Contradictions between scientific information and lay experiences may be a source of distress for MS patients, but we do not know how patients perceive and deal with these contradictions. OBJECTIVE: We aimed to understand whether scientific and experiential knowledge were experienced as contradictory in MS patient online forums and, if so, how these contradictions were resolved and how patients tried to reconcile the CCSVI debate with their own illness history and experience. METHODS: By using critical discourse analysis, we studied CCSVI-related posts in the patient online forum of the German MS Society in a chronological order from the first post mentioning CCSVI to the time point when saturation was reached. For that time period, a total of 117 CCSVI-related threads containing 1907 posts were identified. We analyzed the interaction and communication practices of and between individuals, looked for the relation between concrete subtopics to identify more abstract discourse strands, and tried to reveal discourse positions explaining how users took part in the CCSVI discussion. RESULTS: There was an emotionally charged debate about CCSVI which could be generalized to 2 discourse strands: (1) the \"downfall of the professional knowledge providers\" and (2) the \"rise of the nonprofessional treasure trove of experience.\" The discourse strands indicated that the discussion moved away from the question whether scientific or experiential knowledge had more evidentiary value. Rather, the question whom to trust (ie, scientists, fellow sufferers, or no one at all) was of fundamental significance. Four discourse positions could be identified by arranging them into the dimensions \"trust in evidence-based knowledge,\" \"trust in experience-based knowledge,\" and \"subjectivity\" (ie, the emotional character of contributions manifested by the use of popular rhetoric that seemed to mask a deep personal involvement). CONCLUSIONS: By critical discourse analysis of the CCSVI discussion in a patient online forum, we reconstruct a lay discourse about the evidentiary value of knowledge. We detected evidence criteria in this lay discourse that are different from those in the expert discourse. But we should be cautious to interpret this dissociation as a sign of an intellectual incapability to understand scientific evidence or a naïve trust in experiential knowledge. Instead, it might be an indication of cognitive dissonance reduction to protect oneself against contradictory information."],["dc.identifier.doi","10.2196/jmir.4103"],["dc.identifier.fs","618834"],["dc.identifier.pmid","26133525"],["dc.identifier.purl","https://resolver.sub.uni-goettingen.de/purl?gs-1/13579"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/58698"],["dc.language.iso","en"],["dc.notes.intern","Merged from goescholar"],["dc.relation.issn","1438-8871"],["dc.relation.orgunit","Institut für Allgemeinmedizin"],["dc.rights","CC BY 2.0"],["dc.rights.uri","https://creativecommons.org/licenses/by/2.0"],["dc.subject.mesh","Chronic Disease"],["dc.subject.mesh","Evidence-Based Medicine"],["dc.subject.mesh","Humans"],["dc.subject.mesh","Internet"],["dc.subject.mesh","Multiple Sclerosis"],["dc.subject.mesh","Patient Satisfaction"],["dc.subject.mesh","Social Media"],["dc.subject.mesh","Spinal Cord"],["dc.subject.mesh","Venous Insufficiency"],["dc.title","Scientific Versus Experiential Evidence: Discourse Analysis of the Chronic Cerebrospinal Venous Insufficiency Debate in a Multiple Sclerosis Forum."],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dc.type.subtype","original_ja"],["dc.type.version","published_version"],["dspace.entity.type","Publication"]]

This shift is welcome as an act of patient autonomy, reflected in the term \"expert patient\". At the same time, there is considerable concern that patients can be easily misguided by pseudoscientific research and debate. Little is known about the sources of information used in health-related online forums, how users apply this information, and how they behave in such forums. Objective: The intent of the study was to identify (1) the sources of information used in online health-related forums, and (2) the roles and behavior of active forum visitors in introducing and disseminating this information. Methods: This observational study used the largest German multiple sclerosis (MS) online forum as a database, analyzing the user debate about the recently proposed and controversial Chronic Cerebrospinal Venous Insufficiency (CCSVI) hypothesis. After extracting all posts and then filtering relevant CCSVI posts between 01 January 2008 and 17 August 2012, we first identified hyperlinks to scientific publications and other information sources used or referenced in the posts. Employing k-means clustering, we then analyzed the users' preference for sources of information and their general posting habits. Results: Of 139,912 posts from 11,997 threads, 8628 posts discussed or at least mentioned CCSVI. We detected hyperlinks pointing to CCSVI-related scientific publications in 31 posts. In contrast, 2829 different URLs were posted to the forum, most frequently referring to social media, such as YouTube or Facebook. We identified a total of 6 different roles of hyperlink posters including Social Media Fans, Organization Followers, and Balanced Source Users. Apart from the large and nonspecific residual category of the \"average user\", several specific behavior patterns were identified, such as the small but relevant groups of CCSVI-Focused Responders or CCSVI Activators. Conclusions: The bulk of the observed contributions were not based on scientific results, but on various social media sources. These sources seem to contain mostly opinions and personal experience. A small group of people with distinct behavioral patterns played a core role in fuelling the discussion about CCSVI."],["dc.identifier.doi","10.2196/jmir.2875"],["dc.identifier.isi","000331450500019"],["dc.identifier.pmid","24425598"],["dc.identifier.purl","https://resolver.sub.uni-goettingen.de/purl?gs-1/14475"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/34899"],["dc.notes.intern","Merged from goescholar"],["dc.notes.status","zu prüfen"],["dc.notes.submitter","Najko"],["dc.relation.issn","1438-8871"],["dc.relation.orgunit","Institut für Allgemeinmedizin"],["dc.rights","CC BY 2.0"],["dc.rights.uri","https://creativecommons.org/licenses/by/2.0"],["dc.title","Sources of Information and Behavioral Patterns in Online Health Forums: Observational Study"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dc.type.peerReviewed","yes"],["dc.type.subtype","original_ja"],["dc.type.version","published_version"],["dspace.entity.type","Publication"]]

However, when we only consider changes to the production code files this ratio increases to 66% to 87%. We find that about 11% of lines are hard to label leading to active disagreements between participants. Due to confirmed tangling and the uncertainty in our data, we estimate that 3% to 47% of data is noisy without manual untangling, depending on the use case.\n \n \n Conclusion\n Tangled commits have a high prevalence in bug fixes and can lead to a large amount of noise in the data.

This trend spawned hundreds of publications, whose results are helping to understand and improve the software development process. Due to the data-driven nature of this venue of investigation, we identified several problems within the current state-of-the-art that pose a threat to the replicability and validity of approaches. The heavy re-use of data sets in many studies may invalidate the results in case problems with the data itself are identified. Moreover, for many studies data and/or the implementations are not available, which hinders a replication of the results and, thereby, decreases the comparability between studies. Furthermore, many studies use small data sets, which comprise of less than 10 projects. This poses a threat especially to the external validity of these studies. Even if all information about the studies is available, the diversity of the used tooling can make their replication even then very hard. Within this paper, we discuss a potential solution to these problems through a cloud-based platform that integrates data collection and analytics. We created SmartSHARK, which implements our approach. Using SmartSHARK, we collected data from several projects and created different analytic examples. Within this article, we present SmartSHARK and discuss our experiences regarding the use of it and the mentioned problems.

We mined the changes in the textual content of the standards, the data in change requests from the past 5 years, and the mailing list archives from the past 10 years. In addition, to characterize the use of the TTCN-3 we investigated the meta-data of the contributions at the TTCN-3 User Conference, and the use of language constructs in a large-scale TTCN-3 test suite. Based on these data sets, we first analyze the amount, density, and location of changes within the different parts of the standard. Then, we analyze the activity and focus of the user community and the maintenance team in both the change request management system and the official TTCN-3 mailing list. Finally, we analyze the distribution of contributions at the TTCN-3 User Conference across different topics over the past 8 years and construct use anomalies during the development of a large-scale test suite.

TDL is designed as a domain-specific language for testing, consisting of a standardised abstract syntax (meta-model) and concrete syntaxes for textual specification, graphical design, and model exchange between tools. Its main purpose is to support a test methodology that is followed in the standardisation work for software-intense systems at ETSI and is also applicable in industrial projects. TDL offers a standardised language that enables the formal specification of both test objectives derived from system requirements and test descriptions that refine the test objectives and serve as blueprints for the implementation of executable tests. A standardised mapping of TDL specifications to test scripts in the standardised test execution language Testing and Test Control Notation version 3 (TTCN-3) widens the reach of TDL to ensure compatibility and consistency in generated executable tests. An open-source toolset for TDL has been developed as a common platform to accelerate the adoption of TDL and lower the barrier to entry for both, users and tool-vendors.
