Targeting alphas can make coyote control more effective and socially acceptable

Research at the UC Hopland Research and Extension Center (HREC) has improved our understanding of how to reduce sheep depredation while minimizing the impact on coyotes. Analysis of a 14-year data set of HREC coyote-control efforts found that sheep depredation losses were not correlated with the number of coyotes removed in any of three time scales analyzed (yearly, seasonally and monthly) during corresponding intervals for the next 2 years. Field research using radiotelemetry to track coyotes supported and explained this finding. For example, in 1995, dominant “alphas” from four territories were associated with 89% of 74 coyote-killed lambs; “betas” and transients were not associated with any of these kills. Relatively few coyotes were killing sheep, and these animals were difficult to capture by conventional methods at the time of year when depredation was highest. However, selective removal of only the problem alpha coyotes effectively reduced losses at HREC

Of babies and bath water: Is there any place for Austin and Grice in interpersonal pragmatics?

This paper discusses a particular strand of interpersonal pragmatics that may be known as ‘discursive’ pragmatics and attempts to delineate what is entailed in such an approach. Some scholars may characterise it as placing emphasis on participant evaluations, others may foreground the analysis of contextualised and sequential texts, while still others consider it to include both of these. In general, though, discursive pragmatics often seems to involve a reaction to, and a contrast with, so-called Gricean intention-based approaches. In this paper I argue that, far from discarding the insights of Grice, Austin and others, a discursive approach to interpersonal pragmatics should embrace those aspects of non-discursive pragmatics that provide us with a ‘tool-kit’ and a vocabulary for examining talk-in-interaction. At the same time, I will argue that the shortcomings of the speaker-based, intention- focused pragmatics can be compensated for, not by privileging hearer evaluations of meaning, but by taking an ethnographic and, to some extent, ethnomethodological approach to the analysis of naturally-occurring discourse data. By providing a critique of Locher and Watts’ (2005) paradigmatic example of a discursive approach to politeness and then a sample analysis of interactional data, I demonstrate how a combination of insights from Gricean pragmatics and from ethnomethodology allows the analyst to comment on the construction and negotiation of meaning in discourse, without having recourse to notions of either intention or evaluation

Fair publication of qualitative research in health systems: a call by health policy and systems researchers.

[Extract] An open letter from Trisha Greenhalgh et al. [1] to the editors of the British Medical Journal (BMJ) triggered wide debate by health policy and systems researchers (HPSRs) globally on the inadequate recognition of the value of qualitative research and the resulting deficit in publishing papers reporting on qualitative research [2]. One key dimension of equity in health is that researchers are able to disseminate their findings and that they are taken into account in a fair and just manner, so that they can inform health policy and programmes. The Greenhalgh et al. letter and editorial responses [3, 4] were actively discussed within "SHAPES", a thematic group within Health Systems Global, focused on Social Science approaches for research and engagement in health policy & systems (http://healthsystemsglobal.org/twg-group/6/Social-science-approaches-for-research-and-engagement-in-health-policy-amp-systems/) and within EQUINET, a regional network working on health equity research in East and Southern Africa (www.equinetafrica.org). Our discussion precipitated in this follow up open letter/commentary, which has 170 co-signatories. Collectively, we feel that barriers to publication of qualitative research limit publication of many exemplary studies, and their contribution to understanding important dimensions of health care, services, policies and systems

Effects of Lowering Glycemic Index of Dietary Carbohydrate on Plasma Uric Acid: The OmniCarb Randomized Clinical Trial

OBJECTIVE: The effects of carbohydrates on plasma uric acid levels are a subject of controversy. We determined the individual and combined effects of carbohydrate quality (the glycemic index) and quantity (the proportion of total daily energy [percentage of carbohydrates]) on uric acid levels. METHODS: We conducted a randomized, crossover trial of 4 different diets in overweight or obese adults without cardiovascular disease (n = 163). Participants consumed each of 4 diets over a 5-week period, each of which was separated by a 2-week washout period. Body weight was kept constant. The 4 diets were high glycemic index (≥65) with high percentage of carbohydrates (58% kcal), low glycemic index (≤45) with low percentage of carbohydrates (40% kcal), low glycemic index with high percentage of carbohydrates, and high glycemic index with low percentage of carbohydrates. Plasma uric acid levels were measured at baseline and after completion of each 5-week period for comparison between the 4 diets. RESULTS: Of the 163 study participants, 52% were women and 50% were non-Hispanic African American subjects; their mean age was 52.6 years, and their mean ± SD uric acid level was 4.7 ± 1.2 mg/dl. Reducing the glycemic index lowered uric acid levels when the percentage of carbohydrates was low (-0.24 mg/dl; P < 0.001) or high (-0.17 mg/dl; P < 0.001). Reducing the percentage of carbohydrates marginally increased the uric acid level only when the glycemic index was high (P = 0.05). The combined effect of lowering the glycemic index and increasing the percentage of carbohydrates was -0.27 mg/dl (P < 0.001). This effect was observed even after adjustment for concurrent changes in kidney function, insulin sensitivity, and products of glycolysis. CONCLUSION: Reducing the glycemic index lowers uric acid levels. Future studies should examine whether reducing the glycemic index can prevent gout onset or flares

Adipocyte browning and higher mitochondrial function in peri-adrenal but not subcutaneous fat in pheochromocytoma

Context: Patients with pheochromocytoma (pheo) show presence of multilocular adipocytes that express uncoupling protein (UCP) 1 within periadrenal (pADR) and omental (OME) fat depots. It has been hypothesized that this is due to adrenergic stimulation by catecholamines produced by the pheo tumors. Objective: To characterize the prevalence and respiratory activity of brown-like adipocytes within pADR, OME and subcutaneous (SC) fat depots in human adult pheo patients. Design: This was an observational cohort study. Setting: University hospital. Patients: We studied 46 patients who underwent surgery for benign adrenal tumors (21pheos and 25 controls with adrenocortical adenomas). Main outcome measure: We characterized adipocyte browning in pADR, SC, and OME fat depots for histological and immunohistological features, mitochondrial respiration rate, and gene expression. We also determined circulating levels of catecholamines and other browning-related hormones. Results: 11 of 21 pheo pADR adipose samples, but only 1 of 25 pADR samples from control patients, exhibited multilocular adipocytes. The pADR browning phenotype was associated with higher plasma catecholamines and raised UCP1. Mitochondria from multilocular pADR fat of pheo patients exhibited increased rates of coupled and uncoupled respiration. Global gene expression analysis in pADR fat revealed enrichment in β-oxidation genes in pheo patients with multilocular adipocytes. No SC or OME fat depots exhibited aspects of browning. Conclusion: Browning of the pADR depot occurred in half of pheo patients and was associated with increased catecholamines and mitochondrial activity. No browning was detected in other fat depots, suggesting that other factors are required to promote browning in these depots

The Golden Rule:Interfaith Peacemaking and the Charter for Compassion

The Charter for Compassion has been signed by over two million people from around the world and partnered with hundreds of interfaith organizations and cities seeking to put into practice the Golden Rule, common to the main faith traditions, of doing unto others as you would be done by. This article sets the Charter within the context of a post secular international society and faith-based diplomacy, in which religious interreligious initiatives emerge as serious, rather than peripheral, actors in developing sustainable peace making through bottom-up approaches. The article critically engages with the Charter's claim that ‘any interpretation of scripture that breeds violence, hatred or disdain is illegitimate’ while accepting that peaceful interpretations of scriptures are helpful to peace processes where religious actors are involved. The article explores the claims of the Charter for Compassion International as they seek to make peace through compassion, before concluding that the Charter for Compassion is a long-term project aimed at changing hearts and minds but has had limited substantive impact to date

Assessing the quality of reports of systematic reviews in pediatric complementary and alternative medicine

OBJECTIVE: To examine the quality of reports of complementary and alternative medicine (CAM) systematic reviews in the pediatric population. We also examined whether there were differences in the quality of reports of a subset of CAM reviews compared to reviews using conventional interventions. METHODS: We assessed the quality of reports of 47 CAM systematic reviews and 19 reviews evaluating a conventional intervention. The quality of each report was assessed using a validated 10-point scale. RESULTS: Authors were particularly good at reporting: eligibility criteria for including primary studies, combining the primary studies for quantitative analysis appropriately, and basing their conclusions on the data included in the review. Reviewers were weak in reporting: how they avoided bias in the selection of primary studies, and how they evaluated the validity of the primary studies. Overall the reports achieved 43% (median = 3) of their maximum possible total score. The overall quality of reporting was similar for CAM reviews and conventional therapy ones. CONCLUSIONS: Evidence based health care continues to make important contributions to the well being of children. To ensure the pediatric community can maximize the potential use of these interventions, it is important to ensure that systematic reviews are conducted and reported at the highest possible quality. Such reviews will be of benefit to a broad spectrum of interested stakeholders

The Care Work of Access

Current approaches to AI and Assistive Technology (AT) often foreground task completion over other encounters such as expressions of care. Our paper challenges and complements such task-completion approaches by attending to the care work of access—the continual affective and emotional adjustments that people make by noticing and attending to one another. We explore how this work impacts encounters among people with and without vision impairments who complete tasks together. We find that bound up in attempts to get things done are concerns for one another and how well people are doing together. Reading this work through emerging disability studies and feminist STS scholarship, we account for two important forms of work that give rise to access: (1) mundane attunements and (2) noninnocent authorizations. Together these processes work as sensitizing concepts to help HCI scholars account for the ways that intelligent ATs both produce access while sometimes subverting people with disabilities
