Analysis of the work of air traffic controllers of the approach control area (APP) of Porto Alegre, Brazil

This article presents a study on the activities of the air traffic controllers of the Approach Control Area (APP) of Porto Alegre, Brazil, in different real scenarios. Based on interviews, questionnaires and the analysis of film of real scenes, the following were identified and analyzed: i) the perceptions of risk and complexity of the different air traffic scenes observed; ii) the cognitive factors (knowledge, strategy and attention dynamics) involved in the task and iii) the perception of the controller's workload. The results showed that the task complexity depends on the weather conditions, the number and type of aircraft in observation and that the controllers perceive the scenes in a similar way irrespective of their time in the profession and the type of control (radar or coordination). Attention is the cognitive factor with the greatest impact on the work and mental demand has the greatest impact on workload followed by time demand. The literature on the controllers work in Brazil is scarce and, therefore, this study aimed to contribute to the understanding of the work in one APP in order to promote future changes in the very problematic Brazilian air traffic system.     

Application of the user-centred design process according ISO 9241-210 in air traffic control

Designing a usable human machine interface for air traffic control is challenging and should follow approved methods. The ISO 9241-210 standard promises high usability of products by integrating future users and following an iterative process. This contribution describes the proceeding and first results of the analysis and application of ISO 9241-210 to develop a planning tool for air traffic controllers.     

Design considerations to improve cognitive ergonomic issues of unmanned vehicle interfaces utilizing video game controllers

Unmanned (UAVs, UCAVs, and UGVs) systems still have major human factors and ergonomic challenges related to the effective design of their control interface systems, crucial to their efficient operation, maintenance, and safety. Unmanned system interfaces with a human centered approach promote intuitive interfaces that are easier to learn, and reduce human errors and other cognitive ergonomic issues with interface design. Automation has shifted workload from physical to cognitive, thus control interfaces for unmanned systems need to reduce mental workload on the operators and facilitate the interaction between vehicle and operator. Two-handed video game controllers provide wide usability within the overall population, prior exposure for new operators, and a variety of interface complexity levels to match the complexity level of the task and reduce cognitive load. This paper categorizes and provides taxonomy for 121 haptic interfaces from the entertainment industry that can be utilized as control interfaces for unmanned systems. Five categories of controllers were based on the complexity of the buttons, control pads, joysticks, and switches on the controller. This allows the selection of the level of complexity needed for a specific task without creating an entirely new design or utilizing an overly complex design.     

Factor interaction influences on human performance in air traffic control: the need for a multifactorial model

In air traffic management (ATM) knowledge of the impact of human factors on performance is critical to address safety incidents. Previous research has largely focused on the effects of single factors on performance which has resulted in a comprehensive understanding of single factor effects. In current control environments however, the residual threats for incidents often result from the interaction of multiple human factors and the resulting cumulative impact on performance. This research uses a literature review, an analysis of over 400 European aviation incident reports and finally a survey of ATM professionals to assess the need for a multifactorial model of performance. Literature findings suggest that Human Factors approaches are fundamentally single-factor in nature, which is out of step with real ATM working contexts. An incident report analysis, supported by a survey of air traffic experts, suggests that multiple factor incident causation exists. This discrepancy suggests the need for a new approach to looking at how incidents occur, and their factors managed, on a day-to-day basis. The proposed solution is a multifactorial model of human performance.     

The road to abortion (II): how government got hooked

The first part of this series traced close links between eugenics (the effort to breed a "better" human race) and population control throughout the greater part of this century up to the 1960s. It stressed the population work of early eugenicists and eugenics sympathizers such as Frederick Osborn, Margaret Sanger, Gunnar Myrdal, Alan Guttmacher, Garrett Hardin and John D. Rockefeller 3rd. This second and concluding part will show how population controllers, from the 60s onward increasingly added economic and foreign-policy concerns to their original "eugenics" motive of improving human genetic stock. Working in both Democratic and Republican administrations, they gained major government backing for their programs and also played a key role in the legalization of abortion. I will use President Richard Nixon's administration as an example of heavy government involvement.     

Complexity analysis of the Next Gen Air Traffic Management System: trajectory based operations

According to Federal Aviation Administration traffic predictions currently our Air Traffic Management (ATM) system is operating at 150 percent capacity; forecasting that within the next two decades, the traffic with increase to a staggering 250 percent [17]. This will require a major redesign of our system. Today's ATM system is complex. It is designed to safely, economically, and efficiently provide air traffic services through the cost-effective provision of facilities and seamless services in collaboration with multiple agents however, contrary the vision, the system is loosely integrated and is suffering tremendously from antiquated equipment and saturated airways. The new Next Generation (Next Gen) ATM system is designed to transform the current system into an agile, robust and responsive set of operations that are designed to safely manage the growing needs of the projected increasingly complex, diverse set of air transportation system users and massive projected worldwide traffic rates. This new revolutionary technology-centric system is dynamically complex and is much more sophisticated than it's soon to be predecessor. ATM system failures could yield large scale catastrophic consequences as it is a safety critical system. This work will attempt to describe complexity and the complex nature of the NextGen ATM system and Trajectory Based Operational. Complex human factors interactions within Next Gen will be analyzed using a proposed dual experimental approach designed to identify hazards, gaps and elicit emergent hazards that would not be visible if conducted in isolation. Suggestions will be made along with a proposal for future human factors research in the TBO safety critical Next Gen environment.     

Recovery and detachment between shifts, and fatigue during a twelve-hour shift

The study investigated the role of recovery and detachment in the break period between two shifts for fatigue in the current shift. A time-based paper-and-pencil diary study was carried out observing sixty-four railway controllers over ten consecutive working shifts. The results demonstrated that fatigue in the current shift was not only affected by recovery and psychological detachment during break phases before a shift, but also by fatigue at shift onset and perceived workload during the shift.     

Daily Spillover of Low‐Income Mothers' Perceived Workload to Mood and Mother–Child Interactions

This study investigated associations of low‐income working mothers' daily perceived workload and their reports of their own mood and their interactions with their young children. Sixty‐one mothers were asked to report on their workload, mood, and interactions with their preschool‐age children every day for 2 weeks (N = 520 work days). Low‐income mothers reported significant day‐to‐day variability in workload. The results revealed a curvilinear pattern of negative work‐to‐family spillover: Both lower‐than‐average and higher‐than‐average workload days were associated with increased negative and tired mood, decreased positive mood, and increased harsh mother–child interactions. Although both younger and older mothers experienced a curvilinear pattern of spillover to daily mood, younger mothers in the period of emerging adulthood also experienced spillover to mother–child interactions, perhaps because they are still learning how to balance work and family demands. Both high and low workload are salient stressors in the daily lives of low‐wage working mothers.     

Contribution of mental workload to job stress in industrial workers

This study's central objective is to determine how several individual, organizational and ergonomic factors influence the relationship between job stress and mental workload for workers in an electronics company. A cross-sectional study was made as a test of hypotheses regarding that relationship. The sample is composed of 95 workers, of both sexes, from the electronics industry in the metropolitan zone of Guadalajara, Jalisco, Mexico. Ergonomic conditions were evaluated with the Ergonomic Evaluation List, stress was evaluated by administering the SWS-Survey to groups of subjects, and mental workload was evaluated with the NASA-TLX Workload Index. Using Cochran's and Mantel-Haenzsel statistics, the odds ratio for each of the independent variables was {e}stimated as a risk factor for job stress, and analysis was later conducted by means of logistic regression for those risks found to be significant. Of the 95 worker participants, 26.3% presented a high level of job stress and 17.9% of the workers were found to present high levels of mental workload. The results show that working hours, mental demand, temporal demand, and frustration when faced with a given task may be considered risk factors for job stress.     

Creating Community: Offering a Liberation Pedagogical Model to Facilitate Diversity Conversations in MFT Graduate Classrooms

Creating a safe place for open classroom engagement on topics of multiculturalism and diversity requires intentionality and honesty. Unless all, professor and students alike, feel safe talking about related issues, the attempt will result in a politically correct exercise in futility. This article focuses on how intentional pedagogical efforts can create a classroom environment conducive to therapeutic self-reflection and result in personal and professional transformation. Offerings include personal reflections, theoretical and pedagogical ideologies and practices, a classroom paradigm as exemplar, critical redefinitions, a survey of other pedagogical endeavors, a template for multicultural instruction, and recommendations.

Psychosocial factors related to job stress and women in management

This literature review explores women in management and how the psychosocial factors they face in the workplace affect their job-related stress level. The psychosocial factors identified include tokenism, sexual harassment and discrimination, work-family conflict, and workload. Various studies are cited and solutions to decrease job-related stress level are included.     

Developing a Contextual Consciousness: Learning to Address Gender,Societal Power,and Culture in Clinical Practice

Despite the growing number of culturally sensitive training models and considerable literature on the importance of training clinicians in larger contextual issues, research examining how students learn to apply these issues is limited. In this participatory action research project, we systematically studied our own process as marriage and family therapy (MFT) practicum students developing a contextual consciousness. Using grounded theory, we identified a three‐stage process: (a) raised awareness through clinical experimentation and developing a theoretical rationale, (b) reflective questioning involving challenging old perspectives and experiencing positive client–therapist interactions, and (c) an intentional new lens based on personal responsibility and commitment. Creating and maintaining a contextual lens required a safe, empowering group dynamic and accessing other forms of support and accountability after the practicum.     

Transforming the city: The potential for urban ethnographies of PR: The case of Latin America

Framed within García Canclini's concept of cultural hybridity, this paper will argue that “the city” and, consequently, the field of urban anthropology, offers great potential for the study of public relations and its audiences. Urbanisation will be one of the twenty-first century's biggest drivers of global economic growth (Dobbs et al., 2011) and public relations efforts will need to adapt to reflect the shifting urban environment. We will propose that cities provide opportunities for exploring the meanings, confines and possibilities of public relations as a socio-cultural practice. We will consider how ethnographically-inspired research can help us to further understand how public relations is understood and practised, both formally and informally, in large metropolitan cities and how public relations is influenced by, and can contribute to, urban cultural life. We will propose an ethnographic framework for research to explore the phenomenology of everyday lived experiences of public relations (PR) in relation to the complexity of the global processes which shape today's cities and the PR practices which take place within them. To contextualise our proposed research framework, we will draw on two particular cases from our own work: one of a project now completed in Mexico City, Mexico, and the other, a project in progress, in Lima, Peru.

A Collaborative Approach to Infant Research: Promoting Reproducibility,Best Practices,and Theory‐Building

The ideal of scientific progress is that we accumulate measurements and integrate these into theory, but recent discussion of replicability issues has cast doubt on whether psychological research conforms to this model. Developmental research—especially with infant participants—also has discipline‐specific replicability challenges, including small samples and limited measurement methods. Inspired by collaborative replication efforts in cognitive and social psychology, we describe a proposal for assessing and promoting replicability in infancy research: large‐scale, multi‐laboratory replication efforts aiming for a more precise understanding of key developmental phenomena. The ManyBabies project, our instantiation of this proposal, will not only help us estimate how robust and replicable these phenomena are, but also gain new theoretical insights into how they vary across ages, linguistic communities, and measurement methods. This project has the potential for a variety of positive outcomes, including less‐biased estimates of theoretically important effects, estimates of variability that can be used for later study planning, and a series of best‐practices blueprints for future infancy research.     

Soziales Lernen – Angewandte Sozialpsychologie für Lernende und Lehrende in Schule und Universität

In this paper, two interdigitated current training projects will be presented. The presentation is to show that social psychological theories can be applied profitably for school development. The content is about social learning in school. Social learning is aimed at the acquisition of social and emotional skills. These skills are positively correlated with the cognitive development of students. Social skills need to be explicitly taught and practiced, especially if they were developed insufficiently in childhood. In the project Social Learning we examine what contents may include social learning. In the project Classroom Management we explore how these contents are best taught and this teaching can be taught. Insights of Social Psychology are introduced for each resulting different extracts of reality and their uses are discussed.     

Immune responses to low back pain risk factors

$\underline{Objective}$: Investigate effects of interactions between biomechanical, psychosocial and individual risk factors on the body's immune inflammatory responses. $\underline{Background}$: Current theories for low back pain causation do not fully account for the body's response to tissue loading and tissue trauma. $\underline{Methods}$: Two groups possessing a preference for the sensor or intuitor personality trait performed repetitive lifting combined with high or low mental workload on separate occasions. Spinal loading was assessed using an EMG-assisted subject-specific biomechanical model and immune markers were collected before and after exposure. $\underline{Results}$: Mental workload was associated with a small decrease in AP shear. Both conditions were characterized by a regulated time-dependent immune response making use of markers of inflammation, tissue trauma and muscle damage. Intuitors' creatine kinase levels were increased following low mental workload compared to that observed in Sensors with the opposite trend occurring for high mental workload. $\underline{Conclusions}$: A temporally regulated immune response to lifting combined with mental workload exists. This response is influenced by personality and mental workload.
