Moral disengagement and generalized social trust as mediators and moderators of rule-respecting behaviors during the COVID-19 outbreak

In this study, we tested a theoretical model with moral disengagement, a mediator,and generalized social trust (GST), a mediator and a moderator of the relationshipbetween personality traits and rule-respecting behaviors (i.e., social distancing andstay-at-home), during the coronavirus disease 2019 (COVID-19) outbreak in Italy. Thedata were collected on 1520 participants (61% males). General results are threefold: (1) moral disengagement mediated the relationship between emotional stability, narcissism,psychopathy, and social distancing; (2) among components of GST, trust in Governmentmediated the relationship between psychopathy and social distancing; trust in knownothers mediated the relationship between emotional stability, agreeableness, andMachiavellianism with total number of exits; trust in unknown others mediated therelationship of emotional stability, agreeableness, conscientiousness, and psychopathywith average daily number of exits; (3) GST moderated the indirect effect of personalitytraits on rule-respecting behaviors through moral disengagement. The theoretical andpractical importance of these results is discussed

Breaking the rules of time-domain diffuse optics: working with 1 cm2 SiPM and well-beyond the single-photon statistics

Time domain diffuse optics (TD-DO) relies on the injection of ps laser pulses and on the collection of the arrival times of scattered photons. To reach the ultimate limits of the technique (allowing to investigate even structures at depth >5 cm), a large area detector is needed. To this extent, we realized and present a new silicon photomultiplier featuring a 1 cm2 area. To the best of our knowledge, it represents the largest detector ever proposed for TD-DO and shows a light harvesting capability which is more than 1 decade larger than the state-of-the-art technology system. To assess its suitability for TDDO measurements, we tested the detector with several procedures from shared protocols (BIP, nEUROPt and MEDPHOT). However, the light harvesting capability of a detector with large area can be proficiently exploited only if coupled to timing electronics working in sustained count-rate CR (i.e., well above the single photon statistics). For this reason, we study the possibility to work in a regime where (even more than) one photon per laser pulse is detected (i.e., more than 100% laser repetition rate) exploiting in-silico technology. The results show that the possibility to use sustained count-rate represents a dramatic improvement in the number of photons detected with respect to current approaches (where count-rate of 1-5% of the laser repetition rate are used) without significant losses in the measurement accuracy. This represents a new horizon for TD-DO measurements, opening the way to new applications (e.g., optical investigation of the lung or monitoring of fast dynamics never studied before)

When age matters: The role of teacher aging on job identity and organizational citizenship behaviours

The increasing aging of the work population, on one hand, and the increasing rates of work instability and unemployment among young people, on the other hand, make the maintaining of an engaged and highly performing workforce a great challenge for both researchers and practitioners. A crucial role may be played by job identity. The present paper aims at examining age differences on job identity and how patterns of personal and social identities in specific age group are differentially related to the organizational citizenship behaviours. Participants were 515 teachers (85.4% women) divided into settling-in adults (aged 24-39 years), prime working years (aged 40-54 years), and approaching retirement employees (aged 55-64 years). Analyses of variance revealed that identity commitment and organizational identification were higher in older teachers, while group identification was higher in younger employees. Regression analyses were used to test whether various facets of job identity had a different effect on organizational citizenship behaviours in the various age groups. Implications and future research agenda are discussed

The steel industry: a mathematical model under environmental regulations

In this work, a spatial equilibrium problem is formulated for analyzing the impact of the application of the EU-ETS on the steel industry that has historically seen Europe as one of its major producers. The developed model allows us to simultaneously represent the interactions of several market players, to endogenously determine output and steel prices and to analyze the investment in the Carbon Capture and Storage (CCS) technology. In addition, the proposed model supports the evaluation of the CO2 emission costs on the basis of Directive 2009/29/EC, the “20-20-20” targets, and the Energy Roadmap 2050. In this light, two main processes for steelmaking have to be considered: integrated mills (BOF) and Electric Arc Furnace (EAF) in minimills

Personal and Social Facets of Job Identity: A Person-Centered Approach

Purpose: The purpose of this study was to examine ego-identity (Erikson, Psychol Issues 1:1-171, 1959; Identity, youth and crisis, Norton, New York, 1968; Marcia, J Pers Soc Psychol 3:551-558, 1966) and social identity (Tajfel and Turner, In: Austin WG, Worchel S (Eds.) The social psychology of intergroup relations. Brooks/Cole, Monterey, pp 33-47 1979; Turner et al., Rediscovering the social group: A self-categorization theory. Blackwell, Oxford, 1987) theories within the organizational literature. We adopted a person-centered approach to analyze whether employees classified in various identity statuses and identification profiles exhibited differences in job outcomes (i.e., burnout, job satisfaction, and organizational citizenship behaviors). We also analyzed interconnections among identity statuses and identification profiles. Design/methodology/approach: Participants were 515 employees (85.4 % women) between 24 and 64 years old. They completed self-reported questionnaires assessing personal identity, social identity, and job outcomes. Findings: Cluster analysis indicated that participants could be classified into four identity statuses (i.e., achievement, early closure, moratorium, and searching moratorium) and into four identification profiles (i.e., orthogonal combinations of high vs. low organizational and group identification, respectively). Employees classified in the various identity statuses and identification profiles reported meaningful differences on job outcomes. Further, findings highlighted significant associations between identity statuses and identification profiles, giving rise to various identity configurations associated with job outcomes. Implications: This study highlights the importance of integrating different facets of job identity. These findings have relevant implications in terms of suggesting which dimensions of identity should be promoted in order to reduce workers' burnout, and enhance their satisfaction and organizational citizenship behaviors. Originality/value: This study provides evidence for integrating ego-identity and social identity theories. In doing so, it bridges developmental psychology literature on personal identity with social and organizational psychology literature on social identity, setting the basis for a comprehensive line of research

Effects and correctability of pile‑up distortion using established figures of merit in time‑domain diffuse optics at extreme photon rates

Time-domain diffuse optics (TD-DO) allows one to probe diffusive media with recognized advantages over other working domains but suffers from a poor signal-to-noise ratio (SNR) resulting from the need to build-up the histogram of single-photon arrival times with maximum count rates (CR) of few percent of the laser pulse rate to avoid the so-called “pile-up” distortion. Here we explore the feasibility of TD-DO under severe pile-up conditions with a systematic in-silico/experimental study evaluating the effects and correctability of the distortion by means of shared figures of merit. In-silico, we demonstrate that pile-up correction allows one the retrieval of homogeneous optical properties with average error < 1% up to a CR > 99%, while the optimal CR needed to detect localized perturbation was found to be 83%. Experiments reported here confirm these findings despite exhibiting higher accuracy errors in the retrieval of homogeneous optical properties and higher noise in the detection of localized absorption perturbations, but in line with the state-of-the-art systems. This work validates a new working regime for TD-DO, demonstrating an increase of the SNR at constant acquisition time, but also potentially leading in the future to previously unrealizable measurements of dynamic phenomena or in spatial scanning applications
