The effectiveness of the “Processo Especial de Revitalização” as an instrument of corporate restructuring in the context of the current economic crisis

This work project intends to evaluate the effectiveness of the Portuguese Government’s strategy to promote the orderly deleveraging of the corporate sector in the context of the current economic crisis. The recommendations of the Troika and the commitments assumed under the Memorandum of Understanding signed by the Government in 2011 required the creation of formal processes to avoid disorderly deleveraging. Conclusions and recommendations were drawn based on past experiences of large-scale corporate restructuring strategies in other countries and on the analysis of financial and statistical data on companies applying for “Programa Especial de Revitalização”.

Effects of quantitative easing on the USA economy: A test for policy effectiveness

The catastrophic disruption in the USA financial system in the wake of the financial crisis prompted the Federal Reserve to launch a Quantitative Easing (QE) programme in late 2008. In line with Pesaran and Smith (2014), I use a policy effectiveness test to assess whether this massive asset purchase programme was effective in stimulating the economic activity in the USA. Specifically, I employ an Autoregressive Distributed Lag Model (ARDL), in order to obtain a counterfactual for the USA real GDP growth rate. Using data from 1983Q1 to 2009Q4, the results show that the beneficial effects of QE appear to be weak and rather short-lived. The null hypothesis of policy ineffectiveness is not rejected, which suggests that QE did not have a meaningful impact on output growth.

A infecção por Helicobacter pylori em populações de Angola

RESUMO: A infecção por H. pylori, enquadra-se nas doenças infecciosas gastroduodenais e estima-se que mais de 50% da população mundial esteja infectada. A história natural da infecção por H. pylori, sofre interferências relacionadas com a genética do hospedeiro, a estirpe e as características da toxicidade da bactéria. Associam-se a estes factores, o tempo de exposição à infecção, assim como as condições sociais e higiéno-sanitárias. Paralelamente, o H. pylori é considerado o principal agente patogénico das doenças gastroduodenais. Este estudo teve como objectivo principal caracterizar a infecção por H. pylori em populações de Angola e sua avaliação como problema de Saúde Pública. Trata-se de um estudo prospectivo dirigido a dois grupos populacionais, um constituído por indivíduos aparentemente saudáveis, sem queixas gástricas específicas, em ambiente de comunidade, Grupo I, e outro, Grupo II, constituído por doentes que acorreram ao serviço de Gastrenterologia do Hospital Militar Principal de Luanda (HMP). No que diz respeito ao estudo na comunidade a pesquisa de H. pylori foi realizada pelo método ELISA de pesquisa de antigénios nas fezes. Por sua vez, a nível hospitalar, os métodos de diagnóstico da infecção por H. pylori foram: a endoscopia digestiva alta para a colheita de biópsias da mucosa gástrica destinadas ao exame anatomopatológico, ao exame citobacteriológico e aos métodos moleculares. Como método não invasivos foi utilizado o teste respiratório com ureia marcada. Grupo I: o diagnóstico da infecção por H. pylori, realizado pela pesquisa de antigénios deste microrganismo nas fezes, revelou uma frequência de 69,6% na população em estudo. Considerando em cada região, verificou-se que a região do Sambizanga possuía o valor mais elevado de frequência, 81,2%, seguida do Dinge com 79,5%, estatisticamente significativas (p 0,001). A avaliação da distribuição da frequência da infecção por grupo etário, revelou que os indivíduos com idade inferior a 15 anos, possuíam uma frequência de infecção de 63,5% e sendo de 76% nos indivíduos com idade superior a 15 anos. Este estudo permitiu concluir que a frequência da infecção por H. pylori nas regiões estudadas, é de 70% à excepção do Capulo, zona litoral em que não obstante as precárias condições de saneamento, a frequência da infecção por H. pylori é baixa. Grupo II: dos 309 doentes avaliados, verificou-se que 22 (7%), apresentavam uma mucosa normal e 287 (93%) uma mucosa alterada. A avaliação histológica das biópsias do antro, em 270 amostras de acordo com o Sistema de Sidney, em 235 (87,0%), revelou a presença de gastrite, 13 (4,8%) a presença de úlcera e em 9 (3,3%), uma lesão tumoral. A avaliação histológica da actividade nas 226 amostras do antro gástrico, verificou-se que 129 (57%) possuíam actividade e 97 (43%) não possuíam. O estudo das 255 biópsias do corpo, revelou em 212 (83,1%), a presença de lesões de gastrite, em 7 (2,7%), observaram-se lesões tumorais e 2 (0.8%) apresentaram úlcera. Dos 263 doentes avaliados histologicamente para pesquisa do H. pylori, 148 (58,2%) revelaram a presença positiva desta bactéria e 106 (41,7%) foram negativas. No que diz respeito à susceptibilidade aos macrólidos, do universo de 158 doentes com H. pylori positivo, 125 (79,1%) doentes apresentaram estirpes sensíveis aos macrólidos e 33 (20,9%) estirpes resistentes. Em relação aos factores de virulência, na avaliação conjunta dos dois factores de virulência estudados (cagA e vacA), em relação ao tipo de lesões encontradas na mucosa gástrica, verificou-se que dos 11 doentes com úlcera, 7 (63,6%), apresentavam uma estirpe cagA negativa, sendo 6 vacA s1 (85,7%), uma s2 e 4 (36,3%) com uma estirpe cagA positiva e vacA s1. Por sua vez dos 2 doentes com tumor, ambas as estirpes eram cagA negativas, sendo uma vacA s1 e outra vacA s2. Em relação aos factores de virulência nos doentes aos quais se diagnosticou úlcera e tumor apresentavam estirpe cagA negativa, vacAs1. Em relação ás lesões gástricas inflamatórias, os doentes com gastrite apresentavam cagA positivo. Do presente trabalho, em atenção aos resultados obtidos no que concerne a prevalência em populações sem queixas gastrenterológicas, recomenda-se que o mesmo se possa vir a replicar numa abrangência maior, realizando-se, por exemplo, estudos comparativos de prevalência entre as populações residentes no litoral (beira-mar) e as do interior. Pelas características genotípicas de H. pylori, em correspondência com as lesões encontradas, após novos estudos mais abrangentes, recomenda-se a avaliação de uma terapêutica mais acessível para o doente e que seja de maior eficácia. Face à escassez de médicos especialistas em gastrenterologia em Angola e de meios de diagnóstico, recomenda-se um estudo mais alargado da eficácia do seguimento do doente dispéptico, conforme protocolo avaliado pelo Colégio da Especialidade de Gastrenterologia da Ordem dos Médicos de Angola e já em prática em algumas instituições de saúde.--------------------------- ABSTRACT: H.pylori infection, is part of the gastroduodenal infectious diseases and it is estimated that over 50% of the world population is infected. The natural history of H.pylori infection, is influenced by host genetic, strain type, of bacterial virulence factors, time of exposure to the infection, as well as social and hygienic-sanitary conditions. In parallel, H.pylori is considered the main pathogen of gastroduodenal diseases. This study's main objective was to characterize H.pylori infection in populations of Angola and its evaluation as a public health problem. This is a prospective study conducted in two population groups, one in community environment composed by healthy individuals without specific gastric complaints - Group I, and Group II consisting of patients who went to the Gastroenterology Service of the Hospital Military of Luanda (HMP). As regards to the study in the community detection of H.pylori was carried out by antigen search in faeces using ELISA method. At hospital level H.pylori infection diagnostic methods were: upper gastrointestinal endoscopy to obtain gastric mucosal biopsies for histology, culture and molecular methods. As a non-invasive breath test with labelled urea was used. Group I: the diagnosis of H.pylori infection, by antigens detection in faeces, revealed a frequency of 69.6% in the study population. Whereas in each region, it was found that the Sambizanga region had the highest frequency of positive cases, 81.2% , followed by Dinge with 79.5%, Funda with 78.7 and Capulo with 39.8% being differences statistically significant (p=0.001). The evaluation of the distribution of the infection frequency by age group, revealed that individuals younger than 15 years had a frequency of 63.5% and in individuals older than 15 years, 76%. This study showed that the frequency of H.pylori infection in the regions studied was 70% exception due to Capulo, a coastal zone where despite the poor sanitation conditions; the frequency of H.pylori infection is lower. Group II: from the 309 patients evaluated, it was found that 22 (7%) had a normal mucosa and 287 (93%) a modified mucosa. Histological evaluation of antrum biopsies in 270 samples according to the Sydney System revealed the presence of gastritis in 235 (87.0%), the presence of ulcers in 13 (4.8%) and a tumour in 9 (3 3%). Histological assessment of activity in the gastric antrum of 226 samples, revealed that 129 (57%) had activity and 97 (43%) did not. The evaluation of the 255 corpus biopsies showed in 212 (83.1%), the presence of lesions of gastritis, in 7 (2.7%) tumour lesions and in 2 (0.8%) an ulcer. Of the 263 patients histological evaluated for H.pylori, 148 (58.2%) revealed the presence of this bacteria and 106 (41.7%) were negative. As regards susceptibility to macrolides from the universe of 158 patients with H.pylori, 125 (79.1%) patients had macrolides susceptible strains and 33 (20.9%) resistant strains. Regarding virulence factors (vacA and cagA), it was found that from the 11 patients with ulcers, 7 (63.6%), had a cagA negative strain, being 6 vacA s1, (85.7%) one vacA s2 and 4 (36.3%) with a cagA positive strain vacA s1. Concerning the 2 patients with tumour, both strains were cagA negative, one vacA s1 and other vacA s2. Patients with ulcer and tumour had cagA negative strains vacAs1. From this work, considering the prevalence of H.pylori obtained in health population, it is recommended that the same study should be performed in larger scale to confirm these results. The results of H.pylori genotyping suggest that more comprehensive studies are needed. Given the reduce number gastroenterology specialist in Angola and the lack of diagnostics methods, we recommend a larger study of the effectiveness of follow-up the patient dyspeptic, according to the protocol assessed by the College of Gastroenterology Specialty of the Order of Doctors and Angola already in place in some health institutions.

Furthermore, a careful analysis about the segmentation framing, the best market entry strategy and the consequences of adopting a joint venture with cable TV operators, is also provided. Finally, I present a SWOT analysis and highlight critical issues affecting the effectiveness of feedback which require further research.

Assessing Cybersecurity service quality in corporate environments

This study assess the quality of Cybersecurity as a service provided by IT department in corporate network and provides analysis about the service quality impact on the user, seen as a consumer of the service, and on the organization as well. In order to evaluate the quality of this service, multi-item instrument “SERVQUAL” was used for measuring consumer perceptions of service quality. To provide insights about Cybersecurity service quality impact, DeLone and McLean information systems success model was used. To test this approach, data was collected from over one hundred users from different industries and partial least square (PLS) was used to estimate the research model. This study found that SERVQUAL is adequate to assess Cybersecurity service quality and also found that Cybersecurity service quality positively influences the Cybersecurity use and individual impact in Cybersecurity.

The role of the intelligence service in preventing and combating transnational terrorism

Outrora dominado por ameaças provenientes de Estados-nação, o cenário global actual, dominado por uma rápida mudança de poderes que nos apresenta uma interacção complexa entre múltiplos actores, onde inimigos desconhecidos, anteriormente bem identificados, é actualmente controlado por grupos terroristas bem preparados e bem organizados. Hezbollah é reconhecido como um dos grupos terroristas mais capazes, com uma extensa rede fora do Líbano dedicada a tráfico de droga, armas e seres humanos, tal como o branqueamento de capitais para financiar o terrorismo, representando um grande foco de instabilidade à segurança. Como instrumento de Estado, os serviços de informações detêm a capacidade de estar na linha da frente na prevenção e combate ao terrorismo. Todavia, para compreender este fenómeno é necessário analisar os actores desta ameaça. À luz desta conjuntura, esta dissertação está dividida em três capítulos principais que visam responder às seguintes questões fundamentais: O que é o terrorismo? Como opera um grupo terrorista transnacional? Será que os serviços de informações têm as ferramentas necessárias para prevenir e combater estas ameaças?

Decentralization and privatization in Portuguese health reforms

ABSTRACT - The Portuguese National Health Service (SNS), a universal, centralized and public owned health care system, exhibits an extraordinary record of equalization in the access to health care and health gains in the late thirty years. However, the most recent history of the Portuguese health reform is pervaded by the influence of decentralization and privatization. Decentralization has been present in the system design since the 1976 Constitution, at least in theory. Private ownership of health care suppliers and out-ofpocket expenditures, on the financing side, both have a long tradition of relevance in the NHS mix of services. The initial aim of this study was to demonstrate expected parallelism between health reforms and public administration reforms, where a common pattern of joint decentralization and privatization was observed in many countries. Observers would be tempted to consider these two movements as common signs of new public management (NPM) developments. They have common objectives, are established around the core concepts of gains in effectiveness, efficiency, equity and quality of public services, through improved accountability. However, in practice, in Portugal, each movement was developed in a totally separated way. Besides those rooted in the NPM theory, there are few visible signs of association between decentralization and privatization. Decentralization, in the Portuguese SNS, was never intended to be followed by a privatization movement; it was seen merely as a public administration tool. Private management of health services, as stated in the most recent SNS legislation, was never intended to have decentralization as a condition or as a consequence. Paradoxically, in the Portuguese context, it has led invariably to centralized control. While presented as separate instruments for a common purpose, the association between decentralization and privatization still lacks a convincing demonstration. Many common health care management stereotypes remain to be checked out if we want to look for eventual associations between these two organizational tools.

Contribution of Mental Health Service User Groups to Mental Health Services and Policy in Ghana : The Case of Mental Health Society of Ghana

RESUMO: Este estudo procurou documentar a perspectiva (s) dos utentes de saúde mental e das associações de prestadores de cuidados sobre a prestação, o papel e a contribuição de serviços de saúde mental da comunidade tal como foram percebidos por um número de informadores-chave, incluindo os utentes do serviço mentais e os próprios prestadores de cuidados. O caso específico da Sociedade Saúde Mental do Gana (MEHSOG) foi o foco deste estudo. O modelo foi o de um estudo de caso, utilizando discussões de grupo e entrevistas com informadores-chave como instrumentos de recolha de dados. Estas ferramentas de colheita de dados foram complementadas por observações dos participantes e pela revisão de documentos da MEHSOG e dos vários grupos de apoio da comunidade de auto-ajuda que compõem a associação nacional. O estudo revelou que os utentes dos serviços de saúde mental e seus prestadores de cuidados constituem um importante grupo de partes interessadas na prestação de serviços de saúde mental da comunidade e no desenvolvimento de políticas que tenham em conta as necessidades e os direitos das pessoas com doença mental ou epilepsia. O envolvimento da MEHSOG promove a mobilização de membros e famílias relacionadas com a doença mental de beneficiar de serviços de tratamento bem organizados com um impacto significativo na melhoria da saúde e da participação dos utentes dos serviços e seus prestadores de cuidados primários em processos de tomada de decisão da família e na comunidade processos de desenvolvimento. Os utentes dos serviços por beneficiarem de tratamento, e os prestadores de cuidados primários, por se tornarem mais livres e menos sobrecarregados com a responsabilidade de cuidar, podem passar a envolver-se mais em atividades que melhoramo seu estado, o de suas famílias e das comunidades. A advocacia dos membros da MEHSOG para conseguir que a “Mental Health Bill” se transforme numa Lei foi também um desenvolvimento significativo resultante da participação ativa dos utentes do serviço em chamar a atenção para uma nova e inclusiva legislação de saúde mental para o Gana. Entre os fatores e oportunidades que permitiram aos utentes dos serviços de saúde mental e aos prestadores de cuidados primários de pessoas com doença mental apoiar activamente a prestação de serviços de saúde mental comunitária e o desenvolvimento de políticas conta-se a contribuição da sociedade civil do Gana, particularmente o movimento da deficiência, e os esforços anteriores de ONGs em saúde mental e dos profissionais de saúde mental para ter uma nova lei em saúde mental. Observámos um certo número de desafios e barreiras que actuam de forma a limitar a influência dos utentes dos serviços de saúde mental na provisão da saúde mental comunitária e no desenvolvimento de políticas. Entre elas o estigma social contra a doença mental e pessoas com doença mental ou epilepsia e seus cuidadores primaries é um factor chave. O estigma tem alterado a percepção e as análises do público em geral, especialmente dos profissionais de saúde e das autoridades políticas afetando a priorização dos problemas de saúde mental nas políticas e programas. Outro desafio foi a deficiente infra-estrutura disponível para apoiar serviços de saúde mentais que assegurem aos utentes permanecerem em bom estado de saúde e bem-estar para serem advogados de si próprios. A recomendação do presente estudo é que os movimentos de utentes dos serviços de saúde mental são importantes e que eles precisam de ser apoiados e encorajados a desempenhar o seu papel como pessoas com experiência vivida para contribuir para a organização e prestação de serviços de saúde mental, bem como para a implementação, monitorização e avaliação de políticas e programas. ------------------------------------ ABSTRACT: This study sought to document the perspective(s) of mental health users and care-givers associations in community mental health service provision and their role and contribution as it was perceived by a number of key informants including the mental service users and care-givers themselves. The specific case of the Mental Health Society of Ghana (MEHSOG) was the focus of this study. A case study approach was used to with Focus Group Discussions and Key Informants Interviews being the data collection tools that were used. These data collection tools were complemented by participant observations and review of documents of the MEHSOG and the various community self-help peer support groups that make up the national association. The study revealed that mental health service users and their care-givers constitute an important stakeholder group in community mental health service provision and development of policies that factor in the needs and rights of persons with mental illness or epilepsy. MEHSOG’s involvement in mobilising members and education families to come forward with the relations with mental illness to benefit from treatment services were well made a significant impact in improving the health and participation of service users and their primary carers in family decision-making processes and in community development processes. Service users, on benefiting from treatment, and primary care-givers, on becoming freer and less burdened with the responsibility of care, move on to engage in secure livelihoods activities, which enhanced their status in their families and communities. The advocacy MEHSOG members undertook in getting the mental health Bill become Law was also noted as significant development that was realised as a result of active involvement of service users in calling for a new and inclusive mental health legislation for Ghana. Enabling factors and opportunities that enabled mental health service users and primary care-givers of people with mental illness to actively support community mental health service provision and policy development is with the vibrant civil society presence in Ghana, particularly the disability movement, and earlier efforts by NGOs in mental health in Ghana long-side mental health professionals to have a new law in mental health. A number of challenges were also noted which were found to limit the extent to which mental health service users can be influential in community mental health service provision and policy development. Key among them was the social stigma against mental illness and people with mental illness or epilepsy and their primary carers. Stigma has affected perceptions, analyses of the general public, especially health practitioners and policy authorities that it has affected their prioritisation of mental health issues in policies and programmes. Another challenge was the poor infrastructure available to support enhanced mental health care services that ensure mental health service users remain in a good state of health and wellbeing to advocate for themselves. The recommendation from the study is that mental health service user movements are important and need to be supported and encouraged to play their role as persons with lived experience to inform organisation and provision of mental health services as well as design and implementation, monitoring and evaluation of policies and programes.

Young adult Brazilian beauty consumers perception of Lancôme and the effectiveness of social media relationhips with local celebrities on their purchase intention

The aim of this research is to evaluate if a premium beauty brand, in this case, Lancôme, can influence positively the purchase intention from Brazilian young adults, between 18 and 29 years old, consumers of beauty products, by initiating a relationship with a local celebrity or “it” girl on social media. This hypothesis has not been tested, and this research is a first attempt of evaluating it. Additionally, the consumer behavior, brand preferences and social media activeness of this age segment in Brazil are further studied as important insights for beauty brands to conquer these consumers. Results did not confirm the positive influence of local celebrities on this age segment’s purchase intention but several suggestions are made for future research to revisit this topic. Furthermore, there is a significant brand love for M.A.C., an international Lancôme competitor, amongst this target, as well as a probable price sensitivity facing premium beauty brands.

An effective on-the-job training model-to facilitate strategy execution

Strategy execution has been a heated topic in the management world in recent years. However, according to a survey done by the Conference Board (2014), the chief executives are so concerned about the execution in their companies and have rated it as the No.1 or No.2 most challenging issue. Many of them choose to invest in training with a purpose to harvest the most for strategy execution. Therefore, this research is trying to find out a model to design training programs that can at most contribute to the success of strategy execution with three real-life training cases done by BTS Consulting Service. It was found that strategy execution could be greatly supported by training programs that take into consideration the four factors, namely Alignment, Mindset to Change, Capability and Organization Support. Main implications of the findings are presented and discussed. Key
