description: I have used different econometric models (OLS, probit and multinomial logit selection) to analyses factors leading to poverty. The main emphasis of the study is to model determinants of standard of living in Addis Ababa using two-stage estimation technique. In the first step, a multinomial logit model is applied to distinguish between three socio-economic groups. The second stage regression, determinants of standard of living (i.e. total household expenditure per adult equivalent per month) are identified after incorporating the correction term for sample selectivity using the Lee-Heckman method. Among others, variables such as education, access to credit, employment status, gender, marital status and food shortage experience are significant determinants of welfare.

Evidence for a Millisecond Pulsar in 4U 1636-53 During a Superburst

description: We report the discovery with the Proportional Counter Array on board the Rossi X-ray Timing Explorer of highly coherent 582 Hz pulsations during the February 22, 2001 (UT) ``superburst'' from 4U 1636-53. The pulsations are detected during an 800 s interval spanning the flux maximum of the burst. Within this interval the barycentric oscillation frequency increases in a monotonic fashion from 581.89 to 581.93 Hz. The predicted orbital motion of the neutron star during this interval is consistent with such an increase as long as optical maximum corresponds roughly with superior conjunction of V801 Arae, the optical companion to the neutron star in 4U 1636-53. We show that a range of circular orbits with velocity 90 < v sin i < 175 km/s and fractional phase 0.336 > p > 0.277 for the neutron star can provide an excellent description of the frequency and phase evolution. The average pulse profile is sinusoidal and the time averaged pulsation amplitude, as inferred from the half amplitude of the sinusoid is 1%, smaller than typical for burst oscillations observed in normal thermonuclear bursts. We do not detect any higher harmonics nor the putative subharmonic near 290 Hz. The 90% upper limits on signal amplitude at the subharmonic and first harmonic are 0.1% and 0.06%, respectively. The coherent pulsation provides compelling evidence for a rapidly rotating neutron star in 4U 1636-53, and further supports the connection of burst oscillation frequencies with the spin frequencies of neutron stars. Our results provide further evidence that some millisecond pulsars are spun up via accretion in LMXBs. We also discuss the implications of our orbital velocity constraint for the masses of the components of 4U 1636-53.

description: One enduring challenge for controlling high frequency sound in local active noise control (ANC) systems is to obtain the acoustic signal at the specific location to be controlled. In some applications such as in ANC headrest systems, it is not practical to install error microphones in a person's ears to provide the user a quiet or optimally acoustically controlled environment. Many virtual error sensing approaches have been proposed to estimate the acoustic signal remotely with the current state-of-the-art method using an array of four microphones and a head tracking system to yield sound reduction up to 1 kHz for a single sound source. In the work reported in this paper, a novel approach of incorporating remote acoustic sensing using a laser Doppler vibrometer into an ANC headrest system is investigated. In this 'virtual ANC headphone' system, a lightweight retro-reflective membrane pick-up is mounted in each synthetic ear of a head and torso simulator to determine the sound in the ear in real-time with minimal invasiveness. The membrane design and the effects of its location on the system performance are explored, the noise spectra in the ears without and with ANC for a variety of relevant primary sound fields are reported, and the performance of the system during head movements is demonstrated. The test results show that at least 10 dB sound attenuation can be realised in the ears over an extended frequency range from (500 Hz to 6 kHz) under a complex sound field and for several common types of synthesised environmental noise, even in the presence of head motion.

description: We investigate how production process labels and information about potential positive and/or negative aspects of GM technology affects demand for novel seafood products. We collected data during an online choice experiment distributed among 1,043 United States seafood consumers. Our results indicate participants not provided with GM information are willing to pay a premium for Verified Non-GM and Organic fillets, but require a discount for Fed-GM and GM fillets. Positive information reduces willingness to pay (WTP) for Organic, Non-GM and GM fillets, while negative information significantly increases WTP for Organic fillets and reduces WTP for GM fillets. Balanced information reduces WTP for Organic and Verified Non-GM salmon, similar in magnitude to positive information, and reduces WTP for GM-Fed and GM salmon, similar in magnitude to negative information. We provide some recommendations and discussion on how producers and food sellers might encourage effective communication between themselves and consumers based on our findings and the broader literature.

 Diagnosis. Rostrum semi-oval, armed anteriorly with small, sharp teeth; upper surface granulate, slightly concave. Carapace lightly pubescent, with 7 sharp longitudinal ridges. Orbit semicircular, outer orbital angle small, blunt. Antennular peduncle longer than rostrum. Scaphocerite with 7–8 sharp teeth on outer margin, shorter than third segment of antennular peduncle. Ischium of third maxilliped armed on inner side with row of spinules, merus with distal tooth, propodus, dactyl subequal in length, longer than carpus. Pereopod 1 subchelate, propodus broad, upper margin carinate, with large fixed tooth, 3–4 smaller teeth on inner margin. Pereopod 2 short, stout; long setae on merus, simple, setose dactyl. Pereopods 3, 4 more slender, longer than second, with few setae; simple, slender dactyls. Abdominal somites without carinae or teeth. Telson rounded, sides with very fine teeth, 3 pairs lateral spines. Exopod of uropod shorter than endopod, both divided by sutures across posterior half. Carapace length to 7.7 mm, total length 19.2 mm.
 Color in life. Bright orange, with appendages speckled with white or beige, dorsal surface of abdomen more uniform beige or cream (Sirota & Martin 2005).
 Habitat. Under rocks in pool, among eelgrass (Zostera sp.), sand flats; intertidal zone to 11.2 m.
 Range. Newport Bay and La Jolla, California; Ensenada de San Francisco, Sonora, Gulf of California, Mexico to Wafer Bay, Cocos I., Costa Rica. Type locality La Jolla, California.
 Remarks. This peculiar animal was originally thought to be a sand shrimp (Caridea: Crangonidae). The similarity in the subchelate first pereopods could be confusing. The sutures of the uropod, the unusual rostrum and the ridges of the carapace are characteristic.

description: This paper examines the level of export earnings instabilities of ACP countries (African, Caribbean and pacific states signatories of the Lome Convention); their evolution through time and across countries. At present, this group comprises of seventy developing countries. This deliberate choice of the sample was done in order to examine whether fluctuations in export earnings of these countries have relatively decreased as envisaged by the STABEX system, of the lome Convention introduced in 1975 by the European Economic Community. The country coverage of previous studies on export earnings instabilities was generally limited and most of the ACP countries over the periods 1970-1979, 1980-1990 and 1970-1990. The results of the study indicate that instability indices very across countries. Moreover, a comparison of the indices for 1970-1979 and 980-1990 reveals that for more than half of the countries in the sample(21) , there was a reduction on the level of export instability between the two periods whereas for fifteen countries the reverse was true. It was only for three countries that instability indicates remained the same between 1970s and 1980s.

description: We present a new model to explain the excess in mid and near infrared emission of the central, hydrogen poor dust knot in the planetary nebula (PN) Abell 58. Current models disagree with ISO measurement because they apply an average grain size and equilibrium conditions only. We investigate grain size distributions and temperature fluctuations affecting infrared emission using a new radiative transfer code and discuss in detail the conditions requiring an extension of the classical description. The peculiar infrared emission of V605 Aql, the central dust knot in Abell 58, has been modeled with our code. V605 Aql is of special interest as it is one of only three stars ever observed to move from the evolutionary track of a central PN star back to the post-AGB state.

description: The North Wyke Farm Platform (NWFP) was established in 2010 to study and improve grassland livestock production at the farm-scale. The NWFP uses a combination of environmental sensors, routine field and lab-based measurements, and detailed management records to monitor livestock and crop production, emissions to water, emissions to air, soil health, and biodiversity. The rich NWFP datasets help researchers to evaluate the effectiveness of different grassland (and arable) farming systems, which in turn, contributes to the development of sustainable, resilient and net zero land management strategies. This document serves as a user guide to the forage (pasture, silage) quantity and quality data and is associated with other dedicated user guides that detail the collection, and quality control processing of all the datasets produced on the NWFP.

description: To examine the longitudinal behavior of refractive errors in both retinopathy of prematurity (ROP) and non-ROP screened premature children during the first three years of life. This retrospective cohort included premature children (less than 37 weeks gestational age) born between 10/2011 and 8/2013 with ≥ two cycloplegic refractions. Cycloplegic refractions were converted into power vectors: M (spherical equivalent), J0 [positive for with-the-rule (WTR) and negative for against-the-rule (ATR) astigmatism], and J45 (oblique astigmatism). Each power vector component was fitted by multilevel mixed-effects linear regression models; the mean change over time was analyzed. Mean J0 was 0.59 (95% CI 0.53–0.66) at six months and 0.29 (95% CI 0.19–0.39) at 18 months; afterward, the change was <0.1 per year. J0 decreased −0.32 (0.64 diopters) over three years. When analyzed in one-year increments, the mean change in J0 and M was lowest at 24 months. M decreased 1.13 diopters over three years. WTR astigmatism and spherical equivalent decreased over the first three years of life. WTR astigmatism accounted for the majority of amblyopogenic refractive errors. The change in J0 leveled after 18 months and the lowest rate of change was at 24 months in J0 and M, thus it may be appropriate to screen this high-risk population around 18–24 months.

description: Slow-fast dynamics and resonant phenomena can be found in a wide range of physical systems, including problems of celestial mechanics, fluid mechanics, and charged particle dynamics. Important resonant effects that control transport in the phase space in such systems are resonant scatterings and trappings. For systems with weak diffusive scatterings the transport properties can be described with the Chirikov standard map, and the map parameters control the transition between stochastic and regular dynamics. In this paper we put forward the map for resonant systems with strong scatterings that result in non-diffusive drift in the phase space, and trappings that produce fast jumps in the phase space. We demonstrate that this map describes the transition between stochastic and regular dynamics and find the critical parameter values for this transition.

description: In this work, the electrical properties of Al2O3 films deposited by reactive ion sputtering were investigated by means of morphological, chemical and electrical characterizations. This insulating layer suffers of an electron trapping that is mitigated after the rapid thermal annealing (RTA). The RTA improved also the permittivity (up to 6ε0), although the negative fixed charge remains in the order of 1012cm-2. However, the temperature dependent electrical investigation of the MOS capacitors demonstrates that the room temperature Fowler-Nordheim electron barrier height of 2.37 eV lies between the values expected for SiO2/4H-SiC and Al2O3/4H-SiC systems.

description: We study the dynamics of genetic code evolution. The model of Vetsigian et al. [1] and Vetsigian [2] uses the mechanism of horizontal gene transfer to demonstrate convergence of the genetic code to a near universal solution. We reproduce and analyze the algorithm as a dynamical system. All the parameters used in the model are varied to assess their impact on convergence and optimality score. We show that by allowing specific parameters to vary with time, the solution exhibits attractor dynamics. Finally, we study automorphisms of the genetic code arising due to this model. We use this to examine the scaling of the solutions in order to re-examine universality and find that there is a direct link to mutation rate.

description: The chromatin fiber is a complex of DNA and specific proteins called histones forming the first structural level of organization of eukaryotic chromosomes. In tightly organized chromatin fibers, the short segments of naked DNA linking the nucleosomes are strongly end constrained. Longitudinal thermal fluctuations in these linkers allow intercalative mode of protein binding. We show that mechanical constraints generated in the first stage of the binding process induce linker DNA buckling; buckling in turn modifies the binding energies and activation barriers and creates a force of decondensation at the chromatin fiber level. The unique structure and properties of DNA thus yield a novel physical mechanism of buckling instability that might play a key role in the regulation of gene expression.

description: In late 1970s and through 1980s, state control in agricultural marketing was taken as the best for the development of peasant agriculture. Later however, state failure was claimed and the need for market oriented strategy has been advocated. Both had their own impact on peasant producers. This paper discuses their impact on the peasantry. It is found that it should not be a question of statist or markets substituting each other but should operate in a complementary way to improve the agricultural marketing system and enhance peasant agriculture.

description: We have detected the neutral atomic hydrogen (HI) emission line at a cosmologically significant distance (z=0.18) in the rich galaxy cluster Abell 2218 with the Westerbork Synthesis Radio Telescope. The HI emission originates in a spiral galaxy 2.0 megaparsecs from the cluster core. No other significant detections have been made in the cluster, suggesting that the mechanisms that remove neutral gas from cluster galaxies are efficient. We infer that fewer than three gas-rich galaxies were accreted by Abell 2218 over the past 10^9 years. This low accretion rate is qualitatively consistent with low-density cosmological models in which clusters are largely assembled at z>1.

description: We present results on the thermal and kinetic Sunyaev-Zel'dovich (SZ) effects from a sequence of high resolution hydrodynamic simulations of structure formation, including cooling, feedback and metal injection. These simulations represent a self-consistent thermal model which incorporates ideas from the `pre-heating' scenario while preserving good agreement with the low density IGM at z~3 probed by the Ly-a forest. Four simulations were performed, at two different resolutions with and without radiative effects and star formation. The long-wavelength modes in each simulation were the same, so that we can compare the results on an object by object basis. We demonstrate that our simulations are converged to the sub-arcminute level. The effect of the additional physics is to suppress the mean Comptonization parameter by 20% and to suppress the angular power spectrum of fluctuations by just under a factor of two in this model while leaving the source counts and properties relatively unchanged. We quantify how non-Gaussianity in the SZ maps increases the sample variance over the standard result for Gaussian fluctuations. We identify a large scatter in the Y-M relation which will be important in searches for clusters using the SZ effect(s).

title: Exploring the Role of Virtual Reality in Retail
Creators: name: Zhang, Yunen
Publisher: name: Griffith University

Subjects: subject: decision-making
subject: virtual reality (VR) retail
subject: cognitive process
subject: boundary conditions

description: Purpose: This thesis investigates the effectiveness of virtual reality (VR) retail environments in shaping consumer cognitive processes and decision-making. Design/Methodology/Approach: A series of experimental studies were conducted. Study 1 examines VR's overall effectiveness compared to traditional media in enhancing mental imagery and purchase intention. Study 2 investigates how VR immersion influence consumer purchase decisions via facilitated product diagnosticity and enhanced psychological closeness. Study 3 explores the role of fantastical store designs in promoting cognitive flexibility and divergent choices. Individual-related attributes, product-related attributes, and VR interface-related attributes were considered as boundary conditions across three studies. Findings: Compared to traditional media, VR enhances mental imagery and purchase intention, particularly for consumers with low product knowledge, with experiential shopping orientation and high product involvement mitigating the negative impact of high product knowledge. Immersive VR does not outperform non-immersive VR in facilitating product diagnosticity, psychological closeness, and purchase intention under the high product interactivity condition, while product graspability and haptic information improve the effectiveness of immersive VR. Compared to realistic VR store designs, fantastical designs promote cognitive flexibility and divergent choices when digital avatars are presented in the virtual store. Research Limitations/Implications: This thesis contributes to the theoretical understanding of VR by examining its effectiveness across different dimensions, including overall effectiveness compared to traditional media, the impact of varying levels of immersion, and the influence of virtual environmental design. It offers valuable practical contributions for retailers seeking to leverage VR technology to enhance consumer cognitive evaluations and acquire tangible benefits. Originality/Value: This thesis provides a novel contribution to VR retail literature by systematically examining the overall, technological, and environmental attributes of VR technology. It also goes beyond prior research by uncovering how VR influences deeper cognitive processes and decision-making. The research also introduces new perspectives on boundary conditions, offering a more nuanced understanding of the effectiveness of VR retail.
Using Correlation Integrals to Characterize 3D Stellar Orbits

description: In an effort to more fully understand the variety of stellar distribution functions that can be used to construct models of realistic galaxies, the correlation integral method for orbit characterization that previously has been introduced by Grassberger & Procaccia (1983) and Carnevali & Santangelo (1984) is examined in considerable detail. The broad utility of the method is validated and demonstrated by applying it to orbits in a number of different, previously studied test cases (1D, 2D, and 3D; nonrotating and rotating). At the same time, the correlation integral method is compared and contrasted with other more traditional characterization tools such as Lyapunov exponents and surfaces of section. The method is then extended to orbits in a previously unexamined rotating, 3D bar potential. The correlation integral method is found to be a simple and reliable way to quantitatively categorize orbits in virtually any potential. It is recommended that it be broadly adopted as a tool for characterizing the properties of orbits and, by extension, stellar distribution functions, in all Hamiltonian dynamical systems.

description: The literature of commodity supply functions is characterized by explanatory variables which are either current or lagged (relative) prices. This study not only underlines the existence of other factors but also emphasizes their explicit incorporation in estimation. By using pooled data of African countries, first, price focused estimations are explored. Subsequently estimation using other relevant shows that(a) there is a clear difference between UNCTAD’S world prices and the regional price constructed for Africa, hence previous studies using the former could have based elastic ties(b) real exchange rat has statistically significant elasticity with clear long and short run distinction, this underscores the relevance of the Error Correction Model (ECM) (c) capital formation indicators are also found to have positive elastic ties, (d) there is a variation across regions and (e) estimation with foreign inflow included gives variation across regions and(e) estimation with foreign inflow included gives a mixed result.

description: High-Tc copper oxides of the LSCO family show a very clear case of competition between antiferromagnetic (AF) order and superconductivity. Magnetic order can, however, coexist with superconductivity, and the experimental evidence for frozen magnetic moments in superconducting samples is reviewed here. The primary characteristics of the magnetic order are summarized and some open questions are outlined, particularly concerning the intrinsic or extrinsic nature of this order around x=0.12.

description: A new denoising algorithm for hyperspectral complex domain data has been developed and studied. This algorithm is based on the complex domain block-matching 3D filter including the 3D Wiener filtering stage. The developed algorithm is applied and tuned to work in the singular value decomposition (SVD) eigenspace of reduced dimension. The accuracy and quantitative advantage of the new algorithm are demonstrated in simulation tests and in the processing of the experimental data. It is shown that the algorithm is effective and provides reliable results even for highly noisy data.

description: IEEE 802.11 networks have a great role to play in supporting and deploying of the Internet of Things (IoT). The realization of IoT depends on the ability of the network to handle a massive number of stations and transmissions, and to support Quality of Service (QoS). IEEE 802.11 networks enable the QoS by applying the Enhanced Distributed Channel Access (EDCA) with static parameters regardless of existing network capacity or which Access Category (AC) of QoS is already active. Our objective in this paper is to improve the efficiency of the uplink access in 802.11 networks; therefore we proposed an algorithm called QoS Categories Activeness-Aware Adaptive EDCA Algorithm (QCAAAE) which adapts Contention Window (CW) size, and Arbitration Inter-Frame Space Number (AIFSN) values depending on the number of associated Stations (STAs) and considering the presence of each AC. For different traffic scenarios, the simulation results confirm the outperformance of the proposed algorithm in terms of throughput (increased on average 23%) and retransmission attempts rate (decreased on average 47%) considering acceptable delay for sensitive delay services.

description: Background: Maternal colonization with group B Streptococcus (GBS) is a predictor of neonatal sepsis. In Nicaragua, neonatal sepsis is a major cause of hospitalization, but it can be prevented with intrapartum antibiotic prophylaxis. We undertook this study to estimate the pooled prevalence of rectovaginal GBS colonization among pregnant women 35–40-week gestation in Nicaragua, and sensitivity of GBS isolates to various antibiotics. Methods: We systematically searched electronic databases of peer-reviewed and unpublished literature using prespecified search terms. We included English- and Spanish-language studies of rectovaginal GBS colonization and/or antibiotic sensitivity of GBS isolates that followed internationally-recognized diagnostic standards, from various sites and years. Two reviewers independently abstracted data and assessed risk of study bias. We then meta-analyzed the pooled prevalence of rectovaginal GBS colonization and antibiotic sensitivity of GBS isolates. We performed subgroup analyses by geographic location, urbanicity, and study risk of bias. Main results: Prevalence of rectovaginal GBS colonization from 13 samples in 11 studies was 0.14 (95% CI: 0.09, 0.21). Effect size heterogeneity was identified between coastal (0.12 [95% CI: 0.07, 0.19]) and central study sites (0.23 [95% CI: 0.18, 0.28]), and between predominantly rural (0.06 [95% CI: 0.02, 0.10]) and urban (0.28 [95% CI: 0.19, 0.37]) samples of pregnant women. GBS sensitivity to penicillin, the first-line antibiotic for intrapartum prophylaxis, was 0.89 (95% CI: 0.71, 1.00) based on seven studies. Conclusions: Maternal GBS colonization was substantial in some study sites. Most GBS isolates are sensitive to recommended antibiotics, and intrapartum antibiotic prophylaxis may effectively prevent neonatal sepsis in Nicaragua.
