Objective: This study assessed the features of the 100 most‐cited papers on oral health‐related quality of life (OHRQoL). Methods: The 100 most‐cited OHRQoL papers were collected from Web of Science, adopting a combined keyword search strategy. Google Scholar and Scopus databases were searched to compare citations. The following data were extracted from papers: title of the paper, number of citations, authorship, country, year of publication, title of the journal, study design, sample size, topic and OHRQoL instruments used. Graphical bibliometric networks were created using VOSviewer software. Results: The number of citations of the top 100 most‐cited OHRQoL papers ranged from 73 to 949. Fifty‐six papers received at least 100 citations and two received more than 400 citations. Most papers were from Canada (23%) and had been published in Community Dentistry and Oral Epidemiology (37%). David Locker was the most‐cited author (25 papers; 3,521 citations). The cross‐sectional study design was the most common (68%). The impact of oral health conditions on OHRQoL (43%) was the most frequent topic, and the Oral Health Impact Profile (OHIP) was the most commonly used OHRQoL instrument (48%). Conclusions: This bibliometric analysis highlighted the characteristics of the 100 most‐cited OHRQoL papers, demonstrating that this field is far from saturated. This list of the most‐cited articles can provide a reference point to guide oral health research, education and services. [ABSTRACT FROM AUTHOR]

In 2014 leading publishers withdrew more than 120 nonsensical publications automatically generated with the SCIgen program. Casual observations suggested that similar problematic papers are still published and sold, without follow‐up retractions. No systematic screening has been performed and the prevalence of such nonsensical publications in the scientific literature is unknown. Our contribution is 2‐fold. First, we designed a detector that combs the scientific literature for grammar‐based computer‐generated papers. Applied to SCIgen, it has a 83.6% precision. Second, we performed a scientometric study of the 243 detected SCIgen‐papers from 19 publishers. We estimate the prevalence of SCIgen‐papers to be 75 per million papers in Information and Computing Sciences. Only 19% of the 243 problematic papers were dealt with: formal retraction (12) or silent removal (34). Publishers still serve and sometimes sell the remaining 197 papers without any caveat. We found evidence of citation manipulation via edited SCIgen bibliographies. This work reveals metric gaming up to the point of absurdity: fraudsters publish nonsensical algorithmically generated papers featuring genuine references. It stresses the need to screen papers for nonsense before peer‐review and chase citation manipulation in published papers. Overall, this is yet another illustration of the harmful effects of the pressure to publish or perish. [ABSTRACT FROM AUTHOR]

We are developing a deterministic fluidic assembly process which uses software to sense, sort and assemble micron‐scale devices into desired patterns. This process can be adapted to assemble large numbers of microLEDs (uLEDs) over large areas with high throughput and nearly perfect yield. We present data demonstrating the precision and reliability of the process to illustrate its potential as a scalable process for manufacturing uLED displays. [ABSTRACT FROM AUTHOR]

Functional information software systems used by most construction companies are specifically designed to support one functional department such as scheduling or procurement. This causes communication barriers because cross-functional users do not have direct access to the functional department's software, are not literate regarding the subject software, and must depend on personal contact to provide current or updated information. Results of this research indicate the use of a graphic user interface, with equipment location drawings as the paradigm for obtaining information, can improve cross-functional information accessibility of scheduling information and reduce time necessary for schedulers to interface with foremen for nonroutine updates. The system was tested as a case study on a shutdown project with the assistance of the project's senior scheduler. It is concluded that the resulting increase in information accessibility will save time for both maintenance foremen and schedulers that will lead to an increase in productivity.

The article introduces the content of a 2006 special issue of the journal "Software Process Improvement and Practice."

Software engineering focuses on producing quality software products through quality processes. The attention to processes dates back to the early 1970s, when software engineers realized that the desired qualities (such as reliability, efficiency, evolvability, ease of use, etc.) could only be injected in the products by following a disciplined flow of activities. Such a discipline would also make the production process more predictable and economical. Most of the software process work, however, remained in an informal stage until the late 1980s. From then on, the software process was recognized by researchers as a specific subject that deserved special attention and dedicated scientific investigation, the goal being to understand its foundations, develop useful models, identify methods, provide tool support, and help manage its progress. This paper will try to characterize the main approaches to software processes that were followed historically by software engineering, to identify the strengths and weaknesses, the motivations and the misconceptions that led to the continuous evolution of the field. This will lead us to an understanding of where we are now and will be the basis for a discussion of a research agenda for the future. Copyright © 1998 John Wiley & Sons, Ltd. [ABSTRACT FROM AUTHOR]

Keeping up with rapidly growing research fields, especially when there are multiple interdisciplinary sources, requires substantial effort for researchers, program managers, or venture capital investors. Current theories and tools are directed at finding a paper or website, not gaining an understanding of the key papers, authors, controversies, and hypotheses. This report presents an effort to integrate statistics, text analytics, and visualization in a multiple coordinated window environment that supports exploration. Our prototype system, Action Science Explorer ( ASE), provides an environment for demonstrating principles of coordination and conducting iterative usability tests of them with interested and knowledgeable users. We developed an understanding of the value of reference management, statistics, citation text extraction, natural language summarization for single and multiple documents, filters to interactively select key papers, and network visualization to see citation patterns and identify clusters. A three-phase usability study guided our revisions to ASE and led us to improve the testing methods. [ABSTRACT FROM AUTHOR]

Projective mapping has recently attracted a lot of attention and the main sensory data acquisition software packages have developed interfaces to collect projective mapping data. However, the comparison between paper- and computer-based projective mapping has never been reported. The objectives of this research were to (1) compare the consensus maps and panelists' performances for paper- and computer-based projective mapping and (2) analyze the panelists' strategies while performing either tasks. In the first part of the study, 32 panelists were asked to perform both paper- and computer-based projective mapping on eight beer samples. In a second part of the study, 10 panelists were asked to repeat the tasks while 'thinking aloud' their strategy. There was no significant difference in panelists' performance as assessed by the people performance index between the paper and computer tasks. The consensus maps obtained were similar with respect to sample groupings, RV coefficients and variation explained by the first two dimensions. Individual panelists adopted similar strategies on paper and computer, but strategies differed greatly between panelists. Practical Applications The results reported here will help panel leaders in making informed decisions with respect to support choice when designing projective mapping tests. Additionally, an insight into the diversity of panelists' mapping strategies is provided which may inform further research and discussion into the most appropriate instructions given to panelists and/or type of panel used.

Making annotations on books and learning materials is part of students' everyday life. Although there are many computer-based annotation systems, many people prefer to print digital documents and make annotations on physical paper. We introduce a classification scheme for computer-based annotation systems and provide an overview of different systems using this scheme. During our investigations, we identified several shortcomings in existing annotation systems: limitation to single document formats, no capturing of relations to reflect lateral reading, loss of context information an annotation was created in and limited sharing capabilities among collaborative users. To overcome these shortcomings, we introduce the concepts of Anchor Points, Artefacts and Spaces. Anchor Points define locations in arbitrary documents. Artefacts capture annotations on multiple Anchor Points in several documents, allowing students to map their current working context that typically contains several open documents and a relationship between them. Spaces are repositories for the learning materials and annotations that are automatically replicated among collaborative mobile users. [ABSTRACT FROM AUTHOR]

Several scholars contend that learning with computer games and simulations results in students thinking more like professionals. Bearing this goal in mind, we investigated how a group of pharmacy students learnt with an in-house developed computer simulation, SimPharm. Adopting situated cognition as our theoretical lens, we conducted a case study involving 20 undergraduate students to tease out how they made meaning of a clinical case differently in two different contexts: a typical paper-based workshop and one enabled by SimPharm. The data collected included audio recordings of classroom discourse, focus group interviews and class observations. The findings identified differences in four areas: framing of the problem; problem-solving steps and tools used; sources and meaning of feedback; and conceptualisation of the patient. These four areas can serve as axes along which future evaluations of educational simulations can be carried out based on their affordances. [ABSTRACT FROM AUTHOR]

Background Existing tools for rapid cognitive assessment in HIV-positive individuals with mild cognitive deficits lack sensitivity or do not meet psychometric requirements for tracking changes in cognitive ability over time. Methods Seventy-five nondemented HIV-positive patients were evaluated with the Montreal Cognitive Assessment (MoCA), a brief battery of standardized neuropsychological tests, and computerized tasks evaluating frontal-executive function and processing speed. Rasch analyses were applied to the MoCA data set and subsequently to the full set of data from all tests. Results The MoCA was found to adequately measure cognitive ability as a single, global construct in this HIV-positive cohort, although it showed poorer precision for measuring patients of higher ability. Combining the additional tests with the MoCA resulted in a battery with better psychometric properties that also better targeted the range of abilities in this cohort. Conclusion This application of modern test development techniques shows a path towards a quick, quantitative, global approach to cognitive assessment with promise both for initial detection and for longitudinal follow-up of cognitive impairment in patients with HIV infection.

Aside from new software the blood cell separator TRIMA (GambroBCT) also received a newly designed separation chamber offering a novel single stage separation technology, called Trima Accel. We evaluated this new system focusing on productivity and donor comfort by comparing it to the previous version (Trima version 4) in collecting single-donor platelet concentrates (SD-PCs) and plasma. Each of 20 donors underwent platelet apheresis using both devices. We compared the collection efficiency (CE), the collections rate (CR), the volume of the collected plasma and the residual leukocytes. Furthermore we compared donor comfort in terms of duration of the donation, flow of citrate back to the donor and platelet and whit blood cell (WBC) loss. While the number of collected platelets and the platelet concentration did not differ significantly between both techniques the time of the procedure was reduced by 15.6% with Trima Accel. This results in an increase of the CR and CE of 25% and 15% respectively when using Trima Accel. Log normal probability plotting of WBC counts showed that both techniques complied with the European and the US leukoreduction guidelines. The mean flow of ACDA to the donor perminute and per litre blood volume was also reduced by 20%. These data show that the Trima Accel represents a further improvement in apheresis platelet production with a better productivity and donor comfort, especially regarding the mean flow of ACDA to the donor.

Maturity models are widely used in process improvement. The users of a maturity model should be confident that the weak points of the assessed processes can be found, and that the most valuable changes are introduced. Therefore, the evaluation of maturity models is an important activity. In this paper, a mapping study of the literature on the evaluation of maturity models is presented. Two databases are searched resulting in a set of relevant papers. The identified papers can be classified according to six categories, namely the maturity model under evaluation, type of evaluation, relation of the evaluators/authors to the maturity model, level of objectivity, main purpose of the paper, and size of study. Further, a framework of different evaluations of maturity models is developed, and the relevant papers are mapped to the framework. Finally, the relevant research on the evaluation of the maturity models in the Capability Maturity Model family is discussed in more detail. The result of this mapping study is a clear overview of how the evaluation of maturity models has been done, and some discussions are provided for further research on the evaluation of commonly used or newly developed maturity models.

The modern world greatly depends on information systems and the software that governs them. The software architecture defines and designs the holistic structure that the software will have, its components, the interaction between them and all the development is done around it. The purpose of this systematic literature review (SLR) is to analyse the software architectures used in educational websites, methodologies, technological components and empirical results. The search of the SLR yielded 23 studies from the most significant academic sources in education and software engineering. The results of the SLR show that the analysed educational websites were proposing a software architecture, developing a system, proposing a model, assessing of a platform, proposing a Folksonomy‐Based Ontology Maintenance, reviewing smart home design, and proposing a Web‐based platform to aid parallel, distributed and high‐performance computing education. Of the 23 selected studies, 13 carried out an evaluation of their research with either students, teachers, professionals or a combination of these. In conclusion, the selected studies present narrated experiments of projects or individuals that seek to improve collaborative learning in the educational area. Finally, an important finding is that the proposed software architectures do not contemplate laws or quality standards for universal access. [ABSTRACT FROM AUTHOR]

The article deals with selected papers presented at the 2004 annual e-Science All Hands Meeting in Great Britain. It is said that most papers report on how middleware is used to support a particular application. "Developing LHCb Grid software: experiences and advances," by Stokes-Rees and colleagues described DIRAC, a lightweight agent/service-based approach intended for production processing of data. Another paper served as an example in which middleware solution is applied to Earth system modeling.

Analysis of highly cited papers provides unique insights into the status of research in a given field. We sought to identify the top 100 most highly cited papers in the field of anorexia nervosa (AN). A free, publically accessible software was used to conduct an online search of publications with accompanying citation data. Search terms were selected to focus on papers dealing predominantly with AN, and the results manually screened to exclude out-of-scope publications. Papers in bulimia nervosa, eating disorder not otherwise specified and binge-eating disorder, were not included. The top 100 most highly cited papers in the AN field were identified. Of these, 34 garnered greater than 400 citations, classifying them as 'citation classics'. These works were divided into five categories, those dealing with epidemiological trends, medical/psychiatric comorbidities, treatment, mechanisms of disease and measurement/classification. Publications examining the epidemiology and underlying mechanisms of AN account for the majority of the top 100 papers. Scales and measurement tools have had the greatest impact, garnering the greatest number of average citations per paper. Although reasonably diverse, the top 100 papers highlight areas still lagging behind, including the neuroscience of AN as well as research into novel treatment strategies.

The article discusses the response and file exchange capabilities of Web-enhanced instruction. Two specific features of Blackboard, Digital Dropbox and Assignments, are considered. Digital Dropbox allows students to upload their work and permits the instructor to review at a later time. Assignments provides a better way of sharing information. It appears to provide features which potentially overcome the limitations of the Digital Dropbox. Most students preferred to use the Assignments feature because it was easier to use and required fewer steps, suggesting that other students will generally prefer this feature.

International collaborative papers are increasingly common in journals of many disciplines. These types of papers are often cited more frequently. To identify the coauthorship trends within Library and Information Science (LIS), this study analyzed 7,489 papers published in six leading publications (ARIST, IP&M, JAMIA, JASIST, MISQ, and Scientometrics) over the last three decades. Logistic regression tested the relationships between citations received and seven factors: authorship type, author's subregion, country income level, publication year, number of authors, document type, and journal title. The main authorship type since 1995 was national collaboration. It was also the dominant type for all publications studied except ARIST, and for all regions except Africa. For citation counts, the logistic regression analysis found all seven factors were significant. Papers that included international collaboration, Northern European authors, and authors in high-income nations had higher odds of being cited more. Papers from East Asia, Southeast Asia, and Southern Europe had lower odds than North American papers. As discussed in the bibliometric literature, Merton's Matthew Effect sheds light on the differential citation counts based on the authors' subregion. This researcher proposes geographies of invisible colleagues and a geographic scope effect to further investigate the relationships between author geographic affiliation and citation impact.

The article discusses various reports published within the issue including one about a theory of composing software components and another one about a combinatorial testing strategy for concurrent programs.

This paper presents a comparison of the cooperative multithreading model with the general concurrent programming model. It focuses on the execution time performance of a range of standard concurrent programming applications. The overall results are mixed. In some cases, programs written in the cooperative multithreading model outperform those written in the general concurrent programming model. The contributions of this paper are twofold. First, it presents a thorough analysis of the performances of applications in the different models, i.e. to explain the criteria that determine when a program in one model will outperform an equivalent program in the other. Second, it examines the tradeoffs in writing programs in the different programming styles. In some cases, better performance comes at the cost of more complicated code.

Summary: Given the escalating magnitude and intricacy of software systems, software measurement data often contains irrelevant and redundant features, resulting in significant resource and storage requirements for software defect prediction (SDP). Feature selection (FS) has a vital impact on the initial data preparation phase of SDP. Nonetheless, existing FS methods suffer from issues such as insignificant dimensionality reduction, low accuracy in classifying chosen optimal feature sets, and neglect of complex interactions and dependencies between defect data and features as well as between features and classes. To tackle the aforementioned problems, this paper proposes a many‐objective SDPFS (MOSDPFS) model and the binary many‐objective PSO algorithm with adaptive enhanced selection strategy (BMaOPSO‐AR2) is proposed within this paper. MOSDPFS selects F1 score, the number of features within subsets, and correlation and redundancy measures based on mutual information (MI) as optimization objectives. BMaOPSO‐AR2 constructs a binary version of MaOPSO using transfer functions specifically for binary classification. Adaptive update formulas and the introduction of the R2 indicator are employed to augment the variety and convergence of algorithm. Additionally, performance of MOSDPFS and BMaOPSO‐AR2 are tested on the NASA‐MDP and PROMISE datasets. Numerical results prove that a proposed model and algorithm effectively reduces feature count while enhancing predictive accuracy and minimizing model complexity. [ABSTRACT FROM AUTHOR]

Organizations creating software commonly utilize software development lifecycles (SDLCs) to structure development activities. Secure development lifecycles (SDLs) integrate into SDLCs, adding security or compliance activities. They are widely used and have been published by industry leaders and in literature. These SDLs, however, were mostly designed before or while cloud services and other hosted solutions became popular. Such offerings widen the provider's responsibilities, as they not only deliver software but operate and decommission it as well. SDLs, however, do not always account for this change. Security maturity models (SMMs) help to assess SDLs and identify improvements by introducing a baseline to compare against. Multiple of these models were created after the advent of hosted solutions and are more recent than commonly referenced SDLs. Recent SMMs and SDLs may therefore support hosted solutions better than older proposals do. This paper compares a set of current and historic SDLs and SMMs in order to review their support for hosted solutions, including how support has changed over time. Security, privacy, and support for small or agile organizations are considered, as all are relevant to hosted solutions. The SDLs analyzed include Microsoft's SDL, McGraw's Touchpoints, the Cisco's SDL, and Stackpole and Oksendahl's SDL2. The SMMs reviewed are OWASP's Software Assurance Maturity Model 2 and DevSecOps Maturity Model. To assess the support for hosted solutions, the security and privacy activities foreseen in each SDLC phase are compared, before organizational compatibility, activity relevance, and efficiency are assessed. The paper further demonstrates how organizations may select and adjust a suitable proposal. The analyzed proposals are found to not sufficiently support hosted solutions: Important SDLC phases, such as solution retirement, are not always sufficiently supported. Agile practices, such as working in sprints, and small organizations are often not sufficiently considered as well. Efficiency is found to vary based on the application context. A clear improvement trend from before the proliferation of hosted solutions cannot be identified. Future work is therefore found to be required. [ABSTRACT FROM AUTHOR]

This paper describes and formally analyses two communication protocols that manage the secure emission of digital certificates. The formal analysis is carried out by means of a software tool for the automatic verification of cryptographic protocols with finite behaviour. The tool is able to discover, at a conceptual level, attacks against security procedures. The methodology is general enough to be applied to several kinds of cryptographic procedures and protocols. It is the opinion of the authors that this approach contributes towards a better understanding of the structure and aims of a protocol, for developers, analysers and final users.

Fault-detection effectiveness of coverage criteria has remained one of the controversial issues in recent years. In order to detect a fault, a test set must execute the faulty statement, cause infection of the data state and then propagate the faulty data state to bring about a failure. This paper sheds some light on the earlier contradictory results by investigating the infection aspect of coverage criteria. For a given test criterion, the number of test sets satisfying the criterion may be very large, with varying fault-detection effectiveness. In a recent work the measure of variation in effectiveness of a test criterion was defined as ‘tolerance’. This paper presents an experimental evaluation of tolerance for control-flow test criteria by exhaustive test set generation, wherever possible. The approach used here is complementary to earlier empirical studies that adopted analysis of some test sets using random selection techniques. Four industrially used control-flow testing criteria, Condition Coverage (CC), Decision Condition Coverage (DCC), Full Predicate Coverage (FPC) and Modified Condition Decision Coverage (MCDC) have been analysed against four types of faults. A new test criterion, Reinforced Condition Decision Coverage (RCDC), is also analysed and compared. Copyright © 2004 John Wiley & Sons, Ltd. [ABSTRACT FROM AUTHOR]

The article presents James Brown's discussion of Fiona Steele's paper. The paper demonstrates the flexibility of a multilevel framework and the power of the available software to handle data. It indicates how the paper's use of the aML software and the MLwiN as an alternative package highlights the fact that computing can be a barrier for the applied modeller. It suggests comparing the output from a ML with equivalent quasi-likelihood output using sub-sample and full data to show the impact of using different estimation approaches.

The effectiveness of a video tutorial versus a paper-based tutorial for software training has yet to be established. Mixed outcomes from the empirical studies to date suggest that for a video tutorial to outperform its paper-based counterpart, the former should be crafted so that it addresses the strengths of both designs. This was attempted in the present study. Two consecutive experiments were conducted to examine the effect of tutorial type (video vs. paper based) on task relevance, self-efficacy, mood, flow and task performance. Participants were students from junior high school. Both studies reported significant, positive contributions of the tutorials to task relevance, self-efficacy, mood and flow. Both studies also found significant and substantial effects on task performance. A learning gain of about 30% was achieved in both studies. A retention task, completed only in Study 2, further revealed that the learning effect was stable. More importantly, performance on this task also indicated a significant interaction with tutorial type, favouring the video. The success of the video tutorial is ascribed to its design, which attended to and even incorporated key qualities of paper-based tutorials, while also capitalizing on the strengths of video.

Background: Those supporting children and young people who use augmentative and alternative communication (AAC) contribute to ongoing complex decision‐making about communication aid selection and support. Little is known about how these decisions are made in practice and how attributes of the communication aid are described or considered. Aims: To understand how communication aid attributes were described by those involved in AAC recommendations and support for children and young people, and how these attributes were described as impacting on AAC use. Methods & Procedures: A secondary qualitative analysis was completed of interview and focus group data from 91 participants involved in the support of 22 children and young people. Attributes of communication aids described by participants were extracted as themes and this paper reports a descriptive summary of the identified software (non‐hardware) attributes. Main Contribution: Decisions were described in terms of comparisons between commercially available pre‐existing vocabulary packages. Attributes related to vocabulary, graphic representation, consistency and intuitiveness of design, and ease of editing were identified. Developmental staging of vocabularies, core and fringe vocabulary, and vocabulary personalization were attributes that were described as being explicitly considered in decisions. The potential impact of graphic symbol choice did not seem to be considered strongly. The physical and social environment was described as the predominant factor driving the choice of a number of attributes. Conclusions & Implications: Specific attributes that appear to be established in decision‐making in these data have limited empirical research literature. Terms used in the literature to describe communication aid attributes were not observed in these data. Practice‐based evidence does not appear to be supported by the available research literature and these findings highlight several areas where empirical research is needed in order to provide a robust basis for practice. What This Paper Adds: What is already known on the subject: Communication aid attributes are viewed as a key consideration by practitioners and family members in AAC decision‐making; however, there are few empirical studies investigating language and communication attributes of communication aids. It is important to understand how those involved in AAC recommendations and support view communication aid attributes and the impact different attributes have. What this paper adds to existing knowledge: This study provides a picture of how communication aids are described by practitioners and family members involved in AAC support of children and young people. A range of attributes is identified from the analysis of these qualitative data as well as information about how participants perceive these attributes as informing decisions. What are the potential or actual clinical implications of this work?: This study provides a basis on which practitioners and others involved in AAC support for children and young people can review and reflect on their own practice and so improve the outcomes of AAC decisions. The study provides a list of attributes that appear to be considered in practice and so also provides a resource for researchers looking to ensure there is a strong empirical basis for AAC decisions.

Crater mapping using neural networks and other automated methods has increased recently with automated Crater Detection Algorithms (CDAs) applied to planetary bodies throughout the solar system. A recent publication by Benedix et al. (2020, https://doi.org/10.1029/2019ea001005) showed high performance at small scales compared to similar automated CDAs but with a net positive diameter bias in many crater candidates. I compare the publicly available catalogs from Benedix et al. (2020, https://doi.org/10.1029/2019ea001005) and Lee and Hogan (2021, https://doi.org/10.1016/j.cageo.2020.104645) and show that the reported performance is sensitive to the metrics used to test the catalogs. I show how the more permissive comparison methods indicate a higher CDA performance by allowing worse candidate craters to match ground‐truth craters. I show that the Benedix et al. (2020, https://doi.org/10.1029/2019ea001005) catalog has a substantial performance loss with increasing latitude and identify an image projection issue that might cause this loss. Finally, I suggest future applications of neural networks in generating large scientific datasets be validated using secondary networks with independent data sources or training methods. Plain Language Summary: I have compared two computer programs that use neural networks to identify craters on solar system bodies. The crater catalogs created by these programs have been previously compared against an existing human‐made catalog to measure their performance, but each comparison used a different method making it challenging to understand the difference between the catalogs. In this paper, I use the comparison methods from these two independent papers, discuss where the catalogs agree and disagree, and suggest why they disagree. I emphasize the need for more accurate and consistent methods to validate automatic crater‐mapping programs, especially when it is impractical for humans to check the craters found by automated methods. Key Points: The apparent performance of automatic crater detection algorithms is sensitive to the choice of metric used to gauge the performanceFeature Detection Algorithms trained to find spatial features should be used with appropriately projected images where possibleAs neural networks extend crater detection beyond practical human limits, validating their results with a independent networks is critical [ABSTRACT FROM AUTHOR]

This paper presents a generic formal framework to specify and test autonomous e-commerce agents. First, the formalism to represent the behaviour of agents is introduced. The corresponding machinery to define how implementations can be tested follows. Two testing approaches are considered. The first of them, which can be called active, is based on stimulating the implementation under test (IUT) with a test. The peculiarity is that tests will be defined as a special case of autonomous e-commerce agent. The second approach, which can be called passive, consists of observing the behaviour of the tested agent in an environment containing other agents. As a case study the framework is applied to the e-commerce system Kasbah. Copyright © 2005 John Wiley & Sons, Ltd. [ABSTRACT FROM AUTHOR]

The state space explosion restricts the error detection of concurrent software. The abstraction can provide a solution to avoid state space explosion, but it is easy to ignore important details, resulting in inaccurate detection results. This paper proposes a methodology of fine‐coarse‐grained automatic modelling for Java source programs. By the principle that the execution details of property‐unchecked, non‐interactive, and unrelated statements do not affect the model checking results, we model coarse‐grained model fragments for such statements, while fine‐grained model fragments for property‐checked, interactive, and related statements. Our method reduces the model and state space and ensures the error detection of the source program based on model checking. Moreover, we prove the equivalence of the fine‐grained model, the coarse‐grained model, and the program. Finally, this paper gives an experiment to verify the effectiveness of the proposed method.

Software effort estimation accuracy is a key factor in effective planning, controlling, and delivering a successful software project within budget and schedule. The overestimation and underestimation both are the key challenges for future software development, henceforth there is a continuous need for accuracy in software effort estimation. The researchers and practitioners are striving to identify which machine learning estimation technique gives more accurate results based on evaluation measures, datasets and other relevant attributes. The authors of related research are generally not aware of previously published results of machine learning effort estimation techniques. The main aim of this study is to assist the researchers to know which machine learning technique yields the promising effort estimation accuracy prediction in software development. In this article, the performance of the machine learning ensemble and solo techniques are investigated on publicly and non‐publicly domain datasets based on the two most commonly used accuracy evaluation metrics. We used the systematic literature review methodology proposed by Kitchenham and Charters. This includes searching for the most relevant papers, applying quality assessment (QA) criteria, extracting data, and drawing results. We have evaluated a state‐of‐the‐art accuracy performance of 35 selected studies (17 ensemble, 18 solo) using mean magnitude of relative error and PRED (25) as a set of reliable accuracy metrics for performance evaluation of accuracy among two techniques to report the research questions stated in this study. We found that machine learning techniques are the most frequently implemented in the construction of ensemble effort estimation (EEE) techniques. The results of this study revealed that the EEE techniques usually yield a promising estimation accuracy than the solo techniques. [ABSTRACT FROM AUTHOR]

Background: Humans often use co‐speech gestures to promote effective communication. Attention has been paid to the cortical areas engaged in the processing of co‐speech gestures. Aims: To investigate the neural network underpinned in the processing of co‐speech gestures and to observe whether there is a relationship between areas involved in language and gesture processing. Methods & Procedures: We planned to include studies with neurotypical and/or stroke participants who underwent a bimodal task (i.e., processing of co‐speech gestures with relative speech) and a unimodal task (i.e., speech or gesture alone) during a functional magnetic resonance imaging (fMRI) session. After a database search, abstract and full‐text screening were conducted. Qualitative and quantitative data were extracted, and a meta‐analysis was performed with the software GingerALE 3.0.2, performing contrast analyses of uni‐ and bimodal tasks. Main Contribution: The database search produced 1024 records. After the screening process, 27 studies were included in the review. Data from 15 studies were quantitatively analysed through meta‐analysis. Meta‐analysis found three clusters with a significant activation of the left middle frontal gyrus and inferior frontal gyrus, and bilateral middle occipital gyrus and inferior temporal gyrus. Conclusions: There is a close link at the neural level for the semantic processing of auditory and visual information during communication. These findings encourage the integration of the use of co‐speech gestures during aphasia treatment as a strategy to foster the possibility to communicate effectively for people with aphasia. WHAT THIS PAPER ADDS: What is already known on this subject: Gestures are an integral part of human communication, and they may have a relationship at neural level with speech processing. What this paper adds to the existing knowledge: During processing of bi‐ and unimodal communication, areas related to semantic processing and multimodal processing are activated, suggesting that there is a close link between co‐speech gestures and spoken language at a neural level. What are the potential or actual clinical implications of this work?: Knowledge of the functions related to gesture and speech processing neural networks will allow for the adoption of model‐based neurorehabilitation programs to foster recovery from aphasia by strengthening the specific functions of these brain networks.

An important cause of stunting is limited consumption of complementary foods, in terms of both quantities and nutrients. Although existing studies show a positive association between fathers' engagement and children's diet, programmes designed to improve complementary feeding practices often only target mothers. In response to this, maternal behaviour change communication (BCC), paternal BCC and food voucher programmes were designed and implemented in Ethiopia using a clustered randomized controlled trial design. The paternal BCC programme included gender‐equal messages to increase fathers' participation in childcare, household labour and decision making. The research reported in this paper is an examination of the BCC programmes, characterizing the behavioural, normative and control beliefs of both mothers and fathers in BCC households compared to those in control households. In this study, a total of 40 participants were included, with 13 mother–father pairs in the BCC + food voucher group, and seven pairs in the control group. Each participant was interviewed separately. We found that BCC mothers showed more gender‐equal tendencies than the control mothers despite being more rural in location. By contrast, the beliefs of BCC and control fathers were similar overall, suggesting men are more resistant to gender‐equal BCC. More work is needed to develop and test effective methods for changing fathers' beliefs and practices. Key messages: Mothers in behaviour change communication (BCC) group mothers held more gender‐equal beliefs than control mothers, while BCC and control fathers shared similar views, suggesting a male resistance to gender equality.Mothers found fathers' involvement in childcare socially acceptable but often perceived them as inexperienced, which limited their participation.Control mothers' traditional view on household chores maintained the conventional labour division, influencing fathers' involvement.Fathers typically resisted maternal control of resources; however, they agreed that the more knowledgeable should lead decision‐making. BCC mothers showed greater confidence in making household decisions as effectively as fathers. [ABSTRACT FROM AUTHOR]

From employees' varied interpretations of software efficacy to consumers' diverse beliefs about data privacy, technology frames refer to cognitive interpretations, assumptions and expectations that people use to comprehend the essence of information technology within a particular context. These frames differ across groups with different values, interests, experiences and expertise, having critical implications for researchers, managers and organizations. Despite theoretical enthusiasm to understand technology frames, limited methodological insights exist on how to systematically explore and compare technology frames. This gap impedes researchers from exploring novel questions related to technology frames, their variations and how they can be managed effectively. This paper proposes a cognitive method for comparing and elaborating on technology frames. Building on causal mapping and empirical studies, the method formulates steps to plan, elicit, compare and elaborate on the relationships that underlie framing differences. The method offers detailed recommendations and templates for effectively organizing and communicating diverse manifestations of framing differences and their implications. The paper concludes by highlighting the method's practical implications and encouraging research to advance extant knowledge of technology frames in the rapidly changing digital world.

The paper reviews the evolution of Interactive Management, later referred to as Structured Democratic Dialogue, starting from the early 1970s up to this date. The authors propose a generational classification scheme consisting of five periods based primarily on whether some or all stages of the process were implemented synchronously or asynchronously and whether the participants' presence was physical, virtual or hybrid. Other aspects such as modifications in the steps of the process; the evolution of the software; domains of applications; file management; methods of collecting or recording contributions, votes, clarifications and preparation of reports; and key players are also considered and reported within the context of the primary scheme. The paper considers key advances achieved at each generational stage in terms of process or software, discusses associated challenges and concludes with a view towards the future of the emerging fifth generation.

The article analyzes the value of the computer-assisted qualitative data analysis software (CAQDAS) that was developed as an alternative to the traditional pen, paper, and scissors approach to handling complex data. CAQDAS not only does faster, more systematically, and more easily what can be done by hand, but also "does more with data" thanks to "a range of techniques and tools that were impossible, unknown or too time-consuming before computers entered the field." Indeed, from its earliest incarnations, CAQDAS took advantage of the computer's text retrieval and database capabilities. Researchers could search and separate data files into segments that they could tag or code for easy retrieval. Over the years, software became more sophisticated, adding functions that went beyond these simple code-and-retrieve procedures. Current software packages allow researchers to record memos of their developing ideas and to write up the research. The software also enables them to use various formats to visualize the analysis, including indexes, graphical displays and tables.

The software testing state of practice is not as good as it ought to be. To reduce the gap between the state of practice and the state of the art, improvement in software testing is necessary. Existing improvement models focus too little on, or lack important aspects of, software testing. Therefore a new model is required. This paper describes a test improvement model called TIM. The model functions as a guidebook for test improvement. It is mainly inspired by SEI’s Capability Maturity Model and Gelperin’s Testability Maturity Model. TIM introduces new perspectives to test improvement, with explicit focus on cost-effectiveness and risk management. The model addresses five ‘key areas’ of testing: organization, planning and tracking, test cases, testware and reviews. TIM also includes an assessment procedure. The model is continuously revised as knowledge is gained through research and experience of use. This paper presents results from three applications of TIM. © 1997 John Wiley & Sons, Ltd.

Mutation testing, originally proposed for unit testing, has been extended to integration testing with the proposition of the Interface Mutation criterion. This paper presents the results of an experiment using two mutation-based testing criteria for unit and integration testing phases: the Mutation Analysis and the Interface Mutation adequacy criteria, respectively. The aim is to investigate how they can be used in a complementary way during the testing activity, establishing an incremental testing strategy comprising the unit and integration testing phases and guidelines on how to obtain a high mutation score with respect to mutation testing with a low cost, in terms of the number of mutants generated.

The mutation method assesses test quality by examining the ability of a test set to distinguish syntactic deviations representing specific types of faults from the program under test. This paper describes an empirical study performed to evaluate the effectiveness of object-oriented (OO) test strategies using the mutation method. The test sets for the experimental system are generated according to three selected OO test strategies and their effectiveness is compared by determining how well the developed test sets kill injected mutants derived from an established mutation system Mothra and the authors' own OO-specific mutation technique which is termed Class Mutation.

This paper outlines a general strategy for automated black-box testing of software components that includes automatic generation of component test drivers, automatic generation of black-box test data, and automatic or semi-automatic generation of component wrappers that serve as test oracles. This research in progress unifies several threads of testing research, and preliminary work indicates that practical levels of testing automation are possible.

To formally verify a large software application, the standard method is to invest a considerable amount of time and expertise into the manual construction of an abstract model, which is then analysed for its properties by either a mechanized or a human prover. There are two problems with this approach. The first problem is that this verification method can be no more reliable than the humans that perform the manual steps. If the average rate of error for human work is a function of the problem size, this holds not only for the construction of the original application, but also for the construction of the model. The standard verification trajectory therefore tends to become less reliable for larger applications. The second problem is one of timing and relevance. Software applications built by teams of programmers can change rapidly, often daily. Manually constructing an accurate abstraction of any one version of the application, though, can take weeks, which may jeopardize the validity of the results. In this paper a different verification method that avoids these problems is discussed. This method, which may be the precursor of a new class of testing techniques, was originally developed to allow for a thorough testing of parts of the software of a new commercial telephone switch. Here it is argued, though, that the method also has broad applicability to distributed software systems design in general. [ABSTRACT FROM AUTHOR]

Background: Children with Down syndrome have speech and language difficulties that are disproportionate to their overall intellectual ability and relative strengths in the use of gesture. Shared book reading between parents and their children provides an effective context in which language development can be facilitated. However, children with Down syndrome often take a passive role in shared book reading and the use of key word signing (KWS) as a shared book reading technique has never been investigated. Aims: This study aimed to compare children with Down syndrome's participation and use of KWS across two methods of shared book reading – one in which a book had key‐word sign prompts embedded (signed condition) and the other in which a book was read as normal (unsigned condition). Measures of child and parent communicative behaviour were taken in each condition to establish if differences emerged. Methods & Procedures: A total of 36 children with Down syndrome (aged between 18 and 61 months) and their mothers took part in the study. Parent–child dyads were videoed at home reading two books, one in a signed and one in an unsigned condition. Child measures included total number of signs produced in each condition and levels of attention and initiation as measured by the Pivotal Behaviour Rating Scale. Parent measures included total number of utterances, mean length of utterance (MLU) in morphemes and vocabulary diversity (VOCD). Parental measures were transcribed using the Codes for Human Analysis Transcripts (CHAT) software and analysed by the Computerised Language Analysis software (CLAN). Contrasts in outcomes between the signed and unsigned conditions were estimated using Poisson and linear mixed‐effects models, determined by the type of data. Outcomes & Results: Results showed that children attempted to sign significantly more in the signed than unsigned condition, as well as showing significant increases in their levels of attention and initiation. There was also a significant increase in the total number of utterances used by parents in the signed versus unsigned condition and a decrease in MLU. VOCD was similar in both conditions. Conclusions & Implications: This study shows that the simple act of embedding key word signs into commercially available books, during shared book reading between parents and young children with Down syndrome, positively affects children's participation (initiation and attention) and use of KWS. The use of KWS as a core shared book reading technique may therefore be a fruitful avenue to facilitate growth in the language abilities of young children with Down syndrome. What this paper adds: What is already known on this subject: Most children with Down syndrome have significant speech and language difficulties, with relative strengths in the use of gesture. Shared book reading is an activity reported to positively affect language. However, children with Down syndrome are reported to take a passive role in shared book reading and are therefore more dependent on their parents to use techniques that facilitate their levels of participation, in order to maximise potential benefits. To the best of our knowledge, the communicative effects of embedding key word signing (KWS) in shared book reading have never been examined with children with Down syndrome. What this paper adds to existing knowledge: This is the first study to investigate the communicative impact of parents embedding KWS in a shared book reading activity with their young children with Down syndrome. Our findings show that this relatively simple manipulation resulted in Increase in children's sign attempts.Increase in children's overall participation in shared book reading (indicated by levels of attention and initiation).Increase in the number of utterances produced by parents (primarily as a result of repetitions).Decrease in parental mean length of utterance. These findings suggest that embedding KWS in shared book reading is likely to facilitate increased language abilities in this cohort. What are the potential or actual clinical implications of this work?: Shared book reading is part of the daily routine for many parents and their children with Down syndrome. Integrating KWS is a relatively simple adaptation to this activity which is likely to enhance children's language skills. Therapists can encourage parents to do this at home to support work carried out at school and in a clinical setting. [ABSTRACT FROM AUTHOR]
