提高农民工收入是转型期我国经济社会工作的重要内容。文章使用全国农村固定观察点2011-2014年数据,采取PSM-DID等识别方法,在生命周期的视角下研究了基础教育和职业培训对于提升农民工外出收入的异质性影响。随后从就业方式、从事行业和从业地点等维度进行了差异性甄别和机制性解释,并就两者如何影响收入不平等问题进行了讨论。研究发现:(1)由于现阶段农民工被锁定在低技能行业,相较于基础教育,职业培训对农民工外出收入产生了更大的正向影响,这不仅体现在短期的"即时效应",也表现为基于生命周期的"长期效应"。(2)这些影响在不同外出就业类型、从事行业以及从业地点均具有异质性。(3)基础教育和职业培训不仅能够提高农民工的收入,还能降低农村地区的收入不平等,并且职业培训的效用更大。文章对于通过提升人力资本增加农民工收入、缩小收入差距具有一定的政策启示。

BackgroundThe increasing global cancer incidence corresponds to serious health impact in countries worldwide. Knowledge-powered health system in different languages would enhance clinicians' healthcare practice, patients' health management and public health literacy. High-quality corpus containing cancer information is the necessary foundation of cancer education. Massive non-structural information resources exist in clinical narratives, electronic health records (EHR) etc. They can only be used for training AI models after being transformed into structured corpus. However, the scarcity of multilingual cancer corpus limits the intelligent processing, such as machine translation in medical scenarios. Thus, we created the cancer specific cross-lingual corpus and open it to the public for academic *** to build an English-Chinese cancer parallel corpus, we developed a workflow of seven steps including data retrieval, data parsing, data processing, corpus implementation, assessment verification, corpus release, and application. We applied the workflow to a cross-lingual, comprehensive and authoritative cancer information resource, PDQ (Physician Data Query). We constructed, validated and released the parallel corpus named as ECCParaCorp, made it openly accessible *** proposed English-Chinese Cancer Parallel Corpus (ECCParaCorp) consists of 6685 aligned text pairs in Xml, Excel, Csv format, containing 5190 sentence pairs, 1083 phrase pairs and 412 word pairs, which involved information of 6 cancers including breast cancer, liver cancer, lung cancer, esophageal cancer, colorectal cancer, and stomach cancer, and 3 cancer themes containing cancer prevention, screening, and treatment. All data in the parallel corpus are online, available for users to browse and download (http://***/ECCParaCorp/).ConclusionsECCParaCorp is a parallel corpus focused on cancer in a cross-lingual form, which is openly accessible.

Objectives Milletia speciosa Champ (MS), a traditional Chinese medicine, has the abilities of antistress, antifatigue, anti-oxidation and so on. In our previous study, MS was found to antidepression while the underlying mechanism of which needs further elucidation. Methods Here, a proton nuclear magnetic resonance (H-1-NMR)-based metabonomics combined network pharmacology research approach was performed to investigate the antidepressive mechanism of MS act on mouse with chronic unpredictable mild stress-induced depression. Key findings Results showed that MS could alleviate the ethology of depression (including sucrose preference degree, crossing lattice numbers and stand-up times) and disordered biochemical parameters (5-hydroxytryptamine, norepinephrine and brain-derived neurotrophic factor). Metabonomics study and network pharmacology analysis showed that MS might improve depression through synergistically regulating five targets including Maoa, Maob, Ache, Ido1 and Comt, and three metabolic pathways such as tryptophan metabolism, synthesis of neurotransmitter and phospholipid metabolism. Conclusions This study for the first time preliminary clarified the potential antidepressive mechanism of MS and provided theoretical basis for developing MS into novel effective antidepressant.

产权和生产率的关系一直是发展经济学研究的热点,而中国新一轮的农地确权为探究两者的关系提供了一个良好的外生自然实验。本文利用浙江大学中国家庭大数据库(CFD)2015年和2017年的数据,通过面板固定效应模型,研究了农地确权政策是否、多大程度上以及如何影响农地生产率。研究结论显示,农地确权会显著提高农地生产率(3.7%),且其效应存在时间异质性。对确权1年以内的农户没有影响,但能显著提高确权1年以上农户的农地生产率(5%)。进一步的机制探究发现,稳定的产权能增加农户对农地的长期投资,同时加速农户的农地流转行为,进而提升农地生产率。

For the screening of novel toxic-element-free and biocompatible electrochemiluminophores, electrochemiluminescence (ECL) of multinary nanocrystals (NCs) was investigated for the first time with Zn Ag In S (ZAIS) NCs as model. Aqueous soluble ZAIS NCs could bring out efficient reductive-oxidation ECL with tri-n-propylamine as coreactant, while coating the ZAIS NCs with a ZnS shell could reduce the surface defects of ZAIS NCs, and enable 6.7-fold enhanced ECL of ZAIS/ZnS NCs as compared to ZAIS NCs. ECL of ZAIS/ZnS NCs was about 4.2-fold that of ternary CuInS2/ZnS NCs, spectrally similar to that of Ru(bpy)(3)(2+) with maximum emission around 605 nm, and favorable for less electrochemical interference with a lowered triggering potential (similar to 0.95 V) than that of Ru(bpy)(3)(2+). An ultrasensitive ECL microRNA sensor was fabricated with ZAIS/ZnS NCs as tags, which could sensitively and selectively determine microRNA-141 with a wide linearity range from 0.1 fmol/L to 20 pmol/L and a low limit of detection at 50 amol/L (S/N = 3). Multinary NCs might provide a promising alternative to the traditional binary NCs for both electrochemiluminophore screening and NC ECL modulating.

Background: Closed-loop electronic medication management systems are effective measures for preventing medication errors (MEs). However, there is limited evidence supporting this, and few studies have evaluated the long-term effects of these systems on safe medication. Objective: To evaluate the long-term effects of implementing a closed-loop medication order executive system on the safe clinical use of medications. Design: A quasi-experimental design. Method: Data from 2017 to 2023 were extracted and retrospectively analyzed. The primary outcome indicator was the ME rate. Secondary outcome indicators were the accuracy of order verification and patient identification and the implementation rate of fresh medicine dispensing. The autoregressive integrated moving average (ARIMA) model in time-series analysis was used to evaluate the level and trend changes in ME rates using SPSS 25.0 before and after system implementation. Root cause analysis and descriptive statistics were used to assess changes in types, stages, and causes of ME rates. The independent samples t-test was used to analyze secondary outcomes. Results: Overall, 295 MEs were reported with a mean of 0.26 +/- 0.26 ME rates per month during 2017-2023. The ARIMA model showed a decrease in the average level of ME rates after system implementation, with no statistically significant decrease in the long term, and a significant drop in the ME rate in the short and medium term (p < 0.01). Nurses' administration accounted for more than 60% of errors post-implementation, and lack of communication was a prominent factor. The accuracy of order verification and patient identification and the implementation rate of fresh medicine dispensing all increased after implementation. Conclusion: Adopting a closed-loop executive system is beneficial for ensuring patient medication safety, but a single integrated system does not completely eliminate MEs. Optimizing system functionalities and applying structured handoff tools are r

As translated education resource plays an important role in healthcare providers' training and medical knowledge dissemination, we proposed a method to manage cross-lingual education resources with the goal of facilitating the medical education and physician training. We created an English Chinese cancer knowledge base including bilingual description on cancer diagnosis, prevention, screening, treatments, etc. We developed a workflow to create the bilingual corpus, and applied it to six cancer monographs in PDQ (Physician Data Query).

小农户如何与现代农业发展有机衔接是党的十九大提出的重要科学问题,其中小农户如何对接大农机是其中一个重要方面。首先建立了一个旨在解释农机在中国成为俱乐部商品的理论模型,随后利用2011-2014年全国农村固定观察点数据研究非农就业对农户农机使用行为的影响。随机效应面板Tobit模型的实证结果表明:无论是外地就业,还是本地非农就业,均对农户的农机直接投资产生负向影响,但增加了农户对农机服务的利用。从总体上来看,非农就业促进了农业机械化水平的提高。采用排除异常值干扰的面板Logit模型,使用解释变量的滞后项回归和考虑内生性的PSM-DID等一系列检验验证了基本结论的稳健性。在土地市场和农村劳动力市场缺失的双重约束下,农机化的发展重点应落脚于提升适合跨区作业的高端农机的供给能力,进一步发展农机服务市场。
