Developing Whole Leaders for the Whole World
How do we holistically develop leaders with the capacity and character to tackle the most pressing moral challenges in our modern world? While it may be easier to focus on one thing such as strengths, experiences, or mentors, the reality is that developing a leader’s capacity to lead well includes many interrelated components. Based on our experience and research, the six components of the Holistic Leadership Development Model (HLDM) are presented, along with strategies for creating rich conversations that connect the components in a meaningful way for leaders. The six areas are (1) experiences and learning; (2) strategic networking; (3) developing others; (4) integrated fulfillment; (5) leading under pressure; and (6) calling and purpose. While we are not suggesting that these are the only areas to consider when developing leaders, focusing on these six creates conversations and development plans for leaders that they perceive as capturing the reality of the challenges they face in developing their leadership capacity. Guides for evaluating one’s own leadership development and for having rich development conversations are included
THE FOURTH COLOUR FILTER OF TRISTIMULUS COLORIMETERS
We have proved that the application of the tristimulus value Xz seems to be unnecessary.
It can be suggested that the measuring of the tristimulus value Xz should be left and the sign X2
should be defined from the measured value Z on the base of the following connection:
Z
X.",,--

It would be more proper to neglect the use of the tristirnulus value X2 but this would need the total
reconstructing of the CIE colour-system
The Scaling Behaviour of Stochastic Minimization Algorithms in a Perfect Funnel Landscape
We determined scaling laws for the numerical effort to find the optimal configurations of a simple model potential energy surface (PES) with a perfect funnel structure that reflects key characteristics of the protein interactions. Generalized Monte-Carlo methods(MCM, STUN) avoid an enumerative search of the PES and thus provide a natural resolution of the Levinthal paradox. We find that the computational effort grows with approximately the eighth power of the system size for MCM and STUN, while a genetic algorithm was found to scale exponentially. The scaling behaviour of a derived lattice model is also rationalized
Building and Sustaining Hope in the Face of Failure: Understanding the Role of Strategic Social Support
The research on hope has focused on how individuals build and maintain hopeful emotions through their own successful attempts of achieving their goals using personal agency and pathways. Success in meeting the goal leads to higher levels of hope within an individual and an increased belief that they can achieve more difficult tasks, while failure leads to a decrease in levels of hope (Helland & Winston, 2005; Snyder, Rand, & Sigmon, 2002; Snyder, Shorey, Cheavens, Pulvers, Adams, & Wiklund, 2002; Snyder, Irving, & Anderson, 1991). The purpose of this study was to explore the moderating relationship of strategic social support on levels of hope despite ratings of experience with failure. The sample was sourced from participants in an online leadership development tool. Once outliers were removed and missing data was managed through multiple imputation, the final sample for this study was 573. The age range was 21 to 97 with 56.2% identifying as female. Moderation analyses were conducted using PROCESS macro for SPSS (Model 1 and Model 2). While interaction effects were insignificant, main effects for social support on levels of hope were significant (B = 0.154, p = .007). Furthermore, there was a significant main effect of relational strategic social support (emotional support, advocates, and sources of feedback) on levels of hope (B = 0.141, p = .05). Additional exploratory analyses found that both sources of feedback (B = 0.141, p = .000) and advocates (B = 0.121, p = .0184) had significant main effects on hope when assessed separately. The results of this study indicate that strategic social support may have a key role to play in building and sustaining levels of hope and be worth the investment and effort to connect individuals with the sources of support they need to increase levels of hope
Low energy proton bidirectional anisotropies and their relation to transient interplanetary magnetic structures: ISEE-3 observations
It is known that the interplanetary medium in the period approaching solar maximum is characterized by an enhancement in the occurrence of transient solar wind streams and shocks and that such systems are often associated with looplike magnetic structures or clouds. There is observational evidence that bidirectional, field aligned flows of low energy particles could be a signature of such looplike structures, although detailed models for the magnetic field configuration and injection mechanisms do not exist at the current time. Preliminary results of a survey of low energy proton bidirectional anisotropies measured on ISEE-3 in the interplanetary medium between August 1978 and May 1982, together with magnetic field data from the same spacecraft are presented
Virtual acoustics displays
The real time acoustic display capabilities are described which were developed for the Virtual Environment Workstation (VIEW) Project at NASA-Ames. The acoustic display is capable of generating localized acoustic cues in real time over headphones. An auditory symbology, a related collection of representational auditory 'objects' or 'icons', can be designed using ACE (Auditory Cue Editor), which links both discrete and continuously varying acoustic parameters with information or events in the display. During a given display scenario, the symbology can be dynamically coordinated in real time with 3-D visual objects, speech, and gestural displays. The types of displays feasible with the system range from simple warnings and alarms to the acoustic representation of multidimensional data or events
Evidence of columnar order in the fully frustrated transverse field Ising model on the square lattice
Using extensive classical and quantum Monte Carlo simulations, we investigate
the ground-state phase diagram of the fully frustrated transverse field Ising
model on the square lattice. We show that pure columnar order develops in the
low-field phase above a surprisingly large length scale, below which an
effective U(1) symmetry is present. The same conclusion applies to the Quantum
Dimer Model with purely kinetic energy, to which the model reduces in the
zero-field limit, as well as to the stacked classical version of the model. By
contrast, the 2D classical version of the model is shown to develop plaquette
order. Semiclassical arguments show that the transition from plaquette to
columnar order is a consequence of quantum fluctuations.Comment: 5 pages (including Supplemental Material), 5 figure
