Theoretical perspectives of enterprise architecture

The number of published Enterprise Architecture (EA) research has increased during the last few years. As a discipline, EA is still young and lacking theoretical foundation. Lately some research trying to ground EA to theory has been published, including linkage to systems theory. Enterprise Architecture can be defined as; (i) a formal description of the current and future state(s) of an organisation, and (ii) a managed change between these states to meet organisation’s stakeholders’ goals and to create value to the organisation. Based on this definition, this conceptual paper tries to shed light to theoretical underpinnings of EA from three theoretical perspectives; EA as a communication media, EA as an activity, and EA as an information technology system. Our conclusions are that; (i) EA can be categorised as a communication media and theoretically underpinned by ontology and semiotics, (ii) EA can be explained and theoretically underpinned by Activity Theory, and (iii) EA can be categorised as an information technology system and theoretically underpinned by General Systems Theory and Technology Acceptance Theory.

Educação ambiental e contexto escolar: questões para um programa de pesquisas

In this paper are systematized the discussions conducted by GDP "Research in EA and School Context", in VII EPEA, which have had, as its main axis, themes, authors and theoretical perspectives privileged in research presented at the event and declared themselves affiliated to this GDP. The dialogue with researches from previous meetings and other, aims to deepen the questions posed by the research group. The discussions allowed to identify themes and issues that present themselves as significant and challenging for research in EA in the school context, namely the conversion of schools into sustainable educational spaces; public-private partnerships, with great interest from companies and NGOs in school spaces, waving kits with educational materials produced for the school; lack of investment in public policies for teacher training in EA; tendency to an adherence to critical environmental education, without, however, have clear theoretical and methodological commitments under this option.

A comprehensive EA benefit realization model -- An exploratory study

Enterprise architecture (EA) management has be-come an intensively discussed approach to manage enterprise transformations. While there is a strong interest in EA frameworks and EA modeling, a lack of knowledge remains about the theoretical foundation of EA benefits. In this paper, we identify EA success factors and EA benefits through a literature review, and integrate these findings with the DeLone & McLean IS success model to propose a theoretical model explaining the realization of EA benefits. In addition, we con-ducted semi-structured interviews with EA experts for a preliminary validation and further exploration of the model. We see this model as a first step to gain insights in and start a discussion on the theory of EA benefit realization. In future research, we plan to empirically validate the proposed model.

Ninguém morre de fome em Portugal? pobreza e mobilidade social na obra de Eça de Queirós (1878 1888)

O propósito desta dissertação é apresentar uma análise da pobreza e da mobilidade social na obra de Eça de Queirós no período de 1878 a 1888. Para tanto, examinaremos os personagens pobres, refletindo sobre seu papel na diegese, sua construção no texto e sua influência na concepção artística do autor; sobre a subjacente visão de mundo que nelas se expressa; e, finalmente, confrontamo-las, enquadradas no que tem sido considerado estética realista-naturalista. Esta pesquisa justifica-se pela proposta de criação de um novo foco de análise dentro da crítica queirosiana: aquele voltado às personagens que se dedicam de modo específico ao trabalho, e, ao fazê-lo, revelar a perspectiva do romancista relativamente à sociedade e ao momento histórico. O estudo que fazemos de alguns estratos sociais pouco valorizados (o pessoal doméstico, por exemplo) é uma lacuna nos estudos queirosianos. Algumas das personagens que acompanhamos passam quase despercebidas nos romances. Com exceção de Juliana, de O primo Basílio, têm intervenção mínima na ação. Ainda assim têm uma caracterização bastante elaborada, mesmo que por vezes com poucos traços, e não deixam de compor uma visão mais alargada da sociedade portuguesa do século XIX, desmentindo a ideia ainda hoje corrente de que Eça teria posto nos seus livros apenas os extratos sociais privilegiados de seu tempo. Para além da designação tão vaga de crítico social, Eça testemunhou um processo de transformação de um mundo em ruínas, que já não podia mais ser o que sempre fora

Ecos da fé na alma e na obra de Eça de Queiróz:uma visão crítica da Igreja e da Religião Católicas no século XIX

Esta dissertação, inserida na linha de pesquisa de Política e Cultura, trata da visão crítica de Eça de Queiroz sobre a Igreja Católica, sobre o catolicismo popular e a relação Igreja-Estado em Portugal do século XIX. O trabalho aprofunda as idéias do autor estabelecidas no momento histórico do chamado movimento da Regeneração, na segunda metade do século, marcado por propostas de denúncias da decadência da sociedade e de mudanças e reformas modernizantes nas estruturas econômicas, sociais, políticas educacionais e culturais do país. Analisa questões relevantes ligadas à política da época como o liberalismo monárquico, a política do estado constitucional português, a política ultramontana do Vaticano e seus desdobramentos em Portugal, além do catolicismo institucionalizado nas práticas políticas e culturais. A partir de fontes primárias como os trabalhos jornalísticos do autor, publicados no Brasil e em Portugal, assim como cartas para seus amigos intelectuais da chamada Geração 70, aborda questões como o anticlericalismo, antijesuitismo, Padroado, regalismo e o projeto cultural português de secularização. Observando o extremo espírito perspicaz e sarcástico do autor, o trabalho conclui por entender o escritor como forte defensor de reformas nas práticas, discursos e preocupações da Igreja Católica de seu tempo, assim como voz exigente e consonante a outros intelectuais da época em prol de novo comprometimento e atuação dessa mesma Igreja. Por fim, estabelece o autor como um expoente entre a intelectualidade por ser protagonista de um movimento de renovação política e cultural, como catalisador da opinião pública de seu tempo, e acima de tudo, autor de uma obra de relevância literária e jornalística, capaz de impor-se como efetiva proposta inovadora para a modernidade portuguesa da época.

A coarse fish close season on canals. Paper in evidence to the review of fisheries policy and legislation. Paper number: EA-12

This paper gives the results of the Environment Agency's research into the canal close season to the Salmon and Freshwater Fisheries Review Group. It presents the findings of the research, explains why the research was undertaken and how it relates to the Agency's duties. The background for this report includes that angling representative bodies have long argued that the existing situation in which somecanals have a close season and others do not, is unsatisfactory.

Anticlericalismo em mutação: as três versões de O Crime do Padre Amaro (1875-1876-1880), de Eça de Queirós

A pesquisa visa estudar as três versões de O Crime do Padre Amaro (1875, 1876, 1880) pelo viés da religiosidade, do anticlericalismo, da política. Ao abrir a dissertação, apresentar-se-á um quadro sucinto do momento histórico em que a obra foi escrita. A obra de José Maria Eça de Queirós costuma ser dividida em três fases: o primeiro momento, dito romântico, das Prosas Bárbaras (1866-1867) e da primeira versão de O Crime do Padre Amaro (1875); o segundo momento, quando, atraído pelas teorias do realismo/naturalismo, escreve a segunda e a terceira versões do Crime do Padre Amaro (1876 e 1880) e o Primo Basílio (1878); e o terceiro, desligado de normas específicas, de O Mandarim (1880), A Relíquia (1887), Os Maias (1888), A ilustre casa de Ramires (Póstumo, 1900) e A cidade e as serras (Póstumo, 1901). A história literária de O Crime do Padre Amaro inicia-se em 1875, e continua em duas outras edições, de 1876 e 1880. O objetivo do nosso estudo, ao revisitar as três versões de O Crime do Padre Amaro, é sobretudo analisar o processo de criação queirosiano na obra em tela, para, deste modo, identificar os pontos vitais que levaram o nosso autor a reescrevê-la duas vezes. Nossa hipótese maior de discussão para o problema levantado tem a ver com as teorias do realismo-naturalismo e com o anticlericalismo de Eça

Beyond LibGuides: The Past, Present, and Future of Online Research Guides

© 2015, Jon C. Giullian and Ernest A. Zitser.The proliferation of research guides created using the LibGuides platform has triggered extensive discussion touting their benefits for everything from assessment, engagement, and marketing, to outreach and pedagogy. However, there is at present a relative paucity of critical reflection about the product’s place in the broader informational landscape. This article is an attempt to redress this lacuna. Relying primarily on examples from the field of Slavic, East European, and Eurasian studies, the authors briefly describe the evolution of online research guides; identify reasons for the proliferation of Springshare’s product in academic libraries; question whether LibGuides improve learning or reinforce information inequality in higher education; and propose a way to move beyond LibGuides.

Towards groundwater security in coastal East Africa: initiating a regional research network and integrated hydrogeologic, climatic & socio-economic observatories in coastal aquifers of the Comoros Islands, Kenya and Tanzania

African coastal regions are expected to experience the highest rates of population growth in coming decades. Fresh groundwater resources in the coastal zone of East Africa (EA) are highly vulnerable to seawater intrusion. Increasing water demand is leading to unsustainable and ill-planned well drilling and abstraction. Wells supplying domestic, industrial and agricultural needs are or have become, in many areas, too saline for use. Climate change, including weather changes and sea level rise, is expected to exacerbate this problem. The multiplicity of physical, demographic and socio-economic driving factors makes this a very challenging issue for management. At present the state and probable evolution of coastal aquifers in EA are not well documented. The UPGro project 'Towards groundwater security in coastal East Africa' brings together teams from Kenya, Tanzania, Comoros Islands and Europe to address this knowledge gap. An integrative multidisciplinary approach, combining the expertise of hydrogeologists, hydrologists and social scientists, is investigating selected sites along the coastal zone in each country. Hydrogeologic observatories have been established in different geologic and climatic settings representative of the coastal EA region, where focussed research will identify the current status of groundwater and identify future threats based on projected demographic and climate change scenarios. Researchers are also engaging with end users as well as local community and stakeholder groups in each area in order to understanding the issues most affecting the communities and searching sustainable strategies for addressing these.

A realistic evaluation of track and trigger systems and acute care training for early recognition and treatment of deteriorating ward-based patients: research protocol.

Aim The aim of the study is to evaluate factors that enable or constrain the implementation and service delivery of early warnings systems or acute care training in practice. Background To date there is limited evidence to support the effectiveness of acute care initiatives (early warning systems, acute care training, outreach) in reducing the number of adverse events (cardiac arrest, death, unanticipated Intensive Care admission) through increased recognition and management of deteriorating ward based patients in hospital [1-3]. The reasons posited are that previous research primarily focused on measuring patient outcomes following the implementation of an intervention or programme without considering the social factors (the organisation, the people, external influences) which may have affected the process of implementation and hence measured end-points. Further research which considers the social processes is required in order to understand why a programme works, or does not work, in particular circumstances [4]. Method The design is a multiple case study approach of four general wards in two acute hospitals where Early Warning Systems (EWS) and Acute Life-threatening Events Recognition and Treatment (ALERT) course have been implemented. Various methods are being used to collect data about individual capacities, interpersonal relationships and institutional balance and infrastructures in order to understand the intended and unintended process outcomes of implementing EWS and ALERT in practice. This information will be gathered from individual and focus group interviews with key participants (ALERT facilitators, nursing and medical ALERT instructors, ward managers, doctors, ward nurses and health care assistants from each hospital); non-participant observation of ward organisation and structure; audit of patients' EWS charts and audit of the medical notes of patients who deteriorated during the study period to ascertain whether ALERT principles were followed. Discussion & progress to date This study commenced in January 2007. Ethical approval has been granted and data collection is ongoing with interviews being conducted with key stakeholders. The findings from this study will provide evidence for policy-makers to make informed decisions regarding the direction for strategic and service planning of acute care services to improve the level of care provided to acutely ill patients in hospital.

Genistein reverses changes of the proteome induced by oxidized-LDL in EA center dot hy 926 human endothelial cells

Endothelial cells are primary targets for pro-atherosclerotic stressors such as oxidized LDL (ox-LDL). The isoflavone genistein, on the other hand, is suggested to prevent a variety of processes underlying atherosclerosis and cardiovascular diseases. By analyzing the proteome of EA(.)hy 926 endothelial cells, here we show, that genistein reverses the ox-LDL-induced changes of the steady-state levels of several proteins involved in atherosclerosis. These alterations caused by genistein are functionally linked to the inhibition of ox-LDL induced apoptosis.

The art of shooting the moving goal - explorative study of EA pilot

Enterprise Architecture (EA) has been recognised as an important tool in modern business management for closing the gap between strategy and its execution. The current literature implies that for EA to be successful, it should have clearly defined goals. However, the goals of different stakeholders are found to be different, even contradictory. In our explorative research, we seek an answer to the questions: What kind of goals are set for the EA implementation? How do the goals evolve during the time? Are the goals different among stakeholders? How do they affect the success of EA? We analysed an EA pilot conducted among eleven Finnish Higher Education Institutions (HEIs) in 2011. The goals of the pilot were gathered from three different stages of the pilot: before the pilot, during the pilot, and after the pilot, by means of a project plan, interviews during the pilot and a questionnaire after the pilot. The data was analysed using qualitative and quantitative methods. Eight distinct goals were recognised by the coding: Adopt EA Method, Build Information Systems, Business Development, Improve Reporting, Process Improvement, Quality Assurance, Reduce Complexity, and Understand the Big Picture. The success of the pilot was analysed statistically using the scale 1-5. Results revealed that goals set before the pilot were very different from those mentioned during the pilot, or after the pilot. Goals before the pilot were mostly related to expected benefits from the pilot, whereas the most important result was to adopt the EA method. Results can be explained by possibly different roles of respondents, which in turn were most likely caused by poor communication. Interestingly, goals mentioned by different stakeholders were not limited to their traditional areas of responsibility. For example, in some cases Chief Information Officers' goals were Quality Assurance and Process Improvement, whereas managers’ goals were Build Information Systems and Adopt EA Method. This could be a result of a good understanding of the meaning of EA, or stakeholders do not regard EA as their concern at all. It is also interesting to notice that regardless of the different perceptions of goals among stakeholders, all HEIs felt the pilot to be successful. Thus the research does not provide support to confirm the link between clear goals and success.
