Internal vs. external R&D teams: Evidences from the Italian wine industry

2021

R&D teams' internationalization attracts interests from different research-streams. However, the decision on what type of R&D structure is more convenient to invest in may differ, based on several factors, such as risk-taking propensity and internal resource availability. With an aim to enrich the extant literature and to provide practical insights for managers working in the wine industry, this case study explores the determinants of an Italian family-owned winery that attempts to keep a balance between its internal and external R&D teams' decision, using an integrated theoretical framework based on the transaction costs and the resource-based view theory. The optimal R&D s…

Manifesto for the future of work and organizational psychology

2019

© 2019, © 2019 The Author(s). Published by Informa UK Limited, trading as Taylor & Francis Group. This manifesto presents 10 recommendations for a sustainable future for the field of Work and Organizational Psychology. The manifesto is the result of an emerging movement around the Future of WOP (see www.futureofwop.com), which aims to bring together WOP-scholars committed to actively contribute to building a better future for our field. Our recommendations are intended to support both individuals and collectives to become actively engaged in co-creating the future of WOP together with us. Therefore, this manifesto is open and never “finished.” It should continuously evolve, based on an ongo…

Functional A Posteriori Error Estimates for Time-Periodic Parabolic Optimal Control Problems

2015

This article is devoted to the a posteriori error analysis of multiharmonic finite element approximations to distributed optimal control problems with time-periodic state equations of parabolic type. We derive a posteriori estimates of the functional type, which are easily computable and provide guaranteed upper bounds for the state and co-state errors as well as for the cost functional. These theoretical results are confirmed by several numerical tests that show high efficiency of the a posteriori error bounds. peerReviewed

Tower sets and other configurations with the Cohen-Macaulay property

2014

Abstract Some well-known arithmetically Cohen–Macaulay configurations of linear varieties in P r as k-configurations, partial intersections and star configurations are generalized by introducing tower schemes. Tower schemes are reduced schemes that are a finite union of linear varieties whose support set is a suitable finite subset of Z + c called tower set. We prove that the tower schemes are arithmetically Cohen–Macaulay and we compute their Hilbert function in terms of their support. Afterwards, since even in codimension 2 not every arithmetically Cohen–Macaulay squarefree monomial ideal is the ideal of a tower scheme, we slightly extend this notion by defining generalized tower schemes …

Application of deep convolutional neural networks for the detection of anthracnose in olives using VIS/NIR hyperspectral images

2021

Abstract Anthracnose is one of the primary diseases that affect olive production before and after harvest, causing severe damage and economic losses. The objective of this work is to detect this disease in the early stages, using hyperspectral images and advanced modelling techniques of Deep Learning (DL) and convolutional neural networks (CNN). The olives were artificially inoculated with the fungus. Hyperspectral images (450–1050 nm) of each olive were acquired until visual symptoms of the disease were observed, in some cases up to 9 days. The olives were classified into two classes: control, inoculated with water, and fungi composed of olives inoculated with the fungus. The ResNet101 arc…

Indirect assessment of an interpretation bias in humans: Neurophysiological and behavioral correlates

2013

Affective state can influence cognition leading to biased information processing, interpretation, attention, and memory. Such bias has been reported to be essential for the onset and maintenance of different psychopathologies, particularly affective disorders. However, empirical evidence has been very heterogeneous and little is known about the neurophysiological mechanisms underlying cognitive bias and its time-course. We therefore investigated the interpretation of ambiguous stimuli as indicators of biased information processing with an ambiguous cue-conditioning paradigm. In an acquisition phase, participants learned to discriminate two tones of different frequency, which acquired emotio…

New tailor-made bio-organoclays for the remediation of olive mill waste water

2013

A systematic study aimed at obtaining new organoclays for the treatment of Olive Mill Waste water (OMW) has been performed. Several organoclays have been prepared by loading different amounts of the biocompatible surfactant Tween20 onto the K10 montmorillonite (MMT). Complementary kinetic and equilibrium studies on the adsorption of the Tween20 onto the MMT have been carried out and the characterization of the new tailor-made bio-materials has been performed by means of the XRD and FT-IR measurements. Finally the prepared bio-organoclays have been successfully applied for the OMW remediation and they proved to be highly effective in decreasing the organic content (OC) to an extent that depe…

COVID-19 and the future of work and organisational psychology

2021

Orientation: The coronavirus disease 2019 (COVID-19) pandemic has caused a ‘coronafication’ of research and academia, including the instrumentalisation of academic research towards the demands of society and governments. Whilst an enormous number of special issues and articles are devoted on the topic, there are few fundamental reflections on how the current pandemic will affect science and work and organisational psychology in the long run.Research purpose: The current overview, written by a group of members of the Future of Work and Organisational Psychology (FOWOP) Movement, focuses on the central issues relating to work and organisational psychology that have emerged as a result of the …

Introduction: real animals on the stage

2018

This special issue explores the role particularly of live animals on the stage, from the early modern era to the present time. The contributions deal with visual and textual representations of performing animals, typologies of animals in the theatre, the hybridization of the drama with the circus, the zoo and the cinema, as well as the semiotic transfer of animal roles from the text to the stage. We seek here to focus on the changing historical fortunes of the four-footed actor and explore the ways that attitudes to the animal affect their dramatic representations and uses. In attempting to relate snapshots of acting animals from their earliest manifestation on the early modern stage, we co…
