Abstract

Purpose

A comprehensive literature review was conducted to identify the lean principles and the challenges of building refurbishment. To have an in-depth investigation of the application of lean principles to address the challenges of refurbishment projects, ten expert interviews following a qualitative research approach were utilised in this research. Data were analysed using manual content analysis to derive the framework.

Design/methodology/approach

The refurbishment of buildings has attracted the attention of the present construction industry. However, uncertain project characteristics, information deficiency, limited space for construction activities and less stakeholder involvement make it complex. Since the lean concept effectively deals with complex and uncertain projects, this study focusses to investigate the application of lean principles to overcome the challenges of refurbishment projects in Sri Lanka by developing a framework.

Findings

It was found that the five main lean principles of customer value, value stream, value flow, pull and perfection are appropriate for building refurbishment projects in Sri Lanka. Precise identification of clients and end-users, value adding and non-value adding activities, interruptions and stakeholder communication chains, setting scope, examining the possible technologies and taking measures to deliver the exact product to ensure the successful application of lean principles for refurbishment projects. Further, 27 benefits of five lean principles were identified which can be used to address the 13 identified challenges of building refurbishment of projects. Finally, a framework has developed portraying the application of lean principles in building refurbishment.

Practical implications

The framework developed is beneficial for the building refurbishment project team to address the barriers of refurbishment projects by applying lean principles.

Originality/value

This framework can be used as a guideline for the implementation of building refurbishment projects by addressing their challenges with lean principles.

Abstract

Purpose

This study examines the relationship between the emphasis on organic food in Afyonkarahisar's cuisine and the growing demand for healthier and sustainable options. This study aimed to understand the factors influencing the intention to consume organic foods.

Design/methodology/approach

This study uses a quantitative research method. It uses scales adapted from previous research to assess the health and safety of organic food's functional, hedonic, and social values. Data were collected using the purposive sampling method, and a sample size of 410 individuals was analyzed using the PLS-SEM method. Measurement and structural models were evaluated to assess validity, reliability, and model fit.

Findings

The results indicate that implementing health and safety practices significantly and positively affects perceptions of organic food's functional, hedonic, altruistic, and social values. Additionally, consumers' attitudes toward organic food are greatly influenced by their perceptions of functional and social value, whereas hedonic and altruistic values do not have a significant positive effect.

Practical implications

The results of this study have a beneficial impact on food industry practitioners and policymakers. Emphasizing health and safety practices in producing and promoting organic foods can improve consumer perceptions and attitudes toward organic products. Understanding the importance of practical benefits and social issues can help companies respond effectively to consumer preferences and market organic foods.

Originality/value

This study contributes significantly to the existing literature by investigating the relationship between organic food emphasis and consumer perceptions in the unique context of Afyonkarahisar, a city renowned for its gastronomy. While focusing on Afyonkarahisar provides valuable insights into the specific values that influence consumers' attitudes toward organic food, it is essential to highlight that this research extends beyond the local context to offer broader implications and significance.

Abstract

Purpose

To generate the measurement instrument seven steps were implemented. A total of 819 questionnaires were collected in Yunnan Province, China, where it has long tradition of eating insects.

Design/methodology/approach

This study aims to explore the influences of the multidimensional benefits of consuming insect-based food on its consequences. Food neophilia and hedonic motivation are used as moderating variables.

Findings

Health, nutritional value, taste and cultural domains effectively explained consumers’ attitudes toward insect-based food, food consumption value, satisfaction, subjective well-being, loyalty to the restaurant and community attachment. Food neophilia and hedonic motivation partially moderated the relationships between the proposed constructs.

Research limitations/implications

This study provides a conceptual model for exploring insect-based food consumption experiences and offers a useful guideline for developing and designing marketing strategies for stakeholders in the food and restaurant industry.

Originality/value

This is one of the few studies examining the benefits of consuming insect-based food from the perspective of consumers.

Abstract

Purpose

Petroleum hydrocarbons are naturally occurring flammable fossil fuels used as conventional energy sources. It has carcinogenic, mutagenic properties and is considered a hazardous pollutant. Soil contaminated with petroleum hydrocarbons adversely affects the properties of soil. This paper aim to remove pollutants from the environment is an urgent need of the hour to maintain the proper functioning of soil ecosystems.

Design/methodology/approach

The ability of micro-organisms to degrade petroleum hydrocarbons makes it possible to use these microorganisms to clean the environment from petroleum pollution. For preparing this review, research papers and review articles related to petroleum hydrocarbons degradation by micro-organisms were collected from journals and various search engines.

Findings

Various physical and chemical methods are used for remediation of petroleum hydrocarbons contaminants. However, these methods have several disadvantages. This paper will discuss a novel understanding of petroleum hydrocarbons degradation and how micro-organisms help in petroleum-contaminated soil restoration. Bioremediation is recognized as the most environment-friendly technique for remediation. The research studies demonstrated that bacterial consortium have high biodegradation rate of petroleum hydrocarbons ranging from 83% to 89%.

Social implications

Proper management of petroleum hydrocarbons pollutants from the environment is necessary because of their toxicity effects on human and environmental health.

Originality/value

This paper discussed novel mechanisms adopted by bacteria for biodegradation of petroleum hydrocarbons, aerobic and anaerobic biodegradation pathways, genes and enzymes involved in petroleum hydrocarbons biodegradation.

Abstract

Purpose

The migration of physicians is a global interest, causing imbalances between developed and developing countries. Romania is one of Europe's major providers of physicians, not because there is a surplus, but because physicians are drawn to places with better living and working conditions. Medicine in Romania is increasingly highly advanced, and Romanian physicians are well appreciated all over the world. Despite being one of the countries with the most medical graduates in the world, Romania is suffering a doctor exodus. After joining the EU, the problem of physician migration became widespread, resulting in a deficient and inefficient healthcare system. Therefore, the purpose of this study is to estimate the losses registered by Romania because of physicians' decision to migrate.

Design/methodology/approach

These losses were calculated in two ways: utilizing the statistical life value and the amount of money invested in training a medical graduate.

Findings

According to the findings, the losses in 2018 were 104.16 million euros, approximately 0.12% of GDP.

Originality/value

The originality of this paper consists in data, being provided by the College of Physicians from Romania and the method used, this study being the only one that estimates the cost of Romanian physicians' migration. The paper adds to existing knowledge an empirical results regarding quantifying the value reflecting the departure of physicians, using value of statistical life and the amount of money invested in preparing a medical graduate.

Corporate site visits increase labor investment efficiency.

Abstract

Purpose

Corporate site visits increase labor investment efficiency.

Design/methodology/approach

Our empirical model for the baseline analysis follows those of Jung et al. (2014) and Ghaly et al. (2020).

Findings

We show that corporate site visits are associated with significantly higher labor investment efficiency; more specifically, site visits reduce both over-hiring and under-hiring of employees. The effect of site visits on labor investment efficiency is more pronounced for firms with higher labor adjustment costs, greater financial constraints, weaker corporate governance and lower financial reporting quality. We also find that site visits mitigate labor cost stickiness.

Originality/value

First, while the literature has suggested how the presence of institutional investors and analysts may affect labor investment decisions, we focus on institutional investors and analysts’ activities and interactions with firm executives. We provide direct evidence that institutional investors and analysts may use corporate site visits to improve labor investment efficiency. Second, our study adds to a line of recent studies on how corporate site visits reduce information asymmetry and agency conflicts. We show that corporate site visits allow institutional investors and analysts to influence labor investment efficiency. We also provide new evidence that corporate site visits reduce labor cost stickiness.

Abstract

Purpose

Employees play a vital role in the success of a corporation. While boards of directors are created to protect shareholders’ interests, it is unclear if these directors also ensure employee welfare. In this vein, our paper examines the relationship between board leadership structure and employee well-being.

Design/methodology/approach

The authors employ several analysis techniques, including univariate analysis, ordinary least squares (OLS) regressions, two-stage least squares (2SLS) regressions, propensity score matching methodology, the Heckman Selection model and difference-in-differences analysis. The sample comprises USA public firms for the period 1998–2018.

Findings

Our findings indicate that having an independent chairperson can significantly benefit the welfare of employees, especially for firms with overly powerful chief executive officers (CEOs) and during times of financial distress.

Originality/value

Independent leadership structure is one of the crucial board characteristics that have not been examined to explain employee welfare at firms. We find that an independent chairperson can mitigate the negative effect of overly powerful CEOs on employee benefits. Importantly, independent chairpersons are beneficial for employees in difficult times and when CEOs are busy with daily activities.
