The moderating effect of movie production efficiency on the relationship between eWOM and review helpfulness
Authors: Lee Sangjae , Choeh Joon Yeon 
Published: August 2020

Purpose
This paper aims to intend to study the effect of movie production efficiency on eWOM and the moderating effect of efficiency on the relationship between eWOM and review helpfulness for movies.

Design/methodology/approach
Production efficiency is suggested by comparing the power of movie resources (e.g. the power of actors, directors, distributors, production companies) against box-office revenue through a data envelopment analysis (DEA).

Findings
The study results present that the number of reviews, the number of reviews by reviewers and review extremity are greater in an efficient subsample than in an inefficient subsample. For efficient movies, the review depth and the strength of the sentiments in the reviews are more positively related to review helpfulness. The prediction results for review helpfulness using the k-nearest neighbor method and automatic neural networks show that the efficient subsample provides a significantly lower prediction error rate than the inefficient subsample. The study results can support the effective facilitation of helpful online movie reviews.

Originality/value
As the numbers of online reviews are increasingly used to provide purchase decision support, it becomes crucial to understand which attributes represent average helpful reviews for movies. While previous studies have examined eWOM (online word-of-mouth) variables as predictors of helpfulness on movie websites, the role of the production efficiency of movies has not been examined considering the relationship between eWOM and review helpfulness for movies.

Interorganizational learning: a strategic framework for service networks
Authors: Peronard Jean-Paul 
Published: August 2020

Purpose
The purpose of this paper is to understand the link between the organizing of service networks and interorganizational learning strategies.

Design/methodology/approach
By deepening the conceptual understanding of service networks and their central properties, an overview of the learning challenges for improved performance is provided. The implications of learning are then discussed using four conceptual types to advance our understanding of learning in various service networks. Two different frameworks are combined, one designed to analyze the properties of service delivery and the other to understand their interorganizational learning implications for different types of service networks.

Findings
This paper examines the central properties of service network delivery and explains their implications for interorganizational learning strategy operationalized in a service network typology.

Practical implications
The proposed framework deepens the understanding of the concept of service networks and brings attention to properties that have implication for interorganizational learning. Knowing the central properties in detail and their major organizing challenges allows for learning strategies to improve service network performance.

Originality/value
The value lies in the deepening the understanding of interorganizational learning in service networks, which is much needed in the growing body of literature on both concepts.
Sustainable development and the circular economy in Greece: case examples from Costa Navarino and Grecotel
Authors: Khodaiji Justin Darayus , Christopoulou Dimitra 
Published: August 2020

Purpose
This paper aims to identify and analyse sustainable development in the Greek hospitality industry. Drawing on an evaluation of two leading hotel groups in Greece, TEMES S.A. and Grecotel Hotels and Resorts and their respective landmark hotels Costa Navarino and Grecotel (Lux Me) Rhodos, the authors focussed on the role that the United Nations (UN) Sustainable Development Goals (SDGs) have played in the industry and in a country heavily reliant on its tourism industry. Additionally, this paper examines and assesses the concepts of the triple bottom line and the circular economy and suggests practical approaches by which hotels may achieve sustainability. The recommendation relies on the belief that the two concepts are interconnected in tackling and achieving a successful vision of the future of sustainability through until 2030.

Design/methodology/approach
The case study focus with regard to the two hotel groups relied heavily on their respective 2018 sustainability reports. Additionally, further secondary research was conducted via several journal databases from 2013 to 2020. Third-party sites were also leveraged including the UN and Forbes.

Findings
It is evident that hotel companies often highlight their sustainability programmes online so that they are accessible to consumers and other stakeholders – including investors. This enables companies to create and close business loops in innovative ways. Their actions on sustainable development help the local economy and in turn help the country. This paper showcases examples of two leading Greek hotel groups, TEMES and Grecotel already working towards a more sustainable operating future.

Originality/value
In spite of research that was limited to secondary sources, the topic of sustainability in Greece is of great value as it is yet to be fully explored. This paper does yield some practical insights that will be of interest to the industry as to how to use the UN’s SDGs as pathway drivers for a successful circular economy.

AbstractThe concentrations of lead (Pb), barium (Ba), and antimony (Sb), characteristic of GSR, were determined in soil sediments and immature (larvae) of cadaveric flies of the family Calliphoridae, by inductively coupled plasma mass spectrometry (ICP‐MS). This research refers to a case study from two real crime scenes in which the corpses were in an advanced state of decomposition. In case 1, the victim had holes similar to gunshot wounds, and in case 2, there was no evidence of perforations in the corpse. Soil sediment collection was performed at three different points of the terrain, at a minimum distance of 10 m from the corpse, for cases 1 and 2. In relation to the collection of immatures, larvae were collected in regions of the mouth, nose, and orifices similar to the entry of firearms projectile into the body, for case 1, and collection of larvae and pupae, located on the body and underneath it, for case 2. It was possible to detect and quantify the three elements of interest (Pb, Ba, and Sb) by ICP‐MS in both sediment and cadaveric larvae. Concentrations of 4.44, 8.74, and 0.08 μg/g were obtained for Pb, Ba, and Sb, respectively, in the soil for case 1. For the case 2, the concentrations in Pb, Ba, and Sb were from 16.34 to 26.02 μg/g; from 32.64 to 57.97 μg/g and from 0.042 to 0.30 μg/g, respectively. In the larvae, Pb, Ba, and Sb were quantified in cases 1 and 2 with a concentration of 6.28 and 1.78 μg/g for Pb, 1.49 and 2.94 μg/g for Ba, 0.50 μg/g and <LD for Sb, respectively. These new results present the detection of characteristic elements of GSR in cadaveric larvae in humans in a real crime scene, besides highlighting the importance of the study of immature flies, using the ICP‐MS technique in forensic analysis.

Published: August 2020

AbstractThe immune interactions occurring between parasitoids and their host insects, especially inDrosophila–wasp models, have long been the research focus of insect immunology and parasitology. Parasitoid infestation inDrosophilais counteracted by its multiple natural immune defense systems, which include cellular and humoral immunity. Occurring in the hemocoel, cellular immune responses involve the proliferation, differentiation, migration and spreading of host hemocytes and parasitoid encapsulation by them. Contrastingly, humoral immune responses rely more heavily on melanization and on the Toll, Imd and Jak/Stat immune pathways associated with antimicrobial peptides along with stress factors. On the wasps’ side, successful development is achieved by introducing various virulence factors to counteract immune responses ofDrosophila. Some or all of these factors manipulate the host's immunity for successful parasitism. Here we review current knowledge of the cellular and humoral immune interactions betweenDrosophilaand its parasitoids, focusing on the defense mechanisms used byDrosophilaand the strategies evolved by parasitic wasps to outwit it.

Published: August 2020

SummaryPlant rhizosphere soil houses complex microbial communities in which microorganisms are often involved in intraspecies as well as interspecies and inter‐kingdom signalling networks. Some members of these networks can improve plant health thanks to an important diversity of bioactive secondary metabolites. In this competitive environment, the ability to form biofilms may provide major advantages to microorganisms. With the aim of highlighting the impact of bacterial lifestyle on secondary metabolites production, we performed a metabolomic analysis on four fluorescent Pseudomonas strains cultivated in planktonic and biofilm colony conditions. The untargeted metabolomic analysis led to the detection of hundreds of secondary metabolites in culture extracts. Comparison between biofilm and planktonic conditions showed that bacterial lifestyle is a key factor influencing Pseudomonas metabolome. More than 50% of the detected metabolites were differentially produced according to planktonic or biofilm lifestyles, with the four Pseudomonas strains overproducing several secondary metabolites in biofilm conditions. In parallel, metabolomic analysis associated with genomic prediction and a molecular networking approach enabled us to evaluate the impact of bacterial lifestyle on chemically identified secondary metabolites, more precisely involved in microbial interactions and plant‐growth promotion. Notably, this work highlights the major effect of biofilm lifestyle on acyl‐homoserine lactone and phenazine production in P. chlororaphis strains.

Published: August 2020

AbstractKomatiites are presented as direct evidence for higher mantle temperatures during the Archean. In the North China Craton, komatiites with spinifex structure have been identified only at one locality, i.e. the Sujiagou area, western Shandong. They were considered as formed during the early Neoarchean mainly based on their association with supracrustal rocks considered to be that age. This study carried out SHRIMP U‐Pb zircon dating on metamorphosed trondhjemitic and monzogranitic dykes intruding the Sujiagou komatiites, and they have magmatic zircon ages of 2592 ± 12 Ma and 2586 ± 13 Ma respectively. This provides direct evidence that the komatiites formed during the early Neoarchean.
Subduction and Collision of the Jinsha River Paleo‐Tethys: Constraints from Zircon U‐Pb Dating and Geochemistry of the Ludian Batholith in the Jiangda–Deqen–Weixi Continental Margin Arc
Authors: HE Juan , WANG Baodi , WANG Qiyu 
Published: August 2020

AbstractThe Jiangda–Deqen–Weixi continental margin arc (DWCA) developed along the base of the Changdu–Simao Block and was formed as a result of the subduction of the Jinsha River Ocean Slab and the subsequent collision. The Ludian batholith is located in the southern part of the DWCA and is the largest batholith in northwest Yunnan. Granite samples from the Ludian batholith yield an early Middle Permian age of 271.0 ± 2.8 Ma. The geochemical data of the early Middle Permian granitoids show high Si2O, low P2O5 and MgO contents that belong to calc‐alkaline series and peraluminous I‐type rocks. Their ∊Hf(t) values range from –5.01 to +0.58, indicating that they were formed by hybrid magmas related to the subduction of the Jinsha River Tethys Ocean. The monzonite and monzogranite samples yield Late Permian ages of 250.6 ± 1.8 Ma and 252.1 ± 1.3 Ma, respectively. The Late Permian granitoids are high‐K calc alkaline and shoshonite series metaluminous I‐type rocks. Their ∊Hf(t) values range from –4.12 to –1.68 and from –7.88 to –6.64, respectively. The mixing of crustal and mantle melts formed the parental magma of the Late Permian granitoids. This study, combined with previous work, demonstrates the process from subduction to collision of the Jinsha River Paleo‐Tethys Ocean.

Published: August 2020

AbstractA consensus on Holocene climate variability at the modern northern fringe of the East Asian summer monsoon (EASM) region remains elusive. Here, we present a pollen‐based reconstruction of vegetation history and associated climate variations of a sediment core from Huangqihai Lake, central Inner Mongolia. During 10.7 to 8.8 cal kaBP, typical steppe with small patches of forest dominated the lake area, suggesting a moderately wet climate, followed by ameliorating climatic conditions until 8.0 cal kaBP as deduced by the expansion of forest. Typical steppe recovered the lake area between 8.0 and 7.2 cal kaBP, reflecting a deterioration of climatic conditions; in combination with other proxy records in the study region, we noticed that severe aridity was prevailed in the lake area between 8.0 and 7.6 cal kaBP. During 7.2 to 3.2 cal kaBP, abundant tree pollen indicated dominance of forest‐steppe around the lake, marking regionally wet conditions. A notable absence of broadleaved trees after 5.2 cal kaBP reveals a slight drying trend, and climate deterioration from 4.5 to 4.1 cal kaBP might be linked to the 4.2 ka event. After 3.2 cal kaBP, a transition to steppe was associated with dry conditions in the region. Based on our pollen record and prior paleoclimatic reconstructions in the Huangqihai Lake region, there was a generally‐accepted, stepwise shift to a wet climate during the early Holocene, an overall humid climate from 7.2 to 3.2 cal kaBP, and then severe drought for the rest of the Holocene. Moreover, regional comparisons among pollen records derived from lakes situated in the temperate steppe region suggested a roughly synchronous pattern of vegetation and climate changes during the Holocene and demonstrated an intensified EASM during the middle Holocene.

Published: August 2020

AbstractThis study deals with the relationship between sea‐level changes and paleoclimatic fluctuations based on the analysis of stratigraphy, grain sizes, palynology, and radiometric dating of the Yellow River delta since the Late Pleistocene. Evidence from the sedimentary record, grain sizes, and pollen provides a paleoenvironmental history of the Late Pleistocene from the boreholes of the delta. Based on a combination of grain‐size analysis with lithological studies, marine deposit units contain the intervals of 13.85–16.9, 18.5–19.69, 27.9–34.8, 36.4–37.2, 48.4–51.6, and 54.1–55.9 m, and transitional facies units contain the intervals of 10.25–13.85, 16.9–18.5, 19.69–27.9, 34.8–36.4, 37.2–48.4, 51.6–54.1, and 55.9–60 m, compared with fluvial (terrestrial facies) deposit units (3.36–10.25 m). Based on pollen analysis and pollen assemblages, there were three warm‐wet periods from 9.1–0.16 ka BP, 16.1–60 ka BP, and 90.1–94.6 ka BP From the top to the bottom of the borehole, the paleoclimate has an evident fluctuation: warm and moist (Holocene Optimum) —cool and dry (Younger Dryas Event)—mild semi cool—cool and dry—warm and moist. There were three warm‐wet periods from 9.1–0.16 ka BP, 16.1–60 ka BP, and 90.1–94.6 ka BP, corresponding to the Holocene Optimum stage, MIS 3, and MIS 5, respectively. The warm period allowed monsoonal evergreen and broadleaved deciduous forests that corresponded to Holocene hypsithermal climatic conditions and the Late Pleistocene climatic Optimum. Three warm‐wet periods occurred in marine deposit units from 9.1–0.16 ka BP, 60.1–16.1 ka BP, and 94.6–90.1 ka BP. These periods correspond to the Cangzhou transgression, Xianxian transgression, and Huanghua transgression, respectively. From 90.1–60.1 ka BP, 17.5–9.1 ka BP, and 0. 16 ka BP–1855 AD, three dry and cold phases are recognized. The phases indicate the fluvial (flood plain) sedimentary environment, corresponding to cooler and mild dry periods based on palynological results and grain‐size distribution.
Zircon U–Pb Geochronology and Petrogenesis of Early–Midlle Permian Arc–Related Volcanic Rocks in Central Jilin: Implications for the Tectonic Evolution of the Eastern Segment of Central Asian Orogenic Belt

Published: August 2020

AbstractThis paper presents age and geochemical data of a recently identified Late Paleozoic volcanic sequence in central Jilin Province, with aims to discuss the petrogenesis and to constrain the tectonic evolution of the Central Asian Orogenic Belt in this area. Firstly, the volcanic rocks have zircon U‐Pb ages of 290–270 Ma. Secondly, they are characterized by (a) ranging in composition from the low‐K tholeiite series to high‐K calc‐alkaline series; (b) enrichment in light rare earth elements and depletion of heavy rare earth elements, with negative Eu anomalies; and (c) negative Nb, Ta, and Ti anomalies. Finally, the volcanic rocks yield ∊Hf(t) values of +7.1 to +17. These data suggest that the central Jilin volcanic rocks were possibly derived from predominant partial melting of a depleted lithospheric mantle that might have been modified by subducted slab–derived fluids. Combined with previous studies, the Late Paleozoic–Early Mesozoic magmatism in Central Jilin can be divided into two stages: (a) a volcanic arc stage (290–270 Ma) represented by low‐K to high–K, tholeiite to calc–alkaline plutons and (b) a syn–collisional stage (260–240 Ma) represented by high‐K calc–alkaline I‐type granites. Furthermore, the timing and the tectonic setting of the above magmatic rocks show that the arc was probably produced by the northward subduction of the Paleo‐Asian Ocean and that the final closure of the Paleo‐Asian Ocean occurred prior to the Early Triassic.

Published: August 2020

AbstractAimOsteoarthritis (OA) is a chronic degenerative joint disease. Early studies have indicated that genetic and environmental factors contribute to the risk of OA. However, the etiology of OA remains unknown. Our study aimed to evaluate the association of DNMT3B gene with the risk of hip OA in Han Chinese individuals.MethodsA total of 2070 subjects were recruited into the study, including 658 patients with hip OA and 1412 healthy controls. Twelve tag single nucleotide polymorphisms (SNPs) were selected and genotyped in our samples. Genetic associations between DNMT3B gene and the risk of hip OA were examined at both the single marker and haplotype levels. Cis‐expression quantitative trait loci signals that achieve genome‐wide significance of targeted SNPs from multiple types of human tissues were extracted from the GTEx database.ResultsSignificant signals were identified for SNP rs2424905 in 4 genetic models. The T allele was significantly associated with an increased risk of hip OA (odds ratio = 1.53; 95% CI = 1.28‐1.83). The T allele was also significantly associated with higher Kellgren–Lawrence grade in the patients with hip OA (χ2 = 32.70, P = 1.37 × 10−6). Moreover, SNP rs2424905 was significantly associated with the gene expression level of multiple genes, including DNMT3B, C20orf203, COMMD7, EFCAB8, MAPRE1, and RP5‐1085F17.3, from several types of human tissues.ConclusionOur results indicated that rs2424905 of DNMT3B gene contributed to the risk of hip OA and its clinical severity in a Han Chinese population. These findings suggested that rs2424905 of DNMT3B could be a promising genetic marker to assess susceptibility to hip OA in Han Chinese populations.
