Reflections on Building DartDraw: A React + Redux Vector-Based Graphics Editor

In this paper, I discuss some of the design challenges I encountered while contributing to DartDraw, a React-Redux drawing application modeled after MacDraw. The features I worked on include: zoom, pan, grid, ruler, and arrowheads

A compilation of observations from moored current meters and thermographs. Vol. 3. Oregon continental shelf, May-June 1967, April-September 1968

A summary of one phase of a direct observational program conducted in the coastal region off Oregon is presented. The measurements were made primarily on the continental shelf during most of the coastal upwelling season (May and June 1967; April through September 1968). The principal measurements were time series of horizontal current velocity and temperature fields; these observations were made with an array of moored, recording meters. Supplementary measurements of hydrographic variables, wind, atmospheric pressure, and mean sea level were also made

A compilation of observation[s] from moored current meters, thermographs, and wind instrument. Vol. 4. Peru continental shelf March-April 1969

A summary of moored instrument measurements over the continental shelf of Peru is presented. Measurements of variables were made in an upwelling zone between Pisco and San Juan, from 28 March to 9 April, 1969. Time series of temperature and horizontal current and wind velocities were obtained at several depths and locations by an array of moored, recording instruments. Supplementary hydrographic and drogue measurements were also made

Population policies and education: exploring the contradictions of neo-liberal globalisation

The world is increasingly characterised by profound income, health and social inequalities (Appadurai, 2000). In recent decades development initiatives aimed at reducing these inequalities have been situated in a context of increasing globalisation with a dominant neo-liberal economic orthodoxy. This paper argues that neo-liberal globalisation contains inherent contradictions regarding choice and uniformity. This is illustrated in this paper through an exploration of the impact of neo-liberal globalisation on population policies and programmes. The dominant neo-liberal economic ideology that has influenced development over the last few decades has often led to alternative global visions being overlooked. Many current population and development debates are characterised by polarised arguments with strongly opposing aims and views. This raises the challenge of finding alternatives situated in more middle ground that both identify and promote the socially positive elements of neo-liberalism and state intervention, but also to limit their worst excesses within the population field and more broadly. This paper concludes with a discussion outling the positive nature of middle ground and other possible alternatives

Current meter data from the Samoan Passage experiment : world ocean circulation experiment current meter array PCM-11 : September 1992-February 1994

The Samoan Passage experiment was designed to determine the northward transport of abyssal water through the Samoan Passage (l0°S, 170°W). This topographic constriction forms the major connection for deep (>4000 m) interbasin flow between hemispheres in the Pacific (Figure 1). This report presents current meter data from the six subsurface moorings deployed in the Samoan Passage in September 1992 and recovered February 1994. The six subsurface moorings were deployed along a transect in the Samoan Passage (Figure 2). A total of twenty-seven current meters were attached, each measuring horizontal current and temperature, with the upper two meters on each mooring measuring pressure. All instrumentation was recovered. Instrument 5872, the top meter on mooring two experienced an electronic board failure after 5 days and stopped recording data. The pressure sensor on instrument 4412, 2990 m on mooring 1, abruptly changed levels several times, and the temperature record from instrument 5856, 2970 m on mooring six, malfunctioned after 9 months. The compass on instrument 7769 (4900 m on mooring three) failed its post-cruise calibration. It appears that the failure occurred approximately one-fourth of the way through the deployment. Because the data are vector-averages, both speed and direction are suspect. The quality of the remaining records was excellent. The Samoan Passage current meter array contributes to the World Ocean Circulation experiment and is identified by that program as PCM-11

Public Health Impact and Cost-Effectiveness of Hepatitis A Vaccination in the United States: A Disease Transmission Dynamic Modeling Approach

Objective: To assess the population-level impact and costeffectiveness of hepatitis A vaccination programs in the United States. Methods: We developed an age-structured population model of hepatitis A transmission dynamics to evaluate two policies of administering a twodose hepatitis A vaccine to children aged 12 to 18 months: 1) universal routine vaccination as recommended by the Advisory Committee on Immunization Practices in 2006 and 2) Advisory Committee on Immunization Practices's previous regional policy of routine vaccination of children living in states with high hepatitis A incidence. Inputs were obtained from the published literature, public sources, and clinical trial data. The model was fitted to hepatitis A seroprevalence (National Health and Nutrition Examination Survey II and III) and reported incidence from the National Notifiable Diseases Surveillance System (1980)(1981)(1982)(1983)(1984)(1985)(1986)(1987)(1988)(1989)(1990)(1991)(1992)(1993)(1994)(1995). We used a societal perspective and projected costs (in 2013 US $), qualityadjusted life-years, incremental cost-effectiveness ratio, and other outcomes over the period 2006 to 2106. Results: On average, universal routine hepatitis A vaccination prevented 259,776 additional infections, 167,094 outpatient visits, 4781 hospitalizations, and 228 deaths annually. Compared with the regional vaccination policy, universal routine hepatitis A vaccination was cost saving. In scenario analysis, universal vaccination prevented 94,957 infections, 46,179 outpatient visits, 1286 hospitalizations, and 15 deaths annually and had an incremental cost-effectiveness ratio of$21,223/quality-adjusted life-year when herd protection was ignored. Conclusions: Our model predicted that universal childhood hepatitis A vaccination led to significant reductions in hepatitis A mortality and morbidity. Consequently, universal vaccination was cost saving compared with a regional vaccination policy. Herd protection effects of hepatitis A vaccination programs had a significant impact on hepatitis A mortality, morbidity, and cost-effectiveness ratios

Deep western boundary currents in the southwestern Pacific Ocean : WOCE PCM-9 : February 1991-December 1992

This report describes current meter measurements from an experiment to measure the deep western boundary current that carries dense water from the Antarctic to the Pacific Ocean. The field measurements were conducted as part of a joint two year experiment by Oregon State University, Texas A&M University, Woods Hole Oceanographic Institution and the New Zealand Oceanographic Institute. The effective western boundary for deep waters in the South Pacific is located east of New Zealand and consists of the Campbell Plateau, Chatham Rise and the Kermadec and Tonga Ridges. Because there is no substantial source of dense bottom waters in the North Pacific, all the deep and bottom waters of both the North and South Pacific have their origin in the Antarctic, and are carried north in a deep western boundary current (DWBC). Neither the sinking of dense water in a few places near the Antarctic Continent nor the general upwelling of this water throughout the rest of the world ocean are easily measurable; since the DWBC is the sole source of deep inflow for the world's largest ocean, knowledge of its strength and variability is critical to a better understanding of the ventilation and heat balance of the Pacific. No direct measurements had ever been made in the DWBC in the Pacific, and evidence of its width could only be made from hydrographic evidence. It was decided to deploy the U.S. resources along a 1000-km line at 32.5°S extending east from the western boundary (Fig. 1, Table 1). Three nominal depths were instrumented: about 200m above the bottom, 4500m, and 2500m (Fig. 2). The 2500m level was selected because it was anticipated that it is near the top of the DWBC in the west, and should show predominately northward flow in the eastern part of the array. The array was deployed in January and February, 1991 from the RN Rapuhia operated by the New Zealand Oceanographic Institute. It consisted of 20 sub-surface moorings, with a total of 60 current meters. It was recovered in November and December, 1992 by the FN Giljanes. The acoustic releases failed on four of the mooring. Partial instrumentation on three of these were recovered by dragging. Mooring 8 was not recovered. The top instrument on Mooring 14 sunk during recovery. A total of 53 current meters were recovered. The experiment was called MAPKIWI, but nobody remembers why. The MAPKIWI current meter array contributes to the World Ocean Circulation experiment and is identified by that program as PCM-9

Effects of Grassland Management Practices on Ant Functional Groups in Central North America

Tallgrass prairies of central North America have experienced disturbances including fire and grazing for millennia. Little is known about the effects of these disturbances on prairie ants, even though ants are thought to play major roles in ecosystem maintenance. We implemented three management treatments on remnant and restored grassland tracts in the central U.S., and compared the effects of treatment on abundance of ant functional groups. Management treatments were: (1) patch-burn graze—rotational burning of three spatially distinct patches within a fenced tract, and growing-season cattle grazing; (2) graze-and-burn—burning entire tract every 3 years, and growing-season cattle grazing, and (3) burn-only—burning entire tract every 3 years, but no cattle grazing. Ant species were classified into one of four functional groups. Opportunist ants and the dominant ant species, Formica montana, were more abundant in burn-only tracts than tracts managed with either of the grazing treatments. Generalists were more abundant in graze-and-burn tracts than in burn-only tracts. Abundance of F. montana was negatively associated with pre-treatment time since fire, whereas generalist ant abundance was positively associated. F. montanawere more abundant in restored tracts than remnants, whereas the opposite was true for subdominants and opportunists. In summary, abundance of the dominant F. montana increased in response to intense disturbances that were followed by quick recovery of plant biomass. Generalist ant abundance decreased in response to those disturbances, which we attribute to the effects of competitive dominance of F. montana upon the generalists

Heavy genealogy: mapping the currents, contraflows and conflicts of the emergent field of metal studies, 1978-2010

What is metal studies? How can we define and characterize it? How has it emerged as a body of academic enquiry? What are its dominant disciplinary strands, theoretical concepts and preferred methodologies? Which studies have claimed most attention, defined the goals of scholarship, typical research strategies and values? How has the claim for the legitimacy or symbolic value of metal scholarship been achieved (if it has): over time and through gradual acceptance or through conflict and contestation? How can this process of formation, or strategy of legitimation, be mapped, examined and interrogated and which methods of historical, institutional and cultural analysis are best suited to this task? Working with the most complete bibliography to date of published research on heavy metal, music and culture (the MSBD), this article employs Foucault’s archaeological “method” to examine the institutional, cultural and political contexts and conflicts that inform the genealogy of this scholarship. Such analysis reveals a formative, largely negative account of heavy metal to be found in the “sociology of rock”; a large volume of psychology work, examining heavy metal music preference as an indicator of youth risk, deviance and delinquency; sociological work on youth and deviancy critical of the values of this research and its links to social policy and politics; culminating in the work of Weinstein and Walser, who advocate a perspective sympathetic to the values of heavy metal fans themselves. Following Bourdieu, I interpret such symbolic strategies as claims for expertise within the academic field that are high or low in symbolic capital to the extent they can attain disciplinary autonomy. I then go on to examine the most recent strands of research, within cultural studies and ethnomusicology, concerned with the global metal music diaspora, and consider to what extent such work is constitutive of a coherent subfield of metal studies that can be distinguished from earlier work and what the implications of this might be
