Building Intercultural Competence Through Intercultural Competency Certification Of Undergraduate Students

The Intercultural Competency Certificate (CCI in Spanish) designed for the Universidad Popular Automa del Estado de Puebla (UPAEP University) is a theory based comprehensive plan to develop undergraduate students intercultural competence. This Certificate is based in the Developmental Model of Intercultural Sensitivity (DMIS) developed by Milton Bennett (1993) and will be assessed by the Intercultural Development Inventory (IDI) v.3 developed by Bennett & Hammer (Hammer, 2009; Hammer, Bennett, & Wiseman, 2003). The main purpose of the Intercultural Competency Certificate is to develop students intercultural competence at least to the acceptance level of the DMIS continuum. To achieve this goal, the students will have to develop of necessary knowledge, skill and attitudes (Deardorff, 2006). This Certificate proposes to develop attitudes, knowledge and skills through certain activities as learning a new language, take international classes, reflect about intercultural differences, interact with people from other cultures, travel abroad and receive coaching by a professional who will guide them through tailor-make experiences according to the initial level of intercultural competence, measured by the IDI v.3 at the beginning of the Certification

Bacillary Angiomatosis in a HIV-positive Patient with Poor Adherence to Antiretroviral Therapy

Bacillary angiomatosis is a systemic disease caused by Bartonella (B.) henselae and B. quintana. Today it is a rare disease that occurs predominantly in patients with poor adherence to antiretroviral therapy or with late diagnosis of human immunodeficiency virus (HIV). We report on the case of a 40-year-old Caucasian female with HIV-1 and hepatitis B virus (HBV) co-infection diagnosed 17 years ago. She presented to the emergency department with an erythematous, painless nodule located on the left naso-genian fold. In the next few weeks the disease disseminated to the oral and left tarsal mucosa and to the palm of the left hand. The histopathological findings were suggestive of bacillary angiomatosis which was confirmed by polymerase chain reaction (PCR). The patient was treated with clarithromycin 500 mg bid per os for 3 months, with complete remission of the mucocutaneous lesions. Bacillary angiomatosis is a potentially fatal disease. Early diagnosis and treatment are critical in reducing the morbidity and mortality associated with it.</p

Antibody response against selected epitopes in the HIV-1 envelope gp41 ectodomain contributes to reduce viral burden in HIV-1 infected patients

The ectodomain of gp41 is the target of potent binding and neutralizing antibodies (NAbs) and is being explored in new strategies for antibody-based HIV vaccines. Previous studies have suggested that the W164A-3S (3S) and EC26-2A4 (EC26) peptides located in the gp41 ectodomain may be potential HIV vaccine candidates. We assessed 3S- and EC26-specific binding antibody responses and related neutralizing activity in a large panel of chronic HIV-1-infected Portuguese individuals on ART. A similar proportion of participants had antibodies binding to 3S (9.6%) and EC26 (9.9%) peptides but the level of reactivity against 3S was significantly higher compared to EC26, except in the rare patients with double peptide reactivity. The higher antigenicity of 3S was unrelated with disease stage, as assessed by CD4+ T cell counts, but it was directly related with plasma viral load. Most patients that were tested (89.9%, N = 268) showed tier 1 neutralizing activity, the potency being inversely associated with plasma viral load. In the subset of patients that were tested for neutralization of tier 2 isolates, neutralization breadth was inversely correlated with plasma viral load and directly correlated with CD4+ T cell counts. These results are consistent with a role for neutralizing antibodies in controlling viral replication and preventing the decline of CD4+ T lymphocytes. Importantly, in patients with 3S-specific antibodies, neutralizing titers were inversely correlated with viral RNA levels and proviral DNA levels. Moreover, patients with 3S and/or EC26-specific antibodies showed a 1.9-fold higher tier 2 neutralization score than patients without antibodies suggesting that 3S and/or EC26-specific antibodies contribute to neutralization breadth and potency in HIV-1 infected patients. Overall, these results suggest that antibodies targeting the S3 and EC26 epitopes may contribute to reduce viral burden and provide further support for the inclusion of 3S and EC26 epitopes in HIV-1 vaccine candidates.publishersversionpublishe

Contaminated soils and sediments associated with Zn ore metallurgy near the São Francisco River, Minas Gerais (Brazil)

Draining through industrial areas of the Minas Gerais mining state (Brazil), some tributaries of the São Francisco River constitute a potential environmental hazard for this great river and threaten the quality of the regional soils for agriculture and other activities. Extensive geochemistry and mineralogy of sediments, soils and alluvial plains from six selected areas within the Consciência drainage basin close to an important Zn-extraction plant, have been carried out. In this report, detailed mineralogy of those samples and supporting geochemical data are discussed, taking into account their specific climactic and environmental context. Petrographic and electron microprobe characterization of the sand-grained fraction of these materials was complemented by XRD on their finer fraction: the main contaminant minerals are willemite (one of the Zn ores used in the industrial plant) and jarosite, though their contents are quite variable in the studied areas and also with depth; minor amounts of Zn-, Pb-, Cd-, and Mn-bearing mineral phases are also frequent, usually as inclusions in willemite or in polycrystalline clasts, or adsorbed on the finer materials, such as clay minerals and associated Fe-hydroxides. Mineralogical contamination is responsible for high metal contents in the soils and sediments of the areas closer to the plant (e.g. Zn ≫ 2000 mg kg−1 and Cd ≫ 20 mg kg−1, which are the Intervention Values for Industrial Areas) and the greatest contamination risks are related to the more labile phases that circulate throughout the alluvial plains, the shallow sediments and the stream bed. Monitoring the mineral/chemical contamination and its extent also constitutes a useful basis for future proposals to remediate and recover this industrial area in order to decrease medium- and long-term negative impacts of metal contamination on the local and downstream environments

Long-term application of the organic and inorganic pesticides in vineyards: Environmental record of past use

Areas such as Douro Demarcated Region (Portugal), where vineyards are frequently located on steep slopes of narrow valleys, can be particularly sensitive to runoff and erosion processes. These particular conditions are expected to enhance the transport of pollutants, acting as a potential source of contamination to freshwater systems. The intense vine cultivation in this region includes decades of pesticides application, that have resulted in the accumulation of these chemicals and its degradation products in the vineyards soils and sediments. Residues of several pesticides related to agricultural activities were found in soils, with older vineyards showing higher levels of Cu and banned insecticides (such as DDT). The metabolite 4,4-DDE was the compound found at higher levels in soils and in sediments. The relatively high levels in more recent sediments suggest that soils are still a source of contamination. Levels of currently used pesticides were low, which is related with their physicochemical properties, the application period, and climacteric conditions

In this work, we studied the epidemic history and transmission dynamics of HBV genotypes that are endemic in Portugal. HBV pol gene was sequenced from 130 patients followed in Lisbon. HBV genotype A was the most prevalent (n = 54, 41.5%), followed by D (n = 44, 33.8%), and E (n = 32, 24.6%). Spatio-temporal evolutionary dynamics was reconstructed in BEAST using a Bayesian Markov Chain Monte Carlo method, with a GTR nucleotide substitution model, an uncorrelated lognormal relaxed molecular clock model, a Bayesian skyline plot, and a continuous diffusion model. HBV subgenotype D4 was the first to be introduced in Portugal around 1857 (HPD 95% 1699-1931) followed by D3 and A2 a few decades later. HBV genotype E and subgenotype A1 were introduced in Portugal later, almost simultaneously. Our results indicate a very important role of Portugal in the exportation of subgenotypes D4 and A2 to Brazil and Cape Verde, respectively, in the beginning of the XX century. This work clarifies the epidemiological history of HBV in Portugal and provides new insights in the early and global epidemic history of this virus.This work was performed in the context of Rute Marcelino PhD study, whose student’s fellowship (SFRH/BD/99507/2014) was supported by the Portuguese Agency for Scientific Research, Fundação para a Ciência e Tecnologia (FCT), POCH program, Portugal 2020, and European Union/Social European Fund (FSE).

Energy dependence of Cronin momentum in saturation model for p+Ap+A and A+AA+A collisions

We calculate $\sqrt{s}$ dependence of Cronin momentum for $p+A$ and $A+A$ collisions in saturation model. We show that this dependence is consistent with expectation from formula which was obtained using simple dimentional consideration. This can be used to test validity of saturation model (and distinguish among its variants) and measure $x$ dependence of saturation momentum from experimental data.Comment: LaTeX2e, 12 pages, 8 figure

Digital Filter Performance for Zero Crossing Detection in Power Quality Embedded Measurement Systems

Power quality analysis involves the measurement of quantities that characterize the power supply waveforms such as RMS value, frequency, harmonic and inter-harmonic distortion or the presence of transients. The measurement of these quantities is regulated by internationally accepted standards from IEEE or IEC. In particular, for the evaluation of frequency and RMS values, the standard suggests the detection of the waveform zero crossings. Thus, accurate zero crossing detection is of utmost importance in power quality measurements. The undesirable effects of noise, harmonics and transients can be mitigated by filtering of the acquired waveforms, which induces a frequency dependent delay in the processed waveforms. This paper presents a comparative analysis between two types of filters. A comparative analysis is performed between the use of a fixed nominal delay and a frequency corrected delay. Additionally, the effect of the presence of noise and harmonics in the delay compensation is presented
