Comparison of community structure of mangrove and riprap rock habitats along urban coastlines of south Florida

Globally, mangrove ecosystems have substantially declined, largely a result of human impacts. Mangroves provide a number of ecosystem services such as shoreline stabilization and nursery habitat for fish species. As declines continue, many of these ecosystem services are lost or altered. The need for shoreline stabilization has become increasingly apparent when chronic erosion wear away coastlines once mangroves are removed. Limestone boulders called riprap have been employed to offset continued erosion associated with mangrove clearing. In urban coastal areas adjacent to Biscayne Bay, Florida, as much as 80 percent of mangroves have been lost. More recently, riprap has been used in conjunction with mangroves to restore wetlands throughout the Bay. This riprap-mangrove habitat provides structure for marine organisms to colonize. However, fish assemblages and benthic composition could vary between this hybridized habitat and natural mangrove systems. Comparisons of fish and benthic community structure were made, to determine if abundance, species richness, and overall diversity differed between the two habitat types. Visual census and benthic quadrat surveys were conducted in vi mangrove and mangrove-riprap sites within two regions of Biscayne Bay. Total fish abundance was greater in mangroves, but the effect of habitat type on species richness varied between regions. The community structure of fishes and benthic composition differed significantly between mangroves and riprap habitats. Because species composition is so distinct, it is likely that the two communities do no function in the same manner. In areas with cleared shorelines, it may be important to consider the function of added anthropogenic structure for ecological communities.

Informal caregiving and mental ill health – differential relationships by workload, gender, age and area-remoteness in a UK region

Informal caregiving can be a demanding role which has been shown to impact on physical, psychological and social wellbeing. Methodological weaknesses including small sample sizes and subjective measures of mental health have led to inconclusive evidence about the relationship between informal caregiving and mental health. This paper reports on a study carried out in a UK region which investigated the relationship between informal caregiving and mental ill health. The analysis was conducted by linking three datasets, the Northern Ireland Longitudinal Study, the Northern Ireland Enhanced Prescribing Database and the Proximity to Service Index from the Northern Ireland Statistics and Research Agency. Our analysis used both a subjective measure of mental ill health, i.e. a question asked in the 2011 Census, and an objective measure, whether the respondents had been prescribed antidepressants by a General Practitioner between 2010 and 2012. We applied binary logistic multilevel modelling to these two responses to test whether, and for what sub-groups of the population, informal caregiving was related to mental ill health. The results showed that informal caregiving per se was not related to mental ill health although there was a strong relationship between the intensity of the caregiving role and mental ill health. Females under 50, who provided over 19 hours of care, were not employed or worked part-time and who provided care in both 2001 and 2011 were at a statistically significantly elevated risk of mental ill health. Caregivers in remote areas with limited access to shops and services were also at a significantly increased risk as evidenced by prescription rates for antidepressants. With community care policies aimed at supporting people to remain at home, the paper highlights the need for further research in order to target resources appropriately.

Health profile of centenarians in Portugal: a census-based approach

Background: The number of centenarians is rapidly increasing in Europe. In Portugal, it has almost tripled over the last 10 years and constitutes one of the fastest-growing segments of the population. This paper aims to describe the health and sociodemographic characteristics of Portuguese centenarians as given in the 2011 census and to identify sex differences. Methods: All persons living in Portugal mainland and Madeira and Azores islands aged 100 years old at the time of the 2011 census (N = 1,526) were considered. Measures include sociodemographic characteristics and perceived difficulties in six functional domains of basic actions (seeing, hearing, walking, cognition, self-care, and communication) as assessed by the Portuguese census official questionnaires. Results: Most centenarians are women (82.1 %), widowed (82 %), never attended school (51 %), and live in private households (71 %). The majority show major constraints in seeing (67.4 %), hearing (72.3 %), and particularly in their mobility (83.7 % cannot/have great difficulties in walking/climbing stairs and 80.7 % in bathing/dressing). In general, a better outcome was found for reported memory/concentration and understanding, with 39.1 % and 42.5 % presenting no or mild difficulty, respectively. Top-level functioning (no/mild difficulties in all dimensions concurrently) was observed in a minority of cases (5.96 %). Women outnumber men by a ratio of 4.6, and statistically significant differences were found between men and women for all health-related variables, with women presenting a higher percentage of difficulties. Conclusion: Portuguese centenarians experience great difficulties in sensory domains and basic daily living activities, and to a lesser extent in cognition and communication. The obtained profile, though self-reported, is important in considering the potential of social and family participation of this population regardless of their functional and sensory limitations. Based on the observed differences between men and women, gender-specific and gender-sensitive interventions are recommended in order to acknowledge women’s worse overall condition.

The high burden of injuries in South Africa

Objective To estimate the magnitude and characteristics of the injury burden in South Africa within a global context. Methods The Actuarial Society of South Africa demographic and AIDS model (ASSA 2002) – calibrated to survey, census and adjusted vital registration data – was used to calculate the total number of deaths in 2000. Causes of death were determined from the National Injury Mortality Surveillance System profile. Injury death rates and years of life lost (YLL) were estimated using the Global Burden of Disease methodology. National years lived with disability (YLDs) were calculated by applying a ratio between YLLs and YLDs found in a local injury data source, the Cape Metropole Study. Mortality and disability-adjusted life years’ (DALYs) rates were compared with African and global estimates. Findings Interpersonal violence dominated the South African injury profile with age-standardized mortality rates at seven times the global rate. Injuries were the second-leading cause of loss of healthy life, accounting for 14.3% of all DALYs in South Africa in 2000. Road traffic injuries (RTIs) are the leading cause of injury in most regions of the world but South Africa has exceedingly high numbers – double the global rate. Conclusion Injuries are an important public health issue in South Africa. Social and economic determinants of violence, many a legacy of apartheid policies, must be addressed to reduce inequalities in society and build community cohesion. Multisectoral interventions to reduce traffic injuries are also needed. We highlight this heavy burden to stress the need for effective prevention programmes.

Viabilidade da utilização do Google Earth na construção de mapas de setores urbanos para fins censitários.

A história dos Censos no Brasil mostra que a preocupação com a componente territorial em levantamentos estatísticos, surgiu no recenseamento de 1940, quando, pela primeira vez, o IBGE procurou retratar aspectos da realidade geográfica, de interesse para a operação de coleta, em bases cartográficas, uma tarefa complexa devido à grande extensão do território brasileiro e principalmente no que se refere à qualidade do material cartográfico disponível à época. Atualmente crescem as demandas em nosso país, por informações cada vez mais detalhadas e geograficamente posicionadas. Governadores e prefeitos, órgãos de planejamento municipais e estaduais, investidos de maior autonomia e de novas responsabilidades após a Constituição de 1988, dependem hoje como nunca dos censos para definirem suas políticas públicas, com base em informações atualizadas sobre a população sob suas jurisdições. Entretanto, as demandas por informações agregadas à posição também vêm de outras esferas, que vão do setor não-governamental e privado ao governo federal, fazendo com que muito aumentasse a relevância dos censos e por conseqüência os resultados das pesquisas. Para atender a grande demanda, o IBGE vem continuamente aperfeiçoando o que denominamos de Base Territorial, que é um sistema integrado de informações de natureza geográfica e alfanumérica e se constitui no principal requisito para a garantia da adequada cobertura das operações de levantamento censitário. Face a este novo cenário, o IBGE iniciou a elaboração de mapas da base territorial em meio digital, durante as ações preparatórias para o Censo 2000, se deparando com as dificuldades de integração das áreas urbanas e rurais e a baixa qualidade dos insumos de mapeamento em escala cadastral, disponível nas áreas menos desenvolvidas, pois a Instituição não é produtora de mapeamento em escala cadastral. A metodologia proposta visa melhorar a qualidade dos Mapas de Setores Urbanos MSU, com a utilização de imagens Google Earth, a partir software MicroStation 95, periféricos e aplicativos de conversão disponíveis no IBGE, com o estabelecimento de uma nova rotina de trabalho para produção e substituição dos mapas de setores urbanos, de forma a garantir uma maior representatividade territorial dos dados estatísticos para divulgação.

Distribution of Childhood Health Indices: Associations with Moves along the "Property Ladder"

Background
Childhood deprivation is a major risk to public health. Poor health in the early years accumulates and is expressed in adult health inequalities. The importance of social mobility - moves into and out of poverty or, indeed, change in relative affluence - for child wellbeing is less well understood. Home ownership and house value may serve as a useful measure of relative affluence and deprivation.
Method
Analysis of the Northern Ireland Longitudinal Study dataset focused on cohort members aged 18 and under at the 2001 census and their families. Using housing tenure and house value reported in 2001 and 2011, moves along the “housing ladder” over ten years were identified. Outcome measures were physical disability and mental health status as reported in 2011. Logistic regression models tested if health outcomes varied by upward and downward changes in house value.
Results
After controlling for variations in age, sex, general health and social class, mental health is worse among those who moved to a lower value house. Compared to ‘no change’, those moving from the upper quintile of house value into social renting accommodation were almost six times more likely to report poor mental health (OR 5.90 95% CI 4.52, 7.70). Conversely, those experiencing the greatest upward movement were half as likely to report poor mental health (OR 0.46 95% CI 0.31, 0.68). There were smaller associations between physical health and downward (OR 2.66 95% CI 2.16, 3.27), and upward (OR 0.75 95% CI 0.61, 0.92) moves.
Conclusion
Poor mental health is more strongly associated with declines in living standards than with improvements. The gradient appears at multiple points along this proxy affluence-deprivation spectrum, not only at the extremes. Further research should explore whether circumstances surrounding moves, or change in social position explains the differential association between the health correlates of upward versus downward mobility.

Usage de la force policière au Québec : une analyse des facteurs individuels, situationnels et contextuels

Au Québec, le policier a l’autorité de faire respecter plusieurs lois et d’assurer le maintien de l’ordre. Puisque le policier peut être confronté à une multiplicité de problématiques, il est, dans certaines circonstances, contraint à employer une force pour se protéger lui-même ou pour protéger toute autre personne contre la mort ou contre des lésions corporelles graves. Cependant, bien que l’usage de la force par la police soit l’un des éléments les plus visibles et les plus controversés de l’intervention policière, les connaissances sur ce sujet spécifique demeurent limitées. Afin de pallier à certaines lacunes de la recherche et de la théorie, l’objectif général de ce mémoire vise à identifier les facteurs individuels, situationnels et contextuels liés au niveau de force utilisé par la police lors d’une intervention dans les postes de quartier et dans les secteurs de recensement. Les données dans le cadre de cette étude proviennent des rapports d’incidents déclarés d’usage de la force d’un service de police canadien pour une période couvrant les années 2007 à 2011, les données issues du recensement canadien de 2006 et les données criminelles issues du Programme de déclaration uniforme de la criminalité (DUC). La stratégie analytique privilégiée est la modélisation hiérarchique qui permettra de tester les liens entre les différents niveaux d’analyse. Au terme des analyses multiniveaux, les résultats indiquent que plusieurs facteurs ont un impact sur le niveau de force utilisé par le policier. Au niveau des déterminants individuels du sujet, c’est le fait d’être un homme, de résister physiquement à l’intervention et de posséder une arme qui est associé à des niveaux plus élevés de force. Au niveau des facteurs contextuels, on découvre que la proportion de minorité visible et le désavantage social ont un impact appréciable sur le niveau de force utilisé par le policier. Ces résultats nous amènent donc à conclure que les policiers tiennent surtout compte de la situation immédiate (facteurs individuels et situationnels) pour évaluer le degré de dangerosité ou de menace, mais qu’ils sont également influencés par l’endroit où ils se trouvent. D’autres études sont toutefois nécessaires pour vérifier la constance de nos résultats.

Analyse des facteurs biodémographiques, sociéconomiques et familiaux de la longévité exceptionnelle

La recherche des facteurs de longévité gagne en intérêt dans le contexte actuel du vieillissement de la population. De la littérature portant sur la longévité et la mortalité aux grands âges, un constat émerge : bien que les déterminants associés à la survie humaine soient multiples, l'environnement familial aurait un rôle déterminant sur la mortalité et sur l'atteinte des âges avancés. Dès lors, l'objectif de cette thèse est d'évaluer les déterminants de la survie exceptionnelle et d'examiner le rôle des aspects familiaux, en début de vie et à l'âge adulte, dans les différentiels de durée de vie. Plus spécifiquement, elle vise à : (1) examiner la similarité des âges au décès entre frères, soeurs et conjoints afin d'apprécier l'ampleur de la composante familiale de la longévité; (2) explorer, d'un point de vue intrafamilial, les conséquences à long terme sur la survie des variables non partagées issues de la petite enfance tels l'âge maternel à la reproduction, le rang de naissance et la saison de naissance; et (3) s'interroger sur le rôle protecteur ou délétère de l’environnement et du milieu familial d'origine dans l’enfance sur l'atteinte des grands âges et dans quelle mesure le statut socioéconomique parvient à médiatiser la relation. Cette analyse s'appuie sur le jumelage des recensements canadiens et des actes de décès de l’état civil québécois et emploie des données québécoises du 20e siècle issues de deux échantillons distincts : un échantillon aléatoire représentatif de la population provenant du recensement canadien de 1901 ainsi qu’un échantillon de frères et soeurs de centenaires québécois appartenant à la même cohorte. Les résultats, présentés sous forme d'articles scientifiques, ont montré, en outre, que les frères et soeurs de centenaires vivent plus longtemps que les individus appartenant aux mêmes cohortes de naissance, reflétant la contribution d'une robustesse commune, mais également celle de l'environnement partagé durant la petite enfance. Ces analyses ont également témoigné d'un avantage de survie des conjoints des centenaires, soulignant l'importance d'un même environnement à l'âge adulte (1er article). De plus, nos travaux ont mis de l'avant la contribution aux inégalités de longévité des variables biodémographiques issues de l'environnement non partagé telles que l'âge maternel à la reproduction, le rang de naissance et la saison de naissance, qui agissent et interagissent entre elles pour créer des vulnérabilités et influer sur l'atteinte des âges exceptionnels (2e article). Enfin, une approche longitudinale a permis de souligner la contribution du milieu social d'origine sur la longévité, alors que les individus issus d’un milieu socioéconomique défavorisé pour l'époque (milieu urbain, père ouvrier) vivent moins longtemps que ceux ayant vécu dans un environnement socioéconomique favorable (milieu rural, fermier), résultat d'une potentielle accumulation des avantages liée à la reproduction du statut social ou d'une programmation précoce des trajectoires de santé. L’influence est toutefois moindre pour les femmes et pour les frères de centenaires et s'exprime, dans ce cas, en partie par l'effet de la profession à l'âge adulte (3e article).

Understanding cange in residential property markets: Mapping residency of employment data

The changing nature of residential housing markets is due to a large number of influences, although some have a larger effect than others do on house values. Whilst it is extremely difficult to completely disaggregate all influencing factors, it is possible to highlight areas that have a strong relationship with property – one of these is residency of employment. This research investigates these links between residential housing markets as measured by the level of house prices and residency of employment as measured by industry sector employment. It focuses on Local Government Areas in the State of Victoria, Australia and examines change over a ten year period between 1991 and 2001 using census and house price information. It is supported by data sourced from the Australian Bureau of Statistics and the Victorian Government’s Valuer General’s Office. The analysis also considers changes in these employment sectors from Australia’s overall perspective, as well as comparison with changes in Victoria’s overall residency of employment trends. It is assisted by a spatial representation of three 'shift-share' components and property values with the support of a geographical information system (GIS).

Investigating residential property markets using employment data

The changing nature of residential housing markets is due to a large number of influences, although some factors have a larger effect than others on house values. Whilst it is extremely difficult to completely disaggregate all influencing factors, it is possible to highlight areas that have a strong relationship with property – one of these is employment. Due to the growing importance between housing affordability and the capacity to meet the cost of living the form of regular mortgage repayments or rent, there are clear links between the cost of housing and the ability to pay for the housing product.

Socio-economic inequalities in mortality persist into old age in New Zealand : study of all 65 years plus, 2001-04

A number of studies have explored the relationship between socioeconomic status (SES) and mortality, although these have mostly been based on the working age population, despite the fact that the burden of mortality is highest in older people. Using Poisson regression on linked New Zealand census and mortality data (2001 to 2004, 1.3 million person years) with a comprehensive set of socioeconomic indicators (education, income, car access, housing tenure, neighourhood deprivation) we examined the association of socioeconomic characteristics and older adult mortality (65+ years) in New Zealand. We found that socioeconomic mortality gradients persist into old age. Substantial relative risks of mortality were observed for all socioeconomic factors, except housing tenure. Most relative risk associations decreased in strength with aging (e.g. most deprived compared to least deprived rate ratio for males reducing from 1.40 (95% CI 1.28 to 1.53) for 65-74 year olds to 1.13 (1.00 to 1.28) for 85+ year olds), except for income and education among women where the rate ratios changed little with increasing age. This suggests individual level measures of SES are more closely related to mortality in older women than older men. Comparing across genders, the only statistically significantly different association between men and women was for a weaker association for women for car access.
