Papadopulos, Julien. « Utmaningar och möjligheter med distansarbete : En kvalitativ studie om kravanalys på distans ». Thesis, Linnéuniversitetet, Institutionen för informatik (IK), 2021. http://urn.kb.se/resolve?urn=urn:nbn:se:lnu:diva-106740.
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.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.

Wass, Sofie, et Camilla Nyberg. « Does IDA meet the requirements ? : Evaluating the method Information Demand Analysis ». Thesis, Växjö University, School of Mathematics and Systems Engineering, 2009. http://urn.kb.se/resolve?urn=urn:nbn:se:vxu:diva-2581.
Texte intégralRésumé :
This study aims to evaluate the use of the method Information Demand Analysis (henceforth IDA) against an analysis tool. To gain empirical understanding of IDA, the method will be applied to a cooperation process between two business organisations. The research questions of the study are to investigate what can be required of a method, to identify the information demand for the above mentioned cooperation process, and to identify the strengths and weaknesses of the use of IDA.
Based on a literature study an evaluation framework, which describes what can be required of a method, was developed. The evaluation framework resulted in an analysis tool, which consists of the elements: method content, method user, method context, method validation, the method creator’s requirements, and the wishes and expectations of the business organisations. The use of IDA implied scoping to delimit the problem situation and a workshop to identify the information demand. In order to gain an understanding of the use of the method IDA, and to identify the information demand, the method was applied to a cooperation process between Steel AB and Wood AB. The information demand was later represented in Extended Enterprise Modelling Language (henceforth EEML). Finally, we analysed if and how the elements in the analysis tool were reflected in IDA and identified the strengths and weaknesses of the use of the method.
The strengths of IDA are that it is general and applicable on different types of business organisations. Furthermore, it has well defined concepts and the possibility of selecting appropriate concepts ensures that it is applicable on different problem situations. The business organisations, which participated in the workshop, found that IDA resulted in a holistic view and increased the understanding for each other. The weaknesses of IDA are lack of documentation of explicitly defined steps, the implications for selecting certain concepts, guidance, and explicitly described notations. Concerning the involved roles, in IDA, we request a description of them, their responsibilities, and the needed knowledge sets and skills for using the method. Since IDA still is under development we had difficulties understanding how our outcome of the method should fulfil the purpose of IDA.

Texte intégralRésumé :
The technology revolution has transformed the way in which many organisations do their business. The resultant information systems have increased the decision making powers of executives, leading to increased effectiveness and ultimately to improved product delivery. The process of information systems development is, however, complex. Furthermore, it has a poor track record in terms of on-time and within-budget delivery, but more significantly in terms of low user acceptance frequently attributable to poor user requirements specification. Consequently, much attention has been given to the process of requirements elicitation, with both researchers and businessmen seeking new, innovative and effective methods. These methods usually involve large numbers of participants who are drawn from within the client and developer organisations. This is a financially costly characteristic of the requirements elicitation process. Besides information systems, the technology revolution has also brought sophisticated communication technologies into the marketplace. These communication technologies allow people to communicate with one another in a variety of different time and space scenarios. An important spin-off of this is the ability for people located in significantly different geographical locations to work collaboratively on a project. It is claimed that this approach to work has significant cost and productivity advantages. This study draws the requirements elicitation process into the realm of collaborative work. Important project management, communication, and collaborative working principles are examined in detail, and a model is developed which represents these issues as they pertain to the requirements elicitation process. An empirical study (conducted in South Africa) is performed in order to examine the principles of the model and the relationships between its constituent elements. A model of geographically distributed requirements elicitation (GDRE) is developed on the basis of the findings of this investigation. The model of GDRE is presented as a 3-phased approach to requirements elicitation, namely planning, implementation, and termination. Significantly, the model suggests the use of interviews, structured workshops, and prototyping as the chief requirements elicitation methods to be adopted in appropriate conditions. Although a detailed study of communications technology was not performed, this thesis suggests that each individual GDRE implementation requires a different mix of communication technologies to support its implementation.

Texte intégralRésumé :
This thesis states the tasks of the analyst: communicating with commercial customer to establish their requirements; reframing those requirements by negotiation in order that programmers can understand it to write the codes efficiently. Soft System Methodology (SSM) is an effective approach to identify the situation of the problem. In my thesis, I will improve a new business – oriented method that is called Process Improvement for Strategic Objectives (PISO) with SSM to make PISO have more efficiency and more quality. My first scientific contribution is to find the relationship between SSM and information system, explore how to adopt Soft System Methodology into a commercial information system analysis. Then I will do detailed research regarding how to improve PISO method with SSM.

Hughes, J. « The development of the GIST (Grounding Information Systems) methodology : determining situated requirements in information systems analysis ». Thesis, University of Salford, 1998. http://usir.salford.ac.uk/14678/.
Texte intégralRésumé :
This thesis develops a methodology for situated requirements determination in information systems analysis. The thesis challenges convention and adds to the body of knowledge in this area since the methods of the methodology are more usually associated with the social sciences. The role of the systems analyst and the nature of information systems as a distinct discipline form a major part of the thesis and the scope of this investigation includes an exposition of information systems methodologies in general and 'soft' methodologies in particular. A major element of the thesis is the empirical work carried out in which the researcher has undertaken two 'live' systems analysis studies using the methodology which has been developed in action supported by computer software for qualitative data analysis The results from the study are presented in terms of learning and are analysed to help answer the questions relating to the appropriateness of the methodology and the usefulness of the methodology for practising systems analysts. The research methodology used is action case and the appropriateness of this is examined in depth since studies of this type raise a number of questions relating to the validity of this type of research and the role of the researcher. The thesis draws together the different problems and questions that arise in order to produce a coherent, consistent and academically worthy account based upon the literature and empirical findings. In short the thesis addresses the basic issue that motivated its production, namely, how systems analysts faced with organisational complexity really find out what is going on. The outcomes of the research argue for a new role for the systems analyst as postmodern 'bricoleue and tentatively propose the usefulness of social science methods in information systems practice.

Abbas, Nada. « Information needs of gravel roads stakeholders : A case study to elicit the requirements of future users of a cloud-based information system ». Thesis, Linnéuniversitetet, Institutionen för informatik (IK), 2020. http://urn.kb.se/resolve?urn=urn:nbn:se:lnu:diva-97314.
Texte intégralRésumé :
Within any ecosystem, information needs are shared to be fulfilled and to support the ecosystem in a way or another. They are vital for designing appropriate information systems that will provide those needs. In this thesis, the gravel road ecosystem is studied, where efficient information sharing is not enabled due to the lack of appropriate information systems. Thus,when focusing on the gravel roads ecosystem, information plays a crucial role regarding the maintenance acts upon these roads. Moreover, not enough literature investigates theinformation needs of gravel roads stakeholders with the aim to improve the maintenance ofthese roads. Therefore, this thesis intends to elicit information needs of gravel road stakeholders by performing an exploratory case study. The case study forms a part of an ongoing project with the goal to build a cloud-based information system for a sustainable gravel road maintenance. Data were collected through telephone- and online-based interviews with several key stakeholders in Sweden and were thereafter structured through template analysis. The major findings were a set of information needs and several needed sensors within the pre-mentioned information system. This thesis concluded that the future cloud-based information system in the ongoing project is a useful system for sharing vital information among future gravel roads stakeholders, considering the variety of needed information that affects the maintenance of the gravel roads.Sustainable maintenance of gravel roads

Various approaches are proposed to manage enterprise information security risks and to assess its information security readiness. These approaches are, however, not adequate to manage information security risks, as all required information security components of its structural and procedural dimensions have not considered. In addition, current assessment approaches lack numerical indicators in assessing enterprise information security readiness. Furthermore, there is no standard approach for analysing cost versus benefit in selecting recommended protection measures. This thesis aims at contributing to the knowledge by developing comprehensive Enterprise Information Security Risk Management (EISRM) framework that integrates typical approaches for information security risk management, and incorporates main components of key risk management methodologies. In addition, for supporting phases of the proposed EISRM framework, analytical models for enterprise information security readiness assessment and cost-benefit analysis are developed. The practical evaluation, using the proposed enterprise information security readiness assessment model has been performed depending on a developed investigation form that used to investigate nine enterprises inside Saudi Arabia. The results demonstrate the effectiveness of the model in assessing and comparing enterprises information security readiness at all levels of the model, using numerical indicators and graphical representations. The EISRM framework and the analytical models presented in this research can be used by enterprises as single point of reference for assessing and cost effectively improving their information security readiness.

Texte intégralRésumé :
This thesis investigates how a web-hosted portal could be developed and designed in order to assist customer information updates in micro-enterprises in the ship broking business. Based on well-established system development theories and collected material, the web-hosted portal concept was developed. The development process included a case study at a ship broking company in Karlshamn, southern Sweden. Ship broking companies handle information as a mediator between other actors, thus the information becomes sensitive. In the ship broking business there is a constant need and flow of information. As the shipbrokers’ customers demand constant information 24 hours a day it is important to meet this demand in a service minded fashion. Today all customer updates are handled manually and are considered very time consuming and generate duplication of work. To solve these issues a possible solution could be to introduce information technology in the organisation. The introduction of information technology in the ship broking organisations has been slow. A contributing factor might be the widespread conservatism and resistance to changes in the ship broking business. The conclusions show the needs and demands for a web-hosted portal among shipbrokers and interested parties in the logistic chain. The result of the thesis should be considered as a foundation for further development and implementation of the concept.

This study attempted to ascertain what knowledge and skills are required for NUL librarians to meet the information needs of humanities undergraduate students in the digital era academic library environment. To address the objective of this study, the following research questions were generated: what are the library related information needs of NUL humanities undergraduate students in the current digital age?; what knowledge and skills are required of NUL librarians in meeting the library related information needs of humanities undergraduate students in the current digital age?; to what extent has technology affected the roles and functions of NUL academic librarians?; to what extent are NUL librarians readily adapting to and embracing technological changes affecting academic library resources and services?; and, what type of education and training are required for NUL librarians to effectively meet the information needs of humanities undergraduate students in the digital age academic library environment? The study was supported by organizational learning theory. It employed a convergent parallel mixed methods approach within a pragmativist paradigm for the collection of both quantitative and qualitative data to respond to the research questions guiding the study. A case study design was adopted in identifying humanities undergraduate students' information needs and concurrently ascertaining knowledge and skills requirements of NUL librarians. The target population included NUL librarians and humanities undergraduate students. Non-probability purposive sampling was employed to collect qualitative data (from the librarians) whist probability stratified random sampling was adopted to obtain quantitative data (from humanities undergraduate students). Data were collected via face-to-face semi-structured interviews with librarians and a structured questionnaire for students. In concluding, the study presents, inter alia, a blend of required disciplinary, generic and personal competencies for NUL librarians to meet the library related information needs of humanities undergraduate students in the current digital age. It recommends, inter alia, the adoption of effective organizational learning to build on NUL librarian's existing knowledge and skills so that they may more easily adapt to rapidly evolving technology and more fully meet the information needs of humanities undergraduate students.

Pettit, Alex Z. « Development and Validation of an Instrument to Operationalize Information System Requirements Capabilities ». Thesis, University of North Texas, 2014. https://digital.library.unt.edu/ark:/67531/metadc500066/.
Texte intégralRésumé :
As a discipline, information systems (IS) has struggled with the challenge of alignment of product (primarily software and the infrastructure needed to run it) with the needs of the organization it supports. This has been characterized as the pursuit of alignment of information technology (IT) with the business or organization, which begins with the gathering of the requirements of the organization, which then guide the creation of the IS requirements, which in turn guide the creation of the IT solution itself. This research is primarily focused on developing and validating an instrument to operationalize such requirements capabilities. Requirements capabilities at the development of software or the implementation of a specific IT solution are referred to as capabilities for software requirements or more commonly systems analysis and design (SA&D) capabilities. This research describes and validates an instrument for SA&D capabilities for content validity, construct validity, internal consistency, and an exploratory factor analysis. SA&D capabilities were expected to coalesce strongly around a single dimension. Yet in validating the SA&D capabilities instrument, it became apparent that SA&D capabilities are not the unidimensional construct traditionally perceived. Instead it appears that four dimensions underlie SA&D capabilities, and these are associated with alignment maturity (governance, partnership, communications, and value). These sub factors of requirements capabilities are described in this research and represent distinct capabilities critical to the successful alignment of IT with the business.

Holland, Jeremy David Hasse. « The requirements analysis & ; design for a clinical information system : a formal approach ». Thesis, City University London, 1995. http://openaccess.city.ac.uk/7705/.
Texte intégralRésumé :
Following a number of recent far-reaching reforms to the UK NHS, St Thomas' Hospital (where this work was based) introduced a management structure based on the 'Clinical Directorate'. In order to lessen the increased workload commensurate with this measure, it was decided at St Thomas' that a new type of information system - the Directorate Information System or DIS - would introduced. This system was to 'support the business of the clinical directorate'. As part of the DIS project, a small study was set up toinvestigate the problems associated with the introduction of such an information system, and to suggest a design. This thesis reports on the study. The design of information systems in general, and clinical information systems in particular, seems to be an extremely difficult endeavour: many systems development projects end in failure. It is widely considered that the problems lie in inadequate requirements analysis and specification: consequently it was here that the project concentrated most of its efforts. It was recognised that when in use, the terms, quantities, and entities stored and displayed by an information system are interpreted by its users as terms, quantities, and entities in the organisation that is being supported (also called the domain in the thesis). This is perhaps the fundamental requirement of an information system: that it represents the organisation and processes it is to support. To assess the degree to which a design satisfies this requirement entails the development and use of three descriptions, or theories. The first is the theory of the domain; the second is a theory, or specification, of the proposed information system; the third is a theory of the way in which the information system is interpreted into the domain - this is called the interaction theory and is a composition of the first two theories. By inspecting the interaction theory inadequacies in the representation of the domain by the information system can be identified and, if necessary, rectified. There are four ways in which we are encouraged to modify information system designs so that they more accurately reflect the behaviour of the domain. These are called the four developmental motives. Through the use of a well constructed interaction theory, and guided by the desire for system simplicity on one hand and the four developmental motives on the other, an improved information system design can be engineered. For an interaction theory to be constructed and provide useful insight, both the domain theory and the information system specification must be semantically rich. Conventional analysis notations are inadequate for the task: mathematics (in this case set theory) is needed to represent and explore the domain, the information system, and the interpretation of the latter into the former. The construction of a good domain theory is the hardest part of the process. Representing the organisation as it is perceived by workers (in this case clinicians) as a set theoretic construction is fraught with difficulties. However, the judicious use of an adaptation of the scientific method means that we can have increased confidence that the resulting description of the organisation is a reasonable one and is not merely a statement of the analyst's preconceptions and prejudices. The thesis describes in more detail the background to the project, the use of the scientific method to derive a domain theory, the construction of interaction theories, and the engineering of information systems through the use of the four developmental motives. This is done through the use of a large case study which presents, documents, and discusses the theories used in the Directorate Information System project, and describes their evolution.

Texte intégralRésumé :
This thesis explores how to design for the visually impaired. During the course of work, a literature study and interviews with blind and visually impaired people were conducted. The objective was to investigate what contextual information is wanted in new and unfamiliar spaces outside their home. The interviews also explored how they experience digital tools they are using today and what they think of the possibilities of voice and other user interfaces. The main finding from the study is that there are indications that multimodal interfaces are preferred. The interface should combine voice, haptic and graphics since the participants wanted to interact in different ways depending on functionality and context. Three main problem areas were identified, navigation, public transportation and shopping. Another result was that when developing for the visually impaired it should always be tested on people with a wide variation of vision loss to find the correct contextual information.

Texte intégralRésumé :

Irrigated agriculture is an essential component of global food production. In many regions of the world, and Asia in particular, groundwater is a major source of irrigation water. Over-pumping of groundwater aquifers has depleted storage in some areas. Quantification of the degree to which groundwater is being used unsustainably is critical to our understanding of the stability of irrigated agriculture. In this study, we investigate the feasibility of estimating groundwater storage changes using the water balance equation and currently available sources of global data. We employ multiple measurements of each water balance component and a constrained least squares estimation method in order to reduce uncertainties. Global datasets of precipitation, evapotranspiration, and runoff were obtained and evaluated for suitability for use in the water balance. In order to fill gaps in the existing data, we developed a new estimate of evapotranspiration based on NDVI measurements and land use information. Results are presented for the continental U.S. and for our study region in Asia. We also show that multiple regression of runoff against basin characteristics can provide additional runoff information in ungaged basins. The water balance can be used as a screening tool for poor quality data, and we are able to identify problematic basins in Asia. In addition, the least squares water balance estimator can be used to reduce the uncertainty in estimates of each component of the water balance.
(cont.) However, the uncertainty which remains in estimates of groundwater depletion precludes definitive statements about the sustainability of resource use in Asia for the time being. Groundwater depletion may be easier to detect using the water balance technique in drier climates, and forthcoming data products from advances in remote sensing may help to alleviate problems with the current data. However, we are unable to effectively evaluate the sustainability of groundwater use in many parts of Asia using the currently available data. This has implications for our ability to evaluate water and food security throughout the region.

Texte intégralRésumé :
Objective: This longitudinal cross-sectional study was designed to give a picture of the Northeast Tennessee rural health care providers’ information needs.
Methods: The population of this study was the health care providers in Northeast Tennessee outside the TriCities urban area. It is in the 15-county service area of the East Tennessee State University Quillen College of Medicine Library’s outreach and includes no one from a community larger than 25,000. The names of physicians were gathered from the Tennessee State Licensing Verification Database and personal knowledge of the librarians. The surveys were administered to registered nurses (RNs) from a list from the Tennessee Center for Nursing. A P=0.05 was obtained. The questionnaires were sent out by mail with a self-addressed stamped envelope. A cutoff date was set for 2 weeks for the return of the surveys. Surveys that came in after the cutoff date were accepted up to 1 month. A cover letter was included to explain the purpose of the survey. The data were analyzed in terms of central tendencies and dispersions of distributions. The data are displayed in the report by means of frequencies and percentages.
Results: This study compared rural information needs and practices in the same geographic area twelve years apart. This has given valuable information as to how the information needs and practices of this group have changed. This study will enable the librarians to change their outreach strategies to reflect the new reality.
Conclusions: Our purposes as medical librarians do not change. However, the environment of our service changes constantly. Longitudinal cross-sectional studies give the opportunity to obtain “snapshots” of a service environment to see how they change over time

Texte intégralRésumé :
Bibliography: pages [83]-89.One of the basic needs of both information systems practitioners and academics is in determining what skills and knowledge staff need in order to be able to perform adequately in their jobs (Nelson : 1991). This study was concerned with the information technology and information systems learning needs of two distinct classes of personnel; end users and information systems personnel. More specifically, it examines the perceptions that each group has of the other's particular deficiencies. It also compares the importance that each group accords to skill or knowledge in particular items for their counterparts, and how these expectations match their counterparts' own perceptions of item importance. The study was thus concerned with cross-perceptions; the perceptions that each group has of the other. This study examined these perceptions by means of the analytical survey method. The research instrument used was an adapted version of an instrument previously validated and used by Nelson (1991). The research instrument was completed by 168 employees within ten different organizations. The findings suggest that within six different areas of knowledge and skill both end user and IS personnel perceived their counterparts to be most deficient in the area of general IS knowledge; particularly in knowledge of the fit between IS and the organization, the potential uses of IS/IT within the organization, and in the use of IS for competitive advantage. In addition, both groups of personnel perceived their counterparts to be particularly deficient ii') their ability to communicate effectively. The deficiency in general IS knowledge was aggravated by the finding that both groups expect their counterparts to carry more of the responsibility for knowledge in general IS matters than their counterparts appear willing to assume. The implication of this mismatch of expectations is that it must first be resolved by clarifying the respective roles and responsibilities of both end user and IS personnel before the deficiencies themselves can be dealt with.

Texte intégralRésumé :
Objective: To determine what information training needs and behaviors medical residents have such as (1) information training provided by attending physicians, (2) formal evidence-based medicine (EBM) training programs, (3) information training provided by medical librarians, (4) preferred topics for information training, and (5) the desire to have a clinical librarian.
Methods: A survey analysis was conducted of 217 medical residents from the 2005/06 class in surgery, family medicine, internal medicine, obstetrics/gynecology, psychiatry, pediatrics, and pathology on their training needs and behaviors with a return rate of 48.4%. Quantitative analysis was performed with the SPSS (v. 14.0 for Windows) software program. The results were expressed in percents in graphical or tabular form. The data were analyzed using descriptive statistics (frequencies, mean, median, and mode) and inferential statistics (Mann-Whitney U test and chi-square test.)
Results: Sixty-one percent of residents indicated that they had received clinical information training from their attending physicians. Sixty-four percent of residents indicated they had formal EBM training in their program. Sixty-nine percent indicated they had received clinical information training from medical librarians. The top two training topics desired by residents were an overview of all available library resources and services and instruction on searching databases. Eighty-three percent of residents indicated that they would like a clinical medical librarian (CML) for their program. The Cramer’s V statistic indicated a moderately strong relationship between residency program and desire for a CML.
Conclusions: The desire for instruction by residents from librarians is strong. Medical librarians must more aggressively seek to provide instructional opportunities for medical residents. Librarians must periodically survey residents as to the content, time, and place where this instruction takes place so that it might be best utilized by residents.

Texte intégralRésumé :
This research explored the information needs of patient families and hospital staff at a pediatric hospital system in Dallas, Texas. Library statistics recorded in four hospital libraries from 2011 - 2013 were used to analyze the information requests from patient families and hospital staff. Crosstabulations revealed the extent to which patient families and hospital staff used the libraries to satisfy their information needs. The data showed that patient families used the libraries very differently than hospital staff. Chi-square tests for independence were performed to identify the relationships between the Classification (Patient Family, Hospital Staff) and two descriptors of information needs (Request Type, Resources Used). There were a total of 1,406 information requests analyzed. The data showed that patient families and hospital staff information requests differed greatly in the number of information requests, the type of information requested, the resources used and the time the library staff spent on the requests. Chi-square analyses revealed relationships statistically significant at the p < .05 level; however, the strength of the relationships varied.

Texte intégralRésumé :
In the Global War on Terrorism and future irregular battlefields, the Marine Corps will not only fight in large-scale conventional war against sizable military forces but it will also engage adversaries that utilize smaller sized units dispersed asymmetrically over vast geographical locations. To address this emerging threat, the Marine Corps is developing the Enhanced Company (EC) concept, with the aim of providing the company commander with the tools necessary to make isolated decisions in an increasingly complex battlefield. In order to make timely, independent decisions and maintain information superiority these widely dispersed units will require organic access to services normally provided by higher headquarters. The Marine Corps Warfighting Laboratory is working to enhance the decision-making capabilities of the infantry company through the development of the Company Level Intelligence Center (CLIC) and the Company Level Operations Center (CLOC). Current Marine Corps communications capabilities cannot meet the data demands of widely dispersed lower echelon units. The communications equipment organic to these units is mostly Line of Sight (LOS) technology. These systems limit the geographic dispersion of the units and are limited in data throughput capability. To allow for wider dispersion on the battlefield while providing the connectivity required for isolated decision making, these units require communications assets that are capable of operating Beyond the Line of Sight (BLOS) such as Satellite Communications (SATCOM) equipment. This thesis will seek to analyze the use of SATCOM in support of the Enhanced Company Concept in a FOB environment. Using a Limited Objective Experiment, the authors will test if SATCOM technology is sufficient to support Information Exchange Requirements (IERs) developed in the laboratory and validated with experience. Based on the outcome of the experiments the thesis will provide recommendations regarding the use of such technology.

Texte intégralRésumé :
The story of transport and accessibility problems in rural Australia is very similar to other wealthy countries with low rural densities and long distances such as the US and Canada ??? little or no public transport, very high levels of car ownership, and poor service provision. During the past two decades rationalisation and privatisation of services has led to the closure of many basic services in rural Australia. The withdrawal of services has necessitated longer distance travel for many rural residents ??? a problem which has been exacerbated by the rationalisation of public transport services. As a result there have emerged severe accessibility and mobility problems in rural areas, despite the presence of high levels of car ownership in such areas. In terms of rural transportation, the situation in Australia is characterised by two different features; first, poor public transport provision (or non-existence). Second; high levels of car ownership among rural residents. However, high levels of car ownership do not reflect high levels of prosperity; this is likely to indicate a situation of "enforced ownership" in response to declining levels of public transport provision. Furthermore, many rural residents neither own a car nor have access to a reliable public transport system due to socio-economic and location-based circumstances. Previous research has shown that these residents generally belong to groups who include the elderly, teenagers, students, Indigenous residents, unemployed persons and low-income households. Such groups have been termed transport-disadvantaged. The contention of this thesis, however, is that such groups are in a state of "transport need" given their range of transport related problems. This is one dimension of the accessibility problem in rural Australia, which has yet to be investigated. This thesis is concerned with the measurement of transport need through the development of several transport need indices using available census data. The key objective of this thesis is to investigate the relevance and suitability of need indices for identifying the relative spatial distribution of transport needs in rural areas. Geographical Information Systems (GIS) is used for the development, analysis and visualisation of the transport need index. This thesis examines transportation needs in rural NSW simply by measuring "demand" and "supply" components of transport. To measure the demand index, some socio-economic characteristics of population are involved including: the elderly, no or low car owning households, Indigenous people, students, children, unemployed persons, low-income households, and accessibility. A weight has been assigned to each component based on its relative importance among the other components. Weighted values are then standardised based on 100. To measure the supply index, six components, which represent the availability of various kinds of transport in rural NSW are involved and have been calculated by assigning weights and standardising to 100. These are: CountryLink rail services, CountryLink coach and bus services, Regional Services, Community Transport Program, Wheelchair taxi services, and School Buses. The final transport need for rural NSW is calculated by dividing demand index by supply index. It simply quantifies transportation needs across the rural Statistical Local Areas (SLAs) of NSW. In addition, this thesis discusses the potential and limitations of GIS and our transport need indices to be used as input to decisions about improvements in provision of services, and coordination of existing services to better meet identified needs, for the transport disadvantaged in rural NSW. In essence, this thesis is an attempt to make Australian transport and social services planners aware of the value of a need based transport-planning methodology.

Approved for public release, distribution is unlimitedWireless mesh mobile ad hoc networks (MANETs) provide the military with the opportunity to spread information superiority to the tactical battlespace in support of network-centric warfare (NCW). These mesh networks provide the tactical networking framework for providing improved situational awareness through ubiquitous sharing of information including remote sensor and targeting data. The Naval Postgraduate School's Tactical Network Topology (TNT) project sponsored by US Special Operations Command seeks to adapt commercial off the shelf (COTS) information technology for use in military operational environments. These TNT experiments rely on a variety of airborne nodes including tethered balloon and UAVs such as the Tern to provide reachback from nodes on the ground to the Tactical Operations Center (TOC) as well as to simulate the information and traffic streams expected from UAVs conducting surveillance missions and fixed persistent sensor nodes. Airborne mesh nodes have unique requirements that can be implemented with COTS technology including single board computers and compact flash.

Texte intégralRésumé :
Objective: To determine if the types of questions asked at the morning reports conducted by two East Tennessee State University Quillen College of Medicine residency programs, family medicine and pediatrics, and to determine if the databases used by clinical librarians to answer the clinical questions give the Quillen College of Medicine Library (QCOML) insight for future database purchases and end-user training.
Methods: A review of questions asked over a six-month period in two primary care morning reports was conducted. Each question was categorized according to the type of question (i.e., therapy, diagnosis, etiology, or prognosis) by two independent reviewers. A third reviewer was used to adjudicate differences in the two reviewers’ decisions. The search results from the morning report questions were also reviewed to see which databases were used to answer the clinical questions.
Main Results: The percentage of question types was compared between the two programs during the time period of January 1, 2007–June 30, 2007. For every foreground question, the question was then classifi ed as therapy, diagnosis, harm, prognosis, or other. Each morning report then had their questions broken down into a percentage to show how many of each type of question was asked. The results of the questions were analyzed to see which databases were used in answering the questions. The residency programs were then compared to see if any differences existed between them.
Conclusions: The analysis will serve as a gauge for the type of training needed or desired by the residents. The data show an overview of the questions asked that will further aid the QCOML librarians in determining databases and resources that will be most useful to the residency programs.

Texte intégralRésumé :
This research compared the employment of the skills and attributes needed by information systems security professionals in an information systems security work environment with those taught in NSA Centers of Academic Excellence in Information Assurance Education. Using two surveys the goal of this research was to determine if the skills and attributes identified in the CISSP were employed in an information systems work environment and if these skills were taught in colleges and universities designated as NSA Centers of Academic Excellence in Information Assurance Education.
The skills and attributes within the10 domains of the CISSP were identified by 23 questions contained in two surveys, one to information systems security professionals working in the field and one to information systems security faculty in NSA designated Centers of Academic Excellence in Information Assurance Education. The CISSP domains cover the following areas of information security responsibilities: 1) Access Control Systems and Methodology, 2) Telecommunications and Network Security, 3) Security Management Practices, 4) Applications and Systems Development Security, 5) Cryptography, 6) Security Architecture and Models, 7) Operations Security, 8) Business Continuity Planning and Disaster Recovery Planning, 9) Laws, Investigations, and Ethics, and 10) Physical Security. The CISSP domains were chosen as the defining criteria for the development of the operational definitions after an extensive review of literature in the field of information security.
The surveys were developed over three phases: the pilot phase, the validity phase, and the reliability phase. The breakdown of the domain descriptions into questions was accomplished during the pilot survey phase. Requests for participation in the survey were e-mailed to 800 information systems security professionals and 321 information systems security faculty. There was a 67% information systems security faculty response rate and a 20% information systems security professional response rate.
This research indicated that information systems security professionals working in an information systems security work environment employed or addressed the skills and attributes identified in the 10 domains of the CISSP. This research also indicated that the skills and attributes taught in the curriculum of NSA Centers of Academic Excellence in Information Assurance Education had no association with the skills and attributes employed, or addressed, by information systems security professionals in an information systems security work environment. There was one exception, Domain 4, Applications and Systems Development Security, which indicated there was an association between how the skills and attributes were employed in an information systems security work environment and were taught in NSA Centers of Academic Excellence in Information Assurance Education.
The findings of this research can be used as a baseline to develop information systems security curriculum. Further research is needed to determine the differences, if any, in the skills and attributes identified in the various information security certifications, the correlation between the skills and attributes identified in each of the information security certifications, and any differences in the employment of these skills and attributes between certified and non-certified information systems security professionals.

Texte intégralRésumé :
With growing markets and customers being geographically spread out, more pressure is put on a company’s logistics processes and their inventory structures are becoming more complex. This puts more pressure on the inventory control solution provided by a company like IFS, that supports their customers with inventory control through the Inventory Planning and Replenishment module in IFS Applications. As their customers’ supply chains grow larger, their inventory structures become more complex the next step is to find a solution for the IPR module more suitable in a called multi-echelon structure, i.e. several tiers of stock locations, such as local, regional and central warehouses. The purpose of this study is to compare a reorder point model with a solution suitable in a multi-echelon setting and investigate how they are able to manage uncertainties with service level targets. A literature study was performed, to find previous research on inventory control in multi-echelon inventory systems. In the literature study, the importance of coordination and information sharing between the echelons was emphasized and used as a focus when finding a suitable multi-echelon model. To answer the purpose a theoretical model was formulated from the findings in previous research, with a replenishment method suitable in a multi-echelon environment. The inventory control models also included lot sizing method and a safety mechanism, where the difference between the models were their respective replenishment policy. The theoretical model was based on the replenishment method Distribution Requirements Planning (DRP), as it enables information sharing, coordination and synchronization of the supply chain, while the other inventory control model uses the Reorder Point method (ROP). As information sharing was emphasized in previous research on multi-echelon systems, and the main difference between the two inventory control models is the information sharing in the DRP model, the important question to be answered with the comparison is; what effects and benefits can be achieved through information sharing in a multi-echelon inventory system? The two inventory control models were then simulated in Excel and exposed to even demand and seasonal variations in an inventory structure with three echelons and four sites, see figure below. When analyzing the results three evaluation criteria were used; difference in service levels, average inventory levels and if there were signs of overstocking in the regional and central warehouse, i.e. if the system was exposed to the bullwhip effect. The analysis was carried out based on the criteria above and divided into three sections. First, differences between the models for even demand were investigated. The same procedure followed for seasonal demand, identifying differences and what caused them. Findings were then summed up at the end of the chapter. For even demand, differences were small and sharing information does not give large benefits. Under seasonal demand though, sharing information proved to be very beneficial, reducing average inventory held in the system by 60%, compared to not sharing information. This because sharing information together with synchronizing eliminates the bullwhip effect. By testing different standard deviations, changing lead times and order quantities, using forecast or being blind to forecast, the robustness of the conclusions drawn from the analysis was put to the test. Carrying out a sensitivity analysis on the models served two purposes. First, finding more evidence promoting the benefits of synchronizing the supply chain and how important it is that the shared information is correct, otherwise the benefits are reduced. The second purpose was to validate that the models performed as expected when changing input data. The conclusions were the following: Information sharing enables synchronization of the supply chain Synchronization allows for reaching higher service levels with lower inventory levels Findings suggest that by sharing information, which must be the first step, synchronizing the inventory system is possible. It is the synchronization that creates the real benefits, such as higher service levels and lower inventory levels. However, the quality and accuracy of the shared information was found to play an important role. Sharing inaccurate or wrong information increase the risk of the system starting to suffer from the bullwhip effect, resulting in higher inventory levels and lower service levels.

Texte intégralRésumé :
Since the first lines of code were introduced in the automotive domain, vehicles have transitioned from being predominantly mechanical systems to software intensive systems. With the ever-increasing computational power and memory of vehicular embedded systems, a set of new, more powerful and more complex software functions are installed into vehicles to realize core functionalities. This trend impacts all phases of the system development including requirements specification, design and architecture of the system, as well as the integration and testing phases. In such settings, creating and managing different artifacts during the system development process by using traditional, human-intensive techniques becomes increasingly difficult. One problem stems from the high number and intricacy of system requirements that combine functional and possibly timing or other types of constraints. Another problem is related to the fact that industrial development relies on models, e.g. developed in Simulink, from which code may be generated, so the correctness of such models needs to be ensured. A potential way to address of the mentioned problems is by applying computer-aided specification, analysis and verification techniques already at the requirements stage, but also further at later development stages. Despite the high degree of automation, exhaustiveness and rigor of formal specification and analysis techniques, their integration with industrial practice remains a challenge. To address this challenge, in this thesis, we develop the foundation of a framework, tailored for industrial adoption, for formal specification and analysis of system requirements specifications and behavioral system models. First, we study the expressiveness of existing pattern-based techniques for creating formal requirements specifications, on a relevant industrial case study. Next, in order to enable practitioners to create formal system specification by using pattern-based techniques, we propose a tool called SeSAMM Specifier. Further, we provide an automated Satisfiability Modulo Theories (SMT)-based consistency analysis approach for the formally encoded system requirements specifications. The proposed SMT-based approach is suitable for early phases of the development for debugging the specifications. For the formal analysis of behavioral models, we provide an approach for statistical model checking of Simulink models by using the UPPAAL SMC tool. To facilitate the adoption of the approach, we provide the SIMPPAAL tool that automates procedure of generating network of stochastic timed automata for a given Simulink model. For validation, we apply our approach on a complex industrial model, namely the Brake-by-Wire function from Volvo GTT.VeriSpec

Texte intégralRésumé :
Philosophiae Doctor - PhDA review of the literature has shown that there is a lack of mental health information on which to base planning of mental health services and decisions concerning programme development for mental health services. Several studies have indicated that the use of an evidence-based health information system (HIS) reduces inappropriate clinical practices and promotes the quality of health care services. This study was aimed at developing a framework for a district-based mental health information management system, utilising the experiences of health care providers and caregivers about a district mental health information system (DMHIS). Activity Theory was used as the philosophical foundation of the information system for the study. A qualitative approach was employed using semi-structured individual interviews, Focus Group Discussions (FGDs), systematic review and document analysis. The intervention research design and development model of Rothman and Thomas (1994) was used to guide the study, which was conducted in the Cape Town Metropole area of the Western Cape. A purposive, convenient sampling method was employed to select study participants. Ethical clearance for the study was obtained from the University of the Western Cape, and permission to use the health facilities from the Department of Health. The data collection process involved 62 individual interview participants, from mental health nurses to district health managers, health information clerks, and patient caregivers/families and persons with stable mental conditions. Thirteen caregivers took part in the FGDs. Document review was conducted at three community mental health centres. The data were analysed manually using content analysis. Core findings of the interviews were lack of standardized information collection tools and contents for mental health, information infrastructure, capacity building, and resources. Information processing in terms of collection, compiling, analysing, feedback, access and sharing information were the major problems. Results from document analysis identified inconsistencies and inaccuracies of information recording and processing, which in turn affected the quality of information for decision making. Results from the systematic review identified five functional elements: organizational structure; information infrastructure; capacity building; inputs, process, output and feedback; and community and stakeholders’ participation in the design and implementation of a mental health information system (MHIS). The study has contributed a framework for a DMHIS based on the findings of the empirical and systematic review. It is recommended that there is a need to establish a HIS committee at district health facility level for effective implementation of the framework and quality information processing. There is a need to ensure that staffs have adequate knowledge and skills required for effective implementation of an information system. It is recommended that higher education institutions include a course on HISs in their curriculum. It is suggested that the South African Mental Health Policy be reviewed to include an MHIS and ensure involvement of the community and stakeholders in this system as well as adequate budget allocation.

Texte intégralRésumé :
Poor communication due to cultural differences between IS developers and system users has been cited as one reason why user requirements are not captured to the necessary level of detail and completeness, resulting in lower levels of system usability. This project set out to (a) better understand the nature of the 'gap' that apparently exists between users and developers of systems, especially in relation to the gathering of user requirements, (b) examine the role of the technical writer in relation to Hirschheim and Klein’s (1989) paradigms of the Analyst as Systems Expert and Analyst as Facilitator, (c) explore whether a system can be made more usable (as defined by the SOLE model) by the technical writer acting as a facilitator between user and developer during requirements gathering, and (d) explore factors which influence the problem of developer and user resistance to existing integrative processes. To these ends, an action research project was performed in which the researcher does the work of a technical writer on a commercial software development project in which he is to develop a statement of user requirements after facilitating communication between the project stakeholders, including IS developers and users. The research is designed to allow the researcher to outwardly act in the capacity of a technical writer performing a commercial contract, such that to the client he did not appear to be other than a technical writer. Hence the research site could have been any organisation wanting a technical writer to develop the user requirements for a software development project. The research site is the Energy Trading Department a leading retailer of electricity and gas in Australia. EnergyCorp had been formed some two years earlier to capitalise on newly deregulated markets. The organisation's annual sales at the time were in the region of A$1.5 Billion.Thesis (PhD Doctorate)
