Land markets and migration trends in Tanzania: A qualitative‐quantitative analysis

While migration has been found to enhance welfare across a range of settings, most of the literature focuses on rural‐to‐urban migrant flows. Using a unique dataset from north‐western Tanzania, this article probes an important, yet overlooked, link between land markets and rural‐to‐rural migration. A mixed‐methods approach is used to discern how these two forces are intertwined in village life. Results indicate that household decisions to migrate are particularly influenced by the ease of market‐based land access in their new communities. This suggests that labour mobility may be facilitated through the development of a well‐functioning land market.

Benchmark Analysis: Shopping with Proper Confidence

We discuss the issue of using benchmark doses for quantifying (excess) risk associated with exposure to environmental hazards. The paradigm of low-dose risk estimation in dose-response modeling is used as the primary application scenario. Emphasis is placed on making simultaneous inferences on benchmark doses when data are in the form of proportions, although the concepts translate easily to other forms of outcome data.

早期行为主义政治学研究方法的演变及其基本特征

出于对传统政治学研究方式的不满,早期行为主义政治学在研究方法和内容上发生重大转变。早期行为主义政治学不仅经历了从价值研究转向事实研究,从定性研究转向定量研究,从静态研究转向动态研究的过程,其研究内容也从制度研究逐渐转向政治行为研究,并深受心理学和社会学的影响。但是,早期行为主义政治学并没有大量运用定量研究,也没有从根本上摒弃价值研究。     

正烯烃沸点与其分子结构之间定量关系的研究

本文根据分子结构的特点，借助图论探讨了正烯烃的沸点与分子结构的关系，提出了一个具有一定结构基础的定量关系。对４０种正烯烃的计算结果表明，沸点计算值都接近实验值，平均误差仅０．０５４％。     

专书复音词研究的回顾与展望

专书复音词研究可分为四个阶段:萌芽阶段、理论探讨阶段、兴盛阶段和统计方法的新阶段。目前专书复音词研究已取得一定成就,但还存在标准不一、范围不一、方法不够科学等问题,所以运用这些成果中的数据时要小心。当然,运用一定的解决方法还是可以把这些数据综合起来反映汉语构词法发展的概况的。     

A Quantitative Assessment of the Risks from Illegally Imported Meat Contaminated with Foot and Mouth Disease Virus to Great Britain

Foot and mouth disease (FMD) is considered by many as the most important animal disease in the world. FMD is highly contagious and outbreaks incur significant costs as affected countries are severely limited in their ability to trade. A number of trade commodities may be contaminated with FMD virus (FMDV) including animal products, for example, meat. As a member of the European Union, Great Britain (GB) has put in place a number of regulations to prevent the importation of pathogens in imported meat products. However, the illegal importation of meat provides a route by which safety controls may be circumvented and meat from FMD affected areas may be imported. This study assesses the FMD infection risk posed to the livestock population of GB from the illegal importation of meat, and estimates the major contributors to this overall risk, through the development of a quantitative risk assessment model. From model results, the total amount of illegal meat entering GB each year is estimated on average to be 11,875 tonnes. with 90% certainty that this is between 4,398 and 28,626 tonnes per year; of which between 64.5 and 565 kg are contaminated with FMDV. This flow of illegal meat results in an estimate of a frequency of FMD infection in GB livestock of 0.015 cases of infected animals per year, with 90% certainty it is between 0.0017 and 0.053. Imports from the region Near and Middle East account for 47% of this risk, and 68% of the risk is attributed to bone-in and dried de-boned products.     

1996—2005：中国都市报10年研究实证分析

在都市报第一个10年结束之时,本研究以《中国期刊全文数据库》收录的1996—2005年间有关都市报研究的论文为数据样本,通过定量统计和主题整理,从研究主题、个案分析、作者类别等方面对国内10年间都市报学术研究全貌进行实证分析。10年来都市报理论研究取得较大发展,水准不断提高,但同时也存在一些明显的问题:对新闻人才的研究重视不够,学术研究前瞻性不足,缺乏主动性和自觉意识等。     

Quantitative Estimates of Risk for Noncancer Endpoints

While quantitative estimates of risk have been a standard practice in cancer risk assessment for many years, no similar practice is evident in noncancer risk assessment. We use two recent examples involving methylmercury and arsenic to illustrate the negative impact of this discrepancy on risk communication and cost-benefit analysis. We argue for a more balanced treatment of cancer and noncancer risks and suggest an approach for reaching this goal.
