A study of factors contributing to late submission of course work

This case study uses log-linear modelling to investigate the interrelationships between factors that may contribute to the late submission of coursework by undergraduate students. A class of 86 computing students are considered. These students were exposed to traditional teaching methods supported by e-learning via a Managed Learning Environment (MLE). The MLE warehouses detailed data about student usage of the various areas of the environment, which can be used to interpret the approach taken to learning. The study investigates the interrelationship between these factors with the information as to whether the student handed in their course work on time or whether they were late. The results from the log-linear modelling technique show that there is an interaction between participating in Discussions within the MLE and the timely submission of course work, indicating that participants are more likely to hand in on time, than those students who do not participate.

Comovement in UK real estate sector returns

Engle et al. (1990) distinguish between 'heat waves' and 'meteor showers' in an analogy which tries to differentiate between particular effects, not transmitted among markets, and general effects, which tend to affect all the markets, although different markets can be affected to different degrees. This paper applies this approach to the study of the monthly returns of four real estate market sectors: Office, Retail, Industrial and Retail Warehouses in the UK over the period 1979:2 to 1997:12. A VAR methodology used with the aim of detecting the causal relations and dynamic interactions among sector returns, as well as the transmission mechanisms of their information flows. The results obtained permit us to conclude that there is a good deal of integration between the monthly return time series for all the sectors. Therefore, diversification across real estate market sectors does not allow for the reduction of risk without sacrificing expected returns.

Grid computing solutions for distributed repositories of protein folding and unfolding simulations

The P-found protein folding and unfolding simulation repository is designed to allow scientists to perform analyses across large, distributed simulation data sets. There are two storage components in P-found: a primary repository of simulation data and a data warehouse. Here we demonstrate how grid technologies can support multiple, distributed P-found installations. In particular we look at two aspects, first how grid data management technologies can be used to access the distributed data warehouses; and secondly, how the grid can be used to transfer analysis programs to the primary repositories --- this is an important and challenging aspect of P-found because the data volumes involved are too large to be centralised. The grid technologies we are developing with the P-found system will allow new large data sets of protein folding simulations to be accessed and analysed in novel ways, with significant potential for enabling new scientific discoveries.

P-found: grid-enabling distributed repositories of protein folding and unfolding simulations for data mining

The P-found protein folding and unfolding simulation repository is designed to allow scientists to perform data mining and other analyses across large, distributed simulation data sets. There are two storage components in P-found: a primary repository of simulation data that is used to populate the second component, and a data warehouse that contains important molecular properties. These properties may be used for data mining studies. Here we demonstrate how grid technologies can support multiple, distributed P-found installations. In particular, we look at two aspects: firstly, how grid data management technologies can be used to access the distributed data warehouses; and secondly, how the grid can be used to transfer analysis programs to the primary repositories — this is an important and challenging aspect of P-found, due to the large data volumes involved and the desire of scientists to maintain control of their own data. The grid technologies we are developing with the P-found system will allow new large data sets of protein folding simulations to be accessed and analysed in novel ways, with significant potential for enabling scientific discovery.

Treating the Tenant as a Customer: can good service improve real estate performance?

Customer Relationship Management (CRM) theory suggests that good customer service results in satisfied customers, who in turn are more likely to remain loyal and recommend the service provider to others. Applied to real estate, this theory implies that landlords should see a return on any investment in the service they give to tenants, in the form of increased lease renewal rates and fewer void periods, achieved without compromising rents. This paper examines determinants of occupier satisfaction, and investigates the relationship between occupier satisfaction and property performance, using measures such as capital growth, income return, lease renewal rates and total return. The analysis is based upon a pilot study using occupier satisfaction responses from around 2500 interviewees based in multi-tenanted offices, shopping centres and retail warehouses on out-of-town retail parks in the UK. The analysis is being extended to cover a larger sample for the author’s PhD. Part 1 of the analysis examines occupier satisfaction, whilst Part 2 considers its impact on property performance.

A utilização dos fundos de investimento imobiliários como veículos na gestão de ativos das empresas

No Brasil, historicamente, as companhias sempre detiveram ativos imobiliários (sede social, plantas fabris, galpões, etc.), influenciadas pela instabilidade macroeconômica, o que acarretava a dificuldade em estimar o preço do dinheiro. Com o controle inflacionário, foi possível expandir formas de financiamento de longo prazo, permitindo que as empresas passassem a realizar a alocação de recursos financeiros com mais eficiência, direcionando-os para as suas atividades principais. Assim, a discussão sobre a propriedade imobiliária pelas empresas é recente. E, há menos tempo ainda é que foram elaboradas novas alternativas, como os fundos de investimento imobiliário que tornaram-se mais representativos nos últimos três anos. Este trabalho visa analisar sobre as razões que permitem aos fundos de investimento imobiliário serem propostos como uma opção para as empresas realizarem a gestão de seus ativos imobiliários, quando estas buscarem não imobilizar recursos, mas sim, a locação do imóvel. Para alcançar este objetivo, o trabalho fará uma abordagem qualitativa, apresentando as características operacionais e tributárias dos fundos imobiliários e dois estudos de casos de empresas que promoveram a desmobilização de ativos por meio de fundos imobiliários. O primeiro caso é a venda de um centro de distribuição do Magazine Luiza, uma das maiores redes varejistas no Brasil, para o fundo Kinea Renda Imobiliária. O segundo exemplo é o processo de desmobilização do Banco do Brasil e o desenvolvimento do fundo BB Progressivo II. Será verificado que os objetivos das empresas foram alcançados nos dois casos e que, de fato, os fundos imobiliários podem ser considerados como uma alternativa. Entretanto, não é possível a conclusão de que ele produza os melhores resultados e que exista alguma atividade empresarial que tenha maior propensão a sua utilização. A pesquisa aborda os fundos de investimento imobiliário com o foco no locatário e possibilita que sejam aprimorados estudos quantitativos, identificando reações do mercado brasileiro ao aumento na quantidade de operações, e outras pesquisas qualitativas que envolvam novas estruturas de financiamento.

Qualidade de frutos de cajá-manga armazenados sob diferentes temperaturas

O presente trabalho teve como objetivo determinar o efeito de diferentes temperaturas de armazenamento na qualidade de frutos de cajá-manga. Os frutos de cajá-manga foram obtidos junto ao CEAGESP - Companhia de Entrepostos e Armazéns Gerais de São Paulo, e transportados em caixas isotérmicas para o Laboratório onde foram selecionados quanto à aparência, estádio de maturação, ausência de danos físicos, depois sanitizados em solução de 50 ppm de cloro livre e acondicionados em bandejas de poliestireno expandido, envolto por filme de policloreto de vinila (PVC). O delineamento experimental utilizado foi o inteiramente casualizado, com três tratamentos (4ºC, 8ºC e 25ºC) e 5 épocas de avaliação (0; 3; 6; 9 e 12 dias após a instalação do experimento). em cada coleta, foram avaliadas a firmeza, a acidez titulável, os sólidos solúveis, o teor de ácido ascórbico, a cor da casca e, também, a liberação de CO2 pelos frutos ao longo do tempo. Foi observado que baixas temperaturas prolongam a vida útil dos frutos e que a temperatura de armazenamento influencia nas características avaliadas, sendo a temperatura de 8ºC a mais adequada para o armazenamento dos frutos de cajá-manga.

Vicus Judæorum: os judeus e o espaço urbano no Recife neerlandês

This work broaches the participation of the Jewish community in the urban expansion of Recife, Brazil, during the Dutch period (1630-1654). With the arrival of the Dutch, the village of Olinda, former capital of Pernambuco, was destroyed and Recife received the juridical statute of city (stad), becoming the capital of Dutch Brazil or New Holland. It became the main West Indians Company s entrepot in South Atlantic, serving as naval base, port of call for ships, and point of export of the sugar production of Pernambuco, and import of European goods and African slaves. In order to such administrative, military and economic functions be carried out, the sand isthmus where Recife used to stay, and the fluvial island of Antônio Vaz, received improvements of many sort. The Dutch hydraulic technology was put in practice, with a posture of opposition between civilization and nature. Among military works and production of urban equipments, the rivers shores were land-filled, canals were built, bridges were lifted, and hundreds of buildings were erected. The civil Dutch population of Recife engaged in the process of production of physical space, which brought a sense of collective action towards the formation of the urban, or burgher, community. From the physical to the social space, there was an effort towards Dutch cultural standards in the urban environment. The Zur Israel Jewish community, formed by private civilians, it is, nonemployees of the WIC, engaged in those processes. It produced physical space through the land-filling and improvement of non healthy areas, and was also responsible for the construction of a significant section of the town s buildings and some of urban equipments, such as stores, markets and slave-warehouses, making more dynamic their economical activities. But their social traffic was due to the adaptation of their behavior to the standards of Dutch sociability. Thus, the community body made itself part of the social body. Disposing of internal selfregulation, it produced spaces with their cultural references cemetery, synagogue, texts enjoying benefits of the government. Zur Israel inscribed itself in the universal history of the Jews as the first community of Americas, and had a fundamental part on the emancipation of Jews within Western society

Feira livre de Macaíba/RN : um estudo das modificações na dinâmica socioespacial (1960/2006)

The objective of the current piece of research is to reflect upon the diverse changes that have occurred in the social and spatial dynamics of the Macaíba fair in the period between 1960 and 2006. During the second half of the 19th century, Macaíba had in the commerce one of this principle economic base a contribution for which the city became one of the main commercial warehouses of the East coast of the Rio Grande do Norte region. This helped lead to the growth of Macaíba s fair, which proved to be one of the most important existing in the state until the 1970 s. In the last two decades of the 20th century, certain elements represented challenges to the fair at Macaíba. These challenges stimulated substantial changes in the fair s dynamics which include the growth and expansion of the commercial and service sector, primarily though supermarkets; consolidation among the commercial and distribution networks, represented by the Central Office of Supply of the Rio Grande do Norte S/A (Ceasa/RN), by the wholesale and refrigeration companies; and the modernization of transportation methods, which permitted an expanded reach for these networks. Even with all these changes, the fair continues to be one of the strongest aspects of the city being the center of resistance against the surge of new forms of commerce and consumption in the city (notable the supermarkets) and the diffusion of other aspects of globalization. The fair has economic importance, as it offers a popular marketplace for the commercialization of very different products and a means for supplying goods to the residents of the city and the rural communities of Macaíba and the surrounding municipalities; and socio-cultural importance in that the fair is a place where popular tradition is expressed, a place where a great number of parallel activities occur, a place for meeting again and again, of conversations, of manifestations of culture and art, and of socialization in all of its dimensions

Comercialização de caju in natura na região noroeste do estado de São Paulo

Para estimar e analisar os custos de comercialização e identificar locais e formas de comercialização do caju, foram realizadas, durante o ano de 2000/01, entrevistas com produtores, técnicos da extensão rural, agentes intermediários e pesquisadores de órgãos públicos. Também foram levantadas informações na Companhia de Entrepostos e Armazéns Gerais de São Paulo (CEAGESP). Os custos agregados pelo segmento da comercialização devem-se, em grande parte, às despesas com o transporte até os grandes centros atacadistas, e também à comissão definida pelo atacadista. Para o produtor da região Noroeste do Estado de São Paulo, o ideal seria direcionar sua produção para os meses de janeiro a junho, garantindo assim melhores preços e com isso resultados mais satisfatórios.

Metrics to support the evaluation of association rule clustering

Many topics related to association mining have received attention in the research community, especially the ones focused on the discovery of interesting knowledge. A promising approach, related to this topic, is the application of clustering in the pre-processing step to aid the user to find the relevant associative patterns of the domain. In this paper, we propose nine metrics to support the evaluation of this kind of approach. The metrics are important since they provide criteria to: (a) analyze the methodologies, (b) identify their positive and negative aspects, (c) carry out comparisons among them and, therefore, (d) help the users to select the most suitable solution for their problems. Some experiments were done in order to present how the metrics can be used and their usefulness. © 2013 Springer-Verlag GmbH.
