Making urban fishing sustainable. A case study of fishing practices and management in the city of HamburgGellers, Sören January 2022 (has links)
Ongoing urbanization and the demand for food, water and recreation influence the sustainability of blue urban spaces. Fishery is a prominent use of urban blue space and can cause pressure on urban nature, its water bodies and fish. This growing pressure requires more attention to how urban dwellers use and value this space and requests smart fishing management for urban areas. To improve knowledge on how to realise sustainable urban fishing, this thesis used an interview study in the city of Hamburg in Germany. Six fishers, two representatives of fishing clubs and one representative of the fishing club association, were interviewed, and the results were combined with observations during one and a half weeks of field study and literature review. The study shows that Germany uses a distinctive approach regarding fishing management with a general ban on catch-and-release and strict regulations. Since fishing law is a state law, the federal state of Hamburg is responsible for its fishing management. The main managing tool is the new fishing law from 2019, developed with scientists and stakeholders to improve fishing in an ethical and sustainable way. The stakeholder’s different impacts on and interests in the rivers of Hamburg have to be respected and are shown in this thesis. The study concludes that management practices have to be managed adaptive to consider changing environmental conditions. Generic fishing management practices (e.g., education of fishers) are limited, while most have to be individually adapted for the environment and fishing culture (e.g., fish protection).

Making Culture - Continuous re-appropriation of a city piecePuttkammer, Julius January 2022 (has links)
I understand the site of the former Schilleroper as a piece of the city with an unsettled history of trying, failing and trying again. Despite its difficult history of ups and downs, the Schilleroper has been a meaningful and popular place within its neighbourhood. A place of affordable, low threshold culture for the former working class residents. Even long after its life as a venue for large cultural events in the grand hall, it has been a lively public place in the area.Decades of neglect and decay later, the building is facing an uncertain future and it remains unclear, what, if anything, will be done to preserve it. The proposal suggests a (more or less) temporary use of the place as a continuous construction site of cultural making. Instead of aiming for a finalized architectural proposal, it describes a process of change and adaptation that, started by the suggested architectural interventions, could eventually develop its own self-renewing dynamics. It aims to offer a place that allows to be inhabited, appropriated and altered by its users. A place that not only accepts these notions, but actively depends on them. A place that the people of Hamburg can call their own.

It is green, but is it just? : A critical investigation of distributive, procedural and corrective urban environmental justice dimensions in Hamburg, GermanyBüker, Hannah Maria January 2024 (has links)
In this thesis, the public green space provision in Hamburg, Germany is critically examined and put into context by social indicators relating to social class and ethnic background. Urban green spaces offer a variety of benefits for citizens, ranging from recreation, improving physical and mental health, contribution to urban cooling and climate adaptation as well as providing spaces for biodiversity. Yet, provision and access to public green space is not always equal. This is reflected in the concept of urban environmental justice, which acknowledges that not all societal groups equally benefit from environmental services nor are equally affected by the burdens of environmental pollution. Urban environmental justice is used in this thesis to holistically assess public green space provision, from a distributive, procedural and corrective justice dimension. These dimensions relate to how public green space is distributed in the city, how policies surrounding green space incorporate urban environmental justice concerns, and lastly what measures are in place for correcting potential injustices. The thesis employs a mixed method approach. Critical mapping through QGIS was applied to showcase the distribution and proximity to public green space in the various neighbourhoods in Hamburg. Following this, a policy analysis was performed to investigate the procedural justice dimension. Lastly, semi-structured interviews with five planners and two activists were conducted to illuminate measures for correcting urban environmental injustices related to green space provision. The findings suggest that public green space is not evenly distributed, and issues of access exist in Hamburg. Procedural justice is not fully achieved as a legal framework for urban environmental justice is lacking and the existing policies do not consider the concept adequately. Simultaneously, both supporting and hindering measures for correcting urban environmental injustices exist and corrective justice is not fully achieved either. Overall, the discourse surrounding urban environmental justice should be advanced in Germany and more awareness needs to be raised.

Offshore-Containerterminals als Transshipment-Hub - dargestellt am Beispiel der Deutschen Bucht / Offshore-Containerterminals used as transshipment-hub - shown on the example of the German BightReise, Sönke 23 July 2005 (has links) (PDF)
Deutlich ansteigende interkontinentale Handelsbeziehungen bilden die wesentliche Grundlage das Wachstum der Containerschifffahrt. Die Schnittstelle der Containerschifffahrt zu den landgebundenen Verkehrsträgern bilden Containerterminals. Deren Entwicklung muss im Zusammenhang mit der Containerschifffahrt gesehen werden. Die Entwicklung des Containerschifffahrtsmarktes wird sich auch in Zukunft weiter dynamisch fortsetzen. Prognosen zur Umschlagsentwicklung sind für die Containerterminals von besonderem Interesse, da die Containerterminals bestrebt sind, genügend Kapazitäten bereitzustellen. Im Umfeld eines Containerterminals sowie in ihnen selbst können diverse Kapazitätsengpässe entstehen. In vielen Fällen ist dringender Handlungsbedarf hinsichtlich der Beseitigung von potenziellen Engpässen gegeben. Eine Option stellt dabei der Neubau von Containerterminals dar. Der Hafenbau wird in dichtbesiedelten Räumen zunehmend schwieriger und teurer. Die aus heutiger Sicht zur Verfügung stehenden Flächen werden langfristig nicht ausreichen, um das Umschlagsaufkommen der Zukunft zu bewältigen. Deswegen kann die Errichtung von herkömmlichen Containerterminals langfristig nicht als ausschließliche Option zur Beseitigung von Umschlagsengpässen angesehen werden. Das Konzept eines Offshore-Containerterminals (OCT) stellt einen alternativen Ansatz dar, der zukünftige Engpässe vermeidet oder ihre Auswirkungen mindert. Ziel des Konzepts ist die Verlagerung von Transshipments von den herkömmlichen Containerterminals auf einen OCT. Dieses Konzept wird auf seine wirtschaftliche Tragfähigkeit untersucht. Letzlich stellt das Konzept des OCTs als Transshipment-Hub eine Möglichkeit dar, die unter heutigen Verhältnissen zwar unrentabel erscheint, unter zukünftigem Expansionsdruck und Kostensteigerungen bei der Erschließung neuer Terminalflächen jedoch als Konzept ökonomisch konkurrenzfähig sein kann und eventuell ohne Alternative ist.

Rapid estimation of lives of deficient superpave mixes and laboratory-based accelerated mix testing modelsManandhar, Chandra Bahadur January 1900 (has links)
Doctor of Philosophy / Department of Civil Engineering / Mustaque Hossain / The engineers from the Kansas Department of Transportation (KDOT) often have to decide whether or not to accept non-conforming Superpave mixtures during construction. The first part of this study focused on estimating lives of deficient Superpave pavements incorporating nonconforming Superpave mixtures. These criteria were based on the Hamburg Wheel-Tracking Device (HWTD) test results and analysis. The second part of this study focused on developing accelerated mix testing models to considerably reduce test duration.
To accomplish the first objective, nine fine-graded Superpave mixes of 12.5-mm nominal maximum aggregate size (NMAS) with asphalt grade PG 64-22 from six administrative districts of KDOT were selected. Specimens were prepared at three different target air void levels @ N[subscript]design gyrations and four target simulated in-place density levels with the Superpave gyratory compactor. Average number of wheel passes to 20-mm rut depth, creep slope, stripping slope, and stripping inflection point in HWTD tests were recorded and then used in the statistical analysis. Results showed that, in general, higher simulated in-place density up to a certain limit of 91% to 93%, results in a higher number of wheel passes until 20-mm rut depth in HWTD tests. A Superpave mixture with very low air voids @ N[subscript]design (2%) level performed very poorly in the HWTD test.
HWTD tests were also performed on six 12.5-mm NMAS mixtures with air voids @ N[subscript]design of 4% for six projects, simulated in-place density of 93%, two temperature levels and five load levels with binder grades of PG 64-22, PG 64-28, and PG 70-22.
Field cores of 150-mm in diameter from three projects in three KDOT districts with 12.5-mm NMAS and asphalt grade of PG 64-22 were also obtained and tested in HWTD for model evaluation. HWTD test results indicated as expected. Statistical analysis was performed and accelerated mix testing models were developed to determine the effect of increased temperature and load on the duration of the HWTD test. Good consistency between predicted and observed test results was obtained when higher temperature and standard load level were used. Test duration of the HWTD can thus be reduced to two hours or less using accelerated mix testing (statistical) models.

Logotherapy and imagery work: the contribution of Boeschemeyer’s ‘Wertimagination’Meyer-Prentice, Monika 14 September 2011 (has links)
In this qualitative, interpretive study a new and promising imagery
technique, called Wertimagination (WIM®) [Value-Oriented Imagery] was
researched. It was developed by the logotherapist Uwe Boeschemeyer in
Germany. At the main focus of this study are the psychotherapeutic work
experiences of logotherapists applying WIM®. Their perceptions with
regard to Wertimagination’s potencies, limitations and its overall
contribution to Logotherapy are explored. Eight semi-structured expert
interviews were conducted with German logotherapists offering WIM® at
their practice. The interview contents are analysed and compared with
supplementing perspectives: with Wertimagination experiences reported
by other (logo)therapists, by clients and by the developer of the method
(Boeschemeyer), extracted from the existing body of literature. The results
show that Value-Oriented Imagery by all three researched parties –
(logo)therapists, clients and its developer – is experienced to be a high
potential logotherapeutic, salutogenetic (resources-oriented) approach
contributing inter alia towards a person’s inner meaning finding, selfacceptance
and trust in life. / Psychology / M.A. (Psychology)

Expoentes mercantis e dinâmica de negócios: a família Dias de Milão (1580-1624) / Exponents market and business dynamics: the family Dias of Milan (1580-1624)Ricardo, Silvia Carvalho 28 August 2014 (has links)
A expansão marítima dos séculos XV e XVI reconfigurou as atividades mercantis na Europa e levou a difusão dos centros de comércio e das fontes de mercadorias em novas praças na Ásia, na América e na África. O trato transcontinental e as finanças, que ganharam complexidade, concretizaram-se nas relações entre as redes de comércio com atuação global. Portugal foi o nascedouro de grande parte dessas redes familiares que se multiplicaram e passaram a ter negócios em todas as frentes do trato colonial. No início do século XVII, os grandes cabedais lusos transferiram-se para Amsterdã e Hamburgo. Famílias cristãs-novas destacaram-se no trato mercantil, entre elas a dos Dias de Milão perseguida e presa pela Inquisição , que reapareceu em Amsterdã e Hamburgo com grande atuação no comércio internacional / The maritime expansion that occurred during the XV and XVI centuries reconfigured the mercantile activities in Europe and led to the dissemination of commercial centers and sources of commodities on new places of Asia, America and Africa. The transcontinental treat and finances gained complexity that substantiated itself in global trade networks. Portugal was the incubator of a great deal of those multiplying family networks that started to have businesses in all fronts of the colonial treat. At the beginning of the XVII century, the great Portuguese estates were transferred to Amsterdam and Hamburg. New-Christian families had significant importance in commercial dealings, among them the Dias de Milão family, persecuted and arrested by the Inquisition that reappeared in Amsterdam and Hamburg with great outwork on international commerce
