Opis:
Competencies are a crucial factor of professional position and career development. The aim of this paper is the assessment of the competencies of people in late productive age using exploratory factor analysis. The second point is the critical review of the theory and practice on exploratory factor analysis. The empirical analysis is based on the Study of Human Capital data. The survey results confirm the necessity of the factor analysis in research in the area of human capital in the context of ageing. The constructed synthetic indicators allowed for a synthetic assessment of the competencies of Poles aged 50-59/64. The results of the conducted analysis confirm the large significance of all the 24 analysed competencies. The competencies of Poles aged 50-59/64 were decomposed into three groups: (1) soft competencies and physical fitness (2) computer skills and (3) availability and technical competencies.

Opis:
Workplace innovation enables the development and improvement of products, processes and services leading simultaneously to improvement in organisational performance. This study has the purpose of examining the factor structure of workplace innovation. Survey data, extracted from the 2014 APS employee census, comprising 3,125 engineering professionals in the Commonwealth of Australia’s departments were analysed using exploratory factor analysis (EFA) and confirmatory factor analysis (CFA). EFA returned a two-factor structure explaining 69.1% of the variance of the construct. CFA revealed that a two-factor structure was indicated as a validated model (GFI = 0.98, AGFI = 0.95, RMSEA = 0.08, RMR = 0.02, IFI = 0.98, NFI = 0.98, CFI = 0.98, and TLI = 0.96). Both factors showed good reliability of the scale (Individual creativity: α = 0.83, CR = 0.86, and AVE = 0.62; Team Innovation: α = 0.82, CR = 0.88, and AVE = 0.61). These results confirm that the two factors extracted for characterising workplace innovation included individual creativity and team innovation.

Opis:
Aim of the study: Identification of factors which determine effective communication between a doctor and a patient. Development of a tool for the evaluation of doctors’ skills of breaking bad news to patients’ relatives. Material and methods: The study was conducted with the survey method, and covered a group of 94 doctors of medicine from three hospitals in the Małopolska region in Poland. The Breaking Bad News Skills questionnaire, developed by Wioletta Szwed-Łopata and Jakub Lickiewicz, describes a doctor’s behaviour in contact with a patient’s family. Results: Exploratory factor analysis was conducted to establish the factor structure of Breaking Bad News Skills questionnaire. The scree plot was used prior to determining the number of factors. Internal consistency was evaluated with Kaiser–Meyer–Olkin (KMO) measure, which should be above 0.6, and Bartlett’s test of sphericity. The factor analysis identified five factors referring to the most characteristic types of doctors’ behaviour. These are: Communication (COM), Emotional Barriers (EMO), Partnership (PAR), Support (SUP) as well as Empathy and Compassion (EMP). The first of the constructed factors (8 items) focuses on statements concerning a doctor’s communication with a patient (COM), while the second factor (8 items) pertains to statements connected with the emotional context of breaking bad news by the physician (EMO). Next factor (5 items) includes statements about partnership (PAR). The fourth factor (5 items) concerns the ability to build a supportive environment (SUP). The last factor (8 items) comprises statements concerning partnership, refers to building a supportive environment and the doctor’ s empathy and compassion (SUP). Conclusions: Results of the Breaking Bad News Skills tool analyses indicate that it should be recommended for further scientific research and used in many areas of psychological and social practice.
Celem pracy jest identyfikacja czynników determinujących efektywną komunikację pomiędzy lekarzem i pacjentem, a także stworzenie narzędzia oceniającego umiejętności lekarzy w zakresie przekazywania złych wiadomości rodzinie pacjenta. Materiał i metody: W badaniu zastosowano metody kwestionariuszowe w grupie 94 lekarzy z trzech szpitali w Małopolsce. Kwestionariusz Przekazywania Złych Wiadomości (Breaking Bad News Skills, BBNS), autorstwa Wioletty Szwed-Łopaty i Jakuba Lickiewicza, opisuje zachowanie lekarza w kontakcie z rodziną pacjenta. Wyniki: W celu określenia struktury czynników Kwestionariusza Przekazywania Złych Wiadomości zastosowano eksploracyjną analizę czynnikową. Do określenia liczby czynników użyto kryterium wykresu osypiska. Do oceny adekwatności doboru próby do badania wykorzystano miarę Kaisera– Mayera–Olkina (KMO) oraz test sferyczności Bartletta. Analiza czynnikowa wykazała pięć czynników odwołujących się do najbardziej typowych zachowań lekarzy. Są to: Komunikacja (COM), Bariera Emocjonalna (EMO), Partnerstwo (PAR), Wsparcie (SUP) oraz Empatia i Współczucie (EMP). Pierwszy z utworzonych czynników (8 pytań) skupia twierdzenie dotyczące komunikacji lekarza z pacjentem (COM), drugi (8 pytań) koncentruje się bardziej na twierdzeniach związanych z kontekstem emocjonalnym, jaki towarzyszy lekarzowi w czasie przekazywania złych wiadomości (EMO). Kolejny czynnik (5 pytań) obejmuje twierdzenie dotyczące kontekstu o charakterze partnerskim (PAR). Czwarty czynnik (5 pytań) dotyczy budowania środowiska wspierającego (SUP). Ostatni czynnik obejmuje 4 pytania związane z empatią i współczuciem lekarza (EMP). Wnioski: Wyniki analiz statystycznych wskazują, że Kwestionariusz Przekazywania Złych Wiadomości powinien być używany w dalszych badaniach naukowych, jak również może być zastosowany w wielu obszarach praktyki psychologicznej.

Teaching, community involvement, and conducting research are the three functions of higher education institutions (HEIs). This exploration aims to develop constructs of instructors’ engagement or non-engagement in research as basis for developing a training framework. This study employed exploratory factor analysis. Eighty-four (84) instructors answered the questionnaires. The findings revealed four (4) factors of instructors’ research engagement: administrative support, recognition and promotion, motivation, and institutional requirement. It further showed instructors’ non-engagement in research could be due to four (4) factors such as time constraints, lack of experience and training, financial limitation, and lack of motivation. The scales have copious sampling adequacy and a high level of reliability. The instruments can be useful in assessing the level of instructors’ engagement and non-engagement in research.

Opis:
Conducting integrated measures within the framework of sustainable development requires an objective identification of the needs for their implementation based on the results of multifaceted analyses of many complex, interrelated factors reflecting the state of the natural environment and the economic and demographic situation. The increasing functionality of Geographic Information Systems (GIS), has made GIS databases a tool supporting the implementation of sustainable development activities. The aim of the study was to recognise the spatial variability of the level of environmental governance in the south-west region of Poland. Methods of research on multidimensional data mining techniques and geo-spatial analyses were applied, resulting in a theoretical model describing the regularities in the relationships between the analysed indicators of environmental governance. The level of environmental governance was most strongly determined by indicators concerning climate change and biodiversity.

Opis:
Conditional respect reflects a positive evaluation based on internalized normative assumptions (Reykowski). This evaluation may be operationalized in the form of verbal judgments, which enables the use of the questionnaire technique. The opinions on the conditions of gaining and losing respect for adults with disabilities, collected with the participation of 32 competent judges, enabled the development of a set of test items, indicating the dispositional orientation of conditional respect. The collected research material based on a sample of 323 respondents assessing the significance of various forms of disabled people’s activity to the increase or decrease in the respect they enjoy in social perception was subjected to exploratory factor analysis (with Varimax rotation). Scree plot analysis indicated the presence of two factors: the first one positive and the second one negative. A detailed examination of the items in the light of the theory of normative assumptions (Reykowski) revealed five categories: Individual Productivity, Individual and Collective Synergy (Factor I), as well as Individual Receptiveness and Antagonism (Factor II). The analysis of stability confirmed the repeatability of 29 items, and the internal consistency (Cronbach’s α) of the items for the identified categories of normative beliefs ranges from .73 to .83. Therefore, the CRPD-Q meets the basic validity and reliability criteria of the measurement of conditional respect for adults with disabilities – overall conditional respect and its various aspects. Finally, the instructions for estimating and interpreting the scores are presented and further challenges involved in the development of the measure are signaled.

Exploratory Structural Equation Modelling (ESEM)
Opis:
Research background: Many authors emphasize that successful human resource management (HRM) practices align with employees’ needs associated with the construct of employees’ interests. In particular, the importance of considering employees’ interests is emphasized in the process of shaping the architecture of Socially Responsible Human Resource Management (SR-HRM) systems. Purpose of the article: The aim of the article is to contribute to understanding employees’ interests by designing and validating a measure to recognize these interests. Methods: Through the use of literature sources and expert opinions, the authors developed a list of employee interests. Empirical data collected via the survey method in Poland was used to statistically verify the measurement scale. In particular, exploratory factor analysis and exploratory structural equation modelling were applied. Findings & value added: This article shows that it is important to create a comprehensive list of interests, as well as validate the research tool used. The newly developed scale has 22 items and five dimensions: support and development at the level of the enterprise, employee participation, support and development at the departmental level, employment security, working conditions and remuneration. It may be used in a variety of companies, as well as in complex research models, and developed further taking into consideration the context of other countries.

Opis:
The aim of the paper is to assess the potential for using some selected PCA-based methods to analyze the spatial diversity of crime in Poland during 2000-2017. Classical principal components analysis (PCA) deals with two-way matrices, usually taking into account objects and variables. In the case of data analyzed in the study, apart from two dimensions (objects – voivodships, variables – criminal offences), there is also the dimension of time, so the dataset can be seen as data cube: objects × variables × time. Therefore, this type of data requires the use of methods handling three-way data structures. In the paper the variability of some selected categories of criminal offences in time (2000- -2017) and space (according to voivodships) is analyzed using the between-class and the within-class principal component analysis. The advantage of these methods is, among others, the possibility of the graphical presentation of the results in two-dimensional space with the use of factorial maps.

Opis:
This paper presents results of the literature review from the field of tourism and recreation covering Polish research papers published in the years 2000–2017. The literature review concerns the main issues related to the labour market in tourism economy. This study examines publications in specialist journals, monographs, monograph chapters and a ministerial report on this topic. The aim of the literature review was to establish the evolution of the discussed topics, adopted paradigms and research perspectives. The study was conducted from two points of view, i.e. as a classic textual analysis and as an exploratory analysis performed using Statistica Data Miner software. The analysis indicated that there was a modest but growing number of publications by tourism and recreation specialists and the topics investigated by the researchers were closely related to the changes on the labour market. The subject matter evolved from issues concerning the significance of tourism in boosting demand for labour, the level and structure of demand for specialists in this sector, as well as research focused on the role of employees in efficient operation of tourism enterprises. At the beginning of the 21st century the dominant research trends were based on a positivist paradigm, quantitative structural and functional, as well as economic and spatial analyses. However, these trends were gradually replaced by an interpretative paradigm and humanistic, behavioural, sociological, and interdisciplinary approaches.
Artykuł prezentuje efekty przeglądu publikacji z zakresu turystyki i rekreacji, które ukazały się w Polsce w latach 2000–2017 i były poświęcone szeroko pojętej problematyce rynku pracy w gospodarce turystycznej. Badaniami objęto tylko opracowania zamieszczone w czasopismach specjalistycznych, monografie, rozdziały w monografiach oraz tematyczny raport ministerialny. Celem studiów literatury było ustalenie ewolucji nurtów tematycznych oraz przyjmowanych w nich paradygmatów i orientacji badawczych. Prowadzono je z dwóch perspektyw, czyli jako klasyczną analizę tekstu oraz analizę eksploracyjną z zastosowaniem programu Statisica Data Miner. Badania dowiodły, że problematyka ta cieszyła się niewielkim, ale rosnącym zainteresowaniem specjalistów z zakresu turystyki i rekreacji, a podejmowana przez nich tematyka pozostawała w ścisłej zależności z przemianami zachodzącymi na rynku pracy. Ewoluowała ona od zagadnień dotyczących znaczenia turystyki w stymulowaniu popytu na pracę oraz wielkości i struktury zapotrzebowania na specjalistów w tej branży do badań skoncentrowanych na roli pracownika w efektywnym funkcjonowaniu przedsiębiorstw turystycznych. Zmiany w nurtach badawczych skutkowały zastępowaniem dominującego na początku XXI wieku paradygmatu pozytywistycznego oraz ilościowych, strukturalno-funkcjonalnych i ekonomiczno-przestrzennych ujęć analizowanych zagadnień na paradygmat interpertatywny i ujęcia humanistyczne, behawioralne, socjologiczne oraz interdyscyplinarne.

Opis:
As spatial diversity of economic development is one of the main problems of modern economies, researchers have attempted to define the conditions and factors influencing this phenomenon. Among others, two intangible factors are suggested: human capital and social capital (Herbst ed. 2007). The primary objective of this work is a spatial and spatio-temporal analysis of the diversification of human and social capital within the Polish NUTS 3 subregions. The two detailed targets are constructing composite indicator of both of the mentioned types of capital as well as examining spatial interactions between human capital, social capital and the GNP level per capita. The large diversification of human and social capital in the Polish subregions has been confirmed. Clusters of regions with low levels of human capital have been indicated, whereas in the case of social capital a grouping of its high values was observed. The research also confirmed the positive correlation between GNP per capita and human capital, with high values of both variables in the larget cities. Additionally, there are some subregions with high levels of economic development surrounded by low levels of human and social capital (Łódź, Szczecin, Wrocław). It is possible that high level of GNPpc in these regions was the incentive causing the relocation of human capital from the neighbouring regions. The correlation between GNPpc and social capital, where significant, is of the low-high type. These subregions are located in the east and south of Poland.

Opis:
In this work, we integrated exploratory factor analysis (EFA) followed by structural equation modeling (SEM) to assess the work performance efficiency under the traffic noise environment for open shutter shopkeepers in the Indian urban context. 706 valid questionnaire responses by personal interviews in local language were collected from open shutter shopkeepers exposed to noise level (Leq) of 77 dBA for 12 to 14 hours daily. The questionnaire was prepared based on demographics, environmental conditions, and primary effects of noise pollution. Among which four common latent factors which summaries 17 questionnaire response items were obtained by exploratory factor analysis, which are “Impacts of noise” (IM), “Environmental conditions” (EC), “Personal characteristics” (PC) and “Work efficiency” (WE). The associations between the individual latent factors were studied by the structural equation model method in AMOS software. Validation of the constructed model was carried out by testing the proposed hypothesis as well as goodness-of-fit indices like Absolute fit, Incremental fit, and Parsimonious fit indices. The effect of specific latent factors derived on the work efficiency of shopkeepers in the noisy area was characterized by the path coefficients estimated in the SEM model. It was found that work performance efficiency (WE) was greatly influenced by the primary impacts of noise pollution like annoyance, stress, interference in spoken communication, which was associated with the latent factor “Impacts of noise” (IM) with a path coefficient of 0.931. The second latent factor “Environmental conditions” (EC), which was associated with parameters like ambient temperature and humidity, showed less path coefficient of 0.153. And lastly, a latent factor called “Personal characteristics” (PC) associated with age, experience, education, showed the least path coefficient of 0.05. The work efficiency of open shutter shopkeepers working in a highly noisy commercial area is profoundly affected by the prominent effects of noise pollution and least affected by ambient environmental conditions as well as their personal characteristics. The developed model clarified some casual relationships among complex systems in the study of noise exposure on individuals n tier 2 cities in the Indian context and may help other researchers to study of tier I and tier III cities.
