Resilience of logistic service providers facing a port strike: a case study

The purpose of this thesis is to study the impact of a port strike on companies that perform as logistic service providers in a supply chain (SC), here denominated 3PL (third-party logistic providers). These companies are highly dependent on ports to perform their activity, since they provide international services. Consequently, a disruption in a port can seriously impair their business. A stevedores’ strike is one of the possible disruptions that can affect ports. This study aims to analyze the negative effects caused by this disruption, and what strategies 3PLs may implement in order to keep their performance levels stable and have a quick recovery time. Within this objective, the first step will be to establish a theoretical context about the maritime port’s sector and 3PLs in a SC context, to then expand the concept of a resilient SC, and finally to develop a theoretical framework in order to better contextualize the case study. Subsequently, the impact of a port strike will be quantified by using a case study comprising three companies, covering the areas of land and sea distribution and port operations. Information from primary sources was assembled in two phases: first via e-mail and, in a second phase, through a personal interview. The information from secondary sources was obtained through television news, internet and conferences, enabling its cross-analysis. Finally, by analyzing the collected data, it will be possible to draw conclusions about the measures carried out by each company to minimize the negative effects of the strike, thus contributing to a more resilient SC. As a conclusion, a stevedores’ strike will create a snow-ball of negative effects in the SC, degrading all relevant KPIs (key performance indicators) of the 3PLs under study. No mitigation and contingency strategies available proved really effective to reduce the negative effects of a port strike disruption.

Achieving better service level results, through improvements in procedures

This project aims to prepare Worten Empresas (WE) fulfilling the increasing market demand through process changings, focusing on the Portuguese market, particularly on internal B2B clients1. Several methods were used to measure the current service level provided - process mapping, resources assessment, benchmark and a survey. The results were then used to compare against service level actually desired by WE’s customer, and then to identify the performance gaps in response times and quality of the follow-up during the sales process. To bridge the identified gaps, both a set of recommendations and an implementation plan were suggested to improve and monitor customer experience. This study concluded that it is possible to fulfill the increasing level of demand and at the same time improve customer satisfaction by implementing changes at the operations level.

Tuberculosis incidence and risk factors among patients living with HIV/AIDS in public health service institutions in Brasilia, Federal District

In order to estimate the incidence of and risk factors for developing tuberculosis, the clinical charts of a retrospective cohort of 281 HIV-positive adults, who were notified to the AIDS Program of the Health Department of Brasilia in 1998, were reviewed in 2003. All the patients were treatment-naive regarding antiretroviral therapy at the time of inclusion in the cohort. Twenty-nine patients were identified as having tuberculosis at the start of the study. Thirteen incident tuberculosis cases were identified during the 60 months of follow-up, with an incidence density rate of 1.24/100 person-years. Tuberculosis incidence was highest among patients with baseline CD4+ T-lymphocyte counts < 200 cells/µl who were not using antiretroviral therapy (incidence = 5.47; 95% CI = 2.73 to 10.94). Multivariate analysis showed that baseline CD4+ T-lymphocyte counts < 200 cells/µl (adjusted hazard ratio [AHR] = 5.09; 95% CI = 1.27 to 20.37; p = 0.02) and non-use of antiretroviral therapy (AHR = 12.17; 95% CI = 2.6 to 56.90; p = 0.001) were independently associated with increased risk of tuberculosis.

Teleoperation of a service robot using a mobile device

Teleoperation is a concept born with the rapid evolution of technology, with an intuitive meaning "operate at a distance." The first teleoperation system was created in the mid 1950s, which were handled chemicals. Remote controlled systems are present nowadays in various types of applications. This dissertation presents the development of a mobile application to perform the teleoperation of a mobile service robot. The application integrates a distributed surveillance (the result of a research project QREN) and led to the development of a communication interface between the robot (the result of another QREN project) and the vigilance system. It was necessary to specify a communication protocol between the two systems, which was implemented over a communication framework 0MQ (Zero Message Queue). For the testing, three prototype applications were developed before to perform the test on the robot.

The role of qualitative data and systems thinking in addressing service decline in market towns

Retail services are a main contributor to municipal budget and are an activity that affects perceived quality-of-life, especially for those with mobility difficulties (e.g. the elderly, low income citizens). However, there is evidence of a decline in some of the services market towns provide to their citizens. In market towns, this decline has been reported all over the western world, from North America to Australia. The aim of this research was to understand retail decline and enlighten on some ways of addressing this decline, using a case study, Thornbury, a small town in the Southwest of England. Data collected came from two participatory approaches: photo-surveys and multicriteria mapping. The interpretation of data came from using participants as analysts, but also, using systems thinking (systems diagramming and social trap theory) for theory building. This research moves away from mainstream economic and town planning perspectives by making use of different methods and concepts used in anthropology and visual sociology (photo-surveys), decision-making and ecological economics (multicriteria mapping and social trap theory). In sum, this research has experimented with different methods, out of their context, to analyse retail decline in a small town. This research developed a conceptual model for retail decline and identified the existence of conflicting goals and interests and their implications for retail decline, as well as causes for these. Most of the potential causes have had little attention in the literature. This research also identified that some of the measures commonly used for dealing with retail decline may be contributing to the causes of retail decline itself. Additionally, this research reviewed some of the measures that can be used to deal with retail decline, implications for policy-making and reflected on the use of the data collection and analysis methods in the context of small to medium towns.

AGNI: an API for the control of automomous service robots

With the continuum growth of Internet connected devices, the scalability of the protocols used for communication between them is facing a new set of challenges. In robotics these communications protocols are an essential element, and must be able to accomplish with the desired communication. In a context of a multi-­‐‑agent platform, the main types of Internet communication protocols used in robotics, mission planning and task allocation problems will be revised. It will be defined how to represent a message and how to cope with their transport between devices in a distributed environment, reviewing all the layers of the messaging process. A review of the ROS platform is also presented with the intent of integrating the already existing communication protocols with the ServRobot, a mobile autonomous robot, and the DVA, a distributed autonomous surveillance system. This is done with the objective of assigning missions to ServRobot in a security context.

Context classification for service robots

This dissertation presents a solution for environment sensing using sensor fusion techniques and a context/environment classification of the surroundings in a service robot, so it could change his behavior according to the different rea-soning outputs. As an example, if a robot knows he is outdoors, in a field environment, there can be a sandy ground, in which it should slow down. Contrariwise in indoor environments, that situation is statistically unlikely to happen (sandy ground). This simple assumption denotes the importance of context-aware in automated guided vehicles.

Methodological framework for detection of harmonisation breaking in service environments

As the complexity of markets and the dynamicity of systems evolve, the need for interoperable systems capable of strengthening enterprise communication effectiveness increases. This is particularly significant when it comes to collaborative enterprise networks, like manufacturing supply chains, where several companies work, communicate, and depend on each other, in order to achieve a specific goal. Once interoperability is achieved, that is once all network parties are able to communicate with and understand each other, organisations are able to exchange information along a stable environment that follows agreed laws. However, as markets adapt to new requirements and demands, an evolutionary behaviour is triggered giving space to interoperability problems, thus disrupting the sustainability of interoperability and raising the need to develop monitoring activities capable of detecting and preventing unexpected behaviour. This work seeks to contribute to the development of monitoring techniques for interoperable SOA-based enterprise networks. It focuses on the automatic detection of harmonisation breaking events during real-time communications, and strives to develop and propose a methodological approach to handle these disruptions with minimal or no human intervention, hence providing existing service-based networks with the ability to detect and promptly react to interoperability issues.

Epidemiological, clinical, and operational aspects of leprosy patients assisted at a referral service in the state of Maranhão, Brazil

INTRODUCTION: Leprosy is an infectious disease caused by Mycobacterium leprae. The aim of this study was to describe the epidemiological, clinical, and operational aspects of leprosy carriers. METHODS: A cross-sectional study leprosy patients assisted in São Luis, MA, was performed. RESULTS: Of the 85 cases analyzed, 51.7% were male participants, and 60% were brown. Concerning the age, 54.8% of women were between 35 and 49 years, and 57.6% of men were between 20 and 34 years. Lepromatous leprosy was found in 42.3% of cases, and the multibacillary form was found in 72.9%. The skin smear was positive in 42.3%. The occurrence of reaction was found in 43.5% of cases, and 83.5% had no Bacillus Calmette-Guérin scar. Leprosy in the family was reported by 44.7% of the patients. Most of the individuals (96.4%) lived in houses made of brick with more than three rooms (72.6%) and two persons per room (65.1%). Concerning the level of education, 41.4% of women and 34.1% of men had more than one to three years of education. The most evaluated age group in the beginning of the treatment was that of 35 to 49 years with a Grade 0 incapability (64.5%), and that in the end was the age group of 20 to 34 (29.9%) with Grade 0, 30.7% Grade 1, and 11.5% Grade 2. CONCLUSIONS: The frequency of multibacillary forms found in this study and the cases in family members point out delayed diagnoses. Thus, early diagnosis and appropriate treatment are important in decreasing the outcome of disabilities.

Assessing the community needs of mental health residential care service users in Republic of Moldova

RESUMO: Background: Problemas de saúde mental são um grande problema clínico e social na República da Moldávia, representando uma quota significante de deficiência, sendo classificada no top cinco das dez linhas na hierarquia das condições. A taxa de incidência tem sido crescente na República da Moldávia, atingindo cerca de 15.000 por ano (14,655 em 2011), ou seja, 411,4 por 100 mil habitantes, e uma taxa de prevalência de 97.525 pessoas em 2011, ou seja, 2,737.9 por 100 mil habitantes. Sistema de atendimento psiquiátrico fornece serviços de saúde mental escassos a nível da comunidade, visando principalmente terapia hospitalar, centralizada, através de uma rede de três hospitais psiquiátricos, com 1.860 camas e 4 sanatórios psico- neurológicos com 1890 camas, assim alimentando-se a estigmatização do paciente. Objetivos: O objetivo deste estudo foi a avaliação das necessidades individuais dos beneficiários e do seu nível de autonomia dentro de cuidados residenciais, para o planeamento de reformas de saúde mental e desinstitucionalização na República da Moldávia. Este estudo foi encomendado pelo Ministério do Trabalho, Proteção Social e da Família e pelo Ministério da Saúde, com o apoio da Organização Mundial da Saúde, para determinar o cumprimento eficaz do artigo 19 da Convenção da ONU. O estudo tem os seguintes objetivos: Avaliar o nível de autonomia dos residentes nos hospitais psiquiátricos e sanatórios psico-neurológico, usando uma amostra representativa de 10 por ce nto do número total de pacientes/residentes e comparação cruzada; Para avaliar quatro sanatórios psico-neurológicos para adultos e três hospitais psiquiátricos; Para desenvolver recomendações para o planeamento da desinstitucionalização das pessoas com problemas de saúde mental e colocação na comunidade com base nos resultados do estudo. Metodologia e resultados: O estudo fez uso de duas ferramentas globais: questionário para a avaliação individual dos residentes do estabelecimento de saúde mental, e questionário de avaliação institucional. Todos os entrevistados foram divididos em quatro categorias conforme com o grau de dependência e preparação de viver de forma independente na comunidade. Apenas 1,2% dos entrevistados de PNHB eram totalmente dependentes de terceiros ou serviços especializados, tornando-se a categoria 4, que necessitam de cuidados e apoio contínuo. No PH esta categoria de pessoas é ausente. Conclusões: A condição dos entrevistados foi pior em PNBH que em PH. No entanto, ainda, aqueles que estão prontos para ser desinstitucionalizados correspondem com a maior parte dos entrevistados. Todos os hospitais tinham o consentimento do utente para admissão e tratamento, enquanto não houve consentimento qualquer em PNBH. É bastante óbvio que tanto os hospitais como também a sistema de assistência residencial não atingem a sua finalidade, o que significa que a maioria dos utentes pode ser desinstitucionalizados, sem qualquer terapia de suporte.------------------ABSTRACT: Background: Mental health problems are a major clinical and social issue in the Republic of Moldova,accounting for a significant share of disability and ranking in top five of the ten lines in the hierarchy of conditions. The incidence rate has been growing in the Republic of Moldova to reach approximately 15 thousand a year (14,655 in 2011), i.e. 411.4 per 100 thousand population, and a prevalence rate of 97,525 thousand people in 2011, i.e. 2,737.9 per 100 thousand population. Psychiatric care system provides for scanty mental health services at community level, aiming mainly at centralized hospital-based therapy through a network of three psychiatric hospitals tallying up 1,860 beds and 4 psycho-neurological boarding houses with 1,890 beds, thus fuelling up patient stigmatization. Objectives: The purpose of this study was to assess the individual needs of beneficiaries and their level of autonomy within residential care for the planning of mental health system reforms and deinstitutionalization in the Republic of Moldova. This study was commissioned by the Ministry of Labour, Social Protection and Family and by the Ministry of Health, with the World Health Organization support, to provide for effective enforcement of article 19 of the UN CRPD. The study pursued the following goals: To evaluate the level of autonomy of the psychiatric hospital and psycho-neurological boarding house residents by using a representative sample of 10 per cent of the total number of patients / residents and cross-comparison; To evaluate four psycho-neurological boarding houses for adults and three psychiatric hospitals; To develop recommendations for planning the deinstitutionalization of people with mental health problems and community placement based on the study findings.Methodology and results: The study made use of two global tools: questionnaire for individual assessment of mental health facility residents, and institutional assessment questionnaire. All interviewees were divided into four categories by one’s degree of dependence and readiness to live independently in the community. Only 1.2% of respondents from PNHB were fully dependent on a third party or specialized services, making up category 4, requiring continuous care and support. In PH this category of people is absent.Conclusions: The condition of respondents was worse in PNBH than in PH. However, yet, those ready to be deinstitutionalized accounted for most of respondents there. All hospitals had the resident’s consent to admission and treatment, whereas there was no consent in PNBH whatsoever. It is quite obvious that both the hospitals and residential care system do not achieve their intended purpose, meaning that the majority of residents may be deinstitutionalized without any support therapy.

Late diagnosis and HIV infection in children attending a service of specialized care for pediatric AIDS in Brazil

Introduction: This study describes the frequency of late diagnosis and HIV among children attending a pediatric AIDS clinic. Methods: Cross-sectional study in children exposed to HIV from 2005-2008. A questionnaire was given that included questions on demographics and clinical information. Results: Two-hundred twenty-one (97.8%) children were exposed to HIV during pregnancy/childbirth. A total of 193 (87.3%) children had late enrolment in the service and late access to HIV serology. The frequency of HIV was 21.3% (95% confidence interval [CI] 15.9%-26.7%). Protective factors were earlier diagnosis [odds ratio (OR)=0.17 (0.08-0.37)] and receiving complete prophylaxis [OR=0.29 (0.09-0.97)]; being born by vaginal delivery was a risk factor [OR=4.45 (1.47-13.47)]. Conclusions: There was a high frequency of late diagnosis in this patient cohort. Earlier diagnosis is an important measure for controlling HIV among children.

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.

Assessment of medical courses in Brazil using student-completed questionnaires. Is it reliable?

INTRODUCTION: Debates about the quality of medical education have become more evident in the recent past, and as a result several different assessment methods have been refined for that purpose. The use of questionnaires filled out by medical students to assess the quality of lectures is one of the most common methods employed in our milieu. However, the reliability of this investigation method has not yet been systematically tested. The authors present the reliability of a specific form applied to the fourth grade medical students during the clinical psychiatry course. METHOD: Eighty-one fourth grade medical students were instructed to complete a form immediately after each clinical psychiatry lecture. Thirty-four students (42%) failed to turn in the forms after the final lecture. These students were given an identical form to assess the lectures in a retrospective fashion. The grades given by both groups of students for each performed lecture and the number of students who have graded an unperformed lecture were compared. Statistical significance for both groups was determined by means of the chi-square test (p< 0.05). RESULTS: Eighteen out of the 34 students who filled out the forms retrospectively (53%) rated the unperformed lecture, whereas only 5 out of the 47 students who filled out the forms during the course (11%) did so. This is statistically significant (p< 0.05). There was no statistical difference for the grades given to the lectures that were actually performed. DISCUSSION: The authors concluded the low reliability rate of the retrospective evaluation warrant a continuous assessment method during the course.

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?
