Jason-1/Jason-2 metocean comparisons and monitoring
No full textThe initial tandem phase of the Jason-2 mission is important for the calibration of the entire altimetric system, not just the records of sea surface height. However, as well as allowing a bulk comparison of metocean parameters such as wave height and backscatter strength (used to infer wind speed), it affords a more detailed opportunity to understand the artefacts within each instrument. The wave height comparison shows no bias between the instruments, with the mismatch error of consecutive points independent of one another. The backscatter difference is not a simple offset, but has a trend with weak non-linear variations. The technique for backscatter monitoring using Ku-/C-band differences is validated during the tandem phase, and extended to show ~59-day oscillations throughout the Jason-1 mission. This effect, which is predominantly in the C-band, is related to changing solar exposure, due to the fraction of orbit in eclipse varying as the orbit precesses. Such anomalies were partially present in TOPEX-B data, but are not noticeable for Jason-2. It is recommended that all TOPEX, Jason-1 and Jason-2 data be transformed to a consistent scale, allowing for the bias and trend terms in the offsets between instruments, and correcting for any long-period drifts in individual calibration; this will enable a single wind speed algorithm to be applied to the combined satellite data
On time series clustering with k-means
No full textThere is a long history of research into time series clustering using distance-based partitional clustering. Many of the most popular algorithms adapt k-means (also known as Lloyd's algorithm) to exploit time dependencies in the data by specifying a time series distance function. However, these algorithms are often presented with k-means configured in various ways, altering key parameters such as the initialisation strategy. This variability makes it difficult to compare studies because k-means is known to be highly sensitive to its configuration. To address this, we propose a standard Lloyd's-based model for TSCL that adopts an end-to-end approach, incorporating a specialised distance function not only in the assignment step but also in the initialisation and stopping criteria. By doing so, we create a unified structure for comparing seven popular Lloyd's-based TSCL algorithms. This common framework enables us to more easily attribute differences in clustering performance to the distance function itself, rather than variations in the k-means configuration

Jason vs GIJOE
No full textThesis (Master's)--University of Washington, 2019Jason vs GI JOE is partly an exercise in autobiography, an experiment in relational aesthetics, and an interdisciplinary artist project at the intersection of comic books, creative writing and performance art. This comic book, Jason vs. GIJOE, is a postmodern double erasure, based on the comic book GIJOE: Cobra II (Issue 1). The original pictures from the comic book have been removed, and replaced by a series of short narratives, describing autobiographical events from the life of the author: me, Jason. Speech bubbles from the original have been left to comment back over top of the stories, obscuring meaning but creating moments of unplanned dialogue. The comic is a readymade, twice erased: once to replace the drawings of the initial comic, and again when using the original dialogue bubbles to speak back to the narrative
Oral history interview with Jason Poudrier
No full textJason Poudrier, author, discusses growing up in a military family and living in Alaska, North Dakota, Oregon, and finally Oklahoma. He describes what it was like enlisting in the Army after high school in 2001 and how his military service affected him. A recipient of the Purple Heart, he shares his experiences getting injured by shrapnel in Iraq. He later talks about how he uses poetry and writing to cope with his memories of war, and how he hopes to help others do the same.The Deep Roots: Oklahoma Authors Collection is a series of interviews with authors who discuss their lives, work, and creative processes

The people behind the papers – Jason Ko and Daniel Lobo
No full textPlanarians grow when they are fed and shrink during periods of starvation. However, it is unclear how they maintain appropriate body proportions as their size changes. A new paper in Development investigates the differences between growth and shrinkage dynamics and builds a mathematical model to explore the mechanisms underpinning these two processes. To learn more about the story behind the paper, we caught up with first author, Jason Ko, and corresponding author, Daniel Lobo, Associate Professor at the University of Maryland.https://doi.org/10.1242/dev.20298
“The Support Continuum” Exploring how support workers understand their role in supporting adults with learning disabilities to use the internet for personal and sexual relationships Jason Lines
No full textWith internet use prominent in daily life, research investigating how adults with learning disabilities are accessing and using the internet is increasingly relevant. Three papers are presented in this thesis which aimed to provide additional understanding about this research topic.
The first paper outlines a review of the literature regarding what factors influence how adults with intellectual disabilities access and use the internet. The existing literature suggests a shift in the technology used to access the internet, from computers to smartphones. It also shows a shift in the purpose of internet use, from only using the internet for emails, to multi-platform usage, mainly social media. Significantly, it highlighted how important it is for some adults with learning disabilities to have access to support to assist with using the internet; in addition, the perceptions of those supporting impacted on how much support a person would receive.
The second paper details the empirical research that was undertaken in response to findings from the literature review. Eight support workers took part in this qualitative study which looked at how support workers understand their role supporting adults with learning disabilities to use the internet for personal and sexual relationships. Interviews were transcribed and analysed using thematic analysis. The themes of ‘Social and Organisational dilemmas’ with subthemes ‘Role and Moral positioning’, ‘Expectations of Support’ and ‘Protected and Reflective space; ‘Policy dilemmas’ and ‘Power and position’ were found and discussed. This research highlighted the current gap in training and guidance available for support workers regarding supporting people to use the internet for personal and sexual relationships – suggesting more must be done to develop these training opportunities.
The final paper is an executive summary which condenses the empirical research and presents it in a format accessible to adults with learning disabilities, support workers, and organisations employing support workers
Ep. #085 - Jason W. Moore
No full textThis recording and transcript form part of a collection of podcasts conducted by the Cultures of Energy at Rice University. Cultures of Energy brings writers, artists and scholars together to talk, think and feel their way into the Anthropocene. We cover serious issues like climate change, species extinction and energy transition. But we also try to confront seemingly huge and insurmountable problems with insight, creativity and laughter.Cymene and Dominic talk capital and Vanilla Isis and then (11:21) we welcome to the podcast the one and only Jason W. Moore from Binghamton University, author of Capitalism in the Web of Life (Verso, 2015) and Anthropocene or Capitalocene? (PM Press, 2016). We chat with Jason about his most recent work, co-authored with Raj Patel, A History of the World in Seven Cheap Things (U California Press, 2017), forthcoming this October. We talk about why he wanted to write a book for a broader audience, the problems with the “anthropocene” concept in the human sciences, how “capitalocene” can improve our thinking about world history, and how we can avoid vulgar materialism in critical environmental research and activism today. We cover the role that states and agriculture have played in shaping modern capitalism and Jason calls for a seriously engaged pluralism to tackle the urgent challenges of our era. We discuss the cheapening or thingification of life, capitalism as a gravitational field, the importance of frontiers, the violence of the Great Domestication, and why if green energy remains in the mode of “cheap fuel” nothing will change about capitalist accumulation. Jason explains why racial and gender domination are so often lacunae in critiques of petromodernity. Finally we ruminate on how to unmake the capitalist world-ecology and the key principles of the “reparation ecology” that Jason and his colleagues are calling for.
