Abstract

Purpose

β-Carotene is the most appropriate and significant precursor of vitamin A. Synthetic carotene supplements have been known to pose a threat to human health, making natural sources such as the indefensible choice for the production and extraction of carotene.

Design/methodology/approach

This study considers Blakeslea trispora, a filamentous fungus, as a source of production of carotenoids by fermentation and wet and dry mycelium were used to analyse and obtain better extraction results.

Findings

In this study, natural oils such as soy oil and cottonseed oil were incorporated into fermentation media to increase the production of carotene. For the optimization process, Plackett–Burman and one-factor-at-a-time (OVAT) models were identified as being of great value.

Originality/value

OVAT was carried out for corn starch because it plays a major role in the production of carotene and the corn starch at 30 g/L concentration has shown the maximum activity of 3.48 mg/gm. After optimizing process variables, submerged fermentation was eventually carried out under highly controlled media conditions. The resulting product was quantified using UV spectroscopy and extraction of carotene has been observed in the presence of various solvents. Among a range of solvents used, the methylene Di chloride produced-carotene at 86% recovery at a significantly lower temperature of 35°C.

Abstract

Purpose

Employees' well-being has emerged as a critical issue in the software industry. Therefore, our study examines the detrimental effect of exploitative leadership on subjective well-being directly and through self-efficacy. We also investigate the buffering effect of resilience on this relationship using the conversation of resources (COR).

Design/methodology/approach

Data were collected from 585 software industry professionals via two-way self-administered questionnaires. The proposed hypotheses were tested using Process Model 5.

Findings

Our study confirms the negative effect of exploitative leadership on subjective well-being, both directly and indirectly via self-efficacy. Furthermore, the findings indicate that resilience reduces the negative effect of exploitative leadership on subjective well-being.

Research limitations/implications

Our study contributes to the existing literature on exploitative leadership by demonstrating its detrimental effects on employee’s subjective well-being. It also provides a more nuanced understanding of the unexplored relationship between exploitative leadership and subjective well-being by explaining the mediating role of self-efficacy and the moderating role of resilience.

Practical implications

Policymakers and human resource practitioners may design training and development programs to promote morality and ethical behaviors. This will enhance employees' subjective well-being, aligning with SDG 3’s goal of ensuring healthy lives and promoting well-being for all.

Originality/value

Our study provides a novel perspective by expanding the nomological network of exploitative leadership to include lower self-efficacy and subjective well-being. It also extends our understating of how resilient employees sustain their well-being under exploitative leadership.

Abstract

Purpose

Recent literature in environmental management suggests that fostering employees’ innovative behaviour in green service is vital for enhancing the environmental sustainability of hospitality organizations. Despite this, few efforts have been made to understand how green entrepreneurial leadership (GEL) relates to green service innovative behaviour (GSIB). This study aims to examine whether GEL can promote GSIB among hospitality employees through the serial mediation of green learning orientation (GLO) and green knowledge acquisition (GKA) using the conservation of resources theory. The authors expect environmental dynamism to strengthen the relationship between GEL and employees’ GSIB, leveraging the resource-based view theory.

Design/methodology/approach

This study collected data through a multi-wave survey (four waves, two weeks apart) from 341 employees working in three-to-five-star hotels in Pakistan’s major cities. The authors used partial least squares structural equation modelling to evaluate the hypotheses proposed in the theoretical model.

Findings

The study revealed a significant relationship between GEL and employee GSIB, mediated by GLO and GKA. In addition, environmental dynamism strengthened the relationship of GEL with employee GSIB.

Originality/value

The research advances the literature on GEL in the hospitality sector by providing insights into the mediating and moderating processes that translate GEL into GSIB among hospitality employees. Moreover, the research provides important implications for hotels investing in green initiatives and looking for ways to foster employees’ GSIB.

Abstract

Purpose

This study aims to investigate two important research questions. First, this research examines the impact of real earnings management on investment inefficiency of the non-financial listed firms in Pakistan. Second, this research further explores the moderating role of short-term debt on the nexus between real earnings management and investment inefficiency. This study attempts to highlight an important research problem i.e. the jinx of real earnings management from the context of an emerging economy.

Design/methodology/approach

This study employs the data from non-financial listed firms in Pakistan over the period from 2008 to 2018. The study uses panel data methodologies with firm and year fixed-effects to examine the proposed hypotheses. The results are robust to the use of sensitivity analysis, different estimation techniques and endogeneity issues (using two-stage least squares (2SLS) and generalized method of moments (GMM) techniques).

Findings

The results of the research are twofold. First, consistent with the theoretical arguments, the findings reveal that real earnings management increases investment inefficiency and results in over-investments by the firms. Second, short-term debt attenuates the relationship between real earnings management and investment inefficiency. It implies that a higher level of short-term debt weakens the adverse effects of real earnings management on the investment efficiency of the firm.

Originality/value

This study offers original findings on the issues pertaining to the quality of accounting and financial reporting in an emerging economy like Pakistan, where the implementation of regulations is weak in the corporate world and management frequently exploits shareholders' wealth for the short-term benefits.
