Syfte Syftet med undersökningen var att kartlägga hur uthållighetsidrottare med fysisk funktionsnedsättning upplever sina möjligheter att utöva idrott jämfört med en grupp konventionella idrottare inom motsvarande uthållighetsgrenar. Metod En kvantitativ enkätundersökning med nio stycken påståenden och en öppen fråga tillämpades. Urvalet bestod av 40 stycken paraidrottare (medelålder = 31,5, SD = 12,1) i interventionsgruppen och 57 stycken konventionella idrottare (medelålder = 34,6, SD = 11,6) i kontrollgruppen. Resultat Paraidrottare upplevde signifikant sämre möjligheter än konventionella idrottare gällande träningsgrupp i närheten (p = 0,002), känsla av tillhörighet (p = 0,001) och tillgång till utrustning (p = 0,009). Det totala medelvärdet på påståendena enligt likerskalan i enkäten var 3,76 (SD = 1,23) för paraidrottare och 3,97 (SD = 1,02) för konventionella idrottare. Slutsats Att paraidrottare både upplever avsaknad av träningsgrupp i närheten och lägre tillhörighetskänsla kan möjligen hänga ihop, dvs. att svårigheterna att få träningssällskap sänker tillhörighetskänslan. För framtida forskning efterfrågas en kvalitativ undersökning med ledare inom paraidrott för att öka förståelsen för träningsmiljö och tillgången till utrustning. / Aim The aim of the survey was to chart how endurance athletes with physical disabilities experience their opportunities to exercise sport compared to a group of conventional athletes within endurance sport. Method A quantitative survey with nine statements and an open question was applied. The sample consisted of 40 athletes with physical disability (mean age = 31.5, SD = 12.1) in the intervention group and 57 conventional athletes (mean age = 34.6, SD = 11.6) in the control group. Result The athletes with physical disabilities experienced significantly worse opportunities than conventional athletes regarding training group nearby (p = 0.002), sense of belonging (p = 0.001) and access to equipment (p = 0.009). The overall mean of the claims with likert scale in the survey was 3.76 (SD = 1.23) for athletes with physical disabilities and 3.97 (SD = 1.02) for conventional athletes. Conclusion Athletes with physical disabilities both experience the absence of a training group nearby and a lower sense of belonging may be possible, ie. the difficulty in getting a training company reduces sense of beloning. For future research, a qualitative survey with leaders in disability sports is required to increase understanding of the training environment and access to equipment.

This paper explores how influencers can be categorised using a self-administered questionnaire. In doing so, the study can contribute to an understanding of the phenomenon that is more extensive than what previous research has attributed. The focus of this paper is on how influencers can be better understood for the benefit of public relations (PR), marketing, and communication. The purpose of this project is to investigate whether the term influencers (short for social media influencers) are defined by scholars in a similar fashion to how the study sample categorises influencers. Thus, the research question of the study is to examine if the study sample finds the term influencer applicable to the five suggested categories that are stated in the survey. The results from this study show that scholars commonly confine the phenomenon of influencers to bloggers, vloggers, and instagrammers. However, the results from the survey indicate that the study sample has a broader perception of the phenomenon. According to the participants, all suggested categories are fitting the term influencer, namely: blogger/vlogger/instagrammer, celebrity, athlete, entrepreneur, politician. Although the latter, politician, is deemed the least fitting category. Thus, the findings in the study show that there is a discrepancy between the public perception of how to define influencers and previous research in the field. This implicates that public relation practitioners need to rethink how they perceive and apply influencer marketing. Using influencers for marketing purposes requires organisations to execute a thorough selection process to ensure a suitable partnership.

In the late 1990s and early 2000s several revenue recognition scandals arose, which led to a discussion about the need for a new principle-based standard with a balance sheet-based approach for revenue recognition. On 1st of January 2018 IFRS 15 Revenue from Contracts with Customers became effective and replaced all previous revenue recognition standards and interpretations. All companies are expected to be affected regarding when and how much the company reports its revenue, though the scope may vary from one company to another. This study aims to investigate how the application of IFRS 15 has impacted companies based on the business models they apply in their customer agreements. To operationalize the purpose of the study a quantitative method was adopted to gather the empirical data, which have been obtained from the companies’ annual reports. An enumeration was implemented, why all listed companies on Nasdaq Stockholm which are required to implement IFRS 15 have been studied. The results indicate that a minority of the companies have showed an impact and most of the companies have not been impacted after an implementation of the new revenue recognition standard. The study has identified that the reason why companies are affected by IFRS 15 depends on the business models’ companies apply in their customer agreements. The minority of companies that have been affected by IFRS 15 are the ones which have developed business models that includes complex customer contracts, i.e. customer contracts consisting of complex commitments and promises of goods and services to customers. Accordingly, the majority of the studied companies uses business models with non-complex customer contracts in their customer agreements, e.g. simple sale of only one good, hence their revenue recognition under IFRS 15 does not differ from previous accounting standards.

[pt] A mobilidade em médias e grandes cidades brasileiras como o Rio de Janeiro tem se caracterizado pela utilização ineficiente do espaço público, juntamente com a redução da utilização do transporte coletivo. Qualquer mudança nas rotas e frequências de linhas no transporte coletivo assim como o surgimento de novas tecnologias e variação das tarifas geram efeitos sobre a distribuição de fluxos de passageiros. Juntando-se a esse contexto, há a atual conjuntura econômica do Rio de Janeiro onde acaba não sobrando recursos para investir em estudos e na implementação de melhoria da mobilidade urbana da cidade. Este trabalho apresenta uma análise de alternativas de cenários focados no metrô e em conexões do BRT com trens por já terem uma infraestrutura pré-existente o que facilitaria a construção dessas obras. Esta pesquisa mostra como as obras incluídas nos cenários propostos para 2016 e 2021 no Plano Diretor de Transportes do Rio de Janeiro estão discrepantes com a rede de transporte no ano de 2019 e por consequência o fluxo de passageiros na rede é diferente do previsto. Com o auxílio do software EMME e utilizando uma rede de transporte simplificada e mais atualizada da Região Metropolitana do Rio de Janeiro, foi realizada a alocação do transporte coletivo baseado no modelo de estratégias ótimas de Spiess (1983), contido no EMME. Dessa forma verificou-se como a construção dessas novas infraestruturas de transporte alteraria o fluxo de passageiros. A partir desses resultados pode-se concluir que investir em conexões entre os modos e em obras que sejam capazes de retirar uma quantidade significativa de veículos da rede é um caminho chave para a Região Metropolitana já que esses investimentos deixam a rede de transporte menos congestionada e melhoram a qualidade de vida da população, além de seguir a apelo pelo desenvolvimento mais sustentável dos sistemas de transportes. / [en] Mobility in medium and large Brazilian cities such as Rio de Janeiro has been characterized by the inefficient use of public space, together with the reduction in the use of public transport. Any change in routes and line frequencies in public transport, as well as the emergence of new technologies and variation of fares, have an effect on the distribution of passenger flows. Adding to this context, there is the current economic situation in Rio de Janeiro, where there are no resources left to invest in studies and in the implementation of improving the city s urban mobility. This work presents an analysis of alternative scenarios focused on the trains and on BRT connections, as they already have a pre-existing infrastructure, which would facilitate the construction of these works. This research shows how the works included in the scenarios proposed for 2016 and 2021 in the Rio de Janeiro Transport Master Plan are discrepant with the transport network in 2019 and, consequently, the flow of passengers on the network is different from the forecast. With the aid of the EMME software and using a simplified and more up-to-date transportation network in the Metropolitan Region of Rio de Janeiro, public transportation was allocated based on the optimal strategies model of Spiess (1983), contained in the EMME. Thus, it was verified how the construction of these new transport infrastructures would alter the flow of passengers. From these results, it can be concluded that investing in connections between modes and in works that are capable of removing a significant number of vehicles from the network is a key path for the metropolitan region as these investments make the transportation network less congested and improve the population s quality of life, in addition to following the call for more sustainable development of transport systems.

Detta examensarbete syftar till att svara på ett av Trafikverket fastställt problem: en gemensam regional cykelplanerings process skulle göra dem billigare och mer jämförbara. De erbjuder för närvarande planerarna en modell som utvecklades av Kågeson 2007. Denna modell har formen av en rapport som ger råd om när man ska bygga en cykelväg mellan städer eller platser i en region. Ändå används den bara i endast 6 av de 21 svenska länen. Trafikverket kräver ett nytt planeringsstödverktyg, mer interaktivt och komplett än Kågeson-modellen. Några nya önskade funktioner är separationen av efterfrågan per syfte, införandet av e-cyklar, olika resesyfte och en prioritering av investeringarna.  Examensarbetet är att designa och implementera det här verktyget, även kallat Planning Support System (PSS), som syftar till att jämföra utbud och efterfrågan på cykelväg till prioritering av infrastrukturförbättringar. En huvudbegränsning för modellen är att den måste vara billig datavis, men så komplett och exakt som möjligt. Det baseras på flera öppna dataleverantörer, till exempel OpenStreetMap, den svenska nationella vägdatabasen (NVDB) eller reseundersökningar från Sverige och Nederländerna. Resultatet är en modell, uppdelad efter turändamål och typ av cykel.  Del för efterfrågeuppskattning anpassar en klassisk fyrsteg transportmodell till cykelplanering och begränsad data. För olika resändamål genereras och distribueras resor tack vare en ursprungs begränsad gravitationsmodell. Valet av cykelläge är anpassat till det faktiska resebeteendet genom logistisk regression med en binär logit-modell. Resorna tilldelas sedan nätverket med tilldelnings metoden "allt-eller-ingenting" genom Dijkstras algoritm. För att utvärdera cykelförsörjningen använde vi ett mått som heter Level of Traffic Stress (LTS), som uppskattar den potentiella användningen av en nätverkslänk för olika delar av befolkningen som en funktion av vägnätvariablerna. Prioriteringsrankningen är då förhållandet mellan mått på efterfrågan och utbud.  Detta nya verktyg implementeras med opensource Geographic Information System (GIS) som heter QGIS och med Python 3 och testas i Södermanlands län / This Master Thesis main objective is to answer a problem set by the Swedish Transport Administration: a common regional bicycle planning process would them cheaper and more comparable. They currently offer the planners a model developed by Kågeson in 2007. This model takes the form of a report which advises on when to build a bicycle path between cities or places of a region. Still, it is only used in only 6 of the 21 Swedish counties. Trafikverket requires a new planning support tool, more interactive and complete than the Kågeson model. Some new desired features are the separation of demand per purpose, the inclusion of e-bikes, different trip purposes, and a prioritization of the investments.  The Degree Project work is to design and implement this tool, also called Planning Support System (PSS), which compares supply and demand for bicycle path to prioritizing infrastructure improvements. A main constraint for the model is that it needs to be cheap data-wise, but as complete and precise as possible. It bases on several open data providers, such as OpenStreetMap, the Swedish National Road Database (NVDB), or Travel Surveys from Sweden and the Netherlands. The result is a model, disaggregated by trip purpose and type of bicycle.  The demand estimation part adapts a classic four-step transportation model to bicycle planning and limited data. For different trip purposes, trips are generated and distributed thanks to an origin-constrained gravity model. Bicycle mode choice is fit to actual travel behaviour through logistic regression with a binary logit model. The trips are then assigned to the network using the "all-or-nothing" assignment method through the Dijkstra algorithm. To evaluate bicycle supply, we used a metric called Level of Traffic Stress (LTS), which estimates the potential use of a network link by different parts of the population as a function of the road network variables. The prioritization ranking is then the ratio between demand and supply metrics.  This new tool is implemented with the opensource Geographic Information System (GIS) called QGIS and with Python 3, and it is tested on Södermanland County.

Background: Revenue recognition has been a debated issue for a long time. During the 1990s and 2000s, several critical revenue related events took place. These events led to the development of a new standard for revenues called IFRS 15"Revenue from contracts with customers". One year has passed since the adoption in Swedish law and the aftermaths are available for analysis. The implementation of IFRS 15 is expected to affect the revenue reporting and the disclosure requirements referred to them. However, this change is not expected to affect all industries the same way but will likely depend on business model used. Purpose: The purpose of the study is to illustrate how revenue recognition has been affected by the implementation of IFRS 15 from an industry perspective as well as increase understanding of why some industries are affected and others not. Method:IFRS 15 has one single model for all revenuearising from contracts with customers and the standard also includes expanded disclosure requirements. The first approach examines how net sales change in companies when implementing IFRS 15. The reason for this is to determine if the standard has had anyeffect on the company's sales revenue. The second approach in the study is to examine the companies segment reporting to determine whether the implementation have had an effect on the company's financial report, based on the expanded disclosure requirements. Some industries are expected to be affected more than others which is why both approaches are examined from an industry-oriented perspective. Results: Customer serviceand telecom are the two industries that have the most affected net sales in connection with the implementation of IFRS 15. The two industries that showed the biggest impact on changed segment reporting are industrial and health care. Oil and gas and utilities reported no impact on net sales or changed segment reporting.

Two different focus groups in primary schools in Uganda participated in this study to investigate critical aspects of usability comparing two different educational mobile applications. The first group was already familiar with both applications, while the second group had no previous experiences of the applications. Furthermore, interviews were performed with a head teacher as well as two CEOs and founders of two start ups developing educational mobile applications for children, in order to investigate challenges with implementation of mobile learning in schools in Uganda. The results showed that one of the applications was not fully compatible with the devices used by the target group and that swiping was perceived less natural than clicking. Regarding organizational factors of implementation in schools, financial limitations and insufficient computer literacy among employees were revealed as critical obstacles. Moreover, improvements of the method used during the user tests with children in foreign contexts are discussed. / I denna studie deltog två fokusgrupper med barn från två olika grundskolor i Uganda för att undersöka kritiska aspekter gällande användarvänlighet genom att jämföra två mobilapplikationer som används i utbildningssammanhang. Den första gruppen var redan bekant med båda applikationerna, medan den andra gruppen var obekant med applikationerna. Vidare undersöktes utmaningar med implementation av mobile learning i grundskolor i Uganda genom intervjuer med en rektor från en ugandiansk grundskola samt två VDs tillika grundare från två ugandianska edTech-start-ups. Resultaten visade att en av applikationerna inte var fullständigt kompatibel med de enheter som användes av målgruppen i Uganda samt att "swipea" uppfattades mindre naturligt än att klicka. Gällande organisatoriska faktorer av implementering i skolorna visades finansiella begränsningar och anställdas otillräckliga datakunskap vara kritiska hinder. Utöver resultaten som ämnar svara på de definierade frågeställningarna diskuteras förbättringar av metoden som användes för användartesterna, i syfte att ge riktlinjer till framtida projekt i liknande sammanhang.

Hos Coca‐Cola European Partners är efterfrågan hög på varierande produkter, vilket göratt flödet består av flera omställningar från att producera en viss produkt till en annan.För att säkerhetsställa att produktionseffektiviteten är hög, bör tiden på momenten somej är värdeadderande minimeras. Genom ställtidsreducering ökar maskinensutnyttjandegrad samt vid standardisering underlättas planeringsarbetet förproduktionsteamet. Som en ideologi användes LEAN‐filosofin som bygger på att maximera kundnyttan ochminimera slöserier genom effektivisering. För att eliminera moment som inte har någotvärde för kunden utnyttjades metoder som SMED, 5S och PDCA. SMED‐metodenanvändes på ett strukturerat arbetssätt för att hantera inre och yttre ställtider vilket skaeffektivisera produktionsprocessen. Dessutom användes förbättringsverktyget Ishikawa(orsak‐verkan‐diagram) för att åskådliggöra rotorsaker till det definierade problemet. Målet med examensarbetet var att identifiera förbättringsförslag för att reduceraproduktionens ställtider. För att grunda förbättringsförslagen utfördes observationer föratt begripa hur processen fungerar, och för en detaljerad förståelse utfördes intervjuermed relevant personal. Litteraturstudie genomfördes för att utvidgaproduktionskunskaper för att lättare kunna spåna idéer vilket i sin tur berikaderesultatet. Examensarbetet har resulterat i att införa ett kommunikationshjälpmedel för atteffektivisera kommunikationen mellan samtliga stationer. För att reducera operatörersbegripsvårigheter medfördes förbättringsförslaget att införa mer visuella manualhanböcker för maskiner. Vid rengöringsprocessen föreslogs införing av envalfunktion i styr‐ och reglersystemet, där tekniker har möjligheten att behandla berördarör från tidigare produktionskörning. Förbättringsförslagen estimeras spara företaget uppemot 1 040 000 kr årligen. / At Coca‐Cola European Partners, demand is high for varying products, which means that the flow consists of several switches from producing a particular product to another. To ensure that production efficiency is high, the time on moments that are not value‐editing should be minimized. With stand‐by reductions, the utilization rate of the machine increases, and in the case of standardization, the planning work for the production team is facilitated. As an ideology, the LEAN philosophy was used, based on maximizing customer benefits and minimizing waste through efficiency. To eliminate points that have no value for the customer, methods such as SMED, 5S and PDCA were used. The SMED method was used in a structured way of working to handle internal and external set times, which will streamline the production process. In addition, the Ishikawa enhancement tool (causeeffectdiagram) was used to illustrate rotor causes to the defined problem. The aim of the thesis was to identify improvement proposals to reduce production deadlines. In order to base the improvement proposals, observations were made to understand how the process works, and for a detailed understanding interviews were performed with relevant personnel. Literature study was conducted to expand production skills in order to more easily predicted ideas, which in turn enriched the results. The thesis work has resulted in the introduction of a communication aid to streamline communication between all stations. In order to reduce operator comprehension difficulties, the proposed improvement was introduced to introduce more visual manual manuals for machines. In the cleaning process, it was proposed to introduce a selection function in the control system, where technicians have the ability to process affected pipes from previous production run. The improvement proposals are estimated to save the company up to SEK 1,040,000annually.
