The present paper provides a brief history of Electronic Data Processing Systems and their supporting user documentation. The problems inherent to paper documentation are highlighted. Techniques employed to improve on-line reject messages in addition to the development of an online user documentation system are discussed. Future challenges facing the human factors specialist involved in development of on-line documentation are outlined.

The directions of further developments in the modeling of sintering are pointed out, including multi-scale modeling of sintering, on-line sintering damage criteria, particle agglomeration, sintering with phase transformations. A true multi-scale approach is applied for the development of a new meso-macro methodology for modeling of sintering. The developed macroscopic level computational framework envelopes the mesoscopic simulators. No closed forms of constitutive relationships are assumed for the parameters of the material. When a time-step of the calculations is finished for one macroscopic element, the mesostructures of the next element are restored from the initial state according to the history of loading. The model framework is able to predict the final dimensions of the sintered specimen on a global scale and identify the granular structure in any localized area for prediction of the material properties.

This chapter documents the findings of research into the governance mechanisms within the distributed on-line community known as Wikipedia. It focuses in particular on the role of normative mechanisms in achieving social self-regulation. A brief history of the Wikipedia is provided. This concentrates on the debate about governance and also considers characteristics of the wiki technology which can be expected to influence governance processes. The empirical findings are then presented. These focus on how Wikipedians use linguistic cues to influence one another on a sample of discussion pages drawn from both controversial and featured articles. Through this analysis a tentative account is provided of the agent-level cognitive mechanisms which appear necessary to explain the apparent behavioural coordination. The findings were to be used as a foundation for the simulation of ‘normative’ behaviour. The account identifies some of the challenges that need to be addressed in such an attempt including a mismatch between the case findings and assumptions used in past attempts to simulate normative behaviour.

In spite of a long history of automated instruments being deployed in the water industry, only recently has the difficulty of extracting timely insights from high-grade, high-volume data sets become an important problem. Put simply, it is now relatively easy to be “data-rich”, much less easy to become “information-rich". Whether the availability of so many data arises from “technological push” or the “demand pull” of practical problem solving is not the subject of discussion. The paper focuses instead on two issues: first, an outline of a methodological framework, based largely on the algorithms of (on-line) recursive estimation and involving a sequence of transformations to which the data can be subjected; and second, presentation and discussion of the results of applying these transformations in a case study of a biological system of wastewater treatment. The principal conclusion is that the difficulty of transforming data into information may lie not so much in coping with the high sampling intensity enabled by automated monitoring networks, but in coming to terms with the complexity of the higher-order, multi-variable character of the data sets, i.e., in interpreting the interactions among many contemporaneously measured quantities.

Background: Low levels of public knowledge, incorrect beliefs, and anxiety are the most often mentioned factors that may negatively affect the implementation of preventive campaigns and timely diagnosis of cancer. Cancer is a major unresolved problem for global public health. As a result, many effective preventive measures need to be found and implemented. Methods: For a duration of 18 months, readers of the Polish scientific Internet portal were invited to participate in the Polish On-line Randomized Intervention aimed at Neoplasm Avoidance (PORINA) study. Level of cancer-related anxiety was our main measure (self-declared on a simple five-point Likert scale) in this analysis. Results: A total of 463 participants were qualified for the final analysis. Respondents with a positive family history of cancer (p < 0.001) declared the highest level of cancer-related anxiety, whereas lower levels were declared by those previously treated for cancer (p = 0.006). The conducted educational intervention reduced the declared level of cancer-related anxiety. Conclusions: The results of this study provide evidence that the use of web-based interventions aimed at increasing awareness could reduce cancer-related anxiety and may lead to more frequent consent to undergo some of the medical procedures used to diagnose or treat cancer.

Background. Cognitive models propose that auditory verbal hallucinations arise through defective self-monitoring and external attribution of inner speech. We used a paradigm that engages verbal self-monitoring to examine how deficits in this process are related to symptoms and diagnosis in patients with psychosis.Method. We tested 45 patients with schizophrenia. Fifteen had current auditory hallucinations, 15 had a history of (but no current) auditory hallucinations, and 15 had delusions but neither current nor previous hallucinations. We also tested 10 patients with affective psychosis and current auditory hallucinations, and 20 healthy volunteers. Participants read single adjectives aloud while the source and the pitch of the on-line auditory verbal feedback was manipulated, then immediately identified the source of the speech they heard (‘self’/‘other’/‘unsure’).Results. When reading aloud with distorted feedback of their own voice, patients with schizophrenia who had auditory hallucinations were more likely than controls to misidentify its source as ‘other’. Patients with delusions but no current hallucinations displayed a similar deficit, although there was a trend for this to be less marked. Patients with a history of hallucinations did not differ from controls. Patients with hallucinations in the context of an affective disorder made more unsure responses rather than misattributions.Conclusions. Difficulty with source monitoring was related to the acute psychotic state rather than a predisposition to hallucinations, and was evident in patients with affective psychosis as well as schizophrenia. External misattribution of source may reflect an impairment in verbal self-monitoring and/or the appraisal of ambiguous sensory material.
