跨国专利合作网络中技术接近性的调节作用研究

技术接近性对于企业间的跨国专利合作具有重要作用.基于多维接近性整体分析框架,采用中国电力系统技术领域2000年至2008年国外专利合作数据,分析技术接近性对其他接近性的调节作用.通过构造112家中外企业的专利合作网络,运用QAP网络回归方法实证检验跨国专利合作网络中技术接近性在地理接近性和社会接近性影响专利合作网络中节点连接距离和连接重要性过程中的调节作用.研究结果表明,在考虑多维接近性共同作用时,技术接近性对网络节点的连接距离和连接重要性具有重要影响,有助于节点之间构筑较短的连接渠道并形成较为重要的合作关系.除此以外,技术接近性还能正向调节社会接近性对连接重要性的正效应,但对于社会接近性与连接距离之间的关系没有显著的影响.由此验证了技术接近性可以影响其他接近性与跨国知识合作关系的基本假设,为进一步揭示不同接近性之间的相互作用机制提供了理论基础.     

小世界创新网络动态演化及其效应研究

低度、中度和高度开放的创新网络在创新集群创立和解体的动态演化过程中,其表现出的小世界性对创新绩效的效应有着较大差异． 创新绩效同创新网络小世界性间往往呈现倒U形关系,但该关系只在特定开放度下的创新网络演化到特定阶段才会显现: 低度开放的网络的小世界性同创新绩效的倒U 形关系在创新集群建立阶段显著,而在创新集群解体阶段不显著; 高度开放的网络则恰好相反; 在网络演化的其他阶段,小世界性对创新绩效并未构成显著影响． 这很可能是由于在创新绩效显著变化的阶段,创新个体的能动性较强,更倾向于接受新知识: 在低度开放的网络中,创新绩效显著上升的阶段主要集中于新的创新集群建立的阶段,而在高度开放的网络则主要集中于原有创新集群解体的阶段． 对中国专利合作发明数据的回归分析结果为该研究结论提供了实证依据． 因此,应当保持一个适度集聚的创新网络,以保证其不会传播过多冗余信息; 应在创新网络演化的不同阶段采用不同的开放策略,以充分利用高度和低度开放的创新网络演化到不同阶段所发挥的优势,同时,应当主动按照新兴技术下的新形势适当调整创新网络结构关系．     

基于网络结构-要素行为-创新绩效视角的国家创新体系国际化水平评价

将国家创新体系分解成科学研究网络、技术开发网络和技术扩散网络,从网络结构-要素行为-创新绩效的视角,选择具有代表性并且能够获取完整序列数据的指标构建国家创新体系国际化程度评价指标体系,利用主成分分析法确定指标权重,根据中国国家创新体系国际化的发展趋势以及参照美国国家创新体系国际化的相关指标值确定各指标的标准值。进而对中国进行了实证测算,2001~2010年间,中国国家创新体系国际化程度指数从14.7%提高到49%,其中高新技术产品进出口额比例、外资企业科技经费比例等指标的迅速增加是中国国家创新体系国际化程度快速提升的主要因素。由此,提出了提高中国国家创新体系国际化程度的策略在于高效的、紧密的、国际化的产学研协同创新。     

Adult Adoptees as Partners and Parents: The Joint Task of Revisiting the Adoption History

Adoption is unanimously considered a lifelong process, but adulthood and parenthood are life cycle stages that up to now have been explored only marginally. The principal aim of the present study is twofold: first, to analyze whether and how parenthood might lead the adoptee and his/her partner to reinterpret the adoption history and, second, to verify whether the attitudes of the two partners concerning adoption are similar or complementary. Thirty-four couples consisting of one adopted and one non-adopted partner, now parents, were interviewed and a graphic instrument, the Double Moon Test, was administered. Results revealed that most couples showed a shared attitude in valorizing both the origin background and the adoptive family. However, in a number of cases a divergent position emerged, highlighting the crucial role of the non-adopted partner in encouraging the adoptee to revisit his/her adoption history. Overall, the practical relevance of the research findings is discussed and future direction of research are suggested.     

‘La Lenin is my passport’: schooling,mobility and belonging in socialist Cuba and its diaspora

Based on an ethnographic study of transnational networks of alumni of an academically selective boarding school in Havana, this article explores the nexus between mobility, schooling and belonging in the context of socialist Cuba and its diaspora. Drawing on Goffman’s work, I argue that the boarding school experience was transformative; it facilitated or consolidated social mobility for its pupils, which later, for many, led to geographic mobility in the form of study and work outside Cuba. After graduating, alumni continue to identify with the school and to reproduce their alumni identities. The affective webs of belonging forged through family links and friendships fostered at the school constitute emotionally sustaining networks that also provide material support after migrating. I propose that the school represents a site of identification for a globally dispersed non-national diaspora and argue that migration scholars need to embed international migration within people’s lives more broadly.     

滇泰经贸关系的现状、问题与发展前景

滇泰经贸关系从纵向来看已经有了很大发展,但人横向来比,特别是与滇缅与滇越经贸关系,还不尽如人意。目前泰国尚未摆脱经济危机,影响了滇泰经贸关系的进一步发展。中国加入世界贸易组织以及东盟自由贸易区的即将建成为滇泰经贸关系取得新的突破带来了前所未有的机遇。     

‘What about the couple?’ Interracial marriage and psychological distress

We explore the association between racial composition of couples—that is, whether they are interracial or homogamous—and the psychological distress of their members, as measured in a screening scale for non-specific psychological distress. We use a pooled 1997–2001 National Health Interview Survey sample of the married and cohabiting population of the United States. We compare the odds of distress for interracial vs. same race married/cohabiting adults. There are several key findings. Interracial marriage is associated with increases in severe distress for Native American men, white women, and for Hispanic men and women married to non-white spouses, compared to endogamous members of the same groups. Higher rates of distress are observed for intermarried persons with African American or Native American husbands or wives, and for women with Hispanic husbands. Lower socioeconomic status explains approximately half of the increased distress experienced by white women, while higher socioeconomic status partially suppresses increases in distress for Hispanic men and women.
