description: The decline of Southern Europe’s traditional sheep- and goat-farming systems creates a need for studies on the economic determinants that underlie their production processes. Using data from the FADN, we built a panel of 37 regions from 5 countries over an 8-year period (2004–2012). A Cobb-Douglas was specified and a stochastic frontier production was estimated. Total Factor Productivity (TFP) and its components were calculated. The farms have had sustained, positive development of TFP since 2008, with a significant correlation with the labour factor of production. We detected moderate technical progress change, which was accompanied by decreasing efficiency.

description: The purpose of this article is to design and empirically evaluate the Whole Farm Insurance (WFI) over the conventional insurance programs in Zanjan province of Iran. Historical farm-level and county-level data were used to estimate yield and price density functions. Both parametric and non-parametric methods were applied for predicting the future values and the PQH simulation method was utilized to calculate premium rates. Results revealed that loss ratios of the WFI are lower for farmers who insured more than one crop. Additionally, utilizing WFI reduces premiums. Moreover, premiums obtained from nonparametric method are relatively lower compared to the parametric approachy.

description: Analytic arguments have been advanced that the degree of differential rotation in a neutron star depends on whether the topology of the internal magnetic field is open or closed. To test this assertion, the ideal-magnetohydrodynamics solver PLUTO is employed to investigate numerically the flow of an incompressible, viscous fluid threaded by a magnetic field with open and closed topologies in a conducting, differentially rotating, spherical shell. Rigid body corotation with the outer sphere is enforced on the Alfvén time-scale, along magnetic field lines that connect the northern and southern hemispheres of the outer sphere. Along other field lines, however, the behavior is more complicated. For example, an initial point dipole field evolves to produce an approximately closed equatorial flux tube containing at least one predominantly toroidal and approximately closed field line surrounded by a bundle of predominantly toroidal but open field lines. Inside the equatorial flux tube, the field-line-averaged magnetic tension approaches zero, and the fluid rotates differentially, adjusting its angular velocity on the viscous time-scale to match the boundary conditions on the flux tube's toroidal surface. Outside the equatorial flux tube the differential rotation increases, as the magnetic tension averaged along open field lines decreases.

description: Let u be a cyclic word in a free group F_n of finite rank n that has the minimum length over all cyclic words in its automorphic orbit, and let N(u) be the cardinality of the set {v: |v|=|u| and v=ϕ(u) for some ϕ\in AutF_n}. In this paper, we prove that N(u) is bounded by a polynomial function of degree 2n-3 with respect to |u| under the hypothesis that if two letters x, y occur in u, then the total number of x and x^{-1} occurring in u is not equal to the total number of y and y^{-1} occurring in u. We also prove that 2n-3 is the sharp bound on the degree of polynomials bounding N(u). As a special case, we deal with N(u) in F_2 under the same hypothesis.

Subjects: liturgical music; congregational worship; churches.

description: Abstract: This study examines the role of liturgical music in enhancing worship experiences, focusing on emotional and spiritual engagement, participatory elements, and contextual factors. Liturgical music, a vital aspect of Christian worship, plays a profound role in fostering emotional connection, spiritual reflection, and community engagement. Despite its foundational presence, the mechanisms through which music impacts the worship experience remain an area of interest for scholars and practitioners alike. A mixed-methods approach was employed, incorporating surveys from 500 congregants across 10 Christian denominations, semi-structured interviews with 30 church leaders and music directors, and participant observation during 20 worship services. The research aimed to identify key elements of liturgical music, including lyrics, melody, and rhythm, that contribute to emotional and spiritual engagement. Quantitative data were analyzed using descriptive statistics, while qualitative data underwent thematic analysis. The study revealed that 87% of respondents felt an enhanced emotional connection during worship through music. Lyrics were identified as the most impactful element (mean score 4.6/5), followed by melody and rhythm. Contemporary music styles fostered higher physical engagement, while traditional hymns strengthened feelings of historical connection. The results highlight the multifaceted role of music in worship, emphasizing the importance of well-crafted lyrics, the participatory nature of congregational singing, and the influence of contextual factors, such as musician skill and sound quality. The alignment of music with service themes also positively impacted worship satisfaction. Liturgical music significantly enhances worship by deepening emotional engagement, fostering communal participation, and uniting congregants across generations. The findings provide practical insights for church leaders and music directors in crafting meaningful worship experiences.

description: In this paper we present a case study of the impoverished ornamental fishing situation in the Inirida Fluvial Confluence (IFC) in Colombia. For this purpose fieldwork was conducted to obtain primary data from fishermen in the zone. The results indicate that effort applied to create different economic activities have no significant impact on the income of fishermen. Community Agreements for Responsible Fishing (CARF) could be an effective policy for management of the resource; nevertheless, their establishment can bring a loss of livelihoods when there are no clear alternative income sources, and may be incompatible with poverty alleviation objectives. Due to this, alternative sources of income should also be promoted in policy-making.

description: The Bio-diesel Initiative wishes to develop a small-scale facility in UBC, turning WVO into bio-diesel to partially fuel UBC Plant Operation vehicles. The purpose of the MECH 457 project is to develop a WVO Pick-up System that will perform the primary function of collecting WVO from various locations on campus to the processing plant. During the conceptualization phase, the team identified various concepts to implement the key function of collecting WVO. After preliminary analysis, these concepts were narrowed down to those that are more feasible. After evaluation, the best three concepts are the small buckets, manual crane (to move large containers) and the small buckets with crane (crane facilitates drop-off of multiple small buckets) concepts. These concepts were presented to the client and he prefers the small buckets with crane concept. The reasons were that this concept has the benefits of the small buckets concept (clean, inexpensive, etc.) while reducing physical and time requirements during drop-off. More importantly, since the drop-off location is uncertain, using this concept makes the drop-off process adaptable to any drop-off requirements (moving WVO to the 5th floor of CHBE Building) Disclaimer: “UBC SEEDS provides students with the opportunity to share the findings of their studies, as well as their opinions, conclusions and recommendations with the UBC community.

description: The large deviation properties of equilibrium (reversible) lattice gases are mathematically reasonably well understood. Much less is known in non--equilibrium, namely for non reversible systems. In this paper we consider a simple example of a non--equilibrium situation, the symmetric simple exclusion process in which we let the system exchange particles with the boundaries at two different rates. We prove a dynamical large deviation principle for the empirical density which describes the probability of fluctuations from the solutions of the hydrodynamic equation. The so called quasi potential, which measures the cost of a fluctuation from the stationary state, is then defined by a variational problem for the dynamical large deviation rate function. By characterizing the optimal path, we prove that the quasi potential can also be obtained from a static variational problem introduced by Derrida, Lebowitz, and Speer.

description: In this article we introduce a natural extension of the well-studied equation for harmonic maps between Riemannian manifolds by assuming that the target manifold is equipped with a connection that is metric but has non-vanishing torsion. Such connections have already been classified in the work of Cartan. The maps under consideration do not arise as critical points of an energy functional leading to interesting mathematical challenges. We will perform a first mathematical analysis of these maps which we will call harmonic maps with torsion.

This paper analyses the competitive advantages between independent firms and firms belonging to a business group, focusing on the Spanish wine industry. The authors studied 339 wineries, compared their resources and capabilities, the strategies used and their business performance. The results suggest that while resources and capabilities are key for independent firms it is the business strategy that is most important for firms belonging to a business group. The study sheds more light on the application of specific elements to explain a firm’s business performance.

Surveys were carried out directly to peach farmers in seven counties of Tungurahua such as Ambato, Cevallos, Mocha, Patate, Pelileo, Píllaro and Tisaleo. The results indicated that the most relevant factors were: farmer age, sown area, fruit selection, reason for fruit growing, type of production and production issues.

description: In the last ten years, a number of ``Conventional Fluctuation Theorems'' have been derived for systems with deterministic or stochastic dynamics, in a transient or in a non-equilibrium stationary state. These theorems gave explicit expressions for the ratio of the probability to find the system with a certain value of entropy (or heat) production to that of finding the opposite value. A similar theorem for the fluctuations of the work done on a system has recently been demonstrated experimentally for a simple system in a transient state, consisting of a Brownian particle in water, confined by a moving harmonic potential. In this paper we show that because of the interaction between the stochastic motion of the particle in water and its deterministic motion in the potential, very different new heat theorems are found than in the conventional case. One of the consequences of these new heat Fluctuation Theorems is that the ratio of the probability for the Brownian particle to absorb heat from rather than supply heat to the water is much larger than in the Conventional Fluctuation Theorem. This could be of relevance for micro/nano-technology.

These include the reflection and transmission amplitudes for Laughlin quasiparticles at a point contact between two g=1/2 Luttinger liquids, and the e->e_{edge} at a point contact between a Fermi liquid and a g=1/3 Luttinger liquid (all liquids chiral or not). These results are obtained in closed form, and give rise to rather simple expressions for the probabilities of the most basic processes of non Fermi liquid physics at these special values of the couplings.

description: In order to understand the role of the different processes that drive galaxy evolution in clusters, we need comprehensive studies that simultaneously examine several of the most important characteristics of galaxies. In this work we examine the physical properties of cluster galaxies at z=0.45 attending to the degree of distortion of their rotation curves. Regular rotating galaxies were included in our Tully-Fisher analysis while the distorted ones were used to study the role of cluster-specific interactions with respect to star formation and AGN activity. We report a higher fraction of galaxies with irregular gas kinematics in the cluster environment than in the field. Cluster galaxies with regular rotation display a moderate brightening in the B-band Tully-Fisher relation compatible with the gradual evolution of the stellar populations with lookback time, and no significant evolution in the stellar-mass Tully-Fisher relation, in line with previous studies at similar redshift. Average specific star formation rate (sSFR) values are slightly lower in our cluster sample (-0.15 dex) with respect to the main sequence of star-forming galaxies, confirming the role of the environment in the early quenching of star formation in clusters. Finally, we carried out an exploratory observational study on the stellar-to-halo mass relation finding that cluster galaxies tend to have slightly lower stellar mass values for a fixed halo mass compared to their field counterparts.

description: Different ways of calculating mortality ratios during epidemics have yielded very different results, particularly during the current COVID-19 pandemic. We formulate both a survival probability model and an associated infection duration-dependent SIR model to define individual- and population-based estimates of dynamic mortality ratios. The key parameters that affect the dynamics of the different mortality estimates are the incubation period and the time individuals were infected before confirmation of infection. We stress that none of these ratios are accurately represented by the often misinterpreted case fatality ratio (CFR), the number of deaths to date divided by the total number of confirmed infected cases to date. Using data on the recent SARS-CoV-2 outbreaks, we estimate and compare the different dynamic mortality ratios and highlight their differences. Informed by our modeling, we propose more systematic methods to determine mortality ratios during epidemic outbreaks and discuss sensitivity to confounding effects and uncertainties in the data.

description: Agriculture in the Arkansas Delta region is dependent upon the accessibility of irrigation water. The most common irrigation water source is groundwater. This practice has led to the depletion of groundwater which is having a damaging influence on the natural resources of the state and the productions costs of agriculture in the region. The adoption of reservoirs and tail-water recovery systems are being promoted as a way of minimizing groundwater depletion and promoting surface water irrigation. Despite the long term benefits of surface water use, many producers are reluctant to adopt the water saving practices. To better understand the barriers of adoption, this project uses the responses from producers who took part in the Arkansas Irrigation Survey in 2016. The responses from this survey are used to find which factors are correlated with the adoption of water storage facilities. The research finds that peer networks are positively correlated with the adoption of surface water irrigation. Producers who know someone who has already adopted surface water irrigation practices, are more likely to have adopted. The results of this research can be used to help extension agencies promote surface water irrigation.

description: Federal nutrition assistance programs at farmers' markets are considered effective strategies to support direct marketing of local produce, and to increase consumer access to healthy food in low-income communities. This research consisted of a preliminary exploratory survey for participating FMNP farmers and recipients at the farmers’ markets in the regions of west Tennessee and Puerto Rico. Survey questionnaires were administered to participating FMNP vendors (farmers) and recipients at the farmers’ markets in west Tennessee and Puerto Rico, in cooperation with the respective state agencies (Tennessee Department of Health, Puerto Rico Department of Agriculture and Puerto Rico Department of Family). The results from the study suggest that most recipients and vendors in both locations consider the program to be working effectively. Study findings will also provide policy recommendations to expand and improve the existing program, as well as to enhance direct marketing of local produce.

As an example, we focus on English, French, and Russian languages during the last four months of 2018. The proposed method has three steps. Firstly, it extracts the most trending articles over a chosen period of time. Secondly, it performs a semi-supervised topic extraction and thirdly, it compares topics across languages. The automated processing works with the data that combines Wikipedia's graph of hyperlinks, pageview statistics and summaries of the pages. The results show that people share a common interest and curiosity for entertainment, e.g. movies, music, sports independently of their language. Differences appear in topics related to local events or about cultural particularities.

We find that the branching ratio for detecting electrons vis a vis the traditional neutralino nucleus elastic scattering sensitively depends on the threshold energy. In the case of a light target and a neutralino mass of 100 GeV we estimate it to be around 10 percent assuming a reasonable threshold energy of 250 eV.

description: The high cost associated with the evaluation of Hartree-Fock exchange (HFX) makes hybrid functionals computationally challenging for large systems. In this work, we present an efficient way to accelerate HFX calculations with numerical atomic basis sets. Our approach is based on the recently proposed interpolative separable density fitting (ISDF) decomposition to construct a low rank approximation of HFX matrix, which avoids explicit calculations of the electron repulsion integrals (ERIs) and significantly reduces the computational cost. We implement the ISDF method for hybrid functional (PBE0) calculations in the HONPAS package. We take benzene and polycyclic aromatic hydrocarbons molecules as examples and demonstrate that hybrid functionals with ISDF yields quite promising results at a significantly reduced computational cost. Especially, the ISDF approach reduces the total cost for evaluating HFX matrix by nearly 2 orders of magnitude compared to conventional approaches of direct evaluation of ERIs.

description: Bar code scanning data pertaining to the urban carbohydrate market were analysed. Emphasis was placed on the strategic importance of the data to the marketing of maize meal products. Elasticities indicate that maize meal and potatoes tend to be relatively price inelastic, whilst bread and rice are more price elastic. Important results emanating from the analyses are that the relative price and the convenience of a product play an important role in the purchasing of a product in the carbohydrate market. Characteristics of the consumers of maize meal were determined for both Black and White consumers, thereby enabling a more informed targeting of advertising campaigns. Other strategic information extracted from the data indicates the practical nature and usefulness of such data.

description: The weighted average cost of capital (WACC) represents the cost of all types of capital employed in the business. In few cases, however, is the WACC estimated empirically and the development and illustration of a procedure for its estimation would therefore be valuable for carrying out economic analyses. In this study land values and rental, rates of irrigation land in the Vanderkloof State Water Scheme were used to estimate the cost of equity capital. The capital structure of irrigation farmers was obtained from balance sheet information. The estimated after-tax rates for the WACC varied from 12,3 per cent to 14,0 per cent per year. The cost of equity capital and its contribution to total capital meaningfully influenced the WACC.

description: We consider the Gauss-Bonnet corrected Bardeen black hole solution in 4-D AdS space-time. The solution is obtained by the limiting procedure adopted by Glavan and Lin in 4-D Einstein-Gauss-Bonnet gravity. The general form of first law of black hole thermodynamics is utilized to calculate various thermodynamics variables. The solution exhibit P-v criticality and belong to the universality class of van-der Waals fluid. The effect of Gauss-Bonnet coupling is investigated on critical parameters and inversion temperature.

description: An explicit expression for the numbers $A(n,r;3)$ describing the refined 3-enumeration of alternating sign matrices is given. The derivation is based on the recent results of Stroganov for the corresponding generating function. As a result, $A(n,r;3)$'s are represented as 1-fold sums which can also be written in terms of terminating ${}_4F_3$ series of argument 1/4.

description: The financial position of farmers in the summer grain areas deteriorated drastically over the past decade. The Soil Conversion Scheme was introduced to help farmers to withdraw low potential crop land by establishing perennial pastures. The purpose of this article is to evaluate the conversion of low potential crop land from cash crop production to perennial pastures in terms of a number of objectives. Dynamic linear programming was used as analyzing technique. Typical characteristics for Western Transvaal namely budgets and other coefficients, were used as inputs to assemble a model over an eight year planning horizon. The optimal enterprise combination was determined by taking into account constraints such as quarterly cash flow, fodder flow, and tractor and labour requirements in the maximization of net operating surplus. The "Target MOTAD" approach was used so that the effect of risk could be considered. The results show that given the assumptions and constraints of the model and when risk is taken into account, the net operating surplus is more stable with the conversion to pastures than that with maize production. Risk thus declines, but then the farmers' ability to meet his fixed obligations deteriorates to such an extent that he cannot survive. The above shows that the Soil Conversion Scheme decreases risk but, given the assumptions and constraints of the model, it is not necessarily at present a general economically viable alternative for maize production on low potential soils.
The evidence for a spatially flat Universe

description: We revisit the observational constraints on spatial curvature following recent claims that the Planck data favour a closed Universe. We use a new and statistically powerful Planck likelihood to show that the Planck temperature and polarization spectra are consistent with a spatially flat Universe, though because of a geometrical degeneracy cosmic microwave background spectra on their own do not lead to tight constraints on the curvature density parameter Omega_K. When combined with other astrophysical data, particularly geometrical measurements of baryon acoustic oscillations, the Universe is constrained to be spatially flat to extremely high precision, with Omega_ K = 0.0004 +/-0.0018 in agreement with the 2018 results of the Planck team. In the context of inflationary cosmology, the observations offer strong support for models of inflation with a large number of e-foldings and disfavour models of incomplete inflation.

description: The principle of compositionality, which enables natural language to represent complex concepts via a structured combination of simpler ones, allows us to convey an open-ended set of messages using a limited vocabulary. If compositionality is indeed a natural property of language, we may expect it to appear in communication protocols that are created by neural agents in language games. In this paper, we propose an effective neural iterated learning (NIL) algorithm that, when applied to interacting neural agents, facilitates the emergence of a more structured type of language. Indeed, these languages provide learning speed advantages to neural agents during training, which can be incrementally amplified via NIL. We provide a probabilistic model of NIL and an explanation of why the advantage of compositional language exist. Our experiments confirm our analysis, and also demonstrate that the emerged languages largely improve the generalizing power of the neural agent communication.

description: This study introduces a systems approach to malaria control from an institutional perspective. This approach allows us to characterize the system of complex linkages of health, environmental, agricultural, economic, political, and social organizations that share a common goal of improving living conditions of poor communities through reduced malaria. These linkages are expected to facilitate the generation, dissemination, and application of relevant information by the organizations in the so-called malaria control system. Implicitly assumed by the approach is the premise that the relevant information in the control of malaria is generated everywhere in the society and should therefore be made available to all relevant parties to lead to improvements in the living conditions of people through effective antimalaria activities. The study further describes how to apply the approach, provides in light of the approach a critical assessment of an existing malaria control initiative for sub-Saharan Africa, and with an example from Ghana, indicates the advantages of the approach in the context of planning sustainable malaria control strategies.

description: The effects of the exchange rate of the Rand and of the Australian Dollar, as well as the effect of general price levels on South African wool prices were analysed. The results fail to show an effect of general price levels and the exchange rate of the Rand. South African wool prices are materially affected by Australian prices. However, Australian wool prices again, which dominate the market. are affected by exchange rates of the Australian Dollar. Thus, South African wool prices are indirectly affected by the exchange rate of the Australian Dollar
