The need for internships and school practices as a method of bridging the gap between education and industry in Romania
2017
Abstract This paper presents the current situation of school practice and internships as ways of reducing the gap between the labor market and education. In the first part, there is highlighted the current situation of Romania comparing with other European countries when it comes about graduates finding a job in their field of studies. Among the biggest issues encountered by a young graduate we see that "Lack of experience” play a big role in not finding a proper job in our country after graduation. So the need to reduce this problem is vital in order to ease finding a job in the studies areas for graduates. A list of advantages is presented to encourage internships/school practice among th…
Vanadium pentoxide nanoparticles mimic vanadium haloperoxidases and thwart biofilm formation
2012
Marine biofouling—the colonization of small marine microorganisms on surfaces that are directly exposed to seawater, such as ships' hulls—is an expensive problem that is currently without an environmentally compatible solution1. Biofouling leads to increased hydrodynamic drag, which, in turn, causes increased fuel consumption and greenhouse gas emissions. Tributyltin-free antifouling coatings and paints1, 2, 3, 4 based on metal complexes or biocides have been shown to efficiently prevent marine biofouling. However, these materials can damage5 the environment through metal leaching (for example, of copper and zinc)6 and bacteria resistance7. Here, we show that vanadium pentoxide nanowires ac…
A major shift in Late Bronze Age metalwork production around 900 BC
2023
Our traditional chronology systems hardly ever reflect cultural changes accurately and may even mask real moments of discontinuity. This is particularly true for the second part of the Late Bronze Age Urnfield Period where a radical change in iconography can actually be noticed around 900 BC. Within a very short period, the famous solar bird-boat iconography, which had widely developed over centuries and given rise to the elaborate and sophisticated ornamentation known on solid hilted swords from the 11th/10th century, takes a back seat and we can see a single new symbol coming to the fore, concentrating figurative representation in form of a singular vase-shaped build (Wirth S. 2021, 652-6…
Transmission patterns in the production of Bronze Age solid- hilted swords
2023
Bronze Age swords with a bronze hilt were a highly specialised production. Casting hilts and blades and fixing them to each other require lots of precision and very specific skills. We hardly know anything about the production organisation as moulds are extremely rare, preventing us from locating workshops. However, studying swords themselves using X-ray imaging techniques allows us to reconstruct a part of the chaîne opératoire and gain insight into some aspects of the production processes. We identify three periods in the production of solid-hilted swords at the European scale:1. Experimental phase (1800-1450 BC): small-scaled productions by multiple workshops experimenting various ways o…
Production et circulation des épées à poignée métallique de l'âge du Bronze en Europe occidentale
2022
Several regional syntheses have been published on Bronze Age solid-hilted swords, but none for France and the Benelux countries. This dissertation aims first at filling this gap by listing the swords from this region. By adding data from these pre-existing studies, it is possible to study the distribution of solid-hilted swords on a European scale. The building of an inventory is an essential condition to study the diffusion of these weapons over long distances. This must come along with models to characterise the organisation of the swords production and the ways they spread out. It requires us to question the status of the craftsmen, their organisation and their location. One of the first…
Per un’educazione universale. La via del Buddhismo nelle società post-secolari
2018
The paper examines Buddhism as a religion that suggests to the post-modern and post-secular West a new, inclusive, non-violent and ecological education. It proposes an universal education that responds to the request of religiosity of our societies. Buddhism is investigated as a millennial pedagogy, in which the path of spiritual growth coincides with a path of self-education that is articulated through an interior and social education. The center of the Buddhist doctrine is the meditation (dhyan), that leads the disciple, with the support of a master and the community, for a rebirth that, declaring him as the author of his own realization, leads him to establish empathic relationship with …
Les commissions de quartier à l’heure de l’engagement écocitoyen, à Dijon : entre communication stratégique publique locale et construction d’un espa…
2018
This doctoral thesis in Information and Communication Science explores the question of eco-citizen commitment in the neighborhood commissions of Dijon. Many academic or more popular publications in different fields of research (Information and Communication Science, social and environmental psychology, political science, law, philosophy, ecology, etc.) have addressed this issue in recent years. Once the actors of the question had been defined (the inhabitants, elected officials, technicians, representatives of structures and associations, etc.), it was possible to study different instances of participatory democracy in Dijon. The following question ensued : "How are the neighborhood commiss…
New evidence on accelerator performance based on funding and location
2020
Seed accelerators (SAs) appear as a more advanced version of business incubators. These for-profit organizations in exchange of equity, help setting new start-ups by providing mentoring and funding during its first months. Due to their emergent nature, the impact and expectations of SAs remains largely unknown. Therefore, the purpose of this study is to throw new light on this field by empirically assessing for the first time the performance and prospects of these organizations through a survey of 116 SAs.,A model based on the Business Incubators literature is built with four categories covering size, location, age and profitability variables, leading to two hypotheses to be tested empirica…
Evidence for a modulatory role of cannabinoids on the excitatory NANC neurotransmission in mouse colon
2007
Abstract It is well accepted that endogenous cannabinoids and CB1 receptors are involved in the regulation of smooth muscle contractility and intestinal motility, through a mechanism mainly related to reduction of acetylcholine release from cholinergic nerve endings. Because, few data exist on a possible modulatory action of the cannabinoid agents on the non-adrenergic non-cholinergic (NANC) excitatory and inhibitory neurotransmission, the aim of the present study was to investigate the effects of cannabinoid drugs on the NANC responses elicited by electrical field stimulation (EFS) in the circular muscle of mouse proximal colon. Colonic contractions were monitored as changes in endoluminal…
Adolescents with Neuropsychiatric Disorders during the COVID-19 Pandemic: Focus on Emotional Well-Being and Parental Stress
2022
(1) Introduction: The aim of our research was to explore emotional/behavioral changes in adolescents with neuropsychiatric conditions during the COVID-19 pandemic, and parental stress levels through a standardized assessment, comparing the data collected before and during the first months of lockdown. Moreover, an additional goal was to detect a possible relationship between emotional/behavioural symptoms of adolescents and the stress levels of their parents. (2) Methods: We enrolled 178 Italian adolescents aged between 12–18 that were referred to the Child Neuropsychiatry Unit of the University Hospital of Salerno with different neuropsychiatric diagnoses. Two standardized questionnaires w…
