    MAKING SENSE OF DIGITAL FOOTPRINTS IN POLICE PRACTICEManuscript (preprint) (Other academic)
    Abstract [en]

    Purpose Digital footprints are yet another weapon in law enforcement but have so far gained limited attention in research on police practice. Here we conduct an analyse of how a small police task force has managed to make sense of a large set of digital footprints. The aim is to increase the knowledge about the role digital footprints play and how these footprints are captured and managed during a 21st century criminal investigation.

    Methodology A case study approach have been applied and the theory of sensemaking as foremost an analytical lens helping the data analysis with a goal to better understand how the police officers worked in the chosen case study.

    Findings The use of large sets of digital footprints in the police investigations is a sensemaking process, and the use of digital footprints exists in two temporal structures. In the pre-arrest(1) the use of digital footprints is characterized by sensemaking, i.e. the police officers use the footprints as triggers to traditional police work to understand what is going on. In the post-arrest(2) the use of digital footprints is characterized as evidential aggregation, and analyzing and validating of digital footprints with those collected in previous temporal structure.

    Value Knowledge generated from this research gives design implcations for information system that not only fulfil the needs in police practice on a general level but in the actual work of capturing and managing digital footprints. The article also provides knowledge on how digital footprints are forming police practice in 21st century.

    A Parameter Tuning Framework for Metaheuristics Based on Design of Experiments and Artificial Neural Networks2010In: Proceeding of the International Conference on Computer Mathematics and Natural Computing 2010 / [ed] B. Brojack, WASET , 2010Conference paper (Refereed)
    Abstract [en]

    In this paper, a framework for the simplification andstandardization of metaheuristic related parameter tuning by applyinga four phase methodology, utilizing Design of Experiments andArtificial Neural Networks, is presented. Metaheuristics are multipurposeproblem solvers that are utilized on computational optimizationproblems for which no efficient problem-specific algorithmexists. Their successful application to concrete problems requires thefinding of a good initial parameter setting, which is a tedious andtime-consuming task. Recent research reveals the lack of approachwhen it comes to this so called parameter tuning process. In themajority of publications, researchers do have a weak motivation fortheir respective choices, if any. Because initial parameter settingshave a significant impact on the solutions quality, this course ofaction could lead to suboptimal experimental results, and therebya fraudulent basis for the drawing of conclusions.

    Hazards and Quality Control in Humanitarian Demining2018In: International Journal of Quality & Reliability Management, ISSN 0265-671X, E-ISSN 1758-6682, Vol. 35, no 4, p. 897-913Article in journal (Refereed)
    Abstract [en]

    The purpose of this paper is to discuss the adequacy of International Mine Action Standards 09.20 (IMAS 09.20) and the used standards ISO 2859 in the context of demining. The authors show how the actual quality level acceptable quality limit (AQL) significantly affects the average total quality cost for one lot with a single sampling plan and, consequently, the average total quality cost, and as AQL increases, the cost of rejecting a lot and the cost of sampling increase. The sampling plans for demining are not always optimal given economical and other concerns and that other mechanisms should be considered. Addressing opportunity costs for adopting wide samplings plans instead of clearing uncleared land per default, as well as balancing producer and consumer consequences seems, therefore, to be highly relevant from a socio-economical perspective. The general understanding of quality management and the systems involved are limited within the mine action sector. IMAS and most national mine action standards provide only a fairly narrow description of the issue. This implies that the field is missing opportunities to achieve efficiency and effectiveness, as well as to learn from and improve upon past experiences. The authors demonstrate herein that sampling provides little additional confidence as to whether a particular area is free from explosive hazards and substantial savings can be made compared to the current practice.

    Fear, Greed and Lack of Trust in Online Financial Trade2017In: Journal of Administrative Sciences and Technology, ISSN 2165-9435, article id 106163Article in journal (Refereed)
    Abstract [en]

    Trust is a crucial component in business relations, and also a precondition for people’s adoption of electronic services. This study addresses challenges regarding trust in online financial trade. Results indicate that brokerage companies acting in a dishonest way, along with dominant patterns of fear, greed and lack of knowledge and awareness among clients, lead to frequent losses of money. Which leads to a lack of trust in brokers, brokerage companies and the business domain. The way technology is used increases the challenges of risk and an unequal relation between client and brokerage companies. Self-ethnography has been used as a method, where observations, interviews and conversations were performed. Suggestions are to do further research in order to identify how mechanisms for trustworthiness, accountability and transparency can be created in the business domain, in which management of records will play a central role.

    Records roles in Corporate Sustainability Reporting: An explorative study of corporate sustainability reporting from an archives and information science perspective2019Independent thesis Advanced level (degree of Master (Two Years)), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Calls for more responsible companies, have led to initiatives and legislations of sustainability reporting, in order to improve corporate transparency and accountability regarding companies economic, environmental and social impact.

    The aim of the research was to explore records roles in corporate sustainability reporting, which is discussed from an archives and information science perspective. Records are regarded as evidence of business activities and therefore crucial to accountability and decision-making processes. A sustainability report is a record, and records are also used to create a sustainability report.

    The thesis is based on a qualitative explorative methodology with interviews as data gathering technique. Interviews were carried out with four employees at three different companies who work with sustainability reporting, a sustainability consultant who works with sustainability reporting, and an auditor who assesses the  companies´ annual and sustainability reports. The interviews have addressed records’ role in different aspects of sustainability reporting, exploring how sustainability reports are created, used and pluralized. As well as how the records, generated as an effect of the reporting process, are used, what impact they have on the business and efficiency of the process. The thesis also explore respondents´ perspectives on reliability and credibility of the reports in relation to records qualities. Results from the interviews have been analysed with the lens of Records Continuum Model and the ISO standard for records management, ISO 15489-1:2016.

    Results show that records are key assets that provide evidential information that enables different functions and benefits –both to companies that report and to stakeholders. Primary benefits of the reporting that have been emphasized are that it enables transparency and accountability, informed decision-making, management of risks, compliance with legislation, ability to demonstrate corporate responsibility and meeting sustainability goals, greater business efficiency, evidence-based analysis and development activities, formation of business culture and identity, and protection of corporate and collective memory about the corporates’ work regarding sustainability. Records are also valuable assets for governance and continuous improvements. It enables to monitor trends and assessment on how the company meets its targets.

    The thesis gives an increased understanding of records’ role in a socio-economic context. It also suggests some areas for further research and development in order for sustainability reporting to further support a sustainable development. One of the major tasks would be to make pluralization of sustainability-related records more efficient, in order to facilitate further utilization of the information. This may enhance corporate accountability and decision making based on sustainability criteria, and would make the work more efficient for companies. The global records governance environment can be improved further, in order to support  global sustainable development. Important is also to raise awareness about the role of trustworthy records.

    Trade, Trust and Information Power - In Transition to Sustainability2017 (ed. 1)Book (Other academic)
    Abstract [en]

    Trade, Trust and Information Power. Lessons learned from Online Trade. This is a book about how trust is used, misused and shaped in an online financial context. The author also suggests ways forward for the financial markets, pointing towards client-oriented e-financial services. Digitalization both challenges and opens up new possibilities to perform financial activities. Which also shapes relations of power in new ways. Along with other challenges such as climate change, this requires of us to consider how we want to perform human activities in a sustainable way. 

    Results based on an ethnographic study indicate that individuals are very vulnerable in a global digital market place, and the means for trustworthiness at different levels are insufficient, exposing individuals to high risks and uncertainty of who is actually to trust. One important conclusion is that in order to be able to work for the benefit of many, such a system needs to ensure trust. And that digital records and archives have a crucial role in realizing this.

    Ekonomiskt värde av information2017Report (Other academic)
    Abstract [sv]

    Information är en av Trafikverkets resurser och dess värde kan uttryckas på olika sätt och ha olika innebörd för olika aktörer vid olika tidpunkter. Informationen kan ha direkta ekonomiska värden, men värdet kan också uttryckas i dess betydelse för en långsiktig resursplanering och ekonomihantering.  Informationen  kan även bidra till arbetssätt som hushållar med skattemedel, och skapa  samhällseffekter inom t.ex  säkerhet och miljö. Vi har i den befintliga studien bland annat utgått ifrån standarden ISO 30300 som menar: 

    ”Att skapa och hantera verksamhetsinformation ingår i varje organisations aktiviteter, processer och system. Detta bidrar till effektivitet i verksamheten, ansvarstagande och riskhantering och till att verksamheten upprätthålls. Det gör det även möjligt för organisationer att se det värde som finns i informationsresurser som verksamhetstillgångar, kommersiella tillgångar och kunskapstillgångar, och bidra till att bevara det kollektiva minnet, som svar på utmaningar från den globala och digitala omvärlden” (ISO 30300, sid. iv). 

    I denna studie har vi valt att undersöka hur informationshanteringen, med fokus på ekonomirelaterad information, stödjer det pågående arbetet med ett livscykelperspektiv på anläggningen. Bakgrunden är Trafikverkets ambitioner att skapa en helhetssyn över anläggningens kostnader genom hela livscykeln. Och därmed också hur den ekonomiska redovisningen relaterar till annan information. Studien baseras på intervjuer med i huvudsak medarbetare på Trafikverket, men även vissa andra nyckelpersoner. Personer från följande funktioner och arbetsfält har intervjuats:  CoClass, BIM, ANDA/GUS, Öppna data, Informationsutbyten, Informationsförvaltning, Ekonomi, Ledningssystem, IT-strategi, Kontrakt och juridik, LCC, Internrevision, Riksrevisionen, Transportstyrelsen och Näringsdepartementet.

    Disagreement Constrained Action Selection in Participatory Portfolio Decision Analysis2016In: International Journal of Innovation, Management and Technology, ISSN 2010-0248, Vol. 7, no 1, p. 1-7Article in journal (Refereed)
    Abstract [en]

    In some portfolio decision problems it is not possible or interesting to constrain portfolios with a monetary budget. Instead it might be of interest to investigate how disagreement among a group of decision makers or stakeholders can be used as a constraint, and how this affects the portfolio composition. In this paper we present complementary decision evaluation methods for group portfolio decision analysis in situations where the stakeholders have conflicting preferences. The approach supports the analysis of a portfolio of planned actions in urban planning when a large group of stakeholders have inconsistent opinions with respect to the performance of each action. The group of stakeholders is, for each criterion, partitioned into two disagreeing groups based upon their views on the actions' performance. The distance between these two groups is then measured. An action's aggregated disagreement taking into account all criteria is then used as the action's associated resource constraint, and portfolios can be generated by solving a sequence of Knapsack problems. The robustness of the portfolios can be further evaluated with an a priori sensitivity analysis. The suggested approach supports decision makers by elucidating how the portfolio composition changes when the actions' aggregated disagreement increases.

    Elektroniska signaturer: -      ”Det kommer ju rasande snabbt det här.”2019Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    För en arkivarie är autenticitet en viktig del i arkivet, att kunna bevisa olika typer av informations äkthet. I takt med att tekniken utvecklas kommer också nya möjligheter. Möjligheterna kommer tillsammans med frågor och diskussioner om hur detta ska gå att bevara den dagen informationen ska arkiveras.

    Att kunna signera en handling på distans öppnar upp möjligheter för ett snabbare och mer flexibelt arbetssätt. I vissa fall är det även säkrare. Det kan spara tid, kostnader och ge medborgare, företag och myndigheter alternativ till vad som krävs för en handskriven signatur. Frågan är hur långt myndigheter har kommit i användningen av dessa signaturer och hur de hanteras när de når arkivet. Elektroniska signaturer kan ge verksamheter en chans till ett smidigare sätt att arbeta, men de innebär också vissa utmaningar när de ska hanteras.

    Den här uppsatsen är en studie av olika verksamheters arbete kring ämnet elektroniska signaturer. Resultatet kommer från intervjuer med fyra olika myndigheter och totalt sex respondenter där jag frågat om deras hantering av elektroniska signaturer i dagsläget, vad de tror om utvecklingen samt vilka utmaningar de ser. Resultatet visar på en variation i arbetet kring dessa frågor och även olikheter i vilka behov man har av utveckling och projekt angående dessa signaturer.

    Archivists 2.0: redefining the archivist´s profession in the digital age2012In: Records Management Journal, ISSN 0956-5698, E-ISSN 1758-7689, Vol. 22, no 2, p. 98-115Article in journal (Refereed)
    Abstract [en]

    Purpose - public organizations are investing in e-government development and e-services to improve the interaction and services to the citizens. Archivists need to  act more pro-active to capture and manage records in order to be accessible both in the present and in the long-term. Archivists need to understand the conceptual context and business processes in which the records are created. This study aims to focus on an ongoing process within a specific context, which may have direct, but also future implications for archivists`professional identity. Professional identity is understood as a sense of shared understandings an skills, experiences, common way of perceiving problems and their possible solutions. This study is meant to answer the overall research question and sub questions: What is the status of archivist professionals`positions and practice within public organizations? What organizational effect has the change from paper-based to electronic record keeping had on archivists`professional positions and practice within organizations? How do archivists perceive themselves in their professional roles, i.e. identity? Are there any critical competence issues that need to be solved that are connected to new requirements in working methods related to electronic record keeping? and How do archivists define their skills and working performance?

    Design/methodology/approach - The data presented and analyzed in this article are based on a literature review and an empirical study. The literature covers areas related to archivists`professional practice and future role. The empirical study is based on interviews with nine municipality archivists at nine different Swedish municipalities identified by the Swedish Association of Local Government and Regions as "good example" e-government municipalities. All interviews were undertaken during January and March 2011.

    Findings - The findings provide information on how archivists define their current and future professional role in relation to the organization and the development of information technology: the status of archivist professionals`positions and practice, for example, within public organizations. It explores the importance of strategic approaches to managing electronic records - from their creation throughout their whole existence, including long-term preservation - and considers necessary changes to the professional image and the skills they need.

    Orginiality/value - This article will be of interest to record keeping practitioners working in the shift to e-government in local contexts and also to educators, as there appears to be a shift in the skills and knowledge required by those working in local government.

    Archivists: A Profession in Transition?2012In: Professions & Professionalism, ISSN 1893-1049, E-ISSN 1893-1049, Vol. 2, no 1Article in journal (Refereed)
    Abstract [en]

    E-government development has put pressure on public organizations to work with electronic information. Records from complex e-government services have to be captured and managed in order to be accessible both in the present and in the long term. The data and analysis presented is based on a multiple case study of nine Swedish local governments (municipalities) identified as good ex-amples of best practice of e-government. An analytical model for recordkeeping awareness in three arenas: the legal, the political and the workplace has been created in order to identify how political decisions and new technology impact on professional archivists’ practice and status. The research findings demonstrate a gap between the legal and workplace arenas in both directions caused by lack of recordkeeping awareness primarily within the political arena. Archivists´ profes-sional status seems to be limited, which opens up possibilities for other profes-sional groups to replace them.

    E-government Development and Recordkeeping: A Comparative Study of e-government Best Practice in Swedish Municipalities2011In: iRMA Information and Records Management Annual 2010, ISSN 1836-3202, p. 83-94Article in journal (Refereed)
    Abstract [en]

    While information technology plays an important role in the delivery of e-government services there are other issues and processes that are of equal importance to successful e-government programs, namely the appropriate consideration of laws and regulations, sound business processes and change management. Records are also an important element of e-government as they support and demonstrate accountability and transparency and are a source of information for the citizens. In Sweden, the documents produced by public organisations are official records, and Swedish citizens are entitled to free access to them. These official records have been defined as an organisation’s archives.

     

    During the last 10 years, there have been many government programs and initiatives in Sweden aimed at achieving world class practices in e-government. Given that records are a part of e-government, this paper addresses whether or not consideration has been given to the role and importance of recordkeeping in developing best practice e-government. The specific context for this study is local government municipalities as the aim of world class, or e-government best practice, includes this level of government in Sweden. In particular, the paper investigates whether or not the municipalities that exhibited best practice in the delivery of e-government services have embraced recordkeeping as important to their strategic development. If so, to what extent have recordkeeping principles and practices been incorporated in the processes? 

     

    The paper focuses on the establishment of policies and business process descriptions such as retention and disposal schedules, preservation plans, the use of electronic records and competence issues. The underlying assumption is that municipalities that are good examples of e-government development are aware of the recordkeeping expertise, involve the archivists in working strategically with mapping processes, and have established routines, policies and guidelines for recordkeeping.

     

    The study presented in this paper is part of a larger body of research that is still in progress. This research aims to contribute to a better understanding of the importance of recordkeeping competence as a valuable component of best practice in e-government implementation. It also aims to identify recordkeeping challenges related to e-government development and electronic recordkeeping.

    Examining the use of core terms in a records appraisal context: two Swedish examples2017In: Tidsskriftet Arkiv, ISSN 1891-8107, E-ISSN 1891-8107, Vol. 8, no 1Article in journal (Refereed)
    Abstract [en]

    Records appraisal in the digital environment becomes a multi-professional enterprise, undertaken in the line of business, in which non-archivists play a vital role, but appraisal practices are not adjusted to this electronic reality. One aspect of this problem is the use and understanding of terminology. This paper presents a study on the usage of records-related terms in steering documents that affect records appraisal in Sweden. It uses a structured model for the analysis of steering documents. Used data sources are authoritative term databases and terminology report and steering documents from the three levels of regulations, i.e. Legislation and Regulations, Policy decisions and Instructions and Retention decisions steering documents from the Swedish National Archives and Stockholm City Archives, both archival authorities within their jurisdictions. The steering documents represents levels of hierarchical impact and are the foundations upon which appraisal is done and effectuated. Analysis of term frequency show change in vocabulary at level of hierarchy as well as development in time. Analysis of focus, characteristics and common features in definitions of terms show a variety of possible interpretations of the included terms, a result that affects appraisal and underpins a need for common corporate understanding in areas with multi-professional influences. The paper concludes that legal terms have impact on term use at regulation level, which lessens at lower levels, where vocabulary broadens. Difference is found between the two archival institutions studied, especially at decision level. Analysis of focus, characteristics and common features in definitions of terms show a variety of possible interpretations of the included terms, a result that affects appraisal and underpins a need for common corporate understanding in areas with multi-professional influences. An action suggested to mitigate risk is to form Communities of Practice for the task of records appraisal. One part of the task for these communities should be to agree upon shared concepts on used terminology that support electronic records appraisal. This would be a step where everyone involved develop a solid ground for the setting of the scope of appraisal. The idea of introducing Communities of Practice for the records and archives appraisal task is wider than the subject of this article, and should be further developed.

    Internet of Things: Pros and cons of CoAP protocol solution for small devices2016Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The growing number and integration of sensors and smart objects to the Internet is pushing the development of the Internet of Things (IoT) and with it the need for standardized applications protocols for the Web that is also suited to the constrained devices joining it. The IETF Constrained RESTful Environment (CoRE) working group has been working on the Constrained Application Protocol (CoAP) an application protocol that is aimed at machine-to-machine (M2M) communication. The main objective of this thesis is to evaluate this protocol solution for constrained nodes, observing its key features and functionalities and the way that those can improve the performance of nodes in IoT environments. The CoAP protocol will also be compared and analysed to other existing web protocols operating in similar conditions.

    Automated GUI regression tests via remote desktop with Robot Framework and Sikuli2014Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    To test software over a remote desktop is an increasingly common practice since outsourcing and offshoring of testing activities are on the rise. Most companies useproprietary testing tools which require an agent to be installed on the remote machine.This installation opens several attack surfaces and has thus the potential to compromise security. In addition license, support and other proprietary test tool costs might reduce the return on investment of automated tests to an unprofitable level, especially for relatively short projects.Robot Framework with Sikuli integration (RFSI) is a concept based on two open source tools which offer solutions concerning the security and cost issues. RFSI based tests do not need any further installations, access rights or network configurations on the remote machine, because of the fact that the tests are based on visual input. Therefore tests with RFSI cannot access the AUT (Application Under Test) or the remote machine in any other way than a manual tester could. Open-source tools, being freely available, also escape the problem of licence costs. The purpose of the proof of concept pilot study wasto give an answer on the question if RFSI can furthermore be considered an alternative to proprietary tools in terms of requirements for tool quality characteristics and for the external context of test automation projects.The methodology of this research followed the broader Goal-Question-Metrics method(GQM) described by Rini van Solingen and Egon Berghout, based on the GQM approachby Victor Basili and David Weiss. The requirements and metrics for the evaluation of RFSI in the study were selected through a literature study of ISO/IEC-TR9126-3 and other articles in the field. They comprehend six categories: functionality, reliability,maintainability and stability, efficiency, understandability and portability. For each category,metrics were established and adapted to the context of the proof of concept. The scope of the project was given by six use cases and test specifications, established in cooperation with system experts at the company CGI Sundsvall. These were then translated into RFSI test scripts and implemented with the requirements for successful remote GUI testing in mind.The results of the measurements for the proof of concept study showed that RFSI fulfilles the internal and external requirements for successful automated testing completely for functionality, understandability and portability. The requirements are partially satisfiedfor reliability, maintainability and stability, and efficiency.In conclusion, RFSI satisfies enough requirements to be considered a viable alternative to commercial testing tools for tests of GUI (Graphical User Interface) desktop applications over a remote desktop.

    On the Effect of Variations in paper composition on print quality2009In: International Conference on Digital Printing Technologies 2009, The Society for Imaging Science and Technology, 2009, p. 316-319Conference paper (Refereed)
    Abstract [en]

    During the last few years, digital printing technology has begun to play a significant role in the printing industry due to the quest for short runs and variable data printing. Digital printing using inkjet technology makes heavy demands on the paper's ability to rapidly absorb liquid and thereby increases the need to understand what parameters that affect the dynamics and interactions between paper and ink and how print quality is affected by these parameters. In this paper, the print quality for nine pilot papers with varying composition and eight different commercial papers has been studied. The printouts have been made with two small office/Home office printers; the print quality measurements for this study have been line quality-measurements and color -gamut volume measurements. The line quality and the color gamut volume for the commercial papers and the pilot papers are discussed.

    A study of AODV and DSR protocols: A meta-analysis of AODV and DSR protocols2016Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    There is a big number of people dying every year from car accidents and not solving this problem is a big issue. Communication protocols have been created in mobile ad-hoc network (MANET) to be able to solve this issue. AODV and DSR are two protocols that are used in this communication. The fact that there is mobile nodes makes it hard to keep track of the efficiency of this communication. This study has for objective giving a better understanding as to which protocol performs better and answering four important questions to know to be able to evaluate what protocol is better according to those parameters or criteria. The implemented method to solve this problem is through a meta-analysis and this meta-analysis is done through a qualitative research, literature review for critical literature reading and data collection to select the appropriate studies and exclud- ing the irrelevant studies based on other criteria. The evaluation of these param- eters are based on others’ work and reading the work from critical eyes. This study compares AODV and DSR from the criteria that are chosen. The study has a critical analysis of the results collected through the different papers show that AODV has outperformed DSR in most of the cases and answering the proposed questions in the study. Finally concluding that AODV is more effective in the case of high congestion compared to DSR but making a bit hard to have a clear cut answer when it comes to the criteria but AODV performed better in all the cases in high congestion.

    An experimental verification of single-frequency networks in multi-hop ad hoc networks2016Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    A multi-hop ad hoc network requires no infrastructure, like base stations or routers to function. This means that it can quickly be deployed and in movement, making it ideal for scenarios like natural disasters or battlefield communication. A single-frequency network (SFN) is the idea that transmitters can cooperate to send the same signals simultaneously over the same frequency channel, such that the signals are amplified. It was previously proposed that SFNs could be created in multi-hop ad hoc networks. According to simulations, this could improve the energy consumption, signal reachability, and data transfer rate. As this has only been simulated, the purpose of this project is to experimentally verify that SFN is attainable in a multi-hop ad hoc network, and to assess what the difficulties are of an actual implementation. The method involved synchronizing the transmission of two devices operating under the 802.11a standard. A multi-hop ad hoc network was created by changing the settings of the network interface cards. The devices used were mainly laptops and transmissions were monitored in Wireshark. The laptops were forced to send on one frequency channel to make interference possible, and identical packets were sent. Experiments were made to assess whether SFN was attained. The packet loss rate and distance were used to evaluate the results. The results suggest that a synchronized transmission off by less than 2 μs was attained. However, the error of these measurements were neither known nor approximable. This meant it was hard to know when a SFN was formed. The results indicate that SFN was attained, as the packet loss rate decreased significantly when employed. The effectiveness of SFN was hard to assess because the results were not comparable with the simulation values. The difficulty of an actual implementation is deemed to be the synchronization of transmissions.

    Utveckling och förnyelse av yrket arkivarie inom ABM-samarbetet i Västernorrland2013Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    In recent years it has become more and more common with discussions concerning professionalization in professions such as archivists. Professionalization means that a profession strengthens, develops, innovates and monopolize their business. In order to strengthen the profession you can also use a variety of strategies and these strategies emphasises the process where a profession is being professionalized or is about to be professionalized. This development of an occupation could start within ABM-cooperation’s. ABM stands for Archive, Library and Museum.

    The purpose of this paper is to examine how an ABM-cooperation has influenced and developed the institutions involved and their professions, job roles and tasks. As an example study to examine this I have chosen an ABM-cooperation in Västernorrland that consists of Riksarkivet Landsarkivet, Länsbiblioteket Västernorrland and Murberget Länsmuseet Västernorrland. To do this, I have contacted and sent questionnaires to employees in these three institutions. Three of these employees, I have also met in person to go over their answers. Prior to these meetings, I also conducted a literature review in which I have found out information about the background to the cooperation.

    The results show that none of the employees that I have interviewed think that their participation in the ABM-cooperation has led to major changes within their respective institutions. But when you read their answers to the questionnaires you can see that this is not the case. Duties have changed, been added, and the cooperation with the other institutions should be considered as a change in itself. One reason that these changes are not considered changes may be that cooperation has a long history and they have become part of everyday life in the workplace.

    There is no evidence in my results that an institution intentionally have used a strategy to develop and strengthen their workplace or professions though there are some points of contact. Instead, one can see signs that it has created a whole new strategy and a whole new approach to the co-operation started when the institutions and their employees in connection with the collaboration has strengthened their positions in their own institutions and with other participating institutions.

    Arkivteoretiska krav på informationen i molnet: En studie om vilka kunskaper som leverantörer av molntjänster har angående arkivteoretiska kvalitetskrav på information2013Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Idag pratas det mycket om ett fenomen som kallas Cloud Computing, vilket kan kort beskrivas som tillhandahållning av datorresurser så som informationslagring, processorkraft och applikationer via Internet. Begreppet Cloud Computing har ingen direkt motsvarighet på svenska men kan översättas till exempelvis molnbaserade datortjänster eller molntjänster. Vanligtvis så innebär Cloud Computing att it-företag hyr ut en del av en server samt annan datorservice till en organisation. Cloud Computing är ett attraktivt alternativ för både den privata och offentliga sektorn och efterfrågas i allt större utsträckning.

     

    Från ett arkivvetenskapligt perspektiv associeras Cloud Computing med många fördelar, men kanske med ännu fler nackdelar. De centrala problemföreställningarna relateras till tillit i en digital miljö. Frågor om hur information kan förbli autentisk, tillgänglig och fri från insyn från icke behöriga personer genom hela dess livscykel är framträdande i den arkivvetenskapliga debatten.

     

    Syftet med uppsatsen är att undersöka medvetenheten hos svenska leverantörer av molntjänster gällande de särskilda krav som ställs på arkivinformation, som kvalitetskraven pålitlighet, autenticitet samt tillgänglighet. Detta är något som inte har diskuterats i så stor utsträckning inom arkivvetenskapen.

     

    För att samla in det empiriska materialet genomfördes kvalitativa intervjuer med företag som på något sätt tillhandahåller molntjänster. Resultaten av intervjuerna analyserades med hjälp av teoretiskt material huvudsakligen baserat på The International Research on Permanent Authentic Records in Electronic Systems (InterPARES) forskning och begreppsbildningar.

     

    Resultat från studien visar att de tillfrågade företagen som tillhandahåller molntjänster arbetar mycket med säkerhet för att på så vis kunna så långt det är möjligt säkerställa att informationen förvarat i molnet förblir enligt vad de definierar som autentiskt och att kundens krav säkerställs. De har skilda uppfattningar om vad autenticitet innebär och vilket även delvis skiljer sig från den arkivteoretiska tolkningen. Tillgänglighet är ett av de främsta kraven som kunden ställer på informationen och som således är något som it-företagen prioriterar i deras tjänster.

    Castrix: Utveckling av webbsidan Sundsvall422012Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The goal of this Bachelor project was to develop the Sundsvall42 website,whose name originates from the conference held in week 42 and during whichall the IT-companies in Sundsvall gather and hold a number of different lectures.The website has been designed to accommodate both speakers and partipicants.All partipicants and lecturers will receive a personalized page inwhich there are a number of functions which are available for use, including ablog for each workshop and a calendar. The program used to create this isLiferay and the operating system is Linux. The entire website is encoded usingLiferay and Java, but the website is not adapted for use with the smaller screensize of the Smartphone. However, because of the Responsive Design technology,the website is able to adapt to various devices such as the Ipad and Smartphonesand the website will be able to adapt to the screen sizes of these devices.As it has all been processed using open-source, everyone has the right to accessthe source code. It is also possible for anyone to make changes to the code ifsuch changes are required. It is very important that two solutions are chosen asit is possible that one of the solutions will not prove to work adequately. Theconclusion was between the solutions given by both Liferay and HTML in ResponsiveDesign and it was determined that Liferay's version of ResponsiveDesign works better in its own environment.
