Tireless in His Service: Rasmus Andersen, Pastor and Author 1878-1924
No full textOf the four founders of the Danish Lutheran Church in America in 1872, the one concerning whom the most information exists is Rasmus Andersen. Yet it has been my observation that comparatively little is known about him. A reason for this is that, to my knowledge, no comprehensive biography exists, and there is almost nothing available in the English language. Most of the material that does exist is to be found in the Danes World Wide Archives ( Udvandrerarkivet ) in Aalborg, Denmark. According to Birgit Flemming Larsen, who oversees that archive, the Andersen collection is the largest at the Aalborg archive. It consists of 104 archival boxes, filled with books, letters, diaries, memoirs, ministerial records, copies of letters sent, unpublished manuscripts and much more. The Danes World Wide Archives constitutes a treasure trove for the researcher who is interested in Rasmus Andersen

Evaluating environmental policy instruments for ships [Elektronisk resurs]
No full textShipping is crucial for international trade, but has significant environmental impacts at local, regional, and global levels. Ship operations contribute to climate change, air pollution, and marine ecotoxicity through emissions of greenhouse gases, sulfur oxides, nitrogen oxides, particulate matter, and contaminants from sources like antifouling paints. Although the International Maritime Organization (IMO) aim to mitigate environmental impacts from shipping, the sector’s environmental policies often lag behind land-based measures, highlighting the need for stronger policies and comprehensive policy evaluations. This thesis investigates the effectiveness of environmental policy instruments in reducing emissions from shipping, with a focus on three policy cases addressing different policy approaches: port and fairway fee discounts (Paper I), inclusion of shipping in the EU Emission Trading Scheme (EU ETS) (Paper II), and the IMO global sulfur cap (Paper III). By examining these policy cases, the thesis analyzes how these policies influence shipping companies´ decisions to invest in different abatement strategies. Additionally, this thesis evaluates how different national, regional, and global policy instruments, both individually and in combination, influence shipowners' decisions to invest in abatement strategies. It also examines the subsequent impact on emissions beyond those directly targeted by the policies. The first case (Paper I), which addresses Swedish environmentally differentiated port and fairway fees, shows that the discounts provided to shipowners are insufficient by themselves to motivate significant investment in abatement strategies. The second case (Paper II) evaluates the inclusion of shipping in the EU ETS, indicating that while abatement strategies such as batteries, e-methanol, and liquid hydrogen show potential, their high costs, in combination with the current EU ETS price, hinder broad adoption. Bio-methanol can for some ships and scenarios be a cost-effective fuel choice, however biofuels are limited by the amount of sustainably sourced feedstock. Overall, the Swedish environmentally differentiated port and fairway fees (Paper I) and the EU ETS policy cases (Paper II) highlight that while environmental policies are relevant, their current designs often fail to provide sufficient financial incentives for significant technological investment and emission reductions. The third case (Paper III) focuses on the IMO global sulfur cap, which successfully has reduced sulfur oxides emissions to the atmosphere but instead lead to a widespread use of scrubbers, generating new environmental concerns from scrubber water discharges. The results also highlight that combining the effects of the Energy Efficiency Design Index, a potential global scrubber ban, and an expanded EU ETS (including 100% of incoming and outgoing traffic) have synergistic effects that will reduce abatement costs for shipowners and thereby stimulate emission reductions or directly reduce emissions. However, abatement costs per amount avoided CO2-emissions for retrofitting to use e-methanol are still more than four times higher than the current EU ETS-price. Furthermore, the results show that including smaller ships in EU ETS is important for reducing direct GHG emissions, further highlighting the need for a broader regulatory scope
The Blood Wedding Ring, Assessing the Life Cycle Lives Lost in Gold Jewelry Production
No full textThis study investigates the human health impact of gold jewelry during its entire life cycle. Gold has many negative impacts on human health during its life cycle, such as emissions and accidents during different stages in the life cycle. There are also indications that mining of different minerals leads to conflicts and that minerals, such as gold, are used for financing military activities resulting in people getting killed, injured or displaced. Especially the eastern part of the Democratic Republic of the Congo (DRC) is associated with conflict gold. Consequently, gold produced in the DRC is the main focus of this study, while gold produced in Sweden and South Africa
are included for comparison.The main method of this thesis is an attributional life cycle assessment (LCA) with an
expanded social perspective. The disability-adjusted life years (DALY) is the indicator, and the results are quantified for the amount of gold in one typical wedding
ring and per kg of gold. The indicator DALY is chosen since it allows for considering different types of causes of death and impairment, including conflicts, occupational
hazards and environmental hazards. The aim is not to reach an exact figure of how many years of life that are lost, but rather to evaluate the magnitude of different
processes. The three types of human health impacts that are quantified in this study are: impacts from environmental emissions, impacts from work environment accidents, and impacts from conflict. About 0.4 years of life were lost per wedding ring for gold produced in the DRC, which is several orders of magnitude larger than the impact of gold produced in South Africa and Sweden. The calculated number for life years lost is very high for such a small amount of gold, creating credibility for the title of this tudy: “the blood wedding ring”. The impact from the conflict is several orders of magnitude larger than the impact in any other process. If the impact assessment result from the conflict is excluded from the results, the emissions occurring at the extraction and processing of gold instead had the greatest impact, several orders of magnitude larger than any other process. In particular, mercury emissions to air had a high impact on human health during the processing of gold in artisanal mining in the DRC. The other processes
have more minor impacts on human health.
Sensitivity analyses were conducted to evaluate data gaps and uncertainties. These analyses in general showed that the results of the impact assessment are reasonable.
The overall conclusion is that even though the results are uncertain, the conflict’s impact on human health is still several magnitudes larger than those of all other processes evaluated in the study
Perehdytysopas Pirkanmaan saneerauspalvelu Oy:lle
No full textTämän opinnäytetyön tarkoituksena on perehdytysopas toimeksiantajayritys
Pirkanmaan saneerauspalvelu Oy:n uusille työntekijöille. Yrityksellä ei ole aiemmin ollut perehdytysopasta työntekijöilleen, vaan uusien työntekijöiden perehdytys on toteutunut kokeneempien työntekijöiden toimesta työmailla. Lisäksi perehdytyksen yhteydessä yrityksen hallilla on pidetty perehdytyskierros, jolloin työnjohto on näyttänyt eri materiaalien sijainnit, kertonut lyhyesti yleisiä asioita yrityksestä ja työntekijän työtehtävistä.
Tämän opinnäytetyön tavoitteena on, että jatkossa uusien työntekijöiden töiden aloittaminen on helpompaa sekä selkeämpää. Lisäksi tavoitteena on myös vähentää työnjohdon sekä kokeneempien työntekijöiden kuormitusta uusien työntekijöiden perehdyttämisessä.
Opinnäytetyössä perehdyttämisen lisäksi työssä käsitellään rakennusalan työturvallisuutta, työsuoritteita ja niissä käytettäviä materiaaleja. Työssä tarkastellaan myös työkoneiden ja- välineiden turvallista käyttöä, Easoft-toiminnanohjausjärjestelmää sekä laadunvarmistukseen liittyviä asioita. Lopuksi pohditaan mahdollisia jatkotoimenpiteitä. Tämän perehdytysoppaan tekemiseen on kerätty tietoa kirjallisista lähteistä, haastateltu pitkään yrityksessä olleita ammattilaisia sekä tämän opinnäytetyön tekijän kokemuksia rakennusalalta.
Tulevaisuudessa perehdytysopas on tarkoitus jakaa uusille työntekijöille (työsopimusta kirjoittaessa) sekä uusille vuokratyöntekijöille. Uusien työntekijöiden sekä vuokratyöntekijöiden tulee tutustua perehdytysoppaaseen ennen varsinaisten töiden aloitusta.
Perehdytysopasta voidaan tulevaisuudessa muokata työnjohdon toimesta työntekijöiltä kerätyn palautteen perusteella. Lisäksi opasta muokataan, mikäli yrityksen toimintatavat ja työsuoritteet muuttuvat.The purpose of this thesis is an orientation guide for the new employees of the employer company Pirkanmaan Saneerauspalvelu Ltd. The company has not previously had an orientation guide for its employees, so the orientation of new employees has been implemented by more experienced workers in the workplace. In addition, during the orientation an induction tour has been held in the hall, where the supervisors have shown the locations of different materials, briefly told general things about the company and which tasks belong to whom. The objective of this thesis is to make it easier and clearer for the new employees to start working. In addition, the aim is to reduce the burden on supervisors as well as more experienced employees when orienting a new employee.
In addition to orientation, this thesis deals with construction occupational safety, work processes and the materials used. The work also examines the safe use of machines and equipment used to work, ERP system called Easoft and issues regarding quality assurance. In the end potential follow-ups are pondered. To create this orientation guide information was collected from various written sources. In addition, professionals working in the company has been interviewed and the own experiences of the author of this thesis on the construction industry has been collected.
In the future, the orientation guide will be distributed to new employees when writing an employment contract and also for new agency workers. The new employees as well as the agency workers should read the orientation guide before starting the actual work.
In the future, the orientation guide can be modified by the management based on feedback from employees. In addition, the guide will be modified according to the changes of the company's policies and processes
Measures to Reduce Emissions from Ships A case study: An early evaluation of the potentials of digitalization and changed framework for port calls in the Port of Gävle.
No full textMany ports today want to improve the information flow in the logistics chain to be able to make port calls more efficient and thereby reduce the waiting times for ships, terminals and other operators in the logistics chain. The Port of Gävle is part of two ongoing projects, where digital tools and improvement of the current regulatory and structural framework in the port are being evaluated. The example calculations made in this study show that the potential to reduce emissions at sea is great even at minor speed reductions. For example, the annual greenhouse gas emissions for all incoming vessels would decrease by 8 300 tonnes of CO2-e if the ships would lower their speed at sea from last port by only 5%. This can be compared to effects from a shorter time at berth that not only can reduce emissions from ships quayside but also from ships at anchor, due to shorter waiting times. The potential reduction with 7% shorter times at berth is between 600 and 900 tonnes of CO2-e/year and the reduction at anchor is estimated to be between 825 and 3 860 tonnes of CO2-e/year.The new digital solutions in combination with a new port framework open the possibility for ports to improve planning and communication of time slots at quay for arriving ships. With less time spent in port and guaranteed time slots at arrival, the ships no longer must compete to get to the port first and can sail in reduced speed at sea

Bibliometric author evaluation through linear regression on the coauthor network
No full textThe rising trend of coauthored academic works obscures the credit assignment that is the basis for decisions of funding and career advancements. In this paper, a simple model based on the assumption of an unvarying “author ability” is introduced. With this assumption, the weight of author contributions to a body of coauthored work can be statistically estimated. The method is tested on a set of some more than five-hundred authors in a coauthor network from the CiteSeerX database. The ranking obtained agrees fairly well with that given by total fractional citation counts for an author, but noticeable differences exist
Rasmus Sorensen and Danish Emigration, 1847-1863
No full textProbably no individual played a more seminal role in the limited Danish emigration to North America before and during the Civil War than Rasmus Sorensen. From the late 1840s until the early 1860s this author, educator, politician, and social reformer led three groups of his countrymen to Wisconsin and, through numerous booklets, speeches, and letters encouraged others to settle elsewhere in the United States and Canada. Yet Sorensen has generally been little more than a supernumerary in the historiography of this transatlantic migration. Its pioneering historian, Peter Sorensen Vig, devoted twelve pages to him in his mammoth compendium, a dozen more than John Bille allowed him in his disjoint narrative of 1896. Arne Hall Jensen described Sorensen \u27s life in two paragraphs in 1937, giving various biographical details without interpreting their significance. There is little to indicate that the recent revival of interest in the Danish-American field will reverse this long tradition of neglect. In his monumental study of emigration from Denmark, Kristian Hvidt relates his activities in a scant paragraph, perhaps justifiably, because Sorensen \u27s lifespan fell completely outside Hvidt\u27s chronological framework
