of this essay is to reflexively consider the particular way in which Jürgen
Habermas faces some theoretical challenges that are particularly interesting to
contemporary anthropological thought, i.e., the issue of cultural translation
and the presence of religion in the public sphere.
With the purpose of studying the
influence of population dynamics and economic growth on energy consumption and
carbon emissions, an endogenous economic growth model is proposed incorporating
physical and human capital and using an Agent-Based Model. The model can test
different development strategies by identifying the key factors existing at the
agent level that may speed up or slow down a given path, and therefore it is an
interesting tool to develop and to test mitigation and/or adaptation measures.
Favorable scenarios may be possible in societies that encourage investment in
human capital through education and technological development, provided that
this is accompanied by a reduction in consumption rates and the creation of
physical capital by the population. Moreover, this model shows that human
capital resulting from education not only raises productivity, but also plays a
key role in the development and adoption of new technologies that drive
Several modes of eukaryotic of DNA double strand break
repair (DSBR) depend on synapsis of complementary DNA. The Rad51 ATPase, the S.
cerevisiae homolog of E. coli RecA, plays a key role in this process
by catalyzing homology searching and strand exchange between an invading DNA
strand and a repair template (e.g. sister chromatid or homologous chromosome).
Synthesis dependent strand annealing (SDSA), a mode of DSBR, requires Rad51.
Another repair enzyme, the Rad1-Rad10 endonuclease, acts in the final stages of
SDSA, hydrolyzing 3￠ overhanging
single-stranded DNA. Here we show in vivo by fluo-rescence microscopy that the ATP binding function of yeast Rad51 is required to recruit
Rad10 SDSA sites indicating that Rad51 pre-synaptic filament formation must
occur prior to the recruitment of Rad1-Rad10. Our data also show that Rad51 ATPase
activity, an important step in Rad51 filament disassembly, is not absolutely
required in order to recruit Rad1- Rad10 to DSB sites.
Short-term and mid-term projections of
energy consumption and carbon emissions raise significant concern about the
availability of the necessary energy resources to meet the growing demand and
about the impact of emissions on global change. Different macroeconomic models
address this issue through global variables, such as gross domestic product,
production of goods and services, total population and natural resources
extraction. However, the relations among these variables are neither linear nor simple. In an attempt to base
said relations on a “bottom-up” perspective, the individual behavior of
representative agents of economy, in terms of energy consumption and related
carbon emissions, was studied, with particular emphasis on their investment in
human capital. It was found that a higher investment in human capital (e.g.,
education, research) was translated into a better distribution of consumption,
with a higher level of energy efficiency and a slight improvement in carbon
