The effects of teenage childbearing on long-term health in the US: a twin-fixed-effects approach

This paper explores the effect of teenage childbearing on long-term health outcomes and behaviors of mothers using the Midlife Development in the US dataset. Within-family estimations, using samples of siblings, and twin pairs, are employed to overcome the bias generated by unobserved family background and genetic traits. The results suggest no significant effects on health outcomes, and modest effects on health behaviors, including exercise and preventive care. However, accounting for life-cycle effects demonstrates that teenage childbearing has significant effects on both health outcomes and behaviors early in life, but very few significant effects later in life. Moreover, teenage childbearing has a particularly acute effect among minorities. Finally, this paper provides evidence that the effects operate through reduced income and labor force participation, and matching with a lower “quality” spouse.     

The FARSEEING real-world fall repository: a large-scale collaborative database to collect and share sensor signals from real-world falls

Background

Real-world fall events objectively measured by body-worn sensors can improve the understanding of fall events in older people. However, these events are rare and hence challenging to capture. Therefore, the FARSEEING (FAll Repository for the design of Smart and sElf-adaptive Environments prolonging Independent livinG) consortium and associated partners started to build up a meta-database of real-world falls.

Results

Between January 2012 and December 2015 more than 300 real-world fall events have been recorded. This is currently the largest collection of real-world fall data recorded with inertial sensors. A signal processing and fall verification procedure has been developed and applied to the data. Since the end of 2015, 208 verified real-world fall events are available for analyses. The fall events have been recorded within several studies, with different methods, and in different populations. All sensor signals include at least accelerometer measurements and 58 % additionally include gyroscope and magnetometer measurements. The collection of data is ongoing and open to further partners contributing with fall signals. The FARSEEING consortium also aims to share the collected real-world falls data with other researchers on request.

Conclusions

The FARSEEING meta-database will help to improve the understanding of falls and enable new approaches in fall risk assessment, fall prevention, and fall detection in both aging and disease.

印度东北与中国西南的民族志诗歌

印度东北与中国西南在地域上山水相连,相互之间的文化交流是非常密切的。这个区域里居住着众多的民族或族群,他们的文化相似性和可比性是很明显的。从跨国的视角来探寻文化互动或文化个性,这是一个理想的地域。这些不同民族或族群身份的诗人写作的民族志诗歌是探寻各自文化共性和个性的较好途径：虽然诗歌创作过程中采用不同的语言,印度东北的土著诗人通常用英语写作,中国西南少数民族诗人经常用汉语写作,但是这些诗人都受到了近代西方现代主义诗歌潮流的影响。同时,这些诗人的诗歌也受到了当下全球化的影响,比如本民族传统文化与文化教育现代化、全球生态环境日益恶化等等冲突的影响。因为受到了相似的影响,这个区域内的民族志诗歌的风格和肌理是可以比较的;诗歌的主题和内容也是可以展开对比研究的。     

文化融合与民族大学生国家认同教育

文化融合是一种客观的历史现象,也是现今的一种社会存在状态;是民族关系的重要内容,也是文化得以发展的重要途径。国家的概念则是近现代才从西方国家传入的新鲜产物,是生活在其地域范围内的人们对其所在国家的认识、评价与情感,主要表现于国家政治共同体和结构层面以及共同的中华民族的精神层面的认同。国家认同于国家本身、于个人都具有非常重要的意义,其中少数民族的国家认同问题显得尤为迫切。而国家认同教育是国家认同构建中的重要内容和方式。学校教育是建立国家认同的有效途径。我国的各民族的文化融合是少数民族国家认同教育的前提与基础、有力保障、表现形式,也是少数民族大学生国家认同教育的高级目标,具有重要的意义与深远的影响。我国也从中国的实际情况出发,并吸收了中国历来坚持＂和而不同＂处理民族关系的宝贵经验与优秀传统,制定出了相应的民族政策,坚定地保障民族文化融合,加强少数民族的国家认同教育,促进国家的稳定与团结。     

宗教事务依法管理的路径及基础——以四川藏区依法治理为视角

Under the situation that traditional beliefs have remained basically unchanged while the social economy has developed and population mobility has increased, with the trend of an in-creasing diversity in beliefs, and an increasing number of religious followers and temples, the management of religious affairs has become more difficult. In ethnic areas, the speed of moderniza-tion has accelerated, ethnic interactions are fre-quent, and the beneficial conflict or cultural con-flict among various ethnic groups has become nor-mal; the impact of modernity, ways of life, the value and ideals of the temples’ traditional culture and educational model brings new social pressure for the monks who are adapting to modernization, and making a leap in development while safeguard-ing traditional rituals, culture, religious education and development. The number of criminal cases involving monks has increased, which brings a strong negative influence to the religious followers in Tibetan areas. All these factors are directly in-fluencing the stability and harmonious development of the Tibetan areas. As the second-largest Tibetan area, the geo-graphical location of Sichuan’s Tibetan areas is u-nique. In ancient times, the policy of “keeping the Tibetan areas stable means keeping Kham sta-ble at first” had been an important measure for the central government to manage all of the Tibetan ar-eas. From the Qing dynasty to the present times, it still has a practical use, and even has special val-ue in the process of safeguarding the “long-term stability of Sichuan”, especially when the people have but a hazy understanding of the relationship between the freedom of faith and managing reli-gious affairs according to the law in Tibetan areas, and one needs to have a legal response to it. Hence, “keeping Kham stable” needs to depend on the law, and legal means should be taken to safeguard the harmony and stability of the Tibetan areas in Sichuan. Management of the religious affairs according to the law is an inevitable requirement for China to promote the goal of ruling the country by law, com-prehensively deepen reform, and promote the mod-ernization of the country’s governance system and capability. Based on an active response to the guidance principle of strengthening the manage-ment of religious affairs according to the law pro-posed by the Central Government, and the Sichuan Provincial Government, we should standardize reli-gious activities and affairs, insist on a combination of legal management and policy guidance, adopt various measures, search for a practicable path to realize the significant goal of managing the religious affairs according to the law in Tibetan areas of Si-chuan. This article proposes some methods of man-aging the religious affairs according to the law as follows:1 ) To insist on the CPC’s leadership in reli-gious work and management of religious affairs;2 ) to actively and reliably promote the systematic con-
struction of the legalization of religious affairs;3 ) to insist on the combination of legal management and policy guidance;4 ) to encourage the public to manage religious affairs according to law; 5 ) to standardize the scale and number of monks by u-sing new methods of management;6 ) to strengthen the role of the “four troops” ( Party and Govern-ment leading cadres,ethnic religious work cadres, ethnic minority cadres and talents, and religious believers ) , especially religious believers; 7 ) to make full use of the regulatory framework of the Buddhist community; 8 ) to create conditions for those monks who wish to return to secular life;9 ) to distinguish the boundary between normal and il-legal religious activities, between folk custom and extreme religious concepts; 10 ) to identify and distinguish between “monks and lay people”, and“ordinary cases and religious cases”. At present, there are four foundations for managing religious affairs according to the law:1 ) the idea that freedom of faith is not only one’s right, but also one’s duty has gradually enjoyed popular support;2 ) there is a good policy base for managing religious affairs according to the law;3 ) there is a relatively strong theoretical basis for managing religious affairs according to the law;4 ) there exists good legal support for managing reli-gious affairs according to the law.     

民族的血缘性及其在当代中国的演化

在中国历史和现实中,谈民族无论如何是和血缘分不开的.中国人有认祖归宗的传统,实质上就是一种血缘认同.基于此,我们对民族概念的界定,也应该从实际出发,回归到中国社会一般理解和运用的那种含义,而不必去跟随外来话语莫衷一是.民族具有血缘性,除了一部分真实之外,更大部分是出于认同需要的“血缘拟制”.民族过程的基本倾向之一是民族的血缘性不断下降,而反映这种变化的直观表现就是族际通婚.改革开放是中国各民族交往交流交融最为深刻的时期,也是中国各民族的血缘性得到最为深刻改造的时期.无论是对照以往的调查资料还是经验观察,都可知当前我国族际婚姻的数量在增多,范围在扩大.族际通婚的增加淡化了各民族自身的血缘性,却增添了各民族之间血缘的联通性.各民族通过族际通婚将自己的血缘扩散到其他民族的过程,也就是中华各民族之间的血缘联系得到更为巩固的过程.     

基于生态足迹模型的川西北高原地区可持续发展的耦合路径分析

在2010年国务院发布的《全国主体功能规划》中,川西北高原地区被确定为限制开发区和禁止开发区,成为国家重要的生态功能区之一。由此,在“生态保护”和“限制开发”的前提下,如何推进该地区经济社会的可持续发展,是各级地方党委政府必须面对和研究并解决好的重要问题之一。为此,本文以川西北重点生态功能区——红原县为例,运用生态足迹模型,对该区域自然资源的利用情况和自然生态系统的供给能力进行剖析,进一步分析了该区域的可持续发展状况,找出可持续发展中存在的主要问题和构成要素。在此基础上,以生态系统和经济发展系统相互耦合为视角,提出川西北高原地区可持续发展的耦合路径及对策建议。
