Determinants of the relationship between related party transactions and firm value: evidence from Saudi Arabia
Authors: Alsultan Abdulaziz Sulaiman 
Published: August 2023

PurposeThis study aims to examine the association between related party transactions and firm value. The study also investigates the impact of several determinants of this relationship as moderating variables.Design/methodology/approachThe paper uses multiple regression models. In the period from 2018 to 2021, a total of 134 non-financial companies listed on the Saudi Stock Exchange were included in the sample, which consisted of 451 firm-year observations.FindingsThis paper finds that related party transactions have a significant negative impact on firm value. Moreover, the negative impact of related party transactions on firm value is increased in the presence of changes in the certain presence of certain moderating variables, such as firm size, leverage and return on assets (ROA). The results of the sensitivity analysis concur with the findings of the basic analysis. There is little evidence in the literature regarding related party transactions and their association with the moderating variables considered in this study.Originality/valueTo the best of the authors’ knowledge, there have been no studies conducted in Saudi Arabia to date that examine the effect of firm size, leverage and ROA on the association between firm value and related party transactions. Consequently, this paper contributes to the limited literature by expanding the existing research and analyzing the impact of firm size, leverage and ROA on the association between related party transactions and firm value.

Published: August 2023

PurposeThis study aims to explore the relationship between elderly users' trust in public digital cultural services (PDCS) and their intention to use PDCS, and reveal the factors affecting their intentions from the perspective of trust to make recommendations that will increase their intention to use PDCS.Design/methodology/approachCombined with the trust building model and social exchange theory, this study constructed a conceptual model of elderly users' intention to use PDCS. Data collected from Chinese elderly users who have reached the age of 60 through questionnaire surveys were tested using the structural equation model with partial least squares. Finally, the authors proposed a model of elderly users' intention to use PDCS.FindingsThis study finds that elderly users' trust positively affects their intention to use PDCS from two aspects: service features and user features of PDCS. Concerning the service features, system quality directly affects elderly users' trust in PDCS most significantly, followed by information quality and service reputation. Concerning the user features, perceived value has a higher impact on elderly users' trust than that of service features, and information literacy and information quality directly affect perceived value.Originality/valueThis study adds new knowledge to the users' behavior of PDCS and enriches the prior description of PDCS. The recommendations made in this study provide a series of strategies for practitioners and researchers to improve the elderly users' intention to use PDCS and bridge the silver digital divide, which offers new ideas for improving the efficiency of PDCS.
The influence of competitive personality on rationalized knowledge hiding among Chinese employees
Authors: Wu Dongmei , Liu Ersi 
Published: August 2023

Purpose
The purpose of this paper is to examine the relationship between competitive personality (CMP) and rationalized knowledge hiding (KH) and to explore the mediating effects of knowledge-based psychological ownership (KPO) and organization-based PO (OPO) by developing a mediating framework.

Design/methodology/approach
Data were collected from the ordinary employees of listed companies in China (2022) via a Web-based survey. The total number of valid samples was 337. Confirmatory factor analysis was used to test the reliability and validity of the constructs, and structural equation modeling was used to verify the direct and mediating effects.

Findings
The findings revealed a positive relationship between CMP and rationalized KH (RKH). KPO plays a positive mediating role between CMP and RKH, whereas OPO plays a negative mediating role between CMP and RKH.

Research limitations/implications
First, although the questionnaire collection is split into two sessions to reduce common method variation, there is inevitably some risk, as the questionnaires are all reported by the same respondent. Second, this study examined the effects of CMP on RKH based on the Chinese cultural context, but the applicability of this finding to cross-cultural contexts warrants further study. In the future, researchers can conduct cross-cultural comparisons to determine the generalizability of the findings.

Practical implications
This study helps managers to better identify the RKH behaviors that exist in organizations, understand the reasons and processes behind employees’ KH and facilitate more effective knowledge management by managers.

Originality/value
This study uses CMP as an important indicator of employees’ RKH behavior, enriches the research related to the antecedent variables of RKH and reveals the influence mechanism between CMP and RKH from the perspective of PO, and the findings can help researchers and managers understand the process and antecedents of RKH so that timely interventions can be implemented.
The great obstetrical syndromes and the placenta
Authors: Hoffman Matthew K. 
Published: August 2023

AbstractAlthough historically pre‐eclampsia, preterm birth, abruption, fetal growth restriction and stillbirth have been viewed as clinically distinct entities, a growing body of literature has demonstrated that the placenta and its development is the root cause of many cases of these conditions. This has led to the term ‘the great obstetrical syndromes’ being coined to reflect this common origin. Although these conditions mostly manifest in the second half of pregnancy, a failure to complete deep placentation (the transition from histiotrophic placentation to haemochorial placenta at 10–18 weeks of gestation via a second wave of extravillous trophoblast invasion), is understood to be key to the pathogenesis of the great obstetrical syndromes. While the reasons that the placenta fails to achieve deep placentation remain active areas of investigation, maternal inflammation and thrombosis have been clearly implicated. From a clinical standpoint these mechanisms provide a biological explanation of how low‐dose aspirin, which affects the COX‐1 receptor (thrombosis) and the COX‐2 receptor (inflammation), prevents not just pre‐eclampsia but all the components of the great obstetrical syndromes if initiated early in pregnancy. The optimal dose of low‐dose aspirin that is maximally effective in pregnancy remains a question open for further research. Additionally, other candidate medications have been identified that may also prevent pre‐eclampsia, and further study of them may offer therapeutic options beyond low‐dose aspirin. Interestingly, three of the eight identified compounds (hydroxychloroquine, metformin and pravastatin) are known to decrease inflammation.
New trends in the development of photodynamic inactivation against planktonic microorganisms and their biofilms in food system

Published: August 2023

AbstractThe photodynamic inactivation (PDI) is a novel and effective nonthermal inactivation technology. This review provides a comprehensive overview on the bactericidal ability of endogenous photosensitizers (PSs)‐mediated and exogenous PSs‐mediated PDI against planktonic bacteria and their biofilms, as well as fungi. In general, the PDI exhibited a broad‐spectrum ability in inactivating planktonic bacteria and fungi, but its potency was usually weakened in vivo and for eradicating biofilms. On this basis, new strategies have been proposed to strengthen the PDI potency in food system, mainly including the physical and chemical modification of PSs, the combination of PDI with multiple adjuvants, adjusting the working conditions of PDI, improving the targeting ability of PSs, and the emerging aggregation‐induced emission luminogens (AIEgens). Meanwhile, the mechanisms of PDI on eradicating mono‐/mixed‐species biofilms and preserving foods were also summarized. Notably, the PDI‐mediated antimicrobial packaging film was proposed and introduced. This review gives a new insight to develop the potent PDI system to combat microbial contamination and hazard in food industry.

AbstractPostharvest fungal attacks on fruits such as apricots and loquats are common. Diseased fruit samples were collected from Murree's local fruit markets. The disease‐causing pathogens were identified utilizing molecular, microscopic, and morphological characteristics. Alternaria alternata and Aspergillus niger were identified as the pathogens responsible for brown rot in loquat and black rot in apricot. To combat these fruit diseases, iron oxide (Fe2O3) nanoparticles were synthesized using Bacillus subtilis and were characterized using various techniques. X‐ray diffraction examination validated the size of iron oxide nanoparticles. The presence of several capping agents in the synthesized nanoparticles was confirmed by Fourier transform infrared analysis. Scanning electron microscopy revealed the spherical morphology of nanoparticles, whereas energy‐dispersive X‐ray proved the presence of different elemental compositions. After completing antifungal activities in vitro and in vivo, it was discovered that a nanoparticle concentration of 1.0 mg/mL efficiently suppressed the growth of fungal mycelia. Fungi growth was effectively inhibited in fruit samples treated with 1.0 mg/mL nanoparticles. The results of successful in vitro and in vivo antifungal activities imply that iron oxide (Fe2O3) nanoparticles play an important role in ensuring fruit quality against pathogenic attacks. Bacterial‐mediated iron oxide can be widely used because it is less expensive and less harmful to the environment than chemically manufactured fertilizers.

AbstractA hybrid smart solar dryer (HSSD) based on indirect forced convection and a controlled auxiliary heating system was developed, fabricated, and tested to be convenient for sunny and cloudy weather conditions. The achievements of the developed dryer focus on controlling the temperature of the dryer, increasing the drying rate, reducing energy consumption, and providing high‐quality products. The HSSD was tested and evaluated for drying basil and sage herbs at 30, 40, and 50°C. The results showed that the fresh basil and sage leaves of 1 kg with a moisture content of 84.7% and 75.53% (wet basis) were dried within 58, 46, 32 and 38, 28, and 20 h at 30, 40, and 50°C, respectively. Correspondingly, the traditional drying methods achieved 96 h outdoors and 144 h indoors at room temperature. The average of the fabricated flat‐plate solar collector efficiency (thermal efficiency, ηfpsc) was ranged from 49.18% ± 9.52% to 66.02% ± 2.8%. The highest drying rates were achieved with the HSSD method. Moreover, the HSSD method led to a remarkable saving in energy with values ranging from 25.54% to 77.1% versus the traditional drying methods. While the best quality in terms of essential oil content and microbial load for the dried basil and sage herbs was achieved by the HSSD at 40°C. Finally, the HSSD is a promising energy‐efficient method where it can save 70% of energy consumption, thus reducing the carbon footprint of drying processes, and providing higher quality products compared to the conventional methods.
New architectures for bottom‐up science diplomacy: Learning from the evolving Portuguese diaspora in the UK
Authors: Lacerda Luís Miguel , Heitor Manuel , Mauduit Jean‐Christophe 
Published: August 2023

AbstractScientific diasporas and related non‐state actors have increasingly been coming into play to permeate and promote modern science diplomacy. However, these non‐formal collaborative architectures are particularly complex to sustain, and their systematic and long‐term action rely very much on conjunctural and, above all, individual engagement. The paper provides a multi‐stakeholder perspective that analyses the creation, during the lead‐up to Brexit, of the first ever scientific advisory board (SAB) at a Portuguese Embassy. In particular, it focuses on the interplay between bottom‐up diaspora initiatives and top‐down government actions. Our evidence is based on the experience of the development of a non‐formal and non‐hierarchical collaborative architecture established between Portuguese diplomats and the Portuguese scientific diaspora in the United Kingdom in the time of Brexit. The paper draws on lessons learnt that could be useful to other countries when engaging with their respective scientific diasporas.
Family ownership and speed of adjustment towards targeted capital structures: A study of ASEAN firms
Authors: Nguyen Lan Thi Mai , Khanh Tran Trang , Truong Cameron 
Published: August 2023

AbstractUtilising a sample of ASEAN firms, we examine the effects of family ownership on firms' speed of adjustment to targeted capital structure. We find that family firms adjust their capital structure more slowly than non‐family firms. This is due to the higher costs of adjustment associated with high information asymmetry and agency conflicts between family owners and external investors. The effect of family ownership on capital structure adjustment speed is more pronounced when family firms have a higher level of family board involvement and higher ownership concentration. There is also an asymmetric effect of family ownership on capital structure adjustment speed at different levels of debt, by the distance from the targeted capital structure, and between overleveraged and underleveraged firms. Overall, evidence in our study suggests that family ownership is a key determinant on how quickly ASEAN firms may adjust their capital structure towards targeted levels.

AbstractCohesive families and stimulating and caring environments promoting attachment to caregivers is fundamental for a child's physical and psychosocial growth and development. Parental care, supporting early years development, presupposes the presence and involvement of parents in children's daily life with activities that include breastfeeding, playing, reading and storytelling. However, parents have to balance their child's well‐being against employment, career progression and gender equality. Universally accessible and equitably available parental leave addresses this challenge.ConclusionDistinct from compulsory maternity leave, leave at full or nearly full pay for both parents benefits not only families but also societal well‐being and prosperity.

AbstractAimThis study aimed to assess the safety of a commonly used sedative, dexmedetomidine in neonates and infants during intensive care.MethodsA retrospective cohort study was conducted in the paediatric intensive care unit at Oulu University Hospital. The study population consisted of all children from birth up to 6 months of age who received dexmedetomidine during 2010–2016. Adverse cardiovascular outcomes were defined as abnormal heart rates or blood pressure values according to the Paediatric Early Warning Score.ResultsOf the 172 infants, 56% had congenital malformation, and 48% had undergone surgery. Neonates and 1–3‐month‐olds experienced bradycardia (86% vs. 73% in 1–3‐month‐olds and 50% in 3–6‐month‐olds, p = 0.001) and severe bradycardia (17% vs. 14% in 1–3‐month‐olds and 0% in 3–6‐month‐olds, p = 0.005) more often than older patients. The median maximum rate of dexmedetomidine infusion was 0.86 μg/kg/h (IQR = 0.60–1.71 μg/kg/h). A dose‐dependent increase in bradycardia and severe hypotension was found. Adverse cardiovascular events were managed with additional fluid boluses and discontinuation of the infusion.ConclusionAdverse cardiovascular events were common during dexmedetomidine administration in neonates and infants. Lower dexmedetomidine doses may be required in sedating neonates.
Chapter 10 Archaeologists as Indian Advocates? Lessons from Skinner, the Little‐Weasel; Moorehead, the Indian Commissioner; and Other Predecessors
Authors: Beisaw April M. 
Published: August 2023

ABSTRACTArchaeologists who study the Native past have a responsibility to the Native present. But our academic training does little to prepare us for advocacy work. Personal interests, ethics, and the precariousness of employment often dictate what can be done. Doing nothing is easier and safer than speaking out, but idleness reinforces the irrelevancy of archaeology to contemporary social issues. Recalling the advocacy decisions of two archaeological ancestors, Alanson B. Skinner and Warren K. Moorehead, helps us to consider how and when archaeologists should act beyond their own job descriptions. Skinner's attempts to educate the White‐public and Moorehead's work to guide governmental policies were not flawless. But their willingness to do something helps us reconsider if we, as individual archaeologists, are doing enough. First and foremost, archaeologists should ensure that their institutions have complied with the spirit of the Native American Graves Protection and Repatriation Act, not just the letter of the law. We should also ensure that we take opportunities to connect the Native past to the Indigenous present, in ways that go beyond land acknowledgements. Archaeologists can be better allies, accomplices, and co‐conspirators.
Chapter 4 Good Medicine: Prescriptions for Indigenous Archaeological Practice
Authors: Marek‐Martinez Ora , Gonzalez Sara L. 
Published: August 2023

ABSTRACTWhile the history of North American archaeology points to a long engagement with tribal elders and scholars, these encounters largely consist of unequal, extractive relationships wherein Indigenous collaborators and Indigenous archaeologists have been treated more as objects of study and pity—what Bea Medicine refers to as “creatures”—rather than as equal research partners. As an Indigenous woman and a settler Chicanx woman, we reflect on the life journey and scholarship of Bea Medicine, a Lakota scholar‐activist and mentor to Indigenous anthropologists. Dr. Medicine's work has provided generations of Indigenous anthropologists with the means to participate in the discipline with their whole selves and, importantly, on their own terms. We argue that Medicine's contributions provide good medicine for the field in the form of concrete strategies for continuing to decolonize the discipline and for doing work that centers the direct needs and perspectives of Indigenous peoples. When read alongside Indigenous archaeologies’ often overlooked grandmothers, mothers, and aunties, Medicine's work also highlights continuing disparities in archaeological practice, from our relationships with and to Indigenous nations to the relations we cultivate in the Academy as Black, Indigenous, and People of Color.
Chapter 5 American Archaeology's Lost Women: Unacknowledged Labor & the Making of Archaeology
Authors: Kirakosian Katie 
Published: August 2023

ABSTRACTWhile work has been done to uncover the roles of female archaeologists who supported their husband's careers with little acknowledgment or support, less work has been done to explore the diversity of hidden women's labor that helped support American archaeology during the nineteenth and early twentieth centuries (Browman 2013; White et al. 1999). Institutions such as Harvard's Peabody Museum of Archaeology and Ethnology and the Robert S. Peabody Institute of Archaeology benefitted early on from countless female staff, including clerks, secretaries, and librarians. This paper seeks to make connections between women's labor in archaeology in the late nineteenth and early twentieth century and adjunct labor in the late twentieth and early twenty‐first century.
Evolution of the neuronal substrate for kin recognition in social Hymenoptera
Authors: Couto Antoine , Marty Simon , Dawson Erika H. , d'Ettorre Patrizia , Sandoz Jean‐Christophe , Montgomery Stephen H. 
Published: August 2023

ABSTRACTIn evolutionary terms, life is about reproduction. Yet, in some species, individuals forgo their own reproduction to support the reproductive efforts of others. Social insect colonies for example, can contain up to a million workers that actively cooperate in tasks such as foraging, brood care and nest defence, but do not produce offspring. In such societies the division of labour is pronounced, and reproduction is restricted to just one or a few individuals, most notably the queen(s). This extreme eusocial organisation exists in only a few mammals, crustaceans and insects, but strikingly, it evolved independently up to nine times in the order Hymenoptera (including ants, bees and wasps). Transitions from a solitary lifestyle to an organised society can occur through natural selection when helpers obtain a fitness benefit from cooperating with kin, owing to the indirect transmission of genes through siblings. However, this process, called kin selection, is vulnerable to parasitism and opportunistic behaviours from unrelated individuals. An ability to distinguish kin from non‐kin, and to respond accordingly, could therefore critically facilitate the evolution of eusociality and the maintenance of non‐reproductive workers. The question of how the hymenopteran brain has adapted to support this function is therefore a fundamental issue in evolutionary neuroethology. Early neuroanatomical investigations proposed that social Hymenoptera have expanded integrative brain areas due to selection for increased cognitive capabilities in the context of processing social information. Later studies challenged this assumption and instead pointed to an intimate link between higher social organisation and the existence of developed sensory structures involved in recognition and communication. In particular, chemical signalling of social identity, known to be mediated through cuticular hydrocarbons (CHCs), may have evolved hand in hand with a specialised chemosensory system in Hymenoptera. Here, we compile the current knowledge on this recognition system, from emitted identity signals, to the molecular and neuronal basis of chemical detection, with particular emphasis on its evolutionary history. Finally, we ask whether the evolution of social behaviour in Hymenoptera could have driven the expansion of their complex olfactory system, or whether the early origin and conservation of an olfactory subsystem dedicated to social recognition could explain the abundance of eusocial species in this insect order. Answering this question will require further comparative studies to provide a comprehensive view on lineage‐specific adaptations in the olfactory pathway of Hymenoptera.
