Abstract

Purpose

This paper aims at the problem of surrounding rock excavation damage zone of tunneling in the rich water region, this paper aims to propose a new seepage-stress-damage coupling model and studied the numerical algorithm. This reflects the characteristics of rock damage evolution, accompanied by plastic flow deformation and multi-field interaction.

Design/methodology/approach

First of all, rock elastoplastic damage constitutive model based on the Drucker–Prager criterion is established, the fully implicit return mapping algorithm is adopted to realize the numerical solution. Second, based on the relation between damage variation and permeability coefficient, the rock stress-seepage-damage model and multi-field coupling solving iterative method are presented. Finally, using the C++ language compiled the corresponding programs and simulated tunnel engineering in the rich water region.

Findings

Results show that difference evolution-based back analysis inversed damage parameters well, at the same time the established coupling model and calculating program have more advantages than general conventional methods. Multiple field coupling effects should be more considered for the design of tunnel support.

Originality/value

The proposed method provides an effective numerical simulation method for the construction of the tunnel and other geotechnical engineering involved underground water problems.

Abstract

Purpose

The purpose of this paper is to investigate idealised influence under transformational leadership and active management-by-exception (MBE-A) under transactional leadership as the predictors of employee safety behaviours among engineers and technicians in the Ghanaian power transmission subsector.

Design/methodology/approach

The study employed a cross-sectional survey design and a quantitative approach to gather data from 278 respondents through the use of a structured questionnaire. Covariance-based structural equation modelling was used to analyse the data and test the hypotheses with 264 usable responses.

Findings

The analysis revealed that idealised influence had positive significant effects on both safety compliance and safety participation of employees. Surprisingly, MBE-A had a positive influence on safety participation but not on safety compliance.

Practical implications

The findings of this study present useful practical implications for leaders and policy makers in organisations in engendering good safety behaviours of employees and improving overall organisational safety performance.

Originality/value

The variables used in the study together with the study’s Ghanaian bureaucratic context present interesting and fresh insights into the interplay between leadership and employee safety, thereby contributing to the discourse on the safety leadership construct.

Abstract

Purpose

The purpose of this paper is to present a forward-looking case of climate change induced displacement in the Pacific Islands as a multidimensional phenomenon with a moral dimension. Instead of seeking to provide a definitive solution to an imagined problem, the authors have identified the complexity of the situation through an exploration of the accounts of place and accountability for the consequences of displacement.

Design/methodology/approach

The paper explores displacement from a sociological perspective. The authors use the sociology of worth (SOW) to anchor explicit and competing moral claims in an evaluation regime that considers questions of justice and the common good. The public accounts of place in the Pacific Islands provide the empirical material for a consideration of a situated crisis. While SOW is generally adopted for current crises or disputes, this study explores the pre-immigrant story and a future case of displacement. Bauman’s (1998, 2012) perspective on globalization is used to narrate the local conditions of place in a global context as reflective of a dominant social order.

Findings

Since place is a multidimensional concept and experienced according to various states of being including physical, functional, spiritual and emotion or feeling, displacement is also felt at a multidimensional level. Thus to provide an account of a lived experience and to foster a moral accountability for climate induced displacement requires a consideration of multiple accounts and compromises that need to be considered.

Research limitations/implications

As with the majority of accounting research that is concerned with the suffering of those at a distance, we too must tackle this conundrum in a meaningful way. As members of a society that is the largest per capita emitter of greenhouse gas, how do we speak for our drowning neighbors? The paper concludes with some insights from Boltanski (1999) as a way forward.

Originality/value

The paper presents a forward-looking scenario of a looming crisis from a sociological perspective. It adds to the literature on alternative accounts by using stories, media, government reports and other sources to holistically build a narrative grounded in a current and imaged social order.

Abstract

Purpose

This study aims to explain the effect of entrepreneurial orientation (EO) dimensions on firms’ export performance. The study has considered three dimensions of EO: innovativeness, proactiveness and risk-taking. Export performance has been measured through multifaceted determinants: financial, strategic and satisfaction levels of exporting firms.

Design/methodology/approach

To explain the association between such determinants, qualitative face-to-face, in-depth interviews were conducted with the respondents from the apparel manufacturing companies of Bangladesh. The study has also applied a content analysis technique to explore and triangulate the descriptions of EO dimensions on performance.

Findings

The research results reveal that EO has a meaningful explanation of export performance from the lived experience of the respondents. The study has also found frequent explanations and indicators about the association of innovativeness and proactiveness on export performance, but the risk-taking dimension has revealed no effects.

Research limitations/implications

The research has different implications on theoretical, managerial and policy-making aspects of EO and export performance. Nevertheless, the findings are based on the opinions of a small sample of entrepreneurs and high-level managers. Thus, it is important to test the generalizability of these findings in future research using a larger sample.

Originality/value

This study indicated product, process and market creation innovativeness. Risks related to product innovation, new market entry and politics are considered for risk-taking measures, while proactive innovation, technology and new market searching are used for measuring proactiveness. Additionally, multifaceted performance determinants have been applied to evaluate export performance. Hence, this study is a unique qualitative analysis with important theoretical, practical and methodological implications.

Abstract

Purpose

This study aims to investigate the influence of transformational and transactional leadership styles and their related dimensions on safety citizenship behaviors (SCBs) in the power distribution sector (PDS) in Ghana.

Design/methodology/approach

As a cross-sectional survey approach, questionnaires were used to collect data from managers of power distribution centers. Valid questionnaires were retrieved from 197 managers across four power distribution centers. The hypotheses were tested using Pearson correlation analysis and standard multiple regression analysis.

Findings

The results revealed that both transformational and transactional leaders have a positive influence on SCBs. The results also showed that some of the dimensions of transformational and transactional leadership styles cannot strongly predict SCBs in the PDS.

Research limitations/implications

The study was limited by the use of cross-sectional data which did not allow the study to examine any changes in some of the constructs examined with time. The results are occupation-, industry- and country-specific.

Practical implications

Several management implications are discussed, such as managers recognizing that both leadership behaviors can be the basis for SCBs and for mitigating the socioeconomic consequences of unsafe employee behaviors.

Originality/value

The paper’s principal theoretical contribution is the application of social exchange theory toward an understanding of SCBs in a high-risk sector. Energy sector reforms in developing countries are inconceivable without safety consideration.

Abstract

Purpose

This study aims to examine the influence of neoliberalism and managerialism on the recruitment of tourism academics in the UK. The study analyses how sustainable the recruitment and retention of talents are in the tourism industry. Importantly, this study provides particular focus on sustainable tourism roles, as well as the impacts of COVID-19.

Design/methodology/approach

Qualitative content analysis focuses on academic jobs in tourism advertised on Jobs.ac.uk between June 2020 and July 2021.

Findings

Study findings reveal how, in the case of the UK, current educational ideologies, including neoliberalism and managerialism, significantly influence curriculum and recruitment. Such an approach facilitates the hidden curriculum of undisciplined tourism programmes and significantly constrains the prominence of sustainability principles. The development of curriculum, student life course and recruitment of academics are influenced by several variables (personal, environmental, behavioural), which must be identified to enable decision-makers to engage in efficient planning.

Originality/value

This study provides a unique focus on the recruitment of tourism academics encompassing crucial factors like sustainable tourism and COVID-19. The proposed framework creates the foundation for the investigation and discussion of academics’ recruitment in different contexts. This study also offers several new avenues for future research.

Abstract

Purpose

The purpose of this paper is to provide the historical background of genealogical records and analyze the value of Chinese genealogical research through the study of names and genealogical resources.

Design/methodology/approach

The paper examines the historical evolution and value of Chinese genealogical records, with the focus on researching the Islamic Chinese names used by the people living in Guilin. The highlight of this paper includes the analysis and evolution of the Islamic Chinese names commonly adopted by the local people in Guilin. It concludes with the recommendations on emphasizing and making the best use of genealogical records to enhance the research value of Chinese overseas studies.

Findings

The paper covers the history of Islam and describes how the religion was introduced into China, as well as Muslims' ethnicity and identity. It also places focus on the importance of building a research collection in Asian history and Chinese genealogy.

Research limitations/implications

This research study has a strong subject focus on Chinese genealogy, Asian history, and Islamic Chinese surnames. It is a narrow field that few researchers have delved into.

Practical implications

The results of this study will assist students, researchers, and the general public in tracing the origin of their surnames and developing their interest in the social and historical value of Chinese local history and genealogies.

Social implications

The study of Chinese surnames is, by itself, a particular field for researching the social and political implications of contemporary Chinese society during the time the family members lived.

Originality/value

Very little research has been done in the area of Chinese local history and genealogy. The paper would be of value to researchers such as historians, sociologists, ethnologists and archaeologists, as well as students and anyone interested in researching a surname origin, its history and evolution.

Abstract

Purpose

This paper aims to discuss innovations in the training and development practices of companies and delineate a new approach to training and development in the context of the hybrid workplace using the ADDIE and Kirkpatrick training models.

Design/methodology/approach

This paper discusses innovations in training and development in modern times and builds on the instructional training design approach or the ADDIE Model and the Kirkpatrick Model of training evaluation.

Findings

The paper presents new approaches to training and development in the context of the hybrid work model applying the ADDIE Model and the Kirkpatrick Model. These new approaches are both necessitated and also made possible due to the technological advancements of modern times.

Originality/value

With the rapid transition of companies to the hybrid model of work in recent times, several human resource management practices need to be transformed to suit the requirements of the new work model. Training and development is one function that needs to change in the hybrid work model to ensure its effectiveness. This paper analyses innovations in the training and development practices of companies and discusses new approaches while applying existing training models, the ADDIE and Kirkpatrick Models, to adapt to the changes associated with the hybrid work model.

Abstract

Purpose

The purpose of this study is to investigate the effect of olive cake (OC) on oxidant/antioxidant biomarkers, lipase activity and on the histological analysis of epididymal fat, in high-fat diet (HFD)-induced obese rats.

Design/methodology/approach

Male obese rats were divided into two groups and were fed an HFD supplemented (HFD-OC) or not (HFD) with OC for 28 days. A control group was fed a standard diet for the same experimental period.

Findings

HFD significantly increased body weight, which was reduced by OC in the HFD-OC compared to HFD (p = 0.038). Lipase activity was higher (52%; p = 0.009) in the HFD group than the control group. Administration of OC to the obese rats decreased significantly this activity (38%; p = 0.025) compared to the HFD group. Serum thiobarbituric acid-reactive substances, lipid hydroperoxide and advanced oxidation protein products levels were significantly increased in the HFD group than the control group (p = 0.032, p = 0.023 and p = 0.017, respectively). These levels were significantly reduced in HFD-OC compared to the HFD group (p = 0.030, p = 0.021 and p = 0.010, respectively). Superoxide dismutase, glutathione peroxidase and catalase activities were decreased (53%; p = 0.04), (61%; p = 0.03) and (32%; p = 0.002), in the HFD group than the control group. OC restored these activities (46%; p = 0.01), (58%; p = 0.003) and (30%; p = 0.0003) in the HFD-OC rats than the HFD rats. Consumption of the HFD resulted in adipocyte hypertrophy. Indeed, epididymal adipocyte size was significantly larger in the HFD group than the control group (p = 0.0001), whereas it was reduced in the HFD-OC compared to the HFD group (p = 0.012).

Originality/value

OC possesses an anti-obesity effect. This effect might be mediated by lipase inhibition, reduced oxidative stress and increased antioxidant activities. In addition, the reduction of fat accumulation in adipose tissue by OC consumption is reflected by reducing adipocyte size.
