Characterizing the work statistics of driven complex quantum systems is generally challenging because of the exponential growth with the system size of the number of transitions involved between different energy levels. We consider the quantum work distribution associated with the driving of chaotic quantum systems described by random matrix Hamiltonians and characterize exactly the work statistics associated with a sudden quench for arbitrary temperature and system size. Knowledge of the work statistics yields the Loschmidt echo dynamics of an entangled state between two copies of the system of interest, the thermofield double state. This echo dynamics is dictated by the spectral form factor. We discuss its relation to frame potentials and its use to assess information scrambling. [less ▲]

A workflow and toolchain proposal for analyzing users’ perceptions in cyber threat intelligence sharing platforms

Cyber Threat Intelligence (CTI) sharing platforms are valuable tools in cybersecurity. However, despite the fact that effective CTI exchange highly depends on human aspects, cyber behavior in CTI sharing platforms has been notably less investigated by the security research community. Motivated by this research gap, we ground our work in the concrete challenge of understanding users’ perceptions of information sharing in CTI platforms. To this end, we propose a conceptual workflow and toolchain that would seek to verify whether users have an accurate comprehension of how far information travels when shared in a CTI sharing platform. We contextualize our concept within MISP as a use case, and discuss the benefits of our socio-technical approach as a potential tool for security analysis, simulation, or education/training support. We conclude with a brief outline of future work that would seek to evaluate and validate the proposed model. [less ▲]

Workforce Transitions and Social Connectedness Among Older Adults in the United States

As the industrialized world faces a rapidly aging population, it has become increasingly important to understand the factors that influence the well-being of older persons. In this regard, many scholars have emphasized the importance of social connectedness. Various theories seek to explain social connectedness in later life, particularly as it applies to workforce involvement. Among those theories, we engage the theories of activity-substitution and of complementarity, and we seek to discover which provides a better account of the social and work lives of older Americans. We do so through an analysis of the first 2 waves (Wave 1: 2005–2006, Wave 2: 2010–2011) of the National Social Life, Health, and Aging Project (NSHAP). Workforce transitions over time are assessed for their impact on 3 social connectedness outcomes: expansiveness of close networks, overall friendship network, and social participation. Results provide strong support for the theory of activity-substitution. Furthermore, our results show that those re-entering paid work after some time out of the workforce show the largest changes in social connectedness. The present study reinforces the importance of studying social connectedness as a multidimensional concept and draws attention to the increasing variability in workforce participation patterns among older persons.

The COVID-19 took by surprise most Member States of the European Union, as they underestimated the rapid spread of the contagion in the continent. The response of the Member States was asymmetrical, individualistic and significantly slow. The first measures taken were to close down the internal borders. The response of the European Union was even slower to the point that and it was not until March 17th 2020 that the external borders were closed. These actions affected legal migration into the European Union from four perspectives: 1) it affected the mobility of those third country nationals who were on temporary stay in the Member States; 2) the entry of third country nationals to do seasonal work; 3) the entry and stay of legal migrants; and 4) the status quo of the third country nationals already residing in the Member States, especially those who have a loss of income. This article will deal with the measures taken by Member States on who to manage the immigration services during the crisis as well as the measures taken in order to deal with overstayers, seasonal workers and other legal migrants. Finally, we will focus in the vulnerable situation that third-country national salaried workers are exposed due to the loss of income or loss of employment in the Member States and the risk of being returned to their country of origin.
