Evaluation of accordance of magnetic resonance volumetric and flow measurements in determining ventricular stroke volume in cardiac patients

Background: Cardiovascular magnetic resonance imaging (CMR) has become an established noninvasive method for evaluating ventricular function utilizing three-dimensional volumetry. Postprocessing of volumetric measurements is still tedious and time consuming. Stroke volumes obtained by flow quantification across the aortic root or pulmonary trunk could be utilized to increase both speed of workflow and accuracy. Purpose: To assess accuracy of stroke volume quantification using MR volumetric imaging compared to flow quantification in patients with various cardiac diseases. Strategies for the augmentation of accuracy in clinical routine were deduced. Material and Methods: 78 patients with various cardiac diseases—excluding intra- or extracardiac shunts, regurgitant valvular defects, or heart rhythm disturbance—underwent cardiac function analysis with flow measurements across the aortic root and cine imaging of the left ventricle. Forty-six patients additionally underwent flow measurements in the pulmonary trunk and cine imaging of the right ventricle. Results: Left ventricular stroke volume (LVSV) and stroke volume of the aortic root (SVAo) correlated with r=0.97, and Bland-Altman analysis showed a mean difference of 0.11 ml and a standard error of estimation (SEE) of 4.31 ml. Ninety-two percent of the data were within the 95% limits of agreement. Right ventricular stroke volume (RVSV) and stroke volume of the pulmonary trunk (SVP) correlated with a factor of r=0.86, and mean difference in the Bland-Altman analysis was fixed at –2.62 ml (SEE 8.47 ml). For RVSV and SVP, we calculated r=0.82, and Bland-Altman analysis revealed a mean difference of 1.27 ml (SEE 9.89 ml). LVSV and RVSV correlated closely, with r=0.91 and a mean difference of 2.79 ml (SEE 7.17 ml). SVAo and SVP correlated with r=0.95 and a mean difference of 0.50 ml (SEE 5.56 ml). Conclusion: Flow quantification can be used as a guidance tool, providing accurate and reproducible stroke volumes of both ventricles. Combining both offers a highly accurate tool to gauge ventricular function in a routine clinical setting, increasing workflow speed.
Factors Influencing International Students’ Choice Towards Universities in Malaysia

This paper is aimed to determine factors influencing international postgraduate students in choosing university in Malaysia. Factors such as programs offered, fees, promotion, facilities, prominence, environment, convenience, and scholarship were utilized. A total of 135 international postgraduate students were involved in this study through a direct survey. The percentage technique to extract the information of respondents’ demography was used. Then, the analytic hierarchy process was employed to evaluate the level of importance of each factor. The study found that “programs offered” is the number one factor which influences overall international students’ choice to opt for a postgraduate study in Malaysia universities. There were some differences between students from Asian and Western countries in ranking the importance of those factors. Overall categories of respondents selected “tuition prices”, “facilities”, and the “academic staff prominence” as the preceding factors to follow the “programs offered” factor in a sequential level of importance. In general, the result reflects the awareness of prospective students towards the expected standard of education required from the higher education industry.
Helicobacter pylori, gastrin and cyclooxygenase-2 in lung cancer.

INTRODUCTION Tumors arising in the lungs are in over 90% bronchogenic carcinomas that have been attributed predominantly to tobacco smoking, asbestos or air pollution but little is known about endogenous factors that could facilitate their development and invasiveness. The lungs originate embryologically from the same endoderm cells which form the epithelia lining the digestive tract, where gastrin is the major proliferative stimulus. AIMS Since lung cancer patients were recruited mostly among smokers, who also have been found to exhibit significantly higher infection rate of Helicobacter pylori (HP) infection than non-smokers and, as since the HP-infected subjects show enhanced plasma levels of gastrin, we decided 1) to compare the seroprevalence of HP and the expression of its cytotoxin, CagA, in lung cancer patients with those in the age- and gender-matched controls without cancer: 2) to determine the gene expression for gastrin and its receptors (CCKB-R) in lung cancer, 3) to assess the gastrin levels in plasma bronchial lavage and in tumor tissue and 4) to examine the expression of cyclooxygenase (COX)-1 and COX-2 in cancer tissue resection margin and intact bronchial mucosa. MATERIAL AND METHODS The trial material included 50 patients with lung carcinoma and 100 age- and gender-matched controls. Anti-HP and anti-CagA IgG seroprevalence was estimated by specific antisera using ELISA tests. Gene expression of gastrin, CCKB-R, COX-1 and COX-2 was examined using RT-PCR, while gastrin was measured by specific RIA. RESULTS The seroprevalence of HP, especially that expressing CagA, is significantly higher in lung cancers than in healthy controls. Both gastrin and CCKB-R mRNA were detected in the cancer tissue and at the resection margin and similarly COX-2 mRNA was expressed in most cancers and resection margin but not in bronchial mucosa where only COX-1 was found. The lung cancer tissue and resection margin contained many folds larger amounts of immunoreactive gastrin than intact bronchial mucosa.
The impact of internet crime on development

Purpose – The global wave of information and communication technologies (ICT) development has become a strong driving force in almost every aspect of development. This paper aims to explore the impact of internet crime on individuals, organisations, businesses and government agencies in both developed and developing countries with special reference to developing countries.Design/methodology/approach – The analysis in this paper is based on extensive review of published research works, which provide theoretical and empirical evidence on the effects and impact of the internet on development.Findings – The paper generally concludes that the internet is overwhelmingly a powerful tool for development. Paradoxically, the internet is a “double‐edged sword”, providing many opportunities for individuals and organisations to develop but at the same time, has brought with it new opportunities to commit crime. The paper argues that the internet presents new challenges to law enforcement in both developed and developi.
What ethics for case managers? Literature review and discussion

Background: Little is known about case managers’ ethical issues and professional values. Objectives: This article presents an overview of ethical issues in case managers’ current practice. Findings are examined in the light of nursing ethics, social work ethics and principle-based biomedical ethics. Research design: A systematic literature review was performed to identify and analyse empirical studies concerning ethical issues in case management programmes. It was completed by systematic content analysis of case managers’ national codes of ethics. Findings: Only nine empirical studies were identified, eight of them from North America. The main dilemmas were how to balance system goals against the client’s interest and client protection against autonomy. Professional codes of ethics shared important similarities, but offered different responses to these two dilemmas. Discussion: We discuss the respective roles of professional and organizational ethics. Further lines of research are suggested.
Fed Cattle Spatial Transactions Price Relationships

Abstract Delineation of geographic markets for fed cattle is essential in monitoring price behavior and determining geographic markets. This study uses transactions data from 28 U.S. fed cattle slaughter plants to determine the extent of the geographic market for fed cattle. Results indicate a national market for fed cattle with prices across most plants cointegrated. In addition, price discovery originates predominantly at plants located in Nebraska, and typically one-third of the total price adjustment to spatial integration occurs in one day.
MEASUREMENT OF TECHNICAL EFFICIENCY AND ITS DETERMINANTS IN CROP PRODUCTION IN LAFIA LOCAL GOVERNMENT AREA OF NASARAWA STATE, NIGERIA

This study was designed to measure technical efficiency and identify its determinants in crop production in Lafia Local government Area of Nasarawa State of Nigeria using a stochastic frontier production model. Double stage random sampling technique was used to select 100 crop farmers from which input-output data were collected based on 2005 cropping season. The results revealed that sixty five percent (65%) of the farmers were within the age range of 31-50 years and 67% had farm size ranging from 2-4 hectares. The technical efficiency of crop production range from 32.7% to 89.4% with mean of 69.6%. Farm size and fertilizer were the major inputs that are associated with the variation in crop output. The significant socio economic variables that accounted for the observed variations in technical efficiency among crop farmers were age, gender, marital status, household size, other occupation and land ownership. It is therefore recommended that a land redistribution policy that will increase the farm size of the farmers should be initiated. Fertilizer supply at subsidized rate to farmers in the area should be encouraged. Key words : Technical Efficiency, Determinants, Crop Production.
False Alarms, Tornado Warnings, and Tornado Casualties

Abstract This paper extends prior research on the societal value of tornado warnings to the impact of false alarms. Intuition and theory suggest that false alarms will reduce the response to warnings, yet little evidence of a “false alarm effect” has been unearthed. This paper exploits differences in the false-alarm ratio across the United States to test for a false-alarm effect in a regression model of tornado casualties from 1986 to 2004. A statistically significant and large false-alarm effect is found: tornadoes that occur in an area with a higher false-alarm ratio kill and injure more people, everything else being constant. The effect is consistent across false-alarm ratios defined over different geographies and time intervals. A one-standard-deviation increase in the false-alarm ratio increases expected fatalities by between 12% and 29% and increases expected injuries by between 14% and 32%. The reduction in the national tornado false-alarm ratio over the period reduced fatalities by 4%–11% and inju.
Inter-Local Relations and Divergent Growth: The Detroit and Tokai Auto Regions, 1969 to 1996

ABSTRACT: Drawing on scholarly literature, descriptive data, and 142 face-to-face interviews with non-elected local officials, this article examines the relationship among political-economic context, inter-municipal relations, and spatial outcomes in the primary auto regions of the US (Detroit) and Japan (Tokai) between 1969 and 1996. It maintains that Detroit’s embedded context promoted inter-municipal relations that can best be termed competitive separatism and apathetic avoidance. It then chronicles how such inter-local relations severely exacerbated existing conditions of uneven development in the region over the past 30 years. Conversely, it demonstrates how Tokai’s context encouraged lateral interdependence among communities in its region. It then reveals how inter-local collaboration played a critical role in the relatively balanced metropolitan growth that came to exist there during this time period. It concludes by stating that inter-municipal relations have played a more vital role in metropolitan development than previously has been described in the scholarly literature.
The Winner's Curse and Bidder Competition in Acquisitions: Evidence from Failed Bank Auctions

Auction theory predictions are used to test if winning bidders overpay (the "winner's curse") in FDIC sealed-bid auctions of failed banks. The authors find that winning bids tend to increase as the number of competitors increases, as predicted by theory. Further, bid levels of all bidders increase with increased competition, which is consistent with bidders' failing to adjust for the winner's curse in a common value auction setting. However, additional tests, using only winning bids, only are consistent with both a common value and a private values model, so this result should be interpreted with caution.

Beliefs and Perceived Influence in a Natural Resource Conflict: An Advocacy Coalition Approach to Policy Networks

To what extent do stakeholders in a conflict over natural resources interact with actors of congruent policy core beliefs or with actors who have perceived influence? The response to this question is structured principally by the Advocacy Coalition Framework (ACF) using questionnaire and interview data collected from stakeholders involved in California Marine Protected Area policy. The findings indicate that shared beliefs are the best predictor for policy network relationships, supporting the ACF. Perceived influence, while less important than shared beliefs, is another significant predictor.
Interventions to reduce the stigma of eating disorders: A systematic review and meta‐analysis

Stigma is a problem for individuals with eating disorders (EDs), forming a barrier to disclosure and help-seeking. Interventions to reduce ED stigma may help remove these barriers; however, it is not known which strategies (e.g., explaining etiology to reduce blame, contact with a person with an ED, or educating about ED) are effective in reducing stigma and related outcomes. This review described effectiveness of intervention strategies, and identified gaps in the literature. A search of four databases was performed using the terms (eating disorder* OR bulimi* OR anorexi* OR binge-eating disorder) AND (stigma* OR stereotyp* OR beliefs OR negative attitudes) AND (program OR experiment OR intervention OR education), with additional texts sought through LISTSERVs. Two raters screened papers, extracted data, and assessed quality. Stigma reduction strategies and study characteristics were examined in critical narrative synthesis. Exploratory meta-analysis compared the effects of biological and sociocultural explanations of EDs on attitudinal stigma. Eighteen papers were eligible for narrative synthesis, with four also eligible for inclusion in a meta-analysis. Biological explanations reduced stigma relative to other explanations, including sociocultural explanations in meta-analysis (g = .47, p < .001). Combined education and contact interventions improved stigma relative to control groups or over time. Most studies examined Anorexia Nervosa (AN) stigma and had mostly female, undergraduate participants. Despite apparent effectiveness, research should verify that biological explanations do not cause unintentional harm. Future research should evaluate in vivo contact, directly compare education and contact strategies, and aim to generalize findings across community populations.
THE IMPACT OF BOARD COMPOSITION AND OWNERSHIP ON AUDIT QUALITY: EVIDENCE FROM LARGE UK COMPANIES☆☆☆

Abstract This paper examines the impact of board composition and ownership structure on audit quality in the UK prior to the adoption of the recommendations of the Committee on the Financial Aspects of Corporate Governance ( 5 ). In this study I use audit fees as a proxy for audit quality and seek to investigate whether the proportion of non-executives, the extent of managerial ownership or ownership by large blockholders influences the extent of auditing, and consequently, the audit fee. Utilizing data from a sample of 402 quoted companies I find that the proportion of non-executive directors has a significant positive impact on audit fees. I also find that audit fees are negatively related to the proportion of equity owned by executive directors. I find no evidence that ownership by large blockholders (institutional or otherwise) or CEO/chairman duality has a significant impact on audit fees. Overall, the findings suggest that non-executive directors encourage more intensive audits as a complement to their own monitoring role while the reduction in agency costs expected through significant managerial ownership results in a reduced need for intensive auditing.
Long Forward and Zero-Coupon Rates Can Never Fall

In frictionless markets having no arbitrage, the asymptotic zero-coupon rate never falls. The same is true of the long forward rate. The long par-coupon rate can rise and fall due to forward rate movements at short maturities. This paper relates the three types of interest rate and formalizes and proves the impossibility results for falling asymptotic rates. These results can be tested in a parametric term structure specification that is rich enough to identify a time series of long rates. The results show that it is not possible to specify arbitrarily the long forward or zero-coupon rate process.
The effects of greenfield investment and M&As on domestic investment in developing countries

This article examines the effects of greenfield investment and M&As on domestic investment using panel data for 100 developing countries for the period 2003 to 2011. It is shown that while cross-border M&As do not have a significant effect on domestic investment, greenfield FDI has a large crowding-out effect.
Epidemiology and Clinical Course of Burkholderia cepacia Complex Infections, Particularly Those Caused by Different Burkholderia cenocepacia Strains, among Patients Attending an Italian Cystic Fibrosis Center

ABSTRACT In this study, the epidemiology of Burkholderia cepacia complex (Bcc) recovered from the sputum of 75 patients attending the Genoa Cystic Fibrosis (CF) Center at the Gaslini Children's Hospital (Genoa, Italy) was investigated, and the clinical course of the CF patients infected with the different species and genomovars of Bcc was evaluated. All isolates were analyzed for genomovar status by recA gene polymorphism and subsequently random amplified polymorphic DNA fingerprinting. Burkholderia cenocepacia is the predominant species recovered from the CF patients infected with Bcc at the Genoa CF Center. Of the other eight species comprising the Bcc, only a few isolates belonging to B. cepacia genomovar I, Burkholderia stabilis, and Burkholderia pyrrocinia were found. Of the four recA lineages of B. cenocepacia, most patients were infected by epidemic strains belonging to lineages IIIA and IIID, whereas only a few patients harbored IIIB strains. Patient-to-patient spread of Bcc among CF patients was mostly associated with B. cenocepacia, in particular with strains belonging to recA lineages IIIA and IIID. The mortality of CF patients infected with Bcc at the Genoa CF Center was significantly higher than mortality among CF patients not infected with Bcc. All of the deaths were associated with the presence of B. cenocepacia, except the case of a patient infected with B. cepacia genomovar I. Within B. cenocepacia, infection with epidemic strains belonging to lineages IIIA and IIID was associated with higher rates of mortality than was infection with lineage IIIB strains. No significant differences in lung function, body weight, and mortality rate were observed between patients infected with epidemic strains belonging to either B. cenocepacia IIIA or B. cenocepacia IIID.
Domestic public support for foreign aid: Does it matter?

There is a paradox as First World governments provide decreasing levels of foreign aid despite apparently high levels of domestic public support for foreign aid. This article examines this issue as a case study in government response to public opinion: do governments in democracies pay any real attention to what the public think? The study's methodology is to compare trends in domestic public support for official foreign aid programmes over time in five selected aid donor countries with trends in foreign aid expenditure as a proportion of Gross National Income. There are mixed results: in some cases aid performance increased or decreased in accordance with public opinion; in other cases performance went against public opinion. The reasons can partly be explained by faulty public opinion polling techniques but there also appears to be a substantial problem for public policy making in democracies. Governments are paying little attention to public opinion, at least in so-called elite policy areas such as foreign aid.
International Variations in Tax Disclosures

Abstract We examine the tax disclosures of 161 large IFRS-reporting companies in five countries by studying in detail how they carry out two numerical reconciliations mandated by IAS 12. Using a variety of approaches, we conclude that there are systematic differences in IFRS reporting practice between companies from different countries. However, we also find varied reporting practices within certain industries such as the extractive industry. Based on our observations, we question whether the requirements of the present standard are sufficiently explicit and concise to lead to understandable and comparable tax disclosures. We identify a number of elements of IAS 12 that could be improved.
Planning for Mental Health Care: A Reconsideration of Public Facility Location Theory

This paper suggests that a critical reassessment of the theory of public facility location is long overdue. A comprehensive theory should contain three standard analytical components: location as access; location as externality; and definition of the policy context for public facility planning. Recent empirical research on mental health facility location is used to illustrate the significance of these analytical themes.
Randomized methods for computing low-rank approximations of matrices

Randomized sampling techniques have recently proved capable of efficiently solving many standard problems in linear algebra, and enabling computations at scales far larger than what was previously possible. The new algorithms are designed from the bottom up to perform well in modern computing environments where the expense of communication is the primary constraint. In extreme cases, the algorithms can even be made to work in a streaming environment where the matrix is not stored at all, and each element can be seen only once. The dissertation describes a set of randomized techniques for rapidly constructing a low-rank approximation to a matrix. The algorithms are presented in a modular framework that first computes an approximation to the range of the matrix via randomized sampling. Secondly, the matrix is projected to the approximate range, and a factorization (SVD, QR, LU, etc.) of the resulting low-rank matrix is computed via variations of classical deterministic methods. Theoretical performance bounds are provided. Particular attention is given to very large scale computations where the matrix does not fit in RAM on a single workstation. Algorithms are developed for the case where the original matrix must be stored out-of-core but where the factors of the approximation fit in RAM. Numerical examples are provided that perform Principal Component Analysis of a data set that is so large that less than one hundredth of it can fit in the RAM of a standard laptop computer. Furthermore, the dissertation presents a parallelized randomized scheme for computing a reduced rank Singular Value Decomposition. By parallelizing and distributing both the randomized sampling stage and the processing of the factors in the approximate factorization, the method requires an amount of memory per node which is independent of both dimensions of the input matrix. Numerical experiments are performed on Hadoop clusters of computers in Amazon's Elastic Compute Cloud with up to 64 total cores. Finally, we directly compare the performance and accuracy of the randomized algorithm with the classical Lanczos method on extremely large, sparse matrices and substantiate the claim that randomized methods are superior in this environment.
