Baxter Algebras and Umbral Calculus
Guo, Li
2004-01-01
We apply recent constructions of free Baxter algebras to the study of the umbral calculus. We give a characterization of the umbral calculus in terms of Baxter algebra. This characterization leads to a natural generalization of the umbral calculus that include the classical umbral calculus in a family of $\\lambda$-umbral calculi parameterized by $\\lambda$ in the base ring.
Baxter Aurora dialysis system.
Kelly, Thomas D
2004-01-01
With the recent focus on the benefits of more frequent dialysis, the Baxter Aurora dialysis system provides maximum flexibility for therapy prescription, including short daily treatments, long nocturnal treatments, hemodialysis, hemofiltration, and online hemodiafiltration, all in a compact, reliable, easy to use system. A self-prompting touch screen user interface mounted on a movable arm provides for comfortable operation, whether sitting and standing. An automatic treatment setup mode facilitates easy treatment setup. Complex menus are eliminated by the use of a hardware key that automatically selects only the prescribed options during power up, eliminating all menus associated with nonprescribed functions and modalities. This prevents the user from becoming confused or accidentally altering the dialysis treatment. Prior to dialysis the instrument goes through an automatic self-test that confirms the operation of internal systems. The screen will dim when there is no action that the patient needs to attend to on the instrument. After dialysis, press the disinfect button and the instrument disinfects itself and shuts off. For patient safety, the "disinfect" menus are not available during dialysis. The instrument can also be programmed to automatically start and rinse at a set time. For remote treatment monitoring, the instrument connects to the Internet. The Aurora records information about the machine's technical status, providing a record of instrument history for easy servicing. The Aurora is a flexible platform that provides the desired renal therapy with ease of use and proper support for the hemodialysis patient when combined with Baxter's 24-hour infrastructure and support.

The paper proposes an extension of the symmetric Baxter-King band pass filter to an asymmetric Baxter-King filter. The optimal correction scheme of the ideal filter weights is the same as in the symmetric version, i.e, cut the ideal filter at the appropriate length and add a constant to all filter weights to ensure zero weight on zero frequency. Since the symmetric Baxter-King filter is unable to extract the desired signal at the very ends of the series, the extension to an asymmetric filter...
Aztec Diamonds and Baxter Permutations
Canary, Hal
2003-01-01
We present a proof of a conjecture about the relationship between Baxter permutations and pairs of alternating sign matrices that are produced from domino tilings of Aztec diamonds. It is shown that if and only if a tiling corresponds to a pair of ASMs that are both permutation matrices, the larger permutation matrix corresponds to a Baxter permutation. There has been a thriving literature on both pattern-avoiding permutations of various kinds and tilings of regions using dominos or rhombuses...

Baxter Algebras, Stirling Numbers and Partitions
Guo, Li
2004-01-01
Recent developments of Baxter algebras have lead to applications to combinatorics, number theory and mathematical physics. We relate Baxter algebras to Stirling numbers of the first kind and the second kind, partitions and multinomial coefficients. This allows us to apply congruences from number theory to obtain congruences in Baxter algebras.
Localization of Rota-Baxter algebras
Chu, Chenghao; Guo, Li
2012-01-01
A commutative Rota-Baxter algebra can be regarded as a commutative algebra that carries an abstraction of the integral operator. With the motivation of generalizing the study of algebraic geometry to Rota-Baxter algebra, we extend the central concept of localization for commutative algebras to commutative Rota-Baxter algebras. The existence of such a localization is proved and, under mild conditions, its explicit constructions are obtained. The existence of tensor products of commutative Rota...
Baxter Q-operator and functional relations
A.A. Ovchinnikov
2015-03-01
Full Text Available We obtain the Baxter Q-operators in the Uq(slˆ2 invariant integrable models as a special limits of the quantum transfer matrices corresponding to different spins in the auxiliary space. We derive the Baxter equation from the well-known fusion relations for the transfer matrices. Our method is valid for an arbitrary integrable model corresponding to the quantum group Uq(slˆ2, for example for the XXZ-spin chain.
Yang-Baxter deformations of Minkowski spacetime
Matsumoto, Takuya; Reffert, Susanne; Sakamoto, Jun-ichi; Yoshida, Kentaroh
2015-01-01
We study Yang-Baxter deformations of 4D Minkowski spacetime. The Yang-Baxter sigma model description was originally developed for principal chiral models based on a modified classical Yang-Baxter equation. It has been extended to coset curved spaces and models based on the usual classical Yang-Baxter equation. On the other hand, for flat space, there is the obvious problem that the standard bilinear form degenerates if we employ the familiar coset Poincar\\'e group/Lorentz group. Instead we consider a slice of AdS$_5$ by embedding the 4D Poincar\\'e group into the 4D conformal group $SO(2,4)$. With this procedure we obtain metrics and $B$-fields as Yang-Baxter deformations which correspond to well-known configurations such as T-duals of Melvin backgrounds, Hashimoto-Sethi and Spradlin-Takayanagi-Volovich backgrounds, the T-dual of Grant space, pp-waves, and T-duals of dS$_4$ and AdS$_4$. Finally we consider a deformation with a classical $r$-matrix of Drinfeld-Jimbo type and explicitly derive the associated met...

Yang-Baxter deformations of Minkowski spacetime

We discuss Yang-Baxter sigma deformations of 4D Minkowski spacetime proposed recently. To avoid the degeneracy of the standard bilinear form associated with the familiar coset ISO(1,3)/SO(1,3), we consider a slice of AdS5 in Poincaré coordinates by embedding the 4D Poincaré group into the 4D conformal group SO(2,4). With this procedure we present the metrics and B-fields as Yang-Baxter deformations which correspond to well-known backgrounds such as T-duals of Melvin backgrounds, Hashimoto-Sethi and Spradlin-Takayanagi-Volovich backgrounds, pp-waves, and T-duals of dS4 and AdS4.

Inhomogeneous linear equation in Rota-Baxter algebra
Pietrzkowski, Gabriel
2014-01-01
We consider a complete filtered Rota-Baxter algebra of weight $\\lambda$ over a commutative ring. Finding the unique solution of a non-homogeneous linear algebraic equation in this algebra, we generalize Spitzer's identity in both commutative and non-commutative cases. As an application, considering the Rota-Baxter algebra of power series in one variable with q-integral as the Rota-Baxter operator, we show certain Eulerian identities.

Grassmann extensions of Yang–Baxter maps
In this paper we show that there are explicit Yang–Baxter (YB) maps with Darboux–Lax representation between Grassman extensions of algebraic varieties. Motivated by some recent results on noncommutative extensions of Darboux transformations, we first derive a Darboux matrix associated with the Grassmann-extended derivative nonlinear Schrödinger (DNLS) equation, and then we deduce novel endomorphisms of Grassmann varieties, which possess the YB property. In particular, we present ten-dimensional maps which can be restricted to eight-dimensional YB maps on invariant leaves, related to the Grassmann-extended NLS and DNLS equations. We consider their vector generalisations. (paper)
A Note on the Baxter-King Filter
Ulrich Woitek
1998-01-01
Recently, Baxter and King (1995) developed a bandpass filter which overcomes to some extent the well known drawbacks of the Hodrick-Prescott filter. In this paper, the circumstances under which the Baxter-King filter is preferable are identified, and a modification is presented which takes into account spurious side lobes generated by this method.
New Elliptic Solutions of the Yang-Baxter Equation
Chicherin, D.; Derkachov, S. E.; Spiridonov, V. P.
2016-02-01
We consider finite-dimensional reductions of an integral operator with the elliptic hypergeometric kernel describing the most general known solution of the Yang-Baxter equation with a rank 1 symmetry algebra. The reduced R-operators reproduce at their bottom the standard Baxter's R-matrix for the 8-vertex model and Sklyanin's L-operator. The general formula has a remarkably compact form and yields new elliptic solutions of the Yang-Baxter equation based on the finite-dimensional representations of the elliptic modular double. The same result is also derived using the fusion formalism.

The Yang-Baxter relation and gauge invariance
Kashaev, Rinat
2016-04-01
Starting from a quantum dilogarithm over a Pontryagin self-dual LCA group A, we construct an operator solution of the Yang-Baxter equation generalizing the solution of the Faddeev-Volkov model. Based on a specific choice of a subgroup B\\subset A and by using the Weil transformation, we also give a new non-operator interpretation of the Yang-Baxter relation. That allows us to construct a lattice QFT-model of IRF-type with gauge invariance under independent B-translations of local ‘spin’ variables. Dedicated to Professor Rodney Baxter on the occasion of his 75th birthday.
Yang–Baxter sigma models based on the CYBE
It is known that Yang–Baxter sigma models provide a systematic way to study integrable deformations of both principal chiral models and symmetric coset sigma models. In the original proposal and its subsequent development, the deformations have been characterized by classical r-matrices satisfying the modified classical Yang–Baxter equation (mCYBE). In this article, we propose the Yang–Baxter sigma models based on the classical Yang–Baxter equations (CYBE) rather than the mCYBE. This generalization enables us to utilize various kinds of solutions of the CYBE to classify integrable deformations. In particular, it is straightforward to realize partial deformations of the target space without loss of the integrability of the parent theory

Australia is a global leader in organic production and a minnow in global GMO production. Organic produce consistently sells at a premium, while genetically modified (GM) produce consistently sells at a discount. In the case of Marsh and Baxter, the facts were agreed but their interpretation was not and this proved fatal to the case. This was a dispute between two farmer neighbours at Kojonup, Western Australia. When the GMO moratorium was lifted in WA, Baxter promptly planted Monsanto GM can...
A Unified Algebraic Approach to Classical Yang-Baxter Equation

In this paper, the different operator forms of classical Yang-Baxter equation are given in the tensor expression through a unified algebraic method. It is closely related to left-symmetric algebras which play an important role in many fields in mathematics and mathematical physics. By studying the relations between left-symmetric algebras and classical Yang-Baxter equation, we can construct left-symmetric algebras from certain classical r-matrices and conversely, there is a natural classical ...
Rota-Baxter algebras and the Hopf algebra of renormalization
Recently, the theory of renormalization in perturbative quantum field theory underwent some exciting new developments. Kreimer discovered an organization of Feynman graphs into combinatorial Hopf algebras. The process of renormalization is captured by a factorization theorem for regularized Hopf algebra characters. Hereby the notion of Rota-Baxter algebras enters the scene. In this work we develop in detail several mathematical aspects of Rota-Baxter algebras as they appear also in other sectors closely related to perturbative renormalization, to wit, for instance multiple-zeta-values and matrix differential equations. The Rota-Baxter picture enables us to present the algebraic underpinning for the Connes-Kreimer Birkhoff decomposition in a concise way. This is achieved by establishing a general factorization theorem for filtered algebras. Which in turn follows from a new recursion formula based on the Baker-Campbell-Hausdorff formula. This allows us to generalize a classical result due to Spitzer to non-commutative Rota-Baxter algebras. The Baker-Campbell-Hausdorff based recursion turns out to be a generalization of Magnus' expansion in numerical analysis to generalized integration operators. We will exemplify these general results by establishing a simple representation of the combinatorics of renormalization in terms of triangular matrices. We thereby recover in the presence of a Rota-Baxter operator the matrix representation of the Birkhoff decomposition of Connes and Kreimer. (orig.)

Introduction to the Yang-Baxter Equation with Open Problems
Florin Nichita
2012-04-01
Full Text Available The Yang-Baxter equation first appeared in theoretical physics, in a paper by the Nobel laureate C. N. Yang, and in statistical mechanics, in R. J. Baxter’s work. Later, it turned out that this equation plays a crucial role in: quantum groups, knot theory, braided categories, analysis of integrable systems, quantum mechanics, non-commutative descent theory, quantum computing, non-commutative geometry, etc. Many scientists have found solutions for the Yang-Baxter equation, obtaining qualitative results (using the axioms of various algebraic structures or quantitative results (usually using computer calculations. However, the full classification of its solutions remains an open problem. In this paper, we present the (set-theoretical Yang-Baxter equation, we sketch the proof of a new theorem, we state some problems, and discuss about directions for future research.
Yang–Baxter invariance of the Nappi–Witten model
Hideki Kyono
2016-04-01
Full Text Available We study Yang–Baxter deformations of the Nappi–Witten model with a prescription invented by Delduc, Magro and Vicedo. The deformations are specified by skew-symmetric classical r-matrices satisfying (modified classical Yang–Baxter equations. We show that the sigma-model metric is invariant under arbitrary deformations (while the coefficient of B-field is changed by utilizing the most general classical r-matrix. Furthermore, the coefficient of B-field is determined to be the original value from the requirement that the one-loop β-function should vanish. After all, the Nappi–Witten model is the unique conformal theory within the class of the Yang–Baxter deformations preserving the conformal invariance.
Baxter Q-Operators and Representations of Yangians
Bazhanov, Vladimir V; Lukowski, Tomasz; Meneghelli, Carlo; Staudacher, Matthias
2010-01-01
We develop a new approach to Baxter Q-operators by relating them to the theory of Yangians, which are the simplest examples for quantum groups. Here we open up a new chapter in this theory and study certain degenerate solutions of the Yang-Baxter equation connected with harmonic oscillator algebras. These infinite-state solutions of the Yang-Baxter equation serve as elementary, "partonic" building blocks for other solutions via the standard fusion procedure. As a first example of the method we consider sl(n) compact spin chains and derive the full hierarchy of operatorial functional equations for all related commuting transfer matrices and Q-operators. This leads to a systematic and transparent solution of these chains, where the nested Bethe equations are derived in an entirely algebraic fashion, without any reference to the traditional Bethe ansatz techniques.

We consider Yang-Baxter equations arising from its associative analog and study corresponding exchange relations. They generate finite-dimensional quantum algebras which have form of coupled ${\\rm GL}(N)$ Sklyanin elliptic algebras. Then we proceed to a natural generalization of the Baxter-Belavin quantum $R$-matrix to the case ${\\rm Mat}(N,\\mathbb C)^{\\otimes 2}\\otimes {\\rm Mat}(M,\\mathbb C)^{\\otimes 2}$. It can be viewed as symmetric form of ${\\rm GL}(NM)$ $R$-matrix in the sense that the Planck constant and the spectral parameter enter (almost) symmetrically. Such type (symmetric) $R$-matrices are also shown to satisfy the Yang-Baxter like quadratic and cubic equations.

Yang–Baxter operators need quantum entanglement to distinguish knots
Any solution to the Yang–Baxter equation yields a family of representations of braid groups. Under certain conditions, identified by (Turaev 1988 Inventiones Math. 92 527–53), the appropriately normalized trace of these representations yields a link invariant. Any Yang–Baxter solution can be interpreted as a two-qudit quantum gate. Here we show that if this gate is non-entangling, then the resulting invariant of knots is trivial. We thus obtain a connection between topological entanglement and quantum entanglement. (paper)

In this paper, we introduce the concepts of Rota-Baxter operators and differential operators with weights on a multiplicative n-ary Hom-algebra. We then focus on Rota-Baxter multiplicative 3-ary Hom-Nambu-Lie algebras and show that they can be derived from Rota-Baxter Hom-Lie algebras, Hom-preLie algebras and Rota-Baxter commutative Hom-associative algebras. We also explore the connections between these Rota-Baxter multiplicative 3-ary Hom-Nambu-Lie algebras.
ℤ3 parafermionic chain emerging from Yang-Baxter equation

We construct the 1D parafermionic model based on the solution of Yang-Baxter equation and express the model by three types of fermions. It is shown that the parafermionic chain possesses both triple degenerate ground states and non-trivial topological winding number. Hence, the parafermionic model is a direct generalization of 1D Kitaev model. Both the and model can be obtained from Yang-Baxter equation. On the other hand, to show the algebra of parafermionic tripling intuitively, we define a new 3-body Hamiltonian based on Yang-Baxter equation. Different from the Majorana doubling, the holds triple degeneracy at each of energy levels. The triple degeneracy is protected by two symmetry operators of the system, ω-parity P and emergent parafermionic operator Γ, which are the generalizations of parity PM and emergent Majorana operator in Lee-Wilczek model, respectively. Both the parafermionic model and can be viewed as SU(3) models in color space. In comparison with the Majorana models for SU(2), it turns out that the SU(3) models are truly the generalization of Majorana models resultant from Yang-Baxter equation.
Quantum supergroups and solutions of the Yang-Baxter equation

Gauging quantum groups: Yang-Baxter joining Yang-Mills
Wu, Yong-Shi
2016-02-01
This review is an expansion of my talk at the conference on Sixty Years of Yang-Mills Theory. I review and explain the line of thoughts that lead to a recent joint work with Hu and Geer [Hu et al., arXiv:1502.03433] on the construction, exact solutions and ubiquitous properties of a class of quantum group gauge models on a honey-comb lattice. Conceptually the construction achieves a synthesis of the ideas of Yang-Baxter equations with those of Yang-Mills theory. Physically the models describe topological anyonic states in 2D systems.
Yang-Baxter R-operators and parameter permutations
We present an uniform construction of the solution to the Yang-Baxter equation with the symmetry algebra sl(2) and its deformations: the q-deformation and the elliptic deformation or Sklyanin algebra. The R-operator acting in the tensor product of two representations of the symmetry algebra with arbitrary spins l1 and l2 is built in terms of products of three basic operators S1, S2, S3 which are constructed explicitly. They have the simple meaning of representing elementary permutations of the symmetric group S4, the permutation group of the four parameters entering the RLL-relation
Parameter-dependent associative Yang-Baxter equations and Poisson brackets
Odesskii, Alexander; Rubtsov, Vladimir; Sokolov, Vladimir

We discuss associative analogues of classical Yang-Baxter equation (CYBE) meromorphically dependent on parameters. We discover that such equations enter in a description of a general class of parameter-dependent Poisson structures and double Lie and Poisson structures in sense of Van den Bergh. We propose a classification of all solutions for one-dimensional associative Yang-Baxter equations (AYBE).
Spatial symmetry, local integrability and tetrahedron equations in the Baxter-Bazhanov model
It is shown that the Baxter-Bazhanov model is invariant under the action of the cube symmetry group. The three-dimensional star-star relations, proposed by Baxter and Bazhanov as local integrability conditions, correspond to a particular transformation from this group. Invariant Boltzmann weights, parameterized in terms of the Zamolodchikov's angle variables, apparently satisfy the tetrahedron equations. 12 refs
Constructions of Rota-Baxter algebras from idempotent-like elements

Yang-Baxter algebras, integrable theories and Bethe Ansatz
This paper presents the Yang-Baxter algebras (YBA) in a general framework stressing their power to exactly solve the lattice models associated to them. The algebraic Behe Ansatz is developed as an eigenvector construction based on the YBA. The six-vertex model solution is given explicitly. The generalization of YB algebras to face language is considered. The algebraic BA for the SOS model of Andrews, Baxter and Forrester is described using these face YB algebras. It is explained how these lattice models yield both solvable massive QFT and conformal models in appropriated scaling (continuous) limits within the lattice light-cone approach. This approach permit to define and solve rigorously massive QFT as an appropriate continuum limit of gapless vertex models. The deep links between the YBA and Lie algebras are analyzed including the quantum groups that underlay the trigonometric/hyperbolic YBA. Braid and quantum groups are derived from trigonometric/hyperbolic YBA in the limit of infinite spectral parameter. To conclude, some recent developments in the domain of integrable theories are summarized

We consider a class of asymptotic representations of the Borel subalgebra of the quantum affine superalgebra U{sub q}(gl{sup ^}(M|N)). This is characterized by Drinfeld rational fractions. In particular, we consider contractions of U{sub q}(gl(M|N)) in the FRT formulation and obtain explicit solutions of the graded Yang–Baxter equation in terms of q-oscillator superalgebras. These solutions correspond to L-operators for Baxter Q-operators. We also discuss an extension of these representations to the ones for contracted algebras of U{sub q}(gl{sup ^}(M|N)) by considering the action of renormalized generators of the other side of the Borel subalgebra. We define model independent universal Q-operators as the supertrace of the universal R-matrix and write universal T-operators in terms of these Q-operators based on shift operators on the supercharacters.

We discuss how the shift operator and the Hamiltonian enter the hierarchy of Baxter Q-operators in the example of gl(n) homogeneous spin-chains. Building on the construction that was recently carried out by the authors and their collaborators, we find that a reduced set of Q-operators can be used to obtain local charges. The mechanism relies on projection properties of the corresponding R-operators on a highest/lowest weight state of the quantum space. It is intimately related to the ordering of the oscillators in the auxiliary space. Furthermore, we introduce a diagrammatic language that makes these properties manifest and the results transparent. Our approach circumvents the paradigm of constructing the transfer matrix with equal representations in quantum and auxiliary space and underlines the strength of the Q-operator construction.

The Yang-Baxter equation is an important tool in theoretical physics, with many applications in different domains that span from condensed matter to string theory. Recently, the interest on the equation has increased due to its connection to quantum information processing. It has been shown that the Yang-Baxter equation is closely related to quantum entanglement and quantum computation. Therefore, owing to the broad relevance of this equation, besides theoretical studies, it also became significant to pursue its experimental implementation. Here, we show an experimental realization of the Yang-Baxter equation and verify its validity through a Nuclear Magnetic Resonance (NMR) interferometric setup. Our experiment was performed on a liquid state Iodotrifluoroethylene sample which contains molecules with three qubits. We use Controlled-transfer gates that allow us to build a pseudo-pure state from which we are able to apply a quantum information protocol that implements the Yang-Baxter equation. PMID:26861686

This paper focuses on the study of topological features in teleportation-based quantum computation and aims at presenting a detailed review on teleportation-based quantum computation (Gottesman and Chuang in Nature 402: 390, 1999). In the extended Temperley-Lieb diagrammatical approach, we clearly show that such topological features bring about the fault-tolerant construction of both universal quantum gates and four-partite entangled states more intuitive and simpler. Furthermore, we describe the Yang-Baxter gate by its extended Temperley-Lieb configuration and then study teleportation-based quantum circuit models using the Yang-Baxter gate. Moreover, we discuss the relationship between the extended Temperley-Lieb diagrammatical approach and the Yang-Baxter gate approach. With these research results, we propose a worthwhile subject, the extended Temperley-Lieb diagrammatical approach, for physicists in quantum information and quantum computation.
A q-difference Baxter operator for the Ablowitz–Ladik chain
We construct the Baxter operator and the corresponding Baxter equation for a quantum version of the Ablowitz–Ladik model. The result is achieved in two different ways: by using the well-known Bethe ansatz technique and by looking at the quantum analogue of the classical Bäcklund transformations. General results about integrable models governed by the same r-matrix algebra will be given. Baxter’s equation comes out to be a q-difference equation involving both the trace and the quantum determinant of the monodromy matrix. The spectrality property of the classical Bäcklund transformations gives a trace formula representing the classical analogue of Baxter’s equation. A q-integral representation of the Baxter operator is discussed. (paper)
Using computer algebra for Yang-Baxterization applied to quantum computing
Vélez, Mario; Ospina, Juan
2006-05-01
Using Computer Algebra Software (Mathematica and Maple), the recently introduced topic of Yang- Baxterization applied to quantum computing, is explored from the mathematical and computational views. Some algorithms of computer algebra were elaborated with the aim to make the calculations to obtain some of results that were originally presented in the paper by Shang-Kauffman-Ge. Also certain new results about computational Yang-baxterization are presented. We obtain some Hamiltonians for hypothetical physical systems which can be realized within the domain of spin chains and certain diffusion process. We conclude that it is possible to have real physical systems on which implement, via Yang-baxterization, the standard quantum gates with topological protection. Finally some lines for future research are deligned.

The q-oscillator representation for the Borel subalgebra of the affine symmetry U'{sub q}(sl{sub N}-hat) is presented. By means of this q-oscillator representation, we give the free field realizations of Baxter's Q-operator Q{sub j}({lambda}), Q-bar{sub j}({lambda}), (j=1,2,...,N) for the W-algebra W{sub N}. We give functional relations of the T-Q operators, including the higher-rank generalization of Baxter's T-Q relation.

We show how the Hintermann-Merlini-Baxter-Wu model (which is a generalization of the well-known Baxter-Wu model to a general Eulerian triangulation) can be mapped onto a particular infinite-coupling-limit of the Ashkin-Teller model. We work out some mappings among these models, also including the standard and mixed Ashkin-Teller models. Finally, we compute the phase diagram of the infinite-coupling-limit Ashkin-Teller model on the square, triangular, hexagonal, and kagome lattices.
Non-associative algebras, Yang-Baxter equations, and quantum computers
Non-associative algebras is a research direction gaining much attention these days. New developments show that associative algebras and some not-associative structures can be unified at the level of Yang-Baxter structures. In this paper, we present a unification for associative algebras, Jordan algebras and Lie algebras. The (quantum) Yang-Baxter equation and related structures are interesting topics, because they have applications in many areas of physics, mathematics, and computer science. Several new interpretations and results are presented in this paper

In this letter, the connection is found between the "star-square" relation in the Baxter-Bazhanov model and the "star-triangle" relation in the chiral Potts model, which means that the tetrahedron equation of the Baxter-Bazhanov model is a consequence of the latter. The four additional constraints in the tetrahedron equation given by Kashaev et al. hold naturally in respect to the spherical trigonometry parametrizations.

Solutions of the quantum Yang-Baxter equation with extra nonadditive parameters
We present a systematic technique to construct solutions to the Yang-Baxter equation which depend not only on a spectral parameter but in addition on further continuous parameters. These extra parameters enter the Yang-Baxter equation in a similar way to the spectral parameter but in a non-additive form. We exploit the fact that quantum non-compact algebras such as Uq(su(1,1)) and type-I quantum superalgebras such as Uq(gl(1 mod 1)) and Uq(gl(2 mod 1)) are known to admit non-trivial one-parameter families of infinite-dimensional and finite-dimensional irreps, respectively, even for generic q. We develop a technique for constructing the corresponding spectral-dependent R-matrices. As examples, we work out the the R-matrices for the three quantum algebras mentioned above in certain representations. (author)
From representations of the braid group to solutions of the Yang-Baxter equation
A systematic method is developed for constructing solutions of the Yang-Baxter equation from given braid group representations, arising from such finite dimensional irreps of quantum groups that any irrep can be affinized and the tensor product of the irrep with itself is multiplicity-free. The main tool used in the construction is a tensor product graph, whose circuits give rise to consistency conditions. A maximal tree of this graph leads to an explicit formula for the quantum R-matrix when the consistency conditions are satisfied. As examples, new solutions of the Xang-Baxter equations are found, corresponding to braid group generators associated with the symmetric and antisymmetric tensor irreps of Uq[gl(m)], a spinor irrep of Uq[so(2n)], and the minimal irreps of Uq[E6] and Uq[E7].

ABSTRACT: We present a systematic technique to construct solutions to the Yang-Baxter equation which depend not only on a spectral parameter but in addition on further continuous parameters. These extra parameters enter the Yang-Baxter equation in a similar way to the spectral parameter but in a non-additive form. We exploit the fact that quantum non-compact algebras such as U_q(su(1,1)) and type-I quantum superalgebras such as U_q(gl(1|1)) and U_q(gl(2|1)) are known to admit non-trivial one-parameter families of infinite-dimensional and finite dimensional irreps, respectively, even for generic q. We develop a technique for constructing the corresponding spectral-dependent R-matrices. As examples we work out the the R-matrices for the three quantum algebras mentioned above in certain representations.
Yang–Baxter integrable models in experiments: from condensed matter to ultracold atoms
The Yang–Baxter equation has long been recognised as the masterkey to integrability, providing the basis for exactly solved models which capture the fundamental physics of a number of realistic classical and quantum systems. In this article we provide an introductory survey of the impact of Yang–Baxter integrable models on experiments in condensed matter physics and ultracold atoms. A number of prominent examples are covered, including the hard-hexagon model, the Heisenberg spin chain, the transverse quantum Ising chain, a spin ladder model, the Lieb–Liniger Bose gas, the Gaudin–Yang Fermi gas and the two-site Bose–Hubbard model. The review concludes by pointing to some other recent developments with promise for further progress. (review)
Baxter operators and Hamiltonians for “nearly all” integrable closed gl(n) spin chains
We continue our systematic construction of Baxter Q-operators for spin chains, which is based on certain degenerate solutions of the Yang–Baxter equation. Here we generalize our approach from the fundamental representation of gl(n) to generic finite-dimensional representations in quantum space. The results equally apply to non-compact representations of highest or lowest weight type. We furthermore fill an apparent gap in the literature, and provide the nearest-neighbor Hamiltonians of the spin chains in question for all cases where the gl(n) representations are described by rectangular Young diagrams, as well as for their infinite-dimensional generalizations. They take the form of digamma functions depending on operator-valued shifted weights

Deformations of $T^{1,1}$ as Yang-Baxter sigma models
Crichigno, P Marcos; Yoshida, Kentaroh
2014-01-01
We consider a family of deformations of T^{1,1} in the Yang-Baxter sigma model approach. We first discuss a supercoset description of T^{1,1}, which makes manifest the full symmetry of the space and leads to the standard Sasaki-Einstein metric. Next, we consider three-parameter deformations of T^{1,1} by using classical r-matrices satisfying the classical Yang-Baxter equation (CYBE). The resulting metric and NS-NS two-form agree exactly with the ones obtained via TsT transformations, and contain the Lunin-Maldacena background as a special case. It is worth noting that for AdS_5 x T^{1,1}, classical integrability for the full sector has been argued to be lost. Hence our result indicates that the Yang-Baxter sigma model approach is applicable even for non-integrable cosets. This observation suggests that the gravity/CYBE correspondence can be extended beyond integrable cases.

The tarsal tunnel is composed of the posterior border of the medial malleoulus, the posterior aspect of the talus and the medial aspect of the calcaneus. The medial calcaneal nerve emerges from the posterior aspect of the posterior tibial nerve in 75% of cases and from the lateral plantar nerve in the remaining 25%. Finally, the medial calcaneal nerve ends as a single terminal branch in 79% of cases and in numerous terminal branches in the remaining 21%. To describe the anatomical variants of the posterior tibial nerve and its terminal branches. To describe the steps for tarsal tunnel release. To describe Baxter nerve release. The anatomical variants of the posterior tibial nerve and its terminal branches within the tarsal tunnel were studied. Then the Lam technique was performed; it consists of: 1) opening of the laciniate ligament, 2) opening of the fascia over the abductor hallucis muscle, 3) exoneurolysis of the posterior tibial nerve and its terminal branches, identifying the emergence and pathway of the medial calcaneal branch, the lateral plantar nerve and its Baxter nerve branch and the medial plantar nerve. Baxter nerve was found in 100% of cases. In 100% of cases in our series the nerve going to the abductor digiti minimi muscle of the foot was found; 87.5% of cases had two terminal branches. The dissections proved that a crucial step was the release of the distal tarsal tunnel. PMID:24701749

In this paper we review the theory of the Yang–Baxter equation related to the 6-vertex model and its higher spin generalizations. We employ a 3D approach to the problem. Starting with the 3D R -matrix, we consider a two-layer projection of the corresponding 3D lattice model. As a result, we obtain a new expression for the higher spin R -matrix associated with the affine quantum algebra Uq(sl(2)ˆ) . In the simplest case of the spin s=1/2 this R -matrix naturally reduces to the R -matrix of the...
Yang-Baxter sigma models and Lax pairs arising from κ-Poincaré r-matrices
Borowiec, Andrzej; Kyono, Hideki; Lukierski, Jerzy; Sakamoto, Jun-ichi; Yoshida, Kentaroh
2016-04-01
We study Yang-Baxter sigma models with deformed 4D Minkowski spacetimes arising from classical r-matrices associated with κ-deformations of the Poincaré algebra. These classical κ-Poincaré r-matrices describe three kinds of deformations: 1) the standard deformation, 2) the tachyonic deformation, and 3) the light-cone deformation. For each deformation, the metric and two-form B-field are computed from the associated r-matrix. The first two deformations, related to the modified classical Yang-Baxter equation, lead to T-duals of dS4 and AdS4, respectively. The third deformation, associated with the homogeneous classical Yang-Baxter equation, leads to a time-dependent pp-wave background. Finally, we construct a Lax pair for the generalized κ-Poincaré r-matrix that unifies the three kinds of deformations mentioned above as special cases.
The Perk-Schultz model may be expressed in terms of the solution of the Yang-Baxter equation associated with the fundamental representation of the untwisted affine extension of the general linear quantum superalgebra Uq[gl(m vertical bar n)], with a multiparametric coproduct action as given by Reshetikhin. Here, we present analogous explicit expressions for solutions of the Yang-Baxter equation associated with the fundamental representations of the twisted and untwisted affine extensions of the orthosymplectic quantum superalgebras Uq[osp(m vertical bar n)]. In this manner, we obtain generalizations of the Perk-Schultz model. (letter to the editor)

An essential point is that the classical r-matrices are composed of Cartan generators only and then generate abelian twists. We present examples of the r-matrices that lead to real γ-deformations of the AdS5×S5 superstring. Finally we discuss a possible classification of integrable deformations and the corresponding gravity solution in terms of solutions of CYBE.

Yang–Baxter deformations, AdS/CFT, and twist-noncommutative gauge theory
Stijn J. van Tongeren
2016-03-01
Full Text Available We give an AdS/CFT interpretation to homogeneous Yang–Baxter deformations of the AdS5×S5 superstring as noncommutative deformations of the dual gauge theory, going well beyond the canonical noncommutative case. These homogeneous Yang–Baxter deformations can be of so-called abelian or jordanian type. While abelian deformations have a clear interpretation in string theory and many already had well understood gauge theory duals, jordanian deformations appear novel on both counts. We discuss the symmetry structure of the deformed string from the uniformizing perspective of Drinfeld twists and indicate that this structure can be realized on the gauge theory side by considering theories on various noncommutative spaces. We then conjecture that these are the gauge theory duals of our strings, modulo subtleties involving singularities. We support this conjecture by a brane construction for two jordanian examples, corresponding to noncommutative spaces with [x−,⋆xi]∼xi (i=1,2. We also discuss κ-Minkowski type deformations of AdS5×S5, one of which may be the gravity dual of gauge theory on spacelike κ-Minkowski space.
Canonical and noncanonical variables, Baxter's Q-operator and the XXX model
Baxter's Q-operator for the XXX model is analysed to study the different roles played by the canonical and noncanonical variables using the formalism of Sklyanin. In this approach to the study of Baecklund transformation (BT) and Baxter's Q-operator one requires two Lax operators obeying the same Poisson algebra (i.e. having the same classical r matrix). Usually the nonlinear variables in the Lax operator are canonically conjugate quantities. In this communication we have shown that even when the variables in one Lax operator are not canonical, it is still possible to construct the BT and Q-operator by a proper representation of the corresponding nonlinear variables. The price for this is that, the BT is not easily interpretable as a canonical transformation in the conventional sense of the term. However the Q-operator for the XXX chain turns out to be similar to that obtained by Derkachov [J Phys A 32 (1999) 316] using a similar representation but in a different manner. It is important to note that although, in contrast to the results obtained by Kuznetsov et al. [J Phys A 33 (2000) 171], the Q-operator depends on two adjacent sites (xi,xi-1), its relevant properties can be explicitly established
SO(d,1)-invariant Yang-Baxter operators and the dS/CFT correspondence
Hollands, Stefan
2016-01-01
We propose a model for the dS/CFT correspondence. The model is constructed in terms of a "Yang-Baxter operator" $R$ for unitary representations of the deSitter group $SO(d,1)$. This $R$-operator is shown to satisfy the Yang-Baxter equation, unitarity, as well as certain analyticity relations, including in particular a crossing symmetry. With the aid of this operator we construct: a) A chiral (light-ray) conformal quantum field theory whose internal degrees of freedom transform under the given unitary representation of $SO(d,1)$. By analogy with the $O(N)$ non-linear sigma model, this chiral CFT can be viewed as propagating in a deSitter spacetime. b) A (non-unitary) Euclidean conformal quantum field theory on ${\\mathbb R}^{d-1}$, where $SO(d,1)$ now acts by conformal transformations in (Euclidean) spacetime. These two theories can be viewed as dual to each other if we interpret ${\\mathbb R}^{d-1}$ as conformal infinity of deSitter spacetime. Our constructions use semi-local generator fields defined in terms o...
Supercoset construction of Yang-Baxter deformed AdS$_5\\times$S$^5$ backgrounds
Kyono, Hideki
2016-01-01
We proceed to study Yang-Baxter deformations of the AdS$_5\\times$S$^5$ superstring with the classical Yang-Baxter equation. We make a general argument on the supercoset construction and present the master formula to describe the dilaton in terms of classical $r$-matrices. The supercoset construction is explicitly performed for some classical $r$-matrices and the full backgrounds including the Ramond-Ramond (R-R) sector and dilaton are derived. Within the class of abelian $r$-matrices, the perfect agreement is shown for well-known examples including gravity duals of non-commutative gauge theories, $\\gamma$-deformations of S$^5$ and Schr\\"odinger spacetimes. It would be remarkable that the supercoset construction works well, even if the resulting backgrounds are not maximally supersymmetric. In particular, three-parameter $\\gamma$-deformations of S$^5$ and Schr\\"odinger spacetimes do not preserve any supersymmetries. As for non-abelian $r$-matrices, we will focus upon a specific example. The resulting backgroun...

Towards the gravity/CYBE correspondence beyond integrability — Yang-Baxter deformations of T1,1 —
Marcos Crichigno, P.; Matsumoto, Takuya; Yoshida, Kentaroh
2016-01-01
Yang-Baxter sigma models, proposed by Klimcik and Delduc-Magro-Vicedo, have been recognized as a powerful framework for studying integrable deformations of two dimensional non-linear sigma models. In this short article, as an important generalization, we review a non-integrable sigma model in the Yang-Baxter sigma model approach based on [arXiv:1406.2249]. In particular, we discuss a family of deformations of the 5D Sasaki-Einstein manifold T1,1, instead of the standard deformations of the 5-sphere S5. For this purpose, we first describe a novel construction of T1,1 as a supercoset, and provide a physical interpretation of this construction from viewpoint of the dual Klebanov-Witten field theory. Secondly, we consider a 3-parameter deformation of T1,1 by using classical r-matrices satisfying the classical Yang-Baxter equation (CYBE). The resulting metric and NS-NS two-form completely agree with the ones previously obtained via TsT (T-dual - shift - T-dual) transformations, and contain the Lunin-Maldacena background as a special case. Our result indicates that what we refer to as the gravity/CYBE(Classical Yang-Baxter Equation) correspondence can be extended beyond integrable cosets.
A general method of constructing spectral parameter-dependent solutions of the graded Yang-Baxter equation using quantum supergroups is briefly reviewed. Using this method, a quantum R-matrix associated with the vector representation of Uq(osp(M/2n)) is obtained for all M and n. (orig.)

Using the Kauffman-Lomonaco method, some two-qutrits universal quantum gates are derived from the nine-dimensional unitary solutions of the Yang-Baxter equations associated with algebraic structures like the partial transpose operator and the dihedral group, which admit three dimensional representations. The Yang-Baxterization method given by Zhang-Kauffman-Ge is continuously used to obtain two-qutrits quantum gates and certain Hamiltonians for the evolution of the quantum gates are obtained, being such Hamiltonians interpreted as physical Hamiltonians of chain of particles of spin 1. Finally, the generalization for systems of two qudits is presented in the case of Yang-Baxterization of representations of braided monoidal algebra like the BH algebra and the bicolored Birman-Wenzl-Muraki algebra. For these algebras the corresponding two-qudits quantum gates are constructed jointly with the associated Hamiltonians interpreted like physical chains of particles with spin d. It is conjectured that the derived two-qdits quantum gates and the Hamiltonians may be implemented over bi-dimensional lattice systems like anyons systems or more generally over any physical systems ruled by the Yang-Baxter equations.

Changes in life expectancy, healthy life expectancy and health seeking behaviour are having an impact on the demand for care. Such changes could occur across the whole population, or for specific groups. Changes for specific groups will be particularly affected by policy initiatives, while both these and wider changes will be affected by people's levels of engagement with their health and the health service itself. Levels of education, income and media coverage of health issues are also important. These factors could also encourage an increase in people caring for themselves and their families or community. People are now expecting a patient-centred service with safe high quality treatment, comfortable accommodation services, fast access and an integrated joined-up system. The uptake of integrated Information and Communication technologies (ICT) will be crucial. Healthcare Compunetics, the combination of computing and networking customised for medical and care, will provide the common policy and framework for combined multi-disciplinary research, development, implementation and usage.

Yang-Baxter equation, parameter permutations, and the elliptic beta integral
This paper presents a construction of an infinite-dimensional solution of the Yang-Baxter equation of rank 1 which is represented as an integral operator with an elliptic hypergeometric kernel acting in the space of functions of two complex variables. This R-operator intertwines the product of two standard L-operators associated with the Sklyanin algebra, an elliptic deformation of the algebra sl(2). The solution is constructed from three basic operators S1, S2, and S3 generating the permutation group S4 on four parameters. Validity of the key Coxeter relations (including a star-triangle relation) is based on the formula for computing an elliptic beta integral and the Bailey lemma associated with an elliptic Fourier transformation. The operators Sj are determined uniquely with the help of the elliptic modular double. Bibliography: 37 titles
Matched pairs approach to set theoretic solutions of the Yang-Baxter equation
We study set-theoretic solutions (X,r) of the Yang-Baxter equations on a set X in terms of the induced left and right actions of X on itself. We give a characterization of involutive square-free solutions in terms of cyclicity conditions. We characterise general solutions in terms of an induced matched pair of unital semigroups S(X,r) and construct (S,rS) from the matched pair. Finally, we study extensions of solutions in terms of matched pairs of their associated semigroups. We also prove several general results about matched pairs of unital semigroups of the required type, including iterated products S bowtie S bowtie S underlying the proof that rS is a solution, and extensions (S bowtie T, rSbowtieT). Examples include a general 'double' construction (S bowtie S,rSbowtieS) and some concrete extensions, their actions and graphs based on small sets. (author)
The Yang-Baxter equation for PT invariant nineteen vertex models
Pimenta, R A
2010-01-01
We study the solutions of the Yang-Baxter equation associated to nineteen vertex models invariant by the parity-time symmetry from the perspective of algebraic geometry. We determine the form of the algebraic curves constraining the respective Boltzmann weights and found that they possess a universal structure. This allows us to classify the integrable manifolds in four different families reproducing three known models besides uncovering a novel nineteen vertex model in a unified way. The introduction of the spectral parameter on the weights is made via the parameterization of the fundamental algebraic curve which is a conic. The diagonalization of the transfer matrix of the new vertex model and its thermodynamic limit properties are discussed. We point out a connection between the form of the main curve and the nature of the excitations of the corresponding spin-1 chains.

Baxter's Q-operators and operatorial Backlund flow for quantum (super)-spin chains
Kazakov, Vladimir; Tsuboi, Zengo
2010-01-01
We propose the operatorial form of Baxter's TQ-relations in a general form of the operatorial B\\"acklund flow describing the nesting process for the inhomogeneous rational gl(K|M) quantum (super)spin chains with twisted periodic boundary conditions. The full set of Q-operators and T-operators on all levels of nesting is explicitly defined. The results are based on a generalization of the identities among the group characters and their group co-derivatives with respect to the twist matrix, found by one of the authors and P.Vieira [V.Kazakov and P.Vieira, JHEP 0810 (2008) 050 [arXiv:0711.2470

We solve the longstanding problem to define a functional characterization of the spectrum of the transfer matrix associated to the most general spin-1/2 representations of the 6-vertex reflection algebra for general inhomogeneous chains. The corresponding homogeneous limit reproduces the spectrum of the Hamiltonian of the spin-1/2 open XXZ and XXX quantum chains with the most general integrable boundaries. The spectrum is characterized by a second order finite difference functional equation of Baxter type with an inhomogeneous term which vanishes only for some special but yet interesting non-diagonal boundary conditions. This functional equation is shown to be equivalent to the known separation of variable (SOV) representation hence proving that it defines a complete characterization of the transfer matrix spectrum. The polynomial character of the Q-function allows us then to show that a finite system of equations of generalized Bethe type can be similarly used to describe the complete transfer matrix spectru...
On discrete three-dimensional equations associated with the local Yang-Baxter relation
Kashaev, R. M.
1996-12-01
The local Yang-Baxter equation (YBE), introduced by Maillet and Nijhoff, is a proper generalization to three dimensions of the zero curvature relation. Recently, Korepanov has constructed an infinite set of integrable three-dimensional lattice models, and has related them to solutions to the local YBE. The simplest Korepanov model is related to the star-triangle relation in the Ising model. In this Letter the corresponding discrete equation is derived. In the continuous limit it leads to a differential three-dimensional equation, which is symmetric with respect to all permutations of the three coordinates. A similar analysis of the star-triangle transformation in electric networks leads to the discrete bilinear equation of Miwa, associated with the BKP hierarchy. Some related operator solutions to the tetrahedron equation are also constructed.

Homogeneous Yang-Baxter deformations as non-abelian duals of the AdS_5 sigma-model
Hoare, B
2016-01-01
We propose that the Yang-Baxter deformation of the symmetric space sigma-model parameterized by an r-matrix solving the homogeneous (classical) Yang-Baxter equation is equivalent to the non-abelian dual of the undeformed model with respect to a subgroup determined by the structure of the r-matrix. We explicitly demonstrate this on numerous examples in the case of the AdS_5 sigma-model. The same should also be true for the full AdS_5 x S^5 supercoset model, providing an explanation for and generalizing several recent observations relating homogeneous Yang-Baxter deformations based on non-abelian r-matrices to the undeformed AdS_5 x S^5 model by a combination of T-dualities and non-linear coordinate redefinitions. This also includes the special case of deformations based on abelian r-matrices, which correspond to TsT transformations: they are equivalent to non-abelian duals of the original model with respect to a central extension of abelian subalgebras.

Yang-Baxter sigma models, proposed by Klimcik and Delduc-Magro-Vicedo, have been recognized as a powerful framework for studying integrable deformations of two-dimensional non-linear sigma models. In this short article, as an important generalization, we review a non-integrable sigma model in the Yang-Baxter sigma model approach based on [arXiv:1406.2249]. In particular, we discuss a family of deformations of the 5D Sasaki-Einstein manifold $T^{1,1}$, instead of the standard deformations of the $5$-sphere S$^5$. For this purpose, we first describe a novel construction of $T^{1,1}$ as a supercoset, and provide a physical interpretation of this construction from viewpoint of the dual Klebanov-Witten field theory. Secondly, we consider a $3$-parameter deformation of $T^{1,1}$ by using classical $r$-matrices satisfying the classical Yang--Baxter equation (CYBE). The resulting metric and NS-NS two-form completely agree with the ones previously obtained via TsT (T-dual -- shift -- T-dual) transformations, and conta...

Manifestation of soil water repellency depends both on the surface chemistry and the physical structure of the particles making up the soil. In materials science the effect of physical structure on water repellency is often explained by the Cassie-Baxter equation. Recently, a few attempts have been made to explain water repellency of soil using the Cassie-Baxter equation for hexagonally-arrayed spheres on a flat plane. Experimental verification of this conceptual model using glass beads as model soil particles has been left somewhat incomplete, as the experimentally measured contact angles do not match well those expected from theory. This might be caused by a failure to generate a perfect arrangement of particles. Therefore, we have aimed to obtain highly precise arrangements of glass beads as model soil particles using 3D printing technology. Our aim is to generate particle frames of precise hexagonal arrangement with particles at differing separations, and to measure the water contact angles upon the particle arrays optically using a goniometer. In this contribution, we report our preliminary results in which we explore the applicability of the Cassie-Baxter equation to such regular arrays as both separation distance and surface roughness is varied. This research has been funded by Bridging the Gap in Swansea University, UK.

On the Hamiltonian integrability of the bi-Yang-Baxter sigma-model
Delduc, Francois; Magro, Marc; Vicedo, Benoit
2015-01-01
The bi-Yang-Baxter sigma-model is a certain two-parameter deformation of the principal chiral model on a real Lie group G for which the left and right G-symmetries of the latter are both replaced by Poisson-Lie symmetries. It was introduced by C. Klimcik who also recently showed it admits a Lax pair, thereby proving it is integrable at the Lagrangian level. By working in the Hamiltonian formalism and starting from an equivalent description of the model as a two-parameter deformation of the coset sigma-model on G x G / G_diag, we show that it also admits a Lax matrix whose Poisson bracket is of the standard r/s-form characterised by a twist function which we determine. A number of results immediately follow from this, including the identification of certain complex Poisson commuting Kac-Moody currents as well as an explicit description of the q-deformed symmetries of the model. Moreover, the model is also shown to fit naturally in the general scheme recently developed for constructing integrable deformations o...
Beyond Wenzel and Cassie-Baxter: second-order effects on the wetting of rough surfaces.
Hejazi, Vahid; Moghadam, Afsaneh Dorri; Rohatgi, Pradeep; Nosonovsky, Michael
2014-08-12
The Wenzel and Cassie-Baxter models are almost exclusively used to explain the contact angle dependence of the structure of rough and patterned solid surfaces. However, these two classical models do not always accurately predict the wetting properties of surfaces since they fail to capture the effect of many interactions occurring during wetting, including, for example, the effect of the disjoining pressure and of crystal microstructure, grains, and defects. We call such effects the second-order effects and present here a model showing how the disjoining pressure isotherm can affect wettability due to the formation of thin liquid films. We measure water contact angles on pairs of metallic surfaces with nominally the same Wenzel roughness obtained by abrasion and by chemical etching. These two methods of surface roughening result in different rough surface structure, thus leading to different values of the contact angle, which cannot be captured by the Wenzel- and Cassie-type models. The chemical and physical changes that occur on the stainless steel and aluminum alloy surfaces as a result of intergranular corrosion, along with selective intermetallic dissolution, lead to a surface roughness generated on the nano- and microscales.

[Results of primary healthcare].
Duponchel, J L
2004-01-01
The concept of primary healthcare was formulated at the international conference held in Alma-Ata (USSR) on September 6 to 12, 1978. Over the past quarter-century, the term "primary healthcare" has been widely used as a basis for implementing healthcare policies in various nations, especially those considered as developing countries. However many programs initiated in the name of the primary healthcare concept have only partially complied with the spirit of the final declaration of Alma-Ata. Analysis of the healthcare in Mali shows that the system followed that evolution. Although considerable time and energy were regrettably wasted in implementing the village health agent strategy, this phase may have been a necessary step in the political development of the state at that time. Recent changes in the country's healthcare system in compliance with the original principles of primary healthcare show that the 1978 declaration is sound and remains pertinent as democracy makes further gains in the world.

Taiwan's healthcare report 2010.
Ho Chan, Willie Sai
2010-12-01
Times are changing. Taiwan is one of the richest countries in the Asia Pacific region. It enacted its single-payer national health insurance program in 1995: in all estimates, it has been very successful. It has a strong healthcare system and the universal health insurance ensures that all citizens have grown to expect a high level of care. Healthcare systems are designed to meet the healthcare needs of target populations. There are a wide variety of healthcare systems around the world. In some countries, healthcare system planning is distributed among market participants, whereas in others planning is made more centrally among governments, trade unions, charities, religions, or other co-ordinated bodies to deliver planned healthcare services targeted to the populations they serve. However, healthcare planning has often been evolutionary rather than revolutionary. In healthcare all work carried out must be at the highest quality, and a much higher proportion of resources must be invested in quality in healthcare. The aim of this report is to give an overview of the healthcare service provision in Taiwan. PMID:23199110

Why healthcare providers merge.
Postma, Jeroen; Roos, Anne-Fleur
2016-04-01
In many OECD countries, healthcare sectors have become increasingly concentrated as a result of mergers. However, detailed empirical insight into why healthcare providers merge is lacking. Also, we know little about the influence of national healthcare policies on mergers. We fill this gap in the literature by conducting a survey study on mergers among 848 Dutch healthcare executives, of which 35% responded (resulting in a study sample of 239 executives). A total of 65% of the respondents was involved in at least one merger between 2005 and 2012. During this period, Dutch healthcare providers faced a number of policy changes, including increasing competition, more pressure from purchasers, growing financial risks, de-institutionalisation of long-term care and decentralisation of healthcare services to municipalities. Our empirical study shows that healthcare providers predominantly merge to improve the provision of healthcare services and to strengthen their market position. Also efficiency and financial reasons are important drivers of merger activity in healthcare. We find that motives for merger are related to changes in health policies, in particular to the increasing pressure from competitors, insurers and municipalities. PMID:26055501
A non-symmetric Yang–Baxter algebra for the quantum nonlinear Schrödinger model
We study certain non-symmetric wavefunctions associated with the quantum nonlinear Schrödinger model, introduced by Komori and Hikami using Gutkin’s propagation operator, which involves representations of the degenerate affine Hecke algebra. We highlight how these functions can be generated using a vertex-type operator formalism similar to the recursion defining the symmetric (Bethe) wavefunction in the quantum inverse scattering method. Furthermore, some of the commutation relations encoded in the Yang–Baxter equation for the relevant monodromy matrix are generalized to the non-symmetric case. (paper)
We study the critical properties of the weakly disordered two-dimensional sing and Baxter models in terms of the renormalization group (RG) theory generalized to take into account replica symmetry breaking (RSB) effects. Recently it has been shown that the traditional replica-symmetric RG flows in the dimension D=4-ε are unstable with respect to the RSB potentials and a new spin-glass type critical phenomena has been discovered (Dotsenko Vik S, Harris B, Sherrington D and Stinchbombe R 1995 J. Phys. A: Math. Gen. 8 3093; Dotsenko Vik S and Feldman D E 1995 J. Phys. A: Math. Gen. 28 5183). In contrast, here it is demonstrated that in the considered two-dimensional systems the renormalization-group flows are stable with respect to the RSB modes. It is shown that the solution of the renormalization group equations with arbitrary starting RSB coupling matrix exhibits asymptotic approach to the traditional replica-symmetric ones. Thus, to leading order the on-perturbative RSB degrees of freedom do not affect the critical phenomena in the two-dimensional weakly disordered Ising and Baxter models studied earlier. (author)

Improving healthcare practice behaviors.
Van Fleet, David D; Peterson, Tim O
2016-03-14
Purpose - The purpose of this paper is to present the results of exploratory research designed to develop an awareness of healthcare behaviors, with a view toward improving the customer satisfaction with healthcare services. It examines the relationship between healthcare providers and their consumers/patients/clients. Design/methodology/approach - The study uses a critical incident methodology, with both effective and ineffective behavioral specimens examined across different provider groups. Findings - The effects of these different behaviors on what Berry (1999) identified as the common core values of service organizations are examined, as those values are required to build a lasting service relationship. Also examined are categories of healthcare practice based on the National Quality Strategy priorities. Research limitations/implications - The most obvious is the retrospective nature of the method used. How accurate are patient or consumer memories? Are they capable of making valid judgments of healthcare experiences (Berry and Bendapudi, 2003)? While an obvious limitation, such recollections are clearly important as they may be paramount in following the healthcare practitioners' instructions, loyalty for repeat business, making recommendations to others and the like. Further, studies have shown retrospective reports to be accurate and useful (Miller et al., 1997). Practical implications - With this information, healthcare educators should be in a better position to improve the training offered in their programs and practitioners to better serve their customers. Social implications - The findings would indicate that the human values of excellence, innovation, joy, respect and integrity play a significant role in building a strong service relationship between consumer and healthcare provider. Originality/value - Berry (1999) has argued that the overriding importance in building a lasting service business is human values. This exploratory study has shown how

Coproduction of healthcare service.
Batalden, Maren; Batalden, Paul; Margolis, Peter; Seid, Michael; Armstrong, Gail; Opipari-Arrigan, Lisa; Hartung, Hans
2016-07-01
Efforts to ensure effective participation of patients in healthcare are called by many names-patient centredness, patient engagement, patient experience. Improvement initiatives in this domain often resemble the efforts of manufacturers to engage consumers in designing and marketing products. Services, however, are fundamentally different than products; unlike goods, services are always 'coproduced'. Failure to recognise this unique character of a service and its implications may limit our success in partnering with patients to improve health care. We trace a partial history of the coproduction concept, present a model of healthcare service coproduction and explore its application as a design principle in three healthcare service delivery innovations. We use the principle to examine the roles, relationships and aims of this interdependent work. We explore the principle's implications and challenges for health professional development, for service delivery system design and for understanding and measuring benefit in healthcare services.

Advances in wireless technology give pace to the rapid development of mobile applications. The coming mobile revolution will bring dramatic and fundamental changes to our daily life. It will influence the way we live, the way we do things, and the way we take care of our health. For the healthcare industry, mobile applications provide a new frontier in offering better care and services to patients, and a more flexible and mobile way of communicating with suppliers and patients. Mobile applications will provide important real time data for patients, physicians, insurers, and suppliers. In addition, it will revolutionalize the way information is managed in the healthcare industry and redefine the doctor - patient communication. This paper discusses different aspects of mobile healthcare. Specifically, it presents mobile applications in healthcare, and discusses possible challenges facing the development of mobile applications. Obstacles in developing mobile healthcare applications include mobile device limitations, wireless networking problems, infrastructure constraints, security concerns, and user distrust. Research issues in resolving or alleviating these problems are also discussed in the paper. PMID:16777784

Patient queues are prevalent in healthcare and wait time is one measure of access to care. We illustrate Queueing Theory-an analytical tool that has provided many insights to service providers when designing new service systems and managing existing ones. This established theory helps us to quantify the appropriate service capacity to meet the patient demand, balancing system utilization and the patient's wait time. It considers four key factors that affect the patient's wait time: average patient demand, average service rate and the variation in both. We illustrate four basic insights that will be useful for managers and doctors who manage healthcare delivery systems, at hospital or department level. Two examples from local hospitals are shown where we have used queueing models to estimate the service capacity and analyze the impact of capacity configurations, while considering the inherent variation in healthcare.

Characteristics of healthcare wastes.
Diaz, L F; Eggerth, L L; Enkhtsetseg, Sh; Savage, G M
2008-01-01
A comprehensive understanding of the quantities and characteristics of the material that needs to be managed is one of the most basic steps in the development of a plan for solid waste management. In this case, the material under consideration is the solid waste generated in healthcare facilities, also known as healthcare waste. Unfortunately, limited reliable information is available in the open literature on the quantities and characteristics of the various types of wastes that are generated in healthcare facilities. Thus, sound management of these wastes, particularly in developing countries, often is problematic. This article provides information on the quantities and properties of healthcare wastes in various types of facilities located in developing countries, as well as in some industrialized countries. Most of the information has been obtained from the open literature, although some information has been collected by the authors and from reports available to the authors. Only data collected within approximately the last 15 years and using prescribed methodologies are presented. The range of hospital waste generation (both infectious and mixed solid waste fractions) varies from 0.016 to 3.23kg/bed-day. The relatively wide variation is due to the fact that some of the facilities surveyed in Ulaanbaatar include out-patient services and district health clinics; these facilities essentially provide very basic services and thus the quantities of waste generated are relatively small. On the other hand, the reported amount of infectious (clinical, yellow bag) waste varied from 0.01 to 0.65kg/bed-day. The characteristics of the components of healthcare wastes, such as the bulk density and the calorific value, have substantial variability. This literature review and the associated attempt at a comparative analysis point to the need for worldwide consensus on the terms and characteristics that describe wastes from healthcare facilities. Such a consensus would greatly

Full Text Available BackgroundSocial marketing is an important tool in the delivery ofhealthcare services. For any healthcare programme orproject to be successful, community/consumer participationis required. The four principles of social marketing can guidepolicymakers and healthcare providers to successfully planand implement health programmes.AimTo review the existing literature in order to project thebenefits of social marketing in healthcare.MethodA search of periodical literature by the author involvingsocial marketing and marketing concepts in health wascarried out. Items were identified initially through healthorientedindexing services such as Medline, Health STARand Cinahl, using the identifiers “social marketing“ and“marketing in health”. An extensive search was also carriedout on educational database ERIC.ResultsA literature review of various studies on social marketingindicated that the selection of the right product (accordingto the community need at the right place, with the rightstrategy for promotion and at the right price yields goodresults. However, along with technical sustainability(product, price, promotion and place, financialsustainability, institutional sustainability and marketsustainability are conducive factors for the success of socialmarketing.ConclusionThe purpose of this literature review was to ascertain thelikely effectiveness of social marketing principles andapproaches and behaviour change communication towardshealth promotion.It is important for all healthcare workers to understand andrespond to the public’s desires and needs and routinely useconsumer research to determine how best to help thepublic to solve problems and realise aspirations. Socialmarketing can optimise public health by facilitatingrelationship-building with consumers and making their liveshealthier.

Based on the formulation of Yang-Baxter sigma models developed by Klimcik and Delduc-Magro-Vicedo, we explain that various deformations of type IIB superstring on AdS5 × S5 can be charactered by classical r-matrices satisfying the classical Yang-Baxter equation (CYBE). The relation may be referred to as the gravity/CYBE correspondence. We present non-trivial examples of the correspondence including Lunin-Maldacena backgrounds for β-deformations of the N = 4 super Yang-Mills theory and the gravity duals for non-commutative gauge theories. We also discuss non-integrable backgrounds such as AdS5 × T1,1 as a generalization

Migrants' access to healthcare.
Norredam, Marie
2011-10-01
There are strong pragmatic and moral reasons for receiving societies to address access to healthcare for migrants. Receiving societies have a pragmatic interest in sustaining migrants' health to facilitate integration; they also have a moral obligation to ensure migrants' access to healthcare according to international human rights principles. The intention of this thesis is to increase the understanding of migrants' access to healthcare by exploring two study aims: 1) Are there differences in migrants' access to healthcare compared to that of non-migrants? (substudy I and II); and 2) Why are there possible differences in migrants' access to healthcare compared to that of non-migrants? (substudy III and IV). The thesis builds on different methodological approaches using both register-based retrospective cohort design, cross-sectional design and survey methods. Two different measures of access were used to explore differences: 1) cancer stage at diagnosis as a clinical outcome and 2) emergency room (ER) contacts as a utilisation measure. Both informal and formal barriers to access were studied to explore why possible differences existed including: 1) motivation for using ER; and 2) asylum seekers' healthcare entitlements. Different definitions of migration and ethnicity were investigated including: country of birth and residence status. Substudy I showed a tendency towards more advanced stage at diagnosis or unknown stage among most subgroups of migrant women with a history of cancer compared to non-migrant women. Sub-study II found that some migrants (those born in Somalia, Turkey and Ex-Yugoslavia) use ER services more frequently than do non-migrants whereas others have the same or lower utilisation levels. As a consequence, substudy III was undertaken, which documented that more migrant within all subgroups had considered contacting a primary caregiver before visiting the ER compared to non-migrants, but that migrants experienced communication problems herein
[Healthcare value chain: a model for the Brazilian healthcare system].
Pedroso, Marcelo Caldeira; Malik, Ana Maria
2012-10-01
This article presents a model of the healthcare value chain which consists of a schematic representation of the Brazilian healthcare system. The proposed model is adapted for the Brazilian reality and has the scope and flexibility for use in academic activities and analysis of the healthcare sector in Brazil. It places emphasis on three components: the main activities of the value chain, grouped in vertical and horizontal links; the mission of each link and the main value chain flows. The proposed model consists of six vertical and three horizontal links, amounting to nine. These are: knowledge development; supply of products and technologies; healthcare services; financial intermediation; healthcare financing; healthcare consumption; regulation; distribution of healthcare products; and complementary and support services. Four flows can be used to analyze the value chain: knowledge and innovation; products and services; financial; and information. PMID:23099762

Innovation Concepts in Healthcare
CERN. Geneva
2010-01-01
AbstractDemographic change and advances in medical science pose increased challenges to healthcare systems globally: The economic basis is aging and thus health is becoming more and more a productivity factor. At the same time, with today’s new communication possibilities the demand and expectations of effective medical treatment have been increased. This presentation will illustrate the need for the “industrialization” of healthcare in order to achieve highest results at limited budgets. Thereby, industrialization is not meaning the medical treatment based on the assembly line approach. Rather it is to recognize the cost of medical care as an investment with respective expectations on the return of the investment. Innovations in imaging and pharmaceutical products as well as in processes - that lead to similar medical results, but with lower efforts - are keys in such scenarios.BiographyProf. Dr. Hermann Requardt, 54, is a member of the Managing Board of Siemens AG and Chief Executive Officer of the He...

Myanmar transitioned to a civilian government in March, 2011. Although the democratic process has accelerated since then, many problems in the field of healthcare still exist. Since there is a limited overview on the healthcare in Myanmar, this article briefly describes the current states surrounding health services in Myanmar. According to the Census 2014, the population in the Republic of the Union of Myanmar was 51,410,000. The crude birth rate in the previous one year was estimated to be 18.9 per 1,000, giving the annual population growth rate of 0.89% between 2003 and 2014. The Ministry of Health reorganized into six departments. National non-governmental organizations and community-based organizations support healthcare, as well as international non-governmental organizations. Since hospital statistics by the government cover only public facilities, the information on private facilities is limited. Although there were not enough medical doctors (61 per 100,000 population), the number of medical students was reduced from 2,400 to 1,200 in 2012 to ensure the quality of medical education. The information on causes of death in the general population could not be retrieved, but some data was available from hospital statistics. Although the improvement was marked, the figures did not reach the levels set by Millennium Development Goals 4 and 5. A trial prepaid health insurance system started in July 2015, to be followed by evaluation one year later. There are many international donors, including the Japan International Cooperation Agency, supporting health in Myanmar. With these efforts and support, a marked progress is expected in the field of healthcare. PMID:27303099

Improving Healthcare through Lean Management
Nielsen, Anders Paarup; Edwards, Kasper
2011-01-01
The ideas and principles from lean management are now widely being adopted within the healthcare sector. The analysis in this paper shows that organizations within healthcare most often only implement a limited set of tools and methods from the lean tool-box. Departing from a theoretical analysis...... of the well-known and universal lean management principles in the context of the healthcare this paper will attempt to formulate and test four hypotheses about possible barriers to the successful implementation of lean management in healthcare. The first hypothesis states that lean management in...... healthcare still is in its infancy and it is just a matter of letting sufficient time pass in order have a successful implementation of lean in all areas of healthcare. The second hypothesis states that a major barrier to lean management in healthcare simply is lacking understanding of the lean concepts...
On q-deformed symmetries as Poisson-Lie symmetries and application to Yang-Baxter type models
Delduc, Francois; Magro, Marc; Vicedo, Benoit
2016-01-01
Yang-Baxter type models are integrable deformations of integrable field theories, such as the principal chiral model on a Lie group $G$ or $\\sigma$-models on (semi-)symmetric spaces $G/F$. The deformation has the effect of breaking the global $G$-symmetry of the original model, replacing the associated set of conserved charges by ones whose Poisson brackets are those of the $q$-deformed Poisson-Hopf algebra $\\mathscr U_q(\\mathfrak g)$. Working at the Hamiltonian level, we show how this $q$-deformed Poisson algebra originates from a Poisson-Lie $G$-symmetry. The theory of Poisson-Lie groups and their actions on Poisson manifolds, in particular the formalism of the non-abelian moment map, is reviewed. For a coboundary Poisson-Lie group $G$, this non-abelian moment map must obey the Semenov-Tian-Shansky bracket on the dual group $G^*$, up to terms involving central quantities. When the latter vanish, we develop a general procedure linking this Poisson bracket to the defining relations of the Poisson-Hopf algebra...
Factorized three-body S-matrix restrained by the Yang–Baxter equation and quantum entanglements
This paper investigates the physical effects of the Yang–Baxter equation (YBE) to quantum entanglements through the 3-body S-matrix in entangling parameter space. The explicit form of 3-body S-matrix Ř123(θ,φ) based on the 2-body S-matrices is given due to the factorization condition of YBE. The corresponding chain Hamiltonian has been obtained and diagonalized, also the Berry phase for 3-body system is given. It turns out that by choosing different spectral parameters the Ř(θ,φ)-matrix gives GHZ and W states respectively. The extended 1-D Kitaev toy model has been derived. Examples of the role of the model in entanglement transfer are discussed. - Highlights: • We give the relation between 3-body S-matrix and 3-qubit entanglement. • The relation between 3-qubit and 2-qubit entanglements is investigated via YBE. • 1D Kitaev toy model is derived by the Type-II solution of YBE. • The condition of YBE kills the “Zero boundary mode” in our chain model
Regional Healthcare Effectiveness

Full Text Available An evaluation of healthcare systems effectiveness of the regions of the Russian Federation (federal districts was conducted using the Minmax method based on the data available at the United Interdepartmental Statistical Information System. Four groups of components (i.e. availability of resources; use of resources; access to resources and medical effectiveness decomposed into 17 items were analyzed. The resource availability was measured by four indicators, including the provision of doctors, nurses, hospital beds; agencies providing health care to the population. Use of resources was measured by seven indicators: the average hospital stay, days; the average bed occupancy, days; the number of operations per 1 physician surgical; the cost per unit volume of medical care: in outpatient clinics, day hospitals, inpatient and emergency care. Access to the resources was measured by three indicators: the satisfaction of the population by medical care; the capacity of outpatient clinics; the average number of visits to health facility. The medical effectiveness was also measured by three indicators: incidence with the "first-ever diagnosis of malignancy"; life expectancy at birth, years; the number of days of temporary disability. The study of the dynamics of the components and indexes for 2008–2012 allows to indicate a multidirectional influence on the regional healthcare system. In some federal districts (e.g. North Caucasian, the effectiveness decreases due to resource availability, in others (South, North Caucasian — due to the use of resources, in others (Far Eastern, Ural — due to access to resources. It is found that the effectiveness of the healthcare systems of the federal districts differs significantly. In addition, the built matrix proves the variability the of effectiveness (comparison of expenditures and results of healthcare systems of the federal districts of the Russian Federation: the high results can be obtained at high costs
Data mining applications in healthcare.
Koh, Hian Chye; Tan, Gerald
2005-01-01
Data mining has been used intensively and extensively by many organizations. In healthcare, data mining is becoming increasingly popular, if not increasingly essential. Data mining applications can greatly benefit all parties involved in the healthcare industry. For example, data mining can help healthcare insurers detect fraud and abuse, healthcare organizations make customer relationship management decisions, physicians identify effective treatments and best practices, and patients receive better and more affordable healthcare services. The huge amounts of data generated by healthcare transactions are too complex and voluminous to be processed and analyzed by traditional methods. Data mining provides the methodology and technology to transform these mounds of data into useful information for decision making. This article explores data mining applications in healthcare. In particular, it discusses data mining and its applications within healthcare in major areas such as the evaluation of treatment effectiveness, management of healthcare, customer relationship management, and the detection of fraud and abuse. It also gives an illustrative example of a healthcare data mining application involving the identification of risk factors associated with the onset of diabetes. Finally, the article highlights the limitations of data mining and discusses some future directions. PMID:15869215

SOA governance in healthcare organisations.
Koumaditis, Konstantinos; Themistocleous, Marinos; Vassilakopoulos, Georgios
2013-01-01
Service Oriented Architecture (SOA) is increasingly adopted by many sectors, including healthcare. Due to the nature of healthcare systems there is a need to increase SOA adoption success rates as the non integrated nature of healthcare systems is responsible for medical errors that cause the loss of tens of thousands patients per year. Following our previous research [1] we propose that SOA governance is a critical success factor for SOA success in healthcare. Literature reports multiple SOA governance models that have limitations and they are confusing. In addition to this, there is a lack of healthcare specific SOA governance models. This highlights a literature void and thus the purpose of this paper is to proposed a healthcare specific SOA governance framework. PMID:23823423

[The primary healthcare centres].
Brambilla, Antonio; Maciocco, Gavino
2014-04-01
The central attributes of primary care are: first contact (accessibility), longitudinality (person- focused preventive and curative care overtime), patient-oriented comprehensiveness and coordination (including navigation towards secondary and tertiary care). Besides taking care of the needs of the individuals, primary health care teams are also looking at the community, especially when addressing social determinants of health. The rationale for the benefits for primary care for health has been found in: 1) greater access to needed services; 2) better quality of care; 3) a greater focus on prevention; 4) early management of health problems; 5) organizing and delivering high quality care for chronic non-communicable diseases. This paper describes the role of primary healthcare centres in strengthening community primary services and in reducing health inequalities. Furthemore, the experiences of Regional Health Services from Tuscany and Emilia-Romagna are discussed, with a brief overview of the literature. PMID:24770539
Technology and healthcare costs
Kumar R
2011-01-01
Full Text Available Medicine in the 21 st century is increasingly dependent on technology. Unlike in many other areas, the cost of medical technology is not declining and its increasing use contributes to the spiraling healthcare costs. Many medical professionals equate progress in medicine to increasing use of sophisticated technology that is often expensive and beyond the reach of the average citizen. Pediatric heart care is very technology-intensive and therefore very expensive and beyond the reach of the vast majority of children in the developing world. There is an urgent need to address this situation through development and use of appropriate technology in accordance with the needs and priorities of the society. A number of simple and inexpensive quality measures that have the potential of improving outcomes substantially without the need for expensive equipment should be instituted before embracing high-end technology. Innovations to reduce costs that are commonly used in limited resource environments should be tested systematically.
Governance mechanisms for healthcare apps
Manikas, Konstantinos; Hansen, Klaus Marius; Kyng, Morten
2014-01-01
The introduction of the `app store' concept has challenged the way software is distributed and marketed: developers have easier access to customers, while customers have easy access to innovative applications. Apps today are increasingly focusing on more "mission-critical" areas like healthcare...... with the Apple AppStore counting more than 40,000 apps under the category "health & fitness". This rapid development of healthcare apps increases the necessity of governance as, currently, healthcare apps are not thoroughly governed. The U.S. Food and Drug Administration and the European Commission...... only have policies for apps that are medical devices.In this paper, we approach the problem of how to govern healthcare and medical apps by addressing the risks the use of these apps pose, while at the same time inviting for development of new apps. To do so we (i) analyze four cases of healthcare app...

MARKETING PLANNING IN HEALTHCARE INDUSTRY
Bobeica Ana Amaria
2013-04-01
Full Text Available The purpose of this paper is to develop a perspective on what is important or critical to the discipline of healthcare marketing by analyzing the marketing plan from the institutional (or organizational perspective. This “salience issue” is complicated by the structural problems in healthcare such as new advertising programs, advances in medical technology, and the escalating costs of care in the recent economic situation of world economic crisis. Reviewing a case study, the paper examines how marketing managers face increasingly difficult management and it emphasizes one more time the importance of marketing in the internal organizational structure. Also it shows the direct connection between the marketing strategy, the Quality of Healthcare and marketing planning in the internal organization of Private Healthcare Practice in Romania. Also it concludes that marketing planning in healthcare has to be very precised in order to achieve some major objectives: customer care, financial stability, equilibrium between stakeholders and shareholders and future improvement in communication to customers. The marketing strategies and programs discussed in this paper follow the analysis of the 4Ps of Healthcare Marketing Services and propose call to action plans and possibilities that might result in a more particular case study analysis of the Romanian Healthcare Market.

Improving healthcare using Lean processes.
Baker, G Ross
2014-01-01
For more than a decade, healthcare organizations across Canada have been using Lean management tools to improve care processes, reduce preventable adverse events, increase patient satisfaction and create better work environments. The largest system-wide effort in Canada, and perhaps anywhere, is currently under way in Saskatchewan. The jury is still out on whether Lean efforts in that province, or elsewhere in Canada, are robust enough to transform current delivery systems and sustain new levels of performance. This issue of Healthcare Quarterly features several articles that provide a perspective on Lean methods in healthcare. PMID:25191802
PUBLIC FINANCING OF HEALTHCARE SERVICES
Agnieszka Bem
2013-10-01
Full Text Available Healthcare in Poland is mainly financed by public sector entities, among them the National Health Fund (NFZ, state budget and local government budgets. The task of the National Health Fund, as the main payer in the system, is chiefly currently financing the services. The state budget plays a complementary role in the system, and finances selected groups of services, health insurance premiums and investments in healthcare infrastructure. The basic role of the local governments is to ensure access to the services, mostly by performing ownership functions towards healthcare institutions.

If the "old economy" preached standardization of products/services in order to reduce costs, the "new economy" is based on the recognition of the needs and the management of information. It is aimed at providing better and more usable services. One scenario is a national health service with regional management but based on competition between hospitals/companies.This led to a different handling of the user/patient, which has become the center of the health system: marketing seeks to retain the patient, trying to push a client-patient to not change their healthcare service provider. In costs terms, it is more economical to retain a customer rather than acquire a new one: a satisfied customer is also the best sounding board for each company. Customer equity is the management of relations with patients which can result in a greater customer value: it is possible to recognize an equity of the value, of the brand and of the report. Loyalty uses various marketing activities (basic, responsive, responsible, proactive and collaborative): each hospital/company chooses different actions depending on how many resources it plans to invest in loyalty.

Healthcare costs for new technologies
Goyen, Mathias; Debatin, Joerg F. [University Medical Center Hamburg-Eppendorf, Hamburg (Germany)
2009-03-15
Continuous ageing of the population coupled with growing health consciousness and continuous technological advances have fueled the rapid rise in healthcare costs in the United States and Europe for the past several decades. The exact impact of new medical technology on long-term spending growth remains the subject of controversy. By all measures it is apparent that new medical technology is the dominant driver of increases in health-care costs and hence insurance premiums. This paper addresses the impact of medical technology on healthcare delivery systems with regard to medical practice and costs. We first explore factors affecting the growth of medical technology and then attempt to provide a means for assessing the effectiveness of medical technology. Avoidable healthcare cost drivers are identified and related policy issues are discussed. (orig.)

Healthcare costs for new technologies
Continuous ageing of the population coupled with growing health consciousness and continuous technological advances have fueled the rapid rise in healthcare costs in the United States and Europe for the past several decades. The exact impact of new medical technology on long-term spending growth remains the subject of controversy. By all measures it is apparent that new medical technology is the dominant driver of increases in health-care costs and hence insurance premiums. This paper addresses the impact of medical technology on healthcare delivery systems with regard to medical practice and costs. We first explore factors affecting the growth of medical technology and then attempt to provide a means for assessing the effectiveness of medical technology. Avoidable healthcare cost drivers are identified and related policy issues are discussed. (orig.)

2016-01-01
Purpose - The purpose of this study is to evaluate how LEAN thinking is used as a management and development tool in the Finnish public healthcare system and what kind of outcomes have been achieved or expected by using it. The main focus is in managing and developing patient and treatment processes. Design/methodology/approach - A mixed-method approach incorporating the Webropol survey was used. Findings - LEAN is quite a new concept in Finnish public healthcare. It is mainly used as a development tool to seek financial savings and to improve the efficiency of patient processes, but has not yet been deeply implemented. However, the experiences from LEAN initiatives have been positive, and the methodology is already quite well-known. It can be concluded that, because of positive experiences from LEAN, the environment in Finnish healthcare is ready for the deeper implementation of LEAN. Originality/value - This paper evaluates the usage of LEAN thinking for the first time in the public healthcare system of Finland as a development tool and a management system. It highlights the implementation and achieved results of LEAN thinking when used in the healthcare environment. It also highlights the expectations for LEAN thinking in Finnish public healthcare.

HEALTHCARE: A COMPLEX SERVICE SYSTEM
James M. TIEN; Pascal J. GOLDSCHMIDT-CLERMONT
2009-01-01
Healthcare is indeed a complex service system, one requiring the technobiology approach of systems engineering to underpin its development as an integrated and adaptive system. In general, healthcare services are carried out with knowledge-intensive agents or components which work together as providers and consumers to create or co-produce value. Indeed, the engineering design of a healthcare system must recognize the fact that it is actually a complex integration of human-centered activities that is increasingly dependent on information technology and knowledge. Like any service system, healthcare can be considered to be a combination or recombination of three essential components-people (characterized by behaviors, values, knowledge, etc.), processes (characterized by collaboration, customization, etc.) and products (characterized by software, hardware, infrastructures, etc.). Thus, a healthcare system is an integrated and adaptive set of people, processes and products. It is, in essence, a system of systems which objectives are to enhance its efficiency (leading to greater interdependency) and effectiveness (leading to improved health). Integration occurs over the physical, temporal, organizational and functional dimensions, while adaptation occurs over the monitoring, feedback, cybernetic and learning dimensions. In sum, such service systems as healthcare are indeed complex, especially due to the uncertainties associated with the human-centered aspects of these systems. Moreover, the system complexities can only be dealt with methods that enhance system integration and adaptation.
Healthcare waste management in Asia
The risks associated with healthcare waste and its management has gained attention across the world in various events, local and international forums and summits. However, the need for proper healthcare waste management has been gaining recognition slowly due to the substantial disease burdens associated with poor practices, including exposure to infectious agents and toxic substances. Despite the magnitude of the problem, practices, capacities and policies in many countries in dealing with healthcare waste disposal, especially developing nations, is inadequate and requires intensification. This paper looks upon aspects to drive improvements to the existing healthcare waste management situation. The paper places recommendation based on a 12 country study reflecting the current status. The paper does not advocate for any complex technology but calls for changes in mindset of all concerned stakeholders and identifies five important aspects for serious consideration. Understanding the role of governments and healthcare facilities, the paper also outlines three key areas for prioritized action for both parties - budget support, developing policies and legislation and technology and knowledge management.
The Microbiome and Sustainable Healthcare
Rodney R. Dietert
2015-03-01
Full Text Available Increasing prevalences, morbidity, premature mortality and medical needs associated with non-communicable diseases and conditions (NCDs have reached epidemic proportions and placed a major drain on healthcare systems and global economies. Added to this are the challenges presented by overuse of antibiotics and increased antibiotic resistance. Solutions are needed that can address the challenges of NCDs and increasing antibiotic resistance, maximize preventative measures, and balance healthcare needs with available services and economic realities. Microbiome management including microbiota seeding, feeding, and rebiosis appears likely to be a core component of a path toward sustainable healthcare. Recent findings indicate that: (1 humans are mostly microbial (in terms of numbers of cells and genes; (2 immune dysfunction and misregulated inflammation are pivotal in the majority of NCDs; (3 microbiome status affects early immune education and risk of NCDs, and (4 microbiome status affects the risk of certain infections. Management of the microbiome to reduce later-life health risk and/or to treat emerging NCDs, to spare antibiotic use and to reduce the risk of recurrent infections may provide a more effective healthcare strategy across the life course particularly when a personalized medicine approach is considered. This review will examine the potential for microbiome management to contribute to sustainable healthcare.

The McCormick and Baxter Creosoting site is located on the Willamette River in Portland, Oregon. ATSDR considers the site to have been a public health hazard for former plant workers because of past ingestion exposure to arsenic, creosote, pentachlorophenol, polychlorinated dibenzodioxins, and dibenzofurans at levels of public health concern. The site also poses an ongoing and future public health hazard because people might encounter hazardous chemicals along the shoreline on or near the site at levels that can damage the skin, as was reported to have happened to two boys. Finally, dioxin levels would pose a public health hazard if people subsist on crayfish and suckers contaminated with polychlorinated dibenzodioxins and dibenzofurans.

We develop the Baxterization approach to (an extension of) the quantum group GL{sub q}(2). We introduce two matrices which play the role of spectral parameter dependent L-matrices and observe that they are naturally related to two different comultiplications. Using these comultiplication structures, we find the related fundamental R-operators in terms of powers of coproducts and also give their equivalent forms in terms of quantum dilogarithms. The corresponding quantum local Hamiltonians are given in terms of logarithms of positive operators. An analogous construction is developed for the q-oscillator and Weyl algebras using that their algebraic and coalgebraic structures can be obtained as reductions of those for the quantum group. As an application, the lattice Liouville model, the q-DST model, the Volterra model, a lattice regularization of the free field, and the relativistic Toda model are considered. (orig.)

The term “Healthcare Engineering” has been used by professional societies, universities, scientific authors, and the healthcare industry for decades. However, the definition of “Healthcare Engineering” remains ambiguous. The purpose of this position paper is to present a definition of Healthcare Engineering as an academic discipline, an area of research, a field of specialty, and a profession. Healthcare Engineering is defined in terms of what it is, who performs it, where it is performed, and how it is performed, including its purpose, scope, topics, synergy, education/training, contributions, and prospects.
[Patients' increasing role in healthcare].
Colombo, Cinzia
2016-03-01
Since the late '90s citizens have been increasingly involved in healthcare, thanks to a shift in access to healthcare information, greater patients' and citizens' awareness about their rights and needs, and a change in physicians' attitudes and behavior. At the same time, to ensure the sustainability of the national health services, patients' needs are increasingly being examined in relation to the services and interventions needed, and to foster informed demand by patients and citizens, and appropriate prescriptions by physicians. Nowadays, patients already have a section in an authoritative medical journal. Working with clinicians, they set research priorities and the outcomes to be studied. Especially in UK and USA, they are invited to participate in the design and development of trials and in deciding which trials should be funded. The situation varies widely in different countries, though involving citizens in healthcare decisions is a common mantra. Even when they consult a clinician, the patients' role has evolved. People ask for information more often and want an active part in decisions about their health. Physicians start to pay more attention to the person and the social context, feelings and emotions, and person-centered care has become a reference in the doctor-patient relationship. This article offers an overview of the changing roles of patients and citizens in healthcare. PMID:27030220

Control of corruption in healthcare.
Ahmed, Armin; Azim, Afzal
2015-01-01
A recently published article on corruption in Indian healthcare in the BMJ has triggered a hot debate and numerous responses (1, 2, 3, 4). We do agree that corruption in Indian healthcare is a colossal issue and needs to be tackled urgently (5). However, we want to highlight that corruption in healthcare is not a local phenomenon confined to the Indian subcontinent, though India does serve as a good case study and intervention area due to the magnitude of the problem and the country's large population (6). Good governance, strict rules, transparency and zero tolerance are some of the strategies prescribed everywhere to tackle corruption. However, those entrusted with implementing good governance and strict rules in India need to go through a process of introspection to carry out their duties in a responsible fashion. At present, it looks like a no-win situation. In this article, we recommend education in medical ethics as the major intervention for dealing with corruption in healthcare. PMID:26592785

Performance indicators: healthcare professionals' views.
Gu, Xiuzhu; Itoh, Kenji
2016-08-01
Purpose - The purpose of this paper is to capture factors behind professional views of indicator usefulness as a common structure for assessing healthcare performance and their important characteristics to design limited key performance indicators (PIs) for holistic hospital management. Design/methodology/approach - Two surveys were conducted using self-administered questionnaires, in which hospital manager/staff respondents were asked to rate the 52 PIs' usefulness. In total, 228 manager and 894 staff responses were collected. Findings - Eight factors were elicited from manager and staff responses as performance measures with 72 percent cumulative variance accounted for. Hospital managers and staff showed similar performance measure perceptions: high-utility acknowledgment on safety, operational efficiency and patient/employee satisfaction but relatively low-employee development concerns. Manager indicator usefulness perceptions were rather homogeneous and significantly higher than staff for almost all performance measures. Practical implications - Homogeneous manager views mean that a single key PI set for hospital management may be established regardless of hospital attributes. The following aspects may be measures that should be managed in a healthcare organization based on their key PIs: patient/employee safety, operational efficiency, financial effectiveness and patient/employee satisfaction. Originality/value - This is a pilot study on hospital management PIs in Japan. The eight-dimensional factor structure and findings about healthcare provider perceptions may be useful for healthcare management. PMID:27477935

Managing healthcare information: analyzing trust.
Söderström, Eva; Eriksson, Nomie; Åhlfeldt, Rose-Mharie
2016-08-01
Purpose - The purpose of this paper is to analyze two case studies with a trust matrix tool, to identify trust issues related to electronic health records. Design/methodology/approach - A qualitative research approach is applied using two case studies. The data analysis of these studies generated a problem list, which was mapped to a trust matrix. Findings - Results demonstrate flaws in current practices and point to achieving balance between organizational, person and technology trust perspectives. The analysis revealed three challenge areas, to: achieve higher trust in patient-focussed healthcare; improve communication between patients and healthcare professionals; and establish clear terminology. By taking trust into account, a more holistic perspective on healthcare can be achieved, where trust can be obtained and optimized. Research limitations/implications - A trust matrix is tested and shown to identify trust problems on different levels and relating to trusting beliefs. Future research should elaborate and more fully address issues within three identified challenge areas. Practical implications - The trust matrix's usefulness as a tool for organizations to analyze trust problems and issues is demonstrated. Originality/value - Healthcare trust issues are captured to a greater extent and from previously unchartered perspectives. PMID:27477934
Visualizing desirable patient healthcare experiences.
Liu, Sandra S; Kim, Hyung T; Chen, Jie; An, Lingling
2010-01-01
High healthcare cost has drawn much attention and healthcare service providers (HSPs) are expected to deliver high-quality and consistent care. Therefore, an intimate understanding of the most desirable experience from a patient's and/or family's perspective as well as effective mapping and communication of such findings should facilitate HSPs' efforts in attaining sustainable competitive advantage in an increasingly discerning environment. This study describes (a) the critical quality attributes (CQAs) of the experience desired by patients and (b) the application of two visualization tools that are relatively new to the healthcare sector, namely the "spider-web diagram" and "promotion and detraction matrix." The visualization tools are tested with primary data collected from telephone surveys of 1,800 patients who had received care during calendar year 2005 at 6 of 61 hospitals within St. Louis, Missouri-based, Ascension Health. Five CQAs were found by factor analysis. The spider-web diagram illustrates that communication and empowerment and compassionate and respectful care are the most important CQAs, and accordingly, the promotion and detraction matrix shows those attributes that have the greatest effect for creating promoters, preventing detractors, and improving consumer's likelihood to recommend the healthcare provider.

[Fostering LGBT-friendly healthcare services].
Wei, Han-Ting; Chen, Mu-Hong; Ku, Wen-Wei
2015-02-01
LGBT (lesbian, gay, bisexual, transgender) patients suffer from stigma and discrimination when seeking healthcare. A large LGBT healthcare survey revealed that 56% of gay patients and 70% of transgender patients suffered some type of discrimination while seeking healthcare in 2014. The fostering of LGBT-friendly healthcare services is not just an advanced step of gender mainstreaming but also a fulfillment of health equality and equity. Additionally, LGBT-friendly healthcare services are expected to provide new opportunities for healthcare workers. Therefore, proactive government policies, education, research, and clinical practice should all encourage the development of these healthcare services. We look forward to a well-developed LGBT-friendly healthcare system in Taiwan. PMID:25631181

Healthcare financing: how does Turkey compare?
Akhmedjonov, Alisher; Güç, Yunus; Akinci, Fevzi
2011-01-01
The authors provide an overview of Turkey's healthcare financing. After comparing financing data on Turkey and other Organization for Economic Cooperation and Development (OECD) member countries, they examine Turkey's performance on a wide range of healthcare input and outcome indicators using descriptive data drawn from the World Health Organization, World Bank, OECD, and Turkish Statistical Institute. The data analysis shows that Turkey ranks low by a number of key healthcare indicators across the OECD countries. Empirical analysis suggests that although many factors are associated with improvements in healthcare outcomes, a significant part of changes in life expectancy at birth are associated with higher spending on healthcare.

Targeted Learning in Healthcare Research.
Gruber, Susan
2015-12-01
The increasing availability of Big Data in healthcare encourages investigators to seek answers to big questions. However, nonparametric approaches to analyzing these data can suffer from the curse of dimensionality, and traditional parametric modeling does not necessarily scale. Targeted learning (TL) combines semiparametric methodology with advanced machine learning techniques to provide a sound foundation for extracting information from data. Predictive models, variable importance measures, and treatment benefits and risks can all be addressed within this framework. TL has been applied in a broad range of healthcare settings, including genomics, precision medicine, health policy, and drug safety. This article provides an introduction to the two main components of TL, targeted minimum loss-based estimation and super learning, and gives examples of applications in predictive modeling, variable importance ranking, and comparative effectiveness research.

Legitimate Allocation of Public Healthcare
Lippert-Rasmussen, Kasper; Lauridsen, Sigurd
2009-01-01
Citizens' consent to political decisions is often regarded as a necessary condition of political legitimacy. Consequently, legitimate allocation of healthcare has seemed almost unattainable in contemporary pluralistic societies. The problem is that citizens do not agree on any single principle...... governing priorities among groups of patients. The Accountability for Reasonableness (A4R) framework suggests an ingenious solution to this problem of moral disagreement. Rather than advocating any substantive distributive principle, its advocates propose a feasible set of conditions, which, if met by...

Assessing quality across healthcare subsystems in Mexico.
Puig, Andrea; Pagán, José A; Wong, Rebeca
2009-01-01
Recent healthcare reform efforts in Mexico have focused on the need to improve the efficiency and equity of a fragmented healthcare system. In light of these reform initiatives, there is a need to assess whether healthcare subsystems are effective at providing high-quality healthcare to all Mexicans. Nationally representative household survey data from the 2006 Encuesta Nacional de Salud y Nutrición (National Health and Nutrition Survey) were used to assess perceived healthcare quality across different subsystems. Using a sample of 7234 survey respondents, we found evidence of substantial heterogeneity in healthcare quality assessments across healthcare subsystems favoring private providers over social security institutions. These differences across subsystems remained even after adjusting for socioeconomic, demographic, and health factors. Our analysis suggests that improvements in efficiency and equity can be achieved by assessing the factors that contribute to heterogeneity in quality across subsystems. PMID:19305224
Patient Safety and Healthcare Quality
Aikaterini Toska
2012-01-01
Full Text Available Introduction: Due to a variety of circumstances and world-wide research findings, patient safety andquality care during hospitalization have emerged as major issues. Patient safety deficits may burdenhealth systems as well as allocated resources. The international community has examined severalproposals covering general and systemic aspects in order to improve patient safety; several long-termprograms and strategies have also been implemented promoting the participation of health-relatedagents, and also government agencies and non-governmental organizations.Aim: Those factors that have negative correlations with patient safety and quality healthcare weredetermined; WHO and EU programs as well as the Greek health policy were also reviewed.Method: Local and international literature was reviewed, including EU and WHO official publications,by using the appropriate keywords.Conclusions: International cooperation on patient safety is necessary in order to improvehospitalization and healthcare quality standards. Such incentives depend heavily on establishing worldwideviable and effective health programs and planning. These improvements also require further stepson safe work procedures, environment safety, hazard management, infection control, safe use ofequipment and medication, and sufficient healthcare staff.
Healthcare Workers and Workplace Violence
Tevfik Pinar
2013-06-01
Full Text Available Workplace violence is a threatening worldwide public health problem. Healthcare workers have under particular risk of workplace violence, and they are being exposed to violence 4-16 times more than other service workers. The frequency of violence in the health sector in the world has indicated in different range of results since there is no consistent definition of workplace violence and differences in research methodology (any type of violence: 22,0% - 60,0%; physical violence: 2,6% - 57,0%; verbal violence: 24,3% - 82,0%; sexual harassment: %1,9 - 10,5%. All healthcare workers have right to work in a safe working place. The safety of healthcare workers should deserve the same priority as patient safety. Various risk factors including social, cultural, environmental, organizational and personal elements play a role in the formation of workplace violence that is very important for our country. Considering all those factors, the workplace violence in health sector should be seriously handled and the strategies and policies must be developed for prevention.

Conflict resolution in healthcare management.
Lipcamon, James D; Mainwaring, Brian A
2004-01-01
Conflict causes decided tension in the workplace and often produces poor professional outcomes. A manager dealing with conflict can experience a crisis of confidence and often ends up second-guessing himself or herself, regardless of how a situation has been handled. In some organizations, conflict is not viewed positively or as an opportunity for improvement. In these organizations, most individuals will see conflict as being unproductive, unpleasant, and a waste of time and energy. Yet, conflict provides employees with critical feedback on how things are going. When viewed in a positive context, even personality conflicts may provide information to the healthcare manager about what is not working in the organization. If conflict is not directed and controlled, it can have damaging effects in the workplace, stifling the growth of departments and deflating employee morale. Our job as healthcare managers is to deal with conflict so that it does not decrease productivity or detract from the provision of patient-centered care. There are 4 general sources for interpersonal conflict: personal differences, informational deficiency, role incompatibility, and environmental stress. There are 5 common responses used in dealing with conflict: forcing, accommodating, avoiding, compromising, and collaborating. Healthcare managers should become comfortable with using all of these approaches. PMID:15259690
Workplace Bullying among Healthcare Workers
María José Montero-Simó
2013-07-01
Full Text Available This paper aims to assess consistent predictors through the use of a sample that includes different actors from the healthcare work force to identify certain key elements in a set of job-related organizational contexts. The utilized data were obtained from the 5th European Working Conditions Survey, conducted in 2010 by the European Foundation for the Improvement of Living and Working Conditions. In light of these objectives, we collected a subsample of 284 health professionals, some of them from the International Standard Classification of Occupations—subgroup 22—(ISCO-08. The results indicated that the chance of a healthcare worker referring to him/herself as bullied increases among those who work on a shift schedule, perform monotonous and rotating tasks, suffer from work stress, enjoy little satisfaction from their working conditions, and do not perceive opportunities for promotions in their organizations. The present work summarizes an array of outcomes and proposes within the usual course of events that workplace bullying could be reduced if job demands were limited and job resources were increased. The implications of these findings could assist human resource managers in facilitating, to some extent, good social relationships among healthcare workers.
Romanian healthcare system at a glance
Christiana Balan
2013-04-01
Full Text Available The Romanian healthcare system is facing constant challenges to produce high quality care with low costs. Objectives The paper aims to analyze the efficiency of the Romanian healthcare system in terms of resources allocation. The evaluation and the dimension of healthcare system efficiency are important for identifying a balance between the resources required and the health outcomes. Prior Work Previous studies describe the Romanian healthcare system as a system in transition. This study focuses on the relationship between the inputs and outputs of the system. Approach In order to assess the efficiency of the Romanian healthcare system we use Data Envelopment Analysis approach. Both input and output healthcare indicators are observed for the period 1999-2010 and the years when healthcare inputs have been used efficiently are identified. Results The results show that human, financial, and technological resources have been used at maximum capacity in 1999, 2003, 2004, 2007 and 2010. Implications Though efficiency is defined differently by diverse stakeholders, healthcare policies should focus on rising the responsibility of communities and individuals for better treatments and services and better access to information on healthcare providers. Value The paper is an empirically based study of the healthcare resources allocation in Romania.

Decision-making in healthcare as a complex adaptive system.
Kuziemsky, Craig
2016-01-01
Healthcare transformation requires a change in how the business of healthcare is done. Traditional decision-making approaches based on stable and predictable systems are inappropriate in healthcare because of the complex nature of healthcare delivery. This article reviews challenges to using traditional decision-making approaches in healthcare and how insight from Complex Adaptive Systems (CAS) could support healthcare management. The article also provides a system model to guide decision-making in healthcare as a CAS. PMID:26656389
Requirements for Interoperability in Healthcare Information Systems
Rita Noumeir
2012-01-01
Full Text Available Interoperability is a requirement for the successful deployment of Electronic Health Records (EHR. EHR improves the quality of healthcare by enabling access to all relevant information at the diagnostic decision moment, regardless of location. It is a system that results from the cooperation of several heterogeneous distributed subsystems that need to successfully exchange information relative to a specific healthcare process. This paper analyzes interoperability impediments in healthcare by first defining them and providing concrete healthcare examples, followed by discussion of how specifications can be defined and how verification can be conducted to eliminate those impediments and ensure interoperability in healthcare. This paper also analyzes how Integrating the Healthcare Enterprise (IHE has been successful in enabling interoperability, and identifies some neglected aspects that need attention.
Occupational Hazards in the Thai Healthcare Sector.
Tipayamongkholgul, Mathuros; Luksamijarulkul, Pipat; Mawn, Barbara; Kongtip, Pornpimol; Woskie, Susan
2016-05-01
Healthcare personnel work in vulnerable conditions that can adversely impact physical and/or mental health. This paper aims to synthesize the state of knowledge on work-related illnesses, injuries, and risks experienced by Thai healthcare workers. We found that Thai healthcare personnel, like others worldwide, are at risk for injury related to needle sticks and sharp instruments; infectious diseases due to biological hazards exposure such as airborne pathogens and patient secretions; muscle pain due to workload and long duration of work; and psychological disorders related to stressful working conditions. Because detailed surveillance data are limited for the Thai healthcare workforce, we recommend that additional surveillance data on Thai healthcare workers' health outcomes be collected. Future research efforts should also focus on evidence-based interventions in order to develop methods to prevent and treat occupational health injuries and illnesses acquired in the workplace for Thai healthcare sector workers.

The financing of healthcare in Ireland
Durkan, Joe
1994-01-01
It is an interesting aspect of the current debate with regard to healthcare in developed countries that the discussion starts with the finance of healthcare. What makes it interesting is that, with the exception of the US, healthcare is predominantly financed by government through a combination of a social welfare contribution and general taxation. There is some private financing through private insurance, but tax benefits for insurance and the universality attaching to most public systems ef...

Value-based procurement: Canada's healthcare imperative.
Prada, Gabriela
2016-07-01
Value-based healthcare models are being adopted globally to maximize value for patients. Given that procurement is at the heart of purchasing value, value-based procurement goes hand in hand with value-based healthcare. Shifting procurement's traditional focus on short-term cost savings to a more holistic objective that includes health system performance and patient outcomes, giving preference to longer-term cost efficiencies, and working with suppliers to identify opportunities to develop more innovative products and services, is proving successful in leading jurisdictions. This article presents an overview of value within healthcare systems and how healthcare value-based procurement is being implemented across various jurisdictions. PMID:27278137
Healthcare operations management through use of simulation
Mustafee, Navonil; Williams, Michael D
2012-01-01
Over the past decades healthcare organisations have grown in size and complexity and healthcare costs have outpaced economic growth. In countries where healthcare is publicly-funded, increasing costs have traditionally meant a rise in the healthcare budgets in real terms; however, the ongoing global financial and economic crisis (2007-present) has had spending implications on governmental budgets for public resources in several countries. This apparent contradiction - "provide better service at a lesser cost" - which may last for years to come therefore necessitates the careful use of the allo
Innovation in healthcare team feedback.
Plaza, Christine; Beard, Leslie; Fonzo, Anthony Di; Tommaso, Michael Di; Mujawaz, Yaman; Serra-Julia, Marcel; Morra, Dante
2011-01-01
Healthcare delivery is evolving from individual, autonomous practice to collaborative team practice. However, barriers such as professional autonomy, time constraints and the perception of error as failure preclude learning behaviours that can facilitate organizational learning and improvement. Although experimentation, engaging in questions and feedback, discussing errors and reflecting on results can facilitate learning and promote effective performance, the cultural barriers within healthcare can prevent or inhibit this type of behaviour among teams. At the University Health Network's Centre for Innovation in Complex Care, we realize the need for a tool that facilitates learning behaviour and is sensitive to the risk-averse nature of the clinical environment. The vehicle for the Team Feedback Tool is a web-based application called Rypple (www.rypple.com), which allows team members to provide anonymous, rapid-fire feedback on team processes and performance. Rypple facilitates communication, elicits feedback and provokes discussion. The process enables follow-up face-to-face team discussions and encourages teams to create actionable solutions for incremental changes to enhance team health and performance. The Team Feedback Tool was implemented and piloted in general internal medicine at the University Health Network's Toronto General Hospital from early May 2009 to July 2009 to address the issues of teamwork and learning behaviour in the clinical environment. This article explores the opportunities and barriers associated with the implementation of the Team Feedback Tool. PMID:21841396

Understanding bullying in healthcare organisations.
Allen, Belinda
2015-12-01
Bullying is a pervasive problem in healthcare organisations. Inquiries and reports on patient care and poor practice in the NHS have emphasised the substantial negative effects this behaviour may have on patient care. If bullying is to be addressed, it is crucial we develop clarity about what behaviours constitute bullying and how these behaviours differ from other negative behaviours in the workplace. It is important that we recognise the extent of the problem; statistics on the prevalence of bullying are likely to be an underestimate because of under-reporting of bullying. Effective interventions may only be designed and implemented if there is knowledge about what precipitates bullying and the magnitude of the changes required in organisations to tackle bullying. Individuals should also be aware of the options that are available to them should they be the target of bullying behaviour and what they should do if they witness bullying in their workplace.

This paper will focus on health care technologies and initiatives, particularly, Electronic Health Records (EHRs). These technologies are ascribed various potentialities, attributing them the capacity to do a wide range of things, from improving efficiency to saving medical costs and even saving...... lives. These complex and often conflicting imagined potentialities lead to inflicted burden on designers, policy makers and healthcare practitioners who are faced with different realities on the ground. The conflicting notions have real life effects as these impact our present understanding of, and...... actions taken toward, these technologies. To better understand the material and discursive processes that are at play in shaping our present and future understanding of EHR technologies, the paper offers the analytical notion of imagined potentialities, whereby a technology is imagined to possess an...
