Tendon Tension

Hurricane Lili permitted an assessment of the global performance of several deepwater structures under a major environmental event. The US Minerals Management Service (MMS) commissioned American Global Maritime Inc. (AGMI) to collect and assess information on the performance of the deepwater production facilities that were impacted by Lili. The Shell Brutus Tension Leg Platform (TLP) provided comprehensive measurements of winds, motions and tendon tensions during Lili. The tendon tension data recorded was analyzed in both the time and frequency domain and tendon tension statistics were comparable to the relevant design values. Other relevant comparisons included natural period and damping estimates. Overall the design ‘recipe’ adopted for Brutus was sufficient to prevent exceedance of design capacities and damage to the hull structure and tendons during Hurricane Lili. The lessons learned from the analyses and recommendations for further work are also summarized in this paper.

Psychodynamic Understanding

This article aims to advance the psychodynamic understanding of imagination failures by studying lessons learned in the US government’s public inquiry into September 11th, 2001 (9/11). Analyzing the findings of The 9/11 Report, I theorize that two forms of macro-level hubris—America’s “hubris of empire-building” and Al Qaeda’s “hubris-nemesis complex”—amalgamated in a uniquely generative manner leading to events on 9/11. Previous studies of public inquiries often demonstrate that inquiry reports are monological story-telling performances used to create sense-making narratives that function hegemonically to impose a simplified version of reality to assign blame and depoliticize events in order to facilitate closure after shocking events. In contrast, findings here suggest that by constructing a critical narrative, The 9/11 Report may serve as a new type of public inquiry report that invites learning about the complex factors that underpin crisis. The article concludes by identifying fruitful areas of future research and ways to theorize further about the collective psychodynamics of macro-level hubris and the psychodynamic factors that hinder learning and contribute to imagination failures.

Terrorism and violent extremism have undoubtedly become among the top security concerns of the 21st century. Despite a robust agenda of counterterrorism since the September 11, 2001 attacks, the evolution of global terrorism has continued to outpace the policy responses that have tried to address it. Recent trends such as the foreign fighter phenomenon, the rampant spread of extremist ideologies online and within communities, and a dramatic increase in terrorist incidents worldwide, have led to a recognition that “traditional” counterterrorism efforts are insufficient and ineffective in combatting these phenomena. Consequently, the focus of policy and practice has shifted towards countering violent extremism by addressing the drivers of radicalization to curb recruitment to extremist groups. Within this context, the field of countering violent extremism (CVE) has garnered attention from both the academic and policy-making worlds. While the CVE field holds promise as a significant development in counterterrorism, its policy and practice are complicated by several challenges that undermine the success of its initiatives. Building resilience to violent extremism is continuously challenged by an overly securitized narrative and unintended consequences of previous policies and practices, including divisive social undercurrents like Islamophobia, xenophobia, and far-right sentiments. These by-products make it increasingly difficult to mobilize a whole of society response that is so critical to the success and sustainability of CVE initiatives. This research project addresses these policy challenges by drawing on the CVE strategies of Canada, the US, the UK, and Denmark to collect best practice and lessons learned in order to outline a way forward.

SEAD – a project funded by the US National Science Foundation’s DataNet program – has spent the last five years designing, building, and deploying an integrated set of services to better connect scientists’ research workflows to data publication and preservation activities. Throughout the project, SEAD has promoted the concept and practice of “active curation,” which consists of capturing data and metadata early and refining it throughout the data life cycle. In promoting active curation, our team saw an opportunity to develop tools that would help scientists better manage data for their own use, improve team coordination around data, implement practices that would serve the data better over time, and seamlessly connect with data repositories to ease the burden of sharing and publishing. SEAD has worked with 30 projects, dozens of researchers, and hundreds of thousands of files, providing us with ample opportunities to learn about data and metadata, integrating with researchers’ workflows, and building tools and services for data. In this paper, we discuss the lessons we have learned and suggest how this might guide future data infrastructure development efforts.

Epidemic Response

In this follow-up panel, we discuss what we have learned over the last year about responding to an epidemic or pandemic that has demonstrated a level of transmission unprecedented in the modern era. Two medical doctors that have worked on the front of this pandemic share their experiences transitioning from the “sharp end” of the response. Decisions about how to mitigate hazards have occurred at the personal, institutional, and health policy levels, in real-time, with frequent adaptation, and often in advance of concrete evidence. Over the course of the pandemic, hospital systems revised existing protocols to manage perceived risks in real time using emerging information from other centers. With the introduction of vaccines, there is a new type of risk perception. Is the vaccine perceived to be safe? Is there a disparity in perception among different population groups? That said, analyses are also complicated by emerging viral mutations with unclear implications. What factors increase or decrease public compliance with precautions? How are US education policymakers deciding about face-to-face classroom instruction? This panel includes a warnings expert, an expert on education policy, and two practicing physicians.

The US CDC has recognized moist-heat as one of the most effective and accessible methods of decontaminating N95 masks for reuse in response to the persistent N95 mask shortages caused by the COVID-19 pandemic. However, it is challenging to reliably deploy this technique in healthcare settings due to a lack of smart technologies capable of ensuring proper decontamination conditions of hundreds of masks simultaneously. To tackle these challenges, we developed an open-source wireless sensor platform---VeriMask1 ---that facilitates per-mask verification of the moist-heat decontamination process. VeriMask is capable of monitoring hundreds of masks simultaneously in commercially available heating systems and provides a novel throughput-maximization functionality to help operators optimize the decontamination settings. We evaluate VeriMask in laboratory and real-scenario clinical settings and find that it effectively detects decontamination failures and operator errors in multiple settings and increases the mask decontamination throughput. Our easy-to-use, low-power, low-cost, scalable platform integrates with existing hospital protocols and equipment, and can be broadly deployed in under-resourced facilities to protect front-line healthcare workers by lowering their risk of infection from reused N95 masks. We also memorialize the design challenges, guidelines, and lessons learned from developing and deploying VeriMask during the COVID-19 Pandemic. Our hope is that by reflecting and reporting on this design experience, technologists and front-line health workers will be better prepared to collaborate for future pandemics, regarding mask decontamination, but also other forms of crisis tech.

This chapter summarizes the lessons learned about Homo Suffragator and the psychology of voters. Do personality, memory, and identity shape citizens' electoral experience and behaviour, and elections' capacity to bring democratic resolution; and what are the main determinants of each model? Has the book's attempt to turn electoral science upside-down by switching the dependent variable been successful? It may be of greater consequence to know whether elections make people happy, and whether they offer a continuous peaceful resolution to divergent preferences and beliefs, than to know whom people and nations vote for. Beyond summarizing the results of the static models explored so far, the chapter also reintegrates the original dynamic expectations into the model, and assesses the reciprocal causality between the three interrelated dependent variable sets—behaviour, experience, and resolution—using the panel study design in the US case.
