Lectures, scientific papers, top secret wartime material, correspondence, and broadcasts are introduced and set in context by Jack Copeland, Director of the Turing Archive for the History of Computing."--Jacket.

Alan Turing, pioneer of computing and WWII codebreaker, is one of the most important and influential thinkers of the twentieth century. In this volume for the first time his key writings are made available to a broad, non-specialist readership. They make fascinating reading both in their own right and for their historic significance: contemporary computational theory, cognitive science, artificial intelligence, and artificial life all spring from this ground-breaking work, which is also rich in philosophical and logical insight.

The prelims comprise: The Birth of the Modern Computer What is a Turing Machine? The Basic Operations of a Turing Machine Human Computation The Church—Turing Thesis Beyond the Universal Turing Machine Misunderstandings of the Church—Turing Thesis: The Limits of Machines Conclusion.

Background:This study is the result of findings from a previous dissertation conducted by this author on Student Nurses’ Unethical Behavior, Boundaries, and Social Media. The use of social media can be detrimental to the nurse–patient relationship if used in an unethical manner.Method:A mixed method, using a quantitative approach based on research questions that explored differences in student nurses’ unethical behavior by age and clinical cohort, the relationship of unethical behavior to the utilization of social media, and analysis on year of (...) birth and unethical behavior. A qualitative approach was used based on a guided faculty interview and common themes of student nurses’ unethical behavior.Participants and Research Context:In total, 55 Associate Degree nursing students participated in the study; the research was conducted at Central Texas College. There were eight faculty-guided interviews.Ethical considerations:The main research instrument was an anonymous survey. All participants were assured of their right to an informed consent. All participants were informed of the right to withdraw from the study at any time.Findings:Findings indicate a significant correlation between student nurses’ unethical behavior and use of social media and a significant difference between student unethical conduct by generation ) and by clinical cohort. Further findings from the follow-up study on year of birth and student unethical behavior reveal a correlation coefficient of 0.384 with a significance level of 0.003.Discussion:Surprisingly, the study found that second-semester students had less unethical behavior than first-, third-, and fourth-semester students. The follow-up study found that this is because second-semester students were the oldest cohort.Conclusion:Implications for positive social change for nursing students include improved ethics education that may motivate ethical conduct throughout students’ careers nationally and globally for better understanding and promotion of ethics and behavior.

In studies of scientific methodology, surprisingly little attention has been given to tests of hypotheses. Such testing constitutes a methodology common to various scientific disciplines and is an essential factor in the development of science since it determines which theories are retained. The classical theory of tests is a major accomplishment but requires modification in order to produce a theory that accounts for the success of science. The revised theory is an analysis of the nondeductive aspect of scientific reasoning. It (...) results in a new definition of probability and a nonclassical point of view with regard to the foundations of probability. (shrink)

Many philosophers contend that Turing’s work provides a conceptual analysis of numerical computability. In (Rescorla, 2007), I dissented. I argued that the problem of deviant notations stymies existing attempts at conceptual analysis. Copeland and Proudfoot respond to my critique. I argue that their putative solution does not succeed. We are still awaiting a genuine conceptual analysis.

In their recent paper “Do Accelerating Turing Machines Compute the Uncomputable?” Copeland and Shagrir draw a distinction between a purist conception of Turing machines, according to which these machines are purely abstract, and Turing machine realism according to which Turing machines are spatio-temporal and causal “notional" machines. In the present response to that paper we concede the realistic aspects of Turing’s own presentation of his machines, pointed out by Copeland and Shagrir, but argue that Turing's treatment of symbols (...) in the course of that presentation opens the door for later purist conceptions. Also, we argue that a purist conception of Turing machines plays an important role not only in the analysis of the computational properties of Turing machines, but also in the philosophical debates over the nature of their realization.

It is well-known that different social choice procedures often result in different choice sets. The article focuses on how often this is likely to happen in impartial cultures. The focus is on Borda count, plurality method, max-min method and Copeland's procedure. The probabilities of Condorcet violations of the Borda count and plurality method are also reported. Although blatantly false as a descriptive hypothesis, the impartial culture assumption can be given an interpretation which makes the results obtained in impartial cultures (...) particularly significant, viz. the probabilities of deviations in choice sets indicate how far apart are the intuitions underlying various choice procedures. -/- .

The difficulty of making social choices seems to take on two forms: one that is related to both preferences and the method used in aggregating them and one which is related to the preferences only. In the former type the difficulty has to do with the discrepancies of outcomes resulting from various preference aggregation methods and the computation of winners in elections. Some approaches and results which take their motivation from the computability theory are discussed. The latter ‘institution-free’ type of (...) difficulty pertains to solution theory of the voting games. We discuss the relationships between various solution concepts, e.g. uncovered set, Banks set, Copeland winners. Finally rough sets are utilized in an effort to measure the difficulty of making social choices. (shrink)

In this volume, Elizabeth Phillips brings together scholarly essays on eschatology, ethics, and politics, as well as a selection of sermons preached in the chapels of the University of Cambridge arising from that scholarly work. These essays and sermons explore themes ranging from ethnography to Anabaptism and Christian Zionism to Afro-pessimism. Drawing on a wide range of authors from Flannery O'Conner and Herbert McCabe to James Cone and M. Shawn Copeland, this collection provides insight into the fields of Christian (...) ethics and political theology, as well as ethnography and homiletics. Phillips challenges theologians to interdisciplinarity in their work, and to keep historical and traditional sources in conversation with contemporary sources from critical and liberative perspectives. She challenges Christians to engage in apocalyptic practices which name and resist the false pretenses of the political status quo. And she challenges preachers to call their congregations to moral and political faithfulness, opening up possibilities beyond both the squeamish evasion of politics in some preaching traditions and the didactic political partisanship of others."--Publisher's website.

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:The Scandal of White Complicity in US Hyper-Incarceration: A Nonviolent Spirituality of White Resistance by Alex Mikulich, Laurie Cassidy, and Margaret PfeilNancy M. RourkeThe Scandal of White Complicity in US Hyper-Incarceration: A Nonviolent Spirituality of White Resistance Alex Mikulich, Laurie Cassidy, and Margaret Pfeil new york: palgrave macmillan, 2013. 203 pp. $90.00As a white American Catholic ethicist, I often envy my Protestant counterparts’ legacy of acknowledging and fighting (...) racism. Catholic moral theology lacks Protestantism’s bodies of literature, activism, and bold ecclesial statements addressing racism in the United States. (For more on this, see Bryan Massingale’s Racial Justice and the Catholic Church.) The Scandal of White Complicity in US Hyper-Incarceration demonstrates how Catholicism might approach American racism using several elements of Catholic theology.The book opens with series editor Mary Jo Iozzo’s introduction to the Content and Context in Theological Ethics series, of which this is the fifth book. A personal and reflective foreword by Sr. Helen Prejean follows. Then the book’s argument begins with a description of the United States’ practice of mass incarceration and brief discussions of what is meant by “whiteness” and “complicity.” This book employs a phenomenological understanding of race and of whiteness, taking whiteness as habitus. The literature about this approach to race and to identity is enormous, but familiarity with that literature is not necessary to follow this book’s presentation, argument, or use of the idea.Each of the book’s three authors has written a two-chapter section. Alex Mikulich’s explanation of white habitus speaks on levels of social thought and of the individual’s experience. Laurie Cassidy’s section looks at the culture of hyperincarceration and the development of the “dangerous black man” myth, and Margaret Pfeil’s section on spirituality works from the beatitudes, John of the Cross, and a wide array of other sources to describe a political spirituality of resistance for white Christians.This book would be most useful to masters-level graduate students in theological ethics or anyone preparing to begin teaching in areas of ethics related to racism or criminal justice (particularly in Catholic institutional settings). Rather than drawing exclusively on Catholic social teaching to talk about white participation in racism, these authors more satisfyingly put many Catholic traditions into action. For example, the book demonstrates careful use of the concepts of complicity, responsibility, participation, and intention; it considers specific [End Page 195] actions while maintaining focus on systems’ structures; and it uses a wide range of Catholic thinkers, including Metz, Copeland, Soelle, Gutiérrez, Carmelite Sr. Constance FitzGerald, Lonergan, Day, and John of the Cross.This book assumes and asserts that racism still exists, that whiteness exists and aims to make itself invisible, and that racism is kept alive through social structures that flow from white habitus. However, the book does not assume the reader’s agreement with any of these. Instead, the book first makes the case that these things are true and then takes next steps toward responsive practices of resistance. Rhetorically tinged homiletic shortcuts are not used to bolster this argument. For example, in similar works, the question of moral culpability for racist social structures is sometimes managed only with a discussion of how such structures distribute benefits and harms unequally. In this book, that argument is not used alone but in tandem with a careful look at the intention of one’s participation in such structures.Minor problems exist. The book would have benefited from one more round of editing to eliminate minor punctuation and writing problems, and the Catholic moral concept of “scandal” receives little systematic attention despite its presence in the title. Otherwise, the book demonstrates well what Catholic moral theology could do if applied to American white racism. Here’s hoping that this is just the beginning of more such scholarship.Nancy M.

We identify a new monotonicity condition (called cover monotonicity) for tournament solutions which allows a discrimination among main tournament solutions: The top-cycle, the iterated uncovered set, the minimal covering set, and the bipartisan set are cover monotonic while the uncovered set, Banks set, the Copeland rule, and the Slater rule fail to be so. As cover monotonic tournament solutions induce social choice rules which are Nash implementable in certain non-standard frameworks (such as those set by Bochet and Maniquet (CORE (...) Discussion Paper No. 2006/84, 2006) or Özkal-Sanver and Sanver (Social Choice and Welfare, 26(3), 607–623, 2006), the discrimination generated by cover monotonicity becomes particularly notable when implementability is a concern.
