Dissecting the factors controlling seed development in the model legume Medicago truncatula
2012
Legumes are not only indispensible for sustainable agriculture but are also a rich source of protein in food and feed for humans and animals, respectively. However, major proteins stored in legume seeds are poor in sulfur-containing amino acids, and may be accompanied by anti-nutritional factors causing low protein digestibility problems. In this regard, Medicago truncatula serves as a model legume to study legume seed development especially the phase of seed storage protein accumulation. As developing legume seeds are complex structures, a thorough knowledge of the morphogenesis of the seed and the characterization of regulatory mechanisms underlying the embryo development and seed filling…
A Split-Window Algorithm for Estimating LST From Meteosat 9 Data: Test and Comparison With Data and MODIS LSTs
2009
The main purpose of this letter is to give an operational algorithm for retrieving the land surface temperature (LST) using the Spinning Enhanced Visible and Infrared Imager data onboard the Meteosat Second Generation (MSG2) satellite. The algorithm is a split-window method using the two thermal infrared channels IR10.8 and IR12.0. The MODTRAN 4.0 code was used to obtain numerical coefficients of the algorithm proposed. The results show that for viewing angles lower than 50deg the algorithm is capable of producing LST with a standard deviation of 0.7 K and a root-mean-square error (rmse) of 1.3 K. The algorithm has been applied to a series of MSG2 images obtained from an MSG antenna system …
Understanding the Impact of Opinion Leaders’ Characteristics on Online Group Knowledge-Sharing Engagement from In-Group and Out-Group Perspectives: E…
2019
Opinion leaders often play key roles in online knowledge-sharing communities, which has intrigued a lot of researchers and practitioners worldwide. However, it is not clear how various characteristics of opinion leaders may affect different online groups&rsquo
Impact of the "salary scholarship" impact profile and student achievement.
2013
In Spain, within the framework of the Strategy 2015, the implementation of scholarships, grants and wages especially adapted to the new situation of the European Higher Education, intended to ensure access to university education to those most disadvantaged social groups economically. This research makes an ex post facto, descriptive-comparative aimed at assessing the impact of the grant salary, as an economic factor, on equity, access and academic performance in the first year of college. The study was conducted with a total of 10,394 new students in the 2010-11 cohort at the University of Barcelona, from the database from the institution itself. A total of 642 students agreed to grant sal…

The Inclusion of Socially Irresponsible Companies in Sustainable Stock Indices
2019
Social rating agencies implement complex filters to identify the companies with the best sustainable and social performance and help investors select the companies for their sustainable portfolios. This study analysed whether companies that are defined as ethical, sustainable and socially responsible by those agencies actually deserve this label. More specifically, the inclusion in the prestigious Dow Jones Sustainability Index (DJSI) World of companies that have been involved in controversies according to the Thomson Reuters Eikon database was studied. The results show that the inclusion of irresponsible companies in the DJSI Index is a fact. This outcome is in line with previous studies t…
Evaluating the Eco-Efficiency of Wastewater Treatment Plants: Comparison of Optimistic and Pessimistic Approaches
2020
The assessment of wastewater treatment plant (WWTP) performance has gained the interest of water utilities and water regulators. Eco-efficiency has been identified as a powerful indicator, as it integrates economic and environmental variables into a single index. Most previous studies have employed traditional data envelopment analysis (DEA) for the evaluation of WWTP eco-efficiency. However, DEA allows the selection of input and output weights for individual WWTPs for the calculation of eco-efficiency scores. To overcome this limitation, we employed the double-frontier and common set of weights methods to evaluate the eco-efficiency of a sample of 30 WWTPs in Spain. The WWTPs were ranked b…

Abstract This paper presents an index that measures reviewer contribution to editorial processes of scholarly journals. Following a metaphor of ranking algorithms in sports tournaments, we created an index that considers reviewers on different context-specific dimensions, i.e., report delivery time, the length of the report and the alignment of recommendations to editorial decisions. To test the index, we used a dataset of peer review in a multi-disciplinary journal, including 544 reviewers on 606 submissions in six years. Although limited by sample size, the test showed that the index identifies outstanding contributors and weak performing reviewers efficiently. Our index is flexible, cont…
