What Drives Chinese Firms' Export Sophistication? A Perspective from the Rise of Minimum Wages
Authors: Li Xiaoping , Peng Shuzhou , Huang Wei‐Chiao , Zhou Qian 
Published: March 2022

AbstractThis paper re‐examines the driving factors behind the upgrading of China's export sophistication. Based on county‐level minimum wages and firm‐level export data for 2000–2013, this paper finds that the labor cost shocks caused by rising minimum wages have a significant positive impact on Chinese firms' export sophistication. Channel tests show that the positive effect of rising minimum wages on firms' export sophistication derives from the exit of less sophisticated products and the reallocation of the relative share of surviving products, rather than introducing new highly sophisticated products. Heterogeneity analysis reveals that rising minimum wages have a greater impact on export sophistication for low‐wage firms, domestic firms, and labor‐intensive firms. This paper has implications for developing countries regarding the transition from a low‐cost labor trade model to a sophistication‐driven trade model.
Decomposition Analysis of Poverty Reduction in Rural China: 2007–2018
Authors: Luo Chuliang 
Published: March 2022

AbstractUsing the last three waves of the rural household surveys conducted by the Chinese Household Income Project in 2007, 2013, and 2018, this paper focuses on changes in poverty in rural China. The paper decomposes poverty change into the growth effect and the inequality effect, and also decomposes the contributions of income components, concentrating particularly on income from public transfers. Economic growth had a very significant poverty reduction effect for both absolute and relative poverty, but the inequality effect mostly offset it; in total, absolute poverty reduced significantly, and relative poverty increased from 2007 to 2018. Local wage income became the main contributor to both absolute and relative poverty reduction, replacing household agricultural operational income, and the contribution of wage income from migration declined. Public transfers effectively reduced absolute poverty but not relative poverty.

Published: March 2022

AbstractWe studied the role of sensorimotor and working memory systems in supporting development of perceptual rhythm processing with 119 participants aged 7–12 years. Children were assessed for their abilities in sensorimotor synchronization (SMS; beat tapping), auditory working memory (AWM; digit span), and rhythm discrimination (RD; same/different judgment on a pair of musical rhythm sequences). Multiple regression analysis revealed that children's RD performance was independently predicted by higher beat tapping consistency and greater digit span score, with all other demographic variables (age, sex, socioeconomic status, music training) controlled. The association between RD and SMS was more robust in the slower tempos (60 and 100 beats‐per‐minute (BPM)) than faster ones (120 and 180 BPM). Critically, the relation of SMS to RD was moderated by age in that RD performance was predicted by beat tapping consistency in younger children (age: 7–9 years), but not in older children (age: 10–12 years). AWM was the only predictor of RD in older children. Together, the current findings demonstrate that the sensorimotor and working memory systems jointly support RD processing during middle‐to‐late childhood and that the degree of association between the two systems and perceptual rhythm processing is shifted before entering into early adolescence.

AbstractAimsTo determine the association between registered mental illness and type 2 diabetes mellitus treatment targets, while taking into account the effects of health expenditure and social determinants of health.MethodsThis observational cross‐sectional study was based on routine primary care data, linked to socio‐economic and medical claims data. The main outcomes, analysed by multivariate logistic regression, were achieving primary care guideline treatment targets for HbA1c, systolic blood pressure (SBP) and LDL‐cholesterol in 2017. We examined the association with diagnosed mental illness registered by the general practitioner (GP) or treated via specialist’ mental healthcare between 2016 and 2018, adjusting for, medication use, body mass index, co‐morbidity, smoking, and additionally examining effect‐modification of healthcare expenditures, migration status, income and demographics.ResultsOverall (N = 2862), 64.0% of participants achieved their treatment targets for HbA1c, 65.1% for SBP and 53.0% for LDL‐cholesterol. Adjusted for migrant background, income and care expenditures, individuals <65 years of age with mental illness achieved their HbA1ctreatment target more often than those without (OR (95% CI)): treatment by GP: 1.46 (1.01, 2.11), specialist care: 1.61 (1.11, 2.34), as did men with mental illness for SBP: GP OR 1.61 (1.09, 2.40), specialist care OR 1.59 (1.09, 2.45). LDL‐cholesterol target was not associated with mental illness. A migrant background or low income lowered the likelihood of reaching HbA1ctargets.ConclusionsPeople with registered mental illness appear comparable or better able to achieve diabetes treatment targets than those without. Achieving HbA1ctargets is influenced by social disadvantage.
Economic and health impacts of Helicobacter pylori eradication strategy for the treatment of peptic ulcer disease: A cost‐effectiveness analysis
Authors: Kowada Akiko , Asaka Masahiro 
Published: March 2022

AbstractBackgroundMost peptic ulcer cases are associated with Helicobacter pylori (H. pylori) infection or the use of nonsteroidal anti‐inflammatory drugs (NSAIDs). H. pylori eradication therapy is recommended for the treatment of H. pylori‐positive peptic ulcers. We aimed to assess and validate the cumulative economic and health effects of H. pylori eradication strategy for the treatment of peptic ulcers compared with PPI therapy strategy.Materials and MethodsWe developed a cohort state‐transition model for H. pylori eradication strategy and PPI therapy strategy over a lifetime horizon from a healthcare payer perspective. We targeted two hypothetical cohorts of H. pylori‐positive patients with gastric and duodenal ulcers aged 20, 30, 40, 50, 60, 70, and 80. The main outcomes were costs, quality‐adjusted life‐years (QALYs), life expectancy life‐years (LYs), incremental cost‐effectiveness ratios, ulcer recurrence cases, and ulcer‐associated deaths. One‐way and probabilistic sensitivity analyses were conducted to assess the impact of uncertainty.ResultsIn the base‐case analysis, H. pylori eradication strategy was less costly with greater benefits than PPI therapy strategy in all age groups. Cost‐effectiveness was not sensitive to any variables in all age groups. Sensitivity analyses showed strong robustness of the results. From 2000 to 2020, H. pylori eradication strategy saved US$14.07 billion over a lifetime, increased 8.65 million QALYs and 1.23 million LYs over a lifetime, and prevented 551,298 ulcer recurrence cases and 59,465 ulcer‐associated deaths, compared with PPI therapy strategy.ConclusionsH. pylori eradication strategy not only has contributed significantly to preventing ulcer recurrence and reducing ulcer‐associated deaths but also has resulted in great cost savings. All over the world, H. pylori eradication strategy is likely to have yielded a comparable magnitude of economic and health benefits, depending on the epidemiology of H. pylori‐related peptic ulcers and the healthcare environment in each country.
Stressing the need for validated measures of cortisol in HIV research: A scoping review

Published: March 2022

AbstractObjectivesPeople living with HIV experience numerous endocrine abnormalities and psychosocial stressors. However, interactions between HIV, cortisol levels, and health outcomes have not been well described among people living with HIV on effective therapy. Furthermore, methods for measuring cortisol are disparate across studies. We describe the literature reporting cortisol levels in people living with HIV, describe methods to measure cortisol, and explore how this relates to health outcomes.MethodsWe searched the PubMed database for articles published in the past 20 years regarding HIV and cortisol with ≥50% of participants on antiretroviral therapies. Articles included observational, case‐control, cross‐sectional, and randomized controlled trials analyzing cortisol by any method. Studies were excluded if abnormal cortisol was due to medications or other infections. Variables were extracted from selected studies and their quality was assessed using the Newcastle–Ottawa Scale.ResultsIn total, 19 articles were selected and included, covering the prevalence of abnormal cortisol (n = 4), exercise (n = 4), metabolic syndrome and/or cardiovascular disease (n = 2), mental health and cognition (n = 9), and sex/gender (n = 6). Cortisol was measured in serum (n = 7), saliva (n = 8), urine (n = 2), and hair (n = 3) specimens. Comparisons between people with and without HIV were inconsistent, with some evidence that people with HIV have increased rates of hypocortisolism. Depression and cognitive decline may be associated with cortisol excess, whereas anxiety and metabolic disease may be related to low cortisol; more data are needed to confirm these relationships.ConclusionsData on cortisol levels in the era of antiretroviral therapy remain sparse. Future studies should include controls without HIV, appropriately timed sample collection, and consideration of sex/gender and psychosocial factors.

SummaryComposite flours were prepared from blends of yellow maize (Zea mays), sesame seed (Sesamum indicum) and oyster mushroom (Pleurotus ostreatus) powder in the ratio of 80:20:0; 75:20:5; 70:20:10; 65:20:15 and 60:20:20, respectively to produce the cereal‐based breakfast product coded as YSB, SMB, TMB, PMB and OMB with YSB as the control. The breakfast cereals were produced by hydration and toasting of yellow maize and sesame to 160°C for 25 min and blended together with oven‐dried and packaged oyster mushroom. The developed products were analysed for proximate, vitamins, minerals and sensory properties. The proximate composition (%) of different blends ranged as moisture (4.07–7.08), ash (3.09–2.28), crude fat (16.04–12.83), crude fibre (4.30–8.22), protein (16.14–22.54), carbohydrate (56.34–47.04) and energy (434.34–393.83 Kcal). Vitamin A (7.99–5.98 mg/100 g), vitamin B1(0.08–0.42 mg/100 g), vitamin B2(0.06–0.15 mg/100 g), vitamin B3(1.91–4.52 mg/100 g) and vitamin C (3.55–3.32 mg/100 g) were u while minerals (mg/100 g) were calcium (75.31–58.02), potassium (0.65–4.01), magnesium (12.25–12.62), iron (1.21–4.15) and zinc (0.40–1.32). Sensory scores revealed that the cereal‐based breakfast product were acceptable to the panellist with oyster mushroom supplementation up to 10%.

ABSTRACTSaffron production from Crocus sativus flowers produces large amounts of by‐products that may represent an excellent source of polyphenols. The aim of this work was to evaluate infusions originating from different brewing processes and from different saffron flower portions, in terms of both functional and sensory traits. For this aim, total polyphenols and total flavonoids, in vitro antioxidant assays and an untargeted phenolic profiling were applied. In general, tepals showed higher polyphenol and flavonoid content than stamen infusions, and their bioactive content depended more on brewing temperature than brewing time. These findings were consistent with both antioxidant capacity and phenolic profiling. Multivariate statistics highlighted polyphenols discriminating ‘boiled’ vs. ‘cold’ infusions, being mainly flavonoids, phenolic acids and the alkylphenol 5‐pentadecylresorcinol (showing a strong down‐accumulation at the higher brewing temperatures). Positive correlations could be highlighted between anthocyanins, flavones, flavonols and lignans, and the in vitro antioxidant assays. In general, cold brewing was successful in extracting phenolic compounds and provided better sensory properties, thus indicating that this may represent a valuable strategy to develop saffron‐based functional beverages with better consumers' acceptability.

Published: March 2022

SummaryChestnut and chickpea flours have interesting nutritional characteristics and can be incorporated into layer cake formulations. This study aims to evaluate the effect of incorporating mixtures of these flours with wheat flour in the elaboration of layer cakes. With this aim, layer cakes were elaborated with the three different flours. Mixes of 50% of these flours and a mixture of the three flours in the same proportion were analysed. Batter density, microstructure and viscosity, as well as the specific volume, texture and acceptability of layer cakes were evaluated. Chickpea flour reduced the batter density and increased viscosity compared to wheat flour, while chestnut flour reduced viscosity and did not clearly affect density. Although both flours produced layer cakes with lower specific volume, as well as less cohesive and springiness, the effect on specific volume was clearer in chestnut flour. With 50% of chickpea flour, it was possible to obtain layer cakes with the same specific volume and hardness as those made with wheat flour. Layer cake acceptability decreased with the reduction in wheat flour, regardless of the type of flour incorporated. No improved acceptability has been found when combining chickpea and chestnut flours.

SummaryTofu was made by substituting kenaf seed (K) with soybean (S) at 100 (positive control), 50%, 40%, 30%, 20%, 10% and 0% (negative control). The results indicated that kenaf seed substitution at all ratios significantly increased the soluble solids and protein content of the milky extracts. The yield, moisture and protein content of the tofu were significantly increased with the increase in kenaf seed substitution, while the lipid content was significantly decreased. The tofu made with kenaf seed substitution of 50%, 40% and 30% had the same protein content (43.76–45.36 g/100 g) with the positive control (45.36 g/100 g), but a significantly higher lipid content (32.00–35.75 g/100 g) than that of the positive control (27.50 g/100 g). The microstructure of the tofu revealed that only the positive control had a honey‐comb structure, whilst the tofu made from kenaf seed‐soybean blends had a pseudo‐honey like structure. Up to 30% of soybean can be added into the kenaf‐based tofu, without any negative effect on the textural and colour properties and, protein content, but significantly improved the essential amino acids content of the kenaf‐based tofu. Therefore, the blend of 70K:30S ratio using 0.5 g% glucono delta‐lactone as a coagulant is recommended to produce kenaf seed‐soybean tofu.

Published: March 2022

AbstractThe objective of this study was to determine the suitability of different soft‐endosperm commercial maize hybrids to obtain polenta of good technological quality. Ten commercial soft‐endosperm hybrids and two open‐pollinated varieties (quality controls) of maize were used. Grain physical characteristics were determined, and polentas from each genotype were obtained. The chemical composition of semolina was determined, and polenta was evaluated in terms of viscoelasticity, cooking characteristics and colour. The semolina yield was between 50.96 to 69.36%. The control genotypes showed the lowest values for peak viscosity, with 3670.5 and 3966.25 cP. Hybrid Next22.6 showed the highest consistency value, while C6006, Col17, Ds507 and Srm566 presented the lowest value of all samples tested. Hybrid N7822 first, followed by Ds507 and Srm553, proved to be suitable for the food industry. The good characteristics of this dish were associated with high pasting temperature and semolina yield, and low consistency and viscosity values.

Published: March 2022

SummaryIn this study, grape pomace (mixture of grape seeds and skins) powder (GPP), obtained from grape processing, was used at different concentrations [10.0 (GPP10), 20.0 (GPP10) and 30.0 (GPP10) g/100 g] in white chocolate formulation for the partial replacement of sucrose. The results indicated that GPP addition at a higher concentration (>10.0 g/100 g) significantly affected the particle size, moisture content, texture and flow behaviour of white chocolate samples (P < 0.05). However, using GPP at a concentration of 10.0 g/100 g had advantages for physicochemical and flow properties. As expected, under simulated in vitro digestion conditions, the bioaccessibility of total phenolic compounds in saliva, gastric juice and intestinal juice for GPP10 samples was significantly higher than the control (P < 0.05). In conclusion, results of the study showed that it was possible to partially replace the sucrose with GPP at a concentration of 10.0 g/100 g in white chocolate formulations.

AbstractA new series of rare‐earth‐cerate high‐entropy ceramics with compositions of (La0.2Nd0.2Sm0.2Gd0.2Dy0.2)2Ce2O7 (HEC1), (La0.2Nd0.2Sm0.2Gd0.2Yb0.2)2Ce2O7 (HEC2), (La0.2Nd0.2Sm0.2Yb0.2Dy0.2)2Ce2O7 (HEC3), (La0.2Nd0.2Yb0.2Gd0.2Dy0.2)2Ce2O7 (HEC4), (La0.2Yb0.2Sm0.2Gd0.2Dy0.2)2Ce2O7 (HEC5) as well as a single component of Nd2Ce2O7 are fabricated via sintering the corresponding sol–gel‐derived powders at 1600°C for 10 h. HEC1–5 samples exhibit a single‐cerate phase with fluorite structure and high configurational entropy. Compared with Nd2Ce2O7, HEC1–5 samples have a lower grain growth rate owing to the sluggish diffusion effect. The chemical compositional uniformity of HEC1–5 as well as Nd2Ce2O7 does not apparently change after annealing at 1500°C for different time intervals (1, 6, 12, and 18 h). Compared with 8YSZ, HEC1–5 samples display the decreased thermal conductivity and increased thermal expansion coefficient. The lattice size disorder parameter of HEC1–5 is negatively related to the thermal conductivity in 26–450°C. Furthermore, HEC1–5 and Nd2Ce2O7 exhibit lower oxygen‐ion conductivity, meaning an increased resistance to oxygen diffusion.

AbstractAimMajor knowledge gaps exist regarding the evolution of arid zone organisms. For freshwater species with high dispersal potential, little is known if historical aridification influenced connectivity across drainage divides and impacted on their divergence and diversification. We tested the hypothesis that the historical aridification of Australia promoted the isolation and influenced the demographic histories and evolutionary divergence of a migratory group of freshwater obligates.LocationCentral and eastern Australia; Murray–Darling Basin (MDB), Lake Eyre Basin (LEB), Fitzroy Basin (FIT).TaxonThree lineages of golden perch (Macquaria ambigua), a widespread fishery resource from inland Australia.MethodsWe obtained genome‐wide data for golden perch sampled throughout their range. Phylogenetic relationships were reconstructed using maximum likelihood. Species distribution modelling was used to predict contemporary and past distributions for the three lineages and to develop hypotheses regarding their biogeographic and demographic histories. Hypotheses were independently tested using coalescent simulations in fastsimcoal and DIYABC with the genomic dataset.ResultsWe found evidence for three reciprocally monophyletic lineages that have experienced little to nil genetic connectivity since divergence. Coalescent models suggest that the coastal (FIT) and inland (MDB and LEB) lineages diverged ~103 thousand years ago (ka), followed by the split of MDB and LEB lineages ~58 ka. These timings agree with reductions of large freshwater environments in Australia during the late Pleistocene. Species distribution models show an extreme decrease in habitat during the Last Glacial Maximum ~21 ka, consistent with inferred demographic contractions in coalescent tests.Main conclusionsWe reveal that aridification of Australia during the late Pleistocene has driven and reinforced the divergence of a migratory freshwater obligate. Our findings are important for informing the conservation management of aquatic organisms under climate change. This work further demonstrates the value of using species distribution modelling to formulate diversification hypotheses and to improve interpretation of coalescent analyses.
