Acute Effect of A Judo Contest on Muscular Performance Parameters And Physiological Response

Background: It is necessary to know accurately the physical effects of judo contest on athletes in order to quantify how successive judo bouts impair muscular performance parameters and physiological response associated with the aim to create specific training programs that take the demands of judo bout into account. Purpose : The purpose of current study was to characterise the evolution of muscular performance parameters and physiological response during a judo contest. Methods : Twenty-nine men performed five 5-minute bouts with 15 minutes of passive rest. Immediately after the bouts, some muscular performance parameters and physiological variables were measured, in this order: Borg´s rate of perceived exertion (RPE), maximal dynamic strength in upper body (MDS), countermovement jump (CMJ), dominant (DHS) and non-dominant handgrip isometric strength (NDHS). Lactate (LAC) was measured 3 minutes after each bout and 1 minute before the next too). Heart rate (HR) was monitored during the contest. ANOVA to compare baseline test data and successive bouts was used. Results : ANOVA revealed significant differences in HR mean (p=0.045), LAC (p<0.001) and in RPE (p<0.001). A decrease in NDHS (p<0.001), DHS (p<0.001), MDS (p<0.001) was found. Some significant correlations were found between NDHS and DMPV (r=0.368, p=0.050), DMS (r=0.369, p=0.050) and DMXS (r=0.405, p=0.029); between DHS and DLACb (r=0.430, p=0.020), DMXS (r=0.379, p=0.043), DMP (r=0.369, p=0.050) and DRPE (r=0.456, p=0.013); between CMJ and DPM (r=0.381, p=0.041), DPMX (r=0.417, p=0.024), DFM (r=0.423, p=0.022) and DDHS (r=0.348, p=0.040). These results show a high decrease of muscular performance parameters and an increase of physiological parameters, specially between baseline test and postbout 5, but gradual between all bouts. Conclusion : Judo contest can be considered a high intensity exercise, due to high levels of physiological parameters and the decrease in force production obtained.

Power system frequency deviation measurement using an electronic bridge

A very simple frequency-deviation measuring instrument that works on the principle of a two-arm bridge is described. The circuit was fabricated and tested in the laboratory. The results indicate good linearity between frequency deviation and voltage or pulse count over the normal range of power system frequencies. The same instrument along with a variable frequency supply can also be used to measure a capacitance or a resistance. >
LINKING ADMINISTRATORS ROLES IN CAREER PROGRAMS TO PROACTIVE BEHAVIOR AS A DETERMINANT OF EMPLOYEES PROMOTION OPPORTUNITIES

This research examines the relationship between administrators roles in career programs, proactive behavior and employees promotion opportunities. Self-administered questionnaires were collected from employees who work in an established private oil and gas firm in West Coast of Peninsular Malaysia. The outcomes of SmartPLS path model analysis demonstrate that the ability of administrators to plan and managecareer programs have strongly invoked employees proactive behavior. As a result, this situation may lead to an enhance employees promotion opportunities in the organizational sample. Further, this study offers discussion, implications and conclusion.
Obtaining the Maximum Likelihood Estimates in Incomplete R C Contingency Tables Using a Poisson Generalized Linear Model

Abstract This article describes estimation of the cell probabilities in an R × C contingency table with ignorable missing data. Popular methods for maximizing the incomplete data likelihood are the EM-algorithm and the Newton-Raphson algorithm. Both of these methods require some modification of existing statistical software to get the MLEs of the cell probabilities as well as the variance estimates. We make the connection between the multinomial and Poisson likelihoods to show that the MLEs can be obtained in any generalized linear models program without additional programming or iteration loops.
On the optimality of PAYG pension systems in an endogenous fertility setting

In order to help in designing an accurate pension reform, we determine the resource allocation in an endogenous fertility model that generates an endogenous demographic transition by means of distinguishing between female and male labor. We analyze the problem of the optimal solution and characterize the decentralization of the first best. We show that a pension policy linking pension benefits to the number of children acts as a corrective tax system able to restore both the optimal capital stock and the optimal rate of population growth as a single instrument. We also show that neither a Beveridgean pension scheme nor a Bismarckian one can decentralize the first best.
QTL Analysis in Aromatic Rice of Assam, India

The study was carried out to identify quantitative trait loci (QTLs) controlling 12 morphological traits in rice using a F2 derived from Ranjit and Kola Joha cross. A framework linkage map of 1387.9cM was developed using 102 SSR markers and other few markers linked to aroma. QTL analysis based on composite interval mapping identified 24 QTLs was for 12 traits. Among them two QTLs were identified for grain aroma each on chromosome 5 and chromosome 8, out of which the QTLs between Aro1-BAD2 is in similar position with aroma gene of Basmati rice. Most of the QTLs identified in the current study, showed a range of partial to over-dominance effects, indicating complexity of the traits under consideration. Some genomic regions were associated with more than one trait, indicating linkage and/or pleiotropic effects. Marker linked to the QTLs can be considered for use in marker assisted breeding as being confirmatory to other reports.
Prediction of Heave of Expansive Clay Reinforced with Granular Pile

Expansive soils are considered to be one of the most problematic soils. Structures, especially the lightly-loaded ones, founded in these soils, experience distress and develop cracks due to the alternate swelling and shrinkage of the soil. In the dry state, the bearing capacity of the soil will be high but in the swollen state, it decreases quite appreciably. Granular piles, anchored at the bottom to a steel plate, through a steel rod fastened to the surface footing, are called granular pile-anchors. Their efficacy in reducing heave, when used to reinforce expansive soil beds, was already established through laboratory and field studies. From the results of the laboratory investigations, multiple linear regression analysis has been performed in this paper, using the various independent variables, for determing the swelling potential of the reinforced soil. The validity of the above correlation has been checked by conducting experiments with variables other than those used in the laboratory investigations. Using the correlation, the swelling potential of the expansive soil, reinforced with granular pile-anchors, can be predicted.

Teamwork Online: The Effects of Computer Conferencing on Perceived Confusion, Satisfaction, and Postdiscussion Accuracy

This study investigated the impact of computer-mediated communication on teamwork by examining 40 4-person teams working in either face-to-face or computer conferencing environments. Results were consistent with the belief that computer-mediated teams have trouble maintaining mutual knowledge. Compared with their face-to-face counterparts, computer-mediated teams viewed their discussions as more confusing and less satisfying, spent more time devising decisions, and felt less content with their outcomes. Discussion time mediated the relationship between the communication medium and outcome satisfaction. Confusion and outcome dissatisfaction predicted inaccuracies when members independently recorded team decisions; accordingly, the electronic communication medium reduced decision recording accuracy. By clarifying several shortcomings associated with computer conferencing, these results can be used to inform choices when selecting and developing effective team communication media.
A Comparative Perspective on Poverty Reduction in Brazil, China and India

Brazil, China and India have seen falling poverty in their reform periods, but to varying degrees and for different reasons. History left China with favorable initial conditions for rapid poverty reduction through market-led economic growth; at the outset of the reform process there were ample distortions to remove and relatively low inequality in access to the opportunities so created, though inequality has risen markedly since. By concentrating such opportunities in the hands of the better off, prior inequalities in various dimensions handicapped poverty reduction in both Brazil and India. Brazil's recent success in complementing market-oriented reforms with progressive social policies has helped it achieve more rapid poverty reduction than India, although Brazil has been less successful in terms of economic growth. In the wake of its steep rise in inequality, China might learn from Brazil's success with such policies. India needs to do more to assure that poor people are able to participate in both the country's growth process and its social policies; here there are lessons from both China and Brazil. All three countries have learned how important macroeconomic stability is to poverty reduction.
Pre-emptive policy for systemic banking crisis

Systemic banking crises often result from widespread imprudent lending, driven by strong incentives for risk taking and connected lending. This paper identifies a counterbalancing incentive for in-dividual banks to act prudently in the face of widespread risk taking among its competitors. In general, the value of a banking charter is enhanced by reduced competition. Hence a deliberate policy of pro-moting takeovers of weaker institutions by solvent banks has the effect of increasing the charter value of solvent banks, and grants the managers of better banks an incentive to pursue less profitable but safer lending strategies, thus breaking down the strategic externality of risk-taking strategies. A temporary phase of concentration in banking can thus reinforce stability and pre-emptive closures may in fact reduce the risk of a systemic banking crisis. We also address the case where banking authorities face pressure for an ex post bailout in a context where many banks are in trouble at the same time.
Assessing the impact of spear fishing by using competitions records and underwater visual censuses

Recreational fishers are increasingly competing for space and resources with commercial fishers worldwide, but have been poorly studied. In particular, the impacts of spearfishing competitions on the temperate fish assemblages have seldom been analysed. In Galicia (NW Spain), there are currently 5000 spear fishers, and 500 of them participate in spearfishing competitions. An historic archive of spearfishing competitions was used to assess their influence on the subsequent competitions in the area and to analyse their effect on the fish abundances estimated by underwater visual censuses. The annual recreational catch of the spear fishers was also estimated and comparisons with the commercial landings were performed. The spear fishers targeted 29 species, although six accounted for 95% of the catch. Most of the species show low vulnerabilities to fishing pressure and only Dicentrarchus labrax, among frequently caught species, can be considered as moderately vulnerable. The overall impact of spearfishing competitions on fish populations was limited, although some competitions temporarily reduced the abundances of Labrus bergylta , the main target species, by up to 83%. Spear fishers caught a large proportion of the total catch of common species, with recreational catches of some species (e.g. L. bergylta ) matching or exceeding the commercial catch. The inclusion of this fishery in the management models of the coastal ecosystems is strongly recommended.
Screen-based behaviour in Czech adolescents is more prevalent at weekends

Background: One of the main reasons for recent scientific interest in screen-based behaviour (SB) is the relationship between SB and risk of being overweight or obese. The primary mechanism for overweight and obesity is an imbalance of energy intake versus energy expenditure and one reason for the interest in SB is its association with reduced energy expenditure relative to other activities. Objective: The aim of this study is to provide a basic overview of the level and structure of SB in Czech adolescents on the basis of age and gender while taking into account the differences between weekday and weekend screen based activities. Methods: Data from the Health Behaviour in School-aged Children (HBSC) study conducted in May-June 2010 in the Czech Republic were used. The sample consisted of 4365 Czech pupils (48.5% boys; age 11, n = 1406; age 13, n = 1446; age 15, n = 1513). Binomial logistic regression and Chi-square test of independence were used to provide basic comparison on the basis of gender and age groups. Results: The prevalence of SB rise with growing age with the most visible increase in prevalence is between ages 11 and age 13. SB is significantly more prevalent among adolescent boys compared with adolescent girls. Czech adolescents are more likely to not meet the recommendation of 2 hours for watching TV at weekends compared to weekdays. Playing computer games is more common among boys contrary to chatting online, which is more common among girls. The overall patterns of playing computer games and chatting online during weekends were similar to those at weekdays but increased. Conclusions: Most children in the Czech Republic do not meet the limit for total SB time of 4 or fewer hours while the prevalence of SB rises with growing age and at weekends. Interventions and strategies aiming at reducing SB in children focusing on the family and school environment in the Czech Republic are required.
Correct normalization of the Dst index

The Dst index has been one of the most important solar-terrestrial indices for decades, and it is used in numer- ous studies as a measure of the temporal development and intensity of magnetic storms and the ring current. Here we discuss two issues related to the relative and absolute normal- ization that are problematic to the Dst index. We show for the first time quantitatively that the magnetic disturbances at the four Dst stations are ordered according to the latitudinal pro- jection of an equatorial disturbance upon the local horizontal component of the geomagnetic field. Therefore, the distur- bances observed at each station should be first normalized by the cosine of the geomagnetic latitude of the station before they are averaged to form the Dst index. Perhaps surpris- ingly, the recipe to calculate the Dst index does not include this normalization and, therefore, must be revised on this part. We also discuss the effects of correcting the quiet-time seasonal variation, the so called "non-storm component" in the Dst index. This correction is seasonally varying, being largest around equinoxes and smallest at solstices, leading to an average correction (increase) of about 6 nT, i.e. about 25-30%, for annual averages of the Dst index. This increase also leads to significantly improved correlations between the corrected Dst index, the so called Dcx index, and many other indices of solar-terrestrial disturbance. We show here in de- tail that the correlation between the geomagnetic Ap index and the Dcx index (cc = 0.83) is much higher than between Ap and Dst (cc = 0.60). These results give further evidence that the Dcx index is a more truthful measure of magnetic storminess than the original Dst index.
Thermal Metamorphism in Chondrites

Thermal metamorphism has affected most chondritic meteorites to some extent, and in most ordinary chondrites, some carbonaceous chondrites, and many enstatite chondrites it has significantly modified the primary characteristics of the meteorites. Metamorphic grade, as described by the petrologic type, is one axis of the current two-dimensional system for classifying chondrites. Many changes are produced during thermal metamorphism, including textural integration and recrystallization, mineral equilibration, destruction of primary minerals, and growth of secondary minerals. Understanding these changes is critical if one hopes to infer the conditions under which chondrites originally formed. In addition to summarizing metamorphic changes, we also discuss temperatures, oxidation states, and possible heat sources for metamorphism.
Electrical properties of Nb–MoSi2–Nb Josephson junctions

We present a detailed study of the electrical properties of planar Nb–MoSi2–Nb Josephson junctions. The Nb–MoSi2–Nb junction is an excellent system to study proximity coupling in junctions with rigid superconductor/normal metal boundaries by precisely and independently controlling the barrier thickness and the temperature. With regard to applications, the Josephson properties are very reproducible, and the characteristic voltage can be tuned easily over more than two orders of magnitude while still maintaining a practical critical current density. The characteristic voltage can be controlled within ±5% at 4K, with an exponential dependence on the barrier thickness. The proximity-coupled junction theory fits the temperature dependence of the critical current density, allowing us to quantitatively extract material parameters.
LABOUR MARKET DUALISM AND THE TRANSITION FROM TEMPORARY TO PERMANENT JOBS IN THE PROVINCE OF BOLOGNA

In this present study we are going to avail ourselves of figures regarding new employment and employment termination, registered at the Bologna Provincial Labour Exchange for the three-year period 2004-2006, in order to calculate the duration of job placements, according to the type of contract, and the likelihood of temporary workers being made unemployed: in order to do so, we shall utilise the survival curves method based on the Kaplan and Maier filter (Cox and Oates, 1984). Given the impossibility of estimating true transition matrices, in that the database fails to “cover” all outgoing events, the survival curves method at least enables us to estimate the “duration” of permanence in a given state. The utilisation of the Bologna Provincial Employment Centre’s records enables us to cover a sufficiently long period of time, which in turn enables us to obtain sufficiently stable estimates unaffected by contingencies. Clearly, the results may not be generalised for the whole of Italy, although they do nevertheless provide a meaningful insight into the situation of temporary workers (also given the healthy state of the Bologna province’s labour market).
EVALUATING GENDER-BIAS IN THE IRANIAN PRE-UNIVERSITY ENGLISH TEXTBOOKS

Textbooks can affect learners' attitudes, viewpoints, and their choice of language in second/foreign language (L2) communication. The various ways in which the people are displayed in communication may affect students' viewpoints. This study was an attempt to examine several potential areas of gender-bias in the representation of women and men in the pre-university English textbook, an English language teaching (ELT) textbook with two volumes taught in the high schools of Iran. To evaluate this textbook, content analysis was done in terms of gender-bias, gender-neutral, male-generics, and the firstness in the reading texts, instructions, exercises and illustrations. The frequency and percentages of names, nouns, pronouns and pictures attributed to each gender (i.e., males and females) were obtained and chi-square tests were carried out. In general, names, nouns and pictures pertinent to males outnumbered those attributed to females. Besides, there was a statistically significant difference between males and females in the two volumes of the pre-university textbook in terms of the above features. Also, male-oriented terms came first more frequently. However, there was not a statistically significant difference between male and female pronouns between the two volumes, though the percentage of male pronouns was higher. Moreover, the textbook included many gender-neutral nouns and pronouns not having any gender orientations. Findings indicated that the Iranian pre-university English textbook was somehow male-oriented and gender-biased as regards names, nouns, firstness and pictures associated with them though great efforts were made to avoid specific gender orientations.
Analysis of piezoelectric laminates by generalized finite element method and mixed layerwise-HSDT models

This paper presents a procedure to numerically analyze the coupled electro-structural response of laminated plates with orthotropic fiber reinforced layers and piezoelectric layers using the generalized finite element method (GFEM). The mechanical unknowns, the displacements, are modeled by a higher order shear deformation theory (HSDT) of the third order, involving seven generalized displacement functions. The electrical unknowns, the potentials, are modeled by a layerwise theory, utilizing piecewise linear functions along the thickness of the piezoelectric layers. All fields are enriched in the in-plane domain of the laminate, according to the GFEM, utilizing polynomial enrichment functions, defined in global coordinates, applied on a bilinear partition of unities defined on each element. The formulation is developed from an extended principle of Hamilton and results in a standard discrete algebraic linear motion equation. Numerical results are obtained for some static cases and are compared with several numerical and experimental results published in the literature. These comparisons show consistent and reliable responses from the formulation. In addition, the results show that GFEM meshes require the least number of elements and nodes possible for the distribution of piezoelectric patches and the enrichment provides more flexibility to reproduce the deformed shapes of adaptive laminated plates.
