Binge flying: Behavioural addiction and climate change
Recent popular press suggests that âbinge flyingâ constitutes a new site of behavioural addiction. We theoretically appraise and empirically support this proposition through interviews with consumers in Norway and the United Kingdom conducted in 2009. Consistent findings from across two national contexts evidence a growing negative discourse towards frequent short-haul tourist air travel and illustrate strategies of guilt suppression and denial used to span a cognitive dissonance between the short-term personal benefits of tourism and the air travelâs associated long-term consequences for climate change. Tensions between tourism consumption and changing social norms towards acceptable flying practice exemplify how this social group is beginning to (re)frame what constitutes âexcessiveâ holiday flying, despite concomitantly continuing their own frequent air travels
Anisotropy parameterization development and evaluation for glacier surface albedo retrieval from satellite observations.
Glacier albedo determines the net shortwave radiation absorbed at the glacier surface and plays a crucial role in glacier energy and mass balance. Remote sensing techniques are efficient means to retrieve glacier surface albedo over large and inaccessible areas and to study its variability. However, corrections of anisotropic reflectance of glacier surface have been established for specific shortwave bands only, such as Landsat 5 Thematic Mapper (L5/TM) band 2 and band 4, which is a major limitation of current retrievals of glacier broadband albedo. In this study, we calibrated and evaluated four anisotropy correction models for glacier snow and ice, applicable to visible, near-infrared and shortwave-infrared wavelengths using airborne datasets of Bidirectional Reflectance Distribution Function (BRDF). We then tested the ability of the best-performing anisotropy correction model, referred to from here on as the âupdated modelâ, to retrieve albedo from L5/TM, Landsat 8 Operational Land Imager (L8/OLI) and Moderate Resolution Imaging Spectroradiometer (MODIS) imagery, and evaluated these results with field measurements collected on eight glaciers around the world. Our results show that the updated model: (1) can accurately estimate anisotropic factors of reflectance for snow and ice surfaces; (2) generally performs better than prior approaches for L8/OLI albedo retrieval but is not appropriate for L5/TM; (3) generally retrieves MODIS albedo better than the MODIS standard albedo product (MCD43A3) in both absolute values and glacier albedo temporal evolution, i.e., exhibiting both fewer gaps and better agreement with field observations. As the updated model enables anisotropy correction of a maximum of 10 multispectral bands and is implemented in Google Earth Engine (GEE), it is promising for observing and analyzing glacier albedo at large spatial scales
An investigation of the three-way joint coaching alliance: a social identity theory perspective
This study builds upon the previous research that recognised coaching as a triangular political space generating power relationships. We integrate social identity theory into this power negotiation process and consider that the ultimate purpose of coaching is to facilitate a shared coaching identity among all related collaborators. To gain in-depth understanding of factors that promote a three-way joint coaching identity; we conducted 25 critical incident interviews and two levels of Q-sorting (n = 10) with coaches, coachees and organisational stakeholders. The research results indicated that a workplace coaching identity is a flexible space underpinned by coachesâ attitude, all collaboratorsâ positions and the contracting process. Coachesâ accommodated communication techniques determine the relationship climate (instrumental or influential). Coachesâ position in the coaching space regulates their self-interests and motivation to change. Moreover, a transparent contracting process encourages communication flows and psychological exchanges among all collaborators that may gain more support from stakeholders

Proteogenomic landscape of breast cancer tumorigenesis and targeted therapy
The integration of mass spectrometry-based proteomics with next-generation DNA and RNA sequencing profiles tumors more comprehensively. Here this "proteogenomics" approach was applied to 122 treatment-naive primary breast cancers accrued to preserve post-translational modifications, including protein phosphorylation and acetylation. Proteogenomics challenged standard breast cancer diagnoses, provided detailed analysis of the ERBB2 amplicon, defined tumor subsets that could benefit from immune checkpoint therapy, and allowed more accurate assessment of Rb status for prediction of CDK4/6 inhibitor responsiveness. Phosphoproteomics profiles uncovered novel associations between tumor suppressor loss and targetable kinases. Acetylproteome analysis highlighted acetylation on key nuclear proteins involved in the DNA damage response and revealed cross-talk between cytoplasmic and mitochondrial acetylation and metabolism. Our results underscore the potential of proteogenomics for clinical investigation of breast cancer through more accurate annotation of targetable pathways and biological features of this remarkably heterogeneous malignancy

Drama, Landscape and Memory: To Be is to Be in Place
This paper is based on research that sought to identify the cognitive and emotive effect of a collaborative drama event that took place in a unique landscape. Particular leitmotifs emerged from the research concerning identity and groups, the resonance of landscape, collective and childhood memory and the particularity of site-specific theatre. In this paper the author deconstructs two of these: landscape and memory. The concluding theories suggest that events of this nature can offer a sense of 'being in place'. The paper draws on 2 years of qualitative research of a many-layered theatre education project taking place, annually, in Cornwall, England. Approximately 70 undergraduate students have taken this project to 3,500 primary school pupils, 100 primary school staff and 2,000 adult audience members each year; the practical research is drawn from all these participants, particularly the students
