The relationship between maladaptive personality functioning and problematic technology use in adolescence: A cluster analysis approach

In the last two decades, scientific research has explored the problematic use of internet, videogames and mobile phones. However, there is still little consistent knowledge regarding the co-occurrence of problematic technology use and the role of maladaptive personality characteristics in adolescence. The present study aimed to investigate adolescents' styles of technology use with a cluster analysis approach focusing on personality functioning. The sample comprised 408 Italian adolescents (46.3% males) aged 11 to 18 years (M _age = 13.80; SD = 2.08). Data were collected using the Internet Addiction Test, the Videogame Dependency Scale, the Test of Mobile-Phone Dependence Brief Form and the Personality Inventory for DSM5 Brief Form. Results provided a four-cluster solution based on the co-occurrence of problematic technology use. The four clusters were labeled as follows: cluster 1: “Above average internet and mobile-phone use”; cluster 2: “Below average technology use”; cluster 3: “Above average videogame use”; and cluster 4: “Problematic technology use.” Analyses on demographic variables (e.g., gender and age) demonstrated significant differences between the four groups. Adolescents with high levels of problematic technology use reported greater overall personality dysfunction than the other three groups. This finding supported our hypothesis on maladaptive personality functioning in adolescents at risk for addiction. Finally, the Antagonism domain played a specific role in differentiating the severity of adolescents' involvement in technology use. Further studies are needed to confirm our findings and to plan preventive interventions as well as therapeutic treatments.     

Hybrid Indexicals and Ellipsis

In this essay, I explain how certain suggestions put forth by Frege, Wittgenstein, and Schlick regarding the interpretation of indexical expressions may be incorporated within a systematic semantic account. I argue that the ‘hybrid’ approach they propose is preferable to more conventional systems, in particular when it comes to the interpretation of cases of cross-contextual ellipsis. I also explain how the hybrid view entails certain important and independently motivated distinctions among contextually dependent expressions, for instance between ‘here’ and ‘local’.     

Burnout and self-perceptions of physical fitness in a sample of Italian physical education teachers

This study examined the relations of physical education teachers' burnout with some individual variables, including teachers' self-perceived physical fitness and the perceived influence of personal fitness on teaching. Participants were 219 Italian physical education teachers in secondary school. Demographic and professional information, ratings of self-perception of physical condition, and the Italian version of the Maslach Burnout Inventory were recorded. Compared to the data of a normative sample, average scores on the three dimensions of the Maslach Burnout Inventory (Emotional Exhaustion, Depersonalisation, and Reduced Personal Accomplishment) were found. There were statistically significant associations among Reduced Personal Accomplishment, the self-perception of physical fitness, and the perception of the influence of personal fitness on teaching. Women reported scores on Emotional Exhaustion and Reduced Personal Accomplishment indicative of greater severity than men. No significant differences appeared to be related to the years of teaching. Recommendations for further studies are discussed.     

Web usability evaluation with screen reader users: implementation of the partial concurrent thinking aloud technique

A verbal protocol technique, adopted for a web usability evaluation, requires that the users are able to perform a double task: surfing and talking. Nevertheless, when blind users surf by using a screen reader and talk about the way they interact with the computer, the evaluation is influenced by a structural interference: users are forced to think aloud and listen to the screen reader at the same time. The aim of this study is to build up a verbal protocol technique for samples of visual impaired users in order to overcome the limits of concurrent and retrospective protocols. The technique we improved, called partial concurrent thinking aloud (PCTA), integrates a modified set of concurrent verbalization and retrospective analysis. One group of 6 blind users and another group of 6 sighted users evaluated the usability of a website using PCTA. By estimating the number of necessary users by the means of an asymptotic test, it was found out that the two groups had an equivalent ability of identifying usability problems, both over 80%. The result suggests that PCTA, while respecting the properties of classic verbal protocols, also allows to overcome the structural interference and the limits of concurrent and retrospective protocols when used with screen reader users. In this way, PCTA reduces the efficiency difference of usability evaluation between blind and sighted users.
