Global conservation priorities have often been identified based on the combination of species richness and threat information. With the development of the field of systematic conservation planning, more attention has been given to conservation costs. This leads to prioritizing developing countries, where costs are generally low and biodiversity is high. But many of these countries have poor governance, which may result in ineffective conservation or in larger costs than initially expected. We explore how the consideration of governance affects the selection of global conservation priorities for the world's mammals in a complementarity-based conservation prioritization. We use data on Control of Corruption (Worldwide Governance Indicators project) as an indicator of governance effectiveness, and gross domestic product per capita as an indicator of cost. We show that, while core areas with high levels of endemism are always selected as important regardless of governance and cost values, there are clear regional differences in selected sites when biodiversity, cost or governance are taken into account separately. Overall, the analysis supports the concentration of conservation efforts in most of the regions generally considered of high priority, but stresses the need for different conservation approaches in different continents owing to spatial patterns of governance and economic development.

Soil-to-plant concentration factors for radiological assessments

International Nuclear Information System (INIS)

Ng, Y.C.; Thompson, S.E.; Colsher, C.S.

1982-09-01

This report presents the results of a literature review to derive soil-to-plant concentration factors to predict the concentration of a radionuclide in plants from that in soil. The concentration factor, B/sub v/ is defined as the ratio of the concentration of a nuclide in the edible plant part to that in dry soil. CR (the concentration ratio) is similarly defined to denote the concentration factor for dry feed consumed by livestock. B/sub v/ and CR values are used to assess the dose from radionuclides deposited onto soil and transferred into crop plants via roots. Approaches for deriving B/sub v/ and CR values are described, and values for food and feed are tabulated for individual elements. The sources of uncertainty are described, and the factors that contribute to the inherent variability of the B/sub v/ and CR values are discussed. Summary tables of elemental B/sub v/ and CR values and statistical parameters that characterize their distributions provide a basis for a systematic updating of many of the B/sub v/ values in Regulatory Guide 1.109. They also provide a basis for selecting B/sub v/ and CR values for other applications that involve the use of equilibrium models to predict the concentration of radionuclides in plants from that in soil

A hypothesis: factor VII governs clot formation, tissue repair and apoptosis.

Science.gov (United States)

Coleman, Lewis S

2007-01-01

A hypothesis: thrombin is a "Universal Enzyme of Energy Transduction" that employs ATP energy in flowing blood to activate biochemical reactions and cell effects in both hemostasis and tissue repair. All cells possess PAR-1 (thrombin) receptors and are affected by thrombin elevations, and thrombin effects on individual cell types are determined by their unique complement of PAR-1 receptors. Disruption of the vascular endothelium (VE) activates a tissue repair mechanism (TRM) consisting of the VE, tissue factor (TF), and circulating Factors VII, IX and X that governs localized thrombin elevations to activate clot formation and cellular effects that repair tissue damage. The culmination of the repair process occurs with the restoration of the VE followed by declines in thrombin production that causes Apoptosis ("programmed cell death") in wound-healing fibroblasts, which functions as a mechanism to draw wound edges together. The location and magnitude of TRM activity governs the location and magnitude of Factor VIII activity and clot formation, but the large size of Factor VIII prevents it from penetrating the clot formed by its activity, so that its effects are self-limiting. Factors VII, IX and X function primarily as tissue repair enzymes, while Factor VIII and Factor XIII are the only serine protease enzymes in the "Coagulation Cascade" that are exclusively associated with hemostasis.

On the application of concentration factor

International Nuclear Information System (INIS)

Shimizu, Makoto

1981-01-01

Concentration factor is used to estimate internal dose through consumption of fish and shellfish. The amount of nuclide intake is estimated as ''radioactivity in ambient water x concentration factor x consumption of fish and shellfish''. These parameters involved are usually treated as constants but these actually are variables. Here the significance of their variation on dose assessment is examined. Concentration factors are varied according to various environmental as well as biological factors. For example, Hg, Cs, and As in the muscle of Galeus nipponensis increase as total length increases and, on the contrary, Cu, Zn, Fe and Co show negative correlation with total length. We should examine these cases and determine what value should be used in dose assessment. More important is to build up models to interprete these phenomena totally. Significance of variation in ambient radioactivity was examined by a simulation of nuclide accumulation in biota exposed to intermittent release and compared with that to continuous release. Variations either within a day or within a year were not shown to have much effect. On the variations in sea food consumption, several examples were given. Problem to be solved is how to consider these variations on assessing internal dose due to fish consumption. In conclusion it is necessary to get more of such kind of informations on the variations of parameters. And also we should determine the precision of each parameter in the whole picture of dose assessment. (author)

Stress Concentration Factor and Stress Intensity Factor with U-notch and Crack in the Beam

Energy Technology Data Exchange (ETDEWEB)

Seo, Bo Seong; Lee, Kwang Ho [Kyungpook National Univ., Daegu (Korea, Republic of)

2016-05-15

The stress concentration factors and stress intensity factors for a simple beam and a cantilever are analyzed by using finite element method and photoelasticity. Using the analyzed results, the estimated graphs on stress concentration factors and stress intensity factors are obtained. To analyze stress concentration factors of notch, the dimensionless notch length H(height of specimen)/h=1.1-2 and dimensionless gap space r(radius at the notch tip)/h=0.1~0.5 are used, where h=H-c and c is the notch length. As the notch gap length increases and the gap decreases, the stress concentration factors increase. Stress concentration factors of a simple beam are greater than those of a cantilever beam. However, actually, the maximum stress values under a load, a notch length and a gap occur more greatly in the cantilever beam than in the simple beam. To analyze stress intensity factors, the normalized crack length α(crack length)/H=0.2~0.5 is used. As the length of the crack increases, the normalized stress intensity factors increase. The stress intensity factors under a constant load and a crack length occur more greatly in the cantilever beam than in the simple beam.

Rn-222(radon) air concentration depends on several factors. Some of the factors are source related and other factors are environmentally related. Because high levels of radon concentrations in air have potential health effects, it is important to study the impact of the various factors affecting radon air concentration. Laboratory scale investigations of the various factors affecting radon air concentration were carried out under controlled conditions that allow variation of the various variables

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

International Nuclear Information System (INIS)

Meinhold, A.F.; Hamilton, L.D.

1991-01-01

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

Recent research on the effects of dam and sluice construction on the water environment has attracted extensive attention from academia and governments alike. Because the operation of sluices greatly alters environmental factors such as water flow and sediment load, the water quality in sluice-controlled river reaches (SCRRs) undergoes complex changes compared with those in normal reaches. This work used river reaches near the Huaidian Sluice in Shaying River of China as a case study to analyse the effects of sluice operation on water quality evolution in SCRRs. The most influential factors affecting the rate of change in chemical oxygen demand (COD) concentration in SCRRs were identified through water quality monitoring experiments performed under various modes of sluice operation and by applying a statistical method 'partial correlation analysis'. Then, a hydrodynamic model incorporating sluice operation and a water quality transport and transform model incorporating the release of endogenous loads were developed. Using these two models, the processes of temporal and spatial change of COD concentrations in the SCRRs were simulated under various scenarios designed to represent the dominant factors of influence. Finally, the simulation results were used to develop empirical relationships between the rate of change in COD concentrations and the dominant factors of influence. The results reveal that three factors, i.e., water inflow concentration, gate opening size, and gate opening number, are the dominant factors of influence, and there are logarithmic relationships between the rate of change in COD concentration in the SCRRs and these factors.

An investigation of factors influencing indoor radon concentrations

International Nuclear Information System (INIS)

Majborn, B.; Soerensen, A.; Nielsen, S.P.; Boetter-Jensen, L.

1988-05-01

Variations in indoor radon concentrations and some influencing factors have been studied during a two-year period (1986-1987) in 16 almost identical single-family houses.The annual average radon concentration in the houses varied from about 50 to about 400 Bq/m 3 . Variations in soil characteristics and radon concentration in soil gas could not be directly related to the variations of the average indoor radon concentrations. Most of the houses showed a ''normal'' seasonal variation of the radon concentration with a maximum in the winter and minimum in the summer. A deviating seasonal variation was found in three of the houses. Hourly data obtained in one unoccupied house during a period of 2-1/2 months showed no or only weak correlations between the indoor radon concentration and meteorological factors. However, for most of the houses, the seasonal variation of the indoor radon concentration was well correlated with the average indoor-outdoor temperature difference on a 2-month basis. It was demonstrated that the radon concentration can be strongly reduced in the Risoe houses if a district-heating duct, which is connected to all the houses, is ventilated, so that a slightly lowered pressure is maintained in the duct. 5 taps., 24 ill.

Anon.

1974-01-01

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

Full Text Available Knowledge governance is a relatively new discipline in Malaysia with very little research work performed so far. As Malaysian government is actively involved in the implementation of Economic Transformation Program (ETP, Government Transformation Program (GTP and Urban Trans-formation Program (UTP, Small and Medium Enterprises (SMEs need to react to the government move by transforming their conventional knowledge management practices to knowledge govern-ance. As of today, there has been very limited study conducted in Malaysia on the extent of the company acceptance of such governance. This research was therefore conducted to measure the SME users' acceptance and identify the pros and cons of knowledge governance. With these findings, recommendations were given to policy makers and industries to increase the company's knowledge governance acceptance. Questionnaire was used for data collection. Systematic random sampling methods was used to select respondents. The questionnaire was developed and adapted based on knowledge management and IT governance frameworks. In this model, the dependent variable was company's intention to adopt knowledge governance. Independent variables included knowledge application needs, knowledge architecture, knowledge infrastructure, knowledge investment and knowledge principles.

Concentration factors and aggregated transfer factors in selected bio-indicators from Sweden[Radioecology

Previously most common has been to use lichens and mosses in the terrestrial environment and mussels and algae in the marine environment. Several plants are promising and less commonly used such as ferns (e.g. Bracken, Pteridium aquilinum) and the fresh water plant, Water horsetail (Equisetum fluviatile). These show high uptake of radiocaesium but also accumulate plutonium and americium. Even if the uptake of transuranic elements is low, this behaviour is rather unique for plants. On bases of available data we have calculated concentration factors Cf and aggregated transfer factors, ATF according to their definitions i.e. Bq kg{sup -1} (biota)/Bq kg{sup -1}(water) and Bq kg{sup -1} (biota)/Bq m{sup -2} respectively. For earlier samples the water concentrations can only roughly be estimated while deposition data are rather well known. For fresh water samples it is a little awkward to use concentration factors since the uptake generally is not from water. Therefore a kind of Aggregated Transfer Factor has also been calculated on basis of using the same areal deposition in sediments as on land. We have used dry weight concentrations for biota. Data are presented for samples of various bio-medicator organisms. (LN)

Interactive governance

DEFF Research Database (Denmark)

Sørensen, Eva; Torfing, Jacob; Peters, B. Guy

Governance has become one of the most commonly used concepts in contemporary political science. It is, however, often used to mean a variety of different things. This book helps to clarify this conceptual muddle by concentrating on one variety of governance-interactive governance. The authors argue...... that although the state may remain important for many aspects of governing, interactions between state and society represent an important, and perhaps increasingly important, dimension of governance. These interactions may be with social actors such as networks, with market actors or with other governments......, but all these forms represent means of governing involving mixtures of state action with the actions of other entities.This book explores thoroughly this meaning of governance, and links it to broader questions of governance. In the process of explicating this dimension of governance the authors also...

As with many countries, the Korea government has made a variety of efforts to meet the precautionary principle under the London Convention and Protocol acceded in 1994 and 2009. However, new strategies for the suitable marine dumping of waste materials have since been developed. In this study, the distribution and contamination of heavy metals including Al, Fe, Mn, Li, Co, Cr, Ni, Cu, Zn, As, Cd, Pb and Hg in bottom sediments were analyzed and compared to various criteria in order to evaluate the effectiveness of the management of the East Sea-Jung (ES-Jung) dumping site by the Korea government. The results indicate that the average metal concentrations were significantly lower than Effects Range Low (ERL) values, and generally similar to or lower than the Threshold Effect Levels (TEL) from the Sediment Quality Guidelinces (SQGs). According to analyses of various metal contamination indexes (Enrichment Factor: EF, Pollution Load Index: PLI and the Index of Geoaccumulation: Igeo), most areas were found to be uncontaminated by heavy metals with the exception of several moderately contaminated stations (ESJ 33, 54, 64 and ESJR 20). Heavy metal concentrations in areas grouped as G1, G2, DMDA, N-Ref and S-Ref which showed similar characteristics between 2007-2013 and 2014, were compared. Unexpectedly, most concentrations in the northern reference area (N-Ref) were much higher than those in the actual dumping areas (G1 and G2), may be due to the influences from nearby cities to the west of the ES-Jung site, rather than from the dumping site itself. Additionally, heavy metal concentrations in the dredged material dumping area (DMDA) were found to be low although they have slightly increased over time and those in the southern reference area (S-Ref) were found to have gradually decreased with year. The concentrations of most metals in the East Sea-Jung dumping site were similar to or less than those in the Earth's crust and approximately the same as those in continental

2016-10-01

Full Text Available Innovative ways to manage the urban water cycle are required to deal with an ageing drinking and waste water infrastructure and new societal imperatives. This paper examines the influence of water governance in enabling transformations and technological innovation uptake in urban water management. A governance assessment framework is developed and applied in three case-studies, examining different scales and types of innovations used to tackle challenges in European urban water management. The methodology combines documentary analysis and interviews to reconstruct historical storylines of the shift in the water governance of urban water management for each site. The research provides detailed empirical observations on the factors conducive to innovation uptake at the local level. Critical governance factors such as commitment to compromise, the necessity to build political support, and the role of “entrepreneurs” and coalitions are highlighted. The paper also explores the role of discursive strategies and partnership design, as well as that of regulative, economic and communicative instruments, in creating barriers and opportunities to initiate and secure change. A number of recommendations targeted at innovators and water managers are presented in the conclusion.

Full Text Available 1024x768 Reformation in Indonesian government offices leads to many substantial changes, and demands improved job performances while arguably loading employees with more work. This research aims to understand factors that potentially influence job performance in Indonesian government offices that carries on such reformation. Using adapted scales from previous studies, this research investigates the role of workload, responsibility for others (level of responsibility to care for other people and need for achievement on employee’s performance.  A survey to all full-time workers in an Indonesian government office is conducted. Contrary to expectation, workload does not influence employee’s performance. Instead, regression analysis demonstrates that, employee’s need for achievement and responsibility for others are significant factors affecting individual performance. These results are important because they highlight the significance of need for achievement for the success of reformation in this office, and by extension for reformation in Indonesia. The results are also interesting because this is the first study that points out to the role of responsibility for others in influencing individual performance in Indonesia which is characterized by collectivistic culture.

Factors that influence an elemental depth concentration profile

International Nuclear Information System (INIS)

McHugh, J.A.

1975-01-01

The use of secondary ion mass spectrometry in concentration profiling is discussed. Two classes of factors that influence an elemental concentration profile are instrumental effects and ion-matrix effects. Instrumental factors that must be considered are: (1) uniformity of the primary ion current density, (2) constancy of the primary ion current, (3) redeposition, (4) memory, (5) primary ion beam tailing and the nonfocused component, (6) chemical purity of the primary ion beam, and (7) residual gas impurities. Factors which can be classified as ion matrix effects are: (1) the mean escape depth of secondary ions, (2) recoil implantation, (3) molecular ion interferences, (4) primary ion beam induced diffusion of matrix species, (5) nonuniform sputter removal of matrix layers, and (6) implanted primary ion chemical and lattice damage effects

Vasopressin plays an important role in maintaining volume homeostasis. However, recent studies suggest that vasopressin also may play a detrimental role in the progression of chronic kidney disease. It therefore is of interest to identify factors that influence vasopressin concentration, particularly modifiable ones. Cross-sectional analyses. Data used are from participants in a large general-population cohort study (Prevention of Renal and Vascular Endstage Disease [PREVEND]). Patients with a missing copeptin value (n=888), nonfasting blood sample (n=495), missing or assumed incorrect 24-hour urine collection (n=388), or heart failure (n=20) were excluded, leaving 6,801 participants for analysis. Identification of lifestyle- and diet-related factors that are associated with copeptin concentration. Copeptin concentration as surrogate for vasopressin. Copeptin was measured by an immunoluminometric assay as a surrogate for vasopressin. Associations were assessed in uni- and multivariable linear regression analyses. Median copeptin concentration was 4.7 (IQR, 2.9-7.6) pmol/L. When copeptin was studied as a dependent variable, the final stepwise backward model revealed associations with higher copeptin concentrations for lower 24-hour urine volume (P firm conclusions on cause-effect relationships. Important lifestyle- and diet-related factors associated with copeptin concentration are current smoking, alcohol use, protein and potassium intake, and particularly fluid and sodium intake. These data form a rationale to investigate whether intervening on these factors results in a lower vasopressin concentration with concomitant beneficial renal effects.

The study was conducted for the companies listed on BSE, in the first category. The financial companies and the credit institutions were excluded from the sample. The final sample included 15 companies. Return on Assets, Return on Equity and Return on Sales were used for measuring the performance of the firm. The corporate governance was measured with three variables: total numbers of board members, the percentage of independent members on the board and CEO duality. The ownership concentration was measured with the fraction of shares held by the largest top three shareholders having over 10% and Herfindal index. Econometric tools like multiple linear regressions were used for analysis. The results of the study suggest that there is a positive significant link between firm performance and proportion of independent members of the board.

Full Text Available Since the financial crisis in year 1997, banks in Malaysia had undergone various issues and transformations, including stricter regulation on merger and acquisitions and greater enforcement of corporate governance. Besides that, the institutions had also gone through the transformation in terms of the risk assessment practice due to the stricter rulings under Basel II regulations. Taking into account of these changes, this study empirically examines the effects of corporate governance, risk and capital on the performance of banks in Malaysia. Based on 132 firm-year samples for the period of 2004-2009, study indicates a significant and negative relationship between bank risks and performance. It further reveals that the risk weighted capital (RRWC improves bank performance. However none of the corporate governance variables have any associations with banks performance. The detail explanations of the findings along with the suggestions for future research are provided in the full text of the reports

Variance of radon concentration in dwelling atmosphere is analysed with regard to geogenic and anthropogenic influencing factors. Analysis includes review of 81 national and regional indoor radon surveys with varying sampling pattern, sample size and duration of measurements and detailed consideration of two regional surveys (Sverdlovsk oblast, Russia and Niška Banja, Serbia). The analysis of the geometric standard deviation revealed that main factors influencing the dispersion of indoor radon concentration over the territory are as follows: area of territory, sample size, characteristics of measurements technique, the radon geogenic potential, building construction characteristics and living habits. As shown for Sverdlovsk oblast and Niška Banja town the dispersion as quantified by GSD is reduced by restricting to certain levels of control factors. Application of the developed approach to characterization of the world population radon exposure is discussed. - Highlights: • Influence of lithosphere and anthroposphere on variance of indoor radon is found. • Level-by-level analysis reduces GSD by a factor of 1.9. • Worldwide GSD is underestimated.

Quality control in the development of coagulation factor concentrates.

Snape, T J

1987-01-01

Limitation of process change is a major factor contributing to assurance of quality in pharmaceutical manufacturing. This is particularly true in the manufacture of coagulation factor concentrates, for which presumptive testing for poorly defined product characteristics is an integral feature of finished product quality control. The development of new or modified preparations requires that this comfortable position be abandoned, and that the effect on finished product characteristics of changes to individual process steps (and components) be assessed. The degree of confidence in the safety and efficacy of the new product will be determined by, amongst other things, the complexity of the process alteration and the extent to which the results of finished product tests can be considered predictive. The introduction of a heat-treatment step for inactivation of potential viral contaminants in coagulation factor concentrates presents a significant challenge in both respects, quite independent of any consideration of assessment of the effectiveness of the viral inactivation step. These interactions are illustrated by some of the problems encountered with terminal dry heat-treatment (72 h. at 80 degrees C) of factor VIII and prothrombin complex concentrates manufactured by the Blood Products Laboratory.

Significant factors for enabling knowledge sharing between government agencies within South Africa

Directory of Open Access Journals (Sweden)

Avain Mannie

2013-10-01

Objectives: This study aimed to validate the significant factors that influence the effectiveness of KM between government agencies in South Africa. The commonly identified pillars of KM in the extant literature served as a primary framework in establishing these factors. Method: Data were gathered using an electronic survey made available to different national government agencies within the security cluster. Responses were analysed using structural equation modelling. Main findings: Existing literature highlighted organisational culture, learning organisation, collaboration, subject matter experts and trust as being determinants for knowledge management. The first two were identified as the most significant factors for knowledge sharing to succeed. Conclusion: Whilst there is universal consent as to the strategic importance of KM, actionable implementation of knowledge sharing initiatives appears to be lacking. This study emphasised the fact that leaders must instil a knowledge sharing culture either through employee performance contracts or methods such as the balanced score card. The study also showed that it is imperative for leaders to acknowledge that KM is a multi-faceted discipline that offers strategic advantages. Leaders of developing countries should note that they are on a developmental journey. This requires their organisations to be learning organisations, which necessitates a change in the organisational culture and knowledge interventions through their academies of learning.

Corporate governance, cultural factors and voluntary disclosure: Evidence from selected companies in Bangladesh

Directory of Open Access Journals (Sweden)

M. Akhtaruddin

2012-01-01

Full Text Available This research aims to test empirically the relationship between corporate governance, cultural factors and voluntary disclosure by the listed companies in Bangladesh. The corporate governance factors examined are proportion of independent non-executive directors (INDs, board leadership structure, management ownership, board size and audit committee size. The extent of voluntary disclosure level is measured using 68 items of information. Data are taken from annual reports of the listed companies in Bangladesh. The result shows a positive association between board size, board leadership structure, audit committee size and voluntary disclosure. However, no evidence is found to support the contention that independent directors are associated with increased disclosure, consistent with previous studies. Higher education of the CEO and CFO is positively related to the level of voluntary disclosure. The result also indicates that the extent of voluntary disclosures is negatively associated with a higher management ownership.

Factor VII concentrates are used in patients with congenital or acquired factor VII deficiency or treatment of hemophilia patients with inhibitors. In this research, immunoaffinity chromatography was used to purify factor VII from prothrombin complex (Prothrombin- Proconvertin-Stuart Factor-Antihemophilic Factor B or PPSB) which contains coagulation factors II, VII, IX and X. The aim of this study was to improve purity, safety and tolerability as a highly purified factor VII concentrate. PPSB was prepared using DEAE-Sephadex and was used as the starting material for purification of coagulation factor VII. Prothrombin complex was treated by solvent/detergent at 24°C for 6 h with constant stirring. The mixture of PPSB in the PBS buffer was filtered and then chromatographed using CNBr-activated Sepharose 4B coupled with specific antibody. Factors II, IX, VII, X and VIIa were assayed on the fractions. Fractions of 48-50 were pooled and lyophilized as a factor VII concentrate. Agarose gel electrophoresis was performed and Tween 80 was measured in the factor VII concentrate. Specific activity of factor VII concentrate increased from 0.16 to 55.6 with a purificationfold of 347.5 and the amount of activated factor VII (FVIIa) was found higher than PPSB (4.4-fold). RESULTS of electrophoresis on agarose gel indicated higher purity of Factor VII compared to PPSB; these finding revealed that factor VII migrated as alpha-2 proteins. In order to improve viral safety, solvent-detergent treatment was applied prior to further purification and nearly complete elimination of tween 80 (2 μg/ml). It was concluded that immuonoaffinity chromatography using CNBr-activated Sepharose 4B can be a suitable choice for large-scale production of factor VII concentrate with higher purity, safety and activated factor VII.

Current use of factor concentrates in pediatric cardiac anesthesia.

Guzzetta, Nina A; Williams, Glyn D

2017-07-01

Excessive bleeding following pediatric cardiopulmonary bypass is associated with increased morbidity and mortality, both from the effects of hemorrhage and the therapies employed to achieve hemostasis. Neonates and infants are especially at risk because their coagulation systems are immature, surgeries are often complex, and cardiopulmonary bypass technologies are inappropriately matched to patient size and physiology. Consequently, these young children receive substantial amounts of adult-derived blood products to restore adequate hemostasis. Adult and pediatric data demonstrate associations between blood product transfusions and adverse patient outcomes. Thus, efforts to limit bleeding after pediatric cardiopulmonary bypass and minimize allogeneic blood product exposure are warranted. The off-label use of factor concentrates, such as fibrinogen concentrate, recombinant activated factor VII, and prothrombin complex concentrates, is increasing as these hemostatic agents appear to offer several advantages over conventional blood products. However, recognizing that these agents have the potential for both benefit and harm, well-designed studies are needed to enhance our knowledge and to determine the optimal use of these agents. In this review, our primary objective was to examine the evidence regarding the use of factor concentrates to treat bleeding after pediatric CPB and identify where further research is required. PubMed, MEDLINE/OVID, The Cochrane Library and the Cochrane Central Register of Controlled Trials (CENTRAL) were systematically searched to identify existing studies. © 2017 John Wiley & Sons Ltd.

Measurements of plasma homovanillic acid (pHVA) concentrations appear to be a valid research strategy in psychiatric disorders in which a central dopamine (DA) abnormality has been implicated. This study provides guidance about the control of some of the exogenous factors affecting pHVA concentrations. Fasting for 14 hours eliminates the dietary effects on pHVA in healthy human subjects. Changing position, walking for 30 minutes, or smoking two cigarettes has no effect on pHVA concentrations.

Factor Configurations with Governance as Conditions for Low HIV/AIDS Prevalence in HIV/AIDS Recipient Countries: Fuzzy-set Analysis.

Science.gov (United States)

Lee, Hwa-Young; Yang, Bong-Min; Kang, Minah

2015-11-01

This paper aims to investigate whether good governance of a recipient country is a necessary condition and what combinations of factors including governance factor are sufficient for low prevalence of HIV/AIDS in HIV/AIDS aid recipient countries during the period of 2002-2010. For this, Fuzzy-set Qualitative Comparative Analysis (QCA) was used. Nine potential attributes for a causal configuration for low HIV/AIDS prevalence were identified through a review of previous studies. For each factor, full membership, full non-membership, and crossover point were specified using both author's knowledge and statistical information of the variables. Calibration and conversion to a fuzzy-set score were conducted using Fs/QCA 2.0 and probabilistic tests for necessary and sufficiency were performed by STATA 11. The result suggested that governance is the necessary condition for low prevalence of HIV/AIDS in a recipient country. From sufficiency test, two pathways were resulted. The low level of governance can lead to low level of HIV/AIDS prevalence when it is combined with other favorable factors, especially, low economic inequality, high economic development and high health expenditure. However, strengthening governance is a more practical measure to keep low prevalence of HIV/AIDS because it is hard to achieve both economic development and economic quality. This study highlights that a comprehensive policy measure is the key for achieving low prevalence of HIV/AIDS in recipient country.

Copper-containing contraceptive devices may deposit copper ions in the endometrium, resulting in implantation failure. The deposition of copper ions in many organs has been reported in patients with untreated Wilson's disease. Since these patients sometimes exhibit subfertility and/or early pregnancy loss, copper ions were also considered to accumulate in the uterine endometrium. Wilson's disease patients treated with zinc successfully delivered babies because zinc interfered with the absorption of copper from the gastrointestinal tract. These findings led to the hypothesis that infertile patients with high serum copper concentrations may have implantation failure due to the excess accumulation of copper ions. The relationship between implantation (pregnancy) rates and serum copper concentrations has not yet been examined. The Japanese government recently stated that actual copper intake was higher among Japanese than needed. Therefore, the aim of the present study was to investigate whether serum copper concentrations are related to the implantation (pregnancy) rates of human embryos in vivo. We included 269 patients (age copper, and zinc concentrations were measured 16 days after the first date of progesterone replacement. We compared 96 women who were pregnant without miscarriage at 10 weeks of gestation (group P) and 173 women who were not pregnant (group NP). No significant differences were observed in age or BMI between the groups. Copper concentrations were significantly higher in group NP (average 193.2 μg/dL) than in group P (average 178.1 μg/dL). According to the area under the curve (AUC) on the receiver operating characteristic curve for the prediction of clinical pregnancy rates, the Cu/Zn ratio (AUC 0.64, 95% CI 0.54-0.71) was a better predictor than copper or zinc. When we set the cut-off as 1.59/1.60 for the Cu/Zn ratio, sensitivity, specificity, the positive predictive value, and negative predictive value were 0.98, 0.29, 0.71, and 0

Governance of a country may have widespread effects on the health of its population, yet little is known about the effect of governance on child mortality in a country that is undergoing urbanization, economic development, and disease control. We obtained indicators of six dimensions of governance (perceptions of voice and accountability, political stability and absence of violence, government effectiveness, regulatory quality, rule of law, and control of corruption) and national under-5 mortality rates for 149 countries between 1996 and 2010. We applied a semi-parametric generalized additive mixed model to examine associations after controlling for the effects of development factors (urbanization level and economy), disease control factors (hygienic conditions and vaccination rates), health expenditures, air quality, and time. Governance, development, and disease control showed clear inverse relations with the under-5 mortality rate (pcountry's need for better governance is as important as improvements in development and disease control. © The Author 2014.

Atherosclerosis begins in childhood. At present among numerous risk factors of atherosclerosis the role of hiperhomocysteinemia in development of cardiovascular heart disease is taken under consideration. Atherogenic effect of homocystein is related to its cytotoxin action, conducting to endothelial dysfunction and damage. It is correlated with increase of the lipid levels in the blood serum and change of expression of the soluble forms of adhesion molecules. The aim of this study was to estimate relations between the homocystein serum concentration, expression of the selected adhesion molecules and the lipid levels in the blood serum in children with atherosclerosis risk factors. The group consisted of 670 children, 76 of them had atherosclerosis risk factors. In further examination 48 children have taken a part, whose parents were agreed for theirs participation in the program. The comparative group composed of 25 children without the risk factors. We determined total cholesterol (TC), triglycerides (TG), LDL cholesterol fraction (LDL-C), HDL cholesterol fraction (HDL-C), serum homocysteine concentration (Hcy), the expression of the soluble forms of adhesion molecules (sCAM): sP-selectin and sVCAM-1 (vascular cell adhesion molecule-1). Obesity, hypertension and lipid disorders in the shape of higher concentration of TC, LDL-C, TG and lower HDL-C were the most frequent risk factors in the investigated children. No significant differences in serum homocysteine concentration were observed between the investigated groups. However, its concentration was significantly higher in children with two atherosclerosis risk factors. No significant differences in expression of s-VCAM-1 were observed in the investigated groups, concentration of sP-selectin was significantly higher in children with atherosclerosis risk factors (phomocysteine and chosen adhesion molecules in children with atherosclerosis risk factors might potentially constitute the marker of early

Full Text Available The objective of this study was examining the factors affecting the government procurement fraud. Based on the fraud triangle and the theory of planned behavior, this study proposed seven hypothesis, those are tested by regression analysis. This study used primary data gathered by surveys to members of The Boards of the Republic Indonesia- Financial Auditors, who act as external auditors for the Government. They were asked to assess factors influencing the government procurement of goods and services fraud. There were 297 auditors of the Boards that participated in this survey. The result showed that the procurement frauds were influenced by the lack of procurement committee quality, the weakness of procurement control, and the intentions to engage fraud. The intentions to engage fraud were significantly influenced by the attitude toward fraud, subjective norms, and the perceived behavioral control. Furthermore, other elements of fraud triangle, the financial pressure, did not influence to the procurement fraud.

Regulatory factors governing adenosine-to-inosine (A-to-I) RNA editing.

Science.gov (United States)

Hong, HuiQi; Lin, Jaymie Siqi; Chen, Leilei

2015-03-31

Adenosine-to-inosine (A-to-I) RNA editing, the most prevalent mode of transcript modification in higher eukaryotes, is catalysed by the adenosine deaminases acting on RNA (ADARs). A-to-I editing imposes an additional layer of gene regulation as it dictates various aspects of RNA metabolism, including RNA folding, processing, localization and degradation. Furthermore, editing events in exonic regions contribute to proteome diversity as translational machinery decodes inosine as guanosine. Although it has been demonstrated that dysregulated A-to-I editing contributes to various diseases, the precise regulatory mechanisms governing this critical cellular process have yet to be fully elucidated. However, integration of previous studies revealed that regulation of A-to-I editing is multifaceted, weaving an intricate network of auto- and transregulations, including the involvement of virus-originated factors like adenovirus-associated RNA. Taken together, it is apparent that tipping of any regulatory components will have profound effects on A-to-I editing, which in turn contributes to both normal and aberrant physiological conditions. A complete understanding of this intricate regulatory network may ultimately be translated into new therapeutic strategies against diseases driven by perturbed RNA editing events. Herein, we review the current state of knowledge on the regulatory mechanisms governing A-to-I editing and propose the role of other co-factors that may be involved in this complex regulatory process.

Full Text Available There were only a few government institutions in Indonesia capable of preparing good accountability reports. Based on the survey conducted in the Special District of Yogyakarta, the study aimed to empirically examine the influencing factors in the development of the measure-ment system of performance, performance accountability and the use of performance informa-tion. Additionally, it also tried to interpret and to explain empirical evidence in the perspective of the institutional theory. The institutional theory was used to find out the extent to which the development of the measurement system of the performance, the performance accountability and the use of the performance information was influenced because of the presence of coercive, mimetic and normative isomorphism phenomena. The study used mixed methods that combined quantitative and qualitative study approaches simultaneously and a sequential explanatory strategy. It used Partial Least Square (PLS analysis to test the hypotheses. It gave evidence that training, incentives and authority in decision making had significant impacts on the development of the measurement of the performance, the performance accountability and the use of the performance information. It contributed to the understanding of the influencing factors of the development of the measurement system of the performance, the performance accountability and the use of the performance information in order to improve the measurement system of the performance of government institutions.

An investigation for identification of factors governing F and P phenomenon

1992-01-01

A series of experiments were carried out in divided electrolytic cells in an attempt to identify factors governing the occurence of Fleischmann and Pons (F and P) phenomenon. Despite wide variation in operating parameters (cathode characteristics, type and concentration of electrolyte) and perturbation of deuterated cathodes and sharp change in their temperatures, experiments yielded no evidence of the phenomenon even though high loading (sometimes upto D/Pd ∼2) could be achieved repeatedely. However, large excess heat liberation, not accountable by probable physicochemical processes, was observed following perturbation of the state of equilibrium of a deuterated cathode (having a portion of it free of scale and bright in appearance) by air. Instances of anomalies in tritium distribution between gas and liquid phase resulting from such perturbation were also noticed. These observations, when analysed in global perspective, clearly indicate the essentiality of oxygen and scale free surface for occurrence of the phenomenon. Study of desorption dynamics and related parameters revealed that the overall effect of oxygen is to enhance the escaping tendency of deuterium from Pd lattice and that the phenomenon is in someway related to desorption. Significant increase in tritium activity in gas phase observed following repeated perturbation of deuterated cathode by induced pulsed magnetic field is suggestive of a possible mechanism in which strong electron affinity of oxygen is of paramount importance.

In minipigs little is known about the concentration of growth factors in plasma, despite their major role in several patho-physiological processes such as healing of fractures. This prompted us to study the concentration of platelets and selected growth factors in plasma and platelet-rich plasma (PRP) preparation of sixteen Goettingen minipigs. Platelet concentrations increased significantly in PRP in comparison to native blood plasma. Generally, significant increase in the concentration of all growth factors tested was observed in the PRP in comparison to the corresponding plasma or serum. Five of the plasma samples examined contained detectable levels of bone morphogenic protein 2 (BMP-2) whereas eleven of the plasma or serum samples contained minimal amounts of vascular endothelial growth factor (VEGF) and platelet-derived growth factor (PDGF-bb) respectively. On the other hand variable concentrations of bone morphogenic protein 7 (BMP-7) and transforming growth factor β1 (TGF-β1) were measured in all plasma samples. In contrast, all PRP samples contained significantly increased amounts of growth factors. The level of BMP-2, BMP-7, TGF-β1, VEGF and PDGF-bb increased by 17.6, 1.5, 7.1, 7.2 and 103.3 fold, in comparison to the corresponding non-enriched preparations. Moreover significant positive correlations were found between platelet count and the concentrations of BMP-2 (r=0.62, pplatelet-rich plasma of minipigs which might thus serve as a source of autologous growth factors.

2015-01-01

The concentration of metallothionein (MT), a low-molecular-weight protein, is regulated by many factors, primarily metals (zinc, cadmium, copper), cytokines, glucocorticoides and free radicals. These factors are determined by such aspects of human biology as gender, pregnancy and age, as well as by environmental factors including the use of oral contraceptives and cigarette smoking, all which may affect MT levels in the body. The aim of this study was to investigate the influence of these biological and environmental factors on MT concentrations in erythrocyte lysate and in plasma. MT concentrations were determined by a two-step direct enzyme-linked immunosorbent assay. Evaluation of exposure to cigarette smoking was performed by checking cotinine levels in the plasma of subjects. The studies showed higher MT concentrations in both the erythrocyte lysate and plasma of women when compared to men. Furthermore, pregnancy causes an increase of MT concentration in plasma, while oral contraceptives cause an elevated concentration of MT in erythrocyte lysate. Age impacts plasma MT concentrations in men, whereas it does not affect concentrations of MT in erythrocyte lysate. Copyright © 2014 Elsevier GmbH. All rights reserved.

Full Text Available Abstract Much literature on electronic government services research could be found on adoptability issues from government and service providers point of view. Many studies have looked into adoptability factors from user perspectives and majority captured adoptability perspectives of frequent Internet users the ones who use Internet applications for more than 10 hours a week. On the contrary the perspectives of majority of Pakistani users which use Internet applications for less than 10 hours per week are never inquired. This paper tries to fill this gap by looking into electronic government adoptability perspectives and expectations of such Internet users of Pakistan which are much greater in numbers than others. An amended UTAUT model with all its moderators is used in this study and the results demonstrate that performance level ease of effort and social influence strongly effect behavioral intention of users in using electronic government services in Pakistan. The individuals behavioral intention along with presence of appropriate facilitating conditions triggers use behavior of users. The results show that only gender moderates majority of UTAUT relationships and accordingly a modified UTAUT model is presented. The paper provides certain insights for people making policies and academicians for performing further research while it stresses for service proliferation with special attention towards female population.

Characteristics of the Corporate Bank Governance System in Bosnia and Herzegovina

Full Text Available The term ‘corporate governance’ stands for a set of relations between management, large and small shareholders and other interest groups. A good corporate governance system is the basic postulate of sustainable economic growth, increase in economic system efficiency and a guarantee for easier access to sources of foreign capital. Ownership concentration is a significant internal mechanism of corporate governance because it greatly defines the relationship between owner and manager. There are two types of ownership concentration: highly dispersed ownership, that is, low ownership concentration, and very high ownership concentration. These concentration differences affect the corporate governance system itself, so there is a difference between a closed corporate governance system in the situation of high ownership concentration and an open corporate governance system where the situation is the reverse. The form of the system affects how the governing body is formed and structured, as well as how it operates and conducts its business policies. Within the financial system of Bosnia and Herzegovina, the banking system is dominant. An analysis of the corporate governance system has shown a relationship between ownership concentration and the form of the corporate governance system itself. The banking sector is predominantly owned by foreign companies and is characterized by a high ownership concentration. The fact that the corporate governance system is closed affects the election of members to the governing body and their work in enforcing business policies.

Despite many efforts from government to address the shortage of medical officers (MOs) in rural areas, rural health centres continue to suffer from severe shortage of MOs. Lack of motivation to join and continue service in rural areas is a major reason for such shortage. In the present study, we aimed to assess and rank the driving factors of motivation important for in-service MOs in their current job. The study participants included ninety two in-service government MOs from three states in India. The study participants were required to rank 14 factors of motivation important for them in their current job. The factors for the study were selected using Herzberg's two-factor theory of motivation and the data were collected using an instrument that has an established reliability and validity. Test of Kendall's coefficient of concordance (W) was carried out to assess the agreement in ranks assigned by participants to various motivation factors. Next, we studied the distributions of ranks of different motivating factors using standard descriptive statistics and box plots, which gave us interesting insights into the strength of agreement of the MOs in assigning ranks to various factors. And finally to assess whether MOs are more intrinsically motivated or extrinsically motivated, we used Kolmogorov-Smirnov test. The (W) test indicated statistically significant (P factors than to extrinsic factors. The study results indicate that job security was the most important factor related to motivation, closely followed by interesting work and respect and recognition. Among the top five preferred factors, three were intrinsic factors indicating a great importance given by MOs to factors beyond money and job security. To address the issue of motivation, the health departments need to pay close attention to devising management strategies that address not only extrinsic but also intrinsic factors of motivation. The study results may be useful to understand the complicated issue of

We have investigated the feasibility of continuous infusion of undiluted factor IX (F IX) over several days using minipumps. The stabilities of seven different reconstituted F IX products were substantially better than those declared by the manufacturers. Several concentrates maintained factor activities 80% of baseline for the entire period of 4 weeks at 4-8d̀C as did one product at 20-23d̀A. At 37d̀C the latter concentrate was stable for at least 1 week. The stability seemed to correlate with the purity of the product. Analysis of two prothrombin comples concentrates by gel electrophoresis demonstrated degradation of prothrombin to prethrombin-1 and fragment 1 at 37d̀C and in one of the concentrates also at 20-23d̀C. In two F IX concentrates the corresponding analysis did not reveal any degradation. Four patients were treated with continuous infusion with a pure F IX concentrate (Mononine™, Armour) after surgery or for serious haemorrhage (two each) with good haemostatic effect, an initial progressive decrease of the F IX clearance, and no side-effects. Continuous infusion with F IX, using a minipump and undiluted reconstituted factor, is therefore feasible and effective, and can be conveniently prepared for several days at a time. Pure F IX products are more stable and probably safer for this purpose.

The objective of this study is to identify factors influencing unsafe use of hospital information systems in Malaysian government hospitals. Semi-structured interviews with 31 medical doctors in three Malaysian government hospitals implementing total hospital information systems were conducted between March and May 2015. A thematic qualitative analysis was performed on the resultant data to deduce the relevant themes. A total of five themes emerged as the factors influencing unsafe use of a hospital information system: (1) knowledge, (2) system quality, (3) task stressor, (4) organization resources, and (5) teamwork. These qualitative findings highlight that factors influencing unsafe use of a hospital information system originate from multidimensional sociotechnical aspects. Unsafe use of a hospital information system could possibly lead to the incidence of errors and thus raises safety risks to the patients. Hence, multiple interventions (e.g. technology systems and teamwork) are required in shaping high-quality hospital information system use.

Meteorological factors influencing on the radon concentrations in indoor and outdoor airs

International Nuclear Information System (INIS)

Kojima, Hiroshi

1989-01-01

Factors influencing radon concentrations in indoor and outdoor airs are discussed. A balance between source and loss is required in determining the radon concentration. Source refers to as the outdoor and indoor exhalation rate from the ground and the building materials. Loss is caused by turbulent diffusion outdoors and ventilation indoors. A significant factor influencing the exhalation rate of indoor and outdoor radon may be the change in atmospheric pressure. A drop of pressure feeds the high concentration air under the ground or building materials into the open air, and contributes to the increased exhalation rate. The exhalation rate of radon closely depends on the moisture content of the ground or building materials. Up to a certain level of moisture, the radon exhalation increases with increasing moisture content because the emanation power increases by a recoil effect of a fluid present in the internal pores of the materials. Beyond a certain level of moisture, the exhalation decreases rapidly because the pores are filled with water. Radon exhalated from the ground is spread out by turbulent diffusion. The turbulent diffusion may be related to wind velocity and the lapse rate of temperature. There is a remakable difference between indoor and outdoor radon concentrations. The ventilation rate of the house exerted a great effect upon the indoor radon concentration. The ventilation rate is influenced by meteorological factors together with human activities. Of such factors, wind velocity and temperature gradient between indoor and outdoor airs may be the most significant. The correlation coefficients between RaA or radon and some meteorological factors were calculated on the data from the long term measurements on radon and its decay products in and out of a house under normal living conditions. The changes in atmospheric pressure and wind velocity are found to be a significant factor in the variation of concentration of these nuclides. (N.K.)

Kulcinski, G. L.; Thompson, H.; Ott, S.

1989-01-01

Financial factors influencing the profitability of the mining and utilization of lunar helium-3 are examined. The analysis addressed the following questions: (1) which financial factors have the greatest leverage on the profitability of He-3; (2) over what range can these factors be varied to keep the He-3 option profitable; and (3) what ultimate effect could this energy source have on the price of electricity for U.S. consumers. Two complementary methods of analysis were used in the assessment: rate of return on incremental investment required and reduction revenue requirements (total cost to customers) achieved. Some of the factors addressed include energy demand, power generation costs with and without fusion, profitability for D-He(3) fusion, annual capital and operating costs, launch mass and costs, He-3 price, and government funding. Specific conclusions are made with respect to each of the companies considered: utilities, lunar mining company, and integrated energy company.

Craig, Christopher A.; Allen, Myria W.

2014-01-01

This study explores factors related to energy consumers' perceptions of government subsidies for utility provided energy efficiency (EE) programs and for utility providers' use of more clean/alternative energy sources. Demographic factors, attitudes, planned purchases, and perceptions of utility provider motives in relation to governmental and utility provider EE initiatives (i.e. providing discounts and coupons for CFL bulbs), plus the influence of gain- and loss-framed messages are investigated. Over 2000 respondents completed a 16 item phone survey. Hierarchical regression explained 38% of the variance in reactions regarding government subsidies of the cost of utility provided EE programs and 43% of the variance in perceptions involving whether utility companies should use of more clean or alternative forms of energy. Gender and party differences emerged. Loss-framed messages were more important when the issue was government subsidies. Both gain- and loss-framed messages were important when clean/alternative energy was the issue. - Highlights: • Over 2000 ratepayers were surveyed on their attitudes, planned behaviors and perceptions towards energy efficiency programs. • Almost 40% of how ratepayers feel about government subsidies and utility use of clean/alternative energy was explained. • Loss-framed messages were more effective when the dependent variable was ratepayer perception of government subsidies

Concentration factors of radionuclides in the marine organisms

International Nuclear Information System (INIS)

1996-03-01

Parameters related to the bioconcentration of radionuclides in the marine were shown by 'Assessment and guideline to the target value of dose in the environment of the power light water reactor facilities' (Nuclear Safety Commission), but the guideline data did not contain Ru and Ce relating to the reprocessing plant. So that more new data than these of 'Technical Reports Series No. 247' (published by IAEA in 1985) were mainly collected. Especially the data of nuclides with poor data of concentration factors (CF) and natural radionuclides (Po-210, Pb-210) were gathered. These data were pigeonholed and many tables (element, kinds of organisms, experimental methods) were made by separating the general remarks from the original experimental reports. The contents of this report are given as under, history of concentration factor (CF), determination method of CF, CF calculation method, calculation models related to CF, tables of metabolic parameters, tables of CF, the present conditions of studies for uptake of radionuclides with long half-life into the marine organisms, CF abstract tables and trial calculation of human exposure by eating the marine organisms.

Full Text Available ABSTRACT The purpose of this study was to have a fresh look at the local governance status through exploring governance factors affecting community participation in public development projects. The study also has investigated the actors and factors shaping participation as well as causes for non-participation. For the purpose of the study six wards within two divisions of Poli and Mbuguni and Meru district headquarters were selected. In the wards a total of 80 respondents from among the community members were interviewed through a structured questionnaire. Others were Village chairman Village Executive Officers Ward Executive Officers and Councilors were also interviewed and involved in the FGD. Data were analyzed using SPSS. Simple descriptive statistics and cross tabulation and figures were used in the analysis. The analysis showed that the communities were participated in the public development projects and people were participating through financial material and labor contribution to the public development projects. The analysis also showed that the government supported the ongoing public development projects including through provision of fund and expertise. The study showed the benefit of community participation in the development projects or programs like ownership of the projects and enjoying the benefits accrued from the projects. The study also indicated that there is significant change in terms of governance as influencers of community participation in public development projects. Despite the fortunes study showed some challenges found in wards and villages being the incidence of corruptions and misuse of public resources which were mentioned to slow community participation in public development projects. It was therefore concluded that adhering to the good governance principles contribute positively towards community participation in public development projects.

2005-06-01

Full Text Available The purpose of the analysis presented in the article is to identify various economic, social, political, demographic and cultural factors that could shape the differences in the size of government sector across countries and, with the use of econometric analysis empirically verify the effect of those factors. The analysis focuses only on ”budgetary” government, meaning that the size of government is measured with a certain government spending ratio. The results of the analysis revealed that economic factors are more important in explaining the variation in the size of government consumption spending, whereas political, social and cultural factors are more important in explaining the variation in the size of transfer spending. In addition, the results indicate that the relative size of government spending is inversely related to the extent of the regulation of the economy.

Factors affecting water strider (Hemiptera: Gerridae) mercury concentrations in lotic systems

Water striders (Hemiptera: Gerridae) have been considered as a potential sentinel for mercury (Hg) contamination of freshwater ecosystems, yet little is known about factors that control Hg concentrations in this invertebrate. Striders were collected from 80 streams and rivers in New Brunswick, Canada, in August and September of 2004 through 2007 to assess the influence of factors such as diet, water chemistry, and proximity to point sources on Hg concentrations in this organism. Higher than average Hg concentrations were observed in the southwest and Grand Lake regions of the province, the latter being the location of a coal-fired power plant that is a source of Hg (similar to 100 kg annually), with elevated Hg concentrations in the lichen Old Man's Beard (Usnea spp.) in its immediate vicinity. Across all streams, pH and total organic carbon of water were relatively weak predictors of strider Hg concentrations. Female striders that were larger in body size than males had significantly lower Hg concentrations within sites, suggestive of growth dilution. There was no relationship between percent aquatic carbon in the diet and Hg concentrations in striders. For those striders feeding solely on terrestrial carbon, Hg concentrations were higher in animals occupying a higher trophic level. Mercury concentrations were highly variable in striders collected monthly over two growing seasons, suggesting short-term changes in Hg availability. These measurements highlight the importance of considering both deposition and postdepositional processes in assessing Hg bioaccumulation in this species.

Factors Influencing Adaptive Marine Governance in a Developing Country Context: a Case Study of Southern Kenya

Directory of Open Access Journals (Sweden)

Louisa S. Evans

2011-06-01

Full Text Available Adaptive governance can be conceptualized as distinct phases of: 1 understanding environmental change; 2 using this understanding to inform decision making; and 3 acting on decisions in a manner that sustains resilience of desirable system states. Using this analytical framework, we explore governance in practice in two case studies in Kenya, that reflect the "messiness" of contemporary coastal governance in many developing country contexts. Findings suggest that adaptive marine governance is unlikely to be a smooth process of learning, knowledge sharing, and responding. There are institutional, sociocultural, and political factors, past and present, that influence each phase of both local and state decision making. New local institutions related to fisher associations and Beach Management Units influence learning and knowledge sharing in ways contrary to those expected of institutions that enable collaborative fisheries management. Similarly, state decision making is relatively uninformed by the diverse knowledge systems available in the coastal zone, despite the rhetoric of participation. Historical relations and modes of working continue to play a significant role in mediating the potential for adaptive governance in the future. The case studies are illustrative and point to a number of institutional and political issues that would need to be addressed in processes of governance reform towards more adaptive management in developing country contexts.

Accurate characterization of particle concentrations indoors is critical to exposure assessments. It is estimated that indoor particle concentrations depend strongly on outdoor concentrations. For health scientists, knowledge of the factors that control the relationship of indoor particle concentrations to outdoor levels is particularly important. In this paper, we identify and evaluate sources of data for those factors that affect the transport to and concentration of outdoor particles indoors. To achieve this goal, we (i) identify and assemble relevant information on how particle behavior during air leakage, HVAC operation, and particle filtration effects indoor particle concentration; (ii) review and evaluate the assembled information to distinguish data that are directly relevant to specific estimates of particle transport from those that are only indirectly useful; and (iii) provide a synthesis of the currently available information on building air-leakage parameters and their effect on indoor particle matter concentrations

1999-01-01

More than 20 years after the ban of DDT and other organochlorine pesticides, pesticides continue to be detected in air, rain, soil, surface water, bed sediment, and aquatic and terrestrial biota throughout the world. Recent research suggests that low levels of some of these pesticides may have the potential to affect the development, reproduction, and behavior of fish and wildlife, and possibly humans. Pesticides in Stream Sediment and Aquatic Biota: Distribution, Trends, and Governing Factors assesses the occurrence and behavior of pesticides in bed sediment and aquatic biota-the two major compartments of the hydrologic system where organochlorine pesticides are most likely to accumulate. This book collects, for the first time, results from several hundred monitoring studies and field experiments, ranging in scope from individual sites to the entire nation. Comprehensive tables provide concise summaries of study locations, pesticides analyzed, and study outcomes. Comprehensive and extensively illustrated, Pesticides in Stream Sediment and Aquatic Biota: Distribution, Trends, and Governing Factors evaluates the sources, environmental fate, geographic distribution, and long-term trends of pesticides in bed sediment and aquatic biota. The book focuses on organochlorine pesticides, but also assesses the potential for currently used pesticides to be found in bed sediment and aquatic biota. Topics covered in depth include the effect of land use on pesticide occurrence, mechanisms of pesticide uptake and accumulation by aquatic biota, and the environmental significance of observed levels of pesticides in stream sediment and aquatic biota.

Pintea Mirela-Oana

2015-07-01

Full Text Available In the matter of corporate governance reforms, an important aspect is whether the implementation of corporate governance principles and codes has a positive impact on firm performance. The literature testing the relationship between different corporate governance mechanisms and firm performance is extensive. Over time, a lot of corporate governances mechanisms were studied in relation to firm performance and the most used are: CEO duality, board size, proportion of non- executive directors, board committees, ownership structure and concentration, managers’ compensation and incentives schemes. With time, different authors began to use more comprehensive measures for corporate governance rather than a single variable or a single governance mechanism, the so called corporate governance indexes. Regarding performance there are three main approaches to firm performance in social science research: research based on market prices, accounting ratios and total factor profitability.The most used performance measures are: Tobin’s Q, return on equity, return on asset and economic value added. In our paper, we present the studies undertaken since the 1990’s regarding the relationship between different mechanisms of corporate governance and firm performance and between corporate governance index and performance for both developed and developing countries around the world. Regarding the working tools used in this theoretical research we can mention the longitudinal method, by presenting the evolution in time of empirical studies on the research topic and the comparative method used in presenting the resulys of different studies mentioned in our paper. The results of the studies are inconclusive, some studies founded a strog positive relation, others founded a negative correlation between corporate governance and firm performance, while a third category of studies didn’t found any relationship at all. We used participative observation method by issuing

2014-06-01

Full Text Available In the developed stock markets the corporate governance aspect is crucial in the stock portfolio selection process for investor seeking to achieve shareholder value sustainability. In the emerging markets the importance of the corporate governance role just starts to be realized by the investors and by the corporate managers. The present research, looking at the stock performance leaders and laggards, analyzes whether the corporate governance system matters to achieve long-term shareholder value within the Central and Eastern European stock markets universe. Corporate governance quality was assessed and compared among the out- and underperformers. The financial results plausibility and the ownership structure were considered as well. Additionally, the authors analyzed whether the quality of corporate governance influences the economic performance of the company. The obtained results provide the proof that the corporate governance does matter as the market outperformers have above average corporate governance quality and provide trustworthy financial results more often than the underperforming companies. Besides, well-governed companies are also able to deliver more attractive financial results.

Change Management as a Critical Success Factor in e-Government Implementation

Directory of Open Access Journals (Sweden)

Janja Nograšek

2011-01-01

Full Text Available Change management in e-government implementation is a very complex issue. E-government services are frequently distributed over different IT systems and organizations. There are also events from outside the public administration that cause changes such as government policies and legislation, public-private partnership, etc., and finally a huge resistance to change exists in public administration proverbial. Another problem is that the e-government is predominantly seen only as a technology mission and not as an organizational transformation issue. Those are probably the main reasons that the existing literature about change management in e-government is still missing at large. There are articles dealing with some aspects of changes affected by the new technology implementation, however, there is no comprehensive framework that would identify changes that have to be managed in e-government implementation. Therefore, the main aim of the paper is to identify a comprehensive set of changes that have to be considered in e-government implementation and the role of leadership in such processes. Finally, the paper proposes a conceptual model of change management in e-government implementation.

This study was conducted to determine the concentration and to measure platinum group elements (PGE) transfer factor in environmental samples of roadside soil and vegetation. The use of vehicle catalytic converter has released platinum group elements (PGE) and other gases into the environment. Thus, roadside soil and plants were exposed to this element and has become the medium for the movement of this elements. Samples of roadside soil and vegetation were taken at various locations in UKM Bangi Toll and the concentration of platinum group elements (PGE) is determined using mass spectrometry-inductively coupled plasma (ICP-MS). Overall, the concentrations of platinum group elements (PGE), which is the element platinum (Pt) in soil was 0.016 ± 0.036 μgg -1 . While the concentration of the elements palladium (Pd) was 0.079 ± 0.019 μgg -1 and element rhodium (Rh) is at a concentration of 0.013 ± 0.020 μgg -1 . Overall, the transfer factor for the element platinum (Pt) is 1. While the transfer factor of the element palladium (Pd) is 0.96 and the element rhodium (Rh) is 1.11. In conclusion, the concentration of platinum group elements (PGE) in soils have increased. (author)

However, the effects of dietary factors on toenail arsenic concentrations in well-nourished populations exposed to relatively low levels of water arsenic are unknown. Methods As part of a population-based case–control study of skin and bladder cancer from the USA, we evaluated relationships between consumption of dietary factors and arsenic concentrations in toenail clippings. Consumption of each dietary factor was determined from a validated food frequency questionnaire. We used general linear models to examine the associations between toenail arsenic and each dietary factor, taking into account potentially confounding effects. Results As expected, we found an inverse association between ln-transformed toenail arsenic and consumption of vitamin B12 (excluding supplements and animal protein. Unexpectedly, there were also inverse associations with numerous dietary lipids (e.g., total fat, total animal fat, total vegetable fat, total monounsaturated fat, total polyunsaturated fat, and total saturated fat. Finally, increased toenail arsenic concentrations were associated with increased consumption of long chain n-3 fatty acids. Conclusion In a relatively well-nourished population exposed to relatively low levels of arsenic via water, consumption of certain dietary lipids may decrease toenail arsenic concentration, while long chain n-3 fatty acids may increase toenail arsenic concentration, possibly due to their association with arsenolipids in fish tissue.

SHAPE EFFECT OF ANNULAR CONCENTRATOR IN ULTRASONIC SYSTEM ON AMPLIFICATION FACTOR OF VIBRATIONS AMPLITUDE

Directory of Open Access Journals (Sweden)

D. A. Stepanenko

2016-01-01

Full Text Available The paper contains a theoretical underpinning on creation of ultrasonic vibration concentrators based on annular elastic elements with non-circular (ellipse-like eccentric shape of internal contour. Shape of internal contour in polar coordinates is described by Fourier series relative to angular coordinate that consists of a constant term and first and second harmonics. An effect of geometric parameters of the concentrator on amplification factor and natural vibration frequencies has been investigated with the help of a finite element method. The paper reveals the possibility to control an amplification factor of annular concentrators while varying eccentricity of internal contour and mean value of cross-section thickness. The amplification factor satisfies a condition K < N, where N is thickness ratio of amplifier input and output sections, and it is decreasing with increase of vibration mode order. The similar condition has been satisfied for conical bar concentrator with the difference that in the case of bar concentrators an amplification is ensured due to variation of diameter and N will represent ratio of diameters. It has been proved that modification of internal contour shape makes it possible to carry out a wide-band tuning of natural frequencies of concentrator vibrations without alteration of its overall dimensions and substantial change of amplification factor, which is important for frequency matching of the concentrator and ultrasonic vibratory system. Advantages of the proposed concentrators include simplicity of design and manufacturing, small overall dimensions, possibility for natural frequency tuning by means of static load variation. The developed concentrators can find their application in ultrasonic devices and instruments for technological and medical purposes.

Full Text Available To determine the status of serum zinc in pregnant women in different gestational ages and correlation with socio-demographic and anthropometric factors in Iranian women referring to prenatal care public health clinics.We analyzed the zinc concentrations in plasma samples obtained at different gestational ages from 961 women and recorded BMI at the first trimester in pregnant women who were screened for a trial designed to evaluate the zinc concentration. Subjects were from different socio economical backgrounds and attended public health clinics for their prenatal care. All analyses were performed by SPSS (version 16. P values < 0.05 were considered significant.The results showed that after plasma zinc concentrations were adjusted with Parity, weight (early pregnancy, BMI (at early pregnancy, age and educational statues. Plasma zinc deficiency declined as gestational age progressed, however it was not significant. There was no significant correlation between zinc concentration, anthropometric, method of contraception and socio factors. However, there were significant relation between parity (p = 0.007 and weight at early pregnancy (p= 0.039 with serum zinc levels.We conclude that plasma zinc concentrations decreased during the late first trimester to the early third trimester and with parity. These findings may indicate that the deficient levels of zinc in the latter third of pregnancy suggest a tendency for insufficient maternal nutrition. However larger studies are required to support this finding.

Borgoni, Riccardo; De Francesco, Davide; De Bartolo, Daniela; Tzavidis, Nikos

2014-12-01

Radon is a natural gas known to be the main contributor to natural background radiation exposure and only second to smoking as major leading cause of lung cancer. The main concern is in indoor environments where the gas tends to accumulate and can reach high concentrations. The primary contributor of this gas into the building is from the soil although architectonic characteristics, such as building materials, can largely affect concentration values. Understanding the factors affecting the concentration in dwellings and workplaces is important both in prevention, when the construction of a new building is being planned, and in mitigation when the amount of Radon detected inside a building is too high. In this paper we investigate how several factors, such as geologic typologies of the soil and a range of building characteristics, impact on indoor concentration focusing, in particular, on how concentration changes as a function of the floor level. Adopting a mixed effects model to account for the hierarchical nature of the data, we also quantify the extent to which such measurable factors manage to explain the variability of indoor radon concentration.

The European Union economic governance incorporates some key features, namely in this case the decisions are made as a result of an interconnected action between a complex network that implies different levels of governing. The purpose of this article is to investigate the obstacles that the process of EU economic governance had to overcome during the recent financial crisis and the measures that the responsible authorities adopted in order to improve the general efficiency of this system. The main conclusion of this article is that the recent financial crisis highlight the limits that the European Union economic governance had in implementing economic policies that assure a smooth path towards sustainable growth and convergence in the context of a continuous process of integration between the member states. The new model of economic governance concentrates upon a mechanism of monitoring and early reporting of any macroeconomic imbalances as well as an intensified monitoring activity within the budgetary field.

2014-06-01

Full Text Available The purpose of the article is to address issues of auditing in the context of financial management as a contribution to good governance. Generally, not all local governments have effective and operational audit units and committees. As a result, auditing is not used as an essential element of good governance and this leads to bad audit outcomes like disclaimers and adverse opinions. The bad audit outcomes in local government have motivated the researcher to conduct the study on auditing. There are internal factors within the municipalities as well as external factors that are of interest and directed the researcher to have desire and commitment to make a contribution in this particular field of research. The key issues, amongst others, are principles of financial management, financial strategy, auditing functions such as forensic auditing, fraud auditing, forensic accounting and detection of fraud, including accounting systems and auditor’s role. This article will also attempt to reinforce existing theories and add value to local government financial discourse and good governance.

Full Text Available Bench-scale systems are often used to evaluate pretreatment methods and operational conditions that can be applied in full-scale ultrafiltration (UF systems. However, the membrane packing density is substantially different in bench and full-scale systems. Differences in concentration factor (CF at the solution–membrane interface as a result of packing density may impact the mass transfer and fouling rate and the applicability of bench-scale systems. The present study compared membrane resistance when considering raw water (CF = 1 and reject water (also commonly referred to as concentrate water (CF > 1 as feed in UF systems operated in deposition (dead-end mode. A positive relationship was observed between the concentration of the organic matter in the solution being filtered and resistance. Bench-scale trials conducted with CF = 1 water were more representative of full-scale operation than trials conducted with elevated CFs when considering membrane resistance and permeate quality. As such, the results of this study indicate that the use of the same feed water as used at full-scale (CF = 1 is appropriate to evaluate fouling in UF systems operated in deposition mode.

Corporate Governance and Pension Fund Performance

Directory of Open Access Journals (Sweden)

Oskar Kowalewski

2012-03-01

Full Text Available This study provides new evidence on the impact of governance on the performance of privately defined contribution pension plans. Using a hand collected data set on governance factors, the study shows that the external and internal governance mechanisms in pension plans are weak. One explanation for this weakness is the potential conflict between the pension beneficiaries and the fund’s owner, which depends on who bears the investment risk in the pension plan. Hence, different governance factors are found to be important for pension fund return on invested assets and also for its economic performance. Consequently, the overall policy conclusion is that more focus should be put on the governance of the pension funds, taking into account the different interests of the beneficiaries and owners as it may determine their performance.

Objective Corticotropin-releasing factor (CRF) and somatostatin both play important roles in mediating responses to acute and chronic stress. The purpose of this study was to measure CSF concentrations of CRF and somatostatin in patients with chronic combat-related post-traumatic stress disorder (PTSD) and comparison subjects. Method Lumbar punctures for collection of CSF were performed in Vietnam combat veterans with PTSD (N=11) and comparison subjects (N=17). CSF concentrations of CRF and somatostatin were compared between the two groups. Results CSF concentrations of CRF were higher in the PTSD patients than in the comparison subjects (mean=29.0 pg/ml, SD=7.8, versus mean=21.9 pg/ml, SD=6.0). This group difference remained significant after covariance for age. CSF somatostatin concentrations in PTSD patients were higher than those of the comparison subjects (mean=19.9 pg/ml, SD=5.4, versus mean=13.7 pg/ml, SD=8.0). However, covarying for age reduced the level of significance. Conclusions Higher CSF CRF concentrations in patients with PTSD may reflect alterations in stress-related neurotransmitter systems. The higher CSF CRF concentrations may play a role in disturbances of arousal in patients with PTSD. PMID:9137116

How they affect the development product of Albania, not only as a concept, and a principle but mostly as a sensitive aspect in the integration process. There are some interpretations of this concept, but I intend to analyze the key factors and actors, their cooperation and concrete production in society. Improving governance is necessary to have an integrated long term strategy based upon a continuous cooperation between institutions and citizens. But in developing countries like Albania there are some important questions such as: How can we measure the improvement of Good Governance through policies? Has Good Governance indicated an effective way for the sustainable development? (Meisel, 2008, 6. These question give us the orientation to reflect about the process of development, social economic political behavior and how this multidimensional is transformed in product of good governance. The business cycle is strongly connected with many aspects of political-, social-, juridical aspects and good governance. Despite attempts to draft law regulations, the level of corruption and informality in Albania continues to be a major obstacle. The credibility level in the implementation of law is an indicator that affects democratization and institutional integration. At present, different reports of international institutions, define Albania as the country with the highest level of Corruption in the Balkans, which is a key factor influencing business.

Monoclonal antibody purified factor IX concentrate, Mononine (Armour Pharmaceutical Company, Kankakee, Illinois, USA), is a recently developed replacement factor concentrate for the treatment of patients with hemophilia B. The pharmacokinetic properties of monoclonal antibody purified factor IX concentrate (MAb Factor IX concentrate) have been evaluated in only small samples of patients, and little is known about those factors that might influenced in vivo recovery of factor IX after infusion is a larger patient population. In vivo recovery of factor IX was therefore evaluated for 80 different indications in 72 patients who received MAb Factor IX concentrate for the management of spontaneous or trauma-induced bleeding, or as prophylaxis with surgery. The average recovery after infusions for presurgical pharmacokinetic analysis (mean +/- standard deviation) was 1.28 +/- 0.56 U/dl rise per U/kg infused (range 0.41-2.80), and the average recovery after all infusions for treatment was 1.23 +/- 0.49 U/dl rise per U/kg infused (range - 0.35-2.92). Recovery values for multiple MAb Factor IX doses in a given patient were also variable; the average recovery was 1.22 +/- 0.53 U/dl rise per U/kg given, and standard deviations ranged from 0.03 to 1.26. Patient age, weight, and MAb Factor IX concentrate dose minimally but significantly influenced factor IX recovery. There was no significant effect of either race, history of previous thrombotic complications during treatment with other replacement factor concentrates, or bleeding state on recovery. All of the patients treated with this preparation experienced excellent hemostasis, and no thrombotic complications were observed.

Full Text Available Duality of the role of President of the Board of Directors (BoD and CEO has been regarded as a good practice of corporate governance. These two roles are the ones with the most power an authority within the corporation. The paper depicts the formulating factors of duality of roles in Greece. Literature has linked duality with performance, organizational stability, ownership concentration and balance of power and control within the firm. The paper, using a Probit regression analysis, examines whether these relationships are valid in Greece. Statistical – econometric analysis has shown that financial performance is not related with concentration of power and control. The same conclusion is can be drawn for ownership concentration. There is a trend of change but this trend hasn’t the same dynamic or driving factors as the ones that are reported by Kirkbride and Letza (2002 and Muth and Donaldson (1998. The hypothesis posed by Heracleous (2001 and Baliga, 6oyer and Rao (1996 are more likely to be true in the case of Greece. Overall, duality in Greece is affected by the historical development of the firm, its organizational scheme and even more by the balance of power and control within the firm.

Governance in Health - The Need for Exchange and Evidence Comment on "Governance, Government, and the Search for New Provider Models".

Science.gov (United States)

Chanturidze, Tata; Obermann, Konrad

2016-05-17

Governance in health is cited as one of the key factors in balancing the concerns of the government and public sector with the interests of civil society/private players, but often remains poorly described and operationalized. Richard Saltman and Antonio Duran look at two aspects in the search for new provider models in a context of health markets signalling liberalisation: (i) the role of the government to balance public and private interests and responsibilities in delivering care through modernised governance arrangements, and (ii) the finding that operational complexities may hinder well-designed provider governance models, unless governance reflects country-specific realities. This commentary builds on the discussion by Saltman and Duran, and argues that the concept of governance needs to be clearly defined and operationalized in order to be helpful for policy debate as well as for the development of an applicable framework for performance improvement. It provides a working definition of governance and includes a reflection on the prevailing cultural norms in an organization or society upon which any governance needs to be build. It proposes to explore whether the "evidence-based governance" concept can be introduced to generate knowledge about innovative and effective governance models, and concludes that studies similar to the one by Saltman and Duran can inform this debate. © 2016 by Kerman University of Medical Sciences.

Endometriosis is a sex hormone-dependent and successively progressing gynecological disease, characterized by the presence of endometrial tissue outside the uterus. The etiology of endometriosis is known to be multifactorial, and its growth depends on immunological, hormonal, genetic and environmental factors. Angiogenesis plays a key role in implantation and growth of endometriotic lesions, as well as in adhesion formation. Physiologically angiogenesis is responsible for neoangiogenesis and recruitment of new capillaries from the already existing capillaries. It is well-documented that altered angiogenesis provokes improper follicular maturation, infertility recurrent miscarriages, ovarian hyperstimulation syndrome, and carcinogenesis. Factors stimulating angionesis include angiogenin, vascular endothelial growth factor (VEGF) and fibroblast growth factor (FGF). The aim of the study was to analyze angiogenic factor concentration (angiogenin, VEGF, FGF) in blood serum and peritoneal fluid in patients with diagnosed endometriosis and idiopathic infertility. A total of 39 patients were recruited for the study including 19 patients (study group) diagnosed with endometriosis during the laparoscopic procedure and 20 patients (control group) with idiopathic infertility and no morphologic changes within the pelvis revealed during the laparoscopic procedure. All patients underwent laparoscopy during the follicular phase of the menstrual cycle. Vein blood sample was obtained before the procedure and during laparoscopy the entire peritoneal fluid was aspirated for further measurement of VEGF, FGF and angiogenin concentrations. Angiogenin concentration in peritoneal fluid was statistically higher in patient with idiopathic infertility in comparison to endometriosis (pendometriosis, but no statistical significance was found. VEGF and FGF concentration in blood serum and peritoneal fluid was similar in both groups (p>0.05). There were no significant differences between serum

Stress concentration factors for pressurized elliptic crossbores in blocks

Badr, Elie A.

2006-01-01

Intersecting bore geometries are used in a number of industrial applications including heavy-walled pressure vessels containing oil holes for lubrication, ports for valves and fluid ends of reciprocating pumps. The bore intersection location is a stress concentration point where the maximum hoop stress can be many times the fluid pressure in the bores. Intersecting circular holes in heavy-walled cylinders and rectangular blocks have been extensively investigated. Specifically, stress/pressure concentration curves for intersecting circular bores in rectangular blocks were presented by Sorem et al. [Sorem JR, Shadley JR, Tipton SM. Design curves for maximum stresses in blocks containing pressurized bore intersections. ASME J Mech Des 1990; 113: 427-31.]. However, stress/pressure concentrations due to intersecting elliptic bores have not been broadly investigated. With the availability of computer numerical control (CNC) machinery, bores with elliptic crosssection can be produced with relative ease. In this paper, hoop stress concentration ratios are developed for elliptic crossbores in rectangular blocks. Results indicate that introducing elliptic crossbores, rather than circular ones, significantly reduces the hoop stress concentration factor at the crossbore intersection. Also, the presence of intersecting crossbores has a major effect on the fatigue life of pressure vessels [Badr EA, Sorem JR, Jr Tipton SM. Evaluation of the autofrettage effect on fatigue lives of steel blocks with crossbores using a statistical and a strain-based method. ASTM J Test Eval 2000; 28: 181-8.] and the reduction of hoop stress concentration is expected to enhance the fatigue life of pressure vessels containing crossbores

2016-04-01

Full Text Available In this study, the positive matrix factorization (PMF receptor model (version 5.0 was used to identify and quantify major sources contributing to particulate matter (PM number concentrations, using PM number size distributions in the range of 13 nm to 10 µm combined with several auxiliary variables, including black carbon (BC, elemental and organic carbon (EC/OC, PM mass concentrations, gaseous pollutants, meteorological, and traffic counts data, collected for about 9 months between August 2014 and 2015 in central Los Angeles, CA. Several parameters, including particle number and volume size distribution profiles, profiles of auxiliary variables, contributions of different factors in different seasons to the total number concentrations, diurnal variations of each of the resolved factors in the cold and warm phases, weekday/weekend analysis for each of the resolved factors, and correlation between auxiliary variables and the relative contribution of each of the resolved factors, were used to identify PM sources. A six-factor solution was identified as the optimum for the aforementioned input data. The resolved factors comprised nucleation, traffic 1, traffic 2 (with a larger mode diameter than traffic 1 factor, urban background aerosol, secondary aerosol, and soil/road dust. Traffic sources (1 and 2 were the major contributor to PM number concentrations, collectively making up to above 60 % (60.8–68.4 % of the total number concentrations during the study period. Their contribution was also significantly higher in the cold phase compared to the warm phase. Nucleation was another major factor significantly contributing to the total number concentrations (an overall contribution of 17 %, ranging from 11.7 to 24 %, with a larger contribution during the warm phase than in the cold phase. The other identified factors were urban background aerosol, secondary aerosol, and soil/road dust, with relative contributions of approximately 12�

Full Text Available The issue of corporate governance has become increasingly important as globalisation has begun to accelerate and the economic and financial turmoil have intensified. Post-crisis context has imposed the need to expand the prospects for analysis over governance and companies, as well as the need to identify new ways of administration and resource management. From this perspective, the author aims to highlight the conditions, factors and events that have generated profound changes within the business environment, while the analysis is focusing on contemporary changes in the systems of corporate governance and economic mutations, especially in terms of the companies. The establishment of new governance rules is demanding a theoretical approach based on new methodological requirements which are needed to reform theoretical foundations and to promote creative and effective shapes and governance systems.

Chronically nitrate-loaded riparian buffer zones show high N 2 O emissions. Often, a large part of the N 2 O is emitted from small surface areas, resulting in high spatial variability in these buffer zones. These small surface areas with high N 2 O emissions (hotspots) need to be investigated to generate knowledge on the factors governing N 2 O emissions. In this study the N 2 O emission variability was investigated at different spatial scales. Therefore N 2 O emissions from three 32 m 2 grids were determined in summer and winter. Spatial variation and total emission were determined on three different scales (0.3 m 2 , 0.018 m 2 and 0.0013 m 2 ) at plots with different levels of N 2 O emissions. Spatial variation was high at all scales determined and highest at the smallest scale. To test possible factors inducing small scale hotspots, soil samples were collected for slurry incubation to determine responses to increased electron donor/acceptor availability. Acetate addition did increase N 2 O production, but nitrate addition failed to increase total denitrification or net N 2 O production. N 2 O production was similar in all soil slurries, independent of their origin from high or low emission soils, indicating that environmental conditions (including physical factors like gas diffusion) rather than microbial community composition governed N 2 O emission rates

Full Text Available Sun exposure is the main source of vitamin D. Due to many lifestyle risk factors vitamin D deficiency/insufficiency is becoming a worldwide health problem. Low 25(OHD concentration is associated with adverse musculoskeletal and non-musculoskeletal health outcomes. Vitamin D supplementation is currently the best approach to treat deficiency and to maintain adequacy. In response to a given dose of vitamin D, the effect on 25(OHD concentration differs between individuals, and it is imperative that factors affecting this response be identified. For this review, a comprehensive literature search was conducted to identify those factors and to explore their significance in relation to circulating 25(OHD response to vitamin D supplementation. The effect of several demographic/biological factors such as baseline 25(OHD, aging, body mass index(BMI/body fat percentage, ethnicity, calcium intake, genetics, oestrogen use, dietary fat content and composition, and some diseases and medications has been addressed. Furthermore, strategies employed by researchers or health care providers (type, dose and duration of vitamin D supplementation and environment (season are other contributing factors. With the exception of baseline 25(OHD, BMI/body fat percentage, dose and type of vitamin D, the relative importance of other factors and the mechanisms by which these factors may affect the response remains to be determined.

Vaccines have greatly contributed to the control of vaccine-preventable diseases and to human development. Efforts by many countries to introduce new vaccines are a significant move towards achieving the sustainable development goal for health. However, effective vaccine supply chains that ensure an uninterrupted supply of vaccines are pivotal to attaining universal access to life-saving vaccines and sustainable development. The introduction of new vaccines puts a strain on supply chains; South Africa (SA) is no exception, as there are indications of vaccine stock-outs in clinics. To establish the status of vaccine availability and associated factors in government health facilities of Tshwane Health District in Gauteng Province, SA. A cross-sectional study was conducted in a sample of randomly selected government clinics in the Tshwane health district of Gauteng Province. Data were collected using a structured measurement instrument in participating clinics. Data were analysed using Excel-based software (Microsoft, USA). A total of 31 clinics participated. In the preceding 12 months, clinics had experienced vaccine stock-outs, especially of the three newer vaccines: pneumococcal conjugate vaccine, rotavirus and Pentaxim. These were also out of stock for a long duration; for over 2 weeks in a majority of clinics. The causes of vaccine stock-outs were: poor management of stock, district depot out of stock, unreliable deliveries, lack of pharmacy assistants and limited fridge capacity. Further burdening the situation is the ineffective emergency-ordering system. Significant shortages of vaccines, which are essential drugs, occur in Tshwane government clinics. Vaccine supply chain issues and vaccine shortages should be treated as a priority at all levels of the healthcare system; therefore, a similar study should be conducted at national level. It is recommended that the vaccine supply chain should be restructured and overhauled with the use of advances in technology

E-GOVERNMENT: A DRIVING FACTOR FOR STIMULATING INNOVATION PERFORMANCE IN ROMANIA?

Full Text Available The development of public services is one of the priorities on the agendas of all policies, both national and European. One of the most recent concerns of the European Commission, as shown in the 2010 Innobarometer, is to find ways and develop strategies to support the innovation in the public administration sector, in the context of the continuously changing economic background. In this paper, we'll investigate the relationship between e-Government, and the overall innovation performance at national level, for some European Union countries. e-Government is already a known concept, widespread in the world, promoting the implementation of information and communication technologies in the public administration, in order to provide better public services to citizens and businesses. A main component of the e-Government concept is the 'counter reform', aimed to streamlining administrative act quickly in order to respond to the demands of citizens, businesses and government structures. Innovation in e-Government will be measured with two Eurostat indicators e-Government on-line availability and e-Government usage by individuals while for the overall innovation performance we'll use a composite indicator the Summary Innovation Index (SII - from the Innovation Union Scoreboard (IUS. In Romania, even if the values of these indicators are not at the level of other EU countries, we can say that the situation has improved and electronic public services are being used increasingly often. The study also includes a comparison between two modest innovators: Romania and Bulgaria. Regarding the overall innovation performance, according to the 2010 Innovation Union Scoreboard ranking, Romania is the leader of the modest innovators countries, overcoming Latvia, Bulgaria and Lithuania. However, in the field of e-Government our country has major shortcomings. Romania has registered a significant progress in the years after the EU integration, followed by a setback in

2006-01-01

While there has been extensive research in defining project organizational structures for traditional projects, little research exists to support high technology government project s organizational structure definition. High-Technology Government projects differ from traditional projects in that they are non-profit, span across Government-Industry organizations, typically require significant integration effort, and are strongly susceptible to a volatile external environment. Systems Integration implementation has been identified as a major contributor to both project success and failure. The literature research bridges program management organizational planning, systems integration, organizational theory, and independent project reports, in order to assess Systems Integration (SI) organizational structure selection for improving the high-technology government project s probability of success. This paper will describe the methodology used to 1) Identify and assess SI organizational structures and their success rate, and 2) Identify key factors to be used in the selection of these SI organizational structures during the acquisition strategy process.

Full Text Available Growing importance of information technology (IT, as a strategic factor for organizations in achieving their objectives, have raised the concern of organizations in establishing and implementing effective IT governance. This study seeks to empirically examine the individual IT governance mechanisms that influence the overall effectiveness of IT governance. The data were obtained by using web based survey from 176 members of ISACA (Information Systems and Audit Control Association Australia. This study examines the influences of six proposed IT governance mechanisms on the overall effectiveness of IT governance. Using Factor Analysis and Multiple Regression techniques, the current study finds significant positive relationships between the overall level of effective IT governance and the following four IT governance mechanisms: the existence of ethics/ culture of compliance in IT, corporate communication systems, an IT strategy committee, and the involvement of senior management in IT.

Correlation of Stress Concentration Factors for T-Welded Connections – Finite Element Simulations and Fatigue Behavior

Directory of Open Access Journals (Sweden)

Gerardo Terán Méndez

Full Text Available Abstract The stress concentration factors (SCFs in welded connections usually occur at zones with high stress levels. Stress concentrations reduce the fatigue behavior of welded connections in offshore structures and cracking can develop. By using the grinding technique, cracking can be eliminated. Stress concentration factors are defined as a ratio of maximum stress at the intersection to nominal stress on the brace. Defining the stress concentration factor is an important stage in the fatigue behavior of welded connections. Several approaches have evolved for designing structures with the classical S-N approach for estimating total life. This work correlates to the stress concentration factors of T-welded connections and the fatigue behavior. Stress concentration factors were computed with the finite element employing 3D T-welded connections with intact and grinding depth conditions. Then, T-welded connections were constructed with A36 plate steel and welded with E6013 electrodes to obtain the stress-life (S-N approach. The methodology from previous works was used to compute the SCF and fabricate the T-welded connections. The results indicated that the grinding process could restore the fatigue life of the T-welded connections for SCFs values in the range of 1.29. This value can be considered to be a low SCF value in T-welded connection. However, for higher SCF values, the fatigue life decreased, compromising and reducing the structural integrity of the T-welded connections.

Study of factors governing US utility nuclear power decisions

International Nuclear Information System (INIS)

1980-05-01

Under DOE contract No. DE-AC02-79ET34009, The S.M. Stoller Corporation has conducted a study of US utility attitudes toward nuclear power. In the course of this study SMSC carried out a utility survey the objectives of which were: (1) to identify and rank in importance the governing considerations in actions taken in the past three years to cancel or defer nuclear projects, and (2) to gain insight into the circumstances and attitudes likely to govern new base-load commitments over the next several years. During the survey, contacts were made at the senior management level with utilities representing approximately half of the country's total electric capacity and two-thirds of its present nuclear commitment. Analysis of the responses led to the conclusion that most, if not all, of the decisions reached by the respondent utilities in the past several years to cancel or defer nuclear projects were triggered by one or a combination of the following four considerations: financial constraints; reduction in expected system load growth; schedule delay in licensing and construction and/or unpredictability; and adverse state government policies or attitudes regarding nuclear power

Physiological epidermal growth factor concentrations activate high affinity receptors to elicit calcium oscillations.

Directory of Open Access Journals (Sweden)

Béatrice Marquèze-Pouey

Full Text Available Signaling mediated by the epidermal growth factor (EGF is crucial in tissue development, homeostasis and tumorigenesis. EGF is mitogenic at picomolar concentrations and is known to bind its receptor on high affinity binding sites depending of the oligomerization state of the receptor (monomer or dimer. In spite of these observations, the cellular response induced by EGF has been mainly characterized for nanomolar concentrations of the growth factor, and a clear definition of the cellular response to circulating (picomolar concentrations is still lacking. We investigated Ca2+ signaling, an early event in EGF responses, in response to picomolar doses in COS-7 cells where the monomer/dimer equilibrium is unaltered by the synthesis of exogenous EGFR. Using the fluo5F Ca2+ indicator, we found that picomolar concentrations of EGF induced in 50% of the cells a robust oscillatory Ca2+ signal quantitatively similar to the Ca2+ signal induced by nanomolar concentrations. However, responses to nanomolar and picomolar concentrations differed in their underlying mechanisms as the picomolar EGF response involved essentially plasma membrane Ca2+ channels that are not activated by internal Ca2+ store depletion, while the nanomolar EGF response involved internal Ca2+ release. Moreover, while the picomolar EGF response was modulated by charybdotoxin-sensitive K+ channels, the nanomolar response was insensitive to the blockade of these ion channels.

'Good Governance' dan 'Governability'

Directory of Open Access Journals (Sweden)

- Pratikno

2005-03-01

Full Text Available The article endeavors to trace the outset of governance concept, its dominant meanings and discourse, and its implication towards governability. The central role of government in the governing processes has predominantly been adopted. The concept of governance was emerged precisely in the context of the failure of government as key player in regulation, economic redistribution and political participation. Governance is therefore aimed to emphasize pattern of governing which are based both on democratic mechanism and sound development management. However, practices of such good governance concept –which are mainly adopted and promoted by donor states and agencies– tend to degrade state and/or government authority and legitimacy. Traditional function of the state as sole facilitator of equal societal, political and legal membership among citizens has been diminished. The logic of fair competition has been substituted almost completely by the logic of free competition in nearly all sectors of public life. The concept and practices of good governance have resulted in decayed state authority and failed state which in turn created a condition for "ungovernability". By promoting democratic and humane governance, the article accordingly encourages discourse to reinstall and bring the idea of accountable state back in.

Full Text Available Good Governance is one of the essential factors of success in business as well as in a country’s development. This study aimed at examining the role of good governance and the success of the development. The comparable per head GDP measured in PPP (purchasing power parity was used as the proxy of the successful economic development of countries in the study. Four out of total six factors (indicators being the good governance and the other two being social environmental factors were employed in the investigation following concept of the role of external business environmental factors so called “PESTLE or Political, Economic, Social, Technological, Legislative or Legal, and Eco-environmental analysis”. These four indicators of good governance are political stability, control of corruption, rule of law, and voice and accountability which are available from the World Bank’s governance project data base. In addition, the other two indicators, country’s openness and size of population, are the major social variables included in the study which can also affect the success. The total six indicators are taken to examine with the GDP per head to see whether these factors can help countries achieve higher levels of income per head. The study indicates connection between the levels of success with these four indicators of the good governance and the two external social variables. For Thailand, the political instability was found to be a problem of the progress of development among those six indicators.

Governance in Health – The Need for Exchange and Evidence; Comment on “Governance, Government, and the Search for New Provider Models”

2016-08-01

Full Text Available Governance in health is cited as one of the key factors in balancing the concerns of the government and public sector with the interests of civil society/private players, but often remains poorly described and operationalized. Richard Saltman and Antonio Duran look at two aspects in the search for new provider models in a context of health markets signalling liberalisation: (i the role of the government to balance public and private interests and responsibilities in delivering care through modernised governance arrangements, and (ii the finding that operational complexities may hinder well–designed provider governance models, unless governance reflects country-specific realities. This commentary builds on the discussion by Saltman and Duran, and argues that the concept of governance needs to be clearly defined and operationalized in order to be helpful for policy debate as well as for the development of an applicable framework for performance improvement. It provides a working definition of governance and includes a reflection on the prevailing cultural norms in an organization or society upon which any governance needs to be build. It proposes to explore whether the “evidence-based governance” concept can be introduced to generate knowledge about innovative and effective governance models, and concludes that studies similar to the one by Saltman and Duran can inform this debate.

Full Text Available WTO Government Procurement Agreement (GPA was designed to liberalize and expand trade in government procurement. Revised GPA was implemented in 1996 and the latest revision was completed (but not yet implemented in 2012, but as a plurilateral agreement. Since the end of the UR, there has been attempts by various WTO members to liberalize trade in the government procurement market? through an expansion of Parties who are signatories to GPA, and through a negotiated agreement on transparency in government procurement. The attempt to expand the Parties who are signatories to the GPA - attempt to increase the width of the coverage of the agreement - has been somewhat successful, but I argue that the goal should be to further liberate the government procurement markets of the current Party members - to reduce thresholds and other barriers which limit market access even to other GPA members, in other words, to increase the depth of coverage. Taking cue from Korea's FTA, I propose a two-level liberalization of the government procurement market under the GPA: A "light" level which would be the same as the current level of liberalization; and a "deep" level with lower thresholds and less exemptions. I argue that, as seen in Korea, with FTAs, many GPA Parties already have multiple levels of liberalization (i.e, spaghetti-bowl effect of FTAs, but by limiting the levels of liberalization to two, we can seek the best of deep liberalization but reduce the spaghetti-bowl effect.

Polycentrism in Global Health Governance Scholarship

Science.gov (United States)

Tosun, Jale

2018-01-01

Drawing on an in-depth analysis of eight global health networks, a recent essay in this journal argued that global health networks face four challenges to their effectiveness: problem definition, positioning, coalition-building, and governance. While sharing the argument of the essay concerned, in this commentary, we argue that these analytical concepts can be used to explicate a concept that has implicitly been used in global health governance scholarship for quite a few years. While already prominent in the discussion of climate change governance, for instance, global health governance scholarship could make progress by looking at global health governance as being polycentric. Concisely, polycentric forms of governance mix scales, mechanisms, and actors. Drawing on the essay, we propose a polycentric approach to the study of global health governance that incorporates coalitionbuilding tactics, internal governance and global political priority as explanatory factors.

However, effective vaccine supply chains that ensure an uninterrupted supply of vaccines are pivotal to attaining universal access to life-saving vaccines and sustainable development. The introduction of new vaccines puts a strain on supply chains; South Africa (SA is no exception, as there are indications of vaccine stock-outs in clinics. Objective. To establish the status of vaccine availability and associated factors in government health facilities of Tshwane Health District in Gauteng Province, SA. Methods. A cross-sectional study was conducted in a sample of randomly selected government clinics in the Tshwane health district of Gauteng Province. Data were collected using a structured measurement instrument in participating clinics. Data were analysed using Excel-based software (Microsoft, USA. Results. A total of 31 clinics participated. In the preceding 12 months, clinics had experienced vaccine stock-outs, especially of the three newer vaccines: pneumococcal conjugate vaccine, rotavirus and Pentaxim. These were also out of stock for a long duration; for over 2 weeks in a majority of clinics. The causes of vaccine stock-outs were: poor management of stock, district depot out of stock, unreliable deliveries, lack of pharmacy assistants and limited fridge capacity. Further burdening the situation is the ineffective emergency-ordering system. Conclusion. Significant shortages of vaccines, which are essential drugs, occur in Tshwane government clinics. Vaccine supply chain issues and vaccine shortages should be treated as a priority at all levels of the healthcare system; therefore, a similar study should be conducted at national level. It is recommended that the vaccine supply chain should

Full Text Available Abstract Introduction 5S is the stepping stone for many quality improvement concepts and its roots date back to 16th century. When successfully implemented 5S gives many benefits to the organization as well as its stakeholders. Though 5S itself has a tool to sustain most of the organizations find it difficult to sustain the 5S practice over the time. Therefore the objective of this study was to find out the factors contributing to sustainability of 5S programmes in Government Hospitals in RDHS area Kurunegala. Methodology This study was a descriptive cross sectional study with two components. First component was to identify the 5S sustaining hospitals from not sustaining hospitals by validated evaluation sheet. Second component was to determine the factors contributing to sustainability of 5S programmes in selected study setting. Self-administrated questionnaire was used for this purpose. Total study population was 543 employees of all the categories of hospital staff. Calculated sample size was 422 and 375 were responded to the questionnaire giving response rate of 88.9. Results The study revealed that the implemented 5S programmes were sustaining in eight hospitals out of ten i.e. sustaining rate was 80. When it considered the degree of sustainability 50 of the selected hospitals reported more than 70 sustainability. This was considered as favourable trend in government health sector in healthcare quality point of view. Ten factors were studied as contributing factors for the 5S sustainability. Socio- demographic factors were also considered. Those ten factors were top management commitment leadership of the organization commitment of middle amp frontline managers commitment amp satisfaction of employees training amp changing attitude of employees motivation of employees organizational culture group cohesiveness community participation and customer satisfaction.

2015-03-01

Full Text Available Effective corporate governance is a key element in achieving long-term success for any company. The codes of conduct that corporate governance adopts directly determine the sustainability of business activities. With this in mind, this paper aims to demonstrate the results of research that identifies a set of key indicators of corporate governance performance. The presented research is quantitative. In order to identify key performance indicators, factor analysis was employed. It was found that corporate governance performance is influenced by two factors. For the first factor, the relationship between corporate governance and stakeholders is measured by key indicators: percentage of women within CG, contributions to political parties, politicians and related institutions and number of complaints received from stakeholders. The second factor, strategy & compliance, is generated from the following: percentage of strategic objectives met and total number of sanctions for breaching the law. This research aims to assist both academic and corporate practitioners who want to improve corporate governance performance and, through the use of key performance indicators, support the transparency and sustainability of their business.

Full Text Available We analyse a panel data set covering the years 2001 to 2005 and comprised of a stratified sample of A, AB and AH non financial companies listed on China’s Shanghai and Shenzhen stock exchanges to provide empirical evidence on the influence of corporate control and governance characteristics on the quality and independence of corporate decision making in these companies. The characteristics considered are the level of concentration in and type of ownership of the companies, particularly high levels of government and foreign ownership, and the composition (expertise and size of the companies’ two boards. Performance outcomes, and by association the quality and independence of corporate policy decisions, are measured in the form of firm bad debt to accounts receivable ratio (BD/AR. We find that for our sample firms’ concentration of ownership, including state and foreign ownership, and board size and independence are significant factors in determining the levels of the bad debt ratio.

Zhang, Yingqi; Hubbard, Susan; Finsterle, Stefan

2011-01-01

The objective of this paper was to provide new insights into processes affecting riverbank filtration (RBF). We consider a system with an inflatable dam installed for enhancing water production from downstream collector wells. Using a numerical model, we investigate the impact of groundwater pumping and dam operation on the hydrodynamics in the aquifer and water production. We focus our study on two processes that potentially limit water production of an RBF system: the development of an unsaturated zone and riverbed clogging. We quantify river clogging by calibrating a time-dependent riverbed permeability function based on knowledge of pumping rate, river stage, and temperature. The dynamics of the estimated riverbed permeability reflects clogging and scouring mechanisms. Our results indicate that (1) riverbed permeability is the dominant factor affecting infiltration needed for sustainable RBF production; (2) dam operation can influence pumping efficiency and prevent the development of an unsaturated zone beneath the riverbed only under conditions of sufficient riverbed permeability; (3) slow river velocity, caused by dam raising during summer months, may lead to sedimentation and deposition of fine-grained material within the riverbed, which may clog the riverbed, limiting recharge to the collector wells and contributing to the development of an unsaturated zone beneath the riverbed; and (4) higher river flow velocities, caused by dam lowering during winter storms, scour the riverbed and thus increase its permeability. These insights can be used as the basis for developing sustainable water management of a RBF system. Journal compilation © 2010 National Ground Water Association.

Full Text Available Integration of Landsat images and multisource data using spatial statistical analysis and geographical detector models can reveal the individual and interactive influences of anthropogenic activities and ecological factors on concentrations of atmospheric particulate matter less than 2.5 microns in diameter (PM2.5. This approach has been used in many studies to estimate biomass and forest disturbance patterns and to monitor carbon sinks. However, the approach has rarely been used to comprehensively analyze the individual and interactive influences of anthropogenic factors (e.g., population density, impervious surface percentage and ecological factors (e.g., canopy density, stand age, and elevation on PM2.5 concentrations. To do this, we used Landsat-8 images and meteorological data to retrieve quantitative data on the concentrations of particulates (PM2.5, then integrated a forest management planning inventory (FMPI, population density distribution data, meteorological data, and topographic data in a Geographic Information System database, and applied a spatial statistical analysis model to identify aggregated areas (hot spots and cold spots of particulates in the urban area of Jinjiang city, China. A geographical detector model was used to analyze the individual and interactive influences of anthropogenic and ecological factors on PM2.5 concentrations. We found that particulate concentration hot spots are mainly distributed in urban centers and suburbs, while cold spots are mainly distributed in the suburbs and exurban region. Elevation was the dominant individual factor affecting PM2.5 concentrations, followed by dominant tree species and meteorological factors. A combination of human activities (e.g., population density, impervious surface percentage and multiple ecological factors caused the dominant interactive effects, resulting in increased PM2.5 concentrations. Our study suggests that human activities and multiple ecological factors

A certain level of public support for smoke-free environments is a prerequisite for adoption and enforcement of policies and can be used as an indicator of readiness for legislative action. This study assessed support for comprehensive smoke-free policies in a range of settings such as hotels and colleges among government workers in China and identified factors associated with support for smoke-free policies. Understanding the extent to which government workers, a large segment of the working population in China, report a smoke-free workplace and support for smoke-free policies may be important indicators of readiness for strengthened policies given their role in formulating, implementing and enforcing regulations. Data were from an evaluation of the Tobacco Free Cities initiative of Emory University's Global Health Institute-China Tobacco Control Partnership. Self-administered surveys were completed by 6,646 workers in 160 government agencies in six Chinese cities. Multivariate logistic regression was used to identify factors associated with support for smoke-free worksites, bars, hotels, and colleges. Over half (54.6%) of participants were male. A large percentage of the male workers smoked (45.9%,) whereas very few women did (1.9%). Fewer than 50% of government workers reported smoke-free policies at work, with 19.0% reporting that smoking is allowed anywhere. Support for smoke-free policies was generally very high, with the lowest levels of support for smoke-free bars (79.0%) and hotels (82.3%), higher levels of support for restaurants (90.0%) and worksites (93.0%), and above 95% support for hospitals, schools, colleges, public transportation and religious settings. Knowledge of the harmfulness of secondhand smoke was positively associated with support for smoke-free policies. Stricter worksite smoking policies were associated with support for smoke-free workplaces and bars, but not hotels and colleges. Women and nonsmokers were more supportive of smoke

Complex relationship between groundwater velocity and concentration of radioactive contaminants

This paper uses the results from the Multi-component Mass Transport model to examine the complex interrelationship between groundwater velocity and contaminant dispersion, decay, and retardation with regard to their influence on the contaminant concentration distribution as it travels through the geosphere to the biosphere. The rate of transport of contaminants through the geosphere is governed by groundwater velocity, leach rate, and contaminant retardation. The dominant characteristics of the contaminant concentration distribution are inherited during leaching and modified during transport by dilution, dispersion and decay. For a hypothetical non-decaying, non-dispersing contaminant with no retardation properties, the shape of the source term distribution is governed by the groundwater velocity (dilution) and leach rate. This distribution remains unchanged throughout transport. Under actual conditions, however, dispersion, decay and retardation modify the concentration distribution during both leaching and transport. The amount of dispersion is determined by the distance traveled, but it does have a greater peak-reducing influence on spiked distributions than square-shaped distributions. Decay acts as an overall scaling factor on the concentration distribution. Retardation alters the contaminant travel time and therefore indirectly influences the amount of dilution, dispersion and decay. Simple relationships between individual parameters and groundwater velocity as they influence peak concentration do not exist. For those cases where the source term is not solubility-limited and flow past the waste is independent of regional hydrologic conditions, a threshold concentration occurs at a specific groundwater velocity where the effects of dilution balance those of dispersion and decay

GIS has wider and wider applications. The application in the field of administrative management and assistant decision-making have formed a specific research area--the government GIS. As an information industry with great sociality, GIS and its development are influenced by many technical factors and social factors. As for the government GIS in China, the social factors often play a more important role in it. A description of the current development status of the government GIS, both in China and abroad, was made in this paper. After the description, researchers pointed out the deficiency of Chinese government GIS. On the basis of this, the rational suggestion of government GIS in China were put forward at last.

A 4 year study surveyed 131 lakes across New York State beginning in 2003 to improve our understanding of mercury and gather information from previously untested waters. Our study focused on largemouth and smallmouth bass, walleye and yellow perch, common piscivorous fish shown to accumulate high mercury concentrations and species important to local fisheries. Fish from Adirondack and Catskill Forest Preserve lakes generally had higher mercury concentrations than those from lakes in other areas of the state. Variability between nearby individual lakes was observed, and could be due to differences in water chemistry, lake productivity or the abundance of wetlands in the watershed. We found the following factors impact mercury bioaccumulation: fish length, lake pH, specific conductivity, chlorophyll a, mercury concentration in the water, presence of an outlet dam and amount of contiguous wetlands. - Lake water chemistry variables, dams, and wetlands play major roles in determining fish mercury concentrations

241-SY-101 strain concentration factor development via nonlinear analysis. Volume 1 of 1

International Nuclear Information System (INIS)

1997-01-01

The 241-SY-101 waste storage tank at the Hanford-Site has been known to accumulate and release significant quantities of hydrogen gas. An analysis was performed to assess the tank's structural integrity when subjected to postulated hydrogen deflagration loads. The analysis addressed many nonlinearities and appealed to a strain-based failure criteria. The model used to predict the global response of the tank was not refined enough to confidently predict local peak strains. Strain concentration factors were applied at structural discontinuities that were based on steel-lined reinforced-concrete containment studies. The discontinuities included large penetrations, small penetrations, springline geometries, stud/liner connections, and the 1/2 inch to 3/8 inch liner thickness transition. The only tank specific strain concentration factor applied in the evaluation was for the 1/2 inch to 3/8 inch liner thickness change in the dome. Review of the tank drawings reveals the possibility that a 4 inches Sch. 40 pipe penetrates the dome thickness transition region. It is not obvious how to combine the strain concentration factors for a small penetration with that of a thickness transition to arrive at a composite strain concentration factor. It is the goal of this effort to make an approximate determination of the relative significance of the 4 inch penetration and the 1/2 inch to 3/8 inch thickness transition in the 241-SY-101 dome geometry. This is accomplished by performing a parametric study with three general finite-element models. The first represents the thickness transition only, the second represents a 4 inch penetration only, and the third combines the thickness transition with a penetration model

Theoretical interpretation of e-government implementation challenges in South Africa: A case study of a selected provincial government

Full Text Available This paper discusses factors influencing e-Government initiatives by African Governments to improve services to their citizens, businesses and their constituent. It further discusses, as a socially constructed phenomenon, the degree of readiness of governments to implement e-Government initiatives to improve services. The discussion uses Actor Network Theory (ANT and in particular the concepts of moments of translation and irreversibility as a lens through which to understand and interpret the social phenomenon. Although a number of e-Government researchers have argued that strong leadership and clear vision is required to implement e-Government initiatives, the view is that Governments have continuously failed to achieve the intended results. E-Government potentials and benefits which are well documented in Information Systems and e-Government research literature have not been realised by governments due to limited capabilities in the administration of the public service. The study applied a deductive approach where semi-structured interviews were used for data collection in a selected Provincial Government in South Africa. The outcome is a general framework to determine the readiness of South Africa government and generally, African governments for e-Government initiatives to achieve the intended results.

Sample pre-concentration with high enrichment factors at a fixed location in paper-based microfluidic devices.

Yeh, Shih-Hao; Chou, Kuang-Hua; Yang, Ruey-Jen

2016-03-07

The lack of sensitivity is a major problem among microfluidic paper-based analytical devices (μPADs) for early disease detection and diagnosis. Accordingly, the present study presents a method for improving the enrichment factor of low-concentration biomarkers by using shallow paper-based channels realized through a double-sided wax-printing process. In addition, the enrichment factor is further enhanced by exploiting the ion concentration polarization (ICP) effect on the cathodic side of the nanoporous membrane, in which a stationary sample plug is obtained. The occurrence of ICP on the shallow-channel μPAD is confirmed by measuring the current-voltage response as the external voltage is increased from 0 to 210 V (or the field strength from 0 to 1.05 × 10(4) V m(-1)) over 600 s. In addition, to the best of our knowledge, the electroosmotic flow (EOF) speed on the μPAD fabricated with a wax-channel is measured for the first time using a current monitoring method. The experimental results show that for a fluorescein sample, the concentration factor is increased from 130-fold in a conventional full-thickness paper channel to 944-fold in the proposed shallow channel. Furthermore, for a fluorescein isothiocyanate-labeled bovine serum albumin (FITC-BSA) sample, the proposed shallow-channel μPAD achieves an 835-fold improvement in the concentration factor. The concentration technique presented here provides a novel strategy for enhancing the detection sensitivity of μPAD applications.

The development of platelet-rich fibrin (PRF) drastically simplified the preparation procedure of platelet-concentrated biomaterials, such as platelet-rich plasma (PRP), and facilitated their clinical application. PRF's clinical effectiveness has often been demonstrated in pre-clinical and clinical studies; however, it is still controversial whether growth factors are significantly concentrated in PRF preparations to facilitate wound healing and tissue regeneration. To address this matter, we performed a comparative study of growth factor contents in PRP and its derivatives, such as advanced PRF (A-PRF) and concentrated growth factors (CGF). PRP and its derivatives were prepared from the same peripheral blood samples collected from healthy donors. A-PRF and CGF preparations were homogenized and centrifuged to produce extracts. Platelet and white blood cell counts in A-PRF and CGF preparations were determined by subtracting those counts in red blood cell fractions, supernatant acellular serum fractions, and A-PRF/CGF exudate fractions from those counts of whole blood samples. Concentrations of growth factors (TGF-β1, PDGF-BB, VEGF) and pro-inflammatory cytokines (IL-1β, IL-6) were determined using ELISA kits. Compared to PRP preparations, both A-PRF and CGF extracts contained compatible or higher levels of platelets and platelet-derived growth factors. In a cell proliferation assay, both A-PRF and CGF extracts significantly stimulated the proliferation of human periosteal cells without significant reduction at higher doses. These data clearly demonstrate that both A-PRF and CGF preparations contain significant amounts of growth factors capable of stimulating periosteal cell proliferation, suggesting that A-PRF and CGF preparations function not only as a scaffolding material but also as a reservoir to deliver certain growth factors at the site of application.

Do Policy Networks lead to Network Governing?

DEFF Research Database (Denmark)

Damgaard, Bodil

This paper challenges the notion that creation of local policy networks necessarily leads to network governing. Through actor-centred case studies in the area of municipally implemented employment policy in Denmark it was found that the local governing mode is determined mainly by the municipality......’s approach to local co-governing as well as by the capacity and interest of key private actors. It is argued that national legislation requesting the creation of local policy networks was not enough to assure network governing and the case studies show that local policy networks may subsist also under...... hierarchical governing modes. Reasons why hierarchical governing modes prevail over network governing in some settings are identified pointing to both actor borne and structural factors. Output indicators of the four cases do not show that a particular governing mode is more efficient in its employment policy...

Tax reform in the Lula government: continuity and fiscal injustice

Directory of Open Access Journals (Sweden)

Alexandrine Brami-Celentano

2007-04-01

Full Text Available The tax reform proposed by the Lula government in 2003, quickly approved by Congress, remained at the limits of the proposals of the previous government of President Fernando Henrique Cardoso and his Social Democratic party (PSDB, inspired by neoliberal ideology. The small advances in reducing regressivity, such as exemptions for basic consumer products, have not altered the role of the tax structure in the concentration of wealth, with a predominance of indirect taxes and their regressive effects. Taxation has deserved little attention in the broad debate about social policies in Brazil, which concentrates on the allocation of public expenses and the efficiency of spending, without proper attention to the role of the tax structure in the concentration of income and wealth in the country. The article presents the regressive profile of the Brazilian tax structure, preserved by the reform of 2003 and discusses the neoliberal agenda that guides the initiatives of the Lula government in this field.

Identifying environmental and geochemical variables governing metal concentrations in a stream draining headwaters in NW Spain

Highlights: • All metals occur in association with suspended sediment. • DOC and SS appeared to influence the partitioning of metals. • The SS was a good predictor of particulate metal levels. • The most important variable to explain storm-event K D for Al and Fe is DOC. • Enrichment factor values suggest a natural origin for the particulate metals. - Abstract: Headwater stream, draining from a rural catchment in NW Spain, was sampled during baseflow and storm-event conditions to investigate the temporal variability in dissolved and particulate Al, Fe, Mn, Cu and Zn concentrations and the role of discharge (Q), pH, dissolved organic carbon (DOC) and suspended sediment (SS) in the transport of dissolved and particulate metals. Under baseflow and storm-event conditions, concentrations of the five metals were highly variable. The results of this study reveal that all metal concentrations are correlated with SS. DOC and SS appeared to influence both the metal concentrations and the partitioning of metals between dissolved and particulate. The SS was a good predictor of particulate metal levels. Distribution coefficients (K D ) were similar between metals (4.72–6.55) and did not change significantly as a function of discharge regime. Stepwise multiple linear regression analysis reveals that the most important variable to explain storm-event K D for Al and Fe is DOC. The positive relationships found between metals, in each fraction, indicate that these elements mainly come from the same source. Metal concentrations in the stream were relatively low

Soil transmitted helminth infections are among the most common human infections. They are distributed throughout the world with high prevalence rates in tropical and sub-tropical countries mainly because of lack of adequate sanitary facilities, inappropriate waste disposal systems, lack of safe water supply, and low socio-economic status. A comparative cross sectional study was conducted from December 2011 to June 2012 to determine and assess the prevalence of soil transmitted helminths and their associated factors among government and private primary school children. Stool samples were collected from 369 randomly selected children and examined microscopically for eggs of soil transmitted helminth following McMaster techniques. Soil samples were collected from different parts of the school compound and microscopic examination was performed for eggs of the helminths using sodium nitrate flotation technique. The overall prevalence rate of soil transmitted helminth infections in private and government schools was 20.9% and 53.5% respectively. T. trichiura was the most common soil transmitted helminth in both schools while hookworm infections were identified in government school students only. Type of school and sex were significantly associated with soil transmitted helminth. Soil contamination rate of the school compounds was 11.25% with predominant parasites of A. lumbricoides. Higher prevalence of soil transmitted helminth infection was found among government school students. Thus, more focus, on personal hygiene and sanitary facilities, should be given to children going to government schools.

In this study, uptake of Ra from soil into the edible fruit of the wild passionfruit species Passiflora foetida was investigated, using selective extraction from the soil samples. A wide range of environmental exposure conditions were represented by the locations that were sampled, including both natural soils, and soils influenced by past and present uranium mining activities. The bioavailable 226 Ra fraction in soils was found to be a better predictor of 226 Ra fruit activity concentrations than the total soil activity concentration, or any of the other fractions studied. Concentration Factors (CFs) derived using the bioavailable fraction varied by only a factor of 7 between different locations, whereas CFs derived using other fractions and total soil varied by up to two orders of magnitude. CFs were highest for those soils containing the lowest concentrations of Mg, Ca and Ba, and approached a saturation value at higher soil concentrations. This finding suggests that group II elements influence radium uptake, most likely the result of increased pressure on the plant to take up essential nutrient group II elements from soil with the lower concentrations, with Ra being taken up as an analogue element. It is also possible that at higher concentrations of bioavailable Ca and Mg in the soil, these ions will outcompete Ra for adsorption sites in the soil and/or on the root surfaces. The study also shows that 228 Ra can potentially be a significant contributor to ingestion doses and should also be considered when assessing committed effective doses from the ingestion of fruits. -- Highlights: • Fruit and soil samples were taken from wild growing native passionfruit plants. • The sampling locations were on natural and U mining impacted sites. • Sequential extraction of the soil was undertaken. • Radium-226, radium-228 and other key elements were measured. • Concentration factors show the lowest variability in the bioavailable fraction

The US Subseabed Disposal Program has compiled an extensive objective concentration factor and biological half-life data base from the international marine radioecological literature. A microcomputer-based data management system has been implemented to provide statistical and graphical summaries of these data. The data base is constructed in a manner which allows subsets to be sorted using a number of inter-study variables such as organism category, tissue/organ category, geographic location (for in situ studies), and several laboratory-related conditions (e.g., exposure time and exposure concentration). We discuss concentration factor data summaries for many elements. We also discuss summary material for biological half-life data. We discuss the results of our review with the estimates of mean concentration factors provided by the IAEA. It is proposed that this presentation scheme will enable those concerned with predictive assessment of radiation dose in the marine environment to make a more judicious selection of data for a given application. 7 references

At a global level, the relationship between biodiversity importance and capacity to manage it is often assumed to be negative, without much differentiation among the more than 200 countries and territories of the world. We examine this relationship using a database including terrestrial biodiversity, wealth and governance indicators for most countries. From these, principal components analysis was used to construct aggregated indicators at global and regional scales. Wealth, governance, and scientific capacity represent different skills and abilities in relation to biodiversity importance. Our results show that the relationship between biodiversity and the different factors is not simple: in most regions wealth and capacity varies positively with biodiversity, while governance vary negatively with biodiversity. However, these trends, to a certain extent, are concentrated in certain groups of nations and outlier countries. We discuss our results in the context of collaboration and joint efforts among biodiversity-rich countries and foreign agencies.

Soil samples were collected on Polder 32 in the coastal zone of SW Bangladesh in wet (October) and dry (May) seasons from 2013-2017 and analyzed to characterize the problems of soil salinization and arsenic contamination and identify their causes. Soils are entisols formed from recently deposited, predominantly silt-sized sediments with low carbon concentrations typical of the local mangrove forests. Soluble (DI extract) arsenic concentrations were below the Government of Bangladesh limit of 50 ppb for drinking water. Soil acidity and extract arsenic concentrations exhibit spatial variation but no consistent trends. In October soil extract As is higher and S and pH are lower than in May. These observations suggest that wet season rainwater oxidizes pyrite, reducing soil S and releasing H+, causing pH to decrease. Released iron is oxidized to form Hydrous Ferric Oxyhydroxides (HFOs), which sorb As and increase extractable As in wet season soils. Changes in pH are small due to pH buffering by soil carbonates. Soil and rice paddy water salinities are consistently higher in May than October, reaching levels in May that reduce rice yields. Rice grown in paddies should be unaffected by salt concentrations in the wet season, while arsenic concentrations in soil may be high enough to cause unsafe As levels in produced rice.

The effect of different climatic factors on radiocarbon concentration in the Earth atmosphere is analyzed by modelling the exchange radiocarbon system. It is supposed that the exchange system consists of four reservoirs: long-lived surface vegetation and its remnants, the atmosphere, surface layer of the World ocean. It is shown that the variations of the ocean temperature and the variations in CO 2 amount in the atmosphere connected with it do not affect the atmosphere radiocarbon concentration. Variations in the square of sea ice on the time scale of >=1000 years could bring about variations in the 14 C concentration with the amplitude up to 1%. 14 C concentration in the atmosphere in the icing maximum 18 thousands of years ago was 7% higher than present concentration [ru

We analyzed and compared the difference in sinapine concentration in rapeseed meal between the filamentous fungus, Trametes sp 48424, and the yeast, Saccharomyces cerevisiae, in both liquid and solid-state fermentation. During liquid and solid-state fermentation by Trametes sp 48424, the sinapine concentration decreased significantly. In contrast, the liquid and solid-state fermentation process by Saccharomyces cerevisiae just slightly decreased the sinapine concentration (P ≤ 0.05). After the solid-state fermented samples were dried, the concentration of sinapine in rapeseed meal decreased significantly in Saccharomyces cerevisiae. Based on the measurement of laccase activity, we observed that laccase induced the decrease in the concentration of sinapine during fermentation with Trametes sp 48424. In order to eliminate the influence of microorganisms and the metabolites produced during fermentation, high moisture rapeseed meal and the original rapeseed meal were dried at 90°C and 105°C, respectively. During drying, the concentration of sinapine in high moisture rapeseed meal decreased rapidly and we obtained a high correlation coefficient between the concentration of sinapine and loss of moisture. Our results suggest that drying and enzymes, especially laccase that is produced during the solid-state fermentation process, may be the main factors that affect the concentration of sinapine in rapeseed meal.

Cardiovascular diseases are among the most important sources of mortality and morbidity, and have a high disease burden. There are some major well-known risk factors, which contribute to the development of these diseases. Occupational stress is caused due to imbalance between job demands and individual's ability, and it has been implicated as an etiology for cardiovascular diseases. This study was conducted to evaluate the cardiovascular risk factors and different dimensions of occupational stress in high-ranking government officials, comparing an age and sex-matched group of office workers with them. We invited 90 high-ranking officials who managed the main governmental offices in a city, and 90 age and sex-matched office workers. The subjects were required to fill the occupational role questionnaire (Osipow) which evaluated their personal and medical history as well as occupational stress. Then, we performed physical examination and laboratory tests to check for cardiovascular risk factors. Finally, the frequency of cardiovascular risk factors and occupational stress of two groups were compared. High-ranking officials in our study had less work experience in their current jobs and smoked fewer pack-years of cigarette, but they had higher waist and hip circumference, higher triglyceride level, more stress from role overload and responsibility, and higher total stress score. Our group of office workers had more occupational stress because of role ambiguity and insufficiency, but their overall job stress was less than officials. The officials have higher scores in some dimensions of occupational stress and higher overall stress score. Some cardiovascular risk factors were also more frequent in managers.

Campus Sustainability is an effort that integrates environmentally sustainable practices into institutional practices. A successful transition to a sustainable campus requires the involvement of the university community; the administration, academics departments (faculty and students), researchers and he local community. Our research seeks to identify Critical Success Factors (CSFs) of university governance that contribute to the success in implementing Sustainable Campus Operation (SCO) initiatives. The common CSFs have been identified from 22 published and unpublished articles, conference proceedings, university reports, books, and website documents. The CSFs are mapped and ranked based on the frequency of the identified CSFs. 23 CSFs of SCO have been identified through this research. This research revealed that the CSF that contributes the highest frequency as indicated by most researchers is “developing network with external parties for gaining consensus and commitment”. By identifying these CSFs, this research will help assist universities in successfully plan and implement their SCO initiatives.

Objective: Toxic heavy metals are released to the environment constantly from unregulated electronic waste (e-waste) recycling in Guiyu, China, and thus may contribute to the elevation of mercury (Hg) and other heavy metals levels in human hair. We aimed to investigate concentrations of mercury in hair from Guiyu and potential risk factors and compared them with those from a control area where no e-waste processing occurs. Methods: A total of 285 human hair samples were collected from three villages (including Beilin, Xianma, and Huamei) of Guiyu (n=205) and the control area, Jinping district of Shantou city (n=80). All the volunteers were administered a questionnaire regarding socio-demographic characteristics and other possible factors contributed to hair mercury concentration. Hair mercury concentration was analyzed by hydride generation atomic fluorescence spectrometry (AFS). Results: Our results suggested that hair mercury concentrations in volunteers of Guiyu (median, 0.99; range, 0.18–3.98 μg/g) were significantly higher than those of Jinping (median, 0.59; range, 0.12–1.63 μg/g). We also observed a higher over-limit ratio (>1 μg/g according to USEPA) in Guiyu than in Jinping (48.29% vs. 11.25%, P<0.001). Logistic regression model showed that the variables of living house also served as an e-waste workshop, work related to e-waste, family income, time of residence in Guiyu, the distance between home and waste incineration, and fish intake were associated with hair mercury concentration. After multiple stepwise regression analysis, in the Guiyu samples, hair mercury concentration was found positively associated with the time residence in Guiyu (β=0.299, P<0.001), and frequency of shellfish intake (β=0.184, P=0.016); and negatively associated with the distance between home and waste incineration (β=−0.190, P=0.015) and whether house also served as e-waste workshop (β=−0.278, P=0.001). Conclusions: This study investigated human mercury exposure

Strategic governance: Addressing neonatal mortality in situations of political instability and weak governance.

Science.gov (United States)

Wise, Paul H; Darmstadt, Gary L

2015-08-01

Neonatal mortality is increasingly concentrated globally in situations of conflict and political instability. In 1991, countries with high levels of political instability accounted for approximately 10% of all neonatal deaths worldwide; in 2013, this figure had grown to 31%. This has generated a "grand divergence" between those countries showing progress in neonatal mortality reduction compared to those lagging behind. We present new analyses demonstrating associations of neonatal mortality with political instability (r = 0.55) and poor governance (r = 0.70). However, heterogeneity in these relationships suggests that progress is possible in addressing neonatal mortality even in the midst of political instability and poor governance. In order to address neonatal mortality more effectively in such situations, we must better understand how specific elements of "strategic governance"--the minimal conditions of political stability and governance required for health service implementation--can be leveraged for successful introduction of specific health services. Thus, a more strategic approach to policy and program implementation in situations of conflict and political instability could lead to major accelerations in neonatal mortality reduction globally. However, this will require new cross-disciplinary collaborations among public health professionals, political scientists, and country actors. Copyright © 2015 The Authors. Published by Elsevier Inc.

Wan Nasrudin Wan Asma

2017-01-01

Full Text Available The aim of this paper is to investigate the determinants of firm’s auditor choice in Malaysia in respect of their corporate governance mechanisms. A logit regression model was developed to test the impact of firms’ internal corporate governance mechanism on auditor choice decisions made by public listed companies listed on main board of Bursa Malaysia from year 2006 to 2015. Five variables are used to proxy for firm’s internal corporate mechanism which are the ownership concentration, the duality of CEO and chairman of BOD, the size of audit committee, the size of BOD and the number of independent directors on the board. All auditors in Malaysia were classified into Big Four and non-Big Four, assuming Big Four auditors can provide higher quality audit services. The final result show that firms with less concentrated ownership, with larger size of audit committee, larger size of the BOD, with lower proportion of independent directors on the board, or in which CEO and BOD’s chairman are not the same person are more likely to hire a high-quality auditor. Hence, it suggests that when benefits from lowering capital raising costs are trivial, firms with good corporate governance mechanism are prone to choose a high-quality auditor.

Factors influencing concentrations of dissolved gaseous mercury (DGM) and total mercury (TM) in an artificial reservoir

Ahn, Myung-Chan; Kim, Bomchul; Holsen, Thomas M.; Yi, Seung-Muk; Han, Young-Ji

2010-01-01

The effects of various factors including turbidity, pH, DOC, temperature, and solar radiation on the concentrations of total mercury (TM) and dissolved gaseous mercury (DGM) were investigated in an artificial reservoir in Korea. Episodic total mercury accumulation events occurred during the rainy season as turbidity increased, indicating that the TM concentration was not controlled by direct atmospheric deposition. The DGM concentration in surface water ranged from 3.6 to 160 pg/L, having a maximum in summer and minimum in winter. While in most previous studies DGM was controlled primarily by a photo-reduction process, DGM concentrations tracked the amount of solar radiation only in winter when the water temperature was fairly low in this study. During the other seasons microbial transformation seemed to play an important role in reducing Hg(II) to Hg(0). DGM increased as dissolved organic carbon (DOC) concentration increased (p-value < 0.01) while it increased with a decrease of pH (p-value < 0.01). - Long-term in-situ monitoring of TM and DGM concentrations with various factors was executed in a large artificial reservoir in this study.

Beneficial Effects of Concentrated Growth Factors and Resveratrol on Human Osteoblasts In Vitro Treated with Bisphosphonates

2018-01-01

Full Text Available Bisphosphonates are primary pharmacological agents against osteoclast-mediated bone loss and widely used in the clinical practice for prevention and treatment of a variety of skeletal conditions, such as low bone density and osteogenesis imperfecta, and pathologies, such as osteoporosis, malignancies metastatic to bone, Paget disease of bone, multiple myeloma, and hypercalcemia of malignancy. However, long-term bisphosphonate treatment is associated with pathologic conditions including osteonecrosis of the jaw, named BRONJ, which impaired bone regeneration process. Clinical management of BRONJ is controversy and one recent approach is the use of platelet concentrates, such as Concentrated Growth Factors, alone or together with biomaterials or antioxidants molecules, such as resveratrol. The aim of the present study was to investigate the in vitro effects of Concentrated Growth Factors and/or resveratrol on the proliferation and differentiation of human osteoblasts, treated or not with bisphosphonates. Human osteoblasts were stimulated for 3 days in complete medium and for 21 days in mineralization medium. At the end of the experimental period, the in vitro effect on osteoblast proliferation and differentiation was evaluated using different techniques such as MTT, ELISA for the quantification/detection of osteoprotegerin and bone morphogenetic protein-2, immunohistochemistry for sirtuin 1 and collagen type I, and the Alizarin Red S staining for the rate of mineralization. Results obtained showed that Concentrated Growth Factors and/or resveratrol significantly increased osteoblast proliferation and differentiation and that the cotreatment with Concentrated Growth Factors and resveratrol had a protective role on osteoblasts treated with bisphosphonates. In conclusion, these data suggest that this approach could be promised in the clinical management of BRONJ.

2016-03-01

Full Text Available Assessing the achievement of Indonesian government institutions in implementing e-government has been conducted since around a decade ago. Several national assessments are available with almost the same ranking results. There is an agreement that the ultimate goal of e-government implementation is to achieve good government governance (GGG, while success stories of e-government require good governance practices. This study explored the correlation between e-government achievement and GGG achievement in Indonesia. Spearman’s rank correlation was used to characterize the relationship strength between e-government assessment results and good governance assessment results. The data were collected from institutions that participated in e-government and good governance assessments. The results showed that the correlation between these two entities is not very strong. Most cases showed that e-government implementation and the achievement of good governance have only a moderate positive correlation and none of the studied cases indicated a significant connection. This result can be attributed to the lack of emphasis on goals achievement in the assessments. Thus, it is recommended that future Indonesian e-government assessments should involve impact indicators.

Corporate Governance in Banks and its Impact on Risk and Performance: Review of Literature on the Selected Governance Mechanisms

2014-09-01

Full Text Available Corporate governance is viewed as an important, essential, and most significant factor for well-functioning of firms. Recent academic work and policy analyses have given insight into the governance problems in banks exposed to the financial crisis and suggest possible solutions. This paper begins by explaining the importance of corporate governance and its impact on risk taking and bank performance based on the theoretical background relevant to the corporate governance of banks. I combine the literature that looks at three areas of governance: ownership structure; board structure; and risk management, with the literature on risk-taking and performance effects in order to better assess the weight of the impact that these governance mechanisms have on both performance and risk. The paper concludes by highlighting the areas where further research is needed.

Tributyltin (TBT), which has been widely used as an antifouling agent in paints, is a common environmental pollutant. Although the toxicity of high-dose TBT has been extensively reported, the effects of low concentrations of TBT are relatively less well studied. We have previously reported that low-concentration TBT decreases α-amino-3-hydroxy-5-methylisoxazole-4-propionic acid (AMPA)-type glutamate receptor subunit 2 ( GluR2 ) expression in cortical neurons and enhances neuronal vulnerability to glutamate. However, the mechanism of this TBT-induced GluR2 decrease remains unknown. Therefore, we examined the effects of TBT on the activity of transcription factors that control GluR2 expression. Exposure of primary cortical neurons to 20 nM TBT for 3 h to 9 days resulted in a decrease in GluR2 mRNA expression. Moreover, TBT inhibited the DNA binding activity of nuclear respiratory factor-1 (NRF-1), a transcription factor that positively regulates the GluR2 . This result indicates that TBT inhibits the activity of NRF-1 and subsequently decreases GluR2 expression. In addition, 20 nM TBT decreased the expression of genes such as cytochrome c, cytochrome c oxidase (COX) 4, and COX 6c, which are downstream of NRF-1. Our results suggest that NRF-1 inhibition is an important molecular action of the neurotoxicity induced by low-concentration TBT.

Labour pain is distressing and it produces undue side effects both to the mother and the baby. The incidence is high in developing countries like India where the awareness about labour analgesia is still lacking. It is to find out the incidence of labour pain and the influence of various described factors on pain with a comparison between patients admitted in a government set up with a private set up in a south Indian semi-urban area. Two hundred continuous uneventful normal deliveries each in a Government (group G) and a private hospital (group P) were enrolled for the study. The reported pain during labour was noted 6-7 hours after delivery by interacting with the patient. The factors like age of the mother, sex and weight of the baby, literacy, socioeconomic status, the use of oxytocics and analgesia were evaluated. The incidence of severe pain was more in group G (43.5%) than group P (12%). There was no analgesic intervention in 68.5% in group G while it was 13.5% (27/200) in group P. Even among these 27 patients who did not receive analgesics, only three parturients reported severe pain. Even administration of analgesics in a Government set up did not decrease pain to a significant extent. There were richer and more literate patients in group P. Booked cases were less in group G. Logistic regression analyses to find out factors which influenced pain in either group was used. Gravida, analgesic intervention and admission in a Govt. hospital influenced the pain experience of the parturient. There was minimal antenatal preparation in both the groups. There were no post partum complications. Mothers suffered from labour pain to a significant extent and there is an urgent need for awareness about labour analgesia. Primigravida, admission in a Govt. set up and analgesic interventions were the factors which influenced pain than others. Patients admitted in Govt. hospitals suffered more pain with less analgesic intervention possibly due to illiteracy. The increased

Cardiac surgery may cause a serious coagulopathy leading to increased risk of bleeding and transfusion demands. Blood bank products are commonly first line haemostatic intervention, but has been associated with hazardous side effect. Coagulation factor concentrates may be a more efficient, predictable, and potentially a safer treatment, although prospective clinical trials are needed to further explore these hypotheses. This study investigated the haemostatic potential of ex vivo supplementation of coagulation factor concentrates versus blood bank products on blood samples drawn from patients undergoing cardiac surgery. 30 adults were prospectively enrolled (mean age=63.9, females=27%). Ex vivo haemostatic interventions (monotherapy or combinations) were performed in whole blood taken immediately after surgery and two hours postoperatively. Fresh-frozen plasma, platelets, cryoprecipitate, fibrinogen concentrate, prothrombin complex concentrate (PCC), and recombinant FVIIa (rFVIIa) were investigated. The haemostatic effect was evaluated using whole blood thromboelastometry parameters, as well as by thrombin generation. Immediately after surgery the compromised maximum clot firmness was corrected by monotherapy with fibrinogen or platelets or combination therapy with fibrinogen. At two hours postoperatively the coagulation profile was further deranged as illustrated by a prolonged clotting time, a reduced maximum velocity and further diminished maximum clot firmness. The thrombin lagtime was progressively prolonged and both peak thrombin and endogenous thrombin potential were compromised. No monotherapy effectively corrected all haemostatic abnormalities. The most effective combinations were: fibrinogen+rFVIIa or fibrinogen+PCC. Blood bank products were not as effective in the correction of the coagulopathy. Coagulation factor concentrates appear to provide a more optimal haemostasis profile following cardiac surgery compared to blood bank products. Copyright © 2017

2018-04-01

Recent research has advanced understanding of corporate governance of healthcare quality, highlighting the need for future empirical work to develop beyond a focus on board composition to a more detailed exploration of the internal workings of governance that influence board engagement and activities. This paper proposes a conceptual framework to guide empirical research examining the work of board and senior management in governing healthcare quality. To generate this framework, existing conceptual approaches and key constructs influencing effectiveness are identified in the governance literature. Commonalities between governance and team effectiveness literature are mapped and suggest a number of key constructs in the team effectiveness literature are applicable to, but not yet fully explored, within the governance literature. From these we develop a healthcare governance conceptual framework encompassing both literatures, that outlines input and mediating factors influencing governance. The mapping process highlights gaps in research related to board dynamics and external influences that require further investigation. Organizing the multiple complex factors that influence governance of healthcare quality in a conceptual framework brings a new perspective to structuring theory-led research and informing future policy initiatives.

Full Text Available Thirty five Slovak households were selected for an investigation of indoor environmental quality. Measuring of indoor air physical and chemical factors and a questionnaire survey was performed during May 2017. The range of permissible operative temperature was not met in 11% of objects. Relative humidity met the legislative requirements in all monitored homes. Concentrations of total volatile organic compounds (TVOCs were significantly higher in the apartments than in the family houses. The average TVOC levels in the apartments and family houses were 519.7 µg/m3 and 330.2 µg/m3, respectively. Statistical analysis confirmed the effect of indoor air temperature, relative humidity and particulate matter (PM0.5 and PM1 on the levels of TVOCs. Higher TVOC levels were observed also in homes where it is not a common practice to open windows during cleaning activities. Other factors that had a statistically significant effect on concentrations of volatile organic compounds were heating type, attached garage, location of the apartment within residential building (the floor, as well as number of occupants. Higher TVOC concentrations were observed in indoor than outdoor environment, while further analysis showed the significant impact of indoor emission sources on the level of these compounds in buildings. The questionnaire study showed a discrepancy between objective measurement and subjective assessment in the household environment, and pointed to insufficient public awareness about volatile organic compounds (VOCs.

Using reliable information from routine health information systems over time is an important aid to improving health outcomes, tackling disparities, enhancing efficiency, and encouraging innovation. In Ethiopia, routine health information utilization for enhancing performance is poor among health workers, especially at the peripheral levels of health facilities. Therefore, this study aimed to assess routine health information system utilization and associated factors among health workers at government health institutions in East Gojjam Zone, Northwest Ethiopia. An institution based cross-sectional study was conducted at government health institutions of East Gojjam Zone, Northwest Ethiopia from April to May, 2013. A total of 668 health workers were selected from government health institutions, using the cluster sampling technique. Data collected using a standard structured and self-administered questionnaire and an observational checklist were cleaned, coded, and entered into Epi-info version 3.5.3, and transferred into SPSS version 20 for further statistical analysis. Variables with a p-value of less than 0.05 at multiple logistic regression analysis were considered statistically significant factors for the utilization of routine health information systems. The study revealed that 45.8% of the health workers had a good level of routine health information utilization. HMIS training [AOR = 2.72, 95% CI: 1.60, 4.62], good data analysis skills [AOR = 6.40, 95%CI: 3.93, 10.37], supervision [AOR = 2.60, 95% CI: 1.42, 4.75], regular feedback [AOR = 2.20, 95% CI: 1.38, 3.51], and favorable attitude towards health information utilization [AOR = 2.85, 95% CI: 1.78, 4.54] were found significantly associated with a good level of routine health information utilization. More than half of the health workers working at government health institutions of East Gojjam were poor health information users compared with the findings of others studies. HMIS training, data

Factors governing the deep ventilation of the Red Sea

Papadopoulos, Vassilis P.

2015-11-19

A variety of data based on hydrographic measurements, satellite observations, reanalysis databases, and meteorological observations are used to explore the interannual variability and factors governing the deep water formation in the northern Red Sea. Historical and recent hydrographic data consistently indicate that the ventilation of the near-bottom layer in the Red Sea is a robust feature of the thermohaline circulation. Dense water capable to reach the bottom layers of the Red Sea can be regularly produced mostly inside the Gulfs of Aqaba and Suez. Occasionally, during colder than usual winters, deep water formation may also take place over coastal areas in the northernmost end of the open Red Sea just outside the Gulfs of Aqaba and Suez. However, the origin as well as the amount of deep waters exhibit considerable interannual variability depending not only on atmospheric forcing but also on the water circulation over the northern Red Sea. Analysis of several recent winters shows that the strength of the cyclonic gyre prevailing in the northernmost part of the basin can effectively influence the sea surface temperature (SST) and intensify or moderate the winter surface cooling. Upwelling associated with periods of persistent gyre circulation lowers the SST over the northernmost part of the Red Sea and can produce colder than normal winter SST even without extreme heat loss by the sea surface. In addition, the occasional persistence of the cyclonic gyre feeds the surface layers of the northern Red Sea with nutrients, considerably increasing the phytoplankton biomass.

Transfer factors for assessing the dose from radionuclides in agricultural products

Transfer factors to predict the environmental transport of radionuclides through terrestrial foodchains to man were derived from the literature for radionuclides associated with the nuclear fuel cycle. We present updated transfer coefficients to predict the concentration of a radionuclide in cow's milk and other animal products and concentration factors (CF) to predict the concentration in a food or feed crop from that in soil. Where possible we note the variation of the transfer factor with physical and chemical form of the radionuclide and environmental factors, and characterize the distribution and uncertainty in the estimate. The updated transfer factors are compared with those listed in regulatory guides. The new estimates lead to recommended changes (both increases and decreases) in the listed transfer coefficients for milk and meat and to the suggested practice of adopting multiple soil-to-plant CF's that vary with the type of crop and soil in the place of a single generic CF to predict the concentration of a radionuclide in a crop from that in soil. The updated transfer factors will be useful to assess the dose from radionuclides released from nuclear facilities and evaluating compliance with regulations governing the release of radionuclides

Human parvovirus B19 can be transmitted by coagulation factor concentrates and is highly resistant to virucidal methods. To evaluate whether the additional removal of virus by chromatographic methods during the manufacture of high-purity concentrates reduces the risk of B19 transmission, we have prospectively evaluated the rate of anti-B19 seroconversion in two groups of susceptible (anti-B19 negative) hemophiliacs infused with high-purity, heated (pasteurized) or solvent-detergent-treated factor VIII concentrates. Both products infected a relatively high proportion of patients (nine of 20).

Metal ion-containing macromolecules have fundamental roles in essentially all biological processes throughout the evolutionary tree. For example, iron-containing heme is a cofactor in enzyme catalysis and electron transfer and an essential hemoglobin constituent. To meet the intense demand for hemoglobin assembly in red blood cells, the cell type-specific factor GATA-1 activates transcription of Alas2, encoding the rate-limiting enzyme in heme biosynthesis, 5-aminolevulinic acid synthase-2 (ALAS-2). Using genetic editing to unravel mechanisms governing heme biosynthesis, we discovered a GATA factor- and heme-dependent circuit that establishes the erythroid cell transcriptome. CRISPR/Cas9-mediated ablation of two Alas2 intronic cis elements strongly reduces GATA-1-induced Alas2 transcription, heme biosynthesis, and surprisingly, GATA-1 regulation of other vital constituents of the erythroid cell transcriptome. Bypassing ALAS-2 function in Alas2 cis element-mutant cells by providing its catalytic product 5-aminolevulinic acid rescues heme biosynthesis and the GATA-1-dependent genetic network. Heme amplifies GATA-1 function by downregulating the heme-sensing transcriptional repressor Bach1 and via a Bach1-insensitive mechanism. Through this dual mechanism, heme and a master regulator collaborate to orchestrate a cell type-specific transcriptional program that promotes cellular differentiation. © 2015 The Authors.

The relation between plasma concentrations of thyroxine (T4) and insulin-like growth factor-I (IGF-I) has been examined in young, growing pigs under controlled conditions of energy intake. Compared with euthyroid controls, plasma levels of IGF-I were significantly elevated (P less than 0.005) both in hypothyroid animals on the same food intake and in hyperthyroid animals on double the food intake. There was however no increase in IGF-I in a hyperthyroid group on the control level of intake. Contrary to previous reports in which energy intake was not controlled, it is concluded that there is no simple correlation between plasma concentrations of T4 and IGF-I.

Full Text Available Brain-derived neurotrophic factor (BDNF has been shown to have protective effects against cardiovascular diseases and death through neural and non-neural pathways via tropomyosin-related kinase B signaling. However, it is not known whether plasma BDNF concentration is a predictor of chronic kidney disease (CKD.This study was conducted as a prospective cohort study as part of the Hyogo Sleep Cardio-Autonomic Atherosclerosis.We measured plasma BDNF concentration in 324 patients without CKD, defined as an estimated glomerular filtration rate (eGFR less than 60 ml/min/1.73m2, and with cardiovascular risk factors. As potential confounders, sleep condition, nocturnal hypertension, and autonomic function were quantitatively examined. The patients were followed for a median 37 months (range 2-59 months and occurrence of CKD was noted.Plasma BDNF concentration was significantly and independently associated with CKD development, which occurred in 38 patients (11.7%. Kaplan-Meier analysis revealed that patients with reduced plasma BDNF concentration exhibited a significantly (p = 0.029 greater number of CKD events as compared to those with a higher concentration. Moreover, comparisons of key subgroups showed that the risk of CKD in association with low plasma BDNF concentration was more prominent in patients with a greater reduction of nocturnal systolic blood pressure, better movement index, higher standard deviations of the NN(RR interval or average NN(RR interval for each 5-minute period, and without past cardiovascular disease events, smoking habit, or albuminuria.Plasma BDNF concentration is an independent predictor for development of CKD in patients with cardiovascular risk factors.

Full Text Available This paper attempts to empirically investigate the determinants of choices of corporate governance practices by corporations in a transition market. The study offers firm-level evidence benefiting from unique financial and governance data on Ukraine. In particular, we analyze the factors that affect overall level as well as individual elements of corporate governance. We consider such governance elements as shareholder rights, transparency, board independence, chairman independence and ownership. Overall we found that regulatory, industry and firm level factors are important, which is consistent with previous literature for other countries. Combining our results with the results of Zheka (20063 we conclude that it is possible for the government to implement and enforce better corporate governance practices in the economy that would make Ukrainian enterprises more attractive for foreign investment.

Placental growth factor (PlGF) has been suggested as a possible biomarker for major placenta-related disorders such as preeclampsia and intrauterine growth restriction. However, experimental findings suggest that PlGF concentrations may be influenced by other factors besides the placenta. In the present study, we examined how acute fetal injury affects PlGF concentrations in maternal circulation. We therefore monitored PlGF concentrations in maternal circulation before and after feticide. A prospective comparative study was performed. Blood samples were drawn prospectively between January and July 2012, before and after feticide at predetermined time points in relation to the procedure (0, 30, 60, and 120 min). The levels of lactate dehydrogenase (LDH) in the maternal circulation were measured to detect acute tissue damage. PlGF concentrations were measured by standard human ELISA. Following feticide (60 and 120 min), PlGF concentrations decreased significantly compared to the concentrations before feticide. LDH concentrations did not change before and after feticide. Our finding, along with the detailed review of the literature described in our work, supports a new concept in which primary fetal distress can affect PlGF concentration in maternal circulation. A large-scale study is required to strengthen our finding.

From twenty-third meeting of the International Commission for Scientific Exploitation of the Mediterranean Sea; Athens, Greece 13 Nov 1972). Mussels, collected at various times during the year, were placed in aquariums operating in closed circuit in a room kept at 14 to 16 deg C. Solutions of /sup 60/Co in HCl were added to the aquariums and the mussels were introduced in the contaminated medium when the radioactivity of the water was stabilized. Under the experimental conditions used the radiocobalt introduced in the cation form evolved toward the anion form. The radioactivity of the flesh and the shells of the mussels was measured separately with the aid of a multichannel analyzer. The results were expressed in concentration factor with respect to the water. An increase of the concentration factor of the meat was noted when the concentration level of the water passed from 1 to 7 mu Ci/l. A lower content was found for the shell than for the meat. (JSR)

The current international energy trade governance system is fragmented and multi-layered. Streamlining it for greater legal cohesiveness and international political and economic cooperation would promote global energy security. The current article explores three levels of energy trade governance: multilateral, regional and bilateral. Most energy-rich countries are part of the multilateral trading system, which is institutionalized by the World Trade Organization (WTO). The article analyzes the multilateral energy trade governance system by focusing on the WTO and energy transportation issues. Regionally, the article focuses on five major regional agreements and their energy-related aspects and examines the various causes that explain the proliferation of regional trade agreements, their compatibility with WTO law, and then provides several examples of regional energy trade governance throughout the world. When it comes to bilateral energy trade governance, this article only addresses the European Union’s (EU) bilateral energy trade relations. The article explores ways in which gaps could be filled and overlaps eliminated whilst remaining true to the high-level normative framework, concentrating on those measures that would enhance EU energy security.

The Governing Board held its 120th and 121st meetings on 4 November and 2 December 2003 respectively. At the first of these two meetings, the Board first continued its examination of ESO's requests. In connection to this, the Board heard a presentation of the requests by M. Bloch, ESO's Head of Personnel, including a proposal that ESO's contributions and benefits to its beneficiaries be paid in euros. This option had previously been examined by the Working Group on ESO's Requests which had submitted a negative opinion to the Governing Board. Mr Bloch informed the Board that ESO was suspending that request and therefore invited the Governing Board to concentrate on the other options. After some discussion, the Governing Board decided that the euro-based request should be deemed withdrawn and that the Working Group would resume its examination of the other options put forward by ESO at the beginning of the year. At the same meeting, J.-P. Matheys reported on the recent meeting of the Working Group on Actuarial...

2004-06-01

Full Text Available Abstract Background Chronic lung disease (CLD in the preterm newborn is associated with inflammation and fibrosis. Platelet-derived growth factor-BB (PDGF-BB, a potent chemotactic growth factor, may mediate the fibrotic component of CLD. The objectives of this study were to determine if tracheal aspirate (TA concentrations of PDGF-BB increase the first 2 weeks of life in premature neonates undergoing mechanical ventilation for respiratory distress syndrome (RDS, its relationship to the development of CLD, pulmonary hemorrhage (PH and its relationship to airway colonization with Ureaplasma urealyticum (Uu. Methods Infants with a birth weight less than 1500 grams who required mechanical ventilation for RDS were enrolled into this study with parental consent. Tracheal aspirates were collected daily during clinically indicated suctioning. Uu cultures were performed on TA collected in the first week of life. TA supernatants were assayed for PDGF-BB and secretory component of IgA concentrations using ELISA techniques. Results Fifty premature neonates were enrolled into the study. Twenty-eight infants were oxygen dependent at 28 days of life and 16 infants were oxygen dependent at 36 weeks postconceptual age. PDGF-BB concentrations peaked between 4 and 6 days of life. Maximum PDGF-BB concentrations were significantly higher in infants who developed CLD or died from respiratory failure. PH was associated with increased risk of CLD and was associated with higher PDGF-BB concentrations. There was no correlation between maximum PDGF-BB concentrations and Uu isolation from the airway. Conclusions PDGF-BB concentrations increase in TAs of infants who undergo mechanical ventilation for RDS during the first 2 weeks of life and maximal concentrations are greater in those infants who subsequently develop CLD. Elevation in lung PDGF-BB may play a role in the development of CLD.

Corporate governance and corporate social responsibility: A typology of OECD countries

Directory of Open Access Journals (Sweden)

Patricia Crifo

2016-06-01

Full Text Available This article investigates the relationships between corporate governance and Corporate Social Responsibility (CSR. The underlying intuition is that governance factors are major determinants of CSR policies and extra-financial performance. More precisely, we identify three main factors that determine the strength of CSR engagement at the firm level: the structure of equity ownership (identity of shareholders, the composition and structure of board of directors, and the regulatory framework on corporate governance and CSR. We show how evolutions regarding corporate governance over the three previous decades have paved the way and shaped the rise of CSR. In addition, we elaborate a typology of CSR and governance structures that characterize OECD countries depending on whether the CSR reporting regime is stringent versus non-stringent, and on whether the corporate governance model is based on the shareholder, stakeholder or hybrid regime.

Clinical evidence supports the efficacy of bimonthly aflibercept injection for age-related macular degeneration. The study aimed to evaluate aqueous vascular endothelial growth factor and aflibercept concentrations and the efficacy of bimonthly aflibercept in patients with age-related macular degeneration. This study is a prospective, interventional case series. Enrolled were 35 eyes with exudative age-related macular degeneration from 35 patients. Patients received three bimonthly intravitreal aflibercept without loading doses. We collected the aqueous humor just before each injection, measured vascular endothelial growth factor and aflibercept concentrations by enzyme-linked immunosorbent assay and measured best-corrected visual acuity and central retinal subfield thickness before and after the injections. Aqueous vascular endothelial growth factor and aflibercept concentrations were measured. The vascular endothelial growth factor concentration was 135.4 ± 60.5 pg/mL (mean ± standard deviation, range 60.6-323.4) at baseline and below the lowest detectable limit in all eyes at month 2 and in 32 eyes at month 4 (P age-related macular degeneration. © 2017 Royal Australian and New Zealand College of Ophthalmologists.

Government regulation as an impetus for innovation: Evidence from energy performance regulation in the Dutch residential building sector

International Nuclear Information System (INIS)

Beerepoot, Milou; Beerepoot, Niels

2007-01-01

The recent implementation of energy performance policy as a way to tackle energy consumption in the building sector in Europe draws attention to the effect it has on the development and diffusion of energy-saving innovations. According to innovation system literature, government regulation through norms and standards is one of the factors stimulating innovation. This paper concentrates on the role of stricter government regulation as an incentive to innovation in the Dutch residential building sector. Innovation in this sector is predominantly a process of applying incremental modifications to comply with new and stricter government regulations and standards. Energy performance policy in its current shape will therefore not contribute to the diffusion of really new innovation in energy techniques for residential buildings in the Netherlands. If diffusion of really new innovation is an explicit aim of energy performance policy then the European wide introduction of this scheme needs reconsideration

2013-12-01

Full Text Available To complement this Special Feature on global water governance, we focused on a generic challenge at the global level, namely, the degree to which water issues need to be dealt with in a centralized, concentrated, and hierarchical manner. We examined water ecosystem services and their impact on human well-being, the role of policies, indirect and direct drivers in influencing these services, and the administrative level(s at which the provision of services and potential trade-offs can be dealt with. We applied a politics of scale perspective to understand motivations for defining a problem at the global or local level and show that the multilevel approach to water governance is evolving and inevitable. We argue that a centralized overarching governance system for water is unlikely and possibly undesirable; however, there is a need for a high-level think tank and leadership to develop a cosmopolitan perspective to promote sustainable water development.

Science.gov (United States)

Gross, Eliza L.; Low, Dennis J.

2013-01-01

Analytical results for arsenic in water samples from 5,023 wells obtained during 1969–2007 across Pennsylvania were compiled and related to other associated groundwater-quality and environmental factors and used to predict the probability of elevated arsenic concentrations, defined as greater than or equal to 4.0 micrograms per liter (µg/L), in groundwater. Arsenic concentrations of 4.0 µg/L or greater (elevated concentrations) were detected in 18 percent of samples across Pennsylvania; 8 percent of samples had concentrations that equaled or exceeded the U.S. Environmental Protection Agency’s drinking-water maximum contaminant level of 10.0 µg/L. The highest arsenic concentration was 490.0 µg/L.

of regulatory measures and options). We present ethical and legal analyses of the current stalemate on bioenergy governance in the EU using two illustrative cases: liquid biofuels for transport and solid biomass-based bioenergy. The two cases disclose some similarities between these two factors......, but the remaining differences may partly explain, or justify, contrasting forms of governance. While there seems to be no easy way in which the EU and national governments can deal with the multiple sustainability issues raised by bioenergy, it is argued that failure to deal explicitly with the underlying value...... disagreements, or to make apparent the regulatory complexity, clouds the issue of how to move forward with governance of bioenergy. We suggest that governance should be shaped with greater focus on the role of value disagreements and regulatory complexity. There is a need for more openness and transparency...

Full Text Available Technological developments and governments’ understanding of what citizens need usually determine the design of public online services. For successful implementation of e-Government services, governments have to place the user in the center of future developments, understand what citizens need and measure what increases citizens’ willingness to adopt e-government services. The paper uses the Technology Acceptance Model (TAM, the extended TAM, the Diffusion of Innovations (DOI theory and the important determinants of user acceptance perceived risk and trust, in order to describe teachers’ behavioral intensions to adopt e-Government services. A model containing trust and risk, along with cognitive, social and intrinsic factors is used to study the intentions of e-Government use by Greek primary and secondary education teachers. Two hundred and thirty teachers responded to an online survey. Findings reveal that cognitive and intrinsic factors have significant effects on intentions to use e-Government websites.

Full Text Available Private actors in the information technology sector are currently playing an increasingly important role in content mediation, as well as in regulation of online forms of expression, with implications for both internet rights and economic freedom. The “privatisation of internet governance” (DeNardis, 2010, is not a new dynamic; however, in a scenario in which users are taking advantage of increasingly sophisticated technology, the centralisation and concentration characterising today’s most widespread internet services are contributing to the accentuation of this tendency. The 'inherently political' qualities of search engine algorithm development, video content removals, blocking of domain names – actions that originate and rest with the private sector’s handling of the internet’s infrastructure – should not be neglected in our assessment of the field of internet governance today.

Chlorogenic acid (CA) has been reported to inhibit several pathogens, but the influence of subinhibitory concentrations of CA on virulence expression of pathogens has not been fully elucidated. The aim of this study was to explore the effect of CA on the virulence factor production of Staphylococcus aureus. The minimum inhibitory concentration (MIC) of CA against S. aureus was determined using a broth microdilution method. Hemolysin assays, coagulase titer assays, adherence to solid-phase fibrinogen assays, Western blot, and real-time reverse transcriptase-polymerase chain reaction were performed to evaluate the effect of subinhibitory concentrations of CA on the virulence factors of S. aureus. MIC of CA against S. aureus ATCC29213 was found to be 2.56 mg/mL. At subinhibitory concentrations, CA significantly inhibited the hemolysis and dose-dependently decreased coagulase titer. Reduced binding to fibrinogen and decreased production of SEA were observed with treatment of CA at concentrations ranging from 1/16MIC to 1/2MIC. CA markedly inhibited the expression of hla, sea, and agr genes in S. aureus. These data demonstrate that the virulence expression of S. aureus could be reduced by CA and suggest that CA could be potentially developed as a supplemental strategy to control S. aureus infection and to prevent staphylococcal food poisoning.

Highlights: • Experimental characterization of a concentrating photovoltaic system. • Analysis of the point-focus concentrating system performances. • Photovoltaic system parameters as function of the concentration factor. - Abstract: The concentrating photovoltaic system represents one of the most promising solar technologies because it allows a more efficient energy conversion. When a CPV system is designed, the main parameter which has to be considered is the concentration factor that affects both the system energy performances and its configuration. An experimental characterization of a CPV system previously realized at the University of Salerno, is presented in this paper considering several aspects related to the optical configuration, the concentration factor and the solar cell used. In particular, the parameters of an Indium Gallium Phosphide/Gallium Arsenide/Germanium triple-junction solar cell are investigated as function of the concentration factor determined by means of an experimental procedure that uses different optical configurations. The maximum concentration factor reached by the CPV system is 310 suns. The cell parameters dependence on the concentration is reported together with an electroluminescence analysis of the Indium Gallium Phosphide/Gallium Arsenide/Germanium cell. A monitoring of the electrical power provided by the system during its working is also presented corresponding to different direct irradiance values. A mean power of 2.95 W with an average efficiency of 32.8% is obtained referring to a mean irradiance of 930 W/m"2; lower values are obtained when the irradiance is highly fluctuating. The concentrating photovoltaic system electric energy output is estimated considering different concentration levels; the maximal obtained value is 23.5 W h on a sunny day at 310×. Finally, the temperature of the triple-junction solar cell is evaluated for different months in order to evaluate the potential annual thermal energy production

In traditional houses in rural areas of Northern China, most traditional heating systems, heated by mini-stove in the kitchen, usually take agricultural residues as fuels resources. Besides, burning cave under the ground-floor of a rural house is also widely used. The higher PM2.5 concentration is crisis for human health. In this study, PM2.5 concentration, temperature, relative humidity inside and outside the houses have been measured, moreover the factors impact on I/O rate coefficient has been discussed. The results show that the I/O rate coefficient in the evening is 2.5 times greater than the I/O rate coefficient in the daytime. I/O rate coefficient of PM2.5 concentration is positive related to air temperature difference between indoor and outdoor. In addition, the impact of outdoor wind speed and predominant wind direction on the PM2.5 emission has been studied.

The hydrology of wetland ecosystems is a key driver of both mercury (Hg) methylation and waterbird foraging ecology, and hence may play a fundamental role in waterbird exposure and risk to Hg contamination. However, few studies have investigated hydrological factors that influence waterbird Hg exposure. We examined how several landscape-level hydrological variables influenced Hg concentrations in great egret and white ibis adults and chicks in the Florida Everglades. The great egret is a visual "exploiter" species that tolerates lower prey densities and is less sensitive to hydrological conditions than is the white ibis, which is a tactile "searcher" species that pursues higher prey densities in shallow water. Mercury concentrations in adult great egrets were most influenced by the spatial region that they occupied in the Everglades (higher in the southern region); whereas the number of days a site was dry during the previous dry season was the most important factor influencing Hg concentrations in adult ibis (Hg concentrations increased with the number of days dry). In contrast, Hg concentrations in egret chicks were most influenced by calendar date (increasing with date), whereas Hg concentrations in ibis chicks were most influenced by chick age, region, and water recession rate (Hg concentrations decreased with age, were higher in the southern regions, and increased with positive water recession rates). Our results indicate that both recent (preceding two weeks) hydrological conditions, and those of the prior year, influence Hg concentrations in wading birds. Further, these results suggest that Hg exposure in wading birds is driven by complex relationships between wading bird behavior and life stage, landscape hydrologic patterns, and biogeochemical processes.

Shuang Xue

2016-03-01

Full Text Available Cost and expense stickiness is an important issue in accounting and economics research, and the literature has shown that cost stickiness cannot be separated from managers’ motivations. In this paper, we examine the effects that earnings management has on expense stickiness. Defining small positive profits or small earnings increases as earnings management, we observe significant expense stickiness in the non-earnings-management sub-sample, compared with the earnings-management sub-sample. When we divide expenses into R&D, advertising and other general expenses, we find that managers control expenses mainly by decreasing general expenses. We further examine corporate governance’s effect on expense stickiness. Using factor analysis, we extract eight main factors and find that good corporate governance reduces expense stickiness. Finally, we investigate the interaction effects of earnings management and corporate governance on expense stickiness. The empirical results show that good corporate governance can further reduce cost stickiness, although its effect is not as strong as that of earnings management.

Identifying Motivation of the Local Governments to Improve the Sustainability Transparency

Full Text Available This paper examines the sustainability tran-sparency of governments, i.e., the disclosure of information on the sustainability of their ac-tions. To do so, we identify contributory factors to the online disclosure of environmental, social, economic and general information by local gov-ernments in Nordic countries. Linear regression analysis was used to identify factors inf uencing the online dissemination of government infor-mation on sustainability; a factor analysis, as a precursor to linear regression, led us to reduce 14 explanatory variables to four factors: f nancial risk, demography, professional qualif cations and local government resources. The results obtained show that local f -nancial priorities have a greater impact on the sustainability-related content of governmental websites than does concern for the needs of the population. Furthermore, an organization’s dis-closure of its f nancial risks, together with greater awareness of stakeholders’ demands, could pro-mote transparency in the f eld of environmental, social and economic sustainability, while local demographic characteristics could foster the publication of information on environmental sus-tainability.

Highlights: •Estradiol (E2) at low dose induced cell proliferation in breast cancer cells. •E2 at high concentration induced cell stress in breast cancer cells. •Estrogen receptor physically interacts only with a few transcription factors. •Differential expression of genes with Oct-1 binding sites increased under stress. •Transcription factor binding sites showed distinct spatial distribution on genes. -- Abstract: Background: Breast cancer cells respond to estrogen in a concentration dependent fashion, resulting in proliferation or apoptosis. The mechanism of this concentration dependent differential outcome is not well understood yet. Methodology: Meta-analysis of the expression data of MCF7 cells treated with low (1 nM) or high (100 nM) dose of estradiol (E2) was performed. We identified genes differentially expressed at the low or the high dose, and examined the nature of regulatory elements in the vicinity of these genes. Specifically, we looked for the difference in the presence, abundance and spatial distribution of binding sites for estrogen receptor (ER) and selected transcription factors (TFs) in the genomic region up to 25 kb upstream and downstream from the transcription start site (TSS) of these genes. Results: It was observed that at high dose E2 induced the expression of stress responsive genes, while at low dose, genes involved in cell cycle were induced. We found that the occurrence of transcription factor binding regions (TFBRs) for certain factors such as Sp1 and SREBP1 were higher on regulatory regions of genes expressed at low dose. At high concentration of E2, genes with a higher frequency of Oct-1 binding regions were predominantly involved. In addition, there were differences in the spatial distribution pattern of the TFBRs in the genomic regions among the two sets of genes. Discussion: E2 induced predominantly proliferative/metabolic response at low concentrations; but at high concentration, stress–rescue responses were induced

In Jehovah's Witness patients, the use of red blood cells, platelets, and fresh frozen plasma is not optional. Various blood conservation techniques are available, but complex cardiac surgery remains a major challenge. The feasibility of fractions of "primary components" has not been fully considered in published case reports. For Jehovah's Witness patients who preoperatively give consent, factor IX concentrates may be acceptable for hemostatic therapy. We hereby describe a combination of "secondary components" to prevent excessive bleeding in a Jehovah's Witness patient undergoing complex replacement of the aortic arch.

What governs governance, and how does it evolve? The sociology of governance-in-action.

Fox, Nick J; Ward, Katie J

2008-09-01

Governance addresses a wide range of issues including social, economic and political continuity, security and integrity, individual and collective safety and the liberty and rights to self-actualization of citizens. Questions to be answered include how governance can be achieved and sustained within a social context imbued with cultural values and in which power is distributed unevenly and dynamically, and how governance impacts on individuals and institutions. Drawing on Gramscian notions of hegemony and consent, and recent political science literatures on regulation and meta-regulation, this paper develops a sociological model of governance that emphasizes a dynamic and responsive governance in action. Empirical data from a study of pharmaceutical governance is used to show how multiple institutions and actors are involved in sustaining effective governance. The model addresses issues of how governance is sustained in the face of change, why governance of practices varies from setting to setting, and how governance is achieved without legislation.

Stress concentration factors for an internally pressurized circular vessel containing a radial U-notch

International Nuclear Information System (INIS)

Carvalho, E.A. de

2005-01-01

This paper evaluates the stress concentration factors for an internally pressurized cylinder containing a radial U-notch along its length. This work studies the cases where the external to internal radius ratio (Ψ) is equal to 1.26, 1.52, 2.00, and 3.00 and the notch radius to internal radius ratio (Φ) is fixed and equal to 0.026. The U-notch depth varies from 0.1 to 0.6 of the wall thickness. Results are also presented for a fixed size semi-circular notch. Hoop stresses at the external wall are presented, showing regions where the stress matches the nominal one and the favourable places to install strain sensors. The finite element method is used to determine the stress concentration factors (K t ) for the above described situations and for a special case where a varying semi-circular notch is present with Ψ=3.00. This notch depth varies from 0.013 to 0.3 of the wall thickness. It is pointed out that even relatively small notches introduce large stress concentrations and disrupt the hoop stress distribution all over the cross section. Results are also compared to an example found in the literature for semi-circular notches and K t curves for both cases present the same shape

Citizen Perceptions of E-Government in the Kurdistan Region of Iraq

Khosro Mohammad Ahmed

2015-11-01

Full Text Available Despite increasing investment by governments globally, citizens in some countries are less willing to engage with e-government innovations. While previous studies have examined what might encourage citizens to adopt e-government services more broadly, further research is required to understand those factors that impede or enable e government adoption in countries that have, or are in the process of, transitioning to democratic self-rule. This study is the first to investigate citizen attitudes to e-government adoption in the Kurdistan Region of Iraq and thus provides insight into the factors affecting the adoption of e-government within an emerging democratic state. This study also distinguishes between two types of e-government services; informational and transactional. Thus a research model with two elements is developed and tested; one for intention to use informational e government and one for intention to use transactional e-government. Data were collected through a survey administered to university students and non-academic employees in Arbil the capital city of Kurdistan, and analysed using structural equation modelling. Perceived usefulness, social influence, trust in government and perceived risk were found to be significantly and directly associated with the intention to use both kinds of e-government services. However perceptions of ease of use, information quality and trust in the Internet were not significant.

Environmental factors and the risk of urinary schistosomiasis in Ile Oluji/Oke Igbo local government area of Ondo State

Full Text Available Geographic information systems are being increasingly used to show the distributions of disease where data for specific environmental risk factors are available. For successful transmission of schistosomiasis, suitable climatic conditions and biological events must coincide; hence its distribution and prevalence are greatly influenced by environmental factors affecting the population of snail intermediate hosts and human hosts. Prevalence and demographic data was obtained by parasitological examination of urine samples and questionnaire administration. The mean values of environmental factors corresponding to the local government area were obtained from remotely sensed images and data from climate research unit. The effects of the environmental factors were determined by using regression analysis to analyse the correlation of environmental factors to prevalence of schistosomiasis. There was a negative correlation between infection and elevation. There was a positive correlation between vegetation, rainfall, slope, temperature and prevalence of infection. There was also a weak negative correlation between proximity to water body and prevalence. The result shows the study area to be at low to high risk of infection.

Imaging shear stress distribution and evaluating the stress concentration factor of the human eye

Joseph Antony, S.

2015-03-01

Healthy eyes are vital for a better quality of human life. Historically, for man-made materials, scientists and engineers use stress concentration factors to characterise the effects of structural non-homogeneities on their mechanical strength. However, such information is scarce for the human eye. Here we present the shear stress distribution profiles of a healthy human cornea surface in vivo using photo-stress analysis tomography, which is a non-intrusive and non-X-ray based method. The corneal birefringent retardation measured here is comparable to that of previous studies. Using this, we derive eye stress concentration factors and the directional alignment of major principal stress on the surface of the cornea. Similar to thermometers being used for monitoring the general health in humans, this report provides a foundation to characterise the shear stress carrying capacity of the cornea, and a potential bench mark for validating theoretical modelling of stresses in the human eye in future.

Reconstituting factor concentrates: Defining Evidence of Coaching Non-Experts (DEVICE) in haemophilia--a prospective randomized feasibility study.

Bidlingmaier, C; Kurnik, K; Hölscher, G; Kappler, M

2007-09-01

The introduction of new needleless devices as demanded by the US Department of Labor Occupational Safety and Health Administration (OSHA) has caused problems with the reconstitution of antihaemophilic factor in emergency situations. Our aim therefore was to evaluate the feasibility of a needleless device for reconstitution of antihaemophilic factor for non-haemophilia experts and to define evidence of the need for coaching these physicians via providing two additional photographs illustrating the two key points of the factor reconstitution process. Twenty-eight physicians of a tertiary care university children's hospital were randomized into two groups, either with no further explanation of the reconstitution device or with two additional photographs, showing the two key steps of the procedure. Reconstitution of dummy-factor concentrate was video-taped and evaluated by a blinded helper. Main outcome measure was the successful reconstitution of dummy-factor concentrate and procedure failure respectively. Of the group without explanation of the reconstitution device, only two of 14 physicians were able to reconstitute the dummy-factor concentrate. Of the group receiving two photographs, nine of 14 completed the task successfully (P = 0.0068). The needleless device is not self explaining to non-haemophilia physicians involved in emergency services. Coaching via short to the point instructions as provided by simple visual educational material therefore is crucial to enable these physicians to resolve the expensive emergency drug quickly and correctly. Companies concerned with the production of any devices to dissolve drugs, especially for treatment of rare diseases as haemophilia, therefore should take measures to simplify therapy.

A review of environmental governance and its effects on concentrate discharge from desalination plants in the Kingdom of Saudi Arabia

KAUST Repository

Van Der Merwe, Riaan

2013-01-01

The most likely environmental impact of concentrate discharges (in most instances twice the concentration of the ambient environment) leaking from desalination plants on local marine ecosystems has been controversially discussed for many years. Increasing water demand and lack of renewable natural water resources in Saudi Arabia also result in greater dependence on desalination and consequently amplify the impact on marine environment and multifactorial ecosystems in near-field areas of desalination discharges. Accurate scientific baseline data should furnish information on various factors such as intake- and outfall locality, brine (concentrate) discharge and chemical characteristics (i.e. effluent concentration, mass flow rates (flux)), local effects, and even cumulative effects of desalination activities, at least on a regional and even on a national scale. Even if such data were available, in many cases they are non-transparent and are not even accessible, or tend to be overlooked as a result of ambiguous desalination-related policies. This paper focuses on national environmental regulations in the Kingdom of Saudi Arabia (KSA) and how such regulations help control the flow of concentrate discharge into the receiving waters. © 2013 Desalination Publications.

The pattern of secretion of many hormones, including prolactin, is dependent on the circadian rhythm. Night shift work involves exposure to artificial light at night and sleep deficiency, which in turn can affect prolactin synthesis. The aim of this study was to evaluate a possible association between night shift work characteristics, sleep quality, lifestyle factors and prolactin concentration, using data from a cross-sectional study of nurses and midwives. A cross-sectional study was conducted among 327 nurses and midwives currently working on rotating night shifts, and 330 nurses and midwives working during the day (aged 40-60 years) (388 premenopausal and 269 postmenopausal). Information about night shift work characteristics, lifestyle, reproductive factors, sleep pattern and other covariates was collected through a face-to-face interview, and from a one-week work and sleep diary completed by the subjects. Weight and height were measured. Prolactin concentration was measured in the morning blood sample using the electrochemiluminesence immunoassay method. Associations were analyzed using linear regression models adjusted for important confounders. Analyses were carried out separately in pre- and postmenopausal women. None of the night shift work or sleep characteristics was significantly associated with prolactin concentration. Prolactin concentration was significantly (p night shift work is not associated with prolactin concentration. Smoking, parity, time of blood collection and age among postmenopausal women were significant determinants of prolactin.

2018-03-01

We present field measurement data and modeling of multiple traffic-related air pollutants during two seasons at a site adjoining Interstate 40, near Durham, North Carolina. We analyze spatial-temporal and seasonal trends and fleet-average pollutant emission factors and use our data to evaluate a line source dispersion model. Month-long measurement campaigns were performed in summer 2015 and winter 2016. Data were collected at a fixed near-road site located within 10 m from the highway edge, an upwind background site and, under favorable meteorological conditions, along downwind perpendicular transects. Measurements included the size distribution, chemical composition, and volatility of submicron particles, black carbon (BC), nitrogen oxides (NOx), meteorological conditions and traffic activity data. Results show strong seasonal and diurnal differences in spatial distribution of traffic sourced pollutants. A strong signature of vehicle emissions was observed within 100-150 m from the highway edge with significantly higher concentrations during morning. Substantially higher concentrations and less-sharp near-road gradients were observed in winter for many species. Season-specific fleet-average fuel-based emission factors for NO, NOx, BC, and particle number (PN) were derived based on up- and down-wind roadside measurements. The campaign-average NOx and PN emission factors were 20% and 300% higher in winter than summer, respectively. These results suggest that the combined effect of higher emissions and their slower downwind dispersion in winter dictate the observed higher downwind concentrations and wider highway influence zone in winter for several species. Finally, measurements of traffic data, emission factors, and pollutant concentrations were integrated to evaluate a line source dispersion model (R-LINE). The dispersion model captured the general trends in the spatial and temporal patterns in near-road concentrations. However, there was a tendency for the model

Serum cystatin C concentrations are reported to increase in the hyperthyroid state. Serum concentrations of cystatin C and transforming growth factor-β1 (TGF-β1) were measured in patients with thyroid dysfunction, and the effects of 3,5,3'-tri-iodothyronine (T(3)) and TGF-β1 on cystatin C production in human hepatoblastoma (Hep G2) cells were studied. Serum concentrations of cystatin C and TGF-β1 were significantly higher in patients with Graves' disease compared with control subjects. Significantly positive correlations were observed between thyroid hormones and cystatin C, thyroid hormones and TGF-β1, and TGF-β1 and cystatin C in patients with thyroid dysfunction. Serum concentrations of cystatin C and TGF-β1 decreased after treatment for hyperthyroidism. Cystatin C mRNA levels and cystatin C secretion were increased by T(3) and TGF-β1 in cultured Hep G2 cells. These results suggest that serum cystatin C concentrations increase in patients with hyperthyroidism. The mechanisms for this may involve elevation of serum TGF-β1 levels and the stimulatory effects of T(3) and TGF-β1 on cystatin C production.

Full Text Available The aim of this study was to evaluate PM10 concentration in three different laying hens houses (traditional battery cages with aerated open manure storage, aviary system and vertical tiered cages with manure belts with forced air drying and to evaluate particulate matter emission into atmosphere during one year of observation. Internal and external temperature and relative humidity, ventilation rate, PM10 concentration have been continuously monitored in order to evaluate particulate matter concentration changes during the day and the season and to define PM10 emission factors. PM10 concentration was corrected by gravimetric technique to lower measurements error. In the aviary system house, TSP and fine particulate matter (particles smaller than 2.5 micron concentration was measured. Average yearly PM10 concentration was remarkably higher in the aviary system house with 0.215 mg m-3 vs 108 mg m-3 for the ventilated belt house and vs 0.094 mg m-3 for the traditional battery cages house. In the Aviary system housing, TSP concentration was 0.444 mg m-3 and PM2.5 was 0.032 mg m-3, highlighting the existence of a severe working environment for men and animals. Recorded values for PM10 emission were 0.433 mg h-1 hen-1 for battery cages housing type, 0.081 mg h-1 hen-1 for ventilated belt cages house, values lower than those available in literature, while the aviary system housing type showed the highest PM10 emission (1.230 mg h-1 hen-1 with appreciable peaks during the morning, together with the increased animal activity and daily farmer operations, as feed administration, cleaning and droppings removal.

The construction of sluices creates a strong disturbance in water environmental factors within a river. The change in water pollutant concentrations of sluice-controlled river reaches (SCRRs) is more complex than that of natural river segments. To determine the key factors affecting water pollutant concentration changes in SCRRs, river reaches near the Huaidian Sluice in the Shaying River of China were selected as a case study, and water quality monitoring experiments based on different regulating modes were implemented in 2009 and 2010. To identify the key factors affecting the change rates for the chemical oxygen demand of permanganate (CODMn) and ammonia nitrogen (NH3-N) concentrations in the SCRRs of the Huaidian Sluice, partial correlation analysis, principal component analysis and principal factor analysis were used. The results indicate four factors, i.e., the inflow quantity from upper reaches, opening size of sluice gates, water pollutant concentration from upper reaches, and turbidity before the sluice, which are the common key factors for the CODMn and NH3-N concentration change rates. Moreover, the dissolved oxygen before a sluice is a key factor for the permanganate concentration from CODMn change rate, and the water depth before a sluice is a key factor for the NH3-N concentration change rate. Multiple linear regressions between the water pollutant concentration change rate and key factors were established via multiple linear regression analyses, and the quantitative relationship between the CODMn and NH3-N concentration change rates and key affecting factors was analyzed. Finally, the mechanism of action for the key factors affecting the water pollutant concentration changes was analyzed. The results reveal that the inflow quantity from upper reaches, opening size of sluice gates, permanganate concentration from CODMn from upper reaches and dissolved oxygen before the sluice have a negative influence and the turbidity before the sluice has a positive

Atmospheric particulate matter (PM) is made up of a mixture of solid and aqueous species which enter the atmosphere by anthropogenic and natural pathways. The levels and composition of ambient air PM depend on the climatology and on the geography (topography, soil cover, proximity to arid zones or to the coast) of a given region. Spain has particular difficulties in achieving compliance with the limit values established by the European Union (based on recommendations from the World Health Organization) for particulate matter on the order of 10 micrometers of diameter or less (PM10), but not only antropogenical emissions are responsible for this: some studies show that PM10 concentrations originating from these kinds of sources are similar to what is found in other European countries, while some of the geographical features of the Iberian Peninsula (such as African mineral dust intrusion, soil aridity or rainfall) are proven to be a factor for higher PM concentrations. This work aims to describe PM10 concentration levels in Cantabria (Northern Spain) and their relationship with the following meteorological variables: rainfall, solar radiation, temperature, barometric pressure and wind speed. Data consists of daily series obtained from hourly data records for the 2000-2010 period, of PM10 concentrations from 4 different urban-background stations, and daily series of the meteorological variables provided by Spanish National Meteorology Agency. The method used for establishing the relationships between these variables consists of several steps: i) fitting a non-stationary probability density function for each variable accounting for long-term trends, seasonality during the year and possible seasonality during the week to distinguish between work and weekend days, ii) using the marginal distribution function obtained, transform the time series of historical values of each variable into a normalized Gaussian time series. This step allows using consistently time series

Full Text Available Chinese responsibility for reducing Greenhouse Gas or carbon dioxide emission increases continuously. Chinese government suggested two targets; Alternative Fuel Vehicle output volume 500 thousand and AFV market share 5% by the end of 2011. However any of two targets did not come true. Therefore this study accessed the question, ‘why Chinese government initiative model for AFV promotion has been so poor?’ This study reviewed the transition process for AFV policies in China and made a structural analysis for three key policies since 2009. As a result the number of articles for related industries or factor endowments was relatively more than firm strategy or demand conditions. Also this study accessed the AFV strategy of Six SOEs from the perspective of social responsibility. Six SOEs have more concentrated on electric vehicle rather than hybrid vehicle with following the government leadership. However major EV or HEV models of them mostly were made by Joint Ventures being under control of foreign makers and the JVs have actually controlled over AFV business. So the limitation of Chinese government initiative model resulted from supplier-centric approach with targeting for public transportation and institution consumer, and it caused a failure to create the demand conditions of general customers.

Democracy, political participation and good governance in Nigeria

Directory of Open Access Journals (Sweden)

Dare E. Arowolo

2012-12-01

Full Text Available The practice of democracy in Nigeria over a decade ago has not yielded much needed good governance. This is because democracy is practiced in such a way that responsible and competent people are scared away. Scholars and keen observers have attempted at unraveling the factors militating against translating democracy into good governance. The paper revealed that democratisation in Nigeria is pervaded by electoral violence, manipulation of election results and political participation constraints. These identified challenges have made it impossible to attain consolidated democracy that can, in turn, facilitate good governance. Democracy is a catalyst for accountability, transparency and responsive government which brings about good governance. The paper insisted that governance collapse in Nigeria is reflexive of the perfunctory role of the political actors and it adopted elite theory to reinforce this argument. The paper adopted content analysis as a means of data gathering. It dwelt extensively on the synergy between democracy, political participation and good governance but queried the artificial gulf between them in Nigeria. It concluded by putting forth viable and pragmatic way forward.

Test results on 349 firm-years using OLS regression for each mechanism and 2SLS regression for simultaneous testing indicate the presence of interdependence between the mechanisms. both parsial and simultanously; managerial ownership and dividend policy does not significantly influence on the banking efficiency. Significant positive effect of the board size and institutional ownership when tested by OLS did not recur when tested simultaneously using 2SLS. Instead, the independent commissioner when tested by 2SLS have significant negative effect but using OLS no significant effect. There are three variables of corporate governance mechanisms have consistent effect on the banking efficiency; debt policy has significant negative effect, while the market concentration and market share have significant positive effect. Different results between the tests using OLS and 2SLS emphasize the interdependence of these mechanisms is also shown that application of the policy of corporate governance mechanisms should be done carefully so that the expected performance can be achieved.

Market failures and government policies in gas markets

International Nuclear Information System (INIS)

Mulder, M; Zwart, G.

2006-02-01

This memorandum analyses the fundamental characteristics of the natural gas market and its consequences for government policies. In the past, the European gas market was dominated by state-owned monopolists but since the start of the liberalisation, privatisation and re-regulation in the early 1990s, the market has fundamentally changed. Nevertheless, governments are still involved in the gas industry, not only in gas exporting countries such as Russia, but also in a country like the Netherlands where the government has imposed a cap on production from the main gas field (Groningen) as well as owns shares in the main wholesale trader (Gasunie Trade and Supply) which has the obligation to accept all gas offered by producers on the small fields. In the main report of this project we present a cost-benefit analysis of the Dutch gas-depletion policy. In this memorandum we explore the natural-gas market more broadly, looking for factors why government intervention may be needed using the welfare-economic approach according to which government intervention should be based on the presence of market failures. After a brief description of the main characteristics of the gas industry, we systematically analyse sources of market failures, such as geopolitical factors, economies of scale and externalities, and finally go into the question which policy options may be chosen to address those market failures

Prenatal exposure to perfluoroalkyl substances (PFAS) might affect child health; but maternal determinants of PFAS exposure are unclear. We evaluated the socio-demographic and dietary factors of prenatal PFAS concentrations in a Spanish birth cohort. We analyzed perfluorohexanesulfonic acid (PFHxS), perfluorooctanesulfonic acid (PFOS), perfluorooctanoic acid (PFOA), and perfluorononanoic acid (PFNA) in 1216 plasma samples collected during the 1(ST) trimester of pregnancy (2003-2008). We used multivariable linear regressions to assess the geometric mean (GM) ratios of PFAS concentrations by socio-demographic and dietary factors. We used analysis of variance (ANOVA) to assess the variability of PFAS concentrations by maternal factors. GM PFAS concentrations ranged from 0.55ng/mL for PFHxS to 5.77ng/mL for PFOS. Women born outside of Spain had lower PFAS concentrations (e.g. GM ratio for PFHxS 0.53[95%CI: 0.46, 0.60] than Spanish women. PFHxS and PFOA concentrations were higher in mothers from the regions of Sabadell (2.13[1.93, 2.35] and 1.73[1.60, 1.88], respectively) and Valencia (1.40[1.28, 1.54] and 1.42[1.31, 1.53], respectively) than Gipuzkoa. PFOA and PFNA concentrations decreased with parity (≥2 children: 0.79[0.67, 0.94] and 0.82[0.68, 0.99], respectively). Younger women (i.e. 6months compared to those who never breastfed (0.79[0.67, 0.94] and 0.82[0.71, 0.95], respectively). High intake of fish and shellfish during pregnancy (i.e. ≥5.6 servings/week) was associated with 11% (1.11[1.04, 1.18]) higher PFOS concentrations than the lowest intake group. Our ANOVA models explained 26% to 40% of PFAS concentrations variability. Prenatal PFAS concentrations were mainly determined by maternal country of birth, region of residence, previous breastfeeding and age. Fish and shellfish intake also contributed to PFOS and PFOA concentrations. Copyright © 2016 Elsevier Ltd. All rights reserved.

As a Local Government Agencies who perform public services, General Government Office already has utilized Reporting Information System of Local Government Implementation (E-LPPD). However, E-LPPD has upgrade limitation for the integration processes that cannot accommodate General Government Offices’ needs in order to achieve Good Government Governance (GGG), while success stories of the ultimate goal of e-government implementation requires good governance practices. Currently, citizen demand public services as private sector do, which needs service innovation by utilizing the legacy system as a service based e-government implementation, while Service Oriented Architecture (SOA) to redefine a business processes as a set of IT enabled services and Enterprise Architecture from the Open Group Architecture Framework (TOGAF) as a comprehensive approach in redefining business processes as service innovation towards GGG. This paper takes a case study on Performance Evaluation of Local Government Implementation (EKPPD) system on General Government Office. The results show that TOGAF will guide the development of integrated business processes of EKPPD system that fits good governance practices to attain GGG with SOA methodology as technical approach.

INFLUENCE OF HEXAVALENT CHROMIUM INITIAL CONCENTRATION ON RETARDATION FACTOR AND CONTAMINANT VELOCITY IN A SOIL MEDIA

Full Text Available Sources of soil and ground water contamination are many and include many folds of accidental spills and leaks of toxic and hazardous chemicals. Preparation of ground water contamination model needs good understanding of the behavior of contaminant transport through soil media for predicting the level of contamination of ground water in the near future at the intended site conditions. Sorption is a natural process; due to its presence, the contaminant can move slowly as compared to the ground water and hence the effects of sorption must be taken into consideration while predicting the travel time of the contaminant to reach the ground water sources. This paper discusses the results of column test studies carried out in the laboratory under controlled conditions about the spreading of contaminant (Hexavalent chromium, Cr (VI through the clay mixed red soil at two different initial concentrations (800 mg/L and 4200 mg/L. The variations of the contaminant flow velocity and retardation factor for two different initial concentrations of contaminant were brought out and discussed. The contaminant flow velocity drastically coming down for a relative concentration of 0 to 0.2 and beyond this range, the contaminant flow velocity value is decreasing in a slow rate for both the lower and higher initial contaminant concentrations tested. At the lower relative concentration, the higher retardation factor was observed and it may be due to slowly filling the available sorption sites in the soil column.

Rapid economic growth, industrialization, and urbanization in China have led to extremely severe air pollution that causes increasing negative effects on human health, visibility, and climate change. However, the influence mechanisms of these anthropogenic factors on fine particulate matter (PM 2.5 ) concentrations are poorly understood. In this study, we combined panel data and econometric methods to investigate the main anthropogenic factors that contribute to increasing PM 2.5 concentrations in China at the prefecture level from 1999 to 2011. The results showed that PM 2.5 concentrations and three anthropogenic factors were cointegrated. The panel Fully Modified Least Squares and panel Granger causality test results indicated that economic growth, industrialization, and urbanization increased PM 2.5 concentrations in the long run. The results implied that if China persists in its current development pattern, economic growth, industrialization and urbanization will inevitably lead to increased PM 2.5 emissions in the long term. Industrialization was the principal factor that affected PM 2.5 concentrations for the total panel, the industry-oriented panel and the service-oriented panel. PM 2.5 concentrations can be reduced at the cost of short-term economic growth and industrialization. However, reducing the urbanization level is not an efficient way to decrease PM 2.5 pollutions in the short term. The findings also suggest that a rapid reduction of PM 2.5 concentrations relying solely on adjusting these anthropogenic factors is difficult in a short-term for the heavily PM 2.5 -polluted panel. Moreover, the Chinese government will have to seek much broader policies that favor a decoupling of these coupling relationships.

Full Text Available This study examines the impacts of ESG on the corporate performance government-linked companies (GLCs in Malaysia. For the period 2006-2012, ESG disclosure data were extracted from the Sustainalytics ESG performance reports, while financial data were obtained from the Bloomberg database. Data development analysis (DEA was used to estimate efficiency in the first stage; a regression analysis was performed to test the relationship between ESG and efficiency in the second stage. The empirical results of this study show that GLCs focused more on governance disclosures, followed by social and environmental aspects. Moreover, governance will improve firm efficiency, but social and environmental factors have no similar effect. In conclusion, this study provides insight on the limited literature on ESG and informs the relevant stakeholders on the important ESG components for financial and investment decisions.

To identify factors associated with blood concentrations of hydroxychloroquine (HCQ) and its major metabolite, N-desethylhydroxychloroquine (DHCQ), in patients with systemic lupus erythematosus (SLE; lupus) receiving long-term oral HCQ treatment. SLE patients who had been taking HCQ for more than 3 months were recruited. Various clinical characteristics, laboratory values, and SLE Disease Activity Index (SLEDAI) scores were examined. The concentrations of HCQ and DHCQ ([HCQ] and [DHCQ]) were measured by liquid chromatography mass spectrometry, and the relationship between [HCQ], [DHCQ], and [HCQ]:[DHCQ] ratio to various factors was investigated. In total, 189 SLE patients receiving long-term HCQ treatment were included in the analysis. The median (interquartile range [IQR]) [HCQ] was 515 (IQR 353-720) ng/ml, the median [DHCQ] was 417 (IQR 266-591) ng/ml, and the median [HCQ]:[DHCQ] ratio was 1.3 (range 1.0-1.7). [HCQ] was closely associated with [DHCQ] (r = 0.81, P < 0.0001). The weight-adjusted oral HCQ dose was strongly associated with both [HCQ] (P < 0.001) and [DHCQ] (P < 0.001). Time since last dose was associated with [HCQ] (P < 0.001). No statistically significant association was found between renal function or smoking and [HCQ] or [DHCQ]. Use of additional immunosuppressants increased both [HCQ] and [DHCQ] after adjusting for possible confounders (P = 0.04 and P = 0.03, respectively). The lower SLEDAI score was significantly related to higher [HCQ], after adjusting for age, sex, weight-adjusted HCQ dose, time since last dose, number of other immunosuppressants, and smoking status (P = 0.007). Various factors affected blood levels of [HCQ], [DHCQ], or the [HCQ]:[DHCQ] ratio of SLE patients receiving long-term oral HCQ treatment. Notably, higher [HCQ] was associated with a lower SLEDAI score in our typical outpatient clinic population with lupus. © 2016, American College of Rheumatology.

St.-Hil., Lythraceae, a plant from the Cerrado known as pacari or dedaleiro, is widely used as an antipyretic, wound healing, anti-inflammatory, antidiarrheal and in the treatment of gastritis and cancer. Notable among the metabolite groups identified in leaves of L. pacari are the polyphenols, such as tannins and flavonoids, related to the pharmacological activities of pacari. Studies on the influence of environmental factors over production of major groups of secondary metabolites in pacari are important because they contribute data for its cultivation and harvest, and establish quantitative parameters of secondary metabolites in the plant drug. The objective of this study was to evaluate the influence of environmental factors on concentrations of phenolic metabolites in the leaves of L. pacari. Compounds quantified in the leaves were: total phenols, tannins by protein precipitation, hydrolysable tannins, total flavonoids, ellagic acid and mineral nutrients, while soil fertility was also analyzed, all over a period of one year. The data were analyzed using multivariate analysis, and the results suggest that metabolite concentrations in the leaves of this plant are influenced by seasonal factors, in particular the temperature and foliar micronutrients (Cu, Fe, Mn, Zn.

Decamethylcyclopentasiloxane (D(5)) is a volatile compound used in personal care products that is released to the atmosphere in large quantities. Although D(5) is currently under consideration for regulation, there have been no field investigations of its atmospheric fate. We employed a recently developed, quality assured method to measure D(5) concentration in ambient air at a rural site in Sweden. The samples were collected with daily resolution between January and June 2009. The D(5) concentration ranged from 0.3 to 9 ng m(-3), which is 1-3 orders of magnitude lower than previous reports. The measured data were compared with D(5) concentrations predicted using an atmospheric circulation model that included both OH radical and D(5) chemistry. The model was parametrized using emissions estimates and physical chemical properties determined in laboratory experiments. There was good agreement between the measured and modeled D(5) concentrations. The results show that D(5) is clearly subject to long-range atmospheric transport, but that it is also effectively removed from the atmosphere via phototransformation. Atmospheric deposition has little influence on the atmospheric fate. The good agreement between the model predictions and the field observations indicates that there is a good understanding of the major factors governing D(5) concentrations in the atmosphere.

2016-05-16

Purpose - The purpose of this paper is to discuss the lessons learnt from the process of implementing a new model of governance within Living Well, a New Zealand statutory mental health agency. Design/methodology/approach - It presents the findings from an organisational case study that involved qualitative interviews, meeting observations and document analysis. Archetype theory provided the analytical framework for the research enabling an analysis of both the formal structures and informal value systems that influenced the implementation of the governance model. Findings - The research found that the move to a new governance model did not proceed as planned. It highlighted the importance of staff commitment, the complexity of adopting a new philosophical approach and the undue influence of key personalities as key determining factors in the implementation process. The findings suggest that planners and managers within statutory mental health agencies need to consider the implications of any proposed governance change on existing roles and relationships, thinking strategically about how to secure professional commitment to change. Practical implications - There are ongoing pressures within statutory mental health agencies to improve the efficiency and effectiveness of organisational structures and systems. This paper has implications for how planners and managers think about the process of implementing new governance models within the statutory mental health environment in order to increase the likelihood of sustaining and embedding new approaches to service delivery. Originality/value - The paper presents insights into the process of implementing new governance models within a statutory mental health agency in New Zealand that has relevance for other jurisdictions.

Effects of Selected Corporate Governance Characteristics on Firm Performance: Empirical Evidence from Kenya

Directory of Open Access Journals (Sweden)

Vincent Okoth Ongore

2011-01-01

Full Text Available This paper examines the interrelations among ownership, board and manager characteristics and firm performance in a sample of 54 firms listed at the Nairobi Stock Exchange (NSE. These governance characteristics, designed to minimize agency problems between principals and agents are operationalized in terms of ownership concentration, ownership identity, board effectiveness and managerial discretion. The typical ownership identities at the NSE are government, foreign, institutional, manager and diverse ownership forms. Firm performance is measured using Return on Assets (ROA, Return on Equity (ROE and Dividend Yield (DY. Using PPMC, Logistic Regression and Stepwise Regression, the paper presents evidence of significant positive relationship between foreign, insider, institutional and diverse ownership forms, and firm performance. However, the relationship between ownership concentration and government, and firm performance was significantly negative. The role of boards was found to be of very little value, mainly due to lack of adherence to board member selection criteria. The results also show significant positive relationship between managerial discretion and performance. Collectively, these results are consistent with pertinent literature with regard to the implications of government, foreign, manager (insider and institutional ownership forms, but significantly differ concerning the effects of ownership concentration and diverse ownership on firm performance.

Full Text Available We investigate whether ownership concentration influences bank profitability in a developing country context. We focus on bank ownership concentration measured as the amount of direct equity held by a majority shareholder categorised into: high ownership concentration, moderate ownership concentration and disperse ownership. We find that banks with high ownership concentration have higher return on assets, higher net interest margin and higher recurring earning power while banks with dispersed ownership have lower return on assets but have higher return on equity. Also, higher cost efficiency improves the return on assets of widely-held banks and the return on equity of banks with moderate ownership. The findings have implications.

Through the critical application of social theory, this paper will scrutinise how the operations of risk management help to constitute midwives׳ understandings of childbirth in a particular way. Drawing from rich ethnographic data, collected in the southeast of England, the paper presents empirical evidence to critically explore how institutional concerns around risk and risk management impact upon the way midwives can legitimately imagine and manage labour and childbirth. Observational field notes, transcribed interviews with various midwives, along with material culture in the form of documentary evidence will be used to explore the unintended consequences of clinical governance and its risk management technologies. Through this analysis the fear factor of risk in midwifery talk and practice will be introduced to provide an insight into how risk management impacts midwifery practice in the UK. Copyright © 2016.

In order to verify if the concentration factors for dose calculations in critical population recommended by the International Atomic Energy (IAEA), on the Safety Series 57, are in agreement with local factors, studies were carried out at Piraquara de Dentro bay, a region in the vicinities of the Almirante Alvaro Alberto Nuclear Power Plant (CNAAA). Chromium, caesium, iron and cobalt concentration factors for corvine and shrimp were determined using the activation analysis method by neutrons, taking into account the same behaviour between radioactive and stable from the same physicochemical form. This study has evidenced that: The local values of cesium, iron and cobalt concentration factors for corvine (fish) are in the same order of magnitude of the IAEA recommended values; The chromium, caesium and cobalt concentration factor values determined for shrimp for Piraquara de Dentro bay are in the same order of magnitude or smaller than those proposed by IAEA, while the concentration factor value for ion is one order of magnitude higher than the IAEA recommended value.

The environmental and water-quality factors that affect concentrations of Escherichia coli (E. coli) in water and sediment were investigated at three public bathing beachesEdgewater Park, Villa Angela, and Sims Parkin the Cleveland, Ohio metropolitan area. This study was done to aid in the determination of safe recreational use and to help water- resource managers assess more quickly and accurately the degradation of recreational water quality. Water and lake-bottom sediments were collected and ancillary environmental data were compiled for 41 days from May through September 1997. Water samples were analyzed for E. coli concentrations, suspended sediment concentrations, and turbidity. Lake- bottom sediment samples from the beach area were analyzed for E. coli concentrations and percent dry weight. Concentrations of E. coli were higher and more variable at Sims Park than at Villa Angela or Edgewater Park; concentrations were lowest at Edgewater Park. Time-series plots showed that short-term storage (less than one week) of E. coli in lake-bottom sediments may have occurred, although no evidence for long-term storage was found during the sampling period. E. coli concentrations in water were found to increase with increasing wave height, but the resuspension of E. coli from lake-bottom sediments by wave action could not be adequately assessed; higherwave heights were often associated with the discharge of sewage containing E. coli during or after a rainfall and wastewater-treatment plant overflow. Multiple linear regression (MLR) was used to develop models to predict recreational water quality at the in water. The related variables included turbidity, antecedent rainfall, antecedent weighted rainfall, volumes of wastewater-treatment plant overflows and metered outfalls (composed of storm-water runoff and combined-sewer overflows), a resuspension index, and wave heights. For the beaches in this study, wind speed, wind direction, water temperature, and the prswimmers

Bretas, Nilo; Shimizu, Helena Eri

2017-04-01

This article analyzes governance in health regions, through the contributions of two studies: one on a governance model and the other on duties in the management of public policies networks. The former conducted a meta-analysis of 137 case studies in the literature on collaborative governance aimed at preparing an explanatory and analytical model. Authors identified critical variables that will influence the results: a previous history of conflict or cooperation, incentives for participation, power imbalances, leadership and institutional design. They also identified key factors: face-to-face dialogue, trust building and development of commitment and shared vision. The latter study examined networks of public policies in the analytic tradition and the perspective of governance, incorporating concepts from the field of political science, economics and interorganizational relations, in order to support the management of public policies networks. The study identified network management as equivalent to a strategic game involving functions: network activation, framework of relations, intermediation, facilitation and consensus building and mediation and arbitration. The combination of the two reflections provides a conceptual reference for better understanding of governance in health regions.

Arab countries face the corruption issues in its several public organizations. The corruption in these countries is considered as the main challenge. The oil sector is one of the public sectors that have huge level of corruption. However, the Iraqi economy had become dependable on oil sector daring the last three decades, and on the contrary, of what other oil countries did. The capital is considered as one of the essential factor for economic development. The revenues of oil exports will stay the essential source for economic development in Iraq in the future in order to reduce being dependable on oil. Since the beginning of the 3rd thousands, the world witnessed great rise in the demand on oil, but the Iraqi exports of crude oil come to be less than its similarities in the seventeenths of last century. So our oil sector is still in need of deep study. This study focuses on technological technique that can make huge decrease for corruption in oil sector in Iraq. However, e-government is considered as the best techniques that can decrease the corruption. Thus, this study bases on challenges that effect on build successful e-government project in Iraqi oil industry.

Full Text Available Uric acid is the end product of purine metabolism in humans, and increased serum uric acid concentrations lead to gout. The objective of the current study was to identify factors that are independently associated with serum uric acid concentrations in a cohort of Czech control individuals.The cohort consisted of 589 healthy subjects aged 18-65 years. We studied the associations between the serum uric acid concentration and the following: (i demographic, anthropometric and other variables previously reported to be associated with serum uric acid concentrations; (ii the presence of metabolic syndrome and the levels of metabolic syndrome components; and (iii selected genetic variants of the MTHFR (c.665C>T, c.1286A>C, SLC2A9 (c.844G>A, c.881G>A and ABCG2 genes (c.421C>A. A backward model selection procedure was used to build two multiple linear regression models; in the second model, the number of metabolic syndrome criteria that were met replaced the metabolic syndrome-related variables.The models had coefficients of determination of 0.59 and 0.53. The serum uric acid concentration strongly correlated with conventional determinants including male sex, and with metabolic syndrome-related variables. In the simplified second model, the serum uric acid concentration positively correlated with the number of metabolic syndrome criteria that were met, and this model retained the explanatory power of the first model. Moderate wine drinking did not increase serum uric acid concentrations, and the urate transporter ABCG2, unlike MTHFR, was a genetic determinant of serum uric acid concentrations.Metabolic syndrome, moderate wine drinking and the c.421C>A variant in the ABCG gene are independently associated with the serum uric acid concentration. Our model indicates that uric acid should be clinically monitored in persons with metabolic syndrome.

Choline concentrations in human erythrocytes increase after freezing and thawing, during incubation in Krebs-phosphate for 30 min or on storage at 0 degrees C for 3-24 hr. The increase is prevented by protein precipitation by 10% perchloric acid, 10% zinc hydroxide, 10% sodium tungstate or boiling in water. It is not prevented by EDTA (10 mM) and is increased by oleate (5 mM). We suggest that the increase is due to the action of phospholipase D on erythrocyte phospholipids.

Due to their high resistance to inactivation procedures, nonenveloped viruses such as parvovirus B19, human bocavirus (HBoV), human parvovirus 4 (PARV4), hepatitis A (HAV) and hepatitis E virus (HEV) pose a particular threat to blood products. Virus transmission to patients treated with blood products presents an additional burden to disease. We determined the frequency and the amount of nucleic acid specific for nonenveloped viruses in recently manufactured preparations of commercial coagulation factor concentrates. At least three different batches of each of 13 different plasma-derived and recombinant coagulation factor products were tested for the presence and the amount of nucleic acid for parvovirus B19, HBoV, human parvovirus 4, hepatitis A virus and HEV by using quantitative polymerase chain reaction. Whereas none of the recombinant products tested positive for any of these viruses, parvovirus B19 DNA with amounts ranging between 2×10(1) and 1.3×10(3) genome equivalents/ml was detected in five plasma-derived products. In addition to parvovirus B19 genotype 1, genotypes 2 and 3 were observed in two batches of a factor VIII/von-Willebrand factor product. In two products (one factor VIII concentrate and one activated prothrombin complex concentrate), a combination of both genotypes 1 and 2 of parvovirus B19 was detected. The data show that nucleic acids from several relevant nonenveloped viruses are not found at detectable levels in coagulation factor concentrates. In some cases, parvovirus B19 DNA was detectable at low levels. Testing of the plasma pools for the full range of parvovirus genotypes is advocated for ensuring product safety. © 2010 The Author(s).

A selection of wild animals was sampled in the winter of 1986/87. The sites chosen for sampling were based on information obtained from surveys carried out by The Institute of Terrestrial Ecology in the spring and autumn of 1986. Animals included deer, grouse, hares and rabbits, and foxes which were collected as a top carnivore in the food chain. Variation in concentration of caesium between species from the same area was unpredictable; rabbits never exceeded 200 Bq kg -1 (fresh wt) of 137 Cs in their flesh, even when adjacent to deer forests with over 1000 Bq kg -1 in the venison. The greatest complication arose from areas of peaty uplands where the pre-Chernobyl 137 Cs from weapons-testing was much higher than expected. This pre-Chernobyl contribution amounted to 630 Bq kg -1 in a red grouse from the Pennines, and 650 Bq kg -1 in a roe deer from near the Borders, being c. 60% of the total. Significant differences in concentration factors were found depending on species, food, sex, breeding condition and age. Contrasting the decrease of the two caesium isotopes in roe deer from forestry on peat with those from woodlands on mineral soils, it appeared that after an initial fall in concentration, the only decrease thereafter occurred on the mineral soils. Nowhere were radiocaesium concentrations high enough to cause concern amongst consumers of game and other wild animals, even when levels exceed 3000 Bq kg -1 (fresh wt) as they did in red deer, red grouse and the blue hare.

National public health associations (PHAs) are key partners with governments and communities to improve, protect and promote the public's health. Governance and organizational capacity are among the key determinants of a PHA's effectiveness as an advocate for appropriate public health policies and practice. During 2014, the World Federation of Public Health Associations (WFPHA) conducted an on-line survey of its 82 PHA members, to identify the state of organizational governance of national public health associations, as well as the factors that influence optimal organizational governance. The survey consisted of 13 questions and focused on the main elements of organizational governance: cultivating accountability; engaging stakeholders; setting shared direction; stewarding resources; and, continuous governance enhancement. Four questions included a qualitative open-ended response for additional comments. The survey data were analyzed using Microsoft Excel. The qualitative data was analyzed using thematic content analysis Responses were received from 62 PHAs, constituting a 75.6 % response rate. The two most important factors that support governance effectiveness were a high degree of integrity and ethical behavior of the PHA's leaders (77 %) and the competence of people serving on the PHA's governing body (76 %). The lack of financial resources was considered as the most important factor that negatively affected organizational governance effectiveness (73 %). The lack of mentoring for future PHA leaders; ineffective or incompetent leadership; lack of understanding about good governance practices; and lack of accurate information for strategic planning were identified as factors influencing PHA governance effectiveness. Critical elements for PHA sustainability included diversity, gender-responsiveness and inclusive governance practices, and strategies to build the future generation of public health leaders. National PHA have a responsibility to put into place

Steady-state metabolite concentrations reflect a balance between maximizing enzyme efficiency and minimizing total metabolite load.

Full Text Available Steady-state metabolite concentrations in a microorganism typically span several orders of magnitude. The underlying principles governing these concentrations remain poorly understood. Here, we hypothesize that observed variation can be explained in terms of a compromise between factors that favor minimizing metabolite pool sizes (e.g. limited solvent capacity and the need to effectively utilize existing enzymes. The latter requires adequate thermodynamic driving force in metabolic reactions so that forward flux substantially exceeds reverse flux. To test this hypothesis, we developed a method, metabolic tug-of-war (mTOW, which computes steady-state metabolite concentrations in microorganisms on a genome-scale. mTOW is shown to explain up to 55% of the observed variation in measured metabolite concentrations in E. coli and C. acetobutylicum across various growth media. Our approach, based strictly on first thermodynamic principles, is the first method that successfully predicts high-throughput metabolite concentration data in bacteria across conditions.

Dependence of soil-to-plant transfer factors of elements on their concentrations in soil

Tsukada, Hirofumi; Watabe, Teruhisa.

1996-01-01

Transfer factors (TFs) of 31 stable elements from soil to plant were determined by neutron activation analysis. Soil and plant samples were collected from 112 farm fields in Aomori prefecture, Japan. The elements described are those that could be detected by this method, which include essential elements for plant growth and nonessential elements. Several of these elements were divided into two groups, each having different TF characteristics. In the first group of elements there was an inverse correlation between the TFs and the soil concentrations of the elements, especially for Cl, K and Ca. The concentrations of these elements in plants were independent of their soil concentrations. However, in the second group, especially Sc and Co, the TFs were independent of the soil concentrations of the elements. The fluctuation of TFs observed in this study was smaller than that previously reported. This may be attributed to the relatively narrow geographic area of the present study. In addition, the TFs for the stable elements in this study were generally one to three orders of magnitude lower than those compiled for radioactive isotopes in previous publications. (author)

Full Text Available The Gradual collapse of financial markets in the European Union since the fall of 2008 and economic crises at the credits portfolio level that followed, were generated by the several factors, often interdependent, both macroeconomic and microeconomic level, finally leading to the accumulation of excessive risk in the financial system. This excessive risk was partially caused by the deficiencies in Corporate Governance of the Financial Institutions and the especially banks deficiencies. Even if we can’t put down to the Corporate Governance crisis started, yet nonexistent or inadequacy of effective control mechanisms have determined to the excessive risk-taking by most credit institutions. This article aims to evaluate the application of Corporate Governance principles of the significant players within the Romanian banking system. The research methodology was based essentially on the technique of using the questionnaire, on Corporate Governance documents remarks published on the banks analyzed websites and on the using scoring methods in evaluating the application of Corporate Governance principles.

Impacts of government and market on firm’s efforts to reduce pollution

Directory of Open Access Journals (Sweden)

Bowon Kim

2015-12-01

Full Text Available We examine how the government and the market affect firm’s pollution abatement efforts, i.e. firm’s efforts to reduce its pollution emission. The way for the government to control firm’s pollution is to impose penalty, whereas the consumers (the market make their purchasing decision by taking into account the pollution, i.e. the demand is affected by the stock of pollution. In effect, we consider two forces, government penalty and consumer’s sensitivity to pollution, as primary factors to control firm’s pollution and analyze their interaction in relation to the firm’s pollution reduction efforts. The analysis suggests as follows. The government penalty and the consumer’s awareness are substitutes either (1 when the market size is relatively large or (2 when the market is relatively small, but the government penalty is relatively heavy. On the contrary, the two factors are complements when the market size is relatively small and the government penalty is relatively light. We discuss managerial and economic implications of the analysis results.

MILK WITH INCREASED CONCENTRATION OF MELATONIN PACKAGING FACTORS ON CONSUMER PURCHASE INTENTION

Directory of Open Access Journals (Sweden)

Maria Patricia Milagres

2014-02-01

Full Text Available The conjoint analysis of factors was used employed to develop a label for the packaging of milk with increased concentration of melatonin. Three factors were selected with three or two levels for the assembly of packaging: packaging design (“blue design with stars and pouring milk”, “white without drawing” and “blue stars with and without drawing”, name (“milk night “and” melatonin “ and informative text about getting natural melatonin by night milking, and the benefits of this compound (“with” and “without”. Twelve packaging designs were created based on a complete factorial arrangement. The designs were presented to 144 consumers who were asked to assess purchase intent of each package. For the joint analysis of factors, the ideal product or more likely to purchase for the most consumers would be blue with stars and packaging design of milk pouring, named milk night and in the presence of informational text, demonstrating that consumers like a package that brings the product and that contains information described. Therefore, the packaging has a major influence on consumer choice and can contribute positively or negatively to the acceptance of food.

This study was conducted to confirm sporadic measurements made over the late 1970s to the early 1990s which determined that mercury (Hg) concentrations were low in anadromous char across Arctic and subarctic Canada including northern Québec and Labrador. Over 2004–2013, anadromous char populations across northern Canada were investigated at 20 sites for Hg concentrations and life history characteristics. Hg concentrations were extremely low in anadromous char muscle, typically < 0.05 μg/g (wet weight) and, at each location, generally increased with fish length, age and nitrogen isotope (δ{sup 15}N) ratio and decreased with condition factor and %lipid; correlations with carbon isotope (δ{sup 13}C) ratio were inconsistent. Location and year were significant variables influencing Hg concentrations over the study area; longitude and latitude also were significant influencing variables. Char length, weight, age, condition factor and lipid content explained additional variance. A tendency towards higher Hg concentrations with increasing latitude may be partially related to decreasing growth of char towards the north. However, Hg concentrations in char were positively correlated with growth rates suggesting that Hg concentrations in char also were higher in the more productive study areas, including to the west where mainland riverine inputs of terrestrial carbon, nutrients, and Hg were greater. The data base for assessing time trends in char was limited by the small number of years investigated at most locations, variable fish size across years, small sample size, etc. Where temporal trends were detected, they were of increase on the long term (1970s, 1980s or early 1990s to the present) but of decrease on the short term (early 2000s to present) with Nain (Labrador) showing the converse pattern. Higher Hg concentrations were also related to lower condition factor and cooler springs. Hg concentrations in anadromous char are compared with other terrestrial, aquatic

Ethical and legal challenges in bioenergy governance: Coping with value disagreement and regulatory complexity

International Nuclear Information System (INIS)

Gamborg, Christian; Anker, Helle Tegner; Sandøe, Peter

2014-01-01

The article focuses on the interplay between two factors giving rise to friction in bioenergy governance: profound value disagreements (e.g. the prioritizing of carbon concerns like worries over GHG emissions savings over non-carbon related concerns) and regulatory complexity (in terms of regulatory measures and options). We present ethical and legal analyses of the current stalemate on bioenergy governance in the EU using two illustrative cases: liquid biofuels for transport and solid biomass-based bioenergy. The two cases disclose some similarities between these two factors, but the remaining differences may partly explain, or justify, contrasting forms of governance. While there seems to be no easy way in which the EU and national governments can deal with the multiple sustainability issues raised by bioenergy, it is argued that failure to deal explicitly with the underlying value disagreements, or to make apparent the regulatory complexity, clouds the issue of how to move forward with governance of bioenergy. We suggest that governance should be shaped with greater focus on the role of value disagreements and regulatory complexity. There is a need for more openness and transparency about such factors, and about the inherent trade-offs in bioenergy governance. - Highlights: • Ethical and legal challenges in governance of liquid biofuels and wood pellets. • EU sustainability criteria legal and ethical analysis—EU bioenergy policy options. • Analysis of interplay between carbon and non-carbon concerns and regulatory options. • Governance must cope with value disagreement and regulatory complexity

Economic governance in the Chinese PV industry: Structural and individual factors influencing market development

Directory of Open Access Journals (Sweden)

Gruss, Laura

2015-03-01

Full Text Available Since the beginning of the new millennium, the global production of photovoltaic (PV modules has been experiencing a rapid growth. In 2008, China already had 50 times more producers than in 2001 and three Chinese companies ranked amongst the top 10 PV producers worldwide. However, overcapacities and international trade disputes have challenged the success story of the Chinese PV industry. In order to try to tackle the mechanisms which have fostered the overall development of the Chinese PV industry since the 2000s, I have conducted a qualitative case study on Chinese PV modules producers. Following the logic of a qualitative research design, theories on cluster development have been used as an analytical device for structuring the causal narrative. In a circular research process design, structural factors, such as local growth fetishism and rebalancing, as well as individual factors, such as herd behaviour and wishful thinking, have been identified as drivers along the line of the life cycle of clusters. In this respect, this paper contests the still popular idea of the Chinese central government as the omnipotent and rational director of the Chinese economy and takes the consequences of past decentralization policies as well as bounded rationality into consideration. Since the political emphasis of regional development for global competitiveness had similar policy effects in different countries, the findings call for a context sensitive comparison between industries and countries.

Factors influencing liver PCB concentrations in sparrowhawks (Accipiter nisus), kestrels (Falco tinnunculus) and herons (Ardea cinerea) in Britain

Energy Technology Data Exchange (ETDEWEB)

Wienburg, Claire L.; Shore, Richard F

2004-11-01

Large scale temporal and spatial changes in the exposure of terrestrial vertebrates to PCBs have been monitored in the UK by measuring liver residues in sparrowhawks (Accipiter nisus), kestrels (Falco tinnunculus) and grey herons (Ardea cinerea) from throughout the country. Residues in the three species are typically characterised by large intra- and inter-specific variation. Data for 306 sparrowhawks, 186 kestrels and 47 herons collected between 1992 and 1997 as part of a national Predatory Bird Monitoring Scheme were examined to determine how much of this variation was explained by body condition, age and sex, rather than other factors. In all three species, body condition was the single most important factor and accounted for up to 49% of the variation in PCB liver residues; starved birds had the highest liver concentrations. Age and sex were also significant but of lesser importance. Adult sparrowhawks and kestrels had liver PCB residues that were 2 to 10-fold higher than in first-year birds. Sex did not affect residue magnitude in a consistent manner. PCB concentrations in the liver were higher in males than females in both first-year and adult kestrels and in first-year sparrowhawks, but adult female sparrowhawks had similar PCB residues to adult males. Liver residues also varied seasonally. PCB concentrations in first-year sparrowhawks increased during the first year following fledging and a similar pattern was detected in adult female sparrowhawks following egg laying. When these physiological factors were taken into account, it was evident that while kestrels with high fat scores had significantly lower PCB concentrations than either sparrowhawks or herons, liver residues were similar in all three species when birds were in a starved condition. Overall during 1992-1997, the combined influence of body condition, age and sex explained more of the variation in liver PCB concentrations than species differences or other factors, such as geographical variation

An activated Factor VII (FVIIa) concentrate, prepared from human plasma on a large scale, has to date not been available for clinical use for haemophiliacs with antibodies against FVIII and FIX. In the present study, we attempted to establish a large-scale manufacturing process to obtain plasma-derived FVIIa concentrate with high recovery and safety, and to characterize its biochemical and biological properties. FVII was purified from human cryoprecipitate-poor plasma, by a combination of anion exchange and immunoaffinity chromatography, using Ca2+-dependent anti-FVII monoclonal antibody. To activate FVII, a FVII preparation that was nanofiltered using a Bemberg Microporous Membrane-15 nm was partially converted to FVIIa by autoactivation on an anion-exchange resin. The residual FVII in the FVII and FVIIa mixture was completely activated by further incubating the mixture in the presence of Ca2+ for 18 h at 10 degrees C, without any additional activators. For preparation of the FVIIa concentrate, after dialysis of FVIIa against 20 mm citrate, pH 6.9, containing 13 mm glycine and 240 mm NaCl, the FVIIa preparation was supplemented with 2.5% human albumin (which was first pasteurized at 60 degrees C for 10 h) and lyophilized in vials. To inactivate viruses contaminating the FVIIa concentrate, the lyophilized product was further heated at 65 degrees C for 96 h in a water bath. Total recovery of FVII from 15 000 l of plasma was approximately 40%, and the FVII preparation was fully converted to FVIIa with trace amounts of degraded products (FVIIabeta and FVIIagamma). The specific activity of the FVIIa was approximately 40 U/ micro g. Furthermore, virus-spiking tests demonstrated that immunoaffinity chromatography, nanofiltration and dry-heating effectively removed and inactivated the spiked viruses in the FVIIa. These results indicated that the FVIIa concentrate had both high specific activity and safety. We established a large-scale manufacturing process of human plasma

The number of patients on antithrombotic treatment due to atrial fibrillation and venous thromboembolism is increasing fast due to an aging population. A growing proportion will be treated with novel oral anticoagulants, the first in clinical use was the direct oral thrombin inhibitor dabigatran (Pradaxa®). A small percentage of the patients on dabigatran will experience serious bleeding or be in need of urgent surgery. The aim of this study was to test the effects of different hemostatic agents in potentially reversing the anticoagulant effects in vitro in blood or platelet-rich plasma (PRP) spiked with dabigatran. Whole blood or PRP was spiked with the active substance dabigatran, 200 μg/L. We measured clotting time being induced by 1.4 pmol/L tissue factor using the instrument ReoRox2™ and initial clot growth velocity from a tissue factor covered surface using the instrument Thrombodynamics Analyzer T-2™. Dabigatran prolonged clotting time 5-fold but reduced clot growth velocity only slightly. The reversing effects of prothrombin complex concentrates (PCC), activated PCC (APCC) and recombinant activated factor VII (rFVIIa) were then tested. APCC (1.8 U/mL) reduced the prolonged clotting time by 1/3, rFVIIa (2 μg/L) only slightly (n = 10-20). The reduction was not significant using Mann-Whitney test but significant using t-test with Bonferronis' correction for multiple comparisons, whereas PCC (0.56 U/mL) had no effect on clotting time. APCC doubled initial clot growth velocity, although even more in the absence of dabigatran. In conclusion, APCC and rFVIIa, but not PCC, seem to reverse, at least partially, some effects of dabigatran on coagulation parameters. Systematic evaluation of case reports, registries and, ultimately, randomized clinical trials are needed to elucidate potential benefit for patients. Copyright © 2014 Elsevier Ltd.

Project governance: selected South African government experiments

2008-07-01

Full Text Available Some form of accountability and power structure binds all organisations. Such structures are typically referred to as the “governance” structure of the organisation. In organisations that have relatively mature project applications and methodologies in place, governance mechanisms are established on more permanent bases. With its focus on performance, results and outcomes, project governance establishes decision-making structures, as well as accountability and responsibility mechanisms in public institutions to oversee projects. As government institutions increasingly place emphasis on project applications for policy implementation and service delivery initiatives, mechanisms or structures should be established to facilitate clear interfaces between the permanent organisation and the temporary project organisation. Such mechanisms or structures should enhance the governance of projects, that is, the strategic alignment of projects, the decentralisation of decision- making powers, rapid resource allocation, and the participation of external stakeholders. The purpose of this article is to explore the concept “project governance”, and to highlight examples of project governance as applied in selected government departments in provincial and national spheres. This would enable the establishment of best practice examples and assist to develop benchmarks for effective project applications for service delivery improvement.

The effects of meteorological factors on airborne fungal spore concentration in two areas differing in urbanisation level

Science.gov (United States)

Oliveira, M.; Ribeiro, H.; Delgado, J. L.; Abreu, I.

2009-01-01

Although fungal spores are an ever-present component of the atmosphere throughout the year, their concentration oscillates widely. This work aims to establish correlations between fungal spore concentrations in Porto and Amares and meteorological data. The seasonal distribution of fungal spores was studied continuously (2005-2007) using volumetric spore traps. To determine the effect of meteorological factors (temperature, relative humidity and rainfall) on spore concentration, the Spearman rank correlation test was used. In both locations, the most abundant fungal spores were Cladosporium, Agaricus, Agrocybe, Alternaria and Aspergillus/Penicillium, the highest concentrations being found during summer and autumn. In the present study, with the exception of Coprinus and Pleospora, spore concentrations were higher in the rural area than in the urban location. Among the selected spore types, spring-autumn spores ( Coprinus, Didymella, Leptosphaeria and Pleospora) exhibited negative correlations with temperature and positive correlations both with relative humidity and rainfall level. On the contrary, late spring-early summer (Smuts) and summer spores ( Alternaria, Cladosporium, Epicoccum, Ganoderma, Stemphylium and Ustilago) exhibited positive correlations with temperature and negative correlations both with relative humidity and rainfall level. Rust, a frequent spore type during summer, had a positive correlation with temperature. Aspergillus/Penicillium, showed no correlation with the meteorological factors analysed. This knowledge can be useful for agriculture, allowing more efficient and reliable application of pesticides, and for human health, by improving the diagnosis and treatment of respiratory allergic disease.

Insulin-like growth factor-I (IGF-I) stimulates ovarian androgen production. Insulin-like growth factor binding protein-1 (IGFBP-1) inhibits IGF actions in vitro. To investigate the effect of oral contraceptive (OC) pills, given for 3 months, on serum gonadotropin, androgen, IGF-I, and IGFBP-1 concentrations, and glucose tolerance in seven women with polycystic ovarian disease (PCOD) and in five healthy control subjects. Seven women with PCOD and five healthy control subjects. An oral glucose tolerance test (OGTT) was performed before and after treatment with OC. After treatment with OC, serum luteinizing hormone, androstenedione, and free testosterone levels decreased, and sex hormone-binding globulin concentration increased in the women with PCOD as well as in the control subjects. The cumulative response of serum insulin to OGTT was larger in the women with PCOD than in the control subjects both before and after treatment. Serum IGF-I concentration, which was unchanged during OGTT, decreased from basal level of 326 +/- 70 micrograms/L to 199 +/- 28 micrograms/L after treatment with OC in the women with PCOD, whereas no change was found in the control subjects (from 235 +/- 11 micrograms/L to 226 +/- 11 micrograms/L). Treatment with OC caused an increase of the mean basal IGFBP-1 concentration from 24 +/- 7 micrograms/L to 73 +/- 14 micrograms/L in the women with PCOD. This increase was constant during the OGTT. In the control subjects, treatment with OC did not result in any significant change in IGFBP-1 concentrations (from 44 +/- 11 micrograms/L to 61 +/- 9 micrograms/L). The combination of decreased total IGF-I concentration and increased IGFBP-1 concentration induced by OC may decrease ovarian androgen production in PCOD.

In his review of the management of the environment and sustainable development within the federal government, the Commissioner stressed the importance of defining clearly of 'who does what' and identified a variety of mechanisms government departments have at their disposal to work together. These mechanisms range from the creation of new organizations to cost sharing agreements to voluntary networks for information exchange. Six case studies are described in detail designed to examine the key factors that could affect the success of such mechanisms. These factors include managing the effects of participant turnover, ensuring the continuity of departmental incentives, and paying attention to results of monitoring and evaluation to learn from past experience. It is suggested that since other than persuasion and negotiation, interdepartmental cooperation is limited by departments' inability to compel other departments to act, the primary central agencies, such as the Privy Council Office and the Treasury Board Secretariat must play a crucial leadership role in achieving a 'Government of Canada' perspective.

Full Text Available Corporate governance reforms are occurring in countries around the globe and potentially impacting the population of the entire planet. In developing countries, such reforms occur in a larger context that is primarily defined by previous attempts at promoting “development” and recent processes of economic globalization. In this context, corporate governance reforms (in combination with the liberalising reforms associated with economic globalization, in effect represent a new development strategy for third world countries. The most basic questions that arise with respect to this situation are what the prospects for this new development model are and whether alternatives should be considered.

As physicochemical properties of the soil highly influence the bioavailable fraction of a particular trace metal, measured metal body burdens in a particular species are often assumed to be more reliable estimators of the contamination of the biota. To test this we compared the Cd, Cu and Zn content of three spiders (generalist predators) and two amphipods (detritivores), co-occurring in seven tidal marshes along the river Schelde, between each other and with the total metal concentrations and the concentrations of four sequential extractions of the soils. Correlations were significant in only one case and significant sitexspecies interactions for all metals demonstrate that factors affecting metal concentration were species and site specific and not solely determined by site specific characteristics. These results emphasize that site and species specific biological factors might be of the utmost importance in determining the contamination of the biota, at least for higher trophic levels. A hypothetical example clarifies these findings. - Site and species specific biological factors are important in determining contamination of biota.

Governance or Governing – the Missing Link?

Directory of Open Access Journals (Sweden)

Full Text Available Governance and governing are two distinct concepts, but they intertwine. “Good governing” exercises good influence on development. “Good governance” supposes first a relationship of power focused on a series of reforms structured at three levels: the political – administrative level, the economic level, and the level of civil society. As this dimension is difficult to measure, the qualitative evaluation of the governing act raised the interest of the World Bank researchers, who elaborated and monitored the dynamics of a set of indicators, which includes six major dimensions of the governing. A retrospective concerning the image of governing in Romania during the period from 1996 to 2005 suggests a modest increase of the score: from -0.138 (1996 to 0.008 (2002; that was partially achieved based on the voice and responsibility index and on the political stability index, not on those that measure more directly the administrative performance or the integrity of the governing act. For a comparative study, we chose seven countries for the purposes of analysis (two new European Union member states: Romania and Bulgaria; two older member countries of the European Union: Slovenia and Latvia; three non-member states: Moldova, Ukraine, and Georgia, which reveal the quality of the governing from a comparative perspective. Corruption control completes the image created by the analyzed indicators. The mere formal accomplishment of commitments made in the pre-accession activity, doubled by recent internal evolutions, bring doubts about the credibility of the anticorruption reforms, as Romania continues to be considered the country with the highest CPI in the European Union. The pessimism of public opinion and the fact that only 34% of the Romanian people consider that the level of corruption will decrease in the following three years constitutes an alarm signal addressed to the governance, in view of the real reformation of the administration system

The major concern of linezolid is the adverse events. High linezolid trough serum concentration (Cmin) has been associated with toxicity. The aim of this study was to analyze factors associated with high Cmin. Main clinical characteristics of 104 patients treated with 600 mg/12 hours of linezolid were retrospectively reviewed. Samples were obtained just before the next dose after at least three doses and within the first 8 days of treatment. High Cmin was considered when it was >8 mg/L. Univariate and multivariate analysis were performed. 34.6% patients had a Cmin >8 mg/L, and they were older and had more frequently an estimated glomerular filtration by MDRD 8 was the renal function. Patients with an eGF 80 mL/min (OR: 4.273) and there was a trend towards a high Cmin in patients with eGF between 40-80 mL/min (OR: 2.109). High Cmin were frequent, especially in patients with MDRD <40 mL/min. Therapeutic drug monitoring could be useful to avoid toxicity in patients with renal dysfunction.

Plural governance is a form of governance where a firm both makes and buys similar goods or services. Despite a widespread use of plural governance there are no transaction cost models of how plural governance affects performance. This paper reviews the literature about plural forms and proposes...... a model relating transaction cost and resource-based variables to the cost of the plural form. The model is then used to analyze when the plural form is efficient compared to alternative governance structures. We also use the model to discuss the strength of three plural form synergies....

To compare outcomes following inactive prothrombin complex concentrate (PCC) or recombinant activated factor VII (rFVIIa) administration during cardiac surgery. Retrospective propensity-matched analysis. Academic tertiary-care center. Patients undergoing cardiac surgery requiring cardiopulmonary bypass who received either rFVIIa or the inactive 3-factor PCC. Outcomes following intraoperative administration of rFVIIa (263) or factor IX complex (72) as rescue therapy to treat bleeding. In the 24 hours after surgery, propensity-matched patients receiving PCC versus rFVIIa had significantly less chest tube outputs (median difference -464 mL, 95% confidence interval [CI] -819 mL to -110 mL), fresh frozen plasma transfusion rates (17% v 38%, p = 0.028), and platelet transfusion rates (26% v 49%, p = 0.027). There were no significant differences between propensity-matched groups in postoperative stroke, deep venous thrombosis, pulmonary embolism, myocardial infarction, or intracardiac thrombus. Postoperative dialysis was significantly less likely in patients administered PCC versus rFVIIa following propensity matching (odds ratio = 0.3, 95% CI 0.1-0.7). No significant difference in 30-day mortality in patients receiving PCC versus rFVIIa was present following propensity matching. Use of rFVIIa versus inactive PCCs was significantly associated with renal failure requiring dialysis and increased postoperative bleeding and transfusions. Copyright © 2018 Elsevier Inc.

According to the program approved by the Government of Russia the AES-2006 design intended as a base one for the beginning of realization of the plans on development of the nuclear power engineering of Russia in the near future has been under way now. The most crucial components of the reactor plant are certainly the core and its basic component - FA. In the FA design such factors are concentrated that mainly define safety, profitability, adaptability to manufacture and operation of the fuel and NPP as a whole. As the nearest prototype for AES-2006 the TVS-2M design used at the Balakovo NPP is taken. The report shows on the basis of qualitative and quantitative evaluation that design of TVS-2 and its modifications TVS-2M are in the best compliance with the requirements of the project of the new RP AES-2006. This compliance is confirmed by the operational experience of the basic variant of the design

The Role of Local Government in Evictions

J van Wyk

2011-06-01

Full Text Available Local government occupies a unique place in the South African system of government. This is circumscribed by the Constitution which contains directives. Enjoining municipalities inter alia to provide democratic and accountable government for local communities and to promote social and economic development (section 152 as well as to undertake developmentally-oriented planning (section 153. In addition local government has a specific role to play regarding access to adequate housing and, in that context, evictions. In terms of sections 25 and 26 of the Constitution as well as legislation enacted in terms of these provisions new and different procedures have been put in place to demarcate the role of municipalities in evictions. The interpretation, by the courts, of these legislative provisions, has created a framework within which municipalities must react to and deal with evictions. In terms of that framework a number of duties and responsibilities are placed on municipalities, which include that they do the following: have policies, actions and programmes in place, draw up proper housing plans, be notified of evictions, mediate and engage with all stakeholders and provide temporary - and suitable alternative - accommodation of a specific standard, all of which must be consistent with principles of human dignity and be reasonable. Against this background this paper will interrogate the role of local government in evictions, concentrating on the constitutional directives for municipalities, the different eviction procedures and the duties and responsibilities of municipalities.

Full Text Available Abstract Background National public health associations (PHAs are key partners with governments and communities to improve, protect and promote the public’s health. Governance and organizational capacity are among the key determinants of a PHA’s effectiveness as an advocate for appropriate public health policies and practice. Methods During 2014, the World Federation of Public Health Associations (WFPHA conducted an on-line survey of its 82 PHA members, to identify the state of organizational governance of national public health associations, as well as the factors that influence optimal organizational governance. The survey consisted of 13 questions and focused on the main elements of organizational governance: cultivating accountability; engaging stakeholders; setting shared direction; stewarding resources; and, continuous governance enhancement. Four questions included a qualitative open-ended response for additional comments. The survey data were analyzed using Microsoft Excel. The qualitative data was analyzed using thematic content analysis Results Responses were received from 62 PHAs, constituting a 75.6 % response rate. The two most important factors that support governance effectiveness were a high degree of integrity and ethical behavior of the PHA’s leaders (77 % and the competence of people serving on the PHA’s governing body (76 %. The lack of financial resources was considered as the most important factor that negatively affected organizational governance effectiveness (73 %. The lack of mentoring for future PHA leaders; ineffective or incompetent leadership; lack of understanding about good governance practices; and lack of accurate information for strategic planning were identified as factors influencing PHA governance effectiveness. Critical elements for PHA sustainability included diversity, gender-responsiveness and inclusive governance practices, and strategies to build the future generation of public health

Governing Forest Ecosystem Services for Sustainable Environmental Governance: A Review

Directory of Open Access Journals (Sweden)

Shankar Adhikari

2018-05-01

Full Text Available Governing forest ecosystem services as a forest socio-ecological system is an evolving concept in the face of different environmental and social challenges. Therefore, different modes of ecosystem governance such as hierarchical, scientific–technical, and adaptive–collaborative governance have been developed. Although each form of governance offers important features, no one form on its own is sufficient to attain sustainable environmental governance (SEG. Thus, the blending of important features of each mode of governance could contribute to SEG, through a combination of both hierarchical and collaborative governance systems supported by scientifically and technically aided knowledge. This should be further reinforced by the broad engagement of stakeholders to ensure the improved well-being of both ecosystems and humans. Some form of governance and forest management measures, including sustainable forest management, forest certification, and payment for ecosystem services mechanisms, are also contributing to that end. While issues around commodification and putting a price on nature are still contested due to the complex relationship between different services, if these limitations are taken into account, the governance of forest ecosystem services will serve as a means of effective environmental governance and the sustainable management of forest resources. Therefore, forest ecosystem services governance has a promising future for SEG, provided limitations are tackled with due care in future governance endeavors.

Total flavonoid concentrations of bryophytes from Tianmu Mountain, Zhejiang Province (China: Phylogeny and ecological factors.

Directory of Open Access Journals (Sweden)

Xin Wang

Full Text Available The flavonoids in bryophytes may have great significance in phylogeny and metabolism research. However, to date there has been little research on bryophyte metabolites, especially flavonoids. To redress this somewhat, we determined flavonoid concentrations of bryophytes from Tianmu Mountain through a colorimetric assay and considered the factors influencing the results. This is the first time that the flavonoid contents of bryophytes have been examined in detail. The results revealed a range of total flavonoid concentrations in 90 samples collected from Tianmu Mountain from 1.8 to 22.3 mg/g (w/w. The total flavonoid contents of liverworts were generally higher than those of mosses; acrocarpous mosses had generally higher values than that of pleurocarpous mosses. The total flavonoid contents of bryophytes growing at lower light levels were general higher than those growing in full-sun. The total flavonoid contents of epiphytic bryophytes were highest, while those of aquatic bryophytes were the lowest. Total flavonoid contents of species growing at low-latitudes were much higher than those at high-latitude individuals. In conclusion, total flavonoid contents of bryophytes have some connection with plant phylogeny; more flavonoids might be contained in relatively primitive bryophytes. Meanwhile, the effects of ecological factors on total flavonoid contents of bryophytes exist; light and habitat (especially tree habitat and river habitat might be representative factor.

137Cs concentrations in northern Alaskan Eskimos, 1962-79: effects of ecological, cultural and political factors

International Nuclear Information System (INIS)

Hanson, W.C.

1982-01-01

Concentrations of worldwide fallout 137 Cs were measured in the lichen-caribou-Eskimo food chain of northern Alaska during the period 1962-79. Pronounced inputs of fallout occurred after major nuclear weapons tests in the atmosphere and 137 Cs was transmitted through the food chain to Eskimos with about a 2-yr delay due to environmental parameters. Caribou (Rangifer tarandus) meat sampled during spring harvest contained 4 times the 137 Cs concentration of lichens obtained from their winter range. Calculated caribou meat ingestion rates of Anaktuvuk Pass Eskimos during winter ranged from approximately equal to 1 kg/day in 1964 to 0.16 kg/day in 1977. Several environmental factors affected seasonal patterns and amounts of 137 Cs transferred through the food chain. Maximum 137 Cs concentrations of approximately equal to 20 nCi/kg body weight in Eskimos occurred in 1964 and have now decreased to approximately equal to 0.5 nCi/kg, largely because of cultural and political factors. Radiation doses from 137 Cs body burdens during the study period ranged from 60 mrad/yr in 1962 to approximately equal to 140 mrad/yr during the 1962-64 maxima and decreased to 8 mrad/yr in 1979.

Who governs energy? The challenges facing global energy governance

International Nuclear Information System (INIS)

Florini, Ann; Sovacool, Benjamin K.

2009-01-01

This article conceptualizes the energy problems facing society from a global governance perspective. It argues that a notion of 'global energy governance,' taken to mean international collective action efforts undertaken to manage and distribute energy resources and provide energy services, offers a meaningful and useful framework for assessing energy-related challenges. The article begins by exploring the concepts of governance, global governance, and global energy governance. It then examines some of the existing institutions in place to establish and carry out rules and norms governing global energy problems and describes the range of institutional design options available to policymakers. It briefly traces the role of a selection of these institutions, from inter-governmental organizations to summit processes to multilateral development banks to global action networks, in responding to energy issues, and points out their strengths and weaknesses. The article concludes by analyzing how the various approaches to global governance differ in their applicability to addressing the conundrums of global energy problems.

Crepuscular flight activity of an invasive insect governed by interacting abiotic factors.

Directory of Open Access Journals (Sweden)

Yigen Chen

Full Text Available Seasonal and diurnal flight patterns of the invasive walnut twig beetle, Pityophthorus juglandis, were assessed between 2011 and 2014 in northern California, USA in the context of the effects of ambient temperature, light intensity, wind speed, and barometric pressure. Pityophthorus juglandis generally initiated flight in late January and continued until late November. This seasonal flight could be divided approximately into three phases (emergence: January-March; primary flight: May-July; and secondary flight: September-October. The seasonal flight response to the male-produced aggregation pheromone was consistently female-biased (mean of 58.9% females. Diurnal flight followed a bimodal pattern with a minor peak in mid-morning and a major peak at dusk (76.4% caught between 1800 and 2200 h. The primarily crepuscular flight activity had a Gaussian relationship with ambient temperature and barometric pressure but a negative exponential relationship with increasing light intensity and wind speed. A model selection procedure indicated that the four abiotic factors collectively and interactively governed P. juglandis diurnal flight. For both sexes, flight peaked under the following second-order interactions among the factors when: 1 temperature between was 25 and 30 °C and light intensity was less than 2000 lux; 2 temperature was between 25 and 35 °C and barometric pressure was between 752 and 762 mba (and declined otherwise; 3 barometric pressure was between 755 and 761 mba and light intensity was less than 2000 lux (and declined otherwise; and 4 temperature was ca. 30 °C and wind speed was ca. 2 km/h. Thus, crepuscular flight activity of this insect can be best explained by the coincidence of moderately high temperature, low light intensity, moderate wind speed, and low to moderate barometric pressure. The new knowledge provides physical and temporal guidelines for the application of semiochemical-based control techniques as part of an IPM

Tiered approaches have become a standard means of structuring information in the process of conducting environmental risk assessments. For cases involving the assessment of impacts on wildlife from ionising radiation, the ERICA integrated approach and its supporting software (The ERICA Tool) provides such a structure, splitting the system into two generic screening tiers and a third site-specific tier. The first Tier is very simple, based around Environmental Media Concentration Limits, EMCLs, and requires minimal input from the assessor. The second Tier, although still a screening tier, calculates dose rates and requires more detailed input from the assessor allowing for scrutiny and editing of default parameters in the process. A key element of Tier 2 involves the application of Uncertainty Factors, UFs. Such factors reflect our knowledge concerning probability distribution functions and provide a way of incorporating conservatism into the assessment by considering high percentile values in underlying parameters. Following its launch in 2007, there have been significant developments regarding certain components of the ERICA integrated approach. Most notably, an extended international collation of concentration ratio data has precipitated the need to update parameter values in the Tools databases. In addition, more considered guidance has been developed with regards to filling knowledge gaps in the absence of transfer data. Furthermore, the efficacy of the methods used in assigning probability distribution functions has been questioned leading to an acknowledgement from the developers that the methods were not described in enough detail nor were the justifications for applying the selected approach provided in a convincing way. This has implications for the EMCL values which are derived probabilistically using parameters including concentration ratios. Furthermore, there are implications for UF derivation that relies upon a robust consideration of underlying

Governability in Contemporary Mexico

Directory of Open Access Journals (Sweden)

Leonardo Curzio Gutiérrez

1998-04-01

Full Text Available Given the difficulties to establish a concept of governability and the frequent ideological usage of the term, it is much more operative to turn to the principle of governability, in the broad sense, which supports itself on five pillars: the political legitimacy of the government, the governmental efficiency to attend to the demands of society, the existence of shared social project, the agreement with the principle special interest groups, and international viability. The analysis of the structure and relevance of these five points during the long period of political transition that Mexico underwent between 1988 and 1997 shows how it was possible for this country to play off certain factors against each other in order to secure governability and safeguard against the consequences of any resultant imbalances. Between 1998-1993, the government of Salinas de Gotari based itself on the viability of a neoliberal project within an international context, and on this projectís attention to domestic demands as well as on the governmentís pact with elites. Institutional integration and legitimacy made up, then, for a process of discreet liberalization and the lack of democratic electoral commitment, which culminated in the PRI’s 1994 elections victory.The assassination of Colosia, though, and the appearance of the EZLN and the subsequent crisis surrounding the peso’s devaluation that accompanied Ernesto Zedilloís rise to power soon led to the collapse of those pillars of support. Crowning the process of the silenttransition were the elections of 1997, which makes it possible to say that in Mexico today there are now smooth elections, but that reform of the State is still unresolved —a subject that includes the reduction of the president’s competence. Seen in the short term, the most direct threats to Mexico’s governability will come as a result of the lack of attention to those demands of society’s underprivileged and the ill

Multi-actor governance of sustainable biofuels in developing countries: The case of Mozambique

International Nuclear Information System (INIS)

Schut, Marc; Cunha Soares, Núria; Ven, Gerrie van de; Slingerland, Maja

2014-01-01

This paper describes and analyses the multi-actor governance process that made Mozambique the first African nation-state to develop a national policy framework for sustainable biofuels. The paper draws on findings from action research conducted in Mozambique between December 2008 and July 2012. We analyse interactions between the changing governance context, the course of the multi-actor governance process, and the choices in relation to governance framework characteristics and content for four successive stages of governance framework development. This provides the basis for reflection on the competences required for effective multi-actor sustainability governance, and a discussion about the role of the nation-state in sustainability governance of global economies such as biofuels. The governance framework for sustainable biofuels has contributed to a more transparent and secure investment climate for biofuels in Mozambique. Key factors for success were (1) the presence of different types of competences during the various stages of the governance framework development, (2) closing the gap between ‘licences to sell’ and ‘licences to produce’ across different governance levels, and (3) balancing between the short- and long-term objectives for biofuel production in Mozambique and requirements of global biofuel markets. Developing-country nation-states can provide an essential contribution to these success-factors for global governance of sustainable biofuels. - Highlights: • Mozambique is the first African country that developed a national governance framework for sustainable biofuels. • Independence, representation, expertise and operational capacity are essential competences in multi-actor sustainability governance. • Developing country's nation-states play an essential role in harmonizing short- and long-term objectives across different governance levels. • Synergies between licences to sell and licences to produce biofuels sustainably should

Hospitals in Taiwan are facing major changes and innovation is increasingly becoming a critical factor for remaining competitive. One determinant that can have a significant impact on innovation is hospital governance. However, there is limited prior research on the relationship between hospital governance and innovation. The purpose of this study is to propose a conceptual framework to hypothesize the relationship between governance mechanisms and innovation and to empirically test the hypotheses in hospital organizations. We examine the relationship between governance mechanisms and innovation using data on 102 hospitals in Taiwan from the Taiwan Joint Commission on Hospital Accreditation and Quality Improvement. We model governance mechanisms using board structure, information transparency and strategic decision-making processes. For our modeling and data analysis we use measurement and structural models. We find that in hospital governance, information transparency and strategic decision making did impact innovation. However, governance structure did not. To facilitate innovation, hospital boards can increase information transparency and improve the decision-making process when considering strategic investments in innovative initiatives. To remain competitive, hospital boards need to develop and monitor indices that measure hospital innovation to ensure ongoing progress. Copyright © 2017 John Wiley & Sons, Ltd.

Full Text Available The purpose of this research is to examine factors that may affect fraud on financial statements that could encourage the emergence of corruption by management. This research uses banks as an industry sample because the banking industry is highly regulated and should report their financial statement to a central bank. Meanwhile, banks still frequently have fraudulent financial statements. Good corporate governance mechanisms indicated that banks have the capability to detect fraud in financial statements. This research focuses on testing factors that may affect the financial statements fraud which lead to the corruption of management. The data used in this research is financial statement data. Corporate governance mechanisms tested in this study are the number of commissioners, percentage of independent directors, number of commissioners meeting, percentage of largest share ownership, managerial ownership, long tenure of commissioners, and type of auditor. This research found that the number of commissioners and managerial ownership affects management's fraud, while the number of independent directors, the number of commissioners meeting, a long tenure managing director, large share ownership, and the type of auditor has no effect on fraud.

Statins, 3-hydroxy-3-methyl-glutaryl-coenzyme A reductase inhibitors, have proven efficacy in both lowering low-density-lipoprotein levels and preventing major coronary events, making them one of the most commonly prescribed drugs in the United States. Statins exhibit a class-wide side effect of muscle toxicity and weakness, which has led regulators to impose both dosage limitations and a recall. This review focuses on the best-characterized genetic factors associated with increased statin muscle concentrations, including the genes encoding cytochrome P450 enzymes (CYP2D6, CYP3A4, and CYP3A5), a mitochondrial enzyme (GATM), an influx transporter (SLCO1B1), and efflux transporters (ABCB1 and ABCG2). A systematic literature review was conducted to identify relevant research evaluating the significance of genetic variants predictive of altered statin concentrations and subsequent statin-related myopathy. Studies eligible for inclusion must have incorporated genotype information and must have associated it with some measure of myopathy, either creatine kinase levels or self-reported muscle aches and pains. After an initial review, focus was placed on seven genes that were adequately characterized to provide a substantive review: CYP2D6, CYP3A4, CYP3A5, GATM, SLCO1B1, ABCB1, and ABCG2. All statins were included in this review. Among the genetic factors evaluated, statin-related myopathy appears to be most strongly associated with variants in SLCO1B1. PMID:24810685

Full Text Available In recent years, research, society and industry recognize the need to transform the agri-food system towards sustainability. Within this process, sustainability experiments play a crucial role in transforming the structure, culture and practices. In literature, much attention is given to new business models, even if the transformation of conventional firms toward sustainability may offer opportunities to accelerate the transformation. Further acceleration could be achieved through collaboration of multiple actors across the agri-food system, but this calls for a systems approach. Therefore, we developed and applied a new sustainability experiment systems approach (SESA consisting of an analytical framework that allows a reflective evaluation and cross-case analysis of multi-actor governance networks based on business and learning evaluation criteria. We performed a cross-case analysis of four agri-food sustainability experiments in Flanders to test and validate SESA. Hereby, the key factors of the success of collaboration and its performance were identified at the beginning of a sustainability experiment. Some of the key factors identified were risk sharing and the drivers to participate. We are convinced that these results may be used as an analytical tool for researchers, a tool to support and design new initiatives for policymakers, and a reflective tool for participating actors.

Silicon concentrator cells in a two-stage photovoltaic system with a concentration factor of 300x

Energy Technology Data Exchange (ETDEWEB)

Mohr, A.

2005-06-15

In this work a rear contacted silicon concentrator cell was developed for an application in a two stage concentrator photovoltaic system. This system was developed at Fraunhofer ISE some years ago. The innovation of this one-axis tracked system is that it enables a high geometrical concentration of 300x in combination with a high optical efficiency (around 78%) and a large acceptance angle of {+-}23.5 all year through. For this, the system uses a parabolic mirror (40.4x) and a three dimensional second stage consisting of compound parabolic concentrators (CPCs, 7.7x). For the concentrator concept and particularly for an easy cell integration, the rear line contacted concentrator (RLCC) cells with a maximum efficiency of 25% were developed and a hybrid mounting concept for the RLCC cells is presented. The optical performance of different CPC materials was tested and analysed in this work. Finally, small modules consisting of six series interconnected RLCC cells and six CPCs were integrated into the concentrator system and tested outdoor. A system efficiency of 16.2% was reached at around 800 W/m2 direct irradiance under realistic outdoor conditions. (orig.)

Full Text Available We examine the relationship between firm valuation and governance mechanisms, firm characteristics, and institutional factors of the American Depository Receipts (ADRs domiciled in the Greater China region. We find that China ADRs have the highest market-to-book value ratio followed by Hong Kong and Taiwan ADRs. It appears that Chinese firms with the poorest external governance environment stand to benefit the most from cross listing under the ADR programs. Listing in the U.S. that requires more stringent regulations and disclosure rules may strengthen the firms’ governance practices and thereby enhance their firm value. Among the internal governance mechanisms, institutional ownership and insider ownership are important for firm value.

Full Text Available Corporate governance is one of the most vital issues in this compound environment at present, which is indicated by the fact that the success or failure of firms strongly depends on performance of the control that board of directors and executive board, take on corporations’ activities. This issue has attracted a variety of researches worldwide, and become a popular buzz lately, however there is still limited researches on this topic in Vietnam. In this paper, we focus on manufacturing sector, one of the most important industries in Vietnam economy, which account for 41.2% of total GDP in 2012. By using stakeholder theory and Kitamura’s paper as a corner stone, a model using OLS regression and log functional form for production function, showing the relationship between some external factors and internal factors including corporate governance is built. From the result of the research, it has been found out that internal factors (corporate governance significantly affect the firm’s performance, whereas external factors (market share do not really show any influence. In term of production function, this manufacturing sector still benefits from an increase of capital but not that of labor.

With the emergence of global health comes governance challenges which are equally global in nature. This article identifies some of the initial limitations in analyses of global health governance (GHG) before discussing the focus of this special supplement: the framing of global health issues and the manner in which this impacts upon GHG. Whilst not denying the importance of material factors (such as resources and institutional competencies), the article identifies how issues can be framed in different ways, thereby creating particular pathways of response which in turn affect the potential for and nature of GHG. It also identifies and discusses the key frames operating in global health: evidence-based medicine, human rights, security, economics and development.

Fe, Cu, Zn, Mn, Co, and Mg were analysed in the ovary of Carcinus maenas and Cancer irroratus during ovogenesis. In both ovaries, the relatives rates, expressed as parts per millions as a ratio of wet and dry weight, are the following: Mg>Zn>Fe>Cu>Mn>Co, while in the hemolymph of Cancer irroratus these relative rates are the following: Mg>Cu>Zn>Fe>Mn>Co. Compared to concentrations of these metals in sea water, Mg expected, all metals in the ovary of Cancer irroratus have a concentration factor upper than 1. Compared to the concentration of metals in the hemolymph is, for Fe, Mn, and Co, the concentration factor upper than 1, and for Cu, Zn and Mg, the concentration factor lower than 1. A study of correlations was done between the concentrations of metals considered in pairs, and between the concentrations of metals and the parameters: water content and gonad index [fr

Influences of Government Championship on the Technology Innovation Process at the Project-level

Science.gov (United States)

Yue, Xin

Government support is a popular instrument to foster technology innovation. It can take various forms such as financial aid, tax credits, and technological assistance. Along with the firm characteristics, strategic behavior of the project team, characteristics of the technology and the market, and the regulatory environment, government support influences firms' research and development (R&D) motivations, decision making process, and hence technology development performance. How government support influences the performance in different industries is an important policy and research question. There are many studies on the effectiveness and impacts of government support, mostly at program-level or industry-level. Government Championship is a form of government support distinct from direct financial or technological assistance. Championship includes expressing confidence in the innovation, encouraging others to support the innovation, and persisting under adversity. Championship has been studied as a critical inside factor for innovation success, particularly at project-level. Usually a champion emerged within the organization responsible for the innovation project. However, with the intention to encourage technology development, governments can also play a championship role. Government championship, besides government financial and technological assistance (hereafter "government F&T"), could be one major category of government support to facilitate high-technology innovation. However, there are few studies focusing on the effectiveness of government championship, and how it influences the innovation process. This thesis addresses this question through two studies on high-technology development projects. The first study has tested the effectiveness of government championship on the performance of 431 government sponsored technology innovation projects. Government championship and government F&T, as well as project team strategic behavior, are hypothesized to influence

Synthetic biology regulation and governance: Lessons from TAPIC for the United States, European Union, and Singapore.

Science.gov (United States)

Trump, Benjamin D

2017-11-01

Synthetic biology is an emerging technology with potential benefits to various fields, yet also contains potential risks to human and environmental health. The field remains in an emerging state with limited quantitative guidance and a small but growing population of international researchers that conduct work within this field. Given the uncertain nature of this technology, an adaptive and anticipatory governance framework may be necessary to balance the potential benefits that may accrue from the technology's continued research alongside a desire to reduce or eliminate potential risks that may arise. However, such developments must account for the unique political and institutional factors that form a government's risk culture - something that can facilitate or impede the development of adaptive synthetic biology governance moving forward. The TAPIC framework helps illustrate those factors that are essential to develop good governance for emerging technologies like synthetic biology. Specifically, an application of TAPIC to synthetic biology governance indicates that the factors of accountability, participation, and integrity must be bolstered to improve technology governance in governments like with the United States, European Union, and Singapore.

Combining resting-state functional magnetic resonance imaging (fMRI) connectivity and behavioral analysis during sedation, we factored out general effects of the anesthetic drug propofol and a specific index of conscious report, participants' level of responsiveness. The factorial analysis shows that increasing concentration of propofol in blood specifically decreases the connectivity strength of fronto-parietal cortical loops. In contrast, loss of responsiveness is indexed by a functional disconnection between the thalamus and the frontal cortex, balanced by an increase in connectivity strength of the thalamus to the occipital and temporal regions of the cortex.

stated preference to embed Dutch efforts within in broader European policy frameworks. The findings broaden our insights into factors shaping government support for promising fields of science and technology, opportunities for multi-level governance of their effects, and the extent to which convergence in national approaches is a realistic possibility. Given the greater complexity of emerging fields of science and technology, how governments organize themselves to promote research and development---while also protecting public health and the environment---is an increasingly important question.
