How does the use of different road networks effect the optimal location of facilities in rural areas?

The p-median problem is often used to locate P service facilities in a geographically distributed population. Important for the performance of such a model is the distance measure. Distance measure can vary if the accuracy of the road network varies. The rst aim in this study is to analyze how the optimal location solutions vary, using the p-median model, when the road network is alternated. It is hard to nd an exact optimal solution for p-median problems. Therefore, in this study two heuristic solutions are applied, simulating annealing and a classic heuristic. The secondary aim is to compare the optimal location solutions using dierent algorithms for large p-median problem. The investigation is conducted by the means of a case study in a rural region with an asymmetrically distributed population, Dalecarlia. The study shows that the use of more accurate road networks gives better solutions for optimal location, regardless what algorithm that is used and regardless how many service facilities that is optimized for. It is also shown that the simulated annealing algorithm not just is much faster than the classic heuristic used here, but also in most cases gives better location solutions.

Assessing the physical environment of older people’s residential care facilities: development of the Swedish version of the Sheffield Care Environment Assessment Matrix (S-SCEAM)

Background There is emerging evidence that the physical environment is important for health, quality of life and care, but there is a lack of valid instruments to assess health care environments. The Sheffield Care Environment Assessment Matrix (SCEAM), developed in the United Kingdom, provides a comprehensive assessment of the physical environment of residential care facilities for older people. This paper reports on the translation and adaptation of SCEAM for use in Swedish residential care facilities for older people, including information on its validity and reliability. Methods SCEAM was translated into Swedish and back-translated into English, and assessed for its relevance by experts using content validity index (CVI) together with qualitative data. After modification, the validity assessments were repeated and followed by test-retest and inter-rater reliability tests in six units within a Swedish residential care facility that varied in terms of their environmental characteristics. Results Translation and back translation identified linguistic and semantic related issues. The results of the first content validity analysis showed that more than one third of the items had item-CVI (I-CVI) values less than the critical value of 0.78.  After modifying the instrument, the second content validation analysis resulted in I-CVI scores above 0.78, the suggested criteria for excellent content validity. Test-retest reliability showed high stability (96% and 95% for two independent raters respectively), and inter-rater reliability demonstrated high levels of agreement (95% and 94% on two separate rating occasions). Kappa values were very good for test-retest (κ= 0.903 and 0.869) and inter-rater reliability (κ= 0.851 and 0.832). Conclusions Adapting an instrument to a domestic context is a complex and time-consuming process, requiring an understanding of the culture where the instrument was developed and where it is to be used. A team, including the instrument’s developers, translators, and researchers is necessary to ensure a valid translation and adaption. This study showed preliminary validity and reliability evidence for the Swedish version (S-SCEAM) when used in a Swedish context. Further, we believe that the S-SCEAM has improved compared to the original instrument and suggest that it can be used as a foundation for future developments of the SCEAM model.

Gestão de facilities : estudo exploratório da prática em empresas instaladas na região metropolitana de Porto Alegre

O fácil acesso às tecnologias prediais e o seu barateamento contribuíram para seu uso em grandes empresas que acreditam no retorno desse investimento através do aumento em sua produtividade e eficiência. Diante de um grande número de componentes tecnológicos na edificação, surge a necessidade de administrar e operar este novo ambiente construído, assegurando um perfeito funcionamento do edifício. Busca-se, portanto, destacar que esta sofisticação da edificação retrata ainda a imagem corporativa da empresa e sua gestão é responsabilidade de engenheiros e arquitetos. Para que esse ambiente funcione adequadamente, a gestão do edifício deve estar intimamente ligada ao planejamento estratégico da empresa, unindo forças para melhor servir a organização. O sucesso da função de gestão facilities depende da habilidade de identificar, comunicar e administrar oportunidades para ajudar a suportar os objetivos organizacionais. Um modelo eficiente de gestão deve contar com o apoio de um sistema de informação eficaz para agilizar a tomada de decisão como também armazenar dados de controle. A eficiência dos processos de planejamento estratégico e operacional depende mais da qualidade da informação utilizada do que dos próprios processos empregados para planejar. Novas soluções, que surgem no mercado internacional, ajudam os administradores organizacionais a solucionar os desafios diários de maximizar retornos no espaço físico organizacional. Uma investigação em um conjunto de empresa dos setores industrial, comercial e de serviços inseridas na região metropolitana de Porto Alegre é realizada a fim de conhecer o tipo de gestão do ambiente construído que acontece no Brasil e o entendimento por parte dos gestores de como melhorar a efetividade da organização através do ambiente construído A falta de um modelo de gestão da edificação na maioria destas empresas e de ferramentas que suportem esta atividade levam a acreditar que o Brasil deve evoluir na área de operação predial a fim de otimizar o espaço físico das organizações. O desconhecimento por partes dos gestores de que uma gestão estratégica pode agregar valor ao negócio das organizações foi outro aspecto observado, necessitando, portanto, uma maior interação entre gestores do ambiente construído.

Relacionamento com clientes no mercado de serviços : um estudo exploratório na atividade de facilities centers

A satisfação do cliente se apresenta como objeto de inúmeros estudos e pesquisas acadêmicas sobre o comportamento do consumidor muito em função da sua implicação gerencial direta para fidelização, retenção do cliente, estabelecimento de relações duradouras e a consequente sustentabilidade do negócio. Em função da experiência profissional do autor, essa dissertação compara as percepções de satisfação de lojistas de dois shopping centers com os respectivos serviços de facilities dada a decisão gerencial de terceirização ou internalização dessas atividades. Os dados coletados junto aos consumidores organizacionais através de entrevistas presenciais foram analisados com base estatística e os resultados mostram indícios de que essa opção gerencial tem significativa relevância na formação da satisfação do cliente. Além dessa conclusão principal, são oferecidas ainda discussões entre as perspectivas teóricas e os resultados da pesquisa de campo bem como possibilidades de aprofundamento do estudo. Por fim, apresentam-se algumas implicações e contribuições teóricas e gerenciais do presente estudo para acadêmicos e gestores de negócios, respectivamente.

Construction of facilities under asymmetric information: do constitutional constraints matter?

This paper studies construction of facilities in a federal state under asymmetric information. A country consists of two regions, each ruled by a local authority. The federal government plans to construct a facility in one of the regions. The facility generates a local value in the host region and has spillover effects in the other region. The federal government does not observe the local value because it is the local authority's private information. 80 the federal governrnent designs an incentive-compatible mechanism, specifying if the facility should be constructed and a balanced scheme of interregional transfers to finance its cost. The federal governrnent is constitutionally constrained to respect a given leveI of each region's welfare. We show that depending upon the facility's local value and the spillover effect, the governrnent faces different incentive problems. Moreover, their existence depends crucially on how stringent constitutional constraints are. Therefore, the optimal mechanism will also depend upon these three features of the model.

Prevalence of Toxoplasma gondii antibodies in ostriches (Struthio camelus) from commercial breeding facilities in the state of São Paulo, Brazil.

Toxoplasmosis is widespread zoonosis caused by Toxoplasma gondii,a protozoan that may infect mammals and birds. The aim of the present study was to assess the prevalence of T. gondii in ostriches (Struthio camelus) from commercial breeding facilities in the state of São Paulo, Brazil, in a way to increase the knowledge on the behavior and importance of the parasite in this animal species. A total of 195 serum samples were collected from ostriches from Sorocaba, Campinas, São Carlos, Aracatuba, São Paulo, Vale do Ribeira, Botucatu and sao Jose do Rio Preto, in the state of São Paulo. These samples were analyzed by means of the Modified Agglutination Test (MAT) in order to investigate the occurrence of Toxoplasmagondii antibodies. The test showed that 14.36% of the animals were seropositive to Toxoplasmagondii. Minimum titer was considered to be equal or greater than 1:16, and the greatest dilution observed was 1:16,384. No statistically significant differences were found between males and females. Seronegative animals occurred in only two regions (São Paulo and Sao Jose do Rio Preto). These results point out the importance of further studies on this infection in ostriches, and on management practices that may minimize the risk of toxoplasmosis transmission in these birds which would, in their turn, decrease the risk for the final consumer.

Seasonal variation of Alphitobius diaperinus population in broiler facilities in the center-north region of the state of São Paulo

The seasonality of Alphitobius diaperinus population was studied during different seasons during one year, in broiler facilities located in the center-north region of the State of São Paulo. Parasite counting was weekly carried out by the use of traps adapted from the modified model of Arends. During the experimental period, facilities were not submitted to chemical treatment, and the litter was changed between flocks. A lower number of adults and larvae was observed during autumn, with the peak registered in the summer. There was no significant difference between spring and winter averages (adults and larvae), and between spring and summer averages (adults). Average temperatures in the facilities varied from 23.4ºC (winter) to 27.1ºC (spring). The environmentally controlled systems used by the broiler industry provide an adequate habitat for A. diaperinus development. The continuous monitoring of the population of this parasite is essential for designing control strategies, and this can be accomplished by utilizing the traps used in the present experiment.

Two-level network design with intermediate facilities: An application to electrical distribution systems

We consider the two-level network design problem with intermediate facilities. This problem consists of designing a minimum cost network respecting some requirements, usually described in terms of the network topology or in terms of a desired flow of commodities between source and destination vertices. Each selected link must receive one of two types of edge facilities and the connection of different edge facilities requires a costly and capacitated vertex facility. We propose a hybrid decomposition approach which heuristically obtains tentative solutions for the vertex facilities number and location and use these solutions to limit the computational burden of a branch-and-cut algorithm. We test our method on instances of the power system secondary distribution network design problem. The results show that the method is efficient both in terms of solution quality and computational times. © 2010 Elsevier Ltd.
