While writing the foreword for this special edition of the International Journal for the Semiotics of Law, I was informed of Dr. Nelson R. Mandela’s death. While saddened with his passing, I was struck by the fact, he was one of the two men who most influenced my study and practice of Restorative Justice; the other was my father. Both passed away while this edition was compiled and edited.In the mid 1990s, I first read about Restorative Justice as an aspect (...) of the Truth and Reconciliation Commission (“TRC”) established by Dr. Mandela in post-apartheid South Africa. I was fascinated by his forgiveness of his oppressors and how he infused the ideals of reconciliation and forgiveness into a court-like hearing. It was an opportunity for the victim of human rights violations to face the perpetrator and tell the perpetrator the extent of the injuries he or she suffered. After the victim spoke, the perpetrator had an opportunity to admit to the wrongdoing, take full responsibility for the har. (shrink)

Ethics is a significant issue among those in leadership positions, especially since the ethical corporate scandals of the 1970s followed by corporate scandals in the 1980s and the S&L scandals of the 1980s and 1990s and most recently the global financial crisis of 2006–2009. The purpose of this research was to measure the perceived leadership integrity in today’s manufacturing environment, since the global financial crisis, as perceived by their employees. This study included 7,233 manufacturing employees in the United States. A (...) total of 66 surveys were used to calculate data for this study. The Perceived Leader Integrity Scale (PLIS) was used to collect data from respondents that included demographic questions. The research addressed the following question: To what degree are leaders in the manufacturing industry considered “low ethical,” “moderate ethical,” and “high ethical” on the PLIS? (shrink)

Ethics has been identified as a significant issue among those in leadership positions. The purpose of this research was to assess the ethics and integrity of leaders in today's manufacturing environment as perceived by their employees. This study included a total of 10 manufacturing companies in the United States. A total of 59 surveys were used to calculate data for this study. A demographic survey and the Perceived Leader Integrity Scale (PLIS) were used to collect data from respondents. The research (...) addressed the following question: To what degree are leaders in the manufacturing industry considered "low ethical," "moderate ethical," and "high ethical" on the PLIS? It was determined through descriptive data analysis that the majority of supervisors in this study, as rated by their employees were highly ethical. Male and female employees equally rated their supervisors as highly ethical. Employees in the age category (18-25) rated their supervisors higher ethically than other age groups in the study. However, considering ethnicity categories, African-Americans scored their supervisors lower ethically than the European-American category. The education level of the employees did not provide any significant findings in rating their supervisors. (shrink)

When people argue they routinely challenge the opinions, views, and attitudes of one another, they seek to cast the other as the aggressor or party at fault, and otherwise exert social control. This article illustrates how members work to hamper challenges, evade control or avoid being negatively characterized by systematically blocking access to a turn in the third position and stopping their opponent’s agenda. Examining 100 hours of public disputes in varieties of English, I use membership categorization analysis and conversation (...) analysis to unpack resistance as part of the structural organization of disputes. I identify two methods of resisting an agenda: passively, whereby a responsive turn stalls the progressivity of the interaction, and actively, whereby a responsive turn disaligns to outrightly suspend the progressivity of the interaction. I discuss how resistance sequentially unfolds across sequential positions, and as an interactional phenomenon which solves the trouble of a challenge. Overall, this article contributes to social interaction research on resistance, public disputes and how social order is constituted in and through talk-in-interaction. (shrink)

The literature on brain activity in depression and anxiety is reviewed with an on highlighting discrepancies and inconsistencies. In particular, and posterior asymmetries have been reported for both depression anxiety, but the magnitude and direction of these asymmetries has been We propose that by identifying subtypes of depression and anxiety of these inconsistencies can be explained. In addition, we review suggesting that issues of comorbidity are important to consider in to account for regional brain activity in depression and anxiety.

In the field of Conflict Transformation, Restorative Justice is often perceived as a transformative process focused on healing relationships after a specific harm. The parties considered in a RJ setting are those harmed, those responsible and the community impacted. This is particularly true in the field of criminal and transitional justice, and in an extended and spiritual view, there is reconciliation with the parties and God. Despite cultural differences, RJ theory and concepts have been accepted favorably in the many countries. (...) From a viewpoint focused on methodology and process, however, cultural differences have a significant effect for implementation. For example, important concepts such as control, choice, harm, responsibility, apology, shame, reconciliation and forgiveness vary greatly in the manner in which they are perceived from culture to culture and may create obstacles for successful implementation of a successful process when one culture’s process and definitions are forced upon another. Therefore, promotional factors and the implication of semiotics are an absolute consideration in developing a RJ process within a particular culture. This paper discusses the cultural differences between the United States and Japan with regard to semiotic obstacles in the implementation of a RJ model in the Japanese criminal justice system. While the exploration of cultural differences, particularly between the United States and Japan is not new and has been the focus of many disciplines, little has been considered regarding the assimilation and implementation of a Western RJ model into the Eastern culture of Japan. In sum, is an attempt to clarify and integrate the effects of cultural differences for some factors as they apply to a RJ based reconciliation process focused in Semiotics, Social psychology and the Sociology of law as they apply to the United States and Japan.

BACKGROUND: Alzheimer's disease is intimately tied to amyloid-beta peptide. Extraneuronal brain plaques consisting primarily of Abeta aggregates are a hallmark of AD. Intraneuronal Abeta subunits are strongly implicated in disease progression. Protein sequence mutations of the Abeta precursor protein account for a small proportion of AD cases, suggesting that regulation of the associated gene may play a more important role in AD etiology. The APP promoter possesses a novel 30 nucleotide sequence, or "proximal regulatory element" , at -76/-47, from the (...) +1 transcription start site that confers cell type specificity. This PRE contains sequences that make it vulnerable to epigenetic modification and may present a viable target for drug studies. We examined PRE-nuclear protein interaction by gel electrophoretic mobility shift assay and PRE mutant EMSA. This was followed by functional studies of PRE mutant/reporter gene fusion clones. RESULTS: EMSA probed with the PRE showed DNA-protein interaction in multiple nuclear extracts and in human brain tissue nuclear extract in a tissue-type specific manner. We identified transcription factors that are likely to bind the PRE, using competition gel shift and gel supershift: Activator protein 2 , nm23 nucleoside diphosphate kinase/metastatic inhibitory protein , and specificity protein 1 . These sites crossed a known single nucleotide polymorphism . EMSA with PRE mutants and promoter/reporter clone transfection analysis further implicated PuF in cells and extracts. Functional assays of mutant/reporter clone transfections were evaluated by ELISA of reporter protein levels. EMSA and ELISA results correlated by meta-analysis. CONCLUSIONS: We propose that PuF may regulate the APP gene promoter and that AD risk may be increased by interference with PuF regulation at the PRE. PuF is targeted by calcium/calmodulin-dependent protein kinase II inhibitor 1, which also interacts with the integrins. These proteins are connected to vital cellular and neurological functions. In addition, the transcription factor PuF is a known inhibitor of metastasis and regulates cell growth during development. Given that APP is a known cell adhesion protein and ferroxidase, this suggests biochemical links among cell signaling, the cell cycle, iron metabolism in cancer, and AD in the context of overall aging.

Any instance (i.e., event, behavior, trait) belongs to infinitely many reference classes, hence there are infinitely many base rates from which to choose. People clearly do not entertain all possible reference classes, however, so something must be limiting the search space. We suggest some possible mechanisms that determine which reference class is evoked for the purpose of judgment and decision.

In order to introduce protists to philosophers, we outline the diversity, classification, and evolutionary importance of these eukaryotic microorganisms. We argue that an evolutionary understanding of protists is crucial for understanding eukaryotes in general. More specifically, evolutionary protistology shows how the emphasis on understanding evolutionary phenomena through a phylogeny-based comparative approach constrains and underpins any more abstract account of why certain organismal features evolved in the early history of eukaryotes. We focus on three crucial episodes of this history: the origins (...) of multicellularity, the origin of sex, and the origin of the eukaryote cell. Despite ongoing uncertainty about where the root of the eukaryote tree lies, and residual questions about the precise endosymbioses that have produced a diversity of photosynthesizing eukaryotes, evolutionary protistology has illuminated with considerable clarity many aspects of protist evolution. Our main message in light of evolutionary protistology is that these ‘other eukaryotes’ are in fact the organisms through which the rest of the eukaryotes should be understood. (shrink)

There are various equivalent formulations of the Church-Turing thesis. A common one is that every effective computation can be carried out by a Turing machine. The Church-Turing thesis is often misunderstood, particularly in recent writing in the philosophy of mind.

Presupposing no familiarity with the technical concepts of either philosophy or computing, this clear introduction reviews the progress made in AI since the inception of the field in 1956. Copeland goes on to analyze what those working in AI must achieve before they can claim to have built a thinking machine and appraises their prospects of succeeding.There are clear introductions to connectionism and to the language of thought hypothesis which weave together material from philosophy, artificial intelligence and neuroscience. John Searle's (...) attacks on AI and cognitive science are countered and close attention is given to foundational issues, including the nature of computation, Turing Machines, the Church-Turing Thesis and the difference between classical symbol processing and parallel distributed processing. The book also explores the possibility of machines having free will and consciousness and concludes with a discussion of in what sense the human brain may be a computer. (shrink)

To compute is to execute an algorithm. More precisely, to say that a device or organ computes is to say that there exists a modelling relationship of a certain kind between it and a formal specification of an algorithm and supporting architecture. The key issue is to delimit the phrase of a certain kind. I call this the problem of distinguishing between standard and nonstandard models of computation. The successful drawing of this distinction guards Turing's 1936 analysis of computation against (...) a difficulty that has persistently been raised against it, and undercuts various objections that have been made to the computational theory of mind.

Perspectives on Quine, now available in paperback, is a collection of twenty-one new essays dealing with the thought of America's most distinguished living philosopher, Willard Van Orman Quine. After the editors' brief introduction to Quine's thought, the volume opens with an important new essay by Quine entitled Three Indeterminacies. The essays that follow, written by leading philosophers, are rich with insights into a wide variety of Quine's concerns ranging from logic and set theory to natural language, truth, evidence, natural kinds, (...) naturalized epistemology, and much more. Each essay concludes with a summary and response from Quine himself. (shrink)

A survey of the field of hypercomputation, including discussion of a variety of objections.

Turing''s test has been much misunderstood. Recently unpublished material by Turing casts fresh light on his thinking and dispels a number of philosophical myths concerning the Turing test. Properly understood, the Turing test withstands objections that are popularly believed to be fatal.

Accelerating Turing machines have attracted much attention in the last decade or so. They have been described as “the work-horse of hypercomputation” (Potgieter and Rosinger 2010: 853). But do they really compute beyond the “Turing limit”—e.g., compute the halting function? We argue that the answer depends on what you mean by an accelerating Turing machine, on what you mean by computation, and even on what you mean by a Turing machine. We show first that in the current literature the term (...) “accelerating Turing machine” is used to refer to two very different species of accelerating machine, which we call end-stage-in and end-stage-out machines, respectively. We argue that end-stage-in accelerating machines are not Turing machines at all. We then present two differing conceptions of computation, the internal and the external, and introduce the notion of an epistemic embedding of a computation. We argue that no accelerating Turing machine computes the halting function in the internal sense. Finally, we distinguish between two very different conceptions of the Turing machine, the purist conception and the realist conception; and we argue that Turing himself was no subscriber to the purist conception. We conclude that under the realist conception, but not under the purist conception, an accelerating Turing machine is able to compute the halting function in the external sense. We adopt a relatively informal approach throughout, since we take the key issues to be philosophical rather than mathematical. (shrink)

Accelerating Turing machines are Turing machines of a sort able to perform tasks that are commonly regarded as impossible for Turing machines. For example, they can determine whether or not the decimal representation of contains n consecutive 7s, for any n; solve the Turing-machine halting problem; and decide the predicate calculus. Are accelerating Turing machines, then, logically impossible devices? I argue that they are not. There are implications concerning the nature of effective procedures and the theoretical limits of computability. Contrary (...) to a recent paper by Bringsjord, Bello and Ferrucci, however, the concept of an accelerating Turing machine cannot be used to shove up Searle's Chinese room argument. (shrink)

Turing’s analysis of computability has recently been challenged; it is claimed that it is circular to analyse the intuitive concept of numerical computability in terms of the Turing machine. This claim threatens the view, canonical in mathematics and cognitive science, that the concept of a systematic procedure or algorithm is to be explicated by reference to the capacities of Turing machines. We defend Turing’s analysis against the challenge of ‘deviant encodings’.Keywords: Systematic procedure; Turing machine; Church–Turing thesis; Deviant encoding; Acceptable encoding; (...)

What are the limits of physical computation? In his ‘Church’s Thesis and Principles for Mechanisms’, Turing’s student Robin Gandy proved that any machine satisfying four idealised physical ‘principles’ is equivalent to some Turing machine. Gandy’s four principles in effect define a class of computing machines (‘Gandy machines’). Our question is: What is the relationship of this class to the class of all (ideal) physical computing machines? Gandy himself suggests that the relationship is identity. We do not share this view. We (...) will point to interesting examples of (ideal) physical machines that fall outside the class of Gandy machines and compute functions that are not Turing-machine computable. (shrink)

Searle has recently used two adaptations of his Chinese room argument in an attack on connectionism. I show that these new forms of the argument are fallacious. First I give an exposition of and rebuttal to the original Chinese room argument, and then a brief introduction to the essentials of connectionism.
