Patients' subjective experience of nurse-led clinics : a qualitative systematic review
Creators: name: Jakimowicz, S
Publisher: name: University Of Tasmania
Year: 2023

description: Aim To determine factors that impact the subjective experience of patients attending nurse-led clinics. Background As the number of nurse-led clinics increases in response to health system needs, evaluation has focused on clinical outcomes and cost. The experience of the patient has been less researched despite person-centred care being central to the health care political agenda for many years. Assessing patient experiences provides information of factors that impact the health care encounter that can inform policy and practice development. Design A systematic review of primary, qualitative literature was conducted using the methodology of meta-aggregation proposed by The Joanna Briggs Institute (JBI). Data Sources Published work from 1990 to the present date in English was located using databases CINAHL, PubMed, Medline and PsycINFO. Reference lists of all significant papers were searched and analysed. Review Methods Two reviewers assessed the retrieved papers for methodological quality using the System for the Unified Management, Assessment and Review of Information (JBI-SUMARI) software package. Results were synthesised using the metaaggregation method. The Qualitative Assessment Review Instrument (JBI-QARI) was utilized to critically appraise, extract data and aggregate findings in a rigorous and unbiased method. Results Eleven retrieved studies met all inclusion criteria and were incorporated in the review process. The papers described varied qualitative approaches: phenomenological-hermeneutic (6), exploratory or descriptive (3), and grounded theory (2). Nine categories were drawn from 46 key findings. Further analysis produced three synthesis statements titled: (i) establishment of a therapeutic relationship, (ii) effective communication, and (iii) clinical skills and collaboration. Conclusion Factors that influence patient experiences of nurse-led clinics should be addressed if such clinics are to continue to play a major role in the health care system. In order to improve patient experience of nurse-led clinics, nurses need to 'go back to basics' with regard to holistic nursing care. The concepts of the person-centred care model are key factors impacting patients' subjective experience of nurse-led health care. Further qualitative research is required to evaluate the person-centred care model in relation to clinical outcomes, clinical practice and educational programs for nursing students, novice and advanced practice nurses.
Building information modeling – A game changer for interoperability and a chance for digital preservation of architectural data?

description: Digital data associated with the architectural design-andconstruction process is an essential resource alongside -and even past- the lifecycle of the construction object it describes. Despite this, digital architectural data remains to be largely neglected in digital preservation research – and vice versa, digital preservation is so far neglected in the design-and-construction process. In the last 5 years, Building Information Modeling (BIM) has seen a growing adoption in the architecture and construction domains, marking a large step towards much needed interoperability. The open standard IFC (Industry Foundation Classes) is one way in which data is exchanged in BIM processes. This paper presents a first digital preservation based look at BIM processes, highlighting the history and adoption of the methods as well as the open file format standard IFC (Industry Foundation Classes) as one way to store and preserve BIM data.

description: I critically review recent lattice QCD results relevant for kaon phenomenology, as well as the methods that are used to obtain them. The focus is on calculations with N_f=2 and N_f=2+1 flavors of sea quarks. Concerning methodology, the subjects covered include a discussion of how best to extrapolate and/or interpolate results to the physical quark-mass point, a scheme for assessing the extent to which a lattice QCD calculation includes the various effects required to compute a given quantity reliably and a procedure for averaging lattice results. The phenomenological topics that I review comprise leptonic and semileptonic kaon decays, as well as neutral kaon mixing and CP violation in K->ππdecays.

Inner equivalence of thick subalgebras
Creators: name: Kerr, Charles R.
Publisher: name: University of British Columbia
Year: 2011

description: In this thesis we construct some examples of thick subalgebras ɛ of factors ɑ. ɛ is thick in ɑ if (ɛ' ∩ ɑ) is maximal abelian in ɑ. We are concerned with their inner equivalence: given the thick subalgebras ɛ and ℱ in ɑ, does there exist a unitary U є ɑ such that U є U* = ℱ ? Examples of thick subalgebras which are not maximal abelian have been given by Dixmier and Kadison. Later Bures constructed numerous examples which he distinguished by use of certain invariants. We use Bures's construction to get, in certain factors ɑ of types II₁,- II₀₀, III, uncountable families {ɛ[subscript i]: iєℱ} of thick subalgebras of ɑ such that ɛ[subscript i] is not inner equivalent to ɛ[subscript J] when i ≠ J (We are able to add one example to those constructed by Bures). In each family, the ɛ[subscript i]cannot be distinguished by means of Bures's invariants, and so we are forced to show their non-inner-equivalence by direct calculations.
The effect of crisis resource management training on error in the emergency department : a systematic review
Creators: name: Jakimowicz, MD
Publisher: name: University Of Tasmania
Year: 2023

description: Background Emergency department clinicians confront problems that are often ill defined, rapidly evolving and have severe consequences. The propensity for error is, therefore, significant. Crisis Resource Management training has gained recent attention as a means of improving teamwork and reducing error in the emergency department. Methods A systematic review of the literature was conducted to determine the effectiveness of Crisis Resource Management training in reducing error in the emergency department. The following databases were searched: CINAHL, EMBASE, MEDLINE, PsycINFO, PubMed Central and Google Scholar. Published and unpublished, experimental and quasi-experimental studies were considered. Relevant studies were appraised using the Joanna Briggs Institute Meta Analysis Statistics Assessment and Review Instrument. Results The literature search yielded a total of 491 published studies. After screening and critical appraisal, two studies were included. The first, a quasi-experimental before and after study, reported an 18 percent decrease in patient safety events following the intervention, which was not significant (p=0.22). The second, a quasiexperimental, non-randomised control, before and after study, reported an 85 percent decrease in observed errors following the intervention. When compared to the control group, however, this was not significant (p=0.140). Due to the number and heterogeneity of the included studies, the results were combined into a narrative synthesis rather than a meta-analysis. The review suffered from publication bias because no unpublished studies were located. Conclusion There is limited evidence that Crisis Resource Management training reduces error in the emergency department. Further research, utilising an experimental or mixed methods design should be carried out to measure the overall effectiveness of Crisis Resource Management training within the emergency department.
Bowen's equation in the non-uniform setting

description: We show that Bowen's equation, which characterises the Hausdorff dimension of certain sets in terms of the topological pressure of an expanding conformal map, applies in greater generality than has been heretofore established. In particular, we consider an arbitrary subset Z of a compact metric space and require only that the lower Lyapunov exponents be positive on Z, together with a tempered contraction condition. Among other things, this allows us to compute the dimension spectrum for Lyapunov exponents for maps with parabolic periodic points, and to relate the Hausdorff dimension to the topological entropy for arbitrary subsets of symbolic space with the appropriate metric.

The ties that bind - On the impact of losing a consortium member in a cooperatively operated digital preservation system

description: Cooperatively operated digital preservation systems offer institutions of varying size the chance to actively participate in digital preservation. In current times of budget cuts they are also a valuable asset to larger memory institutions. While the benefits of cooperatively operated systems have been discussed before, the risks associated with a consortial solution have not been analyzed in detail. TIB hosts the Goportis Digital Archive which is used by two large national subject libraries as well as by TIB itself. As the host of this comparatively small preservation network, TIB has started to analyze the particular risk which losing a consortium member poses to the overall system operation. This paper presents the current status of this work-in-progress and highlights two areas: risk factors associated with cost and risk factors associated with the content. While the paper is strictly written from the viewpoint of the consortial leader/ host of this specific network, the underlying processes shall be beneficial to other cooperatively operated digital preservation systems.

description: The stochastic background of gravitational wave signals arising from the core-collapse supernovae is produced through various complex mechanisms that need detailed and careful investigation. We proposed a simplified multi-peak waveform of the amplitude spectrum. The corresponding energy spectra of our model fit the energy spectra obtained from different numerical simulations of various types of core-collapse events such as non-rotating, slow and fast rotating massive progenitors resulting in neutron stars. The maximum dimensionless energy density $Ω_{gw}$ corresponding to our model is of $\mathcal{O}(10 {^{-12})} $ around 650 Hz. Assuming some degree of uncertainty, we estimated the parameters for the core collapse waveform using BILBY. We studied the detectability of the signal of our model against gravitational-wave detectors like the Einstein Telescope, advanced LIGO and Virgo. Our study indicates that these detectors have to gain more sensitivity to pick up the gravitational wave signals of stochastic background.

description: Quantum critical points are characterized by scale invariant correlations and correspondingly long ranged entanglement. As such, they present fascinating examples of quantum states of matter, the study of which has been an important theme in modern physics. Nevertheless very little is known about the fate of quantum criticality under non equilibrium conditions. In this paper we investigate the effect of external noise sources on quantum critical points. It is natural to expect that noise will have a similar effect to finite temperature, destroying the subtle correlations underlying the quantum critical behavior. Surprisingly we find that in many interesting situations the ubiquitous 1/f noise preserves the critical correlations. The emergent states show intriguing interplay of intrinsic quantum critical and external noise driven fluctuations. We demonstrate this general phenomenon with specific examples in solid state and ultracold atomic systems. Moreover our approach shows that genuine quantum phase transitions can exist even under non equilibrium conditions.

description: We report on soliton-fission mediated infrared supercontinuum generation in liquid-core step-index fibers using highly transparent carbon chlorides (CCl4, C2Cl4). By developing models for the refractive index dispersions and nonlinear response functions, dispersion engineering and pumping with an ultrafast thulium fiber laser (300 fs) at 1.92 μm, distinct soliton fission and dispersive wave generation was observed, particularly in the case of tetrachloroethylene (C2Cl4). The measured results match simulations of both the generalized and a hybrid nonlinear Schrödinger equation, with the latter resembling the characteristics of non-instantaneous medium via a static potential term and representing a simulation tool with substantially reduced complexity. We show that C2Cl4 has the potential for observing non-instantaneous soliton dynamics along meters of liquid-core fiber opening a feasible route for directly observing hybrid soliton dynamics.

description: The Leibniz-Institute of Atmospheric Physics (IAP) in Kühlungsborn started to install a new MST radar on the North-Norwegian island Andøya (69.30° N, 16.04° E) in 2009. The new Middle Atmosphere Alomar Radar System (MAARSY) replaces the previous ALWIN radar which has been successfully operated for more than 10 years. The MAARSY radar provides increased temporal and spatial resolution combined with a flexible sequential point-to-point steering of the radar beam. To increase the spatiotemporal resolution of the observations a 16-port Butler matrix has been built and implemented to the radar. In conjunction with 64 Yagi antennas of the former ALWIN antenna array the Butler matrix simultaneously provides 16 individual beams. The beam forming capability of the Butler matrix arrangement has been verified observing the galactic cosmic radio noise of the supernova remnant Cassiopeia A. Furthermore, this multi beam configuration has been used in passive experiments to estimate the cosmic noise absorption at 53.5 MHz during events of enhanced solar and geomagnetic activity as indicators for enhanced ionization at altitudes below 90 km. These observations are well correlated with simultaneous observations of corresponding beams of the co-located imaging riometer AIRIS (69.14° N, 16.02° E) at 38.2 MHz. In addition, enhanced cosmic noise absorption goes along with enhanced electron densities at altitudes below about 90 km as observed with the co-located Saura MF radar using differential absorption and differential phase measurements.

description: We analyze the temporal variation of the diurnal anisotropy of sub-TeV cosmic ray intensity observed with the Matsushiro (Japan) underground muon detector over two full solar activity cycles in 1985-2008. The average sidereal amplitude over the entire period is 0.034+-0.003 %, which is roughly one third of the amplitude reported from AS and deep-underground muon experiments monitoring multi-TeV GCR intensity suggesting a significant attenuation of the anisotropy due to the solar modulation. We find, on the other hand, only weak correlations either with the solar activity- or magnetic-cycles. We examine the temporal variation of the "single-band valley depth" (SBVD) quoted by the Milagro experiment and, by contrast with recent Milagro reports, we find no steady increase in the Matsushiro observations in a 7-year period between 2000 and 2007. We suggest, therefore, that the steady increase of the SBVD reported by the Milagro experiment is not caused by the decreasing solar modulation in the declining phase of the 23rd solar activity cycle.

description: We investigate the dynamics of microcapsules in linear shear flow within a reduced model with two degrees of freedom. In previous work for steady shear flow, the dynamic phases of this model, i.e. swinging, tumbling and intermittent behaviour, have been identified using numerical methods. In this paper, we integrate the equations of motion in the quasi-spherical limit analytically for time-constant and time-dependent shear flow using matched asymptotic expansions. Using this method, we find analytical expressions for the mean tumbling rate in general time-dependent shear flow. The capsule dynamics is studied in more detail when the inverse shear rate is harmonically modulated around a constant mean value for which a dynamic phase diagram is constructed. By a judicious choice of both modulation frequency and phase, tumbling motion can be induced even if the mean shear rate corresponds to the swinging regime. We derive expressions for the amplitude and width of the resonance peaks as a function of the modulation frequency.

A sculptural re-interpretation of aspects of European two dimensional visual art in the period 1910-1940
Creators: name: Fisher, R
Publisher: name: University Of Tasmania
Year: 2023

description: This project investigates the apparent dichotomy between solid sculptural forms and their visual apprehension, focussing on the relationship of object to pictorial plane. The writings of Paul Klee and Wassily Kandinsky provide a background and a particular insight into what Klee calls '...the kinetic energies which move the point into a line, the line into a plane and the plane into a spatial dimension.' (Notebooks, Volume 1: The Thinking Eye) This project adds solid sculptural form - volume - to Klee's sequence by elevating the point from a flat two-dimensional plane to the three-dimensional space of Euclidean geometry. Three key research outcomes were: ‚Äö A methodology using computer aided drawing (CAD) software, a numerically controlled routing machine, step by step photographic documentation and computer animation was developed in the course of the project. ‚Äö A concept change involving the replacement of the rigours of the grid with a process using the intersection of the horizon and gravity as drawing coordinates was introduced. ‚Äö A method of planar layer construction of solid objects was developed to heighten perception of the pictorial qualities of the object. The research project has been manifested in a substantial body of sculptures, maquettes, and CAD drawings.

description: We study the impact of the diagonal frustrating couplings on the quantum phase diagram of a two-leg ladder composed of alternating spin-1 and spin-1/2 rungs. As the coupling strength is increased the system successively exhibits two gapped paramagnetic phases (a rung-singlet and a Haldane-like non-degenerate states) and two ferrimagnetic phases with different ferromagnetic moments per rung. The first two states are similar to the phases studied in the frustrated spin-1/2 ladder, whereas the magnetic phases appear as a result of the mixed-spin structure of the model. A detailed characterization of these phases is presented using density-matrix renormalization-group calculations, exact diagonalizations of periodic clusters, and an effective Hamiltonian approach inspired by the analysis of numerical data. The present theoretical study was motivated by the recent synthesis of the quasi-one-dimensional ferrimagnetic material Fe$^{II}$Fe$^{III}$ (trans-1,4-cyclohexanedicarboxylate) exhibiting a similar ladder structure.

description: Silk continues to amaze: over the past decade, new research threads have emerged that include the use of silk fibroin for advanced pharmaceutics, including its suitability for drug delivery. Despite this ongoing interest, the details of silk fibroin structures and their subsequent drug interactions at the molecular level remain elusive, primarily because of the difficulties encountered in modeling the silk fibroin molecule. Here, we generated an atomistic silk model containing amorphous and crystalline regions. We then exploited advanced well-tempered metadynamics simulations to generate molecular conformations that we subsequently exposed to classical molecular dynamics simulations to monitor both drug binding and release. Overall, this study demonstrated the importance of the silk fibroin primary sequence, electrostatic interactions, hydrogen bonding, and higher-order conformation in the processes of drug binding and release. © Copyright © 2019 American Chemical Society.
Homogeneity of combinatorial spheres
Creators: name: Walker, Alexander Crawford
Publisher: name: University of British Columbia
Year: 2011

description: The object of this thesis is to cover the results of [1] from a piecewise linear point of view. The principal result of [1] is the theorem on the homogeneity of spheres, i.e. the complement of a combinatorial n-cell in a combinatorial n-sphere is a combinatorial n-cell. A piecewise linear proof of this theorem by a "long induction" using regular neighbourhoods and collapsing was given in [4]. A direct piecewise linear proof appeared recently in [2]; it is based on the existence of a "collar" for the boundary of a combinatorial manifold with boundary. Our proof is similar to the proof in [2]. We proceed by induction on dimensions, proving simultaneously the existence of a collar for the boundary of a combinatorial manifold with boundary and the homogeneity theorem. From [2] we adopted an argument which eliminates a certain combinatorial technique applied in [1] and involving induction on the length of stellar subdivisions. The results of [1] were previously interpreted in piecewise linear topology by use of a theorem in [3] stating that piecewise linearly homeomorphic simplicial complexes have subdivisions which are combinatorially equivalent in the sense of [1]. The thesis is divided into three parts. The first gives definitions and basic properties relating to simplicial complexes. The second concerns combinatorial manifolds, and in the third we present our proof of the piecewise linear homogeneity of spheres.

description: The intrinsic advantages of metallic Zn, like high theoretical capacity (820 mAh g−1), high abundance, low toxicity, and high safety have driven the recent booming development of rechargeable Zn batteries. However, the lack of high-voltage electrolyte and cathode materials restricts the cell voltage mostly to below 2 V. Moreover, dendrite formation and the poor rechargeability of the Zn anode hinder the long-term operation of Zn batteries. Here a high-voltage and durable Zn–graphite battery, which is enabled by a LiPF6-containing hybrid electrolyte, is reported. The presence of LiPF6 efficiently suppresses the anodic oxidation of Zn electrolyte and leads to a super-wide electrochemical stability window of 4 V (vs Zn/Zn2+). Both dendrite-free Zn plating/stripping and reversible dual-anion intercalation into the graphite cathode are realized in the hybrid electrolyte. The resultant Zn–graphite battery performs stably at a high voltage of 2.8 V with a record midpoint discharge voltage of 2.2 V. After 2000 cycles at a high charge–discharge rate, high capacity retention of 97.5% is achieved with ≈100% Coulombic efficiency. © 2019 The Authors. Published by WILEY-VCH Verlag GmbH & Co.

description: The metabolism and hypoxia tolerance of marine ectotherms play key roles in limiting species geographical ranges, but underlying traits have only been directly measured for a small fraction of biodiversity. Here we diagnose and analyse spatial and phylogenetic patterns in hypoxia tolerance and its temperature sensitivity at ecologically active metabolic rates, by combining a model of organismal oxygen (O2) balance with global climate and biogeographic data for approximately 25 000 animal species from 13 phyla. Large-scale spatial trait patterns reveal that active hypoxia tolerance is greater and less temperature sensitive among tropical species compared to polar ones, consistent with sparse experimental data. Species energetic demands for activity vary less with temperature than resting costs, an inference confirmed by available rate measurements. Across the tree of life, closely related species share similar hypoxia traits, indicating that evolutionary history shapes physiological tolerances to O2 and temperature. Trait frequencies are highly conserved across phyla, suggesting the breadth of global aerobic conditions selects for convergent trait diversity. Our results support aerobic limitation as a constraint on marine habitat distributions and their responses to climate change and highlight the under-sampling of aerobic traits among species living in the ocean's tropical and polar oxythermal extremes.This article is part of the theme issue ‘Evolutionary significance of variation in metabolic rates’.

Printmaking and the language of violence
Creators: name: Rees-Pagh, YD
Publisher: name: University Of Tasmania
Year: 2023

description: The aim of the project is to demonstrate that the traditional processes of printmaking, in particular etching, are relevant as a medium for artistic engagement with the subject of violence. My research investigates how printmaking has developed its own unique visual language as a means of addressing violence in our society, and specifically how artists have depicted violence using the medium of printmaking. To provide a context for my own practice, I examine artists from the past such as Jacques Callot, Francisco Goya, K‚àö¬ßthe Kollwitz, Otto Dix and Pablo Picasso, all of whom engaged with the medium of etching to convey violence, as well as the work of contemporary artists Leon Golub, Nancy Spero, William Kentridge, Diane Victor, Sandow Birk, and Jake and Dinos Chapman which addresses issues such as war, social unrest and abuse of political power. The tradition of socio-political printmaking in Australia is also briefly examined, revealing a relative lack of contemporary artists in this field dealing with the theme of violence. This research informed the directions for my own work. My own work began by addressing global violence issues. Experimentation with unconventional materials and processes formed an integral part of the journey. The resultant effects from this experimentation were layered into and became part of the work. The focus of my final work is on social violence in Australia, in particular the Cronulla riots of 2005. Thousands of people were involved in these riots, making them the largest racially motivated riots in Australian history. The major work, The Cronulla Riot, is a large etching completely covering the gallery wall. My intention is to emphasise the chaos of the riot, imparted through the layers of figurative imagery, imbuing a sense of time. The scale of the work enables the viewer to feel immersed in the violence. The work challenges traditional printmaking boundaries by virtue of scale, methodology and subject matter. The power of etching, using a painstaking autographic process, has given new life to the theme of violence; an issue not explored in the medium in relation to the Cronulla riots by any other contemporary Australian artist. The core technology of etching may be ancient, but it continues to present the contemporary artist with a powerful and dynamic medium for personal artistic expression.

Here we diagnose and analyze spatial and phylogenetic patterns in hypoxia tolerance and its temperature sensitivity at ecologically active metabolic rates, by combining a model of organismal O2 balance with global climate and biogeographic data for approximately 25k animal species from 13 phyla. Large-scale spatial trait patterns reveal that active hypoxia tolerance is greater and less temperature sensitive among tropical species compared to polar ones, consistent with sparse experimental data.

Is the Luttinger liquid a new state of matter?

description: We are demonstrating that the Luttinger model with short range interaction can be treated as a type of Fermi liquid. In line with the main dogma of Landau's theory one can define a fermion excitation renormalized by interaction and show that in terms of these fermions any excited state of the system is described by free particles. The fermions are a mixture of renormalized right and left electrons. The electric charge and chirality of the Landau quasi-particle is discussed.

Low-energy collisions of NH3 and ND3 with ultracold Rb atoms

description: We carry out quantum inelastic scattering calculations of collisions of Rb atoms with inverting NH3 and ND3 molecules in the energy range between 0 and 100 cm-1, which are important for experiments using velocity-controlled molecular beams to probe scattering resonances. We focus on molecules initially in the upper level of the ammonia inversion doublet, which are low-field-seeking and can be controlled in a Stark decelerator. We calculate the integral elastic and state-to-state inelastic cross sections in the coupled states approximation. We demonstrate the presence of both shape and Feshbach resonances in the elastic and inelastic cross sections at low collision energies and discuss their origin in terms of the bound states of Rb--ND3 complex. We also consider elastic and inelastic cross sections in the ultracold regime, using close-coupling calculations, in order to assess the viability of sympathetic cooling of ND3 by Rb. The inelastic cross section for relaxation to the lower level of the inversion doublet is smaller than expected for such a strongly coupled system, but is still likely to be too large to allow sympathetic cooling for ND3 in low-field-seeking states. However, there is a good prospect that sympathetic cooling will be possible for molecules in high-field-seeking states, even when the collision partner is a magnetically trapped atom in a low-field-seeking state.

description: Polymer semiconductors (PSCs) are an essential component of organic field-effect transistors (OFETs), but their potential for stretchable electronics is limited by their brittleness and failure susceptibility upon strain. Herein, a covalent connection of two state-of-the-art polymers—semiconducting poly-diketo-pyrrolopyrrole-thienothiophene (PDPP-TT) and elastomeric poly(dimethylsiloxane) (PDMS)—in a single triblock copolymer (TBC) chain is reported, which enables high charge carrier mobility and low modulus in one system. Three TBCs containing up to 65 wt% PDMS were obtained, and the TBC with 65 wt% PDMS content exhibits mobilities up to 0.1 cm2 V−1 s−1, in the range of the fully conjugated reference polymer PDPP-TT (0.7 cm2 V−1 s−1). The TBC is ultrasoft with a low elastic modulus (5 MPa) in the range of mammalian tissue. The TBC exhibits an excellent stretchability and extraordinary durability, fully maintaining the initial electric conductivity in a doped state after 1500 cycles to 50% strain. © 2020 The Authors.

Existence of algebras of symmetry-classes of tensors with respect to translation-in-variant pairs

description: The notion of the 'classical' multilinear maps such as the symmetric and skew-symmetric maps, has the following generalization: given a vector-space V and a pair (H[subscript n],X[subscript n]) where is a subgroup of the symmetric group S[subscript n] and X[subscript n] is a character of H[subscript n], we consider multilinear maps from V[superscript n] (n-fold cartesian product of V ) into any other vector space, which are ‘symmetric with respect to (H[subscript n],X[subscript n])’, i.e., which have a certain symmetry in their values on permuted tuples of vectors, where the permutations are in H[subscript n]. Given a pair (H[subscript n],X[subscript n]) and a vector-space V , we can construct a space V[superscript (n)] over V through which the maps 'symmetric with respect to (H[subscript n],X[subscript n])’ linearize. The space V[superscript (n)] is usually defined abstractly by means of a certain universal mapping property and gives the tensor, symmetric and Grassmarm spaces for the 'classical' maps. Given a sequence of pairs [formula omitted]and the corresponding spaces V[superscript (n)], we let [formula omitted] (where V[superscript b]) is the ground field). In the classical cases, A has a natural multiplicative operation which makes A an algebra, i.e., the Tensor, Symmetric and Grassmann algebras. This presentation has been motivated by the attempt to generalize the construction of an algebra A to a wider family of 'admissible' sequences of pairs [formula omitted]. This consideration has led us to investigate permutation groups on the numbers 1,2,3,… which are closed under a certain 'shift' of the permutations, i.e., if [formula omitted] is a permutation, we define [formula omitted] and we call a permutation group H 'translation-invariant' if for every [formula omitted] is also in H . We begin our presentation by characterising the 'translation-invariant' groups. We show that the study of these (infinite) groups can be reduced to the study of certain finite groups. Then, we proceed to discuss the lattice of the translation-invariant groups. Finally, we show that a translation-invariant group H , together, with an appropriate character X of H , represents an equivalence class of 'admissible' sequences of pairs [formula omitted]. For a particular choice of representatives of the equivalence class, we can construct an algebra of 'symmetry classes of tensors' which generalizes the Tensor, Symmetric and Grassmann algebras.
