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.     

The amount of ergonomics and user involvement in 151 design processes

Ergonomics, usability and user-centered design are terms that are well known among designers. Yet, products often seem to fail to meet the users' needs, resulting in a gap between expected and experienced usability. To understand the possible causes of this gap the actions taken by the designer during the design process are studied in this paper. This can show whether and how certain actions influence the user-friendliness of the design products. The aim of this research was to understand whether ergonomic principles and methods are included in the design process, whether users are involved in this process and whether the experience of the designer (in ergonomics/user involvement) has an effect on the end product usability. In this study the design processes of 151 tangible products of students in design were analyzed. It showed that in 75% of the cases some ergonomic principles were applied. User involvement was performed in only 1/3 of the design cases. Hardly any correlation was found between the designers' experience in ergonomic principles and the way they applied it and no correlations were found between the designers' experience in user involvement and the users' involvement in the design process.     

Disability beliefs and help-seeking behavior of depressed Chinese-American patients in a primary care setting

In this study the authors assessed the effects of disability beliefs, conceptualization and labeling of emotional disabilities, and perceived barriers on help-seeking behaviors among depressed Chinese Americans in a primary care setting. Forty-two Chinese Americans participated in semistructured interviews using established psychological measures and open-ended questions adapted from the Explanatory Model Interview Catalogue. The authors found that care utilization appears to be complicated by somatization of emotional problems, variations in causal attribution to depression, barriers to receiving mental health care, and the burden of comorbid physical conditions. Their findings highlight the importance of addressing these issues and educating patients about body-mind dialectic common to depression.     

Data mining in children and family services: the Contra Costa County experience

Despite access to a comprehensive administrative database that would allow for timely data retrieval and utilization, regular use of data to inform service provision remained infrequent at one children and family services agency. To address this issue, a research and evaluation manager was hired to facilitate regular data use and evidence-informed service provision. This led to a shift in agency culture that moved from viewing data collection as a burden and threat, to now valuing data as a powerful tool for improving programs and outcomes for children and families. This case study presents the experiences of this agency, describing the process by which the research and evaluation manager was hired, how data are now used by the agency, significant changes resulting from the agency's new data use practices, and perspectives of the evaluator and staff on data use and changes in agency culture.     

Using evidence-based accreditation standards to promote continuous quality improvement: the experiences of the San Mateo County Human Services Agency

Following a difficult period of service provision, an agency determined that drastic changes were needed to improve agency-wide capacity and functioning. The agency engaged in an organizational level self-assessment aimed at identifying areas for improvement and beginning work towards determining professional standards for service. Results of this organizational self-assessment paved the way for pursuing accreditation of its services, and the agency became the first public agency in its state to be accredited by the Council on Accreditation in all eligible services. This case study describes this agency's efforts in engaging in an organizational self-assessment, the analysis and codification of their practices, and their eventual development of a systematized process for capturing, evaluating and improving practice.     

农业企业的盈余操控更为严重吗?——基于中国上市公司的实证研究

采用2007—2014年中国沪深两市A股上市公司数据,研究行业特征和盈利能力对上市公司盈余管理水平的影响,实证分析结果表明:农业上市公司较非农上市公司具有更高的应计盈余管理水平和真实盈余管理水平;上市公司的盈利能力与应计盈余管理水平正相关,而与真实盈余管理水平负相关;较高的盈利能力强化了行业特征对真实盈余管理水平的正向影响,而对应计盈余管理水平则不具有这种影响。该研究不仅证实了农业上市公司较非农上市公司实施了更为严重的盈余操控,还揭示出上市公司的盈利能力对应计盈余管理水平和真实盈余管理水平的影响存在异质性以及盈利能力对行业特征与两种盈余管理水平之间关系的调节作用也存在异质性。     

12世纪前中央亚细亚草原的鞑靼人及其国家

波斯史学家拉施特丁的《史集》为研究蒙古人统治之前中央亚细亚草原上鞑靼人的历史提供了重要信息。拉施特丁认为,蒙古人统治之前中央亚细亚草原地区的居民以突厥部落为主,其组织"结构"为6个鞑靼人国家。本文以鄂尔浑和叶尼塞河流域突厥如尼文碑铭记载为依据,参照汉文史籍、敦煌和波斯手稿等的记载,探讨了9—12世纪在甘肃和新疆的广阔地域内活动的鞑靼人及其政权、9世纪上额尔齐斯河流域基马克人及其部落联盟的形成与鞑靼人之间的关系。
