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.

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.

Context of the research: Research is increasingly carried out to take into account the social behavior of residents, the type of industry located in the area, and perceived preference for the place of residence. The quality of life in urban space is increasingly seen as a problem of cooperation between various stakeholders. These studies not only identify factors and sources of odor emissions, but also serve as the basis for creating systems to alert people living in areas adjacent to industrial areas or harmful and unpleasant industrial emissions. In recent years, environmental issues, particularly unpleasant sensory experiences, have been one of the most important acceptance criteria. Aim of the article: The aim of the study is to assess the impact of odor nuisance in the south-eastern part of Kraków (Płaszów) on the residents’ decision to leave their place of residence. In particular, the research goal was achieved to indicate which of the unpleasant odors may cause a change of residence, as well as to assess the degree of their impact on the decision to move, taking into account the social and demographic characteristics of residents. New in the article: The novelty of the work was the finding out of the residents’ opinions about the quality of life by accepting the place of residence, taking into account the aspect of odor nuisance. Previous studies on odor nuisance have focused on the emission of odors from individual plants. A novelty of this research is its implementation in an urban area, in which numerous industrial plants are located, with various odors emitted. Research methodology: To assess odor nuisance, a measuring tool developed in accordance with VDI 3883 guidelines was used, based on the latest research results on odor and noise nuisance. The questionnaire was developed based on German experience. Conclusions from the research: The data obtained as a result of the research allow us to state that specific smells are so burdensome that they may cause the necessity to leave the place of residence, because the respondents feel various unpleasant smells that have an adverse impact upon the quality of life that they perceive. A possible need for relocation of domiciles out of the current place of residence due to unpleasant smells would affect the perceptible, specific level of grief—the greater it is, the more attached the residents are to their current place of residence.

The fuzzy TOPSIS (The Technique for Order of Preference by Similarity to Ideal Solution) is an attractive tool for measuring complex phenomena based on uncertain data. The original version of the method assumes that the object assessments in terms of the adopted criteria are expressed as triangular fuzzy numbers. One of the crucial stages of the fuzzy TOPSIS is selecting the fuzzy conversion scale, which is used to evaluate objects in terms of the adopted criteria. The choice of a fuzzy conversion scale may influence the results of the fuzzy TOPSIS. There is no uniform approach in constructing and selecting the fuzzy conversion scale for the fuzzy TOPSIS. The choice is subjective and made by researchers. Therefore, the aim of the article is to present a new, objective approach to the construction of fuzzy conversion scales based on Item Response Theory (IRT) models. The following models were used in the construction of fuzzy conversion scales: Polychoric Correlation Model (PM), Polytomous Rasch Model (PRM), Rating Scale Model (RSM), Partial Credit Model (PCM), Generalized Partial Credit Model (GPCM), Graded Response Model (GRM), Nominal Response Model (NRM). The usefulness of the proposed approach is presented on the example of the analysis of a survey’s results on measuring the quality of professional life of inhabitants of selected communes in Poland. The obtained results indicate that the choice of the fuzzy conversion scale has a large impact on the closeness coefficient values. A large difference was also observed in the spreads of triangular fuzzy numbers between scales based on IRT models and those used in the literature on the subject. The use of the fuzzy TOPSIS with fuzzy conversion scales built based on PRM, RSM, PCM, GPCM, and GRM models gives results with a greater range of variability than in the case of fuzzy conversion scales used in empirical research.
