The main aim of the current study were to find out the effect of competitive anxiety during the match for junior handball player students, and to investigate the relationship between the training experience of students and the level of competitive anxiety during the match for junior handball player students in youth centers of Duhok province in Iraq. A total number of participants was 128 junior handball players divided into 8 youth centers (Akre, Amedi, Bardarash, Domiz, Duhok, Shexan, Sumel and Zaxo) each center contain 16 players. The scale of the Competitive State Anxiety Inventory-2 was used to collect the data. The one way ANOVA, Test Least Significant Difference to find out the effect of competitive anxiety during the match for junior handball player students, and the correlation was conducted to find the relationship between the competitive anxiety and the training experience. The results showed that there is a significant differences between junior handball player students in the level of competitive anxiety for the youth centers (p < 0.00), and there is a negative significant correlation between the training experience and the level of competitive anxiety (r = ? 0.423, p = 0.00). This study would show useful information about the effect of competitive anxiety and training experience for junior handball player students.  相似文献

Variations over time in mortgage yield spreads should reflect changes in the underlying prepayment option value; moreover, the relationship between mortgage yield spreads and interest rate dynamics should weaken as the value of the borrowers prepayment option declines. We verify this hypothesis through an empirical analysis of residential mortgage yield spread behavior, and we also present evidence that the strength of the relationship between mortgage spreads and interest rate dynamics weakens (strengthens) as the level of default risk increases (decreases). This result is consistent with the competing risks effect between a borrowers option to prepay or default. Our results demonstrate the importance of accounting for mortgage price discount to par as well as default risk when developing time series of mortgage yields.  相似文献

Many traffic accidents take place throughout the world every day claiming lives as well as commodities and people involved in the accidents have to stay long periods at the hospitals. Traffic accidents are caused by many reasons. One of the reasons is the driver's having a heart attack just before the accident took place. If the heartbeat of the driver can continuously be measured, then most probably one of the reasons of traffic accidents can be eliminated. The designed model aims to measure the driver's heartbeat using infrared imaging. Some car models already have a driver heartbeat monitoring system and it measures the heartbeats by using the back seat electrodes. But these systems are expensive and unique to their models and what is more; its adaptation to other car models can pose a difficulty. Implementing on the car's rear-view mirror this new design monitoring system is very cheap and also it can be mounted to all motor vehicles easily.  相似文献

Cross-sectional data from the 1984 Farm Credit Corporation (FCC) survey are used to investigate the characteristics of farm operators who participated in the 1983 long-term agricultural credit market and to investigate the determinants of loan size. Discriminant analysis is used to analyze differences in socioeconomic characteristics among FCC clients, borrowers from other government agencies, borrowers from private sources, and nonborrowers, while regression models, adjusted for sampling bias, are used to reveal the determinants of size of long-term loans from the FCC. The results are tentative due to the cross-sectional properties of the data, but they seem to show that the Farm Credit Corporation is fulfilling its stated aims both in its selection of clients and in its tendency to grant larger loans to the clients it is mandated to serve. Les données sectorielles du sondage en 1984 de la Société du crédit agricole (SCA) sont utilisées pour examiner les caractéristiques des opérateurs d'exploitations agricoles qui ont participé au marché du crédit agricole è long terme en 1983 et pour examiner les déterminants de l'importance de l'emprunt. Une analyse discriminante est utilisee pour étu-dier les différences dans les caractéristiques socioéconomiques parmi les clients de la SCA, les emprunteurs è d'autres agences gouvernementales, les emprunteurs à des sources privées, et ceux qui n'empruntent pas, tandis que les modeles de regression, reajustes pour le biais de llechantillonnage, sont utilises pour reveler les determinants de 1'importance des emprunts a long terme à la SCA. Les resultats sont provisoires du aux qualites sectorielles des donnees, mais ils indiquent que la Societe du credit agricole semble accomplir ses objectifs enonces à la fois dans sa selection de clients et dans sa tendance à accorder de plus gros emprunts aux clients qu'elle doit servir.  相似文献
