Detection of cyberbullying on social media messages in Turkish

The increased use of the Internet and the ease of access to online communities like social media have provided an avenue for cybercrimes. Cyberbullying, which is a kind of cybercrime, is defined as an aggressive, intentional action against a defenseless person by using the Internet, social media, or other electronic contents. Researchers have found that many of the bullying cases have tragically ended in suicides; hence automatic detection of cyberbullying has become important. The aim of this study is to detect cyberbullying on social media messages written in Turkish. To our knowledge, this is the first study which makes cyberbully detection on Turkish texts. We prepare a dataset from Instagram and Twitter messages written in Turkish and then we applied machine learning techniques that are Support Vector Machines (SVM), decision tree (C4.5), Naïve Bayes Multinomial, and k Nearest Neighbors (kNN) classifiers to detect cyberbullying. We also apply information gain and chi-square feature selection methods to improve the accuracy of classifiers. We observe that when both words and emoticons in the text messages are taken into account as features, cyberbully detection improves. Among the classifiers, Naïve Bayes Multinomial is the most successful one in terms both classification accuracy and running time. When feature selection is applied classification accuracy improves up to 84% for the dataset used.
THE DEVELOPMENT AND APPLICATION OF A REFINED METHOD FOR ESTIMATING GENE FLOW FROM ANGIOSPERM PATERNITY ANALYSIS

While gene flow is an important factor determining the genetic structure of populations, there are few studies that quantify it empirically. Paternity‐exclusion analysis has recently been employed to assess the number of seeds fathered by individuals from outside of a study population (gene flow by pollen), but appropriate estimation procedures have been limited to special cases. In this report, we illustrate a general Monte Carlo method that provides an approximate maximum‐likelihood estimate of gene flow by pollen from paternity‐exclusion analysis. We also show that the method can be used to estimate the number of foreign gametes received by individuals in the study population.
The behaviour and self-esteem of children with specific speech and language difficulties.

BACKGROUND Children with specific speech and language difficulties (SSLD) may have associated difficulties that impair their access to the curriculum, and their social relationships at home and in school. AIMS (i) To identify the range of additional problems experienced by children with SSLD in different educational contexts; (ii) to consider the relationship between these problems and the child's current language status and (iii) to consider the child's self-esteem and the extent to which self-esteem is associated with the primary language problem or other associated difficulties. SAMPLE Sixty-nine children (17 girls, 52 boys) aged 7-8 years (Year 3) who had been identified as having SSLD, 59 from two local education authorities and 10 from regional special schools for children with severe speech and language difficulties. METHOD The children were assessed on a range of cognitive, language and educational measures; children and teachers completed a measure of the children's self-esteem (Pictorial Scale of Perceived Competence and Social Acceptance); teachers and parents completed a behavioural questionnaire (Strengths and Difficulties Questionnaire (SDQ); teachers also completed a further rating scale which included a behaviour subscale (Junior Rating Scale: JRS). RESULTS The children's behaviour was rated as significantly different from the norm on both the SDQ and JRS, with the parents more likely to rate the child as having problems, but also as having prosocial behaviour. Both teachers and parents tended to rate the boys as having more problems than girls on the SDQ, with significant differences for the parents' ratings occurring on the total score and the hyperactivity and conduct problems scales. The children had positive self perceptions, which were comparable to the standardisation sample, and generally significantly higher than those of the teachers. The language and educational attainment scores of the children in special and mainstream schools were generally not significantly different, but parents rated the latter group as having more behaviour difficulties. Multiple regression analyses identified language comprehension and reading comprehension as the only predictors of the parents' rating of behaviour (on the SDQ). No relationship was found with the teachers' ratings. CONCLUSIONS Behavioural difficulties, but not low self-esteem, are common in children of 7-8 years with SSLD, but the differences in patterns of relationship between parents and teachers, and with respect to children attending mainstream and special schools, challenge simple interpretations of comorbidity.
A high-performance self-clocked digital-output quartz gyroscope

High-performance electro-static gyroscopes require expensive vacuum-packaging, to maintain the high-Q of the MEMS, and may require high actuation voltages. Piezo sensors, on the other hand, do not suffer from these shortcomings. In this work, the architecture and the measurements results of a high-performance quartz gyro are presented. The architecture of the gyroscope interface ASIC adopts a mostly-digital implementation, where the drive-loop processing, demodulation, and post-filtering are implemented in the digital domain. Furthermore, the ASIC clock is based on self-clocking scheme, where the gyro drive frequency drives all internal clocks. The digital implementation, combined with self-clocking, allows the read-out ASIC to interface to different quartz-gyro sensing elements, with a wide range of drive-frequencies. The ASIC is tested with a tuning fork quartz gyro sensing element. The complete gyro sensor module achieves a ±500 deg/s input range, and a noise-floor of 2.5 mdeg/s/√Hz.
Decreased expression of C3b receptor (CR1) on erythrocytes of patients with systemic lupus erythematosus contrasts with its normal expression in other systemic diseases and does not correlate with the occurrence or severity of SLE nephritis.

Expression of the C3b/C4b receptor (CR1) on erythrocytes is decreased in patients with systemic lupus erythematosus (SLE) compared to normal individuals, and the CR1 antigen is absent from podocytes in severe diffuse proliferate nephritis of SLE. In the present study, we examined the relationship between the number of CR1 on erythrocytes and the occurrence and severity of SLE nephritis, and assessed the expression of CR1 on erythrocytes and the occurrence and severity of SLE nephritis, and assessed the expression of CR1 on erythrocytes in non-SLE nephritis and other systemic inflammatory diseases by measuring the binding of 125I-labeled rabbit F(ab')2 and murine monoclonal IgG anti-CR1 antibodies to erythrocytes of normal individuals and patients in a French population. The number of binding sites for monoclonal anti-CR1 antibody on erythrocytes of 116 normal individuals was 743 +/- 22 (mean +/- SEM) with a range of 169-1,333, and the frequency distribution of this number in the population was bimodal. In 112 patients with SLE, the mean number of CR1 sites on erythrocytes was decreased to 62% of the mean for normal individuals (p less than 0.001). No correlation was found between CR1 expression on erythrocytes and the presence or immunohistopathological type of glomerulonephritis in biopsy specimens from these patients. The mean number of CR1 on erythrocytes of 29 patients with non-SLE glomerulonephritis was slightly decreased to 89% of the normal mean (p greater than 0.05), which could not be attributed to glomerular immune complex disease or vasculitis.

The Effects of Health Insurance Parity Laws for Substance Use Disorder Treatment on Traffic Fatalities: Evidence of Unintended Benefits

Each year, 10,000 individuals die in alcohol-impaired traffic accidents in the United States, while psychoactive drugs are involved in 20% of all fatal traffic accidents. We investigate whether state parity laws for substance use disorder (SUD) treatment have the unintended benefit of reducing fatal traffic accidents. Parity laws compel insurers to cover SUD treatment in private insurance markets, thereby reducing the financial costs of and increasing access to treatment for beneficiaries. We employ over 20 years of administrative data from the national Fatal Accident Reporting System coupled with a differences-in-differences research design to investigate the potential spillover effects of parity laws to traffic safety. Our findings indicate that passage of a state parity law reduces fatal traffic accident rates by 4.1 to 5.4%. These findings suggest that government regulations requiring insurers to cover SUD treatment can significantly improve traffic safety, possibly by reducing the number of impaired drivers on roadways.
Evidence that glucose is the major transferred metabolite in dinoflagellate–cnidarian symbiosis

SUMMARY Reef-building corals and many other cnidarians are symbiotic with dinoflagellates of the genus Symbiodinium. It has long been known that the endosymbiotic algae transfer much of their photosynthetically fixed carbon to the host and that this can provide much of the host's total energy. However, it has remained unclear which metabolite(s) are directly translocated from the algae into the host tissue. We reexamined this question in the small sea anemone Aiptasia using labeling of intact animals in the light with 13C-bicarbonate, rapid homogenization and separation of animal and algal fractions, and analysis of metabolite labeling by gas chromatography-mass spectrometry. We found labeled glucose in the animal fraction within 2 min of exposure to 13C-bicarbonate, whereas no significant labeling of other compounds was observed within the first 10 min. Although considerable previous evidence has suggested that glycerol might be a major translocated metabolite, we saw no significant labeling of glycerol within the first hour, and incubation of intact animals with 13C-labeled glycerol did not result in a rapid production of 13C-glucose. In contrast, when Symbiodinium cells freshly isolated from host tissue were exposed to light and 13C-bicarbonate in the presence of host homogenate, labeled glycerol, but not glucose, was detected in the medium. We also observed early production of labeled glucose, but not glycerol, in three coral species. Taken together, the results suggest that glucose is the major translocated metabolite in dinoflagellate–cnidarian symbiosis and that the release of glycerol from isolated algae may be part of a stress response.
Adjuvant Chemotherapy for Non-small Cell Lung Cancer: Practice Patterns and Outcomes in the General Population of Ontario, Canada

Background: Adjuvant chemotherapy (ACT) is known to improve survival in patients with early-stage non-small cell lung cancer. Herein, we describe chemotherapy regimens used, dose modifications, survival, and treatment-related toxicity in the general population. Methods: All cases of non-small cell lung cancer diagnosed in Ontario in the period 2004–2006 who underwent surgical resection (n = 3354) were identified using the Ontario Cancer Registry in this population-based retrospective cohort study. We linked electronic records of treatment to the registry to identify all cases treated with ACT (n = 1032) and describe drugs, regimens, and dosages delivered. As a proxy measure of ACT-related toxicity, we evaluated deaths and hospitalizations within 16 weeks of starting ACT. Factors associated with dose modification were evaluated by logistic regression. The Cox proportional hazards model was used to describe associations between patient-, disease-, and treatment-related factors and survival. Results: ACT regimens were identified for 584 of 1032 ACT cases. Almost all cases included cisplatin- or carboplatin-based regimens (478/584, 82%, and 99/584, 17%, respectively). The most common regimen was a vinroelbine/cisplatin doublet (412/584, 71%); 64% of these cases had a dose reduction or omission. Dose modification was not associated with inferior survival on multivariate analysis. Twelve percent of all ACT cases were admitted to hospital within 16 weeks of starting ACT, and there was a 1.6% death rate potentially attributable to ACT. Survival of all ACT cases was comparable with outcomes reported in clinical trials. Conclusions: ACT regimens used, toxicity, and survival outcomes in the general population are comparable with those reported in clinical trials. Dose modifications used in clinical practice are not associated with inferior survival.
Mechanisms of granuloma formation in murine Mycobacterium avium infection: the contribution of CD4+ T cells.

Infection with the virulent Mycobacterium avium strain TMC 724 caused progressive infection in C57BL/6 and BALB/c mice, while infection with a less virulent strain (M. avium SE 01) resulted in chronically persistent bacterial loads. Livers of mice infected with TMC 724 were characterized by progressively expanding tumor-like infiltrations of epithelioid macrophages, while SE 01 induced well-developed, compact epithelioid granulomas that remained constant in size and number for at least 4 months. When C57BL/6 mice were depleted of CD4+ T cells by i.p. administration of specific mAb at the time of infection, their capacity to initiate granuloma formation was completely abrogated during the first 4 weeks of infection. Semi-quantitative competitive RT-PCR of liver homogenates obtained 3 weeks after infection revealed that depletion of CD4+ T cells was accompanied by a 25-fold reduced expression of IFN-gamma mRNA and a 5-fold reduced expression of tumor necrosis factor (TNF)-alpha mRNA when compared to control infected mice. Granuloma morphology in response to either TMC 724 or SE 01 was similar in immunodeficient SCID mice to that observed in syngeneic BALB/c mice. However, SCID mice developed granulomas in a delayed fashion and were less efficient in surrounding infected Kupffer cells with an inflammatory infiltration. The delayed kinetics of granuloma initiation in infected SCID mice was paralleled by a lower mRNA expression for IFN-gamma and TNF-alpha compared to that observed in infected BALB/c mice. mAb-mediated neutralization of IFN-gamma in BALB/c mice significantly reduced inflammatory infiltrations and granuloma formation. These data support the conclusion that CD4+ T cells accelerate granuloma formation by enhancing the production of TNF-alpha and IFN-gamma at the site of infection.
Characteristics of the spread of apple proliferation by its vector Cacopsylla picta.

The distribution and natural phytoplasma infection of Cacopsylla picta were investigated during a long-term field survey between 2002 and 2009 in commercial and abandoned apple proliferation-infected orchards throughout Germany, northern Switzerland, and eastern France. Comparable population dynamics were described for the different sites whereas considerable variations in the absolute population densities were observed among the years. Individual polymerase chain reaction (PCR) testing revealed, for each year, a rather stable natural infection rate with ? Candidatus Phytoplasma mali? of ? 10% for overwintered adults of C. picta. Both genders were equally highly infected although more females were caught. The overall male/female ratio was 1:1.5. No direct correlation was found between the infection status of the orchard and the infection rate of overwintered C. picta. No influence of agricultural practices was seen. However, a relationship between the incidence of the disease and the vector population density became evident on a regional scale. Successful transmission of ? Ca. P. mali? occurred each year with overwintered individuals as well as with new adults. The transmission efficiency varied among the years within 8 to 45% for overwintered adults and 2 to 20% for individuals of the new generation. The load of single C. picta with ? Ca. P. mali? was determined by quantitative real-time PCR. High phytoplasma titers were measured in overwintered adults already at their first appearance in the orchards after remigration from their overwintering hosts. Thus, the data indicate the transmission of the disease on a regional scale by remigrant adults of C. picta and at a local scale within the same season by emigrant adults which developed on infected plants.
Fibronectin matrix assembly enhances adhesion-dependent cell growth.

Cell growth control in non-transformed cells depends, in part, on adhesive interactions with the extracellular matrix. Following injury, excess or altered fibronectin deposition into the extracellular matrix may contribute to the pathogenesis of fibrosis and atherosclerosis by triggering changes in specific cell functions associated with wound repair, including cell proliferation and migration. To assess the role of fibronectin polymerization on cell growth, we isolated mouse embryonic cells that lack endogenous fibronectin (fibronectin-null cells) and established them in culture under serum-free conditions. These fibronectin-null cells do not produce any detectable fibronectin, but are capable of assembling a fibronectin matrix when cultured in the presence of exogenously added fibronectin. Our data indicate that adhesion-dependent growth in fibronectin-null cells is dramatically increased (>2-5x) by culturing cells in the presence of fibronectin. This fibronectin-induced cell growth was blocked by inhibiting fibronectin matrix assembly. Arg-Gly-Asp peptides or fragments of fibronectin that contain the Arg-Gly-Asp cell binding site promoted clustering of the (&agr ;)5beta1 integrin in focal adhesions, but did not enhance cell growth. These data indicate that the polymerization of fibronectin into the extracellular matrix positively regulates cell growth, and that occupancy and clustering of fibronectin-binding integrins alone are not sufficient to trigger increased cell growth.
Asynchronous design of networks-on-chip

The Network-on-chip concept has evolved as a solution to a broad range of problems related to the design of complex systems-on-chip (SoC) with tenths or hundreds of (heterogeneous) IP-cores. The paper introduces the NoC concept, identifies a range of possible timing organizations (globally-synchronous, mesochronous, globally-asynchronous locally-synchronous and fully asynchronous), discusses the circuitry needed to implement these timing methodologies, and provides some implementation details for a couple of asynchronous NoCs designed at the Technical University of Denmark (DTU). The paper is written to support an invited talk at the NORCHIP'2007 conference.
Ambient Networks - A Framework for Multi-Access Control in Heterogeneous Networks

In the ambient networks project research is ongoing in order to define a new control space for future internetworking. This internetworking will be characterized by a high degree of network heterogeneity as well as nomadicity and mobility of both users as well as networks. The so called ambient control space (ACS), provides functionality to support how to manage these traits of future internetworking. This paper provides a short presentation on the architecture of ambient networks and the ACS, and then focus on how connectivity is handled from a multi-access and mobility perspective through the support of the ACS.
Evaluation of Seasonal Feeding Patterns of West Nile Virus Vectors in Bernalillo County, New Mexico, United States: Implications for Disease Transmission

ABSTRACT Many mosquito species take bloodmeals predominantly from either birds or mammals. Other mosquito species are less host-specific and feed readily on both. Furthermore, some species tend to alter their feeding patterns over the course of the year; early in the mosquito season such species may feed primarily on a particular host type, and subsequently take an increasingly larger proportion of their bloodmeals from an alternative host type as the season progresses. We have examined the feeding patterns of the three mosquito species found in Bernalillo County, NM: Culex quinquefasciatus (Say), Culex tarsalis (Coquillett), and Aedes vexons (Meigen). Specifically, we seek to determine if any of these species displays a seasonal shift in terms of its host utilization pattern. Our analysis focuses on these three species because they are all considered to be competent vectors for the West Nile virus ( WNV). Our current data for Cx. quinquefasciatus suggest that unlike elsewhere in its range, this species increases its proportion of avian bloodmeals as the season progresses. Alternatively, Ae. vexans feeds primarily on mammals, whereas Cx. tarsalis appears to feed on both mammals and birds throughout the mosquito season. A more complete understanding of the feeding habits of these three mosquito species may help to clarify the transmission dynamics of WNV in Bernalillo County.
Recruited inflammatory cells mediate endotoxin-induced lung maturation in preterm fetal lambs.

RATIONALE Chorioamnionitis is paradoxically associated with a decreased incidence of respiratory distress syndrome in preterm infants. In preterm lambs, intraamniotic endotoxin and interleukin 1 (IL-1) induce lung inflammation followed by lung maturation. OBJECTIVE To test if inflammatory cells are required to mediate induced lung maturation. METHODS Lung inflammation was induced by intraamniotic injection of endotoxin or IL-1. Inflammatory cell recruitment to the lung was inhibited by an anti-CD18 blocking antibody given intramuscularly to the fetus. Preterm lambs were delivered at 124-d gestation (term = 150 d) 2 or 7 d after exposure to endotoxin/IL-1 or endotoxin/IL-1 + anti-CD18 antibody. MEASUREMENTS Lung inflammation was measured by bronchoalveolar lavage fluid cell count, inflammatory scoring of lung parenchyma, and expression of proinflammatory cytokines and inducible nitric oxide synthase. Lung maturation was quantitated by surfactant protein mRNA expression, saturated phosphatidylcholine pool size, and pressure-volume curves. MAIN RESULTS Inhibition of CD18 significantly reduced endotoxin-induced but not IL-1-induced fetal lung inflammatory cell recruitment and activation as well as expression of proinflammatory cytokines. Compared with control lungs, both endotoxin and IL-1 induced lung maturation. Anti-CD18 antibody administration inhibited only endotoxin-induced but not IL-1-induced increases in surfactant protein mRNA and surfactant saturated phosphatidylcholine. Exposure to anti-CD18 antibody moderated endotoxin-induced increases in lung volumes but had no effect on IL-1-induced increases in lung volumes. CONCLUSIONS (1) Endotoxin- but not IL-1-induced inflammatory cell recruitment in the preterm fetal lamb lung is CD18 dependent; (2) recruited inflammatory cells mediate some aspects of fetal lung maturation.
Tuning of electroreceptors in the blind cave salamander, Proteus anguinus L.

The blind cave salamander's (Proteus anguinus L.) sensitivity for electrical fields was determined by recordings from afferent fibers coming from ampullary electroreceptors. The animals were stimulated with single rectangular or continuous sinusoidal electrical signals passed through the cave water in the experimental tank. Best threshold sensitivities of the fibers for both kinds of signals were in the same range (0.1-0.5 mV/cm = 30-150 nA/cm2). The fibers showed phase-locked responses to rostrally cathodic phases of rectangular or sinusoidal stimuli and suppression to anodal phases. Units were tuned to 'best frequencies' (B.F., sine waves) between 20 and 40 Hz. Any functional, i.e. phase-related, firing or suppression of firing occurs in a total frequency range of less than 0.1 to around 100 Hz. This frequency range of tuning in the primary fibers was the same as found in the behavior, and this therefore reflects the peripheral sensory properties. Electrical sensitivity might be of special value for these cave dwelling animals, as they may detect and recognize prey animals by means of the prey's electrical field spreading into the surroundings, i.e. its electromyogram.
