Relative abundance of dinoflagellate cysts in surface sediments and dinoflagellate counts from three sediment cores from the Atlantic sector of the Southern Ocean

In this study we investigate the potential of organic-walled dinoflagellate cysts (dinocysts) as tools for quantifying past sea-surface temperatures (SST) in the Southern Ocean. For this purpose, a dinocyst reference dataset has been formed, based on 138 surface sediment samples from different circum-Antarctic environments. The dinocyst assemblages of these samples are composed of phototrophic (gonyaulacoid) and heterotrophic (protoperidinioid) species that provide a broad spectrum of palaeoenvironmental information. The relationship between the environmental parameters in the upper water column and the dinocyst distribution patterns of individual species has been established using the statistical method of Canonical Correspondence Analysis (CCA). Among the variables tested, summer SST appeared to correspond to the maximum variance represented in the dataset. To establish quantitative summer SST reconstructions, a Modern Analogue Technique (MAT) has been performed on data from three Late Quaternary dinocyst records recovered from locations adjacent to prominent oceanic fronts in the Atlantic sector of the Southern Ocean. These dinocyst time series exhibit periodic changes in the dinocyst assemblage during the last two glacial/interglacial-cycles. During glacial conditions the relative abundance of protoperidinioid cysts was highest, whereas interglacial conditions are characterised by generally lower cyst concentrations and increased relative abundance of gonyaulacoid cysts. The MAT palaeotemperature estimates show trends in summer SST changes following the global oxygen isotope signal and a strong correlation with past temperatures of the last 140,000 years based on other proxies. However, by comparing the dinocyst results to quantitative estimates of summer SSTs based on diatoms, radiolarians and foraminifer-derived stable isotope records it can be shown that in several core intervals the dinocyst-based summer SSTs appeared to be extremely high. In these intervals the dinocyst record seems to be highly influenced by selective degradation, leading to unusual temperature ranges and to unrealistic palaeotemperatures. We used the selective degradation index (kt-index) to determine those intervals that have been biased by selective degradation in order to correct the palaeotemperature estimates. We show that after correction the dinocyst based SSTs correspond reasonably well with other palaeotemperature estimates for this region, supporting the great potential of dinoflagellate cysts as a basis for quantitative palaeoenvironmental studies.

Fearonomics and the Role of Nigeria's Private Sector in the Nigerian Ebola Response

Background: Outbreaks of infectious diseases such as Ebola have dramatic economic impacts on affected nations due to significant direct costs and indirect costs, as well as increased expenditure by the government to meet the health and security crisis. Despite its dense population, Nigeria was able to contain the outbreak swiftly and was declared Ebola free on 13th October 2014. Although Nigeria’s Ebola containment success was multifaceted, the private sector played a key role in Nigeria’s fight against Ebola. An epidemic of a disease like Ebola, not only consumes health resources but also detrimentally disrupts trade and travel to impact both public and private sector resulting in the ‘fearonomic’ effect of the contagion. In this thesis, I have defined ‘fearonomics’ or the ‘fearonomic effects’ of a disease as the intangible and intangible economic effects of both informed and misinformed aversion behavior exhibited by individuals, organizations, or countries during an outbreak. During an infectious disease outbreak, there is a significant potential for public-private sector collaborations that can help offset some of the government’s cost of controlling the epidemic.

Objective: The main objective of this study is to understand the ‘fearonomics’ of Ebola in Nigeria and to evaluate the role of the key private sector stakeholders in Nigeria’s Ebola response.

Methods: This retrospective qualitative study was conducted in Nigeria and utilizes grounded theory to look across different economic sectors in Nigeria to understand the impact of Ebola on Nigeria’s private sector and how it dealt with the various challenges posed by the disease and its ‘fearonomic effects'.

Results: Due to swift containment of Ebola in Nigeria, the economic impact of the disease was limited especially in comparison to the other Ebola-infected countries such as Liberia, Sierra Leone, and Guinea. However, the 2014 Ebola outbreak had more than a just direct impact on the country’s economy and despite the swift containment, no economic sector was immune to the disease’s fearonomic impact. The potential scale of the fearonomic impact of a disease like Ebola was one of the key motivators for the private sector engagement in the Ebola response.

The private sector in Nigeria played an essential role in facilitating the country’s response to Ebola. The private sector not only provided in-cash donations but significant in-kind support to both the Federal and State governments during the outbreak. Swift establishment of an Ebola Emergency Operation Centre (EEOC) was essential to the country’s response and was greatly facilitated by the private sector, showcasing the crucial role of private sector in the initial phase of an outbreak. The private sector contributed to Nigeria’s fight against Ebola not only by donating material assets but by continuing operations and partaking in knowledge sharing and advocacy. Some sector such as the private health sector, telecom sector, financial sector, oil and gas sector played a unique role in orchestrating the Nigerian Ebola response and were among the first movers during the outbreak.

This paper utilizes the lessons from Nigeria’s containment of Ebola to highlight the potential of public-private partnerships in preparedness, response, and recovery during an outbreak.

Integrated Construction Project Delivery System in the U.S. Public Sector: An Information Modeling Framework

Integrated project delivery (IPD) method has recently emerged as an alternative to traditional delivery methods. It has the potential to overcome inefficiencies of traditional delivery methods by enhancing collaboration among project participants. Information and communication technology (ICT) facilitates IPD by effective management, processing and communication of information within and among organizations. While the benefits of IPD, and the role of ICT in realizing them, have been generally acknowledged, the US public construction sector is very slow in adopting IPD. The reasons are - lack of experience and inadequate understanding of IPD in public owner as confirmed by the results of the questionnaire survey conducted under this research study. The public construction sector should be aware of the value of IPD and should know the essentials for effective implementation of IPD principles - especially, they should be cognizant of the opportunities offered by advancements in ICT to realize this. In order to address the need an IPD Readiness Assessment Model (IPD-RAM) was developed in this research study. The model was designed with a goal to determine IPD readiness of a public owner organization considering selected IPD principles, and ICT levels, at which project functions were carried out. Subsequent analysis led to identification of possible improvements in ICTs that have the potential to increase IPD readiness scores. Termed as the gap identification, this process was used to formulate improvement strategies. The model had been applied to six Florida International University (FIU) construction projects (case studies). The results showed that the IPD readiness of the organization was considerably low and several project functions can be improved by using higher and/or advanced level ICT tools and methods. Feedbacks from a focus group comprised of FIU officials and an independent group of experts had been received at various stages of this research and had been utilized during development and implementation of the model. Focus group input was also helpful for validation of the model and its results. It was hoped that the model developed would be useful to construction owner organizations in order to assess their IPD readiness and to identify appropriate ICT improvement strategies.

Terrigenous input and marine productivity for the Pacific sector of the Southern Ocean based on lipid biomarkers

In this study, we present a new multiproxy data set of terrigenous input, marine productivity and sea surface temperature (SST) from 52 surface sediment samples collected along E-W transects in the Pacific sector of the Southern Ocean. Allochtonous terrigenous input was characterized by the distribution of plant wax n-alkanes and soil-derived branched glycerol dialkyl glycerol tetraethers (brGDGTs). 230Th-normalized burial rates of both compound groups were highest close to the potential sources in Australia and New Zealand and are strongly related to lithogenic contents, indicating common sources and transport. Detection of both long-chain n-alkanes and brGDGTs at the most remote sites in the open ocean strongly suggests a primarily eolian transport mechanism to at least 110°W, i.e. by prevailing westerly winds. Two independent organic SST proxies were used, the UK'37 based on long-chain alkenones, and the TEX86 based on isoprenoid GDGTs. Both, UK'37 and TEX86 indices show robust relationships with temperature over a temperature range between 0.5 and 20°C, likely implying different seasonal and regional imprints on the temperature signal. While alkenone-based temperature estimates reliably reflect modern SST even at the low temperature end, large temperature residuals are observed for the polar ocean using the TEX86 index. 230Th-normalized burial rates of alkenones are highest close to the Subtropical Front and are positively related to lithogenic fluxes throughout the study area. In contrast, highest isoGDGT burial south of the Antarctic Polar Front is not related with dust flux but may be largely controlled by diatom blooms, and thus high opal fluxes during austral summer.

Adaptación del sector turístico al cambio climático en España. La importancia de las acciones a escala local y en empresas turísticas

El 5º Informe del IPCC (Panel Intergubernamental de Cambio Climático, 2014) señala que el turismo será una de las actividades económicas que mayores efectos negativos experimentará en las próximas décadas debido al calentamiento térmico del planeta. En España, el turismo es una fuente principal de ingresos y de creación de puestos de trabajo en su economía. De ahí que sea necesaria la puesta en marcha de medidas de adaptación a la nueva realidad climática que, en nuestro país, va a suponer cambios en el confort climático de los destinos e incremento de extremos atmosféricos. Frente a los planes de adaptación al cambio climático en la actividad turística, elaborados por los gobiernos estatal y regional, que apenas se han desarrollado en España, la escala local muestra interesantes ejemplos de acciones de adaptación al cambio climático, desarrolladas tanto por los municipios (energía, transporte, vivienda, planificación urbanística) como por la propia empresa turística (hoteles, campings, apartamentos). Medidas de ahorro de agua y luz, fomento del transporte público y de las energías limpias, creación de zonas verdes urbanas y adaptación a los extremos atmosféricos destacan como acciones de mitigación del cambio climático en los destinos turísticos principales de nuestro país.

Exploring the potential of cassava in promoting agricultural growth in Nigeria

Cassava is one of the major food crops in Nigeria, with multiple uses from human consumption to industrial applications. This study explores the potential of cassava in Nigerian agriculture based on a review of cassava development policies; performs a trend analysis of the cultivation area, production, productivity, and real price of cassava and other competing crops for the period 1961–2013; identifies the sources of growth in production; and examines the production constraints at the local level based on a survey of 315 farmers/processors and 105 marketers from Delta State. The results revealed that several policies and programmes were implemented to develop the cassava sector with mixed outcomes. Although cassava productivity grew at 1.5% per annum (p.a.) during the post-structural adjustment programme period (1993–2013), its real price declined at a rate of 3.5% p.a. The effect of yield is the main source of growth in production, contributing 76.4% of the total growth followed by the area effect (28.2%). The cassava sector is constrained by inadequate market infrastructure, processing facilities, and lack of information and unstable prices at the local level. The widespread diffusion of improved tropical manioc selection technologies and investments in market and marketing infrastructure, processing technologies, irrigation/water provision and information dissemination are recommended to enhance the potential of the cassava sector to support agricultural growth in Nigeria.

Analysis of the Market Potential of Syrian Organic Fruit and Vegetables for Exports to Germany

Syria has been a major producer and exporter of fresh fruit and vegetables (FFV) in the Arabic region. Prior to 2011, Syrian FFV were mainly exported to the neighbouring countries, the Gulf States and Northern Africa as well as to Eastern European countries. Although the EU is potentially one of the most profitable markets of high quality FFV (such as organic ones) in the world, Syrian exports of FFV to Western European countries like Germany have been small. It could be a lucrative opportunity for Syrian growers and exporters of FFV to export organic products to markets such as Germany, where national production is limited to a few months due to climatic conditions. Yet, the organic sector in Syria is comparatively young and only a very small area of FFV is certified according to EU organic regulations. Up to the author’s knowledge, little was known about Syrian farmers’ attitudes towards organic FFV production. There was also no study so far that explored and analysed the determining factors for organic FFV adoption among Syrian farmers as well as the exports of these products to the EU markets. The overarching aim of the present dissertation focused on exploring and identifying the market potential of Syrian exports of organic FFV to Germany. The dissertation was therefore concerned with three main objectives: (i) to explore if German importers and wholesalers of organic FFV see market opportunities for Syrian organic products and what requirements in terms of quality and quantity they have, (ii) to determine the obstacles Syrian producers and exporters face when exporting agricultural products to Germany, and (iii) to investigate whether Syrian farmers of FFV can imagine converting their farms to organic production as well as the underlying reasons why they do so or not. A twofold methodological approach with expert interviews and a farmer survey were used in this dissertation to address the abovementioned objectives. While expert interviews were conducted with German and Syrian wholesalers of (organic) FFV in 2011 (9 interviews each), the farmer survey was administrated with 266 Syrian farmers of FFV in the main region for the production of FFV (i.e. the coastal region) from November 2012 till May 2013. For modelling farmers’ decisions to adopt organic farming, the Theory of Planned Behaviour as theoretical framework and Partial Least Squares Structural Equation Modelling as the main method for data analysis were used in this study. The findings of this dissertation yield implications for the different stakeholders (governmental institutions and NGOs, farmers, exporters, wholesalers, etc.) who are interested in prompting the Syrian export of organic products. Based on the empirical results and a literature review, an action plan to promote Syrian production and export of organic products was developed which can help in the post-war period in Syria at improving the organic sector.

Review into the Proposed Registration of Teachers and Others who Support Learning in the Independent Sector with the Education Workforce Council

During the passage of the Education (Wales) Bill, Assembly Members called for parity in the way the behaviour of practitioners within maintained schools and the independent sector are regulated. This study was therefore commissioned to gather the views of groups and individuals who work in the education sector in Wales, on whether: i) there should be a requirement for practitioners (both teaching and learning support staff) within independent schools and private FE institutions to register with the Council ii) employers should be legally required to refer cases of unacceptable professional conduct and serious professional incompetence to the Council It was also intended, through this process, to gather views on the potential implications associated with any such registration so that the resulting impact could be identified. The individuals and organisations consulted included head teachers, college principals, governing bodies, teaching staff, learning support staff, trade unions, registration bodies, independent sector representative bodies, inspectorates and teaching councils. Consultations took place between August and November 2015, with data gathered through an online survey, face-to-face interviews, telephone interviews and via email.

FRESH: A Food-service Sustainability Rating for Hospitality Sector Events

This report presents a metric called FRESH (for Foodservice Impact Rating for Environmentally Sustainable Hospitality Events). FRESH can be used to evaluate the performance of any foodservice meal period or event in the hospitality sector with regards to its sustainability, based on seven measurements. These measures are: a (post-consumer) food-waste indicator, a no-show indicator (when unexpectedly few people show up), an over-show measure (when too many people show up), a planning indicator (measuring intentional overproduction), a portion-size indicator (measuring per-guest consumption against expectations), an economies of scale indicator, and a post-event indicator (which depends on disposal approaches). FRESH can help managers, authorities, and potential guests evaluate the sustainability of food production in any establishment.

Abordagem quantitativa do coolhunting ao sector da iluminação

Vivemos um momento de crise, com profundas mudanças globais, a nível político, económico-social e tecnológico, que afetam todos os setores de atividade de forma transversal. A iluminação não está de forma alguma imune a estas alterações. A sobrevivência das empresas requer uma atenção permanente às mudanças do mercado. As formas tradicionais de olhar os mercados e os consumidores, podem tornar-se insuficientes face à rapidez com que as mudanças ocorrem. Algumas metodologias heterodoxas de abordagem ao mercado, como é o caso do coolhunting, começam a ser olhadas de outra forma. Uma das limitações apresentadas na literatura relativamente ao coolhunting é o peso da intuição ou de outras metodologias subjetivas nos resultados obtidos. Numa altura de escassez de recursos, poderá ser problemático para um empresário apostar recursos sem poder contar com números na tomada de decisão, mas apenas em imagens e conceitos. Partindo dos resultados qualitativos de um relatório de coolhunting, este Projeto de Mestrado propõe-se criar e testar uma metodologia que seja capaz de fazer uma análise quantitativa desses resultados de forma que seja possível responder à questão: num determinado mercado que conceitos-chave poderão ter um maior potencial de difusão? Um conjunto de países, de entre os chamados BRIC e os PALOP, foram escolhidos para testar a metodologia. Foi assim possível obter valores em forma de índice comparativo desse potencial de difusão. A metodologia utilizada tem ainda um grande potencial de aperfeiçoamento. Na parte final é apresentada um conjunto de pistas com este objetivo.

Potential of incorporating ocean currents in fishing vessels

The fishing sector has been suffering a strong setback, with reduction in fishing stocks and more recently with the reduction of the fishing fleet. One of the most important factors for this decrease, is related to the continuous difficulty to find fish with quality and quantity, allowing the sector work constantly all year long. However other factors are affecting negatively the fishing sector, in particular the huge maintenance costs of the ships and the high diary costs that are necessary for daily work of each vessel. One of the main costs associated with daily work, is the fuel consumption. As an example, one boat with 30 meters working around 17 hours every day, consumes 2500 liters of fuel/day. This value is very high taking into account the productivity of the sector. Supporting this premise was developed a project with the aim of reducing fuel consumption in fishing vessels. The project calls “ShipTrack” and aims the use of forecasts of ocean currents in the routes of the ships. The objective involves the use of ocean currents in favor, and avoiding ocean currents against, taking into account the course of the ship, in order to reduce fuel consumption and increase the ship speed. The methodology used underwent the creation of specific Software, in order to optimize routes, taking into account the forecasts of the ocean currents. These forecasts are performed using numerical modelling, methodology that become more and more important in all communities, because through the modeling, it can be analyzed, verified and predicted important phenomena to all the terrestrial ecosystem. The objective was the creation of Software, however its development was not completed, so it was necessary a new approach in order to verify the influence of the ocean currents in the navigation of the fishing ship "Cruz de Malta". In this new approach, and during the various ship routes it was gathering a constant information about the instant speed, instantaneous fuel consumption, the state of the ocean currents along the course of the ship, among other factors. After 4 sea travels and many routes analyzed, it was possible to verify the influence of the ocean currents in the Ship speed and in fuel consumption. For example, in many stages of the sea travels it was possible to verify an increase in speed in zones where the ocean currents are in favor to the ships movements. This incorporation of new data inside the fishing industry, was seen positively by his players, which encourages new developments in this industry.

CSR Reporting in the Finnish Banking Sector – Status and Recent Development

This thesis reviews the development of CSR reporting in the Finnish banking sector. This was achieved by analyzing the content of specific CSR reports published by three banks during years 2012-2014. The banks selected represent the three largest banks operating in Finland according to their market share, constituting approximately 70 percent of the total perceived market share. The purpose of the analysis is to establish a clear descriptive overview of the status of CSR reporting and how it has thematically developed over the years. The research was conducted with the qualitative content analysis method. By analyzing the contents of the CSR reports it was found that CSR reporting is understood in 3 different themes that reflect the general CSR theory: economic, social and environmental responsibility. The following research focused on analyzing these three core themes separately during years 2012-2014 in order to find specific tendencies in the development of CSR reporting. The results confirm that CSR reporting is developing in the Finnish banking sector. Reporting about economic responsibility is based on core financial performance reporting, and it’s mainly developing in the assessment of the global recession and how the potential fiscal reforms affect to the bank sector’s performance. Economic responsibility is also being understood and reported as a wider concept, including intertwined and shared meanings with the other responsibility reporting themes. The research also suggests that banks value social responsibility reporting increasingly each year. Environmental responsibility reporting is the most standardized form of reporting, however, the reporting development includes the increased use of digitalization as source of lessening the environmental impact.

Attitudes of Future Tourism Sector Employees Towards Organise Accessible Tourism

The aim of this paper is to show a theoretical approach to the evolution of concepts perceiving disability, taking into account the medical, social, and geographical models, as the basis for the development of principles concerning the organisation of accessible tourism for people with disabilities (PwD). The main research objective was to identify the current attitudes of future, potential employees in the tourism (tourism and recreation students at the time of the study) towards accessible tourism. The study was based on surveys performed in May 2013 at the Adam Mickiewicz University in Poznań (UAM, Poland) and the State University in Irkutsk (ИГУ, Russia), a total sample of 216 people. The main section of the survey contained four questions regarding issues such as: optimal ways to organise tourism products for people with a disability; attitudes towards spending leisure time together with people with a disability; and specific requirements concerning the introduction of various types of improvements in tourism products aimed at people with a disability. In both cases, the results revealed that future tourism employees hold attitudes which are prevailingly open and positive towards the needs of tourists with disabilities. However, the hypothesis that the main factor influencing a reluctance to enter into contact with PwD is a lack of experience in this area, resulting in insufficient knowledge of what conditions the behaviour of PwD was also confirmed. This is a highly significant conclusion which should consider if mandatory educational programmes in the field of tourism and recreation studies are to be improved.

A house, not a home? Examining the use of the private rented sector to resolve homelessness in Scotland

Changes to homelessness legislation in post-devolution Scotland have resulted in an expansion of rights for homeless households seeking formal assistance from local authorities. These changes have led to Scotland’s homelessness arrangements being considered among the most progressive in Europe. In recent years, however, the Scottish Government has increasingly promoted homelessness prevention and Housing Options approaches as a means by which homelessness might be avoided or resolved without recourse to statutory rights. As part of that, they have promoted greater use of the private rented sector (PRS) as a key housing option, with the potential to meet the needs of homeless households. The arguments made to support use of the PRS have much in common with arguments for privatisation in other areas of social policy, notably greater choice for the individual promoting better welfare outcomes, and competition among providers encouraging improvements in quality of service provision. Critics have argued that such benefits may not be realised and that, on the contrary, privatisation may lead to exclusion or act to worsen households’ outcomes. This thesis considers the extent to which the PRS has been utilised in Scotland to accommodate homeless households, and the consequences of this for their welfare. The thesis uses a combination of quantitative and qualitative methods. To examine trends in the use of the PRS, it presents quantitative analysis of the data on the operation of the statutory system and Housing Options arrangements, and of data from a survey of local authority homelessness strategy officers. To examine the consequences of this for homeless households, the thesis uses qualitative research involving face-to-face interviews with 35 homeless households across three local authority areas. This research considers the extent to which households’ experiences of homelessness, housing need and the PRS reflect the arguments presented in the literature, and how settled accommodation has impacted on households’ ability to participate fully in society. The research found an increasing but still limited role for the PRS in resolving statutory homelessness in Scotland, with indications that the PRS is being increasingly used as part of the Housing Options approach and as a means of resolving homelessness outside the statutory system. The PRS is being utilised to varying degrees across different local authority areas, and a variety of methods are being used to do so. While local authorities saw clear advantages to making greater use of the sector, a number of significant barriers including affordability, available stock and landlord preferences - made this difficult in practice. Research with previously homeless households in the PRS similarly found broadly positive experiences and views of the sector, particularly with regard to enabling households to access good quality accommodation in desirable areas of their choosing, with many households highlighting improvements relating to social inclusion and participation. Nevertheless, concerns around the security of tenure offered by the sector, repairs, service standards and unequal power relations between landlord and tenant persisted. As such, homeless households frequently expressed their decision to enter the sector in terms of a trade-off between choice and security.

Intelligent pipeline control - a simulation study in the automotive sector

Automotive producers are aiming to make their order fulfilment processes more flexible. Opening the pipeline of planned products for dynamic allocation to dealers/ customers is a significant step to be more flexible but the behaviour of such Virtual-Build-To-Order systems are complex to predict and their performance varies significantly as product variety levels change. This study investigates the potential for intelligent control of the pipeline feed, taking into account the current status of inventory (level and mix) and of the volume and mix of unsold products in the planning pipeline, as well as the demand profile. Five ‘intelligent’ methods for selecting the next product to be planned into the production pipeline are analysed using a discrete event simulation model and compared to the unintelligent random feed. The methods are tested under two conditions, firstly when customers must be fulfilled with the exact product they request, and secondly when customers trade-off a shorter waiting time for compromise in specification. The two forms of customer behaviour have a substantial impact on the performance of the methods and there are also significant differences between the methods themselves. When the producer has an accurate model of customer demand, methods that attempt to harmonise the mix in the system to the demand distribution are superior.
