Aims. The aim of the study was to assess the occurrence and intensity of musculoskeletal pain as a risk factor for reduced work ability. Methods. In total, 1449 workers participated in the study, 64% were younger workers (<45 years old, M 31.4); 36% were ageing workers (≥45 years old, M 50.3
), Their health condition was established on the basis of (a) subjective feeling of health on a 5-point scale, (b) pain in 6 parts of the body in the past year; and (c) intensity of pain on a 100-mm visual analogue scale (VAS). Work ability was assessed with the subjective work ability index (WAI). Results. The results of the study showed that although in the both groups, i.e., younger and ageing workers, the occurrence and intensity of pain in the hands/wrists, neck and lower back were a significant factor which decreased WAI, in ageing workers only the occurrence of pain in the lower back generated higher risk factors for reduced work ability (WAI < 37). Conclusions. Improving physical and psychosocial working conditions to reduce musculoskeletal complaints, and identifying individuals with such complaints are important in increasing workers' work ability and thus extending their occupational activity.ageing reduced work ability musculoskeletal disorders pain intensity
The growing impact of consumption on the environment has been attracting much attention from academics for the last couple of decades and has caused inquiries into the antecedents of responsible consumption. Previous studies focused on analyzing different antecedents of responsible consumption in various areas and contexts. However, very few studies investigated the antecedents of responsible consumption in the energy sector, and only a few referred to emerging European countries. The aim of the paper is to examine the effect of environmental awareness on responsible energy consumption. Data for this study have been collected using the survey methodology. A total of 1407 households were selected as a sample for the CAWI methods of gathering data. The territory of the study population is Poland. The methodology of research involves several measurement scales of theoretical constructs. The constructs′ reliability coefficients, as well as discriminant and convergent validity indices, showed an adequate level of measurement quality. Based on reliable and valid latent variables, the comparative analysis of mediated path models with moderated mediation is estimated. Structural causal modeling with d-separation check and sensitivity analysis of indirect causal paths is applied to test the causal research hypothesis under study. The research results confirm the significant mediational role of mobilizing attitude and environmental awareness in explaining relationships between perceived consumer effectiveness and energy efficiency and curtailment behaviors.
In the process of sample selection, an important issue is the relationship between sample size and the type and complexity of the statistical model, which is the basis for testing research hypotheses. The paper presents methodological aspects of sample size determination in multilevel structural equation modelling (SEM) in the analysis of satisfaction with the banking products in Poland. The multilevel SEM results from the necessity to take into account both the sample size at the level of individual respondents, as well as at the higher level of analysis and the intraclass correlation coefficient. A comparison of factor loading bias based on the Monte Carlo simulation is made for different cluster sizes and the number of clusters.
This study’s aim is to determine the consistency of student opinions regarding the importance of individual skills in three areas—people, practice, and perspective—with expert assessment. The study group consisted of five-year students accredited by IPMA Poland. The team of experts was comprised of recruiters, project management lecturers, assessors, and information technology (IT) industry project managers. Our research shows divergences in the approach to key competence that a project manager should have. This is understandable, given the specifics of the comparison. However, the analysis that has been conducted and presented will allow the curricula to be revised. The subsequent evaluation of curricula should address the changes in the labor market. Education should provide key competences, especially as modern project management requires a full spectrum of competences and approaches. Besides experience, project management is the most frequently pursued competence that is required in terms of staff recruitment criteria. The research resulting figures may be useful for recruiters, certification institutions, and universities.
