Influence of cultivation techniques and use of two nutritive solution with different electrical conductivity on the production and quality of cucumbe…
2009
The most suitable techniques and use of F1 hybrids enable greenhouse production to achieve high yields, with crops all year round. In Sicily, greenhouse production of cucumber is for fresh use (slicers), producing large fruit. The cultivation technique most suited to greenhouses is the vertical single stem. However, an innovative technique being proposed is of cultivation on a trellis, eliminating lower branches, and training the remaining branches upwards (vertical shoot positioning, VSP). Cucumbers in the south of Italy are grown as the main crop or as a catch crop between 2 main crops. The crop should be rotated on the same soil only after 3-4 years with another crop, unless the land is …
The impact of coffee on health
2013
Abstract Objective Coffee is a beverage used worldwide. It includes a wide array of components that can have potential implication on health. We have reviewed publications on the impact of coffee on a series of health outcomes. Methods Articles published between January 1990 and December 2012 were selected after crossing coffee or caffeine with a list of keywords representative of the most relevant health areas potentially affected by coffee intake. Results Caffeine, chlorogenic acids and diterpenes are important components of coffee. Tolerance often acts as a modulator of the biological actions of coffee. There is a significant impact of coffee on the cardiovascular system, and on the meta…
The Role of e-Tutor Competencies in Postgraduate e-Learning Courses: Spotlight on Emotion Management
2021
The role of e-learning in the existing and challenging educational era is crucial. However, it is necessary to overcome some drawbacks such as feelings of isolation and a lack of emotional contact. In this sense, emotion management is a key driver of student satisfaction in e-learning, which is significantly related to students’ motivation, learning, cognitive strategies, self-regulation, and personality antecedents in the classroom. This article examines an online postgraduate course in financial statements auditing, describing the resources used by the e-tutor to conduct affective tutorials, reduce students’ feelings of isolation, increase student involvement, and achieve success in e-lea…
Social Capital, Human Capital, and Sustainability: A Bibliometric and Visualization Analysis
2018
[EN] Academic interest in social and human capital is growing significantly. Similarly, their relationship with sustainability is increasing, especially compared to sustainability¿s relationship with natural capital and financial and economic capital. Bibliometric and visualization research on these relationships is nonetheless insufficient. This study analyzes the evolution of the literature on natural capital, financial and economic capital, and social and human capital related to sustainability. On the other hand, the study presents a bibliometric analysis on social capital and human capital (SHC) related to sustainability. The article studies 635 references collected from theWeb of Scie…
Representations of Woman’s Body in Prose by Latvian Women Writers
2013
Feminism has been deeply concerned with female body either as something to be rejected in the pursuit of intellectual equality or as something to be reclaimed as the very essence of women. Another alternative, associated with feminist postmodernism, seeks to emphasize the importance and inescapability of embodiment rather as a differential and fluid construct than as a fixed given. Different female body representations are inscribed in Latvian women’s prose from 1960s to 2010. As it was common for Soviet literature, also in prose of Latvian women writers of the period body and sexuality, especially the female one, was left beyond the discussion, mostly figuring as the unspoken. If woman’s b…
PISA y TALIS ¿congruencia o discrepancia?
2016
Las evaluaciones educativas internacionales a gran escala ofrecen información de interés para la comunidad educativa, científica y política. Son muchos los estudios derivados de ellas, tanto a nivel nacional como internacional. Por otra parte, es bien conocida, desde el origen de estas macroevaluaciones, la diversidad de valoraciones que han generado. En este contexto, el objetivo del trabajo que aquí se presenta es estudiar las relaciones entre los resultados de PISA 2012 y los relativos a práctica docente de secundaria de TALIS 2013, tratando de analizar las congruencias o discrepancias entre los resultados de ambas. Se tomaron los datos del estudio TALIS-PISA link. Los análisis realizado…
Levels of cognitive congruence between managers and team members’ perceptions of cooperation at work
2019
Much of the research on the psychological dynamics of performance teams suffers from the following limitations: consideration of only one theoretical framework and analysis of just one perspective (e.g., manager&ndash
Diverse societies are more productive: a lesson from ants
2012
The fitness consequences of animal personalities (also known as behavioural syndromes) have recently been studied in several solitary species. However, the adaptive significance of collective personalities in social insects and especially of behavioural variation among group members remains largely unexplored. Although intracolonial behavioural variation is an important component of division of labour, and as such a key feature for the success of societies, empirical links between behavioural variation and fitness are scarce. We investigated aggression, exploration and brood care behaviour in Temnothorax longispinosus ant colonies. We focused on two distinct aspects: intercolonial variabil…
E-Fairs: a Cyber-Physical System for Aggregation and Economy of Scale in e-Commerce
2018
In recent years, the e-commerce arena has deeply changed because of the advent of new business models and the growing weight of huge global actors like Amazon. Some business models create competition between users, and the product price tends to rise (e.g., online auctions); other models, including group-buying, make users cooperate, and the price tends to go down. The present study extends the group-buying model and proposes a cyber-physical system called e-fair, in which both sellers and buyers are grouped to negotiate on a specific product or service. E-fairs minimize the global purchase price and the shipping resources respectively with the aggregation of demand and supply as well as or…
An Approach to the Quality of Drinking Water as a Matter of Multicriterial Decision
2021
The aim of the present paper is to approach the matter of water quality by resorting to the metod of multicriterial mathematical programming. MicrosoftExcel enables the simulation of a mathematical model. Furthermore, we have also created a file in the C++ software, in view of the simulation process, applicable to numberless properties of water quality. The case study presents the simulation of a multicriterial analysis of water quality in Sibiu county. This particular study shows the means of obtaining more information about water quality, subsequent to the analysis of its characteristics resorting to statistical analysis-specific software, e.g. SPSS 16 software. Given the increase of drin…
