Range Unit Root (RUR) Tests: Robust against Nonlinearities, Error Distributions, Structural Breaks and Outliers
No full textSince the seminal paper by Dickey and Fuller in 1979, unit-root tests have conditioned the standard approaches to analysing time series with strong serial dependence in mean behaviour, the focus being placed on the detection of eventual unit roots in an autoregressive model fitted to the series. In this paper, we propose a completely different method to test for the type of long-wave patterns observed not only in unit-root time series but also in series following more complex data-generating mechanisms. To this end, our testing device analyses the unit-root persistence exhibited by the data while imposing very few constraints on the generating mechanism. We call our device the range unit-root (RUR) test since it is constructed from the running ranges of the series from which we derive its limit distribution. These nonparametric statistics endow the test with a number of desirable properties, the invariance to monotonic transformations of the series and the robustness to the presence of important parameter shifts. Moreover, the RUR test outperforms the power of standard unit-root tests on near-unit-root stationary time series; it is invariant with respect to the innovations distribution and asymptotically immune to noise. An extension of the RUR test, called the forward?backward range unit-root (FB-RUR) improves the check in the presence of additive outliers. Finally, we illustrate the performances of both range tests and their discrepancies with the Dickey?Fuller unit-root test on exchange rate series.Publicad
The Role of Coping Humour in the Physical and Mental Health of Older Adults
No full textObjectives - This study examined the associations among coping humor, other personal/social factors, and the health status of community-dwelling older adults. Method - Survey questionnaires were completed with 73 community dwelling older adults. Included were measures of coping humor, spirituality, self-efficacy, social support and physical and mental health status. Results - Correlations across all variables showed coping humor to be significantly associated with social support, self-efficacy, depression, and anxiety. Forward stepwise regression analyses showed that coping humor and self-efficacy contributed to outcome variance in measures of mental health status. Contrary to expectation, neither social support nor spirituality contributed to the total outcome variance on any of the dependant measures. Conclusion - The importance of spirituality, self-efficacy and social support in determining the quality of life of older adults is well supported in the literature. Coping humor as a mechanism for managing the inevitable health stresses of aging has received less attention. This study shows that coping humor and self efficacy are important factors for explaining health status in older adults. Correlations among coping humor, self efficacy, and social support suggest that a sense of humor may play an important role in reinforcing self-efficacious approaches to the management of health issues.coping humor, aging, health status
Assessing Alternative Financing Methods for the Canadian Health Care System in View of Population Aging
No full textThe cost of the Canadian health care system is approximately 10% of Gross Domestic Product (GDP). Survey-evidence suggests that Canadians do not wish to have additional funds spent on health care but believe that the system should be able to deliver better quality care. Due to low fertility rates and increasing life expectancy, the Canadian population is aging. Over the next 25 years, the dependency ratio will increase, primarily due to the aging of the “baby boom generation” 2. This will place twofold cost pressures on governments responsible for maintaining the health care system: 1) As a consequence of increased life expectancy, on average, Canadians will have a longer period of health care consumption. Although age-specific cost may not increase, with an aging population aggregate annual health care expenditures are expected to increase. 2) The dependency ratio is a proxy for the ability of the population to support itself. The increasing dependency rate may result in a slowdown in GDP growth, given constant technology. In Section I, this paper attempts to quantify these factors. A single measure combining cost and quality is developed to demonstrate the magnitude of the challenge. In Section II, this paper examines a number of different approaches to health care financing including user fees and alternative compensation methods for physicians. The paper highlights documented information from Canada and international experience on the implementation issues involved. The paper evaluates the desirability of implementing these approaches in Canada.Alternative physician reimbursement models, Capitation, DALE, Disability Adjusted Life Expectancy, QAHE, Quality-Adjusted Health Expenditures, QAHE Index, SID, Supplier-Induced Demand

The article was made available through the Brunel University Open Access Publishing Fund.BACKGROUND: In interphase nuclei of a wide range of species chromosomes are organised into their own specific locations termed territories. These chromosome territories are non-randomly positioned in nuclei which is believed to be related to a spatial aspect of regulatory control over gene expression. In this study we have adopted the pig as a model in which to study interphase chromosome positioning and follows on from other studies from our group of using pig cells and tissues to study interphase genome re-positioning during differentiation. The pig is an important model organism both economically and as a closely related species to study human disease models. This is why great efforts have been made to accomplish the full genome sequence in the last decade. RESULTS: This study has positioned most of the porcine chromosomes in in vitro cultured adult and embryonic fibroblasts, early passage stromal derived mesenchymal stem cells and lymphocytes. The study is further expanded to position four chromosomes in ex vivo tissue derived from pig kidney, lung and brain. CONCLUSIONS: It was concluded that porcine chromosomes are also non-randomly positioned within interphase nuclei with few major differences in chromosome position in interphase nuclei between different cell and tissue types. There were also no differences between preferred nuclear location of chromosomes in in vitro cultured cells as compared to cells in tissue sections. Using a number of analyses to ascertain by what criteria porcine chromosomes were positioned in interphase nuclei; we found a correlation with DNA content.This study is partly supported by Sygen International PLC
Assessing malaria attributed mortality in west and southern Africa
No full textMalaria has persistently remained a serious health and socio-economic problem in developing nations particularly in Sub-Saharan Africa (SSA). There are approximately 500 million cases of malaria each year and close to one million deaths occurring mainly among children under five years. Developing countries spend a reasonable proportion of their gross domestic product (GDP) on malaria which in the end hinders their levels of development.
World Health Organizations (WHO) and partners through the Roll Back Malaria initiative (RBM) have targeted vector control, health promotion and case management (using rapid diagnostic tests and treatment with Artemisinin combination therapy) in order reduce malaria morbidity and mortality cases. Since 2002, funds for promoting malaria control activities have increased exponentially in SSA. Major donors include presidential malaria initiative (PMI) and Global fund to fight AIDS, tuberculosis and malaria (GFATM). Countries which have scaled up the recommended malaria control strategies such as insecticides-treat net (ITN) and treatment of confirmed cases have reported a decline in both morbidity and mortality especially among children. However, these statistics are based on health facilities data and yet in most developing countries many deaths occur at home and are never recorded due to inefficient vital registration systems. Monitoring the progress of such interventions requires reliable sources of data on both the transmission and infection outcome.
In malaria endemic areas, people acquire natural immunity during the early years of their life after getting exposed to repeated infections. This is observed from the reductions in the number of severe malaria-related morbidity and mortality cases especially in children >5 years. Due to the current undertakings that are aimed at reducing malaria exposure, there are concerns about shifting the disease burden to older children but the required to data to monitor this are not readily available in SSA. Low income countries have resorted to health and demographic surveillance systems (HDSS) to monitor routinely population changes and health outcomes within a defined geographical area.
In 2000, the INDEPTH, a network of HDSS integrated the Malaria Transmission Intensity and Mortality Burden Across Africa (MTIMBA) project into selected sites’ routine activities in order to assess the transmission-malaria mortality relationship taking into account the current interventions. Mortality data and other demographic characteristics were extracted from routinely collected HDSS databases. The entomological data were collected every fortnight from randomly sampled compounds over the 3 years MTIMBA period.
The MTIMBA project generated large geostatistical data that are correlated in space and time. Furthermore, the project captured longitudinal mosquito data that were characterized by many zeros especially during the dry periods. The zeros are due empty traps from a compound or when all the captured mosquitoes are not infectious. Appropriate data analysis therefore should apply models that account for spatial-temporal correlation and the excess zeros in order to avoid over or underestimation of parameters. Zero-inflated geostatistical models account for spatial-temporal correlation by introducing location-specific and time interval random effects which creates more parameters to estimate. Bayesian models implemented via Markov chain Monte Carlo simulation (MCMC) addresses fit of highly parameterized models.
This work applied zero-inflated Bayesian models to estimate malaria attributable mortality across all age-groups using large, correlated and sparse data collected from Navrongo and Manhiça HDSS between 2001 and 2004. The contributions of this thesis were (i) the description of the HDSS data characteristics and relevant methods for analysis; (ii) the spatially explicit estimates of malaria transmission intensity at monthly intervals; and (iii) the relationship between all-cause mortality and malaria transmission intensity across all age categories.
Chapter 2 described the characteristics of the MTIMBA data. These are large geostatistical, temporal, seasonal and zero-inflated data. The mortality and mosquito data were misaligned because they were captured at different compounds and time periods. Zero-inflated Bayesian spatio-temporal models are the state-of-art in handling such data. The rigorous statistical process was demonstrated by modelling sporozoite rate (SR) data from Manhiça HDSS. The analysis of the MTIMBA data was used as an avenue for building SSA capacity through course work, seminars and mentorship. Site-specific analyses are still on-going. However, the project generated data that is relevant for assessing within and between site malaria transmission heterogeneity.
The Navrongo malaria exposure surfaces described in chapter 3 were obtained from zero-inflated geostatistical models fitting separately the binomial SR data and negative binomial count data by mosquito species. All the models included space and time correlation in addition to the Climate, environmental and seasonality covariates. The entomological inoculation rate (EIR) estimates were derived as a product of predicted man biting rate and SR. Observed EIR in this district was >100 infective bites/person/year. Distance to water to bodies, day temperatures and vegetation were the main predictors of mosquito densities for the two species. The EIR maps clearly indicated that the temporal heterogeneity was stronger than the spatial variation in this area. The same situation was also observed from the analyses of the two MTIMBA sites of Rufiji (Tanzania) and Kisumu (Kenya).
Monthly malaria exposure surfaces (chapter 3) were linked to the nearest compounds where mortality was observed as described in chapter 4. Time to death data were split at monthly intervals in order to generate Bernoulli and binomial data that were modelled via logistic regression formulations. Spatio-temporal models were fitted to obtain age-specific mortality risk estimates. The model considered 2 covariates; natural logarithm transformed EIR estimates with their measurement errors and age. ITN variable was only included in neonates, post-neonates and child models. The analysis showed a positive log-linear relationship between all-cause mortality and malaria exposure in all the age groups but the association was only important among children (1-4 years) and people >= 60 years. ITN use showed a protective effect among all the under five children, confirming what was observed in Rufiji and Kisumu HDSS.
The methods used in estimating malaria exposure surfaces and mortality risks in chapters 3 and 4 were extended to Manhiça HDSS (Mozambique) data to describe the mortality-malaria transmission relationship for this area (chapter 5). The spatio-temporal age-specific models considered EIR estimates with their measurement errors (to account for the predictive uncertainty) and age as model covariates.
The distance to the nearest water bodies was the only important common predictor of An. funestus and An. gambiae mosquito densities. Malaria transmission intensity declined consistently in this area. The Model-based results indicated a positive log-linear relationship between all-cause mortality and malaria exposure across all age groups namely; the neonates (0-28 days), post-neonates (1-11months), children (1-4years), young people (5-14 years), adults (15- 59years) and old age (>=60 years).
This work contributes to further understand of malaria-mortality relationships. A positive association between mortality and malaria exposure among the under fives is consistent with what was reported from the MTIMBA sites of Rufiji and Kisumu. Completion of the remaining site-specific analyses followed by a meta-analysis will make a great contribution to malaria epidemiology. Further work however, should consider cohort analysis in order to ascertain whether malaria control interventions have caused a shift in the age of acquired immunity
Evidence for the 125 GeV Higgs boson decaying to a pair of τ leptons
No full textOpen Access. This article is distributed under the terms of the Creative Commons Attribution License (CC-BY 4.0), which permits any use, distribution and reproduction in any medium, provided the original author(s) and source are credited.A search for a standard model Higgs boson decaying into a pair of τ leptons is performed using events recorded by the CMS experiment at the LHC in 2011 and 2012. The dataset corresponds to an integrated luminosity of 4.9 fb−1 at a centre-of-mass energy of 7 TeV and 19.7 fb−1 at 8 TeV. Each τ lepton decays hadronically or leptonically to an electron or a muon, leading to six different final states for the τ -lepton pair, all considered in this analysis. An excess of events is observed over the expected background contributions, with a local significance larger than 3 standard deviations for m H values between 115 and 130 GeV. The best fit of the observed H → τ τ signal cross section times branching fraction for m H = 125 GeV is 0.78 ± 0.27 times the standard model expectation. These observations constitute evidence for the 125 GeV Higgs boson decaying to a pair of τ leptons

A data sample corresponding to an integrated luminosity of 35 nb −1 was collected using the Compact Muon Solenoid detector at the Large Hadron Collider. The dijet transverse momentum balance, azimuthal angle correlations, and pseudorapidity distributions are studied as a function of the transverse energy in the forward calorimeters ( E 4<|η|<5.2 T ). For pPb collisions, the dijet transverse momentum ratio and the width of the distribution of dijet azimuthal angle difference are comparable to the same quantities obtained from a simulated pp reference and insensitive to E 4<|η|<5.2 T . In contrast, the mean value of the dijet pseudorapidity is found to change monotonically with increasing E 4<|η|<5.2 T , indicating a correlation between the energy emitted at large pseudorapidity and the longitudinal motion of the dijet frame. The pseudorapidity distribution of the dijet system in minimum bias pPb collisions is compared with next-to-leading-order perturbative QCD predictions obtained from both nucleon and nuclear parton distribution functions, and the data more closely match the latter
