I am your worst fear, I am your best fantasy: new approaches to slash fiction
This thesis uses slash fan fiction produced for the CW television series Supernatural to suggest two new slash typologies. While existing frameworks â romantopia (concerned with sex) and intimatopia (concerned with intimacy) â are useful, I argue that many slash stories fall outside the scope of these two terms into two newly proposed categories: paratopia and monstropia. Paratopic slash is centrally concerned with psychological change or geographical repositioning and realises, like romantopia and intimatopia, potentials of homosocial desire. Monstropic slash is centrally concerned with perversity and realises potentials of homosexual panic; it is a genre of slash fiction until now unexplored by slash scholarship. To illustrate these frameworks I discuss Supernatural slash stories in detail. Supernatural was chosen to illustrate both paratopia and monstropia because it is arguably a text that promotes homosexual panic as much as it does homosocial desire. I also argue that Supernatural slash, which would ordinarily be classified as romantopic or intimatopic, is paratopic due to the changes necessary to negotiate the charactersâ homophobia and authentically present them in either sexual or intimate love. In conclusion, I argue that paratopia and monstropia are useful frameworks for understanding the âother worldsâ that slash inhabits â worlds beyond the reach of âtopiasâ romantopia and intimatopia
MARKET STRUCTURE AND INNOVATION INTENSITY IN AGRICULTURAL BIOTECH
Consolidations and spin-offs in the agricultural biotechnology industry and the growing links of multinational corporations with the food and feed industry have been the subject of considerable discussion among academics, policy makers, consumers, and farmers. Most of the research by academic and overnment institutions has focused on the reasons for consolidation. Little theoretical or empirical research has examined the impact of this consolidation. We adapt an endogenous growth model of industry structure and R&D to agricultural biotechnology and empirically estimate the model. These empirical estimates, the main focus of the paper, indicate that industry consolidation influences the amount and direction of research, which then feeds back to influence industry structure.Agribusiness, Marketing, Research and Development/Tech Change/Emerging Technologies,
Crowdsourcing Image Extraction and Annotation: Software Development and Case Study
We describe the development of web-based software that facilitates large-scale, crowdsourced image extraction and annotation within image-heavy corpora that are of interest to the digital humanities. An application of this software is then detailed and evaluated through a case study where it was deployed within Amazon Mechanical Turk to extract and annotate faces from the archives of Time magazine. Annotation labels included categories such as age, gender, and race that were subsequently used to train machine learning models. The systemization of our crowdsourced data collection and worker quality verification procedures are detailed within this case study. We outline a data verification methodology that used validation images and required only two annotations per image to produce high-fidelity data that has comparable results to methods using five annotations per image. Finally, we provide instructions for customizing our software to meet the needs for other studies, with the goal of offering this resource to researchers undertaking the analysis of objects within other image-heavy archives
Polarimetric airborne scientific instrument, mark 2, an iceâsounding airborne synthetic aperture radar for subglacial 3DÂ imagery
Polarimetric Airborne Scientific INstrument, mark 2 (PASIN2) is a 150 MHz coherent
pulsed radar with the purpose of deep ice sounding for bedrock, subglacial channels and
iceâwater interface detection in Antarctica. It is designed and operated by the British
Antarctic Survey from 2014. With multiple antennas, oriented along and acrossâtrack, for
transmission and reception, it enables polarimetric 3D estimation of the ice base with a
single pass, reducing the gridding density of the survey paths. The offâline data processing
stream consists of channel calibration; 2D synthetic aperture radar (SAR) imaging based
on backâprojection, for alongâtrack and range dimensions; and finally, a direction of
arrival estimation (DoA) of the remaining acrossâtrack angle, by modifying the nonâlinear
MUSIC algorithm. Calibration flights, during the Antarctic Summer campaigns in 16/17
and 19/20 seasons, assessed and validated the instrument and processing performances.
Imaging flights over ice streams and ice shelves close to grounding lines demonstrate the
3D sensing capabilities. By resolving directional ambiguities and accounting for reflector
acrossâtrack location, the true ice thickness and bed elevation are obtained, thereby
removing the error of the usual assumption of vertical DoA, that greatly influence the
output of flow models of ice dynamics

Prevalence of occupational moral injury and post-traumatic embitterment disorder: a systematic review and meta-analysis.
ObjectivesOccupational moral injury and post-traumatic embitterment disorder (PTED) describe the psychological distress caused by exposure to injustice at work. This meta-analysis aims to determine the prevalence of occupational moral injury and PTED and establish whether prevalence estimates differ depending on occupation.DesignA systematic review and meta-analysis.Data sourcesGoogle Scholar, PubMed, APA PsycINFO, Web of Science Core Collection, Scopus, ScienceDirect and Sage Journals Online were searched in June 2020 and updated in November 2022.Eligibility criteria for selecting studiesObservational studies that measured prevalence or average scores of moral injury, or PTED in any occupational group and any geographical location.Data extraction and synthesisTwo independent reviewers screened and coded eligible studies. Study design, participant demographics, sampling method, location, measurement tool and prevalence or average scores were extracted. Risk of bias was assessed using the Quality Assessment Checklist for Prevalence Studies tool. Meta-analysis was conducted using random effects models. Results that could not be combined were summarised qualitatively in a narrative synthesis using the Guidance for Systematic Reviews.ResultsIn total, 88 studies across armed forces and veterans, healthcare, first responders, educators, journalists, child protection service employees, the unemployed, public-sector employees and mixed occupations were included. Studies included in each separate meta-analysis based on the measure used ranged from 2 to 30. The pooled prevalence of clinically relevant moral injury in healthcare professionals was 45%, and exposure to any potentially morally injurious event (PMIE) across occupations was 67%. Exposure to transgressions by others and betrayal was significantly lower in the armed forces than civilian occupations. Pooled prevalence of PTED across occupations was 26%.ConclusionExposure to PMIEs, moral injury symptoms and PTED are prevalent at work and exposure to transgressions by others and betrayal are more likely in civilian occupations than the armed forces.Prospero registration numberCRD42020191766
SOX11 expression correlates to promoter methylation and regulates tumor growth in hematopoietic malignancies
<p>Abstract</p> <p>Background</p> <p>The transcription factor SOX11 plays an important role in embryonic development of the central nervous system (CNS) and is expressed in the adult immature neuron but is normally not expressed in any other adult tissue. It has recently been reported to be implicated in various malignant neoplasms, including several lymphoproliferative diseases, by its specific expression and in some cases correlation to prognosis. SOX11 has been shown to prevent gliomagenesis <it>in vivo </it>but the causes and consequences of aberrant expression of <it>SOX11 </it>outside the CNS remain unexplained.</p> <p>Results</p> <p>We now show the first function of <it>SOX11 </it>in lymphoproliferative diseases, by demonstrating <it>in vitro </it>its direct involvement in growth regulation, as assessed by siRNA-mediated silencing and ectopic overexpression in hematopoietic malignancies. Gene Chip analysis identified cell cycle regulatory pathways, including Rb-E2F, to be associated with SOX11-induced growth reduction. Furthermore, promoter analysis revealed that <it>SOX11 </it>is silenced through DNA methylation in B cell lymphomas, suggesting that its regulation is epigenetically controlled.</p> <p>Conclusions</p> <p>The data show that SOX11 is not a bystander but an active and central regulator of cellular growth, as both siRNA-mediated knock-down and ectopic overexpression of <it>SOX11 </it>resulted in altered proliferation. Thus, these data demonstrate a tumor suppressor function for <it>SOX11 </it>in hematopoietic malignancies and revealed a potential epigenetic regulation of this developmentally involved gene.</p

iCOP:live forensics to reveal previously unknown criminal media on P2P networks
The increasing levels of criminal media being shared in peer-to-peer (P2P) networks pose a significant challenge to law enforcement agencies. One of the main priorities for P2P investigators is to identify cases where a user is actively engaged in the production of child sexual abuse (CSA) media â they can be indicators of recent or on-going child abuse. Although a number of P2P monitoring tools exist to detect paedophile activity in such networks, they typically rely on hash value databases of known CSA media. As a result, these tools are not able to adequately triage the thousands of results they retrieve, nor can they identify new child abuse media that are being released on to a network. In this paper, we present a new intelligent forensics approach that incorporates the advantages of artificial intelligence and machine learning theory to automatically flag new/previously unseen CSA media to investigators. Additionally, the research was extensively discussed with law enforcement cybercrime specialists from different European countries and Interpol. The approach has been implemented into the iCOP toolkit, a software package that is designed to perform live forensic analysis on a P2P network environment. In addition, the system offers secondary features, such as showing on-line sharers of known CSA files and the ability to see other files shared by the same GUID or other IP addresses used by the same P2P client. Finally, our evaluation on real CSA case data shows high degrees of accuracy, while hands-on trials with law enforcement officers demonstrate the toolkitâs complementarity to extant investigative workflows
