An assessment of the economic impact of climate change on the coastal and human settlements Sector in Barbados

This study assesses the potential economic impact of climate change on coastal human settlements in the Caribbean, with specific reference to Barbados, and evaluates the costs and benefits of undertaking various adaptation strategies. The aim is to assist Caribbean territories in developing the strategies and capacity needed to deal with the potential impact of severe weather events that are anticipated to occur with increased frequency and intensity as a result of climate change. Some of the key anticipated manifestations of climate change for the Caribbean include elevated air and sea-surface temperatures, sea-level rise, possible changes in extreme events and a reduction in freshwater resources.This research focuses on how human settlements distributed along the coast of Guyana, especially those in low elevation coastal zones (LECZ)are affected by these impacts. Focusing on three potential transmission sources - sea-level rise, stronger storm hazards and increased precipitation – the study considers the vulnerability of populations in the LECZ areas and estimates the overall threat posed by climate change to coastal populations and infrastructure. Vulnerability to climate change (measured as exposed assets) was estimated for four emission scenarios as outlined by the Special Report on Emissions Scenarios (SRES), namely the A1, A2, B1 and B2 scenarios for the period 2010 to 2100 and as detailed by the Intergovernmental Panel on Climate Change (IPCC), using global circulation models (GCM) and storm surge hazard maps.

Evaluation of glycoconjugate antigens as vaccine candidates against group A Streptococcus and human immunodeficiency virus infections

This PhD thesis discusses the rationale for design and use of synthetic oligosaccharides for the development of glycoconjugate vaccines and the role of physicochemical methods in the characterization of these vaccines. The study concerns two infectious diseases that represent a serious problem for the national healthcare programs: human immunodeficiency virus (HIV) and Group A Streptococcus (GAS) infections. Both pathogens possess distinctive carbohydrate structures that have been described as suitable targets for the vaccine design. The Group A Streptococcus cell membrane polysaccharide (GAS-PS) is an attractive vaccine antigen candidate based on its conserved, constant expression pattern and the ability to confer immunoprotection in a relevant mouse model. Analysis of the immunogenic response within at-risk populations suggests an inverse correlation between high anti-GAS-PS antibody titres and GAS infection cases. Recent studies show that a chemically synthesized core polysaccharide-based antigen may represent an antigenic structural determinant of the large polysaccharide. Based on GAS-PS structural analysis, the study evaluates the potential to exploit a synthetic design approach to GAS vaccine development and compares the efficiency of synthetic antigens with the long isolated GAS polysaccharide. Synthetic GAS-PS structural analogues were specifically designed and generated to explore the impact of antigen length and terminal residue composition. For the HIV-1 glycoantigens, the dense glycan shield on the surface of the envelope protein gp120 was chosen as a target. This shield masks conserved protein epitopes and facilitates virus spread via binding to glycan receptors on susceptible host cells. The broadly neutralizing monoclonal antibody 2G12 binds a cluster of high-mannose oligosaccharides on the gp120 subunit of HIV-1 Env protein. This oligomannose epitope has been a subject to the synthetic vaccine development. The cluster nature of the 2G12 epitope suggested that multivalent antigen presentation was important to develop a carbohydrate based vaccine candidate. I describe the development of neoglycoconjugates displaying clustered HIV-1 related oligomannose carbohydrates and their immunogenic properties.

Running Hot and Cold: Economic Liberalization and Foreign Direct Investment in Latin America by Sector

This article examines the effects of market–oriented economic reforms on foreign direct investment (FDI) flows to Latin America from 1985 to 2006. In contrast with most existing scholarship, we disaggregate FDI into its destination in the primary resource, manufacturing, and service sectors allowing us to determine that different kinds of investments exhibit distinct behavior. Notably, manufacturing FDI appears to be erratic; previous investment is not a predictor of current investment. FDI across sectors is associated with varying policy environments, with service and primary resource investment attracted to hosts with policies associated with more stable economic and political contexts. Overall, manufacturing FDI appears to function more like “hot” portfolio investment and is less likely to provide some of the positive spillover effects thought to be associated with more permanent FDI. These findings have an array of implications for economic, development, and industrial policies throughout Latin America and the developing world.

Legality and Human Rights: Administrative Justice in Russia 1862-1917

The question of how far pre-revolutionary Russia was from the ideal of a lawful state has received little academic attention, particularly as relates to the legal regulation of relations between person, society and state within the state administration. Pravilova explored the methods of settling disputes between individuals and the administration, and the emergence of legal controls of the administration, analysed projects for the organisation of administrative justice and studied the particular nature of concepts from Russian administrative justice. The idea of an organisation of special bodies examining complaints by private persons against the actions of officials and state bureaucratic organs first appeared in the early 1860s. In the 1870s-1890s various projects for the reform of administrative justice (reorganisation of the Senate and local administrative institutions) were proposed by the Ministries of Justice and Finance, but none of these was put into practice, largely due to resistance from the bureaucracy. At the same time, however, the rapid development of private enterprise, the activities of the zemstvo and self-government produced new norms and mechanisms for the regulation of authorities and social relations. Despite the lack of institutional conditions, the Senate did consider complaints from private persons against illegal actions by administrative officials, playing a role similar to that of the supreme administrative courts in France and Germany. The spread of concepts of a 'lawful state' aroused support for a system of administrative justice and the establishment of administrative tribunals was seen as a condition of legality and a guarantee of human rights. The government was forced to understand that measures to maintain legality were vital to preserve the stability of the system of state power, but plans for liberal reforms were pushed into the background by constitutional reforms. The idea of guarantees of human rights in relations with the authorities was in contradiction with the idea of the monarchy and it was only when the Provisional Government took power in 1917 that the liberal programme of legal reforms had any chance of being put into practice. A law passed in June 1917 ordained the organisation of local administrative justice bodies, but its implementation was hampered by the war, the shortage of qualified judges and the existing absolute legal illiteracy, and the few administrative courts that were set up were soon abolished by the new Soviet authorities. Pravilova concluded that the establishment of a lawful state in pre-revolutionary Russia was prevented by a number of factors, particularly the autocratic nature of the supreme authority, which was incompatible with the idea of administrative justice as a guarantee of the rights of citizens in their relations with the state.

GLP-1 receptor expression in human tumors and human normal tissues: potential for in vivo targeting

Peptide hormone receptors overexpressed in human tumors, such as somatostatin receptors, can be used for in vivo targeting for diagnostic and therapeutic purposes. A novel promising candidate in this field is the GLP-1 receptor, which was recently shown to be massively overexpressed in gut and lung neuroendocrine tumors--in particular, in insulinomas. Anticipating a major development of GLP-1 receptor targeting in nuclear medicine, our aim was to evaluate in vitro the GLP-1 receptor expression in a large variety of other tumors and to compare it with that in nonneoplastic tissues. METHODS: The GLP-1 receptor protein expression was qualitatively and quantitatively investigated in a broad spectrum of human tumors (n=419) and nonneoplastic human tissues (n=209) with receptor autoradiography using (125)I-GLP-1(7-36)amide. Pharmacologic competition experiments were performed to provide proof of specificity of the procedure. RESULTS: GLP-1 receptors were expressed in various endocrine tumors, with particularly high amounts in pheochromocytomas, as well as in brain tumors and embryonic tumors but not in carcinomas or lymphomas. In nonneoplastic tissues, GLP-1 receptors were present in generally low amounts in specific tissue compartments of several organs--namely, pancreas, intestine, lung, kidney, breast, and brain; no receptors were identified in lymph nodes, spleen, liver, or the adrenal gland. The rank order of potencies for receptor binding--namely, GLP-1(7-36)amide = exendin-4 >> GLP-2 = glucagon(1-29)--provided proof of specific GLP-1 receptor identification. CONCLUSION: The GLP-1 receptors may represent a novel molecular target for in vivo scintigraphy and targeted radiotherapy for a variety of GLP-1 receptor-expressing tumors. For GLP-1 receptor scintigraphy, a low-background signal can be expected, on the basis of the low receptor expression in the normal tissues surrounding tumors.

Novel functional profiling approach combining reverse phase protein microarrays and human 3-D ex vivo tissue cultures: expression of apoptosis-related proteins in human colon cancer

Cancer is caused by a complex pattern of molecular perturbations. To understand the biology of cancer, it is thus important to look at the activation state of key proteins and signaling networks. The limited amount of available sample material from patients and the complexity of protein expression patterns make the use of traditional protein analysis methods particularly difficult. In addition, the only approach that is currently available for performing functional studies is the use of serial biopsies, which is limited by ethical constraints and patient acceptance. The goal of this work was to establish a 3-D ex vivo culture technique in combination with reverse-phase protein microarrays (RPPM) as a novel experimental tool for use in cancer research. The RPPM platform allows the parallel profiling of large numbers of protein analytes to determine their relative abundance and activation level. Cancer tissue and the respective corresponding normal tissue controls from patients with colorectal cancer were cultured ex vivo. At various time points, the cultured samples were processed into lysates and analyzed on RPPM to assess the expression of carcinoembryonic antigen (CEA) and 24 proteins involved in the regulation of apoptosis. The methodology displayed good robustness and low system noise. As a proof of concept, CEA expression was significantly higher in tumor compared with normal tissue (p<0.0001). The caspase 9 expression signal was lower in tumor tissue than in normal tissue (p<0.001). Cleaved Caspase 8 (p=0.014), Bad (p=0.007), Bim (p=0.007), p73 (p=0.005), PARP (p<0.001), and cleaved PARP (p=0.007) were differentially expressed in normal liver and normal colon tissue. We demonstrate here the feasibility of using RPPM technology with 3-D ex vivo cultured samples. This approach is useful for investigating complex patterns of protein expression and modification over time. It should allow functional proteomics in patient samples with various applications such as pharmacodynamic analyses in drug development.

Small town sustainability: economic, social, and environmental innovation. 2. überarb. Aufl.

In an age where the globalization process is threatening the uniqueness and vitality of small towns, and where most urban planning discourse is directed at topics such as metropol-regions or mega-regions and world cities, the authors here emphasize the need to critically reflect on the potential of small towns. The second edition is expanded to cover the intensive development of small towns in China and Korea. In addition, the authors examine the impact of the economic crisis on small towns and the recent development of the Slow City movement.

Economic benefits and costs of Sustainable Land Management Technologies: An analysis of WOCAT's global data

Perceived profitability is a key factor in explaining farmers' decision to adopt or not adopt sustainable land management (SLM) technologies. Despite this importance, relatively little is known about the economics of SLM. This paper contributes to the literature by analysing data on costs and perceived cost/benefit ratios of SLM technologies. Data are taken from the World Overview of Conservation Approaches and Technologies technology database and cover 363 case studies conducted in a variety of countries between 1990 and 2012. Based on an in-depth descriptive analysis, we determine what costs accrue to local stakeholders and assess perceived short-term and long-term cost/benefit ratios. Our results show that a large majority of the technologies in our sample are perceived as being profitable: 73% were perceived to have a positive or at least neutral cost/benefit ratio in the short term, while 97% were perceived to have a positive or very positive cost/benefit ratio in the long term. An additional empirical analysis confirms that economic factors are key determinants of land users' decisions to adopt or not adopt SLM technologies. We conclude that a wide range of existing SLM practices generate considerable benefits not only for land users, but for other stakeholders as well. High initial investment costs associated with some practices may, however, constitute a barrier to their adoption; short-term support for land users can help to promote these practices where appropriate.

Linking livelihood strategies with a regional level landscape mosaic to explore trade-offs between forest conservation and human wellbeing in a Madagascar biodiversity hotspot

The north-eastern escarpment of Madagascar contains the island’s last remaining large-scale humid forest massifs surrounded by diverse small-scale agricultural mosaics. There is high deforestation mainly caused by shifting cultivation practiced by local land users to produce upland rice for subsistence. Today, large protected areas restrict land users’ access to forests to collect wood and other forest products. Moreover, they are no more able to expand their cultivated land, which leads to shorter shifting cultivation cycles and decreasing plot sizes for irrigated rice and cash crop cultivation. Cash crop production of clove and vanilla is exposed to risks such as extreme inter-annual price fluctuations, pests and cyclones. In the absence of work opportunities, agricultural extension services and micro-finance schemes people are stuck in a poverty trap. New development strategies are needed to mitigate the trade-offs between forest conservation and human well-being. As landscape composition and livelihood strategies vary across the region, these strategies need to be spatially differentiated to avoid implementing generic solutions, which do not fit the local context. However, up to date, little is known about the spatial patterns of shifting cultivation and other land use systems at the regional level. This is mainly due to the high spatial and temporal dynamics inherent to shifting cultivation, which makes it difficult to monitor the dynamics of this land use system with remote sensing methods. Furthermore, knowledge about land users’ livelihood strategies and the risks and opportunities they face stems from very few local case studies. To overcome this challenge, firstly, we used remote sensing data and a landscape mosaic approach to delineate the main landscape types at the regional level. Secondly, we developed a land user typology based on socio-ecological data from household surveys in 45 villages spread throughout the region. Combining the land user typology with the landscape mosaic map allowed us to reveal spatial patterns of the interaction between landscapes and people and to better understand the trade-offs between forest conservation and local wellbeing. While shifting cultivation systems are being transformed into more intensive permanent agricultural systems in many countries around the globe, Madagascar seems to be an exception to this trend. Linking land cover information to human-environmental interactions over large areas is crucial to designing policies and to inform decision making for a more sustainable development of this resource-rich but poverty-prone context.
