Estudio descriptivo del consumo de alcohol en los adolescentes de Gandia
2014
Resumen Introducción: La morbimortalidad en los países desarrollados se relaciona con hábitos adquiridos en la adolescencia. El alcohol es la droga más consumida por los adolescentes españoles, planteando su uso abusivo un problema preocupante para la salud pública. Objetivo: Valorar el patrón de consumo de bebidas alcohólicas de los jóvenes estudiantes de 4º de ESO de la ciudad de Gandía y las características que definen a esta población y al entorno en el que se realiza. Metodología: Se trata de un estudio descriptivo transversal del consumo de alcohol en los adolescentes de entre 15 y 18 años de Gandía, que se lleva a cabo mediante una encuesta con diferentes cuestiones relacionadas con l…
A review on optimization and cost-optimal methodologies in low-energy buildings design and environmental considerations
2019
Abstract The topic of low-energy buildings received a widespread and growing interest in last years, thanks to energy saving policies of developed countries. The design of a low-energy building is addressed with energy saving measures and renewable energy generation, but the correct assessment of phenomena occurring in a building usually requires to perform dynamic simulations and to analyze multiple scenarios to attain the optimal solution. The optimality of a technical solution may be subject to contrasting constraints and objectives. For this reason, designers may employ mathematical optimization techniques, a non-familiar topic to most of building designers. In this paper, a review on o…
Disentangling nutrition facts from fiction : towards healthy and sustainable consumption in industrialized societies
2020
Over the last centuries, in the context of industrialization, globalization and urbanization, profound dietary changes have occurred. Ubiquitous access to cheap, readily available and highly palatable unhealthy products, together with aggressive marketing that forcefully impacts social norms, have led to overconsumption of energy-dense, nutrient-poor foods. This has not only been associated with a higher prevalence of obesity and diet-related non-communicable diseases, but also with detrimental effects on the world’s natural resources. Broader and braver public health measures favoring the availability and affordability of healthy, minimally processed foods should be implemented in conjunct…
Secure and sustainable but not as prominent among the ambivalent: Attachment style and proenvironmental consumption
2021
Abstract Human activity has degraded the environment and contributed to numerous public health hazards. Thus, the United Nations recently made an urgent call to develop sustainable consumption practices. Although existing literature has acknowledged attachment style as a potential predictor of certain consumption responses, its influence on proenvironmental consumption has not yet been examined. We conducted a large-sampled study (N = 1397) on this topic and found securely attached individuals to report significantly higher scores on a scale measuring proenvironmental consumption compared to people with anxious/ambivalent and avoidant attachment styles, respectively. The latter two groups d…
The Impact of Government Spending on the Private Sector: Crowding-out versus Crowding-in Effects
2011
Summary We contribute to the empirical literature on the effect of government spending on economic activity, by assessing the impact of changes in government spending-GDP ratio on (the short-term growth rates of) private consumption and investment. We do this by analysing a panel sample of 145 countries from 1960 to 2007. The results of our paper suggest that government spending produces important crowding-out effects, by negatively affecting both private consumption and investment. The result is broadly robust to both country and time effects, and different econometric specifications. In addition, we show that the effect of government consumption on private consumption and investment does …
Household Leverage and Fiscal Multipliers
2011
We study the size of fiscal multipliers in response to a government spending shock under different household leverage conditions in a general equilibrium setting with search and matching frictions. We allow for different levels of household indebtedness by changing the intensive margin of borrowing (loan-to-value ratio), as well as the extensive margin, defined as the number of borrowers over total population. The interaction between the consumption decisions of agents with limited access to credit and the process of wage bargaining and vacancy posting delivers two main results: (a) higher initial leverage makes it more likely to find output multipliers higher than one; and (b) a positive g…
Optimal Dynamics of Functionality Development in Open Innovation
2009
Abstract Sustainable functionality development has become crucial option for firm's survival in a new paradigm confronting a post-information society. This can be realized by earlier emergence of functionality development. In this context, effective utilization of external innovation resources leads to follower substitution for leader in open innovation. This substitution induces advancements of innovative goods by substituting gratification of their consumption for resistance to them. Thus, optimization of utmost gratification of consumption under certain investment would be crucial for firm strategy. Optimal functionality development dynamics is analyzed in this paper by integrating produ…
Is participation in the tourism market an opportunity for everyone? Some evidence from Italy
2016
This paper investigates whether there are differences in tourism consumption behaviour among families by analysing the main determinants of tourism participation at national and international levels. In particular, it explores whether tourism is becoming part of the lifestyle of Italians or whether it is still a luxury good only for the privileged. A Heckman model was used on micro-data on Italian family expenditure over the period 1997–2007, and an income elasticity analysis for different personal and household characteristics was carried out. The results show that participation in the tourism market is strongly affected by the personal characteristics of individuals and that tourism cons…
Assessing eco-efficiency with directional distance functions
2012
Abstract Eco-efficiency is a matter of concern at present that is receiving increasing attention in political, academic and business circles. Broadly speaking, this concept refers to the ability to create more goods and services with less impact on the environment and less consumption of natural resources, thus involving both economic and also ecological issues. In this paper we propose the use of directional distance functions and Data Envelopment Analysis techniques to assess eco-efficiency. More specifically, we show how these functions can be used to compute a wide range of indicators representing different objectives regarding economic and ecological performance. This methodological ap…
Household carbon footprints in the Baltic States: A global multi-regional input–output analysis from 1995 to 2011
2017
The paper analyzes consumption related household CO2 equivalent (CO2e) emissions for the three Baltic States – Estonia, Latvia and Lithuania from 1995 to 2011. The analysis is based on a multi-regional input–output model, which allows us to estimate life-cycle emissions for all major household consumption items. Results demonstrate that household carbon footprints in all the Baltic States significantly increased by 47% in Estonia, 20% in Latvia and 52% in Lithuania during the study period. In 2011 in Estonia expenditures for housing and utility contributed the highest per capita life-cycle emissions – 43%. However, in Lithuania housing accounted only for 16% of per capita emissions, but foo…
