A greener alternative? deliberative democracy meets local government in Australia
Creators: name: Zwart, IC
Publisher: name: University Of Tasmania
Year: 2023

description: In recent decades a search has been conducted among democratic theorists to find a decision making form that is both democratic, and able to produce outcomes that may be seen to favour the life supporting capacity of our natural systems. One form of decision making that has gained considerable interest from green theorists is participatory or deliberative democracy. It is suggested that compared to liberal representative structures, a deliberative conception of politics will allow for a more informed policy process that enables the discovery and support of generalisable rather than particular interests. As a consequence, citizen deliberation will produce outcomes that support the pre-eminence of the natural environment, while providing greater legitimacy and compliance with the agreements reached. These assumptions about the environmental credentials of deliberative forums are not entirely theoretical. In recent decades there has been a gradual movement within local government in Australia towards the use of participatory or deliberative models to support its existing representative structure. In particular, this has been driven by the emerging role of local government in addressing environmental issues. It is shown that despite questions regarding their reliability, many of the assumptions made within the deliberative democratic literature also exist within local processes to deliver favourable environmental outcomes. The thesis therefore tests the purported benefits of deliberative structures. It finds that citizen deliberation can produce more informed policy processes. However, the notion that deliberative structures will produce both environmentally favourable and universally legitimate outcomes is dependent upon a range of contextual factors. To support this thesis, existing research on public deliberation and two case studies in Australian local government are presented and examined. The first case study inspects the use of a precinct system at the Glenorchy City Council to address issues including waste management, while the second concerns the use of a citizens jury to address stormwater issues at the Waverley Municipal Council. Although a range of factors prove to have significant impacts upon the environmental outcomes that were achieved, the thesis concludes that the deliberative model can facilitate the greening of decision making, and enable a collective realisation of the benefits of active citizenship.

The qPlus sensor, a powerful core for the atomic force microscope

Subjects: subject: 530 Physik

description: Atomic force microscopy (AFM) was introduced in 1986 and has since made its way into surface science, nanoscience, chemistry, biology, and material science as an imaging and manipulating tool with a rising number of applications. AFM can be employed in ambient and liquid environments as well as in vacuum and at low and ultralow temperatures. The technique is an offspring of scanning tunneling microscopy (STM), where the tunneling tip of the STM is replaced by using a force sensor with an attached tip. Measuring the tiny chemical forces that act between the tip and the sample is more difficult than measuring the tunneling current in STM. Therefore, even 30 years after the introduction of AFM, progress in instrumentation is substantial. Here, we focus on the core of the AFM, the force sensor with its tip and detection mechanism. Initially, force sensors were mainly micro-machined silicon cantilevers, mainly using optical methods to detect their deflection. The qPlus sensor, originally based on a quartz tuning fork and now custom built from quartz, is self-sensing by utilizing the piezoelectricity of quartz. The qPlus sensor allows us to perform STM and AFM in parallel, and the spatial resolution of its AFM channel has reached the subatomic level, exceeding the resolution of STM. Frequency modulation AFM (FM-AFM), where the frequency of an oscillating cantilever is altered by the gradient of the force that acts between the tip and the sample, has emerged over the years as the method that provides atomic and subatomic spatial resolution as well as force spectroscopy with sub-piconewton sensitivity. FM-AFM is precise; because of all physical observables, time and frequency can be measured by far with the greatest accuracy. By design, FM-AFM clearly separates conservative and dissipative interactions where conservative forces induce a frequency shift and dissipative interactions alter the power needed to maintain a constant oscillation amplitude of the cantilever. As it operates in a noncontact mode, it enables simultaneous AFM and STM measurements. The frequency stability of quartz and the small oscillation amplitudes that are possible with stiff quartz sensors optimize the signal to noise ratio. Here, we discuss the operating principles, the assembly of qPlus sensors, amplifiers, limiting factors, and applications. Applications encompass unprecedented subatomic spatial resolution, the measurement of forces that act in atomic manipulation, imaging and spectroscopy of spin-dependent forces, and atomic resolution of organic molecules, graphite, graphene, and oxides.

description: We study the existence of realistic heterotic vacua on a new Abelian surface fibered Calabi-Yau threefold X with Z_8 x Z_8 fundamental group. Our main result is a no-go theorem, which says that (under mild assumptions) there is no stable holomorphic vector bundle on X satisfying the constraints required by global consistency of the heterotic vacuum and phenomenology. To prove the theorem we explore in some detail the Fourier-Mukai transform of vector bundles on Abelian surface fibrations.

Review of colloids in ore genesis
Creators: name: Large, RR
Publisher: name: University Of Tasmania
Year: 2023

description: Advances in the theory of colloidal chemistry over the past decade indicate that this state of matter may take part in ore forming processes to a far greater extent than is at present generally recognised. The stability of a colloidal sol system is subject to temperature, pressure, pH, ions in solution, and other colloidal species present. Most sulphide sols are stabilized in the presence of hydrogen sulphide, even to such an extent that NaCl and KCl may not cause coagulation. Silica sol probably has a very important stabilizing effect on most metal hydrosols. In many sol systems the pH of the solution determines the charge on individual particles end thus the degree of dispersion, The effect of temperature on sol stability is unknown but recent work tends to suggest that in some cases increased temperature results in decreased stability. Colloform (globular, framboidal, oolitic, reniform and botryoidal) textures have been successfully produced in the laboratory from sulphide gels. Such textures may also develop due to crystallization from true solutions, but structural criteria exist to differentiate the two origins. Ore textures exhibiting a crystalline form do not necessarily indicate precipitation from true solutions as crystalline textures may equally develop due to ageing of gels. There is no inter-dependence between the transport of metals as colloidal sols and their deposition as colloidal gels, Fluid inclusions present in minerals precipitated via the gel stage, may give little information on the composition of the ore fluid, or the temperature of precipitation.

description: The stability of homogeneous catalytic systems is an industrially crucial topic, which, however, receives comparatively little attention from academic research. Phosphites are among the most frequently used ligands in industrial, rhodium-catalyzed n-regioselective hydroformylation. However, they are particularly vulnerable to hydrolysis. Since the decomposition of ligands should be dependent on the substitution patterns, phenyl, tert-butyl and condensed ring systems of benzopinacolphosphites were evaluated concerning their activity, regioselectivity and hydrolysis stability. A series of twelve strongly related phosphites were synthesized, tested in the hydroformylation of isomeric n-octenes, and studied in hydrolysis experiments using in situ NMR spectroscopy. Our results show that substituents in the ortho-position, especially tert-butyl substituents, enhance hydrolysis stability while maintaining compelling activity and regioselectivity. In contrast, substituents in the para-position may destabilize the phosphite. © 2019 by the authors. Licensee MDPI, Basel, Switzerland.

Special emphasis is given on the analysis of the so-called anomalous (negative energy) mode of the Bogoliubov spectrum. We use analytical and numerical techniques to illustrate the connection of the anomalous mode to the precession dynamics of the vortex in the trap. Effects due to inhomogeneous interatomic interactions and dissipative perturbations motivated by finite temperature considerations are explored. We find that both of these effects may give rise to oscillatory instabilities of the vortex, which are suitably diagnosed through the perturbation-induced evolution of the anomalous mode, and being monitored by direct numerical simulations.

Port administration structures : (a study relating the characteristics of proficiency and autonomy in ports)
Creators: name: McMullan, Wallace Edward
Publisher: name: University of British Columbia
Year: 2011

description: This thesis is concerned with the various structures under which ports are administered. It is a curious fact that there are a great number of different types of port administration structures through which the major seaports of the world are administered. One important question out of which this thesis grew is: Given the variety of port administrative structures, what can be said in defense or in favor of each of these various forms of administration? This thesis reviews the goals of port activities and the methodology of port operations. Subsequently, the opinions of writers in the field are summarized and outlined. The results of a study of a series of reports by the International Bank for Reconstruction and Development (sections concerning port operations) are then reported. Finally, the thesis outlines the findings of a field study involving the Port of Vancouver, British Columbia, and the Port of Seattle, Washington, U.S.A. A thesis on such a general subject as Port Administration Structure may, at first, seem too broad and too nebulous for objective study. The necessity of subjecting the present structure of ports' administrative systems in Canada to objective analysis, is reason enough for a government white paper, which is presently in the making at National Harbours Board headquarters in Ottawa. An important problem of this thesis, is that of holding exogenous variables constant, particularly the variable--the quality of management personnel. In order to find a relationship between the variable, management structure, all other variables have to be held reasonably constant. A variety of methodologies are used to draw information on the subject. Firstly, there is a review of literature available on the subject of port administration and systems of port administration. Herein, an appeal is made to the statements of professionals or "experts" in port administration. Secondly, a study is made of a series of reports on specific port operations throughout the world. These studies were classified according to (1) type of administrative structure, and (2) quality of port operations. A matrix was set up to correlate the findings. Thirdly, and finally, a field study was made (utilizing interview methodology) on two major ports of the region. The field study report, although admittedly shallow, attempted to analyze the ports around the foci. 1. Structure (also degree of autonomy), and 2. Performance.¹ The most basic conclusion to grow out of this thesis was that, by and large, major seaports are best run--most proficiently run--when they are run by professional management from the locality of the harbour, and through a structure of administration which is completely autonomous with regards to day-to-day operations, and relatively autonomous with regard to long-run planning. ¹ This is similar to what was done in the study of reports on world ports by the International Bank mentioned above.
Dolerite intrusion Hobart district, Tasmania
Creators: name: Leaman, DE
Publisher: name: University Of Tasmania
Year: 2023

description: Jurassic dolerite intrusions ot the Hobart district, Tasmania, have been examined geologically and gravimetrically in order to determine their form. The dolerite intrudes flat lying shallow marine Permian and continental Triassic rocks. A major problem was the resolution of more recent faulting superimposed upon Jurassic structures. The intrusions are the result or a limited series of injections (four or five). Each individual intrusion has an irregular flattened trumpet shape. Synchronous intrusions have interconnected to produce a cross-wave pattern in which each hollow represents the site or one or more massive feeders. The feeders are basically dykes up to a mile across, although some are pipe-like extensions or wedges from dykes, and most are related to pre-existing faults. Sheets have been initiated above feeder wedges at a point where effective intrusion pressure (about 7x10,gm/cm2) has exceeded the load pressure. Dislocation by fracturing was followed by hydrostatic intrusion. The actual form of the sheets, termed chonoliths, is determined at any place by any previous and concomitant fracturing. Fractures are controlled by rock heterogeneities, plastic confining beds, fluid content and distance from the feeder, or proximity of the tree surface. Each sheet is about l,000-1,500 feet thick. Initial intrusions are normally placed low in the sedimentary column, while later intrusions generally found a higher level. Ultimately a lava plateau could be produced if the magma supply was adequate, although no evidence exists for this feature in Tasmania. Extreme products of differentiation are to be found only in those parts of the intrusion ad3acent to, or above, a feeder. There is no evidence of assimilation within the area.

The catalog lists the original host object, compiles available redshifts and presents newly determined positions for the central (target) galaxy and its nearest companion(s). 127 collisional RING systems are illustrated and their components identified. All of the RINGS have plausible colliders identified; many are radial-velocity confirmed companions. Finally, we make note of the existence of a rare sub-class of RING galaxies exemplified by AM 2136-492, double/concentric RING galaxies. These objects are predicted by numerical simulations, but they appear to be quite rare and/or short-lived in nature.

Inter-Religious interaction in urban Australia: the influence of religious-identity on perceptions of 'the Other'
Creators: name: Chittock, EM
Publisher: name: University Of Tasmania
Year: 2023

description: This thesis explores perceptions of the religious 'Other' using symbolic interactionism as a theoretical framework in the sociology of religion, and a qualitative research approach of participant observations of eight worship gatherings: two Jewish, four Christian, and two Islamic; thirty-six in-depth semistructured interviews of affiliates from each religion; and textual analysis of political and mass media information. The thesis explores and provides insight into two areas of religious-related expression. The first is the nature of religious self-identity from affiliates of Jewish, Christian, and Islamic worship gatherings and secondly, from that basis, affiliates' perceptions of the religious 'Other' that arise in a context of religious diversity. This thesis finds that that religious identity is more complex than having a fixed and single affiliation. Pluralists exist who are fluid in their identity, affiliations, and practices. Some fundamentalists tolerate and even appreciate difference. Interfaith interactions are often conducted in a quiet and informal way between individuals and small groups, rather than in large and spectacular fashion. Those who encounter mystical spiritual types of experiences are also 'Other' because they, too, 'think and know differently'. This different way of knowing complements normally-accepted knowledge sources. Perceptions of 'the Other', then, range from outright rejection and antagonism by those firmly entrenched in their own beliefs; to ambivalence; and to respect and appreciation of difference for the opportunities opened for learning, expanding one's knowledge and perspective, and for creating an inclusive, shared, and diverse social context. The thesis finds that these perceptions of the religious 'Other' relate to perceptions of change, and are based on interpretations of 'right living' as contrasted with interpretations of 'wrong living'. As people encounter difference, which disturbs and threatens to undermine their own right ways, they act to remedy that disturbance. Social change has implications for religious self-identity and intentions of right living.

description: The fabrication of durable and low-cost nanostructured materials remains important in chemical, biologic and medicinal applications. Particularly, iron-based nanomaterials are of central importance due to the ‘noble’ features of iron such as its high abundance, low cost and non-toxicity. Herein we report a simple sol–gel method for the synthesis of novel iron–titanium nanocomposite-based material (Fe9TiO15@TiO2). In order to prepare this material, we made a polymeric gel using ferrocene, titanium isopropoxide and THF precursors. The calcination of this gel in air at 500◦C produced Fe-Ti bimetallic nanoparticles-based composite and nano-TiO2 as support. Noteworthy, our methodology provides an excellent control over composition, size and shape of the resulting nanoparticles. The resulted Fe-based material provides a sustainable catalyst for selective synthesis of anilines, which are key intermediates for the synthesis of several chemicals, dyes and materials, via reduction of structurally diverse and functionalized nitroarenes. © 2020 by the authors.

description: We consider the dynamics of a disordered p-spin model with p=2, analyzing the dynamics within Ruelle's thermodynamic formalism, We use an indicator of the dynamical activity to construct the relevant dynamical Gibbs ensemble. We prove that the dynamics in the low-temperature (spin glass) phase of the model take place at a second-order phase transition between dynamically active and inactive trajectories. We also show that the same behaviour is found in a related model of a three-dimensional ferromagnet.

description: One of the unifying concepts in the iron-pnictide superconductors, both for the mechanism of magnetic ordering and of unconventional order parameter character, has been the electron and hole Fermi surfaces that are approximately nested. Using the density functional methods that have predicted Fermi surfaces correctly in SrFe$_2$P$_2$, we find that the recently reported superconducting Sr$_2$VO$_3$FeAs, with $T_c$=37 K and no apparent competition between magnetism and superconductivity, possesses different Fermi surface geometry and character than previous classes of iron pnictides. The intervening layer (a V bilayer) gives rise to bands that cross the Fermi level. Coupling to the FeAs layer is small except for interaction along the zone boundary, however that coupling degrades the Fermi surface nesting. Sr$_2$VO$_3$FeAs, with its alternating layers of open shell atoms, deserves further close study that should help to understand the origin of the properties of iron pnictide compounds.

description: An ozone mini-hole is a synoptic-scale area of strongly reduced column total ozone, which undergoes a growth-decay cycle in association with baroclinic weather systems. The tracks of mini-hole events recorded during the TOMS observation period over the Northern Hemisphere provide a database for building anomaly fields of various meteorological parameters, following each mini-hole center in a Lagrangian sense. The resulting fields provide, for the first time, a complete mean Lagrangian picture of the three-dimensional structure of typical ozone mini-holes in the Northern Hemisphere. Mini-holes are shown to be associated with anomalous warm anticyclonic flow in the upper troposphere and cold cyclonic anomalies in the middle stratosphere. Ascending air columns occur upstream and descent downstream of the mini-hole centers. Band-pass filtering is used to reveal the transient synoptic nature of mini-holes embedded within larger scale circulation anomalies. Significant correlations between ozone and Ertel's potential vorticity on isentropes (IPV) both near the tropopause and in the middle stratosphere are shown and then utilized by reconstructing the Lagrangian analysis to follow local IPV anomalies instead of ozone minima. By using IPV as a proxy for ozone, the geopotential anomaly dipolar structure in the vertical characteristics of mini-holes is shown to result from a superposition of two largely independent dynamical components, stratospheric and tropospheric, typically operating on different time scales. Hence, ozone mini-holes may be viewed primarily as phenomena of coincidence.

description: Quasiparticle interference (QPI) in spectroscopic imaging scanning tunneling microscopy provides a powerful method to detect orbital band structures and orbital ordering patterns in transition metal oxides. We use the $T$-matrix formalism to calculate the QPI spectra for the unconventional metamagnetic system of Sr$_3$Ru$_2$O$_7$ with a $t_{2g}$-orbital band structure. A detailed tight-binding model is constructed accounting for features such as spin-orbit coupling, bilayer splitting, and the staggered rotation of the RuO octahedra. The band parameters are chosen by fitting the calculated Fermi surfaces with those measured in the angular-resolved photo-emission spectroscopy experiment. The calculated quasiparticle interference at zero magnetic field exhibits a hollow square-like feature arising from the nesting of the quasi-1d $d_{xz}$ and $d_{yz}$ orbital bands, in agreement with recent measurements by J. Lee {\it et al.} (Nature Physics {\bf 5}, 800 (2009)). Rotational symmetry breaking in the nematic metamagnetic state also manifests in the quasi-particle interference spectra.

description: Reproducibility of photocatalytic reactions, especially when conducted on small scale for improved turnover numbers with in situ formed catalysts can prove challenging. Herein, we showcase the problematic reproducibility on the example of attractive photocatalytic CO2 reduction utilizing [FeFe] hydrogenase mimics. These Fe complexes, well-known for their application in proton reduction reactions, were combined with a heteroleptic Cu photosensitizer and produced CO/H2/HCO2H mixtures of variable constitution. However, the reactions indicated a poor reproducibility, even when conducted with well-defined complexes. Based on our experience, we make suggestions for scientists working in the field of photocatalysis on how to address and report the reproducibility of novel photocatalytic reaction protocols. In addition, we would like to highlight the importance of studying reproducibility of novel reaction protocols, especially in the fields of photocatalytic water splitting and CO2 reduction, where TONs are widely used as the comparable measure for catalytic activity. © 2019 The Authors.

Retail price competition in Canadian whole life insurance
Creators: name: Mitchell, David Hoadley
Publisher: name: University of British Columbia
Year: 2011

description: Problems of price analysis and price comparisons at the retail level in whole life insurance are so complex as to be well beyond comprehension to the average purchaser. In addition to the initial difficulties arising from the combination of savings and insurance protection which exist in whole life insurance policies many variables exhibit influence in the analysis of retail whole life insurance prices. The determination of price is no easy task but is ably accomplished by the level-price method which is utilized in this study. Competition, it is often expressed, should function as a sufficient deterrent against the charging of excessive prices. From economic theory the concept of effective competition dictates that prices need not be completely uniform but that they ought not to exhibit substantial diversity and that they should be flexible. The flexibility of prices in whole life insurance is restricted, by the nature of the product, to changes on an annual basis. Evidence from this study, based on 1967 data, indicates that substantial price disparity between different companies is existent in various types of whole life insurance policies offered in Canada. Competition however, operates as well on variables other than price. The extent to which the existent price disparity reflects the costs of the added variables is not completely clear. While this study only views the price competition situation at one point in time, and is therefore restricted from the advantages of conclusions based on broad foundations in time, it nevertheless appears evident that while no conclusions can be made here on competition as a whole, competition on the basis of price alone is less than wholly effective.

Accounting for intangible assets, firm life cycle and the value relevance of intangible assets
Creators: name: Jaafar, H
Publisher: name: University Of Tasmania
Year: 2023

description: This study examines the relationship between accounting choice for intangible assets and their value relevance as well as the moderating effect of firm life cycle on this relationship, in the pre- and post-Australian Equivalents to International Financial Reporting Standards (AIFRS) periods. In the pre-AIFRS period, Australian firms enjoyed wide discretion in accounting for intangible assets. However, with the adoption of AIFRS in 2005, managerial discretion in accounting for the assets has become more restrictive. This allows the impacts of alternative accounting practices in these two periods to be investigated. The sample used in this study consists of 900 and 1,225 firm-years for the pre and post AIFRS period, respectively. Sample firms are classified into three life cycle stages; Growth, Mature and Decline, based on Anthony and Ramesh's (1992) classification method. Four regression models based on the Ohlson (1995) valuation model are used in the tests of value relevance. The findings indicate that during the pre-AIFRS period, capitalised identifiable intangible assets are regarded by the Australian market as value relevant. The results also suggest that although there is a significant difference in value relevance between Decline and Mature firms, the same effect is not present between Growth and Mature firms. Further, the results indicate that identifiable intangible assets for Growth and Mature firms are value relevant but not for Decline firms. Although the findings provide support to previous studies on the use of accounting choice as a signalling mechanism, there is also evidence to suggest that it is not employed homogeneously across firms. A comparison between the pre- and post-AIFRS period suggests that the market attaches higher value relevance to identifiable intangible assets after the adoption of AIFRS. The findings also suggest that AIFRS implementation has led to an increase in the value relevance in all three firm life cycle stages and that there is no significant difference between these stages. Nonetheless, the impact of AIFRS implementation is more substantial for Decline firms with evidence of value relevance found only in the post-AIFRS period. This suggests that the concerns over a more restrictive accounting treatment for intangible assets following the adoption of AIFRS could lead to firms providing less value-relevant information might be overstated and unwarranted. The findings presented in this study should be useful to both researchers and accounting standard setters in the ongoing debate on allowing managerial discretion with regards to accounting for intangible assets, particularly following the adoption of AIFRS.

description: We use functional renormalization group methods to study gravity minimally coupled to a free scalar field. This setup provides the prototype of a gravitational theory which is perturbatively non-renormalizable at one-loop level, but may possess a non-trivial renormalization group fixed point controlling its UV behavior. We show that such a fixed point indeed exists within the truncations considered, lending strong support to the conjectured asymptotic safety of the theory. In particular, we demonstrate that the counterterms responsible for its perturbative non-renormalizability have no qualitative effect on this feature.

description: Promoter (Cr, Mo and W) modified Ni/ZSM-5 catalysts were explored in the vapor phase conversion of γ-valerolactone (GVL) to ethyl valerate (EV; gasoline blender) at atmospheric pressure. Among the three different promoters (Cr, Mo and W) tested the Mo-modified catalyst was found to be the best candidate. In addition, this catalyst was found to be stable up to 50 h reaction time with an insignificant decrease in activity. The good catalytic performance is related to an optimal ratio of acid and hydrogenation functions provided by Ni2+ and Ni0, respectively. In situ FTIR spectroscopic studies revealed a strong adsorption of GVL on all catalysts which quickly reacts with dosed ethanol by formation of EV, most pronounced on the Mo-modified catalyst, while VA was identified as side product. These findings suggest the preferred GVL ring opening by cracking the C−O bond on the methyl side of the GVL molecule on this type of catalysts leading to pentenoic acid as intermediate, which is quickly hydrogenated and esterified. © 2019 The Authors.

Mapping ruderality: Heading for design

description: A newly acquired property in the Tamar Valley prompted the research, Mapping ruderality: heading for design. With ownership comes a natural inclination to make change, to imprint one's mark on the land. In order to inform decision‚ÄövÑv™making and to maximize understanding of this new place called home, my research maps the cultural and natural phenomena of the site and its surrounds as a direct response to prevailing concerns. Working at the interface of art and design, one informs the other, setting the conditions for change. Although the focus is on a particular parcel of land ‚Äö- a ruderal landscape of dilapidated timber sheds and rampant blackberries, neglected for many years since its pioneering, productive past ‚Äö- the modus operandi (mapping and hermeneutics) may be applied more generally. Inspired, in part, by landscape architect James Corner, hermeneutics is presented as a means to counter the demise of substantive landscape design. The evolving art of mapping, from navigation to conceptualisation, is considered through its complementary parts ‚Äö- scale, projection, triangulation, toponomy, grids. Together, mapping and hermeneutics interpret the microcosm of the former orchard and its extended relationships in the valley. Traditional cartography has influenced the method which often presents as phenomenological or absorptive mapping. Hermeneutic enquiry allows for open interpretation, for an understanding of the whole by reference to its individual parts, and vice versa. Overall, the works constitute a 'bringing to attention' of site conditions, which we are compelled to modify and control (owning, naming, limiting, exploiting). The process is informed predominantly by the works of Janet Laurence, Maya Lin, Fujiko Nakaya, Anne Wilson and Julie Mehretu, all of whom offer new readings of landscape as an expression of ideas and a way into design. An alternative cartographic practice which infuses rational, detached observation with the subjectivity of experience takes cues from the ruderal state to engage with current issues in land use and design, and augments the tradition of map‚ÄövÑv™making in place‚ÄövÑv™making. Graticules and rhumb lines of individual works converge in a larger exploratory grid to reveal the distortions, biases, influences and ambiguities that are inherent in the project of mapping. Together hermeneutics and mapping locate the research specifically here, and, at a remove, should be comprehended as (anywhere) there.

description: The effect of different AlR3 activators (R=methyl, ethyl, isobutyl, n-octyl) has been studied in comparison to modified methylaluminoxane (MMAO) by operando EPR as well as by in situ UV-vis, ATR-IR and XANES/EXAFS spectroscopy during oligomerization of ethylene at 20 bar and 40 °C with a homogeneous Cr complex catalyst formed in situ upon mixing a Cr(acac)3 precursor, a Ph2PN(iPr)PPh2 ligand (PNP) and the activator. Coordination of PNP to Cr(acac)3 is initiated only in the presence of an activator. Highest 1-octene productivity (detected during operando EPR measurements) was obtained with MMAO which promotes bidentate coordination of the ligand to form an active (PNP)CrII(CH3)2 chelate complex. Rising bulkiness of R in AlR3 leads to only monodentate coordination of PNP to the Cr center by one P atom and increasing reduction to CrI to a maximum extend of around 30 % for AlOct3. This lowers the catalytic performance, which is mainly governed by the mode of PNP coordination rather than by the CrI content. ©2019 The Authors. Published by Wiley-VCH Verlag GmbH & Co. KGaA.
The crossover regime for the weakly asymmetric simple exclusion process

description: We consider the asymmetric simple exclusion process in one dimension with weak asymmetry (WASEP) and 0-1 step initial condition. Our interest are the fluctuations of the time-integrated particle current at some prescribed spatial location. One expects a crossover from Gaussian to Tracy-Widom distributed fluctuations. The appropriate crossover scale is an asymmetry of order $ε^{-1/2}$, times of order $ε^{-2}$, and a spatial location of order $ε^{-3/2}$. For this parameter window we obtain the limiting distribution function of the integrated current in terms of an integral over the difference of two Fredholm determinants. For large times, on the scale $ε^{-2}$, this distribution function converges to the one of Tracy-Widom.
