Electronic Resource Management Systems (ERMS) Review

This column provides a status update of electronic resource management systems (ERMS) in addition to librarian comments concerning benefits, challenges and wish lists for ERM tools. Nine company/organization profiles are provided based on survey responses: the CUFTS ERM (an open source ERMS developed by Simon Frasier University), EBSCO’s ERM Essentials?, Ex Libris’ Verde, Colorado Alliance’s Gold Rush, HARRASSOWITZ’s HERMIS, Innovative ERM, Serials Solutions 360 Resource Manager, SwetsWise eSource Manager and TDNet Open ERAM. Each profile describes availability, development, use of standards, compatibility, functionality and distinguishing features.     

南非物流成本统计方法研究

宏观物流成本是评价一个国家经济发展质量的重要指标,客观、科学地统计宏观物流成本具有非常重要的意义。在系统地介绍了南非物流成本统计模型中的分解与合计统计方法的基础上,着重介绍了合计方法。合计方法是按每一种产品的生产量分别进行统计,比较符合物流运作的实际情况,可以为中国物流成本统计方法的改进提供有益的参考和借鉴。     

Geographic distribution of cardiovascular comorbidities in South Africa: a national cross-sectional analysis

Objectives: We sought to estimate the spatial coexistence of hypertension, coronary heart disease (CHD), stroke and hypercholesterolaemia in South Africa. Design: Cross-sectional. Setting: Sub-Saharan Africa and South Africa. Participants: Data were from 13,827 adults (mean±SD age 39±18 years, 58.4% women) interviewed in the 1998 South African Health and Demographic Survey. Interventions: N/A. Primary and secondary outcome measures: We used multivariate spatial disease models to estimate district-level shared and disease-specific spatial risk components, controlling for known individual risk factors. Results: In univariate analysis, observed prevalence of hypertension and CHD is was high in the south-western parts, and low in the north east. Stroke and high blood cholesterol prevalence appeared to be evenly distributed across the country. In multivariate analysis (adjusting for age, gender, ethnicity, education, urban-dwelling, smoking, alcohol consumption and obesity), hypertension and stroke prevalence were highly concentrated in the south-western parts, whilst CHD and hypercholesterolaemia were highly prevalent in central and top north-eastern corridor, respectively. The shared component, which we took to represent nutrition and other lifestyle factors not accounted for in the model, had a larger effect on cardiovascular disease prevalence in the south-western areas of the country. It appeared to have greater effect on hypertension and CHD. Conclusion: This study suggests a clear geographic distribution of cardiovascular disease in South Africa, driven possibly by shared lifestyle behaviours. These findings might be useful for public health resource allocation in low-income settings.     

Dealing with noncompliance and missing outcomes in a randomized trial using Bayesian technology: Prevention of perinatal sepsis clinical trial,Soweto, South Africa

The success of interventions designed to address important issues in social and medical science is best addressed by randomized experiments. With human beings there are often complications, however, such as noncompliance and missing data. Such complications are often addressed by statistically invalid methods of analysis, in particular, intention-to-treat and per-protocol analyses. Here we address these two complications using a statistically valid approach based on principal stratification with a fully Bayesian analysis. This analysis is applied to a randomized trial of a potentially important intervention designed to reduce the transmission of bacterial colonization between mothers and their infants through vaginal delivery in South Africa: the Prevention of Perinatal Sepsis (PoPs).     

《未成年人保护法(修订草案)》述评与完善

未成年人保护法修订草案积极回应了当前面临的未成年人法律困境和现实诉求,提出和细化了许多具体举措,尤其是新增了未成年人最大利益原则,确立了国家监护制度,体现了重大的进步。在立法关系上,无论是与预防未成年人犯罪法草案,还是与现行的其他涉及未成年保护的相关法律,未保法草案均与之存在着不协调问题。未保法草案的修法思路亟待从“理想化的统领和难以操作的补漏”转向务实性的“重点明晰和问题导向”,亦即未成年人保护法的“福利法化”并呼应预防未成年人犯罪法的“少年法化”。未保法草案的体例布局未能充分体现立法本意和修法初衷,在概念厘清、文本形式、涵盖内容与表达逻辑上均需要进一步改进和完善。
