However, few frameworks exist that allow for a comparative examination of existing policy instruments, as opposed to specific initiatives, which assess governance performance aimed at addressing issues arising in the coastal zone. This paper describes the process and findings for evaluating the feasibility of a modified Coastal Sustainability Standard (CoSS) framework that seeks to measure the effectiveness of individual planning instruments within overlapping spatial boundaries in the landward and marine areas in the southeast region of Cuba. Through workshops conducted in Santiago de Cuba and Guamá municipalities with key representatives involved in coastal management and planning, the utility of the framework was assessed using the main instruments of territorial planning in Cuba, namely integrated river basin management, territorial planning in coastal municipalities and marine and coastal management. While, the findings suggest that the modified CoSS framework can be used to assess the effectiveness of these planning instruments in the region, and workshop participants also suggested improvements to better match its use to the characteristics of the study region.展开更多

Water constitutes a principal stake of these environmental policies in the majority of the countries and especially in the countries of North Africa as Algeria, where this resource is threatened by repeated dryness and by the impact of the climate change. The integrated water resource management reflects today the world tendency of the governments to exploit and preserve this resource by a way based on a process of governance, which passes by the dialog of diversified actors (various sectors). According to this policy and to the promulgation of the Algerian National Report on State effective implementation and coordination mechanisms are required. How this principle of integrated water management will be executed with various scenarios in Algeria and what are the main difficulties that can be met? Or, more exactly, what are the variables that can influence the operation of the local water process governorship? This analysis will be carried out through the example of the Wadi El K6bir watershed located in the northeast of Algeria, which is real natural area of water supply that feeds the communities, the natural and artificial basins, and preserves the perenniality of the existing natural ecosystems especially the one of the natural park classified by the United Nations Educational Scientific and Cultural Organization (U.N.E.S.C.O) in 1989 as the inheritance of humanity and six other sites classified according to the Ramsar convention as wetlands of international importance to be preserved.展开更多

Germany announced the Industry 4.0 strategy in 2013. The US government launched the Advanced Manufacturing Partnership (AMP) in 2011 and the National Network for Manufacturing Innovation (NNMI) in 2014. Most recently, the Manufacturing USA initiative was officially rolled out to further "leverage existing resources... to nurture manufacturing innovation and accelerate commercialization" by fostering close collaboration between industry, academia, and government partners. In 2015, the Chinese government officially published a 10- year plan and roadmap toward manufacturing: Made in China 2025. In all these national initiatives, the core technology development and implementation is in the area of advanced manufacturing systems. A new manufacturing paradigm is emerging, which can be characterized by two unique features: integrated manufacturing and intelligent manufacturing. This trend is in line with the progress of industrial revolutions, in which higher efficiency in production systems is being continuously pursued. To this end, 10 major technologies can be identified for the new manufacturing paradigm. This paper describes the rationales and needs for integrated and intelligent manufacturing (i2M) systems. Related technologies from different fields are also described. In particular, key technological enablers, such as the Intemet of Things and Services (IoTS), cyber-physical systems (CPSs), and cloud computing are discussed. Challenges are addressed with applica- tions that are based on commercially available platforms such as General Electric (GE)'s Predix and PTC's ThingWorx.展开更多

Rural energy systems, as one of the important links of the energy network in China, suffer from low energy efficiency and weak infrastructure. Therefore, it is particularly important to increase the proportion of electricity consumption and build an integrated energy system for rural electrification in China(IESREIC) with a rural distribution network as the core, in line with national conditions. In this study, by analyzing the Chinese regional differences and natural resource endowments, the development characteristics of the IESREIC are summarized. Then, according to the existing rural energy problems, key technologies are proposed for the IESREIC, such as those for planning and operation, value sharing, infrastructure, and a management and control platform. Finally, IESREIC demonstration projects and business models are introduced for agricultural production, rural industrial systems, and rural life. The purpose is to propose research concepts for the IESREIC, provide suggestions for the development of rural energy, and provide a reference for the construction of rural energy systems in countries with characteristics similar to those of China.展开更多

The usage of proprietary integration products results in the increased cost of enterprises. During the integration, the focus area has been found to often address only the functional requirements, while the non-functional requirements are side-stepped during the initial stages of a project. Moreover, the use of proprietary integration products and non-standards-based integration platform has given rise to an inflexible integration infrastructure resulting in adaptability concerns. Web services-based integration, based on open standards, is deemed to be the only feasible solution in such cases. This paper explains the performance analysis of enterprise integration in heterogeneous environments for the distributed and the transactional applications. The analysis presented in this paper is seen as a step towards making intelligent decisions well in advance when choosing the integration mechanism/products to address the functional as well as the non-functional requirements considering the future integration needs.展开更多

Afterseveral steps of subcloning donor DNA into the isiAB fragment, a donor plasmid pZL which could be inte-grated into the chromosomal DNA of Synechococcus sp. PCC7942 was constructed. In order to express theheterologous gene at a high level through the integration platform system, we constructed the donor DNAby the following steps. We cloned the strong promoter (240 bp) of heat shock gene groESL operon fromSynechococcus sp. PCC7942 by PCR. Then subcloned the multiple cloning sites (MCS), rbcS polyA intothe downstream of the groESL promoter. The kanamycin resistance gene, as the marker gene, was alsosubcloned into the donor DNA. Thus, in the donor plasmid pZL, the integration homologous fragment andseveral expression elements, such as groESL promoter, MCS, rbcS polyA teminator and kanamycin re-sistance gene, were all included.After naturally transformed and introduced the donor plasmid pZL into Synechococcus sp. PCC7942,as in the pZL, the donor DNA sequence is flanked by two DNA fragments (0.4 kb and 0.7 kb) homolo-gous to the isiAB fragment of Synechococcus sp. PCC7942, the homologous DNA can recombine with thechromosomal DNA. After screening by kanamycin, the transformants which integrated the heterologousDNA were selected. The efficiency of transformation is about 1×10-6. By southem blot analysis, it wasconfirmed that the donor DNA had been integrated into the chromosomal DNA of Synechococcus sp.PCC7942, located on the site of the isiAB gene, and can be replicated with the chromosomal DNA.展开更多

文摘The platform economy has become a new engine and leading force for China's economic development.With the rapid development of super internet platforms, this field has drawn growing attention from attention of anti-monopoly authorities.The technical attributes and business characteristics of the platform economy endow those platforms with a "natural" monopoly advantage, and the quasi-public attributes of the internet platforms require anti-monopoly authorities to bear more monopoly governance responsibilities.This paper analyzes the difficulties in monopoly governance of the platform economy from the perspectives of anti-monopoly legislation, government regulation and global monopoly governance, and proposes several solutions and suggestions to improve the effectiveness of anti-monopoly governance and promote healthy development of the digital economic ecology.The solutions and suggestions include: focusing on building up technology-based regulatory capabilities, accelerating the legislation on data protection of data, and developing an anti-monopoly system based on the principle of giving priority to innovation.
文摘According to the known sequence of iron stress-induced gene (isiAB operon), wecloned its 1. 5 kb fragment by PCR, and used this Fragment as integration homologous fragment. Afterseveral steps of subcloning donor DNA into the isiAB fragment, a donor plasmid pZL which could be inte-grated into the chromosomal DNA of Synechococcus sp. PCC7942 was constructed. In order to express theheterologous gene at a high level through the integration platform system, we constructed the donor DNAby the following steps. We cloned the strong promoter (240 bp) of heat shock gene groESL operon fromSynechococcus sp. PCC7942 by PCR. Then subcloned the multiple cloning sites (MCS), rbcS polyA intothe downstream of the groESL promoter. The kanamycin resistance gene, as the marker gene, was alsosubcloned into the donor DNA. Thus, in the donor plasmid pZL, the integration homologous fragment andseveral expression elements, such as groESL promoter, MCS, rbcS polyA teminator and kanamycin re-sistance gene, were all included.After naturally transformed and introduced the donor plasmid pZL into Synechococcus sp. PCC7942,as in the pZL, the donor DNA sequence is flanked by two DNA fragments (0.4 kb and 0.7 kb) homolo-gous to the isiAB fragment of Synechococcus sp. PCC7942, the homologous DNA can recombine with thechromosomal DNA. After screening by kanamycin, the transformants which integrated the heterologousDNA were selected. The efficiency of transformation is about 1×10-6. By southem blot analysis, it wasconfirmed that the donor DNA had been integrated into the chromosomal DNA of Synechococcus sp.PCC7942, located on the site of the isiAB gene, and can be replicated with the chromosomal DNA.
