Provenance-based trust for grid computing: Position Paper
No full textCurrent evolutions of Internet technology such as Web Services, ebXML, peer-to-peer and Grid computing all point to the development of large-scale open networks of diverse computing systems interacting with one another to perform tasks. Grid systems (and Web Services) are exemplary in this respect and are perhaps some of the first large-scale open computing systems to see widespread use - making them an important testing ground for problems in trust management which are likely to arise. From this perspective, today's grid architectures suffer from limitations, such as lack of a mechanism to trace results and lack of infrastructure to build up trust networks. These are important concerns in open grids, in which "community resources" are owned and managed by multiple stakeholders, and are dynamically organised in virtual organisations. Provenance enables users to trace how a particular result has been arrived at by identifying the individual services and the aggregation of services that produced such a particular output. Against this background, we present a research agenda to design, conceive and implement an industrial-strength open provenance architecture for grid systems. We motivate its use with three complex grid applications, namely aerospace engineering, organ transplant management and bioinformatics. Industrial-strength provenance support includes a scalable and secure architecture, an open proposal for standardising the protocols and data structures, a set of tools for configuring and using the provenance architecture, an open source reference implementation, and a deployment and validation in industrial context. The provision of such facilities will enrich grid capabilities by including new functionalities required for solving complex problems such as provenance data to provide complete audit trails of process execution and third-party analysis and auditing. As a result, we anticipate that a larger uptake of grid technology is likely to occur, since unprecedented possibilities will be offered to users and will give them a competitive edge
ORGANIZATIONAL CULTURE, WORK MOTIVATION, AND WORK EFFECTIVENESS (CASE STUDY ON HOTELS IN TOMOHON AND TONDANO)
No full textThe purpose of this study is to determine the influence of organizational culture and work motivation both partially and simultaneously on the effectiveness of employee work in five hotels in Tomohon And Tondano Cities. For the method used in this study, namely the quantitative method using a sample of 73 employees, and to analyze the data in this study, multiple regression analysis was used. The results found in this study, namely organizational culture and work motivation, both partially and collectively, affect the effectiveness of employee work. Presumably, with the conduct of this study, parties from the five hotels in Tomohon and Tondano Cities can fix the shortcomings that affect the effectiveness of employee work as explained in this study, as well as for subsequent researchers who will conduct research with the same variables and objects as those in this study, not plagiarizing from this study, but rather it only makes this research a reference or reference
Customer Bonding, Customer Satisfaction, and Customer Loyalty (Study on the Customer of “SMEs Martabak Hokky Kawanua†on Tondano)
No full textThis research was conducted on Martabak Hokky SME customers in Tondano city, with the aim of knowing how the level of influence of Customer Bonding to Customer Loyalty, and the influence of Customer Satisfaction to Customer Loyalty, especially in the SMEs  we studied, in addition to that, this research will also look at the joint influence of Customer Bonding and Customer Satisfaction on Customer Loyalty from the SMEs studied. Quantitative method with multiple regression analysis is the method and analysis that is the choice to be used in this study, by taking a sample of 1 10 people. The findings from the multiple analysis test obtained from the study, show that there is a significant effect of Customer Bonding to Customer Loyalty, it can be explained that good Customer Bonding will help increase Loyalitas Customer significantly. The next result also shows a partially significant influence of Customer Satisfaction to Customer Loyalty, so it can be said that if Customer Satisfaction increases, it will also increase Loyalty as Customers significantly as well, The final results of the study show The simultaneous significant influence from Customer Bonding and Customer Satisfaction to Customer Loyalty from SMEs studied in this study, in other words,  the increase in customer loyalty is strongly influenced by the better Customer Bonding and Customer Satisfaction. It can be suggested to the manager of Martabak UKM Hokky Kawanua to be able to pay better attention to how to maintain Customer Bonding and Customer Satisfaction in order to be able to continue to form loyalty from strong customers, so that customers will continue to buy products, and for further research to be able to see and test more deeply about customer loyalty by paying attention to other variables that were not studied in this study
Perceptual estimation of variance in orientation and its dependence on sample size
No full textRecent research has shown that participants are very good at perceptually estimating summary statistics of sets of similar objects (e.g., Ariely, 2001; Chong & Treisman, 2003; 2005). While the research has focused on first-order statistics (e.g., the mean size of a set of discs), it is unlikely that a mental representation of the world includes only a list of mean estimates (or expected values) of various attributes. Therefore, a comprehensive theory of perceptual summary statistics would be incomplete without an investigation of the representation of second-order statistics (i.e., variance). Two experiments were conducted to test participants' ability to discriminate samples that differed in orientation variability. Discrimination thresholds and points of subjective equality for displays of oriented triangles were measured in Experiment 1. The results indicated that participants could discriminate variance without bias and that participant sensitivity (measured via relative thresholds, i.e., Weber fractions) was dependent upon sample size but not baseline variance. Experiment 2 investigated whether participants used a simpler second-order statistic, namely, sample range to discriminate dispersion in orientation. The results of Experiment 2 showed that variance was a much better predictor of performance than sample range. Taken together, the experiments suggest that variance information is part of the visual system's representation of scene variables. However, unlike the estimation of first-order statistics, the estimation of variance depends crucially on sample size.M.S.Includes abstractIncludes bibliographical referencesby Steven A. Cholewia
Pitch structure in Morton Feldman's compositions of 1952:
No full textDuring the year 1952, Morton Feldman composed only a few works, each of which possesses several similarities: each work is scored for the piano, each work was premiered by David Tudor, each is rather modest in proportions, and most importantly, each shares a very similar pitch structure with the others, both
in terms of the particular sonorities that Feldman employs and in terms of how these sonorities are juxtaposed and progress throughout each composition. This essay will show how Feldman, during this early stage of his career, was using a unified pitch language, and furthermore, how one can perceive his pitch structures not only as isolated sonic events, but with clear and integrated relationships to each other. The primary compositions that will be the focus of the paper are Piano Piece 1952, Intermission 5 and Extensions 3. The essay will be in the form of a comparative analysis, using set theory to draw relationships between the pitch structures in each composition.Ph.D.Includes bibliographical references (p. 46-47)by Paul Steven Undreine
Does the Current Account Matter?
No full textThe purpose of this paper is to investigate in detail the behavior of the current account in emerging economies, and in particular its role if any in financial crises. Models of current account behavior are reviewed, and a dynamic model of current account sustainability is developed. The empirical analysis is based on a massive data set that covers over 120 countries during more than 25 years. Important controversies related to the current account including the extent to which current account deficits help predict currency crises are also analyzed. Throughout the paper I am interested in analyzing whether there is evidence supporting the idea that there are costs involved in running 'very large' deficits. Moreover, I investigate the nature of these potential costs, including whether they are particularly high in the presence of other type of imbalances.

Problem solving and principal’s interaction with accountability
No full textPROBLEM: Increasing accountability in public schools has created a new set of problems for school leaders. With the prominence of high stakes testing, the pressure to make Adequate Yearly Progress, accountability for closing the achievement gap of every subgroup of students, the demand for a highly qualified faculty and related pressures from school boards and communities, school leaders are faced with an array of unstructured, complex problems. Set within a rich literature on educational leadership and the relatively unexplored literature on problem solving, this study examines the school principal’s interaction with the problems created by accountability to determine how expert leaders perceive, approach, and engage others in addressing complex problems. Three areas of interaction are explored (Leader Capacity, Leader Response and Organizational Response) in order to address the following questions: * Does the mental model of the expert principal differ from a more typical principal as it relates to problem solving? * How do leaders’ beliefs, conceptions of problems, and knowledge influence their response in problem solving? * How does the problem solving capacity of the expert school leader differ from that of the non-expert? * Are there leader responses to problems created by accountability that offer the best possibility of school success? METHOD: A total sample of 24 New Jersey middle school principals were selected using a regression analysis of three years of New Jersey data from within four quadrants of performance: High Socio Economic Status (SES) and higher than predicated performance, low SES and higher than predicted performance, high SES and lower than predicated performance, low SES and lower than predicated performance. These principals must have been leaders in their respective schools for at least two years permitting their school’s performance to serve as a proxy for expertise. Once selected, principals were interviewed by two researchers using an in-depth guide in order to probe areas of interest in the study. The data from the 24 interviews was coded using a qualitative software package and analyzed according to the conceptual framework serving as the basis of discussion and findings. FINDINGS: Differences exist between successful principals and typical principals with respect to approaching and resolving complex problems. This study finds patterns of influence that are significant in capturing attributes of successful school leadership. Specifically, more expert principals tend to operate with an inventive mindset that approaches problems with an open mind toward trying new avenues toward reform. Similarly these principals are more likely to set broad goals for a problem’s resolution and engage others in a substantive fashion. SIGNIFICANCE: Adding to the rich body of literature on school leadership by offering a construct for effective problem solving addresses an important area of study. In an era of increasing accountability, transparency, and complexity, identifying school leaders with the capacity to innovate and set broad goals for addressing the complex problems associated with student achievement is essential.Ed.

Error-Bounded Approximation of Pareto Fronts in Robot Planning Problems
No full textMany problems in robotics seek to simultaneously optimize several competing objectives under constraints. A conventional approach to solving such multi-objective optimization problems is to create a single cost function comprised of the weighted sum of the individual objectives. Solutions to this scalarized optimization problem are Pareto optimal solutions to the original multi-objective problem. However, finding an accurate representation of a Pareto front remains an important challenge. Using uniformly spaced weight vectors is often inefficient and does not provide error bounds. Thus, we address the problem of computing a finite set of weight vectors such that for any other weight vector, there exists an element in the set whose error compared to optimal is minimized. To this end, we prove fundamental properties of the optimal cost as a function of the weight vector, including its continuity and concavity. Using these, we propose an algorithm that greedily adds the weight vector least-represented by the current set, and provide bounds on the error. Finally, we illustrate that the proposed approach significantly outperforms uniformly distributed weights for different robot planning problems with varying numbers of objective functions.Green Open Access added to TU Delft Institutional Repository 'You share, we take care!' - Taverne project https://www.openaccess.nl/en/you-share-we-take-care Otherwise as indicated in the copyright section: the publisher is the copyright holder of this work and the author uses the Dutch legislation to make this work public.Learning & Autonomous Contro
