Age-related physical and cognitive changes hinder the ability of older adults to operate smartphones. While many user interface (UI) heuristics exist today, there is a need for an updated set designed specifically to assess the usability of mobile devices for an older audience. Smartphone evaluation heuristics for older adults based on age-related changes in vision, hearing, attention, memory and motor control were developed in this thesis by analyzing literature on age-related physical and cognitive changes impacting smartphone usability. Support for heuristics was found by gathering information on how older adults use cell phones through interviews and an online survey. It was demonstrated that strength of support for some heuristics increases with age. The evaluated heuristics provide usability practitioners and designers with a framework for evaluating the usability of smartphones for older adults.

Covid-19-viruset upptäcktes i Kina i slutet av 2019. Viruset spred sig snabbt och i mars 2020 klassades Covid-19 som en pandemi. Media har sedan dess rapporterat dagligen om utvecklingen av pandemin. Ett ämne som det även rapporterats om är det ökade naturintresset under pandemin. Flertalet naturområden har vittnat om ökat besöksantal, nedskräpning och slitage på naturen. Tidigare studier visar att slitage på naturen främst beror på bristande kunskap om allemansrätten. Syftet med uppsatsen är att undersöka om det finns samband mellan pandemin och det ökade naturintresset. För att undersöka detta spreds en digital enkätundersökning riktad till myndiga invånare i Kristianstad kommun. Enkäten innehöll frågor om invånarnas naturvanor både innan och under pandemin. Ett statistiskt test av resultatet bekräftade att myndiga invånare i Kristianstad kommun är ute oftare i naturen under pandemin än innan. Trettio procent av deltagarna svarade att deras naturvanor har förändrats under pandemin och flertalet menar att deras förändrade naturvanor lett till mer tid i naturen. Den vanligaste aktiviteten är promenad och den populäraste platsen för besök i naturen är sitt omedelbara närområde. För att undvika bestående skada på naturen av de förändrade naturvanorna kan ökad kunskap om allemansrätten vara en del av lösningen. / The Covid-19 virus was discovered in China in late 2019. The virus spread rapidly, and in March 2020, Covid-19 was classified as a pandemic. The media has since reported daily on the development of pandemic. One topic that also has been reported about is the increased interest in nature during the pandemic. Many nature areas have witnessed increased visitor numbers, littering, and wear on nature. Previous studies show that wear on nature is mainly due to a lack of knowledge about allemansrätten (the right of public access). The thesis aims to investigate whether there is a connection between the pandemic and the increased interest in nature.  A digital survey was distributed to adult residents in Kristianstad municipality to investigate this potential relationship. The survey included questions about the inhabitants' nature habits both before and during the pandemic. A statistical test of the result confirmed that adult residents of Kristianstad county are out in nature more often during the pandemic than before. Thirty percent of the participants answered that their nature habits have changed during the pandemic, and the majority believe that their changed nature habits have led to more time in nature. The most common activity is walking, and the most popular place to visit nature is its immediate local area. To avoid permanent damage to nature from the changed nature habits, increased knowledge of allemansrätten can be a part of the solution.

This research conceptualises IT infrastructure management at secondary schools in the WCED (Western Cape Education Department). This includes whether or not secondary schools in the WCED make use of a full time, on-site network administrator or whether a teacher acts as on-site network administrator. The literature review studied the effectiveness of IT infrastructure management which includes hardware, software, policies, computer network, security; staff management and BYOD (bring your own device). The management of IT infrastructure at secondary schools within the WCED differs widely from school to school, and its functionality depends on many factors. The quantitative study revealed problem areas within IT infrastructure management at secondary schools in the WCED. Furthermore the quantitative study also revealed that there is a need for best practice guidelines with regards to IT infrastructure management in order to improve service delivery. The literature review provided sources for best practice IT infrastructure management. / Rekenaar infrastruktuur by sekondere skole in die WKOD (Wes Kaapse Onderwys Departement) word in die navorsing beskryf. Die studie ondersoek verskillende strukture naamlike skole wat 'n voltydse netwerk administrateur het en skole waar 'n onderwyser die verantwoordelikheid aanneem van 'n netwerk administrateur. Die effektiewe beheer van rekenaar infrastrukture word bespreek. Dit sluit hardeware, sagteware, beleid formulasie, rekenaar netwerk, sekuriteit, personeel bestuur, en BYOD (bring jou eie toestel). Die bestuur van rekenaar infrastruktuur verskil van skool tot skool en die effektiewe bestuur daarvan word deur baie faktore beinvloed. Die kwantitatiewe studie het probleem areas vir die bestuur van rekenaar infrastruktuur by sekondere skole in die WKOD uitgewys. Die kwantitatiewe studie het verder die behoefte vir beste praktyk riglyne uitgewys om sodoende better dienslewering te verseker. Die literere studie het beste praktyk riglyne vir rekenaar infrastruktuur bestuur genoem. / Educational Leadership and Management
