"后农业税时代"农村公共产品供给问题的研究综述

我国农村已进入“后农业税时代”,在这一背景下农村公共产品供给体制发生了较大变化。我国学者从不同角度对“后农业税时代”农村公共产品供给这一课题给予了多方面的研究。本文主要从农村公共产品的界定与特征;“后农业税时代”农村公共产品供给的现状;“后农业税时代”农村公共产品供给不足的原因分析;“后农业税时代”农村公共产品供给机制的选择等四个方面作了一个文献综述。     

CAREFUL COMMITMENT

New avenues to be explored for Belt and Road cooperation At the beginning of 2021,the situation looks better in China and the rest of the world.China is striving to maintain its success in eliminating COVID-19 cases domestically and fostering immunity for its 1.4-billion population.The more the vaccination process gains ground,the more it is likely that lives will return to normalcy.     

Evaluation and applicability of Alere iCup DX 14 for rapid postmortem urine drug screening at autopsy

Performing point‐of‐care urine drug screen testing at autopsy by a forensic pathologist may provide an early indication of the presence of analytes of interest during autopsy. An evaluation for the screening of 14 classes of common drugs of abuse in postmortem urine by the point‐of‐care screening device, Alere iCup DX 14, is presented. One hundred ninety postmortem urine samples were screened with the iCup occurring at autopsy by the forensic pathologist. Positive and negative results obtained from the screening kit were evaluated against confirmatory test results obtained using routine forensic toxicology analyses that employed LC‐MS/MS and GC‐MS to detect a combination of over 85 common drugs of abuse and medications. Sensitivity for each respective iCup drug class ranged from 66% (buprenorphine) to 100% (methadone, tricyclic antidepressants). Specificity for each respective iCup drug class ranged from 89% (benzodiazepines) to 100% (amphetamines, barbiturates, buprenorphine, 3,4‐methylenedioxymethamphetamine, methadone). Positive predictive values ranged from 44% (benzodiazepines) to 100% (amphetamines, barbiturates, buprenorphine, methylenedioxymethamphetamine, methadone), while negative predictive values ranged from 96% (methamphetamine) to 100% (barbiturates, methadone, tricyclic antidepressants). A high false‐positive rate was yielded by the benzodiazepine class. The lack of fentanyl screening in the point‐of‐care device is a significant limitation considering its prolific prevalence in forensic casework. The results obtained in the study should be acknowledged when considering the use of the Alere iCup DX 14 in the context of postmortem casework to help indicate potential drug use contemporaneously with autopsy and when requiring such preliminary results prior to the release of a final forensic toxicology report.     

At-Large Elections and Minority Representation in Local Government

Despite a long history of legal challenges alleging that elections conducted at-large suppress minority representation, this remains the dominant electoral system in local governments throughout the United States. Moreover, a large empirical literature remains divided over the present-day impact of at-large elections on the political success of underrepresented groups. We reconcile the competing findings in this literature by providing contingent, causal estimates of the effect of conversion from at-large to ward elections on minority officeholding, using a novel identification strategy afforded by the California Voting Rights Act of 2001. We find a dramatic positive effect of conversion in districts where Latinos constitute a sufficiently large share of the voting population, and in large and residentially segregated districts. When these conditions are not satisfied, we consistently see null estimated effects.

金融支持海洋经济发展:粤沪等6省市的主要实践及其对琼启示

党的十九大报告提出“加快建设海洋强国”的战略,《2019年海南省政府工作报告》提出要“做强做优热带特色高效农业和海洋经济”。发展海洋经济,已经成为海南加快建设海洋强省的核心任务。近年来,海南辖区金融机构不断完善金融服务功能,推动海南发展海洋经济建设海洋强省取得积极成效,但工作中仍然存在着政策协同发力不够、金融机构积极性整体偏低等问题;与此同时,粤沪等6省市在发挥金融综合支持效能推动地方建设海洋强省(市)等方面做了很多有益探索。本文旨在通过对粤沪等6省市的主要实践或经验进行总结,并借鉴有益经验,对海南金融支持海洋经济发展存在的问题提出针对性解决方案,为海南金融助力地方培育“蓝色引擎”提供决策参考。
