Heutagogy and the 21st-Century Classroom

Low student engagement has become a problem for Engagement Academy (a pseudonym), as well as for most schools in Newfoundland and Labrador. Data indicates that approximately 70% of graduating students are disengaged and feel their educational experience is not adequately preparing them for life in the 21st-century. Issues related to student engagement reflect the failure of the province’s school system to adapt to societal trends and remain relevant in the 21st-century. Although a 21st-century workforce values competencies such as creativity, critical-thinking, and collaboration, traditional school systems value and reward compliance and conformity. Worse, a critical examination of traditional education systems reveals that many school structures preserve and perpetuate systemic inequities that harm its most marginalized students. This organizational improvement plan employs a humanistic lens that draws upon instructional, transformational, servant, and distributed leadership models that emancipate students from the oppressive structures of traditional schools. The implementation of classroom practices based on heutagogy and the adoption of the pedagogy-andragogy-heutagogy continuum is presented as a strategy to engage Grade 7–9 students in a 21st-century educational environment. Kotter’s eight-step model for organizational change and cycles of collaborative inquiry guides teachers through the change process. The concerns-based adoption model provides a framework for developing the change vision, identifying resistance factors, and monitoring change implementation. Klein’s communication model and Lewis’s stakeholder communication help to create a communication plan for the OIP

Words In Action: Interdisciplinary Approaches To Understanding Word Processing And Storage

Almost all levels of language knowledge and processing (from phonology, to syntax and semantics) are known to be affected by knowledge of word structure at varying degrees. A better understanding of the human strategies involved in learning and processing word structure thus lies at the heart of our comprehension of the basic mechanisms serving both language and cognition and is key to addressing some fundamental challenges for the study of the physiology of grammar. On the 12th and 13th of October 2009, in the Research Area of the Italian National Research Council (CNR) in Pisa, 26 scholars from Europe, Canada and the United States were convened to take part in the European Science Foundation Exploratory Workshop "Words in Action: Interdisciplinary Approaches To Understanding Word Processing And Storage". The workshop brought together experts of various scientific domains and different theoretical inclinations to advance the current awareness of theoretical, historical, psycholinguistic, computational and neurophysiological issues in morphological processing and learning, with a view to assessing levels of research convergence and exploring the potential for synergy and strategic co-operation
