description: Within the theory of finance, capital structure is one of the most important and controversial themes. Disagreements concerning the possible existence of an optimal capital structure, and the possibility that other reasons explain how organizations define their capital structure, have persisted over the years. Several studies have already been conducted on this subject. However, despite advances, there is still a long way to go. In this context, this study aimed to analyze the debt and the determinants of mills and distilleries of Brazilian sugarcane industry in the period from 1998 to 2013, considering the study restriction regarding this topic in the industry. In terms of methodology, the present study is descriptive and quantitative in nature. The method chosen for the data analysis was the regression model with panel data. The consolidated annual financial statements of the mills and distilleries were collected from the base of the Gazeta Mercantil, on the websites of both organizations and in the publications in the Diário Oficial da União. Based on a sample of 16 industry organizations on a balanced panel, the results showed that, on average, the plants use 62.5% of third party capital to finance their investments. The factors profitability, growth variation, size, and type of capital proved decisive, while cash generation was not statistically significant. Finally, we conclude that the sugar-energy sector is more aligned with the Pecking Order theory

description: The problem of calculating the ac losses in a superconductor strip with a transport current placed inside superconducting environments is studied analytically in the frame of the critical state model. Exact results obtained by the method of images for the commonly employed flat ground plates are used to derive power losses and, consequently, the nonlinear resistance depending on the ac frequency, current amplitude and the distance to the ground plates. The resistance is strongly reduced when the distance between the strip and the shields becomes small.

description: Chemistry researchers are frequently evaluated on the perceived significance of their work with the citation count as the most commonly-used metric for gauging this property. Recent studies have called for a broader evaluation of significance that includes more nuanced bibliometrics as well as altmetrics to more completely evaluate scientific research. To better understand the relationship between metrics and peer judgements of significance in chemistry, we have conducted a survey of chemists to investigate their perceptions of previously published research. Focusing on a specific issue of the Journal of the American Chemical Society published in 2003, respondents were asked to select which articles they thought best matched importance and significance given several contexts: highest number of citations, most significant (subjectively defined), most likely to share among chemists, and most likely to share with a broader audience. The answers to the survey can be summed up in several observations. The ability of respondents to predict the citation counts of established research is markedly lower than the ability of those counts to be predicted by the h-index of the corresponding author of each article. This observation is conserved even when only considering responses from chemists whose expertise falls within the subdiscipline that best describes the work performed in an article. Respondents view both cited papers and significant papers differently than papers that should be shared with chemists. We conclude from our results that peer judgements of importance and significance differ from metrics-based measurements, and that chemists should work with bibliometricians to develop metrics that better capture the nuance of opinions on the importance of a given piece of research.

description: Fluorescent inorganic quantum dots are highly promising for biomedical applications as sensing and imaging agents. However, the low internalization of the quantum dots, as well as for most of the nanoparticles, by living cells is a critical issue which should be solved for success in translational research. In order to increase the internalization rate of inorganic CdSe/ZnS quantum dots, they were functionalized with a fluorinated organic ligand. The fluorinated quantum dots displayed an enhanced surface activity, leading to a significant cell uptake as demonstrated by in vitro experiments with HeLa cells. Experimental and computational results of Langmuir monolayers of the DPPC phospholipid as a model cell membrane with in vitro experiments for analyzing the mechanism of internalization of the fluorinated CdSe/ZnS quantum dots, were combined. Surface pressure-molecular area isotherms suggested that the physical state of the DPPC molecules was greatly affected by the quantum dots. UV–vis reflection spectroscopy and Brewster Angle Microscopy as in situ experimental techniques further confirmed the significant surface concentration of quantum dots. The disruption of the ordering of the DPPC molecules was assessed. Computer simulations offered detailed insights in the interaction between the quantum dots and the phospholipid, pointing to a significant modification of the physical state of the hydrophobic region of the phospholipid molecules. This phenomenon appeared as the most relevant step in the internalization mechanism of the fluorinated quantum dots by cells. Thus, this contribution sheds light on the role of fluorine on the surface of inorganic nanoparticles for enhancing their cellular uptake.
title: Streptococcus pneumoniae colonisation in a cohort of SE Asian infants
Creators: name: Turner, Paul
Publisher: name: The Open University
Year: 2012

description: Background:Streptococcus pneumoniae is a leading cause of childhood mortality and morbidity. Nasopharyngeal colonisation precedes infection but the dynamics, modifiers, and immunological outcomes of colonisation in infancy are incompletely understood.

Methods: We conducted a longitudinal pneumococcal colonisation study of mothers and infants in Maela refugee camp in NW Thailand. 965 infants were followed from birth until 24 months.

Results: Pneumococcal colonisation occurred early in infancy (median 46d). Vaccine serotypes (PCVI3) accounted for 55.8% of isolates from infants and 27.5% from mothers. II Non-typeable pneumococcal colonisation was commOD. Previous colonisation did not result in protection against subsequent pneumococcal acquisitions in infancy, although serotype reacquisitions tended. to be delayed and of shorter duration.

Positive associations were found between colonisation by pneumococci and Haemophilus influenzae (OR 2.9, PMoraxella catarrhalis (OR 2.1, PStaphylococcus aureus colonisation was negatively 3associated (OR 0.3, PP=.02).

Serum IgG anti-capsular antibody responses to colonisation varied by capsule and increased with age: these antibodies were not protective against colonisation in infancy_ Although cord bloods had high titres of IgG to pneumococcal surface and virulence , proteins, none were associated with delayed infant colonisation. These proteins were immunogenic in infants but antibodies did not protect against colonisation. Latex sweep serotyping was 3.9 times, and microarray 4.4 times, more likely to detect multiple pneumococcal serotype co-colomsations than standard WHO protocol culture (P
Conclusions: Pneumococcal colonisation is influenced by previous exposure to homologous and heterologous serotypes. Neither previous exposure nor serum antibodies to capsule or surface proteins protect against colonisation in the first 24 months of life. WHO methodology significantly underestimates multiple serotype colonisations. These colonisation data will be a valuable baseline to compare with future studies following regional introduction of pneumococcal conjugate vaccines.

description: This paper aims to estimate the eco-efficiency of agriculture in the state of Goias, Brazil, using the Data Envelopment Analysis (DEA) method, combined with Directional Distance Function (DDF). Therefore, data obtained from the Agricultural Census of 2006 of all 246 municipalities in the state of Goias was used, with eight variables: four inputs, three desirable outputs, and one undesirable output. The results allowed us to map and classify the municipalities into four categories: i) eco-efficient; ii) low ecoinefficiency; iii) average eco-inefficiency; and iv) high eco-inefficiency. The results showed that sixty-eight municipalities were considered eco-efficient, with Alto Paraíso de Goias and Aparecida do Rio Doce appearing as benchmarks for half of the sample cities. The municipality with the worst performance was Quirinopolis. The overall score of eco-inefficiency in the State was of 0.77, which indicates that resource savings with labor, capital and other inputs could reach R$ 1,290,264,669.94 and 194,047 ha of land. Concurrently, it is possibleto increase revenue by R$ 2,835,872,090.34, and 1,534,833 ha of protected area, while reducing degraded areas by 20,470 ha. Thus, these results support the hypothesis that the apparent antagonism between economic and environmental objectives does not prevent the formulation of policies consistent with the improvement of environmental economic sustainability.

description: This study aims at contributing to identifying technological innovation opportunities, as well as the characteristics of the assimilation processes of soybean production. The concept of absorptive capacity (AC) provides the theoretical lens for analyzing the empirical evidence that was collected. AC implies that the organization recognizes the value of knowledge as a resource, absorbing, assimilating and modifying it in order to transform it into economic returns. In this study, we analyzed the assimilating process of new technologies of three large rural companies in Campo Novo do Parecis, municipality located in the largest soybean producing state of Brazil - Mato Grosso. Micro-level aspects were considered, i.e., the closest and direct contacts of the property in the countryside, in search for new technologies. The conducted interviews were based on five analysis categories regarding the subject, comprising history and background, need to learn, market and environment effects, and internal factors that influence the absorptive capacity and its results. We identified several sources to which the companies seek knowledge for their productive activities, as well as the process that involves acquisition, assimilation and results. The study contributes on portraying the reality involving the AC in a context understudied in the molds of what was proposed here.

description: We study theoretically the parametric down conversion and squeezing of microwaves using cavity quantum electrodynamics of a superconducting Cooper pair box (CPB) qubit located inside a transmission line resonator. The non-linear susceptibility χ_2 describing three-wave mixing can be tuned by dc gate voltage applied to the CPB and vanishes by symmetry at the charge degeneracy point. We show that the coherent coupling of different cavity modes through the qubit can generate a squeezed state. Based on parameters realized in recent successful circuit QED experiments, squeezing of 95% ~ 13dB below the vacuum noise level should be readily achievable.

description: This study aims to analyze the process of innovation in the poultry production chain of a cooperative of western Santa Catarina, Brazil. The object of study was an agribusiness that coordinates the development of the main activities. This is a case study with a qualitative approach. Interviews were conducted with six managers of the agro-industry, ranging from the production of dies to the distribution of the finished products, through incubation activities, production of feed and poultry, as well as slaughter and processing. We verified that the object of this study mainly develops incremental innovations that are largely based on suppliers of both inputs as machinery and equipment, in regard to process innovations. In the case of product innovations, there is the use of internal sources of knowledge, especially by the sectors of R&D and product and process engineering, considering rare the cooperation or partnerships with external agents, such as research centers, universities and competitors.

description: This study adopts representation as a concept in Critical Discourse Analysis (CDA) to explicate the way Nigerian musicians render their songs with regards to cyber-crime. It has been observed that Hip Pop artistes in the Nigerian music industry play collaborative roles by either supporting cyber-crimes openly or making them part of their poetic rendition. This situation has brought the artistes and the security agencies at loggerheads. Popular culture as represented in the music industry seems to largely support internet fraud in their lyrics; a situation that has painted the larger Nigerian society in bad light. Both within and outside the country, Nigerian celebrities’ lifestyles leave much to be desired; with the display of questionable affluence on the internet. It is therefore based on this and other sundry issues as revealed within the circles of the cyber criminals, the Hip Pop Artistes and the Nigerian security agencies that prompted the need for this academic investigation. Data for the study were elicited from the songs of three Nigerian Hip Pop Artistes: NkemOwoh “I Go Chop Your Dollar”, Olu & Tolu Maintain “Yahoozee” and Naira Marley “Am I a Yahoo Boy?” The study reveals cases of inordinate ambition, quest for materialism, glamorization/de-glamorization and sex/sexuality Key Words: Popular Culture, Cybercrimes, Discourse, Nigerian Musicians, Internet Fraud

description: The near infrared (IR) absorption spectra of starburst galaxies show several atomic and molecular lines from red supergiants which can be used to infer reliable stellar abundances. The metals locked in stars give a picture of the galaxy metallicity prior to the last burst of star formation. The enrichment of the new generation of stars born in the last burst can be traced by measuring the hot gas in the X-rays. For the first time detailed stellar abundances in the nuclear region of the starburst galaxy M82 have been obtained. They are compared with those of the hot gas as derived from an accurate re-analysis of the XMM and Chandra nuclear X-ray spectra. The cool stars and the hot gas suggest [Fe/H]=-0.35+/-0.2 dex, and an overall [Si,Mg/Fe] enhancement by 0.4 and 0.5 dex, respectively. This is consistent with a major chemical enrichment by SNe II explosions in recursive bursts on short timescales. Oxygen is more puzzling to interpret since it is enhanced by 0.3 dex in stars and depleted by 0.2 dex in the hot gas. None of the standard enrichment scenarios can fully explain such a behavior when compared with the other alpha-elements.

description: The case studied, Ipanema coffee, illustrates how market demand for high quality product conducted the company to build longterm relationship with its suppliers, the farmers, in order to guarantee access to high value consumer international markets. Data was collected through in-depth interviews with the major company shareholder and also with the marketing director along with desk research for the coffee sector panorama. The long term contract appeared as a prosperous alliance strategy in the measure that a) reduces the risk related to the coffee quality attributes, b) creates a competitive advantage though the appropriability of specific assets related to the coffee growing and processing, c) permits the creation of a brand name capital. The relational exchange has been successful once it allowed the firm to export 1 million bags for 25 countries. On the other hand, as expected in partnerships, the other party, the farmers, has incentives to continue the relationship, once it permits: a) international market access, b) premium prices, c) risk minimization with hedge operation, and d) no investment in coffee processing structure.

description: We investigate a model of two Kondo impurities coupled via an Ising interaction. Exploiting the mapping to a generalized single-impurity Anderson model, we establish that the model has a singlet and a (pseudospin) doublet phase separated by a Kosterlitz-Thouless quantum phase transition. Based on a strong-coupling analysis and renormalization group arguments, we show that at this transition the conductance G through the system either displays a zero-bias anomaly, G ~ |V|^{-2(\sqrt{2}-1)}, or takes a universal value, G = e^2/(π\hbar) cos^2[π/(2\sqrt{2})], depending on the experimental setup. Close to the Toulouse point of the individual Kondo impurities, the strong-coupling analysis allows to obtain the location of the phase boundary analytically. For general model parameters, we determine the phase diagram and investigate the thermodynamics using numerical renormalization group calculations. In the singlet phase close to the quantum phase transtion, the entropy is quenched in two steps: first the two Ising-coupled spins form a magnetic mini-domain which is, in a second step, screened by a Kondoesque collective resonance in an effective solitonic Fermi sea. In addition, we present a flow equation analysis which provides a different mapping of the two-impurity model to a generalized single-impurity Anderson model in terms of fully renormalized couplings, which is applicable for the whole range of model parameters.

description: Federal tax policy affects the economic behavior and well-being of farm households, as well as the management and profitability of farms. Recent calls for reforming current tax law could fundamentally changing the Federal income tax system by eliminating most itemized deductions and modifying credits, while restructuring capital gains and dividend tax rates, lowering tax rates on individual and business income, as well as reducing the number of tax brackets. At the same time, the Tax Cuts and Jobs Act calls for the expansion of some business provisions, and in particular that relate to capital cost recovery. The reforms, if enacted, could have a significant impact on the after-tax income and well-being of both farms and farm households. This paper uses farm-level data from USDA’s Agricultural Resource Management Survey to examine the current tax situation for farm households and to evaluate the impact the Tax Cuts and Jobs Act may have on them.

description: Estimates of tax reform’s impacts usually provide an economy-wide assessment, but attention at the industry or sectoral level is often limited. Our study uses a computable general equilibrium (CGE) model to estimate the disaggregated impacts of tax reform. Focusing on agriculture, we use survey data to calculate the tax rates faced by primary agriculture producers; and IRS data to capture tax rates for all other producers. Conducting a tax reform scenario that lowers taxes for individuals and corporations, we find that impacts on investment weigh heavily on model results. That is, firms that are attractive to domestic and foreign investment have gains in demand for their products; while other sectors, such as primary agriculture, experience decreases in production. These results highlight the demand saturation for products, especially for food, in the United States. As such, we provide an extension of the tax reform scenario, equalizing tariffs faced by U.S. agricultural producers with global tariffs. Those results indicate that foreign market access, coupled with tax reform, provides benefits to the entire economy, especially agriculture.

description: We give some new performance results for the Hybrid Monte Carlo (HMC) simulation of dynamical clover-improved Wilson fermions using an improved pseudo-fermion action. The generalisation of even-odd preconditioning for the standard Wilson fermion matrix to the clover-improved case is not unique. In the literature the so called symmetric and asymmetric versions are discussed. Most of the previous simulations of dynamical clover-improved Wilson fermions were done with the asymmetric version. Only recently, the JLQCD collaboration has pointed out that the symmetric version leads to a better performance of the HMC algorithm. Here, we show that also in combination with an improved pseudo-fermion action, the symmetric version of even-odd preconditioning leads to a better performance. For our lightest quark mass, which corresponds to $m_{PS}/m_{V} \approx 0.44$, we see a gain in performance by a factor of about 1.3.

description: Time-resolved soft-X-ray photoemission spectroscopy is used to simultaneously measure the ultrafast dynamics of core-level spectral functions and excited states upon excitation of excitons in WSe$_2$. We present a many-body approximation for the Green's function, which excellently describes the transient core-hole spectral function. The relative dynamics of excited-state signal and core levels reveals a delayed core-hole renormalization due to screening by excited quasi-free carriers, revealing an excitonic Mott transition. These findings establish time-resolved core-level photoelectron spectroscopy as a sensitive probe of subtle electronic many-body interactions and an ultrafast electronic phase transition.

description: We estimate a fixed effects county level panel data model to relate socioeconomic variables to opioid-related drug overdoses, which cost the nation in excess of $430bn in 2015. In addition to demographic and labor market variables we include lagged employment shares by major industry and self-employment shares, as well as cumulative counts of presidentially declared disasters. We find that rurality, as measured by lower population density, is associated with higher overdose rates. Also, for each $10,000 reduction in net income per farm, opioids overdoses rose by 10% from a national average of 10.2 deaths per 100,000 people.

title: Induction of 'Hox' genes and genome wide identification of Hox binding sites in mice
Creators: name: De Kumar, Bony
Publisher: name: The Open University
Year: 2013

description: Hox genes encode a family of transcription factors that play highly conserved regulatory roles in specifying the properties of tissues in developing embryos. Very little is known about how HOX proteins control the cellular and developmental processes governing morphogenesis through regulation of down-stream target genes. The goal of this research was to investigate on a genome-wide basis, the rules and principles which underlie the binding of different HOX proteins to target sites and understand the basis for their distinct specificities. I utilized the programmed differentiation of mouse embryonic stem cells into a neural fate with retinoids and genomic technologies to systematically investigate binding properties of two HOX proteins, HOXA1 and HOXBI and their cofactors PBX and MEIS. I analyzed the induction properties of the cells and the transcriptional dynamics and epigenetic states in Hox clusters to explore the differentiation process. An extensive and dynamic pattern of transcriptional activity indicates that Hox clusters generate a large number of non-coding RNAs which may impact their activation and chromatin states. Global identification of HOXB1, HOXA1, PBX and MEIS binding regions by chromatin immune precipitation and high throughout sequencing (ChIP-seq) has generated insight into many potential Hox target genes. HOXA1 binding peaks generally overlapped with those of PBX and MEIS, supporting their roles as HOX co-factors. The sites bound by HOXBl uncovered new classes of binding motifs. Regulatory assays demonstrated that many of these novel motifs functioned as neuronal enhancers. Many HOXB1 binding peaks have closely associated REST motifs and bind the REST repressor complex, which is important in neuronal differentiation. The close association of REST and HOXB1 binding sites provides a mechanism for coordinating cell differentiation programs in neurogenesis. This research has uncovered novel properties of HO X proteins and their co-factors that underlie their role as master regulators of patterning and morphogenesis.

description: Organic-inorganic hybrid halide perovskites have ignited tremendous interests for photovoltaic applications. However, their nonlinear optical response has not been studied although many of these structures lack the centrosymmetry and exhibit ferroelectricity. In this work, we employ our developed large-scale parallel, first-principles simulation tool (ArchNLO) to explore second-order nonlinear optical properties of a typical family of organic-inorganic hybrid halide perovskites, CH3NH3MX3 (M= Ge, Sn, Pb; X=Cl, Br, I). We find that these hybrid perovskites exhibit second harmonic generation and linear electro-optic effect. The nonlinear optical effects are strongly influenced by the types and positions of cations/anions and corresponding band gaps. Particularly, the distorted cubic phase, which is essentially triclinic, of CH3NH3SnI3 shows significant second harmonic generation and electro-optic effect, which are comparable with those widely used materials, such as GaAs. These second-order optical properties of organic-inorganic hybrid halide perovskites and their low-temperature, solution-based fabrication pave the way for achieving and implementing nonlinear optical devices with low cost.

description: The isoscalar octupole response of a heavy spherical nucleus is analyzed in a semiclassical model based on the linearized Vlasov equation. The octupole strength function is evaluated with different degrees of approximation. The zero-order fixed-surface response displays a remarkable concentration of strength in the $1\hbarω$ and $3\hbarω$ regions, in excellent agreement with the quantum single-particle response. The collective fixed-surface response reproduces both the high- and low-energy octupole rsonances, but not the low-lying $3^{-}$ collective states, while the moving-surface response function gives a good qualitative description of all the main features of the octupole response in heavy nuclei. The role of triangular nucleon orbits, that have been related to a possible instability of the spherical shape with respect to octupole-type deformations, is discussed within this model. It is found that, rather than creating instability, the triangular trajectories are the only classical orbits contributing to the damping of low-energy octupole excitations.

description: Food safety hazards arising at the farm level affect the health of agricultural households as well as access to high value markets, which typically require that produce meets strict quality and food safety standards. Smallholder farmers face a number of barriers to improving the quality and safety of their produce, including a lack of awareness about safety and quality standards, the cost of equipment required to improve these, and the failure of premium prices to pass through to farmers. In this paper, we examine how lifting each of these barriers affects Ghanaian groundnut farmers’ adoption of post-harvest practices that reduce aflatoxin contamination. Aflatoxins are carcinogenic secondary metabolites of certain molds, which cause serious health problems including liver cancer. Common in groundnuts and maize, staple foods in much of Africa, aflatoxins pose a major threat to food safety and hinder the development of local agricultural value chains and export markets. Aflatoxin contamination can be substantially reduced through low-tech, low-cost post-harvest practices. We conducted a randomized control trial in northern Ghana with 1,005 farmers over the course of two seasons to test the imapct of three interventions to improve post harvest practices and reduce aflatoxin levels: (1) farmer training on aflatoxin and its prevention, (2) distribution of free drying tarps, and (3) a price premium for groundnuts found to comply with the local aflatoxin regulation. Training farmers substantially improves post-harvest practices. Tarp receipt further improves some practices, particularly with regards to drying surface. Surprisingly, we find that the price premium had little effect on reported or observed practices, and few farmers even sold nuts at this premium despite achieving compliance. Relative to training alone, tarp distribution reduced afaltoxin contamination by approximately 50 percent in the region and year when background levels were highest. The market premium also reduced aflatoxin levels, although to a lesser extent.
Chandra Observations and Monte Carlo Simulations of the Grain-Scattered Halo of the Binary X-Ray Pulsar 4U 1538-52

description: Properties of the X-ray halo of the eclipsing X-ray pulsar 4U 1538-52 are derived from a 25 ksec observation by the Chandra X-Ray Observatory. Profiles of the halo, compiled in two energy ranges, 2 to 4 keV and 4 to 6 keV, and three time intervals before and after an eclipse immersion, exhibit a three-peak shape. The observed profiles are fitted by the profiles of a simulated halo generated by a Monte Carlo ray-tracing code operating on a model of three discrete clouds and a spectrum of the photons emitted by the source over a period of time extending from 270 ksec before the observation began till it ended. The distances of the two nearer dust clouds are fixed at the distances of the peaks of atomic hydrogen derived from the 21-cm spectrum in the direction of the X-ray source, namely at 1.30 and 2.56 kpc. A good fit is achieved with the source at a distance 4.5 kpc, the distance of the third cloud at 4.05 kpc, the total scattering optical depth of the three clouds equal to 0.159 at 3 keV, and the column density of hydrogen set to 4.6x10^22 cm^-2. With Av=6.5 mag for the binary companion star, QV Nor, the ratio of the scattering optical depth at 3 keV to the visual extinction is 0.0234 mag^-1.

description: With phase space analysis approach, we investigate thoroughly the self-trapping phenomenon for two weakly coupled Bose-Einstein condensates (BEC) in a symmetric double-well potential. We identify two kinds of self-trapping by their different relative phase behavior. With applying a periodic modulation on the energy bias of the system we find the occurrence of the self-trapping can be controlled, saying, the transition parameters can be adjusted effectively by the periodic modulation. Analytic expressions for the dependence of the transition parameters on the modulation parameters are derived for high and low frequency modulations. For an intermediate frequency modulation, we find the resonance between the periodic modulation and nonlinear Rabi oscillation dramatically affects the tunnelling dynamics and demonstrate many novel phenomena. Finally, we study the effects of many-body quantum fluctuation on self-trapping and discuss the possible experimental realization of the model.

description: The revolution of information technology and communications has drastically changed the way people conduct business. With the rapid emergence of Taobao villages and other e-trading platforms in its rural areas, China is leading the developing world in rural e-commerce. Despite the potential of e-commerce to improve agriculture profits and farmer’s income, whether and to what extent farmers really benefit from it remains a question. Using household survey data from farmers selling products through e-trading platform and those selling products through traditional market channel, we aim to rigorously assess the effects of e-commerce adoption on farmer’s income and identify the key mechanisms through which the impact comes about. Propensity score matching (PSM) methods were adopted to deal with the fact that farmers’ participation in selling products through e-commerce is not random. The PSM results show that the adoption of e-commerce has a positive effect on farmers’ income, especially in the villages with more e-commerce adoption. And the increase in the profit margin and the growth of sales are the two main channels through which e-commerce impacts farmers’ income.
