We present original empirical Bernstein inequalities for U-statistics with bounded symmetric kernels q. They are expressed with respect to empirical estimates of either the variance of q or the conditional variance that appears in the Bernsteintype inequality for U-statistics derived by Arcones [2]. Our result subsumes other existing empirical Bernstein inequalities, as it reduces to them when ...
Article history: Received 16 November 2005 Received in revised form 10 November 2006 Accepted 10 November 2006 Herman E. Daly noted in 1992 that maintaining the scale of the physical economy within ecological capacity is vital in pursuing sustainability, leading to the use of biophysical assessments as a central concept in sustainability analysis from the perspective of ecological economics. Ac...
as polysemy is encountered frequently in english as foreign language. fl learners’ ability to disambiguate polysemous verbs becomes critical to their comprehension in the target language. this thesis, accordingly, investigated how iranian efl learners achieved comprehension of english polysemous verbs by using three different types of cues: (1) elaborated context, (2) semantic frames, and (...
در این مقاله a و b جبرهای باناخ یکدارند و فرض می کنیم m یک b,a- مدول باناخ یکدار باشد پرفسور فورست و مارکوس جبر باناخ مثلثی t را مورد مطالعه قرار داده و نشان داده اند که t به طور ضعیف میانگین پذیر است اگر و تنها اگر جبرهای گوشه ای a و b به طور ضعیف میانگین پذیر باشد. همجنین در این مقاله ابتدا نکاتی در مورد میانگین پذیری مدولی، نگاشت مدولی، اشتقاق مدولی و... بیان شده و سپس در رابطه با اشتقاق مدو...
Extant research concludes that family firms are less likely to bribe due reputation concerns. However, such conclusions are, a certain extent, inconsistent with the intuition and observation some can be aggressive bribers. This study employs restricted-extended framework of socioemotional wealth model reconcile this inconsistency. We propose management, on one hand, results in preservation will...
monumental changes occurring on a daily basis have altered the world into a global village of expanding technology and shrinking geography in which preparing language learners for intercultural communication seems to be a sine qua non for modern language education. employing a cross-sectional design in its first phase, this study investigated the intercultural sensitivity and language proficien...
in new management approaches, in the organizations with inflexible structure, existing of red tapes and interruptions caused by limitations and also non-compliance with environmental changes, create demotivation among staff. with regard to the influence of job motivational potential and its relationship to the type of organizational structure( enabling and dissuasive), the goal of this research...
hedging is a multi-purpose rhetorical strategy which is usually used in scientific arguments to secure ratification of claims, reduce the risk of negation, avoid conflict, manage disagreement and leave room for the audience to assess presented information. hedges are frequently used in research articles to mitigate the findings of research endeavors. the present research aims to investigate the...
We derive moment inequalities for the supremum of empirical processes of U-Statistic structure and give application to kernel type density estimation and estimation of the distribution function for functions of observations.
The problem of ranking/ordering instances, instead of simply classifying them, has recently gained much attention in machine learning. In this paper we formulate the ranking problem in a rigorous statistical framework. The goal is to learn a ranking rule for deciding, among two instances, which one is “better,” with minimum ranking risk. Since the natural estimates of the risk are of the form o...
