description: In this paper, we study anisotropic spheres built from known static spherical solutions. In particular, we are interested in the physical consequences of a "small" departure from a physically sensible configuration. The obtained solutions smoothly depend on free parameters. By setting these parameters to zero, the starting seed solution is regained. We apply our procedure in detail by taking as seed solutions the Florides metrics, and the Tolman IV solution. We show that the chosen Tolman IV, and also Heint IIa Durg IV,V perfect fluid solutions, can be used to generate a class of parametric solutions where the anisotropic factor has features recalling boson stars. This is an indication that boson stars could emerge by "perturbing" appropriately a perfect fluid solution (at least for the seed metrics considered). Finally, starting with Tolman IV, Heint IIa and Durg IV,V solutions, we build anisotropic gravastar-like sources with the appropriate boundary conditions.

description: Here we view naturalness from the point of view of proximate behavioural control. The mechanisms of behaviour control have evolved in order that animals reach a specific goal after they have performed motivated behaviour. This goal was closely related to a function at the time when the mechanism evolved. Function and goal may be de-coupled in a novel environment such as artificial housing conditions. We argue that an animal that can perform the behaviour it wants and can reach the goals it likes can behave according to what is “in-its-nature” even under human influenced conditions. We illustrate this argument using abnormal sucking behaviour in calves and piglets as well as dehorning in cattle and goats. We conclude that a minimal welfare standard is ensured for animals that are given the opportunity to behave as is in-their-nature.
Community process modelling and rural community development
Creators: name: Percey, H

description: Community development (CD) has been demonstrated to effectively deliver sought-after benefits towards improved economic, social, physical and psychological wellbeing. CD in rural areas is thus an important response to the change pressures in rural communities. Millions of dollars are spent annually on rural community development (RCD) activities. Yet CD is complex with many interacting variables and these dynamic processes are particularly visible in rural communities. RCD can have unintended (positive and negative) consequences upon the interwoven dynamics of the fabric of rural communities, independent of whether or not project objectives are achieved. A greater theoretical understanding of these processes is needed to better manage RCD outcomes and side effects. Such theoretical understanding is currently lacking in CD literature. The purpose of this study was to use a grounded theory approach to generate a theoretical understanding of how RCD implementation processes interact with and affect the fabric of a community. Open interviews with twenty participants across three different RCD projects and rural sites were the key data source, contextualised by observation and written documentation. Based on differing aetiologies, the study identified three types of community associated with and including the rural community: feature, interest and cause based. It was found that a multiplicity of these communities acted as constituents of each rural community, being part of, yet separate to the rural community. In coexisting, they were constituted by and subject to boundary processes. Literature describes such boundary processes in terms of differentiation and symbolic expression. This study identified additional processes of agendas, alignment and non-alignment. RCD involved establishing and managing a further cause based constituent community amongst existing constituent communities and within the rural community. RCD projects were subject to boundary processes in creating their community identity, as well as in their interaction with other communities whilst pursuing project objectives. The study found that the often conflated concepts of community ownership and support were also distinct processes with different roles in RCD. How all these processes were managed affected both the rural community fabric and the success of projects. The thesis develops a theoretical model which will contribute to understanding and managing community processes and RCD for theorists and practitioners alike. Due to sample limitations, further research is needed to establish the extent to which the model can be extrapolated to other settings.

A study of the antibody response to antigenic preparations derived from Pseudomonas aeruginosa
Creators: name: Johnston, Linda Joan
Publisher: name: University of British Columbia
Year: 2011

description: Several cellular and subcellular fractions were prepared from Pseudomonas aeruginosa strain PA-7. Those found to be immunogenic in rabbits included a heat-stable lipopolysaccharide, a protein-lipopolysaccharide complex, a cell wall preparation arid a formalin-killed whole cell vaccine. However, a lipopolysaccharide preparation extracted with phenol and water was found to be a poor immunogen in rabbits. The cell wall fraction proved to be the most effective immunogen in terms of the amount of antibody evoked, and of the duration of the serum antibody response. Hyperimmune sera produced against all four antigens were found to contain a mixed population of 2-mercaptoethanol sensitive and 2-mercaptdethanol resistant antibodies. Gel filtration and ion exchange chromatography studies established the presence of both IgM and IgG immunoglobulins in all four types of hyperimmune serum. Whole immune serum, as well as the IgM and IgG serum fractions, afforded passive protection to mice challenged with twenty or more LD₅₀ of viable organisms. There was an indication that the IgG fraction of two of the four serum types provided better protection than did the IgM fraction, but precipitation studies indicated that this may have been due to greater numbers of IgG immunoglobulins. In addition serum containing a high proportion of 2-mercaptoethanol resistant antibody-was found to promote faster clearance of injected bacteria than did serum taken earlier in the response. Immunodiffusion studies indicated that all four antigenic preparations contained at least one common immunogen; moreover, all serum types were able to react with sheep red blood cells coated with the heat-stable lipopolysaccharide preparation in passive hemagglutination and hemolysin tests.

description: The effect of atomic disorder induced by neutrons irradiation on superconducting and normal state properties of polycrystalline LaFeAsO_0.9F_0.1 was investigated. The irradiation of the sample by a moderate neutron fluence F = 1.6*1019 cm^-2 at Tirr = 50 +- 10 C leads to the suppression of superconductivity which recovers almost completely after annealing at temperatures Tann < 750 C. It is shown that the reduction of superconducting transition temperature Tc under atomic disordering is not determined solely by the value of Hall concentration nH, i.e. doping level, but is governed by the reduction of electronic relaxation time. This behavior can be described qualitatively by universal Abrikosov-Gorkov equation which presents evidence on the anomalous type of electrons pairing in Fe-based superconductors.

description: High-precision measurements of the scattering observables such as cross sections and analyzing powers for the proton-deuteron elastic and break-up reactions have been performed at KVI in the last two decades and elsewhere to investigate various aspects of the three-nucleon force (3NF) effects simultaneously. In 2006 an experiment was performed to study these effects in $\vec{p}+d$ break-up reaction at 135 MeV with the detection system, Big Instrument for Nuclear polarization Analysis, BINA. BINA covers almost the entire kinematical phase space of the break-up reaction. The results are interpreted with the help of state-of-the-art Faddeev calculations and are partly presented in this contribution.

description: The spatial distributions of the most recently discovered ultra faint dwarf satellites around the Milky Way and the Andromeda galaxy are compared to the previously reported discs-of-satellites (DoS) of their host galaxies. In our investigation we pay special attention to the selection bias introduced due to the limited sky coverage of SDSS. We find that the new Milky Way satellite galaxies follow closely the DoS defined by the more luminous dwarfs, thereby further emphasizing the statistical significance of this feature in the Galactic halo. We also notice a deficit of satellite galaxies with Galactocentric distances larger than 100 kpc that are away from the disc-of-satellites of the Milky Way. In the case of Andromeda, we obtain similar results, naturally complementing our previous finding and strengthening the notion that the discs-of-satellites are optical manifestations of a phase-space correlation of satellite galaxies.

Estimating the radiation environment in the Great Barrier Reef
Creators: name: Masiri, IO
Publisher: name: University Of Tasmania
Year: 2023

description: There are a number of studies that have examined solar irradiance in the environment above and below the ocean surface. Unlike other previous studies, this thesis maps both surface and underwater irradiances using a combination of geostationary and Sea WiFS satellite data and surface measurements. Detailed estimates of broadband, PAR and UVB solar radiation, both above and below water, is obtained for the Great Barrier Reef region in northeast Australia. The study area covers the Coral Sea including the Great Barrier Reef (GBR), northeast of Queensland (10¬¨‚àû S - 26¬¨‚àû S, 142¬¨‚àû E - 155¬¨‚àû E). Geostationary meteorological satellite (GMS) data collected for periods between 1995 and 2005 are combined with the models to obtain broadband solar radiation at the surface. PAR and UVB underwater irradiance are estimated from the attenuation coefficients K\\(_d\\) derived from the Sea WiFS instrument for the period of 1998-2005. In developing algorithms, a look-up table (LUT), which contains senes of broadband surface solar radiation and the Earth-atmosphere reflectivity, is created from the Streamer radiative transfer model. The broadband Earth-atmosphere reflectivity ˜í¬±\\(_{EA}\\) derived from the GMS data is used to estimate the surface solar radiation from the LUT algorithms. The attenuation coefficients K\\(_d\\) for PAR, UVB and Sea WiFS wavebands are obtained from Monte Carlo models, and relationships between these Kd values are derived as a result. Using Sea WiFS-derived K\\(_d\\) data, PAR and UVB underwater irradiance are estimated across the regions from the K\\(_d\\) relationships. Comparisons between the satellite-derived surface solar radiation and the measurements at Rockhampton and Cairns give good agreement with root-mean-square difference (RMSD) of 2.26 MJ-m\\(^{-2}\\)-day\\(^{-1}\\) and 2.85 MJ-m\\(^{-2}\\)-day\\(^{-1}\\) , respectively. The Sea WiFS-derived K\\(_d\\) at six different wavebands obtained from Monte Carlo models are compared to the measurements at Heron Island, with a smallest RMSD value of 0.075m\\(^{-1}\\). Maps of solar radiation both above and below the water surface are provided for the study area. On average, strong solar radiation is exhibited in summer and autumn periods at latitude bands between 18¬¨‚àû S and 26¬¨‚àû S. The temporal information suggests there is a small increase in solar radiation of about 1 percent per decade. The underwater PAR and UVB irradiances along the GBR coastline at 2.5 m depth were in magnitude of ~300 W-m\\(^{-2}\\) and ~120 mW-m\\(^{-2}\\), respectively. Monthly distribution at 2.5 m depth underwater for PAR shows an outstanding feature throughout between September and February. There are patterns of high PAR irradiance throughout the summer months of 2001/2002 and 2002/2003. Results of the satellite-derived solar radiation are used to examine the 2002 coral bleaching events. A correlation between maximum solar radiation and the bleaching data are seen in summer months of 2001/2002.

description: We consider a gravitational theory of a scalar field $ϕ$ with nonminimal derivative coupling to curvature. The coupling terms have the form $κ_1 Rϕ_{,μ}ϕ^{,μ}$ and $κ_2 R_{μν}ϕ^{,μ}ϕ^{,ν}$ where $κ_1$ and $κ_2$ are coupling parameters with dimensions of length-squared. In general, field equations of the theory contain third derivatives of $g_{μν}$ and $ϕ$. However, in the case $-2κ_1=κ_2\equivκ$ the derivative coupling term reads $κG_{μν}ϕ^{,mu}ϕ^{,ν}$ and the order of corresponding field equations is reduced up to second one. Assuming $-2κ_1=κ_2$, we study the spatially-flat Friedman-Robertson-Walker model with a scale factor $a(t)$ and find new exact cosmological solutions. It is shown that properties of the model at early stages crucially depends on the sign of $κ$. For negative $κ$ the model has an initial cosmological singularity, i.e. $a(t)\sim (t-t_i)^{2/3}$ in the limit $t\to t_i$; and for positive $κ$ the universe at early stages has the quasi-de Sitter behavior, i.e. $a(t)\sim e^{Ht}$ in the limit $t\to-\infty$, where $H=(3\sqrtκ)^{-1}$. The corresponding scalar field $ϕ$ is exponentially growing at $t\to-\infty$, i.e. $ϕ(t)\sim e^{-t/\sqrtκ}$. At late stages the universe evolution does not depend on $κ$ at all; namely, for any $κ$ one has $a(t)\sim t^{1/3}$ at $t\to\infty$. Summarizing, we conclude that a cosmological model with nonminimal derivative coupling of the form $κG_{μν}ϕ^{,mu}ϕ^{,ν}$ is able to explain in a unique manner both a quasi-de Sitter phase and an exit from it without any fine-tuned potential.

Valuation theory and real property assessment
Creators: name: Rollo, Gordon Paul
Publisher: name: University of British Columbia
Year: 2011

description: The real property tax has a major impact on real property owners in all Canadian municipalities. As with all systems of taxation it is important that the burden of this tax be distributed fairly and equitably. Legislators have attempted to ensure equitable treatment among real property owners by requiring that the basis of assessment should be 'actual value'. However, due to the large numbers of properties to be valued, assessors have not been able to use the market approach to value, a valuation technique known to produce 'actual values'. Rather, they have resorted to the more subjective cost approach to value. While the mechanics of the cost approach lend themselves to the mass valuation problem, they rarely produce values that can be equated with actual market values. The application of multiple regression analysis is presented as a solution to this valuation problem. Multiple regression analysis enables the assessor to produce objectively the 'actual value' of all single family homes in a municipality. After presenting multiple regression analysis as a modern application of the market approach to value, the applicability of this valuation technique is tested on actual sales data. A sample of approximately four hundred recently sold single family homes is subjected to valuation by multiple regression analysis. Various experiments, including means of stratifying the data are presented in an attempt to produce high standards of solution. While the statistical results of the experiment are not of sufficient calibre for practical assessment purposes, they do reveal how continued experimentation can improve the applicability of this valuation technique to mass appraisal. Multiple regression analysis is the assessor's tool of the future. It facilitates the application of a valuation technique that will permit the assessor to meet his statutory obligation while still allowing him to adhere to sound appraisal methodology.
Electron spin resonance and optical studies of doped copper (II) Tetrahedral complexes
Creators: name: Cashion, SP
Publisher: name: University Of Tasmania
Year: 2023

description: This report presents an investigation of a pseudotetrahedral bromocuprate (II) compound. The bromocuprates exhibit a great structural diversity, however, the comparatively rare compressed tetrahedral compounds have been somewhat neglected. The determination of the electronic and geometric structure of these compounds has implications in the analysis of active sites in copper blue proteins. Electron Spin Resonance (E.S.R.) and optical spectra have been measured at low temperature, for single crystals of copper (II) doped into bis( ethylenediammoniummonobromide) tetrabromozincate (II), ( enH.HBr)2 ZnBr4. The room temperature powder reflectance spectrum has also been measured for this compound, along with that of the pure zinc analogue. The transition energies derived from the electronic spectra have been assigned and compared to the respective transitions based on previous studies. With the aid of a computer program, a set of theoretical transition energies has been calculated utilizing the Angular Overlap Model. Adjusting these to fit the observed values confirms the presence of a distorted tetrahedral geometry for the guest ion. At 77K, the E.S.R. spectrum of (enH2)2Zn[Cu]Br6 exhibits well resolved copper hyperfine and bromine superhyperfine couplings. Computer simulation techniques have produced optimum values for these parameters, which suggest that the principal z-axis of the superhyperfine tensor does not coincide with the copper-bromine bond direction. The bonding in the guest [CuBr4]2- ion has been described in terms of the relative unpaired electron density within the bromine 4s and 4p orbitals, which shows an increased covalency when compared with the chlorine counterpart. A highly rhombic g tensor results in an unusual groundstate. The calculated mixing coefficients and corresponding wavefunction parameters show that the dz2 orbital makes a small but significant contribution by mixing with the pure dx2-y2 orbital.

description: This paper tackles important aspects of comets dynamics from a statistical point of view. Existing methodology uses numerical integration for computing planetary perturbations for simulating such dynamics. This operation is highly computational. It is reasonable to wonder whenever statistical simulation of the perturbations can be much more easy to handle. The first step for answering such a question is to provide a statistical study of these perturbations in order to catch their main features. The statistical tools used are order statistics and heavy tail distributions. The study carried out indicated a general pattern exhibited by the perturbations around the orbits of the important planet. These characteristics were validated through statistical testing and a theoretical study based on Opik theory.

description: We compare the amount of magnetic flux measured in Stokes V and Stokes I in a sample of early- and mid-M stars around the boundary to full convection (~M3.5). Early-M stars possess a radiative core, mid-M stars are fully convective. While Stokes V is sensitive to the net polarity of magnetic flux arising mainly from large-scale configurations, Stokes I measurements can see the total mean flux. We find that in early-M dwarfs, only ~6% of the total magnetic flux is detected in Stokes V. This ratio is more than twice as large, ~14%, in fully convective mid-M dwarfs. The bulk of the magnetic flux on M-dwarfs is not seen in Stokes V. This is presumably because magnetic flux is mainly stored in small scale components. There is also more to learn about the effect of the weak-field approximation on the accuracy of strong field detections. In our limited sample, we see evidence for a change in magnetic topology at the boundary to full convection. Fully convective stars store a 2-3 times higher fraction of their flux in fields visible to Stokes V. We estimate the total magnetic energy detected in Stokes I and compare it to results from Stokes V. We find that in early-M dwarfs only ~0.5% of the total magnetic energy is detected in Stokes V while this fraction is ~2.5% in mid-M dwarfs.

Views and attitudes of staff and students towards the significance of intercultural awareness in foreign language teaching and learning in an Australian university context
Creators: name: Wang, YanJun
Publisher: name: University Of Tasmania
Year: 2023

description: Globalisation is influencing foreign language education at universities worldwide. People now live in an increasingly multicultural world where different cultural practices have blended. Thus, intercultural awareness has now become a vital part of foreign language learning. The aim of the study was to investigate teachers' and students' beliefs and understandings of the significance of intercultural awareness in foreign language teaching and learning in a university context. As the study was situated within the Tasmanian context, it sought to provide contextual information and implications meaningful and appropriate to the local language learning environment. The investigation focused on three areas: generalising the participants' perceptions of the importance of intercultural awareness in general; examining their intercultural experiences, personally and professionally, especially in relation to language teaching and learning; and identifying the factors that influenced the way they teach and learn. The study employed both quantitative and qualitative research approaches for data collection and analysis. It included two phases: questionnaire survey and subsequent interview. The statistical data were analysed using the SPSS (Statistical Package for the Social Science) software version 20.0. The textual data collected from the interviews were analysed using the NVivo qualitative data software version 10.0. Thematic analysis was used in the qualitative data analysis. The results of this study indicated strong recognition of the key role that intercultural awareness plays in foreign language teaching and learning. Based on the findings, pedagogical implications and directions for further research were also addressed. The findings suggested that language learners should cultivate intercultural awareness in the process of their language learning as it is considered the major goal of foreign language learning. Meanwhile, teachers' intercultural awareness could influence their language teaching methodology and course design. A paradigm shift from a traditional to an intercultural stance in language education poses a challenge for both language teachers and students if they wish to meet the goals of foreign language education for the global context.

description: We investigate the role of lattice polarization in determination of induced carrier density at the $n$-type interface of LaAlO$_3$ overlayer on SrTiO$_3$ (001) by carrying out density-functional-theory calculations. When no oxygen vacancy or defect is present, the magnitude of polarization screening in the LaAlO$_3$ layers is found to be correlated with the carrier charge induced at the interface. For the interfaces with a few LaAlO$_3$ layers, the induced charge carrier is compensated by the electrostatic screening and consequently its density remains far less than 0.5 electrons per unit cell.

description: We study the kinetics of the liquid-to-crystal transformation and of gel formation in colloidal suspensions of oppositely charged particles. We analyse, by means of both computer simulations and experiments, the evolution of a fluid quenched to a state point of the phase diagram where the most stable state is either a homogeneous crystalline solid or a solid phase in contact with a dilute gas. On the one hand, at high temperatures and high packing fractions, close to an ordered-solid/disordered-solid coexistence line, we find that the fluid-to-crystal pathway does not follow the minimum free energy route. On the other hand, a quench to a state point far from the ordered-crystal/disordered-crystal coexistence border is followed by a fluid-to-solid transition through the minimum free energy pathway. At low temperatures and packing fractions we observe that the system undergoes a gas-liquid spinodal decomposition that, at some point, arrests giving rise to a gel-like structure. Both our simulations and experiments suggest that increasing the interaction range favors crystallization over vitrification in gel-like structures.

description: The field of Materials Science is concerned with, e.g., properties and performance of materials. An important class of materials are crystalline materials that usually contain “dislocations” – a line-like defect type. Dislocation decisively determine many important materials properties. Over the past decades, significant effort was put into understanding dislocation behavior across different length scales both with experimental characterization techniques as well as with simulations. However, for describing such dislocation structures there is still a lack of a common standard to represent and to connect dislocation domain knowledge across different but related communities. An ontology offers a common foundation to enable knowledge representation and data interoperability, which are important components to establish a “digital twin”. This paper outlines the first steps towards the design of an ontology in the dislocation domain and shows a connection with the already existing ontologies in the materials science and engineering domain.
On the number of young stellar discs in the Galactic Centre

description: Observations of the Galactic Centre show evidence of disc-like structures of very young stars orbiting the central super-massive black hole within a distance of a few 0.1 pc. While it is widely accepted that about half of the stars form a relatively flat disc rotating clockwise on the sky, there is a substantial ongoing debate on whether there is a second, counter-clockwise disc of stars. By means of N-body simulations using our bhint code, we show that two highly inclined stellar discs with the observed properties cannot be recognised as two flat circular discs after 5 Myr of mutual interaction. Instead, our calculations predict a significant warping of the two discs, which we show to be apparent among the structures observed in the Galactic Centre. While the high eccentricities of the observed counter-clockwise orbits suggest an eccentric origin of this system, we show the eccentricity distribution in the inner part of the more massive clockwise disc to be perfectly consistent with an initially circular disc in which stellar eccentricities increase due to both non-resonant and resonant relaxation. We conclude that the relevant question to ask is therefore not whether there are two discs of young stars, but whether there were two such discs to begin with.

Making the case for \Arts for Sustainability\": A study of educators views of Education for Sustainability"
Creators: name: Emery, SG
Publisher: name: University Of Tasmania

description: The Decade of Education for Sustainable Development (2005-2014) is entering its closing stages and still the field of Education for Sustainability has not achieved the paradigm-shift required to progress beyond its present stasis in the realm of environmental education. In seeking to conceptualise new ways of effecting transformative EfS, this qualitative research explores teachers' perspectives of sustainability education and their perceptions of connections between arts education and Education for Sustainability. A study of teachers' perspectives was undertaken involving semi-structured interviews conducted with a purposive sample of five teachers following their participation in two EfS professional learning (PL) events during 2012. Clarke and Hollingsworth's (2002) model of teacher professional growth provided the framework for analysing the teachers' reports of change in their personal domain (knowledge and values) and their domain of practice resulting from their participation in the PL events. Findings from the study revealed that teachers identified arts rich education as a powerful transformative pedagogy for engaging students in EfS. Participation in the arts engages children emotionally and cognitively, and in so doing can affect children's values and motivate them to take action. EfS calls for children to value their planet and become active agents of change. This thesis concludes that the fields of arts education and EfS attend to concepts and goals that are each fundamental to the other and provides a conceptualisation of Arts for Sustainability as a new field in education.

description: Chrysanthemum is a significant genus belonging to one of the largest plant families, the Asteraceae. Among the over 40 recognized species, C. morifolium is best-known for its long history of cultivation and countless varieties. Like some other genera of this family, many Chrysanthemum species are producers of high levels of secondary metabolites. This review focuses on the largest class of plant secondary metabolites, namely terpenoids produced by Chrysanthemum species. An extensive literature search revealed a total of 390 terpenoids from these species, which include 183 monoterpenoids and 207 sesquiterpenoids. While some terpenes are produced by almost all of the investigated varieties/species of Chrysanthemum, many terpenoids show specificity to certain varieties or species, indicating species-specific functions. The enzymes and genes participating in the pathways for terpene biosynthesis are also described. In addition to a general overview, in this review we focus on isoprenyl diphosphate synthases and terpene synthases, two enzyme classes pivotal for generating the chemical diversity of terpenes, as established by our analysis of two sequenced genomes of Chrysanthemum. While our knowledge about the biological functions of terpenoids in Chrysanthemum is limited, we discuss their functions in chemical defenses against insects and microbial pathogens. Finally, we present the prospects of understanding the molecular basis of terpene biosynthesis in Chrysanthemum and elucidating its biological significance, as well as the prospects of translational research on terpene-based applications.
Continuous-Time Quantum Monte Carlo Approach to Singlet-Triplet Kondo Systems

description: Dynamical properties are studied numerically for a variant of the Kondo model with singlet and triplet crystalline electric field (CEF) levels where Kondo and CEF singlets compete for the ground state. Using the continuous-time quantum Monte Carlo method, we derive the $t$-matrix of conduction electrons and dynamical susceptibilities of local electrons without encountering the negative sign problem. When the CEF splitting is comparable to the Kondo temperature, the dynamical response has only a quasi-elastic peak. Nevertheless, the local single-particle spectrum shows an energy gap in strong contrast with the ordinary Kondo model.

Year: 2023

description: Presented in this thesis is MPEG VIRS: A content based video indexing and retrieval system. It is a prototype system that allows the automatic population and indexing of a database of MPEG-1 video files, based on colour, texture, and motion features. The system also allows searching of the database via a graphical sketch. The main focus of this thesis is the implementation of the motion indexing process, and additionally the integration of this component into the system as a whole. MPEG VIRS is designed to display the potential of a content based indexing and retrieval system in the growing need to provide tools to aid the management of large video databases, as well as to provide a framework for further research into this area.

description: We present a 2-port terahertz vector network analyzer (VNA) based on four continuous-wave (CW) photomixers and a pair of telecom-wavelength CW lasers. The presented optoelectronic VNA is free-space coupled and can operate continuously from 0.1 THz to 1 THz with a resolution of 2 MHz. We demonstrate two different applications with it: the determination of the material properties of a quartz wafer and the characterization of a terahertz distributed Bragg reflector (DBR).

Anomalies of conductivity behavior near the paramagnetic-antiferromagnetic transition in single-crystals La_{2}CuO_{4+δ}

description: The temperature dependences of resistance, R(T), of two single-crystals La_{2}CuO_{4+δ} samples have been studied with the aim to detect a possible change in the R(T) behavior induced by paramagnetic-antiferromagnetic (PM-AFM) transition. One of the samples with δ\lesssim 0.01, was fairly homogeneous in oxygen distribution (not phase-separated) with Neel temperature T_{N}\approx 266 K. Conductivity of this sample has been determined by Mott's variable-range hopping below T_N. The other, far less resistive, sample with δ\approx 0.05, was inhomogeneous (phase-separated) showing both PM-AFM (T_N\approx 205 K) and superconducting (T_c\approx 25 K) transitions. It is found that for the homogeneous sample the resistivity decreases above T_N far faster with temperature than below it (for both directions of measuring current, parallel and perpendicular to basal CuO_2 planes). A similar behavior of conductivity near PM-AFM transition is also found for the phase-separated and less resistive sample. In this case a clear kink in R(T) curve near T_N\approx 205 K can be seen. Furthermore, a transition to metallic (dR/dT>0) behavior occurs far enough above T_N. The observed behavior of the samples studied is related to increased delocalization of charge carriers above T_N. This is in accordance with decrease in the AFM correlation length and corresponding enhancement of the hole mobility above T_N known for low-doped lanthanum cuprates.

description: Judgements of wrongdoing in humans often hinge upon an assessment of whether a perpetrator acted out of free choice: whether they had more than one option. The classic inhibitors of free choice are constraint (e.g. having your hands tied together) and ignorance (e.g. being unaware that an alternative exists). Here, across two studies, we investigate whether chimpanzees consider these factors in their evaluation of social action. Chimpanzees interacted with a human experimenter who handed them a non-preferred item of food, either because they were physically constrained from accessing the preferred item (Experiment 1) or because they were ignorant of the availability of the preferred item (Experiment 2). We found that chimpanzees were more likely to accept the non-preferred food and showed fewer negative emotional responses when the experimenter was physically constrained compared with when they had free choice. We did not, however, find an effect of ignorance on chimpanzee's evaluation. Freedom of choice factors into chimpanzees' evaluation of how they are treated, but it is unclear whether mental state reasoning is involved in this assessment.
