Studies were initiated for two consecutive years to find out the effect of time of transplanting and seedlings hill^-l on the productivity of rice in Dera Ismail Khan district of North West Frontier Province (NWFP), Pakistan. The experiment was laid out in a randomized complete block design with split plot arrangements. Main plots consisted of four transplanting dates viz. 20th and 27th of June and 4th and 1 lth of July while sub-plots contained 1, 2, 3 or 4 seedlings hill^-1. Among transplanting dates, June 20th planted crop gave highest paddy yield and net return with I seedling hill^-1. It explains that the use of more seedlings hill^-1 not only adds to cost but is also a mere wastage of natural resources. Based on research findings, we conclude that the use of I seedling hill^-1 is most appropriate for timely sowing otherwise 4 seedlings hill^-1 should be used to compensate for the yield gap in late transplanted rice.  相似文献

Adult overhead athletes without a history of shoulder injury show scapular adaptations. There is a lack of detailed assessment of scapular kinematics in junior overhead athletes. This study aims to investigate three-dimensional scapular kinematics in junior overhead athletes. We recruited a total of 20 junior tennis players and 20 healthy children without participation in any overhead sports in this study. Bilateral scapular kinematic data were recorded using an electromagnetic tracking device for scapular plane glenohumeral elevation. The data were further analysed at 30°, 45°, 60°, 90° and 120° during glenohumeral elevation and lowering. Statistical comparisons of the data between groups (junior overhead athletes and non-overhead athletes) and sides (serve dominant and non-dominant shoulders of the overhead athletes) were analysed with the ANOVA. Comparisons showed that, in general, the scapula was more upwardly rotated and anteriorly tilted in overhead athletes when compared to non-overhead athletes, however there was no side-to-side differences when serve dominant and non-dominant shoulders compared in junior overhead athletes. The serve dominant arm of junior overhead athletes had alternations in scapular kinematics when compared with the non-overhead athletes. These findings provide clinical evaluation implications and the need for clinicians to assess for potential adaptations in junior overhead athletes.  相似文献

维吾尔传统文化以古丝绸之路的灿烂文化,即中原文化、印度文化、波斯文化、阿拉伯文化及古希腊文化等多种文化历史养分滋润、融合、成长,因此,维吾尔族民事惯例的形成有其深刻的历史背景和实践源流,原始自然崇拜、各种宗教信仰以及禁忌习俗为维吾尔族民事惯例的形成奠定了基础,成为维吾尔文化的重要部分。维吾尔族民事惯例不仅仅只是与伊斯兰教法有关,它是各种文化的融合体,并且,在维吾尔社会至今仍然起着重要的社会作用。  相似文献

Even though in the early years of the Republic of Turkey Darwin’s theory of evolution was treated as a scientific theory and taught fairly in schools, despite all the substantial evidence accumulated supporting the theory of evolution since then, Darwin and his ideas today have been scorned by curriculum and education policy makers. Furthermore, Turkish students and academics have been faced with unprecedented creationist propaganda for many years. In this paper, we first provide a glimpse of the theory of evolution and creationism in Turkey, we then report the results of our survey study (N = 1,098) about the undergraduates’ acceptance and understanding of Darwinian evolution and some of the socioeconomic variables affecting those measures. Our cross sectional study shows that acceptance and understanding of the theory of evolution is quite low. We criticize the current state of evolution education in Turkey and call for a change towards a scientific treatment of the theory evolution in schools.  相似文献

There have been ongoing criticisms of the field of educational leadership and management with respect to over-reliance on research from ‘Western’ contexts. However, evidence on the extent to which voices alternative to the dominant ‘Western’ discourse are represented in the international English-medium discourse of educational leadership and management is thin. Using a three-phase sequential mixed-methods approach, this paper explores knowledge production in the field by analysing the prevalence and impact of empirical articles published in four English-medium international journals. Additionally, the membership of editorial boards and editors is analysed to geographically locate key decision makers. Findings demonstrate that an exceptionally small set of core inner-circle Anglophone and non-inner-circle Anglophone settings enjoys disproportionate influence in the field. There is need for a knowledge base enriched with leadership and management practices from different sociocultural contexts and system structures with a multiplicity of voices to portray a more nuanced and balanced picture of leadership and management practices.  相似文献

Using survey responses from 1300 full-time employees in the Australian Telecommunications Industry, this paper explores the relative effects of task characteristics and sub-unit structure on aspects of information processing. Results of multiple regressions revealed that task characteristics have a greater impact on amounts and timeliness of information. In contrast, structural characteristics have greater effects on the degree of openness and accuracy of information. More specifically: (a) variety and task analyzability were found to increase the amount and timeliness of information; (b) greater sub-unit size tends to reduce openness and accuracy of information, while greater participation and formalization tend to increase these. Further scrutiny of these effects revealed that (a) the impact of structural characteristics on information accuracy and openness (i.e., section-level information processing) were strongly moderated by sub-unit size and (b) the effects of task characteristics on amounts and timeliness of information (i.e., individual-level information processing) were strongly moderated by the nature of the job, as strong differences between administrative, managerial, technical, and engineering positions were discovered in this regard.  相似文献

In this study, Artificial Bee Colony (ABC) algorithm is applied to the Automatic Voltage Regulator (AVR) system for obtaining optimal control. The tuning performance of this algorithm and its contribution to the robustness of the control system are also extensively and comparatively investigated. In the performance analysis, Particle Swarm Optimization (PSO) algorithm and Differential Evolution (DE) algorithm are used for the purpose of comparison. These analyses are realized by benefiting from different analysis methods such as transient response analysis, root locus analysis, bode analysis and statistically Receiver Operating Characteristic (ROC) analysis. Afterwards, the robustness analysis is applied to the AVR system, which is tuned by ABC algorithm in order to determine its response to changes in the system parameters. At the end of the study, it is shown that the ABC algorithm is successfully applied to the AVR system for improving the performance of the controller and shows a better tuning capability than the other similar population based optimization algorithms for this control application.  相似文献
