试析旅游职教集团协同合作的制度设计

随着我国职业教育改革的不断深入,职业教育集团作为职教改革的新生事物,有效地整合了区域教育资源,实现了优势互补和共建共享,但目前职教集团也存在合作乏力、组织结构松散等突出问题。该文以旅游职教集团为例,从组织社会学视角分析目前职教集团合作乏力的关键在于合理的制度设计,当前职教集团组织结构松散,难以发挥集约效应,影响协同合作的效果。应将职教集团运行制度设计为公共服务平台,建设成为师资共享平台、学生实习平台、校企实训平台、科研创新平台、人才供需平台和导游技能资源库,形成各方获益的共建共享和共赢平台。

An algebraic theory of portfolio allocation

Summary. Using group and majorization theory, we explore what can be established about allocation of funds among assets when asymmetries in the returns vector are carefully controlled. The key insight is that preferences over allocations can be partially ordered via majorized convex hulls that have been generated by a permutation group. Group transitivity suffices to ensure complete portfolio diversification. Point-wise stabilizer subgroups admit sectoral separability in fund allocations. We also bound the admissible allocation vector by a set of linear constraints the coefficients of which are determined by group operations on location and scale asymmetries in the rate of returns vector. For a distribution that is symmetric under a reflection group, the linear constraints may be further strengthened whenever there exists an hyperplane that separates convex sets.

Why (not) cooperate? A cognitive model of farmers’ intention to join producer groups in Romania

After the breakdown of the communist regime in Romania, collective farms were replaced by a large number of small-scale private farms. Although cooperation seems to be a favourable choice for these smallholders, it did not develop as perhaps expected. This article explores the factors that determine the formation of the intention of Romanian vegetable farmers to join marketing cooperatives in the form of so called producer groups. Our theoretical framework refers to Ajzen’s Theory of Planned Behaviour, which we model with a structural equation model. We identified as main intention drivers the expectation for better prices and easier access to capital. Perceived family support is another significant factor. The level of distrust is high. Although our trust variable is not significant as a predictor of the intention to cooperate in the model, we find qualitative indications that trust plays a role when the intention is translated into actual behaviour.

一种新的机器人自组网群组运动控制模型

针对现有机器人自组网运动控制模型无法真实反映机器人运动规律的问题,提出一种新的群组运动控制模型(group movement control model,GMCM)。该模型基于机器人通用运动学模型,采用群组控制算法,对传统群组随机运动模型——参考点群组运动模型(reference point groupmobility,RPGM)进行修改,可描述机器人编队解散和集合的运动状态,满足群组分割与合并的需求。进一步实现GMCM模型,并基于GMCM,RPGM,DRGM模型对机器人自组网路由协议进行模拟仿真。结果表明,基于GMCM模型仿真时协议性能有所降低,较为真实地模拟了机器人编队运动,对机器人自组网的研究具有一定的参考价值。
