COMM 260-01: Public Speaking

After more than two thousand years, public speaking remains a central topic in a myriad of cultures. In order to understand the process of public speaking as well as to improve one’s public speaking skills in the 21st century, two steps prove fundamental. Firstly, behind every instance of public speaking, a complex intersection of factors takes place. Therefore, it becomes essential to critically examine these factors as well as to analyze the fluid relationship between speaker, audience, and context (at the micro and macro levels). Moreover, it is necessary to examine the role of public speaking in a democracy. Secondly, the theoretical dimension aims to enhance the personal application of critical public speaking skills in synchronous and asynchronous interactions, as speakers, listeners, and members of society at large. For that purpose, COMM 260 emphasizes the theory of speech composition, presentation, and evaluation and its relationship to public discourse, civic engagement, and the ethics of persuasion. This course provides a critical application of theory through the online presentation of several formal and impromptu speeches. Requirements include frequent online speaking assignments and related practices, including written analyses of speeches. Thus, active online participation and critical engagement prove essential in this course. This course is fully online; students will not be required to be physically present for any component of the class.https://scholarworks.umass.edu/communication_ed_materials/1000/thumbnail.jp

Fuzzy closure systems: Motivation, definition and properties

The aim of this paper is to extend closure systems from being crisp sets with certain fuzzy properties to proper fuzzy sets. The presentation of the paper shows a thorough discussion on the different alternatives that could be taken to define the desired fuzzy closure systems. These plausible alternatives are discarded if they are proven impossible to be in a bijective correspondence with closure operators. Finally, a definition of fuzzy closure system is established and a one-to-one relation with closure operators is proved.The aim of this paper is to extend closure systems from being crisp sets with certain fuzzy properties to proper fuzzy sets.

The role of the cationic and helper lipids on niosomes for gene delivery applications: transfection of retina and brain as a main goal.

145 p.Currently, gene delivery has become a tangible option for the treatment of several diseases. However, there are few available options in the market, where viral vectors are the preferred option due to their high transduction efficiency. Despite the advantages that viral vectors offer, there are still many concerns about their safety. To overcome this issue, non-viral vectors have rouse interesting expectations, specifically on particles based on cationic lipids, where niosomes are a promising approach due to recent findings. Unfortunately, more research is needed bejore niosomes, as gene delivery vectors, can emulate transfection efficiencies obtained with viral vectors and be launched into the market. In the present study, we have prepared and characterized in vitro niosome formulations based on different cationic lipids for their in vivo application in retina and brain

THE COYOLXAUHQUI PROCESS OF A SCHOLAR UNBECOMING AN ENEMY OF YOUTH: A PERFORMATIVE, EMBODIED, SELF-DECOLONIZING STORY OF TRANSFORMATION AND HOPE

Scholarly work may be used to foster colonizing processes upon people of color whether scholars are aware of it or not. That is the case of the study of youth bullying in the United States, an old issue that, however, became a central social concern in the United States in the late 1990s. Building upon scholars’ framing of youth bullying, a combination of moral panics on youth unfolded, fostering a law-and-order regime in schools that expanded the application of zero-tolerance policies. These policies fed the school-to-prison pipeline that funnels youth into the criminal justice system, a form of internal colonization that polices, incarcerates, and exploits youth of color in the United States. As a researcher on youth bullying, I was oblivious to this harmful outcome. I was becoming an enemy of youth of color and I committed to unbecoming one, using this dissertation for that purpose. First, by tracing the genealogy of the study of youth bullying and how academic premises became Gramscian common sense. Second, by reflecting upon and redressing my complicity with (neo)colonialism. I use performance x autoethnography and Anzaldúa’s Coyolxauhqui imperative as methods to unfold a self decolonizing process as a Canary Islander and queer diasporic nepantlera who is a colonize(d)(r) scholar. The new conocimiento that I obtain in this process allows me to look at the study of youth bullying with a different gaze. As a result, I offer an alternative onto-epistemological and methodological approach to the study of youth bullying in the United States. I advocate for a collective decolonizing reframing of youth bullying based upon centering youth’s agency, challenging adult researchers’ standpoint, suggesting other onto-epistemological and conceptual approaches, as well as promoting other values and tactics in the study of youth peer abuse and violence. This dissertation, in sum, is an onto-epistemo-methodological embodied reflection that offers a methodological contribution on how to study youth bullying in less colonizing ways. Likewise, it contributes to methodological conversations on how to use performance autoethnography to self-decolonize as well as how to decolonize performance autoethnography. Moreover, this text contributes to better understanding diasporic experience and expands the literature on the Canarian diaspora. Fundamentally, this dissertation contributes to decolonizing academia

Causas y Consecuencias del Consumo Excesivo de la Comida Chatarra

La alimentación es el derecho humano fundamental más importante y esencial para el desarrollo social y económico de una persona. Una buena alimentación y nutrición contribuye en la mejora, la eficiencia y los resultados de acciones del desarrollo personal, mayor capacidad de aprendizaje, menores gastos para el cuidado de la salud, mayor productividad, entre otros. La alimentación, como base para el desarrollo humano, está relacionado con la educación, la salud, la demografía, la agricultura, la pobreza y el género. La comida rápida es, hoy en día, una comida muy consumida gracias a sus intensos sabores, su palatabilidad, y su facilidad para adquirirla, si bien este tipo de alimento conlleva una serie de características nutricionales, que hacen que no sea aconsejable su consumo habitual. Entre estas características destaca su abundancia en grasas saturadas y colesterol Nutricionalmente, las comidas chatarra coinciden en un aporte de alta densidad energética y calórica y un alto contenido en grasas (saturadas) e hidratos de carbono. Además, contienen bastante colesterol y, aunque su contenido mineral es deficiente, en el caso del sodio sucede todo lo contrario, siendo ricos en este mineral. Son también deficientes en fibra y vitaminas, aunque podemos resaltar como positivo que aportan proteínas de alto valor biológicos si se consumen moderadamente. La comida chatarra, también conocida como comida basura, contiene por lo general altos niveles de grasas, sal, azúcares y otros componentes que estimulan el apetito y la sed, lo que tiene un gran interés comercial para los establecimientos que proporcionan ese tipo de comida. La comida chatarra se relaciona con la obesidad, con las enfermedades cardíacas, la diabetes, las caries, la celulitis y otros males. La comida chatarra por lo general tiene buen sabor, pero no es nutritiva, es barata y muy accesible, es fácil de preparar, es cómoda de ingerir en la calle o lugares públicos, y su publicidad es muy agresiva. Esta comida es la que se vende más en los centros educativos, restaurantes o tiendas que ofrecen una rápida preparación y servicio. Son alimentos procesados de tal manera que son rápidamente servidos. El presente documento, tiene la finalidad de llamar la atención, informar y sensibilizar al público sobre los peligros de la comida chatarra en contraposición con los beneficios de la alimentación –nutrición saludable. Esperamos que la información que brindamos sirva para incidir, principalmente, en la población y así tomar en cuenta los alimentos sanos y nutritivos. También se busca que los consumidores reflexionen que el consumo responsable de alimentos tiene múltiples beneficios frente al consumo de comida chatarra. Una buena nutrición contribuye al desarrollo humano más saludable para vivir bien

Yield Components in Annual Ryegrass and Oats Grown in Association and Monoculture

Earliness of oats and higher growth rate of annual ryegrass later in the season explain the higher forage yield of annual ryegrass+oats association over monocultures (Améndola & Morales, 1997). However, changes in yield components of the species grown in association compared to monoculture have not been explored. This study aimed to determine leaf, stem and dead matter yield in annual ryegrass and oats when grown in association and monoculture at different nitrogen (N) levels

Lexicon-based sentiment analysis in texts using Formal Concept Analysis

In this paper, we present a novel approach for sentiment analysis that uses Formal Concept Analysis (FCA) to create dictionaries for classification. Unlike other methods that rely on pre-defined lexicons, our approach allows for the creation of customised dictionaries that are tailored to the specific data and tasks. By using a dataset of tweets categorised into positive and negative polarity, we show that our approach achieves a better performance than other standard dictionariesThis research is partially supported by the State Agency of Research (AEI), the Spanish Ministry of Science, Innovation, and Universities (MCIU), the European Social Fund (FEDER), the Junta de Andalucía (JA), and the Universidad de Málaga (UMA) through the FPU19/01467 (MCIU) internship and the research projects with reference PGC2018-095869-B-I00, TIN2017-89023-P, PID2021-127870OB-I00 (MCIU/AEI/FEDER, UE) and UMA18-FEDERJA-001 (JA/ UMA/ FEDER, UE).
