It is possible with classical path planning algorithms to plan a path in a static environment if the instant position of the vehicle is known and the target and obstacle positions are constant. In a dynamic case, these methods used for the static environment are insufficient. The purpose of this study is to find a new method that can provide a solution to the four-rotor unmanned aerial vehicle (UAV) path planning problem in static and dynamic environments.

As a solution to the problem within the scope of this study, there is a new hybrid method in which the global A* algorithm and local the VFH+ algorithm are combined.

The performance of the designed algorithm was tested in different environments using the Gazebo model of a real quadrotor and the robot operating system (ROS), which is the widely used platform for robotic applications. Navigation stacks developed for mobile robots on the ROS platform were also used for the UAV, and performance benchmarks were carried out. From the proposed hybrid algorithm, remarkable results were obtained in terms of both planning and implementation time compared to ROS navigation stacks.

This study proposes a new hybrid approach to the path planning problem for UAVs operating in both static and dynamic environments.

Central to the entire discipline of construction safety management is the concept of construction accidents. Although distinctive progress has been made in safety management applications over the last decades, construction industry still accounts for a considerable percentage of all workplace fatalities across the world. This study aims to predict occupational accident outcomes based on national data using machine learning (ML) methods coupled with several resampling strategies.

Occupational accident dataset recorded in Turkey was collected. To deal with the class imbalance issue between the number of nonfatal and fatal accidents, the dataset was pre-processed with random under-sampling (RUS), random over-sampling (ROS) and synthetic minority over-sampling technique (SMOTE). In addition, random forest (RF), Naïve Bayes (NB), K-Nearest neighbor (KNN) and artificial neural networks (ANNs) were employed as ML methods to predict accident outcomes.

The results highlighted that the RF outperformed other methods when the dataset was preprocessed with RUS. The permutation importance results obtained through the RF exhibited that the number of past accidents in the company, worker's age, material used, number of workers in the company, accident year, and time of the accident were the most significant attributes.

The proposed framework can be used in construction sites on a monthly-basis to detect workers who have a high probability to experience fatal accidents, which can be a valuable decision-making input for safety professionals to reduce the number of fatal accidents.

Practitioners and occupational health and safety (OHS) departments of construction firms can focus on the most important attributes identified by analysis results to enhance the workers' quality of life and well-being.

The literature on accident outcome predictions is limited in terms of dealing with imbalanced dataset through integrated resampling techniques and ML methods in the construction safety domain. A novel utilization plan was proposed and enhanced by the analysis results.

This paper aims to analyse the effect of mandatory corporate social responsibility expenditure (CSRE) on the performance of food and agribusiness firms in India.

This study is based on the firm-level data collected from the Prowess database of the Centre for Monitoring Indian Economy in the year 2019. The data on key characteristics, business performance and CSRE has been compiled from 362 food and agribusiness firms. The descriptive statistics, t-test for equality of means and Spearman correlation analysis have been undertaken to understand the relationship between mandatory CSRE and firm performance across food and agribusiness sectors.

Out of 362 food and agribusiness firms, 52.2% have reported expenditure in the implementation of social initiatives under their corporate social responsibility. The results show a significant difference in the firm’s characteristics vis-à-vis with and without CSRE. Further, the findings highlight a positive and significant correlation and causal impact of corporate social responsibility (CSR) on return on sales, return on assets and profit after tax.

The study provides insights for implementing strategic CSR in food and agribusiness firms and gives an adequate justification for incurring CSRE.

This paper increases the understanding of CSR in the food and agribusiness sector. Besides, provisioning mandatory CSR seems to be a beneficial proposition for enhancing a firm’s performance.

Acrylamide (AA) is predominantly used as a synthetic substance within various industries. However, AA is also recognized as a carcinogen. Zinc oxide nanoparticles (ZnO-NPs) are becoming increasingly attractive as medical agents. However, to the knowledge, the effects of ZnO-NPs on preventing cytotoxicity with AA have not been reported. Therefore, this study aims to determine the protective effects of ZnO-NPs against the cytotoxicity caused by AA.

MTT assay was used to determine the cytotoxicity. Reactive oxygen species (ROS) formation, carbonyl protein, malondialdehyde (MDA) and glutathione (GSH) were measured and analyzed statistically.

The findings observed that the presence of 200 µM AA led to a substantial reduction in cell viability (p < 0.001). However, ZnO-NPs restored cell viability at 50 and 100 µM concentrations (p = 0.0121 and p = 0.0011, respectively). The levels of ROS were significantly reduced (p = 0.001 and p = < 0.001) to 518 ± 47.57 and 364 ± 47.79, respectively, compared to the AA group. The levels of GSH were significantly increased (p = 0.004 and p = 0.002) to 16.9 ± 1.3 and 17.6 ± 0.5, respectively, compared to the AA group. The levels of MDA were significantly decreased (p = 0.005, p < 0.001 and p < 0.001) when compared to the AA group, as were the levels of carbonyl protein (p = 0.009 and p < 0.002) in comparison to the AA group.

In summary, the outcomes of this research indicate that ZnO-NPs played a role in inhibiting AA-induced oxidative stress and cytotoxicity.

This study aims to investigate the impact of stakeholders’ nonfinancial resources (NFRs) on companies’ profitability, filling a significant gap in the literature regarding the role of NFRs in value creation.

Data from 76 organizations from 2017 to 2019 were collected and analyzed. Four primary NFRs and their key value drivers were identified, representing core elements that support different dimensions of a company’s performance. Statistical tests examined the relationship between stakeholders’ NFRs and financial performance measures.

When analyzed collectively and individually, the results reveal a significant positive influence of stakeholders’ NFRs on a firm’s profitability. Higher importance assigned to NFRs correlates with a higher return on sales.

This study contributes to the literature by empirically bridging the gap between stakeholder theory and the resource-based view, addressing the intersection of these perspectives. It also provides novel insights into how stakeholders’ NFRs impact profitability, offering valuable implications for research and managerial practice. It suggests that managers should integrate nonfinancial measures of NFRs within their performance measurement system to manage better and sustain companies’ value-creation process.

The purpose of this paper is to meet Mary Kay Morrison, an active member and past president of the Association for Applied and Therapeutic Humor (AATH).

This case study is presented in two sections: an autobiography of Mary Kay Morrison, followed by a ten-question interview.

Mary Kay recommends exploration of the benefits of humor and laughter for mental health professionals. In recognition of the need for clarifying terminology, she coined the terms Humergy, which is joyful, optimistic, healthy energy and Humordoomer, which denotes a person who zaps that energy from us. Her work includes exploring the five stages of Humor Development as a significant factor in understanding cognitive development.

This is a personal narrative, albeit from an educator who has been active in the field of applied and therapeutic humor for over 30 years.

Humor and laughter research is recommended to explore their use in optimizing mental health. Mary Kay endorses expanding pioneering work in therapeutic humor as a treatment for anxiety and depression. She shares recommendations for humor practice in both prevention of mental health challenges and as a viable treatment for anxiety and depression.

Three humor benefits with particular social applications are highlighted. Humor facilitates communication, creates an optimal learning environment and supports change.

To the best of the authors’ knowledge, this is the first case study about Mary Kay Morrison, Past President of the AATH and founder of the AATH Certified Humor Professional program.

The purpose of this paper is to meet Dr Madan Kataria, the founder and creator of Laughter Yoga.

This case study is presented in two sections: a transcribed autobiography of Madan Kataria, followed by a ten-question interview with him.

The popularity of Laughter Yoga (LY) has spread from a handful of people since 1995 to a global movement with tens of thousands of people who commune in person and online, laughing for the health of it.

This is a personal narrative, albeit from someone who has been at the forefront of using intentional laughter for well-being for 30 years.

LY promotes an array of physical, psychological and emotional health outcomes that does not rely on humour or jokes to stimulate laughter. It is a beneficial resource suited for use in vulnerable population groups, including people experiencing depression or anxiety.

The LY methodology is suited to people of all ages and abilities, enhancing mental health, decreasing stress levels and growing social connections and community through the universal language of laughter.

To the best of the authors’ knowledge, this is the first case study and interview with Dr Kataria that delves into his personal background, outlining his motivation and experience behind founding LY internationally.

Many observers believe that industry experience of entrepreneurs drives successful new entrepreneurial firms. However, whenever it comes to disruptive digital ventures such as Financial Technologies (Fintechs), the picture may be different due to the cross-industry nature of digital firms. The purpose of this study is to disentangle the impacts of finance, banking and information technology (IT) experiences of founders on performance of European Fintechs around venture capital (VC) investment.

Based on a data set of 105 Fintechs from European countries, including UK, which are involved in 201 VC rounds between 2006 and 2019, the authors adopt a Bayesian quantile approach to link founders’ experience with two performance measures that identify market success (return on sales) and investment outcome (return on equity).

The findings indicate that finance and IT-specific experiences seem to matter more often than banking experience and that the extent of their impact depends on level and metric of performance. More specifically, Fintechs in Europe and UK are more able to achieve market success with both finance and IT experiences of their founders, but that does not necessarily transform into higher returns for investors.

This study provides new evidence that not all aspects of industry experience matter for digital ventures, as they must fit to a certain firm, cycle and industry. For Fintech, as the name says, finance and IT experiences matter.

The purpose of this study is to examine the impact of corporate social responsibility (CSR) expenditure and business responsibility report (BRR) on a firm’s financial performance. Additionally, the study explores whether CSR expenditure and firm performance are related linearly or otherwise. The study also assesses the influence of mandating CSR expenditure on a firm’s performance.

The study is set in India and uses a nine-year data set from 165 companies listed on the Bombay Stock Exchange. Data compilation and analysis are done by using content analysis and panel data regressions.

The main findings of the study are that the effect of CSR expenditure on firm performance in India is non-linear and can be characterized as parabolic for investigated firms. While some performance indicators suggest a U-shaped relationship, others show an inverted U-type pattern, making a definitive conclusion elusive in either direction. BRR scores themselves have a positive impact on firm performance. Mandatory CSR expenditure affects the financial performance negatively, but the market performance improves in general.

The study provides new insights on the relationship between CSR expenditure, BRR scores and firm performance from India, which is not only a notable emerging market but also has other gripping characteristics. It has a prolific history of philanthropy, and yet, it is the first country in the world to mandate CSR expenditure in recent times. The equation between reported economic progress and general quality of life remains intriguing, and yet the number of studies on the effects of CSR expenditure on firm performance are no match to the volume of ongoing and completed works in more developed markets. This study attempts to trim the gap and provide some useful insights for managers, policymakers and stakeholders, apart from prompting further research.
