Effects of white-tailed deer herbivory on upland plant communities in the Piedmont of South Carolina

White-tailed deer (Odocoileus virginianus) is an important game species and the largest native herbivore in South Carolina. Intense deer herbivory can result in browse lines, reduced regeneration of tree species, and the extirpation of plant species. The impact of white-tailed deer has been studied throughout much of its northern range, but there has been little long-term research into the impact of deer on forests communities in the Southeast. This study measures impacts of deer herbivory 13 years after clearcutting upland hardwood stands in the Clemson Experimental Forest by comparing forest and plant communities inside and outside exclosures. An initial study conducted in 2005, 1 year after the clearcut, concluded that deer density had no impact on these communities. To determine the long-term impacts of herbivory, the plots were resurveyed 13 years later. Regeneration of seedling, sapling and overstory oaks was unimpacted by deer herbivory (p=.61, p=.58, p=.45). In fact, the plots outside the exclosures had a higher population of 4in DBH oaks compared to the plots inside enclosures (p=0.09). There was significantly higher plant species richness outside the exclosures compared to inside (p=0.08). Shannon’s diversity index was not statistically different between treatments (p\u3e0.1). Both treatments had a similar number of invasive species (p=0.81). Exclosures had 5,000 more Japanese honeysuckle (Lonicera japonica) per acre compared to outside the exclosure. There was significantly higher vine regeneration inside the exclosures (

Putting into Question the Imaginary of Recovery: A Dialectical Reading of the Global Financial Crisis and its Aftermath

In this article we put into question the discourses that emerged during the Global Financial Crisis (GFC) and that coalesced around a particular socio-economic imaginary of ?recovery? over the period 2009-2012. Our reading of these discourses is very much guided by the notion of the dialectic as developed by Fredric Jameson, and as such this paper can be read as attempt to put his theoretical ideas to work. Through our dialectical reading we aim to create a certain estrangement effect that makes the imaginary of recovery seem very odd and unnatural. In order to achieve such an effect we postulate four theses which are deliberately antagonistic: first, that there has been no ?crisis of capitalism?; second, that we must change the valence of the GFC from negative to positive; third, that the relationship between finance capitalism and ?free markets? is deeply contradictory; and fourth, that we must resist the regulation discourse

Affecting qualitative health psychology

The ‘affective turn’ is a contemporary movement within the humanities, social science and psychology to investigate affect, emotion and feeling as hybrid phenomena jointly constituted from both biological and social influences. Health and illness are themselves jointly constituted in this way, and many of the topics, concerns and methods of health psychology are strongly permeated by affective phenomena. Qualitative research in health psychology might therefore benefit by engaging with this work. This paper describes some features of the affective turn, and suggests theories, terminology and methods that might be useful

RE: pedagogy – after neutrality

Within the UK and in many parts of the world, official accounts of what it is to make sense of religion are framed within a rhetorics of neutrality in which such study is premised upon the possibility of dispassionate engagement and analysis. This paper, which is largely theoretical in scope, explores both the affordances and the costs of such an approach which has become ‘black boxed’ on account of the work that it achieves. A series of new orientations within the academy that are broadly associated with post-structuralist philosophies, feminist and post-colonial studies, together with insights from Science and Technology Studies, question the plausibility of these claims for neutrality whilst in turn raising a series of new questions and priorities. It therefore becomes necessary to re-think and re-frame what it is to make sense of religious and cultural difference after neutrality. The gathering and co-ordination of new planes of sense-making that are responsive to an emergent series of epistemological, ontological, and ethical orientations are considered. Some of the distinctive pedagogical implications of such an approach that engages material practice, difference and uncertainty are then entertained

Germline variation in inflammation-related pathways and risk of Barrett's oesophagus and oesophageal adenocarcinoma

Esophageal adenocarcinoma (EA) incidence has risen sharply in Western countries over recent decades. Local and systemic inflammation, operating downstream of disease-associated exposures, is considered an important contributor to EA pathogenesis. Several risk factors have been identified for EA and its precursor, Barrett’s esophagus (BE), including symptomatic reflux, obesity, and smoking. The role of inherited genetic susceptibility remains an area of active investigation. To explore whether germline variation related to inflammatory processes influences susceptibility to BE/EA, we used data from a genome-wide association study (GWAS) of 2,515 EA cases, 3,295 BE cases, and 3,207 controls. Our analysis included 7,863 single nucleotide polymorphisms (SNPs) in 449 genes assigned to five pathways: cyclooxygenase (COX), cytokine signaling, oxidative stress, human leukocyte antigen, and NFκB. A principal components-based analytic framework was employed to evaluate pathway-level and gene-level associations with disease risk. We identified a significant signal for the COX pathway in relation to BE risk (P=0.0059, FDR q=0.03), and in gene-level analyses found an association with MGST1 (microsomal glutathione-S-transferase 1; P=0.0005, q=0.005). Assessment of 36 MGST1 SNPs identified 14 variants associated with elevated BE risk (q<0.05). Of these, four were subsequently confirmed (P<5.5 × 10−5) in a meta-analysis encompassing an independent set of 1,851 BE cases and 3,496 controls. Three of these SNPs (rs3852575, rs73112090, rs4149204) were associated with similar elevations in EA risk. This study provides the most comprehensive evaluation of inflammation-related germline variation in relation to risk of BE/EA, and suggests that variants in MGST1 influence disease susceptibility

Affect--or feeling (after Leys)

In recent years the ‘affective turn’ has permeated the arts, humanities, social sciences, and psychology, but like any influential academic movement has not escaped critique. We outline and agree in general terms with the critique by Leys (2011b), which emphasises the influence of the basic emotion paradigm; the dualisms that accompany its deployment; and concerns regarding intentionality and meaning. We then propose an alternate approach to affect and feeling, derived from the philosophies of Whitehead and Langer; demonstrate how this avoids the endorsement of cognitivism to which Leys critique succumbs; illustrate the strengths of this approach with respect to analyses of former U.S. President Reagan; and highlight two strengths of affect theory which are compatible with it. We conclude that our approach closes the intentionality gap that Leys identifies whilst retaining a fruitful emphasis upon the affective realm

The feasibility of an exercise intervention in males at risk of oesophageal adenocarcinoma: a randomized controlled trial

Objective: To investigate the feasibility and safety of a 24-week exercise intervention, compared to control, in males with Barrett's oesophagus, and to estimate the effect of the intervention, compared to control, on risk factors associated with oesophageal adenocarcinoma development. Methods: A randomized controlled trial of an exercise intervention (60 minutes moderate-intensity aerobic and resistance exercise five days/week over 24 weeks; one supervised and four unsupervised sessions) versus attention control (45 minutes stretching five days/week over 24 weeks; one supervised and four unsupervised sessions) in inactive, overweight/obese (25.0-34.9 kg/m2) males with Barrett's oesophagus, aged 18-70 years. Primary outcomes were obesity-associated hormones relevant to oesophageal adenocarcinoma risk (circulating concentrations of leptin, adiponectin, interleukin-6, tumour necrosis factor-alpha, C-reactive protein, and insulin resistance HOMA). Secondary outcomes included waist circumference, body composition, fitness, strength and gastro-oesophageal reflux symptoms. Outcomes were measured at baseline and 24-weeks. Intervention effects were analysed using generalised linear models, adjusting for baseline value. Results: Recruitment was difficult in this population with a total of 33 participants recruited (target sample size: n = 80); 97% retention at 24-weeks. Adherence to the exercise protocol was moderate. No serious adverse events were reported. A statistically significant intervention effect (exercise minus control) was observed for waist circumference (-4.5 95%CI -7.5, -1.4 cm; p &lt; 0.01). Effects on primary outcomes were not statistically significant. Conclusion: This small, exploratory trial provides important information to inform future trial development including recruitment rates and estimates of effect sizes on outcomes related to oesophageal adenocarcinoma risk. Future trials should investigate a combined dietary and exercise intervention to achieve greater weight loss in this population and relax inclusion criteria to maximize recruitment.

Mendelian Randomization Study of Body Mass Index and Colorectal Cancer Risk

High body mass index (BMI) is consistently linked to increased risk of colorectal cancer (CRC) for men, whereas the association is less clear for women. As risk estimates from observational studies may be biased and/or confounded, we conducted a Mendelian randomization study to estimate the causal association between BMI and CRC
