Measurement and Analysis of Agricultural Production Efficiency in Taiwan of China Based on Three-stage DEA Model

引用

Asian Agricultural Research 2018年第7期10卷 10-15,18页

作者： mengyuan jiang Chunjie QI College of Economics & Management Huazhong Agricultural University

Agricultural production efficiency in Taiwan of China in 2015 is studied by using three-stage DEA model. The results show that total output value of agriculture,forestry,animal husbandry and fishery is taken as output index,while employees of agriculture,forestry,animal husbandry and fishery,number of tractors,investment in dry land and paddy field are taken as input indexes,which meets " isotropic" condition assumption of model application. Natural disaster,number of workers in agricultural production and marketing class,expenditure on farmland water conservancy are not favorable for the promotion of agricultural production efficiency,while multiple cropping index is favorable for promoting agricultural production efficiency. Three-stage DEA model effectively eliminates the influences of environmental and random factors on agricultural production efficiency. After environmental and random factors are eliminated,comprehensive technical efficiency in Taiwan of China declines because of the decline of pure technical efficiency. Each county and city of Taiwan could be divided into different types according to pure technical efficiency and scale efficiency,and it can have some emphasis in improving agricultural production efficiency according to their own efficiency characteristics.

Background:Leishmaniasis is a serious neglected tropical disease that may lead to life-threatening outcome, which species are closely related to clinical diagnosis and patient management. The current Leishmania species determination method is not appropriate for clinical application. New Leishmania species identification tool is needed using clinical samples directly without isolation and cultivation of ***:A probe-based allele-specific real-time PCR assay was established for Leishmania species identification between Leishmania donovani and L. infantum for visceral leishmaniasis (VL) and among L. major, L. tropica and L. donovani/L. infantum for cutaneous leishmaniasis (CL), targeting hypoxanthine-guanine phosphoribosyl transferase (HGPRT) and spermidine synthase (SPDSYN) gene with their species-specific single nucleotide polymorphisms (SNPs). The limit of detection of this assay was evaluated based on 8 repeated tests with intra-assay standard deviation < 0.5 and inter-assay coefficients of variability < 5%. The specificity of this assay was tested with DNA samples obtained from Plasmodium falciparum, Toxoplasma gondii, Brucella melitensis and Orientia tsutsugamushi. Total 42 clinical specimens were used to evaluate the ability of this assay for Leishmania species identification. The phylogenetic tree was constructed using HGPRT and SPDSYN gene fragments to validate the performance of this ***:This new method was able to detect 3 and 12 parasites/reaction for VL and CL respectively, and exhibited no cross-reaction with P. falciparum, T. gondii, B. melitensis, O. tsutsugamushi and non-target species of Leishmania. Twenty-two samples from VL patients were identified as L. donovani (n = 3) and L. infantum (n = 19), and 20 specimens from CL patients were identified as L. major (n = 20), providing an agreement of 100% compared with sequencing results. For further validation, 29 sequences of HGPRT fragment from nine Leishmania species and 22 seque

榜样教育作为高等教育中人才培养的关键手段,对激发学生的积极潜能、塑造积极人格具有不可替代的作用。然而,传统的榜样教育模式往往过于单一和刻板,难以满足当代大学生个性化和多元化的成长需求,面临着榜样形象符号化、教育抽象静态化、学生理解差异化的三重困境。这些困境的根源在于传统教育模式的惯性思维、忽视个体差异的教育实践以及缺乏深度情感共鸣的教育内容。在积极心理学视域下新时期的榜样教育应从三个方面进行改革:榜样塑造的个性化凸显、榜样影响的生活化根基以及榜样教育的体系建构。

全面推进乡村振兴离不开普惠金融的支持,同时也对普惠金融提出了更高的要求。本文基于服务乡村振兴的新视角,从三个维度共13个指标构建西北五省区普惠金融指标体系,采用变异系数法客观赋予指标权重、使用标准欧式距离法测算普惠金融指数。结果显示:西北地区金融服务可得性权重最高但缺乏多元性;存贷款、保险等基础金融服务发展不充分;专项投入比重过低;普惠金融水平整体呈上升趋势,但五省区发展不平衡、差异较大。在此基础上,本文对加速推进普惠金融更好助力乡村振兴提出相关建议。

随着积极心理学、积极组织学术的兴起,积极工作身份概念及相关研究应运而生。本文全面梳理了积极工作身份内涵、研究视角(美德视角、评价视角、发展视角和结构视角)、建构方式及其影响,从社会认同理论、身份工作理论、叙事身份理论和身份理论出发,尝试解决不同内涵间的差异性问题,并分析了积极工作身份形成的机制。研究表明:(1)积极工作身份的个体影响因素包括调节焦点、创伤后成长;情境影响因素包括工作特征、工作同情与亲社会实践;(2)积极工作身份不仅对员工的社会资源、心理功能、工作蓬勃以及身份威胁产生影响,还与组织绩效、高质量关系、凝聚力呈正相关;(3)积极工作身份的建构方式主要有自我叙事、身份工作、工作重塑与关系工作设计。最后,文章还提出了未来研究展望。
