Abstract

Purpose

The purpose of this study is to fabricate an ultraviolet (UV) metal-semiconductor-metal (MSM) photodetector based on zinc oxide nanorods (ZnO NRs) grown on seeded silicon (Si) substrate that was prepared by a low-cost method (drop-casting technique).

Design/methodology/approach

The drop-casting method was used for the seed layer deposition, the hydrothermal method was used for the growth of ZnO NRs and subsequent fabrication of UV MSM photodetector was done using the direct current sputtering technique. The performance of the fabricated MSM devices was investigated by current–voltage (I–V) measurements. The photodetection mechanism of the fabricated device was discussed.

Findings

Semi-vertically high-density ZnO (NRs) were effectively produced with a preferential orientation along the (002) direction, and increased crystallinity is confirmed by X-ray diffraction analysis. Photoluminescence results show a high UV region. The fabricated MSM UV photodetector showed that the ZnO (NRs) MSM device has great stability over time, high photocurrent, good sensitivity and high responsivity under 365 nm wavelength illumination and 0 V, 1 V, 2 V and 3 V applied bias. The responsivity and sensitivity for the fabricated ZnO NRs UV photodetector are 0.015 A W-1, 0.383 A W-1, 1.290 A W-1 and 1.982 A W-1 and 15,030, 42.639, 100.173 and 334.029, respectively, under UV light (365 nm) illumination at (0 V, 1 V, 2 V and 3 V).

Originality/value

This paper uses the drop-casting technique and the hydrothermal method as simple and low-cost methods to fabricate and improve the ZnO NRs photodetector.

Abstract

Purpose

The purpose of this study is to dope silver (Ag) and fluorine (F) in zinc oxide (ZnO) for the enhancement of electrical and optical properties of ZnO, as previous studies reported the improvement of these properties using individual doping of F and Ag. In this paper, F and Ag co-doped ZnO nanorods were synthesized using a modified hydrothermal method.

Design/methodology/approach

The hydrothermal method was modified and used for the synthesis of the doped ZnO nanostructures, where stainless autoclave and oven were replaced with the Duran laboratory bottle and water boiler system in the process. The ultraviolet metal-semiconductor-metal photodetector (PD) was fabricated using DC sputtering method.

Findings

Vertically aligned nanorods images were captured from field emission scanning electron microscopy. XPS analysis confirmed greater spin-orbital interaction in the F and Ag co-doped ZnO sample and revealed the presence of F, Ag, Zn and O in the samples, indicating a successful doping process. X-ray diffraction revealed a hexagonal wurtzite structure with enhanced crystal quality upon co-doping. The bandgap decreased from 3.19 to 3.14 eV upon co-doping because of reduced defects density in the sample. Finally, an ultra-violet PD was fabricated with enhanced sensitivity and response times upon co-doping.

Originality/value

The low-cost, less energy-consuming Duran laboratory bottle and water boiler system were used as the substitute of expensive, more energy-consuming stainless autoclave and oven in a hydrothermal method for synthesis of F and Ag co-doped ZnO and subsequent fabrication of PD.

Abstract

Purpose

This study aims to assess the possibility of adapting evidence-based policies in the daily operations of tour operators in Semporna, Sabah, Malaysia. This intervention is important, as on-site investigations reveal that operators are operating their businesses with little reference to the ecotourism policy guidelines.

Design/methodology/approach

This study adopted a full qualitative approach. In-depth interviews were conducted on tour operators in Semporna, while text mining was used to elicit data from the Malaysian National Ecotourism Plan. Thematic analysis was used to analyse the data from the primary sources.

Findings

Gaps were evident between best practices guidelines from the National Ecotourism Plan and the day-to-day practices of tour operators in Semporna, Sabah. This was due to the limitations of the National Ecotourism Plan and the limitations of the operators in identifying and adhering to best practices; the impracticality of best practices in site-specific scenarios; and the benefit of adapting evidence-based practices (ECP) in Semporna, Sabah.

Practical implications

The implications of this study include a plan to bring forth a non-parochial and innovative approach in rural tourism policymaking process and to advocate evidence-based intervention through the inclusion and participation of stakeholders.

Originality/value

This study contributes towards the requisite of evidence-based intervention for rural tourism policies to meet site-specific needs.

Abstract

Purpose

The purpose of this paper is to investigate how socioeconomic status and demographic factors were associated with child malnutrition as well as how these factors accounted for socioeconomic inequality of child malnutrition in Bangladesh during 2007-2011.

Design/methodology/approach

Data of this study come from two cross-sectional rounds (2007 and 2011) of the Bangladesh Demographic and Health Survey. This paper uses ordinary least square models to estimate the correlates of child malnutrition. The study further uses the concentration curve and the concentration index to estimate socioeconomic inequality of child malnutrition in Bangladesh. Finally, the decomposition method is used to explain socioeconomic inequality of child malnutrition in the study period.

Findings

Regression analysis indicates that child’s age, breast feeding, child’s birth order, the number of under-five child in the household, household wealth and parental education were strongly correlated with child malnutrition in Bangladesh. This study finds that absolute level of child malnourishment slightly decreased between 2007 and 2011, but socioeconomic inequality increased during this period. Children from the poorest household endured the burden of malnourishment more than those from the wealthiest households. The level of inequality also increased among the rural children, although it remained stagnant among the urban children. Decomposition analysis highlights that parental education had a significant negative relation with the average level of malnutrition, but its role was primarily centred among children from wealthier households.

Practical implications

An approach linking the ministry of health and education with other ministries may speed up the reduction of inequalities in social determinants of childhood undernourishment. Most importantly, there is a need for comprehensive government policies to reduce growing economic inequality and increase the relative income of the poor in Bangladesh.

Originality/value

This study is the first of its kind to apply the decomposition method to explain the socioeconomic inequality of child malnutrition in Bangladesh. This paper presents an enriched understanding of socioeconomic inequality of child malnutrition in Bangladesh during 2007-2011.

Abstract

The impact of conflict and violence is not only limited to the conflict region itself, but it usually extends to neighboring countries and regions. The Syrian conflict is an example of border-sharing countries hosting a million refugees and re-adapting to the new situation. This case highlights the corporate social responsibility initiative of a Lebanese businessman and business owner in 2019. It explains how this businessman and his company reacted to the waves of Syrian refugees moving to his city in Lebanon. More particularly, it describes the pro-active reaction of the company during the Syrian refugee crisis in Lebanon and how this reaction has transformed from a donation-based to business-based solution and rearranged its priority to help Syrian refugees. The philanthropic experience of the company before the refugee crisis was donation-dominated. The case also outlines the forms the company and its owner have designed to provide traditional aids (shelters, food, and clothes) and creating jobs for refugees. It shows the need to change the managerial behavior and perspectives due to the unusual situation of conflict. This situation has created a unique experience of corporate social responsibility in Lebanon as an example of a refugee-hosting country.

Abstract

This chapter focuses on discussing the Malaysian government's ‘No Plastic Bag Day’ campaign. This is due to the fact that consumers are accustomed to use plastic bag in their daily life activities. However, considering the hazardous impact on the environment, the government has banned the use of plastic bag in most of the states. While many consumers accepted this new rule whole-heartedly, many are still struggling to adopt it. This chapter highlights its journey of implementation and challenges pertaining to this sustainability marketing campaign in Malaysia.

Abstract

Purpose

This paper aims to explore how sustainability practices were implemented in a higher education institution within a local setting in the Gulf and Arab Emirates Region. This study examined the impact of social and cultural requirements on the development of the master plan for the New Kuwait University campus with regards to sustainability to illustrate how current social and cultural requirements impact the design of a future learning environment whilst highlighting the essential role of organisational actors in this implementation process.

Design/methodology/approach

Using an in-depth case study approach, the authors conducted 21 semi-structured interviews with educators and administrative staff who had been involved in the sustainability implementation process at Kuwait University. These participants were involved at different stages in the implementation of a major sustainability project at Kuwait University. The interviews were further supplemented by analysing supporting documents and communications.

Findings

The analysis reveals that sustainability was embedded in a narrative that was repeated at the practice level; this directed the setting of objectives for the project and its various sub-tasks. It also helped actors to develop their understandings of practice and the importance of social emotions, self-intentions and patterns of culture in the process. This study further reveals that participants mainly focused on environmental issues regarding saving paper/electricity and overlooked aspects of a wider concepts and core values of sustainability, and there is a significant amount of lack of knowledge and awareness on matters about sustainability, especially with the understanding of its definition.

Originality/value

This study draws on practice-organisation framework used by Schatzki (2002, 2010), suggesting that sustainability implementation is a process led by rules, practical understanding, general understanding and teleoaffective structures, to highlight the role of agency and change among various actors in implementing sustainability. A practice-theory framing is used to signpost the roles played by various actors in establishing goals and tasks for the project while taking account of local understanding and independence in the implementation of sustainability practices. Engaging with practice theory framework offers us theoretical basis that is fundamentally different from the theories of interaction-oriented approaches in sustainable design.

Abstract

Purpose

The present study attempts to shed some light on tourists’ destination brand loyalty (DBL) in the Malaysian ecotourism context. More specifically, this study aims to examine the relationships between electronic word of mouth (eWOM), destination brand quality (DBQ), destination brand image (DBI), psychological engagement (PE) and DBL.

Design/methodology/approach

Based on the Stimulus–Organism–Response theory and buyer black box model, this study developed a framework to address tourists’ loyalty towards ecotourism destinations. An online survey was carried out to collect data, which yielded 210 completed usable responses. Structural equation modelling – partial least squares was used to test the study hypotheses.

Findings

Findings from this study revealed that eWOM and destination product quality affect DBI. Moreover, data support the mediating effect of PE between DBI and DBL.

Practical implications

This study provides valuable insights for practitioners and policymakers of the tourism industry in creating a DBI, keeping tourists psychologically engaged and retaining their loyalty to the ecotourism destinations.

Originality/value

This study is amongst the first to examine the effect of eWOM and DBQ on DBI in the ecotourism context. It also examines PE in relation to the DBI, which is a comparatively new area in the literature.

Abstract

Purpose

This study aims to evaluate the impacts of human capital factors in terms of spiritual intelligence (SI), emotional intelligence (EI) and workplace attitude in terms of trust on organizational sustainability (OS) in the hotel industry in Malaysia. In addition, this study intends to examine the mediation role of trust between human capital factors and OS.

Design/methodology/approach

A survey method using a questionnaire was used to collect data from 361 employees, including middle management, who are in direct contact with guests in the hotel industry. The partial least squares technique, SmartPLS3.3.3, was used to examine the hypotheses.

Findings

The analysis found support for the impacts of SI, EI and trust on OS. Additionally, the mediation effect of trust was also supported.

Originality/value

This pioneering study has combined human capital factors (i.e. SI and EI) to predict their effects on OS in the hotel industry. Moreover, this research established relatively new relationships between SI and OS and between EI and OS through the mediation role of trust. Furthermore, this study confirmed the validity and reliability of SI, EI and OS at first and second orders. Given the adverse impact of COVID-19 and its variants on the sustainability of all business organizations, this research has highlighted the crucial role of human factors and workplace attitude in the sustainability of the hospitality sector during difficult times.

Abstract

Purpose

This paper aims to examine the factors that drive the exporter’s influence toward halal meat supply chain adoption by encompassing the diffusion of innovation (DOI) theory in the context of Pakistan.

Design/methodology/approach

Using DOI as an underpinning theory, this study evaluates halal supply chain adoption by collecting data from the members of associations from Pakistan. A total of 258 useable responses were received, and PLS-SEM was adopted using SmartPLS.

Findings

The exporter’s adoption of the halal supply chain is determined not only by perceived relative advantage and perceived compatibility but also by perceived complexity, religious beliefs and awareness.

Research limitations/implications

Though this study has practical and managerial implications, it has few limitations. Further studies need to be conducted in other contexts as well with a larger population.

Originality/value

There are limited studies that have tested DOI theory in the context of the halal meat supply chain in Pakistan. Therefore, the author extends the diffusion theory of innovation in the current work. Further, this paper will be a helpful reference guide for academicians, practitioners and researchers.
