Abstract
Alternative fuels for transportation are gaining momentum in the global market. Ethanol has been the most used biofuel as an additive and as a substitute for gasoline in a number of countries. Current technology to produce ethanol based on sugar and starch crops creates price imbalances in the food market and cannot supply a sustainable industry of ethanol in the long term. Second generation technologies based on cellulosebased feedstocks use non‐edible crops and have a positive energy balance. Notwithstanding, they are not yet economic at the industrial level, requiring investment in Research and Development (R&D) to help overcome technological barriers. Many countries recognise the value of collaboration to increase benefits and reduce costs of research, and some of them have in place policy instruments to promote this practice. Given the policy relevance, multidisciplinary characteristics of biofuels, and increasing incentives towards international cooperation, the monitoring of the evolution and patterns of international collaboration in R&D is in place. We map the evolution of the global scientific activity of research on cellulosic ethanol. We carry out a bibliometric analysis by building a publication dataset drawn from the ISI Thompson Science Citation Index database covering the period between 1970 and 2006. We identify the most productive institutions and countries, their historical evolution and interaction patterns.

SPAIN: Catalan parties will seek to break deadlock
The outcome will be significant for the direction of the pro-independence movement as well as the stability of Sanchez’s minority government in Madrid, which ERC has supported.

Abstract
Purpose
This study aims to explore the issue of word of mouth (WOM) about mobile shopping, including activities conducted by consumers using a wireless internet connection to make a purchase. The objective is to ascertain the determinants of m-shoppers’ WOM.
Design/methodology/approach
This study uses a causal model to examine how satisfaction, perceived control, perceived entertainment and subjective norms affect WOM about mobile commerce. The authors treated a sample of 447 Spanish mobile phone buyers and applied different sound theoretical approaches to support the research.
Findings
Shopping experience, control over the process, group influence and satisfaction with mobile purchasing affect subsequent WOM shopping recommendations by innovative and pioneer mobile shoppers. Besides, entertainment, group influence, shopping experience and perceived control influence customer satisfaction in mobile shopping contexts.
Originality/value
This research provides a better understanding of WOM regarding m-shopping and contributes by outlining important variables for recommending WOM regarding m-shopping, which is key in the m-shopping diffusion. To the best of the authors’ knowledge, this is a pioneer study in Europe focusing on these variables for addressing the ways of achieving m-shopper WOM and one of the few addressing WOM in the m-shopping context. This study is based on information collected from real buyers, who are pioneer in m-shopping.

Abstract
Purpose
Relatively little is known about the determinants of the prices of paintings. The purpose of this paper is to analyse the price determinants of the art of Joan Miró, one of the great masters of Modern Art.
Design/methodology/approach
The authors analysed 255 artworks by Miró sold at Sotheby’s and Christie’s between 2003 and 2017, and performed a hedonic price regression to measure the impact of a series of variables on the prices of this artist’s works.
Findings
Miró’s works command higher prices, ceteris paribus, when they were painted on canvas, were sold at Sotheby’s and in New York City or London, were traded during the evening session and depending on the period in which they had been painted, the size of their surface area, the number of words used to describe the respective lot and whether they had appeared in an art book. The prices of Miró’s paintings increased substantially between 2003 and 2008 and then declined, coinciding with the global financial crisis of 2009.
Research limitations/implications
The results were obtained from prices established in art auctions, which represent only one portion of the market.
Originality/value
This is the first exhaustive study carried out on the determinants of the prices of Joan Miró’s works. The artist represents an ideal case due to the large number of his works that have been sold at auctions. As yet, only studies of Pablo Picasso and Andy Warhol have been conducted. Joan Miró has well-defined artistic periods, which also allows us to determine the impact on the price of the works of the period in which it was created. This paper also offers a methodological contribution to parties involved in the art sector (artists, galleries, collectors, investors, museums, etc.).
Objetivo
Se conoce relativamente poco acerca de los determinantes de los precios de las obras de arte de artistas específicos. Este estudio analiza los determinantes de los precios de las pinturas de Joan Miró, uno de los grandes maestros del arte moderno.
Diseño/Metodología/Enfoque
Se analizaron 255 pinturas de Miró que fueron vendidas en Sotheby’s y Christie’s entre 2003 y 2017, y se estimó una regresión hedónica de precios con el objetivo de medir el impacto de una serie de variables en los precios de las obras de este artista.
Hallazgos
Las obras de Miró obtuvieron precios más altos, ceteris paribus, cuando estaban puintadas sobre lienzo, se vendieron en Sotheby’s y en la ciudad de Nueva York o Londres, se subastaron durante la sesión de la noche, y dependiendo del período en que se pintaron, el tamaño de su área, la cantidad de palabras utilizadas para describir el lote respectivo y si habían aparecido en un libro de arte. Los precios de las pinturas de Miró aumentaron sustancialmente entre 2003 y 2008 y luego disminuyeron, coincidiendo con la crisis financiera mundial de 2009.
Limitaciones de la investigación/implicaciones
Los resultados se obtuvieron a partir de los precios establecidos en las subastas de arte, los cuales representan solo una porción del mercado.
Originalidad/valor
Este es el primer estudio exhaustivo realizado sobre los determinantes de los precios de las obras de Joan Miró. El artista representa un caso ideal debido a la gran cantidad de sus obras que se han vendido en subastas. Hasta el momento, solo se han realizado estudios de Pablo Picasso y Andy Warhol. Joan Miró tiene períodos artísticos bien definidos, lo que también permitió determinar el impacto que en el precio de las obras podía tener el período en que éstas se crearon. Este trabajo también ofrece una contribución metodológica a las partes involucradas en el sector del arte (artistas, galerías, coleccionistas, inversores, museos, etc.).
