The prefigurative politics of leadership education: Connecting our practice to broader movements.

Why develop leaders? What politics are implicit in our practice? This paper uses the history and practice of Popular Education as a comparative framework to survey the politics of intentional emergence leadership pedagogy, surfacing potential alliances for building social change movements. Using a case analysis, the article elucidates the ways the classroom embodies an opportunity to explore and enact a prefigurative politics of significant social change that upends traditional relationships to authority, hierarchy, and decision-making. Exploring the opportunities and dangers of connecting the classroom to broader social movements, the article concludes by advocating that such connections could offer a firmer and more explicit stance to the question: why develop leaders?

The classroom as laboratory: A theoretical grounding of the intentional emergence framework for leadership development.

Leadership development, like other professional areas such as medicine, teaching, and law, requires students to become as adept at practicing leadership as they are at understanding the theory behind it. For example, K-12 teachers have student teaching, medical students have residencies, cadavers, and virtual reality-but where is the learning laboratory for leadership? The intentional emergence (IE) pedagogy provides a framework for instructors and learners that both honors the role of the instructor as a goal/outcome-setter while also embracing the complexities of the leadership development space as a living laboratory and practice field for leadership. Additionally, IE attempts to bring unconscious and default behaviors to the foreground so that critical components of leadership development such as power, privilege, and identities can be seen and included.

Mesoporous Metastable CuTe2 Semiconductor.

Binary metastable semiconductor materials offer exciting possibilities in the field of optoelectronics, such as photovoltaics, tunable photosensors, and detectors. However, understanding their properties and translating them into practical applications can sometimes be challenging, owing to their thermodynamic instability. Herein, we report a temperature-controlled crystallization technique involving electrochemical deposition to produce metastable CuTe2 thin films that can reliably function under ambient conditions. A series of in situ heating/cooling cycle tests from room temperature to 200 °C followed by spectral, morphological, and compound analyses (such as ultraviolet-visible light spectroscopy, X-ray diffraction (XRD) analysis, and X-ray photoelectron spectroscopy (XPS)) suggest that the seeding electrodes play a key role in the realization of the metastable phase in CuTe2 films. In particular, CuTe2 films deposited on Al electrodes exhibit superior crystallinity and long-term stability compared with those grown on a Au substrate. The XRD data of thermally annealed CuTe2 thin films deposited on Al show a markedly sharp peak, indicating significantly increased crystal-domain sizes. Our method can be used to achieve the metastable phase of CuTe2 with a bandgap of 1.67 eV and offers outstanding photoresponsivity under different illumination conditions.

Shaping the Future of Health Data: A Scenario-Based Approach.

BACKGROUND: The European health care industry faces massive changes which impose new challenges on its stakeholders. OBJECTIVE: In this paper, we present the results of a market-based analysis for upcoming changes in the European health care industry and what this specifically means for issues corresponding to data. METHOD: Scenarios are a common tool to explain and analyze future changes in business environments. This method was used in a series of workshops together with an interdisciplinary group of experts. RESULTS: Ten individual scenarios represent potential futures with distinctive subsets of data landscapes. Their assessment shows that the expected future of health data is still rather unclear, while desired changes are quite distinct. CONCLUSION: The Health Data Scenarios offer a comprehensive framework for analyzing future data-driven developments in the health care industry.

Macroscopic behavior of ferrocholesteric liquid crystals and ferrocholesteric gels and elastomers.

We study the influence of macroscopic chirality on the macroscopic properties of superparamagnetic liquid crystals and gels. Specifically we derive macroscopic dynamic equations for ferrocholesteric low molecular weight (LMW) liquid crystals and for ferrocholesteric gels and elastomers in the local description using the director field as macroscopic variable. The magnetization is treated as a macroscopic dynamic degree of freedom and its coupling to all other macroscopic variables is examined in detail. We incorporate into our dynamic analysis terms that are linear in a magnetic field giving rise to a number of cross-coupling terms not possible otherwise. A number of properties that are unique to the class of systems studied arise. As an example for a static property we find a term in the generalized energy which is linear in the electric field and quadratic in the magnetic field. We find that applying a magnetic field to a ferrocholesteric can lead to reversible electric currents, heat currents and concentration currents, which change their sign with a sign change of macroscopic chirality. As an example of a rather intriguing dissipative dynamic contribution we point out that for ferrocholesterics and for ferrocholesteric gels and elastomers in a magnetic field extensional flow leads to electric and heat currents.

Reverse micelles dissolved in supercritical xenon: an NMR spectroscopic study.

Reverse micelles currently gain increasing interest in chemical technology. They also become important in biomolecular NMR due to their ability to host biomolecules such as proteins. In the present paper, a procedure for the preparation of high-pressure NMR samples containing reverse micelles dissolved in supercritical xenon is presented. These reverse micelles are formed by sodium bis(2-ethylhexyl) sulfosuccinate (AOT). For the first time, NMR spectroscopy could be applied to reverse micelles in supercritical xenon. The AOT/H(2)O/Xe system was studied as a function of experimental parameters such as xenon pressure, water content, and salt concentration. Optimum conditions for reverse micelle formation in supercritical xenon could be determined. It is, furthermore, demonstrated that biomolecules such as amino acids and proteins can be incorporated into the reverse micelles dissolved in supercritical xenon.
