ABSTRACT Target date funds (TDFs) are becoming increasingly popular investment choices among investors with long-term prospects. Examples include members of superannuation funds seeking to save for retirement at a given age. TDFs provide efficient risk exposures to a diversified range of asset classes that dynamically match the risk profile of the investment payoff as the investors age. This is often achieved by making increasingly conservative asset allocations over time as the retirement date approaches. Such dynamically evolving allocation strategies for TDFs are often referred to as glide paths. We propose a systematic approach to the design of optimal TDF glide paths implied by retirement dates and risk preferences and construct the corresponding dynamic asset allocation strategy that delivers the optimal payoffs at minimal costs. The TDF strategies we propose are dynamic portfolios consisting of units of the growth-optimal portfolio (GP) and the risk-free asset. Here, the GP is often approximated by a well-diversified index of multiple risky assets. We backtest the TDF strategies with the historical returns of the S&P500 total return index serving as the GP approximation.

The European Air Traffic Management Network (EATMN) is comprised of various stakeholders and actors. Accordingly, the operations within EATMN are planned up to six months ahead of target date (tactical phase). However, stochastic events and the built-in operational flexibility (robustness), along with other factors, result in demand and capacity imbalances that lead to delayed flights. The size of the EATMN and its complexity challenge the prediction of the total network delay using analytical methods or optimization approaches. We face this challenge by proposing a deep convolutional neural network (DCNN), which takes capacity regulations as the input. DCNN architecture successfully improves the prediction results by 50 percent (compared to random forest as the baseline model). In fact, the trained model on 2016 and 2017 data is able to predict 2018 with a mean absolute percentage error of 22% and 14% for the delay and delayed traffic, respectively. This study presents a method to provide more accurate situational awareness, which is a must for the topic of network resiliency.

In the ancient past, much of East Asia and China was connected to different trading regions of the world through Silk Road. It got its name on the main export item of the then China: Silk. Now China has taken the initiative to rebuild the Silk Road through its OBOR initiative. OBOR has two components in the shape of two projects: over land SREB and a 21st century MSR. Later, merging these two projects under one canopy, OBOR has been termed as BRI of China. This study attempts to answer the research question: One Belt One Road Initiative (OBOR) of China as the primer to a new geo-strategic hegemony for building the competitive Chinese world order would stabilize? A content analysis was performed on pivotal media coverage about OBOR. Since the ever first speech of the President of China, Mr. Xi Jinping in 2013, a media debate is there, on this Chinese initiative. OBOR is an effort to increase the regional connectivity to embrace a China oriented future. For them, this brighter future in the shape of an economic move for Chinese domination in the global affairs, while being the centre of global trade network. China would be celebrating its hundredth anniversary in 2049 and this is exactly the target date of completing the OBOR. A keyword analysis yielded through the speeches of Chinese President Mr. Xi Jinping on the global media networks alongwith the messages conveying Chinese aspirations of its coming out as the global economic lynch pin by the new Chinese geo-strategic hegemony under the canopy of connectivity and cooperation is the pivot of these well telecasted speeches. Keywords: Geo-strategy, Chinese geo-strategic hegemony, competitive Chinese world order, foreign policy, economic pivot, maritime, overland, port projects, infrastructure, connectivity, people to people contact.
