Exploring the sociocultural pathway model as it predicts body satisfaction in athletes and nonathletes

This study was a secondary data analysis in which the sociocultural pathway model (Stice & Agras, 1998) was tested in male and female athletes and nonathletes. There were three primary purposes for this study. The first aim was to test the applicability of the sociocultural model theory in the current sample by conducting confirmatory factor analyses on the measurement constructs. The second aim was to create a structural equation model that fit the data best according to theoretical directionality of the constructs in the sociocultural theory. The third aim was to compare the predictive paths of this model across sexes and athlete subgroups. The sample (N=543) was composed of competitive athletes (n=56), recreational athletes (n=192), and non-athletes (n=294) who completed an online questionnaire measuring the major components of the sociocultural pathway model. Construct means were examined in nonathletes and athletes of both sexes using two-way multivariate analysis of variance, follow-up two-way analyses of variance, and post-hoc Tukey HSD tests. Confirmatory factor analyses were run on the original factor structures of each construct and found model fit to be poor. Measures were revised, cutting poorly loading items and confirmatory factor analyses were conducted on revised measures, finding model fit to be adequate. A structural equation model predicting body satisfaction from the internalization of thin ideals, negative affect, positive affect, and perfectionism had low-adequate fit in the sample. Comparisons of the predictive model revealed that the model fit to be adequate across group. Findings suggest the field is in need of improved operational definitions and more psychometrically sound measures of body satisfaction. Attention to measurement of other constructs of the sociocultural pathway model is also warranted. Future research should examine measurement structures and invariance across a range of minority groups, as well as longitudinal models to test and expand the applicability of this model of eating disorders prevention.
Voluntary Disclosure as a Response to Low Accounting Quality: Evidence from Quarterly Conference Call Usage

Quarterly conference calls immediately following the release of earnings information have become an important means of voluntary disclosure over the past few years. This paper uses the quarterly conference call as a disclosure metric to examine whether firms respond to low accounting quality by providing more voluntary disclosure. After controlling for other characteristics of a firm's information environment, I find that there is a significant negative relation between measures of the quality of a firm's financial statement information and the likelihood that the firm will use a quarterly conference call. This finding is consistent with the hypothesis in Verrecchia (1990) that the probability of disclosure of management's private information is inversely related to the quality of the prior public information on firm value.
Simple ZVT PWM single-phase rectifier with reduced conduction loss and unity power factor

This paper proposes a simple unify power factor zero-voltage-transition (ZVT) pulse-width-modulated (PWM) single-phase rectifier, which features reduced switching and conduction losses. The switching loss reduction is achieved by a simple auxiliary commutation circuit, and the conduction loss reduction is achieved by employing a single-stage converter, rather than a typical double-stage converter comprising of a front-end rectifier and a boost rectifier Furthermore, thanks to good features such as simple PWM control at constant frequency, low switch stress, low VAR rating of commutation circuits, and simple power circuit structure, it is suitable for high power applications. The principle of operation is explained in detail, and major characteristics analysis and experimental results of the new converter are also included.
The Evolutionary Establishment of Apomixis in Hybrids of the Ranunculus auricomus Complex: Developmental and Cytogenetic Studies

In plant evolution, polyploidization and hybridization are important forces that both effectively contribute to developmental alterations. Asexual seed formation, known as apomixis, is mainly found in polyploid and/ or hybrid species but how these factors trigger the functional activation of apomictic reproduction remains elusive. The Ranunculus auricomus complex is worldwide distributed and consists almost exclusively of polyploid apomictic and a very small number of diploid and tetraploid sexual species. Due to the presence of sexual and apomictic species, this complex is an adequate model system to study the establishment and evolution of apomixis in natural plant populations. In this study, synthetically derived young diploid and polyploid Ranunculus hybrids, including their parental species were used for detailed microscopic investigations of their flow of male and female gametophyte development. In both, micro- and megasporogenesis multiple abnormalities were discovered. Female development in diploid F2 hybrids showed significantly enhanced frequencies of aposporous initial cell formation, which is associated with strong genomic dosage effects. These effects are considered to be the consequence of both F1 parent plants being aposporous. Analyses of seed formation revealed beside sexually formed seeds, several intermediate BIII seeds as well as a few completely apomictic ones. In agree with this, male development showed severe irregularities in meiotic cell division and in sporogenesis. Especially, allopolyploid plants performed significantly more abnormal than homoploids. The error frequency in diploid F2 Ranunculus hybrids was significantly higher as in the F1 or in the parental generation. Furthermore, meiosis in female plant organs was significantly more prone to severe alterations than in male. All these results indicate that hybridization, rather than polyploidization, is the apomixis-triggering factor in synthetic Ranunculus plants. In addition, the disturbed course of meiosis in micro- and megasporogenesis caused major implications in the female development, while on the male side only minor consequences were observed. These observations indicate strong, selective pressure acting on female development, whereas male gametophyte formation appears to be more or less unaffected. The switch to asexual seed formation in young, diploid Ranunculus hybrids is a rescue from imminent hybrid sterility, which is assumed to be caused by disturbed female meiosis.
User-oriented mobility management in cellular wireless networks

USER-ORIENTED MOBILITY MANAGEMENT IN CELLULAR WIRELESS NETWORKS Mobility Management (MM) in wireless mobile networks is a vital process to keep an individual User Equipment (UE) connected while moving within the network coverage area—this is required to keep the network informed about the UE’s mobility (i.e., location changes). The network must identify the exact serving cell of a specific UE for the purpose of data-packet delivery. The two MM procedures that are necessary to localize a specific UE and deliver data packets to that UE are known as Tracking Area Update (TAU) and Paging, which are burdensome not only to the network resources but also UE’s battery—the UE and network always initiate the TAU and Paging, respectively. These two procedures are used in current Long Term Evolution (LTE) and its next generation (5G) networks despite the drawback that it consumes bandwidth and energy. Because of potentially very high-volume traffic and increasing density of high-mobility UEs, the TAU/Paging procedure incurs significant costs in terms of the signaling overhead and the power consumption in the battery-limited UE. This problem will become even worse in 5G, which is expected to accommodate exceptional services, such as supporting mission-critical systems (closeto-zero latency) and extending battery lifetime (10 times longer). This dissertation examines and discusses a variety of solution schemes for both the TAU and Paging, emphasizing a new key design to accommodate 5G use cases. However, ongoing efforts are still developing new schemes to provide seamless connections to the ever-increasing density of high-mobility UEs. In this context and toward achieving 5G use cases, we propose a novel solution to solve the MM issues, named gNB-based UE Mobility Tracking (gNB-based UeMT). This solution has four features aligned with achieving 5G goals. First, the mobile UE will no longer trigger the TAU to report their location changes, giving much more power savings with no signaling overhead. Instead, second, the network elements, gNBs, take over the responsibility of Tracking and Locating
Effect of interchannel mismatches upon adaptive array cancellation

The author analyzes the effect of interchannel mismatch on adaptive array interference cancellation for an arbitrary number of channels and arbitrary bandwidth waveforms for a partially adaptive array used in a multiple sidelobe canceller (MSLC). A general equation giving the residue power as a function of the interchannel mismatch, the radar bandwidth, and the array parameters is derived. To aid in clarifying the dependence of cancellation on interchannel errors, a Taylor series expansion is obtained. It shows that the ratio of adapted power to the unadapted main power is greater than 1- mu (where mu is the average interchannel mismatch correlation coefficient) for all interferer locations and power levels and any number of auxiliary antennas. The special, simple-geometry case of narrowband orthogonal direction vectors is evaluated. For this case, the ratio of adapted to unadapted power is approximately equal to (1- mu )(1+K/N) for K interferers and N auxiliary antennas. <<ETX>>
INFLUÊNCIA DA CONCENTRAÇÃO DO LEITE NA REOLOGIA DO QUEIJO TIPO PRATO INFLUENCY OF CONCENTRATION OF MILK IN THE REOLOGY OF THE PRATO CHEESE

The objective of this work was study the physical behavior and viscoelastic of the Prato cheese confectioned with milk daily skimmed in diverse concentrations. Have produced intent of daily skimmed milk solid texts of 17,3% and 28,7% using the concentrator Stephan Geiger and with milk without concentrating with 10% solid text. With these milk Prato cheese was confectioned. Compression and decompression of the cheeses had been studied. One approximately generated bodies of test of 20 millimeters of height. The test bodies had been made use on aluminum plates and on the set steel cylinders of masses 50, 100 and 150 grams had been used. The same ones had remained under compression 870 minutes, had been after submitted to the decompression of 460 minutes. During this time they had been carried through measured of the height. One got with these data values of the Young's moduli, Coefficient of Poisson, Compressibility and Moduli of rigidity. It can be verified that how much bigger the tension applied on the lesser was the cheese elastic recovery. The permanent deformation was dominant front to the elastic.
Environmental Disclosure Practices in Annual Report of the Listed Textile Industries in Bangladesh

The present study is a critical examination of the environmental disclosure practices and extent of disclosure of listed textile industries in Bangladesh. The study reveals that more than two-third (69%) of the sample companies addressed no environmental issues in their annual reports and on an average textile industries disclosed very poor information regarding environmental aspects where variation of disclosure among the industries is considerably high. The study recommends Government and other regulatory authorities taking necessary steps in compelling and motivating all textile companies in Bangladesh in addressing environmental issues in their annual report. Finally, the study expects playing important role in creating consciousness among the users and preparers in disclosing more environmental information in annual reports.
Sensitivity of Hopf bifurcations to power system parameters

Formulas for the sensitivity of the Hopf loading margin with respect to any power system parameter are presented. These first-order sensitivities determine an optimum direction in parameter space for changing parameters to increase the loading margin. The Hopf bifurcation sensitivities of a simple power system with a voltage regulator and a dynamic load model are computed. Parameter sensitivities of the Hopf and saddle node bifurcations are compared. An idea for eliminating some Hopf bifurcations is presented. <<ETX>>
Collisionless dynamics in globular clusters

Since globular clusters (GCs) are old, low-N systems their dynamics is widely believed to be fully dominated by collisional two-body processes and their surface brightness profiles are fitted by King models. However, for many GCs, especially those with Hubble Space Telescope-resolved central regions and ‘extratidal’ features, King models provide poor fits. We suggest that this is partly because collisionless dynamics is also important and contributes to shaping the cluster properties. We show using time-scale and length-scale arguments that except for the very centres of clusters, collisionless dynamics should be more important than collisional. We then fit 38 GCs analysed by Noyola & Gebhardt with (collisional) King and (collisionless) DARKexp models over the full available radial range, and find that the latter provide a better fit to 29 GCs; for six of these the fit is at least approximately five times better in terms of rms. DARKexp models are theoretically derived maximum entropy equilibrium states of self-gravitating collisionless systems and have already been shown to fit the results of dark matter N-body simulations. (We do not attempt fits with ad hoc fitting functions.)
Water Stress and Agriculture

Climate changes and water availability cause an important impact in agriculture, food disposal and consequently in human health. According to the U.S. Census Bureau, the total population of the World is now over 7,032 billion, and all growth projections for developed and undeveloped countries show that a total of 9 million of inhabitants will be reached before 2050. As a result, the demand for food and fuel will increase signifi‐ cantly. How agriculture will move on to guarantee continuous provision of food for all inhabitants of the planet?
Magneto-transport of large CVD-grown graphene

We present magnetoresistance measurements on large scale monolayer graphene grown by chemical vapor deposition (CVD) on copper. The graphene layer was transferred onto SiO2/Si via PMMA and thermal release tape for transport measurements. The resulting centimeter-sized graphene samples were measured at temperatures down to 30mK in a magnetic field. We observe a very sharp peak in resistance at zero field, which is well fitted by weak localization theory. The samples exhibit conductance fluctuations symmetric in field, which are attributed to ensemble averaged conductance fluctuations due to large scale inhomogeneities consistent with the grain boundaries of copper during the CVD growth.
Anisotropic etching of single crystalline SiC using molten KOH for SiC bulk micromachining

Microelectromechanical systems (MEMS) devices made of single crystalline silicon carbide (SiC) are attractive for applications in harsh environment, because SiC is chemically inert and semiconductor devices made of SiC can be operated at very high temperature. On the other hand, due to its chemical inertness, controllable etching of SiC has been difficult. Molten KOH etching has been widely used to detect crystalline defects in SiC as etch pit in crystal growth researchers. Some etch pits have hexagonal shape, indicating anisotropic etching nature. Therefore, molten KOH etching may have potential as a SiC MEMS fabrication process. In this study we have developed the anisotropic wet chemical etching of single crystalline hexagonal SiC using molten KOH for SiC bulk micromachining. 6H-SiC (0001)Si face and (000-1)C face substrates are used. Etching rates of (0001)Si and (000-1)C faces at 490 °C are evaluated to be 37 nm/min and 3.1 μm/min, respectively, indicating that the (0001)Si face is etched almost 100 times slower than the (000-1)C face is. Cross sectional analysis of etched structure of (000-1)C face revealed that inclined crystal plane was formed as a sidewall with some undercut. To assess in-plane etching anisotropy, ring shape mesa structures are formed on SiC (0001)Si face by RIE and then etched by molten KOH. Ring shape changed into hexagonal shape, clearly indicating etching rate along <11-20> direction is larger than <1-100> direction in (0001)Si face.

Variabilidade espacial da umidade do solo em irrigação por gotejamento sob cultivo protegido

Foi estudada a variabilidade espacial da umidade do solo num sistema de irrigacao por gotejamento em uma estufa (5,0 x 20,0m) na Fazenda Experimental Sao Manuel, da Faculdade de Ciencias Agronomicas, Universidade Estadual Paulista, Estado de Sao Paulo, Brasil. Foi estabelecida a malha de amostragem no espacamento de 1,0 x 0,5m, acrescida de quatro adensamentos de 0,25m. Foram utilizados dados da umidade do solo em 178 pontos. A analise da dependencia espacial foi obtida com o auxilio do Programa GS+. Foi construido o variograma experimental e definido o modelo de ajuste, de modo que a curva que melhor se ajustou aos pontos obtidos representasse a magnitude, alcance e intensidade da variabilidade espacial da variavel estudada. A umidade do solo apresentou distribuicao espacial anisotropica. Para a direcao 0 ° , pode-se notar uma dependencia espacial caracterizada como alta, com o alcance de aproximadamente 3,30m, no sentido do comprimento da estufa. Entretanto, no sentido da largura da estufa, nao foi possivel ajustar modelos. Utilizando a representacao grafica da superficie, a area estudada apresentou um maior teor de agua na parte inicial e menor na parte final das linhas de distribuicao de agua. A krigagem mostrou-se um bom interpolador para mapeamento da umidade do solo. UNITERMOS: geoestatistica, dependencia espacial, umidade do solo, irrigacao por gotejamento, cultivo protegido.

SPATIAL VARIABILITY OF SOIL MOISTURE IN A DRIP IRRIGATION SYSTEM UNDER GREENHOUSE 2 ABSTRACT Soil moisture spatial variability in a drip irrigation system was studied in a greenhouse (5.0 x 20.0m) at Sao Manuel Experimental Farm, FCA/UNESP, Botucatu – SP, Brazil. Sampling was established in a 1.0 x 0.5m grid, increased 0.25m thickening. Soil moisture data were used in 178 points. The spatial dependence analysis was obtained with the aid of the GS+ Program. The experimental variogram was built and the setting model defined, so that the curve better fitted to the obtained points represented the spatial variability magnitude, range and intensity of the studied variable. Soil moisture presented anisotropic spatial distribution. Spatial dependence was noticed for 0° direction, characterized as high, with approximately 3.30m range in the greenhouse length ward. However, in the greenhouse width ward, it was not possible to fit models. Using the surface graphic representation, the studied area presented higher water content in the initial part and a lower one in the final part of water distribution lines. Kriging was shown to be a good interpolator for soil moisture mapping. KEYWORDS: geostatistics, spatial dependence, soil moisture, drip irrigation, greenhouse.
Effet de la perception de justice organisationnelle des travailleurs au Niger sur leur satisfaction au travail

Resume Cette etude explore le lien entre la perception de justice distributive, procedurale, interactionnelle et la satisfaction des travailleurs au Niger. Pour atteindre ce but, un questionnaire a ete administre a un echantillon de 125 travailleurs de la ville de Niamey du secteur public, associatif et prive. Les resultats obtenus mettent en evidence un lien correlationnel positif et significatif entre la satisfaction des travailleurs et les differentes dimensions de la justice organisationnelle. Par ailleurs, un effet de la justice interactionnelle sur la satisfaction des travailleurs ainsi que des effets tendanciels de la justice procedurale et de la justice distributive sur la satisfaction des agents permettent de considerer, avec la litterature sur la question, que les resultats de la presente etude contribuent a l’explication que la satisfaction des travailleurs peut dependre de l’appreciation positive qu’ils auront de la justice organisationnelle.
Conformal Fields in Higher Dimensions

We generalize, to any space-time dimension, the unitarity bounds of highest weight UIR's of the conformal groups with Lie algebras $so(2,d)$. We classify gauge theories invariant under $so(2,d)$, both integral and half-integral spins. A similar analysis is carried out for the algebras $so^*(2n)$. We study new unitary modules of the conformal algebra in $d>4$, that have no analogue for $d\leq 4$ as they cannot be obtained by "squaring" singletons. This may suggest the interpretation of higher dimensional non-trivial conformal field theories as theories of "tensionless" $p$-branes of which tensionless strings in $d=6$ are just particular examples.
Exergames como forma de cuidado no âmbito da Saúde Mental: estado da arte e perspectivas futuras

Este estudo apresenta o estado da arte das pesquisas com exergames na saude mental, tendo como objetivo mapear a producao academica acerca da utilizacao dos exergames como forma de cuidado no âmbito da saude mental. Foram realizadas buscas por trabalhos nas bases de dados Periodicos CAPES, PubMed, Web of Science, SciELO e Biblioteca Virtual em Saude (BVS). As buscas foram realizadas nos meses de abril e maio de 2019 e foram limitadas em trabalhos empiricos publicados em periodicos revisados por pares entre os anos de 2005 e 2019. Ao total, foram encontrados 292 trabalhos, mas, apos a remocao de artigos duplicados (n=53), apos a leitura do titulo e resumo do artigo (n=227) e leitura na integra dos artigos (n=6), identificamos que apenas 6 (seis) deles abordavam a utilizacao dos exergames como forma de cuidado na saude mental. A partir dos resultados dos estudos, em sintese podemos constatar que os exergames podem ser utilizados como uma alternativa potencial para o cuidado em saude mental, tendo em vista que o fator motivacional ocasiona maior adesao a programas de exercicio fisico baseados em jogos digitais, trazendo beneficios tanto cognitivo/psicologicos quanto fisico/fisiologicos.
