The arrangement of deformation monitoring project and analysis of monitoring data of a hydropower engineering safety monitoring system

The safety monitoring is very important in the operation and management of water resources and hydropower projects. It is the important means to understand the dam running status, to ensure the dam safety, to safeguard people’s life and property security, and to make full use of engineering benefits. This paper introduces the arrangement of engineering safety monitoring system based on the example of a water resource control project. The monitoring results of each monitoring project are analyzed intensively to show the operating status of the monitoring system and to provide useful reference for similar projects.

Mangiferin inhibits cell migration and invasion through Rac1/WAVE2 signalling in breast cancer.

Breast tumour progression results from the advancement of the disease to a metastatic phenotype. Rac1 and Cdc42 belong to the Rho family of genes that, together with their downstream effectors, Wiskott-Aldrich Syndrome protein-family verprolin-homologous protein 2 (WAVE2) and Arp2/3, assume a vital part in cytoskeletal rearrangement and the arrangement of film projections that advance malignant cell relocation and invasion. Mangiferin is a characteristic polyphenolic compound from Mangifera indica L. (Anacardiaceae), ordinarily referred to as mango, that is consumed worldwide as a natural product, including culinary and seasoning applications. Mangiferin delays breast malignancy development and progression by inhibiting different signalling pathways required in mitogenic signalling and metastatic progression. Studies were performed to analyse the impact of mangiferin on Rac1/WAVE2 flagging, relocation and invasion in highly metastatic human MDA-MB-231 mammary cells. Additional studies led to the observation that comparative treatment with mangiferin caused marked reduction in tumour cell movement and invasion. Taken together, these discoveries demonstrate that mangiferin treatment adequately hinders Rac1/WAVE2 flagging and diminishes metastatic phenotypic expression in malignant mammary cells, indicating that mangiferin may provide a benefit as a novel restorative approach in the treatment of metastatic breast cancer.

Identifying Critical Bankability Criteria for PPP Projects: The Case of China

Public‐private partnership (PPP) projects employ a high leverage in terms of debt finance needed by the private consortium. Debt finance providers need to know the bankability‐related issues of PPP projects to make the timely arrangement of debt financing and avoid funding problems. However, there is still a lack of a systematic research on the bankability of PPP projects despite the worsening debt arrangement situation for PPP projects after the credit crisis and economic recession from 2008. To bridge this knowledge gap and enhance the practical debt arrangement of PPP projects, this study aims to identify and prioritize the critical bankability criteria of PPP projects. To achieve the objectives, 41 bankability‐related criteria were first identified from a comprehensive literature. A structured questionnaire survey was then conducted with 31 industry experts in China who worked in financial institutes and had experienced PPP projects to investigate the relative importance of each criterion. To handle the uncertainty and vagueness of the subjective evaluation from surveys, this study analyzed the relative importance weight of each criterion using a proposed fuzzy analytical hierarchy process‐based approach. The results showed that political environment, economic environment, shareholders’ credibility, financial market, legal system, public sector’s reliability, financial structure, and regulatory framework were ranked as the top eight critical bankability criteria. The findings of this study first contributed to the project finance body of knowledge for the bankability of PPP projects. Moreover, the outputs of this study would provide valuable information to the private and public sectors for formulating strategies on improving the bankability of PPP projects.

Mechanisms of Isomorphism in Project-Based Organizations

This article challenges the dominant assumption of goal rationality behind temporary organizations’ design in project-based organizations (PBOs). While extant literature posits that organizations strive to select the most appropriate project arrangements to fit particular task requirements at hand, findings from an in-depth ethnography-inspired case study suggest that projects in PBOs tend to imitate each other's structures, strategies, and practices with little consideration of the potential performance effects. Building upon the new institutionalism, this article conceptualizes the PBO as an organizational field of temporary and permanent organizations embedded in wider organizational and institutional fields and explicates isomorphic processes among temporary organizations in PBOs.

Differentiated Optimization of Sustainable Land Use in Metropolitan Areas: A Demarcation of Functional Units for Land Consolidation

In China, the combination of land supply finitude and land use inefficiency has become a barrier to sustainable development in urban society and the economy. Land consolidation has been widely implemented as a tool to improve the quality and quantity of land use, but is mainly limited to rural areas and focuses on farmland production, while not taking into consideration of aspects such as life, production, and ecology. Furthermore, contemporary research usually focuses on one land consolidation project, ignoring practical project arrangement at a regional macroscopic level and lacking specific differentiation in designing land consolidation projects. This study aims to create a method to determine functional units for land consolidation (FULC) in metropolitan areas to facilitate the sustainable use of land resources and improve the efficiency of land use. Moreover, a framework to assess the overall demarcation of FULC is developed. The proposed model considers the production, life, and ecology functions in the demarcation decisions regarding FULC. A typical metropolitan area, that is, Haidian District, Beijing, is used as a case study to demonstrate this framework. The analysis shows that the model can provide technical support and practical references for planners and executors to arrange different land consolidation projects at the macroscopic level. By taking all production, life, and ecological properties of the land parcels into consideration, the proposed model enables local governments to meet their sustainable development targets by managing specialized projects for FULC as a spatial governance platform.

Cultivated land productivity potential improvement in land consolidation schemes in Shenyang, China: assessment and policy implications

Cultivated land productivity potential improvement (CLPPI) assessment is the fundamental basis to launch land consolidation, which is one of the most important way to increase the grain productive capacity. Previous studies on CLPPI assessment have focused on factors related to natural conditions of cultivated land, but they ignored the impacts of utilization conditions, including plot characteristics and agricultural infrastructure, which account for substantial CLPPI from land consolidation. Based on the crop-growth model and Agro-ecological Zoning (AEZ) methodology, this paper proposed a modified CLPPI assessment model to estimate the improvement of land productivity potential via land consolidation. Meanwhile, the contribute rates of different factors involved in determining the CLPPI were also analysed to reveal the ideal work focus and policy direction for land consolidation. Results showed that the calculated CLPPI values had obvious spatial variety in Shenyang, of which the average was 326.18. For the consolidation case, total crop production in Shenyang could be increased by as much as 149.89×107 kg, 20% of the current yield. CLPPI is the comprehensive outcome of both natural and utilization qualities of land use, and the current productivity potential of cultivated land in Shenyang relied much less on natural conditions such as soil than on utilization conditions such as agricultural infrastructure. In addition, medium-productivity lands were most appropriate target areas for the implication of land consolidation projects. Actually, the arrangement of land consolidation projects should not only consider CLPPI as in the past, but also add the theoretical productivity potential into consideration. Moreover, the realization of estimated CLPPI also calls for active changes of the whole land management system. An integrated institution for the full implementation of land consolidation, proper regulations and laws on the follow-up protection of cultivated land productivity potential, economic policies to stimulate the willingness of farmers, and a transfer mechanism for cultivated land are all needed policy changes.

The encoding of the thermal grill illusion in the human spinal cord

Abstract Aims The spatial alternation of innocuous cold and warm stimuli on the skin can paradoxically provoke a hot, burning sensation, known as the thermal-grill illusion (TGI). Whether the TGI depends on spinal or supraspinal integration mechanisms is still debated. To assess whether the TGI can be accounted by integration of cold and warm afferent signals in the spinal cord, we leveraged anatomical knowledge on the spatial arrangement of dermatomes and spinal segmental projections. Methods We stimulated a series of skin locations on the right arm using one cold (∼20 °C) and one warm thermode (∼40°C). The two stimulus locations had identical physical distance on the skin. However, the distance between the cold and heat projection signals in the spinal cord varied across three conditions. Cold and warm inputs were delivered (1) within the same dermatome (e.g., C5–C5); (2) across the dermatome boundary of two adjacent spinal segments (e.g., C5–C6); (3) across the dermatome boundary of two non-adjacent spinal segments (e.g., C5–T1). In two experiments, we obtained an estimate of the strength of the TGI by asking 32 healthy participants to complete a temperature matching task. Results Participants overestimated the actual average temperature of the two thermodes (Exp. 1) and the cold temperature of one of the two thermodes (Exp. 2). However, this effect was significantly larger when cold and heat stimuli were delivered within the same dermatome (+6.57 ± 3.99°C and +9.88 ± 5.60 °C) or between dermatomes projecting to adjacent spinal segments (+6.26 ±4.44°C and +9.48 ± 5.83 °C), compared to when cold and heat stimuli projected to non-adjacent spinal segments (+3.46 ± 4.46 °C and +4.80 ± 3.21 °C). Conclusions These results demonstrate that the strength of the illusion is modulated by the segmental distance between cold and heat spinal signals, and show that the perceived quality and intensity of thermal stimuli depends upon low-level spatial summation mechanisms in the spinal cord.

PRIORITY BASED AUTOMATIC MULTI SOURCE SWITCHING USING PLC

The main purpose of this project is to provide continuous power supply to the load by switching the supply. In case if anyone of the source is absent from the following four sources namely solar, inverter, mains and generator. Automatically other three provides backup & shares the load .The graph of need of electric supply is growing day by day and the frequent power disconnection of electricity are causing many issues in different areas like banks, colleges schools, hospitals, houses and industries. Thus there is requirement of Energy source for an alternate arrangement of power supply. In this project arrangement has been designed by using Allen Bradely PLC and relays. When a source, say mains fails the power supply to the load then automatically it shifts to next priority source generator and so on. LEDs are used to indication purpose for running source which is used to provide the supply.

Change Management Perspectives in an ERP Module Implementation: A Case Study in a Telecommunication Company

Successful Enterprise Resource Planning (ERP) projects require change management to support the integration of the ERP systems into work environment because ERP imple¬men¬tations involve lots of changes on technical infrastructures, business processes, organization structure, rules and skills of people in the organization. This study was aimed to explain the challenges in implementing an ERP module in a Indonesian telecommunication company, focusing on the change management process involves in the project. A case study at a tele¬com¬munication company was used to collect empirical data and to analyses important aspects of project arrangements that will have an impact on the change management process accompanying the ERP implementation project. The following two aspects of changes were analyzed as the impact of ERP implementation: changes in individual behaviors and changes in the organisational practices. Based on the empirical study, two important aspects of change management effectiveness in the project and post-project stage were highlighted: alignment of the organization structure to support IT-business collaboration and alignment of employee orientation towards effective use of ERP systems. Besides, this study also highlighted that it is important to plan and execute change management process in the post-project stage to obtain benefits from ERP implementation.

THE ROLE OF UMBRELLA AGREEMENTS IN ACHIEVING SUSTAINABILITY GOALS: ENERGY EFFICIENCY AT THE EMPIRE STATE BUILDING

In this paper we investigate whether innovative and flexible contractual arrangements can support the process of achieving ambitious sustainability goals. We explore this question through an analysis of the role of umbrella agreements in driving energy savings in the building sector. Drawing on a case study of the iconic Empire State building, we examine the typical challenges faced by clients and contractors in devising suitable agreements that facilitate managing contractual and performance risks, as well as the sharing of responsibilities and cooperation between multiple project stakeholders. We find that the project arrangements appear to exhibit the adoption of the key characteristics commonly found in umbrella agreements which incorporate sustainability measures that maximize income through efficient delivery of outcomes. Specifically, this means that they need to enable stakeholders to manage repeated review cycles, complex perceptions and expectations, and different tacit assumptions and codes of behaviour, as well as managing and communicating in networks and obtaining agreement also from non-contractual parties. Moreover, we demonstrate that umbrella agreements can facilitate a network perspective of business relationships by emphasizing value co-creation and the embeddedness of firms within a network of interactions.

The study of the investment policy formation of the enterprises as an important factor of their strategic development

Types, peculiarities of investments in the context of transition to an innovative model of economic growth of the country for the short term are specified. The state of the investment climate in Ukraine is studied, the ways of its improvement are defined, the effect of an investment policy on the formation of a corporate development plan is justified. The analysis of an investment activity in Ukraine revealed that macroeconomic indicators are still on the periphery of global investment flows. It was found that the main reasons of decrease in investment activity in Ukraine are: an unfavorable investment climate; inadequate legal framework; poor-quality arrangement of investment projects and programs, as well as their ineffectiveness; imperfection of investment instruments and investment market. Some suggestions concerning the formation of innovative and investment potential using the equity capital of companies are recommended. The principles of the investment policy of enterprises under the conditions of modern management paradigm are stated: the matching principle, the principle of interest and communication skills, the principle of flexibility and alternative, innovative principle, the principle of minimizing of the investment risk. The suggested in the research principles of investment policy make the investment policy of enterprises the tool for enhancement of efficiency of its functioning as a whole for the long term. This study contributes to the definition of the main directions of investment policies of enterprises of Ukraine.

Avoiding Cost Overruns in Construction Projects in India

The main aim of this paper is to identify the major reasons for cost overruns in construction projects in India as well as the critical success factors that are helping to avoid the cost overruns. For this, the existing literature is reviewed and critical success factors are identified. Based on them, survey questions and interview questions are prepared. The findings supported the proposed hypothesis, i.e., lack of certain critical success factors leads to cost overruns in construction projects in India. They also confirmed the proposed proactive and reactive strategies of some researchers. The effective critical success factors include appropriate planning in the initial stages, skills of contractors and architects, good relationship and regular coordination among client and contractor, and early contribution of contractor with the project. The ideal methods that help to reduce cost overruns include efficient planning, proper management of site and supervision of the project, suitable planning and arrangement of project, proper methods for construction, regular meetings on development of the project, and hiring proficient subcontractors and suppliers.

Towards practitioner-initiated interactive knowledge development for sustainable development: A cross-case analysis of three coastal projects

Although the central challenges of sustainable development are well-known, sustainability science has been slow in contributing to effective and feasible solutions for sustainable development. Turning knowledge into action for sustainable development therefore remains a major challenge for sustainability science. Interactive knowledge development is considered a prerequisite for sustainability-oriented action. Most studies approach interactive knowledge development from a researcher's perspective. This paper focuses on practitioners that initiate interactive knowledge development for sustainability-oriented actions. A cross-case analysis is presented for interactive knowledge development in coastal projects. Three cases are analysed through the framework of project arrangements and knowledge arrangements. The projects are located in the Wadden Sea, San Francisco Bay and the Ems estuary and address issues of flood control, nature restoration and liveability. The cross-case analysis revealed 11 causal mechanisms that help explain how project decision-making impacts on interactive knowledge development, how a process of interactive knowledge development functions and what its outcomes are. The mechanisms clarify the key underlying processes of interactive knowledge development in coastal projects. The mechanisms show that interactive knowledge development may result in sustainability-oriented solutions that are feasible for implementation. As such, this paper contributes to a practice-oriented understanding of turning knowledge into action for sustainable coastal development.

Dissecting the Dynamics of Corticothalamic Feedback

The thalamus and neocortex are intimately interconnected via a reciprocal arrangement of feedforward and feedback projections. In this issue of Neuron, Crandall et al. (2015) provide key insight into the functional dynamics of feedback projections and reveal the cellular and circuit mechanisms that underlie a rate-dependent switch in the net influence, suppression versus excitation, that cortex can exert on thalamic relay cells.

Negotiation issues in forming public–private partnerships for brownfield redevelopment: Applying a game theoretical experiment

The redevelopment of a brownfield can provide a range of societal, environmental but also economic benefits for a number of entities. In the Netherlands (and elsewhere), public–private partnerships are common practice for such projects, because of two main reasons. First, limitations to public funding have led governments to invite the private sector into various long-term arrangements for capital-intensive projects. Second, a comprehensive approach for the whole brownfield area may be more efficient and profitable, compared to piecemeal development via interventions by individual owners. This article investigates, with respect to brownfield redevelopment, the interaction behavior of two key parties in forming partnerships: the municipality and a private developer. It is assumed that, apart from their mutual interest to redevelop the brownfield area, they will have different interests as well. In order to indicate their specific interest and the negotiation outcome regarding the forming of a public private partnership, this paper makes use of an experimental game theory approach. Three specific negotiation issues were analyzed in our research: a building claim, future land use and reparcelling of the land. In addition, this paper suggests an eight-step procedure to conduct a game theoretical experiment. A survey was conducted in order to gather the required data for the experiment. The data have been used to estimate the payoffs variations between the two key parties in the mentioned negotiation games. Finally, by comparing sub game perfect Nash equilibrium generated game outcomes and direct expected outcomes of respondents, this paper experimentally proves that the game theoretical analysis provides a valid representation of a real world brownfield redevelopment negotiation within the Dutch institutional-economic context. The outcome of the experiment confirms the Dutch tradition of public private partnerships in urban development practice, with public and private bodies willing to share financial risks and returns in these projects.

Socially robust knowledge in coastal projects

Interactive modes of knowledge production offer a strategy for seeking solutions to complex environmental problems. The outcome of such knowledge production is socially robust knowledge. Social robustness refers to knowledge that is relevant and accepted by actors in the context of its application. This is achieved when knowledge is credible, salient and produced in a legitimate way. To date, only limited research has focused on how social robustness is achieved. As coastal problems are characterised by conflicting interests and major uncertainties, the coastal zone represents a relevant domain for studying socially robust knowledge. This paper analyses and presents three conditions that need to be in place if one is to achieve socially robust knowledge in coastal projects. The conditions are based on theories related to socially robust knowledge, boundary spanning, project arrangements and knowledge arrangements. The conditions specify how social robustness can be achieved through knowledge testing by boundary spanners, the involvement of diverse actors and a close connection between knowledge production and the evolving project. In a case study, these conditions are compared to developments in a Dutch coastal project involving spatial developments near the Ems estuary. The comparison highlights the relevance of the three conditions in achieving socially robust knowledge. In addition, a fourth aspect is empirically uncovered: the role of boundary spanning among project partners prior to producing knowledge. These four conditions clarify how social robustness may be achieved in coastal solutions. As such, this paper contributes to the theoretical and empirical understanding of socially robust knowledge.

Best Practice for Financial Models of PPP Projects

Public-private partnership (PPP) project's arrangement involves many participants with complex transactions and diverse interests at 5 different project stages. Especially in the project financing perspective, this arrangement creates the entire project evaluation process prone to take an extensive period before reaching financial closure. The importance of utilizing financial model as a tool for project evaluation and negotiation is highlighted in this study. 26 input assumptions and 16 output variables have been identified through comparison study of three PPP financial models, and their significances were verified based on pilot studies in India and the UK and expert opinion solicited worldwide through a structured questionnaire survey. SPSS program was used to evaluate the survey responses. The best practice PPP financial model was identified quantitatively by the agreement of four groups of stakeholders (i.e. sponsors, authorities, lenders, and consultants) upon the most preferred financial input and output indicators.
