Authors: Xu Shunqing , Liu Shuangliu , Cheng Liang , Gao Jun , Chen Peng
Published: December 2019

Financial calculation is an important part in the PPP project investment decision. In PPP practice, the selection of financial calculation indicators is quite arbitrary, which is prone to fairness imbalance between PPP projects to a certain extent and even affects project decision-making. Financial calculation indicators usually used in the PPP scheme design include financial internal rate of return, return on investment, reasonable profit rate, annual interest rate, etc. Based on the economic meanings of the four types of indicators and combined with specific cases, the study analyzes the quantitative relation and applicability between different indicators. When the PPP project involves as long a period as 20 to 30 years, it is recommended to use dynamic indicators (financial internal rate of return) rather than static indicators (return on investment, reasonable profit rate, annual interest rate) in the project investment decision. When dynamic indicators are selected, it is more suitable for the public sector to adopt the internal rate of return on investment without considering the financing cost and debt repayment. For private sector, the internal rate of return of the project capital reflects the profit after the financial leverage using equity fund, with more realistic reference significance.

The final choice is often not to participate in the knowledge contribution, and this will damage its actual interests; (2) under the principal-agent game model of the contractor and the engineering project team, the engineering project team needs to continuously increase knowledge and improve technology to achieve the increase of marginal revenue; (3) in the three-party principal-agent game model of the owner, contractor and supervisor, the rent-seeking relationship between the supervisor and the contractor will affect the overall project efficiency, so it should be particularly vigilant. Finally, based on the above results, the countermeasures and suggestions for the collaborative construction management of multi-agents inside and outside the engineering project team are proposed.
The determinants of reward-based crowdfunding project delivery performance: A configurational model based on Latent Dirichlet Allocation
Authors: Wang Yijing , Yi Feng , Hu Junhao
Published: December 2019

Reward-based crowdfunding (BRCF) projects as the most popular crowdfunding model, the funders expect the project owners to deliver the promised rewards within the specified delivery time. Previous studies examined various factors such as level and amount of funding received, project category and size that might influence the reward delivery performance. However, textual information of projects has rarely been studied for analyzing on time or late delivery. The main contribution of our research is applying text analytical framework that can extract latent semantics from the textual descriptions of projects to predict the reward delivery performance. More specifically, we use the Latent Dirichlet Allocation (LDA) topic model for effective extraction of topical features to form a configuration model, and Qualitative Comparative Analysis (QCA) was conducted for the antecedent factors. The findings indicate that the configurational model has high consistency and coverage, which indicate sufficient antecedent conditions for on-time and late delivery. The asymmetric analysis of this study also supports the application of complexity theory in the field of crowdfunding, which offers insights into the setting of appropriate antecedent conditions to achieve on-time delivery. The managerial insights are also discussed in the paper.

There are many classification methods for temporary plugging volume fracturing. According to different temporary plugging positions and temporary plugging targets, temporary plugging volume fracturing technology can be divided into temporary plugging in fractures and temporary plugging between fractures. According to the number of temporary plugging, it can be divided into one temporary plugging and multi-level temporary plugging. According to the action mode of temporary plugging, it can be divided into physical temporary plugging and chemical temporary plugging. According to the type of temporary plugging agent, it can be divided into plugging balls (plastic balls, rubber balls, nylon balls, wax balls) temporary plugging, fiber temporary plugging, large particle size proppant temporary plugging, etc. In Changqing, Daqing and Xinjiang oilfields in China, temporary plugging agents have been reported to be used for in-fracture diversion fracturing to improve reservoir productivity, and certain effects have been achieved. Compared with conventional staged fracturing, the temporary plugging of the seam to fracturing technology has the following advantages: conventional staged fracturing is difficult to implement, the temporary plugging of the seam to fracturing technology can be used to realize effective layering (segment) reconstruction, general fracturing reconstruction is insufficient, and temporary plugging of the seam to fracturing can be used to improve thereconstruction effect.

Project portfolio includes numerous projects and there are interactions and dependencies between projects. To overcome the shortcomings of traditional project portfolio evaluation methods, this paper proposes a project priority ranking method based on complex network theory and PageRank algorithm. This paper firstly analyses the dominance relationships among projects based on the establishment of evaluation criteria for projects; furthermore, deliverable-to-project multi-domain matrix (MDM) is established to measure the dependency relationship between projects based on design structure matrix (DSM). Considering the dominance and dependency of projects, this paper constructs a priority ranking model for projects based on the PageRank algorithm. Finally, taking the project portfolio selection for the construction of maritime search and rescue (SAR) system-of-systems (SoS) as an example, the ranking problem is discussed.

Assembled steel structure housing has the advantages of low cost, light weight and flexible space arrangement, which has been largely used in government-subsidized housing in China. Meanwhile with the rising of assembled steel structure housing, precast concrete facade panels have been widely used. In this paper, the research on the seismic performance of assembled steel frame with precast concrete facade panels in China is summarized and discussed, including the influence of precast concrete facade panels, flexible connections and the seismic performance of steel frame influenced by precast concrete facade panels. According to the research status, the mechanical characteristic of the precast concrete facade panels following the deformation of steel frames; the seismic performance influence of the main structure in rare earthquakes because of the flexible connections are analysed. This paper provides a reference for seismic theory establishment of assembled steel structure housing envelope system.

The identification of garbage at several points along the Badung river shows a low level of public awareness of the environment. The origin of the contents of the garbage in the Badung river comes from various human activities such as industry, household and nature. Although there is a trash rack, but it is not optimal in reducing plastic waste carried on the river. There are several reasons that cause people to throw garbage into the river. Among other things, disposing of garbage into the river is considered more practical and freer, the lack of garbage disposal facilities around the river and has become a culture. Therefore, research was conducted on community behaviour in disposing of garbage along the Badung river. The results showed trigger factors variable with a very influential factor, namely the existence of a disease of 79%. And as many as 5% of the people feel that the availability of Temporary Disposal Site facilities has no effect. The waste management system will be managed directly by the Waste Self-Management Group in each village, as an effort to build an integrated system. It also educates the public how to sort, manage and utilize waste. With the proper governance, of course, it can reduce the volume of waste to landfill.
