Evaluation of a Local Improvement-Oriented Project for Citizenship Education

Abstract

This article reports the evaluation of a four-year ESEA Title IV political/citizenship education improvement project conducted in elementary and secondary schools of a large, southern metropolitan school system. The project designed and tested an educational improvement model which conceptualized the school as a system with interrelated components which influence student learning. The model focused on classroom teachers as change agents and provided them with five types of support channeled through other parts of the system. The model was first found effective for secondary grades and later for elementary grades. Both process and product were monitored to provide research data on the model. The results, implications and limitations are discussed.

New developments in small molecular compounds for anti-hepatitis C virus (HCV) therapy

Infection with hepatitis C virus (HCV) affects approximately 170 million people worldwide. However, no vaccine or immunoglobulin is currently available for the prevention of HCV infection. The standard of care (SOC) involving pegylated interferon-α (PEG-IFN α) plus ribavirin (RBV) for 48 weeks results in a sustained virologic response in less than 50% of patients with chronic hepatitis C genotype 1, the most prevalent type of HCV in North America and Europe. Recently, reliable in vitro culture systems have been developed for accelerating antiviral therapy research, and many new specifically targeted antiviral therapies for hepatitis C (STAT-C) and treatment strategies are being evaluated in clinical trials. These new antiviral agents are expected to improve present treatment significantly and may potentially shorten treatment duration. The aim of this review is to summarize the current developments in new anti-HCV drugs.     

对新派上海话人称代词复数形式的重新分析——兼谈标记“拉”的语法语音地位

在词汇系统中,人称代词被认为是发展变化最为保守的词类,因此在研究中通常倾向于借由共时层面的语料去追溯历时的原型。然而吴语的人称代词系统却往往在形式上表现得参差不齐,难以循其规律。作为吴方言一支的上海话,其人称代词也同样具有这一特性。本文就此观点展开讨论,并在总结现有研究的基础上进一步对新派上海话的人称代词复数形式进行重新分析。同时对上海话复数人称代词中标记"拉"的语法、语音地位进行了考察和剖析,提出了有待进一步研究的课题。
