Abstract
Purpose
The study aims to explore the mediating role of flow at work and moderating role of creative self-efficacy in the relationship between authentic leadership and innovative work behavior.
Design/methodology/approach
The study collected data from 315 employees working in the service sector through survey design. Data analysis was done through structural equation modeling.
Findings
The findings revealed that authentic leadership is related to flow at work and innovative work behavior. Flow at work was also found to be related to innovative work behavior. Flow at work was found to mediate the relationship between authentic leadership and innovative work behavior. The study also confirmed the moderating role of creative self-efficacy in the relationship between authentic leadership and innovative work behavior.
Originality/value
The study unearthed the previously unexplored mediating role of flow at work linking authentic leadership to innovative work behavior. Additionally, it is the first study that explicated how creative self-efficacy moderates the relationship between authentic leadership and innovative work behavior; the relationship between the two is stronger when creative self-efficacy is high.

Abstract
Purpose
The purpose of this study is to develop a molecular imprinting electrochemical sensor for the specific detection of the anticancer drug amsacrine. The sensor used a composite of bacterial cellulose (BC) and silver nanoparticles (AgNPs) as a platform for the immobilization of a molecularly imprinted polymer (MIP) film. The main objective was to enhance the electrochemical properties of the sensor and achieve a high level of selectivity and sensitivity toward amsacrine molecules in complex biological samples.
Design/methodology/approach
The composite of BC-AgNPs was synthesized and characterized using FTIR, XRD and SEM techniques. The MIP film was molecularly imprinted to selectively bind amsacrine molecules. Electrochemical characterization, including cyclic voltammetry and electrochemical impedance spectroscopy, was performed to evaluate the modified electrode’s conductivity and electron transfer compared to the bare glassy carbon electrode (GCE). Differential pulse voltammetry was used for quantitative detection of amsacrine in the concentration range of 30–110 µM.
Findings
The developed molecular imprinting electrochemical sensor demonstrated significant improvements in conductivity and electron transfer compared to the bare GCE. The sensor exhibited a linear response to amsacrine concentrations between 30 and 110 µM, with a low limit of detection of 1.51 µM. The electrochemical response of the sensor showed remarkable changes before and after amsacrine binding, indicating the successful imprinting of amsacrine in the MIP film. The sensor displayed excellent selectivity for amsacrine in the presence of interfering substances, and it exhibited good stability and reproducibility.
Originality/value
This study presents a novel molecular imprinting electrochemical sensor design using a composite of BC and AgNPs as a platform for MIP film immobilization. The incorporation of BC-AgNPs improved the sensor’s electrochemical properties, leading to enhanced sensitivity and selectivity for amsacrine detection. The successful imprinting of amsacrine in the MIP film contributes to the sensor's specificity. The sensor's ability to detect amsacrine in a concentration range relevant to anticancer therapy and its excellent performance in complex sample matrices add significant value to the field of electrochemical sensing for pharmaceutical analysis.

Abstract
Purpose
This study aims to investigate how social entrepreneurial role models influence social entrepreneurial self-efficacy, social entrepreneurial intent and social entrepreneurial action, with moral obligation as a moderator.
Design/methodology/approach
A cross-sectional survey of 261 pupils in the South African province of the Eastern Cape was used in the research study. Structural equation modeling was used to test hypotheses.
Findings
The research revealed that having social entrepreneurial role models has a positive impact on both social entrepreneurial self-efficacy and social entrepreneurial intent. In addition, a connection was found between social entrepreneurial intent and entrepreneurial action. The influence of moral obligation was found to be a positive and a significant moderator. Moreover, the association between social entrepreneurial role models and social entrepreneurial intent was mediated by social entrepreneurial self-efficacy.
Research limitations/implications
The findings are not generalizable to nonstudent samples because students constituted the sample for gathering data. Future study therefore requires considering nonstudents to generalize the outcomes. This research should be replicated in other South African provinces and other developing countries for comparative outcomes.
Practical implications
Since social entrepreneurial role models have been practically linked to social entrepreneurship intent and entrepreneurial efficacy, understanding the factors that influence student’s decision to start a social enterprise is critical in South Africa to develop targeted interventions aimed at encouraging young people to start new businesses. Policymakers, society and entrepreneurial education will all benefit from the findings.
Originality/value
This study contributes to bridging the knowledge gap as it investigates how social entrepreneurial role models influence social entrepreneurial self-efficacy, social entrepreneurial intent and social entrepreneurial action, with moral obligation as a moderator. Encouraging social entrepreneurship among South African youth would also help address societal issues. This is a pioneering study in the context of an emerging economy such as South Africa, where social entrepreneurship is so integral.

This study aims to undertake a review of how carbon trading contributes to a reduction in emission of greenhouse gases (CHGs).
Abstract
Purpose
This study aims to undertake a review of how carbon trading contributes to a reduction in emission of greenhouse gases (CHGs).
Design/methodology/approach
A narrative literature review approach was adopted to identify and synthesise existing literature using the Scopus and Web of Science databases. Articles were limited to the past 10 years to obtain the most current literature. The various ways in which carbon trading leads to reductions in emissions were identified and discussed.
Findings
The results showed that the main ways in which carbon trading contributes to reductions in emissions are through innovation in low-carbon technologies, restoration of ecosystems through offset money, development of renewable and clean energy and providing information on investment related to emissions.
Practical implications
The value of this study is to contribute to the built environment’s climate change mitigation agenda by identifying the role of carbon trading.
Originality/value
The output of this research identifies and contextualises the role carbon trading plays in the reduction of CHG emissions.

Abstract
Purpose
This paper aims to focus on analyzing the level of corruption of small- and medium-sized enterprises and their economic performance impact in Western Balkan countries. This study uses survey data from Enterprise Surveys (ES) from 2019, a shared project of the European Bank for Reconstruction and Development, the European Investment Bank and the World Bank Group. The selected countries are Albania, Bosnia and Herzegovina, North Macedonia, Kosovo, Montenegro and Serbia. The questions included in the data set contribute to understanding what firms experience in the private sector. Collected data are based on firms’ experiences and enterprises’ perceptions of the environment in which they operate.
Design/methodology/approach
This paper measures enterprise performance in terms of sales, employees and fixed assets growth. The vector of independent variables comprises enterprise characteristics such as enterprise age, size, ownership structure, legal status, access to formal banking services, gender ownership and other composed variables. Moreover, to capture the level of perceived corruption by firms, we will focus on the following ES questions: “Is it common to have to pay some irregular additional payment or gifts to get things done with regard to customs, taxes, licenses, regulations, services,” and the “corruption payment” is defined in the form of a dummy equal to one if the enterprise replies “frequently,” “usually” or “always.”
Findings
Preliminary empirical research results shed light on the level and effects of corruption on enterprises’ performance. However, the magnitude and statistical significance are different among the countries included in the sample.
Originality/value
Instead of firm-level characteristics, research on corruption frequently focuses on effects dependent on national and institutional characteristics. To better identify the kinds of businesses that are most at risk of corruption, we have selected to focus on differences among firm characteristics in this research. Understanding factors at the firm level is preferred from a policy perspective because these findings assist policymakers to make recommendations.
