The Role of Technologies, Behaviors, Gender, and Gender Stereotype Traits in Adolescents’ Cyber Aggression

The present study focused on the impact of gender and gender stereotype traits (i.e., masculinity, femininity) on cyber aggression perpetration utilizing different technologies (i.e., social-networking sites, gaming consoles, mobile phones) and behaviors (i.e., cyber relational aggression, cyber verbal aggression, hacking). Participants included 233 eighth graders (108 female; Mage = 13.26, SD = 0.36) from two middle schools in the Midwestern United States. Adolescents completed questionnaires on their endorsement of masculinity and femininity traits as well as how often they engaged in cyber aggression perpetration (i.e., cyber relational aggression, cyber verbal aggression, hacking) through mobile phones, social-networking sites, and gaming consoles. Findings indicated that boys and girls with more feminine traits engaged in more cyber relational aggression through social-networking sites and mobile phones, while boys and girls who endorsed more masculine traits perpetrated this behavior and cyber verbal aggression more often through online gaming. In addition, these boys and girls engaged in more hacking through all technologies when compared with girls and boys who reported more feminine traits. Results of this study indicate the importance of delineating gender stereotype traits, behaviors, and technologies when examining cyber aggression perpetration.
Fecal calprotectin and C-reactive protein are associated with positive findings in capsule endoscopy in suspected small bowel Crohn's disease.

BACKGROUND AND AIM Capsule endoscopy is an extended tool for the diagnosis of small bowel Crohn's disease. However, factors associated with positive findings of this technique have not been well established. Our aim is to asses which factors are associated with a better diagnostic yield of capsule endoscopy in suspected small bowel Crohn's disease. MATERIAL AND METHODS This was a retrospective study including patients under capsule endoscopy because of suspected small bowel Crohn's disease. Demographic data of these patients, as well as symptoms and laboratory data including hemoglobin levels, count of leucocytes and platelets, and levels of C-reactive protein, erythrocyte sedimentation rate and fecal calprotectin were collected. Capsule endoscopy studies were classified as negative (no lesions) or positive (lesions suggestive of Crohn's disease). Descriptive, univariate and multivariate analysis were done, as well as diagnostic yield tests of the different markers for predicting lesions in capsule studies. RESULTS One hundred and twenty-four patients were included (85 women and 39 men). The average age was 38.21 years. Levels of C-reactive protein and fecal calprotectin were the markers more frequently associated with positive findings in capsule endoscopy. Calprotectin presented the best sensitivity as isolated marker. The association of altered levels of C-reactive protein and calprotectin showed the best specificity and predictive values. CONCLUSIONS C-reactive protein and fecal calprotectin are appropriate biomarkers for selecting patients with suspected Crohn's disease of the small bowel for capsule endoscopy studies.
The Semantic Structure of Animal Terms: A Developmental Study

This study explored the role of semantic structure within the domain of animal terms in children's and adults' spontaneous operations on these terms. Twenty-four subjects at each of six educational levels were given four tasks. Freelisting of animal terms and animal associations to animal words showed similar semantic structures across all educational levels, including doctoral students in zoology, with a few strongly associated terms, and a large group of fairly isolated terms. Sorting of animal terms and ratings of animal pair dissimilarities yielded a dominant dimension of size for grades seven, eleven, and undergraduate groups. The dominant dimension for zoologists, however, was based on food habits. The implications of these results for the development of semantic structures are discussed.
A latent semantic indexing based method for solving multiple instance learning problem in region-based image retrieval

Relevance feedback (RF) is a widely used technique in incorporating user's knowledge with the learning process for content-based image retrieval (CBIR). As a supervised learning technique, it has been shown to significantly increase the retrieval accuracy. However, as a CBIR system continues to receive user queries and user feedbacks, the information of user preferences across query sessions are often lost at the end of search, thus requiring the feedback process to be restarted for each new query. A few works targeting long-term learning have been done in general CBIR domain to alleviate this problem. However, none of them address the needs and long-term similarity learning techniques for region-based image retrieval. This paper proposes a latent semantic indexing (LSI) based method to utilize users' relevance feedback information. The proposed region-based image retrieval system is constructed on a multiple instance learning (MIL) framework with one-class support vector machine (SVM) as its core. Experiments show that the proposed method can better utilize users' feedbacks of previous sessions, thus improving the performance of the learning algorithm (one-class SVM).
Communication in the management of uncertainty: The case of persons living with HIV or AIDS

Communication is a means of managing uncertainty. In a state of uncertainty: (a) information seeking can reduce uncertainty by allowing for better discrimination between or among alternatives; (b) information seeking can increase uncertainty by increasing the number of alternatives, or by blurring the distinction between or among alternatives; and (c) information avoidance can maintain uncertainty. Individuals living with HIV or AIDS, like many other chronically‐ill or terminally‐ill individuals, must manage high levels of uncertainty about their illness. Participants in a focus group study of persons with HIV or AIDS reported effective uncertainty management, including managing uncertainty that was challenging, managing uncertainty that was essential for maintaining hope, learning to live with chronic uncertainty, and managing information problems. New information can serve uncertainty management even if it fails to reduce the number or ambiguity of alternatives, because new information can invite a reappraisal of uncertainty. A theory of uncertainty management based on these findings is offered.
Shallow Water Acoustic Channel Modeling Based on Analytical Second Order Statistics for Moving Transmitter/Receiver

Underwater acoustic channels are among the most challenging communication media. Time-varying multipath fading, long delay spread, significant Doppler spread, and frequency-dependent path loss are the main aspects of such channels. In this paper we present a statistical shallow water channel model for moving transmitter/receiver based on analytical second order statistics. To do so, we first propose a channel impulse response (CIR) model that captures most of the physical properties of shallow waters. Then we find the probability density function (PDF) of the angle of arrival (AoA) for paths with different number of surface and bottom reflections. To find closed form expressions for the second order statistics of the CIR, we approximate the PDFs of AoA with half-circular Rice PDF: a novel PDF introduced in this work. By mathematical tractability of this new PDF, analytical statistics including autocorrelation function, scattering function, and time-frequency correlation function are derived. The results are compared with experimental findings for verification.
Differences in the biological phenotype of low-yielding (L) and high-yielding (H) variants of swine influenza virus A/NJ/11/76 are associated with their different receptor-binding activity.

Low- (L) and high-yielding (H) variants of A/sw/NJ/11/76 influenza virus were compared for their growth properties in embryonated chicken eggs and MDCK cells and for their binding affinity for the membrane fractions prepared from cells of the chicken embryo allantoic membrane. MDCK, and swine tracheal cells, as well as for soluble sialic acid containing macromolecules and monovalent sialosides. We have shown, that during infection in MDCK cells and in eggs, the progeny of the L variant remain predominantly cell associated, in contrast to those of H. As a result, accumulation of the L mutant in allantoic or culture fluid is significantly slowed in comparison with the H variant. Visualization of the infectious foci formed by the viruses in MDCK cell monolayers and on the allantoic membrane revealed that L spreads predominantly from cell to cell, while the spread of H involves release of the virus progeny into solution and its rapid distribution over the cell monolayer via convectional flow of the liquid. In the binding assays, L displayed significantly higher binding affinity than H for cellular membranes, gangliosides, and sialylglycoproteins, however, the affinity of the variants for the monovalent sialic acid compounds was comparable. Unlike H. L bound strongly to dextran sulfate. The data obtained suggest that all distinctions of the L and H biological phenotypes reported previously [Kilbourne, E.D. , Taylor, A. H. Whitaker, C.W. , Sahai, R. , and Caton, A (1988) Hemagglutinin polymorphism as the basis for low-and high-yield phenotypes of swine influenza virus. Proc. Natl. Acad. Sci. USA 85, 7782-7785] could be rationally explained by a more avid binding of the L variant to the surface of target cells, and that this effect is mainly due to enhanced electrostatic interactions.
Psychological Counseling needs and Academic achievement of students at the Secondary level

Psychological counselling that helps to attend to the social emotional needs of the school students which goes a long way in removing obstacles of learning. It is thus, an integral part of education. The present study has investigated the level of psychological counselling needs and academic achievement of students. Survey method was used to carry out the investigation for a sample of students at the secondary level. The study examined the relationship between psychological counselling needs of students and their academic achievement. The sample consisted of 300 secondary school students. Psychological Counselling Needs Scale (Chouhan and Arora, 2009) was used to assess the psychological counselling needs of students and the academic achievement marks scored by students in their half yearly examination were taken. The results of the analyses showed that school psychological counselling needs has significant influence on academic achievement. A significant difference was found between psychological counselling needs and academic achievement of secondary students studying in government, government-aided and private schools. Findings also revealed a significant positive correlation between psychological counselling needs and academic achievement. Keywords: Psychological Counselling Needs, Academic Achievement
L2 AND DEAF LEARNERS’ KNOWLEDGE OF NUMERICALLY QUANTIFIED ENGLISH SENTENCES

This study assessed knowledge of numerically quantified English sentences in two learner populations—second language (L2) learners and deaf learners—whose acquisition of English occurs under conditions of restricted access to the target language input. Under the experimental test conditions, interlanguage parallels were predicted to arise from acquisitional pressures imposed by derivational economy on universal grammar (UG)–guided semantic interpretation. The results of a task in which participants matched sentences to multiple discourse depictions confirmed the predicted parallels. However, in matching underinformative sentences to depicted contexts, the L2 and deaf learner groups overactivated discourse-pragmatic knowledge. The restriction of indefinite noun phrases to singleton indefinites and the cancellation of scalar implicatures rendered sentences more informative in underinformative contexts, producing incorrect—although principled—interpretations. These results inform English acquisition at the interface of semantics and discourse pragmatics and provide further support that economy pressures yield L2 learner and deaf learner interlanguage parallels as observed, for instance, in learners’ interpretative knowledge of universally quantified English sentences.
aVR ST elevation: an important but neglected sign in ST elevation acute myocardial infarction.

AIM This study evaluated the prognostic implications of aVR ST elevation during ST elevation acute myocardial infarction (AMI). METHODS AND RESULTS The Hirulog and Early Reperfusion/Occlusion-2 study randomized 17 073 patients with acute ST elevation AMI within 6 h of symptom onset to receive either bivalirudin or heparin, in addition to streptokinase and aspirin. The treatments had no effect on the primary endpoint of 30-day mortality. Electrocardiographic recordings were performed at randomization and at 60 min after commencing streptokinase. aVR ST elevation > or =1 mm was associated with higher 30-day mortality in 15 315 patients with normal intraventricular conduction regardless of AMI location (14.7% vs. 11.2% for anterior AMI, P = 0.0045 and 16.0% vs. 6.4% for inferior AMI, P < 0.0001). After adjusting for summed ST elevation and ST depression in other leads, associations with higher mortality were found with aVR ST elevation of > or =1.5 mm for anterior [odds ratio 1.69 (95% CI 1.16 to 2.45)] and of > or =1 mm for inferior AMI [odds ratio 2.41 (95% CI 1.76 to 3.30)]. There was a significant interaction between aVR ST elevation and infarct location. Thirty-day mortality was similar with anterior and inferior AMI when aVR ST elevation was present (11.5% vs. 13.2%, respectively, P = 0.51 with 1 mm and 23.5% vs. 22.5% respectively, P = 0.84 with > or = 1.5 mm ST elevation). After fibrinolytic therapy, resolution of ST elevation in aVR to <1 mm was associated with lower mortality, while new ST elevation > or =1 mm was associated with higher mortality. CONCLUSION aVR ST elevation is an important adverse prognostic sign in AMI.
‘What Difference does it Make? Women's Pop Cultural Production and Consumption in Manchester’

This paper explores the experiences of women in small cultural businesses and is based upon interviews with women working in a range of contexts in Manchester's popular music sector. The research seeks to promote wider consideration of women's roles in cultural production and consumption. We argue that it is necessary that experiences of production and consumption be understood as inter-related processes. Each part of this process is imbued with particular gender characteristics that can serve to reinforce existing patterns and hierarchies. We explore the ways in which female leisure and consumption patterns have been marginalised and how this in turn shapes cultural production. This process influences career choices but it is also reinforced through the integration of consumption into the cultural workplace. Practices often associated with the sector, such as the blurring of work and leisure and ‘networking’, appear to be understood and operated in significantly different ways by women. As cultural industries such as popular music are predicated upon the colonisation of urban space we explore the use of the city and the particular character of Manchester's music scene. We conclude that, despite the existence of highly contingent and individualised identities, significant gender power relations remain evident. These are particularly clear in discussion of the performative and sexualised aspects of the job.
Excitation-Transcription Coupling via Calcium/Calmodulin-dependent Protein Kinase/ERK1/2 Signaling Mediates the Coordinate Induction of VGLUT2 and Narp Triggered by a Prolonged Increase in Glutamatergic Synaptic Activity*

Homeostatic scaling of glutamatergic and GABAergic transmission is triggered by prolonged alterations in synaptic neuronal activity. We have previously described a presynaptic mechanism for synaptic homeostasis and plasticity that involves scaling the level of vesicular glutamate (VGLUT1) and γ-aminobutyric acid (GABA) (VGAT) transporter biosynthesis. These molecular determinants of vesicle filling and quantal size are regulated by neuronal activity in an opposite manner and bi-directionally. Here, we report that a striking induction of VGLUT2 mRNA and synaptic protein is triggered by a prolonged increase in glutamatergic synaptic activity in mature neocortical neuronal networks in vitro together with two determinants of inhibitory synaptic strength, the neuronal activity-regulated pentraxin (Narp), and glutamate decarboxylase (GAD65). Activity-dependent induction of VGLUT2 and Narp exhibits a similar intermediate-early gene response that is blocked by actinomycin D and tetrodotoxin, by inhibitors of ionotropic glutamate receptors and L-type voltage-gated calcium channels, and is dependent on downstream signaling via calmodulin, calcium/calmodulin-dependent protein kinase (CaMK) and extracellular signal-regulated kinase 1/2 (ERK1/2). The co-induction of VGLUT2 and Narp triggered by prolonged γ-aminobutyric acid type A receptor blockade is independent of brain-derived nerve growth factor and TrkB receptor signaling. VGLUT2 protein induction occurs on a subset of cortically derived synaptic vesicles in excitatory synapses on somata and dendritic processes of multipolar GABAergic interneurons, recognized sites for the clustering of α-amino-3-hydroxy-5-methyl-4-isoxazolepropionate glutamate receptors by Narp. We propose that VGLUT2 and Narp induction by excitation-transcription coupling leads to increased glutamatergic transmission at synapses on GABAergic inhibitory feedback neurons as part of a coordinated program of Ca2+-signal transcription involved in mechanisms of homeostatic plasticity after prolonged hyperactivity.
Using Prayer and Other Forms of Positive Mental Energy in Direct Practice: An Evidence-Based Perspective

Practitioners receive little guidance regarding the use of spiritual interventions such as intercessory prayer during their graduate educational programs. Yet—for better or worse—a surprisingly high percentage of social workers appear to pray verbally with, and/or silently for, their clients. Drawing from an evidence-based perspective, this article attempts to determine (1) if prayer and other forms of positive mental energy should be used in practice settings and (2) if informed consent should be obtained prior to engaging in silent prayer for clients. The evidence suggests, respectively, an equivocal answer and a tentative negative. For practitioners that believe the present research supports the use of prayer, guidelines are provided to help ensure that the practice is conducted in an ethical manner that safeguards client autonomy.
Laser in situ keratomileusis and photorefractive keratectomy for residual refractive error after phakic intraocular lens implantation.

PURPOSE To determine the visual and refractive outcome of photorefractive keratectomy (PRK) and laser in situ keratomileusis (LASIK) in eyes with prior posterior chamber phakic intraocular lens implantation for high myopia. METHODS We studied a series of 37 consecutive eyes of 31 patients who underwent LASIK or PRK for residual refractive error following collamer posterior chamber intraocular lens (IOL) (Staar Surgical Implantable Contact Lens) implantation into a phakic eye. Twenty-eight eyes had LASIK and nine eyes had PRK. Mean follow-up was 8.1 +/- 4.7 months after laser ablation (range, 3 to 18 mo). RESULTS The preoperative mean spherical equivalent refraction prior to phakic posterior chamber IOL implantation was -17.74 +/- 4.89 D (range, -9.75 to -28.00 D). Following phakic IOL implantation and prior to LASIK or PRK, mean spherical equivalent refraction was -2.56 +/- 2.34 D (range, -0.25 to -8.75 D). One month following LASIK or PRK, mean spherical equivalent refraction was -0.24 +/- 0.52 D (range, -1.50 to +1.50 D), 3 months following LASIK or PRK, mean spherical equivalent refraction was -0.19 +/- 0.50 D (range, -1.50 to +1.00 D). The refraction was within +/-1.00 D of emmetropia in 36 eyes (97.2%) and within +/-0.50 D in 31 eyes (83.7%). Three eyes developed anterior subcapsular opacities several weeks after laser ablation, one eye developed macular hemorrhage 4 weeks after laser ablation, and one eye had corticosteroid induced ocular hypertension. CONCLUSIONS LASIK or PRK can be used to treat the residual refractive error following posterior chamber phakic IOL implantation.
Learning of Ontologies from the Web: the Analysis of Existent Approaches

The next generation of the Web, called Semantic Web, has to improve the Web with semantic (ontological) page annotations to enable knowledge-level querying and searches. Manual construction of these ontologies will require tremendous efforts that force future integration of machine learning with knowledge acquisition to enable highly automated ontology learning. In the paper we present the state of the-art in the field of ontology learning from the Web to see how it can contribute to the task of semantic Web querying. We consider three components of the query processing system: natural language ontologies, domain ontologies and ontology instances. We discuss the requirements for machine learning algorithms to be applied for the learning of the ontologies of each type from the Web documents, and survey the existent ontology learning and other closely related approaches.
An Earley-type recognizer for dependency grammar

The paper is a first attempt to fill a gap in the dependency literature, by providing a mathematical result on the complexity of recognition with a dependency grammar. The paper describes an improved Earley-type recognizer with a complexity O(IGI2n3). The improvement is due to a precompilation of the dependency rules into parse tables, that determine the conditions of applicability of two primary actions, predict and scan, used in recognition.
A Thousand Pardons: The Effectiveness of Verbal Remedial Tactics during Account Episodes

This experimental study examined the effects of accounts, 'offender' and 'victim/witness' sex, and sex-role orientation on rating scales and 'behaviouroid' and behavioural measures. Participants who spent up to 45 minutes completing questionnaires that proved unusable due to a confederate's error were exposed to one of four systematically varied accounts or explanations. Account type, participant and confederate sex, and participant sex-role orientation served as predictor variables. In general, concessions and excuses yielded more positive impressions, greater commitment on the part of participant victims to help the offender, and greater help than did refusals, but the effectiveness of accounts also depended on by whom they were proffered. Results demonstrated partial support for politeness theory predictions.
Escolhas institucionais e transição por transação: sistemas políticos de Brasil e Espanha em perspectiva comparada

The objective of this article is to compare the performance of the political systems in Brazil and Spain. In both countries the redemocratization process occurred by way of negotiation with the leaders of the out-going authoritarian regimes. The hypothesis emerging from these two experiences is that this transition format limited the range of possible institutional choices. An analysis of three fundamental dimensions in these choices, the electoral and party systems in each country, the systems of government that were adopted, and the internal organization of the respective Legislative Branches indicates that the history of transition fostered a concentration of decision-making power in the hands of the Administration and the party leadership. Thus, despite important differences in the Constitutional dimension of the respective political systems, Brazil and Spain shaped similar procedural rules that have led to a huge public policy-making advantage for the Administration.
