How to reduce workload--augmented reality to ease the work of air traffic controllers

In the future the air traffic will rise--the workload of the controllers will do the same. In the BMWi research project, one of the tasks is, how to ensure safe air traffic, and a reasonable workload for the air traffic controllers. In this project it was the goal to find ways how to reduce the workload (and stress) for the controllers to allow safe air traffic, esp. at huge hub-airports by implementing augmented reality visualization and interaction.     

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.     

Applications of a Capability approach to disability and the International Classification of Functioning, Disability and Health (ICF) in social work practice

As disability rates increase more social workers will require greater preparation to practice effectively with individuals with disabilities. The Capability approach and the International Classification of Functioning, Disability and Health provide helpful tools for social worker training. The capability approach emphasizes the need to assess what individuals are able to do in their real-life environments (capabilities) rather than capacity or functional status. The ICF provides helpful disability-related terminology and an actual classification to assist social workers to develop appropriate interventions that facilitate capability development among individuals with disabilities. Using the capability framework with the ICF will contribute to improved understanding of disability among social work students and practitioners.     

State of the (net)work address Developing criteria for applying social networking to the work environment

In an increasingly faster paced innovative world, maintaining the ability to innovate in spite of an aging work force will become every company's strongest leverage for success. Tapping the latent knowledge resources and creativity of overlooked employees and persisting crucial information for business conduct are promising results for social networking sites (SNS) in a working context. Usability and usefulness are exponential factors in creating a successful SNS. In order to make a SNS usable for a heterogeneous user group, analyses of user diversity in regard to social media need to be done. Furthermore differences in communication medium and frequency in regard to age, content, hierarchy position, departmental thresholds and company size need to be analyzed. For analysis purposes both qualitative and quantitative research methods were applied. Strong effects of age and communication content were found in survey with 194 participants.     

Performance Evaluation in Non-Governmental Organizations (NGOs): An Analysis of Evaluation Models and their Applications in Brazil

The objective of this article is to deepen the debate surrounding the practice of evaluation as performed by Brazilian NGOs. In order to accomplish this goal, we examined the results of an investigation conducted between 2007 and 2009 that had two stages: first, a national study and second, a quantitative and qualitative study made in the state of Santa Catarina. We also considered secondary sources of data from two important studies on the national level that were conducted in 2008 and 2009 by the Fonte Institute, with partnership of the Itaú Social Foundation. The results showed that most NGOs use internal rather than external evaluation and conduct evaluations focused on projects and programs. Furthermore, they used evaluation mainly to help decision making about projects. Consequently, the majority of NGOs focused their evaluations on results and were not concerned with creating spaces for self-reflection and learning.     

Shifting categories,changing attitudes: A boundary work approach in the study of attitudes toward migrants

Considerable research exists that examines attitudes toward migrants. Most studies are quantitative, relying on surveys or survey experiments, but a growing body of literature explores such attitudes from a qualitative perspective. At the same time, the study of symbolic boundaries and how people use cultural repertoires of meanings to draw distinctions between “us” and “them” is increasing. This review looks at research, both quantitative and qualitative, which has put these two streams of work into conversation with one another. We organize this work along three dimensions: (1) the micro-level of individuals and their life-worlds; (2) the meso-level of negotiation among the moral communities of civil society; and (3) the macro-level of institutions and policy. We also highlight those studies that cut across levels. By doing so, we help bridge the quantitative/qualitative divide. Studying attitudes toward migrants through the concept of symbolic boundaries allows us to apply a more sensitive and meaning-centered approach toward attitude formation, contestation and change and to explore the linkages to available cultural repertoires.     

Analysis of environmental flow requirements for macroinvertebrates in a creek affected by urban drainage (Prague metropolitan area,Czech Republic)

The habitat suitability index and environmental flow requirements were assessed for ten species of macroinvertebrates in a 2 km length section of the urban Boti? creek (average flow 0.4 m³ s^?1) in Prague. Boti? creek has been affected by two combined sewer overflows (CSO). Spring, summer and fall seasonal environmental flow requirements were identified using the Physical HABitat SIMulation System (PHABSIM) approach for the whole macroinvertebrate community: Spring – optimal flow 0.32–0.38 m³ s^?1, minimal flow 0.20–0.21 m³ s^?1 and maximal acceptable flow 0.91–0.93 m³ s^?1; Summer - optimal flow 0.42–0.45 m³ s^?1, minimal flow 0.19–0.21 m³ s^?1 and maximal acceptable flow 0.95–1.00 m³ s^?1; Fall - optimal flow 0.38–0.48 m³ s^?1, minimal flow 0.22–0.23 m³ s^?1 and maximal acceptable flow 0.95–0.98 m³ s^?1. The seasonal variability of environmental flow for all three categories is approximately 10%. Environmental flow requirements of the studied species and their life stages vary with depth, velocity and bottom substratum. Due to inflow from the CSOs, the optimal and maximal acceptable flow are not maintained and the maximal flow is exceeded by more than twice its value. Although the Instream Flow Incremental Methodology (IFIM) was primarily designed for large impounded rivers, the study proved its applicability in small streams affected by urbanization and urban drainage.     

A systemic approach to sociometric group research: Advancing the work of Leslie Day Zeleny, 1939-1947

This paper contributes to the exploration and analysis of compatibility and diversity across multiple, interrelated, structural configurations of groups geared toward the attainment of some objective requiring cooperative activity. The systemic nature of such contexts is addressed through a requisite approach that conforms to sociometric principles and methodological and measurement standards. Indexical properties, formulations, and computations are discussed in detail, and the provision of sample interpretations, along with an extensive array of visuals, fosters informed implementation. A classic data set is tackled with precision regarding its conception, construction and assimilation. The questions that this data set raises proffer innovative computational advancements, serving to promote it as one of the archetypes to be used in the teaching and research of social network analysis.     

Species richness and seasonality of spiders (Arachnida, Araneae) in an urban Atlantic Forest fragment in Northeastern Brazil

Species richness and forest seasonality of spiders in an urban fragment of Northeastern Brazil were investigated. Mata do Buraquinho is a remnant of Atlantic Rain Forest where no spider inventories have ever been made. Samplings during dry and wet seasons were carried out in order to establish if seasonality influences species richness and complementarily of the spider fauna. Pitfall traps, nocturnal collections, and beating tray samples were used to access a multi-guild spider fauna. Spider species were estimated using first order Jackknife method. Four hundred samples were obtained, resulting in 1681 adult spiders. A total of 166 species were recorded and 211 were estimated. No significant differences for species richness were observed between both periods, and the captured species were the same according to the complementarily coefficients. The fragmentation hypothesis as factor of biota impoverishment was not tested, but future investigations on this topic are suggested in the complex of forest remnants in João Pessoa.     

Promoting work ability and well-being in hospital nursing: the interplay of age, job control, and successful ageing strategies

Previous research shows that work ability of nurses decreases with age. In our study we therefore addressed the following questions: Do successful ageing strategies at work in terms of selection, optimization, and compensation (SOC) support the work ability of nurses? Does SOC mediate the relationship between job control (i.e., decision opportunities at work) and work ability? Does the mediation differ between age-groups? 438 nurses (Age Range 21-63 years) completed a questionnaire in the course of an employee survey. Results show that SOC is positively related with work ability. The positive effect of job control on work ability is significantly mediated by SOC. There are stronger mediating effects for elder nurses than for younger nurses. Results indicate that the interplay of job control and SOC at work helps to maintain the work ability of nurses in nursing care.     

Ichthyofauna diet changes in response to urbanization: the case of upper Paranapanema River basin (Brazil)

Alterations in stream environments can alter fish food availability, but there is little research data related to the impacts of urbanization on fish diets in tropical streams. Thus, we sought to compare the diet of ten fish species in urbanized and non-urbanized streams reaches. Fish stomach contents were obtained for four urban and five non-urban stream reaches from two medium-sized cities. We verified the similarity of diet composition from urbanized/non-urbanized streams. In-stream features mainly related to the substrate highlighted a perturbation gradient: gravel, pebbles and cobbles were associated to the wider urban reaches while silt were representative in the narrow pools from non-urban streams. Fishes changed their diet in response to urban and non-urban treatments. Omnivorous fishes consumed more detritus and Chironomidae and less terrestrial adult insects in urban reaches, while invertivorous fish consumed more terrestrial adult insects and Trichoptera larvae in the non-urbanized stream reaches. Although the management of the physical structure of streams in Brazil has been basically focused on riparian reforestation, our results suggest that a restoration plan for urban streams cannot be limited to reforestation of its surroundings, but also need to consider the physical structure of the channel, especially the substrate, which contributes to promote in-stream variability.

The coexistence of Fox (Sciurus niger) and gray (S. caroliniensis) squirrels in the Chicago metropolitan area

Two species of tree squirrel inhabit the Chicago region, the fox (Sciurus niger) and gray (S. caroliniensis) squirrel. Chicago residents submitted squirrel observations and associated landscape variables via a Website, allowing us to map squirrel distributions. Data were analyzed for patterns of correlation. At a smaller scale, we did a foot survey of fox and gray squirrels in the suburb of Oak Park, replicating an earlier study and comparing results. Gray squirrels were associated with densely populated areas, parks and campuses, fox squirrels with suburban areas. Compared to gray squirrels, fox squirrels were more likely to be observed in areas of high cat density. In the suburb of Oak Park, the current trend seems to be an extension of gray squirrel distribution and a decrease in fox squirrel distribution. Our study provides support for the idea that fox and gray squirrel coexistence is facilitated by a trade-off between managing the cost of predation and foraging efficiency, gray squirrels out-competing fox squirrels in areas of high food and low predator (or pet) density.
