Acute Crisis

Acute crisis events ranging from natural disasters to terrorist incidents now tend to generate an almost immediate response from social media users. This is especially pronounced on Twitter, due to that platform’s specific affordances as a particularly open and real-time medium. While analyses of such events have increased over recent years, we still understand relatively little about the way in which audiovisual materials relating to such crises are circulated and what they contribute to processes of witnessing. This is important, however, in an increasingly visual age when audiovisual material tends to be more widely viewed and shared than plain-text updates, and thus has a greater potential to influence viewers’ interpretations of an event. To address this gap in our understanding, this article investigates the distribution dynamics of audiovisual content on Twitter in the immediate aftermath of terror attacks in Paris and Brussels. Results point to the importance of broadening conceptualisations of conflict-related visuals and the ongoing relevance of affective content in such material. Furthermore, this article argues that contexts of time and space are crucial to consider, as is the role that individual actors – both human and non-human – play in disseminating such content.

The World

In today's world, critical infrastructure encompasses facilities vital to the economy, politics, and population. Their maintenance and safe operation can ensure the supply for the population. These facilities are at risk due to climate change, natural disasters, terror attacks, or wars which are increasingly affecting countries around the world. In addition, the human factor can also cause uncertainty and damages. The function of the world depends on human activities. In this chapter the uncertainties in safety and security are introduced. Security is the most important part as it is the critical infrastructure protection and human safety . The important pillars of safety and security and these uncertainties are introduced in this chapter.

Price Discovery Process

<p>In this paper we analyse and show how price discovery process influence the volatility of stocks. Using a theoretical approach, our initial analysis revealed that stocks experience ‘normal’ volatility as the price move from one equilibrium price to another as part of the price discovery process. Our further analysis revealed that, due to the inefficiency of financial markets, stocks also experience transitionary volatility which occurs when the price transition from one equilibrium price to another. The implication of these analytical findings means that the price discovery volatility effects can only be reduced by improving the efficiency of financial markets. Thus, we recommended that the financial microstructure be designed in a manner that promotes the efficiency of financial markets.      </p>

Natural disasters occur infrequently in Europe, but the spate of transportation, crowd and other disasters in the late 1980s challenged our collective denial of potential catastrophe. Greater attention is now given also to the frequent small-scale traumatic events which are just as devastating to the many people affected by them, such as violent assaults and road accidents.

Acquisition Speed

Speed is a salient feature of modern financial markets. This paper studies investors’ speed acquisition together with their information acquisition. Speed heterogeneity arises in equilibrium, fragmenting the information aggregation process with a nonmonotone impact on price informativeness. Various competition effects drive speed and information to be either substitutes or complements. The model cautions the possible dysfunction of price discovery: An improving information technology might complement speed acquisition, which shifts the concentration of price discovery over time, possibly hurting price informativeness. Novel predictions are discussed regarding investor composition and their investment performance. This paper was accepted by Gustavo Manso, finance.

Journalists are not immune from the emotional impact of their work as they report on mass shootings, terror attacks, and natural disasters. Adding to an established body of research on the interrelationship between journalism and trauma, this syndicate focused on how journalism schools should prepare students to deal with traumatic news content and events that would undoubtedly form part of their future day-to-day activities.

Option Market

The efficiency of the financial markets is important as it ensures increased productive efficiency and economic growth through better capital allocation. Price discovery is the central aspect of financial markets. The relatively efficient price signals also facilitate the participation of uninformed investors to make suitable portfolio choices. Derivative instruments like option contracts enhance informational efficiency of the underlying's market through better price discovery as these securities are expected to increase the flow of information in the market. Besides, they facilitate hedging of risk. In India, exchange-trade derivates are of recent origin in the stock market. This study investigates the significance of net open interest and trading volume in stock option and stock index option market to predict the underlying stock prices⁄index level. In the study, only 15 stock option contracts (having maturity of one-month) and Nifty options for the entire period, i.e., November 10, 2001 to November 2, 2004, have been analysed. The analysis could not be carried out for all the stocks in option segment because of the fact that the options were not traded or the trading range and volumes were too thin to justify any analysis. The major findings of the study are as follows: Net open interest of stock option is one of the significant variables in the determination of the future spot price of the underlying stock. Open interest-based predictors are statistically more significant than the volume-based predictors in the Indian context too as is the case for the US market. The trading behaviour of Indian investors is found to be different from their counterparts in the developed world. This difference can be attributed to: the nascent state of derivatives market in India extremely limited participation of institutional investors in the Indian stock derivative market because of regulatory restrictions; as such investors are allowed to use derivative securities mainly for hedging and arbitrage purposes only. The findings would definitely help the regulatory bodies in policy-making and further strengthening the efforts to promote the derivative market in India. There are many areas which are still unexplored and can be addressed by the future studies by using the intraday data and a larger sample for the stock options.
