A client focused business intelligence & analytics solution for the hospitality sector
Project Work presented as the partial requirement for obtaining a Master's degree in Information Management, specialization in Knowledge Management and Business IntelligenceOne of the greatest needs of today's business is to know the customer or the type of customer it
wants to reach, which makes a customer database a strategic weapon and one of the most important
investments a company can make. The business world is becoming more competitive every day, we
are constantly overwhelmed with advertisements of products we may like, product promotions we
usually buy or discounts on the next purchase if we subscribe to the company’s newsletter. All of this
creates a client customization, and any company that is not able to do this cannot keep up with its
competition. This report details the project developed at Pestana Hotel Group, which consisted of a
Business Intelligence solution, more specifically the development of a customer database with the
creation of two tabular models using SQL Server tools, one specific for loyal customers and another,
more general, with information about all Pestana customers, and two Power BI reports that allow
the visualization of the information obtained in an effective and simplified way. This report contains
a literature review that situates the reader on the subject addressed in this project, a chapter
dedicated to the data modeling used to create the tabular models, and another on the creation of
the reports.Uma das maiores necessidades dos negócios atuais é conhecer o seu cliente ou o tipo de cliente que
quer atingir, o que torna uma base de dados de cliente uma arma estratégica e um dos mais
importantes investimentos. O mundo empresarial está cada dia mais competitivo, somos
constantemente assoberbados com anúncios de produtos que podemos gostar, promoções de
produtos que costumamos comprar ou descontos na próxima compra caso subscrevamos a
newsletter. Tudo isto cria uma personalização para o cliente, e qualquer empresa que não o consiga
fazer não conseguirá acompanhar a concorrência. Este relatório detalha o projeto feito no Pestana
Hotel Group, que consistiu numa solução de Business Intelligence, mais especificamente na
construção de uma base de dados do cliente com a criação de dois modelos tabulares através de
ferramentas do SQL Server, um específico para clientes fidelizados e outro mais geral com
informação sobre todos os clientes Pestana, e dois relatórios em Power BI que permitem a
visualização da informação obtida de uma forma eficaz e simplificada. O relatório contém uma
revisão de literatura que situa o leitor sobre os assuntos abordados neste projeto, um capítulo
dedicado à modelação dos dados de forma a criar os modelos tabulares e outro sobre a criação dos
relatórios
Relações entre cultura organizacional e Qualidade de Vida no Trabalho no setor hoteleiro
Abstract.The objective of this study is to analyze the characteristics of organizational culture as a tool for quality of working life practices in the hotel sector. A semi-structured script was used and the content analysis technique was applied in interviews with the Human Resources coordinators of two hotels in the city of Goiânia - GO. The results revealed that the level of management and operations of the hotel chains induce the people management guidelines and their applications in the employees' routine. It is concluded that the organizational culture profile most favorable to good QLW practices is the one in which artifacts and values define the systematization of work and influence the positive perception of employees about quality of working life.

A Dynamic Analysis of Tuberculosis Dissemination to Improve Control and Surveillance
Background: Detailed analysis of the dynamic interactions among biological, environmental, social, and economic factors that favour the spread of certain diseases is extremely useful for designing effective control strategies. Diseases like tuberculosis that kills somebody every 15 seconds in the world, require methods that take into account the disease dynamics to design truly efficient control and surveillance strategies. The usual and well established statistical approaches provide insights into the cause-effect relationships that favour disease transmission but they only estimate risk areas, spatial or temporal trends. Here we introduce a novel approach that allows figuring out the dynamical behaviour of the disease spreading. This information can subsequently be used to validate mathematical models of the dissemination process from which the underlying mechanisms that are responsible for this spreading could be inferred. Methodology/Principal Findings: The method presented here is based on the analysis of the spread of tuberculosis in a Brazilian endemic city during five consecutive years. The detailed analysis of the spatio-temporal correlation of the yearly geo-referenced data, using different characteristic times of the disease evolution, allowed us to trace the temporal path of the aetiological agent, to locate the sources of infection, and to characterize the dynamics of disease spreading. Consequently, the method also allowed for the identification of socio-economic factors that influence the process. Conclusions/Significance: The information obtained can contribute to more effective budget allocation, drug distribution and recruitment of human skilled resources, as well as guiding the design of vaccination programs. We propose that this novel strategy can also be applied to the evaluation of other diseases as well as other social processes.Instituto do Milenio REDE-TBConselho Nacional de Desenvolvimento Cientifico e Tecnologico (CNPq)Coordenacao de Aperfeicoamento de Pessoal de Nivel Superior (CAPES)Fundacao de Amparo a Pesquisa do Estado de Sao Paulo (FAPESP)Fundacao de Amparo a Ciencia e Tecnologia do Estado de Pernambuco (FACEPE)[0012-05.03/04]Fundacao de Amparo a Ciencia e Tecnologia do Estado de Pernambuco (FACEPE)[0203-1.05/08

Methods: Multicenter, prospective, observational study of a cohort of preterm infants born with gestational age (GA) < 32 weeks or birth weight < 1500 g in eight Portuguese neonatal intensive care units. All demographic, clinical, and laboratory data from the first week of life were collected. Univariate logistic regression was used to assess risk factors for ROP and then multivariate regression was performed.
Results: A total of 455 infants were included in the study. The median GA was 29.6 weeks, and the median birth weight was 1295 g. One hundred and seventy-two infants (37.8%) developed ROP. Median values of erythrocytes (p < 0.001), hemoglobin (p < 0.001), hematocrit (p < 0.001), mean corpuscular hemoglobin concentration (p < 0.001), lymphocytes (p = 0.035), and platelets (p = 0.003) of the group of infants diagnosed with ROP any stage were lower than those without ROP. Mean corpuscular volume (MCV) (p = 0.044), red blood cell distribution width (RDW) (p < 0.001), erythroblasts (p < 0.001), neutrophils (p = 0.030), neutrophils-lymphocytes ratio (p = 0.028), and basophils (p = 0.003) were higher in the ROP group. Higher values of MCV, erythroblasts, and basophils remained significantly associated with ROP after multivariate regression.
Conclusion: In our cohort, the increase in erythroblasts, MCV, and basophils in the first week of life was significantly and independently associated with the development of ROP. These CBC parameters may be early predictive biomarkers for ROP.Open access funding provided by FCT|FCCN (b-on).

SARS-CoV-2 introductions and early dynamics of the epidemic in Portugal
Genomic surveillance of SARS-CoV-2 in Portugal was rapidly implemented by
the National Institute of Health in the early stages of the COVID-19 epidemic, in collaboration
with more than 50 laboratories distributed nationwide.
Methods By applying recent phylodynamic models that allow integration of individual-based
travel history, we reconstructed and characterized the spatio-temporal dynamics of SARSCoV-2 introductions and early dissemination in Portugal.
Results We detected at least 277 independent SARS-CoV-2 introductions, mostly from
European countries (namely the United Kingdom, Spain, France, Italy, and Switzerland),
which were consistent with the countries with the highest connectivity with Portugal.
Although most introductions were estimated to have occurred during early March 2020, it is
likely that SARS-CoV-2 was silently circulating in Portugal throughout February, before the
first cases were confirmed.
Conclusions Here we conclude that the earlier implementation of measures could have
minimized the number of introductions and subsequent virus expansion in Portugal. This
study lays the foundation for genomic epidemiology of SARS-CoV-2 in Portugal, and highlights the need for systematic and geographically-representative genomic surveillance.We gratefully acknowledge to Sara Hill and Nuno Faria (University of Oxford) and

Transition of plasmodium sporozoites into liver stage-like forms is regulated by the RNA binding protein pumilio
Many eukaryotic developmental and cell fate decisions that are effected post-transcriptionally involve RNA binding proteins as regulators of translation of key mRNAs. In malaria parasites (Plasmodium spp.), the development of round, non-motile and replicating exo-erythrocytic liver stage forms from slender, motile and cell-cycle arrested sporozoites is believed to depend on environmental changes experienced during the transmission of the parasite from the mosquito vector to the vertebrate host. Here we identify a Plasmodium member of the RNA binding protein family PUF as a key regulator of this transformation. In the absence of Pumilio-2 (Puf2) sporozoites initiate EEF development inside mosquito salivary glands independently of the normal transmission-associated environmental cues. Puf2- sporozoites exhibit genome-wide transcriptional changes that result in loss of gliding motility, cell traversal ability and reduction in infectivity, and, moreover, trigger metamorphosis typical of early Plasmodium intra-hepatic development. These data demonstrate that Puf2 is a key player in regulating sporozoite developmental control, and imply that transformation of salivary gland-resident sporozoites into liver stage-like parasites is regulated by a post-transcriptional mechanism

Physiological responses and production of 'Syrah' vines as a function of training systems
Plant architecture and its interaction with agricultural practices and environmental constraints is determinant for grapevine canopy structure, which is related to carbon assimilation, bud fertility and fruit quality. In this context, this study evaluated the performance of field-grown 'Syrah' grapevines conducted by two management systems: Vertical Shoot Position (VSP) or a modified Geneva Double Curtain (GDC), in Pirapora, state of Minas Gerais, Brazil, during the winters of 2007 and 2008. The evaluations of leaf area, water relations and net CO2 assimilation were made at the end of the ripening period. Yield per vine and per hectare were estimated and mean berry weight and diameter, total soluble solids, pH and titratable acidity were evaluated during berry ripening. The grapevines trained in VSP had higher water status as compared to GDC, shown by differences in pre-dawn leaf water potential (ψpd) and stem water potential (ψstem). However, the CO2 assimilation was similar in both training systems. Fruit exposure was higher in VSP than in GDC, which contributed to increasing berry temperature. At harvest, the berries in GDC reached values near to 23 ºBrix whereas berries in VSP showed values near 21 ºBrix
