Suncircles: A Prose/Poem 12/18/2014, Charles Kay Smith Dec 2014

Suncircles: A Prose/Poem 12/18/2014, Charles Kay Smith

Charles Kay Smith

A current project is writing a book of poetry. The different kind of poetry I’m trying to write melds science, humanities, and aesthetic aims of clarity and a polished plain style with social consciousness. I’m uploading one of the poems in the collection as an example of the kind of poetry I’m trying to compose.


Innovative Representations Of Light, Behaving As Both Particles And Waves, Among The Paintings Of Monet And Renoir, Charles Smith Nov 2014

Innovative Representations Of Light, Behaving As Both Particles And Waves, Among The Paintings Of Monet And Renoir, Charles Smith

Charles Kay Smith

Monet and Renoir, friends collaborating in open air about 1865, discovered that sunlight filtering through a canopy of tree leaves does not produce the splotches and dapples that studio artists conventionally represented at the time but circles of light. Sometimes the circles of light punctuating the shade are clear, separate and crisp, as though light is being propagated as particles, but if the pin-hole gaps between leaves are very close together, they will project compound or superimposed circles that look like the waves that Thomas Young saw in his double slit experiment in 1803-4. Newton’s Opticks published in 1704 had …


Driver Dynamics And The Longitudinal Control Model, Gabriel Leiner Feb 2014

Driver Dynamics And The Longitudinal Control Model, Gabriel Leiner

Gabriel Leiner

Driver psychology is one of the most difficult phenomena to model in the realm of traffic flow theory because mathematics often cannot capture the human factors involved with driving a car. Over the past several decades, many models have attempted to model driver aggressiveness with varied results. The recently proposed Longitudinal Control Model (LCM) makes such an attempt, and this paper offers evidence of the LCM's usefulness in modeling road dynamics by analyzing deceleration rates that are commonly associated with various levels of aggression displayed by drivers. The paper is roughly divided into three sections, one outlining the LCM's ability …


The Politics Media Equation:Exposing Two Faces Of Old Nexus Through Study Of General Elections,Wikileaks And Radia Tapes, Ratnesh Dwivedi Mr Oct 2013

The Politics Media Equation:Exposing Two Faces Of Old Nexus Through Study Of General Elections,Wikileaks And Radia Tapes, Ratnesh Dwivedi Mr

Ratnesh Dwivedi

The important identity of a responsible media is playing an unbiased role in reporting a matter without giving unnecessary hype to attract the attention of the gullible public with the object of making money and money only.After reporting properly the media can educate the public to form their own opinion in the matters of public interest. Throughout the centuries, the world has never existed without information and communication, hence the inexhaustible essence of mass media. The government has the power to either make or reject whatever that will exist within its environment. It also determines how free the mass media …


An Ethnographic Study: Becoming A Physics Expert In A Biophysics Research Group, Idaykis Rodriguez Jul 2013

An Ethnographic Study: Becoming A Physics Expert In A Biophysics Research Group, Idaykis Rodriguez

Idaykis Rodriguez

Expertise in physics has been traditionally studied in cognitive science, where physics expertise is understood through the difference between novice and expert problem solving skills. The cognitive perspective of physics experts only create a partial model of physics expertise and does not take into account the development of physics experts in the natural context of research. This dissertation takes a social and cultural perspective of learning through apprenticeship to model the development of physics expertise of physics graduate students in a research group. I use a qualitative methodological approach of an ethnographic case study to observe and video record the …

Data Curation Is For Everyone! The Case For Master's And Baccalaureate Institutional Engagement With Data Curation, Yasmeen Shorish Dec 2012

Data Curation Is For Everyone! The Case For Master's And Baccalaureate Institutional Engagement With Data Curation, Yasmeen Shorish

Yasmeen Shorish

This article describes the fundamental challenges to data curation, how these challenges may be compounded for smaller institutions, and how data management is an essential and manageable component of data curation. Data curation is often discussed within the confines of large, research universities. As a result, master’s and baccalaureate institutions may be left with the impression that they cannot engage with data curation. However, by proactively engaging with faculty, libraries of all sizes can build closer relationships and help educate faculty on data documentation and organization best practices. Experiences from one master’s comprehensive institution as it engages with data management …


Emp And Geomagnetic Storm Protection Of Critical Infrastructure, George H. Baker Iii May 2012

Emp And Geomagnetic Storm Protection Of Critical Infrastructure, George H. Baker Iii

George H Baker

EMP and solar storm wide geographic coverage and ubiquitous system effects beg the question of “Where to begin?” with protection efforts. Thus, in addressing these “wide area electromagnetic (EM) effects,” we must be clever in deciding where to invest limited resources. Based on simple risk analysis, the electric power and communication infrastructures emerge as the highest priority for EM protection. Programs focused on these highest risk infrastructures will go a long way in lessoning societal impact. Given the national scope of the effects, such programs must be coordinated at the national level but implemented at local level. Because wide-area EM …


Consensus In Networks Of Mobile Communicating Agents, Andrea Baronchelli, Albert Diaz-Guilera Apr 2012

Consensus In Networks Of Mobile Communicating Agents, Andrea Baronchelli, Albert Diaz-Guilera

Andrea Baronchelli

Populations of mobile and communicating agents describe a vast array of technological and natural systems, ranging from sensor networks to animal groups. Here, we investigate how a group-level agreement may emerge in the continuously evolving network defined by the local interactions of the moving individuals. We adopt a general scheme of motion in two dimensions and we let the individuals interact through the minimal naming game, a prototypical scheme to investigate social consensus. We distinguish different regimes of convergence determined by the emission range of the agents and by their mobility, and we identify the corresponding scaling behaviors of the …


Wiki Leaks Revelations In Global Context—The War Between ‘Right To Publish’ And ‘Ethical Code Of Conduct, Ratnesh Dwivedi Mr Nov 2011

Wiki Leaks Revelations In Global Context—The War Between ‘Right To Publish’ And ‘Ethical Code Of Conduct, Ratnesh Dwivedi Mr

Ratnesh Dwivedi

WikiLeaks is an international non-profit organisation that publishes submissions of private, secret, and classified media from anonymous news sources, news leaks, and whistleblowers. Its website, launched in 2006 under The Sunshine Press organisation claimed a database of more than 1.2 million documents within a year of its launch. WikiLeaks describes its founders as a mix of Chinese dissidents, journalists, mathematicians, and start-up company technologists from the United States, Taiwan, Europe, Australia, and South Africa. Julian Assange, an Australian Internet activist, is generally described as its director. The site was originally launched as a user-editable wiki, but has progressively moved towards …


A Critical Study Of Organizational Communication And Organizational Communication Theories- A Historical Perspective, Ratnesh Dwivedi Mr Nov 2011

A Critical Study Of Organizational Communication And Organizational Communication Theories- A Historical Perspective, Ratnesh Dwivedi Mr

Ratnesh Dwivedi

Organizational Communication is the study that looks at human communication within and outside the organization. Conrad and Poole (1998) break the definition of organizational communication in parts, by first defining communication and then analyses the organization. These researchers define communication as “a process through which people, acting together, create, sustain, and manage meanings through the use of verbal and nonverbal signs and symbols within a particular context” (Conrad and Poole, 1998, p. 5). In the context of this book, Kenyans and their leaders are communicating their views and final decision through the ballot box to elect their third president, during …


Public Accountability And Media : Its Success And Failure In Performing The Role As A Force For Public Accountability, Ratnesh Dwivedi Mr Nov 2011

Public Accountability And Media : Its Success And Failure In Performing The Role As A Force For Public Accountability, Ratnesh Dwivedi Mr

Ratnesh Dwivedi

Media accountability is a phrase that refers to the general (especially western) belief that mass media has to be accountable in the public’s interest - that is, they are expected to behave in certain ways that contribute to the public good. The concept is not clearly defined, and often collides with commercial interests of media owners; legal issues, such as the constitutional right to the freedom of the press in the U.S.; and governmental concerns about public security and order. Several international organizations, like International Freedom of Expression Exchange, Freedom House, International Press Institute, World Press Freedom Committee and the …


The Penetration Of Social Media In Governance,Political Reforms And Building Public Perception, Ratnesh Dwivedi Mr May 2011

The Penetration Of Social Media In Governance,Political Reforms And Building Public Perception, Ratnesh Dwivedi Mr

Ratnesh Dwivedi

Social media are media for social interaction, using highly accessible and scalable communication techniques. Social media is the use of web-based and mobile technologies to turn communication into interactive dialogue. While we know that social media can play an important role in publicizing political activities such as protests, do we have evidence that such actions have led to substantive political change? Is it possible to develop a set of indicators to more effectively gauge the impact of new technologies and media on questions of political change? That social media can help coordinate large and discrete activities, such as protests and …


Two Faces Of Media While Covering Human Right Activities In India, Ratnesh Dwivedi Mr Apr 2011

Two Faces Of Media While Covering Human Right Activities In India, Ratnesh Dwivedi Mr

Ratnesh Dwivedi

The situation of human rights in India is a complex one, as a result of the country's large size and tremendous diversity, its status as a developing country and a sovereign, secular, democratic republic, and its history as a former colonial territory. The Constitution of India provides for Fundamental rights, which include freedom of religion. Clauses also provide for Freedom of Speech, as well as separation of executive and judiciary and freedom of movement within the country and abroad. In its report on human rights in India during 2010, Human Rights Watch stated India had "significant human rights problems". They …


Language Discourse- A Critical Analysis Of Michel Focault's Work On Language Discourse With Special Reference To His Masterpiece "The Archeology Of Knowledge", Ratnesh Dwivedi Mr Apr 2011

Language Discourse- A Critical Analysis Of Michel Focault's Work On Language Discourse With Special Reference To His Masterpiece "The Archeology Of Knowledge", Ratnesh Dwivedi Mr

Ratnesh Dwivedi

Discourse generally refers to "written or spoken communication or debate". The following are three more specific definitions: (1) In semantics and discourse analysis: A generalization of the concept of conversation to all modalities and contexts. (2) "The totality of codified linguistic usages attached to a given type of social practice. (E.g.: legal discourse, medical discourse, religious discourse.)" (3) In the work of Michel Foucault, and social theorists inspired by him: "an entity of sequences of signs in that they are enouncements (enoncés)" (Foucault 1969: 141). An enouncement (often translated as "statement") is not a unity of signs, but an abstract …

Earth- and space-based observations provide synergistic information for space mission encounters by providing data over longer timescales, at different wavelengths and using techniques that are impossible with an in situ flyby. We report here such observations in support of the EPOXI spacecraft flyby of comet 103P/Hartley 2. The nucleus is small and dark, and exhibited a very rapidly changing rotation period. Prior to the onset of activity, the period was ~16.4 hr. Starting in 2010 August the period changed from 16.6 hr to near 19 hr in December. With respect to dust composition, most volatiles and carbon and nitrogen isotope …


Changing Mutual Perception Of Television News Viewers And Program Makers In India- A Case Study Of Cnn-Ibn And Its Unique Initiative Of Citizen Journalism, Ratnesh Dwivedi Mr Nov 2010

Changing Mutual Perception Of Television News Viewers And Program Makers In India- A Case Study Of Cnn-Ibn And Its Unique Initiative Of Citizen Journalism, Ratnesh Dwivedi Mr

Ratnesh Dwivedi

The Indian television system is one of the most extensive systems in the world. Terrestrial broadcasting, which has been the sole preserve of the government, provides television coverage to over 90% of India's 900 million people. By the end of 1996 nearly 50 million households had television sets. International satellite broadcasting, introduced in 1991, has swept across the country because of the rapid proliferation of small scale cable systems. By the end of 1996, Indians could view dozens of foreign and local channels and the competition for audiences and advertising revenues was one of the hottest in the world. In …


Community Radio:History,Growth,Challenges And Current Status Of It With Special Reference To India, Ratnesh Dwivedi Mr Oct 2010

Community Radio:History,Growth,Challenges And Current Status Of It With Special Reference To India, Ratnesh Dwivedi Mr

Ratnesh Dwivedi

Community radio is a type of radio service that caters to the interests of a certain area, broadcasting content that is popular to a local audience but which may often be overlooked by commercial or mass-media broadcasters. Modern-day community radio stations often serve their listeners by offering a variety of content that is not necessarily provided by the larger commercial radio stations. Community radio outlets may carry news and information programming geared toward the local area, particularly immigrant or minority groups that are poorly served by other major media outlets. Philosophically two distinct approaches to community radio can be discerned, …


History Of Communication And Its Application In Multicultaral,Multilingual Social System In India Across Ages, Ratnesh Dwivedi Mr Sep 2010

History Of Communication And Its Application In Multicultaral,Multilingual Social System In India Across Ages, Ratnesh Dwivedi Mr

Ratnesh Dwivedi

The history of communication dates back to the earliest signs of cavemen.Communication can range from very subtle processes of exchange, to full conversations and mass communication. Human communication was revolutionized with speech perhaps 200,000 years ago, Symbols were developed about 30,000 years ago and writing about 7,000. On a much shorter scale, there have been major developments in the field of telecommunication in the past few centuries.


Multirelational Organization Of Large-Scale Social Networks In An Online World, Renaud Lambiotte Jul 2010

Multirelational Organization Of Large-Scale Social Networks In An Online World, Renaud Lambiotte

Renaud Lambiotte

The capacity to collect fingerprints of individuals in online media has revolutionized the way researchers explore human society. Social systems can be seen as a nonlinear superposition of a multitude of complex social networks, where nodes represent individuals and links capture a variety of different social relations. Much emphasis has been put on the network topology of social interactions, however, the multidimensional nature of these interactions has largely been ignored, mostly because of lack of data. Here, for the first time, we analyze a complete, multirelational, large social network of a society consisting of the 300,000 odd players of a …

Gathering Leadership Momentum Across Great Distances: Creating An Online Community Of Practice, Erin L. Davis, Danielle Theiss-White

Erin Davis

At the 2007 Mountain Plains Library Association Leadership (MPLA) Institute, held in New Mexico, USA, eight academic librarians formed an online multi-state, multigenerational community of practice. MPLA is a twelve-state library association within the United States. Using Google Groups™, the members formed an online environment called the MPLA Community of Practice for continuing development of the leadership skills presented at the Institute. These early-career librarians represent diverse educational backgrounds and work in libraries serving varied populations with differing disciplinary emphases.

The group meets monthly with each member preparing and facilitating online discussions, complete with personal assessments, topical readings, and questions. …


International Terrorism:Role ,Responsibility And Operation Of Media Channles, Ratnesh Dwivedi Mr Nov 2008

International Terrorism:Role ,Responsibility And Operation Of Media Channles, Ratnesh Dwivedi Mr

Ratnesh Dwivedi

"Terrorism" is a term that cannot be given a stable defintion. Or rather, it can, but to do so forstalls any attempt to examine the major feature of its relation to television in the contemporary world. As the central public arena for organising ways of picturing and talking about social and political life, TV plays a pivotal role in the contest between competing defintions, accounts and explanations of terrorism. Which term is used in any particular context is inextricably tied to judgemements about the legitimacy of the action in question and of the political system against which it is directed. …


Investigation Of Stun Guns As Intentional Electromagnetic Interference (Emi) Sources, George H. Baker, Ryan C. Tuttle Jul 2008

Investigation Of Stun Guns As Intentional Electromagnetic Interference (Emi) Sources, George H. Baker, Ryan C. Tuttle

George H Baker

Because the operation and control of most critical infrastructures are highly dependent on electronics, it is important to understand the vulnerability of those electronics to intentional electromagnetic interference (EMI). The possibility of interference using readily available consumer devices is a particular concern. We investigated the feasibility and effectiveness of using compact stun guns to intentionally interfere with electronic systems. Test articles included individual computers and computers networked through a central hub. 60KV and 600KV devices were used in the experiments. Results indicate that stun guns are effective in disabling digital electronic systems.
