Opis:
The urban freight transport (UFT) is an important component of the urban logistics. It represents a driving force for the economic dynamics and attractiveness of a city. It can be treated as all movements of goods necessary for the economic activities, the institutions and the residents of urban life. Through, it faces with problems relating to the congestion, unsafety, atmospheric and noise pollution that constrain its performance and hinder its development. This performance is a complex subject on which a great deal of research has emerged in the last decade. Accordingly, this paper aims to develop a model for assessing the performance of the UFT. The objective is to identify the determinants of the performance of the urban freight transport and measure the impact of each factor. Therefore the first part of this article concerns the elaboration of the model and the formulation of the hypotheses. First, an overview of the factors that could influence the performance of the UFT was identified based on a literature review. The result of this step allowed to model, by mobilizing the GRAI grid (Graph of results and interrelated activities), the UFT system in order to release the decisional links between these factors. Then, the grid will be decomposed into hypotheses explaining the relations between the factors and the performance of the UFT. The formulation of each hypothesis will be based on all the theoretical works that have treated it. The second part includes the empirical study to test the model using the partial least squares (PLS) analysis. Therefore, we conducted a survey among managers and users of the UFT in the city of Fez. A hypothetico-deductive approach has been used with a sequential methodological complementarity between qualitative analysis for exploratory purposes and the support of quantitative analysis for confirmation. The results of the test, confirm a significant influence of the identified factors on the UFT performance. The practical scope of this paper is to provide a decision-making framework for urban management department explaining the impact of these factors on the UFT performance.

Opis:
Anaerobic digestion is a complex, multi-step biological process. Control of this process can be carried out by analyzing the parameters of dry matter, organic matter and the dry matter concentration of volatile fatty acids (VFA). The aim of the study is to assess the possibility of using near-infrared spectroscopy in the construction of calibration models of dry matter content in the fermenting mixture of substrates. The starting material included the test obtained from the pulp digestion process. The fermentation process uses mixed pulp rumble (22% dry matter content), ground corn (34.5% dry matter content) and bovine manure (3.21% dry matter content). For the obtained samples an acquisition of spectral absorbance spectra by the transmission in the wavelength range of 400 - 2170 nm was effected. These data were used to build the PLS calibration model spectrophotometer intended for the prediction of dry matter content of the substrate. The model with the best fit to the spectral data was obtained for the spectral range of 900 - 1300 nm. He is characterized by a coefficient of determination R2 of 0.95 and an error determination RMSECV ratio of 0.56 g.
Fermentacja beztlenowa jest złożonym, wieloetapowym procesem biologicznym. Kontrola tego procesu może odbywać się poprzez analizowanie parametrów zawartości materii suchej, suchej materii organicznej oraz stężenia lotnych kwasów tłuszczowych (LKT). Celem pracy jest dokonanie oceny możliwości zastosowania spektroskopii bliskiej podczerwieni w zakresie budowy modeli kalibracyjnych zawartości materii suchej w fermentującej mieszance substratów. Materiał wyjściowy do badań stanowiła pozyskana z procesu fermentacji pulpa. W procesie fermentacji wykorzystano zmieszane wysłodki burczane (22% zawartości materii suchej), rozdrobnione ziarno kukurydzy (34,5% zawartości materii suchej) i gnojowicę bydlęcą (3,21% zawartości materii suchej). Dla pozyskanych próbek dokonano akwizycji widm spektralnych absorbancji metodą transmisyjną w zakresie długości fali 400-2170 nm. Dane te wykorzystano do budowy modeli kalibracyjnych PLS spektrofotometru przeznaczonego do predykcji zawartości materii suchej w substracie. Model o najlepszym dopasowaniu do danych spektralnych uzyskano dla zakresu spektralnego 900-1300 nm. Charakteryzował się on współczynnikiem determinacji R2 na poziomie 0,95 oraz błędem oznaczenia RMSECV wynoszącym 0,56 g.

Pulp and paper industries have provided great research opportunities to control systems. The objective of this study was to investigate the relationships between 80 process variables of CMP tower and stock preparation, and 17 newsprint quality properties in Mazandaran Wood and Paper Industries (MWPI). After the preparation of two suitable data series considering the time needed for pulp to paper, the relations between process dependent and newsprint independent variables were determined using partial least squares (PLS) regression. As a result, two PLS models were developed. The first model with 4 latent vectors categorized and related CMP tower variables and the second one, through 8 latent vectors connected stock preparation variables with paper properties. PLS regression coefficients determined how much the most influencing process variables impact each paper properties.

Opis:
W pracy podjęto próbę budowy modelu kalibracyjnego dla spektrometru VIS-NIR przeznaczonego do oznaczania koncentracji deoksyniwalenolu (DON) w ziarnie pszenicy ozimej już na etapie zbioru kombajnowego. W tym celu podczas żniw w sezonie 2011 zgromadzono w warunkach polowych materiał badawczy w postaci 14,5 tys. widm spektralnych absorpcji promieniowania oraz 283 prób ziarna. Niska koncentracja deoksyniwalenolu w naturalnych próbach ziarna nie pozwoliła na zbudowanie modelu kalibracyjnego. Dlatego opracowane modele PLS (R2≈0,9; RMSECV≈3 – 4 mg/kg) powstały w oparciu o 60 prób przygotowanych w warunkach laboratoryjnych. Zbiór modelowy złożony z prób o koncentracji DON w przedziale od 0 do 32 mg/kg został dodatkowo uzupełniony wynikami uzyskanymi dla 58 prób z naturalnych upraw. Walidacja modeli kalibracyjnych przeprowadzona w oparciu o widma spektralne zarejestrowane w warunkach polowych wykazała wyższą, jednak nadal niewystarczającą dokładność predykcji koncentracji DON za pomocą modelu zbudowanego w oparciu o oba zbiory prób. Pracę zrealizowano w ramach projektu rozwojowego nr R12 0073 06 pt: „Opracowanie i walidacja technologii rozdziału strumienia ziarna podczas selektywnego zbioru zbóż” finansowanego przez MNiSW.
The study is an attempt to build the calibration model for the VIS-NIR spectrometer used for measuring deoxynivalenol (DON) concentration in winter wheat grain at the stage of combine harvesting. In order to achieve this goal during the harvest season of 2011 the research material of 14.5 thousand radiation absorption spectrums and 283 grain samples was collected in field conditions. The low concentration of deoxynivalenol in natural grain samples did not allow a construction of the calibration model. Therefore, the PLS models (R2≈0.9; RMSECV≈3–4 mg•kg-1) were developed on the basis of 60 samples prepared in laboratory conditions. The model set, which consisted of samples with the DON concentration of 0-32 mg•kg-1, was additionally supplemented with the results obtained for 58 samples from organic farming. The models were validated on the basis of the spectrums recorded in field conditions. The accuracy of prediction of the DON concentration by means of the model constructed on the basis of both sample collections was higher, but it was still insufficient. The study was a part of the development project No. R12 0073 06 entitled "Development and validation of the technology for separation grain stream during cereals selective harvesting ", financed by the Polish Ministry of Science and Higher Education.

Opis:
The aim of the research is to identify the strength and direction of the development of the relationship between formal and informal institutions and to assess the institutional equilibrium of modern economies. The structural equations modelling based on partial least squares (SEM-PLS) is applied to achieve the purpose of the article. It is an econometric method that allows the measurement and analysis of the dependencies between latent variables (measures that cannot be directly observed). The study included 27 EU economies and the research period covered the years 2008 and 2018. The results of the study demonstrate that the quality of informal institutions strongly, positively determines the quality of formal institutions. The conducted analyses indicate that modern economies are diversified in terms of the quality of informal and formal institutions and, consequently, in institutional equilibrium. Considerable institutional disparities also translate into a large diversification in economic development. The article proposes a different meaning of institutional equilibrium, understood as the achieved state of institutional structure characterised by high quality informal institutions which interact with each other to improve the efficiency of formal institutions. The article presents a comprehensive model of the institutional structure and a unique method of measuring institutional equilibrium.

Opis:
The last decade has seen a distinct increase in the frequency of the appearance of virtual teams within contemporary organizations. As knowledge sharing within the virtual team leads to better team performance, a deeper understanding of enabling organizational capabilities is highly relevant to both researchers and managers. Therefore, in this paper we focus on the concept of "internal change agent support". More specifically, we use a qualitative research design to study the role of internal agent support within the relationship between knowledge sharing and virtual team performance. A theoretical model was built and verified by means of structural equation modelling (PLS-SEM). The authors found that internal change agent support has a moderating effect on relationship between knowledge sharing and the virtual team performance and the knowledge sharing within the virtual team influences positively virtual team performance. These results add to the emerging academic discussion on continuous change management within dispersed teams. Our findings are also relevant to managerial practice as they suggest how to facilitate the process of knowledge sharing in a team, thus improving its efficiency.

Purpose The aim of the work presented in this paper was the construction of a regression model describing the relationship between the experimentally determined value of the maximum temperature observed during the coal mine waste fire and physico-chemical parameters characterizing the coal mine waste. Methods The model was constructed with the application of the Partial Least Squares method. The experimental data analysed was acquired through the use of a laboratory test stand with a fixed bed reactor and analytical method of gas chromatography. Results The constructed model was characterized by a good fit of the data used in its construction and the strong predictive ability for the new data. It illustrated the significant impact of the content of H and Fe2O3 and trace elements: Co, Cu, Pb, Sr, V and Zn in a sample on the value of the maximum temperature reached during the fire of coal mine waste. Practical implications The practical importance of the work presented is clear in the light of the role of coal in the Polish economy and environmental aspects related to coal mining and the coal-based energy sector, in particularly to coal waste disposal and utilization. The model constructed contributes to the development of methods of self-ignition and fire risk assessment on coal waste dumps by determining the relationship between waste dump fire occurrence, the temperature observed during the fire and the physicochemical parameters characterizing the coal mine waste. Originality/ value The novelty of the study presented in the paper consists in both finding the relationships modelled and the data extraction methods applied in the research field concerned.

Research background: The COVID-19 pandemic has affected higher education globally and disrupted its usual activities, according to differing perspectives. The ability to adapt to online activities was an important factor for many researchers during the pandemic period. Purpose of the article: In this article, the authors are studying the ability of the students to adapt to online activities, and also the direct and indirect effect on their academic performances. Methods: The data was collected with a questionnaire and the respondents are students from Romanian Universities. The analysis was made with an econometric model by using the PLS-SEM methodology. The goal of the paper was to find and analyse the factors used to perform academic online activities during the pandemic period. Findings & value added: The results of the paper validate the research hypotheses formulated in the introductory part and confirm that the students' academic performances are a direct result of many factors, such as: system parameters, personal demand, personal commitment, and regulatory environment. The identification of the exogenous variables with significant impact on the students' performances through online activities could help the management of the universities to implement the positive aspects and to reward them for their efforts while preventing from resilience to change. The higher education system has to acknowledge that flexible online learning opportunities are needed by students to fit their coursework around their employment and family responsibilities.

The study entails an examination of the factors needed for the emergence of business innovation, in the context of a developing economy, based on representative data from the Global Entrepreneurship Monitor 2021. Drawing on the theories in the literature, the impact mechanism of the entrepreneurial innovation development in our model has been assumed to involve a three-sided impact. The study builds on the entrepreneurial side effects, based on the classical Schumpeterian theory as well as incorporating the enterprises’ productive-side effects into the model, defining the model as resultant from socioeconomic macrocontext effects. The analysis of our model has been tested and analyzed using partial least squares - structural equation modeling and the necessary condition analysis. Our results show that business innovation requires not one factor, but a combination of factors. The system needs visionary entrepreneurs, who can stimulate innovation, along the concept of sustainability. An economically prosperous business with international connections which views challenges as opportunities, however, also constitutes an important factor providing proper framework for new products and services. Adequacy of the socio-economic macro-context is essential as well, as it too contributes to the development of entrepreneurship and thus to the creation of entrepreneurial innovation.

The aim of this paper is to measure social capital and determine its effect on economic development across thirty five European economies from 2017 to 2020. Partial least squares structural equation modelling (PLS-SEM) was applied to measure and identify the relationship between latent (directly unobservable) variables. Social trust was found to be more strongly determined by interpersonal trust than by trust in organisations. Furthermore, social trust was also found to be the most important component of the overall measure of social capital. The latent variable representing social interaction and attitudes was found to be less important in the formation of social capital. Finally, a strong positive and statistically significant relationship was found between social capital and economic development.
Celem artykułu jest pomiar kapitału społecznego oraz określenie jego oddziaływania na rozwój gospodarczy wybranych gospodarek europejskich w latach 2017–2020. W pracy wykorzystano metodę modelowania równań strukturalnych z wykorzystaniem cząstkowych najmniejszych kwadratów (PLS-SEM), która umożliwia pomiar oraz identyfikację związków pomiędzy zmiennymi ukrytymi (bezpośrednio nieobserwowalnymi). Ustalono, że zaufanie społeczne jest bardziej determinowane przez zaufanie interpersonalne niż przez zaufanie względem organizacji. Ponadto stwierdzono, że zaufanie społeczne jest najważniejszym elementem ogólnej miary kapitału społecznego. Mniej ważnym w formowaniu tej zmiennej okazała się zmienna społecznych interakcji i postaw. Ustalono także, że pomiędzy zmiennymi kapitału społecznego i rozwoju gospodarczego występuje silny dodatni i istotny statystycznie związek.

Research background: The research has two objectives and employs a serial mediation approach. First, using the general strain theory, it examines the mediating role of negative feelings and impact of economic adversity on people's risk tolerance and prudent financial behavior. The second is determining the various categories' variations according to age. Purpose of the article: The study's main objective is to evaluate financial behaviour of people with lower and medium incomes after the second wave of COVID-19 in India, and to contribute to the body of knowledge on general strain theory. Methods: The study examined the proposed framework and tested the serial mediation model based on the general strain theory used as a survey method for data collection, targeting lower and middle-income individuals in India's most populated state. The study applied PLS-SEM to test the framed hypotheses. Furthermore, the Kruskal Wallis test was applied to identify the difference in the various groups classified based on age. Findings & value added: The results reveal that economic hardship significantly influences improved financial behavior. Risk aversion attitude, loneliness, and depression mediate the relationship between economic hardship and financial behavior. Moreover, the study found quite a few significant differences between the different age groups. The present study will add to the existing literature on financial behavior under the scope of general strain theory and probably be among the few that test general strain theory with financial variables impact on lower and middle-income group individuals from a developing nation in post-COVID-19 period.

Research background: Innovations are introduced by competitive companies. One of the most common methods, increasingly used by companies, is organizing clusters or cluster initiatives operating within a specialized sector, competing with each other, exploiting the potential of cooperation and its impact on creating new business ideas. However, these efforts could be unviable due to the lack of an effective leader of the group. One should underline a crucial role of the leader in such an organized network, since the leader makes improvements and takes initiatives for all the network and its partners. These concepts prompt us to undertake the research on the role of clusters? characteristics on enhancing willingness to innovate in general. This study aims to point out the main characteristics of clusters and to investigate their impact on companies? innovativeness. The main problem to address is the magnitude of specific effects that might boost introducing new solutions in firms? networks. Purpose of the article: The purpose of this study is to investigate the impact of factors describing cluster environment (characteristics like cooperation within clusters and beyond them, incentives of a leader, and localization factors) that might affect the innovativeness of companies. Methods: The authors collected data using questionnaire. This type of primary source enables the authors to construct a model consisting of latent variables such as incentives of coordinator of cluster or cluster initiative, cooperation of firms with local authorities, cooperation between entrepreneurs, or localization. The results are subject to the Structural Equation Modelling (SEM) analysis. Findings & value added: The conducted analysis leads to several findings. Firstly, incentives provided by the cluster coordinator enable companies to increase the willingness to introduce innovations in general. Secondly, however, the influence of other cluster characteristics on the propensity to innovate for firms functioning within specific Polish business clusters is scant. These findings point to the fact that actions leading to assign the official coordinator of a cluster need to be done, as it should result in better flow of knowledge, more symmetric information among companies within cluster, and more productive and innovative way of functioning firms in general. Regarding innovation clusters (and regional innovation systems), these actions need to be supported by forming policy on regional level, because effective clusters would induce more competitive regional economy in long-term scenario.

Opis:
Research background: In the private sector and on social media, corporate emotional interaction has lately become a hot topic. In the background of the public sector, however, it has scarcely been discussed and very little is known about its determinants and implications. Purpose of the article: This research investigates the role of organizational emotional engagement through relational contracts, senior management receptivity, and upward communication of employees in the public sector in stimulating work satisfaction and job efficiency. Methods: This research was based on data collected between April 1, 2020, and May 31, 2020, from 335 state employees from various governmental organizations in Ho Chi Minh City (HCMC), Vietnam. To evaluate the hypothesized model, partial least squares-structural equation modeling was used. Findings & value added: Our results illustrate that relational contracts have a powerful effect on emotional engagement. Positive relationships were confirmed between employee engagement and the voice of employees and between employee engagement and job performance. Moreover, the findings also support the role of senior management receptiveness in stimulating organizational emotional engagement. This study addresses questions about absence of academic studies on organizational emotional engagement in the public sector. The results highlight the important role of emotional engagement in stimulating job satisfaction and job performance through relational contracts, senior management receptiveness, and upward employee communication.
