Whereas there was significant relationship with education of subjects and pre- test attitude score. Conclusion- structured education programme was highly effective to improve the knowledge score and to improve the attitude score of subjects/ caregiver towards colostomy care of patient.
A Bound on Kappa-Error Diagrams for Analysis of Classifier Ensembles

Kappa-error diagrams are used to gain insights about why an ensemble method is better than another on a given data set. A point on the diagram corresponds to a pair of classifiers. The x-axis is the pairwise diversity (kappa), and the y-axis is the averaged individual error. In this study, kappa is calculated from the 2 × 2 correct/wrong contingency matrix. We derive a lower bound on kappa which determines the feasible part of the kappa-error diagram. Simulations and experiments with real data show that there is unoccupied feasible space on the diagram corresponding to (hypothetical) better ensembles, and that individual accuracy is the leading factor in improving the ensemble accuracy.
Contribution of spike timing to the information transmitted by HVC neurons

In many species, neurons with highly selective stimulus‐response properties characterize higher order sensory areas and/or sensory motor areas of the CNS. In the songbird nuclei, the responses of HVC (used as a proper name) neurons during playback of the bird's own song (BOS) are probably one of the most striking examples of selectivity for natural stimuli. We examined here to what extent spike‐timing carries information about natural and time‐reversed versions of the BOS. From a heterogenous population of 107 HVC neurons recorded in long‐day or short‐day conditions, a standard indicator of stimulus preference based on spike‐count (the d′ index) indicates that a limited proportion of cells can be classified as selective for the BOS (20% with a |d′| > 1). In contrast, quantifying the information conveyed by spike trains with the metric‐space of J.D. Victor & K.P Purpura [(1996) J. Neurophysiol. , 76, 1310–1326] indicates that 62% of the cells display significant amounts of transmitted information, among which 77% are ‘temporal cells’. ‘Temporal cells’ correspond to cells transmitting significant amounts of information when spike‐timing is considered, whereas no information, or lower amounts of transmitted information, is obtained when only spike‐count is considered. Computing a correlation index between spike trains [S. Schreiber et al. (2003) Neurocomputing, 52–54,925–931] revealed that spike‐timing reliability is higher for the forward than for the reverse BOS, whatever the day length and the cell type are. Cells classified as selective in terms of spike‐counts (d′ index) had greater amounts of transmitted information, but cells classified as non‐selective (d′ < 0.5) can also transmit significant amounts of information. Thus, information theory methods demonstrate that a much larger proportion of neurons than expected based on spike‐count only participate in the discrimination between stimuli.
Factors Affecting Acceptance of Mobile Library Applications: Structural Equation Model

Abstract Acceptance and intention to use mobile applications in a library context is attracting a great deal of interest in education field. A sparse amount of research was conducted in mobile library applications (MLA) previously, investigating the influential factors of intention to use MLA. Research here aims to provide empirical support on acceptance of MLA, library access through mobile applications, with the model developed by taking a technology acceptance model (TAM) in MLA context by adding perceived mobility value, system accessibility and satisfaction for investigating the influence on behavioural intention to use MLA. A self-administrated cross-sectional survey was conducted to collect data from 321 users of MLA in the COMSATS Institute of Information Technology (CIIT) in Islamabad, while a structural equation model (SEM) using analysis of moment structure (AMOS) software was used for examining quantitative data. Results revealed that satisfaction and perceived ease of use are direct significant predictors of intention to use MLA, whereas system accessibility was influenced by the perceived ease of use. However, the perceived mobility value shows a weak effect on intention to use MLA in terms of perceived usefulness. Results serve as a guide for effective decision-making in development and resource allocation to ensure the success of the library’s vision and mission.
Designing touch screen user interfaces for future flight deck operations

Many interactional issues with Flight Management Systems (FMS) in modern flight decks have been reported. Avionics designers are seeking for ways to reduce cognitive load of pilots with the aim to reduce the potential for human error. Academic research showed that touch screen interfaces reduce cognitive effort and provide an intuitive way of interaction. A new way of interaction to manipulate radio frequencies of avionics systems is presented in this paper. A usability experiment simulating departures and approaches to airports was used to evaluate the interface and compare it with the current system (FMS). In addition, interviews with pilots were conducted to find out their personal impressions and to reveal problem areas of the interface. Analyses of task completion time and error rates showed that the touch interface is significantly faster and less prone to user input errors than the conventional input method (via physical or virtual keypad). Potential problem areas were identified and an improved interface is suggested.
Molecular characterization of NDP52, a novel protein of the nuclear domain 10, which is redistributed upon virus infection and interferon treatment

The nuclear domain (ND)10 also described as POD or Kr bodies is involved in the development of acute promyelocytic leukemia and virus- host interactions. Immunofluorescence analysis using a variety of human autoimmune sera and monoclonal antibodies showed a typical dot like nuclear staining for ND10, suggesting that this structure consists of several proteins. Two of the ND10 proteins, Sp100 and PML are genetically characterized and show homology with several transcription factors. Here we describe NDP52, an additional novel protein of the ND10. We raised a new mAb C8A2, that specifically recognizes NDP52. Immunofluorescence analysis using this mAb showed a typical nuclear dot staining as it was described for ND10. Isolation and sequencing of the corresponding cDNA revealed that NDP52 has a predicted molecular mass of 52 kD. The deduced amino acid sequence exhibits an extended central coiled coil domain containing a leucine zipper motif. The COOH terminus of NDP52 shows homology with LIM domains, that have recently been described to mediate protein interactions, which let NDP52 appear as a suitable candidate for mediating interactions between ND10 proteins. In vivo, NDP52 is transcribed in all human tissues analyzed. Furthermore, we show that NDP52 colocalizes with the ND10 protein PML and can be redistributed upon viral infection and interferon treatment. These data suggest that ND10 proteins play an important role in the viral life cycle.
Impression management: A literature review and two-component model.

Impression management, the process by which people control the impressions others form of them, plays an important role in interpersonal behavior. This article presents a 2-component model within which the literature regarding impression management is reviewed. This model conceptualizes impression management as being composed of 2 discrete processes. The 1st involves impression motivation ― the degree to which people are motivated to control how others see them. The 2nd component involves impression construction. The 2-component model provides coherence to the literature in the area, address controversial issues, and supplies a framework for future research regarding impression management
Comparison of 10 Perfusion MRI Parameters in 97 Sub-6-Hour Stroke Patients Using Voxel-Based Receiver Operating Characteristics Analysis

Background and Purpose— Perfusion-weighted imaging can predict infarct growth in acute stroke and potentially be used to select patients with tissue at risk for reperfusion therapies. However, the lack of consensus and evidence on how to best create PWI maps that reflect tissue at risk challenges comparisons of results and acute decision-making in trials. Deconvolution using an arterial input function has been hypothesized to generate maps of a more quantitative nature and with better prognostic value than simpler summary measures such as time-to-peak or the first moment of the concentration time curve. We sought to compare 10 different perfusion parameters by their ability to predict tissue infarction in acute ischemic stroke. Methods— In a retrospective analysis of 97 patients with acute stroke studied within 6 hours from symptom onset, we used receiver operating characteristics in a voxel-based analysis to compare 10 perfusion parameters: time-to-peak, first moment, cerebral blood volume and flow, and 6 variants of time to peak of the residue function and mean transit time maps. Subanalysis assessed the effect of reperfusion on outcome prediction. Results— The most predictive maps were the summary measures first moment and time-to-peak. First moment was significantly more predictive than time to peak of the residue function and local arterial input function-based methods (P<0.05), but not significantly better than conventional mean transit time maps. Conclusion— Results indicated that if a single map type was to be used to predict infarction, first moment maps performed at least as well as deconvolved measures. Deconvolution decouples delay from tissue perfusion; we speculate this negatively impacts infarct prediction.
Selectivity Estimation in Extensible Databases - A Neural Network Approach

Extensible database systems allow users to create new data types representing spatial, text, image, and other multimedia objects, and functions which operate on the new types[S96]. The new data types and functions can be used as predicates in SQL queries. Consider an insurance industry application, built using an extensible DBMS that has user defined extensions for spatial, text, date/time, and other business objects. The extensions support new data types such as point, circle, etc., and functions such as confains, interval, text-contains, etc. Let the tables Policies (policy-id, name, address, location, vehicle-type, . . .) and Claims (policy-id, claim-tag, accident-date, accident-location, accident-report, . . .) represent the partial schema containing both SQL’92 and user defined data types (UDTs). Consider a scenario in a targeted marketing application that requires a mailing list of all customers within 5 miles of point L, who have insured a ‘sports utility vehicle’ and were involved in a ‘rear-ended’ accident in the past 3 years. The corresponding SQL query would be: SELECT P.name, P.address FROM Policies P, Claims C WHERE coniuins(P.location, circle(L, 5)) AND P.vehicle type=“Sports Utility” AND P.policy-id = C.policy-id AND texl_contuins(C.accident-report, “rear-ended”) AND inietval(C.accident-date,current_date)<3 years
Short daily hemodialysis is associated with lower plasma FGF23 levels when compared with conventional hemodialysis.

BACKGROUND The utilization of short-term daily hemodialysis has increased over the last few years, but little is known on its effects on the control of serum phosphate and fibroblast growth factor 23 (FGF23) levels. METHODS We therefore performed a cross-sectional study to compare FGF23 levels as well as other biochemical variables between 24 patients undergoing short daily hemodialysis using the NxStage System® and 54 patients treated with conventional in-center hemodialysis. FGF23 levels were measured using the second-generation Immutopics® C-terminal assay. RESULTS Short daily hemodialysis patients were younger than patients on conventional hemodialysis but there were no differences between groups in the duration of end-stage renal disease nor in the number of patients with residual renal function. A greater number of short daily hemodialysis patients received vitamin D sterol therapy than did conventional in-center hemodialysis patients while there were no differences in the use of different phosphate binders and calcimimetic therapy between groups. Overall serum calcium, phosphorus and intact parathyroid hormone levels were similar between groups. While serum phosphorus levels correlated with FGF23 concentrations in each group separately [r=0.522 (P<0.01) and r=0.42 (P<0.01) in short daily and conventional in-center hemodialysis, respectively], FGF23 levels were lower [823 RU/mL (263, 2169)] in the patients receiving short daily hemodialysis than in patients treated with conventional hemodialysis [2521 RU/mL (909, 5556)] (P<0.01 between groups). CONCLUSIONS These findings demonstrate that FGF23 levels are significantly lower in short daily hemodialysis patients and suggest that FGF23 levels may be a more sensitive biomarker of cumulative phosphate burden than single or multiple serum phosphorus determinations in patients treated with hemodialysis.
Treatment of periodontitis and endothelial function.

BACKGROUND Systemic inflammation may impair vascular function, and epidemiologic data suggest a possible link between periodontitis and cardiovascular disease. METHODS We randomly assigned 120 patients with severe periodontitis to community-based periodontal care (59 patients) or intensive periodontal treatment (61). Endothelial function, as assessed by measurement of the diameter of the brachial artery during flow (flow-mediated dilatation), and inflammatory biomarkers and markers of coagulation and endothelial activation were evaluated before treatment and 1, 7, 30, 60, and 180 days after treatment. RESULTS Twenty-four hours after treatment, flow-mediated dilatation was significantly lower in the intensive-treatment group than in the control-treatment group (absolute difference, 1.4%; 95% confidence interval [CI], 0.5 to 2.3; P=0.002), and levels of C-reactive protein, interleukin-6, and the endothelial-activation markers soluble E-selectin and von Willebrand factor were significantly higher (P<0.05 for all comparisons). However, flow-mediated dilatation was greater and the plasma levels of soluble E-selectin were lower in the intensive-treatment group than in the control-treatment group 60 days after therapy (absolute difference in flow-mediated dilatation, 0.9%; 95% CI, 0.1 to 1.7; P=0.02) and 180 days after therapy (difference, 2.0%; 95% CI, 1.2 to 2.8; P<0.001). The degree of improvement was associated with improvement in measures of periodontal disease (r=0.29 by Spearman rank correlation, P=0.003). There were no serious adverse effects in either of the two groups, and no cardiovascular events occurred. CONCLUSIONS Intensive periodontal treatment resulted in acute, short-term systemic inflammation and endothelial dysfunction. However, 6 months after therapy, the benefits in oral health were associated with improvement in endothelial function.
Systematic review of stigma reducing interventions for African/Black diasporic women

Literature indicates that racism, sexism, homophobia and HIV‐related stigma have adverse impacts on health, well‐being, and quality of life among HIV‐positive women of African descent (African/Black diaspora). However, limited evidence exists on the effectiveness of interventions aimed at reducing stigma tailored for these women. This study systematically reviewed randomized controlled trials (RCTs), non‐randomized observational and quasi‐experimental studies evaluating the effectiveness of interventions aimed at reducing stigma experienced by this population.
Social Media as a Sphere for “Risky” Political Expression: A Twenty-Country Multilevel Comparative Analysis

In the context of the United States, research shows a positive relationship between network heterogeneity and political expression on social media at the individual level. This study builds on that research, relying on multilevel analysis that (1) leverages a twenty-country comparative survey and (2) includes country-level data on freedom of expression. Results show a positive relationship between network heterogeneity and political expression on social media across countries, but that relationship is stronger where freedom of expression is more limited.
Gradual Adjustment and Equilibrium Uniqueness Under Noisy Monitoring

We study the implications of flexible adjustment in strategic interactions using a class of finite-horizon models in continuous time. Players take costly actions to affect the evolution of state variables that are commonly observable and perturbed by Brownian noise. The values of these state variables influence players' terminal payoffs at the deadline, as well as their flow payoffs. In contrast to the static case, the equilibrium is unique under a general class of terminal payoff functions. Our characterization of the equilibrium builds on recent developments in the theory of backward stochastic differential equations (BSDEs). We use this tool to analyze applications, including team production, hold-up problems, and dynamic contests. In a team production model, the unique equilibrium selects an efficient outcome when frictions vanish.
Attractiveness, expertise and closeness: The effect of source credibility of the first lady as political endorser on social media in China

This study examines the strategies of political impression management adopted by the Weibo account Liyuan Fan Club from a source credibility perspective, investigating the capacity of each strategy in encouraging online political participation through measuring consumer’s online brand-related activities (i.e. consuming, contributing, and creating). In addition to traditional dimensions of source credibility (i.e. expertise and attractiveness), a new dimension, namely “closeness,” is added in based on previous studies in political branding and celebrity studies. A content analysis of 790 posts is conducted, in which the study finds that emphasis on Peng’s attractiveness and closeness have positive effects on participatory behaviors on social media, while emphasis on Peng’s expertise show no effect. Further analysis indicates that individual contributions of attractiveness and closeness on three levels of participatory behaviors are different, among which attractiveness is more effective in activating low-level participation, while closeness has more positive effect in encouraging high-level participation.
The ACS Survey of Galactic Globular Clusters. II. Stellar Evolution Tracks, Isochrones, Luminosity Functions, and Synthetic Horizontal-Branch Models

The ACS Survey of Galactic Globular Clusters, an HST Treasury Project, will deliver high-quality, homogeneous photometry of 65 globular clusters. This paper introduces a new collection of stellar evolution tracks and isochrones suitable for analyzing the ACS survey data. Stellar evolution models were computed at [Fe/H] = -2.5, -2.0, -1.5, -1.0, -0.5, and 0; [α/Fe] = -0.2, 0, 0.2, 0.4, 0.6, and 0.8; and three initial He abundances for masses from 0.1 to 1.8 M⊙ and ages from 2 to 15 Gyr. Each isochrone spans a wide range in luminosity, from MV ∼ 14 up to the tip of the red giant branch. These are complemented by a set of He-burning tracks that extend from the zero-age horizontal branch to the onset of thermal pulsations on the asymptotic giant branch. In addition, a set of computer programs are provided that make it possible to interpolate the isochrones in [Fe/H], generate luminosity functions from the isochrones, and create synthetic horizontal-branch models. The tracks and isochrones have been converted to the observational plane with two different color-Teff transformations, one synthetic and one semiempirical, in ground-based B, V, and I, and F606W and F814W for both ACS WFC and WFPC2 systems. All models and programs presented in this paper are available at the Dartmouth Stellar Evolution Database and the Multimission Archive at the Space Telescope Science Institute.
Mortality from Cancers of the Digestive System among Grand Multiparous Women in Taiwan

The aim of this study is to evaluate the significance of grand multiparous (GM) status in the mortality from cancers of the digestive system among a cohort of GM women in Taiwan during the period 1978–2008. The study cohort consisted of 144,922 women with at least five children (GM women) in the Taiwan Birth Register between 1 January 1978 and 31 December 2003. Standardized mortality ratios (SMRs) for cancers of the digestive system including esophagus, stomach, colon, rectum, liver, and pancreas were calculated by dividing the numbers of observed cancer deaths to the expected numbers of deaths based on the rates of national female population. Among the 144,922 GM women, a total of 23, 220, 213, 92, 397, and 65 deaths were caused by cancers of the esophagus, stomach, colon, rectum, liver, and pancreas, respectively. The SMRs among GM women were 1.61 (95% confidence intervals (CI): 0.95–2.27) for esophageal cancer, 1.15 (95% CI: 1.00–1.31) for stomach cancer, 1.07 (95% CI: 0.93–1.22) for colon cancer, 0.94 (95% CI: 0.75–1.14) for rectal cancer, 1.18 (95% CI: 1.06–1.30) for liver cancer, and 0.79 (95% CI: 0.60–0.98) for pancreatic cancer. This study provides evidence that grand multiparity may confer a protective effect on the risk of death from pancreatic cancer. However, the results suggest that GM women may increase the risk of death from cancers of the liver and stomach.
