The role of community in the process of government purchase of social work services - A case study of the purchase of social work services by H District, X City

改革开放以来我国政府逐渐从“大政府，小社会”向“小政府，大社会”的职能转变，政府为民众提供公共服务方式的改变是其中重要的体现。政府购买社会工作服务成为一种新的公共服务的实现方式。在政府具体购买过程中会产生政府、社工机构和服务对象三方，而根据中国国情，服务对象主要是通过社区为主要载体进行服务。 我国政府购买社会工作服务处于初步探索阶段，随着政府购买社工服务的兴起，国内对此方面的研究逐渐增多。目前学者主要集中于对政府购买的理论来源、购买社工服务的必要性、服务的群体、服务机构的专业性及政府角色的转换进行探讨，针对社区在政府购买社工服务过程中的角色缺乏较深的分析。本文旨在通过X市H区参与政府购买社工...Since reform and opening up, the function of Chinese government has gradually transformed from "big government, small society" to “small government, big society”, the change of the government provision of public services for the people is one of the important manifestations. The government purchase of social work services has become a new way to achieve public service. Government, social work agen...学位：法学硕士院系专业：公共事务学院_社会学学号：1402010115053

Hollow Mesoporous Zirconia Nanocapsules for Drug Delivery

While the highly porous feature of the shell allows the drug, doxorubicin(DOX), to easily pass through between the inner void space and surrounding environment of the particles, the void space in the core endows the nanocapsules with high drug loading capacity. The larger the inner hollow diameter, the higher their DOX loading capacity. A loading of 102% related to the weight of hm-ZrO2 is achieved by the nanocapsules with an inner diameter of 385 nm. Due to their pH-dependent charge nature, hm-ZrO2 loaded DOX exhibit pH-dependent drug releasing kinetics. A lower pH offers a faster DOX release rate from hm-ZrO2. Such a property makes the loaded DOX easily release from the nanocapsules when up-taken by living cells. Although the flow cytometry reveals more uptake of hm-ZrO2 particles by normal cells, hm-ZrO2 loaded DOX release more drugs in cancer cells than in normal cells, leading to more cytotoxicity toward tumor cells and less cytotoxicity to healthy cells than free DOX.NSFC 20925103,20871100,20721001 Fok Ying Tung Education Foundation 121011 RFDP 200803841010 NSF of Fujian Province 2009J06005 Key Scientific Project of Fujian Province 2009HZ0002-

The as-prepared Pd@Ag nanoplates are not only uniform in both size and shape, but also display tunable SPR properties and significantly enhanced photothermal stability as compared with 2D pure-Ag nanostructures. They can thus be readily used as stable substrates for MR surface-enhanced Raman scattering and as NIR absorbers for photothermal cancer therapy.NSFC 21021061,20925103,20923004,20871100 Fok Ying Tung Education Foundation 121011 MOST of China 2011CB932403,2009CB930703 NSF of Fujian Province 2009J06005 Key Scientific Project of Fujian Province 2009HZ0002-

Etching Growth under Surface Confinement: An Effective Strategy To Prepare Mesocrystalline Pd Nanocorolla

通讯作者地址: Zheng, NF (通讯作者),Xiamen Univ, Coll Chem & Chem Engn, State Key Lab Phys Chem Solid Surfaces, Xiamen 361005, Peoples R China 地址: 1. Xiamen Univ, Coll Chem & Chem Engn, State Key Lab Phys Chem Solid Surfaces, Xiamen 361005, Peoples R China 2. Xiamen Univ, Coll Chem & Chem Engn, Dept Chem, Xiamen 361005, Peoples R China 电子邮件地址: [email protected] etching growth strategy was developed to prepare corolla-like Pd mesocrystals consisting of unidirectionally aligned, well-spaced, and connected ultrathin (1.8-nm-thick) Pd nanosheets. The combined use of CO and Fe(3+) is critical to the successful synthesis of the branched corolla-like Pd mesocrystals. While CO functions as the surface-confining agent to allow anisotropic growth of the 1.8-nm-thick Pd nanosheets as branches, Fe(3+) etches the Pd seeds at the early stage of the reaction to induce formation of the branched structure. Inheriting the unique properties of 1.8-nm-thick Pd nanosheets, the as-prepared Pd mesocrystals display well-defined surface plasmon resonance absorption in the near-infrared region, a high electrochemically active surface area, and a significant photothermal effect when irradiated with a near-infrared laser. Owing to the presence of internal voids and increased apparent thickness, the Pd mesocrystals also exhibit several features superior to those of single-domain Pd nanosheets, making them promising for electrocatalysis and cancer photothermal therapy applications.NSFC 21131005 21021061 20925103 20871100 Fok Ying Tung Education Foundation 121011 MOST of China 2011CB932403 2009CB930703 NSF of Fujian Province 2009J06005 Key Scientific Project of Fujian Province 2009HZ0002-
