Partial utility-driven scheduling for flexible SLA and pricing arbitration in clouds

Cloud SLAs compensate customers with credits when average availability drops below certain levels. This is too inflexible because consumers lose non-measurable amounts of performance being only compensated later, in next charging cycles. We propose to schedule virtual machines (VMs), driven by range-based non-linear reductions of utility, different for classes of users and across different ranges of resource allocations: partial utility. This customer-defined metric, allows providers transferring resources between VMs in meaningful and economically efficient ways. We define a comprehensive cost model incorporating partial utility given by clients to a certain level of degradation, when VMs are allocated in overcommitted environments (Public, Private, Community Clouds). CloudSim was extended to support our scheduling model. Several simulation scenarios with synthetic and real workloads are presented, using datacenters with different dimensions regarding the number of servers and computational capacity. We show the partial utility-driven driven scheduling allows more VMs to be allocated. It brings benefits to providers, regarding revenue and resource utilization, allowing for more revenue per resource allocated and scaling well with the size of datacenters when comparing with an utility-oblivious redistribution of resources. Regarding clients, their workloads’ execution time is also improved, by incorporating an SLA-based redistribution of their VM’s computational power.

Healthcare-associated infections: challenges to public health in Brazil

This study presents a critical evaluation of the scientific literature related to this subject, aiming to assess the policies and administrative issues regarding the prevention and magnitude of healthcare-associated infections and discuss the challenges for their prevention in Brazil. The topics discussed included historical and administrative issues, challenges imposed by the characteristics of the healthcare system and the territorial dimension, laboratorial support limitations, costs, institutional culture, professional qualification, and patient engagement. It is urgent to hold a nationwide discussion among government representatives, institutions, and healthcare workers and users to overcome these challenges.

Performance evaluation of hospitals that provide care in the public health system, Brazil

OBJECTIVE To analyze if size, administrative level, legal status, type of unit and educational activity influence the hospital network performance in providing services to the Brazilian Unified Health System.METHODS This cross-sectional study evaluated data from the Hospital Information System and the Cadastro Nacional de Estabelecimentos de Saúde (National Registry of Health Facilities), 2012, in Sao Paulo, Southeastern Brazil. We calculated performance indicators, such as: the ratio of hospital employees per bed; mean amount paid for admission; bed occupancy rate; average length of stay; bed turnover index and hospital mortality rate. Data were expressed as mean and standard deviation. The groups were compared using analysis of variance (ANOVA) and Bonferroni correction.RESULTS The hospital occupancy rate in small hospitals was lower than in medium, big and special-sized hospitals. Higher hospital occupancy rate and bed turnover index were observed in hospitals that include education in their activities. The hospital mortality rate was lower in specialized hospitals compared to general ones, despite their higher proportion of highly complex admissions. We found no differences between hospitals in the direct and indirect administration for most of the indicators analyzed.CONCLUSIONS The study indicated the importance of the scale effect on efficiency, and larger hospitals had a higher performance. Hospitals that include education in their activities had a higher operating performance, albeit with associated importance of using human resources and highly complex structures. Specialized hospitals had a significantly lower rate of mortality than general hospitals, indicating the positive effect of the volume of procedures and technology used on clinical outcomes. The analysis related to the administrative level and legal status did not show any significant performance differences between the categories of public hospitals.

A satisfação dos trabalhadores com as práticas de gestão de recursos humanos: o caso de uma Instituição do Ensino Superior Público em Portugal

Este estudo tem como objetivos: (1) conhecer as práticas desenvolvidas numa organização do Ensino Superior Público Português; (2) conhecer a tipologia das práticas de GRH de cariz tradicional e de cariz estratégico; (3) perceber em que medida as práticas de GRH estão relacionadas com a área de qualificação dos responsáveis do departamento de RH; (4) averiguar o grau de satisfação que os trabalhadores sentem com as Práticas de Gestão de Recursos Humanos desenvolvidas e a sua relação com a área de qualificação dos responsáveis do departamento de RH. Foi utilizada uma metodologia mista, que possibilita ampliar a obtenção de resultados em abordagens investigativas, proporcionando ganhos relevantes para a pesquisa. É realizado um primeiro estudo exploratório, que utiliza uma metodologia mista quantitativa e qualitativa, com recurso a uma entrevista semiestruturada e inquérito realizados aos responsáveis de RH, e que tem como objetivos identificar e caracterizar as Práticas de GRH vigentes na Organização e, consequentemente, averiguar se se aproximam das designadas na literatura, assim como averiguar o grau de intervenção do DRH no desenvolvimento das PGRH e caraterizar o perfil do responsável de RH na Organização, averiguando se a área de formação de RH influencia as Práticas de GRH desenvolvidas. No segundo estudo, recorremos a uma metodologia quantitativa com recurso ao inquérito por questionário, aplicado aos trabalhadores que exercem funções a tempo integral, para averiguar o grau de satisfação dos trabalhadores em relação às Práticas de Gestão de Recursos Humanos. Na compilação dos dois estudos foi nosso objetivo obter respostas às questões que orientaram a nossa investigação. Na parte final da dissertação são discutidos os principais resultados obtidos e apresentadas as conclusões do estudo aqui levado a cabo. Os resultados sugerem que: 1) as PGRH existentes são essencialmente de cariz tradicional, em especial a gestão administrativa; 2) as PGRH predominantes são: o Planeamento de Recursos Humanos, a Análise e Descrição de Funções, o Recrutamento e Seleção, a Formação e Desenvolvimento, a Gestão Administrativa, a Comunicação e a Partilha de Informação, Ética e Deontologia e o Estatuto Disciplinar; 3) existe pouco recurso ao outsourcing para as PGRH; 4) o grau de intervenção DRH baseia-se em atividades de cariz mais administrativo; 5) as práticas tradicionais de RH são aquelas que requerem mais tempo ao DRH; 6) não existe relação entre o tipo de PGRH e a área de qualificação do responsável do DRH; 7) as PGRH são realizadas seguindo essencialmente as normas legais e regras rígidas da GRH na AP; 8) algumas PGRH não são entendidas em contexto da AP, como importantes pelos gestores, embora já sejam desenvolvidos alguns procedimentos dessas práticas; 9) a PGRH da formação e desenvolvimento não é corretamente desenvolvida e não dá cumprimento ao estipulado na lei; 10) a gestão de carreiras e o sistema de compensação e recompensas são entendidas como inexistentes, porque não existem promoções e progressões desde 2005; 11) a avaliação do desempenho é um sistema burocrático e ritualista com fins de promoção e compensação, sem efeitos práticos no momento atual, e que causa insatisfação e o sentimento de injustiça; 12) existem problemas de comunicação quanto a partilha e uniformização de procedimentos entre UO; 13) a satisfação dos trabalhadores é maior com as PGRH de tipo tradicional, nomeadamente na gestão administrativa, recrutamento e seleção, análise e descrição de funções, acolhimento, integração e socialização 14) a satisfação é menor na gestão de carreiras, no sistema de compensação e recompensas e na avaliação do desempenho; 15) quanto a relação entre o grau de satisfação e as características sócio demográficas e profissionais dos inquiridos, os casos com significância mostram que os trabalhadores com 10 ou mais anos de antiguidade tendem a sentir mais satisfação com as práticas em GRH; 16) existe mais satisfação dos trabalhadores das UO onde o responsável de DRH possui formação na área de RH.

A Directiva 2011-24-UE, relativa ao exercício dos direitos dos doentes em matéria de cuidados transfronteiriços : análise : potenciais repercussões no direito de acesso aos cuidados de saúde transfronteiriços em Portugal

RESUMO - 1. INTRODUÇÃO: Ao longo dos tempos, assistiu-se a um aumento da importância da Saúde Pública na Comunidade Europeia, mas só há relativamente pouco tempo teve o merecido lugar de destaque à luz da legislação comunitária. Neste contexto e com a adopção do Programa Europeu de Saúde Pública, surge a necessidade de actualizar o pensamento nesta área. Assim, é identificada uma oportunidade para formular uma estratégia, que seja passível de reduzir desigualdades e que também em compreenda as necessidades de saúde. Com o expandir da questão e com o propósito de reduzir as desigualdades, surge a Directiva 2011/24/UE, que visa regulamentar os direitos dos doentes em matéria de cuidados transfronteiriços. 2. OBJETIVO: Este trabalho apresenta como objetivo primordial analisar a Directiva 2011/24/UE, bem como a Lei n.º 52/2014, de 25 de Agosto, e identificar as principais barreiras, ao exercício do direito de acesso aos cuidados de saúde transfronteiriços, pelos beneficiários do SNS em Portugal, derivadas da aplicação de tais instrumentos legais. 3. METODOLOGIA: Foi utilizada uma abordagem analítica e documental, baseada na metodologia qualitativa. 4. CONCLUSÕES: As principais barreiras ao direito de acesso aos cuidados de saúde transfronteiriços, para os beneficiários do SNS em Portugal, são de ordem financeira, linguística e cultural, informacional, de mobilidade física, de proximidade geográfica, de carácter administrativo e de continuidade dos cuidados. A transposição da Directiva 2011/24/UE para o quadro jurídico português resulta essencialmente em iniquidades no âmbito do acesso aos cuidados de saúde transfronteiriços.

Successful prevention of the transmission of vancomycin-resistant enterococci in a Brazilian public teaching hospital

INTRODUCTION: Vancomycin-resistant enterococci (VRE) can colonize or cause infections in high-risk patients and contaminate the environment. Our objective was to describe theepidemiological investigation of an outbreak of VRE, the interventions made, and their impact on its control. METHODS: We conducted a retrospective, descriptive, non-comparative study by reviewing the charts of patients with a VRE-positive culture in the University Hospital of Campinas State University, comprising 380 beds, 40 of which were in intensive care units (ICUs), who were admitted from February 2008-January 2009. Interventions were divided into educational activity, reviewing the workflow processes, engineering measures, and administrative procedures. RESULTS: There were 150 patients, 139 (92.7%) colonized and 11 (7.3%) infected. Seventy-three percent were cared for in non-ICUs (p = 0.028). Infection was more frequent in patients with a central-line (p = 0.043), mechanical ventilation (p = 0.013), urinary catheter (p = 0.049), or surgical drain (p = 0.049). Vancomycin, metronidazole, ciprofloxacin, and third-generation cephalosporin were previously used by 47 (31.3%), 31 (20.7%), 24 (16%), and 24 (16%) patients, respectively. Death was more frequent in infected (73%) than in colonized (17%) patients (p < 0.001). After the interventions, the attack rate fell from 1.49 to 0.33 (p < 0.001). CONCLUSIONS: Classical risk factors for VRE colonization or infection, e.g., being cared for in an ICU and previous use of vancomycin, were not found in this study. The conjunction of an educational program, strict adhesion to contact precautions, and reinforcement of environmental cleaning were able to prevent the dissemination of VRE.

Relatório de estágio curricular realizado na Câmara Municipal de Lisboa

The experience of an internship is always considered an experience that should be enriching, a first contact with the employment world. The intention is to build a bridge between the theory and practice - applying what has been learnt throughout the course. Therefore, it was started a new learning phase that seeks to take advantage and obtain experiences useful for a professional life based in efficiency and efficacy. The curricular internship was carried out within the Masters in Public Law and held by Faculdade de Direito da Universidade Nova de Lisboa (FDUNL)(Law School Of University New Of Lisbon) in the Câmara Municipal de Lisboa (CML) (Lisbon's Town Hall), in the Departamento de Política de Solos e Valorização Patrimonial (DPSVP) (Soil Politics and Patrimonial Valuation Department) of the Direção Municipal de Planeamento, Reabilitação e Gestão Urbanística (Municipal Direction of Planning, Rehabilitation and Urban Management) between September and December 2013. Throughout this internship, several activities within the DPSVP were developed. In an early stage, there was a presentation of the organic structure of Lisbon's Town Hall, and the Department where I was going to do the internship, and its competencies. Therefore I acquired key concepts and researched jurisprudence and legislation needed to the analysis and understanding of the activities done in the internship. In a second stage, it was done the analysis and understanding of the division into lots administrative procedures, as well as the solving of the problems occurred throughout that analysis. Besides that, there was the need to help preparing some procedural acts to be applied regarding the Department competencies, namely within the alienation, procurement, encumbrance and rental of immovable assets owned by the Municipality of Lisbon.

A importância da Polícia Municipal na segurança

The challenge of this work is to assess the importance of the municipal police in improving the safety of citizens, if gauging from this reality through contributions from the Municipal Police Guimarães. The IV Constitutional Review in 1997, enabled the Portuguese municipalities creating administrative police bodies. These services, known as Municipal Police, have gradually come up in several municipalities. Currently the Municipal Police have their fundamental legal regulations of Law No. 19/2004 of 20 May, which, according to the Portuguese Constitution provides that these must be seen as municipal services, which act in a space territorially delimited, which corresponds to the municipality that each belongs. Under Article 237, paragraph 3, of the Constitution, the Municipal Police are municipal services, which shall cooperate in the maintenance of public order and protection of local communities, acting in cooperation with the security forces, public security functions. The safety concept has been taking an increasingly significant importance within the population. Is also no doubt say that, currently, insecurity affects all of society and is a major concern of law enforcement authorities. To find suitable answers we found that there are several studies on these subjects. In order to be able to make our contribution, text looks us on this subject, having had the support of the Municipal Police Guimarães, in the preparation of this work. Thus, based on a survey, they were sounded out, as privileged actors, agents of the Municipal Police Guimarães, in order to know their perceptions with regard to security issues faced in the context of security. We understand ask them to answer in particular the following questions: What are the most facilitators situations of crime? How important is the Municipal Police Guimarães in crime prevention? What are the strategies for prevention of incivilities? What other skills that can be conferred upon the Municipal Police? The results obtained allowed us to conclude that incivilities facilitate the occurrence of crimes and that the Municipal Police may have a more active role in the security of the population. If you were given other duties, in addition to that already have, the Municipal Police could reach another level of effectiveness. However we understand that any change to the tasks of this police need a serious and profound reflection, to find complementary alternatives with the security forces, which does not conflict with current assignments of any of the parties or with the interests of citizens.
