Purpose – Food poisoning attributable to the home generates a large disease burden, yet is an unregulated and largely unobserved domain. Investigating food safety awareness and routine practices is fraught with difficulties. The purpose of this paper is to develop and apply a new survey tool to elicit awareness of food hazards. Data generated by the approach are analysed to investigate the impact of oberservable heterogeneity on food safety awareness. Design/methodology/approach – The authors develop a novel Watch-and-Click survey tool to assess the level of awareness of a set of hazardous food safety behaviours in the domestic kitchen. Participants respond to video footage stimulus, in which food hazards occur, via mouse clicks/screen taps. This real-time response data is analysed via estimation of count and logit models to investigate how hazard identification patterns vary over observable characteristics. Findings – User feedback regarding the Watch-and-Click tool approach is extremely positive. Substantive results include significantly higher hazard awareness among the under 60s. People who thought they knew more than the average person did indeed score higher but people with food safety training/experience did not. Vegetarians were less likely to identify four of the five cross-contamination hazards they observed. Originality/value – A new and engaging survey tool to elicit hazard awareness with real-time scores and feedback is developed, with high levels of user engagement and stakeholder interest. The approach may be applied to elicit hazard awareness in a wide range of contexts including education, training and research.

Web Real-Time Communication (WebRTC) combines a set of standards and technologies to enable high-quality audio, video, and auxiliary data exchange in web browsers and mobile applications. It enables peer-to-peer multimedia sessions over IP networks without the need for additional plugins. The Opus codec, which is deployed as the default audio codec for speech and music streaming in WebRTC, supports a wide range of bitrates. This range of bitrates covers narrowband, wideband, and super-wideband up to fullband bandwidths. Users of IP-based telephony always demand high-quality audio. In addition to users’ expectation, their emotional state, content type, and many other psychological factors; network quality of service; and distortions introduced at the end terminals could determine their quality of experience. To measure the quality experienced by the end user for voice transmission service, the E-model standardized in the ITU-T Rec. G.107 (a narrowband version), ITU-T Rec. G.107.1 (a wideband version), and the most recent ITU-T Rec. G.107.2 extension for the super-wideband E-model can be used. In this work, we present a quality of experience model built on the E-model to measure the impact of coding and packet loss to assess the quality perceived by the end user in WebRTC speech applications. Based on the computed Mean Opinion Score, a real-time adaptive codec parameter switching mechanism is used to switch to the most optimum codec bitrate under the present network conditions. We present the evaluation results to show the effectiveness of the proposed approach when compared with the default codec configuration in WebRTC.

Purpose – This paper aims to outline the food safety roles and responsibilities within the industry that play an important role in the success of government initiatives, demonstrated using a new model of Food Safety Culture Excellence. It is the sixth article in a Worldwide Hospitality and Tourism Themes theme issue presenting a comprehensive government strategy for improving food safety management standards across the hospitality industry. Design/methodology/approach – A case study is used to demonstrate the impact of auditing the 16 dimensions of Food Safety Culture Excellence in practice. The business selected was the first in Abu Dhabi to achieve regulatory compliance for HACCP-based food safety management, and the first to conduct a Food Safety Culture Excellence audit in the United Arab Emirates. Findings – This article demonstrates how the concept of food safety culture works in practice, using the Food Safety Culture Excellence Model with four categories and 16 dimensions. It demonstrates how the auditing of culture within a business can highlight strengths and weaknesses and facilitate continual improvement. Originality/value – The article represents the first published model of Food Safety Culture Excellence, an extensively researched and tested model developed by Taylor Shannon International Ltd. and launched in conjunction with Campden BRI in 2014. It also demonstrates the first audit of the model in practice.

Purpose This paper aims to focus on the undergraduate research conference as its sphere of study and investigate the impact of significance of participation and socialisation in such activities on student attitudes and professional development. Using situated learning to theoretically position the undergraduate research conference as an authentic learning context, connection is also made with the concept of graduate attributes. Design/methodology/approach The Vitae (2014) Researcher Development Framework (RDF) is used to provide a template for charting the experiences and development of undergraduate students as researchers. This can be applied to short-term activities and programmes and to long-term career plans. The insights from 90 undergraduate students participating in three national undergraduate research conferences were obtained through interviews, and thematically analysed to map the students’ skills development against the RDF criteria. Findings Three main aspects of undergraduate research conference participation were considered particularly important by the students: the value of paper presentations, the value of poster presentations and the value of the overall conference experience. Within these themes, participants identified a wide range of skills and attributes they felt they had developed as a result of either preparing for or participating in the conferences. The majority of these skills and attributes could be mapped against the different domains of the RDF, using a public engagement lens for comparing actual with expected developmental areas. Research limitations/implications This research helps undergraduate research conference organisers construct programme content and form it in such a way that students’ skill development can be maximised prior to, and during, the course of an event. Learning developers can also use these findings to help understand the support needs of students preparing to deliver papers at such conferences. So far, little empirical research has examined students’ skills development within the undergraduate research conference arena. Originality/value The outcomes of this study show the diversity of the skills that students developed and the value of the conference format for offering networking practice and enhancing the communication skills which employers value.

ABSTRACTStaphylococcus aureusis a virulent pathogen that is responsible for a wide range of superficial and invasive infections. Its resistance to existing antimicrobial drugs is a global problem, and the development of novel antimicrobial agents is crucial. Antimicrobial peptides from natural resources offer potential as new treatments against staphylococcal infections. In the current study, we have examined the antimicrobial properties of peptides isolated from anuran skin secretions and cyclized synthetic analogues of these peptides. The structures of the peptides were elucidated by nuclear magnetic resonance (NMR) spectroscopy, revealing high structural and sequence similarity with each other and with sunflower trypsin inhibitor 1 (SFTI-1). SFTI-1 is an ultrastable cyclic peptide isolated from sunflower seeds that has subnanomolar trypsin inhibitory activity, and this scaffold offers pharmaceutically relevant characteristics. The five anuran peptides were nonhemolytic and noncytotoxic and had trypsin inhibitory activities similar to that of SFTI-1. They demonstrated weakin vitroinhibitory activities againstS. aureus, but several had strong antibacterial activities againstS. aureusin anin vivomurine wound infection model. pYR, an immunomodulatory peptide fromRana sevosa, was the most potent, with complete bacterial clearance at 3 mg · kg−1. Cyclization of the peptides improved their stability but was associated with a concomitant decrease in antimicrobial activity. In summary, these anuran peptides are promising as novel therapeutic agents for treating infections from a clinically resistant pathogen.

Purpose The purpose of this paper is to empirically investigate the quality tool’s impact on the effectiveness of the Hazard Analysis and Critical Control Point (HACCP)-based food safety system and correlation studies between HACCP effectiveness and business performance in food and pharmaceutical industries. Design/methodology/approach A total of 116 survey responses of prominent food and pharmaceutical firms are used to fulfil the aim of this study. The principal component analysis (PCA) method was applied to classify quality tools into a finite number of groups. Further, multiple regression methods are employed to investigate the correlation between HACCP effectiveness and firm’s performance indicators. Findings Quality tools are classified into three categories on the basis of their application by using the PCA method: quality tools for hazard identification, quality tools for hazard analysis (QTHA) and quality tools for hazard control. The regression analysis revealed that QTHA has a substantial impact on HACCP objectives (hazard identification, hazard assessment and hazard control). Additionally, the results suggest that the successful implementation of HACCP-based food safety system also delivers a direct influence on the operational and financial performance of the food and pharmaceutical industries. Originality/value This paper contributes to the existing body of HACCP knowledge by providing a framework supported by an empirical case study. The case study clustered quality tools into three broad categories related to their application of a HACCP project. Study results can guide and motivate managers to use quality tools with the aim of successful implantation of the HACCP-based food safety system, especially in food and pharmaceutical industries.

Purpose This paper aims to analyze the discourse of Arab feminism social media pages as a form of real-time new media. This is to be conducted culturally to understand the Westernized character these pages tend to propagate and the politico-cultural significations of such a propagation. Design/methodology/approach Using visual and content analysis the paper analyzes both the written and visual contents of two popular Arab feminist Facebook pages, “Thory” and “Feminist doodles” to explore its culture relevance/Westernization via the categories of “re-employing the binary second wave feminism, the historical relevance and the Westernized tone of both pages. Findings The pages showed a tendency toward second wave, Westernized, anti-orient feminism. Such importation of feminism made the pages’ message not only a bit irrelevant but also conceptually violent to a large extent. Starting from alien contexts, the two pages dislocate the Arab women experiences of their situation for the sake of comprehending and adapting to heavily Westernized images. Originality/value The paper contributes to the ongoing debate over the gender issue in the Arab context after 2011, what it originally offers is discussing the cultural relevance of popular feminist Facebook pages claiming to represent the everyday struggles of the Arab women. In addition, it shows the impact of real-time media on identity formulation.

Purpose The current complex halal food supply chain (SC) has caused food scandals, which have illustrated the weakness of multiple food quality standards and certification and audits in ensuring food safety. Drawn on the resource-based view (RBV) theory, the purpose of this study is to explore the impacts of SC integration (SCI) on halal food SC integrity and, consequently, food quality. Design/methodology/approach Empirical data were collected from 275 halal-certified food companies in Malaysia and analysed using structural equation modelling – SmartPLS3.0. Findings The results confirmed that SCI, including internal, supplier and customer integrations, has significant effects on the dimensions of the halal food SC integrity which, in turn, lead to halal food safety and quality. Practical implications The importance of SCI in halal food SC is highlighted in this study. The impact of SCI is contexted in halal food SC integrity and food quality. Therefore, it provides a clear understanding to managers of SC applicability in the halal food industry. Originality/value Based on the RBV theory, this study contributes to the limited body of research of the relationships among SCI from the context of the halal industry with a specific focus on food supply chain integrity and food quality.

ABSTRACTLactic acid bacteria can carry multiple plasmids affecting their performance in dairy fermentations. The expression of plasmid-borne genes and the activity of the corresponding proteins are severely affected by changes in the numbers of plasmid copies. We studied the impact of growth rate on the dynamics of plasmid copy numbers at high growth rates in chemostat cultures and down to near-zero growth rates in retentostat cultures. Five plasmids of the dairy strainLactococcus lactisFM03-V1 were selected, and these varied in size (3 to 39 kb), in replication mechanism (theta or rolling circle), and in putative (dairy-associated) functions. The copy numbers ranged from 1.5 to 40.5, and the copy number of theta-type replicating plasmids was negatively correlated to the plasmid size. Despite the extremely wide range of growth rates (0.0003 h−1to 0.6 h−1), the copy numbers of the five plasmids were stable and only slightly increased at near-zero growth rates, showing that the plasmid replication rate was strictly controlled. One low-copy-number plasmid, carrying a large exopolysaccharide gene cluster, was segregationally unstable during retentostat cultivations, reflected in a complete loss of the plasmid in one of the retentostat cultures. The copy number of the five plasmids was also hardly affected by varying the pH value, nutrient limitation, or the presence of citrate (maximum 2.2-fold), signifying the stability in copy number of the plasmids.IMPORTANCELactococcus lactisis extensively used in starter cultures for dairy fermentations. Important traits for the growth and survival ofL. lactisin dairy fermentations are encoded by genes located on plasmids, such as genes involved in lactose and citrate metabolism, protein degradation, oligopeptide uptake, and bacteriophage resistance. Because the number of plasmid copies could affect the expression of plasmid-borne genes, it is important to know the factors that influence the plasmid copy numbers. We monitored the plasmid copy numbers ofL. lactisat near-zero growth rates, characteristic for cheese ripening. Moreover, we analyzed the effects of pH, nutrient limitation, and the presence of citrate. This showed that the plasmid copy numbers were stable, giving insight into plasmid copy number dynamics in dairy fermentations.

PurposeOutbreak of the COVID-19 pandemic has created the catastrophic situation, it has crippled all the economic activities and seized off the operations of food supply chain (FSC). Disrupted FSC escalated the societal concerns related to food safety and security. The purpose of this study is to consolidate various issues, exploring the perspectives associated with the agricultural practices, food industries and society concerns related with the FSC performance system dynamics amid of COVID-19 pandemic.Design/methodology/approachTo structure this work, a detailed research literature insight focussing on the key findings associated with the past disease outbreaks like influenza, avian flu, Ebola, bird flu, SARS, foot and mouth disease and ongoing phase of COVID-19, encompassing the perspective related with various agricultural and concerned supply chain practices is clustered. Furthermore, issues having relevancy with the notion of this work, sourced from platforms of print and electronic media have been incorporated to ground the reality associated with the impacts, for better visualisation of the perspectives.FindingsThis study outlays the key findings which are relevant with the past pandemic outbreaks from the core of the research literature. It details the impact of the current COVID-19 scenario on the various FSC operations, focussing on dimensions allied with the industry, economic and society concerns. For the same, to mitigate the effects, relief measures focussing on the short- and long-term perspectives have been incorporated. Steps ramped up by the Government of India (GOI) to safeguard masses from the threat of food security, accelerate pace of the FSC operations and upscale operating capacities of the industries and agriculture practices have incorporated.Research limitations/implicationsPresented work is persuaded amid of the COVID-19 lockdown restrictions hence it outlays the theoretical perspectives only. But, these perspectives portray the ongoing scenario's impacts, extending its implication to the people coming from the industry and academia background. This study can felicitate the government bodies to make them familiar with the various impacts which indented the FSCs, food industries and added woes to the society concerns.Originality/valueIndia is the second largest populated nation of the world, and outspread of the COVID-19 has capsized the FSCs and raised the various instances, making population vulnerable to the threats of food insecurity. This study encompasses effect of the FSC disruption by incorporating its effect on the food industries practices, societal issues and extending possible relief measures to restructure the FSC dynamics. As of now, study focussing on the Indian FSC concerns, detailing of impacts due to pandemic outbreak, relief measures to sail out of the hard times are not available.

PurposeThis study explores Ghanaian views about accountability discharge by firms and government in the context of the nation's newly discovered oil and gas resources. The research focusses on a range of issues relating to stakeholder interaction, communication flows and the impact of decision-making on Ghanaian lives, as perceived by individuals on the ground.Design/methodology/approachThe paper adapts elements of legitimacy theory to interpret the outcome of a series of semi-structured interviews with members of key accountee and accountor groups including citizens and representatives of the state and private firms in the oil and gas industry in Ghana.FindingsThe results indicate that rather than attempting to effect substantive accountability discharge, Ghana's government and oil and gas firms employ a wide range of legitimation strategies despite the apparently complete absence of the accountee power normally seen as driving the need for social contract repair.Research limitations/implicationsThe findings suggest that accountability discharge in Ghana is cursory at best, with several legitimising strategies in evidence. The representatives from state institutions appear to share some of the concerns, suggesting that the problems are entrenched and will require robust enforcement of a strengthened regulatory approach to effect meaningful change.Originality/valueThis paper contributes to the literature on the discharge of institutional accountability by building on earlier conceptualisations of legitimacy theory to explore perceptions around a recent natural resource discovery. The analysis highlights grave concerns regarding the behaviour of state and corporate actors, one that runs counter to sub-Saharan African tradition.
