Novel N4-like bacteriophages of pectobacterium atrosepticum

Pectobacterium atrosepticum is an economically important phytopathogen that is responsible for potato blackleg and soft rot, and for which current control strategies are limited. In this study, stem samples of potato crops exhibiting blackleg were taken from three farms in Co. Cork, Ireland, and they were found to be infected with P. atrosepticum. Three closely related bacteriophages (phages) that are specific to this phytopathogen were isolated and characterized, namely vB_PatP_CB1, vB_PatP_CB3, and vB_PatP_CB4 (abbreviated as CB1, CB3, and CB4). Both CB1 and CB3 were determined to infect 12 strains and CB4 10 strains of the 19 strains of P. atrosepticum tested. Morphology, latent periods, burst sizes, and their stability at various temperatures and pHs were also examined. Genome sequencing of the three phages revealed that they shared a minimum nucleotide identity of 93% with each other. Their genomes exhibited an Enquartavirinae genome organization, possessing several conserved proteins that were associated with phages of this group, like the type species Escherichia virus N4. Tandem electrospray ionization-mass spectrometry (ESI-MS/MS) allowed for the identification of ten structural proteins that form the virion of CB1, six that are conserved in phage N4. Biocontrol experiments demonstrated that the phages suppress soft rot formation upon co-inoculation with P. atrosepticum on whole tubers. The results of this study indicate that CB1 related phages could be good candidates for phage-based control

Consumer perspectives on acceptability of trauma-focused cognitive behavioral therapy in Tanzania and Kenya: A mixed methods study

Background There is a substantial mental health treatment gap globally. Increasingly, mental health treatments with evidence of effectiveness in western countries have been adapted and tested in culturally and contextually distinct countries. Findings from these studies have been promising, but to better understand treatment outcome results and consider broader scale up, treatment acceptability needs to be assessed and better understood. This mixed methods study aimed to examine child and guardian acceptability of trauma-focused cognitive behavioral therapy (TF-CBT) in two regions in Tanzania and Kenya and to better understand how TF-CBT was perceived as helpful for children and guardians. Methods Participants were 315 children (7–13), who experienced the death of one or both parents and 315 guardians, both of whom participated in TF-CBT as part of a randomized controlled trial conducted in Tanzania and Kenya. The study used mixed methods, with quantitative evaluation from guardian perspective (N=315) using the Treatment Acceptability Questionnaire (TAQ) and the Client Satisfaction Questionnaire-8 (CSQ-8). Acceptability was assessed qualitatively from both guardian and child perspectives. Qualitative evaluation involved analysis using stratified selection to identify 160 child and 160 guardian interviews, to allow exploration of potential differences in acceptability by country, setting (urban/rural), and youth age (younger/older). Results Guardians reported high acceptability on the TAQ and, using an interpretation guide from U.S.-based work, medium acceptability on the CSQ-8. Guardians and children noted high acceptability in the qualitative analysis, noting benefits that correspond to TF-CBT’s therapeutic goals. Analyses exploring differences in acceptability yielded few differences by setting or child age but suggested some potential differences by country. Conclusion Quantitative and qualitative data converged to suggest high acceptability of TF-CBT from guardian and child perspectives in Tanzania and Kenya. Findings add to accumulating evidence of high TF-CBT acceptability from Zambia and other countries (United States, Norway, Australia). Plain Language Summary: Evidence-based treatments have been shown to be effective in countries and regions that are contextually and culturally distinct from where they were developed. But, perspectives of consumers on these treatments have not been assessed regularly or thoroughly. We used open-ended questions and rating scales to assess guardian and youth perspectives on a group-based, cognitive behavioral treatment for children impacted by parental death, in regions within Tanzania and Kenya. Our findings indicate that both guardians and youth found the treatment to be very acceptable. Nearly all guardians talked about specific benefits for the child, followed by benefits for the family and themselves. Eighty percent of youth mentioned benefits for themselves and all youth said they would recommend the program to others. Benefits mentioned by guardians and youth corresponded to treatment goals (improved mood/feelings or behavior, less distress when thinking about the parent/s’ death). Both guardians and children named specific aspects of the treatment that they liked and found useful. Dislikes and challenges of the treatment were less frequently mentioned, but point to areas where acceptability could be further improved. Recommendations from participants also offer areas where acceptability could be improved, namely guardians’ recommendation that the treatment also address non-mental health needs and offer some follow-up or opportunity to participate in the program again. Our study provides an example of how to assess acceptability and identify places to further enhance acceptability

PPPC 4 DM ID: A Poor Particle Physicist Cookbook for Dark Matter Indirect Detection

We provide ingredients and recipes for computing signals of TeV-scale Dark Matter annihilations and decays in the Galaxy and beyond. For each DM channel, we present the energy spectra of electrons and positrons, antiprotons, antideuterons, gamma rays, neutrinos and antineutrinos e, mu, tau at production, computed by high-statistics simulations. We estimate the Monte Carlo uncertainty by comparing the results yielded by the Pythia and Herwig event generators. We then provide the propagation functions for charged particles in the Galaxy, for several DM distribution profiles and sets of propagation parameters. Propagation of electrons and positrons is performed with an improved semi-analytic method that takes into account position-dependent energy losses in the Milky Way. Using such propagation functions, we compute the energy spectra of electrons and positrons, antiprotons and antideuterons at the location of the Earth. We then present the gamma ray fluxes, both from prompt emission and from Inverse Compton scattering in the galactic halo. Finally, we provide the spectra of extragalactic gamma rays. All results are available in numerical form and ready to be consumed.Comment: 57 pages with many figures and tables. v4: updated to include a 125 higgs boson, computation and discussion of extragalactic spectra corrected, some other typos fixed; all these corrections and updates are reflected on the numerical ingredients available at http://www.marcocirelli.net/PPPC4DMID.html they correspond to Release 2.

Biosemiotics, politics and Th.A. Sebeok’s move from linguistics to semiotics

This paper will focus on the political implications for the language sciences of Sebeok’s move from linguistics to a global semiotic perspective, a move that ultimately resulted in biosemiotics. The paper will seek to make more explicit the political bearing of a biosemiotic perspective in the language sciences and the human sciences in general. In particular, it will discuss the definition of language inherent in Sebeok’s project and the fundamental re-drawing of the grounds of linguistic debate heralded by Sebeok’s embrace of the concept of modelling. Thus far, the political co-ordinates of the biosemiotic project have not really been made explicit. This paper will therefore seek to outline 1. how biosemiotics enables us to reconfigure our understanding of the role of language in culture; 2. how exaptation is central to the evolution of language and communication, rather than adaptation; 3. how communication is the key issue in biosphere, rather than language, not just because communication includes language but because the language sciences often refer to language as if it were mere “chatter”, “tropes” and “figures of speech”; 4. how biosemiotics, despite its seeming “neutrality” arising from its transdisciplinarity, is thoroughly political; 5. how the failure to see the implications of the move from linguistics to semiotics arises from the fact that biosemiotics is devoid of old style politics, which is based on representation (devoid of experience) and “construction of [everything] in discourse” (which is grounded in linguistics, not communication study). In contrast to the post-“linguistic turn” idea that the world is “constructed in discourse”, we will argue that biosemiotics entails a reconfiguration of the polis and, in particular, offers the chance to completely reconceptualise ideology

Proceedings of the 3rd Biennial Conference of the Society for Implementation Research Collaboration (SIRC) 2015: advancing efficient methodologies through community partnerships and team science

It is well documented that the majority of adults, children and families in need of evidence-based behavioral health interventionsi do not receive them [1, 2] and that few robust empirically supported methods for implementing evidence-based practices (EBPs) exist. The Society for Implementation Research Collaboration (SIRC) represents a burgeoning effort to advance the innovation and rigor of implementation research and is uniquely focused on bringing together researchers and stakeholders committed to evaluating the implementation of complex evidence-based behavioral health interventions. Through its diverse activities and membership, SIRC aims to foster the promise of implementation research to better serve the behavioral health needs of the population by identifying rigorous, relevant, and efficient strategies that successfully transfer scientific evidence to clinical knowledge for use in real world settings [3]. SIRC began as a National Institute of Mental Health (NIMH)-funded conference series in 2010 (previously titled the “Seattle Implementation Research Conference”; $150,000 USD for 3 conferences in 2011, 2013, and 2015) with the recognition that there were multiple researchers and stakeholdersi working in parallel on innovative implementation science projects in behavioral health, but that formal channels for communicating and collaborating with one another were relatively unavailable. There was a significant need for a forum within which implementation researchers and stakeholders could learn from one another, refine approaches to science and practice, and develop an implementation research agenda using common measures, methods, and research principles to improve both the frequency and quality with which behavioral health treatment implementation is evaluated. SIRC’s membership growth is a testament to this identified need with more than 1000 members from 2011 to the present.ii SIRC’s primary objectives are to: (1) foster communication and collaboration across diverse groups, including implementation researchers, intermediariesi, as well as community stakeholders (SIRC uses the term “EBP champions” for these groups) – and to do so across multiple career levels (e.g., students, early career faculty, established investigators); and (2) enhance and disseminate rigorous measures and methodologies for implementing EBPs and evaluating EBP implementation efforts. These objectives are well aligned with Glasgow and colleagues’ [4] five core tenets deemed critical for advancing implementation science: collaboration, efficiency and speed, rigor and relevance, improved capacity, and cumulative knowledge. SIRC advances these objectives and tenets through in-person conferences, which bring together multidisciplinary implementation researchers and those implementing evidence-based behavioral health interventions in the community to share their work and create professional connections and collaborations
