Policies for High-Skilled vs. Low-Skilled Migration inNorth America  [PDF]
Camelia Tigau
Open Journal of Political Science (OJPS) , 2013, DOI: 10.4236/ojps.2013.34022
Abstract:

High-skilled migration has always been given priority and even encouraged by international and national policy. At the same, international agreements for low-skilled migration tend to restrict it. Human capital is considered valuable according to educational levels and working abilities, which puts undocumented migrants in a difficult economic position. The NAFTA area is no exception: while the migration of professionals is given priority by mechanisms like the TN and H1 visas, there is still no agreement to relieve the situation of unskilled immigration across the border from Mexico to the US and Canada in search of a better life. At the same time, migration between Canada and the US is much freer, even though professionals are also given priority; after NAFTA, Canada has even experienced brain drain to the US. The main question is how to reduce unfair differences in policies that prioritize the mobility of certain individuals based on their qualifications. Method: This paper analyzes and compares NAFTA’s impact on policies for high- vs. low-skilled migration. It also uses the author’s ethnographic studies to express the view of migrants on how human capital should be managed internationally.

Track 2 Innovation Agents in North America: The View from Mexico
Tigau, Camelia Nicoleta;
Norteamérica , 2008,
Abstract: economic disparities in north america are confirmed by the analysis of innovation infrastructures, especially when it comes to ngos acting as public-private networking agents. ngos and civic associations dedicated to innovation have a tradition in the u.s. and canada, while in mexico they have recently launched basic networking and brokering activities. given the unequal context of innovation institutions in north america that checks the possibility of a fair comparison, this paper provides a within-case analysis of the arco alliance in mexico, a hybrid partnership involving public, private, and civic organizations, meant to promote regional innovation based on an oecd ideology. additionally, policy-tracing methodology is used to analyze the adequacy of the oecd innovation model when applied to the mexican situation.
Effects of 17β-Estradiol on Growth, Primary Metabolism, Phenylpropanoid-Flavonoid Pathways and Pathogen Resistance in Arabidopsis thaliana  [PDF]

Abstract: Mammalian sex hormones are spread in the environment from natural and anthropogenic sources. In the present study, the effect of estradiol on Arabidopsis thaliana growth primary metabolism, phenylpropanoid and flavonoid pathways and pathogen resistance were investigated. Treatments of Arabidopsis plants with 10 and 100 nM 17β-estradiol resulted in enhanced root growth and shoot biomass. In addition, treated plants had an increased rate of photosynthesis with a concomitant increase in carbohydrate and protein accumulation. Plants exposed to higher concentrations of 17β-estradiol (10 μM) had significantly lower root growth, biomass, photosynthesis rate, primary metabolite and phenylpropanoid and flavonoid contents indicating a toxic effect of estradiol. Treatments with increasing estradiol concentrations (10 nM, 100 nM and 10 μM) resulted in the downregulation of phenylpropanoid-flavonoid pathway genes (PAL1, PAL4, CHI and ANS) and subsequent decreased accumulation of phenolics, flavonoids and anthocyanins. Estradiol-treated plants were inoculated with Pseudomonas syringae pv. Tomato DC3000 and basal resistance was determined. Estradiol treatments rendered plants susceptible to the pathogen, thus compromising the plant defense mechanisms. These results indicate that at low concentrations, estradiol functions as a biostimulant of growth, yield and primary metabolism of Arabidopsis. However, estradiol functions as a potential transcriptional regulator of the phenylpropanoid pathway genes in Arabidopsis, having a negative effect on
Alleviation of Drought Stress in Arabidopsis thaliana by 17β-Estradiol Application  [PDF]
Pallavi Upadhyay, Camelia Maier
American Journal of Plant Sciences (AJPS) , 2016, DOI: 10.4236/ajps.2016.714186
Abstract: Animal steroidal hormones, including estrogens, are being introduced into the agricultural soil and water supply from increased pharmaceutical and farm waste. Considering the current levels of xenoestrogen contamination of plant environments in view of the climate change induced drought conditions, this study was designed to understand the effect of estradiol (ES) application on Arabidopsis drought stress responses. Estradiol treatment (10 nM, 100 nM) of plants subjected to drought stress conditions by withholding water for 7 days resulted in increased tolerance to drought stress reflected in the significantly higher plant survival rates of 74% and 78%, respectively compared to control plants’ survival rates of 36% (no treatment) and 40% (mock treatment). Estradiol application significantly increased the content of glutathione, proline and H2O2 and significantly enhanced the transcription of the stress responsive genes GSTU3, GER5, HSP101, and HSP70b. A high concentration of ES (10 μM) did not protect plants against drought stress and proved to be toxic. These results provide new insight into the effect of ES on drought-stress responses in Arabidopsis with possible practical agricultural applications regarding the effect of environmental estrogens on crop plants.
EXPLICIT APPLICATION OF SWANEPOEL’S METHOD FOR THE ANALYSIS OF Sb2O3 FILMS
SIMONA CONDURACHE-BOTA,NICOLAE TIGAU,ROMANA DRASOVEAN
Journal of Science and Arts , 2010,
Abstract: Swanepoel’s method can be applied successfully for the determination of essential optical parameters for films exhibiting interference pattern-type of optical transmission spectra, such those made of antimony trioxide deposited on glass. Refractive index dispersion, absorption spectrum, the real and the imaginary parts of the dielectric constant and the optical conductivity are some of the important features that can be determined by using this valuable method. Also, calculation of films’ thicknesses can be inferred by using Swanepoel’s method. Still, care has to be taken concerning the estimation of film’s thickness from pairs of transmission maxima and/or minima, since important variations may occurs from several computations based on the same spectrum. This article makes a detailed presentation of the application of the mentioned method for the determination of some of the optical features of vacuum-deposited Sb2O3 films.

NICOLAE TIGAU,SIMONA CONDURACHE-BOTA,ROMANA DRASOVEAN
Journal of Science and Arts , 2010,
Abstract: Thin films of SbS have been deposited by vacuum evaporation technique onto highly cleaned glass substrates under vacuum of the order 10 torr. The structure of the films was determined by their X-ray diffraction patterns and AFM images. Transmittance measurements in the wavelength range (500-1100 nm) were used to compute the refractive index using the Swanepoel’s method. The optical properties of these thin films have been investigation from transmission spectra by using Wemple-DiDomenico single oscillator model. These films posed, in general good transparency, exhibiting an interference pattern. The wavelength dependence of refractive index and extinction coefficient of these films has been reported.
STRUCTURAL AND ELECTRICAL CHARACTERIZATION OF COBALT OXIDE SEMICONDUCTORS
ROMANA DRASOVEAN,SIMONA CONDURACHE-BOTA,NICOLAE TIGAU
Journal of Science and Arts , 2010,
Abstract: In this work, it was investigated electrical and structural properties of porous cobalt oxide film that was grown on glass substrate via sol-gel method. The electrical parameters measurement was made using the Van der Pauw technique. Structural and morphological studies have been carried out by means of SEM, and AFM. As-deposited cobalt oxide films showed amorphous nature as confirmed from X-ray diffraction studies. It was shown that annealing influences the grain size of the nanosized cobalt oxide grains. Changes in direct band gap energy and electrical resistivity of as-deposited cobalt oxide films were confirmed after annealing. Spherical grains were uniformly distributed over the substrate surface. In thicker films appears an improvement in crystallinity and grain size which induce higher conductivity. The conductivity of cobalt oxide based films exhibits ρ values between 10-3-103 -1cm-1, depending on the conditions of the annealing.

Impact of Integrated Marketing Communication on Consumer Behaviour: Effects on Consumer Decision – Making Process
Camelia Mihart
International Journal of Marketing Studies , 2012, DOI: 10.5539/ijms.v4n2p121
Abstract: Integrated marketing communication (IMC) is one of the most controversial areas of research, the concept marking a constant progress from the simple coordinating of promotional tools to a complex strategic process. Further to the evolution of modern marketing, where IMC has become a major way of achievement the objectives of a company, there is a need to identify opportunities to increase its impact on consumer behaviour. Therefore, is of interest, the relatively recent approach found in the literature, according to which IMC works specifically through all the four classic elements of the marketing mix: product, price, placement and marketing communications. In this context, this paper intends to clarify some aspects regarding the effects of IMC on the consumer behaviour, materialized in the consumer decision- making process.
THEORETICAL AND PRACTICAL ASPECTS REGARDING CONSENT, AS VALIDITY CONDITION OF THE CIVIL ACT
Camelia Stanciulescu
Lex et Scientia , 2008,
Abstract: According to article 953 of the Civil Code, “consent is invalid when it is granted by mistake, obtained through violence and fraud”. Besides the defects of consent mentioned by the legal provisions, we must point out, in certain conditions, injury, which represents a material prejudice that one of the contracting parties suffers, because of the obvious disproportion in value, emerging right at the moment of concluding the contract, between the performance that it undertook to provide and the performance that it was entitled to receive in exchange1.An error consists in a situation when a person has an erroneous image of reality, considering that what is false is true, or that what is true is false2. Consent must represent the perfect agreement between the wills of the persons that are bound by the legal relationship.
