Effect and satisfaction of outpatient services by precision valuation reservation registration

BACKGROUND Due to improvements in living standards,people are now paying more attention to their health.In China,more patients choose to go to large or well-known hospitals,which leads to constant crowding of outpatient clinics in these hospitals.AIM To establish precision valuation reservation registration aimed at shortening waiting time,improving patient experience and promoting the satisfaction of outpatients and medical staff.METHODS On the basis of the implementation of a conventional appointment system,more reasonable time intervals were set for different doctors by evaluating the actual capacity of each doctor to receive patients,and appointment times were made more accurate through intervention.The change in consultation waiting time of patients was then compared.Correlations between the consultation waiting time of patients and the satisfaction of patients or satisfaction of medical staff were analyzed.RESULTS After precision valuation reservation registration,the average consultation waiting time of patients reduced from 18.47 min to 10.11 min(t=8.90,P<0.001).The satisfaction score of patients increased from 91.33 to 96.27(t=-8.62,P<0.001),and the satisfaction score of medical staff increased from 90.51 to 96.04(t=-10.50,P<0.001).The consultation waiting time of patients was negatively correlated with their satisfaction scores(γ=-0.89,P<0.001).The consultation waiting time of patients was also negatively correlated with medical staff satisfaction scores(γ=-0.96,P<0.001).CONCLUSION Precision valuation reservation registration significantly shortened outpatient waiting times and improve the satisfaction of not only patients but also medical staff.This approach played an important role in improving outpatient services,provided a model that is supported by relevant evidence and could continuously improve the quality of management.Precision valuation reservation registration is worth promoting and applying in the clinic.

Cross-Listing and Valuation Effects＂ Evidence From Nairobi Securities Exchange

The purpose of this study is to analyze the valuation effects of cross-listing. The study has conducted a univariate analysis of the Tobin＇s Q and the market-to-book ratio for the period before and after the cross-listing by using paired tests. Non-cross-listed firms are then included in multivariate regressions by using pooled Time Series Cross Section （TSCS） and Panel Corrected Standard Error （PCSE） regressions for a period of 13 years to find out if there is a difference in the valuations between cross-listed firms and non-cross-listed firms. The study＇s results indicate that the Tobin＇s Q of cross-listed-firms increases two years prior to cross-listing and that it continues to increase two years after cross-listing. The market-to-book ratios also show an increase two years prior to cross-listing and up to one year after cross-listing, then decrease in the second year after cross-listing. When non-cross-listed firms are included in the analysis, results indicate that cross-listed firms are valued higher than non-cross-listed firms. When data are portioned for positive earnings per share （EPS） and dividends, results indicate that valuation is the highest when EPS is positive. Since segmentation theories cannot be ruled out, the study＇s findings are more in support of the growth opportunity hypothesis.

A Structural Measurement of the Valuation Effect of China's External Assets:Method and Application

Existing research on the measurement of the valuation effect mainly follows the residual method proposed by Lane and Milesi-Ferretti(2001).This cannot be used to perform structural decomposition.We propose an aggregation approach rather than the residual method to measure structurally the investment flow and valuation effect of China's external assets.The results indicate that the valuation effect of China's external assets has been highly volatile and it was negative during the pandemic period.The structural decomposition shows that portfolio investment and direct investment made the main contributions to the valuation effect.The impact of exchange rates on the valuation effect has generally been higher than that of asset price in terms of direct investment and total external assets but the opposite has been true for portfolio investment.China's outward investments are currently more inclined to Asian countries and a few European countries but inflows to China still mainly come from developed countries.

Incentive and Entrenchment Effects of Large Shareholdings： Evidence from Chinese Public Corporation

This paper studies incentive effect and entrenchment effect of the largest shareholder. Author investigates 763 listed companies in SHSE, explores the statistical relationship between the largest shareholding and corporate performance. Author observes that the largest shareholder has the incentive effect and entrenchment effect on corporate valuation. Empirical relationship between the largest shareholding and corporate valuation shows that the firm value decreases with the equity ownership of the largest shareholders, consistent with a negative entrenchment effect, when the largest equity ownership is below 40.28% of the whole share. Then firm value rises when the proportion of the largest shareholder＇s rights was increased to 69.29%, being consistent with a positive incentive effect. But with the increase of the share of the largest shareholding, firm value falls again.

Acquisition Discount and Valuation Effect of Private M＆As in China

An acquisition discount can reflect not only the liquidity demands for unlisted targets but also the strategic requirements, management efficiencies and capital allocations for the listed bidders.Based on Officer(2007), the authors choose an acquisition approach to generate an acquisition discount for unlisted targets. In China, unlisted firms are sold at a deeper discount than listed firms. The deeper discount mainly depends on the liquidity demand and the characteristics of the bilateral trading components. Larger bidders tend to pay more, whereas smaller targets are sold at lower discounts. The values of unlisted targets in the TMT industry are underestimated. Furthermore, buying out unlisted targets can significantly increase the abnormal return of public bidders during the announcement period.Deeper discounts or stock payments have a positive effect on the stock values of the bidders, whereas this positive increase will be weakened if the bidder is large or has a previous ownership relationship.

数字化转型、宏观经济环境差异与股价崩盘风险

数字化转型有助于企业自身信息的释放,缓解投资者与企业、企业与产品供需市场之间的信息不对称,并使企业和投资者对宏观经济环境的变化更加敏感。文章在已有研究证明数字化转型能够降低股价崩盘风险的基础上,进一步提出数字化转型对股价崩盘风险具有非线性影响,选取2012年至2021年中国沪深A股上市公司为样本,实证检验企业数字化转型和宏观经济环境差异对股价崩盘风险的复杂影响。研究结果显示:与现有数字化转型能够减弱股价崩盘风险的相关研究不同,企业数字化转型对股价崩盘风险呈现倒“U”型影响,随着企业数字化转型加强,对股价崩盘风险的影响为先增大后减弱,并且当前众多企业数字化转型的影响处于倒“U”型的左侧,致使企业股价崩盘风险上升;在各地区和国家金融市场分割普遍存在的情况下,不同资本市场之间的估值差异、利率差异,以及汇率预期对股价崩盘风险均具有影响;数字化转型使企业与经济社会深度融合,能够调节宏观经济环境差异对股价崩盘风险的影响强度。

Valuation effects in China:scale,structure,and its function in external adjustment

At present China’s foreign assets are mainly denominated in foreign currencies,while a large part of foreign liabilities are denominated in domestic currency.Under this situation,the appreciation of domestic currency tends to have negative effects on net foreign assets through the valuation effect channel.This article gives a quantitative estimation of the scale of valuation effects in China and the research results show that the valuation effects in China are negative in the 20 years from 1982 to 2012.Furthermore,the scale of valuation effects has been increasing,which has lowered the scale of China’s net foreign assets.This paper also gives an estimation of the structure of the value effects,and finds that the volatility and the scale of asset price-related valuation effects are larger than that of exchange rate-related valuation effects.The results also show that the exchange rate has played a more and more important role in the fluctuation of value effects.Finally,this paper establishes an econometric model to value the function of valuation effects in the external adjustment and the results show that,during the period of 1981-2012,the role of valuation effects in China’s external adjustment were quite limited,but since 2007,valuation effects have played a more and more important role.

缓解热岛效应的城市聚合型绿色基础设施植物景观生态适宜度评价

城市聚合型绿色基础设施中的植物群落景观可以通过植物的降温和增湿作用,显著缓解热岛效应。然而,现有研究多聚焦于公园绿地的结构特征分析,而对热岛效应相关的公园绿地景观评价研究则相对不足。以苏州市白塘生态植物园为例,选取22个群落样方,以物种多样性、体感舒适度和空气颗粒物为准则层,物种个体数、物种丰富度、生态优势指数、Shannon-Wiener多样性指数、Pielou均匀度指数、综合舒适度指数和PM2.5数值等为指标层,结合层次分析法(AHP)和主成分分析法(PCA),以确定影响景观适宜性的关键指标及其权重,构建热岛效应导向下的景观适宜性评价体系,深入探究植物群落景观在缓解热岛效应中的作用。结果显示,Shannon-Wiener多样性指数权重贡献率最大,达22.48%;白塘植物园中55%的植物景观单元具有较高的适宜性,乔木种类多样性和乔灌比对景观适宜性具有显著影响,其中,当乔木种类超过5种且乔灌比接近6∶5时,景观单元具有较高的适宜性。根据研究结果,从地域性、多样性、层次性三个方面提出优化策略,旨在为城市热岛条件下的植物景观规划提供参考。

北京市平原百万亩大造林工程降温效应及其价值的遥感分析

随着城市化进程的加快,城市热岛效应已经严重影响到了城市居民的生产与生活。大量的研究成果证明,以植被和水体为主导的冷岛效应是减弱城市热岛效应的最有效、最持久、最经济手段,但过往的研究成果主要以城市公园作为研究对象,样本数量少,研究结果的不确定性大,对于大范围人工林地的冷岛效应关注较少。北京市在2012—2014年间实施了"百万亩平原大造林"工程,累计形成10648个林地斑块,这为人工林地冷岛效应问题的进一步研究提供了绝好的研究样本。利用2014年9月4日的landsat-8卫星影像数据,通过定量遥感手段反演了北京市平原区的地表亮温,并以造林地斑块的GIS数据为基础,对造林工程的降温效应进行了分析。结果表明,虽然造林时间短,但由于采用了大苗造林措施、公司实施模式,这些造林地的平均降温幅度可达1.023℃,其冷岛效应的辐射范围可到达林地边缘外350m,其中0—100m距离范围内的降温效果最为显著,达到了0.392℃。从降温效应的区域差异来看,延庆盆地造林地块的降温效果最显著,达到了3.519℃,6环以内造林地块的降温效果最小,只有0.111℃。通过不同年份造林地块的降温效应分析发现,造林地块的景观格局和湿地保护与建设工程类型的规模对林地斑块的降温效果有显著影响。从全部林地斑块的大小看,其呈现了数量上以小斑块占优、面积上以中、小型斑块为主的数量特征,降温效果则呈现了斑块规模愈大降温效果愈显著的特点。初步的价值估算表明,平原区大造林工程的降温效益达到了4.8882×10~8元,其中林地本身的降温效应占到了53.73%,林地外围辐射降温的效益占到了46.38%。在今后的造林工程实践中,要注意造林地块大小的设计问题,应以超大斑块和巨斑块为主体,同时要注意将林地斑块的空间邻接距离保持在100—500m的范围内,以充分利用林地斑块冷岛效应空间上的辐射扩散特点。

青藏高原草地存在价值研究——以玛曲为例

草地存在价值研究是强化人们环境保护意识的有力工具,也是制定资源利用战略的决策依据。运用条件价值评估方法中(Contingent Valuation Method,CVM)的最大意愿支付(Willingness to Pay,WTP)技术,对青藏高原东缘玛曲草地的存在价值进行了系统研究,结果显示:2005年,牧户的平均WTP为339元/a,总存在价值为0.03×10~8元/a;收入与WTP呈显著正相关关系。据此推断,2016年牧户的平均WTP为407元/a,总存在价值为0.033×10~8元/a。存在价值小,主要是因为当地人口基数小。如果考虑玛曲草地对全球生物多样性保育的贡献,以及对黄河水源所具有的涵养功能,则其总存在价值将倍增,其中2005年为636×10~8元/a,2016年为763×10~8元/a,增幅约为20%,与当地居民的收入增长相当。这一结果表明,与玛曲草地的保护成本相比,其存在价值极其显著,应纳入成本-效益分析之中;存在价值具有动态性,应根据收入变化状况进行连续评估,以反映其真实价值,从而确保政策制定者做出正确决策。

先前错失选项的数量对不作为惯性的调节机制

在以往涉及不作为惯性的研究中,个体通常只是错失了1个先前选项。本研究旨在考察当之前错失了多个选项后,不作为惯性是否仍会出现,并深入探讨估价和后悔因素在不作为惯性产生或消失中的作用。结果发现,先前错失选项的数量对不作为惯性具有调节作用:当先前只错失了1个选项时,出现了不作为惯性,当先前已错失了两个选项时,不作为惯性消失了。中介分析发现,这一调节作用可被预期后悔所中介。结果表明,预期后悔是导致个体在错失多个选项后不作为惯性消失的主要原因。
