Published: June 2024

AbstractChanges in cell state are often accompanied by altered metabolic demands, and homeostasis depends on cells adapting to their changing needs. One major cell state change is senescence, which is associated with dramatic changes in cell metabolism, including increases in lipid metabolism, but how cells accommodate such alterations is poorly understood. Here, we show that the transcription factor p53 enables recycling of the lipid headgroups required to meet the increased demand for membrane phospholipids during senescence. p53 activation increases supply of phosphoethanolamine (PEtn), an intermediate in the Kennedy pathway forde novosynthesis of phosphatidylethanolamine (PE), by transactivating genes involved in autophagy and lysosomal catabolism that enable membrane turnover. Disruption of PEtn conversion to PE is well-tolerated in the absence of p53 but results in dramatic organelle remodeling and perturbs growth and gene expression following p53 activation. Consistently, CRISPR-Cas9-based genetic screens reveal that p53-activated cells preferentially depend on genes involved in lipid metabolism. Together, these results reveal lipid headgroup recycling to be a homeostatic function of p53 that confers a cell-state specific metabolic vulnerability.
Correlated frequency noise in a multimode acoustic resonator
Authors: Tubsrinuan Nuttamas , Cole Jared H. , Delsing Per , Andersson Gustav 
Published: June 2024

Frequency instabilities are a major source of errors in quantum devices. This Letter investigates frequency fluctuations in a surface acoustic wave (SAW) resonator, where reflection coefficients of 14 SAW modes are measured simultaneously for more than 7 h. We report two distinct noise characteristics. Multimode frequency noise caused by interactions with two-level system (TLS) defects shows significant degrees of correlation that diminish with increased detuning. This finding agrees with the current understanding of the parasitic TLS behavior as one of the dominant noise sources in quantum devices. In addition to the TLS-induced noise, we observe strong anomalous frequency fluctuations with slow, anticorrelated dynamics. These noise bursts resemble signatures of cosmic radiation observed in superconducting quantum systems.

Poles and poltergeists in
e+e−→DD¯
data
Authors: Hüsken Nils , Lebed Richard F. , Mitchell Ryan E. , Swanson Eric S. , Wang Ya-Qian , Yuan Chang-Zheng 
Published: June 2024

A recent report of e+e−→DD¯ events by the BESIII collaboration suggests the presence of a structure R at 3900 MeV. We argue that this structure, called G(3900) in the past, is not in fact due to a new cc¯ resonance but rather naturally emerges due to a combination of interference between nearby resonances and the opening of the D*D¯ channel. We further find that the appearance of this structure does not require suppression because of a radial node in the ψ(4040) wave function, although a node improves fit quality. The measured e+e− coupling of ψ(4040) is found to be substantially smaller than previously estimated. In addition, we report new corrections to the measured cross section σ(e+e−→DD¯) at energies near ψ(3770).

Authors: Tabassum Marya , Raziq Muhammad Mustafa , Allen Matthew , Sarwar Naukhez , Golra Owais Anwar 
Published: June 2024

PurposeLeadership research has traditionally focused on formal leadership; however, leaders may emerge in informal settings in self-managed teams, and little is known about who emergent leaders are and what their characteristics are. This study investigates emergent leaders' behaviors, roles, skills, and leadership style, drawing on a multi-method approach.Design/methodology/approachWe first identify emergent leaders using social network analysis and aggregation approaches. Second, we investigate emergent leaders' characteristics using interviews with forty agile team members in five organizations.FindingsResults indicate different roles of emergent leaders (i.e. coach, liaisons), leadership styles (i.e. supportive), skills (i.e. culturally intelligent, strategist), and influencing factors (i.e. personality, technical knowledge, social circle).Originality/valueWe contribute by identifying emergent leaders through multiple identification methods (i.e. network analysis, aggregation), and then through identifying their various characteristics, we contribute to leadership literature as well as idiosyncrasy-credit theory. We also add to agile-leadership theory, showing that multiple informal leaders may emerge within agile teams. Finally, our findings have practical implications for self-managed teams, informal group settings, organizational change professionals, and organizations with horizontal structures.

An implicit solution method for digital construction of temperature fields in concrete structures based on point temperature measurements
Authors: Zhu Zhenyang , Liu Yi , Zhang Lei 
Published: June 2024

PurposeAt present, using the finite element method is difficult to efficiently and accurately construct the temperature field of mass concrete based on temperature measurement points. Thus, there is a need to propose a method for improvement.Design/methodology/approachThis study developed an implicit finite element method that digitally constructs the temperature field of mass concrete based on temperature measurement data. That is, in the proposed method of this paper, the temperature of the measuring point is also one of the boundary conditions, which real-time corrects the calculation error.FindingsIn this method, during the digital construction of the temperature field, the computed temperature approaches the actual measured value at the point of measurement with increasing iteration steps. Using this method and sufficient temperature measurement data, the errors in calculation conditions (such as the boundary conditions, the initial casting temperature and material parameters) can be automatically corrected during the iterative computation process.Originality/valueThis new method can improve calculation accuracy and allows the digitally constructed temperature field to converge to its true value with sufficient measurement data.

Authors: Gasue Rhoda , Aklashie Samuel , Dompey Annabel Morkporkpor Ami , Agyekum Kofi , Opoku Desmond 
Published: June 2024

PurposeThe increasing concern for waste reduction in the global construction industry has led to diverse sustainable approaches emerging globally in the past decade. Material passport (MP), a growing approach, has been seen to be very promising. This study examines the implementation of materials passports in the Ghanaian construction industry.Design/methodology/approachThe study adopted the quantitative research method. Having reviewed literature related to this study, questionnaires served as a means of soliciting the views of 77 professionals in the built environment in the Ghanaian construction industry on the theme under investigation. Descriptive and inferential statistical analyses were used to analyze the data retrieved.FindingsFindings from the study revealed that Ghanaian construction professionals possessed a low level of awareness of the concept of MPs. However, they showed a massive willingness to adopt MPs in their professional practice. The findings further revealed that the professionals believed challenges such as the lack of knowledge, complexities of MP in terms of its preparation, and lack of quality assurance for recovered products hinder the adoption of MPs. The findings also revealed that strategies such as adequate training and education, policies and regulations, and adequate stakeholder engagement could aid in the implementation of MPs in the Ghanaian construction industry.Originality/valueFor the concept of MPs to gain a firm foundation globally, its perception and implementation must be explored thoroughly. This empirical study, being the first to investigate MP implementation in Ghana, has provided insights into the topic from the perspective of professionals operating in the Ghanaian construction industry. The paper reveals information on the practice of MPs from the context of a typical developing country.
Disentangling the effects of entrepreneurs’ passion and perfectionism on their eudaimonic well-being
Authors: Luu Ngoc , Nguyen Huy 
Published: June 2024

PurposeReflecting subjective feelings of aliveness, thrivingness and energy, entrepreneurs’ eudaimonic well-being helps to enhance firm performance, which raises the question how to improve this largely under-researched type of well-being. Drawing upon the conservation of resources theory, this study examines how an entrepreneur’s obsessive passion has an inverted U-shaped association while harmonious has a positive association with their eudaimonic well-being, and how these relationships vary under the moderating effect of socially prescribed perfectionism.Design/methodology/approachStudy 1 includes a survey with entrepreneurs from 182 small businesses in Vietnam. To overcome the limitation of cross-sectional data in Study 1 and test the hypotheses in a diverse and western sample, this research employed a two-wave lagged design in Study 2 with 81 entrepreneurs in the United States and United Kingdom.FindingsBoth studies confirmed that an entrepreneur’s harmonious passion has a positive association and obsessive passion has an inverted U-shaped association with their eudaimonic well-being. This study also found these associations are moderated by socially prescribed perfectionism.Originality/valueThis research extends the literature on eudaimonic well-being in entrepreneurship by confirming its determinants and contributes to the debate about the positive side of obsessive passion. Also, its examination of socially prescribed perfectionism in the context of entrepreneurship lays the foundation for further research on the role of this important personality trait in shaping the performance and well-being of entrepreneurs. This study provides theoretical contributions and managerial implications and suggests areas for future research.
Linear recruitment in tourism academia: when academic jobs “go sideways”
Authors: Seraphin Hugues , Smith Simon , Wyatt Brianna , Kozak Metin , Kennell James , Mandić Ante 
Published: June 2024

Purpose
The recruitment and promotion of teaching academics in the UK is constrained by a complex array of career progression barriers. These barriers have led to an increasing trend of horizontal career (lack of) progression. The purpose of this paper is to reveal and discuss linearity and horizontality constrictions, challenges and issues impacting on potential careers in tourism academia.

Design/methodology/approach
This study uses a leading UK national academic recruitment website to gather data and insights from across 137 posted jobs related to tourism between 2020 and 2022.

Findings
The main findings of this work note the constrictions of the UK academic job market and the consequences it poses for academics within tourism and beyond. It is proposed that future research to further understand the realities faced by academics is needed to prompt action for change to create more enriching career development.

Originality/value
The contribution of this study centres around sense making a phenomenon that exists but is not often talked about within academia (whether in tourism or beyond). For academics and managers, this paper presents an opportunity to reflect more holistically on careers with a view to instigating valuable change moving forward (for oneself or others). There is also a dearth of studies relating to career progression of tourism higher education educators.
Understanding the role of organizational design in fostering long-term dynamic capabilities: a longitudinal case study
Authors: Bojesson Catarina 
Published: June 2024

Purpose
Organizational design has been suggested as a facilitator of an organization’s dynamic capabilities. This study aims to investigate the role of organizational design in the concept of dynamic capabilities and explores how it facilitates long-term dynamic capabilities in practice.

Design/methodology/approach
Empirical data were collected via a longitudinal case study conducted at a global company engaged in the development and manufacture of railway equipment. Specifically, this study focused on one of the organization’s sites in Sweden for a period of approximately five years.

Findings
Organizational design has a twofold impact on dynamic capabilities, functioning as both a facilitator and an impediment. It is essential for structures and processes to align with the available resources and capabilities of an organization. Moreover, managers’ beliefs and decision making significantly influence the extent to which organizational design choices effectively foster dynamic organizational performance.

Originality/value
This longitudinal case study contributes to the theory of dynamic capabilities by identifying key changes in an organization that is transforming to become more dynamic and the impact of organizational design on the organization’s dynamic capabilities.
Decoding workplace dynamics: unveiling perceptual and attitudinal drivers of counterproductive work behaviour using hybridSEMANN approach
Authors: Abdullah Hasan Oudah , Al-Abrrow Hadi 
Published: June 2024

Purpose
The study aims to determine the impact of perceptual and attitudinal factors on employees’ counterproductive work behaviour (CWB). The study emphasises the verification of the direct, indirect, linear and non-linear effects of several antecedents of CWBs. The moderating role of self-efficacy is also investigated.

Design/methodology/approach
Data were collected from 1,215 employees from several industrial companies in Southern Iraq. The study used the hybrid approach to data analysis, based on a dual-stage SEM-ANN, i.e. partial least squares structural equation modelling and artificial neural network approach.

Findings
Results indicate that most of the proposed variables predict CWB and that abusive supervision and perceived organisational politics (POP) positively affect job burnout (JB) through job stress. In addition, non-linear relationships, JB, abusive supervision and POP are the most important in predicting CWB. The study confirms that a negative perception of the work environment increases the likelihood of harmful behaviours in the organisation and that self-efficacy can reduce such a perception.

Originality/value
The importance of the current study is summarised in its attempt to verify the antecedents of CWB by relying on a two-step approach to test linear and non-linear relationships. This approach will greatly enhance theories regarding adverse behaviour in the workplace, especially, with a fairly large sample size.
