A Comparative Analysis of the Revised Children's Manifest Anxiety Scale Scores of Traumatized Youth With and Without PTSD Relative to Non-Traumatized Controls

This study compared the Revised Children's Manifest Anxiety Scale (RCMAS) scores of traumatized youth with or without PTSD to the scores of a nonclinical comparison group. Child diagnostic interviews identified children with PTSD (28), traumatized children without PTSD (63), and a nonclinical comparison group (41). In the absence of major comorbid disorders, children with PTSD had significantly higher RCMAS total scores and significantly higher scores on the RCMAS Physiological Anxiety, Worry/Oversensitivity, and Social Concern/Concentration subscales. Nonsignificant differences were observed between groups on the RCMAS Lie subscale. The RCMAS scores of the traumatized PTSD negatives and controls did not significantly differ. Implications for research and practice are considered.
Targeted Lipid Analysis of Haemolytic Mycelial Extracts of Aspergillus niger

Ethanolic extracts of mycelia from Aspergillus niger (strain N402) grown in liquid media were observed to have haemolytic activity on bovine erythrocytes. This haemolytic activity decreased significantly during the time of growth (1–3 days). Moreover, when A. niger was grown on carbon-deprived medium, the efficiency of this haemolytic activity in the ethanolic extracts was much lower than when grown in carbon-enriched medium, and became almost undetectable after 3 days of growth in carbon-deprived medium. The lipid composition of these ethanolic extracts was analysed by liquid chromatography–electrospray ionisation tandem mass spectrometry. This haemolytic activity can be mainly linked to the relative levels of the molar ratios of the unsaturated fatty acids and lysophosphatidylcholines.
A PC-based cephalometric analysis system

Cephalograms are clinically useful for cephalometric diagnosis and superimposition. The measurements for cephalometry has always been done manually in practice. We have developed a cephalometric analysis system which can be used to improve the measurements by computer software. The software was developed as a multi-document interface (MDI) application under the environment of Microsoft Windows. Two kinds of image, cephalograms and tracing papers, are supported. Three modules were included: (1) the automatic landmarking module locates landmarks on the digitized cephalograms; (2) the manual landmarking module provides a function manual to locate the landmarks on the screen through an interactive user interface; and (3) the cephalometric analysis module calculates the measurements. In our experience, it has been shown the system turns out to be a handy tool for orthodontists in diagnosis and treatment.
An efficient technique for Multikeyword based Search and Retrieval of cloud data

Enormous amount of outsource information are stored and retrieved across the global. During that process some difficulties are raised to maintain security while providing retrieval and searching procedures. Due to security concerns, sensitive data is protected by encryption before moving to the cloud. Normally precise information retrieval is difficult over encrypted cloud data. To overcome these issues, we propose an Enhanced Multikeyword Top-k Search and Retrieval (EMTR) scheme; it achieves good accuracy and high efficiency. First, the document can be efficiently estimated using inverted indexing. Then the user could query by any number of queried keywords appearing in the document which evaluate the relevance scoring of the document and to the search query to retrieve relevant information from cloud storage. Furthermore, we establish a new ranking procedure to retrieve highest ranked documents (i.e., most relevant) in the data set that brings considerable speedup over inverted weighted indexing. Our analysis demonstrates that the proposed scheme achieve high accuracy, improved search quality and efficient data retrieval with high speed.
Endogenous nitric oxide and myocardial adaptation to ischemia.

Ischemic myocardium does not inevitably undergo necrosis but rather can survive through downregulation of contractile function, ie, "hibernate. " To study the role of endogenous NO in this adaptation, 41 enflurane-anesthetized swine were subjected to 90 minutes of moderate left anterior descending coronary artery hypoperfusion and assigned to placebo (P), to 30 mg/kg N(G)-nitro-L-arginine (L-NNA) IV to inhibit NO synthase, or to aortic constriction (AO) to match the increased left ventricular pressure observed with L-NNA. During normoperfusion, a regional myocardial external work index (WI, mm Hg. mm, sonomicrometry and micromanometry) was reduced with L-NNA (from 326+/-27 [SEM] to 250+/-19, P<0.05) but increased with AO (from 321+/-16 to 363+/-19, P<0.05 versus L-NNA). At 10 minutes of ischemia, WI was lower with L-NNA (109+/-10, P<0.05) than P (180+/-22) and AO (170+/-11) and did not change further at 85 minutes of ischemia. Relationships between WI and transmural myocardial blood flow and oxygen consumption were shifted rightward by L-NNA versus P and AO at both 10 and 85 minutes of ischemia. The maximal increment in calcium-activated external work was not different during normoperfusion among groups but was decreased during ischemia with L-NNA. L-NNA transiently increased myocardial contractile calcium sensitivity along with systemic pressure but reduced it during ongoing ischemia. The free-energy change of ATP hydrolysis after an early ischemic decrease recovered toward baseline values in all groups, and necrosis was absent after 2 (triphenyltetrazolium chloride staining) or 8 (histology) hours of reperfusion. Thus, endogenous NO contributes to hibernation by reducing oxygen consumption and preserving calcium sensitivity and contractile function without an energy cost during ischemia.
Globalization and new ELT challenges in China

AS ECONOMICS and trade turn the world into “a global village”, English is playing an increasingly important role in China as a lingua franca for such matters as business, information, international travel, the Internet, cultural entertainment, and the environment, all of which have brought great changes in every aspect of our lives. Native English speakers are regarded as linguistically privileged, but such non-native English-speakers as the Chinese, in order to overcome their disadvantage, are launching campaigns to enable themselves to use English more accurately and fluently. ‘Communicative competence’ has become the chief goal of English language learning and teaching. This essay seeks to analyse the great changes that are taking place educationally in China, especially in ELT, emphasizing the importance of communicative language teaching (CLT), teacher training, reform of the examination system, and raising people's awareness of new challenges in education and life.
The Fallacy of Composition of Oblivious RAM and Searchable Encryption

Oblivious RAM (ORAM) is a tool proposed to hide access pattern leakage, and there has been a lot of progress in the efficiency of ORAM schemes; however, less attention has been paid to study the applicability of ORAM for cloud applications such as symmetric searchable encryption (SSE). Although, searchable encryption is one of the motivations for ORAM research, no in-depth study of the applicability of ORAM to searchable encryption exists as of June 2015. In this work, we initiate the formal study of using ORAM to reduce the access pattern leakage in searchable encryption. We propose four new leakage classes and develop a systematic methodology to study the applicability of ORAM to SSE. We develop a worst-case communication baseline for SSE. We show that completely eliminating leakage in SSE is impossible. We propose single keyword schemes for our leakage classes and show that either they perform worse than streaming the entire outsourced data (for a large fraction of queries) or they do not provide meaningful reduction in leakage. We present detailed evaluation using the Enron email corpus and the complete English Wikipedia corpus.
The use of CD47-modified biomaterials to mitigate the immune response

Addressing the aberrant interactions between immune cells and biomaterials represents an unmet need in biomaterial research. Although progress has been made in the development of bioinert coatings, identifying and targeting relevant cellular and molecular pathways can provide additional therapeutic strategies to address this major healthcare concern. To that end, we describe the immune inhibitory motif, receptor–ligand pairing of signal regulatory protein alpha and its cognate ligand CD47 as a potential signaling pathway to enhance biocompatibility. The goals of this article are to detail the known roles of CD47–signal regulatory protein alpha signal transduction pathway and to describe how immobilized CD47 can be used to mitigate the immune response to biomaterials. Current applications of CD47-modified biomaterials will also be discussed herein.
SES and Other Correlates of Health in a Youth Cohort: Implications for Social Justice

ABSTRACT This paper reports results of a study that examines the influence of socioeconomic status and other correlates on the health status of a maturing US cohort of adolescents and young adults (N = 969). Findings indicate that SES and race/ethnicity/sex remain robust predictors of physical health, while race/ethnicity/sex remains a robust predictor of mental health when controlling for hereditary, lifestyle, structural, psychological, and cumulative factors. Findings provide an empirical basis for expanding Rawls' index of social goods to include social determinants of health. They also suggest that appeals to social justice to improve physical health have more solid grounding if cast in terms of absolute gains, while such appeals to improve mental health have more solid grounding if cast in terms of relative gains based on gender. Findings also reaffirm the importance of professions like social work that stress the importance of self-determination and empowerment enabling individuals to enhance their own social functioning, and improve conditions in their communities, as well as in society at large and that incorporate social justice as an essential component of practice.
Evaluating information presentation strategies for spoken recommendations

We report the results of a Wizard-of-Oz (WoZ) study comparing two approaches to presenting information in a spoken dialogue system generating flight recommendations. We found that recommendations presented using the user-model based summarize and refine (UMSR) approach enable more efficient information retrieval than the data-driven summarize and refine (SR) approach. In addition, user ratings on four evaluation criteria showed a clear preference for recommendations based on the UMSR approach.
The Reflecting Team: Dialogues and Dialogues About the Dialogues

Operating within the reflecting team format, professionals meet clients without preexisting hypotheses. Together they engage in a conversation that becomes a search for the not-yet-seen and the not-yet-thought-of, as well as for alternative understandings of what has been defined as problematic. As clients and therapists trade places and various members of the entire group participate in conversations, the possibilities for change open wide.This book describes the evolution of this radical strategy in Tromso, Norway, and its adaptation by various family therapists in the United States. It begins in Part I with a description of the settings in which the reflecting team developed and its history and evolution. Then basic concepts, practical considerations, and guidelines for practice are detailed.Part II contains Dialogues About the Dialogues, that is, reflections on the client-therapist-consultant-team dialogues that distinguish this innovative approach to therapy. As roles shift and various participants offer definitions of the problem and possible solutions, traditional ideas about the boundaries of a "case study" are shattered. Readers will find that this fluid, encompassing perspective stimulates their own thoughts about therapy, shaking them from outgrown assumptions.Since this approach is still evolving, the final chapter is, appropriately, a reflection on the changes that have taken place since the European edition of this book was published.
The Future of Critical Management Studies: A Paleo-Marxist Critique of Labour Process Theory

For many years, the core of critical management studies was labour process theory (LPT), building on Braverman's (1976) reading of Marx. Recently, LPT has been losing momentum in favour of post-structuralist approaches. This paper takes one step back with the hope of taking critical management studies two steps forward. Whereas post-structuralists have largely discarded the Marxist foundations of LPT, this paper argues that LPT has been hobbled by its insufficiently Marxist foundations. I argue that LPT ignores the fundamental contradiction Marx saw between the progressive `socialization' of the labour process and the persistence of capitalist `valorization' constraints. Understood in Marx's terms, socialization is the movement away from local isolation towards `universal interdependence', and it is a key trend both in the objective structure of industry and in subjective self-construals. I use this framework to develop a modified conception of skill, one that reveals how capitalist development drives a process of long-term skill upgrading. On this platform, I sketch a reinterpretation of two well-known cases of work reorganization — Taylorism and lean production. In both cases, useful insight is garnered by showing how the socialization of the labour process represented by these new management principles and the associated skill upgrading was simultaneously stimulated, retarded and distorted by valorization pressures.
The Need for Reflexivity in Public Administration

In this article, the authors argue the need to go beyond the idea of reflective public administration to reflexive public administration. They explore the meaning of reflexivity, in particular self-and critical reflexivity, and suggest that reflexive practice is crucial to public administration because it can lead to more critical, responsible, and ethical actions. This can provide a basis for organizational transformation. The article concludes by offering a number of resources for teaching self-and critical reflexivity.
The association of music preferences and depressive symptoms in high school students: A community-based study from Istanbul

We investigated the association of music preferences with depressive symptoms among high school students in Istanbul; 10th-, 11th- and 12th-grade students (N = 1226) were chosen for the study. The Children’s Depression Inventory (CDI) and a detailed, semi-structured, self-report inquiry assessing music preferences and various psychosocial variables were administered to the students. Adolescents reporting heavy metal music and arabesque music in their playlists had significantly higher CDI total scores compared to adolescents who did not report these genres in their playlists. The percentage of students with problematic parent relations was highest for those with preferences for heavy metal music. Alcohol use was highest among students with preferences for dance/hip-hop music, followed by those with preferences for heavy metal. Negative thoughts and feelings when listening to music were related to higher CDI scores regardless of the favourite music genre. Future studies are needed to clarify the relationship between music preferences and specific psychopathologies in adolescents.
Artificial intelligence systems for knowledge management in e-health : the study of intelligent software agents

— In this paper, authors describe the state of art of e-health artificial intelligence systems and describe and compare the features of the multi-agent systems in e-health. The study is based on theoretical models of multi-agent systems for knowledge management in organization: information allocation, the presence of authorities, organizational norms and culture, motivating. Authors divided the e-health multi-agent systems due to the areas of supported knowledge management in e-health.
Tonotopic Organization in the Depth of Human Inferior Colliculus

Experiments in animal models indicate that inferior colliculus (IC), the primary auditory midbrain structure, represents sound frequency in a particular spatial organization, a tonotopy, that proceeds from dorsal and superficial to ventral and deeper tissue. Experiments are presented that use high-resolution, sparse-sampling functional magnetic resonance imaging (fMRI) at 3 T to determine if tonotopic gradients can be reliably measured in human IC using high-resolution fMRI. Stimuli were sequences of bandpass-filtered noise with different center frequencies, presented sequentially while fMRI data were collected. Four subjects performed an adaptive frequency-discrimination task throughout the experiment. Results show statistically significant tonotopic gradients within both ICs of all subjects. Frequency gradients as a function of depth were measured using surface-based analysis methods that make virtual penetrations into the IC tissue. This organization was evident over substantial portions of the IC, at locations that are consistent with the expected location of the central nucleus of IC. The results confirm a laminar tonotopy in the human IC at 3 T, but with a heterogeneous, patchy character. The success of these surface-based analysis methods will enable more detailed non-invasive explorations of the functional architecture of other subcortical human auditory structures that have complex, laminar organization.
Nightmares: Knowledge and attitudes in health care providers and nightmare sufferers

Chronic nightmares have a prevalence of 3 to 8% in the general population, but they seem not to play a relevant role in the health care system despite the existence of evidence-based treatments. The aim of this study was to identify nightmare-related knowledge, attitudes and coping approaches in the German mental health care system. A total of 219 health-care providers (primary care, psychiatrists, psychotherapists, in-patient versus out-patient) and another 335 nightmare sufferers were interviewed by telephone and/or filled out self-rating questionnaires. They were asked to estimate nightmare prevalence, to specify nightmare causes and how they cope with nightmares. Health care providers were asked to estimate the relevance of nightmares and the need for treatment. All groups overestimated the prevalence of nightmares. Stress, traumatic events and inner conflicts were rated the highest regarding the possible causes of nightmares, with small differences between the groups. Only a minority of nightmare sufferers tried coping strategies on their own and rated them as being moderately helpful. About one third asked health care providers for help, mainly from general practitioners and medical specialists, but rated this a little helpful. Health care providers rated the relevance of nightmares and the need for treatment as being of moderate importance. Given the high prevalence of clinically relevant nightmares and the fact that helpful and efficient treatment approaches exist, all parts of the health care system as well as the nightmare sufferers need to be better informed. That may help to decrease nightmare disorders. Key words: Nightmares, health care system, treatment, coping.
Lightning attractive radii of vertical and horizontal conductors evaluated using a self consistent leader inception and propagation model - SLIM

A self consistent lightning connecting leader inception and propagation model is utilized to study the attachment of lightning flashes to grounded structures and hence to evaluate the lightning attractive radii of vertical cylindrical structures and horizontal conductors as a function of height of the structure and peak current of the first return stroke. The attractive radius is defined as the maximum lateral distance from where the structure would be able to attract a down-coming stepped leader. Based on the results, equations that relate the attractive radius of the structure to its height and the prospective return stroke current are developed. The results to be described in the paper can be utilized to study the lightning attachment to towers or horizontal conductors of power transmission lines.
Digital Visions

This article describes some findings from recent research into young people's creative uses of new technologies in the home. The first section considers a range of theoretical perspectives on children's relationship with digital technologies. It interrogates popular and academic claims about the potential of the computer as a means for facilitating creativity. The main body of the article presents quantitative and qualitative data from the study, focusing on the ways in which children learn to use new technologies, parental regulation in the home and the role of new technologies in sustaining peer group cultures. The analysis therefore aims to situate the use of computers within wider social and cultural contexts and practices. This raises further questions about the relationship between digital technology and the formal educational system; the use of technology to define boundaries between childhood and adulthood; and assumptions about economic and vocational futures for young people in this area.
Hypermethylation of the Retinoic Acid Receptor-β2 Gene in Head and Neck Carcinogenesis

Purpose: Retinoic acid receptor-β2 (RAR-β2) expression is suppressed in oral premalignant lesions and head and neck squamous cell carcinomas (HNSCCs). This study was conducted to determine whether RAR-β2 gene expression in such lesions can be silenced by promoter methylation. Experimental Design: RAR-β2 methylation was analyzed in DNA samples from 22 pairs of primary HNSCC and adjacent normal epithelium, 124 samples of oral leukoplakia, and 18 HNSCC cell lines using methylation-specific PCR. RAR-β2 promoter was methylated in 67, 56, and 53% of HNSCC tumors, HNSCC cell lines, and microdissected oral leukoplakia specimens, respectively. RAR-β2 hypermethylation was confirmed by sodium bisulfite-PCR combined with restriction enzyme digestion analysis and by random cloning and sequencing of bisulfite-treated DNA isolates. Results: Significantly higher RAR-β2 hypermethylation levels were found in tumor tissue compared with adjacent normal tissue (P = 0.002). RAR-β2 methylation in the cell lines was correlated with loss of RAR-β2 expression (P = 0.013) and inversely related to the presence of mutated p53 (P = 0.025). The demethylating agent 5-aza-2′-deoxycytidine (5-aza-CdR) restored RAR-β2 inducibility by all-trans-retinoic acid (ATRA) in some of the cell lines, which posses a methylated RAR-β2 promoter. In some cell lines, this effect was associated with increased growth inhibition after combined treatment with 5-aza-CdR and ATRA. Conclusions: RAR-β2 silencing by methylation is an early event in head and neck carcinogenesis; 5-Aza-CdR can restore RAR-β2 inducibility by ATRA in most cell lines, and the combination of 5-aza-CdR and ATRA is more effective in growth inhibition than single agents.
Simulation of AC-DC step up and step down converter

Various applications in the modern world require DC supply. Some applications needs low DC voltage and some require considerably high DC voltage. We get AC supply and that needs to be converted to DC for these applications. In this paper AC - DC step up and step down converters without the use of bridge rectification is dealt. In step up converter, low AC voltage micro generators are used and the DC output voltage is boosted. The step up converter consists of a combination of boost converter in parallel with a buck-boost converter, which are operated in the positive half cycle and negative half cycle respectively. In step down converter, single phase AC voltage is converted into low DC output voltage. The step down converter consists of a combination of buck converter in parallel with a buck-boost converter, which are operated in the positive half cycle and negative half cycle respectively.
