  1. Assessment of the factors with significant influence on safety culture

    International Nuclear Information System (INIS)

    In this paper, a qualitative and a quantitative evaluation of the factors with significant impact on safety culture were performed. These techniques were established and applied in accordance with IAEA standards. In order to show the applicability and opportunity of the methodology a specific case study was prepared: safety culture evaluation for INR Pitesti. The qualitative evaluation was performed using specific developed questionnaires. Through analysis of the completed questionnaires was established the development stage of safety culture at INR. The quantitative evaluation was performed using a guide to rate the influence factors. For each factor was identified the influence (negative or positive) and ranking score was estimated using scoring criteria. The results have emphasized safety culture stages. The paper demonstrates the fact that using both quantitative and qualitative assessment techniques, a practical value of the safety culture concept is given. (authors)

    Reducing medical error is critical to improving the safety and quality of healthcare. Physician stress, fatigue, and excessive workload are performance-shaping factors (PSFs) that may influence medical events (actual administration errors and near misses), but direct relationships between these factors and patient safety have not been clearly defined. This study assessed the real-time influence of emotional stress, workload, and sleep deprivation on self-reported medication events by physicians in academic hospitals. During an 18-month study period, 185 physician participants working at four university-affiliated teaching hospitals reported medication events using a confidential reporting application on handheld computers. Emotional stress scores, perceived workload, patient case volume, clinical experience, total sleep, and demographic variables were also captured via the handheld computers. Medication event reports (n = 11) were then correlated with these demographic and PSFs. Medication events were associated with 36.1% higher perceived workload (p sleep (p = .10). These results confirm the effect of factors influencing medication events, and support attention to both provider and hospital environmental characteristics for improving patient safety.

    Full Text Available BACKGROUND: We examined the relationship between morale measured by the Philadelphia Geriatric Morale Scale (PGC and disability, social support, religiosity, and personality traits. Instruments predicting morale were then tested against PGC domains. METHODS: The study utilized a cross-sectional survey with a multistage cluster sampling design. Instruments used were disability (disease burden; WHO Disability Score-II, WHODAS-II, social support (Duke Social Support Scale, DUSOCS; Lubben Social Network Scale, LSNS-6; Medical Outcomes Study Social Support Survey, MOS-SSS, religiosity (Revised Intrinsic-Extrinsic Religious Orientation Scale, I/E-R, and personality (Ten-Item Personality Inventory, TIPI. These were plotted as bar charts against PGC, resolved with one-way ANOVA and Kruskal-Wallis tests, then corrected for multiple comparisons. This process was repeated with PGC domains. Contribution of factors was modeled using population attributable risk (PAR and odds ratios. Effect of confounders such as gender, age, and ethnicity were checked using binary logistic regression. RESULTS: All instruments showed clear relationships with PGC, with WHODAS-II and DUSOCS performing well (ANOVA p<0.001. For PGC domains, attitude toward aging and lonely dissatisfaction trended together, while agitation did not. PAR, odds ratios, and Exp(β were disability (WHODAS-II: 28.5%, 3.8, 2.8, social support (DUSOCS: 28.0%, 3.4, 2.2, religiosity (I/E-R: 21.6%, 3.2, 2.1, and personality (TIPI: 27.9%, 3.6, 2.4. Combined PAR was 70.9%. CONCLUSIONS: Disability, social support, religiosity, and personality strongly influence morale in the elderly. WHODAS-II and DUSOCS perform best in measuring disability and social support respectively.

    Full Text Available The pollen beetle, Meligethes aeneus F. (Coleoptera: Nitidulidae, is a severe pest of winter oilseed rape. A phenological model to forecast the first spring invasion of crops in Luxembourg by M. aeneus was developed in order to provide a tool for improving pest management and for assessing the potential effects of climate change on this pest. The model was derived using long-term, multi-site observational datasets of pollen beetle migration and meteorological data, as the timing of crop invasion is determined mainly by meteorological variables. Daily values of mean air and soil temperature, accumulated sunshine duration and precipitation were used to create a threshold-based model to forecast crop invasion. Minimising of the root mean squared error (RMSE of predicted versus observed migration dates was used as the quality criterion for selecting the optimum combination of threshold values for meteorological variables. We identified mean air temperature 8.0 °C, mean soil temperature 4.6 °C, and sunshine duration of 3.4 h as the best threshold values, with a cut-off of 1 mm precipitation and with no need for persistence of those conditions for more than one day (RMSE=9.3days$RMSE=9.3\\,\\text{days}$. Only in six out of 30 cases, differences between observed and predicted immigration dates were >5$>5$ days. In the future, crop invasion by pollen beetles will probably be strongly affected by changes in air temperature and precipitation related to climate change. We used a multi-model ensemble of 15 regional climate models driven by the A1B emission scenario to assess meteorological changes in two 30‑year future periods, near future (2021–2050 and far future (2069–2098 in comparison with the reference period (1971–2000. Air temperature and precipitation were predicted to increase in the first three months of each year, both in the near future and the far future. The pollen beetle migration model indicated that this change would

    While rare, complications do occur with the esthetic use of dermal fillers. Careful attention to patient factors and technique can do much to avoid these complications, and a well-informed practitioner can mitigate problems when they do occur. Since cosmetic surgery is usually an elective process, requested by the patient, clinical trials are complex to organize and run. For this reason, an international group of practicing physicians in the field of esthetics came together to share knowledge and to try and produce some informed guidance for their colleagues, considering the literature and also pooling their own extensive clinical experience. This manuscript aims to summarize the crucial aspects of patient selection, including absolute contraindications as well as situations that warrant caution, and also covers important considerations for the pre- and posttreatment periods as well as during the procedure itself. Guidance is given on both immediate and long-term management of adverse reactions. The majority of complications are related to accepting patients inappropriate for treatment or issues of sterility, placement, volume, and injection technique. It is clear that esthetic practitioners need an in-depth knowledge of all aspects of treatment with dermal fillers to achieve optimal outcomes for their patients. PMID:25926750

    Full Text Available Abstract Background Evaluating the impact of recommendations based upon health technology assessment (HTA represents a challenge for both HTA agencies and healthcare policy-makers. Using a psychosocial theoretical framework, this study aimed at exploring the factors affecting physician intention to adopt HTA recommendations. The selected recommendations were prioritisation systems for patients on waiting lists for two surgical procedures: hip and knee replacement and cataract surgery. Methods Determinants of physician intention to use HTA recommendations for patient prioritisation were assessed by a questionnaire based upon the Theory of Interpersonal Behaviour. A total of 96 physicians from two medical specialties (ophthalmology and orthopaedic surgery responded to the questionnaire (response rate 44.2%. A multiple analysis of variance (MANOVA was performed to assess differences between medical specialties on the set of theoretical variables. Given the main effect difference between specialties, two regression models were tested separately to assess the psychosocial determinants of physician intention to use HTA recommendations for the prioritisation of patients on waiting lists for surgical procedures. Results Factors influencing physician intention to use HTA recommendations differ between groups of specialists. Intention to use the prioritisation system for patients on waiting lists for cataract surgery among ophthalmologists was related to attitude towards the behaviour, social norms, as well as personal normative beliefs. Intention to use HTA recommendations for patient prioritisation for hip and knee replacement among orthopaedic surgeons was explained by: perception of conditions that facilitated the realisation of the behaviour, personal normative beliefs, and habit of using HTA recommendations in clinical work. Conclusion This study offers a model to assess factors influencing the intention to adopt recommendations from health

  12. Assessing the influence of human factors and experience on Predator mishaps

    Science.gov (United States)

    Herz, Robert P.

    This applied dissertation was designed to assess the influence of human factors and experience on Predator mishaps as measured by unsafe acts and the frequency and cost of mishaps. The use of unmanned air vehicles (UAVs) in military operations is expanding rapidly, and this trend will likely continue given increases in funding for UAV development from 3 billion in the 1990s to over 12 billion for 2004-2009. High UAV mishap numbers have generated multiple reviews of unmanned operations in the past few years, but even within common platforms, different analysts attributed these mishaps to differing causes. Sixty-four Air Force Predator Class A, B, C mishaps occurred from the introduction of this system into the operational Air Force inventory in 1997 through the end of fiscal year 2006. Reports were reviewed to identify trends. Substantial changes over time were observed regarding annual mishap rates, annual mishap counts, causal factors and impacts due to experience levels. Mishap rates across the past three years dropped to less than one-half the rate across earlier years. Mishap counts, however, steadily increased, as did Predator flying hours. Early mishap reports typically cited mechanical problems and operator station design issues. Mechanical problems were much less frequently cited in the last three years. Rather, 80% of recent mishaps cited causal human error factors. Equipment interface problems were still cited as causal or major contributing factors in almost half of recent mishaps. Recent mishap reports often cited shortfalls in human factors attributes including skill and knowledge to include checklist error, task prioritization, lack of training for task attempted, and inadequate system knowledge, situational awareness focused on channelized attention, and crew coordination. These trends come in a period characterized by a rapidly growing crew force and highlight the need to revisit both individual and team Predator training objectives and consider

    To compare and assess factors influencing the detection of an inflamed appendix by both ultrasonography (US) and CT. We retrospectively analyzed US and CT findings of 58 patients with confirmed acute appendicitis (42 patients with perforation and 16 patients without perforation), in which both preoperative US and CT scans were performed. We compared the use of US and CT for the diagnostic accuracy of acute appendicitis, and determined the detection rate for an inflamed appendix. According to the location of the appendix, the amount of mesenteric fat content in lower abdominal cavity, the presence of cecal wall thickening, and the presence of pericecal fluid or an abscess, the use of US and CT were compared for the determination of the detection rate of an inflamed appendix. The diagnostic accuracies for US and CT for acute appendicitis in our study group were both 93.1%, and there was no difference between the use of the two modalities. Although the detection rate of an inflamed appendix was slightly higher for US (93.1%) than for CT (84.5%), the difference between the use of the two modalities was not significant (p > 0.05). There was no significant difference in the detection rate of an inflamed appendix between the use of US and CT according to location of appendix, the amount of mesenteric fat content and the presence of cecal wall thickening. A pelvic location of the inflamed appendix and the presence of pericecal fluid or an abscess, were factors that significantly increased the detection rate for US than for CT (p < 0.05). The use of US for diagnosis of acute appendicitis is as useful as the use of CT. US is especially useful to detect an inflamed appendix more effectively than CT in cases where the appendix is in a pelvic location and presents with pericecal fluid or an abscess

    Full Text Available The goal of the article lies in building a complex scorecard used for assessment of influence of socio-economic factors of enterprise development. The article specifies such groups of socio-economic factors as factors of organisational and managerial impact; workers potential and their professional development; social protection of workers; labour protection and healthcare; and social infrastructure. Having analysed and compared concepts and approaches to assessment of enterprise activity, the article identifies that insufficient attention is paid to socio-economic indicators. That is why a scorecard is developed in the context of the said groups of factors, which gives a possibility to identify weaknesses in enterprise development and to direct measures on their elimination or minimisation on the basis of it. The proposed scorecard of assessment of socio-economic factors of enterprise development gives a possibility to, objectively and timely, monitor the socio-economic state of an enterprise, which allows maintaining the development trajectory.

    One in four Canadian adults is obese, and more women are entering pregnancy with a higher body mass index (BMI) than in the past. Pregnant women who are overweight or obese have a higher risk of pregnancy-related complications than women of normal weight. Gestational weight gain (GWG) is also associated with childhood obesity. Although the factors influencing weight gain during pregnancy are multifaceted, little is known about the social inequality of GWG. This review will address some of the socioeconomic factors and maternal characteristics influencing weight gain and the impact that excessive GWG has on health outcomes such as post-partum weight retention. The effects of an overweight or obese pre-pregnancy BMI on GWG and neonatal outcomes will also be addressed. The timing of weight gain is also important, as recommendations now include trimester-specific guidelines. While not conclusive, preliminary evidence suggests that excessive weight gain during the first trimester is most detrimental. PMID:26742688

  20. How to Assess Performance in Cycling: the Multivariate Nature of Influencing Factors and Related Indicators.

    Directory of Open Access Journals (Sweden)

    2013-05-01

    Full Text Available Finding an optimum for the cycling performance is not a trivial matter, since the literature shows the presence of many controversial aspects. In order to quantify different levels of performance, several indexes have been defined and used in many studies, reflecting variations in physiological and biomechanical factors. In particular, indexes such as Gross Efficiency (GE, Net Efficiency (NE and Delta Efficiency (DE have been referred to changes in metabolic efficiency (EffMet, while the Indexes of Effectiveness (IE, defined over the complete crank revolution or over part of it, have been referred to variations in mechanical effectiveness (EffMech. All these indicators quantify the variations of different factors (i.e. muscle fibers type distribution, pedaling cadence, setup of the bicycle frame, muscular fatigue, environmental variables, ergogenic aids, psychological traits, which, moreover, show high mutual correlation. In the attempt of assessing cycling performance, most studies in the literature keep all these factors separated. This may bring to misleading results, leaving unanswered the question of how to improve cycling performance. This work provides an overview on the studies involving indexes and factors usually related to performance monitoring and assessment in cycling. In particular, in order to clarify all those aspects, the mutual interactions among these factors are highlighted, in view of a global performance assessment. Moreover, a proposal is presented advocating for a model-based approach that considers all factors mentioned in the survey, including the mutual interaction effects, for the definition of an objective function E representing the overall effectiveness of a training program in terms of both metabolic efficiency and mechanical effectiveness.

    International Nuclear Information System (INIS)

    Elastomeric seals offer considerable advantages in the achievement of high integrity sealing. This report discusses the factors limiting the performance of elastomers under fault conditions, with particular attention to Nuclear Fuel Transport Flask seals. There is emphasis on seal compression and its optimisation, so that it is high enough to ensure adequate surface roughness infilling, and low enough to avoid damaging tensile stresses. The assessment of seal performance is discussed, and includes consideration of pressure actuation and extrusion, permeation losses and rig testing. It is concluded that to reach a satisfactory design requires considerable information on different aspects of elastomeric performance. (author)

    International Nuclear Information System (INIS)

    Aim: To compare cosmetic results of different radiotherapy schedules used in the treatment of breast cancer after breast radiotherapy and to identify factors affecting cosmetic outcomes. Material and methods: Ninety-four patients irradiated. Median follow-up of 29 months (range 18-154 mo.). Patients were treated with standard fractionation 45-50 Gy/20-25 fx/4-5 weeks. Boost up to 10 Gy. Late effects were evaluated using the LENT-SOMA scoring scale. The cosmetic results were assessed on a four-point scale and presence of concomitant chemotherapy. Results: LENT-SOMA grade 3 toxicity was observed only in 8 (8,5%) patients. The factor associated with hyperpigmentation is large breast size. The significant risk factors for teleangiectasia are high dose and use photon energy 1,33 MeV beam. Factors found to impact significantly cosmetics adversely fibrosis was large breast size. Breast fibrosis were more frequent observed in woman after whole dose 50 Gy. There were no differences in breast skin thick between analysed factors. Conclusions: After irradiating large breasts more often than one observes the fibrosis of the breast in the case of small and average breasts and discolour of the skin. Irradiating photons from the cobalt source in the comparison with photons about higher energy at women with large breasts, there is the reason more frequent occurrence of the skin angioma. For the final cosmetic effect of radiotherapy in saving treatment, they do not have the impact: tumor size, boost method, chemical treatment, patients age. (authors)

    Full Text Available Salt steppes and marshes represent the most valuable ecosystems in the world, providing numerous ecosystem services that are extremely vulnerable to anthropogenic influences. These types of habitat in the territory of Serbia are most dominant in Banat and a significant portion of them is under protection or in the process of becoming protected. The section surrounding the protected areas of Slano Kopovo Special Nature Reserve, Rusanda Nature Park and Okanj Bara Special Nature Reserve with the non-building area of Novi Bečej, Kumane, Melenci, Elemir and Taraš cadastral municipalities, has been chosen for the analysis. The aim of this paper was to assess the influence of specific anthropogenic factors on the elements of an ecological network using the analytical method that can generate the required results in a manner suitable for presentation to various stakeholders. To achieve this aim, the Leopold matrix model, used for assessing anthropogenic influence on the environment, has been chosen. The specificity of this issue of protecting and preserving elements of an ecological network resulted in the need to isolate and evaluate the factors affecting the preservation of habitats and functionality of ecosystems, unlike the concept of Leopold matrix, which treats all factors as equally important in the process of evaluation. Evaluation results indicate significant effects of historical, perennial manner of using the area and other resources in the non-building area.

  9. A dynamic business - Price and technical developments are the factors that influence the assessment of gas reserves

    International Nuclear Information System (INIS)

    This article investigates the situation concerning the assessment of natural gas reserves, which can vary considerably. The factors that influence the assessment are discussed, including the market situation, current demand and the global political situation. The situation in various regions and countries is discussed, including situations in oil-producing areas where gas is often burnt off since neither distribution networks nor local consumers are available. Also, the problem of whether 'unconventional' reserves are to be included in assessments or not is discussed, particularly in connection with their low level of predictability. The various 'unconventional' sources such as methane hydrates and deep-lying natural gas reserves are discussed as is the production of methane from biogenic resources using fermentation techniques. Developments in the exploration area are discussed that allow expensive drilling operations to achieve a better degree of success, as is progress in drilling technology itself, which is allowing existing gas fields to be better exploited

    Joint destruction in early adulthood brings the patients to the orthopaedic clinics. If a haemophilic patient becomes disabled, it shows a number of factors such as timely diagnosis, availability of appropriate treatment depending on the country, access and affordability to treatments and equally importantly the responsibility of the patient in managing self care by remaining compliant by prescribed treatment regimen. We assessed the functional level by functional independence score in haemophilia (FISH). Overall, 104 patients with haemophilia A and 29 with haemophilia B were evaluated. We assessed the function of the patients by FISH. We divided the sum scores into weak (FISH score 8-16), moderate (17-24), and good (25-32). For evaluating the level of functional deficit in a 2 × 2 table, we categorized the weak and moderate levels into Disordered Group and the good level into Not-Disordered Group. The average age was 26.9 ± 14.24. Each 1 year increase in age can increase 1.07 fold the possibility of being placed in Disordered Function Group. Severe haemophilia can increase 7.34 fold, presence of inhibitor can increase 9.75 fold and home self-care increases 3.89 fold the possibility of being placed in Disordered Function Group. To decrease the burden of the cost on patient, family and the government, education plays the most important role. We suggest that we send a trained team of physician and nurses to the deprived villages and cities instead of waiting for the patient to refer to our Care Center. PMID:24118441

    Full Text Available Abstract Background The ‘Doctors to the Barrios’ (DTTB Program was launched in 1993 in response to the shortage of doctors in remote communities in the Philippines. While the Program has attracted physicians to work in such areas for the prescribed 2-year period, ongoing monitoring shows that very few chose to remain there for longer and be absorbed by their Local Government Unit (LGU. This assessment was carried out to explore the reasons for the low retention rates and to propose possible strategies to reverse the trend. Methods A mixed methods approach was used comprising a self-administered questionnaire for members of the current cohort of DTTBs, and oral interviews with former DTTBs. Results Among former DTTBs, the wish to serve rural populations was the most widely cited motivation. By comparison, among the current cohort of DTTBs, more than half joined the Program due to return of service obligations; a quarter to help rural populations, and some out of an interest in public health. Those who joined the Program to return service experienced significantly less satisfaction, whilst those who joined out of an interest in public health were significantly more satisfied with their rural work. Those who graduated from medical schools in the National Capital Region were significantly more critical about their compensation and perceived there to be fewer options for leisure in rural areas. With regard to the factors impeding retention, lack of support from the LGU was most frequently mentioned, followed by concerns about changes in compensation upon absorption by the LGU, family issues and career advancement. Conclusions Through improved collaboration with the Department of Health, LGUs need to strengthen the support provided to DTTBs. Priority could be given to those acting out of a desire to help rural populations or having an interest in public health, and those who have trained outside of the National Capital Region.

    Full Text Available OBJECTIVE: To analyze parameters of respiratory system mechanics and oxygenation and cardiovascular alterations involved in weaning tracheostomized patients from long-term mechanical ventilation after cardiac surgery. METHODS: We studied 45 patients in their postoperative period of cardiac surgery, who required long-term mechanical ventilation for more than 10 days and had to undergo tracheostomy due to unsuccessful weaning from mechanical ventilation. The parameters of respiratory system mechanics, oxigenation and the following factors were analyzed: type of surgical procedure, presence of cardiac dysfunction, time of extracorporeal circulation, and presence of neurologic lesions. RESULTS: Of the 45 patients studied, successful weaning from mechanical ventilation was achieved in 22 patients, while the procedure was unsuccessful in 23 patients. No statistically significant difference was observed between the groups in regard to static pulmonary compliance (p=0.23, airway resistance (p=0.21, and the dead space/tidal volume ratio (p=0.54. No difference was also observed in regard to the variables PaO2/FiO2 ratio (p=0.86, rapid and superficial respiration index (p=0.48, and carbon dioxide arterial pressure (p=0.86. Cardiac dysfunction and time of extracorporeal circulation showed a significant difference. CONCLUSION: Data on respiratory system mechanics and oxygenation were not parameters for assessing the success or failure. Cardiac dysfunction and time of cardiopulmonary bypass, however, significantly interfered with the success in weaning patients from mechanical ventilation.

  14. Influence of region and site-specific factors on the degree of general validity of ecological and primary-energy-related assessments of biogas

    International Nuclear Information System (INIS)

    As described in this publication, since the early 1990s numerous studies based on the life cycle assessment methodology have been dedicated to assessments of different kinds of bioenergy in comparison with fossil energy resources in terms of their energy balance and environmental impact. On reviewing the results of these studies one finds a strikingly wide range of variation. One major factor of influence on the results of life cycle assessments, besides methodological factors such as the choice of allocation method, is the representativeness of the data used. Thus, widely varying results are also obtained when balance calculations and assessments are performed on energy crops with due consideration to regional and site-specific factors. To address this problem the present study endeavoured to identify region and site-specific factors and assess them in terms of their influence on the life cycle assessment of the cultivation and conversion to biogas of different kinds of energy crops. For this purpose the following questions were explored: What influence do region, site and equipment-specific factors have on the results of ecological and primary-energy-related assessments; and how large are the differences in results between region and site-specific assessments on the one hand and assessments based on general assumptions on the other? It transpires that the results of region and site-specific assessments differ from one another in terms of both the assessment of energy cropping and the assessment of the entire process chain of biogas production and conversion to electricity.

    Environmental factors may influence types and contents of active substances. This study investigated the influence of environmental factors on the active substance contents and antioxidant activity of Potentilla fruticosa L. from different regions of China. Also, HPLC fingerprint similarity analysis (SA) coupled with hierarchical cluster analysis (HCA) and discriminant analysis (DA) were further introduced for the accurate classification and quality assessment of P. fruticosa. The results showed that altitude was significantly and negatively correlated to the content of tannin (P < 0.05). Annual sunshine duration and altitude were significantly and positively correlated to the flavonoids content, rutin content and antioxidant activity (P < 0.05). Annual mean temperature was significantly and negatively correlated to the content of total phenolics, while altitude was significantly and positively correlated to the content of total phenolics (P < 0.05). Eight samples were unambiguously separated into three groups. Two types of discriminant functions with a 100% discrimination ratio were constructed. All data consistently supported the conclusion that P. fruticosa produced from Kangding, Sichuan Province had high quality among all samples, therefore, Kangding in Sichuan Province with favorable environmental conditions is recommended as a preferable production location.

    The Henry's Law constant ( k) for phosphine in seawater was determined by multiple phase equilibration combined with headspace gas chromatography. The effects of pH, temperature, and salinity on k were studied. The k value for phosphine in natural seawater was 6.415 at room temperature (approximately 23°C). This value increases with increases in temperature and salinity, but no obvious change was observed at different pH levels. At the same temperature, there was no significant difference between the k for phosphine in natural seawater and that in artificial seawater. This implies that temperature and salinity are major determining factors for k in marine environment. Double linear regression with Henry's Law constants for phosphine as a function of temperature and salinity confirmed our observations. These results provide a basis for the measurement of trace phosphine concentrations in seawater, and will be helpful for future research on the status of phosphine in the oceanic biogeochemical cycle of phosphorus.

Tradition is no longer a factor which determines the decision whether or not to have a baby. A prognosis of the Polish Central Statistical Office (GUS shows that the population of Poland will fall from 38 to 36 million by 2035. The aim of this study is to assess the procreation behaviour of women in Greater Poland Region. materials and methods. For the research purpose, 3,120 women of reproductive age were examined by using an author designed questionnaire and a synthetic Family Financial Standard Index. results: 74.6% of the respondents lived in an urban area, 25.4% of women come from a rural area. 49% of examined women did not want to have a bigger family, 45% would like to have another child. Analysis of the reasons why women did not want to have another baby revealed that predominance of the financial factor – 67%, living conditions – 18.4% and health– 13.2%. Only 11.9% of the women declared their high financial status, 4.8% of families received family allowance from the government; 88.4% of the examined families did not receive any social benefits. Bad housing situation was declared by 5% of the respondents, 26.7% of the interviewees lived with family members, i.e. parents or grandparents. Analysis of the data concerning religious bonds showed that 67.6% of women declared their indifference to religion. conclusions. The economic factor was an important reason limiting procreation. The bad situation on the real estate market combined with an insufficient range of social welfare led to a decrease in the birth-rate in the Greater Poland region. The impact of religion on family planning was less important. The influence of the analysed socio-economic factors on family planning was similar in rural and urban areas.

    Full Text Available The preceding review gives some insight on different methods and factors which influence the association of live weight, performance parameters with linear body measurements assessment in poultry. The relationship existing among linear body parameters provides useful information on the performance and carcass value of poultry.  Linear body measurements  variability in poultry arises due to genotypic and environmental effects, and the magnitude of variability may differs under different management practices and environmental conditions. The knowledge of the relationship existing between live weight,  carcass traits  and other performance traits in poultry is crucial because it enable us to predict the body weight and performance  from linear body parts and vice versa. This is on the background that different methods have been employed to assess the association of live weight, performance parameters with linear body measurements in poultry. It is suffice to suggest that the understating of the relationship between linear body measurements and performance traits in poultry could be useful in designing appropriate management, selection and breeding  programs for utilization of poultry genetic resources. Therefore, the conclusion that linear body measurements information for a particular poultry species or breed is important for breed or species identification and economic valuation in its utilization, might be valid.

  4. Assessment of Factors that Influence the Recruitment of Majors from Introductory Geology Classes

    2009-12-01

    In order to guide the formulation of strategies for recruiting undergraduates taking introductory geology courses into the geology program at Northern Arizona University, we surveyed 783 students in introductory geology classes and 23 geology majors in their junior and senior years. Our introductory courses (GLG100, Introduction to Geology; GLG101, Physical Geology; and GLG112, Geologic Disasters) typically enroll ~600 students each semester. The majority of students in these classes are non-majors who take them in order to satisfy a university general education requirement (called “Liberal Studies requirements” at NAU). A large proportion of these students are freshmen (51%) and sophomores (30%), and many have not yet decided on a major or are uncertain about the major they have chosen. Our analysis shows that ~7% of students in the introductory classes are possible candidates for recruitment. Although a small percentage, it represents a large number of individuals, in fact more than could be accommodated were they all to decide to major in geology. Influential factors that weigh in favor of majoring in geology include good employability, good salary potential, and opportunities for working outdoors, field work, observing nature, travel, and environmentally friendly employment. In addition, students view a career as a geologist as potentially the most fulfilling of the different science occupations (biologist, chemist, geologist, environmental scientist, physicist) and among the more environmentally friendly. However, students perceive geology to be the least difficult of the sciences, and geology occupations to be low-paying and low in prestige relative to the other sciences. These negative perceptions could be countered by providing data to introductory students showing the starting salaries of geologists in comparison to other science occupations, and by communicating the rigorous nature of the more advanced classes in the geology degree program.

  5. What factors influence mitigative capacity?

    International Nuclear Information System (INIS)

    This article builds on Yohe's seminal piece on mitigative capacity, which elaborates 'determinants' of mitigative capacity, also reflected in the IPCC's third assessment report. We propose a revised definition, where mitigative capacity is a country's ability to reduce anthropogenic greenhouse gas emissions or enhance natural sinks. By 'ability' we mean skills, competencies, fitness, and proficiencies that a country has attained which can contribute to GHG emissions mitigation. A conceptual framework is proposed, linking mitigative capacity to a country's sustainable development path, and grouping the factors influencing mitigative capacity into three main sets: economic factors, institutional ones, and technology. Both quantitative and qualitative analysis of factors is presented, showing how these factors vary across countries. We suggest that it is the interplay between the three economic factors-income, abatement cost and opportunity cost-that shape mitigative capacity. We find that income is an important economic factor influencing mitigative capacity, while abatement cost is important in turning mitigative capacity into actual mitigation. Technology is a critical mitigative capacity, including the ability to absorb existing climate-friendly technologies or to develop innovative ones. Institutional factors that promote mitigative capacity include the effectiveness of government regulation, clear market rules, a skilled work force and public awareness. We briefly investigate such as high abatement cost or lack of political willingness that prevent mitigative capacity from being translated into mitigation

    The black water and grey water source-separation sanitation system aims at efficient use of energy (biogas), water and nutrients but currently lacks evidence of economic viability to be considered a credible alternative to the conventional system. This study intends to demonstrate economic viability, identify main cost contributors and assess critical influencing factors. A technico-economic model was built based on a new neighbourhood in a Canadian context. Three implementation scales of source-separation system are defined: 500, 5,000 and 50,000 inhabitants. The results show that the source-separation system is 33% to 118% more costly than the conventional system, with the larger cost differential obtained by lower source-separation system implementation scales. A sensitivity analysis demonstrates that vacuum toilet flow reduction from 1.0 to 0.25 L/flush decreases source-separation system cost between 23 and 27%. It also shows that high resource costs can be beneficial or unfavourable to the source-separation system depending on whether the vacuum toilet flow is low or normal. Therefore, the future of this configuration of the source-separation system lies mainly in vacuum toilet flow reduction or the introduction of new efficient effluent volume reduction processes (e.g. reverse osmosis).

    2016-07-01

    Bioconcentration factors (BCFs) and bioaccumulation factors (BAFs) are widely used in scientific and regulatory programs to assess chemical hazards. There is increasing interest in also using biomagnification factors (BMFs) and trophic magnification factors (TMFs) for this purpose, especially for highly hydrophobic substances that may reach high concentrations in predatory species that occupy high trophic level positions in ecosystems. Measurements of TMFs in specific ecosystems can provide invaluable confirmation that biomagnification or biodilution has occurred across food webs, but their use in a regulatory context can be controversial because of uncertainties related to the reliability of measurements and their regulatory interpretation. The objective of this study is to explore some of the recognized uncertainties and dependencies in field BMFs and TMFs. This is accomplished by compiling a set of three simple food web models (pelagic, demersal and combined pelagic-demersal) consisting of up to seven species to simulate field BMFs and TMFs and to explore their dependences on hydrophobicity (expressed as log KOW), rates of biotransformation and growth, sediment-water fugacity ratios, and extent of food web omnivory and issues that arise when chemical concentration gradients exist in aquatic ecosystems. It is shown that empirical TMFs can be highly sensitive to these factors, thus the use of TMFs in a regulatory context must recognize these sensitivities. It is suggested that simple but realistic evaluative food web models could be used to extend BCF and BAF assessments to include BMFs and TMFs, thus providing a tool to address bioaccumulation hazard and the potential risk of exposures to elevated chemical concentrations in organisms at high trophic levels.

    2013-06-30

    Building upon advances in technology, production of natural gas from organic-rich shales is rapidly developing as a major hydrocarbon supply option in North America and around the world. The same technology advances that have facilitated this revolution - dense well spacing, horizontal drilling, and hydraulic fracturing - may help to facilitate enhanced gas recovery (EGR) and carbon dioxide (CO{sub 2}) storage in these formations. The potential storage of CO {sub 2} in shales is attracting increasing interest, especially in Appalachian Basin states that have extensive shale deposits, but limited CO{sub 2} storage capacity in conventional reservoirs. The goal of this cooperative research project was to build upon previous and on-going work to assess key factors that could influence effective EGR, CO{sub 2} storage capacity, and injectivity in selected Eastern gas shales, including the Devonian Marcellus Shale, the Devonian Ohio Shale, the Ordovician Utica and Point Pleasant shale and equivalent formations, and the late Devonian-age Antrim Shale. The project had the following objectives: (1) Analyze and synthesize geologic information and reservoir data through collaboration with selected State geological surveys, universities, and oil and gas operators; (2) improve reservoir models to perform reservoir simulations to better understand the shale characteristics that impact EGR, storage capacity and CO{sub 2} injectivity in the targeted shales; (3) Analyze results of a targeted, highly monitored, small-scale CO{sub 2} injection test and incorporate into ongoing characterization and simulation work; (4) Test and model a smart particle early warning concept that can potentially be used to inject water with uniquely labeled particles before the start of CO{sub 2} injection; (5) Identify and evaluate potential constraints to economic CO{sub 2} storage in gas shales, and propose development approaches that overcome these constraints; and (6) Complete new basin

    Full Text Available Abstract Background Under the Dutch national immunization program (NIP, childhood vaccination is not mandatory, but its recommendation by childhood vaccine providers (CVP is important for maintaining high vaccination coverage. We therefore examined factors related to providers' intentions to recommend vaccinations to parents of young children. Methods We conducted four focus group discussions with nurses and physicians who provide vaccines to children 0-4 years old in diverse regions of the Netherlands. Three groups represented CVPs at child welfare centers (CWCs serving the general population, with the fourth representing anthroposophical CWCs. Elements of the Theory of Planned Behaviour (TPB were used to design the groups; thematic analysis was used to structure and analyze the dataset. Results Four main themes emerged, including 1 perceived responsibility: to promote vaccines and discuss pros and cons with parents (although this was usually not done if parents readily accepted the vaccination; 2 attitudes toward the NIP: mainly positive, but doubts as to NIP plans to vaccinate against diseases with a low perceived burden; 3 organizational factors: limited time and information can hamper discussions with parents; 4 relationship with parents: crucial and based mainly on communication to establish trust. Compared to CVPs at standard CWCs, the anthroposophical CWCs spent more time communicating and were more willing to adapt the NIP to individual cases. Conclusions Our qualitative assessment provides an overview of beliefs associated with providers' intention to recommend vaccinations. They were motivated to support the NIP, but their intentions to recommend vaccinations were affected by the perceived relevance of the vaccines, practical issues like limited time and by certain types of resistant parents. These results will inform future studies to test the magnitude and relative impact of these factors.

  13. Selection of the important performance influencing factors for the assessment of human error under accident management situations in nuclear power plants

    International Nuclear Information System (INIS)

    This paper introduces the process and final results of selection of the important Performance Influencing Factors (PIFs) under emergency operation and accident management situations in nuclear power plants for use in the assessment of human errors. We collected two types of PIF taxonomies, one is the full set PIF list mainly developed for human error analysis, and the other is the PIFs for human reliability analysis (HRA) in probabilistic safety assessment (PSA). 5 PIF taxonomies among the full set PIF list and 10 PIF taxonomies among HRA methodologies (CREAM, SLIM, INTENT, were collected in this research. By reviewing and analyzing PIFs selected for HRA methodologies, the criterion could be established for the selection of appropriate PIFs under emergency operation and accident management situations. Based on this selection criteria, a new PIF taxonomy was proposed for the assessment of human error under emergency operation and accident management situations in nuclear power plants

    1988-01-01

    In clinical decision making, dentists routinely choose between alternative treatments such as crown vs amalgam/composite buildup, root canal vs extraction, fixed bridge vs removable partial denture, and prophylaxis vs subgingival curettage or periodontal scaling. A number of technical and patient factors can influence dentists' choice of treatment in these situations; however, little is known about their relative importance. To address this issue, a list of technical (e.g., periodontal status and caries rate) and patient (e.g., cost and patient preference) factors possibly influencing choice of treatment was developed for each pair of services. Responding to a mail questionnaire, 156 general dentists in Washington State listed the top three factors influencing their choice of service in each pair. Results revealed that dentists took different factors into account in choosing among alternative treatments. Technical factors dominated over patient concerns; only about 33 percent of the dentists considered patient factors important in choosing alternative therapies. The latter group was less preventively oriented, were solo practitioners, worked longer hours, and had lower prices. Results suggest patients may have little influence on prescriptions of therapy among experienced general dentists. PMID:3045303

    2016-09-01

    The adoption of exotic plants by indigenous herbivores in the region of introduction can be influenced by numerous factors. A botanical garden in Western Siberia was used to test various hypotheses on the adaptation of indigenous phyllophagous insects to exotic plants invasions, focusing on two feeding guilds, external leaf chewers and leaf miners. A total of 150 indigenous and exotic woody plant species were surveyed for insect damage, abundance and species richness. First, exotic woody plants were much less damaged by chewers and leaf miners than native plants, and the leaf miners' species richness was much lower on exotic than native plants. Second, exotic woody plants having a congeneric species in the region of introduction were more damaged by chewers and hosted a more abundant and species-rich community of leaf miners than plants without native congeneric species. Third, damage by chewers significantly increased with the frequency of planting of exotic host plants outside the botanical garden, and leaf miners' abundance and species richness significantly increased with residence time in the garden. Finally, no significant relationship was found between insect damage or abundance and the origin of the exotic plants. Besides the ecological implications of the results, this study also illustrates the potential of botanical gardens to test ecological hypotheses on biological invasions and insect-plant interactions on a large set of plant species.

    Chemosynthetic primary production supports hydrothermal vent ecosystems, but the extent of that productivity and its governing factors have not been well constrained. To better understand anaerobic primary production within massive vent deposits, we conducted a series of incubations at 4, 25, 50 and 90 °C using aggregates recovered from hydrothermal vent structures. We documented in situ geochemistry, measured autochthonous organic carbon stable isotope ratios and assessed microbial community composition and functional gene abundances in three hydrothermal vent chimney structures from Middle Valley on the Juan de Fuca Ridge. Carbon fixation rates were greatest at lower temperatures and were comparable among chimneys. Stable isotope ratios of autochthonous organic carbon were consistent with the Calvin-Benson-Bassham cycle being the predominant mode of carbon fixation for all three chimneys. Chimneys exhibited marked differences in vent fluid geochemistry and microbial community composition, with structures being differentially dominated by gamma (γ) or epsilon (ε) proteobacteria. Similarly, qPCR analyses of functional genes representing different carbon fixation pathways showed striking differences in gene abundance among chimney structures. Carbon fixation rates showed no obvious correlation with observed in situ vent fluid geochemistry, community composition or functional gene abundance. Together, these data reveal that (i) net anaerobic carbon fixation rates among these chimneys are elevated at lower temperatures, (ii) clear differences in community composition and gene abundance exist among chimney structures, and (iii) tremendous spatial heterogeneity within these environments likely confounds efforts to relate the observed rates to in situ microbial and geochemical factors. We also posit that microbes typically thought to be mesophiles are likely active and growing at cooler temperatures, and that their activity at these temperatures comprises the

    Full Text Available Deforestation is one of the major effects posed by the smallholder tobacco farming as the farmers heavily depend on firewood sourced from natural forest for curing tobacco. The research aims at assessing the factors that influence the harvesting of natural forest in the production of tobacco. Data is collected through the structured questionnaire from 60 randomly selected farmers. Binary logistic regression model is used to explain the significance of factors influencing natural forest harvesting. Results show that farmer experience, tobacco selling price, and agricultural training level negatively affect the harvesting of natural forests (to obtain firewood for curing tobacco significantly (p0.05 in influencing natural forest harvesting. Though farmers are exploiting the environment and at the same time increasing foreign currency earning through tobacco production, there is therefore a need to put in place policies that encourage sustainable forest product utilization such as gum plantations, subsidizing price of coal, and introducing fees, as well as penalties or taxes to the offenders.

    Optimal sperm cryopreservation is a prerequisite for the sustainable commercial application of frozen-thawed boar semen for AI. Three experiments were performed to identify factors influencing variability of postthaw sperm survival among 464 boar ejaculates. Sperm-rich ejaculate fractions were cryopre-served using a standard freezing-thawing procedure for 0.5-mL plastic straws and computer-controlled freezing equipment. Postthaw sperm motility (assessed with a computer-assisted semen analysis system) and viability (simultaneously probed by flow cytometry analysis after triple-fluorescent stain), evaluated 30 and 150 min postthaw, were used to estimate the success of cryopreservation. In the first experiment, 168 unselected ejaculates (1 ejaculate/boar), from boars of 6 breeds with a wide age range (8 to 48 mo), were cryopreserved over a 12-mo period to evaluate the predictive value of boar (breed and age), semen collection, transport variables (season of ejaculate collection, interval between collections, and ejaculate temperature exposure), initial semen traits, and sperm quality before freezing on sperm survival after freezing-thawing. In Exp. 2, 4 ejaculates from each of 29 boars, preselected according to their initial semen traits and sperm quality before freezing, were collected and frozen over a 6-mo period to evaluate the influence of interboar and intraboar ejaculate variability in the survival of sperm after cryopreservation. In Exp. 3, 12 ejaculates preselected as for Exp. 2, from each of 15 boars with known good sperm cryosurvival, were collected and frozen over a 12-mo period to estimate the sustainability of sperm cryosurvival between ejaculates over time. Boar and semen collection and transport variables were not predictive of sperm cryosurvival among ejaculates. Initial semen traits and sperm quality variables observed before freezing explained 23.2 and 10.9%, respectively, of the variation in postthaw sperm motility and viability. However, more that

    As described in this publication, since the early 1990s numerous studies based on the life cycle assessment methodology have been dedicated to assessments of different kinds of bioenergy in comparison with fossil energy resources in terms of their energy balance and environmental impact. On reviewing the results of these studies one finds a strikingly wide range of variation. One major factor of influence on the results of life cycle assessments, besides methodological factors such as the choice of allocation method, is the representativeness of the data used. Thus, widely varying results are also obtained when balance calculations and assessments are performed on energy crops with due consideration to regional and site-specific factors. To address this problem the present study endeavoured to identify region and site-specific factors and assess them in terms of their influence on the life cycle assessment of the cultivation and conversion to biogas of different kinds of energy crops. For this purpose the following questions were explored: What influence do region, site and equipment-specific factors have on the results of ecological and primary-energy-related assessments; and how large are the differences in results between region and site-specific assessments on the one hand and assessments based on general assumptions on the other? It transpires that the results of region and site-specific assessments differ from one another in terms of both the assessment of energy cropping and the assessment of the entire process chain of biogas production and conversion to electricity.

    The influences of salinity and body size on biochemical (activities of glutathione-S-transferase, lactate dehydrogenase (LDH), acetylcholinesterase and digestive enzymes amylase and CMCase), physiological (feeding and egestion rates, energy reserves) and behavioural (burrowing speed) biomarkers were examined in the infaunal polychaete Nereis diversicolor. Only a few biomarkers were affected, including increased egestion rate and activities of CMCase and LDH at higher salinity, and higher egestion rate in larger worms. These findings reinforce the status of N. diversicolor as a robust sentinel species for estuaries which are environments that are particularly productive but also particularly at risk. PMID:20642318

    In 2006, a new rotavirus vaccine (RotaTeq) was licensed in the US and recommended for routine immunization of all US infants. Because a previously licensed vaccine (Rotashield) was withdrawn from the US for safety concerns, identifying barriers to uptake of RotaTeq will help develop strategies to broaden vaccine coverage. Our qualitative assessment provides complementary data to recent quantitative surveys and suggests that physicians and parents are likely to adopt the newly licensed rotavirus vaccine. Increasing parental awareness of the rotavirus disease burden and providing physicians with timely post-marketing surveillance data will be integral to a successful vaccination program.

    Full Text Available Changes in the socio-economic environment of functioning of railroad companies and corresponding transition to market economic conditions make us deeply reconsider our relation to the human factor as the main source of increase of the level of efficiency of both individual railroad enterprises and companies in general. But, apart from exclusively humanistic (evolution relation to this process, it is necessary to find means of formalisation of professional activity of a person or certification of personnel. The article is devoted to the above stated issues. In the result of the study the article develops a model of analysis of professional activity of a person at railroad transport, which gives a possibility to numerically determine the level of intellectual, social and physical components of the human factor and also to identify directions and efficiency of investing and a model of determination of the number, which ensures optimisation of the number of personnel of enterprises and structural subdivisions. In order to identify the most significant resources that are connected with personnel, time, place, method, motivation type, obtained effect and intensity of railroad transport operation the article offers to analyse results of professional activity of personnel of each structural subdivision by the “what” is created / developed / performed (regarding professional activity, “where” (enterprise name and its subordination,“when” and “who” created (developed / performed and “how” and “why” scheme.

Because a previously licensed vaccine (Rotashield was withdrawn from the US for safety concerns, identifying barriers to uptake of RotaTeq will help develop strategies to broaden vaccine coverage. Methods We explored beliefs and attitudes of parents (n = 57 and providers (n = 10 towards rotavirus disease and vaccines through a qualitative assessment using focus groups and in-depth interviews. Results All physicians were familiar with safety concerns about rotavirus vaccines, but felt reassured by RotaTeq's safety profile. When asked about likelihood of using RotaTeq on a scale of one to seven (1 = "absolutely not;" 7 = "absolutely yes" the mean score was 5 (range = 3–6. Physicians expressed a high likelihood of adopting RotaTeq, particularly if recommended by their professional organizations and expressed specific interest in post-marketing safety data. Similarly, consumers found the RotaTeq safety profile to be favorable and would rely on their physician's recommendation for vaccination. However, when asked to rank likelihood of having their child vaccinated against rotavirus (1 = "definitely not get;" 7 = "definitely get", 29% ranked 1 or 2, 36% 3 or 4, and 35% 5 to 7. Conclusion Our qualitative assessment provides complementary data to recent quantitative surveys and suggests that physicians and parents are likely to adopt the newly licensed rotavirus vaccine.

This complex and unique sport requires athletes to appropriately distribute their speed or energy expenditure (ie, pacing within each discipline as well as over the entire event. As with most physical activity, the regulation of pacing in triathlon may be influenced by a multitude of intrinsic and extrinsic factors. The majority of current research focuses mainly on the Olympic distance, whilst much less literature is available on other triathlon distances such as the sprint, half-Ironman, and Ironman distances. Furthermore, little is understood regarding the specific physiological, environmental, and interdisciplinary effects on pacing. Therefore, this article discusses the pacing strategies observed in triathlon across different distances, and elucidates the possible factors influencing pacing within the three specific disciplines of a triathlon.

    Assessing factors that influence groundwater levels such as land use and pumping strategy, is essential to adequately manage groundwater resources. A transient numerical model for groundwater flow with infiltration was developed for the Tedori River alluvial fan (140 km2), Japan. The main water input into the groundwater body in this area is irrigation water, which is significantly influenced by land use, namely paddy and upland fields. The proposed model consists of two models, a one-dimensional (1-D) unsaturated-zone water flow model (HYDRUS-1D) for estimating groundwater recharge and a 3-D groundwater flow model (MODFLOW). Numerical simulation of groundwater flow from October 1975 to November 2009 was performed to validate the model. Simulation revealed seasonal groundwater level fluctuations, affected by paddy irrigation management. However, computational accuracy was limited by the spatiotemporal data resolution of the groundwater use. Both annual groundwater levels and recharge during the irrigation periods from 1975 to 2009 showed long-term decreasing trends. With the decline in rice-planted paddy field area, groundwater recharge cumulatively decreased to 61 % of the peak in 1977. A paddy-upland crop-rotation system could decrease groundwater recharge to 73-98 % relative to no crop rotation.

  14. Assessment of gross tumor volume motion and the influence factors during respiration for lung cancer using four-dimensional computed tomography

    International Nuclear Information System (INIS)

    Objective: This study was to assess the three-dimensional gross tumor volume(GTV) motion of lung cancer caused by respiration using four-dimensional computed tomography (4DCT), and to analyze the influence factors. Methods: Four-DCT scans of 22 lung focuses in 21 patients with lung cancer were analyzed. The gross tumor volume was contoured in all 10 respiration phases of 4DCT scans. The changes in volume of GTV, the 3D motion of the centroid,boundary of GTV and the 3D spatial motion vectors were calculated and the influence factors were analyzed. Results: The average change in volume of GTV was + 14.3%(0.2%-42.5%)/-8.4% (0.4%-38.6%), the average movement amplitude of GTV centroid and GTV boundary were (0.18±0.12)cm, (0.20±0.16)cm, (0.53±0.59)cm and (0.42±0.23)cm, (0.41±0.22)cm, (0.57±0.70)cm in medio-lateral, vertro-dorsal, cranio-caudal (CC) direction, respectively. The CC movement was larger than other directions (Z=-2.12, P=0.034; Z:-2.10, P=0.035), and no significant difference was observed in 3D motion of GTV boundary (Z=-0.81, P=0.417; Z=-0.86, 0.391). The CC motion of GTV centroid in lower lobe was larger than that in upper lobe [(0.87±0.64) and (0.35±0.49)cm, (t=-2.12, P=0.047)], and no significant difference was found in other directions [(0.23±0.10) and (0.19±0.18)cm (t=-0.49, P=0.629), (0.21±0.13) and (0.17±0.11)cm (t=0.76, P=0.460)]. There was no correlation of the 3D movement and 3D spatial motion vector of GTV to the volume of GTV (r=-0.306, -0.062, -0.279, -0.300; P=0.189, 0.796, 0.234, 0.199). Conclusions: GTV motion of patients with lung cancer is individual, the CC movement is the moat obvious, using 4DCT to assess is comparatively accurate. The motion amplitude of lower lobe focuses is larger. No significant correlation of the GTV motion to the volume was observed. Larger sample study is needed to analyze the influence of adjacency to the GTV motion. (authors)

Public dental services in New South Wales, Australia offer free clinical care and preventive advice to all adolescents under 18 years of age, particularly those from disadvantaged backgrounds. This care is provided by dental therapists and oral health therapists (therapists. It is incumbent upon clinical directors (CDs and health service managers (HSMs to ensure that the appropriate clinical preventive care is offered by clinicians to all their patients. The aims of this study were to 1 explore CDs’ and HSMs’ perceptions of the factors that could support the delivery of preventive care to adolescents, and to 2 record the strategies they have utilized to help therapists provide preventive care to adolescents. Subjects and methods: In-depth, semistructured interviews were undertaken with 19 CDs and HSMs from across NSW local health districts. A framework matrix was used to systematically code data and enable key themes to be identified for analysis. Results: The 19 CDs and HSMs reported that fiscal accountability and meeting performance targets impacted on the levels and types of preventive care provided by therapists. Participants suggested that professional clinical structures for continuous quality improvement should be implemented and monitored, and that an adequate workforce mix and more resources for preventive dental care activities would enhance therapists’ ability to provide appropriate levels of preventive care.

    Many veterinary curricula use seminars, interactive educational group formats in which some 25 students discuss questions and issues relating to course themes. To get indications on how to optimize the seminar learning process for students, we aimed to investigate relationships between factors that seem to be important for the seminar learning process, and to determine how these seminar factors account for differences in students' achievement scores. A 57-item seminar evaluation (USEME) questionnaire was administered to students right after they attended a seminar. In total, 80 seminars distributed over years 1, 2, and 3 of an undergraduate veterinary medicine curriculum were sampled and 988 questionnaires were handed in. Principal factor analysis (PFA) was conducted on 410 questionnaires to examine which items could be grouped together as indicators of the same factor, and to determine correlations between the derived factors. Multilevel regression analysis was performed to explore the effects of these seminar factors and students' prior achievement scores on students' achievement scores. Within the questionnaire, four factors were identified that influence the seminar learning process: teacher performance, seminar content, student preparation, and opportunities for interaction within seminars. Strong correlations were found between teacher performance, seminar content, and group interaction. Prior achievement scores and, to a much lesser extent, the seminar factor group interaction appeared to account for differences in students' achievement scores. The factors resulting from the present study and their relation to the method of assessment should be examined further, for example, in an experimental setup. PMID:26075625

    Full Text Available From the 90th years of the last century is the production of pigs and pork industry in the Czech Republic thanks to decreasing self-sufficiency CR in this commodity frequently discussed topic. Low and fluctuating producer ́s price, increased imports of live animals and pig meat abroad and the high costs of production are often referred as one of the critical reasons for the current situation in the livestock sector. This paper deals with the calculation of cost of production in the fattening period of pigs and assessment of the influence of selected factors on the amount of these costs. The aim of this paper is to give an overview of the production costs in the final stage of pig production and overview of the influence of selected factors (the prices per year and the size of agricultural land area of farm on the amount of costs. To meet the goal was used data of anonymous questionnaire survey of farms from the years 2006 – 2010. To quantify the cost of production was used two-stage calculation. Using analysis of variance and program STATISTICA was evaluated statistical significance of selected factors on indicators – cost items. The amount of total cost in the fattening stage of pigs increased from 2006 to 2008, in 2009 and 2010 were identified annual declines, as a result of reducing the cost of feed and labor costs. The average total cost in the fattening period of pig in the period of 2006 – 2010 amounted to 1 752.8 CZK /100 FD. Feed costs in the cost structure are the most important item in the period represented on average 65.6% of total cost in the fattening period of pigs. For farms without agricultural land, the proportion was 2.4% higher.

    According to recent findings that beside cancers traditionally considered as hormone-dependent, several other tumor types show different behavior in the two sexes, indicating the possible role of endocrine factors in the course of these diseases. The possibility that endocrine factors may influence the clinical course of human malignant melanoma is suggested by the higher survival rate in premenopausal vs. postmenopausal women or men of any ages. However, investigations on the sex hormone receptor status of human cutaneous melanomas and experiments attempting to support the epidemiological results yielded conflicting results. In our human melanoma cell lines we failed to detect steroid receptors at protein level, while quantitative PCR demonstrated that their mRNA expression level was orders of magnitude lower compared to the positive control cell lines. Sex hormones did not influence the in vitro features of the human melanoma cells considerably. On the other hand, glucocorticoid receptor was present both at mRNA and protein level, although dexamethasone was effective in vitro only at high doses. Our previous experiments showed that intrasplenic injection of human melanoma cells resulted in a significantly higher number of liver colonies in male than in female SCID mice. We now show that this difference evolves during the first day. After injection into the tail vein we did not observe gender-dependent difference in the efficiency of pulmonary colonization. Examining the pattern of metastasis formation after intracardiac injection, we have found differences between the two sexes in the incidence or number of colonies only in the case of the liver but not in other organs. We concluded that the observed phenomenon is specific to the liver; therefore we investigated the effects of 2-methoxyestradiol, an endogenous metabolite of estradiol produced mainly in the liver, with an estrogen receptor-independent antitumor activity. 2ME2 effectively inhibited melanoma cell

  2. Factors Influencing HEPA Filter Performance

    International Nuclear Information System (INIS)

    Properly functioning HEPA air filtration systems depend on a variety of factors that start with the use of fully characterized challenge conditions for system design and then process control during operation. This paper addresses factors that should be considered during the design phase as well as operating parameters that can be monitored to ensure filter function and lifetime. HEPA filters used in nuclear applications are expected to meet design, fabrication, and performance requirements set forth in the ASME AG-1 standard. The DOE publication Nuclear Air Cleaning Handbook (NACH) is an additional guidance document for design and operation HEPA filter systems in DOE facilities. These two guidelines establish basic maximum operating parameters for temperature, maximum aerosol particle size, maximum particulate matter mass concentration, acceptable differential pressure range, and filter media velocity. Each of these parameters is discussed along with data linking variability of each parameter with filter function and lifetime. Temporal uncertainty associated with gas composition, temperature, and absolute pressure of the air flow can have a direct impact on the volumetric flow rate of the system with a corresponding impact on filter media velocity. Correlations between standard units of flow rate (standard meters per minute or cubic feet per minute) versus actual units of volumetric flow rate are shown for variations in relative humidity for a 70 deg. C to 200 deg. C temperature range as an example of gas composition that, uncorrected, will influence media velocity. The AG-1 standard establishes a 2.5 cm/s (5 feet per minute) ceiling for media velocities of nuclear grade HEPA filters. Data are presented that show the impact of media velocities from 2.0 to 4.0 cm/s media velocities (4 to 8 fpm) on differential pressure, filter efficiency, and filter lifetime. Data will also be presented correlating media velocity effects with two different particle size

    Full Text Available Few studies address the ecology of herbs of Cerrado grasslands, which are ecosystems where the long dry season, high temperatures, insolation, fire and invasive grasses greatly influencing germination and the establishment of plants. We assessed germination of 13 species of Poaceae from Cerrado grasslands under nursery conditions or in germination chambers, the latter with i recently collected seeds and seeds after six months storage, ii under constant and alternating temperatures, and iii in the presence and absence of light. Germinability, mean germination time (MGT and required light were quantified to elucidate factors involved in successful germination. Germinability was low for most grasses, probably because of low seed viability. For most species, germinability and MGT were not altered by seed storage. Germination percentages were higher at alternating temperatures and in the presence of light, factors that are more similar to natural environmental situations compared with constant temperature or the absence of light. Our findings indicate that alternating temperatures and light incidence are key factors for germination of species of Poaceae. The maintenance of these environmental factors, which are crucial for the conservation of Cerrado grasslands, depends on appropriate management interventions, such as fire management and the control of biological invasion.

    The study was to generally determine the influence of a municipal landfill site and environmental factors on the distribution of keratinolytic fungi in soil. The landfill site in Sosnowiec was selected for examination. Keratinolytic fungi occurred abundantly in soils of the landfill site examined and its surrounding area. Of 495 soil samples (Petri dishes) examined, 379 (76.56%) were found to be positive for keratinolytic fungi. Altogether, 1131 strains from 26 species were isolated from the samples. Among the fungi, some species with pathogenic properties (Microsporum racemosum, M. cookei, M. gypseum, Aphanoascus fulvescens and Scopulariopsis brevicaulis) were recorded. The influence of environmental factors on the qualitative and quantitative composition of keratinolytic fungi in the soils was complex. Among these factors, exchangeable acidity (pH in 1 M KCl, in particular), faecal bacterial contamination and the level of water deficit in soil were the most important. The conclusion has been drawn that municipal landfill sites are the sources of potentially pathogenic fungi with keratinolytic properties. PMID:10959197

    Kaiser, Mary K.; Calderone, Jack B.

    1991-01-01

    Angular velocity perception is examined for rotations both in depth and in the image plane and the influence of several object properties on this motion parameter is explored. Two major object properties are considered, namely, texture density which determines the rate of edge transitions for rotations in depth, i.e., the number of texture elements that pass an object's boundary per unit of time, and object size which determines the tangential linear velocities and 2D image velocities of texture elements for a given angular velocity. Results of experiments show that edge-transition rate biased angular velocity estimates only when edges were highly salient. Element velocities had an impact on perceived angular velocity; this bias was associated with 2D image velocity rather than 3D tangential velocity. Despite these biases judgements were most strongly determined by the true angular velocity. Sensitivity to this higher order motion parameter appeared to be good for rotations both in depth (y-axis) and parallel to the line of sight (z-axis).

    Full Text Available Organic recycling of waste, taking into account sanitary safety, should be a fundamental method for recovering the nutrients present in the waste for plants and organic matter. It also refers to by-products of animal origin, which are not intended for consumption by humans. In the present research , composting of hydrated poultry slaughterhouse waste with maize straw was carried out. A combination with fodder yeast and post-cellulose lime was also introduced, which modified chemical and physico-chemical properties of the mixtures. The experiment was carried out by recording the biomass temperature for 110 days in 1.2×1.0×0.8 m reactors with perforated bottoms enabling active aeration. The following parameters were taken into consideration in the composted material: carbon, nitrogen, sulfur, respiratory activity, microorganisms, fractions of compost obtained after washing on sieves. Small amounts of fodder yeast favoured the development of microorganisms and caused a sanitary risk in the final product. At the initial stage, the temperature of raw compost in that object was several degrees lower than in the case of the composted mass without yeast addition. The addition of post-cellulose lime at ratios 6.5:1:6.5 (maize straw: poultry slaughterhouse waste: post-cellulose lime caused a change in the time of microbiological activity, and led to its inhibition in the final process. In comparison to objects with poultry waste, the highest degree of hygienization was found in the compost with post-cellulose lime (with pH close to neutral. By adjusting the ratios of substrates we can influence the microbiological activity, but the amounts of individual substrates should be determined taking into account the quality of the obtained compost.

    Stein, Tatiana

    Over the last decade, wind power has emerged as a possible source of energy and has attracted the attention of homeowners and policy makers worldwide. Many technological hurdles have been overcome in the last few years that make this technology feasible and economical. The United States has added more wind power than any other type of electric generation in 2012. Depending on the location, wind resources have shown to have the potential to offer 20% of the nation's electricity; a single, large wind turbine has the capacity to produce enough electricity to power 350 homes. Throughout the development of wind turbines, however, energy companies have seen significant public opposition towards the tall white structures. The purpose of this research was to measure peoples' perceptions on wind turbine development throughout their growth, from proposal to existing phase. Three hypotheses were developed based on the participant's political affiliation, proximity and knowledge of wind turbines. To validate these hypotheses, participants were asked an array of questions regarding their perception on economic, environmental, and social impacts of wind turbines with an online service called Amazon Mechanical Turk. The responses were from residents living in the United States and required them to provide their zip code for subsequent analysis. The analysis from the data obtained suggests that participants are favorable towards wind turbine development and would be supportive of using the technology in their community. Political affiliation and proximity to the nearest wind turbine in any phase of development (proposal, construction, existing) were also analyzed to determine if they had an effect on a person's overall perception on wind turbines and their technology. From the analysis, political affiliation was seen to be an indirect factor to understanding favorability towards wind turbines; the more liberal you are, the more supportive you will be towards renewable energy use

    Emmanuel Quansah

    Full Text Available Social factors have profound effects on health. Children are especially vulnerable to social influences, particularly in their early years. Adverse social exposures in childhood can lead to chronic disorders later in life. Here, we sought to identify and evaluate the impact of social factors on child health in Ghana. As Ghana is unlikely to achieve the Millennium Development Goals' target of reducing child mortality by two-thirds between 1990 and 2015, we deemed it necessary to identify social determinants that might have contributed to the non-realisation of this goal.ScienceDirect, PubMed, MEDLINE via EBSCO and Google Scholar were searched for published articles reporting on the influence of social factors on child health in Ghana.

    Objectives Social factors have profound effects on health. Children are especially vulnerable to social influences, particularly in their early years. Adverse social exposures in childhood can lead to chronic disorders later in life. Here, we sought to identify and evaluate the impact of social factors on child health in Ghana. As Ghana is unlikely to achieve the Millennium Development Goals’ target of reducing child mortality by two-thirds between 1990 and 2015, we deemed it necessary to identify social determinants that might have contributed to the non-realisation of this goal. Methods ScienceDirect, PubMed, MEDLINE via EBSCO and Google Scholar were searched for published articles reporting on the influence of social factors on child health in Ghana. After screening the 98 articles identified, 34 of them that met our inclusion criteria were selected for qualitative review. Results Major social factors influencing child health in the country include maternal education, rural-urban disparities (place of residence), family income (wealth/poverty) and high dependency (multiparousity). These factors are associated with child mortality, nutritional status of children, completion of immunisation programmes, health-seeking behaviour and hygiene practices. Conclusions Several social factors influence child health outcomes in Ghana. Developing more effective responses to these social determinants would require sustainable efforts from all stakeholders including the Government, healthcare providers and families. We recommend the development of interventions that would support families through direct social support initiatives aimed at alleviating poverty and inequality, and indirect approaches targeted at eliminating the dependence of poor health outcomes on social factors.

  18. Current developments in Human factor assessment

    International Nuclear Information System (INIS)

    Basic factors for a successful Human Factor-analysis are reporting systems for registration and evaluation of reportable and other events. For analysis it's crucial to find as many factors as possible which contribute to the event. Only results of a complete analysis lead to a comprehensive improvement of safety. In this context some activities of the German authorities during the last years relating to human factors will be explained. Then, the different influences to the human-machine-interface are discussed in a comprehensive model. The individual staff member and all job-based requirements are taken in consideration. Still the social aspects regarding the position within the team and technical aspects with respect to the direct human-machine-interface will be examined. Last not least organizational aspects and external factors such as laws, authorities and experts will be considered. The system 'Safety through organizational learning' is an accepted practice to improve the safety of facilities. Finally a new, very simple method to assess the safety significance of human actions in nuclear power plants will be presented and compared briefly with one well-known method. This method will be explained with the procedures during operation and inspection of nuclear power as examples, describing how human errors and their repetition can be prevented. (author)

    Full Text Available Bibliometric constructions of "knowledge maps" and "cognitive structures of science" do not differentiate between impact and influence factors. The difference can be constructedaccording to different meaning and interpretation of the terms reference and citation. Reference is "acknowledgment which one author gives to another", whereas citation is "acknowledgment which one document receives from another". Development of Information Science according to period and subject area is analyzed on the corpus of citation literature retrieved from doctoral dissertations in Information Science from 1978 to 2007 at Croatian universities. The research aim is to indicate the difference between document impact factor and author's influence factor (i.e. reference ability to produce effects on actions, behavior, and opinions of authors of doctoral theses. The influence factor serves to distinguish the key role of cited authors in time and according to the duration of the influence (the average age for cited papers of dominant authors in different periods is between eight and ten years. The difference between linear and interactive communication seems vital for the interpretation of cited half-life, i.e. the attitude of one science community towards used information resources and cognitive heritage. The analyzed corpus of 22,210 citations can be divided into three communication phases according to influence factor criteria: in the phase of dialogue and interactive communication 25% of bibliographic units are cited in the first four years; in the second phase another 25% of units are cited from the fifth to the ninth year; after ten years, in the dominant linear communication phase, approximately 30% of units are cited.

    Atria, Catherine Graczyk

    Females have been underrepresented in the study of science and science careers for decades although advancements have been made in closing this gender gap, the gap persists particularly in the physical sciences. Variables which influence a woman's desire to pursue and maintain a science course of study and career must be discovered. The United States lags behind other industrialized countries in the fields of science, math, and engineering. Females comprise an estimated half of the population; their potential contributions cannot be ignored or overlooked. This retrospective research study explores the personal experiences of ten women enrolled in science majors, with science related career plans. The goal of this study is to describe the factors that influence the participants' interest in science. The findings, the effect of science coursework, science teachers' personality and manner, other influential educational personnel, role models and mentors, external influences exclusive of school, parental influence, locus of control and positive attitudes toward science confirm what other researchers have found.

    Full Text Available Introduction It is necessary to know the factors that influence contraceptive behavior in order to overcome obstacles of contraceptive use by implementing modern family planning programs that have to be based on logistic management and directed to the client. The factor isolated till now are systematized into the two groups: the socio-demographic factors - to a greater extent associated with developing countries and the psychological factors -mainly related to developed countries. Socio-demographic f actors of the contraceptive use The most significant socio-demographic determinants of contraceptive behavior appear to be the age, women's educational level but even the educational level of the husband/partner, occupation, environment (urban/rural, some cultural factors, and high price of contraceptives. Psychological variables as a factor of contraceptive (nonuse In the group of psychological variables that influence contraceptive use it is possible to distinguish: the presence of illusion of fertility control, locus of control, level of Ego maturity, femininity and masculinity, i.e. the accepted gender roles, level of self-acceptance. The majority of the factors show that the presence of personal initiative and assertiveness are associated with higher level of contraception use.

    Multivariate statistical analysis is indispensable to assess the associations and interactions between different factors and the risk of periodontitis. Among others, regression analysis is a statistical technique widely used in healthcare to investigate and model the relationship between variables. In our work we study the impact of socio-demographic, medical and behavioral factors on periodontal health. Using regression, linear and logistic models, we can assess the relevance, as risk factors for periodontitis disease, of the following independent variables (IVs): Age, Gender, Diabetic Status, Education, Smoking status and Plaque Index. The multiple linear regression analysis model was built to evaluate the influence of IVs on mean Attachment Loss (AL). Thus, the regression coefficients along with respective p-values will be obtained as well as the respective p-values from the significance tests. The classification of a case (individual) adopted in the logistic model was the extent of the destruction of periodontal tissues defined by an Attachment Loss greater than or equal to 4 mm in 25% (AL≥4mm/≥25%) of sites surveyed. The association measures include the Odds Ratios together with the correspondent 95% confidence intervals.

    Full Text Available In this paper, we survey important factors, influencing customers to buy more from one of well known food market operating in capital city of Iran named Shahrvand. The survey studies the effects of six factors including customer's perception, persuasive factors, brand, customers' expectations, product's characteristics and special features of store on attracting more customers. We have distributed questionnaire among 196 customers who regularly visit stores and analyzed details of the data. The results indicate that customers' perception is the most important item, which includes eight components. Years of experience is the most important item in our survey followed by impact of color and working hours. Diversity of services is another factor, which plays the most important role followed by quality of services. Next, fidelity and brand are other most important factors and the name of store and risk are in lower degree of importance.

    Full Text Available Background: Intraocular pressure (IOP is the fluid pressure inside the eye and is maintained by the equilibrium between the forces determining the formation of aqueous humour and the alteration in the resistance to its outflow. IOP is important to evaluate patients who are at an increased risk of glaucoma. Clinically measurement of IOP is based on principles of indentation and applanation and such a method is called Tonometry. The tonometers used today are the Schiotz Indentataion Tonometer (ST and the Goldmann’s Applanation Tonometer (GAT. However the latter is accepted as the standard one. Aim: 1 To estimate the normal mean IOP for the population under study.2 To study the various factors- age, sex, refractive errors that influence the IOP.3 Merits and demerits of the individual tonometers. Method: A sample size of 100 cases of 200 sets of eyes was taken and divided into 2 groups, Group A with emmetropia, myopia, hypermetropia of both sexes and Group B with frank glaucomatous changes of both sexes. 3 consecutive measurements with GAT were recorded in each eye followed by ST with 5.5gm weight first followed by ST with 7.5gm weight. The whole database was recorded and statistically analysed. Results: Out of the total 200 eyes studied, Group A consisted of 168 apparently normal eyes which included emmetropes, myopes and hypermetropes and Group B comprised of 32 eyes which were frank glaucomatous cases with glaucomatous field defects. On estimating the mean IOP with the help of GAT and ST between the 2 eyes there was not a significant difference. On comparing the refractive status, myopes showed a higher IOP than hypermetropes and emmetropes. With both GAT and ST females had higher IOP than males. The mean IOP increased as age progressed. Group B studies which had frank glaucoma cases showed that the IOP measured with GAT was higher and more accurate to the actual IOP value whereas the readings with Schiotz were variable and unreliable

  18. Influence analysis for the factor analysis model with ranking data.

    Science.gov (United States)

    Xu, Liang; Poon, Wai-Yin; Lee, Sik-Yum

    2008-05-01

    Influence analysis is an important component of data analysis, and the local influence approach has been widely applied to many statistical models to identify influential observations and assess minor model perturbations since the pioneering work of Cook (1986). The approach is often adopted to develop influence analysis procedures for factor analysis models with ranking data. However, as this well-known approach is based on the observed data likelihood, which involves multidimensional integrals, directly applying it to develop influence analysis procedures for the factor analysis models with ranking data is difficult. To address this difficulty, a Monte Carlo expectation and maximization algorithm (MCEM) is used to obtain the maximum-likelihood estimate of the model parameters, and measures for influence analysis on the basis of the conditional expectation of the complete data log likelihood at the E-step of the MCEM algorithm are then obtained. Very little additional computation is needed to compute the influence measures, because it is possible to make use of the by-products of the estimation procedure. Influence measures that are based on several typical perturbation schemes are discussed in detail, and the proposed method is illustrated with two real examples and an artificial example.

    2009-07-01

    Using retrospective data from the Urban Integration Survey conducted in 2001 in Nairobi, Kenya, on a sample of 955 women and men aged 25-54, this paper compares factors influencing entry into union formation for men and women. The analysis uses event history methods, specifically Cox Proportional Hazards regression, stratified by age cohort and run separately by sex. The results indicate that delay in union formation is more pronounced for women than for men. Cohabitation without formal marriage is the prominent form of union, especially among the younger generation, and appears to have increased. For men, the timing of union is more dependent upon human capital acquisition than on cultural factors. These findings show that the marriage search model, which was first applied in Western countries, can also hold in cities of developing countries. Nonetheless, neither the search model nor the integration or the independence models apply to women's union formation, which very few exogenous factors can explain. PMID:19250585

    2016-10-01

    This manuscript overviews the pertinent research on internal color of uncured cooked meats, biochemical processes involved in meat cookery, and fundamental mechanisms governing myoglobin thermal stability. Heat-induced denaturation of myoglobin, responsible for the characteristic dull-brown color of cooked meats, is influenced by a multitude of endogenous (i.e., pH, muscle source, species, redox state) and exogenous (i.e., packaging, ingredients, storage) factors. The interactions between these factors critically influence the internal cooked color and can confuse the consumers, who often perceive cooked color to be a reliable indicator for doneness and safety. While certain phenomena in cooked meat color are cosmetic in nature, others can mislead consumers and result in foodborne illnesses. Research in meat color suggests that processing technologies and cooking practices in industry as well as households influence the internal cooked color. Additionally, the guidelines of many international public health and regulatory authorities recommend using meat thermometers to determine safe cooking endpoint temperature and to ensure product safety.

    To assess the efficacy of percutaneous transluminal angioplasty (PTA) in patients with infrapopliteal arterial disease, and to determine the influencing factor for prognosis. A total of 55 patients (60 limbs) with infrapopliteal arterial stenosis or occlusion underwent PTA. Atherosclerotic risk factors, clinical symptoms, TransAtlantic Inter-Society Consensus (TASC) classification, and vascular wall calcification were evaluated before PTA. The number of patent infrapopliteal arteries was estimated, and the outcome was evaluated by symptom relief and limb salvage. Technical success was achieved in 53/60 limbs (88.3%) and 81/93 arteries (87.1%), TASC classification (p = 0.038) and vascular calcification (p = 0.002) influenced on technical failure. During follow-up, 26 of 55 limbs (47%) achieved symptom relief and 42/55 limbs (76%) underwent limb salvage. Non-diabetic patients (9/12, 75%) were superior to diabetic patients (17/43, 40%) in terms of symptom relief (p = 0.024). TASC classification and vascular wall calcification influenced on symptom relief and limb salvage. The number of patent infrapopliteal arteries after PTA influenced symptom relief (p < 0.001) and limb amputation (p = 0.003). PTA in patients with chronic critical limb ischemia is worthwhile as a primary treatment. The influence factors should be considered before PTA, and PTA should be performed in as many involved arteries as possible.

    Most legitimate nuclear activities worldwide that are intended for peaceful purposes are currently conducted within the international nonproliferation regime, established in 1970 on the basis of the Nuclear Non-Proliferation Treaty (NPT). This regime was augmented by several consecutive treaties that arose as a result of various world events, rendering it significantly more stringent. The methodology consists of three steps: (1) structuring a criteria-tree that incorporates all the criteria and sub-criteria that influence credibility formation and demonstrates the relationships between the criteria and sub-criteria, (2) defining the weight coefficients of each criteria through pairwise comparisons of the Analytical Hierarchy Process (AHP), and (3) assigning numerical scores to a state under each criterion and combining them with weight coefficients in order to provide an overall assessment of the state. Employing the proposed methodology, the paper proceeds to assess the current level of unclear nonproliferation credibility that South Korea has reached

    Full Text Available Syneresis is the process of whey separation induced by gel contraction resulting in rearranging or restructuring of casein matrix formed during enzymatic coagulation. Numerous factors can influence the process of syneresis. The influences of pH, calcium concentration, temperature of coagulation of milk and applied heat treatment on the syneresis induced by different intensity of centrifugal force have been investigated. Coagulated samples were centrifuged at 1000, 2000 and 3000 rpm for 5 min, respectively. Reconstituted skim milk powder (control sample and reconstituted non-fat milk heat treated at 87ºC/10 min (experimental sample are coagulated at temperatures of 30ºC and 35ºC, at pH value of 5.8 and 6.2, and with the addition of 100, 200 and 400 mg/l of CaCl2, respectively. Centrifugation at 1000 rpm of both control and experimental samples didn’t recover any sera, regardless of the applied coagulation conditions. This indicates that the intensity of centrifugal force wasn’t strong enough to disrupt gel structure and cause syneresis. When the intensity of centrifugal force was increased up to 2000 rpm, the syneresis was induced, but the degree of syneresis depended on the applied factors of coagulation, primary on the applied heat treatments and temperature of coagulation. The amount of added CaCl2 didn’t have a significant influence on the induced syneresis at 2000 rpm. The induced syneresis was very significant for both control and experimental samples when the intensity of centrifugal force of 3000 rpm was applied. It was also noted that curd produced from heat treated milk in which milk protein coaggregates were formed, released less sera regardless of the applied coagulation factors.

  11. Cultural Influences on the Assessment of Children’s Pain

    2009-01-01

    Full Text Available Culture is commonly regarded as a factor in pain behaviour and experience, but the meaning of the term is often unclear. There is little evidence that pain perception is modified by cultural or ethnic factors, but pain expression by children and interpretation by caregivers may be affected by the culture of the patient or the caregiver. The present paper examines some of the research regarding cultural influences on children’s pain assessment, and addresses directions for future research. A focus on cultural influences should not distract clinicians from the need to be sensitive to individual beliefs and attitudes.

    In the previous article, we calculated dentist service rates for 200 general dentists based on a homogeneous, well-educated, upper-middle-class population of patients. Wide variations in the rates were detected. In this analysis, factors influencing variation in the rates were identified. Variation in rates for categories of dental services was explained by practice characteristics, patient exposure to fluoridated water supplies, and non-price competition in the dental market. Rates were greatest in large, busy practices in markets with high fees. Older practices consistently had lower rates across services. As a whole, these variables explained between 5 and 30 percent of the variation in the rates. PMID:2118182

    2004-01-01

    To develop a transformation protocol of Rosa hybrida 'Samantha' via Agrobacterium tumefaciens, the authors examined the effect of different factors on T-DNA transfer by measuring transient expression levels of an intron-containing β-glucuronidase gene. The results indicate that explant, light condition, salt concentration and acetosyringone (AS) concentration in co-culture medium are the most important factors, and factors like co-culture temperature, co-culture period and bacteria density have a strong effect on the growth of bacteria and then T-DNA transfer. Optimized co-cultivation was performed by inoculation of embryogenic callus with bacteria at a density of OD600= 0.5-0.8 for 20 min and co-culture in darkness under 23 °C on medium with 1/2 MS salts and 300 μmol·L-1 AS for 3 d.

  14. Organizational factors influencing improvements in safety

    International Nuclear Information System (INIS)

    Research reported here seeks to identify the key organizational factors that influence safety-related performance indicators in nuclear power plants over time. It builds upon organizational factors identified in NUREG/CR-5437, and begins to develop a theory of safety-related performance and performance improvement based on economic and behavioral theories of the firm. Central to the theory are concepts of past performance, problem recognition, resource availability, resource allocation, and business strategies that focus attention. Variables which reflect those concepts are combined in statistical models and tested for their ability to explain scrams, safety system actuations, significant events, safety system failures, radiation exposure, and critical hours. Results show the performance indicators differ with respect to the sets of variables which serve as the best predictors of future performance, and past performance is the most consistent predictor of future performance

  15. Factors influencing choice of countermeasure strategy

    International Nuclear Information System (INIS)

    There are number of countermeasures that can be used, singly and in combination, to reduce doses in the short-term following a nuclear accident. Which strategy is adopted will depend on local factors, such as the type of accident, local geography and demography, and the resources available, and on the form of national and international guidance is to facilitate a consistent level of response to accidents, wherever they occur, whilst at the same time providing for flexibility of response to suit local circumstances. This paper discusses the influence of all these factors on the choice of protective strategy. The goal of any off-site emergency response strategy should be the protection of the public, not just against radiation, but in the sense of providing overall benefit. To achieve this goal, differing local and national constraint mean that the precise strategy adopted may vary from site to site. (Authors). 22 refs., 1 fig., 2 tabs

    International Nuclear Information System (INIS)

    Following factors possibly influencing the cardiac MIBG accumulation were examined mainly in mice. 1. The specific activity of the MIBG (meta-iodo-benzyl guanidine) on the neuronal and non-neuronal fractions. 2. Motor restriction stress on MIBG accumulation and washout. 3. Loading and restriction of sodium chloride on the accumulation and effect of suppression of renin-angiotensin system. 4. Examinations in Dahl rats. 125I- or 131I-MIBG was intravenously administered to mice at 74 kBq. At 30 min or 4 hr after administration, mice were sacrificed and their left ventricles were dissected out for measurement of radioactivity in a liquid scintillation counter. Salt-sensitive and -resistant Dahl rats were given with 37 MBq of 123I-MIBG and cardiac radioactivity was measured externally for calculation of washout. Factors examined were found highly correlated with the accumulation of MIBG and measurement of its washout was considered useful for evaluating sympathetic activity. (K.H.)

    2012-01-01

    Full Text Available Background: There is a shortage of anaesthesiologists in India. The factors that prompt medical students to opt for anaesthesiology as their career are not known; neither do we have any mechanism to know a student′s stress-bearing ability before he/she opts for a stressful career like anaesthesiology. We conducted an anonymous, questionnaire-based, cross-sectional survey among 200 post-graduate anaesthesiology students to know various factors that they considered while opting for this speciality, and also evaluated their stress-bearing ability using Antonovsky′s 13-point sense of coherence scale. Methods: Two-hundred anaesthesiology students were asked to complete a questionnaire regarding the factors they considered important while opting for anaesthesiology, also enumerated in order of importance the three most important factors that led to opting this career. Students also answered the questions in Antonovsky′s sense of coherence (SOC scale. Results: Economic security was considered by maximum number of students (67.7%, while intellectual stimulation/challenge offered by anaesthesiology was rated first in order of importance. Influence of doctor−patient relationship was not considered by large number of students. The weak SOC score (55 (25 th percentile was not greatly different than the mean SOC score (60 in the survey. Conclusion: Increasing the exposure of students to anaesthesiology at undergraduate level and building public awareness about the speciality will prompt more students to opt for the speciality, while career counselling with regard to specific needs of a speciality and ability of a student will help in opting the speciality that best suits the student′s personality.

  2. Factors influencing the proliferation of nuclear weapons

    International Nuclear Information System (INIS)

    Although predicting that there will be more nuclear weapons in the future is safe enough, predicting how many more countries over what period of time, which ones under what circumstances, and how much more of what kind of nuclear-weapons capability for each is more difficult. Predicting what effect more will have is a related question that is even more difficult. This chapter identifies some of the factors that will determine the answers: including the supply policies of nuclear-exporting counties, the international nuclear-fuel cycle, superpower security policies, the health of the non-proliferation regime, cataclysmic events and international reaction, and preventive and preemptive strikes. The author concludes that more proliferation will only be better if we accept the greater probability of catastrophic wars in exchange for less frequent conventional conflicts, but he tempers this with the observation that the policies of governments can influence the course of proliferation

    Objective: To study the impact of tobacco advertisements and other social factors on the smoking habits of adolescents in Calcutta, India. Design: Cross sectional, school based survey of students in the IXth and XIth grades. The responses were analyzed by binary logistic regression. Participants: High School students in Calcutta aged 14 to 18 years. Main Outcome Measure: Smoking Status as defined by ever smokers of tobacco products. Results: 1973 students were interviewed (males-73.79% and females-26.21%). Increased tobacco use was associated with older age-groups, male gender, government-run schools, having parents or peers who were smokers, and if the respondent was also a chewer. The likelihood of a respondent being a smoker was 8.5 times greater (95% CI: 5.05-14.43) if he or she had a smoker friend, and about 4.5 times (95% CI: 2.7-7.4) if he or she had a smoker sibling. In the multivariate model, the parents' smoking status did not have a statistically significant association with respondent's smoking status. Television advertisements of tobacco products had no statistically significant association with respondents' smoking status. Conclusions: The finding of tobacco advertisements not having a significant association with smoking habits among adolescents could be due to the fact that, at the time of this survey, tobacco advertisements were not frequent in the prime channels due to Government regulations. Peer influence had the strongest association with adolescent smoking. It is therefore suggested that the peer influence factor should be considered for anti-tobacco regulatory activities that target adolescent smoking in India. PMID:12716305

    Full Text Available Abstract Background The deterioration of the health status of the Romanian population during the economic transition from a centrally planned to a free market economy has been linked to lifestyles factors (e.g. diet regarded as a main determinants of the disparity in life expectancy between Eastern and Western Europe. Reforms in the health care system in this transition economy aim to focus on preventive action. The purpose of this study was to identify the factors that impact on the individual decision to engage in Dietary Health Preventive Behaviour (DHPB and investigate their influence in the context of an adapted health cognition model. Methods A population-based study recruited 485 adult respondents using random route sampling and face-to-face administered questionnaires. Results and discussion Respondents' health motivation, beliefs that diet can prevent disease, knowledge about nutrition, level of education attainment and age have a positive influence on DHPB. Perceived barriers to healthy eating have a negative impact on alcohol moderation. The information acquisition behaviour (frequency of reading food labels is negatively predicted by age and positively predicted by health motivation, education, self-reported knowledge about nutrition and household financial status. A significant segment of respondents believe they are not susceptible to the elicited diseases. Health promotion strategies should aim to change the judgments of health risk. Conclusion The adaptation of the Health Belief Model and the Theory of Health Preventive Behaviour represents a valid framework of predicting DHPB. The negative sign of perceived threat of disease on DHPB may suggest that, under an income constraint, consumers tend to trade off long-term health benefits for short-term benefits. This cautions against the use of negative messages in public health campaigns. Raising the awareness of diet-disease relationships, knowledge about nutrition (particularly

  5. Geochemical factors influencing vault design and layout

    International Nuclear Information System (INIS)

    The design and construction of a vault for used nuclear fuel in crystalline rock may be influenced by a number of geochemical factors. During the siting stage, information is needed regarding the rock type, heterogeneities in its composition and the mineralogy of permeable zones because these will cause variations in thermal conductivity, strength and radionuclide sorptive properties of the rock. These factors may affect decisions regarding depth of vault construction, tunnel dimensions and spacing of panels and waste containers. The decision on whether groundwaters are allowed to flow freely into a planned excavation may depend on measurements of their chemical compositions, microbiological contents and presence of hazardous or corrosive constituents. During site characterization, borehole drilling from the surface and subsequent hydraulic testing will introduce both chemical and microbiological contaminants that may further influence this decision. During vault construction, the geochemistry of the rock may cause changes to the characterization, design and construction of the vault. For example, high salinity fluids in micropores in the rock could prevent the use of radar surveys to detect fractures in the surrounding rock. High rock salinity may also cause unacceptably high total dissolved solids loadings in water discharged from the facility. Again, the presence of toxic, corrosive or radioactive constituents in inflowing groundwater may require grouting or, if inflow is needed for service operations, development of treatment facilities both above and below ground. In addition, the use of explosives will cause high organic and nitrate loadings in service water as well as the possible impregnation of these chemicals in the damaged wall-rock surrounding an excavation. These chemicals may remain despite cleaning efforts and act as nutrients to promote microbial activity in the post-closure phase. In the operational phase, further design and construction, changes

    Breast milk is a noninvasive specimen to assess maternal and infant exposure to polychlorinated biphenyls (PCBs) and organochlorine pesticides (OCPs). In this study, 206 breast milk samples were collected from 87 participants during lactation, at residue levels of these contaminants measured in our study were relatively lower than those reported for European, African and Asian populations. Within a month postpartum typically after day seven the levels of ΣPCB and ΣOCP significantly increased. Some OCP compounds were correlated with maternal age, BMI, parity, and delivery mode. Certain types of dietary habits such as seafood and noodle consumption were significantly associated with ΣPCB and ΣOCP. The estimated daily intakes (EDIs) of ΣPCB and ΣOCP were 45.2-127 ng kg(-1) bw day(-1) and 625-1259 ng kg(-1) bw day(-1) during lactation, respectively, which are lower than the threshold values proposed by the US EPA and Health Canada. The exposure of Korean infants to chlordanes via breast milk had a potential health risk which deserves further investigation. PMID:24112654

    Obesity is an escalating public health challenge and contributes tremendously to the disease burden globally. New therapeutic strategies are required to alleviate the health impact of obesity-related metabolic dysfunction. Brown adipose tissue (BAT) is specialized for dissipating chemical energy for thermogenesis as a defense against cold environment. Intriguingly, the brown-fat like adipocytes that dispersed throughout white adipose tissue (WAT) in rodents and humans, called "brite" or "beige" adipocytes, share similar thermogenic characteristics to brown adipocytes. Recently, researchers have focused on cognition of these thermogenic adipose tissues. Some factors have been identified to regulate the development and function of thermogenic adipose tissues. Cold exposure, pharmacological conditions, and lifestyle can enhance non-shivering thermogenesis and metabolism via some mechanisms. However, environmental pollutants, such as ambient fine particulates and ozone, may impair the function of these thermogenic adipose tissues and thereby induce metabolic dysfunction. In this review, the origin, function and influencing factors of thermogenic adipose tissues were summarized and it will provide insights into identifying new therapeutic strategies for the treatment of obesity and obesity-related diseases.

    Background Glioblastoma multiforme (GBM) is the most malignant kind of astrocytic tumors and is associated with a poor prognosis. In this retrospective study, we assessed the clinical, radiological, genetic molecular and treatment factors that influence clinical outcomes of patients with GBM.Methods A total of 116 patients with GBM who received surgery and radiation between January 2006 and December 2007 were included in this study. Kaplan-Meier survival analysis and Cox regression analysis were used to find the factors independently influencing patients' progression free survival (PFS) time and overall survival (OS) time.Results Age, preoperative Kamofsky Performance Scale (KPS) score, KPS score change at 2 weeks after operation, neurological deficit symptoms, tumor resection extent, maximal tumor diameter, involvement of eloquent cortex or deep structure, involvement of brain lobe, Ki-67 expression level and adjuvant chemotherapy were statistically significant factors (P <0.05) for both PFS and OS in the univariate analysis. Cox proportional hazards modeling revealed that age ≤50 years, preoperative KPS score ≥80, KPS score change after operation ≥0, involvement of single frontal lobe,non-eloquent area or deep structure involvement, low Ki-67 expression and adjuvant chemotherapy were independent favorable factors (P <0.05) for patients' clinical outcomes.Conclusions Age at diagnosis, preoperative KPS score, KPS score change at 2 weeks postoperation, involvement of brain lobe, involvement of eloquent cortex or deep structure, Ki-67 expression level and adjuvant chemotherapy correlate significantly with the prognosis of patients with GBM.

    We assessed the perceived sustainability of community health programs organized by local intersectoral coalitions, as well as the factors that collaborating partners think might influence sustainability. Semi-structured interviews were conducted among 31 collaborating partners of 5 community health programs in deprived neighborhoods in the southern part of the Netherlands. The interview guide was based on a conceptual framework that includes factors related to the context, the leading organization, leadership, the coalition, collaborating partners, interventions and outcomes. Interviews were recorded, transcribed and content analyzed using NVivo 8.0. Participants in each of the programs varied in their perceptions of the sustainability of the program, but those people collaborating in pre-existing neighborhood structures expressed relatively high faith in their continuation. The participating citizens in particular believed that these structures would continue to address the health of the community in the future. We found factors from all categories of the conceptual framework that were perceived to influence sustainability. The program leaders appeared to be crucial to the programs, as they were frequently mentioned in close interaction with other factors. Program leaders should use a motivating and supportive leadership style and should act as 'program champions'. PMID:24021354

    2016-02-01

    Technical competence is an essential aspect of intraoperative performance but is in itself insufficient to ensure an optimal surgical outcome. A list of other skills complement technical ability and these relate, among others, to surgical judgment and intraoperative decision-making processes as well as the role of the operating surgeon as leader of the surgical team. This article outlines the composite set of nontechnical skills (NTS) and the factors which influence surgical performance by virtue of this skill set. A framework has been developed to allow identification, teaching, and assessment of NTS known as Nontechnical Skills for Surgeons (NOTSS), and the relevance and influence of NOTSS during the intraoperative performance of pediatric surgery is presented.

    Lavers, Jennifer L; Oppel, Steffen; Bond, Alexander L

    2016-08-01

    Marine plastic pollution is a global problem with considerable ecological and economic consequences. Quantifying the amount of plastic in the ocean has been facilitated by surveys of accumulated plastic on beaches, but existing monitoring programmes assume the proportion of plastic detected during beach surveys is constant across time and space. Here we use a multi-observer experiment to assess what proportion of small plastic fragments is missed routinely by observers, and what factors influence the detection probability of different types of plastic. Detection probability across the various types of plastic ranged from 60 to 100%, and varied considerably by observer, observer experience, and biological material present on the beach that could be confused with plastic. Blue fragments had the highest detection probability, while white fragments had the lowest. We recommend long-term monitoring programmes adopt survey designs accounting for imperfect detection or at least assess the proportion of fragments missed by observers. PMID:27363010

  4. Influence of lifestyle factors on mammographic density in postmenopausal women.

    Directory of Open Access Journals (Sweden)

    Judith S Brand

    Full Text Available BACKGROUND: Mammographic density is a strong risk factor for breast cancer. Apart from hormone replacement therapy (HRT, little is known about lifestyle factors that influence breast density. METHODS: We examined the effect of smoking, alcohol and physical activity on mammographic density in a population-based sample of postmenopausal women without breast cancer. Lifestyle factors were assessed by a questionnaire and percentage and area measures of mammographic density were measured using computer-assisted software. General linear models were used to assess the association between lifestyle factors and mammographic density and effect modification by body mass index (BMI and HRT was studied. RESULTS: Overall, alcohol intake was positively associated with percent mammographic density (P trend  = 0.07. This association was modified by HRT use (P interaction  = 0.06: increasing alcohol intake was associated with increasing percent density in current HRT users (P trend  = 0.01 but not in non-current users (P trend  = 0.82. A similar interaction between alcohol and HRT was found for the absolute dense area, with a positive association being present in current HRT users only (P interaction  = 0.04. No differences in mammographic density were observed across categories of smoking and physical activity, neither overall nor in stratified analyses by BMI and HRT use. CONCLUSIONS: Increasing alcohol intake is associated with an increase in mammography density, whereas smoking and physical activity do not seem to influence density. The observed interaction between alcohol and HRT may pose an opportunity for HRT users to lower their mammographic density and breast cancer risk.

  5. Comparative assessment of radiation versus nutritional and other factors that may influence immune status. Report of a Joint IAEA/WHO advisory group meeting, Vienna, Austria, 3-6 May 1994

    International Nuclear Information System (INIS)

    An Advisory Group Meeting was convened jointly by the International Atomic Energy Agency and the World Health Organization in May 1994 to review the role of radiation, nutrition, toxic chemicals and other factors that may influence immune status in human populations. Priorities for future research were proposed, and possibilities for using isotope in such studies were identified. The Group recommended that the IAEA should initiate a broadly based Co-ordinated Research Programme (CRP) focussed mainly on the effects of low-level radiation on immune status in human populations. The main variables of interest are (i) the level of individual radiation exposure, and (ii) the nutritional status. Possible experimental groups include persons living in areas of high radiation background (e.g. in countries where areas of high radiation background are known to occur naturally, or at high altitudes, or in areas affected by Chernobyl accident). Other possible experimental groups comprise radiation workers and uranium miners. It was also recommended that the contribution of toxic chemical exposure to immune dysfunction in these population groups should be assessed. Such research should be complemented by animal studies, and possibly also by in vitro studies with human and animal cells, by some participants in the CRP. This report has been prepared as a source of information for potential participants in the proposed CRP and for other persons associated with related programmes of the IAEA and the WHO. 15 refs, 1 fig., 7 tabs

  7. Use of Influence Diagrams and Fuzzy Theory to Develop Assessment Method of Organizational Influences on Component Maintenance

    International Nuclear Information System (INIS)

    Organization can make influences on all the systems. Especially in case of nuclear power plants in which safety is established to be one of the most important operating goals, there have been a lot of research efforts for the hardware advancement. However in recent years, it has been widely recognized that organizational factors in nuclear power plants have an important influence on the safety attitudes and the safe behavior of individuals. Until now, any means to include assessments of organizational structure in probabilistic risk assessments have not been universally accepted. The objective of this work is to develop a method to assess organizational influences on component maintenance. Influence diagrams are introduced in this method as a decision making tool and fuzzy theory is used to reflect the vagueness in considering relevance of human activities in maintenance tasks. Introducing fuzzy theory to assess the organizational factors is deemed to a somewhat new trial, which makes it possible to convert linguistic vague descriptions into mathematical ones. Fuzzy linguistic descriptions offer an alternative and often complementary language to conventional, i.e., analytic approaches to modeling systems. Among the existing methodologies to assess organizational factors, the concept of the ω-factor model is utilized and the mechanism that organizational factors have influences on component maintenance is evaluated through composing influence diagrams. These influences go to failure rates and eventually affect component unavailability. Further study will make it possible that the influences of organizational factors on human error probabilities are incorporated into human reliability analysis and furthermore probabilistic safety assessment.

    This report, Vol. 2, submitted by the General Electric Co., identifies factors that should be considered in planning interconnected systems and discusses how these factors relate to one another. The objective is to identify all the factors and classify them by their use and importance in arriving at a decision. Chapter 2 discusses the utility system and its system behavior characteristics, emphasizing behavior that affects the planning of the bulk-power generation and transmission system. Chapter 3 introduces interconnection planning by discussing the new system characteristics brought to operation and planning. Forty-two factors associated with cost, reliability, constraints, and coordination are related to each other by factor trees. Factor trees display the relationship of one factor such as reliability to more-detailed factors which in turn are further related to individual characteristics of facilities. These factor trees provide a structure to the presentation. A questionnaire including the 42 factors was completed by 52 system planners from utility companies and government authorities. The results of these questionnaires are tabulated and presented with pertinent discussion of each factor. Chapter 4 deals with generation planning, recognizing the existence of interconnections. Chapter 5 addresses transmission planning, questions related to reliability and cost measures and constraints, and factors related to both analytical techniques and planning procedures. The chapter ends with a discussion of combined generation-transmission planning. (MCW)

    2012-02-01

    INTRODUCTION: Irish general surgery faces a recruitment crisis with only 87 of 145 (60%) basic surgical training (BST) places filled in 2009. We assessed basic surgical trainees to identify objective, and potentially modifiable, factors that influence ultimate recruitment into a general surgical career. METHODS: Candidates commencing BST training during a 5-year period between 2004 and 2008 were included in a quantitative study. In addition a total of 2,536 candidates, representing all those who commenced surgical training in Ireland since 1960 were identified through the Royal College of Surgeons in Ireland (RCSI) database and invited to complete an online survey. Statistical analysis was performed using SPSS version 15, with p < 0.05 considered significant. RESULTS: During the 5-year quantitative study period there were 381 BST trainees. Gender was a significant predictor of career choice with women more likely to ultimately choose a nonsurgical career after initial surgical training (p = 0.049). Passing surgical membership examinations (MRCS) also was predictive of remaining in surgery (p = 0.005). Training region was not a significant predictor of ultimate career choice. There were 418 survey respondents. The influence of role models was most commonly cited as influencing candidates in choosing to commence surgical training. Candidates who rated "academic opportunity" (p = 0.023) and "intellectual challenge" (p = 0.047) as factors that influenced their decision to commence surgical training were more likely to ultimately continue their careers in a surgical speciality. CONCLUSIONS: This study describes the career pathway of surgical trainees and confirms the importance of academic achievement in discriminating between candidates applying for surgical training schemes.

    Mammographic density is an independent strong risk factor for breast cancer. However, the influence of factors on mammographic density in premenopausal women remains unclear. In the Southern Professional Women Breast Cancer Screening Project, we assessed the associations between mammographic density and its influential factors using multivariate logistic regression in premenopausal women adjusting for BMI, age, duration of breastfeeding, number of live births, and breast size. A total of 1699 premenopausal women aged 27 to 57 years, who had been screened by mammography, were enrolled in this cross-sectional study. Overall, 85.2% were categorized as having dense breasts (BI-RADS density 3 and 4) and 14.8% as having fatty breasts (BI-RADS density 1 and 2). In multivariate and logistic regression analysis, only BMI and age were significantly negatively correlated with mammographic density in premenopausal women (Pbreastfeeding duration, education level, family history of breast cancer, as well as breast size and sleep quality, were identified in the study. Age and BMI are negatively associated with mammographic density in premenopausal Chinese women. Information on the influential factors of mammographic density in premenopausal women might provide meaningful insights into breast cancer prevention. PMID:26075657

    Full Text Available Innovation is a broad concept and it is not in contradiction with tradition. Any entrepreneur, even when working in a traditional sector or businesses with strong traditions such as a family business can be innovative. Innovation is not only pushed by the entrepreneur but is increasingly market pulled. Through an innovation entrepreneur it is wanted to influence his market structure or to develop new markets. Radical innovations introduce new business concepts, which require an ability to organize resources and competence in novel patterns. Enterprises extend their ability to develop new business concepts, their dynamic capability, by accessing external resources. This study proposes to investigate how the use of external resources varies in the course of SMEs innovation processes, and how deployment of external resources is influenced by the nature of the innovation as well as by the context of the innovation process.

Measures of symptom and functional status, health perceptions, quality of life, oral health beliefs, and psychological (sense of coherence, self-esteem, health locus of control) and social factors (parents' income and education) were collected from 439 12- and 13-year-olds at baseline and six-month follow-up, together with a clinical examination at baseline. Structural equation modeling indicated that increased levels of caries and more symptoms predicted more functional limitations, and, cross-sectionally, greater functional impact was associated with worse health perceptions, which were linked to lower quality of life. Sense of coherence was the most important psychosocial predictor. These factors are important in understanding how oral health affects young people's daily lives. PMID:20739689

    Full Text Available The association between early life factors and body mass index (BMI in adulthood has been demonstrated in developed countries. The aim of the present study was to assess the influence of early life factors (birth weight, gestational age, maternal smoking, and social class on BMI in young adulthood with adjustment for adult socioeconomic position. A cohort study was carried out in 1978/79 with 6827 mother-child pairs from Ribeirão Preto city, located in the most developed economic area of the country. Biological, economic and social variables and newborn anthropometric measurements were obtained shortly after delivery. In 1996, 1189 males from this cohort, 34.3% of the original male population, were submitted to anthropometric measurements and were asked about their current schooling on the occasion of army recruitment. A multiple linear regression model was applied to determine variables associated with BMI. Mean BMI was 22.7 (95%CI = 22.5-23.0. After adjustment, BMI was 1.22 kg/m² higher among infants born with high birth weight (³4000 g, 1.21 kg/m² higher among individuals of low social class at birth and 0.69 kg/m² higher among individuals whose mothers smoked during pregnancy (P < 0.05. The association between social class at birth and BMI remained statistically significant (P < 0.05 even after adjustment for adult schooling. These findings suggest that early life social influences on BMI were more important and were not reversed by late socioeconomic position. Therefore, prevention of overweight and obesity should focus not only on changes in adult life styles but also on factors such as high birth weight.

    Bolt installation quality is influenced by various factors, some are well known and others are less recognised. A programme of field and laboratory studies was undertaken to examine various factors of relevance to the load transfer mechanism between the bolt, resin and rock to ensure test methods truly represent field performance. Short encapsulation tests were undertaken as part of the Australian Coal Association Research Program (ACARP) funded project (C21011) with the ultimate aim of developing standard test methods for assessing bolt encapsulation with chemical resin anchor installations. The field study consisted of a series of Short Encapsulation Pull Tests (SEPT) carried out in three mines with different geological conditions to determine the most representative and practical method of SEPT. Additional field work included installation of bolts into threaded steel tubes for subsequent removal and laboratory evaluation. A series of pull tests was carried out by installing bolts in overhead rig mounted sandstone block, cast in concrete with controlled encapsulation length. Factors of importance considered included; borehole diameter, resin annulus thickness, installation time (including bolt spin to the back and "spin at back"), the effect of gloving and hole over drill. It was found that the borehole diameter had a detrimental effect on the encapsulation bonding strength. Bolt installation time of approximately 10 s constituted an acceptable time for effective bolt installation and within the resin manufacturers recommended time of 14 s. Maintaining constant length of encapsulation was paramount for obtaining consistency and repeatability of the test results. Finally, a numerical simulation study was carried out to assess the capabilities of FLAC 2D software in simulating the pull testing of rock bolts.

  19. Intussusception: Clinical and radiographic factors influencing reducibility

    International Nuclear Information System (INIS)

    Hydrostatic reduction of intussusception by barium or air enema has been widely accepted. The five-year experience with this procedure at two children's hospitals is reviewed and the results compared to previous studies. Various clinical and radiographic factors are evaluated in relation to the reduction rate. The findings show that the more distal the intussusception is encountered, the lower the rate of reduction. However, 25% are reduced within the rectum with no evidence of increased complications. Small bowel obstruction and prolonged durations of signs and symptoms decreased the rate of reduction statistically but there is no significant increase in complication rate in those attempted, contrary to a previous report. The crescent sign (dissection sign) and age of the patient are not significant factors in reduction as reported by other studies. (orig.)

    The purpose of this study was to validate a tool that explores the factors influencing women's opinion of and attitudes towards midwifery. A descriptive, cross-sectional design was used. The sample consisted of 526 Jordanian women. Cluster sampling was used to ensure a representative sample; then, convenience sampling was performed. The instrument asked non-identifying demographic questions and covered factors reported in literature to influence women's attitudes towards and views of the profession. The resulting instrument consisted of five factors explained by 29 items. These factors were women's general view of midwives, midwife duties, professional ethics, media influence and demotivating factors associated with working as a midwife. Although the instrument is valid and reliable, it needs further testing in other studies. Taking the factors reported on by the present study into account in public policy-making could promote better understanding of midwifery and improve its status in the community. PMID:25521518

    Full Text Available The continuous supply of energy resources is essential for the development of any nation. The economic and social life of any nation depends enormously on the energy resources. Over the past few years the energy crisis is becoming a major issue in developing countries as Pakistan. Oil, Natural gas and hydro are the three major energy resources of the Pakistan. These conventional energy resources were being exploited in the past leading to an issue of energy crisis in the country. Replacing expensive imported energy resources with coal briquettes made from indigenous coal reserves can provide fuel for the local residential and commercial markets. Coal briquettes formation is a process to convert coal powder into a specific shape with the help of a binder. An external force is applied to the coal binder mixture to make a firm body of desired shape. The briquettes formed this way will not disintegrate under normal conditions of transportation and use. Coal briquettes are preferred over raw coal because they are a smokeless, strong and low emissive fuel that can be used in numerous domestic and commercial applications. The performance of coal briquettes formed is dependent largely upon its thermal properties and the mechanical strength. Nowadays an environmentally safe briquettes formation process is also included in the performance criteria of coal briquettes. The mechanical strength of coal briquettes affects its storage and transportation to the intended market. The studies on coal briquettes show that coal briquettes quality depends on many factors like the type of binder, quantity of binder, grade of coal, moisture level, coal particle size and its distribution etc. These factors along with some of the factors as time of compaction, compaction temperature, and compaction pressure and moisture level are discussed in this paper to evaluate the performance of briquetting technology in future.

  11. Factors influencing EPR dosimetry in fingernails

    International Nuclear Information System (INIS)

    The technique based on the detection of ionizing radiation induced radicals by EPR in tooth enamel is an established method for the dosimetry of exposed persons in radiological emergencies. Dosimetry based on EPR spectral analysis of fingernail clippings, currently under development, has the practical advantage of the easier sample collection. A limiting factor is that overlapping the radiation induced signal (RIS), fingernails have shown the presence of two mechanically induced signals, called MIS1 and MIS2, due to elastic and plastic deformation respectively, at the time of fingernails cutting. With a water treatment, MIS1 is eliminated while MIS2 is considerably reduced. The calibration curves needed for radiation accident dosimetry should have 'universal' characteristics, ie. Represent the variability that can be found in different individuals. Early studies were directed to the analysis of factors affecting the development of such universal calibration curves. The peak to peak amplitude of the signal before and after the water treatment as well as the effect of size and number of clippings were studied. Furthermore, the interpersonal and intrapersonal variability were analyzed. Taking into account these previous studies, the optimal conditions for measurement were determined and EPR spectra of samples irradiated at different doses were used for the developing of dose-response curves. This paper presents the analysis of the results.(authors)

    2013-03-01

    This paper investigates the factors associated with childhood immunization in Uganda. We used nationally-representative data from Uganda Demographic and Health Survey (UDHS) of 2006. Both bivariate and multivariate approaches were employed in the analysis. The bivariate approach involved generating average percentages of children who were immunized, with analysis of pertinent background characteristics. The multivariate approach involved employing maximum likelihood probit technique and generating marginal effects to ascertain the probability of being immunized, given the same background characteristics. It revealed that slightly over 50% of children in Uganda were fully immunized. Additionally, 89%, 24%, 52%, and 64% received BCG, DPT, polio and measles vaccines respectively. Factors which have a significant association with childhood immunization are: maternal education (especially at post-secondary level), exposure to media, maternal healthcare utilization, maternal age, occupation type, immunization plan, and regional and local peculiarities. Children whose mothers had post-secondary education were twice as likely to be fully immunized compared to their counterparts whose mothers had only primary education (p < 0.01). Thus, gender parity in education enhancement efforts is crucial. There is also a need to increase media penetration, maternal healthcare utilization, and to ensure parity across localities and regions. PMID:23617212

  13. Major influencing factors of indoor radon concentrations in Switzerland

    International Nuclear Information System (INIS)

    Purpose: In Switzerland, nationwide large-scale radon surveys have been conducted since the early 1980s to establish the distribution of indoor radon concentrations (IRC). The aim of this work was to study the factors influencing IRC in Switzerland using univariate analyses that take into account biases caused by spatial irregularities of sampling. Methods: About 212,000 IRC measurements carried out in more than 136,000 dwellings were available for this study. A probability map to assess risk of exceeding an IRC of 300 Bq/m3 was produced using basic geostatistical techniques. Univariate analyses of IRC for different variables, namely the type of radon detector, various building characteristics such as foundation type, year of construction and building type, as well as the altitude, the average outdoor temperature during measurement and the lithology, were performed comparing 95% confidence intervals among classes of each variable. Furthermore, a map showing the spatial aggregation of the number of measurements was generated for each class of variable in order to assess biases due to spatially irregular sampling. Results: IRC measurements carried out with electret detectors were 35% higher than measurements performed with track detectors. Regarding building characteristics, the IRC of apartments are significantly lower than individual houses. Furthermore, buildings with concrete foundations have the lowest IRC. A significant decrease in IRC was found in buildings constructed after 1900 and again after 1970. Moreover, IRC decreases at higher outdoor temperatures. There is also a tendency to have higher IRC with altitude. Regarding lithology, carbonate rock in the Jura Mountains produces significantly higher IRC, almost by a factor of 2, than carbonate rock in the Alps. Sedimentary rock and sediment produce the lowest IRC while carbonate rock from the Jura Mountains and igneous rock produce the highest IRC. Potential biases due to spatially unbalanced sampling of

    This paper assesses the factors influencing mistimed and unwanted pregnancies in Nepal separately using data from the 2011 Nepal Demographic and Health Survey. Women who had given birth within the five years before the survey were interviewed about the intendedness of their last pregnancy. The data were analysed with a chi-squared test, followed by multiple logistic regression analysis. Among the total 5391 participants, 11.29% and 13.13% reported their last pregnancy as mistimed and unwanted respectively. Logistic regression analysis showed that women from the hill region were more likely to report mistimed pregnancy, while women from the Western and Far-Western development regions were less likely to report mistimed pregnancy. Education status was positively correlated with the reporting of mistimed pregnancy. Women involved in agriculture, with full autonomy on household decision, with some exposure to mass media, belonging to higher age group and having third or higher parity were less likely to report mistimed pregnancy. Similarly, women from the Western development region had relatively higher odds of reporting unwanted pregnancy. Women with husbands involved in a paid job had lower odds of unwanted pregnancy. Women's autonomy was also positively correlated with unwanted pregnancy. Women with the intention to use contraceptive had lower odds of unwanted pregnancy. Interventions targeting the factors identified by this study could be useful in reduction of mistimed and unwanted pregnancies among Nepali women. PMID:26008148

    2015-09-01

    Poker is a social game, where success depends on both game strategic knowledge and emotion regulation abilities. Thus, poker provides a productive environment for studying the effects of emotional and social factors on micro-economic decision making. Previous research indicates that experiencing negative emotions, such as moral anger, reduces mathematical accuracy in poker decision making. Furthermore, various social aspects of the game—such as losing against "bad players" due to "bad luck"—seem to fuel these emotional states. We designed an Internet-based experiment, where participants' (N = 459) mathematical accuracy in five different poker decision making tasks were assessed. In addition, we manipulated the emotional and social conditions under which the tasks were presented, in a 2 × 2 experimental setup: (1) Anger versus neutral emotional state—participants were primed either with an anger-inducing, or emotionally neutral story, and (2) Social cue versus non-social cue—during the tasks, either an image of a pair of human eyes was "following" the mouse cursor, or an image of a black moving box was presented. The results showed that anger reduced mathematical accuracy of decision making only when participants were "being watched" by a pair of moving eyes. Experienced poker players made mathematically more accurate decisions than inexperienced ones. The results contribute to current understanding on how emotional and social factors influence decision making accuracy in economic games. PMID:24633674

    Full Text Available Background/Aim: Increased demand for colon cancer screening procedures can significantly impact on routine colonoscopy management at dedicated facilities, prompting a review of the factors that can negatively affect workflow. Although potential adverse effects and impact on costs of deep sedation have been documented elsewhere, this study focuses on variables that can influence performance of colonoscopy in deep sedation and interfere with normal procedure scheduling in settings where the presence of an anesthesiologist is mandatory. Patients and Methods: We performed a cross-sectional study of the activities of a colonoscopy screening unit, applying Bayesian Network (BN analysis, designed to assess interdependencies among variables that can affect a process in complex, multidimensional systems. The study was performed at a teaching hospital where endoscopists and anesthesiologists of varying work experience operate on a rota basis. During a six-month period, we analyzed 1485 consecutive colonoscopies performed under deep propofol sedation, administered by an anesthesiologist via hand-controlled syringe. The BN was constructed with the variables: Gender, age, ASA status, bowel preparation, baseline blood pressure, endoscopist′s experience, anesthesiologist′s experience, presence of polypectomy, and the target node, "challenging procedure." This previously undefined category refers to any events disrupting the scheduled rota. Result and Conclusion: Two distinct networks were identified. One deals mainly with relationships among the variables, patients′ demographic and clinical characteristics (procedures with polypectomy, ASA and baseline blood pressure. The other explains relationships among the variables, "challenging procedure," bowel preparation, and endoscopist′s experience. The factors associated with the anesthesiologist′s activity do not influence challenging colonoscopies.

    IT students must be trained to work efficiently as teamwork. One of the techniques that can be used to train them is through Problem-Based Learning (PBL) approach. The PBL implementation can be influenced by various factors depending on the ultimate goal of the study. This study is focusing on the IT students' perception of the PBL implementation. The student's perception is important to ensure the successfulness of the PBL implementation. Therefore, it is important to identify the factors that might influence the implementation of PBL of IT courses. This study aims to identify some catalyst factors that may influence the PBL implementation of IT courses. The study involved three (3) main phases: identifying PBL implementation factors, constructing a PBL model, and PBL model validation using statistical analysis. Four main factors are identified: PBL Characteristics, PBL Course Assessment, PBL Practices, and PBL Perception. Based on these four factors, a PBL model is constructed. Then, based on the proposed PBL model, four hypotheses are formulated and analyzed to validate the model. All hypotheses are significantly acceptable. The result shows that the PBL Characteristics and PBL Course Assessment factors are significantly influenced the PBL Practices and indirectly influenced the Students' Perception of the PBL Implementation for IT courses. This PBL model can assist decision makers in enhancing the PBL teaching and learning strategy for IT courses. It is also can be tested to other courses in the future.

    Full Text Available Fish consumption preferences are affected by individuals’ socioeconomic characteristics. The aims of the present paper were (i to obtain information on fish consumption level and frequency; (ii to investigate the associations between the socioeconomic characteristics of consumers and their preferences; and (iii to examine the influence of determinants on fish consumption. Data were gathered through a questionnaire completed by a total of 127 randomly selected individuals from different socioeconomic backgrounds from the Antakya, Turkey. The average consumption was found to be 2.98 kg/person/year for fish. Anchovies, gilt-head sea bream, and sea bass were reported as the most consumed three species, respectively. Significant differences in fish consumption were found among age groups, gender groups, and education groups, as well as between marital statuses. A majority of the consumers eat fish once a month throughout the year or only during the winter months. Fish consumption level and frequency were significantly positively correlated with education (p<0.01, income (p<0.05 and total meat consumption (p<0.01. The stepwise multiple regression model explained 41.7% (p<0.01 of the total variance for fish consumption. The amount and frequency of the consumption in the region, which is very far below the world and Turkey average especially for lower socioeconomic groups and for less-consumed fish species, can be increased by certain policies, such as training, advertising and different marketing strategies. Moreover, consumption should be distributed equally throughout the year instead of consuming only in certain seasons.

    Full Text Available This study examined correlates of degree attainment in high school dropouts. Participants were high school dropouts of Mexican American or non-Latino white descent who had no degree, a high school degree, or a GED certificate. This study was unique in that it accounted for sample bias of missing data through the use of multiple imputation, it considered students who had dropped out as early as 7th grade, and it was able to include variables found significant in previous research on returning dropouts. Logistic regression analyses identified a parsimonious set of factors which distinguished dropouts who held degrees (diploma or GED from those who did not. Similar analyses were performed to distinguish participants who had attained diplomas from those who had attained GEDs. It was estimated that 59.2% of dropouts return to obtain high school credentials. School capability, age at dropout, and socio-economic status significantly predicted degree attainment. Presence of children, higher school capability and socio-economic status were associated with GED attainment, while later grade at dropout was associated with diploma attainment. These relationships did not vary by ethnicity, although degree attainment was less likely for Mexican American dropouts. The study concludes that dropping out is not the end of a student's education, and more research should be directed toward returning dropouts. Further, the focus of such research should be expanded to include a more positive and broader range of correlates.

    Background Hysterectomy is one of the most common gynecological surgeries performed worldwide. However, women undergoing this surgery often experience negative emotional reactions. Objectives This study was done with the aim of investigating the relationship between hysterectomy and postoperative depression, three months after the procedure. Materials and Methods This longitudinal study was conducted in the province of Khorasan-Razavi in Iran, using multistage sampling. At first, three cities were selected from the province by cluster sampling; then, five hospitals were randomly selected from these cities. The participants included 53 women who were hysterectomy candidates in one of the five selected hospitals. The participants’ demographics and hysterectomy procedure information were entered into two separate questionnaires, and the Beck depression inventory (BDI) was employed to measure their severity of depression before and three months after the surgery. The statistical package for the social sciences (SPSS) version 16 was used for the statistical analysis, and a P value of < 0.05 was considered to be statistically significant. Results The means and standard deviations of the participants’ depression scores before and three months after their hysterectomies were 13.01 ± 10.1 and 11.02 ± 10.3, respectively. Although the mean score of depression decreased three months after the hysterectomy, the difference was not statistically significant. However, a significant relationship was found between the satisfaction with the outcome of the hysterectomy and the postoperative depression score (P = 0.04). Conclusions In this study, undergoing a hysterectomy did not show a relationship with postoperative depression three months after the surgery. Moreover, the only factor related to depression following a hysterectomy was satisfaction with the surgery. PMID:27066267

  4. Soil emanometry possibilities in assessment of different influences on environment

    International Nuclear Information System (INIS)

    Radioactive gas radon having origin in mineral composition of rocks is a dangerous radio-toxic element. This fact imposes a need of its detection and quantification with the aid of radon risk assessment in either geological basement or living rooms. Except for this it is possible to use the radon detection, thanks to its relatively simple measurement, for purposes of geological near-surface structure characterization because this object has also a direct influence on human environment. The goal of contribution is to present an attempt of utilization of field emanation survey (in complex with other geophysical survey methods) as means to closer and more detailed definition of that part of geological environment which is affected by both human activity of undermining and natural tectonic faults. In situ field measurements were carried out in the Homa Nitra Region whose environment is heavily burdened with such factors. (authors)

    While workers' safety risk tolerances have been regarded as a main reason for their unsafe behaviors, little is known about why different people have different risk tolerances even when confronting the same situation. The aim of this research is to identify the critical factors and paths that influence workers' safety risk tolerance and to explore how they contribute to accident causal model from a system thinking perceptive. A number of methods were carried out to analyze the data collected through interviews and questionnaire surveys. In the first and second steps of the research, factor identification, factor ranking and factor analysis were carried out, and the results show that workers' safety risk tolerance can be influenced by four groups of factors, namely: (1) personal subjective perception; (2) work knowledge and experiences; (3) work characteristics; and (4) safety management. In the third step of the research, hypothetical influencing path model was developed and tested by using structural equation modeling (SEM). It is found that the effects of external factors (safety management and work characteristics) on risk tolerance are larger than that of internal factors (personal subjective perception and work knowledge & experiences). Specifically, safety management contributes the most to workers' safety risk tolerance through its direct effect and indirect effect; while personal subjective perception comes the second and can act as an intermedia for work characteristics. This research provides an in-depth insight of workers' unsafe behaviors by depicting the contributing factors as shown in the accident causal model developed in this research. PMID:26775077

    In a stratified random sample of 41 long term care (LTC) facilities in Vancouver, 653 residents were chosen to investigate oral health needs and demands for treatment. All of the 603 dentists in the same area were questioned to assess their interest in attending the residents of the institutions. The information from each source was reviewed to identify factors influencing the oral health services to this predominantly elderly and medically compromised population. The majority (60%) of the residents were edentulous and they made infrequent demands on dentists. Two-thirds of those interviewed said that there was nothing wrong with their mouths, but most of those who were aware of a problem wanted it treated, preferably within the institution. They complained about loose or uncomfortable dentures most frequently, and many were dissatisfied with previous dental treatment. The oral mucosal lesions seen on examination were usually symptomless and associated with poor hygiene, while structurally defective dentures and deep carious lesions were not uncommon. The responding 334 dentists indicated that they enjoyed treating elderly patients, 19% had attended an LTC facility, usually to provide an emergency service, and 37% were willing to provide this service if asked. Interest, however, in the service was curtailed by pressures from private practice, concerns about inadequate training and the small demand and poor conditions in the facilities. Although the demand for treatment was not extensive from the residents, they did have problems that were not receiving care. PMID:3121247

    Full Text Available Intervention programs aimed at promoting study and work opportunities in the Information and Communications Technology (ICT field to schoolgirls have been encouraged to combat a decline in the interest among girls to study ICT at school. The goal of our study is to investigate the influence of such interventions on schoolgirls’ intentions to choose a career in the ICT field by analysing comprehensive survey data (n = 3577, collected during four interventions in Australia, using the Partial Least Squares method. Our study is also aimed at identifying other factors influencing ICT career intentions. We found that the attitude towards interventions has an indirect influence on ICT career intentions by affecting interest in ICT. Our results also challenge several existing theoretical studies by showing that factors that had previously been suggested as influencers were found to have little or no impact in this study, these being same-sex education and computer usage.

    Full Text Available The main objective of this paper is to present the factors with influence on the sustainable university management and the relationships between them. In the scientific approach we begin from a graphical model, according to which the extracurricular activities together with internal environmental factors influence students’ involvement in such activities, the university attractiveness, their academic performance and their integration into the socially-economic and natural environment (components related with sustainable development. The model emphasizes that individual performances, related to students’ participation in extracurricular activities, have a positive influence on the sustainability of university management. The results of the study have shown that the university sustainability may be influenced by a number of factors, such as students’ performance, students’ involvement in extracurricular activities or university’s attractiveness and can in turn influence implicitly also the sustainability of university management. The originality of the paper consists in the relationships study using the modeling method in general and informatics tools of modeling in particular, as well as through graphical visualization of some influences, on the sustainability university management.

  16. Population Distribution and Influencing Factors Based on ESDA

    Institute of Scientific and Technical Information of China (English)

    Lv Chen; Fan Jie; Sun Wei

    2012-01-01

    Based on the exploratory spatial data analysis (ESDA) technique and geographic information system (GIS) platform, with statistic data of counties in 2005, this paper confirms that there is a large population density gap between counties in 2005 because the Gini coefficient is 0.55. Population distribution does not change a lot during the past decades, and the southeast China is still much more densely populated than the northwest China. The global spa- tial autoeorrelation of population distribution is obvious because Moran's I scores 0.42 and local spatial autocorrelation is partly significant. Climate and elevation are still the main natural influ- encing factors. Meanwhile industrial structure and transportation significantly influence population distribution. Different combinations of natural factors have different effects on population distribution. For a long term, climate and terrain factor stability affect population distribution. But its influence will be weakened by progress of technology. Economic development is the main factor that changes population distribution for a short term.

    Full Text Available Abstract Background With increasing rates of chronic disease associated with lifestyle behavioural risk factors, there is urgent need for intervention strategies in primary health care. Currently there is a gap in the knowledge of factors that influence the delivery of preventive strategies by General Practitioners (GPs around interventions for smoking, nutrition, alcohol consumption and physical activity (SNAP. This qualitative study explores the delivery of lifestyle behavioural risk factor screening and management by GPs within a 45–49 year old health check consultation. The aims of this research are to identify the influences affecting GPs' choosing to screen and choosing to manage SNAP lifestyle risk factors, as well as identify influences on screening and management when multiple SNAP factors exist. Methods A total of 29 audio-taped interviews were conducted with 15 GPs and one practice nurse over two stages. Transcripts from the interviews were thematically analysed, and a model of influencing factors on preventive care behaviour was developed using the Theory of Planned Behaviour as a structural framework. Results GPs felt that assessing smoking status was straightforward, however some found assessing alcohol intake only possible during a formal health check. Diet and physical activity were often inferred from appearance, only being assessed if the patient was overweight. The frequency and thoroughness of assessment were influenced by the GPs' personal interests and perceived congruence with their role, the level of risk to the patient, the capacity of the practice and availability of time. All GPs considered advising and educating patients part of their professional responsibility. However their attempts to motivate patients were influenced by perceptions of their own effectiveness, with smoking causing the most frustration. Active follow-up and referral of patients appeared to depend on the GPs' orientation to preventive care, the

    Edwards, Jason R D; Davey, Jeremy; Armstrong, Kerry A

    2014-12-01

    A significant proportion of worker fatalities within Australia result from truck-related incidents. Truck drivers face a number of health and safety concerns. Safety culture, viewed here as the beliefs, attitudes and values shared by an organisation's workers, which interact with their surrounding context to influence behaviour, may provide a valuable lens for exploring safety-related behaviours in heavy vehicle operations. To date no major research has examined safety culture within heavy vehicle industries. As safety culture provides a means to interpret experiences and generate behaviour, safety culture research should be conducted with an awareness of the context surrounding safety. The current research sought to examine previous health and safety research regarding heavy vehicle operations to profile contextual factors which influence health and safety. A review of 104 peer-reviewed papers was conducted. Findings of these papers were then thematically analysed. A number of behaviours and scenarios linked with crashes and non-crash injuries were identified, along with a selection of health outcomes. Contextual factors which were found to influence these outcomes were explored. These factors were found to originate from government departments, transport organisations, customers and the road and work environment. The identified factors may provide points of interaction, whereby culture may influence health and safety outcomes. PMID:25269101

    Roch, Sylvia G; McNall, Laurel A

    2007-09-01

    The authors explored whether accountability has implications for performance ratings and investigated factors that may influence both accountability and performance ratings. Specifically, they investigated (a) whether feelings of accountability are directly related to performance ratings, (b) whether experimental manipulations that have been proposed to manipulate accountability in fact do so, and (c) the role of motivation-related constructs. They developed and tested a model of factors proposed to influence accountability and performance ratings. Results from 334 raters in an upward feedback situation in a classroom context provide empirical support that feelings of accountability influence rating level, as do perceptions of anonymity and the importance raters place on their jobs. However, neither anonymity nor importance perceptions were related to feelings of accountability. PMID:17933404

    Renewable energy is one of the key technologies through which the energy needs of the future can be met in a sustainable and carbon-neutral manner. Increasing the share of renewable energy in the total energy mix of each country is therefore a critical need. While different countries have approached this in different ways, there are some common aspects which influence the pace and effectiveness of renewable energy incorporation. This presentation looks at data and information from 34 selected countries, analyses the patterns, compares the different parameters and identifies the common factors which positively influence renewable energy incorporation. The most successful countries are analysed for their renewable energy performance against their GDP, policy/regulatory initiatives in the field of renewables, landmass, climatic conditions and population to identify the most influencing factors to bring about positive change in renewable energy share.

  2. Consumer's Online Shopping Influence Factors and Decision-Making Model

    Science.gov (United States)

    Yan, Xiangbin; Dai, Shiliang

    Previous research on online consumer behavior has mostly been confined to the perceived risk which is used to explain those barriers for purchasing online. However, perceived benefit is another important factor which influences consumers’ decision when shopping online. As a result, an integrated consumer online shopping decision-making model is developed which contains three elements—Consumer, Product, and Web Site. This model proposed relative factors which influence the consumers’ intention during the online shopping progress, and divided them into two different dimensions—mentally level and material level. We tested those factors with surveys, from both online volunteers and offline paper surveys with more than 200 samples. With the help of SEM, the experimental results show that the proposed model and method can be used to analyze consumer’s online shopping decision-making process effectively.

    This paper carries out a questionnaire survey of persons in charge of the agricultural project in the " Eleventh Five-Year National Support Program" on the level of innovation in projects and the factors influencing innovation. After the linear regression analysis of the survey data,it is found that the factors influencing the innovation in agricultural science and technology projects include the level of innovation in scientific achievements,efficiency of research methods and creation of innovation environment. Through the variance analysis of the level of innovation and its influencing factors related to different innovators,it is found that there are differences in the statistical significance of level of innovation in projects among universities,research institutes,research and extension departments directly under the government,and enterprises; there are no significant differences in the understanding of factors influencing innovation,that is,different innovators basically have the same understanding of factors influencing innovation,but the assessment on level of innovation in projects completed is different to some extent.On this basis,this paper proposes the recommendations for further strengthening the level of innovation in agricultural science and technology projects in order to provide a theoretical reference and practical basis for the project managers to effectively improve the level of agricultural science and technology project management,and enhance the level of innovation in projects.

    Nanotechnology can be described as an emerging technology and, as has been the case with other emerging technologies such as genetic modification, different socio-psychological factors will potentially influence societal responses to its development and application. These factors will play an important role in how nanotechnology is developed and commercialised. This article aims to identify expert opinion on factors influencing societal response to applications of nanotechnology. Structured interviews with experts on nanotechnology from North West Europe were conducted using repertory grid methodology in conjunction with generalized Procrustes analysis to examine the psychological constructs underlying societal uptake of 15 key applications of nanotechnology drawn from different areas (e.g. medicine, agriculture and environment, chemical, food, military, sports, and cosmetics). Based on expert judgement, the main factors influencing societal response to different applications of nanotechnology will be the extent to which applications are perceived to be beneficial, useful, and necessary, and how 'real' and physically close to the end-user these applications are perceived to be by the public.

    Full Text Available The purpose of this paper is to analyze the existing theories for the capital structure of a corporation and to determine the factors that influence the financing decisions of Romanian corporations. The gearing ratios vary a lot among Romanian corporations pointing out the fact that the internal specific factors are the ones with a greater impact upon their capital structure, and not the external factors. Our empiric research evaluates the determining factors for the debt ratio (total debt/total assets of some Romanian corporations, focusing on its explanatory variables by including them within simple and multiple econometric models. The panel data indicators computed for the companies in the Cluj area listed on the Bucharest Stock Exchange were evaluated with the OLS and FEM techniques.The results have been interpreted, pointing out that company size and asset turnover seem to have a positive influence upon the debt ratio of selected companies, while profitability and liquidity seem to influence the debt ratio of selected companies negatively.

This factor is fear.Discussion: When attending these women we may be aware of the psychological situation they are, and we should be able to identify if the woman is asking us for help when she comes to us and try to identify and treat this factor that influences the decisions the woman we attend makes.

  12. Human factors questionnaire as a tool for risk assessment

    International Nuclear Information System (INIS)

    The human factors engineering (HFE) as a discipline, and as a process, seeks to discover and to apply knowledge about human capabilities and limitations to system and equipment design, ensuring that the system design, human tasks and work environment are compatible with the sensory, perceptual, cognitive and physical attributes of the personnel who operates systems and equipment. Risk significance considers the magnitude of the consequences (loss of life, material damage, environmental degradation) and the frequency of occurrence of a particular adverse event. The questionnaire design was based on the following definitions: the score and the classification of the nuclear safety risk. The principal benefit of applying an approach based on the risk significance in the development of the questionnaire is to ensure the identification and evaluation of the features of the projects, related to human factors, which affect the nuclear safety risk, the human actions and the safety of the nuclear plant systems. The human factors questionnaire developed in this study will provide valuable support for risk assessment, making possible the identification of design problems that can influence the evaluation of the nuclear safety risk.

    Even though washing hands with soap is among the most effective measures to reduce the risk of infection, handwashing rates in infrastructure-restricted settings remain seriously low. Little is known about how context alone and in interaction with psychosocial factors influence hand hygiene behavior. The aim of this article was to explore how both contextual and psychosocial factors affect handwashing practices. A cross-sectional survey was conducted with 660 caregivers of primary school children in rural Burundi. Hierarchical regression analyses revealed that household wealth, the amount of water per person, and having a designated place for washing hands were contextual factors significantly predicting handwashing frequency, whereas the contextual factors, time spent collecting water and amount of money spent on soap, were not significant predictors. The contextual factors explained about 13% of the variance of reported handwashing frequency. The addition of the psychosocial factors to the regression model resulted in a significant 41% increase of explained variation in handwashing frequency. In this final model, the amount of water was the only contextual factor that remained a significant predictor. The most important predictors were a belief of self-efficacy, planning how, when, and where to wash hands, and always remembering to do so. The findings suggest that contextual constraints might be perceived rather than actual barriers and highlight the role of psychosocial factors in understanding hygiene behaviors. PMID:27139449

  17. Factors influencing the profitability of optimizing control systems

    International Nuclear Information System (INIS)

    Optimizing control systems supplement conventional Distributed Control Systems and Programmable Logic Controllers. They continuously implement set points, which aim at maximizing the profitability of plant operation. They are becoming an integral part of modern mineral processing plants. This trend is justified by economic considerations, optimizing control being among the most cost-effective methods of improving metallurgical plant performance. The paper successively analyzes three sets of factors, which influence the profitability of optimizing control systems, and provides guidelines for analyzing the potential value of an optimizing control system at a given operation: external factors, such as economic factors and factors related to plant feed; features of the optimizing control system; and subsequent maintenance of the optimizing control system. It is shown that pay back times for optimization control projects are typically measured in days. The OCS software used by the authors for their applications is described briefly. (author)

    1979-10-01

    Findings from a survey of 796 high school children in four districts constituting a health administrative area were examined to ascertain the factors influencing their dental disease experience, treatment received and attendance pattern. In three of the four districts, over 60% of the children were regular attenders, enjoying the benefit of less active caries than irregular attenders. However, in the remaining district, much of which consisted of depressed, inner city areas undergoing re-development, only one third were regular attenders. Several local factors, such as availability and accessibility of services, probably influenced the numbers seeking regular care, but one of the most important appeared to be the level of provision in the salaried Community Dental Service. The implications of the findings for planning improvements in local services are discussed. PMID:295706

  5. Research on Factors Influencing Individual's Behavior of Energy Management

    Science.gov (United States)

    Fan, Yanfeng

    With the rapid rise of distributed generation, Internet of Things, and mobile Internet, both U.S. and European smart home manufacturers have developed energy management solutions for individual usage. These applications help people manage their energy consumption more efficiently. Domestic manufacturers have also launched similar products. This paper focuses on the factors influencing Energy Management Behaviour (EMB) at the individual level. By reviewing academic literature, conducting surveys in Beijing, Shanghai and Guangzhou, the author builds an integrated behavioural energy management model of the Chinese energy consumers. This paper takes the vague term of EMB and redefines it as a function of two separate behavioural concepts: Energy Management Intention (EMI), and the traditional Energy Saving Intention (ESI). Secondly, the author conducts statistical analyses on these two behavioural concepts. EMI is the main driver behind an individual's EMB. EMI is affected by Behavioural Attitudes, Subjective Norms, and Perceived Behavioural Control (PBC). Among these three key factors, PBC exerts the strongest influence. This implies that the promotion of the energy management concept is mainly driven by good application user experience (UX). The traditional ESI also demonstrates positive influence on EMB, but its impact is weaker than the impacts arising under EMI's three factors. In other words, the government and manufacturers may not be able to change an individual's energy management behaviour if they rely solely on their traditional promotion strategies. In addition, the study finds that the government may achieve better promotional results by launching subsidies to the manufacturers of these kinds of applications and smart appliances.

    Factors influencing climate change perceptions have vital roles in designing strategies to enrich climate change understanding. Despite this, factors that influence smallholder farmers' climate change perceptions have not yet been adequately studied. As many of the smallholder farmers live in regions where climate change is predicted to have the most negative impact, their climate change perception is of particular interest. In this study, based on data collected from Ethiopian smallholder farmers, we assessed farmers' perceptions and anticipations of past and future climate change. Furthermore, the factors influencing farmers' climate change perceptions and the relation between farmers' perceptions and available public climate information were assessed. Our findings revealed that a majority of respondents perceive warming temperatures and decreasing rainfall trends that correspond with the local meteorological record. Farmers' perceptions about the past climate did not always reflect their anticipations about the future. A substantial number of farmers' anticipations of future climate were less consistent with climate model projections. The recursive bivariate probit models employed to explore factors affecting different categories of climate change perceptions illustrate statistical significance for explanatory variables including location, gender, age, education, soil fertility status, climate change information, and access to credit services. The findings contribute to the literature by providing evidence not just on farmers' past climate perceptions but also on future climate anticipations. The identified factors help policy makers to provide targeted extension and advisory services to enrich climate change understanding and support appropriate farm-level climate change adaptations.

  8. Factors Potentially Influencing Student Acceptance of Biological Evolution

    Science.gov (United States)

    Wiles, Jason R.

    This investigation explored scientific, religious, and otherwise nonscientific factors that may influence student acceptance of biological evolution and related concepts, how students perceived these factors to have influenced their levels of acceptance of evolution and changes therein, and what patterns arose among students' articulations of how their levels of acceptance of evolution may have changed. This exploration also measured the extent to which students' levels of acceptance changed following a treatment designed to address factors identified as potentially affecting student acceptance of evolution. Acceptance of evolution was measured using the MATE instrument (Rutledge and Warden, 1999; Rutledge and Sadler, 2007) among participants enrolled in a secondary-level academic program during the summer prior to their final year of high school and as they transitioned to the post-secondary level. Student acceptance of evolution was measured to be significantly higher than pre-treatment levels both immediately following and slightly over one year after treatment. Qualitative data from informal questionnaires, from formal course evaluations, and from semi-structured interviews of students engaged in secondary level education and former students at various stages of post-secondary education confirmed that the suspected factors were perceived by participants to have influenced their levels of acceptance of evolution. Furthermore, participant reports provided insight regarding the relative effects they perceived these factors to have had on their evolution acceptance levels. Additionally, many participants reported that their science teachers in public schools had avoided, omitted, or denigrated evolution during instruction, and several of these students expressed frustration regarding what they perceived to have been a lack of education of an important scientific principle. Finally, no students expressed feelings of being offended by having been taught about

  10. Does the influence of risk factors on accident occurrence change over time?

    Science.gov (United States)

    Elvik, Rune

    2016-06-01

    A large number of studies have been made to assess the relationship between risk factors and accident occurrence. A risk factor is any factor that makes an accident more likely to occur. Very many risk factors have been identified, for example, being under the influence of alcohol while driving, driving on slippery roads, entering complex junctions, or driving in hours of darkness. Few studies have been made to determine whether the associations between risk factors and accident occurrence remain stable over time. This paper presents examples of studies that have replicated estimates of risk. All these studies were made within a given country, using the same method, to ensure that estimates of risk are comparable. The risk factors included in the paper are: daylight, horizontal curves, junctions, road surface conditions, precipitation, drinking and driving and driver age. For all these risk factors, their association with accidents has changed over time, mostly becoming weaker. A protective factor, snow depth, is also included. Its protective effect has become smaller over time. Possible reasons for the weakening influence of risk factors are discussed. PMID:26974026

    AIM: Whether operative procedure is a risk factor influencing recurrence following resection of carcinoma in the head ofpancreas or not remains controversies. In this text we compared the recurrence rate of two operative procedure: the Whipple procedure and extended radical operation, and inquired into the factors influencing recurrence after radical resection.METHODS: From January 1995 to December 1998, 35 cases of carcinoma of pancreas underwent the Whipple operadure, 21 patients received the Extended radical operation. All patients were followed up for more than 3 years. Prognostic factors included operative procedure, size of tumor, lymph node, interstitial invasion. RESULTS: Deaths duo to recurrence within 3 years after operation were studied. The death rate was 51.4% in the Whipple procedure and 42.9% in the Extended radical operative procedure. There was a significant difference between the two groups. Recurrence occurred in 75% patients with tumor large than 4 cm, in 87.5% patients with lymph node involvement, and in 50% patients with the presence of interstitial invasion. CONCLUSION: Tumor exceeding 4 cm, lymph node involvement, and presence of interstitial invasion are high risk factors of recurrence after Whipple's procedure and extended radical operation.

    . However, to date, no information is available regarding the genetics of PGF variability. Furthermore, even though the effect of environmental factors (e.g.: cigarette smoking) on angiogenesis has been explored, no data on the influence of these factors on PGF levels have been reported so far. Here we have...... associations were strongly replicated in the Danish sample. These results, for the first time, support the hypothesis of the presence of genetic and environmental factors influencing PGF plasma variability.......Placental Growth Factor (PGF) is a key molecule in angiogenesis. Several studies have revealed an important role of PGF primarily in pathological conditions (e.g.: ischaemia, tumour formation, cardiovascular diseases and inflammatory processes) suggesting its use as a potential therapeutic agent...

    Full Text Available Stimulating innovation is one of the pressing policy challenges facing many countries in the world today. The paper analyses the external factors that Polish entrepreneurs find most detrimental to their innovative activity. A sample of 199 small and medium size enterprises (SMEs in Poland were subjected to a survey. The data collected revealed the innovation types of SMEs in Poland and external financial factors influencing innovation the most. The results show external factors such as legal regulations, access to external financing, bureaucracy of institutions, financial government support, the tax system, time necessary to comply with regulations, and crisis and instability are very important for SMEs. According to the results, process and marketing innovations are applied more frequently than product and organisational innovations. Finally, the results indicate that entrepreneurs indicate that lack of government support and weakness of tax incentives is an important barrier to the innovation process.

    Full Text Available Sustainable innovation is the inexhaustible source of development of enterprises. Within fierce market competition, only by depending on continuous innovation can an enterprise exist and develop. By conducting an exploratory factor analysis and a confirmatory factor analysis, this paper proposes a theoretical model, dividing enterprise sustainable innovation ability into three aspects: knowledge innovation capability, production innovation capability, and market innovation capability, and analyzes the influencing factors respectively. Finally, applying this theoretical model to a practical case, with system dynamics method, the simulation results show that they are consistent with real enterprise facts. Therefore, the framework of determinants of sustainable innovation built in this paper has already been verified theoretically and practically. It not only lays a theoretical foundation for further research, but also provides a clear ground for firms to improve their sustainable innovation.

    The burden of smokeless tobacco (ST) use disproportionally impacts males in rural Ohio Appalachia. The purpose of this study was to describe the cultural factors contributing to this disparity and to articulate the way in which culture, through interpersonal factors (i.e. social norms and social networks) and community factors (i.e. marketing and availability), impacts ST initiation and use of ST among boys and men in Ohio Appalachia. Fifteen focus groups and 23 individual qualitative interviews were conducted with adult (n = 63) and adolescent (n = 53) residents in Ohio Appalachian counties to ascertain factors associated with ST use and the impact of ST marketing. Transcriptions were independently coded according to questions and themes. ST use appears to be a rite of passage in the development of masculine identity in Ohio Appalachian culture. Interpersonal factors had the greatest influence on initiation and continued use of ST. Ohio Appalachian boys either emulated current ST users or were actively encouraged to use ST through male family and peer networks. Users perceived their acceptance into the male social network as predicated on ST use. Community factors, including ST advertisement and access to ST, reinforced and normalized underlying cultural values. In addition to policy aimed at reducing tobacco marketing and access, interventions designed to reduce ST use in Ohio Appalachia should incorporate efforts to (1) shift the perception of cultural norms regarding ST use and (2) address male social networks as vehicles in ST initiation.

    Urquijo, Julia; Gonzalez Tánago, Itziar; Ballesteros, Mario; De Stefano, Lucia

    2015-04-01

    Drought is considered one of the most severe and damaging natural hazards in terms of people and sectors affected and associated losses. Drought is a normal and recurrent climatic phenomenon that occurs worldwide, although its spatial and temporal characteristics vary significantly among climates. In the case of Europe, in the last thirty years, the region has suffered several drought events that have caused estimated economic damages over a €100 billion and have affected almost 20% of its territory and population. In recent years, there has been a growing awareness among experts and authorities of the need to shift from a reactive crisis approach to a drought risk management approach, as well as of the importance of designing and implementing policies, strategies and plans at country and river basin levels to deal with drought. The identification of whom and what is vulnerable to drought is a central aspect of drought risk mitigation and planning and several authors agree that societal vulnerability often determines drought risk more than the actual precipitation shortfalls. The final aim of a drought vulnerability assessment is to identify the underlying sources of drought impact, in order to develop policy options that help to enhance coping capacity and therefore to prevent drought impact. This study identifies and maps factors underlying vulnerability to drought across Europe. The identification of factors influencing vulnerability starts from the analysis of past drought impacts in four European socioeconomic sectors. This analysis, along with an extensive literature review, led to the selection of vulnerability factors that are both relevant and adequate for the European context. Adopting the IPCC model, vulnerability factors were grouped to describe exposure, sensitivity and adaptive capacity. The aggregation of these components has resulted in the mapping of vulnerability to drought across Europe at NUTS02 level. Final results have been compared with

    Lin, Tung Cheng; Lai, Ming Cheng; Yang, Shu Wen

    2016-09-01

    Web medical forums are relatively unique as knowledge-sharing platforms because physicians participate exclusively as knowledge contributors and not as knowledge recipients. Using the perspective of social exchange theory and considering both extrinsic and intrinsic motivations, this study aims to elicit the factors that significantly influence the willingness of physicians to share professional knowledge on web medical forums and develops a research model to explore the motivations that underlie physicians' knowledge-sharing attitudes. This model hypothesizes that constructs, including shared vision, reputation, altruism, and self-efficacy, positively influence these attitudes and, by extension, positively impact knowledge-sharing intention. A conventional sampling method and the direct recruitment of physicians at their outpatient clinic gathered valid data from a total of 164 physicians for analysis in the model. The empirical results support the validity of the proposed model and identified shared vision as the most significant factor of influence on knowledge-sharing attitudes, followed in descending order by knowledge-sharing self-efficacy, reputation, and altruism.

  14. Radium concentration factors and their use in health and environmental risk assessment

    International Nuclear Information System (INIS)

    Radium is known to be taken up by aquatic animals, and tends to accumulate in bone, shell and exoskeleton. The most common approach to estimating the uptake of a radionuclide by aquatic animals for use in health and environmental risk assessments is the concentration factor method. The concentration factor method relates the concentration of a contaminant in an organism to the concentration in the surrounding water. Site specific data are not usually available, and generic, default values are often used in risk assessment studies. This paper describes the concentration factor method, summarizes some of the variables which may influence the concentration factor for radium, reviews reported concentration factors measured in marine environments and presents concentration factors derived from data collected in a study in coastal Louisiana. The use of generic default values for the concentration factor is also discussed

    Donahue, Elizabeth

    What factors influence ninth grade students' expectations for success in science? Using social cognitive theory and bioecological systems theory as theoretical frameworks, this dissertation employs data from the High School Longitudinal Study of 2009 (HSLS:09) to examine the relative impact of teacher practices and their perceived attitudes on students' science self-efficacy. Further, as they relate to this broader issue, the relative impact of student subjective task value and teacher characteristics is also investigated. It has been well documented that U.S. students are not achieving at satisfactory levels in science. Education policy has focused on improving science teacher quality as one way to address this problem. Teacher effectiveness has been primarily measured by student achievement on standardized tests. However, not enough attention has been given to the social cognitive factors that can lead to increased achievement and persistence in science as well as how teachers may influence these factors. This study interrogates the relationship between student and teacher variables and the social cognitive construct of self-efficacy, which has proven to have a significant impact on student achievement and persistence in science. Findings add to the current literature surrounding ways that educators may increase student performance in science by employing policies and practices that benefit the development of student science self-efficacy.

    The goal of this study was to identify the factors and program characteristics that influenced the program ranking decisions of applicants to pediatric dentistry residency programs. A questionnaire was sent to the first-year resident class in 2005 with a response rate of 69.2 percent (n=260). Approximately 55 percent were female (104/180) and 61 percent were non-His-panic white (110/180). The respondents reported that they applied to an average of nine programs, of which five were ranked. Most applicants were interested in a program that had a hospital component with a duration of two years. A program's ability to prepare the resident for an academic career was a minimal influence for 48.6 percent (87/179), and 57.5 percent (103/179) were not interested in a master's or Ph.D. degree. Factors associated with program ranking included modern clinical facilities, high ratio of dental assistants and faculty to residents, availability of assistants for sedation and general anesthesia cases, availability of a salary or stipend, and amount of clinical experience. Important non-clinical factors included hospitality during the interview, geographic location, and perceived reputation of the program. Opportunity to speak with the current residents in private, observing the interaction between residents and faculty, and touring the facilities were also highly considered. These findings may help program directors tailor their interviews and programs to suit the needs of applicants. PMID:17761626

    Background Deciding how to manage an unruptured intracranial aneurysm can be difficult for patients and physicians due to controversies about management. The decision as to when and how to intervene may be variable depending on physicians’ interpretation of available data regarding natural history and morbidity and mortality of interventions. Another significant factor in the decision process is the patients’ conception of the risks of rupture and interventions and the psychological burden of harboring an unruptured intracranial aneurysm. Objective  To describe which factors are being considered when patients and their physicians decide how to manage unruptured intracranial aneurysms.  Materials & methods  In a retrospective chart review study, we identified patients seen for evaluation of an unruptured intracranial aneurysm. Data was collected regarding patient and aneurysm characteristics. The physician note pertaining to the management decision was reviewed for documented reasons for intervention. Results  Of 88 patients included, 36 (41%) decided to undergo open or endovascular surgery for at least one unruptured intracranial aneurysm. Multiple aneurysms were present in 14 (16%) patients. Younger patients and current smokers were more likely to undergo surgery, but gender and race did not affect management. Aneurysm size and location strongly influenced management. The most common documented reasons underlying the decision of whether to intervene were the risk of rupture, aneurysm size, and risks of the procedure. For 23 aneurysms (21%), there were no factors documented for the management decision.  Conclusion  The risk of rupture of unruptured intracranial aneurysms may be underestimated by currently available natural history data. Major factors weighed by physicians in management decisions include aneurysm size and location, the patient's age, and medical comorbidities along with the risk of procedural complications.

  2. Critical factors in environmental impact assessment

    International Nuclear Information System (INIS)

    Environmental impact assessment (EIA) has shown that it is of proven benefit to the overall planning and environmental management of resource development projects, but certain elements within the application and practice of EIA remain problematic for proponents and regulatory decision makers alike. The use of the word 'critical' in the title of this paper suggests that if the components identified are not considered or implemented properly through the process of EIA, the product will be of less value to both the proponent and decision maker. In the context of EIA, the regulatory, financial, legal and social benefits that accrue make the need for good EIA practice even more imperative. A discussion is included that highlights a number of issues that need to be addressed to improve the effectiveness of EIA, a tool necessary to attaining provincial and federal regulatory approvals. To a large extent, the discussion reflects items of contemporary public concern, and those emerging issues of the scientific and regulatory community. At the same time, it needs to be realized that not all the identified items are necessarily new to the practice of impact assessment, but are nonetheless important to professional environmental impact assessment and decision making. Insight is also provided into the direction of decision making of the Energy and Utilities Board as it will affect the regulatory review and administration of resource development projects in the province of Alberta. 16 refs

    2016-01-01

    A continued increase in the proportion of adolescents who never smoke, as well as an understanding of factors that influence reductions in smoking among this susceptible population, is crucial. The World Health Organization Framework Convention on Tobacco Control provides an appropriate structure to briefly examine Australian and New South Wales policies and programs that are influencing reductions in smoking among adolescents in Australia. This paper provides an overview of price and recent tax measures to reduce the demand for tobacco, the evolution of smoke-free environment policies, changes to tobacco labelling and packaging, public education campaigns, and restrictions to curb tobacco advertising. It also discusses supplyreduction measures that limit adolescents' access to tobacco products. Consideration is given to emerging priorities to achieve continued declines in smoking by Australian adolescents. PMID:26863168

    Service rate variations have focused attention on treatment decisions. The aims of this study were to examine factors considered in choosing treatments, to classify dentists in terms of clinical decision making, and to investigate the association of decision making with services provided. From a random sample of dentists (response rate 60.3%) treatment constraints (15.0%), periodontal status (12.1%), tooth status (11.3%), mouth status (10.1%), and patient factors (9.8%) were considered important factors across six alternative treatment pair choice scenarios. Cluster analysis of the treatment choice scenarios produced one cluster that reflected patient preferences, another that reflected treatment constraints such as cost, and a third that reflected oral health factors. Compared with the oral health cluster, dentists in the constraints cluster had higher rates (p services (RR = 1.78) such as oral hygiene instruction. Although a range of factors influenced treatment choice, a limited set accounted for the majority of responses, with cost a major determinant, ahead of oral health status and patient preference. Decision-making style was associated with service provision. PMID:12174535

  9. Influence of expertise on rockfall hazard assessment using empirical methods

    Science.gov (United States)

    Delonca, Adeline; Verdel, Thierry; Gunzburger, Yann

    2016-07-01

    To date, many rockfall hazard assessment methods still consider qualitative observations within their analysis. Based on this statement, knowledge and expertise are supposed to be major parameters of rockfall assessment. To test this hypothesis, an experiment was carried out in order to evaluate the influence of knowledge and expertise on rockfall hazard assessment. Three populations were selected, having different levels of expertise: (1) students in geosciences, (2) researchers in geosciences and (3) confirmed experts. These three populations evaluated the rockfall hazard level on the same site, considering two different methods: the Laboratoire des Ponts et Chaussées (LPC) method and a method partly based on the "slope mass rating" (SMR) method. To complement the analysis, the completion of an "a priori" assessment of the rockfall hazard was requested of each population, without using any method. The LPC method is the most widely used method in France for official hazard mapping. It combines two main indicators: the predisposition to instability and the expected magnitude. Reversely, the SMR method was used as an ad hoc quantitative method to investigate the effect of quantification within a method. These procedures were applied on a test site divided into three different sectors. A statistical treatment of the results (descriptive statistical analysis, chi-square independent test and ANOVA) shows that there is a significant influence of the method used on the rockfall hazard assessment, whatever the sector. However, there is a non-significant influence of the level of expertise of the population the sectors 2 and 3. On sector 1, there is a significant influence of the level of expertise, explained by the importance of the temporal probability assessment in the rockfall hazard assessment process. The SMR-based method seems highly sensitive to the "site activity" indicator and exhibits an important dispersion in its results. However, the results are more similar

    Factors influencing clinical treatment of partially dentate patients are varied, and there is a need to identify factors influencing success in the provision of removable partial dentures. The aim of this study was to assess the attitudes of general dental practitioners (GDPs) in Ireland towards tooth replacement and use of RPDs, in partially dentate older adults. The sample frame was the Register of Dentists in Ireland; data were also collected from a sample of dentists practising under NHS regulations in Northern Ireland. Validated questionnaires were sent to all dentists on the Register of Dentists in the Republic of Ireland, and dentists working under NHS regulations registered with the Central Services Agency in Northern Ireland. Content of the questionnaire included details of the dentist themselves, their dental practice and the profile of partial denture provision. They were also asked to give their views on factors influencing the success or failure of an RPD, the process of providing RPDs and their attitudes to RPD provision. A total of 1,143 responses were received, a response rate of 45%. A mean number of 61 RPDs per annum were provided, with 75% of dentures provided being acrylic based. Respondents indicate their belief that cobalt-chromium based dentures had a longer prognosis than acrylic dentures, but less than half (46%) claim to design the frameworks themselves. Patients' attitudes are considered influential in the success of RPD provision, and their influence on appearance is considered the most important factor influencing success. The most important factors influencing failure are: the patient not requesting a denture; an RPD restoring unbounded saddles; and, lower RPDs. Although considered important, approximately 60% of the sample do not routinely organise follow-up appointments for patients provided with RPDs. The fee structures in the DTSS and DTBS are considered a barrier to quality in the provision of partial dentures. PMID:21192619

    Full Text Available Purpose – The purpose of this paper is to look at the factors driving online shopping and to develop an understanding of the factors influencing the online shopping by the consumers. This is done by exploring the factors that encourage consumers to shop online through analysis of such advantages as security, fast delivery, comparable price, convenience, cheaper prices and a wider choice. At the same time, the research project reveals the factors that are discouraging for consumers and the benefits received by buyers making purchases online. Specifically, the research explores how online shopping can be affected by such factors as age, gender or occupation. Design/methodology/approach – The factors that affect the consumer online shopping have been disclosed through quantitative research by analysing data collected via a web‐based questionnaire survey. The sample consisted of 183 Lithuanian consumers who were purchasing online. Findings –The empirical findings of this study indicate that the main factors influencing consumers to shop online are convenience, simplicity and better price. Analysis of socio-demographical characteristics such as gender has shown that men shop more often online because of the lower price. Respondents of the 25–35 year age group more often choose shopping online for such reasons as lack of time and a wide range of products. The most beneficial factor of shopping online was identified as a possibility to compare prices and buy at a lower price. Research limitations/implications – This study was done regarding only general conditions and the findings may not necessarily be applicable to a particular e-business. Therefore, in the future it would be highly encouraged to examine consumers’ attitudes towards specialized online shopping websites to look for differences by kind of products or services.Practical implications – Attributes identified by this study could help e-business developers to forme their

  15. The performance shaping factors influence analysis on the human reliability for NPP operation

    International Nuclear Information System (INIS)

    The Human Reliability Analysis (HRA) is an important step in Probabilistic Safety Assessment (PSA) studies and offers an advisability for concrete improvement of the man - machine - organization interfaces, reliability and safety. The goals of this analysis are to obtain sufficient details in order to understand and document all-important factors that affect human performance. The purpose of this paper is to estimate the human errors probabilities in view of the negative or positive effect of the human performance shaping factors (PSFs) for the mitigation of the initiating events which could occur in Nuclear Power Plant (NPP). Using THERP and SPAR-H methods, an analysis model of PSFs influence on the human reliability is performed. This model is applied to more important activities, that are necessary to mitigate 'one steam generator tube failure' event at Cernavoda NPP. The results are joint human error probabilities (JHEP) values estimated for the following situations: without regarding to PSFs influence; with PSFs in specific conditions; with PSFs which could have only positive influence and with PSFs which could have only negative influence. In addition, PSFs with negative influence were identified and using the DOE method, the necessary activities for changing negative influence were assigned. (authors)

    To assess the relationship of cognitive factors to a pregnant woman's decision to seek prenatal care, a semi-structured interview instrument was administered to 30 women soon after they were seen for care. A content analysis of interview transcripts was performed to identify variables affecting the decision to seek care. Variables were coded numerically, and those correlated with number of weeks gestation at first visit for pregnancy care were entered into a stepwise linear multiple regression model. Three variables accounted for 74% of the variance in the week of gestation at which pregnancy care began. Women who desired the pregnancy, wished confirmation of the pregnancy, and experienced pregnancy-related symptoms tended to seek care earlier. Results were discussed in terms of the usefulness of this integration of quantitative and qualitative methods for the study of factors related to seeking pregnancy care and the need to consider cognitive factors when designing programs to improve the delivery of prenatal care.

    Full Text Available The needs to develop improved varieties of maize have been in the heart of various researchers and institutions in Nigeria because of its strategic role in tackling food insecurity and poverty. Despite substantial efforts to improve maize varieties, the level of adoption of improved maize varieties (IMV in Nigeria in still very low. Although previous adoption studies have indicated a number of socioeconomic and institutional/organizational variables as important factors influencing adoption of improved maize (crop varieties in the country, whether these factors are the main issues of concern, and whether the inclusion of regional/agro-ecological variables in adoption model are also important in explaining what could drive farmers’ adoption behaviour requires investigation. This study therefore examined factors influencing adoption of IMV among farmers in Nigeria using a selected portion of the Nigeria Living Standard Measurement Survey data collected by the National Bureau of Statistics and the World Bank for 2010/2011 cropping season with descriptive statistics and probit model as tools for data analysis. The results suggest, in line with some previous studies, that farm size, education level of farmers and access to extension services would significantly influence adoption of IMV. The results also indicate that farmers across the entire agro-ecological regions of country share some negative sentiments regarding adoption of IMV. Renewed emphasis on interventions that would enable farmers gain more access to farmland, and promote formal education and extension service are advocated. An attempt to incorporate variables that capture farmers’ perception/experience on agroclimatic/ ecologically related concerns in adoption study could aid better understand of what drives farmers’ adoption decisions across the country especially in the light of the emerging climate change issues and its implication on food production.

    Dengue fever is a debilitating and infectious disease that could be life-threatening. It is caused by the dengue virus which affects millions of people in the tropical area. Currently, there is no cure for the disease as there is no vaccine available. Thus, prevention of the vector population using conventional methods is by far the main strategy but has been found ineffective. A genetically modified (GM) mosquito is among the favoured alternatives to curb dengue fever in Malaysia. Past studies have shown that development and diffusion of gene technology products depends heavily upon public acceptance. The purpose of this study is to identify the relevant factors influencing stakeholders' attitudes toward the GM Aedes mosquito and to analyse the relationships between all the factors using the structural equation model. A survey was carried out on 509 respondents from various stakeholder groups in the Klang Valley region of Malaysia. Results of the survey have confirmed that public perception towards complex issues such as gene technology should be seen as a multi-faceted process. The perceived benefit-perceived risk balance is very important in determining the most predominant predictor of attitudes toward a GM mosquito. In this study the stakeholders perceived the benefit of the GM mosquito as outweighing its risk, translating perceived benefit as the most important direct predictor of attitudes toward the GM mosquito. Trust in key players has a direct influence on attitudes toward the GM mosquito while moral concern exhibited an indirect influence through perceived benefits. Other factors such as attitudes toward technology and nature were also indirect predictors of attitudes toward the GM mosquito while religiosity and engagement did not exhibited any significant roles. The research findings serve as a useful database to understand public acceptance and the social construct of public attitudes towards the GM mosquito to combat dengue. PMID:24906652

    A review was made on the research progress of wear behavior of PM steels in recentyears. Wear is not an intrinsic property of PM steels, which is strongly influencedby the wear test conditions. However, many other factors that determine the me-chanical properties of PM steels also affect the wear behavior. Porosity has differenteffects on the wear of PM steels depending on the application conditions. Under drysliding condition, higher porosity results in lower wear resistance. The influence ofmicrostructures on wear resistance was in the order: carbide, martensite, bainite andlamellar pearlite. The wear resistance increases with hardness, but this relationshipchanges with the porosity and microstructures of PM steels.``

    Objective Given the public health importance of improving dietary behavior in chronic disease prevention in low- and middle-income countries it is crucial to understand the factors influencing dietary behavior in these settings. This study tested the validity of a conceptual framework linking individual and environmental factors to dietary behavior among Ecuadorian adolescents aged 10–16 years. Methods A cross-sectional survey was conducted in 784 school-going Ecuadorian adolescents in urban and rural Southern Ecuador. Participants provided data on socio-economic status, anthropometry, dietary behavior and its determining factors. The relationships between individual (perceived benefits and barriers, self-efficacy, habit strength, and a better understanding of healthy food) and environmental factors (physical environment: accessibility to healthy food; social environment: parental permissiveness and school support), and their association with key components of dietary behavior (fruit and vegetables, sugary drinks, breakfast, and unhealthy snack intake) were assessed using structural equation modeling. Results The conceptual model performed well for each component of eating behavior, indicating acceptable goodness-of-fit for both the measurement and structural models. Models for vegetable intake and unhealthy snacking showed significant and direct effects of individual factors (perceived benefits). For breakfast and sugary drink consumption, there was a direct and positive association with socio-environmental factors (school support and parental permissiveness). Access to healthy food was associated indirectly with all eating behaviors (except for sugary drink intake) and this effect operated through socio-environmental (parental permissiveness and school support) and individual factors (perceived benefits). Conclusion Our study demonstrated that key components of adolescents’ dietary behaviors are influenced by a complex interplay of individual and

  1. Studies on influence of biological factors on concentration of radionuclides

    International Nuclear Information System (INIS)

    Biological factors influencing the concentration of radionuclides were studied from the points of uptake through digestive tract, food as pathways, and metabolic activities. The uptake of radionuclides by marine fishes through digestive tract was determined by whole body counter. 137Cs, 65Zn, 131I, 54Mn, 60Co, 85Sr, and 144Ce were used as tracers and was given with solid feed. The feed given was excreated 24 to 48 hours later in small of middle sized fishes, and 20 to 48 hours later in large sized fishes. The uptake rate of 137Cs and 65Zn was high absorption of 20 to 80 per cent, that of 131I, 60Co and 54Mn was not remarkable, and that of 85Sr and 144Ce was low absorption. The biological concentration of 137Cs through pathways of food. In fishes taking up radionuclides through contaminated food, concentration factor increased in accordance with contamination level. In addition, radionuclides with small uptake but delayed excretion and those with high concentration rate could be the factors to decide the concentration factors of marine organisms. In order to study the relationship between metabolic activities and concentration, the uptake of one-year old fishes and adult fishes, and fishes fed and those non-fed were compared. One-year fishes took up large amount of 85Sr during short period, however, concentration by metabolism in adult fishes was slow. Comparing feeding group and non-feeding group, the former showed 85Sr concentration factor of 1.5 to 2 times that of the later, and the later showed 137Cs concentration factor of 2 to 4 times that of the former. However, both uptake and excretion were rapid suggesting that taking food activated the metabolism of substances. (Kanao, N.)

  2. Particulate pollution in ventilated space: Analysis of influencing factors

    International Nuclear Information System (INIS)

    Particle pollution has been identified to be a major indoor air pollution problem as many epidemiologic evidences have indicated that the particle exposure affects the occupant health. In common practice, mechanical ventilation is introduced to maintain a satisfactory indoor air quality for the occupant, which includes the area of particle control within the space. In order to have an effective control to the indoor particle pollution, it is important to understand the major factors influencing the indoor particle concentration in the breathing zone. This study employs a previously proposed approach to study the particle pollution in a typical ventilation system. The model simultaneously takes into account the interactions between particle transport in ventilation ducts and rooms and particle spatial distribution. It has been proven that an entire ventilation system, including filters, ducts and rooms, can be regarded as a serial of filters in steady-state cases, hence the name 'particle filter group model'. The particle concentration in the breathing zone is calculated under different conditions, and the result is then validated by experimental data. Based on the results, four main factors that affect the particle concentration in the breathing zone are identified, they are fresh air rate, particle filter efficiency, the type of the ventilation duct (roughness) and ventilation modes. Their degrees of influence are analyzed and then the possible measures to improve/control the indoor particle pollution are suggested

    Gene variants encoding several of the alcohol-metabolizing enzymes, alcohol dehydrogenase (ADH) and aldehyde dehydrogenase (ALDH), are among the largest genetic associations with risk for alcohol dependence. Certain genetic variants (i.e., alleles)--particularly the ADH1B*2, ADH1B*3, ADH1C*1, and ALDH2*2 alleles--have been associated with lower rates of alcohol dependence. These alleles may lead to an accumulation of acetaldehyde during alcohol metabolism, which can result in heightened subjective and objective effects. The prevalence of these alleles differs among ethnic groups; ADH1B*2 is found frequently in northeast Asians and occasionally Caucasians, ADH1B*3 is found predominantly in people of African ancestry, ADH1C*1 varies substantially across populations, and ALDH2*2 is found almost exclusively in northeast Asians. Differences in the prevalence of these alleles may account at least in part for ethnic differences in alcohol consumption and alcohol use disorder (AUD). However, these alleles do not act in isolation to influence the risk of AUD. For example, the gene effects of ALDH2*2 and ADH1B*2 seem to interact. Moreover, other factors have been found to influence the extent to which these alleles affect a person's alcohol involvement, including developmental stage, individual characteristics (e.g., ethnicity, antisocial behavior, and behavioral undercontrol), and environmental factors (e.g., culture, religion, family environment, and childhood adversity).

    Full Text Available The present study was undertaken to identify factors that influences biosecurity adoption on laying hen farmers in Sidrap district, South Sulawesi. This district was choosen because beside it was famous as the center of laying hen farms, it was also as one of districts in South Sulawesi which suffered from Avian influenza outbreak. Total samples were 60 respondents. The samples were choosen through stratified random sampling from two subdistricts which had the most populous of layer smallholders, namely Baranti and Maritengngae. Data were obtained through observations and interviews using a questionnaire. Data were analyzed using a score based on biosecurity status. Biosecurity status was obtained based on the adoption of biosecurity measures which consisted of 9 stages: farm inputs, traffic onto farms, distance from sources of pathogens to shed, exposure of farm, biosecurity at farm boundary, biosecurity between farm boundary and shed, biosecurity at the shed door, traffic into the shed and susceptibility of the flock. Multiple regression model was employed to analyze the data. The study revealed that the adoption biosecurity were associated with gender, age, education, farming experience, farm-income, family size and social capital. These variables contributed 20% variation in biosecurity adoption of laying hen farms. However, only farm income, family size and social capital were the major factors influencing to the adoption of biosecurity (P<0.05.

    Full Text Available Reformation in Indonesian government offices leads to many substantial changes, and demands improved job performances while arguably loading employees with more work. This research aims to understand factors that potentially influence job performance in Indonesian government of- fices that carries on such reformation. Using adapted scales from previous studies, this research investigates the role of workload, responsibility for others (level of responsibility to care for other people and need for achievement on employee’s performance. A survey to all full-time workers in an Indonesian government office is conducted. Contrary to expectation, workload does not influ- ence employee’s performance. Instead, regression analysis demonstrates that, employee’s need for achievement and responsibility for others are significant factors affecting individual performance. These results are important because they highlight the significance of need for achievement for the success of reformation in this office, and by extension for reformation in Indonesia. The results are also interesting because this is the first study that points out to the role of responsibility for others in influencing individual performance in Indonesia which is characterized by collectivistic culture. This paper discusses the contributions of these results for theory and practice.

  6. Influencing factors of embryo rescue in seedless grape

    International Nuclear Information System (INIS)

    In this study, we investigated the impact of inoculating stage, medium type and concentration of plant growth regulators on embryo rescue effectiveness by L25(5)6 orthogonal design using selfed ovules of Venus Seedless as the testing material. The main results were as follows. The most important factor influencing ovule germination was inoculating stage. Ovule germinating rate gradually increased as inoculating being postponed. The highest germinating rate appeared when inoculation was done 55d after flowering. Other influencing factors were IBA concentration, exogenous amino acid, 6-BA concentration, GA3 concentration and medium type in descending order. The best embryo rescue result was based on Nitsch medium including 1.0 mg/L IBA, 0.1 mg/L GA3, 0.7 mg /L 6-BA and 2.0 mmol/L glutamine using ovules inoculated 55d after flowering. The highest germinating rate reached 41.25%, and a batch of seedlings was also obtained. (author)

    Groundwater drought is a specific type of drought that concerns groundwater bodies. It may have a significant adverse effect on the socio-economic, agricultural, and environmental conditions. Investigating the effect of response different climatic and manmade factors on groundwater drought provides essential information for sustainable planning and management of water resources. The aim of this study is to identify the influencing factors on groundwater drought in a drought prone region in Bangladesh to understand the forcing mechanisms. The Standardised Precipitation Index (SPI) and Reconnaissance Drought Index (RDI) have been used to quantify the aggregated deficit between precipitation and the evaporative demand of the atmosphere. The influence of land use patterns on the groundwater drought has been identified by calculating spatially distributed groundwater recharge as a function of land use. The result shows that drought intensity is more severe during the dry season (November to April) compared to the rainy season (May to October). The evapotranspiration and rainfall deficit has a significant effect on meteorological drought which has a direct relation with groundwater drought. Urbanization results in a decrease of groundwater recharge which increases groundwater drought severity. Overexploitation of groundwater for irrigation and recurrent meteorological droughts are the main causes of groundwater drought in the study area. Efficient irrigation management is essential to reduce the growing pressure on groundwater resources and ensure sustainable water management. More detailed studies on climate change and land use change effects on groundwater drought are recommended.

    Full Text Available The paper presents the results of experiments to determine the influence of selected physico-chemical factors - oxygen, visible light and temperature - on the decomposition of (1 chlorophylls a, b and c, chlorophyll a derivatives and beta-carotene in acetone solution, and (2 chlorophyll a and beta-carotene in axenic cultures of the blue-green algae Anabaena variabilis. The results indicate that both in acetone extracts and in blue-green algae cultures these pigments were most sensitive to light and oxygen; temperatures of up to 25oC had no marked influence on these compounds. Under anoxia in acetone solution, the stability towards light decreased in the order chlorophyll a, chlorophyll b, chlorophylls c. Chlorophyll a, moreover, was less stable than its derivatives - phaeophorbides, phaeophytins, pyrophaeophytins and steryl chlorins - but more stable than beta-carotene, in the last case also in the blue-green algae cultures. Decomposition of all the pigments proceeded mainly via the breakdown of the porphyrin macrocycle, since the decomposition products were not detected in the VIS range. On the basis of these experiments one can state that while light and oxygen may have a decisive direct influence on the distribution of chlorophylls and beta-carotene in sediments, in the natural environment, temperatures of up to 25oC may have very little immediate effect.

    Reactive halogen radicals (e.g. Br, Cl atoms and their oxides, BrO, ClO) are important oxidizers in the troposphere that decrease atmospheric pollutants and deplete tropospheric ozone, affecting the abundance of other oxidizers such as the hydroxyl radical. During Arctic springtime, the heterogeneous chemical cycles (often called the "bromine explosion") produce high levels of bromine monoxide (BrO), through reactions on saline snow, ice, and/or aerosol surfaces. Multi-AXis Differential Optical Absorption Spectroscopy (MAX-DOAS) measured BrO at Barrow, AK, from 2008-2009 and 2012-2015, as well at various locations above the frozen Arctic Ocean with O-Buoys in 2008 and 2011-2015. Observed BrO levels drop suddenly during late spring (May-June) and generally do not recover, which indicates the bromine explosion cycle can no longer produce significant amounts of BrO. We have established, through an objective algorithm, the local day of year of this drop in BrO as the "seasonal end." Additionally, in about half of the years, "recurrence" events were observed where BrO levels recover for at least a day. This study investigates the environmental factors influencing seasonal end and recurrence events including: temperature, relative humidity, precipitation and snowmelt. Analysis of BrO and air temperature revealed the temperature reaches 0°C within five days of the seasonal end event; however, temperatures drop below freezing during a recurrence event. In addition, there are periods where the temperature remains below freezing, but no recurrence event is observed. This BrO and temperature analysis indicates above-freezing air temperature prevents reactive bromine release; however, it is not the only environmental factor influencing this heterogeneous recycling. Further analysis of additional environmental influences on the bromine explosion cycle could help to better understand and model bromine chemistry in the Arctic.

    Full Text Available Context: The total time spent in nursing care depends on the type of patient and the patient′s condition. We analysed factors that influenced the time spent in nursing a patient. Aims : To analyse the factors in a patient′s condition that influenced time spent in nursing a patient. Materials and Methods: This study was performed in the Surgical Intensive Care Unit of a tertiary referral centre, over a period of one month. The total time spent on a patient in nursing care for the first 24 hours of admission, was recorded. This time was divided into time for routine nursing care, time for interventions, time for monitoring and time for administering medications. Statistical analysis used: A backward stepwise linear regression analysis using the age, sex, diagnosis, type of admission and ventilatory status as variables, was done. Results: Patients admitted after elective surgery required less time (852.4 ± 234.1 minutes, than those admitted after either emergency surgery (1069.5 ± 187.3 minutes, or directly from the ward or the emergency room (1253.7 ± 42.1 minutes. Patients who were ventilated required more time (1111.5 ± 132.5 minutes, than those brought on a T-piece (732.2 ± 134.8 minutes or extubated (639.5 ± 155.6 minutes. The regression analysis showed that only the type of admission and the ventilatory status significantly affected the time. Conclusions : This study showed that the type of admission and ventilatory status significantly influenced the time spent in nursing care. This will help optimal utilization of nursing resources.

  12. Factors influencing the production of nitrous-oxide during denitrification

    International Nuclear Information System (INIS)

    In the last five years there has been a renewed interest in soil denitrification; this interest has been stimulated by the suggestion that soil evolved nitrous oxide (N2O) contributes to the depletion of the Earth's ozone layer. Although it has generally been found that dinitrogen (N2) is the major product of denitrification in soils, under some conditions large quantities of N2O are also produced. The microbiological factors which promote the production of N2O rather than N2 are not well understood. The environmental parameters controlling N2O evolution can operate at the biological level by influencing the production of N2O versus N2 or at a soil structural level by controlling the diffusion of N2O through the soil matrix. The factors which influence the biological production of N2O were investigated using 13N labeled NO3- and NO2- generated by proton bombardment of water using the 16O(p,α)13N reaction. Use of the radioactive isotope allowed very sensitive direct quantitation of N2, N2O and NO and permitted experimentation with extremely small additions of electron acceptor (about 68 fg NO3--N). 13NO3- was added to two soils and three denitrifying bacterial cultures so that N2O from denitrification was 13N-labeled. In bacterial cultures and in the heterogeneous bacterial flora of soils, the [13N]-N2O intermediate exchanged readily and quantitatively with an added pool of nonlabeled N2O. This indicates that N2O is obligatory intermediate of denitrification, and exists as a free intermediate capable of diffusion away from the sites of active reduction. This provides some understanding of why environmental factors can influence N2O production relative to N2 since any factor which produces a change in the relative rate of N2O reduction compared to the rate of N2O production can result in N2O free to diffuse away from the active site

    Full Text Available In the current situation many experts and ordinary people are asking themselves: Where is the economy heading? How can we counteract the disruptive factors? Which strategies must be employed? How should the risks be properly assessed in order to diminish them to the lowest level? What measures should be taken to improve the situation? This requires a necessary economic and financial analysis, based on the data from the financial statements, the discovery and application of risk assessment methods and the detection of procedures to mitigate this risk. It is also necessary to draw a comparison between the expected results of a rational and scientific research, and those obtained through empirical processes by means of marketing.

    Full Text Available The authors present results of researches whose aim was to determine the factors that may substantially influence population reproduction in the Republic of Serbia, taking into consideration all specific factors, like cultural background, economic situation, health education, health service organization, religious and historical factors, etc. The research was based on the population census from 1981. Seventeen regions of the inner part of the Republic of Serbia, Vojvodina and Kosovo were included in this research. Stratification was made according to the place of living (village, town age, occupation (farmer, housewife, non and half-qualified, qualified and highly qualified workers and education (without education, with unfinished or finished primary school, with secondary school, with college or university degree. In this way 2,141 women were questioned with 101 questions by the method of interview. Interviews were conducted exclusively by doctors - gynaecologists. We determined the frequency of the use of contraceptives, intentional abortions, spontaneous abortions, pre-term deliveries, marriage infertility and term deliveries. Thus, 57.4% of women had basic knowledge of contraception, but only 15.9% of them used it; 58.9% of women had intentional abortions; 16.2% of women had spontaneous abortions, 5.1% of them had pre-term deliveries, and 67% of women had term deliveries. Marriage infertility was found in 8.6% of women. When evaluating population health and behavior, we obtained some information and data concerning addicted diseases (alcohol, smoking, drugs, tranquilizers homosexuality and ways of sexual intercourse. It was concluded that enormous differences existed among certain regions in the Republic of Serbia, which were conditioned by the diversity of the above mentioned influences. Proposals for the measures to be undertaken in the Republic of Serbia in order to regulate population policy, are given.

    2008-06-01

    Full Text Available Juvenile ungulates are generally more vulnerable to predation than are adult ungulates other than senescent individuals, not only because of their relative youth, fragility, and inexperience, but also because of congenital factors. Linnell et al.’s (Wildl. Biol. 1: 209-223 extensive review of predation on juvenile ungulates concluded that research was needed to determine the predisposition of these juveniles to predation. Since then, various characteristics that potentially predispose juvenile ungulates have emerged including blood characteristics, morphometric and other condition factors, and other factors such as birth period, the mother’s experience, and spatial and habitat aspects. To the extent that any of the physical or behavioral traits possessed by juvenile ungulates have a genetic or heritable and partly independent epigenetic component that predisposes them to predation, predators may play an important role in their natural selection. We review the possible influence of these characteristics on predisposing juvenile ungulates to predation and discuss natural selection implications and potential selection mechanisms. Although juvenile ungulates as a class are likely more vulnerable to predation than all but senescent adults, our review presents studies indicating that juveniles with certain tendencies or traits are killed more often than others. This finding suggests that successful predation on juveniles is more selective than is often assumed. Because we are unable to control for (or in some cases even measure the myriad of other possible vulnerabilities such as differences in sensory abilities, intelligence, hiding abilities, tendency to travel, etc., finding selective predation based on the relatively few differences we can measure is noteworthy and points to the significant role that predation on juveniles has in the natural selection of ungulates. Future research should compare characteristics, especially those known to

    Studies of medical student performance have focused on various factors, including premedical academics, maturity, familial background and support, and personal experiences with illness. Most studies have been conducted in countries with highly developed educational systems and similar cultural and social systems. It is not clear that these findings can be applied to developing countries, where the educational and cultural experiences may be very different, and where medical instruction is carried out in a non-native language. Information was obtained from a survey of 153 fifth- and sixth-year medical students at King Abdulaziz University in Saudi Arabia. The survey measured premedical educational, social and cultural experiences that might affect medical school performance. Men performed as well as women in the medical school despite heavy familial and social commitments. Women's performance seems to be more influenced by changes in living environment. Achievement in premedical years was correlated positively with grade performance in medical school. Competence in the high-school English courses was related to medical school performance. Interest in the study of medicine prior to medical school was not related to performance. Other motivations, such as social gains, financial benefits or family wish, were related to lower performance. Current interest in clinical medicine correlated negatively with performance. Students motivated by the presence of chronic ill health in their families performed significantly lower. Factors influencing medical school performance in developed countries had similar impact on medical students in a developing country. Social factors, unique to the country, also play a role in medical student performance. PMID:2355866

    Clarification of influencing factors is of great importance in suspected occupational liver diseases. Hints are given on the basis of the author's own experience and after critical evaluation of the relevant literature. Most important are: 1) Establishment of a comprehensive working anamnesis with special regard to specific features of the job, exposure patterns, and all working materials; 2) assessment of the hepatotoxic potential of the suspected working material according to the present state of knowledge in working medicine and toxicology; 3) objectification and quantification of the suspected noxious substances at the place of work by means of air analysis and analysis of the biological matter; 4) differential diagnosis in view of possible competitive influencing factors.

    A growing body of literature indicates that the natural course of multiple sclerosis can be influenced by a number of factors. Strong evidence suggests that relapses can be triggered by infections, the postpartum period and stressful life events. Vaccinations against influenza, hepatitis B and tetanus appear to be safe. Surgery, general and epidural anaesthesia, and physical trauma are not associated with an increased risk of relapses. Factors that have been associated with a reduced relapse rate are pregnancy, exclusive breastfeeding, sunlight exposure and higher vitamin D levels. A number of medications, including hormonal fertility treatment, seem to be able to trigger relapses. Factors that may worsen progression of disability include stressful life events, radiotherapy to the head, low levels of physical activity and low vitamin D levels. Strong evidence suggests that smoking promotes disease progression, both clinically and on brain magnetic resonance imaging. There is no evidence for an increased progression of disability following childbirth in women with multiple sclerosis. Moderate alcohol intake and exercise might have a neuroprotective effect, but this needs to be confirmed. PMID:20483884

    This document is the final report for the NASA/Langley contract entitled 'Perceptual Factors that Influence Use of Computer Enhanced Visual Displays.' The document consists of two parts. The first part contains a discussion of the problem to which the grant was addressed, a brief discussion of work performed under the grant, and several issues suggested for follow-on work. The second part, presented as Appendix I, contains the annual report produced by Dr. Ann Fulop, the Postdoctoral Research Associate who worked on-site in this project. The main focus of this project was to investigate perceptual factors that might affect a pilot's ability to use computer generated information that is projected into the same visual space that contains information about real world objects. For example, computer generated visual information can identify the type of an attacking aircraft, or its likely trajectory. Such computer generated information must not be so bright that it adversely affects a pilot's ability to perceive other potential threats in the same volume of space. Or, perceptual attributes of computer generated and real display components should not contradict each other in ways that lead to problems of accommodation and, thus, distance judgments. The purpose of the research carried out under this contract was to begin to explore the perceptual factors that contribute to effective use of these displays.

  2. Factors influencing teaching style in block-scheduled science classrooms

    Schoen Giddings, Linda

    This survey study sought to determine the extent to which teachers' personal belief systems, the leadership practices of the principal, and the nature of the organization as a professional learning community influence their teaching methodologies. The data were contributed by 172 South Carolina science teachers from 65 4 x 4 block-scheduled high schools. The teachers were pre-identified by teaching style as predominantly constructivist or traditional. The online survey consisted of two parts. Part I was the CTBA (Torff & Warburton 2005), which examined teacher beliefs regarding critical-thinking classroom strategies. Part II was the short form of the LOLSO Project Questionnaires (Shins et al., 2002), which examined teacher perceptions of their principal as a transformational leader and of their school as a learning organization. Logistic regression analysis identified two significant factors differentiating constructivist and traditional teachers. Traditional teachers were more likely to believe that low critical-thinking strategies were appropriate strategies for use in the classroom and constructivist teachers were more likely to perceive their schools as learning organizations. These two factors, when entered into the logistic regression predictive equation, could predict group membership with a 61% accuracy level. While not a differentiating factor, there was also a strong correlation between leadership and organizational learning (r = .86). These findings are consistent with other research that has found that schools which are learning organizations support more constructivist pedagogy and student-centered classrooms and are dependent upon strong support from school leadership.

  3. Pneumonitis after radiotherapy of lung cancer - incidence and influencing factors

    International Nuclear Information System (INIS)

    Background: The most important side effect in radiotherapy of lung cancer is pneumonitis. The incidence of pneumotitis was evaluated in a retrospective study in the patient collective of the University of Heidelberg. Therapy related and therapy independent factors have been evaluated. Results: Regarding the treatment prior to irradiation patients with primary irradiation were affected in 26.5% (17% slight, 9.5% severe), with postoperative irradiation in 14% (9.3% slight, 4.7% severe), with radiochemotherapy of small cell lung cancer (SCLC) in 15.4% (12% slight, 3.4% severe) by this side effect. These differences were not significant (p=0.32). The median onset of pneumonitis was 31 days after end of irradiation (severe 23 days, slight 44 days, p=0.026). By a univariate analysis the total dose at the prescription point was the most important factor (30 to 50.5 Gy 11%, 52 to 59 Gy 15%, 60 to 74 Gy 26%, p=0.007). High single doses (2.5 Gy) were only applied within a study of radiochemotherapy with a randomised sequential and alternating schedule. So that the increased rate of pneumonitis (42%) is not clearly separable from other influencing variables. A correlation between the applied techniques and the irradiated volume (measured by planimetric methods) was not demonstrable. Regarding the independent factors a high age, female sex and a low FeV1 were unfavourable. However, age and sex corrected FeV1 was not predictive. (orig./AJ)

    Full Text Available The purpose of this research was to identify the factors upon which museum sustainability depends and the way in which this can be measured. Methodologically, we applied a qualitative research approach, using semi-structured interviews with experts from the Romanian museum sector, complemented by an in-depth study of the literature in this field. Results indicated that any objective measuring of sustainability must take into account the size of a museum’s collections and its organizational structure. It was also found that museum type can affect sustainability via its competitive advantage. However, the sustainability of a museum is not strictly determined by these factors, but also by the management and marketing strategies applied. Based on analysis of literature- and respondent-based factors influencing sustainability, this article proposes a set of 33 indicators that can be used by museums to measure their sustainability, as well as a model that enables evaluation of the sustainability levels of various museums comparatively, regardless of their type, size or importance (e.g., national, regional and local. The results obtained are useful both from a theoretical point of view, given that there are few writings on this topic, and from a practical point of view, as they provide a basis for a clear, objective model of museum sustainability measurement.

  8. Factors influencing the surface quality of polished tool steels

    International Nuclear Information System (INIS)

    Today’s demands on surface quality of moulds for injection moulding of plastic components involve no/low defect contents and roughness levels in the nm-range for high gloss applications. Material properties as well as operating conditions influence the mould finish, and thus the final surface of moulded products. This paper focuses on how particle content and different polishing strategies influence final surface qualities of moulds. Visual estimations of polished tool steel samples were combined with non-contact 3D-surface texture analysis in order to correlate traditional assessments to more quantitative methods, and to be able to analyse the surfaces at nanometre-level. It was found that steels with a lower proportion of particles, like carbides and oxides, gave rise to smoother polished surfaces. In a comparative study of polishers from different polishing shops, it was found that while different surface preparation strategies can lead to similar final roughness, similar preparation techniques can produce high-quality surfaces from different steel grades. However, the non-contact 3D-surface texture analysis showed that not all smooth polished surfaces have desirable functional topographies for injection moulding of glossy plastic components. (paper)

    The aim of this research was to identify factors associated with mothers breast feeding and to identify, for those who breast fed, factors associated with breast feeding for as long as planned. BACKGROUND: breast-feeding rates in Ireland are amongst the lowest in Europe. Research evidence indicates that in order for mothers to be successful at breast feeding, multiplicities of supports are necessary for both initiation and duration. The nature of these supports in tandem with other influencing factors requires analysis from an Irish perspective. DESIGN: cross-sectional study involving public health nurses and mothers in Ireland. This paper presents the results of the mothers\\' evaluation. METHOD: mothers (n=1715) with children less than three years were offered a choice of completing the self-report questionnaires online or by mail. Data were analysed and reported using descriptive and inferential statistics. FINDINGS: four in every five participants breast fed their infant and two thirds of them breast fed as long as planned. The multivariate logistic regression analysis identified that third level education, being a first time mother or previously having breast fed, participating online, having more than two public health nurse visits, and having a positive infant feeding attitude were independently and statistically significantly associated with breast feeding. Among mothers who breast fed, being aged at least 35 years, participating online, having a positive infant feeding attitude and high breast-feeding self-efficacy were independently and statistically significantly associated with breast feeding for as long as planned. CONCLUSIONS: findings from this study reinforce health inequalities therefore there needs to be a renewed commitment to reducing health inequalities in relation to breast feeding. RELEVANCE TO CLINICAL PRACTICE: this study has identified factors associated with initiation and duration of breast feeding that are potentially modifiable through

    Pathogens can have a negative influence on dendritic cells (DCs), causing their apoptosis, which prevents active presentation of foreign antigens. It results in a state of immunosuppression which makes the body susceptible to secondary infections. Infected immature DCs have lower expression of co-stimulatory and adhesion molecules, reduced ability to secrete cytokines and an inhibited maturation process and are incapable of effective antigen presentation and activation of T-lymphocytes. In some cases, the ability of DCs to undergo rapid apoptosis is important for the body defense, which is probably because of DCs' ability to cross-present and cooperate with other cells. Apoptotic bodies released from the infected DCs are phagocytosed by other DCs, which then stimulate the effector cells and present antigens more efficiently than infected cells. The aim of this article is to review how the DCs respond to viral and bacterial factors and which biochemical mechanisms are responsible for their apoptosis. PMID:26528349

    This study employed a community-based participatory research approach to understand factors that influence church readiness to engage in HIV prevention and treatment activities. A convenience sample of twenty-six Black faith leaders participated in four focus groups. Data analysis was done through qualitative content analysis. Three themes emerged. First, the pastor's blessing and authority as the church's decision-maker determines readiness to engage in HIV prevention. Second, the church's purview of sexual health as part of a holistic ministry facilitates faith leader's readiness. Lastly, securing financial and human resources makes it feasible for faith leaders to implement activities. Findings suggest HIV-related stigma alone does not explain readiness to address HIV. Participants also discussed activities their churches are equipped to handle, including HIV testing events and health fairs. PMID:26345680

    Full Text Available We estimated the geographic distributions of triatomine species in Central-West Region of Brazil (CW and analysed the climatic factors influencing their occurrence. A total of 3,396 records of 27 triatomine species were analysed. Using the maximum entropy method, ecological niche models were produced for eight species occurring in at least 20 municipalities based on 13 climatic variables and elevation. Triatoma sordida and Rhodnius neglectus were the species with the broadest geographic distributions in CW Brazil. The Cerrado areas in the state of Goiás were found to be more suitable for the occurrence of synanthropic triatomines than the Amazon forest areas in the northern part of the state of Mato Grosso. The variable that best explains the evaluated models is temperature seasonality. The results indicate that almost the entire region presents climatic conditions that are appropriate for at least one triatomine species. Therefore, it is recommended that entomological surveillance be reinforced in CW Brazil.

    Methods: Data were collected by interviews with 170 Czech men aged between 25 and 50. Grounded theory approach was used to generate new related theoretical ideas. Results: The present young men leave the decision rather up to women. A number of young men enter a relationship assuming automatically that their partner uses hormonal contraception. Family planning decision-making is influenced by personal values as well as structural factors. Strong social pressure determining the ideal form of material and psycho-social background for offspring confronts current generation with very demanding decision-making on parenthood timing. Conclusions: In men's opinion, the setting of conditions for the beginning of reproduction should be the result of negotiation within the couple. Although men speak of the need to negotiate, the responsibility and practical decision-making is left up mainly to women. [Int J Reprod Contracept Obstet Gynecol 2014; 3(4.000: 880-886

    Full Text Available Packaging is an important instrument of commerce and trade in the world, it plays essential role in increasing sales and export and thus it maximizes profits generated in enterprises. Hence, the appropriate packaging for the producer generates necessary incentives for production, partly preserves them against zany opponents, and finally provides the customer with much more variety and choosing the right products. Packaging in fact, is a major contributor to the performance of customer relationship management. This survey determines five packaging factors influencing on export development including communications, infrastructure, awareness, design and technical extraction. Through the implementation of principal component analysis, the effective role of packaging components on exports is measured. Exploratory research model indicates that all five packing components were effective in export development of food industry.

    Full Text Available David Barrett,1 Jonathan Thorpe,2 Nick Goodwin3 1Faculty of Health and Social Care, 2Knowledge Exchange, University of Hull, Hull, 3International Foundation for Integrated Care, Oxford, UK Abstract: Telecare, or the use of remote care technologies to support safe and independent living, offers great potential to mitigate the challenges faced in a time of changing demographics. By supporting people to live for longer in their own home, telecare can enhance quality of life, reduce reliance on institutional care settings, and reduce costs. Despite these potential opportunities, the adoption of telecare has not been as fast or widespread as it might have been. This article discusses some of the factors acting as drivers or barriers, which have influenced adoption and impacted on implementation. The implications of the availability of such a wide range of telecare applications is explored; this diversity of choice allows for services to be tailored to the specific needs of users, but also causes a tangled web of terminology that can lead to confusion and lack of clarity. In terms of the evidence base, although evaluations of telecare services often demonstrate a high level of cost benefit and user satisfaction, primary research findings are not as positive. This paper focuses particularly on the Whole System Demonstrator, a large-scale, randomized controlled trial that raised questions about the value and cost-effectiveness of telecare. The paper also discusses the ethical, governance, and resource issues associated with telecare implementation and the organizational complexities inherent in such exciting but challenging changes to services. The policy perspective is also summarized, highlighting how much of the adoption of telecare to date has been influenced by top-down initiatives. Telecare will continue to evolve as our understanding and the technology continue to develop. This paper provides information and advice for commissioners, providers

    The orifice plate energy dissipater is an economic and highly efficient dissipater.However,there is a risk of cavitaion around the orifice plate flow.In order to provide references for engineering practice,we examined the cavitation mechanism around the orifice plate and its influencing factors by utilizing mathematical analysis methods to analyze the flow conditions around the orifice plate in view of gas bubble dynamics.Through the research presented in this paper,the following can be observed:The critical radius and the critical pressure of the gas nucleus in orifice plate flow increase with its initial state parameter τ0;the development speed of bubbles stabilizes at a certain value after experiencing a peak value and a small valley value;and the orifice plate cavitation is closely related to the distribution of the gas nucleus in flow.For computing the orifice plate cavitation number,we ought to take into account the effects of pressure fluctuation.The development time of the gas nucleus from the initial radius to the critical radius is about10-7-10-5 s;therefore,the gas nucleus has sufficient time to develop into bubbles in the negative half-cycle of flow fluctuation.The orifice critical cavitation number is closely related to the orifice plate size,and especially closely related with the ratio of the orifice plate radius to the tunnel radius.The approximate formula for the critical cavitation number of the square orifice plate that only considers the main influencing factor was obtained by model experiments.

    Full Text Available Purpose: To determine the factors that influence the surgical success in patients with infantile esotropia and to evaluate the relationship between amount of bilateral medial rectus recession and convergence. Material and Method: We retrospectively investigated the records of 188 patients with infantile esotropia who were operated on. The surgical success rate, the factors that influence the surgical success, and the relationship between amount of bilateral medial rectus recession and convergence deficiency were evaluated. Successful outcome was defined as deviation amount lower than 10 prism diopters postoperatively. Results: The mean age of the 188 patients included in the study at presentation was 54.9±56.8 (5-276 months, and the mean surgical age was 60.7±54.8 (7-276 months. Success was provided in 70.7% of patients after the first surgery and in 86.7% of patients after repeated surgeries. It was seen that gender, surgical age, refractive error, surgical procedure and the presence of fusion before surgery did not affect surgical success. Residual esotropia was found more frequently in patients with large-angle preoperative deviation, whilst both residual esotropia and consecutive exotropia were found more frequently in patients with amblyopia. It was observed that augmented bilateral medial rectus recession did not cause an increase in postoperative convergence deficiency. Discussion: Since the presence of amblyopia affects the surgical success negatively, it must be identified and treated preoperative. Residual esotropia is more frequently seen in patients with large-angle deviation preoperative, and more than one surgery may be required to provide orthophoria. In these cases, augmented bilateral medial rectus recession is a safe and effective method that rescues the patient from repeated surgeries and may be preferred to three-or four-muscle surgeries.

  19. Study on influencing factors for hydrogen isotopic exchange

    International Nuclear Information System (INIS)

    Background: Hydrogen-water catalytic exchange reaction offers an approach to hydrogen isotope separation, which can be applied in heavy water detritiation. Purpose: To optimize the operating condition for hydrogen-water catalytic exchange reaction, we analysed the influence of different factors on the transfer coefficient. Methods: In detail, the isotope exchange experiments of H-D system were carried out in a self-designed catalytic bed loaded with hydrophobic catalyst and hydrophilic packing with certain volume ratio. The experiments showed the changes of both the transfer coefficient and the pressure drop of column with the changing of the operational temperatures (29℃, 45℃, 60℃ and 75℃), the ratios of gas to liquid (0.58, 1.17, 2.65, 3.54) and the deuterium concentrations (5.05×10-3, 1.0144×10-2, 2.01×10-2). Results: Results showed that 45℃ is the optimal temperature for operating. The transfer coefficient increases with the increasing of the ratio of gas to liquid in the ranges of 0.58 to 1.17 and 2.65 to 3.56, while decreases with the deuterium concentration increases from 5.05×10-3 to 2.01×10-2. The pressure drop of column increases with increasing of gas flow rate. Conclusions: The experiment proves that the ratio of gas to liquid, the reaction temperature and the deuterium concentration are all important factors, which influence the transfer coefficient of deuterium obviously. The optimal operating condition for hydrogen-water catalytic exchange reaction are as follows: the temperature is 45℃, the ratio of gas to liquid is 3.56, and the deuterium concentration is 2.01×10-2.

    Full Text Available OBJECTIVE: Tactile explorations with the fingertips provide information regarding the physical properties of surfaces and their relative pleasantness. Previously, we performed an investigation in the active touch domain and linked several surface properties (i.e. frictional force fluctuations and net friction with their pleasantness levels. The aim of the present study was to investigate physical factors being important for pleasantness perception during passive fingertip stimulation. Specifically we were interested to see whether factors, such as surfaces' topographies or their frictional characteristics could influence pleasantness. Furthermore, we ascertained how the stimulus pleasantness level was impacted by (i the normal force of stimulus application (FN and (ii the stimulus temperature (TS. METHODS AND RESULTS: The right index fingertips of 22 blindfolded participants were stimulated using 27 different stimuli, which varied in average roughness (Ra and TS. A 4-axis robot moved the stimuli horizontally under participants' fingertips with three levels of FN. The robot was equipped with force sensors, which recorded the FN and friction force (FT during stimulation. Participants rated each stimulus according to a three-level pleasantness scale, as very pleasant (scored 0, pleasant (scored 1, or unpleasant (scored 2. These ordinal pleasantness ratings were logarithmically transformed into linear and unidimensional pleasantness measures with the Rasch model. Statistical analyses were conducted to investigate a possible link between the stimulus properties (i.e. Ra, FN, FT, and TS and their respective pleasantness levels. Only the mean Ra and FT values were negatively correlated with pleasantness. No significant correlation was detected between FN or TS and pleasantness. CONCLUSION: Pleasantness perception, resulting from passive fingertip stimulation, seems to be influenced by the surfaces' average roughness levels and average FT occurring
