我国社会总供需平衡测算方式研究

在社会主义市场经济条件下,社会总供需及其构成的平衡,不仅是国民经济综合平衡的集中表现,而且也正日益成为新体制下政府宏观调控的主要政策目标。这一点无论是在我国经济学界还是统计学界,都早已成为共识。然而,在究竟应该采取何种方式来对我国社会总供需的平衡状况加以测算这一问题上,国内理论界却一直存在着“直接法“与“间接法“两大意见的分歧。无疑,这是一个关系到我国今后整个社会总供需平衡统计研究方向的重大

对完善我国股份制改造的思考

自1984年我国企业股份制改造试点工作开始,迄今已有十年的历史,企业的股份制改造也已成为经济体制改革中的热点问题。本文拟就我国股份制改造的现状、问题及发展谈几点看法:一、我国股份制改造的现实与问题改革开放以来,我国企业改革大致经历了三个阶段:第一阶段,1979年—1986年。

Chinese Color Nest Project: Growing up in China

随着中国进入老龄化社会,人口生育政策逐步放开,揭示脑与行为毕生发展的一般规律和常规模式(常模)正成为公共卫生和人口健康领域的重大基础需求.本文介绍&quot;中国彩巢计划&quot;(Chinese Color Nest Project&mdash;CCNP)这一在全国范围内分期分步地开展的项目规划,在10年(2013~2022年:http://zuolab.psych.ac.cn/colornest.html)内CCNP将积累毕生发展各年龄段的心理行为与脑影像样本,基于加速纵向实验设计方法建立中国人脑毕生发展的常模轨线.作为CCNP的发育项目&quot;成长在中国&quot;(dev CCNP:Growing Up in China)这一学龄儿童青少年脑与行为生长曲线项目,dev CCNP已经完成对重庆北碚区192名健康儿童青少年(6~18岁)的5年追踪.初步的研究结果表明,dev CCNP在实验设计、样本采集策略、数据获取和存储、初步发现和数据共享等方面具备长期实施的可行性,我国应及早部署开展儿童青少年的脑与认知生长曲线常模的大规模脑科学研究计划,提升中国在脑科学与医疗健康研究领域的国际实力和影响力,革新脑疾病临床实践.&nbsp;</p

Prediction of Energy Resolution in the JUNO Experiment

International audienceThis paper presents the energy resolution study in the JUNO experiment, incorporating the latest knowledge acquired during the detector construction phase. The determination of neutrino mass ordering in JUNO requires an exceptional energy resolution better than 3% at 1 MeV. To achieve this ambitious goal, significant efforts have been undertaken in the design and production of the key components of the JUNO detector. Various factors affecting the detection of inverse beta decay signals have an impact on the energy resolution, extending beyond the statistical fluctuations of the detected number of photons, such as the properties of liquid scintillator, performance of photomultiplier tubes, and the energy reconstruction algorithm. To account for these effects, a full JUNO simulation and reconstruction approach is employed. This enables the modeling of all relevant effects and the evaluation of associated inputs to accurately estimate the energy resolution. The study reveals an energy resolution of 2.95% at 1 MeV. Furthermore, the study assesses the contribution of major effects to the overall energy resolution budget. This analysis serves as a reference for interpreting future measurements of energy resolution during JUNO data taking. Moreover, it provides a guideline in comprehending the energy resolution characteristics of liquid scintillator-based detectors
