燃烧着激情的报告——评镇江市作家的散文创

散文的活力在于贴近人民、反映现实。本文对镇江市三位散文作家的作品作了具体分析 ,指出他们的作品虽然题材不同、风格各异 ,但都将形象、情感与思想交融在一起 ,因而产生出真正的艺术力量     

刍议通俗歌曲及其创作原则

通俗歌曲内容广泛 ,贴近生活 ,深受群众喜爱。同时通俗歌曲中存在着一些思想庸俗、格调不健康、艺术水平低下的东西。我们既不能采取一概肯定任其发展的态度 ,也不能采取全盘否定的办法 ,而应吸收其精华 ,剔除其糟粕 ,注重通俗性和民族性相结合的创作原则 ,以促使它的不断完善与提高     

论贾平凹散文的审美类型

贾平凹散在当代坛具有鲜明的个性特征。为20多年来,他不断扩展散的写作内容,不断追求新的审美样式,表现出广阔的审美视野与选材能力。总括而论,贾平凹的散可以分为五个审美类型：自传类、风情类、世相类、禅思类和化类,每一种类型都相对应地承载着他的身世,他对农乡、市井群类的感悟和对民族与人类化的反思。     

论当代农民题材小说及农民形象演变

农民形象在当代文学中明显占据着重要的位置。就文学史的发展过程而言 ,农民形象的演变 ,甚至可以视作是各个文学段落的形象标志。农民形象的变化不仅体现着社会的现代化程度 ,而且也表现出农民自身作为个体的精神独立和人格解放的时代趋势。农民形象的演变 ,实际上就是中国社会、中国文化精神的发展和演化 ,农民在成长中体现了中国社会历史的崭新面貌和走向。     

论李大钊的新民观

李大钊的前期新民思想在某种程度上是对梁启超新民说的承继和发展,后期（十月革命后）,李大钊开始用唯物史观重新审视国民性改造问题,提出了“物心两面”改造的全新新民途径．但因忽视了生产力这一最终动因,其新民说带有一定的空想色彩．     

党的十六大对非公有制经济理论的创新与突破

中共十六大将发展非公有制经济与全面建设小康社会的现实目标紧密联系起来,突破了将坚持公有制的主体地位与促进非公有制经济发展相对立的传统认识误区,强调各种所有制形式应相互促进,共同发展。同时,十六大还突破传统所有制理论,确认了非公有制经济及新兴社会阶层在现阶段的重要地位和作用。强调通过理顺收入分配关系,保护私人财产及一切合法收入,在政治经济上为其健康发展提供制度保证。     

Estimating Benchmark Exposure for Air Particulate Matter Using Latent Class Models

We performed benchmark exposure (BME) calculations for particulate matter when multiple dichotomous outcome variables are involved using latent class modeling techniques and generated separate results for both the extra risk and additional risk. The use of latent class models in this study is advantageous because it combined several outcomes into just two classes (namely, a high‐risk class and a low‐risk class) and compared these two classes to obtain the BME levels. This novel approach addresses a key problem in risk estimation—namely, the multiple comparisons problem, where separate regression models are fitted for each outcome variable and the reference exposure will rely on the results of the best‐fitting model. Because of the complex nature of the estimation process, the bootstrap approach was used to estimate the reference exposure level, thereby reducing uncertainty in the obtained values. The methodology developed in this article was applied to environmental data by identifying unmeasured class membership (e.g., morbidity vs. no morbidity class) among infants in utero using observed characteristics that included low birth weight, preterm birth, and small for gestational age.     

基于AHP-物元综合评判的“工作执法一网考”考核模型及指标体系研究

警务考核是充分调动民警工作积极性，进一步提高打击犯罪和保障平安能力的重要手段，也是世界性难题。广东省公安厅为破解队伍管理的难题，创造性地提出“工作执法一网考”（下称“一网考”）的理念，建设并在全省推广应用“一网考”系统。本文通过对警务绩效考核中存在的问题进行分析，提出了“一网考”的考核模型，在此基础上建立了考核指标体系。基于层次分析法，对考核指标及权重进行了量化，使考核指标具有科学性、客观性和公正性；应用物元理论，建立物元综合评判数学模型，实现对民警的综合评价。     

Assessment of Interindividual and Geographic Variability in Human Exposure to Fine Particulate Matter in Environmental Tobacco Smoke

Environmental tobacco smoke (ETS) is a major contributor to indoor human exposures to fine particulate matter of 2.5 μm or smaller (PM_2.5). The Stochastic Human Exposure and Dose Simulation for Particulate Matter (SHEDS‐PM) Model developed by the U.S. Environmental Protection Agency estimates distributions of outdoor and indoor PM_2.5 exposure for a specified population based on ambient concentrations and indoor emissions sources. A critical assessment was conducted of the methodology and data used in SHEDS‐PM for estimation of indoor exposure to ETS. For the residential microenvironment, SHEDS uses a mass‐balance approach, which is comparable to best practices. The default inputs in SHEDS‐PM were reviewed and more recent and extensive data sources were identified. Sensitivity analysis was used to determine which inputs should be prioritized for updating. Data regarding the proportion of smokers and “other smokers” and cigarette emission rate were found to be important. SHEDS‐PM does not currently account for in‐vehicle ETS exposure; however, in‐vehicle ETS‐related PM_2.5 levels can exceed those in residential microenvironments by a factor of 10 or more. Therefore, a mass‐balance‐based methodology for estimating in‐vehicle ETS PM_2.5 concentration is evaluated. Recommendations are made regarding updating of input data and algorithms related to ETS exposure in the SHEDS‐PM model. Interindividual variability for ETS exposure was quantified. Geographic variability in ETS exposure was quantified based on the varying prevalence of smokers in five selected locations in the United States.
