description: The Australian Government has recently taken steps to reduce assistance levels in its economy. This paper reviews the levels of assistance prevailing in the agricultural sector in the mid- 1980's and discusses how the recent reform initiatives have reduced them. The implications of multilateral liberalization of agricultural policies for Australian agriculture are also considered.

description: We analyze in homological terms the homotopy fixed point spectrum of a T-equivariant commutative S-algebra R. There is a homological homotopy fixed point spectral sequence with E^2_{s,t} = H^{-s}_{gp}(T; H_t(R; F_p)), converging conditionally to the continuous homology H^c_{s+t}(R^{hT}; F_p) of the homotopy fixed point spectrum. We show that there are Dyer-Lashof operations beta^epsilon Q^i acting on this algebra spectral sequence, and that its differentials are completely determined by those originating on the vertical axis. More surprisingly, we show that for each class x in the $^{2r}-term of the spectral sequence there are 2r other classes in the E^{2r}-term (obtained mostly by Dyer-Lashof operations on x) that are infinite cycles, i.e., survive to the E^infty-term. We apply this to completely determine the differentials in the homological homotopy fixed point spectral sequences for the topological Hochschild homology spectra R = THH(B) of many S-algebras, including B = MU, BP, ku, ko and tmf. Similar results apply for all finite subgroups C of T, and for the Tate- and homotopy orbit spectral sequences. This work is part of a homological approach to calculating topological cyclic homology and algebraic K-theory of commutative S-algebras.

description: Master's Thesis. In 1837 the Ioway Indians drew a map to bring to treaty talks with the United States government. The 1837 Ioway Map project uses Geographic Information Systems (GIS) to help extract cultural, archaeological, and historical information from this rare document. Project goals include: documenting Ioway cartographic conventions; georeferencing the Ioway map to a modern base map; extracting spatial, historical, ecological and archaeological information from the georeferenced map; and designing a variety of digital (CD, web site) and non-digital (museum exhibit) presentation formats to broadly disseminate the project results. Centered on what is now the state of Iowa, the 1837 map shows 51 rivers, nine lakes, 23 villages, and over two dozen important Ioway Indian trails. Map features are unlabeled, but historic records indicate that it was designed around two major rivers, the Mississippi and the Missouri. GIS tools were helpful in evaluating the probable identifications of a number of the other hydrographic features. The Ioway encoded information about village size and population in their symbology, information that was systematically documented using pan, zoom, measurement, and geostatistical tools, with the results stored in attribute tables.

description: GATT negotiators are discussing elimination of trade-distorting agricultural policies. Trade reform would have profound implications on world beef markets. Barriers against foot and mouth disease may continue to divide world beef trade. Japan would cut its production and increase its dependence on imports. European beef prices would fall and the European Community would change from a net exporter to a net importer. Australia, New Zealand, Brazil, and Argentina would see higher prices and greater exports. North America would experience minor changes; both fed beef exports and manufacturing beef imports could increase. Beef prices would be more volatile following trade reform.

description: We consider the problem of estimating a ranking on a set of items from noisy pairwise comparisons given item features. We address the fact that pairwise comparison data often reflects irrational choice, e.g. intransitivity. Our key observation is that two items compared in isolation from other items may be compared based on only a salient subset of features. Formalizing this framework, we propose the salient feature preference model and prove a finite sample complexity result for learning the parameters of our model and the underlying ranking with maximum likelihood estimation. We also provide empirical results that support our theoretical bounds and illustrate how our model explains systematic intransitivity. Finally we demonstrate strong performance of maximum likelihood estimation of our model on both synthetic data and two real data sets: the UT Zappos50K data set and comparison data about the compactness of legislative districts in the US.

description: Faced with slow economic growth, falling petroleum revenues, and growing debt payments, the Mexican Government has changed the direction of its economic policies, including liberalization of both domestic and trade policies. Mexican agriculture, including the wheat sector, will likely be affected by reforms in trade policy and gradual elimination of consumer and producer subsidies. Reforms will alter domestic and international price relationships and influence production and consumption decisions in various agricultural sectors. This report analyzes and projects Mexican wheat supply and demand conditions in a liberalizing policy environment.
title: Self-assessment tools for person-environment fit

description: Background: Older people and people with disability have decreased functionality in the home compared to people without disabilities. Assessments of their functionality as well as of their home environment can lead to the prescription of home modifications and/or assistive technology that can improve their quality of life in the home. During periods of self-isolation and physical distancing, self-assessment tools can prove valuable for the preservation of the health of the tenants as well as the health professionals. Objectives: To explore and determine the existing self-assessment tools or the tools that can be transformed into self-assessment tools of functional ability and the appropriateness of the home. Search Methods: Systematic research through the HMinfo Library, Google Scholar and Standard Electronic Databases to retrieve 36 publications. Data Collection and analysis: 8 studies were analysed and included in the review. Results: Only one tool (CASPAR) was found to fulfil all requirements for a self-assessment tool of the person-home fit. A Telehealth version of the tool seems to be more effective in providing the necessary information for Occupational Therapists to be able to prescribe home modifications. Authors Conclusions: A self-assessment tool for the person-home environment fit should be developed and scientifically tested, utilizing existing tools elements.

research data management

description: Data Management Plans (DMP) play an important role for planning and conducting research activities and more and more researchers are facing requirements by their institution or funding agency for writing such a plan. Thereby, they are often misunderstood as an administrative task. Instead, DMPs are a powerful tool for efficient and secure collaboration and for the creation of research outputs of better quality and higher impact. A DMP will also help you to develop strategies for sharing and publishing your research data as openly as possible (and protecting them, when necessary). In this session, we will introduce the typical components of a DMP and discuss how the plan can be used actively throughout a research project. It will be targeted towards PhD students, but it will also be relevant for anyone working with research data.

description: We prove a query complexity variant of the weak polynomial Freiman-Ruzsa conjecture in the following form. For any $ε> 0$, a set $A \subset \mathbb{Z}^d$ with doubling $K$ has a subset of size at least $K^{-\frac{4}ε}|A|$ with coordinate query complexity at most $ε\log_2 |A|$. We apply this structural result to give a simple proof of the "few products, many sums" phenomenon for integer sets. The resulting bounds are explicit and improve on the seminal result of Bourgain and Chang.

Subjects: lupin, chickpea, grasspea, drought tolerance, agro-biological evalution

description: The most important cool season grain legumes (dry pea, chickpea, broad bean, lentil, lupins, grass pea and common vetch) are widely grown in many parts of the world. The aim of the current study was to test some of them under the drought-prone area of Sadovo (south-central region of Bulgaria) and to evaluate their adaptability based on physiological and agro-biological traits. The investigation was carried out at the experimental field of IPGR including several local accessions of white lupin (Lupinus albus L), chickpea (Cicer arietinum L) and grass pea (Lathyrus sativum L.). The chlorophyll content index of the leaves, used as criteria for drought tolerance, was measured by portable CCM 200 plus- Chlorophyll Content Meter. The assessment of agro-biological traits was performed according to the International Descriptor for each crop. Under the drought stress conditions the highest value of the chlorophyll content index was observed in three lupin accessions (BGR 6341, BGR3080, BGR3085), in two from chickpea (BGR 40417 and B9E0149) and in four from grass pea (BGR 40415, BGR 4835, BGR4847, BGR4834). The highest yield potential was established in two lupin (BGR 6341 and BGR 3084), two chickpea accessions (BGR 23151 and B9E0149) and three grass pea (BGR4832 and BGR40415). The selected accessions were included in the list for further investigations concerning drought tolerance and maintenance of relatively high yield potential under drought stress conditions.

description: We analyze the precise data obtained by the CMD-3 experiment on the $e^+e^-$ annihilation into two charged kaons in the vicinity of the $ϕ$ peak. A perfect fit is obtained only if a pole on the real axis below the reaction threshold is assumed. This can be interpreted as proof of the existence of the 2p state of kaonium, a compound of $K^+$ and $K^-$. The BaBar Collaboration data on the same process supports this conclusion and, in addition, points to the strong interaction as a dominant source of the binding energy. The possibility of discovering 2p kaonium in the $e^+e^-\rightarrow π^+π^-$ process is discussed. The 2p state of $K^0$-onium is indicated on the basis of the CMD-3 $e^+e^-\rightarrow K^0_SK^0_L$ data.

description: We have measured angular dimensions of 312 planetary nebulae from their images obtained in Halpha (or Halpha + [NII]). We have applied three methods of measurements: direct measurements at the 10% level of the peak surface brightness, Gaussian deconvolution and second-moment deconvolution. The results from the three methods are compared and analysed. We propose a simple deconvolution of the 10% level measurements which significantly improves the reliability of these measurements for compact and partially resolved nebulae. Gaussian deconvolution gives consistent but somewhat underestimated diameters compared to the 10% measurements. Second-moment deconvolution gives results in poor agreement with those from the other two methods, especially for poorly resolved nebulae. From the results of measurements and using the conclusions of our analysis we derive the final nebular diameters which should be free from systematic differences between small (partially resolved) and extended (well resolved) objects in our sample.

description: Milk is produced worldwide, but dairy trade is dominated by manufactured dairy products. Only about 5 percent of total world milk production is traded internationally. If freer trade existed, there would likely be higher international dairy prices but the effects on international price stability and trade volumes would be uncertain. The European Community would likely face the greatest changes in adapting to liberalized trade. The United States would likely remain a minor but potentially more active participant in international dairy markets. This is report describes international dairy production, consumption, and trade; trade policies of dairy trading nations; and examines market adjustments that might occur under agricultural trade liberalization.

description: Controlling the size and shape of nanopores in two-dimensional materials is a key challenge in applications such as DNA sequencing, sieving, and quantum emission in artificial atoms. We here investigate experimentally and theoretically triangular vacancies in (unconventional) Bernal-stacked AB-h-BN formed using a high-energy electron beam. Due to the geometric configuration of AB-h-BN, triangular pores in different layers are aligned, and their sizes are controlled by the duration of the electron irradiation. Interlayer covalent bonding at the vacancy edge is not favored, as opposed to what occurs in the more common AA'-stacked BN. A variety of monolayer, concentric and bilayer pores in bilayer AB-h-BN are observed in high-resolution transmission electron microscopy and characterized using ab initio simulations. Bilayer pores in AB-h-BN are commonly formed, and grow without breaking the bilayer character. Nanopores in AB-h-BN exhibit a wide range of electronic properties, ranging from half-metallic to non-magnetic and magnetic semiconducting. Therefore, because of the controllability of the pore size, the electronic structure is also highly controllable in these systems, and can potentially be tuned for particular applications.

description: Motivated by the work of Klebanov and Polyakov [hep-th/0210114] on the relationship of the large N O(N) vector model in three-dimensions to AdS_4 and higher spin representations, we attempt to find analogous connections for AdS_5. Since the usual O(N) vector model in four-dimensions is inconsistent, we consider the (consistent) large N gauged vector model and a N=1 supersymmetric analogue in four-dimensions. Both these theories have UV and IR fixed points, and are candidates for a (α')^-1 expansion in AdS_5, a conjectured AdS_5/CFT correspondence and higher-spin representations in the bulk theory.

description: This study examines in the context of an open economy framework the relative significance of domestic and foreign shocks as sources of macroeconomic fluctuations in a small developing oil-exporting economy, the Sultanate of Oman. The empirical methodology we employ to identify our shocks is the structural vector autoregression (SVAR) model with block exogeneity constraints. The results from our forecast error variance decompositions (FEVDs) indicate that domestic shocks, namely nominal money and supply shocks are the most important factors driving non-oil output growth volatility in Oman. External factors, on the other hand, are found to be of less importance in explaining the same.

description: The intermetallic compound, YRhAl, has been prepared and is found to be isomorphic with RRhAl (R=Pr, Nd, Gd, Ho and Tm) compounds crystallizing in the orthorhombic TiNiSi-type structure (Space group Pnma). Heat capacity and electrical resistivity measurements in the He-3 temperature range reveal that this compound is superconducting with a transition temperature, Tc, of 0.9 K. The electronic specific heat coefficient, gamma, and the Debye temperature are found to be 6.1 mJ/mole K and 197 K, respectively. The specific heat jump at the superconducting transition temperature is found to be consistent with the BCS weak-coupling limit. This combined with the earlier observation of superconductivity in LaRhAl (Tc = 2.4 K) having a different structure than that of YRhAl, suggests that the underlying structure is not very crucial for the occurrence of superconductivity in RRhAl series of compounds.

description: A common assumption in non-parametric regression models is the independence of the covariate and the error. Some procedures have been suggested for testing that hypothesis. This paper considers a test, whose test statistic compares estimators of the joint and the product of the marginal characteristic functions of the covariate and the error. It is proposed to approximate the null distribution of such statistic by means of a weighted bootstrap estimator. The resulting test is able to detect any fixed alternative as well as local alternatives converging to the null at the rate n−1/2, n denoting the sample size. The finite sample performance of this approximation is assessed by means of a simulation study, where it is also compared with other estimators. This study reveals that, from a computational point of view, the proposed approximation is very efficient. Two real data set applications are also included.

description: We study Nesterov's accelerated gradient method with constant step-size and momentum parameters in the stochastic approximation setting (unbiased gradients with bounded variance) and the finite-sum setting (where randomness is due to sampling mini-batches). To build better insight into the behavior of Nesterov's method in stochastic settings, we focus throughout on objectives that are smooth, strongly-convex, and twice continuously differentiable. In the stochastic approximation setting, Nesterov's method converges to a neighborhood of the optimal point at the same accelerated rate as in the deterministic setting. Perhaps surprisingly, in the finite-sum setting, we prove that Nesterov's method may diverge with the usual choice of step-size and momentum, unless additional conditions on the problem related to conditioning and data coherence are satisfied. Our results shed light as to why Nesterov's method may fail to converge or achieve acceleration in the finite-sum setting.

description: Strengthening constraints on new physics from the B -> X_s gamma branching ratio requires improving accuracy in the measurements and the Standard Model predictions. To match the expected Belle-II accuracy, Next-to-Next-to-Leading Order (NNLO) QCD corrections must be calculated without the so-far employed interpolation in the charm-quark mass m_c. In the process of evaluating such corrections at the physical value of m_c, we have finalized the part coming from diagrams with closed fermion loops on the gluon lines that contribute to the interference of the current-current and photonic dipole operators. We confirm several published results for corrections of this type, and supplement them with a previously uncalculated piece. Taking into account the recently improved estimates of non-perturbative contributions, we find B_{s gamma} = (3.40 \pm 0.17) * 10^{-4} and R_gamma = B_{(s+d) gamma}/B_{c l nu} = (3.35 \pm 0.16) * 10^{-3} for E_gamma > 1.6 GeV in the decaying meson rest frame.

Dis /abling exclusion, en /abling access: Identifying and removing barriers in archaeological practice for persons with (dis /)abilities
Creators: name: Fraser, Meredith A.
Publisher: name: American University
Year: 2023

description: This research examines the accessibility of contemporary archaeological practice for archaeologists with (dis/)abilities. To accomplish this, it draws on design literature that considers how products are developed, produced and used. This literature suggests that design practices can either be outcome-focused or user-focused, where the former strategy produces less accessible products and the latter strategy creates products that are available to a broader spectrum of end-users. The design-based framework outlined here is mobilized in this research to understand archaeology as a discipline that is focused on outcomes as opposed to users. In particular, archaeological praxis is centered on pursuing, producing and protecting objects. These object-focused goals place demands on archaeologists that can function as social, physical and economic barriers which reduce the accessibility of the discipline for some archaeologists with (dis/)abilities. As barriers in archaeological practice stem from the discipline's focus on object-centered outcomes, this research suggests that a shift in disciplinary focus to include a greater concern for users is fundamental to reducing barriers and improving the accessibility of archaeological practice. To this end, the present research proposes that archaeologists use the Principles of Universal Design (UD) and aspects of Inclusive Design (ID) to consider users in addition to the object-focused outcomes that currently underpin disciplinary praxis. Case studies drawn from community archaeology initiatives and from research participants' experiences demonstrate how archaeologists have already used aspects of UD and ID to successfully reduce and eliminate barriers and increase disciplinary access. These initiatives support my research's call for the more formal, widespread integration of the Principles of UD and aspects of ID into archaeological praxis by establishing a precedent for their use in diverse archaeological contexts. By implementing UD and ID into both project development and daily practice, archaeologists can create a discipline that is better able to respond to all archaeologists' needs, interests and changing abilities while simultaneously fulfilling outcomes related to objects.

description: Parton-parton collisions do not neutralize local color charges in the quark-gluon plasma as they only redistribute the charges among momentum modes. We discuss color diffusion and color conductivity as the processes responsible for the neutralization of the plasma. For this purpose, we first compute the conductivity and diffusion coefficients in the plasma that is significantly colorful. Then, the time evolution of the color density due to the conductivity and diffusion is studied. The conductivity is shown to be much more efficient than the diffusion in neutralizing the plasma at the scale longer than the screening length. Estimates of the characteristic time scales, which are based on close to global equilibrium computations, suggest that first the plasma becomes white and then the momentum degrees of freedom thermalize.

description: Recurrent and convolutional neural networks are the most common architectures used for time series forecasting in deep learning literature. These networks use parameter sharing by repeating a set of fixed architectures with fixed parameters over time or space. The result is that the overall architecture is time-invariant (shift-invariant in the spatial domain) or stationary. We argue that time-invariance can reduce the capacity to perform multi-step-ahead forecasting, where modelling the dynamics at a range of scales and resolutions is required. We propose ForecastNet which uses a deep feed-forward architecture to provide a time-variant model. An additional novelty of ForecastNet is interleaved outputs, which we show assist in mitigating vanishing gradients. ForecastNet is demonstrated to outperform statistical and deep learning benchmark models on several datasets.
Cultural and state nationalism: South Korean and Japanese relations with China
Creators: name: Kim, Hankwon
Publisher: name: American University
Year: 2023

description: This research is a comparative study of South Korean and Japanese nationalisms and their impact on the two countries' relations with China during and after the Cold War era. I do recognize overall contributions of realist and liberalist explanations for the regional politics as well as the importance of their central factors, such as security, trade, military, and values. However, this research argues that the factors of nationalism have been necessary to explain and understand Northeast Asian international relations in the post-Cold War era. In fact, there are some regional phenomena that the two traditional theories could not explain completely, such as the ROK's pro-North Korean policy in the face of the unclear threats, or increasing nationalistic frictions between China and Japan in spite of their strong economic ties. In order to prove the significant influence of nationalism in the post-Cold War era, this research discusses four case studies (i.e. anti-Americanism in the ROK, North Korean nuclear issues, the Yasukuni shrine issues, and history textbook revisions in Japan). It also utilizes the notions of cultural and state nationalism in order to compare the characteristics of South Korean and Japanese nationalisms and to understand contrasting directions and mechanisms of the two countries' nationalistic influences in the post-Cold War era. This research concludes that, first of all, due to the uniqueness of cultural and historical background of East Asian countries, the factors of nationalism offer more comprehensive explanations combined with neorealist and neoliberal perspectives to grasp the nature of Northeast Asian international relations in the post-Cold War era. Second, although cultural and state nationalism have existed together in the two countries' histories and shared many ideas and values in each nation, the ROK's cultural nationalism has overwhelmed state nationalism and worked for better relations, rather than harm, with China in the post-Cold War era, while Japanese state nationalism has generated significant tensions and frictions in the Sino-Japanese relations since the 1980s. Finally, for a deeper analyses of the post-Cold War anti-Americanism and pro-China tendency in South Korea, this research highlights and elaborates the notions of the anti-hegemonic nature of Korean nationalism and South Korea's non-respected privileged elite group, which is rooted in Japanese colonialism. This research argues that the two points have interacted, directly or indirectly, to worsen anti-Americanism in South Korea. At the same time, they generated the South Korean pro-China tendency in the post-Cold War era. However, this research also points out that when the issues of Chinese "Dongbei Project" and of North Korean refugees in China recently emerged, the anti-hegemonic characteristic of Korean nationalism harmed South Korean people's image of China and created a chance to reevaluate the meaning of the U.S. to South Korea.
Effect of the Fast Nuclear Electromagnetic Pulse on the Electric Power Grid Nationwide: A Different View

description: This paper primarily considers the potential effects of a single high-altitude nuclear burst on the U.S. power grid. A comparison is made between EMP and natural phenomena such as lightning. This paper concludes that EMP is no more harmful to the power grid than its counterparts in nature. An upper limit of the electric field of the very fast, high-amplitude EMP is derived from first principles. The resulting values are significantly lower than the commonly presented values. Additional calculations show that the ionization produced by a nuclear burst severely attenuates the EMP.

description: We first present a determinant inequality related to partial traces for positive semidefinite block matrices. Our result extends a result of Lin [Czech. Math. J. 66 (2016)] and improves a result of Kuai [Linear Multilinear Algebra 66 (2018)]. Moreover, we provide a unified treatment of a result of Ando [ILAS Conference (2014)] and a recent result of Li, Liu and Huang [Operators and Matrices 15 (2021)]. Furthermore, we also extend some determinant inequalities involving partial traces to a larger class of matrices whose numerical ranges are contained in a sector. In addition, some extensions on trace inequalities for positive semidefinite $2\times 2$ block matrices are also included.
