Distributed RDFS Rules Reasoning for Large-Scaled RDF Graphs Using Spark

Scalable processing on large-scaled RDF graphs becomes a critical issue with the explosion of semantic web technologies. Most of the existing distributed RDF querying and reasoning solutions are designed based on the MapReduce paradigm. However, MapReduce should be further optimized since several inherent limitations such as lack of efficient job scheduling and iterative computing mechanisms affect its performance and flexibility. To overcome the drawbacks, some novel distributed programming models like Spark have been released and comprehensively used. To further improve the efficiency of RDFS rules reasoning for large-scaled RDF data, this paper design a graph-based RDF data partitioning and storage schema based on HBase. A novel RDFS reasoning approach is proposed by exploiting the Spark context. An experiment on the standard LUBM benchmark shows that our approach is more efficiency than existing solution.
Semantic Noise: Privacy-Protection of Nominal Microdata through Uncorrelated Noise Addition

Personal data are of great interest in statistical studies and to provide personalized services, but its release may impair the privacy of individuals. To protect the privacy, in this paper, we present the notion and practical enforcement of semantic noise, a semantically-grounded version of the numerical uncorrelated noise addition method, which is capable of masking textual data while properly preserving their semantics. Unlike other perturbative masking schemes, our method can work with both datasets containing information of several individuals and single data. Empirical results show that our proposal provides semantically-coherent outcomes preserving data utility better than non-semantic perturbative mechanisms.
On Highly Closed Cellular Algebras and Highly Closed Isomorphisms

We define and study $m$-closed cellular algebras (coherent configurations) and $m$-isomorphisms of cellular algebras which can be regarded as $m$th approximations of Schurian algebras (i.e. the centralizer algebras of permutation groups) and of strong isomorphisms (i.e. bijections of the point sets taking one algebra to the other) respectively. If $m=1$ we come to arbitrary cellular algebras and their weak isomorphisms (i.e. matrix algebra isomorphisms preserving the Hadamard multiplication). On the other hand, the algebras which are $m$-closed for all $m\ge 1$ are exactly Schurian ones whereas the weak isomorphisms which are $m$-isomorphisms for all $m\ge 1$ are exactly ones induced by strong isomorphisms. We show that for any $m$ there exist $m$-closed algebras on $O(m)$ points which are not Schurian and $m$-isomorphisms of cellular algebras on $O(m)$ points which are not induced by strong isomorphisms. This enables us to find for any $m$ an edge colored graph with $O(m)$ vertices satisfying the $m$-vertex condition and having non-Schurian adjacency algebra. On the other hand, we rediscover and explain from the algebraic point of view the Cai-Furer-Immerman phenomenon that the $m$-dimensional Weisfeiler-Lehman method fails to recognize the isomorphism of graphs in an efficient way.
Hepatic Mitochondrial Alterations and Increased Oxidative Stress in Nutritional Diabetes-Prone Psammomys obesus Model

Mitochondrial dysfunction is considered to be a pivotal component of insulin resistance and associated metabolic diseases. Psammomys obesus is a relevant model of nutritional diabetes since these adult animals exhibit a state of insulin resistance when fed a standard laboratory chow, hypercaloric for them as compared to their natural food. In this context, alterations in bioenergetics were studied. Using liver mitochondria isolated from these rats fed such a diet for 18 weeks, oxygen consumption rates, activities of respiratory complexes, and content in cytochromes were examined. Levels of malondialdehyde (MDA) and gluthatione (GSH) were measured in tissue homogenates. Diabetic Psammomys showed a serious liver deterioration (hepatic mass accretion, lipids accumulation), accompanied by an enhanced oxidative stress (MDA increased, GSH depleted). On the other hand, both ADP-dependent and uncoupled respirations greatly diminished below control values, and the respiratory flux to cytochrome oxydase was mildly lowered. Furthermore, an inhibition of complexes I and III together with an activation of complex II were found. With emergence of oxidative stress, possibly related to a defect in oxidative phosphorylation, some molecular adjustments could contribute to alleviate, at least in part, the deleterious outcomes of insulin resistance in this gerbil species.
Students' Knowledge and Beliefs concerning Environmental Issues in Four Countries

Abstract Five surveys conducted in the United States, Australia, England, and Israel on the knowledge and beliefs of ninth- and tenth-grade students on environmental issues could be compared because respondents answered similar questionnaires. Where investigated, sex and general achievement level were correlated with environmental knowledge. Students' beliefs tended to be stronger than their factual and conceptual knowledge. In Australia, England, and Israel, where students' sources of knowledge were also investigated, the mass media were the most important source. This influenced students' judgement on the seriousness of different environmental issues.
Performance supervision for multiple optical amplifiers in WDM transmission systems using spectral analysis

In this letter, we propose and experimentally demonstrate a novel supervisory scheme to monitor the working status of multiple optical amplifiers in a wavelength-division-multiplexing transmission link. An optical feedback loop with unique loop length is added around each inline optical amplifier to create monitoring signal at a common supervisory wavelength. By analyzing the RF spectra of the common supervisory wavelength at the receiver end, any failed optical amplifier in the transmission link can be identified.
A cheating detection framework for Unreal Tournament III: A machine learning approach

Cheating reportedly affects most of the multi-player online games and might easily jeopardize the game experience by providing an unfair competitive advantage to one player over the others. Accordingly, several efforts have been made in the past years to find reliable and scalable approaches to solve this problem. Unfortunately, cheating behaviors are rather difficult to detect and existing approaches generally require human supervision. In this work we introduce a novel framework to automatically detect cheating behaviors in Unreal Tournament III by exploiting supervised learning techniques. Our framework consists of three main components: (i) an extended game-server responsible for collecting the game data; (ii) a processing backend in charge of preprocessing data and detecting the cheating behaviors; (iii) an analysis frontend. We validated our framework with an experimental analysis which involved three human players, three game maps and five different supervised learning techniques, i.e., decision trees, Naive Bayes, random forest, neural networks, support vector machines. The results show that all the supervised learning techniques are able to classify correctly almost 90% of the test examples.
Effect of Archetypal Embeds on Feelings: An Indirect Route to Affecting Attitudes?

Abstract Advertising practitioners have long been the target of charges of unethical conduct stemming from their supposed use of subliminal techniques, though very few studies have shown any value of subliminal embeds in an advertising setting. One way advertising professionals can contend with such charges is to understand as much as possible about subliminal persuasion, including the situations, if any, in which it occurs. Many studies of subliminal persuasion have investigated the effect of subliminal stimuli on cognitive constructs. The authors add to that work by focusing on affect, specifically three types of feelings identified as important to advertising effectiveness: warm, upbeat, and negative feelings. They found empirical support for the hypothesis that unconscious processing of subliminal embeds has significant effects on the upbeat and negative feelings that subjects report in response to ads. Those feelings in turn had a significant influence on ad and brand attitudes, which suggests that s.
Fatal Cardiac Arrhythmia and Long-QT Syndrome in a New Form of Congenital Generalized Lipodystrophy with Muscle Rippling (CGL4) Due to PTRF-CAVIN Mutations

We investigated eight families with a novel subtype of congenital generalized lipodystrophy (CGL4) of whom five members had died from sudden cardiac death during their teenage years. ECG studies revealed features of long-QT syndrome, bradycardia, as well as supraventricular and ventricular tachycardias. Further symptoms comprised myopathy with muscle rippling, skeletal as well as smooth-muscle hypertrophy, leading to impaired gastrointestinal motility and hypertrophic pyloric stenosis in some children. Additionally, we found impaired bone formation with osteopenia, osteoporosis, and atlanto-axial instability. Homozygosity mapping located the gene within 2 Mbp on chromosome 17. Prioritization of 74 candidate genes with GeneDistiller for high expression in muscle and adipocytes suggested PTRF-CAVIN (Polymerase I and transcript release factor/Cavin) as the most probable candidate leading to the detection of homozygous mutations (c.160delG, c.362dupT). PTRF-CAVIN is essential for caveolae biogenesis. These cholesterol-rich plasmalemmal vesicles are involved in signal-transduction and vesicular trafficking and reside primarily on adipocytes, myocytes, and osteoblasts. Absence of PTRF-CAVIN did not influence abundance of its binding partner caveolin-1 and caveolin-3. In patient fibroblasts, however, caveolin-1 failed to localize toward the cell surface and electron microscopy revealed reduction of caveolae to less than 3%. Transfection of full-length PTRF-CAVIN reestablished the presence of caveolae. The loss of caveolae was confirmed by Atomic Force Microscopy (AFM) in combination with fluorescent imaging. PTRF-CAVIN deficiency thus presents the phenotypic spectrum caused by a quintessential lack of functional caveolae.
THE SINGLE PSYCHOLOGICAL TEST (OR TEST SYSTEM): MEASURING FOR HOPE

The thesis of this article is that the single psychological test or test system is a wholly inadequate decision‐aid to address the strategic problem‐objectives of the people aspect of business. After reviewing the current uses of the single test the article outlines the properties and tasks of psychological measurement. It proposes that only the joint use of several tests relevant to a specific problem objective can improve the accuracy of management decisions on people in the varied contexts of business.
ASSESSMENT OF HEMOGLOBIN BINDING PROTEIN IN LOGGERHEAD SEA TURTLES (CARETTA CARETTA) UNDERGOING REHABILITATION

Abstract: The acute phase response is an important component of the early reaction of the immune system to insults including infection, inflammation, trauma, neoplasia, and stress. Acute phase proteins are valuable prognostic indicators in many mammalian species but have been poorly studied in reptiles thus far. This study examined 18 paired samples from loggerhead sea turtles (Caretta caretta) for changes observed during the rehabilitation period. Analyses performed included packed cell volume (PCV), hemoglobin binding protein, and plasma protein electrophoresis. Significant differences were observed in all of the protein electrophoresis values. Notably, the concentration of hemoglobin binding protein (as determined by a haptoglobin assay) increased in conjunction with rising total protein (by refractometry) and PCV. The results indicate that this assay may have the potential to be a useful tool in assessing the health of sea turtles.
Additional vectors for PCR‐based gene tagging in Saccharomyces cerevisiae and Schizosaccharomyces pombe using nourseothricin resistance

The one‐step PCR‐mediated technique used for modification of chromosomal loci is a powerful tool for functional analysis in yeast. Both Saccharomyces cerevisiae and Schizosaccharomyces pombe are amenable to this technique. However, the scarce availability of selectable markers for Sz. pombe hampers the easy use of this technique in this species. Here, we describe the construction of new vectors deriving from the pFA6a family, which are suitable for tagging in both yeasts owing to the presence of a nourseothricin‐resistance cassette. These plasmids allow various gene manipulations at chromosomal loci, viz. N‐ and C‐terminal tagging with 3HA (haemagglutinin) or 13Myc epitopes, GST (glutathione S‐transferase), 4TAP (tandem affinity purification) and several GFP (green fluorescent protein) isoforms. For N‐terminal modifications, the use of different promoters allows constitutive (PADH1) or regulatable (PGAL1) promoters for S. cerevisiae and derivatives of Pnmt1 for Sz. pombe expression.

Cardiopulmonary responses to exercise in patients with hypertrophic cardiomyopathy

Objective To examine the submaximal and maximal indices of the exercise response of patients with hypertrophic cardiomyopathy. Design and setting Prospective examination of cardiopulmonary responses to ramp exercise test of a consecutive group of patients with hypertrophic cardiomyopathy attending a cardiomyopathy outpatient clinic. Methods 50 patients aged 12 to 76 years (mean (SD) 35 (14)) with diagnosis of hypertrophic cardiomyopathy performed incremental cycle ergometry; 22 sedentary volunteers (seven female, 15 male) aged 14 to 58 years (mean (SD) 31 (12)) served as controls. Respiratory gas was continuously sampled from the mouthpiece, and its concentration profile phase aligned to the respired air flow signals. Following analogue to digital conversion, gas exchange variables were computed breath by breath and the data were averaged every 30 seconds for graphic display. A 12 lead ECG was monitored continuously and recorded every three minutes during the exercise. Results Both the peak oxygen uptake attained on the test (V˙o 2 peak) and anaerobic threshold were reduced in patients with hypertrophic cardiomyopathy compared with the control group (p < 0.0001). In 29 patients (59%) theV˙o 2 peak was less than 60% and only two patients achieved a peak above 80% of their predicted values. The anaerobic threshold was below 60% of the predicted value in 31 patients and above 80% in only three patients. The slope of oxygen uptake/work rate relation (ΔV˙o 2/ΔWR) was decreased in 16 patients (32%). The maximum oxygen pulse (V˙o 2/HR) was reduced as a percentage of the predicted value, and became flat at high work rates in 32 patients. There was a significant correlation between anaerobic threshold andV˙o 2 peak (p < 0.0001), work efficiency (p < 0.0001), and maximum oxygen pulse (p < 0.0001). The slope of change in ventilation against change in carbon dioxide output (ΔV˙e/ΔV˙co 2) for the subanaerobic threshold range was increased in 36 patients (72%) and was inversely correlated with anaerobic threshold (p < 0.0002). Conclusions There were severe abnormalities in maximal and submaximal indices of pulmonary gas exchange in a cohort of hypertrophic cardiomyopathy patients attending a referral cardiovascular clinic. The pattern of the abnormalities suggests that a reduced stroke volume response, ventilation/perfusion mismatch, and abnormal peripheral oxygen utilisation are the possible mechanisms of exercise intolerance.
Low Prevalence of Heterogeneous Vancomycin-Intermediate Staphylococcus aureus Isolates among Connecticut Veterans

ABSTRACT The Etest glycopeptide resistance detection identified two potential heterogeneous vancomycin-intermediate Staphylococcus aureus (hVISA) isolates from a screen of 288 methicillin-resistant Staphylococcus aureus (MRSA) isolates from patients at a Connecticut Veterans Hospital. However, the two isolates did not meet the criteria for hVISA by the population analysis profile-area under the curve analysis, arguing against routine screening for hVISA in this low prevalence population.
Methodological approaches at PhD and skills sought for research posts in academia: a mismatch?

There is a concern in the UK about a lack of research methods skills among social researchers, especially in relation to quantitative methods. This article draws on findings of a study exploring the training needs of social scientists across the lifespan in the UK and focuses on the research training needs identified by PhD students and the research skills sought by academic employers. The data reported comprises a survey of PhD students, a survey of directors of research centres/holders of large grants and a content analysis of social science research posts. The findings indicate that students in several social science disciplines have a preference for qualitative methods in their PhDs while academic employers and job vacancies for academic posts indicate a need for researchers with skills in quantitative methods. The findings have important implications for training and supervision of research students and identify a need to narrow the gap between early‐career researchers’ skills and employers’ needs.

Antibody response to a T-dependent antigen requires B cell expression of complement receptors

Several lines of evidence indicate that antibody responses to T- dependent antigens require complement receptors expressed on either B lymphocytes or follicular dendritic cells. We have used RAG-2 deficient blastocyst complementation to create mice specifically lacking B cell complement receptors. Despite normal expression of complement receptor 1 (CR1[CD35]) and CR2 (CD21) on follicular dendritic cells, these mice have a profound defect in their capacity to mount a T-dependent antibody response. This is the first direct demonstration in vivo that B cell expression of complement receptors is required for a humoral immune response. This is the first direct demonstration in vivo that B cell expression of complement receptors is required for a humoral immune response. This suggests that CD21 and/or CD35 on B lymphocytes may be required for cellular activation, adsorptive endocytosis of antigen, recruitment to germinal centers, and/or protection from apoptosis during the humoral response to T-dependent antigens.
The Problem with Boys: Bridewealth Accumulation, Sibling Gender, and the Propensity to Participate in Cattle Raiding among the Kuria of Tanzania

Although a fair amount has been written on the subject of African “crime” in general (e.g., Read 1964, Brillon 1985, Austen 1986, Cohen 1986, Crummey 1986) and East African livestock theft in particular (e.g., Fukui and Turton 1979, Anderson 1986, Hendrickson, Mearns, and Armon 1996), scant effort has been made to establish who, in a sociological sense, these “criminals” are (but see Moore 1975 and Heald 1986 for two noteworthy exceptions). This article endeavors to contribute to this effort using field data collected among the agro-pastoral Kuria of Tarime District in northern Tanzania. Among the Kuria, whose population straddles the border between Tanzania and Kenya, many young men are actively engaged in an illict livestock trade in which cattle stolen in Tanzania—mainly from other Kuria but also from neighboring peoples—are sold to buyers, mainly butchers, inside Tanzania or else run across the border for cash sale in Kenya. Kuria cattle raiding is by no means a new phenomenon, but it has undergone a profound transformation in the course of the past century—from its precolonial roles of demonstrating the mettle of new warriors and enlarging the community cattle herd to an illict, often quite violent cash-marketoriented enterprise—in response to the pressures exerted by the colonial economy, capitalist penetration, and the policies of the postcolonial Tanzanian state (Fleisher 2000a, b). Fleisher (1999) has already demonstrated that, among the Kuria, cattle theft is overwhelmingly the “occupa-
