1 Financial market frictions and diversification
اصطکاک ها و گوناگونی بازار مالی-2018
We find new facts that relate the evolution of firm scope to the changing frictions in external capital markets over the last three decades. We find that large, diversified publicly traded firms increase their scope during times of high external capital market frictions, such as in the recent Great Recession. Moreover, during these times firms diversify their investment needs and cash flow across industries. We also find similar phenomena outside diversified public firms. Examining the mergers and acquisitions activity of stand-alone and diversified private firms, we uncover similar patterns. In aggregate data, we find that the composition of mergers shifts from focused to diversifying and back with changes in external market conditions. Our evidence is broadly consistent with the notion that firms diversify their scope in response to tightening in external capital markets.

2 Investigating the feasibility of a reuse scenario for textile fibres recovered from end-of-life tyres
بررسی امکان سنجی یک طرح استفاده مجدد برای فایبرهای بافتی بازیابی شده از لاستیک های به پایان راه رسیده-2018
The management of end-of-life tyres (ELTs) is regulated by several national and international legislations aiming to promote the recovery of materials and energy from this waste. The three main materials used in tyres are considered: rubber (main product), which is currently reused in other closed-loop applications; steel, which is used for the production of virgin materials; and textile fibres (approximately 10% by weight of ELTs), which are mainly incinerated for energy recovery (open-loop scenario).
This study aims to propose and validate a new closed-loop scenario for textile fibres based on material reuse for bituminous conglomerates. The final objective is to verify the technical, environmental, financial, and economic feasibility of the proposed treatment process and reuse scenario. After characterization of the textile material, which is required to determine the technological feasibility, a specific process has been developed to clean, compact, and prepare the fibres for subsequent reuse. A life cycle assessment (LCA) has been carried out to quantify the environmental benefits of reusing the fibres. Finally, a cost benefit analysis based on the LCA results was conducted to establish the long-term financial and economic sustainability.
From a technological point of view, the tyre textile fibres could be a promising substitute to the reinforcement cellulose commonly used in asphalts as long as the fibres are properly prepared (compaction and pellet production) for application in the standard bituminous conglomerate production process. From an environmental point of view, relevant benefits in terms of global warming potential and acidification potential reduction were observed in comparison with the standard incineration for energy recovery (respectively −86% and −45%). Moreover, the proposed scenario can be considered as financially viable in the medium to long term (cumulative generated cash flow is positive after the 5th year) and economically sustainable (expected net present value of more than €3,000,000 and economic rate of return of approximately 30%). Finally, the sensitivity and risk analyses show that no specific issues are foreseen for the future implementation in real industrial applications.
