Orchestrating Grid Services using BPEL and Globus Toolkit 4

Grid services exploit an emerging distributed computing technology that offers possibilities for distributed resource sharing and collaboration. The standards for WSRF (Web Service Resource Framework) have allowed grid services to converge more closely on web services. Composing web services has attracted significant effort and commercial interest. This has resulted in BPEL (Business Process Execution Logic) as a standard way of orchestrating web services. Because of the similarities with web services, there is a natural question of whether grid services can be orchestrated in like manner. It is explained how CRESS (Chisel Representation Employing Systematic Specification) has been extended to describe grid service composition. It will be seen how BPEL has been adapted for this purpose, using ActiveBPEL as the orchestration engine and Globus Toolkit 4 as the grid service container. The problems arising with orchestrating grid services are discussed, along with possible workarounds.
Exchange Structures in Transition: Lending and Trade Relations in Chinese Business Groups

The networks of interfirm relations that developed in business groups during economic transition are central to China's reform and are becoming an important part of the country's emergent economic structure. Using a recent and original data set that includes direct observations of economic choices made by firms, the process by which these interfirm lending and trade ties emerged and evolved in the early stages of reform is explored. Initially, information from sources external to the network dominated the formation and direction of exchange relations. Firms turned to their prior connections, took advantage of market position, and drew on bureaucratic power to develop alliances. Over time, internal influences gained importance, and managers increasingly drew on internal nontrade relations and other indicators inside the business group to identify lending and trade partners. The results demonstrate the central but changing role that social relations and environmental cues played in the creation of economic structure during China's transition. This study also contributes to an understanding of the processes of organizational adaptation to a major economic transition and interfirm alliance formation more generally. The findings reveal that firms select exchange partners of known reputation and solicit relations that reduce uncertainty, even when there is a cost involved.
Relative culture: A study on contexting and extraversion among American and Polish expatriates

Purpose – The purpose of this study was to advance the understanding of the effect of extraversion on an expatriate's level of contexting (adopting a higher or lower level of context) while abroad. Particularly, this study focused on Polish expatriates in the US and American expatriates in Poland. Design/methodology/approach – The participants were 30 American expatriates living in Poland and 41 Polish expatriates living in the USA. Findings – The results from the regression analysis suggest that extraversion has a different effect on contexting among Polish expatriates than American expatriates, the higher the level of extraversion, the more context dependent the American expatriates were. Moreover, Polish and American expatriates differ in terms of contexting related to the universalism and the particularism dimensions of the seven cultural dimensions from Hampden-Turner and Trompenaars. Originality/value – This advanced understanding led the researchers to give practical implications on the training of expatriates for their abroad assignments.
Inbound, outbound or peripheral: the impact of discourses of ‘organisational’ professionalism on becoming a teacher in English further education

This article explores constructions of teacher identities at a time of significant changes to public service professionalism. The article draws on different discourses of professionalism, contrasting ‘organisational’ and ‘occupational’ professionalism, with discourses of ‘personal’ and ‘critical’ professionalism, to explore changing meanings and enactments of teacher professionalism in the 2000s. Narratives of three novice teachers, followed over eight years, are used to consider the impact of dominant discourses of ‘organisational’ professionalism in English further education, resulting in inbound, outbound and peripheral trajectories. In response, the article considers how practitioners might engage critically with current changes, arguing that it is necessary to work with what matters to teachers, such as their relations with students, teaching and learning and subject specialism. Such work might create, at least temporarily and locally, spaces in which more favourable conditions towards socially just and enabling educational practices can be worked towards.
Empleo del Análisis de Redes Sociales para el estudio de la estructura de la relación entre definiciones del concepto estrategia elaboradas entre los años 1962 y 2003

The present work was carried out to determine the structure of relations among the definition of the concept “strategy” that have been elaborated by authors from its origin in the decade of the sixties during the twentieth century. For its execution, thirty-eight definitions were taken as a sample. Each of them was deconstructed to identify the key terms used by the authors. Once it was accomplished, a filiations’s matrix was elaborated using the authors as the observation unit and the definition’s key terms as variables. Then (1) was assigned to the presence of the term in the definition and zero to the absence of it. Finally, the structure of the relations among key terms was obtained through the program Net Draw. The Kappa Cohen test was applied to determine the coefficient of concordance between each pair of authors who dealt with the definition of the concept of Strategy, then a incidence matrix was built assuming that there is 1 if only there is a coefficient of concordance (K>0.40) and there is no relation (0) if the opposite
Elevated serum chemerin levels are associated with the presence of coronary artery disease in patients with metabolic syndrome.

OBJECTIVE Patients with metabolic syndrome (MetS) are at a high risk for developing atherosclerosis and cardiovascular disease. Serum levels of chemerin have been found elevated in subjects with MetS and are associated with several cardiovascular factors. This study was undertaken to determine whether serum chemerin levels are associated with coronary artery disease (CAD) in patients with MetS. METHODS A total of 112 patients with MetS (66 patients with CAD and 46 without CAD) and 52 healthy subjects who underwent coronary angiography for the evaluation of CAD were enrolled in this study. Serum levels of chemerin were measured by enzyme-linked immunosorbent assay. RESULTS Serum chemerin levels were significantly elevated in MetS patients with CAD compared to in those without CAD and healthy subjects. MetS patients without CAD also had higher serum chemerin levels compared with healthy subjects. Multivariate logistic regression analysis revealed that serum chemerin levels were significantly associated with the presence of CAD in patients with MetS. Simple linear regression analysis showed that the serum levels of chemerin were positively correlated with body mass index (BMI), systolic blood pressure (SBP), serum triglycerides and C-reactive protein (CRP) in patients with MetS. Only BMI and CRP remained significantly associated with serum chemerin after multiple stepwise regression analysis. CONCLUSION Elevated serum chemerin levels could be considered as an independent predictive marker of the presence of CAD in patients with MetS.
EEG signal classification in non-linear framework with filtered training data

Electroencephalographic (EEG) signals are produced in brain due to firing of the neurons. Any anomaly found in the EEG indicates abnormality associated with brain functioning. The efficacy of automated analysis of EEG depends on features chosen to represent the time series, classifier used and quality of training data. In this work, we present automated analysis of EEG time series acquired from two different groups. Non-linear features have been used here to capture the characteristics of EEG in each case since it portrays the non-linear dependencies of different parameters associated with EEG. In the first case, we present the classification between alcoholics and controls. In the second case, we present classification between epileptic and controls. In the classification, we have addressed the issue of quality of training data. In the proposed scheme prior to classification, we filter the training data. This approach led to minimum 10% improvement in the classification accuracy.
Principal Milk Components in Buffalo, Holstein Cross, Indigenous Cattle and Red Chittagong Cattle from Bangladesh

The aim of the present study was to get a total physical and chemical characterization and comparison of the principal components in Bangladeshi buffalo (B), Holstein cross (HX), Indigenous cattle (IC) and Red Chittagong Cattle (RCC) milk. Protein and casein (CN) composition and type, casein micellar size (CMS), naturally occurring peptides, free amino acids, fat, milk fat globule size (MFGS), fatty acid composition, carbohydrates, total and individual minerals were analyzed. These components are related to technological and nutritional properties of milk. Consequently, they are important for the dairy industry and in the animal feeding and breeding strategies. Considerable variation in most of the principal components of milk were observed among the animals. The milk of RCC and IC contained higher protein, CN, β-CN, whey protein, lactose, total mineral and P. They were more or less similar in most of the all other components. The B milk was found higher in CN number, in the content of αs2-, κ-CN and α-lactalbumin, free amino acids, unsaturated fatty acids, Ca and Ca:P. The B milk was also lower in β-lactoglobulin content and had the largest CMS and MFGS. Proportion of CN to whey protein was lower in HX milk and this milk was found higher in β-lactoglobulin and naturally occuring peptides. Considering the results obtained including the ratio of αs1-, αs2-, β- and κ-CN, B and RCC milk showed best data both from nutritional and technological aspects.
A Partial Solution to the Base Rate Problem of the k Statistic

To the Editor. — Recently there has been a dispute among experts concerning the measurement of diagnostic agreement1-3and the use of the k statistic.4We share the view of Uebersax5that the real solution to this problem will require new paradigms for assessing interjudge agreement, and in particular that the more expensive multiple-judge designs or criteriondiagnosis designs are desirable. However, we do not accept that developing correction formulas to equate k values obtained from samples with different base rates is pointless.2,5Under the conventional models for psychiatric diagnosis that underlie the calculation of k, it is possible to adjust k so as to incorporate base rate differences. This adjustment does not address the more complex issues raised,1,2,5but may go some way toward reconciling divergent views2,3about k. Following Spitznagel and Helzer,1we define the sensitivity of a judge as the probability of
Temporal Patterns in Online Food Innovation

Since innovation plays an important role in the context of food, as evident in how successful chefs, restaurants or cuisines in general evolve over time, we were interested in exploring this dimension from a more virtual perspective. In particular, the paper presents results of a study that was conducted in the context of a large-scale German online food community forum to explore another important dimension of online food recipe production, namely known as online food innovation. The study shows interesting findings and temporal patterns in terms of how online food recipe innovation takes place.
NS2B-3 proteinase-mediated processing in the yellow fever virus structural region: in vitro and in vivo studies

Several of the cleavages required to generate the mature nonstructural proteins from the flaviviral polyprotein are known to be mediated by a complex consisting of NS2B and a serine proteinase domain located in the N-terminal one-third of NS3. These cleavages typically occur after two basic residues followed by a short side chain residue. Cleavage at a similar dibasic site in the structural region is believed to produce the C terminus of the virion capsid protein. To study this cleavage, we developed a cell-free trans cleavage assay for yellow fever virus (YF)-specific proteolytic activity by using a substrate spanning the C protein dibasic site. Cleavage at the predicted site was observed when the substrate was incubated with detergent-solubilized lysates from YF-infected BHK cells. NS2B and the NS3 proteinase domain were the only YF-specific proteins required for this cleavage. Cell fractionation studies demonstrated that the YF-specific proteolytic activity was membrane associated and that activity could be detected only after detergent solubilization. Previous cell-free studies led to a hypothesis that processing in the C-prM region involves (i) translation of C followed by translocation and core glycosylation of prM by using an internal signal sequence, (ii) signalase cleavage to produce a membrane-anchored form of the C protein (anchC) and the N terminus of prM, and (iii) NS2B-3-mediated cleavage at the anchC dibasic site to produce the C terminus of the virion C protein. However, the results of in vivo transient-expression studies do not support this temporal cleavage order. Rather, expression of a YF polyprotein extending from C through the N-terminal one-third of NS3 revealed that C-prM processing, but not translocation, was dependent on an active NS2B-3 proteinase. This suggests that signalase-mediated cleavage in the lumen of the endoplasmic reticulum may be dependent on prior cleavage at the anchC dibasic site. Possible pathways for processing in the C-prM region are outlined and discussed.
Host Galaxies of low z Radio-loud Quasars: A search of HST archives. 1

We searched the HST archives for unpublished WFPC2 images of low redshift (z < 0.5) radio loud quasars (RLQ). This led to the identification of 11 objects. We present here the results of the analysis of these images from which we derive the properties of their host galaxies. All objects are clearly resolved and their surrounding nebulosity is consistent with an elliptical galaxy model. These new data, together with previous published HST observations, form a sample of 34 sources which significantly expands all previous studies of low redshift RLQ based on HST data. For this full sample we derive the average absolute magnitude of the host galaxies < MR >= −24.01±0.48, and the effective radius < Re >= 10.5±3.7 kpc. No significant correlation is found between the nucleus and the host galaxy luminosity. Using the relationship between black hole mass (MBH) and bulge luminosity we investigate the relation between MBH and total radio power for RLQ and compare with other classes of radio sources. The overall distribution of AGN in the plane MBH-Pradio exhibits a trend for increasing MBH with increasing Pradio but with a substantial spread. RLQ occupy the region of most powerful sources and most massive BH. The quasars appear to emit over a wide range of power with respect to their Eddington luminosity as deduced by the estimated MBH . Subject headings: Galaxies: active – galaxies: evolution – Quasars: general Based on observations with the NASA/ESA Hubble Space Telescope, obtained at the Space Telescope Science Institute, which is operated by the Association of Universities for Research in Astronomy, Inc., under NASA contract NAS 5-26555
3P-Bridge Cascaded PWM Rectifier Suitable for HV Side of PET

A novel topology of three-phase-bridge (3P-bridge) cascaded PWM rectifier was proposed and analyzed in this paper. The two-level cascaded 3P-bridge topology is composed of three basic cells and the basic cell is a three-phase voltage source PWM converter; the line voltages in AC side of the converter are produced through cascaded way. The analysis results showed that the proposed converter in this paper could be used for three-phase system of high-voltage and high-power directly, such as power electronic transformer (PET); its control method is simple and flexible. The simulation results demonstrated the correctness of the proposed converter and verified the theoretical predictions, with the One-cycle control (OCC) under vector operation mode.
Antiphonal exchanges in African elephants (Loxodonta africana): collective response to a shared stimulus, social facilitation, or true communicative event?

Female African elephants are thought to exchange 'rumble' vocalizations, but such temporally associated calls may not constitute communicative events. Affiliated females are more likely to engage in antiphonal calling, but affiliation is defined according to time spent in proximity. Affiliated partners may vocalize in sequence simply because their proximity causes them to collectively respond to shared external stimuli or due to a social facilitation effect. We used bi-variate and partial correlation analyses to test for the independent effects of the strength of the social relationship and distance between vocal partners on the likelihood of a vocal response. Female African elephants at Disney's Animal Kingdom were video-taped and outfitted with audio-recording collars that allowed for the individual identification of low-frequency rumbles. Affiliation had a strong influence on response likelihood, even after controlling for the effects of the distance between vocalizing partners. Further, the distance between vocalizing partners did not correlate with response likelihood, and factoring out the effects of affiliation did not significantly alter this result. These results suggest that rumble exchanges are communicative events that reflect social bonds, not simply artifacts of increased proximity and, therefore, provide support for functional hypotheses concerning rumble exchanges in wild African elephants.
Inbreeding in artificial selection programmes.

In a population under artificial selection, the effective population size may be less than the actual number of parents selected because there will be variation between families in the character under selection and consequently in the probability of selection. Expressions are developed for the magnitude of the effect, which will be greater the more intense the selection and the higher the heritability of the selected character. The inbreeding due to outstanding individuals may rise for several generations after their use.
When Do Close Elections Matter for Higher Turnout? Gauging the Impact of the Interaction Between Electoral Competitiveness and District Magnitude

Abstract A conventional rational choice perspective assumes a positive relationship between close elections and higher turnout because of the increased probability that few votes might actually matter for the election outcome. However, this hypothesis should only hold in electoral districts where one or few candidates are elected. In contrast, close elections should have less of an impact in districts where many members are elected because these districts are characterized by a proportional translation of votes into seats. Testing the foregoing logic, this article evaluates the interactive influence between the closeness of an election and the district magnitude on turnout. The results of the multivariate regression analysis, which includes data for over 600 elections across the globe, support the idea that close elections boost electoral participation in districts with one or few elected members, but not in districts with many elected representatives.
Local activation of coagulation and inhibition of fibrinolysis in the lung during ventilator associated pneumonia

Background: Fibrin deposition is a hallmark of pneumonia. To determine the kinetics of alterations in local coagulation and fibrinolysis in relation to ventilator associated pneumonia (VAP), a single centre prospective study of serial changes in pulmonary and systemic thrombin generation and fibrinolytic activity was conducted in patients at risk for VAP. Methods: Non-directed bronchial lavage (NBL) was performed on alternate days in patients expected to require mechanical ventilation for more than 5 days. A total of 28 patients were studied, nine of whom developed VAP. Results: In patients who developed VAP a significant increase in thrombin generation was observed in the airways, as reflected by a rise in the levels of thrombin-antithrombin complexes in NBL fluid accompanied by increases in soluble tissue factor and factor VIIa concentrations. The diagnosis of VAP was preceded by a decrease in fibrinolytic activity in NBL fluid. Indeed, before VAP was diagnosed clinically, plasminogen activator activity levels in NBL fluid gradually declined, which appeared to be caused by a sharp increase in NBL fluid levels of plasminogen activator inhibitor 1. Conclusion: VAP is characterised by a shift in the local haemostatic balance to the procoagulant side, which precedes the clinical diagnosis of VAP.
Influence of orientation of exiting wire of search coil annulus on torsion after saccades.

PURPOSE Research has shown that the orientation of the exiting wire from a scleral search coil (nasal in the original coil, inferior in the modified coil) influences the pattern of torsion associated with blinks, presumably due to the upper eyelid touching the wire. The present study was conducted to investigate whether coil wire orientation also influences the pattern of torsion during fixation after saccades and consequently influences parameters that determine Listing's plane and Donders' law. METHODS Three-axis, binocular eye rotations were recorded in three healthy human subjects looking at an array of small light-emitting diodes at a 124-cm distance. They made predominantly vertical or predominantly horizontal saccades (5-40 degrees, amplitude) at three (0 +/- 20 degrees) azimuths, or elevations. RESULTS With the modified coil, the horizontal component of Listing's primary position was similar for horizontal (mean temporal deviation, 2.9 degrees) and vertical (3.3 degrees) saccades. With the original coil, the horizontal component of primary position was more temporal after horizontal (12.3 degrees) than vertical (6.1 degrees) saccades. The vertical component of primary position was similar with both coils after horizontal and vertical saccades. Listing's plane was thinner with the modified coil after horizontal (standard deviation of torsion from a plane of 0.71 degrees vs. 1.31 degrees) and vertical (0.84 degrees vs.1.67 degrees) saccades. The standard deviation of torsion at a given eye position (Donders' law) was smaller with the modified coil. CONCLUSIONS Measures of torsion after horizontal or vertical saccades depend on whether the coil wire exits nasally or inferiorly and, with the original coil, whether the saccades are horizontal or vertical. Lid contact may account for these potential artifacts. They must be appreciated in the interpretation of three-dimensional search coil recordings, using the scleral annulus.
