A Qualitative Study of Redemptive Intelligence and the Leader’s Opportunity to Grow Performance Through Failure
This is a qualitative study about the redemptive intelligence of successful leaders and their opportunity to grow their personal and team performance through failure. Leaders who have a strong ability to leverage failures for improved performance for self and team, exhibit high levels of redemptive intelligence. Leaders who have a weak ability to leverage failures for improved performance for self and team, exhibit low levels of redemptive intelligence. After failure happens there are one of three paths that everyone will follow. They are first, a path to improved performance than what was experienced before the failure. Second, a return to normal levels of performance. Third, a path to lower levels of performance than what was experienced before the failure. From current literature and this study’s research of successful leaders from various industries, it was found that there are six common themes or phases of redemptive intelligence that impact the successfulness of the failure recovery process. These phases can happen in succession or in variable order. They are first, bravely acknowledge and process painful emotions with hope. Second, pause and reflect for lessons learned. Third, fix-it with humility and honesty. Fourth, grit through with purpose and perseverance. Fifth, forsake with faith and resolved confidence. Sixth, support with joyful optimism in self and others.
The study included 10 participants who were surveyed and interviewed. Success was defined by these participants along the lines of progression and joy. Failure was defined along the lines of pain and quitting. These definitions evolved over time and became less of a zero-sum game where they were focused on things and became more about learning and progression. Participants came from successful stints in various industry and ideology including government, politics, military, business, holistic health, law, homemaker, medicine, education, engineering, music, ecclesiastics, and athletics. Positions held by participants included Dean, Professor, CEO, Partner, Government Commissioner, Military Commander, Composer, Producer, Doctor, Surgeon, Lieutenant Colonel, Owner, Coach, Bishop/Pastor, Instructor, Lawyer, Teacher, Mother, Father, Missionary, Engineer, Founder, Board Chairman, Trainer, and President. Some of their accomplishments have included Researcher of the Year, expert surgeon, elite ranking in global business, National Champion, Founder of businesses and associations, Partner in company, Commander of elite leaders in military, Federal Commissioner, Parent, Grammy award winner, Vocal Group of the Year, Fellowship, and Doctoral degrees, etc. Participants were chosen for their common ability as proven and successful leaders
spacodiR: structuring of phylogenetic diversity in ecological communities
Motivation: spacodiR is a cross-platform package, written for the R environment, for studying partitioning of diversity among natural communities in space and time. Complementing and extending existing software, spacodiR allows for hypothesis testing and parameter estimation in studying spatial structuring of species-, phylogenetic- and trait diversities. Availability: Integrated with other software in the R environment and with well documented and demonstrated functions, spacodiR is an open-source package and available at http://cran.r-project.org.

Inference of evolutionary jumps in large phylogenies using LĂ©vy processes
Although it is now widely accepted that the rate of phenotypic evolution may not necessarily be constant across large phylogenies, the frequency and phylogenetic position of periods of rapid evolution remain unclear. In his highly influential view of evolution, G. G. Simpson supposed that such evolutionary jumps occur when organisms transition into so-called new adaptive zones, for instance after dispersal into a new geographic area, after rapid climatic changes, or following the appearance of an evolutionary novelty. Only recently, large, accurate and well calibrated phylogenies have become available that allow testing this hypothesis directly, yet inferring evolutionary jumps remains computationally very challenging. Here, we develop a computationally highly efficient algorithm to accurately infer the rate and strength of evolutionary jumps as well as their phylogenetic location. Following previous work we model evolutionary jumps as a compound process, but introduce a novel approach to sample jump configurations that does not require matrix inversions and thus naturally scales to large trees. We then make use of this development to infer evolutionary jumps in Anolis lizards and Loriinii parrots where we find strong signal for such jumps at the basis of clades that transitioned into new adaptive zones, just as postulated by Simpson’s hypothesis
Spitzer and z' Secondary Eclipse Observations of the Highly Irradiated Transiting Brown Dwarf KELT-1b
We present secondary eclipse observations of the highly irradiated transiting
brown dwarf KELT-1b. These observations represent the first constraints on the
atmospheric dynamics of a highly irradiated brown dwarf, and the atmospheres of
irradiated giant planets at high surface gravity. Using the Spitzer Space
Telescope, we measure secondary eclipse depths of 0.195+/-0.010% at 3.6um and
0.200+/-0.012% at 4.5um. We also find tentative evidence for the secondary
eclipse in the z' band with a depth of 0.049+/-0.023%. These measured eclipse
depths are most consistent with an atmosphere model in which there is a strong
substellar hotspot, implying that heat redistribution in the atmosphere of
KELT-1b is low. While models with a more mild hotspot or even with dayside heat
redistribution are only marginally disfavored, models with complete heat
redistribution are strongly ruled out. The eclipse depths also prefer an
atmosphere with no TiO inversion layer, although a model with TiO inversion is
permitted in the dayside heat redistribution case, and we consider the
possibility of a day-night TiO cold trap in this object. For the first time, we
compare the IRAC colors of brown dwarfs and hot Jupiters as a function of
effective temperature. Importantly, our measurements reveal that KELT-1b has a
[3.6]-[4.5] color of 0.07+/-0.11, identical to that of isolated brown dwarfs of
similarly high temperature. In contrast, hot Jupiters generally show redder
[3.6]-[4.5] colors of ~0.4, with a very large range from ~0 to ~1. Evidently,
despite being more similar to hot Jupiters than to isolated brown dwarfs in
terms of external forcing of the atmosphere by stellar insolation, KELT-1b has
an atmosphere most like that of other brown dwarfs. This suggests that surface
gravity is very important in controlling the atmospheric systems of substellar
mass bodies.Comment: 14 pages, 3 tables, 11 figures. Accepted by ApJ. Updated to reflect

Miniature exoplanet radial velocity array I: design, commissioning, and early photometric results
The MINiature Exoplanet Radial Velocity Array (MINERVA) is a US-based observational facility dedicated to the discovery and characterization of exoplanets around a nearby sample of bright stars. MINERVA employs a robotic array of four 0.7 m telescopes outfitted for both high-resolution spec- troscopy and photometry, and is designed for completely autonomous operation. The primary science program is a dedicated radial velocity survey and the secondary science objective is to obtain high precision transit light curves. The modular design of the facility and the flexibility of our hardware allows for both science programs to be pursued simultaneously, while the robotic control software provides a robust and efficient means to carry out nightly observations. In this article, we describe the design of MINERVA including major hardware components, software, and science goals. The telescopes and photometry cameras are characterized at our test facility on the Caltech campus in Pasadena, CA, and their on-sky performance is validated. New observations from our test facility demonstrate sub-mmag photometric precision of one of our radial velocity survey targets, and we present new transit observations and fits of WASP-52b—a known hot-Jupiter with an inflated radius and misaligned orbit. The process of relocating the MINERVA hardware to its final destination at the Fred Lawrence Whipple Observatory in southern Arizona has begun, and science operations are expected to commence within 2015
