Who's Controlling Who? Personal Communication Devices and Work

Personal communication devices have long been part of work life. In recent decades, the range of modes available has proliferated and their use has became widespread. This article examines the ways that personal communication devices have shaped workers' experience of work. It reviews four key areas of research on this topic: the ability to work in new times and spaces; the relationship between work and personal life; the fragmentation of work; and the pace and intensity of work. The article highlights how the issue of control is critical when attempting to understand the how and why of any effects arising from workers' use of these technologies.     

Group Therapy for Emotional Dysregulation: Treatment for Adolescents and Their Parents

A dialectical behaviour therapy (DBT) group has been conducted for a number of years at a public outpatient clinic for adolescents suffering with emotional regulation difficulties and their families. A detailed account of the rationale, design, and content of both the adolescent and parent groups are provided. Data from these groups adds to the limited evidence regarding the efficacy of such groups. A retrospective analysis of changes in the adolescent participants’ emotional dysregulation, depression, anxiety and stress, following their participation in the group (N?=?12) was conducted. Several substantial improvements were noted across the measures of psychopathology, following the completion of the group. These findings support the teaching of DBT skills to adolescents and their families, with some modifications being appropriate for their application to this population. Future avenues for research stemming from the group program are also discussed.     

The Role of Behavioral Responses in the Total Economic Consequences of Terrorist Attacks on U.S. Air Travel Targets

U.S. airports and airliners are prime terrorist targets. Not only do the facilities and equipment represent high‐value assets, but the fear and dread that is spread by such attacks can have tremendous effects on the U.S. economy. This article presents the methodology, data, and estimates of the macroeconomic impacts stemming from behavioral responses to a simulated terrorist attack on a U.S. airport and on a domestic airliner. The analysis is based on risk‐perception surveys of these two scenarios. The responses relate to reduced demand for airline travel, shifts to other modes, spending on nontravel items, and savings of potential travel expenditures by U.S. resident passengers considering flying domestic routes. We translate these responses to individual spending categories and feed these direct impact results into a computable general equilibrium (CGE) model of the U.S. economy to ascertain the indirect and total impacts on both the airline industry and the economy as a whole. Overall, the estimated impacts on GDP of both types of attacks exceed $10B. We find that the behavioral economic impacts are almost an order of magnitude higher than the ordinary business interruption impacts for the airliner attack and nearly two orders of magnitude higher for the airport attack. The results are robust to sensitivity tests on the travel behavior of U.S. residents in response to terrorism.     

Ethnicity and place in a ‘disturbed city’: ways of belonging in Imphal,Manipur

This article explores the relationships between ethnicity, place and belonging in the city of Imphal, capital of the state of Manipur in India’s Northeast border region. Manipur has experienced decades of conflict from ethno-nationalist separatism, inter-ethnic territorial disputes and counter-insurgency operations. These ethnic conflicts play out on the urban landscape of Imphal. Control of the city from above is diffused among the civilian government and the armed forces. Non-state actors such as insurgent groups and ethnic organizations exert their own control from below. On such unstable ground, struggles by residents seeking to create place and a sense of belonging affirm ethnic boundaries. These boundaries are not static and the lines between inclusion and exclusion are continually redrawn along existing and emerging fault-lines among the population. Yet these boundaries are also transcended in unusual ways that may seem trivial but in Imphal are essential to realizing alternative ways of belonging.     

Quantifying the Hurricane Catastrophe Risk to Offshore Wind Power

The U.S. Department of Energy has estimated that over 50 GW of offshore wind power will be required for the United States to generate 20% of its electricity from wind. Developers are actively planning offshore wind farms along the U.S. Atlantic and Gulf coasts and several leases have been signed for offshore sites. These planned projects are in areas that are sometimes struck by hurricanes. We present a method to estimate the catastrophe risk to offshore wind power using simulated hurricanes. Using this method, we estimate the fraction of offshore wind power simultaneously offline and the cumulative damage in a region. In Texas, the most vulnerable region we studied, 10% of offshore wind power could be offline simultaneously because of hurricane damage with a 100‐year return period and 6% could be destroyed in any 10‐year period. We also estimate the risks to single wind farms in four representative locations; we find the risks are significant but lower than those estimated in previously published results. Much of the hurricane risk to offshore wind turbines can be mitigated by designing turbines for higher maximum wind speeds, ensuring that turbine nacelles can turn quickly to track the wind direction even when grid power is lost, and building in areas with lower risk.     

Adaptive agent-based manufacturing control and its application to flow shop routing control

The manufacturing industry is currently facing unprecedented challenges from changes and disturbances. The sources of these changes and disturbances are of different scope and magnitude. They can be of a commercial nature, or linked to fast product development and design, or purely operational (e.g. rush order, machine breakdown, material shortage etc.). In order to meet these requirements it is increasingly important that a production operation be flexible and is able to adapt to new and more suitable ways of operating. This paper focuses on a new strategy for enabling manufacturing control systems to adapt to changing conditions both in terms of product variation and production system upgrades. The approach proposed is based on two key concepts: (1) An autonomous and distributed approach to manufacturing control based on multi-agent methods in which so called operational agents represent the key physical and logical elements in the production environment to be controlled – for example, products and machines and the control strategies that drive them and (2) An adaptation mechanism based around the evolutionary concept of replicator dynamics which updates the behaviour of newly formed operational agents based on historical performance records in order to be better suited to the production environment. An application of this approach for route selection of similar products in manufacturing flow shops is developed and is illustrated in this paper using an example based on the control of an automobile paint shop.     

Shy but Getting By? An Examination of the Complex Links Among Shyness,Coping, and Socioemotional Functioning in Childhood

The purpose of the current study was to test a conceptual model of the mediated and moderated associations among shyness, coping strategies, and socioemotional functioning in middle childhood. Participants were 358 children (177 boys) aged 9–13 years (M = 10.16 years, SD =.95). Children completed self‐report assessments of shyness, coping style in response to a social stressor, internalizing problems, and peer difficulties. Among the results, shyness was positively associated with internalizing symptoms and negatively related to perceptions of peer difficulties. However, both of these associations were partially mediated by internalizing coping styles. Moreover, problem‐solving coping moderated these mediated pathways: among children who reported higher levels of problem‐solving coping, the associations between internalizing coping and outcomes were attenuated. Several gender differences also emerged, suggesting that problem‐solving coping may be particularly useful for shy boys. Results are discussed in terms of the complex but potentially critical role of coping in shy children's socioemotional functioning.
