Abstract

Purpose

The Pediococcus strains belong to the group of lactic acid bacteria (LAB). This study aims to isolate and identify the Pediococcus spp. from mother’s milk, and investigate their tolerance to low pH and bile salts, antibacterial activity, attachment to HT-29 cells and effect on cholesterol-lowering and digestive enzymes in mice.

Design/methodology/approach

Pediococcus species were isolated from mother’s milk, then tested for tolerance to acid and bile salts, their antibacterial effect and attachment to HT-29 cell line. In mice experiment, the levels of triglyceride (TG), total cholesterol (TC), HDL cholesterol (HDL-C), LDL cholesterol (LDL-C) and digestive enzymes such as amylase and lipase in serum of mice were measured after administration of 108 CFU/mL bacterial suspension.

Findings

A total of 24 Pediococcus spp. including 16 isolates of Pediococcus pentosaceus and 8 isolates of Pediococcus acidilactici were isolated. Fifteen isolates (62.5%) were able to survive in low pH and bile salt concentration. Ten isolates (41.6%) exhibited the most powerful inhibitory effects against both Gram-positive and Gram-negative bacterial pathogens. A total of four Pediococcus isolates (16.67%) showed strong attachment to HT-29 cells. In contrast to HDL-C and amylase, the serum levels of TC, TG and LDL-C were reduced and lipase was elevated significantly following administration of mother milk-derived Pediococcus isolates.

Originality/value

The Pediococcus isolates demonstrated good probiotic properties in particular cholesterol-lowering ability in mice. Thus, after more studies they can be considered as probiotic strain(s).

Abstract

Purpose

Focussing on the perspective of business event leaders, this study aims to explore the future of transformative experience (TE) events, recognising a paradigm shift from organising conventional events to designing and guiding TEs in the meetings, incentives and conferences as exhibitions (MICE) context.

Design/methodology/approach

Using a qualitative interview-based design, insights from 20 international business events industry leaders were gathered and analysed by using thematic analysis through a multi-step process with MAXQDA.

Findings

The findings discuss the future of transformative events by identifying the paradigm shift towards TE in business events and outline key dimensions of the leader’s and team’s mindset and skills. Five design principles for TE events in the MICE sector are identified: design for change; emotionally experiential environments; personal engagement; responsibility; and transformative measurement.

Practical implications

The study offers a snapshot of how transformative events of the future could be designed and suggests a series of practical insights for MICE event leaders and organisers seeking to leverage events as a catalyst for intentional transformation, positive impact and long-lasting change.

Originality/value

The study adds to the emerging body of knowledge on TEs and contributes to an extended stakeholder perspective, namely, that of business event leaders and their teams who are instrumental in facilitating transformative events. An original framework for designing TE MICE events is offered as a theoretical contribution.

Abstract

Fairy tales and their movie counterparts have, for decades, been a means of socialising children and audiences regarding gender (e.g., Shewmaker, 2015; Whitley, 2013). Specifically, Disney movies that portray fairy tales have strongly influenced how young children learn gender roles and gendered behaviours, yet deeper examination is needed of how Disney portrayals of masculinities have evolved among these films and across character type to understand how Disney may be reflecting or impacting dominant representations of masculinity that privilege certain identities and characteristics over others (Brode, 2016). While previous work has examined Pixar films as socio-culturally meaningful for representations of boyhood that remain grounded in traditional, hegemonic notions of masculinity (Wooden & Gillam, 2014), this chapter adds to the body of work by employing a critical content analysis of Disney films from Snow White and the Seven Dwarfs to Disney's most recent addition of Strange World to answer the questions about how masculinities are portrayed. Through answering these questions of evolved representation throughout close to a century amount of work, we contribute to scholarship that attempts to understand media influences on boyhood culture, which is considered in crisis due to overemphasised representations of powerful, strong male characters that hide their emotions (Brode, 2016; Wooden & Gillam, 2014).

Abstract

Tourism value chain (TVC) analysis has been widely used as an alternative approach for designing sustainable and inclusive programs for tourism development in Africa, Asia, and the Pacific. This chapter looks at the experiences of three sustainable tourism initiatives in the Philippines to assess the strengths and limitations of the value chain as a framework for destination development. Short case studies describe the experiences of stakeholders in two popular destinations in the Philippines: the surfing town of San Juan, La Union, and the resort-island of Panglao, Bohol. The third case study shares the perspective of the Transforming the Tourism Value Chain (TTVC) project, a national campaign for more sustainable hotels, resort as well as meetings, conventions, incentives, and event (MICE) facilities in various destinations around the country. Stakeholders deeply involved in implementing these projects share their insights on the successes, challenges, and limitations of TVC-based approaches to resilient and sustainable destination development. The destinations' experiences suggest that the advocacy for sustainable management and operations may be comparable to a process of technology adoption or acceptance along the TVC. Practical and theoretical recommendations for leveraging the TVC toward more holistic and sustainable visitor economies are given at the end of this chapter.

Abstract

Purpose

There are many safety hazards in construction workplaces, and inattention to the hazards is the main reason why construction workers failed to identify the hazards. Reasonably allocating attention during hazard identification is critical for construction workers’ safety. However, adverse working environments in job sites may undermine workers’ attention. Previous studies failed to investigate the impacts of environmental factors on attention allocation, which hinders taking appropriate measures to eliminate safety incidents when encountering adverse working environments. This study aims to examine the effects of workplace noise and heat exposure on workers’ attention allocation during construction hazard identification to fill the research gap.

Design/methodology/approach

This study applied an experimental study where a within-subject experiment was designed. Fifteen construction workers were invited to perform hazard identification tasks in panoramic virtual reality. They were exposed to three noise levels (60, 85 and 100 dBA) in four thermal conditions (26°C, 50% RH; 33°C, 50% RH; 30°C, 70% RH; 33°C, 70% RH). Their eye movements were recorded to indicate their attention allocation under each condition.

Findings

The results show that noise exposure reduced workers’ attention to hazardous areas and the impacts increased with the noise level. Heat exposure also reduced the attention, but it did not increase with the heat stress but with subjects’ thermal discomfort. The attention was impacted more by noise than heat exposure. Noise exposure in the hot climate should be more noteworthy because lower levels of noise would lead to significant changes. These visual characteristics led to poorer identification accuracy.

Originality/value

This study could extend the understanding of the relationship between adverse environmental factors and construction safety. Understanding the intrinsic reasons for workers' failed identification may also provide insights for the industry to enhance construction safety under adverse environments.

Abstract

Purpose

This study aims to provide an explorative perspective on how workarounds – defined as practices that deviate from an official pathway to a target – delineate a decisive element for users with visual impairment to enable assistive technologies in the context of office work.

Design/methodology/approach

An ethnographic study with in situ observation at participants’ work locations together with interviews was conducted to cater for the explorative nature of this study.

Findings

The study outlines three types of workarounds that can be distinguished into: (1) own investment into invisible work, (2) engaging support from colleagues and (3) the complete circumvention of technology use. It is furthermore discussed that workarounds remain largely unnoticed but yield the potential as an enabling factor for insights into the use of assistive technology (AT).

Practical implications

The layered model of workarounds that locates them at the individual, social and organisational level can guide the design and analysis of enabling technologies in complex office work contexts. Technology designers can incorporate enquiries on workarounds into participatory or co-creative design processes. Information technology (IT) professionals and leaders of IT support teams can use this model to gain insights from workarounds into improvement opportunities for the effective integration of assistive technologies.

Originality/value

This study connects the concept of workarounds, which is deeply rooted in the tradition of workplace studies and computer-supported cooperative work (CSCW), with the practices of handling technology employed by knowledge workers with visual impairments to retain workability. This approach offers a novel perspective on the embeddedness of enabling technologies in the context of knowledge work. It highlights the intricate ways in which technology is integrated into daily work practices, thereby providing valuable insights into the intersection of AT and knowledge work.

Abstract

Purpose

The paper aims to investigate how perceived psychological benefits from employee participation in corporate social responsibility activities affect organizational citizenship behavior across two Asia–Pacific countries with different national cultures.

Design/methodology/approach

A stakeholder relationship model, based on social exchange theory, underpinned the investigation that also tested the mediating role of organizational pride. In a cross-cultural context, data were collected from 319 full-time employees in Thailand and the US and analyzed with SEM-PLS.

Findings

Anticipated psychological benefits of hedonic value and perceived community value were found to be significant antecedents of organizational citizenship behaviors, operationalized as customer-directed CSR advocacy. Organizational pride played a partial mediating role.

Originality/value

This study addresses a lack of micro-level CSR research into the relationship between psychological benefits of employee participation in CSR and organizational citizenship behavior. Specifically, this is the first study to link CSR drivers with customer-directed employee advocacy of the firms CSR activities. The study is also the first to compare relationships between an Asian and Western context for CSR drivers of organizational citizenship behaviors.

Abstract

Purpose

The manuscript aims to introduce the managerial practice of content recycling – that is, a firm's recycling of its posts on social media platforms. I define and distinguish the phenomenon from related ones and offer propositions for future research to test empirically.

Design/methodology/approach

Review of the practitioner literature, in-situ observations with content managers, and a survey of content managers and Facebook users.

Findings

Managers recycle their posts to recoup the costs of content. Under some conditions, recycled content may yield more benefits than costs.

Research limitations/implications

I define the phenomenon of content recycling and differentiate it from related terms. I offer propositions for future research.

Practical implications

I inform managers of the benefits and costs of recycling content and conditions under which benefits may override costs.

Originality/value

The research is novel and helps develop a common managerial practice.

Abstract

Purpose

This study aims to examine the relationship between the chemical composition of juices obtained from fruits of autochthonous wild pomegranate (Punica granatum L.) grown in Montenegro and their cytotoxic effects on cancer cells.

Design/methodology/approach

To explore the potential value of wild pomegranate fruits, in vitro biological assays were carried out with juices whose composition was analyzed in detail for sugars, organic acids, vitamin C and phenolic compounds. The effect of juices on survival was determined in human lung A549, cervical HeLa and breast MCF-7 carcinoma cells by MTT assay. As a control, the cytotoxicity against normal fetal lung fibroblasts (MRC-5) was monitored.

Findings

Among cancer cell lines, considering the IC50 related to total phenolics, the lowest value – 13 µg/mL was found for the A549. The strongest effect on lung cells was assumed due to the favorable contribution of ellagitannins to total phenolics in juice as well as the given combination of anthocyanins and their synergistic action. For HeLa cells, the lowest IC50 value was obtained at 88 µg/mL, and the cytotoxicity could be matched with the effects of anthocyanins and catechin. For MCF-7 cells, the lowest IC50 was 504 µg/mL, and the elevated levels of vitamin C and ellagic acid derivatives should have a noticeable effect on these cells.

Originality/value

This study provides an important contribution to the knowledge on the effect of phytochemicals from wild pomegranate juice on lung, cervical and breast cancer cells, in vitro. The present observations suggest that the juice of wild pomegranate has the potential in the fight against cancer.

Abstract

Purpose

This paper aims to examine the association between the dietary inflammatory index, the consumption of Enteral Nutrition Supplemented with probiotics with certain serum inflammation markers and gastrointestinal complications among individuals diagnosed with COVID-19.

Design/methodology/approach

This cross-sectional investigation involved 100 COVID-19 patients who were admitted to intensive care units in hospitals. These patients were administered two different types of Enteral Nutrition, so the dietary inflammatory index (DII), gastrointestinal complications and some serum inflammation markers have been compared between two groups.

Findings

The mean DII scores in all patients were significantly pro-inflammatory (probiotic formula 2.81 ± 0.01 vs usual formula group 2.93 ± 0.14 p = 0.19). The probiotic formula consumption had an inverse association with High-sensitivity C-reactive Protein concentration (coef = −3.19, 95% CI −1.25, −5.14 p = 0.001) and lead to a reduction of 2.14 mm/h in the serum level of Erythrocyte sedimentation rate compared to normal formula. The incidence of diarrhea, abdominal pain and vomiting in probiotic formula patients was respectively 94%, 14% and 86% less than in usual formula patients (p = 0.05).

Originality/value

In this cross-sectional study for the first time, the authors found that probiotic formula consumption was inversely associated with serum inflammation markers and gastrointestinal complications incidence. The high DII leads to more gastrointestinal complications incidence and inflammation markers. More studies are needed to prove this relationship.
