Medio ambiente y desarrollo: una revisión conceptual

2008

This paper provides a conceptual review of the term “sustainable development”, bearing in mind its current applicability to social matters and public decision-making. Taking the well-known definition of sustainable development coined by the Brundtland Commission over twenty years ago, we consider the consequences of adopting weak and strong sustainability criteria for continued development and the importance of conserving so-called critical natural capital. We also examine the relationship between sustainable development and equity. We then present a concept of development that integrates the three areas of economic, social and environmental sustainability. Finally, we discuss the main forc…

In Search of Determinants of Time-Discounting in Monetary Choices : Personal Characteristics Matter Only a Little

2022

Time-discounting in monetary choices is determined by aspects related to the reward, contextual factors and characteristics of a person. In the present study, we used three datasets (Ndata1 = 419; Ndata2 = 485; Ndata3 = 240) to examine how well personal characteristics (sociodemographic, financial situation, self-control, cognitive abilities, negative experiencing, and trustfulness) predict time-discounting in both hypothetical and real reward scenarios. The results of the regression analyses indicate that the characteristics of a person only explain a small proportion of the variance in time-discounting (R2 ranged from .10 to .19). The only substantive predictors of time-discounting in mon…

Effects of High Frequency Repetitive Transcranial Magnetic Stimulation (HF-rTMS) on Delay Discounting in Major Depressive Disorder: An Open-Label Unc…

2019

Background: Delay discounting (DD) refers to the decrease of a present subjective value of a future reward as the delay of its delivery increases. Major depressive disorder (MDD), besides core emotional and physical symptoms, involves difficulties in reward processing. Depressed patients often display greater temporal discounting rates than healthy subjects. Repetitive transcranial magnetic stimulation (rTMS) is a non-invasive brain stimulation technique applied in several countries to adult patients with treatment resistant depression. Studies suggest that this technique can be used to modulate DD, but no trial has assessed its effects on depressed patients. Methods: In this open-label unc…

Can transcranial direct current stimulation (tDCS) improve impulsivity in healthy and psychiatric adult populations? A systematic review.

2020

Impulsivity is a multidimensional phenomenon that remains hard to define. It compounds the core pathological construct of many neuropsychiatric illnesses, and despite its close relation to suicide risk, it currently has no specific treatment. Transcranial direct current stimulation (tDCS) is a non-invasive brain stimulation technique whose application results in cognitive function improvement, both in healthy and psychiatric populations. Following PRISMA recommendations, a systematic review of the literature concerning tDCS's effects on impulsive behaviour was performed using the PubMed database. The research was based on the combination of the keyword 'tDCS' with 'impulsivity', 'response i…

Limits to Arbitrage and Interest Rates: a Debate Between Keynes, Hawtrey and Hicks

2018

International audience; This paper deals with a debate between Hawtrey, Hicks and Keynes concerning the capacity of the central bank to influence the short-term and the long-term rates of interest. Both Hawtrey and Keynes considered the central bank’s ability to influence short-term rates of interest. However, they do not put the same emphasis on the study of the long-term rates of interest. According to Keynes, long-term rates are influenced by future expected short-term rates (1930, 1936), whereas for Hawtrey (1932, 1937, 1938), long-term rates are more dependent on the business cycle. Short-term rates do not have much effect on long-term rates according to Hawtrey. In 1939, Hicks enters …

Economic Aspects of Hybrid Cloud Infrastructure: User Organization Perspective

2012

Adoption of cloud infrastructure promises enterprises numerous bene- ts, such as faster time-to-market and improved scalability enabled by on-demand provisioning of pooled and shared computing resources. In particular, hybrid clouds, by combining the private in-house capacity with the on-demand capacity of public clouds, promise to achieve both increased utilization rate of the in-house infrastructure and limited use of the more expensive public cloud, thereby lowering the total costs for a cloud user organization. In this paper, an analytical model of hybrid cloud costs is introduced, wherein the costs of computing and data communication are taken into account. Using this model, a cost-e c…
