索道管的安装定位一直是斜拉桥主塔和主梁施工的难点,其安装精度直接影响到拉索的受力状况,从而影响工程质量和斜拉索的使用年限。本文根据梅州城区广州大桥的施工实践,通过改进传统的索道管定位方法,扼要叙述了斜拉桥索道管安装定位技术。     

Guarded dual authentication based DRM with resurgence dynamic encryption techniques

Cloud computing is the emergent technology that face one of the significant issues time with data security while outsourcing the data onto the cloud in recent. Some cryptographic techniques have been used for protection in form of identity, attributes and prediction algorithms nonetheless these algorithms lack their performance and becomes are very prone to attackers when an unauthorized user reunited the system with dissimilar way for privileges to the similar data files. The essential need of this data security solved by some enhanced cryptographic techniques in DRM utilizing a secure privacy preserving data sharing with encryption techniques of Dynamic Unidirectional Proxy Re-Encryption. This technique is based on Cipher text Policy Attribute by providing the privacy, integrity and security of the data while retrieving.

“双碳”目标下我国森林保险创新发展研究

摘 要：党中央高度重视生态文明建设,“双碳”目标建设作为生态文明建设的核心,对生态碳抵消提出了极高要求。在“双碳”目标建设中,森林资源保护与发展贡献了巨额生态碳汇,而森林保险能有效分散森林经营风险,扩大森林固碳规模,对实现“双碳”目标意义重大。本文分析了森林保险赋能“双碳”目标的作用机制,总结了组织制度不完善、法律法规缺位、保费补贴不均衡、产品体系存在缺陷、经营能力差和保险费率固定等问题。本文借鉴国外森林保险赋能“双碳”目标的经验,从政府层面提出优化多方合作机制、加快森林保险立法、完善差异化补贴制度等政策建议;从保险企业层面提出构建科学产品体系、利用保险科技打通业务流程、强化费率差异化水平等措施建议,以期推动我国森林保险创新发展,助力“双碳”目标稳定实现。     

市场约束、显性存款保险制度与银行风险承担——基于回归控制法的研究

基于我国利率市场化进程日趋完善和新推出显性存款保险制度的金融大背景,本文从市场约束与显性存款保险制度的视角,将显性存款保险制度政策视为一个“准自然实验”,采用2010~2016年的面板数据,研究了存款保险制度及其与市场约束的相互作用对银行风险承担的影响,并藉此评价了其政策效应。研究结果表明:(1)我国不同类别商业银行的两类市场约束效应存在较大差别。就价格约束效应而言,对地方银行显著有效,而对全国性银行和外资银行则不显著;就数量约束效应而言,三类银行均不显著。(2)基于回归控制法的估计结果表明,存款保险制度的实施对银行风险承担有显著的正向影响,且其对地方银行的冲击强于全国性银行。(3)进一步基于非线性双重差分的估计结果显示,存款保险制度显著弱化了市场约束对银行风险承担的负向影响,表明我国存款保险制度的政策影响逐渐开始发挥出来。     

农村可再生能源联合发电系统及关键技术与标准化

单一可再生能源,都有各自的优势和弱点。农村地区应根据当地现有可再生能源资源,采用因地制宜、有机联合的发电方式,可达到扬长避短、降低成本的效果,使农村这一广阔的市场成为我国可再生能源战略的主战场,对实现低碳经济、孕育农村新能源产业意义重大。     

钢筋砼人工湖(池)施工的质量控制

针对以往钢筋混凝土水池施工所暴露的问题,福建林业职业技术学院江南新校区人工湖在夏季温度较高的施工条件下,通过采取一系列施工技术措施——处理好水池基底、严格控制混凝土温度、降低内外温差、处理好池体变形缝、施工缝等保证了工程的质量,抗渗试验效果良好。     

资金供给、技术能力与技术转移绩效——国家重点研发计划多群组结构方程模型分析

国家重点研发计划对全产业链的强调使得研究其技术转移尤为必要。参考资源基础理论和动态能力理论,构建“资金供给—技术积累规模—技术转移能力—技术转移绩效”国家重点研发计划技术转移模型。应用结构方程模型进行检验,使用多群组结构方程模型探讨不同研究项目各因素对技术转移绩效的不同影响。结果发现：(1)国家重点研发计划技术转移绩效总体处于较高水平;(2)技术转移能力是国家重点研发计划技术转移绩效最直接、最有力的影响因素,资金供给是技术转移绩效的重要支撑;(3)技术积累规模难以直接影响技术转移绩效,但在技术转移绩效影响机理中发挥重要传导作用,是技术转移的基础性技术资源;(4)不同项目类型影响效应存在显著差异。研究结论可为政府、项目参与单位、首席科学家和普通参与者有效促进科技项目技术转移提供参考依据。     

Research productivity of Australian accounting academics

In recent decades, substantial changes have impacted the global academy, such as the increasing use of key performance metrics for academics. This study provides recent evidence of Australian accounting academics’ performance in publishing in A/A* journals during the period 2010–2018. We find that the top 25 percent of Australian academics produce approximately 60 percent of published journal articles through an analysis of the A/A* Australian Business Deans′ Council (ABDC) accounting journal listing. The majority of published Australian co‐authored research output in the sample is in A ranked journals (80 percent), with only 20 percent observed in A* ranked journals.     

Social media resources and capabilities as strategic determinants of social media performance

Recent research reveals meaningful uses of digital marketing instruments, though without addressing internal, organizational antecedents of a firm’s social media performance. Drawing on resource-based theory and the concept of dynamic capabilities, this article identifies social media–specific resources and dynamic capabilities that can enhance social media performance. It also offers theoretically supported and validated scales to measure them. The authors empirically investigate their performance effects using different kinds of data pertaining to consumer brands, gathered from manager surveys, brands’ financial statements, Facebook fans, Instagram followers, YouTube subscribers, and brand image measures. The proposed social media resources and capabilities improve social media performance directly and brand perception indirectly. In particular, the impact of the social media strategy and measurement is moderated by firm size. A profile deviation analysis further reveals that the social media capabilities gap between top-performing versus other brands explains significant variance in social media performance. The advantages of developing social media capabilities early on also persist in the long-term, with substantial relevance for managers.
