福祉三角投向与人口流动实证研究

我国城镇化率自1996年末突破30%至2011年末突破50%,城市数量与人口获得极大发展,区域间人口的大规模流动现象也逐渐凸显。在地区差异的宏观背景下,目前的人口流动整体上具有东部向中西部地区回流、大城市间的转移,以及转移规模扩大化的趋势。进一步从福祉地理学角度进行剖析,产业人口更趋向于"工业增长极"流动、高素质人才则持续向东部及中西部一线城市的"人才高地"聚集,而人口流动也逐渐将社会与空间福祉纳入综合衡量,福祉诉求由"生存"向"发展"递进。未来,通过应用经济增长、社会公平与空间环境福祉三角的演替耦合规律,适度引导区域人口流动,可实现地区差距的收敛。     

Transcale average consensus of directed multi-vehicle networks with fixed and switching topologies

This paper contributes to solving a class of so-called ‘transcale average consensus’ problems for directed networks of vehicles with single-integrator dynamics. It generalises the idea of average consensus by taking into account the measurement scale of every vehicle's information state. Using the nearest neighbour-interaction rules, distributed algorithms are presented which are shown with the ability to achieve the transcale average consensus for directed networks associated with balanced graphs. Such consensus results are applicable to networks in the presence of both fixed topology and switching topologies, which are also illustrated via simulation tests. Moreover, improved algorithms and results of consensus are given for directed networks associated with unbalanced graphs.

Survival and other clinical outcomes of maintenance hemodialysis patients in Taiwan: A 5‐year multicenter follow‐up study

The increasing aging and diabetes mellitus (DM) patients in dialysis population make the quality maintenance of dialysis an imperative issue. Recently, an increasing number of dialysis centers were run by private dialysis providers, many of which apply quality assurance programs and performance management systems to dialysis care. We studied patients in dialysis facilities in Taiwan run by a private chain to see clinical outcomes of centers operating under these systemic strategies. Hemodialysis patients from January 1, 2008 to December 31, 2012 in 25 dialysis facilities in Taiwan, which received the management and consultation from a dialysis service provider, NephroCare (NC), were included. Data pivotal to quality of dialysis were analyzed. During a 5‐year interval, 5161 hemodialysis patients were included. For volume control, the proportion of patients with weight gain ≥4.5% decreases from 41.7% to 30.2%. Mean Kt/V is 1.74 ± 0.28. Mean albumin level is 3.92 ± 0.38 g/dL. Patients with phosphate <5.5 mg/dL is up to 71.8%. The mean hemoglobin level is 10.70 ± 1.40 g/dL. More than 80% of patients have adequate iron status. Further, 73% of patients use native arteriovenous fistula. Hospitalization‐free survival rate was 56% at the fifth year. Patient survival rate at the fifth year was 66.4%. Overall clinical performances were maintained very stable in NC facilities from this temporal data analysis. The hospitalization and survival rate also compare favorably with those reported internationally. These results warrant further studies to justify the application of this kind of quality assurance programs and performance management systems in dialysis care.

压合变形分析及整改措施

压合变形是压合模具的常见问题。但由于压合过程中,板件的受力方向、大小不断变化,另外影响变形的因素较多,部分问题的原因及整改方案不易确定。为了提高模具整改效率,更快的解决问题,需要有一整套的分析、验证、整改的思路进行引导。本文将围绕某车型前门总成压合时遇到的一个变形难题进行分析、验证、整改的论述。     

Combining balanced scorecard with data envelopment analysis to conduct performance diagnosis for Taiwanese LED manufacturers

Light emitting diode (LED) is a popular component to replace the traditional lighting source or advertising sign display. In 2014, high-brightness LED has a strong growth in backlight display, mobile appliances, automotive devices and outdoor illumination. However, emerging technologies in compound materials, epitaxying, packaging and new entrants result in a scale-based economy and intensively competitive environment. Inspired by the concept of business analytics, this paper proposes a novel framework to conduct corporate diagnosis for Taiwanese LED manufacturers: (1) balanced scorecard is fused with data envelopment analysis to address the impact of operational efficiency on performance outcomes, (2) financial and non-financial indicators are incorporated into the process of performance measurement, (3) the intricate causalities between key performance indicators (KPIs) and multiple outcomes (i.e. earnings per share and return on equity) are captured and (4) managerial insights are provided to indicate adaptive adjustment on significant KPIs. More importantly, a data-set comprising representative Taiwanese LED companies spanned from 2010 to 2014 is used to justify the validity of the proposed framework.     

Regular Ordering and Applications in Control Policies

In this paper we introduce the notion of regular ordering for periodic sequences based on the gaps between the entries. We define the notion of regular preserving functions using Schur convexity. This is used to extend some optimization results in queuing control problems. In particular, we show that the maximal traveling time in a stochastic event graph as well as the transmission times in a channel with redundancy, decrease (in the stochastic sense) when the input sequence becomes more regular.
