Facteurs environnementaux associés à un asthme mal maîtrisé chez les enfants montréalais

Problématique : Plusieurs expositions résidentielles ont été associées à la prévalence de l’asthme. Toutefois, peu d’études populationnelles ont examiné la relation entre ces facteurs et un asthme mal maîtrisé chez l’enfant. Objectif : Évaluer les facteurs environnementaux résidentiels associés à un asthme mal maîtrisé chez les enfants montréalais âgés de 6 mois à 12 ans. Méthodes : Les données sont tirées d’une enquête transversale menée en 2006 sur la santé respiratoire d’enfants montréalais âgés de 6 mois à 12 ans (n=7980). La maîtrise de l’asthme a été évaluée chez les enfants avec un asthme actif au cours de l’année précédent l’enquête (n=980) selon des critères recommandés par les lignes directrices canadiennes sur l’asthme. Les rapports de prévalence (RP) et les intervalles de confiance (IC) à 95 % caractérisant l’association entre les facteurs environnementaux, incluant la présence d’allergènes, d’irritants, d’humidité et de moisissures, et le risque d’un asthme mal maîtrisé ont été estimés à l’aide de modèles de régression log-binomiale. Les sujets avec une maîtrise acceptable de l’asthme ont été comparés à ceux dont la maladie était mal maîtrisée. Résultats : Des 980 enfants avec un asthme actif au cours de l’année précédant l’enquête, 36 % ont rencontré au moins un des critères des lignes directrices canadiennes suggérant un asthme mal maîtrisé. Les caractéristiques de la population associées à un asthme mal maîtrisé sont : un plus jeune âge, des antécédents d’atopie parentale, une faible scolarisation de la mère, une mère d’origine étrangère et le statut de locataire. Après ajustement pour l’âge de l’enfant, l’atopie parentale et l’exposition à la fumée de tabac au domicile, une intensité de trafic élevée à proximité du domicile (RP, 1,35; IC 95 %, 1,00-1,81) et la localisation au sous-sol de la chambre de l’enfant ou de sa résidence (RP 1,30; IC 95 %, 1,01-1,66) étaient associées à un risque accru d’asthme mal maîtrisé. Conclusions : Une maîtrise sous-optimale de l’asthme semble être associée à l’exposition au trafic routier et à des conditions d’humidité excessive et probablement de moisissures. Cette dernière exposition étant plus fréquente, elle a probablement un plus grand impact en matière de santé publique.

Re-thinking commercial real estate market segmentation

Investments in direct real estate are inherently difficult to segment compared to other asset classes due to the complex and heterogeneous nature of the asset. The most common segmentation in real estate investment analysis relies on property sector and geographical region. In this paper, we compare the predictive power of existing industry classifications with a new type of segmentation using cluster analysis on a number of relevant property attributes including the equivalent yield and size of the property as well as information on lease terms, number of tenants and tenant concentration. The new segments are shown to be distinct and relatively stable over time. In a second stage of the analysis, we test whether the newly generated segments are able to better predict the resulting financial performance of the assets than the old dichotomous segments. Applying both discriminant and neural network analysis we find mixed evidence for this hypothesis. Overall, we conclude from our analysis that each of the two approaches to segmenting the market has its strengths and weaknesses so that both might be applied gainfully in real estate investment analysis and fund management.

Uso múltiplo dos recursos naturais da várzea por camponeses no Baixo Amazonas

A estratégia do uso múltiplo dos recursos naturais da várzea no Baixo Amazonas tem sofrido constante ameaça principalmente nos últimos 70 anos, devido a pressões resultantes das mudanças no mercado regional, como os cultivos comerciais, da intensificação da pesca comercial e da expansão da criação extensiva de gado e búfalo. Frente a esta problemática, a tese objetivou analisar as respostas de adaptação dos camponeses ao ambiente de várzea de acordo ao acesso ao fator de produção terra, às influências do ambiente e da paisagem, e a sua inserção ao mercado, na várzea do Baixo Amazonas, Santarém, no período de 1941 a 2002. Conhecer as respostas de adaptação das comunidades camponesas nos momentos de tensão é de extrema importância para o ecossistema da várzea, detectar alterações na estratégia do uso múltiplo dos recursos naturais. Os dados foram coletados em duas comunidades camponesas na várzea pertencentes a sub-região do Urucurituba, mesoregião do Baixo Amazonas, microregião de Santarém na região oeste do estado do Pará. As comunidades de Piracãoera de Cima e Piracãoera de Baixo foram selecionadas por possuirem uma alta restinga; estarem relativamente próximas ao centro urbano de Santarém, e produzirem culturas anuais em sistema intensivo, evidenciado em pesquisa anterior. Foram constituídos dois grupos de famílias camponesas de acordo com o acesso a terra, as Não- Arrendatárias e os Arrendatárias. A amostra composta de 57 famílias, correspondeu a 36% do total da população das duas comunidades. De acordo com este processo, a amostra foi constituída por 31 famílias Não-Arrendatários, e 26 Arrendatárias. Para aprofundar a análise procedeu-se a estratificar das famílias por sistemas de produção. Foram denominados sistemas de produção A, B e C, as quais apresentavam as seguintes características: O Sistema de Produção A prioriza a criação animal, médios e grandes animais, dentre o uso múltiplo dos recursos; o Sistema de Produção B: prioriza a agricultura, dentre o uso múltiplo. Neste sistema considera as famílias que criam, ou não, o gado bovino, e o Sistema de Produção C que prioriza a pesca, e a agricultura em menor proporção.Embasado no método participativo, as entrevistas as famílias foram realizadas com o auxílio de um questionário previamente estruturado e testado pelo IPAM/Santarém, com adaptações propostas por Costa (1995) para reconstituir historicamente a agricultura, a pesca, a criação de grandes animais, e o pomar caseiro. Após analisar as informações obtidas procedeu-se a Análise da Intensificação Agrícola, da eficiência Agrícola e a da eficiência dos sistemas de produção A, B e C nos dois grupos de camponeses concluímos que: A restrição ao fator de produção terra não condicionou a que os camponeses usassem mais intensivamente a terra. As famílias que arrendam terra não possuem sistemas agrícolas mais intensivos. A intensificação agrícola não influenciou negativamente na produtividade agrícola ao longo do tempo, não influenciou na eficiência dos sistemas de produção, nem tão pouco no uso múltiplo dos recursos. A intensificação da agricultura não influenciou o uso múltiplo dos recursos, porém, houve um redirecionamento da força de trabalho, entre a pesca e agricultura, principais atividades produtivas, para manter a unidade produtiva em funcionamento. Uma atividade libera mão-de-obra como uma forma de investimento a outra atividade. Os recursos financeiros obtidos na pesca ajudam na aquisição dos elementos de capital necessários para a atividade agrícola, e a adquirir os produtos industrializados no mercado para a família. Por outro lado, a renda proveniente da agricultura financia a pesca no verão e no inverno com a aquisição de gelo, alimentos para as viagens na pesca. Até iniciar a produção agrícola, a pesca mantém a família com a aquisição de produtos para serem consumidos, e a adquirir os elementos de capital. Em síntese, concluímos que os campesinos da várzea do Baixo Amazonas seguem a lógica do lucro, ao mesmo tempo se resguardando de fracassos por meio do uso múltiplo dos recursos através da diversificação de atividades e produtos.

Integrated pest management in multi-story public housing for the elderly in Houston, Texas

Integrated pest management is a viable alternative to traditional pest control methods. A paired sample design was utilized to measure the effect of IPM education on the number of cockroaches in a 200 unit, seven story public housing building for the elderly in Houston, TX. Glue traps were placed in 71 randomly selected apartments (5traps/unit) and left in place for two nights. Baseline cockroach counts were shared with the property manager, maintenance/janitorial staff, service coordinator, pest control professional and tenant representatives at the end of a one day “Integrated Pest Management in Multi-Family Housing” training course.^ There was a significant decrease in the average number of cockroaches after IPM education and implementation of IPM principles (P < 0.0003). Positive changes in behavior by members of the IPM team and changes in the housing authority operational plan were also found. Paired t-tests comparing the difference between mean cockroach counts at baseline and follow-up by location within the apartment all demonstrated a significant decrease in the number of cockroaches.^ Results supported the premise that IPM education and the implementation of IPM principles are effective measures to change pest control behaviors and control cockroaches. Cockroach infestations in multi-story housing are not solely determined by the actions of individual tenants. The actions of other residents, property managers and pest control professionals are also important factors in pest control.^ Findings support the implementation of IPM education and the adoption of IPM practices by public housing authorities. This study adds to existing evidence that clear communication of policies, a team approach and a commitment to ongoing inspection and monitoring of pests combined with corrective action to eliminate food, water and harborage and the judicial use of low risk pesticides have the potential to improve the living conditions of elderly residents living in public housing.^

Regional differences regarding land tenancy in rural Rwanda, with special reference to sharecropping in a coffee production area

This paper examines land tenancy systems and tenant contracts in Rwanda, with respect to socioeconomic contexts. Our research in southern and eastern Rwanda produced data suggesting that land borrowing with fixed rents has been generally practiced, and that rent levels have been low in comparison to expected revenues from field production. In the western areas of coffee production, however, the practice of sharecropping has recently appeared. This system is advantageous to landowners, as they are able to acquire half of the harvests; in addition, the fixed rent levels in this region are much higher than those of other regions. In the southern and eastern regions, because land borrowing with fixed rents has been the only tenancy pattern and rent levels have remained low, the economic situation should be interpreted in the context of a continuing traditional Rwandan land tenure system. In contrast, in the western coffee production area, the soaring of fixed rents and the emergence of sharecropping have been brought about by high pressures for land use, which were caused not only by a population increase but also by the development of cash crop production and the existence of a labor exchange system. The increase in rent levels has therefore been offset by a corresponding increase in agricultural productivity.

A comparison of security of tenure in Queensland and in Western Europe

Queensland residential tenancies are usually granted for up to 12 months with no guarantee of renewal. On expiration of the term, the landlord, without need to provide an explanation, can require the tenant to leave. Europeans find this unusual. As Hammar observes, to ‘never be sure whether ... you will be allowed to stay for another year ... is ok for a student, or for someone working ... but not for households’. This article informs Queensland policy makers and industry about European practices and concludes by proposing legislative amendments to realise the tenant’s security of tenure.

Learnings, case studies and guidelines for establishing shared and collaborative service delivery in the non-government sector: Evaluation of the Multi-Tenant Service Centre (MTSC) Pilots Project

This report presents learnings, case studies, guidelines and resources for non-government organisations that are planning to implement shared or collaborative arrangements with other agencies. It summarises results from an evaluation of the implementation phase of the Multi-Tenant Service Centre (MTSC) Pilots Project, which was completed in June 2008. This evaluation shows that developing and implementing shared and collaborative arrangements is a complex process that presents many risks, challenges and barriers to success, but can have many potential benefits for non government organisations. As this report makes clear, there is no ‘one size fits all’ approach to this process. The MTSC Pilots Project was conducted by the Department of Communities (DoC), Queensland Government, as part of its Strengthening Non-Government Organisations strategy. The objective of the MTSC Pilots initiative was to co-locate separate service providers in an appropriately located centre, operating with effective and transparent management, which enabled service providers to improve client services. Three MTSC consortiums in Mackay, Caboolture and Toowoomba were selected as the pilots over a four year period from 2006 – 2010.

Tenant Right and Agrarian Society in Ulster 1600-1870

The book has been described by various Irish historians as "the definitive treatment of that most peculiar institution--the Ulster Custom--and its tangled relationship with irish land and politics" (Liam Kennedy), "a brilliantly reconceptualised sketch of the Irish land question" (David Miller). "All previous discussion," according to another reviewer, "must take second place to Dowling's exhaustive survey, which draws on the whole range of surviving estate records to examine the theory and practice of tenant right across three centuries" (Sean Connolly).

Famine and land, 1845-80

While historians once tended to displace the Famine from a pivotal position in modern Irish history, more recent research emphasizes its centrality, and focuses upon the controversial issue of state responsibility. Mortality levels from the Famine place it, proportionately, as one of the most devastating recorded human catastrophes. Official British policy towards Ireland spanned two governments, those of Robert Peel and John Russell, with historians taking a more emollient view of the former: in fact there were significant continuities between the two. The legacy of the Famine was uneven, with commercial and technological advance and the consolidation of both the farming interest and landlordism. On the other hand, recent research emphasizes evidence of continuing economic uncertainty, particularly in the West, together with ongoing landlord-tenant tensions. Rural insecurities, crystallized by the poor harvests of 185964, underlay the post-Famine years, and fed into the politicization of the later 1870s.

The child and the letter: Anne Brontë’s The Tenant of Wildfell Hall

This essay engages with the question of childhood in Anne Brontë’s The Tenant of Wildfell Hall. Despite narrating a conflict concerning child custody, childhood is a subject rarely broached by the critics of the text. Indeed, the only instance of the child being addressed in criticism grants it the power to enclose potentially subversive narrative. This is a function attributed to the framing structure of the novel by other critics. This essay returns the child to Brontë’s text as a disruptive rather than containing force. Through a detailed close analysis of the novel I track such disruptions, and the extent to which these point to wider theoretical or methodological difficulties in critical accounts of childhood and absence in literature. The essay makes interventions into psychoanalysis, childhood studies, and the discourse of ‘framing’ within C19th literature.
