Measuring Rural Poverty in China: a Case Study Approach

This paper measures rural poverty in Hubei Province and Inner Mongolia in China. The poverty lines we derived by Ravallion's method differ from the official Chinese poverty lines. The official pan-country poverty line underestimates rural poverty in Hubei Province and overestimates rural poverty in Inner Mongolia. Poverty determinants are estimated by Logit as well as Probit models. The study notes that factors such as living in a mountainous area, lack of better irrigation conditions, a large family size, few fixed assets, few land owned and sole dependence on agriculture as a livelihood source would make a rural household more vulnerable to poverty. On the other hand, a rural household whose members are either better educated or trained laborers would statistically be less poor. The growth-redistribution decomposition reveals that for all the three FGT indexes in Hubei province, income growth contributed much to the alleviation of poverty, while the redistribution or inequality effects counteracted the growth effects and worsened poverty. The poverty incidence decomposition results reveal that about one third of the growth effects had been counteracted by the redistribution effects. This implies that future anti-poverty programs should pay more attention to solving the inequality problem in China. Poverty dominance analysis also helps us better understand the poverty situation. It reveals that rural poverty in Inner Mongolia is more severe than that in Hubei, and that poverty incidence in Hubei has lessened from 1997 to 2003, which are the same findings as those drawn from deriving poverty lines.Rural Poverty Line, Poverty Determinants, Growth Redistribution Decomposition, Poverty Dominance, China

Population Ageing, Labour Market Rigidity and Corporate Innovation: Evidence from China

Population ageing leads to labour scarcity and labour market rigidity. Contrary to supply-side economists’ belief that labour market rigidity tends to suppress firm innovation, we provide novel evidence of a positive relationship between population ageing and firm innovation in China. This enhancement effect is greater for firms with higher labour costs, consistent with the argument that labour scarcity encourages labour-saving innovation in response to demographic shifts. In addition, the observed positive effect is particularly pronounced for state-owned enterprises, which are widely acknowledged to be overstaffed with older workers, and firms in industries that pursue Schumpeter-II innovation and engage in more intense research and development. In addition, population ageing helps firms to generate more exploitative (vs. exploratory) innovation. Overall, our findings suggest that firms facing population ageing can adapt their strategies to innovate successfully

Role of endometrial blood flow assessment with color Doppler energy in predicting pregnancy outcome of IVF-ET cycles

This is a prospective study of 182 women (38 yrs or younger) undergoing IVF-ET. Endometrial thickness, echo pattern and blood flow on transvaginal ultrasonography were recorded eight hours prior to hCG administration. The patients were divided into three groups: A (n = 10) with undetectable endometrial blood flow; B (n = 82) with sub-endometrial blood flow; C (n = 90) with both endometrial and sub-endometrial blood flow. According to IVF-ET outcomes, all patients were re-divided into three groups: 1 non-pregnancy (n = 92); 2 intrauterine pregnancy with live fetus (n = 70); 3 others (n = 20 including biochemical pregnancy, embryonic diapause, ectopic pregnancy and miscarriage). Intrauterine pregnancy with live fetus in Group C (62.2%) was much higher than that in Group A and B (0% and 17.1%, p less than or equal to 0.001). The implantation rate (33.2%) was much higher than that in Group A and B (0% and 19.90%, p less than or equal to 0.001). The pulsatility index, resistance index, and S/D of endometrial spiral arteries were 0.1 +/- 0.2, 0.6 +/- 0.1 and 2.5 +/- 0.4 in Group 2, which were much lower than those in Group 1 and Group 3 (p1-2 less than 0.001, p2-3 less than 0.05). The patients with detectable endometrial blood flow had higher clinical pregnancy rates and implantation rates

Research on the Application of Online and Offline Mixed Teaching Mode of Marketing Course Based on the BOPPPS Model

BOPPPS teaching fully integrates the advantages of online self-study and offline courses. This kind of teaching has been widely used in college education, and has proved to have a positive effect on improving students’ ability to solve problems. It also has a significant effect on improving students’ sense of self-efficacy, stimulating learning interest and improving their ability to learn independently in practice. During the implementation of the research, the team explored and practiced the online and offline mixed teaching mode of marketing course with the wisdom tree teaching platform, and built teaching resources for students to learn and discuss on their own, which is a reference for future online mixed teaching

Terahertz spectra revealing the collective excitation mode in charge-density-wave single crystal LuFe2 O4

We report a low-energy collective excitation mode in charge-ordered multiferroic LuFe2O4 via terahertz time domain spectroscopy. Upon cooling from 300 K to 40 K, the central resonance frequency showed a pronounced hardening from 0.85 THz to 1.15 THz. In analogy to the well-known low-energy optical properties of LuFe2O4, we attributed this emerging resonance to the charge-density-wave (CDW) collective excitations. By using the Drude-Lorentz model fitting, we observe the CDW col-lective mode becomes increasingly damped with increasing the temperature. Furthermore, we analyze the kinks of the CDW collective mode at the magnetic transition temperature, which indicates the coupling of spin order with electric polarization
