Purpose This study aims to understand the relationship between politics and pandemics in shaping the characteristics and themes of people’s Tweets during the US 2020 presidential election. Additionally, the purpose is to detect misinformation and extremism, not only to help online social networks (OSN) to target such content more rapidly but also to provide a close to real-time picture of trending topics, misinformation, and extremism flowing on OSN. This could help authorities to identify the intents behind them and find out how and when they should address such content. Design/methodology/approach This study focuses on extracting and verifying knowledge from large-scale OSN data, at the intersection of the Coronavirus pandemic and the US 2020 presidential election. More specifically, this study makes manual, statistical and automatic inferences and extracts knowledge from over a million Tweets related to the two aforementioned major events. On the other hand, disinformation operations intensified in 2020 with the coincidence of the Coronavirus pandemic and presidential election. This study applies machine learning to detect misinformation and extreme opinions on OSN. Over one million Tweets have been collected by our server in real-time from the beginning of April 2020 to the end of January 2021, using six keywords, namely, Covid, Corona, Trump, Biden, Democrats and Republicans. These Tweets are inspected with regard to their topics, opinions, news, and political affiliation, along with misinformation and extremism. Findings Our analyses showed that the majority of these Tweets concern death tolls, testing, mask, drugs, vaccine, and travel bans. The second concern among these Tweets is reopening the economy and schools, unemployment, and stimulus bills. The third concern is related to the Coronavirus pandemic’s impacts on politics, voting, and misinformation. This highlights the topics that US voters on Twitter were most concerned about during this time period, among the multitude of other topics that politicians and news media were reporting or discussing. Automatic classification of these Tweets using a long short-term memory network revealed that Tweets containing misinformation formed between 0.5% and 1.1% of Coronavirus-related Tweets every month and Tweets containing extreme opinions formed between 0.5% and 3.1% of them every month, with its pick in October 2020, coinciding with the US presidential election month. Originality/value The originality of this study lies in establishing a framework to collect, process, and classify OSN data to detect misinformation and extremism and to provide a close to real-time picture of trending topics, misinformation, and extremism flowing on OSN.

Purpose Since the 2016 presidential election, hyper-partisanship has become a regular facet of the political landscape with Democrats and Republicans in increasing conflict. The purpose of this paper is to determine if perception of government sources related to trust and credibility has changed since the 2016 election and if the experiences and strategies of librarians who teach or consult about government information has changed in response to this environment. Design/methodology/approach A 24-question survey was distributed to garner qualitative and quantitative responses from librarians who teach or consult about government information in an academic environment. A total of 122 responses were used for analysis. Findings Academic librarians are seeing more concern from patrons about disappearing online government information and wider distrust of government information. Librarians also noticed that the political leanings of students color their perspective around government sources and that librarians also need to keep their political beliefs in check. Respondents emphasized a need for more government literacy and information literacy topics when discussing evaluation of government sources. Research limitations/implications The data collection only included responses from academic librarians. Further research could include in-depth interviews and look at experiences in various library types. Originality/value With the timeliness of this topic, there has not been an in-depth investigation into how the Trump administration has changed user trust and perception of government sources from the librarian’s point of view. This paper continues the conversation about how librarians can address the growing distrust of government information and give us insight into the effects of a turbulent political climate on government sources.

A manual content analysis compares 6019 Twitter comments from six countries during the 2016 US presidential election. Twitter comments were positive about Trump and negative about Clinton in Russia, the US and also in India and China. In the UK and Brazil, Twitter comments were largely negative about both candidates. Twitter sources for Clinton comments were more frequently from journalists and news companies, and still more negative than positive in tone. Topics on Twitter varied from those in mainstream news media. This foundational study expands communications research on social media, as well as political communications and international distinctions.

Purpose Previous dynamic prediction models rarely handle multi-period data with different intervals, and the large-scale patient hospital records are not effectively used to improve the prediction performance. This paper aims to focus on the prediction of cardiovascular disease using the improved long short-term memory (LSTM) model. Design/methodology/approach A new model based on the traditional LSTM was proposed to predict cardiovascular disease. The irregular time interval is smoothed to obtain the time parameter vector, and it is used as the input of the forgetting gate of LSTM to overcome the prediction obstacle caused by the irregular time interval. Findings The experimental results show that the dynamic prediction model proposed in this paper obtained a significant better classification performance compared with the traditional LSTM model. Originality/value In this paper, the authors improved the LSTM by smoothing the irregular time between different medical stages of the patient to obtain the temporal feature vector.

Subject The implications for Japan of the US presidential election. Significance US presidential election campaign rhetoric has sparked serious concerns in Japan about Washington's commitment to the East Asia region in the context of a long-term rise in geopolitical tensions. Republican candidate Donald Trump has publicly questioned the value of the US-Japan alliance, while Democratic Party candidate Hillary Clinton has muted her previous support for the Trans-Pacific Partnership (TPP) trade agreement, seen as the economic component of the US 'rebalance' to Asia under President Barack Obama's administration. Impacts Doubts about the US commitment to the region work to Beijing's advantage. The US government's likely failure to ratify the TPP will damage perceptions of Washington's commitment to the region. Though occasionally mooted, the idea of developing nuclear weapons is a non-starter in Japan.

The Relationship

Significance Several recent strains in the relationship guaranteed a tense official dialogue and tepid reception of Xi across Washington -- the impact of China's economic slowdown on the US stock market, accusations of Chinese cyber theft of US government workers' personal data, and continued maritime tensions. Impacts China's climate change commitments will improve its international image, but will not reduce tensions on other issues. Washington will impose sanctions if it believes China is breaking the new cybercrime agreement. US politics ahead of next year's presidential election will put more strain on China-US relations. Dialogue on the South China Sea is unlikely to bear fruit while Washington's policy is undecided.

Subject Political outlook for the Central African Republic. Significance The Constitutional Court yesterday ruled that the second-round presidential election -- scheduled for January 31 -- will go ahead. The court also annulled legislative polls held at the same time as the first round of the presidential election, citing numerous irregularities. The new leader will have greater political clout than the oft-criticised interim president, Catherine Samba-Panza, but faces difficulties healing sectarian rifts and rebuilding institutions following the two-year civil conflict. Impacts Re-running the legislative polls will prove costly, stretching already strained donor and government budgets. Exports of rough diamonds from CAR will continue to be banned by the Kimberley Process until governance standards improve. Mass displacement coupled with irregular weather patterns will disrupt the agricultural cycle, creating a large-scale food security crisis. IMF, United Nations and other agencies will help the incoming administration to draft a development programme, given weak state capacity.

Repurchase Agreements

Subject Quantitative easing and GDP. Significance The US Federal Reserve (Fed), Bank of Japan (BoJ) and ECB have all conducted quantitative easing (QE) programmes since 2008, purchasing assets from commercial banks on a large scale and without predefined repurchase agreements. These purchases have swollen the balance sheets of the three largest central banks and provided commercial banks with large liquidity buffers. Impacts The pace of the Fed withdrawing liquidity may slow; if US-China conflict worsens or another shock occurs, the Fed may consider reversing. In the euro-area, there are no new liquidity provisions, at a time when German GDP is weakening and Brexit threatens EU growth. New liquidity-provision plans may be hard for the euro-area to agree; if this is off the table, so are liquidity-withdrawing measures. The BoJ may stop scaling back its bond and ETF holdings if markets suffer; the upcoming sales tax rise will also hit spending.

Subject Indonesia's economic headwinds. Significance Finance Minister Sri Mulyani Indrawati last week said the US Federal Reserve (Fed) should be careful about how its policies affect emerging markets. Tightening US monetary policy and a global trend of trade protectionism is straining Indonesia’s currency and current account deficit. President Joko ‘Jokowi’ Widodo will be eager to demonstrate that he can handle Indonesia’s economic challenges ahead of the presidential election in April 2019. Impacts Sri Mulyani’s message to the Fed is unlikely to have much traction in Washington. The force of economic nationalism will hinder Indonesia’s efforts to court more foreign direct investment. US trade reprisals on Indonesia would damage Washington-Jakarta diplomatic ties.

Significance He leaves office having failed to achieve his ambition to reform Japan’s constitution, and is widely seen as having mismanaged the most serious public health crisis in decades. Impacts New foreign policy initiatives are unlikely until after the US presidential election. Abe could make a decision before leaving office on whether Japan should acquire pre-emptive strike capabilities. No moves on constitution revision are likely for the next twelve months at least. Japan would be at a disadvantage if a foreign policy crisis were to occur in the next twelve months, and the next few weeks in particular. Whether the Olympics next summer go well will have some influence on whether Suga stays on as leader.

Significance However, Republican President Donald Trump is alleging that vote tallies are fraudulent and inaccurate. He is seeking recounts and undertaking lawsuits over alleged vote-counting irregularities. Impacts Two run-off elections in Georgia will determine whether the US Senate stays Republican or is tied 50-50 with the Democrats. Given the type of complaints raised by Trump’s campaign, prospects for a Supreme Court intervention look remote. Controversy over the election result will linger, perhaps until the 2024 presidential election.
