Based on an ethnographic project in a public high school in a low-income neighborhood in South Los Angeles, this paper argues that access to information and communication technologies cannot be taken as helpful or empowering on its own terms; instead, concerns about justice must be accounted for by the local communities technology is meant to benefit. This paper juxtaposes the concept of technological access with recent work in feminist science and technology studies on infrastructure, maintenance, and ethics. In contrast to (...) popular descriptions of ICTs as emancipatory and transformative, in the setting of an urban school, access produced extensive demands for attention, time, and information. This paper focuses on the labor of a group of student workers, Student Technology Leaders, and how they became responsible for the significant amount of repair and maintenance work involved in keeping hundreds of new computing devices available for use. An expanded process of accounting can more realistically frame issues of justice and its relationship to ICTs. I use a town hall meeting held with these students as an example of a processual vision of justice, one that encourages the beneficiaries of technological access to evaluate costs, benefits, and ethical concerns together.

This paper reports on a two-year, field-based study set in a charter management organization, a not-for-profit educational organization that operates 18 public schools exclusively in the Black and Latinx communities of South and East Los Angeles. At CMO-LAX, the nine-member Data Team pursues the organization's avowed mission of making public schools data-driven, primarily through the aggregation, analysis, and visualization of digital data derived from quotidian educational activities. This paper draws on the theory of racialized organizations to characterize aspects of data-driven (...) management of public education as practiced by CMO-LAX. I explore two examples of how CMO-LAX shapes data to support racial projects: the reconstruction of the figure of chronic truants and the incorporation of this figure in a calculative regime of student accomplishment. Organizational uses of data support a strategy I call productive myopia, a way of pursuing racial projects via seemingly independent, objective quantifications. This strategy allows the organization to claim to mitigate racial projects and, simultaneously, to accommodate them. This paper concludes by arguing for approaches to research and practice that center racial projects, particularly when data-intensive tools and platforms are incorporated into the provision of public goods and services such as education.

Rationale Treatment guidelines recommend a more conservative surgical approach than mastectomy for early stage breast cancer and a stronger emphasis on adjuvant therapy. Registry data at South Australian teaching hospitals have been used to monitor survivals and treatment in relation to these guidelines.Aims and objectives To use registry data to: (1) investigate trends in survival and treatment; and (2) compare treatment with guidelines.Methods Registry data from three teaching hospitals were used to analyse trends in primary courses of treatment of breast (...) cancers during 1977–2003 (n = 4671), using univariate analyses and multiple logistic regression. Disease-specific survivals were analysed using Kaplan–Meier product limit estimates and multivariable Cox proportional hazards regression.Results The 5-year survival was 79.9%, but with a secular increase, reaching 83.6% in 1997–2003. The relative risk of death (95% confidence limits) was 0.74 (0.62, 0.88) for 1997–2003, compared with previous diagnoses, after adjusting for tumour node metastasis stage, grade, age and place of residence. Treatment changes included an increase in conservative surgery (as opposed to mastectomy) from 51.7% in 1977–1990 to 76.8% in 1997–2003 for stage I (P < 0.001) and from 31.1% to 52.2% across these periods for stage II (P < 0.001). Adjuvant radiotherapy also became more common (P < 0.001), with 20.6% of patients receiving this treatment in 1977–1990 compared with 60.7% in 1997–2003. Radiotherapy generally was more prevalent when conservative surgery was provided, although also relatively common in mastectomy patients when tumour diameters exceeded 50 mm or when there were four or more involved nodes. The proportion of patients receiving chemotherapy increased (P < 0.001), from 19.6% in 1977–1990 to 36.9% in 1997–2003, and the proportion having hormone therapy also increased (P < 0.001), from 34.3% to 59.4% between these periods.Conclusions Survivals appear to be increasing and treatment trends are broadly consistent with guideline directions, and the earlier research on which these recommendations were based.

La contribución específica de Hans Kellner a la Nueva Filosofía de la Historia se dirige a dar cuenta del revival de la narrativa a partir de los 80 en términos de un revival de la retórica. Sus relecturas de los textos históricos, metahistóricos, literarios y filosóficos nos invitan a apreciar las estrategias retóricas implicadas en ellos, desplegando aquello que habilitan o imposibilitan decir acerca del pasado. Kellner invita a eludir el planteo fundacionista que se ciñe a la cuestión de la (...) validez epistémica del texto, sin caer por ello en la actitud determinista lingüística que fija las estrategias discursivas en tanto estructuras artificiosas y distorsivas de la realidad. Kellner nos desafía a abandonar la metáfora de la distorsión para caracterizar la relación entre representación y realidad. Si en cuanto filósofxs de la historia nos interesa trazar líneas de continuidad y comunidad en la indagación historiográfica, debemos enfocar en sus fuentes retóricas más que en la evidencia documental o la experiencia del pasado cuyo rasgo manifiesto es la fragmentariedad. Su propuesta promueve que nos focalicemos, por un lado, en las innumerables elecciones tomadas entre las diversas modalidades de conocimiento disponibles. Por el otro, nos advierte de la ansiedad provocada por dicha elección en contra de otras opciones descartadas que podrían habernos hecho pensar las cosas de otra manera.

Gödel's modal ontological argument is the centerpiece of an extensive examination of intensional logic. First, classical type theory is presented semantically, tableau rules for it are introduced, and the Prawitz/Takahashi completeness proof is given. Then modal machinery is added to produce a modified version of Montague/Gallin intensional logic. Finally, various ontological proofs for the existence of God are discussed informally, and the Gödel argument is fully formalized. Parts of the book are mathematical, parts philosophical.

Desiring Whiteness provides a compelling new interpretation of how we understand race. Race is often seen to be a social construction. Nevertheless, we continue to deploy race thinking in our everyday life as a way of telling people apart visually. How do subjects become raced? Is it common sense to read bodies as racially marked? Employing Lacan's theories of the subject and sexual difference, Seshadri-Crooks explores how the discourse of race parallels that of sexual difference in making racial identity (...) a fundamental component of our thinking. Through close readings of literary and film texts, Seshardi-Crooks also investigates whether race is a system of difference equally determined by Whiteness. She argues that it is in relation to Whiteness that systems of racial classification are organized, endowing it with a power to shape human difference. (shrink)

Jan Łukasiewicz’s analysis of Aristotle’s syllogism drew attention to the nature of syllogisms as conditionals rather than premise-conclusion arguments. His further idea that syllogisms should be understood as theorems of an axiom system seems a step too far for many logicians. But there is evidence to suggest that Aristotle’s syllogism was to regularise some of the steps made in ‘dialogue games.’ This way of seeing the syllogism is explored in the framework of modern formal dialogue systems. A modern formal syllogistic (...) game, DLSyll, is set out and analysed in use. (shrink)

Materialist metaphysicians want to side with physics, but not to take sides within physics.If we took literally the claim of a materialist that his position is simply belief in the claim that all is matter, as currently conceived, we would be faced with an insoluble mystery. For how would such a materialist know how to retrench when his favorite scientific hypotheses fail? How did the 18th century materialist know that gravity, or forces in general, were material? How did they know (...) in the 19th century that the electromagnetic field was material, and persisted in this conviction after the aether had been sent packing?The doctrine of physicalism casts a long shadow in contemporary philosophy, configuring all kinds of philosophical issues and projects. Unsurprisingly, its proponents argue that physicalism has all the obvious features necessary for a scientific hypothesis to be in what we will call ‘good standing,’ i.e. being worthy of serious scientific investigation. In fact, many claim much more, arguing that physicalism is a well-confirmed hypothesis and possibly amongst the best of our theories. But, as our second opening passage makes clear, a persistent worry has been that physicalism, or ‘materialism’ as van Fraassen terms it, is an edifice built on sand. For many philosophers question whether the ‘physical’ can be specified at all, or at least in a manner that will produce a physicalism that would be in good standing. (shrink)

INTRODUCTION TO LOGIC is a combined text and workbook for students beginning their study of logic. The workbook style allows students to proceed at their own pace, checking their progress in the end-of-chapter exercises. The text covers propositional logic and predicate logic with identity, the focus being on arguments. The methods of proof are truth-tables and truth-trees in the style of Jeffrey. This text is suitable for students of philosophy, computer science, mathematics and science in general.

She has always existed and is more than a citizen of multiverses,‭ ‬most likely the ground of all.‭ ‬In the West she was introduced around C.570‭ ‬and since then many individuals have searched for her,‭ ‬tried to become familiar with her and created all sorts of,‭ ‬frequently ridiculous,‭ ‬things in her name. Once someone has a passion for her it cannot be extinguished but increases.‭ ‬Objectively this need for her is referred to as‭ ‘‬love of wisdom‭’‬,‭ ‬the need for wisdom,‭ (...) ‬while personally it is a need of some individuals. -/- This passion and need has become institutionalized and it has developed a discourse and became a socio-cultural practice of its own.‭ ‬Fairly recently it has even become a discipline at,‭ ‬mostly higher,‭ ‬institutions of learning.‭ ‬Previously those searching for and attempting to interact with her came from many walks of life and all kinds of professions,‭ ‬while in the last century or so many people began to live off her as they are remunerated for talking about,‭ ‬about the history of searching for and investigating her and saying all sorts of things about her. -/- Many things are done in her name and all sorts of neologisms are fabricated to label them,‭ ‬such as analytic,‭ ‬continental,‭ ‬idealism,‭ ‬rationalism,‭ ‬empiricism,‭ ‬and all these labels are again specified and specified ad infinitum with terms such as materialism,‭ ‬physicalism,‭ ‬weak naturalism,‭ ‬speculative and new realism,‭ ‬etc. -/- Individuals from many other disciplines and areas of life,‭ ‬such as sociology,‭ ‬the arts,‭ ‬humanities,‭ ‬cognitive sciences,‭ ‬sport,‭ ‬etc got on the bandwagon so that we now have a philosophy or love of wisdom,‭ ‬epistemologies,‭ ‬ontologies etc of everything under the sun.‭ ‬Even if you were to write some theses or do some study you will stipulate your epistemology,‭ ‬ontology,‭ ‬methodology,‭ ‬etc.‭ ‬Just as those who live off philosophy become involved in every area of humanity and all its socio-cultural practices produce so-called peer reviewed publications,‭ ‬articles,‭ ‬essays and books on philosophy of art,‭ ‬sport,‭ ‬humanities,‭ ‬cognitive sciences,‭ ‬religion,‭ ‬gods,‭ ‬sex,‭ ‬rock‭ ‘‬n roll,‭ ‬language,‭ ‬words,‭ ‬ideas,‭ ‬how words and ideas and concepts do their thing,‭ ‬etc,‭ ‬etc.‭ -/- The way these subject-matter are treated will usually consists of some form of reasoning,‭ ‬the use of arguments or argumentation and some kind of logic and a process that resembles the features,‭ ‬steps,‭ ‬stages and processes of theorizing,‭ ‬the construction and development of models,‭ ‬short term,‭ ‬medium or large theories.‭ ‬The latter is often presented in the form of entire‭ ‘‬metaphysical‭’ ‬and speculative systems such as those of Plato,‭ ‬Aristotle,‭ ‬Kant,‭ ‬Hegel,‭ ‬Marx,‭ ‬Husserl,‭ ‬Habermas et al.‭ ‬While Socrates and to some extent the later Wittgenstein attempted to be more authentic to the original principles of trying to follow and developed the ideal of identifying,‭ ‬capturing by verbal interaction‭ (‬be it discourse,‭ ‬or dialogue‭) ‬and becoming one‭ (‬like mystics of all religions who are passionate about‭ ‘‬the one‭’‬,‭ ‬the Beloved,‭ ‬the one Real Self,‭ ‬etc and attempt to become one,‭ ‬united with or‭ ‘‬oned‭’ ‬with their object or subject of desire‭) ‬with Sophos‭ – ‬by exploring and investigating or applying and executing practical use of language,‭ ‬and thereby to uncover and capture her. -/- The effects of the institutionalization of the discipline are far-reaching and the professionalization of the role of philosopher as a‭ ‘‬profession‭’‬,‭ ‬an employee of an institution and a representative of the status quo are discussed in a number of articles being cited. -/- The methods of the philosophical discourse vary,‭ ‬first of all between the so-called Continental and Anglophone Analytic philosophies,‭ ‬its movements,‭ ‬schools and institutions,‭ ‬such as research universities,‭ ‬journals,‭ ‬communities and book publishers.‭ ‬It seems as if increasingly philosophizing employs some of the stages and steps of the processes of theorizing.‭ ‬Other aspects of her methods are heuristic devices,‭ ‬the use of metaphors and analogies,‭ ‬philosophical logic,‭ ‬informal and other types of logic,‭ ‬arguments and argumentation.‭ ‬This involves the creation of fallacies in thinking and reasoning and the causing of all sorts of fallacies or crooked thinking. -/- The nature and changes of philosophical subject-matter are discussed as the socio-cultural practice lost most of its traditional‭ ‘‬objects‭’ ‬with the social and cultural differentiation of other,‭ ‬specialized disciplines.‭ ‬In turn the discourse attempts to fabricate other subject-matter,‭ ‬for example the development of so-called Experimental Philosophy,‭ ‬inter-disciplinary studies such as cognitive sciences and philosophies or meta-level explorations of and speculations about other disciplines,‭ ‬professions and domains‭ (‬for example normative,‭ ‬instrumental and subjective aesthetic‭ – ‬this the terminology and distinctions according to the working class obsessive Critical Theory of the so-called Frankfurt Schule.‭ ‬One always wonders what degree of personal experience their educated,‭ ‬middle class academics have of‭ ‘‬the working class‭’‬,‭ ‬whatever that is meant to be‭?)) ‬of human activity.‭ ‬Such as philosophy of medicine,‭ ‬sport,‭ ‬art,‭ ‬religion,‭ ‬just name it and it is bound to exist.‭ -/- Another‭ ‘‬extension‭’ ‬of or interest in‭ ‘‬philosophy‭’ ‬is that of certain individuals,‭ ‬schools or movements in other disciplines,‭ ‬for example social‭ ‘‬sciences‭’ ‬such as sociology and supporters of the above mentioned‭ ‘‬Schule‭’‬.‭ ‬They frequently use philosophical words such as ontology,‭ ‬epistemology,‭ ‬multi-dimensional,‭ ‬many-levels,‭ ‬contexts assumptions,‭ ‬pre-suppositions,‭ ‬immanent,‭ ‬transcendent,‭ ‬etc.‭ ‬Is this intended to be an extension of philosophy and the doing of philosophizing or merely cognitive bias of the form‭ ‘‬authority bias‭’‬.‭ ‬In this case the authority being‭ ‘‬the discipline of philosophy‭’‬,‭ ‬as well as the‭ ’‬use of the word philosophy‭ ‬and terms from the philosophical discourse‭’‬.‭.

One of the questions that Heidegger presents in his paper, ‘Plato’s Doctrine on Truth’, is the distortion as he sees it of paideia—that is the loss of the essential elements in education. This loss is characterised according to Heidegger, by a misconception of Plato’s concept of teaching and learning. By undertaking an historical examination, Heidegger provides a means to rectify this loss. With reference to past, present and future philosophical perspectives of teaching and learning as particular spaces, an attempt is (...) made in this paper to examine Heidegger’s reading of paideia within the context of online learning. This, for many contemporary writers on education, is an encounter with new literacies, new knowledge and the adoption of an online environment that challenges the hegemonic order of the institution as the purveyors of knowledge. Teachers within this new environment are, however still constituted as experts and their knowledge is seen as ultimately inviolate. Heidegger in his re-interpretation of Plato sees the teacher as leading the students to where they might make themselves intelligible within the space of their being. This alignment forms an acceptance and a challenge to the metaphysical concepts of uniformity of being and place that limits the potential of knowledge as something that is fixed and complete. The experience of the social web or Web 2.0 has seen a shift in learning premised upon dialogue, exchange and constantly shifting horizons. Within this context, the teacher is recast as a craftsman, creating learning opportunity within dialogic exchange. The heightened sense of involvement that is revealed in this context lays the ground for a future visioning of education where emergence is seen as essential, unlike a re-working of authorisation to learn that inhibits student and teacher alike in new attempts at revitalising education.

"Crook has an extensive range of interests and writes with authority on the whole sociobiological spectrum. He discusses the behavior of insects, birds, primates, and so forth, with impressive thoroughness and detail. He... introduces an equally expert and apparently firsthand discussion of Eastern philosophy, especially Zen Buddhism. His purpose is to emphasize the duality, or perhaps multiplicity, of consciousness, and the importance of society's more objective facets. A scholarly work complete with excellent bibliographies, index, and references." --Choice.

Traditional epistemology has had an overriding emphasis since Descartes upon knowing, certainty, and truth, said to be obtained through cogitation. An alternative epistemology would emphasize cognitive meaning, ambiguity, and meaninglessness within a presumptive scheme of semantiks, in contrast to the gnostic Cartesian model. Thereby cognition becomes naturalized and intelligible within the framework of biological evolution, in which species-characteristic forms of intelligence may be seen to unfold through phylogeny. Both scientific advance and pedestrian reasoning may be fruitfully interpreted by this novel (...) focus upon cognitive meaning devoid of any epistemic function professedly providing psychological or objective “certainty.” Objective rationality as a whole may be seen to emerge solely from the operations of understanding itself within individual and cultural contexts. Suggestions are given as to the structure and dynamics of comprehension that generate species-characteristic forms of cognitive meaning. (shrink)

In this paper we compare central elements of Dialogue Logic and Belief Revision theory. Dialogue Logic of the Hamblin/Mackenzie style, or Formal Dialectic, contains three main features. First, there is a rule governed interaction between dialogue participants—the minimal case being two participants. Second, each participant has a commitment store which changes as the dialogue progresses. Third, the changes in the commitment store are governed by rules for additions and withdrawals of material. Withdrawal of material is one major source of difficulty (...) in proposing rules for commitment store change. The classic Belief Revision theory is the AGM theory. AGM theory is a theory about ideal rational believers who change their sets of beliefs by either expansion or contraction. Contraction is a major source of difficulty in belief revision theory. We claim that the commitment stores of dialogue logic include, in a sense, the belief sets of belief revision theory. Further, withdrawal and contraction are essentially the same process. We consider various kinds of withdrawal and contraction, and show how approaches to these processes illuminate certain of the formal fallacies. (shrink)
