SEMANTIC APPROACH UTILIZING DATA MINING AND CASE-BASED REASONING FOR IT SUPPORT SERVICE

Information Technology (IT) plays a very important role in all organizations. IT executives are constantly faced with problems that are difficult to tackle. Failure in IT service can interrupt the functioning of an organization. Case-Based Reasoning (CBR) is a problem solving methodology where experience in the form of past cases can be used to solve problems, thereby assisting the automation of problem solving and experience management. Furthermore, the performance, quality and efficiency of CBR systems can be enhanced through data mining. In order to support the IT team for faster and efficient problem resolution, a case-based reasoning approach integrated with data mining techniques could be utilized. In this paper, the study done on various CBR systems and data mining techniques for problem and experience management is explained. A system is proposed for IT experience and problem management with semantic retrieval in order to increase the efficiency and quality of the IT support service.
Interprofessional education: A nurse practitioner impacts family medicine residents' smoking cessation counselling experiences

This qualitative research paper describes a successful example of interprofessional education with family medicine residents (FMR) by a nurse practitioner (NP) colleague. The educational impact of the NP role in regard to smoking cessation counselling is revealed by the analysis of 16 semi-structured interviews using a phenomenological approach. The key themes depicted the NP as an educator and mentor, encourager and referral resource. Outcomes of improved knowledge, skills, and motivation towards providing smoking cessation counselling are described. This research provides some understanding of how professional students’ learning and practice can be affected by a member of another profession through direct and indirect approaches. The experiences identified how interprofessional education and collaborative clinical practice can affect FMRs’ attitudes, knowledge and behaviours. This learning can guide us in enhancing the quality of education provided to all health care professionals.
Cooperative Spectrum Sensing for Cognitive Radio

With today’s increase in the usage of wireless devices and the consequent spectrum allocation, radio spectrum is becoming scarce. However studies have shown that most of the allotted spectrum is not used for large periods of time. Cognitive radio has been proposed to exploit the presence of these spectrum holes. Spectrum sensing which is one of the most important operations of cognitive radio, determines the efficiency with which the secondary users can use the primary spectrum, without causing appreciable interference to the primary users. Several factors like fading and shadowing affect the ability of the cognitive radio to detect the primary user. Previous work has shown that cooperation among the cognitive users can increase the detection probability for a given probability of false alarm. The aim of our project is to develop a spectrum sensing scheme for cognitive radio based on a model that is realistic and takes into account all the factors that would affect the system in practice. In this work, we first investigate the effect of variable channel gain on the cooperation between secondary users, as an extension of [13]. Then we go on to propose a linear cooperation based spectrum sensing scheme for OFDM based cognitive users using the energy detector method. The results of the simulations, done based on the analytical results, are then presented which show the extent of advantage cooperation between the secondary radios and the effect of the channel gain between the secondary user and the fusion centre. Finally we outline the future extensions on this work.
Media Consumption, Perceptions of Crime Risk and Fear of Crime: Examining Race/Ethnic Differences

This study compares the impact of multiple forms of crime-related media across white, Latino, and African American respondents on their perception of crime risk in their neighborhoods and fear of crime, using a state-wide survey of 3,712 Californians. The findings indicate some difference in the impact of crime-related media by different media forms and across race/ethnic groups. Consumption of local television news significantly elevated perceptions of risk and fear of crime for all groups. Crime-based reality programs produced equivalent fear, but the effects of newspaper and crime drama consumption were more variable. Realistic television content about crime was most influential on viewers' perceptions of and responses to crime than fictional accounts or newspapers.
Flow diversion with Pipeline Embolic Device as treatment of subarachnoid hemorrhage secondary to blister aneurysms: dual-center experience and review of the literature

Background Aneurysmal subarachnoid hemorrhage (aSAH) secondary to blister-type aneurysms (BAs) is associated with high morbidity and mortality. Microsurgical clipping or wrapping and/or use of traditional endovascular techniques to repair the lesion result in frequent regrowth and rebleeds and ultimately high fatality rates. Because of the purely endoluminal nature of arterial reconstruction, flow diversion may represent an ideal option to repair ruptured BAs. Methods We performed a retrospective analysis of our database including all consecutive patients with aSAH secondary to BAs treated with the Pipeline Embolic Device (PED) between November 2013 and November 2015 in two institutions. We collected basic patient demographics, aneurysm size, location, number and sizes of PEDs used, use of coiling, 30-day modified Rankin Scale (mRS) score, and follow-up imaging data. Results Ten cases of aSAH were found as a result of a ruptured BA. Patients had a mean age of 47.2 years (range 27–68). Mean Hunt and Hess score was 1.6 (range 1–4). Lesions were predominantly left-sided, mostly along the dorsal aspect of the internal carotid artery, either paraclinoid or paraophthalmic (8/10). In two patients the BA was located in the left middle cerebral artery. All lesions were very small (mean 1.4×1.5 mm; range 0.75–2.1 mm). Placement of a single PED resulted in immediate occlusion or near-occlusion of the BA in 9 out of 10 patients. Nine patients did very well; eight had a 90-day mRS score of 0 and one had a 90-day mRS score of 1. Follow-up digital subtraction angiography was performed in all patients (mean 15 months; range 7–24). In the surviving nine patients there was complete occlusion of the BA on long-term follow-up angiography. Conclusions Repair of ruptured BA with PED may be a safe and durable option.
Measurement of Regional Myocardial Blood Flow With Multiple Colored Microspheres*

BackgroundThe use of radioactive microspheres (RM) for the measurement of regional myocardial blood flow (RMBF) is limited and inaccessible to many investigators due to radiation safety concerns and radioactive waste disposal problems. Therefore, a new method for the measurement of RMBF using colored microspheres (CM) was developed. Methods and ResultsPolystyrene spheres (diameter, 15 ± 0.1 [SD] gm; density, 1.09 g/ml) were dyed with one of five colors. With the injection ofCM into the left atrium or into a coronary perfusion line, RMBF and its distribution can be determined. CM are extracted from the myocardium and blood by digestion with potassium hydroxide and subsequent microfiltration. The dyes are then recovered from the CM within a defined volume of a solvent, and their concentrations are determined by spectrophotometry. The separation of composite absorbance spectra by spectrophotometry with the CM technique was as good as the separation of energy spectra by a -ycounter using the RM technique. Leaching of dye from the CM was less than 0.1% during a 2-month period in vitro. Significant leaching of dye from the microspheres also did not occur during 8 hours in the blood and myocardium of four anesthetized dogs in vivo. For further validation of this method, pairs of CM and RM (15.5 ± 0.1 [SD] μm) were simultaneously injected under five different RMBF conditions (range, 0-10 ml/[min.g]) into the left anterior descending coronary artery of four anesthetized pigs, with coronary inflow as a flow reference, or into the left atrium of four anesthetized dogs using aortic blood withdrawal as a reference. The relation between RMBF determined by CM and RM was CM = 0.01 + 1.00 RM (r = 0.98, n = 1,080 data points) in the pigs, and CM=−0.19 + 0.92* RM (r = 0.97, n = 1,813 data points) in the dogs. ConclusionsMeasurement of RMBF with CM yields values very similar to those of RM. Their use is less expensive and avoids all the disadvantages related to radioactivity, thus offering an alternative method for as many as five RMBF measurements in a single experiment.

Semantic Similarity tailored on the Application Context

The paper proposes an approach to assess the semantic similarity among instances of an ontology. It aims to define a sensitive measurement of semantic similarity, which takes into account different hints hidden in the ontology definition and explicitly considers the application context. The similarity measurement is computed by analyzing, combining and extending some of the existing similarity measures and tailoring them according to the criteria induced by specific application context.
Distinction of clenbuterol intake from drug or contaminated food of animal origin in a controlled administration trial – the potential of enantiomeric separation for doping control analysis

ABSTRACT The differentiation of clenbuterol abuse and unintentional ingestion from contaminated meat is crucial with respect to the valuation of an adverse analytical finding in human sports doping control. The proportion of the two enantiomers of clenbuterol may serve as potential discriminating parameter. For the determination of the individual enantiomers, specific methods were developed and validated for the different matrices under investigation based on chiral chromatography coupled to tandem mass spectrometry. Data are presented from the administration to humans of clenbuterol from a pharmaceutical preparation, and from cattle meat and liver containing residues. A shift in the proportion of the enantiomers in cattle meat is detected and this signature is also found in human urine after ingestion. Thus, an altered enantiomeric composition of clenbuterol may be used to substantiate athletes’ claims following adverse analytical findings in doping control. However, in meat, the enantiomeric composition was found to be highly variable. Species as well as tissue dependent variances need to be considered in interpreting enantiomer discrimination. Analysis of post administration urines from a controlled experiment comparing the administration of racemic clenbuterol from a registered pharmaceutical preparation and the administration of residue-containing meat and liver (nonracemic mixture) from treated animals is reported. Furthermore doping control samples from Mexican U17 World Championship 2011 of the Fédération Internationale de Football Association (FIFA), with adverse analytical findings for clenbuterol, were re-analysed.

Una aproximación desde la teoría de la legitimidad a la información medioambiental revelada por las empresas españolas cotizadas

Recientes estudios han revelado que es dificil llegar a una conclusion fiable del comportamiento medioambiental de las firmas espanolas analizando la informacion que emiten en sus estados financieros [Larrinaga y otros, 2002; Llena y otros, 2007 ]. Por esta razon, investigar los motivos que empujan a estas entidades a informar sobre su impacto medioambiental se ha convertido en una cuestion relevante. La presente investigacion se aproximo a este complejo fenomeno con ayuda de la teoria de la legitimidad y la metodologia de analisis de contenido.Tras analizar la informacion medioambiental revelada en los estados financieros por las empresas que durante los anos 1997, 1998 y 1999 cotizaron en el mercado continuo y la bolsa de Madrid los resultados son compatibles con las siguientes aseveraciones: las empresas emiten informacion medioambiental para influir en la percepcion que la sociedad tiene de ellas; la informacion esta fuertemente sesgada hacia los intereses de las empresas; y la actual legislacion espanola es incapaz de resolver este problema. Recent studies have shown that it is difficult to reach a reliable conclusion of the environmental behavior of Spanish firms that issue by analyzing the information in its financial statements [Larrinaga and others, 2002; Fill et al 2007]. Therefore, to investigate the reasons that drive these organizations to report on their environmental impact has become an important issue. This research approached this complex phenomenon using the theory of legitimacy and contenido.Tras analysis methodology to analyze the environmental information disclosed in the financial statements by companies during 1997, 1998 and 1999 quoted in continuous market and the Bombay Stock Exchange the results are compatible with the following statements: companies issue environmental information to influence the perception that society has of them; information is heavily biased towards business interests; and the current Spanish legislation can not solve this problem.
Multilabel user classification using the community structure of online networks

We study the problem of semi-supervised, multi-label user classification of networked data in the online social platform setting. We propose a framework that combines unsupervised community extraction and supervised, community-based feature weighting before training a classifier. We introduce Approximate Regularized Commute-Time Embedding (ARCTE), an algorithm that projects the users of a social graph onto a latent space, but instead of packing the global structure into a matrix of predefined rank, as many spectral and neural representation learning methods do, it extracts local communities for all users in the graph in order to learn a sparse embedding. To this end, we employ an improvement of personalized PageRank algorithms for searching locally in each user’s graph structure. Then, we perform supervised community feature weighting in order to boost the importance of highly predictive communities. We assess our method performance on the problem of user classification by performing an extensive comparative study among various recent methods based on graph embeddings. The comparison shows that ARCTE significantly outperforms the competition in almost all cases, achieving up to 35% relative improvement compared to the second best competing method in terms of F1-score.
Why do the failure rates decrease

It is quite plausible that any device or system reliability shows an increasing failure rate (IFR) as age, use or both may cause it to wear out over time. Nevertheless, explaining a decreasing failure rate, which means an improvement as time goes by, is far from intuitive. Mixtures of lifetime distributions turn out to be the most widespread explanation for this "positive ageing". In this work, the proportional hazard rate (PHR) is revisited and related to an exponential mixture. We also analyse the effect of mixing on the patterns of dependence on time that the mixture exhibits.
Image annotation refinement using semantic similarity correlation

Automatic image annotation is a promising way to achieve more effective image management and retrieval by using keywords. However, system performances of the existing state-of-the-art keyword annotation schemes are often not so satisfactory. Therefore, image annotation refinement is crucial to improve the imprecise annotation results. In this paper, a novel approach is developed to automatically refine the initial annotation of images. First, for a query image, the candidate annotations are obtained by a step-up model-based algorithm using perceptual visual characteristic. Then, a refine algorithm, fast random walk with restart is used to re-rank the candidate annotations and the top ones are reserved as the final annotations. Experiments conducted on the typical Corel dataset shows that the proposed scheme can effectively improve the automatic annotation performance.
Neurovascular Coupling and Decoupling in the Cortex during Voluntary Locomotion

Hemodynamic signals are widely used to infer neural activity in the brain. We tested the hypothesis that hemodynamic signals faithfully report neural activity during voluntary behaviors by measuring cerebral blood volume (CBV) and neural activity in the somatosensory cortex and frontal cortex of head-fixed mice during locomotion. Locomotion induced a large and robust increase in firing rate and gamma-band (40–100 Hz) power in the local field potential in the limb representations in somatosensory cortex, and was accompanied by increases in CBV, demonstrating that hemodynamic signals are coupled with neural activity in this region. However, in the frontal cortex, CBV did not change during locomotion, but firing rate and gamma-band power both increased, indicating a decoupling of neural activity from the hemodynamic signal. These results show that hemodynamic signals are not faithful indicators of the mean neural activity in the frontal cortex during locomotion; thus, the results from fMRI and other hemodynamic imaging methodologies for studying neural processes must be interpreted with caution.
Pro-Natalism and Hygienism in France, 1900-1940. The Example of the Fight against Venereal Disease

How are the criteria of quantity and quality combined in population policies? The fight against "social scourges" in France between 1900 and 1940 is a very interesting case in point, revealing the complexity of the arguments deployed in population policies. Among these scourges, the fight against venereal disease represents an extreme case linked to the representations of sexually transmitted infections. Shameful and therefore unmentionable, these diseases were rarely exposed to public attention, despite concern about depopulation. The questions of population quality and quantity became crystallized around the productivity of marriage. A network of physicians thus took it upon themselves to educate the population about venereal diseases and their adverse effects on the population and the family. The content of this propaganda, notably the anti-venereal films, leaves not doubt as to the role of pro-natalism in health education.
An Ecosystemic and Socio-Technical View on Software Maintenance and Evolution

In this invited paper I focus on the difficulties of maintaining and evolving software systems that are part of a larger ecosystem. While not every software system falls under this category, software ecosystems are becoming ubiquitous due to the omnipresence of open source software. I present several challenges that arise during maintenance and evolution of software ecosystems, and I argue how some of these challenges should be addressed by adopting a socio-technical view and by relying on a multidisciplinary and mixed methods research approach. My arguments are accompanied by an extensive, though unavoidably incomplete, set of references to the state-of-the-art research in this domain.
Bis[4-(dimethylamino)pyridinium] tetrabromidodiphenylstannate(IV)

The SnIV atom of the stannate anion in the title salt, (C7H11N2)2[SnBr4(C6H5)2], lies on a center of inversion in a tetragonally compressed octahedron. The two independent Br atoms in the anion are hydrogen-bond acceptors for the same cation.
Measuring educational opportunity as perceived by students: A process indicator

This paper introduces the idea of the perceived curriculum from the student's viewpoint. Based on this, students' perception of opportunity to learn is measured and a process indicator developed for use in school effectiveness research and school evaluation. The Essential Skills of the New Zealand Curriculum are used as the foundation for the development of an instrument to measure opportunity to learn. The instrument measures students' perceptions of opportunity to learn from activities within the school environment. Some illustrative results from a baseline study of 1,300 pupils from 20 schools are presented. Potential uses for an instrument are proposed.
Seasonal Succession Leads to Habitat-Dependent Differentiation in Ribosomal RNA:DNA Ratios among Freshwater Lake Bacteria

Relative abundance profiles of bacterial populations measured by sequencing DNA or RNA of marker genes can widely differ. These differences, made apparent when calculating ribosomal RNA:DNA ratios, have been interpreted as variable activities of bacterial populations. However, inconsistent correlations between ribosomal RNA:DNA ratios and metabolic activity or growth rates have led to a more conservative interpretation of this metric as the cellular protein synthesis potential (PSP). Little is known, particularly in freshwater systems, about how PSP varies for specific taxa across temporal and spatial environmental gradients and how conserved PSP is across bacterial phylogeny. Here, we generated 16S rRNA gene sequencing data using simultaneously extracted DNA and RNA from fractionated (free-living and particulate) water samples taken seasonally along a eutrophic freshwater estuary to oligotrophic pelagic transect in Lake Michigan. In contrast to previous reports, we observed frequent clustering of DNA and RNA data from the same sample. Analysis of the overlap in taxa detected at the RNA and DNA level indicated that microbial dormancy may be more common in the estuary, the particulate fraction, and during the stratified period. Across spatiotemporal gradients, PSP was often conserved at the phylum and class levels. PSPs for specific taxa were more similar across habitats in spring than in summer and fall. This was most notable for PSPs of the same taxa when located in the free-living or particulate fractions, but also when contrasting surface to deep, and estuary to Lake Michigan communities. Our results show that community composition assessed by RNA and DNA measurements are more similar than previously assumed in freshwater systems. However, the similarity between RNA and DNA measurements and taxa-specific PSPs that drive community-level similarities are conditional on spatiotemporal factors.
Late bilinguals see a scan in scanner AND in scandal: dissecting formal overlap from morphological priming in the processing of derived words

Masked priming research with late (non-native) bilinguals has reported facilitation effects following morphologically derived prime words (scanner – scan). However, unlike for native speakers, there are suggestions that purely orthographic prime-target overlap (scandal – scan) also produces priming in non-native visual word recognition. Our study directly compares orthographically related and derived prime-target pairs. While native readers showed morphological but not formal overlap priming, the two prime types yielded the same magnitudes of facilitation for non-natives. We argue that early word recognition processes in a non-native language are more influenced by surface-form properties than in one's native language.
Unfalsified direct adaptive control of a two-link robot arm

This paper describes an application of unfalsified control theory to the design of an adaptive controller for a nonlinear robot manipulator. A nonlinear "computed torque" control structure is employed. Four parameters representing unknown masses, inertias and other dynamical coefficients are adaptively adjusted in real-time using an linear programming technique to optimally satisfy control-law unfalsification condition. Simulations show that the method yields significantly more precise and rapid parameter adjustments than conventional continuous parameter update rules, especially when the manipulator arm is subject to sudden random changes in mass or load properties.
