Cultural landscape and living heritage in the Vineyard Landscape of Langhe-Roero and Monferrato
Creators: name: Settimini, Elena
Publisher: name: University of Leicester
Year: 2020
Subjects: Uncategorized

description: This research investigates how the concepts of ‘heritage’, ‘landscape’ and ‘participation’ are articulated within legal documents and policies which manage heritage (in particular the World Heritage Convention and the European Landscape Convention) and by laypersons. The purpose is to explore the semantic differences existing between these two categories and to understand the implications for the development of participative heritage preservation and management policies within cultural landscapes. I argue that power relationships between the categories of ‘experts’ and ‘non-experts’ produce different articulations of heritage values and meanings, and consequently generate disengagement in the identification, definition and preservation of a heritage site. This discussion is developed through the analysis of an Italian case study, the UNESCO World Heritage vineyard landscape of Langhe-Roero and Monferrato, inscribed in the World Heritage List as a ‘cultural landscape’ since 2014. The data collection and generation have been divided into two main focuses: preliminary documentary research combined with interviews with different typologies of stakeholders (heritage professionals, local people and women wine producers). I suggest that the development of participatory methodologies based on consultation and negotiation could generate a more inclusive identification of heritage values and meanings, attentive to different ways of articulating, preserving and managing landscape. This does not mean resolving all the conflicts or achieving a general consensus, but rather providing people with capacity building tools and skills, in order to facilitate the articulation of heritage values and also to rethink - and maybe redefine - heritage markers. To conclude, I argue that the lack, or presence, of stories in the landscape has important cultural, political, social and economic consequences in the present and that the links between these factors have to be revealed in order to develop more inclusive practices.
Effects of Non-Conformal Boundary on Entanglement Entropy

description: Spacetime boundaries with canonical Neuman or Dirichlet conditions preserve conformal invarience, but "mixed" boundary conditions which interpolate linearly between them can break conformal symmetry and generate interesting Renormalization Group flows even when a theory is free, providing soluble models with nontrivial scale dependence. We compute the (Rindler) entanglement entropy for a free scalar field with mixed boundary conditions in half Minkowski space and in Anti-de Sitter space. In the latter case we also compute an additional geometric contribution, which according to a recent proposal then collectively give the 1/N corrections to the entanglement entropy of the conformal field theory dual. We obtain some perturbatively exact results in both cases which illustrate monotonic interpolation between ultraviolet and infrared fixed points. This is consistent with recent work on the irreversibility of renormalization group, allowing some assessment of the aforementioned proposal for holographic entanglement entropy and illustrating the generalization of the g-theorem for boundary conformal field theory.

An exploration of the professional capital of authors who recontextualise knowledge about place in English A level geography textbooks

description: Initiated in 2014, A level curriculum reform in England was driven by the government’s desire to restore academic rigour, help bridge the school-academy divide and better prepare school leavers for the world of work, university and life in society. Reform provided the opportunity to revise A level textbooks and revive their position in the resource ecology of the classroom. Previous research on geography textbooks focuses on textbook perception and use, curriculum coverage and the representation of place. Yet, there is remarkably little research with the author, rather than textbook, as the central concern. My research fills this gap. Textbook authors are an important source of data. Drawing on communities of practice and their own accumulated knowledge and expertise, authors select, organise and transform knowledge created in the parent discipline (its methods, prevailing paradigm and knowledge) and society into a format that is appropriate for use at A level. As the discipline of geography is broad and multi-paradigmatic and the process of recontextualisation is complex, my research focuses on understanding the decisions authors make about place selection and knowledge. Place was selected as it is the most central of geographical concepts and a new core unit for the revised A level subject content. This idiographic case study research elicits the views of nine authors, with data generated using questionnaires, semistructured interviews and Q-sort. The latter is currently an under-used methodology in geography education research. By exploring themes developed through reflexive thematic analysis, findings suggest that authors draw on human, social and decisional capital developed through immersion in teaching, assessment and pedagogy. Furthermore, reflective practice is seen to play a key role in the recontextualisation of knowledge, helping authors to utilise opportunities and deal with constraints experienced during the writing process.

description: Objective: To examine differences in caregiver perceptions of task difficulty, depressive symptoms and life changes based on caregiver characteristics of gender, race and type of relationship to the person with stroke. Methods: A sample of 243 stroke caregivers (females n = 191; males n = 52; non-African Americans n = 184; African Americans n = 59; non-spouses n = 127; spouses n = 116) were interviewed by telephone within 8 weeks of the survivor’s discharge to home. Measures included the Oberst Caregiving Burden Scale (OCBS) for task difficulty, Patient Health Questionnaire (PHQ-9) for depressive symptoms and Bakas Caregiving Outcomes Scale (BCOS) for life changes. Three general linear models computed differences in OCBS, PHQ9 and OCBS scores. Results: Significant differences were found on the OCBS for females (p p p p = 0.047), spouses (p = 0.003) and African-American spouses (p = 0.010); and on the BCOS for females (p = 0.008) and non-African Americans (p = 0.033). Conclusions: Findings suggest that female and non-African American stroke caregivers are relatively more likely to experience task difficulty, depressive symptoms and negative life changes as a result of providing care. African American spouses were also at risk. Tailoring interventions based on caregivers’ characteristics may improve outcomes. Trial registration:ClinicalTrials.gov identifier: NCT01275495.

description: Saddle-point problems have recently gained an increased attention from the machine learning community, mainly due to applications in training Generative Adversarial Networks using stochastic gradients. At the same time, in some applications only a zeroth-order oracle is available. In this paper, we propose several algorithms to solve stochastic smooth (strongly) convex-concave saddle- point problems using zeroth-order oracles, and estimate their convergence rate and its dependence on the dimension n of the variable. In particular, our analysis shows that in the case when the feasible set is a direct product of two simplices, our convergence rate for the stochastic term is only by a log n factor worse than for the first-order methods. We also consider a mixed setup and develop 1/2th-order methods which use zeroth-order oracle for the minimization part and first-order oracle for the maximization part. Finally, we demonstrate the practical performance of our zeroth-order and 1/2th-order methods on practical problems.
Nonlinear Dynamics and Dissipation of a Curvilinear Vortex Driven by a Strong Time-Dependent Meissner Current

description: We report numerical simulations of large-amplitude oscillations of a trapped vortex line under a strong ac magnetic field $H(t)=H\sinωt$ parallel to the surface. The power dissipated by an oscillating vortex segment driven by the surface ac Meissner currents was calculated by taking into account the nonlinear vortex line tension, vortex mass and a nonlinear Larkin-Ovchinnikov (LO) viscous drag coefficient $η(v)$. We show that the LO decrease of $η(v)$ with the vortex velocity $v$ can radically change the field dependence of the surface resistance $R_i(H)$ caused by trapped vortices. At low frequencies $R_i(H) $ exhibits a conventional increases with $H$, but as $ω$ increases, the surface resistance becomes a nonmonotonic function of $H$ which decreases with $H$ at higher fields. The effects of frequency, pin spacing and the mean free path $l_i $ on the field dependence of $R_{i}(H) $ were calculated. It is shown that, as the surface gets dirtier and $l_i$ decreases, the anomalous drop of $ R_{i}(H) $ with $H$ shifts to lower fields which can be much smaller than the lower critical magnetic field. Our numerical simulations also show that the LO decrease of $η(v)$ with $v$ can cause a vortex bending instability at high field amplitudes and frequencies, giving rise to the formation of dynamic kinks along the vortex. Measurements of $R_i(H)$ caused by sparse vortices trapped perpendicular to the surface can offer opportunities to investigate an extreme nonlinear dynamics of vortices driven by strong current densities up to the depairing limit at low temperatures. The behavior of $R_i(H)$ which can be tuned by varying the rf frequency or concentration of nonmagnetic impurities is not masked by strong heating effects characteristic of dc or pulse transport measurements.

description: We have developed and tested a novel method, based on LIDAR, of measuring the height and profile of the mesospheric sodium layer using a continuous wave laser. It is more efficient than classical LIDAR as the laser is on for 50% of the time, and so can in principle be used during laser guide star adaptive optics observations. It also has significant advantages over direct imaging techniques because it does not require a second telescope, is almost independent of the atmospheric conditions, and avoids triangulation problems in determining the height. In the long term, regular monitoring using this method would allow a valuable database of sodium layer profiles, heights, and return flux measurements to be built up which would enable observatory staff astronomers to schedule observations optimally. In this paper we describe the original experiment carried out using the ALFA laser guide star system at Calar Alto Observatory in Spain. We validate the method by comparing the LIDAR results with those obtained from simultaneous imaging from an auxiliary telescope. Models are presented of a similar system to be implemented in the Very Large Telescope Laser Guide Star Facility, which will enable the initial focus setting for the adaptive optics systems to be determined with an accuracy of less than 200 m on a timescale of 1 minute.

description: Die Forschung ging bislang davon aus, dass Bismarck ein bedeutender Bestandteil von Hitlers Propaganda war. Dieser Beitrag kommt hingegen zu dem Ergebnis, dass Bismarck in den Äußerungen Hitlers nur eine untergeordnete Rolle gespielt hat. Das hatte zwei Gründe. Zum einen waren die dominierenden Bismarck-Mythen und Hitlers Ideologie zu großen Teilen inkongruent. Zum anderen versuchte Hitler den Nationalsozialismus als eine neue und dynamische politische „Bewegung“ erscheinen zu lassen und sich damit von den anderen Gruppierungen der Rechten, vor allem der DNVP, abzusetzen. Für die DNVP waren die Vergangenheit und Bismarck lange Zeit ein Leitbild. Dagegen war Hitler bemüht, vor allem die Zukunft zur wichtigsten Kategorie seiner Propaganda zu machen.
description: Research thus far has presumed that Bismarck was a crucial feature in Hitler’s propaganda. Conversely, this article reaches the conclusion that Bismarck merely played a subordinate role in Hitler’s remarks. There were two reasons for this. For one, the dominant Bismarck myths were largely incongruent with National Socialist ideology. Furthermore, Hitler sought to make National Socialism appear as a new and dynamic political „movement“ in an effort to distinguish it from other groupings on the right and the DNVP in particular. For the DNVP, the past and Bismarck were guiding principles, whereas Hitler strove to make the future the most important category of his propaganda.

description: The importance of Alpine ecosystems is increasing due to the influence of a wide number of ecological factors. Atmospheric attenuation of solar radiation, particularly in the ultraviolet spectra, is decreasing, leading to higher surface exposure and higher doses in plants and diurnal animals. At the same time, exposure to man-made radionuclides in the high mountains in Europe is decreasing due to the radioactive decay of anthropogenic radioisotopes, as well as the sedimentation and de-mobilization of heavier elements, which reduce exposure of the Alpine biota to technogenic emitters. The current article is based on biomonitoring studies of wild small mammals, conducted on Rila Mountain in the period 1993-2020. Total β-activity was measured with the use of a low-background beta counter (LAS 3A level activity system with 30% efficiency on 40K). A reduction by a factor of 10 was observed over a two-decade time period, attributable in part to the decay of deposited anthropogenic β-emitters after the Chernobyl accident in 1986. The highest reduction was observed in Apodemus sp., the least – in the herbivorous vole Myodes glareolus, indicating the high potential of the latter species as a zoomonitor of residual radioactive contamination. The comparative utility of several rodent taxa: Apodemus species, and two representatives of the subfamily Arvicolinae: M. glareolus and Chionomys nivalis and insectivorous Sorex araneus is discussed in the context of the radioecological biomonitoring of high mountain ecosystems. Finally, the study is put in the global context of climate change and overall increased anthropogenic pressure, affecting other ecosystems such as tundra and boreal forests.
title: Review of contemporary terminology for damaging surficial processes: stream flow, hyperconcentrated sediment flow, debris flow, mud flow, mud flood, mudslide

description: The term "mudslide" seems to be favored by news media for all localized processes in which damage is caused by moving earth materials, regardless of whether the processes involved mud or sliding. The term came into prominence sixty years ago when an atmospheric river moved over southern California with disastrous landslides, debris flows, and floods. Very costly floodlike damage resulting from "mudslides" was added to the National Flood Insurance Program coverage as a result of the 1969 disaster. Landslides were, and still are, excluded from the flood insurance program and other insurance instruments. Because of lack of clarity in what range of phenomena was intended to be covered by the flood insurance program, a panel of experts assembled by the National Research Council (NRC) categorized the continuum of moving water to moving earth into (1) clear-water floods, (2) mud floods, (3) mud flows, and (4) other landslides. These categories recognize the lack of clear distinction between slope-movement classifications and floodlike damage caused by more fluid "landslides." Earth materials in the most recent landslide classification are subdivided into rock and soil; soil is further subdivided into debris and earth. Debris is composed of mineral fragments with 20 to 80 percent coarser than sand size, whereas earth is 80 percent sand and finer fragments. Mud was used in older geology-based classifications in a way similar to earth (e.g., mudstone). Mud is not a technical term in engineering usage. Sediment-water mixtures with sufficient water to behave hydraulically were called mud floods by the NRC. Mud flows differ from mud floods by having viscoplastic behavior, which allow mud flows to support fragments with densities greater than water during transportation and when the mass comes to rest. Mud flows and debris flows have a velocity-dependent strength (matrix viscosity) and a velocity-independent strength (shearing resistance of the mass). As a mud flow or debris flow slows to a stop, the velocity-dependent strength goes to zero; however, dense fragments do not sink or settle into the mass because of its static shearing resistance. The deposits of this spectrum of processes have distinctive sedimentary structures: clear-water flood deposits are stratified, graded, and fining upward; debris-flow deposits are unsorted, unstratified, and fully matrix supported; hyperconcentrated-flow deposits are fully clast supported. Debris-flow deposits may contain megaclasts, if they are available in the source area. Geoscientists and engineers need to understand contemporary terms used in the media to communicate with emergency managers and a variety of non-specialists, but also should recognize characteristics that are associated with specialized technical terms.

description: We show that sums of carefully chosen coincidence rates in a multiphoton interferometry experiment can be simplified by replacing the original unitary scattering matrix with a coset matrix containing $0$s. The number and placement of these $0$s reduces the complexity of each term in the sum without affecting the original sum of rates. In particular, the evaluation of sums of modulus squared of permanents is shown to turn in some cases into a sum of modulus squared of determinants. The sums of rates are shown to be equivalent to the removal of some optical elements in the interferometer.

Queer Atmospheres

description: There exists an overlap between the work of Queer Aesthetics and Queer Ecology, specifically across the realm of naturalization. Long has nature been the realm of the Queer. However, in the Anthropocene, the natural ceases to exist as it once did apart from the artifice of human kind. Or, in the words of Donatella Versace, when asked if she would ever return to her natural hair colour, “Natural? What is natural?” If we exist in an epoch where the natural ceases to exist, where is the is the future of queer space? Between the work of Queer Ecology and Queer Aesthetics lies a common interest in negative space. In landscape architecture, the most ubiquitous and yet unseen negative space of all is the atmosphere. And, in atmospheric design, sensile experience joins bodies across spaces. Towards sensory entanglement, this graduate project proposes two bathing spaces in Squamish and on Mount Meager, pairing pleasure with an experience of a thickened edge between the water and air. This proposal seeks to design for the humidity in the atmosphere as a means to cultivate care for the unseen.

description: Miller, Stibich and Moore (2010) developed a set-valued coarse invariant $σ\left(X,ξ\right)$ of pointed metric spaces. DeLyser, LaBuz and Tobash (2013) provided a different way to construct $σ\left(X,ξ\right)$ (as the set of all sequential ends). This paper provides yet another definition of $σ\left(X,ξ\right)$. To do this, we introduce a metric on the set $S\left(X,ξ\right)$ of coarse maps $\left(\mathbb{N},0\right)\to\left(X,ξ\right)$, and prove that $σ\left(X,ξ\right)$ is equal to the set of coarsely connected components of $S\left(X,ξ\right)$. As a by-product, our reformulation trivialises some known theorems on $σ\left(X,ξ\right)$, including the functoriality and the coarse invariance.

description: With a new joint-deconvolution pipeline, we combine the single-dish and interferometric atomic hydrogen (HI) data of M51 observed by the Five-hundred-meter Aperture Spherical radio Telescope (FAST) (FEASTS program) and the Very Large Array (VLA) (THINGS). The product data cube has a typical line width of $13\,\text{km}\,\text{s}^{-1}$ and a $2σ$ line-of-sight (LOS) sensitivity of HI column density $N_\text{HI}\sim3.2\times10^{18}\,\text{cm}^{-2}$ at a spatial resolution of ${\sim}18''$ (${\sim}0.7\,\text{kpc}$). Among the HI-detected LOSs extending to ${\sim}50\,\text{kpc}$, ${\sim}89\%$ consist of diffuse HI only, which is missed by previous VLA observations. The distribution of dense HI is reproduced by previous hydrodynamical simulations of this system, but the diffuse component is not, likely due to unresolved physics related to the interaction between the circumgalactic and interstellar media. With simple models, we find that these low-$N_\text{HI}$ structures could survive the background ultraviolet photoionization, but are susceptible to the thermal evaporation. We find a positive correlation between LOS velocity dispersion ($σ_v$) and $N_\text{HI}$ with a logarithmic index of ${\sim}0.5$. Based on existing turbulent mixing layer (TML) theories and simulations, we propose a scenario of hot gas cooling and accreting onto the disk through a TML, which could reproduce the observed power index of ${\sim}0.5$. We estimate the related cooling and accretion rates to be roughly one-third to two-thirds of the star-formation rate. A typical column density of diffuse HI (${\sim}10^{19}\,\text{cm}^{-2}$) can be accreted within $300\,\text{Myr}$, the interaction time scale previously estimated for the system. Such a gas accretion channel has been overlooked before, and may be important for gas-rich interacting systems and for high redshift galaxy evolution.

description: We have measured the specific heat and magnetization {\it versus} temperature in a single crystal sample of superconducting La$_{2}$CuO$_{4.11}$ and in a sample of the same material after removing the excess oxygen, in magnetic fields up to 15 T. Using the deoxygenated sample to subtract the phonon contribution, we find a broad peak in the specific heat, centered at 50 K. This excess specific heat is attributed to fluctuations of the Cu spins possibly enhanced by an interplay with the charge degrees of freedom, and appears to be independent of magnetic field, up to 15 T. Near the superconducting transition $T_{c}$($H$=0)= 43 K, we find a sharp feature that is strongly suppressed when the magnetic field is applied parallel to the crystallographic c-axis. A model for 3D vortex fluctuations is used to scale magnetization measured at several magnetic fields. When the magnetic field is applied perpendicular to the c-axis, the only observed effect is a slight shift in the superconducting transition temperature.

We analyse the D-branes geometry. We compute open and closed string scattering amplitudes in the presence of the D-branes and discuss the results. We find that, except the space filling D-branes, the B-type D-branes decouple from the bulk. The A-type D-branes exhibit inconsistency. We construct the D-branes effective worldvolume theories. They are given by a dimensional reduction of self-dual Yang-Mills theory in four dimensions. We construct the D-branes gravity backgrounds. Finally, we discuss possible N=2 open/closed string dualities.

description: (abridged) We present the first study that combines binary population synthesis in the Galactic disk and detailed evolutionary calculations of low- and intermediate-mass X-ray binaries (L/IMXBs). We show that the formation probability of IMXBs with initial donor masses of 1.5--4 Msun is typically >~5 times higher than that of standard LMXBs, and suggest that the majority of the observed systems may have descended from IMXBs. Distributions at the current epoch of the orbital periods, donor masses, and mass accretion rates have been computed, as have orbital-period distributions of BMPs. Several significant discrepancies between the theoretical and observed distributions are discussed. The orbital-period distribution of observed BMPs strongly favors cases where the envelope of the neutron-star progenitor is more easily ejected during the common-envelope phase. However, this leads to a >~100-fold overproduction of the theoretical number of luminous X-ray sources relative to the total observed number of LMXBs. X-ray irradiation of the donor star may result in a dramatic reduction in the X-ray active lifetime of L/IMXBs, thus possibly resolving the overproduction problem, as well as the long-standing BMP/LMXB birthrate problem.

description: This white paper proposes leveraging high-quality Gaia data available to the worldwide scientific community and complement it with support from Canadian-related facilities to place Canada as a leader in the fields of stellar associations and exoplanet science, and to train Canadian highly qualified personnel through graduate and post-graduate research grants. Gaia has sparked a new era in the study of stellar kinematics by measuring precise distances and proper motions for 1.3 billion stars. These data have already generated more than 1700 scientific papers and are guaranteed to remain the source of many more papers for the upcoming decades. More than 900 new age-calibrated young low-mass stars have already been discovered as a direct consequence of the second Gaia data release. Some of these may already be host stars to known exoplanet systems or may become so with the progress of the TESS mission that is expected to discover 10,000 nearby transiting exoplanets in the upcoming decade. This places Canada in a strategic position to leverage Gaia data because it has access to several high-resolution spectrometers on 1-4 m class telescopes (e.g. The ESPaDOnS, SPIRou and NIRPS), that would allow to quickly characterize this large number of low-mass stars and their exoplanet systems. This white paper describes the opportunity in such scientific projects that could place Canada as a leader in the fields of stellar associations and exoplanets.

description: Algebraic approach to the integrability condition called shape invariance is briefly reviewed. Various applications of shape-invariance available in the literature are listed. A class of shape-invariant bound-state problems which represent two-level systems are examined. These generalize the Jaynes-Cummings Hamiltonian. Coherent states associated with shape-invariant systems are discussed. For the case of quantum harmonic oscillator the decomposition of identity for these coherent states is given. This decomposition of identity utilizes Ramanujan's integral extension of the beta function.

description: Relationships between circulating immune mediators (cytokines, chemokines and growth factors) and a beta cell destructive autoimmune process in adult-onset type 1 diabetes are poorly elucidated. We measured serum levels of immune mediators in type 1 diabetic patients in the context of ongoing deterioration of endogenous insulin secretion. Levels of 27 immune mediators were measured in 34 GADA (glutamic acid decarboxylase antibodies) positive type 1 diabetic patients, aged 27.4 ± 1.2 years at a mean of 7 weeks after diagnosis (designated 0 month) and 6 months later. Endogenous insulin secretion was assessed by C-peptide glucagon stimulation tests during 12 months. Additional data (for baseline analysis) was obtained in 9 GADA positive type 1 diabetic subjects and in 43 non-diabetic age- and sex-matched subjects. In general, the levels of immune mediators displayed large inter- but small intra-individual differences with only minor changes observed between measurements at 0 month and at 6 months. Levels of the majority of immune mediators were strongly and positively correlated to each other not only in the diabetic, but also in the non-diabetic subjects. Body weight (BMI) was positively associated with levels of IL-1 ra, IL-2, IL-4, IL-6, IL-17, Basic FGF, GCSF, IFN gamma and MIP-1 alpha. Adjustment for BMI removed most associations to C-peptide. When adjusted for BMI, levels at 0 month for Basic FGF and MIP-1 alpha were inversely associated with the percentage decline in stimulated C-peptide from 0 to 12 months (nominally p Trial registration:ClinicalTrials.gov identifier: NCT00131755.

description: Following the recent advances in deep networks, object detection and tracking algorithms with deep learning backbones have been improved significantly; however, this rapid development resulted in the necessity of large amounts of annotated labels. Even if the details of such semi-automatic annotation processes for most of these datasets are not known precisely, especially for the video annotations, some automated labeling processes are usually employed. Unfortunately, such approaches might result with erroneous annotations. In this work, different types of annotation errors for object detection problem are simulated and the performance of a popular state-of-the-art object detector, YOLOv3, with erroneous annotations during training and testing stages is examined. Moreover, some inevitable annotation errors in CVPR-2020 Anti-UAV Challenge dataset is also examined in this manner, while proposing a solution to correct such annotation errors of this valuable data set.

description: Seasonal patterns in production and demand are common in many agricultural markets. Charting these patterns provides information that complements fundamental and technical analyses. It is in this spirit that this paper seeks to examine price seasonality in the catfish value chain in Uganda. The analysis draws on monthly prices taken from secondary source recorded data and uses moving average index to chart price patterns. The results reveal distinct seasonal patterns in the farm-gate, ex-vessel, retail, and wholesale market channels. Across market channels, the results for farm-gate versus ex-vessel prices reveal that farm-gate prices are more affected by seasonal effects compared to ex-vessel prices. On the contrary, both price series in the retail versus wholesale market channels show a declining trend, with the wholesale price series showing stronger variability compared to the retail price series.

description: The primary objective of the study was to examine determinants of consumer preferences for and expenditure on rice in the Kilimanjaro Region, Tanzania. Data were collected from a random sample of 230 participants, and analyzed using descriptive statistics and regression analyses. The descriptive statistics revealed that domestic rice was preferred by a majority of the participants over imported rice. The most important attribute for consumers was aroma, followed by taste, cleanness, and price. The logistic regression analysis showed that price of a substitute, quality, and household size had significant effects on preference for rice, domestic or imported. The OLS analysis revealed that the price of rice, income, frequency of consumption, and household size had significant effects on expenditure on rice. It is suggested that domestic rice should be promoted, and influential factors should be considered in any consumption and policy changes in the rice industry.

description: Drugs at ultra-high dilutions close to the Avogadro´s number (theoretical 0-molarity is 10-24) and without apparently containing any drug molecule, have been used in homeopathy therapy for about two centuries. Nowadays, homeopathic procedures involving the controversial phenomenon called “water memory”, have regained their use in different application areas. In the present study, 10-7, 10-14, and 10-36 dilutions of a commercial fertilizer were evaluated in a 7-day wheat growth bioassay. Test dilutions were prepared following a standardized protocol, according to the method of stepwise dilution and succession, as derived from traditional homeopathy. Experiments were performed on herbicides- and pesticides-free wheat grains (Triticum durum Rafi C97 variety). Treatments were compared with negative controls including; a) pure bi-distilled water and b) sham-treated pure bi-distilled water, following the same protocol as used for fertilizer dilutions with 200 strokes and the same steps of dilutions. A 2% of commercial fertilizer was used as a positive control. The observed results of three independent bioassays, showed an increased wheat stalk growth after treatment with diluted and agitated fertilizer solutions, as compared with negative controls (p < 0.05). Positive controls showed the highest stalk growth, but it was not significantly different from that of the diluted fertilizer. These results suggest that there was an influence of highly diluted commercial fertilizer on wheat seedling development.

description: Neuromyelitis optica (NMO) and multiple sclerosis (MS) are autoimmune demyelinating diseases of the central nervous system. The discovery of NMO immunoglobulin G (NMO-IgG) antibody has improved the clinical definition of NMO. Recently, the autophagy-related genes (ATGs) have been proved to be associated with several autoimmune and inflammation diseases. Increased T cell expression of ATG5 may be correlated with the pathogenesis of inflammatory demyelination in MS. However, the association of ATG5 variants with MS and NMO patients has not been well studied. In this study, five ATG5 variants were genotyped in 144 MS patients, 109 NMO patients and 288 controls in the Han Chinese population. In the cohort of NMO patients, we observed that the CC genotype of rs548234 increased susceptibility to NMO (p = 0.016), while the allele T of rs548234 (p = 0.003) and the allele A of rs6937876 (p = 0.009) acted as protective factors for NMO-IgG positive NMO patients. However, no association was found between ATG5 variants and MS patients. These results indicated that ATG5 variants are associated with NMO but not MS patients, which may provide a clue for further clarifying the autoimmune mechanisms of autophagy-related pathogenesis in NMO.
