No full textAuthor Institution: Department of Chemistry, University of Arizona; Department of Chemistry, University of WaterlooThe electronic emission spectrum of YH and YD has been investigated in the 690 nm to 3 spectral region using a Fourier transform spectrometer. The YH and YD bands were excited in an yttrium hollow cathode lamp operated with neon gas and a trace of of The observed bands have been classified into three different electronic transitions; and . The transition of YD could not be identified due to its very weak intensity. The rotational analysis of several bands of the transition (up to for YH and for YD) provides improved equilibrium vibrational and rotational constants for the ground state of YH and YD. The excited state is involved in several perturbations

No full textInvolvement of adrenoceptors, dopamine receptors and AMPA receptors in antidepressant-like action of 7-O-ethylfangchinoline in mice
No full textAim: 7-O-ethylfangchinoline (YH-200) is a bisbenzylisoquinoline derivative. The aim of this study was to investigate the antidepressant-like action and underlying mechanisms of YH-200 in mice. Methods: Mice were treated with YH-200 (15, 30, and 60 mg/kg, ig) or tetrandrine (30 and 60 mg/kg, ig) before conducting forced swimming test (FST), tail suspension test (TST), or open field test (OFT). Results: YH-200 (60 mg/kg) significantly decreased the immobility time in both FST and TST, and prolonged the latency to immobility in FST. YH-200 (60 mg/kg) was more potent than the natural bisbenzylisoquinoline alkaloid tetrandrine (60 mg/kg) in FST. Pretreatment with alpha(1)-adrenoceptor antagonist prazosin (1 mg/kg), beta-adrenoceptor antagonist propranolol (2 mg/kg), dopamine D-1/D-5 receptor antagonist SCH23390 (0.05 mg/kg), dopamine D-2/D-3 receptor antagonist haloperidol (0.2 mg/kg) or AMPA receptor antagonist NBQX (10 mg/kg) prevented the antidepressant-like action of YH-200 (60 mg/kg) in FST. In contrast, pretreatment with alpha(2) adrenoceptor antagonist yohimbine (1 mg/kg) augmented the antidepressant-like action of YH-200 (30 mg/kg) in FST. Chronic administration of YH-200 (30 and 60 mg/kg for 14 d) did not produce drug tolerance; instead its antidepressant-like action was strengthened. Chronic administration of YH-200 did not affect the body weight of mice compared to control mice. Conclusion: YH-200 exerts its antidepressant-like action in mice via acting at multi-targets, including alpha(1), alpha(2) and beta-adrenoceptors, D-1/D-5 and D-2 /D-3 receptors, as well as AMPA receptors.National Natural Science Foundation of China [81173031, 81202511, 81302746]SCI(E)PubMed中国科技核心期刊(ISTIC)中国科学引文数据库(CSCD)[email protected]
La doped SrTiO3 thin films on SrLaAlO4 (001) as transparent conductor
No full textTransparent conductors are essential for many optoelectronic applications, and economically viable replacement for the industry standard transparent conductor, indium tin oxide, is in dire need. Electronic structure calculations are performed to confirm that La doping in a band insulator SrTiO3 provides carriers in the conduction band without generating in-gap states and thus La doped SrTiO3 would retain good optical transparency. To realize the computational results, we synthesize La doped SrTiO3 in thin film form and characterize the films. It is demonstrated that 10% La doped SrTiO3 thin films on SrLaAlO4 (001) substrates are indeed transparent conductors with sheet resistance R-S similar to 60 Omega/square and 80% transmission in the visible wavelength range at room temperature.

Labor Migration and Returns to Rural Education in China
No full textThis paper provides an answer to the following question: Why do empirical studies find low returns to schooling in rural China, and yet the schooling rates are high? I find that schooling played a significant role in raising the accessibility of urban formal employment to rural people in the late 1970s and early 1980s in the face of the government's restrictive policy on labor migration from rural to urban areas. The large urban-rural income difference provided a strong incentive for senior high school education. The theory also explains the drop in the senior high school attendance in the mid 1980s.

The Role of Migrant Networks in Labor Migration: The Case of China
No full textUsing recent household survey data from rural China, this article investigates determinants of labor migration, paying special attention to the role of migrant networks. Migrant networks are measured by the number of early migrants from the village, comprised of experienced migrants who continue their migratory activities and return migrants. Observations of early migrants are excluded from regression analyses to enable identification. Results show that experienced migrants have a positive and significant effect on subsequent migration, but return migrants do not. This implies that migrant networks are important, and their effects materialize through practical assistance in the process of migration.

Full responsibility with partial citizenship: Immigrant wives in Taiwan
No full text[[abstract]]The interrelationship between increased ageing and declining fertility is facing many developed countries with challenges, risks and policy debates around care, reproduction and women's rights. This article demonstrates the special case of cross-border marriages and the lives of immigrant wives in Taiwan, with a view to identifying their social needs and hence their prospects for social inclusion. It considers the extent to which these immigrant wives have managed to fulfil the dreams of their own native families and/or satisfy the reproductive demands of their 'in-law' families. Issues of women's social and reproductive role, gender discrimination and the unfulfilled rights and 'partial citizenship' of immigrant wives are discussed. The author argues that immigrant wives carry full responsibility but possess only partial citizenship. The ideology of the spousal sponsorship regime, which makes the application for naturalization extremely difficult, not only increases the vulnerability of immigrant women but violates their human fights.[[note]]SSC
