PREVIEW; McCoy v. Salish Kootenai College, Inc.: \u3cem\u3eHow Far Does Sovereign Immunity Extend?\u3c/em\u3e

This case presents the issue of whether a tribal college, incorporated under the laws of the Confederated Salish and Kootenai Tribes and, subsequently, the State of Montana, may be considered an arm of the Tribe, thus benefitting from tribal sovereign immunity. The resolution of this issue will influence tribal jurisdictional questions throughout the state and the country. The Appellant, Stephen McCoy, asserts that the federal courts have federal question jurisdiction over his Title VII claims against Appellee, Salish Kootenai College, Inc. because it is not an arm of the Tribe and therefore is not immune from Title VII claims

The triple cross-platform sequence and the social audience in COPE. The distributed narration of contents in the antenna, the web, social networks and alerts to mobile phone during the Day of the Radio in ‘Herrera in COPE’

Las redes sociales forman parte ya de nuestro ecosistema informativo. Representan el nuevo motor de comunicación, de relación entre personas que no se conocen de nada, de convocatoria ante hechos programados o imprevistos. De puente para los medios. Ha cambiado el concepto de comunicación por el de conexión y en este contexto, la radio digital debe esforzarse a diario por ofrecer nuevos modelos de narración y por renovar lenguajes. Debe volcarse en la producción transmedia como modo de pensar la creación de contenidos en sus coberturas de acuerdo con los nuevos hábitos de consumo e interacción con las audiencias. Debe pasar del interés público al interés del público. The new mobile devices have changed the way they access content, have created new consumption habits and have made it possible to be connected at any time. In this context, digital radio should strive daily to offer new communication models. The radio must be able to make the most of the triple multiplatform sequence, object of study of the case of ‘Herrera en COPE’. In that sequence, the antenna, the web, the networks and the alerts to mobile phone have their rhythm and their distribution time and each content their format. This research sets its objective through qualitative and quantitative techniques to check whether the existence of a strategy that goes through an integrated wording, improves the creation of content during a planned event such as Radio Day, its subsequent distribution on different platforms and interaction with the audiences. One of the main conclusions reflects how the cross-promotion of the COPE brand through the antenna, the web, the app and the networks loyalized the public. The number of concurrent users increased by 8% and the number of new ones by 65%

Arithmetic word problem solving: evidence for a magnitude-based mental representation

[EN] Previous findings have suggested that number processing involves a mental representation of numerical magnitude. Other research has shown that sensory experiences are part and parcel of the mental representation (or “simulation”) that individuals construct during reading.We aimed at exploring whether arithmetic word-problem solving entails the construction of a mental simulation based on a representation of numerical magnitude. Participants were required to solve word problems and to perform an intermediate figure discrimination task that matched or mismatched, in terms of magnitude comparison, the mental representations that individuals constructed during problem solving. Our results showed that participants were faster in the discrimination task and performed better in the solving task hen the figures matched the mental representations. These findings provide evidence that an analog magnitude-based mental representation is routinely activated during word-problem solving, and they add to a growing body of literature that emphasizes the experiential view of language comprehension

Influence of situational and conceptual rewording on word problem solving

Se analiza la doble naturaleza semántica y textual de la tarea de resolver un problema matemático en el aula.Background: Studies on rewording word problems can be grouped into two main groups: situational rewording, in which the situation denoted by the text is described more richly, and conceptual rewording, in which the underlying semantic relations are highlighted. Aims: Our aims are to define and distinguish these two kinds of rewording and to test empirically their relative effectiveness in two different studies. Sample: In the first study, 79 third graders, 64 fourth graders and 65 fifth graders took part; the sample for Study 2 was similar. Method: In Study 1, children were asked to solve both easy and difficult two-step change problems in three different versions: standard, situational and conceptual rewording. In Study 2, three different versions of the situational version were compared: one with only temporal elaborations, one with only causal elaborations and a "complete" version combining both elaborations. Results: In Study 1, conceptually reworded problems elicited the best results, especially among younger children and for difficult two-step problems. Neither in Study 1 nor in Study 2 did the situationally reworded problems yield better performance than standard items. Conclusion: Only conceptual rewording has proved to be useful for improving children's performance, especially among younger children and for difficult problems. The lack of impact of situational rewording cannot be explained in terms of the length of the resulting text

“En la corriente viajan…”

In Colombia, the waters of rivers like the Magdalena have become stages for the exposure of terror and loss. However, in this essay I want to propose an alternative approach to water and its relation to violence. Based on the process of fermentation, both as metaphor and material reality, I suggest the possibility of imagining a form of sensual memory brought about by the interaction with waters that contain residues of terror. For this I rely on a series of ethnographic fragments and photographs of daily life in the town of Nueva Venecia, where water impregnated by the residues of a massacre trickles through spaces, instances and stages of the everyday life. These moments open up the possibilities of understanding this relationship with water and its residues as part of a narrative of memory rather than oblivion.En Colombia las aguas de ríos como el Magdalena han sido escenario de la expresión del terror y el olvido. Sin embargo, en este ensayo quiero proponer una mirada alternativa del agua y su relación con la violencia. A partir del proceso de la fermentación como metáfora y realidad material, sugiero la posibilidad de imaginar una forma de memoria sensual que se genera por medio de la interacción con agua saturada con historias de terror. Para esto utilizo una serie de fragmentos etnográficos y fotografías de la vida diaria en el pueblo de Nueva Venecia en la Ciénaga Grande, donde el agua que fue impregnada por los residuos de una masacre se filtra en espacios, instantes y escenarios del diario vivir. Estos momentos plantean la posibilidad de leer esta relación con el agua y sus residuos como parte de una narrativa de memoria en vez de olvido

Reduction of arsenic content in a complex galena concentrate by Acidithiobacillus ferrooxidans

BACKGROUND: Bioleaching is a process that has been used in the past in mineral pretreatment of refractory sulfides, mainly in the gold, copper and uranium benefit. This technology has been proved to be cheaper, more efficient and environmentally friendly than roasting and high pressure moisture heating processes. So far the most studied microorganism in bioleaching is Acidithiobacillus ferrooxidans. There are a few studies about the benefit of metals of low value through bioleaching. From all of these, there are almost no studies dealing with complex minerals containing arsenopyrite (FeAsS). Reduction and/or elimination of arsenic in these ores increase their value and allows the exploitation of a vast variety of minerals that today are being underexploited. RESULTS: Arsenopyrite was totally oxidized. The sum of arsenic remaining in solution and removed by sampling represents from 22 to 33% in weight (yield) of the original content in the mineral. The rest of the biooxidized arsenic form amorphous compounds that precipitate. Galena (PbS) was totally oxidized too, anglesite (PbSO(4)) formed is virtually insoluble and remains in the solids. The influence of seven factors in a batch process was studied. The maximum rate of arsenic dissolution in the concentrate was found using the following levels of factors: small surface area of particle exposure, low pulp density, injecting air and adding 9 K medium to the system. It was also found that ferric chloride and carbon dioxide decreased the arsenic dissolution rate. Bioleaching kinetic data of arsenic solubilization were used to estimate the dilution rate for a continuous culture. Calculated dilution rates were relatively small (0.088–0.103 day(-1)). CONCLUSION: Proper conditions of solubilization of arsenic during bioleaching are key features to improve the percentage (22 to 33% in weight) of arsenic removal. Further studies are needed to determine other factors that influence specifically the solubilization of arsenic in the bioleaching system such as: pH, dissolved oxygen concentration, redox potentials, nature of concentrate and temperature among others. At. ferrooxidans was able to completely oxidize the minerals present during the arsenic bioleaching. Other elements present originally in the concentrate such as Zn, Sb, and Cu were also solubilized. The process of bioleaching is expected to be influenced by mechanisms that still need to be established due to the diversity of the minerals involved and by the presence of traces of metals in the concentrate. The increase in pulp density generates a decrease in the dissolved arsenic concentration. This decrease is greater in runs where air was not injected to the system. The maximum rate of arsenic dissolution in the concentrate was found using; small surface area of particle exposure, low pulp density, injecting air and adding 9 K medium to the system. The effect of addition of ferric chloride during the arsenic bioleaching resulted in a decrease of the solubilized arsenic in the system. The presence of CO(2 )is associated to the decrease in arsenic dissolution
