The Web

Resource Oriented Architectures use the fundamental characteristics of the web itself in order to provide and update content on the web. While much of the philosophy concerning REST has been around since the early 1990s, the tools for turning these philosophies into working systems are only now becoming feasible. The fundamental tenets of ROA — that the web itself is primarily a giant database, that resources are abstractions that can be manifest in different representations, that a query-oriented resource architecture is more robust than a verb-oriented services architecture, and that a common publishing and syndication protocol is necessary to make such an architectural system work — are being adopted increasingly by people who realize that services oriented architecture are not effective at getting data from users or providing it to them in an easy to use way, but that ROA can do precisely that. Such a shift in perception is necessary but will nonetheless take a while to happen. It's necessary because the amount of information on the web is piling up faster than it can be indexed, and because under the current architectures the cost of developing "editors" for that data is prohibitive compared to the value of that information. It's necessary because the data within organizations is getting more complex than can be readily handled with a name/value approach to application development, and is increasingly contained within non-traditional data sources — Excel spreadsheets or Microsoft Word documents, for instance, or external data streams. Adoption will take time, however, because such an approach reduces the competitive barrier impedence that corporations can utilize to sell services, because it will take time to educate people in the underlying technologies and because there is a long-standing belief that ROA and SOA systems are incompatible. The rapidity at which companies lined up behind AtomPub, on the other hand, points to the fact that many IT organizations recognize the value to themselves that an AtomPub-type architecture opens up, while the educational curve is frankly true of most technologies — it will happen, slower than its proponents may hope but faster than its critics anticipate.

The Way

We examine the notion of “person” in cultural heritage settings (libraries, museums, and archives) and how this notion has implications for their function and purpose. Variations in the way persons are described, represented, and discussed have taken on new significance in emerging online environments predicated on reusing and sharing data from disparate sources. We start with a representative sample of systems and tools used for organizing knowledge in tangible cultural heritage, including metadata standards, conceptual models, and web data models, and for each, analyze their formal definitions of personhood. We asked what characteristics of a person are important in each of these definitions, and what might be the reasons for any variations among them. An analysis of the definitions themselves revealed five dimensions of personhood: life, actuality, biology, agency, and individuality. Using this framework along with the general literature on personhood we then describe the possible reasons, both historical and practical, for the definitions, their dimensions, and the differences among them. Finally, we speculate on the implications of such differences for emerging information environments.

Abstract. Automation surprise (AS) has often been associated with aviation safety incidents. Although numerous laboratory studies have been conducted, few data are available from routine flight operations. A survey among a representative sample of 200 Dutch airline pilots was used to determine the prevalence of AS and the severity of its consequences, and to test some of the factors leading to AS. Results show that AS is a relatively widespread phenomenon that occurs three times per year per pilot on average but rarely has serious consequences. In less than 10% of the AS cases that were reviewed, an undesired aircraft state was induced. Reportable occurrences are estimated to occur only once every 1–3 years per pilot. Factors leading to a higher prevalence of AS include less flying experience, increasing complexity of the flight control mode, and flight duty periods of over 8 hr. It is concluded that AS is a manifestation of system and interface complexity rather than cognitive errors.

Abstract. The association between health-related quality of life (HRQoL; Short-Form Health Survey-12; SF-12) and patient-reported morbidity-related symptoms measured by the Patient Health Questionnaire-15 (PHQ-15) is analyzed in a representative sample of older people in the general German population. Data from 1,659 people aged 60 to 85 years were obtained. Latent class analysis identified six classes of patients, which optimally categorize clusters of physical symptoms the participants reported: musculoskeletal impairments (39.8%), healthy (25.7%), musculoskeletal and respiratory/cardiac impairments (12.8%), musculoskeletal and respiratory impairments, along with bowel and digestion problems (12.9%), general impairments (4.9%), and general impairments with no bowel and digestion problems (4.8%). The participants’ SF-12 Physical Health Scores (η2 = .39) and their Mental Health Scores (η2 = .28) are highly associated with these latent classes. These associations remain virtually identical after controlling for age. The results provide evidence that profiles of patient-reported physical impairments correspond strongly with reduced HRQoL independently from aging processes.
