Study of the spatial variation of the biodegradation rate of the herbicide bentazone with soil depth using contrasting incubation methods

Vertical and horizontal spatial variability in the biodegradation of the herbicide bentazone was compared in sandy-loam soil from an agricultural field using sieved soil and intact soil cores. An initial experiment compared degradation at five depths between 0 and 80 cm using sieved soil. Degradation was shown to follow the first-order kinetics, and time to 50% degradation (DT50), declined progressively with soil depth from 56 d at 0–10 cm to 520 d at 70–80 cm. DT50 was significantly correlated with organic matter, pH and dehydrogenase activity. In a subsequent experiment, degradation rate was compared after 127 d in sieved soil and intact cores from 0 to 10 and 50 to 60 cm depth from 10 locations across a 160 × 90 m portion of the field. Method of incubation significantly affected mean dissipation rate, although there were relatively small differences in the amount of pesticide remaining in intact cores and sieved soil, accounting for between 4.6% and 10.6% of that added. Spatial variability in degradation rate was higher in soil from 0 to 10 cm depth relative to that from 50 and 60 cm depth in both sieved soil and intact core assessments. Patterns of spatial variability measured using cores and sieved soil were similar at 50–60 cm, but not at 0–10 cm depth. This could reflect loss of environmental context following processing of sieved soil. In particular, moisture content, which was controlled in sieved soil, was found to be variable in cores, and was significantly correlated with degradation rate in intact topsoil cores from 0 to 10 cm depth

The Relationship Between Social Innovation and Active Mobility Public Services

This article aims to discuss the relationship between social innovation and public services on active mobility. Two active mobility initiatives are considered in the city of São Paulo, and analyzed based on 11 variables that characterize social innovation. Through the mapping of recent Brazilian regulatory frameworks for active mobility and a low-carbon economy, we can propose the following relationship: the more local (municipal) the public policy, the greater its social influence and participation. However, despite the advances indicated by both experiences of active mobility analyzed (highlighting the role of organized civil society), and by the progress in the regulatory framework, until now innovative practices in the local context have been restricted to the treatment of pedestrian spaces. Therefore, there exists a great potential for the continued introduction of innovations in the improvement and scale of public services for pedestrian mobility, following the paradigm of sustainable urban mobility, and based on social participation

Is stock market volatility persistent? A fractionally integrated approach

This paper seeks to study the persistence in the G7’s stock market volatility, which is carried out using the GARCH, IGARCH and FIGARCH models. The data set consists of the daily returns of the S&P/TSX 60, CAC 40, DAX 30, MIB 30, NIKKEI 225, FTSE 100 and S&P 500 indexes over the period 1999-2009. The results evidences long memory in volatility, which is more pronounced in Germany, Italy and France. On the other hand, Japan appears as the country where this phenomenon is less obvious; nevertheless, the persistence prevails but with minor intensity

Rede Social Pessoal de Cuidadores Informais de Adultos com Necessidades Especiais

Objetivo. Devido ao aumento da esperança de vida, os adultos com necessidades especiais vivem mais tempo, sendo os seus principais cuidadores, geralmente familiares, também mais envelhecidos. Tal situação representa novas necessidades específicas de apoio, sendo inúmeros os desafios colocados ao Serviço Social no sentido de garantir o bem-estar da pessoa com incapacidade e dos seus cuidadores. Assim, este estudo tem como objetivo realizar um levantamento das necessidades de apoio e a caraterização da rede social pessoal de apoio do cuidador informal de adultos com necessidades especiais. Participantes. A amostra é constituída por 40 cuidadores informais de adultos com necessidades especiais, integrados na resposta social “Centro de Atividades Ocupacionais-CAO” da Associação de Paralisia Cerebral de Coimbra, de ambos os sexos com idade igual ou superior a 40 anos. Material e métodos. Foi utilizado o Instrumento de Avaliação da Rede Social Pessoal e um questionário para caracterização sociodemográfica e sociofamiliar dos cuidadores, assim como para avaliação de necessidades. Resultados. Aproximadamente um terço dos cuidadores relatou a experiência de níveis moderados de sobrecarga associada à prestação de cuidados, enquanto mais de metade relatou a experiência de níveis elevados e muito elevados dessa sobrecarga; o apoio financeiro foi referido como a forma de apoio mais necessária no presente, ainda que o apoio em residência tenha sido percecionado por cerca de um terço dos cuidadores como a forma de apoio mais necessária no futuro; enquanto mais de metade considerou o apoio domiciliário e de unidade residencial (institucional). Estes cuidadores familiares referiram a "incerteza" e a "esperança" como os sentimentos mais frequentemente experienciados em relação ao futuro das suas vidas. No que respeita às redes sociais, as relações familiares são centrais a nível estrutural; em termos de caraterísticas funcionais da rede, foram observados valores mais elevados para as dimensões de reciprocidade do apoio e satisfação com a rede social. Implicações. Este estudo sublinha a importância da avaliação das necessidades de apoio dos cuidadores familiares de adultos com necessidades especiais. A sua implementação sistemática pode auxiliar a tomada de decisão baseada na evidência empírica para as intervenções do Serviço Social, tais como na planificação e gestão de respostas e serviços sociais, a par do reconhecimento e ativação dos recursos das próprias famílias, de forma a promover a eficiência dos recursos e eficácia das intervenções, focadas no bem-estar do cidadão com deficiência e das suas famílias. / Aim. The general increase in human life expectancy has resulted in greater rates of survival for adults with special care needs, as well as for their ageing family caregivers. This situation poses different and specific support needs, which represent a major challenge in social work interventions aimed at ensuring the well-being of disabled persons and their caregivers. Therefore, this study was aimed to describe the needs for support and the perceived social support network of family caregivers of adults with special care needs. Participants. The sample for this study comprised 40 family caregivers of disabled adults with special care needs, of both genders and aged 40 years old at minimum, who attended a long-term care facility at Coimbra Cerebral Palsy Association. Material and methods. Participants were administered a self-report questionnaire on socio-economic, family and caregiving needs, along with the Instrument for Assessing Personal Social Networks. Results. Nearly one third a family caregivers experienced moderate caregiving burden, while more than half experienced high or very high levels of caregiving burden; financial support was perceived as the most needed form of support in the present, but residential home care was identified as the most needed form of support in the future; while more than a half considered home-based support and residential support viable options for their disabled family members with special care needs. These family caregivers reported "uncertainty" and "hope" as the most common feelings towards their family life in the future. On the topic of social networks, family relations were found to be crucial at the structural level; in terms of functional characteristics of the network, elevated scores were observed for reciprocity of support and satisfaction with the social network. Implications. This study highlights the importance of increasing the specificity of the assessments of needs for support in family caregivers of disabled adults with special care needs. The systematic conduction of these assessments may assist evidence-based decision making in social work interventions, such as for planning and managing social services, acknowledging and activating the families' own resources, and ultimately promote the efficacy and effectiveness 57 interventions aimed at improving the well-being of disabled citizens and their families
