The A-B Signal Detection Theory Model

The purpose of this research was threefold: (1) Present the a-b SDT model as an alternative framework to overcome the limitations of the underlying SDT model and the traditional measures of sensitivity and criterion setting, (2) Provide empirical support to validate the adequacy of the a-b SDT model, and (3) Conduct a Monte Carlo Study to compare and contrast the strengths and weaknesses of both the traditional and the a-b SDT models across the full spectrum of response values with the goal of providing researchers and practitioners with recommendations regarding the adequacy of each model. The results from this research have both theoretical implications and practical applications. The findings from the empirical study suggest that Green and Swets (1966)\u27s contention that the detection and response processes are independent from each other is questionable. Furthermore, the findings from the Monte Carlo Study suggest that the a-b SDT model provides more accurate measures to capture the dependency between these two processes. This is particularly important for researchers and practitioners who are interested in studying human-automation interaction factors and how sensory and perceptual factors may affect humans\u27 response biases while interacting with automated systems

The panel was composed of eight researchers and practitioners. The panelists are well-known experts in the area and offered differing views on a variety of different human-automation topics. The range of concepts and trends discussed in this panel include: general taxonomies regarding stages and levels of automation and function allocation, individualized adaptive automation, automation-induced complacency, economic rationality and the use of automation, the potential utility of false alarms, the influence of different types of false alarms on trust and reliance, and a system-wide theory of trust in multiple automated aids

Migration Industries and the State: Guestwork Programs in East Asia

Studies of migration industries have demonstrated the critical role that border-spanning businesses play in international mobility. To date, most research has focused on meso-level entrepreneurial initiatives that operate in a legal gray area under a state that provides an environment for their growth or decline. Extending this work, the present article advances a taxonomy of the ways states partner with migration industries based on the nature of their relationship (formal or informal) and the type of actor involved (for-profit or non-profit). The analysis focuses on low-paid temporary migrant work programs — schemes that require substantial state involvement to function — and examines cases from the East Asian democracies with strong economies that have become net importers of migrants: Taiwan, Japan, and South Korea. The conclusion, incorporating cases beyond Asia, explicates the properties and limits of each arrangement based on the degree of formality and importance of profit

4to. Congreso Internacional de Ciencia, Tecnología e Innovación para la Sociedad. Memoria académica

Este volumen acoge la memoria académica de la Cuarta edición del Congreso Internacional de Ciencia, Tecnología e Innovación para la Sociedad, CITIS 2017, desarrollado entre el 29 de noviembre y el 1 de diciembre de 2017 y organizado por la Universidad Politécnica Salesiana (UPS) en su sede de Guayaquil. El Congreso ofreció un espacio para la presentación, difusión e intercambio de importantes investigaciones nacionales e internacionales ante la comunidad universitaria que se dio cita en el encuentro. El uso de herramientas tecnológicas para la gestión de los trabajos de investigación como la plataforma Open Conference Systems y la web de presentación del Congreso http://citis.blog.ups.edu.ec/, hicieron de CITIS 2017 un verdadero referente entre los congresos que se desarrollaron en el país. La preocupación de nuestra Universidad, de presentar espacios que ayuden a generar nuevos y mejores cambios en la dimensión humana y social de nuestro entorno, hace que se persiga en cada edición del evento la presentación de trabajos con calidad creciente en cuanto a su producción científica. Quienes estuvimos al frente de la organización, dejamos plasmado en estas memorias académicas el intenso y prolífico trabajo de los días de realización del Congreso Internacional de Ciencia, Tecnología e Innovación para la Sociedad al alcance de todos y todas

Using Likelihood Alert Technology in Cockpit Displays of Traffic Information to Support Free Flight

The future of air traffic control imposes two major challenges. On the one hand, the increase in air traffic flow will dramatically augment the already existing high levels of workload for air traffic controllers. As a result, this increase in traffic density may jeopardize flight safety. On the other hand, standard aircraft separation tactics commanded by air traffic controllers are neither optimally efficient nor cost effective. Consequently, this makes it difficult for airlines to maintain an economic advantage. A potential solution to these problems is the introduction of free flight. The main goal of free flight is to reduce the level of workload of air traffic controllers and increase the efficiency and cost-effectiveness of aircraft separation by allowing pilots to make their own deviation decisions. However, the safe and efficient implementation of free flight will require state of the art cockpit displays of traffic information (CDTI) as well as advanced decision support tools (DSTs), which will need to be coupled with effective alerting algorithms. The purpose of this paper is to suggest the implementation of likelihood alert technology in CDTI, which may lead pilots to make more accurate decisions by allowing them to distinguish which conflicts are more likely to occur

Effects of Workload and Likelihood Information on Human Response to Alarm Signals

The purpose of this study was to examine how workload and likelihood information would affect participants’ responses to alarm signals while they performed a battery of tasks. As expected, participants’ overall response rates and false alarm response rates were significantly lower, and true alarm response rates were significantly higher when they used a likelihood alarm system. These results were particularly noticeable under high workload conditions. Results from this study suggest that although people may respond less often to alarm signals when they are provided with likelihood information, they will more likely respond to true signals rather than false alarms. Therefore, designers should incorporate likelihood information in alarm systems to maximize people’s ability to differentiate between true and false alarms and respond appropriately
