Texte intégralRésumé :
The process of analyzing the requirements for information security management systems is considered. The obligation to comply with the requirements of the international standard ISO/IEC 27001 is shown. This provides confidence to stakeholders in the proper management of information security risks with an acceptable level. This is due to the internal and external circumstances of influencing the goal and achieving the expected results of organizations. In addition, the identification of stakeholders, their needs and expectations from the development of information security management systems are also considered. It is established that now the main focus is on taking into account the requirements for the process of developing these systems or to ensure information security in organizations. The transformation of the needs, expectations and related constraints of stakeholders into an appropriate systemic solution has been overlooked. These limitations have been overcome through the method of analyzing the requirements for information security management systems. Its use allows, based on the needs, expectations and related constraints of stakeholders, to identify relevant statements in established syntactic forms. There is need to check each of them for correctness of formulation and compliance with the characteristics of both the individual requirement and the set of requirements. For their systematization, establishment of relations the graphic notation SysML is applied. In view of this, the requirement is considered as a stereotype of a class with properties and constraints. Relationships are used to establish relationships between requirements. Their combination is represented by a diagram in the graphical notation SysML and, as a result, allows you to specify the requirements for information security management systems. In the prospects of further research, it is planned to develop its logical structure on the basis of the proposed method.

Texte intégralRésumé :
Information technology (IT) development often suffers from requirements uncertainty as in many cases only preliminary information is available. Wrong decisions may lead to rework that wastes resources and delays the project. Coping with preliminary information is thus an important aspect of project management. The authors apply a case study approach to analyze how IT professionals react to preliminary information and why they do so. The authors base their study on a concurrent engineering research study that provides guidelines how the downstream process (implementation) should react if the upstream process (analysis) is not able to provide all information. According to the authors' results, IT professionals predominantly apply these proposed reactions. Nevertheless, it is often unclear why they react the chosen way. They recommend IT professionals to invest effort to more systematically consider multiple reactions. Future research should focus on how the upstream process should react when the downstream process needs to make a decision.

Texte intégralRésumé :
As technical communication gains the technology to deliver dynamic custom documents, the importance of audience analysis increases. As a major factor in supporting dynamic adjustment of document content, the audience analysis must clearly capture the range of user goals and information needs in a flexible manner. Replacing a linear audience analysis model with a multidimensional model provides one method of achieving that flexibility. With a minimum of three separate dimensions to capture topic knowledge, detail required, and user cognitive ability, this model provides the writer a means of connecting content with information requirements and ensuring the dynamic document fits varying audience needs.

Texte intégralRésumé :
Human needs to meet their needs cannot be separated from the role of information technology (IT) to provide data and information needs. In the education sector, the need for application of IT is carried out as an effort to support learning activities. One of application for education is a learning management system. Through this research, it will explain the system requirements for an authentic assessment information system based on web application. When conducting an authentic assessment, the teacher will assess the aspects of attitudes, knowledge and skills of student for vocational high school levels. The assessment tools for authentic assessments can be through by performance, writing, projects and portfolios assessments. The software development method used is the waterfall method, where for the needs analysis stage have used user requirement analysis and PIECES table. Meanwhile, for the design stage, we will use design tools by unified modeling language (UML). From the analysis and design of an authentic assessment information system based on web application, it is hoped that it can be one of the recommendations in building a learning management system media that is made in accordance with the assessment guidelines in the 2013 Curriculum.

Texte intégralRésumé :
Periodic drought, irrigation requirements, and the enforcement of mandatory watering restrictions have posed a challenge for homeowners and landscape managers to maintain acceptable turf quality during dry periods. Information regarding irrigation requirements and performance of common turfgrass species used for residential and commercial landscapes in the southeastern United States would be valuable. A Linear Gradient Irrigation System (LGIS) provides an efficient way to measure cultivar responses to variable moisture regimes. Nine commercially available cultivars from three turfgrass species: ‘Argentine’ bahiagrass (BH) (Paspalum notatum Flügge); ‘Common’ and ‘TifBlair’ centipedegrass (CP) [Eremochloa ophiruoides (Munro) Hack.]; ‘Captiva’, ‘Classic’, ‘Floratam’, ‘Palmetto’, ‘Raleigh’, and ‘Sapphire’ st. augustinegrass (STA) [Stenotaphrum secundatum (Walt.) Kuntze.] were evaluated during naturally occurring dry periods in 2010 and 2011 for visual quality, color, and density and chlorophyll index. An irrigation gradient ranging from 0% to 120% of reference evapotranspiration (ETo) was provided by LGIS. Centipedegrass and BH had less demands on supplemental irrigation to maintain acceptable quality during periodic drought compared with STA. ‘Argentine’ BH performed similar to ‘Common’ CP for its visual quality except at the irrigation level of 40% ETo. Among STA cultivars, ‘Palmetto’ performed poorest in its relative drought response than other cultivars. ‘Sapphire’ STA needs further study to better characterize its drought response. The irrigation level of 120% ETo decreased turf quality except for ‘Argentine’ BH, and the irrigation replacement at 40% to 80% ETo, depending on turfgrass species and cultivar, may provide enough supplemental moisture to maintain acceptable turf quality during short-duration drought (≈2 weeks) in north Florida regions.

Texte intégralRésumé :
An attempt is made in this paper to clarify some of the ambiguities surrounding the topic of information requirements. Whereas current systems analysis practice is mainly concerned with determining the current and future information needs of the 'users' of the proposed information system, this study points out that the requirements process should begin much earlier - information requirements should indeed be derived from the overall strategic business plan of the organization. If an information system is to be successful over the longer term, it is not so much the needs of the user that should be determined, but rather the needs of the organization. For this purpose, strategic information system planning is indispensable. In effect this means that the development life-cycle of an information system starts earlier than indicated in current models. The consequences of this broader view of requirements definition for, inter alia, systems analysis are reviewed.

Texte intégralRésumé :
This paper presents a functional analysis of the information needs of a chemical company for its response to hazardous material spills. An information system model, which formed the framework for this analysis, is presented. The analysis identified data requirements to support decision making and functional requirements to support communication of these decisions to the involved people and agencies. These requirements were compared to the existing system to identify current limitations. Potential solutions for overcoming these limitations are discussed.

Texte intégralRésumé :
SummaryBackground: Many informatics studies use content analysis to generate functional requirements for system development. Explication of this translational process from qualitative data to functional requirements can strengthen the understanding and scientific rigor when applying content analysis in informatics studies.Objectives: To describe a user-centered approach transforming emergent themes derived from focus group data into functional requirements for informatics solutions and to illustrate these methods to the development of an antibiotic clinical decision support system (CDS).Methods: The approach consisted of five steps: 1) identify unmet therapeutic planning information needs via Focus Group Study-I, 2) develop a coding framework of therapeutic planning themes to refine the domain scope to antibiotic therapeutic planning, 3) identify functional requirements of an antibiotic CDS system via Focus Group Study-II, 4) discover informatics solutions and functional requirements from coded data, and 5) determine the types of information needed to support the antibiotic CDS system and link with the identified informatics solutions and functional requirements.Results: The coding framework for Focus Group Study-I revealed unmet therapeutic planning needs. Twelve subthemes emerged and were clustered into four themes; analysis indicated a need for an antibiotic CDS intervention. Focus Group Study-II included five types of information needs. Comments from the Barrier/Challenge to information access and Function/Feature themes produced three informatics solutions and 13 functional requirements of an antibiotic CDS system. Comments from the Patient, Institution, and Domain themes generated required data elements for each informatics solution.Conclusions: This study presents one example explicating content analysis of focus group data and the analysis process to functional requirements from narrative data. Illustration of this 5-step method was used to develop an antibiotic CDS system, resolving unmet antibiotic prescribing needs. As a reusable approach, these techniques can be refined and applied to resolve unmet information needs with informatics interventions in additional domains.Citation: Bright TJ.

Texte intégralRésumé :
Covid-Pandemin i början av 2020 har på ett eller annat sätt påverkat och begränsat hur anställda arbetar. Flera förändringar har skett som att företag med förutsättningarna förlagt arbetet till de anställdas hem. Detta har bidragit till att spontana interaktioner minskat, nya arbetsmetoder har formats och nya verktyg lanserats. Denna nya situation har medfört en rad utmaningar och möjligheter kring hur anställda samarbetar och delar kunskap kring kundbehov. Syftet med uppsatsen har varit att undersöka hur mjukvaruföretag har anpassat metoder, aktiviteter och arbetsprocesser vid utvecklingsarbetet av mjukvara. Syftet besvaras genom att utreda processerna vid krav och behovsanalys samt till att kartlägga samarbetsverktyg, arbetssituationen hemifrån, interaktioner inom projektgruppen samt vilka möjligheter och hinder som finns vid kontakt med kunder. En kvalitativ intervjustudie genomfördes på två mjukvaruföretag med sex informanter inom olika roller i en projektgrupp med tre krav: att de arbetat på distans under pandemin, att de har kundkontakt samt är involverade i utveckling av mjukvara. Resultatet visar att distansen leder till möjligheter i kombinationen arbets- och privatliv exempelvis ingen restid, lättare att planera in aktiviteter som barnlämning och hämtning. Vidare pekar resultatet på utmaningar och svårigheter i digitala interaktioner mellan arbetskollegor och kunder som att det exempelvis är svårt att tolka kroppsspråk, ansiktsuttryck och tystnad samt att spontana interaktioner minskat. Utmaningarna leder till att det kan bli svårt att uppfatta tyst kunskap vilket kan påverka arbetet med kravanalys och i sin tur slutprodukten. Resultatet analyserades genom att betrakta hur kunskap kring kundbehov skapas exempelvis vilka metoder som används samt vilka förutsättningar som projektgruppen lever upp till för framgångsrik kunskapsdelning på distans. Analysen visar att den ökade användningen av digitala verktyg har skapat en social acceptans för digitala möten vilket resulterat i frekvent kontakt med kund samt skapande av mer underlag som exempelvis inspelade möten. När arbetet sker uteslutande via digitala verktyg kan fler roller involveras tidigare i utvecklingsprocessen. Då kommunikationen sker digitalt kan en minskning i förståelse för kundens behov upplevas då exempelvis informella möten inte längre sker samt att metoder som observationer inte längre används. Projektgrupper bör anpassa sig för att möta utmaningarna som distansen medför genom att exempelvis minst en gång om dagen träffa kollegorna i digitala träffar i syfte att ingen ska känna sig ensam och för att stärka samhörigheten. Digitala intervjuer och återkoppling med kund sker oftare och leder till ökad mängd lagrad data som exempelvis inspelningar och mötesanteckningar. Ökningen behöver hanteras i syfte att den blir lättillgänglig för projektmedlemmar. Vidare försöker projektgrupper anpassa sig till minskningen av fysiska interaktioner genom att aktiviteter som observationer och workshops inte längre används.<br>The Covid-Pandemic at the beginning of 2020 has in one way or another affected and limited how employees work. Changes such as companies with the possibility relocating the work to the employees' homes, changes in spontaneous interactions, new working methods have been formed and new tools have been launched. This new situation has led to several challenges and opportunities regarding how employees collaborate and share knowledge about customer needs. The purpose of the thesis has been to investigate how software companies have adapted methods, activities and work processes. The purpose is answered by investigating the processes for requirements and needs analysis and for mapping collaboration tools, the work situation from home, interactions within the project group and the opportunities and obstacles that exist in contact with customers. A qualitative interview study was conducted at two software companies with six informants in different roles with three requirements: that they worked remotely during the pandemic, that they have customer contact and are involved in software development. The results show that distance work leads to opportunities in the combination of work and private life, for example no travel time and easier planning of picking up children from school. Furthermore, the results point to challenges and difficulties in digital interactions between work colleagues and customers in that, for example, it is difficult to interpret body language, facial expressions and silence and that spontaneous interactions have decreased. The challenges lead to becoming difficult to perceive tacit knowledge, which can affect the work with requirements analysis and in turn the product. The results were analysed by considering how knowledge about customer needs is created, for example which methods are used and which conditions the project group lives up to for successful knowledge sharing at a distance. The analysis shows that the increased use of digital tools has created a social acceptance for digital meetings, which has resulted in frequent contact with customers and the creation of more data in the form of, for example, recorded meetings. When the work is done exclusively with digital tools, more roles can be involved earlier in the development process. When communication takes place digitally, a reduction in understanding of the customer's needs can be experienced when, for example, informal meetings no longer take place and methods such as observations are no longer used. Project groups should adapt to meet the challenges posed by the distance by, for example, meeting colleagues in digital meetings at least once a day for no one to feel alone and to strengthen cohesion. Digital interviews and customer feedback take place more often and lead to an increased amount of stored data in the form of, for example, recordings and meeting notes. The increase in data needs to be managed for it to be easily accessible to project members. Furthermore, project groups try to adapt to the reduction in understanding and perception of tacit knowledge by no longer using activities such as observations and workshops.

Texte intégralRésumé :
Information management and customised applications of information technology are essential in knowledge based organisations. The implementation of an information system is one aspect of information management that regularly requires a huge amount of time and money. Therefore, to avoid the waste of resources it is important to know the users' needs and demands. By using an information analysis it is, for example, possible to investigate information needs, technical supported information and communication processes or designs. The aim of the thesis is to survey methods of analysis that identify users' demands and needs in terms of information management and systems. Additionally, it aims at finding out, which models are appropriate for cooperative and decentralised organisations respectively. Firstly, issues regarding the present information society and methods of information analysis are identified by carrying out an initial literature research. Secondly, an information analysis is developed and performed in a financial institution, which is characterised by its cooperative and decentralised organisation. The analysis consists of a standardised questionnaire and guided interviews. Both aim at analysing users' behaviour, the usefulness of the information systems supplied and the demands for a new system. The main outcome of this thesis is that there are different fields of application and models of information analysis. Finally, a combination of two methods was particularly appropriate for the investigated financial institution. The findings of the empirical study suggest that a new system that reduces the information overload and improves the organisation of information is requested by larger branches. Smaller branches tend to be less affected by the information overload and as a result they feel more comfortable with the current information management. Based on these results, recommendations for a future information system are given to the financial institution and suggestions on how the chosen method could be improved are made.

Texte intégralRésumé :
The objective of the study is to expand knowledge regarding aspects related to behavior when using databases, for alumni that found themselves working towards a masters or doctoral thesis at the College of Mexico (seria mejor usa el nombre aqui). The study bases itself on the Information Seeking Process(ISP) model proposed by Kuhlthau. The model consists of 6 phases> initiation, selection, exploration, formulation, collection and presentation. The models 6 states incorporate three branches, or axis of the experiences: affection (feelings/emotions), cognitive (thoughts), and physical (actions). The model develops 3 instruments to investigate knowledge of databases and the skills and attitude that students apply when using them. Using the results obtained it is possible to observe subjective aspects that are involved in the selection and use of databases. It is evident that the (iteractiva como interactiva en ingles interactive o iterativa en ingles iterative) nature of information searching where users of information attending the need for information take steps, return over the same steps or skip steps, depending on a diverse group of factors like knowledge prior abilities that a user may have when using databases. Furthermore it has been verified that natural need for information determines significantly the selection of the source to investigate, and the use of those sources

User testing can help to evaluate and improve the usability of websites. Conventional methods as laboratory tests are rather complex and therefore costly and time consuming. Novel online tests applying to specific usability aspects are supposed to facilitate the evaluation of websites. This study is to find out if online experiments can be useful to evaluate information
structure and navigation design. Based on the website of the University of Hildesheim,
findings of the online usability tests are compared to findings of laboratory tests. The
comparison shows which kind of problems can be detected by online experiments. Also
advantages and disadvantages of both approaches are presented to help deciding for the adequate method in prospective evaluations.

Texte intégralRésumé :
Purpose: The following research study is aimed at understanding the information practices of music fans, particularly fans of tango music and metal music in the city of Medellín. Design/methodology/approach: Based on three conceptual starting points, a social practice theory, the serious leisure perspective, and the information transfer model, a qualitative study was designed, with an exploratory and descriptive scope. In-depth interviews and observations were carried out with 18 music fans, 9 of tango music, 9 of metal music. The collected data was analized deductively using categories found on the conceptual models, and comparing it with the findings of a review of 50 previous studies found on the literature. Findings: The studies found on the literature suggest that up to this moment, music information behaviour has not been studied in a comprehensive manner, rather each activity has been viewed as isolated from others. The statements gathered from fans allow us to assert that an information practice is a coherent whole, all its activities are connected to each other and integrated with each person‟s lifestyle. Personal factors sucha as general understandings, values and world view are the ones that have greater incidence upon the practice, more so tan sociodemographic factors. A model for information practice is presented that describes all these elements. Originality/value: This study proposes a new theoretical and practical approach to the subject. The findings are an original and novel description upon which it is posible to conduct further studies.

Texte intégralRésumé :
This work examines the labyrinth of complexities that confronts the Intelligence Community in its efforts to provide accurate and timely intelligence in support of American foreign policy and national security interests. Kennedy begins with an analysis of the collection processes and the obstacles that must be overcome if accurate and meaningful information is to be obtained. He addresses such issues as the need for strategic vision and clarity in setting priorities, as well as constraints imposed by the executive branch and the complexities associated with translating priorities into collection programs. The focus then shifts to the obstacles that confront those tasked to analyze collected information, examining such issues as the impact of people, technology, and budgets on the overall analytical effort. The third area of emphasis for Kennedy centers on the quality control of collection and analysis, addressing both Executive Branch and Congressional Oversight of the intelligence processes. Finally, he examines issues associated with the distribution and use of the intelligence products - the so-called end game obstacles. Issues addressed include the lack of presidential support for and confidence in the Intelligence Community, the impact of worst-case planning, and the coloring of intelligence to suit policy preferences. Ultimately, the component parts provide the reader with a broad understanding of the Intelligence Community and the difficulties it faces as it strives to keep the United States safe and informed. In the wake of recent intelligence failures, the Intelligence Community has come under increasing attack. Yet few people outside of government, and all too frequently many inside of government, do not understand just how difficult and complex are the processes of collecting, analyzing, disseminating, and effectively using gathered intelligence. The purpose of this undertaking is to illustrate the many road blocks the Intelligence Community confronts as it attempts to meet the needs of policymakers and to provide the average American, students of foreign and security policy, and many inside of government with a more comprehensive understanding of the overall intelligence effort. The complex processes for identifying, prioritizing, and communicating requirements to the intelligence community are further complicated by a lack of strategic vision on the part of American policy makers. Kennedy contends that those problems are compounded by Executive department oversight of the Intelligence Community, which has contributed significantly to past failures of intelligence. Moreover, the lack of effective oversight by Congress of the Intelligence Community in terms of the quality of its product upon which Congress has often been required to make life and death decisions too often has been either seriously deficient or non-existent. All too frequently, Kennedy notes, what could be called political coloring adversely affects the intelligence product. Intelligence findings are often colored to suit the preferred policies of decision-makers. As a result, actions are taken based on assumptions and opinions that are not supported by existing intelligence.

Texte intégralRésumé :
Abstract The educational setting is carefully examined to gather all the essential information required for designing an effective digital learning environment (see Fig. 4.1). Identifying training needs ensures alignment with learners’ characteristics and requirements, preventing designs that might overlook critical needs. Resource assessment is equally crucial; even if a learning solution is well suited to the context, factors such as scheduling (e.g., lesson frequency and duration) or infrastructure (e.g., room setup and ICT resources) could present challenges to implementation. Based on insights from the context analysis, the intended learning outcomes are then defined.

Texte intégralRésumé :
AbstractWith the implementation of China’s Belt and Road Initiative, a new wave of globalization is taking shape, promoting the growth of international service requirements, which requires pre-deployment of international infrastructure. The construction of international communications infrastructure is an important guarantee for China’s major international activities, external communication activities, and the normal operation of global and regional economies. International Communication Accesses is an important part of international infrastructure. The development and construction of international accesses is not an intrinsic mode, which involves many factors. It needs long-term planning and local adaptation; it relies on both the policy environment and basic network resources; it should consider both return on investment and convenience services. This document puts forward the future construction route of international communication accesses based on the analysis of factors including macro policies, geographical environments, service requirements, circuit quality improvement, transmission resources, fund support, and security assurance.

Texte intégralRésumé :
Abstract User involvement is critical in large-scale agile software development. User representatives bridge access gaps and align development teams with user expectations. However, research primarily focuses on development-side user representatives like product owners or user experience designers, overlooking user-side representatives who bring practical expertise and bridge communication between users and development teams. This highlights a gap in understanding user-side representatives’ roles in large-scale agile software development for fostering effective collaboration. In this paper, we ask the following research question: What are the roles, responsibilities, and challenges of user-side representatives in large-scale agile software development? We conducted an exploratory case study within a large public organization using interviews, focus groups, and document analysis to answer this. We investigated two established user-side representative roles: implementation coordinators and change agents. In our distributed case organization, implementation coordinators serve as county-level contact points, overseeing planning, coordination, training, and follow-up of software release implementation. Based in local offices, change agents facilitate requirements elicitation, test software quality, train users, share knowledge, and handle user requests. These roles enhance communication of user needs, support alignment between development and user requirements, and complement development-side user representatives. These findings contribute to a deeper understanding of user involvement in large-scale, distributed agile software development.

Texte intégralRésumé :
AbstractWith the mass application of virtualization, micro-services, and cloud-native technologies, the interaction between service entities through APIs has become a norm. Many platforms are still maintaining a large number of old APIs due to business needs. At the same time, many new APIs are gradually going online. Both of these statuses put forward higher requirements for API security. Focusing on old APIs’ security protection and other issues, this article starts from the process of asset discovery, vulnerability detection, and security auditing. Aiming at the problem of API asset discovery, this article summarizes the technical methods of automatically clustering unowned API assets using the characteristics of various commonly used APIs. Aiming at new API vulnerability detection, a security analysis method based on finite state machine is proposed. For the first time, the cross-network communication taint propagation based on dynamic taint analysis technology and system-level simulation technology is realized, enabling sensitive data flow tracing in API communication become feasible. We designed a flowbased API security audit system to improve automated API protection. Finally, We analyzed technical opportunities and challenges of API security in detail and prospected for API security research’s next direction and development trend.

Texte intégralRésumé :
Abstract Agility embraces changes in the functional and non-functional requirements. When the latter happens, the architecture needs to evolve, putting architectural refactoring in evidence. Microservices is an architectural style that enables more agility in a system’s architecture, as it favors the evolution of the system by adding new operations. But it also has its liabilities: the number of services can explode, with similar ones being created. Ultimately, that harms the system’s evolution and maintenance. This work addresses these challenges by proposing a catalog of architecture refactorings to promote reusability in Microservices. These refactorings target patterns that embrace data heterogeneity in the APIs and employ metadata to enhance messages and guide processing. We evaluated the catalog with case studies of three real-world applications and conducted change impact analysis in two scenarios: adding a new data provider, and adding a new processing algorithm. The results showed that embracing heterogeneous data in the API enables a more seamless addition of new data providers, and using metadata can strongly decouple the processing algorithms from the data they use. Furthermore, the results point to other improvements in observability, scalability, and infrastructure.

Texte intégralRésumé :
AbstractSoftware requirements specifications (SRS) serve as an important source of information for a variety of roles involved in software engineering (SE) projects. This situation poses a challenge to requirements engineers: Different information needs have to be addressed, which are strongly dependent on the particular role(s) that SRS stakeholders have within a project. This chapter summarizes the contributions of a thesis that aimed to address and reduce role-specific defects in SRS that negatively influence the efficient usage and acceptance of these documents. To achieve this goal, we collected empirical data about role-specific information needs in a series of empirical studies that served as a baseline for a secondary analysis toward the definition of role-specific views. Moreover, we realized a proof-of-concept implementation that is capable of generating role-specific views on SRS. The results of a case study revealed that role-specific views have the potential to efficiently support SRS consumers during the analysis of a given SRS. Besides conducting further empirical studies in industry, future work aims to foster cross-disciplinary collaboration and requirements communication, especially in agile teams. Thereby, we are exploring synergy potential with best practices from non-SE disciplines.

Texte intégralRésumé :
AbstractThe increasing prevalence of Artificial Intelligence (AI) in safety-critical contexts such as air-traffic control leads to systems that are practical and efficient, and to some extent explainable to humans to be trusted and accepted. The present structured literature analysis examines $$n = 236$$ articles on the requirements for the explainability and acceptance of AI. Results include a comprehensive review of $$n = 48$$ articles on information people need to perceive an AI as explainable, the information needed to accept an AI, and representation and interaction methods promoting trust in an AI. Results indicate that the two main groups of users are developers who require information about the internal operations of the model and end users who require information about AI results or behavior. Users’ information needs vary in specificity, complexity, and urgency and must consider context, domain knowledge, and the user’s cognitive resources. The acceptance of AI systems depends on information about the system’s functions and performance, privacy and ethical considerations, as well as goal-supporting information tailored to individual preferences and information to establish trust in the system. Information about the system’s limitations and potential failures can increase acceptance and trust. Trusted interaction methods are human-like, including natural language, speech, text, and visual representations such as graphs, charts, and animations. Our results have significant implications for future human-centric AI systems being developed. Thus, they are suitable as input for further application-specific investigations of user needs.

Texte intégralRésumé :
AbstractDistribution is a key aspect of insurers’ business models. Insurance companies use multi-channel and multi touch-point distribution methods to target their customers. Insurers must manage the distribution risk arising from actions of the distribution channel, which have the potential to impact the quality and volume of the insured portfolio, the insurer’s income-generating capacity, long-term financial sustainability and brand value. In this chapter we discuss the implications of the introduction of the Insurance Distribution Directive (IDD) on distribution risk management and on firm’s entire value chain. The expected impact of IDD main provisions (demands and needs analysis, suitability and appropriateness requirements, remuneration and incentive mechanisms, conflicts of interest dispositions, cross-selling, POG, information to customers, CPD) on product development, sales and distribution, underwriting and policy administration, claims, asset and customer management activities are analysed, considering the influence of digitalization on insurance distribution and value chain.

Texte intégralRésumé :
Abstract This paper presents how Romanian educational strategies are aligned with the policy statements of international organisations for future generations. The research hypothesis is that Romanian higher education institutions (HEI) are not ready to fulfil the needs of future generations. The paper reviews the educational competences of fourteen faculties of public administration and management from nine universities (state and private). The analysis is based on Kolb’s experiential learning cycle elements, and we identified whether educational competences referred directly to them or not. Our findings concentrate on the lack of recognition of experiential learning methods and the gap between the labour market requirements and the educational competences acquired in Romanian HEI. The methodology used to respond to the research questions mixes qualitative (strategies and literature review, structured interviews) and quantitative approaches (assessment of the curricula and information presented in the admission process by Faculties of Public Administration and Management).

Texte intégralRésumé :
The design of complex systems is based on the needs and expectations of multiple stakeholders. Analysing such elements and transforming them into a rigorous system specification is a long and demanding task. This research is interested in supporting engineers and other stakeholders in the specification of system requirements with a focus on requirement analysis. The paper presents an approach to conduct analysis of non-functional requirements in a way that benefits both the engineers involved in the development of the current system, and those who will need to make improvements to it. The approach includes suggestions towards a tool, a representation, and a method. The tool is a software tool that specialises in capturing decision rationale known as Decision Rationale editor (DRed); the representation is adopted from the IBIS notation; the method is based on a model synthesised from literature on requirement analysis.

Texte intégralRésumé :
In today's society, "phubbers" are flooding the corners of society. Phubbers are people who nowadays "look down at the screen" whenever and wherever they are, trying to fill up their fragmented time by staring at the screen. The increasing popularity of smartphones has made them an indispensable tool in the lives of phubbers, who rely on them to bring them a variety of needs to meet. The news of traffic accidents caused by immersion in cell phones is common. This is no longer an individual encounter, but a group rule, and phubbers do have visual information barriers in traffic scenarios. In addition, prolonged daily exposure to cell phones and over-stimulation of the brain can make concentration incomplete. The limit of forward flexion (the state where the chin touches the sternum) can only be 45° when the head is bowed. If the forward flexion reaches 30°, it can affect the cervical spine. If the cervical spine is in an abnormal stable state of extreme forward flexion for a long time, it can cause damage to the cervical spine. Therefore, it is of practical significance to propose corresponding design strategies for the safety hazards and visual information barriers that exist in the traffic scenes of the phubbers.This thesis adopts a combination of qualitative and quantitative research methods, firstly, based on the AEIOU analysis model and user behavior process, a specific analysis model is constructed for the behavior of phubbers crossing the road. It can make a more comprehensive analysis of the whole process of each contact point and crowd state and behavior in the scene, and the corresponding functional modules are derived. The functional modules mainly include the behavioral level, the physical and spiritual social level, and the environmental level. Among them, the behavioral level includes intersection reminder module, auditory reminder, remaining time reminder, and visual reminder within the line of sight of head down playing cell phone; the material and spiritual social level includes anxiety relief module, relief of unstable emotions, and personal safety module; the environmental level includes safe waiting area division, and obvious dynamic change stimulation. The Kano model was further applied to prioritize the functional modules, and the statistical analysis was used to determine the user-perceived importance and ranking of the listed functions, which finally led to the functional requirements of barrier-free crossing for phubbers. It provides a reference for future research on visual information accessibility design for phubbers and the development of accessible design for public transportation.

Texte intégralRésumé :
This paper focuses on the second step of a three-step design concept selection procedure: (step 1) identification and structuring of customer needs and constraints, (step 2) setting target product requirements using decision analysis, and (step 3) design concept selection using target product requirements as selection criteria. Particularly, this paper models and analyzes a decision problem of setting target product requirements by utilizing an influence diagram and a decision tree. Once the target product requirements are identified, engineers evaluate different design concepts in terms of how each concept satisfies the target product requirements. The next generation linear particle accelerator serves as an illustrative example.

Texte intégralRésumé :
Introduction. Grief and bereavement include cognitive, affective and physical dimensions. Pre- and post-grief manifest at different times of coping with loss and bereavement. Contextualisation of information behaviour studies and comprehension of contextual components e.g. temporal and spatial factors, progression and phenomenal contexts of grief is essential for information interventions. Although agreement on the meaning of context might continue to escape information behaviour researchers, widely cited interpretations of context might be used to analyse a selective body of literature to direct grief and bereavement information behaviour studies. Method. Interpretations of context and situation by Savolainen (temporal and spatial factors), Fourie (multiplicity) and Dunne (person-in-progressive-situation) are, selectively applied to a thematic content analysis of papers on grief and bereavement. Phenomenal context is analysed in more detail. Analysis. A thematic content analysis matrix was developed. Results. The analysis revealed a minimum of ten contextual components to consider in information behaviour studies of grief and bereavement. Conclusion. Information behaviour studies on grief and bereavement should acknowledge the diversity of contexts and contextual components that impact on information needs, unique requirements for information such as memorabilia, information processing and sharing of information.

Texte intégralRésumé :
Customer Value Chain Analysis (CVCA) is an original methodological tool that enables design teams in the product definition phase to comprehensively identify pertinent stakeholders, their relationships with each other, and their role in the product’s life cycle. By performing CVCA, design teams are better able to recognize diverse product requirements and their relative priority for undertaking Product Definition Assessment and downstream Design for X (DfX) tools, such as Quality Function Deployment (QFD) and Failure Modes and Effects Analysis (FMEA). This paper discusses the evolution of the CVCA in response to the need for a DfX tool which is able to delineate customer needs early in the product development process. A step-by-step guide clarifies the implementation of CVCA with an example. Further, three case studies highlight the tool’s broad utility and important features to support design decision-making, including: 1) confirmation of the product’s business model, 2) recognition of the critical stake-holders, and 3) clarification of the value proposition to be embedded in the product.

Texte intégralRésumé :
The requirements, issues and challenges of establishing a model-driven vehicle system engineering (MD-VSE) process are explored. The needs for new methodologies, processes and infrastructure to address complex system level design issues are highlighted. The problem is viewed from the perspective of the relation between vehicle engineering domains and vehicle attribute and function requirements. With this view, an incremental approach to establishing a MD-VSE process is outlined. The approach consists of developing modeling frameworks to address critical attribute and function trade-off scenarios. The modeling frameworks would allow more formal and up front optimization and sensitivity analysis than is currently realized. In order to sustain these frameworks, a modeling cascade process has also been outlined. This would place formal requirements on VED’s to deliver models to support the MD-VSE process.

American Society of Mechanical Engineers, 2015. http://dx.doi.org/10.1115/detc2015-47284.
Texte intégralRésumé :
This paper proposes a design development process to analyze and optimize the design of a brake rotor for a Formula Student Electric Vehicle so as to minimize its weight and reduce thermal stress by keeping the rotor within its operating temperature during the entire braking duration. In today’s world where lesser energy consumption is essential, regenerative braking plays an important role, and is also a factor in weight reduction of brake discs. Regenerative braking is an effective method to maximize brake disc’s life, minimize pad wear and extend working range of electric vehicles. The proposed technique consists of using a tire model and building mathematical models in a MATLAB environment to find transient vehicle speed, which in turn provides wheel loads, frictional torque, braking power and heat flux to the brake disc as a function of time. The heat flux to brake disc increases its temperature and is dissipated mainly through convection, which is also a time-dependent parameter based on air velocity. The entire transient heat transfer model, which also depends on the geometry, material of the brake rotor and mechanical boundary conditions is setup in ANSYS FLUENT and ANSYS Transient Structural and simulation results are presented. Stress fields for floating rotor and fixed rotor are compared since fastening techniques also play a crucial role. Disc brakes are used in almost all ground vehicles and thus, the given design process is vital as the work presented can be extended and modified as per requirements to incorporate the needs of the specific situations one needs to work upon.

Texte intégralRésumé :
This technical note (TN) will outline a framework to identify beneficial and cost-effective coastal beneficial use of dredged sediment (BUDS) projects. Creation of a BUDS framework that can be applied at scale will promote sustainable BUDS practices, facilitating the delivery of flood risk management, social, and environmental benefits while still fulfilling the US Army Corps of Engineers (USACE) navigation mission. This proactive forecasting approach uses multi-criteria decision analysis (MCDA) and optimization tools to balance tradeoffs between navigation dredging and BUDS goals over project-scale timespans. The proposed framework utilizes available tools to quantify ecological system evolution and current and future dredging needs to develop a systems-level approach to BUDS. Required data include current and future information on (1) existing and planned natural and created aquatic ecological systems, which may include natural and nature-based features (NNBFs), (2) dredging requirements and costs, and (3) aquatic system physical and environmental data.

Texte intégralRésumé :
The NIJ Technology Working Group’s Operational Requirements (TWG ORs) for Fire and Arson Investigation have included several scientific research needs that require knowledge of the thermophysical properties of materials that are common in the built environment, and therefore likely to be involved in a fire scene. The specific areas of research include: adequate materials property data inputs for accurate computer models, understanding the effect of materials properties on the development and interpretation of fire patterns, and evaluation of incident heat flux profiles to walls and neighboring items in support of fire model validation. These topics certainly address, in a concise way, many of the gaps that limit the analysis capability of fire investigators and engineers. Each of the three aforementioned research topics rely, in part, on accurate knowledge of the physical conditions of a material prior to the fire, how the material will respond to the exposure of heat, and how it will perform once it has ignited. This general information is required to visually assess a fire scene. The same information is needed by investigators to estimate the evolution and consequences of a fire incident using a computer model. Data sources that are currently most commonly used to determine the required properties and model inputs are outdated and incomplete. This report includes the literature review used to provide a technical approach to developing a materials database for use in fire investigations and computational fire models. A summary of the input from the project technical panel is presented which guided the initial selection of materials to be included in the database as well as the selection of test measurements.

Texte intégralRésumé :
In FY 2021, the 22 federal agencies that reported did not add or rescind any GUS in lieu of VCS, therefore there remains a total of 80 previously reported GUS in lieu of VCS still in use. This analysis does not reflect the use of standards by the Department of Defense (DoD) or the National Aeronautics and Space Administration (NASA) as they report their use of GUS on a categorical basis via a different reporting mechanism. Agencies demonstrate the effectiveness of the NTTAA and Circular A-119 by their continuous review of opportunities to rescind GUS in favor of using VCS, and their involvement with the private sector through the VCS process. These activities suggest that federal agencies are cognizant of the benefits of meeting their mission needs by actively seeking to use VCS developed by the private sector. In accordance with its coordination role as defined in the NTTAA and OMB A-119, NIST continues to assist federal agencies and their stakeholders with standards and conformity assessment information, program support, guidance, and policy concerns. NIST hosts http://standards.gov, which offers ongoing practical guidance and information needed by agencies to implement the NTTAA successfully and report standards activities as required by the NTTAA and OMB Circular A-119. This report fulfills the annual reporting requirements of both the NTTAA and OMB Circular A-119.

Texte intégralRésumé :
Swift changes in society, related to sciences technicians’ development, technologies, by the increase of general volume of information, pull out new requirements for maintenance, structure, and quality of education. It requires teachers to diversify a tool in the direction of the increase in possibilities of the use of mobile technologies and computer systems. Lately in the world, more attention spared to the use of mobile learning, which in obedience to «Recommendations of UNESCO on the questions of a policy in the area of mobile learning» foresees the use of mobile technology, both separate and together with other by informational computer technologies. [1]. Mobile learning allows using the open informational systems, global educational networks, unique digital resources which belong to different educational establishments and co-operate with each other. The use of existent educational resources and creation of own, based on the academic resources from informative space, allows to promote the interest of students to the study of physics, to take into account the individual features, and also features of region and framework of society of the country. During the last years in Ukraine competency-based approach to the organization of studies certainly one of basic. The new Education Act addresses the key competencies that every modern person needs for a successful life, including mathematical competence; competence in natural sciences, engineering, and technology; innovation; information and communication competence [2]. This further emphasizes the importance of providing students with quality physical education and the problems associated with it. Using mobile technology in professional teaching work, the teacher has the opportunity to implement the basic principles of the competence approach in teaching physics. An analysis of the data provided in the official reports of the Ukrainian Center for Educational Quality Assessment showed that the number of students making an external independent assessment in physics and choosing a future profession related to physics has decreased significantly. This is due to the loss of students' interest in physics and the complexity of the content of the subject, as well as the increase in the amount of information that students need to absorb. In this article, we explore the possibilities of mobile technology as a means of teaching physics students and give our own experience of using mobile technology in the process of teaching physics (for example, the optics section in primary school).

Sembler, Jose Ignacio, Diether Beuermann, Carlos Elías, and Cheryl Gray. IDB-9: Country Programming. Inter-American Development Bank, 2013. http://dx.doi.org/10.18235/0010515.
Texte intégralRésumé :
This paper analyzes whether IDB-9 requirements surrounding the country programming process of the Inter-American Development Bank (IDB, or Bank) are being implemented fully and effectively. The country programming process includes two documents: the Country Strategy, which provides a multiyear overview of the Bank¿s work program; and an annual document that lays out lending allocations and the work program. The main requirements of IDB-9 related to country programming are that Country Strategies include development and macro-fiscal frameworks, that they build on these frameworks and country dialogue to align country programs to country needs, and that they reflect country demand for the Bank¿s lending and nonlending products. The annual programming document is then meant to implement the program laid out in the strategy to ensure that the projects funded by the Bank are in line with country needs. OVE finds that the Bank¿s Country Strategies fulfill some but not all of the IDB-9 mandates. They provide a general description of the characteristics and development challenges in the country, including recent macroeconomic performance, as well as summary diagnoses of sector needs and possible areas of Bank intervention. But they do not generally articulate a strategic approach for the Bank in key sectors or discuss the implications of the macro-fiscal analysis on the role of IDB or the size of IDB lending allocations. They rarely discuss or build on past successes and failures of the Bank in selected areas of intervention, explore the Bank¿s comparative advantage, or fully incorporate relevant analytic work. They provide limited if any information on the NSG lending envelope or portfolio and thereby miss an opportunity to build on potential synergies between SG and NSG instruments. It is only by identifying the synergies between various Bank activities and instruments¿including SG and NSG lending, technical cooperation, and analytic work¿that the Bank can make the most of its resources and tap into its full comparative advantage. With regard to the annual programming process, it is common for projects to be approved and undertaken in sectors that were not envisioned in the Country Strategy, and annual lending allocations do not necessarily accord with the lending envelopes included in Country Strategies. Indeed, the criteria used to determine lending envelopes and annual allocations are not transparent and appear to be closely correlated to past disbursements. In addition, the annual nature of the programming process puts time constraints on loan preparation that hurry the process and lead to year-end bunching of approvals¿and possibly squeeze out time for needed analytic work as well as opportunities for careful discussion and review. In light of these findings, OVE suggests that (i) the Board and Bank Management undertake an in-depth exercise to revisit the Country Strategy guidelines and consider carefully the appropriate role and structure of Country Strategies and Country Program Documents going forward; (ii) the methodology for determining both lending envelopes in country strategies and annual lending allocations in country programs be made more transparent and the Operational Program Report presented to the Board show how those annual allocations relate to IDB-9 priorities and country needs; and (iii) the programming process be carried out on a rolling two-year basis (with the first year being binding and the second year showing notional allocations and work programs) to allow greater time for planning and executing loans and other Bank support.
