大数据指数是否可以替代统计调查指数

2014年7月,澳盛银行首次将阿里巴巴系列指数纳入通胀观察标的,标志着大数据指数已经开始对传统的统计调查指数提出质疑和挑战。本文基于阿里巴巴aSPI指数和官方公布的CPI指数的比较研究,首次提出了aSPI指数显著优于CPI指数的一些基本特征;同时,通过实证分析对比了两种指数的同步性特征和分解性特征,即首先运用协整检验方法确定二者的同步性;其次通过EMD模型对二者进行序列分解,得出各自的波动成分和增长趋势;最后,在EMD对aSPI指数分解的基础上,通过Lasso回归估计了CPI指数。研究表明,随着对大数据研究的广泛性、科学性以及方法论和软件工具的进步,大数据指数对传统统计调查的佐证、补充乃至融合将会成为一种新趋势,通过实证、应用与发展,逐步产生新的CPI编制方法和分析体系,将是大数据指数理论和实践的根本出路。     

A study of the properties of Gaussian mixture model for stable isotope standard quantification in MALDI-TOF MS

The quantification of peptides in Matrix assisted laser desorption/ionization time-of-flight mass spectrum analysis coupled with stable isotope standards has been used to quantify native peptides under many experimental conditions. This approach has difficulties quantifying samples containing peptides with ion currents in overlapping (convolved) spectra. In a previous article we proposed a reparametrized Gaussian mixture model based on the known characteristics of the peptides that could also accommodate overlapping spectra. We demonstrated the application of our model in a series of single and overlapping peptides quantification experiments. Here, we focus solely on studying the properties of our approach and examine the characteristics of the GMM approach in convolved peptides using simulated spectra and provide a method for simulating these spectra.     

新生代农民工社会保障问题及其出路

新生代农民工是伴随改革开放而出现的一个新群体,其社会保障权利诉求比父辈们更为强烈,但现实情况是：他们的社会保障权益并没有得到多大改善。第一代农民工社会保障问题亟需政府承认并负担起补偿责任,而新生代农民工的社会保障问题需要国家通过相关法律法规为其搭建起社会保障的政策起点,厘清政府、用人单位和劳动者的社会保障权利、义务和责任,赋予新生代农民工平等的社会权利,同时要未雨绸缪地解决好与之相关的社会问题。     

大学办学特色与管理机制改革

＂《纲要》＂体现了大学特色和政府分类指导、创新管理机制两个方面问题的高度重视。大学的办学特色基本包含以下3个特征：独特性、创新性、稳定性。办学特色涉及人才培养多层面的因素,它不仅包括学校文化、教师＂教＂的质量、学生＂学＂的质量,还包括满足社会需要的程度。因此,目前应当积极推动以下两个方面工作：进一步深化教育管理体制和机制改革,建设多样化和多层次的高水平大学;制订社会保障政策,建立多元化的大学评价和认证体系。     

我国工业制成品的国际竞争力分析

我国工业制成品出口呈显著增长趋势并在出口贸易总额中占据绝对优势,其国际竞争力水平的高低成为人们普遍关心的问题。本文运用市场占有率、竞争优势指数、显示性比较优势指数及显示性对称比较优势指数等指标对我国工业制成品中的劳动密集型产品和资本、技术密集型产品进行实证分析,详细考察了近10年来出口工业制成品国际竞争力水平的变化趋势及特点,并提出贸易结构优化的合理方向。     

1930—1940年代上海现代市民小说的恋物特征

1930—1940年代上海现代市民小说在叙事形式上具有鲜明的恋物特征,主要表现在恋物的列举式修辞、物质人化和人的物化修辞策略、物质细节的表意功能与情节推动力。现代市民小说以一种空间化、恋物化特征标志了现代市民新的思维模式的诞生,也标志着现代市民深层价值观的转变。     

苦豆子种子中挥发油成分的分析

分别采用水蒸气蒸馏法（SD）和索氏提取法（SE）对宁夏地区苦豆子种子挥发油进行了提取,利用GC/MS比较分析了挥发油的化学成分,峰面积归一法得出各化学成分在挥发油中的百分含量。SD法共分离出29个色谱峰,鉴定出27种物质,占总峰面积的91.53%;SE法共分离出28个色谱峰,鉴定出23种物质,占总峰面积的98.61%。     

组织传播的审美特征

组织传播就是研究与组织相关的信息传播活动,具有极强的包容性、相关性、交叉性,涵盖了多学科并充分综合运用了多学科的理论原理。接受美学是20世纪60年代末产生的新理论学科,也称接受理论。其以受众与信息的关系为主体,研究受众对信息的理解、反应和接受,解读反馈,探究对信息产生不同理解的社会、历史和个人的原因。用美学的观点对组织传播的行为方式和特征进行研究,把握组织传播主体、受众审美活动的特点和规律,是现代传播学研究的一个重点。将组织传播与接受美学结合考察与研究,探讨两者的互动关系,有利于组织内部信息系统的构建和协调,是对传统美学鉴赏的有益探索。     

The Right Tools for the Right Job: Social Work Students Learning Community Development

The place of community development within social work varies across nations and time. The tensions in the 1970s in the UK gave way to decades when social work has been dominated by issues relating to protecting and caring for individuals. We now have a resurgence of community development activity, bringing together varied disciplines such as urban planning and health promotion as well as social work. Within the UK there are now requirements for community development knowledge and skills within qualifying social work training. This paper reflects on experiences in promoting community development practice learning in social work qualifying placements within Health and Social Care Trusts in Northern Ireland. Issues are raised about the diversity and complexity of expectations on qualifying training, and the challenges that face universities, colleges and employing organisations in developing practice learning in this curriculum area. The prospects for improving community development learning within both qualifying and post qualifying education and training are considered particularly in the light of inter-professional and inter-organisational initiatives that put community development in the context of health promotion, housing, crime, poverty and other social issues that might be addressed at community level to improve the health and social well-being of citizens.     

庄子“言不尽意”中的生命价值意识

庄子从作为万物之本原的“道”出发,把“意”放在整个“道”的系统中来观照,认为语言所表述的只不过是破坏了人之本性后一些经验性的东西而已。他认为人的本质即不为外物所累的“天人合一”,追寻的是一种真率自然的理想人格。这种持守人的本性的独特生命价值意识极为强烈地渗透在他的“言不尽意”观点的阐述中。
