When Reporters get Hands-on with Robo-writing: Professionals Consider Automated Journalism’s Capabilities and Consequences

The availability of data feeds, the demand for news on digital devices, and advances in algorithms are helping to make automated journalism more prevalent. This article extends the literature on the subject by analysing professional journalists’ experiences with, and opinions about, the technology. Uniquely, the participants were drawn from a range of news organizations—including the BBC, CNN, and Thomson Reuters—and had first-hand experience working with robo-writing software provided by one of the leading technology suppliers. The results reveal journalists’ judgements on the limitations of automation, including the nature of its sources and the sensitivity of its “nose for news”. Nonetheless, journalists believe that automated journalism will become more common, increasing the depth, breadth, specificity, and immediacy of information available. While some news organizations and consumers may benefit, such changes raise ethical and societal issues and, counter-intuitively perhaps, may increase the need for skills—news judgement, curiosity, and scepticism—that human journalists embody

Analyzing the Effects of Neutron Polarizabilities in Elastic Compton Scattering off 3{}^3He

Motivated by the fact that a polarized ${}^3$He nucleus behaves as an `effective' neutron target, we examine manifestations of neutron electromagnetic polarizabilities in elastic Compton scattering from the Helium-3 nucleus. We calculate both unpolarized and double-polarization observables using chiral perturbation theory to next-to-leading order (${\mathcal O}(e^2 Q)$) at energies, $\omega \leq m_{\pi}$, where $m_{\pi}$ is the pion mass. Our results show that the unpolarized differential cross section can be used to measure neutron electric and magnetic polarizabilities, while two double-polarization observables are sensitive to different linear combinations of the four neutron spin polarizabilities. [Note added in 2018] The qualitative conclusions and analytic formulae presented in this paper are correct, but several of the numerical results are wrong: see the erratum posted as arXiv:1804.01206 for further details. A full suite of corrected numerical results for cross sections and asymmetries can be found in Margaryan et al., arXiv:1804.00956.

Media anti-populism and political parallelism in Latin America

This article examines seven Latin American cases in which anti-populist media played central roles in organizing political opposition to a populist regime, creating a political cleavage between populism and anti-populism which continued to structure both journalism and political competition following the end of populist rule. It contributes to the literature on media and populism by focusing on an actor usually neglected in this literature—the anti-populist media—and by shifting the focus from press freedom to political parallelism. Following the case studies we take up conceptual issues related to the logics of populism and anti-populism and to debates about the applicability of the concept of political parallelism and of mediatization to Latin America and other regions of the global South.Hallin, D.

Effective theory of the Delta(1232) in Compton scattering off the nucleon

We formulate a new power-counting scheme for a chiral effective field theory of nucleons, pions, and Deltas. This extends chiral perturbation theory into the Delta-resonance region. We calculate nucleon Compton scattering up to next-to-leading order in this theory. The resultant description of existing $\gamma$p cross section data is very good for photon energies up to about 300 MeV. We also find reasonable numbers for the spin-independent polarizabilities $\alpha_p$ and $\beta_p$.Comment: 29 pp, 9 figs. Minor revisions. To be published in PR

Assembly of root-associated N₂O-reducing communities of annual crops is governed by selection for nosZ Glade I over Glade II

The rhizosphere is a hotspot for denitrification. The nitrous oxide (N₂O) reductase among denitrifiers and nondenitrifying N₂O reducers is the only known N₂O sink in the biosphere. We hypothesized that the composition of root-associated N₂O-reducing communities when establishing on annual crops depend on soil type and plant species, but that assembly processes are independent of these factors and differ between nosZ clades I and II. Using a pot experiment with barley and sunflower and two soils, we analyzed the abundance, composition, and diversity of soil and root-associated N₂O reducing communities by qPCR and amplicon sequencing of nosZ. Clade I was more abundant on roots compared to soil, while clade II showed the opposite. In barley, this pattern coincided with N₂O availability, determined as potential N₂O production rates, but for sunflower no N₂O production was detected in the root compartment. Root and soil nosZ communities differed in composition and phylogeny-based community analyses indicated that assembly of root-associated N₂O reducers was driven by the interaction between plant and soil type, with inferred competition being more influential than habitat selection. Selection between clades I and II in the root/soil interface is suggested, which may have functional consequences since most clade I microorganisms can produce N₂O

The key components to start and run a business in garden design

Utbildningen Trädgårdsingenjör med designinriktning innefattar kurser som företagsekonomi och marknadsföring vilket kan uppmuntra studenter till att starta eget företag. Att bli egenföretagare kanske är rätt väg att gå men vi frågar oss om utbildningen ger tillräckligt med kompetens för att våga ta det steget. Följande kandidatuppsats ger en inblick i hur verkligheten ser ut för företagare inom trädgårdsdesign. Syftet är att undersöka om det finns några specifika komponenter som behövs för att starta och driva ett företag inom trädgårdsdesign. Uppsatsen ska vidare försöka konstatera vilka av dessa komponenter som är viktigast. Frågeställningen i denna uppsats lyder: Vilka är de viktigaste komponenterna för att starta och driva ett företag inom trädgårdsdesign? Kandidatuppsatsen innefattar en litteraturstudie där befintlig forskning presenteras. Här beskrivs delar som att välja företagsform och vad det innebär att driva ett tjänsteföretag. Därefter nämns viktiga delar i affärsplanen som bland annat berör marknadsföring, marknad, profilering och prissättning. Litteraturstudien avslutas med att förklara vad som gör ett företag inom trädgårdsdesign unikt men också vikten av personliga egenskaper. Denna del följs av kvalitativa intervjuer vars syfte är att bidra med en verklighetsuppfattning. Fyra stycken företag som är verksamma inom trädgårdsdesign har intervjuats för att sedan jämföras med litteraturen. Den avslutande diskussionen behandlar hur väl dessa överensstämmer. Det visar sig att de intervjuade företagen inte i samma utsträckning tillämpar de delar som litteraturen beskriver och föreslår. Endast i något fall har de intervjuade företagen skrivit ner dokument som kan liknas vid en affärsplan. De intervjuade företagen har dock på olika sätt berört delar ur en affärsplan utan att egentligen ha tänkt på det. Trots avsaknaden av en nerskriven affärsplan så har de intervjuade i detta arbete lyckats med sina företag vilket gör att vi kan ifrågasätta behovet av en sådan. Marknadsföring, profilering, marknadsundersökning och prissättning står sig ändå som viktiga komponenter för att lyckas som företagare inom branschen. Ännu en komponent är kunskapen om vad det innebär att sälja tjänster och då mer specifikt designtjänster. Slutligen belyses personliga kompetenser som minst lika viktiga komponenter.The swedish bachelor to become a garden designer includes courses such as business administration and marketing, which could encourage students to start their own business. Becoming self-employed might be the way to go but we ask ourselves if the training provides enough skills to dare to take that step. The bachelor thesis provides insight into the realities of entrepreneurs in garden design. The aim in this thesis is to investigate whether there are any specific components needed for starting and running a business in garden design. The essay should also try to establish which of these components are most important. The issue addressed in this paper is: Which are the key components to start and run a business in garden design? The thesis includes a literature review where existing research are presented. Here is described different ways to choose business organization and what it means to run a service business. Then there is mentioned key elements of the business plan, these concerns marketing, analysis of the market, branding and pricing. The literature review concludes by explaining what makes a company in garden design unique but also the importance of a variety of other skills. This part is followed by qualitative interviews whose aim is to contribute a reality. Four companies operating in garden design has been analyzed and then compared with the literature. The final discussion addresses how well they comply. It turns out that the interviewed companies do not equally apply those parts that literature describes and proposes. Only in some cases, the companies interviewed wrote some kind of document which can be likened to a business plan. The companies interviewed, however differently affected parts from a business plan without really thinking about it. Despite the lack of a business plan written down, the companies interviewed in this work succeeded in their business, which means we can question the need for such a thing. Marketing, branding, market research and pricing still stands up as important components for success as an entrepreneur in the industry. Another component is the knowledge of what it means to sell services and then more specifically design services. Finally there is a lot of personal competencies that are equally important

More control than support : populism, the Covid-19 pandemic, and media policies in USA, Brazil, Serbia, and Poland

The article examines the approach to media policy and regulation adopted during the COVID-19 pandemic in four countries that were led by populist leaders at the beginning of the pandemic: Brazil, the United States, Poland, and Serbia. We draw on an extensive analysis of legal, policy and related documents, as well as 63 interviews with key actors involved in pandemic communication, including government officials, health experts, and journalists. The study identifies the distinguishing features of populist policymaking as well as develops an original analytical framework for its analysis. We conclude that the media policies examined oscillated between control and support. On the one hand, several policies were aimed at controlling pandemic communications and limiting journalists’ access to public information; on the other hand, efforts were also made to support the media. On the whole, the drive to control overshadowed the efforts to provide support, and even when support was provided, it was often distributed in an untransparent or unfair manner that benefitted progovernment outlets. Arguably, this dynamic of control over support reflects the characteristic features of populist policymaking, especially its tendency to mobilize media policy in a manner that benefits progovernment outlets while minimizing opportunities for criticism

Pandemic communication in times of populism : politicization and the COVID communication process in Brazil, Poland, Serbia and the United States

This paper explores patterns of communication during the COVID-19 pandemic in four countries with right-wing populist governments during that period, Brazil, Poland, Serbia and the United States, based on interviews with key actors involved in that process. We look at a number of characteristics normally associated with populist rule and political culture likely to affect pandemic communication, including polarization, cultural populism hostile to expertise, personalized rule and machismo, the performance of crisis, and illiberalism. We find that many of these characteristics can be seen in patterns of pandemic communication across the four countries, but also find significant differences in the response of populist leaders between the U.S. and Brazil, on one hand, and Poland and Serbia on the other. Differences can be linked to different varieties of populism in the four countries and specifically their commitment to libertarian or more statist approaches, which also inform disparate public health policies, as well as to different levels of entrenchment of populists in positions of power. We conclude by discussing the politicization of public health and the lessons of the COVID pandemic for emergency risk communication in the era of populism
