    2012-06-01

    Dajana currently has 21 peer-reviewed articles published or accepted for publication in top analytical chemistry journals including Analytical Chemistry and Angewandte Chemie International Edition. She has co-authored eight book chapters, and made 22 presentations at international conferences such as Pittcon and ASMS conferences. Dajana's commitment to excellence is also illustrated by the awards she has won to date, including a Postdoctoral Fellow Award offered by the Natural Science and Engineering Research Council of Canada (2010-2012) and the Douglas E Ryan Analytical Chemistry Student Award of the Canadian Society for Chemistry (2010). During her PhD in my group, Dajana excelled in very diverse areas of interest including the development of targeted LC-MS assays for drugs and metabolites, application of in vivo solid-phase microextraction (SPME) in mice and LC-MS metabolomics for the first time, and evaluation of a high-throughput 96-well plate automated SPME system. Since her graduation from my group she has further extended her bioanalytical expertise to proteomics. I think Dajana's excellent research productivity, accomplishments to date, willingness to address complex bioanalytical challenges and extensive expertise in both small molecule and protein bioanalysis make her an excellent candidate for the Bioanalysis Young Investigator Award.

    It is with great pleasure that I am writing to recommend Sathyadevi Venkataramani who works as a Scientist in Integrated BioTherapeutics (IBT). Sathya did her graduate research work at the University of Zurich (Switzerland) where she focused on using various bioanalytical tools to characterize the stability of repeat proteins that are emerging as excellent alternatives to antibody therapy. She successfully published her research findings in journals including Protein Science, Biochemistry and Current Microbiology. As a postdoctoral associate at Stanford University (CA, USA) and as a Scientist in Solus Biosystems (CA, USA), she thoroughly investigated the applications of spectroscopy and chromatography for characterizing the stability of monoclonal antibodies and other therapeutic proteins. Being the first author in all her publications and corresponding author of her last few highlights her highly competent skills (both writing and oral), enthusiasm, research motivation, hard work, scientific capabilities, innovative thinking and the terrific passion in implementing those. I am very impressed that she is serving as an ad-hoc peer reviewer for journals such as Molecular Biology Reports, American Association of Pharmaceutical Scientists PharmSciTech, Research and Reports in Biochemistry and as a Faculty of Biochemistry for Webmed Central. Currently she is leading the protein chemistry group in Integrated BioTherapeutics, Inc. (IBT) and is already in possession of a couple of manuscripts and patents from IBT. Her expertise and unquenchable enthusiasm in the bioanalysis field have tremendously helped to improve the quality and quantity of proteins in IBT. It is a very commendable idea of Bioanalysis to appreciate and recognize the young rising stars of the scientific world and I am very excited and honored to recommend Sathya among those for the year 2012.

  7. Understanding the CCA Standard Through Decaf

    Energy Technology Data Exchange (ETDEWEB)

    Kumfert, G

    2003-04-17

    This document is a tutorial on the CCA Standard as realized through the Decaf implementation. Decaf does not equal the CCA standard much in the same way that Microsoft Visual C++ is not ANSI/ISO C++. This document was created because the CCA standard is evolving and still too fluid to nail down in a tutorial document. Because of its fluidity, and that it represents a hotbed of research and development, beginners can only start learning CCA by choosing one of the frameworks (warts and all). Decaf has just enough functionality to be a useful tool for beginners in the CCA to get started on. Though it lacks many features of the bigger CCA frameworks (CCAFE [3], XCAT [10], and SciRUN [8]) where the heavy-duty research is still going on, it is the first CCA framework that is underpinned by Babel, which provides its language interoperability features. This document can also serve the dual-purpose of providing a reasonable-sized example of building an application using Babel. The entire source for Decaf is included in the examples/subdirectory of the Babel code distribution. This manual assumes the reader is a programmer who has a conceptual understanding of the Babel Language Interoperability Tool. They should be proficient in two or more of the following languages: Fortran77, C, C++, Java, or Python. Furthermore, this manual assumes the reader is familiar with the SPMD{sup 2} programming model that pervades the scientific computing community. Knowledge of and experience with MPI programming is helpful, but not strictly required.

Yes the answer is face recognition. In this study we explore and compare the performance of three algorithms namely LDA, CCA, AAM. LDA (an evolution of PCA is a dimensionality reduction technique where it solves the problem of illumination to some extent, maximizing the inter class separation and minimizing the intra class variations. CCA, a measure of linear relationship between two multidimensional variables where it takes the advantage of PCA and LDA for maximizing the correlation and better performance. AAM is a model based approach where it just picks the landmarks of the images for recognition therefore reducing the error rate and producing good performance rate.

  12. Evaluation of urine CCA assays for detection of Schistosoma mansoni infection in Western Kenya.

    Hillary L Shane

    Full Text Available Although accurate assessment of the prevalence of Schistosoma mansoni is important for the design and evaluation of control programs, the most widely used tools for diagnosis are limited by suboptimal sensitivity, slow turn-around-time, or inability to distinguish current from former infections. Recently, two tests that detect circulating cathodic antigen (CCA in urine of patients with schistosomiasis became commercially available. As part of a larger study on schistosomiasis prevalence in young children, we evaluated the performance and diagnostic accuracy of these tests--the carbon test strip designed for use in the laboratory and the cassette format test intended for field use. In comparison to 6 Kato-Katz exams, the carbon and cassette CCA tests had sensitivities of 88.4% and 94.2% and specificities of 70.9% and 59.4%, respectively. However, because of the known limitations of the Kato-Katz assay, we also utilized latent class analysis (LCA incorporating the CCA, Kato-Katz, and schistosome-specific antibody results to determine their sensitivities and specificities. The laboratory-based CCA test had a sensitivity of 91.7% and a specificity of 89.4% by LCA while the cassette test had a sensitivity of 96.3% and a specificity of 74.7%. The intensity of the reaction in both urine CCA tests reflected stool egg burden and their performance was not affected by the presence of soil transmitted helminth infections. Our results suggest that urine-based assays for CCA may be valuable in screening for S. mansoni infections.

    Lowe, C S; Radius, S M

    1987-01-01

    This study investigated young adults' contraceptive behaviors and attitudes through application of a comprehensive, theoretical framework. Specifically, a social-psychological approach to understanding preventive behaviors (e.g., contraceptive practices), was developed, incorporating the Health Belief Model and other factors, which offered a means for evaluating the extent to which contraceptive behaviors were influenced by individual and group characteristics. The study group consisted of 283 unmarried students at several schools who were, on average, 19 years of age. Results suggested that effective contraceptive behavior associated most strongly with respondents' perceiving relatively few barriers to their use of contraception, their maintenance of extensive interpersonal skills, and their regarding peer norms as consistent with effective contraceptive behavior. Findings also underlined a need for continuing education about sexuality and contraception. Dangerous misinformation prevailed regarding respondents' knowledge of areas that include anatomy, physiology, and appropriate use of effective contraceptive methods. Finally, results implied a need to consider broad behavioral, social, and interpersonal issues as they relate to young adults' effective contraceptive behavior. Future studies of contraceptive risk taking are encouraged to examine both individual and social factors affecting sexual and contraceptive practices if unplanned pregnancy is to be minimized, if not eliminated.

  19. Isolation and characterization of human brain genes with (CCA){sub n} trinucleotide repeats

    Longshore, J.W.; Finley, W.H.; Descartes, M. [Univ. of Alabama, Birmingham, AL (United States)] [and others

    1994-09-01

    Expansion of trinucleotide repeats has been described as a new form of mutation. To date, only the expansion of (CGG){sub n} and (CAG){sub n} repeats have been associated with disease. Expansion of (CAG){sub n} repeats has been found to cause Huntington`s disease, Kennedy`s disease, myotonic dystrophy, spinocerebellar ataxia type 1, and dentatorubral pallidoluysian atrophy. (CGG){sub n} repeat expansion has been implicated in the fragile X syndrome and FRAXE mental retardation. In an effort to identify other potential repeats as candidates for expansion, a DNA linguistics approach was used to study 10 Mb of human DNA sequences in GenBank. Our study found the (CCA){sub n} repeat and the disease-associated (CGG){sub n} and (CAG){sub n} repeats to be over-represented in the human genome. The (CCA){sub n} repeat also shares other characteristics with (CGG){sub n} and (CAG){sub n}, making it a good candidate for expansion. Trinucleotide repeat numbers in disease-associated genes are normally polymorphic in a population. Therefore, by studying genes for polymorphisms, candidate genes may be identified. Twelve sequences previously deposited in GenBank with at least five tandem copies of (CCA) were studied and no polymorphisms were found. To identify other candidate genes, a human hippocampus cDNA library was screened with a (CCA){sub 8} probe. This approach identified 19 novel expressed sequences having long tandem (CCA){sub n} repeats which are currently under investigation for polymorphisms. Genes with polymorphic repeats may serve as markers for linkage studies or as candidate genes for genetic diseases showing anticipation.

The results showed that arsenic may be the easiest removable of the copper, chromium and arsenic investigated here. This is very encouraging since arsenic is the CCA components of most environmental concern....

  1. An investigation of young girls' responses to sexualized images.

    Jongenelis, Michelle I; Pettigrew, Simone; Byrne, Susan M; Biagioni, Nicole

    2016-12-01

    Evidence suggests that the sexualization of girls has increased and become more explicit in recent years. However, most of the research conducted to date has focused on sexualization in adults. To address this research gap, this study explored how young Australian girls respond to and describe sexualized and non-sexualized depictions of their peers. Results from 42 girls aged 6-11 years revealed that sexualization was a perceptually salient attribute, with participants readily classifying sexualized girls as a subgroup. Participants also made distinct trait attributions based on the differences between sexualized and non-sexualized girls. The results suggest that young girls respond differently to sexualized and non-sexualized depictions of their peers and are beginning to develop stereotypes based on these depictions. As such, the implementation of media literacy programs in adolescence may be too late and efforts may be required to address this issue among younger children.

    This study reports a survey of occupational exposure to copper chrome arsenic (CCA) based wood preservatives during vacuum pressure timber impregnation. The survey involved biological monitoring based on analysis of chromium and arsenic in urine samples collected from UK workers. The aim of the study was to determine the extent of occupational exposure to arsenic and chromium in the UK timber treatment industry. The objectives were to collect and analyse urine samples from as many workers as possible, where CCA wood preservatives might be used, at 6 monthly intervals for 2 years. In addition, to investigate day-to-day variations in urinary excretion of chrome and arsenic by collecting and analysing three samples a week for 3 weeks in subsets of workers and controls (people not occupationally exposed). All urine samples were analysed for chromium and inorganic arsenic. To investigate any residual interference every sample was accompanied by a short questionnaire about recent consumption of seafood and smoking. The analytical methods for arsenic used a hydride generation technique to reduce interference from dietary sources of arsenic and also a technique that would measure total arsenic concentration in urine. The main findings show that workers exposed to CCA wood preservatives have concentrations of inorganic arsenic and chromium in urine that are significantly higher than those from non-occupationally exposed people but below biological monitoring guidance values that would indicate inhalation exposure at UK occupational exposure limits for chromium and arsenic. The effects of consumption of seafood on urinary arsenic were not significant using the hydride generation method for inorganic arsenic but were significant if 'total' arsenic was measured. The 'total' arsenic method could not distinguish CCA workers from controls and is clearly unsuitable for assessment of occupational exposure to arsenic. There was a significant increase in the urinary concentration of

    A double-negative feedback loop formed by the morning genes CIRCADIAN CLOCK ASSOCIATED1 (CCA1)/LATE ELONGATED HYPOCOTYL (LHY) and the evening gene TIMING OF CAB EXPRESSION1 (TOC1) contributes to regulation of the circadian clock in Arabidopsis. A 24-h circadian cycle starts with the peak expression of CCA1 at dawn. Although CCA1 is targeted by multiple transcriptional repressors, including PSEUDO-RESPONSE REGULATOR9 (PRR9), PRR7, PRR5 and CCA1 HIKING EXPEDITION (CHE), activators of CCA1 remain elusive. Here we use mathematical modelling to infer a co-activator role for LIGHT-REGULATED WD1 (LWD1) in CCA1 expression. We show that the TEOSINTE BRANCHED 1-CYCLOIDEA-PCF20 (TCP20) and TCP22 proteins act as LWD-interacting transcriptional activators. The concomitant binding of LWD1 and TCP20/TCP22 to the TCP-binding site in the CCA1 promoter activates CCA1. Our study reveals activators of the morning gene CCA1 and provides an action mechanism that ensures elevated expression of CCA1 at dawn to sustain a robust clock. PMID:27734958

    2006-08-15

    Arsenic from chromated copper arsenate (CCA)-treated wood, widely used in playgrounds and other outdoor equipment, can persist as surface residues on wood. This raises concerns about possible health risks associated with children playing on CCA-treated playgrounds. In a Pilot Study, 11 children (13-71 months) in homes with and without CCA-treated playgrounds were evaluated with post-exposure hand rinses and urine for total arsenic. Samples of wood, soil, and mulch, as well as synthetic wipes, were sampled for total arsenic. In non-CCA-treated playgrounds vs. CCA-treated playgrounds, respectively, wood arsenic was soil arsenic was playground was 0.4 mg/kg vs. two CCA-treated playgrounds of 0.6 and 69 mg/kg. The arsenic removed using a synthetic wipe at non-CCA-treated playgrounds was playgrounds was playgrounds. Mean urinary total arsenic levels were 13.6 pg/ml (range 7.2-23.1 pg/ml) for all children evaluated, but there was no association between access to CCA-playgrounds and urinary arsenic levels. Arsenic speciation was not performed. This preliminary Pilot Study of CCA-treated wood playgrounds observed dislodgeable arsenic on 11 children's hands after brief periods of play exposure. Future efforts should increase the number of children and the play exposure periods, and incorporate speciation in order to discriminate between various sources of arsenic.

    2017-02-22

    Landing a job as an assistant professor or independent investigator in neuroscience in an academic institution or research institute depends on the accomplishments young scientists make during years of training as graduate students and postdoctoral fellows. This training prepares scientists for an array of exciting job opportunities, one of which is as a faculty member or independent investigator. My goal in this NeuroView is to provide tips about the job search for young scientists who have decided to enter the junior faculty/independent investigator job market. Rather than serving as a "protocol for getting a job," these tips are aimed at providing information that will make each candidate better prepared for her or his job search.

  16. What's it all about? Investigating reading comprehension strategies in young adults with down syndrome.

    Science.gov (United States)

    Morgan, Michelle; Moni, Karen B; Jobling, Anne

    2004-07-01

    The purpose of reading is for the reader to construct meaning from the text. For many young adults with Down syndrome, knowing what the text is all about is difficult, and so for them the activity of reading becomes simply the practice of word calling. It is suggested in the literature that for those individuals with Down syndrome, learning can continue into adolescence and that this may be the optimal time for learning to occur. However, a review of the literature revealed limited empirical research specifically relating to the reading comprehension of young adults with Down syndrome. Recent findings from Latch-On (Literacy And Technology Hands On), a research-based literacy and technology program for young adults with Down syndrome at the University of Queensland, revealed that comprehension remained the significant area of difficulty and showed least improvement (Moni & Jobling, 2001). It was suggested by Moni and Jobling (2001) that explicit instruction in comprehension using a variety of strategies and meaningful, relevant texts was required to improve the ability of young adults with Down syndrome to construct meaning from written texts. This paper is based on an action research project that was developed within the Latch-On program. The project utilised a modification of Elliot's (1991) action research model and was conducted to investigate specific teaching and learning strategies that would enhance the reading comprehension of young adults with Down syndrome. The participants were 6 young adults with Down syndrome ranging in age from 18 to 25 years. As the data from this project are still being analysed, preliminary findings of one participant are presented as a case study. The preliminary findings appear to indicate that the program of specific teaching and learning reading comprehension strategies used in this project was beneficial in the participant's reading comprehension.

    The rapid pace of motorisation in China has been well documented, as has the large road trauma burden the Chinese citizens are facing as a result. China's unique political system represents an important consideration in helping reduce road trauma, yet political factors have not been previously investigated in this context. Recently, emerging issues on the road involving the adult children of politically powerful families have become a serious social problem in China, and have drawn widespread media and public attention. This study took a novel approach to examining factors associated with risky attitudes and risky road use in China by investigating the economic and political background status of a sample of young Chinese drivers. An online survey was conducted in May 2015 with a sample size of 476 Chinese young drivers from across the country, aged between 18 and 28, including 305 males and 171 females. The results suggest that for participants who reported having a familial political background, more risky driving behaviours were reported among those participants who reported more impact on their life from that political background; while for participants without political background, higher personal income was associated with more risky driving behaviours. The findings are discussed in light of China's political management system and potential education opportunities for young drivers.

    Objective. Recently developed effective methods for detection commands of steady-state visual evoked potential (SSVEP)-based brain–computer interface (BCI) that need calibration for visual stimuli, which cause more time and fatigue prior to the use, as the number of commands increases. This paper develops a novel unsupervised method based on canonical correlation analysis (CCA) for accurate detection of stimulus frequency. Approach. A novel unsupervised technique termed as binary subband CCA (BsCCA) is implemented in a multiband approach to enhance the frequency recognition performance of SSVEP. In BsCCA, two subbands are used and a CCA-based correlation coefficient is computed for the individual subbands. In addition, a reduced set of artificial reference signals is used to calculate CCA for the second subband. The analyzing SSVEP is decomposed into multiple subband and the BsCCA is implemented for each one. Then, the overall recognition score is determined by a weighted sum of the canonical correlation coefficients obtained from each band. Main results. A 12-class SSVEP dataset (frequency range: 9.25–14.75 Hz with an interval of 0.5 Hz) for ten healthy subjects are used to evaluate the performance of the proposed method. The results suggest that BsCCA significantly improves the performance of SSVEP-based BCI compared to the state-of-the-art methods. The proposed method is an unsupervised approach with averaged information transfer rate (ITR) of 77.04 bits min‑1 across 10 subjects. The maximum individual ITR is 107.55 bits min‑1 for 12-class SSVEP dataset, whereas, the ITR of 69.29 and 69.44 bits min‑1 are achieved with CCA and NCCA respectively. Significance. The statistical test shows that the proposed unsupervised method significantly improves the performance of the SSVEP-based BCI. It can be usable in real world applications.

    Widespread use of chromated copper arsenate (CCA) as a wood preservative has led to increasing public concern regarding possible toxic contamination of areas surrounding CCA-treated structures, e.g., decks, playground equipment, etc. Appreciable leaching of arsenic, chromium, and copper into soils adjacent to such structures has been demonstrated via standard techniques of analytical chemistry. The advantages of PIXE [rapid analysis, quick sample turnover, possible lower cost] suggest its application to this area of interest. PIXE studies in our laboratory of CCA-contaminated soil samples show good agreement with previous analyses of As, Cu, Cr, and other heavy-elemental content, with some variability in diffusion rates.

    The putative regulatory CcaR protein, which is encoded in the beta-lactam supercluster of Streptomyces clavuligerus, has been partially purified by ammonium sulfate precipitation and heparin affinity chromatography. In addition, it was expressed in Escherichia coli, purified as a His-tagged recombinant protein (rCcaR), and used to raise anti-rCcaR antibodies. The partially purified CcaR protein from S. clavuligerus was able to bind DNA fragments containing the promoter regions of the ccaR gene itself and the bidirectional cefD-cmcI promoter region. In contrast, CcaR did not bind to DNA fragments with the promoter regions of other genes of the cephamycin-clavulanic acid supercluster including lat, blp, claR, car-cyp, and the unlinked argR gene. The DNA shifts obtained with CcaR were prevented by anti-rCcaR immunoglobulin G (IgG) antibodies but not by anti-rabbit IgG antibodies. ccaR and the bidirectional cefD-cmcI promoter region were fused to the xylE reporter gene and expressed in Streptomyces lividans and S. clavuligerus. These constructs produced low catechol dioxygenase activity in the absence of CcaR; activity was increased 1.7- to 4.6-fold in cultures expressing CcaR. Amplification of the ccaR promoter region lacking its coding sequence in a high-copy-number plasmid in S. clavuligerus ATCC 27064 resulted in a reduced production of cephamycin C and clavulanic acid, by 12 to 20% and 40 to 60%, respectively, due to titration of the CcaR regulator. These findings confirm that CcaR is a positively acting autoregulatory protein able to bind to its own promoter as well as to the cefD-cmcI bidirectional promoter region.

  1. Children's exposure to arsenic from CCA-treated wooden decks and playground structures.

    CCA-treated wood is widely used in the fabrication of outdoor decks and playground equipment. Because arsenic can be removed from the surface of CCA-treated wood both by physical contact and by leaching, it is important to determine whether children who play on such structures may ingest arsenic in quantities sufficient to be of public health concern. Based on a review of existing studies, it is estimated that arsenic doses in amounts of tens of micrograms per day may be incurred by children having realistic levels of exposure to CCA-treated decks and playground structures. The most important exposure pathway appears to be oral ingestion of arsenic that is first dislodged from the wood by direct hand contact, then transferred to the mouth by children's hand-to-mouth activity. The next most important pathway appears to be dermal absorption of arsenic, while ingestion of soil that has become contaminated by leaching from CCA-treated structures appears to be of lesser importance, except possibly in the case of children with pica. Considerable uncertainty, however, is associated with quantitative estimates of children's arsenic exposure from CCA-treated wood. Priorities for refining estimates of arsenic dose include detailed studies of the hand-to-mouth transfer of arsenic, studies of the dermal and gastrointestinal absorption of dislodgeable arsenic, and studies in which doses of arsenic to children playing in contact with CCA-treated wood are directly determined by measurement of arsenic in their urine, hair, and nails.

    We present a multiwavelength investigation of the young stellar population and star formation activities around the \\hii region Sharpless 311. Using our deep near-infrared observations and archival {\\it Spitzer}-IRAC observations, we have detected a total of 125 young stellar objects (YSOs) in an area of $\\sim$86 arcmin$^2$. The YSOs sample include 8 Class I and 117 Class II candidate YSOs. The mass completeness of the identified YSOs sample is estimated to be 1.0 \\msun. The ages and masses of the majority of the candidate YSOs are estimated to be in the range of $\\sim$0.1$-$5 Myr and $\\sim$0.3$-$6 \\msun, respectively. The 8 \\mum image of S311 displays an approximately spherical cavity around the ionizing source which is possibly created due to the expansion of the \\hii region. The spatial distribution of the candidate YSOs reveals that a significant number of them are distributed systematically along the 8 $\\mu$m emission with a majority clustered around the eastern border of the \\hii region.

    The remediation of chromated copper arsenate or CCA-treated wood is a challenging problem in many countries. In a wet remediation, the recycling of the washing solutions is the key step for a successful process. Within this goal, owing to its solubility and its toxicity, the removal of arsenic from washing solution is the most difficult process. The efficiency of arsenic removal from As(III) solutions by electrolysis was investigated in view of the recycling of acidic washing solutions usable in the remediation of CCA-treated wood. Electrochemical reduction of As(III) is irreversible and thus difficult to perform at carbon electrodes. However the electrolytic extraction of arsenic can be performed by the concomitant reduction of the cupric cation and arsenite anion. The cathodic deposits obtained by controlled potential electrolysis were analyzed by X-ray diffraction (XRD) and energy dispersive X-ray microanalysis. XRD diffraction data indicated that these deposits were mixtures of copper and copper arsenides Cu(3)As and Cu(5)As(2). Electrolysis was carried out in an undivided cell with graphite cathode and copper anode, under a controlled nitrogen atmosphere. The evolution of arsine gas AsH(3) was not observed under these conditions.

  5. Role of the CCA bulge of prohead RNA of bacteriophage ø29 in DNA packaging.

    The oligomeric ring of prohead RNA (pRNA) is an essential component of the ATP-driven DNA packaging motor of bacteriophage ø29. The A-helix of pRNA binds the DNA translocating ATPase gp16 (gene product 16) and the CCA bulge in this helix is essential for DNA packaging in vitro. Mutation of the bulge by base substitution or deletion showed that the size of the bulge, rather than its sequence, is primary in DNA packaging activity. Proheads reconstituted with CCA bulge mutant pRNAs bound the packaging ATPase gp16 and the packaging substrate DNA-gp3, although DNA translocation was not detected with several mutants. Prohead/bulge-mutant pRNA complexes with low packaging activity had a higher rate of ATP hydrolysis per base pair of DNA packaged than proheads with wild-type pRNA. Cryoelectron microscopy three-dimensional reconstruction of proheads reconstituted with a CCA deletion pRNA showed that the protruding pRNA spokes of the motor occupy a different position relative to the head when compared to particles with wild-type pRNA. Therefore, the CCA bulge seems to dictate the orientation of the pRNA spokes. The conformational changes observed for this mutant pRNA may affect gp16 conformation and/or subsequent ATPase-DNA interaction and, consequently, explain the decreased packaging activity observed for CCA mutants.

  6. CCA performance of a new source list/EZW hybrid compression algorithm

    A new data compression algorithm for encoding astronomical source lists is presented. Two experiments in combined compression and analysis (CCA) are described, the first using simulated imagery based upon a tractable source list model, and the second using images from SPIRIT III, a spaceborne infrared sensor. A CCA system consisting of the source list compressor followed by a zerotree-wavelet residual encoder is compared to alternatives based on three other astronomical image compression algorithms. CCA performance is expressed in terms of image distortion along with relevant measures of point source detection and estimation quality. Some variations of performance with compression bit rate and point source flux are characterized. While most of the compression algorithms reduce high-frequency quantum noise at certain bit rates, conclusive evidence is not found that such denoising brings an improvement in point source detection or estimation performance of the CCA systems. The proposed algorithm is a top performer in every measure of CCA performance; the computational complexity is relatively high, however.

  7. 2D-3D Face Recognition Method Based on a Modified CCA-PCA Algorithm

    2014-03-01

    Full Text Available This paper presents a proposed methodology for face recognition based on an information theory approach to coding and decoding face images. In this paper, we propose a 2D-3D face-matching method based on a principal component analysis (PCA algorithm using canonical correlation analysis (CCA to learn the mapping between a 2D face image and 3D face data. This method makes it possible to match a 2D face image with enrolled 3D face data. Our proposed fusion algorithm is based on the PCA method, which is applied to extract base features. PCA feature-level fusion requires the extraction of different features from the source data before features are merged together. Experimental results on the TEXAS face image database have shown that the classification and recognition results based on the modified CCA-PCA method are superior to those based on the CCA method. Testing the 2D-3D face match results gave a recognition rate for the CCA method of a quite poor 55% while the modified CCA method based on PCA-level fusion achieved a very good recognition score of 85%.

    Animal enclosures are often constructed from wood treated with the pesticide chromated copper arsenate (CCA), which leaches arsenic (As) into adjacent soil during normal weathering. This study evaluated potential pathways of As exposure in 25 species of zoo animals living in CCA-wood enclosures. We analyzed As speciation in complete animal foods, dislodgeable As from CCA-wood, and As levels in enclosure soils, as well as As levels in biomarkers of 9 species of crocodilians (eggs), 4 species of birds (feathers), 1 primate species (hair), and 1 porcupine species (quills). Elevated soil As in samples from 17 enclosures was observed at 1.0-110mg/kg, and enclosures housing threatened and endangered species had As levels higher than USEPA's risk-based Eco-SSL for birds and mammals of 43 and 46mg/kg. Wipe samples of CCA-wood on which primates sit had dislodgeable As residues of 4.6-111μg/100cm(2), typical of unsealed CCA-wood. Inorganic As doses from animal foods were estimated at 0.22-7.8μg/kg bw/d. Some As levels in bird feathers and crocodilian eggs were higher than prior studies on wild species. However, hair from marmosets had 6.37mg/kg As, 30-fold greater than the reference value, possibly due to their inability to methylate inorganic As. Our data suggested that elevated As in soils and dislodgeable As from CCA-wood could be important sources of As exposure for zoo animals.

    AIM: To study the role of focal adhesion kinase (FAK) and its association with Src in hepatocyte growth factor (HGF)-induced cell signaling in cholangiocarcinoma progression.METHODS: Previously isolated HuCCA-1 cells were re-characterized by immunofluorescent staining and reverse transcriptase-polymerase chain reaction assay for the expression of cytokeratin 19, HGF and c-Met mRNA. Cultured HuCCA-1 cells were treated with HGF and determined for cell proliferation and invasion effects by MTT and invasion assays. Western blotting, immunoprecipitation, and co-immunoprecipitation were also performed to study the phosphorylation and interaction of FAK and Src. A novel Src inhibitor (AZM555130) was applied in cultures to investigate the effects on FAK phosphorylation inhibition and on cell proliferation and invasion.RESULTS: HGF enhanced HuCCA-1 cell proliferation and invasion by mediating FAK and Src phosphorylations.FAK-Src interaction occurred in a time-dependent manner that Src was proved to be an upstream signaling molecule to FAK. The inhibitor to Src decreased FAK phosphorylation level in correlation with the reduction of cell proliferation and invasion.CONCLUSION: FAK plays a significant role in signaling pathway of HGF-responsive cell line derived from cholangiocarcinoma. Autophosphorylated Src, induced by HGF, mediates Src kinase activation, which subsequently phosphorylates its substrate, FAK, and signals to cell proliferation and invasion.

    The present study investigated second-graders' self-regulative behav ior during task engagement and its relations to performance and to students' on-line metacognitive experiences. Participants were 25 individually examined Greek second graders (13 boys and 12 girls; M age: 7.6 yr., SD = 0.2). Students' use of cognitive, metacognitive, and motivational regulatory strategies while performing a cognitive task were directly observed and recorded by two independent observers. Students' task-specific performance was also evaluated. Finally, students' feeling of satisfaction with the solution produced, their estimate of effort expenditure, and estimate of the solution's correctness were assessed. Analysis showed these second grade students' use of self-regulatory strategies and feeling of satisfaction were significantly associated with their performance. However, metacognitive experiences reported after the solution were only slightly related to the students' actual self-regulative behavior during the task, implying that the relations of students' regulatory efforts with their metacognitive processes are still developing at such a young age.

    It has been suggested that the memory enhancing effect of glucose follows an inverted U-shaped curve, with 25 g resulting in optimal facilitation in healthy young adults. The aim of this study was to further investigate the dose dependency of the glucose facilitation effect in this population across different memory domains and to assess moderation by interindividual differences in glucose regulation and weight. Following a double-blind, repeated measures design, 30 participants were administered drinks containing five different doses of glucose (0 g, 15 g, 25 g, 50 g, and 60 g) and were tested across a range of memory tasks. Glycaemic response and changes in mood state were assessed following drink administration. Analysis of the data showed that glucose administration did not affect mood, but significant glucose facilitation of several memory tasks was observed. However, dose-response curves differed depending on the memory task with only performance on the long-term memory tasks adhering largely to the previously observed inverted U-shaped dose-response curve. Moderation of the response profiles by interindividual differences in glucose regulation and weight was observed. The current data suggest that dose-response function and optimal dose might depend on cognitive domain and are moderated by interindividual differences in glucose regulation and weight.

  19. A preliminary investigation of materialism and impulsiveness as predictors of technological addictions among young adults.

    2013-03-01

    Background and aims The primary objective of the present research is to investigate the drivers of technological addiction in college students - heavy users of Information and Communication Technology (ICT). The study places cell phone and instant messaging addiction in the broader context of consumption pathologies, investigating the influence of materialism and impulsiveness on these two technologies. Clearly, cell phones serve more than just a utilitarian purpose. Cell phones are used in public and play a vital role in the lives of young adults. The accessibility of new technologies, like cell phones, which have the advantages of portability and an ever increasing array of functions, makes their over-use increasingly likely. Methods College undergraduates (N = 191) from two U.S. universities completed a paper and pencil survey instrument during class. The questionnaire took approximately 15-20 minutes to complete and contained scales that measured materialism, impulsiveness, and mobile phone and instant messaging addiction. Results Factor analysis supported the discriminant validity of Ehrenberg, Juckes, White and Walsh's (2008) Mobile Phone and Instant Messaging Addictive Tendencies Scale. The path model indicates that both materialism and impulsiveness impact the two addictive tendencies, and that materialism's direct impact on these addictions has a noticeably larger effect on cell phone use than instant messaging. Conclusions The present study finds that materialism and impulsiveness drive both a dependence on cell phones and instant messaging. As Griffiths (2012) rightly warns, however, researchers must be aware that one's addiction may not simply be to the cell phone, but to a particular activity or function of the cell phone. The emergence of multi-function smart phones requires that research must dig beneath the technology being used to the activities that draw the user to the particular technology.

    Full Text Available BACKGROUND: Promising results have been reported for a urine circulating cathodic antigen (CCA test for the diagnosis of Schistosoma mansoni. We assessed the accuracy of a commercially available CCA cassette test (designated CCA-A and an experimental formulation (CCA-B for S. mansoni diagnosis. METHODOLOGY: We conducted a cross-sectional survey in three settings of Côte d'Ivoire: settings A and B are endemic for S. mansoni, whereas S. haematobium co-exists in setting C. Overall, 446 children, aged 8-12 years, submitted multiple stool and urine samples. For S. mansoni diagnosis, stool samples were examined with triplicate Kato-Katz, whereas urine samples were tested with CCA-A. The first stool and urine samples were additionally subjected to an ether-concentration technique and CCA-B, respectively. Urine samples were examined for S. haematobium using a filtration method, and for microhematuria using Hemastix dipsticks. PRINCIPAL FINDINGS: Considering nine Kato-Katz as diagnostic 'gold' standard, the prevalence of S. mansoni in setting A, B and C was 32.9%, 53.1% and 91.8%, respectively. The sensitivity of triplicate Kato-Katz from the first stool and a single CCA-A test was 47.9% and 56.3% (setting A, 73.9% and 69.6% (setting B, and 94.2% and 89.6% (setting C. The respective sensitivity of a single CCA-B was 10.4%, 29.9% and 75.0%. The ether-concentration technique showed a low sensitivity for S. mansoni diagnosis (8.3-41.0%. The specificity of CCA-A was moderate (76.9-84.2%; CCA-B was high (96.7-100%. The likelihood of a CCA-A color reaction increased with higher S. mansoni fecal egg counts (odds ratio: 1.07, p<0.001. A concurrent S. haematobium infection or the presence of microhematuria did not influence the CCA-A test results for S. mansoni diagnosis. CONCLUSION/SIGNIFICANCE: CCA-A showed similar sensitivity than triplicate Kato-Katz for S. mansoni diagnosis with no cross-reactivity to S. haematobium and microhematuria. The low sensitivity

    The common carotid artery (CCA) is a source of important information that doctors can use to evaluate the patients' health. The most often measured parameters are arterial stiffness, lumen diameter, wall thickness, and other parameters where variation with time is usually measured. Unfortunately, the manual measurement of dynamic parameters of the CCA is time consuming, and therefore, for practical reasons, the only alternative is automatic approach. The initial localization of artery is important and must precede the main measurement. This article describes a novel method for the localization of CCA in the transverse section of a B-mode ultrasound image. The novel method was designed automatically by using the grammar-guided genetic programming (GGGP). The GGGP searches for the best possible combination of simple image processing tasks (independent building blocks). The best possible solution is represented with the highest detection precision. The method is tested on a validation database of CCA images that was specially created for this purpose and released for use by other scientists. The resulting success of the proposed solution was 82.7%, which exceeded the current state of the art by 4% while the computation time requirements were acceptable. The paper also describes an automatic method that was used in designing the proposed solution. This automatic method provides a universal approach to designing complex solutions with the support of evolutionary algorithms.

    Animal enclosures are often constructed from wood treated with the pesticide chromated copper arsenate (CCA), which leaches arsenic (As) into adjacent soil during normal weathering. This study evaluated potential pathways of As exposure in 25 species of zoo animals living in CCA-wood enclosures. We analyzed As speciation in complete animal foods, dislodgeable As from CCA-wood, and As levels in enclosure soils, as well as As levels in biomarkers of 9 species of crocodilians (eggs), 4 species of birds (feathers), 1 primate species (hair), and 1 porcupine species (quills). Elevated soil As in samples from 17 enclosures was observed at 1.0–110 mg/kg, and enclosures housing threatened and endangered species had As levels higher than USEPA's risk-based Eco-SSL for birds and mammals of 43 and 46 mg/kg. Wipe samples of CCA-wood on which primates sit had dislodgeable As residues of 4.6–111 μg/100 cm{sup 2}, typical of unsealed CCA-wood. Inorganic As doses from animal foods were estimated at 0.22–7.8 μg/kg bw/d. Some As levels in bird feathers and crocodilian eggs were higher than prior studies on wild species. However, hair from marmosets had 6.37 mg/kg As, 30-fold greater than the reference value, possibly due to their inability to methylate inorganic As. Our data suggested that elevated As in soils and dislodgeable As from CCA-wood could be important sources of As exposure for zoo animals. - Highlights: • Daily inorganic As dose from zoo animal foods was 0.22–7.8 μg/kg bw/day. • Total As concentrations in soils of zoo animal enclosures were 1.0–110 mg/kg. • Endangered zoo animals live in soils with As above USEPA Eco-SSLs for avian and mammal species. • Dislodgeable As on CCA-wood beams where primates sit was 4.6–111 μg/100 cm{sup 2}. • Marmoset hair had 6.37 mg/kg As compared to a reference value of 0.21 mg/kg.

    Chloroplastic thioredoxins f and m (TRX f and TRX m) mediate light regulation of carbon metabolism through the activation of Calvin cycle enzymes. The role of TRX f and m in the activation of Calvin cycle enzymes is best known among the TRX family. However, the discoveries of new potential targets extend the functions of chloroplastic TRXs to other processes in non-photosynthetic tissues. As occurs with numerous chloroplast proteins, their expression comes under light regulation. Here, the focus is on the light regulation of TRX f and TRX m in pea and Arabidopsis during the day/night cycle that is maintained during the subjective night. In pea (Pisum sativum), TRX f and TRX m1 expression is shown to be governed by a circadian oscillation exerted at both the transcriptional and protein levels. Binding shift assays indicate that this control probably involves the interaction of the CCA1 transcription factor and an evening element (EE) located in the PsTRX f and PsTRX m1 promoters. In Arabidopsis, among the multigene family of TRX f and TRX m, AtTRX f2 and AtTRX m2 mRNA showed similar circadian oscillatory regulation, suggesting that such regulation is conserved in plants. However, this oscillation was disrupted in plants overexpressing CCA1 (cca1-ox) or repressing CCA1 and LHY (cca1-lhy). The physiological role of the oscillatory regulation of chloroplastic TRX f and TRX m in plants during the day/night cycle is discussed.

    Young adults experience faster weight gain and consume more unhealthy food than any other age groups. The impact of online food marketing on "digital native" young adults is unclear. This study examined the effects of online marketing on young adults' consumption behaviours, using energy drinks as a case example. The elaboration likelihood model of persuasion was used as the theoretical basis. A pre-test post-test experimental research design was adopted using mixed-methods. Participants (aged 18-24) were randomly assigned to control or experimental groups (N = 30 each). Experimental group participants' attitudes towards and intended purchase and consumption of energy drinks were examined via surveys and semi-structured interviews after their exposure to two popular energy drink brands' websites and social media sites (exposure time 8 minutes). Exposure to digital marketing contents of energy drinks improved the experimental group participants' attitudes towards and purchase and consumption intention of energy drinks. This study indicates the influential power of unhealthy online marketing on cognitively mature young adults. This study draws public health attentions to young adults, who to date have been less of a focus of researchers but are influenced by online food advertising.

    2009-09-01

    Multidimensional fuzzy set ordination (MFSO) is an ordination algorithm based on the principles of fuzzy set theory that employs a dissimilarity matrix and environmental or experimental variables directly in the calculation of ordination coordinates. The objective is similar to constrained ordinations such as canonical correspondence analysis (CCA) and distance-based redundancy analysis (DB-RDA), although MFSO employs a different conceptual and algorithmic basis. Results from MFSO, CCA, and DB-RDA are compared on four data sets to determine the relative ability of the methods to identify and quantify environmental variable effect sizes on community variability. Models were fit by best all-subsets solutions and tested for significance by permutation tests. Methods were compared on the basis of variables selected and dimensionality of results and were evaluated on the basis of the correlation of the pair-wise distances of the derived ordination solutions to a Bray-Curtis dissimilarity matrix of the taxon data, and by cross-comparisons of the inertia explained by the fitted or derived values substituted into DB-RDA and CCA analyses. MFSO and DB-RDA achieved the highest correlation with the Bray-Curtis dissimilarity matrix on one data set each, and they tied for highest correlation on the two other data sets (differences set, tied for second on another, and achieved the lowest correlation on two data sets. When substituting MFSO- and DB-RDA-derived values into CCA, MFSO results achieved higher inertia explained on two of the four data sets; MFSO and DB-RDA achieved equivalent results on the other two. Substituting MFSO- or CCA-derived or fitted values into DB-RDA, MFSO results achieved higher inertia explained on all four data sets. While goodness-of-fit statistics were often similar across methods, the methods sometimes chose solutions of different dimensionality or employed different variables. In general, all algorithms performed well, finding relatively low

  19. Advancing Coordination Between DRM and CCA in Integrated Flood Risk Management

    DEFF Research Database (Denmark)

    Flood hazards in coastal regions induce risks toward lives, property, economy and the environment. In need of sustainable and holistic actions to reduce risks, these should include innovative Disaster Risk Management (DRM) and Climate Change Adaptation (CCA) measures. While differing on important...... parameters such as political commitment, awareness and uncertainty of the hazard/risk, commonalities between DRM and CCA can also be identified that affect human settlement, institutional adaptation, and the economy. This supports coordination of mitigation and adaptation measures to create resilience...... and sustainable solutions that take into account present and future outcomes. Adaptation must be integrated in existing policy making and be a planning process priority to become effective, however. In relation to coastal hazards in Denmark, deficits are identified in how DRM is brought into effect, e.g. though...

    Function AutoBiplot.CCA was built in R language. Given two multivariate data sets, this function carries out a conventional canonical correlation analysis, followed by the automatic production of predictive biplots based on the accuracy of readings as assessed by a mean standard predictive error and a user defined tolerance value. As the user's intervention is mainly restricted to the choice of the magnitude of the t.axis value, common misinterpretations, overestimations and adjustments between outputs and personal beliefs are avoided.

    2012-01-01

    Full Text Available Background : Smile is a crucial factor in creating a good first impression. However conditions like dental fluorosis hamper the esthetics of teeth. This study was conducted to find out whether young adults attribute socially relevant characteristics to people with dental fluorosis. Materials and Methods : A total of 150 young adults were presented with images of individuals with different severity levels of dental fluorosis along with images of normal tooth appearance on a computer screen. They had to attribute various socially relevant characteristics to these images. Images were digitally manipulated to simulate dental fluorosis. Images were displayed on a computer screen and Visual Basic Software was used to record the participants′ responses as well as the time taken to respond. The time taken to respond or response latency indicates the response strength. Statistical analysis : A chi-square test was used to test the association between the dental appearances and the socially relevant characteristics. A Mann--Whitney test was used to compare the time taken to respond. Results : As the severity of fluorosis increases, participants attribute less and less of positive characteristics. Attribution of negative characteristics also increases with the severity of dental fluorosis. For images with moderate and severe fluorosis, respondents took more time to accept positive characteristics and less time to reject positive characteristic. This means that the participants felt strongly when rejecting positive characteristics in these images. Conclusion : Social judgments are made by young adults when viewing digitally manipulated images of different levels of fluorosis.

    Full Text Available In a multi-receiver encryption system, a sender chooses a set of authorized receivers and sends them a message securely and efficiently, as the message is well encrypted and only one ciphertext corresponding to the message is generated no matter how many receivers the sender has chosen. It can be applied to video conferencing systems, pay-per-view channels, remote education, and so forth. Due to privacy considerations, an authorized receiver may not expect that his identity is revealed. In 2010, anonymous multi-receiver identity-based (ID-based encryption was first discussed, and furthermore, many works on the topic have been presented so far. Unfortunately, we find that all of those schemes fail to prove the chosen ciphertext attacks (CCA security in either confidentiality or anonymity. In this manuscript, we propose the first anonymous multi-receiver ID-based authenticated encryption scheme with CCA security in both confidentiality and anonymity. In the proposed scheme, the identity of the sender of a ciphertext can be authenticated by the receivers after a successful decryption. In addition, the proposed scheme also is the first CCA-secure one against insider attacks. Moreover, only one pairing computation is required in decryption.

  7. Neuropsychological and socio-occupational functioning in young psychiatric outpatients: a longitudinal investigation.

    Directory of Open Access Journals (Sweden)

    Rico S C Lee

    Full Text Available BACKGROUND: Clinical symptoms and neuropsychological deficits are longitudinally associated with functional outcome in chronic psychiatric cohorts. The current study extended these findings to young and early-course psychiatric outpatients, with the aim of identifying cognitive markers that predict later socio-occupational functioning. METHODS: At baseline, 183 young psychiatric outpatients were assessed. Ninety-three returned for follow-up (M = 21.6 years old; SD = 4.5 with an average re-assessment interval of 21.6 months (SD = 7.0, and primary diagnoses of major depressive disorder (n = 34, bipolar disorder (n = 29, or psychosis (n = 30. The primary outcome measure was cross-validated with various other functional measures and structural equation modelling was used to map out the interrelationships between predictors and later functional outcome. RESULTS: Good socio-occupational functioning at follow-up was associated with better quality of life, less disability, current employment and being in a romantic relationship. The final structural equation model explained 47.5% of the variability in functional outcome at follow-up, with baseline neuropsychological functioning (a composite of memory, working memory and attentional switching the best independent predictor of later functional outcome. Notably, depressive and negative symptoms were only associated with functioning cross-sectionally. Diagnosis at follow-up was not associated with functional outcome. CONCLUSIONS: Neuropsychological functioning was the single best predictor of later socio-occupational outcome among young psychiatric outpatients. Therefore, framing psychiatric disorders along a neuropsychological continuum is likely to be more useful in predicting functional trajectory than traditional symptom-based classification systems. The current findings also have implications for early intervention utilising cognitive remediation approaches.

    This longitudinal study examined normative beliefs about aggression (e.g., face-to-face, cyber) in relation to the engagement in cyber aggression 6 months later among 126 (69 women) young adults. Participants completed electronically administered measures assessing their normative beliefs, face-to-face and cyber aggression at Time 1, and cyber aggression 6 months later (Time 2). We found that men reported more cyber relational and verbal aggression when compared to women. After controlling for each other, Time 1 face-to-face relational aggression was positively related to Time 2 cyber relational aggression, whereas Time 1 face-to-face verbal aggression was positively related to Time 2 cyber verbal aggression. Normative beliefs regarding cyber aggression was positively related to both forms of cyber aggression 6 months later, after controlling for normative beliefs about face-to-face aggression. Furthermore, a significant two-way interaction between Time 1 cyber relational aggression and normative beliefs about cyber relational aggression was found. Follow-up analysis showed that Time 1 cyber relational aggression was more strongly related to Time 2 cyber relational aggression when young adults held higher normative beliefs about cyber relational aggression. A similar two-way interaction was found for cyber verbal aggression such that the association between Time 1 and Time 2 cyber verbal aggression was stronger at higher levels of normative beliefs about cyber verbal aggression. Results are discussed in terms of the social cognitive and behavioral mechanisms associated with the engagement of cyber aggression.

    Streptomyces clavuligerus ATCC 27064 and S. clavuligerus ΔccaR::tsr cultures were grown in asparagine-starch medium, and samples were taken in the exponential and stationary growth phases. Transcriptomic analysis showed that the expression of 186 genes was altered in the ccaR-deleted mutant. These genes belong to the cephamycin C gene cluster, clavulanic acid gene cluster, clavams, holomycin, differentiation, carbon, nitrogen, amino acids or phosphate metabolism and energy production. All the clavulanic acid biosynthesis genes showed Mc values in the order of -4.23. The blip gene-encoding a β-lactamase inhibitory protein was also controlled by the cephamycin C-clavulanic acid cluster regulator (Mc -2.54). The expression of the cephamycin C biosynthesis genes was greatly reduced in the mutant (Mc values up to -7.1), while the genes involved in putative β-lactam resistance were less affected (Mc average -0.88). Genes for holomycin biosynthesis were upregulated. In addition, the lack of clavulanic acid and cephamycin production negatively affected the expression of genes for the clavulanic acid precursor arginine and of miscellaneous genes involved in nitrogen metabolism (amtB, glnB, glnA3, glnA2, glnA1). The transcriptomic results were validated by quantative reverse transcription polymerase chain reaction and luciferase assay of luxAB-coupled promoters. Transcriptomic analysis of the homologous genes of S. coelicolor validated the results obtained for S. clavuligerus primary metabolism genes.

    Background The Kato-Katz is the most common diagnostic method for Schistosoma mansoni infection. However, the day-to-day variability in host egg-excretion and its low detection sensitivity are major limits for its use in low transmission zones and after widespread chemotherapy. We evaluated the accuracy of circulating cathodic antigen (CCA) urine-assay as a diagnostic tool of S. mansoni. In comparison, a low sensitive CCA test (CCA-L) was assessed. Methodology The study was conducted in three settings: two foci with single S. mansoni infections (settings A and B), and one mixed S. mansoni – S. haematobium focus (setting C). Stool and urine samples were collected from school-children on three consecutive days. Triplicate Kato-Katz readings were performed per stool sample. Each urine sample was tested with one CCA and only the first urine sample was subjected to CCA-L. Urine samples were also examined for S. haematobium eggs using the filtration method and for microhaematuria using urine reagent strips. Overall, 625 children provided three stool and three urine samples. Principal Findings Considering nine Kato-Katz thick smears as ‘reference’ diagnostic test, the prevalence of S. mansoni was 36.2%, 71.8% and 64.0% in settings A, B and C, respectively. The prevalence of S. haematobium in setting C was 12.0%. The sensitivities of single Kato-Katz, CCA and CCA-L from the first stool or urine samples were 58%, 82% and 46% in setting A, 56.8%, 82.4% and 68.8% in setting B, and 49.0%, 87.7% and 55.5% in setting C. The respective specificities were 100%, 64.7% and 100%; 100%, 62.3% and 91.3%; and 100%, 42.5% and 92.0%. Mixed infection with S. haematobium did not influence the CCA test results for S. mansoni diagnosis.

    Full Text Available BACKGROUND: The Kato-Katz is the most common diagnostic method for Schistosoma mansoni infection. However, the day-to-day variability in host egg-excretion and its low detection sensitivity are major limits for its use in low transmission zones and after widespread chemotherapy. We evaluated the accuracy of circulating cathodic antigen (CCA urine-assay as a diagnostic tool of S. mansoni. In comparison, a low sensitive CCA test (CCA-L was assessed. METHODOLOGY: THE STUDY WAS CONDUCTED IN THREE SETTINGS: two foci with single S. mansoni infections (settings A and B, and one mixed S. mansoni - S. haematobium focus (setting C. Stool and urine samples were collected from school-children on three consecutive days. Triplicate Kato-Katz readings were performed per stool sample. Each urine sample was tested with one CCA and only the first urine sample was subjected to CCA-L. Urine samples were also examined for S. haematobium eggs using the filtration method and for microhaematuria using urine reagent strips. Overall, 625 children provided three stool and three urine samples. PRINCIPAL FINDINGS: Considering nine Kato-Katz thick smears as 'reference' diagnostic test, the prevalence of S. mansoni was 36.2%, 71.8% and 64.0% in settings A, B and C, respectively. The prevalence of S. haematobium in setting C was 12.0%. The sensitivities of single Kato-Katz, CCA and CCA-L from the first stool or urine samples were 58%, 82% and 46% in setting A, 56.8%, 82.4% and 68.8% in setting B, and 49.0%, 87.7% and 55.5% in setting C. The respective specificities were 100%, 64.7% and 100%; 100%, 62.3% and 91.3%; and 100%, 42.5% and 92.0%. Mixed infection with S. haematobium did not influence the CCA test results for S. mansoni diagnosis. CONCLUSIONS/SIGNIFICANCE: Urine CCA revealed higher sensitivity than CCA-L and triplicate Kato-Katz, and produced similar prevalence as nine Kato-Katz. It seems an attractive method for S. mansoni diagnosis.

    Full Text Available The paper analyzed children’s perceptions of teasing within their real world peer relationships through participants’ drawings and accompanying narratives. The case study research was approached from an ethic of listening to children to discover and uncover children’s perceptions and experiences with the phenomenon of peer teasing. Fifteen children from kindergarten to grade 2 participated in drawing and narrating their complex understandings of the multi-faceted aspects of peer teasing. The participants attended two30-40 minute sessions of conversational interviews with the first session also involving drawing and narrating personal stories of teasing. The results of the study indicate the significance of teasing within the young peer relationship as well as several distinct perceptions and insights. Ultimately, these insights may help teachers to broaden curricular approaches within the school culture and enhance current theoretical conceptualizations of peer teasing.

    Chemical pesticide treatment enables relatively nonresistant woods to be used in outdoor construction projects. The most prevalent procedure used to protect these woods is pressure treatment with chromium, copper, and arsenic (CCA). This pilot study examined the airborne concentration and particle size distribution of wood particles, chromium, copper, and arsenic at both outdoor (measured over the whole work day) and indoor (measured during the performance of specific tasks) work sites. At the outdoor residential deck construction sites, the arithmetic mean total dust concentration, measured using personal filter cassette samplers, was 0.57 mg/m3. The mass median aerodynamic diameter (da) of the outdoor wood dust was greater than 20 microm. Indoor wood dust concentrations were significantly greater than those measured outdoor and were job category-dependent. The highest mean breathing zone dust concentration, 49.0 mg/m3, was measured at the indoor sanding operation. Personal impactor sampling demonstrated that the mean total airborne concentration of arsenic, but not chromium or copper, was consistently above recommended occupational exposure levels at the indoor work site, and occasionally at the outdoor work sites. At the indoor sanding operation, the mean total chromium, copper, and arsenic concentrations were 345, 170, and 342 microg/m3, respectively. Thus, significant exposure to airborne heavy metals can occur as a result of indoor and outdoor exposure to CCA pressure-treated wood dust. Therefore, current standards for wood dust may not adequately protect workers from the heavy metals commonly used in CCA pressure-treated wood.

    Full Text Available Growth in executive functioning (EF skills play a role children's academic success, and the transition to elementary school is an important time for the development of these abilities. Despite this, evidence concerning the development of the ERP components linked to EF, including the error-related negativity (ERN and the error positivity (Pe, over this period is inconclusive. Data were recorded in a school setting from 3- to 7-year-old children (N = 96, mean age = 5 years 11 months as they performed a Go/No-Go task. Results revealed the presence of the ERN and Pe on error relative to correct trials at all age levels. Older children showed increased response inhibition as evidenced by faster, more accurate responses. Although developmental changes in the ERN were not identified, the Pe increased with age. In addition, girls made fewer mistakes and showed elevated Pe amplitudes relative to boys. Based on a representative school-based sample, findings indicate that the ERN is present in children as young as 3, and that development can be seen in the Pe between ages 3 and 7. Results varied as a function of gender, providing insight into the range of factors associated with developmental changes in the complex relations between behavioral and electrophysiological measures of error processing.

    Full Text Available Food services are basic services of the tourism offer. Unlike the other elements of the tourism product sold to a visitor, the offer of food units target to a high extent the residents. The habit to satisfy the need of food & beverage in specialized units, concept known under the name of “dining-out”, records in Romania a lower spread in comparison with developed states. This situation is determined by the low level of incomes, the lack of the lunch break with a duration of at least one hour in the working program of many companies which could favor serving the meal in a food unit, etc, but also the concern of the restaurants to satisfy the demand for events (weddings, baptisms, etc or satisfying the needs of socialization and amusement of population during evenings. The article aims to highlight the opinions and attitudes of young consumers from Romania regarding the food service consumption, the elements which determine the decision to eat in a restaurant and the issues that might favor this action.

    Deficits in social functioning are a core feature of autistic spectrum disorders (ASD), being linked to various cognitive and developmental factors, but there has been little attempt to draw on normative models of social cognition to understand social behaviour in ASD. The current study explored the utility of Crick and Dodge's (1994) information processing model to studying social cognition in ASD, and examined associations between social information processing patterns, theory of mind skills and social functioning. A matched-group design compared young people with Asperger syndrome with typically developing peers, using a social information processing interview previously designed for this purpose. The Asperger syndrome group showed significantly different patterns of information processing at the intent attribution, response generation and response evaluation stages of the information processing model. Theory of mind skills were found to be significantly associated with parental ratings of peer problems in the Asperger syndrome group but not with parental ratings of pro-social behaviour, with only limited evidence of an association between social information processing and measures of theory of mind and social functioning. Overall, the study supports the use of normative social information processing approaches to understanding social functioning in ASD.

    Full Text Available This project examined the lifestyle, health habits and risk factors of young adults at Qatar University. It explored the clustering and differences in dietary habits, body mass index (BMI and physical activity (PA amongst male and female students, both Qatari and non-Qatari. Seven hundred thirty two students aged 18–25 years completed a self-reported questionnaire and an objective measure of BMI. Males and females had a high prevalence of being overweight and obesity and low levels of PA, according to well-established international standards. Three clusters were identified based on the students’ lifestyle and dietary habits. Cluster 1 (high risk factors included those who engaged the least in healthy dietary practices and consumed the most unhealthy foods, participated in less PA and had the highest BMI. Cluster 2 (moderate risk factors included those with considerably more habits falling into the moderate category, engagement in the most PA, the least TV and computer viewing time and had the lowest BMI. Cluster 3 (low risk factors included those who engaged the most with the four healthy dietary practices, the least with the four unhealthy dietary practices and participated in moderate PA per week. This project provides valuable data that could be used by policy makers to address issues concerning student’s health.

    Violence in the physical (offline) world is a well-documented health and social issue among young people worldwide. In Southeast Asia, online harassment (defined as intentional behaviours to harm others through the Internet or through mobile devices) is less well documented. In this paper, we describe and critically discuss the mixed-methods data collection approach we used to build a contextualised understanding of offline violence and online harassment among 15- to 24-year-old students and out-of-school youth in Central Thailand. We mapped linkages between offline violence and online harassment, and with their possible correlates including gender, sexuality, and mobile media or Internet use. Data collection methods included in-depth interviews, focus group discussions and a custom-built, self-administered computerised survey. Using mixed methods enabled us to collect holistic qualitative/quantitative data from both students and out-of-school youth. In our discussion, we focus on gender, sexuality, class and ethnicity issues in recruiting out-of-school youth; definition and measurement issues; technical issues in using a computerised survey; ethical issues surrounding data collection from minors as well as privacy and confidentiality concerns in collecting data in both in-school and out-of-school settings; and the general implications of using mixed methods.

    Full Text Available http://dx.doi.org/10.5902/198050989292This study aimed to evaluate the retention and penetration of copper chrome arsenate (CCA type C as well as some wood properties of two rotations of two natural hybrid of Eucalyptus urophylla S. T. Blake, aiming their use as treated wood. The study was conducted with material from commercial plantations, with 63 months of age. For the wood characterization, the relationship sapwood-heartwood, the basic density and the size of fibers and vessels were evaluated. For the evaluation of treated wood, the penetration and retention of copper chrome arsenate (CCA type C were determined. Four trees per rotation and genetic material were used, which subsequently were split into three logs, in a total of 12 logs for each treatment. The preservative treatment was performed using the full cell process in autoclave using CCA solution with 2% concentration of active ingredients. The treatment process used was effective under the conditions required by the NBR 9480, with retention values ​​higher than the minimum required by the standard, which is 6.5 kg/m3 of CCA per treated wood, and in addition, provided deep penetration and regular condom in sapwood of all timber treated. There are no restrictions on the use of wood from the first and second rotation for preservative treatment, based on the properties evaluated. There was no correlation between the type C CCA retention and wood properties evaluated.

    In this paper, we describe the architecture and performance of the GraCCA system, a graphic-card cluster for astrophysics simulations. It consists of 16 nodes, with each node equipped with two modern graphic cards, the NVIDIA GeForce 8800 GTX. This computing cluster provides a theoretical performance of 16.2 TFLOPS. To demonstrate its performance in astrophysics computation, we have implemented a parallel direct N-body simulation program with shared time-step algorithm in this system. Our system achieves a measured performance of 7.1 TFLOPS and a parallel efficiency of 90% for simulating a globular cluster of 1024 K particles. In comparing with the GRAPE-6A cluster at RIT (Rochester Institute of Technology), the GraCCA system achieves a more than twice higher measured speed and an even higher performance-per-dollar ratio. Moreover, our system can handle up to 320M particles and can serve as a general-purpose computing cluster for a wide range of astrophysics problems.

    RT-PCR analysis of the genes in the clavulanic acid cluster revealed three transcriptional polycistronic units that comprised the ceaS2-bls2-pah2-cas2, cyp-fd-orf12-orf13 and oppA2-orf16 genes, whereas oat2, car, oppA1, claR, orf14, gcaS and pbpA were expressed as monocistronic transcripts. Quantitative RT-PCR of Streptomyces clavuligerus ATCC 27064 and the mutant S. clavuligerus ccaR::aph showed that, in the mutant, there was a 1000- to 10,000-fold lower transcript level for the ceaS2 to cas2 polycistronic transcript that encoded CeaS2, the first enzyme of the clavulanic acid pathway that commits arginine to clavulanic acid biosynthesis. Smaller decreases in expression were observed in the ccaR mutant for other genes in the cluster. Two-dimensional electrophoresis and MALDI-TOF analysis confirmed the absence in the mutant strain of proteins CeaS2, Bls2, Pah2 and Car that are required for clavulanic acid biosynthesis, and CefF and IPNS that are required for cephamycin biosynthesis. Gel shift electrophoresis using recombinant r-CcaR protein showed that it bound to the ceaS2 and claR promoter regions in the clavulanic acid cluster, and to the lat, cefF, cefD-cmcI and ccaR promoter regions in the cephamycin C gene cluster. Footprinting experiments indicated that triple heptameric conserved sequences were protected by r-CcaR, and allowed identification of heptameric sequences as CcaR binding sites.

    Full Text Available A total of 206 urine samples collected from Hassoba Elementary schoolchildren, Afar, Ethiopia, a low Schistosoma haematobium endemic setting, was diagnosed to evaluate the performance of CCA strip using double references, urine filtration technique and urinalysis dipstick (Combur 10 Test® that detect schistosome eggs and blood in urine, respectively. The former was used as a gold standard reference method. Sensitivity, specificity, positive and negative predictive values for the CCA were 52%, 63.8%, 56.7% and 59% respectively, with reference to urine filtration technique whereas these parameters were 50.4%, 62.4%, 55.6% and 57.5% respectively, with reference to Combur 10 Test®. 47 S. haematobium egg-positive children were found negative by CCA strip while 38 egg-negative children were found positive by CCA strip. Moreover, among the pre-tests done in duplicate, inconsistent results were also recorded. Assays were also compared with regard to the cost of equipment and reagents, speed and simplicity of use. Though CCA strip was found to be rapid and could be performed with minimal training, it was found to be expensive (US $ 4.95 per test to use it for large-scale field use even if its diagnostic value would have been satisfactory. Further development and standardization of the CCA strip are required for its applicability for field use. It is also recommended that its cost per strip should be substantially cut down if it is to be used in poor schistosomiasis endemic countries.

    High levels of occupational stress and burnout are costly for correctional services and their employees. Correctional officers report high levels of burnout, absenteeism, turnover, and poor physical health. The purpose of this study was to investigate the prevalence of burnout and the coping mechanisms used to buffer the effects of burnout within correctional centers. In the current study, 208 correctional officers from adult and young offender centers completed an online survey measuring burnout and coping strategies. Results from the Maslach Burnout Inventory-Human Services Survey (MBI-HSS) and the Brief Coping Orientation to Problems Experienced (COPE) Scale indicated that even though correctional center officers mostly used adaptive coping strategies, they still reported high levels of burnout. The results of this study suggest that there are variables other than coping strategies, such as gender and length of experience, that lead to the level of burnout as observed in correctional officers.

    In this work, a 3D MCTS-CCA system was constructed by culturing multi-cellular tumor spheroid (MCTS) in the chitosan/collagen/alginate (CCA) fibrous scaffold for anticancer drug screening. The CCA scaffolds were fabricated by spray-spinning. The interactions between the components of the spray-spun fibers were evidenced by methods of Coomassie Blue stain, X-ray diffraction (XRD) and Fourier transform-infrared spectroscopy (FTIR). Co-culture indicated that MCF-7 cells showed a spatial growth pattern of multi-cellular tumor spheroid (MCTS) in the CCA fibrous scaffold with increased proliferation rate and drug-resistance to MMC, ADM and 5-Aza comparing with the 2D culture cells. Significant increases of total viable cells were found in 3D MCTS groups after drug administration by method of apoptotic analysis. Glucose–lactate analysis indicated that the metabolism of MCTS in CCA scaffold was closer to the tumor issue in vivo than the monolayer cells. In addition, MCTS showed the characteristic of epithelial mesenchymal transition (EMT) which is subverted by carcinoma cells to facilitate metastatic spread. These results demonstrated that MCTS in CCA scaffold possessed a more conservative phenotype of tumor than monolayer cells, and anticancer drug screening in 3D MCTS-CCA system might be superior to the 2D culture system. - Highlights: • Chitosan/collagen/alginate (CCA) scaffolds were fabricated by spray-spinning. • MCF-7 cells presented a multi-cellular tumor spheroid model (MCTS) in CCA scaffold. • MCTS in CCA possessed a more conservative phenotype of tumor than monolayer cells. • Anticancer drug screening in MCTS-CCA system is superior to 2D culture system.

    Background Promising results have been reported for a urine circulating cathodic antigen (CCA) test for the diagnosis of Schistosoma mansoni. We assessed the accuracy of a commercially available CCA cassette test (designated CCA-A) and an experimental formulation (CCA-B) for S. mansoni diagnosis. Methodology We conducted a cross-sectional survey in three settings of Côte d'Ivoire: settings A and B are endemic for S. mansoni, whereas S. haematobium co-exists in setting C. Overall, 446 children, aged 8–12 years, submitted multiple stool and urine samples. For S. mansoni diagnosis, stool samples were examined with triplicate Kato-Katz, whereas urine samples were tested with CCA-A. The first stool and urine samples were additionally subjected to an ether-concentration technique and CCA-B, respectively. Urine samples were examined for S. haematobium using a filtration method, and for microhematuria using Hemastix dipsticks. Principal Findings Considering nine Kato-Katz as diagnostic ‘gold’ standard, the prevalence of S. mansoni in setting A, B and C was 32.9%, 53.1% and 91.8%, respectively. The sensitivity of triplicate Kato-Katz from the first stool and a single CCA-A test was 47.9% and 56.3% (setting A), 73.9% and 69.6% (setting B), and 94.2% and 89.6% (setting C). The respective sensitivity of a single CCA-B was 10.4%, 29.9% and 75.0%. The ether-concentration technique showed a low sensitivity for S. mansoni diagnosis (8.3–41.0%). The specificity of CCA-A was moderate (76.9–84.2%); CCA-B was high (96.7–100%). The likelihood of a CCA-A color reaction increased with higher S. mansoni fecal egg counts (odds ratio: 1.07, p<0.001). A concurrent S. haematobium infection or the presence of microhematuria did not influence the CCA-A test results for S. mansoni diagnosis. Conclusion/Significance CCA-A showed similar sensitivity than triplicate Kato-Katz for S. mansoni diagnosis with no cross-reactivity to S. haematobium and microhematuria. The low sensitivity of

    Linear predictive models are applied to functional MRI (fMRI) data to estimate boundaries that predict experimental task states for scans. These boundaries are visualized as statistical parametric maps (SPMs) and range from low to high spatial reproducibility across subjects (e.g., Strother , 2004; LaConte , 2003). Such inter-subject pattern reproducibility is an essential characteristic of interpretable SPMs that generalize across subjects. Therefore, we introduce a flexible hybrid model that optimizes reproducibility by simultaneously enhancing the prediction power and reproducibility. This hybrid model is formed by a weighted summation of the optimization functions of a linear discriminate analysis (LDA) model and a generalized canonical correlation (gCCA) model (Afshin-Pour , 2012). LDA preserves the model's ability to discriminate the fMRI scans of multiple brain states while gCCA finds a linear combination for each subject's scans such that the estimated boundary map is reproducible. The hybrid model is implemented in a split-half resampling framework (Strother , 2010) which provides reproducibility (r) and prediction (p) quality metrics. Then the model was compared with LDA, and Gaussian Naive Bayes (GNB). For simulated fMRI data, the hybrid model outperforms the other two techniques in terms of receiver operating characteristic (ROC) curves, particularly for detecting less predictable but spatially reproducible networks. These techniques were applied to real fMRI data to estimate the maps for two task contrasts. Our results indicate that compared to LDA and GNB, the hybrid model can provide maps with large increases in reproducibility for small reductions in prediction, which are jointly closer to the ideal performance point of (p=1, r=1).

    Full Text Available Purpose: This paper describes methodological procedures involving execution of a large-scale, multi-site longitudinal study of language and reading comprehension in young children. Researchers in the Language and Reading Research Consortium (LARRC developed and implemented these procedures to ensure data integrity across multiple sites, schools, and grades. Specifically, major features of our approach, as well as lessons learned, are summarized in ten steps essential for successful completion of a large-scale longitudinal investigation in early grades. Method: Over five years, children in preschool through third grade were administered a battery of 35 higher- and lower-level language, listening, and reading comprehension measures. Data were collected from children, their teachers, and their parents/guardians at four sites across the United States. Substantial and rigorous effort was aimed toward maintaining consistency in processes and data management across sites for children, assessors, and staff. Conclusion: With appropriate planning, flexibility, and communication strategies in place, LARRC developed and executed a successful multi-site longitudinal research study that will meet its goal of investigating the contribution and role of language skills in the development of children’s listening and reading comprehension. Through dissemination of our design strategies and lessons learned, research teams embarking on similar endeavors can be better equipped to anticipate the challenges.

    Removal of Cu and Cr from chromated copper arsenate (CCA)-treated wood waste under batch electrodialytic conditions was studied. The effect of different types of extracting solutions, such as deionised water or aqueous solutions of NaCl, formic acid, oxalic acid, and EDTA, on the magnitude...... and direction of the fluxes of Cu- and Cr-containing species in the electrodialytic cell was investigated. Oxalic acid was found to have the best performance if simultaneous removal of the two elements is required (removal efficiencies of 80.5% for Cu and 87.4% for Cr, respectively). A mixture of oxalic acid....... The latter were not present if EDTA was the extracting solution resulting in directing the Cu and Cr fluxes to the anode compartment. Contrary, these fluxes were exclusively to the cathode compartment if deionised water or an aqueous solution of NaCl were used. These extracting solutions proved suitable...

    Multimodal fusion is an effective approach to better understand brain diseases. However, most such instances have been limited to pair-wise fusion; because there are often more than two imaging modalities available per subject, there is a need for approaches that can combine multiple datasets optimally. In this paper, we extended our previous two-way fusion model called "multimodal CCA+joint ICA", to three or N-way fusion, that enables robust identification of correspondence among N data types and allows one to investigate the important question of whether certain disease risk factors are shared or distinct across multiple modalities. We compared "mCCA+jICA" with its alternatives in a 3-way fusion simulation and verified its advantages in both decomposition accuracy and modal linkage detection. We also applied it to real functional Magnetic Resonance Imaging (fMRI)-Diffusion Tensor Imaging (DTI) and structural MRI fusion to elucidate the abnormal architecture underlying schizophrenia (n=97) relative to healthy controls (n=116). Both modality-common and modality-unique abnormal regions were identified in schizophrenia. Specifically, the visual cortex in fMRI, the anterior thalamic radiation (ATR) and forceps minor in DTI, and the parietal lobule, cuneus and thalamus in sMRI were linked and discriminated between patients and controls. One fMRI component with regions of activity in motor cortex and superior temporal gyrus individually discriminated schizophrenia from controls. Finally, three components showed significant correlation with duration of illness (DOI), suggesting that lower gray matter volumes in parietal, frontal, and temporal lobes and cerebellum are associated with increased DOI, along with white matter disruption in ATR and cortico-spinal tracts. Findings suggest that the identified fractional anisotropy changes may relate to the corresponding functional/structural changes in the brain that are thought to play a role in the clinical expression of

  17. Evaluation of the CCA Immuno-Chromatographic Test to Diagnose Schistosoma mansoni in Minas Gerais State, Brazil.

    Full Text Available The Kato-Katz (KK stool smear is the standard test for the diagnosis of Schistosoma mansoni infection, but suffers from low sensitivity when infections intensities are moderate to low. Thus, misdiagnosed individuals remain untreated and contribute to the disease transmission, thereby forestalling public health efforts to move from a modality of disease control to one of elimination. As an alternative, the urine-based diagnosis of schistosomiasis mansoni via the circulating cathodic antigen immuno-chromatographic test (CCA-ICT has been extensively evaluated in Africa with the conclusion that it may replace the KK test in areas where prevalences are moderate or high.The objective was to measure the performance of the CCA-ICT in a sample study population composed of residents from non-endemic and endemic areas for schistosomiasis mansoni in two municipalities of Minas Gerais state, Brazil. Volunteers (130 were classified into three infection status groups based on duplicate Kato-Katz thick smears from one stool sample (2KK test: 41 negative individuals from non-endemic areas, 41 negative individuals from endemic areas and 48 infected individuals from endemic areas. Infection status was also determined by the CCA-ICT and infection exposure by antibody ELISA (enzyme-linked immunosorbent assay to S. mansoni soluble egg antigen (SEA and soluble (adult worm antigen preparation (SWAP. Sensitivity and specificity were influenced by whether the trace score visually adjudicated in the CCA-ICT was characterized as positive or negative for S. mansoni infection. An analysis of a two-graph receiver operating characteristic was performed to change the cutoff point. When the trace score was interpreted as a positive rather than as a negative result, the specificity decreased from 97.6% to 78.0% whereas sensitivity increased from 68.7% to 85.4%. A significantly positive correlation between the CCA-ICT scores and egg counts was identified (r = 0.6252, p = 0

    Lumber treated with chromated copper arsenate (CCA) has been used in residential outdoor wood structures and playgrounds. The U.S. EPA has conducted a probabilistic assessment of children's exposure to arsenic from CCA-treated structures using the Stochastic Human Exposure and Dose Simulation model for the wood preservative scenario (SHEDS-Wood). The EPA assessment relied on data from an experimental study using adult volunteers and designed to measure arsenic in maximum hand and wipe loadings. Analyses using arsenic handloading data from a study of children playing on CCA-treated play structures in Edmonton, Canada, indicate that the maximum handloading values significantly overestimate the exposure that occurs during actual play. The objective of our paper is to assess whether the dislodgeable arsenic residues from structures in the Edmonton study are comparable to those observed in other studies and whether they support the conclusion that the values derived by EPA using modeled maximum loading values overestimate hand exposures. We compared dislodgeable arsenic residue data from structures in the playgrounds in the Edmonton study to levels observed in studies used in EPA's assessment. Our analysis showed that the dislodgeable arsenic levels in the Edmonton playground structures are similar to those in the studies used by EPA. Hence, the exposure estimates derived using the handloading data from children playing on CCA-treated structures are more representative of children's actual exposures than the overestimates derived by EPA using modeled maximum values. Handloading data from children playing on CCA-treated structures should be used to reduce the uncertainty of modeled estimates derived using the SHEDS-Wood model.

    Context. Very low-mass (VLM) stars and brown dwarfs (BDs) present a different rotational behaviour from their solar mass counter-parts. Aims. We investigate the rotational evolution of young VLM stars and BDs using Monte Carlo simulations under the hypothesis of disk locking and stellar angular momentum conservation. Methods. We built a set of objects with masses ranging from 0.01 Mo to 0.4 Mo and considered models with single- and double- peaked initial period distributions with and without disk locking. An object is considered to be diskless when its mass accretion rate is below a given threshold. Results. Models with initial single-peaked period distributions reproduce the observations well given that BDs rotate faster than VLM stars. We observe a correlation between rotational period and mass when we relax the disk locking hypothesis, but with a shallower slope compared to some observational results. The angular momentum evolution of diskless stars is flatter than it is for stars with a disk which occurs ...

    The Twins Early Development Study (TEDS) is a large longitudinal sample of twins born in England and Wales between 1994 and 1996. The focus of TEDS has been on cognitive and behavioral development, including difficulties in the context of normal development. TEDS began when multiple births were identified from birth records and the families were invited to take part in the study; 16,810 pairs of twins were originally enrolled in TEDS. More than 10,000 of these twin pairs remain enrolled in the study to date. DNA has been collected for more than 7,000 pairs, and genome-wide genotyping data for two million DNA markers are available for 3,500 individuals. The TEDS families have taken part in studies when the twins were aged 2, 3, 4, 7, 8, 9, 10, 12, 14, and 16 years of age. Data collection is currently underway to assess the adult destinations of the twins as they move from school to university and the workplace. Between January 2012 and December 2014, all of the TEDS twins will turn 18, and the study will transition to an adult sample. TEDS represents an outstanding resource for investigating the developmental effects of genes and environments on complex quantitative traits from childhood to young adulthood and beyond.

    It has been shown that music might be able to improve mood state in people affected by psychiatric disorders, ameliorate cognitive deficits in people with dementia and increase motor coordination in Parkinson patients. Robust experimental evidence explaining the central effects of music, however, is missing. This study was designed to investigate the effect of music on brain neurotrophin production and behavior in the mouse. We exposed young adult mice to music with a slow rhythm (6 h/day; mild sound pressure levels, between 50 and 60 db) for 21 consecutive days. At the end of the treatment, mice were tested for passive avoidance learning and then killed for analysis of brain-derived neurotrophic factor (BDNF) and nerve growth factor with enzyme-linked immunosorbent assay (ELISA) in selected brain regions. We found that music-exposed mice showed increased BDNF, but not nerve growth factor in the hippocampus. Furthermore, we observed that music exposure significantly enhanced learning performance, as measured by the passive avoidance test. Our results demonstrate that exposure to music can modulate the activity of the hippocampus by influencing BDNF production. Our findings also suggest that music exposure might be of help in several central nervous system pathologies.

    Context. The low spin rates measured for solar-type stars at an age of a few Myr ( 10% of the break-up velocity) indicate that some mechanism of angular momentum regulation must be at play in the early pre-main sequence. This may be associated with magnetospheric accretion and star-disk interaction, as suggested by observations that disk-bearing objects (CTTS) are slower rotators than diskless sources (WTTS) in young star clusters. Aims: We characterize the rotation properties for members of the star-forming region NGC 2264 ( 3 Myr) as a function of mass, and investigate the accretion-rotation connection at an age where about 50% of the stars have already lost their disks. Methods: We examined a sample of 500 cluster members (40% with disks, 60% without disks), distributed in mass between 0.15 and 2 M⊙, whose photometric variations were monitored in the optical for 38 consecutive days with the CoRoT space observatory. Light curves were analyzed for periodicity using three different techniques: the Lomb-Scargle periodogram, the autocorrelation function and the string-length method. Periods were searched in the range between 0.17 days (i.e., 4 h, twice the data sampling adopted) and 19 days (half the total time span). Period detections were confirmed using a variety of statistical tools (false alarm probability, Q-statistics), as well as visual inspection of the direct and phase-folded light curves. Results: About 62% of sources in our sample were found to be periodic; the period detection rate is 70% among WTTS and 58% among CTTS. The vast majority of periodic sources exhibit rotational periods shorter than 13 d. The period distribution obtained for the cluster consists of a smooth distribution centered around P = 5.2 d with two peaks, located respectively at P = 1-2 d and at P = 3-4 d. A separate analysis of the rotation properties for CTTS and WTTS indicates that the P = 1-2 d peak is associated with the latter, while both groups contribute to the P = 3-4 d peak

    In this work, a 3D MCTS-CCA system was constructed by culturing multi-cellular tumor spheroid (MCTS) in the chitosan/collagen/alginate (CCA) fibrous scaffold for anticancer drug screening. The CCA scaffolds were fabricated by spray-spinning. The interactions between the components of the spray-spun fibers were evidenced by methods of Coomassie Blue stain, X-ray diffraction (XRD) and Fourier transform-infrared spectroscopy (FTIR). Co-culture indicated that MCF-7 cells showed a spatial growth pattern of multi-cellular tumor spheroid (MCTS) in the CCA fibrous scaffold with increased proliferation rate and drug-resistance to MMC, ADM and 5-Aza comparing with the 2D culture cells. Significant increases of total viable cells were found in 3D MCTS groups after drug administration by method of apoptotic analysis. Glucose-lactate analysis indicated that the metabolism of MCTS in CCA scaffold was closer to the tumor issue in vivo than the monolayer cells. In addition, MCTS showed the characteristic of epithelial mesenchymal transition (EMT) which is subverted by carcinoma cells to facilitate metastatic spread. These results demonstrated that MCTS in CCA scaffold possessed a more conservative phenotype of tumor than monolayer cells, and anticancer drug screening in 3D MCTS-CCA system might be superior to the 2D culture system.

    2001-01-01

    The relations between lake surface sediment diatoms and water environmental variables were revealed effectively by use of a new multivariate canonical correspondence analysis (CCA) based on 45 lakes in the Tibetan Plateau. Water depth, conductivity, Cl-, Mg2+, K+ and pH, identified from 12 contemporary water environmental variables, can significantly and independently explain the diatom distributions (p<0.05). The first two axes (λ1=0.34, λ2=0.27) capture 16.1% of the variance in the species data, and account for 57.4% of the variance in diatom-environment relationship. The deletion of redundant environmental variables and unusual samples do not influence the explanation to diatom data. The final CCA result indicates that the water depth and the salinity are the two important environmental gradients and influence the diatom distribution in the plateau lakes. The water depth correlates with axis 1, while conductivity, Cl-, Mg2+ and K+, indicating the direction of salinity changes, corr

    Current research applying variability measures of gait parameters has demonstrated promise for helping to solve one of the "holy grails" of geriatric research by defining markers that can be used to prospectively identify persons at risk of falling . The minimum toe clearance (MTC) event occurs during the leg swing phase of the gait cycle and is a task highly sensitive to the spatial and balance control properties of the locomotor system. The aim of this study is to build upon the current state of research by investigating the magnitude and dynamic structure from the MTC time series fluctuations due to aging and locomotor disorder. Thirty healthy young (HY), 27 healthy elderly (HE), and 10 falls risk (FR) elderly individuals (who presented a prior history of trip-related falls) participated in treadmill walking for at least 10 min at their preferred speed. Continuous MTC data were collected and the first 512 data points were analyzed. The following variability indices were quantified: 1) MTC mean and standard deviation (SD), 2) PoincarE plot indices of MTC variability (SD1, SD2, SD1/SD2), 3) a wavelet based multiscale exponent beta to describe the dynamic structure of MTC fluctuations, and 4) detrended fluctuation analysis exponent alpha to investigate the presence of long-range correlations in MTC time series data. Results showed that stride-to-stride MTC time series has a nonlinear structure in all three groups when compared against randomly shuffled surrogate MTC data. Test on aging effects showed the MTC central tendency was significantly lower (p 0.05). There were, however, significant differences between HY and FR for beta (between scale 1 and 2; p < 0.01) and alpha (p < 0.05). Out of all the variability measures applied, beta(Wv2-4), SD1/SD2, SD2 of critical MTC parameter were found to be potential markers to be able to reliably identify FR from HE subjects. Further research is required to understand the mechanisms underlying the cause of MTC variability.

    Zumba is a ∼2.9 km diameter rayed crater on Mars located on extensive lava plains in Daedalia Planum to the southwest of Arsia Mons. It is a well-preserved young crater with large ejecta rays that extend for hundreds of kilometers from the impact site. The rays are thermally distinct from the background lava flows in THEMIS daytime and nighttime thermal infrared data, a unique characteristic among martian rayed craters. Concentrated within the rays are solitary or dense clusters of secondary craters with associated diffuse dark-toned deposits along with fewer secondary craters lacking dark-toned deposits. Using CTX images, we have mapped secondary craters with dark-toned deposits, collectively termed "secondary fields", to investigate their distribution as a function of distance from the impact site. The mapped secondary field was then used to investigate various aspects of the crater-forming event such as the surface angle and direction of the projectile, the effect of secondary craters on surface age estimates, and the number of secondary craters produced by the impact event. From our mapping, a total of 13,064 secondary fields were documented out to a 200 km radial distance beyond a 15 km-wide non-secondary zone around Zumba crater. Results show that the highest areal coverage of secondary fields occurs within 100 km of Zumba and within its rays, decreasing radially with distance to a background scattering of small secondary fields that are moderately oblique impact projectile coming from the south. Using primary craters in a ∼101 km2 sample region and all craters (primaries and secondaries) from 43 select secondary fields in two map sectors in the study area, we obtain ages of ∼580 ± 100 Ma and ∼650 ± 70 Ma, respectively, for the lava flows into which Zumba impacted. These ages are consistent with and intermediate to 0.1-1 Ga volcanic flow units within and near Daedalia Planum. For craters within the secondary fields, a log differential plot of the

    Brazil produces around 1,2 mi m{sup 3} of treated wood to meet the annual demand of railway, electric, rural and construction sectors. The treated woods used for poles, sleepers, fence posts and plywoods should be according to Brazilian norms requirements. The most used wood species are eucalyptus (Eucaliptus ssp)and pine (Pinus ssp). The most wood preservative products used in Brazil are CCA (Chromated Copper Arsenate) and CCB (Copper Chromium and Boron Salt). The analytical methods, such as Flame Atomic Absorption Spectrometry (FAAS) and Plasma Inductively Coupled Optical Emission Spectrometry (ICPOES) have been used for the evaluation of those treatment processes. In this work, the sapwood sample was obtained from eucalyptus trees (Eucaliptus ssp) obtained from Minas Gerais State, Brazil, cut plantation areas. Sawdust sapwood sample was grounded and submitted to different additions of CCA solutions (0.2, 0.7, 1.3, 2.3, 3.6, 6.3, 11.7and17.9 kg m{sup -3}). Power and pressed pellets sapwood samples, analyzed by EDXRFS, showed a good linear relation (r{sup 2}>0.99) between the characteristic intensity fluorescent lines (CuΚα, CrΚαand AsΚΒ) and their concentration, also, showed adequate sensitivity (LQ < 5mgkg{sup -1}) for Cu, Cr and As determination in treated woods. Cu, Cr and As were determined in powdered sawdust samples by FAA spectrometry, using the AWPA A11-93 standard method; the relation between the CCA retention and their concentration showed a lower linear relation than EDXRFS; the FAAS spreading result could be attributed to laboratorial CCA addition process.

    Full Text Available Abstract For disease surveillance and mapping within large-scale control programmes, RDTs are becoming popular. For intestinal schistosomiasis, a commercially available urine-dipstick which detects schistosome circulating cathodic antigen (CCA in host urine is being increasingly applied, however, further validation is needed. In this study, we compared the CCA urine-dipstick test against double thick Kato-Katz faecal smears from 171 schoolchildren examined along the Tanzanian and Kenyan shorelines of Lake Victoria. Diagnostic methods were in broad agreement; the mean prevalence of intestinal schistosomiasis inferred by Kato-Katz examination was 68.6% (95% confidence intervals (CIs = 60.7-75.7% and 71.3% (95% CIs = 63.9-78.8% by CCA urine-dipsticks. There were, however, difficulties in precisely 'calling' the CCA test result, particularly in discrimination of 'trace' reactions as either putative infection positive or putative infection negative, which has important bearing upon estimation of mean infection prevalence; considering 'trace' as infection positive mean prevalence was 94.2% (95% CIs = 89.5-97.2%. A positive association between increasing intensity of the CCA urine-dipstick test band and faecal egg count was observed. Assigning trace reactions as putative infection negative, overall diagnostic sensitivity (SS of the CCA urine-dipstick was 87.7% (95% CIs = 80.6-93.0%, specificity (SP was 68.1% (95% CIs = 54.3-80.0%, positive predictive value (PPV was 86.1% (95% CIs = 78.8-91.7% and negative predictive value (NPV was 71.1% (95% CIs = 57.2-82.8%. To assist in objective defining of the CCA urine-dipstick result, we propose the use of a simple colour chart and conclude that the CCA urine-dipstick is a satisfactory alternative, or supplement, to Kato-Katz examination for rapid detection of intestinal schistosomiasis.

Diagnostic methods were in broad agreement; the mean prevalence of intestinal schistosomiasis inferred by Kato-Katz examination was 68.6% (95% confidence intervals (CIs) = 60.7-75.7%) and 71.3% (95% CIs = 63.9-78.8%) by CCA urine-dipsticks. There were, however, difficulties in precisely 'calling' the CCA test result, particularly in discrimination of 'trace' reactions as either putative infection positive or putative infection negative, which has important bearing upon estimation of mean infection prevalence; considering 'trace' as infection positive mean prevalence was 94.2% (95% CIs = 89.5-97.2%). A positive association between increasing intensity of the CCA urine-dipstick test band and faecal egg count was observed. Assigning trace reactions as putative infection negative, overall diagnostic sensitivity (SS) of the CCA urine-dipstick was 87.7% (95% CIs = 80.6-93.0%), specificity (SP) was 68.1% (95% CIs = 54.3-80.0%), positive predictive value (PPV) was 86.1% (95% CIs = 78.8-91.7%) and negative predictive value (NPV) was 71.1% (95% CIs = 57.2-82.8%). To assist in objective defining of the CCA urine-dipstick result, we propose the use of a simple colour chart and conclude that the CCA urine-dipstick is a satisfactory alternative, or supplement, to Kato-Katz examination for rapid detection of intestinal schistosomiasis.

    This work deals with the possible application of a portable energy dispersive handmade system (PXRF-LFNA-02) for the determination of Chromium, Copper and Arsenic in the preservative solution used to protect commercial wood of Eucalyptus, which are employed as wood fence, posts, contention fences, railroad sleepers, etc. It was prepared five body-of-proof made of eucalyptus alburnum with different concentrations for each element varying from 0.0061 to 0.0180 (g/g) for CrO{sub 3}, 0.0024 to 0.0070 (g/g) for CuO and 0.0044 to 0.0129 (g/g) for As{sub 2}O{sub 5}. Four of them were used for calibration curves and one used as reference sample. It was used a commercial CCA (Chromated Copper Arsenate ) solution to prepare the samples. The results show a good linear regression between concentrations and X-rays intensities, after applied the multiple linear regression methodology for interelemental corrections. The values obtained with this methodology were 3.01(kg/m{sup 3}), 1.18 (kg/m{sup 3}) e 2.21 (kg/m{sup 3}) for CrO{sub 3}, CuO and As{sub 2}O{sub 5}, respectively, while the nominal values are 2.90 (kg/m{sup 3}) for CrO{sub 3}, 1.13 (kg/m{sup 3}) for CuO and 2.07 (kg/m{sup 3}) for As{sub 2}O{sub 5}. The ED-XRF (Energy Dispersive X-Rays Fluorescence) is a well established technique with high-speed of analytical procedure and its portable configuration allowing a multielemental, simultaneous and non destructive analyses besides in situ application.

    Full Text Available Abstract Background The Mood and Anxiety Symptom Questionnaire (MASQ was designed to specifically measure the Tripartite model of affect and is proposed to offer a delineation between the core components of anxiety and depression. Factor analytic data from adult clinical samples has shown mixed results; however no studies employing confirmatory factor analysis (CFA have supported the predicted structure of distinct Depression, Anxiety and General Distress factors. The Tripartite model has not been validated in a clinical sample of older adolescents and young adults. The aim of the present study was to examine the validity of the Tripartite model using scale-level data from the MASQ and correlational and confirmatory factor analysis techniques. Methods 137 young people (M = 17.78, SD = 2.63 referred to a specialist mental health service for adolescents and young adults completed the MASQ and diagnostic interview. Results All MASQ scales were highly inter-correlated, with the lowest correlation between the depression- and anxiety-specific scales (r = .59. This pattern of correlations was observed for all participants rating for an Axis-I disorder but not for participants without a current disorder (r = .18. Confirmatory factor analyses were conducted to evaluate the model fit of a number of solutions. The predicted Tripartite structure was not supported. A 2-factor model demonstrated superior model fit and parsimony compared to 1- or 3-factor models. These broad factors represented Depression and Anxiety and were highly correlated (r = .88. Conclusion The present data lend support to the notion that the Tripartite model does not adequately explain the relationship between anxiety and depression in all clinical populations. Indeed, in the present study this model was found to be inappropriate for a help-seeking community sample of older adolescents and young adults.

    Full Text Available Abstract Background Anaemia is an important problem amongst young children living in rural India. However, there has not previously been a detailed study of the biological aetiology of this anaemia, exploring the relative contributions of iron, vitamin B12, folate and Vitamin A deficiency, inflammation, genetic haemoglobinopathy, hookworm and malaria. Nor have studies related these aetiologic biological factors to household food security, standard of living and child feeding practices. Barriers to conducting such work have included perceived reluctance of village communities to permit their children to undergo venipuncture, and logistical issues. We have successfully completed a community based, cross sectional field study exploring in detail the causes of anaemia amongst young children in a rural setting. Methods and design A cross sectional, community based study. We engaged in extensive community consultation and tailored our study design to the outcomes of these discussions. We utilised local women as field workers, harnessing the capacity of local health workers to assist with the study. We adopted a programmatic approach with a census rather than random sampling strategy in the village, incorporating appropriate case management for children identified to have anaemia. We developed a questionnaire based on existing standard measurement tools for standard of living, food security and nutrition. Specimen processing was conducted at the Primary Health Centre laboratory prior to transport to an urban research laboratory. Discussion Adopting this study design, we have recruited 415 of 470 potentially eligible children who were living in the selected villages. We achieved support from the community and cooperation of local health workers. Our results will improve the understanding into anaemia amongst young children in rural India. However, many further studies are required to understand the health problems of the population of rural India, and

  20. "...they should be offering it": a qualitative study to investigate young peoples' attitudes towards chlamydia screening in GP surgeries

    Full Text Available Abstract Background Despite the known health and healthcare costs of untreated chlamydia infection and the efforts of the National Chlamydia Screening Programme (NCSP to control chlamydia through early detection and treatment of asymptomatic infection, the rates of screening are well below the 2010-2011 target rate of 35%. General Practitioner (GP surgeries are a key venue within the NCSP however; previous studies indicate that GP surgery staff are concerned that they may offend their patients by offering a screen. This study aimed to identify the attitudes to, and preferences for, chlamydia screening in 15-24 year old men and women attending GP surgeries (the target group. Methods We undertook 36 interviews in six surgeries of differing screening rates. Our participants were 15-24 year olds attending a consultation with a staff member. Data were analysed thematically. Results GP surgeries are acceptable to young people as a venue for opportunistic chlamydia screening and furthermore they think it is the duty of GP surgery staff to offer it. They felt strongly that it is important for surgery staff to have a non-judgemental attitude and they did not want to be singled out as 'needing' a chlamydia screen. Furthermore, our sample reported a strong preference for being offered a screen by staff and providing the sample immediately at the surgery rather than taking home a testing kit. The positive attitude and subjective norms demonstrated by interviewees suggest that young peoples' behaviour would be to accept a screen if it was offered to them. Conclusion Young people attending GP surgeries have a positive attitude towards chlamydia screening and given the right environment are likely to take up the offer in this setting. The right environment involves normalising screening by offering a chlamydia screen to all 15-24 year olds at every interaction with staff, offering screening with a non-judgemental attitude and minimising barriers to screening

    Collection of multiple-task brain imaging data from the same subject has now become common practice in medical imaging studies. In this paper, we propose a simple yet effective model, "CCA+ICA", as a powerful tool for multi-task data fusion. This joint blind source separation (BSS) model takes advantage of two multivariate methods: canonical correlation analysis and independent component analysis, to achieve both high estimation accuracy and to provide the correct connection between two datasets in which sources can have either common or distinct between-dataset correlation. In both simulated and real fMRI applications, we compare the proposed scheme with other joint BSS models and examine the different modeling assumptions. The contrast images of two tasks: sensorimotor (SM) and Sternberg working memory (SB), derived from a general linear model (GLM), were chosen to contribute real multi-task fMRI data, both of which were collected from 50 schizophrenia patients and 50 healthy controls. When examining the relationship with duration of illness, CCA+ICA revealed a significant negative correlation with temporal lobe activation. Furthermore, CCA+ICA located sensorimotor cortex as the group-discriminative regions for both tasks and identified the superior temporal gyrus in SM and prefrontal cortex in SB as task-specific group-discriminative brain networks. In summary, we compared the new approach to some competitive methods with different assumptions, and found consistent results regarding each of their hypotheses on connecting the two tasks. Such an approach fills a gap in existing multivariate methods for identifying biomarkers from brain imaging data.

    Young's double-slit experiment is one of the most historically significant works in physics, and one that is easily done in an introductory physics class. It is also an excellent example of an investigation that allows us to infer the nature of phenomena beyond direct observation. Unfortunately, perhaps because of this, it is often also an excellent example of the problem with canned cookbook labs. Students dutifully go through the physical motions of the investigation and can easily get good measurements. But actual intellectual engagement is missing. This paper details an instructional sequence that allows an authentic, student-centered approach to this historic investigation. Key to the approach is creating the context in which students can meaningfully devise an investigation into light's wave character.

    This study investigated an HIV prevention program for homeless young adult injection drug users (IDUs) that combined a secondary syringe exchange program (SEP) with community-level activities. Homeless young IDUs were recruited from street-based settings in San Francisco, and a structured questionnaire was administered. The secondary SEP operated in a circumscribed geographic area, and for analytic purposes respondents were assigned to the intervention site group if they primarily spent time in this area (n = 67), or the comparison site group if they primarily spent time elsewhere (n = 55). Almost all (96%) intervention site youth had used the secondary SEP in the past 30 days and were significantly more likely to regularly use SEP. In bivariate analysis, comparison site IDUs were more likely to share syringes, reuse syringes, share the cotton used to filter drugs, and use condoms with casual sex partners only inconsistently. In multivariate analysis, comparison site remained positively associated with sharing syringes (adjusted odds ratio [AOR], 3.748; 95% confidence interval [CI], 1.406-9.988), reusing syringes (AOR, 2.769; 95% CI,1.120-6.847), and inconsistent condom use with casual sex partners (AOR, 4.825; 95% CI, 1.392- 16.721). This suggests that the intervention was effective in delivering SEP services to homeless young adult IDUs, and that IDUs who frequented the intervention site had a lower HIV risk than comparison group IDUs.

    Substantial evidence links greater impulsivity and stress exposure to poorer smoking cessation outcomes. Results from adolescents also indicate that stress-related change in risk taking can impede cessation attempts. We investigated the effects of stress-related change in impulsivity, risk taking, attention and nicotine withdrawal, and craving in young adult smokers on time to smoking relapse in a relapse analogue paradigm. Twenty-six young adult smokers (50% women; mean age: 20.9 ± 1.8) were exposed to a stress imagery session followed by a contingency management-based relapse analogue paradigm. Participants smoked at least 5 cigarettes daily, with a mean baseline carbon monoxide (CO) level of 13.7 (± 5.1) ppm. Repeated measures analysis of variance (ANOVA) and paired t tests examined stress induction validity and Cox regressions of proportional hazards examined the effects of stress-related changes in nicotine withdrawal, nicotine craving, attention, impulsivity, and risk taking on time to relapse. While stress-related change in impulsivity, nicotine craving and withdrawal did not predict time to relapse (all ps > .10), greater stress-related increases in reaction time (RT) variability (p = .02) were predictive of shorter time to relapse, with trend-level findings for inattention and risk taking. Furthermore, changes in stress-related risk taking affected outcome in women more than in men, with a significant relationship between stress-related change in risk taking only in women (p = .026). Smoking cessation attempts in young adults may be adversely impacted by stress-related increases in risk taking and attentional disruption. Clinicians working with young adults attempting cessation may need to target these stress-related impairments by fostering more adaptive coping and resilience.

  5. Effect of post treatment temperature and humidity conditions on fixation performance of CCA-C treated red pine and southern pine

    Institute of Scientific and Technical Information of China (English)

    1999-01-01

    Rates of fixation in chromated copper arsenate (CCA-C) treated red pine (Pinus resinosa Ait.) and southern pine (Pinus spp) sapwood specimens using retention of 1.5, 2.0, 6.4 kg·m-3 are compared at temperature (T) ranging from 70 ℃ to 50 ℃ and 5 different relative humidity (RH) conditions. The samples were investigated using the expressate method to follow chromium fixation. Red pine fixes faster than southern pine under all 11 post treatment schedules. The fixation rates for both species are not significantly different while the blocks were fixed under 6 fixation/drying schedules that differed only in the order of T/RH conditions applied. The rate of fixation of all samples in any fixation stage were reduced when the blocks were fixed under lower humidity conditions in spite of no change in chamber temperature. Some of this influence can be attributed to the effect of humidity on heat transfer into the wood and cooling of the wood surface.

    There is emerging evidence for talking therapies in the treatment of tic disorders. This study explored experiences of young people who self-identified as having had a successful or helpful talking therapy, in order to understand the phenomenology, value and meaning of outcomes. The experiences of seven participants aged 10-17 years were described in semi-structured interviews and analysed using Interpretative Phenomenological Analysis. Themes included the challenging battle with tics and process of re-defining self-identity, making sense of and managing experiences, the value of control, and spectrum of positive change. The results highlighted valued outcomes that could be incorporated into clinical practice and future evaluation.

    The Chartherm process (Thermya, Bordeaux, France) is a thermochemical conversion process to treat chromated copper arsenate (CCA) impregnated wood waste. The process aims at maximum energy valorization and material recuperation by combining the principles of low-temperature slow pyrolysis and distillation in a smart way. The main objective of the exergy analysis presented in this paper is to find the critical points in the Chartherm process where it is necessary to apply some measures in order to reduce exergy consumption and to make energy use more economic and efficient. It is found that the process efficiency can be increased with 2.3-4.2% by using the heat lost by the reactor, implementing a combined heat and power (CHP) system, or recuperating the waste heat from the exhaust gases to preheat the product gas. Furthermore, a comparison between the exergetic performances of a 'chartherisation' reactor and an idealized gasification reactor shows that both reactors destroy about the same amount of exergy (i.e. 3500kWkg(wood)(-1)) during thermochemical conversion of CCA-treated wood. However, the Chartherm process possesses additional capabilities with respect to arsenic and tar treatment, as well as the extra benefit of recuperating materials.

    In this pilot study, we examine molecular jets from the embedded Class I sources, HH 26 and HH 72, to search, for the first time, for kinematic signatures of jet rotation from young embedded sources.High resolution long-slit spectroscopy of the H2 1-0 S(1) transition was obtained using VLT/ISAAC, position-velocity (PV) diagrams constructed and intensity-weighted radial velocities transverse to the jet flow measured. Mean intensity-weighted velocities vary between vLSR ~ -90 and -65 km/s for HH 26, and -60 and -10 km/s for HH 72; maxima occur close to the intensity peak and decrease toward the jet borders. Velocity dispersions are ~ 45 and ~ 80 km/s for HH 26 and HH 72, respectively, with gas motions as fast as -100 km/s present. Asymmetric PV diagrams are seen for both objects which a simple empirical model of a cylindrical jet section shows could in principle be reproduced by jet rotation alone. Assuming magneto-centrifugal launching, the observed HH 26 flow may originate at a disk radius of 2-4 AU from the ...

  11. The multiple truths about crystal meth among young people entrenched in an urban drug scene: a longitudinal ethnographic investigation.

    2014-06-01

    Transitions into more harmful forms of illicit drug use among youth have been identified as important foci for research and intervention. In settings around the world, the transition to crystal methamphetamine (meth) use among youth is considered a particularly dangerous and growing problem. Epidemiological evidence suggests that, particularly among young, street-involved populations, meth use is associated with numerous sex- and drug-related "risks behaviors" and negative health outcomes. Relatively few studies, however, have documented how youth themselves understand, experience and script meth use over time. From 2008 to 2012, we conducted over 100 in-depth interviews with 75 street-entrenched youth in Vancouver, Canada, as well as ongoing ethnographic fieldwork, in order to examine youth's understandings and experiences of meth use in the context of an urban drug scene. Our findings revealed positive understandings and experiences of meth in relation to other forms of drug addiction and unaddressed mental health issues. Youth were simultaneously aware of the numerous health-related harms and social costs associated with heavy meth use. Over time, positive understandings of meth may become entirely contradictory to a lived reality in which escalating meth use is a factor in further marginalizing youth, although this may not lead to cessation of use. Recognition of these multiple truths about meth, and the social structural contexts that shape the scripting of meth use among youth in particular settings, may help us to move beyond moralizing debates about how to best educate youth on the "risks" associated with meth, and towards interventions that are congruent with youth's lived experiences and needs across the lifecourse.

    Full Text Available Abstract Background Muscle strength is important for young people with Down syndrome as they make the transition to adulthood, because their workplace activities typically emphasise physical rather than cognitive skills. Muscle strength is reduced up to 50% in people with Down syndrome compared to their peers without disability. Progressive resistance training improves muscle strength and endurance in people with Down syndrome. However, there is no evidence on whether it has an effect on work task performance or physical activity levels. The aim of this study is to investigate if a student-led community-based progressive resistance training programme can improve these outcomes in adolescents and young adults with Down syndrome. Methods A randomised controlled trial will compare progressive resistance training with a control group undertaking a social programme. Seventy adolescents and young adults with Down syndrome aged 14-22 years and mild to moderate intellectual disability will be randomly allocated to the intervention or control group using a concealed method. The intervention group will complete a 10-week, twice a week, student-led progressive resistance training programme at a local community gymnasium. The student mentors will be undergraduate physiotherapy students. The control group will complete an arts/social programme with a student mentor once a week for 90 minutes also for 10 weeks to control for the social aspect of the intervention.

    Full Text Available The intrinsic purpose of this study was to investigate empirically that how young consumers’ intention to buy the counterfeited fashion products is empowered by selected personality traits, such as fashion consciousness, public self-consciousness, ethical obligation and ethical judgment. The research was carried out on a sample of N = 269 respondents of different age groups and gender. Data for this study were collected by using a structured questionnaire containing six tiers, where Section-I contains seven statements using Likert scale, to assay the consumers’ degree of fashion consciousness. Section-II deals with the questions related to the consumers’ degree of public self consciousness. Section-III and IV contains two and three statements respectively to measure the consumers’ degree of ethical obligation and ethical judgment. Two items were used in Section-V to measure the consumers’ intention to buy the fashion counterfeits in the future. Questions related to the consumers’ demographical profile were asked in Section-VI. One-Way ANOVA was employed to test the proposed hypothesis. To determine among which groups the true differences prevail, the Duncan Multiple Range Test was performed. It was disclosed that the young consumers with high level of fashion consciousness and public self consciousness are more interested in buying the counterfeited fashion products. On the ethical grounds, it was divulged that the consumers who think it as an unethical practice to buy the counterfeited products are less likely to buy the counterfeited brands.

    2010-11-01

    Full Text Available Circadian rhythms are daily biological oscillations driven by an endogenous mechanism known as circadian clock. The protein kinase CK2 is one of the few clock components that is evolutionary conserved among different taxonomic groups. CK2 regulates the stability and nuclear localization of essential clock proteins in mammals, fungi, and insects. Two CK2 regulatory subunits, CKB3 and CKB4, have been also linked with the Arabidopsis thaliana circadian system. However, the biological relevance and the precise mechanisms of CK2 function within the plant clockwork are not known. By using ChIP and Double-ChIP experiments together with in vivo luminescence assays at different temperatures, we were able to identify a temperature-dependent function for CK2 modulating circadian period length. Our study uncovers a previously unpredicted mechanism for CK2 antagonizing the key clock regulator CIRCADIAN CLOCK-ASSOCIATED 1 (CCA1. CK2 activity does not alter protein accumulation or subcellular localization but interferes with CCA1 binding affinity to the promoters of the oscillator genes. High temperatures enhance the CCA1 binding activity, which is precisely counterbalanced by the CK2 opposing function. Altering this balance by over-expression, mutation, or pharmacological inhibition affects the temperature compensation profile, providing a mechanism by which plants regulate circadian period at changing temperatures. Therefore, our study establishes a new model demonstrating that two opposing and temperature-dependent activities (CCA1-CK2 are essential for clock temperature compensation in Arabidopsis.

    Diagnosis of schistosomiasis at the point-of-care (POC) is a growing topic in neglected tropical disease research. There is a need for diagnostic tests which are affordable, sensitive, specific, user-friendly, rapid, equipment-free and delivered to those who need it, and POC is an important tool for disease mapping and guiding mass deworming. The aim of present study was to evaluate the relative diagnostic performance of two urine-circulating cathodic antigen (CCA) cassette assays, one commercially available and the other in experimental production, against results obtained using the standard Kato-Katz faecal smear method (six thick smears from three consecutive days), as a 'gold-standard', for Schistosoma mansoni infection in different transmission settings in Uganda. Our study was conducted among 500 school children randomly selected across 5 schools within Bugiri district, adjacent to Lake Victoria in Uganda. Considering results from the 469 pupils who provided three stool samples for the six Kato-Katz smears, 293 (76%) children had no infection, 109 (23%) were in the light intensity category, while 42 (9%) and 25 (5%) were in the moderate and heavy intensity categories respectively. Following performance analysis of CCA tests in terms of sensitivity, specificity, negative and positive predictive values, overall performance of the commercially available CCA test was more informative than single Kato-Katz faecal smear microscopy, the current operational field standard for disease mapping. The current CCA assay is therefore a satisfactory method for surveillance of S. mansoni in an area where disease endemicity is declining due to control interventions. With the recent resolution on schistosomiasis elimination by the 65th World Health Assembly, the urine POC CCA test is an attractive tool to augment and perhaps replace the Kato-Katz sampling within ongoing control programmes.

    提出了一种新颖的基于典型相关分析(CCA)的模糊判别分析方法(fuzzy-LDA/CCA),并应用于面部表情识别问题.首先为每幅表情图像建立一个相关联的类模糊隶属度矢量,用于表示表情图像与基本表情类别的隶属关系,在此基础上应用CCA方法建立表情图像同表情类别的关系表达式,最后通过对表情图像的类隶属度矢量的估计来实现表情的分类.此外,还将fuzzy-LDA/CCA方法在核空间中进行了非线性推广,从而来解决非线性判别分析的问题.实验证明提出的方法获得了更好的识别效果.%A novel fuzzy linear discriminant analysis method by the canonical correlation analysis (fuzzy-LDA/CCA)is presented and applied to the facial expression recognition. The fuzzy method is used to evaluate the degree of the class membership to which each training sample belongs. CCA is then used to establish the relationship between each facial image and the corresponding class membership vector, and the class membership vector of a test image is estimated using this relationship. Moreover, the fuzzy-LDA/CCA method is also generalized to deal with nonlinear discriminant analysis problems via kernel method. The performance of the proposed method is demonstrated using real data.

    Full Text Available Previous research suggests that bilinguals demonstrate superior cognitive control processes than monolinguals. The goal of the current investigation was to examine whether this bilingual advantage is observed in a language processing task that requires inhibition, i.e., lexical ambiguity processing. Monolingual and bilingual participants read sentences that biased the reading of a terminal homonym toward the subordinate or dominant reading (e.g., The doctor asked her to step onto the scale.. A relatedness judgement was made on target words that were related to the contextually appropriate (e.g., balance or inappropriate meaning (e.g., skin, or unrelated to either meaning (e.g., shoe while electrophysiological recording took place. The results revealed subtle processing differences between monolinguals and bilinguals that were evident in electrophysiological measures, but not in behavioural measures. These findings suggest that monolinguals rely on context to access the contextually appropriate meaning of a homonym to a greater extent than bilinguals, while bilinguals demonstrate simultaneous activation of both meanings.

    The low spin rates measured for solar-type stars at an age of a few Myr (~10% of the break-up velocity) indicate that some mechanism of angular momentum regulation must be at play in the early pre-main sequence. We characterize the rotation properties for members of the region NGC 2264 (~3 Myr), and investigate the accretion-rotation connection at an age where about 50% of the stars have already lost their disks. We examined a sample of 500 cluster members whose photometric variations were monitored in the optical for 38 consecutive days with CoRoT. Light curves were analyzed for periodicity using the Lomb-Scargle periodogram, the autocorrelation function and the string-length method. The period distribution obtained for the cluster consists of a smooth distribution centered around P=5.2 d with two peaks at P=1-2 d and 3-4 d. A separate analysis of CTTS and WTTS indicates that the P=1-2 d peak is associated with the latter, while both groups contribute to the P=3-4 d peak. The comparison between CTTS and WTTS...

    Children's early onset of social anxiety may be associated with their social understanding, and their ability to express emotions adaptively. We examined whether social anxiety in 48-month-old children (N = 110; 54 boys) was related to: a) a lower level of theory of mind (ToM); b) a lower proclivity to express shyness in a positive way (adaptive); and c) a higher tendency to express shyness in a negative way (non-adaptive). In addition, we investigated to what extent children's level of social anxiety was predicted by the interaction between ToM and expressions of shyness. Children's positive and negative expressions of shyness were observed during a performance task. ToM was measured with a validated battery, and social anxiety was assessed using both parents' reports on questionnaires. Socially anxious children had a lower level of ToM, and displayed more negative and less positive shy expressions. However, children with a lower level of ToM who expressed more positive shyness were less socially anxious. Additional results show that children who displayed shyness only in a negative manner were more socially anxious than children who expressed shyness only in a positive way and children who did not display any shyness. Moreover, children who displayed both positive and negative expressions of shyness were more socially anxious than children who displayed shyness only in a positive way. These findings highlight the importance of ToM development and socio-emotional strategies, and their interaction, on the early development of social anxiety.

    Winegrape growing in many parts of the world, including Marlborough, New Zealand, uses treated-timber posts to act as supports for the grapevine's canopy. At a density of 580 posts per hectare, the H4-process treated supports result in an areal loading of CCA of: Copper (12 kg-Cu ha-1), Chromium (21 kg-Cr ha-1) and Arsenic (17 kg-As ha-1). Arsenic is the most mobile and toxic of the CCA-treatment cocktail. We describe experiments which indicate that about 4-6 mg-As month-1 post-1 is released from the subterranean part of the post. We have used SPASMO (Soil Plant Atmosphere System Model) to predict post-to-soil leakage, as well as the pattern dynamics of leaching and exchange around the post. Locally the pattern dynamics of transport and fate are controlled by the soil's chemical characteristics and the prevailing weather. Over its 20-year lifetime, the concentration of arsenic, both that adsorbed on the soil and in the soil solution, exceeds guideline values for soils (100 mg-As kg-1) and drinking water (10 μg-As L-1). Under a regime of 5% annual replacement of posts, the spatially averaged concentration of arsenic leaching through the soil is predicted to rise to 1.25 to 1.7 times the drinking water standard, depending only slightly on the soil type. The steady value is primarily controlled by the arsenic-release rate from the post. These steady values were used in a simple hydrogeological model of the major Marlborough aquifer systems to determine whether the subterranean flow of water could dilute the descending plumes of arsenic coming from above. Except for the sluggish aquifers of the southern valleys in Marlborough, most of the aquifer systems seem capable of diluting the leachate to between one tenth and one twentieth of the drinking water standard. The upscaling of our modelling of the local pattern dynamics spanned six orders of spatial magnitude, and four orders of time dimension.

    Full Text Available Attribute-Based Signcryption (ABSC is a natural extension of Attribute-Based Encryption (ABE and Attribute-Based Signature (ABS, where one can have the message confidentiality and authenticity together. Since the signer privacy is captured in security of ABS, it is quite natural to expect that the signer privacy will also be preserved in ABSC. In this paper, first we propose an ABSC scheme which is weak existential unforgeable and IND-CCA secure in adaptive-predicates models and, achieves signer privacy. Then, by applying strongly unforgeable one-time signature (OTS, the above scheme is lifted to an ABSC scheme to attain strong existential unforgeability in adaptive-predicates model. Both the ABSC schemes are constructed on common setup, i.e the public parameters and key are same for both the encryption and signature modules. Our first construction is in the flavor of CtE&S paradigm, except one extra component that will be computed using both signature components and ciphertext components. The second proposed construction follows a new paradigm (extension of CtE&S , we call it “Commit then Encrypt and Sign then Sign” (CtE&S . The last signature is generated using a strong OTS scheme. Since, the non-repudiation is achieved by CtE&S paradigm, our systems also achieve the same.

    The circadian clock regulates the expression of an array of Arabidopsis genes such as those encoding the LIGHT-HARVESTING CHLOROPHYLL A/B (Lhcb) proteins. We have previously studied the promoters of two of these Arabidopsis genes-Lhcb1*1 and Lhcb1*3-and identified a sequence that binds the clock protein CIRCADIAN CLOCK ASSOCIATED 1 (CCA1). This sequence, designated CCAl-binding site (CBS), is necessary for phytochrome and circadian responsiveness of these genes. In close proximity to this sequence, there exists a G-box core element that has been shown to bind the bZIP transcription factor HY5 in other light-regulated plant promoters. In the present study, we examined the importance of the interaction of transcription factors binding the CBS and the G-box core element in the control of normal circadian rhythmic expression of Lhcb genes. Our results show that HY5 is able to specifically bind the G-box element in the Lhcb promoters and that CCA1 can alter the binding activity of HY5. We further show that CCA1 and HY5 can physically interact and that they can act synergistically on transcription in a yeast reporter gene assay. An absence of HY5 leads to a shorter period of Lhcb1*1 circadian expression but does not affect the circadian expression of CATALASE3 (CAT3), whose promoter lacks a G-box element. Our results suggest that interaction of the HY5 and CCA1 proteins on Lhcb promoters is necessary for normal circadian expression of the Lhcb genes.

    Background The World Health Organization now recommends the provision of praziquantel treatment to preschool-aged children infected with schistosomiasis. For intestinal schistosomiasis the current operational field diagnostic standard is examination of a thick Kato-Katz smear by microscopy prepared from a single stool specimen, and although pragmatic, this methodology has well-known shortcomings. Here, as a potential alternative, the performance of the urine circulating cathodic antigen (CCA) dipstick test was assessed in terms of disease-mapping and point-of-care diagnosis for intestinal schistosomiasis in preschool-aged children. Our manuscript reports on findings at baseline and at the end of a one-year longitudinal treatment study. Methodology/Principal Findings A total of 925 children (mean age 2.8 years) were initially recruited from six lakeshore villages representative of high, moderate and low levels of disease transmission. At baseline, all children were tested for intestinal schistosomiasis by microscopic examination of duplicate Kato-Katz smears prepared from a single stool faecal, by antigen detection with the urine CCA dipstick test and by serology with a commercially available ELISA test (as ‘gold-standard’) that measures host antibody titres to soluble egg antigens. As a point-of-care diagnosis, the urine CCA dipstick test achieved sensitivity and specificity values ranging from 52.5–63.2% and 57.7–75.6%, respectively, with faecal microscopy achieving very high specificities (>87%) but sensitivities as low as 16.7% in the low transmission setting. Conclusion/Significance The urine CCA test was shown to be more effective than faecal microscopy especially in lower transmission settings. The diagnostic performance of this test was not significantly impacted by treatment history or co-infections with other intestinal helminths. PMID:23359826

    Multi-modal fusion is an effective approach in biomedical imaging which combines multiple data types in a joint analysis and overcomes the problem that each modality provides a limited view of the brain. In this paper, we propose an exploratory fusion model, we term "mCCA+jICA", by combining two multivariate approaches: multi-set canonical correlation analysis (mCCA) and joint independent component analysis (jICA). This model can freely combine multiple, disparate data sets and explore their joint information in an accurate and effective manner, so that high decomposition accuracy and valid modal links can be achieved simultaneously. We compared mCCA+jICA with its alternatives in simulation and applied it to real fMRI-DTI-methylation data fusion, to identify brain abnormalities in schizophrenia. The results replicate previous reports and add to our understanding of the neural correlates of schizophrenia, and suggest more generally a promising approach to identify potential brain illness biomarkers.

    Full Text Available The sensitivity, specificity, positive and negative predictive values of a reagent strip test for the diagnosis of schistosomiasis mansoni by detecting circulating cathodic antigen (CCA in urine were evaluated using 184 stool and urine samples collected from schoolchildren living in relatively low endemic area of schistosomiasis mansoni in Ethiopia. A combined result of stool samples processed by Kato and formol-ether concentration methods was used as gold standard. The results showed that detection of CCA in urine using reagent strip test was slightly higher than the combined results of the stool techniques (65.2% vs 42.4%, p > 0.05 in suggesting the prevalence of the disease. The sensitivity, specificity, positive and negative predictive values of the reagent strip test were 76.9%, 43.4%, 50% and 71.9%, respectively. The result of egg counts using Kato method suggested that detection of urine CCA could be used to indicate the intensity of infection. Nevertheless, like that of stool examination, the reagent strip test was found to be less sensitive in case of light to moderate infections. About 23.1% of the study children who were excreting the eggs of the parasite were found negative by the reagent strip test. The relative insensitivity of a reagent strip test in low intensity of infection necessitates for the development of more sensitive assay that can truly discriminate schistosome-infected from non-infected individuals.

    High alloyed β-phase stabilized titanium alloys are known to provide comparable Young's modulus as that to the human bones (~30 GPa) but is marred by its high density. In the present study the low titanium alloyed compositions of binary Ti-Nb and ternary Ti-Nb-Zr alloy systems, having stable β-phase with low Young's modulus are identified using first principles density functional framework. The theoretical results suggest that the addition of Nb in Ti and Zr in Ti-Nb increases the stability of the β-phase. The β-phase in binary Ti-Nb alloys is found to be fully stabilized from 22 at.% of Nb onwards. The calculated Young's moduli of binary β-Ti-Nb alloy system are found to be lower than that of pure titanium (116 GPa). For Ti-25(at.%)Nb composition the calculated Young's modulus comes out to be ~80 GPa. In ternary Ti-Nb-Zr alloy system, the Young's modulus of Ti-25(at.%)Nb-6.25(at.%)Zr composition is calculated to be ~50 GPa. Furthermore, the directional Young's moduli of these two selected binary (Ti-25(at.%)Nb) and ternary alloy (Ti-25(at.%)Nb-6.25(at.%)Zr) compositions are found to be nearly isotropic in all crystallographic directions.

    Background Accurate diagnostic techniques for schistosomiasis are essential for prevalence determination and identification of positive patients. A point-of-care test for detecting schistosome circulating cathodic antigen (POC-CCA) has been evaluated for its accuracy in different endemic regions. This reagent strip/dipstick based assay has showed high sensitivity for individuals with high or moderate worm burden, but the interpretation of light infections is less clear, especially for trace readings. Methodology/Principal Findings We introduced a urine lyophilization step to the POC-CCA assay to improve its sensitivity and clarify the interpretation of traces. We evaluated POC-CCA sensitivity and specificity within individuals with low parasite burdens in a Brazilian endemic area where a high number of traces were detected. Patients that were positive for other helminths were also evaluated for cross reactions. In all cases, a combined parasitological diagnosis using Kato-Katz (24 slides) and Saline Gradient (1 g of feces) were used as reference. At baseline, diagnosis by POC-CCA (1–2 cassettes) showed 6% sensitivity, inaccurately predicting a low prevalence of Schistosoma mansoni infections (2 POC-CCA positives/32 egg positives). After urine lyophilization, the sensitivity was increased significantly (p < 0.05). Prevalence rates changed from 2% to 32% (27 POC-CCA positives/32 egg positives), equivalent to parasitological techniques. Most of the trace readings changed to positive after lyophilization while some negatives turned into traces. Cross reaction analysis confirmed the specificity of POC-CCA. Conclusions/Significance Trace readings cannot be primarily defined as positive or negative cases. It is critical to verify case-by-case by concentrating urine 10 fold by lyophilization for the diagnosis. Following lyophilization, persistent trace readings should be read as negatives. No trained technician is needed and cost is restricted to the cost of a

This reagent strip/dipstick based assay has showed high sensitivity for individuals with high or moderate worm burden, but the interpretation of light infections is less clear, especially for trace readings.We introduced a urine lyophilization step to the POC-CCA assay to improve its sensitivity and clarify the interpretation of traces. We evaluated POC-CCA sensitivity and specificity within individuals with low parasite burdens in a Brazilian endemic area where a high number of traces were detected. Patients that were positive for other helminths were also evaluated for cross reactions. In all cases, a combined parasitological diagnosis using Kato-Katz (24 slides and Saline Gradient (1 g of feces were used as reference. At baseline, diagnosis by POC-CCA (1-2 cassettes showed 6% sensitivity, inaccurately predicting a low prevalence of Schistosoma mansoni infections (2 POC-CCA positives/32 egg positives. After urine lyophilization, the sensitivity was increased significantly (p < 0.05. Prevalence rates changed from 2% to 32% (27 POC-CCA positives/32 egg positives, equivalent to parasitological techniques. Most of the trace readings changed to positive after lyophilization while some negatives turned into traces. Cross reaction analysis confirmed the specificity of POC-CCA.Trace readings cannot be primarily defined as positive or negative cases. It is critical to verify case-by-case by concentrating urine 10 fold by lyophilization for the diagnosis. Following lyophilization, persistent trace readings should be read as negatives. No trained technician is needed and cost is restricted to the cost of a lyophilizer and the electricity to run it.

    Carboxysomes, containing the cell's complement of RuBisCO surrounded by a specialized protein shell, are a central component of the cyanobacterial CO(2)-concentrating mechanism. The ratio of two forms of the β-carboxysomal protein CcmM (M58 and M35) may affect the carboxysomal carbonic anhydrase (CcaA) content. We have over-expressed both M35 and M58 in the β-cyanobacterium Synechococcus PCC7942. Over-expression of M58 resulted in a marked increase in the amount of this protein in carboxysomes at the expense of M35, with a concomitant increase in the observed CcaA content of carboxysomes. Conversely, M35 over-expression diminished M58 content of carboxysomes and led to a decrease in CcaA content. Carboxysomes of air-grown wild-type cells contained slightly elevated CcaA and M58 content and slightly lower M35 content compared to their 2% CO(2)-grown counterparts. Over a range of CcmM expression levels, there was a strong correlation between M58 and CcaA content, indicating a constant carboxysomal M58:CcaA stoichiometry. These results also confirm a role for M58 in the recruitment of CcaA into the carboxysome and suggest a tight regulation of M35 and M58 translation is required to produce carboxysomes with an appropriate CA content. Analysis of carboxysomal protein ratios, resulting from the afore-mentioned over-expression studies, revealed that β-carboxysomal protein stoichiometries are relatively flexible. Determination of absolute protein quantities supports the hypothesis that M35 is distributed throughout the β-carboxysome. A modified β-carboxysome packing model is presented.

    Some pollutants can qualitatively affect aquatic freshwater such as rivers, and heavy metals are one of the most important pollutants in aquatic fresh waters. Heavy metals can be found in the form of components dissolved in these waters or in compounds with suspended particles and surface sediments. It can be said that heavy metals are in equilibrium between water and sediment. In this study, the amount of heavy metals is determined in water and different sizes of sediment. To obtain the relationship between heavy metals in water and size-fractionated sediments, a canonical correlation analysis (CCA) was utilized in rivers of the southwestern Caspian Sea. In this research, a case study was carried out on 18 sampling stations in nine rivers. In the first step, the concentrations of heavy metals (Cu, Zn, Cr, Fe, Mn, Pb, Ni, and Cd) were determined in water and size-fractionated sediment samples. Water sampling sites were classified by hierarchical cluster analysis (HCA) utilizing squared Euclidean distance with Ward's method. In addition, for interpreting the obtained results and the relationships between the concentration of heavy metals in the tested river water and sample sediments, canonical correlation analysis (CCA) was utilized. The rivers were grouped into two classes (those having no pollution and those having low pollution) based on the HCA results obtained for river water samples. CCA results found numerous relationships between rivers in Iran's Guilan province and their size-fractionated sediments samples. The heavy metals of sediments with 0.038 to 0.125 mm size in diameter are slightly correlated with those of water samples.

    Full Text Available The highly toxic Cr(VI is a critical component in the Chromated Copper Arsenate (CCA formulations extensively employed as wood preservatives. Remediation of CCA mixed waste and discarded treated wood products is a significant challenge. We demonstrate that UV/TiO2 photocatalysis effectively reduces Cr(VI to less toxic Cr(III in the presence of arsenate, As(V, and copper, Cu(II. The rapid conversion of Cr(VI to Cr(III during UV/TiO2 photocatalysis occurs over a range of concentrations, solution pH and at different Cr:As:Cu ratios. The reduction follows pseudo-first order kinetics and increases with decreasing solution pH. Saturation of the reaction solution with argon during UV/TiO2 photocatalysis had no significant effect on the Cr(VI reduction demonstrating the reduction of Cr(VI is independent of dissolved oxygen. Reduction of Cu(II and As(V does not occur under the photocatalytic conditions employed herein and the presence of these two in the tertiary mixtures had a minimal effect on Cr(VI reduction. The Cr(VI reduction was however, significantly enhanced by the addition of formic acid, which can act as a hole scavenger and enhance the reduction processes initiated by the conduction band electron. Our results demonstrate UV/TiO2 photocatalysis effectively reduces Cr(VI in mixed waste streams under a variety of conditions.

    Full Text Available Studies have shown that ticks are susceptible to infection by entomopathogenic nematodes. These studies indicate different susceptibilities of ticks to infection by these fungi, depending on the tick species, development phase, entomopathogenic nematodes species and strains and the time the ticks are exposed to them. Usually this period ranges from 24 to 72 hours. The aim of this study was to evaluate the infection times in vitro of engorged Rhipicephalus (Boophilus microplus females by the entomopathogenic nematodes Steinernema glaseri CCA strain, by analysis of the ticks' biological parameters. The results show that a 2-hour exposure time was sufficient for the engorged R. microplus females to be infected by S. glaseri CCA, but that a minimum exposure time of 24 hours was necessary to generate treatment efficacy above 90%.Os carrapatos são susceptíveis à infecção por nematoides entomopatogênicos.

    The Wenchuan Ms 8.0 earthquake is one of the largest inland earthquakes in continental China in the last 30 years. Over twenty thousand aftershocks were detected and aftershocks are still occurring along the Longmenshan thrust fault. Facing challenge of such large earthquakes, it is a new problem for our education, training and human resource management about how to respond quickly and arrange effectively to reduce the earthquake disasters and carry out relative researches. For such an earthquake, the Institute of Geophysics, China Earthquake Administration (IGPCEA) organized a series of investigation immediately after the quake. The researches include application in seismology, geomagnetism, seismotectonics, engineering seismology, earthquake engineering and socio-seismology. In the third day after the earthquake, many young scientists involved in the deployment of mobile seismic stations to record aftershock sequence. Up to now, 79 experts of our institute have been arranged to go to the meizoseismal region for monitoring and investigation. Among them, over 40 young scientists are no more than 40 years old, including many graduates. Less than 36 hours after the Wenchuan earthquake, 17 quick reports have been sent to China Earthquake Administration for the consultation of the emergency response. These researches dealt with a wide-band of topics from earthquake location, focal mechanism, rupture processes to suggestion on the rescue actions. According to experiences and lessons of the field works in the Wenchuan earthquake, it is deserved for us to think how to arrange theoretical courses and practical training more practical for young graduates and scientists to meet the demands of the reduction of earthquake disasters.

    This is a thorough investigation into contemporary young people and their media life. The article conceptualizes a typology of media life, drawing on a theoretical body involving the sociology of generations, life course research, media life and individualization. This empirically derived typology...... makes a strong instrument for an understanding of the media life of the young, furnishing insights into how they have constructed their use of media. The investigation is based on a robust national survey with Swedes born 1994–2001, conducted in 2010, and focusing on four media: television, gaming......, the Internet and mobile devices. Two of the findings are particularly surprising. Firstly, the results reveal that the young generally lead heterogeneous media lives, varying with age and sex. Secondly, although some young people literarily live their life in media, there are also de facto young who live...

    Electroencephalographic (EEG) recordings are often contaminated with muscle artifacts. This disturbing myogenic activity not only strongly affects the visual analysis of EEG, but also most surely impairs the results of EEG signal processing tools such as source localization. This article focuses on the particular context of the contamination epileptic signals (interictal spikes) by muscle artifact, as EEG is a key diagnosis tool for this pathology. In this context, our aim was to compare the ability of two stochastic approaches of blind source separation, namely independent component analysis (ICA) and canonical correlation analysis (CCA), and of two deterministic approaches namely empirical mode decomposition (EMD) and wavelet transform (WT) to remove muscle artifacts from EEG signals. To quantitatively compare the performance of these four algorithms, epileptic spike-like EEG signals were simulated from two different source configurations and artificially contaminated with different levels of real EEG-recorded myogenic activity. The efficiency of CCA, ICA, EMD, and WT to correct the muscular artifact was evaluated both by calculating the normalized mean-squared error between denoised and original signals and by comparing the results of source localization obtained from artifact-free as well as noisy signals, before and after artifact correction. Tests on real data recorded in an epileptic patient are also presented. The results obtained in the context of simulations and real data show that EMD outperformed the three other algorithms for the denoising of data highly contaminated by muscular activity. For less noisy data, and when spikes arose from a single cortical source, the myogenic artifact was best corrected with CCA and ICA. Otherwise when spikes originated from two distinct sources, either EMD or ICA offered the most reliable denoising result for highly noisy data, while WT offered the better denoising result for less noisy data. These results suggest that

    There is a need for diagnostic techniques which are sensitive, specific, rapid and easy to perform at the point-of-care. The aim of this study was to evaluate the diagnostic performance of the Circulating Cathodic Antigen (POC-CCA) assay for Schistosoma mansoni in four schools along the coast of Lake Victoria in Mwanza Region, Tanzania, and to optimize the reading of the POC-CCA test lines by using a computer software image analysis. Initially, a pilot study in 106 school children indicated that time of urine collection did not have an impact on CCA results as 84.9% (90) had identical scores from a urine collected in the morning and a urine taken at midday after drinking 0.5 L of water. The main study was conducted among 404 school children (aged 9-12 years) where stool and urine samples were collected for three consecutive days. For S. mansoni diagnosis, stool samples were examined for eggs with duplicate Kato-Katz smears, whereas urine samples were tested for presence of antigen by POC-CCA. The proportion of positive individuals for S. mansoni by one POC-CCA was higher compared to two Kato-Katz smears (66.1% vs. 28.7%; p < 0.0001). Both proportions increased expectedly when three POC-CCAs were compared to six Kato-Katz smears (75.0% vs. 42.6%; p < 0.0001). Three POC-CCAs were more sensitive (94.7%) than six Kato-Katz smears (53.8%) using the combined results of three POC-CCAs and six Kato-Katz smears as the 'gold standard'. To optimize the reading of the POC-CCA, a Software tool (Image Studio Lite®) was used to read and quantify the colour (expressed as pixels) of the test line on all positive tests, showing a positive correlation between number of pixels and the visually scored intensities and between number of pixels and egg counts. In conclusion, the POC-CCA assay seems to be a more appropriate tool for S. mansoni diagnosis compared to the Kato-Katz method in endemic communities such as Mwanza Region. Optimization of the tool in terms of cassette

    Flow parameters can induce pathological changes in the arteries. We propose a method to asses those parameters using a 3D computer model of the flow in the Common Carotid Artery. Input data was acquired using an automatic 2D ultrasound wall tracking system. This data has been used to generate a 3D geometry of the artery. The diameter and wall thickness have been assessed individually for every patient, but the artery has been taken as a 75mm straight tube. The Young's modulus for the arterial walls was calculated using the pulse pressure, diastolic (minimal) diameter and wall thickness (IMT). Blood flow was derived from the pressure waveform using a 2-parameter Windkessel model. The blood is assumed to be non-Newtonian. The computational models were generated and calculated using commercial code. The coupling method required the use of Arbitrary Lagrangian-Euler formulation to solve Navier-Stokes and Navier-Lame equations in a moving domain. The calculations showed that the distention of the walls in the model is not significantly different from the measurements. Results from the model have been used to locate additional risk factors, such as wall shear stress or circumferential stress, that may predict adverse hypertension complications.

    Full Text Available A utilização do preservante CCA (sais de cromo, cobre e arsênio tem sido questionada devido ao impacto relacionado à dispersão, principalmente, do cobre e do arsênio para o ambiente, antes de sua completa fixação na madeira. Outra questão se relaciona à disposição indevida dos resíduos provenientes da madeira tratada, viabilizando a lixiviação devido à maior área passível desses rejeitos sujeita a tal fenômeno. Este trabalho teve como objetivo a produção de painéis de partículas, avaliando o efeito da adição de resíduos de Pinus sp. tratado com sais de cromo, cobre e arsênio (CCA, em associação com material da mesma espécie sem preservantes, além de alterações no teor de adesivo poliuretano à base de mamona empregado na produção. As propriedades dos painéis produzidos foram determinadas conforme recomendações da NBR 14810-3: 2006. Por meio de análise estatística, observou-se que a adição da madeira tratada proporcionou desempenho superior no inchamento em espessura (2 h, ao passo que esse insumo utilizado na mesma proporção que a madeira sem preservantes foi significante, obtendo os melhores resultados na adesão interna. Os módulos de ruptura e de elasticidade na flexão não sofreram influência das variações nos insumos utilizados nos painéis. Os painéis, em grande parte, apresentaram-se em conformidade com os principais requisitos nesse âmbito, mostrando a possibilidade da utilização dos referidos insumos na produção, além da obtenção de um produto com considerável apelo ambiental.

    2013-04-01

    Ectopic fat deposition in skeletal muscles, liver, heart, and other tissues has been closely linked with the development of lean tissues' insulin resistance and progression toward type 2 diabetes mellitus. Mechanisms of overexposure of these tissues to fatty acids include increased de novo lipogenesis, impaired fatty acid oxidation and increased fatty acid flux to these organs. White adipose tissues are the main organs responsible for the regulation of circulating fatty acids. It has been clearly demonstrated that pre-diabetes individuals and individuals with diabetes display impaired adipose tissue dietary fatty acid storage that may lead to increased circulating flux and exaggerated lean tissue fatty acid exposure. Additionally, brown adipose tissue depots are less metabolically active in individuals with type 2 diabetes. We have developed a series of novel in vivo investigative tools using positron emission tomography to comprehensively assess postprandial interorgan fatty acid partitioning and white and brown adipose tissue metabolism in subjects with pre-diabetes and type 2 diabetes. Our findings shed new lights into the sophisticated mechanisms that regulate fatty acid partitioning and energy homeostasis during the development of type 2 diabetes. New links between abnormal dietary fatty acid metabolism and early myocardial metabolic and functional defects are now being uncovered in humans with the hope to find novel ways to predict and avoid the devastating complications of diabetes.

  4. An investigation of the self-related concepts and foreign language motivation of young Deaf and hard-of-hearing learners in Hungary

    Full Text Available In recent years increased attention has been given in applied linguistics to the learning processes of various groups of special needs (SN students, especially to those whose achievement is impeded by dyslexia or other learning difficulties. However, students with sensory impairment, particularly those who are Deaf or severely hard of hearing (HOH, seem to have remained on the periphery of second language acquisition (SLA research although they constitute a highly interesting group both from a linguistic as well as a cultural point of view. Since the best approach to understanding how this special minority handles foreign language learning is by first exploring their so-called individual differences, a nationwide research project was launched in Hungary to investigate students’ language learning beliefs, motivation, strategy use and motivated learning behavior. As part of that project, the present paper intends to detail how self-related concepts of hearing impaired students at eight different SN schools  an be described. In order to gain an in-depth understanding, a mixed-method research design was employed. First, a barrier-free instrument was used to measure learner variables among 105 14-19-year-old Deaf and HOH learners. Then 31 individual interviews were conducted with selected students using maximum variety sampling. The quantitative data indicate that Deaf and HOH (D/HH learners lack pronounced, well-developed and detailed future ideal L2 selves and corresponding visions to guide their learning. Another important finding is the paramount importance of language learning experience for our D/HH participants. Based on the analysis of the qualitative data, we can conclude that students’ language learning experiences are largely shaped by the choice of language used as the medium of education, the intensity and content of the English classes as well as how far students internalize extrinsic motives.

    Full Text Available A intensa exploração econômica tem causado diminuição do estoque original das espécies madeireiras amazônicas, incluindo aquelas de alta durabilidade natural destinadas a usos em contato com o solo. A escassez dessas madeiras resulta na elevação do preço, inviabilizando economicamente seu uso, sendo uma alternativa a substituição por espécies plantadas de rápido crescimento tratadas com preservativos. Outra vantagem, além da econômica, de utilizar espécies plantadas em substituição às tradicionais é ambiental, pois reduzirá a pressão exploratória sobre aquelas. Este estudo teve por objetivo avaliar o grau de degradação biológica de madeira de eucalipto citriodora (Corymbia citriodora (Hook. K.D. Hill & L.A.S.

    Time-resolved cell culture assays circumvent the need to set arbitrary end-points and reveal the dynamics of quality controlled experiments. However, they lead to the generation of large data sets, which can represent a complexity barrier to their use. We therefore developed the Time-Resolved Cell Culture Assay (TReCCA) Analyser program to perform standard cell assay analyses efficiently and make sophisticated in-depth analyses easily available. The functions of the program include data normalising and averaging, as well as smoothing and slope calculation, pin-pointing exact change time points. A time-resolved IC50/EC50 calculation provides a better understanding of drug toxicity over time and a more accurate drug to drug comparison. Finally the logarithmic sensor recalibration function, for sensors with an exponential calibration curve, homogenises the sensor output and enables the detection of low-scale changes. To illustrate the capabilities of the TReCCA Analyser, we performed on-line monitoring of dissolved oxygen in the culture media of the breast cancer cell line MCF-7 treated with different concentrations of the anti-cancer drug Cisplatin. The TReCCA Analyser is freely available at www.uni-heidelberg.de/fakultaeten/biowissenschaften/ipmb/biologie/woelfl/Research.html. By introducing the program, we hope to encourage more systematic use of time-resolved assays and lead researchers to fully exploit their data.

    This study evaluated the safety, tolerability, and immunogenicity of an investigational quadrivalent meningococcal conjugate vaccine, MenACWY-CRM, when administered concomitantly with a combined tetanus, reduced diphtheria, and acellular pertussis (Tdap) vaccine, in subjects aged 11 to 25 years. Subjects received either MenACWY-CRM and Tdap, MenACWY-CRM and saline placebo, or Tdap and saline placebo. No significant increase in reactogenicity and no clinically significant vaccine-related adverse events (AEs) occurred when MenACWY-CRM and Tdap were administered concomitantly. Similar immunogenic responses to diphtheria, tetanus, and meningococcal (serogroups A, C, W-135, and Y) antigens were observed, regardless of concomitant vaccine administration. Antipertussis antibody responses were comparable between vaccine groups for filamentous hemagglutinin and were slightly lower, although not clinically significantly, for pertussis toxoid and pertactin when the two vaccines were administered concomitantly. These results indicate that the investigational MenACWY-CRM vaccine is well tolerated and immunogenic and that it can be coadministered with Tdap to adolescents and young adults.

  11. An RNA-binding complex involved in ribosome biogenesis contains a protein with homology to tRNA CCA-adding enzyme.

    2013-10-01

    Full Text Available A multitude of proteins and small nucleolar RNAs transiently associate with eukaryotic ribosomal RNAs to direct their modification and processing and the assembly of ribosomal proteins. Utp22 and Rrp7, two interacting proteins with no recognizable domain, are components of the 90S preribosome or the small subunit processome that conducts early processing of 18S rRNA. Here, we determine the cocrystal structure of Utp22 and Rrp7 complex at 1.97 Å resolution and the NMR structure of a C-terminal fragment of Rrp7, which is not visible in the crystal structure. The structure reveals that Utp22 surprisingly resembles a dimeric class I tRNA CCA-adding enzyme yet with degenerate active sites, raising an interesting evolutionary connection between tRNA and rRNA processing machineries. Rrp7 binds extensively to Utp22 using a deviant RNA recognition motif and an extended linker. Functional sites on the two proteins were identified by structure-based mutagenesis in yeast. We show that Rrp7 contains a flexible RNA-binding C-terminal tail that is essential for association with preribosomes. RNA-protein crosslinking shows that Rrp7 binds at the central domain of 18S rRNA and shares a neighborhood with two processing H/ACA snoRNAs snR30 and snR10. Depletion of snR30 prevents the stable assembly of Rrp7 into preribosomes. Our results provide insight into the evolutionary origin and functional context of Utp22 and Rrp7.

    Black-oil, compositional and thermal simulators have been developed to address different physical processes in reservoir simulation. A number of different types of discretization methods have also been proposed to address issues related to representing the complex reservoir geometry. These methods are more significant for fractured reservoirs where the geometry can be particularly challenging. In this project, a general modular framework for reservoir simulation was developed, wherein the physical models were efficiently decoupled from the discretization methods. This made it possible to couple any discretization method with different physical models. Oil characterization methods are becoming increasingly sophisticated, and it is possible to construct geologically constrained models of faulted/fractured reservoirs. Discrete Fracture Network (DFN) simulation provides the option of performing multiphase calculations on spatially explicit, geologically feasible fracture sets. Multiphase DFN simulations of and sensitivity studies on a wide variety of fracture networks created using fracture creation/simulation programs was undertaken in the first part of this project. This involved creating interfaces to seamlessly convert the fracture characterization information into simulator input, grid the complex geometry, perform the simulations, and analyze and visualize results. Benchmarking and comparison with conventional simulators was also a component of this work. After demonstration of the fact that multiphase simulations can be carried out on complex fracture networks, quantitative effects of the heterogeneity of fracture properties were evaluated. Reservoirs are populated with fractures of several different scales and properties. A multiscale fracture modeling study was undertaken and the effects of heterogeneity and storage on water displacement dynamics in fractured basements were investigated. In gravity-dominated systems, more oil could be recovered at a given pore

    Objective:To investigate the clinical characteristics and prognosis of pulpotomy with Pulp-dent Multi-Cal (PMC) in young permanent incisors. Methods: Twenty-five young permanet incisors with vital pulps and complicated crown fractures were treated by pulpotomy with PMC at the Emergency Department of Peking University School and Hospital of Stomatology. The teeth were checked clinically and radiographically during fixed intervals. Healing of the pulp was considered to have taken place if the following criteria were met; absence of clinical symptoms, absence of apical radiolucency, continued root development in immature teeth, radiographic evidence of dentin bridge formation, and positive response to pulp vitality tests. The results were compared with the teeth which underwent pulpotomy with preparation made by our hospital. Results:Followed up for 6 -15 months (median 12 months) , on basis of the criteria for pulp healing, all teeth got successful treatment. And all the teeth showed radiographic evidence of dentin bridge formation within 1 to 3 months after pulpotomy. The operation time of PMC pulpotomy was significantly shortened (P <0.01).

    It is shown that innovation is regarded as a central success factor in tackling challenges of the future. Especially in high-wage regions such as Germany companies find themselves in a fierce innovation competition marked by growing challenges at the global level and the growing dynamism of innovation processes. Young industries are typically faced with much uncertainty in regard to strategy and technology, presenting their individual companies, most of them small and young themselves, with the challenge of having to rely on limited resources to develop innovative products, services and processes and launch them on the market. This provides the backdrop to the present dissertation, which inquires into the factors that determine the success of cooperative innovation projects in young branches of industry. Using the German photovoltaic industry as an example, the study empirically determines major determinants of success of joint innovation projects in young industries and derives recommendations for action for the management of companies and innovation networks.

    Vulvovaginitis is the most common cause of gynecological complaints in young girls. Factors which cause vulvovaginitis include, among other things, low level of sexual hormones (hypoestrogenism), the anatomical proximity of the rectum and delicate vulvar skin and vaginal mucosa. Usually vulvovaginitis in young girls is caused by non-specific factors. The aim of the study was to present the most frequent causes of vulvovaginitis in young girls.

  8. Orientation and the Young Orienteer

    Science.gov (United States)

    Walsh, S. E.; Martland, J. R.

    Orientation within orienteering is dependent on the use of two basic strategies; that is, either a compass or Magnetic-North-based strategy, which relies on the use of one set of information; or the use of a map and landmark-based strategy which relies on the use of at least two sets of information. Walsh and found that, when given the choice, young children use the compass-based strategy when following complex potentially disorientating routes.The efficacy of these two basic orientation strategies was investigated within three different orienteering environments: (1) a familiar known environment; (2) a familiar unknown environment and (3) an unfamiliar unknown environment.Subjects, age range from 9 to 10think aloud particularly the introduction of basic skills to young performers. They support the argument that is essential to introduce the map and compass simultaneously and that relocation and orientation skills should be coached concurrently.

  9. Hypertension in young adults.

    2016-01-01

    Hypertension remains a major societal problem affecting 76 million, or approximately one third, of US adults. While more prevalent in the older population, an increasing incidence in the younger population, including athletes, is being observed. Active individuals, like the young and athletes, are viewed as free of diseases such as hypertension. However, the increased prevalence of traditional risk factors in the young, including obesity, diabetes mellitus, and renal disease, increase the risk of developing hypertension in younger adults. Psychosocial factors may also be contributing factors to the increasing incidence of hypertension in the younger population. Increased left ventricular wall thickness and mass are increasingly found in young adults on routine echocardiograms and predict future cardiovascular events. This increasing incidence of hypertension in the young calls for early surveillance and prompt treatment to prevent future cardiac events. In this review we present the current epidemiological data, potential mechanisms, clinical implications, and treatment of hypertension in young patients and athletes.

    Full Text Available In this research, we focus on young people and their daily lives, bringing elements discussing leisure, family, education and work. Research conducted with a group of young skaters in a public track skating in the city of Porto Alegre - RS. In a total nine months of direct observation, each reported in Field Diaries. We seek to understand how the leisure of young people who gave the practice of skateboarding, was related to other aspects of their daily lives. After completing the work, we consider that - to remain in practice the skateboard - young people needed to reconcile the charges of their families, in addition to labels and stereotypes imposed from "outside" the universe of practitioners of this sport. We noticed also that young people go through all this in order to keep their "projects" on the skateboard.

  1. Diagnosing young onset dementia can be challenging.

    Ahmed, Samrah; Baker, Ian; Butler, Christopher R

    2016-05-01

    Although the risk of developing dementia increases with age, onset can be as early as the third or fourth decade of life. Genetic influences play a more important role in younger than in older people with dementia, so young onset dementia may cluster in families. Diagnosing young onset dementia is challenging. The range of possible presenting features is broad, encompassing behavioural, cognitive, psychiatric and neurological domains, and symptoms are often subtle initially. Frequently the complaints are misattributed to stress or depression, and the patient is falsely reassured that they are too young to have dementia. The most common causes of young onset dementia are early onset forms of adult neurodegenerative conditions and alcohol. Vascular dementia is the second most common cause of young onset dementia after Alzheimer's disease. Conventional vascular risk factors may be absent and diagnosis relies on imaging evidence of cerebrovascular disease. Obtaining a detailed history remains the most important part of the workup and usually requires corroboration by a third party. Undertaking a basic neurological examination is also important. Those with suspected young onset dementia should be referred to a neurology-led cognitive disorders clinic where available as the differenti diagnosis is considerably broader tha in older adults and requires specialist investigation.

  20. Ages of young stars

    Soderblom, David R; Jeffries, Rob D; Mamajek, Eric E; Naylor, Tim

    2013-01-01

    Determining the sequence of events in the formation of stars and planetary systems and their time-scales is essential for understanding those processes, yet establishing ages is fundamentally difficult because we lack direct indicators. In this review we discuss the age challenge for young stars, specifically those less than ~100 Myr old. Most age determination methods that we discuss are primarily applicable to groups of stars but can be used to estimate the age of individual objects. A reliable age scale is established above 20 Myr from measurement of the Lithium Depletion Boundary (LDB) in young clusters, and consistency is shown between these ages and those from the upper main sequence and the main sequence turn-off -- if modest core convection and rotation is included in the models of higher-mass stars. Other available methods for age estimation include the kinematics of young groups, placing stars in Hertzsprung-Russell diagrams, pulsations and seismology, surface gravity measurement, rotation and activ...

  1. The Angry Young Men

    Directory of Open Access Journals (Sweden)

    Odeta Manuela Belei

    2010-09-01

    Full Text Available The “angry young men” were a group of mostly working and middle class British playwrights and novelists who became prominent in the 1950s. The group’s leading members included John Osborne and Kingsley Amis. The phrase was originally coined by the Royal Court Theatre’s press officer to promote John Osborne’s Look Back in Anger. It is thought to be derived from the autobiography of Leslie Paul, founder of the Woodcraft Folk, whose Angry Young Men was published in 1951. Following the success of the Osborne play, the label was later applied by British newspapers to describe young British writers who were characterized by disillusionment with traditional English society. The term was always imprecise, began to have less meaning over the years as the writers to whom it was originally applied became more divergent, and many of them dismissed the label as useless.

  9. Continuity and Discontinuity of Depression from Late Adolescence to Young Adulthood: The Mediating and Moderating Effects of Young Adults’ Socioeconomic Attainment

    Wickrama, K. A. S.; Conger, Rand D.; Lorenz, Federick O.; Martin, Monica

    2011-01-01

    Using prospective, longitudinal data from 467 youth over a 13-year period (late adolescence and young adulthood), the present study investigates three research questions: (1) to what extent do elevations in depressed mood continue (homotypic continuity) from adolescence to young adulthood, (2) to what extent do young adults’ socioeconomic attainments and failures sustain the depressed mood from adolescence to young adulthood and (3) to what extent do young adults’ socioeconomic attainments or failures mediate the continuity and discontinuity of depressive symptoms across this period? The results from our structural equation modeling (SEM) analyses suggest that continuity of depressive symptoms from late adolescence to young adulthood is mediated in part by economic and work achievements or failures of young adults after controlling for adolescent conduct disorder/antisocial behavior, parents’ psychopathology and family adversity. Additionally, the results indicate that the continuity of depressed mood across the early life course is conditioned (stabilized or disrupted) by young adult socioeconomic achievements or failures.

  14. SUPPLEMENT USE BY YOUNG ATHLETES

    2007-09-01

    Full Text Available This paper reviews studies of supplement use among child and adolescent athletes, focusing on prevalence and type of supplement use, as well as gender comparisons. Supplement use among adult athletes has been well documented however there are a limited number of studies investigating supplement use by child and adolescent athletes. A trend in the current literature revealed that the most frequently used supplements are in the form of vitamin and minerals. While health and illness prevention are the main reasons for taking supplements, enhanced athletic performance was also reported as a strong motivating factor. Generally, females are found to use supplements more frequently and are associated with reasons of health, recovery, and replacing an inadequate diet. Males are more likely to report taking supplements for enhanced performance. Both genders equally rated increased energy as another reason for engaging in supplement use. Many dietary supplements are highly accessible to young athletes and they are particularly vulnerable to pressures from the media and the prospect of playing sport at increasingly elite levels. Future research should provide more direct evidence regarding any physiological side effects of taking supplements, as well as the exact vitamin and mineral requirements for child and adolescent athletes. Increased education for young athletes regarding supplement use, parents and coaches should to be targeted to help the athletes make the appropriate choices

    2016-01-01

    In this paper, we describe a compact and practical algorithm to construct Hermitian Young projection operators for irreducible representations of the special unitary group SU(N), and discuss why ordinary Young projection operators are unsuitable for physics applications. The proof of this construction algorithm uses the iterative method described by Keppeler and Sj\\"odahl. We further show that Hermitian Young projection operators share desirable properties with Young tableaux, namely a nested hierarchy when "adding a particle". We end by exhibiting the enormous advantage of the Hermitian Young projection operators constructed in this paper over those given by Keppeler and Sj\\"odahl.

    2009-01-01

    Full Text Available An increasing number of patients under 40 years of age are being hospitalized with the diagnosis of acute myocardial infarction. This is partly due to the increased prevalance of risk factors for atherosclerosis in the younger age group; especially increased incidence of impaired fasting glucose, high triglyceride, low high-density lipoprotein levels and increased waist to hip ratio. However, non-atherosclerotic coronary artery disease or hypercoagulability should also be investigated or at least suspected in the younger patients. The pathophysiology of different clinical conditions and disease states which cause acute coronary syndromes in the young patients are reviewed, and the diagnostic modalities and therapatic options for these conditions are briefly discussed by searching for "premature atherosclerosis", "hypercoagulable states", "risk factors for atherosclerosis in youth", "novel risk factors for atherosclerosis", "non-atherosclerotic coronary artery diseases" in PubMed.

    We present a spectroscopic and kinematic analysis of 79 nearby M dwarfs in 77 systems. All are low-proper-motion southern hemisphere objects and were identified in a nearby star survey with a demonstrated sensitivity to young stars. Using low-resolution optical spectroscopy from the Red Side Spectrograph (RSS) on the South African Large Telescope (SALT), we have determined radial velocities, H-alpha, Lithium 6708\\AA, and Potassium 7699\\AA~equivalent widths linked to age and activity, and spectral types for all our targets. Combined with astrometric information from literature sources, we identify 44 young stars. Eighteen are previously known members of moving groups within 100 parsecs of the Sun. Twelve are new members, including one member of the TW Hydra moving group, one member of the 32 Orionis moving group, nine members of Tucana-Horologium, one member of Argus, and two new members of AB Doradus. We also find fourteen young star systems that are not members of any known groups. The remaining 33 star syst...

    Full Text Available Penalty, including imprisonment comprises one of the basic forms of reaction to crime. It differs from other possible penalties in the degree of discomfort and in the legal consequences. There are also different goals in case of criminal penalty as a legal and social consequence of a crime or misconduct. Imprisonment aims at taking different actions which consequently, should lead to the situation where the criminal does not return to committing crimes. It is so called penitentiary rehabilitation which is a multidimensional phenomenon and it should be considered from the modern society point of view. Its range includes correction of inadequate individual’s behavior and his or her adaptation of norms and values shared by the general public, as well as taking and being persistent in the process of designing oneself, own personality and consistent implementation of the self- vision in the future, organized hierarchically for the given time periods. Therefore, different means and action are taken under the implementation of imprisonment. Moreover, convicted prisoners are divided into different groups in penitentiaries. One of the groups is the group of young convicts. The goal of this article is to examine and describe the opinion of the young convicts on the penitentiary as a penal and rehabilitation institution. To perform the study, sixty young convicts were selected. In the test method, the diagnostic survey was applied. The original authoring questionnaire was used in the study. The study was performed in the Penitentiary in Radom, in December 2012.

    The process of hydration and solidification of young concrete has significant effect on the long term strength and durability of concrete. The electrical property of concrete provides a direct and practical method for monitoring and investigating the hydration process of young concrete. This study developed an advanced system for measurement of electrical parameters, used to study the electrical properties of young concrete. The test results provided the electric parameters for concretes with different water binder ratios and different mineral admixture incorporations. The variations and characteristics of the measured electrical parameters were closely related to the physical and chemical properties of young concrete. These parameters were used to analyze and study the hydration process of young concrete.

  7. Activation of antioxidant defenses in whole saliva by psychosocial stress is more manifested in young women than in young men.

    Directory of Open Access Journals (Sweden)

    Viktoriia Tsuber

    Full Text Available Psychosocial stress has been long known to have deleterious effects on health. Nevertheless, an exposure to moderate stressors enhances resilience and promotes health benefits. Male and female organisms differ in many aspects of health and disease. The aim of this study was to investigate antioxidant activity and oxidative damage in saliva in a psychosocial stress paradigm in men and women. Here, we show that an acute stressor of moderate strength augments antioxidant activity and decreases oxidative damage in whole saliva of young people. An examination stress caused a significant increase of catalase activity, accompanied by a decrease of levels of oxidized proteins. Levels of thiobarbituric acid-reacting substances did not increase at stress, indicating that lipid peroxidation was not activated. The stress-induced alterations were more manifested in young women compared to young men. Thus, antioxidant protective mechanisms are more activated by a moderate stressor in young women than in young men.

    Dorval, Julien; Boily, Christian

    2017-03-01

    Stellar clusters form with a high level of substructure, inherited from the molecular cloud and the star formation process. Evidence from observations and simulations also indicate the stars in such young clusters form a subvirial system. The subsequent dynamical evolution can cause important mass loss, ejecting a large part of the birth population in the field. It can also imprint the stellar population and still be inferred from observations of evolved clusters. Nbody simulations allow a better understanding of these early twists and turns, given realistic initial conditions. Nowadays, substructured, clumpy young clusters are usually obtained through pseudo-fractal growth and velocity inheritance. We introduce a new way to create clumpy initial conditions through a ''Hubble expansion'' which naturally produces self consistent clumps, velocity-wise. In depth analysis of the resulting clumps shows consistency with hydrodynamical simulations of young star clusters. We use these initial conditions to investigate the dynamical evolution of young subvirial clusters. We find the collapse to be soft, with hierarchical merging leading to a high level of mass segregation. The subsequent evolution is less pronounced than the equilibrium achieved from a cold collapse formation scenario.

    2009-12-01

    Participation of adolescents and young women in strenuous sports activity may lead to various metabolic and psychological derangements of clinical relevance to the endocrinologist. The most common manifestations encountered in practice are primary and secondary amenorrhea, reduced bone mineral density and eating disorders. The occurrence of all three together has been named "the athletic triad". The underlying hormonal drivers that lead to some of these manifestations are the reduced leptin level as well as the persistent low grade stress response commonly observed in such females. "Exercise-related female reproductive dysfunction" (ERFRD), can possibly include short-term (infertility) and long-term (osteoporosis) consequences. Functional hypothalamic amenorrhea, a manifestation of ERFRD in adolescence, is an integrated response to the combination of excessive physical and emotional stress, exercise, and/or reduced food intake characterized by decreased endogenous GNRH secretion. The primary aim of treating these athletes should be the prevention of the development of any component of the triad as well as the whole complex by educating athletes, trainers, parents and health care professionals about proper nutrition and safe training. The long term prognosis is good. However, significant long term morbidity may affect these young women later in life.

    We predicted sex of 140 Snowy Owl (Bubo scandiacus) nestlings out of 34 nests at our Barrow, Alaska, study area to develop a technique for sexing these owls in the field. We primarily sexed young, flightless owls (3844 d old) by quantifying plumage markings on the remiges and tail, predicting sex, and collecting blood samples to test our field predictions using molecular sexing techniques. We categorized and quantified three different plumage markings: two types of bars (defined as markings that touch the rachis) and spots (defined as markings that do not touch the rachis). We predicted sex in the field assuming that males had more spots than bars and females more bars than spots on the remiges and rectrices. Molecular data indicated that we correctly sexed 100% of the nestlings. We modeled the data using random forests and classification trees. Both models indicated that the number and type of markings on the secondary feathers were the most important in classifying nestling sex. The statistical models verified our initial qualitative prediction that males have more spots than bars and females more bars than spots on flight feathers P6P10 for both wings and tail feathers T1 and T2. This study provides researchers with an easily replicable and highly accurate method for sexing young Snowy Owls in the field, which should aid further studies of sex-ratios and sex-related variation in behavior and growth of this circumpolar owl species. ?? 2011 The Raptor Research Foundation, Inc.

    Devitalization and demineralization processing of biodegradable polymer and extracellular matrix (ECM) hybrid constructs was explored for the effect on the retention of ECM components and construct osteogenicity. Hybrid constructs were generated by seeding osteogenically predifferentiated rat mesenchymal stem cells (MSCs) onto electrospun poly(ε-caprolactone) fiber meshes and culturing in osteogenic medium for 12 or 16 days within a flow perfusion bioreactor to create an ECM coating. The resulting constructs were then either devitalized (using a freeze-thaw or a detergent technique), devitalized and demineralized, or left untreated, and subsequently characterized for DNA, glycosaminoglycan, collagen, and calcium content. The osteogenicity of each construct was investigated by culturing MSCs on the hybrid constructs within a flow perfusion bioreactor for 4, 8, and 12 days in osteogenic medium. Histological staining demonstrated that devitalization via the freeze-thaw method retained the thickest coating of ECM components within the constructs. Demineralization and devitalization processing of ECM coated constructs resulted in a decrease in their osteogenicity.

    Alódia Brasil

    Full Text Available Alcohol consumption among young adults is widely accepted in modern society and may be the starting point for abusive use of alcohol at later stages of life. Chronic alcohol exposure can lead to visual function impairment. In the present study, we investigated the spatial luminance contrast sensitivity, colour arrangement ability, and colour discrimination thresholds on young adults that weekly consume alcoholic beverages without clinical concerns. Twenty-four young adults were evaluated by an ophthalmologist and performed three psychophysical tests to evaluate their vision functions. We estimated the spatial luminance contrast sensitivity function at 11 spatial frequencies ranging from 0.1 to 30 cycles/degree. No difference in contrast sensitivity was observed comparing alcohol consumers and control subjects. For the evaluation of colour vision, we used the Farnsworth-Munsell 100 hue test (FM 100 test to test subject's ability to perform a colour arrangement task and the Mollon-Reffin test (MR test to measure subject's colour discrimination thresholds. Alcohol consumers made more mistakes than controls in the FM100 test, and their mistakes were diffusely distributed in the FM colour space without any colour axis preference. Alcohol consumers also performed worse than controls in the MR test and had higher colour discrimination thresholds compared to controls around three different reference points of a perceptually homogeneous colour space, the CIE 1976 chromaticity diagram. There was no colour axis preference in the threshold elevation observed among alcoholic subjects. Young adult weekly alcohol consumers showed subclinical colour vision losses with preservation of spatial luminance contrast sensitivity. Adolescence and young adult age are periods of important neurological development and alcohol exposure during this period of life might be responsible for deficits in visual functions, especially colour vision that is very sensitive to

    已有跨种族、跨文化婚姻研究忽视了中国男性和西方女性这种稀少但重要的类别。涉外通婚是一个蕴含深刻社会意义并折射出多方面结构性社会问题、价值取向、民族因素的复杂社会现象,应该从理论的深度、战略的高度去思考这一现象及其对国家和民族带来的影响。通过调查在爱尔兰的西方女性眼中的中国男性形象,探索性地测量了中国男性对于西方女性的婚恋吸引力,从西方女性的视角将中国男性的形象与西方男性的形象予以比较,分析西方女性的择偶偏好,发现中国男性真正“不那么受欢迎”的原因,从而在文化建构、性别气质和媒体塑造等方面进一步分析中国男性在西方世界里形象呈现的深层缘由。%Previous studies almost have ignored the issue of intercultural/interracial marriages between Chinese men and Western women. Although the number of this type of marriages might still be scarce, it is sociologically interesting and important. Intercultural/Interracial marriage is a complex social phenomenon which implies profound social significance, structural social problems, ethnic issues and value orientation. By investigating the images of Chinese men in the eyes of Western women living in Ireland, and incorporating statistical description as well as Neural Network Model, this paper surveys the Chinese men's marital attraction to Western women. Based on the data collected, it contrasts the images of Western men and Chinese men in Western women's perception. The mate preference of Western women is analyzed, and the reasons for Chinese men's “unpopularity” in mate selection are disclosed. The Chinese masculinity and the underlying cause for its formation is discussed from the perspectives of Chinese and Western cultures, such as cultural construction, gender traits, media, and so on.

    Science.gov (United States)

    Rice, Emily

    , the results of our work will improve our understanding of objects at the intersection of stars and planets and be directly applicable to understanding the atmospheres of directly-imaged exoplanets. The assembled investigators are the absolute best team to accomplish this work. They have extensive and diverse observational experience in astrometry, photometry, and spectroscopy from the optical through the mid-IR, spanning nearly the entire spectral energy distribution of young brown dwarfs and encompassing their most fundamental observational properties. They have considerable experience mining large photometric catalogs and identifying low-gravity very low mass objects. The team maintains collaborations with two groups actively modelling brown dwarf and exoplanet atmospheres and interior evolution. The proposed research organically combines several ongoing projects into a cohesive program that will efficiently incorporate WISE data to disentangle the ambiguous and interdependent physical properties of young brown dwarfs. As a result of the team's previous observational projects, we have assembled a dataset that positions us to best interpret WISE observations brown dwarfs and identify new young brown dwarfs in the WISE archive. A significant parallax program is ongoing, and all of the computing resources and many of the analysis tools are already in place, including several well-tested pipelines for data reduction and analysis and model comparisons. The team will incorporate undergraduate students in the project through an existing NSF-funded REU program.

    Recently Donkin defined signed Young modules as a simultaneous generalization of Young and twisted Young modules for the symmetric group. We show that in odd characteristic, if a Specht module $S^\\lambda$ is irreducible, then $S^\\lambda$ is a signed Young module. Thus the set of irreducible Specht modules coincides with the set of irreducible signed Young modules. This provides evidence for our conjecture that the signed Young modules are precisely the class of indecomposable self-dual module...

    Children come into contact very early with the written language. The work of Emilia Ferreiro, a student of Piaget, has shown that from early on, well before they can read, they know that the written word has a meaning. Their successive hypotheses show an elaboration which does not occur by chance. Experience shows that babies have a specific interest for a book as an object. They recognize the value of the pictures, as much representations of their mental representations as are words, whereas these two capacities evolve in a complementary fashion. The capacity to be interested by a narrative introduces a new form of organization in the chain of representations, whether they refer to absent or imaginary objects. A good story has a special place among the narratives the child hears, which actually have the specific structures of the written language. The authors of this work report a number of examples of very young children who are put in contact with books. They see in this a new model for mental health work which can be set up by virtue of meetings outside the school rooms, the mental health services, and even of the libraries, by people of different professional skills, in order to loosen the vice of the children's daily routine, and to give the child time to dream with the books, and to draw the adults in to a salutary disorder.

    Full Text Available The aim of this study was to examine the relationship between motivational characteristics and dispositional flow. In order to accomplish this goal, motivational profiles emerging from key constructs within Achievement Goal Theory and Self-Determination Theory were related to the dispositional flow measures. A sample of 413 young athletes (Age range 12 to 16 years completed the PMCSQ-2, POSQ, SMS and DFS measures. Cluster analysis results revealed three profiles: a "self-determined profile" characterised by higher scores on the task-involving climate perception and on the task orientation; a "non-self-determined profile", characterised by higher scores on ego-involving climate perception and ego orientation; and a "low self-determined and low non-self-determined profile" which had the lowest dispositional flow. No meaningful differences were found between the "self-determined profile" and the "non-self-determined profile" in dispositional flow. The "self-determined profile" was more commonly associated with females, athletes practising individual sports and those training more than three days a week. The "non-self-determined profile" was more customary of males and athletes practising team sports as well as those training just two or three days a week

    Full Text Available Background: Weight loss does not necessarily decrease the negative appraisal of a formerly overweight individual. Since past weight history tends to be disclosed in several contexts, this study aims to investigate whether negative appraisals are gender-specific and if they are modulated by the evaluators' own BMI. Methods: 202 young adults (106 male and 96 female viewed a picture of a young attractive female (target accompanied by one of two statements about her past weight (overweight (OW or always kept a normal weight (NW, and then rated her using the Fat Phobia Scale (FPS. Results: Female evaluators rated the target with the OW statement more negatively than the target with the NW statement. In contrast, males exposed to the OW statement rated the target as having fewer emotional/psychological problems and being less stupid/uncreative. BMI only influenced ratings in males, where those with higher BMI ascribed more negative attributes to the target with the NW statement than the OW statement. Conclusion: Information on weight history impacts upon the appraisal of peers. These effects are dependent on gender and BMI. Knowing that a young female was overweight triggered negative evaluations from females but did not appear to impact the judgment of males.

    Full Text Available Inflamm-aging indicates the chronic inflammatory state resulting from increased secretion of proinflammatory cytokines and mediators such as IL-6 in the elderly. Our principle objective was to identify cell types that were affected with aging concerning IL-6 secretion in the murine model. We compared IL-6 production in spleen cells from both young and aged mice and isolated several types of cells from spleen and investigated IL-6 mRNA expression and protein production. IL-6 protein productions in cultured stromal cells from aged mice spleen were significantly high compared to young mice upon LPS stimulation. IL-6 mRNA expression level of freshly isolated stromal cells from aged mice was high compared to young mice. Furthermore, stromal cells of aged mice highly expressed IL-6 mRNA after LPS injection in vivo. These results suggest that stromal cells play a role in producing IL-6 in aged mice and imply that they contribute to the chronic inflammatory condition in the elderly.

    The latest results in the research of forming planetary systems have led several authors to compile a sample of candidates for searching for planets in the vicinity of the sun. Young stellar associations are indeed excellent laboratories for this study, but some of them are not close enough to allow the detection of planets through adaptive optics techniques. However, the existence of very close young moving groups can solve this problem. Here we have compiled the members of the nearest young moving groups, as well as a list of new candidates from our catalogue of late-type stars possible members of young stellar kinematic groups, studying their membership through spectroscopic and photometric criteria.

    2011-04-01

    Full Text Available The purpose of this paper is to investigate whether there exist differences in website visualization according to the gender of the respondents as young consumers. For the main purpose, a questionnaire was designed from the literature review, and data were collected from 252 undergraduate students. Analyses of chi-square and t-tests were conducted for hypotheses testing. The results show that six website visualization characteristics are different by young consumers’ gender. These gender-based differences include different color preferences, not using a derogatory statement about rivals, using rounded lines and shapes, 4-6 colors in typeface, female figures in photos and expert language in the websites. The findings of this study reveal how e-marketing executives can harmonize the visualization of websites based on the gender of the targeted young consumers. The main value of this paper is the empirical analysis of the website visualization from a gender perspective. The study explicates to what extent website visualization is important in online purchasing decisions of the young consumers by gender and provides useful information for e-marketing executives. Better understanding of young consumers’ perspectives of website visualization by gender is critical for designing and managing effective websites that can help businesses attract and retain online young customers.

    2009-02-01

    Using optimized voxel-based morphometry (VBM), this study systematically investigated the differences and similarities of brain structural changes during the early three developmental periods of human lives: childhood, adolescence and young adulthood. These brain changes were discussed in relationship to the corresponding cognitive function development during these three periods. Magnetic Resonance Imaging (MRI) data from 158 Chinese healthy children, adolescents and young adults, aged 7.26 to 22.80 years old, were included in this study. Using the customized brain template together with the gray matter/white matter/cerebrospinal fluid prior probability maps, we found that there were more age-related positive changes in the frontal lobe, less in hippocampus and amygdala during childhood, but more in bilateral hippocampus and amygdala and left fusiform gyrus during adolescence and young adulthood. There were more age-related negative changes near to central sulcus during childhood, but these changes extended to the frontal and parietal lobes, mainly in the parietal lobe, during adolescence and young adulthood, and more in the prefrontal lobe during young adulthood. So gray matter volume in the parietal lobe significantly decreased from childhood and continued to decrease till young adulthood. These findings may aid in understanding the age-related differences in cognitive function.

    Full Text Available Social workers, working with young people ought to be aware of the values, needs and problems of contemporary young people. Therefore, it is necessary to develop study programmes of Social Work that would reflect the current situation of modern youth and be oriented towards effective techniques for working with young people. The most common methods described in the literature are counseling, supervision, case management, self-reflection. The article highlights the method of social intervention, which objectively and fully assesses the problem situation and establishes the connections and relationships between the young man and his relatives, friends or authorities. This method helps to enable young people to solve their own problems. The aim of the research is to analyze the application features of the social intervention model when working with young people. The objectives are to discuss the activities of youth organizations in the field of social 99SOCIALINIO TINKLO INTERVENCIJOS MODELIO TAIKYMAS DIRBANT SU JAUNIMU work; to highlight the methods of social workers‘ practice; to investigate the application of social intervention model, enabling young people to solve their own problems. The methods applied include comparative analysis of scientific literature, monitoring, social intervention model. The survey revealed that when social workers enable young people to solve their own problems, a model of social intervention allows to evaluate not only the relationships of close people or family members, but also highlights the roles of youth organizations or social workers and their positive effect on the customer‘s actions. Thus, when applying the method of social intervention, social workers play an important role, as well as their professional knowledge and skills to establish the connection with the client are extremely important in order to promote the client‘s reflection.

  3. CCA三支决策模型的边界域样本处理%Dealing with Samples in Boundary Regions of Three-Way Decisions Model Based on CCA

    构造性覆盖算法(constructive covering algorithm,CCA)三支决策模型在学习过程中根据样本分布特征,自动产生正域、负域和边界域。该模型为边界域样本处理问题提供了新的思路。重点讨论了基于CCA的三支决策的边界域样本处理问题。对边界域样本处理提出了两种决策方案:一种为处理全部的边界域样本,给出了距中心最近原则、距边界最近原则、万有引力原则3种方法;另一种为处理部分的边界域样本,即只对满足一定条件的边界域样本作进一步的划分,这样使不满足条件的边界域样本仍保留在边界域,提高了边界域样本处理的正确率。用十字交叉法在5组数据集上对这两种决策方案进行了对比,实验结果表明,处理部分边界域样本时正确率更高,效果更好。%The three-way decisions model based on constructive covering algorithm (CCA) produces automatically three regions:positive regions (POS), negative regions (NEG) and boundary regions (BND) according to the distri-bution characteristic of samples. The model provides a new idea to deal with samples in BND for the theory of three-way decisions. This paper proposes two methods to deal with samples in BND:The first method deals with all samples in BND, which gives three principles, nearest to the center principle, nearest to the boundary principle and gravity principle;The second one deals with part of samples in BND, i.e., the samples which satisfy some condi-tions are dealt with, and the rest samples are still in the BND. The second method promotes the accuracy. This paper compares the two methods on five datasets using 10-fold cross-validation. The experimental results show that the effect and accuracy of dealing with part of samples in BND are better than those of dealing with all samples in BND.

    This study prospectively investigates associations between youth moderate-to-vigorous-intensity physical activity (MVPA) and body composition in young adult women using data from the Dietary Intervention Study in Children (DISC) and the DISC06 Follow-Up Study. MVPA was assessed by questionnaire on 5 occasions between the ages 8 and 18 years and at age 25-29 years in 215 DISC female participants. Using whole body dual-energy x-ray absorptiometry (DXA), overall adiposity and body fat distribution were assessed at age 25-29 years by percent body fat (%fat) and android-to-gynoid (A:G) fat ratio, respectively. Linear mixed effects models and generalized linear latent and mixed models were used to assess associations of youth MVPA with both outcomes. Young adult MVPA, adjusted for other young adult characteristics, was significantly inversely associated with young adult %fat (%fat decreased from 37.4% in the lowest MVPA quartile to 32.8% in the highest (p-trend = 0.02)). Adjusted for youth and young adult characteristics including young adult MVPA, youth MVPA also was significantly inversely associated with young adult %fat (β=-0.40 per 10 MET-hrs/wk, p = .02) . No significant associations between MVPA and A:G fat ratio were observed. Results suggest that youth and young adult MVPA are important independent predictors of adiposity in young women.

    Objectives Although sex and relationship education (SRE) represents a key strand in policies to safeguard young people and improve their sexual health, it currently lacks statutory status, government guidance is outdated and a third of UK schools has poor-quality SRE. We aimed to investigate whether current provision meets young people's needs. Design Synthesis of qualitative studies of young people's views of their school-based SRE. Setting Eligible studies originated from the UK, Ireland, the USA, Australia, New Zealand, Canada, Japan, Iran, Brazil and Sweden. Participants Studies of students aged 4–19 in full-time education, young adults ≤19 (not necessarily in full-time education) or adults ≤25 if recalling their experiences of school-based SRE. Results –69 publications were identified, with 55 remaining after quality appraisal (representing 48 studies). The synthesis found that although sex is a potent and potentially embarrassing topic, schools appear reluctant to acknowledge this and attempt to teach SRE in the same way as other subjects. Young people report feeling vulnerable in SRE, with young men anxious to conceal sexual ignorance and young women risking sexual harassment if they participate. Schools appear to have difficulty accepting that some young people are sexually active, leading to SRE that is out of touch with many young people's lives. Young people report that SRE can be negative, gendered and heterosexist. They expressed dislike of their own teachers delivering SRE due to blurred boundaries, lack of anonymity, embarrassment and poor training. Conclusions SRE should be ‘sex-positive’ and delivered by experts who maintain clear boundaries with students. Schools should acknowledge that sex is a special subject with unique challenges, as well as the fact and range of young people's sexual activity, otherwise young people will continue to disengage from SRE and opportunities for safeguarding and improving their sexual health will be

    We present the Young Exoplanet Transit Initiative (YETI), in which we use several 0.2 to 2.6m telescopes around the world to monitor continuously young (< 100 Myr), nearby (< 1 kpc) stellar clusters mainly to detect young transiting planets (and to study other variability phenomena on time-scales from minutes to years). The telescope network enables us to observe the targets continuously for several days in order not to miss any transit. The runs are typically one to two weeks long, about three runs per year per cluster in two or three subsequent years for about ten clusters. There are thousands of stars detectable in each field with several hundred known cluster members, e.g. in the first cluster observed, Tr-37, a typical cluster for the YETI survey, there are at least 469 known young stars detected in YETI data down to R=16.5 mag with sufficient precision of 50 milli-mag rms (5 mmag rms down to R=14.5 mag) to detect transits, so that we can expect at least about one young transiting object in this cl...

    Objective: To investigate the effect of behavior training on the learning and memory of young rats with fetal growth restriction (FGR). Methods: The model of FGR was established by passive smoking method to pregnant rats.The new-born rats were divided into FGR group and normal group, and then randomly subdivided into trained and untrained group respectively. Morris water maze behavior training was performed on postnatal months 2 and 4, then learning and memory abilities of young rats were measured by dark-avoidance testing and step-down testing. Results: In the dark-avoidance and step-down testing, the young rats' performance of FGR group was worse than that of control group, and the trained group was better than the untrained group significantly. Conclusion: FGR young rats have descended learning and memory abilities. Behavior training could improve the young rats' learning and memory abilities, especially for the FGR young rats.

  20. Attitudes to Exercise and Diabetes in Young People with Type 1 Diabetes Mellitus: A Qualitative Analysis.

    Kirsty Ryninks

    Full Text Available To investigate young people's attitudes to, and understanding of, physical activity on glycaemic control in Type 1 Diabetes Mellitus.Four focus groups with 11-14 and 15-16 year olds were conducted with twelve young people with Type 1 Diabetes, from within a larger study investigating physical activity and fitness. Qualitative analysis of the focus group data was performed using Interpretative Phenomenological Analysis.Four superordinate themes were identified: Benefits of Exercise, Knowledge and Understanding, Information and Training and "You can do anything". Young people felt that exercising helped them to manage their diabetes and had a beneficial psychological and physical impact on their bodies. They reported a lack of knowledge and understanding about diabetes among school staff and other young people. The overwhelming sense from young people was that although diabetes impacts upon their lives, with preparation, physical activity can take place as normal.Whilst young people had an awareness of the physical and psychological benefits of exercise in managing their diabetes, they experienced difficulties at school. Professional support and discussions with young people, giving tailored strategies for managing Type 1 Diabetes during exercise are needed. Healthcare teams should ensure that the support and educational needs of school staff are met. Providing more opportunities to empower young people to take on the responsibility for their Type 1 Diabetes care is merited. Young people felt diabetes did not stop them from participating in activities; it is simply a part of them that needs managing throughout life.

  19. Collisions in young triple systems

    CERN Document Server

    Rawiraswattana, Krisada; Goodwin, Simon P

    2011-01-01

    We perform N-body simulations of young triple systems consisting of two low-mass companions orbiting around a significantly more massive primary. We find that, when the orbits of the companions are coplanar and not too widely separated, the chance of a collision between the two companions can be as high as 20 per cent. Collisions between one of the companions (always the less massive) and the primary can also occur in systems with unequal-mass companions. The chance of collisions is a few per cent in systems with more realistic initial conditions, such as with slightly non-coplanar orbits and unequal-mass companions. If the companions start widely separated then collision are very rare except in some cases when the total mass of the companions is large. We suggest that collisions between members of young multiple systems may explain some unusual young multiple systems such as apparently non-coeval companions.

    2012-06-01

    Full Text Available Stroke affects mainly people aged over 65 years, and atherosclerosis predominates as the main etiopathogenic factor in ischemic stroke (IS. On the other hand, cardiac embolism and arterial dissection are the most frequent causes of IS in patients aged less than 45 years. However, inappropriate control of traditional vascular risk factors in young people may be causing a significant increase of atherosclerosis-related IS in this population. Furthermore, a variety of etiologies, many of them uncommon, must be investigated. In endemic regions, neurocysticercosis and Chagas' disease deserve consideration. Undetermined cause has been still reported in as many as one third of young stroke patients.

    2016-01-01

    The survival gap between adolescents and young adults (AYAs) with hematological malignancies persists in many countries. To determine to what extent it does in Japan, we investigated survival and treatment regimens in 211 Japanese AYAs (15-29 years) in the Osaka Cancer Registry diagnosed during 2001-2005 with hematological malignancies, and compared adolescents (15-19 years) with young adults (20-29 years). AYAs with acute lymphoblastic leukemia (ALL) had a poor 5-year survival (44%), particularly young adults (29% vs. 64% in adolescents, p = 0.01). Additional investigation for patients with ALL revealed that only 19% of young adults were treated with pediatric treatment regimens compared with 45% of adolescents (p = 0.05). Our data indicate that we need to focus on young adults with ALL and to consider establishing appropriate cancer care system and guidelines for them in Japan.

  5. The limit shape problem for ensembles of Young diagrams

    CERN Document Server

    Hora, Akihito

    2016-01-01

    This book treats ensembles of Young diagrams originating from group-theoretical contexts and investigates what statistical properties are observed there in a large-scale limit. The focus is mainly on analyzing the interesting phenomenon that specific curves appear in the appropriate scaling limit for the profiles of Young diagrams. This problem is regarded as an important origin of recent vital studies on harmonic analysis of huge symmetry structures. As mathematics, an asymptotic theory of representations is developed of the symmetric groups of degree n as n goes to infinity. The framework of rigorous limit theorems (especially the law of large numbers) in probability theory is employed as well as combinatorial analysis of group characters of symmetric groups and applications of Voiculescu's free probability. The central destination here is a clear description of the asymptotic behavior of rescaled profiles of Young diagrams in the Plancherel ensemble from both static and dynamic points of view.

    2016-12-01

    Objectives Male sex, young age, and frequent gambling are considered as risk factors for gambling disorder (GD) and stress might be one of the triggers of gambling behavior among problem gamblers. Conversely, well-developed coping with stress might counteract gambling problems. The Proactive Coping Theory provides a promising approach for the further development of preventive and treatment measures. The objective of the study was to investigate different facets of proactive coping (PC) in young male gamblers. Methods Young men from Bavaria were recruited via the Munich citizens' registry (n = 2,588) and Facebook invitations (n = 105). In total, 173 out of 398 individuals were positively screened for frequent gambling and/or signs of related problems and completed the baseline questionnaire of the Munich Leisure-time Study. Factors investigated include gambling problems, PC, impulsiveness, social support, and psychological distress. Results Gambling problems were associated with lower levels of preventive coping as well as of adaptive reaction delay. The associations were also significant when controlled for impulsiveness and general psychological distress. Preventive coping moderated the association between social support and gambling problems. Discussion and conclusions Young men with gambling problems less frequently prevent the occurrence of stressors and more often react hasty when these occur. While the investigated group reported good social support, this factor was negatively associated with GD only among individuals with good preventive coping. Preventive coping poses a useful construct for selective prevention and treatment as it can be modified in professional interventions.

    2014-01-01

    Full Text Available The purpose of this study was to evaluate the benefits of replacing Ordinary Portland Cement (OPC with Corncob Ash (CCA blended cements. The cement industry contributes considerable amount of Carbon Dioxide (CO2 emissions into the atmosphere. The main contribution of CO2 emissions from cement production results from the process of creating Calcium Oxide (CaO from limestone (CaCO3 commonly known as the calcination process. Blending OPC with a pozzolanic material will assist in the reduction of CO2 emissions due to calcination as well as enhance the quality of OPC. There are various pozzolanic materials such as fly ash, rice husk, silica fume and CCA that could be promising partial replacement for OPC. In this study, CCA will serve as the primary blending agent with OPC. An experiment was performed to designate an appropriate percentage replacement of CCA that would comply with specific standards of cement production. The experimental plan was designed to analyze compressive strength, workability and thermal performance of various CCA blended cements. The data from the experiment indicates that up to 10% CCA replacement could be used in cement production without compromising the structural integrity of OPC. In addition, it was found that the compressive strength and workability of the resulting concrete could be improved when CCA is added to the mixtures. Furthermore, it was shown that the introduction of 10% CCA can lead to significant reduction in thermal conductivity of the mixture.

    It is unclear whom animals select to huddle with for thermoregulation. In this study, we investigated whom Japanese macaque (Macaca fuscata) mothers huddled with-their young offspring or other adult group members-when there is need for thermoregulation. We used a focal-animal sampling method, targeting 17 females at Katsuyama, Okayama Prefecture, Japan. A majority of huddling among adult females was recorded during winter season (December, January, and February). Females who had young (0- or 1-year-old) offspring huddled less frequently with other adult females compared to females who did not have young offspring in winter. However, including young offspring, the frequency of huddling with any other individuals did not differ by whether females had young offspring. Moreover, the females who did not have young offspring huddled with other adult females more often in cloudy than in sunny weather during winter season. In contrast, females who had young offspring increased huddling with their young offspring in cloudy than in sunny weather, but did not do so with other adult females. This study indicates that Japanese macaque mothers huddle with their young offspring instead of other adult females when there is need for thermoregulation.

  10. Fertility preservation in young patients with cancer

    Full Text Available Infertility can arise as a consequence of treatment of oncological conditions. The parallel and continued improvement in both the management of oncology and fertility cases in recent times has brought to the forefront the potential for fertility preservation in patients being treated for cancer. Many survivors will maintain their reproductive potential after the successful completion of treatment for cancer. However total body irradiation, radiation to the gonads, and certain high dose chemotherapy regimens can place women at risk for acute ovarian failure or premature menopause and men at risk for temporary or permanent azoospermia. Providing information about risk of infertility and possible interventions to maintain reproductive potential are critical for the adolescent and young adult population at the time of diagnosis. There are established means of preserving fertility before cancer treatment; specifically, sperm cryopreservation for men and in vitro fertilization and embryo cryopreservation for women. Several innovative techniques are being actively investigated, including oocyte and ovarian follicle cryopreservation, ovarian tissue transplantation, and in vitro follicle maturation, which may expand the number of fertility preservation choices for young cancer patients. Fertility preservation may also require some modification of cancer therapy; thus, patients' wishes regarding future fertility and available fertility preservation alternatives should be discussed before initiation of therapy.

    Full Text Available Abstract Backround Appearance concerns are of increasing importance in young men's lives. We investigated whether muscle dissatisfaction is associated with psychological symptoms, dietary supplement or anabolic steroid use, or physical activity in young men. Methods As a part of a questionnaire assessment of health-related behaviors in the population-based FinnTwin16 study, we assessed factors associated with muscle dissatisfaction in 1245 men aged 22–27 using logistic regression models. Results Of men, 30% experienced high muscle dissatisfaction, while 12% used supplements/steroids. Of highly muscle-dissatisfied men, 21.5% used supplements/steroids. Mean body mass index, waist circumference, or leisure aerobic activity index did not differ between individuals with high/low muscle dissatisfaction. Muscle dissatisfaction was significantly associated with a psychological and psychosomatic problems, alcohol and drug use, lower height satisfaction, sedentary lifestyle, poor subjective physical fitness, and lower life satisfaction. Conclusion Muscle dissatisfaction and supplement/steroid use are relatively common, and are associated with psychological distress and markers of sedentary lifestyle.

  2. New morbidity of the young

    Stanković Biljana

    2002-01-01

    Full Text Available In the present phase of epidemiological transition, the most frequent causes of youth morbidity are disorders in reproductive health, mental disorders and injuries which are not life threatening. This, so-called new youth morbidity, is most often caused by their risky behavior, which in the field of sexuality often leads to unplanned pregnancies and abortions, as well as sexually transmitted infections. Misuse of tobacco, alcohol and narcotics, which is most commonly started in adolescence, has an unfavorable short-term and long-term influence on the psycho-physical health of the young. All research, in the world and in our country, indicate gradual yet constant growth of sexual activity of the youth and the age decrease of its starting point, especially when girls are in question. Due to insufficient maturity and inadequate knowledge and consciousness on the necessity of protecting reproductive health, sexual behavior of young people can often be characterized as insufficiently responsible and not supplemented with the usage of adequate protective measures. The result is frequently abortion, which terminates 90% of unplanned and unwanted pregnancies in this age. This creates health and psychosocial risks, as well as giving birth in adolescence which is contrary to the modern health concepts that giving birth should not be performed too early, while the young are still developing. A significant increase in the frequency of sexually transmitted diseases is also present, to which the youth are especially susceptible due to the specific development period in which they are in. A serious medical and sociopathological problem of contemporary society represents the greater and greater misuse of psychoactive substances among the young people, with a tendency of decreasing the average age they are consumed for the first time, as well as the use of drugs and alcohol. With the increase of the anti-smoking campaign and restrictive measures in highly

    Full Text Available Lebanon is a small democratic country with a population of less than four million and a range of diversity; there are at least 18 different religious sects and 19 different political parties. The diversity among ethnic, religious and/or political groups has created conflicts that severely impact the Lebanese economy, environment, politics and most importance our young citizens. The aim of this investigation is to capture students’ awareness and attitudes toward the accountability and mechanisms of peace and democracy. Data for the study was obtained from extensive literature reviews and questionnaire surveys of 70 high school students. The investigation was conducted in the fall of the year 2013. The results of the study showed that most Lebanese young citizen view peace and democracy process associated with the end of violence and conflict behaviors; very small percent of respondents believe that bringing peace and democracy process should be answered by the people or by themselves. Results also indicate a lack of a sense of security among young citizen. This raises the urgent need to put into practice an effective peace education program that inspires and motivates young citizens to be involved in the peace and the democracy building process.

  4. Interactions between exoplanets and the winds of young stars

    2014-01-01

    Full Text Available The topology of the magnetic field of young stars is important not only for the investigation of magnetospheric accretion, but also responsible in shaping the large-scale structure of stellar winds, which are crucial for regulating the rotation evolution of stars. Because winds of young stars are believed to have enhanced mass-loss rates compared to those of cool, main-sequence stars, the interaction of winds with newborn exoplanets might affect the early evolution of planetary systems. This interaction can also give rise to observational signatures which could be used as a way to detect young planets, while simultaneously probing for the presence of their still elusive magnetic fields. Here, we investigate the interaction between winds of young stars and hypothetical planets. For that, we model the stellar winds by means of 3D numerical magnetohydrodynamic simulations. Although these models adopt simplified topologies of the stellar magnetic field (dipolar fields that are misaligned with the rotation axis of the star, we show that asymmetric field topologies can lead to an enhancement of the stellar wind power, resulting not only in an enhancement of angular momentum losses, but also intensifying and rotationally modulating the wind interactions with exoplanets.

    2012-01-01

    For more than four decades, scientists have been trying to find an answer to one of the most fundamental questions in paleoclimatology, the `faint young Sun problem'. For the early Earth, models of stellar evolution predict a solar energy input to the climate system which is about 25% lower than today. This would result in a completely frozen world over the first two billion years in the history of our planet, if all other parameters controlling Earth's climate had been the same. Yet there is ample evidence for the presence of liquid surface water and even life in the Archean (3.8 to 2.5 billion years before present), so some effect (or effects) must have been compensating for the faint young Sun. A wide range of possible solutions have been suggested and explored during the last four decades, with most studies focusing on higher concentrations of atmospheric greenhouse gases like carbon dioxide, methane or ammonia. All of these solutions present considerable difficulties, however, so the faint young Sun prob...

    2016-03-01

    Despite the rapid growth of the gambling industry over the last 40 years, there have been few large-scale, nationally representative longitudinal studies of gambling among young adults. We use data from the National Longitudinal Study of Adolescent to Adult Health to investigate whether and how the gambling behavior of young adults is associated with their religious beliefs and practices during adolescence. We find that young adults who grew up as conservative Protestants, mainline Protestants, Mormons, and Jehovah's Witnesses; those were raised in a community with a higher percentage of conservative Protestants; and those who attended religious services weekly are less likely to have ever gambled. Among gamblers, young adults who attended religious services up to three times per month as adolescents are more likely to experience gambling problems than those who never attend. Notably, accounting for a young adult's propensity for risk-taking behavior does not explain the associations between religion and gambling.

    Ebner, Natalie C; Johnson, Marcia K

    2009-06-01

    Studies have found that older compared with young adults are less able to identify facial expressions and have worse memory for negative than for positive faces, but those studies have used only young faces. Studies finding that both age groups are more accurate at recognizing faces of their own than other ages have used mostly neutral faces. Thus, age differences in processing faces may not extend to older faces, and preferential memory for own age faces may not extend to emotional faces. To investigate these possibilities, young and older participants viewed young and older faces presented either with happy, angry, or neutral expressions; participants identified the expressions displayed and then completed a surprise face recognition task. Older compared with young participants were less able to identify expressions of angry young and older faces and (based on participants' categorizations) remembered angry faces less well than happy faces. There was no evidence of an own age bias in memory, but self-reported frequency of contact with young and older adults and awareness of own emotions played a role in expression identification of and memory for young and older faces.

    2012-01-01

    Full Text Available Serious cardiac complications occurring during noncardiac surgery in a young and otherwise normal person can be quite alarming for the anesthesiologist. We report here the case of a young, healthy woman who immediately after an uncomplicated spinal surgery developed a clinical picture suggestive of an acute myocardial infarction (MI with positive relevant investigations. However, she had an abrupt and full clinical recovery and complete normalization of her cardiac investigations within a few days of this event and thereafter continued to lead a normal, symptom-free life unlike the usual course in an MI; her coronary angiography was also normal. A diagnosis of perioperative stress-induced cardiomyopathy or Takotsubo cardiomyopathy was subsequently made. This condition is characterized by a rapid, severe, but reversible, cardiac dysfunction triggered by physical or mental stress. Awareness of this entity should help anesthesiologists manage better this infrequent, but potentially life-threatening, perioperative complication.

    Full Text Available In the present study, we investigated discrepancies between two components of stereotyping by means of the popular notion that women are better at multitasking behaviors: the cognitive structure in individuals (personal belief and the perceived consensus regarding certain beliefs (perceived belief of groups. With focus on this notion, we examined whether there was empirical evidence for the stereotype’s existence and whether and how it was shared among different age groups. Data were collected from 241 young (n = 129 and older (n = 112 German individuals. The reported perceptions of gender effects at multitasking were substantial and thus demonstrated the existence of its stereotype. Importantly, in young and older adults, this stereotype existed in the perception of attributed characteristics by members of a collective (perceived belief of groups. When contrasting this perceived belief of groups and the personal belief, older adults showed a similar level of conformation of the gender stereotype while young adults were able to differentiate between these perspectives. Thus, young adults showed a discrepancy between the stereotype’s components cognitive structure in individuals and perceived consensus regarding certain beliefs.

    This paper investigates the incidence of dyslexia among young offenders in Kuwait. A total of 91 children/young adults from 8 juvenile delinquent welfare centres across Kuwait were interviewed and tested. A measure of non-verbal reasoning ability was used to exclude those with low general ability. The remaining 53 participants were tested on their ability to identify alliteration and rhyme, retain and manipulate sequences of digit and letter names, decode novel letter strings and identify words within letter chains. Participants' reading accuracy, rate of reading, reading comprehension and ability to spell correctly dictated text were also assessed. These measures were used to determine those with indicators of dyslexia. The results indicated that the percentage of individuals presenting evidence of dyslexia was much larger (greater than 20%) in this population of young offenders than would be expected based on the national average (around 6%) of dyslexics in Kuwait derived from a nationwide study (A survey study of dyslexia in Kuwait, Kuwait Dyslexia Association: Kuwait City; 2002). These findings replicate previous evidence for an increased frequency of dyslexia among young offenders. The implications of such findings are discussed in terms of dyslexia awareness, socio-cultural factors, education and intervention, particularly in Kuwait juvenile delinquent welfare centres.

    Context: NGC 205 is a peculiar dwarf elliptical galaxy hosting in its center a population of young blue stars. Their origin is still matter of debate, the central fresh star formation activity possibly being related to dynamical interactions between NGC 205 and M 31. Aims: The star formation history in the central 30´´ (~120 pc) around the NGC 205 central nucleus is investigated in order to obtain clues to the origin of the young stellar population. Methods: Deep HST/ACS CCD photometry is compared with theoretical isochrones and luminosity functions to characterize the stellar content of the region under study and compute the recent SF rate. Results: Our photometry reveals a previously undetected blue plume of young stars clearly distinguishable down to I≃ 26. Our analysis suggests that 1.9 × 105 M_⊙ were produced between approximately 62 Myr and 335 Myr ago in the NGC 205 inner regions, with a latest minor episode occurring ~25 Myr ago. This implies a star formation rate of ~7× 10-4 M_⊙/yr over this period. Conclusions: The excellent fit of the observed luminosity function of young main sequence stars obtained with a model having a constant star formation rate argues against a tidally triggered star formation activity over the last ~300 Myr. Rather, a constant SF may be consistent with NGC 205 being on its first interaction with M 31.

  2. SELF-ASSESSMENT AMONG YOUNG LEARNERS OF ENGLISH

    Full Text Available The implementation of self-assessment among young learners becomes a challenging issue to include in English classroom assessment. The common belief that children cannot self-assess accurately as adults do seems to yield that the inclusion of self-assessment in TEYL is still not prevalent yet. Self-assessment is an assessment involving the ability in assessing one’s own performance in learning. This is strongly related to one’s metacognition development. The tendency of earlier research investigating metacognitive capacities of young children concludes that mecognition in children is a late developing skill (Lai, 2011. In fact, more recent empirical studies conclude that young children have capability of simple metacognition thought (Lai, 2011. Hence, the inclusion of self-assessment in TEYL can be implemented as an assessment supporting other assessment conducted in classroom. Self-assessment is beneficial in improving students’s own awareness of their learning progress. In Indonesian context, English as a foreign language, has been taught in elementary school since 1994 and generally formative and summative assessments as classroom assessments are employed to assess student’s progress in learning. Self-assessment is an assessment that needs to be considered to include in classroom assessment. This paper discusses self-assessment among young learners, in this context elementary school students studying English.

    The prevalence of thrombophilia and dyslipidemia among young survivors of acute coronary syndrome has not been clearly defined. The purpose of the current study was to investigate the prevalence of multiple markers of thrombophilia and dyslipidemia in a cohort of consecutive young survivors of acute coronary syndrome. The study cohort included 156 consecutive young patients (men women acute coronary syndrome. Analysis included baseline, clinical and epidemiological characteristics, angiographic coronary anatomy, echocardiographic evaluation, extensive lipid and thrombophilia laboratory profiles, and in-hospital and 1-year clinical outcomes for all patients. Acute myocardial infarction was diagnosed in 142 (92 %) patients, of whom 108 (72 %) had ST-segment elevation. Eighteen (12 %) patients had no traditional risk factors. Low levels of high-density lipoprotein (30 mg/dL). Eighteen (12 %) patients were diagnosed with antiphospholipid antibody syndrome (APS), and 73 (47 %) had at least one laboratory finding consistent with thrombophilia. Patients with APS had significantly higher levels of Lp(a) (46 ± 32 vs. 29 ± 31 mg/dL, p = 0.005). APS is a common prothrombotic state found in young survivors of acute coronary syndrome. Lp(a) levels are elevated among APS patients who present with premature acute coronary syndrome.

    Full Text Available The purpose of this article is to discuss the role of Rock in Rio: The Musical, as herald of megafestival Rock in Rio. Driven by the success that musicals have reached in Brazil, we believe that the design of this spectacle of music, dance and staging renews the brand of the rock festival, once it adds the force of young and healthy bodies to its concept. Moreover, the musical provides Rock in Rio with some distance from the controversal trilogy of sex, drugs and rock and roll, a strong mark of past festivals around the world. Thus, the musical expands the possibilities of growth for the brand.

    Dental caries is caused by a combination of infection and diet. This disease, if left untreated, may lead to pain, and impair the quality of life, nutritional status and development of young children. The objective was to investigate the association between snacking and caries in a population at high risk of dental caries. American preschool children (n = 1,206) were recruited in the offices of paediatricians. Data on sociodemographic characteristics, oral hygiene, breast-feeding, use of bottle and snacking were collected by questionnaire. Plaque presence, the number of teeth and their caries status (deft) were scored. The children sampled were 61% Black, 27% White and 10% Asian. Of the 1- to 2-, 2- to 3- and 3- to 4-year-old children, 93.8, 82.4 and 77.3% were caries free, and their mean caries scores were 0.16, 0.58 and 0.93, respectively. Multivariate partial least squares (PLS) modelling revealed plaque presence, lowest income, descriptors for tooth exposure time (number of teeth and age) and cariogenic challenge (total intake of sugar-containing snacks and chips/crisps, and chips intake with a sugar-containing drink) to be associated with more caries. These differences were also found in univariate analyses; in addition, children who continued breast-feeding after falling asleep had significantly higher deft values than those who did not. PLS modelling revealed that eating chips clustered with eating many sweet snacks, candies, popcorn and ice cream. We conclude that, in addition to the traditional risk indicators for caries - presence of plaque, sugar intake and socioeconomic status -, consumption of chips was associated with caries in young children.

    Galactic archaeology is the study of the history of star formation and chemical evolution in the Milky Way, based on present-day stellar populations. Studies of young stars are a key anchor point for Galactic archaeology, since quantities like the initial mass function and the star formation rate can be studied directly in young clusters and star forming regions. Conversely, massive spectroscopic Galactic archaeology surveys can be used as a data source for young star studies.

  1. ROMANIAN YOUNG ENTREPRENEURS FEATURES: AN EMPIRICAL SURVEY

    Directory of Open Access Journals (Sweden)

    Ceptureanu Sebastian Ion

    2015-07-01

    Full Text Available There are many studies linking entrepreneurship and economic development. For specialists and public decision makers, developing entrepreneurship seems to be an easy policy action, even though actions and results are rather debatable. Unfortunately the relevant literature is not so generous concerning youth entrepreneurship. Youth is one of the most vulnerable groups in society, especially in the current economic and demographic situation in European Union and worldwide. At the same time, youth is the period when most people engage in their first job, are gaining financial independence and are assuming new responsibilities and roles shaping their identity. With respect to this, starting their own business is a natural choice for many young people. When considering entrepreneurial potential of young Romanians, there is almost not any data available. This paper aims to disseminate the results of a survey focused on young entrepreneurs, designed to fill the gap in the literature about Romanian young entrepreneurs’ features. The empirical study was divided in five parts: A. Personality of young entrepreneurs, highlighting the main features of behaviour and personality of young entrepreneurs. B. Professional background, focusing on young entrepreneurs’ background and how it influences their interest and performance improvement. C. Risk and crisis acceptance, highlighting the ability of young entrepreneurs to deal with critical situations. D. Business and business environment, focusing on internal and environmental aspects of the business. E. Social - cultural attitude, highlighting the attitude of society (incentives and disincentives to entrepreneurial initiatives of young people. This are excerpts of results from the first part, regarding personality of Romanian young entrepreneurs, concerning issues like level of independence, capacity for innovation, self-confidence, decision making process, level of persistence flexibility of young

    Breast cancer in young women is a significant issue-7% of all female breast cancer is diagnosed in women under 40 years of age. Young women with breast cancer (YWBC) face significant and unique challenges, including a higher likelihood of biologically aggressive disease and metastatic disease at diagnosis, leading to poorer prognosis, more aggressive treatment and long-term treatment-related toxicities, and unique psychosocial concerns. This article summarizes the Young Survival Coalition (YSC) Research Think Tank Meeting, held in Arlington, Virginia, in February 2013, and presents the process that led to YSC's priorities for YWBC research. The meeting's participants focused on six broad categories of investigation in which additional advancements in research on YWBC are crucial: risk factors; treatment; fertility; pregnancy-associated breast cancer; quality of life and survivorship; and metastasis. Several key themes emerged from this meeting. Researchers and advocates felt that a large-scale data registry focused on YWBC is necessary to collect quality information to guide future research for YWBC. This database should include clinical data, genomic profiling of primary tumor and metastatic sites, and an increased focus on fertility and pregnancy following breast cancer treatment. The participants also felt that more must be done to elucidate how and why YWBC develop more aggressive tumors, and to what degree treatment should be modified for young women. The discussions summarized here led to the formulation of YSC's Research Agenda, published in May 2014.

    2007-12-01

    Use of the internet to provide health information to young people is a relatively recent development. Few studies have explored young people's views on how they use internet health websites. This study investigated the navigation, design and content preferences of young people using the Children First for Health (CFfH) website. Young people from five secondary schools completed an internet site navigation exercise, website evaluation questionnaire and participated in informal discussions. Of the participants, 45 percent visited the website section aimed at older adolescents within their first two clicks, regardless of their age. There were conflicting preferences for design and strong preference for gender-specific information on topics such as appearance, relationships, fitness and sexual health. The findings indicate the importance of gaining young people's views to ensure that health information websites meet the needs of their intended audience. Cooperation from schools can facilitate the process of gaining young people's views on internet website navigation, design and content.

    2015-01-01

    We investigate the intrinsic stellar populations (estimated total numbers of OB and pre-main-sequence stars down to 0.1 Mo) that are present in 17 massive star-forming regions (MSFRs) surveyed by the MYStIX project. The study is based on the catalog of >31,000 MYStIX Probable Complex Members with both disk-bearing and disk-free populations, compensating for extinction, nebulosity, and crowding effects. Correction for observational sensitivities is made using the X-ray Luminosity Function (XLF) and the near-infrared Initial Mass Function (IMF)--a correction that is often not made by infrared surveys of young stars. The resulting maps of the projected structure of the young stellar populations, in units of intrinsic stellar surface density, allow direct comparison between different regions. Several regions have multiple dense clumps, similar in size and density to the Orion Nebula Cluster. The highest projected density of ~34,000 stars/pc^2 is found in the core of the RCW38 cluster.

    2013-05-01

    Full Text Available Norwegian authorities’ policy aims at securing an information society for all, emphasizing the importance of accessible and usable Information and Communication Technology (ICT for everyone. While the body of research on young people’s use of ICT is quite comprehensive, research addressing digital differentiation in young people with disabilities’ use of ICT is still in its early days. This article investigates how young people with disabilities’ use, or non-use, of assistive ICT creates digital differentiations. The investigation elaborates on how the anticipations and stereotypes of disability establish an authoritative definition of assistive ICT, and the consequence this creates for the use of the Web by young people with disabilities. The object of the article is to provide enhanced insight into the field of technology and disability by illuminating how assistive ICT sometimes eliminates and sometimes reproduces stereotypes and digital differentiations. The investigation draws on a qualitative interview study with 23 young Norwegians with disabilities, aged 15–20 years. I draw on a theoretical perspective to analyze the findings of the study, which employs the concept of identity multiplicity. The article’s closing discussion expands on technology’s significance in young people’s negotiations of impairment and of perceptions of disability

  15. Strokes in young adults: epidemiology and prevention

    Full Text Available Dževdet Smajlović Department of Neurology, University Clinical Centre Tuzla, School of Medicine, University of Tuzla, Bosnia and Herzegovina Abstract: Strokes in young adults are reported as being uncommon, comprising 10%–15% of all stroke patients. However, compared with stroke in older adults, stroke in the young has a disproportionately large economic impact by leaving victims disabled before their most productive years. Recent publications report an increased incidence of stroke in young adults. This is important given the fact that younger stroke patients have a clearly increased risk of death compared with the general population. The prevalence of standard modifiable vascular risk factors in young stroke patients is different from that in older patients. Modifiable risk factors for stroke, such as dyslipidemia, smoking, and hypertension, are highly prevalent in the young stroke population, with no significant difference in geographic, climatic, nutritional, lifestyle, or genetic diversity. The list of potential stroke etiologies among young adults is extensive. Strokes of undetermined and of other determined etiology are the most common types among young patients according to TOAST (Trial of Org 10172 in Acute Stroke Treatment criteria. Prevention is the primary treatment strategy aimed at reducing morbidity and mortality related to stroke. Therefore, primary prevention is very important with regard to stroke in young adults, and aggressive treatment of risk factors for stroke, such as hypertension, smoking, and dyslipidemia, is essential. The best form of secondary stroke prevention is directed toward stroke etiology as well as treatment of additional risk factors. However, there is a lack of specific recommendations and guidelines for stroke management in young adults. In conclusion, strokes in young adults are a major public health problem and further research, with standardized methodology, is needed in order to give us more

To investigate the psychological outcome and the agreement between self-ratings and proxy-ratings in young individuals after severe traumatic brain injury (TBI). Methods. Twenty pairs of former patients who sustained a severe TBI in their adolescence or early adulthood...... and their significant others (SOs) were contacted around 66 months after injury to complete a measure of psychological and behavioral problems. The Adult Self-Report 18-59 and the Adult Behavior Checklist 18-59 were used. Results. Results showed significant differences compared to the normative sample in the domains...... such as anxiety and depression, withdrawal, thought and attention problems, and personal strength. Conclusion. The findings show that young patients experience psychological dysfunction. Our study suggests that the use of either a self-rating or a proxy-rating would be appropriate for evaluating overt domains...
