A Comparison Of Path Loss Variations In Soil Using Planar And Dipole Antennas, Abdul Salam

Computer Information Technology Faculty Publications

In this paper, an empirical investigation of propagation path loss variations with frequency in sandy and silty clay loam soils has been done using planar and dipole antennas. The path loss experiments are conducted using vector network analyzer (VNA) in sandy soil testbed, and greenhouse outdoor silty clay loam testbed for different operation frequencies and communication distances. The results show that the planar antenna can be used for subsurface communications in a wide range of operation frequencies. The comparison paves the way for development of sensor-guided irrigation system in the field of digital agriculture.

Underground Soil Sensing Using Subsurface Radio Wave Propagation, Abdul Salam, Akhlaque Ahmad

Computer Information Technology Faculty Publications

Continuous sensing of soil moisture is essential for smart agriculture variable rate irrigation (VRI), real-time agricultural decision making, and water conservation. Therefore, development of simple techniques to measure the in-situ properties of soil is of vital importance. Moreover, permittivity estimation has applications in electromagnetic (EM) wave propagation analysis in the soil medium, depth analysis, subsurface imaging, and UG localization. Different methods for soil permittivity and moisture estimation are time-domain reflectometry (TDR), ground-penetrating radar (GPR) measurements, and remote sensing. One major bottleneck in the current laboratory-based permittivity estimation techniques is off-line measurement of the collected soil samples. At that, the remote …

Transforming Trauma: Resilience And Healing Through Our Connections With Animals, Philip Tedeschi, Molly Anne Jenkins

Purdue University Press Books

Have you ever looked deep into the eyes of an animal and felt entirely known? Often, the connections we share with non-human animals represent our safest and most reliable relationships, offering unique and profound opportunities for healing in periods of hardship. This book focuses on research developments, models, and practical applications of human-animal connection and animal-assisted intervention for diverse populations who have experienced trauma. Physiological and psychological trauma are explored across three broad and interconnected domains: 1) child maltreatment and family violence; 2) acute and post-traumatic stress, including military service, war, and developmental trauma; and 3) times of crisis, such …

Mapping Industry Standards And Integration Opportunities In Business Management Curricula, Margaret Phillips, Heather Howard, Alyson Vaaler, David E. Hubbard

Libraries Faculty and Staff Scholarship and Research

Industry standards have a significant impact on business as a means to eliminate waste, reduce costs, market products (e.g., for quality, safety, interoperability) and lessen liability (Thompson, 2011). Consequently, an understanding and the ability to use standards, agreed upon practices among interested or vested parties, is a critical workplace competency for those engaged in business and industry. To have a workforce competent in the use of standards, higher education curricula must be developed to integrate standards education at appropriate points within the curriculum. Despite the importance of standards, they are not universally integrated into the college and university curricula.

A Systematic Review Of Studies On Educational Robotics, Saira Anwar, Nicholas Alexander Bascou, Muhsin Menekse, Asefeh Kardgar

Journal of Pre-College Engineering Education Research (J-PEER)

There has been a steady increase in the number of studies investigating educational robotics and its impact on academic and social skills of young learners. Educational robots are used both in and out of school environments to enhance K–12 students’ interest, engagement, and academic achievement in various fields of STEM education. Some prior studies show evidence for the general benefits of educational robotics as being effective in providing impactful learning experiences. However, there appears to be a need to determine the specific benefits which have been achieved through robotics implementation in K–12 formal and informal learning settings. In this study, …

Urban Landscape In Mcewan's Narrative Representation Of Berlin, Barbara J. Puschmann-Nalenz

CLCWeb: Comparative Literature and Culture

In her article "Urban Landscape in McEwan's Narrative Representation of Berlin," Barbara J. Puschmann-Nalenz discusses the image of Berlin created in Ian McEwanﹸs novel The Innocent (1990) and the chapter titled "Berlin" in Black Dogs (1992). It starts from the hypothetical statement that while British literary fiction set in Berlin is rare after 1970 the genres of spy and detective novel, where crime and violence take center stage, shape the image of the city in highbrow narratives as well. The perspectivization of the cityscape, including its monuments, through the protagonists fundamentally influences its image. In The Innocent the limited view …

The Disenchantment Of History And The Tragic Consciousness Of Chinese Postmodernity, Alberto Castelli

CLCWeb: Comparative Literature and Culture

Magic Realism brings fantastic events into the frame of the narration. Yet it cannot quite be defined. At the very start of the process of definition, there is a question: Magic Realism is a mode of narration, or rather a post-colonial movement rising sociological issues alternative to the logic of power? The paper parallels and juxtaposes Latin American Magic Realism and the literary experience of Chinese literary Avant-garde in the 80s, similar apocalyptic thematic, but different narrative structures. Relating to the fictional universe of Can Xue and Yu Hua, the aim is to illuminate an exclusive mode to narrate history: …

Okonkwo’S Reincarnation: A Comparison Of Achebe’S Things Fall Apart And No Longer At Ease, Mary J. N. Okolie, Ginikachi C. Uzoma

CLCWeb: Comparative Literature and Culture

Abstract: The reincarnation myth is a global concept, founded basically in religion and tradition. It was especially vibrant in the ancient times in places like Egypt, Greece, and in continents like Asia and Africa, which possess varying understandings of the myth. In Igbo tradition, for example, it is believed that reincarnation occurs within a family. And that some of the marks of reincarnation are usually the possession of the birthmark or certain other physical features and the exhibition of character and behavioral traits of a deceased person by a living member of his/her immediate or extended family. Thus, reincarnation entails …

Translating Policy To Practice: Theory-Based Formative Research To Improve Ec Otc Access And Messaging In Italy, Kathryn L. Jamieson, Emily Ball, Scotlyn Sunkel

Purdue Undergraduate Research Conference

Background: Italy's 2015 emergency contraception (EC) policy has increased access and reduced some barriers for women to obtain EC. EC is now available over-the-counter for individuals 18 years and older; however, women living in Italy continue to face knowledge and access barriers. Conscientious objection, where providers and pharmacists refuse to prescribe or dispense EC due to personal beliefs, further complicates access and dissemination. Objective: The purpose of the current paper is to understand EC knowledge, attitudes, and behaviors among women living in Italy. Additionally, a secondary purpose is to explore the impact of the 2015 EC policy. Methods: Thirty in-person …

Indoor Positioning System, Ximeng Zhang, Qianli Ma

Purdue Undergraduate Research Conference

The purpose of our project is to develop a complementary system to the current GPS with a focus on indoor localization and navigation. The current need for localization extends beyond what GPS can provide in today’s state of technology. Radio signals used in the global system are vast but weak, unable to penetrate obstacles and buildings in high density, populous areas of the world. Our system is designed to solve this problem by implementing an Indoor Localization System using a stronger ultra-wideband signal in the frequency spectrum. At a high level, the system is modeled after the architecture of the …

Perceptions Of Ally Confrontations, Celine Jusuf

Purdue Undergraduate Research Conference

Research related to interpersonal confrontations, where one person points out a way in which another person had engaged in stereotypical or prejudicial bias, has provided a wealth of knowledge about factors that influence the extent to which confrontations reduce bias (e.g., Czopp, Monteith, & Mark, 2006; Chaney & Sanchez, 2017; Mallet & Wagner, 2011; Parker, Monteith, Moss-Racusin, & Van Camp, 2018). However, how do minority-group members perceive confrontations on behalf of their social/ethnic group, and does group membership of the confronter matter? The present experiment investigates how Asian women perceive confrontations of prejudice against their group when performed by an …

Dewey’S Ideas In Action! Continuing Professional Development In An International Community Of Practice, Sabrina R. Goldberg

Education and Culture

Drawing on Dewey’s concepts and thinking, a middle school mathematics teacher at The School at Columbia University describes her teaching practice and role as a field-based teacher-educator and professional development leader during EdTech Summit Africa. Through a first-person account of her experiences in Cape Town, Johannesburg, and Pretoria, South Africa, the author reflects on how professional development with technology was embraced and illuminates why the development of an international community of practice with primary, secondary, and tertiary teachers is evolving. The article is divided into four sections.

Bordentown: Where Dewey’S “Learning To Earn” Met Du Boisian Educational Priorities, Connie Goddard

Education and Culture

John Dewey and W.E.B. Du Bois were prominent critics of how vocational education programs were often used to restrict rather than enhance student aspirations. An overview of the Bordentown Manual Training and Industrial School for Colored Youth (1886–1955) suggests that it met requirements both men articulated for the right kind of vocational education; however, the school’s legacy has been largely ignored by historians. Further, Dewey and Du Bois, who knew of but had little interaction with each other, may never have discussed their shared interest in vocational education or their awareness of the school’s mission and accomplishments.

Dewey’S Political Technology From An Anthropological Perspective, Shane J. Ralston

Education and Culture

This article explores the possibility that John Dewey’s silence about which democratic means are needed to achieve democratic ends, while confusing, makes greater sense if we appreciate the notion of political technology from an anthropological perspective. Michael Eldridge relates the exchange between John Herman Randall, Jr. and Dewey in which Dewey concedes “that I have done little or nothing in this direction [of outlining what constitutes adequate political technology, but that] does not detract from my recognition that in the concrete the invention of such a technology is the heart of the problem of intelligent action in political matters.” Dewey’s …

Cultivating Democratic Hope In Dark Times: Strategies For Action, Kathy Hytten

Education and Culture

In this essay, I reflect on the need for an activist notion of hope as an antidote to the social, political, and educational challenges we face in our current times. I first discuss some of these challenges as well as emergent signs of hope based upon different ways of telling the stories of our present. I then define hope as a way of being and intervening in the world, as opposed to a personal character trait or optimistic demeanor, and discuss some enemies of hope. In the heart of the essay, I discuss four important habits of hope that can …

"Il Y A De La Plèbe": Figurations Of The Minor Between Complicity And Dissent, Maria Muhle

CLCWeb: Comparative Literature and Culture

In this article I discuss the logic of “complicity” and “dissent” that, under current forms of ultra-neoliberal capitalism, is no longer (if it has ever been) one of opposition but rather corresponds to a logic of unrealized potentials, or “as ifs” that “manage” dissent and complicity in conjunction, and erase the dividing line between them, or their value as separate concepts. I examine the genealogy of this opposition and its dilution as a symptom of our contemporary political reality. Michel Foucault presented a paradigmatic view of this genealogy in his analysis of power and the taxonomic separation of three regimes …

Political Violence And Race: A Critique Of Hannah Arendt, Chad Kautzer

CLCWeb: Comparative Literature and Culture

Hannah Arendt’s On Violence (1970) is a seminal work in the study of political violence. It famously draws a distinction between power and violence and argues that the latter must be excluded from the political sphere. Although this may make Arendt’s text an appealing resource for critiques of rising political violence today, I argue that we should resist this temptation. In this article, I identify how the divisions and exclusions within her theory enable her to explicitly disavow violence on one level, while implicitly relying on a constitutive and racialized form of violence on another. In particular, Arendt leaves legal …

The Ambivalence Of Black Rage, Vincent Lloyd

CLCWeb: Comparative Literature and Culture

Activists associated with the Black Lives Matter movement embrace anger. Owning their rage sets these activists in opposition to an older generation of black leaders, invested in respectability, who narrate anger as an emotion to be overcome. Younger activists worry about complicity with the status quo – with white supremacy – of these older activists, yet embracing anger is no surefire way of avoiding complicity with the status quo. This essay investigates the ambivalence of black anger, drawing on philosophy and feminist theory while also locating the current eruption of black anger in an ambivalent history of black political affect. …

Complicity, Dissent, And The Palestinian Intellectual, Sa'ed Atshan

CLCWeb: Comparative Literature and Culture

In this article, I draw on the major works of two Palestinian intellectuals—Edward Said and Hanan Ashrawi—and I compare the experiences of Palestinian intellectuals living in the United States with those living under Israeli military occupation in the West Bank. The writings of these two exemplary figures shape the conceptual underpinnings of my exploration of the way Palestinian academics navigate questions of complicity with the different hegemonic political systems that govern their lives. I argue that Said and Ashrawi model a steadfast refusal to be complicit in the state-led repression around them at the same time as they engage in …

Family Affairs: Complicity, Betrayal, And The Family In Hisham Matar's In The Country Of Men And Nadine Gordimer's My Son's Story, Lital Levy

CLCWeb: Comparative Literature and Culture

This essay undertakes a comparative reading of the dynamics of complicity and resistance in two contemporary Anglophone novels, Nadine Gordimer’s My Son’s Story (1990) and Hisham Matar’s In the Country of Men (2006). My analysis pursues three main lines of inquiry: the ostensible public/ private and political/ personal divides; loyalty and betrayal in the family; and the ambiguous status of the child as a witness and a political subject. I argue that in their respective portrayals of the protagonists’ struggles against South African apartheid and authoritarian rule in Libya, both authors use the device of the child narrator to expose …

Facing The Ruler, Facing The Village: On The Roads To Complicity Following Mengzi And Benda, Zvi Ben-Dor Benite

CLCWeb: Comparative Literature and Culture

In his article, “Facing the Ruler, Facing the Village,” Zvi Ben-Dor Benite seeks to broaden the boundaries of the discussion about complicity by taking it away from late 20th-century and contemporary debates about it. At the same time, he wishes to highlight the many faces that the problem of complicity could have in different historical moments. Following Czesław Miłosz, this article understands that there are many roads to complicity that have been articulated in different ways across time and space. This article is, therefore, an integrated meditation on complicity bringing together two radically distant approaches to the question. Reading the …

Remnants Of Dissent, Thomas Docherty

CLCWeb: Comparative Literature and Culture

In his article, “Remnants of Dissent,” Thomas Docherty explores the relation of dissent to guilty complicity in post-war Europe. The article opens with a consideration of the position of Karl Jaspers in 1945 and examines how Jaspers worked through the various modes of guilt that flowed from diverse modes of living under Nazism. Of particular interest is the status of silence in the face of tyrannical Nazi oppression and murders. The essay explores how the workings of language, and its manipulations by the Nazis, helps to normalize such tyranny and to make resistance to it both dangerous and difficult. The …
