Food safety standards in the Guatemalan fresh pea sector: The role of financial literacy in technology adoption

The transformation of the global agrifood system is characterized by the increasing importance of food safety and quality standards. This trend is challenging farmers in countries like Guatemala as they lack necessary skills and assets. This study analyzes the determinants of Globalgap adoption with a special focus on financial literacy. The concept has not been considered yet in technology adoption studies. Our results indicate that financial literacy indeed has a significant impact on the probability to adopt the standard. Our results hold practical implications for development interventions targeting technology and standard adoption and smallholder market integration.
Development of a P 1 phagemid system for the delivery of DNA into Gram-negative bacteria

Department of Microbiology and Immunology, Medical University of South Carolina, 173 Ashley Avenue BSB-201, Charleston, SC 29403, USA The inability to transform many clinically important Gram-negative bacteria has hampered genetic studies addressing the mechanism of bacterial pathogenesis. This report describes the development and construction of a delivery system utilizing the broad-host-range transducing bacteriophage P1. The phagemids used in this system contain a P1 pac initiation site to package the vector, a P1 lytic replicon to generate concatemeric DNA, a broad-hostrange origin of replication and an antibiotic-resistance determinant to select bacterial clones containing the recircularized phagemid. Phagemid DNA was successfully introduced by infection and stably maintained in members of the families Enterobacteriaceae (Escherichia coli, Shigella flexneri, Shigella dysenteriae, Klebsiella pneumoniae and Citrobacter freundii) and Pseudomonadaceae (Pseudomonas aeruginosa). In addition to laboratory strains, these virions were used successfully to deliver phagemids to a number of strains isolated from patients. This ability to deliver genetic information to wild-type strains raises the potential for use in antimicrobial therapies and DNA vaccine development.
Some Speculative Hypotheses about the Nature and Perception of Dance and Choreography

Ever since I first saw a dance performance I have wondered why it is that I am sometimes fascinated and touched by some people moving about on a stage, while at other times it leaves me completely indifferent. I will argue that an answer to this question has to be searched for in the way sensory stimuli are processed in the brain. After all, all our actions, perceptions and feelings are mediated and controlled by the brain. The thoughts and feelings evoked by a dance performance are no exception and thus they too have a neural substrate in the brain. In music and the visual arts what has been called ‘neuroaesthetics’ (Zeki, 2001a) and ‘neuromusicology’ has already yielded some interesting insights. As one study showed, the aesthetic appeal of Mondrian’s paintings can be related to certain psychophysical properties of the visual system (Latto et al., 2000). Earlier studies had found that the perception of oblique lines is slightly inferior to the perception of horizontal and vertical lines. Making clever use of the fact that some of Mondrian’s paintings have an oblique frame, the authors showed that people also prefer horizontal and vertical to oblique lines. Findings like this suggest that we have an aesthetic preference for those stimuli that are closely tuned to the respective sensory areas in the brain. The present article draws an itinerary through various brain structures and shows how these may combine to ultimately give rise to the sensations we experience when watching a dance performance. Since watching dance is essentially a visual experience the present analysis concentrates on visual processing. This is not to deny that music is an integral part of most dance performances or that movements produce noise, which may influence visual processing and in the absence of a visual component elicit visual images. But, to state the obvious, if the stage lights go out the audience’s experience of the dancers’ movements will
Application of UAV Technology in Mapping Part of University of Uyo , Akwa Ibom , Nigeria

The products of aerial photogrammetry, such as, topographic map, DTM, etc., are usually acquired from very rigorous processes, expensive equipment, highly skilled personnel, longer period. This paper explores the application of Unmanned Aerial Vehicle (UAV) technology to solve the pitfalls associated with the traditional survey methods to generate improved terrestrial information, such as digital elevation models, orthophoto maps, etc. The UAV PHANTOM-4 equipped with a small format digital camera, Global Positioning System (GPS) and Inertial Navigation System (INS) was used to acquire digital aerial spatial information of part of University of Uyo Main Campus, in Akwa Ibom State, Nigeria. While HiTarget V30 GNSS RTK System was used to acquire ground control points (GCPs) within the area, and supported with Goggle Earth Imagery. The UAV data was processed with AGISOFT Photoscan Pro Software. The compared results from the generated ortho-rectified imagery with their corresponding RTK acquired ground control points revealed rmse of 0.00603m (6mm) and 0.00290m (3mm) for the planimetric and vertical coordinates respectively. The accuracies of the results further showed that the UAV system was reliable for cadastral surveying, mapping and the process was cost effective.
Confirmatory factor analysis on the measurement of five salutogenic constructs.

The aim of the research was to establish the factor structure of five salutogenic constructs in order to better understand the dynamics of salutogenic behaviour among university administrative staff. The behavioural constructs were sense of coherence, hardiness, selfefficacy, learned resourcefulness and potency. One measuring instrument per construct was administered on a random sample of 215 staff members. Strong inter-correlations were found between all the constructs. Confirmatory factor analysis indicated a three-factor structure consisting of sense of coherence/potency, hardiness/potency and selfefficacy/learned resourcefulness. The results confirmed firstly sense of coherence and secondly hardiness as separate constructs, potency as a supporting and self-efficacy/learned resourcefulness as a third generic construct. These findings could in future be used in the development of coping mechanisms by administrative staff during stressful times such as organisational change and transformation.
Using Task-Based Approach in Improving the Students ’ Speaking Accuracy and Fluency

This research aimed to find the improvement of the students’ speaking Accuracy and Fluency by using Taskbased Approach at SMA Negeri 2 Sungguminasa Kab. Gowa in the 2013/2014 Academic Year. Task-based Approach was used in a Classroom Action Research (CAR). The research had been conducted in two cycles, each cycle consist of four meetings. It employed speaking test as instrument. A number of research subjects were 37 students in class XI. The instruments were speaking test and observation. The research findings showed that Task-based Approach could improve the students’ speaking skill from cycle I to cycle II. The students’ achievement from D-Test to cycle I was 12.50%, and after finishing cycle II the students’ achievement became 16.27%. Based of the research findings, the researcher concludes that Task-based Approach gave a significant contribution in learning process of speaking accuracy and fluency.
Zooming into the Cosmic Horseshoe: new insights on the lens profile and the source shape

The gravitational lens SDSS J1148+1930, also known as the Cosmic Horseshoe, is one of the biggest and of the most detailed Einstein rings ever observed. We use the forward reconstruction method implemented in the lens fitting code Lensed to investigate with great detail the properties of the lens and of the background source. We model the lens with different mass distributions, focusing in particular on the determination of the slope of the dark matter component. The inherent degeneracy between the lens slope and the source size can be broken when we can isolate separate components of each lensed image, as in this case. For an elliptical power law model, $\kappa(r) \sim r^{-t}$, the results favour a flatter-than-isothermal slope with a maximum-likelihood value t = 0.08. Instead, when we consider the contribution of the baryonic matter separately, the maximum-likelihood value of the slope of the dark matter component is t = 0.31 or t = 0.44, depending on the assumed Initial Mass Function. We discuss the origin of this result by analysing in detail how the images and the sources change when the slope t changes. We also demonstrate that these slope values at the Einstein radius are not inconsistent with recent forecast from the theory of structure formation in the LambdaCDM model.

The Dynamics of the Racial Wealth Gap

What drives the dynamics of the racial wealth gap? We answer this question using a dynamic stochastic general equilibrium heterogeneous-agents model. Our calibrated model endogenously produces a racial wealth gap matching that observed in recent decades along with key features of the current cross-sectional distribution of wealth, earnings, intergenerational transfers, and race. Our model predicts that equalizing earnings is by far the most important mechanism for permanently closing the racial wealth gap. One-time wealth transfers have only transitory effects unless they address the racial earnings gap, and return gaps only matter when earnings inequality is reduced.
The first post‐injection seismic monitor survey at the Ketzin pilot CO2 storage site: results from time‐lapse analysis

The injection of CO2 at the Ketzin pilot CO2 storage site started in June 2008 and ended in August 2013. During the 62 months of injection, a total amount of about 67 kt of CO2 was injected into a saline aquifer. A third repeat three‐dimensional seismic survey, serving as the first post‐injection survey, was acquired in 2015, aiming to investigate the recent movement of the injected CO2. Consistent with the previous two time‐lapse surveys, a predominantly west–northwest migration of the gaseous CO2 plume in the up‐dip direction within the reservoir is inferred in this first post‐injection survey. No systematic anomalies are detected through the reservoir overburden. The extent of the CO2 plume west of the injection site is almost identical to that found in the 2012 second repeat survey (after injection of 61 kt); however, there is a significant decrease in its size east of the injection site. Assessment of the CO2 plume distribution suggests that the decrease in the size of the anomaly may be due to multiple factors, such as limited vertical resolution, CO2 dissolution, and CO2 migration into thin layers, in addition to the effects of ambient noise. Four‐dimensional seismic modelling based on dynamic flow simulations indicates that a dynamic balance between the newly injected CO2 after the second repeat survey and the CO2 migrating into thin layers and being dissolved was reached by the time of the first post‐injection survey. In view of the significant uncertainties in CO2 mass estimation, both patchy and non‐patchy saturation models for the Ketzin site were taken into consideration.
Pharmacoepidemiology of Common Poisoning Cases in Children at a Tertiary Care Teaching Hospital , Odisha , India

Acute poisoning caused more than 45 000 deaths in children and youth less than 20 years of age. Fatal poisoning rate is high in low and middle income countries like India. Childhood poisoning can be prevented with proper first aid, early management with appropriate treatment. On this background this study aimed to determine the demographic profile, pharmacotherapy and risk factors associated with fatal outcome in paediatric poisoning cases at a tertiary care teaching hospital. This descriptive cross sectional study had been conducted in the emergency department of paediatrics at M.K. C.G. Medical College and Hospital, Brahmapur, Odisha from March, 2016 to August, 2016. 105 paediatric poisoning cases of both the sexes were enrolled in this study with prior consent from parents. The protocol was approved by IEC. Relevant data were collected from hospital record and asking question to parents in a predesigned case record form. The categorical data were presented as percentage and risk factor association were analysed by Chisquare test. The children under 5years (57%) and males (67%) were predominantly affected. Maximum mortality observed i.e 25% with 1 month to 1 year age group. Rural area cases (84%) and accidental poisoning (93%) contributed the major share. Poisoning with biological agents (52.3%) with 93% cured rate. Urban cases could get earlier treatment than rural cases with 98% cure rate (p<0.01). The trends for paediatric poisoning cases attended to this centre were similar to other hospital based studies of India. Time lapsed to reaching the hospital was an important risk factor associated to mortality was observed. Establishment of poison information centre and raising public awareness would help in improving treatment outcome.
Phylogenyofthe 1-aminocyclopropane-1-carboxylic acid deaminase-encodinggeneacdS in phytobene ¢ cial and pathogenic Proteobacteria and relationwith strain biogeography

Deamination of the ethylene precursor 1-aminocyclopropane-1-carboxylic acid (ACC) is a key plant-beneficial trait found in plant growth-promoting rhizobacteria (PGPR) and phytosymbiotic bacteria, but the diversity of the corresponding gene (acdS) is poorly documented. Here, acdS sequences were obtained by screening putative ACC deaminase sequences listed in databases, based on phylogenetic properties and key residues. In addition, acdS was sought in 71 proteobacterial strains by PCR amplification and/or hybridization using colony dot blots. The presence of acdS was confirmed in established AcdS bacteria and evidenced noticeably in Azospirillum (previously reported as AcdS ), in 10 species of Burkholderia and six Burkholderia cepacia genomovars (which included PGPR, phytopathogens and opportunistic human pathogens), and in five Agrobacterium genomovars. The occurrence of acdS in true and opportunistic pathogens raises new questions concerning their ecology in plant-associated habitats. Many (but not all) acdS bacteria displayed ACC deaminase activity in vitro, including two Burkholderia clinical isolates. Phylogenetic analysis of partial acdS and deduced AcdS sequences evidenced three main phylogenetic clusters, each gathering pathogens and plant-beneficial strains of contrasting geographic and habitat origins. The acdS phylogenetic tree was only partly congruent with the rrs tree. Two clusters gathered both Betaprotobacteria and Gammaproteobacteria, suggesting extensive horizontal transfers of acdS, noticeably between plant-associated Proteobacteria.
Beta-dependent upper bound on ion temperature anisotropy in a laboratory plasma

Laser induced fluorescence measurements of ion temperatures, parallel and perpendicular to the local magnetic field, in the Large Experiment on Instabilities and Anisotropies space simulation chamber (a steady-state, high beta, argon plasma) display an inverse correlation between the upper bound on the ion temperature anisotropy and the parallel ion beta (β=8πnkT/B2). These observations are consistent with in situ spacecraft measurements in the Earth’s magnetosheath and with a theoretical/computational model that predicts that such an upper bound is imposed by scattering from enhanced fluctuations due to growth of the ion cyclotron anisotropy instability (the Alfven ion cyclotron instability).
An evaluation and comparison of Value at Risk and Expected Shortfall

As a risk measure, Value at Risk (VaR) is neither sub-additive nor coherent. These drawbacks have coerced regulatory authorities to introduce and mandate Expected Shortfall (ES) as a mainstream regulatory risk management metric. VaR is, however, still needed to estimate the tail conditional expectation (the ES): the average of losses that are greater than the VaR at a significance level These two risk measures behave quite differently during growth and recession periods in developed and emerging economies. Using equity portfolios assembled from securities of the banking and retail sectors in the UK and South Africa, historical, variance-covariance and Monte Carlo approaches are used to determine VaR (and hence ES). The results are back-tested and compared, and normality assumptions are tested. Key findings are that the results of the variance covariance and the Monte Carlo approach are more consistent in all environments in comparison to the historical outcomes regardless of the equity portfolio regarded. The industries and periods analysed influenced the accuracy of the risk measures; the different economies did not.
Vehicle Currency Pricing and Exchange Rate Pass-Through

Using detailed firm-level transactions data for UK imports, we find that invoicing in a vehicle currency is pervasive, with more than half of the transactions in our sample invoiced in neither sterling nor the exporter’s currency. We then study the relationship between invoicing currencies and the response of import unit values to exchange rate changes. We find that for transactions invoiced in a vehicle currency, import unit values are much more sensitive to changes in the vehicle currency than in the bilateral exchange rate. Pass-through therefore substantially increases once we account for vehicle currencies. This result helps to explain why UK inflation turned out higher than expected when sterling depreciated during the Great Recession and after the Brexit referendum. Finally, within a conceptual framework, we show why bilateral exchange rates are not suitable for capturing exchange rate pass-through under vehicle currency pricing. Overall, our results help to clarify why the literature often finds a disconnect between exchange rates and prices when vehicle currencies are not accounted for.
Dissonance-based Program for Eating Disorders Prevention in Mexican University Students

espanolEl objetivo de este trabajo fue identificar los cambios en el riesgo de desarrollar trastornos de la conducta alimentaria despues de un ano de seguimiento de un programa de prevencion basado en la tecnica de la disonancia cognitiva para trastornos de la conducta alimentaria. El Body Project fue implementado en una muestra de estudiantes universitarios, hombres y mujeres: 133, 110 y 74 en el pre-test, post-test y seguimiento, respectivamente. Se comprueba el cambio en las conductas alimentarias de riesgo (CAR) a lo largo del tiempo y segun las variables que, de acuerdo con el modelo teorico, se encuentran entre la intervencion y las CAR, con un analisis MANOVA de medidas repetidas para las asociaciones entre interiorizacion del ideal estetico de delgadez, los sintomas depresivos y las CAR. El valor promedio de las CAR en el pre-test fue 5.23, 3.45 en el post-test y 2.80 en el seguimiento. El modelo de las CAR como variable dependiente e interiorizacion del ideal estetico de delgadez y los sintomas depresivos como variables independientes mostro un efecto significativo de la internalizacion del ideal estetico de delgadez, F(2, 136) = 7.66, p = . 0011, mientras que no hubo un efecto significativo de los sintomas depresivos, F(2, 136) = 0.45, p = . 6191, lo que indica que la intervencion tuvo un efecto en las CAR por via de la variable antecedente. Se mostro que la intervencion produce efectos despues de un ano de seguimiento. Este hallazgo sustenta la implementacion de programas universales de prevencion que utilicen la tecnica de disonancia cognoscitiva. EnglishThe purpose of this study was to identify changes in the risk of eating disorders after a one-year follow-up of a dissonance-based eating disorders prevention program. The Body Project was implemented in a sample of male and female university students: 133, 110, and 74 at baseline, post-test, and follow-up respectively, and we tested the change in disordered eating behaviors (DEB) over time, and by levels of variables that according to the theoretical model lie on the path between the intervention and DEB, with one-way MANOVA analyses of repeated measures for the associations between internalization of the esthetic thin ideal, depressive symptoms, and DEB. The average value of DEB was 5.23 at pre-test, 3.45 at post-test, and 2.80 at follow-up. The model with DEB at each time point, as dependent variables, and internalization of the esthetic thin ideal and depressive symptoms, as independent variables, showed a significant effect of internalization of the esthetic thin ideal, F(2, 136) = 7.66, p = . 0011, while there was no significant effect of depressive symptoms, F(2, 136) = 0.45, p = . 6191, indicating that the intervention exerted its effect on DEB via the former variable. The intervention proved to produce effects after a one-year follow-up. These findings support the implementation of universal prevention programs using dissonance-based techniques.
Extensive NLoS Multiple NLoS Multiple Short NLoS CUBIC NewReno Scalable TCP Vegas Westwood YeAH

Millimeter-wave (mm-wave) bands will play an essential role in 5G mobile networks in supporting the increasing demand for higher data rates. Communications at mm-wave frequencies pose unique challenges. The high propagation loss and unfavorable atmospheric absorption make the channel quality highly variable – short communication ranges and blockage through obstacles may prevent communication altogether. The use of directional antennas helps to achieve higher communication ranges and provides better spatial reuse and lower interference compared to omni-directional communications. At the same time, this introduces the problem of beam misalignment. Mm-wave research has primarily focused on the PHY and MAC layers, whereas the transport layer aspects of mm-wave systems require further attention. In this article, we analyze the behavior of TCP in mm-wave networks and study its impact on systemlevel performance. Through extensive simulations, we show the effect of different types of blockages on the behavior of the congestion control in the presence of handovers, and when small, medium and long flows coexist. Protocols like CUBIC that target high throughput benefit significantly when jointly optimizing link layers buffers and timeouts. While the optimization fosters prompt reaction to short-term blockages, the performance of such protocols significantly decreases when obstacles degrade the channel quality for longer time periods. Hybrid-designs like TCP YeAH are more robust to blockage, but fail to recover quickly and to ramp up to the link capacity after timeouts.
