description: Bundling agricultural insurance with climate-smart technologies and practices (CSA) can help improve risk management for smallholder farmers. This paper analyzes how bundling affects demand for insurance and CSA. Calibrating index insurance parameters to CSA payoff profiles increases the demand for insurance, but only when basis risk is low, and these effects of reducing basis risk itself. This raises the question how to bundle insurance products that leverage new technologies to provide indemnity insurance coverage with minimal basis risk. We therefore study the effect of bundling indemnity insurance with CSA technologies. Specifically, in a field experiment in India, we test whether conditioning insurance payouts on not burning residues improves residue management as a CSA technology. We find that this is the case, suggesting that indemnity insurance can help promote CSA technology adoption, but we also discuss shortcomings of this bundling approach, and identify potential alternatives to combine indemnity insurance and CSA technologies into a complementary risk management bundle.

description: Notwithstanding improvements over the last several decades, food and nutrition insecurity is still widespread and progresses made have been uneven. In Africa, the central and western parts scored the lowest and highest reduction in malnutrition, respectively. This regional heterogeneity is expected given the spatial variation in (inclusive) economic growth, agro-ecology, market access, the prevalence of diseases and infections, as well as institutional and policy environments (e.g., social protection systems) that affect the various dimensions of food and nutrition security. At the same time, climatic and weather changes are expected to worsen in the coming decades with potentially devastating effects in the region, given its heavily relies on rain-fed agriculture and the market and institutional failures that limit the set of coping and adaptation strategies. This study examines the linkages between climatic shocks and child undernutrition in the diverse farming systems of Africa. We examine effects of climatic changes not only through yields (agricultural mechanism) but also through vector-borne and gastrointestinal diseases (health mechanism). Preliminary results suggest significant heterogeneity in the incidence of child undernutrition and the effects of climatic shocks by agro-ecology and farming systems, meriting further investigation we are currently undertaking to disentangle the role of each mechanism.

description: We report the identification of cyclical changes in the orbital period of the eclipsing dwarf novae V2051 Ophiuchi and V4140 Sagitarii. We used sets of white dwarf mid-eclipse timings to construct observed-minus-calculated diagrams covering, respectively, 25 and 16 years of observations. The V2051 Oph data present cyclical variations that can be fitted by a linear plus sinusoidal function with period 22 +/- 2 yr and amplitude 17 +/- 3 s. The statistical significance of this period by an F-test is larger than 99.9 per cent. The V4140 Sgr data present cyclical variations of similar amplitude and period 6.9 +/- 0.3 yr which are statistically significant at the 99.7 per cent level. We derive upper limits for secular period changes of |dP/dt| < 3x10^{-12} and |dP/dt| < 1.8x10^{-11}, respectively for V2051 Oph and V4140 Sgr. We combined our results with those in the literature to construct a diagram of the amplitude versus period of the modulation for a sample of 11 eclipsing cataclysmic variables (CVs). If the cyclical period changes are the consequence of a solar-type magnetic activity cycle in the secondary star, then magnetic activity is a widespread phenomenon in CVs, being equally common among long- and short-period systems. This gives independent evidence that the magnetic field (and activity) of the secondary stars of CVs do not disappear when they become fully convective. We also find that the fractional cycle period changes of the short-period CVs are systematically smaller than those of the long-period CVs.

description: The current study brought together climate change and the COVID-19 pandemic. Most of the previous literature done about the pandemic relates to mental well-being, not taking into account the effect of the pandemic on behaviours that can affect climate change (Cénat et al., 2020; Li, Fu, Fan, Zhu, & Li, 2021; Yamamoto, Uchiumi, Suzuki, Yoshimoto, & Murillo-Rodriguez, 2020). In specific, this study analyzed the effect of the COVID-19 Pandemic on the University of British Columbia’s staff member’s climate-friendly behaviour. We previously predicted that the high-stress environment created by the pandemic would decrease UBC staff members’ climate-friendly behaviour. There were three different time frames for staff members: pre-pandemic, present pandemic and post-pandemic. A questionnaire measured five different climate-friendly behaviours: driving of personal vehicles, flying, energy conservation at home, single-use plastic items and eating animal products. 58 participants completed this survey. A two-ANOVA analysis revealed significance for the climate-friendly behaviours decreasing in the post-pandemic condition. Although further analysis using a Post Hoc Holm test revealed that significance consisted only in flying behaviour in post-pandemic condition. This was even more prevalent in the time conditions: pandemic to post-pandemic.

description: Topological wave structures, such as vortices and skyrmions, appear in a variety of quantum and classical wave fields, including optics and acoustics. In particular, optical vortices have found numerous applications ranging from quantum information to astrophysics. Furthermore, both optical and acoustic structured waves are crucial for manipulation of small particles, from atoms to macroscopic biological objects. Here we report on the controllable generation of topological structures -- wave vortices, skyrmions, and polarization Möbius strips -- in interfering gravity water waves. Most importantly, we demonstrate efficient manipulation of subwavelength and wavelength-order floating particles with topologically structured water waves. This includes trapping of the particles in the high-intensity field zones, as well as controllable orbital and spinning motions due to the orbital and spin angular momenta of water waves. Our results reveal the water-wave counterpart of optical and acoustic manipulations, which paves the avenue for applications in hydrodynamics and microfluidics.

description: Неврахування інтеграційних ризиків у проєкті створення логістичного комплексу, що характеризується великою кількістю учасників, які змінюються протягом життєвого циклу проєкту, може стати однією з причин зниження успішності реалізації проєкту, навіть призвести до його припинення. Для запобігання інтеграційних ризиків необхідно провести аналіз ризиків, що враховує інтеграційний потенціал учасників проєкту. Визначено поняття «інтеграційного проєктного ризику». А також розроблено послідовність аналізу інтеграційних ризиків у проєкті створення логістичного комплексу, яка полягає у використанні методів менеджменту якості, а саме: аналізу Парето, АВС-аналізу та причинно-наслідкового аналізу Ісікави. Застосування методів якісного аналізу здійснюється у логічній послідовності. Вихідні дані, що отримані при проведенні попереднього виду аналізу, є вхідними для наступного етапу дослідження. Отримані результати дають змогу на початковій стадії проєкту збільшити вплив на його результати завдяки зниженню ступеня інтеграційних ризиків. Зокрема, аналіз Паретота АВС-аналіз допомагають виділити учасників проєкту, що мають найбільшу кількість інтеграційних зв’язків. Оцінювання потужностей інтеграційних зв’язків та визначення інтеграційного потенціалу учасника проєкту допомагає визначити найбільш уразливого до ризику розриву інтеграційних зв’язків учасника. Отже, вихід такого учасника з проєкту принесе найбільші порушення інтеграції між елементами системи. Причинно-наслідковий аналіз Ісікави дає змогу виявити причини розриву інтеграційних зв’язків між учасниками проєкту та визначити найменш потужні інтеграційні зв’язки між учасниками. Це допоможе вжити заходи для попередження настання інтеграційних ризиків у проєкті створення логістичного центру.

description: In the context of an inflationary Randall-Sundrum Type II braneworld (RS2) we calculate spectral indices and amplitudes of cosmological scalar and tensor perturbations, up to second order in slow-roll parameters. Under very simple assumptions, extrapolating next-order formulae from first-order calculations in the case of a de Sitter brane, we see that the degeneracy between standard and braneworld lowest-order consistency equations is broken, thus giving different signatures of early-universe inflationary expansion. Using the latest results from WMAP for estimates of cosmological observables, it is shown that future data and missions can in principle discriminate between standard and braneworld scenarios.

description: This proposal aims to estimate the incidence of fish meal basis diet into the total farm cost structure and how the weight can change considering different hypotheses related to introduction of insect meal into the diet. Hypotheses were proposed on the basis of increasing levels of insect meal into the diet and different prices for purchasing this meal. Economic effects were simulated according to some empirical trials carried out into the scientific literature and were applied to the European sea bass farming. A case study approach on a specialized off-shore sea bass farm in Italy was proposed. It is a small-scale farm that solely produce for local and domestic market. Findings suggest that feeding cost amounts to about 63% of the total farm cost. Possible introduction of insect meal – specifically composed by Tenebrio molitor basis – would force farmers to increase feeding cost. As it stands today, higher environmental sustainability expected by inclusion of insect meal would not be gone with more economic convenience. However technological development, higher competition into the insect meal industry, increase of production scale, and adoption of strategies aimed to weaken bargaining power between fish farmers and meal suppliers could generate a price decrease.

description: Extensions of the Standard Model of elementary particle physics to noncommutative geometries have been proposed as a low energy limit of string models. Independent of this motivation, one may consider such a model as an effective field theory with higher-dimensional operators containing an antisymmetric rank-two background field. We study the signals of such a Noncommutative Standard Model (NCSM) and analyze the discovery potential of a future photon collider, considering angular distributions in fermion pair production.

description: Geodesics in general relativity describe the behaviour of test particles in a gravitational field. In 5D Kaluza-Klein, geodesics reproduce the Lorentz force motion of particles in an electromagnetic field. This paper studies geodesic motion on a higher-dimensional $M_4 \times K$ with background metrics encoding general 4D gauge fields and Higgs-like scalars. It shows that the classical mass and charge of a test particle become variable quantities when the geodesic traverses regions of spacetime with massive gauge fields, such as the weak force field, or with non-constant Higgs scalars. This agrees with the physical fact that interactions mediated by massive bosons can change the mass and charge of particles. The variation rates of mass and charge along a geodesic are given by natural geometric formulae. In regions where mass is preserved, there are additional constants of motion, one for every abelian or simple summand in the Killing algebra of $K$. The last part of the paper discusses traditional difficulties of Kaluza-Klein models, such as the low $q / m$ ratios in the 5D model. It suggests possible ways to circumvent them. It also remarks the naturalness of a model in which elementary particles always travel at the speed of light in higher dimensions.

description: The large difference between the producer price of a beef carcass and the retail prices of individual beef cuts raised concerns among producers. Producers believe that they were carrying all the risk and that retailers fixed their prices, irrespective of the market price at that stage. This study examines the price transmission mechanisms in the Bloemfontein beef market using the producer price and retail prices at four retail outlets collected over a period of 3 years. It further estimates the causality links between the producer and retail prices. The traditional (Engle-Granger) and standardized (Enders & Siklos) Augmented Dickey- Fuller procedures were used to test for co-integration and asymmetry in price transmission. Four competing models, namely, Engle-Granger, Threshold Autoregressive , Momentum Threshold Autoregressive, and Momentum Consistent TAR models were applied. The following results were found: asymmetric price transmission between producer and retail prices, the results on the flow of market information indicated that a flow of market information did exist in the markets of three of the four retailers. The price transmission relationship of two of the retailers are beneficial to the consumers, as the marketing margin declined over time, while the relationship of the other two retailers are detrimental to consumers.

Publisher: name: The Open University
Year: 1985

description: Toates and Oatley (1970) presented a computer simulation of rat body fluid dynamics. Whilst their two- compartment (intracellular and extracellular) model was a significant contribution, it does not adequately represent cardiovascular, renal or hormonal aspects of water metabolism. Two models are presented. The simpler model ('small rat') was designed to meet educational criteria, whilst the more complex model ('large rat') is more research-oriented. Both supercede existing models, but the large rat is the more detailed representation. Both are three-compartment models- intracellular, interstitial and vascular. The cardiovascular system is well represented; this has permitted the realistic simulation of many renal, neuronal and endocrine systems important to water homeostasis. Many other related systems are also described, such as the gastro-intestinal tract, energy balance, insensible water loss and electrolyte metabolism in each of the body compartments. The inclusion of such systems has permitted analyses of the 'volemic' (extracellular) drinking stimuli, and their interactions with other stimuli. The concept of redundancy in drinking stimuli is examined, and a new theory presented that permits its inclusion in current drinking models. The functional significance of central osmoreceptor siting is discussed, in the light of simulations of fluid absorption dynamics following drinking. Simulations of drinking responses following deprivation are studied. The results indicate an explanation for 'voluntary dehydration', in which water-deprived rats do not restore fluid balance to pre-deprivation levels when subsequently offered water. The inclusion of 'peripheral' drinking stimuli in the 'small rat' has enabled an analysis of such phenomena as sham drinking. The nature of the intracellular stimulus to thirst is examined, and a new energy-based theory is presented, which promises to resolve many apparent paradoxes. Finally, potential improvements and future developments are discussed.

However, gsreg is the first code that 1) guarantees optimality with out-of-sample selection criteria; 2) allows residual testing for each alternative; and 3) provides (depending on user specifications) a full-information dataset with outcome statistics for every alternative model.

Thereafter, a new design framework is described, which optimizes the polyphase code and corresponding mismatched filter, using a cost/error function, especially for weather radars. It establishes the performance of these intra-pulse techniques with specific application towards second trip removal.

description: We show how work can be extracted from number-state coherence in a two-mode Bose-Einstein condensate. With careful tuning of parameters, a sequence of thermodynamically reversible steps transforms a Glauber coherent state into a thermal state with the same energy probability distribution. The work extracted during this process arises entirely from the removal of quantum coherence. More generally, we characterise quantum (from coherence) and classical (remaining) contributions to work output, and find that in this system the quantum contribution can be dominant over a broad range of parameters. The proportion of quantum work output can be further enhanced by squeezing the initial state. Due to the many-body nature of the system, the work from coherence can equivalently be understood as work from entanglement.

description: Website owners make conscious and unconscious decisions that affect their users, potentially exposing them to privacy and security risks in the process. In this paper we introduce PrivacyScore, an automated website scanning portal that allows anyone to benchmark security and privacy features of multiple websites. In contrast to existing projects, the checks implemented in PrivacyScore cover a wider range of potential privacy and security issues. Furthermore, users can control the ranking and analysis methodology. Therefore, PrivacyScore can also be used by data protection authorities to perform regularly scheduled compliance checks. In the long term we hope that the transparency resulting from the published assessments creates an incentive for website owners to improve their sites. The public availability of a first version of PrivacyScore was announced at the ENISA Annual Privacy Forum in June 2017.

description: We present a power spectrum analysis of the ALMA Spectroscopic Survey Large Program (ASPECS LP) data from 84 to 115 GHz. These data predominantly probe small-scale fluctuations ($k=10$-$100$ h Mpc$^{-1}$) in the aggregate CO emission in galaxies at $1 \lesssim z \lesssim 4$. We place an integral constraint on CO luminosity functions (LFs) in this redshift range via a direct measurement of their second moments in the three-dimensional (3D) auto-power spectrum, finding a total CO shot noise power $P_{\textrm{CO,CO}}(k_{\textrm{CO(2-1)}}) \leq 1.9\times10^2$ $μ$K$^2$ (Mpc h$^{-1}$)$^3$. This upper limit ($3σ$) is consistent with the observed ASPECS CO LFs in Decarli et al. 2019, but rules out a large space in the range of $P_{\textrm{CO,CO}}(k_{\textrm{CO(2-1)}})$ inferred from these LFs, which we attribute primarily to large uncertainties in the normalization $Φ_*$ and knee $L_*$ of the Schechter-form CO LFs at $z > 2$. Also, through power spectrum analyses of ASPECS LP data with 415 positions from galaxies with available optical spectroscopic redshifts, we find that contributions to the observed mean CO intensity and shot noise power of MUSE galaxies are largely accounted for by ASPECS blind detections, though there are $\sim20$% contributions to the CO(2-1) mean intensity due to sources previously undetected in the blind line search. Finally, we sum the fluxes from individual blind CO detections to yield a lower limit on the mean CO surface brightness at 99 GHz of $\langle T_{\textrm{CO}} \rangle = 0.55\pm0.02$ $μ$K, which we estimate represents $68$-$80$% of the total CO surface brightness at this frequency.

description: We theoretically study hydrodynamic phenomena originating from electron-electron collisions in a two-dimensional Fermi system. We demonstrate that an electron beam sweeping past an aperture creates a pumping effect, attracting carriers from this aperture. This pumping effect originates from the specific electric potential distribution induced by the injected electrons. In the regions nearby the main stream of injected electrons, a positive potential is induced by the injected electrons. Thus, the normally repulsive Coulomb interaction leads to an attractive force in the Fermi system. This quantum pumping mechanism in a Fermi system differs qualitatively from the Bernoulli pumping effect in classical liquids. We also discuss possible experimental realizations.

description: We study the phenomenology of simplified $Z^\prime$ models with a global $U(2)^3$ flavour symmetry in the quark sector, broken solely by the Standard Model Yukawa couplings. This flavour symmetry, known as less-minimal flavour violation, protects $ΔF=2$ processes from dangerously large new physics (NP) effects, and at the same time provides a free complex phase in $b\to s$ transitions, allowing for an explanation of the hints for additional direct CP violation in kaon decays ($ε^\prime/ε$) and in hadronic $B$-decays ($B\to Kπ$ puzzle). Furthermore, once the couplings of the $Z^\prime$ boson to the leptons are included, it is possible to address the intriguing hints for NP (above the 5$\,σ$ level) in $b\to s \ell^+\ell^-$ transitions. Taking into account all flavour observables in a global fit, we find that $ε^\prime/ε$, the $B\to Kπ$ puzzle and $b\to s \ell^+\ell^-$ data can be explained simultaneously. Sizeable CP violation in $b\to s \ell^+\ell^-$ observables, in particular $A_8$, is predicted, which can be tested in the near future, and an explanation of the $B\to Kπ$ and $ε^\prime/ε$ puzzles leads to effects in di-jet tails at the LHC, that are not far below the current limits. Once $b\to s \ell^+\ell^-$ is included, cancellations in di-muon tails, possibly by a second $Z^\prime$, are required by LHC data.

Cracticus hypoleucus intermedius Mathews, 1912a: 373 (New South Wales).
Now considered an intergrade between Gymnorhina tibicen tyrannica and G. t. tibicen or undifferentiated from them. See Amadon, 1951: 21–22; 1962b: 169; Schodde and Mason, 1999: 545–550; Hughes et al., 2001: 25–34; Dickinson, 2003: 463; Toon et al., 2003: 337– 343; 2007: 2525–2547; and Russell and Rowley, 2009: 339–340.
HOLOTYPE: AMNH 673093, adult male, collected at Cooma, 36.15S, 149.07E (Times Atlas), New South Wales, Australia, in June 1896, by an unknown collector. From the Mathews Collection (no. 7067) via the Rothschild Collection.
COMMENTS: In the original description, Mathews cited his catalog number of the holotype and gave the type locality and the range as ‘‘ New South Wales.’’ The holotype bears the collecting locality ‘‘Cooma’’ on the original label. In addition the specimen bears Mathews and Rothschild type labels and a Mathews ‘‘Figured’’ label, indicating that the specimen was the model for Mathews (1923b: pl. 483, lower fig., opp. p. 337; text p. 351). In treating this form, Mathews placed it in a separate species, Gymnorhina hypoleuca, and noted that the above specimen was the type of intermedius. However, the species in the plate is labeled G. leuconota. Paratypes are: Bathurst, AMNH 673090 (Mathews no. 7068), male, May 1893, AMNH 673091 (7069), female, May 1883; Cooma, AMNH 673092 (7066), male, June 1896; New South Wales, AMNH 673096 (2564), male, December 1889, AMNH 673097 (2563), male, undated. Collectors of these specimens are unknown.
For a discussion of the identity of the type of intermedius, see Schodde and Mason (1999: 548). Hughes et al. (2001) and Toon et al., (2003, 2007) found no differentiation among this form, G. t. tibicen and G. t. tyrannica in selected DNA sequences.

description: Barthel, Royston, and Parmar (2009, Stata Journal 9: 505–523) presented a menu-driven Stata program for calculating sample size and other design characteristics for a class of multiarm, multistage trials with time-to-event outcomes. In this article, we present several new features for the package. First, we allow hazard ratios greater than 1 to be targeted under the alternative hypothesis to make the design more widely applicable to other outcomes and disease areas. Second, we introduce new subroutines that use simulation to more accurately estimate the correlation between treatment effects at different stages and that calculate the familywise error rate, and we apply them to an example using the original design of the multiarm, multistage trial in prostate cancer. Finally, we present a new design of the dialog menu for nstage that improves its usability and incorporates options for calling the new subroutines.

description: This paper presents the conceptual design of a low-cost simple printer head for Braille embossers. Such device consists of a set of three rotary cam-follower mechanisms that, upon actuation, produce deformation on paper. The set of cam-followers is actuated by a single servomotor which rotation determines which cam-follower strikes the paper. Braille characters are quickly embossed by column using the proposed system. The aim of this research is to provide new actuation ideas for making Braille embossers more affordable.

description: We have detected strong dichroism in the Ni $L_{2,3}$ x-ray absorption spectra of monolayer NiO films. The dichroic signal appears to be very similar to the magnetic linear dichroism observed for thicker antiferromagnetic NiO films. A detailed experimental and theoretical analysis reveals, however, that the dichroism is caused by crystal field effects in the monolayer films, which is a non trivial effect because the high spin Ni $3d^{8}$ ground state is not split by low symmetry crystal fields. We present a practical experimental method for identifying the independent magnetic and crystal field contributions to the linear dichroic signal in spectra of NiO films with arbitrary thicknesses and lattice strains. Our findings are also directly relevant for high spin $3d^{5}$ and $3d^{3}$ systems such as LaFeO$_{3}$, Fe$_{2}$O$_{3}$, VO, LaCrO$_{3}$, Cr$_{2}$O$_{3}$, and Mn$^{4+}$ manganate thin films.

European Market for Mercosur Agricultural Exports: An econometric study of commodity trade flows

description: The European Union (EU), which represents one of the world’s largest markets for raw materials and agricultural products, with imports of more than €113 billion in 2015, is a particularly attractive and very sought-after market for Mercosur exporters. This paper provides new evidence on income and price elasticities of demand for agricultural exports from Mercosur countries to the EU. The econometric analysis of the study is conducted with a sample of annual data which covers Mercosur’s major commodity exports to the EU from 1988 to 2015.The results indicate that for the eight commodities analysed there is a relatively weak demand response to income and price changes in the EU. The policy implication is that trade policy measures in the form of tariff and non-tariff barriers are not very significant in changing the quantity of imports demanded. However, the results suggest that relative-price variations affect significantly the demand for Mercosur agricultural exports, implying that the exporter’s market share is influenced by price competitiveness.

description: In this article, I describe a command, ipdmetan, that facilitates twostage individual participant data meta-analysis of any measure of effect and its standard error by fitting a specified model to data from each study. The command can estimate random effects and heterogeneity statistics and include additional covariates and interactions. If individual participant data are available for certain studies and aggregate data for others, ipdmetan allows them to be combined in one analysis. This command can produce detailed and flexible forest plots, including ones outside the context of formal meta-analysis.

description: Let $Λ$ be an artin algebra and $\mathcal{M}$ be an n-cluster tilting subcategory of $Λ$-mod with $n\ge 2$. From the viewpoint of higher homological algebra, a question that naturally arose in [17] is when $\mathcal{M}$ induces an n-cluster tilting subcategory of $Λ$-Mod. In this paper, we answer this question and explore its connection to Iyama's question on the finiteness of n-cluster tilting subcategories of $Λ$-mod. In fact, our theorem reformulates Iyama's question in terms of the vanishing of Ext; and highlights its relation with the rigidity of filtered colimits of $\mathcal{M}$. Also, we show that Add$(\mathcal{M})$ is an n-cluster tilting subcategory of $Λ$-Mod if and only if Add$(\mathcal{M})$ is a maximal n-rigid subcategory of $Λ$-Mod if and only if $\lbrace X\in Λ$-Mod$~|~ {\rm Ext}^i_Λ(\mathcal{M},X)=0 ~~~ {\rm for ~all}~ 0

description: Cladodes Solier, 1849 (Figure 3 C – E)
 Cladodes can be distinguished from the other taxa at the Serra dos Órgãos by the following combination of characters: flabellate antenna; laterotergite strongly sclerotised and triangular; absence of lanterns on sterna VI and VII; and paramere without dorso-lateral projections. Clypeus may be medially or completely connate to frons, or connected to it by membrane. Interestingly, this genus has interspecific variation in the agonistic smell (i.e. delivered when disturbed): while some have a wooden, perfume-like smell (e.g. C. stellata Gorham 1880, Fig. 11), others have a ‘ wet dog ’ -like smell (C. illigeri (Kirby 1818), Fig. 10). Note that this is entirely different from the well-known grass-like smell of most taxa such, as Ethra (see above), or the almond-like smell of Memoan (Silveira and Mermudes, 2013). Though the chemical basis for such differences is yet unknown, these differences can help sorting species in the field, which could be especially useful to discriminate among mimetic species. Females and immature stages unknown. Cladodes is currently under review, and its definition will substantially change soon (Bocakova et al. in prep.).
