Hird, G.R., Recursive properties of relations on models, Annals of Pure and Applied Logic 63 241–269. We prove general existence theorems for recursive models on which various relations have specified recursive properties. These capture common features of results in the literature for particular algebraic structures. For a useful class of models with new relations R, S, where S is r.e., we characterize those for which there is a recursive model isomorphic to on which the relation corresponding to S remains (...) r.e., while that corresponding to R is not r.e.; immune; hyperimmune. The results are applied to vector spaces, Boolean algebras and abelian groups. In the case of vector spaces, this leads to a new kind supermaximal subspace of V∞. (shrink)

In prior papers the following question was considered: which classes of computable sets can be learned if queries about those sets can be asked by the learner? The answer depended on the query language chosen. In this paper we develop a framework for studying this question. Essentially, once we have a result for queries to [S,<]2, we can obtain the same result for many different languages. We obtain easier proofs of old results and several new results. An earlier result we (...) have an easier proof of: the set of computable sets cannot be learned with queries to the language [+,<] . A new result: the set of computable sets cannot be learned with queries to the language [+,<,POWa] where POWa is the predicate that tests if a number is a power of a. (shrink)

This purely theoretical paper examines the relationship between the pursuit of entrepreneurial opportunity and environmental impact. Specifically, we attempt to more effectively define environmentally-relevant entrepreneurship through comparisons of different extant definitions in the literature, and to extend Schumpeterian theory through the inclusion of environmental entrepreneurship within his framework. By doing so, we contribute to the entrepreneurship literature through a more encompassing and specified definition of environmental entrepreneurship, and by incorporating environmental entrepreneurship into Schumpeter’s (1934) theoretical framework. We propose that (1) (...) Waste-Equals-Food, (2) Public Goods, and (3) Externalities each demonstrate thatenvironmental entrepreneurship is the act of creating future goods and services with positive environmental consequences. Finally, we assert that Schumpeter would likely characterize the pursuit of any such opportunity as “opening up a new source of supply.”. (shrink)

The statements and arguments based on experimental evidence used to support the claim that the 3d sub-level is below the 4s sub-level in scandium are examined. The flaw in all the arguments is that they assume the order in which the 3d and 4s sub-levels arrange remains the same in both the neutral atom and in its ions. Analysis of the ground and excited states of atomic spectra shows that as the number of electrons relative to the nuclear charge increases, (...) the 3d level moves higher in energy relative to the 4s level. It is perfectly possible that in a neutral scandium atom the 3d sub-level is above the 4s sub-level and that when it ionizes the energy levels simultaneously rearrange during the process. (shrink)

Terrorism is a notoriously plastic word, depending on user, audience, and political context. This paper focuses on shifts in its meanings since the early 1970s. As federal statutes made terrorism a criminal offense, common usage changed from a broad meaning to one that specified terrorism as a political crime. The argument is that the state shapes meaning and public discourse through law. Peircean semiotics and the semiotic philosophy of Russian linguist Vološinov provide a framework to explore relationships among politics, law, (...) and civil life. Applied to the events of September 11, 2001 such an analysis further allows better understanding of certain interpreters of the September 11 attacks, notably Jean Baudrillard, Jacques Derrida, and Jürgen Habermas.

I will here apply the classical Indian model of the dramatic actor as a methodology for interpreting the soteriological psychology of the Bhagavad Gītā, paying special attention to the usefulness of this approach for clarifying Kṛṣṇa's rationale in showing his divine form in Chapter 11. I argue that the Gītā advocates creative role-play as both the means and the end of liberation. Further, while Kṛṣṇa's teachings can be understood in terms of orthodox Hindu soteriologies that have in view an overcoming (...) of the emotions, I argue that Kṛṣṇa looks to transform Arjuna into an ‘athlete of emotion’, much like traditional Indian-based training methods do for theatrical actors.

This methodological essay describes and advocates using certain psychoanalytic techniques for ethnography. It focuses on the self analysis of the ethnographer using evenly hovering attention, dream analysis, and free association. It presents an argument that using those techniques enhances the goal of ethnography as a human science and of social research. Fear of crime serves as a point of departure for the methodological argument. Finally, it links psychoanalytic ethnography to a fractal model of society and the self with reference to (...) C. S. Peirce’s theory of semiotics as a link between the individual and society. (shrink)

The two-phase study reported here examined the content and communication function served by electronic bumper stickers. EBSs consist of the sayings that are included in an e-mail signature file following personal identifiers such as one's name, phone number, and postal address. In the first phase, 334 EBSs were gathered and content analyzed into one of five message categories. In order of frequency they were: wisdom, humor, advice, religious, and socio-political commentary. In the second phase, open-ended responses from 134 EBS users (...) were coded into one of six motives for interpersonal communication. The relationship between one's motive for using an EBS and the content of one's EBS was not statistically significant. The implications of EBSs and e-mail use for mediated communication competence are considered. (shrink)

The current study examines patterns of attachment/self-protective strategies and rates of unresolved loss/trauma in children and adolescents presenting to a multidisciplinary gender service. Fifty-seven children and adolescents (8.42–15.92 years; 24 birth-assigned males and 33 birth-assigned females) presenting with gender dysphoria participated in structured attachment interviews coded using dynamic-maturational model (DMM) discourse analysis. The children with gender dysphoria were compared to age- and sex-matched children from the community (non-clinical group) and a group of school-age children with mixed psychiatric disorders (mixed psychiatric (...) group). Information about adverse childhood experiences (ACEs), mental health diagnoses, and global level of functioning was also collected. In contrast to children in the non-clinical group, who were classified primarily into the normative attachment patterns (A1-2, B1-5, and C1-2) and who had low rates of unresolved loss/trauma, children with gender dysphoria were mostly classified into the high-risk attachment patterns (A3-4, A5-6, C3-4, C5-6, and A/C) (χ2= 52.66;p< 0.001) and had a high rate of unresolved loss/trauma (χ2= 18.64;p< 0.001). Comorbid psychiatric diagnoses (n= 50; 87.7%) and a history of self-harm, suicidal ideation, or symptoms of distress were also common. Global level of functioning was impaired (range 25–95/100; mean = 54.88;SD= 15.40; median = 55.00). There were no differences between children with gender dysphoria and children with mixed psychiatric disorders on attachment patterns (χ2= 2.43;p= 0.30) and rates of unresolved loss and trauma (χ2= 0.70;p= 0.40).Post hocanalyses showed that lower SES, family constellation (a non-traditional family unit), ACEs—including maltreatment (physical abuse, sexual abuse, emotional abuse, neglect, and exposure to domestic violence)—increased the likelihood of the child being classified into a high risk attachment pattern. Akin to children with other forms of psychological distress, children with gender dysphoria present in the context of multiple interacting risk factors that include at-risk attachment, unresolved loss/trauma, family conflict and loss of family cohesion, and exposure to multiple ACEs.

Gender dysphoria (GD) is marked by an incongruence between a person’s biological sex at birth, and their felt gender (or gender identity). There is continuing debate regarding the benefits and drawbacks of physiological treatment of GD in children, a pathway, beginning with endocrine treatment to suppress puberty. Currently, the main alternative to physiological treatment consists of the so-called “wait-and-see” approach, which often includes counseling or other psychotherapeutic treatment. In this paper, we argue in favor of a “third pathway” for the (...) diagnosis and treatment of GD in youths. To make our case, we draw on a recent development in bioethics: the phenomenological approach. Scholars such as Slatman and Svenaeus have argued that the extent to which the body can (or should be) manipulated or reconstructed through medical intervention is not only determined by consideration of ethical frameworks and social and legal norms. Rather, we must also take account of patients’ personal experience of their body, the personal and social values associated with it, and their understanding of its situation in their life: their narrative identities. We apply this phenomenological approach to medicine and nursing to the diagnosis and treatment of GD in youth. In particular, we discuss Zahavi and Martiny’s conception of the phenomenological interview, in order to show that narrative techniques can assist in the process of gender identification and in the treatment of youth presenting with GD. We focus on two case studies that highlight the relevance of a narrative-based interview in relations between patients, HCPs, and family, to expose the influence of social ideologies on how young people presenting with GD experience their bodies and gender.

We conducted a survey of residents of Kingston, Ontario, Canada, (n = 107) to understand their attitudes to and experiences of waste management and governance. Currently, the municipality is emphasising waste diversion and exploring new waste processing systems (WPS; e.g., incineration) to reduce costs. Using Foucault's governmentality theory, our data suggest Kingston's reliance on an attitude-behaviour-context model of behaviour change successfully fosters an environmental citizenship identity based on waste diversion (e.g., recycling). However, we argue that the neoliberal governmentality upon which (...) the attitude-behaviour-context model is predicated elides the need for, and inhibits consideration of, broader societal change concerning urgent environmental issues involving consumption and waste.

We draw on the behavioral agency model to explore the ethical consequences of CEO equity incentives. We argue that CEOs are more concerned with funding pension plans when they have more to gain from their stock options yet will increasingly underfund employee pension funds as their current option wealth increases. Our findings reveal that both effects hold when the CEO has greater power (also occupying board chair) over firm decision making. Our study suggests that there is an ethical dimension to (...) equity incentives, given they are intended to align CEO interests with shareholders, yet potentially incentivize CEO behaviors with adverse consequences for employees. Insights from our findings provide boards and regulators with behavioral levers to protect employee well-being in the context of pension funding. (shrink)

Les professeurs Macey et Miller analysent la relation entre l’assurance des dépôts et l’ inadé quation dans la structure des échéances des actifs et passifs des banques commerciales. Après avoir critiqué l’hypothèse traditionnelle concernant la réglementation, d’après laquelle les banques sont incitées à financer les actifs à long terme par des passifs à court terme parce que l’assurance des dépôts garantie par l’Etat stimule le crédit des banques et subventionne les passifs à court terme, ils utilisent l’analyse économique des décisions (...) publiques pour soutenir qu’une version modifiée de l’hypothèse de la réglementation est la meilleure explication de la déstructuration des échéances des actifs et passifs bancaires.Finalement, ils considèrent que soutenir l’hypothèse de la réglementation n’entraîne pas l’ acceptation du modèle d’assurance des dépôts garantie par l’Etat tel qu’il existe aux Etats-Unis aujourd’hui.Professors Macey and Miller explore the relationship between deposit insurance and the mismatch in the term structure of commercial banks’ assets and liabilities. After criticizing the traditional regulatory hypothesis, which posits that banks have incentives to fund long-term assets with short-term liabilities because government-sponsored deposit insurance enhances bank credit and subsidizes short-term liabilities, they use public choice theory to argue that a modified version of the regulatory hypothesis is the best explanation for the mismatch in the term structure of banks’ assets and liabilities. Finally, they argue that embracing the regulatory hypothesis does not imply acceptance of the government-sponsored deposit insurance scheme as it exists in the U.S. today. (shrink)

Geoffrey Lloyd engages in a wide-ranging exploration of what we can learn from the study of ancient civilisations that is relevant to fundamental problems, both intellectual and moral, that we still face today. How far is it possible to arrive at an understanding of alien systems of belief? Is it possible to talk meaningfully of 'science' and of its various constituent disciplines, 'astronomy', 'geography', 'anatomy', and so on, in the ancient world? Are logic and its laws universal? Is there (...) one ontology - a single world - to which all attempts at understanding must be considered to be directed? When we encounter apparently very different views of reality, how far can that be put down to a difference in conceptions of what needs explaining, or of what counts as an explanation, or to different preferred modes of reasoning or styles of inquiry? Do the notions of truth and belief represent reliable cross-cultural universals? In another area, what can ancient history teach us about today's social and political problems? Are the discourses of human nature and of human rights universally applicable? What political institutions do we need to help secure equity and justice within nation states and between them? Lloyd sets out to answer all these questions, and to convince us that the science and culture of ancient Greece and China provide precious resources to advance modern debates. (shrink)

This collection brings together leading anthropologists, historians, philosophers, and artificial-intelligence researchers to discuss the sciences and mathematics used in various Eastern, Western, and Indigenous societies, both ancient and contemporary. The authors analyze prevailing assumptions about these societies and propose more faithful, sensitive analyses of their ontological views about reality--a step toward mutual understanding and translatability across cultures and research fields. Science in the Forest, Science in the Past is a pioneering interdisciplinary exploration that will challenge the way readers interested in (...) sciences, mathematics, humanities, social research, computer sciences, and education think about deeply held notions of what constitutes reality, how it is apprehended, and how to investigate it.
