Authors: Fan Wenjie , Liu Yong , Li Hongxiu , Tuunainen Virpi Kristiina , Lin Yanqing 
Published: October 2021

PurposeDrawing on attribution theory, the current paper aims to examine the effects of review content structures on online review helpfulness, focusing on three pertinent variables: review sidedness, information factuality, and emotional intensity at the beginning of a review. Moreover, the moderating roles of reviewer reputation and review sentiment are investigated.Design/methodology/approachThe review sentiment of 144,982 online hotel reviews was computed at the sentence level by considering the presence of adverbs and negative terms. Then, the authors quantified the impact of variables that were pertinent to review content structures on online review helpfulness in terms of review sidedness, information factuality and emotional intensity at the beginning of a review. Zero-inflated negative binomial regression was employed to test the model.FindingsThe results reveal that review sidedness negatively affects online review helpfulness, and reviewer reputation moderates this effect. Information factuality positively affects online review helpfulness, and positive sentiment moderates this impact. A review that begins with a highly emotional statement is more likely to be perceived as less helpful.Originality/valueUsing attribution theory as a theoretical lens, this study contributes to the online customer review literature by investigating the impact of review content structures on online review helpfulness and by demonstrating the important moderating effects of reviewer reputation and review sentiment. The findings can help practitioners develop effective review appraisal mechanisms and guide consumers in producing helpful reviews.

PurposeMany experts suggest that the human being explore marine resources and marine new energy sources to alleviate the shortage of land resources and the ecological degradation. However, island coastal zones are considered to be fragile ecosystems; their geographical location and natural characteristics, their biodiversity and associated ecosystems, and their exposure to diverse land and sea conditions all make them highly vulnerable to environmental changes and human activities. Therefore, it is necessary to achieve the goals of environmental protection and sustainable development on the basis of a comprehensive evaluation and understanding of islands.Design/methodology/approachDue to the importance of island groups, this paper conducts evaluation studies on them. Using the Delphi, AHP and TOPSIS methods, this study evaluated quantitatively the comprehensive development level and comprehensive development potential of island groups in terms of resources, natural environment, economy and society. Innovatively using them as two subsystems, the present study combined the coupling coordination model and the obstacle factor calculation method.FindingsThe prospective index of comprehensive development was applied to the Changdao Island Group in Yantai, Shandong Province as an example, and the final evaluation revealed that the comprehensive development prospect of this island group had an upward trend from 2010 to 2017. Future efforts should be made to improve its economic and social conditions and economic development status, apart from promoting its comprehensive development by improving human resources management, increasing the GDP growth rate, and improving fresh water and electricity supply.Originality/valueThis study takes the integrated development level of the island and the integrated development potential of the island as two subsystems, and the innovative application of the coupling coordination degree model is used to calculate the integrated development index of the island to understand the development status of the island area. On the basis of this model, the obstacle factor identification method is designed to identify the main obstacle factors, and on the basis of evaluation and identification, specific measures to ensure the sustainable development of the island area are effectively proposed.
Differential response to prey quorum signals indicates predatory specialization of myxobacteria and ability to predate Pseudomonas aeruginosa

Published: October 2021

SummaryMultiomic analysis of transcriptional and metabolic responses from the predatory myxobacteria Myxococcus xanthus and Cystobacter ferrugineus exposed to prey signalling molecules of the acylhomoserine lactone and quinolone quorum signalling classes provided insight into predatory specialization. Acylhomoserine lactone quorum signals elicited a general response from both myxobacteria. We suggest that this is likely due to the generalist predator lifestyles of myxobacteria and ubiquity of acylhomoserine lactone signals. We also provide data that indicates the core homoserine lactone moiety included in all acylhomoserine lactone scaffolds to be sufficient to induce this general response. Comparing both myxobacteria, unique transcriptional and metabolic responses were observed from Cystobacter ferrugineus exposed to the quinolone signal 2‐heptylquinolin‐4(1H)‐one (HHQ) natively produced by Pseudomonas aeruginosa. We suggest that this unique response and ability to metabolize quinolone signals contribute to the superior predation of P. aeruginosa observed from C. ferrugineus. These results further demonstrate myxobacterial eavesdropping on prey signalling molecules and provide insight into how responses to exogenous signals might correlate with prey range of myxobacteria.

Published: October 2021

SummaryHotspots of N2O emissions are generated from legume residues during decomposition. Arbuscular mycorrhizal fungi (AMF) from co‐cultivated intercropped plants may proliferate into the microsites and interact with soil microbes to reduce N2O emissions. Yet, the mechanisms by which or how mycorrhizal hyphae affect nitrifiers and denitrifiers in the legume residues remain ambiguous. Here, a split‐microcosm experiment was conducted to assess hyphae of Rhizophagus aggregatus from neighbouring maize on overall N2O emissions from stubbles of nodulated or non‐nodulated soybean. Soil microbes from fields intercropped with maize/soybean amended with fertilizer nitrogen (SS‐N1) or unamended (SS‐N0) were added to the soybean chamber only. AMF hyphae consistently reduced N2O emissions by 20.8%–61.5%. Generally, AMF hyphae promoted the abundance of N2O‐consuming (nosZ‐type) denitrifiers and altered their community composition. The effects were partly associated with increasing MBC and DOC. By contrast, AMF reduced the abundance of nirK‐type denitrifiers in the nodulated SS‐N0 treatment only and that of AOB in the non‐nodulated SS‐N1 treatment. Taken together, our results show that AMF reduced N2O emissions from soybean stubbles, mainly through the promotion of N2O‐consuming denitrifiers. This holds promise for mitigating N2O emissions by manipulating the efficacious AMF and their associated microbes in cereal/legume intercropping systems.
The Electrical Contractors Case: Irish Supreme Court Illuminates Collective Bargaining and Delegated Legislation
Authors: Eustace Alan 
Published: October 2021

AbstractAs Europe begins to emerge from the Covid‐19 pandemic, two trends are clear: one, labour market reform is urgently needed, to cope with new economic and technological realities; and two, big government is back. The recent decision of the Irish Supreme Court in Náisiúnta Leichtreach Contraitheoir Éireann v Labour Court illuminates the relationship between collective bargaining and the regulatory state. In potentially one of the most important decisions in Irish labour law in decades, the Court rejected a constitutional challenge to legislation aimed at empowering social partners to regulate economic sectors through collective bargaining. This article situates that decision within recent scholarship on the ‘labour constitution’ model of labour law, under which the social partners should participate in economic governance. It also highlights the relevance of the decision for the ‘Social Europe’ agenda and the political economy of both national constitutional law and the EU internal market.

AbstractBackgroundRecurrent abdominal pain in the emergency department (ED) might represent an opportunity for screening of depression and/or anxiety.MethodsWe systematically searched five databases for studies evaluating the effect of screening for depression and/or anxiety in ED patients with recurrent and undifferentiated abdominal pain. Given paucity of direct evidence, we also searched for indirect evidence including studies that assessed prevalence of depression and/or anxiety in EDs (not necessarily recurrent abdominal pain), diagnostic accuracy of screening tools, effectiveness of screening in other settings, and outcomes such as repeat ED visits of patients with abdominal pain who were screened in the ED. Two methodologists evaluated certainty in the evidence using the GRADE approach.ResultsA total of 4,337 citations were reviewed, and zero studies were found on the effect of screening in patients with recurrent and undifferentiated abdominal pain in the ED. A total of 35 studies were included as relevant indirect evidence. In studies of ED patients with abdominal pain, depression ranged from 10% to 29%, while anxiety ranged from 18% to 50%. False positives appear to be an issue given relatively low specificity of screening tools. One randomized trial including ED patients with vague symptoms evaluated the effect of depression screening on a composite outcome of depression recognition, psychiatric consultation, or referral by the emergency physician (risk ratio = 1.49, 95% confidence interval [CI] = 0.49 to 4.53, very low certainty). One study reported that patients with undifferentiated abdominal pain who screened positive for depression have had increased ED recidivism (odds ratio = 3.17, 95% CI = 1.14 to 8.85, very low certainty).ConclusionsWe were unable to identify any evidence that confirms that depression or anxiety screening in ED patients with recurrent and undifferentiated abdominal pain improves outcomes or changes management downstream.

AbstractBackgroundAppendiceal neurendocrine tumours (NETs) are rare neoplasms and diagnosis is commonly incidental following appendectomy. We aimed to review our experience with appendiceal NETs.MethodsRecords of children with appendiceal NETs were reviewed and data concerning demographic characteristics, clinical findings, surgical procedures, histopathological findings, management and outcomes were recorded.ResultsBetween 1985 and 2021, 33 cases with appendiceal NETs (median age 11.8 years, range 7.8–16; male/female = 10/23) were identified. All but one patients presented with abdominal pain, six had vomiting, four had fever and they underwent appendectomies with presumed diagnosis of acute appendicitis. Abscess drainage and appendectomy was performed in a 16‐year‐old girl for suspected right ovarian mass, and tumour was positive in the omentum. Histopathological diagnosis was classical carcinoid tumour (NET) in all cases. Median tumour size was 0.9 cm (n = 26, range, 0.1–3.5 cm); tumours were ≤1 cm in 19 cases, 2 cm in one, 3.5 cm in another case. Tumours were located in the tip (n = 11), body (n = 6) and base of appendix (n = 1) (in others data unavailable). In 28 patients with data, tumour extended to submucosa in five, to tunica muscularis in seven, to subserosa in six, to serosa in six, to mesoappendix in three, to periappendiceal fat in one. Three cases were lost to follow‐up, 31 cases were alive (median follow‐up 53 months).ConclusionsPaediatric appendiceal NETs do not behave aggressively and appendectomy alone is sufficient for tumours ≤2 cm regardless of local invasion. The need for further extensive surgery in tumours >2 cm also remains controversial.

Published: October 2021

AbstractPurposeTo compare the refractive outcome and residual accommodation with respect to various degrees of iris and skin pigmentation in hypermetropic children using 2 drops of cyclopentolate 1% (C + C) or 1 drop of cyclopentolate 1% and 1 drop of tropicamide 1% (C + T).MethodsTwo hundred fifty‐one hypermetropic children were classified according to iris and skin pigmentation (light, medium, dark) and received randomized and double‐blind C + C or C + T. Refractive error (spherical equivalent, SEQ) was determined using the Retinomax‐K + 3. In 204 subjects, residual accommodation (RA) was determined using the PlusoptiX PowerRefractor.ResultsA linear mixed model with a light‐irided and light skin‐pigmented reference group receiving C + T (mean SEQ +3.10 ± 1.87D) indicated significant less hypermetropia in subjects with a dark iris having a medium‐ and dark‐pigmented skin in C + T, −1.02 ± 0.29 (−1.59/−0.45) and −1.53 ± 0.30 (−2.10/−0.95); and in subjects having a light‐, medium‐ and dark‐pigmented skin in C + C, −0.74 ± 0.34 (−1.41/−0.06), −1.26 ± 0.30 (−1.85/−0.66) and −1.84 ± 0.30 (−2.42/−1.26). Similar findings were present for RA. Our model with a light‐irided and light skin‐pigmented reference group receiving C + T (mean RA +0.84 ± 0.61D) indicated significantly higher RA in dark‐irided subjects with medium‐ and dark‐pigmented skin in C + T, +1.05 ± 0.19 (+0.67/+1.43) and +1.35 ± 0.20 (+0.9/+1.74), and in C + C, +1.13 ± 0.21 (+0.71/+1.55) and +1.90 ± 0.19 (+1.51/+2.28).ConclusionsWe found solid evidence that skin pigmentation rather than iris pigmentation is the decisive factor for effectiveness of cycloplegics. Awareness of the limitations of cycloplegic regimens in dark‐irided/pigmented children is needed. Our study showed that cyclopentolate 1% combined with tropicamide 1% provides more accurate refractive outcomes both statistically and clinically integrating the factor skin pigmentation for dark‐irided subjects.

Published: October 2021

SummaryIt is unclear whether elderly patients established on direct oral anticoagulants (DOACs) have greater exposure to these drugs, which could subsequently increase their risk of bleeding. We assessed DOAC exposure and factors affecting it in a real‐world elderly cohort of patients. For this, 151 medically stable hospital inpatients (76 established on apixaban, 61 on rivaroxaban, 14 on dabigatran) with a median [interquartile range (IQR)] age of 84 (78–89) years were recruited. Patients provided blood samples for measurement of peak and trough plasma DOAC concentrations. There was up to 48‐fold and 13‐fold variation in trough and peak plasma drug concentrations respectively. A significantly greater proportion of patients on apixaban had peak plasma drug concentrations within the reported ranges compared to those on either rivaroxaban or dabigatran (82·9% vs. 44·3% vs. 64·3% respectively; P < 0·001). A third of the variability in DOAC plasma concentrations was attributed to the influences of DOAC dosage, renal function and gender. To what extent the observed increases in DOAC exposure in the older patients is the cause of their increased risk of bleeding, which could potentially be ameliorated by dosing titration, requires further investigation.
Research on professional organizations: A review of theoretical traditions, themes, methods and locations
Authors: Brock David M. 
Published: October 2021

AbstractThis research note presents an overview of the contemporary “professional organization” research area. We begin with the historical roots and evolution of research into professionals and the organizations in which they work, identifying five theoretical traditions—namely sociology of organization, sociology of the professions, professional organization, professional service firms, and public professionalism. Reviewing recent research in these areas allows us to identify important research phenomena—such as hybridity, institutional work, internationalization, and professional identity—and to understand how the institutional view within the “sociology of the professions” tradition has become a dominant paradigm for this research. This review also reveals the extent to which various occupations, methodological approaches, and academic fields, and locations have assumed positions of importance in recent years. Finally, future directions relevant to sociology researchers are discussed.

AbstractAimsMicroglia‐mediated neuroinflammation plays an important role in the pathological process of ischemic stroke, and the effect of imperatorin on post‐stroke neuroinflammation is not fully understood.MethodsPrimary microglia were treated with imperatorin for 2 h followed by LPS (100 ng/ml) for 24 h. The expression of inflammatory cytokines was detected by RT‐PCR, ELISA, and Western blot. The activation of MAPK and NF‐κB signaling pathways were analyzed by Western blot. The ischemic insult was determined using a transient middle cerebral artery occlusion (tMCAO) model in C57BL/6J mice. Behavior tests were used to assess the neurological deficits of MCAO mice. TTC staining was applied to measure infract volume.ResultsImperatorin suppressed LPS‐induced activation of microglia and pro‐inflammatory cytokines release and attenuated ischemic injury in MCAO mice. The results of transcriptome sequencing and Western blot revealed that downregulation of MAPK and NF‐κB pathways might contribute to the protective effects of imperatorin.ConclusionsImperatorin downregulated MAPK and NF‐κB signaling pathways and exerted anti‐inflammatory effects in ischemic stroke, which indicated that imperatorin might be a potential compound for the treatment of stroke.
Why do animal groups matter for conservation and management?
Authors: Maldonado‐Chaparro Adriana A. , Chaverri Gloriana 
Published: October 2021

AbstractThe internationally recognized levels of conservation, namely ecosystems, species, and genes, have thus far served as important guidelines to determine how national and international laws should protect nature. However, a far ignored aspect of a species' life history in the legislation is its tendency to form social groups. Group members greatly depend on each other for survival and reproduction, and when the persistence of groups is threatened, so may the population as a whole. Humans affect groups through indirect activities, such as tourism, or directly by removing individuals through poaching, for example. These activities disturb groups in both predictable and unpredictable ways: destabilizing dominance hierarchies, changing the strength of social relationships, modifying cooperative interactions, reducing alloparental care, and altering social skills, among others. We propose that greater efforts must be undertaken first, to more thoroughly understand how our actions are affecting group dynamics in as many species as possible, and second, to adapt policies to reduce the negative effects of direct and indirect anthropogenic activities on group and population persistence.

Published: October 2021

SummaryBackgroundInpatient care in Germany has been subject to change since the introduction of the DRG‐based payment system. There have been no publications on important differentiating factors such as the spectrum of care and the staffing situation in dermatology.MethodsHealth care analysis of 115 dermatology hospitals in October 2019 using a structured survey questionnaire.ResultsOn average, the spectrum of care included 31.0 % general dermatology, 33.6 % surgical dermatology, 15.6 % oncology, and 10.1 % allergology. The clinics had an average of 14 full‐time positions and 3 part‐time positions (university clinics: 23/5, non‐university clinics: 9/2). The mean nationwide proportion of women in the physician teams showed the following distribution: postgraduate physicians 73.3 %, senior physicians 53.0 %, directors 20.0 %. The applicant situation of senior physicians and specialists was assessed as predominantly poor, that of residents as predominantly good. Worse applicant situations were present in non‐university hospitals and in rural areas. The satisfaction of the medical directors with the current conditions of inpatient care showed a variable assessment independent of university hospital and non‐university hospital status. However, the threat to inpatient care was predominantly assessed as low (71.6 %).ConclusionsThe overall situation of inpatient dermatological care can be classified as predominantly good. In addition, the majority of dermatology clinics provide a wide range of care with regard to the variety of indications. The general conditions, which in some cases are rated as inadequate, require further measures.
