description: We conduct a field study on a prominent US health insurance firm to examine the cost saving rationale for deploying self service at the call centers. In our setting, firm introduced web self-service portal for its members to contain large telephone handling cost at its call center. Management Practitioners claim that per interaction cost of web based self service channel is an order of magnitude cheaper than the assisted channels of customer service like telephony. However, they do not account for the impact of web based self service usage on the demand for other assisted channels. Surprisingly, the net effect of web based self service on other assisted channels of customer service has not been empirically validated so far. Drawing from the vertical differentiation literature in economics and human information acquisition and processing theories from psychology, we present a theoretical framework to show that both possibilities may exist (1) the web based self-service substitutes the assisted channels and (2) web based self-service leads to increase in demand for assisted channel. In our field setting, we show through a robust diff-in-diff specification that web based self service usage leads to 23% increase in telephony usage. We also use instrumental variables to account for potential selection of customers into the self service usage. Our results inform practicing managers on many counts (1) although cheaper on per interaction level, web based self-service may not be necessarily cheaper overall (2) Need for integrated management in multichannel customer service setup e.g. web based self service should have an option for escalating the query to other assisted channels (3) Self services should not be seen only as a mean for reducing operational cost, as it provides wider options to customers that may lead to higher customer satisfaction and loyalty.
title: El “genio de las ruinas”: indagaciones sobre los orígenes de la silva “Atenas y Palmira” de José María Heredia

description: Entre los poemas de José María Heredia (Cuba 1803-México 1839) hay varios que tratan el tema del viajero que medita ante las ruinas de civilizaciones desaparecidas. El más conocido y estudiado de este grupo es “En el teocalli de Cholula,” una silva que el cubano probablemente esbozó al visitar Cholula durante su primera estadía en México (1819-1820).1 Bajo el título “Fragmentos descriptivos de un poema mexicano,” el poema vio la luz en forma truncada en la primera edición de las Poesías (1825) que Heredia publicó en Nueva York durante su exilio estadounidense. Volvió a aparecer en la edición de sus Poesías de Toluca de 1832, en su forma completa y con el título con que es conocido desde entonces. El poema evoca la “muda y desierta” pirámide cholulteca, reliquia de la cultura azteca cuyas “glorias” están “engolfadas y perdidas / en la profunda noche de los tiempos.” Propone que la pirámide ofrece una “lección saludable” sobre la vanidad de los alardes de poder de los déspotas, y de “la demencia y del furor humano” en general (Poesías del ciudadano 2, 41- 42).

description: Intensive Care Unit (ICU) is a highly stressful and unique environment. Caring for a diverse client population requires nurses effective communication and empathy. These traits, in turn, help to improve patient care and outcomes, increase the level of patient satisfaction, and decrease adverse events. These also promote effective decision making, problem-solving, and encourage good collaboration with fellow health workers. The purpose of the present study is to determine the relationship between Communication Competence and Empathy among Nurses in the Intensive Care Unit of Tertiary Hospital in Saudi Arabia.   The respondents consisted of 243 ICU nurses, and the tools used were a Self -Perceived Communication Competence Scale and Toronto Empathy Questionnaire. Descriptive correlational statistics were used to analyze the data. Results revealed that the Self-Perceived Communication Competence among nurses in the ICU is High in contexts such as in public and in group with strangers, friends and acquaintances; and the nurses have high level of empathy. It was also revealed in the results that level of communication competence and level of empathy have no significant relationship. However, the level of communication  competence is significantly linked to educational attainment of nurses; while the level of empathy is significantly correlated to age ,  nationality and length of experience of the nurses.

description: The effective diffusivity $D_e$ of tracer particles diffusing in periodically corrugated axisymmetric two and three dimensional channels is studied. The majority of previous studies of this class of problems are based on perturbative analyses about narrow channels, where the problem can be reduced to an effectively one dimensional one. Here we show how to analyze this class of problems using a much more general approach which even includes the limit of infinitely wide channels. Using the narrow and wide channel asymptotics, we provide a Pad{é} approximant scheme that is able to describe the dispersion properties of a wide class of channels. Furthermore, we systematically identify all the exact asymptotic scaling regimes of $D_e$ and the accompanying physical mechanisms that control dispersion, clarifying the distinction between smooth channels and compartmentalized ones, and identifying the regimes in which $D_e$ can be linked to first passage problems.

description: The millimeter wavelength emission from GRB 991208 is the second brightest ever detected, yielding a unique data set. We present here well-sampled spectra and light curves over more than two decades in frequency for a two-week period. This data set has allowed us for the first time to trace the evolution of the characteristic synchrotron self-absorption frequency nu_a and peak frequency nu_m, and the peak flux density F_m: we obtain nu_a \propto t^{-0.15 +- 0.12}, nu_m \propto t^{-1.7 +- 0.4}, and $_m \propto t^{-0.47 +- 0.11}. From the radio data we find that models of homogeneous or wind-generated ambient media with a spherically symmetric outflow can be ruled out. A model in which the relativistic outflow is collimated (a jet) can account for the observed evolution of the synchrotron parameters, the rapid decay at optical wavelengths, and the observed radio to optical spectral flux distributions that we present here, provided that the jet transition has not been fully completed in the first two weeks after the event. These observations provide additional evidence that rapidly decaying optical/X-ray afterglows are due to jets and that such transitions either develop very slowly or perhaps never reach the predicted asymptotic decay F(t) \propto t^{-p}.

description: Using the entropy function formalism we compute the entropy of extremal supersymmetric and non-supersymmetric black holes in N=2 supergravity theories in four dimensions with higher derivative corrections. For supersymmetric black holes our results agree with all previous analysis. However in some examples where the four dimensional theory is expected to arise from the dimensional reduction of a five dimensional theory, there is an apparent disagreement between our results for non-supersymmetric black holes and those obtained by using the five dimensional description. This indicates that for these theories supersymmetrization of the curvature squared term in four dimension does not produce all the terms which would come from the dimensional reduction of a five dimensional action with curvature squared terms.

description: We use the density functional perturbation theory to determine for the first time the pressure evolution of the Raman intensities for a mineral, the two high-pressure structures of MgSiO3 perovskite and post-perovskite. At high pressures, the Raman powder spectra reveals three main peaks for the perovskite structure and one main peak for the post-perovskite structure. Due to the large differences in the spectra of the two phases Raman spectroscopy can be used as a good experimental indication of the phase transition.

description: Ultrafast lasers have revolutionized material processing, opening a wealth of new applications in many areas of science. A recent technology that allows the cleaving of transparent materials via non-ablative processes is based on focusing and translating a high-intensity laser beam within a material to induce a well-defined internal stress plane. This then enables material separation without debris generation. Here, we use a non-diffracting beam engineered to have a transverse elliptical spatial profile to generate high aspect ratio elliptical channels in glass of dimension 350 nm x 710 nm, and subsequent cleaved surface uniformity at the sub-micron level.

description: The adsorption of two-dimensional (2-D) graphene oxide (GO) nanosheets at the air-water interface has broad technological implications for GO-based functional material preparations. Molecular-level understanding of the adsorption mechanism and interfacial behaviour is of great significance. Here, the adsorption free energy of GO nanosheets at the air-water interface was simulated, in which the effect of functional groups and deprotonation has been investigated. It was observed that the neutral GOs are generally thermodynamically favourable for the interface adsorption, while the deprotonated GO sheet has no such interface activity. Although the carboxyl group can enhance the interface adsorption minimum in the free energy profile, thereby improving the interfacial activity of the GO sheet, the oxidisation degree on GO is the main controlling factor determining the interface affinity. The interfacial morphology and dynamics of GO nanosheets have also been simulated, in which a parallel movement with a 2-D anisotropic rotation along the interface was revealed. Our simulation results provide new insights into the adsorption mechanism and behaviour of GO at the air-water interface.

description: Knowledge of building science – how buildings perform with respect to energy efficiency, durability, comfort, and health – is a key aspect of sustainable architectural design. Although most building science courses are taught in a traditional lecture format, experiential teaching methods have the potential to improve student engagement and comprehension of technical subject matter. This paper describes a case study of experiential learning in building science education. In Spring, 2018, we conducted a thermal comfort study as part of an integrated design studio at Pratt Institute in Brooklyn, NY. We measured temperature and relative humidity in the studio space and asked students about their thermal comfort via daily, point-in-time surveys. We analyzed the sensor results using the PMV model, finding that the majority of the studio (87% of sensor locations) was within the comfort zone (PMV between -0.5 and +0.5) during the study period. Students’ average reported thermal sensation over the same period (AMV, or actual mean vote) was -0.46, a result that suggested cold discomfort. The discrepancy between PMV and AMV suggests that factors not measured in this study – such as mean radiant temperature or air speed – may have negatively impacted students’ comfort. This case study suggests the potential for integrating hands-on building science investigations into technical architecture courses. Areas for improvement include tighter integration of these investigations into individual courses and the broader architecture curriculum to achieve the greatest impact on student engagement and learning

This is an order of magnitude improvement in precision over that from the use of pion-nuclear scattering data and dispersion relations.

description: We propose a mechanism for the origin of the Galactic ridge X-ray background that naturally explains the properties of the Fe K line, specifically the detection of the centroid line energy below 6.7 keV and the apparent broadness of the line. Motivated by recent evidence of nonthermal components in the spectrum of the Galactic X-ray/gamma-ray background, we consider a model that is a mixture of thermal plasma components of perhaps supernova origin and nonthermal emission from the interaction of low energy Cosmic ray electrons (LECRe) with the interstellar medium. The LECRe may be accelerated in supernova explosions or by ambient interstellar plasma turbulence. Atomic collisions of fast electrons produce characteristic nonthermal, narrow X-ray emission lines that can explain the complex Galactic background spectrum. Using the ASCA GIS archival data from the Scutum arm region, we show that a two-temperature thermal plasma model with kT~0.6 and ~2.8 keV, plus a LECRe component models the data satisfactorily. Our analysis rules out a purely nonthermal origin for the emission. It also rules out a significant contribution from low energy Cosmic ray ions, because their nonthermal X-ray production would be accompanied by a nuclear gamma-ray line diffuse emission exceeding the upper limits obtained using OSSE, as well as by an excessive Galaxy-wide Be production rate. The proposed model naturally explains the observed complex line features and removes the difficulties associated with previous interpretations of the data which evoked a very hot thermal component (kT~7 keV).

description: High pressure Raman experiments on Boron Nitride multi-walled nanotubes show that the intensity of the vibrational mode at ~ 1367 cm-1 vanishes at ~ 12 GPa and it does not recover under decompression. In comparison, the high pressure Raman experiments on hexagonal Boron Nitride show a clear signature of a phase transition from hexagonal to wurtzite at ~ 13 GPa which is reversible on decompression. These results are contrasted with the pressure behavior of carbon nanotubes and graphite.

description: We have investigated the role of proton-neutron pairing in the context of the Quasiparticle Random Phase approximation formalism. This way the neutrinoless double beta decay matrix elements of the experimentally interesting A= 48, 76, 82, 96, 100, 116, 128, 130 and 136 systems have been calculated. We have found that the inclusion of proton-neutron pairing influences the neutrinoless double beta decay rates significantly, in all cases allowing for larger values of the expectation value of light neutrino masses. Using the best presently available experimental limits on the half life-time of neutrinoless double beta decay we have extracted the limits on lepton number violating parameters.

description: Let $G$ be a graph with $n$ vertices, and let $A(G)$ and $D(G)$ denote respectively the adjacency matrix and the degree matrix of $G$. Define $$ A_α(G)=αD(G)+(1-α)A(G) $$ for any real $α\in [0,1]$. The $A_α$-characteristic polynomial of $G$ is defined to be $$ \det(xI_n-A_α(G))=\sum_jc_{αj}(G)x^{n-j}, $$ where $\det(*)$ denotes the determinant of $*$, and $I_n$ is the identity matrix of size $n$. The $A_α$-spectrum of $G$ consists of all roots of the $A_α$-characteristic polynomial of $G$. A graph $G$ is said to be determined by its $A_α$-spectrum if all graphs having the same $A_α$-spectrum as $G$ are isomorphic to $G$. In this paper, we first formulate the first four coefficients $c_{α0}(G)$, $c_{α1}(G)$, $c_{α2}(G)$ and $c_{α3}(G)$ of the $A_α$-characteristic polynomial of $G$. And then, we observe that $A_α$-spectra are much efficient for us to distinguish graphs, by enumerating the $A_α$-characteristic polynomials for all graphs on at most 10 vertices. To verify this observation, we characterize some graphs determined by their $A_α$-spectra.

description: Según refiere Margarita Giesecke Sara Laffose, para Juan de Arona, un intelectual peruano del siglo XIX, escribir era “cosa de hombres” (42). Su postura no era la excepción sino la norma en el Perú finisecular. El Club Literario de Lima, por ejemplo, no permitió el ingreso de mujeres hasta 1875, año en el que ofreció una fiesta en honor de Juana Manuela Gorriti, una escritora argentina que retornaba a su patria tras haber vivido casi por cuatro décadas en Lima. Gorriti fue la “madre literaria” (en palabras de Ana Peluffo) de Teresa González de Fanning (1836–1918), Carolina Freire de Jaimes (1844–1916), Lastenia Larriva de Llona (1848–1924), Clorinda Matto de Turner (1852– 1909) y Mercedes Cabello de Carbonera (1842–1909), entre otras cuantas escritoras peruanas. En este trabajo me ocuparé de Cabello, quien, en mi opinión, estaba predestinada a fracasar en su tiempo desde que se inició como escritora, en 1874, debido al discurso iconoclasta que siempre la caracterizó, y no como se piensa comúnmente, a partir de la publicación de su novela Blanca Sol (1888).

description: We present a study of elastic metamaterial that possesses multiple local resonances. We demonstrated that the elastic metamaterial can have simultaneously three negative effective parameters, i.e., negative effective mass, effective bulk modulus and effective shear modulus at a certain frequency range. Through the analysis of the resonant field, it has been elucidated that the three negative parameters are induced by dipolar, monopolar and quadrupolar resonance respectively. The dipolar and monopolar resonances result into the negative band for longitudinal waves, while the dipolar and quadrupolar resonances cause the negative band for transverse waves. The two bands have an overlapping frequency regime. A simultaneously negative refraction for both longitudinal waves and transverse waves has been demonstrated in the system.

description: We examine the evolving structure of the U.S. hospital industry since 1970, focusing on how ownership form influences entry and exit behavior. We develop theoretical predictions based on the model of Lakdawalla and Philipson, in which for-profit and not-for-profit hospitals differ regarding their objectives and costs of capital. The model predicts for-profits would be quicker to enter and exit than not-for-profits in response to changing market conditions. We test this hypothesis using data for all U.S. hospitals from 1984 through 2000. Examining annual and regional entry and exit rates, for-profit hospitals consistently have higher entry and exit rates than not-for-profits. Econometric modeling of entry and exit rates yields similar patterns. Estimates of an ordered probit model of entry indicate that entry is more responsive to demand changes for for-profit than not-for-profit hospitals. Estimates of a discrete hazard model for exit similarly indicate that negative demand shifts increase the probability of exit more for for-profits than not-for-profits. Finally, membership in a hospital chain significantly decreases the probability of exit for for-profits, but not not-for-profits.

Creators: name: Manzari, H. J.
Publisher: name: Utah State University
Year: 2006

description: Reinaldo Arenas’s La Loma del Ángel, published in the United States in 1987, represents one of a number of novels written by Cuban writers in exile, and yet, it is of particular importance with regard to the comparative study of the postmodern Caribbean narrative and the nineteenth-century Cuban costumbrista novel. La Loma appeared seven years after the young author left Cuba along with some 120,000 exiles that took part in the Mariel boat lift. Having lived the majority of his life under the Castro regime and finding himself imprisoned for his creative zeal, homosexuality, and ambition, the author’s life parallels many aspects of other Cuban exile writers but in particular, Cirilo Villaverde. The two authors were born in the countryside of Cuba and both writers were profoundly engaged in political and cultural changes in their respective periods of historical crisis. They suffered the trauma of prison and fled Cuba, by way of the sea, to Florida and eventually to New York. In New York, Villaverde rewrote and completed the definitive edition of Cecilia Valdés, while a century later Arenas comprised his own version of Villaverde’s masterpiece.

description: The goal of this paper is to propose novel strategies for adaptive learning of signals defined over graphs, which are observed over a (randomly time-varying) subset of vertices. We recast two classical adaptive algorithms in the graph signal processing framework, namely, the least mean squares (LMS) and the recursive least squares (RLS) adaptive estimation strategies. For both methods, a detailed mean-square analysis illustrates the effect of random sampling on the adaptive reconstruction capability and the steady-state performance. Then, several probabilistic sampling strategies are proposed to design the sampling probability at each node in the graph, with the aim of optimizing the tradeoff between steady-state performance, graph sampling rate, and convergence rate of the adaptive algorithms. Finally, a distributed RLS strategy is derived and is shown to be convergent to its centralized counterpart. Numerical simulations carried out over both synthetic and real data illustrate the good performance of the proposed sampling and reconstruction strategies for (possibly distributed) adaptive learning of signals defined over graphs.

description: We observe a thermally induced spontaneous magnetization reversal of epitaxial ferromagnet/antiferromagnet heterostructures under a constant applied magnetic field. Unlike any other magnetic system, the magnetization spontaneously reverses, aligning anti-parallel to an applied field with decreasing temperature. We show that this unusual phenomenon is caused by the interfacial antiferromagnetic coupling overcoming the Zeeman energy of the ferromagnet. A significant temperature hysteresis exists, whose height and width can be tuned by the field applied during thermal cycling. The hysteresis originates from the intrinsic magnetic anisotropy in the system. The observation of this phenomenon leads to open questions in the general understanding of magnetic heterostructures. Moreover, this shows that in general heterogeneous nanostructured materials may exhibit unexpected phenomena absent in the bulk.

description: In 2005, Portugal introduced a business registration reform - the On the Spot Firm program - with the goal of promoting the establishment of new start-ups and, ultimately, stimulating investment and economic growth. However, the question remains as to whether this policy has successfully achieved these goals. In this paper, we exploit the fact that the registration reform was introduced in different counties at different time periods (between 2005 and 2008) and use unique detailed micro-level data to examine the effects of deregulation in start-ups entry, performance and survival. The results show that the program increases the number of start-ups by approximately 17.2 percent and creates seven new jobs per month, county and 100,000 inhabitants in eligible industries. However, this increase is driven by young, female, less educated and less experienced individuals who decided to open non technology-based businesses, particularly agricultural, retail trade and construction firms. Additionally, we also find that start-ups established after the program are smaller and less likely to survive in the first two years than firms founded in counties without this program. Overall, we find some evidence that former entry regulation inhibits low ability individuals from establishing firms, acting as a screening mechanism to low quality ideas, as suggested by public interest theory.

description: Прямокишечно-влагалищные свищи являются одной из трудных и до конца не решенных проблем колопроктологии, тазовой хирургии, гинекологии и урологии. Предложены разнообразные методы хирургического лечения ректовагинальных свищей. Несмотря на это, удельный вес рецидивов заболевания и послеоперационных осложнений остается высоким. Основной причиной этого является отсутствие индивидуального подхода к определению способа хирургического лечения ректовагиналь-ных свищей, что побуждает к поиску более новых хирургических технологий и разработке алгоритмов лечения. Из всех генитальных свищей наиболее часто (49,3% наблюдений) встречаются кишечно-генитальные.

description: The effects of hole injection in amorphous-IGZO is analyzed by means of first-principles calculations. The injection of holes in the valence band tail states leads to their capture as a polaron, with high self-trapping energies (from 0.44 to 1.15 eV). Once formed, they mediate the formation of peroxides and remain localized close to the hole injection source due to the presence of a large diffusion energy barrier (of at least 0.6eV). Their diffusion mechanism can be mediated by the presence of hydrogen. The capture of these holes is correlated with the low off-current observed for a-IGZO transistors, as well as, with the difficulty to obtain a p-type conductivity. The results further support the formation of peroxides as being the root cause of Negative bias illumination stress (NBIS). The strong self-trapping substantially reduces the injection of holes from the contact and limits the creation of peroxides from a direct hole injection. In presence of light, the concentration of holes substantially rises and mediates the creation of peroxides, responsible for NBIS.

description: Using the renormalized quasiparticle random phase approximation (RQRPA), we calculate the light neutrino mass mediated mode of neutrinoless double beta decay of Ge76, Mo100, Te128 and Te130. Our results indicate that the simple quasiboson approximation is not good enough to study the neutrinoless double beta decay, because its solutions collapse for physical values of g_pp. We find that extension of the Hilbert space and inclusion of the Pauli Principle in the QRPA with proton-neutron pairing, allows us to extend our calculations beyond the point of collapse, for physical values of the nuclear force strength. As a consequence one might be able to extract more accurate values on the effective neutrino mass by using the best available experimental limits on the half-life of neutrinoless double beta decay.

description: Theoretically calculated power spectra are compares with observed solar p-mode velocity power spectra over a range of mode degree and frequency. The depth for the sources responsible for exciting p-modes of frequency 2.0 mHz is determined from the asymmetry of their power spectra and found to be about 800 km below the photosphere for quadrupole sources and 150 km if sources are dipole. The source depth for high frequency oscillations of frequency greater than about 6 mHz is 180 (50) km for quadrupole (dipole) sources.

description: A majority of American teenagers work during high school, constituting a large time commitment that pulls teens’ attention away from family, friends, school, and community ties. The issue of whether the possible costs to the other parts of teens’ lives outweigh the benefits from working has attracted extensive research, but no consensus exists about the relationship of part-time work on academic outcomes. This study uses the Bureau of Labor Statistics’ National Longitudinal Survey of Youth (NLSY) from 1997 to examine the impact of working part-time on high school dropout rates and grade point average at age 17. After age 16, federal legislation no longer limits the hours or duties of child labor. However, child labor legislation across different states limits the number of hours that teenagers are allowed to work. By exploiting this variation, the study examines whether a teen’s hours of work during the age 16 school year has a statistically significant relationship to his or her performance at school. Average hours of work did not have a statistically significant relationship with academic outcomes when using instrumental variables compared to statistically significant results when using ordinary least squares (OLS). Due to the weakness of the first-stage relationships and large standard errors, I am not able to draw conclusions about the work-dropout relationship or the work-GPA relationship.

description: There is a formative connection between structural choice and architectural design. Where the term “low hanging fruit” has often been used with reference to critical first choices towards climate responsive sustainable design, a similar approach can be applied to design-thinking when it comes to structural choices. The consideration of the material nature of the primary structure at the conceptual stage of design can allow for improved focus during the design process. This is particularly critical when working with exposed structural systems as the materiality also directly impacts the aesthetics. Exposing a structure requires that the architect be significantly more technically knowledgeable in order to remain in control of the design outcomes. This paper will elaborate an approach to instilling this type of design-thinking as it pertains to structural systems. It will look at the advantages of adopting a directed or limited structural palette in earlier design based exercises as a means of acquiring a higher level of expertise that can lead into more adeptness when dealing with the complexity associated with multiple materials. It will demonstrate that limitations can actually be liberating. Sample case studies will be used as a means to support and explore this pedagogical approach to design.
Quasistatic elastoplasticity via Peridynamics: existence and localization

description: Peridynamics is a nonlocal continuum-mechanical theory based on minimal regularity on the deformations. Its key trait is that of replacing local constitutive relations featuring spacial differential operators with integrals over differences of displacement fields over a suitable positive interaction range. The advantage of such perspective is that of directly including nonregular situations, in which discontinuities in the displacement field may occur. In the linearized elastic setting, the mechanical foundation of the theory and its mathematical amenability have been thoroughly analyzed in the last years. We present here the extension of Peridynamics to linearized elastoplasticity. This calls for considering the time evolution of elastic and plastic variables, as the effect of a combination of elastic energy storage and plastic energy dissipation mechanisms. The quasistatic evolution problem is variationally reformulated and solved by time discretization. In addition, by a rigorous evolutive $Γ$-convergence argument we prove that the nonlocal peridynamic model converges to classic local elastoplasticity as the interaction range goes to zero.

description: We construct BRST invariant solitonic states in the OSp invariant string field theory for closed bosonic strings. Our construction is a generalization of the one given in the noncritical case. These states are made by using the boundary states for D-branes, and can be regarded as states in which D-branes or ghost D-branes are excited. We calculate the vacuum amplitude in the presence of solitons perturbatively and show that the cylinder amplitude for the D-brane is reproduced. The results imply that these are states with even number of D-branes or ghost D-branes.
