Reformulating the rj-McMC Algorithm for 3D Inversion of Passive Seismic Data for Near-Surface Characterization
No full textGeophysical subsurface characterization techniques could, due to their non-invasive nature, play a crucial role in the design and subsequent construction of infrastructure in urban & industrial environ- ments. Geo-data specialist company Fugro sees potential in upgrading their current ambient-seismic- noise-tomography workflow, to make use of state-of-the-art inversion schemes with the main goal of increasing the quality and accuracy of the initial-site characterization delivered to clients. In this thesis I explore the feasibility of utilizing the reverse-jump Markov chain Monte Carlo (rj-McMC) algorithm for the inversion of ambient seismic noise for characterization in urban & industrial environments. Specif- ically, testing the potential of scaling down this inversion algorithm to fit in a small scale, near-surface framework. To achieve this, I first carried out analyses to evaluate the appropriate Rayleigh wave frequency range, after which realistic noise hyperparameters, suited for this reduced scale problem, were obtained. Because of the potential exploitation of in-situ borehole measurements, I reformulated the Bayesian prior within the rj-McMC algorithm to implement these constraining shear wave velocity values appropriately. I conducted extensive synthetic experiments to gain insight into the behavior of this adapted algorithm, from which it was concluded that the inherent dynamic discretization partially prevents these constraints from being implemented to their full extent. Nevertheless, promising results lead me to conclude that the use of the rj-McMC algorithm for application in near-surface urban & industrial environments is feasible.Applied Geophysics | IDEA Leagu

proposta por Sullivan e estimar a expectativa de vida
saudável, utilizando diferentes formas de mensurar o
estado de saúde, com base em informações provenientes
da Pesquisa Mundial de Saúde realizada no Brasil
em 2003. Pela combinação de informação de mortalidade
e morbidade num único indicador, simplicidade
do cálculo e fácil interpretação dos resultados, o
método de Sullivan é atualmente o mais usado para
estimar expectativa de vida saudável. Os resultados
mostraram que a maior perda de anos saudáveis é obtida
quando há ocorrência de doença de longa duração
ou incapacidade que limitam as atividades habituais,
independentemente do grau de dificuldade em
realizar as atividades cotidianas e a severidade das limitações
funcionais. As duas estimativas de expectativa
de vida saudável ajustadas pela severidade das limitações
mostraram resultados muito similares àquelas
estimadas com base na percepção do estado de
saúde, especialmente para as idades avançadas. Observa-
se, para todas as medidas utilizadas, que a proporção
de anos perdidos de vida saudável aumenta
significativamente com a idade e que, embora as mulheres
tenham uma expectativa de vida maior que a
dos homens, elas vivem proporcionalmente menos
anos com boa saúde.The objective of this study is to present the method proposed by Sullivan and to estimate the healthy life expectancy using different measures of state of health, based on information from the World Health Survey carried out in Brazil in 2003. By combining information on mortality and morbidity into a unique indicator, simple to calculate and easy to interpret, the Sullivan method is currently the one most commonly used for estimating healthy life expectancy. The results show higher number of healthy years lost if there is a long-term disease or disability that limits daily activities, regardless of the difficulty in performing such activities or the severity of the functional limitations. The two measures of healthy life expectancy adjusted by the severity of functional limitation show results very similar to estimates based on the perception of state of health, especially in advanced age. It was also observed, for all measures used, that the proportion of healthy years lost increases significantly with age and that, although females have higher life expectancy than males, they live proportionally less years in good health

Educator Perceptions of Restorative Justice Practices That Provide Academic Support for Students With Adverse Childhood Experiences
No full textThe phenomenon of adverse childhood experiences (ACE) has been of interest to scholars since the late 1990s when their impact on life outcomes concerning physical and mental health was first acknowledged. Educators are challenged to support students who have experienced ACE, but many have implemented alternative practices such as restorative justice (RJ) to support students’ academic needs. There is insufficient empirical evidence to determine how elements of RJ support high school students who have experienced ACE. The purpose of this qualitative case study was to investigate the RJ practices that teachers, administrators, and other school personnel have implemented to support the academic needs of students with ACE. Vygotsky’s theory of social constructivism was used to inform how RJ can support students with ACE and to examine the practices that are most helpful. Data were collected using semistructured interviews with six teachers and administrators who worked closely with students with ACE in an RJ educational setting. Results indicated that building positive relationships is the foundation of restorative justice in schools; once students feel safe and respected and have positive relationships within the school, student outcomes improve. Students and educators may benefit as a result of the current study, which could contribute empirical evidence of RJ practices that could provide academic support to students with ACE. This evidence would have the potential to influence positive social change by informing educational strategies, professional development for educators, and educator training programs
Radiation-induced root surface caries restored with glass-ionomer cement placed in conventional and ART cavity preparations: Results at two years
No full textThe document attached has been archived with permission from the Australian Dental Association (8th Jan 2008). An external link to the publisher’s copy is included.Background: There are no published studies comparing the clinical performances of more-viscous glass-ionomer cement (GIC) restorations when placed using conventional and atraumatic restorative treatment (ART) cavity preparation methods to restore root surface caries. Methods: One dentist used encapsulated Fuji IX GP and Ketac-Molar to restore 72 conventional and 74 ART cavity preparations for 15 patients who had received cervicofacial radiation therapy. Two assessors evaluated the restorations at six, 12, and 24 months for retention, marginal defects and surface wear, and recurrent caries. Results: After two years, the cumulative restoration successes were 65.2 per cent for the conventional and 66.2 per cent for the ART cavity preparations, without statistical or clinical significance (P>0.50). Restoration dislodgement accounted for 82.8 per cent and marginal defects for 17.2 per cent of all failures. There were no instances of unsatisfactory restoration wear or recurrent caries observed. Teeth with three or more restored cervical surfaces accounted for 79.3 per cent of all failures (P<0.0001). Conclusions: For root surface caries restored with GIC, the use of hand instruments only with the ART method was an equally effective alternative to conventional rotary instrumentation for cavity preparation. Larger restorations had higher failures, usually from dislodgement.JY Hu, XC Chen, YQ Li, RJ Smales and KH Yi

The longitudinal association between external locus of control, social cognition and adolescent psychopathology
No full textPurpose
To investigate the longitudinal associations between social cognitive ability an external locus of control (externality) and adolescent psychopathology.
Methods
7058 participants from a prospective population-based cohort provided data on externality, social communication and emotion perception between 7 to 16 years and psychotic experiences and depressive symptoms at 12 and 18 years. Bivariate probit modelling was used to investigate associations between these risk factors and psychopathological outcomes.
Results
Externality was associated with psychopathology at 12 (psychotic experiences OR1.23 95%CI 1.14,1.33; depression OR1.12 95%CI 1.02,1.22) and 18 years (psychotic experiences OR1.38 95% CI1.23,1.55; depression OR1.40 95% CI1.28,1.52). Poor social communication was associated with depression at both ages (12 years OR1.22 95%CI 1.11,1.34; 18 years OR1.21 95%CI 1.10,1.33) and marginally associated with psychotic experiences. There was marginal evidence of a larger association between externality and psychotic experiences at 12 years (p=0.06) and between social communication and depression at 12 years (p=0.03).
Conclusions
Externality was more strongly associated with psychotic experiences. At 18 years change in externality between 8 and 16 years was associated with a larger increase in the risk of depression. Poor social communication was more strongly associated with depression
