Social Recommendation GIS for Urban Tourist Spots

Since the amount of information submitted and made public about tourist spots in urban areas is very large compared to that for regional tourist spots, it is difficult for people who do not have much knowledge of or acquaintance with the places concerned to efficiently obtain information necessary for taking tourist trips. This study aims to develop a social recommendation media GIS (Geographic Information Systems) specially tailored to recommend tourist spots in urban areas. The conclusions of this study are summarized in the following three points. (1) Social recommendation GIS, an information system which integrates a Web-GIS, an SNS (Social Networking Service) and a recommendation system into a single system, was operated in the central part of Yokohama City in Kanagawa Prefecture, Japan. The social recommendation GIS uses a design to make it possible to redesign systems in accordance with target cases. (2) The social recommendation GIS was operated for two months for members of the general public who are more than 18 years old. The total numbers of users was 98, and the number of pieces of information submitted was 232. (3) The web questionnaire to users showed the usefulness of the integration of a Web-GIS, an SNS and a recommendation systems, because the functions of reference and recommendation can be expected to support tourists' excursion behavior. Since the access survey of log data showed that about 35% of accesses were from mobile information terminals, it can be said that the preparation of an optimal interface for such terminals was effective.
QUESTIONED ELECTRONIC DOCUMENTS : EMPIRICAL STUDIES IN AUTHORSHIP ATTRIBUTION

Forensic analysis of questioned electronic documents is very difficult, because the nature of the documents eliminates many kinds of informative differences. Recent work in authorship attribution demonstrates the practicality of analyzing documents based on authorial style, but the state of the art is confusing. Analyses are difficult to apply, little is known about type or rate of errors, and no “best practices” are available. We present the results of some recent experiments and software development to address these issues, partly through the development of a systematic testbed for multilingual, multigenre authorship attribution accuracy, and partly through the development and concurrent analysis of a uniform and portable software tool that applies multiple methods to analyze electronic documents for authorship based on authorial style.
How Bad Are Selfish Investments in Network Security?

We study a network security game where strategic players choose their investments in security. Since a player's investment can reduce the propagation of computer viruses, a key feature of the game is the positive externality exerted by the investment. With selfish players, unfortunately, the overall network security can be far from optimum. The contributions of this paper are as follows. 1) We first characterize the price of anarchy (POA) in the strategic-form game under an “Effective-investment” model and a “Bad-traffic” model, and give insight on how the POA depends on individual players' cost functions and their mutual influence. We also introduce the concept of “weighted POA” to bound the region of payoff vectors. 2) In a repeated game, players have more incentive to cooperate for their long term interests. We consider the socially best outcome that can be supported by the repeated game, as compared to the social optimum. 3) Next, we compare the benefits of improving security technology and improving incentives, and show that improving technology alone may not offset the price of anarchy. 4) Finally, we characterize the performance of correlated equilibrium (CE). Although the paper focuses on network security, many results are generally applicable to games with positive externalities .
The Major Findings Are :

Total factor productivity (TFP) is the broadest measure of productivity. It compares the total output of a sector to the total land, labor, capital, and material inputs used to produce that output. Increases in TFP imply more output is forthcoming from a given level of inputs, or, equivalently, fewer inputs are required to produce the same output. Growth in TFP is considered to be an indicator of the rate of technical change in a sector.
Under Consideration for Publication in Theory and Practice of Logic Programming Well-founded and Stable Semantics of Logic Programs with Aggregates

In this paper, we present a framework for the semantics and the computation of aggregates in the context of logic programming. In our study, an aggregate can be an arbitrary interpreted second order predicate (or function). We define extensions of the Kripke-Kleene, the well-founded and the stable semantics for aggregate programs. The semantics is based on the concept of a three-valued immediate consequence operator of an aggregate program. Such an operator approximates the standard two-valued immediate consequence operator of the program, and induces a unique Kripke-Kleene model, a unique well-founded model and a collection of stable models. We study different ways of defining such operators and thus obtain a framework of semantics, offering different trade-offs between precision and tractability. In particular, we investigate conditions on the operator that guarantee that the computation of the three types of semantics remains on the same level as for logic programs without aggregates. Other results show that, in practice, even efficient three-valued immediate consequence operators which are very low in the precision hierarchy, still provide optimal precision.
The influence of culture and professional judgment on accounting: an analysis from the perspective of information preparers in Portugal

The standards issued by the International Accounting Standards Board (Iasb) are based on principles, which delegate decisions on accounting matters to professional judgment, based on the concepts existing in those standards, with implications for financial reporting. The objective in this study is to analyze the influence of culture on professional judgment, through the analysis of the existence of significant differences in the decisions about the disclosure or recognition of liabilities and assets, as well as to validate (or not) the classification Gray (1988) attributed to Portugal concerning the accounting values of conservatism and secrecy. In that sense, the concepts established in Accounting and Financial Reporting Standard (NCRF) 21, entitled Provisions, Contingent Liabilities and Contingent Assets. Based on the distribution of a questionnaire to the information preparers, which resulted in a sample of 408 professionals, it could be identified through the use of bivariate statistical techniques that there are significant differences in the professionals’ perception of asset and liability disclosure and recognition, revealing a stronger trend towards the disclosure or recognition of liabilities. Concerning conservatism and secrecy, using multivariate statistical techniques, a higher level of conservatism could be verified as an accounting value in Portugal, as well as the existence of an association between conservatism and secrecy. This study attracts standardizing entities’ attention to the importance of aspects related to the information disclosed in the financial statements, particularly regarding the professional judgment.
Black and Belonging at School: A Case for Interpersonal, Instructional, and Institutional Opportunity Structures

This article is guided by two goals: (a) to consider how race-based perspectives can serve as theoretical tools for investigating Black adolescents’ opportunities to belong at school, and (b) to describe cultural and political aspects of schooling that can support a sense of belongingness among Black adolescents. We discuss support for the belonging of Black adolescents in terms of interpersonal, instructional, and institutional opportunity structures. We provide a set of guiding questions for scholars seeking to advance educational psychology research at the intersection of race, belonging, and motivation. We end by describing specific research directions for an inclusive examination of school belonging, along with strategies to accomplish this goal.
Notice of RetractionModeling the interactive effects between urbanization and higher education

The processes and spatial distributions of urbanization and higher education in Jiangxi province are been analyzed, and the interactive effects of them been estimated by means of econometrics method. The results show: Firstly, both urbanization and higher education significantly developed after the reforming and opening up, but there is a tendency of spatial aggregation; Secondly, there is a two-way granger relationship between urbanization and higher education in Jiangxi province, in which the partial logarithm modeling is been quantified; Thirdly, there is a spatial corresponding relationship between urbanization level and scale of higher education, but there is not a compatibility characteristic of their spatial growth. Therefore, not only should the priority districts be specially developed, but also the spatial distributions of the higher education be adjusted according to the demand of urbanization stage and poplar higher education.
Mutual information and intrinsic dimensionality for feature selection

In this article we proposed a feature selection method based on mutual information (MI) and intrinsic dimensionality (ID) estimators. First, MI ranks the normalized feature space in accordance to minimal-redundancy-maximal-relevance (mRMR) criterion. Next, ID estimates the minimum number of features to represent the observed properties of the data. Two techniques of ID were tested: principal component analysis (PCA) and maximum likelihood estimator (MLE). Support vector machine (SVM) was used to classify five medical datasets. Receiver operating characteristics (ROC) analysis evaluated the classification performance before and after feature selection. Results showed that MI and ID are effective techniques for feature selection to reduce the classification error.
Intravenous Drug Users Can Achieve a High Sustained Virological Response Rate: experience From Croatian Reference Center for Viral Hepatitis

Background Hepatitis C virus (HCV) is one of the major infectious disease agents among injecting drug users (IVDUs). However, most of the IVDUs are not still treated. Objectives To examine the treatment course, adherence, tolerability and safety profiles and SVR rates in IVDUs compared to non-IVDUs. Patients and Methods Demographic and clinical data were collected from medical records of 345 adult patients diagnosed with chronic hepatitis C (CHC) who were treated with a PEG-IFN-α and ribavirin in Croatian Reference Center for Viral Hepatitis in Zagreb between January 2003 and January 2010. Efficacy, safety and tolerability treatment profiles were analyzed in IVDUs vs. non-IVDUs. Positive predictors for treatment outcome were evaluated by univariate and multivariate logistic regression. Results A total of 106 (30.46%) IVDUs were identified. The IVDUs were mainly male (81.13% vs. 52.30%, P = 0.0001), young (mean ± SD age: 32.46 ± 5.33 y vs. 46.12 ± 11.48 y, P = 0.0001), had lower fibrosis and HAI score (measured by ISHAK) and shorter duration of infection (mean ± SD: 8.98 ± 5.87 vs. 16.79 ± 8.99 y, P = 0.0001) compared to non-IVDU group. In IVDUs, genotype 1a (24.52%) and 3a (38.68%) were predominant. There were no differences in completion rate between the two studied groups. IVDUs achieved a significantly higher rate of overall SVR (70.75% vs. 51.04%, P < 0.0009) and in genotypes 1 and 4 (65.08% vs. 48.73%, P = 0.0294) vs. non-IVDUs. Treatment discontinuation rates due to side-effects were not significantly different in IVDUs and non-IVDUs (2.83% vs. 7.11%, P = 0.1390). IVDU group had a higher rate of lost to follow-up (13.21% vs. 4.60%, P = 0.0071). There were no statistically significant differences in SVR rate between IVDUs with, or without substitution therapy (55.55% vs. 74.62%, P = 0.0866). Independent predictors of SVR were age < 40 years and genotypes 2 and 3. Type of PEG-IFN-α used was not associated with SVR. Conclusions Treatment of CHC in IVDUs should strongly be encouraged as they have positive predictors for achieving SVR such as younger age, shorter duration of infection, and consequently favorable histological stage of the disease, and good adherence to treatment. There is no difference in safety and tolerability profiles of treatment in IVDUs compared to patients with no history of drug abuse.
Clustering provenance facilitating provenance exploration through data abstraction

As digital objects become increasingly important in people's lives, people may need to understand the provenance, or lineage and history, of an important digital object, to understand how it was produced. This is particularly important for objects created from large, multi-source collections of personal data. As the metadata describing provenance, Provenance Data, is commonly represented as a labelled directed acyclic graph, the challenge is to create effective interfaces onto such graphs so that people can understand the provenance of key digital objects. This unsolved problem is especially challenging for the case of novice and intermittent users and complex provenance graphs. We tackle this by creating an interface based on a clustering approach. This was designed to enable users to view provenance graphs, and to simplify complex graphs by combining several nodes. Our core contribution is the design of a prototype interface that supports clustering and its analytic evaluation in terms of desirable properties of visualisation interfaces.
Comorbid Depression, Chronic Pain, and Disability in Primary Care

Objectives: The objectives of this study were to provide estimates of the prevalence and strength of association between major depression and chronic pain in a primary care population and to examine the clinical burden associated with the two conditions, singly and together. Methods: A random sample of Kaiser Permanente patients who visited a primary care clinic was mailed a questionnaire assessing major depressive disorder (MDD), chronic pain, pain-related disability, somatic symptom severity, panic disorder, other anxiety, probable alcohol abuse, and health-related quality of life (HRQL). Instruments included the Patient Health Questionnaire, SF-8, and Graded Chronic Pain Questionnaire. A total of 5808 patients responded (54% of those eligible to participate). Results: Among those with MDD, a significantly higher proportion reported chronic (i.e., nondisabling or disabling) pain than those without MDD (66% versus 43%, respectively). Disabling chronic pain was present in 41% of those with MDD versus 10% of those without MDD. Respondents with comorbid depression and disabling chronic pain had significantly poorer HRQL, greater somatic symptom severity, and higher prevalence of panic disorder than other respondents. The prevalence of probable alcohol abuse/dependence was significantly higher among persons with MDD compared with individuals without MDD regardless of pain or disability level. Compared with participants without MDD, the prevalence of other anxiety among those with MDD was more than sixfold greater regardless of pain or disability level. Conclusions: Chronic pain is common among those with MDD. Comorbid MDD and disabling chronic pain are associated with greater clinical burden than MDD alone. MDD = major depressive disorder; HRQL = health-related quality of life; HMO = health maintenance organization; PHQ = Patient Health Questionnaire; GCPS = Graded Chronic Pain Scale; CP = chronic pain; DCP = disabling chronic pain; GAD = generalized anxiety disorder; SCID = Structured Clinical Interview for DSM-III-R; PRIME-MD = Primary Care Evaluation of Mental Disorders; CI = confidence interval; DSM-IV = Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition; DSM-III-R = Diagnostic and Statistical Manual of Mental Disorders, Third Edition Revised.

Beating the spread: time-optimal point meshing

We present NetMesh, a new algorithm that produces a conforming Delaunay mesh for point sets in any fixed dimension with guaranteed optimal mesh size and quality. Our comparison-based algorithm runs in O(n log n + m) time, where n is the input size and m is the output size, and with constants depending only on the dimension and the desired element quality. It can terminate early in O(n log n) time returning a O(n) size Voronoi diagram of a superset of P, which again matches the known lower bounds. The previous best results in the comparison model depended on the log of the spread of the input, the ratio of the largest to smallest pairwise distance. We reduce this dependence to O(log n) by using a sequence of ε-nets to determine input insertion order into a incremental Voronoi diagram. We generate a hierarchy of well-spaced meshes and use these to show that the complexity of the Voronoi diagram stays linear in the number of points throughout the construction.
Visual localization by linear combination of image descriptors

We seek to predict the GPS location of a query image given a database of images localized on a map with known GPS locations. The contributions of this work are three-fold: (1) we formulate the image-based localization problem as a regression on an image graph with images as nodes and edges connecting close-by images; (2) we design a novel image matching procedure, which computes similarity between the query and pairs of database images using edges of the graph and considering linear combinations of their feature vectors. This improves generalization to unseen viewpoints and illumination conditions, while reducing the database size; (3) we demonstrate that the query location can be predicted by interpolating locations of matched images in the graph without the costly estimation of multi-view geometry. We demonstrate benefits of the proposed image matching scheme on the standard Oxford building benchmark, and show localization results on a database of 8,999 panoramic Google Street View images of Pittsburgh.

Most students considered it is important but most students has admitted that they have commits fraud based on the type of fraud internal. A student who work in the bank, student semester 1 and semester 3, Students who have received lecture business ethics and student man Dominated in the category of fraud. Limitations of this study is sample use only students of the night class of accounting study program in Batam alone. The provision of the science more in-depth about ethics business and also study of ethics are need to. Suggestions for further research is sample examined across extend, can add external factors that determines fraud behavior and for research on fraud that has happened.
A Hybrid Approach to Machine Translation System Design

It is difficult for pure statistics-based machine translation systems to process long sentences. In addition, the domain dependent problem is a key issue under such a framework. Pure rule-based machine translation systems have many human costs in formulating rules and introduce inconsistencies when the number of rules increases. Integration of these two approaches reduces the difficulties associated with both. In this paper, an integrated model for machine translation system is proposed. A partial parsing method is adopted, and the translation process is performed chunk by chunk. In the synthesis module, the word order is locally rearranged within chunks via the Markov model. Since the length of a chunk is much shorter than that of a sentence, the disadvantage of the Markov model in dealing with long distance phenomena is greatly reduced. Structural transfer is fulfilled using a set of rules; in contrast, lexical transfer is resolved using bilingual constraints. Qualitative and quantitative knowledge is employed interleavingly and cooperatively, so that the advantages of these two approaches can be retained.
1 Based on observations made with the NASA/ESA Hubble Space Telescope, which is

We have detected likely z ∼ 7 − 8 galaxies in the 144 ′′ × 144 ′′ NICMOS observations of the Hubble Ultra Deep Field. Objects are required to be ≥ 3σ detections in both NICMOS bands, J 110 and H 160. The selection criteria for this sample are (z 850 − The 5 selected sources have total magnitudes H 160,AB ∼ 27. Four of the five sources are quite blue compared to typical lower–redshift dropout galaxies and are clustered within a 1 ⊓ ⊔ ′ region. Because all 5 sources are near the limit of the NICMOS data, we have carefully evaluated their reality. Each of the candidates is visible in different splits of the data and a median stack. We analyzed several noise images and estimate the number of spurious sources to be 1 ± 1. A search using an independent reduction of this same data set clearly revealed 3 of the 5 candidates and weakly detected a 4th candidate, suggesting the contamination could be higher. For comparison with predictions from lower redshift samples we take a conservative approach and adopt four z ∼ 7 − 8 galaxies as our sample. With the same detection criteria on simulated datasets, assuming no-evolution from z ∼ 3.8, we predict 10 sources at z ∼ 7 − 8, or 14 if we use a more realistic (1 + z) −1 size scaling. We estimate that the rest-frame continuum UV (∼ 1800Å) luminosity density at z ∼ 7.5 (integrated down to 0.3L
Guaranteed Computational Resprinting via Model-Predictive Control

Today and future many-core systems are facing the utilization wall and dark silicon problems, for which not all the processing engines can be powered at the same time as this will lead to a power consumption higher than the Total Design Power (TDP) budget. Recently, computational sprinting approaches addressed the problem by exploiting the intrinsic thermal capacitance of the chip and the properties of common applications, which require intense, but temporary, use of resources. The thermal capacitance, possibly augmented with phase change materials, enables the temporary activation of all the resources simultaneously, although they largely exceed the steady-state thermal design power. In this article, we present an innovative and low-overhead hierarchical model-predictive controller for managing thermally safe sprinting with predictable resprinting rate, which ensures the correct execution of mixed-criticality tasks. Well-targeted simulations, also based on real workload benchmarks, show the applicability and the effectiveness of our solution.
