网络嵌入对科技型中小企业绩效的影响

通过对网络嵌入、企业动态能力以及吸收能力概念以及作用机理进行深入剖析,并对126 家科技型中小企业 为样本进行实证分析表明,科技型中小企业网络嵌入对企业绩效具有显著地正向影响;网络嵌入对企业绩效的正向作 用是通过提升动态能力为中介作用而实现的, 即网络嵌入性程度越高,企业越容易形成较高的动态能力,进而提升本企 业绩效;吸收能力调节科技型中小企业网络嵌入与企业绩效的影响关系。     

魏晋时期武威地区少数民族的迁入及影响

魏晋时期,我国西北地区的河西走廊是一个少数民族聚集的地方。而地处河西走廊东端的武威,其最早的历史是由少数民族谱写的一部少数民族史,这里是一个少数民族相互交汇的地方。从早期的西戎、月氏、乌孙,到后来的匈奴、羌、鲜卑,还有自中亚而来的粟特人等,他们在这里生活、居住,不仅吸收先进的汉族文化,还带来了本民族文化为当时的武威注入了新鲜的血液。魏晋时期,武威迁入的各少数民族随着自身实力越来越强大,开始与汉人合作,积极参与到当地的生产生活中,甚至建立政权。文章以武威地区为例,论述这一地区内的民族关系整合,以及出现多元、一体的新格局。     

A critical discourse analysis of Gisela's family story: a construal of deportation,illegal immigrants,and literacy

In this paper, I use critical discourse analysis to analyze a student's narrative about the arrest, incarceration, and deportation of her mother to Mexico. The student, Gisela, was a fifth grader in my classroom during the 2008/2009 school year, and I encouraged the students to collect family stories from their relatives. Gisela created this story, and she wrote and illustrated this with the help of her father, student peers, and me. I draw on Gloria Anzaldúa's constructs of nepantla and nepantlera, narrative analysis, and systemic functional linguistics to show how Gisela's construed this story to create a powerful and creative narrative that disrupted autonomous forms of literacy along with the excluding and damaging discourses circulating about immigrants in our community.     

Regimes of language skill and competency assessment in an age of migration: the in/visibility of social relations and practices

This paper draws on ethnographic research to discuss the textual practices and social relations of language assessment. It examines the tensions that language educators and assessment practitioners encounter while making decisions about immigrant professionals’ language competence. It also analyzes the role of other social actors in constituting conceptions of skill. The paper concludes by considering social practice theory as an alternative for exploring conceptions of competence.     

Benefits for immigrant-origin and nonimmigrant-origin youth of discussing immigration in gender and sexuality alliances

In a time of unprecedented polarization in the United States, particularly concerning immigration, schools are uniquely positioned to help students understand the consequences of drastic policy changes. Beyond formal settings such as social studies classes, extracurricular activities may be important for fostering discussions about sociohistorical and policy issues. Such discussions could serve to empower youth from marginalized populations and raise their critical consciousness. Yet the potential outcomes of discussions in these extracurricular settings have not been studied in depth. Using data collected in school-based Gender-and-Sexuality-Alliances (GSAs) throughout Massachusetts during the periods leading up to and following the 2016 US Presidential election, we examined whether discussions of immigration issues in GSAs were associated with greater empowerment and critical consciousness among 580 youth (M _Age = 15.59, range = 10–20 years). Multilevel structural equation models showed that the frequency with which youth discussed immigration, relative to their fellow members, was positively associated with residualized change in perceived peer validation for members in general and with residualized change in hope for immigrant-origin members only. Contrary to our expectations, we did not find significant associations for critical consciousness. Findings suggest how groups addressing issues of equity and justice can promote members' empowerment.     

动态环境下组织冗余对企业探索的影响研究

以往学者往往关注组织冗余对企业绩效的最终影响,而对更为微观的企业探索的影响关注的较少。本文基于资源基础理论和惰性理论,以中国187个高科技制造企业为研究对象,检验了组织冗余与企业探索之间的关系。研究发现:(1)组织冗余对企业探索有显著的积极影响;(2)环境动态性对上述关系具有显著的负向调节作用。这一结果表明单一的理论视角难以全面解释组织冗余对企业探索的影响,将资源基础理论和惰性理论结合起来能增进我们对这一现象的理解。     

企业家社会资本、个人特质与创业企业绩效——基于中国创业板上市公司的实证研究

运用我国2011年151家创业板上市公司的年报数据,实证考察企业家社会资本和个人特质各构成维度对企业经营绩效的影响。研究结果表明:企业家教育水平、声誉威望和任职规模与创业企业绩效正相关,企业家政治参与度和职业经历与创业企业绩效负相关。     

混合动力汽车领域企业竞争力研究——基于专利分析视角

以220件混合动力汽车高被引专利为研究对象,运用社会网络分析方法,从点度中心度、中间中心度、核心-边缘结构和凝聚子群等角度对构建的网络进行分析。结果表明:美国和日本的一些企业在该领域的研发实力较强;企业网络中的小团体现象较严重,只有丰田等少数企业拥有较大竞争优势;各大企业的技术竞争点集中在动力系统、控制系统和蓄电池等方面。     

PE/VC网络特征与家族企业技术创新

选取1999²011年PE/VC共同投资事件,构建PE/VC联合投资网络,探讨PE/VC网络特征与家族企业技术创新的关系,研究发现:PE/VC介入的家族企业的R&D投入和专利产出均高于没有PE/VC介入的家族企业,且PE/VC投资的金额越多,家族企业的R&D投入和专利产出也越高;处于网络中心位置的PE/VC有利于提高被投资家族企业的R&D投入和专利产出;富含结构洞的PE/VC对新创家族企业的技术创新有正向影响;拥有较多间接联系的PE/VC对家族企业技术创新有正向影响。     

融资约束降低了中国研发企业的生存概率吗?

对应2000-2006年中国工业企业与中国海关进出口数据库,选取Kaplan-Meier生存与危险函数、Cox生存分析模型验证融资约束影响研发企业生存概率假说:中国研发企业通过缓解内源、外源融资约束,有助于提升自身生存概率。Weibull模型稳健性检验结果显示:(1)不同规模企业均能通过缓解内源融资约束提高生存概率,但只有大中规模企业能够通过增强外源融资能力延长生存寿命;(2)融资能力对研发企业生存概率的正向影响效应存在于金融发展水平较高地区,但这一效应并不显著存在于金融发展水平较低地区。因此,融资能力越强的中国研发企业生存概率越高,本文结论为延长中国研发企业生存寿命提供了新的启示。
