Development of Multiscale Spectro-microscopic Imaging System and Its Applications

A novel multi-modality spectro-microscopic system that combines far-field interferometry based optical microscopy imaging techniques (differential interference contrast microscopy and cross-polarized light microscopy), total internal reflection microscopy (total internal reflection fluorescence and scattering microscopy) and confocal spectroscopy (Raman spectroscopy and photoluminescence spectroscopy) is developed. Home-built post treatment stages (thermal annealing stage and solvent annealing stage) are integrated into the system to realize in situ measurements. Departing from conventional characterization methods in materials science mostly focused on structures on one length scale, the in situ multi-modality characterization system aims to uncover the structural information from the molecular level to the mesoscale. Applications of the system on the characterization of photoactive layers of bulk heterojunction solar cell, two-dimensional materials, gold nanoparticles, fabricated gold nanoparticle arrays and cells samples are shown in this dissertation

Women underrepresentation at the workplace: a case study in the Chinese pharmaceutical industry

JEL Classification: J42, J71This thesis examines how the phenomenon of women’s numerical underrepresentation is perceived in the pharmaceutical sales industry in China. Previous studies have suggested that sex-differentiated perceptions and organizational factors may contribute to gender underrepresentation. Yet it is not well understood how these elements connect to foster women underrepresentation in everyday workplaces in the Chinese context. Through interviewing 18 Chinese employees at a joint-venture pharmaceutical sales company, the analysis sheds light on the job characteristics and people attitudes at the workplace. The analysis reveal that job requirements of pharmaceutical sales bring pressure of work family balance, while male colleagues and even female salespeople themselves are (un)consciously reproducing sales occupation’s masculine cultures. The findings suggest that initiatives sponsored at different organizational ladders have reinforced the “status quo” – in few words, have helped to maintain existing systems of gender differences.Esta tese estuda como o fenómeno da sub-representação numérica das mulheres é percebido na indústria farmacêutica na China. Os estudos anteriores têm sugerido que as perceções diferenciadas quanto ao sexo e os fatores organizacionais podem contribuir para a sub-representação de género. Contudo, ainda não se compreende bem como estes elementos se ligam para fomentar a sub-representação das mulheres no dia-a-dia no local de trabalho no contexto chinês. Com base em 18 entrevistas a trabalhadores chineses num consórcio internacional na área da indústria farmacêutica, a análise destaca as características do posto de trabalho e as atitudes individuais. As análises revelam que as exigências profissionais do delegado de informação médica não promovem o equilíbrio entre trabalho e família, enquanto os colegas do sexo masculino e até mesmo os delegados de sexo feminino (in)conscientemente reproduzem a cultura da profissão masculina de vendedor. Os resultados sugerem que as iniciativas promovidas em diferentes níveis hierárquicos têm reforçado o “status quo” – em poucas palavras, líderes e colaboradores têm ajudado a manter o sistema atual de diferenças de género

On Locality of Schmidt-Correlated States

We review some results on the equivalence of quantum states under local unitary transformations (LUT). In particular, the classification of two-qubit Schmidt correlated (SC) states under LUT is investigated. By presenting the standard form of quantum states under LUT, the sufficient and necessary conditions of whether two different SC states are local unitary equivalent are provided. The correlations of SC states are also discussed.Comment: 14 page

Discovery and Testimony of Unretained Experts: Creating a Clear and Equitable Standard to Govern Compliance With Subpoenas

Hearing impairment is known to be one of the most frequent sensory impairments. This condition is known to be a hidden disorder which is under recognised and under treated all around the world. The World Health Organisation (WHO) estimates suggest that there are over 275 million people with hearing impairment and 80% of them living in low and middle income countries. Moreover, the estimates suggest that incidence and prevalence of hearing loss and also the number of people with hearing loss accessing services varies considerably across countries. This rises the need for health promotion (or public awareness campaigns) directed to increase awareness and education of hearing loss and hearing healthcare. This paper provides brief discussion on ‘Stories and storytelling’, ‘Cross-culture and cross-cultural communication’ and ‘Health promotion and cultural sensitivity’. The central focus of this paper is to highlight the applications of storytelling in different cultural context in health promotion, particularly to hearing loss public awareness campaigns

cis-Bis(1,10-phenanthroline-κ2 N,N′)bis­(thio­cyanato-κN)magnesium(II)

The title compound, [Mg(NCS)2(C12H8N2)2], has been synthesized from the hydro­thermal reaction of MgCl2, KSCN, 1,10-phenanthroline and H2O. Its structure is isotypic with the MnII, FeII, CoII, NiII, CuII and ZnII analogues. The MgII cation has a slightly distorted octa­hedral geometry containing four N atoms from two 1,10-phenanthroline mol­ecules and two N atoms from two thio­cyanate anions. The asymmetric unit contains one-half mol­ecule, and the complete complex has 2 symmetry

Production of proton-rich nuclei around Z=84-90 in fusion-evaporation reactions

Within the framework of the dinuclear system model, production cross sections of proton-rich nuclei with charged numbers of Z=84-90 are investigated systematically. Possible combinations with the $^{28}$Si, $^{32}$S, $^{40}$Ar bombarding the target nuclides $^{165}$Ho, $^{169}$Tm, $^{170-174}$Yb, $^{175,176}$Lu, $^{174,176-180}$Hf and $^{181}$Ta are analyzed thoroughly. The optimal excitation energies and evaporation channels are proposed to produce the proton-rich nuclei. The systems are feasible to be constructed in experiments. It is found that the neutron shell closure of N=126 is of importance during the evaporation of neutrons. The experimental excitation functions in the $^{40}$Ar induced reactions can be nicely reproduced. The charged particle evaporation is comparable with neutrons in cooling the excited proton-rich nuclei, in particular for the channels with $\alpha$ and proton evaporation. The production cross section increases with the mass asymmetry of colliding systems because of the decrease of the inner fusion barrier. The channels with pure neutron evaporation depend on the isotopic targets. But it is different for the channels with charged particles and more sensitive to the odd-even effect.Comment: 15 pages, 10 figures. arXiv admin note: text overlap with arXiv:0803.1117, arXiv:0707.258
