Äldres digitala utanförskap i Sverige

Lobell, Martin, Tiwe, Anton January 2020 (has links)
Denna uppsats berör det rådande digitala utanförskap som många äldre svenskar i åldrarna 66+ idag upplever. Fokus har riktats mot anledningarna till vad utanförskapet beror på och vilka eventuella lösningar mot detta som går att ta fram. Studieprocessen är av slaget Design and Creation och består av både kvantitativa och kvalitativa data. Förutom att utföra litteraturstudier har datainsamlingar uträttats genom analys av stora datasets, enkätundersökningar och andra metoder som Customer Journey Mapping.Den främsta anledningen till att denna studie utförts är att det blir allt mer fundamentalt att ta del av de nya, digitala alternativ till de samhällstjänster som svenskarna behöver tillgång till jämt. Därmed innebär det att om man själv inte är villig eller inte har möjlighet att delta i övergången från analogt till digitalt så riskerar man att uppleva konsekvenser av detta på flera olika plan, inte minst ekonomiska.Forskningsfrågan som studien avser besvara är “Hur kan man bistå de äldre i digitalt utanförskap för att motivera dem till att börja använda internet?” och har sedermera brutits ner till fyra underfrågor för att lättare angripa de olika problemområden som ligger till grund för problematiken bakom den stora forskningsfrågan.Studien kastar ljus på heuristiska riktlinjer och principer som kan användas för att designa och utveckla mjukvara särskilt anpassad för äldre såväl som kvantitativa data som visar användningsstatistik m.m.Några viktiga slutledningar som går att dra från denna studie är vikten av att utvecklare börjar ta äldre människor i större beaktande när de utvecklar. Vidare har det tydligt framgått att de äldre som antingen inte vill eller känner att de kan använda internet och annan mjukvara kan och bör motiveras att övervinna sina farhågor. Detta görs bäst genom övning med hjälp av instruktioner. / This essay addresses the prevailing digital exclusion that many older Swedes aged 66+ are experiencing today. The focus has been on the reasons for what the exclusion is due to and what possible solutions to this can be developed. The study process is of the design and creation type and consists of both quantitative and qualitative data. In addition to conducting literature studies, data collections has been conducted through analysis of large datasets, survey surveys and other methods such as Customer Journey Mapping.The main reason why this study was carried out is that it is becoming increasingly fundamental to take advantage of the new, digital alternatives to the community services that the Swedes need access to constantly. This means that if you yourself are not willing or do not have the possibility to participate in the transition from analog to digital, you risk experiencing the consequences of this on several different levels, not least financial ones.The research question that the study aims to answer is "How can we assist the elderly in digital exclusion to motivate them to start using the internet?" and has subsequently been broken down to four sub-questions to more easily address the various problem areas that underlie the major research issue.The study sheds light on heuristic guidelines and principles that can be used to design and develop software specially adapted for older as well as quantitative data showing usage statistics etc.Some important conclusions that can be drawn from this study are the importance of developers starting to take older people into consideration when developing. Furthermore, it has become clear that the elderly who either do not want or feel that they can use the internet and other software can and should be motivated to overcome their fears. This is best done through practice with the help of instructions.

Learning and Application of Range Management Innovations Among Ranchers in West-Central Colorado

Kennedy, Caroline A. 01 May 2005 (has links)
Like many ranchers in the West, ranchers in West-Central Colorado are reevaluating their management strategies in the face of forces like drought, rising land prices, and encroaching development. While ranchers seek answers on alternative management strategies, research and Extension personnel search for adequate means of diffusing needed information. Relative to many rural western communities, ranchers in West-Central Colorado show high interest in alternative range management ideas, and many implement changes to their ranch management based on these ideas. This can partially be attributed to a unique support system of Extension and agency personnel with effective, untraditional outreach and land-management approaches. A survey was mailed to all 647 persons on the mailing list for the CSU Tri-River Extension Office, including Forest Service and BLM permittees in Mesa, Delta Montrose, San Miguel, Ouray, Hinsdale, Saguache, and Gunnison counties. The survey was designed to gain insight on how ranchers perceive current Extension efforts, how they learn new management information from peers and Extension/agency personnel, and how they apply these new ideas to their operations. Subsequent qualitative interviews with respondents gathered information on the process of adapting and implementing range management innovations into individual operations. This paper presents the findings of the survey and interviews, and implications for future outreach efforts.

Interpretation and Application of Elements of Differential Geometry and Lie Theory

Brannan, James R. 01 May 1976 (has links)
Basic concepts of differential geometry and Lie theory are introduced. Lie transformation groups are applied to linear systems of differential equations and the problem of describing rigid body orientation. Linear Hamiltonian systems are then treated as a Lie system of differential equations. This theory is applied to a particular Hamiltonian system arising from a problem in control theory, the linear state regulator problem.

Auxin Herbicide Effects on Glyphosate Efficacy and Cotton (Gossypium Hirsutum) Yield

Smith, Chad Lee 12 August 2016 (has links)
Field, greenhouse and laboratory experiments were implemented to investigate the effects of auxin herbicides on growth and yield of cotton in glyphosate based systems. Field experiments evaluated the effect of rate and timing of dicamba or 2,4-D exposure when applied in glyphosate-resistant cotton. Increasing rates of either dicamba or 2,4-D resulted in increased injury and yield reductions. Initial injury symptomology was similar for cotton exposed at vegetative and reproductive stages. When cotton was exposed to auxin herbicides during vegetative growth, injury increased with time, while foliar injury during reproductive growth was stagnant and often decreased with time. Subsequently, the strongest correlations to yield loss and injury were from later evaluations of vegetative timings. Recovery from injury due to auxin herbicide exposure was dependent upon favorable environmental conditions; however, recovery was often superficial and masked significant yield loss. Greenhouse studies evaluated the impact of the diglycolamine dicamba salt on the movement of 14C radio-labeled potassium salt glyphosate in barnyardgrass and johnsongrass. Increasing glyphosate rate increased total absorption of glyphosate in both species. Total absorption of glyphosate was not impacted by the presence of dicamba, for either johnsongrass or barnyardgrass. Dicamba did not consistently alter the translocation of glyphosate in johnsongrass; however, dicamba did reduce glyphosate translocation in barnyardgrass. Total amount of translocated glyphosate was 2.6 to 4.6% and 3.8 to 6.8% of applied in barnyardgrass and johnsongrass, respectively. Reduced translocation in barnyardgrass was a result of increased glyphosate accumulation in the distal portion of the treated leaf. Increasing the rate of glyphosate did overcome the dicamba induced antagonism; however, altered translocation of glyphosate has been documented to be a precursor to herbicide resistance.

本論文はブロックチェーン技術を用いた,貧弱な情報通信(ICT)環境下での高信頼なデータ管理システムの設計と実装について述べたものである.住民データ管理システムの構築において最も重要な点の一つが,データの信頼性である.データを電子化して記録するときには,特にデータの改ざんが大きな課題になる.従ってデータの改ざんが起こらないこと,少なくとも改ざんされたことを検知することが必須となる.そこで着目したのがブロックチェーン技術である.ブロックチェーンの本質は,改ざんが原理的には不可能ではないが実質的には極めて困難な追記型データベース技術である.そこでその特性を利用して,信頼性の高い住民情報管理用のデータベースを構築できると考えた. / This study investigates the design and implementation of data management system with high level reliability and security by blockchain technology. The data access environment provided by blockchain is highly secure and trustworthy. In blockchain system, some data fragments are grouped into one piece called as blocks, and all blocks are connected to create a chain of blocks in database. When blocks are connected, hash value is used to connect blocks properly. Blockchain technology enables highly secure and reliable data management system under relatively poor ICT environment. For example, developing countries such as African countries do not have sufficient ICT environment. Therefore adopting blockchain technology is suitable for such countries. Based on this consideration, we started to build data management system on the blockchain system. / 博士(工学) / Doctor of Philosophy in Engineering / 同志社大学 / Doshisha University

Nanocomposite High Displacement Strain Gauges for use in Human-Machine Interfaces: Applications in Hand Pose Determination

Calkins, Thomas B. 18 April 2011 (has links) (PDF)
Conductive nanocomposites are finding many uses as multi-functional materials. One recent development involves the creation of high displacement strain gauges, which have potential applications in a variety of engineering roles. The piezoresistive nature of the gauges makes possible their strain sensing capability. The intent of this research is to show that specific High Displacement Strain Gauges can successfully be used in one human-machine interface application that will demonstrate their potential for a range of other human-machine interface applications. This will be shown in the development of these sensors to accomplish hand pose determination. The flexible and inexpensive gauges are attached to several locations on a glove. It is then shown that by linking this glove with software, the position of the hand can be interpreted into the letters of the American Sign Language alphabet. This use of this nanocomposite sensor establishes the potential for future applications. Issues such as accuracy of response, cyclability, recalibration and reliability are discussed. A design of experiments is accomplished in order to evaluate the effects of modification of the gauges in order to overcome these issues. This work develops the potential of these sensors for use in human-machine interface applications such as computer games, remote controls, robotics, prosthetics and virtual reality applications.
