Behavioural and neurochemical effects after repeated administration of N-ethylpentylone (ephylone) in mice
2022
N-ethyl-pentylone (NEP), also known as "ephylone" and N-ethylnorpentylone, has been identified as one of the most recent novel psychostimulants to emerge into the illicit drug market and it has been associated with some intoxications and even fatalities. However, little is known about the consequences of its repeated consumption as well as the role of the monoaminergic system in such consequences. Thus, the aim of our study was to investigate the neurochemical profile and the behavioural effects after both acute and repeated NEP exposure. Male OF1 mice were acutely (1, 3, 10 mg/kg, i.p.) or repeatedly (1, 3, 10 mg/kg, i.p., 5 days, twice/day) exposed to NEP, and anxiety-like behaviour, aggr…
In-situ Mössbauer Spectroscopy with MIMOS II at Rio Tinto, Spain
2010
The Rio Tinto, located in southwest Spain, exhibits a nearly constant, acidic pHvalue along its course. Due to the formation of sulfate minerals, Rio Tinto is considered a potential analogue site for sulfate-rich regions on Mars, in particular at the landing site of the Mars Exploration Rover Opportunity, where the ferric sulfate mineral jarosite was identified with Opportunity's Mössbauer spectrometer. Primary and secondary mineralogy was investigated in situ with portable Raman and Mössbauer spectrometers at four different Rio Tinto sampling sites. The two techniques analyse different sample portions due to their specific field of view and sampling depth and provide complementar…
Performance and energy optimisation in CPUs through fuzzy knowledge representation
2019
Abstract This paper presents an automatic design space exploration using processor design knowledge for the multi-objective optimisation of a superscalar microarchitecture enhanced with selective load value prediction (SLVP). We introduced new important SLVP parameters and determined their influence regarding performance, energy consumption, and thermal dissipation. We significantly enlarged initial processor design knowledge expressed through fuzzy rules and we analysed its role in the process of automatic design space exploration. The proposed fuzzy rules improve the diversity and quality of solutions, and the convergence speed of the design space exploration process. Experiments show tha…
Entrevista semiestructurada para la exploración de la violencia sexual sobre las mujeres en la relación de la pareja (EVS)
2016
La violencia sexual en el ámbito de la relación de pareja es un problema grave experimentado por un alto número de mujeres. Sin embargo, es difícil su detección por la ausencia de reconocimiento social. Este tipo de violencia con frecuencia se da ligado a otras formas de maltrato, no obstante observamos que diferentes protocolos de entrevista publicados para explorarla, no la evalúan o lo hacen de forma superficial. Esto se suma al hecho de que algunas de las mujeres que lo sufren no son conscientes del maltrato, ni de la gravedad e impacto real que tiene sobre ellas. Por todo ello, nuestro objetivo es proponer una herramienta de recogida de información sobre la violencia sexual en la parej…
Lucian, a new Odysseus? : role and issue of a Homeric character in the work of Lucian of Samosata
2015
The aim of our thesis, which comes within the scope of considering the process of rewriting classic texts in the time period of the second sophistic, is to study the unique importance of Odysseus in the writings of Lucian of Samosata. At first, Odysseus is distinguished from Achilles, a character more monolithic who, even in Homer’s works is constructed in contrast to Odysseus. Moreover, from an isolated quote to intricate references, scattered to create echoes between works seemingly very different, the context in which Odysseus appears is more elaborate and subtler than that of Achilles. Hence, studying and comparing references to both heroes is sufficient to imply Odysseus’ primacy, asso…
Top Management Team Diversity and Ambidexterity: The Contingent Role of Shared Responsibility and CEO Cognitive Trust
2017
Earlier research has suggested that diversity is a double-edged sword when achieving organizational ambidexterity. While it may contribute to the development of new combinations of exploration and exploitation, it may also lead to disagreements and potential conflict within top management teams (TMTs). To improve our understanding of the effectiveness of diversity in ambidextrous organizations, we develop a synergistic perspective on TMT diversity and examine how two types of diversity – functional and age diversity – affect the achievement of organizational ambidexterity. We also identify shared responsibility and CEO cognitive trust as important contingencies that may complement the effec…
EXPLORATION, EXPLOITATION AND INCENTIVES TO INNOVATE: THE DISCIPLINING ROLE OF DEBT
2014
Extant research suggests that when compared to equity, debt financing is less conducive to innovation activities. In this paper we challenge this view by suggesting that although equity sustains innovation by allowing risk-taking and experimentation, it may also encourage the pursuit of exploration at the expense of exploitation. Under these circumstances, the stricter governance associated with debt becomes important as it stimulates managers to shift resources towards exploitation in order to mitigate risk and improve short-term pay-offs. In support of these arguments our empirical analysis shows that, while leverage has a negative impact on standard measures of innovation quantity and qu…
Software Framework for Hyperspectral Data Exploration and Processing in MATLAB
2017
This paper presents a user introduction and a general overview of the MATLAB software package hsicube developed by the author for simplifying the data manipulation and visualization tasks often encountered in hyperspectral analysis work, and the design principles and software development methods used by the author. The framework implements methods for slicing, masking, visualization and application of existing functions to hyperspectral data cubes without the need to use explicit indexing or reshaping, as well as enabling expressive syntax for combining these operations on the command line for highly efficient data analysis workflows. It also includes utilities for interfacing with existing…
Entering an emotional minefield: professionals’ experiences with facilitators to address abuse in child interviews
2019
Background Extensive research documents that child abuse is widespread and that it has detrimental effects on victims’ physical, psychological and social well-being. Efforts to help abused children by removing stressors and administering restorative care can reverse these negative effects, but the evidence suggests that professionals often fail to expose child abuse. This study aims to generate insight into professionals’ experiences with facilitators in handling the challenges of addressing abuse in child interviews. We expect that this knowledge can improve interventions that qualify professionals in the identification, protection and care of abused children. Methods Within the qualitativ…
''Active Collisions in Altered Gravity Reveal Eye-Hand Coordination Strategies''
2012
White, Olivier | Lefevre, Philippe | Wing, Alan M. | Bracewell, R. Martyn | Thonnard, Jean-Louis; International audience; ''Most object manipulation tasks involve a series of actions demarcated by mechanical contact events, and gaze is usually directed to the locations of these events as the task unfolds. Typically, gaze foveates the target 200 ms in advance of the contact. This strategy improves manual accuracy through visual feedback and the use of gaze-related signals to guide the hand/ object. Many studies have investigated eye-hand coordination in experimental and natural tasks; most of them highlighted a strong link between eye movements and hand or object kinematics. In this experime…
