Abstract

Purpose

The purpose of this paper is to identify and prioritize the key food safety practices among street food handlers that lead to microbial contamination in selected street foods of Hyderabad, India. These key food safety practices will help develop and design tailor-made training material for street food vendors in future.

Design/methodology/approach

It is a cross-sectional study conducted in south Indian city of Hyderabad. Stratified random sampling method was employed. A total of 463 samples of street foods were collected from five zones of Hyderabad. They included 163 salad toppings, 150 fresh fruit juices and 150 panipuri samples. Identification and enumeration of foodborne pathogens and indicator organisms (S. aureus, E. coli, Salmonella spp., Shigella spp., Bacillus cereus, Yersinia spp.) were performed as described by USFDA-BAM. Information on food safety knowledge and handling practices from street vendors were collected using a structured questionnaire. Associations between hygiene practices and bacterial pathogens were done using ANOVA. Risk estimation of food safety practices was assessed by calculating odds ratio.

Findings

Microbiological analysis indicated that a large number of carrot (98.1 percent) and onion (75.5 percent) samples were contaminated with E. coli. Peeled and cut fruits left uncovered have 13.4 times risk (OR: 2.40-74.8) of E. coli contamination compared to the covered ones. Panipuri samples picked from the vendors who did not have soap at the vending unit had significantly (p<0.001) higher contamination of fecal coliforms than those who had.

Originality/value

This study is the first of its kind in the study area.

Abstract

Purpose

The purpose of this paper is to review the nature and extent of foodborne diseases in India due to chemical and microbial agents.

Design/methodology/approach

The scientific investigations/reports on outbreak of foodborne diseases in India for the past 29 (1980‐2009) years due to adulteration, chemical, and microbiological contamination have been reviewed. Reported scientific information on foodborne pathogens detected and quantified in Indian foods has also been reviewed.

Findings

A total of 37 outbreaks involving 3,485 persons who have been affected due to food poisoning have been reported in India. Although the common forms of foodborne diseases are those due to bacterial contamination of foods, however, higher numbers of deaths have been observed due to chemical contaminants in foods.

Originality/value

A national foodborne disease surveillance system needs to be developed in India in order to enable effective detection, control and prevention of foodborne disease outbreaks.

Abstract

Purpose

The purpose of this paper is to contribute to the literature on secondary equity offerings (SEOs) by examining the impact of the Black Economic Empowerment (BEE) policy on secondary equity offering (SEO) pricing dynamics of South African Real Estate Investment Trusts (REITs).

Design/methodology/approach

With a sample of 152 SEOs of South African REITs from 2010 to 2020, ordinary least squares (OLS) models, fixed effect models, parametric and non-parametric tests were applied to test for the impact of BEE on the underpricing of SEOs.

Findings

Significant underpricing is discovered in highly compliant (BEE) REITs; in other words, SEOs pricing of BEE compliant REITs are more underpriced compared to non-compliant BEE REITs. With this, BEE compliant REITs and more so, highly compliant BEE REITs in particular leave more money on the table.

Practical implications

The government is therefore aware of the impact policy interventions play when REITs raise financing through SEOS. With these, highly compliant BEE REITs will need to be more strategic when making BEE compliance decisions as this is shown in our study to impact the underpricing of SEOs.

Originality/value

This is the first study to investigate SEO underpricing for the BEE policy using the South African REITs context.

Abstract

Purpose

This study aims to investigate the micropolar fluid flow through a moving flat plate containing CoFe2O4-TiO2 hybrid nanoparticles with the substantial influence of thermophoresis particle deposition and viscous dissipation.

Design/methodology/approach

The partial differential equations are converted to the similarity equations of a particular form through the similarity variables. Numerical outcomes are computed by applying the built-in program bvp4c in MATLAB. The process of flow, heat and mass transfers phenomena are examined for several physical aspects such as the hybrid nanoparticles, micropolar parameter, the thermophoresis particle deposition and the viscous dissipation.

Findings

The friction factor, heat and mass transfer rates are higher with an increment of 1.4%, 2.2% and 1.4%, respectively, in the presence of the hybrid nanoparticles (with 2% volume fraction). However, they are declined because of the rise of the micropolar parameter. The imposition of viscous dissipation reduces the heat transfer rate, significantly. Meanwhile, thermophoresis particle deposition boosts the mass transfer. Multiple solutions are developed for a certain range of physical parameters. Lastly, the first solution is shown to be stable and reliable physically.

Originality/value

As far as the authors have concerned, no work on thermophoresis particle deposition of hybrid nanoparticles on micropolar flow through a moving flat plate with viscous dissipation effect has been reported in the literature. Most importantly, this current study reported the stability analysis of the non-unique solutions and, therefore, fills the gap of the study and contributes to new outcomes in this particular problem.

The purpose of this study is to examine the influence of earnings management during initial public offerings on the listing day returns.

Abstract

Purpose

The purpose of this study is to examine the influence of earnings management during initial public offerings on the listing day returns.

Design/methodology/approach

The study collected data for 511 Indian IPOs that came between April 2003 and March 2019 for calculating earnings management. On the basis of the Cross Sectional Modified Jones Model 1995, the paper presents three proxies of earnings management as discretionary accruals (DA), discretionary current accruals (DCA) and discretionary long-term accruals (DLA). The study further used correlation and multiple regression analysis to assess the impact of earnings management on listing day returns.

Findings

The findings show that earnings management and listing day returns vary through issue-year and industry-type. Apart from it, the study reveals a greater contribution of short-term accruals in earnings management on the basis of higher DCA values. It also discloses that the aggregate level of earnings management (DA) influences listing returns, whereas DCA and DLA separately have no impact on the listing day returns of the Indian IPOs.

Research limitations/implications

The findings are useful to potential investors and analysts to observe, assess and understand the quality of financial reports that are based on fallacious disclosure of accounting figures. The study also reflects the efficacy of Indian regulatory norms for IPOs in constraining earnings management and underpricing, thus providing meaningful insight to the policy makers and the regulators.

Originality/value

This study is distinguished by its focus on determining the influence of earnings management on listing day returns in Indian IPOs by using three earnings management proxies.

Abstract

Purpose

The academic research into underpricing of initial public offerings (IPOs) offers many explanations, i.e. signalling, financial and market hypothesis. However, another set of information, namely, “Qualitative Factors” (along with financial and others), are largely reported by the issuing firms in the prospectus. However, to the best of the authors’ knowledge no such systematic study has been carried out on how firms’ qualitative factors impact the IPO valuation. This paper aims to addresses this gap.

Design/methodology/approach

Using a sample of 82 IPOs issued from 2014 to 2020, we investigate the issuing firm’s pattern of reporting qualitative factors. These qualitative factors are subjected to factor analysis. The authors classify all reported factors across firms into a few categories using principal component analysis. The authors also investigate the impact of these factors on IPO underpricing using OLS regression.

Findings

The authors find that the qualitative information relating to market leadership, established brand image and modern scalable information technology infrastructure significantly influences underpricing. The authors also document that market leadership and brand image are the influential reported quality factors that reduce underpricing. Moreover, location advantage, good customer relationship, established relationship with a client, track record of growth and profitability, experienced promoter and management team failed to influence underpricing.

Originality/value

The outcome of this piece of research offers additional signalling as an attestation of quality for the issue. The authors further argue that the amount of qualitative information disclosed by the managers in the prospectus to support the pricing should not be ignored.

Abstract

Purpose

The authors assessed the certification of street food retailers in Ghana in terms of awareness, training, willingness to be certified, determinants, agreement with certification requirements and impacts on performance.

Design/methodology/approach

Primary data was sourced from 200 street food retailers. Descriptive statistics, Likert scale, mean comparison test, heteroskedastic probit, inverse-probability-weighted regression adjustment (IPWRA), inverse probability weights (IPW) and augmented inverse-probability weighting (AIPW) were applied.

Findings

Most uncertified retailers were willing to be certified. Awareness about certification was high. Most of the certified retailers had been trained on certification, while most uncertified retailers had not been trained. Being a female, being educated, being a migrant vendor, possessing experience in retailing, training in certification, trust in the local certification process, the amount spent in preparing food and the number of customers are crucial variables that increase the probability of being certified among street food vendors. Street food retailers agreed to all the requirements for certification. Certification boosts the performance of street food retailers in terms of the number of customers and contracts received. Training on certification is recommended for street food retailers.

Research limitations/implications

The limitation of this study is mainly due to the type of food retailers selected. Street food vending in Ghana is done among those who cook food for selling, those who sell processed products such as drinks and those who sell vegetables and other uncooked agriproducts. Meanwhile, the authors selected unorganised retailers who primarily cook local and regional dishes for sale in this study. Thus, the study did not include organised food retailers such as restaurants. Therefore, generalising the study results for street food vendors should be made with caution.

Originality/value

Several studies have been conducted on street food retailing across the globe on knowledge of food-safety practices, risk practices, bacterial contamination of street retailing food, toxicological hazards of street foods and compliance with technical and hygienic requirements by street food retailers, among others. However, empirical studies on the certification/licensing of street food retailers and its impact have been given little attention. As a result, this study investigates the certification of street food retailers and its impacts on retailers' performance in Ghana.

Abstract

Purpose

This study aims to investigate the effect of externally applied magnetic force and heat transfer with a heat source/sink on the Couette flow with viscous dissipation in a horizontal rotating channel. The magnetic force is added to the governing equations. The effects of fluid flow parameters are observed under the applied magnetic force. In this system, the magnetic force is applied perpendicular to the plane of the fluid flow. In recent years, the magnetic field has renewed interest in aerospace technology. The physical and theoretical approach in the multidisciplinary field of magneto fluid dynamics (MFD) is applied in the field of aerospace vehicle design.

Design/methodology/approach

Authors use the perturbation method to solve and find the approximate solutions of differential equations. First, convert the partial differential equation to ordinary differential equation and calculate the approximate solutions in two cases. The first solution got by assuming heat generating in the fluid and the second one got when heat absorbing. After applying the external magnetic force, the effects of various fluid parameters velocity, temperature, skin friction coefficient and Nusselt number are found and discussed using tables and graphs.

Findings

It is found that the velocity of the fluid has decreased tendency when the rotation of the fluid and magnetic force on the fluid increases. The temperature of the fluid, Prandtl value and Eckert number increased when the heat source generated heat. When heat absorbs the heat, sink parameter increases and the temperature of the fluid decreases. Also, while heat absorbs, the temperature increases when the Prandtl value and Eckert number increase.

Originality/value

The skin friction coefficient on the surface increases, when the rotation parameter and the magnetic force parameter of the fluid increase. In the case of heat generating, the Nusselt number increased, while the Eckert number and Prandtl numbers increased. Also, the Nusselt number has larger values when the heat source parameter has near the constant temperature, and it has smaller values when the temperature varies. In the case of heat-absorbing, the Nusselt number decreased when the Eckert and Prandtl numbers increased. Also, the Nusselt number varies up and down while the heat absorbing parameter increases.

Abstract

Purpose

This cross-sectional study aimed to evaluate the compliance of hygienic and technical standards of street food vendors in Slovenia with the requirements of the general hygienic food principals set in the Codex Alimentarius and Regulation (EC) No. 852/2004 on the hygiene of foodstuffs.

Design/methodology/approach

Food vendors were observed directly and discretely using a semi-structured observation sheet that allowed fast evaluation. The employee's behaviour was not affected during the observations because they were not aware of being observed. Each observation lasted approximately 30 min. Food vendors were divided into groups according to their location, type of facility, number of employees and type of food sold.

Findings

Depending on the type of street vendor, more inconsistencies were found amongst food stands compared to food trucks and kiosks. Most food trucks and kiosks scored very high in both personal and hygienic-technical standards. Some of the major inconsistencies were lack of suitably located washbasins, improper hand-washing technique, improper waste management, working surfaces that were inadequately separated from consumers, and inconsistent maintenance of the cold chain. Food handlers have been confirmed as a critical risk factor.

Research limitations/implications

Despite methodology validation, the data was collected by a single observer, limiting the ability to obtain a more reliable estimate of the observations. The sample was disproportionate according to the type of street food facilities.

Practical implications

The results provide a basis for (1) national professional guidelines of good hygiene practices for food business operators, which should cover street food vendors more extensively in future updates, and (2) the development of food safety training programmes tailored for street vendors.

Originality/value

The study provides valuable insights into current hygienic-technical conditions of the street food vending sector.

Abstract

Purpose

The purpose of this study is to understand the different types of risks affecting the demand for the automotive sector in India. The study is further trying to illustrate an approach for analyzing the relative intensities of these risks in the present uncertain business environment.

Design/methodology/approach

Risk on the overall demand is assessed by a combined Bayesian – multi-criteria decision-making approach. Data related to the different factors, affecting their product demand is collected from major automobile firms. Then, weights for these factors are evaluated by applying the analytic hierarchy process approach. Further, these weights are used in the Bayesian analysis network to evaluate the risk intensity for different subgroups, namely, political, economic, social, technological and environmental.

Findings

From the literature and experts’ opinion, total 16 risk factors have been finalized and these are further grouped into 5 categories i.e. political, economic, social, technological and environmental. It is observed that the demand for organizations functioning in the automotive sector is more vulnerable to economic risk as compared to other risks considered in the study.

Practical implications

Managers and decision makers of associated organizations can use the proposed framework to assess the demand risks so as to pre-evaluate their demand corresponding to future changes. Factors can be added or removed and importance could be assigned to different risk factors according to the prevailing business environment for an organization or sector. This will also help the organizations to conduct a more effective risk management in an uncertain business environment.

Originality/value

The study will help in better understanding of the various demand risks prevalent in the Indian auto sector. The methodology used, provides a novel approach for assessing the macroeconomic demand risks and can be used by the firms working in the automotive sector. The proposed methodology could be used for assessing supply chain risk or any other business initiative risk. The suggested approach will help managers in devising flexible management techniques so as to mitigate the risk.
