How many cyberbullying(s)? A non-unitary perspective for offensive online behaviours.

Research has usually considered cyberbullying as a unitary phenomenon. Thus, it has been neglected to explore whether the specific online aggressive behaviours relate differentially to demographic features of the perpetrators of online aggressive actions, their personality characteristics, or to the ways in which they interact with the Internet. To bridge this gap, a study was conducted through a questionnaire administered online to 1228 Italian high-school students (Female: 61.1%; 14-15 yo: 48.%; 16-17 yo: 29.1%; 18-20 yo: 20.4%, 21-25 yo: 1.6%; Northern Italy: 4.1%; Central Italy: 59.2%; Southern Italy: 36.4%). The questionnaire, in addition to items about the use of social media, mechanisms of Moral Disengagement and personality characteristics of the participants in the study, also included a scale for the measurement of cyberbullying through the reference to six aggressive behaviours. The results indicate that cyberbullying can be considered as a non-unitary phenomenon in which the different aggressive behaviours can be related to different individual characteristics such as gender, personality traits and the different ways of interacting with social media. Moreover, the existence of two components of cyberbullying has been highlighted, one related to virtual offensive actions directly aimed at a victim, the other to indirect actions, more likely conducted involving bystanders. These findings open important perspectives for understanding, preventing, and mitigating cyberbullying among adolescents.

University Teachers During the First Lockdown Due to SARS-CoV-2 in Italy: Stress, Issues and Perceptions of Misconduct.

With the spread of the pandemic and the introduction of measures aimed at its containment, it is necessary to understand in specific national contexts how home quarantine has affected the psychophysical well-being of academics, and their ability to maintain integrity. To this end we constructed an online questionnaire to investigate the levels of stress, well-being, and work-life balance in relationship with living and working conditions. Moreover, the questionnaire was designed to obtain information about the perceived occurrence, increase or decrease of misconduct in research (e.g., research misconduct by colleagues) and professional relationships (e.g., misbehaviors between colleagues, from students and toward students). The questionnaire was administered online by contacting faculty at three universities in Tuscany, Italy, asking them to relate their experience during the first lockdown (March-May 2020). Faculty members were invited to complete the questionnaire by their institutional e-mail account. The final sample consisted of 581 respondents. The results showed that inadequacies of the equipment, and particularly poor internet connection, were significantly correlated with main issues reported, such as relationships with students and research activities. Female teachers primarily suffered from stressful conditions, lacked well-being, and experienced work-life imbalance. Stress levels were related to perceptions of the frequency of misconduct and of an increase in their frequency during the period of home quarantine. Female professors, when compared to their male counterparts, perceived misconduct from students as increased and more frequent in the period of quarantine. Results point to a gender issue that is likely to arise from conditions of domestic activities imbalance and that increases stress and misconduct perception.

Mid-air haptics for shape recognition of virtual objects.

This paper presents an experiment in which participants had to discriminate three mid-air haptic shapes (circle, square, point) by reporting whether the haptic stimulus (e.g. circle on the palm of the hand) was compatible with an image (e.g. a circle) or a word (e.g. 'circle') displayed on a screen. Results indicate that only the 'point' stimulus was appreciably recognised and discriminated in terms of accuracy and time needed for the identification. Accuracy increased with repetition, and response time decreased, suggesting a learning effect. The comparison between visual and textual labels shows that for the haptic point stimulus there is no significant difference but a tendency to have greater accuracy with images than with texts, while the opposite result is found for the circle stimulus. This outcome suggests the need for new experiments focussed of the effect of visual/textual labels to make the recognition/discrimination tasks of haptic stimuli easier. Practitioner Summary: Three haptic shapes were presented with images or texts, matching or not the stimuli. The point was easy to recognise, while the circle and the square were difficult to discriminate against each other. Visual/textual labels bring contradictory results for different shapes.

Perception of Faces and Elaboration of Gender and Victim/Aggressor Stereotypes: The Influence of Internet Use and of the Perceiver's Personality.

The use of social media, particularly among youngsters, is characterized by simple and fast image exploration, mostly of people, particularly faces. The study presented here was conducted in order to investigate stereotypical judgments about men and women concerning past events of aggression-perpetrated or suffered-expressed on the basis of their faces, and gender-related differences in the judgments. To this aim, 185 participants answered a structured questionnaire online. The questionnaire contained 30 photos of young people's faces, 15 men and 15 women (Ma et al., 2015), selected on the basis of the neutrality of their expression, and participants were asked to rate each face with respect to masculinity/femininity, strength/weakness, and having a past of aggression, as a victim or as a perpetrator. Information about the empathic abilities and personality traits of participants were also collected. The results indicate that the stereotypes-both of gender and those of victims and perpetrators-emerge as a consequence of the visual exploration of faces that present no facial emotion. Some characteristics of the personality of the observers, such as neuroticism, extraversion, openness, conscientiousness, and affective empathy, have a role in facilitating or hindering stereotype processing, in different ways for male and female faces by male and female observers. In particular, both genders attribute their positive stereotypical attributes to same-gender faces: men see male faces as stronger, masculine, and more aggressive than women do, and women see female faces as more feminine, less weak, and less as victims than men do. Intensive use of social media emerges as a factor that could facilitate the expression of some stereotypes of violent experiences and considering female subjects as more aggressive. Findings in this study can contribute to research on aggressive behavior on the Internet and improve our understanding of the multiple factors involved in the elaboration of gender stereotypes relative to violent or victim behavior.

Perceptions of Work-Related Stress and Ethical Misconduct Amongst Non-tenured Researchers in Italy.

The relationship between stress and unethical behaviour amongst non-tenured research staff in academia is a relatively unexplored phenomenon. The research reported herein was therefore carried out with the aim of exploring the relationship(s) between stress, the socio-organisational factors which contribute to it, job satisfaction, perceptions of job instability, and the occurrence of unethical behaviour in research. 793 Italian researchers participated in the research-all of whom were working on fixed-term contracts-after being individually requested to complete an online questionnaire. The data indicate that unethical behaviours occur with alarming frequency. The stress level reported is quite high, as is the level of perceived job insecurity, both of which impact upon levels of job satisfaction. Perceived stress levels also seem to play a role in the commission of unethical behaviours, but this relationship is irrelevant when one considers the role of social and organisational factors that are known to induce it. Indeed, it seems that there are various socio-organisational determinants of stress that have an obvious direct negative influence on the commission of unethical behaviours more than the stress level per se. This research paints a worrying picture in relation to the psycho-physical state of non-tenured researchers as a result of the working conditions in which they find themselves in Italian universities.

Perceptions and Use of Computed Tomography in a Hospital Emergency Department: Technicians' Perspectives.

OBJECTIVE: This study traces the evolution of perceptions and use of computed tomography (CT) by radiology technicians in the emergency department (ED) of a hospital in Italy across a 7-year period. BACKGROUND: The sociotechnical context of the CT room of an ED has been neglected by scientific research-potentially impacting safety. METHOD: Two studies were performed, one in 2011 and one in 2018. Six CT technicians were involved in each. Structured interviews were performed to gather information on perceptions related to the evolution of the use of CT according to nine different factors-e.g. the level of complexity, and mental workload. Observations were performed on duration of exams, the flow of people, conversations, and any critical issues. RESULTS: The CT technology is appreciated, used effectively and with confidence by CT technicians. From 2011-2018, the execution times of the exams have decreased but not the proportion of time dedicated to the patient. Expectations for future improvements are limited by issues concerning the design of both the user interface and the social context of the ED workplace. CONCLUSIONS: The safety and efficiency of the system as a whole are greatly dependent on the competence of the CT technicians. CT manufacturers rely on this competence to help compensate for the deficiencies created by suboptimal user interfaces and the lack of fit of the technology with the social context of the workplace. APPLICATION: Training programs aimed at improving the management of relationships and communications between staff could improve performance and efficiency. CT manufacturers should try to better understand the cognitive and operational context of the workplaces where CT technicians work-and to design better diagnostic technology which accounts for these operational realities.

The possible role of empathy and emotions in virtual negotiation.

The goal of the present study is to explore the role of empathic and emotional skills in virtual negotiation, and to try to verify their possible role in different contexts: monetary/non-monetary, in circumstances in which a counterparty is familiar or unknown, and with respect to polite or rude responses from the negotiating counterparty. To this end, 320 participants aged between 19 to 25 years old were involved in a simulated virtual negotiation. Participants were required to fill in a Basic Empathy Scale (BES) questionnaire, they were also asked to report the prevalent emotion they had felt during the interaction, and if they thought they were interacting with a real person. The results of this research confirm the tendency of participants to minimise losses. Although the capacity for empathy does not seem to have a role, the behaviour of participants appears more cooperative when they have to deal with a familiar negotiation counterparty. Emotions appear to play a positive role when negotiating with, what is perceived to be, a real person. Practitioner summary: We conducted this study as part of a Master's Degree programme which was specifically focussed on human-computer interaction. Results show that negotiation was affected by emotions experienced during the experiment, and by the perception of the negotiating counterparty as a familiar person more so than by empathy. Abbreviations: AE: affective empathy; AMIS: assessment model of internet systems; ANOVA: ANalysis Of VAriance; BES: base empathy scale; CE: cognitive empathy; CMC: computer mediated communication; ENS: e-negotiation systems; FTF: face-to-face communication; NSA: negotiation support agents; PC: personal computer.

Offensive acts and helping behavior on the internet: An analysis of the relationships between moral disengagement, empathy and use of social media in a sample of Italian students.

BACKGROUND: The phenomenon of cyberbullying is on the rise among adolescents and in schools. OBJECTIVE: To evaluate the relationship between personality characteristics such as empathy, the tendency to implement cognitive mechanisms aimed at moral disengagement, and the use of social media. PARTICIPANTS: Italian students from first to fifth year in high school classes (n = 264). METHODS: A questionnaire was used to gather information on the sociodemographic characteristics of the participants, their use of social media, their level of empathy (Basic Empathy Scale, BES), and mechanisms of moral disengagement (Moral Disengagement Scale MDS). Two questions were included to determine whether each participant had ever been a victim of or witness to cyberbullying. RESULTS: Results suggest that offensive behaviors are related to mechanisms of moral disengagement and to interaction using forms of communication that allow anonymity. In addition, offensive behavior appears to be related to forms of Internet addiction, while prosocial behavior is linked with cognitive empathy. CONCLUSION: In order to promote the establishment of prosocial behavior, it would seem necessary for the various players involved - schools, parents, social network developers - to make an effort to implement educational environments and virtual social networks based on a hypothesis of "design for reflection", educating young people about the need to take the time to understand their feelings and relationships expressed via social media.

Illusory Streaks from Corners and Their Perceptual Integration.

Perceptual grouping appears both as organized forms of real figural units and as illusory or "phantom" figures. The phenomenon is visible in the Hermann grid and in configurations which generate color spreading, e.g., "neon effects." These configurations, generally regular repetitive patterns, appear to be crossed by illusory bands filled with a brighter shade or a colored tinge connecting the various loci of illusory effects. In this work, we explore a particular new illusion showing a grouping effect. It manifests as illusory streaks irradiating from the vertexes of angular contours and connecting pairs of figures nearby. It is only clearly visible when more than one figure is shown, and takes the shape of a net crossing their corners. Although the grouping effect is vivid, the local source of the illusion is completely hidden. Theories explaining this effect as due to the irradiation of illusory streaks (mainly that of Grossberg and Mingolla, 1985a,b) do not fully explain the figural patterns presented here. Illusory effects have already been documented at the angles of various figures, causing them to alter in amplitude and brightness; however, the figure illustrated here appears to have different features and location. Phenomenological observations and an experiment were conducted to assess the role played by geometric and photometric parameters in this illusion. Results showed that sharp angles, in low contrast with the surround, are the main source of the illusion which, however, only becomes visible when at least two figures are close together. These findings are discussed with respect to theories of contour processing and perceptual grouping, and in relation to other illusions.

A mind in a disk: the attribution of mental states to technological systems.

This paper reports a study about the role of different variables in the process of attributing mental states to technological systems, variables such as the number of figural elements displayed in the system and the personality traits of the subjects interacting with the systems. In an experiment, participants were interacting with a computer on whose screen several disks of various sizes and colours were blinking at different rates. Each time a disk reappeared on the screen its position was randomly varied. As in a videogame, participants had to click on the disks to increase their score. The results showed that, even in the case of such a simple system, subjects believed that the figural elements they were interacting with had some form of mental states, although their confidence in these beliefs varied in the different experimental conditions. The confidence level of the attributions, in fact, was not the same for all the different mental states considered, and it varied also both with the number of elements being displayed as well as with some personality traits of the subjects.

Features of the selectivity for contrast polarity in contour integration revealed by a novel tilt illusion.

We studied a novel illusion of tilt inside checkerboards due to the role of contrast polarity in contour integration. The preference for binding of oriented contours having same contrast polarity, over binding of opposite polarity ones (CP rule), has been used to explain several visual illusions. In three experiments we investigated how the binding effect is influenced by luminance contrast value, relatability of contour elements, and distance among them. Experiment 1 showed that the effect was indeed present only when the CP rule was satisfied, and found it to be stronger when the luminance contrast values of the elements are more similar. In experiment 2 the illusion was reported only with relatable edges, and its strength was modulated by the degree of relatability. The CP-rule effectiveness, thus, seems to depend on good continuation. The intensity of contrast polarity signals propagating from an oriented contour might be the less intense, the more its direction deviates from linearity. In experiment 3 we estimated the distance threshold and found it to be smaller than the one found for other illusions, arising with collinear fragments. This seems to show that the reach of the contrast polarity signal inside the association field of a contour unit is shorter along non-collinear orientations than along collinear ones.

Draughtsmen at work.

To obtain the representation of a contour, the visual system integrates fragments of a pattern. One of the 'binding rules' governing this process requires that a path of conjunction in which contrast polarity is preserved be followed. Here we show that this rule has a corollary: where two alternative paths compete to emerge in opposite directions, the one with greater contrast luminance is likely to prevail.

Are hospitals becoming high reliability organizations?

High Reliability Organizations (HROs) are complex systems in which many accidents and adverse events that could occur within those systems or at the interfaces with other systems are actually avoided or prevented. Many organizations in high-risk industries have successfully implemented HRO approaches. In recent years, initiatives have been undertaken aimed at transforming hospitals into HROs. Actually, despite some improvements, these initiatives have not shown the expected results. In this paper, we discuss the possible reasons for such outcomes. We will show that, when compared with traditional HROs, hospitals are undoubtedly high-risk organizations, but have specificities and experience systemic socio-organizational barriers that make them difficult to transform into HROs.

Boundary completion, contrast polarity, and the perception of illusory tilt.

What we perceive as a unitary object can be the result of integrative processes that generate a whole from parts. Although this issue of visual perception has been widely explored, recent experimental findings demonstrate that our knowledge is still incomplete. In particular, the question whether contour binding is affected by the sign of contrast (contrast polarity) across edges requires more in-depth examination. Here we show the effects of edge bindings that originate from the merging of laterally displaced edges with the same contrast polarity. We have studied a particular context in which such effects may emerge: a checkerboard with a series of alternated dark and light shapes superimposed on the corners of the squares. The phenomenal observations and experimental findings support the theories according to which boundary completions are originated by phenomena of edge propagation within a 'field of completion' (eg Shipley and Kellman, 2003 Perception 32 985-999) adjacent to an edge ending. Our findings conform to the Shipley and Kellman theory that boundary completion results from the interaction of edges as well as from edges and shapes lacking in oriented contours, the latter serving as 'receiving units', anchoring the paths of activations generated by oriented edges. We propose to integrate this theory with the hypothesis that interactions sensitive to the contrast sign generate conjunction paths of edges that alter their perceived orientation. Based on this perspective we propose an alternative account for the Café Wall illusion that can be extended to other phenomena of orientation misperception and to a Café Wall inversion effect that has not been observed previously.
