文明1(civilized)、文明2(civilization)、文明3(civitas)——论“文明”一词的三种不同含义

学术界对于“什么是文明”存有争议的原因,是把文明(civilized)、文明社会(civilization)和国家(civitas)三个不同的概念混为一谈造成的。“文明1”大致相当于英语civilized(文明的)。文化是人群的生活方式,但是不仅彬彬有礼、琴棋书画、轻歌曼舞、美味佳肴是文化,愚昧粗鲁、恶俗陋习、野风蛮舞、吃糠咽菜也是生活方式,所以文明1不完全等同于文化,而只有被认可与受推崇的文化才被称为文明。无论古今中外,作为文化的文明1都是褒义的,文明1即“文明”的本义,也是对文化的价值判断。“文明2”相当于英语civilization(文明社会),摩尔根用以指称继蒙昧社会与野蛮社会之后出现的、高于蒙昧与野蛮状态的社会阶段。作为社会形态的文明2当然比蒙昧与野蛮社会要进步,但是文明社会并非一切都是文明的,其中充斥着种种不文明的蒙昧与野蛮,所以不能说文明2就是“文明的”社会。“文明3”相当于英语civitas(国家),是中国学者根据恩格斯的“国家是文明社会的概括”得出的概念,系指继部落联盟或酋邦之后出现的社会组织形态。因为不同国家的国体与政体各不相同,有了国家之后并非一切都变得比野蛮社会更文明了,所以作为国家的文明3也不都是“文明的”国家。

基于Civil3D的渠道工程参数化设计研究

针对渠道工程设计前期勘探时间长、二维计算过程繁琐、设计变更工作量巨大、现有渠道建模未考虑与地形数据联动等问题,提出一种基于Civil3D的渠道工程参数化设计方法,即以Civil3D为核心的渠道参数化设计关键技术,采用91位图助手获取勘察后的平面坐标,使用GlobalMapper对栅格文件中高程数据进行纠偏,通过ArcGIS整合、提取地形三维空间数据,并结合WPF窗体技术,以MVVM编程框架,开发面向对象的渠道参数化设计数据管理平台,拓展Civil3D参数计算及工程数据科学管理功能,为渠道参数化模型与三维地形模型的建立奠定基础。利用Atuodesk Subassembly Composer定制渠道横断面部件,通过建立目标参数及部件元素中的逻辑关系,实现渠道模型的参数化操作和与地形模型动态链接。实例应用结果表明,该技术可使渠道工程由二维设计过渡到三维参数化设计,优化了渠道设计阶段数据采集方面时间成本,降低了Civil3D使用难度,减少了设计变更产生的工作量,提高了设计效率,为水利线状工程参数化设计提供了参考。

Anti-Spoofing:Integrated Information Authentication of BeiDou-ⅡCivil Navigation Message

The BeiDou-Ⅱcivil navigation message(BDⅡ-CNAV)is transmitted in an open environment and no information integrity protection measures are provided.Hence,the BDⅡ-CNAV faces the threat of spoofing attacks,which can lead to wrong location reports and time indication.In order to deal with this threat,we proposed a scheme of anti-spoofing for BDⅡ-CNAV based on integrated information authentication.This scheme generates two type authentication information,one is authentication code information(ACI),which is applied to confirm the authenticity and reliability of satellite time information,and the other is signature information,which is used to authenticate the integrity of satellite location information and other information.Both authentication information is designed to embed into the reserved bits in BDⅡ-CNAV without changing the frame structure.In order to avoid authentication failure caused by public key error or key error,the key or public key prompt information(KPKPI)are designed to remind the receiver to update both keys in time.Experimental results indicate that the scheme can successfully detect spoofing attacks,and the authentication delay is less than 1%of the transmission delay,which meets the requirements of BDⅡ-CNAV information authentication.

Association between Mental Health Literacy and Workplace Well-Being of Chinese Grassroots Civil Servants:The Chain Mediating Effects of Regulatory Emotional Self-Efficacy and Resilience

This study aimed to investigate the relationship between mental health literacy(MHL)and workplace well-being(WWB)of Chinese grassroots civil servants,with regulatory emotional self-efficacy(RESE)and resilience as mediating variables.A questionnaire survey was conducted among Chinese grassroots civil servants,with a valid sample size of 2673 after excluding missing values and conducting relevant data processing.The PROCESS was used to examine the relationship between MHL,RESE,resilience,and WWB.The study found that MHL among grassroots civil servants was positively and significantly correlated with WWB(r=0.73,p<0.01).RESE partially mediated the relationship between MHL and WWB(β=0.25,95%CI[0.22,0.28]).Resilience partially mediated the relationship between MHL and WWB(β=0.22,95%CI[0.19,0.26]).MHL had a positive effect on WWB through the chain mediating effect of RESE and resilience(β=0.05,95%CI[0.03,0.07]).There is a close relationship between MHL and WWB,where Chinese grassroots civil servants with higher levels of MHL can develop stronger RESE and resilience,leading to higher WWB.The results of this study remind organizational institutions of Chinese grassroots civil servants that enhancing MHL,RESE,and resilience is an important pathway to promoting their WWB.

The Historical Position and Value Dimensions of Human Rights Civilization

Human beings are the mainstay and the ultimate goal of civilization.The history of human civilization is a continuous struggle to realize the respect,liberation,protection,and development of humanity.Human rights are an achievement of humanity and a symbol of progress,and the human rights civilization is an important component of human civilization.Understanding and interpreting human rights from the perspective of human rights civilization means that human rights are not only a concept or an idea but also a grand historical and long-term social practice.Up to now,the development of human rights civilization has roughly experienced four awakening eras:initialization,revolution,popularization,and globalization.In terms of its value dimensions,it has the characteristics of progressiveness,diversity,commonality,inclusiveness,indivisibility,openness,and so on.The historical position of human rights civilization and the development of its value dimensions have shown to the world that human rights are the common wealth of humanity,and human rights belong to all mankind;human rights are historical,concrete,and developmental;the concept of human rights is constantly evolving,and its connotations and categories are constantly expanding;achieving the free and well-rounded development of every person is the highest value realm of human rights civilization.The Chinese modernization endows Chinese civilization with modern strength and opens up new horizons for human rights civilization.The new pattern of human rights civilization to be created by Chinese modernization not only possesses the common characteristics of human rights civilization but also enjoys Chinese characteristics based on its own national conditions,enriching and developing the diversity of human rights civilization for all mankind.
