The mediating impact of monetary incentives : A study on consumers’ willingness to recycle sWEEELindholm, Emil January 2022 (has links)
E-waste is a growing problem across the world. With a higher living standard comes an increase in electronic product usage and subsequently discarding, which leads to negative environmental and human impact when discarded incorrectly. This improper discarding of E-waste is most prevalent in the small equipment category. Based on earlier research on reducing improper disposal of E-waste and characteristics of inducing behavioural change, this study examines the mediating impact of monetary incentives on people's willingness to recycle small waste electrical and electronic equipment (sWEEE) through a deposit-refund system (DRS). The study uses an extended theory of planned behaviour (TPB) to examine the mediating effect of monetary incentives and aims to examine which of the influencing factors of attitude, subjective norm and perceived behavioural control has the biggest impact on willingness to recycle sWEEE using a DRS. Data was collected through a quantitative method with a survey that was shared on social media. A sample of 152 was realised and the data was analysed by means of structural equation modelling, employing a partial least squares method using SmartPLS. The results showed that attitude, subjective norms and perceived behavioural control did not have a significant impact on willingness to recycle sWEEE using a DRS. Furthermore, the mediating effect of monetary incentives showed that monetary incentives decrease willingness to recycle, which in turn impacts recycling behaviour. As the results are contrary to extant research, the findings warrant further research into the area.

EBSD Investigation of High-Temperature Magnetite from Apatite-Iron-Oxide Deposits: Implications for the Formation of Giant Kiruna-Type Deposits / EBSD-undersökning av högtemperatur magnetit från apatit-järnmalmsfyndigheter: Implikationer för bildningen av gigantiska fyndigheter av Kiruna-typHenriksson, Jens January 2022 (has links)
European iron production is to a large extent dependant on massive Kiruna type apatite-iron ore deposits. In this contribution, high-temperature magnetite samples from apatite-iron-oxide deposits are investigated by means of Electron Backscattered Diffraction. However, the origin of Kiruna-type deposits is still unresolved. Although magmatic processes are likely, it is not clear how small-scale processes can form giant Kiruna-type deposits. The sample suite consists of magnetite samples from six global apatite-iron-oxide deposits: the famous Kiirunavaara deposit and the Malmberget deposit, both located in northern Sweden, the Grängesberg deposit in south-central Sweden, the iconic El Laco deposit in north-eastern Chile, the Bafq deposit in central Iran, and the Varena deposit in south Lithuania. Fe-O systematics has been conducted to complement existing δ18O and δ56Fe isotope data and ensure magmatic origin of the samples from the Malmberget deposit (n=6) and the Varena deposit (n=2). This is the first effort to characterise magnetite samples from apatite-iron-oxide deposits utilising EBSD. In total, twelve EBSD maps have been produced. Evaluation of the EBSD data have been performed to quantify the preferred orientation of the magnetite crystals. Four deposits, with Kiirunvaara being the prime example, shows no preferred alignment of the magnetite crystals. Whereas the El Laco samples exhibits a strong preferred alignment of {111}. The EBSD data from magnetite samples in equilibrium with a magmatic source indicate that apatite-iron-oxide deposits are formed in both intrusive and extrusive environment and that magmatic crystal accumulation is a key process in aggregating magnetite to form large and even giant Kiruna-type deposits. / Europeisk järnmalmsproduktion är i stor utsträckning beroende av massiva apatit-järnmalmsfyndigheter av Kiruna-typ. I det här arbetet, undersöks magnetitprover av hög-temperaturs ursprung från olika apatit-järnmalmsfyndigheter med Elektron Bakåtspridande Diffraktion. Bildningsmekanismen av apatit-järnmalmsfyndigheter av Kiruna-typ är än idag oklar. Bevisen indikerar magmatiska bildningsprocesser, det är dock fortfarande oklart hur småskaliga magmatiska processer bildar gigantiska apatit-järnmalmsfyndigheter av Kiruna-typ. Provserien består av magnetitprover från sex globala apatit-järnmalmsfyndigheter: den världsberömda Kiirunavaara fyndigheten och Malmberget fyndigheten, båda lokaliserade i Norrbotten, Sverige, Grängesberg fyndigheten i Bergslagen, Sverige, den ikoniska El Laco fyndigheten i nordöstra Chile, Bafq fyndigheten i centrala Iran, och Varena fyndigheten i södra Litauen. För att fastställa ett magmatiskt ursprung och komplettera befintlig δ18O och δ56Fe isotopdata har Fe-O-systematik utförts på magnetitproverna från Malmberget (n=6) och Varena (n=2). Det här är den första dokumenterade EBSD-undersökningen av magnetitprover från apatit-järnmalmsfyndigheter. Totalt tolv EBSD-kartor har producerats. Utvärdering av EBSD-data har utförts för att kvantifiera den föredragna riktningen på magnetitkristallerna. I fyra fyndigheter, med Kiirunvaara som typexempel, uppvisar magnetitkristallerna ingen föredragen riktning, medan magnetitproverna från El Laco uppvisar en tydlig föredragen riktning längs {111}. EBSD-data från magnetitprover i jämnvikt med en magmatiskkälla påvisar att apatit-järnmalmer bildas i både intrusiva miljöer och extrusiva miljöer och att magmatisk ackumulation är en nyckelprocess för att aggregera magnetitkristaller och bilda stora till gigantiska apatit-järnmalmsfyndigheter av Kiruna-typ.

Pantsystem för återbruk av emballage inom E-handel : En möjlig lösning för en mer hållbar E-handel / A deposit-refund system for reuse of packaging in E-commerce : A possible solution for a more sustainable E-commerceApelgren, Julia, Kronvall, Sara, Surtevall, Ellen January 2021 (has links)
Den omstrukturering som detaljhandeln genomgått under de senaste åren i och med digitaliseringens framskridning har även resulterat i en kraftig tillväxt inom e-handeln. Dettahar även inneburit en ökad tillverkning av emballage med en tillväxt som fortsatt förväntas öka även i framtiden. Denna tillväxt sätter ökad press på hur produkter inom e-handeln paketeras samt hur emballagen hanteras och därmed fnns det ett behov av att göra e-handeln mer hållbar. Rapporten ämnar att undersöka om ett pantsystem för återbruk av emballage från e-handeln kan vara en del av det, utifrån de tre aktörerna Konsument, Företag och Transportör och följande fem dimensioner: Organisation, Ekonomi, Beteende, Material och Teknik. Resultatet visar att de tre aktörerna kommer möta både utmaningar och möjligheter samtidigtsom förutsättningar har identiferats för att det utredda pantsystemet ska kunna implementeras. För konsumenten är en av de främsta utmaningarna att få konsumenten att gå och panta sitt emballage. En annan stor utmaning är att hitta en nivå på pantsumman som ger konsumenten tillräckliga ekonomiska incitament att vilja gå att panta samtidigt som den inte kan vara för hög eftersom det kan skapa en ovilja att delta i pantsystemet. Företaget ges en möjlighet att erbjuda konsumenter ett enkelt sätt att göra hållbara val samtidigt som deras lönsamhet till stor del ärberoende på att konsumenter inte ser panten som en extra kostnad och därför väljer att avstå från att handla samt att de faktiskt väljer att panta emballaget över att återvinna. För transportören uppstår en möjlighet att utveckla en ny hållbar tjänst samtidigt som det uppstår kostnader på grund av merarbete. Kostnaderna förväntas att täckas av den vinst som uppstår om en konsument inte lämnar tillbaka sitt emballage - väljer att inte panta. Huruvida det vore möjligt att implementera ett pantsystem och om det är en möjlig dellösning för en mer hållbar e-handel går inte att svara på utifrån denna rapport. Detta eftersom det skulle krävas mer information, djupare analyser samt ett pilotprojekt för att kunna testa pantsystemet. / As retail has been restructured with digitalisation, e-commerce has seen strong growth. This has implied a strong increased production of packaging, and is expected to continue to do so in the future. This growth has increased the pressure on how products in e-commerce are packagedand how packaging is handled, and thus there is a need to make e-commerce more sustainable.This report intends to investigate whether a deposit refund system for reuse of packaging from e-commerce can be part of this, based on the three actors: Consumer, Retailer and Carrier, and five dimensions: Organization, Economy, Behavior, Material and Technology. The results show that the three actors will face both challenges and opportunities at the same time as prerequisites have been identifed for the investigated deposit refund system to be implemented. For the consumer, one of the main challenges is to get the consumer to return their packaging for reuse instead of recycling. Another major challenge is to find a level of the deposit that gives the consumer suffcient financial incentives to be willing to return their packaging. If it is too high it can create a reluctance to participate in the deposit system. The retailer is given an opportunity to offer consumers an easy alternative to make sustainable choices. However their profitability is largely relying on consumers not seeing the deposit as an extra cost and therefore choosing to refrain from shopping. For the carrier, an opportunity arises to develop a new sustainable service at the same time as the costs that arise due to extra work. These costs are presumed to be covered by the profit that occurs if the consumer fails to return their packaging. Whether a deposit refund system would be possible to implement or if it is a possible partial solution for a more sustainable e-commerce, cannot be deduced from this report. More information and deeper analyses would be required as well as a pilot project to test the deposit refund system.

Sedimentological Records and Numerical Simulations of the C.E. 1707 Hōei Tsunami in Southwestern JapanBaranes, Hannah 23 November 2015 (has links) (PDF)
A tsunami generated by the C.E. 1707 Hōei earthquake is largely thought to be the flood event of record for southwestern Japan, yet historical documentation of the event is scarce. This is particularly true in northwestern Shikoku within the Bungo Channel, where significant inconsistencies exist between historical records and model-derived tsunami heights. To independently assess flooding from the C.E. 1707 Hōei tsunami in the context of the region’s long-term flooding history, we present complementary reconstructions of extreme coastal inundation from three back-barrier lakes in the northern Bungo Channel: Lake Ryuuoo, Lake Amida, and Lake Kamega. At all sites, the most prominent marine overwash deposit of the past ~1,000 years, as defined by grain size, density, and geochemical indicators, is consistent with the timing of the 1707 tsunami, providing strong evidence that the event caused the most significant flooding of the last millennium in this region. At Lake Ryuuoo, modern barrier beach elevations and grain sizes in the tsunami’s resultant deposit provide ~4 m as the first physically based height constraint for the 1707 tsunami in the northern Bungo Channel.
Around 1,000 years ago, a concurrent and abrupt transition in lithology observed at all three sites is also consistent with rapid, regional geomorphic change. At Lake Ryuuoo, a marine overwash deposit comparable to the 1707 deposit directly overlies this transition. A 1,000-year-old lithological transition or deposit has not been observed at sites closer to the mouth of the Bungo Channel, suggesting that the deposit in Lake Ryuuoo is more consistent with a tsunami generated by local seismicity along the Japan Median Tectonic Line than with a Nankai Trough-derived tsunami. Our findings are significant in that they provide three new millennial-scale tsunami inundation reconstructions for a relatively understudied region of Japan, along with the first physically based height constraint for the Hōei tsunami in the northern Bungo Channel.

Skarn testing report: MAP002: D5.4Brosig, Andreas 12 March 2021 (has links)
An assessment of tin-skarn resources in the Erzgebirge, Germany, was conducted with the 3-Part Method. For this purpose a Grade-Tonnage Model for this deposit type was established. A literature review produced grade and tonnage data for 23 skarn deposits, of which 9 are in the assessment area. Based on an existing predictive map created with an AI algorithm, seven permissive tracts with a total area of 776 km² were defined. To estimate the number of undiscovered deposits a panel of five experts in the economic geology of the Erzgebirge was assembled. From the expert estimates and the newly developed Grade-Tonnage Model the undiscovered ore and metal tonnages in each permissive tract were evaluated. In four of the seven tracts the probability of the existence of at least one undiscovered deposit is estimated to be greater than 50%, in permissive tract 2 it is even greater than 90%. In each of these tracts, the median assessed undiscovered ore tonnages are several million tons and the tin resources exceed 10,000 tons. For the most perspective tract (Permissive tract 2) the median estimates are 40.6 Million tons of ore with a tin content of 114,000 tons. For tungsten (tonnages calculated as WO3) the numbers are slightly lower.
The results verify the high resource potential of tin skarns in the Erzgebirge and can be used to guide future exploration activities to the most economically promising permissive tracts.

A study of the New Basel Capital Accord and its impact on South Africa and other emerging marketsChadwick, Warren 12 1900 (has links)
Thesis (MBA)--Stellenbosch University, 2002. / ENGLISH ABSTRACT: The new Basel Capital Accord is intended to align capital adequacy of banks more closely with the key
components of banking risk and to provide incentives for banks to improve their risk measurement and
management capabilities. This has important implications for banks, particularly in the area of credit risk
management.
The purpose of this study is to take an in-depth look at the implications for banks in the area of credit
risk management and the choice of approach (i.e. standardised versus internal ratings based approach)
to be adopted. These changes in approach to credit risk will have broader economic implications and
the study will in its final analysis explore these in the context of South Africa, as an emerging market.
The study is split into three sections:
Section A
• Introduction and background to the New Basel Capital Accord;
• Detailed overview on the New Basel Capital Accord with a particular emphasis on the internal
ratings based approach to calculating minimum capital.
Section B
An in-depth discussion of credit risk management and the practical implications of moving towards an
internal ratings based approach, which will eventually allow banks to take on a full portfolio approach to
credit risk management. This will enable banks to manage credit risk across sub-portfolios and set
economic capital based on the portfolio loss distribution of the banks entire lending book. This is an
extremely important development in credit risk management and as a consequence is covered in some
detail.
The adoption of an internal ratings based approach offers significant rewards in the form of lower
statutory capital. A profile of the current capitalisation of SA banks is provided followed by the likely effect of the standardised versus the internal ratings based approach to credit risk management, on the
minimum level of statutory capital of banks.
Section C
The final section covers the envisaged macro effects of the New Accord on emerging markets (procyclical
trends, lending concentrations, foreign capital flows and bank failures) with specific comment
provided on the implications for the SA banking environment and economy.
In conclusion, South African banks should as a priority move towards an internal ratings based
approach to credit risk management in order to benefit from the lower statutory requirements, which
accrue in the advanced phase. While the accord is likely to impact significantly on emerging markets,
South Africa fortunately has a sophisticated banking system by international standards, making the
adoption of an internal ratings based approach by the larger SA banks inevitable. The benefits for
smaller banks are questionable and at this stage they are unlikely to move beyond the standardised
approach, unless compelled to do so. / AFRIKAANSE OPSOMMING: Die "New Basel Capital Accord" het ten doel om die kapitaal vereistes neergelê vir banke meer in lyn te
bring met die risiko komponent gekoppel bankwese. Dit hou 'n belangrike implikasie vir banke in en
verskaf voorts ook 'n dryfveer vir banke om die bestuur van krediet risiko en algehele
bestuursvaardighede te verbeter.
In hierdie studie word 'n indiepte ondersoek onderneem aangaande die implikasie op banke van krediet
risiko-bestuur en die keuse van die benadering wat gevolg word. Hierdie veranderings in die
benadering (dws.standard teenoor interne-graderings benadering) tot krediet risiko hou breër
ekonomiese implikasies vir banke in. Hierdie ekonomiese implikasies op SA as 'n ontwikkelende mark
word in die finale analise ondersoek.
Die studie kan in drie afdelings verdeel word:
Afdeling A:
• Inleiding en agtergrond tot die "New Basel Capital Accord" en
• 'n Gedetaileerde oorsig van die "New Basel Capital Accord" met spesifieke verwysing na die
interne-graderings benadering om die minimum vereiste kapitaal te bepaal.
Afdeling B:
Hierdie afdeling ondersoek krediet risiko bestuur en die praktiese implikasies van die
aanvaarding/instelling van 'n interne graderings benadering, en die effek wat dit sal hê op 'n totale
portefeulje benadering tot krediet risiko. Die gevolg is dat banke krediet risiko oor sub-portefeuljes sal
kan bestuur en kapitaal vlakke vasstel gebaseer op verwagte portefeulje verliese. Hierdie is 'n
belangrike ontwikkeling in krediet risiko bestuur en word vervolgens in diepte behandel.
Die aanvaarding van 'n interne-graderings benadering tot gradering hou voordele in vir banke in die
vorm van laer statutêre kapitaal vereistes. 'n Profiel van die kapitalisasie van SA banke word verskaf, gevolg deur die verskil in die effek van die standaard benadering tot die interne
graderings benadering op krediet risiko bestuur en die vereiste minimum statutêre kapitaal.
Afdeling C:
Die finale afdeling ondersoek die beoogde makro ekonomiese effek van die "New basel capital Accord"
op ontwikkelende marke (pro-sikliese neiging, lenings konsentrasies en bank mislukkings) met
spesifieke verwysing na die implikasies op SA bankwese en ekonomie.
Ter afsluiting moet SA banke so spoedig moontlik die interne-graderings benadering tot krediet risiko
aanvaar om voordeel te trek uit die laer kapitaal vereistes wat "ophoop in die gevorderde stadium." Daar
word verwag dat die "New Basel Capital Accord" 'n wesenlike invloed op die ontwikkelende mark sal hê.
SA het egter 'n gesofistikeerde en gevestigde bankstelsel wat goed vergelyk met internasionale
standaarde. Die aanvaarding van 'n interne-graderings benadering deur die die groter SA banke is
onafwendbaar. Die voordele wat dit vir kleiner banke inhou kan bevraagteken word en is op hierdie
stadium onwaarskynlik dat so 'n benadering deur hulle geïmplimenteer sal word.
