This paper aims to provide a method for obtaining physically sound temperature fields to be used in geophysical inversions in the presence of immersed essential conditions.

Abstract

Purpose

This paper aims to provide a method for obtaining physically sound temperature fields to be used in geophysical inversions in the presence of immersed essential conditions.

Design/methodology/approach

The method produces a thermal field in agreement with a given location of the interface between the Lithosphere and Asthenosphere. It leverages the known location of the interface to enforce the location of a given isotherm while relaxing other constraints known with less precision. The method splits the domain: in the Lithosphere the solution is immediately obtained by standard procedures, while in the Asthenosphere a minimization problem is solved to fulfill continuity of temperatures (strongly imposed) and fluxes at the interface (weakly imposed).

Findings

The numerical methodology, based on the relaxation of the bottom fluxes, correctly recovers the thermal field in the complete domain. To obtain bottom fluxes following geophysical expected values, a constrained minimization strategy is required. The sensitivity of the method could be improved by relaxing other quantities such as lateral fluxes or mantle velocities.

Originality/value

A statement of the energy balance problem in terms of a known immersed condition is presented. A novel numerical procedure based on a domain-splitting strategy allows the solution of the problem. The procedure is tailored to be used within geophysical inversions and provides physically sound solutions.

Abstract

Purpose

This paper aims to explore the integration challenges during the early stages of implementation of value streams as team aggregation structures as a novel organizational construct in a modern organization.

Design/methodology/approach

We use an immersive ethnographic approach to follow the transition to value streams as team aggregation structures in a large organization during the first three years of implementation. We integrate systematic observations with interviews to get insights into the dynamics of change and the most important challenges faced by the organization during this transition.

Findings

We integrate systematic observations collected during the organizational change with insights from interviews carried out with managers to provide tentative answers to some key questions related to the implementation of multiteam systems. We reflect on their performance, entitativity, autonomy as well as on the satisfaction of their members.

Practical implications

We discuss some of the most important managerial challenges during the transition to value streams as novel organizational constructs and we derive some actionable insights for team and value stream managers leading such change processes.

Originality/value

Our study provides a rich account of the first stages of implementing an organizational design that brings together different teams in organizational structures that are focused on the value provided to customers.

Abstract

Purpose

The purpose of this study was to examine how two socio-historical contexts within the United States, the Movement for Black Lives and the COVID-19 pandemic, informed approaches to improving racial climate in science, technology, mathematics and engineering (STEM) graduate education.

Design/methodology/approach

The authors used a general qualitative inquiry research study design to conduct focus groups (n = 121) with graduate students, postdoctoral fellows and faculty members from across STEM disciplines as well as administrators whose work involves STEM graduate students. Participants were from two US institutions involved in a National Science Foundation networked improvement community seeking to create inclusive environments for STEM graduate students.

Findings

This study demonstrates how these socio-historical contexts illuminated and amplified on-going efforts to address racial climate for graduate students in US-based graduate education. In response to these events, STEM faculty devoted time that otherwise might have gone to purely technical or scientific endeavors to addressing racial climate. However, some faculty members remain hesitant to address racial climate and efforts appear to have further waned over time. While diversity, inclusion and equity efforts came to the forefront of the collective consciousness during this time, participants worry that these efforts are not sustainable, particularly without support from faculty and administrators.

Practical implications

The findings from this study will inform efforts to improve racial climate in STEM graduate programs.

Originality/value

This study fills an identified need to capture how socio-historical contexts, like the US Movement for Black Lives and the COVID-19 pandemic, have influenced approaches to improving racial climate in STEM graduate programs.

Abstract

Purpose

This study aimed to evaluate the compositional changes and bioaccessibility of phenolics and antioxidants in propolis during in vitro digestion as well as the cytotoxic effects of digested propolis on various cancer cell lines.

Design/methodology/approach

Six propolis samples were obtained and subjected to in vitro oral, gastric and intestinal digestion. Both digested and undigested samples were analyzed for their total phenolic, flavonoid and antioxidant activities. Additionally, changes in phenolic composition in the in vitro digestion system were revealed by the HPLC-DAD system. The cytotoxic effects of the digested samples were assessed on lung (A549, H1299), skin (A431), liver (Hep-G2) and colon (Caco-2) cancer cells as well as on fibroblast (Bj) cells.

Findings

The mean bioaccessibility values of phenolic and flavonoid compounds were found to be less than 35 and 24%, respectively, while the TEAC and CUPRAC antioxidant results ranged between 225.08–649.04 and 398.68–1552.28 µmol TE/g, respectively. The release of p-coumaric, ferulic, 3,4-dimethoxycinnamic acids, naringenin, pinocembrin and chrysin increased progressively from the oral to the intestinal stage. The cytotoxic effects of samples on cell lines were ranked, based on IC50 results, as A431 > Hep-G2 > Caco-2 > A549 > H1299 > Bj.

Originality/value

Propolis has been recognized for centuries as a natural remedy, and numerous studies have explored its bioactive components. However, no studies have previously examined the changes in the phenolic compositions of propolis samples during digestion or their cytotoxic effects on cancer cells. Therefore, this study provides novel insights and an approach to the existing literature on this topic.

Abstract

Purpose

Disaster research is often geared towards logocentrism and has relatively few outputs that explore alternative forms of representation, particularly those using an artistic medium. This paper explores how the creative use of audio representation can enhance understanding of flooding experiences, challenging the predominant text-based approach within qualitative study.

Design/methodology/approach

During a series of visits to people who had been flooded in 2019 in the UK, interviews and ambient sounds were recorded, analysed and then intertwined with musical elements composed by the lead author. The result is a phonographic representation of the synthesised data. The process explores a tripartite, creative, sonic approach that comingles thematic spoken excerpts with local sounds and musical compositions.

Findings

This article presents three sonic vignettes that illustrate the use of audio as a medium for academic research outputs. It contributes to the current consensus that the interpretation, representation and dissemination of research findings should be broadened beyond the dominance of the written word to align with the ethos of the Disaster Studies Manifesto.

Research limitations/implications

The research contributes to disaster scholarship by developing a transdisciplinary approach to explore people’s experiences. By retaining the participants’ voices at its core, it makes use of in-depth, rich data to illustrate individuality, rather than aiming to generalise.

Originality/value

Very little disaster research has focussed on pushing the boundaries of investigation by using the arts as a lens for both the researcher and their audience. Such work may connect with a wider range of people compared to a text-based “traditional” academic output. It can offer new opportunities for practical uses within Disaster Risk Reduction, for example as a communicative and educational tool.

Contribution to impact

This paper contributes to understanding the impact of developing audio representation as a medium for conveying people’s experiences of flooded homes.

Abstract

Purpose

A pronounced rise in postpandemic immigration is creating consumption opportunities and challenges for countries worldwide. Past research has shown that immigrant homeownership indicates advanced consumer acculturation. However, critical factors which differentiate immigrant decisions to purchase a home remain underexplored. This study aims to examine the importance of different identity resources in determining homeownership gaps between immigrant groups in Spain during a dynamic decade.

Design/methodology/approach

A mixed methods research design with triangulation was used. First, the critical “historical research method” is used to empirically assess 15,465 household-level microdata files from the National Immigrant Survey of Spain. Second, the analysis is corroborated through informant interviews, an evaluation of digital news archives and other historical traces such as relevant advertisements in Spain from 2000 to 2009.

Findings

Results provided an account of immigrant homeownership whereby foreign-born consumers leveraged resources to promote social identities aligned with an advanced level of acculturation through housing investment during this period. Furthermore, marketing focused on specific targets of ethnic minority consumers coupled with government policies to promote immigrant homeownership reinforced the “Spanish Dream” as a new paradigm for housing market integration.

Originality/value

Spain provides an unprecedented historical context to explain marketing-related phenomena due to a perfect storm of immigration, job availability and integration supports. Contrary to popular wisdom, immigrant consumer homeownership gaps are not solely a result of differences in income and economic mobility, but rather an advanced acculturation outcome driven by personal and social investments in resources that lead to consumer identities.

Abstract

Purpose

This paper presents a pioneering investigation into the barriers impeding the adoption of reverse logistics (RL) in the Iranian construction industry, addressing a significant gap in the current literature within the country.

Design/methodology/approach

Through a meticulous examination of the literature, complemented by 19 in-depth interviews, a battery of barriers to RL implementation was initially identified, distilled into a final set of 30 barriers, which served as the basis for the design of a structured survey questionnaire. Employing Partial Least Squares–Structural Equation Modeling (PLS-SEM), an analysis was conducted on a dataset that comprised of 80 responses. Subsequently, the barriers approved through the PLS- SEM were subjected to prioritization through the application of Fuzzy TOPSIS.

Findings

Findings reveal the critical inadequacy of contemporary technology and infrastructure, a foundation essential for the efficacious enactment of RL. This shortfall manifests in procurement and logistics processes plagued by inefficiency and ineffectiveness, as consequences of an immature information and technology ecosystem. Furthermore, the study underscores the dominance of traditional markets where the adoption of secondary materials/products remains sporadic, signaling a crucial area for further research and intervention.

Originality/value

This study offers original insights into the significant hurdles that hinder the adoption and integration of RL practices within the Iranian construction industry, an under-explored area within the RL research domain. For industry practitioners, findings point to recommendations for overcoming these barriers in the specific Iranian context while also offering broader insights and lessons that may be relevant to other countries and similar contexts.

Abstract

Purpose

This study aims to address existing gaps in the literature and theories by investigating the influence of responsible leadership traits on employees’ sustainable performance (E-SuPer) in the Malaysian service sector. Specifically, the authors focus on three key responsible leadership traits: relationship building, relational governance and sharing orientation. Additionally, the authors explore how these traits interact with leader-member exchange (LMX) and whether gender plays a role in this relationship.

Design/methodology/approach

A total of 235 usable responses were analysed using partial least squares structural equation modelling. Multi-group analysis (MGA) was employed to examine the moderating impact of gender.

Findings

The results showed that both relationship building and relational governance significantly affect E-SuPer among organisations in the service industry. LMX was found to be a significant moderating condition influencing the association between responsible leaders’ sharing orientation and E-SuPer. Interestingly, the MGA results suggest that the effect on male employees was greater than on female employees across the relationships examined. The findings suggest that responsible leadership traits are essential for sustainable employee performance, but there is room for improvement in how these traits are perceived by female employees.

Social implications

The present study contributes to gender equality agenda, supports the sustainable development goals, adds to the growing body of knowledge on the relationship between responsible leadership traits and E-SuPer within one of the most important economic sectors in Malaysia and sheds lights on the moderating effect of LMX.

Originality/value

This study investigates how responsible leadership traits affect E-SuPer in the service industry, particularly among male and female employees. Moreover, this study is one of the early investigations into the significance of responsible leadership within Malaysian service sector and offers valuable information for industry actors to improve their management approaches.

Abstract

Purpose

The study examines the residential facades of the Al-Jadida neighborhood, focusing on the use of geometry and proportion in Aleppo's architectural history during the late Ottoman era. The analysis sheds light on the city's past and provides insights into the way residents utilized space and interacted with their surroundings.

Design/methodology/approach

The study involves collecting primary and secondary sources, including historical documents, photographs, and drawings. Visual analysis is employed to examine the facades overlooking the courtyard, with a focus on windows, doors, balconies, and other distinctive features that contribute to the overall courtyard design.

Findings

The findings reveal that traditional Aleppine architecture is centered around the courtyard and incorporates decorative openings and windows reflecting Islamic principles. Stone decorations are used with unique designs based on geometry and composition, contributing to Aleppo's cultural identity.

Research limitations/implications

Including more samples for studying facades allows for the identification of changes in architectural styles and the influence of different cultural influences on the city's architecture over time. Moreover, conducting further studies is crucial for preserving this important part of Aleppo's history for future generations.

Originality/value

This research analyzes architectural facades in late Ottoman Aleppo, offering insights for future studies and understanding architectural design development. It also informs preservation efforts for historic buildings, enhancing understanding of architectural features and characteristics.

Abstract

Purpose

The importance of innovation has attracted growing attention due to the complex and rapidly changing business environment. This study aimed, first, to examine the joint effect of servant and authentic leadership (AUL) styles on employee creativity (EC), second, to examine the direct and mediated effect of servant leadership (SL) on employees' innovative work behaviour (IWB), third, to examine the effect of EC on IWB and finally, to investigate the moderating effect of creative self-efficacy (CSE) on the relationship between AUL and EC.

Design/methodology/approach

A quantitative approach was used, and the data were collected from 446 employees in the Qatari public sector. The data were then analysed by employing partial least squares structural equation modelling (PLS-SEM) using SmartPLS software to validate the measures before testing the proposed model.

Findings

The results of this study emphasized the strong hypothesized link between EC and IWB. It also endorsed the mediating role of EC between SL and IWB and the moderating role of CSE in the AUL-EC relationship.

Originality/value

The originality of this study comes from various aspects. First, it is unique in separately examining EC and innovation and the link between them. Second, it investigates the joint impact of servant and AUL styles on EC. Third, it explores the mediating role of EC between SL and IWB. Fourth, the moderating effect of CSE on the AUL-EC link also was examined to gain a full understanding of the relation effect. Finally, the value of the current study also comes from the integration of the triangular theory of creativity, SL and AUL theories and self-efficacy theory to explain the proposed model of the study. Moreover, this study serves as a guideline for decision-makers on how to enhance IWB among employees by focusing on leadership programmes and the creative and innovative culture.
