Facts and Perceptions Regarding Software Measurement in Education and in Practice: Preliminary Results  [PDF]
Mónica Villavicencio, Alain Abran
Journal of Software Engineering and Applications (JSEA) , 2011, DOI: 10.4236/jsea.2011.44025
Abstract: How is software measurement addressed in undergraduate and graduate programs in universities? Do organizations consider that the graduating students they hire have an adequate knowledge of software measurement? To answer these and related questions, a survey was administered to participants who attended the IWSM-MENSURA 2010 conference in Stuttgart, Germany. Forty-seven of the 69 conference participants (including software development practitioners, software measurement consultants, university professors, and graduate students) took part in the survey. The results indicate that software measurement topics are: 1) covered mostly at the graduate level and not at the undergraduate level, and 2) not mandatory. Graduate students and professors consider that, of the measurement topics covered in university curricula, specific topics, such as measures for the requirements phase, and measurement techniques and tools, receive more attention in the academic context. A common observation of the practitioners who participated in the survey was that students hired as new employees bring limited software measurement-related knowledge to their organizations. Discussion of the findings and directions for future research are presented.
Relevance of Epistemological Pluralism for Resource Management Policies  [PDF]
Mónica Gómez Salazar
Open Journal of Philosophy (OJPP) , 2015, DOI: 10.4236/ojpp.2015.56039
Abstract: The common believe of a single successful form of knowing the reality is misleading. A brief analysis of many human activities reveals a pluralistic perspective of several coexisting conceptual schemes that underlie the form in which women and men know and constitute the world in which we live. Here, I will discuss the necessity of taking seriously this pluralistic perspective when developing conceptual frameworks of human activities. As an example of great interest and importance, I will consider the case of resource management that has to contemplate the conservation and the response of ecosystems to human activities that may lead to irreversible damage. Ecosystems’ activity occurs over a wide range of space and time scales and, hence, policies and proposals of solutions to ecological problems should avoid narrow and monochromatic approaches. Specifically, the Pemon perspective of fire is a good example to show that for more robust and flexible resource management we need the knowledge and experience of different cultural and disciplinary groups.
A Matching Model on the Use of Immigrant Social Networks and Referral Hiring  [PDF]
Mónica García-Pérez
Theoretical Economics Letters (TEL) , 2012, DOI: 10.4236/tel.2012.24070
Abstract: Using a simple search model, with urn-ball derived matching function, this paper investigates the effect of firm owner’s and coworkers’ nativity on hiring patterns and wages. In the model, social networks reduce search frictions and wages are derived endogenously as a function of the efficiency of the social ties of current employees. As a result, individuals with more efficient connections tend to receive higher wages and lower unemployment rate. However, because this efficiency depends on matching with same-type owners and coworkers, there is also a differential effect among workers’ wages in the same firm. This analysis highlights the potential importance of social connections and social capital for understanding employment opportunities and wage differentials between these groups.
Assessing spatial genetic structure from molecular marker data via principal component analyses: A case study in a Prosopis sp. forest  [PDF]
Ingrid Teich, Aníbal Verga, Mónica Balzarini
Advances in Bioscience and Biotechnology (ABB) , 2014, DOI: 10.4236/abb.2014.52013
Abstract:

Advances in genotyping technology, such as molecular markers, have noticeably improved our capacity to characterize genomes at multiple loci. Concomitantly, the methodological framework to analyze genetic data has expanded, and keeping abreast with the latest statistical developments to analyze molecular marker data in the context of spatial genetics has become a difficult task. Most methods in spatial statistics are devoted to univariate data whereas the nature of molecular marker data is highly dimensional. Multivariate methods are aimed at finding proximities between entities characterized by multiple variables by summarizing information in few synthetic variables. In particular, Principal Component analysis (PCA) has been used to study genetic structure of geo-referenced allele frequency profiles, incorporating spatial information with a posteriori analysis. Conversely, the recently developed spatially restricted PCA (sPCA) explicitly includes spatial data in the optimization criterion. In this work, we compared the results of the application of PCA and sPCA in the study of the spatial genetic structure at fine scale of a Prosopis flexuosa and P. chilensis hybrid swarm. Data consisted in the genetic characterization of 87 trees sampled in Córdoba, Argentina and genotyped at six microsatellites, which yielded 72 alleles. As expected, principal components explained more variance than sPCA components, but were less spatially autocorrelated. The maps obtained by the interpolation of sPC1 values allowed a better visualization of a patchy spatial pattern of genetic variability than the PC1 synthetic map. We also proposed a PC-sPC scatter plot of allele loadings to better understand the allele contributions to spatial genetic variability.

Recognition in the Communication Processes of Diverse Young the Experience of Living in a Park in the City of Cali  [PDF]

Abstract: Artisan Park La Loma de la Cruz, is a park located in a suburb of the city of Cali, a place where different groups converge youth from youth cultures. The park is a place for meeting, socializing, communication practices through which young people interact and build relationships. The park is set up as a stage of “coexistence” in which rockers, punks, emos, skaters and members of the LGBTI community stay together and share the same dwelling place (Figure 1). In the worlds of life of these young people, the words in different languages are a part of his being and his feelings, hence the affectations of joy and sadness, as defined by Spinoza (1980)1, are a way of weaving links and establish relationships communication. It is also possible to identify forms of recognition, Honneth’s way, recognition of love and solidarity2. These forms of recognition collide when young people, relate to the adult world, in the park, are made by artisans, police and neighbors. From the adult world, the form of contempt is evident in the rejection of the young by their expressions, especially those with expressing his affectations manifest. If young people recognize the existence of other people, as well as their own differences in the way they think, if they recognize the action in their own inter-subjective relationships and in the same way they construct a “we”, we would be spectators of new ways of being together; of ethical and political linking which go through new ways of living together and in which the sense and the shared meaning of life are negotiated that show a way of understanding in communication.
Co-infec??o HIV/tuberculose: necessidade de uma vigilancia mais efetiva
Lima,Mnica M.;
Revista de Saúde Pública , 1997, DOI: 10.1590/S0034-89101997000300001
Abstract: the increasing endemicity of tuberculosis resulting from causes such as immigration, poverty, a declining public health infrastructure and co-infection by hiv/mycobacterium tuberculosis, is leading to a change in tuberculosis control programmes. one of the main reasons for the resurgence of tuberculosis is hiv infection - the risk of tuberculosis is greater in hiv patients than in the majority of the population as can be seen from numerous research projects. the need for systematic testing for hiv infection in all tuberculosis patients by undertaking confidential hiv tests on admission to a tuberculosis programme is brought out. this measure would increase the number of cases diagnosed and provide data for better surveillance of the co-infection.
Entanglements of right whales, Eubalaena australis (Cetacea, Mysticeti), in the 2010 breeding season in Santa Catarina state, Brazil
Mnica Pontalti,Mnica Danielski
Biotemas , 2011,
Abstract: Right whales (Eubalaena australis) have been suffering with anthropogenic activities such as pollution, marine traffic and entanglement in fishing nets. The entanglement of right whales grows each breeding season on the southern coast of Santa Catarina state, and can cause strands and even death. During the 2010 breeding season, six entanglements among immature and adult whales were recorded. In most of the cases, the whales kept swimming slowly and didn’t want to approximate the whale watching boat. Fishing activities in the area during the right whale breeding season need to be regularized to avoid conflicts and injuries to the whales.
Selection of Maize Genotypes with Tolerance to Osmotic Stress Associated with Salinity  [PDF]
Mónica B. Collado, Mónica B. Aulicino, Miguel J. Arturi, María del C. Molina
Agricultural Sciences (AS) , 2016, DOI: 10.4236/as.2016.72008
Abstract: Thirteen different inbred lines in relation to the type of grain and life cycles were characterized by testing for osmotic stress associated with salinity. The identification of tolerant genotypes would be an effective strategy to overcome the saline stress. Osmotic stress reduces immediately the expansion of the roots and young leaves which determine a reduction in the size of the plant. A completely randomized design was adopted to test seedlings under controlled conditions of light and temperature. Two treatments were used: 0 mM NaCl (as control) and 100 mM NaCl. After 15 days of complete salinization, the seedlings were harvested and several morphological traits were measured. The morphological traits of growth were leaf growth (Ar1, Ar2, Ar3 and Ar4), dry masses of shoot and root (SDM and RDM, respectively). Also, traits associated with water economy were registered: leaf water loss (LWL) and relative water content (RWC). The morphological traits were expressed in relative terms, while the traits associated with the economy of water were expressed in absolute terms. Uni and multivariate techniques were applied to identify genotypes with divergent behaviors to osmotic stress tolerance. Also, a Tolerance Index was employed to identify superior genotypes. Four clusters were obtained after applying a Cluster Analysis and Principal Component Analysis (PCA). The genotypes were compared to each other with a test of DMS. The results obtained with different statistical techniques converged. Some variables presented a differential weight classification of genotypes. The morphological traits like RDM, SDM, Ar3, Ar4 and Ar5 were the most discriminating. Tolerance Index allowed to classify genotypes, thus SC2 and AD3 lines were that reached highest value of the index and therefore would be tolerant lines, while AF3 and LP3 had a low index and were seen as sensible.
Generational Mean Analysis of Salt Tolerance during Osmotic Phase in Maize Seedling  [PDF]
Mónica B. Collado, Mónica B. Aulicino, Miguel J. Arturi, María del C. Molina
American Journal of Plant Sciences (AJPS) , 2019, DOI: 10.4236/ajps.2019.104040
Abstract: This study details the nature and magnitude of the genetic effects associated with various quantitative characters (morphological and hydric relations) measured in maize seedlings during the osmotic phase of saline stress (100 mM NaCl). Three lines with differential behavior in salt stress: SC2 (tolerant), AFE (susceptible) and LP3 (moderately tolerant) were used to obtain contrasting crosses (SC2 × AFE) and (SC2 × LP3). An analysis of six generational means (P1, P2, F1, F2, BC1 and BC2) was applied for each cross. First a scaling test was applied and then a three and six-parameter genetic models were used to estimate various genetic components. In none of the traits studied there was evidence of adequacy to the three parameter model, which indicates important epistatic effects in genetic expression. The dominant genetic effects were greater than the additive ones for all the characters evaluated. LG showed positive and significant differences for [h] in both crosses, indicating the presence of hybrid vigor and its possible use in the improvement. Low value of [d] and high of [h] both significant in SC2 × AFE, indicates existence of genes dispersion between the parental lines. While, for the cross SC2 × LP3, the low and significant value of [d] and not significant value of [
Outcomes of the Clean Development Mechanism in Argentina  [PDF]

Abstract: This paper summarizes the results of the implementation of the CDM in Argentina during the first period of commitment of the Kyoto Protocol. From a total of sixty- five projects ideas, forty-four achieved registration under the CDM EB while the rest remained approved at national level (12), under evaluation (2), suspended (5) or rejected (2). Most of the projects focused on the generation of electricity from renewable energy, mainly wind energy and the use of landfill gas and methane for energy. Emissions reductions achieved 33.4% of the expected CERs up to 2012 with strong differences among sectors. Results demonstrated that under the current Argentina’s energy policy framework, the income by the selling of CERs covered less than 6% of the incremental costs for renewable energy projects. A sensitivity analysis to evaluate the impact of CDM in the coverage of incremental costs for renewable energy based on the prices of both the energy in the local market and the CER demonstrated that the best conditions would only cover 15% of those costs. The contribution of CDM to technology transfer in Argentina was minor considering that 45% of the projects qualified as type III where technological learning and capacity building were limited at the level of operation and maintenance of a foreign technology. Domestic and external barriers that prevented a better performance of CDM projects in terms of GHG mitigation, technology transfer and the contribution to a sustainable development were also analyzed.
