Política exterior de Canadá en el ártico: entre la seguridad nacional y la prosperidad económica (2006-2011)

En el año 2010 el gobierno de Canadá pública su estrategia de política exterior hacia el Ártico, en la cual manifiesta que esta región es una de las principales prioridades del Gobierno de Stephen Harper en materia de política exterior. Así las cosas, a partir de la perspectiva teórica del realismo neoclásico la investigación se enfoca en analizar por qué la seguridad nacional y la prosperidad económica son los principales intereses de este Gobierno en la zona.

Percepción logística empresarial de los sectores productivos agrícola y textil en Colombia

Desde el año 2007 se ha venido presentando un crecimiento progresivo en Colombia, donde la participación del comercio exterior en el PIB (Producto Interno Bruto) ha aumentado, según cifras del Departamento Nacional de Planeación (DNP). En contraste a esto, Colombia últimamente se ha caracterizado por presentar falencias en su desempeño logístico, las cuales se ven reflejadas en el LPI (Logistics Performance Index), una herramienta desarrollada por el Banco Mundial que mide el desempeño de la cadena de suministro de un país. El Gobierno y sus ministerios han velado por mejorar la competitividad del país, y advierten una serie de tratados y acuerdos internacionales que facilitarán el intercambio de productos junto con el fortalecimiento de la industria; a lo cual, las empresas colombianas deberán encaminar sus esfuerzos y al interior de la organización deberán tomar partida en cuanto a la capacitación del personal en temas logísticos, la administración de los costos y la eficiencia en los procesos. Así pues, mediante la realización de un estudio de la percepción que tienen los empresarios actuales en materia de logística, donde se evalúan distintas variables relacionadas con la administración de la cadena de suministro; se podrá entender holísticamente la problemática del sector, específicamente de los sectores agrícola y textil: dos sectores influyentes en el PIB nacional, generadores de empleo y con una gran cantidad de empresas asociadas. Igualmente, proponer medidas de mejora cercanas a la realidad, que contribuyan con el buen desempeño de las empresas en todo el curso de su cadena de suministro, con actividades involucradas como la planeación, las compras, el abastecimiento, las operaciones, la producción, el almacenamiento, los despachos y la distribución. Finalmente, se logrará tener un acercamiento al perfil logístico que deberán tener estas empresas en el marco de la competitividad, contando con herramientas que de una u otra manera permitan a los empresarios la toma de decisiones acertadas en pro de la organización y sus partes interesadas.

Eficiencia de los sistema de salud en los países de América Latina y del Caribe desde el indicador de esperanza de vida al nacer para los años 1990 y 2012 frente al gasto total en salud como porcentaje del producto interno bruto para el año 1995 y 2012 “una oportunidad de brenchmarking para el sistema de protección social colombiano”

Para los países emergentes en América Latina y El Caribe se hace necesario determinar la eficiencia de su sistema de salud para generar beneficios a su población desde el indicador de esperanza de vida al nacer y los recursos que se hacen uso desde Colombia en comparación con sus homólogos. Se evidencia que a pesar de Colombia poseer una economía fuerte durante el análisis de los dos momentos se mantiene en la tendencia general de los demás países y con los mismos resultados del indicador. A su vez se concluye que el momento en que se tomaron las decisiones de cambio del sistema de salud es un factor diferenciador en los resultados obtenidos como fue el caso de Costa Rica identificado con el de mejor desempeño en la relación Indicador de esperanza de vida al nacer y Porcentaje de gasto en salud como parte del Producto interno bruto.

Bayesian density estimation using Skew Student-t-Normal mixtures

We present a Bayesian approach for modeling heterogeneous data and estimate multimodal densities using mixtures of Skew Student-t-Normal distributions [Gomez, H.W., Venegas, O., Bolfarine, H., 2007. Skew-symmetric distributions generated by the distribution function of the normal distribution. Environmetrics 18, 395-407]. A stochastic representation that is useful for implementing a MCMC-type algorithm and results about existence of posterior moments are obtained. Marginal likelihood approximations are obtained, in order to compare mixture models with different number of component densities. Data sets concerning the Gross Domestic Product per capita (Human Development Report) and body mass index (National Health and Nutrition Examination Survey), previously studied in the related literature, are analyzed.

Modeling and forecasting long-term natural gas (NG) consumption in Iran, using particle swarm optimization (PSO)

The gradual changes in the world development have brought energy issues back into high profile. An ongoing challenge for countries around the world is to balance the development gains against its effects on the environment. The energy management is the key factor of any sustainable development program. All the aspects of development in agriculture, power generation, social welfare and industry in Iran are crucially related to the energy and its revenue. Forecasting end-use natural gas consumption is an important Factor for efficient system operation and a basis for planning decisions. In this thesis, particle swarm optimization (PSO) used to forecast long run natural gas consumption in Iran. Gas consumption data in Iran for the previous 34 years is used to predict the consumption for the coming years. Four linear and nonlinear models proposed and six factors such as Gross Domestic Product (GDP), Population, National Income (NI), Temperature, Consumer Price Index (CPI) and yearly Natural Gas (NG) demand investigated.

Is the Genuine Progress Indicator really genuine? Considering well-being impacts of exports and imports

The Genuine Progress Indicator (GPI) is estimated as if nations operate within a closed economy. Therefore, in terms of coverage, the GPI is most analogous to Gross Domestic Product (GDP). Indeed, within the relevant literature, these two indicators are most often contrasted. However, consideration should be given to adapting the GPI, so it has more in common with Gross National Income (GNI). As with GDP, the GPI is concerned only with a particular physical location. Yet, it may be more effective if the GPI was freed from these physical boundaries in a similar manner to GNI. The GPI should be concerned more with the 'ownership' of the costs and benefits associated with economic growth than with the 'location' of those costs and benefits. Those that derive the most benefit from exploitation of the environment are often physically removed from the location of that damage. The GPI does not consider the net consumers of the negative externalities of environmental costs, merely the producers. Currently, however, the structure of the GPI allows a nation to enjoy, without penalty, the benefits of importing goods from countries which bear a disproportionately large cost of environmental degradation. This results in an overstatement of the real progress experienced by the county importing 'dirty goods'. This paper will investigate how certain GPI adjustments may be adapted to overcome this present shortcoming. However, the purpose of this paper is not only to empirically implement this new approach, but also to stimulate debate as to its potential merit.

Comparing Australias genuine progress to its economic growth performance

Australia has recorded consistently strong levels of economic growth in recent times. Under conventional considerations, the well-being experienced by Australians would also be considered to have increased in equal terms over this period. This is because aggregate standard national accounts have from their inception been assigned as proxy measures of well-being both within the economic literature and public debate. However, this approach fails to consider a number of important economic costs and non-welfaristic impacts on well-being associated with a growing economy. As a result, figures such as Gross Domestic Product (GDP) per capita over-estimate well-being. It is possible to adjust these estimates to overcome these limitations. Within this paper, the sustainable well-being of Australia will be reviewed by estimating a Genuine Progress Indicator (GPI) for the period 1986–2003. Policy implications following from this new analysis will also be discussed.

Comparing Victoria's genuine progress with that of the Rest-of-Australia

While a range of exogenous and endogenous factors affect the standard of  living of most Australians in a more-or-less uniform way, the different social and economic-policies of each state government are likely to affect the levels of sustainable well-being experienced across the various states. With this in mind, a Genuine Progress Indicator (GPI) - a newly devised measure of sustainable well-being - is calculated for Victoria and the Rest- of- Australia (Australia minus Victoria) for the period 1986-2003. The GPI takes account of the various costs and benefits of economic activity in order to investigate the impact of a growing state or national economy on sustainable well-being.
By analysing the GPI results and the policies undertaken by the Victorian government, it is possible to determine what the state of Victoria is doing differently to the Rest-of-Australia that might be beneficial or detrimental to sustainable well-being. While our study reveals that Victoria is performing better than the Rest-of-Australia, it also highlights flaws in the policy-making process that have resulted in Victoria's Gross State Product (GSP) overstating its genuine progress.

Challenges facing housing affordability in Beijing in the Twenty-first century

Purpose – The purpose of this paper is analyse to what extent the high price had led to low levels of housing affordability in the period 2002-2006 in Beijing. Due to the importance of housing for local residents and the crucial position that real estate market in the Chinese economy is currently in, research into the housing affordability issues is now essential. It is important to consider the social circumstances that are predominantly related to both the standard of living and the national economy in Beijing.

Design/methodology/approach – The housing price to income ratio (PIR) method and Housing Affordability Index (HAI) model are used to measure housing affordability in Beijing. Then, the reasons for the high housing prices in Beijing are discussed and government homeownership-oriented policies to help citizen on housing issues are examined. Finally, future proposals which can contribute to ease the housing affordability problem are recommended.

Findings – The main findings in this research are that the PIR in the Beijing housing market (based on an average gross floor area of 60?m2) fluctuated between 6.69 and 9.12, respectively, between 2002 and 2006. Over the same period, the HAI was approximately 75 between 2002 and 2004, although decreasing sharply in 2005 (65.78) and 2006 (51.33). It appears that the Chinese government's new housing provision policies may be able to ease this affordability problem, especially with regards to the economic housing scheme.

Originality/value – China has experienced rapid growth in gross domestic product (GDP) with a substantial increase in house prices which have affected housing affordability for typical Beijing households. Since the housing reform in China commenced in 1998, Beijing residents, government officers and academics have been concerned about high housing prices in the city, which is considered beyond the buying capability of the ordinary residents. The results are designed to provide an insight into the level of housing affordability in Beijing and whether a trend exists.

An econometric model of the determinants of private investment and a CGE model of the impact of democracy on investment and economic growth in Fiji

Purpose – The purpose of this paper is to construct an econometric model of the determinants of private investment with a particular focus on the impact of democracy on investment.

Design/methodology/approach – The first step was to econometrically derive the long-run elasticities; then to modify the Fiji computable general equilibrium (CGE) model to incorporate the investment function. Also the econometrically derived long run elasticities in the CGE model were used.

Findings – It was found that democracy has a positive and statistically significant impact on private investment in Fiji. The paper's simulation of Fiji becoming a fully democratic country on investment and other macroeconomic fundamentals, based on a CGE model, reveals that real gross domestic product and real national welfare increase by around 0.01 and 0.05 per cent, respectively; government savings and revenue performance improves; there is a trade balance surplus; and both private consumption and disposable income increase by around 0.05 and 0.12 per cent, respectively.

Originality/value – This is the first study that uses a CGE model to examine the impact of democracy, via investment, on other macroeconomic fundaments. No other study is known to have modelled democracy in a CGE framework.

Use of wild fish and other aquatic organisms as feed in aquaculture; a review of practices and implications in the Asia Pacific

Global and Asian aquaculture have witnessed a ten-fold increase in production from 1980 to 2004. However, the relative percent contribution to production of each of the major commodities has remained almost unchanged. For example, the contribution of freshwater finfish has declined from 71 to 66 percent in Asia but has remained unchanged globally over the last 20 to 30 years. This fact has dictated trends in the use of fish as a feed for cultured stocks. The growth in the sector has gone hand in hand with an increasing dependence on fish as feed, either directly or indirectly. In a number of countries in the Asia-Pacific region, the aquaculture sector has surpassed the capture fisheries sector in its respective contributions to the gross domestic product (GDP). Aquaculture’s increased contribution to national GDPs can be taken as a clear indication of the contribution of the sector to food security and poverty alleviation. The use of finfish and other aquatic organisms as a feed source can be through direct utilization of whole or chopped raw fish in wet form, through fishmeal and fish oil in formulated feeds, and/or as live fish, although the latter is uncommon and the overall amounts used are relatively small. In the first two categories, the fish used are often termed “trash fish/low-value fish”. Although attempts have been made to define this term, all definitions have a certain degree of ambiguity and/or subjectivity. In this regional review, the amount of fish used as feed sources based on the above categories was estimated primarily from the production data, supported by assumptions on the inclusion levels of fishmeal in formulated feeds and observed feed conversion efficiencies for both formulated feeds and for stock fed trash fish/low-value fish directly. A scenario for the use of fish as feed was developed by starting from the levels of aquaculture production recorded in 2004 and assuming increases in production volumes of 10, 15 and 20 percent by 2010, respectively, for the three trajectories. In parallel, the pattern of wild fish use as feed was projected to change as fish and shrimp farmers increasingly replace farmmade feeds by incorporating trash fish/low-value fish with manufactured feeds that include fishmeal. Also, the fishmeal inclusion rates in manufactured feeds are falling slowly, and this has been incorporated into the projections. The regional review also deals with the production of fishmeal using trash fish/low-value fish in the Asia-Pacific region. Regional fishmeal production as a whole is relatively low when compared with that of major fishmeal-producing countries such as Chile, Iceland and Norway, amounting to approximately 1 million tonnes per year. However, there is a trend towards increasing the use of fish industry waste, such as from the tuna canning industry in Thailand. The fishmeal produced in the region is priced considerably lower than globally traded fishmeal, but its quality is poorer. Total fishmeal use in Asian aquaculture in 2004 was estimated as 2 388 million tonnes, the highest proportion of this being used for crustacean aquaculture (1 418 million tonnes). Based on growth predictions (to year 2010) in the sector and improvements to feed quality and management, it is expected that the quantity of fishmeal used in Asian aquaculture will be slightly less than at present. An estimated 240 000 tonnes of fish oil is used in Asian aquaculture, principally in shrimp feeds. Based on production estimates of commodities in 2004 that rely on trash fish/low-value fish as the main feed source, this regional review suggests that Asian aquaculture currently uses between 2 465 and 3 882 million tonnes, an amount that is predicted to decrease to between 1.890 and 2 795 million tonnes by 2010. The use of trash fish/low-value fish and fishmeal by the aquaculture sector has been repeatedly adjudicated as a non-sustainable practice, and globally the sector is seeking to reduce its dependence on fish as feed through improved feed management practices and development of better quality feeds and feed formulations using alternative ingredients. Over the next few years, decreases in the use of trash fish/low-value fish are also expected to be achieved through better conversion of raw materials into fishmeal and fish oil during the reduction processes. The “way forward” in addressing the issue of the use of fish as feed in aquaculture in the Asia-Pacific region includes the need for a concerted regional research thrust to reduce the use of fish as feed sources in aquaculture, as has been achieved in the animal husbandry sector. Secondly, there is a need to increase farmer awareness on the use of trash fish as feed. This is achievable, considering the similar progress that has been made by the region’s shrimp farming sector, which almost exclusively involves small-scale practitioners who are often clustered in a given locality. The analysis also suggests that the use of trash fish/low-value fish in aquaculture may be compatible with improving food security and alleviating poverty. In Asia, trash fish/low-value fish is mostly landed in areas where there are other suitable fish commodities for human consumption. To make the trash fish/low-value fish suitable and available for human consumption would involve some degree of value-adding and transportation costs, which are likely to increase the price to beyond the means of the consumer, particularly in remote rural areas. Under such a scenario, the direct or indirect use of this perishable resource as a feed source to produce a consumable commodity appears to make economic sense and appears to be the most logical use for overall human benefit. In this manner, trash fish/low-value fish contributes to food security by increasing income generation opportunities and hence contributes to poverty alleviation. Another factor that needs to be taken into account is the large numbers of artisanal fishers who harvest this raw material. The continued use of trash fish/low-value fish, therefore, allows these fishers to maintain their livelihoods¹. Admittedly, this is an area that warrants more detailed investigation, from resource use, livelihoods and economic viewpoints.

Are shocks to real output permanent or transitory? Evidence from a panel of Pacific Island countries

Panel unit root and stationarity tests without structural breaks suggest that for eight Pacific island economies real gross domestic product (GDP) per capita contains a unit root. The panel stationarity test that accommodates structural change in the trend function, however, finds evidence in favour of regimewise trend stationarity. This result points to the importance of taking structural breaks into account. The finding implies that, for the period considered, the permanent secular component of output is dominated by transitory fluctuations accompanied by infrequent changes in the trend function. The only exceptions are Fiji and Kiribati, for which individual stationarity tests with multiple structural breaks suggest that real GDP per capita contains a unit root.

A global gap analysis of sea turtle protection coverage

 Although the number and extent of protected areas (PAs) are continuously increasing, their coverage of global biodiversity, as well as criteria and targets that underline their selection, warrants scrutiny. As a case study, we use a global dataset of sea turtle nesting sites (. n=. 2991) to determine the extent to which the existing global PA network encompasses nesting habitats (beaches) that are vital for the persistence of the seven sea turtle species. The majority of nesting sites (87%) are in the tropics, and are mainly hosted by developing countries. Developing countries contain 82% nesting sites, which provide lower protection coverage compared to developed countries. PAs encompass 25% of all nesting sites, of which 78% are in marine PAs. At present, most nesting sites in PAs with IUCN ratification receive high protection. We identified the countries that provide the highest and lowest nesting site protection coverage, and detected gaps in species-level protection effort within countries. No clear trend in protection coverage was found in relation to gross domestic product, the Global Peace Index or sea turtle regional management units; however, countries in crisis (civil unrest, war or natural catastrophes) provided slightly higher protection coverage of all countries. We conclude that global sea turtle resilience against threats spanning temperate to tropical regions require representative PA coverage at the species level within countries. This work is anticipated to function as a first step towards identifying specific countries or regions that should receive higher conservation interest by national and international bodies. © 2014 Elsevier Ltd.

Problems and prospects for corporate governance in Bangladesh: Some case studies basis analysis

Bangladesh is one of the least economically developed countries in the world. A lack of corporate governance creates problem for the economic development of the country. This study has been undertaken to observe whether corporate governance is being well-executed in Bangladesh and to inform views about which approach to corporate governance will be more acceptable to the county. The study has examined six cases to see whether corporate governance is properly utilised in the country. It is suggested that monetary, fiscal and exchange rate policies should be applied with appropriate diligence by the Securities and Exchange Commission, the Bangladesh Bank and the National Board of Revenue. It is expected that value can be added through arranging primary and supportive activities. Attention to inbound and outbound logistics is likely to improve productivity, enhancing profitability, long run sustainability and creating distinct competencies for the Bangladesh economy. Ultimately this may help to improve gross domestic product and the basic needs of the population.
