Credibility as a Key to Sustainable Advertising Success
2014
This paper addresses the operational part of sustainable marketing, especially advertising with sustainability. This form of advertising has to consider particularly the aspect of credibility since the social-ecological value of a product is often not evident for the consumer. Therefore, credibility represents an essential competitive advantage for companies who offer sustainable products. The purpose of this paper is to identify the determinants which are decisive for the credibility attribution of sustainable advertisement in order to achieve an improved comprehension of the latent construct and a more credible design of this type of advertisement. In addition, the actual influence of cre…
Information-theoretic assessment of cardiovascular variability during postural and mental stress
2016
This study was aimed at investigating the individual and combined effects of postural and mental stress on short-term cardiovascular regulation. To this end, we applied measures taken from the emerging framework of information dynamics on the beat-to-beat spontaneous variability of RR interval and systolic arterial pressure (SAP) measured from healthy subjects in the resting supine position and during the separate and simultaneous execution of experimental protocols performing head-up tilt (HUT) and mental arithmetics (MA). The information stored in RR interval variability, a measure inversely related to the complexity of the time series, increased significantly during HUT and HUT+MA compar…
An identifiable model to assess frequency-domain Granger causality in the presence of significant instantaneous interactions
2010
We present a new approach for the investigation of Granger causality in the frequency domain by means of the partial directed coherence (PDC). The approach is based on the utilization of an extended multivariate autoregressive (MVAR) model, including instantaneous effects in addition to the lagged effects traditionally studied, to fit the observed multiple time series prior to PDC computation. Model identification is performed combining standard MVAR coefficient estimation with a recent technique for instantaneous causal modeling based on independent component analysis. The approach is first validated on simulated MVAR processes showing that, in the presence of instantaneous effects, only t…
Incorporazione non riduttiva ed autoreferenzialità causale. Note per una concezione realista del sé nella teoria della coscienza di Antonio Damasio e…
2008
La critica al sostanzialismo ed al solipsismo cartesiani e l'elaborazione di una concezione naturalista ed antisostanzialista della mente hanno storicamente comportato, da David hume al funzionalismo ed alle scienze cognitive contemporanee, l'affermarsi di un atteggiamento eliminativista nei confronti del sè quale si dà ad esempio nella "narrative view" di Daniel Dennett e nella teoria della mente estesa di David Chalmers ed Andy Clark. Scopo di questo saggio è argomentare che la connessione essenziale tra mente e individualità può sopravvivere alla crisi del paradigma cartesiano mediante una rilettura del sè come processo causalmente reale e biologicamente incorporato quale si evince dalla…
A new framework for the time- and frequency-domain assessment of high-order interactions in networks of random processes
2022
While the standard network description of complex systems is based on quantifying the link between pairs of system units, higher-order interactions (HOIs) involving three or more units often play a major role in governing the collective network behavior. This work introduces a new approach to quantify pairwise and HOIs for multivariate rhythmic processes interacting across multiple time scales. We define the so-called O-information rate (OIR) as a new metric to assess HOIs for multivariate time series, and present a framework to decompose the OIR into measures quantifying Granger-causal and instantaneous influences, as well as to expand all measures in the frequency domain. The framework ex…
Clinicians' assessment of mobile monitoring: a comparative study in Japan and Spain.
2013
Background: The gradual but steady shift toward telemedicine during the past decades is a clear response to important health problems that most industrialized countries have been facing. The growing elderly population and changing dietary habits have led to an increase in people with chronic diseases and overall health care expenditures. As more consumers use their mobile device as their preferred information and communication technology (ICT) device, mobile health monitoring has been receiving increasing attention in recent years. Objective: This study examines clinicians’ perception of factors determining mobile health monitoring acceptance in Japan and Spain. The study proposes a causal …
Methods for evaluating causality in observational studies.
2019
BACKGROUND: In clinical medical research, causality is demonstrated by randomized controlled trials (RCTs). Often, however, an RCT cannot be conducted for ethical reasons, and sometimes for practical reasons as well. In such cases, knowledge can be derived from an observational study instead. In this article, we present two methods that have not been widely used in medical research to date. METHODS: The methods of assessing causal inferences in observational studies are described on the basis of publications retrieved by a selective literature search. RESULTS: Two relatively new approaches—regression-discontinuity methods and interrupted time series—can be used to demonstrate a causal relat…
Automatic Extraction of Semantic Roles in Support Verb Constructions
2021
This paper deals with paraphrastic relations in Italian. In the following sentences: (a) Max strappò delle lacrime a Sara 'Max moved Sara to tears' and (b) Max fece piangere Sara 'Max made Sara cry', the verbs differ syntactically and semantically. Strappare 'tear/rip/wring' is transitive, fare ‘have/make’ is a causative, and piangere 'cry' is intransitive. Despite this, a translation of (a) as (b) is legitimate and therefore (a) is a paraphrase of (b). In theoretical linguistics this raises an issue concerning the relationship between strappare and fare/piangere in Italian, and that in English between move and make. In computational linguistics, can such paraphrases be obtained automatical…
Consumer behavior in a religious event experience: an empirical assessment of value dimensionality among volunteers
2009
PurposeThe purpose of this paper is to present volunteering in tourism events as a sort of spontaneous community participation that has far‐reaching consequences for destination management. It chooses the concept of value to explore volunteering experience in an international religious mega‐event, using Holbrook's value typology (efficiency, social value, play, spirituality).Design/methodology/approachThe authors undertake this objective by means of testing psychometric properties of the four value scales, as well as providing a causal model of relationships among value dimensions and overall perceived value, satisfaction and loyalty or commitment to volunteering in a special event tested w…
Mind, brain, and downward causation
2011
Este trabajo tiene tres partes. En la primera, exponemos algunas nociones básicas, como las de causalidad mental e intencional, así como la de causalidad misma; procedemos a continuación a formular algunas tesis, inspiradas en las ciencias naturales, y a mostrar cómo parecen entrar en conflicto con la aceptación de la causalidad intencional. Este conflicto es el núcleo del problema de la causalidad mental. En la segunda parte, presentamos y discutimos brevemente algunas propuestas para abordar este problema, y tratamos de sacar a la luz sus dificultades. Finalmente, en la tercera parte, planteamos tentativamente algunas sugerencias sobre el modo en que el problema de la causalidad intencion…
