Abstract. This paper presents and applies an experimental agroforestry accounting system (AAS) to measure the commercial income and capital of hunting activities in a large territorial area.

Abstract. This paper proposes a novel approach for simulating the price of hunting self-consumption by owners in the experimental Agroforestry Accounting System (AAS).

Abstract. We perform two convergent validity tests in a choice experiment applied to public recreation in Spanish stone pine and cork oak forests. Results show convergent validity between a choice and a ranking recoded as a choice format in an experiment with three alternatives plus status quo.

Abstract. Context. Driven hunts exemplify the most representative form of big-game hunting in southern Europe.
Aims. We analysed hunter preferences for driven hunts and the marginal willingness to pay for their characteristics.
Methods. We conducted a discrete-choice experiment for driven hunts, taking into account the number of deer that could
be hunted, the possibility of free-range wild-boar hunting, the presence of trophies, and other characteristics of driven hunts, such as congestion and travel time.

Abstract. This study on research collaboration (RC) is an attempt to estimate the degree of internationalization of academic institutions and regions. Furthermore potential influences of RC on excellence initiatives of modern universities are investigated relying on source data obtained from SCImago Institutions Rankings. A positive correlation exists between the degree of collaboration and the normalized impact. However, in contrast to output the normalized impact increase progression is non-linear and fluctuating.

Abstract. The SCImago Institutions Rankings (SIR) World Reports are published annually. These reports contain an international ranking of more than 2000 research institutions and organizations. The indicator values are based on publication and citation data from Scopus (Elsevier) for research-devoted institutions with at least 100 papers published within the year under study.

Abstract. Although Spain is ranked 10th in scientific production, it is 22nd in impact. The distribution of scientific production across the 17 Spanish regions is analyzed. Madrid and Catalonia account for 49% of total production and for 58% of excellence as reflected in impact, defined as publications within the 10% most cited worldwide.

Abstract
Purpose
Gene term variation is a shortcoming in text‐mining applications based on biomedical literature‐based knowledge discovery. The purpose of this paper is to propose a technique for normalizing gene names in biomedical literature.

Abstract. This study examines world scientific production on renewable energy, sustainability and the environment on the basis of bibliometric indicators (scientific production, percentage variation of production, average cites per document, normalized impact, impact, etc.) for the period 2003–08. The analysis is made by country, by research institution, and by scientific journal, using the Scopus (Elsevier) database of scientific literature.

Abstract. A new size-independent indicator of scientific journal prestige, the SJR2 indicator, is proposed. This indicator takes into account not only the prestige of the citing scientific journal but also its closeness to the cited journal using the cosine of the angle between the vectors of the two journals’ cocitation profiles. To eliminate the size effect, the accumulated prestige is divided by the fraction of the journal's citable documents, thus eliminating the decreasing tendency of this type of indicator and giving meaning to the scores.
