In this article, we show that linearly normalized partial maxima of random observations from a three-parameter lognormal distribution converges weakly to a Gumbel distribution and establish a strong convergence theorem. We also discuss the asymptotic behavior of the number of near-maxima and sum of near-maxima random variables. 相似文献

2001年1月印度地震后,40名经过培训的EMDR治疗师援助了1600多人。儿童与成人均出现了PTSD的症状,但未发现人格解体症状。通过分析儿童的画可了解创伤对他们的影响,创伤越严重、丧失越多,个体的情绪就起伏越大,在那些较完整的较大的居民区,存在进一步被毁的威胁,在他们中间不安全感高于那些受破坏较大的地区。 相似文献

AbstractDespite the considerable number of papers addressing knowledge management (KM) aspects in supply chains, many research issues in the area are still neglected. One of the main research gaps in this field concerns the maturity level of KM practices adoption by small and medium enterprises (SMEs). This paper addresses this research gap by developing a framework to support the analysis of the maturity level of KM adoption in an SME context. The framework is applied in a multiple case study developed to investigate the extent to which SMEs operating in the food sector are deploying KM practices to support more sustainable initiatives. By relating KM maturity levels, perspectives and processes to sustainable practices concerning food waste and by-product synergies, the paper makes an original contribution to advance theory and practice in the area. The paper also points out potential barriers that companies face to implement sustainability-related KM practices. 相似文献

To deal with the problems of non-response, one-parameter classes of imputation techniques have been suggested and their corresponding point estimators have been proposed. The proposed classes of estimators include several other estimators as a particular case for different values of the parameter. A design based approach is used to compare the proposed strategy with the existing strategies. Theoretical results have been verified through simulation studies handling real data examples. 相似文献

AbstractSocial media supports the creative economy through its involvement in the adoption and appropriation of new innovation and accelerates economic growth. The current paper expands on this notion by identifying and analyzing the interaction between social media-based communities and small and medium enterprises (SMEs), as it examines how social media contributes to the knowledge co-creation and supports the adoption, use and appropriation of smartphones in South Asian countries, which are inhabited by approximately 1.6 billion people. The findings obtained through virtual ethnography (VE) provide insights into the dynamics and kinetics of knowledge co-creation and how that benefits large multinationals, small local businesses and consumers in developing societies. As such, we advance the knowledge management scholarship by presenting a holistic model of co-creation of knowledge involving multiple stakeholders. 相似文献
