Why politicians react to media coverage
Authors: Helfer Luzia , Van Aelst Peter 
Published: April 2020

Abstract
Why do politicians react to some stories in the news and ignore others? We attempt to answer this question by
integrating the micro-level politician perspective with a macro-level country approach. Using a unique experimental approach, we
test when politicians in the Netherlands and Switzerland (N = 80) take political action based on a (fictional)
news report. We find that all politicians react more to negative coverage, but not if the information is merely presented as
investigative reporting. Results also reveal a systematic variation that we ascribe to two key differences in the electoral
systems. In The Netherlands, with its large single voting district, politicians react to news reports covering issues they are
specialized in. In Switzerland, where between-party competition is more important, politicians are more likely to capitalize on
the party’s profile. Overall, this study shows when and how politicians react to news coverage also depends on the institutional
context.
Political actors’ access to the media agenda
Authors: Palau Anna M. , Ansemil Miquel 
Published: April 2020

Abstract
This article explores to what extent the euro crisis brought about unprecedented attention to the European Union (EU) and if so with what consequences on the media visibility of different political actors in Spain. Drawing on a database of more than 27,000 stories published in the most read Spanish newspaper from 2004 to 2012, we demonstrate that following the outbreak of the crisis, executive elites receive more media coverage than social movements, trade unions, and challenger parties critical with EU policies and decisions. The media coverage of EU affairs, however, is not business as usual. Executive elites receive disproportionate media attention but they are no longer presented using the EU following credit-claiming strategies. Our results also indicate that the media are not passive actors that respond to institutional determinants but might be actively involved in the process of giving some actors more visibility in public debates on EU affairs.
Pragmalinguistic challenges for trainee interpreters in achieving accuracy
Authors: Liu Xin 
Published: April 2020

Abstract
In cross-examination, questions are used by counsel as powerful tools to control witness testimonies. In bilingual
courtrooms, conveying the subtlety in the use of questions from one language to another is crucial for all participants. However,
achieving a high level of accuracy is extremely demanding due to the intricacy of courtroom discourse and the complexity of
interpreting in such an institutional setting. Drawing on a moot court exercise at the University of New South Wales, Sydney, this
study investigates the most common pragmalinguistic challenges for trainee interpreters in achieving accuracy when interpreting
cross-examination questions from English to Mandarin. Findings show that it can be challenging to produce pragmatically accurate
renditions: Mandarin interpretations have an overall weakened illocutionary force compared to the original English questions. In
particular, declaratives, reported speech declaratives, modal interrogatives, and tag questions are found to be difficult to
interpret into Mandarin. This paper also explores the way the illocutionary force of the interpreted questions deviates from the
original and the possible causes for this shift. Findings point to the need to enhance pragmatic competence among trainee
interpreters, which in turn will require specialised training for interpreters working in legal settings.
The role of task repetition with direct written corrective feedback in L2 writing complexity, accuracy and
fluency
Authors: Khezrlou Sima 
Published: April 2020

Abstract
This study explored whether the effects of task repetition in drawing learners’ attention to linguistic form could
be reinforced through the provision of two types of unfocused direct written corrective feedback. Fifty-seven learners formed
three conditions: (1) task repetition with no feedback (TR, control), (2) task repetition with error correction (TR+EC), and (3)
task repetition with reformulation (TR+R). All groups repeated an identical writing narrative task but only the experimental
groups received feedback after their initial task performance. All participants were then asked to complete a new task of the same
type followed by a new task of a different type. Performance was gauged by multiple measures of complexity, accuracy and fluency.
Results revealed the persistent superiority of the TR+EC condition on all measures of accuracy while the TR+R condition led to
immediate written complexity improvement regarding subordination. Furthermore, both the TR+R and TR conditions resulted in delayed
fluency gains.

Stance and modals of obligation and necessity in academic writing
Authors: Parkinson Jean 
Published: April 2020

Abstract
Variation has been demonstrated in modal use between written and spoken registers and between disciplines. This article investigates variation within a discipline by comparing modals of obligation and necessity used in three science genres. Obligation modals project strong authoritative stance, thus contrasting with the tendency in academic writing towards tentativeness. The modal auxiliaries must and should and quasi-modals have to and need to are investigated using student writing from the BAWE (British Academic Written English) corpus and a corpus of published research articles. Findings include a dearth of obligation modals in the empirical genres (research articles and laboratory reports). Also a greater prominence was found of dynamic modal meaning (where necessity arises from circumstances) rather than deontic meaning (where the necessity arises from human authority or rules). A further finding is the prominence of objective meaning in the science register compared with the International Corpus of English (Collins 2009a).

Authors: Chen Fan , Yao Weixin 
Published: April 2020

Abstract
Based on the impact of undesired output and the recycling characteristics of circular economy, this paper reconstructed the evaluation index of circular economy efficiency of Chinese provinces and cities, took the data of 10 provinces and cities in eastern China from 2011 to 2017 as the research object, and analyzed the efficiency of circular economy in eastern China by using the data envelopment analysis model. Research results show that: (1) From 2011 to 2017, the average efficiency of circular economy in 10 provinces and cities in eastern China was low, with serious two-level differentiation. From 2011 to 2015, the average efficiency of circular economy in all provinces and cities showed a slow downward trend, slightly recovered in 2016, and slightly declined in 2017.(2)In 2017, the pure technical efficiency of eastern China is high, but the scale efficiency is low. Therefore, Eastern China should first improve the scale efficiency, and then improve the pure technical efficiency. (3) In 2017, Tianjin, Jiangsu, Guangdong and Hainan focused on improving their scale efficiency, while Hebei, Zhejiang, Fujian and Shandong need to improve their pure technical efficiency and scale efficiency at the same time.

Published: April 2020

Abstract
Most converter valves of IGBT modules use a water-cooling system. The cooling technology of water cooling system is mature and has considerable advantages. However, higher power density power electronics lead to greater cooling power. With the improvement of the heat dissipation power of power electronic devices, the traditional water cooling system will gradually fail to meet the heat dissipation requirements of power electronic devices, and new cooling systems need to be developed. In this paper, based on the existing traditional water-cooling system model, numerical simulation analysis technology is used to compare and analyze the different cooling materials (copper, aluminum) and cooling medium (water, liquid metal) under the working conditions. For deionized water and liquid metal, the heat dissipation effect is compared and analyzed, which shows that the heat dissipation performance of the heat dissipation system using copper and liquid metal is greatly improved. Based on this, the model of liquid metal heat dissipation system is proposed. Compared with the traditional cooling model, it shows its superiority in heat dissipation performance with highest temperature decreased by 20.4%.

Authors: Li Hailong , Liu Ke , Tan Xiaodong 
Published: April 2020

Abstract
In this paper, two types of electric welding equipment are studied. First of all, YD / k-505fl4 and bx3-500 type welding machines do not have the function of self power off in standby state. It is necessary to install an intelligent welding machine power saving system to control the power off of the primary side of the transformer under the no-load state of the welding machine, and then cut off the no-load loss of the welding machine. Secondly, yd-500-kr II series welding machine has the function of standby, delay and self power off. Due to the unreasonable setting of welding parameters, the uneconomical selection of welding cable and the unreasonable layout of welding machine, the overall energy loss of welding machine is large. Finally, weathering steel is used in the welding process design, and the performance, energy consumption and economic practicability of the material are analyzed.

Abstract
In order to solve the problems in current power grid operation safety management field, the paper firstly distinguishes the concept definitions and forms the uniform standards by discriminating the basic concepts in safety management field. Then, the extension model is formed through standardizing the relationship between different terms by using Wayne diagram based on the set theory. Finally, a set of concept identification algorithm flow is proposed to help the identification of concepts in actual practices. The research shows that, from the perspective of accident causation, the safety management concepts can be divided into two categories. In terms of the causation, the accident potential belongs to the hazard of second kind and third kind which is included into the risk; in the results caused by the causation, the accident precursor includes the near-miss and the accident without intervention which are included into the incident.

This model could utilize the uncertain information of parameters sufficiently to acquire reliable and objective results.
Adsorption of Reactive Brilliant Red X-3B from Aqueous Solution by Polypyrrole/Calcium Rectorite Composites: Adsorption Behavior and Mechanism
Authors: Guo Qihua , Xu Yaolei , Yong Kun , Chen Ran , Wang Xiaofeng , Chen Jinyi 
Published: April 2020

Abstract
In this study, polypyrrole/calcium rectorite clay composites (PPy/REC composites) were prepared by in-situ polymerization of pyrrole monomer to adsorb reactive brilliant red X-3B from aqueous solution. The results of XRD showed that the clay flakes exfoliated in the prepared composites. The SEM results showed that PPy had good dispersibility on clay sheets. The adsorption mainly depended on the initial pH value of the solution, and the optimal adsorption of reactive brilliant red X-3B was achieved when the pH value was 2.0. The removal rate of PPy/REC composite was much higher than that of PPy homopolymer. The adsorption kinetic data of reactive brilliant red X-3B at three initial concentrations (100, 150 and 200 mg/L) were best fitted by the pseudo-second-order model, indicating that the concentration gradient of the adsorbent was the driving force of the adsorption process. The adsorption isotherm accorded with the Langmuir isotherm model, and the maximum adsorption capacity was 232.56 mg/g at 298 K. The PPy/REC composites could be regenerated and reused for 5 continuous adsorption-desorption cycles without losing the removal efficiency of the original reactive brilliant red X-3B. XPS, zeta potential and FT-IR results showed that the removal mechanism of reactive brilliant red X-3B was related to electrostatic interaction and ion exchange.

Abstract
Mg/Al-LDH was prepared by co precipitation method at pH 10.5, 85 and hot water °C for 6 hours with controlling Mg/Al ratio (2:1 and 3:1) and mixing (at common stirring and ultrasonic stirring). The samples were characterized by the Fourier transform infrared spectro scopy and X-ray diffractometer analysis. Finally, the four group structure and excellent quality of hydrotalcite materials were obtained. Samples were calcined at 500 for 4h, and then °C the effects of different influencing factors on the adsorption of alizarin red by the adsorbent were studied. The results show that the prepared materials are layered with hydrotalcite and have good adsorption performance. When the pH value is 10, adding 1g of hydrotalcite and performing adsorption at low temperature, the adsorption rate reaches a maximum of 99%.
