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。  相似文献

Abstract

The worsening of young people’s condition on the labour market has been described as a long-term trend of contemporary advanced capitalist economies. In recent years, the NEET (not in employment, education or training) label has been increasingly used to assess the integration of young people into the labour market. Does the NEET category adequately grasp the complexity of the underlying processes? In this contribution we will try to answer this question considering the Italian case as an extreme example. Focusing on the features of the youth labour market in Italy, we show the heterogeneity that lies behind the NEET concept, as well as its relationships with the labour market, the education system and welfare institutions. We argue that the institutionalization of NEETs as an analytical category may prove to be problematic as it may fail to identify specific vulnerable subgroups clearly, thereby leading to ineffective one-size-fits-all policy responses.  相似文献

This review discusses recent challenges to the welfare state arising from the Great Recession (GR). The GR was a significant event for social policy analysts, as it tested the responsiveness of welfare systems in the midst of a recent trend toward austerity politics in advanced economies. Social policy changes were part of the toolkit advanced democracies used to respond to the GR, and the welfare state mitigated the consequences of the GR. However, a stark limitation of the social safety net in the United States was the failure to assist immigrant households. The nexus of immigration and social policy is likely to be a significant controversy as we consider the meaning of social citizenship.  相似文献

1992年以来我国城镇居民居住消费的变化趋势   总被引:3,自引:0,他引:3  
1992年之后,我国明确了建立社会主义市场经济体制的目标,城镇住房制度改革取得了实质性突破,城镇居民居住消费发生了深刻变化。居民购房公平自由,私有住房的比重急剧攀升,住房设施日益完善,居住环境不断优化,居住开支迅猛增长,城镇居民居住水平获得了前所未有的提高。然而受不正确的思想观念的影响,在居民居住消费过程中,一些诸如住宅私有率过高、住宅面积过大、一房伴终身等严重脱离实际需要和基本国情的问题日益突出。  相似文献

银元主币流通与上海洋厘行市的更替   总被引:2,自引:0,他引:2  
邹晓昇 《史学月刊》2006,3(8):36-42
墨西哥鹰洋成为近代中国流通最广的银元主币,历时长达60余年之久。1914年后开铸的袁世凯像新币,逐渐取代鹰洋成为流通中的主币。上海钱业公所和其后的上海钱业公会深谙流通中主币的消长变化态势,审时度势,先后于1915年和1919年取消龙洋和鹰洋行市。鹰洋行市的取消进一步促使国币通行成为主币,使货币兑换市场逐步走向统一,降低社会交易成本;同时也为废两改元准备了条件,促进了近代货币统一化进程。  相似文献

明代科举各级考试的规模及其录取率   总被引:2,自引:0,他引:2  
郭培贵 《史学月刊》2006,(12):24-31
明中叶后,各省直的科考规模在四五千人至数万人之间,平均录取率估计在10%上下。乡试录取率,明初一般在10%上下;成、弘间定为5.9%;嘉靖末年又降为3.3%;而实际录取率又低于此。会试录取率,自洪武至万历中平均为8.6%;其中,洪武至永乐二年平均为21.7%,永乐四年至万历中期平均为8.4%。殿试规模和录取数在理论上皆等于同科会试录取数。永乐二年后,明廷共在51科14938名二、三甲进士中考选了1277名庶吉士,平均录取率为8.55%。上述录取率,都是在朝廷调控下形成的,并非完全自由竞争的结果。而之所以进行调控,又是由官缺的有限性和科举取士用途的单一性矛盾造成的。  相似文献

A noted specialist on the Russian economy presents an assessment of the impact of the global financial crisis on the mechanism of the country's economic growth. Focusing on the demand side of the economic ledger, the author explores the question of whether Russia will be able to re-attain the high economic growth rates of the period from 2000 to 2007 after recovering from the crisis. The paper analyzes the sharp drop in production in 2008 and the first quarter of 2009, attributing most of the damage to liquidity problems and declines in the price of oil. Empirical evidence is based primarily on data collected by the author from the Central Bank of Russia and the country's federal bureau of statistics (Rosstat).

A noted American authority on China's economy and monetary policy presents a statistical as well as theoretical analysis of a variety of perspectives on the controversy surrounding China's currency, basing his paper on both. The author provides the historical background and comprehensive summaries, focusing on different viewpoints about whether China's currency is undervalued, and thus may contribute to global imbalances. In the paper, he divides observers involved in the controversy into two main camps, namely the ones who find China's trade balances to be sensitive to price effects through exchange rate adjustments and those who emphasize other factors as bearing the responsibility for China's large surpluses, including the U.S. credit bubble emerging before the global financial crisis, as well as a version of Dutch disease.  相似文献

Between 1934 and 1939, over 5000 people, mainly ex-miners and their families, were settled in government-owned land settlements in England and Wales. This policy emerged as a response to mass unemployment, and complemented other schemes for the unemployed developed by the inter-war National Government. This paper will consider the geographical conditions that were imagined, realized and contested in these settlements. Acknowledging the hybrid and liminal nature of these spaces, the paper mobilizes new work in cultural and historical geography and draws out the heterotopic potential of the settlement programme.  相似文献
