description: Conflicts of interest between irrigation and aquaculture in water use from reservoirs in Vietnam can be resolved when trade-offs in the economic value of water can be quantified over time. Determining these trade-offs can be used as a benchmark for making decisions about managing reservoirs tending to develop rural areas in Vietnam. To solve this problem, a stochastic dynamic programming model was constructed. This model maximizes the expected net present values generated by both agriculture and aquaculture by finding the optimal release paths throughout a year, under conditions of uncertain rainfall. The model was constructed using two main components. First, a dated water production function is used to evaluate responses of crop yields for different levels of applied irrigation. Second, a bio-economic model for reservoir fisheries is employed to estimate fish yields at different levels of water during a harvest season. Using this model, we present a case study of reservoir water management in Vietnam.

description: Hilbert-Schmidt distance is one of the prominent distance measures in quantum information theory which finds applications in diverse problems, such as construction of entanglement witnesses, quantum algorithms in machine learning, and quantum state tomography. In this work, we calculate exact and compact results for the mean square Hilbert-Schmidt distance between a random density matrix and a fixed density matrix, and also between two random density matrices. In the course of derivation, we also obtain corresponding exact results for the distance between a Wishart matrix and a fixed Hermitian matrix, and two Wishart matrices. We verify all our analytical results using Monte Carlo simulations. Finally, we apply our results to investigate the Hilbert-Schmidt distance between reduced density matrices generated using coupled kicked tops.

description: Recent study by Meat & Livestock Australia revealed that cost competitiveness and market development issues in supply chain are the major factors for a long term decline of the Australian Beef industry. This study, based on the explanation of transaction cost theory argues that competitive performance of an industry depends on improving cost efficiency across the whole of supply chain, the underlying value chain, and the relationship among the stakeholders in the industry. With a main objective to investigate the underlying factors of developing competent inter-firm relationship that influence the supply chain performance and competitiveness, this study presents details of a survey carried out and tests the hypothesis that inter-organizational relationships in supply chain and its antecedents have impact on the performance of Australian beef industry and thus have impact on the competitiveness of the industry. Data were collected through a telephone survey of 315 firms in the beef industry from the states of Western Australia and Queensland. The sample respondents were categorized as input suppliers, beef-cattle producers, processors, retailers/exporters, and wholesalers. The data were analysed using the partial least square based structural equation modelling. PLS analysis reveals that ‘Transaction Climate’ is the strongest determinants of developing a competent relationship, while negotiation power, presence of industry competitors, and the degree of vertical coordination significantly influence the relationship strength. Findings also demonstrate that relationship strength is the most prevalent source of performance and competitiveness, while SC performance highly positively influences the Competitiveness of beef industry. Thus this study identifies significant antecedents and consequences of Supply Chain Performance in Australian beef industry, which are strategic and extremely important information for beef producers, processors, retailers, and other stakeholders for appropriate planning and benchmarking.

Rotational friction on small globular proteins: Combined dielectric and hydrodynamic effect

description: Rotational friction on proteins and macromolecules is known to derive contributions from at least two distinct sources -- hydrodynamic (due to viscosity) and dielectric friction (due to polar interactions). In the existing theoretical approaches, the effect of the latter is taken into account in an {\it ad hoc} manner, by increasing the size of the protein with the addition of a hydration layer. Here we calculate the rotational dielectric friction on a protein ($ζ_{DF}$) by using a generalized arbitrary charge distribution model (where the charges are obtained from quantum chemical calculation) and the hydrodynamic friction with stick boundary condition, ($ζ_{hyd}^{stick}$) by using the sophisticated theoretical technique known as tri-axial ellipsoidal method, formulated by Harding [S. E. Harding, Comp. Biol. Med. {\bf 12}, 75 (1982)]. The calculation of hydrodynamic friction is done with only the dry volume of the protein (no hydration layer). We find that the total friction obtained by summing up $ζ_{DF}$ and $ζ_{hyd}^{stick}$ gives reasonable agreement with the experimental results, i.e., $ζ_{exp} \approx ζ_{DF} + ζ_{hyd}^{stick}$.

description: This paper analyzes the optimal informative advertising and price policies of a monopolist who sells a new experience good over time to a population of heterogeneous buyers. Under certain conditions, the advertising rate first increases and then decreases over the marketing cycle with a peak occurring at the end of the introductory period when prices are low. Advertising lowers introductory prices but also shortens the period during which they are offered. Advertising raises the share of consumers who know their valuation in the long-run but not necessarily in the short-run

description: Two independent sets of Chandra and HST images of the nuclear region of M31 allow registration of X-ray and optical images to 0.1''. This registration shows that none of the bright (10^{37} erg/s) X-ray sources near the nucleus is coincident with the central super-massive black hole, M31*. A 50ks Chandra HRC image shows 2.5 sigma evidence for a faint (3 x 10^{35} erg/s), apparently resolved source which is consistent with the position of the M31*. The Bondi radius of M31* is 0.9'', making it one of the few super-massive black holes with a resolvable accretion flow. This large radius and the previous detections of diffuse, X-ray emitting gas in the nuclear region make M31* one of the most secure cases for a radiatively inefficient accretion flow and place some of the most severe constraints on the radiative processes in such a flow.

description: We report site percolation thresholds for square lattice with neighbor interactions at various increasing ranges. Using Monte Carlo techniques we found that nearest neighbors (N$^2$), next nearest neighbors (N$^3$), next next nearest neighbors (N$^4$) and fifth nearest neighbors (N$^6$) yield the same $p_c=0.592...$. At odds, fourth nearest neighbors (N$^5$) give $p_c=0.298...$. These results are given an explanation in terms of symmetry arguments. We then consider combinations of various ranges of interactions with (N$^2$+N$^3$), (N$^2$+N$^4$), (N$^2$+N$^3$+N$^4$) and (N$^2$+N$^5$). The calculated associated thresholds are respectively $p_c=0.407..., 0.337..., 0.288..., 0.234...$. The existing Galam--Mauger universal formula for percolation thresholds does not reproduce the data showing dimension and coordination number are not sufficient to build a universal law which extends to complex lattices.

description: Despite of the important role international migration fills in the United States’ labor-intensive agricultural sector, few studies have addressed the individual characteristics and circumstances surrounding entry and exit by farm laborers. With increasing public attention on international migrant labor, policymakers have a need to understand the labor market patterns of these workers if they are to formulate appropriate immigration reforms, including temporary worker programs geared towards agriculture. In this analysis, we model the likelihood of entering agricultural employment by migrants to the United States. Using data from the Mexican Migration Project we find that migrants with higher levels of education and a greater command of English are less likely to work as agricultural laborers. Those that do enter agricultural occupation stay in the United States for shorter periods of time per trip than those who enter non-agricultural occupation. In future analysis we will attempt to model the demand for agricultural farm work as a determinant of the decision by migrants to enter the U.S. market for hired farm labor.

description: This paper studies whether a seller achieves higher profits by providing consumers with information that allows them to distinguish between products from different countries, and how mandatory provision of such information impacts welfare. We analyze a model of multi-product monopoly with horizontal differentiation and random country-specific input costs. We find that if the variability in the input costs is sufficiently high and the share of consumers with high valuations is in some intermediate range, the seller prefers to withhold information about product origin. Mandatory labeling of products with their country of origin may reduce or increase welfare depending on the share of consumers with high valuations. We also discuss extensions of the basic model that allow for continuous distributions of valuations and input costs, and consumer learning.

description: Similar to biological evolution and speciation we define a language through a string of 8 or 16 bits. The parent gives its language to its children, apart from a random mutation from zero to one or from one to zero; initially all bits are zero. The Verhulst deaths are taken as proportional to the total number of people, while in addition languages spoken by many people are preferred over small languages. For a fixed population size, a sharp phase transition is observed: For low mutation rates, one language contains nearly all people; for high mutation rates, no language dominates and the size distribution of languages is roughly log-normal as for present human languages. A simple scaling law is valid.

description: Quantum curves arise from Seiberg-Witten curves associated to 4d $\mathcal{N}=2$ gauge theories by promoting coordinates to non-commutative operators. In this way the algebraic equation of the curve is interpreted as an operator equation where a Hamiltonian acts on a wave-function with zero eigenvalue. We find that this structure generalises when one considers torus-compactified 6d $\mathcal{N}=(1,0)$ SCFTs. The corresponding quantum curves are elliptic in nature and hence the associated eigenvectors/eigenvalues can be expressed in terms of Jacobi forms. In this paper we focus on the class of 6d SCFTs arising from M5 branes transverse to a $\mathbb{C}^2/\mathbb{Z}_k$ singularity. In the limit where the compactified 2-torus has zero size, the corresponding 4d $\mathcal{N}=2$ theories are known as class $\mathcal{S}_k$. We explicitly show that the eigenvectors associated to the quantum curve are expectation values of codimension 2 surface operators, while the corresponding eigenvalues are codimension 4 Wilson surface expectation values.

Looking on the bright side : downward counterfactual thinking and coping with stressful life events
Creators: name: White, Katherine
Publisher: name: University of British Columbia
Year: 2009

description: Past research on counterfactual thinking suggests that downward counterfactuals are not frequently generated in response to negative events. An interrelated set of 5 studies examined whether, and under what conditions, people generate more downward than upward counterfactuals in response to stressful life events. Study 1 found that those with Chronic Fatigue Syndrome generated more downward than upward counterfactuals regarding their condition. Study 2 found that, in response to the events of September 11th, people tended to generate more downward than upward counterfactuals, particularly when they were motivated to make themselves feel better. In Study 3, in which motives were manipulated, those motivated by self-enhancement generated more downward counterfactuals than those motivated by self-improvement or those given no motives. Furthermore, European-Canadians (who are presumably more motivated to feel good about the self) generated more downward counterfactuals than Asian Canadians. Study 4 found no significant difference between the number of upward and downward counterfactuals recalled for mild vs. severe negative events. Once again European-Canadians generated more downward than upward counterfactuals, whereas Asian- Canadians did not demonstrate this tendency, providing further support for the notion that those who are motivated to feel good about the self generate more downward counterfactuals. These cultural differences in counterfactual thinking were more pronounced in response to severe than mild negative life events. Moreover, participants reported less negative moods, more positive moods, and more affect-regulation motives associated with downward counterfactuals than with upward counterfactuals. Finally, in Study 5, those who were not given the opportunity to affirm important values generated more downward than upward counterfactuals, whereas those who completed a selfaffirmation task did not demonstrate this tendency. Taken together, the results advance our understanding of downward counterfactual thinking in response to stressful life events, and suggest that this tendency is related to the desire to repair moods and see the self in a positive light.
Covariance of the matter power spectrum including the survey window function effect: N-body simulations vs. fifth-order perturbation theory on grid

description: We present a Next-to-next-to-leading (fifth or NNLO) order calculation for the covariance matrix of the matter power spectrum, taking into account the effect of survey window functions. Using the grid-based calculation scheme for the standard perturbation theory, GridSPT, we quickly generate multiple realizations of the nonlinear density fields to fifth order in perturbation theory, then estimate the power spectrum and the covariance matrix from the sample. To the end, we have obtained the non-Gaussian covariance originated from the one-loop trispectrum without explicitly computing the trispectrum. By comparing the GridSPT calculations with the N-body results, we show that NNLO GridSPT result reproduces the N-body results on quasi-linear scales where SPT accurately models nonlinear matter power spectrum. Incorporating the survey window function effect to GridSPT is rather straightforward, and the resulting NNLO covariance matrix also matches well with the N-body results.

description: This research extends past work by Shonkwiler and Yen (1999) by allowing for distributional flexibility and nonlinear responses in the form of established semiparametric and nonparametric regressions. The proposed models are shown to outperform the parametric version typically used in demand analysis to characterize a system of censored equations in terms of model fit and prediction power. Using the developed models, we derive elasticities associated with different individual-specific scenarios with regard to the recently proposed “penny-an-ounce” tax on soft drinks sweetened with sugar.

description: Micro-focus Brillouin light scattering is a powerful technique for the spectroscopic and spatial characterization of elementary excitations in materials. However, the small momentum of light limits the accessible excitations to the center of the Brillouin zone. Here, we utilize a metallic nanoantenna fabricated on the archetypal ferrimagnet yttrium iron garnet to demonstrate the possibility of Brillouin light scattering from large-wavevector, high-frequency spin wave excitations that are inaccessible with free-space light. The antenna facilitates sub-diffraction confinement of electromagnetic field, which enhances the local field intensity and generates momentum components significantly larger than those of free-space light. Our approach provides access to high frequency spin waves important for fast nanomagnetic devices, and can be generalized to other types of excitations and light scattering techniques.

description: Wine is a product whose value largely depends on the reputation associated with its region of production. China is a newcomer and latecomer to wine production and consumption. Wine consumption, especially imported wine, rarely exists outside of major urban areas. Therefore, understanding the Chinese local markets and consumer preference for wine products is important for foreign wine producers. WTP (Willingness-to-Pay), in economics, is the maximum amount a person would be willing to pay for a good, which is a useful tool to address consumers’ preference. In our study, we investigate the effects of information and origin of production on Chinese consumers’ WTP for wine. By using a second-price sealed-bid auction mechanism, which was first developed by Vickrey (1961), we organized experimental auctions in both Beijing and Shanghai, China. The items for auctions are four different wine products originated in China, France, USA, and Australia. And there are two comparison groups, with or without information exposure. With 436 participants in total, our experiments collected data on their WTP’s and socio-demographics. Our data shows that participants would like to pay the highest price for the wine from France, while their WTP for the Chinese wine is the lowest among the four. Furthermore, we find important factors affecting their WTP for wine, including age, gender, employment status, education status, household income, and household size. Our results provide meaningful and insightful marketing suggestions for the “new world” and Chinese wine producers, such as the target consumers and pricing strategy.

description: Heisenberg's uncertainty principle, which imposes intrinsic restrictions on our ability to predict the outcomes of incompatible quantum measurements to arbitrary precision, demonstrates one of the key differences between classical and quantum mechanics. The physical systems considered in the uncertainty principle are static in nature and described mathematically with a quantum state in a Hilbert space. However, many physical systems are dynamic in nature and described with the formalism of a quantum channel. In this paper, we show that the uncertainty principle can be reformulated to include process-measurements that are performed on quantum channels. Since both quantum states and quantum measurements are themselves special cases of quantum channels, our formalism encapsulates the uncertainty principle in its utmost generality. More specifically, we obtain expressions that generalize the Maassen-Uffink uncertainty relation and the universal uncertainty relations from quantum states to quantum channels.

description: We propose an electroweak model which is compatible with the UV insensitive anomaly mediated supersymmetry breaking. The model is an extension of the NMSSM by adding vector-like matter fields which can drive the soft scalar masses of the singlet Higgs field negative and the successful electroweak symmetry breaking is achieved. Viable parameter regions are found to preserve perturbativity of all the coupling constants up to the Planck scale. With this success, the model becomes a perfect candidate of physics beyond the standard model without the FCNC and CP problem. The cosmology is also quite interesting. The lightest neutralino is the wino which is a perfect cold dark matter candidate assuming the non-thermal production from the gravitino decay. There is no gravitino problem because it decays before the BBN era, and thus the thermal leptogenesis works. The cosmological domain wall problem inherent in the NMSSM is absent since the Z_3 symmetry is broken by the QCD instanton effect in the presence of the vector-like quarks. We also briefly comment on a possible solution to the strong CP problem a la the Nelson-Barr mechanism.

description: Agricultural economists are increasingly being asked by policy makers and food industry to evaluate the efficacy of labeling programs or to assess if consumers are mislead by existing labeling programs. International food agencies, however, often rely only on stated preference methods in the form of attitude and perception measurement to directly assess consumers’ understanding and evaluation of label information and its importance to their purchase decisions. Attitudinal measures are often criticized for potentially providing biased estimates of true preferences, as they tend to overstate the importance of product characteristics when evaluated separately. Choice experiments, on the other hand, provide a methodological tool for a holistic product evaluation and force respondents to trade-off several attributes against another. In this study, we assess how closely consumers’ attitudinal measures with respect to food product labeling alternatives (pre- and post-information) correlate with estimates of relative value and importance from a discrete choice experiment (DCE). Data from a recent study commissioned by the Australian wine industry is used to examine whether consumers are being mislead by current food labeling policy which allows a product, only partially derived from wine and of lower technical quality, to be labeled as “Wine Product”. In combination with origin labeling consumers are potentially being misled by the combined label “Wine Product of Australia”. Thus, the overall objective of this research is to compare the results of attitudinal versus choice based methods to examine the efficacy of each method when assessing the impact of labeling information and policy on consumer behavior.

The impact of access and adherance on mortality from HIV disease in the era of modern antiretroviral therapy
Creators: name: Wood, Evan
Publisher: name: University of British Columbia
Year: 2009

description: Objectives: To identify the proportion of HIV-related deaths that occur among persons who have never accessed antiretroviral therapy; model the potential public health impact of improved access to antiretroviral therapy; determine the role of socio-economic status on access and as a predictor of HIV disease progression; evaluate the impact of adherence to HAART on survival rates; and to determine rates of therapy discontinuation and virological response among HIV-infected injection drug users. Methods: British Columbia's HIV/AIDS Drug Treatment Program provides antiretroviral therapy to all eligible HIV positive persons in British Columbia free of charge. Data from the Centre as well as mortality data from Vital Statistics, socioeconomic data from Statistics Canada, and prescription refill data from pharmacies were used to evaluate and model mortality patterns and antiretroviral therapy use among HIV-infected individuals. Results: Overall, 32.7% of persons who have died of HIV/AIDS during the period 1995 - 2001 died without accessing antiretroviral therapy. Several markers of socioeconomic status were associated with non-receipt of therapy, and socio-economic status was associated with the receipt of sub-optimal therapy among those who initiated treatment. Models developed also indicate that improved uptake of antiretroviral therapy among injection drug users could have a substantial impact on life expectancy and mortality in this setting. Among patients who initiated triple therapy, rates of sub-optimal adherence are common, and are associated with markedly higher rates of mortality. In particular, patients with a history of injection drug use may be at risk of treatment cessation and poor virologic response. Conclusions: Limited access to antiretroviral therapy, particularly among certain sub-populations, has contributed on to ongoing AIDS mortality. Among persons who initiate therapy, the problem of limited access has been compounded by suboptimal adherence and prescription patterns, as well as high rates of treatment discontinuation. These data suggest that novel strategies are required to improve access and adherence to antiretroviral therapy despite a universal healthcare system that provides antiretrovirals and HIV/AIDS care free of charge.

description: This paper considers self-conformal iterated function systems (IFSs) on the real line whose first level cylinders overlap. In the space of self-conformal IFSs, we show that generically (in topological sense) if the attractor of such a system has Hausdorff dimension less than $1$ then it has zero appropriate dimensional Hausdorff measure and its Assouad dimension is equal to $1$. Our main contribution is in showing that if the cylinders intersect then the IFS generically does not satisfy the weak separation property and hence, we may apply a recent result of Angelevska, Käenmäki and Troscheit [BLMS, 2020]. This phenomenon holds for transversal families (in particular for the translation family) typically, in the self-similar case, in both topological and in measure theoretical sense, and in the more general self-conformal case in the topological sense.

description: Энергетики прогрессивно становяться частью субкультуры. Вот почему, по мнению ВОЗ (2014), риски тяжелого потребления энергетических напитков (ЭН) среди молодых людей и их долгосрочный эффект, оставаясь в значительной степени без внимания ученых и общественности, могут стать серьезной проблемой общественного здравоохранения в будущем. Целью данной работы является изучение морфофункциональных изменений слизистой оболочки желудка, с помощью лабораторных исследований при употребления энергетических напитков. Коррекция побочных эффектов, вызываемых энергетическими напитками, с помощью местных лечебных веществ считается сегодня весьма актуальной. В этой статье рассматриваются эти проблемы окруженный светом. Поскольку некоторые масла содержат антиоксиданты, незаменимые жирные кислоты, фосфолипиды, фитостерины и другие биологически активные соединения, важно оценить эффективность этих масел в коррекции изменений, вызванных ЭН в желудке.

description: A dairy products manufacturer wishing to expand into university foodservice operations collaborated with a graduate marketing class to research student preferences regarding the Company’s products. Baseline and follow-up stated choice surveys and conditional logit analyses were conducted at a land-grant university where the Company’s products were introduced. Brand awareness grew but remained low during the study period. Average WTP estimates for the Company’s most popular product approximated the retail price and resembled WTP for a competing brand. Average WTP for the Company’s other products, however, was considerably lower than the retail price. Significant WTP differences existed among some consumer segments.

description: This paper deals with the effect of constitutional rules on agricultural policy outcomes in a panel of observations for more than 70 developing and developed countries in the 1955-2005 period. Testable hypotheses are drawn from recent developments in the comparative politics literature that see political institutions as key elements in shaping public policies. Using differences-in-differences regressions we find a positive effect of a transition into democracy on agricultural protection. However, this average effect masks substantial heterogeneities across different forms of democracy. Indeed, what matters are transitions to proportional (as opposed to majoritarian) democracies, as well as to permanent (as opposed to temporary) democracies. Moreover, while we do not detect significant differences across alternative forms of government (presidential versus parliamentary systems), there is some evidence that the effect of proportional election is exacerbated under parliamentary regimes, and diminished under presidential ones.
