"All Shook Up" at the parkes elvis festival: The role of play in events

© 2015 Cognizant Comm. Corp. Leisure in the postmodern environment is often regarded as superficial, depthless, and meaningless, dominated by simulation and hyperreality. Many aspects of the Parkes Elvis Festival fall clearly into the category of simulation and hyperreality as attendees imitate Elvis Presley (and other associated characters) and are willing to accept the fake and contrived as real. However, the simulation does not, in the case of the Parkes Elvis Festival, lead to a depthless, meaningless, or inauthentic experience. Using Huizinga's ideas of play and Bateson's play frame we present the Elvis Festival as a liminal social space that invites playfulness and creativity. The theory of Georg Simmel is explored to show how sociability is created at the event to facilitate play. Finally, Csikszentmihalyi's theory of flow is used to demonstrate ways in which the enjoyment of the playful event experience is maximized for participants. We argue that play provides the substance that makes the Parkes Elvis Festival memorable and meaningful. An understanding of play theory may assist event managers to increase social facilitation at festivals and events, ensuring an enjoyable, sociable, creative, and authentic experience for attendees

Non-Fermi liquid angle resolved photoemission lineshapes of Li0.9Mo6O17

A recent letter by Xue et al. (PRL v.83, 1235 ('99)) reports a Fermi-Liquid (FL) angle resolved photoemission (ARPES) lineshape for quasi one-dimensional Li0.9Mo6O17, contradicting our report (PRL v.82, 2540 ('99)) of a non-FL lineshape in this material. Xue et al. attributed the difference to the improved angle resolution. In this comment, we point out that this reasoning is flawed. Rather, we find that their data have fundamental differences from other ARPES results and also band theory.Comment: To be published as a PRL Commen

New Luttinger liquid physics from photoemission on Li0.9_{0.9}Mo6_6O17_{17}

Temperature dependent high resolution photoemission spectra of quasi-1 dimensional Li$_{0.9}$Mo$_6$O$_{17}$ evince a strong renormalization of its Luttinger liquid density-of-states anomalous exponent. We trace this new effect to interacting charge neutral critical modes that emerge naturally from the two-band nature of the material. Li$_{0.9}$Mo$_6$O$_{17}$ is shown thereby to be a paradigm material that is capable of revealing new Luttinger physics.Comment: 4 pages, 3 figures. Accepted for publication by Phys. Rev. Let

Photoemission view of electron fractionalization in quasi-one dimensional metal Li0.9_{0.9}Mo6_6O17_{17}

We report Luttinger liquid line shapes better revealed by new angle resolved photoemission data taken with a much improved angle resolution on a quasi-1-dimensional metal Li$_{0.9}$Mo$_6$O$_{17}$. The new data indicate a larger spinon velocity than our previous lower resolution data indicated.Comment: submitted to SCES '0

114 Years and Counting – An Updated History of the University of South Dakota Sanford School of Medicine

If those who founded the USD Sanford School of Medicine in 1907 were to drop in on the school today, what would they find most surprising? Would the time travelers marvel at the modern teaching facilities, our amazing ability to cure previously deadly diseases, or would they be puzzled by the complexities of medical practice in the modern era of technology and regulation? The first century of the medical school’s existence brought immense change as the school evolved. As advances in medical science and medical practice accelerated, the school kept pace. The first century resulted in a well-established medical school that provided excellent education and supplied an outstanding medical workforce for South Dakota. Now more than a dozen years into its second century, the school has moved squarely into the national spotlight. As the following article details, the school has become an award-winning leader in curricular innovation, setting the standard for longitudinally integrated learning. New rural-based programs have drawn students to the wonderful small towns of South Dakota for a deep and meaningful educational experience. Basic science research has blossomed, bringing important discoveries and opening opportunities for students. New residency programs have been developed to train graduating students. The school has deepened its commitment to serve all the diverse communities of the state. Most recently, a new focus on kindness in medicine has emerged. Yet if visitors from 1907 found much to surprise them, there is much that would seem unchanged. The school still needs, receives and is very grateful for the support it receives from the physicians, healthcare institutions, leaders, and communities of South Dakota. Faculty and students are still known for their integrity, skill and hard work. The unwavering focus on educational excellence and providing a physician workforce for South Dakota continues. The advances of today are built on the foundations of yesterday. The pace of change is always increasing. Imagine the possibilities

Luttinger liquid ARPES spectra from samples of Li0.9_{0.9}Mo6_6O17_{17} grown by the temperature gradient flux technique

Angle resolved photoemission spectroscopy line shapes measured for quasi-one-dimensional Li$_{0.9}$Mo$_6$O$_{17}$ samples grown by a temperature gradient flux technique are found to show Luttinger liquid behavior, consistent with all previous data by us and other workers obtained from samples grown by the electrolyte reduction technique. This result eliminates the sample growth method as a possible origin of considerable differences in photoemission data reported in previous studies of Li$_{0.9}$Mo$_6$O$_{17}$.Comment: Some text adde

Non-fermi-liquid single particle lineshape of the quasi-one-dimensional non-CDW metal Li_{0.9}Mo_{6}O_{17} : comparison to the Luttinger liquid

We report the detailed non-Fermi liquid (NFL) lineshape of the dispersing excitation which defines the Fermi surface (FS) for quasi-one-dimensional Li_{0.9}Mo_{6}O_{17}. The properties of Li_{0.9}Mo_{6}O_{17} strongly suggest that the NFL behavior has a purely electronic origin. Relative to the theoretical Luttinger liquid lineshape, we identify significant similarities, but also important differences.Comment: 5 pages, 3 eps figure

Polyethylene glycol-coated collagen patch (hemopatch®) in open partial nephrectomy

PURPOSE To describe the results of a polyethylene glycol-coated collagen patch, Hemopatch® on blood loss, surgical time and renal function in partial nephrectomy (PN) for renal cell carcinoma (RCC). METHODS Out of a single surgeon cohort of n = 565 patients undergoing conventional open PN (CPN) between 01/2015 and 12/2017 at the University of Munich a consecutive subgroup (n = 42) was operated on using a polyethylene glycol-coated collagen-based sealant Hemopatch® (Baxter International Inc., Deerfield, IL, USA) (HPN). RESULTS Median age was 65.2~years (range 12.7-95.2) with median follow-up of 9.43~months (0.03-49.15). Baseline renal function (CKD-EPI) was 78.56~ml/min/1.73~m2 (range 20.38-143.09) with a non-significant decline to 74.78~ml/min/1.73~m2 (range 3.75-167.74) at follow-up. In CPN 46% had low complexity, 33% moderate complexity and 20% high complexity lesions with 33% low, 40% moderate and 27% high complexity masses in HPN. Median tumor size was 4.3~cm (range 1-38~cm) in CPN with 4.8~cm (range 3.8-18.3~cm) with HPN, p = 0.293. Median blood loss and duration of surgery was significantly lower in the HPN group vs. CPN (146~ml ± 195 vs. 114~ml ± 159~ml; p = 0.021; 43~min ± 27 for HPN vs. 53~min ± 49; p = 0.035) with no difference in clamping time (12.6~min ± 8.6 for HPN vs. 12.0~min ± 9.5; p = 0.701). CONCLUSIONS Hemopatch® supported renoraphy shows promising results compared to standard renoraphy in PN. No side effects were seen. Further studies should evaluate the prevention of arterio-venous or urinary fistulas. In complex partial nephrectomies Hemopatch® supported renoraphy should be considered

Two-dimensional Hubbard-Holstein bipolaron

We present a diagrammatic Monte Carlo study of the properties of the Hubbard-Holstein bipolaron on a two-dimensional square lattice. With a small Coulomb repulsion, U, and with increasing electron-phonon interaction, and when reaching a value about two times smaller than the one corresponding to the transition of light polaron to heavy polaron, the system suffers a sharp transition from a state formed by two weakly bound light polarons to a heavy, strongly bound on-site bipolaron. Aside from this rather conventional bipolaron a new bipolaron state is found for large U at intermediate and large electron-phonon coupling, corresponding to two polarons bound on nearest-neighbor sites. We discuss both the properties of the different bipolaron states and the transition from one state to another. We present a phase diagram in parameter space defined by the electron-phonon coupling and U. Our numerical method does not use any artificial approximation and can be easily modified to other bipolaron models with longer range electron-phonon and/or electron-electron interaction.Comment: 14 pages, 12 figure
