经济增长方式与通货膨胀

改革以来，我国通货膨胀反复发生并有所加剧的深层次原因之一，在于建国以来形成的追求数量和速度的粗放型经济增长方式。经济增长方式难以完成由粗放型向集约型转变的事实表明，不能把发展才是硬道理理解成为速度才是硬道理。追求增长速度和扩张规模的增长方式必然引发通货膨胀和经济剧烈波动，国民经济发展战略只有真正建立在追求增长效益和发展质量的基础之上，才能保持持续、快速、健康的发展。     

A longitudinal study of grades in 144 undergraduate courses

This paper describes the trends in course-by-course grading at a large public urban university over a recent six-year period. To determine if systematic grade inflation was occurring, the study analyzed 144 individual undergraduate courses. Multiple linear regressions were fitted to more than 125,000 final course grades by courses. Most course grading patterns showed little evidence of systematic and homogeneous change over time. Hence, the increasing cumulative GPA for undergraduates at the institution studied was not caused by a general relaxing of grading standards. Rather, the supposition is that more students are moving away from traditional curricula into courses and degree programs which they find have grading standards reflecting their abilities and/or interests.Presented at the Annual Forum of the Association for Institutional Research, Houston, Texas, May 1978.     

2008年我国经济增长形势及政策建议

展望2008年,一方面经济增长环境良好,经济增长的内在动力依然十分强劲,本轮经济周期还处于上行阶段,我国经济仍将保持强劲增长的势头;另一方面,面对国际国内资源品价格起伏不定以及长期结构性矛盾等不利因素,在防范经济过热和全局通货膨胀的一系列宏观调控政策的作用下,2008年我国经济增速将有所回落,预计2008年的GDP增长大致在10.2%左右、工业增加值增长16.6%、城镇固定资产投资增长24.2%、社会消费品零售总额增长16.7%、出口增长24.1%、消费物价上涨4.4%。     

我国货币政策对抗通胀的效能评析

我国对抗通胀的货币政策工具主要是法定存款准备金率和贷款基准利率。从货币主义视角对存款准备金率和贷款基准利率的效能进行了评析，认为货币政策对抗通胀的效能非常有限，同时揭示了货币政策效能低下背后的实质问题，提出了相关政策建议。     

通货膨胀与通货膨胀不确定性——基于中国数据的实证研究

本文采用中国1952年至2010年的年度数据以及1993年第一季度至2009年第四季度的季度数据,基于AR（p）-EGARCH计量技术手段以及Granger因果检验实证分析了中国的通货膨胀与通货膨胀不确定性之间的关系。研究结果表明。中国高的通货膨胀水平将带来通货膨胀不确定性的增加,而通货膨胀不确定性增加也会进一步提高通货膨胀水平。根据研究结果,为了降低通货膨胀的社会成本,应该注重保持中国物价水平的稳定。     

中国通货膨胀率子成分惯性特征及其政策启示

在应用ARFIMA模型拟合CPI八大分类通货膨胀率时间序列基础上,采用脉冲响应函数测度我国八大类子成分的通货膨胀惯性,结果发现,CPI八大类子成分时间序列并不是一阶单整或者平稳过程,而是分数差分过程;CPI八大类子成分通货膨胀惯性特征与总体CPI表现不同。这意味着CPI各大类子成分在受冲击后持续时间长短不一,货币政策对各自的影响存在明显差异;值得警惕的是,由于食品类存在权重高和惯性大的双重因素,一旦其价格上升,无疑将给总体CPI带来较大压力。因此,货币当局在研究和制定反通货膨胀政策时不仅要关注总体的通货膨胀惯性特征,而且需要考虑CPI八大类子成分的惯性差别,有针对性地抑制推动通货膨胀的不利因素。     

投资项目评价指标应用探讨

在市场竞争的条件下,投资者在投资决策之前对拟投资项目进行科学的评价是至关重要的。利用净现值法和内部收益率法进行评价,在理论和实际应用中均存在不足之处,可以利用MIRR法来改进内部收益率法。通货膨胀对评价指标影响具有一定影响。目前流行的实物期权价值计算方法,实际是对净现值法的进一步发展,能够更加准确、合理地衡量项目的实际价值,提高决策的科学性。     

Leaving the “Big Deal” … Five Years Later

Southern Illinois University Carbondale (SIUC) and the University of Oregon each withdrew from several Big Deals with major commercial journal publishers from 2008 to 2010. Analysis of the impact of these decisions was originally conducted and reported in 2011 and 2012. This article provides updated analysis based on interlibrary loan statistics, financial savings, and impact on the collections. Results show that interlibrary loan of lost content still represents a small fraction of prior use, savings have been considerable, and the libraries have been able to address other needs in their collections because of the decision to withdraw.     

Taking a Cue in the Inner-City

This article uses a narrative analysis approach to explore the stories of student teachers' experiences developing a teaching persona during student teaching. In keeping with the narrative format, the researcher presents the participants' stories in a first-person narrative. The participants had similar experiences in the realm of developing their teaching personae: two common themes included their ideal versus actual personae and past and present influences on personae. Findings indicate that pre-service teachers carefully consider their teaching personae and draw on various sources to construct the personae that they believe will be successful.     

25 años: una propuesta desde el balance de una infancia y un aprendizaje

Resumen

El propósito de este trabajo es el estudio de los usos tempranos de las formas lingüísticas que permiten designar personas (hablante, oyente y otros). Se analizaron sesiones mensuales de interacción adulto-niño en contextos naturales. Las producciones lingüísticas de tres niños se analizan (rango de edad 1;4-3;0). Dos cuestiones principales guiaron los análisis: (1) el uso que los niños hacen de las formas lingüísticas disponibles en la lengua española para referirse a las personas y (2) las funciones comunicativas de esas formas. Los resultados muestran un uso temprano de distintas formas, aunque existen diferencias en a) la frecuencia con que cada niño se refiere a sí mismo, b) las formas que utiliza cada niño para referirse al mismo participante y c) el propósito comunicativo de cada forma. Estos resultados son consistentes con estudios anteriores que señalan la existencia de rutas individuales en la adquisición de la gramática. La importancia del estudio de las relaciones forma-función también se discute.
