A dynamic vertical partitioning approach for distributed database system

Vertical and horizontal partitioning are physical database design techniques that can considerably improve query response time in distributed database system. Although most current database management systems support horizontal partitioning, they do not implement vertical partitioning bacause it is based on user queries and it is necessary to monitor queries in order to generate a good vertical partitioning solution. In this paper, we use active rules to develop an active system for dynamic vertical partitioning of distributed database. The system vertically fragment and re-fragment a database without intervention of a database administrator. Experiments on a Benchmark database TPC-H demonstrate acceptable query response time.
Examining the Internal Validity and Statistical Precision of the Comparative Interrupted Time Series Design by Comparison With a Randomized Experiment

Although evaluators often use an interrupted time series (ITS) design to test hypotheses about program effects, there are few empirical tests of the design’s validity. We take a randomized experiment on an educational topic and compare its effects to those from a comparative ITS (CITS) design that uses the same treatment group as the experiment but a nonequivalent comparison group that is assessed at six time points before treatment. We estimate program effects with and without matching of the comparison schools, and we also systematically vary the number of pretest time points in the analysis. CITS designs produce impact estimates that are extremely close to the experimental benchmarks and, as implemented here, do so equally well with and without matching. Adding time points provides an advantage so long as the pretest trend differences in the treatment and comparison groups are correctly modeled. Otherwise, more time points can increase bias.
Applying theory-driven evaluation to the British Crime Reduction Programme

The Crime Reduction Programme began in April 1999 and was largely finished by March 2002. It went through a number of major changes. It also incorporated an ambitious initial evaluation component and a range of forms of evaluation activity. This article traces the changing theories in and of the programme as a whole and the changing forms of evaluation that were conducted under its auspices. It attempts to explain how and why the programme metamorphosed and how and why provisions for evaluation activity evolved as they did. It tries to distil realistic lessons for the conduct of informative evaluation in the context of large-scale government programmes. It also attempts to locate the potential for realist evaluation within such programmes.
Extended Time Constraints for Sequence Mining

Many applications require techniques for temporal knowledge discovery. Some of those approaches can handle time constraints between events. In particular some work has been done to mine generalized sequential patterns. However, such constraints are often too crisp or need a very precise assessment to avoid erroneous information. Therefore, in this paper we propose to soften temporal constraints used for generalized sequential pattern mining. To handle these constraints while data mining, we design an algorithm based on sequence graphs. Moreover, as these relaxed constraints may extract more generalized patterns, we propose temporal accuracy measure for helping the analysis of the numerous discovered patterns.
Ore‐type degree conditions for a graph to be H‐linked

Given a fixed multigraph H with V(H) = {h1,…, hm}, we say that a graph G is H‐linked if for every choice of m vertices v1, …, vm in G, there exists a subdivision of H in G such that for every i, vi is the branch vertex representing hi. This generalizes the notion of k‐linked graphs (as well as some other notions). For a family ${\cal H}$ of graphs, a graph G is ${\cal H}$‐linked if G is H‐linked for every $H\in {\cal H}$. In this article, we estimate the minimum integer r = r(n, k, d) such that each n‐vertex graph with $\sigma_{2}(G)\ge {r}$ is ${\cal H}$‐linked, where ${\cal H}$ is the family of simple graphs with k edges and minimum degree at least $d \ge 2$. © 2008 Wiley Periodicals, Inc.

Police and domestic sex trafficking of youth: what teens tell us that can aid prevention and interdiction

Juveniles are more likely to come into contact with the criminal or juvenile justice systems in the USA as victims than as offenders. Yet, except in the case of child victims of sexual abuse at the hands of a family member, juveniles as victims still receive little attention in the criminal justice literature. And, for the most part, the actors in the justice system in the USA have not been given the skills, tools, and resources to effectively deal with juveniles, especially teenaged-youth, as victims. Furthermore, policing of domestic sex trafficking of youth has focused on police response at later stages of sex trafficking (when such a crime is clearly identified) and the role of the police in coordinated response teams and building cases against the perpetrators including ‘pimps. ’ This article offers evidence from research on commercial sexual exploitation of adolescents to examine police interactions with youth who are at a high risk for or on the pathway into domestic sex trafficking and identifies prevention and interdiction strategies. Notably, these strategies reflect the connection of police responses to domestic violence, youth status offenses, and homeless teens.
A robot hand driven by hydraulic cluster actuators

To enable a humanoid robot to use its hand in the whole body motions, such as hanging, climbing or using a ladder, we developed a robot hand driven by a powerful but backdrivable cluster EHA. A miniature crescent trochoid pump with high discharging pressure was developed. The design of a direct casted cylinder manifold with low hydraulic friction is also presented. Results of basic experiments such as maximum output force, speed, position and force controllability and backdrivability are shown in the end of this paper. A movie of grasping demonstration is also attached.
Sxd at Mbar Pressures Synchrotron Radiation Advances in Array Detectors for X-ray Diffraction Techniques

Improved focal plane array detector systems are described which can provide improved readout speeds, random addressing and even be employed to simultaneously measure position, intensity and energy. This latter capability promises to rekindle interests in Laue techniques. Simulations of three varieties of foil mask spectrometer in both on-and off-axis configurations indicate that systems of stacked silicon detectors can provide energy measurements within 1% of the true value based on the use of single 'foils' and $ 10000 photons. An eight-detector hybrid design can provide energy coverage from 4 to 60 keV. Energy resolution can be improved by increased integration time or higher flux experiments. An off-axis spectrometer design in which the angle between the incident beam and the detector system is 45 results in a shift in the optimum energy response of the spectrometer system. In the case of a 200 mm-thick silicon absorber, the energy optimum shifts from 8.7 keV to 10.3 keV as the angle of incidence goes from 0 to 45. These new designs make better use of incident photons, lower the impact of source flicker through simultaneous rather than sequential collection of intensities, and improve the energy range relative to previously reported systems.
Hypnotic imagery as an adjunct to therapy for Irritable Bowel Syndrome: an experimental case report

Irritable bowel syndrome (IBS) is a debilitating condition affecting between 14 and 25% of the general population. Medication has been reported to be of limited efficacy. However, there is increasing evidence suggesting that hypnotic imagery can be an effective adjunct to therapy for this problem. The present experimental single case study aims to illustrate the process of psychological treatment of IBS with the adjunct of hypnosis and to explore the effectiveness of particular interventions. Over 10 sessions of treatment an overall reduction of 64% was seen in primary IBS symptoms. At 9-months follow-up this had improved further to a 72% reduction in primary symptoms and lower anxiety levels. The marked improvement seen with this client is consistent with the view that hypnosis is an effective adjunct to IBS treatments. Copyright © 2006 British Society of Experimental & Clinical Hypnosis.

A Contribution to Validation of Score Meaning for Felder- Soloman's Index of Learning Styles

In 1988, Richard Felder and Linda Silverman developed a learning model that focuses specifically on aspects of learning styles of engineering students. Three years later, a corresponding psychometric assessment instrument, the Felder-Soloman’s Index of Learning Styles, was developed. This paper offers a contribution to an ongoing validation work on the ILS instrument, based on the author’s three-year study of the relationship between student learning styles and their academic achievement in hypermedia-assisted learning environment. The paper provides an analysis of psychometric properties of the ILS, based on the scores for 557 valid questionnaires collected in the study. This includes test-retest reliability, factor structure, internal reliability, total item correlation and inter-scale correlation. Construct validity is also discussed. In summary, the author supports conclusions found in the literature pointing to the ILS as a suitable psychometric tool for evaluating learning styles of engineering students. The author also concurs in recommendations for further work on validating the meaning of its scores and on improving the specific items to reduce inter-scale correlation.
Anekāntavāda and Engaged Rhetorical Pluralism: Explicating Jaina Views on Perspectivism, Violence, and Rhetoric

This study represents a detailed inquiry into the rhetoric of Jainism, an understudied religious-philosophical tradition that arose among Hinduism and Buddhism on the Indian subcontinent. Exploring the unique use of pluralism in Jaina authors such as Mahāvīra and Haribhadra, I advance the concept of engaged rhetorical pluralism to account for the argumentative use of pluralism to promote Jaina views. This concept is linked to Jainism’s theory of multiperspectivism (anekāntavāda) as an orientation toward one’s rhetorical activities in contexts of disagreement. Highlighting the controversies surrounding the relationship between Jaina tolerance and intellectual nonviolence, this study uses the concept of anekāntavāda to ground a pluralism of often contradictory critical claims made by those studying rhetorical phenomena from other cultures. Thus, anekāntavāda both describes the engaged pluralism evident in important Jaina rhetors and serves as a source of methodological guidance for scholars involved in comparative rhetoric and its inevitable situations of interpretative disagreement.
Efficient Software-Based Runtime Binary Translation for Coarse-Grained Reconfigurable Architectures

The increasing use of runtime-compiled applications provides an opportunity for coarse-grained reconfigurable architecture (CGRA) accelerators to be used in a user-transparent way. The challenge is to provide efficient runtime translation for CGRAs. Despite the apparent difficulties stemming from the heterogeneous nature of CGRAs, this paper demonstrates that it is possible to speed up runtime-compiled applications using CGRAs in a runtime-complied way. In particular this paper presents a runtime translation framework, called RBTVM, for CGRA accelerators, based on the LLVM Just-In-Time (JIT) compiler. Also two optimizations for the RBTVM are proposed. Experimental results show that the proposed RBTVM approach can improve the performance of runtime-compiled applications by 1.44 times on average compared to using the baseline JIT compiler only that does not take advantage of the accelerator, demonstrating the efficacy of the proposed approach.
Marcadores neurobiológicos e psicométricos da eficácia da terapia cognitivo-comportamental no transtorno de estresse pós-traumático associado a sintomas dissociativos: relato de caso

INTRODUCAO: O transtorno de estresse pos-traumatico (TEPT) tem sido associado a desregulacao de diversos parâmetros psicofisiologicos e pode apresentar comorbidade com diversas psicopatologias, inclusive a dissociacao, podendo dificultar o tratamento. O objetivo do presente trabalho foi investigar os efeitos da terapia cognitivo-comportamental em um paciente com TEPT e sintomas dissociativos com base em medidas psicofisiologicas e psicometricas em diferentes momentos do tratamento. DESCRICAO DO CASO: O paciente e um homem de 38 anos, com diagnosticos de TEPT e transtorno depressivo maior recorrente com sintomas dissociativos e resistencia ao tratamento farmacologico. O tratamento psicoterapico teve duracao de 4 meses, sendo composto por uma sessao semanal de terapia e tres sessoes semanais de coterapia. Os parâmetros fisiologicos (frequencia cardiaca, tonus vagal, balanco simpatico e cortisol) e psicometricos (afeto negativo e positivo, resiliencia e sintomas de estresse pos-traumatico, depressao, ansiedade e dissociacao) foram medidos antes, durante (uma vez ao mes) e apos o tratamento. COMENTARIOS: Os resultados mostraram diminuicao do balanco simpatico e aumento do tonus vagal, da frequencia cardiaca e dos niveis de cortisol ao longo do tratamento. O tratamento tambem promoveu reducao no afeto negativo e nos sintomas de estresse pos-traumatico, depressao, ansiedade e dissociacao, alem de um aumento nos escores de resiliencia, apoio social e afeto positivo. Esses resultados sugerem que a terapia cognitivo-comportamental e um tratamento eficaz para o TEPT com sintomas dissociativos. Alem disso, parece promover a normalizacao das alteracoes fisiologicas do sistema nervoso autonomo e neuroendocrino relacionadas ao TEPT.
General Untimed Sequential Automata Models for the General Components of Automatic Transport Systems with Accumulation Areas

Discrete event systems have been researched for quite a while in the domain literature. A series of modelling and analysis techniques have been used. Sequential automata models are at the basis of their studies and theories have been born to provide tools for their design. Automatic transport systems with accumulation areas are a particular type of systems where the sequential automata model can be successfully used. The aim of this paper is to establish connections between a sequential automata model and a Petri net model: first for a node with ";one"; input and ";m"; outputs and the second for a node with ";n "; inputs and ";m "; outputs, using basic elements of the automatic transport systems with accumulation areas. General models for an automatic transport system with accumulation areas are obtain by composing sub-models. In this paper, untimed sequential automata and untimed Petri nets have been used for modelling, time being not a defining element for this modelling.
ACHIEVING ADVANTAGES FROM BUSINESS-TO-BUSINESS ELECTRONIC COMMERCE: THE ROLE OF THE FIRMS STRATEGY AND THE TYPE OF USE

Key findings indicate that the most important advantages of B2B EC are increased productivity, increased quality of products and services, competitive advantage, and to a lesser extent, sales growth and increased revenues. Cost reductions are marginal. In addition, the type of B2B EC use has a direct effect on B2B EC advantages. The strategic orientation of the firm exerts an indirect effect on B2B EC advantages. More specifically, the strategic orientation has a direct effect on the type of B2B EC use which in turn has a direct effect on the advantages.

Trends in gender disparities at the transition from school to work: labour market entries of young men and women between 1984 and 2005 in West Germany

This paper examines trends in school-to-work transitions of young men and women with lower and higher secondary education in West Germany between 1984 and 2005. This period was marked by an increase in young women’s educational attainment and a continuous growth of the service sector. We assume that both developments have benefited women more than men in terms of smooth labour market integration. Results from discrete event history analyses show that in recent years women indeed found their first job faster than men. However, this is not mainly due to an improvement in young women’s chances to enter employment, but to deteriorating employment prospects of men, in particular of unskilled men.
Between the Book and the Lamp: Imaginative Geographies of Egypt, 1849-50

This essay compares the imaginative geographies of Egypt produced by Florence Nightingale and Gustave Flaubert as they travelled up the Nile Valley and back to Cairo in 1849-50. Their experiences are used to emphasize the physicality (rather than merely the textuality) of travel writing. The differences between their imaginative geographies and in particular between their representations of landscape, space and people, illuminate the complex and fractured formation of Orientalism as a constellation of power, knowledge and spatiality, and its entanglements with patriarchy, sexuality and various colonialisms.
Modeling Identity in Archival Collections of Email: A Preliminary Study

Access to historically significant email archives poses challenges that arise less often in personal collections. Most notably, searchers may need help making sense of the identities, roles, and relationships of individuals that participated in archived email exchanges. This paper describes an exploratory study of identity resolution in the public subset of the Enron collection. Addressname and address-address associations in explicit, embedded and implied email headers are augmented with name and nickname associations discovered from consistent use in salutations and signatures. Limited transitive closure heuristics are employed to extend pair-wise associations to richer representations of identity. Assessment of sampled results indicates that many potentially useful nontrivial associations can be detected.
Curve Matching on Brain Surfaces Using Induced Frenet Distance Metrics

This paper describes methods for diieomorphic matching of curves on brain surfaces. Distance metrics between curves are deened by the Frenet representation via speed, curvature and torsion. The curve matching algorithm is based on the bipar-tite graph matching with weights deened by the Frenet distance over diieomorphic maps of one curve onto the other. 1]. We follow Khaneja 2] and deene fundus curves on the brain surfaces as extremal curvature lines generated using dynamic programming. Examples are shown for fundus curve matchings on macaque brain surfaces.
Studies in Substance Memorization

Resume On a teste des etudiants universitaires pour leur reconnaissance-retention d'un passage de prose difficile au moyen de deux types contrastes de test: l'un reproduisant presque mot pour mot des portions du test, l'autre exigeant la reconnaissance de la signification exprimee en mots tout a fait differents. La frequence des repetitions (1–4 lectures du texte) a influe sur les portions mot pour mot mais non pas sur les autres portions. La reconnaissance des deux types a ete meilleure apres 24 heures que tout de suite, mais les portions mot pour mot ont montre apres une courbe d'oubli semblable a celle l'Ebbinghaus tandis que les autres portions n'ont pas ete oubliees, parait-il, dans les periods durant jusqu'a 70 jours et en quelques cas ont montre un gain statistiquement constant. On suppose que ces resultats indiquent que l'apprentissage du contenu differe non seulement de l'apprentissage des syllables non-sens mais aussi de l'apprentissage soidisant logique ou les mots du texte original sont preser.
On evaluating recommender systems for API usages

To ease framework understanding, tools have been developed that analyze existing framework instantiations to extract API usage patterns and present them to the user. However, detailed quantitative evaluations of such recommender systems are lacking. In this paper we present an automated evaluation process which extracts queries and expected results from existing code bases. This enables the validation of recommendation systems with large test beds in an objective manner by means of precision and recall measures. We demonstrate the applicability of our approach by evaluating an improvement of an existing API recommender tool that takes into account the framework-method context for recommendations.
Governance, Organization, and Democracy on the Internet: The Iron Law and the Evolution of Wikipedia

This study examines whether the Iron Law of Oligarchy exists in Wikipedia by analyzing how a key policy of the website regarding verifiability evolved into its current form. The study describes the decision-making processes of Wikipedia and shows that there are many factors preventing or slowing the development of oligarchy on Wikipedia. The study provides data advancing theoretical concepts related to the Iron Law of Oligarchy and the evolution of virtual communities and organizations; results and knowledge gained can also improve Wikipedia policies related to verifiability. Michels wrote: "who says organization, says oligarchy. " I argue that we should follow this with a caveat: "who says wiki-organization, says no to oligarchy. "
Thin Layer Chromatography for the Separation and Analysis of Acidic Carbohydrates

Abstract Thin layer chromatography (TLC) is routinely used by synthetic organic chemists and natural products chemists working on a variety of types of molecules. Carbohydrate chemists and biochemists in the past largely relied on paper chromatography for rapid and inexpensive analysis. Carbohydrates are highly polar molecules and often require derivatization to be analyzed by TLC. Acidic carbohydrates pose an even more difficult challenge as they contain a formal negative charge and counterion, and can interact with commonly used stationary phases. This review describes TLC methods that have been developed for the analysis of acidic monosaccharides, disaccharides, and oligosaccharides derived from natural sources.
