description: This study examined the profitability and efficiency of small scale ginger production in selected Local Government Areas of Kaduna State using data collected through personal interview schedules with structured questionnaire. Results from the study showed that majority (96.0%) of ginger farmers are male with an average age and farming experience of 42 and 27 years respectively. Majority of the respondents (82.5%) are married and possess an average farm size of 3.09hectares. The average household size is 7 and up to 46% of them acquired secondary education. The results also revealed that labor, seed, fertilizer and capital inputs were significant in explaining the output. The mean technical efficiency of 0.799 indicate that an average ginger farmer in the study area will enjoy an output increase of 18.55% if management techniques are improved and he attains the level of the most efficient ginger farmer. Among the various factors affecting inefficiency, farm size and extension contact accentuated inefficiency while access to credit suppressed inefficiency. This might be an indication that the two parameters that encouraged inefficiency were over-employed. Hence, in order to attain the production frontier of the most efficient farmer, farm size should be scaled down or additional quantity of other inputs should be employed. Price fluctuation, unavailability of farm input, poor remunerative price and poor access to credit are the major constraints faced by ginger farmers in the study area. There is need for policies aimed at encouraging extension education, commercial farming, access to credit, and transport facilities.

description: Access to credit significantly influences land leasing decisions, and thus ultimately has a significant implication on ensuring efficiency in agricultural production. This paper attempts to examine the instrumental role of credit in ensuring efficiency in the context of West Bengal agriculture by disaggregating the analysis for two mutually exclusive groups: bank customers and non-bank customers. Empirical analysis based on Stochastic Frontier Analysis confirms that farming households having access to formal credit are, in general, practicing cultivation more efficiently by channelizing credit in the utilization of agricultural inputs. In addition, contractual arrangements and operated farm size are found to be significant determinants of observed variation of technical efficiency estimates in case of bank customers. In the context of higher probability of access to credit in case of fixed rent tenants and large farmers, it can be argued that farmers having access to credit achieved a higher efficiency level by adopting the improved technology in agricultural production. Thus an access to institutional credit would provide an incentive to the farmers to adjust the operational land by the mechanism of tenurial contract so as to bring about efficiency in agricultural production.

description: This paper uses household level data collected from November 2010 to December 2011 for 303 respondents to examine probable determinants of poverty status employing descriptive analysis and Probit models. The descriptive result of mean per capita food expenditure (MPKFE) in ZobaMaekel of Eritrea found that all the households’ heads are poor. The result of Probit analysis shows that poverty status is strongly associated with almost all variables used. Education level, type of resident, size of land, number of meal, remittance, access of credit from relatives, credit institutions, opinion to credit, rain fed crop, irrigated crop, income from agriculture and income from -non-agriculture were found to be negatively associated with food self-sufficiency as a proxy of poverty. However, family number, number of children, children at school age and rent of land highly positively related to poverty. For instance, higher levels of educational attainment will provide higher levels of welfare for the household. Education is not sufficient condition to escape from poverty. This indicates that there are other factors which affect poverty of a household in conjunction with education. There is a need for providing complementary factors alongside with education to alleviate poverty. Remittance is a good indicator of poverty, showing strong family ties within Eritrean society, the fact that Eritrea does not have social security system it may help to pursue policies which foster cultural ties and family networks as part of poverty alleviating endeavor. Polices to enhance social capital should be stressed more.

description: We present non-trivial interactions of N=1 self-dual massive vector multiplet in three-dimensions, with gauged scale covariance. Our multiplets are a vector multiplet (A_μ, λ) and a gauge multiplet (B_μ, χ), where the latter is used for the gauging of the scale covariance of the former. Due tothe absence of supergravity, this system has no lagrangian formulation, but has only a set of field equations. The gauge multiplet can also have Dirac-Born-Infeld type interactions, even in the presence of the massive self-dual vector multiplet. As a by-product, we also show that scale covariant couplings are possible for scalar multiplet. We also try a mechanism of spontaneous breaking of scale covariance by introducing a superpotential for scalar multiplets.

description: The absence of isotropic singularity in loop quantum cosmology can be understood in an effective classical description as the universe exhibiting a Big Bounce. We show that with scalar matter field, the big bounce is generic in the sense that it is independent of quantization ambiguities and details of scalar field dynamics. The volume of the universe at the bounce point is parametrized by a single parameter. It provides a minimum length scale which serves as a cut-off for computations of density perturbations thereby influencing their amplitudes.

description: Efimov states are known to have a discrete real space scale invariance, working in momentum space we identify the relevant discrete scale invariance for the scattering amplitude defining its Weierstrass function as well. Through the use of the mathematical formalism for discrete scale invariance for the scattering amplitude we identify the scaling parameters from the pole structure of the corresponding zeta function, it's zeroth order pole is fixed by the Efimov physics. The corresponding geometrical fractal structure for Efimov physics in momentum space is identified as a ray across a logarithmic spiral. This geometrical structure also appears in the physics of atomic collapse in the relativistic regime connecting it to Efimov physics. Transforming to logarithmic variables in momentum space we map the three-body scattering amplitude into Bloch states and the ladder of energies of the Efimov states are simply obtained interms of the Bohr-Sommerfeld quantization rule. Thus through the mapping the complex problem of three-body short range interaction is transformed to that of a non-interacting single particle in a discrete lattice.

description: Rice is an economically important food security crop, cultivated in almost all of Nigeria’s 36 States. Nigeria spends more than 356 billion naira (2.24 billion US dollars) annually on rice import. This paper set out to analyze the trend in rice production, productivity, import, value of import and consumption that follows the adoption of the Structural Adjustment Programme (SAP) in Nigeria, with emphasis on the effects of exchange rate (ER) deregulation on domestic rice production and rice imports over the period 1986-2010. Relevant time series data were collected and used. A semi-log growth rate model and 2simple linear regression models were developed and estimated. Highlights of the findings include (i) accelerated rate of growth in rice production (Instantaneous Growth Rate (IGR) 2.2%; Cumulative Growth Rate (CGR) 2.2%); rice hectarage (IGR 3.7%; CGR 3.8%); rice importation (IGR 8.5%; CGR8.9%); expenditure on rice importation (IGR 10.6%; CGR 11.2%) and rice consumption (IGR 3.4%; CGR 3.5%) alongside a significant deceleration in rice yield (IGR -1.4%; CGR -201.4%) (ii) The observed significant increase in domestic rice production cannot be confidently attributed to ER deregulation alone because it does not lead to a decrease in rice importation into Nigeria. (iii) The significant increase in domestic rice importation as observed contradicts a priori expectation that ER deregulation will lead to significant decrease in rice importation. The study concluded that free market approach alone cannot stimulate local agricultural production in countries where farmers producing under low-technology-agriculture are put in direct competition with farmers from advanced-technology-agriculture; hence governments need to restrict importation to protect local producers

description: Most countries across the globe, particularly in the developing world, continue showing a failure to implement anti-corruption reforms in line with national and international commitments. This situation is especially disheartening when the amount of resources the international community has poured into them is considered, as well as the level of academic interest and production this issue has attracted. Thus, a core question has remained unanswered: What is holding back the fight against corruption? In the present study, a theoretical model to understand the support and opposition to anti-corruption reforms, and the identification of strategies available to international and domestic actors, is developed following a systems approach. The model suggests that different patterns of stress on the political system, together with the availability of a variety of strategies to stimulate political support, make governmental actors able to resist reform even on the face of societal and international pressure.

description: We have calculated the optical conductivity and the Raman response for the d-density wave model, proposed as a possible explanation for the pseudogap seen in high Tc cuprates. The total optical spectral weight remains approximately constant on opening of the pseudogap for fixed temperature. This occurs because there is a transfer of weight from the Drude peak to interband transitions across the pseudogap. The interband peak in the optical conductivity is prominent but becomes progressively reduced with increasing temperature, with impurity scattering, which distributes it over a larger energy range, and with ineleastic scattering which can also shift its position, making it difficult to have a direct determination of the value of the pseudogap. Corresponding structure is seen in the optical scattering rate, but not necessarily at the same energies as in the conductivity.

description: Fine-tuning is a popular way of exploiting knowledge contained in a pre-trained convolutional network for a new visual recognition task. However, the orthogonal setting of transferring knowledge from a pretrained network to a visually different yet semantically close source is rarely considered: This commonly happens with real-life data, which is not necessarily as clean as the training source (noise, geometric transformations, different modalities, etc.). To tackle such scenarios, we introduce a new, generalized form of fine-tuning, called flex-tuning, in which any individual unit (e.g. layer) of a network can be tuned, and the most promising one is chosen automatically. In order to make the method appealing for practical use, we propose two lightweight and faster selection procedures that prove to be good approximations in practice. We study these selection criteria empirically across a variety of domain shifts and data scarcity scenarios, and show that fine-tuning individual units, despite its simplicity, yields very good results as an adaptation technique. As it turns out, in contrast to common practice, rather than the last fully-connected unit it is best to tune an intermediate or early one in many domain-shift scenarios, which is accurately detected by flex-tuning.

description: The study analyzed income inequality and poverty dynamics among rural farm households in Abia State, Nigeria. Beyond the broad objective, the study sought specifically to estimate the income distribution and determine the poverty line, gap and incidence of the rural farm households. A total of 240 households were selected across the agricultural zones using multistage sampling technique from which data and information were elicited. Data collection was between 2010 and 2011. Analytically, the study employed Gini coefficient in the estimation of income distribution while poverty indicators (Mean household income, headcount ratio and poverty gap index) were used to measure poverty line, poverty incidence and gap. Income distribution showed high level of inequality (Gini index = 0.987) with per capita income falling below the operational national minimum wage. The poverty gap and incidence gave a scary picture of worsening poverty situation, judging from the poverty indicators (head count index = 0.567; poverty gap = 0.568). To reverse the trend, it is important that concerted efforts are made by way of policy direction to ensure that the rural economy which is largely agrarian is improved. This can be achieved by adopting input subsidy, private sector driven market access policy, labour intensive techniques in execution of public projects among others
Pleiotropy robust methods for multivariable Mendelian randomization

Subjects: subject: Methodology (stat.ME)

description: Mendelian randomization is a powerful tool for inferring the presence, or otherwise, of causal effects from observational data. However, the nature of genetic variants is such that pleiotropy remains a barrier to valid causal effect estimation. There are many options in the literature for pleiotropy robust methods when studying the effects of a single risk factor on an outcome. However, there are few pleiotropy robust methods in the multivariable setting, that is, when there are multiple risk factors of interest. In this paper we introduce three methods which build on common approaches in the univariable setting: MVMR-Robust; MVMR-Median; and MVMR-Lasso. We discuss the properties of each of these methods and examine their performance in comparison to existing approaches in a simulation study. MVMR-Robust is shown to outperform existing outlier robust approaches when there are low levels of pleiotropy. MVMR-Lasso provides the best estimation in terms of mean squared error for moderate to high levels of pleiotropy, and can provide valid inference in a three sample setting. MVMR-Median performs well in terms of estimation across all scenarios considered, and provides valid inference up to a moderate level of pleiotropy. We demonstrate the methods in an applied example looking at the effects of intelligence, education and household income on the risk of Alzheimer's disease.

description: Les graines de tomates sont les constituants majeurs des déchets de l’industrie de transformation des fruits de tomate, elles représentent 0,5%du poids du fruit et contiennent entre 18 et 30% de lipides sous forme d’huile. L’objet de ce travail est l’extraction et la caractérisation de l’huile de graine de tomate. Les graines de tomate proviennent d’un tas de déchet en stockage au niveau de la conserverie Ammour – Mouzaîa – Algérie. Après séparation, triage et séchage à l’air libre, les graines sont placées dans un dispositif Soxhelet contenant le n-hexane comme solvant d’extraction. Le rendement à l’extraction a été calculé, il est de 209,86 grammes d’huile pour 934,06grammes de graines de tomate, soit 22,47% ; après filtration le rendement est de 21,6%, soit 82%des lipides présent dans les graines de tomate. Les constantes physicochimiques caractéristiques de la qualité des huiles ont été mesurées avant et après raffinage de l’huile extraite ; il en ressort que le raffinage diminue l’acidité de 0,9 à 0,06%, la teneur en chlorophylle de 15,46 à 0,0092 ppm et entraine la disparition du phosphore. Les autres constantes mesurées n’ont pas subi de variation notable. Les résultats de l’analyse chromatographique de la fraction lipidique de l’huile de graines de tomate raffinée a révélé un profil chromatographique composé de 07 acides gras à 16 et 18 atomes de carbones. Les acides linoléiques et oléiques sont prédominants avec 52 et 22% respectivement. Les acides gras saturés sont représentés essentiellement par 13,18% d’acide palmitique et par de la résistance à l’oxydation de l’huile de graines de tomate extraite est de 4,70 heures à la température de 120°C, correspondant à une durabilité de 223 jours à 20°C.

AbstractEpi proColon® is a blood-based colorectal cancer (CRC) screening test that presents a convenient, non-invasive option for CRC screening in average-risk adults aged ≥ 50 years who are otherwise non-compliant to guideline-recommended screening programs. The Epi proColon test involves the use of a real-time PCR assay to detect methylated Sept9 DNA (a biomarker for CRC) in plasma derived from a whole blood sample. Epi proColon generally performed well in prospective clinical trials, having non-inferior sensitivity for detecting CRC compared with a fecal immunochemical test (FIT). Microsimulation modeling supports annual Epi proColon testing, as for FIT. Although the Epi proColon test specificity is lower than that of a FIT, the Epi proColon test may be useful for improving participation and compliance in CRC screening, as evidenced in a small randomized controlled clinical trial which showed that uptake of an offer of an Epi proColon blood test was significantly higher than that for a FIT in subjects who were overdue for CRC screening.

Cette étude vise à évaluer l’impact de cette activité de production de semence sur la productivité et le revenu des producteurs au Bénin. Pour éliminer le biais lié à la différence dans les caractéristiques des adoptants et des non-adoptants, la méthode de Local Average Response Function (LARF) basée sur l’approche contrefactuelle a été utilisée pour estimer l’effet moyen local du traitement (LATE). La collecte des données a porté sur 240 riziculteurs dont 128 producteurs de semences sélectionnés de façon aléatoire. Les résultats montrent que la rentabilité de la production de semence (441 980 FCFA/ha) est environ deux fois celle du riz de consommation (249 410 FCFA/ha). De plus, la production de semence a permis d’augmenter le rendement du riz de 1924 kg/ha d’améliorer leur revenu des ménages agricoles de 92 572 FCFA/ha. Cette étude suggère la mise en place des innovations institutionnelles qui proposent des premiums sur le prix du riz mais exigeante sur la qualité de l’offre pour non seulement améliorer la qualité du riz local mais aussi le revenu des ménages agricoles.

description: Spätestens seit Lemnitzer / Zinsmeister (2015: 13) gilt die Definition von Korpus als einer Sammlung schriftlicher oder gesprochener Äußerungen in einer oder mehreren Sprachen in digitaler Form. Das wissenschaftliche Programm der Korpuslinguistik am Leibniz-Institut für Deutsche Sprache, welches das aktuell größte Korpus in deutscher Sprache vorhält, ist daher auch, „geleitet durch die explorative Analyse von sehr großen Sammlungen natürlichsprachlicher Daten neue Einsichten in die Strukturen, Gesetzmäßigkeiten, Eigenschaften und Funktionen von Sprache zu erlangen“. (https://www.idsmannheim.de/digspra/kl/, 17.10.2021.) Seine Verantwortlichkeit liegt dabei darin, „den deutschen Schriftsprachgebrauch beständig und in angemessener Weise stichprobenartig im Deutschen Referenzkorpus zu dokumentieren“ (ebd.). Das Deutsche Referenzkorpus DeReKo bildet mit aktuell 50,6 Milliarden Wörtern (Stand 02.02.2021) die weltweit größte linguistisch motivierte Sammlung elektronischer Korpora und beinhaltet geschriebene Texte in deutscher Sprache aus der Gegenwart und der neueren Vergangenheit. Die Daten sind über die Korpusrecherchetools COSMAS II und KorAP kostenlos abfragbar und können als Basis für multiple linguistische Fragestellungen verwendet werden (https://www.ids-mannheim.de/digspra/kl/projekte/korpora/, 17.10.2021).
Electron properties of carbon nanotubes in a periodic potential

description: A periodic potential applied to a nanotube is shown to lock electrons into incompressible states that can form a devil's staircase. Electron interactions result in spectral gaps when the electron density (relative to a half-filled Carbon pi-band) is a rational number per potential period, in contrast to the single-particle case where only the integer-density gaps are allowed. When electrons are weakly bound to the potential, incompressible states arise due to Bragg diffraction in the Luttinger liquid. Charge gaps are enhanced due to quantum fluctuations, whereas neutral excitations are governed by an effective SU(4)~O(6) Gross-Neveu Lagrangian. In the opposite limit of the tightly bound electrons, effects of exchange are unimportant, and the system behaves as a single fermion mode that represents a Wigner crystal pinned by the external potential, with the gaps dominated by the Coulomb repulsion. The phase diagram is drawn using the effective spinless Dirac Hamiltonian derived in this limit. Incompressible states can be detected in the adiabatic transport setup realized by a slowly moving potential wave, with electron interactions providing the possibility of pumping of a fraction of an electron per cycle (equivalently, in pumping at a fraction of the base frequency).

description: Regardless of the progress made in the past two decades by the international anti-corruption movement in terms of its financial, technical, and human resources, the implementation of effective policies by national governments have rarely been in line with their discursive and legal commitments. Furthermore, literary progress on the subject has been hard pressed to find feasible solutions to the lack of political will hindering the adoption of domestic anti-corruption reforms. The present study addresses this issue by reinterpreting the meaning of political will for domestic anti-corruption activities, positing that anti-corruption, contrary to most other types of policies, cannot be stimulated solely by the promise of political support for reformist leaders: rather, it responds to the leadership’s calculus of both political capital and illegal profits. In other words, anti-corruption is only possible when it is appealing to the particular interests of a specific set of political leaders. This approach is tested by assessing the Peruvian experience with the adoption of a National Anti-Corruption Plan between 2001 and 2013. The empirical analysis shows that, contrary to the international emphasis on technical assistance as a vehicle for change, the attempts to adopt a national plan to fight corruption in Peru have closely followed the state and evolution of political events, driven mostly by the necessity to stimulate support for the incumbent party while also kept from affecting the status quo. At the end, the study concludes that the characteristics of the political leadership and context were the primary force behind any symbolic or genuine efforts to elaborate an official National Anti-Corruption Plan, which, notwithstanding its recurrent emergence in the government agenda, has yet to be institutionalized as a proper mechanism to support the fight against public malfeasance.
Investigation of the role of comA in uptake signal sequence recognition in Haemophilus influenzae
Creators: name: Bertrand, Melanie Anne Alexandra
Publisher: name: University of British Columbia
Year: 2010

description: Haemophilus influenzae is a naturally competent bacterial species that preferentially takes up conspecific DNA. It recognizes this DNA by a nine base pair Uptake Signal Sequence (USS) that is over-represented in its own genome. The mechanism by which this USS is recognized is unknown, though knockout mutations in several genes have been shown to eliminate both binding and uptake of DNA. One of these genes may be involved in binding the USS. I attempted to determine if comA, one of the candidate genes, was responsible for the sequence specific binding. This gene was amplified under mutagenic PCR conditions, and then used to transform a hypercompetent strain of H. influenzae, using a novobiocin resistant PCR amplified marker sequence to identify transformants. Transformants were then screened for a reduction in transformation frequency to identify possible mutants. comA from these lines was then sequenced and compared to the known wild type sequence. None of the mutant lines differed in the sequence of comA in comparison to the known wild type, so no conclusions may be drawn concerning the role of comA. Mapping these mutations was beyond the scope of this project; however, a possible explanation for the reduced transformation frequency phenotypes is described here. Four isolates retained their phenotypes under competence inducing conditions, indicating a change in binding efficiency. None of the isolates possessed a reversion of the hypercompetent parental genotype.

description: Due to the exponential increase in the number and quality of empirical corruption studies spawned from the introduction of quantitative instruments, some necessary theoretical aspects of the phenomenon have somehow fallen behind in the academic agenda. One such example of empirical attention without proper conceptual construction is the case of ‘corruption tolerance’, or the acceptance and support of corrupt activities. The present study sets out to trace the emergence and employment of corruption tolerance as an academic concept, and building on past literature proposes a vertical accountability approach that operationalizes it on behavioral (or action-based) terms as opposed to previous attitude-centered approaches: Citizens must be able to accurately perceive corruption when relevant information is available, adjust their opinions of the involved actors according to that information, and punish in some way the corrupt actors. Failure to reach any of these steps results in the citizen’s behavioral adherence to condone the corrupt behavior of the political actor. To test the extent of the consequences of this departure from attitudes, an empirical indicator of high-level corruption tolerance based on the voting behavior of citizens in the 2006 presidential elections in Peru is constructed, and ordered logistic regression analysis is employed to address the effects of attitudes over behavior regarding high-level corruption. The results show that ‘attitudes’ only marginally affect an individual’s behavior, and hence they can best be understood as one among other determinants of corruption tolerance. This result highlights the necessity to reevaluate the implications for policy implementation of previous studies on the subject.

description: La presente investigación se focaliza en medir la bioeconomía de Nicaragua utilizando el enfoque canadiense de la economía bio-basada, siguiendo las sub-categorías de Sistema de Clasificación Industrial Norteamericano (NACIS). Los datos y registros disponibles en el Banco Central de Nicaragua registrados en el Sistema de Cuentas Nacionales fueron utilizados para homologar las subcategorías del NACIS y el Clasificador Industrial Internacional Uniforme (CIIU) revisión 3 de las Naciones Unidas que permitió homologar los principales componentes de la economía bio-basada. El año base de referencia fue 1994 para el periodo 1994-2000 y 2006 como año de referencia para el 2006-2007. Los resultados evidencian que la Bioeconomía contribuyó al PIB en un 28 % durante el periodo 1994-2000, en cambio durante el nuevo año de referencia 2006 se estimó un 7 % en promedio consistente con las estimaciones de Pellerin [24]. De los componentes principales se destacó la industria de química orgánica con un 74% y 75 % respectivamente, durante el periodo 2006-2007. En segundo orden el componente de las actividades de agricultura y cultivos con una contribución del 22%, para el periodo 2006-2007, pero represento el primer orden para el periodo 1994-2000 y el componente de salud, industrias médicas y farmacéuticas representó una contribución de un 24 % durante el periodo 1994-2000, pero no así para el siguiente periodo, que al igual que los alimentos y bio-procesos de bebidas tienen una baja contribución.

description: Excerpts from the report: The primary intent of this study was to determine where marketing practices could be strengthened to improve marketing efficiency, and thus to increase returns to farmers as patrons of cooperatives. It is also necessary to be sure that commercial users can depend on cooperative manufacturers for a supply of dry milk that meets their specific needs. As far as can be determined, this is the first study that combines an analysis of the experiences and practices of manufacturers with a study of the experience of users. Eleven cooperatives and 20 commercial users were selected for the study. The 11 cooperatives selected for study accounted for approximately one-third of the total U.S. production of nonfat dry milk.

description: We establish strict upper limits for the Casimir interaction between multilayered structures of arbitrary dielectric or diamagnetic materials. We discuss the appearance of different power laws due to frequency-dependent material constants. Simple analytical expressions are in good agreement with numerical calculations based on Lifshitz theory. We discuss the improvements required for current (meta) materials to achieve a repulsive Casimir force.
