Maternity and child health care in urban China

In China the effort to develop maternal and child health (MCH) care has been ongoing. Initially, attention was directed primarily to promulgating a modern method of delivery in an effort neonatal tetanus and puerperal fever. The next stage was the systematic management of MCH care. Pregnant women and puerperants were given a series of checkups and guidance from conception until the 42nd day after delivery. The purpose was to prevent and treat complications. In some cities, perinatal care has developed to the point of health care management of the health of both mother and child. This extensive health care system includes preconception and pregnancy care, puerperant care, and neonatal care. Premarital checks have become the rule in the urban areas. MCH care organizations at the grassroots level and community health workers take responsibility for advising newly married couples about health care. In addition, some medical colleges and their affiliated hospitals provide consultation services for these couples. The Shanghai Railway Medical College uses a computer to make projections on multigenic genetic diseases. It provides information on incidence risk of the next generation to help couples make their childbearing decisions. The majority of pregnant women get their 1st prenatal check prior to the 12th week of pregnancy, followed by 9 re-examinations to screen out high risk factors. Difficult labor, infections, obstetric trauma, postpartum hemorrhage, and fetal distress are prevented at childbirth. Newborns are scored with Apgar comments; those with low marks are specially protected. In some cities, an investigation system has been established to deal with perinatal deaths. Perinatal care is managed at 3 levels: community MCH centers and MCH departments of hospitals, clinics, and industrial enterprises form the 1st level of care; MCH centers of city districts and hospitals at the district level make up the 2nd level of care; and MCH institutes or hospitals at provincial or city levels, hospitals attached to medical colleges, and hospitals under government ministries form the 3rd level of care.

产品类型差异下的消费者渠道偏好异质性 ———基于调节定向理论∗

产品类别是消费者行为研究的重要变量,消费者渠道偏好往往因为产品类别的不同而迥异。 消费者购买不同类型产品时的渠道偏好有何不同? 基于调节定向理论,引入产品实用享乐性与风险性,探 究消费者购买不同类型产品时的消费者渠道偏好差异。 围绕产品的实用享乐性、风险性与消费者渠道偏好 的调节定向匹配提出了 4 个假设,运用实验法采集数据,通过对样本数据的多项 Logistic 分析,对假设进行 了检验,并提出企业顾客管理建议,以期为企业根据产品类型区别建设渠道提供决策支持。     

教师社会幸福感现状及提升策略--基于全国33590名中小学教师的调查与分析

教师社会幸福感影响教师总体的职业幸福感。为揭示教师社会幸福感的整体状况及其在领导关系、同事关系、师生关系、家校关系、社会声誉等维度上的具体表现,在全国范围内,对东部、中部、西部、东北等4个地区的33590名中小学教师的社会幸福感现状进行问卷调查。调查结果显示:教师社会幸福感总体水平较高,但在性别、地区、教龄等方面存在差异。要进一步增强教师社会幸福感,应着力改善教师与领导关系和师生关系;满足教师的物质需求和发展需求,切实提升教师社会声誉;考虑个体差异,制定具有针对性的教师社会幸福感提升策略;改进教师职前教育和在职教育,提升教师获得社会幸福感的能力。
