An Investigation of the Overlap Among Disinhibited Eating Behaviors in Children and Adolescents

Abstract : Eating- and weight-related problems represent a significant public health threat among children and adolescents. The identification of common risk factors promoting obesity and eating disorders in youth may enhance prevention and early intervention efforts. Three pediatric disinhibited eating behaviors-eating in the absence of hunger, emotional eating, and loss of control eating-appear to elevate risk for eating disorder psychopathology, general psychopathology, and weight problems among children and adolescents. Despite their theoretical similarities, studies have yet to examine the overlap among all three disinhibited eating behaviors between youth. A systematic evaluation may lead to the identification of behavioral risk profiles that providers may be able to screen for and make predictions about based on correlates of these subtypes. Therefore, the objectives ofthe current study were to: 1) determine whether children and adolescent scan be classified into subtypes based on the overlap of disinhibited eating behaviors; and 2) investigate the validity and clinical utility of subtypes based on the overlap of disinhibited eating behaviors among children and adolescents.
How Gender Conditions the Way Citizens Evaluate and Engage with Their Representatives

Scholars argue that women’s presence in politics enhances symbolic representation, such as positive evaluations of one’s representative and increased political engagement. However, there is little empirical evidence of these symbolic benefits from descriptive representation. With data from the Cooperative Congressional Election Study panel survey, we examine how a change in the gender of a representative affects individuals’ perceptions of that representative and likelihood to contact them. In general, we find that women express more positive evaluations of female representatives than male representatives, yet they are also less likely to contact female representatives. By contrast, the effect of an elected official’s gender does not significantly affect how men evaluate or engage with that official. However, we also show that partisanship conditions these effects, perhaps due to the fact that gender stereotypes operate differently for Democrats than Republicans. For example, women rate female Republican legislators more positively than they do male Republican legislators, but neither women nor men rate Democratic legislators differently based on their gender. The findings provide strong evidence that gender matters when it comes to representation, but contrary to some conventional wisdom, female elected officials may actually enjoy some advantages in terms of their standing among constituents.
The Central Engines of 19 LINERs as Viewed by Chandra

Using archival Chandra observations of 19 LINERs, we explore the X-ray properties of their inner kiloparsec to determine the origin of their nuclear X-ray emission, to investigate the presence of an AGN, and to identify the power source of the optical emission lines. The relative numbers of LINER types in our sample are similar to those in optical spectroscopic surveys. We find that diffuse, thermal emission is very common and is concentrated within the central few hundred parsecs. The average spectra of the hot gas in spiral and elliptical galaxies are very similar to those of normal galaxies. They can be fitted with a thermal plasma (kT ~ 0.5 keV) plus a power-law (photon index of 1.3-1.5) model. There are on average three detected point sources in their inner kiloparsec with 1037 ergs s-1 < L0.5-10 keV < 1040 ergs s-1. The average cumulative luminosity functions for sources in spiral and elliptical galaxies are identical to those of normal galaxies. In the innermost circle of 2. ″5 radius in each galaxy we find an AGN in 12 of the 19 galaxies. The AGNs contribute a median of 60% of the 0.5-10 keV luminosity of the central 2. ″5 region, and they have luminosities of 1037-1039 ergs s-1 (Eddington ratios of 10-8 to 10-5). The ionizing luminosity of the AGNs is not enough to power the observed optical emission lines in this particular sample. Thus, we suggest that the lines are powered either by the mechanical interaction of an AGN jet (or wind) with the circumnuclear gas or by stellar processes, such as photoionization by post-AGB stars from an old or intermediate-age population (in most cases) or by young stars (in a few cases).
Co-designing with relationships in mind

We need to move from object-oriented thinking towards relational thinking for many reasons. As public services become more complex, their design increasingly focuses on the relationships between people. The role of the traditional service staff is shifting from a ‘provider’ to an ‘enabler’ and ‘facilitator’ of relationships between service users, their peers, family or members of the civil service. Many agree that the future of public services relies on relational services, relational welfare and a relational state. Yet we don’t have a shared vocabulary to describe good relationships nor materials to design for services that support meaningful relationships. We visually perceive the world as fragmented parts rather than seeing the connection amongst the parts. This perception is integrated with cognition, therefore when mapping complex systems, nodes are emphasized over their relations in-between. Categorizing and color-coding types of systemic relations are useful to understand but not sufficient to shape complex social relationships. We propose a multi-sensory relational tool that aids public servants, designers and users in understanding social relationships through the use of material properties as new design materials. Testing this tool revealed that people are enabled, within a short timeframe, to create a shared relational vocabulary and use the tool to co-design new service concepts. However, future research needs to address how to move from theory to practice, hence from concepts to prototyping.
GamingAnywhere: an open cloud gaming system

Cloud gaming is a promising application of the rapidly expanding cloud computing infrastructure. Existing cloud gaming systems, however, are closed-source with proprietary protocols, which raises the bars to setting up testbeds for experiencing cloud games. In this paper, we present a complete cloud gaming system, called GamingAnywhere, which is to the best of our knowledge the first open cloud gaming system. In addition to its openness, we design GamingAnywhere for high extensibility, portability, and reconfigurability. We implement GamingAnywhere on Windows, Linux, and OS X, while its client can be readily ported to other OS's, including iOS and Android. We conduct extensive experiments to evaluate the performance of GamingAnywhere, and compare it against two well-known cloud gaming systems: OnLive and StreamMyGame. Our experimental results indicate that GamingAnywhere is efficient and provides high responsiveness and video quality. For example, GamingAnywhere yields a per-frame processing delay of 34 ms, which is 3+ and 10+ times shorter than OnLive and StreamMyGame, respectively. Our experiments also reveal that all these performance gains are achieved without the expense of higher network loads. The proposed GamingAnywhere can be employed for setting up cloud gaming testbeds, which, we believe, will stimulate more research innovations on cloud gaming systems.
Teacher Language Awareness Revisited: An Exploratory Study of the Level and Nature of Language Awareness of Prospective Iranian English Teachers

A teacher's language awareness (TLA) is generally believed to exert a tremendous influence on language instruction. However, reviewing literature revealed that it has not received due attention in teacher training centers in Iran. Therefore, this paper reports on an investigation into the metalinguistic awareness of prospective teachers at Teacher Education Universities of Iran training to be junior and senior high school English teachers. The study focuses on the test performance of these prospective teachers as an indication of their explicit knowledge base and also the relationship between the metalinguistic knowledge and their error identification capability. To that end, a metalinguistic knowledge test (MKT) and a grammaticality judgment test (GJT) were administered to 207 student teachers to canvass the nature and extent of their repertoire of explicit knowledge about language and of grammatical terminologies as part of their TLA. The results revealed a moderate level of metalinguistic knowledge and a significant relationship between metalinguistic knowledge and error identification ability. Moreover, the findings of the study shed light on the prominence of metalinguistic knowledge as a means of improving teachers' linguistic proficiency, detected the lacunae in student teachers' knowledge about language and signaled the need for improvement in prospective teachers' metalinguistic knowledge.
Green synthesis of copper oxide nanoparticles using gum karaya as a biotemplate and their antibacterial application

Background Copper oxide (CuO) nanoparticles have attracted huge attention due to catalytic, electric, optical, photonic, textile, nanofluid, and antibacterial activity depending on the size, shape, and neighboring medium. In the present paper, we synthesized CuO nanoparticles using gum karaya, a natural nontoxic hydrocolloid, by green technology and explored its potential antibacterial application. Methods The CuO nanoparticles were synthesized by a colloid-thermal synthesis process. The mixture contained various concentrations of CuCl2 • 2H2O (1 mM, 2 mM, and 3 mM) and gum karaya (10 mg/mL) and was kept at 75°C at 250 rpm for 1 hour in an orbital shaker. The synthesized CuO was purified and dried to obtain different sizes of the CuO nanoparticles. The well diffusion method was used to study the antibacterial activity of the synthesized CuO nanoparticles. The zone of inhibition, minimum inhibitory concentration, and minimum bactericidal concentration were determined by the broth microdilution method recommended by the Clinical and Laboratory Standards Institute. Results Scanning electron microscopy analysis showed CuO nanoparticles evenly distributed on the surface of the gum matrix. X-ray diffraction of the synthesized nanoparticles indicates the formation of single-phase CuO with a monoclinic structure. The Fourier transform infrared spectroscopy peak at 525 cm−1 should be a stretching of CuO, which matches up to the B2u mode. The peaks at 525 cm−1 and 580 cm−1 indicated the formation of CuO nanostructure. Transmission electron microscope analyses revealed CuO nanoparticles of 4.8 ± 1.6 nm, 5.5 ± 2.5 nm, and 7.8 ± 2.3 nm sizes were synthesized with various concentrations of CuCl2 • 2H2O (1 mM, 2 mM, and 3 mM). X-ray photoelectron spectroscopy profiles indicated that the O 1s and Cu 2p peak corresponding to the CuO nanoparticles were observed. The antibacterial activity of the synthesized nanoparticles was tested against Gram-negative and positive cultures. Conclusion The formed CuO nanoparticles are small in size (4.8 ± 1.6 nm), highly stable, and have significant antibacterial action on both the Gram classes of bacteria compared to larger sizes of synthesized CuO (7.8 ± 2.3 nm) nanoparticles. The smaller size of the CuO nanoparticles (4.8 ± 1.6 nm) was found to be yielding a maximum zone of inhibition compared to the larger size of synthesized CuO nanoparticles (7.8 ± 2.3 nm). The results also indicate that increase in precursor concentration enhances an increase in particle size, as well as the morphology of synthesized CuO nanoparticles.
HOLOCENE FIRE HISTORY OF A COASTAL TEMPERATE RAIN FOREST BASED ON SOIL CHARCOAL RADIOCARBON DATES

The long-term role of fire in coastal temperate rain forest is poorly under- stood. To determine the historical role of fire on western Vancouver Island (British Co- lumbia, Canada), we constructed a long-term spatially explicit fire history and examined the spatial and temporal distribution of fire during the Holocene. Two fire-history parameters (time-since-fire (TSF) and fire extent) were related to three landscape parameters (landform (hill slope or terrace), aspect, and forest composition) at 83 sites in a 730-ha low-elevation (less than ;200 m) area of a mountainous watershed. We dated fires using tree rings (18 sites) and 120 soil-charcoal radiocarbon dates (65 sites). Comparisons among multiple radiocarbon dates indicated a high probability that the charcoal dated at each site represented the most recent fire, though we expect greater error in TSF estimates at sites where charcoal was very old (.6000 yr) and was restricted to mineral soil horizons. TSF estimates ranged from 64 to ;12 220 yr; 45% of the sites have burned in the last 1000 yr, whereas 20% of the sites have not burned for over 6000 yr. Differences in median TSF were more significant between landform types or across aspects than among forest types. Median TSF was sig- nificantly greater on terraces (4410 yr) than on hill slopes (740 yr). On hill slopes, all south-facing and southwest-facing sites have burned within the last 1000 yr compared to only 27% of north- and east-facing sites burning over the same period. Comparison of fire dates among neighboring sites indicated that fires rarely extended . 250 m. During the late Holocene, landform controls have been strong, resulting in the bias of fires to south-facing hillslopes and thus allowing late-successional forest structure to persist for thousands of years in a large portion of the watershed. In contrast, the early Holocene regional climate and forest composition likely resulted in larger landscape fires that were not strongly controlled by landform factors. The millennial-scale TSF detected in this study supports the distinction of coastal temperate rain forest as being under a fundamentally different disturbance regime than other Pacific Northwest forests to the east and south.
Antecedents of Generalized Computer Self-Efficacy Judgements

Computer self-efficacy is frequently used as an explanatory variable in software training and technology acceptance investigations and it has been frequently used to predict training and learning outcomes. While self-efficacy models identify prior experience with computers as an important determinant of generalized self-efficacy judgments, relatively few studies have systematically examined the types of experience that drive such judgments. Gender and frequency of computer use have also been identified as other predictors of generalized computer self-efficacy. In this investigation, self-reported knowledge/skill attainments levels with each of nineteen computer use/knowledge dimensions are used to measure prior experience/knowledge of computers. These were collected from 340 university students at the same time that they completed a generalized computer self-efficacy scale. This data is used to test two predictions: 1) that greater prior computer knowledge/experience is directly related to higher computer self-efficacy scores and 2) for comparable levels of prior experience/knowledge, males will have higher self-efficacy scores than females. Our results provide support for the first prediction but not the second. Our findings suggest that experience/knowledge of less common computer applications may be more important in shaping self-efficacy judgments than are greater levels of experience/knowledge with common computer applications.
Stress evolution in Si during low-energy ion bombardment

Measurements of stress evolution during low-energy argon ion bombardment of Si have been made using a real-time wafer curvature technique. During irradiation, the stress reaches a steady-state compressive value that depends on the flux and energy. Once irradiation is terminated, the measured stress relaxes slightly in a short period of time to a final value. To understand the ion-induced stress evolution and relaxation mechanisms, we account for the measured behavior with a model for viscous relaxation that includes the ion-induced generation and annihilation of flow defects in an amorphous Si surface layer. The analysis indicates that bimolecular annihilation (i.e., defect recombination) is the dominant mechanism controlling the defect concentration both during irradiation and after the cessation of irradiation. From the analysis, we determine a value for the fluidity per flow defect.
On the wintertime low bias of Northern Hemisphere carbon monoxide found in global model simulations

Abstract. Despite the developments in the global modelling of chemistry and of the parameterization of the physical processes, carbon monoxide (CO) concentrations remain underestimated during Northern Hemisphere (NH) winter by most state-of-the-art chemistry transport models. The consequential model bias can in principle originate from either an underestimation of CO sources or an overestimation of its sinks. We address both the role of surface sources and sinks with a series of MOZART (Model for Ozone And Related Tracers) model sensitivity studies for the year 2008 and compare our results to observational data from ground-based stations, satellite observations, and vertical profiles from measurements on passenger aircraft. In our base case simulation using MACCity (Monitoring Atmospheric Composition and Climate project) anthropogenic emissions, the near-surface CO mixing ratios are underestimated in the Northern Hemisphere by more than 20 ppb from December to April, with the largest bias of up to 75 ppb over Europe in January. An increase in global biomass burning or biogenic emissions of CO or volatile organic compounds (VOCs) is not able to reduce the annual course of the model bias and yields concentrations over the Southern Hemisphere which are too high. Raising global annual anthropogenic emissions with a simple scaling factor results in overestimations of surface mixing ratios in most regions all year round. Instead, our results indicate that anthropogenic CO and, possibly, VOC emissions in the MACCity inventory are too low for the industrialized countries only during winter and spring. Reasonable agreement with observations can only be achieved if the CO emissions are adjusted seasonally with regionally varying scaling factors. A part of the model bias could also be eliminated by exchanging the original resistance-type dry deposition scheme with a parameterization for CO uptake by oxidation from soil bacteria and microbes, which reduces the boreal winter dry deposition fluxes. The best match to surface observations, satellite retrievals, and aircraft observations was achieved when the modified dry deposition scheme was combined with increased wintertime road traffic emissions over Europe and North America (factors up to 4.5 and 2, respectively). One reason for the apparent underestimation of emissions may be an exaggerated downward trend in the Representative Concentration Pathway (RCP) 8.5 scenario in these regions between 2000 and 2010, as this scenario was used to extrapolate the MACCity emissions from their base year 2000. This factor is potentially amplified by a lack of knowledge about the seasonality of emissions. A methane lifetime of 9.7 yr for our basic model and 9.8 yr for the optimized simulation agrees well with current estimates of global OH, but we cannot fully exclude a potential effect from errors in the geographical and seasonal distribution of OH concentrations on the modelled CO.
Cardiac coherence, self-regulation, autonomic stability, and psychosocial well-being

The ability to alter one’s emotional responses is central to overall well-being and to effectively meeting the demands of life. One of the chief symptoms of events such as trauma, that overwhelm our capacities to successfully handle and adapt to them, is a shift in our internal baseline reference such that there ensues a repetitive activation of the traumatic event. This can result in high vigilance and over-sensitivity to environmental signals which are reflected in inappropriate emotional responses and autonomic nervous system dynamics. In this article we discuss the perspective that one’s ability to self-regulate the quality of feeling and emotion of one’s moment-to-moment experience is intimately tied to our physiology, and the reciprocal interactions among physiological, cognitive, and emotional systems. These interactions form the basis of information processing networks in which communication between systems occurs through the generation and transmission of rhythms and patterns of activity. Our discussion emphasizes the communication pathways between the heart and brain, as well as how these are related to cognitive and emotional function and self-regulatory capacity. We discuss the hypothesis that self-induced positive emotions increase the coherence in bodily processes, which is reflected in the pattern of the heart’s rhythm. This shift in the heart rhythm in turn plays an important role in facilitating higher cognitive functions, creating emotional stability and facilitating states of calm. Over time, this establishes a new inner-baseline reference, a type of implicit memory that organizes perception, feelings, and behavior. Without establishing a new baseline reference, people are at risk of getting “stuck” in familiar, yet unhealthy emotional and behavioral patterns and living their lives through the automatic filters of past familiar or traumatic experience.
A Traceability Conjecture for Oriented Graphs

A (di)graph $G$ of order $n$ is $k$-traceable (for some $k$, $1\leq k\leq n$) if every induced sub(di)graph of $G$ of order $k$ is traceable. It follows from Dirac's degree condition for hamiltonicity that for $k\geq2$ every $k$-traceable graph of order at least $2k-1$ is hamiltonian. The same is true for strong oriented graphs when $k=2,3,4,$ but not when $k\geq5$. However, we conjecture that for $k\geq2$ every $k$-traceable oriented graph of order at least $2k-1$ is traceable. The truth of this conjecture would imply the truth of an important special case of the Path Partition Conjecture for Oriented Graphs. In this paper we show the conjecture is true for $k \leq 5$ and for certain classes of graphs. In addition we show that every strong $k$-traceable oriented graph of order at least $6k-20$ is traceable. We also characterize those graphs for which all walkable orientations are $k$-traceable.
Differentiation of Central Lung Cancer from Atelectasis: Comparison of Diffusion-Weighted MRI with PET/CT

Objective Prospectively assess the performance of diffusion-weighted magnetic resonance imaging (DW-MRI) for differentiation of central lung cancer from atelectasis. Materials and Methods 38 consecutive lung cancer patients (26 males, 12 females; age range: 28–71 years; mean age: 49 years) who were referred for thoracic MR imaging examinations were enrolled. MR examinations were performed using a 1.5-T clinical scanner and scanning sequences of T1WI, T2WI, and DWI. Cancers and atelectasis were measured by mapping of the apparent diffusion coefficients (ADCs) obtained with a b-value of 500 s/mm2. Results PET/CT and DW-MR allowed differentiation of tumor and atelectasis in all 38 cases, but T2WI did not allow differentiation in 9 cases. Comparison of conventional T2WI and DW-MRI indicated a higher contrast noise ratio of the central lung carcinoma than the atelectasis by DW-MRI. ADC maps indicated significantly lower mean ADC in the central lung carcinoma than in the atelectasis (1.83±0.58 vs. 2.90±0.26 mm2/s, p<0.0001). ADC values of small cell lung carcinoma were significantly greater than those from squamous cell carcinoma and adenocarcinoma (p<0.0001 for both). Conclusions DW-MR imaging provides valuable information not obtained by conventional MR and may be useful for differentiation of central lung carcinoma from atelectasis. Future developments may allow DW-MR imaging to be used as an alternative to PET-CT in imaging of patients with lung cancer.
