摘要：从20世纪80年代开始,渠道联盟成为了营销渠道发展的一个重要方向,这当中,稳定性又成为联盟研究的一个核心内容。但渠道联盟稳定性的研究还鲜有学者涉猎,大部分学者集中于战略联盟稳定性研究,一部分学者专注于供应链联盟稳定性的研究。在解决联盟不稳定的策略上,上述研究要么过分关注“利益解决机制”,而忽视对“声誉解决机制”的研究;要么只关注了“纵向渠道联盟”的研究,而忽视“横向渠道联盟的研究。要保证渠道联盟的顺利运行,核心问题之一是依靠联盟成员间的相互监督、相互激励,而这种监督与激励是建立在联盟成员间信息的识别与传递之上的,声誉正是这种识别与传递过程的外在表现。声誉机制能约束和识别非合作成员,减少伪装合作成员数量,从而制约联盟内机会主义行为的发生,保持联盟的稳定,但声誉机制的发挥需要一定的条件。针对联盟成员合作出现的一些问题,笔者提出了维持渠道联盟稳定性的几点建议和需要进一步研究的问题。  相似文献   

Is decompressive craniectomy for malignant middle cerebral artery infarction of any worth？

Objective: Malignant middle cerebral artery (MCA) infarction is characterized by mortality rate of up to 80%. The aim of this study was to determine the value of decompressive craniectomy in patients presenting malignant MCA infarction compared with those receiving medical treatment alone. Methods: Patients with malignant MCA infarction treated in our hospital between January 1996 and March 2004 were included in this retrospective analysis. The National Institute of Health Stroke Scale (NIHSS) was used to assess neurological status on admission and at one week after surgery. All patients were followed up for assessment of functional outcome by the Barthel index (BI) and modified Rankin Scale (RS) at 3 months after infarction. Results: Ten out of 24 patients underwent decompressive craniectomy. The mean interval between stroke onset and surgery was 62.10 h. The mortality was 10.0% compared with 64.2% in patients who received medical treatment alone (P<0.001). The mean NIHSS score before surgery was 26.0 and 15.4 after surgery (P<0.001). At follow up, patients who underwent surgery had significantly better outcome with mean BI of 53.3, RS of 3.3 as compared to only 16.0 and 4.60 in medically treated patients. Speech function also improved in patients with dominant hemispherical infarction. Conclusion: Decompressive craniectomy in patients with malignant MCA infarction improves both survival rates and functional outcomes compared with medical treatment alone. A randomized controlled trial is required to substantiate those findings.  相似文献
