The importance of increasing renewable energy production to facilitate a sustainable energy transition has been well-discussed and reinforced worldwide. In land- and resource-scarce and tropical Singapore, solar has been deemed the most feasible renewable energy technology for the country moving forward. Previous studies have focused on assessing the feasibility of various solar technologies. This paper instead analyses the rooftop solar power production potential of existing high-rise residential buildings in Singapore, and thus contributes to reaching the national solar goal using geographic information system geospatial imagery.  For this study, the chosen focus area is the south of Jurong East in Singapore. Results show that solar deployment on all available public high-rise residential building rooftop areas in the focus area will be able to generate a total potential solar peak power and annual solar energy output of 2-megawatt peak and 2.8-gigawatt hour per year respectively. This equates to meeting the energy demand of 679 public residential apartments in the focus area and meeting 0.18% of the national solar goal of reaching 1.5- gigawatt peak by 2025. In an urban context, the use of geospatial analysis has been presented to benefit urban planning especially with regards to the integration of rooftop solar photovoltaic systems.

En utgångspunkt för denna studie har varit att flera svenska elever har svårigheter att lösa matematiska textuppgifter. I ett försök att utveckla elevers förmågor att lösa matematiska textuppgifter har Singaporemetoden blivit allt mer populär. I Singaporemetoden används blockmodellen för att visualisera textuppgifter. Syftet med följande uppsats är att, utifrån ett sociokulturellt perspektiv, synliggöra hur fem lärare uppfattar att blockmodellen kan stötta elever i att utveckla problemlösningsförmågan när de löser textuppgifter. Uppsatsen syftar även till att synliggöra vilka erfarenheter lärarna har av att arbeta med blockmodellen i matematikundervisningen för årskurserna 1–6. Studien utgår från en kvalitativ metod där syftet besvaras genom fem enskilda semistrukturerade intervjuer med grundlärare som undervisar utifrån blockmodellen i matematikämnet. Studien har utgångspunkt i Vygotskijs sociokulturella teori och har inspirerats av en tematisk metodanalys. Resultatet visar att lärare uppfattar att det finns såväl fördelar som nackdelar med att använda blockmodellen i matematikundervisningen. Lärarna uppfattar att blockmodellen främst är stöttande genom att modellen strukturerar textuppgifter och stödjer elever och lärare att ta sig an textuppgifter. Med stöd av blockmodellen visualiseras dessutom matematiska områden och elever ges möjlighet att utveckla matematisk förståelse. Modellen kan även hjälpa lärare att skapa samtalssituationer för att låta elever utvecklas i den proximala utvecklingszonen. I samtalen får elever möjlighet att utveckla problemlösnings-, begrepps-, resonemangs- och kommunikationsförmåga. Resultatet visar även att främsta utmaningen är att modellen innehåller många steg som kräver att rita och skriva vilket inte passar för alla elever. Blockmodellen ger dessutom upphov till utmaningar när det gäller att differentiera undervisningen, eftersom arbetet oftast sker gemensamt med uppgifter på en specifik svårighetsgrad. Slutsatsen är att blockmodellen kan stötta elever i att utveckla problemlösningsförmågan i textuppgifter i kombination med lärarens kompetens. / The premise for this study has been that swedish upper primary- and lower secondary pupils have been shown to have difficulties in solving textual tasks in mathematics. In an attempt to develop pupils’ abilities in solving these textual tasks, the Singapore model has become increasingly popular. The Singapore model utilizes what is known as the bar model, which is used to visualize the text within these tasks. The purpose of this study is to highlight how five teachers perceive that the bar model can support pupils in developing problem-solving skills in textual tasks, from a socio-cultural perspective. The study also aims to highlight the experiences the teachers have gained from working with the bar model in mathematics teaching for grades 1-6. The study's purpose has been answered through five individual, qualitative and semi-structured interviews, with primary teachers who teach mathematics with the support of the the bar model. The study uses Vygotskij’s sociocultural theory and has been further inspired by a thematic method analysis to present and understand the results. The results show that teachers perceive both advantages and disadvantages in using the bar model in mathematics teaching. The teachers expressed that the bar model is primarily supportive in that the model structures textual tasks and supports pupils and teachers when approaching textual tasks. With the support of the bar model, abstract areas are also visualized and the pupils gain an increased mathematical understanding. The model can also contribute to creating conversational situations in order for pupils to develop in regards to the proximal development zone. In these conversations, pupils are given the opportunity to develop problem-solving, conceptual, reasoning and communicational skills. The results also show that the main challenge is that the model contains many elements that require drawing and writing, which are not suitable for all pupils. The bar model also gives rise to challenges in regard to differentiating the teaching, since the work usually takes place jointly with tasks at a specific degree of difficulty. The conclusion is that the bar model can support pupils in developing problem-solving skills in textual tasks in combination with teacher competence.

Denna uppsatts behandlar matematikundervisning i Estland och Singapore. De två länderna har över tid presterat högt och bra i PISA-undersökningar och det är därav intressant att se vad som kan vara faktorer till denna framgång utifrån ett undervisningsperspektiv. Syftet med studien är sammanställa kännetecken och faktorer som berör matematikundervisning i Estland och Singapore. Genomförandet av systematiskt sökande i databaser genererade tolv vetenskapliga texter som analyserades och blev underlaget för att kunna identifiera kännetecken och faktorer som berör matematikundervisning i länderna. Resultatet visar att Singapores matematikundervisning kännetecknas av problemlösning samt att läraren och läroböcker är faktorer som tycks vara signifikanta. Estlands matematikundervisning kännetecknas av ambitionen att lära för livet och faktorer som att lärare och skolors frihet att anpassa läroplan och undervisningen, framstår som väsentlig. Studien konstaterar att det inte finns en sanning till framgångsrikt lärande då länderna påvisar betydande skillnader. Således identifieras det också likheter och det konstateras att problemlösning kan vara en framgångsfaktor för god matematikundervisning.

This study identifies additional investment incentives, applicable to the manufacturing sector, which the South African government could introduce to encourage investors to choose the South African manufacturing sector as a desired investment destination. A comparison is made between the relevant investment incentives provided to manufacturing companies by Malaysia and Singapore and those provided by South Africa, in order to examine the similarities and differences between these incentives. In the light of these findings, recommendations are made for revised or additional investment incentives in South Africa to promote investment in South African manufacturing companies and reduce some of the barriers that prevent local and foreign investment in South Africa. / Accounting / M.

In this thesis the position of parties under a fixed-term agreement under section 14 of the Consumer Protection Act 68 of 2008 is analysed critically. The purpose of this thesis is first to establish whether parties to a fixed-term agreement are better protected in terms of section 14 of the CPA when the consumer needs to terminate the contract based on the material failure to perform by the supplier, than under the common law. Second, this thesis explores whether the maximum duration of fixed-term agreements should be limited by statute. Various aspects affecting parties to these agreements, for instance the freedom to contract, pacta servanda sunt, and standard-form agreements, are considered. The South African position is then compared to the position in Singapore under the Consumer Protection (Fair Trading) Act, and to the United Kingdom under the Consumer Rights Act, to gain perspective and objectively evaluate the provisions of section 14 of the Consumer Protection Act 68 of 2008 to establish whether South Africa can benefit from lessons learnt from these jurisdictions. Finally, principle-based amendments to the provisions of the CPA are recommended to improve the position of the consumer under fixed-term agreements to effect best practice solutions and ensure adherence to the aims and purposes of the Consumer Protection Act 68 of 2008 and international guidelines. This thesis is based on the law as at 18 June 2020, found in sources available in South Africa, and Singaporean law available in the database of the National University of Singapore. / Hierdie proefskrif is ’n kritiese analise van die posisie van partye tot vastetermynkontrakte ingevolge artikel 14 van die Suid-Afrikaanse verbruikersbeskermingswetgewing, die Consumer Protection Act 68 van 2008 (CPA). Die doel van die analise is eerstens om vas te stel of partye tot ’n vastetermynkontrak ingevolge artikel 14 van die CPA beter beskerming geniet ingevolge die CPA wanneer die verbruiker die vastetermynkontrak moet beëindig weens die wesenlike wanprestasie deur die verskaffer, as ingevolge die gemenereg. Tweedens ondersoek die proefskrif of dit wenslik is dat die maksimum duur van vastetermynkontrakte deur wetgewing beperk word. Verskeie aspekte wat die posisie van partye tot vastetermynkontrakte beïnvloed word ondersoek, onder andere kontrakteervryheid, die leerstuk pacta servanda sunt en standaardkontrakte. Die Suid-Afrikaanse posisie word dan vergelyk met dié in Singapoer, ingevolge die Consumer Protection (Fair Trading) Act (CPFTA), en die Verenigde Koninkryk, ingevolge die Consumer Rights Act (CRA) om perspektief te kry op die studie, en ten einde die bepalings van artikel 14 objektief te oorweeg om vas te stel of Suid-Afrika kan kersopsteek by hierdie jurisdiksies. Laastens word voorstelle gemaak om die posisie van die verbruiker tot vastetermynkontrakte ingevolge die CPA te verbeter om beste gebruikspraktyke te implementeer, en te verseker dat die doelwitte van die CPA en internasionale verbruikersriglyne bereik word. Hierdie studie weerspieël die regsposisie soos op 18 Junie 2020 in bronne wat plaaslik beskikbaar is, asook in bronne aan my beskikbaar gestel deur die Nasionale Universiteit van Singapoer tydens ’n navorsingsbesoek daar. / Kule thesisi isimo sezinhlangano ezingaphansi kwesivumelwano sesikhathi esinqunyiwe, ngaphansi kwesigaba 14 koMthetho 68 ka 2008, uMthetho weZokuvikelwa koMthengi uhlaziywa ngendlela egxekayo. Inhloso yalolu cwaningo ukusungula ukuthi mhlawumbe lezi zinhlangano ezingaphansi kwesivumelwano sesikhathi esinqunyiwe sivikeleke kangcono ngaphansi kwesigaba 14 se-CPA uma kunesidingo sabathengi sokuqedwa kwesivumelwano esencike phezu kokwehluleka ukwenza umsebenzi waloyo ongumthumeli wempahla, okwehlukile emthethweni owejwayelekile. Okwesibili, le thesis iphenya ukuthi mhlawumbe isikhathi isikhathi esinde sesivumelwano sesikhathi esinqunyiwe kufanele sincishiswe ngokomthetho oshayiwe. Izinto ezahlukahlukene ezithinta lezi zivumelwano, njengesibonelo, inkululeko yokungena esivumelwaneni pacta servanda sunt, kanye nesivumelwano ezingaguquki, kuyizinto ezibhekwayo. Isimo seNingizimu Afrika siqhathaniswa nesimo sezwe laseSingapore ngaphansi koMthetho wezokuVikelwa kwabaThengi (Fair Trading), kanye nasezweni laseUnited Kingdom ngaphansi koMthetho owaMalungelo abaThengi, ukuthola umqondo kanye nokuhlola izimiso ngaphansi kwesigaba 14 soMthetho 68 ka 2008, uMthetho oVikela abaThengi ukuthola ukuthi ngabe iNingizimu Afrika kukhona ekuzuzile kwizifundo ezifundwe kulezi zakhiwo zemithetho. Okokugcina, izichibiyelo ezisuselwe kwimigomo mayelana nalokho okushiwo yi-CPA inconywe ukuthi yenze ngcono isimo sezinhlangano ezingaphansi kwezivumelwano zesikhathi esinqunyiwe ukuletha izisombululo ezingcono kanye nokuqinisekisa ukuthi kulandelwa izinhloso kanye nemisebenzi yoMthetho 68 ka 2008, okunguMthetho oVikela abaThengi kanye nemihlahlandlela yezizwe zomhlaba.
