Perceptually smooth timbral guides by state-space analysis of phase-vocoder parameters

Sculptor is a phase-vocoder-based package of programs that allows users to explore timbral manipulation of sound in real time. It is the product of a research program seeking ultimately to perform gestural capture by analysis of the sound a performer makes using a conventional instrument. Since the phase-vocoder output is of high dimensionality — typically more than 1,000 channels per analysis frame—mapping phase-vocoder output to appropriate input parameters for a synthesizer is only feasible in theory

Antarctic bedrock topography uncertainty and ice sheet stability

All Rights Reserved. Antarctic bedrock elevation estimates have uncertainties exceeding 1km in certain regions. Bedrock elevation, particularly where the bedrock is below sea level and bordering the ocean, can have a large impact on ice sheet stability. We investigate how present-day bedrock elevation uncertainty affects ice sheet model simulations for a generic past warm period based on the mid-Pliocene, although these uncertainties are also relevant to present-day and future ice sheet stability. We perform an ensemble of simulations with random topographic noise added with various length scales and with amplitudes tuned to the uncertainty of the Bedmap2 data set. Total Antarctic ice sheet retreat in these simulations varies between 12.6 and 17.9m equivalent sea level rise after 3kyrs of warm climate forcing. This study highlights the sensitivity of ice sheet models to existing uncertainties in bedrock elevation and the ongoing need for new data acquisition. Key Points Quantify how Antarctic bed elevation uncertainty affects ice sheet simulations Simulate retreat of the Antarctic ice sheet for a warm Pliocene climate Identify key areas for future improvements to bed elevation data

Meaningful occupation as a fundamental principle of health and citizenship

Introduction : Occupational therapists are concerned with fostering abilities and opportunities towards meaningful participation. This aim is conceived in health terms, but implies that health is connected to enacting citizenship, since participation goals are social, transactional and depend on interaction and reciprocal exchange. Objectives: To present a critical discussion of the significance of occupation for health and transformative citizenship. Approach Restriction in participation is also a restriction of citizenship. Practice-based vignettes will serve as examples of how dis-citizenship is generated through marginalisation with negative impacts on health outcomes. Secondly, we will frame exercising citizenship as social participation. This approach of participatory citizenship brings forth the potential of social transformation both individually and collectively based on new collective understandings and mutual recognition. Practice implications Approaching citizenship and health as interrelated and embodied rather than abstract, takes into account the ways in which social and cultural backgrounds as well as material circumstances affect people's lives as citizens. Health conditions are generated or maintained by social conditions such as poverty and limited access to resources and affected by cultural factors such as difference. The implication of critical occupation-based practise is that it offers a possibility to question and challenge these limitations and create particular spaces of action where in everyday life people negotiate rights and possibilities, belonging and participation. Conclusion Citizenship as an occupational practice of participation has valuable potential as the basis for the understanding of processes of participation and health as for the promotion of social transformation and more inclusive communitie

Does ethnic diversity erode trust? Putnams hunkering down thesis reconsidered

We use a multi-level modelling approach to estimate the effect of ethnic diversity on measures of generalized and strategic trust using data from a new survey in Britain with a sample size approaching 25,000 individuals. In addition to the ethnic diversity of neighbourhoods, we incorporate a range of indicators of the socio-economic characteristics of individuals and the areas in which they live. Our results show no effect of ethnic diversity on generalized trust. There is a statistically significant association between diversity and a measure of strategic trust, but in substantive terms, the effect is trivial and dwarfed by the effects of economic deprivation and the social connectedness of individuals

Reflexiones sobre ocupación, identidades culturales y transformación social

Cuando fui invitado con tanta amabilidad al XVI Congreso Colombiano de Terapia Ocupacional el año pasado en Medellín, una de las impresiones más fuertes de mi corta visita fue el contenido de folclor cultural, a través del uso de la música y la danza, en muchas de las presentaciones. Esto hizo que fuera una experiencia muy diferente a la de otros congresos a los que he asistido. El significado de las culturas parecía ser una parte integral de la práctica profesional, por ejemplo con comunidades indígenas y con poblaciones en áreas rurales, así como del posicionamiento de la Terapia Ocupacional dentro de la historia colombiana reciente. Lo que resultó muy distinto para mí como británico fue que las manifestaciones de música y danza eran algo que todo el mundo parecía conocer y en lo cual todos podían participar. La fortaleza de este aspecto cultural compartido, el cual refleja algunos de los aspectos de la variedad de tradiciones en Colombia, fue cautivador. Esto me llevó a reflexionar sobre el enfoque comunitario de la ocupación humana con propósito, entendido como el hacer colectivo que constituye la cultura. Este artículo de reflexión discute algunos aspectos de la ocupación y la cultura como producto del hacer colectivo para el propósito humano de la comunidad. Se consideran la ocupación y la cultura en oposición a los antecedentes de uso de la ocupación para la salud, y como fundamento de las prácticas socialmente transformadoras. Se esbozan algunos aspectos de la cultura popular de Colombia y el Reino Unido, y algunas razones por las cuales los profesionales deben ser cuidadosos en respetar su integridad, así como su capacidad para la innovación, la adaptación y el cambio como cultura viva

In vivo quantification of peroxisome tethering to chloroplasts in tobacco epidermal cells using optical tweezers

Open access articlePeroxisomes are highly motile organelles that display a range of motions within a short time frame. In static snapshots they can be juxtaposed to chloroplasts which has led to the hypothesis that they are physically interacting. Here, using optical tweezers we have tested the dynamic physical interaction in vivo. Using near-infrared optical tweezers, combined with TIRF microscopy, we were able to trap peroxisomes and approximate the forces involved in chloroplast association in vivo, and observed weaker tethering to additional unknown structures within the cell. We show that chloroplasts and peroxisomes are physically tethered through peroxules, a poorly described structure in plant cells. We suggest peroxules have a novel role in maintaining peroxisome-organelle interactions in the dynamic environment. This could be important for fatty acid mobilisation and photorespiration through interaction with oil bodies and chloroplasts, highlighting a fundamentally important role for organelle interactions for essential biochemistry and physiological processes.Biotechnology and Biological Sciences Research Council (BBSRC)Science and Technology Facilities Council (STFC)Wellcome Trust - Institutional Strategic Support AwardLeverhulme Trus

Educational materials on citizenship from an occupational perspective

Sarah Kantartzis - ORCID: 0000-0001-5191-015X https://orcid.org/0000-0001-5191-015XThis booklet presents educational materials for teachers or educators and students of occupational therapy in higher education programmes. The materials can also be applied in interprofessional programmes, to enable an occupation-based approach to citizenship to be negotiated in the inter-curricula context. In addition, they will be useful for the continuing professional development of people working in health and social fields and in community development programmes. The general aim is to facilitate and highlight addressing issues of citizenship in the contemporary education of occupational therapists. The purpose is to bring the co-creation of knowledge, skills and values of participatory citizenship together with strategic political, cultural and critical thinking into education, particularly at the Diploma/Bachelor or pre-registration levels. The booklet is written in three sections, which present: Section 1: An introduction to the concept of citizenship and particularly of participatory citizenship (Chapter 2). Section 2: A discussion of competences and learning outcomes, as well as of the theoretical approaches that underpin these educational materials (Chapters 3 and 4). Section 3: A range of educational materials, enabling flexible, contextualised, approaches, for the exploration, understanding and development of knowledge regarding participatory citizenship (Chapter 5).This booklet has been published with the support from a grant of the European Network of Occupational Therapy in Higher Education (ENOTHE) for the Project: “Citizenship II”.https://doi.org/10.17979/spudc.9788497498142pubpu
