Atmospheric Dust on Mars: A Review
No full textFrancois Forget, Laboratoire de Météorologie Dynamique (LMD), Institut Pierre Simon Laplace (IPSL), The National Center for Scientific Research (CNRS), FranceLuca Montabone, Laboratoire de Météorologie Dynamique (LMD), Space Science Institute (SSI), FranceICES510: Planetary and Spacecraft Dust Properties and Mitigation TechnologiesThe 47th International Conference on Environmental Systems was held in South Carolina, USA on 16 July 2017 through 20 July 2017.The Martian environment is characterized by airborne mineral dust extending between the surface and up to 80 km altitude. This dust plays a key role in the climate system and in the atmospheric variability. It is a significant issue for any system on the surface. The atmospheric dust content is highly variable in space and time. In the past 20 years, many investigations have been conducted to better understand the characteristics of the dust particles, their distribution and their variability. However, many unknowns remain. We still don't know precisely the composition of the dust particles and notably their density, a key parameter when modeling their abrasion.
The occurrence of local, regional and global dust storms are better documented and modeled, but they remain very difficult to predict. The vertical distribution of dust, characterized by detached layers exhibiting large diurnal and seasonal variations, remains quite enigmatic and very poorly modeled. Near the surface the actual dynamics of saltating dust in the surface layer (where landers and astronauts operate) is also a topic of ongoing research.
We will review our current knowledge on these subjects and discuss the implication for future exploration projects
Beauregard House
No full textGeneral view; The architect Francois Correjolles, whose creole French family emigrated from St. Domingue (Haiti), added new American Federal elements while preserving some of the traditional creole plan. The Beauregard-Keyes House, built in 1826 for wealthy auctioneer Joseph Le Carpentier, is a fine example of a raised, center-hall house. It is named for two of its former tenants, Confederate General Pierre Gustave Toutant (P.G.T.) Beauregard and author Frances Parkinson Keyes. General Beauregard lived in the home from 1866 to 1868 while he was president of the New Orleans, Jackson, and Great Northern Railroad. The home features twin curved staircases, leading to a Tuscan portico. The garden's design duplicates the original 1865 plans.

Alien theory : the decline of materialism in the name of matter
No full textThe thesis tries to define and explain the rudiments of a 'nonphilosophical'
or 'non-decisional' theory of materialism on the basis of a
theoretical framework provided by the 'non-philosophy' of Francois
Laruelle. Neither anti-philosophical nor anti-materialist in character, non-materialism
tries to construct a rigorously transcendental theory of matter by
using certain instances of philosophical materialism as its source material.
The materialist decision to identify the real with matter is seen to retain a
structural isomorphy with the phenomenological decision to identify the real
with the phenomenon. Both decisions are shown to operate on the basis of a
methodological idealism; materialism on account of its confusion of matter
and concept; phenomenology by virtue of its confusion of phenomenon and
logos. By dissolving the respectively 'materiological' and
'phenomenological' amlphibolies which are the result of the failure to effect a
rigorously transcendental separation between matter and concept on the one
hand; and between phenomenon and logos on the other, non-materialist
theory proposes to mobilise the non-hybrid or non-decisional concepts of a
'matter-without-concept' and of a 'phenomenon-without-logos' in order to
effect a unified but non-unitary theory of phenomenology and materialism.
The result is a materialisation of thinking that operates according to matter's
foreclosure to decision. That is to say, a transcendental theory of the
phenomenon that licenses limitless phenomenological plasticity,
unconstrained by the apparatus of eidetic intuition or any horizon of
apophantic disclosure; yet one which is simultaneously a transcendental
theory of matter, uncontaminated by the bounds of empirical perception and
free of all phenomenological circumscription
Cooling of the Martian thermosphere by CO2 radiation and gravity waves: An intercomparison study with two general circulation models
No full textObservations show that the lower thermosphere of Mars (approximate to 100-140km) is up to 40K colder than the current general circulation models (GCMs) can reproduce. Possible candidates for physical processes missing in the models are larger abundances of atomic oxygen facilitating stronger CO2 radiative cooling and thermal effects of gravity waves. Using two state-of-the-art Martian GCMs, the Laboratoire de Meteorologie Dynamique and Max Planck Institute models that self-consistently cover the atmosphere from the surface to the thermosphere, these physical mechanisms are investigated. Simulations demonstrate that the CO2 radiative cooling with a sufficiently large atomic oxygen abundance and the gravity wave-induced cooling can alone result in up to 40K colder temperature in the lower thermosphere. Accounting for both mechanisms produce stronger cooling at high latitudes. However, radiative cooling effects peak above the mesopause, while gravity wave cooling rates continuously increase with height. Although both mechanisms act simultaneously, these peculiarities could help to further quantify their relative contributions from future observations
Mars Atmosphere, Modeling and Observations
No full textThe goal of the workshop is to bring together experts in modeling and observations of the Mars atmosphere and climate system and to discuss the nature of the atmospheric structure, circulation, and chemistry (up to the neutral thermosphere); the dust cycle; the water cycle (vapor, clouds, and frost); the carbon dioxide cycle (polar caps and clouds); the photochemistry of the Mars atmosphere; the early atmosphere of Mars; and the evolution of the atmosphere of Mars.Lunar and Planetary Institute; NASA Mars Exploration Program; Centre National d'Etudes Spatiales (CNES); NASA Mars Program Officeworkshop co-chairs, Francois Forget, Joel S.

The ethical and moral-based dimension of leadership in CSR-oriented strategies and sustainable entrepreneurship
No full textThis chapter addresses the theme of leadership and its influence on corporate social
responsibility (CSR) and sustainability-oriented strategies. Specifically, it aims to analyse,
through a deductive and literature-based approach, the relevance of the ethical and moral
leadership models with respect to the diffusion of CSR and sustainable entrepreneurship. Linking ethical and moral-based leadership to the CSR and sustainable entrepreneurship discourse allows us to point out the relevance of an authentic orientation in supporting
change and fostering sustainable entrepreneurship The theoretical construct of responsible and sustainable leadership derives from the
intersection of the moral-based leadership concepts with those of CSR and sustainable
entrepreneurship..Drawing from these premises, this chapter seeks to identify leadership models and
attributes consistent with (and necessary to develop) an authentic CSR-oriented strategy
and able to foster sustainable entrepreneurship.
Accordingly, in this chapter, we argue that leadership represents a key aspect that
warrants more research within both CSR and sustainable entrepreneurship studies. The
research questions that orients this study can be summarised as follows: Which leadership
models favour authentic CSR practices? Are moral, ethical-based and virtues-based models
of leadership effective in developing CSR and fostering sustainable entrepreneurship?
These questions guide the critical review of the different leadership approaches, bringing
attention to the models that are most coherent in regard to the actual socio-economic
context which requires managers and entrepreneurs to govern the internal and external
complexity and actively contribute to sustainability. The methodological approach is
mainly based on a literature review that surveys critical points in current literature that is
relevant to the topic.
The work is structured as follows. First, we offer an analysis of the leadership theoretical
framework in the context of the CSR debate. We begin with a brief methodological
note, followed by an analysis of the antecedents of CSR and sustainable entrepreneurship
in terms of values and virtues.
Second, a review of relevant literature on leadership approaches and models consistent
with the CSR and sustainable entrepreneurship discourse is presented, emphasising the relationship between transformational, moral and virtues-based leadership and
CSR-oriented strategies and sustainable entrepreneurship. Drawing from the analysis,
four main propositions are introduced. The final sections illustrate the propositions and
summarise the implications and limitations of the study
The medieval forms and meanings of Francois: The political and cultural vicissitudes of an ethnonym
No full textThe article looks at the evolution of the ethnonym Francois in the Middle Ages and its significance to Germanic peoples known as Franks in the context of their cross-cultural relations with Muslim, Byzantine and British people. The author analyzes chronicles of the First Crusade and examines the use of Francois as an exonym and an autonym, and its role in the development of the French identity
Strategic management of population programs
No full textFormal strategic planning and management appear to contribute to organizational effectiveness. The author surveys the literature on strategic management in private/for-profit organizations and applies lessons from that literature to population programs. Few would argue that population programs would not benefit from strategic planning and management, but it would be inadvisable to initiate the process when the organization is faced with a short-term crisis; during or immediately before a change in leadership; or when implementation is unlikely. Public sector programs seem to have the latitude to manage strategically. Models available for adoption include life-cycle models, strategic issues management, stakeholder analysis, and portfolio analysis. The model selected may be a function of: (1) who will use it (life-cycle/evolutionary models may be well-suited to the planning needs of donors); (2) the presence of challenges to the survival of the program or to key components of it (stakeholder analysis would find ready application in those circumstances); and (3) the relative success and stability of the program (portfolio analysis may help a program balance its activities in a stable environment whereas strategic issues management is useful in responding to a dynamic environment.) It is important to marshall top-level support, designatewho will do the leg work, analyze the organization's history and current situation, assess internal strengths and weaknesses and external threats and opportunities, and summarize critical issues facing the program. Then a strategy may be developed. Among the available approaches are: (1) scenario developments (useful for a program that senses a need to change its approach to clients); (2) critical issues analysis (useful for refining successful programs); and (3) a goal approach (useful for programs with diffuse, ill-defined objectives). There are no short-cuts, it is argued. A strategic plan typically contains: (1) a mission statement that describes the social need to be addressed, what is unique about the organization, what its values are, and who the principal stakeholders are; (2) a statement of the population to be served and goals for service delivery and quality standards; (3) a service delivery strategy; (4) a financial strategy; (5) a marketing strategy; and (6) support strategies. Most organizations will find that there is no ideal structure - all require tradeoffs - and that attention should focus on eliminating patently dysfunctional aspects of the structure.Health Monitoring&Evaluation,ICT Policy and Strategies,Agricultural Knowledge&Information Systems,Educational Sciences,Enterprise Development&Reform
On Forecasting Dust Storms on Mars
No full textLuca Montabone, Space Science InstituteFrancois Forget, Laboratoire de Météorologid Dynamique, IPSL, CNRSICES510: Planetary and Spacecraft Dust Properties and Mitigation TechnologiesThe 48th International Conference on Environmental Systems was held in Albuquerque, New Mexico, USA on 08 July 2018 through 12 July 2018.Dust storms on Mars are the effect of strong and extended dust lifting by near-surface winds, and the behavior of dust clouds aloft both depends on and impacts the atmospheric circulation. The dust particles can represent a problem for surface mechanical and electrical systems as well as for the health and ground operation of future astronauts on the Red Planet.
The spatial and temporal distributions of dust aerosol are essential observables for any fundamental or applied study related to the Martian atmosphere, including weather monitoring and forecasting for robotic and future human exploration missions.
In this presentation we provide a review on the current and future capabilities of forecasting Martian dust storms. This includes the use of advanced techniques, such as the data assimilation of satellite observations, as well as the possibility of collecting novel observations, such as dust observations from the vantage point of view of a satellite in areostationary orbit (i.e. the Mars equivalent of a terrestrial geostationary orbit)
