The new treatment mode research of hepatitis B based on ant colony algorithm

Hepatitis B (HB) is a deadly disease that has a severe impact on infected individuals. In China, not only are the incidence and infection rates of HB very high, but also many HB patients suffer from mental illness associated with anxiety and fear because of HB-associated symptoms. This exacerbates the patients’ condition, potentially increasing the risk of mortality. In this paper, we propose a new treatment mode to improve the therapeutic efficiency and patients’ satisfaction with their healthcare. In a single process of this new treatment, several patients with similar disease symptoms are treated by one doctor at the same time. This new treatment mode can not only relieve the anxiety and fear of HB patients, and improve patients’ cognition rate of HB, but also reduce the HB infection rate, slow down the progression of disease symptoms, and shorten the course. If patients with similar disease symptoms are to be grouped together, there is a need to determine the optimal patient batch combination, which can be solved in the new mode, called patient combined problem (PCP). We also constructed a mathematical model of PCP, and present the ant colony (AC) algorithm and Enhanced AC with a P-3-exchange operator for PCP in the new treatment mode in this paper. We also performed an experiment that showed that our proposed algorithms are very fast and effective for solving this problem.

     

“坚守”还是“离开”——基于扎根理论的公办园非编教师留任意愿影响机制研究

分析影响非编教师留任意愿的深层次原因发现,教师的权益保障直接影响公办园非编教师的留任意愿。留任期待值与留任相对成本共同反映了留任效价,并且既直接影响留任意愿,也调节了教师权益保障与留任意愿之间的关系;自我认知、重要环境、重要他人三个因素构成了留任的内外情境,既以留任效价间接作用于留任意愿,也成功调节了教师权益保障与留任意愿之间的关系。基于公办园非编教师留任意愿影响因素模型,应重视公办园非编教师的教师权益保障,落实好其薪资福利待遇;优化公办园非编教师的管理方式,减轻其对留任成本的担忧;完善非编幼儿教师招考录用机制,增强其外部留任情境的稳定性;求职者也应做好职前自我评估,增强自身内部留任情境的坚定性。     

政治仪式铸牢中华民族共同体意识的四个维度

铸牢中华民族共同体意识的核心,是引导各族人民牢固树立“休戚与共、荣辱与共、生死与共、命运与共”的共同体理念。政治仪式作为国家政治社会化途径之一,本身就是以国家为单元的共同体凝聚机制。在铸牢中华民族共同体意识的全过程中,政治仪式作为重要形式与展开路径,以其特有的时间性、空间性、公共性、共同性特征,推动了在中华民族主权国家内以“中华民族共同体”为中心的记忆刻写、在场体悟、价值引导、文化信仰、情感认同、行为规范等叙事实践,多维多层次彰显中华民族共同体意识的共同性内核。在以铸牢中华民族共同体意识推动中华民族共同体建设的新时代,需要充分认识政治仪式的政治社会化功能,挖掘其承载的共同性价值,拓展其民族共同体建设途径。     

共同富裕的指标体系构建与应用

本文以新发展阶段共同富裕的理论内涵为指导,从总体富裕、均衡水平、弱势保障三个维度入手,构建了共同富裕的评价指标体系。综合使用省级数据、地级市数据和微观调查数据,运用熵值法对我国24个省份2013至2019年间隔年份的共同富裕水平进行了测度。研究表明：我国各省共同富裕水平自2013年起大幅提升;2019年,浙江、江苏、吉林共同富裕水平列全国前三,河南、广西、广东三省共同富裕水平列全国末位;此外,本文对2019年各二级指标的得分排名进行分析,厘清各地区当前共同富裕的驱动因素和阻碍短板,为各省进一步推动共同富裕指明方向。     

党的群众路线历史演进与经验启示:乡村治理的视角

乡村治理是富于群众性的实践场域,也是考察党的群众路线的重要切口。建党以来,中国共产党始终将群众路线贯彻至引领乡村治理变迁的历史谱系中。一方面,历经探索形成、曲折发展、制度重塑及调适完善四个历史阶段,群众路线的乡土实践已日臻成熟,凝结为深厚党群关系的关键政治资源;另一方面,通过保证内在结构的均衡配置、注重基层党组织的建设水平以及切合社会保存的底蕴特征,群众路线的历史演进也积累了宝贵经验,成为党稳固执政根基的重要路径。在全面建设社会主义现代化强国的新征程上,群众路线仍需因循时代任务与治理环境的变动而灵活调整,切实融入推进国家治理现代化的基础工程中。     

Lifestyle Options and Economic Strategies: Subsistence Activities in the Mississippi Delta1

Abstract "Subsistence" and "informal economy" are contrasted in their utility as sociological concepts and their ability to explain a variety of activities in two rural Mississippi Delta communities. Literature on subsistence stresses that the desired outcome of participation is not an increase in income but the social rewards of participation itself. Two underlying dimensions of participation in these activities are documented through the literature and through a confirmatory factor analysis of empirical data: life-style choice and economic strategy. These were constructed into indexes and examined individually and in combination as dependent variables using regressors at the community, household, and individual levels. Community ties were weakly associated with participation in such activities. Whites and those with higher incomes participated more in lifestyle choice oriented activities. Participation in general was statistically related to households needing less weekly income and being of larger size. Potential connections with persistent rural poverty are discussed.

中国文化的三次转型与中国比较文学源流

本文通过对中国文化史上的三次文化转型期：汉唐时期、近代鸦片战争时期及“五四”新文化运动时期、二十世纪末期的文化形态的考察,剖析了文化发展过程中由单一文化系统造成的自我设限──封闭模式到吸收他种系统之后文化走向解构──沟通──重构的规律,指出文化转型的积极意义与比较文学注重沟通、对话、交流的本质精神是契合的,实质上二者之间是互为前提、互为因果的互动关系。     

中国二板市场应无限期推迟——从海外二板市场的教训看中国开设二板的艰难性

德国、日本、澳大利亚及香港等海外二板市场失败的原因是由于其大幅度降低了公司入市的标准和要求,有其必然性。美国纳斯达克市场尚存的原因是其特性与主板有重叠之处,从超长期看,其是否成功还难以确定。本文指出中国拟创立的二板市场理由、目标与海外二板市场衰败的原因如出一辙;加之中国A股市场股本结构分裂,股价高企,没有做空机制,二板市场贸然推出,不仅本身可能会蹈海外多数二板市场的覆辙,而且可能对主板A股市场形成严重影响,故建议中国二板市场无限期推迟。在主板市场可通过附设一个科技创业分板,并应尽快恢复深圳证券市场新股发行工作。
