Trees and springs as social property: a perspective on degrowth and redistributive democracy from a Brazilian squatter community

Abstract Questions concerning the maldistribution of property and productive resources continue to inform debates about how to bring about societies that are livable, equitable, and ecologically sustainable. In the diverse imaginaries of revolutionary, utopian, socialist, and anti-capitalist politics—together with their adversaries— the notions of "collective" and "private" property have often been conceived as mutually exclusive and exhaustive alternatives. Drawing from several years of ethnographic research with rural squatters in the cacao lands of Bahia, Brazil, the author brings together alternative ways of conceptualizing property that can help overcome this lingering dichotomy and fruitfully inform new political projects. The article examines local practices of property-making through two cases focused on the private ownership and stewardship of natural springs, and the processes whereby squatters convert forest into agroforest. The analysis highlights the ways in which these "private" properties are intersected by "public" interests and "collective" practices, while considering the different kinds of relations that these intersections afford among people and between humans and the non-human environment. Based on these cases, the author suggests that current conversations about "degrowth" may benefit by drawing together frameworks from political ecology, economic anthropology, and property jurisprudence. The presentation concludes by highlighting potential synergies between concerns for degrowth and claims for property democratization.

Cultivating Hope: Struggles for Land, Equality, and Recognition in the Cacao Lands of Southern Bahia, Brazil.

This dissertation traces the historical trajectory of contemporary land rights movements in the cacao lands of Bahia, Brazil. These social movements are examined as one moment in the ongoing, multigenerational struggle to realize the promise of emancipation among descendants of former slaves and other members of the rural poor. The dissertation is based on over three years of ethnographic and ethnohistorical research in several squatter communities in the region, with families that are seeking to build new lives apart from the region’s cacao and rubber plantations. The dissertation examines the relationship between oral narratives and the historically emergent notions of justice and the good that inform these families’ efforts to create meaningful forms of social life. As this research focuses on the transformation of deeply rooted inequalities, the dissertation draws on a mixed methodology that affords greater historical purchase on contemporary social struggles. These methods include participant-observation; analysis of oral histories; household and farm surveys; and research into locally available historical documents. The historical arc of the research ranges from the post-emancipation lifeworld in the region’s hills, where freed slaves and other members of the rural poor had migrated to build new agrarian communities. It continues by exploring experiences of dispossession and a forced return to plantation life, as the world these families had created was destroyed in a series of land grabs that occurred as a new wave of cacao and rubber plantations overtook the region between the 1950s and 1970s. Finally, the dissertation examines a period in the late 1980s and 1990s when these plantations entered a period of decline, opening the door for new squatter and land rights movements that began to occupy and cultivate former plantation lands. These squatters’ orientation toward this long history not only informs their sense of justice in relation to regional elites, but also political struggles that have emerged internal to these social movements where some dimensions of domination and hierarchy threatened to recur. This investigation of these various periods of transgression, protest, and renewal simultaneously traces transformations in people’s sense of self, community, and the value of their land and labor.PhDAnthropologyUniversity of Michigan, Horace H.

Controlling Knowledge and the Role of Engaged Intellectuals

Has there been a major (epistemic) transformation towards more balanced global knowledge production or have inequalities been intensified? How are terms defined or what do we understand by ‘global knowledge production’ or ‘epistemic inequality’? How can we adapt our research topics or methods to shape a more egalitarian (global) kind of knowledge? Can we identify the (conscious) ‘gatekeepers’ of epistemic exclusion; for example, disciplinary conventions, modi operandi of publication and funding schemes, or interiorized ‘colonial’ practices? And if so, what can we do about them at conferences, in the publishing and funding sectors? How can privileged scholars engage in critical self-reflection of their academic practices – both at a theoretical and methodological level but also in everyday practices? By means of addressing these questions in a variety of ways, the aim of the issue is to investigate to what extent, how and why institutional, financial and ideological factors restrain the manoeuvring spaces, and how scholars, artists and civil society institutions can sensitise for, unmask, and resist them

Hospitalizations in patients with atrial fibrillation:an analysis from ROCKET AF

AIMS: The high costs associated with treatment for atrial fibrillation (AF) are primarily due to hospital care, but there are limited data to understand the reasons for and predictors of hospitalization in patients with AF. METHODS AND RESULTS: The ROCKET AF trial compared rivaroxaban with warfarin for stroke prophylaxis in AF. We described the frequency of and reasons for hospitalization during study follow-up and utilized Cox proportional hazards models to assess for baseline characteristics associated with all-cause hospitalization. Of 14 171 patients, 14% were hospitalized at least once. Of 2614 total hospitalizations, 41% were cardiovascular including 4% for AF; of the remaining, 12% were for bleeding. Compared with patients not hospitalized, hospitalized patients were older (74 vs. 72 years), and more frequently had diabetes (46 vs. 39%), prior MI (23 vs. 16%), and paroxysmal AF (19 vs. 17%), but less frequently had prior transient ischaemic attack/stroke (49 vs. 56%). After multivariable adjustment, lung disease [hazard ratio (HR) 1.46, 95% confidence interval (CI) 1.29–1.66], diabetes [1.22, (1.11–1.34)], prior MI [1.27, (1.13–1.42)], and renal dysfunction [HR 1.07 per 5 unit GFR < 65 mL/min, (1.04–1.10)] were associated with increased hospitalization risk. Treatment assignment was not associated with differential rates of hospitalization. CONCLUSION: Nearly 1 in 7 of the moderate-to-high-risk patients with AF enrolled in this trial was hospitalized within 2 years, and both AF and bleeding were rare causes of hospitalization. Further research is needed to determine whether care pathways directed at comorbid conditions among AF patients could reduce the need for and costs associated with hospitalization

Validation of Kepler's Multiple Planet Candidates. III: Light Curve Analysis & Announcement of Hundreds of New Multi-planet Systems

The Kepler mission has discovered over 2500 exoplanet candidates in the first two years of spacecraft data, with approximately 40% of them in candidate multi-planet systems. The high rate of multiplicity combined with the low rate of identified false-positives indicates that the multiplanet systems contain very few false-positive signals due to other systems not gravitationally bound to the target star (Lissauer, J. J., et al., 2012, ApJ 750, 131). False positives in the multi- planet systems are identified and removed, leaving behind a residual population of candidate multi-planet transiting systems expected to have a false-positive rate less than 1%. We present a sample of 340 planetary systems that contain 851 planets that are validated to substantially better than the 99% confidence level; the vast majority of these have not been previously verified as planets. We expect ~2 unidentified false-positives making our sample of planet very reliable. We present fundamental planetary properties of our sample based on a comprehensive analysis of Kepler light curves and ground-based spectroscopy and high-resolution imaging. Since we do not require spectroscopy or high-resolution imaging for validation, some of our derived parameters for a planetary system may be systematically incorrect due to dilution from light due to additional stars in the photometric aperture. None the less, our result nearly doubles the number of verified exoplanets.Comment: 138 pages, 8 Figures, 5 Tables. Accepted for publications in the Astrophysical Journa

Behavioural changes in dairy cows with lameness in an automatic milking system

There is a tendency worldwide for the automation of farms; this has included the introduction of automatic milking systems (AMS) in the dairy industry. Lameness in dairy cows is highly prevalent and painful. These impacts potentially affect not only animal welfare, but also farm economies. Three independent observational studies were carried out to assess the impact of lameness on the behaviour of zero grazed high yielding Holstein cows managed in an AMS. The aim of the first study was to examine the impact of lameness on rumination time, the second study investigated differences between lame and sound dairy cows in total eating time and the third study assessed the impact of lameness on milking behaviour (frequency and time of visits to the AMS). In the first study data from 150 cows were used to analyse rumination (collected using rumination collars) for the 48hr following locomotion scoring. A multilevel linear regression demonstrated that lameness had a small but significant negative association (coefficient: -7.88 (SE: 3.93)) with rumination. In the second study the behaviour of eleven matched lame and sound pairs of cows at the feed face was analysed for 24 hours after locomotion scoring. Each feeding behaviour variable (total duration time, frequency of feeding bouts and length of bouts) was analysed using individual single level regression models. There was a significant negative association between total feeding time and lameness (coefficient: -73.65 (SE: 25.47)) and the frequency of feeding bouts and lameness (-9.93 (2.49)). Finally, the third observational study used 38 matched pairs of lame and sound cows. Data on the number and timings of visits to the AMS were collected for 24 hours after each locomotion score and analysed using a binomial logistic regression model. There was a significant difference in AMS visits between groups; lame animals visiting the robot less frequently than sound cows (median difference 0.50 milking visits; T = 256.0; N = 25; p = 0.01) and lame cows were 0.33 times less likely to visit the AMS between 24:01 and 06:00. Results from these studies reveal that lameness in an AMS affected feeding behaviour, rumination and AMS visits. All of these impacts are likely to have negative consequences for farm profitability, but also implications for the health and welfare of the animals

Characteristics of Kepler Planetary Candidates Based on the First Data Set: The Majority are Found to be Neptune-Size and Smaller

In the spring of 2009, the Kepler Mission commenced high-precision photometry on nearly 156,000 stars to determine the frequency and characteristics of small exoplanets, conduct a guest observer program, and obtain asteroseismic data on a wide variety of stars. On 15 June 2010 the Kepler Mission released data from the first quarter of observations. At the time of this publication, 706 stars from this first data set have exoplanet candidates with sizes from as small as that of the Earth to larger than that of Jupiter. Here we give the identity and characteristics of 306 released stars with planetary candidates. Data for the remaining 400 stars with planetary candidates will be released in February 2011. Over half the candidates on the released list have radii less than half that of Jupiter. The released stars include five possible multi-planet systems. One of these has two Neptune-size (2.3 and 2.5 Earth-radius) candidates with near-resonant periods.Comment: Paper to accompany Kepler's June 15, 2010 data release; submitted to Astrophysical Journal Figures 1,2,& 3 revised.

Planetary Candidates Observed by Kepler, III: Analysis of the First 16 Months of Data

New transiting planet candidates are identified in sixteen months (May 2009 - September 2010) of data from the Kepler spacecraft. Nearly five thousand periodic transit-like signals are vetted against astrophysical and instrumental false positives yielding 1,091 viable new planet candidates, bringing the total count up to over 2,300. Improved vetting metrics are employed, contributing to higher catalog reliability. Most notable is the noise-weighted robust averaging of multi-quarter photo-center offsets derived from difference image analysis which identifies likely background eclipsing binaries. Twenty-two months of photometry are used for the purpose of characterizing each of the new candidates. Ephemerides (transit epoch, T_0, and orbital period, P) are tabulated as well as the products of light curve modeling: reduced radius (Rp/R*), reduced semi-major axis (d/R*), and impact parameter (b). The largest fractional increases are seen for the smallest planet candidates (197% for candidates smaller than 2Re compared to 52% for candidates larger than 2Re) and those at longer orbital periods (123% for candidates outside of 50-day orbits versus 85% for candidates inside of 50-day orbits). The gains are larger than expected from increasing the observing window from thirteen months (Quarter 1-- Quarter 5) to sixteen months (Quarter 1 -- Quarter 6). This demonstrates the benefit of continued development of pipeline analysis software. The fraction of all host stars with multiple candidates has grown from 17% to 20%, and the paucity of short-period giant planets in multiple systems is still evident. The progression toward smaller planets at longer orbital periods with each new catalog release suggests that Earth-size planets in the Habitable Zone are forthcoming if, indeed, such planets are abundant.Comment: Submitted to ApJS.

Clinically Actionable Hypercholesterolemia and Hypertriglyceridemia in Children with Nonalcoholic Fatty Liver Disease

OBJECTIVE: To determine the percentage of children with nonalcoholic fatty liver disease (NAFLD) in whom intervention for low-density lipoprotein cholesterol or triglycerides was indicated based on National Heart, Lung, and Blood Institute guidelines. STUDY DESIGN: This multicenter, longitudinal cohort study included children with NAFLD enrolled in the National Institute of Diabetes and Digestive and Kidney Diseases Nonalcoholic Steatohepatitis Clinical Research Network. Fasting lipid profiles were obtained at diagnosis. Standardized dietary recommendations were provided. After 1 year, lipid profiles were repeated and interpreted according to National Heart, Lung, and Blood Institute Expert Panel on Integrated Guidelines for Cardiovascular Health and Risk Reduction. Main outcomes were meeting criteria for clinically actionable dyslipidemia at baseline, and either achieving lipid goal at follow-up or meeting criteria for ongoing intervention. RESULTS: There were 585 participants, with a mean age of 12.8 years. The prevalence of children warranting intervention for low-density lipoprotein cholesterol at baseline was 14%. After 1 year of recommended dietary changes, 51% achieved goal low-density lipoprotein cholesterol, 27% qualified for enhanced dietary and lifestyle modifications, and 22% met criteria for pharmacologic intervention. Elevated triglycerides were more prevalent, with 51% meeting criteria for intervention. At 1 year, 25% achieved goal triglycerides with diet and lifestyle changes, 38% met criteria for advanced dietary modifications, and 37% qualified for antihyperlipidemic medications. CONCLUSIONS: More than one-half of children with NAFLD met intervention thresholds for dyslipidemia. Based on the burden of clinically relevant dyslipidemia, lipid screening in children with NAFLD is warranted. Clinicians caring for children with NAFLD should be familiar with lipid management
