关键词： 产业集聚   知识溢出   互动机制   联立方程  

摘要： 产业集聚和知识溢出是经济生活中的两种重要现象,两者是否存在互动关系?纵观现有的国内外文献,单独研究产业集聚和知识溢出的文献较多,关注两者互动关系的文献却并不多见。文章基于产业经济学和技术经济学中的相关理论,在深入剖析知识溢出促进产业集聚、产业集聚推进知识溢出以及两者互动机制的基础上,分别通过单方程模型、联立方程模型实证检验了产业集聚与知识溢出之间的单向关系和互动关系。最后根据理论分析和实证结果,提出促进产业集聚和知识溢出良性互动的对策建议,以期充分发挥产业集聚和知识溢出对区域经济发展的促进作用。

摘要： 目的对血清C肽与糖化血红蛋白联合检验在糖尿病诊断中的作用进行评价分析,为今后的临床检验工作提供有价值的参考信息。方法抽取2012年1月—2014年12月间我院收治的获得临床明确诊断的糖尿病患者76例作为观察组,另抽取同期健康体检者76例作为对照组,对其展开糖化血红蛋白、血清C肽、空腹血糖等指标的检测,并对检测结果进行对比分析。结果观察组患者平均糖化血糖蛋白(9.51±3.21)%、空腹血糖(8.85±2.12)mmol/L,较健康对照组的(5.09±1.98)%、(4.45±1.19)mmol/L显著升高(P<0.05),血清C肽水平(0.91±0.12)μg/L,较健康对照组的(1.55±0.19)μg/L显著降低(P<0.05)。结论糖尿病患者的糖化血红蛋白、血清C肽水平与健康体检者存在明显差异,因此可用于体检。这两项指标联合检测可为糖尿病的诊断提供可靠的参考信息,临床价值显著。

摘要： We explore the relationship between the 'theory of mind' (ToM) and 'central coherence' difficulties of autism. We introduce covariation between hierarchically-embedded categories and social information-at the local level, the global level, or at both levels simultaneously-within a category confusion task. We then ask participants to infer the mental state of novel category members, and measure participants' autism-spectrum quotient (AQ). Results reveal a positive relationship between AQ and the degree of local/global social categorization, which in turn predicts the pattern of mental state inferences. These results provide preliminary evidence for a causal relationship between central coherence and ToM abilities. Implications with regard to ToM processes, social categorization, intervention, and the development of a unified account of autism are discussed.

摘要： Objective Although the influence of trait internalization and state body satisfaction on appearance comparisons has been well documented, their interactive influence on comparison behaviours is unknown. Therefore, the present study thus tested a person X situation model in which both mood state and trait internalization interacted to predict engagement in upward comparisons. Method One hundred and forty-eight women aged 18 to 40 completed baseline measures of trait internalization, and then completed via iPhone app an experience sampling phase in which they reported momentary experiences of mood and comparison behaviours at up to 6 random times daily for 7 days. Results Multilevel analyses revealed that although upward comparisons were more likely for individuals who internalized the thin ideal (t = 3.27, P < .001), this effect was minimized in instances when a participant was satisfied with her appearance (t = -1.90, P = .031). Further exploratory analyses showed that state body satisfaction was a stronger predictor than trait internalization of comparison behaviours (R² = .14 vs. R² = .11) when the time lag between state body satisfaction and comparison event was less than 2 hours, but this pattern reversed as the time lag between state level predictor and outcome increased beyond 2 hours (R² = .09 vs. R² = .12). Conclusions Present findings suggest that bolstering one’s body satisfaction in the moment may be as clinically important as reducing a client’s interest in the thin ideal for alleviating occurrence of unhealthy body comparisons.

摘要： Introduction: This study examined whether aspects of parenting style (specifically, warmth, autonomy support, and coercion) moderated the association between parental involvement and adherence in youth with type 1 diabetes. Methods: Children ages 8 to 16 years with type 1 diabetes and a parent completed assessments of parental involvement, parenting style, and adherence. Results: Parent autonomy support and coercion were associated with adherence but warmth was not. Child report of more parental involvement was associated with better adherence. Warmth, autonomy support, and coercion were not moderators. Discussion: The findings underscore the importance of parental involvement, operationalized as responsibility for diabetes tasks, and parenting style, specifically coercion and autonomy support, for adherence in pediatric chronic illness management. Longitudinal research is needed to better understand how and why dimensions of involvement (e.g., responsibility, monitoring, support) vary over time and whether they impact outcomes differentially.

摘要： Batch-mode active learning approaches are dedicated on the training sample set selection for classification, where a batch of unlabeled samples is queried at each iteration. The current state-of-the-art AL techniques exploit different query functions, which are mainly based on the evaluation of two criteria uncertainty and diversity. Generally, the two criterions are independent of each other, and they also cannot guarantee that the new queried samples are identical and independently distributed (i.i.d.) from the unknown source distribution. To solve this problem, a novel form of upper bound for the true risk in the setting is derived by minimizing this upper bound to measure the discriminative information, which is connected with the uncertainty. And for the distribution match, the proposed method adopts the maximum mean discrepancy to constrain the distribution of the labeled samples and make them as similar to the overall sample distribution as possible, which helps capture the representative information of the data structure. In the proposed framework, the defining of the binary classes is generalized to a multiclass problem, in addition, the discriminative and representative information (DR) are combined together. In this way, our method is shown to query the most informative samples while preserving the source distribution as much as possible, thus identifying the most uncertain and representative queries. Meanwhile, the number of new queried samples is adaptive, and depends on the distribution of the labeled samples. In the experiments, we employed two benchmark remote sensing datasets the Indian Pines and Washington DC datasets and the results confirmed the superior performance of the proposed framework compared with the other state-of-the-art AL methods.
