Perceptions, attitudes and ethical valuations: The ambivalence of the public image of biotechnology in Spain
2000
This paper analyzes the study of the public perception of biotechnology, comparing different studies made on the European and the Spanish national levels. It aims at testing the applicability of these kinds of studies, and describes some of their limits. The analysis shows clear ambivalence in the public response to distinct applications of this technology, pointing out the crucial differences between general moral valuation and attitude towards specific products. Taking into account this difference appears fundamental for the design of future perception studies able to more accurately reflect public understanding.
Air pollution in European countries and life expectancy—modelling with the use of neural network
2019
Abstract The present paper discusses a novel methodology based on neural network to determine air pollutants’ correlation with life expectancy in European countries. The models were developed using historical data from the period 1992–2016, for a set of 20 European countries. The subject of the analysis included the input variables of the following air pollutants: sulphur oxides, nitrogen oxides, carbon monoxide, particulate matters, polycyclic aromatic hydrocarbons and non-methane volatile organic compounds. Our main findings indicate that all the variables significantly affect life expectancy. Sensitivity of constructed neural networks to pollutants proved to be particularly important in …
Gaze position reveals impaired attentional shift during visual word recognition in dysfluent readers
2014
Effects reflecting serial within-word processing are frequently found in pseudo- and non-word recognition tasks not only among fluent, but especially among dyslexic readers. However, the time course and locus of these serial within-word processing effects in the cognitive hierarchy (i.e., orthographic, phonological, lexical) have remained elusive. We studied whether a subject’s eye movements during a lexical decision task would provide information about the temporal dynamics of serial within-word processing. We assumed that if there is serial within-word processing proceeding from left to right, items with informative beginnings would attract the gaze position and (micro-)saccadic eye movem…
Nurses' perception of the oncology patient's death: a qualitative study
2021
Death is one of the basic theme with which nurses are faced, and for which it is hard for them to prepare deeply and sincerely. The difficulties in handling the emotional burden can cause them to develop negative feelings towards life and clinical practice, so that it affects their caregiving capacity and the quality of care provided.To explore nurses' perceptions facing the death of a hospitalized oncology patient.Qualitative phenomenological study. The sample of nurses was recruited at IRCCS (Scientific Institute for Research and Healthcare) in Rome, a hospice in Latina and a hospice in Rieti. The data were collected by means of focus groups. The semi-structured interviews featuring three…
Taking part in Nordic collaboration : nursing students' experiences and perceptions from a learning perspective: a qualitative study
2015
BACKGROUND: Nordic networking of different kinds has a long tradition aiming to increase collaboration and understanding between citizens in different countries. Cultural competence in relation to health care and nursing is important for clinical nurses and is a central issue in nurse education. OBJECTIVE: To gain an understanding of what nurse students experienced and learned during an intensive course in diabetes together with students and nurse educators from Denmark, Finland, Iceland, Norway, Sweden and the Faroe Islands. METHODS: In 2012, an intensive course within the Nordic network, Nordkvist, was conducted in Faroe Islands with the theme "Nursing - to live a good life with diabetes"…
Competitive Cycling and Doping: Proposing a Functional Analysis Based on the Color Yellow.
2015
The authors demonstrate in three experiments (N = 241) that yellow impacts on social perceptions when associated with competitive cycling. In Experiment 1, the image of a syringe evocated competitive cycling and doping more strongly when presented on yellow as compared with gray. In Experiment 2, a performance improvement scenario yielded more discredit of a depicted racer and higher suspicions of doping when ending on a yellow frame, as opposed to a gray one. In Experiment 3, the image of a racer wearing a yellow jersey (instead of a gray or a white one) yielded the lowest scores on measures of suitability as a role model and attractiveness of sport participation. Moreover, no significant …
Judging body weight from faces: the height-weight illusion.
2012
Being able to exploit features of the human face to predict health and fitness can serve as an evolutionary advantage. Surface features such as facial symmetry, averageness, and skin colour are known to influence attractiveness. We sought to determine whether observers are able to extract more complex features, namely body weight. If possible, it could be used as a predictor for health and fitness. For instance, facial adiposity could be taken to indicate a cardiovascular challenge or proneness to infections. Observers seem to be able to glean body weight information from frontal views of a face. Is weight estimation robust across different viewing angles? We showed that participants stron…
How Much Money Do You Need to Feel Taller? Impact of Money on Perception of Body Height
2021
Body height is considered to be one of the most important reproductive signals. However, there are only a few publications on what influences the sense of whether we assess ourselves as tall or short. In the present contribution, the psychological impact of money on the evaluation of a person’s own height was tested. We performed two experimental studies in which the respondents had contact with different amounts of money and were asked to evaluate their body height with the use of a laser pointer. The first experiment (N = 61) showed that contact with money significantly increased subjective height evaluation, and the effect was independent of participants’ real body height. The second exp…
Effect of Camera Angle on Perception of Trust and Attractiveness
2017
Film theories have long proposed that the vertical camera angle influences how the scene and the character in it are interpreted. An elevated camera (high-angle shot) should diminish the qualities of the actor, whereas a lowered camera (low-angle shot) should elevate the actor in perspective as well as in the viewer’s opinion. We were interested in how this holds up for the impression of trustworthiness and attractiveness that the spectator receives of the actor. We filmed 12 actors in a scenario inspired by a TV show called Split or Steal, which features a one-time version of the prisoner’s dilemma. Subjects had to rate trustworthiness and attractiveness of the actors, and also judge if t…
Genre-dependent effects of 3D film on presence, motion sickness, and protagonist perception
2016
Do the increasingly popular 3D movies change how we perceive the content of the movie? We presented short (3.21 min) film sequences to observers equipped with shutter glasses. Three genres (horror, action, and documentary) were crossed with three between-subjects viewing conditions (director’s 3D, artificial 3D, and 2D). Observers had to rate how the film impressed them in terms of arousal, motion sickness, presence, and immersion. They also judged the personality, attractiveness, and intelligence of the protagonist in all viewing conditions. Not surprisingly, horror films produced more arousal and presence than action films. Documentaries scored lowest on presence. Action movies produced t…
