Derecho y religión. Una conversación imaginaria con un jurista medieval

Este fue el final de la entrevista. Yo había resuelto lo que quería preguntarle. Cuando se marchó estaba confundido. Este hombre era totalmente desconcertante, realmente escribía sobre el Derecho como un romano y pensaba sobre la naturaleza humana como un griego y, hacia valoraciones como un cristiano del siglo primero, con desprecio total de 10 que podrían ser las leyes históricas. Eso en cualquier caso es 10 que dijo que estaba haciendo. ¿Cuál fue entonces la influencia de la religión sobre el Derecho? Si alguna vez la religión influyó sobre el Derecho en occidente esto debió, ocurrir en la Edad de la Fe, en la Edad Media. La respuesta, cuando se me ocurrió fue clara. El hombre con el que estuve hablando creía en un Dios cuya gracia perfeccionaba la naturaleza pero no la destruía. Sólo porque sus teólogos creían en esta relación entre la naturaleza creada y la gracia divina llegaba a tener claro 10 que es la naturaleza humana, así esperaba encontrar respuestas mediante el uso de la razón natural. Sólo porque él mismo creía que la naturaleza del hombre hacía las leyes y las obedecía, pudo confundirse sobre cómo interpretar las leyes que los romanos habían hecho. Puedo imaginar las teologías que lo hicieron posible o que anularon su significado. Pero esa no era su teología. El creía en un Dios que creaba la naturaleza, que creó al hombre, que le dejaba libre para seguir sus propias normas y hacerlas de acuerdo con su naturaleza. Su teología era aquella que estaba al servicio de Dios y evitaba el pecado, una que debía aprender lo que podía sobre la naturaleza humana a partir de las mejores autoridades que resultaban ser los griegos, y sobre cómo el hombre puede regular sabiamente su vida social a partir de las mejores autoridades que resultaban ser los romanos. Lo que necesitamos explicar, decidí, es cómo las tradiciones de la filosofía griega y el Derecho Romano pueden florecer bajo su teología. Lo que necesitamos que esté claro es cómo el Derecho ha sobrevivido en el ambiente teológico del siglo XX. Cuando estudiaba la Licenciatura, cursé asignaturas que estarían comprendidas en lo que mi interlocutor llamaba teología y que en nuestro tiempo son impartidas por profesores de psicología, de economía, de teoría política, de filosofía y de historia. Los psicólogos hablaban a veces del sexo y de la represión o de los condicionamientos. Los economistas de la utilidad, concepto con el que parecían dar a entender que se hacía lo que uno creía. La mayoría de los filósofos hablaban de la lógica simbólica, del lenguaje pero rara vez de la ética. Los que hablaban sobre ética decían que no podía basarse en la lógica. Los teóricos de la política hablaban de libertad sin explicar que una persona debe ser libre para actuar y consecuentemente sin explicar muy convincentemente dónde la libertad de una persona terminaba y empezaba la de otra. Los historiadores algunas veces hablaban de que una ley evitaba que dos personas viviendo en tiempos diferentes podrían pensar lo mismo acerca de las mismas cosas. Las Facultades de Derecho eran bastante diferentes. Me enseñaron a analizar el comportamiento humano en los términos de la libertad de elección y responsabilidad, y no de la represión y condicionamiento. Me enseñaron a pensar sobre las relaciones humanas en términos de justicia y no de utilidad. Me enseñaron a ser lógico con los problemas de justicia. Aprendí que había diferentes tipos de libertad humana con límites diferentes y que no todos tenían el mismo valor. Sin embargo, y esto es bastante curioso, los profesores que me enseñaron Derecho parecían en su mayor parte creer en las teorías de los psicológos, economistas, los teóricos de la política, los filósofos y los historiadores. Es difícil explicar por qué el Derecho florece y actua de forma eficaz en nuestra época bajo la sombra de estas creencias, más difícil incluso de creer cómo el Derecho floreció en la Edad de la Fe con su teología de la gracia y la naturaleza. Se me ocurre una explicación posible. Es la siguiente: realmente la naturaleza humana se gobierna a sí misma mediante la ley y esta naturaleza se reafirmará a sí misma de forma indefectible incluso aunque se niegue contínuamente

HALOE Algorithm Improvements for Upper Tropospheric Sounding

This report details the ongoing efforts by GATS, Inc., in conjunction with Hampton University and University of Wyoming, in NASA's Mission to Planet Earth UARS Science Investigator Program entitled "HALOE Algorithm Improvements for Upper Tropospheric Soundings." The goal of this effort is to develop and implement major inversion and processing improvements that will extend HALOE measurements further into the troposphere. In particular, O3, H2O, and CH4 retrievals may be extended into the middle troposphere, and NO, HCl and possibly HF into the upper troposphere. Key areas of research being carried out to accomplish this include: pointing/tracking analysis; cloud identification and modeling; simultaneous multichannel retrieval capability; forward model improvements; high vertical-resolution gas filter channel retrievals; a refined temperature retrieval; robust error analyses; long-term trend reliability studies; and data validation. The current (first-year) effort concentrates on the pointer/tracker correction algorithms, cloud filtering and validation, and multi-channel retrieval development. However, these areas are all highly coupled, so progress in one area benefits from and sometimes depends on work in others

Application of Commercial Non-Dispersive Infrared Spectroscopy Sensors for Sub-Ambient Carbon Dioxide Detection

Monitoring carbon dioxide (CO2) concentration within a spacecraft or spacesuit is critically important to ensuring the safety of the crew. Carbon dioxide uniquely absorbs light at wavelengths of 3.95 micrometers and 4.26 micrometers. As a result, non-dispersive infrared (NDIR) spectroscopy can be employed as a reliable and inexpensive method for the quantification of CO2 within the atmosphere. A multitude of commercial-off-the-shelf (COTS) NDIR sensors exist for CO2 quantification. The COTS sensors provide reasonable accuracy so long as the measurements are attained under conditions close to the calibration conditions of the sensor (typically 21.1 C and 1 atm). However, as pressure deviates from atmospheric to the pressures associated with a spacecraft (8.0-10.2 PSIA) or spacesuit (4.1-8.0 PSIA), the error in the measurement grows increasingly large. In addition to pressure and temperature dependencies, the infrared transmissivity through a volume of gas also depends on the composition of the gas. As the composition is not known a priori, accurate sub-ambient detection must rely on iterative sensor compensation techniques. This manuscript describes the development of recursive compensation algorithms for sub-ambient detection of CO2 with COTS NDIR sensors. In addition, the basis of the exponential loss in accuracy is developed theoretically considering thermal, Doppler, and Lorentz broadening effects which arise as a result of the temperature, pressure, and composition of the gas mixture under analysis. As a result, this manuscript provides an approach to employing COTS sensors at sub-ambient conditions and may also lend insight into designing future NDIR sensors for aerospace application

Errors in Sounding of the Atmosphere Using Broadband Emission Radiometry (SABER) Kinetic Temperature Caused by Non-Local Thermodynamic Equilibrium Model Parameters

The vast set of near global and continuous atmospheric measurements made by the SABER instrument since 2002, including daytime and nighttime kinetic temperature (T(sub k)) from 20 to 105 km, is available to the scientific community. The temperature is retrieved from SABER measurements of the atmospheric 15 micron CO2 limb emission. This emission separates from local thermodynamic equilibrium (LTE) conditions in the rarefied mesosphere and thermosphere, making it necessary to consider the CO2 vibrational state non-LTE populations in the retrieval algorithm above 70 km. Those populations depend on kinetic parameters describing the rate at which energy exchange between atmospheric molecules take place, but some of these collisional rates are not well known. We consider current uncertainties in the rates of quenching of CO2 (v2 ) by N2 , O2 and O, and the CO2 (v2 ) vibrational-vibrational exchange to estimate their impact on SABER T(sub k) for different atmospheric conditions. The T(sub k) is more sensitive to the uncertainty in the latter two and their effects depend on altitude. The T(sub k) combined systematic error due to non-LTE kinetic parameters does not exceed +/- 1.5 K below 95 km and +/- 4-5 K at 100 km for most latitudes and seasons (except for polar summer) if the Tk profile does not have pronounced vertical structure. The error is +/- 3 K at 80 km, +/- 6 K at 84 km and +/- 18 K at 100 km under the less favourable polar summer conditions. For strong temperature inversion layers, the errors reach +/- 3 K at 82 km and +/- 8 K at 90 km. This particularly affects tide amplitude estimates, with errors of up to +/- 3 K

Version 1.3 AIM SOFIE Measured Methane (CH4): Validation and Seasonal Climatology

The V1.3 methane (CH4) measured by the Aeronomy of Ice in the Mesosphere (AIM) Solar Occultation for Ice Experiment (SOFIE) instrument is validated in the vertical range of ~25–70 km. The random error for SOFIE CH4 is ~0.1–1% up to ~50 km and degrades to ~9% at ∼ 70 km. The systematic error remains at ~4% throughout the stratosphere and lower mesosphere. Comparisons with CH4 data taken by the SCISAT Atmospheric Chemistry Experiment-Fourier Transform Spectrometer (ACE-FTS) and the Envisat Michelson Interferometer for Passive Atmospheric Sounding (MIPAS) show an agreement within ~15% in the altitude range ~30–60 km. Below ~25 km SOFIE CH4 is systematically higher (≥20%), while above ~65 km it is lower by a similar percentage. The sign change from the positive to negative bias occurs between ~55 km and ~60 km (or ~40 km and ~45 km) in the Northern (or Southern) Hemisphere. Methane, H2O, and 2CH4 + H2O yearly differences from their values in 2009 are examined using SOFIE and MIPAS CH4 and the Aura Microwave Limb Sounder (MLS) measured H2O. It is concluded that 2CH4 + H2O is conserved with altitude up to an upper limit between ~35 km and ~50 km depending on the season. In summer this altitude is higher. In the Northern Hemisphere the difference relative to 2009 is the largest in late spring and the established difference prevails throughout summer and fall, suggesting that summer and fall are dynamically quiet. In both hemispheres during winter there are disturbances (with a period of ~1 month) that travel downward throughout the stratosphere with a speed similar to the winter descent. ©2016.

Energy Transport in the Thermosphere During the Solar Storms of April 2002

The dramatic solar storm events of April 2002 deposited a large amount of energy into the Earth's upper atmosphere, substantially altering the thermal structure, the chemical composition, the dynamics, and the radiative environment. We examine the flow of energy within the thermosphere during this storm period from the perspective of infrared radiation transport and heat conduction. Observations from the SABER instrument on the TIMED satellite are coupled with computations based on the ASPEN thermospheric general circulation model to assess the energy flow. The dominant radiative response is associated with dramatically enhanced infrared emission from nitric oxide at 5.3 microns from which a total of approx. 7.7 x 10(exp 23) ergs of energy are radiated during the storm. Energy loss rates due to NO emission exceed 2200 Kelvin per day. In contrast, energy loss from carbon dioxide emission at 15 microns is only approx. 2.3% that of nitric oxide. Atomic oxygen emission at 63 microns is essentially constant during the storm. Energy loss from molecular heat conduction may be as large as 3.8% of the NO emission. These results confirm the "natural thermostat" effect of nitric oxide emission as the primary mechanism by which storm energy is lost from the thermosphere below 210 km

Solar-Terrestrial Coupling Evidenced by Periodic Behavior in Geomagnetic Indexes and the Infrared Energy Budget of the Thermosphere

We examine time series of the daily global power (W) radiated by carbon dioxide (at 15 microns) and by nitric oxide (at 5.3 microns) from the Earth s thermosphere between 100 km and 200 km altitude. Also examined is a time series of the daily absorbed solar ultraviolet power in the same altitude region in the wavelength span 0 to 175 nm. The infrared data are derived from the SABER instrument and the solar data are derived from the SEE instrument, both on the NASA TIMED satellite. The time series cover nearly 5 years from 2002 through 2006. The infrared and solar time series exhibit a decrease in radiated and absorbed power consistent with the declining phase of the current 11-year solar cycle. The infrared time series also exhibits high frequency variations that are not evident in the solar power time series. Spectral analysis shows a statistically significant 9-day periodicity in the infrared data but not in the solar data. A very strong 9-day periodicity is also found to exist in the time series of daily A(sub p) and K(sub p) geomagnetic indexes. These 9-day periodicities are linked to the recurrence of coronal holes on the Sun. These results demonstrate a direct coupling between the upper atmosphere of the Sun and the infrared energy budget of the thermosphere

Zinc-finger recombinase activities in vitro

Zinc-finger recombinases (ZFRs) are chimaeric proteins comprising a serine recombinase catalytic domain linked to a zinc-finger DNA binding domain. ZFRs can be tailored to promote site-specific recombination at diverse ‘Z-sites’, which each comprise a central core sequence flanked by zinc-finger domain-binding motifs. Here, we show that purified ZFRs catalyse efficient high-specificity reciprocal recombination between pairs of Z-sites in vitro. No off-site activity was detected. Under different reaction conditions, ZFRs can catalyse Z-site-specific double-strand DNA cleavage. ZFR recombination activity in Escherichia coli and in vitro is highly dependent on the length of the Z-site core sequence. We show that this length effect is manifested at reaction steps prior to formation of recombinants (binding, synapsis and DNA cleavage). The design of the ZFR protein itself is also a crucial variable affecting activity. A ZFR with a very short (2 amino acids) peptide linkage between the catalytic and zinc-finger domains has high activity in vitro, whereas a ZFR with a very long linker was less recombination-proficient and less sensitive to variations in Z-site length. We discuss the causes of these phenomena, and their implications for practical applications of ZFRs

Global and long-term comparison of SCIAMACHY limb ozone profiles with correlative satellite data (2002–2008)

SCIAMACHY limb scatter ozone profiles from 2002 to 2008 have been compared with MLS (2005–2008), SABER (2002–2008), SAGE II (2002–2005), HALOE (2002–2005) and ACE-FTS (2004–2008) measurements. The comparison is performed for global zonal averages and heights from 10 to 50 km in one km steps. The validation was performed by comparing monthly mean zonal means and by comparing averages over collocated profiles within a zonal band and month. Both approaches yield similar results. For most of the stratosphere SCIAMACHY agrees to within 10% or better with other correlative data. A systematic bias of SCIAMACHY ozone of up to 100% between 10 and 20 km in the tropics points to some remaining issues with regard to convective cloud interference. Statistical hypothesis testing reveals at which altitudes and in which region differences between SCIAMACHY and other satellite data are statistically significant. We also estimated linear trends from monthly mean data for different periods where SCIAMACHY has common observations with other satellite data using a classical trend model with QBO and seasonal terms in order to draw conclusions on potential instrumental drifts as a function of latitude and altitude. Since the time periods considered here are rather short these trend estimates are only used to identify potential instrumental issues with the SCIAMACHY data. As a result SCIAMACHY exhibits a statistically significant negative trend in the range of of about 1–3% per year depending on latitude during the period 2002–2005 (overlapping with HALOE and SAGE II) and somewhat less during 2002–2008 (overlapping with SABER) in the altitude range of 30–40 km, while in the period 2004–2008 (overlapping with MLS and ACE-FTS) no significant trends are observed. Since all correlative satellite instruments do not show to a very large extent statistically significant trends in any of the time periods considered here, the negative trends observed with SCIAMACHY data point at some remaining instrumental artifact which is most likely related to residual errors in the tangent height registration of SCIAMACHY
