When we were designing and planning for this book, a few quick questions came to our mind: how could we transform new knowledge into practice? How important were infrastructural issues in supply chains? Were there any key research topics that have been seriously neglected in previous books publication? Were active scholars participating in research dedicated to industrial practitioners? Indeed, these are core objectives of applied research that can contribute to academic, industry and community in an ever- changing world.
This book addresses the role of supply chain in the global economy and organizations. Although global supply chain management is critical with different stakeholders within policymakers, students, researchers, logistics associations, participators, even for governmental actors who need to make strategic decisions in sustaining economic competitiveness for their countries and citizens, the core topics are often overlooked. Understanding such deficiency, we strive to include interesting, innovative, and timely topics. The contents may be similar, but different readers may have diversified expectations. Industrial practitioners may look for insight to generate appropriate strategic decisions; students and researchers may look for new ideas to develop new research areas and secure research grants; policymakers may look for best practices that will help them to develop appropriate public policies; logistics associations may look for new knowledge to review their professional training programs that align with international academic/ professional standards. Taking three years to complete this book (from writing the proposal to its final publication), we based it on four main principles, namely, “clarity” (which makes it simple for readers to comprehend), “richness” (which identifies questions from various academic experiences and disciplines to encourage readers to find out possible unexplored research or key issues), “innovations” (which stimulates readers to reflect on changing traditional, day- to- day operations for enhancement) and “practicality” (which equips learners with the skills and knowledge to work in the real world).
This book offers fundamental knowledge with many practical cases that can fulfill the needs and expectations of different parties. Readers can get invaluable insight on the future direction of supply chain development.
Metal carbonyls are important for chemical vapor deposition (CVD) of metals and alloys and formation of high surface area metallic particles which have potential applications as catalysts. Rhodium carbonyl [Rh6(CO)16] produces high surface area metallic particles whose structure has been reported as monoclinic (I2/a) with lattice dimensions, a=17.00(±0.03)Å, b=9.78(±0.02)Å, c=17.53(±0.03)Å and β=121°45' ± 30' at room temperature. Generally, metal carbonyl crystals dissociate under vacuum as carbonyl gas and decompose to metallic crystals and carbon monoxide at higher temperatures. However, the behavior of rhodium carbonyl crystals is different; they decompose directly to metallic rhodium without the formation of rhodium carbonyl gas in vacuum. Several residual fine grains of rhodium metal are found after the decomposition in vacuum at relatively low temperatures. The metallic samples of rhodium were obtained from vapor pressure experiments using torsion Knudsen-effusion apparatus. X-ray diffraction analyses performed on these grains showed severely broadened Bragg reflections indicative of small particle size and/or lattice microstrain. In this study, a comparison of lattice strains and domain sizes obtained by integral breadth and Fourier methods has been made. In addition a comparison of the lattice strains and domain sizes has been made between the Cauchy, Gaussian, Cauchy-Gaussian and Aqua integral breadth methods.
The conventional dependency ratio based on cohort-invariant cutoff points could overstate the true burden of population aging. Using optimal cohort-varying years of schooling and retirement age in a life-cycle model, we propose a modified definition of dependency ratio. We compare the proposed economic-demographic dependency ratio (EDDR) with the conventional definition and find that the conventional dependency ratio of the USA is projected to increase by 0.105 from 2010 to 2060, which is an over-projection of 86% when compared with the projected increase of 0.015 in the EDDR over the same period. Sensitivity analysis suggests that our finding is quite robust to reasonable changes in parameter values (except for one parameter), and the magnitude of over-projection ranges mainly from 0.079 to 0.102 (i.e., 75% to 97%). We follow the well-established Lee–Carter model to forecast stochastic mortality and employ the method of expanding duration to decompose the sources of over-projection.
Pharyngeal pouch surgical treatments can be carried out via an endoscopic or open approach. Injection of botulinum toxin into the cricopharyngeus was first described as an alternative treatment to the more invasive surgical procedures performed for cricopharyngeal dysfunction. It has not been previously described as a treatment option for pharyngeal pouch.
To compare operative time, average stay, complication rates and symptom control between endoscopic laser diverticulotomy, botulinum toxin injection and open procedures for pharyngeal pouch patients.
The medical records for 66 pharyngeal pouch procedures, carried out on 47 patients treated between 2011 and 2017, were identified and reviewed.
The mean operative time was 21 minutes for botulinum toxin injection, 38 for endoscopic laser diverticulotomy and 104 for open surgery. The mean hospital stay was 0.6 days for botulinum toxin injection, 4.7 for endoscopic laser diverticulotomy and 4 for open surgery. The improvement in Reflux Symptom Index scores was statistically significant for both endoscopic laser diverticulotomy and botulinum toxin injection. Botulinum toxin injection had a 0 per cent complication rate.
Botulinum toxin injection is a safe and effective treatment for pharyngeal pouch.
Discrepancies between population-based estimates of the incidence of psychotic disorder and the treated incidence reported by early psychosis intervention (EPI) programs suggest additional cases may be receiving services elsewhere in the health system. Our objective was to estimate the incidence of non-affective psychotic disorder in the catchment area of an EPI program, and compare this to EPI-treated incidence estimates.
We constructed a retrospective cohort (1997–2015) of incident cases of non-affective psychosis aged 16–50 years in an EPI program catchment using population-based linked health administrative data. Cases were identified by either one hospitalization or two outpatient physician billings within a 12-month period with a diagnosis of non-affective psychosis. We estimated the cumulative incidence and EPI-treated incidence of non-affective psychosis using denominator data from the census. We also estimated the incidence of first-episode psychosis (people who would meet the case definition for an EPI program) using a novel approach.
Our case definition identified 3245 cases of incident non-affective psychosis over the 17-year period. We estimate that the incidence of first-episode non-affective psychosis in the program catchment area is 33.3 per 100 000 per year (95% CI 31.4–35.1), which is more than twice as high as the EPI-treated incidence of 18.8 per 100 000 per year (95% CI 17.4–20.3).
Case ascertainment strategies limited to specialized psychiatric services may substantially underestimate the incidence of non-affective psychotic disorders, relative to population-based estimates. Accurate information on the epidemiology of first-episode psychosis will enable us to more effectively resource EPI services and evaluate their coverage.
