description: This paper sorts out the most important factors influencing crop market participation of smallholder farmers in the highlands of Eastern Ethiopia. The study used primary data collected from 385 smallholder farmers during the year 2015. Heckman two-stage and Tobit models were employed for the analyses. Heckman model of first-stage results indicated that households’ decision to participate in crop output markets were influenced by factors such as sex of household head, farming experience, livestock holding, cultivated land size, off/non-farm income, fertilizer used, on-farm income, market distance, and crop diversification. Moreover, the second-stage results revealed that farm households’ intensity of crop output market participation was influenced by different factors such as dependency ratio, cultivated land size, education status, chemical fertilizer, and distance to market. The Tobit model result also indicated that the extent of farm household’s participation in annual crop fertilizer market as buyer is influenced by the amount of cultivated land, land allocated to khat crop, off/ non-farm income (log), amount of manure used and distance to the main road. From policy perspective, we recommend that strategies aimed at improving commercial behaviour of smallholder farmers in the study area should be directed in addressing the determining factors of both crop input and output market participation.

description: In the article, results and findings of a survey aimed at identifying language skills needs of Slovak small, medium-sized and large enterprises operating mainly in agriculture and food processing industry are presented. An online questionnaire was constructed to collect data. 14 out of 50 selected companies responded. Our findings revealed the fact that the Slovak enterprises use mainly English and German when communicating with their headquarters, suppliers and customers. The respondents also require their employees to have the following special language skills: communicating on the telephone, conducting business negotiations and writing business letters in a foreign language. As for language management strategies, the enterprises organize language training courses for their employees within their premises or the employees have to attend language courses outside the premises. The results of the survey conducted in Slovakia and the EU surveys were compared. Based on the results, we suggest stronger cooperation between the SMEs and universities in Slovakia in production of graduates better equipped with the language skills required by the business environment.

description: This paper analysed food consumption patterns in Ghanaian urban households by comparing food commodity budget shares and estimating price and expenditure elasticities for eleven food commodity groups across different income groups. The Linear Approximation Almost Ideal Demand System (LA/AIDS) was applied to the data. Demand for most of the food commodity groups was found to be elastic. The study concluded that generally, across income groups, food commodities respond negatively to changes in food prices and that cereals/bread, roots/tubers, vegetables, meat and fish will remain an important component of urban household food expenditure. Generally, household demographic characteristics such as age, gender and household size had significant effects on urban food demand patterns.

description: This study explores the determinants of income diversification using a sample of 200 farm-level data collected from households in the Garu-Tampane district, Ghana. The Simpson Index of Diversification was used to determine the extent of income diversification while Fractional Response Model, particularly Generalized Linear Model (GLM) was employed to identify the determinants of income diversification. Results from the Simpson Index of Diversification showed that the average income diversification index was 0.65 with the minimum and maximum of 0.13 and 0.83, respectively. No farm household was found to depend solely on a single source of income for its survival. The results from the Generalized Linear Model revealed that extension services, attendance to demonstration fields, membership of Farmer-based Organizations (FBOs), farmer accessibility to credit, the number of days spent on on-farm activities per month and the number of years in maize farming significantly influence income diversification. The study, therefore, concludes that farm-level policies geared towards alternative sources of income for the rural farm household should focus on improving extension services, the formation of farmer-based organizations, use of demonstration fields as well as ensuring farmers’ accessibility to credit.

description: In this article an analytical and numerical study of superconducting thin film with ferromagnetic textures of elliptical geometries in close proximity is presented. The screening currents induced in the superconductor due to the magnetic texture are calculated. Close to the superconducting transition temperature $T_c$ the spontaneous creation of superconducting vortices becomes energy favorable depending on the value of the magnetization and the geometrical quantities of the magnetic texture. The creation of vortices by elliptic dots is more energy favorable than those created by circular ones. The superconductor covered by elliptic dots array exhibits anisotropic transport properties.

description: In a biotechnological process to produce mannitol, heterofermentative lactic acid bacteria were utilized with substrates rich in fructose and nitrogen, sourced from discarded apples and cider fermentation lees, respectively. Two strains of lactic acid bacteria were assessed for their ability to grow and produce mannitol using these by-products from the cider industry. The results showed that cider fermentation lees were less effective in promoting cell growth compared to yeast extract, which led to a delay in the conversion of fructose to mannitol.
Realizing split-pulse x-ray photon correlation spectroscopy to measure ultrafast dynamics in complex matter

description: Split-pulse x-ray photon correlation spectroscopy has been proposed as one of the unique capabilities made possible with the x-ray free electron lasers. It enables characterization of atomic scale structural dynamics that dictates the macroscopic properties of various disordered material systems. Central to the experimental concept are x-ray optics that are capable of splitting individual coherent femtosecond x-ray pulse into two distinct pulses, introduce an adjustable time delay between them, and then recombine the two pulses at the sample position such that they generate two coherent scattering patterns in rapid succession. Recent developments in such optics showed that, while true 'amplitude splitting' optics at hard x-ray wavelengths remains a technical challenge, wavefront and wavelength splitting are both feasible, able to deliver two micron sized focused beams to the sample with sufficient relative stability. Here, we however show that the conventional approach to speckle visibility spectroscopy using these beam splitting techniques can be problematic, even leading to a decoupling of speckle visibility and material dynamics. In response, we discuss the details of the experimental approaches and data analysis protocols for addressing issues caused by subtle beam dissimilarities for both wavefront and wavelength splitting setups. We also show that in some scattering geometries, the Q-space mismatch can be resolved by using two beams of slightly different incidence angle and slightly different wavelengths at the same time. Instead of measuring the visibility of weak speckle patterns, the time correlation in sample structure is encoded in the 'side band' of the spatial autocorrelation of the summed speckle patterns, and can be retrieved straightforwardly from the experimental data. We demonstrate this with a numerical simulation.

description: This study examining the impact of foreign direct investment (FDI) and other macroeconomic variables on agricultural growth in Nigeria from 1981 to 2014, using annual time series data from Central Bank of Nigeria (CBN), World Bank and the United States of America (US) Federal Reserve System. Data was analysed using trend analyses, unit root tests, co-integration tests, ordinary least squares (OLS) regression and Granger causality tests, while the hypothesis was tested with F-test. Results revealed very low FDI inflow into agriculture, not commensurate with the share of agriculture to GDP. All significance were taken at the 5% probability level, i.e. p<0.05. There was positive non-significant relationship between agricultural growth and FDI in agriculture, meaning that FDI in agriculture has no direct impact on agricultural growth or the impact on agricultural growth is masked by other macroeconomic variables. Significant positive relationship exists between agricultural growth and macroeconomic instability, while interest rate differential had a significant negative relationship. There was unidirectional causality running from FDI in agriculture, stock of gross external debts, and variability of consumers’ price index to agricultural growth, while agricultural growth was significant in granger causing macroeconomic instability. Recommendations are government should not involve itself in business, but seek for and encourage more FDI for the agricultural sector, encourage joint ventures between foreign and domestic investors/entrepreneurs, ensure stability and consistency in its macroeconomic policies, while monetary policy rates should be fixed in such a way that it would attract the right amount of investments in agriculture.

description: The subject of this paper is civil fraud, in particular as tortious conduct. Initially, in order to delimit the concept of civil fraud, its proposed definitions are approached and the conditions of article 147 of the Civil Code, in which fraud is regulated as a ground for avoidance of a contract, are presented. Next, the relationship between the two aspects of fraud, as a ground for avoidance and as a tort and, in particular, whether civil fraud is per se a tort is examined. Following these, the issue of due damages is approached in both cases regulated in article 149 of Civil Code, depending on whether the deceived confirms the contract or not. Finally, reference is made to the more specific issue of the possibility of reducing the damages, due to contributory negligence of the deceived

Publisher: name: Swinburne
Year: 2024

description: This thesis provides a detailed account of the construction of an apparatus to create and experimentally investigate a new state of matter known as a time crystal. Time crystals are a quantum physics phenomenon that can emerge in driven many-body systems where the system reorganizes its motion with a period longer than that of the driving force. These systems have the potential to reveal novel condensed matter phenomena in the time domain. Practical applications of time crystals could include advancements in quantum information processing, highly sensitive magnetic sensors and atomic clocks.

description: The effect of electron-nuclear spin interactions on qubit operations is investigated for a qubit represented by the spin of an electron localized in a self-assembled quantum dot. The localized electron wave function is evaluated within the atomistic tight-binding model. The magnetic field generated by the nuclear spins is estimated in the presence of an inhomogeneous environment characterized by a random nuclear spin configuration, by the dot-size distribution, by alloy disorder, and by interface disorder. Due to these inhomogeneities, the magnitude of the nuclear magnetic field varies from one qubit to another by the order of 100 G, 100 G, 10 G, and 0.1 G, respectively. The fluctuation of the magnetic field causes errors in exchange operations due to the inequality of the Zeeman splitting between two qubits. We show that the errors can be made lower than the quantum error threshold if an exchange energy larger than 0.1 meV is used for the operation.

Many statistical methods have been proposed in the past in order to describe the galaxy distribution and discriminate the different cosmological models. We present in this paper results relative to the use of new statistical tools using the 3D isotropic undecimated wavelet transform, the 3D ridgelet transform and the 3D beamlet transform. We show that such multiscale methods produce a new way to measure in a coherent and statistically reliable way the degree of clustering, filamentarity, sheetedness, and voidedness of a dataset

description: Methods and properties regarding the linear perturbations are discussed for some spatially closed (vacuum) solutions of Einstein's equation. The main focus is on two kinds of spatially locally homogeneous solution; one is the Bianchi III (Thurston's H^2 x R) type, while the other is the Bianchi II (Thurston's Nil) type. With a brief summary of previous results on the Bianchi III perturbations, asymptotic solutions for the gauge-invariant variables for the Bianchi III are shown, with which (in)stability of the background solution is also examined. The issue of linear stability for a Bianchi II solution is still an open problem. To approach it, appropriate eigenfunctions are presented for an explicitly compactified Bianchi II manifold and based on that, some field equations on the Bianchi II background spacetime are studied. Differences between perturbation analyses for Bianchi class B (to which Bianchi III belongs) and class A (to which Bianchi II belongs) are stressed for an intention to be helpful for applications to other models.

Applying concepts from chaos control theory we propose to control the spatio-temporal dynamics of fronts of accumulation and depletion layers which are generated at the emitter and may collide and annihilate during their transit, and thereby suppress chaos. The proposed method only requires the feedback of internal global electrical variables, viz current and voltage, which makes the practical implementation very easy.

description: We study the free motion of a massive particle moving in the background of a Finslerian deformation of a plane gravitational wave in Einstein's General Relativity. The deformation is a curved version of a one-parameter family of Relativistic Finsler structures introduced by Bogoslovsky, which are invariant under a certain deformation of Cohen and Glashow's Very Special Relativity group ISIM(2). The partially broken Carroll Symmetry we derive using Baldwin-Jeffery-Rosen coordinates allows us to integrate the geodesics equations. The transverse coordinates of timelike Finsler-geodesics are identical to those of the underlying plane gravitational wave for any value of the Bogoslovsky-Finsler parameter $b$. We then replace the underlying plane gravitational wave by a homogenous pp-wave solution of the Einstein-Maxwell equations. We conclude by extending the theory to the Finsler-Friedmann-Lemaitre model.

Year: 1978
Subjects: Labor and Human Capital

description: This paper investigates how the level of self employment effects the measurement of official unemployment statistics. The components of the unemployment rate are identified and the rate is recalculated to reflect the labor market performance for wage and salary workers only. Data from the Survey of Income and Education, conducted in 1976, are used to demonstrate that sub-national unemployment rates contain a systematic bias which is highly correlated with the level of self employed agricultural workers. After adjustment for self employment, rates increased by over 20 percent in nonmetropolitan areas and only 10 percent in metropolitan areas. The implications for manpower funding allocations resulting from this consistent understatement of rural unemployment rates are discussed.

DISTRIBUTION. Neotropical Region: Belize.
 COMMENTS. A. sapotae is the only species of the subfamily Aleyrodinae to have been described from Belize prior to the present study: its type locality was mistakenly quoted as being in [the Republic of] Honduras by Mound & Halsey (1978). It was described from a single specimen (Fig. 91). One species found in CFR during the present study (Aleuroparadoxus sp.1, fig. 92, Appendix 1) belongs to the A. sapotae ­group, as defined by Russell, but exhibits several differences—notably its indistinct submarginal papillae, fewer subdorsal cephalic modified papillae, and a pronounced pale double eyespot on each side of the cephalic region. A further member of the A. sapotae ­group is represented in BMNH by material from Costa Rica and Panamá.

Here, we explored patterns of introgression and signals of local adaptation in P. trichocarpa and P. balsamifera, employing genome resequencing data from three chromosomes in pure species and admixed individuals from wild populations. Local ancestry analysis in admixed P. trichocarpa revealed a telomeric region in chromosome 15 with P. balsamifera ancestry, containing several candidate genes for local adaptation. Genomic analyses revealed signals of selection in certain genes in this region (e.g. PRR5, COMT1), and functional analyses based on gene expression variation and correlations with adaptive phenotypes suggest distinct functions of the introgressed alleles. In contrast, a block of genes in chromosome 12 paralogous to the introgressed region showed no signs of introgression or signatures of selection. We hypothesize that the introgressed region in chromosome 15 has introduced modular, or cassette-like variation into P. trichocarpa. These linked adaptive mutations are associated with a block of genes in chromosome 15 that appear to have undergone neo- or sub-functionalization relative to paralogs in a duplicated region on chromosome 12 that show no signatures of adaptive variation. The association between P. balsamifera introgressed alleles with the expression of adaptive traits in P. trichocarpa supports the hypothesis that this is a case of adaptive introgression in an ecologically important foundation species.

description: We investigate how different magnetohydrodynamic models of propagation of a weak (Mach number ~1.2) shock in the core of a galaxy cluster affect its observational appearance, using the Perseus cluster as our fiducial model. In particular, we study how thermal conduction, both isotropic and anisotropic, and ion-electron temperature equilibration modify a weak shock. Strong thermal conduction is expected to produce an electron temperature precursor. Less prominent pressure and density precursors are formed as well. A longer equilibration time largely reduces the density precursor, but does not change the electron temperature precursor much. When thermal conduction becomes anisotropic, the intracluster magnetic field imprints its characteristic spatial scale on the distortions of the shock induced by heat fluxes.

Is There Too Much History in Historical Yield Data

description: County crop yield data from United States Department of Agriculture - National Agricultural Statistics Service has and continues to be extensively used in the literature as well as practice. The most notable practical example is crop insurance, as the Risk Management Agency uses the data to set guarantees, estimate premium rates, and calculate indemnities for their area programs. In many applications including crop insurance, yield data are detrended and adjusted for possible heteroscedasticity and then assumed to be independent and identically distributed. For most major crop-region combinations, county yield data exist from the 1950s onwards and reflect very significant innovations in both seed and farm management technologies; innovations that have likely moved mass all around the support of the yield distribution. Despite correcting for movements in the first two moments of the yield data generating process (dgp), these innovations raise doubt regarding the identically distributed assumption. This manuscript considers the question of how much historical yield data should be used in empirical analyses. The answer is obviously dependent on the empirical application, crop-region combination, econometric methodology, and chosen loss function. Nonetheless, we hope to provide some guidance by tackling this question in three ways. First, we use distributional tests to assess if and when the adjusted yield data may result from different dgps. Second, we consider the application to crop insurance by using an out-of-sample rating game -- commonly employed in the literature -- to compare rates from the full versus historically restricted data sets. Third, we estimate flexible time-varying dgps and then simulate to quantify the additional error when the identically distributed assumption is erroneously imposed. Our findings suggest that despite accounting for time-varying movements in the first two moments, using yield data more than 30 years past increases estimation error. Given that discarding historical data is unappetizing, particularly so in applications with relatively small T, we investigate three methodologies that re-incorporate the discarded data while explicitly acknowledging: (i) the retained and discarded data are from different dgps; and (ii) the extent and form of those differences is unknown. Our results suggest gains in efficiency may be realized by using these more flexible methodologies. While our results are most applicable to the crop insurance literature, we suggest proceeding with caution when using historical yield data in other applications as well.

description: Many agricultural households in developing countries depend on international migration and nonfarm work to cope with the economic risks and uncertainty associated with farming. We examine the effects of international migration and remittances on rural households’ participation in nonfarm jobs and the earnings generated from these jobs. Using data on agricultural households in Albania, results indicate that remittances received from migrant household members induce reallocation of household labor to nonfarm self-employment jobs, and increase income from at-home farming. Overall, international migration contributes to rural development in Albania through the positive impact of remittances on households’ ability to diversify income and reduce income risks associated with farming

description: The critical properties of $N$-color London model are studied in $d=2+1$ dimensions. The model is dualized to a theory of $N$ vortex fields interacting through a Coulomb and a screened potential. The model with N=2 shows two anomalies in the specific heat. From the critical exponents $α$ and $ν$, the mass of the gauge field, and the vortex correlation functions, we conclude that one anomaly corresponds to an {\it inverted} \xy fixed point, while the other corresponds to a \xy fixed point. There are $N$ fixed points, namely one corresponding to an inverted \xy fixed point, and $N-1$ corresponding to neutral \xy fixed points. This represents a novel type of quantum fluid, where superfluid modes arise out of charged condensates.

description: The delivery of a framework in place for secure application development is of real value for application development teams to integrate security into their development life cycle, especially when a mobile or web application moves past the scanning stage and focuses increasingly on the remediation or mitigation phase based on static application security testing (SAST). For the first time, to the author's knowledge, the industry-standard Open Web Application Security Project (OWASP) top 10 vulnerabilities and CWE/SANS top 25 most dangerous software errors are synced up in a matrix with Checkmarx vulnerability queries, producing an application security framework that helps development teams review and address code vulnerabilities, minimise false positives discovered in static scans and penetration tests, targeting an increased accuracy of the findings. A case study is conducted for vulnerabilities scanning of a proof-of-concept mobile malware detection app. Mapping the OWASP/SANS with Checkmarx vulnerabilities queries, flaws and vulnerabilities are demonstrated to be mitigated with improved efficiency.

Supersonic Discrete Kink-Solitons and Sinusoidal Patterns with "Magic" wavenumber in Anharmonic Lattices

description: The sharp pulse method is applied to Fermi-Pasta-Ulam (FPU) and Lennard-Jones (LJ) anharmonic lattices. Numerical simulations reveal the presence of high energy strongly localized ``discrete'' kink-solitons (DK), which move with supersonic velocities that are proportional to kink amplitudes. For small amplitudes, the DK's of the FPU lattice reduce to the well-known ``continuous'' kink-soliton solutions of the modified Korteweg-de Vries equation. For high amplitudes, we obtain a consistent description of these DK's in terms of approximate solutions of the lattice equations that are obtained by restricting to a bounded support in space exact solutions with sinusoidal pattern characterized by the ``magic'' wavenumber $k=2π/3$. Relative displacement patterns, velocity versus amplitude, dispersion relation and exponential tails found in numerical simulations are shown to agree very well with analytical predictions, for both FPU and LJ lattices.
