Innovation knowledge exchange within Chaebols and the ownership structure of their foreign subsidiaries
Authors: Lee Hyoungjin , Lee Jeoung Yul
Published: March 2024

Purpose

This study examines how the characteristics of innovation knowledge exchanged among affiliate firms affect the ownership strategies adopted for their foreign subsidiaries.

Design/methodology/approach

This study employs a cross-classified multilevel model to examine a sample of 185 Korean manufacturing affiliates derived from 49 Chaebols engaged in international diversification, along with their 1,110 foreign manufacturing subsidiaries.

Findings

While exploratory innovation knowledge exchange lowers the affiliate's level of ownership in its foreign subsidiary, exploitative innovation knowledge exchange rather increases the affiliate's level of ownership in its foreign subsidiary.

Research limitations/implications

This study advances the literature on intrafirm knowledge exchange by highlighting it as a determinant of ownership strategies. The study further shows that the characteristics of knowledge exchanged at the affiliate level not only determine the ownership structure but also have the potential to shape the direction in which the subsidiary develops its competencies.

Practical implications

This study has practical implications for the managers of business group affiliates. The results suggest that managers should adapt their ownership strategies according to the type of knowledge exchanged at the affiliate level to achieve a balanced and synergistic effect on intraorganizational knowledge exchange.

Originality/value

Previous studies have extensively explored the performance implications related to knowledge exchange. However, there is a notable gap in understanding the mechanisms through which the value of knowledge transferred within an affiliate is realized. To address this gap, this study focuses on ownership strategy as a crucial factor and empirically examines how the characteristics of innovation knowledge exchanged among affiliate firms influence the ownership strategies adopted for their foreign subsidiaries. By investigating this relationship, this study provides valuable insights into the complex dynamics of knowledge exchange and its effect on ownership decisions within business group affiliates.

Authors: An Jing , Li Suicheng , Wu Xiao Ping
Published: March 2024

Purpose

Project managers bear the responsibility of selecting and developing resource scheduling methods that align with project requirements and organizational circumstances. This study focuses on resource-constrained project scheduling in multi-project environments. The research simplifies the problem by adopting a single-project perspective using gain coefficients.

Design/methodology/approach

It employs uncertainty theory and multi-objective programming to construct a model. The optimal solution is identified using Matlab, while LINGO determines satisfactory alternatives. By combining these methods and considering actual construction project situations, a compromise solution closely approximating the optimal one is derived.

Findings

The study provides fresh insights into modeling and resolving resource-constrained project scheduling issues, supported by real-world examples that effectively illustrate its practical significance.

Originality/value

The research highlights three main contributions: effective resource utilization, project prioritization and conflict management, and addressing uncertainty. It offers decision support for project managers to balance resource allocation, resolve conflicts, and adapt to changing project demands.
Family embeddedness and next generation aspirations to take over the family business: insights from the MENA region
Authors: Alshibani Safiya Mukhtar , Aljarodi Abdullah M.
Published: March 2024

Purpose

This study delves into the aspirations of young individuals to assume leadership roles in their family businesses. It assesses the impact of family embeddedness and the perception of positive family business performance on succession intentions and investigates potential gender differences in this context.

Design/methodology/approach

Hierarchical multiple regression was determined for utilizing a sample of university students in seven countries from the Middle East–North African (MENA) region (N = 3,908).

Findings

The present study’s findings suggest that embeddedness in the family business has a much stronger role in shaping the succession intentions than previously envisioned. Females are more inclined to take over the family business when they perceive that the family business is not performing well.

Originality/value

This study provides important insights into the dynamic of family business succession intentions and family embeddedness. By providing a better understanding of some of the key drivers of family business succession intentions, it enables families in the MENA region to develop better family plans to engage with their successors effectively.
Different countries, different institutions: how do brand-oriented SMEs leverage branding capabilities to boost export performance?
Authors: Ranjan Piyush
Published: March 2024

Purpose

This study aims to develop a moderated mediation model that enables the examination of the direct relationship between brand orientation (BO) and export performance, the mediating effects of external and internal branding capabilities on the BO-export performance link, and the moderating influence of institutional environment, i.e. regulatory turbulence and policy support.

Design/methodology/approach

A time-lag primary data was collected from two-wave survey of 684 cross-industry exporting small and medium-sized enterprises (SMEs) using an online-email based survey technique, and the research model was validated using ordinary least squares regression analysis in SPSSV.27 and Hayes’ PROCESS macroV.2.13.

Findings

Regression findings indicate that the relationship between BO and export performance is not direct, but rather mediated by means of both external and internal branding capabilities. It further helps to uncover the dual role of institutional environment, with regulatory turbulence weakening and policy support strengthening the indirect influences of BO on export performance via external and internal branding capabilities.

Research limitations/implications

This study advances branding literature by conceptualizing and empirically testing the role of BO associated with internal and external branding capabilities and, subsequently, with export performance.

Practical implications

The research findings indicate that brand-oriented SMEs must actively engage in the development of branding capabilities to improve their export performance.

Originality/value

While brand creation is essential for the success and growth of SMEs competing in the worldwide marketplaces, there is a dearth of research explaining the underlying mechanisms and boundary conditions through which BO influences export performance.
The role of sense of calling in the relationships between human resource practices, turnover intention and employee satisfaction in the hotel industry
Authors: Davras Özgür , Manap Davras Gonca
Published: March 2024

Purpose

The main aim of the present research is to investigate the role of sense of calling (SOC) in the relationships between human resource practices (HRP), turnover intention (TI) and employee satisfaction (ES) in the hotel industry. Moreover, it also examines whether the relationships between these variables are different for city and resort hotel employees.

Design/methodology/approach

Quantitative research was employed to test the proposed hypotheses, and the survey technique was used to collect data. The participants of the research consist of 432 hotel employees who work in Antalya, Turkey. The hypotheses were tested using the partial least squares structural equation modeling (PLS–SEM) analyses.

Findings

The results of the analysis have shown that SOC significantly impacts the ES and TI, and HRP could be a new antecedent of SOC. On the other hand, while ES is positively affected by HRP, the SOC has a moderating role in the relationship between these variables.

Practical implications

Hotel authorities' understanding of the SOC’s role in employee attitudes and behavior would be a significant factor not only in retaining them but also in reducing employee turnover. They should consider increasing employees' SOC by focusing on HRP.

Originality/value

Besides being one of the few studies that have discussed SOC in the hospitality literature, the current study also contributes by examining the role of SOC in the relationships between HRP, ES and TI. It also adds value to the calling literature by revealing whether the relationship between these variables differs for city and resort hotel employees.
Implementation of blockchain – IoT-based integrated architecture in green supply chain
Authors: Thakker Shivangi Viral , Rane Santosh B. , Narwane Vaibhav S.
Published: March 2024

Purpose

Digital supply chains require nascent technologies like blockchain and Internet of Things (IoT). There is a need to develop a roadmap for the implementation of these technologies, as they require a huge amount of resources and infrastructure. The purpose of this paper is to analyze the challenges of implementing blockchain-IoT integrated architecture in the green supply chain and develop strategies for the same.

Design/methodology/approach

After a thorough literature survey of Scopus-indexed journals and books, 37 barriers were identified, which were then brought down to 15 barriers after confirming with industry and academic experts using the Delphi method. Using the total interpretive structural modeling (TISM) method and cross-impact matrix multiplication applied to classification (MICMAC) analysis, the barriers were modeled, and finally, strategies were formulated using a concept map to handle the barriers in the blockchain-IoT integrated architecture for a green supply chain.

Findings

This paper presents the research on barriers that can be considered for incorporating blockchain and IoT in the green supply chain. It was found from the TISM model that environmental concerns are Level-1 barriers and need to be addressed by developing appropriate technology and allocating funds for the same. An integrated ecosystem with blockchain and IoT is developed.

Research limitations/implications

The focus of this study was on the challenges of blockchain and IoT; hence, it is required to extend the research and find challenges for different industries and also analyze the criteria using other multi-criteria decision-making (MCDM) methods. Further research is required for the integration of blockchain-IoT with supply chain functions.

Practical implications

The transformation of a traditional supply chain into a green supply chain is possible with the integration of technologies. This research work and the strategies developed are useful to managers and practitioners working on technology implementation. Planning resources and addressing key barriers is possible with the concept maps and architecture developed.

Social implications

Green supply chain management (SCM) is gaining importance in industry as well as the academic sector due to government Policies and norms worldwide for reducing emissions and encouraging environment-friendly production systems. Incorporating blockchain and IoT in a green supply chain will further digitize and increase transparency in supply chains.

Originality/value

We have done a categorization of all barriers based on the expert survey by academicians and industry experts from industries in India. The concept map helps in identifying possible solutions for the challenges and initiatives to be taken for the smooth integration of technologies in the green supply chain.
The final frontier: police culture for women in men’s spaces
Authors: Todak Natalie
Published: March 2024

Purpose

This study explores how police culture is experienced by women officers serving in positions where they are significantly underrepresented (i.e. leadership and elite specialty units) and the environmental factors that shape these experiences.

Design/methodology/approach

A qualitative analysis of transcripts from interviews with 71 women serving in male-dominated roles was conducted (N = 39 ranking women; N = 32 women on elite units).

Findings

Participants described five occupational, organizational and assignment-level factors that shaped their workplace experiences. While some contextual forces at play are similar for women working patrol (e.g. traditional police culture, the underrepresentation of women in law enforcement) unique position-level factors were also identified (e.g. the high-risk and consequential nature of the work).

Practical implications

While the cultural environment for women patrol officers has improved in the past few decades, the same cannot be said for women working in positions that are still dominated by men. More attention to this area of policing is needed to ensure gender diversity is achieved throughout organizations and not only in positions deemed suitable for women.

Originality/value

The study extends research on women in policing beyond the focus on patrol. Further, it explores the assignment- and rank-based perspectives of police culture, which are largely absent from the literature.
Active shooter incidents: training, safety, culture and officers’ support for prioritizing victims’ lives above their own
Authors: Phillips Scott W. , Kochel Tammy Rinehart
Published: March 2024

Purpose

Active shooter incidents have risen considerably in recent years, elevating public and law enforcement focus on improving response to these incidents. The contemporary policy for reacting to an active shooter event is for the officers who first arrive on the scene to move quickly to engage and neutralize a shooter, prioritizing victim safety and minimizing loss of life. This study provides a preliminary understanding of the police view regarding their role in active shooter events and their experiences with active shooter training.

Design/methodology/approach

We conducted a survey of 413 sworn personnel across three US cities. Analyses examine differences in officers’ training experiences across the agencies and predictors of a sense of duty to prioritize victims’ lives over that of officers.

Findings

Officers’ training experiences differed by agency, yet most officers supported a duty to sacrifice their lives to prioritize victims’ safety during active shooter incidents. Officers with more years of experience have lower odds of supporting a duty to sacrifice their lives to save victims during an active shooter situation relative to less experienced officers. Respondents who recall officer safety among the top three most memorable topics from their recent active shooter training also have lower odds of supporting a duty to sacrifice.

Originality/value

The authors add knowledge about police officers’ experiences with active shooter training and officers’ opinions about their role in responding to active shooter incidents. We discuss implications of the findings relative to police culture and training and suggest directions for future research.

Authors: Ershadi Mahmoud , Lijauco Fredelino
Published: March 2024

Purpose

In this paper, a systematic review of 284 articles published between 2015 and 2022 and a full-text thematic analysis of 70 selected articles was conducted to catalog and synthesize factors in a framework. Thematic analysis subsequently revealed 18 selective codes under three groups of drivers, barriers, and outcomes. These three groups were explained by four key aspects including organization, stakeholders, infrastructure, and business environment that set a framework for the digitalization of construction. The study finally concluded digitalization strategies with a focus on support mechanisms, government incentives, regulations, the transition from manual labor to technicians, organizational technology culture, methodology development, and innovation processes. Such strategies provide insight into prioritizing resources towards smooth digital transformation in construction businesses.

Design/methodology/approach

A two-stage methodology is adopted by undertaking a systematic literature review followed by thematic content analysis. This work concludes with an analysis of remaining research gaps and suggestions for potential future research.

Findings

In this paper, a systematic review of 284 articles published between 2015 and 2022 and a full-text thematic analysis of 70 selected articles was conducted to catalog and synthesize variables in a framework. Thematic analysis subsequently revealed a set of variables and factors describing construction digitalization under three groups of success factors, barriers, and outcomes. A critical content analysis of the representative studies was conducted to identify five future research trends as well as associated research gaps and directions on the topic.

Practical implications

This study contributes to practice by providing directions concerning the key strategies and priorities associated with the digitalization of construction businesses.

Originality/value

This ground-breaking research brings to light a classified set of factors that are important for the digitalization of construction businesses. The elicited framework contributes to the current body of knowledge by offering a unique conceptualization of both driving and adverse aspects for the seamless digital transformation of construction.
Young consumers’ impulse buying tendency on social media: an empirical analysis in Vietnam in light of the LST theoretical perspective
Authors: Pham Anh D. , Nguyen Huyen N. , Le Tra T.H. , Nguyen Huyen K. , Khuat Hang T. , Phan Huyen T.T. , Vu Hanh T.
Published: March 2024

Purpose

Social commerce has brought about a significant transformation in consumer experience due to diverse factors. As a result, users often find themselves prone to impulsive buying behaviour when exposed to such an environment. Prior research was limited to demonstrating the expanding influence of celebrities on social media and the linkage between social engagement and impulse buying context. Furthermore, the impulse buying tendency of consumers on social media in the context of celebrity posts has yet to be validated. This paper aims to assess the influence of consumer awareness, consumer trust and observational learning on the latent state-trait (LST) theory regarding celebrity posts on impulse buying tendencies.

Design/methodology/approach

The empirical research builds on a sample survey involving 750 students from the “Big Four” economics universities in Hanoi. The proposed model was analysed using a partial least squares structural equation modelling technique.

Findings

The authors find that consumer trust and observational learning from celebrity’ posts positively affect impulse buying tendency. Yet celebrity influence awareness directly impacts trust in celebrity’ posts rather than directly impacting impulse buying tendency. Perceiving the importance of interactive and authentic posts by a celebrity in influencing consumers’ purchase behaviour on social media, this research offers valuable insights for stakeholders in the digital celebrity sphere of communication and marketing.

Practical implications

Perceiving the importance of interactive and authentic posts by a celebrity in influencing consumers’ purchase behaviour on social media, this research offers valuable insights for stakeholders in the digital celebrity sphere of communication and marketing.

Originality/value

From a theoretical perspective, this expands the applicability of the LST theory in social commerce to promote impulse buying tendencies. Second, this contributes to the literature on the emerging phenomenon of social media celebrities, as existing literature does not clarify their influence on impulse buying behaviour. Third, this research applies the concept of observational learning in online shopping through key features of social media platforms, namely, likes, shares and comments, to investigate their influence on the impulse buying tendency of consumers. Concerning managerial implications, the authors propose practical recommendations for practitioners, particularly those involved or interested in the commercial services industry and social media marketing (namely, celebrities and partner companies).
Early life risk factors for adolescent mental health difficulties for individuals at risk of developmental language disorder
Authors: Fradley Kathryn , Oldfield Jeremy , Marshall Julie , Toseeb Umar
Published: March 2024

Young people with developmental language disorder (DLD) often have poorer mental health compared to those without DLD. However, not all young people with DLD experience such difficulties. Two hundred and eighty‐one young people at risk of DLD (45% Female; 53% White British) were identified from a UK based population‐cohort. Main caregivers completed questionnaires about their early life (<5 years) and their mental health (at 14 years). Parent–child conflict was revealed to be an early risk factor for all mental health outcomes, at age 14. Additionally, harsh discipline and second‐hand smoke predicted worse externalising problems, and gender differences predicted worse internalising problems. Further findings demonstrated that, as the number of risk factors increased, so did the severity of mental health difficulties.
Work environment and health of bank employees working from home: Lessons from the COVID‐19 pandemic
Authors: Azpíroz‐Dorronsoro Carla , Fernández‐Muñiz Beatriz , Montes‐Peón José Manuel , Vázquez‐Ordás Camilo José
Published: March 2024

Teleworking in the banking sector has increased considerably as a result of the outbreak of the COVID‐19 pandemic. This work examines the role that home work environment and organisational support for teleworking played in the health of bank employees who were forced to work from their homes during the health emergency. For this, the authors propose and test a structural equation model and a moderated serial mediation model using a sample of 1037 bank employees in Spain, obtained through an online self‐administered survey. The results reveal the direct and indirect effects of home physical conditions on health, mediated by family interference with work and technological overload. The results also show that the organisation's support for teleworking enhances the impact of home physical conditions on family interference and technological overload, also detecting that the indirect effects of physical conditions on health have been conditioned by the organisation's support for teleworking. The study therefore provides a better understanding of the impact of home environment on teleworkers' health and identifies useful strategies to improve the well‐being of bank employees who wish to work from home.
Age‐related cholesterol and colorectal cancer progression: Validating squalene epoxidase for high‐risk cases

Published: March 2024

As people age, the risk and progression of colorectal cancer (CRC), along with cholesterol levels, tend to increase. Nevertheless, epidemiological studies on serum lipids and CRC have produced conflicting results. We previously demonstrated that the reduction of squalene epoxidase (SQLE) due to accumulated cholesterol within cells accelerates CRC progression through the activation of the β‐catenin pathway. This study aimed to investigate the mechanism by which age‐related cholesterol accumulation within tissue accelerates CRC progression and to assess the clinical significance of SQLE in older individuals with elevated CRC risk. Using machine learning‐based digital image analysis with fluorescence‐immunohistochemistry, we assessed SQLE, GSK3βpS9 (GSK3β activity inhibition through serine 9 phosphorylation at GSK3β), p53 wild‐type (p53WT), and p53 mutant (p53MT) levels in CRC tissues. Our analysis revealed a significant reduction in SQLE, p53WT, and p53MT and increase in GSK3βpS9 levels, all associated with the substantial accumulation of intra‐tissue cholesterol in aged CRCs. Cox analysis underscored the significant influence of SQLE on overall survival and progression‐free survival in grade 2–3 CRC patients aged over 50. SQLE and GSK3βpS9 consistently exhibited outstanding prognostic and diagnostic performance, particularly in older individuals. Furthermore, combining SQLE with p53WT, p53MT, and GSK3βpS9 demonstrated a robust diagnostic ability in the older population. In conclusion, we have identified that individuals aged over 50 face an increased risk of CRC progression due to aging‐linked cholesterol accumulation within tissue and the subsequent reduction in SQLE levels. This study also provides valuable biomarkers, including SQLE and GSK3βpS9, for older patients at elevated risk of CRC.
The utility of non‐lethal morphometrics to evaluate fish condition
Authors: Newbery Beaudee , Connolly Rod M. , Melvin Steve D. , Sievers Michael
Published: March 2024

The condition of fish relates to their energy reserves, and a suite of proxies exist to approximate condition, including biochemical and morphometric indices. Biochemical indices directly measure energy stores but are expensive and sometimes lethal. Morphometrics offer several advantages, but their utility as condition proxies is debated and largely untested experimentally. Here, we manipulated the condition of yellowfin bream (Acanthopagrus australis, Günther, 1859) via food reduction to simulate the effect of poor habitat quality and calculated a variety of condition indices through time. We measured four non‐lethal morphometrics (Fulton's K, Le Cren's relative condition, width‐to‐length ratio and girth), the hepatosomatic index and a biochemical benchmark (liver lipid content). Girth and width‐to‐length ratio were reasonably well correlated with lipid content (R2 = 0.74 and 0.56, respectively). The hepatosomatic index was only weakly or uncorrelated to other indices, including lipid content (R2 = 0.35). Where precise estimates of body condition are not needed or repeat measures on the same individual are useful, non‐lethal morphometrics provide a fast, cheap and non‐lethal alternative to biochemical and lethal morphometric methods for this species. We finish by outlining how artificial intelligence‐based automation can be combined with morphometrics to further enhance ethical monitoring by eliminating the need to capture and handle fish entirely.
Tree and grass competition in savannas: Interactive effects of soil moisture, grass defoliation and grass species identity on the growth and survival of tree seedlings
Authors: Rugemalila Deusdedith M. , Sarakikya Jeremiah , Anderson T. Michael
Published: March 2024

We experimentally examined the influence of grass competition, grass species identity (taxa) and water availability on the seedling growth and survival of two dominant tree species (Vachellia (formerly Acacia) robusta and V. tortilis) of the Serengeti National Park in Tanzania. Despite being widely distributed, the species have an opposing overstorey dominance across a rainfall and productivity gradient, with V. robusta dominating the more productive mesic sites and V. tortilis in the lower productivity, drier sites. We investigated the role of different grass species, which vary in distribution and abundance across the rainfall gradient, in influencing the growth and survival of Vachellia seedlings. We found a significant effect of grass competition but no effect of grass species identity on the growth or survival of seedlings. Seedling survival was highest in the absence of grass competition, intermediate when grasses were defoliated to simulate grazing and lowest when grown with ungrazed grasses. Grass competition had a more negative effect on the stem diameter of V. tortilis than V. robusta. All V. tortilis seedlings grown under a combination of drought conditions and unclipped grasses died by the end of the experiment. However, reduced grass competition by simulated grazing improved V. tortilis seedling survival to comparable levels achieved by V. robusta species. Our study advances our understanding of tree and grass competition across environmental gradients and suggests that the presence of grass and soil moisture have species‐specific effects on tree seedling growth and survival in African savannas.

Published: March 2024

Aim

Psychotropic medication can contribute to arrhythmia and identifying individuals at risk is crucial. This Swedish study compared the corrected QT (QTc) intervals of adolescents on psychotropic medication with unmedicated controls, when supine and after rising rapidly.

Methods

The study was carried out at Östersund County Hospital in March 2022 and February to March 2023. It comprised 16 cases, aged 10–17 years and 28 controls. QTc intervals were measured with electrocardiography and calculated using Bazett's and Fridericia's formulas. Univariate and multiple linear regressions were used to assess differences in QTc intervals between the cases and controls and across sex, age and body mass index.

Results

The mean QTc interval when supine, calculated with Bazett's formula, was longer for the adolescents on psychotropic medication than the controls (p = 0.046). The same was true for the mean QTc interval after rising rapidly from the supine position, calculated with both Bazett's formula (p = 0.009) and Fridericia's formula (p = 0.007). Mean QTc intervals varied by sex and age groups. Psychotropic medication prolonged QTc intervals, particularly in girls.

Conclusion

Longer QTc intervals were found in adolescents on psychotropic medication, particularly after rising rapidly from the supine position.
Ethics and compliance programs for a new business narrative: A Kohlberg‐based moral valuing model for diagnosing commitment at the top
Authors: Hernández‐Cuadra Esperanza , Fernández‐Fernández José‐Luis
Published: March 2024

A genuine commitment to ethics and compliance (E&C) programs means that top management adopt them for what they represent and not for other purposes. Only then can they truly build socially responsible behavior and a successful and sustainable business, as stated in the latest international standard for compliance management practice (ISO 37301:2021), which we found to be consistent with a new business narrative as conceptualized in Freeman's work. However, it also requires that top managers place a moral value on these practices, rather than simply using them for instrumental reasons. Building on Kohlberg's six stages of moral development as applied to managers' moral thinking, this manuscript offers a model to explain how top managers' moral valuing of these practices varies along a moral reasoning continuum, resulting in four distinct modes. It also theorizes that each mode of moral valuing yields an archetype of E&C programs. It thus offers a new approach that contributes to the business ethics and management literature by incorporating a morally grounded perspective on the adoption and implementation of E&C practices and how it might shape their features and characteristics. It also aims to improve professional practice and business contributions to Freeman's ideas through genuine ethics‐based E&C programs.
Network structure of adolescent social, emotional, and behavioral difficulties and their differential relationships with suicidality
Authors: Xie Tong , Jiang Wanyue , Liu Xiaoyan , Wang Jianping
Published: March 2024

Background

Social, emotional, and behavioral difficulties (SEBDs) tend to develop during adolescence. Their presence and especially co‐occurrence induce numerous disrupting consequences, including suicidality. A recently developed network analysis is suitable to investigate the symptom‐level structure of comorbid psychopathology. Rather than pairwise comorbidity networks, the current study investigated a comprehensive network of SEBDs at the symptom level and explored the differential relationships between symptoms of SEBDs and suicidality.

Methods

Recruited from four public schools in China, a sample of adolescents (N = 6974, mean age = 15.84, 50.1% boys) were assessed with the Strengths and Difficulties Questionnaire (SDQ) and one suicidality‐related item. The cross‐sectional network structure of the SEBD symptoms was investigated. The differential associations between individual symptoms of SEBDs and suicidality were also explored with a relative importance analysis.

Results

The results showed that constantly fidgeting, worry a lot, unhappy, down‐hearted, tearful, and easily scared emerged as the most central symptoms in the network of SEBDs. Worry a lot, constantly fidgeting, lose my temper, and being bullied served as bridge symptoms, connecting various domains of SEBDs. In addition, the centrality of symptoms was positively associated with the variance shared with suicidality, with worry a lot and unhappy, down‐hearted, and tearful explaining a large portion of the variance of suicidality.

Conclusions

Taken together, the results were indicative of close connections among emotional, hyperactivity‐inattention, peer, and conduct aspects of adolescent mental health difficulties, as well as the central role of emotional difficulties in the SEBDs network.
Age differences in generalization, memory specificity, and their overnight fate in childhood
Authors: Buchberger Elisa S. , Joechner Ann‐Kathrin , Ngo Chi T. , Lindenberger Ulman , Werkle‐Bergner Markus
Published: March 2024

Memory enables generalization to new situations, and memory specificity that preserves individual episodes. This study investigated generalization, memory specificity, and their overnight fate in 141 4‐ to 8‐year‐olds (computerized memory game; 71 females, tested 2020–2021 in Germany). The results replicated age effects in generalization and memory specificity, and a contingency of generalization on object conceptual properties and interobject semantic proximity. Age effects were stronger in generalization than in memory specificity, and generalization was more closely linked to the explicit regularity knowledge in older than in younger children. After an overnight delay, older children retained more generalized and specific memories and showed greater gains but only in generalization. These findings reveal distinct age differences in generalization and memory specificity across childhood.

Objectives

Dental behaviour support (DBS) describes all specific techniques practiced to support patients in their experience of professional oral healthcare. DBS is roughly synonymous with behaviour management, which is an outdated concept. There is no agreed terminology to specify the techniques used to support patients who receive dental care. This lack of specificity may lead to imprecision in describing, understanding, teaching, evaluating and implementing behaviour support techniques in dentistry. Therefore, this e‐Delphi study aimed to develop a list of agreed labels and descriptions of DBS techniques used in dentistry and sort them according to underlying principles of behaviour.

Methods

Following a registered protocol, a modified e‐Delphi study was applied over two rounds with a final consensus meeting. The threshold of consensus was set a priori at 75%. Agreed techniques were then categorized by four coders, according to behavioural learning theory, to sort techniques according to their mechanism of action.

Results

The panel (n = 35) agreed on 42 DBS techniques from a total of 63 candidate labels and descriptions. Complete agreement was achieved regarding all labels and descriptions, while agreement was not achieved regarding distinctiveness for 17 techniques. In exploring underlying principles of learning, it became clear that multiple and differing principles may apply depending on the specific context and procedure in which the technique may be applied.

Discussion

Experts agreed on what each DBS technique is, what label to use, and their description, but were less likely to agree on what distinguishes one technique from another. All techniques were describable but not comprehensively categorizable according to principles of learning. While objective consistency was not attained, greater clarity and consistency now exists. The resulting list of agreed terminology marks a significant foundation for future efforts towards understanding DBS techniques in research, education and clinical care.

Published: March 2024

Our aim was to evaluate biomarkers for organic anion transporting polypeptide 1B1 (OATP1B1) function using a hypothesis‐free metabolomics approach. We analyzed fasting plasma samples from 356 healthy volunteers using non‐targeted metabolite profiling by liquid chromatography high‐resolution mass spectrometry. Based on SLCO1B1 genotypes, we stratified the volunteers to poor, decreased, normal, increased, and highly increased OATP1B1 function groups. Linear regression analysis, and random forest (RF) and gradient boosted decision tree (GBDT) regressors were used to investigate associations of plasma metabolite features with OATP1B1 function. Of the 9152 molecular features found, 39 associated with OATP1B1 function either in the linear regression analysis (p < 10−5) or the RF or GBDT regressors (Gini impurity decrease > 0.01). Linear regression analysis showed the strongest associations with two features identified as glycodeoxycholate 3‐O‐glucuronide (GDCA‐3G; p = 1.2 × 10−20 for negative and p = 1.7 × 10−19 for positive electrospray ionization) and one identified as glycochenodeoxycholate 3‐O‐glucuronide (GCDCA‐3G; p = 2.7 × 10−16). In both the RF and GBDT models, the GCDCA‐3G feature showed the strongest association with OATP1B1 function, with Gini impurity decreases of 0.40 and 0.17. In RF, this was followed by one GDCA‐3G feature, an unidentified feature with a molecular weight of 809.3521, and the second GDCA‐3G feature. In GBDT, the second and third strongest associations were observed with the GDCA‐3G features. Of the other associated features, we identified with confidence two representing lysophosphatidylethanolamine 22:5. In addition, one feature was putatively identified as pregnanolone sulfate and one as pregnenolone sulfate. These results confirm GCDCA‐3G and GDCA‐3G as robust OATP1B1 biomarkers in human plasma.
Do management practices matter in further education?
Authors: McNally Sandra , Schmidt Luis , Valero Anna
Published: March 2024

Further education and sixth form colleges are key institutions for facilitating skill acquisition among 16–19 year olds in the UK. They enrol half a school cohort after completion of their lower secondary education, and this includes a disproportionate number from low‐income backgrounds. Yet little is known about what could improve performance in these institutions. We conduct the world's first management practices survey in such institutions, and match this to administrative longitudinal data on over 40,000 students. Value‐added regressions with rich controls suggest that structured management matters for educational outcomes, especially for students from low‐income backgrounds. For this group, in a hypothetical scenario where an individual is moved from a college at the 10th percentile of management practices to the 90th, this would be associated with 8% higher probability of achieving a good high school qualification, nearly half of the educational gap between those from poor and non‐poor backgrounds. Hence improving management practices may be an important channel for reducing inequalities.

Objectives

Responsive neurostimulation (RNS) is an established therapy for drug‐resistant epilepsy that delivers direct electrical brain stimulation in response to detected epileptiform activity. However, despite an overall reduction in seizure frequency, clinical outcomes are variable, and few patients become seizure‐free. The aim of this retrospective study was to evaluate aperiodic electrophysiological activity, associated with excitation/inhibition balance, as a novel electrographic biomarker of seizure reduction to aid early prognostication of the clinical response to RNS.

Methods

We identified patients with intractable mesial temporal lobe epilepsy who were implanted with the RNS System between 2015 and 2021 at the University of Utah. We parameterized the neural power spectra from intracranial RNS System recordings during the first 3 months following implantation into aperiodic and periodic components. We then correlated circadian changes in aperiodic and periodic parameters of baseline neural recordings with seizure reduction at the most recent follow‐up.

Results

Seizure reduction was correlated significantly with a patient's average change in the day/night aperiodic exponent (r = .50, p = .016, n = 23 patients) and oscillatory alpha power (r = .45, p = .042, n = 23 patients) across patients for baseline neural recordings. The aperiodic exponent reached its maximum during nighttime hours (12 a.m. to 6 a.m.) for most responders (i.e., patients with at least a 50% reduction in seizures).

Significance

These findings suggest that circadian modulation of baseline broadband activity is a biomarker of response to RNS early during therapy. This marker has the potential to identify patients who are likely to respond to mesial temporal RNS. Furthermore, we propose that less day/night modulation of the aperiodic exponent may be related to dysfunction in excitation/inhibition balance and its interconnected role in epilepsy, sleep, and memory.

Background

Helicobacter pylori (H. pylori) is a rod‐shaped, gram‐negative, microaerophilic bacterium that can be identified by gram staining. Its relationship with cancer is significant since it is involved in approximately 80% of gastric cancers and 5.5% of all malignant cancers. Two lines of treatment have been defined for H. pylori, but almost 40% of patients do not respond to the first line. Recent trials have investigated oral Immunotherapy as a new treatment method. The aim of this systematic review was to investigate the potential effects of oral Immunotherapy on eradication rate of H. pylori in human studies.

Methods

The systematic review was performed according to PRISMA guidelines. We searched online databases, including Scopus, PubMed, and Web of Science (ISI). Our search strategy was limited to English articles and studies on human populations that use oral immunotherapy for H. pylori.

Results

The total number of primary research records in different databases was 2775. After removing duplicate articles (n = 870), we excluded 1829 for reasons including non‐human studies, irrelevance to our study objective, non‐English language, or lack of information. Of the remaining 76 articles, only seven had sufficient information, and the rest were excluded. The studies were divided into two groups: those that used bovine antibody and those that used immunoglobulin Y to eradicate H. pylori.

Conclusion

In the group of Immunoglobulin Y, three out of four studies suggest that using Immunoglobulin Y for the treatment of H. pylori infection is significant. However, the group using bovine antibody for the treatment of H. pylori infection has various results, as two out of three studies concluded that bovine antibody therapy is not significant.
Politics and entry deterrence: Evidence from China's industrial land market
Authors: Wang Chunyang
Published: March 2024

This paper examines one million land transactions and firm census data sets to determine the effect of market concentration on entry deterrence in China from 2006 to 2013. We find that a one standard deviation increase in the Herfindahl–Hirschman Index leads to a one standard deviation decrease in local government‐designated industrial land sales to nonlocal firms and to a 2.9 standard deviation increase in land cost. Further evidence suggests that firms with high market power lobby their local governments to deter the entry of nonlocal firms.
Measuring Monetary Policy Shocks in Emerging Economies: Evidence from India
Authors: LAKDAWALA AEIMIT , SENGUPTA RAJESWARI
Published: March 2024

In this paper, we provide a template for constructing monetary policy shocks for emerging economies. Our approach synthesizes financial data with a narrative analysis of central bank communication and related media coverage. We create a publicly available time‐series database of policy dates and shocks for the Reserve Bank of India (RBI). Our shocks suggest that financial markets infer information about the future path of policy rate from RBI communication. Bond and stock markets react strongly to these monetary shocks but exhibit heterogeneity across governor regimes. Finally, we use the shocks as external instruments to identify the impact on macro‐economic variables.
