数字化时代网络信息传播秩序重构的内在逻辑与行动策略

数字技术使信息传播渠道从单一向“网络立体化”转变,信息传播主体从“中心化”向“分散化”转变,信息传播环境从“真实化”向“拟态化”转变,信息传播出现了“混沌”与“失序”现象。“坚持人本理念”是网络信息传播秩序重构的基本逻辑,“信息资源与要素的再整合”是网络信息传播秩序重构的基础条件,“智能化信息平台决策机制”是网络信息传播秩序重构的保障。在信息传播秩序重构的过程中,需要强化技术体系与网络体系的链接,搭建多层次信息流动与传播的网络空间;需要加强对社会生活空间与产业的数字化改造,促使现实世界向虚拟世界迁移;需要催生全新的元宇宙信息场域,构建与现实世界映射与交互的虚拟世界。     

网络表达追责的法治理性研究

网络表达追责存在法条适用形式化、刑事政策偏重倾向：一是“社会秩序”“社会危害”认定的模糊性,表现为“社会危害性”解释的主观性,缺失“危害社会秩序”是否适合诽谤罪、“社会危害性”认定是否宜于采取优势证据标准的考量;二是以“寻衅滋事”追责须强化法条的实质性解释,强调援引“寻衅滋事”适用对象的明确性及法益取舍的恰当性;三是应当严格诽谤入罪条件,即以民事责任优先政策弱化检举不实言论的诽谤罪适用。     

罗兴亚问题对缅-孟关系和地区秩序的影响

罗兴亚问题是一个多世纪前英殖民者在亚洲埋下的诸多“民族问题”之一,也是孟加拉国与缅甸之间难解的“痼疾”。2017年8月以来,罗兴亚问题的再次爆发给相关国家造成巨大冲击。缅甸在打击罗兴亚暴力活动的同时,反对国际干涉,试图牢牢把握该问题解决进程中的主导权,而孟加拉国在政治、安全、经济和社会等不同层面基于自己的利益考量,寻求将罗兴亚人遣返缅甸,立场的对立使两国关系陷入僵局。而美国和印度介入罗兴亚问题则使地区秩序进一步复杂化,并在舆论和安全等领域影响中国的利益。2020年1月17日至18日,中国国家主席习近平应邀对缅甸进行国事访问,标志着中缅经济走廊从概念规划转入实质建设阶段,也给“罗兴亚问题”的解决带来新契机。     

Impact of support networks for breastfeeding: A multicentre study

Background

The rates of breastfeeding worldwide are slowly improving since 1996. Europe is still trailing behind the global breastfeeding incidence and prevalence rates. Thus, breastfeeding promotion, protection, prolongation and support have become an important challenge as breastfeeding sharply decreases in the first six months of life.

基于协高阶矩视角的沪港股市风险传染分析

金融风险传染(financial risk contagion)不仅是资产配置和套期保值决策中应该考虑的一个重要因素,而且直接关系着一国乃至全球金融体系的安全与稳定.运用协高阶矩(协偏度、协波动率、协峰度等)风险传染判定方法,实证检验了沪港通实施前后上海和香港两地股票市场间的风险传染状况.研究结果表明,沪港通政策实施后,上海股市向香港股市的第一类协偏度(均值→波动率)、协波动率、经调整的相关系数、协峰度等的风险传染统计量值依次变大,同样依据风险传染统计量值的大小,香港股市对上海股市的风险传染途径依次为协四阶矩(协波动率、协峰度)、第一类协偏度和经调整的相关系数,协高阶矩成为沪港股市间双向风险传染的主要途径;因资本净流动数额和投资者教育等因素,上海股市对香港市场的风险传染效应更强.     

New evidence about effects of reproductive variables on child mortality in sub-Saharan Africa

There is still considerable uncertainty about how reproductive factors affect child mortality. This study, based on Demographic and Health Survey data from 28 countries in sub-Saharan Africa, shows that mortality is highest for firstborn children with very young mothers. Other children with young mothers, or of high birth order, also experience high mortality. Net of maternal age and birth order, a short preceding birth interval is associated with above average mortality. These patterns change, however, if time-invariant unobserved mother-level characteristics of importance for both mortality and fertility are controlled for in a multilevel–multiprocess model. Most importantly, there are smaller advantages associated with longer birth intervals and being older at first birth. The implications of alternative reproductive ‘strategies’ are discussed, taking into account that if the mother is older at birth, the child will also be born in a later calendar year, when mortality may be lower.

Asymptotic behaviour of proportions of observations in random regions determined by central order statistics from stationary processes

In this paper, we show that proportions of observations that fall into a random region determined by a given Borel set and a central order statistic converge almost surely, provided that the corresponding population quantile is unique. We also describe three types of possible asymptotic behaviour of these proportions in the case of non-unique population quantile. As an application of our findings we establish limiting properties of numbers of ties with a central order statistics in a discrete sample. Our results are derived not only for independent and identically distributed observations but more generally for strictly stationary and ergodic sequences of random variables.
