四川省农村区域经济差异分析

由于国家政策和地理位置等方面原因,我国各省区的农村区域经济发展存在较大差异,严重影响了全面小康社会的建设步伐。文章以四川省21个地级农村区域经济差异为研究对象,通过文献分析和建立数学模型的研究方法,对四川省农村区域经济差异的显著性进行分析,结果表明:(1)四川省农村区域经济存在一定差异,其中经济发展较快的城市为成都市、绵阳市。(2)对四川省区域经济发展测算得出:2010~2014年期间,区域三内部差异的波动幅度较大,范围在0.14~0.01之间,说明经济发展潜力较大。区域二内部差异呈"降低—增高—降低"的趋势,经济发展潜力一般;区域一由于地理位置和气候资源等因素限制,经济发展较慢。该研究为四川省农村区域经济的均衡发展提供理论参考。

浅论全面建成小康社会视域下的协调发展

协调发展观点作为整体发展思想的一部分由来已久,随着经济社会的发展,对于协调的重视程度也在不断加深。目前进入全面建成小康社会的决胜时期,作为全面小康题中应有之义的协调更是内涵丰富,意义重大,是建成全面小康的重要组成部分。它不仅包涵人与自然、区域、城乡的协调发展,还包括物质与精神两大文明、经济社会和国防领域间的协同发展。必须坚持把协调发展贯穿于发展各方面、全过程,才能使协调发展理念在促进新时代经济社会发展,做好全面小康这篇大文章上发挥出其时代价值。     

Clinical characteristics and resource utilization of patients with bipolar disorder who have frequent psychiatric interventions

Abstract

Objective:

To compare the demographics, clinical characteristics and resource utilization of patients with bipolar disorder who required frequent psychiatric interventions (FPIs) with those needing fewer interventions in the Duke Healthcare System database between 1999 and 2005.

Methods:

This retrospective analysis was conducted using electronic medical records of bipolar patients with FPIs, defined as having ≥4 clinically significant events (CSEs) in any 12-month period while in the Duke University Healthcare System. CSEs were composed of emergency room visits, inpatient hospitalizations, or a change in psychotropic medication due to psychiatric symptoms (score ≥4 on the Clinical Global Impressions–Severity scale). Data were compared between patients with and without FPIs.

Results:

Of 632 patients with bipolar disorder 52.5% were identified as having FPIs. These patients were younger and more often female and African American than those with fewer interventions (p?<?0.01 for all). Patients with FPIs were generally prescribed more psychotropic and non-psychotropic medications, utilized more healthcare resources and experienced more psychiatric co-morbidities than those who did not require FPIs (p?<?0.01 for all).

Limitations:

These results are from a single healthcare system and may not be generalizable to all patients with bipolar disorder. This analysis was retrospective and relied on availability of adequate information recording and coding of diagnoses by physicians.

Conclusions:

Patients with bipolar disorder who required FPIs were significantly different from those with fewer clinically defined interventions with respect to their demographic and clinical characteristics and prescribed medications.     

中国创业板上市公司盈利能力的因素分析——基于分位数回归的实证研究

影响上市公司盈利能力的因素有很多,不同的分位数水平下各因素对盈利能力的影响可能存在差异。传统的回归模型只能描述因变量的条件均值受自变量的影响,而分位数回归模型能够依据因变量的条件分位数对自变量进行回归,从而更加精确地描述自变量对因变量的影响。选取截至2013年6月30日的355家创业板上市公司的截面数据,从分位数回归的角度研究了不同分位数水平下各因素对公司盈利能力的影响,并且加入了地区虚拟变量,研究了区位因素与盈利能力的关系。     

上市公司财务危机预警模型分析

在后金融危机时代企业财务预警越来越受到重视,建立财务危机预警模型在理论上和实践中都有重要意义。本文选取了赢利能力指标、营运能力指标、偿债能力指标、成长能力指标、现金流量指标建立了主成分分析预警模型,该模型可以用来对企业财务危机进行预测。经实证研究表明:主成分预测模型在预测上市公司财务危机方面具有较好的预测能力。     

融合改进FT显著性与Grabcut的图像目标分割算法

针对目前复杂度较大的图像中目标分割速度较慢、显著性边界分割不明确等问题,提出了一种融合改进的FT（Frequency-tuned）显著性检测与Grabcut的图像分割算法。该算法首先通过改进基于频率调谐的FT显著性检测方法得到图像中显著性较高的区域,并利用SLIC（Simple Linear Iterative Clustering）算法对显著图进行预处理得到超像素图,能够有效改善边界的分割效果,然后通过以图论GraphCut算法为基础改进的Grabcut算法建立高斯混合模型。为了提高算法效率,通过聚类以超像素代替原像素,并反复迭代高斯混合模型（Gaussian Mixed Model,GMM）参数,最后利用最大流最小割算法得到最优目标分割结果。实验结果表明所提算法能够更准确更高效率地分割图像中的显著性目标,对高分辨率图像也有很好的适用效果,相比于其他算法在分割精度上提高10%左右,并具有较高的分割效率。     

Does china income FSDs follow Benford? A comparison between Chinese income first significant digit distribution with Benford distribution

Since Benford’s law is an empirical phenomenon that occurs in a range of data sets, this raises the question as to whether or not the same thing might be true in terms of the Chinese income distribution data. We focus on the first significant digit (FSD) distribution of Chinese micro income data from the 2005 Inter-Census sample, which corresponds to 1% of Chinese population and other micro income data from the China family panel studies (CFPS) and Chinese General Social Survey (CGSS). We use information theoretic-entropy based methods to investigate the degree to which Benford’s FSD law is consistent with the FSD of Chinese income data and our findings suggest consistency between the Chinese FSD income distribution and Benford’s distribution. The close connection between the two distributions has implications for the quality of the sample of Chinese micro data.
