No full textThe internet has become an irreplaceable instrument for people of the 21st century. In light of the Activity Theory, it can be seen as the technological part of the functional organs that augment a human’s opportunities to carry out activities and achieve specific objectives. While acting as a tool, the in-ternet can lead to the risk of an ‘inverse instrumentality’ process in which people lose their sense of self-directedness and experience a passive and un-controlled approach to technology. Past research has stressed the importance of cognitive involvement with technology for a healthy use of the internet. Nevertheless, it is still not clear whether cognitive involvement does protect against the misuse of new media, or whether it is an antecedent of it. In this study two dimensions of the Cognitive Absorption Scale (Focused Immersion and Temporal Dissociation) were used as mediators between antecedents of internet misbehaviors (Self-Control, Mindfulness and Self-Esteem) and Prob-lematic Internet Use. Only Temporal Dissociation was found to act as a me-diator. Furthermore, the scores on the Focused Immersion scale were posi-tively predicted by levels of Self-esteem and Self-control. This suggests that certain ways of experiencing cognitive involvement are more risky than oth-ers. Implications for professionals and future research are discussed
The Cassandra Experience: A Mixed Methods Study on the Intragroup Cognitive Dissonance of Italian Expatriates During the First Wave of COVID-19
No full textIn March 2020, Italy was the first European country to be hit severely by the first wave of coronavirus disease 2019 (COVID-19) and to put in place moderate-high containment measures. 594 Italian expatriates participated in a cross-sectional mixed-methods survey focusing on the period that goes from the beginning of March 2020 to the beginning of April 2020. The survey aimed to describe the experiences of participants when it comes to conflicting beliefs and behavior with the Italian or host country communities in relation to COVID-19, using the Intragroup Cognitive Dissonance (ICD) framework. We explored: (1) COVID-19 risk perception (assessed for themselves, the Italian community, and the host country community); (2) COVID-19 risk meta-perception (participants’ perception of the Italian and host country communities’ risk perception); (3) intensity of emotions (assessed for themselves); (4) national group identification (assessed for themselves in relation to the Italian and host country communities) before and after the first wave of COVID-19 in Italy. An inductive thematic analysis of three open-ended questions allowed an in-depth understanding of the experiences of Italian expatriates. Results describe the ICD of participants with the Italian or host country communities, expressed as a difference between COVID-19 risk-perception and risk meta-perception. ICD predicts that when a dissonance of beliefs and behavior is experienced within an individual’s group, a shift in identification with another more consonant group will happen, if identity enhancing strategies with the dissonant group are unsuccessful. Our findings showed that when the ICD was experienced with the host country community, this was solved through a disidentification strategy and mediated by negative emotions. Identity enhancing strategies with the host country community were unsuccessfully enacted as described by the qualitative answers of participants referring to episodes of racism, ridicule, and to a Cassandra experience: predicting a catastrophic future without being believed. Unexpectedly, participants experiencing the ICD with the Italian community did not enact a disidentification strategy. An increase in virtual contacts, enhanced sense of belonging, a stronger identification baseline, and different features of the two ICDs can be responsible for these results. This study sheds light on the relevance of ICD in natural settings and on international communities, during global crises
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
[On the genesis of the first heart sound: phono-echocardiographic study in patients with A-V block (author's transl)].
No full textA phono-echocardiographic study of acustic and morphologic events was performed in three patients with atrioventricular block in order to assess the role of the mitral valve in the changes of the amplitude of the first heart and, more generally, in the genesis of the first heart sound. Simultaneous recording of the electrocardiogram, the apical phonocardiogram and the mitral echocardiogram showed: 1) the coincidence between the C point of the echocardiogram and the onset of the earlier high frequency vibrations of the first heart sound (M1); 2) a close correlation between the intensity of the first heart sound and the position of the mitral valve at the onset of ventricular systole (P less than 0.001); 3) longer duration of the first heart sound in those beats when there was superimposition of P wave in QRS. The authors illustrate the recent reports about the genesis of the first heart sound and emphasize the main role of the mitral valve suggesting that the position of the mitral leaflets at the onset of ventricular systole influences the mechanism of acceleration and deceleration of blood and vibrations of the "cardiohemic system"
