Study Objectives: To evaluate the effects of total and partial sleep deprivation on reflection
impulsivity and risk-taking in tasks requiring deliberative decision-making processes.
Participants and Methods: Seventy-four healthy young adults were selected to participate
in two independent experiments, each consisting of a crossover design. In Experiment 1, 32
participants were tested after one night of regular sleep (RS), and after one night of total
sleep deprivation (TSD). In Experiment 2, 42 participants were tested following five nights

Divergent thinking involves the ability to find many different and new responses or solutions to open-ended problems. The ability to think divergently has been associated with different cognitive processes, including intuitive and rational thinking styles. However, research has not specifically addressed the extent to which divergent thinking is associated to decision-making styles, which involve habits to react in a certain way in specific decisional contexts.

The growing inadequacy of traditional ‘management toolkits’ for dealing with ever more complex phenomena highlights the need for a rethinking of consolidated management approaches: it is necessary a paradigmatic change for

Data interoperability refers to the issue of accessing and processing data from multiple sources in order to create more holistic and contextual information for improving data analysis, for better decision-making, and for accountability purposes. In the era towards a data-driven society, the notion of data interoperability is of paramount importance. Looking at the research work in the last decades, several types of data interoperability scenarios emerged, including the following.

The way that we describe and understand cities is radically transforming—just like the tools we use for designing and implementing them. The change is often seen only as a technological aspect, for example, in the concept of smart cities. Smart cities are believed to provide societies with a higher quality of life thanks to modern technologies. However, there is also a human factor that is needed to make these changes go smoothly: acceptance. For many, change and innovation cause fear and disrupt everyday habits.

During decisions, animals balance goal achievement and effort management. Despite physical exercise and fatigue significantly affecting the levels of effort that an animal exerts to obtain a reward, their role in effort-based choice and the underlying neurochemistry are incompletely known. In particular, it is unclear whether fatigue influences decision (cost-benefit) strategies flexibly or only post-decision action execution and learning.

Software Defined Networking (SDN) is a recent network architecture based on the separation of forwarding functions from network logic, and provides high flexibility in the management of the network. In this paper, we show how an attacker can exploit SDN programmability to obtain detailed knowledge about the network behaviour. In particular, we introduce a novel attack, named Know Your Enemy (KYE), which allows an attacker to gather vital information about the configuration of the network.

Purpose: The World Health Organisation estimates that 92 per cent of the world’s population does not have access to clean air. The World Bank in 2013 estimated that only air pollution (AP) was responsible for a $225bn cost in lost productivity. The purpose of this paper is to contribute to the current scholarly debate on the value of Big Data for effective healthcare management. Its focus on cardiovascular disease (CVD) in developing countries, a major cause of disability and premature death and a subject of increasing research in recent years, makes this research particularly valuable.
