TOPIC BASED QUERY SUGGESTION USING HIDDEN TOPIC MODEL FOR EFFECTIVE WEB SEARCH

Keyword-based web search is widely used for locatin g information on the web. But, web users lack sufficient domain knowledge and find it difficult t o organize and formulate input queries which affect search performance. Existing method suggests terms using the statistics in the documents, query logs a nd external dictionaries. This novel query suggestion method suggests terms related to topics present in the input query and re-rank the retrieved documents. A generative model, Latent Dirichlet Allocation (LDA) is used to learn the topics from the underlying docume nts. The high probability words in a topic are sele cted using the Kullback liebler(KL) divergence measure and presented to the user for suggestion, to enrich the user query and to narrow the search. The re-rankin g technique of this approach uses the initial retri eval position of the document to re-rank the documents. The suggested queries by the hidden topic approach and by keyword search are analysed.
Extending context models for privacy in pervasive computing environments

Privacy is widely recognised as a significant obstacle inhibiting the adoption of context-aware applications. In order to remove this obstacle, advances are required in many areas of context-awareness research. In this paper, we address the incorporation of privacy support into context models. In particular, we present extensions to our context modelling approach that address the challenges of assigning ownership to context information and enabling users to express privacy preferences for their own information.
Determinants of Capital Structure : Evidence from Libya

This paper provides further evidence of the capital structure theories pertaining to a developing country and examines the impact of the lack of a secondary capital market by analysing a capital structure question with reference to the Libyan business environment. The results of cross-sectional OLS regression show that both the static trade-off theory and the agency cost theory are pertinent theories to the Libyan companies’ capital structure whereas there was little evidence to support the asymmetric information theory. The lack of a secondary market may have an impact on agency costs, as shareholders who are unable to offload their shares might exert pressure on management to act in their best interests.
Communities of Practice at Work: Gender, Facework and the Power of Habitus at an All-Female Police Station and a Feminist Crisis Intervention Center in Brazil

This article investigates discursive practices and their relations to gender, facework and workplace in two all-female institutions that address violence against women in Brazil. By investigating 26 audio-taped interactions with victims of domestic violence at an all-female police station and a feminist activist crisis intervention center, this study contributes to the understanding of intragender differences. The findings suggest that gender does not predict interactional patterns; instead these interactional patterns are best understood as reflecting the gendered communities of practice from which the professionals are drawn. Police officers attend less to the victims' needs by providing minimal feedback when the victims report their problems. They are four times more likely than feminists to provide non-responses to the victims' turns, as well as four times more likely to change topics in their responses to the victims' turns. The linguistic and ethnographic findings suggest that the more cooperative strategies used by the feminists are not as `valuable' for police officers in the symbolic market of their habitus. In the police system, a more affiliative way of relating to the female clientele seems to work against the female police officers and their aims, by reifying the essentialist ideology that affiliative interactions are `natural' to women, or that is all females can offer in the police system.
Convolutional maxout neural networks for low-resource speech recognition

Building speech recognition systems with limited data resources is a fast progressing topic. In this paper, we propose the convolutional maxout neural network acoustic model for low-resource speech recognition. There are three motivations for this model. The first is to make use of the prior knowledge of local speech spectrum features by applying the convolutional structures. The second is to shrink the model size and enable better optimization performance by using the maxout nonlinearity. The third is to enhance model generalization and control overfitting by applying the dropout training. All the three motivations compensate for the lack of training data. Experiments on a 24-hour subset of the Switchboard corpus show that the convolutional structure, the maxout nonlinearity and the dropout training all bring superior performances on this task, and the combination of the three technologies achieves over 10.0% relative improvements over a convolutional neural network baseline.
Acute intermittent hypoxia induced neural plasticity in respiratory motor control

Respiratory neural networks can adapt to rapid environmental change or be altered over the long term by various inputs. The mechanisms that underlie the plasticity necessary for adaptive changes in breathing remain unclear. Acute intermittent hypoxia (AIH)‐induced respiratory long‐term facilitation (LTF) is one of the most extensively studied types of respiratory plasticity. Acute intermittent hypoxia‐induced LTF is present in several respiratory motor outputs, innervating both pump muscles (i.e. diaphragm) and valve muscles (i.e. tongue, pharynx and larynx). Long‐term facilitation is present in various species, including humans, and the expression of LTF is influenced by gender, age and genetics. Serotonin plays a key role in initiating and modulating plasticity at the level of respiratory motor neurons. Recently, multiple intracellular pathways have been elucidated that are capable of giving rise to respiratory LTF. These mainly activate the metabolic receptors coupled to Gq (‘Q’ pathway) and Gs (‘S’ pathway) proteins. Herein, we discuss AIH‐induced respiratory LTF in animals and humans, as well as recent advances in our understanding of the synaptic and intracellular pathways underlying this form of plasticity. We also discuss the potential to use intermittent hypoxia to induce functional recovery following cervical spinal injury.
FemtoGraph : Lightweight Shared-Memory Graph Processing Framework

The emerging applications for large graphs in big data science and social networks has led to the development of numerous parallel or distributed graph processing applications. The need for faster manipulation of graphs has driven the need to scale across large core counts and many parallel machines. While distributed memory parallel systems continue to be used for high performance computing, some smaller systems make use of shared memory (SMP) and larger core counts. We have implemented a graph processing framework for shared memory systems capable of scaling past 48 parallel cores. This system leverages and scale to large core counts and provide a framework for later incorporating distributed processing across multiple nodes.
A New Look at Globular Cluster Colors in NGC 3311 and the Case for Exclusively Metal-rich Globular Cluster Systems

NGC 3311, the central cD galaxy in the Hydra Cluster, was previously thought to host the most metal-rich globular cluster system known. Ground-based Washington photometry had indicated the almost complete absence of the population of globular clusters near [Fe/H] ~ -1 dex; these globular clusters are normally dominant in the metallicity distribution functions of giant elliptical galaxies. Lacking the normal metal-poor globular cluster population, NGC 3311 was an outstanding exception among galaxies and was not easily understood under any of the current globular cluster formation scenarios. Our Hubble Space Telescope Wide Field Planetary Camera 2 data yield normal globular cluster colors and hence metallicities for this galaxy. We find a bimodal color distribution with peaks at (V-I)0 = 0.91 ± 0.03 and 1.09 ± 0.03, corresponding to [Fe/H] ~ -1.5 and -0.75 dex (somewhat dependent on the choice of the conversion relation between color and metallicity). We review the evidence for exclusively metal-rich globular cluster systems in other galaxies and briefly discuss the implications for our understanding of globular cluster and galaxy formation.
Enhancements to Model-reduced Fluid Simulation

We present several enhancements to model-reduced fluid simulation that allow improved simulation bases and two-way solid-fluid coupling. Specifically, we present a basis enrichment scheme that allows us to combine data driven or artistically derived bases with more general analytic bases derived from Laplacian Eigenfunctions. We handle two-way solid-fluid coupling in a time-splitting fashion---we alternately timestep the fluid and rigid body simulators, while taking into account the effects of the fluid on the rigid bodies and vice versa. We employ the vortex panel method to handle solid-fluid coupling and use dynamic pressure to compute the effect of the fluid on rigid bodies.
Study Of Multidomain Query Optimization And Answering

In queries having multiple domains it is seen that general purpose search engines are not able to answer multidomain queries and one of the domain is considered by specific search services but no integrated framework is obtainable. Queries which are answerable by combining knowledge from two or more domains are multidomain queries. This paper presents an overall view for multidomain queries on the web. It integrates different kind of services like web service, web search and combination of them. It introduces the well defined model for expressing query results in ranking order. Here the query tends to find the results with cross domain joins to address the solution for optimized answering of multidomain queries. This paper provides the survey for multidomain query answering with answers as an optimized solution to obtain better search results with using web services. Here the output is obtained by chunking the whole query in several domain and then combining the whole result. KeywordsMultidomain query, query optimization relevance, reranking, semantic score, web search, web service.
Radio link quality estimation in wireless sensor networks

Radio link quality estimation in Wireless Sensor Networks (WSNs) has a fundamental impact on the network performance and also affects the design of higher-layer protocols. Therefore, for about a decade, it has been attracting a vast array of research works. Reported works on link quality estimation are typically based on different assumptions, consider different scenarios, and provide radically different (and sometimes contradictory) results. This article provides a comprehensive survey on related literature, covering the characteristics of low-power links, the fundamental concepts of link quality estimation in WSNs, a taxonomy of existing link quality estimators, and their performance analysis. To the best of our knowledge, this is the first survey tackling in detail link quality estimation in WSNs. We believe our efforts will serve as a reference to orient researchers and system designers in this area.
Production and Characterization of Ehrlichia risticii, the Agent of Potomac Horse Fever, from Snails (Pleuroceridae: Juga spp.) in Aquarium Culture and Genetic Comparison to Equine Strains

ABSTRACT We report on the production and characterization of Ehrlichia risticii, the agent of Potomac horse fever (PHF), from snails (Pleuroceridae: Juga spp.) maintained in aquarium culture and compare it genetically to equine strains. Snails were collected from stream waters on a pasture in Siskiyou County, Calif. , where PHF is enzootic and were maintained for several weeks in freshwater aquaria in the laboratory. Upon exposure to temperatures above 22°C the snails released trematode cercariae tentatively identified as virgulate cercariae. Fragments of three different genes (genes for 16S rRNA, thegroESL heat shock operon, and the 51-kDa major antigen) were amplified from cercaria lysates by PCR and sequenced. Genetic information was also obtained from E. risticii strains from horses with PHF. The PCR positivity of snail secretions was associated with the presence of trematode cercariae. Sequence analysis of the three genes indicated that the source organism closely resembledE. risticii, and the sequences of all three genes were virtually identical to those of the genes of an equine E. risticii strain from a property near the snail collection site. Phylogenetic analyses of the three genes indicated the presence of geographical E. risticii strain clusters.
Analysis of Delayed Postpolypectomy Bleeding in a Colorectal Clinic

Purpose The colonoscopic polypectomy has become a valuable procedure for removing precursors of colorectal cancer, but some complications can be occurred. The most common complication after colonoscopic polypectomy is bleeding, which is reported to range from 1% to 6% and which can be immediate or delayed. Because the management of delayed postpolypectomy bleeding could be difficult, the use of preventive technique and reductions of risk factors are essential. Methods From January 2007 to December 2008, delayed hemorrhage occurred in 18 of the 1,841 polypectomy patients examined by one endoscopist. These cases were reviewed retrospectively for risk factors, pathologic findings, and treatment methods. Results Delayed bleeding occurred in 18/1,841 patients (0.95%). The mean age was 55.9 ± 10.9 years, and the male-to-female ratio was 8:1. The most common site was the right colon (11 cases, 61.1%), and the average polyp size was 9.2 ± 2.8 mm. Delayed bleeding was identified from 1 to 5 days after resection (mean, 1.6 ± 1.2 days). The most common macroscopic type of polyp was a sessile polyp (10 cases, 55.6%), and histologic finding was a tubular adenoma in 13 cases (72.2%). Seventeen cases were treated with clipping for hemostasis and 1 case with epinephrine injection. Conclusion The right colon and a sessile polyp were associated with an increase in delayed postpolypectomy bleeding. Reducing risk factors and close observation were essential in high risk patients, and prompt management with hemoclips was effective.
Outcome of Early versus Delayed Evacuation of Spontaneous Lobar Hematomas in Unconscious Adults

ABSTRACT Objective: To explore the difference in outcomes of medium-sized lobar hematomas evacuated in early versus delayed fashion among unconscious noncomatose individuals. Methods: A retrospective analysis of demographic, clinical, and radiological data of unconscious patients admitted with lobar hematomas during 18 years was performed. Time to surgery was compared in various patient variables and characteristics. Outcome groups (favorable and poor) were also compared to find out any association with surgery timing, as well as potential indicators of outcome and mortality. Results: The mean follow-up period in this study was 7.5 months after discharge. Two-thirds of the patients carried favorable prognosis at final follow-up with mortality (7.3%) included among poor cases. Time to surgery was not associated to any of the patient characteristics, except for international normalized ratio and associated chest problems which represented the main indicators of delayed surgery. Rebleeding after evacuation was associated with shorter time to surgery in clots ≤35 cc but not in the whole group. Poor outcome was significantly associated with higher basal glucose levels, bigger hematomas, rebleeding after surgery, and delayed evacuation of clots ≤35 cc. The presence of mild intraventricular hemorrhage (IVH) per se was not associated with increased mortality or poor outcome; however, its volume was. Conclusion: Smaller lobar hematomas (≤35 cc) in unconscious adults (Glasgow Coma Scale 8–13) may be managed with initial conservative treatment, while larger hematomas (≤35 cc) are better evacuated as early as possible. Basal glucose levels and volume of mild IVH should be considered in the future management planes.
Innocent Women and Children: Gender, Norms and the Protection of Civilians

Innocent Women and Children: Gender, Norms and the Protection of Civilians. By R. Charli Carpenter. Burlington, VT: Ashgate, 2006. 230p. $89.95 cloth. On the occasion of Remembrance Day in grade six and as my classmates and I cut small poppies out of red construction paper, we learned about the brave young Canadian men who died fighting for our freedom and were laid to rest in Flanders Field. A striking memory of this history lesson was that I secretly congratulated myself for being a girl. If I ever found myself in the midst of a war, it was the boys who would have to fight. A narrow escape from a dreadful fate!
Reconceptualizing Media Literacy in the Social Studies: A Pragmatist Critique of the NCSS Position Statement on Media Literacy

Abstract The National Council for the Social Studies Position Statement on Media Literacy argues that media literacy can facilitate participatory democracy if students' interest in media is harnessed. The statement conceives of media technology as neutral and under-conceptualizes socializing aspects of media technologies that foster atomized individualism. Narrowly grounded in New Media Literacies, Critical Media Studies, and Medium Theory scholarship, it offers a limited understanding of media as merely conduits for message transmission and concludes that media technology will create a more democratic society if students are encouraged to participate in it. The authors' pragmatist reconceptualization examines media not only as transmission but also as a space where common meanings are constructed. The authors offer a critical review that advances an alternative direction for media literacy in which learning for participatory democracy includes analyzing not only medium, messages, and content but also media forms and their relations to transactional tendencies within the broader society.
Symbolic Interactionism Revisited: Potential Liabilities for the Self Constructed in the Crucible of Interpersonal Relationships.

The contributions are reviewed of three symbolic interactionists, Baldwin, Cooley, and Mead, for whom the self was primarily a social construction, crafted through the linguistic exchanges (i.e., symbolic interactions) with significant others. Al though the symbolic interactionists pointed to critical processes in the normative construction of the self, they did not alert us to the fact that self development dependent upon social interactions could go awry. Four potential liabilities of developing a self so dependent upon social processes are discussed: (a) the incor poration of unfavorable opinions about the self, (b) failure to internalize the opin ions of others, (c) conflict between socially-constructed multiple selves, and (d) the promotion of false-self behavior.
Success against the Odds

By drawing on comparative analyses of successful second-generation Turks from disadvantaged family backgrounds in France and the Netherlands, this article examines pathways and mechanisms that lead to educational success against the backdrop of structural and familial disadvantages. We foreground the experiences and practices of successful second-generation Turks in both countries and demonstrate the importance of institutional arrangements and their interactions with individual resources to account for their success. We use data from the “The Integration of the European Second Generation” (TIES) survey to reconstruct school careers and to inventory opportunities and constraints presented to them in the most important selection processes. We illustrate our findings with life stories drawn from qualitative interviews with TIES respondents in both settings. Combining the results of both quantitative and qualitative data analysis allows us to unravel the mechanisms of the educational success of second-generation Turks from disadvantaged backgrounds.
Using a Variety of Methods to Facilitate Redecisions

Redecision therapy has been fundamental to the authors' practice of psychotherapy since 1971. They describe using several methods to help patients accomplish redecisions and provide examples of well-known redecision methods as well as the use of Chaoyi Fanhuan Qigong (CFQ Healing Qigong), Emotional Freedom Technique, and Logosynthesis to facilitate redecisions.

Application of Computational Tools for Identification of miRNA and Their Target SNPs

MicroRNAs (miRNAs) are a class of small non-protein-coding RNAs that play important regulatory roles by targeting for cleavage or translational repression and involved in diverse biological functions. Accumulation of large amount of biological data indicates that miRNAs can function as tumor suppressors and oncogenes. Mutation, misexpression, and altered mature miRNA processing are implicated in carcinogenesis and tumor progression. Common single-nucleotide polymorphisms (SNPs) in miRNAs may change their property through altering miRNA expression and/or maturation, and thus they may have an effect on thousands of target mRNAs, resulting in diverse functional consequences. In this work we used computational tools to predict the functional role of mRNAs targeted by miRNA in colon cancer genes. We have presented a method which allows the use of PupaSuite, UTRscan and miRBase as a pipeline for the prediction of miRNA and their target, and evaluated the functional role of mRNA in colon cancer.
