The random index is a strictly stationary renewal counting process generated by some negatively associated random variables. Using a revised large deviation result of partial sums, the elementary renewal theorem and the central limit theorem of negatively associated random variables, a precise large deviation result is derived for the random sums. The result is applied to the customer-arrival-based insurance risk model. Some uniform asymptotics for the ruin probabilities of an insurance company are obtained as the number of customers or the time tends to infinity.展开更多

The enterprise implementing the standardization is capable of flexible responding to customer＇s demands for the assortment, accelerates considerably research, and offers satisfactory delivery terms. That means the selection of types of the input factors and the method how to use them, the selection of working procedures and procedures of intermediary consumption, definition of the relations in the process of control, rational structure of the final products etc.. The permanent innovative atmosphere is presupposed.展开更多

Contrary to the claim that translation focuses only on reading and writing, this study presents anecdotal evidence showing that a learner-centered approach to translation can help foreign language students improve their speaking skill through group work, problem-solving, and cooperative learning. To this end, the paper presents practical examples of lexical, structural, textual, and cultural issues that students discussed in their process-oriented Arabic-English-Arabic pedagogical translation courses at the university level. The students were divided into groups of three or four to work together at all stages of the translation process. They spent most of the class time comprehending the source text, translating it, and discussing each other＇s target versions. In the remaining class time, the whole class discussed a target text translated by any one of the groups. The students were instructed to use English in their group and whole-class deliberations. They were also instructed to use the appropriate language functions, structures, and expressions to achieve objectivity in their arguments. The study calls for further empirical research to verify the usefulness of the proposed learner-centered translation-based technique of teaching speaking展开更多

Disappointingly, that objectivity does not extend to the policies that regulate that practice. This concern is demonstrated in the incoherence and lack of judgment that exist in media policy domains where journalism is confined to a deal between only the journalist and his or her audience. This linear process conspicuously excludes those crucial stakeholders whose interests tremendously affect the destiny of journalists and their audience. The development has adversely affected policy rationality in some developing countries as media policies lack interactive planning, robust policy discourses and stakeholder dialogue, thereby undermining policy integrity. This paper attempts to argue that for a media policy to be truly in public interest, formulators have to expand their horizon beyond government, journalists and their audience to other stakeholders. Newsmakers, who fall into a category of such stakeholders, can make the journalist＇s pen run dry if they go on strike! Others include media users, media owners and media scholars. The paper recommends the process of harnessing the perspectives of these stakeholders in a manner that can make analysts consider drafting a fresh all-encompassing media policy for developing countries, especially those of Africa.展开更多

The objective of the paper is to further understand value creation for the after-sales services. We present the case of the creation of a new business for the after-sales services for the entrance into a new market. The new business is created by two gurus in the aerospace industry. A typology of guidelines is derived, based on organizational and strategic perspectives, for the after-sales services value creation and the guidelines for the creation of a new business as well as for the entrance of into a new market are presented.展开更多

文摘The differences between two sequences of nonnegative independent and identically distributed random variables with sub-exponential tails and the random index are studied. The random index is a strictly stationary renewal counting process generated by some negatively associated random variables. Using a revised large deviation result of partial sums, the elementary renewal theorem and the central limit theorem of negatively associated random variables, a precise large deviation result is derived for the random sums. The result is applied to the customer-arrival-based insurance risk model. Some uniform asymptotics for the ruin probabilities of an insurance company are obtained as the number of customers or the time tends to infinity.
