À LIRE ET À VOIR, ENTRE MOT ET IMAGE: SELECTED TRANSLATIONS OF WORKS BY HENRI MICHAUX
Creators: name: Arend, Victoria
Publisher: name: University of Massachusetts Amherst
Year: 2014

description: This Master’s thesis investigates the language of words and images in the work of Belgian poet and painter Henri Michaux (1899-1984) through the practice of translation. I have chosen to translate texts that serve as critical and poetic inquiries into the nature of verbal and visual representation. In the critical introduction preceding the translations, I analyze Michaux’s relationship to the languages of words and images in the selected works. The selected translations appear in two sections: “On Words and Images” and “Images in Words.” In the first, I translate selections from Michaux’s reflective works on the practice of painting and writing. These include the essay “En pensant au phénomène de la peinture,” first published in Peintures et dessins (1946) and selections from Émergences-résurgences (1972).  In the second, I translate selections from works of ekphrastic poetry, including “Dessins commentés,” first published in La nuit remue (1935), “Aventures de lignes,” from Passages (1937-1963) (1950, 1963), Lecture par Henri Michaux de huit lithographies de Zao Wou-Ki (1950) and En rêvant à partir de peintures énigmatiques (1972). I propose that these texts reflect Michaux’s hybrid view of representation. They embody a search for an ideal language that is neither purely verbal nor visual, calling for both words and images.

description: In the background of a charged AdS dilaton black hole, we investigate the movement of a self-graviting 3-brane and relevant holographic effects as the brane move close to the AdS boundary. The induced metric on brane corresponds to an exact FLRW geometry, while the evolution of brane is determined by Israel junction condition and the effective Einstein field equation on brane together. When the brane approaches the AdS boundary, AdS/CFT correspondence implies that a radiation dominated FLRW-universe ($P=\frac{1}{3}ρ$) should be given. According to the holographic renormalization procedure, we involve an appropriate surface counterterm into the gravitational action for achieving $P=\frac{1}{3}ρ$ on brane. This surface counterterm also plays a important role in caculating the mass of charged AdS dilaton black hole. Finally, we obtain the thermodynamic quantities and give an extend Cardy-Verlinde formula on brane.

description: The second data release of the Gaia mission has revealed, in stellar velocity and action space, multiple ridges, the exact origin of which is still debated. Recently, we demonstrated that a large Galactic bar with pattern speed 39 km/s/kpc does create most of the observed ridges. Among those ridges, the Hercules moving group would then be associated to orbits trapped at the co-rotation resonance of the bar. Here we show that a distinctive prediction of such a model is that the angular momentum of Hercules at the Sun's radius must significantly decrease with increasing Galactocentric azimuth, i.e. when getting closer to the major axis of the bar. We show that such a dependence of the angular momentum of trapped orbits on the azimuth would on the other hand not happen close to the outer Lindblad resonance of a faster bar, unless the orbital distribution is still far from phase-mixed, namely for a bar perturbation younger than ~ 2 Gyr. Using Gaia DR2 and Bayesian distances from the StarHorse code, and tracing the average Galactocentric radial velocity as a function of angular momentum and azimuth, we show that the Hercules angular momentum changes significantly with azimuth as expected for the co-rotation resonance of a dynamically old large bar.

Productivity Analysis

description: Preferences for monetary and non-monetary plant traits influence modem crop variety adoption decisions of farmers. To enhance adoption probability of modem crop varieties, it is necessary to identify and focus research on traits that significantly contribute to utility while de-emphasizing insignificant plant attributes. This paper illustrates the potential for applying conjoint analysis to aid the design and targeting of client-responsive modem crop varieties. Farmers ranked eight orthogonally-derived plant trait combinations used in an illustrative example. Utilities were estimated using the choice-probability-based method of ordered probit. Results showed that conjoint analysis can differentiate significant and non-significant traits of modem crop varieties. The usefulness of applying conjoint analysis over identifiable disaggregated groups of a sample was also evident. Future application of conjoint analysis to the design and targeting of modem crop varieties should carefully consider sample composition and size to permit the estimation of relevant sub-models for desired farmer segments.

description: There has been considerable reform of the Australian natural gas industry. An element of this reform has been the introduction of ‘contestability’ — allowing customers to select their retailer of natural gas. The potential benefits and risks associated with this policy are presented and the key issues involved in the implementation of contestable natural gas market are explored. Aside from the potential risks, the policies that have been introduced in order to prevent potential difficulties are examined. It is found that, while increased retail competition is an important element of the reform process, the potential benefits are limited in the absence of further upstream reform.

description: In the Philippines, farmers have often cited the lack of access to capital as the main impediment to increasing agricultural production. Production and marketing ex penditures of smallholder farmers are predominantly financed by traders and household savings. Product, input and credit markets are strongly interlinked and involve both formal and informal sectors. This research aims to understand the existing financial systems available to smallholder livestock farmers in Western Leyte, Philippines. It investigates the constraints and problems faced by livestock farmers in relation to access to capital, identifies opportunities to overcome credit constraints and formulates recommendations for improving access of smallholder farmers to credit.

description: Bird plumage hosts a diverse microbial community, including microbes capable of degrading the β-keratin in feathers (i.e. feather-degrading bacteria). The prevalence and effects of feather-degrading bacteria have primarily been studied in the Northern Hemisphere, and knowledge of the occurrence of these bacteria on Southern Hemisphere bird species is lacking. We explored the prevalence of feather-degrading bacteria on wild birds in Australia by sampling feathers from 254 individuals representing 25 species. First, to determine the total plumage bacterial load, we sampled bacteria from three body regions and identified and enumerated three presumed feather-degrading Bacillus spp. (B. licheniformis, B. cereus, and B. subtilis) based on morphology. Second, we collected a feather from each bird and in laboratory tests confirmed the presence of feather-degrading bacteria. Third, we tested for a relationship between the number of presumed feather-degrading Bacillus spp. counted and the presence of feather-degrading bacteria on the following variables: habitat type, foraging behaviour, flocking status, and feather wear. We found 85% of birds sampled harboured presumed Bacillus spp. Of the feather samples that tested positive for Bacillus in lab experiments, 62% were confirmed as feather-degrading Bacillus spp. The total plumage bacterial load varied with habitat type, with birds in heath habitats harbouring fewer bacteria. This study is the first report of feather-degrading bacteria on the plumage of wild Australian birds in vivo.

description: Abell 2163 at $z \simeq 0.201$ is one of the most massive galaxy clusters known, very likely in a post-merging phase. Data from several observational windows suggest a complex mass structure with interacting subsystems, which makes the reconstruction of a realistic merging scenario very difficult. A missing key element in this sense is unveiling the cluster mass distribution at high resolution. We perform such a reconstruction of the cluster inner total mass through a strong lensing model based on new spectroscopic redshift measurements. We use data from the Multi Unit Spectroscopic Explorer (MUSE) on the Very Large Telescope (VLT) to confirm 12 multiple images of 4 sources with redshift values from 1.16 to 2.72. We also discover four new multiple images and identify 29 cluster members and 35 foreground and background sources. The resulting galaxy member and image catalogs are used to build five cluster total mass models. The fiducial model consists of 111 small-scale subhalos plus a diffuse component, which is centered $\sim2$ arcseconds away from the BCG belonging to the east Abell 2163 subcluster. We confirm that the latter is well represented by a single, large-scale mass component. Its strong elongation towards a second (west) subcluster confirms the existence of a preferential axis, corresponding to the merging direction. From the fiducial model, we extrapolate the cumulative projected total mass profile and measure a value of $M(<300\,$kpc$) = 1.43^{+0.07}_{-0.06}\times 10^{14}\,$M$_{\odot}$, which has a significantly reduced statistical error compared with previous estimates, thanks to the inclusion of the spectroscopic redshifts. Our strong lensing results are very accurate: the model-predicted positions of the multiple images are, on average, only $0.15$ arcseconds away from the observed ones.

Performance of Circular Reinforced Concrete Bridge Piers Subjected to Vehicular Collisions
Creators: name: Gomez, Nevin L
Publisher: name: University of Massachusetts Amherst
Year: 2014

description: Vehicle collisions with bridge piers can result in significant damage to the support pier and potentially lead to catastrophic failure of the whole structure. The Nation’s aging infrastructure suggests that many structures no longer meet current design standards, placing many bridge susceptible to failure if subjected to an extreme loading event. This research aims to study the structural response of reinforced concrete bridge piers subjected to vehicle collisions. A sensitivity analysis is conducted to observe the causes of shear and bending failures of bridge piers subjected to vehicle collision. Parameters, such as pier diameter, transverse reinforcement spacing, vehicle impact velocity, pile cap height, and multi-pier configuration, are investigated in this study.
The finite element code LS-DYNA is utilized to simulate and analyze the vehicle collisions to obtain accurate and detailed results. The vehicle models offered by the National Crash Analysis Center and the National Transportation Research Center, Inc. are used to conduct this research. The finite element modeling controls and material properties are validated by conducting an impact drop hammer experiment. The bridge pier collision models are validated by comparing vehicle damage and impact forces with published research results. Conservation of energy is also checked to assure stability within the impact simulation.
A sensitivity analysis suggests that different pier parameters have a profound effect on failure modes and distribution of impact forces. Piers with large stiffness result in high impact forces, low lateral displacements, and high resistance to shear forces and bending moments. A performance-based analysis shows that bridge piers can be designed using damage ratios associated with particular damage states.
Effects of Developmental Exposures of Two Emerging Environmental Toxicants on Estrogen-Sensitive Endpoints

Publisher: name: University of Massachusetts Amherst
Year: 2015

description: Thousands of synthetic chemicals have been released into the environment, causing widespread exposures of wildlife and humans alike. Some of these chemicals are known to disrupt aspects of hormone action thus inducing abnormalities in endocrine tissues and organs. Bisphenol S (BPS) and tetrabromobisphenol A (TBBPA), two largely unstudied chemicals commonly used in consumer products, are suspected to have endocrine disrupting properties based on their similar chemical structures to known endocrine disrupting chemicals (EDCs). To determine whether developmental exposure to BPS or TBBPA induced abnormalities in the ovary, mice were administered oil, BPS or TBBPA during pregnancy and lactation. The ovaries of female offspring were examined for gross morphological, immunohistological and gene expression differences at postnatal day (PND) 22 and week 16. To determine whether these exposures alter responses to hormones, two females from each litter were administered either oil or ethinyl estradiol (EE2) from PND 19-21. Our study identified significant differences in ovarian follicular formation and gene expression after developmental TBBPA and BPS exposures. Most effects were observed at PND22 (pre-puberty), and were apparent after the EE2 challenge, suggesting that changes induced by BPS and TBBPA are age- and hormone- dependent. Our results are consistent with the hypothesis that TBBPA and BPS are EDCs; that these compounds can disrupt development of the ovary; and that the observed effects of TBBPA and BPS exposure are similar to risk factors for ovarian diseases including cancer. These findings may indicate that widespread exposures to BPS and TBBPA could have implications for public health.

description: Purpose - Providing quality low-cost high-rise residential housing for poor households remains a major concern worldwide and especially in Malaysia. Despite government effort to maintain the quality of the housing through the Housing Maintenance Program and 1Malaysia Maintenance Fund Program (TP1M), the maintenance industry is still faced with serious housing quality problems in terms of facilities, one of which is the lift system. As the most expensive and important transportation system in a high-rise building, a lift system requires regular maintenance and inspection to provide safe and effective service to occupants. Unfortunately, most lift systems in Malaysia are not effectively maintained. The purpose of this paper is to examine contributing factors to the breakdown of lift systems, which greatly affect resident satisfaction in low-cost high-rise residential buildings.Design/methodology/approach - Semi-structured interviews were conducted with three stakeholders involved in maintenance management to identify the common causes of lift breakdown. Subsequently, a questionnaire survey was used to investigate resident satisfaction with the system.Findings - The results demonstrate vandalism as the most common cause for the frequent breakdown of lift system in low-cost housing. The study also reveals that there is a significant relationship between system breakdown rate and residents' satisfaction.Originality/value - The paper concludes with the recommendation that stakeholders, including both maintenance personnel and residents, should commit themselves to ensuring that the use and care of lift system are correct
Charge current in ferromagnet-superconductor junction with pairing state of broken time-reversal symmetry

description: We calculate the tunneling conductance spectra of a ferromagnetic metal/insulator/superconductor using the Blonder-Tinkham-Klapwijk (BTK) formulation. Two possible states for the superconductor are considered with the time reversal symmetry ($\cal{T}$) broken, i.e., $d_{x^2-y^2}+is$, or $d_{x^2-y^2}+id_{xy}$. In both cases the tunneling conductance within the gap is suppressed with the increase of the exchange interaction due to the suppression of the Andreev reflection. In the $(d_{x^2-y^2}+is)$-wave case the peaks that exist when the ferromagnet is a normal metal in the amplitude of the s-wave component due to the bound state formation are reduced symmetrically, with the increase of the exchange field, while in the $(d_{x^2-y^2}+id_{xy})$-wave case the residual density of states within the gap develops a dip around E=0 with the increase of the exchange field. These results would be useful to discriminate between $\cal{T}$-broken pairing states near the surface in high-$T_c$ superconductors

description: A modified periodic boundary condition adequate for non-hermitian topological systems is proposed. Under this boundary condition a topological number characterizing the system is defined in the same way as in the corresponding hermitian system and hence, at the cost of introducing an additional parameter that characterizes the non-hermitian skin effect, the idea of bulk-edge correspondence in the hermitian limit can be applied almost as it is. We develop this framework through the analysis of a non-hermitian SSH model with chiral symmetry, and prove the bulk-edge correspondence in a generalized parameter space. A finite region in this parameter space with a nontrivial pair of chiral winding numbers is identified as topologically nontrivial, indicating the existence of a topologically protected edge state under open boundary.

A relativistic hadronic model with mesons, nucleons, and Delta(1232)isobars is applied. A substantial increase of the widths for the decays omega -> pi gamma* and rho -> pi gamma* is found for photon virtualities in the range 0.3-0.6 GeV. This enhancement has a direct importance for the description of dilepton yields obtained in relativistic heavy-ion collisions.

description: Recent individual studies have indicated that ultra-processed food (UPF) consumption may be associated with the incidence of chronic kidney disease (CKD). We conducted a systematic review and meta-analysis based on those longitudinal studies evaluating the relationship between UPF consumption and the risk of incident CKD, and synthesizing the results. PubMed, Embase, The Cochrane Library, Web of Science, and Scopus were searched from inception through 22 March 2023. Any longitudinal studies evaluating the relationship between UPF consumption and the risk of incident CKD were included. Two researchers independently conducted the literature screening and data extraction. RR and its 95% CI were regarded as the effect size. The Newcastle–Ottawa Scale (NOS) was applied to assess the quality of the studies included, and the effect of UPF consumption on the risk of incident CKD was analyzed with STATA version 15.1. This study’s protocol was registered in PROSPERO (CRD42023411951). Four cohort studies with a total of 219,132 participants were included after screening. The results of the meta-analysis suggested that the highest UPF intake was associated with an increased risk of incident CKD (RR = 1.25; 95% CI: 1.18–1.33). High-dose UPF intake was associated with an increased risk of incident CKD. However, the underlying mechanisms remain unknown. Thus, more standardized clinical studies and further exploration of the mechanisms are needed in the future.

description: LUSIFER is a Monte Carlo event generator for all processes e+e-->6fermions, which is based on the multi-channel Monte Carlo integration technique and employs the full set of tree-level diagrams. External fermions are taken to be massless, but can be arbitrarily polarized. The calculation of the helicity amplitudes and of the squared matrix elements is presented in a compact way. Initial-state radiation is included at the leading logarithmic level using the structure-function approach. The discussion of numerical results contains a comprehensive list of cross sections relevant for a 500GeV collider, including a tuned comparison to results obtained with the combination of the WHIZARD and MADGRAPH packages as far as possible. Moreover, for off-shell top-quark pair production and the production of a Higgs boson in the intermediate mass range we additionally discuss some phenomenologically interesting distributions. Finally, we numerically analyze the effects of gauge-invariance violation by comparing various ways of introducing decay widths of intermediate top quarks, gauge and Higgs bosons.

description: This talk describes some recent results [16] regarding the problem of uniqueness in the large (also known as strong cosmic censorship) for the initial value problem in general relativity. In order to isolate the essential analytic features of the problem from the complicated setting of gravitational collapse in which it arises, some familiarity with conformal properties of certain celebrated special solutions of the theory of relativity will have to be developed. This talk is an attempt to present precisely these features to an audience of non-specialists, in a way which will hopefully fully motivate a certain characteristic initial value problem for the spherically-symmetric Einstein-Maxwell-Scalar Field system. The considerations outlined here leading to this particular initial value problem are well known in the physics relativity community, where the problem of uniqueness has been studied heuristically [1, 22] and numerically [2, 3]. In [16], the global behavior of solutions to this IVP, in particular, the issue of uniqueness, is mathematically completely understood. A statement of the relevant Theorems is included in Section 9. Only a sketch of the ideas of the proof is provided here, but the readers may refer to [16] for details.

Pre-pregnancy BMI and Preterm Birth Among Hispanic Teens
Creators: name: Hope, Allison C
Publisher: name: University of Massachusetts Amherst
Year: 2015

description: Preterm birth affects 12% of infants in the United States annually and is the main contributor to infant deaths and long-term neurological disabilities in offspring. Obesity is a growing problem in the U.S., and is increasingly being considered a major risk factor for adverse health outcomes. Puerto Rican teenagers have disproportionately high rates of preterm birth and obesity when compared to non-Hispanic White teenagers. Studies evaluating risk factors for preterm birth among adolescents are sparse, have inconsistent findings, and were conducted among predominantly non-Hispanic populations. Therefore, we investigated the association between BMI and preterm birth among the 419 teenage (ages 16-19) participants in Proyecto Buena Salud, a prospective cohort study of predominantly Puerto Rican prenatal care patients in Massachusetts. Pre-pregnancy BMI was abstracted from medical records and defined using CDC adolescent BMI-for-age percentile categories. Preterm birth classifications were abstracted from the delivery record and confirmed by the study obstetrician. Seventy-six (18%) participants were overweight and 58 (14%) were obese. A total of 49 (11.7%) preterm births were observed, consisting of 36 (73%) spontaneous and 13 (27%) medically indicated. After adjusting for pregnancy complications, previous preterm birth, age, acculturation, and gestational weight gain, obese teens had a reduced odds of total preterm birth (OR: 0.12, 95% CI: 0.02, 0.61) and had a mean gestational age at delivery of 0.9 weeks higher (95% CI: 0.19, 1.56) as compared to normal weight teens. When evaluating preterm birth by subtype, overweight/obese teens had a reduced odds of spontaneous (OR: 0.36, 95% CI: 0.13, 1.02) and medically indicated (OR: 0.054, 95% CI: 0.004, 0.70) preterm birth compared to normal weight teens. This study adds to the body of literature on the impact of obesity on birth outcomes and extends this work to Hispanic teenagers.

description: Maintaining facilities and services of high-rise residential buildings is crucial in order to ensure the buildings operate optimally and achieve better user satisfaction. The purpose of this research is to deal with the appropriate maintenance interval for two different group of facilities and services namely essential and value-added specifically for high-rise residential buildings. Questionnaire survey was conducted among maintenance personnel who manage high-rise housing throughout Peninsular Malaysia. A total of 321 returned questionnaires were considered valid and analysed to rank the maintenance interval for the variables identified from literature review. The result revealed that different type of building facilities and services has different maintenance interval. It is also proven via Friedman test that the maintenance interval of facilities and services is significantly different. It is mainly because essential facilities and services are vital to support the building user daily routine. Thus, the maintenance personnel should plan and execute maintenance work based on the appropriate maintenance interval. Since this research only compares the differences of maintenance interval for different building facilities and services in common practice, further research is recommended to investigate the relationship between maintenance intervals and its performance in terms of cost and quality.

description: The goal of the paper is to identify the main drivers to the integrated management system (IMS) in small and medium size enterprises (SME) in Lithuania. For the survey, methods of the research were used: a meta-analysis, an analysis of statistical data, CEOs interviewing. Representatives from 124 enterprises were interviewed. Generalizing research findings, it could be pointed out that SME in Lithuania are successfully implementing IMS into their practice. The biggest benefit IMS gives in fields of documentation management of standards being realized, quality management standard realization, environment protection, organization’s image boosting and increase of competitiveness. The largest obstacle for a successful IMS realization is a lack of employees’ motivation to behave in a new way when IMS is implemented. There are more noticeable problems, such as lack of manager’s capability of IMS realization into the practice, difficulties with coordinating different standards and high cost of system standardization. It should be marked that the research participants emphasized the same barriers as the researchers mention in their research reports on IMS. Thus IMS development should be considered not only by the practitioners themselves, but also by IMS experts and researchers. The article gives value both to professionals and to scientists who are interested in practice of integrated management systems and in management particularities arrived on the cultural differences.

description: In this paper we discuss the Casimir effect in a small cavity, freely falling from spatial infinity in spacetime geometry outside of a Schwarzschild black hole. Our main goal is to search for possible changes in the vacuum energy, as well as particle creation inside the falling cavity, with respect to a comoving observer. Working in the Lemaître chart and assuming a cavity size $L$ much smaller than the Schwarzschild radius ($L/r_g\ll 1$), we solve the Klein-Gordon equation for a massless scalar field confined within the cavity in the reference frame of the comoving observer. We follow Schwinger's proper time approach, evaluating the one-loop effective action for the field in the falling cavity hence evaluating the corrections to the vacuum energy. We find a small reduction in the absolute value of Casimir energy as the cavity approaches the black hole horizon due to the changing spacetime geometry. Since the spacetime geometry for the cavity changes dynamically, we further find the energy density of the created particles due to the dynamical Casimir effect. These dynamical contributions exactly match the deficit to the static Casimir energy. Combined, the observer measures a net increase in energy within the cavity as she falls.

description: The signature of positron annihilation, namely the 511 keV $γ$-ray line, was first detected coming from the direction of the Galactic center in the 1970's, but the source of Galactic positrons still remains a puzzle. The measured flux of the annihilation corresponds to an intense steady source of positron production, with an annihilation rate on the order of $\sim10^{43}$~e$^{+}$/s. The 511 keV emission is the strongest persistent Galactic $γ$-ray line signal and it shows a concentration towards the Galactic center region. An additional low-surface brightness component is aligned with the Galactic disk; however, the morphology of the latter is not well constrained. The Compton Spectrometer and Imager (COSI) is a balloon-borne soft $γ$-ray (0.2--5 MeV) telescope designed to perform wide-field imaging and high-resolution spectroscopy. One of its major goals is to further our understanding of Galactic positrons. COSI had a 46-day balloon flight in May--July 2016 from Wanaka, New Zealand, and here we report on the detection and spectral and spatial analyses of the 511 keV emission from those observations. To isolate the Galactic positron annihilation emission from instrumental background, we have developed a technique to separate celestial signals utilizing the COMPTEL Data Space. With this method, we find a 7.2$σ$ detection of the 511 keV line. We find that the spatial distribution is not consistent with a single point source, and it appears to be broader than what has been previously reported.

description: We present a theory of the anomalous Hall effect in ferromagnetic (Mn,III)V semiconductors. Our theory relates the anomalous Hall conductance of a homogeneous ferromagnet to the Berry phase acquired by a quasiparticle wavefunction upon traversing closed paths on the spin-split Fermi surface of a ferromagnetic state. It can be applied equally well to any itinerant electron ferromagnet. The quantitative agreement between our theory and experimental data in both (In,Mn)As and (Ga,Mn)As systems suggests that this disorder independent contribution to the anomalous Hall conductivity dominates in diluted magnetic semiconductors.

description: Electromagnetically neutral dark sector particles may directly couple to the photon through higher dimensional effective operators. Considering electric and magnetic dipole moment, anapole moment, and charge radius interactions, we derive constraints from stellar energy loss in the Sun, horizontal branch and red giant stars, as well as from cooling of the proto-neutron star of SN1987A. We provide the exact formula for in-medium photon-mediated pair production to leading order in the dark coupling, and compute the energy loss rates explicitly for the most important processes, including a careful discussion on resonances and potential double counting between the processes. Stringent limits for dark states with masses below $3\,$keV ($40\,$MeV) arise from red giant stars (SN1987A), implying an effective lower mass-scale of approximately $10^9\,$GeV ($10^7\,$GeV) for mass-dimension five, and $100\,$GeV ($2.5\,$TeV) for mass-dimension six operators as long as dark states stream freely; for the proto-neutron star, the trapping of dark states is also evaluated. Together with direct limits previously derived by us in Chu et al. (2018), this provides the first comprehensive overview of the viability of effective electromagnetic dark-state interactions below the GeV mass-scale.

Mesoscopic theory for systems with competing interactions near a confining wall

description: Mesoscopic theory for self-assembling systems near a planar confining surface is developed. Euler- Lagrange (EL) equations and the boundary conditions (BC) for the local volume fraction and the correlation function are derived from the DFT expression for the grand thermodynamic potential. Various levels of approximation can be considered for the obtained equations. The lowest-order nontrivial approximation (GM) resembles the Landau-Brazovskii type theory for a semiinfinite system. Unlike in the original phenomenological theory, however, all coefficients in our equations and BC are expressed in terms of the interaction potential and the thermodynamic state. Analytical solutions of the linearized equations in GM are presented and discussed on a general level and for a particular example of the double-Yukawa potential. We show exponentially damped oscillations of the volume fraction and the correlation function in the direction perpendicular to the confining surface. The correlations show oscillatory decay in directions parallel to this surface too, with the decay length increasing significantly when the system boundary is approached. The framework of our theory allows for a systematic improvement of the accuracy of the results.
What's it all about? What does good economic management mean in Australia

description: This paper considers the question of what is meant by good economic management. In addressing this question it considers both the long term perspective and the international perspective. Australia's post GFC experience is contrasted favourably with a broad range of other countries, especially countries that cut government spending as their economies slowed. As Figure 1 shows Australia's economic performance as measured by GDP has been superior to the rest of the developed world, especially when compared to countries that pursued cuts in government spending as their economies slowed. The paper also considers the long term economic management of the major parties through the prism of the broad economic theories to which they have subscribed over time. It argues that, with occasional deviations, Labor’s macroeconomic policy stance has been Keynesian ever since the Working Nation package introduced in the aftermath of the 1990-91 recession.

description: There has been a rapid increase in global expenditure on information technology and there is still much to learn about its effects on productivity, welfare and social change. At the macro-level, it has been estimated that Internet-related value accounts for as much as 7% of GDP of some OECD economies. As discussed, two basic methods have been used to estimate the contribution of ICT to the growth in GDP. Estimates of this vary considerably but it seems that ICT’s contribution is increasing. Currently, GDP is expected to increase by about 1% for a 10% rise in ICT-capital. All industries have had added value as a result of the introduction of ICT but the overall aggregate effect is largest for the tertiary (service) sector. It is shown how the Internet can increase economic productivity (1) by reducing input costs and (2) raising allocative efficiency within enterprises. Other ways in which Internet access can increase economic welfare are via reduced market transaction costs and a decline in material and transport costs as well as by increasing the variety of available commodities. These aspects are analyzed and discussed critically. Attention is also given to the employment consequences of the use of ICT, associated health issues, and the impacts of ICT on social interaction and the environment. It is suggested that the use of the Internet for consumption may exceed it use for production. Additional matters touched on are the consequences for economic performance of ICT in education and research and in the health industry, as well as the comparative benefit of ICT to rural residents compared to city-dwellers. In conclusion, it is noted that not all IT depends on the Internet and that non-Internet IT has had little economic attention.
