The website as a domain-specific genre

The paper takes an initial look at how the medial conditions of the screen and the Internet define new constraints for language and style of company websites. The paper first discusses how the impact of bad grammar is enhanced by the salience and universal visibility on the screen. The main part of the paper argues that the language of company websites often represents fossilized rhetorical structures as a paper text hangover from the medial conditions of reading written texts and views this residue as an evolutionary stage of the evolution towards a medially appropriate style.

Injunctions against Innocent Third Parties: The Case of Website Blocking

The paper discusses the phenomenon of injunctions against third parties that are innocent from the tort law perspective. One such type of injunction, website blocking, is currently appearing in the spotlight around various European jurisdictions as a consequence of the implementation of Article 8(3) of the Information Society Directive and Article 11 of the Enforcement Directive. Website-blocking injunctions are used in this paper only as a plastic and perhaps also canonical example of the paradigmatic shift we are facing: the shift from tort-law-centric injunctions to in rem injunctions. The author of this paper maintains that the theoretical framework for the latter injunctions is not in the law of civil wrongs, but in an old Roman law concept of ‘in rem actions’ (actio in rem negatoria). Thus the term ‘in rem injunctions’ is coined to describe this paradigm of injunctions. Besides the theoretical foundations, this paper explains how a system of injunctions against innocent third parties fits into the private law regulation of negative externalities of online technology and explores the expected dangers of derailing injunctions from the tracks of tort law. The author’s PhD project – the important question of the justification of an extension of the intellectual property entitlements by the in rem paradigm, along with its limits or other solutions – is left out from the paper.

Proportionality of Website Blocking: Internet Connectivity Providers as Copyright Enforcers

Internet connectivity providers have been ordered to block access to websites facilitating copyright infringement in various EU countries.In this paper, the proportionality of these enforcement measures is analysed. After addressing preliminary questions, the recent ECJ ruling UPC Telekabel Wien (C-314/12) and then case law from all Member States are examined from the perspective of proportionality. Finally, five criteria are submitted for proportionality analysis, and a proportionality evaluation is provided. The major observation is that the underlying goal of copyright enforcement has implications on how the scale tilts. In particular, ineffective enforcement mechanisms can be more easily accepted if the goal of symbolic, educational or politically motivated enforcement is considered legitimate. On the other hand, if the goal is to decrease the impact of infringement, higher efficiency and economically quantifiable results may be required

Can prospective usability evaluation predict data errors?

Increasing amounts of clinical research data are collected by manual data entry into electronic source systems and directly from research subjects. For this manual entered source data, common methods of data cleaning such as post-entry identification and resolution of discrepancies and double data entry are not feasible. However data accuracy rates achieved without these mechanisms may be higher than desired for a particular research use. We evaluated a heuristic usability method for utility as a tool to independently and prospectively identify data collection form questions associated with data errors. The method evaluated had a promising sensitivity of 64% and a specificity of 67%. The method was used as described in the literature for usability with no further adaptations or specialization for predicting data errors. We conclude that usability evaluation methodology should be further investigated for use in data quality assurance.

Usability and Acceptability of ASSESS MS: Assessment of Motor Dysfunction in Multiple Sclerosis Using Depth-Sensing Computer Vision

Background: Sensor-based recordings of human movements are becoming increasingly important for the assessment of motor symptoms in neurological disorders beyond rehabilitative purposes. ASSESS MS is a movement recording and analysis system being developed to automate the classification of motor dysfunction in patients with multiple sclerosis (MS) using depth-sensing computer vision. It aims to provide a more consistent and finer-grained measurement of motor dysfunction than currently possible. Objective: To test the usability and acceptability of ASSESS MS with health professionals and patients with MS. Methods: A prospective, mixed-methods study was carried out at 3 centers. After a 1-hour training session, a convenience sample of 12 health professionals (6 neurologists and 6 nurses) used ASSESS MS to capture recordings of standardized movements performed by 51 volunteer patients. Metrics for effectiveness, efficiency, and acceptability were defined and used to analyze data captured by ASSESS MS, video recordings of each examination, feedback questionnaires, and follow-up interviews. Results: All health professionals were able to complete recordings using ASSESS MS, achieving high levels of standardization on 3 of 4 metrics (movement performance, lateral positioning, and clear camera view but not distance positioning). Results were unaffected by patients’ level of physical or cognitive disability. ASSESS MS was perceived as easy to use by both patients and health professionals with high scores on the Likert-scale questions and positive interview commentary. ASSESS MS was highly acceptable to patients on all dimensions considered, including attitudes to future use, interaction (with health professionals), and overall perceptions of ASSESS MS. Health professionals also accepted ASSESS MS, but with greater ambivalence arising from the need to alter patient interaction styles. There was little variation in results across participating centers, and no differences between neurologists and nurses. Conclusions: In typical clinical settings, ASSESS MS is usable and acceptable to both patients and health professionals, generating data of a quality suitable for clinical analysis. An iterative design process appears to have been successful in accounting for factors that permit ASSESS MS to be used by a range of health professionals in new settings with minimal training. The study shows the potential of shifting ubiquitous sensing technologies from research into the clinic through a design approach that gives appropriate attention to the clinic environment.

A panel of librarians will use this innovative, interaction-driven method to assess iCONN, to demonstrate the potential and power of user testing, and to engage the audience by illustrating the process with live data instead of canned examples.

A comparative review of water disinfection methods appropriate for developing countries and their efficacy, cost-efficiency, and usability

Developing countries are heavily burdened by limited access to safe drinking water and subsequent water-related diseases. Numerous water treatment interventions combat this public health crisis, encompassing both traditional and less-common methods. Of these, water disinfection serves as an important means to provide safe drinking water. Existing literature discusses a wide range of traditional treatment options and encourages the use of multi-barrier approaches including coagulation-flocculation, filtration, and disinfection. Most sources do not delve into approaches specifically appropriate for developing countries, nor do they exclusively examine water disinfection methods.^ The objective of this review is to focus on an extensive range of chemical, physio-chemical, and physical water disinfection techniques to provide a compilation, description and evaluation of options available. Such an objective provides further understanding and knowledge to better inform water treatment interventions and explores alternate means of water disinfection appropriate for developing countries. Appropriateness for developing countries corresponds to the effectiveness of an available, easy to use disinfection technique at providing safe drinking water at a low cost.^ Among chemical disinfectants, SWS sodium hypochlorite solution is preferred over sodium hypochlorite bleach due to consistent concentrations. Tablet forms are highly recommended chemical disinfectants because they are effective and very easy to use, but also because they are stable. Examples include sodium dichloroisocyanurate, calcium hypochlorite, and chlorine dioxide, which vary in cost depending on location and availability. Among physio-chemical disinfection options, electrolysis which produces mixed oxidants (MIOX) provides a highly effective disinfection option with a higher upfront cost but very low cost over the long term. Among physical disinfection options, solar disinfection (SODIS) applications are effective, but they treat only a fixed volume of water at a time. They come with higher initial costs but very low on-going costs. Additional effective disinfection techniques may be suitable depending on the location, availability and cost.^
