Authors: Ülker Pembe , Ülker Mustafa , Karamustafa Kurtuluş 
Published: May 2022

PurposeThis study aims to contribute to the relevant body of knowledge by examining the bibliometric studies related to tourism and hospitality indexed in the Web of Science (WoS) database from a bibliometric perspective (evaluative and relational techniques).Design/methodology/approachThe WoS database was used to obtain studies to be reviewed. A total of 136 studies were analyzed and visualized in terms of evaluative and relational techniques, and a subject categorization was made.Findings“Tourism management” and “tourism and hospitality” are the two fields of research where bibliometric studies are carried out more frequently. Evaluative techniques were used in most studies while relational techniques, such as co-word, co-author, co-citation analysis and bibliographic coupling, were performed less. Relational techniques indicate that the words “bibliometric analysis” and “tourism” are frequently used together in the studies examined; the most common authorship cooperation is between China and USA.Research limitations/implicationsThis study provides an overview of bibliometric studies in tourism and hospitality literature. It expands the previous literature and shows study topics that are more focused by examining the abstracts and contents of articles published in journals in different WoS categories.Practical implicationsFindings related to evaluative and relational techniques can serve as useful information for researchers, who are new to the field.Originality/valueThis study contributes to the current knowledge accumulation by its lack of year, country, region and language limits.

Three-dimensional printing technologies for dental prosthesis: a review
Authors: Alageel Omar 
Published: May 2022

Purpose
Three-dimensional (3D) printing technologies have gained attention in dentistry because of their ability to print objects with complex geometries with high precision and accuracy, as well as the benefits of saving materials and treatment time. This study aims to explain the principles of the main 3D printing technologies used for manufacturing dental prostheses and devices, with details of their manufacturing processes and characteristics. This review presents an overview of available 3D printing technologies and materials for dental prostheses and devices.

Design/methodology/approach
This review was targeted to include publications pertaining to the fabrication of dental prostheses and devices by 3D printing technologies between 2012 and 2021. A literature search was carried out using the Web of Science, PubMed, Google Scholar search engines, as well as the use of a manual search.

Findings
3D printing technologies have been used for manufacturing dental prostheses and devices using a wide range of materials, including polymers, metals and ceramics. 3D printing technologies have demonstrated promising experimental outcomes for the fabrication of dental prostheses and devices. However, further developments in the materials for fixed dental prostheses are required.

Originality/value
3D printing technologies are effective and commercially available for the manufacturing of polymeric and metallic dental prostheses. Although the printing of dental ceramics and composites for dental prostheses is promising, further improvements are required.
A commentary on the “new” institutional actors in sustainability reporting standard-setting: a European perspective
Authors: Giner Begoña , Luque-Vílchez Mercedes 
Published: May 2022

Purpose
The purpose of this paper is to discuss the progress and future prospects of two relatively “new” institutions in this field: the European Commission (EC), together with the European Financial Reporting Advisory Group (EFRAG), and the International Financial Reporting Standards (IFRS) Foundation.

Design/methodology/approach
This paper reflexively analyses the recent events that characterise the European Union (EU) regulatory standard-setting landscape in the sustainability field. It is mainly based on publicly available documents.

Findings
After analysing the different routes followed to enter the field, this paper shows how the EC/EFRAG takes a wider view than the IFRS Foundation on certain key reporting aspects, that is, target audience, materiality and reporting boundary. As for the reporting scope, although it seems that the IFRS Foundation has a more restrictive vision, it is working to broaden it.

Practical implications
This paper provides some ideas about the potential cooperation between the two institutions. This paper also highlights some potential problems stemming not only from their intrinsic characteristics but also from the routes they have taken to enter the field.

Social implications
By envisioning how the EU sustainability reporting standard-setting landscape might evolve, this paper sheds light on how companies might need to approach sustainability reporting to adapt to the new institutional demands. Suggestions for collaboration between the two institutions could help them reach common ground and, thus, prevent misunderstandings for companies and stakeholders.

Originality/value
The reflections and takeaways benefit from the authors’ first-hand information, as both are involved in the EU process. The authors could, therefore, feed into further discussions on the developments and challenges facing the EU in this domain.
Soil biota is decisive for overyielding in intercropping under low phosphorus conditions
Authors: Qiao Xu , Bei Shuikuan , Wang Guangzhou , Li Chunjie , Li Haigang , Zhang Junling , Zhang Fusuo 
Published: May 2022

Abstract

Cereal/legume intercropping typically increases crop yield; however, the mechanisms through which soil microbes mediate overyielding in intercropping under different nutrient availability remain elusive.

Here we examined the effect of soil biota and phosphate (P) availability on intercropping advantages in wheat Triticum aestivum/faba bean Vicia faba systems using a pot experiment consisting of soil sterilization treatment and different P supply levels. A complementary experiment on the contribution of different microbial groups was also included using the removal method.

Intercropping advantage was observed only in the presence of microbes and was mainly associated with increase in wheat biomass. Overyielding effect was stronger under low‐P than high‐P conditions, and was negatively correlated with P availability and the effect of soil biota in the monoculture. The effect was likely related to the enlarged active P pools and modified microbial communities associated with the alteration of rhizosphere traits (protons and carboxylates) by the neighbouring faba bean. Similarly, simplification of soil microbes significantly increased the growth and P uptake of wheat plants while faba bean growth was less affected.

Synthesis and applications. Our research provides compelling evidence that soil microbiome is important in driving intercropping overyielding by regulating interspecific interactions under nutrient‐limited conditions. These findings have important implications for crop species choice in designing and managing intercropping systems where crop functional traits, soil microbiome and nutrient management should be integrated in pursuit of sustainable agriculture.
Oyster larvae swim along gradients of sound
Authors: Williams Brittany R. , McAfee Dominic , Connell Sean D. 
Published: May 2022

Abstract

Marine soundscapes provide navigational information for dispersing organisms, but with wide‐scale habitat loss, these soundscapes are becoming muted. Consequently, dispersing larvae that use soundscapes for navigation may be lost at sea, limiting the success of restoration efforts that rely upon the recruitment of dispersing organisms to restore habitat. Where limited larval supply constrains restoration efforts, using speakers to create gradients in healthy soundscapes could provide the navigational cue that attract larvae and enhances recruitment.

Combining laboratory and field studies, we test whether broadcasting soundscapes might act as a directional cue for oysters targeted for national‐scale reef restoration; the Australian flat oyster Ostrea angasi. In the laboratory, we tested whether settlement of larvae increases along a gradient of increasing sound intensity (8 m laboratory tank) versus a no sound control, and whether settlement increases with soundscapes that approximate healthy reefs.

In the field, we tested the context dependency and magnitude of using boosted soundscapes for restoration practice in areas of low, medium and high background noise, by observing the settlement rates of naturally recruiting oysters at three restoration sites when exposed to boosted reef sound relative to ambient conditions.

In the laboratory, we showed that 83% of larvae swim horizontally towards reef sound to settle in greater densities closer to its source, a near doubling of the larvae (44%) that dispersed in the no sound controls. Larval settlement increased by 300% in the presence of reef sound relative to controls in the laboratory. In the field, speakers increased larval settlement in localities of lower background noise. To our knowledge, this is the first evidence that oyster larvae can swim horizontally and choose to move towards a sound source.

Synthesis and applications. We discovered that oyster larvae can swim horizontally towards reef sound and then settle in higher densities, relative to controls. Importantly, this effect of sound on recruitment is enhanced in localities of lower background noise. We propose that where recruitment is limited, restoration practitioners best use acoustic technology in localities of lower background noise to guide larvae to boost recovery.
Review: Genetic structure and local adaptation in natural forests of Cryptomeria japonica
Authors: Tsumura Yoshihiko 
Published: May 2022

AbstractCryptomeria japonica is a very important and useful forestry tree in Japan and there are vast areas of plantation area that occupy 44% of the total man‐made forest in the country. Natural populations have declined as a result of logging and overexploitation for more than a thousand years. The natural distribution of C. japonica is from Aomori Prefecture to Kagoshima Prefecture and it has adapted to widely different environments in Japan. In China, the variety C. japonica var. sinensis is distributed. The genetic diversity is higher in Japanese Cryptomeria than in the Chinese variety, and within Japan, western populations have higher genetic diversity than northern populations. Genetic structure of C. japonica within Japan was clear, with isolation by distance (IBD), and the omote‐sugi on the Pacific Ocean side and ura‐sugi group on the Sea of Japan side were clearly separated by STRUCTURE analysis. Genetic structure was also clear in the Chinese population but there was no IBD, which suggested considerable human disturbance in the past. Local adaption is apparent in this species, in, for example, morphological traits among the three groups such as omote‐sugi, ura‐sugi, and Chinese population. The time of divergence among the three groups was at least before last glacial maximum. Global climate change largely affects species distributions and local adaptation, which play important roles in adaptation and speciation. A suitable conservation strategy for natural populations of C. japonica is ex situ conservation of large trees and applying a zoning method to the remaining natural forests.
Introduction: On irreconciliation
Authors: Mookherjee Nayanika 
Published: May 2022

AbstractMost post‐conflict reconciliatory exercises make it incumbent upon survivors to forgive, and seek closure as a demonstration of ‘moving on’. Various anthropologists have criticized reconciliation and related forms of ‘alternative justice’ extensively but within the framework of maintaining social bonds and the rule of law. In this introduction, I reflect critically on the interdisciplinary scholarship on reconciliation, apology, and forgiveness, and theorize irreconciliation as a less examined lens of analysis. Rather than being in opposition to ‘peace’, irreconciliation allows us to interrogate the status quo by refusing to forgive endemic impunities, particularly in the aftermath of staged processes of justice and the absence‐presence of the rule of law. In this special issue of theJRAI, I ethnographically explore irreconciliation's links with law, aesthetics, temporality, resistance, and control to locate its multiple analytical manifestations. Irreconciliation allows an important examination of the rule of law within processes of unresolved genocidal injustices and debates relating to slavery, Black Lives Matter, and institutional responses.
Evaluation of extraction parameters in authentic hair reference material using statistical design of experiments
Authors: Spear Brianna , DeCaprio Anthony P. 
Published: May 2022

AbstractOptimal methods for forensic hair analysis are often debated, especially regarding extraction parameters that include incubation time, temperature, and size of extracted hair particles. To assess hair pretreatment parameters for analysis of drugs of abuse, the statistical technique known as Design of Experiments (DoE) is useful. DoE evaluates both the individual roles and the combinatorial associations between multiple variables and overall drug extraction efficiency. Previous reports have focused on incorporated hair reference material (HRM), which is prepared in the lab at a specified drug concentration. In contrast, authentic HRM, which is prepared by diluting hair from drug users with blank hair to achieve specific drug concentrations, is an effective matrix for standardization of forensic hair testing, since the drug is incorporated into the hair matrix via uptake from systemic distribution. In the present study, extraction parameters for authentic HRM samples containing multiple drugs (diazepam, alprazolam, cocaine, methamphetamine, oxycodone, hydrocodone, and morphine) and metabolites (nordiazepam, cocaethylene, norcocaine, hydroxycocaine, and 6‐monoacetylmorphine) were optimized based on recovery using a 23 full factorial DoE matrix. The factors evaluated included extraction solvent volume/sample weight ratio (12.5 or 25 μL/mg), particle size (pulverized or cut into 1 mm snippets), and extraction time (2 or 24 h) using solvent swelling. DoE analysis revealed significant differences in the optimal combinations of extraction parameters for maximum recovery. However, for the majority of drugs and metabolites, the most effective extraction method consisted of pulverizing hair prior to a 2‐h extraction with a 12.5 μL/mg extraction solvent volume/sample weight ratio.
Insect diversity and succession patterns on pig cadavers in Changwon, South Korea

Published: May 2022

AbstractSuccession patterns spanning three seasons for insect fauna on pig cadavers were studied in Changwon, South Korea in 2018 and 2019. A total of 107 species belonging to 41 families in six orders were collected and identified. Four decomposition stages were recognized: fresh, bloated, decay, and dry. The number of species increased significantly after the fresh stage and reached the maximum number by the decay stage. The sequence of insect succession followed a general pattern in which Diptera peaked initially and Coleoptera peaked later.Chrysomya pinguiswas the most frequently present species, and the timing of its different developmental stages on cadavers could be the most important indicator for post‐mortem interval estimations in Changwon. Spatial and seasonal differences in the richness of insects were not significant. However,Calliphora nigribarbisoccurred exclusively in spring and autumn, andPheropsophus javanusoccurred exclusively in one locality. Therefore, these species may be important for characterizing the different seasons or locations during post‐mortem interval estimations. A list of the insects associated with above‐ground pig cadavers during the three seasons was compiled, and it may be useful for estimating the time since death in areas with a similar bioclimate.

Published: May 2022

SummaryBackgroundGut‐directed hypnotherapy improves symptoms for patients with irritable bowel syndrome (IBS). Group hypnotherapy, as well as hypnotherapy administered by nurses, can increase treatment availability, but there are few comparisons between individual and group‐based hypnotherapy.AimWe aimed to evaluate and compare the effectiveness of nurse‐administered hypnotherapy for IBS delivered individually or in groups.MethodsIBS patients were randomised to individual or group hypnotherapy (8 sessions, 12 weeks). The primary endpoint was changes in severity of IBS symptoms. A responder was defined as reduction of IBS severity scoring system (IBS‐SSS) ≥50 points at the end of treatment compared to baseline. The effects on extracolonic and psychological symptoms, and quality of life were also assessed. Symptoms were also followed up 6 months after treatment start.ResultsA total of 119 patients were randomised (61 individual, 58 group hypnotherapy). Patients reported improvements in IBS symptoms (IBS‐SSS) (individual: 332 (273–401) (median, IQR), versus 216 (140–308), (p < 0.0001), group: 315 (239–382), versus 217 (149–314), (p < 0.0001)), with no differences between the groups (p = 0.16). Extracolonic symptoms, psychological symptoms and quality of life also improved, without clear differences between the groups. Sixty‐nine percent of the individual hypnotherapy patients were responders after treatment versus 57% of the group hypnotherapy patients (p = 0.25). Symptom improvements were also seen at follow‐up.ConclusionsNurse‐administered gut‐directed hypnotherapy, delivered individually or in groups, relieves IBS symptoms, improves psychological symptoms and quality of life. Group hypnotherapy can be an efficacious alternative, enabling more patients to benefit from the treatment (ClinicalTrials.gov ID no of study: NCT03432078).

Published: May 2022

SummaryBackgroundInflammatory bowel disease (IBD) is a chronic inflammatory immune‐mediated disorder of the gut with frequent extra‐intestinal complications. Pancreatic involvement in IBD is not uncommon and comprises a heterogeneous group of conditions, including acute pancreatitis (AP), chronic pancreatitis (CP), autoimmune pancreatitis (AIP) and pancreatic exocrine insufficiency (PEI); however, data on such an association remain sparse and heterogeneous.MethodPubMed/MEDLINE and EMBASE databases were searched for studies investigating pancreatic involvement in patients with IBD.ResultsFour thousand one hundred and twenty‐one records were identified and 547 screened; finally, 124 studies were included in the review. AP is the most frequent pancreatic manifestation in IBD; the majority of AP cases in IBD are due to gallstones and drugs but cases of idiopathic AP are increasingly reported. AIP is a rare disease, but a strong association with IBD has been demonstrated, especially for type 2 and ulcerative colitis. The pathogenetic link between IBD and AIP remains unclear, but an immune‐mediated pathway seems plausible. An association between CP and PEI with IBD has also been suggested, but data are to date scarce and conflicting.ConclusionThis is the first systematic review of the association between IBD and pancreatic diseases. Gallstones and drugs should be considered the most probable causes of AP in IBD, with type 2 AIP also being possible.
Infant behavioural effects of smartphone interrupted parent‐infant interaction
Authors: Tidemann Ida T. , Melinder Annika M. D. 
Published: May 2022

AbstractInfants are vulnerable to changes in the dyadic synchrony with their caregivers, as demonstrated in numerous experiments employing the still‐face paradigm. The sudden lack of attunement causes infant stress reactions and the still‐face literature have suggested potential long‐term costs of this in terms of development of social, emotional and cognitive skills. Acknowledging the rapid technological development accompanied by altered practices in the parent‐infant interaction, the current study investigates infant behavioural reactions in a similar experimental paradigm, manipulating parental responsiveness and sensitivity in a slightly different manner. In the current study, the parent interrupts the ongoing interaction, simulating occupation with a smartphone, rather than making a ‘still‐face’. In a cross‐sectional design, infants of six, nine and twelve months display increased levels of protest behaviour in response to the interrupted interaction with their parent, together with lowered levels of positive engagement and social monitoring, suggesting similar behavioural responses as the still‐face effect. Implications for infant social and emotional development, as well as for mindful tech habits are discussed.
Re‐imaging everyday routines and educational aspirations under COVID‐19 lockdown: Narratives of urban middle‐class children in Punjab, India
Authors: Barn Ravinder , Sandhu Damanjit , Mukherjee Utsa 
Published: May 2022

AbstractBased on in‐depth interviews with 24 middle‐class Indian child participants, this is the first exploratory qualitative study, in India, to demonstrate the ways in which children as reflexive social actors re‐negotiated everyday schedules, drew on classed resources at their disposal and made sense of the impact of the pandemic on their educational pathways and future aspirations. These narratives offer a unique lens on the politics of middle‐classness and its constitutive relation to constructions of normative childhoods in contemporary India. Study findings contribute to the sociology of Indian childhood and more generally help enrich our understanding of southern childhoods and the reproduction of inequalities in contemporary India.
