Formal Employment, Informal Employment and Income Differentials in Urban China

Oaxaca’s study (1973), along with the China Health and Nutrition Survey (CHNS) questionnaire (2004 and 2006 pooling data), is used as the basis for this study in estimating the formal-informal employment hourly income differential, as well as the formal and informal male-female employment hourly income differential in urban China. The results indicate that differences in the characteristics between formal and informal employment account for a much higher percentage of the hourly income differential than do discrimination. In addition, ignoring the sample selection bias, one finds the formal male-female, the informal male-female hourly income differential and the degree of discrimination against informal women’s employment will be overestimated; conversely, the degree of discrimination against formal women’s employment will be underestimated.formal employment; informal employment; income differentials; Chinese labor market

Energy prices and China’s international competitiveness

This paper uses the CCF approach to analyze and determine whether there is a causal relationship between the world energy price index and China’s international competitiveness. The data on the volatility of energy prices can provide information in addition to that available in the price data alone. Our analysis suggests that the volatility of energy prices has significant implications concerning information linkages between the energy market and China’s international competitiveness.energy prices; international competitiveness; CCF approach; Chinese economy

Do Chinese employers discriminate against females when hiring employees ?

In order to examine whether Chinese employers discriminated against females during the hiring process in 1996 and 2005, we used the China Health and Nutrition Survey (CHNS) questionnaire (1997 data, pooled data of 2004 and 2006) by referring to Johnson (1983) and Mohanty (1998). Empirical results of the 1996 sample reveal that male workers generally receive less favorable treatment and consequently enjoy a lower average employment probability than female workers. However, approximately a decade after the enactment of the labor law, the 2005 sample shows that male workers generally enjoy preferential treatment over female workers with otherwise identical worker characteristics. Our empirical results suggest that an increase in the education level of females, in the employment probability of females aged 25 and younger, and in the employment probability of females working in the government sector may prove effective in eliminating employment discrimination between males and females.

Performance Characteristics and Temperature Compensation Method of Fluid Property Sensor Based on Tuning-Fork Technology

Fluid property sensor (FPS) based on tuning-fork technology is applied to the measurement of the contaminant level of lubricant oil. The measuring principle of FPS sensor is derived and proved together with its resolution. The performance characteristics of the FPS sensor, such as sensitivity coefficient, resolution, and quality factor, are analyzed. A temperature compensation method is proposed to eliminate the temperature-dependence of the measuring parameters, and its validity is investigated by numerical simulation of sensitivity, oscillating frequency, and dielectric constant. The values of purification efficiency obtained using microwave and without microwave are compared experimentally

CBS promoter hypermethylation increases the risk of hypertension and stroke

OBJECTIVES: Cystathionine β-synthase is a major enzyme in the metabolism of plasma homocysteine. Hyperhomocysteinemia is positively associated with hypertension and stroke. The present study was performed to examine the possible effects of Cystathionine β-synthase promoter methylation on the development of hypertension and stroke. METHODS: Using quantitative methylation-specific PCR, we determined the Cystathionine β-synthase methylation levels in 218 healthy individuals and 132 and 243 age- and gender-matched stroke and hypertensive patients, respectively. The relative changes in Cystathionine β-synthase promoter methylation were analyzed using the 2- ΔΔCt method. The percent of the methylated reference of Cystathionine β-synthase was used to represent the Cystathionine β-synthase promoter methylation levels. RESULTS: In this study, the Cystathionine β-synthase promoter methylation levels of hypertensive and stroke participants were both higher than that of the healthy individuals (median percentages of the methylated reference were 50.61%, 38.05% and 30.53%, respectively, all p<0.001). Multivariable analysis showed that Cystathionine β-synthase promoter hypermethylation increased the risk of hypertension [odds ratio, OR (95% confidence interval, CI)=1.035 (1.025–1.045)] and stroke [OR (95% CI)=1.015 (1.003–1.028)]. The area under the curve of Cystathionine β-synthase promoter methylation was 0.844 (95% CI: 0.796–0.892) in male patients with hypertension and 0.722 (95% CI: 0.653–0.799) in male patients with stroke. CONCLUSION: Cystathionine β-synthase promoter hypermethylation increases the risk of hypertension and stroke, especially in male patients

FOLFOXIRI plus cetuximab as conversion therapy for unresectable RAS/BRAF wild-type left-sided colorectal cancer with liver-limited metastases: a prospective dual-center pilot study

PurposeTo explore the efficacy and safety of FOLFOXIRI plus cetuximab regimen as conversion therapy for patients with unresectable RAS/BRAF wild-type colorectal liver-limited metastases (CLM).Patients and methodsThis was a dual-center, phase II trial with the rate of no evidence of disease (NED) achieved as the primary endpoint. All enrolled patients with initially unresectable left-sided RAS/BRAF wild-type colorectal liver-limited metastases received a modified FOLFOXIRI plus cetuximab regimen as conversion therapy.ResultsBetween October 2019 and October 2021, fifteen patients were enrolled. Nine patients (60%) achieved NED. The overall response rate (ORR) was 92.9%, and the disease control rate (DCR) was 100%. The median relapse‐free survival (RFS) was 9 (95% CI: 0–20.7) months. The median progression-free survival (PFS) was 13.0 months (95% CI: 5.7-20.5), and the median overall survival (OS) was not reached. The most frequently occurring grade 3-4 adverse events were neutropenia (20%), peripheral neurotoxicity (13.3%), diarrhea (6.7%), and rash acneiform (6.7%).ConclusionThe FOLFOXIRI plus cetuximab regimen displayed tolerable toxicity and promising anti-tumor activity in terms of the rate of NED achieved and response rate in patients with initially unresectable left-sided RAS/BRAF wild-type CLM. This regimen merits further investigation
