What makes a citrus farmer go 'organic'? Empirical evidence from Spanish citrus farming
2012
Organic farming is increasing its share of total world food output and receiving grow-ing support from policymakers concerned with agricultural sustainability issues. This paper studies the characteristics of citrus farmers in the Spanish region of Valencia that affect their probability of becoming organic farmers. A fair understanding of these characteristics may help policymakers improve the design of agricultural policies aimed at supporting organic citrus practices. As regards the methodology, a probit model is estimated with information from a sample of conventional and organic citrus farmers obtained from a survey designed for a larger research project aimed at analysing Valencian cit…
La producción española en Tesis Doctorales sobre orientación en la Base de Datos TESEO (2001-2012)
2013
The objective of this research is to analyse the scientific production in PhD Thesis about guidance in Spain from 2001 to 2012. The data have been recollected on the TESEO database belonging to the Ministry of Education, Culture and Sport. It has realized a content analysis of the titles, keywords and abstracts and it has assessed of them their productivity, the general and methodological features and the subjects that have been studied. It has been obtained ninety PhD Thesis in relation to the field of guidance over the last ten years that have studied mainly curriculum and career development. El objetivo de este estudio es analizar la producción científica en Tesis Doctorales sobre orient…
Latvijas Universitātes kultūrvēsturiskais mantojums izstādēs: Bibliotēkas versija
2020
Bibliotēka kā atmiņas institūcija ir atbildīga par savas ‘jumta organizācijas’ kultūrvēsturiskā mantojuma saglabāšanu un pieejamību sabiedrībai. Latvijas Universitātes Bibliotēkas rūpju lokā ir ne tikai LU informacionālais nodrošinājums ikdienā, bet arī pašas Universitātes intelektuālais, zinātniskais un kultūras mantojums ilglaicīgā aspektā. Ar iespējami pilnīgāku ar Universitāti, tās darbību un cilvēkiem saistītu materiālu uzkrāšanu ir par maz, tie ir arī jāapkopo, jāsistematizē, jāapstrādā, jādara pieejami un visbeidzot - jāpopularizē, lai informācija nonāktu apritē un pavērtu iespējas tā tālākai izmantošanai, izpētei, zināšanai, nevis iegultu putekļos. Bibliotēkas devums, kāds pirms pār…
Différents modes de production
2012
Les productions générées par les exploitations agricoles sont organisées en système de production qui désigne « l’ensemble structuré des facteurs de production combinés entre eux pour assurer une production végétale et/ou animale en vue de satisfaire les objectifs de l’exploitant agricole ». Les systèmes de production sont souvent décrits par les OTEX (orientations technico-économiques des exploitations) sur une base économique de classification, mais il existe égalementdes descriptions fonctionnelles fréquemment utilisées parles instituts techniques sur la base des facteurs de production et de leur combinaison. Dans les exploitations françaises, la production d’herbivores (bovins, ovins, c…

Cueva de El Toro (Antequera, Malaga-Spain): a Neolithic stockbreeding community in the Andalusian region, between the 6th and 3th millennia BC
2004
The occupation evidence shown by the cave El Toro, is that of a unique stockbreeding community in the Andalusian region. The calibrated dates for this occupation period go from the second quarter of the sixth millennium up to the second millennium BP. There is also evidence of occasional occupation throughout later millennia up to the Hispano-Muslim period. The nature of thisoccupation is determined by the close link between the cave and the community which occupied it, both continuously and periodically. Throughout the occupation levels, the community's skillful control of technical processesand its remarkable knowledge on how to transform local primary resources, have shown that this comm…
Individual- and group-level sex ratios under local mate competition : consequences of infanticide and reproductive dominance
2023
Extremely female-biased sex ratios of parasitoid wasps in multiple-foundress groups challenges evolutionary theory which predicts diminishing bias as foundress numbers increase. Recent theory based on foundress cooperation has achieved qualitative rather than quantitative success in explaining bias among parasitoids in the genus Sclerodermus. Here, we develop an explanation, expanding the theory of local mate competition, based on the observation that male production seems dominated by some foundresses within groups. Two sex ratio effects arise from such reproductive dominance: an immediate effect via suppression of male production, and a long-term evolutionary response to reproductive skew…
Conventional Theory’s Relevance: Evidence from Japan
2019
Abstract The formidable surge in the volume of international trade after 1960 stimulated surveys designed to ascertain to what degree the commercial flows among nations reflected the structure of their economies, in other words, how tight was the correlation between international exchanges and the specific attributes of participating nations. In fact, scholars were keen to test the relevance of the conventional Heckscher-Ohlin theory, that is, to what extent did nations’ exports reflect their endowment with factors of production, more specifically, whether their exports used their abundant factors intensively. I try to show that, although most of the tests reached their purpose in that they…
Production, oxidation traits and health of dairy ewes fed diets supplemented with fungus myceliated grains.
2019
Mushrooms contain many bioactive compounds, mainly poly- and oligosaccharides, known to have benefits for human health. Polysaccharides from mushrooms exhibited immunomodulatory, antibacterial, antiviral, and antifungal properties, as well as antitumor activity. Furthermore, some mushrooms showed to have potent antioxidant properties due to the presence of phenolic acids, flavonoids, polysaccharides, carotenoids, ascorbic acid, and tocopherols. These beneficial properties of mushrooms bioactive compounds indicate their potential use as performance-enhancing natural feed additives for livestock animals. In this regard, the use of mushrooms and mushroom-derived products has largely been inves…
Reproduction of Baltic cod, Gadus morhua (Actinopterygii: Gadiformes: Gadidae), in the Gotland Basin: Causes of annual variability
2015
Background. The Gotland Basin spawning ground is one of three main spawning areas of Baltic cod, Gadus morhua Linnaeus, 1758. The threshold water parameters for cod development are the salinity exceeding 11‰ and the oxygen level above 2 mL· L–1. Such conditions are only present when the 11‰ isohaline is above the 2 mL· L–1 isooxygen. In such situation the water volume between the isolines is called the “suitable reproduction volume”. When the position of the isolines is reversed, the salinity and the oxygen level of the water layer demarcated by them are below the required thresholds and as such the water is unsuitable for the cod development. We refer to it as the “unsuitable reproduction …
