Chinese consumers’ willingness-to-pay for nutrition claims on processed meat products, using functional sausages as a food medium
Authors: Hong Xinyi , Li Chenguang , Bai Junfei , Gao Zhifeng , Wang Liming 
Published: March 2021

PurposeFollowing the standard practice of using nutrition claims to denote food functionality, this study empirically explores Chinese consumers’ willingness-to-pay for functional processed meat products by using three nutrition claims (namely “increased calcium,” “containing omega-3”, and “reduced salt”) made on pork sausages. It also aims to outline the typical characteristics of Chinese consumer segments based on preferences.Design/methodology/approachA choice-based choice experiment is utilized to investigate Chinese consumers’ valuation on attributes of interest regarding functional sausage products. First-hand data was collected in the two cities of Xi'an and Beijing.FindingsThere are market potentials for domestic and/or imported functional processed meat products among Chinese consumers. Nutrition claims made on pork sausages are appealing to Chinese consumers, and therefore, monetarily rewarded by them. Being imported from a more developed country of origin could both positively and negatively impact consumers’ WTP for nutrition claims made on pork sausages. Furthermore, specific functional modification strategies should be taken into account when addressing different segments of the Chinese market. In addition, regional impacts between Xi'an and Beijing are implied in terms of consumers’ valuation for functional pork sausages.Research limitations/implicationsLimitations in the current study are mainly two folds. First, the WTP estimation magnitudes are subject to a hypothetical bias by using a stated preference approach. Second, this study only focuses on pork sausages to explore consumers’ perceptions and selects three nutrition claims among many other relevant options.Practical implicationsImplications are provided for meat marketers and for Chinese official food policymakers, such that promoting meat products with a nutrition claim is an attractive marketing strategy for foreign food manufacturers in China, and more reformulated meat products with better nutritional compositions should be allowed in the Chinese market.Originality/valueTo the best of the author’s knowledge, this research is the first to fill in the literature blank on investigating the consumers’ valuation for functional meat in the emerging market of China. Because when taking Chinese consumers as a target market and evaluating their perceptions of food quality-related labeling and certifications, the existing literature is mainly limited to topics of product safety, organic/green products, and geographical origins. However, nutrition claims, as marketable credence attributes that associate closely to the main characteristics of the functional food products, have been explored to a much lesser extent among Chinese consumers.
Does income shock affect informal employment? Evidence from Russia
Authors: Kim Olivia Hye 
Published: March 2021

PurposeThe purpose of this study is to examine whether participating informality is attributed to income shocks such as wage arrears, unexpected wage cuts or compulsory unpaid leaves. The current research uses Russia longitudinal Monitoring Survey 2002–2015.Design/methodology/approachUsing formal jobs as the base category, the authors conducted pooled multinomial logit regressions allowing for the two additional employment statuses: workers without contracts and unincorporated business workers.FindingsThe overall results mainly suggest that no effects occur. In other words, unexpected negative income shocks are not the main driving force of informality. Although the majority of previous studies are based on survey questions on unexpected income shock which has sample selection bias, to obtain robustness, the current study used Russian minimum wage reforms as income shocks. This research shows that Russian minimum wage reform does not affect the decision of informality in the labor market.Research limitations/implicationsGiven the data limitations, the authors only observed and examined the supply-side of the labor market. Tax-evading motives would be the main reason for informality; to ensure this conjecture, however, demand and supply sides need to be simultaneously examined which is beyond the scope of this study.Originality/valueIn contrast to a large number of studies on cross-sectional differences in determinants of informal job holding, emphasis on the effects of income shocks on informal employment across business cycles has been minimal. The current study focuses on the business cycles because trends of informal employment can be interpreted differently regardless of whether in an economic boom or recession. Russia, as a unique natural experiment, provides us to examine informal job holdings over the business cycle.
A cross-level examination of team-directed empowering leadership and subordinates' innovative performance: an AMO theory perspective
Authors: Cui Yang , Yu Guilan 
Published: March 2021

PurposeIn the field of innovation, individual innovative performance also has an important impact on team and organizational innovative performance, thus it is necessary to identify factors that increase individual innovative performance. One key to unlock individual innovative performance is empowering leadership. Drawing on the Ability-Motivation-Opportunity (AMO) theoretical framework, this study investigates the cross-level influence of team-directed empowering leadership on subordinates' innovative performance and verifies the mediating role of creative self-efficacy (A), intrinsic motivation (M), team knowledge sharing (O) and the moderating effect of feedback seeking climate.Design/methodology/approachWith a sample of 102 teams and 722 employees, this study uses Mplus7.4 software to carry out cross-level model analysis based on MSEM multilevel mediation test methodology.FindingsThe results from cross-level analysis indicate that: (1) Team-directed empowering leadership has a significant positive impact on subordinates' innovative performance. (2) Team-directed empowering leadership enhances subordinates' innovative performance through the improvement of creative self-efficacy, intrinsic motivation and team knowledge sharing. (3) Based on the feedback perspective, feedback seeking climate moderates the relationship between team-directed empowering leadership and creative self-efficacy, intrinsic motivation and team knowledge sharing.Originality/valueThis study introduced the AMO theory into the research on cross-level mediating mechanism between team-directed empowering leadership and subordinates' innovative performance, which broadens the theoretical research perspective. Considering the difference between empowering leadership and laissez-faire leadership and the guiding role of feedback, this study selects feedback seeking climate as a moderator in view of feedback, which riches the contingency factors on the cross-level effect of team-directed empowering leadership.

Authors: Pant Himani , Singh S.B. 
Published: March 2021

PurposeThe system encountering dormant failure subject to sequential inspections is modeled and the emphasis is made on determining the availability and long-run average cost rate for the model. The derived results are then utilized to obtain the optimal inspection period minimizing the cost.Design/methodology/approachExplicitly, a system with a functional and a failed state is taken into account. Inspections are performed to reveal the dormant failures and are assumed to be carried out at time T, T + aT, T + aT+a2 T, … where 0 < a = 1 in each cycle. Perfect repairs taking random times are performed if the system is found in a failed state during any inspection.FindingsSome theorems on the point availability, limiting availability and long-run average cost rate are obtained in the study. An illustration is shown to explain the results obtained in the proposed work. The effect of inspection time on the availability and cost rate is also analyzed graphically.Originality/valueThe availability and cost rate for a system with dormant failure under a sequential inspection policy are figured out unlike previous research.

Published: March 2021

PurposeThe aim of this study is to explore the drivers of the evolution of a subsidiary’s strategic role from an ordinary subsidiary into a springboard subsidiary in multinational corporations, paying special attention to the role of subsidiary management in this transformation.Design/methodology/approachThe authors apply a case study methodology to analyse the transformation of three Spanish subsidiaries of European multinational companies into springboard subsidiaries to pursue opportunities in the Latin American region.FindingsThe results present evidence that the development of a springboard subsidiary’s role is influenced by a set of preliminary factors that include: (1) the coincidence of a favourable economic change in the target region of expansion and unfavourable market conditions in the springboard subsidiary’s home market; (2) location-specific advantages of a subsidiary that allow it to develop unique capabilities, such as the ability to reduce the psychic distance between the headquarters and target region, to balance intra-regional conflicts within the target region, and to effectively transfer knowledge from the headquarters to the target region; and (3) micro-political headquarters-subsidiary negotiation processes as a result of the subsidiary’s strong initiative, peculiarities of the structure of a multinational company, and a strong dependency of the headquarters on the subsidiary’s unique capabilities.Originality/valueThe study contributes to the International Business literature by providing an in-depth analysis of the evolution of springboard subsidiaries and explaining how ordinary subsidiaries located in saturated markets can trigger organisational change and achieve the extension of their strategic role.
The New Trading ‘Relationship’ between Great Britain and Northern Ireland: Why, What and How
Authors: Hayward Katy 
Published: March 2021

AbstractThe protocol on Ireland/Northern Ireland proved to be the trickiest element of the UK‐EU Withdrawal Agreement to negotiate. The version that was finally agreed to by both sides sees the EU's customs code and regulatory rules applying in Northern Ireland. In avoiding a hard border for the movement of goods on the island of Ireland, there are new frictions on the movement of goods within the United Kingdom (across the Irish Sea). Implementing the protocol is a complex practical as well as political challenge. What it means in practice is largely dependent on the nature of the UK‐EU relationship.

miRNAs targeting CYP6ER1 and CarE1 are involved in nitenpyram resistance in Nilaparvata lugens
Authors: Mao Kaikai , Jin Ruoheng , Ren Zhijie , Zhang Junjie , Li Zhao , He Shun , Ma Kangsheng , Wan Hu , Li Jianhong 
Published: March 2021

AbstractThe evolution of nitenpyram resistance has been confirmed to be related to overexpression of two key metabolic enzyme genes, CYP6ER1 and CarE1, in Nilaparvata lugens, a highly destructive rice pest that causes substantial economic losses and has developed insecticide resistance. As microRNAs (miRNAs) are important post‐transcriptional regulators of gene expression, whether they are involved in nitenpyram resistance is poorly understood in N. lugens. In this study, knockdown of key genes in the miRNA biogenesis pathway (Dicer1, Drosha, and Argonaute1) changed CYP6ER1 and CarE1 abundance, which confirmed the importance of miRNAs in nitenpyram resistance. Furthermore, global screening of miRNAs associated with nitenpyram resistance in N. lugens was performed, and a total of 42 known and 178 novel miRNAs were identified; of these, 57 were differentially expressed between the susceptible and resistant strains, and two (novel_85 and novel_191) were predicted to target CYP6ER1 and CarE1, respectively. Luciferase reporter assays demonstrated that novel_85 and novel_191 bind to the CYP6ER1 and CarE1 coding regions, respectively, and downregulate their expression. Moreover, modulating novel_85 and novel_191 expression by injection of miRNA inhibitors and mimics significantly altered N. lugens nitenpyram susceptibility. This is the first study to systematically screen and identify miRNAs associated with N. lugens nitenpyram resistance, and provides important information that can be used to develop new miRNA‐based targets in insecticide resistance management.
Geochronology, Fluid Inclusions and Isotopic Characteristics of the Dongjun Pb‐Zn‐Ag Deposit, Inner Mongolia, NE China

Published: March 2021

AbstractThe Dongjun Pb‐Zn‐Ag deposit in the northern part of the Great Xing'an Range (NE China) consists of quartz‐sulfide vein‐type and breccia‐type mineralization, related to granite porphyry. Hydrothermal alteration is well‐developed and includes potassic‐silicic‐sericitic alteration, phyllic alteration and propylitic alteration. Three stages of mineralization are recognized on the basis of field evidence and petrographic observation, demarcated by assemblages of quartz‐pyrite‐arsenopyrite (early stage), quartz‐polymetallic sulfide (intermediate stage) and quartz‐carbonate‐pyrite (late stage). Zircon LA‐ICP‐MS U‐Pb dating indicates that the granite porphyry was emplaced at 146.7 ± 1.2 Ma (Late Jurassic). Microthermometry and laser Raman spectroscopy shows that ore minerals were deposited in conditions of intermediate temperatures (175–359°C), low salinity (0.5–9.3 wt% NaCl eqv.) and low density (0.60–0.91 g/cm3). Ore‐forming fluids were derived largely from magmatic hydrothermal processes, with late‐stage addition of meteoric water, belonging to a H2O‐NaCl‐CO2 ± CH4 system. The δ34SV‐CDT values range from 0.75‰ to 4.70‰. The 206Pb/204Pb, 207Pb/204Pb, and 208Pb/204Pb values of the ore minerals are in the ranges of 18.240–18.371, 15.542–15.570, and 38.100–38.178, respectively. Data for the S and Pb isotopic systems indicate that the ore‐forming metals and sulfur were derived from Mesozoic magma. Based on the geological characteristics and geochemical signatures documented in this study, we conclude that the Dongjun deposit is a mesothermal magmatic hydrothermal vein‐type Pb‐Zn‐Ag deposit controlled by fractures and related to granite porphyry, in response to Late Jurassic tectonic–magmatic–hydrothermal activity. We further conclude that fluid immiscibility, fluid mixing and fluid‐rock interactions were the dominant mechanisms for deposition of the ore‐forming materials.
Characteristics of Hydrogen‐rich Coals in Southern China: Implications from Organic Geochemistry and Carbon Isotopic Compositions
Authors: LIN Yuhan , WANG Shaoqing , YANG Zongda , ZHAO Yungang , YANG Yi 
Published: March 2021

AbstractThe organic geochemical characteristics of hydrogen‐rich coal in southern China were investigated synthetically through organic geochemistry and carbon isotope analyses. The results showed that the hydrogen contents of the test samples were more than 5.0% and the H/C atomic ratios were between 0.76–1.06. Samples were found to be composed mostly of Type II‐III kerogen, consistent with good hydrocarbon‐generation potential. The Ro (0.54–1.10%) and Tmax (430–453°C) values imply that the hydrogen‐rich coals were in low maturity to mature stages. Stable carbon isotopic ratios (δ13Corg) of the samples used varied from –24.5‰ to –23.4‰, the barkinite content ranging from 13.9% to 83.3%, indicating a predominantly terrestrial origin with marine influence during coal formation. Some organic geochemical parameters showed corresponding changes as the hydrogen content increased from 5.0% to 7.0%, however, the source inputs changed significantly when hydrogen content was greater than 6.0%. Terrestrial higher plants gradually become predominant within the coal‐forming materials, whereas this dominant position is not apparent at lower hydrogen contents, which is attributable to the strong seawater effect during the hydrogen‐rich coal formation process.

Published: March 2021

AbstractThe hydrogeochemical characteristics of geothermal fluids can reveal the genesis of geothermal systems and act as important references for developing and using geothermal resources. This study presents hydrogeochemical processes and thermal cycle mechanisms of typical geothermal fields in Western Sichuan. Based on the geological conditions in Western Sichuan, 29 hot springs in three geothermal fields in the Batang and Litang areas were selected for hydrochemical and isotopic (δD and δ18O) analyses. Furthermore, the temperature of the thermal reservoir was calculated and the upflow cooling process of the hot springs was analyzed. Most of the subterranean hot waters in Batang and Litang are of the HCO3‐Na hydrochemical type. The ion variation in Batang is primarily affected by water‐rock interactions. There is a strong positive correlation between Na+, B−, and Cl− in Litang, suggesting that they have the same material source. The Na+ and metaboric acid content is relatively high, which indicates that the groundwater runoff in both areas is relatively long‐lasting, with reduced flow velocity; moreover, the metasilicic acid content is relatively high, which supports this conclusion. Both hydrogen and oxygen isotopes plot near the atmospheric precipitation line, indicating that groundwater recharge is functionally obtained from precipitation. The calculated thermal storage temperatures in Batang and Litang were 88–199°C and 96–154°C, respectively. The proportion of cold water mixing in Batang was 64%–67%, while that in Litang was 60%–68%. According to the calculated results, the initial thermal cycle depth of the Batang area (4540–4780 m) was greater than that of the Litang area (3150–3960 m). The enthalpy of the deep parental geothermal fluid in Batang was 1550 J/g with a Cl− concentration of 37 mg/L, while that in Litang was 2100 J/g with a Cl− concentration of 48 mg/L.
The site of Al‐Qurainiyah: Topography and phases of an early Islamic coastal settlement on Failaka Island
Authors: Di Miceli Andrea 
Published: March 2021

AbstractThis paper presents the latest finds from the early Islamic site of Al‐Qurainiyah on Failaka Island, Kuwait. Trenches opened to the west of the main late Islamic village led to the identification of residential buildings and a workshop located along the shoreline, while the pottery assemblage suggests a permanent occupation from at least the seventh century CE to the early ninth century CE. The last two years of excavations allowed us to uncover archaeological contexts that seem to indicate a previous occupation, dating to the late Hellenistic period (second century BC). The long‐term occupation, strategic position of the settlement facing a wide and well‐sheltered lagoon, as well as the installation of a stable settlement in the same period of Al‐Qusur—the main early Islamic site of the island—seem to suggest the interpretation of Al‐Qurainiyah as a landing place used both in the early Islamic period and beforehand.
