创业者的压力、情绪与创业努力——基于体验抽样法的实证研究

利用体验抽样法对78位创业者的压力、情绪和创业努力进行了持续一个月的跟踪调查。在使用多层线性模型分析软件对数据进行分析后发现:创业者感受到的时间压力会促进创业者做出更多努力,而创业者感受到的情境压力会减少创业者的努力;创业者感受到的压力不仅会带来消极情绪,而且会激发其积极情绪;创业者的积极情绪和消极情绪在创业者感受到的压力与创业努力之间存在部分中介作用。     

我国服务业省级集聚的空间效应研究——基于横截面数据的空间计量分析

本文对2014年我国31个省级行政区域服务业集聚进行研究,采用莫兰指数对服务业集聚水平进行分析,并对各地区的集聚模式进行分类,通过空间滞后模型研究各变量对服务业集聚的影响。研究表明:我国服务业在各区域存在显著的空间集聚效应,东部地区大多属于高值—高值集聚或者高值—低值集聚,西部地区多为低值—低值集聚或低值—高值集聚模式;服务业固定资产投资、城镇化率、高新技术产业、批发零售业、交通运输业、金融业、房地产业对服务业集聚均存在显著的促进作用。基于上述分析,本文提出了相应的对策建议。

1980—2018年中国苹果生产及其需水量时空演变特征研究

[目的]中国是世界苹果生产和消费第一大国,研究我国苹果生产及其需水量时空演变特征,对苹果产业发展、生产水资源管理和政策制定具有重要意义。然而,针对全国苹果种植及其生产的资源环境压力研究较少。[方法]文章基于1980—2018年苹果生产和单位水足迹数据,从全国、省域和苹果主产区3个视角,深入探究苹果生产及需水量的时空演变特征。[结果]（1）中国苹果生产发展经历了稳定发展、快速增长、迅速下降、缓慢增长和略有下降5个阶段,全国产量呈不断增加趋势,且苹果生产得到了优化。（2）中国苹果生产的单位水足迹呈下降趋势,但苹果生产需水量呈先增加后减少的“倒U型”趋势。（3）我国五大苹果产区的苹果种植面积、单产和产量发生了一定变化,且呈现出不同的变化趋势。黄土高原产区已经替代渤海湾产区成为我国苹果生产最重要的区域,尤其是陕西省,其种植面积和产量均居首位;近年来,西南冷凉高地产区和特色产区种植面积不断扩大。（4）我国各地的苹果生产需水量空间差异很大,其中山东、河北、辽宁、陕西、甘肃、山西和河南相对较大。尽管渤海湾产区苹果生产需水量仍然最大,但比重明显下降,而黄土高原产区需水量不断增加,已占全国总生产需水量的...     

新农村建设背景下农民科技培训实证研究——基于宁波的调查研究

农民是农业生产的主体,也是农业科学技术转化的重要载体,同时也是建设社会主义新农村的主力军,农民科技文化素质的高低直接决定着现代农业发展的水平,关乎着新农村建设的成败。为了将农民科技培训工作推向新阶段,我们采用问卷调查和个案访谈的方式对宁波市农民科技培训进行调查,深入分析其现状、效果、问题,在此基础上提出完善农民科技培训的政策建议。     

Effect of marriage registration on fertility and intrahousehold distribution in Thailand

Research has shown that changes in the marriage and family laws generally affect the formation, welfare distribution, and dissolution of marriage. However, little is known about the effects of constituting state-sanctioned marriage as opposed to informal marriage, where these laws do not fully apply. The present paper studied the effects of formal marriage registration on fertility outcomes and intrahousehold distribution among married couples in Thailand. Using data from the 1993 Survey for the Status of Women and Fertility in Thailand (SWAFT), it was found that marriage registration increases the number of children in a family and enhances women's contribution to and control of household finances. These results suggest that formal marriage registration promotes spousal cooperation and increases the welfare of women, supporting recent policy efforts in many developing countries in the development and expansion of vital registration systems.     

Examining the heterogeneity of treatment patterns in attention deficit hyperactivity disorder among children and adolescents in the Texas Medicaid population: modeling suboptimal treatment response

Objectives: To examine suboptimal responses (SR) in attention deficit hyperactivity disorder (ADHD) among pediatric patients in the Texas Medicaid program receiving osmotic-release oral system methylphenidate (OROS-MPH) or lisdexamfetamine (LDX) and apply an SR prediction model to identify patients most likely to experience an SR to either OROS-MPH or LDX therapies.

Methods: A retrospective cohort study was conducted using Texas Medicaid claims data of ADHD children and adolescents (6–17?years of age) initiating OROS-MPH or LDX. Primary SR endpoints were drug discontinuation, switching, and augmentation 12-months post-ADHD drug initiation. Logistic regression models were developed to predict SR to OROS-MPH and LDX in 1:1 matched groups of children and adolescent cohorts.

Results: A total of 3,633 children and 1,611 adolescents were matched for each cohort. SR was observed among more children (76.4% vs 72.3%; p?p?=?0.002) initiating OROS-MPH compared to LDX. Patient sub-groups with the highest predicted risk of OROS-MPH SR experienced significantly lower observed SR rates (p?Conclusions: This study demonstrated how a personalized medicine approach using administrative claims data can be used to identify sub-groups of child and adolescent ADHD patients with different risks for suboptimal response with OROS-MPH or LDX in a Medicaid population.
