Spatial structures of manufacturing clusters in Cambodia, Lao People's Democratic Republic, and Thailand

Examining the spatial structure of clusters is essential for deriving regional development policy implications. In this study, we identify the manufacturing clusters in Cambodia, the Lao People's Democratic Republic, and Thailand, using two indices—global extent (GE) and local density (LD)—as proposed by Mori and Smith (2013). We also analyze four different combinations of these indices to highlight the spatial structures of industrial agglomerations. Since industrial clusters often spread over administrative boundaries, the GE and LD indices—along with cluster mapping—display how the detected clusters fit into specific spatial structures.

Geochemistry of the water column of southern lake Baikal during 1967-2005

At present, when the influence of human economic activity is progressively increasing, significant attention is devoted to the state of water ecosystems. All researchers engaged in these problems agree that the state of the water system (pollution and eutrophication) can only be estimated on the basis of long-term researches. Systemic monitoring (at least once per month) of ionic components (Ca2+, Mg2+, Na+, K+, bicarbonates, sulfates, and chlorides) in unfiltered water of Lake Baikal and its tributaries had been carried out under the supervision of Votintsev since 1947. Based on the analysis of systematic data on trophic components obtained during 1965-2005, we tried to estimate the present-day trophic status of the pelagic zone in the lake, define the trend of long-term changes of trophic components and understand the reasons of the distortion of cyclicity in the development of spring diatom algae, which create a favorable environment in any water basin. It should be noted that the station near Cape Polovinnyi is located 20 km away from the town of Baikal'sk. Wastewaters of the Baikal'sk pulp and paper mill is the main source of dioxins and furans in Baikal. Based on the significant difference between sulfate contents in wastewaters of the plant (>300 mg/l), tributaries of Baikal (7.5 mg/l), and waters in the southern part of the lake (3.9 mg/l), we defined the following periods: (i) period of natural seasonal patterns until 1967-1968 (prior to putting the Baikal'sk Mill into operation; (ii) period of weak anthropogenic pollution (1969-1985); and (iii) period of strong anthropogenic pollution since 1986.

The corporate regimen of labour companies in the New Act 44/2015, on 14th October, of labour and investee companies

Act 44/2015, on 14th October, of labour and investee companies, aims to accommodate the different instruments, limits and requirements with which the legal regime of the labour companies is set, to the current economic and legal context where they must develop their economic activity. The purpose of the law is to preserve their special status, while it seeks to modernize its legal structure to ensure the economic solvency of the business plan, without weakening the social profile that is required. The new law includes two organisational figures, ‘labour companies’ and the calling ‘investee companies’, of the last one, only leaving evidence of what is to be understood by them referring its regulation to a subsequent regulatory development. Until the publication of the regulation, our work has focused on the corporate aspect of the labour companies by analysing the modifications made on the typological elements and legal regime of these organisational figures to determine whether the law is the necessary and sufficient instrument to achieve the challenge proposed.

Unstructured grid modelling of offshore wind farm impacts on seasonally stratified shelf seas

Shelf seas comprise approximately 7% of the world’s oceans and host enormous economic activity. Development of energy installations (e.g. Offshore Wind Farms (OWFs), tidal turbines) in response to increased demand for renewable energy requires a careful analysis of potential impacts. Recent remote sensing observations have identified kilometrescale impacts from OWFs. Existing modelling evaluating monopile impacts has fallen into two camps: small-scale models with individually resolved turbines looking at local effects; and large-scale analyses but with sub-grid scale turbine parameterisations. This work straddles both scales through a 3D unstructured grid model (FVCOM): wind turbine monopiles in the eastern Irish Sea are explicitly described in the grid whilst the overall grid domain covers the south-western UK shelf. Localised regions of decreased velocity extend up to 250 times the monopile diameter away from the monopile. Shelf-wide, the amplitude of the M2 tidal constituent increases by up to 7%. The turbines enhance localised vertical mixing which decreases seasonal stratification. The spatial extent of this extends well beyond the turbines into the surrounding seas. With significant expansion of OWFs on continental shelves, this work highlights the importance of how OWFs may impact coastal (e.g. increased flooding risk) and offshore (e.g. stratification and nutrient cycling) areas.

Garden Cities: A flawed model for Ecological Urbanism?

Since the beginning of the 20th century, the Garden City model has been a predominant theory emerging from Ecological Urbanism. In his book Howard observed the disastrous effects of rapid urbanization and as a response, proposed the Garden City. Although Howard’s proposal was first published in the late 1800’s, the clear imbalance that Howard aimed to address is still prevalent in the UK today. Each year, the UK wastes nearly 15 million tons of food, despite this an estimated 500,000 people in the UK go without sufficient access to food. While the urban population is rapidly increasing and cities are becoming hubs of economic activity, producing wealth and improving education and access to markets, it is within these cities that the imbalance is most evident, with a significant proportion of the world’s population with unmet needs living in urban areas. Despite Howard’s model being a response to 17th century London, many still consider the Garden City model to be an effective solution for the 21st century. In his book, Howard details the metrics required for the design of a Garden City. This paper will discuss how, by using this methodology and comparing it with more recent studies by Cornell University and Matthew Wheeland (Pure Energies); it is possible to test the validity of Howard’s proposal to establish whether the Garden City model is a viable solution to the increasing pressures of urbanization.
This paper outlines how the analysis of Howard’s proposal has shown the model to be flawed, incapable of producing enough food to sustain the proposed 32,000 population, with a capacity to produce only 23% of the food required to meet the current average UK consumption rate. Beyond the limited productive capacity of Howard’s model, the design itself does little to increase local resilience or the ecological base. This paper will also discuss how a greater understanding of the
Land-share requirements enables the design of a new urban model, building on the foundations initially laid out by Howard and combining a number of other theories to produce a more resilient and efficient model of ecological urbanism.

Achieving forms of sustainable and competitive tourism in coastal areas: the case of Baixo Vouga

Tourism has become the world’s largest industry, and has overcome economic sectors such as oil production and car manufacturing. It is foreseen that tourism will continue to expand in the future and will spread all around the world. In Europe, the tourism sector is made of 440 million international arrivals that are responsible for accounting about 10% of European GDP and generating 20 million jobs. Coastal destinations are major tourist destinations. This is due to their physical attractiveness, beautiful landscapes, and fine open space for leisure activities. Nevertheless, sun-sea-sand tourism depends very much on the environment. In this way, coastal destination ought to be properly planned so they do not exceed the limits of acceptable change (LAC) of the ecosystems, and keep their attractiveness. Being an economic activity, it is essential that coastal tourism is competitive, and show capacity to attracting new and enlarged markets. Coastal destinations should diversify its products and services, smooth seasonality and become more competitive. Diversification should create more growth and employment, and also reduce environmental, economic and social impact caused by the concentration of tourism activity in a few months of the year and the use of only the beach resource. This paper aims at analyzing the application of the competitiveness concept to tourism in coastal areas (Ria de Aveiro region, Central Portugal), and draws attention to the principle of environmental, economical and social sustainability.

Impactos sociais da atividade turística: um estudo de caso em Tibau do Sul/RN

This study has been presented for the Master in business of the Universidade Federal do Rio Grande do Norte, the objectives are evaluate the social impacts of the tourism in the community of Tibau do Sul in the state of Rio Grande do Norte. The research is a study of case and the analysis is qualitative and quantitative. The tourism is considerate for many people as an important source of richness, job and an important economic activity. However, for being an activity that involves as main element people, It can cause impacts, could these are beneficial or malign. To evaluate the community's perception about these impacts, it was applied a questionnaire returned to the perceptions of them about the next social indicators: health, job, security, education and life quality. Considering the advent of the tourist activity in a period fifteen year. Through the research could conclude that, of general form the population realizes the changes occurred in the municipal district of positive way. Except for some indicators that receive negative evaluation

O city marketing em Natal/RN e a construção da imagem da cidade

The growing importance of tourism in overall economic activity worldwide has favored the intensification of competition among cities that seek to create environments attractive to tourists and potential investors. It has been common practice to import characteristics of the business environment in the public management of cities. The city marketing is a key tool used by public leaders to promote a linkage between the tourism image and urban image and involves, in addition to promoting the image of the city, the planning of interventions in urban space, trying to formulate a positive image of the city able to facilitate the deployment of capital. This research seeks to understand the nature of city marketing as part of contemporary urban management and analyzes how is its application in decisions concerning the promotion of tourism in Natal/RN. The approach of this research is qualitative, exploratory and descriptive, in which respondents were the main leaders of two of the official tourism site, the Empresa Potiguar de Promoção Turística and the Secretaria Municipal de Turismo e Desenvolvimento Econômico. It was found that there is a strong articulation of public power with private enterprise in the design and conduct of the actions of urban marketing, that from the survey data show that the behavior of target markets provide guidelines for taking strategic decisions relating to tourism. Sun and sea are some key elements explored to form the image of Natal and to authorize the sale of the city as a tropical paradise. However, there is an increase in the diversification of tourism products, seeking to increase flow to the segments of ecotourism, adventure, business and culture. It s also growing the use of local culture as a tourism product, however, the cultural representation focuses on superficial values and does not bring to light the social and historical richness that the city has. Public authorities use the city marketing strategies as a means able to maximize the attractiveness of Natal urban space to investors, business groups and tourists. It can be observed that urban managers seek solutions that can continuously increase the tours, which often manifests in interventions that focus the tourist areas of the city, in oposition of those who do not contribute to a positive reading of the city, which ultimately generate the worsening of spacial and social inequalities

Metodología para la mitigación de los errores en los procesos de construcción de proyectos de edificaciones

En nuestro país una de las actividades de mayor actividad económica, generadora de empleo directo e indirecto y de alta dinámica e inversión en la industria de la construcción, se hace necesario la implementación de un control durante cada una de las etapas del proyecto, donde las personas que integran el equipo de trabajo (Administración-Construcción-Interventoría) tengan definidos sus alcances y responsabilidades durante la ejecución de los proyectos y en sus diferentes etapas. Es un estudio para 20 edificaciones en diferentes sectores del Valle de Aburrá, con el fin de implementar una metodología que ayude a minimizar los errores en cualquier etapa del proyecto, en otras palabras se basa en detectar de manera inmediata o a corto plazo cualquier error o anomalía que se presente y como consecuencia pueda generar resultados nefastos en pérdidas humanas y económicas. Finalmente se concluye que la aplicación e implementación de esta metodología deja abierta las puertas para continuar con estos estudios y lograr en un futuro la optimización para minimizar y mitigar al máximo los diferentes errores constructivos.

O terciário (re) desenhando a periferia: a região administrativa norte de Natal/RN, na última década do século XX, servicializada na Av. Dr. João Medeiros Filho

The tertiary sector has been (re)defining and (re)qualifying, in an impacting way, the urban spaces in the cities, introducing new elements for the discussion of the relationship center/periphery. In Natal, as an inducing economic activity of its development, it conforms to the new needs of the capital, expanding, being materialized through several processes and spatial forms. We aim at analyzing one of those processes, which has taken its Northern Administrative Area to (re)define the design of its urban space, through the actions developed by the agents involved with the spatialization of the tertiary activities, at the same time as it redimensions its role as a periphery of Natal, contributing to the study of the recent and growing transformations of the Brazilian capitals. The studied district corresponds to 39.4% of the municipal area and, until recently, was composed by precarious reproduction spaces, unprovided of relevant economical activities. After the boom of the development of extensive housing complexes by SFH/BNH, the area, gradually stopped being a dependent area, and it imposed itself as an economically participant region, with the increase of the trade and services sectors, as well as a favorable place for the appearance of new activities. Its reflexes are noticeable in the achieved spatial configuration. As the main road to induct changes, Dr. João Medeiros Filho Avenue presents these new tendencies in the production of the intraurban space, concentrating the largest goods and services equipments of the area, through investments of the private and public sectors, which guarantee the capital allocation for the construction of a new centrality

A national coastal erosion risk assessment for Scotland

The geography of Scotland, with a highly undulating hinterland, long and indented coastline, together with a large number of islands, means that much social and economic activity is largely located at the coast. The importance of the coast is further highlighted by the large number of ecosystem services derived from the coast. The threat posed by climate change, particularly current and future sea level rise, is of considerable concern and the associated coastal erosion and coastal flooding has the potential to have a substantial effect on the socioeconomic activity of the whole country. Currently, the knowledge base of coastal erosion is poor, which serves to hinder the current and future management of the coast. This research reported here aimed to establish four key aspects of coastal erosion within Scotland: the physical susceptibility of the coast to erosion; the assets exposed to coastal erosion; the vulnerability of communities to coastal erosion; and the coastal erosion risk to those communities. Coastal erosion susceptibility was modelled here within a GIS, using data for ground elevation, rockhead elevation, wave exposure and proximity to the open coast. Combining these data produced the Underlying Physical Susceptibility Model (UPSM), in the form of a 50 m2 raster of national coverage. The Coastal Erosion Susceptibility Model (CESM) was produced with the addition of sediment supply and coastal defence data, which then moderates the outputs of the UPSM. Asset data for dwellings, key assets, transport infrastructure, historic assets, and natural assets were used along with the UPSM and CESM to assess their degree of exposure to coastal erosion. A Coastal Erosion Vulnerability Model (CEVM) was produced using Experian Mosaic Scotland (a geodemographic classification which identifies 44 different social groups within Scotland) to classify populations based upon 11 vulnerability variables. Dwellings were assigned a CESM and CEVM score in order to establish their coastal erosion risk. This research demonstrated that the issue of coastal erosion will impact on a relatively low number of properties compared to those impacted by flooding (both coastal and fluvial) as many dwellings are already protected by coastal defences. There is therefore, a considerable future liability, and great pressure for coastal defences to be maintained and upgraded in their current form. The use of the CEVM is a novel inclusion within a coastal erosion assessment for Scotland. Use of the CEVM established that coastal erosion risk is not distributed equally amongst the Scottish coastal population and highlighted that risk can be reduced by either reducing exposure or reducing vulnerability. Thus far in Scotland, reducing exposure has been the primary management approach, which has a number of implications with regards social justice. This research identified the existing data gaps that should be addressed by future research in order to further improve coastal management in Scotland. Future research should focus on assessing historical coastal change rates on a national scale, improve modelling of national scale wave exposure, enhance the information held about current coastal defences and, determine the direct and indirect economic cost associated with the loss of different asset types. It is also necessary to clarify the social justice implications of using adaptation approaches to manage coastal erosion as well as establishing a method to communicate the susceptibility, exposure, vulnerability and risk aspects whilst minimising the potential negative impacts (e.g. property blight) of releasing such information.

La pêche au calmar à Nhatrang

Squid fishing is a very important economic activity in many far eastern countries. One of the reasons seems to be an easy process for conservation (dried squid) and high demand from the Chinese market.

Working for Families Phase 1 Evaluation 2004-2006 Executive Summary.

This report presents an evaluation of Phase 1 of the Working for Families Fund (WFF) covering 2004-06. WFF was established to invest in new initiatives to improve the employability of parents who have difficulties in participating in the labour market, specifically in employment, education or training. The Fund supported these parents through helping them find sustainable childcare solutions and through providing or accessing other relevant employability-related services. In rural areas, barriers created by poor transport, limited services and the lack of a critical mass of clients were also particularly important. WFF contributes to the Scottish Executive’s Closing the Opportunity Gap approach to tackling poverty and disadvantage, by improving rates of employment and economic activity, and to its commitment to eradicating child poverty within a generation.
