Research on practice of government's purchasing social work services from Public Administration Perspective —— with XM city as an example

2006年，我国真正开启了社会工作职业化进程。经过近十年的努力，社会工作发展的体制机制更加健全、人才队伍越来越壮大。在这个过程中，全国各地积极推进政府购买社会工作服务，实践经验逐步丰富，政策制度不断完善，购买资金量不断上升。XM市自2007年以来，也不断加大力度推进社会工作专业人才队伍建设，并于2010年开始了政府购买社会工作服务的探索，至今取得不少成就。近两三年，国内学者对政府购买社会工作服务进行了许多研究，但对XM市这方面工作的研究较少，而XM市的政府购买社会工作服务实践在国内二三线城市是有一定代表性的。鉴于此，笔者期望，以公共管理为视角，以新公共管理理论的企业家政府模式为指导，立足XM市...In 2006, the process of China’s social work’s professionalism has been truly launched. After nearly 10 years of efforts, with the development of the social work system and mechanism, the growth of professional procession, the whole country actively promote the government’s purchasing social work services, which leads to the increasing of practice experience, the perfection of the policy system and...学位：社会工作硕士院系专业：公共事务学院_社会工作硕士学号：1402014115052

JUNO Sensitivity on Proton Decay p→νˉK+p\to \bar\nu K^+ Searches

The Jiangmen Underground Neutrino Observatory (JUNO) is a large liquid scintillator detector designed to explore many topics in fundamental physics. In this paper, the potential on searching for proton decay in $p\to \bar\nu K^+$ mode with JUNO is investigated.The kaon and its decay particles feature a clear three-fold coincidence signature that results in a high efficiency for identification. Moreover, the excellent energy resolution of JUNO permits to suppress the sizable background caused by other delayed signals. Based on these advantages, the detection efficiency for the proton decay via $p\to \bar\nu K^+$ is 36.9% with a background level of 0.2 events after 10 years of data taking. The estimated sensitivity based on 200 kton-years exposure is $9.6 \times 10^{33}$ years, competitive with the current best limits on the proton lifetime in this channel

JUNO sensitivity on proton decay p → ν K + searches*

The Jiangmen Underground Neutrino Observatory (JUNO) is a large liquid scintillator detector designed to explore many topics in fundamental physics. In this study, the potential of searching for proton decay in the $p\to \bar{\nu} K^+$ mode with JUNO is investigated. The kaon and its decay particles feature a clear three-fold coincidence signature that results in a high efficiency for identification. Moreover, the excellent energy resolution of JUNO permits suppression of the sizable background caused by other delayed signals. Based on these advantages, the detection efficiency for the proton decay via $p\to \bar{\nu} K^+$ is 36.9% ± 4.9% with a background level of $0.2\pm 0.05({\rm syst})\pm$$0.2({\rm stat})$ events after 10 years of data collection. The estimated sensitivity based on 200 kton-years of exposure is $9.6 \times 10^{33}$ years, which is competitive with the current best limits on the proton lifetime in this channel and complements the use of different detection technologies
