Procedural Utility in the Work Place, Evidence from Mexico  [PDF]
André Vargas
Theoretical Economics Letters (TEL) , 2014, DOI: 10.4236/tel.2014.49104
Abstract: The concept of Utility usually refers to the satisfaction a person acquires by consuming, in general under circumstances bonded to income, and the price of goods. In a psychological vision of personal well-being, happiness and its components, consider the fact that people can value anything. This notion has led to the study of Procedural Utility, that means people not only value the outcome of something, but also values the process and conditions in which the outcome is achieved. Procedural Utility can be obtained from various economic procedures in which individuals are part of, e.g. Work and consumption among others. Evidence has been found that in the work place the fact of being attached to hierarchy generates negative Procedural Utility because it disrupts psychological precepts that determine happiness, well-being, or utility [1]. In other cases it has been found that the process on how a wage cut is done must be considered [2]. In the light of this phenomena, I’ll discuss the concept of Procedural Utility and analyze empirical evidence for the Mexican case with “Instituto Nacional de Estadistica y Geografía” INEGI’s self-reported well-being survey (BIARE), with the finality to give suggestions on possible applications of processes to improve the worker’s satisfaction.
Facing a Shift in Paradigm at the Bedside?  [PDF]
Borja Vargas, Manuel Varela
International Journal of Clinical Medicine (IJCM) , 2013, DOI: 10.4236/ijcm.2013.41008
Abstract:

Our entire medical framework is based on the concept of disease, understood as a qualitative departure from normality (health) with a structural substrate (lesion), and usually an identifiable cause (aetiology). This paradigm is loaded with problems, some of which are discussed in the text. Nevertheless, we study, diagnose and treat diseases, and while often painfully conscious of the dysfunctionalities of this scheme, we can hardly imagine how we could practice medicine otherwise. However, most of the recent developments in basic sciences, and most notably in Immunology, Genetics and -omics, are inconsistent with this “health/disease” paradigm. The emerging scenario is that of complex networks, more in the spirit of Systems Biology. In these settings the qualitative difference between health and disease loses its meaning, and the whole discourse becomes progressively irreducible to our conventional clinical categories. As clinical research stagnates while basic sciences thrive, this gap is widening, and a change in the prevailing paradigm seems unavoidable. However, all our clinical judgments (including Bayesian reasoning and Evidence Based Medicine) are rooted in the disease/health dichotomy, and one can hardly conceive how they could work without it. The shift in paradigm will not be easy, and certain turmoil is to be expected.

La formación de la conciencia moral en la Universidad Militar Nueva Granada
Vargas Vargas,Jorge Eduardo;
Revista Latinoamericana de Bioética , 2008,
Abstract: this article shows the results from the research "moral conscience formation at nueva granada military university"; these results come from moral development theories proposed by piaget and kohlberg. the diagnosis confronts us to the responsibility that the high educational institutions have, about the people education with a moral of principles, social justice, recognition of the others, and to the search of pedagogical processes that let these developments.
Study of Spider Silk Fibers by Raman Microscopy  [PDF]
Maria Fernanda Vargas-Charry, Carlos Vargas-Hernández
American Journal of Analytical Chemistry (AJAC) , 2018, DOI: 10.4236/ajac.2018.910039
Abstract: Spider silk fibers of species of the genera Araneus, Gasteracantha, and Linothele sericata were studied. The fibers are composed of axial threads and lateral villi, allowing adhesion to surfaces. Raman spectroscopy was used to determine the surface and internal composition of the threads forming the structure. In the three species, the characteristic amino acid peaks of the spider web were found between 2871 and 2975 cm-1, which belong to L-glycine, L-alanine, L-glutamine, and L-proline. The threads are composed of a protective layer mainly composed of amides, alanine, and glycine. The fibrils surrounding the axial fibers consist mainly of amide II (1533 cm-1), which allows adhesion between the thread and the surfaces onto which the spider weaves the web. For the genus Linothele sericata, there is a peak on the surface of this spider web located at 2145 cm-1, which is associated with isonitriles with R-N-C bonds.
Nucleocytoplasmic Gynodioecy  [PDF]
R. Doroteo, J. A. Vargas
Applied Mathematics (AM) , 2013, DOI: 10.4236/am.2013.412226
Abstract:

We study the evolution of a gynodioecious species under mixed-mating through a nucleocytoplasmic male sterility model. We consider two cytoplasmic types and a nuclear locus with two alleles. Here, the interaction between one cytoplasmic type and a recessive nuclear male-sterility factor gives rise to only one female genotype, while the remaining types correspond to hermaphroditic plants. We include two fitness paramaters: the advantageous female fitness t of females relative to that of hermaphrodites; and a silent and dominant cost of restoration, that is, a diminished fitness for plants carrying a dominant restorer gene relative to that of hermaphrodites. The parameter related to the cost of restoration is assumed to be present on outcrossing male fertility only. We find that every population converges to a stable population. We also determine the nature of the attracting stable population, which could be a nucleocytoplasmic polymorphism, a nuclear polymorphism or another population with some genotypes absent. This depends on the position of t with respect to critical values expressed in terms of the other parameters and also on the initial population.

Efecto de la colocación de dispositivos elásticos de hule, en las manos superiores del racimo de banano, sobre la conformación de la mano, el rechazo de frutos y la relación cajas-racimo
Vargas,Alfonso;
Agronomía Costarricense , 2012,
Abstract: the effect of rubber elastic bands (reb) placed on the newly exposed 5 upper hands of the banana bunch was evaluated, from december 2006 to april 2008, on the conformation of the hand, the rejection of fruits and the number of boxes per bunch (‘ratio’). reb lasted 4 to 6 (experiment 1), 6 to 8 (experiments 2 and 3), 6 to 8 and more than 8 (experiment 4) and more than 8 (experiment 5) weeks. bunches without reb were used as the untreated control treatment. in most hands where reb was tested, the curvature of the fruit did not differ (p>0.0934) and the distance (at 90 degrees) from the apex of the inner-row central fruit of the hand to the rachis remained unchanged (p>0.0672), as compared with the control. nevertheless, when in the latter variable differences were expressed (p<0.0414), a reduction of the distance with de use of reb was always observed. the percentage of deformed fruits, except for the highest value (p<0.0389) of some hands in experiments 1, 2, 3 and 5, did not differ between treatments (p>0.0627). the different factors of fruit rejection, especially those related to deformity or injuries by friction between fingers during growth (growth scar), were not affected by the use of reb in any of the experiments where this was evaluated. the number of boxes obtained from the 5 upper hands of the bunch did not allow to show whether reb significantly affected yield.
Reasons And Real Selves
VARGAS,MANUEL;
Ideas y Valores , 2009,
Abstract: most accounts of responsibility begin from either of two prominent points of departure: the idea that an agent must have some characterological or expressive connection to the action, or alternately, the idea that an agent must be in some sense responsive to reasons. here, i will argue that the relation between these two approaches to moral responsibility is much more complicated than is ordinarily assumed. i shall argue that there are reasons to think that one of these views may ultimately collapse into the other, and if not, that there is nevertheless reason to think one of these views has misidentified the features of agency relevant to moral responsibility. the view that follows is one that we might call the primacy of reasons. in the second half of the article i consider whether recent experimental work speaks in favor of the alternative to the primacy of reasons. its proponents argue that it does. i argue that it does not.
