Physical Self-Perception and Sport's Activity Applied in Physical Education Context: The Self-Efficacy of Achievement Performance

ABSTRACT This study case has a double purpose. It aims 1) to examine students’ physical self-perception (PSP) in physical education (PE) with construction and validation of (PSP) Questionnaires; 2) to analyse the relationships between students’ self-perception, physical condition, body fat, appearance, self-esteem , all to predict student ‘physical’ self-efficacy in and outside secondary school. Participants consist of 179 secondary-school students 15 to 19 years old (109 girls; 70 boys). The first study was designed to develop and validate (PSP) Questionnaires among pupils. Factor analyses were conducted to determine the underlying structure of the (PSP). The confirmatory factor analyses were used to assess reliability and validity of the Questionnaires. In a second study, correlation designs were used to evaluate relationships between (PSP) and performance in for physical education activities (gymnastics, shot put, basket-ball and long jump). Then, a deductive study, testing a model of predictors ‘physical’ self efficacy with regression analyses, was undertaken. Exploratory and confirmatory factor analyses suggested that the final items version of the PSP questionnaire is represented by eight variables, respectively. These have been labeled: (appearance, body fat, strength, endurance, coordination, flexibility, self esteem and health). The (PSP) items display satisfactory internal consistency values with α = . 76 and α =. 73), respectively. ‘Physical’ self efficacy was predictable from performance (β = .508, p < .001), physical condition (β = .181, p < .001), self esteem (β = .91, p < .05), and health (β = .188, p < .01). Some sub-scales of (PSP) can be predictors for ‘physical’ self efficacy. A good correlation between physical self-perception (PSP) and the self-efficacy was highlighted. Thus the (PSP) Questionnaire provides a useful method to study the relationships between the physical self-perception and physical education average performance in order to predict the ‘physical’ self-efficacy. Estimating that this method may have implications for prescription of ‘physical’ self-efficacy and promoting the physical well-being, it can be extended to other populations in order to be confirmed and to have a more general value. Keywords: Physical self-perception, Self-esteem, Performance, Self-Eefficacy.
Disability and equity in global health

Persons with disabilities are among the poorest and most disadvantaged in any population, with the worst health and poverty outcomes, and the lowest access to health and social services (1). Defining equity as ‘the absence of avoidable or remediable differences among groups of people’ (2), implies that equity in health cannot be achieved without addressing the needs of persons with disabilities (3, 4). It is therefore necessary to act on the challenges persons with disabilities face in accessing health care, particularly in poor societies, as an essential part of addressing equity in the global health agenda. This article discusses the interaction between disability, poverty and equity in health, and a new agenda for practice and research.
Ngā Tuakiri o te Tangata: Being Māori in Early Childhood Education

Before the arrival of Europeans in Aotearoa, New Zealand and their subsequent settlement in the 1800s, there was no concept of a Māori identity. Over time, however, as a result of rapid colonisation, Māori became a minority population in New Zealand. Consequently, the term Māori as normal or usual, began to lose its meaning (Webber, 2008), and another meaning began to emerge based on contrasts with the Pākehā settler population. This paper explores the complex and increasingly diverse nature of Māori identities in contemporary Aotearoa/New Zealand, including contemporary early childhood contexts. It discusses the importance of negotiating the terrains of cultural knowledge, values and understandings in order to define what ‘being Māori’ means for teachers and children in an increasingly diverse and complex settings.
Photocatalytic degradation of dyes in water by analytical reagent grades ZnO, TiO 2 and SnO 2 : a comparative study

Abstract. In this study, we evaluated the photocatalytic activities of analytical reagent (AR) grade ZnO, TiO2, and SnO2 to identify a low-cost photocatalyst for dye degradation. The obtained samples of ZnO, TiO2, and SnO2 were characterised by X-ray diffractogram (XRD), scanning electron microscope imaging, and UV-VIS diffuse reflectance spectroscopy. The decolourisation of three structurally diverse dyes, namely crystal violet, basic blue, and methyl red under solar irradiation, was used to evaluate the photocatalytic activities of three metal oxides. The photocatalytic activities of the received three metal oxides were tested with the photocatalytic degradation of dyes and compared with Degussa P-25. Dye solutions with each metal oxide at initial pH 9 were subjected to irradiation under sunlight and monitored for up to the stage of complete decolourisation. The results indicate that ZnO exhibited the highest photocatalytic activity as compared to TiO2 and SnO2 as well as that of Degussa P-25 (TiO2). The photocatalytic dye decolourisation rates with ZnO were 1.14–1.35, 1.70–3.1, and 4–8.5 times higher than those of the Degussa P-25, TiO2, and SnO2, respectively. The percentage COD removal was studied for ZnO and partial removal was observed at the decolourisation stage. To enhance photocatalytic activity of AR grade ZnO, it was loaded with Ag metal and about 20 % enhancement in the activity was observed.
Phenomenology of buoyancy-driven turbulence: recent results

In this paper, we describe the recent developments in the field of buoyancy-driven turbulence with a focus on energy spectrum and flux. Scaling and numerical arguments show that the stably-stratified turbulence with moderate stratification has kinetic energy spectrum E u ( k ) ∼ k − 11 / 5 and the kinetic energy flux Π u ( k ) ∼ k − 4 / 5 , which is called Bolgiano-Obukhov scaling. However, for Prandtl number near unity, the energy flux for the three-dimensional Rayleigh–Bénard convection (RBC) is approximately constant in the inertial range that results in Kolmorogorv’s spectrum ( E u ( k ) ∼ k − 5 / 3 ) for the kinetic energy. The phenomenology of RBC should apply to other flows where the buoyancy feeds the kinetic energy, e.g. bubbly turbulence and fully-developed Rayleigh Taylor instability. This paper also covers several models that predict the Reynolds and Nusselt numbers of RBC. Recent works show that the viscous dissipation rate of RBC scales as ∼ Ra 1.3 , where Ra is the Rayleigh number.
Intercropping Cedrela odorata with Shrubby Crop Species to Reduce Infestation with Hypsipyla grandella and Improve the Quality of Timber

Cultivation of Cedrela odorata, a valuable tropical hardwood species, is restricted by the mahogany shoot borer (Hypsipyla grandella), whose attacks reduce stem quality in forest plantations. This study investigated whether infestation rates would be reduced and growth performance improved by the intercropping of C. odorata tree seedlings with different crop rotations. The height increment achieved by C. odorata during the first two years was significantly stimulated by the intercropping of maize (Zea mays), pigeon pea (Cajanus cajan), and cassava (Manihot esculenta). Attacks of H. grandella were also considerably reduced in these treatments, compared to the control plots, while intercropping with beans and rice produced no improvement. The effect was particularly distinct when lateral competition between trees and crops was high. Accordingly stem quality was higher in the treatments featuring tall crops. Trees intercropped with C. cajan performed best in terms of height (276 cm ), survival (100% ±0), and quality (81% ±13.5 of trees with satisfying stem quality) after two years. We concluded that intercropping of tree seedlings which are susceptible to H. grandella with shrubby multipurpose species can improve both tree growth and timber quality and hence increase the attractiveness of such species for reforestation.
Search for the shortest variability at gamma rays in flat-spectrum radio quasars

We report about the search for short-term variability in the high-energy gamma-ray energy band of three flat-spectrum radio quasars (3C 454.3, 3C 273, PKS B1222+216), whose flux at E > 100 MeV exceeded the value of 10^-5 ph cm^-2 s^-1 for at least one day. Although, the statistics was not yet sufficient to effectively measure the characteristic time scale, it allowed us to set tight upper limits on the observed doubling time scale (< 2-3 hours) -- the smallest measured to date at MeV energies --, which can constrain the size of the gamma-ray emitting region. The results obtained in the present work favor the hypothesis that gamma rays are generated inside the broad-line region.
Effects of Synbiotics Containing Anaerobic Microbes and Prebiotics on In vitro Fermentation Characteristics and In situ Disappearance Rate of Fermented-TMR

This study was carried out to estimate effects of synbiotics containing anaerobic microorganisms and prebiotics on in vitro fermentation characteristics and in situ disappearance rate of fermented total mixed ration (F-TMR). For the in vitro trial, ninety vinyl bags were prepared to analyze temperature, pH, ammonia concentration, microbial growth rate and short chain fatty acid concentration. For the in situ trial, one hundred twenty nylon bags were prepared to analyze dry matter (DM), acid detergent fiber (ADF) and neutral detergent fiber (NDF) disappearance rate. Treatments consisted of a basal diet (US) with prebiotics and probiotics from anaerobic mold (MS), bacteria (BS), yeast (YS) or compound (CS). It was found that temperatures at 14 and 21 days were significantly higher (p<0.05) in the YS and CS than in the others. The pH at 21 days was lower in the CS than in the US. The synbiotic treatments had significantly increased (p<0.05) ammonia concentration at 21 days. The DM disappearance at 72 h was significantly higher (p<0.05) in the MS and CS than in the others. ADF and NDF disappearance rate tended to increase at a rate similar to the DM disappearance rate. Therefore, this study suggests that synbiotics (probiotics with prebiotics) may partially help the quality of fermentation and digestibility
Preconditioning treatment maintains taste characteristic perception of ripe ‘September Sun’ peach following cold storage

Summary Preconditioning is a thermal treatment that consists in maintaining stone fruits immediately after harvest and prior to cold storage at 20 °C for 24–48 h in special chambers aimed to extend fruit market life reducing chilling injury symptoms. This work investigates whether preconditioned ‘September Sun’ peaches had better eating quality than control fruit. Commercially harvested peaches were preconditioned and transferred to cold storage for 12, 26 and 40 days and evaluated for sensory characteristic perception after a ripening period at 20 °C. Acceptability of preconditioned fruit was higher than control fruit during this 40-day cold-storage period. Preconditioned and control fruit were also segregated into two clusters by PCA analysis; preconditioned fruit clustered together and show association to acceptability, sweetness and juiciness, while the second cluster was associated with flesh texture, acidity and aroma, suggesting the positive effect of preconditioning on final fruit quality. Preconditioned fruit maintained their sensory characteristics longer than control fruit during this 40-day cold-storage period.
On dynamics of quasi-graph maps

In this paper, we study dynamics of maps on quasi-graphs characterizing their invariant measures. In particular, we prove that every invariant measure of quasi-graph map with zero topological entropy has discrete spectrum. We also obtain an analog of Llibre-Misiurewicz's result relating positive topological entropy with existence of topological horseshoes. By these results, Sarnak's Mobius Disjointness Conjecture restricted to the class of quasi-graph maps with zero topological entropy is reduced to already known cases. We prove however, that answering the conjecture for all maps on dendrites with zero topological entropy is equivalent to solving it for all dynamical systems with zero topological entropy.
Performance evaluation of cocoa marketing in Osun State, Nigeria

This paper appraised cocoa marketing performance in Osun State, Nigeria. The study specifically examined the costs and returns associated with cocoa marketing, and determined factors affecting cocoa marketing performance in the area. Primary data were used and collected through a well structured questionnaire and focus group discussion session. A multistage sampling procedure was employed to randomly select 120 respondents for the study. The analytical tools used were: descriptive statistics, budgetary analysis and Seeming Unrelated Regression Equation (SURE). The results of costs and returns using budgetary analysis showed that cocoa marketing is a profitable enterprise with a Return on Investment (ROI) of 1.36 which implies that cocoa marketer will realize 36Kobo on each naira expended. Again, percentage profit of over 35% further confirmed that cocoa marketing is a highly profitable venture in the study area. The SURE results showed that age of the cocoa marketers, marital status, household size, years of education, years of marketing experience, marketer institution group, depreciation cost on fixed inputs, number of stores, cost of labour, cost of transportation, season of sales, cocoa bean quality and incidence of theft were statistically significant factors affecting performance of cocoa marketing in the study area.
Smallholder Agro-pastoralists Commercialization of Major Crop (Maize and Onion) in Fentalle District: The Case of Boset-Fentalle Irrigation Scheme, Ethiopia

The study was conducted in Fentalle agro-pastoral district with the aim of studying the level of small holder agro-pastoral crop commercialization and analyzing the determinants of commercialization among the smallholder agro-pastoralists in the study area. Multi stage and random sampling technique was used to draw 109 households from three Kebele in the district. Data was collected with structured interview and analyzed using descriptive and Tobit regression. In addition, household commercialization index was calculated. The findings revealed that half of the respondents were not commercialize their product. Distance to the district market and TLU negatively affect commercialization and market participation meanwhile, the use of input and household income enhanced surplus production and commercialization. The study forwarded that improved market facility and market information access is necessary. The optimal and economical use of input will intensify crop production along with economical return.
EFFECT OF N-TRIACONTANOL ON THE GROWTH OF SALT STRESSED SOYBEAN PLANTS

The present investigation was made to describe the effect of foliar application of n-triacontanol on plant growth, physiological and biochemical parameters in soybean under sodium chloride (NaCl) stress. The seeds were propagated into the soil supplemented with 10, 15, 20, 25 and 30 mM NaCl. A moderate reduction of plant growth was observed in 20 mM NaCl treatment compared to other concentration of NaCl treatments. Hence, the n-triacontanol was sprayed on the plants grown under the 20 mM NaCl added soil. Increased in specific leaf area (SLA), leaf weight ratio, relative water content and decreased in leaf osmotic potential were noted in n-triacontanol treated plants than that of salt stressed untreated plants. Moreover, the chlorophyll pigments, nucleic acids, total soluble sugars and proteins were also found to be increased in the n- triacontanol treated plants. The accumulation of proline was decreased in salt stressed plants that had been treated with n-triacontanol. The present study effectively proved that n-triacontanol was able to restore the normal metabolic process in the salt stressed soybean.
Testing a model of the antecedents and consequences of budgetary participation on job performance

Abstract This paper examines the effect of antecedents (such as task exceptions and task analysability) and consequences (such as job-relevant information, budget goal level, budget goal acceptance and budget goal commitment) of budgetary participation on job performance. The responses of 135 middle-level managers, drawn from a cross- section of manufacturing firms, to a survey questionnaire, were analysed by using a structural equation modelling (SEM) technique. The results of this study suggest that task exceptions and task analysability are important antecedents of budgetary participation. The results further suggest that the cognitive effect of participation in goal- setting allows subordinates to gather, exchange and share job-relevant information. The availability of job-relevant information allows subordinates to develop effective strategies or plans, which will help them to exert effort over time, in an attempt to attain their goals. The results support the proposition that setting difficult but attainable budget goals increases subordinates? budget goal level, acceptance, and commitment to the budget goal, which in turn improves job performance.
Irregular variables of type Lb. New JHKL'M-photometry for 160 stars

This paper presents new near infrared observations of 160 Irregular variables of type Lb in the JHKL 0 M lter bands. These measurements are supplemented by data for additional 56 stars taken from the literature. In total 220 datasets are available because of some multiple observations. From our sample, 216 stars have near infrared (NIR) photometry now. Our sample of visually bright Lb-variables displays very similar infrared properties when compared with SRa- and SRb-variables. Derived from NIR-two colour diagrams the oxygen-rich Lbs seem to have intermediate atmospheric conditions between Miras and normal giants. There may be a sligthly larger \contamination" with non AGB-giants than in the case of the semiregulars. Using only our IR-colours the S- and the Carbon-stars among the Lbs again are undistinguishable from SR-variables of the same chemistry.
State-selective intersystem crossing in nitrogen-vacancy centers

Motivated by recent measurements of state-selective intersystem crossing (ISC) in the nitrogen-vacancy (NV) center in diamond (see companion PRL), a new microscopic model is developed of the key ISC mechanism. These nonradiative transitions between states of different spin multiplicity are pivotal in the optical initialization and readout of the NV center's electronic spin, which has created a diverse range of room-temperature applications in metrology and quantum information science.
Situational effects of the school factors included in the dynamic model of educational effectiveness

We present results of a longitudinal study in which 50 schools, 113 classes and 2,542 Cypriot primary students participated. We tested the validity of the dynamic model of educational effectiveness and especially its assumption that the impact of school factors depends on the current situation of the school and on the type of problems/difficulties the school is facing. Reference is made to the methods used to test this assumption of the dynamic model by measuring school effectiveness in mathematics, Greek language, and religious education over two consecutive school years. The main findings are as follows. School factors were found to have situational effects. Specifically, the development of a school policy for teaching and the school evaluation of policy for teaching were found to have stronger effects in schools where the quality of teaching at classroom level was low. Moreover, time stability in the effectiveness status of schools was identified and thereby changes in the functioning of schools were found not to have a significant impact on changes in the effectiveness status of schools. Implications of the findings for the development of the dynamic model and suggestions for further research are presented.
Changes in severe thunderstorm environment frequency during the 21st century caused by anthropogenically enhanced global radiative forcing

Severe thunderstorms comprise an extreme class of deep convective clouds and produce high-impact weather such as destructive surface winds, hail, and tornadoes. This study addresses the question of how severe thunderstorm frequency in the United States might change because of enhanced global radiative forcing associated with elevated greenhouse gas concentrations. We use global climate models and a high-resolution regional climate model to examine the larger-scale (or “environmental”) meteorological conditions that foster severe thunderstorm formation. Across this model suite, we find a net increase during the late 21st century in the number of days in which these severe thunderstorm environmental conditions (NDSEV) occur. Attributed primarily to increases in atmospheric water vapor within the planetary boundary layer, the largest increases in NDSEV are shown during the summer season, in proximity to the Gulf of Mexico and Atlantic coastal regions. For example, this analysis suggests a future increase in NDSEV of 100% or more in locations such as Atlanta, GA, and New York, NY. Any direct application of these results to the frequency of actual storms also must consider the storm initiation.
The Optimal Tariff in the Presence of Trade-Induced Productivity Gains

We scrutinize the impact of international productivity gains (spillovers) induced by imports and exports on optimal tariffs. Our research question reads: how do trade-induced international productivity gains influence the choice of the optimal tariff? Trade-induced international technology spillovers (productivity gains) are implemented in a Computable General Equilibrium (CGE) model in GAMS that uses the novel global WIOD data set. The CGE implementation is backed up by a stylized theoretical model, and the strength of productivity spillovers is econometrically estimated by using the WIOD data. First, we show theoretically that (a) productivity gains via exports and imports both reduce the strategically optimal tariff, (b) there exists a certain strength of productivity gains such that the incentive to manipulate the terms of trade strategically vanishes, (c) the welfare gain that can be achieved via a tariff is lower in the presence of productivity gains than in their absence, and (d) these results even hold without power on international markets. Second, we estimate econometrically that import-driven productivity gains are stronger than export-driven productivity gains. Third, we find numerically that optimal tariffs are reduced by 1% for the USA and China and 40% for Brazil when taking trade-induced productivity gains into account. The USA are the only model region that gains from European optimal tariff policy. Overall, we show that trade-induced productivity gains have empirically relevant effects on optimal tariffs.
Urban Structure and Housing Prices: Some Evidence from Australian Cities

This paper studies determinants of some aspects of the structure of cities, including density and the price of land and housing. We use a version of the Alonso-Muth-Mills model, calibrated to broadly match some of the features of a representative large city. While the calibrated model omits many real-world features, it can nonetheless be used to explore the impact of factors such as: (i) the provision of transport infrastructure; (ii) zoning policies that limit housing density; (iii) frictions on the production of housing; and (iv) population size. The empirical section of the paper shows that the model is consistent with some empirical regularities for large Australian cities. The results of the paper draw attention to structural factors that may have contributed to developments in the Australian housing market in recent years.
