我国小家电产品的国际竞争力分析

本文通过对我国小家电在国际市场上的占有率以及主要国家和地区小家电的显性比较优势指数(RCA)和贸易专门化指数(TSC)的分析,发现我国小家电在国际市场上的竞争优势明显高于其他国家。我国小家电的竞争优势源于其低成本和低价格。但从长远角度考虑,我国的小家电应该在技术研发、市场拓展方面做更多的努力。     

QM在SAP R/3系统中的运行原理

SAP公司,在中国企业管理界来说绝对不会陌生,SAP可以说是ERP的代名词。SAP公司的R/3系统凭借其自身系统的完美性、极高的成功率,令无数企业爱不释手,但其不匪的身价却又使企业有可望而不可求之感。SAPR/3系统是由SD模块、FI模块、CO模块等组成的企业资源管理系统,且每一个模块都在系统中发挥极其重要的作用。     

顺从还是懈怠？中注协约谈与执业质量检查的叠加监管压力研究

基于压力理论和制度理论,以2014—2018年沪深A股非金融类上市公司为研究对象,探究中注协约谈与执业质量检查的叠加监管压力对审计质量的影响。实证结果表明,在中注协约谈与执业质量检查的叠加监管压力下,审计师显著提升了审计质量。进一步研究发现,行业叠加监管压力对审计质量的提升作用只在当面约谈、签字注册会计师同性别、签字注册会计师平均执业年限较长、签字注册会计师年平均客户数量较少时才明显;行业叠加监管压力与法律监管压力之间存在着替代作用;在面对行业叠加监管压力时,审计师也收取了一定的溢价。研究结论能够明晰审计师面临行业叠加监管压力时的行为表现,也对证券审计市场行业自律性监管具有借鉴意义。

Cervical cancer prevention in Morocco: a model-based cost-effectiveness analysis

Abstract

Objective: Cervical cancer is a huge public health issue in Morocco which represents the second most frequent and fatal cancer among women. Countries that have not yet introduced the HPV vaccine could benefit greatly, but before implementation it is necessary to perform country-specific economic assessments that include current screening practices.

Methods: A Markov model was developed to simulate the natural history of HPV and cervical cancer so as to calculate the long-term health benefits and costs of HPV vaccination and current screening by visual inspection with acetic acid (VIA). Starting from a previous transition probability matrix used for a model from Spain, the present model was calibrated to cervical cancer incidence from Morocco. Cost survey data was used to estimate the cost of screening and clinical procedures from the public healthcare perspective. Incremental cost-effectiveness ratios were calculated as 2018US$ per additional year of life saved (YLS) and both costs and health outcomes were discounted at 3%.

Results: The expected reduction in lifetime risk of cervical cancer for current screening would be 14% at a cost of US$551/YLS compared with no intervention, assuming VIA every 3 years in women aged 30–49 at 10% coverage. HPV vaccination of pre-adolescent girls at 70% coverage would reduce the lifetime risk of cervical cancer by 62% at a cost of US$1,150/YLS, compared with no intervention. When implementing HPV vaccination in combination with current screening, vaccination would be dominated, and the combined strategy would provide a 69% reduction at a cost of US$2,843/YLS, compared with screening alone. Current screening would be dominated by vaccination when screening coverage is higher than 15%, whereas the combined strategy rapidly exceeds US$4,000/YLS.

Conclusions: HPV vaccination could be highly effective and cost-effective in Morocco. Current screening would be good value for money compared with no intervention, but scaling-up screening coverage would make it inefficient compared with vaccination.
