Opis:
Enterprise innovation is currently becoming a recognized factor of the competitiveness, survival, and development of companies in the market economy. Managers still need recommendations on ways of stimulating the growth of innovation in their companies. The objective of this paper is to identify the strategic factors of enterprise innovativeness in the area of technology, defined as the most important internal factors positively impacting the innovativeness of enterprises in a strategic perspective. Empirical studies were conducted using the Computer-Assisted Web Interview (CAWI) method on a purposive sample of N = 180 small and medium-sized innovative industrial processing enterprises in Poland. Data analysis was performed using Exploratory Factor Analysis within the Confirmatory Factor Analysis framework (E-CFA) and Structural Equation Modeling (SEM). Empirical research shows that the strategic factor of enterprise innovativeness in the area of technology is technological activity. A technologically active company should (1) possess a modern machinery stock, (2) conduct systematic technological audits, and (3) maintain close technical cooperation with the suppliers of raw materials, consumables, and intermediates. The implementation of the indicated recommendations by managers should lead to increased innovativeness of small and medium-sized industrial companies. The author recommends the use of the presented research procedure and data analysis methods in further studies.

Opis:
This study investigated entrepreneurial intention among graduate students of USM**** Engineering Campus. Applying the Theory of Planned Behavior (TPB; Ajzen), we examined the empirical model of entrepreneurial intention determinants. Although research has been conducted in entrepreneurial intention, limited study has been done among Iranian graduate students who are studying abroad. This research aims to fill this gap using Entrepreneurial Intention Questionnaire (EIQ, version 3.1). Accordingly, a survey study was applied and Iranian graduate students of the USM Engineering Campus were studied using the census method. The authors propose an empirical model and tested its reliability and validity using structural equation modeling. Data was analyzed using Spss16 and Amos18 software. Results revealed that the level of knowledge about business sources of assistance for entrepreneurs in addition to components of the TPB, affected entrepreneurial intention. Empirical model ‘s goodness of fit indices indicated good model fit χ2=1.047, df=2, probability 0.592; NFI= 0.981; CFI= 1.000; RMSEA=0.000). It seems that current empirical model could be a guide for future research on this important topic.

Opis:
Research background: During the COVID-19 pandemic, public sector entities encountered extraordinary difficulties in maintaining the delivery of public services. They were ill-equipped to operate in the unpredictable circumstances of the pandemic, causing a significant impact on the accessibility and quality of public services. This scenario also highlighted the importance of the resilience of the public sector, which entails an organization's capacity to function in a crisis setting and uncover opportunities that might not have been evident during normal circumstances. Purpose of the article: This study aims to assess development trends within public sector resilience and their impact on the quality of public services. As resilience is realized through a three-phase prism - i.e., Planning, Adaptation, and Enhanced Learning - we hypothesize that Adaptation is endogenously interrelated with Planning and positively affects Enhanced Learning, which in turn positively impacts Service Quality. Methods: Two successive surveys were carried out to examine the links between organizational resilience and Service Quality in the public sector. The first involved interviewing 401 senior managers of the organizations that provide public services in Lithuania to assess their level of organizational resilience. The second survey involved questioning individuals aged 18 and above who had used the services of the previously surveyed organizations. In total, 3,609 public service users were interviewed to gather data on Service Quality. Structural equation modeling was performed to analyze the data collected. Findings & value added: The results of structural equation modeling revealed that Enhanced Learning positively and significantly affects Service Quality. The findings of this study suggest that the bounce-back stage of organizational resilience, i.e., Adaptation, indirectly affects Service Quality through the bounce-forward stage, i.e., Enhanced Learning. Thus, Enhanced Learning acts both as an accelerator of Service Quality and as a moderator of the effect that other stages of organizational resilience have on Service Quality. The primary contribution of this article is its discovery that Service Quality develops from Enhanced Learning, implying that the optimal approach to service provision is based on both newly acquired knowledge and experience gained during challenging times. This enables organizations to transform their service delivery in response to the realities of changing circumstances, thereby creating opportunities to prepare for future challenges from the standpoint of a new equilibrium.

Opis:
Research background: There is currently a need for empirical research regarding the validity of specific work environment model elements supported by strong statistical evidence. The amount of research conducted in this field has been particularly limited in Central-Eastern Europe. The desire to fill in these gaps was at least in part responsible for the uniqueness of the research approach and its differences from previous similar studies. Purpose of the article: The purpose of this study was to examine factors affecting employee engagement and to examine their relationship with each other using Visegrad countries as an example. Methods: The initial data is taken from the fourth European Company Survey (2019) for management respondents. After data cleaning, the sample sizes for Czechia, Hungary Poland, and Slovakia are N(CZ)=904, N(HU)=682, N(PL)=511, and N(SK)=361, respectively. As a result of the exploratory factor analysis (EFA), the following five dimensions were identified for this research: (1) inclusiveness, (2) empowerment, (3) work autonomy, (4) organizational learning environment, and (5) work engagement. An analysis of structural equation modeling (SEM) was conducted to determine the links that exist among these dimensions of a constructive work environment. Findings & value added: The structural model indicates that inclusiveness and empowerment have a significant positive impact on work engagement in all the countries examined. Inclusiveness was the strongest predictor of work engagement, followed by empowerment. Both of the two other predictors in the model (workplace autonomy and organizational learning environment) generally had less or no effect on employee engagement. The present study extends recent literature on work engagement by empirically validating the influence of workplace environment-related factors, as well as providing useful organizational policy recommendations for managers.

In this paper we conduct a three step analysis of business tendency survey data in order to establish (1) common factors driving responses to groups of questions in the business tendency survey conducted among firms in the manufacturing industry in Poland, (2) factors responsible for respondents’ answers regarding assessments (present) and expectations (future), and (3) interrelations between current assessments and expectations. We start by performing a check of the factor structure with multi-group confirmatory factor analysis (MGCFA) models in order to establish common factors responsible for sets of answers in the area of assessments and expectations, respectively. Then, we proceed with structural equation modeling (SEM) framework in order to define period specific relations between the factors. With the final structural model we show that most answers in the area of current assessments and expectations of companies are in line with the stylised facts. We also demonstrate that the companies’ response pattern did not change during the financial crisis.

Opis:
The purpose of the analysis was to verify a model which included connections among variables crucial to the child’s upbringing process. These variables were: the discrepancy between the parental goal and child’s actual state, the difficulty experienced by the parent (which following Gurycka [1990] is understood as psychological stress) and the child’s representation in the parent’s mind. It was hypothesized that the discrepancy between the parental goal and child’s actual state might determine the diffi culty experienced by the parent. What is more, this difficulty experience might start the process of shaping the child’s negative representation in the parent’s mind. The purpose of the analysis was to discover connections among the constructs in the net of common relations. A structural equation model was used for this purpose. The calculations were conducted with the help of the IMB AMOS program. The research was conducted on a sample of 100 people, parents of children aged 3 to 10 . The results obtained confirm the suggested connections among the variables. The results confirm the good fit of the model.

Research problem analysed in the paper concentrates on the impact of the choice of scale on the the goodness of fit of the Structural Equation Model. For that purpose the primary research tool were built and used for conducting two rounds of research. In the first round two groups of respondents were given two different questionaries dealing with the same research problem (same set of research questions) but using different, 5 or 10 point scales. After one week the same groups of respondents were asked again to assess the research problem by using different type of scale. Obtained empirical data were used to build the structural equation models (for 5 and 10 point scales) of the analysed research problem. Thanks to the collected empirical data it was possible to analyze the impact of the choice of scale on internal (AVE, Cronbach’s Alfa, Composite Reliability) and external (R2) goodness of fit of the model.

The paper proposes a theoretical model to assess the factors affecting students’ satisfaction of their university and their future behavioral intentions. The proposed model was validated by empirical or case research, applied at three Colombian universities (public and private) in Cartagena. A 19-item questionnaire was given to a random sample of 400 students, and was solved by the Structural Equation Modeling (SEM). Results showed that the students’ perceptions of the universities analyzed affected their satisfaction level and this, in turn, affected their future intentions. Perceived value pricing did not have a significant effect on satisfaction. The model was validated using the most common fit indices. The results presented a statistically valid model, whose main result is the identification of a significant causal effect among the students’ perceptions, satisfaction and future behavioral intentions in the universities analyzed. There was not a significant difference in results between the public and private universities.

Entrepreneurs running their businesses usually pursue goals associated with work and family functioning. The efficiency of goal realization in these two areas of activity varies and may depend on balance between the two domains. The study aimed to answer the question of how interplays between the work and family domains (work-to-family conflict, family-to-work conflict, work-to-family facilitation, and family-to-work facilitation) were related to the realization of work and family goals in entrepreneurs. It also tested if sex was a moderator of these relationships. A total of 246 entrepreneurs participated in the study; they were married or in stable non-marital relationships. Structural equation modeling showed that family-to-work conflict is negatively related to work goal realization and family goal realization, and work-to-family facilitation is positively related to family goal realization. Sex does not moderate the relationships analyzed. The study provides insight into the relationships of conflict and facilitation to goal realization in people running their businesses.

The present study aims to widen the existing literature by discovering potential determining factors at selected ecotourism destinations, primarily involving Bako, Niah, Kubah, Gunung Gading and Gunung Mulu National Parks. A closed questionnaire was answered by 188 respondents. Preliminary analyses were performed and partial least square structural equation modeling was employed as the analytical measure, thus discovering the significant role of destination resource constructs in the enhancement of ecotourism competitiveness in Sarawak, Malaysia. The statistical findings of the current work revealed that endowed resources (natural resources and cultural heritage attractions), created resources (range of activities) as well as supporting resources (destination accessibility and quality of tourism services) lead to enhanced tourism destination competitiveness. The research adds to the growing body of knowledge examining the perspectives of tourists towards the determining factors of destination competitiveness, while providing meaningful insights for industry actors, thus enabling effective planning of management and development. The present work offers empirical evidence that gives information for industry stakeholders, including business operators, policy makers and tourism planners in order for natural tourism destinations to prosper.

Aim/purpose – This study evaluates the influence of opportunity-enhancing human resource practices on radical innovation and examines the mediating role of exploration capability in this relationship. Design/methodology/approach – Hypotheses were formulated to determine the relationship between opportunity-enhancing human resource practices and radical innovation, as well as the mediating role that exploration capability plays in this relationship. These were tested in 168 Colombian companies from the telecommunications and chemical-pharmaceutical sectors using Structural Equation Modeling (SEM) via the Partial Least Squares (PLS) technique. Findings – The study indicates that opportunity-enhancing human resource practices positively and significantly influence radical innovation. In addition, this relationship is mediated by exploration capability. Research implications/limitations – Organizations should implement opportunity-enhancing human resource practices to support radical innovation development. These practices provide employees with opportunities to explore relevant knowledge and technologies necessary for radical innovation. Originality/value/contribution – Identifying and testing a specific group of human resource practices that facilitate radical innovation is one of the most significant gaps in the scientific literature on the relationship between human resource practices and innovation. According to this article, opportunity-enhancing human resource practices facilitate radical innovation in organizations. Furthermore, previous research has not examined the relationship between opportunity-enhancing human resource practices, exploration capability, and radical innovation.

W artykule podjęta została problematyka zależności między odpowiedziami respondentów w ramach kwestionariusza badania kondycji gospodarstw domowych w Polsce. Wyróżnione zostały cztery obszary, w których respondenci udzielają odpowiedzi: bieżąca sytuacja gospodarstwa domowego (BSGD), bieżąca sytuacja gospodarki (BSG), prognozowana sytuacja gospodarstwa domowego (PSGD) i prognozowana sytuacja gospodarki (PSG). Dla każdego z obszarów z wykorzystaniem konfirmacyjnej analizy czynnikowej dla wielu grup dokonano estymacji modelu pomiarowego. Pokazano, że dla trzech z czterech obszarów (z wyjątkiem BSGD) możliwe jest wyselekcjonowanie pytań, które w spójny sposób będą mierzyły analizowany obszar. Dla obszaru BSGD wybrano zaś jedno pytanie wskaźnikowe opisujące ten obszar. W następnym kroku przeprowadzono estymację modelu strukturalnego, tym samym weryfikując związki między zmiennymi ukrytymi (obszarami). Wykazano, że odpowiedzi gospodarstw domowych na pytania dotyczące przyszłej sytuacji ich gospodarstwa domowego są powiązane z odpowiedziami udzielanymi w każdym z pozostałych trzech obszarów. Pokazano silne przełożenie między odpowiedziami dotyczącymi oceny bieżącej sytuacji gospodarczej i dotyczącymi prognozy przyszłej sytuacji gospodarczej oraz odpowiedziami dotyczącymi oceny bieżącej sytuacji gospodarczej i tymi, które dotyczą oceny bieżącej sytuacji gospodarstwa domowego. W toku prowadzonej analizy udało się również stwierdzić, że na poziomie gospodarstwa domowego (respondenta) zmiana opinii w obszarze oceny bieżącej sytuacji gospodarczej przekłada się w każdym momencie analizy na taką samą zmianę opinii w pozostałych obszarach, co związane było z możliwością estymacji modelu strukturalnego z narzuconymi warunkami równości ładunków czynnikowych.
In this paper, an issue of interdependence between the responses of respondents in the State of the Households survey in Poland was investigated. Four areas were proposed in which respondents provide answers to the questionnaire: current situation of the household (CHS), current situation of the economy (CES), forecasted situation of the household (FSH) and forecasted economic situation (FSE). For each of the areas with application of the multi-group confirmatory factor analysis a measurement model was estimated. It was shown that for three of the four areas (except CHS) it is possible to select a set of questions measuring consistently analyzed area. For CHS a single question indicator describing the area was proposed. In the following step a structural model was estimated. Thus it was possible to verify the relationships between latent variables (areas). It was shown that households responses to questions concerning FSH are interrelated with responses in each of the other three areas. Strong interdependence between individual respondents’ answers in the areas of (1) CES and FSE, but also (2) CES and CHS was identified. In the course of that study it was also possible to conclude that at the household level a change in opinion in the area of CES affects in all periods with the same magnitude opinions in the other areas. It was confirmed by estimating the structural model with the imposed conditions of equal factor loadings.

The aim of this study was to describe and characterize the relationships between yielding factors and grain yield per doubled haploid (DH) plant of spring barley as well as relation between yield components and duration of each stage of plant development. To describe these relations structure equation modeling was used. The study included plants of doubled haploid spring barley lines (Hordeum vulgare L.) derived from tworowed form of Scarlett cultivar. The SAS® system was used to analyze the model of relationships between grain yield per plant and yield components. Our results indicate that the number of spikes per plant and grain yield per spike had a direct and decisive influence on the grain yield of the investigated DH plants of spring barley. Based on the path model analysis it was found that the most important factor determining grain yield per DH plants of spring barley was the number of spikes per plant and the duration of tillering and shooting stages.

Opis:
Migrations form the size and structure of human resources in regions. For that reason they have not only a demographic but also a social and economic character. The existing research is often not enough due to a spatial, temporary and also a multidimensional character of this occurrence. The subject of this paper is to apply Structural Equation Modeling (SEM) concept for analysing the population migration phenomena considering the gravity model. This approach allows describing the social and economic situation in regions considering a set of correlated variables and it also allows determining its influence on migration flows. The first part of the article describes the construction and interpretation of the gravity model and the concept of the SEM model. In the second part the adopted research procedure and the research scope are presented. In the last part, the results of the investigation are explained. The strength and direction of the impact of the socio-economic development on the migration flows between subregions (NUTS 3) in Poland in the years 2008-2010 are discussed.
Migracje kształtują wielkość i strukturę zasobów ludzkich w regionach, mają więc wymiar nie tylko demograficzny, ale także społeczno-gospodarczy. Prowadzone badania obejmujące najczęściej analizę wskaźnikową, są często niewystarczające ze względu na przestrzenno-czasowy i wielowymiarowy charakter tego zjawiska. Celem artykułu jest propozycja zastosowania w analizie migracji metodologii SEM z uwzględnieniem modelu grawitacji. Takie podejście pozwala opisać sytuację społeczno-ekonomiczną regionów z wykorzystaniem zmiennych skorelowanych, a także określić jej wpływ na przepływy migracyjne. W pierwszej części artykułu omówiona jest konstrukcja i interpretacja modelu grawitacji oraz koncepcja modelu SEM. W drugiej części omówiono przyjętą procedurę badawczą oraz zakres badań. W ostatniej części zaprezentowano wyniki prowadzonej analizy. Określono siłę i kierunek oddziaływania poziomu rozwoju społeczno-ekonomicznego na przepływy migracyjne między podregionami (NUTS 3) w Polsce w latach 2008-2010.
