description: The paper analyzes the use of late 19th – early 20th century photographs by Antoin Sevruguin in the paperback edition by Helsinki-based author Ivar Lassy Behind Lattice and Veil (Helsinki, Otago, 1917). Photographer Antoin Sevruguin, originally Russian, lived and worked in Tehran from late 1860s up until his death in 1933. A generalized picture of a Persian woman is among the most common motifs of photographs that had been bought from Sevruguin studio by travelers and researchers alike, and eventually landed in the West. This paper looks closer at the re-contextualization of Sevruguin’s images in Lassy’s book as an example of adaptation of photographs as means of cultural representation by both popular and scientific discourse of the Orient.

description: We have developed a modified Nagel-Schreckenberg cellular automata model for describing a conflicting vehicular traffic flow at the intersection of two streets. No traffic lights control the traffic flow. The approaching cars to the intersection yield to each other to avoid collision. Closed boundary condition is applied to the streets. Extensive Monte Carlo simulations is taken into account to find the model characteristics. In particular, we obtain the fundamental diagrams and show that the effect of interaction of two streets can be regarded as a dynamic impurity located at the intersection point. Our results suggest that yielding mechanism gives rise to a high total flow throughout the intersection especially in the low density regime. In some ranges of densities, yielding mechanism even improves and regulates the flow in comparison to the absence of perpendicular flow.

description: Charge transfer and electron-phonon coupling (EPC) are proposed to be two important constituents associated with enhanced superconductivity in the single unit cell FeSe films on oxide surfaces. Using high-resolution electron energy loss spectroscopy combined with first-principles calculations, we have explored the lattice dynamics of ultrathin FeSe films grown on SrTiO3. We show that, despite the significant effect from the substrate on the electronic structure and superconductivity of the system, the FeSe phonons in the films are unaffected. The energy dispersion and linewidth associated with the Fe- and Se-derived vibrational modes are thickness- and temperature-independent. Theoretical calculations indicate the crucial role of antiferromagnetic correlation in FeSe to reproduce the experimental phonon dispersion. Importantly, the only detectable change due to the growth of FeSe films is the broadening of the Fuchs-Kliewer (F-K) phonons associated with the lattice vibrations of SrTiO$_3$(001) substrate. If EPC plays any role in the enhancement of film superconductivity, it must be the interfacial coupling between the electrons in FeSe film and the F-K phonons from substrate rather than the phonons of FeSe.

We demonstrate that the complexification procedure followed by a restriction to a specified real Hamiltonian form commutes with the external automorphisms of $\mathfrak{g}$. This is illustrated on the examples ${\bf D}_{r+1}^{(1)} \to {\bf B}_r^{(1)}$ and ${\bf D}_4^{(1)} \to {\bf G}_2^{(1)}$ using external automorphisms of the corresponding extended Dynkin diagrams.

description: Linear response analysis in the nonequilibrium steady state (Gaussian regime) provides two independent fluctuation-response relations. One, in the form of the symmetric matrix, manifests the departure from the equilibrium formula through the quantity so-called {\it irreversible circulation}. The other, in the anti-symmetric form, connects the asymmetries in the fluctuation and the response function. These formulas represent characteristic features of fluctuations far from equilibrium, which have no counterparts in thermal equilibrium.

The self-fulfilling effects of the business week graduate business school ranking
Creators: name: Yew Choe Wong
Publisher: name: Carnegie Mellon University
Year: 2006
Subjects: Economics

description: Previous research in quantifying the effects of the widely popular Business Week graduate business school ranking on its users and stakeholders were not comprehensive in encompassing the programs that are not ranked in the top tier and in examining the different aspects of its influences. This paper adopts a more thorough approach in studying the effects of the changes in rankings on 22 variables related to admission outcomes, student quality, school demography, pricing policies and placement success. While it is not surprising that the Business Week ranking affects people’s perception and behavior, the analyses here uncover effects of substantial magnitude on some variables, especially when the ranking of an institution moves across the three different tiers. Falling ranking may put a school under serious financial distress due to shrinking enrollment and reduction in tuition income. While the school only increases the indirect price discount such as grant and scholarship aid when its ranking drops within the 1st tier, it has to be much more aggressive in attracting additional students from its declining applicant pool through direct tuition cut when it plummets to the 2nd or 3rd tiers. Besides, the resulting entering class is of slightly lower quality, as measured by its mean values of GMAT scores, undergraduate GPA, work experience and pre-MBA salary. Surprisingly, the career prospect of recent graduates is only adversely affected when a program plunges to a lower tier in the rankings; it appears that falling in the rankings within the 1st tier is actually favorable to their career placement. In addition, the cost of a program not being ranked in the media rankings are heavily borne by its recent graduates as their career prospect will be greatly impaired.

description: Electron microscopy is a powerful tool for studying the properties of materials down to their atomic structure. In many cases, the quantitative interpretation of images requires simulations based on atomistic structure models. These typically use the independent atom approximation that neglects bonding effects, which may, however, be measurable and of physical interest. Since all electrons and the nuclear cores contribute to the scattering potential, simulations that go beyond this approximation have relied on computationally highly demanding all-electron calculations. Here, we describe a new method to generate ab initio electrostatic potentials when describing the core electrons by projector functions. Combined with an interface to quantitative image simulations, this implementation enables an easy and fast means to model electron microscopy images. We compare simulated transmission electron microscopy images and diffraction patterns to experimental data, showing an accuracy equivalent to earlier all-electron calculations at a much lower computational cost.

description: We present $UBVI_c$ CCD photometry of the young open cluster Stock 8 with the aim to study the basic properties and star formation scenario in this region. The radius of the cluster is found to be $\sim 6^{\prime}$ ($\sim 3.6$ pc) and the reddening within the cluster region varies from $E(B-V)=0.40$ to 0.60 mag. The cluster is located at a distance of $2.05 \pm 0.10$ kpc. Using H$α$ slitless spectroscopy and 2MASS NIR data we identified H$α$ emission and NIR excess young stellar objects (YSOs), respectively. The colour-magnitude diagrams of these YSOs reveal that majority of these objects have ages between 1 to 5 Myr indicating a non-coeval star formation in the cluster. Massive stars in the cluster region reveal an average age of $\le$ 2 Myr. In the cluster region ($r \le 6^\prime$) the slope of the mass function (MF), $Γ$, in the mass range $\sim 1.0 \le M/M_\odot < 13.4$ can be represented by a power law having a slope of $-1.38\pm0.12$, which agrees well with Salpeter value (-1.35). In the mass range $0.3 \le M/M_\odot < 1.0$, the MF is also found to follow a power law with a shallower slope of $Γ= -0.58\pm 0.23$ indicating a break in the slope of the IMF at $\sim 1 M_\odot$. The slope of the $K$-band luminosity function for the cluster ($r \le 6^\prime$) is found to be $0.31\pm0.02$, which is smaller than the average value ($\sim$ 0.4) obtained for embedded star clusters. A significant number of YSOs are distributed along a Nebulous Stream towards the east side of the cluster. A small cluster is embedded in the Nebulous Stream. The YSOs lying in the Nebulous Stream and in the embedded cluster are found to be younger than the stars in the cluster Stock 8. It appears that star formation activity in the Nebulous Stream and embedded cluster may be independent from that of Stock 8.

description: Contributions of the pre-ionized H$_2$ (PI-H$_2$) and ionized H$_2^+$ subsystems of the two-electron H$_2$ system to its high-order harmonic generation in 8-cycle $\sin^{2}$-like ultrafast intense laser pulses are calculated and analyzed based on the solution of the time-dependent Schrödinger equation (TDSE) for the one-dimensional two-electronic H$_2$ system with fixed nuclei. The laser pulses have $λ =\ 390\ \&\ 532$ nm wavelengths and $I=1\times 10^{14}$, 5$\times 10^{14}$, 1$\times 10^{15}$ \&\ 5$\times 10^{15}$ Wcm$^{-2}$ intensities. It is found that at the two lower intensities, the PI-H$_2$ subsystem dominantly produces the HHG spectra. While, at the two higher intensities, both PI-H$_2$ and ionized H$_2^+$ subsystems contribute comparably to the HHG spectra. In the H$_2^+$ subsystem, the symmetry of the populations of H$_2^+$(I) and H$_2^+$(II) regions (left and right regions of H$_2^+$ subsystem) is broken by increasing the laser intensity. Complex patterns and even harmonics also appear at these two higher intensities. For instance, at $1\times 10^{15}$ Wcm$^{-2}$ intensity and $λ$ = 532 nm, the even harmonics are appeared near cut-off region. Interestingly, at $5\times 10^{15}$ Wcm$^{-2}$ intensity and $λ$ = 390 nm, the even harmonics replaced by the odd harmonics with red shift. At $λ$ = 390 \&\ 532 nm and $I=1\times 10^{15}$ intensity, the two-electron cutoffs corresponding to nonsequential double-recombination (NSDR) with maximum return kinetic energy of 4.70$U_p$ are detected. The HHG spectra of the whole H$_2$ system obtained with and without nuclear dynamics treated classically are approximately similar. However, at $1\times 10^{15}$ Wcm$^{-2}$ intensity and $λ$ = 532 nm, if we take into account nuclear dynamics, the even harmonics which are appeared near cutoff region, replaced by the odd harmonics with blue shift.

description: Burton-Cabrera-Frank (BCF) theory has proven to be a versatile framework to relate surface morphology and dynamics during crystal growth to the underlying mechanisms of adatom diffusion and attachment at steps. For an important class of crystal surfaces, including the basal planes of hexagonal close-packed and related systems, the steps in a sequence on a vicinal surface can exhibit properties that alternate from step to step. Here we develop BCF theory for such surfaces, relating observables such as alternating terrace widths as a function of growth conditions to the kinetic coefficients for adatom attachment at steps. We include the effects of step transparency and step-step repulsion. A general solution is obtained for the dynamics of the terrace widths, assuming quasi-steady-state adatom distributions on the terraces. An explicit simplified analytical solution is obtained under widely applicable approximations. From this we obtain expressions for the full-steady-state terrace fraction as a function of growth rate. Fits of the theoretical predictions to recent experimental determinations of the steady-state and dynamics of terrace fractions on GaN (0001) surfaces during organo-metallic vapor phase epitaxy give values of the kinetic coefficients for this system. In Appendices, we also connect a model for diffusion between kinks on steps to the model for diffusion between steps on terraces, which quantitatively relates step transparency to the kinetics of atom attachment at kinks, and consider limiting cases of diffusion-limited, attachment-limited, and mixed kinetics.

description: Implicit learning, behavioral change accompanied by an inability to consciously describe the means by which it has occurred, has been demonstrated in a number of domains. One question concerns the role of working memory in the learning process – if participants do not have conscious access to the learned information, what is the role of conscious attention and working memory in their learning? This paper further explores the question by studying the role of working memory on transferability of implicitly learned knowledge in the Balls and Boxes problem. Participants were given a puzzle to solve and then either the same puzzle or a horizontally inverted isomorph under single-task or working-memory interference conditions. As hypothesized, participants have little difficulty transferring their learned knowledge to the new problem unless their working memory is loaded.

description: Obtaining the physical mechanism of photoelectric transfer in quantum-dot (QD) photocells may be one strategy to boost the photovoltaic conversion efficiency. In this work, we attempted to formulate a novel theoretical approach to evaluate photocells' performance via evaluating their thermodynamic evolution during the photoelectric conversion process in a double quantum dot (DQD) photocell model. Results demonstrate that the thermodynamic-related quantities can reflect the law of photovoltaic dynamics, i.e., the photoelectric transfer properties can be evaluated by the heat currents indirectly. The merit of this work not only expands our understanding of the physical law of heat currents in the photoelectric transport process, but it may also propose a new method for optimizing photoelectric conversion efficiency in a DQD photocell.

Our estimates show that a substantial fraction of $B \rightarrow X_s ψ$ results in higher resonances of K-meson and besides $B \rightarrow K(K^*) ψ$, a considerable fraction of $B \rightarrow X_s (c\bar c)$ goes to $B \rightarrow (K,K^*)+( ψ^{\prime},χ_{1c})$.

description: Diffusion-based classifiers such as those relying on the Personalized PageRank and the Heat kernel, enjoy remarkable classification accuracy at modest computational requirements. Their performance however is affected by the extent to which the chosen diffusion captures a typically unknown label propagation mechanism, that can be specific to the underlying graph, and potentially different for each class. The present work introduces a disciplined, data-efficient approach to learning class-specific diffusion functions adapted to the underlying network topology. The novel learning approach leverages the notion of "landing probabilities" of class-specific random walks, which can be computed efficiently, thereby ensuring scalability to large graphs. This is supported by rigorous analysis of the properties of the model as well as the proposed algorithms. Furthermore, a robust version of the classifier facilitates learning even in noisy environments. Classification tests on real networks demonstrate that adapting the diffusion function to the given graph and observed labels, significantly improves the performance over fixed diffusions; reaching -- and many times surpassing -- the classification accuracy of computationally heavier state-of-the-art competing methods, that rely on node embeddings and deep neural networks.

description: Galaxy spectra are essential to probe the spatial distribution of galaxies in our Universe. To better interpret current and future spectroscopic galaxy redshift surveys, it is important to be able to simulate these data sets. We describe Uspec, a forward modeling tool to generate galaxy spectra taking into account some intrinsic galaxy properties as well as instrumental responses of a given telescope. The model for the intrinsic properties of the galaxy population, i.e., the luminosity functions, and size and spectral coefficients distribu- tions, was developed in an earlier work for broad-band imaging surveys [1], and we now aim to test the model further using spectroscopic data. We apply Uspec to the SDSS/CMASS sample of Luminous Red Galaxies (LRGs). We construct selection cuts that match those used to build this LRG sample, which we then apply to data and simulations in the same way. The resulting real and simulated average spectra show a good statistical agreement overall, with residual differences likely coming from a bluer galaxy population of the simulated sam- ple. We also do not explore the impact of non-solar element ratios in our simulations. For a quantitative comparison, we perform Principal Component Analysis (PCA) of the sets of spectra. By comparing the PCs constructed from simulations and data, we find good agree- ment for all components. The distributions of the eigencoefficients also show an appreciable overlap. We are therefore able to properly simulate the LRG sample taking into account the SDSS/BOSS instrumental responses. The differences between the two samples can be ascribed to the intrinsic properties of the simulated galaxy population, which can be reduced by further improvements of our modelling method in the future. We discuss how these results can be useful for the forward modeling of upcoming large spectroscopic surveys.

description: We study the statistical properties of geodesics, i.e. paths of minimal length, in large random planar quadrangulations. We extend Schaeffer's well-labeled tree bijection to the case of quadrangulations with a marked geodesic, leading to the notion of "spine trees", amenable to a direct enumeration. We obtain the generating functions for quadrangulations with a marked geodesic of fixed length, as well as with a set of "confluent geodesics", i.e. a collection of non-intersecting minimal paths connecting two given points. In the limit of quadrangulations with a large area n, we find in particular an average number 3*2^i of geodesics between two fixed points at distance i>>1 from each other. We show that, for generic endpoints, two confluent geodesics remain close to each other and have an extensive number of contacts. This property fails for a few "exceptional" endpoints which can be linked by truly distinct geodesics. Results are presented both in the case of finite length i and in the scaling limit i ~ n^(1/4). In particular, we give the scaling distribution of the exceptional points.

Ces documents comprennent tous les magistri qu’il avait pu rencontrer dans ses sources. Aux XIIème et XIIIème siècles, les universités n'existant pas encore, le titre de magister s'il évoque certainement une compétence n'est pas rattaché de façon systématique au passage par les écoles. De surcroît, les magistris sont le plus souvent désignés par leur seul prénom. La lecture de ces données est donc difficile et suppose un long travail pour tenter d'identifier un individu auquel on pourrait rattacher plusieurs mentions. John Baldwin avait donc renoncé à utiliser ces données pour donner un prolongement à sa magnifique étude sur les gradués d'université et leur emploi par les Capétiens et les Plantagenêts. Néanmoins, il a conservé ces données et elles sont potentiellement très utile dans le cadre de Studium, comme le sont toutes les mentions dans les volumes des Fasti Ecclesiae Gallicanae de chanoines portant ce titre de magister sans autres précisions. L'ampleur des dépouillements rend ces données très utiles et nous devons une grande reconnaissance à John Baldwin pour avoir pris la peine de faire photocopier ses fiches et de nous les avoir transmises amicalement.

description: We consider phylogeny estimation under a two-state model of sequence evolution by site substitution on a tree. In the asymptotic regime where the sequence lengths tend to infinity, we show that for any fixed $k$ no statistically consistent phylogeny estimation is possible from $k$-mer counts over the full leaf sequences alone. Formally, we establish that the joint distribution of $k$-mer counts over the entire leaf sequences on two distinct trees have total variation distance bounded away from $1$ as the sequence length tends to infinity. Our impossibility result implies that statistical consistency requires more sophisticated use of $k$-mer count information, such as block techniques developed in previous theoretical work.

The integral homology and cohomology rings of Gr are identified with dual Hopf algebras of symmetric functions, defined in terms of Schur's P and Q-functions. An explicit combinatorial description is obtained for the Schubert basis of the cohomology of Gr, and this is extended to a definition of the affine type C Stanley symmetric functions. A homology Pieri rule is also given for the product of a special Schubert class with an arbitrary one.

description: Identifying the behavior of photoexcited carriers is one method for empirically boosting their transfer efficiencies in doped double quantum dots (DQDs) photocells. The photoexcited carriers transfer qualities were assessed in this study by the output current, power, and output efficiency in the multi-photon absorption process for a doped DQDs photocell, and an optimization technique is theoretically obtained for this proposed photocell model. The results show that some structure parameters caused by doping, such as gaps, incoherent tunneling coupling, and symmetry of structure between two vertically aligned QDs, can remarkably control the photoexcited carriers transfer properties, and that slightly increasing the ambient temperature around room temperature is beneficial to the transfer performance in this doping DQDs photocell model. Thus, our scheme proves a way to optimized strategies for DQDs photocell.

description: Past research has shown that conflict occurs regularly in close relationships and has significant implications for relationship wellbeing. The purpose of this study was to investigate the role of perceived power in conflict resolution in romantic relationships. The study examined the power, relationship satisfaction, and conflict behaviors of 37 dating couples. Participants provided ratings of power and relationship satisfaction, and then participated in a 6-minute videotaped conflict discussion, which was systematically observed and coded for both positive and negative conflict behaviors. Results indicated that individuals with high perceived power demonstrated less positive and more negative affect during conflict. Furthermore, results demonstrated that perceived power equality versus inequality is associated with a number of behavioral tendencies during conflict, and gender is a significant moderator of these associations. Implications and directions for future research are discussed.

description: Double quantum dots (DQDs) have emerged as versatile and efficient absorbing light devices owing to their more multiple adjusting parameters than the single QD's. Using the system-reservoir theory, tunneling effect on the quantum photovoltaic properties is evaluated detailedly in a DQDs photocell with different energy mismatches under different temperatures. Repopulation of photo-generated carriers in two excited states is generated by electron tunneling effect between two coupled QD pairs, which brings out more efficient quantum photovoltaic yields evaluated by the short-circuit current, open-circuit voltage and output power through the current-voltage and power-voltage characteristics. Further discussion reveals that the quantum photovoltaic properties are enhanced by the ambient environment temperatures but weakened by the energy mismatches. However, the weakening effect caused by the energy mismatches can be greatly reduced by tunneling effect. Insights into tunneling effect between two adjacent QD not only facilitate a better understanding of the fundamentals in carriers transport, but also provide novel strategies for efficient artificial assembled QD arrays photocell inspired by this proposed DQDs photocell model.

description: In 2011 Runa Islam first exhibited a subtle and beautiful film that appropriated an enigmatic colonial glass plate negative, operated with it for both fracturing and multiplying its indexicality, and displaced the negative from – and even against – the history it would be expected to depict. By means of a formal and conceptual analysis of Sevruguin’s photographic work, one of the most important and idiosyncratic in the Middle East at the beginning of the 20th century, and analysis of both the enigmatic the negative Islam selected, and the film installation, the paper shows that Emergence must be regarded as a fine, conceptualist film that resists narrative, invites introspection, and stimulates a decolonial posture for opening a possible way of escape from the orientalist codifying gaze that persist in how Western Media records and communicates the ‘East’, and for confronting the cultural imaginary and colonialist gaze of a current process of crisis in 2011.

The Roads to Revolt: The Different Paths of the Vilna and Warsaw Ghettos

Subjects: History

description: The carnage that pervaded the Jewish communities of Eastern Europe had been envisioned by Adolf Hitler and the Schutzstaffel (S.S.) long before the German armored divisions crossed the flat plains of Poland in the fall of 1939. This war in Europe, a war that would become a global entanglement, was not limited to mere territorial pursuits in the quest for Lebensraum2, but was a war intended to decimate the “subhuman” Jewish entity that had, long in Nazi ideology, plagued Germany and the world. However, in the midst of their machinations, the Germans encountered something from the Jews that had been soundly unexpected from such an inferior race— the prospect of armed resistance within established Jewish ghettos. And yet, this is what the Germans encountered in the ghettos of Vilna (Lithuania) and Warsaw (Poland); Jews willing to fight and die, Jews who would not be deceived and led to slaughter, but Jewish men and women who were willing to believe in something again, if only for a short while. The story of Jewish resistance is neither simple nor symmetrical-- while the Jews of Warsaw rose in unity to defy their Nazi occupiers, the majority of the Jewish population of Vilna allowed themselves to be slowly siphoned off until almost nothing remained of the “Jerusalem of Lithuania.” Why did the Jews of Vilna not fit the mold of Warsaw and unite together and rise up in defiance of tyranny, especially considering that Vilna hosted an ideologically unified underground resistance movement, the Fareynikte Partizaner Organizatsye, or F.P.O.?3 This paper seeks to answer this question by comparing elements within the two ghettos that, the paper argues, may help explain their final outcomes. There is no definitive answer for why Vilna and Warsaw met such divergent fates; however, by focusing on several discernable factors within each ghetto and tracing the chronology of each, a much better understanding of why Vilna did not engage in the same unified resistance that embodied the epic tale of Jewish heroism during the Warsaw Uprising can be ascertained.
Dual peaks evoluting into single-peak for sub-wavelength 2-D atom localization in a V-type atomic system

description: The atom localization of a V-type atomic system is discussed by the detunings associated with the probe and the two orthogonal standing-wave fields, and by the spontaneously generated coherence (SGC). Within the half-wavelength domain in the 2-dimensional(2-D) plane, the atom localization depicted by the probe dual absorption peaks is achieved when the detunings are tuned. However, the dual peaks change into single-peak when the SGC arises. The single-peak 2-D localization demonstrated the advantage for atom localization achieved by the flexible manipulating parameters in our scheme.

description: We find numerical solutions of the coupled system of Einstein-Maxwell's equations with a linear approach, in which the magnetic field acts as a perturbation of a spherical neutron star. In our study, magnetic fields having both poloidal and toroidal components are considered, and higher order multipoles are also included. We evaluate the deformations induced by different field configurations, paying special attention to those for which the star has a prolate shape. We also explore the dependence of the stellar deformation on the particular choice of the equation of state and on the mass of the star. Our results show that, for neutron stars with mass M = 1.4 Msun and surface magnetic fields of the order of 10^15 G, a quadrupole ellipticity of the order of 10^(-6) - 10^(-5) should be expected. Low mass neutron stars are in principle subject to larger deformations (quadrupole ellipticities up to 10^(-3) in the most extreme case). The effect of quadrupolar magnetic fields is comparable to that of dipolar components. A magnetic field permeating the whole star is normally needed to obtain negative quadrupole ellipticities, while fields confined to the crust typically produce positive quadrupole ellipticities.

description: In this paper, we revisit an earlier conjecture by one of us that related conjugacy classes of $M_{12}$ to Jacobi forms of weight one and index zero. We construct Jacobi forms for all conjugacy classes of $M_{12}$ that are consistent with constraints from group theory as well as modularity. However, we obtain 1427 solutions that satisfy these constraints (to the order that we checked) and are unable to provide a unique Jacobi form. Nevertheless, as a consequence, we are able to provide a group theoretic proof of the evenness of the coefficients of all EOT Jacobi forms associated with conjugacy classes of $M_{12}:2 \subset M_{24}$. We show that there exists no solution where the Jacobi forms (for order 4/8 elements of $M_{12}$) transform with phases under the appropriate level. In the absence of a moonshine for $M_{12}$, we show that there exist moonshines for two distinct $L_2(11)$ sub-groups of the $M_{12}$. We construct Siegel modular forms for all $L_2(11)$ conjugacy classes and show that each of them arises as the denominator formula for a distinct Borcherds-Kac-Moody Lie superalgebra.

description: Aim: This study aimed to illuminate meanings of person-centredness as narrated by nursing home managers in nursing homes rated as highly person-centred. Design: A phenomenological hermeneutical approach was used. Methods: Twelve nursing home managers in 11 highly person-centred nursing homes in 7 municipalities in Sweden were included in this interview study. The findings were interpreted, reflected and discussed through the lens of Ricoeur. Results: Meanings of person-centredness could be understand as moving between doing and being through knowing, sensing, sharing and giving for person-centredness. These aspects contributed via knowledge, understanding, interaction and action that involved doing for and being with older persons through these caring dimensions. By moving between doing for, being with and being part of the overall nursing home narrative, knowing, sensing, sharing and giving could support the persons' identity in different ways. This may also contribute to sense-making, preserving dignity and promoting self-esteem when aiming to provide a good life for older persons in nursing homes, within an ever-present ethical frame. No Patient or Public Contribution: This study illuminated meanings of person-centredness as narrated by nursing home managers. No patient of public contribution was investigated.
The Rising Cost of Diabetes Care: Annual Variations in Expenditures, Decomposed by Price and Utilization

description: This project aims to analyze health care spending for patients with diabetes from 2006 to 2010. We begin by reviewing descriptive data on rising health care costs and the rising prevalence of diabetes nationwide, with a focus on the state of Florida. In our analysis, we use inpatient hospital data from Florida to construct an index that measures changes in health expenditures for diabetics. Based on these calculations, inpatient hospital spending on diabetes increased 23% for those insured by Medicaid, 25% for those insured by Medicare, and 10% for those with private insurance. We decompose these expenditure indexes into price and quantity components to understand whether increased spending is driven by higher prices or increased utilization. These indices are further broken down into age and sex cohorts. Overall we find significant variation in price and quantity changes, with the highest price increases for Medicaid recipients and greatest utilization increases for those with private insurance. Shifts in expenditures for females were generally driven by increased utilization, while shifts in expenditures for men were driven by price increases.
