Two workshops were part of the final steps in the Economic and Social Research Council (ESRC) commissioned Ways of Being in a Digital Age project that is the basis for this Handbook. The ESRC project team coordinated one with the UK Defence Science and Technology Laboratory (ESRC-DSTL) Workshop, “The automation of future roles”; and one with the US National Science Foundation (ESRC-NSF) Workshop, “Changing work, changing lives in the new technological world.” Both workshops sought to explore the key future social science research questions arising for ever greater levels of automation, use of artificial intelligence, and the augmentation of human activity. Participants represented a wide range of disciplinary, professional, government, and nonprofit expertise. This chapter summarizes the separate and then integrated results. First, it summarizes the central social and economic context, the method and project context, and some basic definitional issues. It then identifies 11 priority areas needing further research work that emerged from the intense interactions, discussions, debates, clustering analyses, and integration activities during and after the two workshops. Throughout, it summarizes how subcategories of issues within each cluster relate to central issues (e.g., from users to global to methods) and levels of impacts (from wider social to community and organizational to individual experiences and understandings). Subsections briefly describe each of these 11 areas and their cross-cutting issues and levels. Finally, it provides a detailed Appendix of all the areas, subareas, and their specific questions.

Operational Aspects

A limited number of studies in the scientific literature discuss the “Build-Back-Better” (BBB) critical infrastructure (CI) concept. Investigations of its operational aspects and its efficient implementation are even rarer. The term “Better” in BBB is often confusing to practitioners and leads to unclear and non-uniform objectives for guiding accurate decision-making. In an attempt to fill these gaps, this study offers a conceptual analysis of BBB’s operational aspects by examining the term “Better”. In its methodological approach, this study evaluates the state of Saint-Martin’s CI before and after Hurricane Irma and, accordingly, reveals the indicators to assess during reconstruction projects. The proposed methods offer practitioners a guidance tool for planning efficient BBB CI projects or for evaluating ongoing programs through the established BBB evaluation grid. Key findings of the study offer insights and a new conceptual equation of the BBB CI by revealing the holistic and interdisciplinary connotations behind the term “Better” CI: “Build-Back-resilient”, “Build-Back-sustainable”, and “Build-Back-accessible to all and upgraded CI”. The proposed explanations can facilitate the efficient application of BBB for CI by operators, stakeholders, and practitioners and can help them to contextualize the term “Better” with respect to their area and its CI systems.

To legitimize US invasion of Iraq, Bush fabricated fake intelligence reports, and depended solely on propaganda; he manipulated language in a well-calculated manner; most particularly, the metaphors chosen and devised for his speeches were such that convinced the US citizens about the legitimacy of the invasion, elicited financial support of the European allies and moral support of the majority of the world community. This research work used discourse analysis to study the metaphors that were used by George Bush in the speeches he made on 8 different occasions, and the theoretical framework used in it is the combination of critical discourse analysis CDA with postcolonial theory concept of orientalism.It utilized both qualitative and quantitative data collection tools.It found that most of the task was accomplished through the linguistic manipulation in the shape of metaphor used to dehumanize the enemy, which first made the US citizens feel as victims to the jealousy of rogue Muslim states for intending to completely annihilate them; then, it made appeal to their sense of justice, sense of security, and right to self-defense. By grouping the world citizens into Us and Them groups, the innocent, peace-loving and the war-mongers, the angels and the devils, and then by placing themselves and the rest of the world among the first group and placing the powerfulMuslims states among the second group, the US exploited the feelings and thoughts of all. Despite the UN and the rest of the world having come to know the sheer lies of the US now, the US still has managed to flog a dead horse and blind-fold majority of the world through this linguistic manipulation in the form of using dehumanizing metaphors

Chapter 6 focuses on debate over the crucial issue of liability in India and the emergence of liability legislation that has prevented the operationalization of the nuclear deal and negated euphoric predictions by US businesses that the deal would create thousands of hi-tech jobs in the US through the sale of nuclear reactors to India. The memories of the Bhopal disaster and residual suspicions of the US amongst the Indian polity gave rise to liability legislation that channelled liability to the suppliers of nuclear reactors, in variance with the prevailing norm of holding reactor operators responsible for accidents. The loud protests of American corporations that the liability law exposes them to unsustainable amounts of liability and the attempts of the Modi government to find a ‘workaround’ at the bureaucratic level have borne little fruit.

AbstractRecent events in the workplace, government, and college campuses in the US have brought the issues of sexual harassment and assault to the forefront of media and public discussion. Industrial and organizational (I-O) psychologists are uniquely suited to help address these issues by aiding in intervention development. Specifically, I-O psychologists can provide key insight regarding the context, design, development, and evaluation of sexual harassment and assault training efforts. Although some empirical evidence suggests that trainings are effective in the short term, there is little evidence to suggest long-term attitudinal or behavioral change outside of the training environment. Much of the research in this area, however, has focused solely on the training intervention, excluding the pre- and post-training environment. Thus, the present effort focuses on designing trainings that promote transfer, as well as improving measurement of desired outcomes, to provide a framework for improving sexual harassment and assault training. This framework addresses how individual differences, needs analysis, training design, evaluation, and post-training support contribute to lasting change while addressing the unique challenges associated with sexual harassment and assault. Last, this framework provides guidance for improving research in this area as well as practical suggestions for improving training programs.

Energy Information

The used fuel inventory of the United States commercial nuclear fleet has been accumulating since the inception of nuclear reactors. In order to understand the mass and composition of the used fuel inventory, a nuclear fuel cycle simulation package (Cyclus) is used with a reactor modeling tool (Bright-lite). The parameters for the simulation are obtained as historical operation and burnup data for every reactor in the US fleet, taken from the U.S. Energy Information Administration. The historical burnup data is used to calculate the fuel enrichment of every reactor at every refueling. Discharged uranium inventories calculated by the software are shown to closely match the reference data. The total mass of three major actinide groups are presented as they build up over time. In addition, the evolution of the plutonium composition in discharged fuel is also presented, illustrating Cyclus’ ability to track the composition of material flowing through a large, evolving reactor fleet over decades.

Abstract Cirrhosis is a liver disease that is considered to be among the most common diseases in healthcare. Due to its non-invasive nature, ultrasound (US) imaging is a widely accepted technology for the diagnosis of this disease. This research work proposed a method for discriminating the cirrhotic liver from normal liver through US images. The liver US images were obtained from the radiologist. The radiologist also specified the region of interest (ROI) from these images, and then the proposed method was applied to it. Two parameters were extracted from the US images through differences in intensity of neighboring pixels. Then, these parameters can be used to train a classifier by which cirrhotic region of test patient can be detected. A 2-D array was created by the difference in intensity of the neighboring pixels. From this array, two parameters were calculated. The decision was taken by checking these parameters. The validation of the proposed tool was done on 80 images of cirrhotic and 30 images of normal liver, and classification accuracy of 98.18% was achieved. The result was also verified by the radiologist. The results verified its possibility and applicability for high-performance cirrhotic liver discrimination.

Abstract. Despite its importance to a range of applied and fundamental studies, and obvious parallels to a robust network of magnetic-field observatories, long-term geoelectric field monitoring is rarely performed. The installation of a new geoelectric monitoring system at the Boulder magnetic observatory of the US Geological Survey is summarized. Data from the system are expected, among other things, to be used for testing and validating algorithms for mapping North American geoelectric fields. An example time series of recorded electric and magnetic fields during a modest magnetic storm is presented. Based on our experience, we additionally present operational aspects of a successful geoelectric field monitoring system.

The ANNETTE Project (Advanced Networking for Nuclear Education and Training and Transfer of Expertise) is well underway, and one of its work packages addresses the design, development and implementation of nuclear fusion training. A systematic approach is used that leads to the development of new training courses, based on identified nuclear competences needs of the work force of (future) fusion reactors and on the current availability of suitable training courses. From interaction with stakeholders involved in the ITER design and construction or the JET D-T campaign, it became clear that the lack of nuclear safety culture awareness already has an impact on current projects. Through the collaboration between the European education networks in fission (ENEN) and fusion (FuseNet) in the ANNETTE project, this project is well positioned to support the development of nuclear competences for ongoing and future fusion projects. Thereby it will make a clear contribution to the realization of fusion energy.

This paper was presented at the 44th Annual Meeting of the US Institute of Navigation in Annapolis, June 1988.Navigational systems are usually thought of in terms of locating vehicles and craft over a range of hundreds or thousands of miles. There are, however, applications where navigation systems with a range of a few miles and an accuracy of inches can be very useful. Farming is one of these applications and this paper identifies the specific operational aspects that can benefit. Precise navigation could facilitate a lowering of input costs by an estimated jo per cent on a western dryland farm.
