Event-related potentials reveal rapid registration of features of infrequent changes during change blindness

2010

Background. Change blindness refers to a failure to detect changes between consecutively presented images separated by, for example, a brief blank screen. As an explanation of change blindness, it has been suggested that our representations of the environment are sparse outside focal attention and even that changed features may not be represented at all. In order to find electrophysiological evidence of neural representations of changed features during change blindness, we recorded event-related potentials (ERPs) in adults in an oddball variant of the change blindness flicker paradigm. Methods. ERPs were recorded when subjects performed a change detection task in which the modified images w…

Imagining a “post-carbon” future? Climate change as represented by media and film industries

2020

This study explores current trends in representing and communicating climate change by media industries. It reviews the current literature on mainstream media narratives of climate change focusing on their naturalization of progress and their techno-optimism (e.g., as regards geoengineering). It provides insight on how the media industry’s commercial agenda is linked to the types of disseminated messages and dominant imaginaries. It compares respective codes inherent in news media and film/fictional representations of climate change on representative examples. It traces the evolution of disaster/dystopian genres that involve climate issues. It discusses the implications from such a comparat…

A classification of motivation and behavior change techniques used in self-determination theory-based interventions in health contexts

2020

While evidence suggests that interventions based on self-determination theory have efficacy in motivating adoption and maintenance of health-related behaviors, and in promoting adaptive psychological outcomes, the motivational techniques that comprise the content of these interventions have not been comprehensively identified or described. The aim of the present study was to develop a classification system of the techniques that comprise self-determination theory interventions, with satisfaction of psychological needs as an organizing principle. Candidate techniques were identified through a comprehensive review of self-determination theory interventions and nomination by experts. The study…

A critical re-examination of the academic literature on venture capital networks

2020

This paper proposes a critical re-examination of the recent trends of the literature on venture capital networks. This brief review thoroughly scrutinises three papers that are representative of the recent academic literature in this field of study. I identify their points of strength and limitations, in order to pave the way for future research. This paper shows that the study of network weak and informal ties and the role of risk management strategies are promising areas for pushing the frontiers of research on venture capital networks. Extending our knowledge on this topic is crucial to understand the best strategic decisions venture capital firms should take, as parts of an inter-organi…

Description and phylogenetic relationships of a new species of treefrog of theOsteocephalus buckleyispecies group (Anura: Hylidae)

2020

The Osteocephalus buckleyi species group is widely distributed in primary and secondary forests of the Amazon Basin and Guiana Region. Based on integrative analysis, including morphological and genetic data, we estimate the phylogenetic relationships and species boundaries among populations of the Osteocephalus buckleyi group from the Ecuadorian Amazon, focusing on the O. verruciger-O. cannatellai species complex. Our results uncovered the existence of one confirmed candidate species from Sangay National Park and one unconfirmed candidate species. Here, we describe the new species which is morphologically and ecologically distinct from other Osteocephalus species. The new species is unusual…

Modeling foreign exchange market activity around macroeconomic news: Hawkes-process approach

2015

We present a Hawkes-model approach to the foreign exchange market in which the high-frequency price dynamics is affected by a self-exciting mechanism and an exogenous component, generated by the pre-announced arrival of macroeconomic news. By focusing on time windows around the news announcement, we find that the model is able to capture the increase of trading activity after the news, both when the news has a sizable effect on volatility and when this effect is negligible, either because the news in not important or because the announcement is in line with the forecast by analysts. We extend the model by considering noncausal effects, due to the fact that the existence of the news (but not…

Activation of Stainless Steel 316L Anode for Anion Exchange Membrane Water Electrolysis

2023

The increased emphasis on renewable energy has resulted in a surge of R&D efforts into hydrogen and battery research. The intensive electrochemical environment surrounding the anodic oxygen evolution reaction (OER) has plagued both the activity and stability of the catalytic layer, substrate and porous transport layer, ultimately affecting both these industries. Herein, we report the benefits of potential cycling (PC) a 316L stainless steel felt porous transport layer (PTL) for use in anion exchange membrane water electrolysis. The PC increased surface roughness and created a CrFe5Ni2-OxHy layer through the oxidation of iron as shown by SEM, EDS, XPS, XRD and Raman spectroscopy. Post-PC tes…
