“…Nevertheless, the contribution percentages of these top eight countries amounted to 78%. These data confirmed the existence of a reduced number of countries that dominate the publication of documents in this research field, in a similar way to other topics, including the full list of engineering branches [45,78,79]. However, a more in-depth look at the countries in Table 3 concluded that the research in this topic was clearly led by European countries, since USA was the unique top country that did not belong to the European Union.…”

A bibliometric analysis of the Scopus database was carried out to identify the research trends related to hemicellulose valorization from 2000 to 2016. The results from the analysis revealed an increasing number of annual publications, a high degree of transdisciplinary collaboration and prolific contributions by European researchers on this topic. The importance of a holistic approach to consider the simultaneous valorization of the three main components of lignocellulosic biomass (cellulose, hemicellulose and lignin) must be highlighted. Optimal pretreatment processes are critical for the correct fractionation of the biomass and the subsequent valorization. On the one hand, biological conversion of sugars derived from hemicellulose can be employed for the production of biofuel (ethanol) or chemicals such as 2,3-butadiene, xylitol and lactic acid. On the other hand, the chemical transformation of these sugars produces furfural, 5-hydroxyfurfural and levulinic acid, which must be considered very important starting blocks for the synthesis of organic derivatives.

“…Therefore, the sum of the number of documents in these categories is above the total number of documents, and a similar result can be found in percentages, with results above 100%. The existence of a reduced number of countries that dominate the publication of scientific documents was expected, as this pattern is very common in most scientific fields [51][52][53], including civil engineering [54,55]. The top 10 countries in Table 2 produced more than 85% of the total number of documents.…”

Research Trends in Pavement Management during the First Years of the 21st Century: A Bibliometric Analysis during the 2000–2013 Period

et al. 2018

A bibliometric analysis based on Scopus database was carried out to identify the global research trends related to pavement management area from 2000 to 2013, and to improve the understanding of the research topics in that period. The results reveal two stable periods of annual publications, from 2000 to 2002 with an average rate of 27, and from 2003 to 2010 with a value of 51; and a period with an increasing production rate of 20 publications per year after 2010. According to the document-type distribution, articles and conference papers have almost the same contribution. The most productive country was the United States, followed by Canada and China. The research trend in the field of pavement management could be grouped into three main areas. The first one is related to pavement management systems, which attracted the greatest attention, especially optimization processes with various objectives and lifecycle cost analysis. The second group is about pavement performance modeling, where calibration of mechanical empirical models was largely developed. Lastly, data collection had also occupied several papers, mainly about cracking classification. Sustainability aspects in pavement management became an emergent issue. The trending issues in that period, in these categories, were summarized in the paper.

“…They highly differ in the methodology employed, the examined topics, and the type of PPP considered. Some studies perform only one round of search on one/two databases and consider only one discipline (Wang et al, 2018;Torchia et al, 2015), some perform a review on manually collected documents (van den Hurk, 2018), while others conduct a structured search on articles from different databases and different disciplines (Neto et al, 2016;Cui et al, 2018;Petersen, 2019). Table A1 in the Appendix offers a summary.…”

Public Private Partnership and fiscal illusion: A systematic review

Public-Private Partnerships (PPPs) are mostly presented as a means to introduce efficient procurement methods and better value for money to taxpayers. However, the complexity of the PPP mechanism, their lack of transparency, accounting rules and implicit liabilities make it often impossible to perceive the amount of public expenditure involved and the long-run impact on taxpayers, providing room for fiscal illusion, i.e., the illusion that PPPs are much less expensive than traditional public investments. This psaper, thanks to a systematic review of the literature on the EU countries experience, tries to unveil the sources of this illusion by looking at the reasons behind the PPPs’ choice, their real costs, and the sources of fiscal risks. The literature suggests that PPPs are more costly than public funding, especially when contingent liabilities are not taken into account, and are employed as mechanisms to circumvent budgetary restrictions and to spend off-balance. The paper concludes that the public sector should share more risks with private sectors by reducing the amount of guarantees, and should prevent governments from operating through a sleight of hand that deflects attention away from off-balance financing, by applying a neutral fiscal recording system.
