Introduction We developed and validated a new parsimonious scale to measure stoic beliefs. Key domains of stoicism are imperviousness to strong emotions, indifference to death, taciturnity and self-sufficiency. In the context of illness and disease, a personal ideology of stoicism may create an internal resistance to objective needs, which can lead to negative consequences. Stoicism has been linked to help-seeking delays, inadequate pain treatment, caregiver strain and suicide after economic stress. Methods During 2013-2014, 390 adults aged 18+ years completed a brief anonymous paper questionnaire containing the preliminary 24-item Pathak-Wieten Stoicism Ideology Scale (PW-SIS). Confirmatory factor analysis (CFA) was used to test an a priori multidomain theoretical model. Content validity and response distributions were examined. Sociodemographic predictors of strong endorsement of stoicism were explored with logistic regression. Results The final PW-SIS contains four conceptual domains and 12 items. CFA showed very good model fit: root mean square error of approximation (RMSEA)=0.05 (95% CI 0.04 to 0.07), goodness-of-fit index=0.96 and Tucker-Lewis Index=0.93. Cronbach's alpha was 0.78 and ranged from 0.64 to 0.71 for the subscales. Content validity analysis showed a statistically significant trend, with respondents who reported trying to be a stoic 'all of the time' having the highest PW-SIS scores. Men were over two times as likely as women to fall into the top quartile of responses (OR=2.30, 95% CI 1.44 to 3.68, P<0.001). ORs showing stronger endorsement of stoicism by Hispanics, Blacks and biracial persons were not statistically significant. Discussion The PW-SIS is a valid and theoretically coherent scale which is brief and practical for integration into a wide range of health behaviour and outcomes research studies

Spatial-temporal evolution of the current filamentation instability
No full textThe spatial-temporal evolution of the purely transverse current filamentation instability is analyzed by deriving a single partial differential equation for the instability and obtaining the analytical solutions for the spatially and temporally growing current filament mode. When the beam front always encounters fresh plasma, our analysis shows that the instability grows spatially from the beam front to the back up to a certain critical beam length; then the instability acquires a purely temporal growth. This critical beam length increases linearly with time and in the non-relativistic regime it is proportional to the beam velocity. In the relativistic regime the critical length is inversely proportional to the cube of the beam Lorentz factor gamma(0b). Thus, in the ultra-relativistic regime the instability immediately acquires a purely temporal growth all over the beam. The analytical results are in good agreement with multidimensional particle-in-cell simulations performed with OSIRIS. Relevance of the current study to recent and future experiments on fireball beams is also addressed1541sciescopu

Social entrepreneurship, governmentality & the Left
No full textThis paper offers a critique of the location of social entrepreneurship in the imaginaries of an advanced liberal social economy . Social entrepreneurship is used in a broad sense to refer to innovative, sustainable solutions to social problems, and this paper is agnostic towards organisational structures or the use of earned income which might be understood to circumscribe the practice of social enterprise. This chapter therefore, rejects Reiss’ (1999,1) assertion that social entrepreneurship refers simply to the “application of sound business practices to the operation of non-profit organizations” and is closer to the social innovation school of thought advocated by Dees & Anderson (2006). By doing so, the author asserts the need for nation states to take an active role through policy innovation and the co-ordination of the social economy
Chitosan-hydroxyapatite Drug Delivery System in Root Canal Filling and Delivery
No full textA root canal is one of the major components of a tooth. It is a long passage full of soft tissues, deep within thg, dentin of the tooth, adjoining the pulp chamber. The major cause of root canal infection is endodontic disease. Endodontic disease is a term used for three clinical conditions, which are: pulpititis, pulpal necrosis, and periradicular periodontitis. For the treatment of these clinical conditions, disinfection of root canal and root canal filling are required. A root canal filling is a deep filling to seal the space inside the roots of tooth to avoid infection of the tooth nerve. The aim of this project was to formulate and evaluate a sustained release, biodegradable local drug delivery system (DDS) for root canal filling. Two different salts of chlorhexidine were used as model drugs. The DDS consisted of chitosan, glyceryl monooleate (GMO), and hydroxyapatite. Tripolyphosphate sodium (TPP) was used as the crosslinker. Effect of drug load (1.1, 2.5, and 4.1 % (w/w)), salt forms used (diacetate vs. digluconate), chitosan concentration (1, 2, and 4 % (w/v)), and cross-linker concentration in the formulation on the in vitro release of chlorhexidine from the delivery system was investigated. The in vitro release was carried out at 37°C in artificial saliva. Chlorhexidine was analyzed by a HPLC method. Increase in the drug load also increased the release rate of the drug from both formulations containing different salts of chlorhexidine. At three different concentrations of chitosan ranging from 1% (w/v) to 4% (w/v), the percentage release of chlorhexidine containing digluconate salt from the DDS within 24 hrs was evaluated. The drug load was kept at 1.1% (w/w). Under these conditions, in vitro release of chlorhexidine was 56.6±12.0, 46.2±7.73, 36.5±13.8 respectively. Under similar experimental conditions, at higher drug load, increase in the chitosan concentration in the formulation retarded the release by 1.3-2 fold. The free flowing property of the implant was lost beyond 4% (w/v) chitosan concentration. To further sustain the drug release, a more hydrophobic salt (diacetete) was investigated. At any particular drug load, the rate of release of chlorhexidine from the digluconate salt was found to be 2 to 3 fold higher than the diacetate salt. At a constant drug load (2.5 % w/w), the release of chlorhexidine (% w/w) from a DDS containing diacetate salt and 4% (w/w) chitosan without a cross-linker was 36.41 ±9.42. With the incorporation of different concentrations of cross-linker at 0.2% (w/w) and 0.4% (w/w) the percentage release of chlorhexidine was found to be 28.76±6.91 and 20.54±5.85 respectively. The percentage of chlorhexidine released from the implants decreased 1.7 fold when TPP concentration increased from 0.0% (w/w) to 0.4 % (w/w). A sustained-release local delivery system containing two different salts of chlorhexidine was developed and evaluated. In vitro release of chlorhexidine from such DDS was dependent upon the different salt forms of chlorhexidine, chitosan concentrations, drug load, and cross-linker concentrations in the formulation. The effects of commercially available formulation (CALG®) with and without GMO on the release of chlorhexidine for a period of 7 days were also investigated. The percentage release of chlorhexidine from the commercially available formulation was found to be 2.04±1.02. Since the percentage release of chlorhexidine was found to be inadequate, attempt was made to modify the release. Polar additives such as GMO were directly incorporated in the formulation. The percentage release of chlorhexidine increased by 2.3 folds due to the incorporation of GMO in the formulation. Even though, incorporation of GMO enhanced the release, the overall release from the commercially product was very slow. Surface topography revealed that addition of GMO to the commercially available formulation substantially changed the crystalline structure of the matrix material. Change in the microstructure and decrease in crystallinity of the matrix might contribute to a higher diffusion of drug from such a matrix.ProQuest Traditional Publishing Optionxvii, 91 page

ORCID: 0000-0002-2750-8483 (Shubham Pathak).Natural disasters have been a significant hurdle in the economic growth of middle-income developing countries. Thailand has also been suffering from recurring flood disasters and was most which are severely affected during the 2011 floods. This paper aims to identify the various factors that impact the speed of disaster recovery among the Small and Medium Enterprises (SMEs) severely affected by the floods in Pathumthani province in central Thailand, and how it is related to its speed decision of neighbours SMEs. The methodology adopts a spatial econometric model, to analysis and understand each of the chosen factors' impact. The findings include the impact of disaster resilience, mitigation and planning at the SME level as well as the government level. The absence of accurate perception of actual risk, flood insurance and disaster management planning before the 2011 floods had contributed to the severity of the impacts during the 2011 floods
