It is intended to provide a formal record of information exchange that will be accessible to future workers in the region and to agricultural workers who could not attend.Funded through the US Department of Agriculture Cooperative Extension Service
Episodic use: Practices of care in self-tracking
The development of self-tracking technologies has resulted in a burst of research considering how self-tracking practices manifest themselves in everyday life. Based on a 5-month-long photo elicitation study of Danish self-trackers, we argue that no matter how committed people might be to tracking their activities, their use of self-tracking technologies can be best described as episodic rather than continuous. Using Annemarie Mol’s theoretical framework for understanding care practices as a lens, we show how episodic use can be interpreted through the logic of care. By using self-tracking devices episodically, users employ strategies of care in a way that can be productive and useful. These strategies often come in conflict with the logics of choice that underlie the design of many self-tracking technologies. We argue that this has consequences for the way self-tracking devices need to be imagined, designed, and introduced as part of workplace and insurance-type tracking programs
Interrogating Biosensing in Everyday Life
This workshop seeks to expand our understanding and imaginations regarding the possible roles biosensors (sensors measuring humans) can-and should-play in everyday life. By applying a critical lens to issues of interpretation, representation, and experience around biosensing and biosensors, we aim to shape research agendas within DIS, and generate new recommendations for designers working with biosensors or their data
DEVELOPMENT AND DISTRIBUTION OF INNOVATION FORMS OF SOCIAL CAPITAL ACCUMULATION IN UKRAINE
In the article author defines the essence of social capital and basic theoretical approaches to its understanding. The possibility of diversification and dissemination of innovative forms of social capital accumulation in Ukraine have been proved. It is shown that new forms of manifestation and realization of social capital are emerging, which create new opportunities for socialization of economic relations and formation of new public institutions, which can reverse the development of the economy and the accumulation of social capital. It describes such new forms of social capital as: social entrepreneurship, social Internet networks, freelancing, sharing economy, digitization of economic entities interaction, crowdfunding, crowdsourcing, crowdsourcing, e-government, creation of “digital” communities, specially designed programs and projects, the task of which is to stimulate the activity of citizens and regulate their participation in solving local issues, the formation of corporate social capital, the creation of special social institutions at the global level.In the article author defines the essence of social capital and basic theoretical approaches to its understanding.

INCREASED SPEED AND ENDURANCE OF ADVANCED MULTI-COPTERS THROUGH THE USE OF SIDE THRUSTERS
The Aqua-Quad is a quad-copter designed to float on the ocean, deploying an acoustic sensor at depth, in support of anti-submarine warfare operations, filling the same role as a sonobuoy but with added air mobility. It uses a solar array for power production to gain energy independence, but the array degrades cruise flight performance. The addition of horizontal side-thrusters is explored, with the objective of improving cruise flight efficiency, increasing both speed and range. A subscale quad-copter, representative of Aqua-Quad, is flight tested to prove the feasibility of the side-thruster concept. A secondary controller is designed to autonomously operate the additional motors using ArduPilot’s Lua scripting capability. Final flight tests are conducted on the subscale model configured with a mock solar array. The implementation of side-thrusters effectively regulates the pitch of the vehicle to zero in cruise flight, reducing the pitch angle required at the maximum cruise speed by more than 20 degrees. The vehicle is more efficient when using side-thrusters at high cruise speeds, reducing the required power by about 20% at the maximum tested cruise speed, and higher cruise speeds were possible with the addition of side-thrusters. Lua scripting within ArduPilot proved to be an effective means of implementing an autonomous secondary controller as the vehicle maintained proper control authority during all tests.Distribution Statement A.

Beauty surveillance: the digital self-monitoring cultures of neoliberalism
This paper argues that ‘beauty apps’ are transforming the arena of appearance politics and foregrounds a theoretical architecture for critically understanding them. Informed by a feminist-Foucaultian framework, it argues that beauty apps offer a technology of gender which brings together digital self-monitoring and postfeminist modalities of subjecthood to produce an hitherto unprecedented regulatory gaze upon women that is marked by the intensification, extensification and psychologization of surveillance.
The paper is divided into four sections. First it introduces the literature on digital self-tracking. Secondly it sets out our understanding of neoliberalism and postfeminism. Thirdly it looks at beauty and surveillance, before offering, in the final section, a typology of appearance apps. This is followed by a discussion of the modes of address/authority deployed in these apps – especially what we call ‘surveillant sisterhood’ - and the kinds of entrepreneurial subjectivity they constitute. The paper seeks to make a contribution to feminist surveillance studies and argues that much more detailed research is needed to critically examine beauty apps
Training to self-care: fitness tracking, biopedagogy and the healthy consumer
In this article, we provide an account of Fitbit, a wearable sensor device, using two complementary analytical approaches: auto-ethnography and media analysis. Drawing on the concept of biopedagogy, which describes the processes of learning and training bodies how to live, we focus on how users learn to self-care with wearable technologies through a series of micropractices that involve processes of mediation and the sharing of their own data via social networking. Our discussion is oriented towards four areas of analysis: data subjectivity and sociality; making meaning; time and productivity and brand identity. We articulate how these micropractices of knowing one’s body regulate the contemporary ‘fit’ and healthy subject, and mediate expertise about health, behaviour and data subjectivity
Evaluating lethal toxicant doses for the largest individuals of an invasive vertebrate predator with indeterminate growth
The brown treesnake (Boiga irregularis) was accidentally introduced to Guam and caused severe ecological and economic damages. Acetaminophen is an effective, low-risk oral toxicant for invasive brown treesnakes, and an automated aerial delivery system (ADS) has been developed for landscape-scale toxic bait distribution. A fixed dose of 80 mg of acetaminophen within a tablet inserted into a dead neonatal mouse (DNM) was lethal for all brown treesnakes in previous trials; however, these trials did not include very large individuals which are difficult to acquire for testing. Because most reptiles continue to grow throughout their lifespan, a small number reach much greater than average body sizes. Here, we tested effectiveness of 80 mg acetaminophen DNM baits for unusually large brown treesnakes as they became available. Our results confirmed that an 80 mg dose is lethal for the vast majority of snakes on Guam, but efficacy starts to diminish around 200 g of body mass. We also tested an alternative mouse bait configuration with 160 mg of acetaminophen that could be incorporated into the ADS to improve control of unusually large snakes. The 160 mg dose is expected to be effective for nearly all female snakes; males grow much larger and additional methods will be needed for extraordinarily large individuals. We describe a full dose-response curve for brown treesnakes to acetaminophen tablets and estimate the LD90 at 299 mg/kg and the LD99 at 578 mg/kg. To our knowledge, this is the first published dose-response curve for an invasive vertebrate with indeterminate growth

Self-Tracking, Governmentality, and Nursing and Midwifery Council's (2016) Revalidation Policy
In April 2016 the Nursing and Midwifery Council (NMC) introduced a new revalidation continuous professional development (CPD) policy. This policy states that revalidation is the responsibility of nurses, and although employers are urged to support the revalidation process, the NMC clearly states that employers have no legal requirement to provide either time or funds for the CPD activities of nurses and midwives (NMC, 2014, 2016; Royal College of Nursing, 2016). The aim of this professional development policy is to ensure that nurses and midwives maintain their professional competency and to promote public safety and confidence in nurses and midwives. A closer look at the process of revalidation suggests that several measures have been introduced to ensure that nurses and midwives conform to the CPD policy, and this paper examines the influence of governmentality and neoliberalism on the NMC's self-tracking revalidation policy. It will be recommended that the responsibility for the revalidation process should be shared by nurses, midwives, and their employers, and that time and money should be allocated for the professional development of nurses and midwives
