Relationship of nine constants  [PDF]
Michael Snyder
Natural Science (NS) , 2013, DOI: 10.4236/ns.2013.59117

Through the process of trial and error, four unitless equations made up of nine constants have been found with exact answers. The related constants are the Speed of Light [1], the Planck constant [2], Wien’s displacement constant [3], Avogadro’s number [4], the universal Gravity constant [5], the Ampere constant [6], the Faraday constant [7], the Gas constant [8] and Apery’s constant [9].

Leukemia and Benzene
Robert Snyder
International Journal of Environmental Research and Public Health , 2012, DOI: 10.3390/ijerph9082875
Abstract: Excessive exposure to benzene has been known for more than a century to damage the bone marrow resulting in decreases in the numbers of circulating blood cells, and ultimately, aplastic anemia. Of more recent vintage has been the appreciation that an alternative outcome of benzene exposure has been the development of one or more types of leukemia. While many investigators agree that the array of toxic metabolites, generated in the liver or in the bone marrow, can lead to traumatic bone marrow injury, the more subtle mechanisms leading to leukemia have yet to be critically dissected. This problem appears to have more general interest because of the recognition that so-called “second cancer” that results from prior treatment with alkylating agents to yield tumor remissions, often results in a type of leukemia reminiscent of benzene-induced leukemia. Furthermore, there is a growing literature attempting to characterize the fine structure of the marrow and the identification of so called “niches” that house a variety of stem cells and other types of cells. Some of these “niches” may harbor cells capable of initiating leukemias. The control of stem cell differentiation and proliferation via both inter- and intra-cellular signaling will ultimately determine the fate of these transformed stem cells. The ability of these cells to avoid checkpoints that would prevent them from contributing to the leukemogenic response is an additional area for study. Much of the study of benzene-induced bone marrow damage has concentrated on determining which of the benzene metabolites lead to leukemogenesis. The emphasis now should be directed to understanding how benzene metabolites alter bone marrow cell biology.
Antes, agora, adiante: hipertexto, letramento e mudan?a

Educa??o em Revista , 2010, DOI: 10.1590/S0102-46982010000300013
Abstract: this paper considers the complex connections between hypertext, literacy and educational change. it begins with four stories that illuminate some of the challenges that confront the field of hypertext research: notably, literacy teachers' tendency to conservatism in their pedagogical practices and the remarkable cultural endurance of the printed book. the paper asks: how might literacy educators do more than shuffle into the future? a number of suggestions are offered: devise a common language to talk about the changes to literacy practices associated with the use of new media; identify theories that help explain the changes to literacy practices in the digital age; suggest a direction for the third generation of hypertext research and theory. the first generation of hypertext research and theory produced some elegant and evocative ideas but made too many claims. the second generation took another look at hypertext, but this time in the unbounded context of the internet. too often, however, it clung to old ideas that no longer made sense in the new on-line environment. the third generation promises to demonstrate how productive it can be to traverse traditional disciplinary and theoretical boundaries in pursuit of new understandings of on-line literacy designed to inform teaching and learning.

The Digital Culture and Communication: More than just Classroom Learning
Kristen Snyder
Seminar.net , 2005,
Abstract: This paper presents a conceptual model of the digital culture that reflects the multi-dimensionality of ICT in education: pedagogy, communication, technology and organizational systems. The model grew out of a three-year study of an online professional development program for educators in seven countries. The focus of the paper is to explore the relationship between human dynamics and technological systems for advancing the school as an organization. Considering the digital culture of schools from an organizational communication culture perspective awakens us to the importance of looking at the subculture that emerges through human exchange reflecting core values and beliefs. When we consider the digital world in which students already live, and match it against the challenge of schools for human citizen development, we begin to see that a digital culture is more than technological. It is organizational, it is communicative, and it is cultural. Through the creation of cultural webs, motivated by humans, and assisted by technology, online communication has the possibility to shape a collective space for cross cultural connections that support a shared democracy.
The Ethics Of Reconciling : Learning From Canada’s Truth And Reconciliation Commission
Emily Snyder
Les Ateliers de l’éthique , 2010,
Abstract: In 2008, the Truth and Reconciliation Commission of Canada (TRC) was initiated to address the historical and contemporary injustices and impacts of Indian Residential Schools. Of the many goals of the TRC, I focus on reconciliation and how the TRC aims to promote this through public education and engagement. To explore this, I consider two questions:1) who does the TRC include in the process of reconciliation? And 2) how might I, as someone who is not Indigenous (specifically, as someone who is “white”), be engaged by the TRC?Ethical queries arise which speak to broader concerns about the TRC’s capability to fulfill its public education goals. I raise several concerns about whether the TRC’s plan to convoke the col- lective will result in over-simplifying the process by relying on blunt, poorly defined identity cate- gories that erase the heterogeneity of those residing in Canada, as well as the complexity of the conflict among us. I attempt to situate myself in-between proclamations of “success” or “failure” of the TRC, to better understand what can be learned from contested truths and experiences of uncertainty.

The Digital Culture and “Peda-Socio” Transformation
Kristen Snyder
Seminar.net , 2007,
Abstract: This paper presents a concept called the digital culture, which emerged during a five-year research project of online professional development networks for educators. Turning first to a discussion about the digital culture model, I suggest that technology is no longer solely a separate, objective entity in society. The integration of technology in human communication engages technology as part of the communication act and therefore as part of the process of creating meaning. Developing an awareness of the implications for behavior, norms and values, and meaning making is integral to understanding the digital culture. Following a conceptual explanation of the digital culture model, I explore the implications for education, both in relation to opportunities and points of concern. My intent in this paper is to raise awareness and stimulate dialogue among educators about the need to see technology integrated with pedagogy, communication, and organizational systems. While considerable research has addressed dimensions of technology in learning and societal development, educational systems have yet to develop a holistic model that integrates all four. I suggest that this is a missed opportunity not only for schools, but also for engaging youth in lifelong learning and social transformation.
Groups with a Character of Large Degree
Noah Snyder
Mathematics , 2006,
Abstract: Let G be a finite group of order n and V an irreducible representation over the complex numbers of dimension d. For some nonnegative number e, we have n=d(d+e). If e is small, then the character of V has unusually large degree. We fix e and attempt to classify such groups. For e<=3 we give a complete classification. For any other fixed e we show that there are only finitely many examples.
A rotational approach to triple point obstructions
Noah Snyder
Mathematics , 2012,
Abstract: Subfactors where the initial branching point of the principal graph is 3-valent are subject to strong constraints called triple point obstructions. Since more complicated initial branches increase the index of the subfactor, triple point obstructions play a key role in the classification of small index subfactors. There are two strong triple point obstructions called the triple-single obstruction and the quadratic tangles obstruction. Although these obstructions are very closely related, neither is strictly stronger. In this paper we give a more general triple-point obstruction which subsumes both. The techniques are a mix of planar algebraic and connection-theoretic techniques with the key role played by the rotation operator.
