From nationhood to non·nationhood: migratory sujectivities in the amazon bioregion

Como la construcción de la identidad basada en la nacionalidad va perdiendo importancia, es indispensable analizar otras maneras de formular la identidad que toman su lugar. En el caso de la región Amazónica, el concepto de una bioregión, que se define no por alguna especie de patriotismo o Fronteras políticas sino por un ecosistema particular y la interacción de individuales dentro del ecosistema, mejor explica cómo los residentes amazónicos Forman una comunidad e identidad. La bioregión, porque se trata de Fronteras geográficas o naturales, entiende mejor la cosmología amazónica, la cual se basa en el ecosistema en que residen los humanos y no humano.As identity based nationality is losing its importance, it is increasingly important to anaIyze other ways in which identity formation takes its place. In the case of the Amazonian region, the concept of a bioregion, defined not by any patriotism or poltical boundaries, but by a particular ecosystem and the interaction of individuals in that ecosystem, better explains how those who reside in the Amazon form a community and identily. Bioregions, because they dea l with geographic or natural boundaries, encompasses Amazonian cosmology, which is based on the ecosystem which humans and non-humans inhabit together

Consensus making in requirements negotiation : the communication perspective

When developing an Information System (IS), organizational goals of various stakeholders are commonly in direct conflict. Furthermore, individuals often rank their private objectives well over their management\u27s directions. Recognising and reconciling all these diverse goals, and reaching agreement among the stakeholders, are prerequisite to establishing project cooperation and collaboration. This paper focuses, in particular, on the negotiation and consensus making during requirements elicitation - the earliest stages of the IS development process. As requirements elicitation involves rich communication between project stakeholders, we therefore explore negotiation and consensus making from the communication perspective. The resulting model assists our understanding of the communication factors that influence the consensus process during requirements negotiation.<br /

The Intersection of Radar and Communications: A Study on Spectrum Management for Addressing RF Interference

The radio frequency (RF) spectrum is a fruitful yet competitive frontier that enables technologies like 5G, Wi-Fi, Bluetooth, GPS, long-range telescopes, microwave ovens, radar, and more. With finite supply and increasing demand, the RF spectrum is highly contested for both government and private use. Industry innovators need an increasing stake in the spectrum to keep up with modern data consumption needs, yet governments around the world require the same spectrum for important issues like national defense. This duality in demand often results in highly congested bands of frequency that host both stakeholders in dense configuration, increasing interference and difficulties in managing the spectrum. Interference of radar signals by communication waveforms, like orthogonal frequency division multiplexing (OFDM), is on the rise and can greatly impact system performance. This thesis introduces a novel interference mitigation algorithm that leverages the known structure of OFDM waveforms to estimate and subtract interference from a pulse-Doppler radar system. The proposed technique can significantly improve radar performance in the face of OFDM interference and quantify interference metrics to inform new regulations pertaining to spectrum management

Urban understandings: exploring potential coercion in Lincoln Park’s gentrification process

While much research has been carried out on the topic of gentrification over the past several decades, little to no economic research has been conducted on the potential presence of coercion within the process. In this paper, we define coercion as any attempts by third parties, whether government or private entities, to artificially accelerate the natural housing cycle. In studying this, we examine Lincoln Park as a case study, a Chattanooga neighborhood that was once a bastion of culture and security for the Southern African American community, by employing a two-pronged approach. On the qualitative front, we interview community and city leaders, as well as employ investigative journalism in researching the existing literature, including books and newspapers, on the history of Lincoln Park. Quantitatively, we build and conduct a survey among the residents of the neighborhood, allowing us to run empirical analyses upon the data. Combing the two approaches, we construct a holistic study of the potential presence of coercion within Lincoln Park’s housing and development process. In the end, while we find examples of coercive efforts on the part of the city of Chattanooga as it relates to Lincoln Park as recently as the past decade, these efforts do not seem aimed at accelerating the natural housing cycle, meaning they do not meet our criteria of coercion. Thus, as we have defined it, we do not find coercion within the context of Lincoln Park’s gentrification process
