    Scientific articles are a source of information for other researchers. The aim of the current study was to compare the characteristics of the transplantation related research efforts which have been published in domestic journals and Medline indexed journals from Iran between 1993 and 2003. Within the study period, 601 transplantation scientific papers had been published from Iran, either in 91 domestic (www.iranmedex.com) or international journals (www.ncbi.com) for all the biomedical articles published between 1993 and 2003 in 91 Iranian journals. The search was conducted using "transplantation" or "transplant" as key words. A printed copy of the papers (if available) was reviewed to identify the transplanted organ, study design, number of authors, and type of article. Among 601 articles, 545 (90.6%) had been published in domestic journals, and 56 (9.4%) in Medline indexed journals. Frequency of original articles was significantly higher among domestic journals (84.4% vs. 62.5%, p=0.001). The organ type was not significantly different between domestic or Medline indexed journals (61.7%, 71.4%, p=0.556). Mean author numbers was significantly less among domestic in comparison to Medline indexed journals (3.6+/-2.2 vs. 4.6+/-3.0, p=0.047). It seems that Iranian scientific database is a more important database, not only by means of quantity, but also by means of research characteristics, such as originality of research. So, domestic scientific databases should be regarded as a pool of valuable information, and should be introduced to researchers of other countries, such as Middle East Society for Organ Transplantation region.

    Over 200 volunteers were recruited through Newspaper advertisements and other means to measure the BMD of the Lumbar Spine, Femoral Neck and Whole Body of normal healthy Canadians from the Toronto Area. All these people were carefully interviewed by trained scientists or medical personnel with respect to their medical history, life style and habits. Persons with histories that will affect bone mineral status were excluded from the study. The resulting study population consisted of 137 persons. The data was used to examine, using statistical methods, the parameters which determine bone mineral status of normal persons. The DEXA and In-vivo Neutron Activation Analysis (IVNAA) data on the same persons were compared. Further, the data was used to determine the age at which peak BMD is attained in this normal population. The Measurements were made using a DEXA instrument made by Hologic Inc., Model 1000 W.

    1996-01-01

    In-Vivo Neutron Activation Analysis (IVNAA) and Dual Energy X-ray Absorptiometry (DEXA) are routinely used in our laboratory for clinical and research investigation of Bone Mineral Content (BMC) and Bone Mineral Density (BMD in g/sq.cm). These two techniques differ in many respects. IVNAA is an established technique where 49 Ca radioisotope induced by the 48 Ca(n,gamma) 49 Ca reaction is measured to determine BMC. In DEXA, two X-rays of different energies are used and based on the known attenuation characteristics of bone and soft tissue and the measured attenuated signals, the BMC is calculated. Very little radiation dose (<0.1 mSv) is given in DEXA compared to IVNAA (3 to 5 mSv). Site specific information can be obtained in the former. Although DEXA is easier to use both the techniques are in use in the investigation of Osteopenia. The BMD, a clinical useful parameter, is a function of age and not height. The body calcium content determined by IVNAA is a function of height and not age. These differences are not yet clearly understood. Work is underway to determine the influence of several factors e.g. age, weight on BMD. We are also conducting experiments to determine the peak BMC and BMD of Canadians. The role of various life styles e.g. exercise, diet, ethnicity are being investigated as a determinant of BMD and BMC. Also the effects and safety of many drugs in the treatment of osteopenia and osteoporosis are also being studied. (author)

    In Europe, there are great geographic variations in rates of osteoporotic fracture. The MEDOS study, a case-control study of hip fracture in southern Europe, demonstrated rates that in some age groups varied geographically by more than an order of magnitude. Additionally the prevalences of vertebral deforinities vary over a 3-fold range in both sexes. The incidence of hip fracture has also been shown to vary between another populations with apparently lower rates in Hong Kong and South Africa in Europe and North America. The greatest projected increases in hip fracture incidence will occur in China and South East Asia. It seems likely that the spread of fracture risk can at least be accounted for partly by differences in bone density. Bone density in later life is dependent on the maximum bone mass ('peak' bone mass) attained in early adulthood and the subsequent rate of loss. The purpose of this study was to determine whether early adult BMD varied between populations and to explore environmental and nutritional contributions to any detennined differences. The data analysed to-date demonstrate a highly significant difference in young adult bone mass across the centers. These differences are only partly attributable to differences in height and weight. By and large, low femoral neck BMD is accompanied by low spinal BMD. Femoral neck BMD appears constant between the age of 25-45 years, but this will require confirmation by further statistical analysis. The impact of family history, environmental factors and nutrition will be explored in subsequent analyses

    In order to study the toxicological mechanism of transuranic elements, such as plutonium, involved in the induction of pulmonary fibrosis, toxic effects of several inhaled dusts and mineral particles were examined in rats. Pulmonary alveolar macrophage (PAM) was responsible for retention and behavior of inhaled asbestos fibers or silica particles and their transfer to the lymph nodes. PAM exhibited prominent phagocytosis of particles, followed by a significant release of lactic dehydrogenase and beta-glucuronidase. Multinucleated or Ia-positive PAM was frequently observed in rats presenting with pulmonary fibrosis. Pulmonary fibrosis that was induced by inhaled asbestos or silica particles was associated with significant production and release of cytokines. This indicated a close correlation with inflammatory or proliferating responses of fibroblasts and lymphocytes. Such reactions observed in PAM depended on toxicity of particles involved in phagocytosis (i.e., the ability of particles to induce pulmonary fibrosis), suggesting heterogeneity in the population of PAM.

    Urinary steroid profiling is used in doping controls to detect testosterone abuse. A testosterone over epitestosterone (T/E) ratio exceeding 4.0 is considered as suspicious of testosterone administration, irrespectively of individual heterogeneous factors such as the athlete's ethnicity. A deletion polymorphism in the UGT2B17 gene was demonstrated to account for a significant part of the interindividual variability in the T/E between Caucasians and Asians. Here, the variability of urinary steroid profiles was examined in a widely heterogeneous cohort of professional soccer players. The steroid profile of 57 Africans, 32 Asians, 50 Caucasians and 32 Hispanics was determined by gas chromatography-mass spectrometry. Significant differences have been observed between all ethnic groups. After estimation of the prevalence of the UGT2B17 deletion/deletion genotype (African: 22%; Asian: 81%; Caucasian: 10%; Hispanic: 7%), ethnic-specific thresholds were developed for a specificity of 99% for the T/E (African: 5.6; Asian: 3.8; Caucasian: 5.7; Hispanic: 5.8). Finally, another polymorphism could be hypothesised in Asians based on specific concentration ratio of 5alpha-/5beta-androstane-3alpha,17beta-diol in urine. These results demonstrate that a unique and non-specific threshold to evidence testosterone misuse is not fit for purpose. An athlete's endocrinological passport consisting of a longitudinal follow-up together with the ethnicity and/or the genotype would strongly enhance the detection of testosterone abuse. Finally, additional genotyping studies should be undertaken to determine whether the remaining unexplained disparities have an environmental or a genetic origin.

    The main objective of the present study is to compare the results predicted by using either the real geometry of tubes or porous medium assumption and to assess the prediction performance of both methods. Estimating the local subcooling of the moderator in a CANDU calandria under transient conditions is one of the major concerns in the CANDU safety analysis. Therefore extensive CFD analyses have been performed for predicting the moderator temperature in a CANDU calandria or its similar shape. However most of previous studies used a porous medium assumption instead of considering the real geometry of calandria tube. A porous medium assumption has some possible weaknesses; The increased production of turbulence due to vortex shedding in the wake of the individual tubes is not considered in the turbulence model. It is difficult to identify the true effects of the outer ring of calandria tubes on the generation of the highly non-uniform flows in the reflector region. It is not clear how well the pressure loss models quantitatively represent the three-dimensional effects of the turbulent flows through the calandria tubes.

    Internal hemorrhoids are the most common cause of lower gastrointestinal bleeding. Although new anoscopic therapies are available, few comparative randomized studies have evaluated them in regard to long-term efficacy, recurrence rates, and safety. Our purpose was to compare the treatment of internal hemorrhoids with direct current (Ultroid, Cabot Medical, Langhorn, Pa.) and bipolar (BICAP, Circon ACMI, Stamford, Conn.) hemorrhoid probes. One hundred patients with symptomatic internal hemorrhoids were randomized: 50 to direct current electrocoagulation and 50 to bipolar electrocoagulation. Follow-up and treatment were at 3- to 4-weekly intervals; two to three hemorrhoid segments were treated at each session until relief of symptoms (bleeding, prolapse, and discharge) and a reduction in hemorrhoid size to grade 1 or 0 were noted. The hemorrhoids of 98% of all patients studied were grade 2 or 3; 2% of patients had grade 1 hemorrhoids and none had grade 4 hemorrhoids. At 1 year after treatment, most patients had no (69%) or only mild (23%) recurrence, and a few had severe, symptomatic (8%) hemorrhoid recurrence. A greater recurrence rate was noted after direct current treatment (34%) than bipolar treatment (29%). In contrast, rebleeding at 1 year occurred less frequently after direct current treatment (5%) than after bipolar treatment (20%). Our conclusions were as follows: (1) Both direct current and bipolar probes were effective for control of chronic bleeding from grade 1 to 3 internal hemorrhoids. (2) Bipolar probe was significantly faster than direct current probe. (3) Direct current treatment produced fewer complications than bipolar treatment (12% versus 14%). (4) Recurrence rates were low after 1 year with either device (8%).(ABSTRACT TRUNCATED AT 250 WORDS)

    Marginal and internal adaptation is critical for the success of indirect restorations. New imaging systems make it possible to evaluate these parameters with precision and non-destructively. This study evaluated the marginal and internal adaptation of zirconia copings fabricated with two different systems using both silicone replica and microcomputed tomography (micro-CT) assessment methods. A metal master model, representing a preparation for an all-ceramic full crown, was digitally scanned and polycrystalline zirconia copings were fabricated with either Ceramill Zi (Amann-Girrbach) or inCoris Zi (Dentslpy-Sirona), n=10. For each coping, marginal and internal gaps were evaluated by silicone replica and micro-CT assessment methods. Four assessment points of each replica cross-section and micro-CT image were evaluated using imaging software: marginal gap (MG), axial wall (AW), axio-occlusal angle (AO) and mid-occlusal wall (MO). Data were statistically analyzed by factorial ANOVA and Tukey test (a=0.05). There was no statistically significant difference between the methods for MG and AW. For AO, there were significant differences between methods for Amann copings, while for Dentsply-Sirona copings similar values were observed. For MO, both methods presented statistically significant differences. A positive correlation was observed determined by the two assessment methods for MG values. In conclusion, the assessment method influenced the evaluation of marginal and internal adaptation of zirconia copings. Micro-CT showed lower marginal and internal gap values when compared to the silicone replica technique, although the difference was not always statistically significant. Marginal gap and axial wall assessment points showed the lower gap values, regardless of ceramic system and assessment method used.

    BACKGROUND Sepsis is a common cause of morbidity and mortality among hospitalized patients. The prevalence of this condition has increased significantly in different parts of the world. Patients admitted to dermatology wards often have severe loss of skin barrier and use systemic corticosteroids, which favor the development of sepsis. OBJECTIVES To evaluate the prevalence of sepsis among patients admitted to a dermatology ward compared to that among patients admitted to an internal medicine ward. METHODS It is a cross-sectional, observational, comparative study that was conducted at Hospital Santa Casa de Belo Horizonte. Data were collected from all patients admitted to four hospital beds at the dermatology and internal medicine wards between July 2008 and July 2009. Medical records were analyzed for the occurrence of sepsis, dermatologic diagnoses, comorbidities, types of pathogens and most commonly used antibiotics. RESULTS We analyzed 185 medical records. The prevalence of sepsis was 7.6% among patients admitted to the dermatology ward and 2.2% (p = 0.10) among those admitted to the internal medicine ward. Patients with comorbidities, diabetes mellitus and cancer did not show a higher incidence of sepsis. The main agent found was Staphylococcus aureus, and the most commonly used antibiotics were ciprofloxacin and oxacillin. There was a significant association between sepsis and the use of systemic corticosteroids (p <0.001). CONCLUSION It becomes clear that epidemiological studies on sepsis should be performed more extensively and accurately in Brazil so that efforts to prevent and treat this serious disease can be made more effectively.

    Emotional intelligence (EI) has been identified as an important trait for healthcare students and healthcare professionals alike and is a predictor of improved work performance and patient satisfaction. In this paper, we benchmark an international cohort of radiography students and compare their scores to those of known qualified practitioner and normative data. EI scores were at commencement from radiography degree programmes at four universities in Australia, Hong Kong, Republic of Ireland and the United Kingdom using the short form of the trait EI questionnaire (TEIQue-SF), which yields a Global score and four sub-factors. In total 293 students chose to participate. For the Australian combined Irish and UK groups, there were significant differences in Global EI and three of the four sub-factors between students and qualified radiographers (Australia: students = 5.01, qualified = 5.27; P ≤ 0.01) (Irish/UK students = 5.04, qualified = 5.28; P ≤ 0.01). When compared to the UK normative data, there was a significant difference for Global EI between the UK students and the UK norm data set (students = 4.71, normative = 4.99; P ≤ 0.01). This study provides benchmarking data for an international radiography student group. The clear differences of higher EI scores for qualified practicing radiographers when compared to student score opens discussion of the impact of academic and clinical practicum as a contributing factor in EI skills development.

    1994-01-01

    Caps have been used to structurally reinforce scientific research balloons since the late 1950's. The scientific research balloons used by the National Aeronautics and Space Administration (NASA) use internal caps. A NASA cap placement specification does not exist since no empirical information exisits concerning cap placement. To develop a cap placement specification, NASA has completed two in-hangar inflation tests comparing the structural contributions of internal caps and external caps. The tests used small scale test balloons designed to develop the highest possible stresses within the constraints of the hangar and balloon materials. An externally capped test balloon and an internally capped test balloon were designed, built, inflated and simulated to determine the structural contributions and benefits of each. The results of the tests and simulations are presented.

    To compare the efficacy of 2 chemotherapeutic drug combinations as part of multimodal therapy for orbital retinoblastoma. Prospective, comparative, study. Patients with stage III retinoblastoma (International Retinoblastoma Staging System). Demographic and clinical features were recorded at presentation. Treatment consisted of a multimodal protocol with neoadjuvant chemotherapy, enucleation, orbital external-beam radiotherapy, and adjuvant chemotherapy. For chemotherapy, patients were randomized into 2 groups: group A patients were treated with vincristine, etoposide, and carboplatin (VEC) and group B patients were treated with carboplatin and etoposide, alternating with cyclophosphamide, idarubicin, and vincristine. Treatment outcomes and adverse effects were recorded. Efficacy parameters were compared between the groups. Survival probability, cause of death, and chemotherapy-related toxicity. A total of 54 children were recruited (27 in each group). The mean ± SD follow-up was 21.3±11.34 months. The overall Kaplan-Meier survival probability was 80% (95% confidence interval [CI], 0.67-0.89) and 42% (95% CI, 0.24-0.59) at 1 year and 4 years, respectively. There were 9 deaths in group A and 15 deaths in group B. The Kaplan-Meier survival probability at 1 year was similar between the groups: 81% (95% CI, 0.60-0.91) and 79% (95% CI, 0.58-0.9) for groups A and B, respectively. At 4 years, the survival probability for group A was higher (63% [95% CI, 0.41-0.79] vs. 25% [95% CI, 0.08-0.46] for groups A and B, respectively), with a strong trend of better survival in group A over time (P = 0.05). The major cause of death was central nervous system relapse (8 patients in group A and 7 patients in group B). Two patients in group B died of sepsis after febrile neutropenia. Grade 3 and grade 4 hematologic toxicities were more common in group B, with a significant difference in grade 4 neutropenia (P = 0.002). This study compared the outcomes of VEC chemotherapy with a 5

    2015-12-01

    Full Text Available In order to avoid battery failure, a battery management system (BMS is necessary. Battery state of charge (SOC and state of health (SOH are part of information provided by a BMS. This research analyzes methods to estimate SOH based lithium polymer battery on change of its internal resistance and its capacity. Recursive least square (RLS algorithm was used to estimate internal ohmic resistance while coloumb counting was used to predict the change in the battery capacity. For the estimation algorithm, the battery terminal voltage and current are set as the input variables. Some tests including static capacity test, pulse test, pulse variation test and before charge-discharge test have been conducted to obtain the required data. After comparing the two methods, the obtained results show that SOH estimation based on coloumb counting provides better accuracy than SOH estimation based on internal ohmic resistance. However, the SOH estimation based on internal ohmic resistance is faster and more reliable for real application

    Although the US has lagged behind international developments in health technology assessment (HTA), renewed interest in HTA in the US has been fueled by the appropriation of $1.1 billion comparative effectiveness research (CER) in 2009 and the debate over health care reform. To inform CER practices in the US, we present case studies of HTA from England/Wales and Germany: contrasting methods; relevance to the US; and impact on innovation. The National Institute of Health and Clinical Excellence (NICE) was established in 1999 to inform trusts within the National Health Service of England and Wales. It uses cost-effectiveness analysis to guide the allocation resource across preventative and curative interventions. In Germany, the Institut für Qualität und Wirtschaftlichkeit im Gesundheitswesen (IQWiG) was established in 2004 to inform reimbursement and pricing policies for the statutory sickness funds set by the Gemeinsamer Bundesaursschuss (G-BA). IQWiG evaluates competing technologies within specific therapeutic areas, placing more weight on clinical evidence and the relative efficiency of competing therapies. Although having deep political and cultural antecedents, differences between NICE and IQWiG can be explained by perspective: the former guiding resource allocation across an entire system (macro-evaluation), the latter focusing on efficiency within the bounds of a particular therapeutic area (micro-evaluation). Given the decentralized nature of the US health care system, and the relative powers of different medical specialties, the IQWiG model presents a more suitable case study to guided CER efforts in the US.

    2011-10-01

    To compare the diagnostic accuracy of digital radiography with that of digital subtraction radiography in the detection of simulated internal resorption cavities. Simulated internal resorption cavities of varying sizes were created using round burs in 18 single-rooted teeth with visible pulp chamber, which had been extracted from dentate dry mandibles and split into two halves in a mesio-distal direction. Resorption cavities were created in the buccal half of the root in the cervical, middle, and apical third. Digital radiographs were taken from three different horizontal view angles before and after the creation of the cavities. This process was followed by digital subtraction radiography to evaluate their detection. Seven experienced observers and all specialists in endodontics were asked to examine the digital and digital subtraction images for the presence of the cavities. The data were analyzed using SPSS 14. The overall sensitivity of digital subtraction radiography was superior to digital radiography and with statistically better results for all cavities regardless of their location (cervical, middle, apical third) (P < 0.05). The detection of the cavities was affected by the root third in which they were located. Cavities in the apical third were more easily detected compared with those in the middle or cervical third of the root. Small-sized lesions (0.5 mm, 0.6 mm) in the middle and apical third were more frequent and more easily detected using subtraction imaging. Digital subtraction radiography is superior to digital radiography for the detection and monitoring of the progress of internal root resorption. © 2011 John Wiley & Sons A/S.

    Full Text Available Abstract Background The consistent finding of higher prevalence of hypertension in US blacks compared to whites has led to speculation that African-origin populations are particularly susceptible to this condition. Large surveys now provide new information on this issue. Methods Using a standardized analysis strategy we examined prevalence estimates for 8 white and 3 black populations (N = 85,000 participants. Results The range in hypertension prevalence was from 27 to 55% for whites and 14 to 44% for blacks. Conclusions These data demonstrate that not only is there a wide variation in hypertension prevalence among both racial groups, the rates among blacks are not unusually high when viewed internationally. These data suggest that the impact of environmental factors among both populations may have been under-appreciated.

    This study presents the results of the critical reviews, analysis, and comparison of the regulatory infrastructures for radiation and nuclear safety of Malaysis and the Philippines usi ng the IAEA safety requirements, GSR Part 1, G overnment, Legal and Regulatory Framework for Safety'' as the main basis and in part, the GSR Part 3, R adiation Protection and Safety of Radiation Sources: International Basic Safety Standards . The scope of the comparison includes the elements of the relevant legislations, the regulatory system and processes including the core functions of the regulatory body (authorization, review and assessment, inspection and enforcement, development of regulations and guides); and the staffing and training of regulatory body. The respective availabe data of the Malaysian and Philippine regulatory infrastructures and current practices were gathered and analyzed. Recommendations to fill the gaps and strengthen the existing regulatory infrastructure of each country was given using as bases relevant IAEA safety guides. Based on the analysis made, the main findings are: the legislations of both countries do not contain al the elements of teh national policy and strategy for safety as well as those of teh framework for safety in GR Part I. Among the provision that need to be included in the legislations are: emergency planning and response; decommissioning of facilities safe management of radioactive wastes and spent fuel; competence for safety; and technical sevices. Provisions on coordination of different authorities with safety responsibilities within the regulatory framework for safety as well as liaison with advisory bodies and support organizations need to be enhanced. The Philippines needs to establish an independent regulatory body, ie. separate from organizations charged with promotion of nuclear technologies and responsible for facilitiesand activities.

    Devulcanization of ground tire rubber (GTR) was done using twin screw extruder (TSE) and internal mixer (IM). Processing parameters were varied to analyze its effect on gel content. Fourier Transform Infrared Spectroscopy (FTIR) analysis was performed as qualitative technique to confirm structural change. The devulcanized rubbers with the least gel content percentage produced in both TSE and IM were then used as filler in natural rubber (NR)/coconut coir (CC) composite preparation. Effects of gel content percentage on NR/CC composite tensile strength and elongation at break were analyzed. The results show that the gel content decreased by 41% for sample processed in TSE and 50% in IM compared to control sample. Overall, the devulcanization is influenced by high energy generated by thermal or thermo-mechanical process. FTIR spectra show chemically structural changes of GTR as C=C, CH2, CH3 with higher intensity for IM sample than its counterpart indicated devulcanization. The replacement of GTR to DGTR on NR/CC/GTR composites provided less network structures and resulted better tensile strength and elongation at break.

    2017-01-01

    Full Text Available Introduction: The femoral neck fracture is a frequent pathology in the elderly population, with about of 100,000 cases per year in Brazil. The surgical treatment by internal fixation or arthroplastic hip replacement is advocated today. The non-surgical treatment is reserved for cases of exception. Objective: To compare the quality of patient postoperative life treated for femoral neck fracture by two different techniques: hip arthroplasty and internal fixation. Methods: Through the SF-36 questionnaire, we study the quality of life of 60 patients with more than 65 years, treated between 2004 and 2012 in our service. Half of the patients was submitted to internal fixation and the other half to the arthroplastic replacement. Results: Higher averages in the large majority of the parameters of the questionnaire were obtained by the group which was carried out by internal fixation, but without statistical significance in most of these differences. Some international reports indicate that patients who have suffered a fracture of the femoral neck and were treated with internal fixation may recover the quality of life they had before the fracture. Paradoxically, there is a growing trend among orthopedic surgeons to perform a hip replacement surgery in these cases. Conclusion: Further studies are needed to define which is the best surgical treatment option.

    Against the backdrop of demographic change and economic reconfiguration, recruiting international students, especially those at tertiary level, has drawn growing attention from advanced economies as part of a broad strategy to manage highly skilled migration. This comparative study focuses on three English speaking countries receiving international students: Canada, the United States, and the United Kingdom. International student policies, in particular entry and immigration regulations, and the trends in student mobility since the late 1990s are examined drawing on secondary data. By exploring the issue from the political economy perspectives, this study identifies distinct national strategies for managing student mobility, determines key factors shaping the environment of student migration in each nation, and addresses the deficiency of human capital theory in the analysis of global competition for high skills.

    Flooding is assessed as the most important natural hazard in Europe, causing thousands of deaths, affecting millions of people and accounting for large economic losses in the past decade. Little is known about the damage processes associated with extreme rainfall in cities, due to a lack of accurate, comparable and consistent damage data. The objective of this study is to investigate the impacts of extreme rainfall on residential buildings and how affected households coped with these impacts in terms of precautionary and emergency actions. Analyses are based on a unique dataset of damage characteristics and a wide range of potential damage explaining variables at the household level, collected through computer-aided telephone interviews (CATI) and an online survey. Exploratory data analyses based on a total of 859 completed questionnaires in the cities of Münster (Germany) and Amsterdam (the Netherlands) revealed that the uptake of emergency measures is related to characteristics of the hazardous event. In case of high water levels, more efforts are made to reduce damage, while emergency response that aims to prevent damage is less likely to be effective. The difference in magnitude of the events in Münster and Amsterdam, in terms of rainfall intensity and water depth, is probably also the most important cause for the differences between the cities in terms of the suffered financial losses. Factors that significantly contributed to damage in at least one of the case studies are water contamination, the presence of a basement in the building and people's awareness of the upcoming event. Moreover, this study confirms conclusions by previous studies that people's experience with damaging events positively correlates with precautionary behaviour. For improving future damage data acquisition, we recommend the inclusion of cell phones in a CATI survey to avoid biased sampling towards certain age groups.

    Reports of food-related incidents, such as cows infected with bovine spongiform encephalopathy (2001) and the Fukushima nuclear accident (2011), engendered significant fear among Japanese consumers and led to multiple farmer suicides, even when no actual health damage occurred. The growing availability of genetically modified (GM) food is occurring against this backdrop of concern about food safety. Consumers need information to assess risk and make informed purchasing decisions. However, we lack a clear picture of Japanese consumer perceptions of GM food. This study aims to understand Japanese consumer perceptions of GM food for risk communication. Consumer perceptions of GM food were compared among 4 nations. A Web-based survey was conducted in Japan, the United States, the United Kingdom, and France. Participants were asked about demographics, fear of health hazards, resistance to GM and breeding-improved products, perception of GM technology and products, and willingness to pay. Multiple linear regression analyses were conducted, as were t tests on dichotomous variables, and 1-way analysis of variance and post hoc tests. Of 1812 individuals who agreed to participate, 1705 (94%) responded: 457 from Japan and 416 each from France, the United States, and the United Kingdom. The male/female and age group ratios were all about even. Some resistance to GM food was seen in all countries in this study. France showed the strongest resistance (Pfood.

All the players of Indian team and the players of Brazil team, who came for FIVB Men Volleyball World Championship held at Pune in August 2009, were selected for the study. They were administered the Cattell’s 16 PF questionnaire. The results wereanalyzed with the help of ‘t’ test which showed that there are significant differences found between Indian volleyball players and Brazilian Volleyball players on seven factors but not on nine factors of 16 PF Questionnaire. Indian players scored high on factor ‘F’, factor ‘I’ and factor ‘M’ whereas Brazilian players have scored high on factor ‘B’, factor ‘G’, factor ‘H’ and factor ‘L’. Indian players scored low on Factor B which means that they tend to be slow to learn and grasp and they were dull as compared with Brazilian team, and gives concrete and literal interpretation. This dullness simply represents poor functioning.

    Full Text Available Albumin fusion technology, the combination of small molecular proteins or peptides with human serum albumin (HSA, is an effective method for improving the medicinal values of natural small molecular proteins or peptides. However, comparative studies between HSA-fusion proteins or peptides and the parent small molecules in biological and molecular mechanisms are less reported. In this study, we examined the binding property of two novel somatostatin-HSA fusion proteins, (SST142-HSA and (SST282-HSA, to human SSTRs in stably expressing SSTR1-5 HEK 293 cells; observed the regulation of receptor internalization and internalized receptor recycling; and detected the receptors activation of HSA fusion proteins in stably expressing SSTR2- and SSTR3-EGFP cells. We showed that both somatostatin-HSA fusion proteins had high affinity to all five SSTRs, stimulated the ERK1/2 phosphorylation and persistently inhibited the accumulation of forskolin-stimulated cAMP in SSTR2- and SSTR3-expressing cells; but were less potent than the synthetic somatostatin-14 (SST-14. Our experiments also showed that somatostatin-HSA fusion proteins did not induce the receptors internalization; rather, they accelerated the recycling of the internalized receptors induced by SST-14 to the plasma membrane. Our results indicated that somatostatin-HSA fusion proteins, different from SST-14, exhibit some particular properties in binding, regulating, and activating somatostatin receptors.

    Anterior external fixation for pelvic ring fractures has shown to effectively improve stability and reduce mortality. However, these fixators can be associated with substantial morbidity such as pin tract infection, premature loss of fixation, and decreased quality of life in patients. Recently, two new methods of subcutaneous anterior pelvic internal fixation have been developed; the INFIX and the Pelvic Bridge. These methods have the purported advantages of lower wound complications, less surgical site pain, and improved quality of life. We sought to investigate the measured distances to critical anatomic structures, as well as the qualitative and topographic differences notable during implantation of both devices in the same cadaveric specimen. The Pelvic Bridge and INFIX were implanted in eleven fresh cadavers. Distances were then measured to: the superficial inguinal ring, round ligament, spermatic cord, lateral femoral cutaneous nerve (LFCN), femoral nerve, femoral artery, and femoral vein. Observations regarding implantation and topography were also recorded. The INFIX had greater measured distances from all structures except for the LFCN, in which its proximity placed this structure at risk. Neither device appears to put other critical structures at risk in the supine position. Significant implantation and topographic differences exist between the devices. The INFIX application lacked "safety margins" concerning the LFCN in 10/11 (90.9%) specimens, while Pelvic Bridge placement lacked "safety margins" with regard to the right superficial ring (1/11, 9%) and the right spermatic cord (1/11, 9%). Both the Pelvic Bridge and INFIX lie at safe distances from most critical pelvic structures in the supine position, though INFIX application places the LFCN at risk. Copyright © 2017 Elsevier Ltd.

    Full Text Available OBJECTIVE: The aim of this study is to find out if an ultrasound technique has advantages over the conventional landmark technique. METHODS: This is a prospective randomized comparative study on 120 patients requiring central venous cannulation of the right internal jugular vein. The study comprised of two groups: ultrasound and landmark groups, each consisting of 60 patients. The outcome measures were compared between the groups. RESULTS: Cannulation of the internal jugular vein was successful in 58 patients in the ultrasound group and in 53 in the landmark group. The number of attempts was 1.5 (1 - 3 and 2 (1 - 3 in the ultrasound and landmark group respectively (p = 0.001. The time taken for the successful cannulation was 4.9 +/- 1.7 minutes in the ultrasound approach and 8.0 +/- 2.8 minutes in the landmark approach (p = 0.00. The internal jugular vein diameter in the supine position was 11.2 +/- 1.5 mm which increased to 15.04 +/- 1.5 mm with a 15 degrees head-down position in the USG group (p = 0.001. The first attempt success rate was 39/60 (63% in the ultrasound group and 19/60 (32% with the landmark technique. The seven (12% failure cases in the landmark group were rescued by the ultrasound technique. Inadvertent carotid artery puncture occurred in 2/60 (3% and 6/60 (10% of patients in the ultrasound and land mark group respectively. CONCLUSIONS: Ultrasound improves success rate, minimizes cannulation time and complications during internal jugular vein cannulation. It can be employed as a rescue technique in cases of a failed landmark technique. Keywords:cannulation, central, landmark, technique, ultrasound.

    Conventional radiographic evaluation of fracture healing is not a reliable method, because it depends on the examinator's experience and the quality of the exam. Therefore, serial images differing in density, contrast and geometrical projection can lead to a misdiagnosis on the postoperative fracture healing. Even in good quality images, little changes in calcified tissues often can't be visualized, because of its little sensibility and because of the limited human sight. The use of more sensitive and objective methods could increase the accuracy of this evaluation. This study intended to compare, by digitalized panoramic radiography, the mandible fracture healing after two different types of treatment: open reduction with internal fixation (group 1) and closed reduction with intermaxillary fixation (group 2). It was taken three postoperative radiographs (within a week, a month and three months after treatment), which were digitalized (600 dpi, 8 bits) and adjusted in brightness and size in Photoshop software. Then these images were evaluated by digital subtraction in ImageTool software. The results revealed greater areas of new bone formation in the internal fixation group, in all the evaluated times. Thus, open reduction with internal fixation resulted in more rapid fracture healing than closed reduction with intermaxillary fixation.

    Many regions of the world feel the pressure to interconnect electric power systems internationally. Regional integrations of the electricity sector have become part of free trade and common market initiatives, though the steps individual national jurisdictions take towards developing integrated systems vary. In this article, we review three regions concerned with common market initiatives and at different stages of integration processes that involve infrastructural, regulatory, and commercial decisions. First, we examine the North European countries in the Nordic Council, then countries in the Southern Cone of South America in MERCOSUR, and finally Mexico, the United States and Canada, linked under NAFTA. This comparative study highlights the potential, but also the many hurdles, that electricity sector integrations face. The study suggests a framework for measuring the level of electricity sector integration that could be applied to other regions.

    Open reduction and internal plate fixation of the fibula is the gold standard treatment for ankle fractures. The aim of this study was to perform a prospective randomized study to compare bone union, complications and functional results of two types of internal fixation of the fibula (plating and the Epifisa FH intramedullary nail). Inclusion criteria were: closed fractures, isolated displaced fractures of the lateral malleolus, inter- and supra-tubercular bimalleolar fractures, and trimalleolar fractures. This study included 71 patients (mean age 53 ± 19): plate fixation group (n=35) and intramedullary nail fixation group (n=36). In seven cases, intramedullary nailing was technically impossible and was converted to plate fixation (the analysis of this sub-group was performed independently). Two patients died and two patients were lost to follow-up. The final comparative series included 32 cases of plate fixation and 28 cases of intramedullary nail fixation. Union, postoperative complications and Kitaoka and Olerud-Molander functional scores were analyzed after one year of follow-up. There was no significant difference in the rate of union (P=0.5605) between the two types of fixation. There were significantly fewer complications (7% versus 56%) and better functional scores (96 versus 82 for the Kitaoka score; 97 versus 83 for the Olerud-Molander score) with intramedullary nailing than with plate fixation. Intramedullary nailing of the lateral malleolus in non-comminuted ankle fractures without syndesmotic injury is a reproducible technique with very few complications that provides better functional results than plate fixation.

    Chaston, I

    1994-02-01

    In responding to the UK government's market forces model, some National Health Service (NHS) managers have introduced private sector concepts such as 'customer care' and 'total quality management' (TQM). Private sector firms find that success of these techniques is dependent upon creating an internal marketing orientation across the entire organization. To determine how internal marketing is being applied, a comparative survey of UK service sector firms and NHS units was undertaken using a modified version of Parasuraman's SERVQUAL model. All respondents indicated existence of type 1, 2, 3 and 4 gaps in the internal customer management process within their organizations. Major influencers of service gaps include departments placing internal efficiency ahead of internal customers and insufficient understanding of internal customer requirements. The survey indicated that, in certain areas of managing service quality, the NHS is performing better than its private sector counterparts. Nevertheless, opportunity for enhancing service quality in the NHS is possible through improving the flow of information between departments, stronger orientation towards meeting customer needs, upgrading provision systems and changing intradepartmental culture. The constraint facing the NHS manager is the limited availability of resources. One solution is to allocate resources in relation to service priorities. A directional planning matrix is presented as a tool for developing an optimum internal customer management strategy within an NHS unit.

    The purpose of the present study was to ascertain comparative retention of 134 Cs or 147 Pm in skeleton on induction of chromosome aberrations and PCE's micronucleus formation in bone marrow cells. Results indicated that after iv signal nuclide 134 Cs, through 7 weeks observation, the retention data in skeleton could be well described by an exponential expression. Experiments indicated that the retention value and the absorption dose of 147 Pm in skeleton were significantly higher in comparison with 134 Cs. Both internal contamination of 134 Cs or 147 Pm could induce chromosome aberrations and PCE's micronucleus formation in bone marrow cells. Among the type of chromosome aberrations of bone marrow cells induced by 134 Cs or 147 Pm included gap, chromatid breakage, chromosome breakage and translocation. Moreover, the chromosome aberration rates were elevated when the intake of radioactivity of 134 Cs or 147 Pm were enlarged. At the same time, chromosome fragment of bone marrow cells also induced by 134 Cs or 147 Pm only through high radioactive contamination. Studies showed that chromosome translocation was appeared only through high radioactivity of 147 Pm contamination. By comparing with 1 '4 7 Pm, however, the induction of chromosome aberrations and PCE's micronucleus formation rates on bone marrow cells induced by 134 Cs was quite low

    Emerging research suggests that both perceptions of discrimination and internalized racism (i.e., endorsement of negative stereotypes of one’s racial group) are associated with poor mental health. Yet, no studies to date have examined their effects on mental health with racial/ethnic minorities in the US in a single study. The present study examined: (a) the direct effects of everyday discrimination and internalized racism on risk of DSM-IV criteria of past-year major depressive disorder (MDD); (b) the interactive effects of everyday discrimination and internalized racism on risk of past-year MDD; and (c) the indirect effect of everyday discrimination on risk of past-year MDD via internalized racism. Further, we examined whether these associations differed by ethnic group membership. We utilized nationally representative data of Afro-Caribbean (N = 1,418) and African American (N = 3,570) adults from the National Survey of American Life. Results revealed that experiencing discrimination was associated with increased odds of past-year MDD among the total sample. Moreover, for Afro-Caribbeans, but not African Americans, internalized racism was associated with decreased odds of meeting criteria for past-year MDD. We did not find an interaction effect for everyday discrimination by internalized racism, nor an indirect effect of discrimination on risk of past-year MDD through internalized racism. Collectively, our findings suggest a need to investigate other potential mechanisms by which discrimination impacts mental health, and examine further the underlying factors of internalized racism as a potential self-protective strategy. Lastly, our findings point to the need for research that draws attention to the heterogeneity within the U.S. Black population. PMID:28405176

    Full Text Available Measurement of RNA can be used to study and monitor a range of infectious and non-communicable diseases, with profiling of multiple gene expression mRNA transcripts being increasingly applied to cancer stratification and prognosis. An international comparison study (Consultative Committee for Amount of Substance (CCQM-P103.1 was performed in order to evaluate the comparability of measurements of RNA copy number ratio for multiple gene targets between two samples. Six exogenous synthetic targets comprising of External RNA Control Consortium (ERCC standards were measured alongside transcripts for three endogenous gene targets present in the background of human cell line RNA. The study was carried out under the auspices of the Nucleic Acids (formerly Bioanalysis Working Group of the CCQM. It was coordinated by LGC (United Kingdom with the support of National Institute of Standards and Technology (USA and results were submitted from thirteen National Metrology Institutes and Designated Institutes. The majority of laboratories performed RNA measurements using RT-qPCR, with datasets also being submitted by two laboratories based on reverse transcription digital polymerase chain reaction and one laboratory using a next-generation sequencing method. In RT-qPCR analysis, the RNA copy number ratios between the two samples were quantified using either a standard curve or a relative quantification approach. In general, good agreement was observed between the reported results of ERCC RNA copy number ratio measurements. Measurements of the RNA copy number ratios for endogenous genes between the two samples were also consistent between the majority of laboratories. Some differences in the reported values and confidence intervals (‘measurement uncertainties’ were noted which may be attributable to choice of measurement method or quantification approach. This highlights the need for standardised practices for the calculation of fold change ratios and

    Full Text Available Abstract Background Large-scale cross-national studies designed to measure student achievement use different social, cultural, economic and other background variables to explain observed differences in that achievement. Prior to their inclusion into a prediction model, these variables are commonly scaled into latent background indices. To allow cross-national comparisons of the latent indices, measurement invariance is assumed. However, it is unclear whether the assumption of measurement invariance has some influence on the results of the prediction model, thus challenging the reliability and validity of cross-national comparisons of predicted results. Methods To establish the effect size attributed to different degrees of measurement invariance, we rescaled the ‘home resource for learning index’ (HRL for the 37 countries ( $$n=166,709$$ n = 166 , 709 students that participated in the IEA’s combined ‘Progress in International Reading Literacy Study’ (PIRLS and ‘Trends in International Mathematics and Science Study’ (TIMSS assessments of 2011. We used (a two different measurement models [one-parameter model (1PL and two-parameter model (2PL] with (b two different degrees of measurement invariance, resulting in four different models. We introduced the different HRL indices as predictors in a generalized linear mixed model (GLMM with mathematics achievement as the dependent variable. We then compared three outcomes across countries and by scaling model: (1 the differing fit-values of the measurement models, (2 the estimated discrimination parameters, and (3 the estimated regression coefficients. Results The least restrictive measurement model fitted the data best, and the degree of assumed measurement invariance of the HRL indices influenced the random effects of the GLMM in all but one country. For one-third of the countries, the fixed effects of the GLMM also related to the degree of assumed measurement invariance. Conclusion The

    2018-04-01

    Full Text Available The economic stability is the main goal of every country’s administration, contributing to the decrease of uncertainty, creating an attractive business environment, attracting foreign direct investment and contributing to economic growth, which increases the standard of living, reduces income inequalities, represents a sustainable development for the country and puts an end to the migration process. Migration flows lower the demographic resources of the states going through this process and consequently they compromise the possibility for future generations to support a sustainable economic growth. Migration is a process with an aggressive and alarming manifestation in Romania and Bulgaria, raising the problem of the future capacity of these countries to ensure long-term economic and social sustainability and requiring an analysis framework from a scientific perspective. The current study proposes a comparative study to identify the important determinants of international migration in the EU28 and analyses the impact of remittances on economic growth/stability and income inequality in Romania and Bulgaria—Central and Eastern Europe countries—for the period between 1990 and 2015. The main contribution of the present study consists in emphasising the common determinants of the two countries regarding the migration process and at the same time providing solutions to improve government policies to contribute to the economic and social sustainability. The authors employed a multiple regression model and the correlation analysis, and tested 8 hypotheses for Romania and Bulgaria. The results indicated that the main determinants of the migration process in Romania and Bulgaria are the inflation rate, the income inequality and household consumption expenditure. Furthermore, the results indicated that there is not a direct relationship between the remittances received/capita and GDP/capita growth rate in Romania and Bulgaria. In addition, there is a

    2006-06-01

    The anatomical structure of internal sacs for embryonic incubation was studied using SEM and light microscopy in three cheilostome bryozoans-Nematoflustra flagellata (Waters,1904), Gontarella sp., and Biflustra perfragilis MacGillivray, 1881. In all these species the brood sac is located in the distal half of the maternal (egg-producing) autozooid, being a conspicuous invagination of the body wall. It consists of the main chamber and a passage (neck) to the outside that opens independently of the introvert. There are several groups of muscles attached to the thin walls of the brood sac and possibly expanding it during oviposition and larval release. Polypide recycling begins after oviposition in Gontarella sp., and the new polypide bud is formed by the beginning of incubation. Similarly, polypides in brooding zooids degenerate in N. flagellata and, sometimes, in B. perfragilis. In the evolution of brood chambers in the Cheilostomata, such internal sacs for embryonic incubation are considered a final step, being the result of immersion of the brooding cavity into the maternal zooid and reduction of the protecting fold (ooecium). Possible reasons for this transformation are discussed, and the hypothesis of Santagata and Banta (Santagata and Banta1996) that internal brooding evolved prior to incubation in ovicells is rejected.

    1993-01-01

    Thirty one patients with internal derangement of the TMJ and 12 subjects with normal TMJ were selected and their MR imaging and border movements of the mandible were recorded. In addition, the relationship between them were examined. In this study, the disk position and configuration in MR findings were classified as follows. Disk position: superior, anterior and anterolateral (medial and lateral were omitted), grade of anterior disk displacement (with and without reduction): slight, moderate and severe, disk configuration: biconcave, enlargement of posterior band, even thickness and biconvex. Border movements of the mandible were influenced not only by unilateral or bilateral interior derangement but also by with or without reduction of the disk. Border movements in patients with anterolateral disk displacement were more severely restricted than those with anterior disk displacement. Border movements were remarkably limited in patients with slight disk displacement, especially in unilateral cases with reduction of the disk. Border movements in patients with even thickness and biconvex types of disk configuration were a little restricted and rather similar to those of normal subjects. There was significant correlation between border movements and disk position and configuration. It means that measurement of the mandibular movements is very significant to diagnose the condition of internal derangements of the TMJ. (author)

    There are few studies comparing cross-cultural adaptation of migrant groups in two different cultural settings. This study compares the level of negative affect and acculturative stressors between Chinese international students in Australia and Mainland Chinese students in Hong Kong. The predictive effects of acculturative stressors and acculturative strategies on negative affect were also compared between the two groups. A total of 606 graduate students were recruited for a cross-sectional survey in Melbourne, and Hong Kong, China. The measurement included the Acculturative Hassles Scale for Chinese Students, Acculturative Strategy Scale, and Chinese Affect Scale. Independent t-tests and hierarchical regression analysis were conducted for data analysis. Chinese international students in Australia were found to encounter more acculturative stressors and experience a higher level of negative affect than their counterparts in Hong Kong. The acculturative stressor of academic work and a marginalization strategy significantly predicted negative affect in both groups. The acculturative stressor of cultural difference predicted negative affect in the Hong Kong sample, and assimilation strategy predicted negative affect in the Australian sample only. It is more difficult for Chinese international students to adapt to a host society with greater cultural distance. Cross-cultural comparative study helps to find out culture-general and culture-specific predictors of acculturation and helps design tailor-made intervention programs for international students across cultures.

    Poor bone health is a major public health problem of worldwide concern. It affects all segments of the population, but is particularly important in older people (and, most of all, in post-menopausal women). In view of the fat that the numbers of older people, both in absolute terms and as a fraction of the total population, are increasing practically everywhere, there is little doubt that poor bone health will become a much more widespread and severe problem in coming decades. Earlier in 1994 the International Atomic Energy Agency (henceforth ''the Agency'') started a 5-year Co-ordinated Research Programme (CRP) based on the recommendations of an Advisory Group Meeting (AGM) held in 1992. This CRP currently addresses on particular measure of bone health -bone mineral density (BMD). The main concept underpinning this CRP is the ideal that a major determinant of bone health in later years is peak bone mass. The objective of the Agency's CRP is to determine the age of peak bone mass in various different study groups and countries, and to investigate how BMD varies with age, sex, ethnicity and geographical origin of the subjects. Information on individual participant's plans for implementation of the CRP, and progress achieved so far on this and related topics, was presented in each country's report

    The purpose of the present study was to compare the predictive effects of acculturative stressor and meaning of life on negative affect in the process of acculturation between Chinese international students in Australia and Hong Kong. Four hundred mainland Chinese students studying at six universities in Hong Kong and 227 Chinese international students studying at the University of Melbourne in Australia completed a questionnaire that included measures of acculturative stressor, meaning of life, negative affect and demographic information. The Australian sample was found to have a higher level of acculturative stressor and negative affect than the Hong Kong sample. Acculturative stressor had a positive impact on negative affect in both samples, but the impact of different domains of acculturative stressor on negative affect varied between the two groups. Finally, meaning of life partially mediated the relationship between acculturative stressor and negative affect in the Hong Kong sample, but no such effect was found in the Australia sample. Acculturative stressor is a critical risk factor for negative affect in acculturation for Chinese international students in Australia and Hong Kong. Meaning of life acted as a protective factor that mitigated negative affect for mainland Chinese students in Hong Kong, but not for the Chinese international students in Australia. The theoretical and practical implications for resilience-based and meaning-oriented intervention for Chinese international students are discussed.

    Barriers to cervical cancer screening in low-resource settings include lack of accessible, high-quality services, high cost, and the need for multiple visits. To address these challenges, we developed a low-cost, intravaginal, optical cervical imaging device, the point-of-care tampon (POCkeT) colposcope and evaluated whether its performance is comparable with a standard-of-care colposcope. There were 2 protocols, which included 44 and 18 patients. For the first protocol, white-light cervical images were collected in vivo, blinded by device, and sent electronically to 8 physicians from high-, middle-, and low-income countries. For the second protocol, green-light images were also collected and sent electronically to the highest performing physician from the first protocol who has experience in both a high- and low-income country. For each image, physicians completed a survey assessing cervix characteristics and severity of precancerous lesions. Corresponding pathology was obtained for all image pairs. For the first protocol, average percent agreement between devices was 70% across all physicians. The POCkeT and standard-of-care colposcope images had 37% and 51% agreement with pathology for high-grade squamous intraepithelial lesions (HSILs), respectively. Investigation of HSIL POCkeT images revealed decreased visibility of vascularization and lack of contrast in lesion margins. After changes were made for the second protocol, the 2 devices achieved similar agreement to pathology for HSIL lesions (55%). Based on the exploratory study, physician interpretation of cervix images acquired using a portable, low-cost POCkeT colposcope was comparable to a standard-of-care colposcope.

Since the beginning (Israel 1978 the main goals of the Society were established under a worldwide mind set considering five continents and no discrimination of any kind. The founders wanted to compare Physical Education and Sports across the world, searching for the best practices deserving consideration and applied on the purpose of improving citizen quality of life. The mission still stands for “Compare to learn and improve”. As all the organizations lasting for 39 years, ISCPES experienced several vicissitudes, usually correlated with world economic cycles, social and sports changes, which are in ISS journal articles - International Sport Studies. ISS journal is Scopus indexed, aiming to improve its quality (under evaluation to reach more qualified students, experts, professionals and researchers; doing so it will raise its indexation, which we know it is nowadays a more difficult task. First, because there are more journals trying to compete on this academic fierce competitive market; secondly, because the basic requirements are getting more and more hard to gather in the publishing environment around Physical Education and Sports issues. However, we can promise this will be one of our main strategic goals. Another goal I would like to address on this Editorial is the language issue. We have this second strategic goal, which is to reach most of languages spoken in different continents; besides the English language, we will reach Chinese, Spanish and Portuguese speaking countries. For that reason, we already defined that all the abstracts in English will be translated into Chinese, Spanish and Portuguese words so people can find them on any search browser. That will expand the demand for our journal and articles, increasing the number of potential readers. Of course this opportunity, given by

    Full Text Available Over the last 10-20 years, comparative research in the feld of communication has almost become fashionable. Many factors are responsible for this, for example: an increased awareness of globalisation as a communication-driven process; an awareness of increased transnational conglomerization of media organizations; and the increasing use of the Internet which facilitates easier access to information around the world. But the big question is how to organize collaborative international communication research efectively? Which models of cooperation are available to us, and what are their advantages and disadvantages? In this article, I analyze fve ways of doing collaborative researches and their respective challenges.

    Full Text Available Cellular phones are used in the vicinity of a human head, which absorbs power from antenna radiation. This investigation analyzes the effects of antenna substrate materials on electromagnetic (EM absorption in a human head. Antennas are used in analysis with four different dielectric substrate materials, which are Bakelite, FR4 glass epoxy, Rogers R04003, and Taconic TLC. Moreover, two different thicknesses of each substrate are considered in the experimental setup. The EM absorption associated with two types of cell phone antennas is evaluated in the closed vicinity of the human head model. One of them is planar inverted-F antenna (PIFA, which is used as the internal handset antenna and another one is helical antenna, which is used as external handset antenna. This investigation consists of two different operating frequency bands, GSM 900 MHz and DCS 1800 MHz. The EM absorption in the human head is presented using the peak specific absorption rate (SAR and total absorbed power (TAP by the user. The finite-difference time-domain (FDTD method based on Computer Simulation Technology (CST Microwave studio is utilized in this investigation. The obtained results show that the substrate materials do not effect SAR and TAP values considerably for both antennas, but substrate thickness affects the SAR and TAP values significantly. In addition, the substrate thickness affects the SAR and TAP values significantly in most of the cases Moreover, PIFA produces lower SAR than that of a helical antenna significantly for both GSM and DCS frequency band.DOI: http://dx.doi.org/10.5755/j01.ms.22.3.8889

    Since the last RCM held in 1996, most participants have made good progress towards the objective of measuring bone mineral density (BMD) in at least 25 subjects of both sexes in each of the 5-year age ranges between 15 and 50 years (i.e. a minimum of 350 subjects in each study group). Some participants have also collected and analysed a number of bone samples, as specified in the protocols for the CRP. One of the most important tasks within the CRP is to 'normalize' the data from different DEXA machines and study centres so as to allow a meaningful comparison of the BMD measurements between centres and study groups. To this end, a European Spine Phantom (ESP) has recently been circulating among the participating centres, who have reported their results to the Central Reference Laboratory (CRL). Central evaluation of the data has so far only been done for a few of the participating centres

    Over 200 volunteers were recruited through Newspaper advertisements and other means to measure the BMD of the Lumbar Spine and Femoral Neck of normal healthy Canadians from the Toronto Area. All these people were carefully interviewed by trained scientists or medical personnel with respect to their medical history, life style and habits. Persons with histories that will affect bone mineral status were excluded from the study. The resulting study population consisted of 162 persons. The data was used to determine the age or the range of ages at which peak BMD is attained in this normal population. The Measurements were made using a DEXA instrument made by Hologic Inc., Model 1000W. (author)

    International Nuclear Information System (INIS)

    1992-01-01

    An Advisory Group Meeting convened by the IAEA in October 1992 made recommendations on the setting up of a Co-ordinated Research Programme (CRP) using nuclear and isotopic techniques for international comparative studies of osteoporosis. The proposed CRP will be implemented by the IAEA during the period 1993-1997. The main purpose of this programme is to undertake pilot studies of bone density in selected developing country populations for the purposes of (i) determining the age of peak bone mass in each study group, and (ii) quantifying differences in bone density as functions of the age and sex of persons in the study groups, as well as quantifying differences between the study groups in different countries. The preferred technique for bone density measurements in this study is DEXA (dual energy X-ray absorptiometry). Additional measurements of trace elements in bone (and possibly also teeth) are also foreseen using neutron activation analysis and other appropriate techniques

    Full Text Available Carbapenem-resistant Acinetobacter baumannii (CRAb have emerged in recent decades as major causes of nosocomial infections. Resistance is mainly due to overexpression of intrinsic and/or acquired carbapenemases, especially oxacillinases (OXA. In Italy, although the sequence type (ST 2 and the ST78 are the most frequently detected, we recently reported ST632, a single locus variant of ST2. Therefore, this study was aimed at unraveling common bacterial surface virulence factors involved in pathogenesis and antibiotic resistance in representative CRAb of these ST genotypes. Outer membrane protein (OMP composition together with motility, biofilm formation, in vitro adherence to, invasion of, and survival within pneumocytes were analyzed. Differently from the carbapenem-susceptible reference strain ATCC 17978, either overexpressed OXA-51 or both OXA-23 and OXA-51 co-purified with OMPs in CRAb. This tight association ensures their maximal concentration on the inner surface of the outer membrane to provide the best protection against carbapenems. These findings led us to propose for the first time a common behavior of OXA enzymes in CRAb. Despite the presence of both OmpA and phosphorylcholine-porinD and the ability of all the strains to adhere to cells, invasion, and survival within pneumocytes was shown only by ST2 and ST78 isolates, sharing the highest number of identified OMPs. Conversely, notwithstanding genetic and OMPs similarities with ST2, ST632 was unable to invade and survive within epithelial cells. Overall, our study shows that different STs share a specific OMP composition, also shaped by overexpressed OXA, that is needed for invasiveness and survival of CRAb.

    This contribution aims at four points.First we want to argue why we think a reflexive social science is more adequate than the orthodox consensus. In current practice much of the criticism on the orthodox consensus is shared on a theoretical level, without considering the implications and acting...... upon the consequences on the level of empirical research. We want to avoid that, so our second and third subject will be the practical implications of reflexivity for empirical research as well as for social policy. Our discussion on these subjects is based on the practical experiences in the INPART...... project, in which we have tried to deal with these consequences. Fourth, and hopefully as a result of the first three aims, we want to argue that a reflexive approach of international, comparative research is not only desirable, but attainable as well. In order to do so, we begin with a short discussion...

    2002-01-01

    In 1994, the International Atomic Energy Agency started the five-year Co-ordinated Research Project (CRP) on Comparative International Studies of Osteoporosis Using Isotope Techniques. The objectives of this study were: To harmonize the techniques of measuring BMD within the participating countries and to obtain data that can be compared between the different study groups (countries); To determine whether early adult PBM varies between populations over the age range from 15 to 50 years. In other words, to determine the age of peak bone mass in selected populations from developing countries; To explore environmental and nutritional contributions to any determined differences. Further information about the purpose and scope of the CRP may be found in the report of the Advisory Group Meeting (AGM) held in 19921 and other reports of this CRP. The fourth Research Co-ordination Meeting (RCM) for participants of the CRP, which is the subject of the present report, was held at the University of Sheffield Medical School; WHO Collaborating Center for Metabolic Bone Diseases in Sheffield, UK from 28 Feb. to 3 March 2000

    The study was to comprehensively compare the postoperative outcome and imaging parameter characters in a short/middle period between the percutaneous endoscopic lumbar discectomy (PELD) and the internal fixation of bone graft fusion (the most common form is posterior lumbar interbody fusion [PLIF]) for the treatment of adjacent segment lumbar disc prolapse with stable retrolisthesis after a previous lumbar internal fixation surgery.In this retrospective case-control study, we collected the medical records from 11 patients who received PELD operation (defined as PELD group) for and from 13 patients who received the internal fixation of bone graft fusion of lumbar posterior vertebral lamina decompression (defined as control group) for the treatment of the lumbar disc prolapse combined with stable retrolisthesis at Department of Spine Surgery, the Third Hospital of Hebei Medical University (Shijiazhuang, China) from May 2010 to December 2015. The operation time, the bleeding volume of perioperation, and the rehabilitation days of postoperation were compared between 2 groups. Before and after surgery at different time points, ODI, VAS index, and imaging parameters (including Taillard index, inter-vertebral height, sagittal dislocation, and forward bending angle of lumbar vertebrae) were compared.The average operation time, the blooding volume, and the rehabilitation days of postoperation were significantly less in PELD than in control group. The ODI and VAS index in PELD group showed a significantly immediate improving on the same day after the surgery. However, Taillard index, intervertebral height, sagittal dislocation in control group showed an immediate improving after surgery, but no changes in PELD group till 12-month after surgery. The forward bending angle of lumbar vertebrae was significantly increased and decreased in PELD and in control group, respectively.PELD operation was superior in terms of operation time, bleeding volume, recovery period, and financial

    In 1994, the International Atomic Energy Agency started the five-year Co-ordinated Research Project (CRP) on Comparative International Studies of Osteoporosis Using Isotope Techniques. The objectives of this study were: To harmonize the techniques of measuring BMD within the participating countries and to obtain data that can be compared between the different study groups (countries); To determine whether early adult PBM varies between populations over the age range from 15 to 50 years. In other words, to determine the age of peak bone mass in selected populations from developing countries; To explore environmental and nutritional contributions to any determined differences. Further information about the purpose and scope of the CRP may be found in the report of the Advisory Group Meeting (AGM) held in 19921 and other reports of this CRP. Since the last RCM held in 1998, the CRP participants have gathered up more data on BMD. Indeed 3488 subjects 15-50 years) have been recruited for the purpose of this project and have been stratified equally by sex and age into six -year age bands. Most of the participants have also completed collecting data on dietary intake, medical history, physical exercise, and lifestyle, as suggested in the VrHO questionnaire. Some participants have analyzed trace elements in a number of bone samples as well. One of the most important purposes of this CRP is to obtain harmonized data on BMD that is comparable from one study group to another. To ensure this quality insurance, the densitometers in each center were cross calibrated using a European Spine Phantom (ESP). Further-more, day-to-day control of DEXA machines was managed by each individual center. The fourth Research Co-ordination Meeting (RCM) for participants of the CRP, which is the subject of the present report, was held at the University of Sheffield Medical School; WHO Collaborating Center for Metabolic Bone Diseases in Sheffield, UK from 28 Feb. to 3 March 2000

    A comparative study of treating mature landfill leachate with various treatment processes was conducted to investigate whether the method of combined processes of internal micro-electrolysis (IME) without aeration and IME with full aeration in one reactor was an efficient treatment for mature landfill leachate. A specifically designed novel sequencing batch internal micro-electrolysis reactor (SIME) with the latest automation technology was employed in the experiment. Experimental data showed that combined processes obtained a high COD removal efficiency of 73.7 ± 1.3%, which was 15.2% and 24.8% higher than that of the IME with and without aeration, respectively. The SIME reactor also exhibited a COD removal efficiency of 86.1 ± 3.8% to mature landfill leachate in the continuous operation, which is much higher (p<0.05) than that of conventional treatments of electrolysis (22.8-47.0%), coagulation-sedimentation (18.5-22.2%), and the Fenton process (19.9-40.2%), respectively. The innovative concept behind this excellent performance is a combination effect of reductive and oxidative processes of the IME, and the integration electro-coagulation. Optimal operating parameters, including the initial pH, Fe/C mass ratio, air flow rate, and addition of H(2)O(2), were optimized. All results show that the SIME reactor is a promising and efficient technology in treating mature landfill leachate. Copyright © 2012 Elsevier B.V. All rights reserved.

    Full Text Available The aim of this paper is to map this place of economics in the field of study of Comparative and International Education. Interrelationship between economy and education is concerned, two broad lines of enquiry lie within the scope of Comparative and International Education: economy as shaping force of education systems and the effect of education on the economy. In the interwar “factors and forces” stage of Comparative Education, the economy as a shaping force of national education systems came to the fore. In the social science phase of the 1960s the focus shifted to a study of the effect of education on the economy. This was reversed again in the 1970s, when socio-economic reproduction theories assigned a deterministic place to socio-economic stratification of society. In recent years neo-liberal economics dictated the research agenda of Comparative Education. In conclusion recommendations for a future research agenda in the field are made.

    The aim of this cross-sectional study in preschool children was to assess the ability of International Caries Detection and Assessment System (ICDAS) in discriminating socioeconomic factors associated with the presence of caries lesions at both noncavitated and cavitated thresholds and to compare with the standard World Health Organization (WHO) criteria. The study was carried out in Amparo, Brazil, during the National Day of Children's Vaccination including 252 children aged 36-59 months. The same child was independently examined by two calibrated examiners, one using the ICDAS and the other using WHO criteria. Socioeconomic information was also recorded. Associations between socioeconomic factors and presence of caries assessed as binary (caries prevalence) and count outcome (actual dmfs values) obtained by WHO criteria and by ICDAS at noncavitated and cavitated thresholds were evaluated by Poisson regression analysis with robust variance. Some covariates were significantly associated with the presence of caries evaluated by the WHO criteria and by ICDAS (using score 3 as cut-off point). When noncavitated scores of ICDAS were used to calculate the presence of caries, the discriminant power decreased. When dmfs values were used as outcome, no differences in the associations were observed between two systems or using noncavitated caries lesions. Cavitated scores of ICDAS present similar discriminant validity compared with WHO criteria when presence of caries is used as outcome; however, when actual dmfs values are used, no differences are observed in using noncavitated or cavitated caries lesions. © 2010 John Wiley & Sons A/S.

    Full Text Available Abstract Background and purpose Patients with internal carotid artery (ICA occlusion can demonstrate impaired cerebral vascular reserve (CVR. The detection of CVR using single photon emission CT (SPECT is nowadays widely accepted as a predictor in the diagnostic pathway in patients considered for cerebral revascularization. Recently perfusion CT (PCT gained widely acceptance in stroke imaging The present study was aimed at comparing the results of perfusion CT (PCT and 99mTc-HMPAO SPECT with acetazolamide challenge in patients with ICA occlusion. Methods 13 patients were included in the prospective evaluation. Both PCT and 99mTc-HMPAO SPECT were performed before and after the administration of acetazolamide. In detail, regional cerebral blood flow (rCBF, regional cerebral blood volume (rCBV, adapted time to peak (Tmax and mean transit times (MTT were compared with SPECT data. Results 99mTc-HMPAO SPECT demonstrated an impairment of CVR in six patients. A preserved CVR was present in seven patients. All patients with impaired CVR proven by SPECT had a delayed MTT (mean +2.98 s and a delayed Tmax (mean + 5.9 s, (both p Conclusion The prospective study demonstrated a highly significant correlation of perfusion parameters as' detected by 99mTc-HMPAO SPECT and the Tmax as detected by PCT in patients with ICA occlusion. Therefore this easy-to-perform technique seems to be an adequate method for the evaluation of cerebral perfusion in patients with ICA occlusion.

    In this study, we aimed to compare the outcomes of satisfaction of the patients who used hearing aids preceding the vibrant sound bridge (VSB) application on middle ear windows (14 oval window and 5 round window). Nineteen adult patients with conductive or mixed hearing loss were included in the study. All patients used behind the ear hearing aids on the site which was selected for VSB application. The patients used hearing aids for at least 3 months before the VSB operation. The floating mass transducer (FMT) was placed on one of the middle ear windows (oval or round) in VSB operation. The patients were evaluated with International Outcome Inventory for Hearing Aids (IOI-HA) preoperatively after at least 3 months trial of conventional hearing aid and postoperatively after 3 months use of VSB. No perioperative problem was encountered. The total score of IOI-HA was significantly higher with VSB compared with conventional hearing aids (p 0.05). The IOI-HA scores were significantly higher with the middle ear implant than the conventional hearing aid regarding benefit and residual participation restrictions (p < 0.05). Although the scores for quality of life assessment was similar between VSB and hearing aid use, there was a superiority of VSB in terms of benefit and residual participation restrictions as well as overall IOI-HA scores as the FMT was placed on one of the middle ear windows.

    Medicare cost reports (MCR), Internal Revenue Service form 990s (IRS 990), and audited financial statements (AFS) vary in their content, detail, purpose, timeliness, and certification. The purpose of this study was to compare selected financial data elements and characterize the extent of differences in financial data and ratios across the MCR, IRS 990, and AFS for a sample of nonprofit critical access hospitals (CAHs). Line items from AFS of 47 CAHs were compared to data reported in the hospitals' MCR and IRS 990s. Line items were based on 9 financial indicators commonly used to assess hospital financial performance. Of the indicators examined, the equity financing ratio most frequently matched between the 3 reports, while salaries and benefits to total expenses and debt service coverage were often different. Variances were driven by differences in individual account balances used to construct the ratios. Relative to AFS, cash was frequently lower on the IRS 990 while marketable securities and unrestricted investments were often higher. Other revenue and net income were consistently lower on the MCR and IRS 990, and depreciation was often higher on the MCR. The majority of total assets and fund balance (equity) values matched across the 3 reports, suggesting differences in classification among detailed accounts were more common than variances between the component totals (total assets, total liabilities, and fund balance). Health policy researchers should consider the impact of these variances on study results and consider ways to improve the availability and quality of financial accounting information. © 2012 National Rural Health Association.

    There are relatively few studies in the literature that specifically evaluate accelerated rehabilitation protocols for distal radial fractures treated with open reduction and internal fixation (ORIF). The purpose of this study was to compare the early postoperative outcomes (at zero to twelve weeks postoperatively) of patients enrolled in an accelerated rehabilitation protocol with those of patients enrolled in a standard rehabilitation protocol following ORIF for a distal radial fracture. We hypothesized that patients with accelerated rehabilitation after volar ORIF for a distal radial fracture would have an earlier return to function compared with patients who followed a standard protocol. From November 2007 to November 2010, eighty-one patients with an unstable distal radial fracture were prospectively randomized to follow either an accelerated or a standard rehabilitation protocol after undergoing ORIF with a volar plate for a distal radial fracture. Both groups began with gentle active range of motion at three to five days postoperatively. At two weeks, the accelerated group initiated wrist/forearm passive range of motion and strengthening exercises, whereas the standard group initiated passive range of motion and strengthening at six weeks postoperatively. Patients were assessed at three to five days, two weeks, three weeks, four weeks, six weeks, eight weeks, twelve weeks, and six months postoperatively. Outcomes included Disabilities of the Arm, Shoulder and Hand (DASH) scores (primary outcome) and measurements of wrist flexion/extension, supination, pronation, grip strength, and palmar pinch. The patients in the accelerated group had better mobility, strength, and DASH scores at the early postoperative time points (zero to eight weeks postoperatively) compared with the patients in the standard rehabilitation group. The difference between the groups was both clinically relevant and statistically significant. Patients who follow an accelerated rehabilitation

    In this present days and age, there are increasing needs for companies to monitor application and infrastructure health. Apart from having proactive measures to secure their application and infrastructure, many see monitoring dashboards as crucial investment in disaster preparedness. As companies struggle to find the best solution to cater for their needs and interest for monitoring their application and infrastructure's health, this paper summarizes the studies made on several known off-the-shelf operations dashboard and in-house developed dashboard. A few criteria of good dashboard are collected from previous studies carried out by several researchers and rank them according to importance and business needs. The finalized criteria that will be discussed in later sections are data visualization, performance indicator, dashboard personalization, audit capability and alert/ notification. Comparative studies between several popular dashboards were then carried out to determine whether they met these criteria that we derived from the first exercise. The findings hopefully can be used to educate and provide an overview of selecting the best IT application and infrastructure operations dashboard that suit business needs, thus become the main contribution of this paper.

    Fabrication of plutonium containing fuels through the internal gelation method has mostly been studied in mixed metal systems such as U, Pu or Zr,Pu. In this work production of undiluted PuN has been performed by carbothermal reduction on both oxide powder and Pu microspheres produced by the internal gelation method. Nitride purities reached using the different methods have been studied together with final densities achieved during pellet fabrication as well as losses of ingrown Am during the different production steps. Formation of Pu microspheres was successfully performed using the internal gelation method, although extensive microsphere fracturing occurred during thermal treatment. Final densities of PuN pellets produced by cold pressing and sintering reached 70–80% of theoretical density. Am losses during the carbothermal reduction step was on average about 3.7%. After sintering about 11% of Am was lost in total through the entire production process if sintering in N{sub 2} + 5% H{sub 2} atmosphere while about 50% of the Am in total was lost when using Ar as sintering atmosphere. - Highlights: • Internal gelation Pu based sols was performed. • Nitride formation by carbothermal reduction on Pu microspheres and powders was performed. • Pelletization and sintering of pellets was performed. • Am losses were measured throughout the production steps.

  12. Eighth-grade science teachers use of instructional time: Examining questions from the Third International Mathematics and Science Study (TIMSS) and comparing TIMSS and National Science Foundation questionnaires

    Davidson, Anne Burgess

    Did the Third International Mathematics and Science Study (TIMSS) ask science teachers the right questions about their use of instructional time? Part I of this 2-part study used the TIMSS database to answer the question: Do 8th grade science teachers in the U.S., Czech Republic, Hungary, Japan, and Korea differ significantly in their perceived use of instructional time? Using the instructional activities in the TIMSS teacher question "How did the lesson proceed?" the teacher-reported times were analyzed using a repeated measures multivariate analysis. Significant differences were found between teacher-reported times in the U.S. and the other 4 TIMSS countries, whose 8th grade students outperformed U.S. students on TIMSS achievement tests. Post-hoc analysis indicated that TIMSS U.S. 8th grade science teachers report spending more time on homework in class, on group activities, and on lab activities, but less time on topic development, than TIMSS teachers from some or all of the other countries. Part II of this study further examined the question "How did the lesson proceed?" by videotaping 6 classes of 8th grade science in Alabama and Virginia and comparing observer coding of the video to the teachers' recalled descriptions of the same class. The difference between observer and teacher responses using TIMSS categories was not significant; however, 43% of the total variance was explained by whether the teacher or the observer reported the times for the instructional activities. The teachers also responded to questions from the NSF Local Systemic Change Through Teacher Enhancement K--8 Teacher Questionnaire to describe the same class. The difference found between the teacher and the observer coding was not significant, but the amount of variance explained by the data source (observer or teacher) dropped to 33% when using NSF student activity categories and to 26% when using NSF teacher activity categories. The conclusion of this study was that questionnaires to

    We investigated the efficiency droop and polarization-induced internal electric field of InGaN blue light-emitting diodes (LEDs) grown on silicon(111) and c-plane sapphire substrates. The efficiency droop of the LED sample grown on silicon substrates was considerably lower than that of the identically fabricated LED sample grown on sapphire substrates. Consequently, the LED on silicon showed higher efficiency at a sufficiently high injection current despite the lower peak efficiency caused by the poorer crystal quality. The reduced efficiency droop for the LED on silicon was attributed to its lower internal electric field, which was confirmed by reverse-bias electro-reflectance measurements and numerical simulations. The internal electric field of the multiple quantum wells (MQWs) on silicon was found to be reduced by more than 40% compared to that of the MQWs on sapphire, which resulted in a more homogenous carrier distribution in InGaN MQWs, lower Auger recombination rates, and consequently reduced efficiency droop for the LEDs grown on the silicon substrates. Owing to its greatly reduced efficiency droop, the InGaN blue LED on silicon substrates is expected to be a good cost effective solution for future lighting technology.

    A number of alternative process and waste form options exist for the immobilization of nuclear wastes. Although data exists on the characterization of these alternative waste forms, a straightforward comparison of product properties is difficult, due to the lack of standardized testing procedures. The characterization study described in this report involved the application of the same volatility, mechanical strength and leach tests to ten alternative waste forms, to assess product durability. Bulk property, phase analysis and microstructural examination of the simulated products, whose waste loading varied from 5% to 100% was also conducted. The specific waste forms investigated were as follows: Cold Pressed and Sintered PW-9 Calcine; Hot Pressed PW-9 Calcine; Hot Isostatic Pressed PW-9 Calcine; Cold Pressed and Sintered SPC-5B Supercalcine; Hot Isostatic pressed SPC-5B Supercalcine; Sintered PW-9 and 50% Glass Frit; Glass 76-68; Celsian Glass Ceramic; Type II Portland Cement and 10% PW-9 Calcine; and Type II Portland Cement and 10% SPC-5B Supercalcine. Bulk property data were used to calculate and compare the relative quantities of waste form volume produced at a spent fuel processing rate of 5 metric ton uranium/day. This quantity ranged from 3173 L/day (5280 Kg/day) for 10% SPC-5B supercalcine in cement to 83 L/day (294 Kg/day) for 100% calcine. Mechanical strength, volatility, and leach resistance tests provide data related to waste form durability. Glass, glass-ceramic and supercalcine ranked high in waste form durability where as the 100% PW-9 calcine ranked low. All other materials ranked between these two groupings

  1. Comparative Packaging Study

    Perchonok, Michele H.; Oziomek, Thomas V.

    2009-01-01

    Future long duration manned space flights beyond low earth orbit will require the food system to remain safe, acceptable and nutritious. Development of high barrier food packaging will enable this requirement by preventing the ingress and egress of gases and moisture. New high barrier food packaging materials have been identified through a trade study. Practical application of this packaging material within a shelf life test will allow for better determination of whether this material will allow the food system to meet given requirements after the package has undergone processing. The reason to conduct shelf life testing, using a variety of packaging materials, stems from the need to preserve food used for mission durations of several years. Chemical reactions that take place during longer durations may decrease food quality to a point where crew physical or psychological well-being is compromised. This can result in a reduction or loss of mission success. The rate of chemical reactions, including oxidative rancidity and staling, can be controlled by limiting the reactants, reducing the amount of energy available to drive the reaction, and minimizing the amount of water available. Water not only acts as a media for microbial growth, but also as a reactant and means by which two reactants may come into contact with each other. The objective of this study is to evaluate three packaging materials for potential use in long duration space exploration missions.

    We evaluated the concordance of results from two sets of nonclinical cardiovascular safety studies on pitolisant. Nonclinical studies envisaged both in the International Conference on Harmonization (ICH) S7B guideline and Comprehensive in vitro Pro-arrhythmia Assay (CiPA) initiative were undertaken. The CiPA initiative included in vitro ion channels, stem cell-derived human ventricular myocytes, and in silico modelling to simulate human ventricular electrophysiology. ICH S7B-recommended assays included in vitro hERG (K V 11.1) channels, in vivo dog studies with follow-up investigations in rabbit Purkinje fibres and the in vivo Carlsson rabbit pro-arrhythmia model. Both sets of nonclinical data consistently excluded pitolisant from having clinically relevant QT-liability or pro-arrhythmic potential. CiPA studies revealed pitolisant to have modest calcium channel blocking and late I Na reducing activities at high concentrations, which resulted in pitolisant reducing dofetilide-induced early after-depolarizations (EADs) in the ICH S7B studies. Studies in stem cell-derived human cardiomyocytes with dofetilide or E-4031 given alone and in combination with pitolisant confirmed these properties. In silico modelling confirmed that the ion channel effects measured are consistent with results from both the stem cell-derived cardiomyocytes and rabbit Purkinje fibres and categorized pitolisant as a drug with low torsadogenic potential. Results from the two sets of nonclinical studies correlated well with those from two clinical QT studies. Our findings support the CiPA initiative but suggest that sponsors should consider investigating drug effects on EADs and the use of pro-arrhythmia models when the results from CiPA studies are ambiguous. © 2017 The Authors.

    The concentration of Pb, Cd, Cu, Zu, Ni, Fe and Mn were determined in water, and in different organs of fishes, bivalves, snails and plants in Ismailia canal, Egypt. Moreover, accumulation of the investigated heavy metals by aquatic biota in Ismailia canal and the concentration factor values for this accumulation were calculated to qualify the degree of pollution and compare these levels with the international permissible limits. Results showed that Pb, Cd, Cu and Zn were exceeded the permissible limits especially in the industrial area of Abu- Zaabal, Kalubia governorate. The relative order of heavy metal levels in the canal water was: Fe>Mn>Pb>Zn>Ni>Cd>Cu.Accumulation of heavy metals by the aquatic biota was determined. The accumulation of heavy metals by common snails, namely physa acuta and biomphalaria alexandrina and the bivalve oyster Caelatura (caelatura) companyoi was found mainly in the edible parts (soft parts), whereas, the accumulation by their shells, which are mainly formed of calcium carbonate was via adsorption and surface complexation, since all the accumulated heavy metals were released by adding 0.1 M HCl for few minutes . Moreover, accumulation of heavy metals by common plants namely water hyacinth plant (Eichhornia crassipes) and freshwater weeds were determined. It was found that the accumulation of heavy metals was higher in roots than in leaves. On the other hand, the accumulation of heavy metals by common fish namely, Oreochromis niloticus (Nile Tilapia) was measured in its organs : muscles, liver, gills and gonads. It was found that there is variation of distribution of heavy metals among fish organs. Since the high accumulation of heavy metals among the investigated biota, they can be used as biological indicator for pollution of heavy metals in aquatic ecosystem . The average values and standard deviation for all measurements were determined. Data obtained were compared with the permissible concentrations of the environmental protection

    Full Text Available Introduction: A systematic approach is needed for effective coping an incident. In such a system, the preparedness is the top priority. The organization’s readiness depends on some factors, including regular exercises. To conduct a proper exercise it is necessary to have a comprehensive scenario. Despite of repetitive execution of exercises, there is no commonly accepted template for it. The present study aims at selecting preferred method for developing an emergency exercise. Methods: In the present study, ISO 22398 and HSEEP as the two common patterns were compared through quantifying their usability and chosen by AHP. A panel of crisis experts scored the usability criteria of methods and selected the preferred method. Results: The assessment of usability of both patterns revealed the preference of ISO pattern in comparison with the HSEEP pattern. The HSEEP method had the better score in learnability and satisfaction, but, the effectiveness, efficiency and total score were higher for ISO 22398. Conclusion: To develop an emergency scenario, it is necessary to follow a suitable pattern. The pattern presented by ISO 22398 is more usable in comparison with HSEEP paten.

    Full Text Available ABSTRACT OBJECTIVE: To evaluate, compare and identify the surgical technique with best results for treating intra-articular calcaneal fractures, taking into account postoperative outcomes, complications and scoring in the Aofas questionnaire. METHODS: This was a retrospective study on 54 patients with fractures of the calcaneus who underwent surgery between 2002 and 2012 by means of the following techniques: (1 open reduction with extended L-shaped lateral incision and fixation with double-H plate of 3.5 mm; (2 open reduction with minimal incision lateral approach and percutaneous fixation with wires and screws; and (3 open reduction with minimal incision lateral approach and fixation with adjustable monoplanar external fixator. RESULTS: Patients treated using a lateral approach, with fixation using a plate had a mean Aofas score of 76 points; those treated through a minimal incision lateral approach with screw and wire fixation had a mean score of 71 points; and those treated through a minimal incision lateral approach with an external fixator had a mean score of 75 points. The three surgical techniques were shown to be effective for treating intra-articular calcaneal fractures, without any evidence that any of the techniques being superior. CONCLUSION: Intra-articular calcaneal fractures are complex and their treatment should be individualized based on patient characteristics, type of fracture and the surgeon's experience with the surgical technique chosen.

    Full Text Available According to Horwitz (1987 learners’ belief about language learning are influenced by previous language learning experiences as well as cultural background. This study examined the English Language Learning Strategies between local and international Chinese students who share the same cultural background but have been exposed to different learning experiences. Given the significant number of local and international Chinese students enrolled in educational institutions, there is a need to understand the differences and similarities in the learning strategies of these two groups. The sample for the study comprised of 60 local and 50 international Chinese students currently enrolled at a local private college. The Oxford Strategy Inventory for Language Learning (SILL was administered as a measure of learning strategy preferences. The study reveals that language learning experiences as well as socioeconomic status impact the learning strategy adopted by both local and international Chinese students. The findings of this study point to the need to address the needs of these students in order to enhance their English language learning experience in Malaysia.

    This study investigated into the news frames employed in reporting on the Fukushima Daiichi nuclear accident, explored the maintenance of the radiation reporting standard, and assessed the overall tone for the local government, the Japanese Government, and the IAEA. Based on content from Der Spiegel, the Japan Times and the Los Angeles Times (n=60), it was found that media evoked 'conflict', 'responsibility attribution', and 'human interest' frames, radiation reporting standard was marginally maintained, and the overall tone was neutral (local government, IAEA) or negative (Japanese Government). Variances across countries were observed, but results coincided with the country's nuclear energy policy. (author)

  13. Comparative Education and Research Capacity Building: Reflections on International Transfer and the Significance of Context

    Directory of Open Access Journals (Sweden)

    Michael Crossley

    2012-04-01

    Full Text Available Recent years have seen a resurgence of interest in comparative and international education, along with a fundamental reconceptualisation of this distinctive multidisciplinary field of study. The nature and significance of these developments are explored with particular reference to their implications for broader research capacity building initiatives worldwide. In doing so, a critique of the international transfer of globally dominant research modalities and strategies is presented--along with arguments for increased attention to context sensitivity in both international development cooperation and educational research in general. Illustrative examples that support these arguments are drawn from the author's own research, from an analysis of emergent educational policy debates in the UK, and from related studies being carried out in Malaysia. In concluding, the strategic role of comparative research traditions and perspectives in a rapidly globalizing world is highlighted, while supporting the promotion of new initiative and research centres for comparative and international education.

  14. Internal dosimetry for epidemiologic studies

    International Nuclear Information System (INIS)

    Groer, P.G.

    1987-01-01

    In traditional epidemiologic analyses, a single valued summary index, the standardized mortality ratio (SMR), is quite popular. The SMR is simply the ratio of the number of deaths observed in the study population to the number of deaths expected if the study population were subject to the age-specific rates of a standard population. SMRs for all causes or specific causes can be calculated. For such a simple analysis an exposed cohort is often characterized by an average organ or whole body dose or dose interval, and the necessary dose estimation effort is relatively minor. Modern statistical methods focus on the estimation of the cause-specific mortality rate λ for study populations exposed to ionizing radiations or toxic chemicals. The dependence of λ on factors other than demographic characteristics, such as race and sex, is usually described through a parametric model. Such factors, often called covariates or covariables, are incorporated in the mathematical expression for the hazard rate. The external gamma dose or the internal lung dose from inhaled uranium are good examples for covariates. This type of analysis permits the use of individual doses and gives a detailed and quantitative description of the mortality rate as a function of the covariables, but at the cost of a major dosimetric effort. The generation of the necessary dose information and also the calculational efforts become especially taxing for time-dependent covariates such as an internal, cumulative organ dose. 4 refs

    Aromatase inhibitors provide superior disease control when compared with tamoxifen as adjuvant therapy for postmenopausal women with endocrine-responsive early breast cancer. To present the design, history, and analytic challenges of the Breast International Group (BIG) 1-98 trial: an international, multicenter, randomized, double-blind, phase-III study comparing the aromatase inhibitor letrozole with tamoxifen in this clinical setting. From 1998-2003, BIG 1-98 enrolled 8028 women to receive monotherapy with either tamoxifen or letrozole for 5 years, or sequential therapy of 2 years of one agent followed by 3 years of the other. Randomization to one of four treatment groups permitted two complementary analyses to be conducted several years apart. The first, reported in 2005, provided a head-to-head comparison of letrozole versus tamoxifen. Statistical power was increased by an enriched design, which included patients who were assigned sequential treatments until the time of the treatment switch. The second, reported in late 2008, used a conditional landmark approach to test the hypothesis that switching endocrine agents at approximately 2 years from randomization for patients who are disease-free is superior to continuing with the original agent. The 2005 analysis showed the superiority of letrozole compared with tamoxifen. The patients who were assigned tamoxifen alone were unblinded and offered the opportunity to switch to letrozole. Results from other trials increased the clinical relevance about whether or not to start treatment with letrozole or tamoxifen, and analysis plans were expanded to evaluate sequential versus single-agent strategies from randomization. Due to the unblinding of patients assigned tamoxifen alone, analysis of updated data will require ascertainment of the influence of selective crossover from tamoxifen to letrozole. BIG 1-98 is an example of an enriched design, involving complementary analyses addressing different questions several years

Further information on NOAA's regulations and NOAA's licensing program is available at www.licensing.noaa.gov. Monitoring and Enforcement NOAA's enforcement mission is focused on the legislative mandate which states that the Secretary of Commerce has a continuing obligation to ensure that licensed imaging systems are operated lawfully to preserve the national security and foreign policies of the United States. NOAA has constructed an end-to-end monitoring and compliance program to review the activities of licensed companies. This program includes a pre- launch review, an operational baseline audit, and an annual comprehensive national security audit. If at any time there is suspicion or concern that a system is being operated unlawfully, a no-notice inspection may be initiated. setbacks, three U.S. companies are now operational, with more firms expected to become so in the future. While NOAA does not disclose specific systems capabilities for proprietary reasons, its current licensing resolution thresholds for general commercial availability are as follows: 0.5 meter Ground Sample Distance (GSD) for panchromatic systems, 2 meter GSD for multi-spectral systems, 3 meter Impulse Response (IPR) for Synthetic Aperture Radar systems, and 20 meter GSD for hyperspectral systems (with certain 8-meter hyperspectral derived products also licensed for commercial distribution). These thresholds are subject to change based upon foreign availability and other considerations. It should also be noted that license applications are reviewed and granted on a case-by-case basis, pursuant to each system's technology and concept of operations. In 2001, NOAA, along with the Department of Commerce's International Trade Administration, commissioned a study by the RAND Corporation to assess the risks faced by the U.S. commercial remote

    Full Text Available In November 2010 the largest international study ever conducted on civic education in secondary schools has been released in Brussels. The study was performed under the auspices of the International Association for the Evaluation of Educational Achievement (IEA, an independent consortium that brings together educational researchers and policy makers in 62 countries around the world. The IEA is probably more widely known in connection of large-scale comparative studies on educational assessment in math and science (TIMSS and in reading (PIRLS. Yet, the association has longstanding and impressive expertise also in civic education. The first study in this area has been carried out already in 1971 (Torney et al., 1975, the second – so called CIVED in 1999 (Torney-Purta et al., 2001 and now, ten years later, 38 counties around the world participated in the third study – the IEA International Civic and Citizenship Education Study (ICCS. The study tested in 2008–2009 over 140,000 lower secondary students, over 62,000 teachers and headmasters from 5,300 schools in order to analyse how young people are prepared to undertake their roles as citizens.

    Suhag, Jyoti; Dureja, Harish

    2015-01-01

    The regulatory framework, compliance requirement, efficacy, safety, and marketing of cosmetic products are considered the most important factors for growth of the cosmetic industry. There are different regulatory bodies across the globe that have their own insights for regulation; moreover, governments such as the United States, European Union, and Japan follow a stringent regulatory framework, whereas cosmetics are not so much strictly regulated in countries such as India, Brazil, and China. The alignment of a regulatory framework will play a significant role in the removal of barriers to trade, growth of market at an international level, innovation in the development and presentation of new products, and most importantly safety and efficacy of the marketed products. The present contribution gives insight into the important cosmetic regulations in areas of premarket approval, ingredient control, and labeling and warnings, with a special focus on the cosmetic regulatory environments in the United States, European Union, Japan, and India. Most importantly, the authors highlight the dark side of cosmetics associated with allergic reactions and even skin cancer. The importance of cosmetic regulations has been highlighted by dint of which the society can be healthier, accomplished by more stringent and harmonized regulations.

  15. Compulsory licensing often did not produce lower prices for antiretrovirals compared to international procurement.

    Science.gov (United States)

    Beall, Reed F; Kuhn, Randall; Attaran, Amir

    2015-03-01

    Compulsory licensing has been widely suggested as a legal mechanism for bypassing patents to introduce lower-cost generic antiretrovirals for HIV/AIDS in developing countries. Previous studies found that compulsory licensing can reduce procurement prices for drugs, but it is unknown how the resulting prices compare to procurements through the Global Fund to Fight AIDS, Tuberculosis, and Malaria; UNICEF; and other international channels. For this study we systematically constructed a case-study database of compulsory licensing activity for antiretrovirals and compared compulsory license prices to those in the World Health Organization's (WHO's) Global Price Reporting Mechanism and the Global Fund's Price and Quality Reporting Tool. Thirty compulsory license cases were analyzed with 673 comparable procurements from WHO and Global Fund data. Compulsory license prices exceeded the median international procurement prices in nineteen of the thirty case studies, often with a price gap of more than 25 percent. Compulsory licensing often delivered suboptimal value when compared to the alternative of international procurement, especially when used by low-income countries to manufacture medicines locally. There is an ongoing need for multilateral and charitable actors to work collectively with governments and medicine suppliers on policy options.

  16. COMPARATIVE STUDY ON CORPORATE GOVERNANCE

    Directory of Open Access Journals (Sweden)

    Gavrea Corina

    2011-12-01

    Full Text Available Corporate governance is a key element of today’s economic reality being more and more present in many countries around the world. This paper has two main objectives. The first one is to offer more insight into the concept of corporate governance by a thorough literature review and by presenting and analyzing a framework of corporate governance. The second objective of this paper is to investigate the corporate governance situation in three developing economies (Romania, Bulgaria and Hungary. The World Bank and the European Bank for Reconstruction and Development published a series of reports on corporate governance. The present study uses data from these reports in order to illustrate how these developing economies are dealing with corporate governance. Based on ROSC Reports a corporate governance score was calculated. As this score shows, there is room for improvement for all three developing economies. This study is important because it shows the differences in corporate governance among developing economies and the need to study these nations at the individual country level. Corporate governance has many benefits for developing economies. It helps developing economies to register sustainable growth rates, to increases investors’ confidence in the national economy, and to increase the ability of capital markets to mobilize savings.

    The oil industry is dynamic and global, being performed worldwide and by investors from several countries. In this sense, it is essential for investors to be informed of the legal frameworks in target countries and the differences between the legislation in those countries and their own legal systems. In this article, we will analyze the main differences on the environmental liability in Brazil, which is, currently, one of the most attractive markets in the oil and gas industry, the United States of America (US), the largest consumer of oil and the third producer around the world; and the European Union (EU) which concentrates the second largest global consumer, besides being the main player in the international and diplomatic relationships. Thus, the present paper, without the intent to exhaust the subject matter, aims at presenting comparisons between the legal environment of the three main players in the international oil and gas scenario, specifying not only the legal aspects of each of them, but also outlining the economic impacts generated over business investors from the oil industry, determining that although the differences in the basis of legal framework, all players have presented the liability and the duty to compensate.

    Objective: Complicated aneurysms located in the cisternal segment of the internal carotid artery(ICA-CSA) present unique therapeutic difficulties. This study is to discuss the feasibility of the Willis stent-graft in treating complicated ICA-CSA by comparing its effect with that of coiling therapy. Methods: Willis covered stents were employed in 19 complicated ICA-CSAs (group A), while coils were used in 17 complicated ICA-CSAs (group B). Follow-up angiography was performed to investigate aneurysm recurrence, endoleak and parent artery (PA) stenosis. Kaplan-Meier curves were constructed to compare the recurrence-free and PA stenosis-free rate in both groups. Results: Total exclusion was immediately achieved in 13 ICA-CSAs and minor endoleaks presented in 5 cases in group A. Total or near-total occlusion was achieved in 7 ICA-CSAs, subtotal occlusion in 8 and partial occlusion in 2 cases in group B after coiling. Acute thrombosis occurred in 1 patient in either group and re-hemorrhage happened in 1 patient after coiling. Follow-up angiography in group A revealed that 16 ICA-CSAs were completely isolated, with two parent arteries showing mild in-stent stenosis. Eighteen months after the procedure, Kaplan-Meier analysis showed that the recurrence-free rate was 93.3% and 50%, while the stenosis-free rate of parent artery was 87.5% and 100% in group A and in Group B, respectively. In group A and group Bthe clinical neurological symptoms were fully recovered in 9 and 9, obviously improved in 3 and 5, unchanged in 2 and 2, and aggravated in one and 0 patients, respectively. Conclusion: The implantation of Willis stent-graft is a feasible endovascular therapy for complicated ICA-CSAs. When the parent artery is very tortuous or when the risk that a main collateral branch may be wrongly covered and occluded is present, the implantation of Willis covered stent can not be taken as the treatment of first choice.

    2015-05-01

    Full Text Available Background: Age patterns are a key dimension to compare migration between countries and over time. Comparative metrics can be reliably computed only if data capture the underlying age distribution of migration. Model schedules, the prevailing smoothing method, fit a composite exponential function, but are sensitive to function selection and initial parameter setting. Although non-parametric alternatives exist, their performance is yet to be established. Objective: We compare cubic splines and kernel regressions against model schedules by assessingwhich method provides an accurate representation of the age profile and best performs on metrics for comparing aggregate age patterns. Methods: We use full population microdata for Chile to perform 1,000 Monte-Carlo simulations for nine sample sizes and two spatial scales. We use residual and graphic analysis to assess model performance on the age and intensity at which migration peaks and the evolution of migration age patterns. Results: Model schedules generate a better fit when (1 the expected distribution of the age profile is known a priori, (2 the pre-determined shape of the model schedule adequately describes the true age distribution, and (3 the component curves and initial parameter values can be correctly set. When any of these conditions is not met, kernel regressions and cubic splines offer more reliable alternatives. Conclusions: Smoothing models should be selected according to research aims, age profile characteristics, and sample size. Kernel regressions and cubic splines enable a precise representation of aggregate migration age profiles for most sample sizes, without requiring parameter setting or imposing a pre-determined distribution, and therefore facilitate objective comparison.

    2013-01-01

    Fuel cells generate electricity and heat during electrochemical reaction which happens between the oxygen and hydrogen to form the water. Fuel cell technology is a promising way to provide energy for rural areas where there is no access to the public grid or where there is a huge cost of wiring and transferring electricity. In addition, applications with essential secure electrical energy requirement such as uninterruptible power supplies (UPS), power generation stations and distributed systems can employ fuel cells as their source of energy. The current paper includes a comparative study of basic design, working principle, applications, advantages and disadvantages of various technologies available for fuel cells. In addition, techno-economic features of hydrogen fuel cell vehicles (FCV) and internal combustion engine vehicles (ICEV) are compared. The results indicate that fuel cell systems have simple design, high reliability, noiseless operation, high efficiency and less environmental impact. The aim of this paper is to serve as a convenient reference for fuel cell power generation reviews. (Author)

    The field of international education, in the sense of education experienced by growing numbers of children of parents who are internationally mobile and who wish their children to accompany them as they travel the world, has expanded rapidly since the 1940s. Increasing numbers of "international schools" offer "international education", which includes in some cases offering "international curricula", but little research has been undertaken to date into the precise nature of such education or the shared characteristics of such schools. This paper describes a small-scale study undertaken with undergraduate students at the University of Bath who had experienced such an education before registering at the University, and investigates the perceptions of these students with respect to a number of key issues identified as relevant to the field of international education.

    Full Text Available The well known events which had taken place in our country over the period 1989-2001 provoked adverse effects on foreign trade exchange of the total economy, agriculture and commodities of plant origin. These effects and changes were analyzed using corresponding indices for the sub periods 1989-1992 and 1998-2001. The foreign trade exchange balance was substantially negative in both sub periods over the analyzed period showing an aggravating trend. Export covering import declined from 78.09% to only 47.71%. The positive balance of exchange of agricultural, especially commodities of plant origin in the first four years was turned into a negative balance of exchange in the second four years. Export covering import at the agricultural level declined from 164.79% to 78.58% and at the level of commodities of plant origin from 201,76% to 87.35%. There was a significant disturbance of commodity and regional structure exchange. The share of agriculture in the total export of the country was raised from 13.82% to 18.16%. The share of plant originating commodities in the total export of agriculture was raised from 71,96% to 86,34%. Basic agricultural products predominated in the export. In addition, in the domestic export the share of developed countries decreased which contributed to poor export results and increased the import dependence of the country. Considering the above said, the need arises to increase substantially agricultural production, i.e. commodities of plant origin. The structure and output of these productions should meet the needs of both domestic and foreign markets. International standards need to be applied in order to take hold of new foreign markets, exporting high technology processed products, using intensive and efficient promotive activities. Subsequently, greater investments and a planned production are needed, liberalization and especially the system of import control in foreign trade exchange of agricultural products, i

    We review census data to assess the standing of five Latin American nations on a gender continuum ranging from patriarchal to matrifocal. We show that Mexico and Costa Rica lie close to one another with a highly patriarchal system of gender relations whereas Nicaragua and the Dominican Republic are similar in having a matrifocal system. Puerto Rico occupies a middle position, blending characteristics of both systems. These differences yield different patterns of female relative to male migration. Female householders in the two patriarchal settings displayed low rates of out-migration compared with males, whereas in the two matrifocal countries the ratio of female to male migration was much higher, in some case exceeding their male counterparts. Multivariate analyses showed that in patriarchal societies, a formal or informal union with a male dramatically lowers the odds of female out-migration, whereas in matrifocal societies marriage and cohabitation have no real effect. The most important determinants of female migration from patriarchal settings are the migrant status of the husband or partner, having relatives in the United States, and the possession of legal documents. In matrifocal settings, however, female migration is less related to the possession of documents, partner's migrant status, or having relatives in the United States and more strongly related to the woman's own migratory experience. Whereas the process of cumulative causation appears to be driven largely by men in patriarchal societies, it is women who dominate the process in matrifocal settings.

    The focus of the ISG work was on advancing the accelerator design and supporting technologies. This is a complex process which involves a close interaction between theoretical analysis of the collider design and R and D progress on hardware components. The sequence of efforts took place roughly in the following order: (1) Optimization of the collider parameters and definition of system and subsystem requirements, (2) Identification of design strategies and options, and (3) Development of specific technologies to achieve these requirements. Development and testing of the required components, and R and D on manufacturing techniques have been important activities of the ISG. Experiments at the major test facilities such as the ATF at KEK and ASSET at SLAC have also played a significant role in the ISG studies.

    Few studies have addressed the challenges associated with international students as they adapt to studying medicine in a new host country. Higher level institutions have increasing numbers of international students commencing programmes. This paper explores the experiences of a cohort of students in the early years of medical school in Ireland, where a considerable cohort are from an international background. A mixed exploratory sequential study design was carried out with medical students in the preclinical component of a five year undergraduate programme. Data for the qualitative phase was collected through 29 semi-structured interviews using the peer interview method. Thematic analysis from this phase was incorporated to develop an online questionnaire combined with components of the Student Adaptation to College Questionnaire and Student Integration Questionnaire. First year students were anonymously surveyed online. The Mokken Scaling procedure was used to investigate the students' experiences, both positive and negative. Three main themes are identified; social adjustment, social alienation and cultural alienation. The response rate for the survey was 49% (467 Respondents). The Mokken Scaling method identified the following scales (i) Positive experience of student life; (ii) Social alienation, which comprised of negative items about feeling lonely, not fitting in, being homesick and (iii) Cultural alienation, which included the items of being uncomfortable around cultural norms of dress and contact between the sexes. With the threshold set to H = 0.4. Subscales of the positive experiences of student life scale are explored further. Overall student adjustment to a western third level college was good. Students from regions where cultural distance is greatest reported more difficulties in adjusting. Students from these regions also demonstrate very good adaptation. Some students from the host country and more similar cultural backgrounds were also

    Across the globe, public acceptance of nuclear power is a crucial factor for governmental establishment of a nuclear energy program. Therefore, it is important to understand the determinants of public acceptance of nuclear power. This study examines the effects of knowledge, trust, risk, and benefit related factors on public acceptance of nuclear power across 19 countries. We consider three levels of public acceptance – strongly accept, reluctantly accept, and oppose – and classify countries into four groups according to the ratio of those three levels of public acceptance. Our results indicate that knowledge of nuclear inspection is more effective than trust in inspection authorities in creating stronger public acceptance among people in the countries with a high level of reluctant acceptance and a low level of strong acceptance, while trust in inspection authorities is more important than knowledge of nuclear inspection for the selection between opposition and reluctant acceptance in countries with a low level of reluctant acceptance and a high level of strong acceptance. Without grouping the countries, we found that trust in inspection authorities is crucial for the decision between opposition and reluctant acceptance. Additionally, the generation of electricity has the most positive effect on public acceptance of nuclear power. - Highlights: • We examine public acceptance (PA) of nuclear power across 19 countries. • Three levels of PA – strongly accept, reluctantly accept, and oppose – are considered. • Knowledge is most effective in creating stronger PA. • Trust is effective in shifting PA from opposition to reluctant acceptance. • Low risk and benefit of electricity generation enhance PA the most

  16. COMPARATIVE STUDY ON ACCOUNTING AND FISCAL AMORTIZATION

    2012-05-01

    Full Text Available Placed in the international trend, Romanian accounting had experienced various changes, especially as regards of progress on disconnection between accounting and fiscality. In the present, fiscal rules should not have any role in accounting decisions, because accounting rules are applied to produce accounting information that is useful in making decisions and to provide a "true and fair view" upon financial reality of the entity. However, the barrier in the habit of accounting to thinking for fiscal point of view all economic transactions remains insurmountable, yet. Starting from this perspective on disconnection between accounting and fiscality would mean that amortization recorded in the accounting, as a result of management policy, to be different from fiscality amortization, to calculate income tax. Although formally accepted, disconnect between accounting and fiscality continues to meet many difficulties. In this sense, it is usual in practice to use the same method of amortization for accounting purposes and for fiscal purposes to prevent complications of double track amortization and prevent wandering in the rules in this field. Accounting rule is deliberately eluded in favor of the fiscal rules. This is the reason we proposed to make in this paper a comparative study between norms and rules on accounting and fiscal amortization, paper in which we intend to show the benefits of applying accounting and fiscal rules separately.

  17. Comparative internal anatomy of Staurozoa (Cnidaria, with functional and evolutionary inferences

    Directory of Open Access Journals (Sweden)

    Lucília S. Miranda

    2016-10-01

    Full Text Available Comparative efforts to understand the body plan evolution of stalked jellyfishes are scarce. Most characters, and particularly internal anatomy, have neither been explored for the class Staurozoa, nor broadly applied in its taxonomy and classification. Recently, a molecular phylogenetic hypothesis was derived for Staurozoa, allowing for the first broad histological comparative study of staurozoan taxa. This study uses comparative histology to describe the body plans of nine staurozoan species, inferring functional and evolutionary aspects of internal morphology based on the current phylogeny of Staurozoa. We document rarely-studied structures, such as ostia between radial pockets, intertentacular lobules, gametoducts, pad-like adhesive structures, and white spots of nematocysts (the last four newly proposed putative synapomorphies for Staurozoa. Two different regions of nematogenesis are documented. This work falsifies the view that the peduncle region of stauromedusae only retains polypoid characters; metamorphosis from stauropolyp to stauromedusa occurs both at the apical region (calyx and basal region (peduncle. Intertentacular lobules, observed previously in only a small number of species, are shown to be widespread. Similarly, gametoducts were documented in all analyzed genera, both in males and females, thereby elucidating gamete release. Finally, ostia connecting adjacent gastric radial pockets appear to be universal for Staurozoa. Detailed histological studies of medusozoan polyps and medusae are necessary to further understand the relationships between staurozoan features and those of other medusozoan cnidarians.

    2017-01-01

    Full Text Available Objectives: Performance indicators are a popular mechanism for measuring the quality of healthcare to facilitate both quality improvement and systems management. Few studies make comparative assessments of different countries’ performance indicator frameworks. This study identifies and compares frameworks and performance indicators used in selected Organisation for Economic Co-operation and Development health systems to measure and report on the performance of healthcare organisations and local health systems. Countries involved are Australia, Canada, Denmark, England, the Netherlands, New Zealand, Scotland and the United States. Methods: Identification of comparable international indicators and analyses of their characteristics and of their broader national frameworks and contexts were undertaken. Two dimensions of indicators – that they are nationally consistent (used across the country rather than just regionally and locally relevant (measured and reported publicly at a local level, for example, a health service – were deemed important. Results: The most commonly used domains in performance frameworks were safety, effectiveness and access. The search found 401 indicators that fulfilled the ‘nationally consistent and locally relevant’ criteria. Of these, 45 indicators are reported in more than one country. Cardiovascular, surgery and mental health were the most frequently reported disease groups. Conclusion: These comparative data inform researchers and policymakers internationally when designing health performance frameworks and indicator sets.

    Full Text Available The complex networks approach has proven to be an effective tool to understand and predict the evolution of a wide range of complex systems. In this work, we consider the network representing the exchange of goods between countries: the international trade network. According to the type of goods they export, the complex networks approach allows inferring which countries will have a bigger growth compared to others. The aim of this work is to study three different methods characterizing the complex networks and study their behaviour on two main topics. Can the method predict the economic evolution of a country? What happens to those methods when we merge the economies?

    2013-11-01

    Full Text Available There is limited theoretical understanding and empirical evidence for how international new ventures legitimate. Drawing from legitimation theory, this study fills in this gap by exploring how international new ventures legitimate and strive for survival in the face of critical events during the process of their emergence. It is a longitudinal, multiple-case study research that employs critical incident technique for data collection, analysis, and interpretation. Following theory driven sampling, five international new ventures were selected that were operating in the software sector in the UK, and had internationalized and struggled for survival during the dotcom era. Grounded in data, this study corroborates a number of legitimation strategies yielded by prior research and refutes others. It further contributes to our understanding of international new venture legitimation by suggesting new types of legitimation strategies: technology, operating, and anchoring. Studying international new ventures through theoretical lenses of legitimation is a promising area of research that would contribute to the advancement of international entrepreneurship theory.

  4. Comparative analysis of fiscal terms for Alberta oil sands and international heavy and conventional oils

    International Nuclear Information System (INIS)

    Van Meurs, P.

    2007-01-01

    There are considerable differences between international heavy oil and Alberta oil sands projects, notably the high viscosity of the bitumen in the oil sands reservoirs. The oil sands bitumen do not flow to wells without heating the bitumen, thereby adding to the already high cost of Alberta oil sand operations. This report provided an economic comparison of Alberta oil sands and international heavy oil projects. It also included a brief scoping review to compare with conventional oil regimes. Full exploration costs including the costs of dry holes were allocated to conventional oil operations in order to obtain a proper comparison. This investigation included the costs of dry holes. The report was a follow up to an earlier study released on April 12, 2007 on the preliminary fiscal evaluation of Alberta oil sand terms. The report provided an economic framework and described project selection. It then provided a discussion of production, costs and price data. Four adjusted projects were presented and compared with Alberta. The Venezuelan royalty formula was also discussed. Last, the report provided a detailed fiscal analysis. Comparisons were offered with Cold Lake and Athabasca Mine. A review of some other fiscal systems applicable to conventional oil were also outlined. It was concluded that Alberta oil sands developments are very competitive. It would be possible to modestly increase government revenues, without affecting the international competitive position of Alberta with respect to conventional oil. There is also some possibility to increase the base royalty on the Alberta oil sands without losing competitiveness. tabs., figs

    Internalized stigma is the adoption of negative attitudes and stereotypes of the society regarding a person's illness. It causes decreased self-esteem and life-satisfaction, increased depression and suicidality, and difficulty in coping with the illness. The primary aim of this study was to investigate the internalized stigma state of psoriatic patients and to identify the factors influencing internalized stigma. The secondary aim was to identify the correlation of internalized stigma with quality of life and perceived health status. This multicentre, cross-sectional study comprised 1485 patients. There was a significant positive correlation between mean values of Psoriasis Internalized Stigma Scale (PISS) and Psoriasis Area and Severity Index, Body Surface Area, Dermatological Life Quality Index and General Health Questionnaire-12 (P percieved health score (P = 0.001), early onset psoriasis (P = 0.016), family history of psoriasis (P = 0.0034), being illiterate (P < 0.001) and lower income level (P < 0.001) were determinants of high PISS scores. Mean PISS values were higher in erythrodermic and generalized pustular psoriasis. Involvement of scalp, face, hand, genitalia and finger nails as well as arthropathic and inverse psoriasis were also related to significantly higher PISS scores (P = 0.001). Our findings imply that psoriatic patients experience high levels of internalized stigma which are associated with psoriasis severity, involvement of visible body parts, genital area, folds or joints, poorer quality of life, negative perceptions of general health and psychological illnesses. Therefore, internalized stigma may be one of the major factors responsible from psychosocial burden of the disease. © 2017 Japanese Dermatological Association.

Yet a kind of systematic structure that provides the basic principles for a coherent exposition of the field remains open. “Comparative education” is no longer conceived as an imaginary field’s coherence but, rather in terms of distinct branches of comparative and international studies in education and their underlying issues. Such an understanding is fostered through a dee...

    Science.gov (United States)

    Wilson, David N.

    2003-03-01

    This article examines the history and future prospects of comparative and international education with particular reference to the impact of globalisation and Information and Communications Technologies (ICTs). Connections and interactions between comparative educationists and the technologies of printing and electronic communications are examined in a historical context. The global nature of communications in comparative and international education is demonstrated both spatially and historically, using information from all regions of the world. The changing nature of technologies is noted to have broadened the audience for comparative insights. The development of textbooks, journals, conferences, international agencies, the Internet, web-based communications, and professional comparative education societies is related to the themes of communications and globalisation.

    2014-01-01

    The objective of this study is to perform a comparative analysis between the Brazilian legislation and internationals protocols, with respect to the quality control tests for computerized tomography. We used 07 references, published from 1998-2012: the Protocolo Brasileiro - Portaria 453/98 SVS/MS and the Guia de Radiodiagnostico Medico da ANVISA; Quality Assurance Programme for Computed Tomography: Diagnostic and Therapy Applications of the IAEA; European Protocol - European Guidelines on Quality Criteria for Computed Tomography of the EUR No. 16262 EN; Radiation Protection No. 162 - Criteria for Acceptability of Medical Radiology, Nuclear Medicine and Radiotherapy of the European Commission; the Protocols of Control de Calidad en Radiodiagnostico IAEA / ARCAL XLIX; and the Protocolo Espanol de Control de Calidad en Radiodignostico. The comparative analysis of these legislations was based on aspects of tolerance / limit, frequency and objectives of the recommended tests. Were found 18 tests in the Brazilian legislation. The tests were grouped according to their nature (dosimetric tests / exposure and geometric tests and image quality tests). Among the evaluated protocols was identified divergence between tests contained in the documents and the criteria of assessment set out in this work. It is clear, moreover, that for certain documents are not observed tolerances, well-defined methodologies and even frequency of testing. We conclude that the current legislation in Brazil differs in certain respects from international protocols analyzed, although this has a great numbers of quality control tests. However, it is necessary that the Brazilian legislation takes into account technological advances presented to time

    Carbon dioxide embodied flow in international trade has become an important factor in defining global carbon emission responsibility and climate policy. We conducted an empirical analysis for China and Japan for the years 2000-2014, using a multi-region input-output model and considering the rest of the world as a comparison group. We compared the two countries' direct and complete carbon dioxide emissions intensity and bilateral economic activities such as imports and exports, production and consumption to analyze the difference between China and Japan. The results showed that the intensities of carbon emissions in all sectors of China were higher than that in Japan and that China's annual production-based emissions were greater than consumption-based emissions, the opposite of these relationships in Japan. China was a typical net carbon export country, and carbon embodied in its imports and exports continued to increase throughout the study period. In contrast, Japan's volume and growth rate of embodied carbon emissions were far less than China's and Japan was a typical net carbon import country. Finally, the conclusions of this study support recommendations for the formulation of international carbon emission responsibility allocation, domestic abatement policy as well as China's trade policy.

  11. Comparing the Simplified and International Autoimmune Hepatitis Group Criteria in Primary Sclerosing Cholangitis

    Science.gov (United States)

    Chandok, Natasha; Silveira, Marina G.

    2010-01-01

    Background and aims: Although highly sensitive and specific, the revised International Autoimmune Hepatitis Group (IAIHG) diagnostic criteria for autoimmune hepatitis (AIH) are cumbersome to use in clinical practice and rely upon a number of autoantibodies that are costly and are not widely available. The simplified scoring system for AIH attempts to rectify the complexity of the IAIHG criteria. To date, there have been few studies assessing the specificity of the simplified score for AIH when applied to patients with cholestatic liver diseases. The purpose of this study was to examine the specificity of the simplified scoring system for AIH as compared to the revised IAIHG criteria in a large cohort of patients with primary sclerosing cholangitis (PSC). Methods: The patient population consisted of 147 patients enrolled in two prospective trials at the Mayo Clinic examining the use of ursodeoxycholic acid in PSC. All of the patients underwent baseline blood work (including standard serologic testing to exclude other liver diseases), liver biopsy, and cholangiogram to confirm PSC. Demographic, laboratory, and histologic data were extracted for each subject. Simplified and revised IAIHG scores were calculated for each subject and compared. Results: The simplified scoring system identified 2 patients with probable AIH and no patients with definite AIH. Comparatively, the revised IAIHG scoring system identified no patients with probable or definite AIH. Conclusion: As with the revised IAIHG criteria, the simplified scoring system for AIH has excellent specificity when applied to a PSC population. PMID:20567552

    Interleukin-6 (IL-6) may play an important role in the pathophysiology of anemia of inflammation associated with myelodysplastic syndrome (MDS). This double-blind, placebo-controlled, phase 2 study assessed the efficacy and safety of siltuximab, a chimeric anti-IL-6 monoclonal antibody, in patients with low- and intermediate-1-risk MDS who require transfusions for MDS anemia. Patients were randomized in a 2:1 ratio to siltuximab 15 mg kg(-1) every 4 weeks + best supportive care (BSC) or placebo + BSC for 12 weeks. The primary endpoint was reduction in red blood cell (RBC) transfusions to treat MDS anemia, defined as ≥50% relative decrease and ≥2-unit absolute decrease in RBC transfusions. Fifty and 26 patients were randomized to the siltuximab and placebo groups, respectively. The study did not meet its prespecified hypothesis, with six (12%) patients in the siltuximab group and one (3.8%) in the placebo group having reductions in RBC transfusions (P = 0.271). At the time of the planned futility analysis, the prespecified cutoff criteria were not met, and the study was terminated early due to lack of efficacy. No unexpected safety findings were observed. In conclusion, compared to placebo, treatment with siltuximab did not reduce RBC transfusions in transfusion-dependent patients with low- and intermediate-1-risk MDS. Future studies might explore siltuximab in patients with less iron overload and with elevated IL-6 levels and/or using higher doses for MDS. © 2014 Wiley Periodicals, Inc.

  16. INTERNAL GOVERNANCE AND ROLE OF INTERNAL AUDIT IN FINANCIAL INSTITUTIONS. CASE STUDY: RISK BASED PLANNING

    Directory of Open Access Journals (Sweden)

    Andrei Florin

    2015-07-01

    Full Text Available The global financial crisis from 2008 was considered a trigger to reshape the financial systems and to enhance the risk management practices. Considering the developments and new guidelines that are now used it can be observed a “positive” effect of the crisis, in particular to strengthen the risk management culture and governance in all aspects. Comparing to 2008 year, the improvements that have been made to the risk management systems can be easily observed in the financial institutions. For the scope of the article, the subject of this review will be focused on the internal audit function. The main aspect is to capture the new practices that are now used in order to contribute to a performing internal governance system. A case study will be presented in order to better understand how the internal audit function is designed and acting as a “line” of defence in the internal governance system. Also, it is in the scope of the article to issue some recommendations for future developments of the audit function in order to better manage its mission and the objectives. A risk based model used in the planning activities is presented. The financial institutions improved significantly their internal governance system. The internal audit function is now better integrated in the internal structures and clear lines of communication were settled. As the conclusion of the article is illustrating, the internal governance was frequently not sufficiently developed causing a failure in the risk management systems from the systemically financial institutions. The content of the article has practical applicability, as the results and the recommendations could be used in the design of an audit function within a financial institution.

    2016-01-01

    Internalized weight stigma has gained growing interest due to its association with multiple health impairments in individuals with obesity. Especially high internalized weight stigma is reported by individuals undergoing bariatric surgery. For assessing this concept, two different self-report questionnaires are available, but have never been compared: the Weight Self-Stigma Questionnaire (WSSQ) and the Weight Bias Internalization Scale (WBIS). The purpose of the present study was to provide and to compare reliability, convergent validity with and predictive values for psychosocial health outcomes for the WSSQ and WBIS. The WSSQ and the WBIS were used to assess internalized weight stigma in N = 78 prebariatric surgery patients. Further, body mass index (BMI) was assessed and body image, quality of life, self-esteem, depression, and anxiety were measured by well-established self-report questionnaires. Reliability, correlation, and regression analyses were conducted. Internal consistency of the WSSQ was acceptable, while good internal consistency was found for the WBIS. Both measures were significantly correlated with each other and body image. While only the WSSQ was correlated with overweight preoccupation, only the WBIS was correlated with appearance evaluation. Both measures were not associated with BMI. However, correlation coefficients did not differ between the WSSQ and the WBIS for all associations with validity measures. Further, both measures significantly predicted quality of life, self-esteem, depression, and anxiety, while the WBIS explained significantly more variance than the WSSQ total score for self-esteem. Findings indicate the WSSQ and the WBIS to be reliable and valid assessments of internalized weight stigma in prebariatric surgery patients, although the WBIS showed marginally more favorable results than the WSSQ. For both measures, longitudinal studies on stability and predictive validity are warranted, for example, for weight-related and

    Social inclusion of people with mental health issues is an aim of the World Health Organisation. Many countries have adopted that objective, including Brazil and the United Kingdom and both have focused treatment in the community. The aim of this article is to compare international results using the same inclusion instrument. The samples in this study were 225 people with mental health issues in community services in São Paulo, Brazil. Their results are compared to findings from 168 people with similar mental health issues in Hong Kong, China, and from the United Kingdom - a nationally representative sample of 212 people without mental health issues. The instrument used to measure a social inclusion called Social and Communities Opportunities Profile (SCOPE) has been validated for use in the United Kingdom, China and Brazil. The results are that people with mental health issues have worse social inclusion when compared to general population. Between the people with mental health issues, the sample of São Paulo has the lowest social inclusion index but, in relation to access to the Brazilian revised mental health services, that sample has a similarly high inclusion rating to the general population of the United Kingdom. Findings are important to understand mental health in the community context, as well as their adversities and potentialities.

    2013-12-01

    According to the guidelines of the European Society of Cardiology, a presumed diagnosis of neurally mediated syncope (NMS) can be made when patients have a consistent history and competing diagnoses are excluded. In the present study, we compared the initial diagnosis of NMS by means of implantable loop recorder (ILR) documentation. In this prospective multicentre observational study which involved 51 hospitals in nine countries in Europe and Canada, 504 NMS patients ≥40 years, who had suffered ≥3 syncopal episodes in the previous 2 years received an ILR and were followed up for a mean of 15±11 months. ILR recorded a spontaneous syncope in 187 cases, with an estimated diagnostic yield of 47% at 3 years. ILR findings were consistent with the initial diagnosis of presumed NMS in 162 (87%) patients whereas did not confirm NMS in another 25 (13%), who had an intrinsic cardiac arrhythmic cause (atrial tachyarrhythmias (#6), long pause on termination of tachyarrhythmia (#8), persistent bradycardia (#3), ventricular tachycardia (#4)) or a non-arrhythmic loss of consciousness (non-syncopal (#3), orthostatic hypotension (#1)). No clinical baseline feature was able to predict an intrinsic cardiac cause with the exception of more frequent non-syncopal atrial tachyarrhythmias on clinical history, which were present in 38% of cardiac versus 5% of NMS patients (p=0.001). Tilt table testing (TT) was positive in 76/136 (56%) presumed NMS and in 9/21 (43%) non-NMS patients (p=0.35); an asystolic response was present in 28/136 (21%) NMS and in 0/21 (0%) non-NMS patients (p=0.03). ILR findings showed results other than NMS in a small, although non-negligible, number of patients older than 40 years. TT was unable to discriminate between presumed NMS and non-NMS with the exception of an asystolic response which was highly specific.

    2008-12-01

    Full Text Available The aim of the International Study on the Impact of Copyright Law on Digital Preservation was to review current copyright and related laws and their impact on digital preservation, as well as to make recommendations to help libraries, archives and other preservation institutions sustain digital works. Study partners are based in Australia, the Netherlands, the United Kingdom and the United States. The study found that, in many cases, digital works are not being preserved in a systematic way. This is partly because digital preservation entails more difficult copyright issues than preservation of non-digital material. All the surveyed countries have some form of exception for preservation activities. However, there is inconsistency in the details between the countries’ laws and uncertainty in how they apply in the digital environment. None of the countries surveyed have a uniform national system yet for collecting digital materials. Technological protection measures and licensing arrangements may, in some cases, present significant practical barriers to preservation. Current approaches to address these barriers are ad hoc and include requesting permissions from individual rights holders and some use of model licence terms that permit preservation. Moreover, as yet, there are no effective solutions to the general issue of orphan works. Recommendations of the study include suggestions for drafting national policies and adapting laws to allow digital preservation to be undertaken as necessary, in accordance with international best practice standards, and for promoting national systems for the collection of digital materials by relevant state and national collecting institutions.

    Full Text Available The goal of the article lies in the study of existing international standards of risk management, an important factor of improvement of risk management in domestic corporations and enterprises and development of recommendations on application of international standards in Ukraine, in particular, within the framework of building corporate systems of risk management. The conducted study shows that approaches on organisation of the process of risk management, used in standards of risk management, are of general character and differ with the degree of detailing. Their undoubted value in development of risk management in Ukraine is identification of a general direction of building corporate systems of risk management in practice. The said approaches at the national and corporate levels of standardisation in Ukraine within the framework of building corporate systems of risk management would allow improvement of risk management in corporations and enterprises. The prospect of further studies of domestic specialists in the field of risk management is development of the domestic standard of risk management with consideration of modern domestic specific features of development of risk management in Ukraine and leading foreign experience.

    Venous thromboembolism (VTE) is a major cause of morbidity and mortality with significant heterogeneity in its management, both within our local practice and in international guidelines. To provide a holistic evaluation of 'real-world' Australian experience in the warfarin era, including how we compare to international guidelines. Retrospective evaluation of VTE from July 2011 to December 2012 at two major hospitals in Melbourne, Australia. These results were compared to recommendations in the international guidelines. A total of 752 episodes involving 742 patients was identified. Contrary to international guidelines, an unwarranted heritable thrombophilia screen was performed in 22.0% of patients, amounting to a cost of AU$29 000. The duration of anticoagulation was longer compared to international recommendations, although the overall recurrence (3.2/100 person-years) and clinically significant bleeding rates (2.4/100 person-years) were comparable to 'real-world' data. Unprovoked VTE (hazard ratio 2.06; P = 0.01) was a risk factor for recurrence, and there was no difference in recurrence between major VTE (proximal deep vein thrombosis (DVT) and/or pulmonary embolism) and isolated distal DVT (3.02 vs 3.94/100 person-years; P = 0.25). Fourteen patients were subsequently diagnosed with malignancy, and patients with recurrent VTE had increased risk of prospective cancer diagnosis (relative risk 6.68; P international guidelines, there remains heterogeneity in the management strategies, including excessive thrombophilia screening and longer duration of anticoagulation. This audit highlights the need for national VTE guidelines, as well as prospective auditing of VTE management, in the direct oral anticoagulant era for future comparison. © 2017 Royal Australasian College of Physicians.

    Full Text Available Early indication of bancruptcy is important for a company. If companies aware of  potency of their bancruptcy, they can take a preventive action to anticipate the bancruptcy. In order to detect the potency of a bancruptcy, a company can utilize a a model of bancruptcy prediction. The prediction model can be built using a machine learning methods. However, the choice of machine learning methods should be performed carefully. Because the suitability of a model depends on the problem specifically. Therefore, in this paper we perform a comparative study of several machine leaning methods for bancruptcy prediction. According to the comparative study, the performance of several models that based on machine learning methods (k-NN, fuzzy k-NN, SVM, Bagging Nearest Neighbour SVM, Multilayer Perceptron(MLP, Hybrid of MLP + Multiple Linear Regression, it can be showed that fuzzy k-NN method achieve the best performance with accuracy 77.5%

    To estimate the relative number of deaths in member countries of the Organisation for Economic Co-operation and Development (OECD) from international terrorism and road crashes. Data on deaths from international terrorism (US State Department database) were collated (1994-2003) and compared to the road injury deaths (year 2000 and 2001 data) from the OECD International Road Transport Accident Database. In the 29 OECD countries for which comparable data were available, the annual average death rate from road injury was approximately 390 times that from international terrorism. The ratio of annual road to international terrorism deaths (averaged over 10 years) was lowest for the United States at 142 times. In 2001, road crash deaths in the US were equal to those from a September 11 attack every 26 days. There is a large difference in the magnitude of these two causes of deaths from injury. Policy makers need to be aware of this when allocating resources to preventing these two avoidable causes of mortality.

    To explore the volume and localization of the internal gross target volume defined using the seroma and/or surgical clips based on the four-dimensional computed tomography (4DCT) during free-breathing. Fifteen breast cancer patients after breast-conserving surgery (BCS) were recruited for EB-PBI. On the ten sets CT images, the gross target volume formed by the clips, the seroma, both the clips and seroma delineated by one radiation oncologist and defined as GTVc, GTVs and GTVc + s, respectively. The ten GTVc, GTVs and GTVc + s on the ten sets CT images produced the IGTVc, IGTVs, IGTVc + s, respectively. The IGTV volume and the distance between the center of IGTVc, IGTVs, IGTVc + s were all recorded. Conformity index (CI), degree of inclusion (DI) were calculated for IGTV/IGTV, respectively. The volume of IGTVc + s were significantly larger than the IGTVc and IGTVs (p < 0.05). There was significant difference between the DIs of IGTVc vs IGTVc + s, the DIs of IGTVs vs IGTVc + s. There was significant difference among the CIs of IGTV/IGTV. The DIs and CIs of IGTV/IGTV were negatively correlated with their centroid distance (r < 0, p < 0.05). There were volume difference and spatial mismatch between the IGTVs delineated based on the surgical clips and seroma. The IGTV defined as the seroma and surgical clips provided the best overall representation of the ‘true’ moving GTV

    2014-01-01

    Full Text Available In June 2013, Mount Fuji was nominated as a UNESCO World Heritage site. Subsequently, a new system was piloted encouraging climbers to make a donation of 1000 JPY to help improve environmental conservation. This research is part of a larger study from 2008 to 2014 monitoring the characteristics and behaviour of Fuji climbers. Specifically, this paper investigates Japanese and international climbers to compare their level of awareness and willingness to pay the new donation. Results revealed broad differences between Japanese and international climbers, with 71% of the latter unaware about the new fee prior to climbing, compared to only 16% of Japanese. 77% of Japanese supported the new fee compared to only 50% of international climbers. These findings seem to suggest that prior awareness is vital for compliance, as cross-analysis showed that among international climbers, 72% of those who knew in advance were willing to pay, compared to 43% of those without prior awareness. The new trial climbing fee will be extended for the entire 2014 season on a 24 hour basis, so these findings have implications for improved management based on a better understanding of market segments and more effective messaging to raise awareness, particularly among foreign climbers.

  6. EFQPSK Versus CERN: A Comparative Study

    2001-01-01

    This report presents a comparative study on Enhanced Feher's Quadrature Phase Shift Keying (EFQPSK) and Constrained Envelope Root Nyquist (CERN) techniques. These two techniques have been developed in recent times to provide high spectral and power efficiencies under nonlinear amplifier environment. The purpose of this study is to gain insights into these techniques and to help system planners and designers with an appropriate set of guidelines for using these techniques. The comparative study presented in this report relies on effective simulation models and procedures. Therefore, a significant part of this report is devoted to understanding the mathematical and simulation models of the techniques and their set-up procedures. In particular, mathematical models of EFQPSK and CERN, effects of the sampling rate in discrete time signal representation, and modeling of nonlinear amplifiers and predistorters have been considered in detail. The results of this study show that both EFQPSK and CERN signals provide spectrally efficient communications compared to filtered conventional linear modulation techniques when a nonlinear power amplifier is used. However, there are important differences. The spectral efficiency of CERN signals, with a small amount of input backoff, is significantly better than that of EFQPSK signals if the nonlinear amplifier is an ideal clipper. However, to achieve such spectral efficiencies with a practical nonlinear amplifier, CERN processing requires a predistorter which effectively translates the amplifier's characteristics close to those of an ideal clipper. Thus, the spectral performance of CERN signals strongly depends on the predistorter. EFQPSK signals, on the other hand, do not need such predistorters since their spectra are almost unaffected by the nonlinear amplifier, Ibis report discusses several receiver structures for EFQPSK signals. It is observed that optimal receiver structures can be realized for both coded and uncoded EFQPSK

    Our objective was to evaluate the frequency and type of malformations associated with gastroschisis in a large pool of international data, to identify malformation patterns, and to evaluate the role of maternal age in non-isolated cases. Case-by-case information from 24 registries, all members of the International Clearinghouse for Birth Defects Surveillance and Research (ICBDSR), were evaluated. After the exclusion of other abdominal wall defects cases were classified as: (a) isolated; (b) recognizable syndrome, chromosomal or not; (c) multiple congenital anomalies (MCA). Our results showed that out of 3,322 total cases 469 non-isolated cases were registered (14.1%): 41 chromosomal syndromes, 24 other syndromes, and 404 MCA. Among MCA four groups of anomalies were most frequent: CNS (4.5%), cardio-vascular (2.5%), limb (2.2%), and kidney anomalies (1.9%). No similar patterns emerged except two patterns resembling limb-body wall complex and OEIS. In both of them the gastroschisis could be however misclassified. Chromosomal trisomies and possibly non-syndromic MCA are associated with an older maternal age more than isolated cases. On consideration of our data and the most valid studies published in the literature, the best estimate of the proportion of gastroschisis associated with major unrelated defects is about 10%, with a few cases associated to recognizable syndromes. Recognized syndromes with gastroschisis seem to be so exceptional that the well documented and validated cases are worth being published as interesting case report. An appropriate case definition in etiological studies should include only isolated gastroschisis after an appropriate definition of isolated and non-isolated cases and a thorough case-by-case review.

    2018-03-01

    Internal friction is frequently found in protein dynamics. Its molecular origin however is difficult to conceptualize. Even unfolded and intrinsically disordered polypeptide chains exhibit signs of internal friction despite their enormous solvent accessibility. Here, we compare four polymer theories of internal friction with experimental results on the intrinsically disordered protein ACTR (activator of thyroid hormone receptor). Using nanosecond fluorescence correlation spectroscopy combined with single-molecule Förster resonance energy transfer (smFRET), we determine the time scales of the diffusive chain dynamics of ACTR at different solvent viscosities and varying degrees of compaction. Despite pronounced differences between the theories, we find that all models can capture the experimental viscosity-dependence of the chain relaxation time. In contrast, the observed slowdown upon chain collapse of ACTR is not captured by any of the theories and a mechanistic link between chain dimension and internal friction is still missing, implying that the current theories are incomplete. In addition, a discrepancy between early results on homopolymer solutions and recent single-molecule experiments on unfolded and disordered proteins suggests that internal friction is likely to be a composite phenomenon caused by a variety of processes.

    In this article we compare United States and European Union support for bilateral and multilateral international trade law. We assess the support for international law of both trading blocs by focusing on the following four dimensions: leadership, consent, compliance and internalization. Although we find strong support for international trade law from both the US and the EU in general, we also witness some variation, most notably in relation to the design of preferential trade agreements (PTAs) and compliance with World Trade Organization (WTO) law. Turning to explaining these (moderate) differences, we argue that outcomes in US trade policy can best be explained by a domestic political factor, namely the direct influence of interest groups. Although the involvement of societal interests also goes a long way in explaining EU behavior, it does not tell the entire story. We posit that, in EU trade policy, institutions are a particular conditioning factor that needs to be stressed. Moreover, we suggest that foreign policy considerations in managing trade relations have characterized EU’s support for international trade law. PMID:27867316

    The question of what deters crime is of both theoretical and practical interest. The present paper focuses on what factors deter minor, non-violent crimes, i.e., dishonest actions that violate the law. Much research has been devoted to testing the effectiveness of legal sanctions on crime, while newer models also include social sanctions (judgment of friends or family) and internal sanctions (feelings of guilt). Existing research suggests that both internal sanctions and, to a lesser extent, legal sanctions deter crime, but it is unclear whether this pattern is unique to Western countries or robust across cultures. We administered a survey study to participants in China, Colombia, Germany, Portugal, and USA, five countries from distinct cultural regions of the world. Participants were asked to report the likelihood of engaging in seven dishonest and illegal actions, and were asked to indicate the probability and severity of consequences for legal, friend, family, and internal sanctions. Results indicated that across countries, internal sanctions had the strongest deterrent effects on crime. The deterrent effects of legal sanctions were weaker and varied across countries. Furthermore, the deterrent effects of legal sanctions were strongest when internal sanctions were lax. Unexpectedly, social sanctions were positively related to likelihood of engaging in crime. Taken together, these results suggest that the relative strengths of legal and internal sanctions are robust across cultures and dishonest actions.

    Teenage pregnancy is a global problem and is considered a high-risk group, in spite of conflicting evidence. Our objective was to compare obstetric outcomes of pregnancy in teenagers and older women. This was a retrospective study of case records of pregnancies from August 2000 to July 2001. Girls aged pregnancy outcomes in older women (19-35 years) in the same hospital. The study took place in the Government General Hospital, Sangli, India, a teaching hospital in rural India, with an annual delivery rate of over 3,500. A total of 386 teenage pregnancies were compared with pregnancies in 3,326 older women. Socioeconomic data, age, number of pregnancies, antenatal care and complications, mode of delivery, and neonatal outcomes were considered. The incidence of teenage pregnancy in the study was 10%. A significant proportion of teenage pregnant mothers were in their first pregnancies. The teenage mothers were nearly three times more at risk of developing anaemia (OR = 2.83, 95% CI = 2.2-3.7, p Teenage mothers were twice as likely to develop hypertensive problems in pregnancy (OR = 2.2, 95% CI = 1.5-3.2, p teenage pregnancies are still a common occurrence in rural India in spite of various legislations and government programmes and teenage pregnancy is a risk factor for poor obstetric outcome in rural India. Cultural practices, poor socioeconomic conditions, low literacy rate and lack of awareness of the risks are some of the main contributory factors. Early booking, good care during pregnancy and delivery and proper utilisation of contraceptive services can prevent the incidence and complications in this high-risk group.

    This work was a comparative study between the responses of three monitors, the NRPB, an acrylic monitor (in thin film geometry) and the aluminum monitor (also thin film geometry) in controlled and mixed environment. The experiments consisted on placing the monitors in a plastic tube, with a radio-226 source internal. Only internal CR-39 plastic detectors were analyzed in this work. It was found that the monitors in thin film geometry had activities response of approximately 15% less than the NRPB monitors. All monitors responded the same way when in controlled environment. Related to the type of material, conductive plastic or dielectric (insulator) plastic, the NRPB, in environments without ventilation, responded in the same way. (author)

    Because of the increased number of bicycle riders and governmental promotions, a recent increase in the construction of bicycle lanes has occurred. We aimed to characterize injuries specific to bicycle lane accidents by comparing them with injuries that occurred on regular roadways. On the basis of our findings, we provide suggestions on proper preventive strategies. We performed a retrospective study on 408 cases obtained between January 1, 2009, and December 31, 2010. Of these cases, 387 met the criterion that the location of the injury could be confirmed by telephone or via review of the patient's chart. Data regarding age, gender, Injury Severity Score, time of the accident, location of the accident, and other characteristics were collected. Data were analyzed using SPSS 12.0K. Of the 387 cases, 204 (52.7%) patients were injured in bicycle lanes and 183 (47.3%) were injured on regular roadways. Comparing cases of bicycle lane injuries and non-bicycle lane injuries, there were no differences in age, day of the week, season, or the time at which the accident occurred. Bicycle helmets were used more frequently in bicycle lane injuries (33.2% vs. 13.7%; p gear or preventing the use of bicycle lanes by pedestrians. More safety education programs are also needed.

    A fine structure of bacteria flagella is an important problem of molecular cell biology. Bacteria flagella are the self-assembled structures that allow to use the flagellum protein in a number of biotechnological applications. However, at present, there is a little information about high resolution scanning probe microscopy study of flagellum structure, in particular, about investigation of Vibrio cholerae flagella. In our lab have been carried out the high resolution comparative investigation of V. cholerae flagella by means of various microscopes: tunneling (STM), scanning force (SFM) and electron transmission. As a scanning probe microscope is used designed in our lab versatile SPM with replaceable measuring heads. Bacteria were grown, fixed and treated according to the conventional techniques. For STM investigations samples were covered with Pt/Ir thin films by rotated vacuum evaporation, in SFM investigations were used uncovered samples. Electron microscopy of the negatively stained bacteria was used as a test procedure.

    Scientific literature shows that anxiety is an important factor in eating disorders. The aim of this case-control study was to compare the anxiety manifestations obtained by means of the Anxiety Situations and Responses Inventory of in a clinical sample of 74 females (46, anorexia nervosa; 28, bulimia) to those obtained by a control group (130 girls without disorders). The between-group ANOVA results showed higher anxiety scores in the clinical group with a medium effect size for the anxiety trait, finding a flat profile (within-group ANOVA) for the three response systems (cognitive, physiological and motor) and the four specific anxiety traits (test, interpersonal, phobic, and daily life situations). Moreover, high scores in anxiety involved a greater risk of being diagnosed with an eating disorder in the 8 bivariate comparisons. The estimations were more precise for cognitive anxiety and for the specific interpersonal anxiety trait.

    Full Text Available Being an important contributor to the final energy consumption, historic buildings built before 1945 have high specific heating energy consumption compared to current energy standards and norms. However, they often cannot be insulated from the outside due to their heritage and culture value. Internal insulation is an alternative. However internal insulation faces challenges related to hygrothermal behaviour leading to mold growth, freezing, deterioration and other risks. The goal of this research is to link hygrothermal simulation results with experimental results for internally insulated historic brick masonry to assess correlation between simulated and measured data as well as the most influential parameters. The study is carried out by both a mathematical simulation tool and laboratory tests of historic masonry with internal insulation with four insulation materials (mineral wool, EPS, wood fiber and granulated aerogel in a cold climate (average 4000 heating degree days. We found disparity between measured and simulated hygrothermal performance of studied constructions due to differences in material parameters and initial conditions of materials. The latter plays a more important role than material parameters. Under a steady state of conditions, the condensate tolerating system varies between 72.7 % and 80.5 % relative humidity, but in condensate limiting systems relative humidity variates between 73.3 % and 82.3 %. The temperature between the masonry wall and all insulation materials has stabilized on average at +10 °C. Mold corresponding to Mold index 3 was discovered on wood fiber mat.

    2017-02-01

    Full Text Available Background: Efficiency measurement by means of data envelopment analysis (DEA in the non-profit sector has focused on the so-called Stage I of non-profit organisations, namely, fundraising efforts (which are the most influential determinants of raising funds in order to increase the amount of contributions. However, for the so-called Stage II of non-profit organisations, namely, spending the achieved resources to program services delivery, DEA studies are very scarce. In attempting to address this research gap and to the best of our knowledge, this investigation is the first study that applies DEA to the assessment of international cooperation schemata. Consequently, we offer a significant contribution to the literature by overcoming the limitations of other techniques used to assess the efficiency and providing new insight into the efficiency of targeted different international cooperation schemata (ICS in international cooperation development projects. Aim: The purpose of this study is to evaluate and compare the efficiency of the ICS of developmental projects funded by the Spanish Agency for International Cooperation for Development. Setting: Our setting is composed of different international cooperation projects funded with different schemata by the Spanish Agency for International Cooperation for Development between 2002 and 2006 in two African countries that are top priority targets of Spanish international aid: Morocco, and Mozambique. Methods: Using a sample of 48 international cooperation projects carried out in two African countries considered priorities in the Spanish Cooperation Master Plan, we analyse project efficiency using DEA. Results: The findings suggest that some schemata are more efficient than others when applied to international cooperation projects (ICS. Specifically, we find that permanent open-call subsidies are more efficient than non-governmental development organisation subsidies. Conclusion: Measures for evaluating

    2017-01-01

    While considerable progress has been made in understanding the way particular aspects of internal migration, such as its intensity, age profile and spatial impact, vary between countries around the world, little attention to date has been given to establishing how these dimensions of migration interact in different national settings. We use recently developed measures of internal migration that are scale-independent to compare the overall intensity, age composition, spatial impact, and distance profile of internal migration in 19 Latin American countries. Comparisons reveal substantial cross-national variation but cluster analysis suggests the different dimensions of migration evolve systematically to form a broad sequence characterised by low intensities, young ages at migration, unbalanced flows and high friction of distance at lower levels of development, trending to high intensities, an older age profile of migration, more closely balanced flows and lower friction of distance at later stages of development. However, the transition is not linear and local contingencies, such as international migration and political control, often distort the migration-development nexus, leading to unique migration patterns in individual national contexts.

  12. Comparative studies of groundwater vulnerability assessment

    Science.gov (United States)

    Maria, Rizka

    2018-02-01

    Pollution of groundwater is a primary issue because aquifers are susceptible to contamination from land use and anthropogenic impacts. Groundwater susceptibility is intrinsic and specific. Intrinsic vulnerability refers to an aquifer that is susceptible to pollution and to the geological and hydrogeological features. Vulnerability assessment is an essential step in assessing groundwater contamination. This approach provides a visual analysis for helping planners and decision makers to achieve the sustainable management of water resources. Comparative studies are applying different methodologies to result in the basic evaluation of the groundwater vulnerability. Based on the comparison of methods, there are several advantages and disadvantages. SI can be overlaid on DRASTIC and Pesticide DRASTIC to extract the divergence in sensitivity. DRASTIC identifies low susceptibility and underestimates the pollution risk while Pesticide DRASTIC and SI represents better risk and is recommended for the future. SINTACS method generates very high vulnerability zones with surface waters and aquifer interactions. GOD method could be adequate for vulnerability mapping in karstified carbonate aquifers at small-moderate scales, and EPIK method can be used for large scale. GOD method is suitable for designing large area such as land management while DRASTIC has good accuracy and more real use in geoenvironmental detailed studies.

    Wichmann, K.

    2009-01-01

    Recently, Letters of Intent (LoI) for experiments at the International Linear Collider (ILC) have been submitted. Among the three proposals is the International Large Detector (ILD) concept which is at the focus of these studies. From various subjects addressed in the LoI, a wide spectrum of studies of SUSY particle properties is presented here. Most of them are benchmark reactions for the ILC and can be used both in physics studies and in work on detector design and optimization, respectively. All studies were performed with a full detector simulation using GEANT4, which is a great improvement compared to the previous results with much less detailed, so called f ast , simulation (SIMDET). The importance of this improved simulation is reflected in the results. The presented analyzes have been chosen to be the most challenging for the detector to study its performance and guide the detector development. Additionally an important problem of unavoidable beam induced backgrounds at linear colliders is addressed and ways of reducing its impact on physics studies are shown for an example SUSY analysis.

    1989-01-01

    Fourteen patients with internal carotid artery (ICA) occlusion identified by cerebral angiography were studied for clinical features, computed tomographic findings, collateral circulation and risk factors. Eleven patients were males, and at age distribution it occurred more frequently in patients over 50 years to 60 years of age rather than other ages. As for the risk factors of cerebral infarction, smoking was more frequent in patients with thrombosis, and heart disease was more common in those with embolism. Stroke occurred progressively in patients with thrombosis whereas it occurred suddenly in those with embolism. The consciousness was more severely disturbed in patients with embolism than in those with thrombosis. On neuro-radiological findings, in the patients with thrombosis, the infarcted area on CT were small and emerged as deep or watershed types, and on the angiograms, occlusion at carotid bifurcation were found more frequently and the collateral circulation were well developed. In those with embolism, the infarcted areas were large and emerged as cortical types, and on the angiograms, occlusions were observed more frequently in the intracranial portion and collateral circulation were poorly developed. In many patients with thrombosis, platelet aggregation, hematocrit and blood viscosity increased, but in those with embolism did not. (author)

    2017-12-01

    Full Text Available On 1st January 2015 the Eurasian Economic Union (EAEU - a new integration block comprising initially Belarus, Kazakhstan, and Russia, and later that year also Armenia and Kyrgyzstan - appeared on the world map. This paper endeavors to identify the EAEU countries’ long-term international comparative advantages within four basic groups of goods according to the OECD classification of manufacturing industries based on technology intensity. The analysis, using B. Balassa’s RCA methodology and covering the years 2000-2014, indicates that these countries lack competitiveness, with none of them possessing any RCAs in the high-technology category whereas in the medium-hightechnology category - only Belarus. In contrast, all the EAEU countries fared the best in the medium-low-technology category, which is mostly attributable to the resources-based character of their economies. Surprisingly, dramatically low international competitiveness was recorded by Kazakhstan and Russia.

    Coan, Mary R.; Hirshorn, Steven R.; Moreland, Robert

    2015-01-01

    The NASA Protoflight Research Initiative is an internal NASA study conducted within the Office of the Chief Engineer to better understand the use of Protoflight within NASA. Extensive literature reviews and interviews with key NASA members with experience in both robotic and human spaceflight missions has resulted in three main conclusions and two observations. The first conclusion is that NASA's Protoflight method is not considered to be "prescriptive." The current policies and guidance allows each Program/Project to tailor the Protoflight approach to better meet their needs, goals and objectives. Second, Risk Management plays a key role in implementation of the Protoflight approach. Any deviations from full qualification will be based on the level of acceptable risk with guidance found in NPR 8705.4. Finally, over the past decade (2004 - 2014) only 6% of NASA's Protoflight missions and 6% of NASA's Full qualification missions experienced a publicly disclosed mission failure. In other words, the data indicates that the Protoflight approach, in and of it itself, does not increase the mission risk of in-flight failure. The first observation is that it would be beneficial to document the decision making process on the implementation and use of Protoflight. The second observation is that If a Project/Program chooses to use the Protoflight approach with relevant heritage, it is extremely important that the Program/Project Manager ensures that the current project's requirements falls within the heritage design, component, instrument and/or subsystem's requirements for both the planned and operational use, and that the documentation of the relevant heritage is comprehensive, sufficient and the decision well documented. To further benefit/inform this study, a recommendation to perform a deep dive into 30 missions with accessible data on their testing/verification methodology and decision process to research the differences between Protoflight and Full Qualification

    2011-01-01

    Highlights: → Welding processes are used to reconstitute previously tested Charpy specimens. → Stud welding is preferred for a quick installation, almost immediately operational. → Friction welding produces better quality welds, but requires a development effort. - Abstract: Reconstitution techniques are often used to allow material from previously fractured Charpy-V specimens to be reused for additional experiments. This paper presents a comparative experimental study of various reconstitution techniques and evaluates the feasibility of these methods for future use in shielded cells. The following techniques were investigated: arc stud welding, 6.0 kW CO 2 continuous wave laser welding, 4.5 kW YAG continuous wave laser welding and friction welding. Subsize Charpy specimens were reconstituted using a 400 W YAG pulsed wave laser. The best result was obtained with arc stud welding; the resilience of the reconstituted specimens and the load-displacement curves agreed well with the reference specimens, and the temperature elevation caused by the welding process was limited to the vicinity of the weld. Good results were also obtained with friction welding; this process led to the best quality welds. Laser welding seems to have affected the central part of the specimens, thus leading to different resilience values and load-displacement curves.

    The midventilation (midV) approach can be used to take respiratory-induced pancreatic tumor motion into account during radiation therapy. In this study, the dosimetric consequences for organs at risk and tumor coverage of using a midV approach compared with using an internal target volume (ITV) were investigated. For each of the 18 patients, 2 treatment plans (25 × 2.0 Gy) were created, 1 using an ITV and 1 using a midV approach. The midV dose distribution was blurred using the respiratory-induced motion from 4-dimensional computed tomography. The resulting planning target volume (PTV) coverage for this blurred dose distribution was analyzed; PTV coverage was required to be at least V95% >98%. In addition, the change in PTV size and the changes in V10Gy, V20Gy, V30Gy, V40Gy, Dmean and D2cc for the stomach and for the duodenum were analyzed; differences were tested for significance using the Wilcoxon signed-rank test. Using a midV approach resulted in sufficient target coverage. A highly significant PTV size reduction of 13.9% (P<.001) was observed. Also, all dose parameters for the stomach and duodenum, except the D2cc of the duodenum, improved significantly (P≤.002). By using the midV approach to account for respiratory-induced tumor motion, a significant PTV reduction and significant dose reductions to the stomach and to the duodenum can be achieved when irradiating pancreatic tumors.

  7. Frameworks for comparing emissions associated with production, consumption, and international trade.

    While the problem of climate change is being perceived as increasingly urgent, decision-makers struggle to agree on the distribution of responsibility across countries. In particular, representatives from countries hosting emissions-intensive exporting industries have argued that the importers of emissions-intensive goods should bear the responsibility, and ensuing penalties. Indeed, international trade and carbon leakage appear to play an increasingly important role in the carbon emissions debate. However, definitions of quantities describing the embodiment of carbon emissions in internationally traded products, and their measurement, have to be sufficiently robust before being able to underpin global policy. In this paper we critically examine a number of emissions accounting concepts, examine whether the ensuing carbon balances are compatible with monetary trade balances, discuss their different interpretations, and highlight implications for policy. In particular, we compare the emissions embodied in bilateral trade (EEBT) method which considers total trade flows with domestic emission intensities, with the multi-regional input-output (MRIO) method which considers trade only into final consumption with global emission intensities. If consumption-based emissions of different countries were to be compared, we would suggest an MRIO approach because of the global emissions coverage inherent in this method. If trade-adjusted emission inventories were to be compared, we would suggest an EEBT approach due to the consistency with a monetary trade balance.

  8. Important Questions Of Comparative Studies In Asian Countries

    2015-06-01

    Full Text Available The issue of the “identity” of comparative education as a field of study or a discipline has been discussed for decades. Yet a kind of systematic structure that provides the basic principles for a coherent exposition of the field remains open. “Comparative education” is no longer conceived as an imaginary field’s coherence but, rather in terms of distinct branches of comparative and international studies in education and their underlying issues. Such an understanding is fostered through a deepened awareness of the basic problems, and successive solutions, constitutive of the emergence and further conformations of the comparative approach in education and the social sciences. Thus, academic journal publications of the past decade to shape education policy research within an Asia-Pacific context have been analyzed. Facts of increasing research collaboration, growing policy evaluation research, and growing attention to higher education have been presented. Significant difference in research impact and diffusion between Asia-Pacific and American education policy studies has been shown. Perspectives for future research directions in education policy research in an Asia-Pacific context have been suggested.

  9. Globalisation plus Comparative and International Education: Towards a Theory of the Confluence

    Full Text Available This paper attempts to contribute to ways by which confluence, referring to a meeting point for the different agents to cooperate and communicate on education policy processes, can be understood. Pertinent national education policies in countries receiving aid, in particular, are formed and implemented in a complex nexus. Cultural and context sensitivity can be stimulated through a thorough understanding of this confluence, which subsequently can enable the different policy agents, which function at this meeting point, collaborate to alleviate some of the educational challenges. Comparative and international education, in this respect, has a significant role to play.

  12. The ‘Landscape’ of Nuclear Safeguards: A Comparative Analysis of the International and Regional Systems

    International Nuclear Information System (INIS)

    Colussi, I.A.

    2015-01-01

    The notion of “nuclear non-proliferation” is twofold. It refers to: (a) reduction of the number of existing arsenals (vertical non-proliferation), and (b) containment of the number of States that possess nuclear weapons, or control of non-state actors (horizontal non-proliferation). At the international law level, as vertical non-proliferation, there are bilateral or multilateral agreements that ban weapons of mass destruction in certain areas (e.g.: Nuclear–Weapon– Free Zones treaties). With respect to horizontal non-proliferation, beyond the Nuclear-Weapon-Free Zones approach, the main legal text for addressing the issue is the Treaty on the Non-Proliferation of Nuclear Weapons (NPT). For the implementation of the principles contained in the NPT, a “nuclear safeguards” system has been created, and the International Atomic Energy Agency (IAEA) has been assigned the role of the nuclear “watchdog” for the NPT. However, along with this international system of safeguards, there are regional safeguards bodies: (a) the European Atomic Energy Community (EURATOM) model is the cornerstone of non-proliferation in the EU, while (b) the Brazilian-Argentine Agency for Accounting for and Control of Nuclear Materials (ABACC) controls nuclear activities in Brazil and Argentina. Moreover, the existing nuclear weapons free-zone treaties contain safeguards provisions that are additional or complementary to IAEA safeguards. For instance, (a) the Agency for the Prohibition of Nuclear Weapons in Latin America and the Caribbean (OPANAL) works for the implementation of Tlatelolco Treaty, (b) the African Commission on Nuclear Energy relates to Pelindaba Treaty, and (c) a Consultative Committee of the Parties is appointed in the context of Raratonga Treaty. The paper aims at critically analysing the different safeguards systems adopted at the international and regional level, through the adoption of a comparative approach. (author)

    In acute stroke patients, thrombolysis is one gold standard therapy option within the first four hours after the ischemic event. A contraindication for thrombolysis is an International Normalized Ratio (INR) value >1.7. Since time is brain, rapid and reliable INR results are fundamental. Aim was to compare INR values determined by central laboratory (CL) analyzer and Point-of-Care Testing(POCT)-device and to evaluate the quality of POCT performance in cases of potential therapeutic thrombolysis at a certified stroke unit. In 153 patients INR measurements using POCT-devices (HEMOCHRON Signature Elite®) were compared to INR measurements (BCS®XP) performed at the central laboratory. Outlier evaluation was performed regarding the critical thrombolysis cut-off. Overall, we demonstrated a significant correlation (r = 0.809, p75 years. POCT-INR measurements based on our POCT concept are suitable to determine INR values in critical stroke patients. Nevertheless, outlier evaluation is mandatory.

    Building materials and their additives contain radioactive isotopes, which can increase both external and internal radioactive exposures of humans. In this study Hungarian natural (adobe) and artificial (brick, concrete, coal slag, coal slag concrete and gas silicate) building materials were examined. We qualified 40 samples based on their radium equivalent, activity concentration, external hazard and internal hazard indices and the determined threshold values of these parameters. Absorbed dose rate and annual effective dose for inhabitants living in buildings made of these building materials were also evaluated. The calculations are based on (226)Ra, (232)Th and (40)K activity concentrations determined by gamma-ray spectrometry. Measured radionuclide concentrations and hence, calculated indices and doses of artificial building materials show a rather disparate distribution compared to adobes. The studied coal slag samples among the artificial building materials have elevated (226)Ra content. Natural, i.e. adobe and also brick samples contain higher amount of (40)K compared to other artificial building materials. Correlation coefficients among radionuclide concentrations are consistent with the values in the literature and connected to the natural geochemical behavior of U, Th and K elements. Seven samples (coal slag and coal slag concrete) exceed any of the threshold values of the calculated hazard indices, however only three of them are considered to be risky to use according to the fact that the building material was used in bulk amount or in restricted usage. It is shown, that using different indices can lead to different conclusions; hence we recommend considering more of the indices at the same time when building materials are studied. Additionally, adding two times their statistical uncertainties to their values before comparing to thresholds should be considered for providing a more conservative qualification. We have defined radon hazard portion to point

    2014-01-01

    Investigations have been made of four new radiation dosimetry EPR candidates from the same family of materials: sulfamic acid, sulfanillic acid, homotaurine, and taurine. Mass energy attenuation coefficients, mass stopping power values and the time dependence of the radiation induced radicals are compared. Also investigated are the microwave saturation behavior and the effect of applied modulation amplitude on both peak-to-peak line width (W PP ) and peak-to-peak signal height (H PP ). The dosimeters are characterized by simple spectra and stable radiation-induced radicals over reasonable durations, especially in taurine dosimeters. Sulfamic acid dosimeters possessed the highest sensitivity followed by taurine and homotaurine and sulfanillic. - Highlights: ► Several EPR dosimeters were suggested based on SO 3 − radical. ► Taurine, homotaurine, sulfanilic, and sulfamic acid all possess simple EPR spectra. ► Dosimeters were compared to each other in terms of the dosimetric point of view. ► Energy dependence curves of the selected dosimeters were compared to eachother

  10. How Two Small Pharmacy Schools' Competency Standards Compare with an International Competency Framework and How Well These Schools Prepare Students for International Placements.

    Science.gov (United States)

    Hawboldt, John; Nash, Rose; FitzPatrick, Beverly

    2017-03-06

    International standards of pharmacy curricula are necessary to ensure student readiness for international placements. This paper explores whether curricula from two pharmacy programs, in Australia and Canada, are congruent with international standards and if students feel prepared for international placements. Nationally prescribed educational standards for the two schools were compared to each other and then against the International Pharmaceutical Federation (FIP) Global Competency Framework. Written student reflections complemented this analysis. Mapping results suggested substantial agreement between the FIP framework and Australia and Canada, with two gaps being identified. Moreover, the students felt their programs prepared them for their international placements. Despite differences in countries, pharmacy programs, and health-systems all students acclimatized to their new practice sites. Implications are that if pharmacy programs align well with FIP, pharmacists should be able to integrate and practise in other jurisdictions that also align with the FIP. This has implications for the mobility of pharmacy practitioners to countries not of their origin of training.

    HgBa 2 CaCu 2 O 6+δ (Hg-1212) thin films were fabricated by exchanging the TI cations in TlBa 2 CaCu 2 O 7-δ (Tl-1212) thin films with Hg cations, causing a 30-K increase in Tc. To determine how this exchange effects such a Tc increase, the irreversibility lines, temperature dependence of critical current density, and temperature dependence of Hall angle of Hg-1212 and T1-1212 thin films were measured and then compared. The results strongly suggest that the Tc shift is caused by a doubling of charge carrier density

    Economic development and growth depend on growing levels of resource use, and result in environmental impacts from large scale resource extraction and emissions of waste. In this study, we examine the resource dependency of economic activities over the past several decades for a set of countries comprising developing, emerging and mature industrialized economies. Rather than a single universal industrial development pathway, we find a diversity of economic dependencies on material use, made evident through cluster analysis. We conduct tests for relative and absolute decoupling of the economy from material use, and compare these with similar tests for decoupling from carbon emissions, both for single countries and country groupings using panel analysis. We show that, over the longer term, emerging and developing countries tend to have significantly larger material-economic coupling than mature industrialized economies (although this effect may be enhanced by trade patterns), but that the contrary is true for short-term coupling. Moreover, we demonstrate that absolute dematerialization limits economic growth rates, while the successful industrialization of developing countries inevitably requires a strong material component. Alternative development priorities are thus urgently needed both for mature and emerging economies: reducing absolute consumption levels for the former, and avoiding the trap of resource-intensive economic and human development for the latter.

    The purpose of this study was to compare movement pattern, fatigue development, and heart rate (HR) for top-class elite female players when playing international (INT) vs. domestic league games (DOM). Video-based time-motion analyses and HR recordings were performed on 17 players during INT and DOM. The distances covered in high-intensity running (HIR) and sprinting were longer (p game types, the amount of HIR was reduced by 24-27% (p game. The midfielders covered longer (p game and in the most intense 5-minute period of the games, whereas no differences were observed between the game types for defenders. No difference in the HR response was found between INT and DOM. In conclusion, more HIR and sprinting occur in international compared with domestic games, which may affect the fatigue development for players in physically demanding roles. Thus, our results are important to coaches to prepare players to meet the challenges of international soccer games and show that the ability to perform intense intermittent exercise should be trained regularly in elite female players.

    In the past 17 years neonatal mortality survey has provided important data on the trends in deaths of all live born infants born in Southern Ireland who are greater than 500 g birth weight and who die within the first 28 days of life. The aims of this study were to report neonatal mortality data for Southern Ireland for 2004, to examine trends in neonatal mortality over the past 17 years and compare Irish Neonatal Mortality rates to other countries around the world. The neonatal mortality rate for 2004 was 2.9\\/1000 with a corrected NMR of 1.9\\/1000. The response rate to the survey was 100%. Prematurity is now the leading cause of neonatal mortality representing a change from previous years. Deaths related to asphyxia have remained largely unchanged. When compared to international figures Ireland compares favourably to other countries around the world.

  5. Comparative analyses for selected clean coal technologies in the international marketplace

    Szpunar, C.B.; Gillette, J.L.

    1990-07-01

    Clean coal technologies (CCTs) are being demonstrated in research and development programs under public and private sponsorship. Many of these technologies could be marketed internationally. To explore the scope of these international opportunities and to match particular technologies with markets appearing to have high potential, a study was undertaken that focused on seven representative countries: Italy, Japan, Morocco, Turkey, Pakistan, the Peoples' Republic of China, and Poland. The results suggest that there are international markets for CCTs and that these technologies can be cost competitive with more conventional alternatives. The identified markets include construction of new plants and refurbishment of existing ones, especially when decision makers want to decrease dependence on imported oil. This report describes potential international market niches for U.S. CCTs and discusses the status and implications of ongoing CCT demonstration activities. Twelve technologies were selected as representative of technologies under development for use in new or refurbished industrial or electric utility applications. Included are the following: Two generic precombustion technologies: two-stage froth-flotation coal beneficiation and coal-water mixtures (CWMs); Four combustion technologies: slagging combustors, integrated-gasification combined-cycle (IGCC) systems, atmospheric fluidized-bed combustors (AFBCs), and pressurized fluidized-bed combustors (PFBCs); and Six postcombustion technologies: limestone-injection multistage burner (LIMB) systems, gas-reburning sorbent-injection (GRSI) systems, dual-alkali flue-gas desulfurization (FGD), spray-dryer FGD, the NOXSO process, and selective catalytic reduction (SCR) systems. Major chapters of this report have been processed separately for inclusion on the data base.

    Different methods for the determination of the mechanical durability (DU) of pellets and briquettes were compared by international round robin tests including different laboratories. The DUs of five briquette and 26 pellet types were determined. For briquettes, different rotation numbers of a prototype tumbler and a calculated DU index are compared. For pellets testing, the study compares two standard methods, a tumbling device according to ASAE S 269.4, the Lignotester according to ONORM M 7135 and a second tumbling method with a prototype tumbler. For the tested methods, the repeatability, the reproducibility and the required minimum number of replications to achieve given accuracy levels were calculated. Additionally, this study evaluates the relation between DU and particle density. The results show for both pellets and briquettes, that the measured DU values and their variability are influenced by the applied method. Moreover, the variability of the results depend on the biofuel itself. For briquettes of DU above 90%, five replications lead to an accuracy of 2%, while 39 replications are needed to achieve an accuracy of 10%, when briquettes of DU below 90% are tested. For pellets, the tumbling device described by the ASAE standard allows to reach acceptable accuracy levels (1%) with a limited number of replications. Finally, for the tested pellets and briquettes no relation between DU and particle density was found. (author)

In order to know the void fraction axial distribution it is necessary to determine the net generation of vapour and the fluid temperature distribution in the slightly sub-cooled boiling region. It was verified that the net generation of vapour was well represented by the Saha-Zuber model. The selected models for the void fraction calculation present adequate results but with a tendency to super-estimate the experimental results, in particular the homogeneous models. The drift flux model is recommended, followed by the Armand and Smith models. (F.E.) [pt

  8. Clinical methods of goniometry: a comparative study.

    1992-01-01

    This investigation compared the reliability and interchangeable use of three currently available goniometers--a universal goniometer, a fluid goniometer, and an electrogoniometer. Three consecutive readings of the active range of movement of the right elbow joint were taken from each of 23 healthy female volunteers; three experienced observers each used each type of goniometer on two occasions. A balanced experimental design was used to eliminate order effects with respect to subject, tester, or goniometer, and a rigid protocol was employed to reduce error due to diurnal or methodological variations. The results show that there are significant differences between the goniometers used, the testers, and the replications. Significant interaction effects also exist between the goniometers and the occasion, the goniometers and the testers, and the testers and replications. The data suggest that the interchangeable use of different types of goniometer in a clinical setting is inadvisable.

    Full Text Available The article describes test results that provided the ground to define and evaluate basic photometric, colorimetric and electric parameters of selected, widely available light sources, which are equivalent to a traditional incandescent 60-Watt light bulb. Overall, one halogen light bulb, three compact fluorescent lamps and eleven LED light sources were tested. In general, it was concluded that in most cases (branded products, in particular the measured and calculated parameters differ from the values declared by manufacturers only to a small degree. LED sources prove to be the most beneficial substitute for traditional light bulbs, considering both their operational parameters and their price, which is comparable with the price of compact fluorescent lamps or, in some instances, even lower.

    Oceanic top predators have ecological, social and economic value of global significance. These wide-ranging marine species, which include sharks, tunas and billfishes, marine mammals, turtles and seabirds, are the focus of international research attention under the Climate Impacts on Oceanic Top Predators (CLIOTOP) science programme, one of the Integrated Marine Biosphere Research (IMBeR) projects. Over more than a decade, research conducted under CLIOTOP has involved scientists from more than 30 countries, with international collaboration increasing markedly over time, and comparative analyses resulting in new knowledge and understanding of oceanic top predators. This special issue presents 27 papers arising from the 3rd CLIOTOP symposium, held in San Sebastián, Spain in September 2015, spanning topics such as conservation biology, trophic ecology, fisheries science, climate change, and adaptive management. The maturation and synthesis of CLIOTOP's collaborative research is now resulting in real-world management applications and improving understanding of potential ecological and socio-economic impacts of climate change in oceanic systems. The ultimate CLIOTOP goal of preparing both climate-sensitive predator populations and the human societies dependent on them for the impending impacts of climate change is now within reach.

    2015-04-01

    Full Text Available The primary goal of this paper is to comprehend the fundamental organizational differences between Brazilian franchise chains that only operate in the home market and Brazilian franchise chains that operate internationally. The sample chosen for this study comprehends 96 Brazilian franchises operating in the home market and 67 franchises with international operations; logistic regression was used to analyze data obtained from these sources. Our findings suggest that the development of a brand in international operations can be strategic for certain Brazilian franchise chains; this seems to be, however, a scarce resource for many franchises and it could be developed through international operations. With regard to the fees charged, the outcomes demonstrate that Brazilian franchises with international operations tend to charge lower fees from its franchisees to install new units. Regarding the monitoring and control of franchises, there is evidence that the monitoring capability is one of the determining factors in the development of Brazilian franchises international operations.

    Full Text Available Stereoisomers of the monoterpene epoxycarvone (EC, namely (+-cis-EC, (−-cis-EC, (+-trans-EC, and (−-trans-EC, were comparatively evaluated for anticonvulsant activity in specific methodologies. In the pentylenetetrazole (PTZ-induced anticonvulsant test, all of the stereoisomers (at 300 mg/kg increased the latency to seizure onset, and afforded 100% protection against the death of the animals. In the maximal electroshock-induced seizures (MES test, prevention of tonic seizures was also verified for all of the isomers tested. However, the isomeric forms (+ and (−-trans-EC showed 25% and 12.5% inhibition of convulsions, respectively. In the pilocarpine-induced seizures test, all stereoisomers demonstrated an anticonvulsant profile, yet the stereoisomers (+ and (−-trans-EC (at 300 mg/kg showed a more pronounced effect. A strychnine-induced anticonvulsant test was performed, and none of the stereoisomers significantly increased the latency to onset of convulsions; the stereoisomers probably do not act in this pathway. However, the stereoisomers (+-cis-EC and (+-trans-EC greatly increased the latency to death of the animals, thus presenting some protection. The four EC stereoisomers show promise for anticonvulsant activity, an effect emphasized in the isomers (+-cis-EC, (+-trans-EC, and (−-trans-EC for certain parameters of the tested methodologies. These results serve as support for further research and development of antiepileptic drugs from monoterpenes.

  11. Earthquake correlations and networks: A comparative study

    International Nuclear Information System (INIS)

    Krishna Mohan, T. R.; Revathi, P. G.

    2011-01-01

    We quantify the correlation between earthquakes and use the same to extract causally connected earthquake pairs. Our correlation metric is a variation on the one introduced by Baiesi and Paczuski [M. Baiesi and M. Paczuski, Phys. Rev. E 69, 066106 (2004)]. A network of earthquakes is then constructed from the time-ordered catalog and with links between the more correlated ones. A list of recurrences to each of the earthquakes is identified employing correlation thresholds to demarcate the most meaningful ones in each cluster. Data pertaining to three different seismic regions (viz., California, Japan, and the Himalayas) are comparatively analyzed using such a network model. The distribution of recurrence lengths and recurrence times are two of the key features analyzed to draw conclusions about the universal aspects of such a network model. We find that the unimodal feature of recurrence length distribution, which helps to associate typical rupture lengths with different magnitude earthquakes, is robust across the different seismic regions. The out-degree of the networks shows a hub structure rooted on the large magnitude earthquakes. In-degree distribution is seen to be dependent on the density of events in the neighborhood. Power laws, with two regimes having different exponents, are obtained with recurrence time distribution. The first regime confirms the Omori law for aftershocks while the second regime, with a faster falloff for the larger recurrence times, establishes that pure spatial recurrences also follow a power-law distribution. The crossover to the second power-law regime can be taken to be signaling the end of the aftershock regime in an objective fashion.

    2011-01-01

    Full Text Available Background: Conjunctivitis of the newborn is defined as hyperemia and eye discharge in the neonates and is a common infection occurring in the neonates in the first month of life. In the United States, the incidence of neonatal conjunctivitis ranges from 1-2%, in India, the prevalence is 0.5-33% and varies in the world from 0.9-21% depending on the socioeconomic status. Aim: To study the organisms causing conjunctivitis of the newborn and to correlate the etiology with the mode of delivery. Design: Single center, prospective, observational study. Materials and Methods: A total of 300 mothers and their newborns, born over a period of one year, were included in the study. Of these 200 newborns were delivered through vaginal route (Group A and 100 (Group B delivered by lower segment caesarean section (LSCS. At the time of labour, high vaginal swabs were taken from the mothers. Two conjunctival swabs each from both eyes of the newborn were collected at birth and transported to Microbiology department in a candle jar immediately. Results: Eight babies in Group A, developed conjunctivitis at birth. None of the babies in Group B developed conjunctivitis, this difference was statistically highly significant (P<0.000. The organisms found in the conjunctiva of the newborns in Group A were Coagulase negative Staphylococcus, α hemolytic Streptococcus, Escherichia coli and Pseudomonas spps. However, the commonest organism leading to conjunctivitis in the newborn in this study was Coagulase negative Staphylococcus. It was observed that the mothers of 5 out of 8 babies (60% developing conjunctivitis gave history of midwife interference and premature rupture of membranes so the presence of risk factors contribute to the occurrence of conjunctivitis in the newborn. Conclusions: It is inferred that the mode of delivery and the presence of risk factors is responsible for conjunctivitis in the newborn.

    2015-07-01

    Full Text Available During the recent financial crisis of insurance domain, there were imposed new aspects that have to be taken into account concerning the risks management and surveillance activity. The insurance societies could develop internal models in order to determine the minimum capital requirement imposed by the new regulations that are to be adopted on 1 January 2016. In this respect, the purpose of this research paper is to offer a real presentation and comparing with the main solvency regulation systems used worldwide, the accent being on their common characteristics and current tendencies. Thereby, we would like to offer a better understanding of the similarities and differences between the existent solvency regimes in order to develop the best regime of solvency for Romania within the Solvency II project. The study will show that there are clear differences between the existent Solvency I regime and the new approaches based on risk and will also point out the fact that even the key principles supporting the new solvency regimes are convergent, there are a lot of approaches for the application of these principles. In this context, the question we would try to find the answer is "how could the global solvency models be useful for the financial surveillance authority of Romania for the implementation of general model and for the development of internal solvency models according to the requirements of Solvency II" and "which would be the requirements for the implementation of this type of approach?". This thing makes the analysis of solvency models an interesting exercise.

  19. The distinct effects of internalizing weight bias: An experimental study.

    Pearl, Rebecca L; Puhl, Rebecca M

    2016-06-01

    Both experiencing and internalizing weight bias are associated with negative mental and physical health outcomes, but internalization may be a more potent predictor of these outcomes. The current study aimed to differentiate between causal effects of experiencing versus internalizing weight bias on emotional responses and psychological well-being. Adults with overweight/obesity (N=260) completed an online experiment in which they were randomly assigned to focus on either the experience or internalization of weight bias, and completed measures of affect, self-esteem, and body dissatisfaction. Results indicated that the Internalization condition led to more negative affect, less positive affect, and lower self-esteem than the Experience condition. The Internalization condition also led to heightened body dissatisfaction among men, but not women. These findings suggest that weight bias internalization may be a stronger predictor of poor mental and physical health than experiences alone, and carry implications for developing weight bias interventions.

    Tumoural portal vein thrombosis (PVT) is a major prognostic factor in hepatocellular carcinoma (HCC). The efficacy of sorafenib, the only treatment approved at an advanced stage, is limited. Based on previous data, selective internal radiation therapy (SIRT), or {sup 90}Y radioembolization, seems an interesting option. We aimed to compare both treatments in this population. We retrospectively compared patients treated in two centres for HCC with tumoural PVT. We compared overall survival (OS) between patients treated with SIRT and patients treated with sorafenib. Analyses were performed before and after 1:1 matching with a propensity score for controlling indication bias, using a Cox proportional hazards model. A total of 151 patients were analysed, 34 patients treated with SIRT and 117 patients treated with sorafenib only. In the whole population, SIRT was associated with a higher median OS as compared with sorafenib: 18.8 vs 6.5 months (log-rank p < 0.001). There was an imbalance of baseline characteristics between patients treated by SIRT and sorafenib, which justified patient matching with use of a propensity score: 24 patients treated with SIRT could be matched with 24 patients treated with sorafenib. OS was estimated with a median of 26.2 vs 8.7 months in patients treated with SIRT vs sorafenib, respectively (log-rank p = 0.054). Before and after patient matching, the adjusted hazard ratio related to treatment by SIRT was estimated at 0.62 [95 % confidence interval (CI) 0.39-0.97] (p = 0.037) and 0.40 (95 % CI 0.19-0.82) (p = 0.013), respectively. SIRT seems more effective than sorafenib in patients presenting with HCC and tumoural PVT. This hypothesis is being tested in prospective randomized trials. (orig.)

    According to the world's prevalence rate, alcoholism is in the third place after heart and blood vessel diseases and malignant tumors. With the development of neuroscience, the causes of alcoholism's biological etiologic sources are still being studied. Considering that dermatoglyphics are highly determined by heritage, we contemplated the possibilities of their discrimination in alcoholic patients in relation to phenotypically healthy subjects. We analyzed the quantitative and qualitative dermatoglyphics properties of 100 alcoholic patients without psychiatric comorbidity, who have been cured in the Psychiatric Hospital Sveti Ivan two or more times, and those of 100 phenotypically healthy men. Through the t-test we evaluated the heterogeneity of the examined groups. Results showed a statistically significant difference on five examined variables. In the calculation of fluctuating asymmetry measure, we found no statistically significant differences in the correlation of values of the right and the left hand on the tested variables, beside one. Chi-square tests showed that there is no relation between the dermatoglyphic qualitative properties of alcoholic patients and those of the examinees from the comparison group. Despite the indisputable genetic role in the genesis of alcoholism, the analysis of the dermatoglyphics carried out in our study did not show any etiological connection between the results of the test on dermatoglyphics and the appearance of alcoholism.

    Full Text Available The purpose of this paper is to examine recent accounting rules to facilitate international harmonization in BRICS countries and to show how they have developed an accounting system that harmonizes with international standards, while maintaining macroeconomic control. This paper studies the influence of globalization on the development of accounting in BRICS countries, suggesting that the accounting practices of a country in harmony with international standards outlined above face barriers in the literature, such as the economic and accounting system - tradition. In order to answer the research question, the study primarily differences in contexts of international accounting and book-keeping from the BRICS countries subsequently in terms of the conceptual framework, clarifying thus the differences between the accounts of the BRICS and international Accounting and the causes of these differences.

    Full Text Available Objective: To use these growth charts to critically assess sufficiency of cases and parity of cases between residents, and to compare these growth charts to available international standards for minimum case numbers. Methods: Operative Log Growth Charts were developed for key indicator procedures for graduating otolaryngology residents in 2012-2014 at a large teaching hospital in the capital city of a newly industrialized country. Comparisons were made between years of training and required minimum case numbers published by the ACGME RRC for Otolaryngology. Results: Data was available to create 7 key indicator operative log growth charts to include all available data from 2012-2014 residents. These growth charts were used to assess growth in operative procedures for residents in the program compared to historical norms in the program. Graduating residents surpassed ACGME minimum case numbers in Bronchoscopy only and were below the minimum numbers for the other key indicators tested. Conclusion: There is significant heterogeneity in the standards for otolaryngology training between countries. It is possible to develop program-specific and country-specific operative log growth charts.

  10. Programming PHREEQC calculations with C++ and Python a comparative study

    Charlton, Scott R.; Parkhurst, David L.; Muller, Mike

    2011-01-01

    The new IPhreeqc module provides an application programming interface (API) to facilitate coupling of other codes with the U.S. Geological Survey geochemical model PHREEQC. Traditionally, loose coupling of PHREEQC with other applications required methods to create PHREEQC input files, start external PHREEQC processes, and process PHREEQC output files. IPhreeqc eliminates most of this effort by providing direct access to PHREEQC capabilities through a component object model (COM), a library, or a dynamically linked library (DLL). Input and calculations can be specified through internally programmed strings, and all data exchange between an application and the module can occur in computer memory. This study compares simulations programmed in C++ and Python that are tightly coupled with IPhreeqc modules to the traditional simulations that are loosely coupled to PHREEQC. The study compares performance, quantifies effort, and evaluates lines of code and the complexity of the design. The comparisons show that IPhreeqc offers a more powerful and simpler approach for incorporating PHREEQC calculations into transport models and other applications that need to perform PHREEQC calculations. The IPhreeqc module facilitates the design of coupled applications and significantly reduces run times. Even a moderate knowledge of one of the supported programming languages allows more efficient use of PHREEQC than the traditional loosely coupled approach.

  11. Comparing global alcohol and tobacco control efforts: network formation and evolution in international health governance.

    Smoking and drinking constitute two risk factors contributing to the rising burden of non-communicable diseases in low- and middle-income countries. Both issues have gained increased international attention, but tobacco control has made more sustained progress in terms of international and domestic policy commitments, resources dedicated to reducing harm, and reduction of tobacco use in many high-income countries. The research presented here offers insights into why risk factors with comparable levels of harm experience different trajectories of global attention. The analysis focuses particular attention on the role of dedicated global health networks composed of individuals and organizations producing research and engaging in advocacy on a given health problem. Variation in issue characteristics and the policy environment shape the opportunities and challenges of global health networks focused on reducing the burden of disease. What sets the tobacco case apart was the ability of tobacco control advocates to create and maintain a consensus on policy solutions, expand their reach in low- and middle-income countries and combine evidence-based research with advocacy reaching beyond the public health-centered focus of the core network. In contrast, a similar network in the alcohol case struggled with expanding its reach and has yet to overcome divisions based on competing problem definitions and solutions to alcohol harm. The tobacco control network evolved from a group of dedicated individuals to a global coalition of membership-based organizations, whereas the alcohol control network remains at the stage of a collection of dedicated and like-minded individuals.

    1995-01-01

    The establishment of the Framework Convention on Climate change has motivated a large number of mitigation costing studies of developing countries. A variety of modelling approaches and input assumptions have been employed, and studies have been carried out by a range of institutions, including international research institutions, consultants and national organisations. This paper attempts to bring together the main results and characteristics of some of the major recent studies. In spite of the diversity of teams involved in the studies, the similarities in scenario definitions and in the bottom-up approach used for the energy sector analysis, enable some key macro indicators and results of the studies to be compared. Two main coordinated country study efforts have been carried out: by the Lawrence Berkeley Laboratory (LBL) and by UNEP collaborating Centre on Energy and Environment (UCCEE). The results and methodological framework of these country studies are assessed in relation to similar country study activities for China, West Africa and South East Asia in order to evaluate possible common conclusions.

    This work aims to investigate the dose descriptor, volumetric Computed Tomography Dose Index (CTDI), a pediatric patients sample undergoing to skull CT, comparing the results with the diagnostic reference levels of the literature. Were collected volumetric CTDI values of all skull CT exams performed retrospectively in children of 0-10 years of age in a period of 12 months in a large hospital size. Patients, in a total of 103, were divided into four groups, where the criterion of separation used was age, trying to use the same division used in international references dose descriptors. In all acquisitions we used the pediatric protocol and the Automatic Exposure Control (AEC) available on the equipment. The CDTI values, with and without the use of AEC for pediatric studies, were compared. There was a reduction of approximately 100% in the absorbed dose value due to the use of the AEC. From the data collected and analyzed in this work, it is concluded that the use of dose reduction systems is relevant, such as the Care Dose, to maintain volumetric CTDI values within the reference levels. Also it is important the observation of range of children age to the appropriate choice of parameters used in the test protocol. The values obtained are according to the diagnostic reference levels from the literature

    ' interests, in that the turn-around time for assessments must be minimized, transparency must be maximized, the process must be considered fair using universally agreed standards and the process must be modifiable based on stakeholders' requirements; (ii) the assessment of medical technologies other than drugs may present different challenges and is managed separately in other HTA organizations; (iii) because of the link between HTA and reimbursement decisions, completion of the HTA process following regulatory approval can delay market access to new technologies, thus closer integration between regulatory approval and HTA processes is being explored internationally; (iv) there is a direct or indirect link to reimbursement in the jurisdictions explored - without this link the role of CER in the US will remain advisory; (v) each jurisdiction reviewed benefits from a single payer that is informed by the process - given the diverse multipayer environment in the US, CER in the US may usefully focus on generating comparative effectiveness evidence; (vi) a common metric for assessing intended and unintended effects of treatment allows comparison across different technologies; and (vii) one stated focus of CER is on therapeutic benefit among 'high-priority populations', including specific demographic groups (the elderly and children, racial and ethnic minorities) and individuals with disabilities, multiple chronic conditions and specific genomic factors. This will be difficult to achieve because epidemiological evidence of differences in therapeutic benefit among subgroups is detected through effect modification, or more specifically, statistical evidence of effect measure modification, typically on relative measures of effect. Few randomized trials have enough power to detect effect modification and these have been uncommon in the scientific literature. As consideration is given to the development of a publicly funded CER body in the US, much can be learned from the international

    This article addresses the vocabulary of cross-national analysis and commentary about health care, health policy and health politics. We conclude there is a large gap between promise and performance in comparative policy commentary and point to major sources of confusion, such as the lack of generally agreed vocabulary, vague language and the use of faddish and misleading terms and aspirational labels (illustrated by a selection of widely used expressions in comparative reports). We next examine the basic purposes of international policy comparison, distinguish three useful and two misleading approaches and frame defensible ground rules for comparative work.

  13. An International Ki67 Reproducibility Study

    Science.gov (United States)

    2013-01-01

    Background In breast cancer, immunohistochemical assessment of proliferation using the marker Ki67 has potential use in both research and clinical management. However, lack of consistency across laboratories has limited Ki67’s value. A working group was assembled to devise a strategy to harmonize Ki67 analysis and increase scoring concordance. Toward that goal, we conducted a Ki67 reproducibility study. Methods Eight laboratories received 100 breast cancer cases arranged into 1-mm core tissue microarrays—one set stained by the participating laboratory and one set stained by the central laboratory, both using antibody MIB-1. Each laboratory scored Ki67 as percentage of positively stained invasive tumor cells using its own method. Six laboratories repeated scoring of 50 locally stained cases on 3 different days. Sources of variation were analyzed using random effects models with log2-transformed measurements. Reproducibility was quantified by intraclass correlation coefficient (ICC), and the approximate two-sided 95% confidence intervals (CIs) for the true intraclass correlation coefficients in these experiments were provided. Results Intralaboratory reproducibility was high (ICC = 0.94; 95% CI = 0.93 to 0.97). Interlaboratory reproducibility was only moderate (central staining: ICC = 0.71, 95% CI = 0.47 to 0.78; local staining: ICC = 0.59, 95% CI = 0.37 to 0.68). Geometric mean of Ki67 values for each laboratory across the 100 cases ranged 7.1% to 23.9% with central staining and 6.1% to 30.1% with local staining. Factors contributing to interlaboratory discordance included tumor region selection, counting method, and subjective assessment of staining positivity.

    2013-06-01

    Full Text Available In recent years there have been changes in the foreign policy of Syria and Iran, showing how their goals are far from immutable. Typically they have been associated and in some circles they talk of an alliance. However, this paper aims to show that although there is a convergence in a number of issues, their foreign policy priorities put them away. For this, the text is divided into two parts. First, there is a comparison of the internal links that condition the foreign policy in each state. Secondly, regional (and global? projection of the two nations is contrasted. Throughout the document, the notion of James Rosenau´s comparative study of foreign policy will be taken as a reference.

  15. Varieties of glocalisation: the international economic strategies of Amsterdam, Manchester, and Zurich compared

    OpenAIRE

    Nico van der Heiden; Pieter Terhorst

    2007-01-01

    Our aim in this paper is to explain the international strategies of cities by focusing on market conditions. Drawing on a critique of the glocalisation thesis we show that the design of these strategies can plausibly be explained by the specific characteristics of urban capitalism found in the different cities. Whereas the international strategy of Manchester must be seen as a response to problems of postindustrial restrictions, the importance of the logistic sector in Dutch capitalism strong...

    2004-06-01

    This study aimed to evaluate the retention on two or four implants of eight resilient and nonresilient retentive anchors used in overdentures. Eight groups of retentive anchors were used: Dyna and Shiner (magnets); Dalla Bona and O-Ring (balls); Ceka Revax and Zaag attachments (studs); the cast bar (Dolder type) system with plastic clips; and the milled bars system. These specimens with their respective overdentures were prepared on two similar acrylic resin models with four implants (3.75 x 13 mm). Ten tensile strength tests (Instron) were performed on each group at a speed of 3 mm per minute. The statistical analysis (one-way analysis of variance, Tukey's HSD test) was considered significant. The pull force values ranged between 0.400 and 3.800 daN (International System of Units). There was a significant difference in retention in favor of the milled bars in comparison with the Ceka Revax, Hader bars, Zaag attachments, O-Ring, and Dyna groups, and a marginally significant difference compared with the Dalla Bona group. There was a highly significant difference with the Shiner magnets. The milled bar system was the most retentive anchor, with the Dalla Bona, Ceka Revax, Hader Bar, Zaag attachment, and O-Ring groups being the second most retentive. The least retentive groups were the Shiner and Dyna magnets. Proper abutment placement in the mandible and the correct selection of the retentive anchor will improve overdenture retention.

    The quality of the higher education is the result of a continuous process. There are many indicators that can be used to assess the quality of a higher education. The existence of different indicators makes the different result of university rankings. This research aims to find variables that can connect ranking indicators that are used by Indonesian Ministry of Research, Technology, and Higher Education with indicators that are used by international rankings by taking two kind of ranking systems i.e. Webometrics and 4icu. This research uses qualitative research method with comparative case studies approach. The result of the research shows that to bridge the indicators that are used by Indonesian Ministry or Research, Technology, and Higher Education with web-based ranking system like Webometrics and 4icu so that the Indonesian higher education institutions need to open access towards either scientific or non-scientific that are publicly used into web-based environment. One of the strategies that can be used to improve the openness and access towards scientific work of a university is by involving in open science and collaboration.

    2017-10-01

    Comfort in clothing is essential for user’s performance and is considered as a quality factor when choosing a particular piece of garment. Sportswear’s need include comfort and functionality, meaning that the thermo-physiological properties are of extreme importance. The aim of this work consists in comparing six different models of sports bra used specifically for running, taking into consideration the aspects of the thermo-physiological properties, air permeability, moisture behaviour, and friction. This paper is part of an ongoing research aiming to establish a comprehension about function and comfort characteristics for sport bras and propose a new bra with improved characteristics both in ergonomics design as well as in comfort performance. The thermal characterization of different regions on each bra were tested using Alambeta apparatus, Textest FX 3300 for air permeability and Frictorq for friction. Evaporation tests were also carried out in different regions on each bra at 37ºC corresponding to internal temperature of the human body. The results show that raw material, structures and construction can have influence in the properties studied.

  1. Comparative morphology of the axial complex and interdependence of internal organ systems in sea urchins (Echinodermata: Echinoidea

    Directory of Open Access Journals (Sweden)

    Ziegler Alexander

    2009-06-01

    Full Text Available Abstract Background The axial complex of echinoderms (Echinodermata is composed of various primary and secondary body cavities that interact with each other. In sea urchins (Echinoidea, structural differences of the axial complex in "regular" and irregular species have been observed, but the reasons underlying these differences are not fully understood. In addition, a better knowledge of axial complex diversity could not only be useful for phylogenetic inferences, but improve also an understanding of the function of this enigmatic structure. Results We therefore analyzed numerous species of almost all sea urchin orders by magnetic resonance imaging, dissection, histology, and transmission electron microscopy and compared the results with findings from published studies spanning almost two centuries. These combined analyses demonstrate that the axial complex is present in all sea urchin orders and has remained structurally conserved for a long time, at least in the "regular" species. Within the Irregularia, a considerable morphological variation of the axial complex can be observed with gradual changes in topography, size, and internal architecture. These modifications are related to the growing size of the gastric caecum as well as to the rearrangement of the morphology of the digestive tract as a whole. Conclusion The structurally most divergent axial complex can be observed in the highly derived Atelostomata in which the reorganization of the digestive tract is most pronounced. Our findings demonstrate a structural interdependence of various internal organs, including digestive tract, mesenteries, and the axial complex.

    2010-04-01

    Full Text Available Abstract Due to an increasing awareness of the potential hazardousness of air pollutants, new laws, rules and guidelines have recently been implemented globally. In this respect, numerous studies have addressed traffic-related exposure to particulate matter using stationary technology so far. By contrast, only few studies used the advanced technology of mobile exposure analysis. The Mobile Air Quality Study (MAQS addresses the issue of air pollutant exposure by combining advanced high-granularity spatial-temporal analysis with vehicle-mounted, person-mounted and roadside sensors. The MAQS-platform will be used by international collaborators in order 1 to assess air pollutant exposure in relation to road structure, 2 to assess air pollutant exposure in relation to traffic density, 3 to assess air pollutant exposure in relation to weather conditions, 4 to compare exposure within vehicles between front and back seat (children positions, and 5 to evaluate "traffic zone"-exposure in relation to non-"traffic zone"-exposure. Primarily, the MAQS-platform will focus on particulate matter. With the establishment of advanced mobile analysis tools, it is planed to extend the analysis to other pollutants including NO2, SO2, nanoparticles and ozone.

  6. Comparative evaluation of civil liability conventions on radioactive and oil pollution and liability under international law

    International Nuclear Information System (INIS)

    Hoche, A.

    1988-01-01

    In the event of transfrontier radioactive pollution or oil pollution, compensation for damage may be sought under two different liability systems: there is the framework of international law of liability of international persons, and there is the liability regime established by international conventions. The latter system has adopted a very friendly attitude towards the claims of a private victim claiming compensation from the private polluter. The book first sets out the basic principles and practice of the two liability systems, also considering the latest developments and current discussions advocating the acknowledgement of the principle of strict and absolute liability in international law. The relationship of the two systems is the major issue of the book, and the Chernobyl reactor accident has made it a particularly topical issue at that. The problems arising in the wake of this accident have shown the need for clarification in this field. The author suggests as a practical approach a strict separation of the two bases of claims, so that parallel or successive procedure on the level of international law or civil law is possible. Finally the problem of avoiding duplication in the payment of compensation is discussed. (orig./HP) [de

    International health care experiences offer undergraduate nursing students the opportunity for significant personal and professional growth. During a month-long travel course to Cameroon, West Africa, students improved their skills in clinical assessment, data management, intercultural communication, and collaboration based on an empowerment model of international partnership. Although it is not possible for all students to participate in providing health care in another country, it is possible to design a local course in which students are able to meet similar outcomes in a community health experience in partnership with an immigrant and refugee center.

    2010-01-01

    This study compared the ethnic identity and well-being of Korean Americans who were adopted internationally with immigrant/U.S.-born Korean Americans and Korean international students, as well as the relationship between ethnic identity and well-being for each group. One-hundred and seven college students completed measures of ethnic identity and subjective well-being. Immigrant/U.S.-born Korean Americans had higher ethnic identity scores than the other two groups. Immigrant/U.S.-born Korean Americans also had higher positive affect scores than international students. Ethnic identity was positively correlated with positive affect for all three groups (r's = .27 - .34), but was negatively correlated with negative affect for international students (r = -.44). Overall, the results suggest that ethnic identity, although slightly lower than non-adopted peers, is relevant to the well-being of adopted Korean American college students.

    2016-03-01

    A very large grey area exists between translational stem cell research and applications that comply with the ideals of randomised control trials and good laboratory and clinical practice and what is often referred to as snake-oil trade. We identify a discrepancy between international research and ethics regulation and the ways in which regulatory instruments in the stem cell field are developed in practice. We examine this discrepancy using the notion of 'national home-keeping', referring to the way governments articulate international standards and regulation with conflicting demands on local players at home. Identifying particular dimensions of regulatory tools - authority, permissions, space and acceleration - as crucial to national home-keeping in Asia, Europe and the USA, we show how local regulation works to enable development of the field, notwithstanding international (i.e. principally 'western') regulation. Triangulating regulation with empirical data and archival research between 2012 and 2015 has helped us to shed light on how countries and organisations adapt and resist internationally dominant regulation through the manipulation of regulatory tools (contingent upon country size, the state's ability to accumulate resources, healthcare demands, established traditions of scientific governance, and economic and scientific ambitions).

    2017-01-01

    Full Text Available Background/Aims: Open reduction and internal fixation (ORIF is a standard surgical procedure in jaw trauma and in orthognathic surgery. Insertion of screws is a significant risk for accidental tooth root injury with varying outcomes. Contrary evidences are found in literature due to a variety of study designs. This study was undertaken to address the lacunae and possibly estimate the difference in occurrence of tooth damage during or after ORIF between trauma and planned osteotomies. Materials and Methods: In this retrospective study, the data of ORIF in either trauma or orthognathic surgery fulfilling inclusion and exclusion criteria were collected and analyzed. Results: There were 1632 patients fulfilling the inclusion and exclusion criteria and formed the study group, of which 663 were in orthognathic surgery, of whom 210 had bimaxillary orthognathic surgery. In the trauma group, 358 patients had fractures involving both jaws whereas 272 had maxilla alone and 339 had mandibular fractures alone. On comparing the outcome, of the 9073 screws studied, 93.40% were not involved in any contact with the teeth, 6.3% were in category of potential hits (near apices or the root surfaces, and only 0.28% had evidence of root damage with the screws. It is observed that molar and premolar had a significant difference in terms of the type of surgery (P ≤ 0.05 whereas canine (P = 0.75 and incisor (P = 0.67 showed no statistical difference. Conclusion: ORIF when used as mentioned is a safe way for the management of fractures. The incidence of root injury is not uncommon but can be avoided with careful planning and execution.

    The aim of this study is to compare surgical outcomes of international medical graduates (IMGs) and United States medical graduates (USMGs). IMGs represent 15% of practicing surgeons in the United States (US), and their training pathways often differ substantially from USMGs. To date, differences in the clinical outcomes between the 2 cohorts have not been examined. Using a unique dataset linking AMA Physician Masterfile data with hospital discharge claims from Florida and New York (2008-2011), patients who underwent 1 of 32 general surgical operations were stratified by IMG and USMG surgeon status. Mortality, complications, and prolonged length of stay were compared between IMG and USMG surgeon status using optimal sparse network matching with balance. We identified 972,718 operations performed by 4581 surgeons (72% USMG, 28% IMG). IMG and USMG surgeons differed significantly in demographic (age, gender) and baseline training (years of training, university affiliation of training hospital) characteristics. USMG surgeons performed complex procedures (13.7% vs 11.1%, P educational background, surgical training characteristics, and practice patterns, IMG and USMG-surgeons deliver equivalent surgical care to the patients whom they treat.

    2007-01-01

    The markets of biomass for energy are developing rapidly and becoming more international. A remarkable increase in the use of biomass for energy needs parallel and positive development in several areas, and there will be plenty of challenges to overcome. The main objective of the study was to clarify the alternative future scenarios for the international biomass market until the year 2020, and based on the scenario process, to identify underlying steps needed towards the vital working and sustainable biomass market for energy purposes. Two scenario processes were conducted for this study. The first was carried out with a group of Finnish experts and the second involved an international group. A heuristic, semi structured approach, including the use of preliminary questionnaires as well as manual and computerised group support systems (GSS), was applied in the scenario processes. The scenario processes reinforced the picture of the future of international biomass and bioenergy markets as a complex and multi layer subject. The scenarios estimated that the biomass market will develop and grow rapidly as well as diversify in the future. The results of the scenario process also opened up new discussion and provided new information and collective views of experts for the purposes of policy makers. An overall view resulting from this scenario analysis are the enormous opportunities relating to the utilisation of biomass as a resource for global energy use in the coming decades. The scenario analysis shows the key issues in the field: global economic growth including the growing need for energy, environmental forces in the global evolution, possibilities of technological development to solve global problems, capabilities of the international community to find solutions for global issues and the complex interdependencies of all these driving forces. The results of the scenario processes provide a starting point for further research analysing the technological and commercial

    A method is described for producing molds which can be used in the construction of volumetric organ dosimeters. These negative organ molds are formed by wrapping quick-setting plaster bandages around a silicon-treated hardwood organ mold. The cast is cut in two and after further setting time is ready to contain the tissue equivalent materials and thermoluminescent powders. Such volumetric dosimeters will be useful for comparing experimental and calculated internal dosimetry results. (U.K.)

    Objective: To study the imaging appearance of experimental Parkinson's disease (PD) and to evaluate the different medical imaging exams on PD. Methods: CT, MRI, SPECT (dopamine transporter imaging and regional cerebral blood flow imaging, DAT imaging and rCBF imaging), and PET (glucose metabolism imaging) were performed on 8 monkeys before and after the infusion of MPTP into unilateral internal carotid artery to develop hemi-Parkinsonism models. Results: Hemi-Parkinsonism models were successfully induced on all 8 monkeys. On DAT imaging, the uptake values of the lesioned striatums decreased obviously after the MPTP treatment and were lower than that of the contralateral ones. The glucose metabolic rates of the lesioned striatums and thalamus in PD models were lower, compared to that of the healthy monkeys and that of the contralateral sides of themselves. Neither DAT nor glucose metabolism abnormalities was found on both the contralateral sides of the healthy and PD monkeys. On MRI images before MPTP treatment, only 4 of 8 PD models showed hypointense in bilateral globus pallidus. No abnormal MRI findings occurred in the first 2 months after injection of MPTP. At tile third month, hypointense appeared in globus pallidus of three monkeys. Enlarged hyposignal region in globus pallidus were found in three models. Of the above 6 monkeys, two appeared hypointense in putamina. Substantia nigra demonstrated no abnormalities before and after MPTP treatment. All rCBF and CT images were normal. Conclusion: The decreased density of DAT and decreased glucose metabolism on experimental PD can be showed early by DAT imaging and glucose metabolism imaging, MRI can show abnormal signal in the basal ganglia of PD but it is later than DAT and glucose metabolism imaging. CT and rCBF find no abnormality on PD

It argues that those contextual elements and/or process characteristics that are mostly ignored by a case-study approach (for being more or less invisible and/or for being more or less self-evident might come to the fore through a comparative approach. Simultaneously, the particular nature of single rural development processes might equally be specified through systematically organized comparisons. In this way, current rural development processes are characterized as a set of responses to market failures - a set of responses that requires and involves the active construction of new, nested markets.

    Abstract Background Patients who have severe narrowing at or near the origin of the internal carotid artery as a result of atherosclerosis have a high risk of ischaemic stroke ipsilateral to the arterial lesion. Previous trials have shown that carotid endarterectomy improves long-term outcomes, particularly when performed soon after a prior transient ischaemic attack or mild ischaemic stroke. However, complications may occur during or soon after surgery, the most serious of which is stroke, w...

    The International Classification of Functioning children and youth version (ICF-CY) provides a universal framework for defining and classifying functioning and disability in children worldwide. To facilitate the application of the ICF in practice, ICF based-tools like the "ICF Core Sets" are being developed. In the context of the development of the ICF-CY Core Sets for children with Cerebral Palsy (CP), the aims of this study were as follows: to identify and compare the content of outcome measures used in studies of children with CP using the ICF-CY coding system; and to describe the most frequently addressed areas of functioning in those studies. We searched multiple databases likely to capture studies involving children with CP from January 1998 to March 2012. We included all English language articles that studied children aged 2-18 years and described an interventional or observational study. Constructs of the outcome measures identified in studies were linked to the ICF-CY by two trained professionals. We found 231 articles that described 238 outcome measures. The outcome measures contained 2193 concepts that were linked to the ICF-CY and covered 161 independent ICF-CY categories. Out of the 161 categories, 53 (33.5%) were related to body functions, 75 (46%) were related to activities/participation, 26 (16.1%) were related to environmental factors, and 7 (4.3%) were related to body structures. This systematic review provides information about content of measures that may guide researchers and clinicians in their selection of an outcome measure for use in a study and/or clinical practice with children with CP.

    Pipe bends or elbows are commonly used components for nuclear power plant piping system. In service, these piping components are subjected to internal pressure in addition to bending loads and the internal pressure is known to have a significant effect on the load carrying capacity of these components. Hence, a systematic study was carried out to investigate and quantify the effect of internal pressure on the fracture behaviour of elbows used in nuclear power plant piping system. Fracture studies were conducted on five 219 mm diameter carbon steel elbows with and without internal pressure under in-plane opening moment. The investigations have shown that the presence of a circumferential notch at the intrados has a more detrimental effect on the fracture behaviour of the elbow, when compared with the presence of an axial notch at the intrados. It is also found that internal pressure plays a significant role in reducing the ovalization. -- Highlights: • Fracture studies were conducted on elbows with and without internal pressure. • Effect of internal pressure on load carrying capacity of the elbows was studied. • Various data acquired during the study include load, LLD, CMOD, ovality of the elbow. • Circumferential notch at intrados significantly affects elbow load carrying capacity

    Full Text Available There is little evidence about linguistic expressions used that show internalized homophobia by homosexual individuals. The objective of this research was to explore suggestive internalized homophobic language used by web page users for homosocialization purposes among homosexual men living in Bogotá and Cartagena, Colombia. A qualitative study was designed with the purpose of analyzing content of 40 profiles, 20 from Bogota, and in the same proportion in Cartagena. This was based on account profiles from a website which contained contact inquiries between people who were not heterosexual and described homophobic characteristics when referring to their ideal partner. It was observed that in 19 out of 20 profiles in Bogotá and the same proportion in Cartagena people used suggestive and direct qualifiers that showed internalized explicit homophobia and implicit language, for instance, “I am looking for serious people”. The internalized homophobia is expressed by looking for that “macho” man who is professional and lives a heterosexual lifestyle. Authors conclude that homosexual men who requested contact with other men by Internet often expressed internalized homophobia in explicit and implicit ways, which suggests accepting hegemonic model of masculine men. Quantitative studies are needed in Colombian non-heterosexual populations.

  16. Stormwater management criteria for on-site pollution control: a comparative assessment of international practices.

    Over the last decade, a growing interest has been shown toward innovative stormwater management practices, breaking away from conventional "end of pipe" approaches (based on conveying water offsite to centralized detention facilities). Innovative strategies, referred to as sustainable urban drainage systems, low impact development (LID) or green infrastructures, advocating for management of runoff as close to its origin as possible, have therefore gained a lot of popularity among practitioners and public authorities. However, while the need for pollution control is generally well accepted, there is no wide agreement about management criteria to be given to developers. This article hence aims to compare these criteria through literature analysis of different state or local stormwater management manuals or guidelines, investigating both their suitability for pollution control and their influence on best management practices selection and design. Four categories of criteria were identified: flow-rate limitations, "water quality volumes" (to be treated), volume reduction (through infiltration or evapotranspiration), and non-hydrologic criteria (such as loads reduction targets or maximum effluent concentrations). This study suggests that hydrologic criteria based on volume reduction (rather than treatment) might generally be preferable for on-site control of diffuse stormwater pollution. Nonetheless, determination of an appropriate management approach for a specific site is generally not straightforward and presents a variety of challenges for site designers seeking to satisfy local requirements in addressing stormwater quantity and quality issues. The adoption of efficient LID solution may therefore strongly depend on the guidance given to practitioners to account for these management criteria.

    The International Cancer Benchmarking Partnership (ICBP) identified significant international differences in lung cancer survival. Differing levels of comorbid disease across ICBP countries has been suggested as a potential explanation of this variation but, to date, no studies have quantified its impact. This study investigated whether comparable, robust comorbidity scores can be derived from the different routine population-based cancer data sets available in the ICBP jurisdictions and, if so, use them to quantify international variation in comorbidity and determine its influence on outcome. Linked population-based lung cancer registry and hospital discharge data sets were acquired from nine ICBP jurisdictions in Australia, Canada, Norway and the UK providing a study population of 233 981 individuals. For each person in this cohort Charlson, Elixhauser and inpatient bed day Comorbidity Scores were derived relating to the 4-36 months prior to their lung cancer diagnosis. The scores were then compared to assess their validity and feasibility of use in international survival comparisons. It was feasible to generate the three comorbidity scores for each jurisdiction, which were found to have good content, face and concurrent validity. Predictive validity was limited and there was evidence that the reliability was questionable. The results presented here indicate that interjurisdictional comparability of recorded comorbidity was limited due to probable differences in coding and hospital admission practices in each area. Before the contribution of comorbidity on international differences in cancer survival can be investigated an internationally harmonised comorbidity index is required. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

    Full Text Available Background: HIV (Human immunodeficiency Virus, AIDS and cancer are feared terminal diseases. HIV sufferers are known to be stigmatized. The stigma surrounding cancer, unfortunately, is hardly the focus of psychological investigations, and hence this provoked the need to compare the stigma suffered by both groups, and how these have impacted on the psychological functioning of the disease sufferer. Objectives: The study had two main objectives, firstly, to explore whether HIV patients suffer more stigma than cancer patients or not, and secondly, to understand the most common type of stigma and if stigma is associated with psychopathology. Psychopathology is measured with GHQ–28 which evaluates somatic complaints, anxiety, depression and social dysfunction. Method: The study was a survey, and descriptive in nature, and anchored on two hypotheses: Firstly, that HIV patients will experience more stigmas than cancer patients and consequently report more psychological dysfunctions. Secondly that there will be a significant difference between types of stigma and the symptoms reported about them. Data were collected from a conveniently sampled group of 50 HIV positive patients and another 50 patients diagnosed with cancer, in two clinics and a hospital around the Gauteng Province. The majority of the participants were females, numbering 62 (62, 0%, whilst 38 (38.0% were males. The age of the respondents ranged from 20–73 years with a mean age of 44.4 years (s.d. = 11.6. Results: Results revealed a significant main effect for enacted stigma F = (1.98, = 17.629, p < .001 and anxiety F = (1.98 = 5.750, p < .001. A post hoc Bonferroni also showed that HIV patients had a higher mean score of enacted stigma (X-bar = 4.22 than cancer patients (X-bar = 1.28 and also HIV patients reported more anxiety (X-bar = 8.81 than cancer patients (X-bar = 6.42. Enacted stigma significantly influenced the GHQ Total (F = (98 = 1.700, p < .05; anxiety (F = (97 = 2.578, p
