The Effects of Teacher's Self-efficacy on Children's Sociality : The Serial Multiple Mediating Effects of Job-satisfaction and The Quality of Teacher-Child Interaction

ABSTRACT This study examined the effects of teacher's self-efficacy on children's sociality through the mediating effects of job-satisfaction and the quality of teacher-child interaction. The participants in this study consisted of 27 teachers working at child care centers and 71 children(4-5 years old) in their charge in Seoul and Gyeonggi-do province, Korea. Data were analyzed by means of a Hayes's PROCESS(2012) program to identify the serial multiple mediating effects and the relationships which exist among the various factors. The present study found that teacher's self-efficacy had significant indirect effects on children's sociality through job-satisfaction and the quality of teacher-child interaction. These results suggest that a higher level of teacher's self-efficacy leads to greater job-satisfaction and better quality of teacher-child interaction and this in turn has an influence on children's sociality.

Effects of Acute Phase Intensive Electrical Muscle Stimulation in Frail Elderly Patients With Acute Heart Failure (ACTIVE‐EMS): Rationale and protocol for a multicenter randomized controlled trial

In elderly patients with acute heart failure (AHF), clinical outcome is adversely affected by frailty. Although a number of potentially effective interventions for frailty have been reported, little is known about the effects of rehabilitation programs in frail elderly AHF patients. We postulated that addition of electrical muscle stimulation (EMS), which induces muscle contraction without requiring patient volition, to early rehabilitation would be efficacious in frail elderly AHF patients. The ACTIVE‐EMS (Effects of Acute Phase Intensive Electrical Muscle Stimulation in Frail Elderly Patients With AHF; UMIN000019551) trial is a multicenter, randomized controlled trial that will enroll 80 patients from 3 hospitals in Japan. AHF patients age ≥ 75 years positive for frailty, defined as Short Physical Performance Battery score 4 to 9, will be randomly assigned to receive early rehabilitation program only or EMS add‐on therapy for 2 weeks. The primary endpoint of the trial is the change in quadriceps isometric strength between baseline and 2 weeks, with changes in physical function and cognitive function, and clinical safety and feasibility of EMS therapy as secondary outcomes. ACTIVE‐EMS is the first randomized trial to evaluate the clinical effectiveness of adding EMS therapy to early rehabilitation in frail elderly AHF patients. The results of this study will provide insight for the development of appropriate rehabilitation programs for this high‐risk population.
Truly 3D midsagittal plane extraction for robust neuroimage registration

This paper describes a robust algorithm for reliable ideal midsagittal plane extraction (iMSP) from 3D neuroimages. The algorithm makes no assumptions about initial orientation of a given 3D brain image and works reliably on neuroimages of normal brains as well as brains with significant pathologies. Presented technique is truly three-dimensional since we treat each neuroimage as a three-dimensional volume rather than a set of two-dimensional slices. We use an edge-based approach which employs cross-correlation to extract iMSP. Proposed algorithm was quantitatively evaluated on a variety of real and artificial neuroimages. We find that our algorithm is able to extract iMSP from neuroimages with arbitrary initial orientations, large asymmetries, and low signal to noise ratio. We also demonstrate that presented algorithm can increase robustness of existing neuroimage registration algorithms, be it rigid, affine or less restricted deformable registration. Our algorithm was implemented using Insight Toolkit(ITK)
Uses and Gratifications and Exposure To Public Television

A consistent problem with uses and gratifications research has been the failure to distinguish between gratifications sought and gratifications obtained. This study tested a discrepancy model constrasting gratifications sought from television in general with gratifications respondents perceived they obtained (or would obtain) from public television. The model successfully predicted level of exposure to PTV content among respondents who made their own decisions concerning what programs to watch. Level of exposure was unrelated to the discrepancy measure among those who let others make the viewing decision. When each gratification was considered individually, the discrepancy model successfully discriminated between viewers and nonviewers of PTV on 8 of 11 gratification items. The results also indicate the importance of social determinants of the viewing decision and perceptions of PTV content as predictors of PTV consumption.
The controversial role of personality traits in entrepreneurial psychology

The usefulness of personality traits in the explanation and prediction of entrepreneurship is critically evaluated, and both contemporary theory and existing empirical findings are reviewed, emphasizing the need for conceptual clarity and methodological reform. Detailed recommendations for future research are outlined, and this critique is complemented by a detailed case study of a practical research design drawn from an ongoing project. Taken together, these provide a powerful illustration of how abstract principles can be used to inform research practices, and the underlying message emanating from this evolving body of knowledge can be used to enrich teaching materials and educational activities.
Scheduling of no-wait stochastic distributed assembly flowshop by hybrid PSO

Distributed assembly permutation flowshop problem (DAPFSP) is a typical NP-hard combinatorial optimization problem where N jobs are to be processed in the one of the F identical factories (processing stage) and then assembled into S final products by a single machine (assembly stage). In this study, we propose a new type of DAPFSP, i.e., the stochastic DAPFSP with no-wait constraint, in which the factories in the processing stage are characterized by flowshop with no-wait constraint between consecutive processing machines, meanwhile the time for processing and assembly is stochastic. To address the difficulties of the proposed scheduling model with respect to minimizing the makespan, we adapt the PSOSAHT algorithm framework proposed previously, where particle swarm optimization based exploration and simulated annealing based exploitation are well integrated, and the hypothesis test is to compare the stochastic makespan in statistical sense to avoid repeated search. Computational results on typical benchmark problems demonstrate the effectiveness and robustness of the PSOSAHT algorithm. It is worth noting that it is the first attempt to address the no-wait stochastic distributed assembly flowshop by hybrid PSO strategy.
Selected Studies in Uto-Aztecan Phonology

0. Introduction. I present in this article three separate studies of synchronic and historical Uto-Aztecan phonology. In the first, I examine the distribution of s and s in the Northern Uto-Aztecan language (itself a subfamily) Ttibatulabal and consider its consequences both for the synchronic analysis of that language and for typological and historical studies in general. I then compare the resulting description of the historical development of the Ttibatulabal fricatives with some features of the evolution of certain labials in the Southern Uto-Aztecan sub-
Sugar-mediated induction of Agrobacterium tumefaciens virulence genes: structural specificity and activities of monosaccharides

The virulence genes of Agrobacterium tumefaciens are induced by specific plant phenolic metabolites and sugars (G. A. Cangelosi, R. G. Ankenbauer, and E. W. Nester, Proc. Natl. Acad. Sci. USA, in press). In this report, monosaccharides, derivatives, and analogs which induce the vir regulon have been identified and the structural requirements for monosaccharide-mediated induction have been determined. Pyranose sugars with equatorial hydroxyls at C-1, C-2, and C-3 displayed strong vir gene-inducing activity; the C-4 hydroxyl could be epimeric and a wide variety of substitutions at C-5 were permissible. The acidic monosaccharide derivatives D-galacturonic acid and D-glucuronic acid were the strongest inducers among the monosaccharides tested. Eight of the 11 inducing compounds are known plant metabolites, and 7 are monomers of major plant cell wall polysaccharides. A role for monosaccharides and plant phenolic compounds as wound-specific plant metabolites which signal the ChvE/VirA/VirG regulatory system is proposed.
Skills and Vacancy Analysis with Data Mining Techniques

Through recognizing the importance of a qualified workforce, skills research has become one of the focal points in economics, sociology, and education. Great effort is dedicated to analyzing labor demand and supply, and actions are taken at many levels to match one with the other. In this work we concentrate on skills needs, a dynamic variable dependent on many aspects such as geography, time, or the type of industry. Historically, skills in demand were easy to evaluate since transitions in that area were fairly slow, gradual, and easy to adjust to. In contrast, current changes are occurring rapidly and might take an unexpected turn. Therefore, we introduce a relatively simple yet effective method of monitoring skills needs straight from the source—as expressed by potential employers in their job advertisements. We employ open source tools such as RapidMiner and R as well as easily accessible online vacancy data. We demonstrate selected techniques, namely classification with k-NN and information extraction from a textual dataset, to determine effective ways of discovering knowledge from a given collection of vacancies.
Running performance after adaptation to acutely intermittent hypoxia

Abstract To quantify the effects of adaptation to acutely intermittent hypoxia on running performance, we randomized 29 trained male hockey and soccer players in double-blind fashion to altitude or placebo groups for 15 days of daily use of a functional or placebo hypoxic re-breathing device. Each day's exposure consisted of alternately breathing stale and fresh air for 6 and 4 min respectively over 1 h. Oxygen saturation was monitored with pulse oximeters and progressively reduced in the hypoxia group (90% on Day 1, 77% on Day 15; equivalent to altitudes of ∼3600–6000 m above sea level). Performance tests were an incremental run to maximum speed followed by six maximal-effort running sprints; tests were performed 1 day before, 3 days after, and 12 days after the 15-day treatment. Relative to placebo, at 3 days post treatment the hypoxia group showed a mean increase in maximum speed of 2.0% (90% confidence limits, ±0.5%); sprint speed was relatively faster by 1.5% (±1.7%) in the first sprint through 7.0% (±1.5%) in the last; there were also substantial reductions in exercise lactate concentration and resting and exercise heart rate. Substantial effects on performance were still present 9 days later. Thus, adaptation to acutely intermittent hypoxia substantially improves high-intensity running performance.
A prospective comparison of cardiac magnetic resonance imaging and radionuclide ventriculography in the assessment of cardiac function in patients treated with anthracycline-based chemotherapy

PurposeTo compare cardiac MRI and radionuclide ventriculography (RVG) in cardiac monitoring during anthracycline (doxorubicin)-based chemotherapy. Materials and methodsWe studied 10 previously untreated adult non-Hodgkin lymphoma patients. Left ventricular ejection fraction (LVEF) was assessed by MRI and RVG simultaneously. In addition, left ventricular (LV) and left atrial size were determined by MRI. Both MRI and RVG measurements were determined at baseline and then repeated after eight cycles of CHOP chemotherapy (cumulative doxorubicin dose of 400 mg/m2). Power calculations were made on the basis of reproducibility measurements. ResultsClinical heart failure was not observed in any patient during the study. MRI detected a statistically significant increase in LV end-diastolic volume (128±39 vs. 151±46 ml, P<0.05) and LV mass (119±32 vs. 146±49 g, P<0.05) after doxorubicin therapy but no change in LVEF (46±8 vs. 47±11%, P=NS) or left atrial area. A significant LVEF reduction compared with baseline was observed by RVG (61±10 vs. 50±6%, P<0.01). On average, MRI resulted in 7±10% lower LVEF values compared with RVG. ConclusionRVG seems to be a valuable and repeatable tool in detecting early, subclinical deterioration in cardiac function and is the method of choice in the follow-up of LV function during anthracycline-based chemotherapy. Whether LV volumetric and mass changes found in MRI could predict later significant permanent cardiac damage should be evaluated in larger studies with long-term follow-up.
Classifying and Profiling Social Networking Site Users: A Latent Segmentation Approach

Social Networking Sites (SNSs) have showed an exponential growth in the last years. The first step for an efficient use of SNSs stems from an understanding of the individuals' behaviors within these sites. In this research, we have obtained a typology of SNS users through a latent segmentation approach, based on the frequency by which users perform different activities within the SNSs, sociodemographic variables, experience in SNSs, and dimensions related to their interaction patterns. Four different segments have been obtained. The "introvert" and "novel" users are the more occasional. They utilize SNSs mainly to communicate with friends, although "introverts" are more passive users. The "versatile" user performs different activities, although occasionally. Finally, the "expert-communicator" performs a greater variety of activities with a higher frequency. They tend to perform some marketing-related activities such as commenting on ads or gathering information about products and brands as well as commenting ads. The companies can take advantage of these segmentation schemes in different ways: first, by tracking and monitoring information interchange between users regarding their products and brands. Second, they should match the SNS users' profiles with their market targets to use SNSs as marketing tools. Finally, for most business, the expert users could be interesting opinion leaders and potential brand influencers.
Using Data Mining to Model Player Experience

Using data mining to analyze telemetry enables designers to measure player experience in games, providing quantitative measures. These measures can be used to implement telemetry-supported game design, where a human designer makes decisions with the support of insights learned from mining gameplay data. We model player retention as a measure of player experience and present a technique for identifying which gameplay elements have the most significant impact on this measurement. Our approach builds regression models and applies unique effect analysis to identify these features, which are then used to provide a designer with recommendations. We present two case studies applying this technique: Madden NFL 11 and Infinite Mario, and discuss how our results can be used to provide insights to the game designer.
Scalability of multiobjective genetic local search to many-objective problems: Knapsack problem case studies

It is well-known that Pareto dominance-based evolutionary multiobjective optimization (EMO) algorithms do not work well on many-objective problems. This is because almost all solutions in each population become non-dominated with each other when the number of objectives is large. That is, the convergence property of EMO algorithms toward the Pareto front is severely deteriorated by the increase in the number of objectives. Currently the design of scalable EMO algorithms is a hot issue in the EMO community. In this paper, we examine the scalability of multiobjective genetic local search (MOGLS) to many-objective problems using a hybrid algorithm of NSGA-lI and local search. Multiobjective knapsack problems with 2, 4, 6, 8, and 10 objectives are used in computational experiments. It is shown by experimental results that the performance of NSGA-lI is improved by the hybridization with local search independent of the number of objectives in the range of 2 to 10 objectives.
Creating mobile ad hoc workflows with Twitter

The wide-spread adoption of powerful mobile devices allows for the design of workflows while on the move. In this paper, we leverage established SOA principles towards mobility in design and execution. For this purpose, we introduce a lightweight Service workflow model that is tailored for the needs of ad-hoc creation and mobility. We show how sensor data from mobile devices can be included during the design of Service workflows and we address crowd sourcing aspects for the deployment and execution of Service workflows. We present a proof of concept prototype application that supports the creation of Service workflows on mobile devices.
Auditory Stimulus Timing Influences Perceived duration of Co-Occurring Visual Stimuli

There is increasing interest in multisensory influences upon sensory-specific judgments, such as when auditory stimuli affect visual perception. Here we studied whether the duration of an auditory event can objectively affect the perceived duration of a co-occurring visual event. On each trial, participants were presented with a pair of successive flashes and had to judge whether the first or second was longer. Two beeps were presented with the flashes. The order of short and long stimuli could be the same across audition and vision (audio–visual congruent) or reversed, so that the longer flash was accompanied by the shorter beep and vice versa (audio–visual incongruent); or the two beeps could have the same duration as each other. Beeps and flashes could onset synchronously or asynchronously. In a further control experiment, the beep durations were much longer (tripled) than the flashes. Results showed that visual duration discrimination sensitivity (d′) was significantly higher for congruent (and significantly lower for incongruent) audio–visual synchronous combinations, relative to the visual-only presentation. This effect was abolished when auditory and visual stimuli were presented asynchronously, or when sound durations tripled those of flashes. We conclude that the temporal properties of co-occurring auditory stimuli influence the perceived duration of visual stimuli and that this can reflect genuine changes in visual sensitivity rather than mere response bias.
Efficient Image Denoising Method Based on a New Adaptive Wavelet Packet Thresholding Function

This paper proposes a statistically optimum adaptive wavelet packet (WP) thresholding function for image denoising based on the generalized Gaussian distribution. It applies computationally efficient multilevel WP decomposition to noisy images to obtain the best tree or optimal wavelet basis, utilizing Shannon entropy. It selects an adaptive threshold value which is level and subband dependent based on analyzing the statistical parameters of subband coefficients. In the utilized thresholding function, which is based on a maximum a posteriori estimate, the modified version of dominant coefficients was estimated by optimal linear interpolation between each coefficient and the mean value of the corresponding subband. Experimental results, on several test images under different noise intensity conditions, show that the proposed algorithm, called OLI-Shrink, yields better peak signal noise ratio and superior visual image quality—measured by universal image quality index—compared to standard denoising methods, especially in the presence of high noise intensity. It also outperforms some of the best state-of-the-art wavelet-based denoising techniques.
Hearts Strangely Warmed (and Cooled): Emotional Experience in Religious and Atheistic Individuals

In light of neurophysiological evidence suggesting a link between hemispheric dominance and religious preference, three studies tested whether atheists and religious individuals process emotions differently. Suggestive of right-hemispheric dominance, individuals who identified with religion reported more intense positive emotions associated with a recalled love experience (Study 1), greater sadness in immediate response to reading a tragic news story (Study 2), and more vivid recall of the subjective details of either their most recent birthday or an existential crisis (Study 3). They also reported greater alexithymia compared to atheists. Overall, agnostic/no religion individuals averaged in between these two groups. The results suggest that, relative to atheists, religious individuals have more accessible yet undifferentiated emotions, which may perhaps serve as raw materials for religious experience.
Induction of Sp1 in Differentiating Human Embryonal Carcinoma Cells Triggers Transcription of the Fibronectin Gene

ABSTRACT Cells of the human embryonal carcinoma line NEC14 proliferate as densely packed clusters consisting of small, polygonal stem cells and do not express a detectable level of fibronectin (FN). Upon induction of differentiation by treatment withN,N′-hexamethylene bisacetamide (HMBA), the level of FN mRNA increased steeply within 24 h and FN began to be accumulated, along with the organization of actin filaments in the cells. The FN promoter elements required for the activation were analyzed in reference to a cluster of GC boxes by using the chloramphenicol acetyltransferase (CAT) gene fused to 5′ sequential-deletion derivatives of the promoter and promoters carrying base substitutions in the GC boxes. Among four GC boxes, GC boxes 2 and 3 had the greatest effect on promoter activation, and base substitutions in these GC boxes resulted in 80% reduction in promoter activity. The pattern of DNA-protein complex formation with these GC boxes changed drastically after induction of differentiation. The extract prepared from undifferentiated NEC14 cells formed fast-migrating complexes (UnD complexes), while the extract prepared from NEC14 cells treated with HMBA for 24 h formed slow-migrating complexes containing Sp1. Both complexes were formed predominantly with GC box 2. Base substitutions within the GC boxes completely abolished the formation of both UnD and Sp1 complexes. Consistent with these changes, the Sp1 level increased steeply within 24 h. Induction of Sp1 expression in NEC14 cells effectively stimulated the promoter activity of the transfected FN promoter-CAT constructs. These results indicate that activation of the FN promoter in differentiating NEC14 cells occurs by the steep induction of Sp1, which prevents an undifferentiated cell factor from binding to the Sp1 sites.
