C. S. Peirce and the Square Root of Minus One: Quaternions and a Complex Approach to Classes of Signs and Categorical Degeneration

The beginning for C. S. Peirce was the reduction of the traditional categories in a list composed of a fundamental triad: quality, respect and representation. Thus, these three would be named as Firstness, Secondness and Thirdness, as well given the ability to degeneration. Here we show how this degeneration categorical is related to mathematical revolution which Peirce family, especially his father Benjamin Peirce, took part: the advent of quaternions by William Rowan Hamilton, a number system that extends the complex numbers, i.e. those numbers which consists of an imaginary unit built by the square root of minus one. This is a debate that can, and should, have contributions that take into account the role that mathematical analysis and linear algebra had in C. S. Peirce’s past

Dorothy Day’s Pursuit of Public Peace through Word and Action

A co-founder of the Catholic Worker Movement, its newspaper, and hospitality houses, the writer Dorothy Day promoted public peace nationally and internationally as a journalist, an organizer of public protests, and a builder of associational communities. Drawing upon Hannah Arendt’s conceptions of the role of speech and action in creating the public realm, this paper focuses on several of Day’s most controversial public positions: her leadership of non-cooperation against Civil Defense drills intended to prepare New York City residents to survive a nuclear war; her urging of Catholics to find common cause with the Cuban revolutionary government; and her support for interracial farming communities in the Southern United States. As Arendt asserts about Rahel Varnhagen’s salon in Berlin, by being public meeting spaces hosted in private houses, Catholic Worker communities fostered egalitarian rather than “agonal” politics. Like Gandhi’s newspapers and ashrams as well as “Occupy” communities such as Zuccotti Park, Day’s newspaper was a center for incubating and implementing social reform. The Catholic Worker provided a place where writers could question the official rhetoric of such conflicts as World War II and the Cold War, put forward different interpretations of unfolding events, and chart possible alternatives to establishment agendas

Allegories of Temporal Experience: The Late Work of Frederic Leighton

The late paintings of Victorian artist Frederic Leighton generally embody an abstract idea or concept instead of a specific story or moral. Many of these images express humanity\u27s experience of the passage of time as it relates to life, death, and rebirth. Leighton\u27s paintings The Garden of the Hesperides, Lachrymae, and Flaming June represent allegories of timelessness, death, and regeneration, respectively

An interprofessional nurse-led mental health promotion intervention for older home care clients with depressive symptoms.

BackgroundDepressive symptoms in older home care clients are common but poorly recognized and treated, resulting in adverse health outcomes, premature institutionalization, and costly use of health services. The objectives of this study were to examine the feasibility and acceptability of a new six-month interprofessional (IP) nurse-led mental health promotion intervention, and to explore its effects on reducing depressive symptoms in older home care clients (≥ 70 years) using personal support services.MethodsA prospective one-group pre-test/post-test study design was used. The intervention was a six-month evidence-based depression care management strategy led by a registered nurse that used an IP approach. Of 142 eligible consenting participants, 98 (69%) completed the six-month and 87 (61%) completed the one-year follow-up. Outcomes included depressive symptoms, anxiety, health-related quality of life (HRQoL), and the costs of use of all types of health services at baseline and six-month and one-year follow-up. An interpretive descriptive design was used to explore clients', nurses', and personal support workers' perceptions about the intervention's appropriateness, benefits, and barriers and facilitators to implementation.ResultsOf the 142 participants, 56% had clinically significant depressive symptoms, with 38% having moderate to severe symptoms. The intervention was feasible and acceptable to older home care clients with depressive symptoms. It was effective in reducing depressive symptoms and improving HRQoL at six-month follow-up, with small additional improvements six months after the intervention. The intervention also reduced anxiety at one year follow-up. Significant reductions were observed in the use of hospitalization, ambulance services, and emergency room visits over the study period.ConclusionsOur findings provide initial evidence for the feasibility, acceptability, and sustained effects of the nurse-led mental health promotion intervention in improving client outcomes, reducing use of expensive health services, and improving clinical practice behaviours of home care providers. Future research should evaluate its efficacy using a randomized clinical trial design, in different settings, with an adequate sample of older home care recipients with depressive symptoms.Trial registrationClinicaltrials.gov identifier: NCT01407926

Attitudes and preferences about the Stepped-Care Model of depression treatment in oncology: a pilot study

The current pilot study examines the feasibility of conducting a full-scale study that utilizes a survey-based cross-sectional methodological design. The purpose was to systematically explore the attitudes about the Stepped-Care (SC) Model of depression treatment, specific treatment preferences for depression, and client characteristics of a sample of women diagnosed with breast cancer. A total of 26 women were recruited from a breast cancer clinic located in the Northeastern United States. Preliminary results indicated that participants on average rated treatments within the SC Model as acceptable, tended to prefer step three (e.g. psychotherapy, medication, or a combined approach) or step two (e.g. self-help, or psychoeducation) of the SC Model, and tended to express strong to very strong preferences. Additionally, correlational analysis indicated moderate to strong significant relationships between the severity of depressive symptoms, quantified resilience, and emotional and cognitive perceptions of the illness. The current pilot study\u27s preliminary results are to be interpreted with caution and guide future directions in conducting a full-scale study with a larger and more representative sample

How to write a history of philosophy? The case of eighteenth-century Britain

This paper raises the question of how a history of the philosophy of eighteenth-century Britain should be written. First, it describes the usual answer to this question, which divides the period into what happened before Hume, then Hume, then responses to Hume. It notes that this answer does not correspond well with how the period saw itself. It then considers how ‘philosophy’ is defined in Britain in the eighteenth century, taking into account dictionary definitions, book titles, and university syllabi. Obvious differences between eighteenth-century and twenty-first-century philosophy are explored, including the idea that ‘natural philosophy’ is as much part of philosophy as moral philosophy, metaphysics, and logic, and the difficulty of making a distinction between philosophy and what we now call psychology. In the final section of the paper some difficulties are raised regarding the hypothesis that ‘enlightenment’ might provide an organizing concept for a more historically sensitive account of eighteenth-century British philosophy.Publisher PDFPeer reviewe
