High risk clinical characteristics for subarachnoid haemorrhage in patients with acute headache: prospective cohort study

Objective To identify high risk clinical characteristics for subarachnoid haemorrhage in neurologically intact patients with headache. Design Multicentre prospective cohort study over five years. Setting Six university affiliated tertiary care teaching hospitals in Canada. Data collected from November 2000 until November 2005. Participants Neurologically intact adults with a non-traumatic headache peaking within an hour. Main outcome measures Subarachnoid haemorrhage, as defined by any of subarachnoid haemorrhage on computed tomography of the head, xanthochromia in the cerebrospinal fluid, or red blood cells in the final sample of cerebrospinal fluid with positive results on angiography. Physicians completed data collection forms before investigations. Results In the 1999 patients enrolled there were 130 cases of subarachnoid haemorrhage. Mean (range) age was 43.4 (16-93), 1207 (60.4%) were women, and 1546 (78.5%) reported that it was the worst headache of their life. Thirteen of the variables collected on history and three on examination were reliable and associated with subarachnoid haemorrhage. We used recursive partitioning with different combinations of these variables to create three clinical decisions rules. All had 100% (95% confidence interval 97.1% to 100.0%) sensitivity with specificities from 28.4% to 38.8%. Use of any one of these rules would have lowered rates of investigation (computed tomography, lumbar puncture, or both) from the current 82.9% to between 63.7% and 73.5%. Conclusion Clinical characteristics can be predictive for subarachnoid haemorrhage. Practical and sensitive clinical decision rules can be used in patients with a headache peaking within an hour. Further study of these proposed decision rules, including prospective validation, could allow clinicians to be more selective and accurate when investigating patients with headache.
Association between physical activity and cardiorespiratory factors in adolescents: a cross-sectional exploratory study

Background: Currently, under half of the adolescents reach recommended daily levels of physical activity (PA). It is known that higher levels of PA lead to higher levels of cardiorespiratory fitness (CRF) and therefore, a health-related CRF criterion value could contribute to identify the target population for primary cardiovascular disease prevention. Therefore, the aim of this study was to explore the relation between PA levels and CRF factors in healthy adolescents. Methods: A cross-sectional exploratory study with healthy adolescents aged 12-18 years old was conducted. Socio-demographic and body composition data were collected using a questionnaire. PA level was scored with the Physical Activity Index (PAI) and CRF assessment included lung function (LF) measured with spirometry and exercise tolerance measured with Incremental Shuttle Walking Test (ISWT). According to PAI scores the sample was divided in two groups: 1 (sedentary, low and moderately active); 2 (vigorously active (VA)). Descriptive statistics were applied to characterise the sample. Independent sample t-tests assessed differences between groups and simple logistic regressions identified the predictors of being VA. Results: The study included 115 adolescents (14.63±1.70 years old; 56.52% female). Adolescents presented a normal body mass index=21.19±3.14 Kg.m -2 ) and LF (forced expiratory volume in the first second (FEV 1 )=105.58±12.73% of the predicted). Significant differences were found between groups in height (G1–163.44±8.01; G2–167±8.65; p=0.024), LF (FEV 1 / forced vital capacity (FVC); G1–97.58±10.66; G2–94.04±8.04; p=0.049), ISWT distance (G1– 1089.81±214.04; G2–1173.60±191.86; p=0.038); heart rate (HR) at rest (G1– 84.61±13.68;
Exploring Loyalty Intention in the Electronic Marketplace

The objective of this paper is to reveal the factors that determine customers' loyalty intention in the electronic marketplace. Seven hypotheses were postulated based on an extensive literature review in terms of sales behaviour, trust, satisfaction and price fairness. An empirical survey was then designed and conducted. The sample comprised customers who had made purchases from the best-known electronic marketplace in Taiwan. Results indicated that the major determinants of customers' loyalty intention in the electronic marketplace were trust and satisfaction. Practical implications of how to enhance customers' loyalty intention are proposed.

Performance and Energy Evaluation of CoMD on Intel Xeon Phi Co-processors

Molecular dynamics simulations are used extensively in science and engineering. Co-Design Molecular Dynamics (CoMD) is a proxy application that reflects the workload characteristics of production molecular dynamics software. In particular, CoMD is computationally intensive with 90+% of execution time spent to calculate inter-atomic force potentials. Hence, this application is an ideal candidate for acceleration with the Intel Xeon Phi because it has high theoretical computational performance with low energy consumption. In this work, the kernel computing Embedded Atom model (EAM) forces is adapted to utilize the Intel Xeon Phi acceleration. Performance and energy are measured in the experiments that vary thread affinity, thread count, problem size, node count, and the number of Xeon Phi's per node. Dynamic voltage and frequency scaling (DVFS) is used to reduce host-side power draw during Xeon Phi accelerated phases of the application. Test results are compared against the original (host-only) implementation that uses multithreading, and energy savings as high as 30% are observed.
Clinical application of neuroimaging in epilepsy

Objective: To evaluate the use of neuroimaging in clinical practice and to assess the prevalence of detected structural abnormalities in epilepsy patients in a clinical set up. Methods: 919 outpatients were identified and the scan results reviewed. A total of 677 patients had chronic active epilepsy (88 had idiopathic generalised epilepsy (IGE), 588 had localisation related epilepsy, one had symptomatic generalised epilepsy), 57 had a single epileptic seizure, 46 were in remission, and 139 had non-epileptic attacks. Results: 391 patients had no scan (53 patients in this group had IGE, 182 had localisation related epilepsy, one had generalised symptomatic epilepsy, 18 had single epileptic attacks, 21 were in remission, 116 had non-epileptic attacks). Altogether 528 patients had a scan, the results were not available in 33, 163 had x ray computed tomography (CT) only, 178 had standard magnetic resonance imaging (MRI) (slice thickness 5 mm), and 154 had high resolution MRI (including a T1 weighted sequence with 1.5 mm thick slices). Some 252 of 495 scans (51%) were abnormal. Abnormalities were hippocampal sclerosis (n=128), atrophy or non-specific white matter lesions (n=35), vascular abnormalities (n=27), tumours (n=25), brain damage (n=24), malformations of cortical development (n=13). Excluding atrophy and non-specific white matter lesions the prevalence of detected abnormalities was 54% in localisation related epilepsy, 18% in single seizure patients, 16% in epilepsy in remission, and 0% in IGE and non-epileptic attacks. Conclusions: Abnormalities were detected in more than half of all patients with localisation related epilepsy, and in about one in five patients with single seizures or epilepsy in remission. Many patients had no scan or only CT or standard MRI. The true prevalence of structural abnormalities may be have been higher. Scanning did not add any information in patients with IGE or non-epileptic attacks.
Relationship between urban heat island phenomenon and land use/land cover changes in Jakarta - Indonesia

Land use and land-cover changes (LULCC) are one of the important causes of urban climate change, often represented by urban heat islands (UHI) in megacity areas, including Jakarta-Indonesia. The purpose of this study is to investigate the influence of LULCC on the UHI phenomenon in Jakarta city by employing the remote sensing technique. This study is significant as a means to monitor climate change due to urban development, and would be useful to urban planners.We have analyzed the LULCC and UHI phenomena in Jakarta using Landsat satellite data in 1989 and 2002. Principal methods employed in this research are unsupervised classification, overlay matrix, boxplot statistical analysis for LULCC and thermal remote sensing for surface temperature (Ts) estimation. LULCC that indicated in 1989 was dominated by vegetation (26655 ha), but in 2002 dominated by residence (27399 ha), resulting from the expansion of the residence area (3407 ha), industry (1549 ha) and waterbody (262 ha) along with the decrease of vegetation area from 26655 to 21437 ha (-5218 ha). In both 1989 and 2002, distribution of UHI with high Ts (larger than 30°C) is seen in the central area of the city where buildings, roads, and other non-vegetation surface types are dominant. The area of UHI in 1989 is around 8453 ha, but in 2002 expanded to 56834 ha. The lower surface temperature found in vegetation and waterbody areas.
Genetic similarity between staphylococcus sp isolated from human and hospital settings, and susceptibility to different antimicrobials

One hundred and forty-three samples from human hands and hospital beds were collected at a teaching hospital in the city of Ribeirão Preto/SP by swabs, and placed in BHI broth. Following a 24 h incubation period at 37°C, they were seeded on Petri dishes containing Agar “Staphylococcus Medium 110”. Colonies typical of the genus Staphylococcus were collected and stored at 4°C until tested for catalase, mannitol, hemolysis, DNAse and coagulase. Strains were analyzed by RAPD-PCR to verify their similarity, and tested for sensitivity to ten different antibiotics. From the ninety-two isolated strains, 67 (72,8%) were coagulase- negative and 25 (27,2%) coagulase-positive. Similarity analysis showed a great heterogeneity among strains, but some presented 100% similarity. Resistance to oxacilin was encountered in 39 (42%) of the strains. Two coagulase-negative strains were resistant to vancomycin, and eleven (12%) were considered multiresistant. Measures such as hand disinfection of the staff and hospital beds and rationalization of antibiotic use could contribute to decrease pathogen transmission and selection pressure, diminishing the frequency and lethality of nosocomial infections.
A study of the asymptotic properties of Lasso for correlated data

In this paper we investigate post-model selection properties of `1 penalized weighted least squares estimators in regression models with a large number of variables M and correlated errors. We focus on correct subset selection and on the asymptotic distribution of the penalized estimators. We first prove the result under the general setup when the errors have a weak dependency structure (Doukhan 1996, see [5]), and then discuss this result for a special case i.e. AR(1). For the problem of model selection, the number of regression variables M is allowed to exceed the sample size n. We further investigate the asymptotic distribution of our estimates, when M < n, and show that under appropriate choices of the tuning parameters the limiting distribution is multivariate normal. This generalizes the result of Knight and Fu (2000), see [8], obtained for regression models with independent errors, to the case of correlated errors. We also establish that if the covariance structure is unknown but an estimator, which is componentwise consistent, is used instead, then we get result same as what we would have got if the covariance structure was known.
Participatory arts, recovery and social inclusion

PurposeThere is growing evidence of the contribution participatory arts practice may make towards mental health recovery. The purpose of this paper is to examine this phenomenon by critically reviewing the relevant literature in the light of the CHIME theoretical framework that identifies the components and processes of mental health recovery.Design/methodology/approachUsing a critical realist review method, the study draws upon foundational social and psychological theories offering an analysis of the identified mental health recovery processes in relation to participatory arts activities for people that use mental health services.FindingsThis review identifies themes that permeate the categories of CHIME and are widely delivered by participatory arts in mental health projects. These themes define the essence of a recovery approach of care and are delivered, sometimes uniquely, through arts in mental health work.Originality/valueWhilst mental health outcomes are frequently sought in participatory arts projects, there is sparse theoretical evidence to under-pin such work. This review provides potential recovery outcomes through a theoretical inquiry into participatory arts and psychosocial theories.
Existence of Solutions and Star-shapedness in Generalized Minty Variational Inequalities

We consider a problem of vector variational inequalities, referred as Generalized Minty VI(f 0 ; K), in a real Banach space X, where K is a nonempty subset of X and f 0 is the lower Dini directional derivative of a real function f dened
Behavioral Intentions, Actual Behavior and the Role of Personality Traits. Evidence from a Factorial Survey Among Female Labor Market Re-Entrants.

Factorial surveys (FS) are used frequently to draw conclusions about behavior. However, in FS only behavioral intentions are measured and answering fictive situations are likely to be connected with individual personality traits. Therefore, it is unclear to what extent behavioral intentions as measured by FS and actual behavior are related. It is also unclear whether and how personality traits influence intentions and actual behavior. This paper addresses this subject matter by analyzing these research questions. The theory of planned behavior serves as the theoretical basis (Ajzen, 1991). The research questions are addressed with data from a factorial survey collected among 395 prospective female labor market re-entrants. They were asked about their willingness to accept lower wages if compensated by “positive” nonmonetary job characteristics. A follow-up study after one year also included information on actual behavior, i.e., whether the woman has found a job. The analysis reveals that women who are willing to accept “negative” job characteristics are more likely to re-enter employment, suggesting a high correlation between results from the factorial survey and actual behavior and thus external validity. Furthermore, personality traits only have a minor influence on behavioral intentions and behavior. This confounds previous non-experimental research results. However, some individual effects are different in the intentions and behavioral model, which also indicates differences between experimental and real-world settings.
Proteogenomic Analysis of Mycobacterium smegmatis Using High Resolution Mass Spectrometry

Biochemical evidence is vital for accurate genome annotation. The integration of experimental data collected at the proteome level using high resolution mass spectrometry allows for improvements in genome annotation by providing evidence for novel gene models, while validating or modifying others. Here, we report the results of a proteogenomic analysis of a reference strain of Mycobacterium smegmatis (mc2155), a fast growing model organism for the pathogenic Mycobacterium tuberculosis—the causative agent for Tuberculosis. By integrating high throughput LC/MS/MS proteomic data with genomic six frame translation and ab initio gene prediction databases, a total of 2887 ORFs were identified, including 2810 ORFs annotated to a Reference protein, and 63 ORFs not previously annotated to a Reference protein. Further, the translational start site (TSS) was validated for 558 Reference proteome gene models, while upstream translational evidence was identified for 81. In addition, N-terminus derived peptide identifications allowed for downstream TSS modification of a further 24 gene models. We validated the existence of six previously described interrupted coding sequences at the peptide level, and provide evidence for four novel frameshift positions. Analysis of peptide posterior error probability (PEP) scores indicates high-confidence novel peptide identifications and shows that the genome of M. smegmatis mc2155 is not yet fully annotated. Data are available via ProteomeXchange with identifier PXD003500.
Educational differential between beneficiaries and non-beneficiaries of Programa Bolsa Família

Programa Bolsa Família [Program to Eradicate Child Labor] – PBF – was created in 2003 to reduce inequality and extreme poverty. It was conceived as a conditioned income transfer system: in exchange for a monthly amount, families comply with a series of conditions, including keeping their children attending school regularly. The objective of this work is to observe possible consequences of this conditions for school achievement, specifically for the age-grade distortion of students whose families declared they were beneficiaries of the program, in the 2010 Census. The results show that there are important positive differences among the children benefited by PBF in comparison to those that were not, especially among those aged 8 to 11 years.

Cost effectiveness analysis of educating girls in day and boarding secondary schools in Kenya: a case study of Kericho District

Girl child education at secondary school level is highly valued by parents in Kericho District in the present time than before. This is because most parents have realized that educating a girl child is as good as educating a boy child as it leads to eradication of poverty, ignorance and diseases. However, with limited financial resources parents are forced to choose between educating their girls in day or boarding secondary schools. Thus, parents and guardians lack guiding principles on making informed decisions on the choice of schools amid limited financial resources. Girls in boarding secondary schools usually perform better in Kenya Certificate of Secondary Education Examinations than girls in day secondary schools in Kericho District. For example in the year 2007 the mean score for girls in boarding secondary schools was 7.48 while in day secondary schools it was 4.69 and in 2008 and 2009 the mean scores for girls in boarding secondary schools was 7.93 and 8.24 respectively while girls in day secondary schools the mean scores were 4.88 and 4.05 respectively. Whichever the case, the debate on cost effectiveness of educating the girl child in boarding or day secondary school has not been concluded. Therefore, the purpose of this study was to establish cost effectiveness of educating the girl child in boarding and day secondary school in Kericho District. Descriptive survey research design was used in the study. The study population consisted of 6 head teachers, 82 teachers and 150 form four girls of 2010 from 6 secondary schools. The study found that boarders performed better than day scholars. The day scholars had a mean of 3.38 while the boarders had 3.59 in the five schools in the year 2010. The study also found that it was more cost effective to educate girls in day schools compared to boarding schools. This was because parents and the government used on average Kshs. 14,804.55 to achieve the greatest level of output of a day scholar girl and Kshs 17,997.49 to achieve the greatest level of output of a girl child in boarding school. The study concluded that it was more cost effective to educate girls in day secondary schools compared to boarding secondary schools. The findings of this study are significant to parents, school administrators, planners and policy makers in the Ministry of Education in decision making on financing of education with regard to the girl child education in Kericho District.
Maxwell's approach to deriving the EM field equations in dipolar continua

Maxwell obtained his electromagnetic field equations in dipolar continua without using macroscopic averaging by defining mathematically the fields within source regions by the same potential integrals that he used to define these fields in free space outside of source regions. Maxwell illustrated this method explicitly in his derivation of the magnetostatic equations within magnets (magnetization) where he related the mathematically defined fields to fields one can measure, in principle, in free-space cavities within the magnetization. Here in this paper, we apply the same approach to obtain the general time-dependent Maxwell equations in dipolar continua and confirm by a straightforward derivation that these equations are also obtained from macroscopic averaging of the sources and fields of discrete electric and magnetic dipoles.
