Core Aspects of Dance: Schiller and Dewey on Grace

Part of a larger project of constructing a new, historically informed philosophy of dance, built on four phenomenological constructs that I call “Moves,” this essay concerns the third Move, “grace.” The etymology of the word “grace” reveals the entwined meanings of pleasing quality and authoritative power, which may be combined as “beautiful force.” I examine the treatments of grace in German philosopher Friedrich Schiller, who understands it as playful, naive transformation of matter; and in American philosopher John Dewey, for whom it represents rhythmic organism/environment reversal. I conclude by showing how “grace” can be used in analyzing various types of dance, which in turn suggests transformational potential for philosophy, dance, and society as a whole

Hysteretic behavior of the vortex lattice at the onset of the second peak for HgBa2_2CuO4+δ_{4+\delta} superconductor

By means of local Hall probe ac and dc permeability measurements we investigated the phase diagram of vortex matter for the HgBa$_2$CuO$_{4+\delta }$ superconductor in the regime near the critical temperature. The second peak line, $H_{\rm sp}$, in contrast to what is usually assumed, doesn't terminate at the critical temperature. Our local ac permeability measurements revealed pronounced hysteretic behavior and thermomagnetic history effects near the onset of the second peak, giving evidence for a phase transition of vortex matter from an ordered qausilattice state to a disordered glass

Time Dependent Effects and Transport Evidence for Phase Separation in La_{0.5}Ca_{0.5}MnO_{3}

The ground state of La_{1-x}Ca_{x}MnO_{3} changes from a ferromagnetic metallic to an antiferromagnetic charge-ordered state as a function of Ca concentration at x ~ 0.50. We present evidence from transport measurements on a sample with x = 0.50 that the two phases can coexist, in agreement with other observations of phase separation in these materials. We also observe that, by applying and then removing a magnetic field to the mainly charge-ordered state at some temperatures, we can "magnetically anneal" the charge order, resulting in a higher zero-field resistivity. We also observe logarithmic time dependence in both resistivity and magnetization after a field sweep at low temperatures.Comment: 9 pages, LATEX, 3 postscript figure

Crystal and magnetic structure of the La1−x_{1-x}Cax_{x}MnO3_{3} compound (x=0.8,0.85)(x=0.8,0.85)

We studied the crystal and magnetic structure of the La$_{1-x}$Ca$_{x}$MnO$_{3}$ compound for $x=0.8$ and $x=0.85$. At T=300 K both samples are paramagnetic with crystallographic symmetry $Pnma$. At low temperatures they undergo a monoclinic distortion from orthorhombic $Pnma$-type structure with $a_p\sqrt{2}\times 2a_p\times a_p\sqrt{2}$ to a monoclinic structure with ($a_p\sqrt{2}\times 2a_p\times a_p\sqrt{2}$, $\beta=90+\epsilon\sim 91.4^{\rm o}$) and $P2_1/m$ space group below $T_N$. The onset of the structural transformation coincides with the development of the $C$-type long range antiferromagnetic order with propagation vector ${\bf k}=({1/2},0,{1/2})$. The monoclinic unit cell allowed us to determine the direction of the Mn magnetic moment with respect to the crystallographic axes: it is perpendicular to the propagation vector, ${\bf m}\perp {\bf k}=({1/2},0,{1/2})$. The amplitude of the ordered magnetic moment at $T=1.6$ K is found to be $2.53(2)$ and $2.47(2)\mu_{B}$ for $x=0.8$ and 0.85, respectively.Comment: In press (Phys. Rev B 01 Feb 2002

Management earnings forecast and IPO performance: Evidence of a regime change

Companies making initial public offerings (IPOs) in Greece were obliged to include next-year profit forecast in their prospectuses until the regulation changed in 2001 to voluntary disclosure. This research takes advantage of these two regulatory regimes to study the long-term performance of 303 IPOs issued during January 1993– December 2014over 36 months of secondary-market performance. Findings indicate behavioral change, as positive long term (three-year) return during the mandatory era turned negative in the voluntary period. Comparison of these two regimes may suggest that a mandatory regulatory environment in which firms are forced to provide earnings forecasts delivers better investor returns. On the contrary, the results reveal that a regulation that penalizesing IPO firms for providing what are necessarily highly inaccurate earnings forecasts affects long-term returns because it creates an insecure investment environment. Additional analysis shows that Opportunities for good long-term performance is higher mprove for IPOs under a mandatory earnings regime during a “cold” period with low given ownership and high oversubscription. It is noteworthy that lack of experience and high associated costs prevent a number of IPO firms from providing earnings forecasts under the voluntary regime

Why local banking market concentration hinders IPOs and how it can work to issuers’ advantage

General sample evidence conceals the influence of banking market structure on a fraction of IPO issuers with limited financing options: small non-venture-capital-backed firms (SNVC). Using U.S. county-level data, we reveal that concentrated banking markets contract IPO activity, as they cause SNVCs to incur high underpricing at listing. However, when the size of the local banks is small, both the time to IPO and underpricing decrease. Our evidence infers that, unless banks are organizationally capable of tapping into soft information, they generally use market power for rent extraction, which has important spillover effects on the IPO market.PostprintPeer reviewe
