Acquisition and loss of Porphyromonas gingivalis, Actinobacillus actinomycetemcomitans and Prevotella intermedia over a 5-year period: effect of a triclosan/copolymer dentifrice

Objectives: The present study describes the natural history of Porphyromonas gingivalis, Actinobacillus actinomycetemcomitans and Prevotella intermedia over a 5-year period and the effect of a triclosan/copolymer dentifrice on these organisms in a normal adult population. Material and Methods: Subgingival plaque samples were collected from 504 adult volunteers. Probing pocket depths (PPD) and relative attachment levels were measured using an automated probe. Participants were matched for disease status (CPI), plaque index, age and gender, and allocated to receive either a triclosan/copolymer or placebo dentifrice. Re-examination and subgingival plaque sampling was repeated after 1, 2, 3, 4 and 5 years. P. gingivalis, A. actinomycetemcomitans and P. intermedia were detected and quantitated using an enzyme linked immunosorbent assay. Logistic regression and generalised linear modelling were used to analyse the data. Results: This 5-year longitudinal study showed considerable volatility in acquisition and loss (below the level of detection) of all three organisms in this population. Relatively few subjects had these organisms on multiple occasions. While P. gingivalis was related to loss of attachment and to PPD greater than or equal to3.5 mm, there was no relationship between A. actinomycetemcomitans or P. intermedia and disease progression over the 5 years of the study. Smokers with P. gingivalis had more PPD greater than or equal to3.5 mm than smokers without this organism. There was no significant effect of the triclosan dentifrice on P. gingivalis or A. actinomycetemcomitans . Subjects using triclosan were more likely to have P. intermedia than those not using the dentifrice; however this did not translate into these subjects having higher levels of P. intermedia and its presence was uniform showing no signs of increasing over the course of the study. Conclusion: The present 5-year longitudinal study has shown the transient nature of colonisation with P. gingivalis , A. actinomycetemcomitans and P. intermedia in a normal adult population. The use of a triclosan-containing dentifrice did not lead to an overgrowth of these organisms. The clinical effect of the dentifrice would appear to be independent of its antimicrobial properties.

On the robustness of short-term interest rate models

This paper investigates the robustness of a range of short–term interest rate models. We examine the robustness of these models over different data sets, time periods, sampling frequencies, and estimation techniques. We examine a range of popular one–factor models that allow the conditional mean (drift) and conditional variance (diffusion) to be functions of the current short rate. We find that parameter estimates are highly sensitive to all of these factors in the eight countries that we examine. Since parameter estimates are not robust, these models should be used with caution in practice.

Aligning school reform and teacher education reform in the middle years: An Australian case study

This paper discusses the development of a new Bachelor of Education (Middle Years of Schooling) at The University of Queensland. The middle years of schooling have increasingly been the focus of education reform initiatives in Australia, but this has not been accompanied by significant increases in the number of teacher education institutions offering specialised middle schooling-level teacher preparation programmes. Considering the rapidly changing social and economic context and the emergent state of middle schooling in Australia, the programme represented a conceptual and practical opportunity and challenge for The University of Queensland team. Working collaboratively, the team sought to design a teacher education preservice programme that was both responsive and generative: that is, responsive to local school contexts and to current educational research and reform at national and international levels; and generative of cutting-edge theories and practices associated with middle schooling, teachers' work, and teacher education. This paper focuses on one component of the Middle Years of Schooling Teacher Education programme at The University of Queensland; namely, the practicum. We first present the underlying principles of the practicum programme and then examine "dilemmas" that emerged early in the practicum. These issues and tensions were associated with the ideals of "middle years" philosophy and the pragmatics of school reform associated with that new approach. In this paper, and within this context, we explore what it means to be both responsive and generative, and describe how we as teacher educators negotiated between the extremes these terms implied.

Influência da luminosidade na fisiologia e morfoanatomia de jequitibá branco (Cariniana estrellensis (Raddi.) Kuntze) e jequitibá rosa (Cariniana legalis (Mart.) Kuntze)

Cariniana estrellensis (Raddi.) Kuntze e C. legalis (Mart.) Kuntze são arbóreas nativas do Brasil que, além de possuírem alto poder econômico, são objeto de interesse em programas de recuperação de áreas degradadas e em plantios comerciais. A escassez de informações relacionadas ao desempenho ecofisiológico dessas espécies em condições ambientais estressantes dificultam o manejo e conservação das mesmas. Dessa forma, o presente estudo objetivou avaliar a ecofisiologia das espécies em um gradiente de irradiância, por meio de dois experimentos. No experimento 1, plantas de C. estrellensis com 12 meses de idade foram submetidas a quatro tratamentos: 40%, 50%, 70% e 100% de irradiância, durante 104 dias. Ao final desse período foram feitas análises de crescimento, do conteúdo de pigmentos fotossintéticos, de trocas gasosas, da fluorescência da clorofila a, do conteúdo foliar de carboidratos solúveis, das características anatômicas foliares e caulinares e da plasticidade fenotípica da espécie. No experimento 2, plantas de C. estrellensis e C. legalis com 14 meses de idade foram submetidas a dois tratamentos: 30% e 100% de irradiância (sombra e sol, respectivamente), durante 30 dias. Ao final desse período foram feitas análises do estresse oxidativo das espécies, por meio da quantificação da atividade das enzimas catalase e peroxidase do ascorbato e por meio da quantificação do conteúdo foliar de pigmentos fotossintéticos. No experimento 1, em 70% de irradiância, as plantas apresentaram melhor crescimento em altura e diâmetro, maior massa seca de folhas (MSF), de caule (MSC) e de raiz (MSR). Em 70% e 100% de irradiância, as plantas apresentaram folhas menores (AFU) e mais espessas (AFE e MFE) resultando em menor área foliar total (AFT). Nesses tratamentos as plantas também apresentaram menor conteúdo foliar de clorofila a (Chl a) e b (Chl b), porém, maior razão Chl a/b e maior conteúdo de carotenóides, o que implicou em menor razão Chl a/Carot. Taxas fotossintéticas maiores foram encontradas nas plantas em 70% e inibidas em 40% e 50%, em função da baixa irradiância solar, e em 100%, possivelmente pela ocorrência de fotoinibição, como mostraram os parâmetros do fluxo de energia do fotossistema II. De acordo com a análise da fluorescência da clorofila a, em pleno sol, as plantas apresentaram menor densidade de centros de reação ativos (RC/ABS) e maior dissipação de energia (DI0/ABS), culminando com menor desempenho do fotossistema II (PIabs) e desempenho total (PITotal). O conteúdo foliar de carboidratos solúveis foi maior nas plantas em 70%, seguido das plantas em 100% de irradiância, com exceção da glicose, que não variou entre os tratamentos. A maior espessura encontrada nas folhas sob 100% de irradiância foi em função da maior espessura das epidermes adaxial e abaxial e dos parênquimas paliçádico e esponjoso. E o maior diâmetro do caule em 70% de irradiância se deu pela maior espessura do xilema e floema secundários. No experimento 2, as plantas em pleno sol de ambas as espécies também apresentaram menor conteúdo foliar de clorofila a (Chl a) e b (Chl b) e maior razão Chl a/b. No entanto, o conteúdo de carotenóides foi maior, o que implicou em menores razões Chl a/Carot. A atividade da catalase (CAT) variou em função do tempo e da espécie, apresentando uma queda em C. estrellensis aos 16 dias, possivelmente em função de fotoinativação, e um aumento em C. legalis aos 30 dias. Já a atividade da peroxidase do ascorbato (APX) não variou em função do tempo, da espécie ou dos tratamentos. O estudo da plasticidade fenotípica mostrou que C. estrellensis é uma espécie plástica, principalmente em função das variáveis de fotossíntese e trocas gasosas, sendo capaz de sobreviver no gradiente de irradiância testado, o que viabiliza o seu uso em projetos de recuperação de áreas degradadas. E, uma vez que as análises ecofisiológicas mostraram que C. estrellensis e C. legalis apresentaram melhor desempenho em luminosidade moderada, sugere-se que ambas comportaram-se como espécies intermediárias no processo de sucessão florestal. No entanto, uma vez que a concentração de pigmentos foliares e a produção de enzimas antioxidantes inferiram maior susceptibilidade de C. estrellensis à fotoinibição em alta irradiância, sugere-se maior viabilidade do uso de C. legalis em projetos de recuperação de áreas degradas.

Os fundos de investimento imobiliário listados em bolsa e as variáveis que influenciam seus retornos

Os fundos de investimento imobiliário combinam características tanto do mercado imobiliário, fonte de seus rendimentos, quanto do mercado de capitais, ambiente em que são negociados. O impacto de cada um desses mercados subjacentes no comportamento, desempenho e risco dessa classe de ativos não é, no entanto, ainda claramente definida, sendo um dos grandes temas em análise, tanto na literatura acadêmica, quanto na indústria de fundos internacionais. Em face da significativa expansão dessa alternativa de investimento no mercado brasileiro, no presente estudo foram analisadas as variáveis que influenciam os retornos dos fundos imobiliários brasileiros para uma amostra de fundos listados em Bolsa de Valores de São Paulo, período de 2008-2013. Seguindo a metodologia de Clayton e Mackinnon (2003), os fatores explicativos dos retornos foram decompostos em quatro componentes principais, sendo três fatores de retorno de mercado (mercado de ações, mercado de renda fixa e mercado imobiliário) e risco idiossincrático. De acordo com a estatística descritiva, os fundos imobiliários da amostra apresentaram maior retorno em relação aos demais mercados, exceto em comparação com o mercado imobiliário, porém com menor risco. As análises de correlação, regressão e decomposição da variância indicam que o mercado de ações e o mercado imobiliário direto são, em geral, significativos no modelo, porém explicam apenas cerca de 15% da volatilidade dos retornos dos fundos da amostra. À luz da Moderna Teoria do Portfólio, esses resultados indicam que a inclusão de fundos imobiliários pode ter potencial diversificador numa carteira multi-ativo, seja aumentando o retorno total de uma carteira formada de ações e títulos de renda fixa, sem acréscimo em risco; ou mantendo o retorno dessa carteira, com diminuição da volatilidade, ampliando assim a fronteira eficiente da carteira. Esse efeito questiona o tradicional equilibrium fund de carteiras de investimentos formadas apenas de ações e renda fixa e aponta os fundos imobiliários como uma alternativa de investimento diversificadora, enquanto classe de ativo única. A análise de subamostras por tipologia indica, porém, que o papel diversificador dos fundos imobiliários está atrelado ao tipo de empreendimento que lastreia esse fundo, uma vez que os fatores explicativos e seus impactos nos retornos diferem de uma tipologia para outra. Esse resultado tem importantes implicações no critério de seleção a ser adotado tanto por investidores para seleção de ativos para uma carteira otimizada, como para gestores de fundos imobiliários na formatação e gestão desses produtos. Conclui-se também que os retornos dos fundos, de certo modo, refletem seu caráter híbrido, mas o modelo decomposto em 4 componentes não é suficiente para explicar os retornos dos fundos imobiliários, uma vez que o modelo estendido, demonstrou que outras variáveis, inclusive parâmetros desses próprios mercados, além de variáveis macroeconômicas e as características de cada fundo (eg. market-to-book, tamanho), podem ser responsáveis por explicar considerável parte da variância dos retornos dos FIIs.

Swords into ploughshares? China's Soft Power strategy in Southeast Asia and its challenges1

Since the 1990s, alongside China's economic growth, the international community has fostered a general anxiety towards a "China threat." In order to relieve itself from suspicion, China adopted the dual strategies of "harmonious worldview" and "good neighbor policy." The strategies led to the use of soft power in China's foreign policy. China aimed to reduce security concerns implied by the threat theory by supporting an image that caters to international peace and development. This article seeks to explain how China achieves its interests in Southeast Asia through the use of soft power. The authors address the concepts of "harmonious worldview" and "good neighbor policy" and how the twin strategies and soft power have shaped China's foreign policy in recent years. This article aims to provide insights into China's policy options in Southeast Asia in the near future.

Loneliness in Middle and Old Age

Purpose of the research: (a) To identify the degree of much loneliness reported in the Portuguese population over 50 years of age and (b) test whether loneliness can be predicted by socio-demographic, health related or social characteristic of the sample other than age. Materials and methods: 1174 late middle age and older adults were interviewed face to face by different interviewers across the country; after the informed consent was signed, we asked the participants several socio-demographic and health-related questions; finally we asked ‘‘How often do you feel lonely?’’ and participants responded according to a five point Likert scale. Principal results: The results showed that 12% of participants reporting feeling lonely often or always, whereas 40% reporting never feeling lonely. The remaining 48% self-reported they felt lonely seldom or sometimes. Additionally, results show that, when taken together, variables such as marital status, type of housing, residence settings, health conditions, social satisfaction, social isolation, lack of interest, transportation, and age were predictors of loneliness. Major conclusions: (1) The association of loneliness with advanced age has been greatly exaggerated by mass media and common sense; (2) But although our findings did not confirm the most alarmist views, the 12% of older adults reporting that they are feeling lonely always or often should be cause for attention and concern. It is necessary to understand the meaning, reasons and level of suffering implied on those feelings of loneliness. (3) Our findings suggest that it makes no sense to construe age as a singular feature or cause for feelings of loneliness. Instead, age and also a number of other features combine to predict feelings of loneliness. But even with our predictor variables there was a substantial of variance left unexplained. Therefore it is necessary to continue exploring how feelings of loneliness arise from the experience of living and how they can be changed.

Finantial risk analysis of portuguese textile and tourism companies

Textile and tourism sectors are two important industries in the Portuguese economy. However, its high exposure to both internal and international economic volatility make the companies operating in these economic sectors particularly vulnerable to economic crises, such as the ones which have been impacting Portugal and the European Union. The objective of this paper is to evaluate and understand the impact of size and age on the financial health of textile and tourism companies, measured by economic indices. An empirical based model is proposed. Its implications are derived and tested on a sample of 4061 Portuguese companies from textile and tourism sectors, during the period 2005-2009. The findings suggest that age has a major impact on the risk of failure, rather than size. Whereas the effect of age is generally positive regarding the financial health of the company, the effect of size is less clear and ultimately depends on the age of the company.
