动态能力、结构洞位势与持续竞争优势——青岛红领1995-2018年纵向案例研究

选择在互联网时代成功实现转型升级的传统制造企业青岛红领为典型样本,基于其1995-2018年企业发展历程进行扎根理论分析,探讨企业持续竞争优势的来源。研究发现:企业在持续成长过程中,伴随着所嵌入结构洞网络的“开放-闭合-开放”的螺旋前进,其结构洞位势按照劣势、均势到优势方向进行递增演进;结构洞位势与动态能力相互作用共同演进,动态能力的形成是结构洞位势演进的基础,而更高阶的结构洞位势又会反过来促进企业动态能力的提升;结构洞位势与动态能力共同促进了竞争优势的形成。本研究基于动态能力和结构洞位势共同演进的制造企业持续竞争优势模型,为传统制造企业转型升级路径提供了理论指导。

网络治理的权力基础:一个跨案例研究

网络组织是当前经济活动中的普遍现象,网络治理并非信任基础上的自主治理,而是受组织间权力关系的规制,权力是决定网络组织运行的重要关系并影响了网络组织运行绩效。本文通过一个跨案例研究,分析了网络治理的权力基础,提出组织间权力来源于企业资源、结构位势和制度压力。三种权力基础的作用机理不同,其中企业资源和网络中心性显著地表现为个体层面的权力,而网络密度和制度压力则体现为网络层面的权力,个体层面权力与网络层面权力的相互作用导致网络组织呈现不同的演变趋势。

Periodic Structures of Rossby Wave under Influence of Dissipation

A simple barotropic potential vorticity equation with the influence of dissipation is applied to investigate the nonlinear Rossby wave in a shear flow in the tropical atmophere. By the reduetive perturbation method, we derive the rotational KdV （rKdV for short） equation. And then, with the help of Jaeobi elliptie functions, we obtain various periodic structures for these Rossby waves. It is shown that dissipation is very important for these periodic structures of rational form.

Structure of Some 4f Rare Earth Liquid Metals --A Charged Hard Sphere Approach

A well-established pseodopotential is used to study the structure of some 4f rare earth liquid metals （Ce, Pr, Eu, Gd, Tb, and Yb）. The structure factor S（q）, pair distribution function g（r）, interatomic distance r1, and coordination number n1 are calculated using Charged Hard Sphere （CHS） reference system. To introduce the exchange and correlation effects, the local field correction due to Sarkar et al. （S） is applied. The present investigation is successful in generating the structural information of Ce, Pr, Eu, Gd, Tb, and Yb 4f rare earth liquid metals.

STRUCTURE OF SOUTH ASIA HIGH IN THE STRATOSPHERE AND INFLUENCE OF ENSO

The structure of the South Asia High(SAH)in the stratosphere and the influence of ENSO on the SAH are systematically investigated with the long-term ECMWF reanalysis data.The results show that the SAH only exists in low levels of the stratosphere.The maximum intensity of the High is located at around 150 hPa and there is no obvious anti-cyclonic structure above 50 hPa.The axis of the SAH center tends to be northwest slanting from lower levels to higher levels.Further analyses show that the geopotential height and temperature fields of the SAH have dramatic anomalies during El Ni?o years and La Ni?a years. Corresponding to the ENSO,the SAH is weaker(stronger)at the warm(cold)phase.

Inner Structure of Statistical Gauge Potential in Chern-Simons-Ginzburg-Landau Theory

Based on the decomposition theory of the U（1） gauge potential, the inner structure of the statistical gauge potential in the Chern-Simons-Ginzburg-Landau （CSGL） theory is studied. We give a new creation mechanism of the statistical gauge potential, Furthermore, making use of the b-mapping topological current theory, we obtain the precise topological expression of the statistical magnetic field, which takes the topological information of the vortices.

Do networks of social interactions reflect patterns of kinship？

The underlying kin structure of groups of animals may be glimpsed from patterns of spatial position or temporal as- sociation between individuals, and is presumed to facilitate inclusive fitness benefits. Such structure may be evident at a finer, behavioural, scale with individuals preferentially interacting with kin. We tested whether kin structure within groups of meerkats Suricata suricatta matched three forms of social interaction networks： grooming, dominance or foraging competitions. Networks of dominance interactions were positively related to networks of kinship, with close relatives engaging in dominance interactions with each other. This relationship persisted even after excluding the breeding dominant pair and when we restricted the kinship network to only include links between first order kin, which are most likely to be able to discern kin through simple rules of thumb. Conversely, we found no relationship between kinship networks and either grooming networks or networks of foraging competitions. This is surprising because a positive association between kin in a grooming network, or a negative association be- tween kin in a network of foraging competitions offers opportunities for inclusive fitness benefits. Indeed, the positive association between kin in a network of dominance interactions that we did detect does not offer clear inclusive fitness benefits to group members. We conclude that kin structure in behavioural interactions in meerkats may be driven by factors other than indirect fit- ness benefits, and that networks of cooperative behaviours such as grooming may be driven by direct benefits accruing to indi- viduals perhaps through mutualism or manipulation
