    Get PDF
    Num contexto de globalização, os mercados externos apresentam-se, cada vez mais, como imprescindíveis à sobrevivência das empresas. Com efeito, as oportunidades e ameaças que a globalização envolve são determinantes para que as empresas procurem novas formas de manter e aumentar o seu desempenho e sustentabilidade. A internacionalização assume, por isso, primordial importância para a competitividade das mesmas. Este processo envolve a definição de estratégias operacionais que resultarão em importantes fluxos financeiros, de produtos e de conhecimento para as organizações. Em Portugal e, após a recente crise económica, o tema da internacionalização, sobretudo para as Pequenas e Médias Empresas (PME), tornou-se fundamental para a sua sustentabilidade. O processo de internacionalização é incremental para a grande maioria das empresas portuguesas. O investimento externo surge como efeito de uma experiência de exportação. Considerando que um processo de internacionalização é um processo complexo, envolvendo riscos elevados, o objetivo deste trabalho será estudar o processo de internacionalização de duas empresas portuguesas e uma ibérica. Seguindo uma metodologia qualitativa, assente no estudo de caso, pretende-se perceber o porquê e como decorreu o seu processo de internacionalização, seus objetivos e estratégias envolvidas. Dado que, ao analisar o processo de internacionalização de uma empresa, é importante confrontar modelos teóricos com a prática empresarial, procuraremos confrontar e verificar a validade das teorias e literatura relevantes com os casos em análise. De acordo com os resultados obtidos foi possível concluir que não existe, para as empresas em estudo, um modo de entrada único, existindo recurso à utilização de múltiplos modos de entrada, identificável com o modelo não sequencial. A vontade de crescimento revelou-se como a motivação em comum e mais referida pelas empresas, assim como as barreiras culturais para os principais entraves à internacionalização. Ambas as empresas recorrem a apoios externos, mas com diferentes finalidades e as mesmas revelaram-se ainda ricas na variedade de informações a que nos foi dado acesso.In a context of globalization, external markets are becoming more and more indispensable to the survival of companies. Indeed, the opportunities and threats that globalization entails are crucial for companies to seek new ways to maintain and increase their performance and sustainability. Internationalization is therefore of prime importance for their competitiveness. This process involves the definition of operational strategies that will result in important financial, product and knowledge flows for organizations. In Portugal, and after the recent economic crisis, the theme of internationalization, especially for Small and Medium Enterprises (SMEs), has become fundamental for its sustainability. The internationalization process is incremental for the great majority of Portuguese companies. External investment is the result of an export experience. Considering that an internationalization process is a complex process, involving high risks, the aim of this work will be to study the internationalization process of two Portuguese companies and one Iberian. Following a qualitative methodology, based on case study, we intend to understand why and how its internationalization process occurred, its goals and the strategies involved. Given that, when analyzing the process of internationalization of a company, it is important to confront theoretical models with business practice, we will try to confront and verify the validity of relevant theories and literature with the cases under analysis. According to the results obtained, it was possible to conclude that for the companies under study there is no single input mode, and there is a use of multiple input modes, identifiable with the non-sequential model. The will to growth has proved to be the common motivation and more mentioned by the companies, as well as the cultural barriers to the main obstacles to internationalization. Both companies rely on external support, but for different purposes and they have proved rich in the variety of information to which we have been granted access

    © 2017, Springer-Verlag Berlin Heidelberg. In tweet authentication, we are concerned with correctly attributing a tweet to its true author based on its textual content. The more general problem of authenticating long documents has been studied before and the most common approach relies on the intuitive idea that each author has a unique style that can be captured using stylometric features (SF). Inspired by the success of modern automatic document classification problem, some researchers followed the Bag-Of-Words (BOW) approach for authenticating long documents. In this work, we consider both approaches and their application on authenticating tweets, which represent additional challenges due to the limitation in their sizes. We focus on the Arabic language due to its importance and the scarcity of works related on it. We create different sets of features from both approaches and compare the performance of different classifiers using them. We experiment with various feature selection techniques in order to extract the most discriminating features. To the best of our knowledge, this is the first study of its kind to combine these different sets of features for authorship analysis of Arabic tweets. The results show that combining all the feature sets we compute yields the best results

    Towards actionable knowledge: A systematic analysis of mobile patient portal use

    As the aging population grows, chronic illness increases, and our healthcare costs sharply increase, patient portals are positioned as a central component of patient engagement through the potential to change the physician-patient relationship and enable chronic disease self-management. A patient’s engagement in their healthcare contributes to improving health outcomes, and information technologies can support health engagement. In this chapter, we extend the existing literature by discovering design gaps for patient portals from a systematic analysis of negative users’ feedback from the actual use of patient portals. Specifically, we adopt a topic modeling approach, latent Dirichlet allocation (LDA) algorithm, to discover design gaps from online low rating user reviews of a common mobile patient portal, EPIC’s mychart. To validate the extracted gaps, we compared the results of LDA analysis with that of human analysis. Overall, the results revealed opportunities to improve collaboration and to enhance the design of portals intended for patient-centered care. Incorporating these changes may enable the technologies to have stronger position to influence health improvement and wellness

    AbstractBackgroundMedication safety is a global concern among healthcare providers. However, the challenges to and the future of medication safety in Saudi Arabia have not been explored.ObjectivesWe explored the perspectives of healthcare practitioners on current issues about medication safety in hospitals and community settings in Saudi Arabia in order to identify challenges to improving it and explore the future of medication safety practice.MethodsA total of 65 physicians, pharmacists, academics and nurses attended a one-day meeting in March 2010, designed especially for the purpose of this study. The participants were divided into nine round-table discussion sessions. Three major themes were explored in these sessions, including: major factors contributing to medication safety problems, challenges to improving medication safety practice, and participants’ suggestions for improving medication safety. The round-table discussion sessions were videotaped and transcribed verbatim and analyzed by two independent researchers.ResultsThe round-table discussions revealed that major factors contributing to medication safety problems included unrestricted public access to medications from various hospitals and community pharmacies, communication gaps between healthcare institutions, limited use of important technologies such as computerized provider order entry, and the lack of medication safety programs in hospitals. Challenges to current medication safety practice identified by participants included underreporting of medication errors and adverse drug reactions, multilingualism and differing backgrounds of healthcare professionals, lack of communication between healthcare providers and patients, and high workloads. Suggestions for improving medication safety practices in Saudi Arabia included continuous education for healthcare professionals and competency assessment focusing on medication safety, development of a culture that encourages medication error and adverse drug reactions reporting, use of technology proven to decrease medication errors, and promotion and implementation of national patient safety initiatives.ConclusionsHealthcare professionals have identified major challenges and opportunities for medication safety in Saudi Arabia. Policy makers and practitioners should consider these factors when designing future programs aimed at improving the safe use of medications

    <p>Abstract</p> <p>Background</p> <p>Computerized physician order entry (CPOE) systems are recommended to improve patient safety and outcomes. However, their effectiveness has been questioned. Our objective was to evaluate the impact of CPOE implementation on the outcome of critically ill patients.</p> <p>Methods</p> <p>This was an observational before-after study carried out in a 21-bed medical and surgical intensive care unit (ICU) of a tertiary care center. It included all patients admitted to the ICU in the 24 months pre- and 12 months post-CPOE (Misys<sup>®</sup>) implementation. Data were extracted from a prospectively collected ICU database and included: demographics, Acute Physiology and Chronic Health Evaluation (APACHE) II score, admission diagnosis and comorbid conditions. Outcomes compared in different pre- and post-CPOE periods included: ICU and hospital mortality, duration of mechanical ventilation, and ICU and hospital length of stay. These outcomes were also compared in selected high risk subgroups of patients (age 12-17 years, traumatic brain injury, admission diagnosis of sepsis and admission APACHE II > 23). Multivariate analysis was used to adjust for imbalances in baseline characteristics and selected clinically relevant variables.</p> <p>Results</p> <p>There were 1638 and 898 patients admitted to the ICU in the specified pre- and post-CPOE periods, respectively (age = 52 ± 22 vs. 52 ± 21 years, p = 0.74; APACHE II = 24 ± 9 vs. 24 ± 10, p = 0.83). During these periods, there were no differences in ICU (adjusted odds ratio (aOR) 0.98, 95% confidence interval [CI] 0.7-1.3) and in hospital mortality (aOR 1.00, 95% CI 0.8-1.3). CPOE implementation was associated with similar duration of mechanical ventilation and of stay in the ICU and hospital. There was no increased mortality or stay in the high risk subgroups after CPOE implementation.</p> <p>Conclusions</p> <p>The implementation of CPOE in an adult medical surgical ICU resulted in no improvement in patient outcomes in the immediate phase and up to 12 months after implementation.</p

    Discourse structure and language technology

    This publication is with permission of the rights owner freely accessible due to an Alliance licence and a national licence (funded by the DFG, German Research Foundation) respectively.An increasing number of researchers and practitioners in Natural Language Engineering face the prospect of having to work with entire texts, rather than individual sentences. While it is clear that text must have useful structure, its nature may be less clear, making it more difficult to exploit in applications. This survey of work on discourse structure thus provides a primer on the bases of which discourse is structured along with some of their formal properties. It then lays out the current state-of-the-art with respect to algorithms for recognizing these different structures, and how these algorithms are currently being used in Language Technology applications. After identifying resources that should prove useful in improving algorithm performance across a range of languages, we conclude by speculating on future discourse structure-enabled technology.Peer Reviewe

    Overview of medical errors and adverse events

    Safety is a global concept that encompasses efficiency, security of care, reactivity of caregivers, and satisfaction of patients and relatives. Patient safety has emerged as a major target for healthcare improvement. Quality assurance is a complex task, and patients in the intensive care unit (ICU) are more likely than other hospitalized patients to experience medical errors, due to the complexity of their conditions, need for urgent interventions, and considerable workload fluctuation. Medication errors are the most common medical errors and can induce adverse events. Two approaches are available for evaluating and improving quality-of-care: the room-for-improvement model, in which problems are identified, plans are made to resolve them, and the results of the plans are measured; and the monitoring model, in which quality indicators are defined as relevant to potential problems and then monitored periodically. Indicators that reflect structures, processes, or outcomes have been developed by medical societies. Surveillance of these indicators is organized at the hospital or national level. Using a combination of methods improves the results. Errors are caused by combinations of human factors and system factors, and information must be obtained on how people make errors in the ICU environment. Preventive strategies are more likely to be effective if they rely on a system-based approach, in which organizational flaws are remedied, rather than a human-based approach of encouraging people not to make errors. The development of a safety culture in the ICU is crucial to effective prevention and should occur before the evaluation of safety programs, which are more likely to be effective when they involve bundles of measures
