四川区域中心馆藏文物保存环境监测平台常见故障分析与改进措施

四川省馆藏文物保存环境监测区域中心(简称四川区域中心)平台,经过两年多的运行实践,实现了12家博物馆监测站的集成联网。本研究分析了区域中心监测平台运行中常见故障现象的表现形式、故障原因及故障率。结果表明:监测平台的主要故障现象为传输异常和数据异常;除温湿度外的其他监测终端故障率较高;软件平台建设也不够完善,导致数据利用率低,尚不能实现风险评估、预测预警和预防调控等管理功能。针对分析发现的问题,提出一些相应的技术措施和管理措施,为有效降低故障的发生率,提升国内区域中心平台建设提供一定的指导和参考。     

The Rise in Power of Crown Prince Mohammed bin Salman

Crown Prince Mohammed bin Salman is moving across the international stage as the future King of Saudi Arabia. He has the support of his father, Saudi royals, and the oil income of his country. He also has 10‐year plan he agreed upon with the King called Vision 2030. The three components of the Vision are to diversify the oil‐based economy to include technology and tourism, to make the country the heart of Islam and Arab culture and to become the economic and geographic hub of Asia/Europe and Africa. His rise in power will depend upon his skill in expanding the religious tolerance of Saudi people, the current economic structure of the country, and the education of the youth. He is simultaneously addressing all these challenges in order to cement the country's future sustainability. Suggestions for enhancing his multifaceted impact on his country are provided.     

马来西亚城市华人移民就业情况研究——基于2005年在马来西亚实地调查的分析

基于2005年在马来西亚吉隆坡和新山实地调查获得的资料,从城市移民在行业分布、职位、就业或经营途径、收入和政府经济政策等各个方面的情况,探讨了华人与马来人城市移民的不同遭遇,比较了华人移民在吉隆坡和新山这两个不同类型城市中的不同境遇。得出结论:城市新移民中马来人比华人获得了更多的政策扶持和发展机会,但华人比马来人拥有更多的投资方式和自己的企业,在城市中华人比马来人受访者的月收入要略高一些;在不同的领域,华人新移民在新山和在吉隆坡的就业或商业机会不同。     

The minimum wage and seasonal employment: Evidence from the US agricultural sector

Nearly 40% of agricultural workers in the United States earn an hourly wage that is within 10% of the prevailing state-level minimum wage. We evaluate the impact of the minimum wage on farm employment using county-level data from the United States Census of Agriculture. We employ long-differences specifications and find evidence of a dynamic, negative effect of the minimum wage on seasonal agricultural employment, but no effect on year-round agricultural employment. We estimate a long-run elasticity of total agricultural employment with respect to the minimum wage of about −0.40, which is both statistically and economically significant. Employers’ total expenditures on hired agricultural workers are not affected by the minimum wage. Finally, our analysis suggests that increases in minimum wages may lead to higher capital investment as well as the consolidation of farming operations in the agricultural sector.     

近半个世纪以来中国城市化进程的总结与评价

与国际标准模式相比较 ,中国的城市化水平略低于经济发展水平 ,严重滞后于工业化水平 ,这一现象是中国独特的工业化道路造成的 ;2 0世纪 80年代以来中国城市化进程明显加快是产业结构和就业结构转换的客观需求 ,而且一直到本世纪中叶中国将一直保持这一趋势。     

近代皖北交通中心变迁再探--以津浦铁路淮河大桥选址变更为中心

临淮关凭借传统交通与商业中心的地位,成为津浦铁路淮河大桥桥址的首选之地,但由于该处地势低洼,不易建桥,桥址最终选定在蚌埠。蚌埠得津浦铁路和淮河水运之利,迅速崛起,成为皖北地区新的交通与商业中心,而临淮关则渐趋衰落,最终成为淮河岸边一个普通小城镇。究其原因,主要是由于桥址变更,引起交通区位优势的转换,蚌埠的交通优势转化为产业优势;铁路与淮河水运在蚌埠的有机结合以及政治因素的助推。     

Professional Workers in a Risk Society

This paper contributes to the debate on the utility of Ulrich Beck's (1992) notion of the 'risk society' for understanding the positions and experiences of workers who are negotiating more 'flexible' employment contracts. Whilst previous articles in this journal have concentrated upon the lower end of the employment market, I aim to broaden the scope of the discussion by focussing upon professional freelance magazine workers, and ask whether Beck's framework has a different utility in terms of understanding their employment security and risk.¹     

高校旅游毕业生就业统计范围问题研究

由于观念与技术等问题,我国现行的高校旅游就业统计范围,在专业和行业界定上存在着明显不足,以致人们对于旅游学科在教育体系中的地位以及旅游教育的投入与产出的认识出现严重误解。科学运用旅游卫星账户,参考相关旅游增加值,正确统计高校的旅游就业范围,符合国民经济就业统计的实际需要,也有利于端正人们对旅游就业范围的客观认识。     

响应社会需求的旅游动态课程体系构建研究——以云南民族大学旅游管理专业为例

20多年来,旅游管理课程体系建设取得很大成绩,但依然存在课程老化固化、缺乏对社会需求响应能力等问题。通过往届毕业生、网络、新业态和旅游组织机构等多端口的职业需求信息的监测与评估,在理论和技术上可以构建一个既能响应社会需求,又能满足学生个人兴趣,还能符合国家专业要求的“三位一体”的响应社会需求的旅游动态课程体系。通过该课程体系的建设可以加强现有专业对社会需求的响应能力,减少一些短周期新专业的应急性增设,从而节约教育资源、积累教育资本、避免学生同业竞争、缓解就业压力。基于以上理论和实证研究,云南民族大学旅游管理专业未来至少可以增设美食与营养、旅游技术与工程两门课程以响应社会需求,并形成其核心竞争能力.
