基于情感分析的网络财经媒体通货膨胀预期研究

使用自然语言处理技术对网上财经文章进行与通货膨胀有关的情感分析,实验结果发现,使用无监督词典方法获得的系统分析结果,具有与通货膨胀显著相关关系,但提前期不明显;使用基于专家意见的监督训练方法获得的系统结果,相较通货膨胀具有1-3个月的提前期,能够为通货膨胀预期的度量提供实质性的支持,从而可以用于辅助宏观经济管理以及微观经济决策。     

通货膨胀预期行为特征与货币政策趋势——基于对货币流通、期货市场与房地产市场的计量验证

通过分析居民、企业部门的通货膨胀预期对消费和投资的影响,发现通货膨胀预期对总需求具有影响,具有较强不确定性的通胀预期引起产出更为显著波动,从而冲销政策效果。低通货膨胀引起的通胀预期对经济的负面影响较小,通货膨胀不稳定性则诱使通胀预期不稳定,并转而引致经济剧烈波动。为了更好实现预期的货币政策效果,必须将通货膨胀率控制在合理范围内,尤其要努力避免恶性通货膨胀的发生,由此中央银行货币政策操作有必要选择通货膨胀目标,使政策对通货膨胀预期产生锚定作用。     

Introduction

This article highlights the speakers and their topics presented at the MidSouth eResource Symposium held at Mississippi State University (MSU) Libraries on August 11, 2011. The Symposium was co-sponsored by EBSCO Information Services, North American Serials Interest Group's (NASIG) Continuing Education Committee, and MSU Libraries. Burdened with flat or decreasing budgets and the need for more digital collections driven by patron preferences, libraries continue to face many challenges. This year's Symposium presentations focused on the acquisition and management of e-resources, and provided attendees with knowledge of new and emerging technologies related to electronic resources and the digital environment.     

通胀感知与通胀预期的概念结构及综述

研究发现消费者具有有限的能力来存储和回忆物品的具体价格,他们感知和预期的价格和通货膨胀,即使是有一定程度偏差的,他们也似乎认为自己有能力去判断和预测通货膨胀。虽然研究人员已经提出了看似可行的解释,但他们是如何得到这些解释的,这还是个悬而未决的问题。     

认识我们的人格面具

面具,人人皆知,而人格面具,鲜为人知。了解荣格关于人格面．具的内涵、与自我的关系、形成、发展等问题,认识其积极和消极方面,有益于了解我们的人格名具,认识真实的自己,也对深入地分析社会各方面现象具有更多的现实指导意义。     

利用净现值在有风险和通货膨胀条件下的长期投资决策分析

在利用净现值进行投资决策分析时要考虑货币的时间价值 ,而货币的时间价值是在没有通货膨胀和风险条件下的社会平均资金利润率。实际中 ,项目的现金流量可能是名义现金流量 ,可能是实际现金流量 ;可能是肯定的现金流量 ,也可能是非肯定的现金流量。在进行投资决策分析时折现率与现金流量的指标口径应该一致 ,文章从仅有通货膨胀而无风险、仅有风险而无通货膨胀、既有风险又有通货膨胀三个方面探讨正确的投资决策     

Using Multiple Measures to Address Perverse Incentives and Score Inflation

The principle that important decisions should not be based on a single measure is axiomatic, if widelu ignored in practice. The traditional rationale is the risk of incorrect decisions from incomplete and error-prone data. The current high-stakes uses of test scores increase the need for multiple measures for two distinct reasons: the risk of score inflation and the potential for perverse incentives for educators and students. Addressing these two issues may require focusing accountability on measures of schooling as well as a much wider range of measures of student outcomes. The difficulties of pursuing this approach are described, and some possible directions for research and development are noted.     

群的矩阵的扩张

本文给出了一类特殊拟正则半群,即群的矩阵的膨胀的一系列刻划。在给出它的若干特征之后,指出这一类半群也是群的矩阵的幂零元—理想扩张,但反之未必成立。最后给出它的结构定理。     

System transition in Japanese short‐term higher education: what future for the Japanese junior college in crisis?

The uniquely Japanese institution of the tanki daigaku (two‐year university) known as ‘junior college’ in English was seen as Japan's answer to increasing participation in higher education. Initially established on a provisional basis in 1950, becoming permanent in 1965, they were the higher education institution (HEI) of choice of almost 500,000 students a year at their peak in 1995. Demographic changes after 1992 brought about a buyers' market for higher education with institutions in aggressive competition for students, a battle in which the tanki daigaku seems destined to be defeated. This paper examines the options available to junior colleges in crisis and in so doing identifies a number of features of a virtually universal system of higher education which raise issues for other advanced societies grappling with massification and commodification in their own higher education systems. The paper reviews the literature in this area, as well as drawing on a year of participant observation as an associate professor from 2000–2001.
