The Color of Medicine
Diana Salinas
Medical Student Research Journal , 2013,
Abstract: "I will not permit considerations of religion, nationality, race, gender, politics, socioeconomic standing, or sexual orientation to intervene between my duty and my patient." This bullet point from the physician's oath is engraved around the margins to remind us that as physicians we should treat and care for each patient equally and in an unbiased manner, but at the same time understand that universal treatment plan will not apply to all patients.
An interview with Diana from Libya
Diana
International Journal of Inclusive Democracy , 2011,
Abstract: IJID Note:The interviewer will be referred below as JR and the interviewee as DL. Both the interviewer as well as the interviewee preferred not to reveal publicly their names for security reasons.JR’s Notes:In the 1980s, when Gaddafi’s policies veered to the left and nationalization of the economy became widespread, Diana father’s business was severely affected. So her own background is not what one might expect of someone who now is speaking up passionately against the NATO assault on Libya…Unfortunately, most mainstream western journalists seem interested only in hearing from anti-Gaddafi Libyans. So it is the fact that westerners continue to get a one-sided picture of Libya which helps support the case for NATO bombing. Here’s another side to the story…

Marriages, Polygamous, Early Fertility and Development in Congo  [PDF]
Diana Loubaki
Journal of Human Resource and Sustainability Studies (JHRSS) , 2017, DOI: 10.4236/jhrss.2017.53018
Abstract: This article uses endogenous growth theory to show that, both education and labor force participation of women are crucial mechanics of economic development. In an economic environment that prevailing polygamous and early fertility which yields inequalities among women, unemployed labor force is due to difficulties to ensure education for all the children born from different mothers. Thus increases of poverty create a feedback effect since the children’s off-springs become also parental financial support. Indeed, introducing moral hazard and corruption in the economy due to absence of skills, thus information hold is not revealed in order to win money to support the big family. The article also shows that, social inheritance rule is modified, i.e., it may decrease a lot and yield to poverty trap and famine zone or may increase a lot and reach the highest levels or may converge depending on parental polygamous degree or remain equal to the parental status. Consequently, this article provides development foundations focused on women social promotion for development take-off in poorest countries.
Adsorción de arsénico en zeolita natural pretratada con óxidos de magnesio
MEJíA-ZAMUDIO, Flérida;VALENZUELA-GARCíA, Jesús L.;AGUAYO-SALINAS, Salvador;MEZA-FIGUEROA, Diana;
Revista internacional de contaminación ambiental , 2009,
Abstract: a methodology was developed to modify a natural zeolite (chabazite) with magnesium oxide in order to remove arsenic (as+5) from water for human consumption. it is proposed a magnesium oxide while regarded as an efficient adsorbent for removing metals in water. x-ray diffraction analyses show significant changes in the chabazite due to the presence of oxides and amorphous hydroxides incorporated during the pretreatment. experimental design results show an efficiency greater than 90 % of as+5 adsorbed in five minutes. the results indicate that the most significant variables affecting the adsorption of as+5 are the initial concentration of as and the solid/liquid (s/l) ratio. experimental data fitted better to freundlich isotherm with a 20.17 mg/g adsorption capability.
ADSORCIóN DE ARSéNICO EN ZEOLITA NATURAL PRETRATADA CON óXIDOS DE MAGNESIO
Flérida MEJíA-ZAMUDIO,Jesús L. VALENZUELA-GARCíA,Salvador AGUAYO-SALINAS,Diana MEZA-FIGUEROA
Revista internacional de contaminación ambiental , 2009,
Abstract: Se desarrolló una metodología para pretratar una zeolita natural (chabazita) con óxido de magnesio para remover arsénico (As+5) en agua de consumo humano. Se propone un tratamiento con óxido de magnesio por considerarse un adsorbente eficiente para remoción de metales en agua. El análisis de difracción de rayos X muestra cambios significativos en la chabazita debido a la presencia de óxidos e hidróxidos amorfos incorporados durante el pretratamiento. Los resultados del dise o experimental muestran una eficiencia superior a 90 % de As+5 adsorbido en un tiempo de cinco minutos. Los resultados indican que las variables más significativas que afectan la adsorción de As+5 son la concentración inicial de As y la relación sólido/líquido (S/L). Los datos experimentales se ajustan de mejor forma a la isoterma de Freundlich, con lo que se obtiene una capacidad de adsorción de 20.17 mg/g.
How Behavioral Constraints May Determine Optimal Sensory Representations
Emilio Salinas
PLOS Biology , 2012, DOI: 10.1371/journal.pbio.0040387
Abstract: The sensory-triggered activity of a neuron is typically characterized in terms of a tuning curve, which describes the neuron's average response as a function of a parameter that characterizes a physical stimulus. What determines the shapes of tuning curves in a neuronal population? Previous theoretical studies and related experiments suggest that many response characteristics of sensory neurons are optimal for encoding stimulus-related information. This notion, however, does not explain the two general types of tuning profiles that are commonly observed: unimodal and monotonic. Here I quantify the efficacy of a set of tuning curves according to the possible downstream motor responses that can be constructed from them. Curves that are optimal in this sense may have monotonic or nonmonotonic profiles, where the proportion of monotonic curves and the optimal tuning-curve width depend on the general properties of the target downstream functions. This dependence explains intriguing features of visual cells that are sensitive to binocular disparity and of neurons tuned to echo delay in bats. The numerical results suggest that optimal sensory tuning curves are shaped not only by stimulus statistics and signal-to-noise properties but also according to their impact on downstream neural circuits and, ultimately, on behavior.
Context-dependent selection of visuomotor maps
Emilio Salinas
BMC Neuroscience , 2004, DOI: 10.1186/1471-2202-5-47
Abstract: By means of three hypothetical visuomotor tasks, I study a class of neural network models in which any one of several possible stimulus-response maps or rules can be selected according to context. The underlying mechanism based on gain modulation has three key features: (1) modulating the sensory responses is equivalent to switching on or off different subpopulations of neurons, (2) context does not need to be represented continuously, although this is advantageous for generalization, and (3) context-dependent selection is independent of the discriminability of the stimuli. In all cases, the contextual cues can quickly turn on or off a sensory-motor map, effectively changing the functional connectivity between inputs and outputs in the networks.The modulation of sensory-triggered activity by proprioceptive signals such as eye or head position is regarded as a general mechanism for performing coordinate transformations in vision. The present results generalize this mechanism to situations where the modulatory quantity and the input-output relationships that it selects are arbitrary. The model predicts that sensory responses that are nonlinearly modulated by arbitrary context signals should be found in behavioral situations that involve choosing or switching between multiple sensory-motor maps. Because any relevant circumstancial information can be part of the context, this mechanism may partly explain the complex and rich behavioral repertoire of higher organisms.The concept of a direct, one-to-one association between a sensory stimulus and a motor response has been strongly influential in neuroscience [1]. Such associations may be quite complex; for instance, monkeys can learn visuomotor mappings based on arbitrary rules [2-4]. But from a mechanistic point of view, it is their flexibility which is remarkable. Humans and other mammals react to a given stimulus in drastically different ways depending on the context [1,5-7]. What is the neural basis for this? How do cu
Colonialidad, Modernidad y representación en el cine latinoamericano contemporáneo: De Memorias del subdesarrollo a Pizza, Birra, Faso
Salinas,Claudio;
Aisthesis , 2012, DOI: 10.4067/S0718-71812012000100008
Abstract: the following paper aims to review and analyze how latin america's colonialism and modernity have been represented, built and interrogated in two major films of regional contemporary cinema: memorias del subdesarrollo (memories of underdevelopment) cuba, 1968 and pizza, birra, faso (pizza, beer, fag), argentina, 1998. we have two questions to answer: what images of coloniality and modernity are pictured in these films? how are ?coloniality? and ?modernity? articulated in the selected films?
