Hydrodynamic instabilities of propagating interfaces under Darcy's law
Authors: Daou Joel , Rajamanickam Prabakaran 
Published: January 2025

The hydrodynamic instabilities of propagating interfaces in Hele-Shaw channels or porous media under the influence of an imposed flow and gravitational acceleration are investigated within the framework of Darcy's law. The stability analysis pertains to an interface between two fluids with different densities, viscosities, and permeabilities, which can be susceptible to Darrieus-Landau, Saffman-Taylor, and Rayleigh-Taylor instabilities. A theoretical analysis, treating the interface as a hydrodynamic discontinuity, yields a simple dispersion relation between the perturbation growth rate s and its wave number k in the form s=(ak−bk2)/(1+ck), where a, b, and c are constants determined by problem parameters. The constant a characterizes all three hydrodynamic instabilities, which are long wave in nature. In contrast, b and c, which characterize the influences of local curvature and flow strain on interface propagation speed, typically provide stabilization at short wavelengths comparable to the interface's diffusive thickness. The theoretical findings for Darcy's law are compared with a generalization of the classical work by Joulin and Sivashinsky, which is based on a Euler-Darcy model. The comparison provides a conceptual bridge between predictions based on Darcy's law and those on Euler's equation and offers valuable insights into the role of confinement on interface instabilities in Hele-Shaw channels. Numerical analyses of the instabilities are carried out for premixed flames using a simplified chemistry model and Darcy's law. The numerical results corroborate with the explicit formula with a reasonable accuracy. Time-dependent numerical simulations of unstable premixed flames are carried out to gain insights into the nonlinear development of these instabilities. The findings offer potential strategies for control of interface instabilities in Hele-Shaw channels or porous media. Special emphasis is given to the critical role played by the imposed flow in destabilizing or stabilizing the interface, depending on its direction relative to the interface propagation.

Characteristics of individuals using an integrated intensive support team within an adult community learning disability team
Authors: Durand Marianne , Hanna Mary , Mills Rachel 
Published: January 2025

Purpose
This paper aims to describe characteristics of individuals known to an integrated intensive support team (IST) for adults with intellectual disabilities (age, sex, ethnicity, level of intellectual disability, diagnoses). This paper also aims to report on community service input, the use of Dynamic Support Database-Clinical Support Tool, Care and Treatment Reviews and admissions and discharges from mental health hospitals.

Design/methodology/approach
A retrospective cohort study using routinely collected data over a two-year period.

Findings
Around 90 individuals aged 19–73 years were rated as at risk of admission to mental health hospital, using the Dynamic Support Database-Clinical Support Tool. There were more men (62%) than women. Almost half (47%) had a mild intellectual disability, and around a third (37%) were autistic. Of the 63 individuals known to the team who were rated red (imminent risk of admission), three individuals were admitted to hospital. Therefore, 95% of potential admissions were avoided.

Practical implications
This adds to the emerging evidence of the utility of ISTs integrated within community learning disability teams in reducing admissions to hospital.

Originality/value
To the best of the authors’ knowledge, this study is the first to evaluate IST outcomes using the Dynamic Support Database-Clinical Support Tool.
Hispanics in the workplace: their job demands and resources
Authors: Black Stephanie , Guerrero Laura , Blancero Donna Maria 
Published: January 2025

PurposeThis conceptual paper seeks to contribute to the literature on Hispanics in the workplace by applying the job demand-resource (JD-R) model to better identify some of the unique demands, resources and outcomes that have been studied within Hispanic populations. Specifically, we apply moderators that uniquely differentiate Hispanic workers from the more dominant White culture.Design/methodology/approachOur search revealed peer-reviewed papers from 1970 to 2019. This timeframe was chosen because earlier studies did not report findings specifically about Hispanics. We excluded papers that: (1) focused on measurement equivalence, were qualitative or conceptual, (2) were not related to workers or employees (3) examined outcomes not resulting from demands and resources, (4) studied Hispanics not living in the US or (5) did not report independent findings on Hispanics. Based on our parameters, a total of 82 articles have been included in our study.FindingsOur literature review revealed a tendency to treat Hispanics as a homogeneous group rather than delving into their distinct characteristics. Consequently, our model and propositions offer a framework to thoroughly investigate the unique attributes of Hispanics in the workplace.Practical implicationsThis paper aims to encourage further research on Hispanics in the workplace, fostering a deeper understanding among organizations and managers to create a work environment that is more inclusive and conducive to productivity.Originality/valueThis paper enhances the literature on Hispanics in the workplace by presenting a model and propositions grounded in JD-R theory, with a specific focus on exploring factors that impact the job-related outcomes of Hispanics.
Supported internships: vocational training and labor inclusion for students with intellectual and developmental disabilities
Authors: Folguera Bellmunt Conxita 
Published: January 2025

PurposeThis research analyzes the preparation of students with intellectual and developmental disabilities (IDD) for inclusion in the open labor market via supported employment (SE). To this end, Fraser’s (1995) concept of transformative action is used to evaluate changes in students’ attitudes and behaviors.Design/methodology/approachA qualitative approach was adopted, consisting of interviews with SE organizations and observations of students participating in workshops focused on internships that form part of their educational process.FindingsThe research findings indicate that an educational approach to SE inclusion can generate transformative processes that contribute to changing the conditions leading to exclusion from the labor market.Research limitations/implicationsThis research develops further the use of Fraser’s (1995) theorization in disability studies. Students were observed participating in workshops, and not in their workplaces, which represents both a limitation and a line for future investigation.Practical implicationsThis research contributes to reducing managers’ reluctance to contract people with IDD. It is also useful for those secondary schools implementing an inclusive educational approach that are willing to include internships as part of their academic curriculum.Social implicationsGreater investment and cooperation by education and labor policy makers are needed to make inclusion possible.Originality/valueThis study investigates inclusion in the labor market as part of the educational development of students with IDD, focusing on its transformative nature.

Detecting and analyzing weak signals of change in futures research and foresight
Authors: Shaeva Olga , Khlopov Nikolay 
Published: January 2025

Purpose
This paper aims to outline current and emerging opportunities and challenges in applying collective intelligence methods to detection and analysis of weak signals of change.

Design/methodology/approach
The article builds on review of current literature on the topic and analysis of projects employing various methods of collective intelligence to scanning and sense making for signals of change.

Findings
The article points out possible roles of collective intelligence in analysis of weak signals, specific to the scanning and sensemaking stages in futures research. It identifies key variations of applying collective intelligence to weak signals that shape the result of the research process: selection of participants for collective intelligence (from controlled to open) and ways of collaboration in the collective intelligence process (from fully collective to switching between collective and individual mode). It also gives an example of a successful application of collective intelligence to weak signals analysis and suggests possible models that can be fitting for identifying and interpreting weak signals of change. It further discusses the current implications of AI for foresight and possible future implications of its development (“explainable AI” and human-machine collaboration).

Originality/value
The paper hypothesizes on the emerging challenges in the field of collective intelligence for weak signals of change and suggests a new framework for mapping the field. The paper has not been published before.
Testing the mediation effects of contingent factors on the relationship between management control systems and performance in higher education institutions
Authors: Sofyani Hafiez , Sholihin Mahfud , Saleh Zakiah , Isa Che Ruhana 
Published: January 2025

Purpose
This study examines the mediating role of three psychological contingent factors: collegiality, creativity, and job satisfaction, on the relationship between management control system (MCS) implementation and performance of study programs in higher education institutions (HEIs). This study also examines the impact of contingent factors from organizational aspects such as HEI types, lecturer’s age, experience and qualifications.

Design/methodology/approach
This study uses a survey method with 581 permanent lecturers who were subjected to MCS at HIEs as respondents. A partial least squares structural equation modeling (PLS-SEM) approach, with mediation analysis, is used to test the proposed hypotheses.

Findings
The results show that the implementation of MCSs, in both public and private HEIs, from the output and behavioral control dimensions is positively associated with the performance of the study programs, but input control is not. Additionally, creativity and job satisfaction are positively associated with the performance of the study programs, but not for collegiality. From the mediation analyses, creativity and job satisfaction mediate the relationship of all dimensions of MCS in relation to performance, except for one, namely, creativity does not mediate the relationship between behavioral control and performance. The analysis, however, reveals that collegiality does not mediate the relationship between all MCS dimensions and performance. The results of the multigroup analysis on different HEI types (public vs private) and demographic factors are discussed further.

Practical implications
The study’s findings offer valuable guidance for authorities on designing MCS models to enhance HEI study program performance. It highlights seven key contingent factors to consider: collegiality, creativity, job satisfaction, HEI type, age, experience and educational qualifications.

Originality/value
This study addresses the research gap related to the design of MCS in HEIs, and the inconsistencies of their role in performance by examining the influence of seven contingent factors addressed in prior literature. By so doing, this study provides new insights into the impact of collegiality, creativity, job satisfaction, different HEIs types (public vs private), age, experience and educational qualifications on the relationship between MCS implementation and performance of HEIs.
Modeling enablers of logistics outsourcing adoption: a case of manufacturing industry
Authors: Alsmairart Mohammad A.K. 
Published: January 2025

PurposeInnovation capabilities, changes in customer expectations and continuous supply chain (SC) network disruptions bring complexity and challenges to manufacturing firms (MFs). This study examines the influence of uncertainty, supplier innovation, cost reduction and integration of third-party logistics (3PLs) and fourth-party logistics (4PLs) on logistics outsourcing adoption.Design/methodology/approachBased on data collected from 180 managers in MFs in Jordan, our proposed research model was tested using partial least squares-SEM (PLS-SEM).FindingsThe findings suggest that supplier innovation and integration with 3PLs and 4PLs are key enablers of adopting logistics outsourcing in the manufacturing sector. Further, the findings indicate no significant impact of uncertainty and cost reduction as logistics outsourcing enablers. The results also suggest that integration with 3PLs and 4PLs mediate fully and positively the path between supplier innovation and logistics outsourcing adoption.Originality/valueThis study contributes to the manufacturing literature by providing a better understanding of the main enablers of logistics outsourcing in the manufacturing sector, simultaneously tackling dependence and enhancing adoption performance in the innovation and disruptions SC era. Further, it expands the understanding of the integration between SC partners in these twofold roles.
Role of governance in place making in intergenerational living and learning campuses for seniors and teenagers
Authors: Narula Nehchal Kaur , Pancholi Surabhi , Kreutz Angela , Sanders Paul 
Published: January 2025

Purpose
This study aims to elucidate the role of governance in design, development and sustenance of intergenerational living and learning campuses for seniors and teenagers and identifying the considerations, barriers and opportunities for place making in such shared campuses.

Design/methodology/approach
A single-case study approach based on semi-structured interviews using photo-elicitation and on-site observations was undertaken at the co-located campus of an aged care facility and school in Australia. The data was analysed through inductive-deductive content analysis using the lens of a pre-conceived place making framework.

Findings
Strong and adaptive governance on an organizational level is important for the design, development and sustenance of intergenerational living and learning campuses to overcome the multi-faceted barriers posed by the community and segregation between the aged care and education sectors. There is a need for co-locating organizations to mesh the intergenerational vision with their individual policies and goals using a spatio-environmental, psychological, socio-cultural, organisational and politico-economic lens on a micro, meso and macro scale.

Originality/value
This research contributes to the emerging literature on intergenerational living and learning campuses for seniors and teenagers using the lens of place and place making, particularly in the Australian context where intergenerational programmes are still in their infancy.
Dynamic managerial capabilities and organizational change capacity as precursors of organizational dynamic capabilities in SMEs
Authors: de Abreu Saraiva Monteiro Alves André , Manuel Pereira de Oliveira Carvalho Fernando 
Published: January 2025

PurposeWhile organizational dynamic capabilities (DCs) are understood as crucial to small- and medium-sized enterprises (SMEs)’ success, the configurations of individual-level capabilities and meta-capabilities, in the form of dynamic managerial capabilities (DMCs) and organizational change capacity (OCC), in which that outcome can be observed are not clear. We answer this research question while considering the firm’s internationalization as a moderator.Design/methodology/approachWe conduct a two-stage fsQCA analysis, with data obtained through a questionnaire.FindingsOur results indicate two equifinal main paths. Managerial cognition of DMCs and the change processes capacity of OCC are incredibly relevant conditions for determining the outcome of DCs in SMEs, with a peripheral role of the remaining OCC dimensions. Internationalization moderates this relationship. In internationalized firms, as the second path, organizational learning, the capability to change contexts and human capital gain prominence.Research limitations/implicationsWe offer important insights into the contingencies of the development of DCs in SMEs, highlighting the importance of configurational thinking. More than one or other related dimension, the conjunction of DMCs’ and OCC’s dimensions determines the presence of DCs. Furthermore, we highlight the importance of considering the internationalization of the firm.Originality/valueNo study has approached DMCs and OCC as capability antecedents of DCs in SMEs, disentangling interrelated antecedents and thus determining the sufficient conditions for their formation. The consideration of the moderation of internationalization further expands the contextual relevancy of these antecedents. Methodologically, we are one of the first studies to utilize newly improved procedures to study moderation in a configurational analysis.
A consumer acceptance model in the artificial intelligence era
Authors: Pramanik Paritosh , Jana Rabin K. 
Published: January 2025

PurposeThis paper identifies consumer acceptance criteria of artificial intelligence (AI)-enabled products and services in the business. We first investigate the existing three models. They are the technology acceptance model (TAM), the unified theory of acceptance and use of technology (UTAUT) and the consumer acceptance of technology (CAT). We then discuss the applicability of these three models for AI-enabled products and services. Finally, we outline the shortcomings of the models and propose an AI-enabled product and service acceptance model (AIEPSAM). We also validate the proposed AIEPSAM model with empirical results using primary survey data.Design/methodology/approachTo understand the customer’s point of view on AI applications in products and services, we identify some critical factors and present a conceptual framework of consumers' acceptance criteria based on existing literature, prior research and prominent technology management theories. Then, the study broadens the horizon beyond established principles associated with technology acceptance to accommodate AI-specific factors/variables like data privacy, explainability and apparent opacity of algorithms. In this paper, we propose an AIEPSAM and validate that model with primary survey data.FindingsWe argue that although TAM, UTAUT and CAT models are generally applicable to explain consumers' attitudes towards technology, these models alone are insufficient to encompass the entire spectrum of AI-related issues that must not be ignored. The proposed model, namely AIEPSAM, accommodates the limitations of the existing models and modifies the CAT model to make it suitable for the acceptance of AI technology.Originality/valueWe attempt to articulate the consumer acceptance criteria of AI-enabled products and services and discover useful insights, leading to the critical examination of TAM, UTAUT and CAT models and formulating AIEPSAM with validation through primary survey data. This study is not to criticize the TAM and other technology acceptance models but to incorporate AI-specific factors into those models. Through this study, we propose the required modifications in the existing technology acceptance models considering the AI-specific additional factors. The AIEPSAM will assist companies in building AI-enabled products and services and better understanding the technology emergence (TE) and technology opportunities (TO).
New Strains of the Deep Branching Streptophyte Streptofilum: Phylogenetic Position, Cell Biological and Ecophysiological Traits, and Description of Streptofilum arcticumsp. nov
Authors: Glaser Karin , Mikhailyuk Tatiana , Permann Charlotte , Holzinger Andreas , Karsten Ulf 
Published: January 2025

ABSTRACTStreptofilum capillatum was recently described and immediately caught scientific attention, because it forms a phylogenetically deep branch in the streptophytes and is characterised by a unique cell coverage composed of piliform scales. Its phylogenetic position and taxonomic rank are still controversial discussed. In the present study, we isolated further strains of Streptofilum from biocrusts in sand dunes and Arctic tundra soil. Molecular and morphological characterisation including transmission electron microscopy confirmed that both new strains belong to Streptofilum. The Arctic strain is described as a new species, Streptofilum arcticum sp. nov., based on molecular differences, a specific sarcinoid morphology and unique ultrastructure with massive cell coverage composed of pili‐shaped scales. A comprehensive characterisation of the ecophysiological traits of both new Streptofilum isolates and the original one revealed a broad temperature tolerance, a rapid recovery of photosynthetic performance after desiccation, an efficient photosynthesis at low light and a tolerance to high‐light conditions. In addition, Streptofilum could cope with UV irradiation, but only S. capillatum grew under UV exposure. All Streptofilum strains are well‐adapted to water‐deprived terrestrial habitats such as biocrusts. From this study it can be concluded that already early‐branching streptophytes were able to tolerate terrestrial conditions.
