ABSTRACT
This study examined the associations among availability expectations, work-related smartphone use during non-work hours, and psychological detachment from work. In addition, we studied the role of segmentation preference in these associations. A total of 223 employees completed an online questionnaire. We hypothesized that smartphone use during non-work hours partially mediates the negative relationship between availability expectations and psychological detachment. We expected that segmentation preference would moderate this mediation effect. Finally, we examined the direction of this abovementioned moderating effect. The results supported our hypotheses and revealed a weak mediating effect of smartphone use during non-work hours on the relationship between availability expectations and psychological detachment. Moreover, the mediating effect is more substantial for people with low segmentation preferences. Furthermore, the practical implications of these findings are discussed.(AU)
El estudio analiza la asociación entre expectativas de disponibilidad, utilización del móvil con fines laborales fuera del trabajo y la desconexión psicológica del trabajo. Se estudia además el papel que juega en estas asociaciones la preferencia por la segmentación. Una muestra de 223 empleados cumplimentó un cuestionario por internet. Planteamos la hipótesis de que la utilización del móvil en horario no laboral mediatiza en parte la relación negativa entre las expectativas de disponibilidad y la desconexión psicológica. Se esperaba que la preferencia por la segmentación moderaría este efecto mediador. Por último analizamos la dirección de este efecto moderador. Los resultados confirman nuestras hipótesis y ponen de manifiesto un efecto mediador débil del uso del móvil en horario no laboral en la relación entre expectativas de disponibilidad y la desconexión psicológica. El efecto mediador, además, es mayor en personas que tienen poca preferencia por la segmentación. Se comenta la implicación práctica de los resultados.(AU)

The COVID-19 pandemic influenced the work of employees across all continents. This article presents raw data that may be used to describe how the pandemic affected the work of employees in four European countries and how it influenced their job attitudes, feelings and work performance. In total, 726 respondents from Germany, the Czech Republic, Slovakia and Italy filled out an extensive online survey and provided information about changes in their workload, work difficulty, income, social contact, work from home, task performance and organizational commitment during the pandemic, and about the risk of being infected by COVID-19 during their workday. The employees also reported their actual work performance, organizational commitment, job satisfaction, intention to leave and irritation in the time of the pandemic. To reveal factors that might help employees cope with pandemic, the respondents filled out established questionnaires measuring servant leadership of their supervisor, perceived organizational support, social support provided by colleagues, their own occupational self-efficacy, resilience, job crafting and readiness for change. The data is unique as it was collected in a specific situation during the pandemic, when the work of employees was affected by security measures and lockdown introduced by governments in countries where they worked.
ABSTRACT
The method for the analysis of vanadium in hexagonal mesoporous silica (V-HMS) catalysts using Laser Induced Breakdown Spectrometry (LIBS) was suggested. Commercially available LIBS spectrometer was calibrated with the aid of authentic V-HMS samples previously analyzed by ICP OES after microwave digestion. Deposition of the sample on the surface of adhesive tape was adopted as a sample preparation method. Strong matrix effect connected with the catalyst preparation technique (1st vanadium added in the process of HMS synthesis, 2nd already synthesised silica matrix was impregnated by vanadium) was observed. The concentration range of V in the set of nine calibration standards was 1.3-4.5% (w/w). Limit of detection was 0.13% (w/w) and it was calculated as a triple standard deviation from five replicated determinations of vanadium in the real sample with a very low vanadium concentration. Comparable results of LIBS and ED XRF were obtained if the same set of standards was used for calibration of both methods and vanadium was measured in the same type of real samples. LIBS calibration constructed using V-HMS-impregnated samples failed for measuring of V-HMS-synthesized samples. LIBS measurements seem to be strongly influenced with different chemical forms of vanadium in impregnated and synthesised samples. The combination of LIBS and ED XRF is able to provide new information about measured samples (in our case for example about procedure of catalyst preparation).
