Authors: Wang Xiaopeng , Xie Yaping , Huang Yin , Chen Xurong 
Published: January 2024

Understanding the production mechanisms and utilizing them as probes to investigate the structure of exotic states represent some of the most actively studied research areas in particle physics. In this study, we present a theoretical analysis of the charmed meson Tcc− in the γp→D+Tcc−Λc+ and γγ→D+Tcc−D*0 reactions, considering Tcc+ as a DD* molecule. The differential cross section and total cross section for the photoproduction of Tcc− in the γp→D+Tcc−Λc+ and γγ→D+Tcc−D*0 reactions are presented for nucleus-nucleus (nucleon-nucleon) ultraperipheral collisions at HL-LHC and RHIC, respectively. Taking into account the integrated luminosity per typical run and the luminosity of photons from the nucleus (nucleon), we observe a significant event count for Tcc− production in p−p ultraperipheral collisions at HL-LHC.

Authors: Fan Shea X. , Duan Sophia Xiaoxia , Deng Hepu 
Published: January 2024

PurposeImproving digital work experience is critical for the job performance of individuals and the competitiveness of organizations due to their increasing use. This paper investigates how organization support affects the digital work experience of individuals differently depending on their levels of information technology (IT) identity.Design/methodology/approachDrawing upon the IT identity literature and the conservation of resources (COR) theory, a conceptual model is developed, tested and validated using the data collected in Australia through an experimental design in which IT identity is manipulated.FindingsThis study reveals a nuanced impact of organization support on shaping digital work experience. Specifically, it finds that technical support is more effective in improving the digital work experience of individuals with a high level of IT identity, whereas well-being support is more effective in enhancing the digital work experience of individuals with a low level of IT identity.Originality/valueThis research contributes to the IT identity literature by introducing a novel experimental design to manipulate IT identity in the digital work context. It also contributes to the digital work literature by introducing a resource perspective for identifying well-being support, technical support and IT identity as the key resources in shaping digital work experience and calling for attention to IT identity as a boundary condition on the effectiveness of organization support. The findings can help organizations formulate better strategies and policies to improve digital work experience by providing tailored support to individuals with different levels of IT identity.
Roldós y Compañía, the oldest operating advertising agency in the world
Authors: Serra Folch Carolina , Castellano Cristina Martorell 
Published: January 2024

Purpose
This paper aims to review the history of Roldós y Compañía, one of the oldest advertising agencies in the world and the oldest currently operating. This research aims to highlight the importance of this agency and its founder, Rafael Roldós Viñolas – the first documented advertising agent in Spain to this day – in shaping the emerging Spanish advertising industry at the end of the 19th century.

Design/methodology/approach
The methodology used in this paper is based on a review of period and contemporary literature, as well as on newspaper sources and documents from the private archive of Roldós, S.A.

Findings
In its early years, the agency’s participation in two of the most significant events for the modernization of the city of Barcelona, the Universal Exhibition of 1888 and the International Exhibition of 1929; as well as the ideation and implementation of several urban projects with the aim of finding new formulas and advertising media are factors that make it one of the most important in the country. In 1929, the alliance Roldós-Tiroleses, S.A. de Publicidad, the first great merger of advertising agencies in Spain, which lasted three years, was led. The outbreak of the Civil War and the subsequent post-war period marked a few years of business irregularities and advertising silences that gave instability to its activity. During the last third of the 20th century, the agency was immersed in the generalized advertising euphoria around the world. With the arrival of North American agencies in Barcelona and the consequent business movements, Roldós, S.A. specializes in the processing of advertisements and media planning. The 21st century began with important changes in the media planning sector, and the agency was forced to restructure its services and organizational structure. In 2022, it celebrates 150 years of uninterrupted activity, recognized by the country’s business sector.

Practical implications
This research aims to internationalize the history of the Roldós y Compañía agency, so that it can be studied together with other names of Anglo-Saxon advertising pioneers who were contemporaries of Rafael Roldós.

Originality/value
Scientific research on the history of advertising agencies, especially in Spain, is scarce, so this paper aims to help fill this gap.
Audit committee characteristics and firm performance: a cross-country meta-analysis
Authors: Altin Meltem 
Published: January 2024

PurposeThe purpose of this study is to investigate the impact of audit committee characteristics on firm performance. In particular, the authors employ the random-effects variant of the Hunter–Schmidt meta-analyze procedure to analyze the effects of key audit committee attributes, namely audit committee independence, audit committee expertise, audit committee size, audit committee meeting along with big four impact on firm performance. The authors hope to gain a better understanding of the function of audit committees in enhancing firm performance and to uncover potential discrepancies in prior findings due to varying economic levels or performance metrics.Design/methodology/approachThis study uses the Hunter–Schmidt method to conduct a meta-analysis of 39 previous studies published between 2012 and 2022 to investigate the relationship between audit committee characteristics and firm performance.FindingsThe results indicate that audit committee independence, expertise, size and affiliation with the big four have a significant and positive effect on firm performance, while audit committee meetings have a non-significant effect. Furthermore, findings suggest that companies should carefully consider the contextual factors that may impact the effectiveness of their corporate governance structures, such as economic level, when designing and implementing governance mechanisms.Originality/valueThis study is significant as it is the first to combine and analyze previous research on this topic and highlights the importance of certain audit committee characteristics in enhancing financial reporting quality and corporate governance.
The relationship between dietary polyamine levels, metabolic risk parameters and anthropometric measurements in postmenopausal women
Authors: Tari Selcuk Kevser , Atan Ramazan Mert , Arslan Sedat , Dal Nursel , Sahin Kezban 
Published: January 2024

Purpose
This study aims to investigate the relationship between dietary polyamine levels, metabolic risk parameters and anthropometric measurements in postmenopausal women.

Design/methodology/approach
This cross-sectional study was conducted with 562 45–64-year-old postmenopausal women who presented to a Family Health Center. To collect the data, the Descriptive Information Form and Food Frequency Questionnaire were used. In the data analysis, numbers, percentages, mean, standard deviation and multiple linear regression analysis were used.

Findings
The multiple linear regression analysis demonstrated that dietary putrescine intake was negatively associated with systolic blood pressure (ß = −0.179, p < 0.001), dietary spermidine intake was positively associated with waist circumference (WC) (ß = 0.142, p = 0.013), systolic blood pressure (ß = 0.188, p = 0.001), diastolic blood pressure (ß = 0.218, p < 0.001), body mass index (BMI) (ß = 0.169, p = 0.003) and waist-to-height ratio (WHtR) (ß = 0.156, p = 0.006), and dietary spermine intake was negatively associated with WC (ß = −0.158, p = 0.003), systolic blood pressure (ß = −0.195, p < 0.001), BMI (ß = −0.107, p = 0.042) and WHtR (ß = −0.138, p = 0.009).

Research limitations/implications
Owing to the study’s cross-sectional nature, the lack of succession in the cause–effect relationship, the use of self-report Food Frequency Questionnaire to determine dietary polyamine intake and the inability to analyze seasonal differences are among the limitations of the study.

Originality/value
In this study, an association was determined between dietary polyamines, metabolic risk parameters and anthropometric measurements. The findings suggest that dietary polyamines in human health should be further investigated owing to the increasing metabolic risk parameters.
Geometric analysis of early Ottoman tombs within the context of conservation studies
Authors: Niğdeli Zeynep Fatma , Gençer Funda , Yüksek İzzet 
Published: January 2024

PurposeThe purpose of the study is to provide a dataset about geometrical constructions of early Ottoman tombs for conservation studies. Thus, a proposal for the restitution phase of the damaged tombs aims to develop.Design/methodology/approachThe study is composed of four phases. First, the representative plan and section drawings of early Ottoman Tombs were redrawn; second, a geometrical analysis was made, a proposal table was prepared for the restitution of the damaged tombs; and last, this table was applied to tomb examples and restitution drawings are verified with the original situation of the tombs.FindingsEarly Ottoman tombs may be interpreted through geometric shapes, including the square, circle, triangle, octagon, arsin grid and quadrature systems. The arsin grid system provides information about the position of the domes and the height of the drums and windows. Quadrature establishes the highest point of domes and entrances. The proposal table, developed from the obtained results, facilitated the identification of the original elements, including the dome, drum, window and portal. This information is crucial for conducting further studies on restitution.Originality/valueThe abundance and dispersed nature of tomb structures compared to other architectural designs pose challenges in their scholarly examination. The early Ottoman tombs, which experienced an increase in numbers following the Conquest of Istanbul, serve as the initial expressions and embodiments of novel architectural endeavors. Thus, the determination of design ideas of the early Ottoman tombs sheds light on Ottoman architectural practice, which has remained largely unknown and guided the conservation studies of the tombs that have lost their integrity and originality.
An investigation into the mechanisms that influence laser sintered polyamide-12 top surfaces
Authors: Tarver James , Nar Kieran , Majewski Candice 
Published: January 2024

Purpose
The purpose of this paper is to elucidate the extent to which the mechanisms of polymer melt viscous flow and finish layer powder particle adhesion influence the top surface topographies of laser sintered polyamide (PA12) components.

Design/methodology/approach
Laser sintered specimens were manufactured at varying laser parameters in accordance with a full factorial design of experiments. Focus variation microscopy was used to ascertain insight into their top surface heights and peak/valley distributions. Subsequently, regression expressions were generated to model the former with respect to applied laser parameters. Auxiliary experimental analysis was also performed to validate the proposed mechanisms and statistical models.

Findings
Within the parameter range tested, this work found the root mean square (Sq) and skewness (Ssk) roughness responses of laser sintered PA12 top surfaces to be inversely related to one another, and both also principally influenced by beam spacing. Furthermore, it was demonstrated that using optimised laser parameters (to promote polymer melt dispersion) and building without finish layers (to avert subsequent powder particle adhesion) reduced the mean Sq roughness of resultant topographies by 30.8% and 47.9% relative to standard laser sintered PA12 top surfaces, respectively.

Practical implications
The scope to which laser sintered PA12 top surfaces can be modified was highlighted.

Originality/value
This research demonstrated the impact the mechanisms of polymer melt viscous flow and finish layer powder particle adhesion have on laser sintered PA12 top surfaces.

Published: January 2024

Abstract

The relationship between biodiversity and multitrophic ecosystem functions (BEF) remains poorly studied in forests. There have been inconsistent reports regarding the significance of tree diversity effects on ecosystem functions, which may be better understood by considering critical biotic interactions of trees.

This study investigates the role of tree‐mycorrhizal associations that may shape forest BEF relationships across multiple ecosystem functions. We used a field experiment (MyDiv) that comprises 10 deciduous tree species associated with either arbuscular mycorrhizal (AM) or ectomycorrhizal (EcM) fungi to create gradients in species richness (1, 2, 4 species) and different mycorrhizal communities (only AM‐species [AM fungi associated tree species] or EcM‐species [EcM fungi associated tree species], or a combination of both). We investigated the effects of tree species richness and mycorrhizal types on crucial multitrophic ecosystem functions (foliage damage, predation [using artificial caterpillars] and soil fauna feeding activity [~0–10 cm]) and assessed how these effects were mediated by stand characteristics.

Overall, we found that tree species richness and mycorrhizal types strongly affected multitrophic ecosystem functions. Compared to monocultures, 4‐species mixtures with both mycorrhizal types experienced significantly lower foliage damage. The mixtures of EcM‐species supported significantly higher predation (i.e. a greater proportion of artificial caterpillars being attacked), and this effect strengthened with tree species richness. The effects of tree species richness on soil fauna feeding activity were negative across all mycorrhizal types in the lower soil layer. Moreover, we showed that tree diversity effects were mediated by above‐ground tree biomass, vertical structural complexity and leaf quality, with the dominating mechanisms largely depending on the mycorrhizal types.

Synthesis. Tree species richness affected multitrophic ecosystem functioning by (1) directly decreasing the proportion of foliage damage in the communities with both mycorrhizal types, where AM‐species benefited from mixing with EcM‐species, and (2) increasing predation rates via changes in the vertical structural complexity in mixtures of EcM‐species. Our results highlight the importance of considering mycorrhizal types for managing well‐functioning mixed‐species forests and contribute to broadening the mechanistic understanding of the context‐dependent BEF relationships in forests.
THE MULTIPLE ENACTMENTS OF CONTAMINATION: Rethinking the Remediation and Redevelopment of Military‐Industrial Brownfields in the Tel Aviv Region
Authors: Ansenberg Uri , Marom Nathan 
Published: January 2024

AbstractThe remediation and redevelopment of industrially contaminated land are complex challenges for urban regions worldwide. Yet the literature on urban brownfields mostly addresses this as a technical problem through dichotomic and anthropocentric terms, contrasting the passive and negative role of the contamination as a toxic entity in the ground with the active and positive roles assigned to human actors such as planners, developers and communities. This article contests this prevalent view by tracing in detail debates concerning the remediation of three highly contaminated military‐industrial brownfield sites in the Tel Aviv metropolitan region. Drawing on notions of ontological multiplicity and enactment from science and technology studies and on qualitative analysis of a vast database of planning protocols and court hearings alongside interviews with key stakeholders, we uncover how contamination is enacted in multiple ways as mobile/immobile, unified/fragmented, remediable/irremediable. Furthermore, following one of our field's inherent controversies—whether to fully map the contamination prior to planning the sites—the article highlights the attempts to regulate this multiplicity and replace it with a single coherent contamination. By acknowledging the multiple enactments of contamination, our approach offers a more nuanced understanding that could help stakeholders rethink the remediation and redevelopment of urban brownfields beyond simplistic technical solutions or neoliberal policy imperatives.
Assessing the potential of ICT to increase land and labour productivity in agriculture: Global and regional perspectives
Authors: Rajkhowa Pallavi , Baumüller Heike 
Published: January 2024

AbstractIncreasing agricultural productivity in low‐ and middle‐income countries (LMICs) is an important channel for reducing poverty and food insecurity. Information and communication technologies (ICT) have the potential to boost agricultural productivity by lowering transaction costs and enhancing access to information. Even though there are several micro‐level studies analysing the effects of ICT on agricultural productivity, there is scant research addressing the role of ICT in agricultural productivity at the global and regional levels. Using data from 86 countries for the period 2000 to 2019 and utilising a fixed effect panel regression with a feasible generalised least square approach, we find that globally there is a positive and significant association between ICT uptake and both land and labour productivity in agriculture. In each case, however, the magnitude of the effect is much smaller than other important determinants, such as human capital, access to inputs or environmental factors. At the regional level, the relationship between ICT uptake and land productivity is not significant in Africa and Asia, while we find a significant effect on labour productivity. This finding indicates that while ICT can provide valuable information and tools for land management, the effect on land productivity might be less immediate in these regions. Finally, we revisit the question of whether ICT expansion increases agricultural productivity gaps between high‐income nations and LMICs. In contrast to previous research, this study does not find significant differences in the effects of ICT on land and labour productivity between higher‐income and lower‐income countries.

Published: January 2024

AbstractThe rapid advancement of three‐dimensional (3D) printing (i.e., a type of additive manufacturing) technology has brought about significant advances in various industries, including the food industry. Among its many potential benefits, 3D food printing offers a promising solution to deliver products meeting the unique nutritional needs of diverse populations while also promoting sustainability within the food system. However, this is an emerging field, and there are several aspects to consider when planning for use of 3D food printing for large‐scale food production. This comprehensive review explores the importance of food safety when using 3D printing to produce food products, including pathogens of concern, machine hygiene, and cleanability, as well as the role of macronutrients and storage conditions in microbial risks. Furthermore, postprocessing factors such as packaging, transportation, and dispensing of 3D‐printed foods are discussed. Finally, this review delves into barriers of implementation of 3D food printers and presents both the limitations and opportunities of 3D food printing technology.
The difference and variation of gut bacterial community and host physiology can support adaptation during and after overwintering in frog population
Authors: PARK Jun‐Kyu , DO Yuno 
Published: January 2024

AbstractThe hibernation of amphibians can offer a unique window into overwintering adaptation processes and host–gut microbiota interactions through changes in metabolic availability and homeostasis. We attempted to identify differences in the physiology and gut microbiome during and after hibernation in Japanese wrinkled frogs (Glandirana rugosa), an aquatic overwintering amphibian. After hibernation, the high alpha and beta diversity of the gut bacterial community appears to reflect the more diverse and complex environmental conditions. During winter, Proteobacteria dominated the majority of the gut bacterial community, likely due to high oxygen saturation. After hibernation, Firmicutes and Bacteroidetes increased, which are supportive of host metabolism by gut microbiota. Corticosterone also showed high values and variances after hibernation, presumably allowing the population to remain adaptable across a broad range of environmental gradients. Innate immunity was high after hibernation but exhibited low variation among populations, which supports the idea of a prioritized investment in immunity after hibernation. Blood biochemistry suggests that aquatic overwintering frogs have a mechanism to adapt through overhydration and regulate homeostasis through water excretion associated with the kidney and urine after hibernation. Frog populations exhibit variations and adaptability in gut microbiota and physiology during and after hibernation: Through this, they may demonstrate an adaptive response that regulates metabolic availability in preparation for unpredictable environmental changes. We also propose that the maintenance of Proteobacteria during hibernation can support the colonization of Firmicutes and Bacteroidetes after hibernation, underscoring the need to study the complex effects of gut microbiota across multiple life stages.
