Belgian hospitals face a growing shortage of physicians and increasingly competitive market conditions. In this challenging environment hospitals are struggling to build effective hospital-physician relationships which are considered to be a critical determinant of organizational success. Employed physicians of a University hospital were surveyed. Organizational attributes were identified through the literature and two focus groups. Variables were measured using validated questionnaires. Descriptive analyses and linear regression were used to test the model and relative importance analyses were performed. The selected attributes predict hospital attractiveness significantly (79.3%). The relative importance analysis revealed that hospital attractiveness is most strongly predicted by professional attributes (35.3%) and relational attributes (29.7%). In particular, professional development opportunities (18.8%), hospital prestige (16.5%), organizational support (17.2%) and leader support (9.3%) were found to be most important. Besides these non-economic aspects, the employed physicians indicated pay and financial benefits (7.4%) as a significant predictor of hospital attractiveness. Work-life balance and job security were not significantly related to hospital attractiveness. This study shows that initiatives aimed at strengthening physicians' positive perceptions of professional and relational aspects of practicing medicine in hospitals, while assuring satisfactory financial conditions, may offer useful avenues for increasing the level of perceived hospital attractiveness. Overall, hospitals are advised to use a differentiated approach to increase their attractiveness to physicians.

Structure loss to wildfire is a serious problem in wildland-urban interface areas across the world. Laboratory experiments suggest that fire-resistant building construction and design could be important for reducing structure destruction, but these need to be evaluated under real wildfire conditions, especially relative to other factors. Using empirical data from destroyed and surviving structures from large wildfires in southern California, we evaluated the relative importance of building construction and structure age compared to other local and landscape-scale variables associated with structure survival. The local-scale analysis showed that window preparation was especially important but, in general, creating defensible space adjacent to the home was as important as building construction. At the landscape scale, structure density and structure age were the two most important factors affecting structure survival, but there was a significant interaction between them. That is, young structure age was most important in higher-density areas where structure survival overall was more likely. On the other hand, newer-construction structures were less likely to survive wildfires at lower density. Here, appropriate defensible space near the structure and accessibility to major roads were important factors. In conclusion, community safety is a multivariate problem that will require a comprehensive solution involving land use planning, fire-safe construction, and property maintenance.

As the most severe ecological issue in southwest China, karst rocky desertification (KRD) has both threatened and constrained regional sustainable development. Comprehensively understanding the relationship between the evolution of KRD and relevant driving data would provide more information to combat KRD in such complex karst environments. Past studies have been limited in quantifying the relative importance of driving factors influencing fine-scale KRD evolution, and have also lacked insight into their interactive impacts. To address these issues, we have used geographical information system techniques and a geographical detector model to explore the spatial consistency of driving factors and their interactions in relation to the evolution of KRD. Changshun County in China was selected as a representative area for the study. Nine relevant driving factors, including both natural and anthropogenic factors, were studied in regard to their relationships with KRD transformation between 2000 and 2010. Our results demonstrate the relative importance of driving data in influencing the improvement and deterioration of KRD. Lithology, soil type and road influence are identified as the leading factors. Interestingly, to our study at least, there is no significant difference between the impacts of natural and anthropogenic factors influencing KRD improvement, and even natural factors have a higher impact on KRD deterioration. Factors were found to enhance the influence of each other for KRD transformation. In particular, the results show a non-linearly enhanced effect between driving factors, which significantly aggravates KRD. New information found in our study helps to effectively control and restore areas afflicted by KRD.

The current European Union (EU) legislation decrees that pets entering the EU from a rabies-infected third country have to obtain a satisfactory virus-neutralizing antibody level, while those moving within the EU require only rabies vaccination as the risk of moving a rabid pet within the EU is considered negligible. A number of factors driving individual variations in dog vaccine response have been previously reported, including a high rate of vaccine failure in puppies, especially those subject to commercial transport. A total of 21 001 observations collected from dogs (2006-2012) vaccinated in compliance with the current EU regulations were statistically analysed to assess the effect of different risk factors related to rabies vaccine efficacy. Within this framework, we were able to compare the vaccination failure rate in a group of dogs entering the Italian border from EU and non-EU countries to those vaccinated in Italy prior to international travel. Our analysis identified that cross-breeds and two breed categories showed high vaccine success rates, while Beagles and Boxers were the least likely to show a successful response to vaccination (88.82% and 90.32%, respectively). Our analysis revealed diverse performances among the commercially available vaccines, in terms of serological peak windows, and marked differences according to geographical area. Of note, we found a higher vaccine failure rate in imported dogs (13.15%) than in those vaccinated in Italy (5.89%). Our findings suggest that the choice of vaccine may influence the likelihood of an animal achieving a protective serological level and that time from vaccination to sampling should be considered when interpreting serological results. A higher vaccine failure in imported compared to Italian dogs highlights the key role that border controls still have in assessing the full compliance of pet movements with EU legislation to minimize the risk of rabies being reintroduced into a disease-free area. �

Objectives. We isolated physical activity attributable to transit use to examine issues of substitution between types of physical activity and potential confounding of transit-related walking with other walking. Methods. Physical activity and transit use data were collected in 2008 to 2009 from 693 Travel Assessment and Community study participants from King County, Washington, equipped with an accelerometer, a portable Global Positioning System, and a 7-day travel log. Physical activity was classified into transit- and non–transit-related walking and nonwalking time. Analyses compared physical activity by type between transit users and nonusers, between less and more frequent transit users, and between transit and nontransit days for transit users. Results. Transit users had more daily overall physical activity and more total walking than did nontransit users but did not differ on either non–transit-related walking or nonwalking physical activity. Most frequent transit users had more walking time than least frequent transit users. Higher physical activity levels for transit users were observed only on transit days, with 14.6 minutes (12.4 minutes when adjusted for demographics) of daily physical activity directly linked with transit use. Conclusions. Because transit use was directly related to higher physical activity, future research should examine whether substantive increases in transit access and use lead to more physical activity and related health improvements.

General relativity and gauge gravity theories of higher order

International Nuclear Information System (INIS)

Konopleva, N.P.

1998-01-01

It is a short review of today's gauge gravity theories and their relations with Einstein General Relativity. The conceptions of construction of the gauge gravity theories with higher derivatives are analyzed. GR is regarded as the gauge gravity theory corresponding to the choice of G ∞4 as the local gauge symmetry group and the symmetrical tensor of rank two g μν as the field variable. Using the mathematical technique, single for all fundamental interactions (namely variational formalism for infinite Lie groups), we can obtain Einstein's theory as the gauge theory without any changes. All other gauge approaches lead to non-Einstein theories of gravity. But above-mentioned mathematical technique permits us to construct the gauge gravity theory of higher order (for instance SO (3,1)-gravity) so that all vacuum solutions of Einstein equations are the solutions of the SO (3,1)-gravity theory. The structure of equations of SO(3,1)-gravity becomes analogous to Weeler-Misner geometrodynamics one

EFFECTS OF HIGHER EDUCATION ON GLOBAL COMPETITIVENESS: REVIEWS IN RELATION WITH EUROPEAN COUNTRIES AND THE MIDDLE EAST COUNTRIES

Directory of Open Access Journals (Sweden)

HILAL YILDIRIR KESER

2015-03-01

Full Text Available The aim of this study is investigate the effects of higher education on global competitiveness One of the most widely accepted definition of global competitiveness is in the form of " efficiency level encompassing all of the institutions that will ensure sustainable growth in a country, policies and factors of production". Therefore the competitiveness of a country depends on the factors such as; The level of development of R & D activities and productivity, performance of various sectors, the country's trade surplus, producing goods hosting high-tech in their nature, availability of expert and skilled labor force. But one of the main points in the realization of these factors is the quality of the higher education. Higher education has an important role in the formation of qualified labour. And the qualified labour carries the competitiveness firstly of the sector and then of the country up to higher ranks by increasing the performance and productivity of the companies. The study will be discussed in the following way: firstly the context of the global competitiveness will be mentioned, secondly, the role and importance of higher education will be put forth by explaining the basic determinants of competitivenes particularly within the World Economic Forum Global Competitiveness Index. Finally, assessments will be made in relation with the situation of higher education in global competitiveness in European countries and Middle Eastern countries.

Relative importance of the determinants of serum levels of 25-hydroxy vitamin D in patients with chronic kidney disease.

Science.gov (United States)

Caravaca-Fontán, Fernando; Gonzales-Candia, Boris; Luna, Enrique; Caravaca, Francisco

The cause of vitamin D deficiency in chronic kidney disease (CKD) is probably multi-factorial; however, the relative importance of each potential determinant is uncertain. To determine factors associated with serum levels of 25-hydroxy vitamin D (25OHD) and their relative importance in a cohort of pre-dialysis CKD patients. Incident patients admitted to a CKD outpatient clinic were included. Those who were receiving vitamin D supplements or anticonvulsants were excluded. In addition to demographic and clinical data, information about outdoor physical activity, season of blood collection, prescription of statins, anti-angiotensin drugs and xanthine-oxidase inhibitors were included as potential determinants. Johnson's relative weights analysis was used to estimate the relative importance of each potential determinant and the results were expressed as percentage contribution to multiple R. The study group consisted of 397 patients, 30 of whom were excluded. The mean serum level of 25OHD was 13.7±7.4ng/ml, and 81% of patients had serum levels lower than 20ng/ml. By multiple linear regression and relative weights analyses, the best determinants of low serum 25OHD levels and their relative importance were: higher proteinuria (28.5%), old age (21.4%), low physical activity (19.4%), female gender (19.3%) and low serum bicarbonate levels (11.4%). Proteinuria and age are the determinants with the highest relative importance for predicting 25OHD levels in CKD patients. Copyright © 2016. Published by Elsevier España, S.L.U.

The objective of this study was to explore oral health-related behavior, how patients with diabetes differ from patients not diagnosed with diabetes in their oral health and whether oral health-related behavior moderates the oral health status of patients with diabetes. Survey and chart review data were collected from 448 patients (52% male, 48% female, average age: 57 years) of which 77 were diagnosed with diabetes (17%). Patients with diabetes had a higher percentage of teeth with mobility than those not diagnosed with diabetes (14% vs. 8%, p=0.023), as well as gingival recession (16% vs. 12%, p=0.035) and more teeth with recession in the esthetic zone (1.17 vs. 0.88, p=0.046). They also had more decayed, missing and filled surfaces due to caries (101 vs. 82, pteeth due to caries (11 vs. 7, pbrushed and flossed less frequently. Patients with diabetes who did not brush regularly had poorer periodontal health (percentage of teeth with probing depth of teeth: 32% vs. 15%, p=0.033) than regularly brushing patients with diabetes. Educating patients with diabetes about the importance of good oral self care needs to become a priority for their oral health care providers.

McMahon, Camilla M.; Solomon, Marjorie

2015-01-01

Parent- and adolescent-report of social skill importance and social skill engagement on the Social Skills Rating System (Gresham & Elliott, 1990) were assessed in higher-functioning adolescents with Autism Spectrum Disorder (ASD). Compared to parents, adolescents reported that social skills were less important. Additionally, adolescents reported that they engaged in social skills more frequently than parents reported them to be engaging in social skills. Parents, but not adolescents, reported a discrepancy between importance and engagement, such that the importance of social skills was rated higher than the frequency of adolescent engagement in social skills. These results suggest that social skills interventions for individuals with ASD may need to target awareness of social skill importance and accurate monitoring of social skill engagement.

In a very influential paper, Piketty (2011) finds that inherited wealth is of increasing importance in France. He describes a U-shaped pattern in the long-run development of inheritance flows. Two driving factors in this development are the relative ratio of wealth of the deceased to wealth of the living, and the wealth-income ratio. In periods with high economic growth, wealth of the past is weakened and inheritances as share of national income decreases. As soon as growth declines, however,...

World governments have committed to increase the global protected areas coverage by 2020, but the effectiveness of this commitment for protecting biodiversity depends on where new protected areas are located. Threshold- and complementarity-based approaches have been independently used to identify important sites for biodiversity. We brought together these approaches by performing a complementarity-based analysis of irreplaceability in important bird and biodiversity areas (IBAs), which are sites identified using a threshold-based approach. We determined whether irreplaceability values are higher inside than outside IBAs and whether any observed difference depends on known characteristics of the IBAs. We focused on 3 regions with comprehensive IBA inventories and bird distribution atlases: Australia, southern Africa, and Europe. Irreplaceability values were significantly higher inside than outside IBAs, although differences were much smaller in Europe than elsewhere. Higher irreplaceability values in IBAs were associated with the presence and number of restricted-range species; number of criteria under which the site was identified; and mean geographic range size of the species for which the site was identified (trigger species). In addition, IBAs were characterized by higher irreplaceability values when using proportional species representation targets, rather than fixed targets. There were broadly comparable results when measuring irreplaceability for trigger species and when considering all bird species, which indicates a good surrogacy effect of the former. Recently, the International Union for Conservation of Nature has convened a consultation to consolidate global standards for the identification of key biodiversity areas (KBAs), building from existing approaches such as IBAs. Our results informed this consultation, and in particular a proposed irreplaceability criterion that will allow the new KBA standard to draw on the strengths of both threshold- and

Examination of the relative importance of hospital employment in non-metropolitan counties using location quotients.

Science.gov (United States)

Smith, Jon L

2013-01-01

The US Health Care and Social Services sector (North American Industrial Classification System 'sector 62') has become an extremely important component of the nation's economy, employing approximately 18 million workers and generating almost $753 billion in annual payrolls. At the county level, the health care and social services sector is typically the largest or second largest employer. Hospital employment is often the largest component of the sector's total employment. Hospital employment is particularly important to non-metropolitan or rural communities. A high quality healthcare sector serves to promote economic development and attract new businesses and to provide stability in economic downturns. The purpose of this study was to examine the intensity of hospital employment in rural counties relative to the nation as a whole using location quotients and to draw conclusions regarding how potential changes in Medicare and Medicaid might affect rural populations. Estimates for county-level hospital employment are not commonly available. Estimates of county-level hospital employment were therefore generated for all counties in the USA the Census Bureau's County Business Pattern Data for 2010. These estimates were used to generate location quotients for each county which were combined with demographic data to generate a profile of factors that are related to the magnitude of location quotients. The results were then used to draw inferences regarding the possible impact of the Patient Protection and Affordable Care Act 2010 (ACA) and the possible imposition of aspects of the Budget Control Act 2011 (BCA). Although a very high percentage of rural counties contain medically underserved areas, an examination of location quotients indicates that the percentage of the county workforce employed by hospitals in the most rural counties tends to be higher than for the nation as a whole, a counterintuitive finding. Further, when location quotients are regressed upon data

The relative importance of avoidance and restoration-oriented stressors for grief and depression in bereaved parents.

2015-01-01

Previous research has identified a number of individual risk factors for parental bereavement including the sex of the parent, the sex of the child, avoidance-focussed coping style and time since death. These factors emerged from research where variables were tested univariately and their relative importance is currently unknown. The current research, therefore, aims to investigate which risk factors are important, multivariately, for the outcomes of grief and depression in parents following the death of their child. Psychosocial measures were completed by 106 bereaved parents four years post-loss, recruited from death records in Scotland. The cause of the child's death included long-term illness and stillbirths as well as sudden and violent deaths. In multivariate regression analyses, depression was predicted by higher avoidance-focussed coping and higher number of restoration-oriented stressors such as relationship difficulties, problems at work and financial issues. Grief was predicted by higher avoidance, restoration stressors and level of continuing bonds. The present study adds to the knowledge about the phenomenon of parental bereavement with participants recruited directly from death records rather than through support, clinical or obituary sources. Factors previously found to be associated with outcomes when tested univariately such as sudden, violent death or sex of the parent were not significant when tested multivariately. This study highlights that different vulnerability factors exist for grief and depression in bereaved parents.

Lamu, Admassu N; Olsen, Jan Abel

2016-03-01

There is much evidence that health, income and social relationships are important for our well-being, but little evidence on their relative importance. This study makes an integrative analysis of the relative influence of health related quality of life (HRQoL), household income and social relationships for subjective well-being (SWB), where SWB is measured by the first three of the five items on the satisfaction with life scale (SWLS). In a comprehensive 2012 survey from six countries, seven disease groups and representative healthy samples (N = 7933) reported their health along several measures of HRQoL. A Shapley value decomposition method measures the relative importance of health, income and social relationships, while a quantile regression model tests how the effects of each of the three predictors vary across different points of SWB distributions. Results are compared with the standard regression. The respective marginal contribution of social relationships, health and income to SWB (as a share of goodness-of-fit) is 50.2, 19.3 and 7.3% when EQ-5D-5L is used as a measure of health. These findings are consistent across models based on five alternative measures of HRQoL. The influence of the key determinants varied significantly between low and high levels of the SWB distribution, with health and income having stronger influence among those with relatively lower SWB. Consistent with several studies, income has a significantly positive association with SWB, but with diminishing importance. Copyright © 2016 Elsevier Ltd. All rights reserved.

Full Text Available Mechanization and automation, swift communication and transport, computer usage and television viewing have reduced the need for vigorous occupations and discouraged involvement in leisure-time recreational activity. Studies have reported that there is a causal relationship between the risk of chronic disease incidence and mortality and physical activity and/or physical fi tness. Therefore, the aim of this review is to summarize and synthesize the association between health-related physical fi tness (aerobic endurance, fl exibility, strength/ endurance, body fat and chronic diseases. The papers reviewed demonstrate that higher and moderate levels of aerobic endurance, fl exibility, muscular strength/endurance, and desirable body fat levels, are very important for promoting health at all ages, and to avoid early development of chronic diseases. RESUMO A mecanização e a automação, o transporte e a comunicação rápidos, o uso do computador e da televisão têm diminuído atividades vigorosas, inclusive no tempo livre. Estudos reportam que a relação entre o risco de incidência de doenças crônico-degenerativas e a atividade física e/ou a aptidão física é causal. Portanto, o objetivo desta revisão é resumir e sintetizar a associação entre aptidão física relacionada à saúde (aptidão cardiorrespiratória, fl exibilidade, força/resistência muscular e gordura corporal e as doenças crônicodegenerativas. Os estudos mostram que altos e moderados níveis de aptidão cardiorrespiratória, fl exibilidade, força/resistência muscular, e um nível adequado de gordura são muito importantes para promover a saúde em todas idades, bem como evitar o desenvolvimento precoce de doenças crônico-degenerativas.

Farrell, Nicholas R; Deacon, Brett J

2016-03-01

Although client preferences are an integral component of evidence-based practice in psychology (American Psychological Association, 2006), relatively little research has examined what potential mental health consumers value in the psychotherapy they may receive. The present study was conducted to examine community members' preferences for the scientific and relational aspects of psychotherapy for different types of presenting problems, and how accurately therapists perceive these preferences. Community members (n = 200) were surveyed about the importance of scientific (e.g., demonstrated efficacy in clinical trials) and relational (e.g., therapist empathy) characteristics of psychotherapy both for anxiety disorders (e.g., obsessive-compulsive disorder) and disorder-nonspecific issues (e.g., relationship difficulties). Therapists (n = 199) completed the same survey and responded how they expected the average mental health consumer would. Results showed that although community members valued relational characteristics significantly more than scientific characteristics, the gap between these two was large for disorder-nonspecific issues (d = 1.24) but small for anxiety disorders (d = .27). Community members rated scientific credibility as important across problem types. Therapists significantly underestimated the importance of scientific characteristics to community members, particularly in the treatment of disorder-nonspecific issues (d = .74). Therapists who valued research less in their own practice were more likely to underestimate the importance of scientific credibility to community members. The implications of the present findings for understanding the nature of client preferences in evidence-based psychological practice are discussed. Copyright © 2015 Elsevier Ltd.

A relation between deformed superspace and Lee-Wick higher-derivative theories

Science.gov (United States)

Dias, M.; Ferrari, A. F.; Palechor, C. A.; Senise, C. R., Jr.

2015-07-01

We propose a non-anticommutative superspace that relates to the Lee-Wick type of higher-derivative theories, which are known for their interesting properties and have led to proposals of phenomenologically viable higher-derivative extensions of the Standard Model. The deformation of superspace we consider does not preserve supersymmetry or associativity in general, but, we show that a non-anticommutative version of the Wess-Zumino model can be properly defined. In fact, the definition of chiral and antichiral superfields turns out to be simpler in our case than in the well known N=1/2 supersymmetric case. We show that when the theory is truncated at the first nontrivial order in the deformation parameter, supersymmetry is restored, and we end up with a well-known Lee-Wick type of higher-derivative extension of the Wess-Zumino model. Thus, we show how non-anticommutativity could provide an alternative mechanism for generating these higher-derivative theories.

Full Text Available Relative importance is a topic that has seen a lot of interest in recent years, particularly in applied work. The R package relaimpo implements six different metrics for assessing relative importance of regressors in the linear model, two of which are recommended - averaging over orderings of regressors and a newly proposed metric (Feldman 2005 called pmvd. Apart from delivering the metrics themselves, relaimpo also provides (exploratory bootstrap confidence intervals. This paper offers a brief tutorial introduction to the package. The methods and relaimpo’s functionality are illustrated using the data set swiss that is generally available in R. The paper targets readers who have a basic understanding of multiple linear regression. For the background of more advanced aspects, references are provided.

Effects of competition on great and blue tit reproduction: intensity and importance in relation to habitat quality.

Science.gov (United States)

Dhondt, André A

2010-01-01

1. In studies on the effect of competition in plant communities two terms are used to describe its effects: the absolute reduction in growth of an individual as a consequence of the presence of another one is called intensity, while the relative impact of competition on an individual as a proportion of the impact of the whole environment is called importance. One school of thought is that the role of competition remains constant across productivity gradients, while the other is that it decreases with increasing severity. J.B. Grace (1991. A clarification of the debate between grime and tilman. Functional Ecology, 5, 583-587.) suggested that the apparent contradiction might be solved if we acknowledge that the two schools are discussing different aspects of competition: the intensity of competition might remain constant while its importance declines with increasing severity. 2. There are no studies that compare intensity and importance of competition in bird populations between areas that differ in quality or productivity and hence it is not possible to make predictions how intensity or importance of competition would vary between them. 3. I compared variation in intensity and importance of competition of three demographic variables between five plots that differ strongly in quality for great Parus major L. and blue tit Cyanistes caeruleus (L.). 4. Both intensity and importance of competition are larger in great than in blue tit populations meaning that the effect of competition on demographic variables is stronger in great than in blue tits and that the contribution of competition to variation in these variables is relatively higher in great than in blue tits. 5. Intensity of competition is higher in low quality than in high quality plots for both species, a result not expected from studies in plant communities. 6. Importance of competition varies strongly between plots. It is larger in oak-dominated plots than in mixed deciduous plots. 7. In birds breeding density

The relative importance of ingestion for multiple pathway dose assessments

International Nuclear Information System (INIS)

Wicker, W.; Grogan, H.; Bergstroem, U.; Hoffman, O.

1991-01-01

The general purpose of this report is to examine the relative importance of ingestion pathways, and particularly food chain transport in overall dose assessment. The importance of ingestion pathways is examined for various release scenarios and radionuclides because the findings are expected to differ with circumstances. The degree to which contaminated food products contribute to the total dose will affect the importance of accuracy and uncertainty of food chain model predictions, which is the main thrust of the Biospheric Model Validation Study (BIOMOVS). This analysis requires that all modes of radiation exposure be examined, including inhalation, external exposure, and the various ingestion pathways. (2 figs., 2 tabs.)

Warden, Clyde A; Wu, Wann-Yih; Tsai, Dungchun

2006-06-01

The Elaboration Likelihood Model (ELM) uses central (more thoughtful) and peripheral (less thoughtful) routes of persuasion to maximize communication effectiveness. This research implements ELM to investigate the relative importance of different aspects of the user experience in online shopping. Of all the issues surrounding online shopping, convenience, access to information, and trust were found to be the most important. These were implemented in an online conjoint shopping task. Respondents were found to use the central route of the ELM on marketing messages that involved issues of minimizing travel, information access, and assurances of system security. Users employed the peripheral ELM route when considering usability, price comparison, and personal information protection. A descriptive model of Web-based marketing components, their roles in the central and peripheral routes, and their relative importance to online consumer segments was developed.

The aim of this study was to evaluate the importance of alcohol-dependent patients' emotional expressivity, alcohol-related expectations and socio-demographic factors for prediction of motivation to refuse alcohol consumption. The study sample consisted of 136 alcohol-dependent patients (100 men and 36 women) undergoing treatment in Kaunas center for addictive disorders. Only higher expression of negative alcohol-related expectations (std. beta=0.192, P=0.023), higher emotional impulse intensity (std. beta=0.229, P=0.021) and higher expression of positive emotional expressiveness (std. beta=0.021, P=0.020) as well as gender (std. beta=0.180, P=0.049), education (std. beta=-0.137, P=0.038) and alcohol dependency treatment conditions (members of support group after rehabilitation program) (std. beta=0.288, P=0.001; std. beta=0.608, P=0.001) were significant factors for predicting the different level of alcohol-dependent patients motivation to refuse alcohol consumption. Negative alcohol-related expectations, emotional impulse intensity and positive emotional expressiveness were significant even though quite weak triggers for alcohol-dependent patients' different level of motivation to refuse alcohol consumption. An assumption could be made that by changing these triggers it is possible to change addictive behavior. Copyright © 2014 Lithuanian University of Health Sciences.

2016-01-01

Background For students attending university courses, experiencing test anxiety (TA) dramatically impairs cognitive performance and success at exams. Whereas TA is a specific case of social phobia, emotional intelligence (EI) is an umbrella term covering interpersonal and intrapersonal skills, along with positive stress management, adaptability, and mood. In the present study, we tested the hypothesis that higher EI and lower TA are associated. Further, sex differences were explored. Method During an exam week, a total of 200 university students completed questionnaires covering sociodemographic information, TA, and EI. Results Higher scores on EI traits were associated with lower TA scores. Relative to male participants, female participants reported higher TA scores, but not EI scores. Intrapersonal and interpersonal skills and mood predicted low TA, while sex, stress management, and adaptability were excluded from the equation. Conclusion The pattern of results suggests that efforts to improve intrapersonal and interpersonal skills, and mood might benefit students with high TA. Specifically, social commitment might counteract TA. PMID:26834474

2010-08-01

Full Text Available In this article, we investigate what happened when, contrary to the typical isolation of faculty in higher education, a group of higher educators from various disciplines in a graduate school of education met regularly to discuss issues related to our teaching and social justice. More specifically, we explored the following research question: How does collaboration among higher educators from various disciplines shape their beliefs and practices of teaching for social justice? Over three years of collaboration and conversation, not only did we expand our own knowledge and understandings of notions of social justice, but we began to take important steps towards increasing our social justice actions in our teaching. This article explores our efforts to create a self-directed professional development group of higher educators and provides suggestions for similarly interested higher educators.

North, Jamie S; Hope, Ed; Williams, A Mark

We examined whether anticipation is underpinned by perceiving structured patterns or postural cues and whether the relative importance of these processes varied as a function of task constraints. Skilled and less-skilled soccer players completed anticipation paradigms in video-film and point light display (PLD) format. Skilled players anticipated more accurately regardless of display condition, indicating that both perception of structured patterns between players and postural cues contribute to anticipation. However, the Skill×Display interaction showed skilled players' advantage was enhanced in the video-film condition, suggesting that they make better use of postural cues when available during anticipation. We also examined anticipation as a function of proximity to the ball. When participants were near the ball, anticipation was more accurate for video-film than PLD clips, whereas when the ball was far away there was no difference between viewing conditions. Perceiving advance postural cues appears more important than structured patterns when the ball is closer to the observer, whereas the reverse is true when the ball is far away. Various perceptual-cognitive skills contribute to anticipation with the relative importance of perceiving structured patterns and advance postural cues being determined by task constraints and the availability of perceptual information.

Who are private alcohol importers in the Nordic countries?

Directory of Open Access Journals (Sweden)

Grittner Ulrike

2014-04-01

Full Text Available Aims - The high price of alcohol in the Nordic countries has been a long-standing policy to curb consumption, which has led consumers to importing alcohol from countries with lower prices. This paper seeks to develop a profile of alcohol importers in four Nordic countries. Methods - Cross-sectional data from general population surveys in Denmark (2003-2006, Norway (2004, Sweden (2003-2006 and Finland (2005-2006 were analysed by multiple logistic and linear regression. Independent variables included region, socio-demographics, drinking indicators and alcohol-related problems. Outcome variables were importer status and amount of imported alcohol. Results - People living in regions close to countries with lower alcohol prices were more often importers and imported higher amounts than people living in other regions. Higher educated persons were more likely to be importers, but the amounts imported were smaller than those by people with lower education. Persons with higher incomes were also more likely to be importers and they also imported larger amounts than people with lower incomes. In Sweden and Denmark regional differences of importer rates were more pronounced for persons of lower incomes. Age, risky single-occasion drinking, risky drinking and alcohol problems were positively related to the amounts of imported alcohol. Conclusions - Private importers in the Nordic countries are an integrated yet heavy drinking segment of society and do not appear to be located on the fringes of society

Oil vulnerability index of oil-importing countries

International Nuclear Information System (INIS)

Gupta, Eshita

2008-01-01

This paper assesses the relative oil vulnerability of 26 net oil-importing countries for the year 2004 on the basis of various indicators - the ratio of value of oil imports to gross domestic product (GDP), oil consumption per unit of GDP, GDP per capita and oil share in total energy supply, ratio of domestic reserves to oil consumption, exposure to geopolitical oil market concentration risks as measured by net oil import dependence, diversification of supply sources, political risk in oil-supplying countries, and market liquidity. The approach using the principal component technique has been adopted to combine these individual indicators into a composite index of oil vulnerability. Such an index captures the relative sensitivity of various economies towards developments of the international oil market, with a higher index indicating higher vulnerability. The results show that there are considerable differences in the values of individual indicators of oil vulnerability and overall oil vulnerability index among the countries (both inter and intraregional).

Domestic work and psychological distress--what is the importance of relative socioeconomic position and gender inequality in the couple relationship?

Directory of Open Access Journals (Sweden)

Lisa Harryson

Full Text Available The aim of this study was to investigate whether the relation between responsibility for domestic work and psychological distress was influenced by perception of gender inequality in the couple relationship and relative socioeconomic position.In the Northern Swedish Cohort, all pupils who studied in the last year of compulsory school in a northern Swedish town in 1981 have been followed regularly until 2007. In this study, participants living with children were selected (n = 371 women, 352 men. The importance of relative socioeconomic position and perception of gender inequality in the couple relationship in combination with domestic work for psychological distress was examined through logistic regression analysis.Two combinations of variables including socioeconomic position ('having less than half of the responsibility for domestic work and partner higher socioeconomic position' and 'having more than half the responsibility for domestic work and equal socioeconomic position' were related to psychological distress. There were also higher ORs for psychological distress for the combinations of having 'less than half of the responsibility for domestic work and gender-unequal couple relationship' and 'more than half the responsibility for domestic work and gender-unequal couple relationship'. Having a lower socioeconomic position than the partner was associated with higher ORs for psychological distress among men.This study showed that domestic work is a highly gendered activity as women tend to have a greater and men a smaller responsibility. Both these directions of inequality in domestic work, in combination with experiencing the couple relationship as gender-unequal, were associated with psychological distress There is a need for more research with a relational approach on inequalities in health in order to capture the power relations within couples in various settings.

Daniela Frison

2016-11-01

Full Text Available Within the framework of modernisation of higher education systems in Europe, universities are invited to go beyond a knowledge-based perspective focused on disciplinary approaches and to be more concentrated on encouraging generic skills to deal with today’s complex and unpredictable career paths. The literature about Work-Related Learning and Work-Integrated Learning offers evidence to research regarding contributions of work-related experiences to the development of generic skills. The first part of the article presents a literature review carried out following the matching among three main keywords: work-related learning, generic skills, and higher education. Resources focused on the integration/teaching of generic skills in formal curriculum or in co-curriculum work-related activities and they were collected in order to explore the link between work-related learning in higher education and the development of generic skills. The focus is to identify valuable considerations to improve teaching strategies and methods. The second part presents an Italian work-related experience developed within the course of “Organizational Intervention Research Methods,” which involved 22 master’s degree students. The work-related assignment will be described in addition to the content analysis process of the 22 collected texts and the findings about the development of generic skills.

Preparing students for higher education and careers in agriculture and related fields: An ethnography of an urban charter school

Science.gov (United States)

Henry, Kesha Atasha

This study explored the preparation of students for higher education and careers in agriculturally-related fields at an urban charter high school. The data were collected through interviews, observations, and field notes. The data were analyzed by qualitative methodology with phenomenology as the theoretical framework. Findings indicated that administrators thought it was important to incorporate agricultural science courses into urban school curricula. They stated that agricultural science courses gave urban students a different way of looking at science and helped to enhance the science and technology focus of the school. Further, agricultural science courses helped to break urban students' stereotypes about agriculture and helped to bring in more state funding for educational programs. However they thought that it was more challenging to teach agricultural science in urban versus rural schools and they focused more on Science, Technology, Engineering, and Mathematics (STEM) related careers. The students had mixed views about higher education and careers in agriculture. This was based on their limited knowledge and stereotypes about agricultural majors and career options. The students highlighted several key reasons why they chose to enroll in agricultural science courses. This included the benefits of dual science credits and the ability to earn an associate degree upon successful completion of their program. Students also loved science and appreciated the science intensive nature of the agricultural courses. Additionally, they thought that the agricultural science courses were better than the other optional courses. The results also showed that electronic media such as radio and TV had a negative impact on students' perceptions about higher education and careers in agriculturally-related fields. Conclusions and recommendations are presented.

THE PARTICULARITIES OF SERVICES AND THE IMPORTANCE OF MARKETING IN HIGHER EDUCATION

Directory of Open Access Journals (Sweden)

Emanuela Maria AVRAM

2014-12-01

Full Text Available The recent changes in higher education impose an increased usage of marketing in this field, because this is the path to a more profound understanding of consumers' needs and to identifying the correct market position of the higher education institution. Moreover, it is helpful in developing various study programmes which provide graduates with the necessary skills to successfully meet the requirements of the labour market. At the same time, the employment of marketing in the academic environment not only contributes to correctly informing the public as regards the education offer and the benefits of being the holder of an academic degree, but it also strengthens the academic image and reputation on the market. Results show that higher education encompasses the particularities of services, and therefore, the marketing activities should be adapted to this field. Furthermore, adopting marketing in current activities not only helps higher education institutions in elaborating some concrete actions of attracting quality students, but it also consolidates the academic image on the market.

Influence of contact definitions in assessment of the relative importance of social settings in disease transmission risk.

Directory of Open Access Journals (Sweden)

Kirsty J Bolton

Full Text Available BACKGROUND: Realistic models of disease transmission incorporating complex population heterogeneities require input from quantitative population mixing studies. We use contact diaries to assess the relative importance of social settings in respiratory pathogen spread using three measures of person contact hours (PCH as proxies for transmission risk with an aim to inform bipartite network models of respiratory pathogen transmission. METHODS AND FINDINGS: Our survey examines the contact behaviour for a convenience sample of 65 adults, with each encounter classified as occurring in a work, retail, home, social, travel or "other" setting. The diary design allows for extraction of PCH-interaction (cumulative time in face-face conversational or touch interaction with contacts--analogous to the contact measure used in several existing surveys--as well as PCH-setting (product of time spent in setting and number of people present and PCH-reach (product of time spent in setting and number of people in close proximity. Heterogeneities in day-dependent distribution of risk across settings are analysed using partitioning and cluster analyses and compared between days and contact measures. Although home is typically the highest-risk setting when PCH measures isolate two-way interactions, its relative importance compared to social and work settings may reduce when adopting a more inclusive contact measure that considers the number and duration of potential exposure events. CONCLUSIONS: Heterogeneities in location-dependent contact behaviour as measured by contact diary studies depend on the adopted contact definition. We find that contact measures isolating face-face conversational or touch interactions suggest that contact in the home dominates, whereas more inclusive contact measures indicate that home and work settings may be of higher importance. In the absence of definitive knowledge of the contact required to facilitate transmission of various

This study aimed to describe and to analyse the importance of educational level for controlled risk factors and health-related quality of life (HRQoL). This observational study was conducted in nine European countries (5632 patients in 249 practices). We compared patients with a low level of education (up to 9 years) with patients with a high level of education (>9 years), with regard to controlled cardiovascular disease risk factors and HRQoL. A multilevel approach was used for statistical analysis. Patients with a low level of education were older (P education, female gender, living as single, patient group (coronary heart disease patients) and the number of other conditions were negatively associated with HRQoL. A higher sum of controlled risk factors were positively associated with higher HRQoL in the whole sample (r = 0.0086, P educational-level groups (r = 0.0075, P = 0.038 in the low-level group and r = 0.0082, P = 0.001 in the high-level group). Patients with a lower educational level were more often females, singles, had a higher number of other conditions, a higher number of uncontrolled risk factors and a lower HRQoL. However, the higher the control of risk factors was, the higher the HRQoL was overall as well as in both educational-level groups. © The Author 2013.

Procrastination is the action of delaying or postponing something such as making a decision or starting or completing some tasks or activities. According to previous studies, students who have a strong tendency to procrastinate get low scores in their tests, resulting in poorer academic performance compared to those who do not procrastinate. This study aims to identify the procrastination factors in completing assignments among three groups of undergraduate students. The relative importance of procrastination factors was quantified by the relative importance index (RII) method prior to ranking. A multistage sampling technique was used in selecting the sample. The findings revealed that `too many works in one time' is one of the top three factors contributing to procrastination in all groups.

Family history is considered a risk factor for age-related macular degeneration (AMD). With the advent of effective therapy for the disease, the importance of family history merits further investigation. This study quantifies the risk associated with family history, first, by a case-control study of reported family history and, second, by examining the siblings of AMD cases. The authors recruited cases with advanced AMD, spouses and siblings. All subjects were carefully phenotyped. Clinical findings in the siblings were compared with spouses. Information about family history was collected. The ORs for reported family history of AMD were calculated. Analyses were adjusted for age, smoking and genotype. 495 AMD cases, 259 spouses and 171 siblings were recruited. The OR for AMD was 27.8 (CI 3.8 to 203.0; p=0.001) with a reported family history of an affected parent and 12.0 (CI 3.7 to 38.6; p<0.0001) with a history of an affected sibling. ORs adjusted for age and smoking were higher. Examination of siblings confirmed their increased risk with 23% affected by AMD and an OR of 10.8 (4.5 to 25.8; p<0.0001). Adjusting for age increased the OR to 16.1 (6.2 to 41.8). The risk of AMD is greatly increased by having an affected first-degree relative. Those at risk need to be made aware of this and AMD patients should advise siblings and children to seek prompt ophthalmological advice if they develop visual symptoms of distortion or reduced vision.

Atrophic gastritis of the corporal mucosa is a frequent cause of hypergastrinemia. Hypergastrinemia is implicated in colorectal cancer development. To assess whether hypergastrinemic atrophic gastritis is associated with a higher risk of neoplastic colorectal lesions. Among 441 hypergastrinemic atrophic gastritis patients, 160 who were aged >40 and underwent colonoscopy for anaemia, diarrhoea or colorectal cancer-screening were retrospectively selected. Each patient was age- and gender-matched with a normogastrinemic control with healthy stomach. Controls had colonoscopy, gastroscopy with biopsies and gastrin assessment. 160 hypergastrinemic atrophic gastritis patients and 160 controls were included. 28 atrophic gastritis patients and 36 controls had neoplastic colorectal lesions (p=0.33). Patients and controls did not differ for frequency of colorectal adenomas (10.6% vs. 13.1%, p=0.60) or cancer (6.9% vs. 9.4%, p=0.54). Hypergastrinemic atrophic gastritis was not associated with a higher probability of developing colorectal cancer (OR 1.03, 95% CI 0.34-3.16). Age >50 years (OR 3.86) but not hypergastrinemia (OR 0.61) was associated with colorectal cancer. Hypergastrinemic atrophic gastritis is not associated with higher risk for colorectal cancer. Atrophic gastritis-related hypergastrinemia is not associated with an increased risk of neoplastic colorectal lesions. Closer surveillance of colonic neoplasia in atrophic gastritis patients seems not appropriate. Copyright © 2012 Editrice Gastroenterologica Italiana S.r.l. Published by Elsevier Ltd.

Although research has advanced methods for clarifying factors that relate to customer satisfaction, they have not been embraced by leisure researchers. Using results from a survey of wild turkey hunters, we applied traditional and revised importance-performance (IPA/RIPA), importance-grid analysis (IGA), and penalty-reward-contrast analysis (PRCA) to examine how activity-specific factors influenced satisfaction. Results suggested differences between the explicit and implicit importance of factors related to turkey hunting. Opportunities to kill turkeys were explicitly rated as less important than seeing, hearing, or calling in turkeys, but opportunities for harvest had relatively higher levels of implicit importance. PRCA identified “calling turkeys in” and “hearing gobbling” as minimum requirements that cause dissatisfaction if not fulfilled, but do not provide satisfaction, whereas “seeing turkeys” and an “opportunity to kill a turkey” related to both satisfaction and dissatisfaction. RIPA, IGA, and PRCA could provide valuable insights about factors that may improve satisfaction for leisure participants.

Amniotic fluid represents an abundant source of multipotent stem cells, referred as broadly multipotent given their differentiation potential and expression of pluripotency-related genes. However, the origin of this broadly multipotent cellular fraction is not fully understood. Several sources have been proposed so far, including embryonic and extraembryonic tissues. In this regard, the ovine developmental model uniquely allows for direct comparison of fetal fluid-derived cells from two separate fetal fluid cavities, the allantois and the amnion, over the entire duration of gestation. As allantoic fluid mainly collects fetal urine, cells originating from the efferent urinary tract can directly be compared with cells deriving from the extraembryonic amniotic tissues and the fetus. This study shows isolation of cells from the amniotic [ovine amniotic fluid cells (oAFCs)] and allantoic fluid [ovine allantoic fluid cells (oALCs)] in a strictly paired fashion with oAFCs and oALCs derived from the same fetus. Both cell types showed cellular phenotypes comparable to standard mesenchymal stem cells (MSCs), with trilineage differentiation potential, and expression of common ovine MSC markers. However, the expression of MSC markers per single cell was higher in oAFCs as measured by flow cytometry. oAFCs exhibited higher proliferative capacities and showed significantly higher expression of pluripotency-related genes OCT4, STAT3, NANOG, and REX1 by quantitative real-time polymerase chain reaction compared with paired oALCs. No significant decrease of pluripotency-related gene expression was noted over gestation, implying that cells with high differentiation potential may be isolated at the end of pregnancy. In conclusion, this study suggests that cells with highest stem cell characteristics may originate from the fetus itself or the amniotic fetal adnexa rather than from the efferent urinary tract or the allantoic fetal adnexa.

Background Understanding the drivers of large-scale vegetation change is critical to managing landscapes and key to predicting how projected climate and land use changes will affect regional vegetation patterns. This study aimed to improve our understanding of the role, magnitude and spatial distribution of the key environmental factors driving vegetation change in southern African savanna, and how they vary across physiographic gradients. Methodology/Principal Findings We applied Dynamic Factor Analysis (DFA), a multivariate times series dimension reduction technique to ten years of monthly remote sensing data (MODIS-derived normalized difference vegetation index, NDVI) and a suite of environmental covariates: precipitation, mean and maximum temperature, soil moisture, relative humidity, fire and potential evapotranspiration. Monthly NDVI was described by cyclic seasonal variation with distinct spatiotemporal patterns in different physiographic regions. Results support existing work emphasizing the importance of precipitation, soil moisture and fire on NDVI, but also reveal overlooked effects of temperature and evapotranspiration, particularly in regions with higher mean annual precipitation. Critically, spatial distributions of the weights of environmental covariates point to a transition in the importance of precipitation and soil moisture (strongest in grass-dominated regions with precipitation950 mm). Conclusions/Significance We quantified the combined spatiotemporal effects of an available suite of environmental drivers on NDVI across a large and diverse savanna region. The analysis supports known drivers of savanna vegetation but also uncovers important roles of temperature and evapotranspiration. Results highlight the utility of applying the DFA approach to remote sensing products for regional analyses of landscape change in the context of global environmental change. With the dramatic increase in global change research, this methodology augurs well for

The purpose of this study was to assess the extent to which participation in a 12-month exercise program changed the degree of importance that older adults attached to physical activity. In addition, associations among changes in physical activity importance and health-related and psychosocial outcomes were examined. Community-dwelling older adults (N = 179) were recruited to participate in a 12-month exercise trial examining the association between changes in physical activity and fitness with changes in brain structure and psychological health. Participants were randomly assigned to a walking condition or a flexibility, toning, and balance condition. Physical, psychological, and cognitive assessments were taken at months 0, 6, and 12. Involvement in a 12-month exercise program increased the importance that participants placed on physical activity; this positive change was similar across exercise condition and sex. Changes in importance, however, were only associated with changes in physical health status and outcome expectations for exercise midway through the intervention. There were no significant associations at the end of the program. Regular participation in physical activity can positively influence the perceived importance of the behavior itself. Yet, the implications of such changes on physical activity-related outcomes remain equivocal and warrant further investigation.

HOW IMPORTANT IS MONEY AS AN INCENTIVE TO MOTIVATE EMPLOYEES IN HIGHER EDUCATION SECTOR? LITERATURE REVIEW

Directory of Open Access Journals (Sweden)

DORIN COSMA

2014-05-01

Full Text Available This paper studies the influence money has on motivating the work force which takes part on both dull and creative tasks. Through a review of the most important findings on the subject, economists’ and psychologists’ theories are presented and discussed. The paper shows how, notwithstanding their high attention received from the business environment in the past, the principal-agent and the price effect theories are being replaced lately with the self determination, psychological contract and reinforcement theories in the configuration process of work incentives. Specific advantages and disadvantages of the use of financial motivators for increasing work performance are further examined and a clear example of how money and more specifically their perception affects the employees’ motivation is given. The results of the study conclude that money has an important role as a hygienic factor in the work environment but they do not represent a panacea for inducing high work motivation and are not enough for assuring the overall success, whether that we are talking about repetitive or creative activities. The late ones are exemplified by the tasks specific to the higher education sector.

Relative importance of redox buffers GSH and NAD(P)H in age-related neurodegeneration and Alzheimer disease-like mouse neurons.

Ghosh, Debolina; Levault, Kelsey R; Brewer, Gregory J

2014-08-01

Aging, a major risk factor in Alzheimer's disease (AD), is associated with an oxidative redox shift, decreased redox buffer protection, and increased free radical reactive oxygen species (ROS) generation, probably linked to mitochondrial dysfunction. While NADH is the ultimate electron donor for many redox reactions, including oxidative phosphorylation, glutathione (GSH) is the major ROS detoxifying redox buffer in the cell. Here, we explored the relative importance of NADH and GSH to neurodegeneration in aging and AD neurons from nontransgenic and 3xTg-AD mice by inhibiting their synthesis to determine whether NADH can compensate for the GSH loss to maintain redox balance. Neurons stressed by either depleting NAD(P)H or GSH indicated that NADH redox control is upstream of GSH levels. Further, although depletion of NAD(P)H or GSH correlated linearly with neuron death, compared with GSH depletion, higher neurodegeneration was observed when NAD(P)H was extrapolated to zero, especially in old age, and in the 3xTg-AD neurons. We also observed an age-dependent loss of gene expression of key redox-dependent biosynthetic enzymes, NAMPT (nicotinamide phosphoribosyltransferase), and NNT (nicotinamide nucleotide transhydrogenase). Moreover, age-related correlations between brain NNT or NAMPT gene expression and NADPH levels suggest that these genes contribute to the age-related declines in NAD(P)H. Our data indicate that in aging and more so in AD-like neurons, NAD(P)H redox control is upstream of GSH and an oxidative redox shift that promotes neurodegeneration. Thus, NAD(P)H generation may be a more efficacious therapeutic target upstream of GSH and ROS. © 2014 The Authors. Aging Cell published by the Anatomical Society and John Wiley & Sons Ltd.

The Relative Importance of Language in Guiding Social Preferences Through Development.

Esseily, Rana; Somogyi, Eszter; Guellai, Bahia

2016-01-01

In this paper, we review evidence from infants, toddlers, and preschoolers to tackle the question of how individuals orient preferences and actions toward social partners and how these preferences change over development. We aim at emphasizing the importance of language in guiding categorization relatively to other cues such as age, race and gender. We discuss the importance of language as part of a communication system that orients infants and older children's attention toward relevant information in their environment and toward affiliated social partners who are potential sources of knowledge. We argue that other cues (visually perceptible features) are less reliable in informing individuals whether others share a common knowledge and whether they can be source of information.

Violence associated with combat-related posttraumatic stress disorder: The importance of anger.

Novaco, Raymond W; Chemtob, Claude M

2015-09-01

The importance of anger with regard to violence among veterans with combat-related PTSD has received little attention. We previously proposed that in PTSD the activation of threat-related cognitive networks strongly potentiates anger in a positive feedback loop and that inhibitory controls on aggression can be overridden when PTSD and anger activation are conjoined. We predicted that violence would be intensified when combat-related PTSD was conjoined with anger. We used the National Vietnam Veterans Readjustment Study (NVVRS) public use data set, selecting the male combat theater veterans, which entailed 1,200 from the main survey (Study 1) and 259 from the clinical interview component (Study 2). Anger indices were constructed from NVVRS variables. PTSD was assessed by continuous symptom scores and by clinical diagnostic measures. Conjoined anger and PTSD was associated with greatly increased violence. PTSD was not associated with violence in the absence of anger. This result was obtained using alternative measures of PTSD and of anger in both the main survey and the clinical interview component. These findings call for reconceptualizing the association of PTSD and violence. Concerted attention should be given to anger as a risk factor for violence in the assessment and treatment of combat-related PTSD, and as an important portal of entry for treatment.

The relative importance of rapid evolution for plant-microbe interactions depends on ecological context.

Science.gov (United States)

Terhorst, Casey P; Lennon, Jay T; Lau, Jennifer A

2014-06-22

Evolution can occur on ecological time-scales, affecting community and ecosystem processes. However, the importance of evolutionary change relative to ecological processes remains largely unknown. Here, we analyse data from a long-term experiment in which we allowed plant populations to evolve for three generations in dry or wet soils and used a reciprocal transplant to compare the ecological effect of drought and the effect of plant evolutionary responses to drought on soil microbial communities and nutrient availability. Plants that evolved under drought tended to support higher bacterial and fungal richness, and increased fungal : bacterial ratios in the soil. Overall, the magnitudes of ecological and evolutionary effects on microbial communities were similar; however, the strength and direction of these effects depended on the context in which they were measured. For example, plants that evolved in dry environments increased bacterial abundance in dry contemporary environments, but decreased bacterial abundance in wet contemporary environments. Our results suggest that interactions between recent evolutionary history and ecological context affect both the direction and magnitude of plant effects on soil microbes. Consequently, an eco-evolutionary perspective is required to fully understand plant-microbe interactions.

Perceived importance of sustainability and ethics related to fish: a consumer behavior perspective.

Verbeke, Wim; Vanhonacker, Filiep; Sioen, Isabelle; Van Camp, John; De Henauw, Stefaan

2007-11-01

Although sustainability and ethics are of increasing public importance, little research has been conducted to reveal its association with fish consumer behavior. Cross-sectional data were collected through a postal self-administered survey (June 2005) from a sample of 381 Flemish women aged 20-50 years. Consumers attach high perceived importance to sustainability and ethics related to fish. However, this perceived importance is neither correlated with fish consumption frequency nor with general attitude toward eating fish. Refusing to eat wild fish is grounded in sustainability and ethical concerns, whereas the decision not to eat farmed fish is associated with a lower expected intrinsic quality rather than shaped by importance attached to sustainability and ethical issues.

Psychological perceptions are increasingly being recognized as important to recovery and rehabilitation post-surgery. This research longitudinally examined perceptions of the personal importance of exercise and fears of re-injury over a three-year period post anterior cruciate ligament (ACL) reconstruction. Stability and change in psychological perceptions was examined, as well as the association of perceptions with time spent in different types of physical activity, including walking, household activities, and lower and higher risk for knee injury activities. Participants were athletes, 18-40 years old, who underwent ACL reconstruction for first-time ACL injuries. They were recruited from a tertiary care centre in Toronto, Canada. Participants completed interviewer-administered questionnaires pre-surgery and at years one, two and three, postoperatively. Questions assessed demographics, pain, functional limitations, perceived personal importance of exercise, fear of re-injury and physical activities (i.e., walking; household activities; lower risk for knee injury activities; higher risk for knee injury activities). Analyses included fixed-effect longitudinal modeling to examine the association of a fear of re-injury and perceived personal importance of exercise and changes in these perceptions with the total hours spent in the different categories of physical activities, controlling for other factors. Baseline participants were 77 men and 44 women (mean age = 27.6 years; SD = 6.2). At year three, 78.5% of participants remained in the study with complete data. Fears of re-injury decreased over time while personal importance of exercise remained relatively stable. Time spent in walking and household activities did not significantly change with ACL injury or surgery. Time spent in lower and higher risk of knee injury physical activity did not return to pre-injury levels at three years, post-surgery. Greater time spent in higher risk of knee injury activities

The prudent use of antimicrobials (AMs) should be widened in pig farming to reduce the risk of AM resistance (AMR) in human and veterinary medicine. It is therefore important to understand pig farmers' motivators and the barriers to AM usage (AMU) on their farms. The authors investigated pig farmers' self-estimated levels of AMU, their perceived benefits and risks and the need for AMs in a cross-sectional survey in Belgium, France, Germany and Sweden. The authors also compared these perceptions between the four countries and related them to pig farmers' actual AMU. The results showed that farmers who used more AMs also estimated their own usage as higher. Farmers perceived many benefits but relatively few risks of AMU in pig farming. Some significant cross-country differences in farmers' perceptions were found, but they were relatively small. After controlling for country differences and farm differences, only perceived risks had a significant association with AMU. The authors therefore conclude that in order to promote prudent AMU, it seems most promising to focus on the structural differences in pig farming and veterinary medicine (e.g. legislation, role of the veterinarian) among countries. In addition, interventions which aim at reducing AMU should increase farmers' awareness of the risks of extensive AMU. British Veterinary Association.

Using an alternative parameterization of the roughness curve we make direct use of critical band results to investigate the role of higher harmonics on the perception of tonal consonance. We scale the spectral amplitudes in the complex home tone and complex interval tone to simulate acoustic signals of constant energy. Our analysis reveals that even with a relatively small addition of higher harmonics the perfect fifth emerges as a consonant interval with more, musically important, just intervals emerging as consonant as more and more energy is shifted into higher frequencies.

The relative importance of wife abuse as a risk factor for violence against children.

Tajima, E A

2000-11-01

To investigate the relative importance of wife abuse as a risk factor for physical child abuse, physical punishment, and verbal child abuse. The study explored the importance of wife abuse relative to blocks of parent, child, and family characteristics and also relative to specific risk factors. This study re-analyzed a sub-sample (N = 2,733) of data from the 1985 National Family Violence Survey. Hierarchical logistic regressions were conducted, using five different criterion variables measuring physical child abuse, physical punishment, and verbal abuse separately and in combination. Blocks of parent, child, and family characteristics were more important predictors of violence towards children than was wife abuse, though the presence of wife abuse in the home was a consistently significant specific risk factor for all forms of violence against children. Of specific risk factors, a respondent's history of having been hit as an adolescent was a larger risk factor for physical child abuse than was wife abuse. Wife abuse was an important predictor of physical punishment. Non-violent marital discord was a greater factor in predicting likelihood of verbal child abuse than was wife abuse. Though this study confirms the association between wife abuse and violence towards children, it cautions us not to overlook the contribution of other factors in our attempts to understand the increased risk attributed to wife abuse.

Leveraging People-Related Maturity Issues for Achieving Higher Maturity and Capability Levels

Science.gov (United States)

Buglione, Luigi

During the past 20 years Maturity Models (MM) become a buzzword in the ICT world. Since the initial Crosby's idea in 1979, plenty of models have been created in the Software & Systems Engineering domains, addressing various perspectives. By analyzing the content of the Process Reference Models (PRM) in many of them, it can be noticed that people-related issues have little weight in the appraisals of the capabilities of organizations while in practice they are considered as significant contributors in traditional process and organizational performance appraisals, as stressed instead in well-known Performance Management models such as MBQA, EFQM and BSC. This paper proposes some ways for leveraging people-related maturity issues merging HR practices from several types of maturity models into the organizational Business Process Model (BPM) in order to achieve higher organizational maturity and capability levels.

Highlights: • High intracellular calcium inhibits Impα/β1- or Impβ1-dependent nuclear protein import. • The effect of Ca 2+ on nuclear import does not relate to changes in the nuclear pore. • High intracellular calcium can result in mislocalisation of Impβ1, Ran and RCC1. - Abstract: We previously showed that increased intracellular calcium can modulate Importin (Imp)β1-dependent nuclear import of SRY-related chromatin remodeling proteins. Here we extend this work to show for the first time that high intracellular calcium inhibits Impα/β1- or Impβ1-dependent nuclear protein import generally. The basis of this relates to the mislocalisation of the transport factors Impβ1 and Ran, which show significantly higher nuclear localization in contrast to various other factors, and RCC1, which shows altered subnuclear localisation. The results here establish for the first time that intracellular calcium modulates conventional nuclear import through direct effects on the nuclear transport machinery

The basic idea behind the use of 'Learning Styles' is that learners can be categorized into one or more 'styles' (e.g., Visual, Auditory, Converger) and that teaching students according to their style will result in improved learning. This idea has been repeatedly tested and there is currently no evidence to support it. Despite this, belief in the use of Learning Styles appears to be widespread amongst schoolteachers and persists in the research literature. This mismatch between evidence and practice has provoked controversy, and some have labeled Learning Styles a 'myth.' In this study, we used a survey of academics in UK Higher Education ( n = 114) to try and go beyond the controversy by quantifying belief and, crucially, actual use of Learning Styles. We also attempted to understand how academics view the potential harms associated with the use of Learning Styles. We found that general belief in the use of Learning Styles was high (58%), but lower than in similar previous studies, continuing an overall downward trend in recent years. Critically the percentage of respondents who reported actually using Learning Styles (33%) was much lower than those who reported believing in their use. Far more reported using a number of techniques that are demonstrably evidence-based. Academics agreed with all the posited weaknesses and harms of Learning Styles theory, agreeing most strongly that the basic theory of Learning Styles is conceptually flawed. However, a substantial number of participants (32%) stated that they would continue to use Learning Styles despite being presented with the lack of an evidence base to support them, suggesting that 'debunking' Learning Styles may not be effective. We argue that the interests of all may be better served by promoting evidence-based approaches to Higher Education.

Whereas TA is a specific case of social phobia, emotional intelligence (EI is an umbrella term covering interpersonal and intrapersonal skills, along with positive stress management, adaptability, and mood. In the present study, we tested the hypothesis that higher EI and lower TA are associated. Further, sex differences were explored.Method: During an exam week, a total of 200 university students completed questionnaires covering sociodemographic information, TA, and EI.Results: Higher scores on EI traits were associated with lower TA scores. Relative to male participants, female participants reported higher TA scores, but not EI scores. Intrapersonal and interpersonal skills and mood predicted low TA, while sex, stress management, and adaptability were excluded from the equation.Conclusion: The pattern of results suggests that efforts to improve intrapersonal and interpersonal skills, and mood might benefit students with high TA. Specifically, social commitment might counteract TA. Keywords: test anxiety, emotional intelligence, students, interpersonal skills, intrapersonal skills

Full Text Available Health-related quality of life (HRQL for nursing home residents is important, however, the concept of quality of life is broad, encompasses many domains and is difficult to assess in people with dementia. Basic activities of daily living (ADL are measured routinely in nursing homes using the Resident Assessment Instrument-Minimum Data Set Version 2.0 (RAI-MDS and Functional Independence Measure (FIM instrument. We examined the relationship between HRQL and ADL to assess the future possibility of ADL dependency level serving as a surrogate measure of HRQL in residents with dementia. To assess ADL, measures derived from the RAI-MDS and FIM data were gathered for 111 residents at the beginning of our study and at 6-month follow-up. Higher scores for independence in ADL were correlated with higher scores for a disease-specific HRQL measure, the Quality of Life—Alzheimer’s Disease Scale. Preliminary evidence suggests that FIM-assessed ADL is associated with HRQL for these residents. The associations of the dressing and toileting items with HRQL were particularly strong. This finding suggests the importance of ADL function in HRQL. The RAI-MDS ADL scales should be used with caution to evaluate HRQL.

Monodromy relations in higher-loop string amplitudes

Directory of Open Access Journals (Sweden)

S. Hohenegger

2017-12-01

Full Text Available New monodromy relations of loop amplitudes are derived in open string theory. We particularly study N-point (planar and non-planar one-loop amplitudes described by a world-sheet cylinder and derive a set of relations between subamplitudes of different color orderings. Various consistency checks are performed by matching α′-expansions of planar and non-planar amplitudes involving elliptic iterated integrals with the resulting periods giving rise to two sets of multiple elliptic zeta values. The latter refer to the two homology cycles on the once-punctured complex elliptic curve and the monodromy equations provide relations between these two sets of multiple elliptic zeta values. Furthermore, our monodromy relations involve new objects for which we present a tentative interpretation in terms of open string scattering amplitudes in the presence of a non-trivial gauge field flux. Finally, we provide an outlook on how to generalize the new monodromy relations to the non-oriented case and beyond the one-loop level. Comparing a subset of our results with recent findings in the literature we find therein several serious issues related to the structure and significance of monodromy phases and the relevance of missed contributions from contour integrations.

2017-01-01

The potential health effects of toxic chemicals (e.g. heavy metals) emitted by municipal solid waste incinerators (MSWIs) are of great concern to local residents, however there have been few studies on the contributions of different exposure pathways and their subsequent effects on the body burden of residents living near MSWIs. In this study, multiple exposure routes of heavy metals including Pb, Cr, Cd and Mn were assessed by investigating the metals in foods (such as vegetables, crops, meats and fruits etc.), drinking water, ambient air and soil collected surrounding an MSWI in Shenzhen, south China. Vegetable ingestion played the most important role in the total average daily dose of Pb and Cr, and cereals were the key exposure routes for Mn and Cd. Compound-specific contaminations were observed in the investigated areas, with Pb and Cr present in the surrounding environment, having accumulated to relatively high levels in the local vegetables, and the intake of contaminated vegetable foods greatly influencing the body burden of Pb and Cr. Consistently, significantly high blood concentrations of Pb and Cr were detected in the local residents compared to a referenced population, and a lack of significant differences was found for Cd and Mn. The results possibly suggested that emission of MSWI influenced the external exposure doses of the major pathways of Pb and Cr in this study, and resulted in the different body burden of metals in humans living near a MSWI. MSWI-local food-humans is an important exposure pathway for residents living near MSWI, and thus should not be neglected in developing future strategies and policies to prevent the high risks suffered by residents living near MSWIs. - Highlights: • Vegetable and cereal ingestion were the main contributors to exposure of Pb/Cr and Mn/Cd, respectively. • Concentrations of Pb/Cr in vegetables grown near MSWI were significantly higher. • Blood concentrations of Pb/Cr in populations near MSWI were

We conducted neuropsychological tests of patients with higher brain dysfunction to examine the characteristics of barriers to employment. We tested 92 patients with higher brain dysfunction (average age of 36.3 +/- 13.8 years old, ranging between 16 and 63 years old, with an average post-injury period of 35.6 +/- 67.8 months) who were hospitalized at the university hospital between February 2002 and June 2007 for further neuropsychological evaluation, conducting the Wechsler Adult Intelligence Scale-Revised (WAIS-R), Wechsler Memory Scale-Revised (WMS-R), the Rivermead Behavioral Memory Test (RBMT), Frontal Assessment Battery (FAB) and Behavioral Assessment of Dysexecutive Syndrome (BADS). The outcomes after discharge were classified between competitive employment, sheltered employment and non-employment, and the three groups were compared using one-way analysis of variance and the Scheffe test. The WAIS-R subtests were mutually compared based on the standard values of significant differences described in the WAIS-R manual. Verbal performance and full scale Intelligence Quotient (IQ) of WAIS-R were 87.7 +/- 15.6 (mean +/- standard deviation), 78.5 +/- 18.1 and 81.0 +/- 17.2, respectively, and verbal memory, visual memory, general memory, attention/concentration and delayed recall were 74.6 +/- 20.0, 76.6 +/- 21.4, 72.0 +/- 20.4, 89.0 +/- 16.5 and 65.2 +/- 20.8, respectively. The competitive employment group showed significantly higher scores in performance IQ and full IQ on the WAIS-R and verbal memory, visual memory, general memory and delayed recall on the WMS-R and RBMT than the non-employment group. The sheltered employment group showed a significantly higher score in delayed recall than the non-employment group. No difference was observed in the FAB or BADS between the three groups. In the subtests of the WAIS-R, the score for Digit Symbol-Coding was significantly lower than almost all the other subtests. For patients with higher brain dysfunction, IQ (full

To measure the plantar pressure in four soccer-related movements in 15 male soccer players (mean (SD) age 20.9 (1.3) years, height 173 (4) cm, weight 61.7 (3.6) kg). To record plantar pressure distribution, the players wore soccer boots with 12 circular studs and with an insole pressure recorder device equipped with 99 sensors. Plantar pressure was recorded in five successful trials in each of the four soccer-related movements: running, sideward cutting, 45 degrees cutting and landing from a vertical jump. Each footprint was divided into 10 recorded areas for analysis. Compared with running at 3.3 m/s, maximal speed sideward cutting and 45 degrees cutting induced higher peak pressure (pplantar surface as compared with the lateral side. These data suggest that the medial side of the plantar surface may be more prone to injuries, and that foot orthosis adoption, improved soccer boot design and specific muscle training could be considered to reduce pressure and the subsequent risk of injury.

Commercialization of higher education: characteristics and trends

Much attention is given to the variety of approaches to the study of higher education. Today, sociological discourses used to analyze modern innovation in the education sphere, such as multiculturalism, diversification, confessionalization, regionalization, cosmopolitan atmosphere in the modern world, including the global information technology to the higher education. In the course of innovation and modernization of higher education, commercialization becomes significantly prevalent a phenomenon and a social process of educational institutions, which requires considerable research. The review of the US and European models of higher education makes it possible to understand the essence of appearance in the literature of such concepts as «academic capitalism», «university of market­type» and «entrepreneurial University», analyze relation to the appearance of private education and income and define the priority of commercialization. Indisputably, with both positive and negative, as a result of the reform of higher education appeared the peculiar environment of business education, which requires the existence of new rules of interaction, status­role relationships, values and norms . In some extent, commercialization is a transformation of knowledge into a commodity (speaking in the context of consumer society; however, it is the growing influence of market relations on the purpose and objectives of higher education, the growth of the importance of knowledge as a resource for economic development that focuses on  the concept of an economy based on knowledge.

The importance of being "me": The relation between authentic identity expression and transgender employees' work-related attitudes and experiences.

2017-02-01

The present research examined the relation between authentic identity expression and transgender employees' work-related attitudes and experiences. Drawing on Kernis' (2003) theoretical conceptualization of authenticity and expanding on current workplace identity management research, we predicted that employees who had taken steps to reduce the discrepancy between their inner gender identities and their outward manifestations of gender would report more positive job attitudes and workplace experiences, in part because the reduction of this discrepancy is related to greater feelings of authenticity. In Study 1, we found that the extent to which one has transitioned was related to higher job satisfaction and perceived person-organization (P-O) fit and lower perceived discrimination. In Study 2, we replicate and extend these results by showing that the extent to which employees felt that others at work perceived them in a manner consistent with how they perceived themselves (relational authenticity) mediated the relations between extent of transition and all 3 of these outcomes. However, perceptions of alignment between one's felt and expressed identity (action authenticity) only mediated this link for job satisfaction. We discuss the theoretical and practical implications of our results, as well as avenues for future research on authenticity in the workplace.

Eklund, Mona; Ostman, Margareta

2010-07-01

It is increasingly acknowledged that satisfaction with sexual relations forms an important aspect of people's lives, but little is known of factors associated with this phenomenon among people with mental illness. This study aimed to investigate how demographic, social, clinical, and health-related factors were related to satisfaction with sexual relations. Patients with persistent mental illness (N = 103), recruited from an outpatient unit, were assessed regarding the target variables. No clinical variable, and only one demographic factor, namely being a cohabitant, was found to be important to satisfaction with sexual relations. Several social factors, pertaining to how everyday occupations were valued and how the social network was perceived, were shown to be of importance. General quality of life, but not self-rated health or interviewer-assessed psychopathology, was also important for satisfaction with sexual relations. A multivariate analysis showed that the most significant factor for satisfaction with sexual relations was how everyday activities were valued, and being a cohabitant explained some additional variation. Previous research indicates that the mental health care services largely neglect sexual problems among people with mental illness, and the findings may provide additional knowledge that may be used in the support of this target group.

Full Text Available Obesity-related eating behaviors (OREB are associated with higher energy intake. Total energy intake can be decomposed into the following constituents: food portion size, food energy density, the number of eating occasions, and the energy intake from energy-rich beverages. To our knowledge this is the first study to examine the association between the OREB and these energy components.Data were taken from a cross-sectional study conducted in 2008-2010 among 11,546 individuals representative of the Spanish population aged ≥ 18 years. Information was obtained on the following 8 self-reported OREB: not planning how much to eat before sitting down, eating precooked/canned food or snacks bought at vending machines or at fast-food restaurants, not choosing low-energy foods, not removing visible fat from meat or skin from chicken, and eating while watching TV. Usual diet was assessed with a validated diet history. Analyses were performed with linear regression with adjustment for main confounders.Compared to individuals with ≤ 1 OREB, those with ≥ 5 OREB had a higher food energy density (β 0.10; 95% CI 0.08, 0.12 kcal/g/day; p-trend<0.001 and a higher consumption of sugary drinks (β 7; 95% CI -7, 20 ml/day; p-trend<0.05 and of alcoholic beverages (β 24; 95% CI 10, 38 ml/day; p-trend<0.001. Specifically, a higher number of OREB was associated with higher intake of dairy products and red meat, and with lower consumption of fresh fruit, oily fish and white meat. No association was found between the number of OREB and food portion size or the number of eating occasions.OREB were associated with higher food energy density and higher consumption of sugary and alcoholic beverages. Avoiding OREB may prove difficult because they are firmly socially rooted, but these results may nevertheless serve to palliate the undesirable effects of OREB by reducing the associated energy intake.

Visualization and processing of higher order descriptors for multi-valued data

CERN Document Server

Schultz, Thomas

2015-01-01

Modern imaging techniques and computational simulations yield complex multi-valued data that require higher-order mathematical descriptors. This book addresses topics of importance when dealing with such data, including frameworks for image processing, visualization, and statistical analysis of higher-order descriptors. It also provides examples of the successful use of higher-order descriptors in specific applications and a glimpse of the next generation of diffusion MRI. To do so, it combines contributions on new developments, current challenges in this area, and state-of-the-art surveys.   Compared to the increasing importance of higher-order descriptors in a range of applications, tools for analysis and processing are still relatively hard to come by. Even though application areas such as medical imaging, fluid dynamics, and structural mechanics are very different in nature they face many shared challenges. This book provides an interdisciplinary perspective on this topic with contributions from key rese...

OREB were associated with higher food energy density and higher consumption of sugary and alcoholic beverages. Avoiding OREB may prove difficult because they are firmly socially rooted, but these results may nevertheless serve to palliate the undesirable effects of OREB by reducing the associated energy intake.

Full Text Available Every academic institution contributes to knowledge. The generated information and knowledge is to be compiled at central place and disseminated among the society for further growth. It is observed that the generated knowledge in the academic institute is not stored or captured properly It is also observed that many a times generated information or knowledge in the academic institute is not known to any one and remains as grey literature, which might be useful if proper recoding is maintained in the organization. In fact academic environment is treasure of knowledge but it is not organized properly and hence utility is also lacking and cause for the repetitions of the activity. This project is undertaken under Board of University and Colleges, University of Pune for finding importance of KM of past knowledge of an institute.

Full Text Available Trust is the basis of social relations and the building block of every society. However, various societies have different levels of social trust, which is a consequence of various cultural dimensions’ as well as historic and economic variables’ interplay. The paper intends to explore the relation of social embeddedness and the level of interpersonal trust in two significantly different cultures – Russian and Hungarian. The results presented in the article are, on the one hand, the outcomes of secondary analysis of the data obtained from the World Values Survey and the European Social Survey, on the other hand, they also offer an insight into the still ongoing primary research on 585 students in business higher education in Hungary and Russia. The results indicate that although there are gender and other demographic variables based differences, social embeddedness and national culture (values, attitudes, behaviour is of relevant influence on the level of interpersonal trust. According to the data presented, the Hungarians – despite being a low-trust nation – in general trust their peers more than the Russians do. However, if we distinguish between two forms of trust – thick and thin – the Hungarians then achieve significantly higher scores in thin trust only.

Objective To measure the plantar pressure in four soccer‐related movements in 15 male soccer players (mean (SD) age 20.9 (1.3) years, height 173 (4) cm, weight 61.7 (3.6) kg). Design To record plantar pressure distribution, the players wore soccer boots with 12 circular studs and with an insole pressure recorder device equipped with 99 sensors. Plantar pressure was recorded in five successful trials in each of the four soccer‐related movements: running, sideward cutting, 45° cutting and landing from a vertical jump. Each footprint was divided into 10 recorded areas for analysis. Results Compared with running at 3.3 m/s, maximal speed sideward cutting and 45° cutting induced higher peak pressure (pplantar surface as compared with the lateral side. Conclusions These data suggest that the medial side of the plantar surface may be more prone to injuries, and that foot orthosis adoption, improved soccer boot design and specific muscle training could be considered to reduce pressure and the subsequent risk of injury.

2015-12-01

Full Text Available The article explores quality-related funding and its global outcomes in the context of Romanian higher education by focusing on the funding allocations provided to public universities throughout a period of nine years based on their institutional performance on the quality indicators integrated in the funding algorithm. Global funding allocations between universities are analysed and a summative appraisal for the entire nine-year window is provided. The article also explores the relation between quality- related funding, institutional disciplinary profiles and the results of a comprehensive evaluation conducted in 2011 by the Ministry of Education to complete a classification of the universities. The main findings indicate a low overall impact of qualityrelated funding for many institutions, but also a clear pattern in which universities focused on science, technology, engineering and mathematics overwhelmingly outperformed mixed institutions, as well as those focused on humanities, arts and social sciences. Furthermore, the global quality-related funding outcomes of the 2003 – 2011 period studied in the paper are shown to be significantly associated with the results of the 2011 classification

This study's purpose was twofold: first, to examine the relative importance of job demands and resources as predictors of burnout and engagement, and second, the relative importance of engagement and burnout related to health, depressive symptoms, work ability, organizational commitment, and turnover intentions in two samples of health care workers. Nurse leaders (n = 162) and licensed emergency medical technicians (EMTs; n = 102) completed surveys. In both samples, job demands predicted burnout more strongly than job resources, and job resources predicted engagement more strongly than job demands. Engagement held more weight than burnout for predicting commitment, and burnout held more weight for predicting health outcomes, depressive symptoms, and work ability. Results have implications for the design, evaluation, and effectiveness of workplace interventions to reduce burnout and improve engagement among health care workers. Actionable recommendations for increasing engagement and decreasing burnout in health care organizations are provided. © 2016 The Author(s).

Other than the needs for infection control to investigate the survival and inactivation of airborne bacterial pathogens, there has been a growing interest in exploring bacterial communities in the air and the effect of environmental variables on them. However, the innate biological mechanism influencing the bacterial viability is still unclear. In this study, a mutant-based approach, using Escherichia coli as a model, was used to prove the concept that common stress-response genes are important for airborne survival of bacteria. Mutants with a single gene knockout that are known to respond to general stress (rpoS) and oxidative stress (oxyR, soxR) were selected in the study. Low relative humidity (RH), 30-40% was more detrimental to the bacteria than high RH, >90%. The log reduction of ∆rpoS was always higher than that of the parental strain at all RH levels but the ∆oxyR had a higher log reduction than the parental strain at intermediate RH only. ∆soxR had the same viability compared to the parental strain at all RH levels. The results hint that although different types and levels of stress are produced under different RH conditions, stress-response genes always play a role in the bacterial viability. This study is the first reporting the association between stress-response genes and viability of airborne bacteria.

Full Text Available In the study we examined the relationship between the importance and realization of values and subjective emotional well being of Slovenian and British subjects. The overall results were in concordance with telic and hedonistic theory of subjective emotional well being within both samples. Also the correlations between subjective emotional well being and fulfilled value orientation were in both samples substantially higher than the correlation between subjective emotional well being and value orientation itself. The finding of profound similarities in the relation between subjective emotional well being and the realization of general value orientation in Slovenian and British sample is interesting and deserves special attention and further research. The fulfillment of hedonic or dionisic values, respectively, was found to be the strongest predictor of subjective emotional well being of Slovenian and British subjects.

Full Text Available Since 2010, the Brazilian communitarian institutions for higher education are not included officially under this designation in the INEP’s microdata, with the extinction of the category “communitarian, religious and philanthropic”. Since then, the Brazilian private’s higher education institutions are classified according to their legal nature: for-profit or non-profit. Nevertheless, the new law 12.881 of 2013, enacted in November 2013, has changed this reality after the approval by the National Congress, establishing the definition and purpose of the Community institutions, and confirming, in particular, their characteristics of non-profit institutions belonging to civil society, and their organization into associations or foundations (BRAZIL, 2013. The recent expansion of the federal and for-profit higher education institutions has directly affected the so far called communitarian institutions, which present differentiated characteristics compared to forprofit private higher education institutions as well as public education. In this article, data and contemporary aspects related to the new scenario of Brazilian higher education are analyzed, with special focus on higher education institutions members of the Association of Community Universities (ABRUC, and were found better performance of these ones in comparison to the private for-profit higher education institutions. The obtained results, combined with the regional impact of the communitarian higher education institutions, justify the importance of these institutions to improve the consolidation of higher education in Brazil.

Full Text Available New businesses arising at the market usually operate in the sector of small and medium-sized enterprises and account for a significant part of the whole global economy. Not only the success of a start-up company, but also its sequel within the SME sector are significantly influenced by entrepreneur's personality. The aim of this article is to explore the attitude to financial risk in relation to sociodemographic characteristics (gender, education, age and the most important personality traits of entrepreneurs (risk-taking, decisiveness, optimism. We have analyzed the data collected from 1141 respondents during 2015 in 14 regions of Czech Republic. Empirical results of our paper show that the researched entrepreneurs rather can't manage financial risks in their firms regardless their gender, education, age or personality traits. Most entrepreneurs consider the importance of financial risk to increase during the crisis period. These opinions differed in relation to age, gender and such personality traits as "decisiveness" and "optimism". The results also show that the entrepreneurs try to minimise the financial risk through building-up reserves in relation to such qualities as "risk-taking" and "decisiveness" in comparison to a rather negative attitude to "optimism".

Body lift, drag and power are relatively higher in large-eared than in small-eared bat species.

Håkansson, Jonas; Jakobsen, Lasse; Hedenström, Anders; Johansson, L Christoffer

2017-10-01

Bats navigate the dark using echolocation. Echolocation is enhanced by external ears, but external ears increase the projected frontal area and reduce the streamlining of the animal. External ears are thus expected to compromise flight efficiency, but research suggests that very large ears may mitigate the cost by producing aerodynamic lift. Here we compare quantitative aerodynamic measures of flight efficiency of two bat species, one large-eared ( Plecotus auritus ) and one small-eared ( Glossophaga soricina ), flying freely in a wind tunnel. We find that the body drag of both species is higher than previously assumed and that the large-eared species has a higher body drag coefficient, but also produces relatively more ear/body lift than the small-eared species, in line with prior studies on model bats. The measured aerodynamic power of P. auritus was higher than predicted from the aerodynamic model, while the small-eared species aligned with predictions. The relatively higher power of the large-eared species results in lower optimal flight speeds and our findings support the notion of a trade-off between the acoustic benefits of large external ears and aerodynamic performance. The result of this trade-off would be the eco-morphological correlation in bat flight, with large-eared bats generally adopting slow-flight feeding strategies. © 2017 The Author(s).

Higher B-cell activating factor levels at birth are positively associated with maternal dairy farm exposure and negatively related to allergy development.

A high proportion of circulating immature/naive CD5(+) B cells during early infancy is a risk factor for allergy development. B-cell activating factor (BAFF) is an important cytokine for B-cell maturation. We sought to investigate whether BAFF levels are related to environmental exposures during pregnancy and early childhood and whether BAFF levels are associated with postnatal B-cell maturation and allergic disease. In the FARMFLORA study, including both farming and nonfarming families, we measured BAFF levels in plasma from mothers and their children at birth and at 1, 4, 18, and 36 months of age. Infants' blood samples were also analyzed for B-cell numbers and proportions of CD5(+) and CD27(+) B cells. Allergic disease was clinically evaluated at 18 and 36 months of age. Circulating BAFF levels were maximal at birth, and farmers' children had higher BAFF levels than nonfarmers' children. Higher BAFF levels at birth were positively associated with proportions of CD27(+) memory B cells among farmers' children and inversely related to proportions of CD5(+) immature/naive B cells among nonfarmers' children. Children with allergic disease at 18 months of age had lower cord blood BAFF levels than nonallergic children. At birth, girls had higher BAFF levels and lower proportions of CD5(+) B cells than boys. Farm exposure during pregnancy appears to induce BAFF production in the newborn child, and high neonatal BAFF levels were associated with more accelerated postnatal B-cell maturation, which lend further strength to the role of B cells in the hygiene hypothesis.

Full Text Available Historically, education has always been the springboard for socio-economic development of nations. Undoubtedly, education proved to be the catalyst of change and the front wagon that drives with it all the other wagons pertaining to other dynamic sectors. In effect, the role of education can be seen to provide pupils with the curriculum and hidden curriculum skills alike; teaching skills that will prepare them physically, mentally and socially for the world of work in later life. In Morocco, the country spends over 26% of its Gross Domestic Product (GDP on education. Unfortunately, though this number is important, Moroccan education (primary, secondary and higher education alike still suffers from the mismatch between the state expenditures on education and the general product in reality. In this article, an attempt is made to touch on some relevant issues pertaining to higher education with special reference to Morocco. First, it provides some tentative definitions, mission and functions of university and higher education. Second, it gives a historical sketch of the major reforms that took place in Morocco as well as the major changes pertaining to these reforms respectively. Third, it provides a general overview of the history of higher education in Morocco, it also tackles an issue related to governance in higher education which is cost sharing. Fourth, it delves into the history of English Language Teaching (ELT, lists some characteristics of the English Departments in Morocco. Fifth, it discusses the issue of private vs. public higher education. Last, but not least, it tackles the issue of Brain Drain.

The relative importance of physical and biological energy in landscape evolution

Turowski, J. M.; Schwanghart, W.

2017-12-01

Landscapes are formed by the interplay of uplift and geomorphic processes, including interacting and competing physical and biological processes. For example, roots re-inforce soil and thereby stabilize hillslopes and the canopy cover of the forest may mediate the impact of precipitation. Furthermore, plants and animals act as geomorphic agents, directly altering landscape response and dynamics by their actions: tree roots may crack rocks, thus changing subsurface water flows and exposing fresh material for denudation; fungi excrete acids that accelerate rates of chemical weathering, and burrowing animals displace soil and rocks while digging holes for shelter or in search of food. Energetically, landscapes can be viewed as open systems in which topography stores potential energy above a base level. Tectonic processes add energy to the system by uplift and mechanically altering rock properties. Especially in unvegetated regions, erosion and transport by wind can be an important geomorphic process. Advection of atmospheric moisture in high altitudes provides potential energy that is converted by water fluxes through catchments. At the same time, the conversion of solar energy through atmospheric and biological processes drives primary production of living organisms. If we accept that biota influence geomorphic processes, then what is their energetic contribution to landscape evolution relative to physical processes? Using two case studies, we demonstrate that all components of energy input are negligible apart from biological production, quantified by net primary productivity (NPP) and potential energy conversion by water that is placed high up in the landscape as rainfall and leaves it as runoff. Assuming that the former is representative for biological energy and the latter for physical energy, we propose that the ratio of these two values can be used as a proxy for the relative importance of biological and physical processes in landscape evolution.

Adolescence is transitional stage of physical and mental human development occuring between childhood and adult life. Social interactions and environmental factors together are important predictors of adolescent cannabis use. This study aimed to examine the relationship between the social determinants and adolescents behavior with cannabis consumption. A cross sectional study as part of the European School Survey Project on Alcohol and other Drugs was conducted among 6.150 adolescents aged 16 years in three regions of Serbia, and three types of schools (gymnasium, vocational - professional, and vocational - handicraft) during May - June 2008. A multivariate logistic regression analysis was carried out to obtain adjusted odds ratios with 95% confidence intervals in which the dependent variable was cannabis consumption non-user and user. Among 6.7% of adolescents who had tried cannabis at least one in their lives, boys were more involved in cannabis use than girls, especially boys from gymnasium school. Well off family, lower education of mother, worse relations with parents were significantly associated with cannabis use (P related to cannabis use (P study confirmed the importance of family relationship development.

Full text: he main purpose of this work is to show that massless Dirac equation formulated for non-interacting Majorana-Weyl spinors in higher dimensions, particularly in D = 1 + 9 and D = 5 + 5, may yield to an interpretation of massive Majorana and Dirac spinors in D = 1 + 3 dimensions. The particular case of a dimensional reduction from D = 4 + 4 to D = 1 + 3 has already been fairly-well discussed in the literature. By adopting suitable representations of the Dirac matrices in higher dimensions, we pursue the investigation of which higher dimensional space-times and which metric signatures concerning massless Dirac equations in highermay induce massive spinors in D = 1+3 dimensions. The mixing of the chiral fermions in higher dimensions may induce a mechanism such that four massive Majorana fermions may show up and, at an appropriate limit an almost zero and a huge mass show up with corresponding left-handed and right-handed eigenstates. This mechanism could reassess a peculiar connection with the See-Saw scheme associated to neutrino with Majorana-type masses. The masses of the particle are fixed by the dimensional reduction scheme, which the decoupled dimensions contribute coordinates and depend on the mass invariants in lower dimensions. This proposal should allow us to understand the generation of hierarchies for the fermionic masses in D = 1 + 3, or in lower dimensions in general, starting from the constraints between the energy and the momentum in (n; n) dimensions. For the initial D = 5 + 5 Majorana-Weyl spinors framework using the Weyl representation to the Dirac matrices we observe an intriguing decomposition of space-time that result in two equivalent D = 1 + 4 massive spinors which mass term, in D = 1 + 3 included, is originated from the remained component and that could induce a Brane-World mechanism.

Full Text Available BACKGROUND: There is a proposed link between dietary zinc intake and atherosclerosis, but this relationship remains unclear. Phytate may contribute to this relationship by influencing zinc bioavailability. OBJECTIVE: The aim of this study is to examine the relationship between zinc bioavailability and subclinical atherosclerosis in healthy Korean adults. MATERIALS AND METHODS: The present cross-sectional analysis used baseline data from the Korean multi-Rural Communities Cohort Study (MRCohort, which is a part of The Korean Genome Epidemiology Study (KoGES. A total of 5,532 subjects (2,116 men and 3,416 women aged 40 years and older were recruited from rural communities in South Korea between 2005 and 2010. Phytate:zinc molar ratio, estimated from a food-based food frequency questionnaire (FFQ of 106 food items, was used to determine zinc bioavailability, and carotid intima media thickness (cIMT and pulse wave velocity (PWV were measured to calculate the subclinical atherosclerotic index. RESULTS: We found that phytate:zinc molar ratio is positively related to cIMT in men. A higher phytate:zinc molar ratio was significantly related to an increased risk of atherosclerosis in men, defined as the 80(th percentile value of cIMT (5(th vs. 1(st quintile, OR = 2.11, 95% CI 1.42-3.15, P for trend = 0.0009, and especially in elderly men (5(th vs. 1(st quintile, OR = 2.58, 95% CI 1.52-4.37, P for trend = 0.0021. We found a positive relationship between phytate:zinc molar ratio and atherosclerosis risk among women aged 65 years or younger. Phytate:zinc molar ratio was not found to be related to PWV. CONCLUSIONS: Lower zinc bioavailability may be related to higher atherosclerosis risk.

The relative dietary importance of haem and non-haem iron

1983-01-01

A study was undertaken to find out the relative amounts of haem and non-haem iron absorbed from meals in which varying amounts of these substances were present. Four meals, each containing 6 mg of iron but with varying ratios of haem and non-haem iron, were fed to two groups of subjects, each group receiving two meals. The geometric mean percentage absorption of non-haem iron decreased from 18,0% (SD range 14,6-22,3%) to 6,4% (SD range 3,4-11,8%) as the non-haem iron content of the meal increased from 1,52 mg to 5,72 mg - there was therefore little variation in the actual amounts of non-haem iron absorbed from the different meals. In contrast, the geometric mean absorption of haem iron was approximately 20% from all four meals, although the haem iron content varied between 0,28 mg and 4,48 mg. The amount of haem iron absorbed was thus a linear function of the amount of haem iron in the meal. Two points emerged from the study. Firstly, the relative importance of haem iron in overall iron nutrition was confirmed. Secondly, the fact that the pattern of absorption in relation to dosage was so different from haem iron and non-haem iron suggested that a controlling mechanism for non-haem iron absorption may be located at the mucosal surface. This conclusion is based on the fact that haem iron, the percentage absorption of which was found to be independent of the size of the dose, is absorped into the mucosal cell when still contained within the porphyrin ring and the iron thus bypasses some controlling mechanism at the mucosal border

Relative importance and interrelations between psychosocial factors and individualized quality of life of hemodialysis patients.

Tovbin, David; Gidron, Yori; Jean, Tzipora; Granovsky, Ricardo; Schnieder, Alla

2003-09-01

Since quality of life (QOL) of hemodialysis (HD) patients is low and frequently difficult to improve by medical therapy, it is important to identify psychosocial correlates and life-domains important for HD patients' QOL. Our hypothesis was that psychosocial factors reflecting appraisal, external and internal resources/impediments correlate with QOL and compensate for adverse effects of disease-related variables on QOL. Forty-eight chronic HD-patients identified and rank-ordered life-domains important for QOL and rated their level of satisfaction with those domains. This was performed using a slightly modified version of the Self-Evaluated Individualized QOL (SEiQOL) Scale. Psychosocial factors included perceived-control (PC), social-support and hostility. Demographic and disease-related factors included age, gender, cardiovascular disease (CVD), diabetes, hematocrit, albumin and C-reactive protein. QOL was significantly correlated with PC (r = 0.65) and social-support (r = 0.38), and inversely correlated with hostility (r = -0.31), diabetes and hypoalbuminemia (all at least p < 0.05). PC mediated effects of certain variables (e.g., albumin, gender, hostility) and moderated effects of little social-support and hypoalbuminemia on QOL. Patients' most important QOL domains were health, with which satisfaction was lowest, followed by family, with which satisfaction was highest. Pending replication with larger samples, assessment and enhancement of PC may improve HD patients' QOL.

It is generally believed that maltose drives yeast-mediated bread dough fermentation. The relative importance of fructose and glucose, released from wheat fructan and sucrose by invertase, compared to maltose is, however, not documented. This is surprising given the preference of yeast for glucose and fructose over maltose. This study revealed that, after 2h fermentation of wheat flour dough, about 44% of the sugars consumed were generated by invertase-mediated degradation of fructan, raffinose and sucrose. The other 56% were generated by amylases. In whole meal dough, 70% of the sugars consumed were released by invertase activity. Invertase-mediated sugar release seems to be crucial during the first hour of fermentation, while amylase-mediated sugar release was predominant in the later stages of fermentation, which explains why higher amylolytic activity prolonged the productive fermentation time only. These results illustrate the importance of wheat fructan and sucrose content and their degradation for dough fermentations. Copyright © 2016 Elsevier Ltd. All rights reserved.

Scott, Shannon Rich; Rosen, Lisa H

2015-06-01

The purpose of the current study was to examine the relative impact of actual and perceived weight, weight importance, entity mindset, and ethnicity on anti-fat attitudes as well as to examine whether certain variables play the role of mediator. Participants included a multiethnic U.S. sample of 923 female undergraduates who completed a series of measures online. Lower BMI, higher perceived weight, higher importance of weight, endorsement of an entity mindset, and identification as White as compared to Black, Hispanic, or Asian predicted higher overall anti-fat attitudes. Examination of the individual Antifat Attitudes Questionnaire subscales (i.e. dislike, fear of fat, and willpower) using Relative Weight Analysis suggested that weight importance is an important predictor of multiple aspects of anti-fat attitudes. In addition, weight importance mediated the relationship between perceived weight and fear of fat as well as the relationship between ethnicity and dislike. Implications of findings and future research directions are discussed.

Concerns with taste, nutrition, cost, and convenience are said to be key influences on food choices. This study examined the importance of food-related attitudes in relation to diet quality using US national level data. Interactions by socioeconomic status (SES), gender and race/ethnicity were tested. Analyses of 8957 adults from National Health and Nutrition Examination Survey (NHANES 2007-2010) were conducted in 2014-15. Perceived importance of taste, nutrition, cost, and convenience in dietary choices were assessed using 4-point Likert scales. Education and family income-to-poverty ratio (FIPR) were SES indicators. Healthy Eating Index (HEI-2010), a measure of adherence to 2010 dietary guidelines, was the diet quality measure. Survey-weighted regressions examined associations between attitudes and HEI, and tested for interactions. Taste was rated as "very important" by 77.0% of the US adults, followed by nutrition (59.9%), cost (39.9%), and convenience (29.8%). However, it was the perceived importance of nutrition that most strongly predicted HEI (β: +8.0 HEI scores among "very important" vs. "not at all important"). By contrast, greater importance for taste and convenience had a weak inverse relation with HEI (β: -5.1 and -1.5 respectively), adjusting for SES. Significant interactions were observed by race/ethnicity, but not SES and gender. Those who prioritized nutrition during food shopping had higher-quality diets regardless of gender, education and income in the US. Certain racial/ethnic groups managed to eat healthy despite attaching importance to cost and convenience. This is the first evidence of nutrition resilience among US adults using national data, which has huge implications for nutrition interventions. Published by Elsevier Inc.

Importance of molybdenum in the nitrogen metabolism of microorganisms and higher plants

Energy Technology Data Exchange (ETDEWEB)

Mulder, E G

1948-01-01

The effect of molybdenum on the growth of microorganisms and higher plants and on some well-defined biochemical reactions was investigated. Results indicate that Aspergillus niger requires small amounts of molybdenum when growing in a culture solution supplied with nitrate nitrogen. With ammonium sulfate as a source of nitrogen, the response of the fungus to molybdenum was much smaller. It was shown that this different response of Aspergillus to molybdenum was not brought about by a difference in purity of both nitrogen compounds used, nor by a difference in absorption of the molybdenum impurity, but by a considerably higher requirement of molybdenum in a medium with nitrate nitrogen. The growth-rate curve and the increasing sporulation of Aspergillus niger with increasing amounts of molybdenum were used in estimating very small amounts of this element in various materials. In culture solution experiments with tomato, barley and oat plants the effect of traces of molybdenum on the growth of these plants was investigated. In good agreement with the results of the experiments with Aspergillus and denitrifying bacteria it could be shown that in the green plant as in these microorganisms molybdenum is acting as a catalyst in nitrate reduction. In experiments with Azotobacter chroococcum and leguminous plants the effect of molybdenum on the fixation of gaseous N/sub 2/ was studied. In culture solutions with pea plants the effect of molybdenum on the nitrogen fixation of the nodules was investigated. In the absence of molybdenum as well as in a complete nutrient medium many nodules were formed. 30 references, 6 figures, 16 tables.

Colorectal cancer (CRC) screening rates are suboptimal. The most important barriers identified by patients are poorly understood. A comprehensive assessment of barriers to all recommended modalities is needed. In 2007, a questionnaire was mailed to 6100 patients, aged 50-75 years, from 12 family medicine practices in the Virginia Ambulatory Care Outcomes Research Network. People aged 65-75 years and African Americans were oversampled. Patients were asked to rate 19-21 barriers to each of four recommended tests. In 2008, responses were coded on a 5-point scale; higher scores reflected stronger barrier endorsement. The response rate was 55% (n=3357). Approximately 40% of respondents were aged >/=65 years, 30% were African-American, and 73% were adherent to screening. A clinician's failure to suggest screening and not knowing testing was necessary received the highest mean scores as barriers. Financial concerns and misconceptions were also cited. Barrier scores differed depending on whether respondents were never screened, overdue for screening, or adherent to guidelines. The top five barriers for each modality included test-specific barriers (e.g., handling stool, bowel preparation), which often outranked generic barriers to screening. Not knowing testing was necessary was a top barrier for all tests but colonoscopy. Although physician advice and awareness of the need for screening are important, barriers to screening are not homogenous across tests, and test-specific barriers warrant consideration in designing strategies to improve screening rates. Barrier scores differ by screening status, highlighting the need to address prior screening experience. Evidence that patients are more familiar with colonoscopy than with other modalities suggests an opportunity to improve screening rates by educating patients about alternative tests. 2010 American Journal of Preventive Medicine.

Vanhonacker, F; Verbeke, W

2009-12-01

A substantial number of studies has already investigated differences within the consumer market with regard to attitudes and perceptions in relation to farm animal welfare. Likewise, several studies focused on the gap that exists between positive attitudes and reported consumption or purchase intentions for sustainable food products in general and higher welfare products more specific, and on the factors influencing this attitude-behavior gap. Little or no studies, however, have started from reported pro-welfare behavior to distinguish between consumer groups and to explore the motivations of the respective behavior. With this study, we aim to group consumers according to their reported buying frequency of higher welfare eggs and higher welfare chicken meat. Similarities and dissimilarities between these groups are mapped in terms of individual characteristics, product attribute importance, perceived consumer effectiveness, perception of higher welfare products, and attitude toward a welfare label. The research methodology applied was a quantitative study with cross-sectional consumer survey data collected in Flanders in spring 2007 (n = 469). Pro-welfare behavior was unevenly distributed across different consumer segments, despite a general interest and concern for bird welfare. A consistent choice for standard (no welfare premium) poultry products was related to strong perceived price and availability barriers, to a low importance attached to ethical issues as product attributes, and to a low perceived consumer effectiveness. A consistent choice for products with higher welfare standards to the contrast associated with a high importance attached to ethical issues; a low effect of price and availability perception; a strong association of higher welfare products with product attributes like health, taste, and quality; and a high perceived consumer effectiveness. The identification of market segments with common characteristics is essential for positioning higher

Quantifying relative importance: Computing standardized effects in models with binary outcomes

Science.gov (United States)

Grace, James B.; Johnson, Darren; Lefcheck, Jonathan S.; Byrnes, Jarrett E.K.

2018-01-01

Scientists commonly ask questions about the relative importances of processes, and then turn to statistical models for answers. Standardized coefficients are typically used in such situations, with the goal being to compare effects on a common scale. Traditional approaches to obtaining standardized coefficients were developed with idealized Gaussian variables in mind. When responses are binary, complications arise that impact standardization methods. In this paper, we review, evaluate, and propose new methods for standardizing coefficients from models that contain binary outcomes. We first consider the interpretability of unstandardized coefficients and then examine two main approaches to standardization. One approach, which we refer to as the Latent-Theoretical or LT method, assumes that underlying binary observations there exists a latent, continuous propensity linearly related to the coefficients. A second approach, which we refer to as the Observed-Empirical or OE method, assumes responses are purely discrete and estimates error variance empirically via reference to a classical R2 estimator. We also evaluate the standard formula for calculating standardized coefficients based on standard deviations. Criticisms of this practice have been persistent, leading us to propose an alternative formula that is based on user-defined “relevant ranges”. Finally, we implement all of the above in an open-source package for the statistical software R.

Conditional health-related benefits of higher education: an assessment of compensatory versus accumulative mechanisms.

Science.gov (United States)

Bauldry, Shawn

2014-06-01

A college degree is associated with a range of health-related benefits, but the effects of higher education are known to vary across different population subgroups. Competing theories have been proposed for whether people from more or less advantaged backgrounds or circumstances will gain greater health-related benefits from a college degree. This study draws on data from the National Longitudinal Study of Adolescent Health (Add Health) and recently developed models for analyzing heterogeneous treatment effects to examine how the effect of obtaining a college degree on the self-rated health of young adults varies across the likelihood of obtaining a college degree, a summary measure of advantage/disadvantage. Results indicate that a college degree has a greater effect on self-rated health for people from advantaged backgrounds. This finding differs from two recent studies, and possible reasons for the contrasting findings are discussed. Copyright © 2014 Elsevier Ltd. All rights reserved.

The relative importance of water temperature and residence time in predicting cyanobacteria abundance in regulated rivers.

Cha, YoonKyung; Cho, Kyung Hwa; Lee, Hyuk; Kang, Taegu; Kim, Joon Ha

2017-11-01

Despite a growing awareness of the problems associated with cyanobacterial blooms in rivers, and particularly in regulated rivers, the drivers of bloom formation and abundance in rivers are not well understood. We developed a Bayesian hierarchical model to assess the relative importance of predictors of summer cyanobacteria abundance, and to test whether the relative importance of each predictor varies by site, using monitoring data from 16 sites in the four major rivers of South Korea. The results suggested that temperature and residence time, but not nutrient levels, are important predictors of summer cyanobacteria abundance in rivers. Although the two predictors were of similar significance across the sites, the residence time was marginally better in accounting for the variation in cyanobacteria abundance. The model with spatial hierarchy demonstrated that temperature played a consistently significant role at all sites, and showed no effect from site-specific factors. In contrast, the importance of residence time varied significantly from site to site. This variation was shown to depend on the trophic state, indicated by the chlorophyll-a and total phosphorus levels. Our results also suggested that the magnitude of weir inflow is a key factor determining the cyanobacteria abundance under baseline conditions. Copyright © 2017 Elsevier Ltd. All rights reserved.

Full Text Available Abstract A 56-year-old man noticed discomfort in his left lower limb, followed by convulsion and numbness in the same area. Magnetic resonance imaging (MRI showed white matter lesions in the right parietal lobe accompanied by leptomeningeal or leptomeningeal and cortical post-contrast enhancement along the parietal sulci. The patient also exhibited higher brain dysfunction corresponding with the lesions on MRI. Histological pathology disclosed β-amyloid in the blood vessels and perivascular inflammation, which highlights the diagnosis of cerebral amyloid angiopathy (CAA-related inflammation. Pulse steroid therapy was so effective that clinical and radiological findings immediately improved. CAA-related inflammation is a rare disease, defined by the deposition of amyloid proteins within the leptomeningeal and cortical arteries associated with vasculitis or perivasculitis. Here we report a patient with CAA-related inflammation who showed higher brain dysfunction that improved with steroid therapy. In cases with atypical radiological lesions like our case, cerebral biopsy with histological confirmation remains necessary for an accurate diagnosis.

Evidence-Based Higher Education – Is the Learning Styles ‘Myth’ Important?

Science.gov (United States)

Newton, Philip M.; Miah, Mahallad

2017-01-01

The basic idea behind the use of ‘Learning Styles’ is that learners can be categorized into one or more ‘styles’ (e.g., Visual, Auditory, Converger) and that teaching students according to their style will result in improved learning. This idea has been repeatedly tested and there is currently no evidence to support it. Despite this, belief in the use of Learning Styles appears to be widespread amongst schoolteachers and persists in the research literature. This mismatch between evidence and practice has provoked controversy, and some have labeled Learning Styles a ‘myth.’ In this study, we used a survey of academics in UK Higher Education (n = 114) to try and go beyond the controversy by quantifying belief and, crucially, actual use of Learning Styles. We also attempted to understand how academics view the potential harms associated with the use of Learning Styles. We found that general belief in the use of Learning Styles was high (58%), but lower than in similar previous studies, continuing an overall downward trend in recent years. Critically the percentage of respondents who reported actually using Learning Styles (33%) was much lower than those who reported believing in their use. Far more reported using a number of techniques that are demonstrably evidence-based. Academics agreed with all the posited weaknesses and harms of Learning Styles theory, agreeing most strongly that the basic theory of Learning Styles is conceptually flawed. However, a substantial number of participants (32%) stated that they would continue to use Learning Styles despite being presented with the lack of an evidence base to support them, suggesting that ‘debunking’ Learning Styles may not be effective. We argue that the interests of all may be better served by promoting evidence-based approaches to Higher Education. PMID:28396647

Why are agricultural impacts of climate change so uncertain? The importance of temperature relative to precipitation

International Nuclear Information System (INIS)

Lobell, David B; Burke, Marshall B

2008-01-01

Estimates of climate change impacts are often characterized by large uncertainties that reflect ignorance of many physical, biological, and socio-economic processes, and which hamper efforts to anticipate and adapt to climate change. A key to reducing these uncertainties is improved understanding of the relative contributions of individual factors. We evaluated uncertainties for projections of climate change impacts on crop production for 94 crop-region combinations that account for the bulk of calories consumed by malnourished populations. Specifically, we focused on the relative contributions of four factors: climate model projections of future temperature and precipitation, and the sensitivities of crops to temperature and precipitation changes. Surprisingly, uncertainties related to temperature represented a greater contribution to climate change impact uncertainty than those related to precipitation for most crops and regions, and in particular the sensitivity of crop yields to temperature was a critical source of uncertainty. These findings occurred despite rainfall's important contribution to year-to-year variability in crop yields and large disagreements among global climate models over the direction of future regional rainfall changes, and reflect the large magnitude of future warming relative to historical variability. We conclude that progress in understanding crop responses to temperature and the magnitude of regional temperature changes are two of the most important needs for climate change impact assessments and adaptation efforts for agriculture

To compare the metabolic, anthropometric, arterial blood pressure, and muscle strength parameters of elderly women with and without metabolic syndrome. A case-control study with 27 (67.3±4.8 years of age, 31.0±5.0kg/m{sup 2}) elderly women with metabolic syndrome and 33 (68.8±5.6 years of age, 27.2±5.3kg/m{sup 2}) sedentary control elderly women. They were submitted to an evaluation of body composition by means of dual-energy X-ray absorptiometry and muscle strength testing with 10 maximal repetitions of knee extension. When compared to the elderly women without metabolic syndrome, those with the metabolic syndrome had higher levels for body mass (72.2±13.5 versus 63.4±14.6kg, p=0.03), body mass index (31.0±5.0 versus 27.2±5.3kg/m{sup 2,} p=0.007), fat mass (30.9±9.9 versus 24.4±8.5kg, p=0.01), systolic arterial pressure (125.1±8.2 versus 119.3±8.7mmHg, p=0.01), diastolic arterial pressure (75.5±6.9 versus 71.4±6.7mmHg, p=0.03), mean arterial pressure (92.5±6.2 versus 87.1±6.7mmHg, p=0.004), blood glucose (103.8±19.1 versus 91.1±5.9mg/dL, p=0.001), triglycerides (187.1±70.2 versus 116.3±36.7mg/dL, p=0.001), and creatine kinase (122.6±58.6 versus 89.8±32.5U/L, p=0.01); lower levels were found for fat-free mass (55.9±5.8 versus 59.3±6.7%; p=0.05), HDL-C (40.7±5.0 versus 50.5±10.1mg/dL, p=0.001), and relative muscle strength (0.53±0.14 versus 0.62±0.12, p=0.01). Elderly women with metabolic syndrome have a higher cardiovascular risk and less relative muscle strength when compared to those without metabolic syndrome. Relative muscle strength may be related to the cardiovascularr risk factors of the metabolic syndrome.

2010-01-01

This paper provides an insight into energy efficiency interventions studies, focusing on issues arising in UK higher education institutions (HEIs) in particular. Based on a review of the context for energy efficiency and carbon reduction programmes in the UK and the trends in higher education sector, existing external and internal policies and initiatives and their relevant issues are extensively discussed. To explore the efficacy of some internal intervention strategies, such as technical, non-technical and management interventions, a survey was conducted among UK higher education institutions between February and April 2008. Consultation responses show that there are a relatively high percentage of institutions (83%) that have embarked on both technical and non-technical initiatives, which is a demonstration to the joined-up approach in such area. Major barriers for intervention studies are also identified, including lack of methodology, non-clarity of energy demand and consumption issues, difficulty in establishing assessment boundaries, problems with regards to indices and their effectiveness and so on. Besides establishing clear targets for carbon reductions within the sector, it is concluded that it is important to develop systems for effectively measuring and evaluating the impact of different policies, regulations and schemes in the future as the first step to explore. - Research Highlights: → The research provides an insight into energy efficiency interventions studies, focusing particularly on issues arising in UK higher education institutions (HEIs). → Based on a review of the context for energy efficiency and carbon reduction programmes in the UK and the trends in higher education sector, existing external and internal policies and initiatives, and their relevant issues are extensively discussed. → To explore the efficacy of some internal intervention strategies, such as technical, non-technical and management interventions, a survey was conducted

The member states are responsible for organizing and operating their education and training systems themselves. And, EU policy is aimed at supporting the efforts of member states and trying to find solutions for the common challenges which appear. In order to make our future sustainable maximally; the key to it lies in education. The highly qualified workforce is the key to development, advancement and innovation of the world. Nowadays, the competitiveness of higher education institutions has become more and more appreciated in the national economy. In recent years, the frameworks of operation of higher education systems have gone through a total transformation. The number of applying students is continuously decreasing in some European countries therefore only those institutions can “survive” this shortfall, which are able to minimize the loss of the number of students. In this process, the factors forming the competitiveness of these budgetary institutions play an important role from the point of view of survival. The more competitive a higher education institution is, the greater the chance is that the students would like to continue their studies there and thus this institution will have a greater chance for the survival in the future, compared to ones lagging behind in the competition. Aim of our treatise prepared is to present the current situation and main data of the EU higher education and we examine the performance of higher education: to what extent it fulfils the strategy for smart, sustainable and inclusive growth which is worded in the framework of Europe 2020 programme. The treatise is based on analysis of statistical data.

Making User-Generated Content Communities Work in Higher Education - The Importance of Setting Incentives

Science.gov (United States)

Vom Brocke, Jan; White, Cynthia; Walker, Ute; Vom Brocke, Christina

The concept of User-Generated Content (UGC) offers impressive potential for innovative learning and teaching scenarios in higher education. Examples like Wikipedia and Facebook illustrate the enormous effects of multiple users world-wide contributing to a pool of shared resources, such as videos and pictures and also lexicographical descriptions. Apart from single examples, however, the systematic use of these virtual technologies in higher education still needs further exploration. Only few examples display the successful application of UGC Communities at university scenarios. We argue that a major reason for this can be seen in the fact that the organizational dimension of setting up UGC Communities has widely been neglected so far. In particular, we indicate the need for incentive setting to actively involve students and achieve specific pedagogical objectives. We base our study on organizational theories and derive strategies for incentive setting that have been applied in a practical e-Learning scenario involving students from Germany and New Zealand.

Gooding, S K

1995-01-01

The research presented focuses on an examination of the relative importance of word-of-mouth, expert opinion, external communication, and past experience in the context of hospital choice. Past research has examined the effect of each individually and various combinations of the four sources, but not all four simultaneously. Results of the present study suggest that past experience plays a greater role in hospital choice than other information sources, including expert opinion. The strength of word-of-mouth as a source of information is also verified. The implications of this research include the following: (1) health care researchers need to incorporate word-of-mouth when investigating informations sources, and (2) local hospitals need to be aware of "negative perceptions" and strive for consumer satisfaction. Health care delivery systems incorporating consumer-based choice render these findings especially valuable as researchers and practitioners address the challenges that these evolving systems will bring.

Full Text Available The social networks have been growing steadily in recent years. Facebook, one of the most popular social networks, is a modern means of communication and socialization that has taken lately more ground in higher education becoming an important academic tool in the communication process. Many universities have their own Facebook page, being used by both students and teachers, and creating Facebook groups increasingly facilitates communication with students. Thus, this paper aims to identify the importance that Facebook holds in the academic communication process and highlights the implications it has in higher education. The results reveal that this type of communication has gained more ground in academia creating real social communities, and students use it more and more for collaboration in various activities involved in the higher education system, but also for socializing and information.

Microbial production of methane is an important terminal metabolic process during organic matter degradation in marine sediments. It is generally acknowledged that hydrogenotrophic and acetoclastic methanogenesis constitute the dominant pathways of methane production; the importance of methanogenesis from methylated compounds remains poorly understood. We conducted various biogeochemical and molecular genetic analyses to characterize substrate availability, rates of methanogenesis, and methanogen community composition, and further evaluated the contribution of different substrates and pathways for methane production in deltaic surface and subsurface sediments of the Western Mediterranean Sea. Major substrates representing three methanogenic pathways, including H2, acetate, and methanol, trimethylamine (TMA), and dimethylsulfide (DMS), were detected in the pore waters and sediments, and exhibited variability over depth and between sites. In accompanying incubation experiments, methanogenesis rates from various 14C labeled substrates varied as well, suggesting that environmental factors, such as sulfate concentration and organic matter quality, could significantly influence the relative importance of individual pathway. In particular, methylotrophic and hydrogenotrophic methanogenesis contributed to the presence of micromolar methane concentrations in the sulfate reduction zone, with methanogenesis from methanol accounting for up to 98% of the total methane production in the topmost surface sediment. In the sulfate-depleted zone, hydrogenotrophic methanogenesis was the dominant methanogenic pathway (67-98%), and enhanced methane production from acetate was observed in organic-rich sediment (up to 31%). Methyl coenzyme M reductase gene (mcrA) analysis revealed that the composition of methanogenic communities was generally consistent with the distribution of methanogenic activity from different substrates. This study provides the first quantitative assessment of

Relative importance of habitat area and isolation for bird occurrence patterns in a naturally patchy landscape

Wilson, T.L.; Johnson, E.J.; Bissonette, J.A.

2009-01-01

There is debate among ecologists about whether total habitat area or patch arrangement contributes most to population and/or community responses to fragmented or patchy landscapes. We tested the relative effects of patch area and isolation for predicting bird occurrence in a naturally patchy landscape in the Bear River Mountains of Northern Utah, USA. We selected focal patches (mountain meadows) ranging in elevation from 1,920 to 2,860 m and in size from 0.6 to 182 ha. Breeding birds were sampled in each focal meadow during the summers of 2003 and 2004 using variable-distance point transects. Logistic regression and likelihood-based model selection were used to determine the relationship between likelihood of occurrence of three bird species (Brewer's sparrow, vesper sparrow, and white-crowned sparrow) and area, isolation, and proximity metrics. We used model weights and model-averaged confidence intervals to assess the importance of each predictor variable. Plots of area versus isolation were used to evaluate complex relationships between the variables. We found that meadow area was the most important variable for explaining occurrence for two species, and that isolation was the most important for the other. We also found that the absolute distance was more appropriate for evaluating isolation responses than was the species-specific proximity metric. Our findings add clarity to the debate between ecologists regarding the relative importance of area and isolation in species responses to patchy landscapes.

Importance of Women's Relative Socioeconomic Status within Sexual Relationships in Communication about Safer Sex and HIV/STI Prevention.

Science.gov (United States)

Muchomba, Felix M; Chan, Christine; El-Bassel, Nabila

2015-06-01

The socioeconomic status (SES) of women is increasingly considered an important factor for HIV/STI risk. The HIV/STI literature has largely focused on women's absolute levels of SES, and therefore, the importance of their SES relative to their male sexual partners remains understudied. This paper examines the association between women's relative SES and frequency of safer sex communication among heterosexual couples. A convenience sample of 342 couples (N = 684) recruited in New York City was asked about frequency of discussions with their partner about the need to use male condoms, about HIV prevention, and about STI prevention in the previous 90 days. Differences between partners in education, income, employment, housing, and incarceration history were combined using principal component analysis to form an index of women's relative SES. Negative binomial regression models assessed associations between woman's relative SES and communication frequency controlling for age, sex, race, ethnicity, education, and relationship type using a generalized estimating equation framework. On average, participants had 2.5, 4.2, and 4.8 discussions regarding the need to use male condoms, about HIV prevention, and about STI prevention, respectively. A one standard deviation increase in a woman's relative SES score was associated with increased frequency of discussions about male condom use (adjusted rate ratio [aRR], 1.15; 95% confidence interval [CI], 1.03-1.29), about HIV prevention (aRR, 1.25; CI, 1.14-1.37), and about STI prevention (aRR, 1.29; CI, 1.18-1.41). Women's relative SES may be an important factor for sexual communication, and further research on its role in HIV/STI risk may uncover avenues for intervention.

The increasing importance of genomic information in clinical care heightens the need to examine how individuals understand, value, and communicate about this information. Based on a conceptual framework of genomics-related health literacy, we examined whether health literacy was related to knowledge, self-efficacy, and perceived importance of genetics and family health history (FHH) and communication about FHH in a medically underserved population. The analytic sample was composed of 624 patients at a primary care clinic in a large urban hospital. About half of the participants (47%) had limited health literacy; 55% had no education beyond high school, and 58% were Black. In multivariable models, limited health literacy was associated with lower genetic knowledge (β = -0.55, SE = 0.10, p interval [CI; 0.28, 0.90], p = .020), and greater perceived importance of genetic information (OR = 1.95, 95% CI [1.27, 3.00], p = .0022) but lower perceived importance of FHH information (OR = 0.47, 95% CI [0.26, 0.86], p = .013) and more frequent communication with a doctor about FHH (OR = 2.02, 95% CI [1.27, 3.23], p = .0032). The findings highlight the importance of considering domains of genomics-related health literacy (e.g., knowledge, oral literacy) in developing educational strategies for genomic information. Health literacy research is essential to avoid increasing disparities in information and health outcomes as genomic information reaches more patients.

Age-related changes in functional postsynaptic nicotinic acetylcholine receptor subunits in neurons of the laterodorsal tegmental nucleus, a nucleus important in drug addiction.

Science.gov (United States)

Christensen, Mark H; Kohlmeier, Kristi A

2016-03-01

The earlier an individual initiates cigarette smoking, the higher the likelihood of development of dependency to nicotine, the addictive ingredient in cigarettes. One possible mechanism underlying this higher addiction liability is an ontogenetically differential cellular response induced by nicotine in neurons mediating the reinforcing or euphoric effects of this drug, which could arise from age-related differences in the composition of nicotinic acetylcholine receptor (nAChR) subunits. In the current study, we examined whether the subunit composition of nAChRs differed between neurons within the laterodorsal tegmentum (LDT), a nucleus importantly involved in drug addiction associated behaviours, across two periods of ontogeny in which nicotine-mediated excitatory responses were shown to depend on age. To this end, whole-cell patch-clamp recordings in mouse brain slices from identified LDT neurons, in combination with nAChR subunit-specific receptor antagonists, were conducted. Comparison of the contribution of different nAChR subunits to acetylcholine (ACh)-induced inward currents indicated that the contributions of the β2 and/or β4 and α7 nAChR subunits alter across age. Taken together, we conclude that across a limited ontogenetic period, there is plasticity in the subunit composition of nAChRs in LDT neurons. In addition, our data indicate, for the first time, functional presence of α6 nAChR subunits in LDT neurons within the age ranges studied. Changes in subunit composition of nAChRs across ontogeny could contribute to the age-related differential excitability induced by nicotine. Differences in the subunit composition of nAChRs within the LDT would be expected to contribute to ontogenetic-dependent outflow from the LDT to target regions, which include reward-related circuitry. © 2014 Society for the Study of Addiction.

Trust-Building in Electronic Markets: Relative Importance and Interaction Effects of Trust-Building Mechanisms

Science.gov (United States)

Tams, Stefan

We examine the relative and complementary effectiveness of trust-building strategies in online environments. While prior research has examined various antecedents to trust, we investigated two trust-building mechanisms more in depth: Web site trust and vendor reputation. We tried to understand the relative effectiveness of these two important mechanisms to provide online businesses with a clear recommendation of how to establish trust in an effective and efficient manner. Drawing from the literature on trust, we proposed vendor reputation to be more effective than Web site trust. Moreover, we examined a potential complementary effect of these mechanisms so as to provide online businesses with a deeper understanding of how to derive superior trust. We hypothesize a small such effect. The study proposes a laboratory experiment to test the model.

Higher Order Loess Terracettes and Related Ungulate Activities in Western Pottawattamie County, Iowa

Science.gov (United States)

Weihs, B. J.

2009-12-01

Terracettes are small, quasi-parallel, staircase-like, stepped landforms. They are generally less than a meter in tread width and riser height and as long as 300 meters, located transversely along slopes. Many theories purport to explain the mechanisms that cause them, including animal disturbance, soil creep, solifluction (gelifluction), slumping and rotational slippage, regolith control, vegetation control, subsidence, and anthropogenic or tectonic activities. This thesis was aimed at morphologically characterizing terracettes in the western Iowa Loess Hills, with an emphasis on further classifying the forms morphogenetically. Onsite observations suggest that terracettes in this area are highly associated with anthropogenically induced grazing of domestic ungulates such as cattle, horses, and sheep, as well as deer. A new class of terracette (higher order or mega-terracette) is proposed that characterizes (and differentiates) the study area forms based on size, in that the study area contains terracettes that are an order above those discussed by other authors (sub-meter). This new addition to the current standard (tear terracettes-risers bare of vegetation, and normal terracettes-normal to the slope), as suggested by Anderson (1972), will add to the local understanding of the forms, and especially to the theory of polygenesis in which terracettes can result from a host of processes. This new class of terracette (mega) is higher magnitude, and directly related to ungulate activities such as geophagy, soil transport (from hooves), compaction, smearing, pawing, and wallowing (dust bathing) as well as the effects of variable soil moisture on erosion of the forms used by the animals.

Fuel Class Higher Alcohols

KAUST Repository

Sarathy, Mani

2016-08-17

This chapter focuses on the production and combustion of alcohol fuels with four or more carbon atoms, which we classify as higher alcohols. It assesses the feasibility of utilizing various C4-C8 alcohols as fuels for internal combustion engines. Utilizing higher-molecular-weight alcohols as fuels requires careful analysis of their fuel properties. ASTM standards provide fuel property requirements for spark-ignition (SI) and compression-ignition (CI) engines such as the stability, lubricity, viscosity, and cold filter plugging point (CFPP) properties of blends of higher alcohols. Important combustion properties that are studied include laminar and turbulent flame speeds, flame blowout/extinction limits, ignition delay under various mixing conditions, and gas-phase and particulate emissions. The chapter focuses on the combustion of higher alcohols in reciprocating SI and CI engines and discusses higher alcohol performance in SI and CI engines. Finally, the chapter identifies the sources, production pathways, and technologies currently being pursued for production of some fuels, including n-butanol, iso-butanol, and n-octanol.

Relative importance of professional practice and engineering management competencies

Science.gov (United States)

Pons, Dirk

2016-09-01

Problem: The professional practice of engineering always involves engineering management, but it is difficult to know what specifically to include in the undergraduate curriculum. Approach: The population of New Zealand practising engineers was surveyed to determine the importance they placed on specific professional practice and engineering management competencies. Findings: Results show that communication and project planning were the two most important topics, followed by others as identified. The context in which practitioners use communication skills was found to be primarily with project management, with secondary contexts identified. The necessity for engineers to develop the ability to use multiple soft skills in an integrative manner is strongly supported by the data. Originality: This paper is one of only a few large-scale surveys of practising engineers to have explored the soft skill attributes. It makes a didactic contribution of providing a ranked list of topics which can be used for designing the curriculum and prioritising teaching effort, which has not previously been achieved. It yields the new insight that combinations of topics are sometimes more important than individual topics.

Revenues from oil exports are an important part of government budgets in Mexico. A time-series analysis is conducted using monthly data from 1990 to 2005 examining three different specifications to determine how international oil price fluctuations and government income generated from oil exports influence fiscal policy in Mexico. The behavior of government spending and taxation is consistent with the spend-tax hypothesis. The results show that there is an inverse relationship between oil-related revenues and tax revenue from non-oil sources. Fiscal policy reform is urgently needed in order to improve tax collection as oil reserves in Mexico become more and more depleted. (author)

The log ft-values, the spectrum shape functions, and the beta-gamma angular correlation coefficients of the 170 Tm beta decay are computed in the framework of relativistic formfactor formalism using asymmetric rotor model wavefunctions. Main vector and axial vector hadron currents being strongly hindered, the relative importance of induced interaction matrix elements is accurately estimated. Good agreement with experiment is obtained for the beta decay observables when the main induced interaction terms were taken into account. The contribution of the pseudoscalar term was found insignificant. (authors)

Relative importance of dissolved and food pathways for lead contamination in shrimp

Energy Technology Data Exchange (ETDEWEB)

Boisson, F.; Cotret, O.; Teyssie, J.-L.; El-Baradeie, M.; Fowler, S.W

2003-12-01

The relative importance of dissolved and food pathways and the influence of food type in the bioaccumulation and retention of lead in the shrimp Palaemonetes varians were examined using a radiotracer method. Shrimp were exposed to {sup 210}Pb-labelled seawater or fed two types of {sup 210}Pb-labelled food, viz. mussels or worms. The amount of radiotracer accumulated by shrimp was examined over a 7-day period, followed by a 1-month and a 7-day depuration period for the dissolved and food source, respectively. Steady state in the uptake was reached after 2 days exposure to dissolved lead, with a resultant estimated concentration factor of 98 {+-} 3. Transfer factors following ingestion of contaminated mussels and worms were lower than unity for both food types, with lead transfer from worms being significantly higher than that from mussels. Accumulation of dissolved Pb by shrimp was found to occur mainly through adsorption on the exoskeleton with a minor accumulation in the internal tissues probably resulting from the intake of seawater for osmoregulation. In contrast, lead taken up from contaminated food was readily absorbed and bound in the internal tissues of P. varians. Although the transfer of lead to P. varians through the ingestion of contaminated food was low (TF < 1%), it still represented 4 to 8% of the lead content in the prey which is a significant additional contribution of lead to the shrimp body burden. Independent of food type, following ingestion of contaminated food, approximately 23-27% of total lead accumulated in shrimp was located in the edible parts (e.g. muscle). Therefore, the food pathway is suggested to be a significant contributor to the lead transfer to humans through ingestion of contaminated shrimp. After exposure to contaminated food, lead loss kinetics were described by a two-component model, whereas Pb loss following direct uptake from seawater was best described by a three-component model.

Object relations theories emphasize the manner in which the salience/importance of implicit representations of self and other guide interpersonal functioning. Two studies and a pilot test (total N = 304) sought to model such representations. In dyadic contexts, the self is a "you" and the other is a "me", as verified in a pilot test. Study 1 then used a simple categorization task and found evidence for implicit self-importance: The pronoun "you" was categorized more quickly and accurately when presented in a larger font size, whereas the pronoun "me" was categorized more quickly and accurately when presented in a smaller font size. Study 2 showed that this pattern possesses value in understanding individual differences in interpersonal functioning. As predicted, arrogant people scored higher in implicit self-importance in the paradigm. Findings are discussed from the perspective of dyadic interpersonal dynamics.

Full Text Available The aim of the paper is to raise awareness of the importance of the policy makers’ knowledge and expertise about quality infrastructure (QI for the successful policy-making. This article, which addresses the role of higher education in Serbian quality infrastructure policy-making, is an analysis of QI related contents of higher education institution curriculum. The target institutions are public faculties from whose official websites the data were collected. Depending on the keywords, the analysis was performed in order to classify the faculties into three categories. After reviewing the 307 subject titles and descriptions of undergraduate courses, the results show that the concepts of QI are widely recognized as an important and popular topic. The analysis of the QI adoption and diffusion indicates that although some of the faculties might be ‘leaders’ in a particular dimension, they still do not necessarily fall into the ‘leader’ category.

Unintentional injuries cause much of the global mortality burden, with the workplace being a common accident setting. Even in high-income economies, occupational injury figures remain remarkably high. Because risk factors for occupational injuries are prone to confounding, the present research takes a comprehensive approach. To better understand the occurrence of occupational injuries, sociodemographic factors and work- and health-related factors are tested simultaneously. Thus, the present analysis aims to develop a comprehensive epidemiological model that facilitates the explanation of varying injury rates in the workplace. The representative phone survey German Health Update 2010 provides information on medically treated occupational injuries sustained in the year prior to the interview. Data were collected on sociodemographics, occupation, working conditions, health-related behaviors, and chronic diseases. For the economically active population (18-70 years, n = 14,041), the 12-month prevalence of occupational injuries was calculated with a 95% confidence interval (CI). Blockwise multiple logistic regression was applied to successively include different groups of variables. Overall, 2.8% (95% CI 2.4-3.2) of the gainfully employed population report at least one occupational injury (women: 0.9%; 95% CI 0.7-1.2; men: 4.3%; 95% CI 3.7-5.0). In the fully adjusted model, male gender (OR 3.16) and age 18-29 (OR 1.54), as well as agricultural (OR 5.40), technical (OR 3.41), skilled service (OR 4.24) or manual (OR 5.12), and unskilled service (OR 3.13) or manual (OR 4.97) occupations are associated with higher chances of occupational injuries. The same holds for frequent stressors such as heavy carrying (OR 1.78), working in awkward postures (OR 1.46), environmental stress (OR 1.48), and working under pressure (OR 1.41). Among health-related variables, physical inactivity (OR 1.47) and obesity (OR 1.73) present a significantly higher chance of occupational injuries

Comparisons of Organic Carbon Analyzers and Related Importance to Water Quality Assessments

Full Text Available This study tested whether analyzers using different methods were equally capable of measuring organic carbon in diverse environmental water samples from California’s Sacramento/San Joaquin Delta and its watersheds. The study also evaluated whether the different instruments might provide differing organic carbon concentration measurements, which could in turn trigger (or not a regulatory requirement for enhanced coagulation at a water treatment plant. In Phase 1, samples were collected in eight monthly events at five stations associated with California’s State Water Project and analyzed using three high temperature combustion and three chemical oxidation instruments. Significant differences between instruments occurred in only 20% of the analyses. However, 80% of the observed differences were attributed to one combustion instrument that reported higher values compared to the other instruments. In Phase 2, four certified standards were analyzed with nine instruments. Results suggested that the main contributor of the observed differences was some instruments’ inability to remove inorganic carbon, an important step in the analytical process. There were no significant differences in the frequencies at which different instruments would have prescribed enhanced coagulation at a water treatment plant. We concluded that properly operating instruments using any of the standard methods were equally capable of analyzing the diverse concentration levels of organic carbon in the Delta.

Ticks imported to Europe with exotic reptiles.

Science.gov (United States)

Mihalca, Andrei Daniel

2015-09-30

It is known that traded exotic animals carry with them an immense number of associated symbionts, including parasites. Reptiles are no exception. Most of the imported reptiles originate from tropical countries and their possibility to carry potentially dangerous pathogens is high. According to CITES, Europe is currently the main reptile importer in the world. Despite this, there is no review or analysis available for the risk related to the importation of tick-borne diseases with traded reptile to the EU. The main aim of the manuscript is to provide a review on the available literature on ticks introduced to and exchanged between European countries via the live reptile trade. So far, the published reports of ticks imported on reptiles are limited to few European countries: Italy, Poland, Spain, Netherlands, Belgium, Slovenia and UK. The following species have been reported: Hyalomma aegyptium, Amblyomma dissimile, Amblyomma exornatum, Amblyomma flavomaculatum, Amblyomma fuscolineatum, Amblyomma latum, Amblyomma quadricavum, Amblyomma marmoreum, Amblyomma nuttalli, Amblyomma sparsum, Amblyomma sphenodonti, Amblyomma transversale and Amblyomma varanense. The majority of species are of African origin, followed by American and Asian species. All groups of reptiles (chelonians, snakes, lizards, crocodiles, tuataras) were involved. However, it seems that certain groups (i.e. tortoises of genus Testudo, monitor lizards of genus Varanus, snakes of genus Python) are more important as host for imported ticks, but this may be related to higher levels of international trade. Even fewer are the reports of tick-borne pathogens associated with imported reptile ticks. Despite the diversity of tick species reported on imported reptiles, the situations of truly invasive species are atypical and are limited in natural environments to maximum two cases where H. aegyptium was involved. Otherwise, the risk associated with reptile trade for introduction of invasive tick to Europe is low

A Variety of Diversity: Facing Higher Education's Educational Challenges

Dey, Eric L.

2008-10-01

First among the many important challenges facing American higher education is the need to improve the effectiveness of our educational programs. Public concern has heightened the sense of urgency for colleges and universities to make progress on improving and measuring educational outcomes, which is made more challenging by the varieties of diversity facing us. Diversity is not just an issue related to student recruitment or experience, but rather it is one that also relates to institutions and their faculties. New educational methods must address such diversity to be effective, and one possible example can be found in ongoing research at the University of Michigan that explores the educational implications of implementing a web-based lecture capture system in large lecture courses. Student use of and reactions to such systems is important, as is the potential to influence course performance for students in general, but also for underrepresented and at-risk student subpopulations. In addition to helping bring our current landscape into focus, this paper will identify effective practices as well as continuing challenges to improving educational practice for undergraduate students.

Sorption of phenanthrene and benzene on differently structural kerogen: Important role of micropore-filling

International Nuclear Information System (INIS)

Zhang, Yulong; Ma, Xiaoxuan; Ran, Yong

2014-01-01

Shale was thermally treated to obtain a series of kerogen with varied maturation. Their chemical, structural and porous properties were related to the sorption and/or desorption behaviors of phenanthrene and benzene. As the treatment temperature increases, aliphatic and carbonyl carbon of the kerogen samples decrease, while their aromaticity and maturation increase. Meanwhile, the isothermal nonlinearity of phenanthrene and benzene increases whereas the sorption capacity and micropore adsorption volumes (V o,d ) initially increase and then decrease. The V o,d of benzene is significantly correlated with, but higher than that of phenanthrene, suggesting similar micropore filling mechanism and molecular sieve effect. The benzene desorption exhibits hysteresis, which is related to the pore deformation of the kerogen and the entrapment of solute in the kerogen matrix. The V o,d of phenanthrene and benzene on the kerogen samples accounts for 23–46% and 36–65% of the maximum sorption volumes, respectively, displaying the importance of the micropore filling. -- Highlights: • The microporosity estimated by benzene vapor differs greatly from that by N 2 . • The micropore volume changes with kerogen maturation. • The phenanthrene or benzene sorption is related to the microporosity of kerogen. • Higher adsorption volume for benzene than for phenanthrene suggests molecular sieve effect. • The pore-filling plays an important role in the sorption of phenanthrene and benzene. -- The sorption behaviors of benzene and phenanthrene are related to the microporosity of the differently matured kerogen, indicating the importance of pore-filling

2012-01-01

To examine the incidence and risk factors of firework-related injuries during the Last Wednesday Eve Festival in Tehran, Iran, with a focus on the association of socio-economic status and educational level with the use of fireworks and the incidence of firework-related injury. Cross-sectional household survey. Using a random cluster sampling approach, a household survey was conducted in Greater Tehran in April 2008. During a structured interview with an adult member of the household, questions were asked about the use of fireworks and any firework-related injuries sustained by household members during the preceding festival. Data were gathered on expenditure on fireworks, medical treatment of firework-related injuries, length of hospital stay for the treatment of these injuries, and damage to personal property by fireworks. The survey included 2456 households in Greater Tehran. At least one member of 18% of these households had used fireworks during the Last Wednesday Eve Festival in 2008. The overall incidence of firework-related injuries was 100 per 100,000 population (95% confidence interval 37-163). The use of fireworks was less common among parents and more common among male children. Individuals who used fireworks were younger than non-users. Younger age and use of fireworks were associated with firework-related injuries (P fireworks was US$1.62. Among the households that had bought fireworks, the mean expenditure was US$9.40 (standard deviation US$16.34). Thirty-two households (1.3%) reported damage to personal property due to fireworks during the festival costing US$3.30-167.20. The regional price of housing in the study area was correlated with the educational level of the head of the household. Higher educational level of the head of the household was associated with participation in firework activities by household members, expenditure on fireworks, and the amount of financial loss due to fireworks (all P Fireworks are associated with serious injuries

2015-11-01

Pediatric scald burns result in frequent emergency room visits and hospitalizations. We investigated whether cooking-related burns produce greater morbidity requiring more extensive care than noncooking burns. We performed a 6-y review at our free-standing children's hospital. Children aged cooking versus noncooking burns. The Mann-Whitney U test, a chi-square test, and the negative binomial were used to compare continuous, categorical, and count data between groups. Bivariate analysis was performed to identify risk factors among patients with adverse outcomes. We identified 308 patients; 262 (85%) cooking and 46 (15%) noncooking burns. Most patients were African-American males, with public insurance, and a median age of 2 y. Cooking burns preferentially occurred over the head, neck, and upper body; noncooking burns were distributed over the lower body (P  0.11). In subgroup analysis, semisolid and grease burns resulted in increased rates of wound contractures and/or limited mobility when compared with noncooking burns (P = 0.05 and P = 0.008, respectively). Patients with complications were more likely to have third degree burns and required more consults, longer hospitalization, and more surgical debridements and clinic visits. Most accidental scald burns occurred in young children during food preparation. Greater long-term morbidity was found in patients with semisolid and grease burns. This subset of children has a higher injury burden and requires extensive care in the acute and long-term setting. Copyright © 2015 Elsevier Inc. All rights reserved.

Atmospheric River Importance to Extratropical Climate and Hydrology

Science.gov (United States)

Nash, D.; Waliser, D. E.; Guan, B.; Ye, H.; Ralph, F. M.

2017-12-01

Atmospheric Rivers (ARs) are narrow, long, water vapor rich corridors of the atmosphere that are responsible for over 90% of the poleward moisture transport across mid-latitudes and into high latitudes. This suggests a crucial role for ARs in helping establish the extra-tropical atmospheric water budget and hydroclimate variability. However, the contribution of ARs to the extra-tropical atmospheric water budget has yet to be quantified, including impacts on water vapor transport and storage, and precipitation. This study characterizes the roles of AR related atmospheric transport on combined and individual atmospheric water budget variables over extratropical regions of both hemispheres based on MERRA2 reanalysis products during 1997-2014. Results show that poleward water vapor transport related to ARs is strongly related to changes in water vapor storage and especially precipitation in higher latitudes in both hemispheres, with the relationship dependent on averaging period. For example, for the annual cycle climatology, both AR transport and local evaporation support the variation in precipitation. However, on monthly time scales, the water budget at higher latitudes tends to be dominated by the balance between AR transport and precipitation. On pentad and daily time scales, AR transport is related to both precipitation and water vapor storage changes. These results indicate the important role of the episodic, extreme moisture transports associated with ARs in helping establish the high latitude water and energy cycles, and associated hydroclimate.

An analysis was undertaken to establish preliminary trends for how component aging can effect failure rates for swing check valves, centrifugal pumps and motor operated valves. These failure rate trends were evaluated over time and linear aging rate models established. The failure rate models were then used with classic reliability theories to estimate reliability as a function of operating time. Reliability theory was also used to establish a simple system reliability model. Using the system model, the relative importance of pumps and valves to the overall system reliability were studied. Conclusions were established relative to overall system availability over time and the relative unavailabilities of the various components studied.

1980-01-01

Higher-order corrections to deep inelastic and inclusive annihilation processes in the asymptotically free (PHI 3 ) 6 theory are calculated by using the method of cut vertices proposed by Mueller. Renormalization of the cut vertices is carried out up the two-loop level and it is found that, in the minimal subtraction scheme, the equality between the anomalous dimension of the space-like cut vertex and that of the corresponding time-like cut vertex does not hold beyond the leading order. Corrections to the coefficient functions are also calculated to study the Q 2 dependence of the moment up to the next-to-leading order. It is shown that the reciprocity relation suggested by Gribov and Lipatov on the basis of the leading-order calculation does not hold in the higher order. (orig.)

Adhesive systems: important aspects related to their composition and clinical use

Mario Honorato Silva e Souza Junior

2010-06-01

Full Text Available This literature review article addresses the types and the main components of different etch-and-rinse and self-etch adhesive systems available in the market, and relates them to their function, possible chemical interactions and infuence of handling characteristics. Scanning electron microscopy (SEM images are presented to characterize the interface between adhesives and dentin. Adhesive systems have been recently classifed according to their adhesion approaches in etch-and-rinse, self-etch and glass ionomer. The etch-and-rinse systems require a specifc acid-etch procedure and may be performed in two or three steps. Self-etch systems employ acidic monomers that demineralize and impregnate dental substrates almost at the same time. These systems are separated in one or two steps. Some advantages and defciencies were noted for etch-and-rinse and self-etch approaches, mainly for the simplifed ones due to some chemical associations and interactions. The SEM micrographs illustrate different relationships between adhesive systems and dental structures, particularly dentin. The knowledge of composition, characteristics and mechanisms of adhesion of each adhesive system is of fundamental importance to permit the adoption of ideal bonding strategies under clinical conditions.

The relative importance of family socioeconomic status and school-based peer hierarchies for morning cortisol in youth: an exporatory study.

West, Patrick; Sweeting, Helen; Young, Robert; Kelly, Shona

2010-04-01

This paper examines the relative importance of family socioeconomic status (SES) and school-based peer hierarchies for young people's psychoneuroendocrine response, represented by cortisol level. Data are drawn from a study of 2824, 15-year-olds in 22 Scottish secondary schools in 2006 who provided information on family SES (parental occupation, material deprivation and family affluence) and social position in school hierarchies, together with two morning salivary cortisol samples. School social position was assessed by participants placing themselves on seven 'ladders', from which three factors were derived, termed scholastic, peer and sports hierarchies. Controlling for confounds, there was little or no variation in cortisol by any SES measure. By contrast, each school hierarchy was independently associated with cortisol, but in different ways. For the scholastic hierarchy, an inverse linear relationship was found for females, cortisol increasing with lower position. For peer hierarchy, an opposite (direct) linear relationship occurred for males, while for females elevated cortisol was associated only with 'top' position. For sports, elevated cortisol among males was associated with 'bottom' position, among females with all except the 'top'. These results are interpreted in the context of Sapolsky's (Sapolsky, 2005) predictions for stress responses to hierarchical position in stable and unstable social systems, the former represented by the scholastic hierarchy involving elevated cortisol in lower positions, the latter by peer hierarchy with elevated cortisol in higher positions. Overall, the results highlight the greater importance of school-based peer groups than family SES for young people's psychoneuroendocrine response. Copyright 2010 Elsevier Ltd. All rights reserved.

Full Text Available ABSTRACT: Enterotoxigenic Escherichia coli (ETEC is the major cause of diarrhea in newborn and weaned pigs. Bacteria adhesion to the host cell is considered a specific phenomenon among fimbrial and non-fimbrial adhesins with their respective receptors on enterocytes. Enteric disorders are related with the fimbriae F4 (K88, F5 (K99, F6 (987P, F41, and F18. In addition to ETEC, another category of E. coli , porcine pathogenic E. coli (PEPEC,can cause diarrhea in pigs; it produces the porcine attaching and effacing-associated (Paa adhesin in, which is capable to cause a typical lesion known as an attaching and effacing (A/E lesion. Immunization of sows with adhesin is important to stimulate the production of antibodies and their subsequent transfer to piglets through colostrum. The aim of this paper is to illustrate the main impacts of enteric diseases caused by E. coli in swine production and to highlight the importance of continuing research on this bacterium to improve disease prevention through vaccination.

Full Text Available Unintentional injuries cause much of the global mortality burden, with the workplace being a common accident setting. Even in high-income economies, occupational injury figures remain remarkably high. Because risk factors for occupational injuries are prone to confounding, the present research takes a comprehensive approach. To better understand the occurrence of occupational injuries, sociodemographic factors and work- and health-related factors are tested simultaneously. Thus, the present analysis aims to develop a comprehensive epidemiological model that facilitates the explanation of varying injury rates in the workplace. The representative phone survey German Health Update 2010 provides information on medically treated occupational injuries sustained in the year prior to the interview. Data were collected on sociodemographics, occupation, working conditions, health-related behaviors, and chronic diseases. For the economically active population (18-70 years, n = 14,041, the 12-month prevalence of occupational injuries was calculated with a 95% confidence interval (CI. Blockwise multiple logistic regression was applied to successively include different groups of variables. Overall, 2.8% (95% CI 2.4-3.2 of the gainfully employed population report at least one occupational injury (women: 0.9%; 95% CI 0.7-1.2; men: 4.3%; 95% CI 3.7-5.0.

The risk of gestational diabetes mellitus (GDM) increases substantially with increasing maternal body mass index (BMI). The aim of the present study was to evaluate the relative importance of maternal BMI and glucose levels in prediction of large-for-gestational-age (LGA) births. This observational cohort study was based on women giving birth in southern Sweden during the years 2003-2005. Information on 10,974 pregnancies was retrieved from a population-based perinatal register. A 75-g oral glucose tolerance test (OGTT) was performed in the 28 week of pregnancy for determination of the 2-h plasma glucose concentration. BMI was obtained during the first trimester. The dataset was divided into a development set and a validation set. Using the development set, multiple logistic regression analysis was used to identify maternal characteristics associated with LGA. The prediction of LGA was assessed by receiver-operating characteristic (ROC) curves, with LGA defined as birth weight > +2 standard deviations of the mean. In the final multivariable model including BMI, 2-h glucose level and maternal demographics, the factor most strongly associated with LGA was BMI (odds ratio 1.1, 95% confidence interval [CI] 1.08-1.30). Based on the total dataset, the area under the ROC curve (AUC) of 2-h glucose level to predict LGA was 0.54 (95% CI 0.48-0.60), indicating poor performance. Using the validation database, the AUC for the final multiple model was 0.69 (95% CI 0.66-0.72), which was identical to the AUC retrieved from a model not including 2-h glucose (0.69, 95% CI 0.66-0.72), and larger than from a model including 2-h glucose but not BMI (0.63, 95% CI 0.60-0.67). Both the 2-h glucose level of the OGTT and maternal BMI had a significant effect on the risk of LGA births, but the relative contribution was higher for BMI. The findings highlight the importance of concentrating on healthy body weight in pregnant women and closer monitoring of weight during pregnancy as a

Experiencing romantic love is important in individual development. Little is known about romantic love among adolescents in non-Western countries. The aim of the present study was to explore romantic love among Iranian male and female adolescents. A total of 201 adolescents (mean age: 17.73 years) took part in the study; of these, 81 indicated they were experiencing romantic love at the time of survey, and 120 indicated they were not in love. Participants answered questionnaires related to affective states (hypomania, depressive symptoms, state and trait anxiety) and exercise, and completed a sleep log for seven consecutive nights. Compared to controls, participants in love displayed favourable hypomania scores, fewer depressive symptoms and increased concentration during the day. However, participants in love also had higher state anxiety scores. Moreover, hypomanic-like stages increased with duration of relationship in female, but not in male participants. The pattern of results suggests a favourable association between being currently in love and emotional and cognitive processes. Sleep, however, seemed unrelated to this specific state.

Nonlinear higher-spin equations in four dimensions admit a closed two-form that defines a gauge-invariant global charge as an integral over a two-dimensional cycle. In this paper we argue that this charge gives rise to partitions depending on various lower- and higher-spin chemical potentials identified with modules of topological fields in the theory. The vacuum contribution to the partition is calculated to the first nontrivial order for a solution to higher-spin equations that generalizes AdS{sub 4} Kerr black hole of General Relativity. The resulting partition is non-zero being in parametric agreement with the ADM-like behavior of a rotating source. The linear response of chemical potentials to the partition function is also extracted. The explicit unfolded form of 4d GR black holes is given. An explicit formula relating asymptotic higher-spin charges expressed in terms of the generalized higher-spin Weyl tensor with those expressed in terms of Fronsdal fields is obtained.

This cross-sectional study aims to identify the predictors of work-related difficulties in a sample of employed persons with multiple sclerosis as addressed with the Multiple Sclerosis Questionnaire for Job Difficulties. Hierarchical linear regression analysis was conducted to identify predictors of work difficulties: predictors included demographic variables (age, formal education), disease duration and severity, perceived disability and psychological variables (cognitive dysfunction, depression and anxiety). The targets were the questionnaire's overall score and its six subscales. A total of 177 participants (108 females, aged 21-63) were recruited. Age, perceived disability and depression were direct and significant predictors of the questionnaire total score, and the final model explained 43.7% of its variation. The models built on the questionnaire's subscales show that perceived disability and depression were direct and significant predictors of most of its subscales. Our results show that, among patients with multiple sclerosis, those who were older, with higher perceived disability and higher depression symptoms have more and more severe work-related difficulties. The Multiple Sclerosis Questionnaire for Job Difficulties can be fruitfully exploited to plan tailored actions to limit the likelihood of near-future job loss in persons of working age with multiple sclerosis. Implications for rehabilitation Difficulties with work are common among people with multiple sclerosis and are usually addressed in terms of unemployment or job loss. The Multiple Sclerosis Questionnaire for Job Difficulties is a disease-specific questionnaire developed to address the amount and severity of work-related difficulties. We found that work-related difficulties were associated to older age, higher perceived disability and depressive symptoms. Mental health issues and perceived disability should be consistently included in future research targeting work-related difficulties.

Partitioning the Relative Importance of Phylogeny and Environmental Conditions on Phytoplankton Fatty Acids

Science.gov (United States)

Galloway, Aaron W. E.; Winder, Monika

2015-01-01

Essential fatty acids (EFA), which are primarily generated by phytoplankton, limit growth and reproduction in diverse heterotrophs. The biochemical composition of phytoplankton is well-known to be governed both by phylogeny and environmental conditions. Nutrients, light, salinity, and temperature all affect both phytoplankton growth and fatty acid composition. However, the relative importance of taxonomy and environment on algal fatty acid content has yet to be comparatively quantified, thus inhibiting predictions of changes to phytoplankton food quality in response to global environmental change. We compiled 1145 published marine and freshwater phytoplankton fatty acid profiles, consisting of 208 species from six major taxonomic groups, cultured in a wide range of environmental conditions, and used a multivariate distance-based linear model to quantify the total variation explained by each variable. Our results show that taxonomic group accounts for 3-4 times more variation in phytoplankton fatty acids than the most important growth condition variables. The results underscore that environmental conditions clearly affect phytoplankton fatty acid profiles, but also show that conditions account for relatively low variation compared to phylogeny. This suggests that the underlying mechanism determining basal food quality in aquatic habitats is primarily phytoplankton community composition, and allows for prediction of environmental-scale EFA dynamics based on phytoplankton community data. We used the compiled dataset to calculate seasonal dynamics of long-chain EFA (LCEFA; ≥C20 ɷ-3 and ɷ-6 polyunsaturated fatty acid) concentrations and ɷ-3:ɷ-6 EFA ratios in Lake Washington using a multi-decadal phytoplankton community time series. These analyses quantify temporal dynamics of algal-derived LCEFA and food quality in a freshwater ecosystem that has undergone large community changes as a result of shifting resource management practices, highlighting diatoms

Abstract Background High impact physical activity (PA) is thought to improve skeletal health, but its relation to other health outcomes are unclear. We investigated associations between PA impact magnitude and body mass index (BMI) in older adults. Methods Data were taken from the Cohort for Skeletal Health in Bristol and Avon (COSHIBA), Hertfordshire Cohort Study, and MRC National Survey of Health and Development. Vertical acceleration peaks from 7-day hip-worn accelerometer recordings were used to classify PA as low (0.5 impact. Cohort-specific associations of low, medium, and higher impact PA with BMI were examined using linear regressions and estimates combined using random-effects meta-analysis. Results A total of 1182 participants (mean age = 72.7 years, 68% female) were included. Low, medium, and higher impact PA were inversely related to BMI in initial models. After adjustment for confounders and other impacts, low, but not medium or higher, impacts were inversely related to BMI (−0.31, p impacts). In adjusted analyses of body composition measured by dual-energy X-ray absorptiometry in COSHIBA, low, but not medium or higher, impacts were inversely related to total body fat mass (−0.19, p impact PA was weakly and positively associated with lean mass (0.05, p = .06). Conclusions Greater exposure to PA producing low magnitude vertical impacts was associated with lower BMI and fat mass at older age. Low impact PA may help reduce obesity risk in older adults.

False memory and importance: can we prioritize encoding without consequence?

Bui, Dung C; Friedman, Michael C; McDonough, Ian M; Castel, Alan D

Given the large amount of information that we encounter, we often must prioritize what information we attempt to remember. Although critical for everyday functioning, relatively little research has focused on how people prioritize the encoding of information. Recent research has shown that people can and do selectively remember information assigned with higher, relative to lower, importance. However, the mechanisms underlying this prioritization process and the consequences of these processes are still not well understood. In the present study, we sought to better understand these prioritization processes and whether implementing these processes comes at the cost of memory accuracy, by increasing false memories. We used a modified form of the Deese/Roediger-McDermott (DRM) paradigm, in which participants studied DRM lists, with each list paired with low, medium, or high point values. In Experiment 1, encoding higher values led to more false memories than did encoding lower values, possibly because prioritizing information enhanced relational processing among high-value words. In Experiment 2, disrupting relational processing selectively reduced false memories for high-value words. Finally, in Experiment 3, facilitating relational processing selectively increased false memories for low-value words. These findings suggest that while prioritizing information can enhance true memory, this process concomitantly increases false memories. Furthermore, the mechanism underlying these prioritization processes depends on the ability to successfully engage in relational processing. Thus, how we prioritize the encoding of incoming information can come at a cost in terms of accurate memory.

How "fun/importance" fit affects performance: relating implicit theories to instructions.

Bianco, Amy T; Higgins, E Tory; Klem, Adena

2003-09-01

People experience a regulatory fit when they employ means of goal pursuit that fit their regulatory orientation, and this fit increases motivation that can enhance performance. The present studies extend previous research on regulatory fit to the classic motivational variables of fun and importance. They also examine for the first time the effect on performance of the fit between individuals' implicit theories about a task's fun or importance and their strategic engagement of the task as fun or important as induced by task instructions. In all three studies, task performance was better when the external task instructions "fit" rather than did not fit participants' implicit theory for the task. The implications of these findings for understanding the motivational effects of fun and importance are discussed.

Skilled attendance at delivery is an important indicator in monitoring progress towards Millennium Development Goal 5 to reduce the maternal mortality ratio by three quarters between 1990 and 2015. In addition to professional attention, it is important that mothers deliver their babies in an appropriate setting, where life saving equipment and hygienic conditions can also help reduce the risk of complications that may cause death or illness to mother and child. Over the past decade interest has grown in examining influences on care-seeking behavior and this study investigates the determinants of place of delivery in rural India, with a particular focus on assessing the relative importance of community access and economic status. A descriptive analysis of trends in place of delivery using data from two national representative sample surveys in 1992 and 1998 is followed by a two-level (child/mother and community) random-effects logistical regression model using the second survey to investigate the determinants. In this investigation of institutional care seeking for child birth in rural India, economic status emerges as a more crucial determinant than access. Economic status is also the strongest influence on the choice between a private-for-profit or public facility amongst institutional births. Greater availability of obstetric services will not alone solve the problem of low institutional delivery rates. This is particularly true for the use of private-for-profit institutions, in which the distance to services does not have a significant adjusted effect. In the light of these findings a focus on increasing demand for existing services seems the most rational action. In particular, financial constraints need to be addressed, and results support current trials of demand side financing in India.

The relative importance of seed competition, resource competition and perturbations on community structure

Directory of Open Access Journals (Sweden)

K. Bohn

2011-05-01

Full Text Available While the regional climate is the primary selection pressure for whether a plant strategy can survive, however, competitive interactions strongly affect the relative abundances of plant strategies within communities. Here, we investigate the relative importance of competition and perturbations on the development of vegetation community structure. To do so, we develop DIVE (Dynamics and Interactions of VEgetation, a simple general model that links plant strategies to their competitive dynamics, using growth and reproduction characteristics that emerge from climatic constraints. The model calculates population dynamics based on establishment, mortality, invasion and exclusion in the presence of different strengths of perturbations, seed and resource competition. The highest levels of diversity were found in simulations without competition as long as mortality is not too high. However, reasonable successional dynamics were only achieved when resource competition is considered. Under high levels of competition, intermediate levels of perturbations were required to obtain coexistence. Since succession and coexistence are observed in plant communities, we conclude that the DIVE model with competition and intermediate levels of perturbation represents an adequate way to model population dynamics. Because of the simplicity and generality of DIVE, it could be used to understand vegetation structure and functioning at the global scale and the response of vegetation to global change.

Poínhos, Rui; Oliveira, Bruno M P M; Correia, Flora

2013-12-01

Our aim was to determine prototypical patterns of eating behaviour among Portuguese higher education students, and to relate these patterns with BMI. Data from 280 higher education students (63.2% females) aged between 18 and 27 years were analysed. Several eating behaviour dimensions (emotional and external eating, flexible and rigid restraint, binge eating, and eating self-efficacy) were assessed, and eating styles were derived through cluster analysis. BMI for current, desired and maximum self-reported weights and the differences between desired and current BMI and between maximum and current BMI were calculated. Women scored higher in emotional eating and restraint, whereas men showed higher eating self-efficacy. Men had higher current, desired and maximum BMI. Cluster analysis showed three eating styles in both male and female subsamples: "Overeating", "High self-efficacy" and "High restraint". High self-efficacy women showed lower BMI values than the others, and restrictive women had higher lost BMI. High self-efficacy men showed lower desired BMI than overeaters, and lower maximum and lost BMI than highly restrictive ones. Restrictive women and men differ on important eating behaviour features, which may be the cause of differences in the associations with BMI. Eating self-efficacy seems to be a central variable influencing the relationships between other eating behaviour dimensions and BMI. Copyright © 2013 Elsevier Ltd. All rights reserved.

Evidence for higher-order effects in L-shell ionization by proton impact

It is widely believed that higher order processes of ion-atom collisions are negligible in cases of light projectiles like proton. Recent refined experiments tried to prove that the existence of such effects were comperable with the experimental errors, and they showed the unexpected relative importance of the higher order processes. Thus a new coupled channel calculation was performed for proton-gold atom collision in the energy range of 0.15-3.0 MeV, including dynamical subshell coupling effects. The results show that the deviations from the first order cross sections reach 40% at low collision energy. This result made necessary to correct the calculations of L-shell X-ray production cross sections. (D.G.) 6 refs

International mobility placements enable students and staff in Higher Education to enhance transversal and employability-related skills.

2015-10-01

Internationalization has commanded an ever-more prominent position in higher education over recent years, and is now firmly entrenched. While academia has long been outward looking-international research collaborations, conferences and student exchanges are well-established practices-it is relatively recently that internationalization has become a goal in its own right, rather than a consequence of normal academic activity. There are multiple interdependent drivers behind this: a focus on graduate employability and development of broad competencies and transferable skills in addition to subject-specific training, 'international awareness' being confirmed as a graduate attribute that is highly valued by employers, the availability of detailed information enabling prospective students to choose between Higher Education Institutions on the basis of their international opportunities and graduate employment rates, increasing competition between Institutions to attract the best students and to ascend national and international league tables, and (both driving and reflecting these trends) national policy frameworks. This minireview focuses on two aspects of internationalization of direct relevance to microbiology students and academic staff in a typical Higher Education Institution: student research placements overseas, and the impact of international mobility on teaching practice and the student experience. Practical strategies for developing intercultural awareness and enhancing employability are highlighted. © FEMS 2015. All rights reserved.

There has been an international emerging issue in the role of higher education in promoting sustainability due to numerous declarations and commitments related to the need of sustainability in higher education. As a result, there is an increasing number of higher educations that have embarked on projects and initiatives to incorporate sustainability into their systems. Higher educations could implement ISO 14001 framework that is recognized as a guide for an organization which aim to implement an environmental management system to pursue the sustainability. This research tried to attempt an extension of the previous work in assessing campus sustainability using ISO 14001 framework by integrating the analytic hierarchy process and importance-performance analysis (IPA). The inclusion of IPA is because many organizations are constrained by limitations on the resources they have so that it has to be decided how those limited resources are best deployed to attain the goals to be achieved. The self-assessment scores of ISO 14001 would the performance and the AHP result is the importance part of the IPA. A case study is conducted at the Diponegoro University, which is located in Semarang, Indonesia. The result indicates that only two main elements of ISO 14001 are located in the second quadrant of IPA, i.e. high performance and high importance. The result also could be a basis for the university to identify, prioritize, and improve the programs related to sustainability and ensure that valuable resources are allocated in the most effective areas.

This chapter discusses and reflects on the dilemmas and paradoxes of capacity building in African higher education by drawing on the findings of the case-based chapters in the book. The collection confirms the importance of using geography of knowledge as an approach for understanding how capacity...... building influences and affects African academics, institutions and degree programmes. The chapters also illustrate how reflexivity and positionality can be important tools for highlighting the power relations inherent in capacity building. In this chapter we discuss the three interwoven dilemmas...... neo-imperial effects of internationalisation.

I review recent work on the holographic relation between higher-spin theories in Anti-de Sitter spaces and conformal field theories. I present the main results of studies concerning the higher-spin holographic dual of the three-dimensional O(N) vector model. I discuss the special role played by certain double-trace deformations in Conformal Field Theories that have higher-spin holographic duals. Moreover, I show that duality transformations in a U(1) gauge theory on AdS 4 induce boundary double-trace deformations and argue that a similar effect takes place in the holography of linearized higher-spin theories on AdS 4 .

Resilience and Higher Order Thinking

Directory of Open Access Journals (Sweden)

Ioan Fazey

2010-09-01

Full Text Available To appreciate, understand, and tackle chronic global social and environmental problems, greater appreciation of the importance of higher order thinking is required. Such thinking includes personal epistemological beliefs (PEBs, i.e., the beliefs people hold about the nature of knowledge and how something is known. These beliefs have profound implications for the way individuals relate to each other and the world, such as how people understand complex social-ecological systems. Resilience thinking is an approach to environmental stewardship that includes a number of interrelated concepts and has strong foundations in systemic ways of thinking. This paper (1 summarizes a review of educational psychology literature on PEBs, (2 explains why resilience thinking has potential to facilitate development of more sophisticated PEBs, (3 describes an example of a module designed to teach resilience thinking to undergraduate students in ways conducive to influencing PEBs, and (4 discusses a pilot study that evaluates the module's impact. Theoretical and preliminary evidence from the pilot evaluation suggests that resilience thinking which is underpinned by systems thinking has considerable potential to influence the development of more sophisticated PEBs. To be effective, however, careful consideration of how resilience thinking is taught is required. Finding ways to encourage students to take greater responsibility for their own learning and ensuring close alignment between assessment and desired learning outcomes are particularly important.

Sustainable spatial development in higher education

Maja Terlević

2015-06-01

Full Text Available Sustainable development is not only a great challenge for society as a whole, but also for higher education institutions, which have been rapidly including sustainable development in their educational process in the last two decades. Directly or indirectly, education for sustainable spatial development includes all aspects of sustainable development: environmental, economic, social and cultural. Space is a junction of various interests, which requires coordinating the entire process of spatial planning, taking into account the goal of sustainable spatial development. The existing values of space are insufficient for the rapid implementation of a sustainable spatial development paradigm. Suitable education is needed by both individuals and spatial planning professionals and at all levels of education. It is therefore necessary to transform some of the academic programs in the higher education curriculum by integrating teaching content and methods that include long-term knowledge and holistic thinking, taking into account the importance of interdisciplinary integration. This article reviews literature in sustainable development in higher education from 2002 to 2013. Topics discussed include students’ and teachers’ conceptions of sustainable development, the presence of sustainable development and sustainable spatial development in higher education and the reasons for the slow introduction of this material into the curriculum. Based on a literature analysis, the last section identifies important drivers that can contribute to a more rapid integration of a sustainable spatial development paradigm into higher education.

Drawing from self-determination theory (Ryan & Deci, 2002, Overview of self-determination theory: An organismic-dialectical perspective. In E. L. Deci & R. M. Ryan (Eds.), Handbook of self-determination research (pp. 3-33). Rochester, NY: The University of Rochester Press.), we examined how individuals' psychological needs, motivation, and behaviours (i.e., physical activity and eating) associated with weight management could be predicted by perceptions of their important others' supportive and controlling behaviours. Using a cross-sectional survey design, 235 participants (mean age = 27.39 years, SD = 8.96 years) completed an online questionnaire. Statistical analyses showed that when important others were perceived to be more supportive, participants reported higher levels of more optimal forms of motivation for weight management, which in turn predicted more physical activity and healthy eating behaviours. In contrast, when important others were perceived to be controlling, participants reported higher levels of less optimal forms of motivation, which in turn predicted less physical activity and healthy eating behaviours, as well as more unhealthy eating behaviours. Significant indirect effects were also found from perceived support and control from important others to physical activity and eating behaviours, all in the expected directions. The findings support the importance of important others providing support and refraining from controlling behaviours in order to facilitate motivation and behaviours conducive to successful weight management. What is already known on this subject? Autonomy support is related to basic need satisfaction and autonomous motivation in the context of weight management. In turn, these variables are related to adaptive outcomes for weight management. What does this study add? Measurement of perceived controlling behaviours by important others. Measurement of perceived need thwarting. Structural model on how important others affect

years. Oceanic inputs of nitrate and ammonium were an important source of inorganic nitrogen to the estuary in both years. In both years, the total seasonal inputs of ammonium to the estuary in flood tides were much larger than the inputs from watershed runoff or direct precipitation. In 2011, the total seasonal input of nitrate from flood tides to the estuary was more than twice as large the inputs from watershed runoff and precipitation, but in 2012, the inputs from flood tides were only marginally larger than the inputs from watershed runoff and precipitation. Turbidity was measured intermittently in 2012, and the pattern that emerged from the measurements indicated that the estuary was a source of particulate matter to the ocean rather than the ocean being a source to the estuary. From the nutrient budgets determined for the estuary it is evident that oceanic sources of nitrate and ammonium are an important part of the supply of nutrients that are contributing to the growth of macroalgae in the estuary. The relative importance of these oceanic nutrients compared with sources within the watershed typically increases as the summer progresses and runoff decreases. It is likely that rising sea levels, estimated by the National Oceanic and Atmospheric Administration to be 11 centimeters from 1950 through 2006 in nearby Bar Harbor, have resulted in an increase in oceanic inputs (tidal volume and nutrients derived from oceanic sources).

Vegans have a lower incidence of insulin resistance (IR)-associated diseases and a higher insulin sensitivity (IS) compared with omnivores. The aim of this study was to examine whether the higher IS in vegans relates to markers of mitochondrial biogenesis and to intramyocellular lipid (IMCL) content. Eleven vegans and 10 matched (race, age, sex, body mass index, physical activity and energy intake) omnivorous controls were enrolled in a case-control study. Anthropometry, bioimpedance (BIA), ultrasound measurement of visceral and subcutaneous fat layer, parameters of glucose and lipid homeostasis, hyperinsulinemic euglycemic clamp and muscle biopsies were performed. Citrate synthase (CS) activity, mitochondrial DNA (mtDNA) and IMCL content were assessed in skeletal muscle samples. Both groups were comparable in anthropometric and BIA parameters, physical activity and protein-energy intake. Vegans had significantly higher glucose disposal (M-value, vegans 8.11±1.51 vs controls 6.31±1.57 mg/kg/min, 95% confidence interval: 0.402 to 3.212, P=0.014), slightly lower IMCL content (vegans 13.91 (7.8 to 44.0) vs controls 17.36 (12.4 to 78.5) mg/g of muscle, 95% confidence interval: -7.594 to 24.550, P=0.193) and slightly higher relative muscle mtDNA amount (vegans 1.36±0.31 vs controls 1.13±0.36, 95% confidence interval:-0.078 to 0.537, P=0.135). No significant differences were found in CS activity (vegans 18.43±5.05 vs controls 18.16±5.41 μmol/g/min, 95% confidence interval: -4.503 to 5.050, P=0.906). Vegans have a higher IS, but comparable mitochondrial density and IMCL content with omnivores. This suggests that a decrease in whole-body glucose disposal may precede muscle lipid accumulation and mitochondrial dysfunction in IR development.

The Role of China in the UK Relative Imports from Three Selected Trading Regions: The Case of Textile Raw Material Industry

Science.gov (United States)

Xu, Junqian

2017-01-01

The UK textile industry was very prosperous in the past but in the 1970s Britain started to import textile materials from abroad. Since 1990, half of its textile materials have been imported from the EEA (European Economic Area), ASEAN (Association of Southeast Asian Nations) and North America countries. Meanwhile, UK imports from China have increased dramatically. Through comparisons, this paper calculates the trade competitiveness index and relative competitive advantages of regions and investigates the impact of Chinese textiles on UK imports from three key free trade regions across the textile sectors in the period 1990–2016 on the basis of United Nation Comtrade Rev. 3. We find that China’s textile prices, product techniques, political trade barriers and even tax system have made a varied impact on the UK’s imports across related sectors in the context of green trade and the strengthening of barriers, which helps us recognize China’s competitiveness in international trading and also provides advice on China’s sustainable development of textile exports.

Relative Importance of Chemoautotrophy for Primary Production in a Light Exposed Marine Shallow Hydrothermal System

Directory of Open Access Journals (Sweden)

Gonzalo V. Gomez-Saez

2017-04-01

Full Text Available The unique geochemistry of marine shallow-water hydrothermal systems promotes the establishment of diverse microbial communities with a range of metabolic pathways. In contrast to deep-sea vents, shallow-water vents not only support chemosynthesis, but also phototrophic primary production due to the availability of light. However, comprehensive studies targeting the predominant biogeochemical processes are rare, and consequently a holistic understanding of the functioning of these ecosystems is currently lacking. To this end, we combined stable isotope probing of lipid biomarkers with an analysis of the bacterial communities to investigate if chemoautotrophy, in parallel to photoautotrophy, plays an important role in autotrophic carbon fixation and to identify the key players. The study was carried out at a marine shallow-water hydrothermal system located at 5 m water depth off Dominica Island (Lesser Antilles, characterized by up to 55°C warm hydrothermal fluids that contain high amounts of dissolved Fe2+. Analysis of the bacterial diversity revealed Anaerolineae of the Chloroflexi as the most abundant bacterial class. Furthermore, the presence of key players involved in iron cycling generally known from deep-sea hydrothermal vents (e.g., Zetaproteobacteria and Geothermobacter, supported the importance of iron-driven redox processes in this hydrothermal system. Uptake of 13C-bicarbonate into bacterial fatty acids under light and dark conditions revealed active photo- and chemoautotrophic communities, with chemoautotrophy accounting for up to 65% of the observed autotrophic carbon fixation. Relatively increased 13C-incorporation in the dark allowed the classification of aiC15:0, C15:0, and iC16:0 as potential lipid biomarkers for bacterial chemoautotrophy in this ecosystem. Highest total 13C-incorporation into fatty acids took place at the sediment surface, but chemosynthesis was found to be active down to 8 cm sediment depth. In conclusion

ldentification of Needs for Higher Education of Adults

Directory of Open Access Journals (Sweden)

Darka Podmenik

1997-12-01

Full Text Available The paper, which is a summary of a longer study, presents the most important conceptual and methodological approaches to the identification of the needs for adult education. The conceptual approaches are related to the theoretical treatment of the needs, such as the behaviourist and development-humanist theory of the needs applied in psychology, the class-strata needs theory developed by sociologists, and an understanding of the needs characteristic of marketing. A special chapter considers the applicability of individual conceptual approaches to identification of the needs for adult education within higher education. A consequence of multiplicity of conceptual approaches to the identification of the needs is a methodological pluralism which becomes evident in empirical work. In the subsequent chapter the author outlines the already established methods for identification of the needs and "a case study" carried out by the researchers of the former Centre for the Development of the University. In the conclusion the author makes a few proposals for improvement of the identification of the needs for adult education in the sphere of Slovenian higher education.

Notes on strings and higher spins

2013-01-01

This review is devoted to the intriguing and still largely unexplored links between string theory and higher spins, the types of excitations that lie behind their most cherished properties. A closer look at higher spin fields provides some further clues that string theory describes a broken phase of a higher spin gauge theory. Conversely, string amplitudes contain a wealth of information on higher spin interactions that can clarify long-standing issues related to their infrared behavior. This article is part of a special issue of Journal of Physics A: Mathematical and Theoretical devoted to ‘Higher spin theories and holography’. (review)

2018-02-01

Full Text Available The higher education experience is a challenge for first-year students. One of the challenges facing a generation of youth is attaining professional skills, academic experience and occupational training. In order to have a clear picture of the challenges involved in first-year experiences it is important to examine elements impacting first-year students' adjustment to university and in particular on the dual faculty role. This opinion paper posits that higher education faculties play an important role in the successful adjustment of first-year students, not only in facilitating their learning, but in impacting students' well-being and their growth as better citizens. The findings from this paper were drawn from various studies looking at the importance of first-year faculties in higher education, which involved extensive literature reviews and reported interviews with university stakeholders. The paper offers higher education leadership insights into the complex factors at play and the dual role faculties hold.

A Model for the Regionalization of Higher Education: The Role and Contribution of Tuning

Directory of Open Access Journals (Sweden)

Jane Knight

2014-04-01

Full Text Available A notable evolution in the internationalization of higher education in the last decade has been the increasing emphasis on regional level collaboration and reform initiatives. The purpose of this paper is to examine the process of regionalization through the lens of a conceptual model and to demonstrate how different Tuning initiatives serve as useful instruments in the application of the model, and the ultimate realization of higher education regionalization. The evolving nature and meaning of region and regionalization are explored in the first section of the paper. This leads to an analysis and conceptual mapping of the many terms used to describe the phenomenon. The proposed model is based on three distinct but complementary approaches; Functional, Organizational and Political Approaches (FOPA. The three approaches are inter-related. The model is generic in concept and purpose so that it can apply to the evolving process of higher education regionalization in different parts of the world. The article examines how the initiatives and implications of the Tuning process are directly related to the model and consequently make important contributions to the regionalization of higher education in all regions of the world.

Investigation of nuclide importance to functional requirements related to transport and long-term storage of LWR spent fuel

International Nuclear Information System (INIS)

Broadhead, B.L.; DeHart, M.D.; Ryman, J.C.; Tang, J.S.; Parks, C.V.

1995-06-01

This study investigates the relative importances of the various actinide, fission-product, and light-element isotopes associated with LWR spent fuel with respect to five analysis areas: criticality safety (absorption fractions), shielding (dose rate fractions), curies (fractional curies levels), decay heat (fraction of total watts), and radiological toxicity (fraction of potential committed effective dose equivalent). These rankings are presented for up to six different burnup/enrichment scenarios and at decay times from 2 to 100,000 years. Ranking plots for each of these analysis areas are given in an Appendix for completeness, as well as summary tables in the main body of the report. Summary rankings are presented in terms of high (greater than 10% contribution to the total), medium (between 1% and 10% contribution), and low (less than 1% contribution) for both short- and long-term cooling. When compared with the expected measurement accuracies, these rankings show that most of the important isotopes can be characterized sufficiently for the purpose of radionuclide generation/depletion code validation in each of the analysis areas. Because the main focus of this work is on the relative importances of isotopes associated with L at sign spent fuel, some conclusions may not be applicable to similar areas such as high-level waste (HLW) and nonfuel-bearing components (NFBC)

Radiosensitivity of higher plants

Feng Zhijie

1992-11-01

The general views on radiosensitivity of higher plants have been introduced from published references. The radiosensitivity varies with species, varieties and organs or tissues. The main factors of determining the radiosensitivity in different species are nucleus volume, chromosome volume, DNA content and endogenous compounds. The self-repair ability of DNA damage and chemical group of biological molecules, such as -SH thiohydroxy of proteins, are main factors to determine the radiosensitivity in different varieties. The moisture, oxygen, temperature radiosensitizer and protector are important external factors for radiosensitivity. Both the multiple target model and Chadwick-Leenhouts model are ideal mathematical models for describing the radiosensitivity of higher plants and the latter has more clear significance in biology

Leptospirosis belongs to the spectrum of travel-related infections. We retrospectively studied all the consecutive cases of travel-related leptospirosis seen in our department between January 2008 and September 2011. Patients were included with a clinical picture compatible with the disease within 21 days after return, the presence of a thermoresistant antigen or IgM antibodies, Elisa ≥ 1 /400, and a positive microagglutination test (MAT) ≥ 1/100. Fifteen leptospirosis cases were evaluated. Exposure occurred in Asia (47%), Africa (20%), the Caribbean (20%), and Indian Ocean (13%). Fourteen patients were infected during water-related activities. On admission the most frequent symptoms were fever (100%), headache (80%), and digestive disorders (67%). Relevant laboratory findings included impaired liver function tests (100%), lymphocytopenia (80%), thrombocytopenia (67%), and elevated C-reactive protein (CRP) (67%). Our cases were confirmed by MAT that found antibodies against nine different serovars. Seven patients were cured with amoxicillin, four with doxycycline, two with ceftriaxone, one with ceftriaxone, doxycycline, and spiramycin, whereas one recovered spontaneously (retrospective diagnosis). Eight patients were hospitalized. All patients recovered. Our cases involved nine different serovars. They were related to travel in Asia, Africa, and the Caribbean. Bathing or other fresh-water leisure activities (canoeing, kayaking, rafting) are the most likely at-risk exposure. Any traveler with fever and at-risk exposure should be investigated for leptospirosis. © 2013 International Society of Travel Medicine.

2018-01-01

Full Text Available Introduction. Student population is the most important social resource of development of post-industrial information society. Therefore, those students will take places of leading experts and will define the level of social and economic wellbeing of the country and its competitiveness in the world in the near future. In this regard, it is important to find out the potential of the student's environment in order to convert it without any loss into social and cultural capital of the state. First of all, this potential is made up by education, qualification and profession and students’ valuable relation to their occupation. Thereby, such valuable relation depends on a degree of a future specialist’ personal maturity, a degree of his/her responsibility for the activity, and readiness for professional selfimprovement.The aims of the present publication are: to analyse the processes of professional self-determination among students; to reveal the tendencies of students’ professional self-determination.Methodology and research methods. The methodological basis of the research involves modern scientific theories formulated within branches of Sociology – Sociology of Education and Sociology of Youth. Representative quota-cluster selective questionnaire survey was used as the main method; that was carried out in seven steps in 1995–2016. The total amount of selection involved 9133 students studying in higher education institutions of Sverdlovsk region – one of the largest administrative territories of Russia.Results and scientific novelty. The results of a unique long-term monitoring are generalized and interpreted. In the course of the monitoring, the dynamics of professional self-determination of student youth was traced by means of such key indicators as follows: motives of the choice of the sphere of employment and educational institution; personal importance of future profession for students; professional plans of students after

The importance of Justinian's codification work in the field of marital relations

Full Text Available This paper tries to describe theoretically some of the numerous questions regarding the marriage in Justinian's time (525-565. By finishing the work of his predecessors (Gregorian, Hermogenian, Theodosius, Justinian codified the whole of Roman law. Of course, when we speak about Justinian, we also have in mind Tribonian and other members of his team. He introduced many innovations in family, i.e. marital relations: cognate kinship (blood kinship replaced agnate kinship; the head of a family had no more 'right of life or death' (ius vitae ac necis over the family members; marriage was reformed and a lot of restrictions were abolished as well as many pagan rituals involved in the act of getting married, and the divorce was no more 'duty but right'. Under the influence of Christianity that was spread in the first century among slaves and the poor and the moral purity that had been preached by Christianity - Justinian continued the policy of his predecessors (August, Constantine, Theodosius towards strengthening marriage and family. Even in the period of spreading Christianity across the Roman Empire, ancient Roman religious rituals were becoming less common due to decreased importance of religion and ethics. Roman legislation in that period did not insist on formalities in the process of getting married; it insisted on a mutual agreement of a bride and bridegroom and after that the marriage was contracted as a 'legal union' - consensus facit nuptias - as the Romans said. In the Justinian time, although the marriage was under a great influence of Christianity, it required no church blessing for a contracted marriage. That condition will be introduced by Leo the Wise in the 9th century for the Eastern Roman Empire. According to Justinian, a marriage is 'the relationship of a husband and wife that contains permanent life community'. The procedure and the attached activities that accompany the act of getting married (engagement, dowry, premarital gift

2007-08-01

We focus in this work to renew the interest in higher conformal spins symmetries and their relations to quantum field theories and integrable models. We consider the extension of the conformal Frappat et al. symmetries containing the Virasoro and the Antoniadis et al. algebras as particular cases describing geometrically special diffeomorphisms of the two dimensional torus T 2 . We show in a consistent way, and explicitly, how one can extract these generalized symmetries from the Gelfand-Dickey algebra. The link with Liouville and Toda conformal field theories is established and various important properties are discussed. (author)

The aim of this study was to explore and understand the complexity of ageing in relation to factors of importance for extending working life. Discourse analysis of documents was used in an integrative review including 128 articles. Four different conceptualisation of ageing are shown to affect older workers' ability to extend their working life: (a) biological ageing people's health in relation to their physical and mental work environment, their pace of work and recuperation needs; (b) chronological ageing statutory retirement age and policies and economic incentives devised for older workers by society, unions and organisations/enterprises; (c) social ageing inclusion in different social groups, the attitude of managers, organisations and family members, the leisure activities and surrounding environment; and (d) mental/cognitive ageing self-crediting, motivating and meaningful activities, competence and skills in working life.

Higher spin gauge theories

CERN Document Server

Henneaux, Marc; Vasiliev, Mikhail A

2017-01-01

Symmetries play a fundamental role in physics. Non-Abelian gauge symmetries are the symmetries behind theories for massless spin-1 particles, while the reparametrization symmetry is behind Einstein's gravity theory for massless spin-2 particles. In supersymmetric theories these particles can be connected also to massless fermionic particles. Does Nature stop at spin-2 or can there also be massless higher spin theories. In the past strong indications have been given that such theories do not exist. However, in recent times ways to evade those constraints have been found and higher spin gauge theories have been constructed. With the advent of the AdS/CFT duality correspondence even stronger indications have been given that higher spin gauge theories play an important role in fundamental physics. All these issues were discussed at an international workshop in Singapore in November 2015 where the leading scientists in the field participated. This volume presents an up-to-date, detailed overview of the theories i...

The development process and its relation to oil revenues and dependence on imported labor market in Saudi Arabia

International Nuclear Information System (INIS)

Almtairi, N.M.

1991-01-01

This study describes and analyzes the process of development in Saudi Arabia in relation to oil revenues and Saudi Arabian dependence on imported foreign labor. Modern development and societal change in Saudi Arabia began with the commercial exploitation of oil in 1939, therefore Saudi economy must be viewed from a dual perspective: a highly capital-intensive oil sector and a labor-intensive non-oil sector. In one generation the Kingdom created an infrastructure suitable to a rapid transformation from Bedouin tribes to a modern state, which became a leading regional power and now occupies an important place in international society. Important advances were made in social services, health services and education at all levels. Large-scale importation of foreign labor workers during the 1970s and early 1980s was necessary for the Development Plans. By the 1990s the major infrastructure was completed and only the maintenance work and minor projects remained for foreign labor sources

2016-01-01

. We assessed HRQOL by the children's self-report and parent proxy report module of the PedsQL™ 4.0 Generic Core Scales. We found that non-overweight children scored HRQOL slightly higher than overweight ones but significantly higher than did obese children. The same pattern was seen for the mothers......The aim was to study how, and to what degree, health-related quality of life (HRQOL), as assessed by children and their mothers, was related to overweight and obesity among children aged seven to nine years. Mother-child pairs of 149 non-overweight, 95 overweight and 16 obese children participated......, there is a need for information of mothers/parents about the impact of overweight and obesity on children's HRQOL. Such intervention by health professionals may among other interventions help to prevent and reduce overweight and obesity among children and thus help to increase the children's HRQOL throughout...

Do higher salaries lower physician migration?

Science.gov (United States)

Okeke, Edward N

2014-08-01

It is believed that low wages are an important reason why doctors and nurses in developing countries migrate, and this has led to a call for higher wages for health professionals in developing countries. In this paper, we provide some of the first estimates of the impact of raising health workers' salaries on migration. Using aggregate panel data on the stock of foreign doctors in 16 Organization for Economic Cooperation and Development countries, we explore the effect of a wage increase programme in Ghana on physician migration. We find evidence that 6 years after the implementation of this programme, the foreign stock of Ghanaian doctors abroad had fallen by approximately 10% relative to the estimated counterfactual. This result should be interpreted with caution, however, given the sensitivity of the results to changes in model specification.

Permutation importance: a corrected feature importance measure.

Altmann, André; Toloşi, Laura; Sander, Oliver; Lengauer, Thomas

2010-05-15

In life sciences, interpretability of machine learning models is as important as their prediction accuracy. Linear models are probably the most frequently used methods for assessing feature relevance, despite their relative inflexibility. However, in the past years effective estimators of feature relevance have been derived for highly complex or non-parametric models such as support vector machines and RandomForest (RF) models. Recently, it has been observed that RF models are biased in such a way that categorical variables with a large number of categories are preferred. In this work, we introduce a heuristic for normalizing feature importance measures that can correct the feature importance bias. The method is based on repeated permutations of the outcome vector for estimating the distribution of measured importance for each variable in a non-informative setting. The P-value of the observed importance provides a corrected measure of feature importance. We apply our method to simulated data and demonstrate that (i) non-informative predictors do not receive significant P-values, (ii) informative variables can successfully be recovered among non-informative variables and (iii) P-values computed with permutation importance (PIMP) are very helpful for deciding the significance of variables, and therefore improve model interpretability. Furthermore, PIMP was used to correct RF-based importance measures for two real-world case studies. We propose an improved RF model that uses the significant variables with respect to the PIMP measure and show that its prediction accuracy is superior to that of other existing models. R code for the method presented in this article is available at http://www.mpi-inf.mpg.de/ approximately altmann/download/PIMP.R CONTACT: altmann@mpi-inf.mpg.de, laura.tolosi@mpi-inf.mpg.de Supplementary data are available at Bioinformatics online.

The second higher education and additional education as factors of development of commercialization in Ukrainian higher education

Directory of Open Access Journals (Sweden)

M. V. Strigul

2017-07-01

Full Text Available The attention in the article has been drawn to the nature and characteristics of commercialization in the higher education system of Ukraine. It has been noted that commercialization in the consumer society is a social process of transformation of knowledge into a product or service. It provides the growing influence of market relations on the goals and objectives of higher education, promotes the growing importance of knowledge as a source for economic development and focuses on the concept of rooting and academic capitalism and the creation of market-oriented and entrepreneurial universities, which provide dynamic development of economy based on knowledge. Defining the essence of the Ukrainian forms of commercialization, there is a significant role of further and second higher education (that is, the presence of a variety of educational forms, which allows the University receiving the profit in the monetary form. The model of commercialization, which is implemented in Ukrainian higher education, differs from the American and Western European ones, as it is focused on financial returns, not on the economization of intellectual profit. Secondly, a peculiar type of consumer behavior, consumerism, which provides growth of profitability of higher education institutions by a variety of additional services (training, additional courses, further education, developing classes, retaking tests, etc.. The factors of development and dynamics of the Ukrainian forms of commercialization, as well as recommendations for avoiding the negative consequences of the economization and commercialization in higher education structure of modern Ukraine have been considered in the article. It has been noted that the University lost its original purpose and became a huge supermarket, which offers various kinds of knowledge. Rational action considers in the desire to buy the most qualitative product – a diploma from a prestigious University. Nowadays, the higher

The relation between the bosonic higher spin W{sub ∞}[λ] algebra, the affine Yangian of gl{sub 1}, and the SH{sup c} algebra is established in detail. For generic λ we find explicit expressions for the low-lying W{sub ∞}[λ] modes in terms of the affine Yangian generators, and deduce from this the precise identification between λ and the parameters of the affine Yangian. Furthermore, for the free field cases corresponding to λ=0 and λ=1 we give closed-form expressions for the affine Yangian generators in terms of the free fields. Interestingly, the relation between the W{sub ∞} modes and those of the affine Yangian is a non-local one, in general. We also establish the explicit dictionary between the affine Yangian and the SH{sup c} generators. Given that Yangian algebras are the hallmark of integrability, these identifications should pave the way towards uncovering the relation between the integrable and the higher spin symmetries.

2015-03-22

Insect pollinators provide a crucial ecosystem service, but are under threat. Urban areas could be important for pollinators, though their value relative to other habitats is poorly known. We compared pollinator communities using quantified flower-visitation networks in 36 sites (each 1 km(2)) in three landscapes: urban, farmland and nature reserves. Overall, flower-visitor abundance and species richness did not differ significantly between the three landscape types. Bee abundance did not differ between landscapes, but bee species richness was higher in urban areas than farmland. Hoverfly abundance was higher in farmland and nature reserves than urban sites, but species richness did not differ significantly. While urban pollinator assemblages were more homogeneous across space than those in farmland or nature reserves, there was no significant difference in the numbers of rarer species between the three landscapes. Network-level specialization was higher in farmland than urban sites. Relative to other habitats, urban visitors foraged from a greater number of plant species (higher generality) but also visited a lower proportion of available plant species (higher specialization), both possibly driven by higher urban plant richness. Urban areas are growing, and improving their value for pollinators should be part of any national strategy to conserve and restore pollinators.

Full Text Available Abstract Background To evaluate the prevalence of more virulent H. pylori genotypes in relatives of gastric cancer patients and in patients without family histories of gastric cancer. Methods We evaluated prospectively the prevalence of the infection by more virulent H. pylori strains in 60 relatives of gastric cancer patients comparing the results with those obtained from 49 patients without family histories of gastric cancer. H. pylori status was determined by the urease test, histology and presence of H. pylori ureA. The cytotoxin associated gene (cagA, the cagA-EPIYA and vacuolating cytotoxin gene (vacA were typed by PCR and the cagA EPIYA typing was confirmed by sequencing. Results The gastric cancer relatives were significant and independently more frequently colonized by H. pylori strains with higher numbers of CagA-EPIYA-C segments (OR = 4.23, 95%CI = 1.53–11.69 and with the most virulent s1m1 vacA genotype (OR = 2.80, 95%CI = 1.04–7.51. Higher numbers of EPIYA-C segments were associated with increased gastric corpus inflammation, foveolar hyperplasia and atrophy. Infection by s1m1 vacA genotype was associated with increased antral and corpus gastritis. Conclusions We demonstrated that relatives of gastric cancer patients are more frequently colonized by the most virulent H. pylori cagA and vacA genotypes, which may contribute to increase the risk of gastric cancer.

Relative importance of precipitation frequency and intensity in inter-annual variation of precipitation in Singapore during 1980-2013

Science.gov (United States)

Li, Xin; Babovic, Vladan

2017-04-01

Observed studies on inter-annual variation of precipitation provide insight into the response of precipitation to anthropogenic climate change and natural climate variability. Inter-annual variation of precipitation results from the concurrent variations of precipitation frequency and intensity, understanding of the relative importance of frequency and intensity in the variability of precipitation can help fathom its changing properties. Investigation of the long-term changes of precipitation schemes has been extensively carried out in many regions across the world, however, detailed studies of the relative importance of precipitation frequency and intensity in inter-annual variation of precipitation are still limited, especially in the tropics. Therefore, this study presents a comprehensive framework to investigate the inter-annual variation of precipitation and the dominance of precipitation frequency and intensity in a tropical urban city-state, Singapore, based on long-term (1980-2013) daily precipitation series from 22 rain gauges. First, an iterative Mann-Kendall trend test method is applied to detect long-term trends in precipitation total, frequency and intensity at both annual and seasonal time scales. Then, the relative importance of precipitation frequency and intensity in inducing the inter-annual variation of wet-day precipitation total is analyzed using a dominance analysis method based on linear regression. The results show statistically significant upward trends in wet-day precipitation total, frequency and intensity at annual time scale, however, these trends are not evident during the monsoon seasons. The inter-annual variation of wet-day precipitation is mainly dominated by precipitation intensity for most of the stations at annual time scale and during the Northeast monsoon season. However, during the Southwest monsoon season, the inter-annual variation of wet-day precipitation is mainly dominated by precipitation frequency. These results have

Full Text Available Tourism is an important determinant for a region’s economic growth—the higher income from tourism, the higher its gross regional domestic product. To be successful in exposing potential tourism sites, a region does not only depend on the beauty of the nature but also how to access the sites, on-site accommodation and the mutual relationship between local government and local community.The fact is many regions have difficulties in developing mutual relationship between local government and local community. It means what most important is how the tourism industry is being managed. One most important aspect of managing the tourism industry is the cooperation and communication between the local community and the government. This article aims to discuss how public relations and the local community work to stimulate tourism growth in a synergy. Using descriptive qualitative method, this article recommends a model of communication strategy—in which the local community serves mainly as the tourism’s public relation agents, and also serves as a reference method in evaluating a local government’s communication strategies in regional tourism industry.

Disentangling the relative importance of changes in climate and land-use intensity in driving recent bird population trends.

Directory of Open Access Journals (Sweden)

Sarah M Eglington

Full Text Available Threats to biodiversity resulting from habitat destruction and deterioration have been documented for many species, whilst climate change is regarded as increasingly impacting upon species' distribution and abundance. However, few studies have disentangled the relative importance of these two drivers in causing recent population declines. We quantify the relative importance of both processes by modelling annual variation in population growth of 18 farmland bird species in the UK as a function of measures of land-use intensity and weather. Modelled together, both had similar explanatory power in accounting for annual fluctuations in population growth. When these models were used to retrodict population trends for each species as a function of annual variation in land-use intensity and weather combined, and separately, retrodictions incorporating land-use intensity were more closely linked to observed population trends than retrodictions based only on weather, and closely matched the UK farmland bird index from 1970 onwards. Despite more stable land-use intensity in recent years, climate change (inferred from weather trends has not overtaken land-use intensity as the dominant driver of bird populations.

2015-01-01

We analyzed food market basket samples obtained in Sweden from 1999, 2005, and 2010 for perfluoroalkyl acids (PFAAs) and a range of precursor compounds. Perfluorooctane sulfonic acid (PFOS) precursors were detected in all food year pools with the highest concentrations in 1999. Six polyfluoroalkyl phosphate diesters (diPAPs, 4:2/6:2, 6:2/6:2, 6:2/8:2, 8:2/8:2, 6:2/10:2, and 10:2/10:2) were detected in the year pools with the highest ∑diPAP concentrations in 1999 and 2005. All precursors were predominantly found in meat, fish, and/or eggs based on analysis of individual food groups from 1999. Based on year pools, PFOS precursors contributed between 4 and 1% as an indirect source to total dietary PFOS intakes between 1999 and 2010. Perfluorohexanoic acid (PFHxA) exposure originated entirely from diPAPs, whereas for perfluorooctanoic acid (PFOA) and perfluorodecanoic acid (PFDA), diPAPs contributed between 1 and 19% to total exposure. The lowest precursor contributions were generally seen in food samples from 2010. - Highlights: • Three PFOS precursors and six diPAPs were detected in food pools. • Precursor concentrations were highest in 1999 and 2005 food pools, and lowest in 2010. • The relative importance of precursors to total PFOS dietary intake was <4%. • The relative importance of diPAPs as an indirect dietary source of PFCAs was chain length dependent. - The relative contribution of precursors to PFOS dietary intakes is small, whereas the contribution of diPAPs to PFCA dietary intakes varies with the PFCA chain length

Nowadays most of the university students are required to undergo internship as a requirement before graduation. Internship is very important for students to practice what they have learned in the classroom. During internship students are exposed to the actual situation of how to deal with customers and suppliers which can provide added value to the students. In the choice of company for internship, students also consider a number of things such as internship allowances, work environment, interesting work, stable work shift and other fridge benefits. Study on the importance and satisfaction of students is important to improve the internship program. Importance means how students feel important to the attributes and satisfaction means how students feel after undergoing internship. The aim of this study is to investigate the gaps between students' important and satisfaction on the internship programme and to identify the internship experience factors that need to be improved. Gap analysis has been used to show the difference between how important attributes are to the studentss and how satisfied they are with those attributes. Result shows that the attributes that has high importance and satisfaction to the students are good peer relationship, broad work experience, competitive fringe benefits, interesting work, work environment, sufficient supervisory support, appreciation and praise from manager, feeling of being a team members, able to identify self-strength and able to develop technical skills. In contrast, three attributes are considered importance but low satisfaction. These attributes are internship allowances, opportunity for self-development, and able to develop interests through practice.

Herbert, Cornelia; Kübler, Andrea

2011-01-01

The present study investigated event-related brain potentials elicited by true and false negated statements to evaluate if discrimination of the truth value of negated information relies on conscious processing and requires higher-order cognitive processing in healthy subjects across different levels of stimulus complexity. The stimulus material consisted of true and false negated sentences (sentence level) and prime-target expressions (word level). Stimuli were presented acoustically and no overt behavioral response of the participants was required. Event-related brain potentials to target words preceded by true and false negated expressions were analyzed both within group and at the single subject level. Across the different processing conditions (word pairs and sentences), target words elicited a frontal negativity and a late positivity in the time window from 600-1000 msec post target word onset. Amplitudes of both brain potentials varied as a function of the truth value of the negated expressions. Results were confirmed at the single-subject level. In sum, our results support recent suggestions according to which evaluation of the truth value of a negated expression is a time- and cognitively demanding process that cannot be solved automatically, and thus requires conscious processing. Our paradigm provides insight into higher-order processing related to language comprehension and reasoning in healthy subjects. Future studies are needed to evaluate if our paradigm also proves sensitive for the detection of consciousness in non-responsive patients.

Taking the Perfect Selfie: Investigating the Impact of Perspective on the Perception of Higher Cognitive Variables

Full Text Available Taking selfies is now becoming a standard human habit. However, as a social phenomenon, research is still in the fledgling stage and the scientific framework is sparse. Selfies allow us to share social information with others in a compact format. Furthermore, we are able to control important photographic and compositional aspects, such as perspective, which have a strong impact on the assessment of a face (e.g., demonstrated by the height-weight illusion, effects of gaze direction, faceism-index. In Study 1, we focused on the impact of perspective (left/right hemiface, above/below vs. frontal presentation on higher cognitive variables and let 172 participants rate the perceived attractiveness, helpfulness, sympathy, dominance, distinctiveness, and intelligence, plus important information on health issues (e.g., body weight, on the basis of 14 3D faces. We could show that lateral snapshots yielded higher ratings for attractiveness compared to the classical frontal view. However, this effect was more pronounced for left hemifaces and especially female faces. Compared to the frontal condition, 30° right hemifaces were rated as more helpful, but only for female faces while faces viewed from above were perceived as significant less helpful. Direct comparison between left vs. right hemifaces revealed no effect. Relating to sympathy, we only found a significant effect for 30° right male hemifaces, but only in comparison to the frontal condition. Furthermore, female 30° right hemifaces were perceived as more intelligent. Relating to body weight, we replicated the so-called “height-weight illusion.” Other variables remained unaffected. In Study 2, we investigated the impact of a typical selfie-style condition by presenting the respective faces from a lateral (left/right and tilted (lower/higher vantage point. Most importantly, depending on what persons wish to express with a selfie, a systematic change of perspective can strongly optimize their

The relative importance among anthropogenic forcings of land use/land cover change in affecting temperature extremes

Science.gov (United States)

Chen, Liang; Dirmeyer, Paul A.

2018-05-01

Land use/land cover change (LULCC) exerts significant influence on regional climate extremes, but its relative importance compared with other anthropogenic climate forcings has not been thoroughly investigated. This study compares land use forcing with other forcing agents in explaining the simulated historical temperature extreme changes since preindustrial times in the CESM-Last Millennium Ensemble (LME) project. CESM-LME suggests that the land use forcing has caused an overall cooling in both warm and cold extremes, and has significantly decreased diurnal temperature range (DTR). Due to the competing effects of the GHG and aerosol forcings, the spatial pattern of changes in 1850-2005 climatology of temperature extremes in CESM-LME can be largely explained by the land use forcing, especially for hot extremes and DTR. The dominance of land use forcing is particularly evident over Europe, eastern China, and the central and eastern US. Temporally, the land-use cooling is relatively stable throughout the historical period, while the warming of temperature extremes is mainly influenced by the enhanced GHG forcing, which has gradually dampened the local dominance of the land use effects. Results from the suite of CMIP5 experiments partially agree with the local dominance of the land use forcing in CESM-LME, but inter-model discrepancies exist in the distribution and sign of the LULCC-induced temperature changes. Our results underline the overall importance of LULCC in historical temperature extreme changes, implying land use forcing should be highlighted in future climate projections.

Remote Sensing of plant functional types: Relative importance of biochemical and structural plant traits

Science.gov (United States)

Kattenborn, Teja; Schmidtlein, Sebastian

2017-04-01

Monitoring ecosystems is a key priority in order to understand vegetation patterns, underlying resource cycles and changes their off. Driven by biotic and abiotic factors, plant species within an ecosystem are likely to share similar structural, physiological or phenological traits and can therefore be grouped into plant functional types (PFT). It can be assumed that plants which share similar traits also share similar optical characteristics. Therefore optical remote sensing was identified as a valuable tool for differentiating PFT. Although several authors list structural and biochemical plant traits which are important for differentiating PFT using hyperspectral remote sensing, there is no quantitative or qualitative information on the relative importance of these traits. Thus, little is known about the explicit role of plant traits for an optical discrimination of PFT. One of the main reasons for this is that various optical traits affect the same wavelength regions and it is therefore difficult to isolate the discriminative power of a single trait. A way to determine the effect of single plant traits on the optical reflectance of plant canopies is given by radiative transfer models. The most established radiative transfer model is PROSAIL, which incorporates biochemical and structural plant traits, such as pigment contents or leaf area index. In the present study 25 grassland species of different PFT were cultivated and traits relevant for PROSAIL were measured for the entire vegetation season of 2016. The information content of each trait for differentiating PFTs was determined by applying a Multi-response Permutation Procedure on the actual traits, as well as on simulated canopy spectra derived from PROSAIL. According to our results some traits, especially biochemical traits, show a weaker separability of PFT on a spectral level than compared to the actual trait measurements. Overall structural traits (leaf angle and leaf area index) are more important for

Quantifying The Relative Importance Of Phylogeny And Environmental Preferences As Drivers Of Gene Content In Prokaryotic Microorganisms

Full Text Available Two complementary forces shape microbial genomes: vertical inheritance of genes by phylogenetic descent, and acquisition of new genes related to adaptation to particular habitats and lifestyles. Quantification of the relative importance of each driving force proved difficult. We determined the contribution of each factor, and identified particular genes or biochemical/cellular processes linked to environmental preferences (i.e., propensity of a taxon to live in particular habitats. Three types of data were confronted: [i] complete genomes, which provide gene content of different taxa; [ii] phylogenetic information, via alignment of 16S rRNA sequences, which allowed determination of the distance between taxa, and [iii] distribution of species in environments via 16S rRNA sampling experiments, reflecting environmental preferences of different taxa. The combination of these three datasets made it possible to describe and quantify the relationships among them. We found that, although phylogenetic descent was responsible for shaping most genomes, a discernible part of the latter was correlated to environmental adaptations. Particular families of genes were identified as environmental markers, as supported by direct studies such as metagenomic sequencing. These genes are likely important for adaptation of bacteria to particular conditions or habitats, such as carbohydrate or glycan metabolism genes being linked to host-associated environments.

Rhizospheric fungi play major roles in both natural and agricultural ecosystems. However, little is known about the determinants of their diversity and biogeographic patterns. Here, we compared fungal communities in rhizosphere and bulk soils of wheat fields in the North China Plain. The rhizosphere had a lower fungal diversity (observed OTUs and Chao1) than bulk soil, and a distinct fungal community structure in rhizosphere compared with bulk soil. The relative importance of environmental factors and geographic distance for fungal distribution differed between rhizosphere and bulk soil. Environmental factors were the primary cause of variations in total fungal community and major fungal phyla in bulk soil. By contrast, fungal communities in soils loosely attached to roots were predictable from both environmental factors and influences of geographic distance. Communities in soils tightly attached to roots were mainly determined by geographic distance. Our results suggest that both contemporary environment processes (present-day abiotic and biotic environment characters) and historical processes (spatial isolation, dispersal limitation occurred in the past) dominate variations of fungal communities in wheat fields, but their relative importance of all these processes depends on the proximity of fungal community to the plant roots. © 2017 Society for Applied Microbiology and John Wiley & Sons Ltd.

The quality movement in higher education in the United States.

Buchanan, H S

Continuous quality improvement (CQI), often implemented as part of an integrated management system called total quality management (TQM), has been institutionalized within many manufacturing, military and service organizations in the USA as a response to declining market share, low productivity and customer complaints about poor quality. Signs and symptoms suggest that higher education has similar problems which are systematic and relate to the quality ot higher education, financing, facilities, curriculum and graduates. In the 1990S, the quality movement has begun to spread to the field of education as a means of diagnosing and treating the problems widely recognized as residing in US educational institutions, especially in colleges and universities. Many business leaders and authors believe that 'quality is the most important strategic issue facing top management in the 1990s'. This belief arises partly due to the fact that managers are beginning to understand the relationship between healthy, high quality organizations and healthy profits. This article traces the recent US quality movement from its roots in manufacturing and the military, its adoption by service institutions, and its more recent application by higher education institutions.

Full Text Available Recently, the higher education sector faces a series of changes, such as increased competition, globalization, limited funding. Limited funding does not reveal the full potential of the higher education, too little funding restricts research performance, diminishes the quality of higher education, worsen the conditions for learning and this has important implications for sustainable value creation. The article explores relationship between education, sustainability and financial indicators in order to evaluate the situation and advancement in the European countries, applied multi-criteria evaluation method MULTIMOORA. This method aims to prove that the more encourage investment in higher education and research, the more sustainable the state is and creates sustainable value. The results revealed that the more financially stronger and stable country is, the better position by assessing both the scientific and the sustainability indicators. Financially stable country can give higher investment in education, to promote the conduct of research, create conditions for the formation of high-quality R&D, to prepare highly qualified specialists.

Pridham, K F; Chang, A S; Hansen, M F

1987-08-01

Examination was made of the relationship of mothers' appraisal of the importance of and need for action around infant-related issues to maternal experience (parity and time since birth), use of help, and perceived problem-solving competence. Sixty-two mothers (38 primiparae and 24 multiparae) kept for 90 days post-birth a daily log of issues, rated for importance and for need for action, and of help used. Mothers also reported perceived problem-solving competence on an 11-item scale. Findings indicated tentativeness in ratings of importance and action. Ratings of importance were associated with action ratings, except for temperament issues. Action ratings for baby care and illness issues decreased significantly with time. Otherwise, maternal experience had no effect on ratings. More of the variance in perceived competence than use of help was explained by action and importance ratings.

Vision loss from age-related macular degeneration (AMD) has a profound effect on vision-related quality of life (VRQoL). The pupose of this study is to identify clinical factors associated with VRQoL using the Rasch- calibrated NEI VFQ-25 scales in bilateral advanced AMD patients. We retrospectively reviewed 47 patients (mean age 83.2 years) with bilateral advanced AMD. Clinical assessment included age, gender, type of AMD, high contrast visual acuity (VA), history of medical conditions, contrast sensitivity (CS), central visual field loss, report of Charles Bonnet Syndrome, current treatment for AMD and Rasch-calibrated NEI VFQ-25 visual function and socioemotional function scales. The NEI VFQ visual function scale includes items of general vision, peripheral vision, distance vision and near vision-related activity while the socioemotional function scale includes items of vision related-social functioning, role difficulties, dependency, and mental health. Multiple regression analysis (structural regression model) was performed using fixed item parameters obtained from the one-parameter item response theory model. Multivariate analysis showed that high contrast VA and CS were two factors influencing VRQoL visual function scale (β = -0.25, 95% CI-0.37 to -0.12, p<0.001 and β = 0.35, 95% CI 0.25 to 0.46, p<0.001) and socioemontional functioning scale (β = -0.2, 95% CI -0.37 to -0.03, p = 0.023, and β = 0.3, 95% CI 0.18 to 0.43, p = 0.001). Central visual field loss was not assoicated with either VRQoL visual or socioemontional functioning scale (β = -0.08, 95% CI-0.28 to 0.12,p = 0.44 and β = -0.09, 95% CI -0.03 to 0.16, p = 0.50, respectively). In patients with vision impairment secondary to bilateral advanced AMD, high contrast VA and CS are two important factors affecting VRQoL.

The selection of a future breeding dog is a complicated task, in which disease characteristics and different traits have to be combined and weighed against one another. Truncation selection, that is the exclusion of affected animals, may be very inefficient when selecting on a large number of traits, and may result in a reduction of the genetic diversity in a population or breed. Selection could be facilitated by the use of a selection index that combines multiple traits or breeding values into one score. This however requires a consideration of their relative value according to their economic weight, which is difficult to express in monetary units for health traits. The use of a choice experiment to derive non-market values might be a solution to this problem. This is a pilot study to assess the potential use of choice experiments to ascertain the public preference and relative importance attached to health- and conformation traits in the selection of a Cavalier King Charles spaniel. The focus was on two prevalent disorders, mitral valve disease and syringomyelia, and on several important conformation traits such as muzzle length and eye shape. Based on available prior information, a Bayesian D-optimal design approach was used to develop a choice experiment and the resulting choice sets. Every participant (breeder or owner) in the choice experiment was presented with a total of 17 choice sets, in which at most four traits could vary to reduce the cognitive burden. A total of 114 respondents participated in the choice experiment and results showed that respondents (breeders/owners) current attitudes were directed towards health (syringomyelia and mitral valve disease), followed by eye shape and level of inbreeding. This approach identifies the value breeders and owners attach to certain traits in the breeding objective. The resulting relative weights, represented as the logworths obtained from the choice experiment, could be an alternative to economic weights. They

Childhood Maltreatment and the Development of Relational and Physical Aggression: The Importance of a Gender-Informed Approach

This investigation examined the associations between maltreatment and aggression using a gender-informed approach. Peer ratings, peer nominations, and counselor reports of aggression were collected on 211 maltreated and 199 non-maltreated inner-city youth (mean age = 9.9 years) during a summer day camp. Maltreatment was associated with aggressive conduct; however, these effects were qualified by gender, maltreatment subtype, and the form of aggression under investigation. Findings revealed that maltreatment was associated with physical aggression for boys and relational aggression for girls. Physical abuse was associated with physically aggressive behaviors, but sexual abuse predicted relational aggression for girls only. Findings suggest that investigating the interaction between familial risk and gender is important in understanding aggressive behaviors of boys and girls. PMID:19037946

The importance of relations and rationality in ethnography

I claim that it is hard to understand the cooperation and also the distance that there is between the ethnographic field and the researcher when we are involved in ethnographic data collection. From the classical scholarly point of view, in an observation situation we can either be participatory...... place. I see nexus analysis as a methodology that can solve this dilemma. With nexus analysis, the researcher uses a fair amount of time to understand the people, their routines, work conditions, etc. in the field in question. Also, it is equally relevant for the researcher to get to know the concrete...... locations and places with their specific work practices. This is why the first and important step in nexus analysis is to “engage” in the practices that constitute the ethnographic field under analysis.

Mean velocity vs. mean propulsive velocity vs. peak velocity: which variable determines bench press relative load with higher reliability? J Strength Cond Res 32(5): 1273-1279, 2018-This study aimed to compare between 3 velocity variables (mean velocity [MV], mean propulsive velocity [MPV], and peak velocity [PV]): (a) the linearity of the load-velocity relationship, (b) the accuracy of general regression equations to predict relative load (%1RM), and (c) the between-session reliability of the velocity attained at each percentage of the 1-repetition maximum (%1RM). The full load-velocity relationship of 30 men was evaluated by means of linear regression models in the concentric-only and eccentric-concentric bench press throw (BPT) variants performed with a Smith machine. The 2 sessions of each BPT variant were performed within the same week separated by 48-72 hours. The main findings were as follows: (a) the MV showed the strongest linearity of the load-velocity relationship (median r = 0.989 for concentric-only BPT and 0.993 for eccentric-concentric BPT), followed by MPV (median r = 0.983 for concentric-only BPT and 0.980 for eccentric-concentric BPT), and finally PV (median r = 0.974 for concentric-only BPT and 0.969 for eccentric-concentric BPT); (b) the accuracy of the general regression equations to predict relative load (%1RM) from movement velocity was higher for MV (SEE = 3.80-4.76%1RM) than for MPV (SEE = 4.91-5.56%1RM) and PV (SEE = 5.36-5.77%1RM); and (c) the PV showed the lowest within-subjects coefficient of variation (3.50%-3.87%), followed by MV (4.05%-4.93%), and finally MPV (5.11%-6.03%). Taken together, these results suggest that the MV could be the most appropriate variable for monitoring the relative load (%1RM) in the BPT exercise performed in a Smith machine.

Higher-order fluctuation-dissipation relations in plasma physics: Binary Coulomb systems

Science.gov (United States)

Golden, Kenneth I.

2018-05-01

A recent approach that led to compact frequency domain formulations of the cubic and quartic fluctuation-dissipation theorems (FDTs) for the classical one-component plasma (OCP) [Golden and Heath, J. Stat. Phys. 162, 199 (2016), 10.1007/s10955-015-1395-6] is generalized to accommodate binary ionic mixtures. Paralleling the procedure followed for the OCP, the basic premise underlying the present approach is that a (k ,ω ) 4-vector rotational symmetry, known to be a pivotal feature in the frequency domain architectures of the linear and quadratic fluctuation-dissipation relations for a variety of Coulomb plasmas [Golden et al., J. Stat. Phys. 6, 87 (1972), 10.1007/BF01023681; J. Stat. Phys. 29, 281 (1982), 10.1007/BF01020787; Golden, Phys. Rev. E 59, 228 (1999), 10.1103/PhysRevE.59.228], is expected to be a pivotal feature of the frequency domain architectures of the higher-order members of the FDT hierarchy. On this premise, each member, in its most tractable form, connects a single (p +1 )-point dynamical structure function to a linear combination of (p +1 )-order p density response functions; by definition, such a combination must also remain invariant under rotation of their (k1,ω1) ,(k2,ω2) ,...,(kp,ωp) , (k1+k2+⋯+kp,ω1+ω2+⋯+ωp) 4-vector arguments. Assigned to each 4-vector is a species index that corotates in lock step. Consistency is assured by matching the static limits of the resulting frequency domain cubic and quartic FDTs to their exact static counterparts independently derived in the present work via a conventional time-independent perturbation expansion of the Liouville distribution function in its macrocanonical form. The proposed procedure entirely circumvents the daunting issues of entangled Liouville space paths and nested Poisson brackets that one would encounter if one attempted to use the conventional time-dependent perturbation-theoretic Kubo approach to establish the frequency domain FDTs beyond quadratic order.

Higher-order gravity in higher dimensions: geometrical origins of four-dimensional cosmology?

Energy Technology Data Exchange (ETDEWEB)

Determining the cosmological field equations is still very much debated and led to a wide discussion around different theoretical proposals. A suitable conceptual scheme could be represented by gravity models that naturally generalize Einstein theory like higher-order gravity theories and higher-dimensional ones. Both of these two different approaches allow one to define, at the effective level, Einstein field equations equipped with source-like energy-momentum tensors of geometrical origin. In this paper, the possibility is discussed to develop a five-dimensional fourth-order gravity model whose lower-dimensional reduction could provide an interpretation of cosmological four-dimensional matter-energy components. We describe the basic concepts of the model, the complete field equations formalism and the 5-D to 4-D reduction procedure. Five-dimensional f(R) field equations turn out to be equivalent, on the four-dimensional hypersurfaces orthogonal to the extra coordinate, to an Einstein-like cosmological model with three matter-energy tensors related with higher derivative and higher-dimensional counter-terms. By considering the gravity model with f(R) = f{sub 0}R{sup n} the possibility is investigated to obtain five-dimensional power law solutions. The effective four-dimensional picture and the behaviour of the geometrically induced sources are finally outlined in correspondence to simple cases of such higher-dimensional solutions. (orig.)

Mitigation strategies aimed at an intervention in the reaction pathways for furan formation (e.g., by adjusting precursor concentrations) might offer an additional route for furan reduction in sterilised, vegetable-based foods, without adverse effects on other food safety or quality attributes. As a first step towards product reformulation, the aim of the present study was to determine the relative importance and interactions of possible furan precursors in these types of foods. Based on an I-optimal experimental design, potato purée (naturally low in furan precursors) was spiked with known amounts of sugars, ascorbic acid, olive oil and β-carotene, and subjected to a thermal sterilisation. Significant correlations were observed between furan concentrations after thermal treatment and starting concentrations of ascorbic acid and monosaccharides (i.e., fructose and glucose). Ascorbic acid had a clear furan-reducing effect as an antioxidant by protecting (polyunsaturated) fatty acids against oxidative degradation. Fructose and glucose were the main precursors, which can most probably be attributed to their high, but realistic, concentrations in the product. The contributions of fatty acids and β-carotene were strongly dependent on redox interactions with other food constituents. In the same potato purées, only low concentrations (0-2 ng g(-1) purée) of 2-methylfuran were detected, indicating that the direct importance of the spiked food constituents as a precursor for methylfuran formation was rather small. Based on the results of this study, reducing the amount of monosaccharides or adjusting the redox conditions of the matrix are suggested as two possible approaches for furan mitigation on the product side.

Relative Importance and Knowledge Distribution of Medicinal Plants in a Kichwa Community in the Ecuadorian Amazon

2017-01-01

Full Text Available Traditional knowledge, such as knowledge of the use of plants as medicine, influences how indigenous people manage forest resources. Gender and age-associated differences in traditional knowledge may impact forest resource management because of the traditional division of labor. We interviewed 18 men and 18 women between 9 and 74 years old in San José de Payamino, an indigenous community of the Kichwa ethnicity in the Ecuadorian Amazon, to determine if there are gender or age-associated differences in medicinal plant knowledge among the Payamino people and to identify the most important species from a sample of medicinal plants. Individuals were interviewed using a tablet that displayed images of 34 plants, which had been cited by traditional healers in the community. Quantitative analysis provided insight into the relative importance of plants in the sample as well as the distribution of medicinal plant knowledge among members of the community. The most important plants were Tradescantia zanonia and Monolena primuliflora. These plants should be considered candidates for further investigation. There was a positive correlation between age and knowledge of medicinal plants, but no significant difference between genders. Our results suggest that an interview method that relies on digital images can reveal differences in the importance of medicinal plants as well as provide insight into the distribution of traditional medical knowledge. While men and women are likely to manage forest resources similarly, younger members of the community may not have the same regard for forest resources as their elder counterparts.

Purpose: The tumor suppressor p53 plays an essential role in cellular responses to DNA damage caused by ionizing radiation; therefore, this study aims to further explore the role that p53 plays at different doses of radiation. Materials and Methods: The global cellular responses to higher-dose (10 Gy) and lower dose (iso-survival dose, i.e., the respective D0 levels) radiation were analyzed using microarrays in three human lymphoblast cell lines with different p53 status: TK6 (wild-type p53), NH32 (p53-null), and WTK1 (mutant p53). Total RNAs were extracted from cells harvested at 0, 1, 3, 6, 9, and 24 h after higher and lower dose radiation exposures. Template-based clustering, hierarchical clustering, and principle component analysis were applied to examine the transcriptional profiles. Results: Differential expression profiles between 10 Gy and iso-survival radiation in cells with different p53 status were observed. Moreover, distinct gene expression patterns were exhibited among these three cells after 10 Gy radiation treatment, but similar transcriptional responses were observed in TK6 and NH32 cells treated with iso-survival radiation. Conclusions: After 10 Gy radiation exposure, the p53 signaling pathway played an important role in TK6, whereas the NFkB signaling pathway appeared to replace the role of p53 in WTK1. In contrast, after iso-survival radiation treatment, E2F4 seemed to play a dominant role independent of p53 status. This study dissected the impacts of p53, NFkB and E2F4 in response to higher or lower doses of γ-irradiation.

Climate changes are considered to significantly impact net primary productivity (NPP). However, there are few studies on how climate changes at multiple time scales impact NPP. With MODIS NPP product and station-based observations of sunshine duration, annual average temperature and annual precipitation, impacts of climate changes at different time scales on annual NPP, have been studied with EEMD (ensemble empirical mode decomposition) method in the Karst area of northwest Guangxi, China, during 2000-2013. Moreover, with partial least squares regression (PLSR) model, the relative importance of climatic variables for annual NPP has been explored. The results show that (1) only at quasi 3-year time scale do sunshine duration and temperature have significantly positive relations with NPP. (2) Annual precipitation has no significant relation to NPP by direct comparison, but significantly positive relation at 5-year time scale, which is because 5-year time scale is not the dominant scale of precipitation; (3) the changes of NPP may be dominated by inter-annual variabilities. (4) Multiple time scales analysis will greatly improve the performance of PLSR model for estimating NPP. The variable importance in projection (VIP) scores of sunshine duration and temperature at quasi 3-year time scale, and precipitation at quasi 5-year time scale are greater than 0.8, indicating important for NPP during 2000-2013. However, sunshine duration and temperature at quasi 3-year time scale are much more important. Our results underscore the importance of multiple time scales analysis for revealing the relations of NPP to changing climate.

Analogy, higher order thinking, and education.

Science.gov (United States)

Richland, Lindsey Engle; Simms, Nina

2015-01-01

Analogical reasoning, the ability to understand phenomena as systems of structured relationships that can be aligned, compared, and mapped together, plays a fundamental role in the technology rich, increasingly globalized educational climate of the 21st century. Flexible, conceptual thinking is prioritized in this view of education, and schools are emphasizing 'higher order thinking', rather than memorization of a cannon of key topics. The lack of a cognitively grounded definition for higher order thinking, however, has led to a field of research and practice with little coherence across domains or connection to the large body of cognitive science research on thinking. We review literature on analogy and disciplinary higher order thinking to propose that relational reasoning can be productively considered the cognitive underpinning of higher order thinking. We highlight the utility of this framework for developing insights into practice through a review of mathematics, science, and history educational contexts. In these disciplines, analogy is essential to developing expert-like disciplinary knowledge in which concepts are understood to be systems of relationships that can be connected and flexibly manipulated. At the same time, analogies in education require explicit support to ensure that learners notice the relevance of relational thinking, have adequate processing resources available to mentally hold and manipulate relations, and are able to recognize both the similarities and differences when drawing analogies between systems of relationships. © 2015 John Wiley & Sons, Ltd.

Higher Education and Equality of Opportunitly:A Survey of Recent Cross-National Research

Directory of Open Access Journals (Sweden)

Fred A.Lazin

2012-01-01

Full Text Available Rising costs of education at the start of the 21st century seem to indicate a stark shift in education policies, which raises several important questions. The author shows that from the United States to East Asia and Australia – seemingly everywhere – higher education policy is headed in the same direction. The movement to broaden access to public universities, the dominant strategy during the 1970s and 1980s, has largely shifted to enable the marketplace, rather than the government, to shape the contours of higher education. Government funding is being reduced, affirmative action and other programs designed to insure broader access are in decline, and personal fulfilment is replacing a public good designed to insure greater equality of opportunity. The author describes how this sea of change in higher education has played out in economically developed and developing countries. In trying to provide the answer to the above-mentioned development, the author raises the question related to the consequences of a market-driven higher education for student access, teaching and scholarship.

Although obesity is associated with hepatocellular carcinoma (HCC) development, its impact on the surgical outcomes of patients with hepatitis B virus (HBV)-and hepatitis C virus (HCV)-related HCC remains unclear. We retrospectively analyzed 714 patients with HCC who underwent curative hepatectomy. Among them, the HBV-related HCC group (n = 125) and HCV-related HCC group (n = 426) were subdivided according to the presence of body mass index (BMI) ≥ 25 kg/m 2 . The surgical outcomes were compared. The 5-year overall survival rate after hepatectomy in the HBV-related HCC group was significantly better than that in the HCV-related HCC group. The 5-year overall survival rates of the HBV-related HCC with and without BMI ≥ 25 kg/m 2 groups were 65 and 85%, respectively. The 5-year overall survival rates in the HCV-related HCC with and without BMI ≥ 25 kg/m 2 groups were 75 and 65%, respectively. The HBV-related HCC with BMI ≥ 25 kg/m 2 groups had a significantly worse prognosis than the HBV-related HCC without BMI ≥ 25 kg/m 2 groups, while the HCV-related HCC with BMI ≥ 25 kg/m 2 groups had a significantly better prognosis than the HCV-related HCC without BMI ≥ 25 kg/m 2 groups. Multivariate analysis revealed that BMI ≥ 25 kg/m 2 was the positive and negative prognostic factor for the surgical outcomes of patients with HBV- and HCV-related HCC, respectively. BMI ≥ 25 kg/m 2 negatively affected the surgical outcomes of patients with HBV-related HCC and positively affected those of patients with HCV-related HCC.

To identify predictors of relational coordination among professionals delivering care to older patients. Relational coordination is known to enhance quality of care in hospitals. The underlying mechanisms, however, remain poorly understood. This cross-sectional study was part of a larger evaluation study examining the opportunity to prevent loss of function in older patients due to hospitalization in the Netherlands. This study was performed in spring 2010 among team members delivering care to older hospitalized patients (192 respondents; 44% response rate) in one hospital. Relational coordination was measured by the Relational Coordination survey; team climate by the Team Climate Inventory and questions were asked about participation in multidisciplinary team meetings and disciplines represented in these meetings. To account for the hierarchical structure, a multilevel analysis was performed. Correlation analysis revealed a positive relationship among being female, being a nurse and relational coordination; medical specialists showed a negative relationship. The number of disciplines represented during multidisciplinary team meetings and team climate were positively related with relational coordination. The multilevel analysis showed a positive relationship between the number of disciplines represented during multidisciplinary team meetings and team climate with relational coordination. The enhancement of team climate and attendance of diverse professionals during multidisciplinary team meetings are expected to improve relational coordination. Furthermore, this study underscores the importance of enhancing relational coordination between medical specialists and other professionals. © 2013 The Authors.

2013-07-01

Full Text Available The main aim of this paper is to know the opinion of the university stakeholders regarding the importance they give to intellectual capital reporting. To this end, a questionnaire was designed and sent to every member of the Social Councils of Spanish public universities. The results of our empirical study show that the current annual accounts published by universities barely cover the information needs of the different stakeholders. These results allow us to recommend extending the limits of universities’ annual accounts so as to include the information on intellectual capital demanded by the different stakeholders. In our opinion, the traditional accounting systems do not suffice for higher education institutions, whose value creation depends more on intellectual capital type resources. Finally, this empirical study identifies which of components of intellectual capital (human, structural and relation is the most relevant for publication. The results show that the information most valued by the different stakeholder groups is that related to relational capital, followed by human and then lastly structural capital.

O'Boyle, Ernest H; Forsyth, Donelson R; Banks, George C; Story, Paul A; White, Charles D

2015-12-01

We examined the relationships between Machiavellianism, narcissism, and psychopathy-the three traits of the Dark Triad (DT)-and the Five-Factor Model (FFM) of personality. The review identified 310 independent samples drawn from 215 sources and yielded information pertaining to global trait relationships and facet-level relationships. We used meta-analysis to examine (a) the bivariate relations between the DT and the five global traits and 30 facets of the FFM, (b) the relative importance of each of the FFM global traits in predicting DT, and (c) the relationship between the DT and FFM facets identified in translational models of narcissism and psychopathy. These analyses identified consistent and theoretically meaningful associations between the DT traits and the facets of the FFM. The five traits of the FFM, in a relative importance analysis, accounted for much of the variance in Machiavellianism, narcissism, and psychopathy, respectively, and facet-level analyses identified specific facets of each FFM trait that were consistently associated with narcissism (e.g., angry/hostility, modesty) and psychopathy (e.g., straightforwardness, deliberation). The FFM explained nearly all of the variance in psychopathy (R(2) c  = .88) and a substantial portion of the variance in narcissism (R(2) c  = .42). © 2014 Wiley Periodicals, Inc.

Imported malaria cases continue to occur and are often underreported. This study assessed reporting of malaria cases and their characteristics in Scotland. Cases were identified at the study sites of Aberdeen, Edinburgh, Glasgow and Inverness. The number of cases identified in the period 2003-2008 was compared to surveillance databases from Health Protection Scotland (HPS) and the Malaria Reference Laboratory (MRL). Case characteristics were recorded and analysed. Of 252 cases of malaria diagnosed and treated, an estimated 235 (93.3%) were reported to the MRL. Between 2006 and 2008, 114 of 126 cases (90.5%) were reported to HPS. Plasmodium falciparum caused 173 cases (68.7%). Business and professional travel accounted for 35.3% of cases (higher in Aberdeen), followed by visiting friends and relatives (33.1%) and holiday makers (25.5%). The majority of infections were imported from West Africa and 65.7% of patients for whom data on prophylaxis was available had taken no or inappropriate prophylaxis. Reporting of malaria in Scotland can be improved. There is a continued need to optimise preventive measures and adherence to chemoprophylaxis amongst business travellers, those visiting friends and relatives, and holiday makers in endemic countries in order to reduce imported malaria cases.

The relative importance of climate and vegetation properties on patterns of North American breeding bird species richness

International Nuclear Information System (INIS)

Goetz, Scott J; Sun, Mindy; Zolkos, Scott; Hansen, Andy; Dubayah, Ralph

2014-01-01

Recent advances in remote sensing and ecological modeling warrant a timely and robust investigation of the ecological variables that underlie large-scale patterns of breeding bird species richness, particularly in the context of intensifying land use and climate change. Our objective was to address this need using an array of bioclimatic and remotely sensed data sets representing vegetation properties and structure, and other aspects of the physical environment. We first build models of bird species richness across breeding bird survey (BBS) routes, and then spatially predict richness across the coterminous US at moderately high spatial resolution (1 km). Predictor variables were derived from various sources and maps of species richness were generated for four groups (guilds) of birds with different breeding habitat affiliation (forest, grassland, open woodland, scrub/shrub), as well as all guilds combined. Predictions of forest bird distributions were strong (R 2 = 0.85), followed by grassland (0.76), scrub/shrub (0.63) and open woodland (0.60) species. Vegetation properties were generally the strongest determinants of species richness, whereas bioclimatic and lidar-derived vertical structure metrics were of variable importance and dependent upon the guild type. Environmental variables (climate and the physical environment) were also frequently selected predictors, but canopy structure variables were not as important as expected based on more local to regional scale studies. Relatively sparse sampling of canopy structure metrics from the satellite lidar sensor may have reduced their importance relative to other predictor variables across the study domain. We discuss these results in the context of the ecological drivers of species richness patterns, the spatial scale of bird diversity analyses, and the potential of next generation space-borne lidar systems relevant to vegetation and ecosystem studies. This study strengthens current understanding of bird species�

2007-12-01

Full Text Available The purpose of this research was to establish the level of importance attached to competitive intelligence (CI at a mass import retail organization in South Africa. The rationale of CI is to alert an organization about the current situation as it relates to its business environment and competitors, and how these aspects affect the competitive situation. In this article, the value and significance that CI presents to organizations upon implementation are discussed by focusing upon the need for a competitive strategy, the significance of institutionalizing CI, various organizational structure options and the establishment of a CI culture. A survey was conducted at a mass import retail organization to determine the level of importance attached to CI. A total of 107 employees were randomly selected to participate in the completion of a questionnaire. Based on the results, it was found that this organization practised CI, albeit in an informal manner, and it was concluded that there was a relatively high level of importance attached to CI within this organization. However, areas for improvement were identified and a recommendation was made of implementing a formal CI function within the organization.

This study examines the relative importance of individual differences in relation to perceptions of work-family conflict and facilitation, as well as the moderating role of boundary preference for segmentation on these relationships. Relative importance analyses, based on a diverse sample of 380 employees from the USA, revealed that individual differences were consistently predictive of self-reported work-family conflict and facilitation. Conscientiousness, neuroticism, negative affect and core self-evaluations were consistently related to both directions of work-family conflict, whereas agreeableness predicted significant variance in family-to-work conflict only. Positive affect and core self-evaluations were consistently related to both directions of work-family facilitation, whereas agreeableness and neuroticism predicted significant variance in family-to-work facilitation only. Collectively, individual differences explained 25-28% of the variance in work-family conflict (primarily predicted by neuroticism and negative affect) and 11-18% of the variance in work-family facilitation (primarily predicted by positive affect and core self-evaluations). Moderated regression analyses showed that boundary preference for segmentation strengthened many of the relationships between individual differences and work-family conflict and facilitation. Implications for addressing the nature of work and family are discussed. Copyright © 2012 John Wiley & Sons, Ltd.

The elusive importance effect: more failure for the Jamesian perspective on the importance of importance in shaping self-esteem.

Science.gov (United States)

Marsh, Herbert W

2008-10-01

Following William James (1890/1963), many leading self-esteem researchers continue to support the Individual-importance hypothesis-that the relation between specific facets of self-concept and global self-esteem depends on the importance an individual places on each specific facet. However, empirical support for the hypothesis is surprisingly elusive, whether evaluated in terms of an importance-weighted average model, a generalized multiple regression approach for testing self-concept-by-importance interactions, or idiographic approaches. How can actual empirical support for such an intuitively appealing and widely cited psychological principle be so elusive? Hardy and Moriarty (2006), acknowledging this previous failure of the Individual-importance hypothesis, claim to have solved the conundrum, demonstrating an innovative idiographic approach that provides clear support for it. However, a critical evaluation of their new approach, coupled with a reanalysis of their data, undermines their claims. Indeed, their data provide compelling support against the Individual-importance hypothesis, which remains as elusive as ever.

Full Text Available The paper aims at analyzing the dynamics of in Romanian higher education graduates in the 2006-2010 period, both in Romania and by the Romanian development regions. After highlighting the importance of human capital and its education, the paper analyzes the dynamics of Romanian higher education graduates in the targeted period, at both of the above-mentioned levels. The conclusions reveal that, during the analysed period: 2006-2010, the number of female, and, respectively, male higher education graduates, as well as the total number of higher education graduates, continuously increased in the 2006-2010 period at the whole country level and registered an increase trend, as well, by the eight development regions of Romania in the 2006-2010 period, with very few exceptions in some years of the period, in some of the the eight development regions of Romania. Therefore, the Romanian higher education system must correlate the graduates number with the number of work places in the Romanian economy, and take into account the necessities imposed by the participation at international competition.

The Relative Importance of Spatial and Local Environmental Factors in Determining Beetle Assemblages in the Inner Mongolia Grassland.

Directory of Open Access Journals (Sweden)

Xiao-Dong Yu

Full Text Available The aim of this paper is to increase understanding of the relative importance of the input of geographic and local environmental factors on richness and composition of epigaeic steppe beetles (Coleoptera: Carabidae and Tenebrionidae along a geographic (longitudinal/precipitation gradient in the Inner Mongolia grassland. Specifically, we evaluate the associations of environmental variables representing climate and environmental heterogeneity with beetle assemblages. Beetles were sampled using pitfall traps at 25 sites scattered across the full geographic extent of the study biome in 2011-2012. We used variance partitioning techniques and multi-model selection based on the Akaike information criterion to assess the relative importance of the spatial and environmental variables on beetle assemblages. Species richness and abundance showed unimodal patterns along the geographic gradient. Together with space, climate variables associated with precipitation, water-energy balance and harshness of climate had strong explanatory power in richness pattern. Abundance pattern showed strongest association with variation in temperature and environmental heterogeneity. Climatic factors associated with temperature and precipitation variables and the interaction between climate with space were able to explain a substantial amount of variation in community structure. In addition, the turnover of species increased significantly as geographic distances increased. We confirmed that spatial and local environmental factors worked together to shape epigaeic beetle communities along the geographic gradient in the Inner Mongolia grassland. Moreover, the climate features, especially precipitation, water-energy balance and temperature, and the interaction between climate with space and environmental heterogeneity appeared to play important roles on controlling richness and abundance, and species compositions of epigaeic beetles.

Optimal growth and development in early childhood is determined by a complex interplay of child, maternal, household, environmental, and socioeconomic factors that influence nutritional intake, but interventions to reduce child undernutrition sometimes target specific risk factors in isolation. In this analysis, we assess the relative importance of 13 correlates of child stunting selected based on a collective review of existing multi-factorial frameworks: complementary feeding, breastfeeding, feeding frequency, dietary diversity, maternal height, body mass index (BMI), education, age at marriage, child vaccination, access to improved drinking source and sanitation facilities, household indoor air quality, and household wealth. The analytic sample consisted of nationally representative cross-sectional surveys from the most recent Demographic and Health Surveys for Bangladesh (2014), India (2005), Nepal (2011), and Pakistan (2013), and from the National Nutrition Survey for Afghanistan (2013). In the mutually adjusted logistic regression model for 3,159 infants aged 6-8 months, short maternal stature (OR: 2.93; 95% CI: 1.93-4.46) and lack of complementary foods (OR: 1.47; 95% CI: 1.12-1.93) were associated with significantly higher risk of stunting. For 18,586 children aged 6-23 months, the strongest correlates of child stunting were: maternal height (OR: 3.37, 95% CI: 2.82-4.03), household wealth (OR: 2.25, 95% CI: 1.72-2.94), maternal BMI (OR: 1.59, 95% CI: 1.27-2.00), minimum dietary diversity (OR: 1.48, 95% CI: 1.27-1.72), maternal education (OR: 1.36, 95% CI: 1.18-1.56), and age at marriage (OR: 1.17, 95% CI: 1.05-1.30). Full vaccination and minimum dietary frequency were also found to be important for severe stunting for children of this age group. Some differences were found in the relative ordering and statistical significance of the correlates in country-specific analyses. Our findings indicate that comprehensive strategies incorporating a broader progress

Optimizer convergence and local minima errors and their clinical importance

International Nuclear Information System (INIS)

Jeraj, Robert; Wu, Chuan; Mackie, Thomas R

2003-01-01

Two of the errors common in the inverse treatment planning optimization have been investigated. The first error is the optimizer convergence error, which appears because of non-perfect convergence to the global or local solution, usually caused by a non-zero stopping criterion. The second error is the local minima error, which occurs when the objective function is not convex and/or the feasible solution space is not convex. The magnitude of the errors, their relative importance in comparison to other errors as well as their clinical significance in terms of tumour control probability (TCP) and normal tissue complication probability (NTCP) were investigated. Two inherently different optimizers, a stochastic simulated annealing and deterministic gradient method were compared on a clinical example. It was found that for typical optimization the optimizer convergence errors are rather small, especially compared to other convergence errors, e.g., convergence errors due to inaccuracy of the current dose calculation algorithms. This indicates that stopping criteria could often be relaxed leading into optimization speed-ups. The local minima errors were also found to be relatively small and typically in the range of the dose calculation convergence errors. Even for the cases where significantly higher objective function scores were obtained the local minima errors were not significantly higher. Clinical evaluation of the optimizer convergence error showed good correlation between the convergence of the clinical TCP or NTCP measures and convergence of the physical dose distribution. On the other hand, the local minima errors resulted in significantly different TCP or NTCP values (up to a factor of 2) indicating clinical importance of the local minima produced by physical optimization

Family and twin studies suggest that development of thyroid autoantibodies in first-degree relatives of patients with autoimmune thyroi....... The analyses suggest that it is the same set of genes that operate in males and females. However, complex mechanisms such as dominance and/or epistasis may be involved....... concordance and intraclass correlations were consistently higher for MZ than for DZ twin pairs indicating genetic influence. Genetic components (with 95% confidence intervals) accounted for 73% (46-89%) of the liability of being thyroid antibody positive. Adjusting for covariates (age, TSH and others......), the estimate for genetic influence on serum TPOab concentrations was 61% (49-70%) in males and 72% (64-79%) in females. For serum Tgab concentrations, the estimates were 39% (24-51%) and 75% (66-81%) respectively. CONCLUSIONS: Early markers of thyroid autoimmunity appear to be under strong genetic influence...

Who gets a job after graduation? Factors affecting the early career employment chances of higher education graduates in Poland

Directory of Open Access Journals (Sweden)

Mikołaj Jasiński

2017-12-01

Full Text Available The massification of higher education in Poland means that many students choose this educational pathway to improve their chances for a good job. Therefore, the labour market outcomes of graduates provide an important perspective for future students, higher education institutions, as well as decision makers at the national level. The Polish Graduate Tracking System (ELA, based on administrative data, is designed to monitor graduates’ outcomes in the labour market by type of studies, higher education institution, as well as individual curricula. Results of the first two years of graduate tracking show that the outcomes vary by study area, but also change over time. While in the first months after graduation, aspects such as prior experience in the labour market and place of residence have a substantial effect on employment chances, in the longer run, they lose their importance relative to other factors.

First and higher order, heuristically based generalized perturbation theory (HGPT) with optional control reset variable

International Nuclear Information System (INIS)

Gandini, A.

1996-01-01

The heuristically based generalized perturbation theory (HGPT), to first and higher order, applied to the neutron field of a reactor system, is discussed in relation to the criticality reset procedure. This procedure is implicit within the GPT methodology, corresponding to the so called filtering of the importance function relevant to the neutron field from the fundamental mode contamination. It is common practice to use the so called ''lambda''-mode filter. In order to account for any possible reset option, a general definition is introduced of an intensive control variable (ρ) entering into the governing equations, and correspondingly a fundamental ρ-mode filtering of the importance function is defined, relevant to the real criticality reset (control) mechanism adopted. A simple example illustrates the need to take into account the correct filtering, so as to avoid significant inaccuracies in the sensitivity calculation results. The extension of this filtering technique to other functions entering into the GPT perturbative formulations at first and higher order is also discussed. (author)

2015-10-01

Athletes' precompetitive appraisal is important because it determines emotions, which may impact performance. When part of a team, athletes make their appraisal within a social context, and in this study we examined whether perceived team cohesion, as a characteristic of this context, related to appraisal. We asked 386 male and female intercollegiate team-sport athletes to respond to measures of cohesion and precompetitive appraisal before an in-season game. For males and females, across all teams, (a) an appraisal of increased competition importance was predicted by perceptions of higher task cohesion (individual level), better previous team performance, and a weaker opponent (team level) and (b) an appraisal of more positive prospects for coping with competitive demands was predicted by higher individual attractions to the group (individual level). Consequently, athletes who perceive their team as more cohesive likely appraise the pending competition as a challenge, which would benefit both emotions and performance.

Full Text Available Economy in Bosnia and Herzegovina is striving towards growth and increased employment and it has been proven by empirical studies worldwide that higher education contributes to socio-economic development of a country. Universities are important for generation, preservation and dissemination of knowledge in order to contribute to socio-economic benefits of a country. Higher education institutions are being pressured to improve value for their activities and providing quality higher education service to students should be taken seriously. In this paper we will address the emerging demand for quality in higher education. Higher education institutions should assess quality of their services and establish methods for improving quality. Activities of quality assurance should be integrated into the management process at higher education institutions. This paper is addressing the issue of service quality measurement in higher education institutions. The most frequently used model in this context is the SERVQUAL model. This model is measuring quality from the students' point of view, since students are considered to be one of the most important stakeholders for a higher education institution. The main objective of this research is to provide empirical evidence that the adapted SERVQAL model can be used in higher education and to identify the service quality gap based on its application at one institution of higher education (Faculty of Economics in Bosnia and Herzegovina. Furthermore, results of the gap analysis using the SERVQUAL methodology provide relevant information in which areas improvement is necessary in order to enhance service quality.

Most published guidelines for environmental surveillance emphasize the collection and analysis of specific media (e.g. air, water, milk, direct radiation) without total regard for the potential dose impact of the radionuclides expected in or actually present in the effluent streams FR-om nuclear facilities. To determine the relative importance of medium/nuclide combinations in environmental surveillance, the experience at major ERDA sites and at operating nuclear power plants was reviewed. Typical release rates for nuclide groupings (tritium, noble gases, radioiodine, mixed fission or activation products, and transuranics) in those effluent streams were followed through various environmental pathways. By using this scheme the environmental medium which is most prominent in the critical dose pathway to man was determined. It was also possible to determine points of short-or long-term contaminant accumulation. Following these combination providing the relative importance of sampling specific environmental media with emphasis on the radiation dose to a critical population group. Finally, the results of these environmental pathway studies are presented in tabular form to provide ready reference for environmental surveillance program design or evaluation

Purpose Vision loss from age-related macular degeneration (AMD) has a profound effect on vision-related quality of life (VRQoL). The pupose of this study is to identify clinical factors associated with VRQoL using the Rasch- calibrated NEI VFQ-25 scales in bilateral advanced AMD patients. Methods We retrospectively reviewed 47 patients (mean age 83.2 years) with bilateral advanced AMD. Clinical assessment included age, gender, type of AMD, high contrast visual acuity (VA), history of medical conditions, contrast sensitivity (CS), central visual field loss, report of Charles Bonnet Syndrome, current treatment for AMD and Rasch-calibrated NEI VFQ-25 visual function and socioemotional function scales. The NEI VFQ visual function scale includes items of general vision, peripheral vision, distance vision and near vision-related activity while the socioemotional function scale includes items of vision related-social functioning, role difficulties, dependency, and mental health. Multiple regression analysis (structural regression model) was performed using fixed item parameters obtained from the one-parameter item response theory model. Results Multivariate analysis showed that high contrast VA and CS were two factors influencing VRQoL visual function scale (β = -0.25, 95% CI-0.37 to -0.12, p<0.001 and β = 0.35, 95% CI 0.25 to 0.46, p<0.001) and socioemontional functioning scale (β = -0.2, 95% CI -0.37 to -0.03, p = 0.023, and β = 0.3, 95% CI 0.18 to 0.43, p = 0.001). Central visual field loss was not assoicated with either VRQoL visual or socioemontional functioning scale (β = -0.08, 95% CI-0.28 to 0.12,p = 0.44 and β = -0.09, 95% CI -0.03 to 0.16, p = 0.50, respectively). Conclusion In patients with vision impairment secondary to bilateral advanced AMD, high contrast VA and CS are two important factors affecting VRQoL. PMID:29746512

Introduction Many children fail to meet international guideline recommendations for health-related activity (≥60 minutes/day of moderate-to-vigorous physical activity [MVPA]), and intervention studies to date have reported negligible effects. Objective Explore the associations of organized leisure-time sport participation with overall physical activity levels and health-related physical activity guideline concordance. Methods This prospective cohort study was nested in the Childhood Health, Activity, and Motor Performance School Study Denmark. Study participants were a representative sample of 1124 primary school students. Organized leisure-time sport participation was reported via text messaging and physical activity was objectively measured over seven days with accelerometry. Associations between sport participation and physical activity level were explored with multilevel mixed-effects regression models and reported with beta coefficients (b) and adjusted odds ratios (aOR). Results Participants were 53% female, with mean(SD) age = 8.4(1.4) years. Boys were more active than girls (psports (gymnastics, basketball, volleyball) were inconsistent. Conclusions Many children, particularly girls and those in higher grade levels do not adhere to health-related physical activity recommendations. Organized leisure-time sport participation may be a viable strategy to increase overall health-related physical activity levels and international guideline concordance in children. PMID:26262678

2017-10-01

Full Text Available In today’s global world and with the help of modern technology, English has become the most common and dominant language spoken and used both at the national and international levels. It has been playing a major role in many sectors as medicine, engineering, politics, economics, international relations, and higher education in particular, the most important area where English is needed. It has also become a medium of instruction at universities in a large number of countries, a basic means of second language learning / teaching, an accessing source of modern knowledge and scientific research, and a means of global communication and earn living. It is realized nowadays at the level of Higher Education in many countries around the world, in addition to EU countries as Germany, Turkey, China, Republic of Korea, Malaysia, Indonesia, Japan, Australian, India …, the significance of providing education in English side by side with their natives. Hence, serious steps have taken to improve the quality of instruction in English at the administrative, academic, students’, publications and research levels. And in order to prove English language international power, it goes beyond its tertiary. Many English language proficiency, training and degree programs are managed not only inside but also abroad for internationalization of higher education to keep it up to date. However, this paper signifies the role of English in modern education, particularly in higher education sector and the role of modern technology in promoting English language learning / teaching quality to meet the standards, communication needs and cultural exchange across the world.

Siddiqi, Ariba; Arjunan, Sridhar P; Kumar, Dinesh K

2016-08-01

Age-associated changes in the surface electromyogram (sEMG) of Tibialis Anterior (TA) muscle can be attributable to neuromuscular alterations that precede strength loss. We have used our sEMG model of the Tibialis Anterior to interpret the age-related changes and compared with the experimental sEMG. Eighteen young (20-30 years) and 18 older (60-85 years) performed isometric dorsiflexion at 6 different percentage levels of maximum voluntary contractions (MVC), and their sEMG from the TA muscle was recorded. Six different age-related changes in the neuromuscular system were simulated using the sEMG model at the same MVCs as the experiment. The maximal power of the spectrum, Gaussianity and Linearity Test Statistics were computed from the simulated and experimental sEMG. A correlation analysis at α=0.05 was performed between the simulated and experimental age-related change in the sEMG features. The results show the loss in motor units was distinguished by the Gaussianity and Linearity test statistics; while the maximal power of the PSD distinguished between the muscular factors. The simulated condition of 40% loss of motor units with halved the number of fast fibers best correlated with the age-related change observed in the experimental sEMG higher order statistical features. The simulated aging condition found by this study corresponds with the moderate motor unit remodelling and negligible strength loss reported in literature for the cohorts aged 60-70 years.

2016-12-01

Making assessments regarding postural control and balance is very important for injury prevention in soccer. However, there has been no study that has associated postural control variables with branch-specific technical properties in a game. The aim of the present study was to determine the relationships between variables designating postural control levels and technical performance variables in different (1:1, 2:2 and 3:3) small-sided games (SSGs). Sixteen trained male amateur soccer players volunteered to take part in the study (age 17.2 ± 1.02 years, body height 176.25 ± 0.07 m, body mass 67.67 ± 13.27 kg). Following familiarization sessions, postural control was evaluated using one-leg and both-leg quiet-stance positions by measuring postural sway with a Tekscan HR Mat™ in anterior-posterior and medial-lateral directions. Later, 1:1, 2:2 and 3:3 SSGs were performed at two-day intervals and the technical variables specified for each game were analyzed. A Spearman's rank-order correlation analysis demonstrated the relationship between postural control and soccer-specific technical variables in 1:1 (r-values ranging from 0.582 to 0.776), 2:2 (rvalues ranging from 0.511 to 0.740) and 3:3 (r-values ranging from 0.502 to 0.834) SSGs. In addition, a Wilcoxon signed rank test revealed differences between SSGs in terms of several variables. The results of the study showed that higher postural control levels are among the important variables that affect success in the performance of technical skills under rival pressure and suddenly changing conditions. Therefore, it is recommended that in addition to its use for injury prevention purposes, balance training should be conducted to improve branch-specific technical skills and to increase the levels of their successful performance in a game.

RE-LEARNING HIGHER EDUCATION IN THE AGE OF CONVERGENCE: Example of Lithuania

Full Text Available “Man is the only being who needs education,” and that "Man can only become man by education" (see footnotes 1 ABSTRACT Since May of 1999, 46 European countries have been engaged in reconstructing their higher education systems to bring about a greater degree of “convergence,” i.e. a move toward common reference points and operating procedures to create a European Higher Education Area. Education has always played an important role in the development of Lithuania, with long and strong traditions as a country with highly educated scientists and cutting-edge research in various fields. In April 2009, the Seimas passed a new Law on Science and Studies, which provides for a major reform of higher education. In recent years there has been an increasing focus on the role universities play in the economy and impact they make in promoting innovation and raising international competitiveness. But until recently there has been a prescriptive view of university-business interactions with a narrow focus on technology transfer. Although technology transfer may be important, it is also necessary to focus on the more diverse and varied impacts of business-university knowledge exchange relations. Thus, I discuss changes in higher education that were implemented in Lithuania during the period of 1992-2012, i. e. Student baskets, notorious optimization of university network in Lithuania, the development of Lithuanian science valleys, etc. In my survey I rely upon an IHEP (Institute for Higher Education Policy expert Cliff Adelman’s idea that the Bologna Process is an analogue to the macroeconomic theory of convergence, the ways in which nations move from different stages of development to a more-or-less common platform of performance. Macroeconomic historians have demonstrated time-and-again: nations that learn from other nations grow; those that do not learn do not. Ultimately, I arrive at a conclusion that reforms are essential and indispensable but

Laugesen, Miriam J; Glied, Sherry A

Higher health care prices in the United States are a key reason that the nation's health spending is so much higher than that of other countries. Our study compared physicians' fees paid by public and private payers for primary care office visits and hip replacements in Australia, Canada, France, Germany, the United Kingdom, and the United States. We also compared physicians' incomes net of practice expenses, differences in financing the cost of medical education, and the relative contribution of payments per physician and of physician supply in the countries' national spending on physician services. Public and private payers paid somewhat higher fees to US primary care physicians for office visits (27 percent more for public, 70 percent more for private) and much higher fees to orthopedic physicians for hip replacements (70 percent more for public, 120 percent more for private) than public and private payers paid these physicians' counterparts in other countries. US primary care and orthopedic physicians also earned higher incomes ($186,582 and $442,450, respectively) than their foreign counterparts. We conclude that the higher fees, rather than factors such as higher practice costs, volume of services, or tuition expenses, were the main drivers of higher US spending, particularly in orthopedics.

Autophagy-Related Direct Membrane Import from ER/Cytoplasm into the Vacuole or Apoplast: A Hidden Gateway also for Secondary Metabolites and Phytohormones?

Directory of Open Access Journals (Sweden)

Full Text Available Transportation of low molecular weight cargoes into the plant vacuole represents an essential plant cell function. Several lines of evidence indicate that autophagy-related direct endoplasmic reticulum (ER to vacuole (and also, apoplast transport plays here a more general role than expected. This route is regulated by autophagy proteins, including recently discovered involvement of the exocyst subcomplex. Traffic from ER into the vacuole bypassing Golgi apparatus (GA acts not only in stress-related cytoplasm recycling or detoxification, but also in developmentally-regulated biopolymer and secondary metabolite import into the vacuole (or apoplast, exemplified by storage proteins and anthocyanins. We propose that this pathway is relevant also for some phytohormones’ (e.g., auxin, abscisic acid (ABA and salicylic acid (SA degradation. We hypothesize that SA is not only an autophagy inducer, but also a cargo for autophagy-related ER to vacuole membrane container delivery and catabolism. ER membrane localized enzymes will potentially enhance the area of biosynthetic reactive surfaces, and also, abundant ER localized membrane importers (e.g., ABC transporters will internalize specific molecular species into the autophagosome biogenesis domain of ER. Such active ER domains may create tubular invaginations of tonoplast into the vacuoles as import intermediates. Packaging of cargos into the ER-derived autophagosome-like containers might be an important mechanism of vacuole and exosome biogenesis and cytoplasm protection against toxic metabolites. A new perspective on metabolic transformations intimately linked to membrane trafficking in plants is emerging.

Value change in oil and gas production: V. Incorporation of uncertainties and determination of relative importance

International Nuclear Information System (INIS)

Lerche, I.; Noeth, S.

2002-01-01

The influence of two fundamentally different types of uncertainty on the value of oil field production are investigated here. First considered is the uncertainty caused by the fact that the expected value estimate is not one of the possible outcomes. To correctly allow for the risk attendant upon using the expected value as a measure of worth, even with statistically sharp parameters, one needs to incorporate the uncertainty of the expected value. Using a simple example we show how such incorporation allows for a clear determination of the relative risk of projects that may have the same expected value but very different risks. We also show how each project can be risked on its own using the expected value and variance. This uncertainty type is due to the possible pathways for different outcomes even when parameters categorizing the system are taken to be known. Second considered is the risk due to the fact that parameters in oil field estimates are just estimates and, as such, have their own intrinsic errors that influence the possible outcomes and make them less certain. This sort of risk depends upon the uncertainty of each parameter, and also the type of distribution the parameters are taken to be drawn from. In addition, not all uncertainties in parameters values are of equal importance in influencing an outcome probability. We show how can determine the relative importance for the parameters and so determine where to place effort to resolve the dominant contributions to risk if it is possible to do so. Considerations of whether to acquire new information, and also whether to undertake further studies under such an uncertain environment, are used as vehicles to address these concerns of risk due to uncertainty. In general, an oil field development project has to contend with all the above types of risk and uncertainty. It is therefore of importance to have quantitative measures of risk so that one can compare and contrast the various effects, and so that

An estimation of crude oil import demand in Turkey: Evidence from time-varying parameters approach

International Nuclear Information System (INIS)

Ozturk, Ilhan; Arisoy, Ibrahim

2016-01-01

The aim of this study is to model crude oil import demand and estimate the price and income elasticities of imported crude oil in Turkey based on a time-varying parameters (TVP) approach with the aim of obtaining accurate and more robust estimates of price and income elasticities. This study employs annual time series data of domestic oil consumption, real GDP, and oil price for the period 1966–2012. The empirical results indicate that both the income and price elasticities are in line with the theoretical expectations. However, the income elasticity is statistically significant while the price elasticity is statistically insignificant. The relatively high value of income elasticity (1.182) from this study suggests that crude oil import in Turkey is more responsive to changes in income level. This result indicates that imported crude oil is a normal good and rising income levels will foster higher consumption of oil based equipments, vehicles and services by economic agents. The estimated income elasticity of 1.182 suggests that imported crude oil consumption grows at a higher rate than income. This in turn reduces oil intensity over time. Therefore, crude oil import during the estimation period is substantially driven by income. - Highlights: • We estimated the price and income elasticities of imported crude oil in Turkey. • Income elasticity is statistically significant and it is 1.182. • The price elasticity is statistically insignificant. • Crude oil import in Turkey is more responsive to changes in income level. • Crude oil import during the estimation period is substantially driven by income.

Relative Importance of Human Resource Practices on Affective Commitment and Turnover Intention in South Korea and United States

Jaeyoon Lee

2018-05-01

Full Text Available The main purpose of this study was to investigate the impact of perceived HR practices on affective commitment and turnover intention. This study explored which HR practices were relatively more important in predicting affective commitment and turnover intention. A total of 302 employees from the United States and 317 from South Korea completed the same questionnaires for assessing the aforementioned relationships. The results illustrated that among perceived HR practices, internal mobility had the most significant association with turnover intention in both the United States and South Korea. While internal mobility was a stronger predictor of affective commitment for the United States sample, training was the most important variable for predicting affective commitment in South Korea. The second purpose of the study was to examine whether individuals’ positive affect influences the relationship between perceived HR practices and affective commitment and turnover intention. In the United States, positive affect moderated the relationship between perceived HR practices and affective commitment and turnover intention such that the relationships were stronger for individuals reporting high positive affect relative to those reporting low positive affect. However, these relationships were not significant in South Korea. We discuss the implications of these results, study limitations, and practical suggestions for future research.

Relative Importance Assigned to Health Care Rationing Principles at the Bedside: Evidence From a Portuguese and Bulgarian Survey.

Pinho, Micaela Moreira; Pinto Borges, Ana

Activity was undertaken to develop a Prioritization Scoring Index for Portugal and Bulgaria that weights the importance given to ethical rationing principles that should guide decisions at the bedside. Data from two random samples of 355 Portuguese and 298 Bulgarian members of the public were collected from an online questionnaire. Questions asked about the level of importance given to specific issues related to patient's prioritization criteria. Responses were analyzed quantitatively with the SPSS. In the process of selecting the patient to treat, Portuguese and Bulgarian respondents seem unanimous in giving greater importance to (i) the treatment outcomes, (ii) the severity of illness, (iii) children, and (iv) patients' fragility. In general, Portuguese and Bulgarian respondents allocate more than 50% of the prioritization weight to equity considerations, approximately 35% to efficiency considerations, and 5% to lottery selection. Even so, Bulgarian respondents rate highly the equity and less the efficiency consideration than Portuguese respondents. Although the pursuit of efficiency seems to be valued by respondents, their major concern seems to be with the reduction of inequalities in health.

On the Relative Importance of Corporate Working Capital Determinants: Findings from the EU Countries

Directory of Open Access Journals (Sweden)

Julia Koralun-Bereźnicka

2014-12-01

Full Text Available The corporate finance literature traditionally abounds in both theoretical discussion and empirical research concerning financing and long-term investment decisions. Managing short-term resources appears to be a much less remarkable issue, despite this resource’s significant share of a firm’s balance sheet and the time and effort required to manage the current assets and liabilities. This article provides insights into the relative importance of the selected working capital determinants from the European Union perspective. The determinants considered in the study include both external and internal factors, specifically the country in which a company operates, its industrial classification and the firm size. Using more than 10,000 aggregated observations from a sample of firms from 13 industries, 9 countries and 3 group sizes, covering the period 2000-2009, the findings provide evidence that corporate working capital is most affected by country-specific factors, followed by industrial factors and firm size.
