First-order perturbative estimate of the
d+t+γ→α+n
reaction rate
Authors: Timofeyuk N. K. 
Published: December 2024

A new type of photoinduced nuclear reactions is considered when a photon is absorbed by a continuum state and accompanied by nuclear rearrangement. An important example of such reactions is d+t+γ→α+n which, in the regions of space containing a hot d−t mixture and a very large number of low-energy photons, can dominate the d+t→α+n fusion reaction, leading to an additional high-energy release. The present estimates of the environmental conditions where this might happen are made based on first-order perturbation theory with several values of the infrared cutoff. It is shown that with a cutoff of 1 eV, which corresponds to infrared light, the photon capture is several times larger than the d−t fusion rate in the big bang nucleosynthesis in the early universe, makes a noticeable contribution to energy release in tokamaks, and dominates by a few orders of magnitude in laser-direct-driven inertial confinement fusion. No effect on these three environments can be seen if the infrared cutoff is 1 keV. However, with this cutoff the photon absorption in a d−t mixture could become noticeable in future laser facilities at power intensities above 1018Watt/cm2. With further increase of the intensity towards 1027Watt/cm2 photon capture will dominate even if the first-order perturbation theory breaks down at very large values of the infrared cutoff, around 1 MeV. The development of a nonperturbative approach to d+t+γ→α+n reaction is crucial to capture correctly the physics of low-energy photoabsorption with high-energy release.

Navigating the innovation dilemma: the paradox of leader’s self-confidence in conflict management
Authors: Dhillon Padmavathy , Srivastava Bharatendu Nath , Joshi Chetan 
Published: December 2024

Purpose
This study aims to investigate the circumstances where the positive influences of leader’s self-confidence are weakened in situations of conflict management (CM) arising due to innovation implementation. Specifically, this study tests the moderating influence of financial slack, internal opposition posturing and performance feedback on the relationship between self-confidence and conflict management styles (CMS). The findings are not complete.

Design/methodology/approach
This experimental study was conducted in two stages: In Stage 1, the authors studied moderating effects of financial slack (sound/unsound) and internal opposition posture (encouraging/ discouraging) on the relationship between leader’s self-confidence and CMS, namely, dominating, integrating and avoiding. In Stage 2, the authors studied the moderating effect of performance feedback (success/failure) on the relationship between leader’s self-confidence and three CMS. Data were collected from 268 senior-level Indian managers in Stage 1, out of which 235 managers also responded in Stage 2. These participants assumed the positions of chief executive officers (CEOs) within major Indian manufacturer specializing in electrical components, enabling us to empirically test the proposed model. Furthermore, a qualitative analysis of 10 semistructured interviews with Indian CEOs were conducted to enrich the discussion of the results.

Findings
Leader’s self-confidence determined the three CMS with highly self-confident leaders displaying irrational behavior in persisting with innovation through dominating style. Internal opposition posture and performance feedback exerted main effects on dominating style.

Research limitations/implications
This study supports behavioral decision theory of firm and escalation of commitment theory.

Practical implications
This study underscores the need for personality and self-awareness training amongst senior managers to mitigate irrational behavior due to excessive self-confidence and enhanced effective CM.

Originality/value
This study identifies a crucial boundary condition where high self-confidence in innovation implementation may lead to irrational behavior and ineffective CM.
Perceived performance in coworking spaces: the effect of face-to-face and online social interactions
Authors: Labrado-Antolín Maribel , Delgado-Piña Isabel , Fernández-Menández José , Rodríguez-Ruiz Óscar 
Published: December 2024

Purpose
This paper aims to explore the impact of face-to-face and online social interactions on coworkers’ perception of performance in coworking spaces (CWS) compared to working from home (WFH). CWS are work environments where different actors compete and collaborate. The impact of such interactions on performance remains unclear. Building on the conceptual framework of “coopetition” (Bengtsson et al., 2016) and the theory of hyperpersonal interactions (Walther, 1996), this research attempts to bring light into the discussion.

Design/methodology/approach
The study hypothesizes that frequent face-to-face community events negatively affect coworker performance compared to WFH. Conversely, digital platforms connecting CWS users are expected to enhance performance. The authors use a data set of 135 CWS users. Linear regression models are fitted using self-rated performance in the CWS compared to performance when WFH as dependent variable.

Findings
This study’s analysis shows that the frequency of face-to-face events is negatively associated with perceived performance at CWS compared to performance at WFH. Furthermore, CWS digital platforms do not show a significant relationship with performance in CWS compared to WFH.

Originality/value
This study adds to the literature on “coopetition” with specific reference to the case of CWS. It broadens the activity school perspective highlighting that coworking offline and online interactions have different performance implications. The paper also contributes to the theory of hyperpersonal interactions by studying the role of online communication. Findings help CWS managers to make informed decisions about the perceived outcomes of the services they provide. The analysis reveals the need to reconsider the frequency of face-to-face social events to avoid dysfunctional effects.
Assessing path accuracy in industrial robots via ballbar technology
Authors: Bilancia Pietro , Ferrarini Sergio , Berni Riccardo , Pellicciari Marcello 
Published: December 2024

Purpose
This paper aims to present a methodology for evaluating the path accuracy of industrial robots using the telescoping ballbar measurement technology. The goal is to improve accuracy assessments in precision-driven manufacturing processes.

Design/methodology/approach
A single telescoping ballbar is used to assess the circle contouring performance of a KUKA KR210 R2700 prime robot. Experiments involve system setup, data collection and analysis in Matlab to derive performance metrics such as radial deviation, circularity and path accuracy error. This study investigates the impact of varying the operational conditions, including speed, payload and robot configuration, on these indexes through statistical analysis, and examines the relationship between joint errors and path deviations.

Findings
The results indicate that the robot behavior is influenced by the operating conditions, with notable error spikes at joint reversal positions due to factors such as joint backlash and transmission errors. This study evaluates various performance indexes from different standards, ISO 230 and ISO 9283, and identifies key operating parameters influencing each index. The findings suggest effective strategies for error compensation and performance enhancement.

Originality/value
This paper offers a novel approach to path accuracy verification and error source identification in industrial robots. It proposes methods to rapidly assess the correlation between performance and operating conditions, offering insights for better calibration and control strategies, especially in high-precision tasks.
The capacity of the halal brand logo to fortify the brand commitment of Muslim travellers
Authors: Mursid Ali , Pujiastuti Yanti , Rinwantin Rinwantin , Wibowo Radna Andi 
Published: December 2024

Purpose
The diverse impacts of brand logos on customer behaviour have garnered significant attention from scholars. However, the specific influences of halal brand logos remain mostly unexplored. This study aims to investigate the impact of halal brand logos on brand love, trust, self-brand connection and commitment.

Design/methodology/approach
This study used a survey to choose a sample of Indonesian Muslim customers who consumed halal brand foods, as indicated by the presence of the halal logo, throughout their travels in the years 2022–2023. The study was conducted using proportional random sampling among Muslim travellers in six provinces: Central Java, Yogyakarta, West Java, Jakarta, Banten and East Java. A total of 464 respondents participated in the poll. The analysis data used both confirmatory factor analysis and structural equation modelling.

Findings
The findings demonstrated a strong and statistically significant impact of the halal brand logo on both brand love and brand trust. Likewise, brand love and brand trust have a strong and meaningful impact on the emotional connection with the brand. Ultimately, emotional attachment and personal identification with a brand have a strong and meaningful impact on the level of commitment towards that brand. However, the level of trust in a brand does not have a major beneficial effect on brand commitment.

Practical implications
Clarifying the theory of customer–brand relationships, the results of this study suggest that halal food producers should pursue halal certification to succeed in their business, as the halal brand logo has a crucial effect on customers’ brand commitment. Halal food providers should immediately adopt the halal logo or certification to enhance customer brand love, trust, self-brand connection and commitment.

Originality/value
This study gives new insight to explain the effect of the halal brand logo on Muslim customer behaviour based on customer–brand relationships and thus contributes to the marketing literature.
Unraveling Dutch disease: remittances and exchange rate dynamics pre and post-GFC trends in 199 countries
Authors: Sadiq Ramla , Nosheen Safia , Yasser Farah 
Published: December 2024

PurposeThis study's main objective is to assess remittances' effect on real exchange rate movements pre- and post-GFC.Design/methodology/approachThe sample for this study includes 199 countries and independent territories for the period between 1999 and 2019. Furthermore, this period is divided into pre-GFC (inclusive) from 1999 to 2009 and post-GFC from 2010 to 2019. This paper uses a one-step GMM estimation on linear dynamic panel data.FindingsThe significant results from this study show that the exchange rate of remittances depreciates in every country, especially in low-middle-income countries. It has been found that, in high-income countries, the first lag of remittances has a significantly negative impact.Research limitations/implicationsThis study examines macroeconomic variables and remittance impacts, revealing clear trends in consumption patterns and exchange rates. Families use remittances for savings and investments, depreciating exchange rates. This suggests Dutch disease in economies, especially after GFC.Practical implicationsPolicy implications involve increasing exporter costs through variable taxes or retention, depreciating exchange rates and encouraging recovery from the Dutch disease. This promotes commodity trade and long-term economic benefits, while self-balancing protects against currency value depreciation.Originality/valueThis concepts originality lies in the focus on the impact of remittances on exchange rates and sectoral imbalances in various income-level countries over a significant period. The proposed policy implications aim to address the potential negative consequences of remittances on the economy, making it a valuable contribution to the existing research in this field.
Combination of KPIs and CEO’s messages: effective employee communication targeted at increasing the share of female managers
Authors: Kadomura Azusa , Sekiguchi Akiyuki , Kato Takumi 
Published: December 2024

Purpose
Corporate social responsibility (CSR) is a source of competitiveness that enhances a company’s reputation, promotes innovation and contributes to consumer purchasing behavior. Companies increase the number of women managers to strengthen CSR. However, the global average share of women managers is 28.2%, and in Japan, it remains low at 12.9%. One reason this situation has not improved is that existing research has focused on the effects and reasons for the share of female managers, and surprisingly, there is little knowledge about implementation. This study aims to fills that gap.

Design/methodology/approach
This study examines the research question, “Will adding a message from the CEO to a key performance indicator (KPI) that increases the share of female managers improve employee attitudes?” The authors conducted a randomized controlled trial in an online survey environment among 800 full-time employees of Panasonic Connect Co., Ltd. in Japan.

Findings
The result showed that simply presenting the KPI, “share of female managers,” was unlikely to impact employee attitudes positively. It was also desirable to convey the CEO’s message to customers.

Practical implications
Executives should adopt a corporate narrative strategy when communicating KPIs to their organizations. Adding the CEO’s words conveys the true meaning behind the numbers, elicits empathy and positively impacts employees’ attitudes.

Originality/value
To the best of authors’ knowledge, this study is the first to apply corporate narrative strategy findings to the effects of internal marketing on the share of female managers.

Advanced phasing techniques in congenital skin diseases
Authors: Natsuga Ken 
Published: December 2024

AbstractPhasing, the process of determining which alleles at different loci on homologous chromosomes belong together on the same chromosome, is crucial in the diagnosis and management of autosomal recessive diseases. Advances in long‐read sequencing technologies have significantly enhanced our ability to accurately determine haplotypes. This review discusses the application of low‐coverage long‐read sequencing, nanopore Cas9‐guided long‐read sequencing, and adaptive sampling in phasing, highlighting their utility in complex clinical scenarios. Through clinical vignettes, we explore the importance of phasing in gene therapy design for recessive dystrophic epidermolysis bullosa and the role of revertant mosaicism in therapeutic epidermal autografts. Despite its promise, phasing with long‐read sequencing faces challenges, including low efficiency in enriching target regions and the inherent error rate of nanopore sequencing. Future developments in long‐read sequencing technologies will be critical in overcoming these limitations and expanding the applicability of phasing across various clinical settings.
Diagnosing the Barriers Faced by Rural Communities in Building Disaster and Climate Resilience in Zimbabwe
Authors: Nyahunda Louis 
Published: December 2024

ABSTRACTThis study is poised to explore the barriers faced by rural communities in building disaster and climate resilience. The study was conducted against the backdrop that the frequency and intensity of climate change and its associated extreme weather events and hazards necessitate resilience building for at‐risk communities to protect the lives, livelihoods, economic, social and environmental assets. As rural communities endeavour to build resilience against climate change and disasters, they are confronted by a plethora of barriers that make disaster and climate resilience aspirations untenable. The study adopted the qualitative research approach within the exploratory research design. Community members, disaster risk reduction and climate change practitioners and traditional leaders were purposively sampled to share their insights on the subject matter. A total of 32 respondents participated in the study. Focus group discussions and semi‐structured interviews were used as data collection methods. Soaring poverty levels, weak and uncoordinated local institutions, recurring exposure to natural hazards and extreme weather events, limited community participation and inequalities emerged as barriers to disaster and climate resilience building in Zimbabwe's rural communities. The study provides nuanced empirical perspectives on barriers to disaster and climate resilience building to propose ways of dealing with them. The study sets pathways for policy reform at national and subnational levels and paradigm shifts where collective or individual efforts, changed ways of thinking, reprioritisation of resources, institutional support and political will can assist at‐risk communities overcome the identified barriers.

ABSTRACTObjectiveTo explore how women appreciated the risks discussed within the consent process for planned caesarean section (CS).DesignExploratory qualitative interview study.SettingNHS Teaching Hospital in Central London.PopulationWomen over the age of 18, English speaking, scheduled for a planned CS.MethodsSemi‐structured interviews were conducted before and after a woman's CS. Eighteen women were recruited and interviewed prior to undergoing CS and 12 of these were interviewed following CS. Interviews were audio‐recorded, transcribed and thematically analysed.Main Outcome MeasuresThemes generated from analysis of interviews exploring the experiences of women consenting to CS and specifically their awareness of postpartum haemorrhage (PPH), hysterectomy, organ damage and risk of placental abnormalities in future pregnancies.ResultsTwo broad themes and four subthemes were identified (1) Untimely provision of risk information: (a) superficial risk discussions during the antenatal period and full risk disclosure on the day of surgery and (b) incompleteness absent or sparse risk disclosure prior to making the decision to undergo the CS, where women were unaware of specific risks and (2) Emotional overload: (a) fear of risks and (b) fear that a CS will be denied to them—women's cognitive response and notably their emotional response to their situation limited their understanding of risks disclosed.ConclusionThe consent process for planned CS was found to lack appropriate and full risk disclosure. Risk disclosure was ill‐timed or deficient in facilitating women's understanding of risks reflecting a consent process which does not meet legal and professional standards of informed consent.
The effect of the EU's novel food regulations on firm investment decisions
Authors: Varacca Alessandro , Soregaroli Claudio , Kardung Maximilian , Espa Ilaria , Colombo Ilaria , Cortesi Beatrice , Wesseler Justus 
Published: December 2024

AbstractIn this study, we assess the effect of the European Union's novel food regulations on firms' incentives to invest in such products. We adopt a conceptual framework based on real option value theory, which underpins an empirical analysis of a detailed dataset comprising 326 applications submitted under both the 1997 EU novel food regulation and its 2018 replacement. We investigate the dynamics of novel food applications under these regulations and disentangle the determinants of successful cases. Our results show a relatively stable number of applications over the years, with a spike after the introduction of the 2018 regulation, which sought to simplify and centralise the approval process. This upsurge can be interpreted as a reduction in the real option value of postponing investments, attributable to the introduction of a transitional regime and of 5‐year data protection measures. However, the new regulation did not shorten the authorisation process, with the expected benefits of centralisation compromised by operational bottlenecks and a lower chance of approval. Finally, we find that approvals under the 2018 regulation are more likely when applicants are private entities from non‐EU countries and have substantial experience with novel foods. Our empirical evidence suggests that the new regulation may be insufficient to speed up and streamline the novel food assessment process, which is inevitably constrained by EU food safety principles. This, in turn, may discourage future investments.
