abstract = {A problem of visiting megalopolises with a fixed number of "entrances" and precedence relations defined in a special way is studied. The problem is a natural generalization of the classical traveling salesman problem. For finding an optimal solution, we give a dynamic programming scheme, which is equivalent to a method of finding a shortest path in an appropriate acyclic oriented weighted graph. We justify conditions under which the complexity of the algorithm depends on the number of megalopolises polynomially, in particular, linearly.},

We also suggest a new way of measuring corporate e-reputation and its determinants. We quantitatively analyze the effect of Wikipedia and its key features on the corporate e-reputation of companies that are listed on the French stock market SBF 120®. Our results show that Wikipedia has an impact on corporate e-reputation across several dimensions, including the articles' quality and reputation, the latter resulting from a combination of the authors' rigor and diversity, and the immediacy of information provision.},

Furthermore, the tool that defines which project is eligible to the French research tax credit came as a solution to homogenise the different interpretations of multiple consultants working for the same client.},

abstract = {For the last two decades, most financial markets have undergone an evolution toward electronification. The market for corporate bonds is one of the last major financial markets to follow this unavoidable path. Traditionally quote-driven (i.e., dealer-driven) rather than order-driven, the market for corporate bonds is still mainly dominated by voice trading, but a lot of electronic platforms have emerged. These electronic platforms make it possible for buy-side agents to simultaneously request several dealers for quotes, or even directly trade with other buy-siders. The research presented in this paper is based on a large proprietary database of requests for quotes (RFQ) sent, through the multi-dealer-to-client (MD2C) platform operated by Bloomberg Fixed Income Trading, to one of the major liquidity providers in European corporate bonds. Our goal is (i) to model the RFQ process on these platforms and the resulting ...},

The second one, called Shliomis model, is obtained by assuming that the angular momentum is given in terms of the magnetic field, the magnetization field and the vorticity. It consists of the incompressible Navier-Stokes equation, the magnetization equation and the magnetostatic equations. We prove, for each of the differential systems posed in a bounded domain of R3 and equipped with boundary conditions, existence of weak solutions by using regularization techniques, linearization and the Schauder fixed point theorem.},

Starting from the Gaussian approach of Liu et al.

In a Wishart affine model, which allows for a non-trivial dependence between the mortality and the interest rates, we go far beyond the results found in the Gaussian case by Liu et al. (2014), where the value of these insurance contracts can be explained only in terms of the initial pairwise linear correlation.},

abstract = {Pipelines are the very important energy transmission systems. Over time, pipelines can corrode. While corrosion could be detected by in-line inspection (ILI) tools, corrosion growth rate prediction in pipelines is usually done through corrosion rate models. For pipeline integrity management and planning selecting the proper corrosion ILI tool and also corrosion growth rate model is important and can lead to significant savings and safer pipe operation. In this paper common forms of pipeline corrosion, state of the art ILI tools, and also corrosion growth rate models are reviewed. The common forms of pipeline corrosion introduced in this paper are Uniform/General Corrosion, Pitting Corrosion, Cavitation and Erosion Corrosion, Stray Current Corrosion, Micro-Bacterial Influenced Corrosion (MIC). The ILI corrosion detection tools assessed in this study are Magnetic Flux Leakage (MFL), Circumferential MFL, Tri-axial MFL, and Ultrasonic Wall Measurement (UT). The corrosion growth rate models considered in this study are single-value corrosion rate model, linear corrosion growth rate model, non-linear corrosion growth rate model, Monte-Carlo method, Markov model, TD-GEVD, TI-GEVD model, Gamma Process, and BMWD model. Strengths and limitations of ILI detection tools, and also corrosion predictive models with some practical examples are discussed. This paper could be useful for those whom are supporting pipeline integrity management and planning.},

The technique is based on an extended homogenization scheme where the averaging operators are replaced by linear filters to cut off fine scale fluctuations, while maintaining locally varying mechanical fields with larger wavelength. As a result, the constitutive law at an intermediate scale, called mesoscale, arises to be naturally nonlocal by construction, where the kernel operator is fully constructed by computations on the unit cell associated with the microstructure.},

processes in play as workers' voice, vicarious voice, international campaigning,

and multi-scalar industrial action and shows how such processes lead to

particular forms of labour regulation in GVCs. Two pathways are identified

that include context variables and processes and lead to the implementation

of regulatory mechanisms: the consumer power pathway and the labour

power pathway. We then describe and analyze the factors that determine

the shift from implementation to actual outcomes thereby contributing to a

better understanding of the issue in theory and practice.},

Based on a survey about external knowledge sourcing activities of Chinese innovative firms, we categorize external knowledge sources into four groups: science-based partners; horizontal connections; value chain partners, and technology service providers. We find that both internal R&D activities and external knowledge sourcing have a positive effect on firms' innovation performance. Strong internal R&D capabilities also increase the effect of sourcing from value chain partners and horizontal connections, but we do not find support for complementarity between internal R&D and collaborations with universities and research labs. These findings jointly suggest that the mixture of different types of external knowledge partners in combination with internal R&D capabilities is crucial in understanding the role of open innovation in emerging economies.},

abstract = {The concept of open innovation encompasses a wide range of external actors that an organisation might need to share and acquire knowledge with. While there is much hype about open innovation, as of yet there is no framework to decide how open innovation might be useful. In our research we cite four theories linked with open innovation. Through the literature analysis, we develop a framework called 'competitive innovation matrix' for using open innovation within project development, at the very start of the process. The framework is to be tested in future empirical research work. We aim to highlight that open innovation, when applied prior to close innovation, would rather shift from being a risk to being an opportunity. In any case, when a firm share its ideas open, it would expect to receive others' ideas as well. Accordingly, we provide an overall framework for employing both open and closed innovation, one that shows how open innovation has clear benefits for sharing problem solving at the initial research phase of the project.},

The results show that employees in Russian MNCs with a lower level of corporate language skills will be less likely to consider vertical and horizontal career mobility than employees with a higher level of these language skills. Equally, employees in Russian MNCs with a lower level of corporate language skills will be less likely to consider internal and external career mobility than those employees with a higher level of these language skills. We prove that corporate language may act both as a barrier and as a facilitator for the career mobility of employees in Russian MNCs who have different levels of corporate language skills.},
