From urban political economy to the cultural political economy : rethinking culture and economy in and beyond the urban

Discussions about the culture-economy articulation have occurred largely within theconfines of economic geography. In addition, much attention has been diverted intocaricaturized discussions over the demise of political economy or the invalidity ofculturalist arguments. Moving the argument from the inquiry on the ¿nature¿ of theeconomy itself to the transformation of the role of culture and economy inunderstanding the production of the urban form from an urban political economy (UPE)this paper focuses on how the challenges posed by the cultural turn have enabled urbanpolitical economy to participate constructively in interdisciplinary efforts to reorientpolitical economy in the direction of a critical cultural political economy.

Identifying strategies for mitigating the global warming impact of the EU-25 economy using a multi-objective input-output approach

Global warming mitigation has recently become a priority worldwide. A large body of literature dealing with energy related problems has focused on reducing greenhouse gases emissions at an engineering scale. In contrast, the minimization of climate change at a wider macroeconomic level has so far received much less attention. We investigate here the issue of how to mitigate global warming by performing changes in an economy. To this end, we make use of a systematic tool that combines three methods: linear programming, environmentally extended input output models, and life cycle assessment principles. The problem of identifying key economic sectors that contribute significantly to global warming is posed in mathematical terms as a bi criteria linear program that seeks to optimize simultaneously the total economic output and the total life cycle CO2 emissions. We have applied this approach to the European Union economy, finding that significant reductions in global warming potential can be attained by regulating specific economic sectors. Our tool is intended to aid policymakers in the design of more effective public policies for achieving the environmental and economic targets sought.

Is the wage curve formal or informal? Evidence for Colombia

The objective of this paper is to analyse the existente or not of a wage curve in Colombia, paying special attention to the differences between formal and informal workers, an issue that has been systematically ignored in the wage curve literature. The obtained results using microdata from the Colombian Continuous Household Survey (CHS) between 2002 and 2006 show the existence of a wage curve with a negative slope for the Colombian economy. Using information on metropolitan areas, the estimates of the elasticity of individual wages to local unemployment rates was -0.07, a value that is very close to those obtained for other countries. However, the disaggregation of statistical information for formal and informal workers has shown significant differences among both groups of workers. In particular, for the less protected groups of the labour market, informal workers (both men and women), a high negatively sloped wage curve was found. This result is consistent with the conclusions from efficiency wage theoretical models and should be taken into account when analysing the functioning of regional labour markets in developing countries.

Establishing Zebrafish as a Novel Exercise Model: Swimming Economy, Swimming-enhanced Growth and Muscle Growth Marker Gene Expression

Zebrafish has been largely accepted as a vertebrate multidisciplinary model but its usefulness as a model for exercise physiology has been hampered by the scarce knowledge on its swimming economy, optimal swimming speeds and cost of transport. Therefore, we have performed individual and group-wise swimming experiments to quantify swimming economy and to demonstrate the exercise effects on growth in adult zebrafish.

Energiansäästö kotitalouksien valaistuksessa Suomessa

Tässä työssä arvioidaan kotitalouksien energiansäästöpotentiaalia valaistuksen osalta Suomessa. Euroopan Unioni on ratifioinut päästövähennystavoitteen 20 % koskien kaikkia primäärienergiantuotantomuotoja. Päästövähennystavoite on tarkoitus toteuttaa vuoteen 2020 mennessä. Tässä kandidaatintyössä arvioidaan saavutettavissa olevaa energiansäästöpotentiaalia Suomessa kotitalouksissa laitesähkön osalta. Energiansäästöpotentiaalin arviointi perustuu hehkulampun korvaamismahdollisuuksien vertailuun. Valaistuksessa voidaan saavuttaa jopa 75 % sähkönsäästö, kun korvataan yksi 60 W hehkulamppu vastaavan valomäärän tuottavalla energiansäästölampulla. Kokonaisuudessa kotitalouksien valaistuksessa on tehostamispotentiaalia noin 60 %. Valaistuksen tehostamisella saavutetaan noin 1,5 TWh säästö Suomen kokonaissähkökulutuksessa. Saavutettavat säästöt voivat olla jopa suuremmatkin, jos käytetään lisäksi älykästä valonohjausta. Johtopäätöksenä voidaan todeta, että tehostamispotentiaalia on merkittävästi ja tehostaminen on yksittäiselle kotitaloudelle taloudellisesti kannattavaa. Energiansäästöpotentiaalin toteuttamisen vaikutuksia kansantalouteen ei ole arvioitu.

Economy of converting wood to biocoal

The pre-treatment step has a significant influence on the performance of bioenergy chains, especially on logistics. In nowadays conditions it is important to have technologies allowing to convert biomass at modest scales into dense energy carriers that ease transportation and handling. There are such technologies as charring and torrefaction. It is a thermal treatment of organic waste (only woody biomass is considered as a raw material in this work), which aims to produce a fuel with increased energy density. Wood processing is attractive under meaning of green house gas emissions. Charring and torrefaction are promising technologies due to its high process efficiency. It may be also attractive in the future as a renewable fuel with improved storage properties, increased energy density (compared to raw wood) for co-combustion and/or gasification.

Convergence and divergence in global economy and social development : global perspectives on the contents of economic and soical development policy and its effects on rich and poor countries

The study of convergence and divergence in global economy and social development utilises comparative indicators to investigate the contents of economic and social development policy and their effects on the global samples that represent the rich industrial, semi-industrial and the poor developing nations. The study searchesfor answers to questions such as "what are the objectives of economic growth policies in globalisation under the imperatives of convergence and divergence, and how do these affect human well-being in consideration to the objectives of social policy in various nations?" The empirical verification of data utilises the concepts of the `logic of industrialism´ for comparative analysis that focuses mainly on identifying the levels of well-being in world nations after the Second World War. The perspectives of convergence and divergence in global economy and social development critically examine the stages of early development processes in global economy, distinguish the differences between economy and social development, illustrate the contents of economic and social development policies, their effects on rich and poor countries, and the nature of convergence and divergence in propelling economic growth and unequal social development in world nations. The measurement of convergence and divergence in global economy and social development utilised both economic and social data that were combined into an index that measures the precise levels of the effects of economic and social development policies on human well-being in the rich and poor nations. The task of finding policy solutions to resolve the controversies are reviewed through empirical investigations and the analyses of trends indicated within economic and social indicators and data. These revealed how the adoption of social policy measures in translating the gains from economic growth, towards promoting education, public health, and equity, generate social progress and longer life expectancy, higher economic growth, and sustain more stable macro economy for the nations. Social policy is concerned with the translation of benefits from objectives of global economic growth policies, to objectives of social development policy in nation states. Social policy, therefore, represents an open door whereby benefits of economic growth policies are linked with the broader objectives of social development policy, thereby enhancing the possibility of extending benefits from economic growth to all human being in every nation.

Factors associated with fragility fractures in women over 50 years of age: a population-based household survey

PURPOSE: To analyze the prevalence of and factors associated with fragility fractures in Brazilian women aged 50 years and older. METHODS: This cross-sectional population survey, conducted between May 10 and October 31, 2011, included 622 women aged >50 years living in a city in southeastern Brazil. A questionnaire was administered to each woman by a trained interviewer. The associations between the occurrence of a fragility fracture after age 50 years and sociodemographic data, health-related habits and problems, self-perception of health and evaluation of functional capacity were determined by the χ2 test and Poisson regression using the backward selection criteria. RESULTS: The mean age of the 622 women was 64.1 years. The prevalence of fragility fractures was 10.8%, with 1.8% reporting hip fracture. In the final statistical model, a longer time since menopause (PR 1.03; 95%CI 1.01-1.05; p<0.01) and osteoporosis (PR 1.97; 95%CI 1.27-3.08; p<0.01) were associated with a higher prevalence of fractures. CONCLUSIONS: These findings may provide a better understanding of the risk factors associated with fragility fractures in Brazilian women and emphasize the importance of performing bone densitometry.
