Key performance indicators and the balanced scorecard at the Luxury Brand Hotels of Pestana Group

Traditional approaches to evaluate performance in hotels, have mainly used financial measures. Building on Speckbacher et al. (2003), this Work Project aims to design and propose a Balanced Scorecard Type II as a performance measurement/management system for the hospitality industry based on data collected at the Luxury Brand Hotels of Pestana Group. The main contribution is to better align the vision, strategy and financial and non-financial performance measures in this category of hotels, in particular those of Pestana Group, and by doing so, lead their managers to focus on what is really critical and, consequently improve the overall performance.

Protocol for the psychotherapeutic group intervention for facilitating posttraumatic growth in nonmetastatic breast cancer patients

Breast cancer can be perceived as a traumatic event with disturbing effects on psychological domains such as depression, anxiety, and Posttraumatic Stress Disorder. In contrast, growing evidence has shown that posttraumatic growth can occur as a result of coping with breast cancer. Challenging the assumptive world, deliberate rumination, and emotional disclosure are recognized as strong predictors of posttraumatic growth. Group interventions may also increase social support, distress disclosure, and posttraumatic growth. The aim of this study is to evaluate how group-based interventions can facilitate posttraumatic growth and promote improved psychosocial adjustment to breast cancer. This article describes the study protocol and the applied research methods.

Molecular characterization of group A rotavirus before and after the introduction of vaccines in Brazil

ABSTRACTINTRODUCTION:In this study, the molecular characteristics of group A rotavirus (RVA) were compared in samples obtained before and after RVA vaccine-introduction in Brazil.METHODS:Eighty samples were screened for the presence of RVA. Positive samples were molecularly analyzed.RESULTS:RVA positivity was 16.9%, with a predominance of G2P[4]. Periods: pre-vaccination: predominance of IId (G1), IId (G2) lineages, and I1 and E1 genotypes; post-vaccination: predominance of Ib (G1), IIa, and IIc (G2) lineages and I2 and E2 genotypes.CONCLUSIONS:Although changes in RVA-circulation pattern were observed in the post-vaccination period, it could not be attributed to vaccination process.

Cerebral vasculopathy in children with sickle cell disease A study of genetic modulators of the disease

Sickle cell disease (SCD) is a genetic disorder with recessive transmission, caused by the mutation HBB:c.20A>T. It originates hemoglobin S that forms polymers inside the erythrocyte, upon deoxygenation, deforming it and ultimately leading to premature hemolysis. The disease presents with high heterogeneity of clinical manifestations, the most devastating of which, ischemic stroke, occurs in 11% of patients until 20 years of age. In this study, we tried to identify genetic modifiers of risk and episodes of stroke by studying 66 children with SCD, grouped according to the degree of cerebral vasculopathy (Stroke, Risk and Control). Association studies were performed between the three phenotypic groups and hematological and biochemical parameters of patients, as well as with 23 polymorphic regions in genes related to vascular cell adhesion (VCAM-1, THBS-1 and CD36), vascular tonus (NOS3 and ET-1) and inflammation (TNF-α and HMOX-1). Relevant data was collected from patient’s medical records. Known genetic modulators of SCD (beta-globin cluster haplotype and HBA and BCL11A genotypes) and putative genetic modifiers of cerebral vasculopathy were characterized. Differences in their distribution among groups were assessed. VCAM-1 rs1409419 allele C and NOS3 rs207044 allele C were associated to stroke events, while VCAM-1 rs1409419 allele T was found to be protective. Alleles 4a and 4b of NOS3 27 bp VNTR appeared to be respectively associated to stroke risk and protection. HMOX-1 longer STRs seemed to predispose to stroke. Higher hemoglobin F levels were found in Control group, as a result of Senegal haplotype or of BCL11A rs11886868 allele T, and higher lactate dehydrogenase levels, marker of hemolysis, were found in Risk group. Molecular mechanisms underlying the modifier functions of the relevant genetic variants are discussed.

Contributo para o estudo dos efeitos da passagem à situação (e idade) de reforma na frequência das principais doenças crónicas em Portugal

RESUMO - Introdução: A transição para a reforma é um acontecimento que pode acarretar alterações suscetíveis de afetar o estado de saúde. Vários estudos têm investigado os efeitos da reforma no estado de saúde, embora poucos o tenham investigado, especificamente, nas doenças crónicas. As recentes políticas de aumento da idade de reforma, assim como a ausência de consenso sobre os efeitos da reforma na saúde, atribuem-lhe ainda maior importância. Constituem objetivos do presente estudo quantificar a associação entre a Passagem à situação de reforma (e idade de reforma) e a frequência de cada uma das principais doenças crónicas, no sentido dos efeitos da reforma nestes indicadores de saúde (doença respiratória crónica, diabetes, doença cardiovascular, AVC, depressão e cancro). Material e Métodos: Desenvolveu-se um estudo transversal, no qual foram analisados os dados provenientes das amostras representativas da população portuguesa SHARE 2011 e ECOS 2013. As associações foram quantificadas através do cálculo do Odds ratio por Regressão Logística Binária com avaliação do confundimento e modificação de efeito. As variáveis de doença crónica foram medidas por auto-reporte. Foram considerados os reformados que se encontrassem em processo de reforma (ou seja, reformados há 5 anos ou menos) e que não se tivessem reformado por doença. Resultados: A reforma não se encontrou significativamente associada a nenhuma das doenças crónicas consideradas, excetuando-se: i) o cancro (na amostra ECOS), para o qual foi fator protetor; ii) e a doença cardiovascular (na amostra SHARE), para a qual teve um efeito prejudicial, mas apenas em não hipertensos. A reforma em idade antecipada pareceu encontrar-se associada a um pior estado de saúde, relativamente à reforma em idade legal (ou após). Tal observou-se no Cancro (nas amostras ECOS e SHARE), na Diabetes (na amostra SHARE), e no AVC em pessoas sem Doença Cardiovascular (na amostra SHARE). Pelo contrário, em pessoas com Doença Cardiovascular a reforma antecipada pareceu constituir um fator protetor. Discussão e conclusões: As diferenças observadas nos resultados entre amostras poderão, entre outros, atribuir-se às diferentes populações em estudo, dimensões amostrais e desenhos de amostragem. Os resultados obtidos não são muito diferentes dos que têm sido descritos na bibliografia, ainda que haja um número reduzido de estudos sobre esta matéria. Indicam que, eventualmente, as recentes alterações de aumento da idade de reforma poderão expandir o grupo de pessoas que se reformam antecipadamente, podendo resultar, eventualmente, num aumento da prevalência de doenças crónicas na população portuguesa. Os mecanismos através dos quais a reforma poderá influenciar a ocorrência de doenças crónicas permanecem por explicar, embora os seus principais fatores de risco pareçam representar importantes modificadores de efeito.

What Fidelidade group should do to convey its human centric brand identity values to millennial insurance consumers

Companies are concerned in attracting and retaining Millennial consumers, especially if their relation with this target audience is weak. This happens in the insurance industry in Portugal and in Fidelidade group specifically. The aim of this study is to recommend a strategy for the insurance group to improve its relationship with these consumers, by conveying its human centric values. In order to address this goal, we developed a qualitative research. The main insight is that Millennials may perceive those values in the industry but do not associate them with insurance brands.

National suicide prevention strategy for Afghanistan (NSPS)

RESUMO: Do suicídio no Afeganistão é uma prioridade de saúde pública. O Afeganistão é um país de baixo rendimento, emergindo de três décadas de conflitos. Há uma alta prevalência de sofrimento psicológico, perturbações mentais e abuso de substâncias. Existem várias questões sociais, tais como, desequilíbrio/violência de género, pobreza, atitudes e costumes obsoletos, rápidas mudanças sócio-culturais, violação dos direitos humanos e especialmente dos direitos das mulheres e das crianças. Estes fatores de risco contribuem para o aumento da vulnerabilidade da população em relação ao suicídio. A relativa alta taxa de suicídio no Afeganistão é especialmente significativa comparada com as taxas baixas em todos os países islâmicos. Os estudos mostraram predominância de suicídio nas mulheres (95%) e em pessoas jovens. Existe, por isso, uma necessidade urgente do país ter uma estratégia de prevenção do suicídio. A estratégia foi desenvolvida pela criação de um grupo técnico/ de assessoria multi-sectorial de diferentes intervenientes tais como governo, ONGs, agências doadoras, as famílias das vítimas e outraas partes interessadas. A estratégia baseia-se os seguintes valores chave:, respeito pelas diversidades; sensibilidade para as questões sócio-cultura-religiosa e de género; promoção da dignidade da sociedade; respeito pelos direitos humanoss.. Os 'seis pontos estratégicos' são: envolvimento das principais partes interessadas e criação de colaboração intersectorial coordenada; fornecimento de cuidados às pessoas que fazem tentativas de suicídio e às suas famílias; melhoria dos serviços para pessoas com doença mental e problemas psicossociais; promover uma comunicação e imagem adequada dos comportamentos suicidas, pelos meios de comunicação; reduzir o acesso aos meios de suicídio e coligir informação sobre as taxas de suicídio, os fatores de risco, os fatores protetores e as intervenções eficazes. A estratégia nacional de prevenção do suicídio será inicialmente implementada por 5 anos, com uma avaliação anual do plano de acção para entender os seus pontos fortes e limitações. Recomendações e sugestões serão incorporadas nos próxima planos anuais para uma intervenção eficaz. Um sistema de monitorização irá medir o progresso na implementação da estratégia.-----------------------------ABSTRACT: Suicide in Afghanistan is a public health priority. Afghanistan is a low-income country, emerging from three decades of conflicts. There is high prevalence of mental distress, mental disorders and substance abuse. There are multiple social issues, such as gender imbalance/violence, poverty, obsolete attitudes and customs, rapid social-cultural changes, human right violations, and especially women and children rights. These risk factors contribute to increase the vulnerability of the population for suicide. The relative high rate of suicide in Afghanistan is especially significant as the rates are low in all Islamic countries. Research studies have shown predominance of suicide in women (95%) and in young age people. There is an urgent need for the country to have a suicide prevention strategy. The strategy has been developed by establishing a multi-sectoral technical/advisory group of different stakeholders from government, NGOs, donor agencies, victim’s families, and interested parties. The strategy is based on the following key values, namely, respect for diversities; sensitiveness to socio-culture-religious and gender issues; promotion of the society dignity and respect for the human rights of people. The six ‘Strategic directions’ are: involving key stakeholders and creating coordinated inter-sectoral collaboration; providing after care for people making a suicide attempt and their families; improving services for people with mental disorders and psycho-social problems; promoting the safe reporting and image of suicidal behaviour by media; reducing access to the means of suicide and gathering information about suicide rates, risk factor, protective factors and effective interventions. The National Suicide Prevention Strategy will be initially implemented for 5 years, with an annual evaluation of the action plan to understand the strengths and limitations. Recommendations and suggestions will be incorporated into the next annual plans for effective intervention. A monitoring framework will measure progress in implementing the strategy.

Determinants for the subcellular localization of the inner and outer spore coat hubs in Bacillus subtilis

Endospores, or spores for simplicity, are a highly resistant cell type produced by some bacterial species under adverse conditions. Two main protective layers contribute to the resilience of spores: the cortex, composed of peptidoglycan, and the outermost proteinaceous coat. In Bacillus subtilis, the coat comprises up to 80 different proteins, organized into four sublayers: the basement layer, the inner coat, the outer coat and the crust. These proteins are synthesized at different times during sporulation and deposited at the spore surface in multiple coordinated waves. Central to coat formation is a group of morphogenetic proteins that guide the assembly of the coat components. Targeting of the coat proteins to the surface of the developing spore is mainly controlled by the SpoIVA morphogenetic ATPase. In a second stage, the coat proteins fully encircle the spore, a process termed encasement that requires the morphogenetic protein SpoVID. Assembly of the inner coat requires SafA, whereas formation of the outer coat and the crust requires CotE. SafA interacts directly with the N terminus of SpoVID. (...)

Dynamic group formation in mobile computer supported collaborative learning environment

Forming suitable learning groups is one of the factors that determine the efficiency of collaborative learning activities. However, only a few studies were carried out to address this problem in the mobile learning environments. In this paper, we propose a new approach for an automatic, customized, and dynamic group formation in Mobile Computer Supported Collaborative Learning (MCSCL) contexts. The proposed solution is based on the combination of three types of grouping criteria: learner’s personal characteristics, learner’s behaviours, and context information. The instructors can freely select the type, the number, and the weight of grouping criteria, together with other settings such as the number, the size, and the type of learning groups (homogeneous or heterogeneous). Apart from a grouping mechanism, the proposed approach represents a flexible tool to control each learner, and to manage the learning processes from the beginning to the end of collaborative learning activities. In order to evaluate the quality of the implemented group formation algorithm, we compare its Average Intra-cluster Distance (AID) with the one of a random group formation method. The results show a higher effectiveness of the proposed algorithm in forming homogenous and heterogeneous groups compared to the random method.

Effects of forest structure components on the occurence, group size and density of groups of bare-face tamarin (Saguinus bicolor - primates: Callitrichinae) in Central Amazonia

This study analyzed the influence of forest structural components on the occurence, size and density of groups of Bare-face Tamarin (Saguinus bicolor) - the most threatened species in the Amazon - and produced the first map of distribution of groups in large-scale spatial within the area of continuous forest. Population censuses were conducted between November 2002 and July 2003, covering 6400 hectares in the Ducke Reserve, Manaus-AM, Brazil. Groups of S. bicolor were recorded 41 times accordingly distributed in the environments: plateau (20); slopes (12); and lowlands (09). The mean group size was 4.8 indiv./group, and ranged from 2 to 11 individuals. In the sites where the groups were recorded, and in an equivalent number of sites where no tamarins were found located at least 500 m from those where they had been recorded, we placed 50 m x 50 m plots to record the following forest structural components: abundance of trees; abundance of lianas; abundance of fruiting trees and lianas; abundance of snags; abundance of logs; percentage of canopy opening; leaf litter depth; and altitude. Bare-face Tamarin more often uses areas with lower abundance of forest logs, smaller canopy opening and with higher abundance of snags, areas in the forest with smaller canopy opening present higher density of S. bicolor groups. Apparently this species does not use the forest in a random way, and may select areas for its daily activities depending on the micro-environmental heterogeneity produced by the forest structural components.

Evidence for inter- and intra-species biofilm formation variability among a small group of coagulase-negative staphylococci

Coagulase-negative staphylococci (CoNS) are common bacterial colonisers of the human skin. They are often involved in nosocomial infections due to biofilm formation in indwelling medical devices. While biofilm formation has been extensively studied in Staphylococcus epidermidis, little is known regarding other CoNS species. Here, biofilms from six different CoNS species were characterised in terms of biofilm composition and architecture. Interestingly, the ability to form a thick biofilm was not associated with any particular species, and high variability on biofilm accumulation was found within the same species. Cell viability assays also revealed different proportions of live and dead cells within biofilms formed by different species, although this parameter was particularly similar at the intra-species level. On the other hand, biofilm disruption assays demonstrated important inter- and intra-species differences regarding extracellular matrix composition. Lastly, confocal laser scanning microscopy (CLSM) experiments confirmed this variability, highlighting important differences and common features of CoNS biofilms. We hypothesised that the biofilm formation heterogeneity observed was rather associated with biofilm matrix composition than with cells themselves. Additionally, our results indicate that polysaccharides, DNA and proteins are fundamental pieces in the process of CoNS biofilm formation.
