“…A higher correlation between the criterion and the predictor indicates that the predictive validity is greater. According to Taherdoost (2016), the minimum recommended value for the valid items' loading is above 0.4, but Mohajan (2017) said that items with a loading between 3.0 and 0.6 are accepted as valid items. The decision about validity in this study refers to Mohajan (2017).…”

“…The most frequently used reliability test is Cronbach's alpha coefficient (Mohajan, 2017), (Taherdoost, 2016). Cronbach's alpha values above 0.70 are acceptable and satisfactory, above 0.80 are quite good, above 0.90 reflect exceptional consistency (Mohajan, 2017). This is almost in line with Taherdoost (2016).…”

Introduction: A brand’s popularity on social media affects its customers’ purchasing intention and purchasing decision. Background Problem: A review of the literature shows that a brand’s popularity on social media has a secure connection with its content and the time information about it is posted; allegedly the brand’s interactions are also influential. Indicators of its popularity include the number of likes, shares, comments, and views for it. Novelty: Previous brand popularity studies were limited to the features of likes, comments, and shares as a function of the content and time, and OLS was commonly used. However, this study adds the views feature and the function of the administrator’s comments to complete the gap. GLS is used as the method of analysis. Research Method: Data are collected through the observation of six top international food and beverage products’ categories on the Facebook fan page. The data were analyzed using the Seemingly Unrelated Regression (SUR), and the Mann-Whitney and Kruskal-Wallis methods. Findings: The study’s findings shows that video and the day to post have a significant influence and increase the number of likes, shares, comments, and views. A caption only shows significance to increase the number of likes and shares. The hour has a significant effect on comments and shares. The time of posting indicates that posting on weekdays and during busy periods is more effective for increasing the popularity of brands. The administrator’s comments significantly influence the increase in the number of comments and views, while two-way communication is more significant for increasing a brand’s popularity. Conclusion: These findings provide a deeper insight to help managers to improve their brand’s popularity on social media by exploring how brands manage their fan pages.

“…A. Hatch identifies five research paradigms: positivist, post-positivist, constructivist, critical/feminist, and poststructuralist; and poses ontological, epistemological, and methodological questions for each [Hatch, 2002]. In a review paper Haradhan Kumar Mohajan has discussed reliability and validity of a good research that increase transparency, and decrease opportunities to insert researcher bias in qualitative research [Mohajan, 2017].…”

Abstract. This literature review paper discusses the proper use of qualitative research methodology to discuss several research aspects for the improvement of the readers' skill. During the last few decades, the use of qualitative research has been increased in many institutions. It can be used to explore several areas of human behavior for the development of organizations. The purpose of this study is to provide inspirations to the new researchers for the development of their qualitative articles. The paper analyzes the design of qualitative research giving some methodological suggestions to make it explicable to the reader. In thispaper, an attempt has been taken to study the background of the qualitative research methodology in social sciences and some other related subjects, along with the importance, and main features of the study.

Peer review declarationThe publisher (AOSIS) endorses the South African 'National Scholarly Book Publishers Forum Best Practice for Peer Review of Scholarly Books'. The manuscript underwent an evaluation to compare the level of originality with other published works and was subjected to rigorous two-step peer review before publication, with the identities of the reviewers not revealed to the editor(s) or author(s). The reviewers were independent of the publisher, editor(s), and author(s). The publisher shared feedback on the similarity report and the reviewers' inputs with the manuscript's editor(s) or author(s) to improve the manuscript. Where the reviewers recommended revision and improvements, the editor(s) or author(s) responded adequately to such recommendations. The reviewers commented positively on the scholarly merits of the manuscript and recommended that the book be published.v Research justificationThis book focuses on the environmental ergonomics of restaurant kitchens and the challenges related hereto in a semi-tropical city, Durban, from a chef's perspective. It establishes the urgent need for commercial kitchens to be conducive to the wellbeing of kitchen workers, as heat illness is unreported in this industry. This research is relevant from occupational health and safety point of view. It evaluates the indoor environmental quality (IEQ) parameters such as heat, ventilation and humidity, noise and lighting in kitchens, and it is cognisant that with different cuisines, the kitchen loads are different. The goal of occupational safety is health intervention for worker comfort to enhance work performance. The book generates new knowledge regarding the factors affecting the body mass index of kitchen workers, prediction of heat and humidity near cooking stoves, discomfort near ovens, lighting in preparation areas and factors affecting reaction to stove noise. The book implements an exploratory design with multiple-case studies. The manuscript is structured into broad chapters on heat, ventilation and humidity, noise and lighting. Data analysis is an essential component of new knowledge, and a detailed description will promote certain research concepts among scholars to acquire research skills. The themes move from the hospitality industry in general and narrow down to commercial kitchens and specifically aim at students learning and training in culinary skills. The book accordingly scrutinises theory in respect of the relationship between individual differences and contextual components, and it factored these into controlled heat in a work environment and other IEQ parameters. This book advances existing physical conditions, as well as physiological and psychological influences of these parameters in commercial kitchens on worker relief-seeking behaviour adaptations. A ground-breaking new framework that optimises workstation comfort levels of kitchen workers is presented, hence offering insightful environmental contributions to improve commercial kitchen design and awareness among kitchen designers, erg...
