Exploring Postgraduate Socioeconomics Programs in Spanish-Speaking Countries

2019

Resumen En los últimos años las actividades sin fines de lucro han sido promovidas como un mecanismo alternativo para el desarrollo en el contexto de la situación económica mundial. Sin embargo, a pesar de sus potencialidades, esas actividades continúan siendo relativamente poco expandidas y requieren de ampliar los conocimientos sobre ellas. En este sentido la universidad puede convertirse en un generador y transmisor de saberes sobre el tema de economía social. Por esta razón, se plantea desarrollar un análisis de la oferta de programas de posgrado en Economía Social en las instituciones de educación superior latinoamericanas y españolas. El artículo presenta el proceso y los resultados d…

Innovation: transforming hierarchies in South Asia

2014

This special issue examines innovation as social change in South Asia. From an anthropological micro perspective, innovation is moulded by social systems of value and hierarchy and simultaneously potentially transforms them. The articles in this special issue examine a number of innovations in South Asian contexts: the printing press's changing technology and its intersections with communal and language ideologies in India (Peterson); mobile telephony, gender, and kinship in West Bengal (Tenhunen); microcredit and its relationship with social capital in Bangladesh (Uddin); imbalanced sex ratios and the future of marriage payments in north-western India (Jeffery); and how alternative dispute…

Role of alternative food networks in Sicilian farms

2014

Today the short supply chain can be carried out through several typologies which are called as alternative food networks (AFNs). In fact, according to some studies, it is an 'alternative' response to the dominant agro-food system, which offers the possibility to produce food products through supply chains that are opposed to long, complex and rationally organised industrial chains. In the last years many European farmers adopted short supply chain to commercialise their agro-food products and Italy is one of the EU members in which AFNs are developed, thanks to its numerous typical an local products. The aim of this paper has been to analyse the role that AFNs play in Sicilian farms and how…

Un approccio progettuale per la rigenerazione sostenibile

2020

This paper describes the methodology of research and analy- sis that have been adopted in order to develop the targets of the project, along with the design proposal. A literature review about urban regeneration ad its best practices and a deep study of the various features and peculiarities of the area has been conducted. Such a study guided the definition of the criteria that must be ap- plied to develop the project. The proposal of urban regeneration aims to retrain the whole di- strict by retrofitting ENPAM’s buildings and industrial sheds by the railway as well as redesigning the public spaces and the green areas. The remainder of this paper is organized as follows. The first section o…

A Multisite Preregistered Paradigmatic Test of the Ego-Depletion Effect

2021

We conducted a preregistered multilaboratory project ( k = 36; N = 3,531) to assess the size and robustness of ego-depletion effects using a novel replication method, termed the paradigmatic replication approach. Each laboratory implemented one of two procedures that was intended to manipulate self-control and tested performance on a subsequent measure of self-control. Confirmatory tests found a nonsignificant result ( d = 0.06). Confirmatory Bayesian meta-analyses using an informed-prior hypothesis (δ = 0.30, SD = 0.15) found that the data were 4 times more likely under the null than the alternative hypothesis. Hence, preregistered analyses did not find evidence for a depletion effect. Ex…

New Alkenylresorcinols with Cytotoxic and Antimicrobial Activities from the Leaves of Embelia schimperi.

2020

AbstractA phytochemical study of the methanol extract of the leaves of Embelia schimperi resulted in the isolation of three new alkenylresorcinols, 1 – 3, together with the known analogs 4 – 7. Their structures were established by a combination of spectroscopic techniques. Compounds 1 – 7 exhibited moderate cytotoxic activity against human cervical cancer cells HeLa-S3 and more pronounced antimicrobial properties towards bacteria and filamentous fungi. The present study falls into an ongoing research project on the characterization of bioactive phenolic lipids from plants of the family Primulaceae.

The RNA-binding protein ELAV regulates Hox RNA processing, expression and function within the Drosophila nervous system

2014

The regulated head-to-tail expression of Hox genes provides a coordinate system for the activation of specific programmes of cell differentiation according to axial level. Recent work indicates that Hox expression can be regulated via RNA processing but the underlying mechanisms and biological significance of this form of regulation remain poorly understood. Here we explore these issues within the developing Drosophila central nervous system (CNS). We show that the pan-neural RNA-binding protein (RBP) ELAV (Hu antigen) regulates the RNA processing patterns of the Hox gene Ultrabithorax (Ubx) within the embryonic CNS. Using a combination of biochemical, genetic and imaging approaches we demo…

Modulation of Diabetes by Natural Products and Medicinal Plants via Incretins

2019

Incretins are metabolic hormones released after a meal that increase insulin secretion from pancreatic β-cells. The two main incretins are the intestinal peptides glucagon-like peptide-1 and glucose-dependent insulinotropic polypeptide. Both induce a decrease in glycemia, slow down the absorption of nutrients, and are inactivated by the enzyme dipeptidyl peptidase-4. Recently, incretin-based therapies have become a useful tool to treat diabetic patients, and different studies have focused on the identification of glucagon-like peptide-1 receptor agonists, including those of natural origin. This review focuses on the new findings of medicinal plants and natural products as possible active ag…
