Ecocentrism is the broadest term for worldviews that recognize intrinsic value in all lifeformsand ecosystems themselves, including their abiotic components. Anthropocentrism, in contrast, values other lifeforms and ecosystems insofar as they are valuable for human well-being, preferences and interests. Herein, the authors examine the roots of ecocentrism and discuss its mixed history of international recognition. They argue that non-human nature has intrinsic value irrespective of human preferences or valuation, and they refute the claim that ecocentrism is misanthropic. They then summarize four key examples from the academic literature in which anthropocentrism fails to provide an ethic adequate for respecting and protecting planet Earth and its inhabitants. The authors conclude that ecocentrism is essential for solving our unprecedented environmental crisis, arguing its importance from four perspectives: ethical, evolutionary, spiritual and ecological. They contend that a social transformation towards ecocentrism is not only an ethical but a practical imperative, and they urge support for ecocentric understanding and practices.

Since 2009, the Working Group on the ‘Anthropocene’ (or, commonly, AWG for Anthropocene Working Group), has been critically analysing the case for formalization of this proposed but still informal geological time unit. The study to date has mainly involved establishing the overall nature of the Anthropocene as a potential chronostratigraphic/geochronologic unit, and exploring the stratigraphic proxies, including several that are novel in geology, that might be applied to its characterization and definition. A preliminary summary of evidence and interim recommendations was presented by the Working Group at the 35th International Geological Congress in Cape Town, South Africa, in August 2016, together with results of voting by members of the AWG indicating the current balance of opinion on major questions surrounding the Anthropocene. The majority opinion within the AWG holds the Anthropocene to be stratigraphically real, and recommends formalization at epoch/series rank based on a mid-20th century boundary. Work is proceeding towards a formal proposal based upon selection of an appropriate Global boundary Stratotype Section and Point (GSSP), as well as auxiliary stratotypes. Among the array of proxies that might be used as a primary marker, anthropogenic radionuclides associated with nuclear arms testing are the most promising; potential secondary markers include plastic, carbon isotope patterns and industrial fly ash. All these proxies have excellent global or near-global correlation potential in a wide variety of sedimentary bodies, both marine and non-marine.

Middle adolescents (15–17 years old) are prone to increased risk taking and emotional instability. Emotion dysregulation contributes to a variety of psychosocial difficulties in this population. A discipline such as yoga offered during school may increase emotion regulation, but research in this area is lacking. This study was designed to evaluate the impact of a yoga intervention on the emotion regulation of high school students as compared to physical education (PE). In addition, the potential mediating effects of mindful attention, self-compassion, and body awareness on the relationship between yoga and emotion regulation were examined. High school students were randomized to participate in a 16-week yoga intervention (n=19) or regular PE (n=18). Pre-post data analyses revealed that emotion regulation increased significantly in the yoga group as compared to the PE group (F (1,32) = 7.50, p = .01, and eta2 = .19). No significant relationship was discovered between the changes in emotion regulation and the proposed mediating variables. Preliminary results suggest that yoga increases emotion regulation capacities of middle adolescents and provides benefits beyond that of PE alone.

The use of Yoga and other complementary healthcare interventions for both clinical and non-clinical populations has increased substantially in recent years. In this context, we describe the implementation of Hatha Yoga in the Mindfulness-Based Stress Reduction (MBSR) program of Kabat-Zinn and colleagues. This is embedded in a more general consideration of Yoga’s place in complementary healthcare. In providing this overview, we comment on the nature and quality of current research on Yoga, summarize current physiological and psychological explanations of its effects, and discuss practical issues related to teacher training and experience.

BACKGROUND: Many breast cancer patients and survivors use yoga to cope with their disease. The aim of this review was to systematically assess and meta-analyze the evidence for effects of yoga on health-related quality of life and psychological health in breast cancer patients and survivors.METHODS: MEDLINE, PsycInfo, EMBASE, CAMBASE, and the Cochrane Library were screened through February 2012. Randomized controlled trials (RCTs) comparing yoga to controls were analyzed when they assessed health-related quality of life or psychological health in breast cancer patients or survivors. Risk of bias was assessed using the Cochrane risk of bias tool. Standardized mean differences (SMD) and 95% confidence intervals (CI) were calculated. RESULTS: Twelve RCTs with a total of 742 participants were included. Seven RCTs compared yoga to no treatment; 3 RCTs compared yoga to supportive therapy; 1 RCT compared yoga to health education; and 1 RCT compared a combination of physiotherapy and yoga to physiotherapy alone. Evidence was found for short-term effects on global health-related quality of life (SMD = 0.62 [95% CI: 0.04 to 1.21]; P = 0.04), functional (SMD = 0.30 [95% CI: 0.03 to 0.57), social (SMD = 0.29 [95% CI: 0.08 to 0.50]; P < 0.01), and spiritual well-being (SMD = 0.41 [95% CI: 0.08; 0.74]; P = 0.01). These effects were, however, only present in studies with unclear or high risk of selection bias. Short-term effects on psychological health also were found: anxiety (SMD = -1.51 [95% CI: -2.47; -0.55]; P < 0.01), depression (SMD = -1.59 [95% CI: -2.68 to -0.51]; P < 0.01), perceived stress (SMD = -1.14 [95% CI:-2.16; -0.12]; P = 0.03), and psychological distress (SMD = -0.86 [95% CI:-1.50; -0.22]; P < 0.01). Subgroup analyses revealed evidence of efficacy only for yoga during active cancer treatment but not after completion of active treatment. CONCLUSIONS: This systematic review found evidence for short-term effects of yoga in improving psychological health in breast cancer patients. The short-term effects on health-related quality of life could not be clearly distinguished from bias. Yoga can be recommended as an intervention to improve psychological health during breast cancer treatment.

PURPOSE: Studies have demonstrated beneficial health effects from yoga interventions in cancer patients, but predominantly in breast cancer. Research on its role in alleviating prostate cancer (PC) patients' side effects has been lacking. Our primary goal was to determine the feasibility of recruiting PC patients on a clinical trial of yoga while they underwent external beam radiation therapy (RT).METHODS: Twice-weekly yoga interventions were offered throughout the RT course (6-9 weeks). Baseline demographic information was collected. Feasibility was declared if 15 of the first 75 eligible PC patients approached (20%) were successfully accrued and completed the intervention. Additional end points included standardized assessments of fatigue, erectile dysfunction (ED), urinary incontinence (UI), and quality of life (QOL) at time points before, during, and after RT. RESULTS: Between May 2013 and June 2014, 68 eligible PC patients were identified. 23 patients (34%) declined, and 45 (56%) consented to the study. 18 (40%) were voluntarily withdrawn due to treatment conflicts. Of the remaining 27, 12 (30%) participated in ≥50% of classes, and 15 (59%) were evaluable. Severity of fatigue scores demonstrated significant variability, with fatigue increasing by week 4, but then improving over the course of treatment (P = .008). ED, UI, and general QOL scores demonstrated reassuringly stable, albeit not significant trends. CONCLUSIONS: A structured yoga intervention of twice-weekly classes is feasible for PC patients during a 6- to 9-week course of outpatient radiotherapy. Preliminary results are promising, showing stable measurements in fatigue, sexual health, UI, and general QOL.

Objective: To examine the efficacy of a 12-week yoga program aimed at reducing binge eating severity. Design: A randomised trial was undertaken assigning participants to yoga (n=45) or wait-list control (n = 45) groups. Of these, 25 in each group were analysed. Participants: A community-based sample of women between 25 and 63 years of age who identified with diagnostic criteria for binge eating disorder (BED) and a BMI > 25 were recruited for the study. Main outcome measures: Primary outcomes included the Binge Eating Scale (BES) and International Physical Activity Questionnaire (IPAQ). Secondary outcomes comprised measures for BMI, hips and waist. Results: For the yoga group, self-reported reductions in binge eating and increases in physical activity were statistically significant. Small yet statistically significant reductions for BMI, hips and waist measurement were obtained. The wait-list control group did not improve significantly on any measures. Conclusion: In conjunction with format weekly sessions, home-based yoga programs are potentially efficacious for the treatment of binge eating. Crown Copyright (C) 2009 Published by Elsevier Ltd.
