Published: January 2025

ABSTRACTThe nitrogenase gene cluster of unicellular diazotrophic cyanobacteria such asCyanotheceis frequently selected by nature for nitrogen fixing partnerships with eukaryotic phototrophs. The essential cluster components that confer an advantage in such partnerships remain under explored. To use this cluster for the development of synthetic, phototrophic nitrogen-fixing systems, a thorough and systematic analysis of its constituent genes is necessary. An initial effort to assess the possibility of engineering this cluster into non-diazotrophic phototrophs led to the generation of aSynechocystis6803 strain with significant nitrogenase activity. In the current study, a refactoring approach was taken to determine the dispensability of the non-structural genes in the cluster and to define a minimal gene set for constructing a functional nitrogenase for phototrophs. Using a bottom-up strategy, thenifgenes fromCyanothece51142 were re-organized to form new operons. The genes were then seamlessly removed to determine their essentiality in the nitrogen fixation process. We demonstrate that besides the structural genesnifHDK,nifBSUENPVZTXWas well ashesABare important for optimal nitrogenase function in a phototroph. We also show that optimal expression of these genes is crucial for efficient nitrogenase activity. Our findings provide a solid foundation for generating synthetic systems that will facilitate solar powered conversion of atmospheric nitrogen into nitrogen rich compounds, a stride towards a greener world.IMPORTANCEIntegrating nitrogen fixation genes into various photosynthetic organisms is an exciting strategy for converting atmospheric nitrogen into nitrogen rich products in a green and energy efficient way. In order to facilitate this process, it is essential that we understand the fundamentals of the functioning of a prokaryotic nitrogen fixing machinery in a non-diazotrophic, photoautotrophic cell. This study examines a nitrogenase gene cluster that has been naturally selected on multiple occasions for a nitrogen fixing partnership by eukaryotic photoautotrophs and provides a basic blueprint for designing a photosynthetic organism with nitrogen fixing ability.

Leveraging job rotation programs for experiential learning in organizations through the lens of Kolb’s experiential learning theory
Authors: Saikrishna M.B. 
Published: January 2025

Purpose
This research proposes a theoretical model that combines Kolb’s Experiential Learning Theory with organizational job rotation. This paper aims to develop a model that can improve the efficiency of job rotation as a tool for experiential learning and organizational development.

Design/methodology/approach
This paper integrates the literature on job rotation and Kolb’s Experiential Learning Theory. It provides theoretical propositions and a conceptual model for integrating job rotation into the four stages of Kolb’s learning model.

Findings
The paper offers a set of propositions that states that job rotation programs that are in sync with Kolb’s learning cycle will foster better learning results, more cross-functional knowledge, increased employee flexibility, and better organizational performance. The conceptual framework helps outline the best ways of designing and implementing job rotation programs so that learning by experience is enhanced.

Research limitations/implications
Future research should empirically validate its propositions. Qualitative studies, such as interviews with HR practitioners, can explore practical applications of the framework. Longitudinal studies can assess the long-term impact of Kolb-aligned job rotation programs on employee performance and organizational outcomes. Additionally, cross-cultural and comparative research could identify moderating factors, such as industry-specific or cultural influences.

Practical implications
Job rotation programs should integrate all four stages of Kolb’s learning cycle, with challenging tasks fostering Concrete Experience (CE), structured reflection sessions supporting Reflective Observation (RO), workshops linking experiences with organizational theories for Abstract Conceptualization (AC), and leadership roles or process improvements providing opportunities for Active Experimentation (AE). Additionally, organizations should establish systems to measure the effectiveness of job rotation programs, such as pre- and post-rotation surveys, tracking career development, and evaluating the program’s impact on organizational performance, including creativity and innovation.

Originality/value
This study contributes to the literature by developing a theoretical model of Kolb’s Experiential Learning Theory and job rotation practices to help organizations improve their learning from job rotation. It can be helpful for scholars and practitioners in the field of organizational development as it connects the theory and practice of education.
Design team effectiveness and architects’ personality types
Authors: Alan Ece , Arditi David , Gunaydin Husnu Murat , Akcay Emre Caner 
Published: January 2025

PurposeThe personalities of the design team members constitute one of the factors that influence team effectiveness. In this study, 223 members of the “American Institute of Architects” who are employed by the largest architectural design firms in the United States of America were categorized according to their personality types by using “The Enneagram Personality Type Model.” Also, the respondents’ opinions about eight team effectiveness outcomes were recorded in order to explore the relationship between team members’ personality types and team effectiveness outcomes.Design/methodology/approachThe information was collected by a questionnaire where the first part included 144 pairs of statements that were used to identify respondents’ personality types. The second part sought designers’ opinions about the importance of eight team effectiveness outcomes rated on a Likert scale ranging from 1 to 5. The results were assessed by performing the Kruskal–Wallis test first and Dunn’s post-hoc test with Bonferroni adjustment subsequently.FindingsThe findings highlight the significance of personality types in effective design teams. While Type 6 (loyalist and skeptic) and Type 3 (achiever and performer) architects prioritize team effectiveness the most, Type 7 architects (enthusiasts and epicureans) assign the lowest importance. However, the presence of Type 1 (reformist and perfectionist) and Type 8 (challenger and protector) architects within the same design team may involve challenges or conflicts.Originality/valueThe primary contribution of this study is that it is the first study in the construction management literature that utilizes The Enneagram of Personality Test to understand the relationship between team members’ personality types and team effectiveness outcomes. This study is of direct relevance to practitioners and could be utilized in design team-building activities.

Purpose
This study aims to explore the concept of collaborative consumption (CC) by identifying factors that drive and deter individual participation in CC. The concept of CC encompasses practices such as sharing, giving, renting, donating, swapping and trading pre-owned goods with another individual, all of which reduce new purchases and promote the reuse of goods, thereby protecting resource depletion and waste.

Design/methodology/approach
Using a qualitative research approach, a total of 23 semi-structured, in-depth interviews were conducted with the participants involved in various shared consumption activities. The thematic analysis was done on interview data to explore the themes and subthemes of CC in the form of drivers and deterrents.

Findings
The findings reveal economic, social connection, sustainability, ease of use, utilization of goods and surroundings as driving factors of CC. Moreover, security concerns, lack of awareness and lack of accessibility were explored as deterring factors. Based on the findings, the present study proposes a conceptual framework for future studies.

Originality/value
The study adds value to the understanding of CC, which is in a nascent stage. The unique drivers and deterrents of CC, as explored in the present study, have significant implications for marketers, business developers, researchers and practitioners.

How subsidiaries contribute to MNC’s resilience under global disruptions
Authors: Asakawa Kazuhiro , Aliasghar Omid , Un C. Annique 
Published: January 2025

Purpose
This paper explores how the organizational resilience of multinational corporations (MNCs) can be attained through mitigating the liability of foreignness (LOF) faced by their subsidiaries so that they can navigate challenges more effectively. By bridging the gap between MNC resilience and the liability and advantage of foreignness of their subsidiaries, this study aims to provide a comprehensive understanding of how MNCs can thrive in volatile and uncertain international markets.

Design/methodology/approach
By drawing on the extant literature on resilience and liability/advantage of foreignness, this paper presents a novel perspective on the way resilience of subsidiaries contributes to the resilience of the MNCs as a whole.

Findings
Subsidiaries contribute substantially to the resilience of MNCs by creating a network of adaptive responses in their host locations and beyond and by playing crucial roles in challenging uncertain and turbulent environments. Accordingly, the resilience of foreign subsidiaries depends on their organizational capability and certain structural arrangements that enable them to turn LOF into advantage. This intricate interplay emphasizes the importance of subsidiary-level resilience in shaping the resilience of the entire MNC.

Originality/value
This paper emphasizes the importance of paying attention to the resilience of the whole MNC while stressing the important role played by the subsidiaries to turn the LOF into the advantage.
Divided We Stand: Top Management Ideological Separation as an Impediment to Strategic Change in Turnaround Situations
Authors: Georgakakis Dimitrios , Ma Yao , Dwivedi Priyanka , Cannella Albert A. 
Published: January 2025

AbstractIntegrating the diversity‐as‐separation perspective with the uncertainty‐threat principle from the field of political psychology, we introduce the notion of ideological separation in top management teams (TMTs) and examine its effects on strategic change in an uncertainty‐threat context that requires executives’ adaptive action (i.e. turnaround situations). We argue that, in turnaround situations, differences in values (i.e. political ideology) between executives activate ideological separation in the TMT, which causes decision paralysis in the executive group and lessens its ability to enact strategic change. Our research also considers the contingent role of two external environmental factors that may heighten uncertainty‐threat for executives in turnaround situations and strengthen the hypothesized main effect – that is, shareholder unrest (i.e. the degree to which shareholders submit complaints against corporate leadership and proposals for remedy) and industry performance decline (i.e. the degree to which the turnaround firm's industry experiences declining performance). Data from S&P 1500 firms show that TMT ideological separation inhibits strategic change in turnaround situations. They also highlight the dark side of shareholder democracy, by showing that – in turnaround contexts – shareholder unrest intensifies this relationship. Implications for upper echelons, strategic management, TMT diversity, political ideology and turnaround research are discussed.
Hierarchical Political Power and the Value of Cash Holdings
Authors: Liu Jia , Talavera Oleksandr , Yin Shuxing , Zhang Mao 
Published: January 2025

AbstractThis study examines the relationship between hierarchical political power and the value of cash holdings. To model the power structure, we utilize the hierarchical civil service system in China to distinguish between the holders of high‐ and low‐level political power. We establish that directors with high‐level political power increase the market value of cash, whereas those with low‐level political power have no impact. Such effects are more pronounced in non‐state‐owned firms, in regions where politicians are subject to higher political pressure and in firms experiencing stronger agency conflicts. Further analysis shows that directors with high‐level political power can increase the value of cash holdings through improved investment efficiency. Among directors with high‐level political power, shareholders benefit most from the presence of those ranked at the Bureau‐Department level. Our study provides original evidence that political hierarchy holds significance for investors’ valuation of cash holdings and emphasizes the importance of the heterogeneous nature of boards’ political capital in determining corporate value.
Investigating potential tactile strategies of students with deafblindness: An exploratory study
Authors: Papazafiri Maria , Argyropoulos Vassilios 
Published: January 2025

AbstractThe purpose of this study was to investigate and describe tactile exploratory behaviours and strategies applied by students with deafblindness when they actively explore objects by touch in terms of their texture and weight. For the needs of the present study, a Delphi consultation methodology was applied by the authors and special education teachers. The students were invited to participate in matching activities with familiar objects focusing on texture and weight, respectively. The analysis revealed that the students adopted a combination of tactile exploratory behaviours and strategies in order to identify an object's texture and weight. It seemed that the tactile exploratory strategy ‘Pressure’ in combination with a variety of tactile behaviours such as banging, shaking or/and rotating was in common. The results may contribute to the formation of more sophisticated individualized educational plans giving emphasis on active touch. Tactile exploratory strategies procedures are considered to be of high importance for students with deafblindness since they constitute ‘roadmaps’ for them to build‐up their knowledge following a ‘kinesthetic reasoning’.
Ethical issues in special needs educators' consultation: Examples from the Swedish context
Authors: Hansson Susanne , Lindblom Anne 
Published: January 2025

AbstractThe purpose of this study is to produce new insights of ethical issues in special needs educators' (SNEs) consultation with teachers in Swedish schools, by using the theoretical lens of Løgstrup's (1997) theory the Ethical Demand. The research questions concern (1) how the SNEs describe the content of their consultation and (2) how the SNEs describe how they deal with resistance to consultation. Semi‐structured interviews with eight SNEs were analysed by using the theory of The Ethical Demand by Løgstrup. Main results are that consultation is viewed as widening the thinking of the teachers and resistance is dealt with by SNEs avoiding undesired consultation. Resistance to consultation is regarded as a way for teachers to maintain their integrity when being forced to consultation. The study reveals that ethical issues are deeply integrated in consultation and the use of the theory of the Ethical Demand sheds new light on the ethical‐philosophical grounds in SNEs' consultation practice.
Origins of T‐cell‐mediated autoimmunity in acquired aplastic anaemia
Authors: Enache Aura , Carty Shannon A. , Babushok Daria V. 
Published: January 2025

SummaryAcquired aplastic anaemia (AA) is an autoimmune bone marrow failure disease resulting from a cytotoxic T‐cell‐mediated attack on haematopoietic stem and progenitor cells (HSPCs). Despite significant progress in understanding the T‐cell repertoire alterations in AA, identifying specific pathogenic T cells in AA patients has remained elusive, primarily due to the unknown antigenic targets of the autoimmune attack. In this review, we will synthesize findings from several decades of research to critically evaluate the current knowledge on T‐cell repertoires in AA. We will highlight new insights gained from recent in vitro studies of candidate autoreactive T cells isolated from AA patients and will discuss efforts to identify shared T‐cell clonotypes in AA. Finally, we will discuss emerging evidence on the potential T‐cell cross‐reactivity between HSPC and common viral epitopes that may contribute to the development of AA in some patients. We conclude by highlighting the areas of consensus and limitations, as well as the ongoing uncertainties, and we identify promising directions for future research in the field.
