Poesía niuyorriqueña y narco-cultura: La vida en los márgenes
El mundo de las drogas ocupa un lugar central en la poética desarrollada por la primera generación literaria de puertorriqueños diaspóricos. De enorme potencial contestatario , estas manifestaciones culturales se constituyeron como verdaderos nichos de resistencia frente a los poderes marginalizantes del mainstream estadounidense de la segunda mitad del siglo XX .Fil: López, Alejo.

Measuring the World: Olfaction as a Process Model of Perception
How much does stimulus input shape perception? The common-sense view is that our perceptions are representations of objects and their features and that the stimulus structures the perceptual object. The problem for this view concerns perceptual biases as responsible for distortions and the subjectivity of perceptual experience. These biases are increasingly studied as constitutive factors of brain processes in recent neuroscience. In neural network models the brain is said to cope with the plethora of sensory information by predicting stimulus regularities on the basis of previous experiences. Drawing on this development, this chapter analyses perceptions as processes. Looking at olfaction as a model system, it argues for the need to abandon a stimulus-centred perspective, where smells are thought of as stable percepts, computationally linked to external objects such as odorous molecules. Perception here is presented as a measure of changing signal ratios in an environment informed by expectancy effects from top-down processes
Natural history contributions of the University of Glasgow Exploration Society to Scotland and the World
Expeditions with a natural history focus have been
organised by University of Glasgow staff and
students since the 1930s. The educational benefits of
such expeditions to students have been reported by
Harper
et
al.
(
Journal
of
Biological
Education
51, 3-
16; 2017). Here, we present a short history of these
expeditions, concentrating on their scientific
achievements. In addition to expedition reports, a
large number of PhD theses, masters and honours
project reports and scientific papers have been
based on expedition work. Many biological
specimens have been deposited in museums,
including some new species. We provide case
histories of four expedition locations, to demonstrate
the variety of work done, and the value of returning
many times to the same place: Scotland, Trinidad and
Tobago, North Cyprus and Ecuador. A major problem
for expeditions is funding. For many years, the
Carnegie Trust for the Universities of Scotland ran a
funding stream that was crucial to the viability of
Scottish university expeditions, but this has sadly
now closed. For Glasgow University expeditions, the
Blodwen Lloyd Binns Bequest has provided a reliable
source since 1994, and we hope that it will continue
to do so

Scientific explanation and moral explanation
Moral philosophers are, among other things, in the business of constructing moral theories. And moral theories are, among other things, supposed to explain moral phenomena. Consequently, one’s views about the nature of moral explanation will influence the kinds of moral theories one is willing to countenance. Many moral philosophers are (explicitly or implicitly) committed to a deductive model of explanation. As I see it, this commitment lies at the heart of the current debate between moral particularists and moral generalists. In this paper I argue that we have good reasons to give up this commitment. In fact, I show that an examination of the literature on scientific explanation reveals that we are used to, and comfortable with, non-deductive explanations in almost all areas of inquiry. As a result, I argue that we have reason to believe that moral explanations need not be grounded in exceptionless moral principles
Effect of tomato by-products in the diet of Comisana sheep on composition and conjugated linoleic acid (CLA) content of milk fat
To evaluate the effect of supplementing the diet of Comisana sheep with by-products from industrial tomato manifacture on the composition and conjugated linoleic acid (CLA) content of milk fat, two groups of 50 ewes each were fed either total mixed ration standard (TMRS) or total mixed ration with added tomato by-products (TMRA). Milk fat composition was determinated by HRGC. The milk fat content for animals fed the TMRA diet increased by 6,41% aafter six weeks, compared with the animals fed the TMRS diet. The CLA content in the milk fat for the group of animal fed the TMRA diet was 19,8% higher than for those fed the TMRS diet. The fatty acid composition showed an increase in the amount of PUFA; the n-3:n-6 ratio increased by 13% in the milk from sheep fed with the TMRA diet
Lactoferrin and cancer disease prevention
Lactoferrin (LF) is an iron-binding glycoprotein that is composed of the transferrin family and is predominantly found in the products of the exocrine glands located in the gateways of the digestive, respiratory, and reproductive systems, suggesting a role in the non-specific defence against invading pathogens. Additionally, several physiological roles have been attributed to LF, namely regulation of iron homeostasis, host defence against infection and inflammation, regulation of cellular growth, and differentiation and protection against cancer development and metastasis. These findings have suggested LF's great potential therapeutic use in cancer disease prevention and/or treatment, namely as a chemopreventive agent. This review looks at the recent advances in understanding the mechanisms underlying the multifunctional roles of LF and future perspectives on its potential therapeutic applications.Fundação para a Ciência e a Tecnologia (FCT) - SFRH/BPD/26064/2005
Estructura de costos por procesos en la fijación de precios de venta para la producción de queso tipo paria en el Centro de Transformación familiar de derivados lácteos "Killalac" en el distrito de Ocongate, periodo 2015.
El presente trabajo de tiene como objetivo general: Establecer en qué medida la estructura de costos por procesos contribuye en la fijación de los precios de venta para la producción de queso tipo Paria del centro de transformación familiar de derivados lácteos “killalac” en el Distrito de Ocongate periodo 2015 y como objetivos específicos: Determinar los costos actuales de producción del queso tipo Paria del centro de transformación de derivados lácteos “killalac” en el Distrito de Ocongate periodo 2015. Determinar los costos de producción aplicando una estructura de costos por proceso de queso tipo Paria
del centro de transformación de derivados lácteos “killalac” en el Distrito de Ocongate periodo 2015. Establecer el proceso para la fijación de precios de venta del queso tipo Paria del centro de transformación familiar de derivados lácteos “killalac” en el Distrito de Ocongate periodo 2015.
La metodología que se empleó para llevar a cabo la investigación fue el enfoque cuantitativo con carácter descriptivo, con diseño no experimental, teniendo como población y muestra al mismo centro de transformación familiar de derivados lácteos “Killalac” en el distrito de Ocongate, las técnicas de recolección de datos fue la recopilación documental y los instrumentos de ficha de recolección de datos.
Los resultados del análisis, utilizando una estructura de costos por proceso, permitió determinar el costo que significa la producción de un kilo de queso de tipo Paria, el mismo que asciende a s/ 10.49, y el costo de comercialización es de s/ 0.51, lo que hace un total de s/. 11.00. Sobre este costo la ganancia es de s/. 2.50 aproximadamente que significa un 22.78% de utilidad por queso de tipo paria de un kilogramo de peso. Las conclusiones a las que se llegaron fueron las siguientes: El efecto de la aplicación de una estructura de costos por proceso en la determinación de precios de venta para la producción de queso tipo paria indiscutiblemente mejora puesto que podemos determinar el precio real de la producción del queso y el margen de utilidad que se estima para la venta al mercado (referencia tabla 38).
El centro de transformación de derivados lácteos “Killalac” determina sus costos de producción unitario actual de manera empírica, donde los únicos costos que se consideran son la materia prima (s/. 8.40), insumos (s/.0.30) y mano de obra (s/. 0.43) obteniendo un costo de s/. 9.13 y la ganancia se calcula al tanteo y por precio de mercado, creyendo que su margen de utilidad es de s/.4.37 para vender al mercado en s/. 13.50. Sin embargo eso no es la ganancia real por molde de queso (referencia tabla 5).
Mediante la determinación de una estructura de costos por proceso se sabe a ciencia cierta cuanto realmente es la utilidad generada por cada molde de queso, utilizando este sistema podemos apreciar los costos incurridos en la producción del queso. El costo de producción real de cada molde de queso tipo paria es de s/10.49, y el costo de comercialización asciende a s/ 0.51, lo que hace un total de s/.11.00. Sobre este costo la ganancia es de s/. 2.50 aproximadamente (referencia tabla 37).
La utilidad estimada por los propietarios de “Killalac” tiene un margen considerable de 22.78%. Eso se traduce en la producción de 50 quesos diarios y 1500 quesos por mes, lo que genera una utilidad mensual de s/.3750.00 (referencia tabla 38).The present research aims General: To establish the extent to which the process cost structure contributes to the determination of sales prices for the production of Paria cheese from the family processing center for dairy products "killalac" in the Ocongate District in 2015. And as objectives Specific Determine the current costs of production of Paria cheese from the "killalac" dairy processing center in the Ocongate District for 2015. Determine the costs of production by applying a cost structure per paria process cheese processing center Dairy "killalac" in Ocongate District 2015. Establish the process for the determination of sales prices of Paria cheese from the family transformation center for dairy products "killalac" in the Ocongate District for 2015 The methodology used to carry out the research was the quantitative approachwith descriptive character, with non-experimental design, having as population and
shows the same center of family transformation of dairy products "Killalac" in the district of Ocongate, the techniques of Data collection was the compilation of documents and data collection tools. The results of the analysis, using a cost-per-process structure, allowed us to determine the cost of producing a kilo of Paria cheese, which is equal to 10.49, and the cost of commercialization is s / 0.51.
Which makes a total of s /. 11.00. On this cost the profit is of s /. Approximately
2.50 which means a 22.78% profit per pariah type cheese of one kilogram of weight.
The conclusions reached were as follows: The effect of applying a cost-perprocess structurein the determination of sales prices for the production of pariahtype cheese undoubtedly improves since we can determine the real price of the Cheese and the profit margin estimated for sale to the market (reference tabl e 38).
The "Killalac" dairy processing center determines its current unit production costs in an empirical way, where the only costs considered are the raw material (s /.9.60), inputs (s / .0.30), and labor (S / .043), obtaining a cost of s /. 10.33 and the gain is calculated on a trial basis and by market price, believing that its profit margin is S / .4.17 to sell to the market in S /. 14.50. However that is not the actual gain per cheese mold (reference table 5).
By determining a structure of costs per process, it is known for sure how much is actually generated by each cheese mold, using this system we can appreciate the costs incurred in the production of cheese. The actual cost of production of each paria type cheese mold is s / 10.49, and the cost of commercialization amounts to s / 0.51, which makes a total of s /. 11.00. On this cost the profit is of s /. 2.50 approximately (reference table 37).
The profit estimated by the owners of "Killalac" has a considerable margin of 22.78%. This results in the production of 50 daily cheeses and 1500 cheeses per month, which generates a monthly profit of s / .3750.00 (reference table 38).Tesi
