Agronomic performance of locally adapted sweet potato ( Ipomoea batatas (L) Lam.) cultivars derived from tissue culture regenerated plants

Tissue culture techniques have opened a new frontier in agricultural science by addressing food security and agricultural production issues. A study was conducted to compare growth and yield characteristics between the tissue culture regenerated and conventionally propagated sweet potato cultivars. Five locally adapted sweet potato cultivars Mugande, SPK004, Kemb10, Japon tresmesino and Zapallo were regenerated in vitro by the methods of indirect and direct embryogenesis and grown under field conditions in a RCBD replicated three times. Significant (P between the test cultivars and regeneration method for the growth and yield variables. The highest tuber numbers and marketable yield was recorded with Zapallo. Conventional propagation method gave highest growth rates however the difference in yield between the conventional propagation and tissue culture regenerated plants did not vary significantly (P ELISA established that field plants had a higher virus titre compared to the tissue culture regenerated plants.
Veno-venous ECMO for carbon dioxide removal in a neonate after Norwood operation with an RV-PA shunt

We describe a case of a newborn with a single-ventricle congenital heart defect, in which veno-venous extracorporeal membrane oxygenation (ECMO) was successfully employed shortly after a Norwood operation with right ventricle-to-pulmonary artery shunt due to pulmonary insufficiency.
Self‐Employment and Queues for Wage Work: Evidence from Chile

Self‐employment can be considered as either the result of a self‐selection process or a reflection of rigidities and skill mismatch in the labour market or both. We estimate a double selection model where individuals queue for wage work instead of being self‐employed in the first stage, followed by employers selecting from the queue in the second. We find statistical support for the double selection model, implying that some individuals are self‐employed because they cannot find wage work, while other self‐select to be self‐employed. Individuals with higher education are more often chosen as wage workers, and belonging to an ethnic group decreases the likelihood of being chosen. Additionally, earnings equations suggest that high ability individuals perform better in both the wage work and self‐employment sectors. Copyright © 2015 John Wiley & Sons, Ltd.
Segmenting Consumers Based on Their Evaluation of Local, Global and Glocal Brands

Abstract Based on their evaluations, attitudes, and purchase intention towards global, local, or glocal brands, this article provides and understanding of different consumer segments, in an emerging economy, suggesting theoretical, and practical implications for marketers and provides additional contributions to the literature on this area. The results of two surveys conducted in Mexico, suggest that the profile of “global brand lovers” is high consumer cosmopolitanism, low ethnocentrism, young, and low price sensitive. However, “local brand lovers” also have a higher level of cosmopolitanism than ethnocentrism. Finally, we empirically identified that materialism is the dominant consumer attitudinal disposition among “glocal brand lovers. ”
Reactive collisions between electrons and NO+ ions: rate coefficient computations and relevance for the air plasma kinetics

Extensive calculations of the rate coefficients for dissociative recombination (DR), elastic collisions, inelastic collisions (ICs) and superelastic collisions of NO+ ions on initial vibrational levels, , with electrons of energy between 10−5 and 10 eV have been performed, with a method based on multichannel quantum defect theory. Comparisons of the DR rate coefficients with the plasma experimental results give a good agreement, confirming that the vibrationally excited NO+ ions recombine more slowly than those in the ground state. Also, our ground state IC rate coefficients are very similar to previously computed R-matrix data. The rate coefficients have been fitted to a modified Arrhenius law, and the corresponding parameters are given, in order to facilitate the use of the reaction data in kinetical plasma modelling.

Feasibility of partial replacement of discarded filamentous green seaweed (Cladophora) with commercial feed in spotted scat (Scatophagus argus) culture

An 60-day feeding experiment was conducted to investigate the effects of partial replacement of discarded filamentous green seaweed (Cladophora) with commercial feed on the growth performance and feed efficiency of spotted scat (Scatophagus argus). Triplicate groups of fish with initial body weight of 3.31 -3.39 g were reared in the 250 L plastic tanks at salinity of 5 g L-1. Results showed that growth rate of fish in the alternate feeding regime, 1 day commercial feed and 1 consecutive day dried or fresh green seaweed were not significantly different (p>0,05) from the control group received single commercial feed.
Finite Element Analysis of Debonded Sandwich Beams Under Axial Compression

A nonlinear finite element analysis was performed to simulate axial compression of sandwich beams with debonded face sheets. The load-end-shortening diagrams were generated for a variety of specimens used in a previous experimental study. The energy release rate at the crack tip was computed using the J-integral, and plotted as a function of the load. A detailed stress analysis was performed and the critical stresses in the face sheet and the core were computed. The core was also molded as an isotropic elastic-perfectly plastic material and a nonlinear post buckling analysis was performed. A Graeco-Latin factorial plan was used to study the effects of debond length, fact sheet and core thicknesses, and core density on the load carrying capacity of the sandwich composite. It has been found that a linear buckling analysis is inadequate in determining the maximum load a debonded sandwich beam can carry. A nonlinear post-buckling analysis combined with an elasto-plastic model of the core is required to predict the compression behavior of debonded sandwich beams.
Push or Pull: Imitation vs. Emulation in Great Apes and Human Children

All four species of great apes and young human children (12–24 mo of age) were administered an imitation task designed to distinguish between results learning (emulation) and action learning (imitation). Some subjects were exposed to a demonstrator either pushing or pulling a door to open a box, whereas others simply saw the door of the box opening itself in one of the two directions (the ghost control). Most of the apes successfully opened the box in both experimental conditions, as well as in a baseline condition, but without being influenced either by the demonstrator’s actions or by the door’s motions. In contrast, human children over 12 mo of age were influenced by the demonstration: the 18-mo-olds were influenced by the demonstrator’s actions, and the 24-mo-olds were influenced both by the demonstrator’s actions and by the door’s motions in the ghost control. These results provide support for the hypothesis that human children have a greater propensity than great apes for focusing either on a demonstrator’s action or on the result of their action, as needed, in social learning situations.

Let M be a module over a ring R, which satisfies the ascending chain condition on submodules of the form TV: B c N: B 2 c N: B 3 c • for every submodule N of M and every finitely generated ideal B of R. We investigate the class of such modules M and show that various important properties of Noetherian modules and rings can be generalized to modules and rings of this class.
Properties of young contrails – a parametrisation based on large-eddy simulations

Abstract. Contrail–cirrus is probably the largest climate forcing from aviation. The evolution of contrail–cirrus and its radiative impact depends not only on a multitude of atmospheric parameters, but also on the geometric and microphysical properties of the young contrails evolving into contrail–cirrus. The early evolution of contrails (t
Rainfall characteristics, runoff rate and traffic flow on gully morphometric parameter growth and soil loss in sand-mined peri-urban, Uyo, Nigeria

The number of rain days, rainfall amount, intensity and erosivity, runoff rates and traffic count influenced soil losses or degradation of gully morphometric parameters of length, width and depth, and semi-circular ratio (SCR) and contributed significantly (p<0.01) to gully initiation and growth in sandmined peri-urban. 42 gullies in 42.80 m 2 were studied, indicating that gully initiation and development on sand-mined land use in periurban was very intense. Rill/gully erosion initiation was more severe from the onset of rains in March to June than from July to August. June experienced high rainfall intensity, the most erosive rain and the highest gully frequency (21%) in the study area. June to August accounted for 57% of all gully frequencies, which correlated significantly (p <0.01) with runoff discharge (r = 0.811) and traffic count (r = 0.811) and their combined increase led to increased frequency or number of gullies developed. Highest monthly gully frequency (52%) occurred at the middle of the slope with 10, 21 and 17% frequencies at upper, lower slopes and valley sections respectively gully erosion grew by the degradation of the individual morphometric parameters of length, width and depth severally. The only 2nd order gully widened to increase gully growth and soil loss while the 1st order gullies lengthened to achieve gully growth and soil loss. For the 2nd order gully with final stage depth/width (D/W) ratio of 2.20, total soil loss was 155.00T per year.
Management as a Technology?

Are some management practices akin to a technology that can explain company and national productivity, or do they simply reflect contingent management styles? We collect data on core management practices from over 11,000 firms in 34 countries. We find large cross-country differences in the adoption of basic management practices, with the US having the highest size-weighted average management score. We present a formal model of "Management as a Technology", and structurally estimate it using panel data to recover parameters including the depreciation rate and adjustment costs of managerial capital (both found to be larger than for tangible non-managerial capital). Our model also predicts (i) a positive effect of management on firm performance; (ii) a positive relationship between product market competition and average management quality (part of which stems from the larger covariance between management with firm size as competition strengthens); and (iii) a rise (fall) in the level (dispersion) of management with firm age. We find strong empirical support for all of these predictions in our data. Finally, building on our model, we find that differences in management practices account for about 30% of cross-country total factor productivity differences.
Relationship between Gender Diversity on Boards and Firm’s Performance - Case Study about ASEAN Banking Sector

By using the data collected from 70 largest banks in the ASEAN banking system in period from 2009 to 2013, the authors try to investigate the impacts of gender diversity in the board of managements (BOM) and board of directors (BOD) of corporate business on bank’s performance in ASEAN banking system. Firm’s performance is measured by return on assets (ROA) and return on equity (ROE). This analysis is done through descriptive statistics, correlation test and regression analysis. Research’s result show that both percentages of women on board of managements have a significant and positive impact on firm’s performance while percentage of women on boards of directors has a neutral effect on firm’s performance in Malaysia. Besides, the results in this study is also relevant with total assets which is a control variable had positive impact on firms’ performance. From these findings, this study also suggested that managerial and legislative efforts be balanced gender to more female candidates, on both board of director and top executive, order to gain better corporate governance.
Natural dynamic backgrounds affect perceived facial dominance

We have tested whether natural dynamic backgrounds affect perceived facial dominance. Facial evaluation is based on just two fundamental dimensions of facial appearance: valence and dominance. Perceived facial valence has been shown to be biased towards background valence. However, it is currently unknown, if the perception of facial dominance is also context dependent. In this study, participants rated the perceived dominance of neutral faces superimposed on everyday dynamic backgrounds that were either classified as low (weak) or high (strong) in dominance. Neutral faces were perceived as significantly more dominant when seen on a strong dynamic background than on either a weak or neutral background. Thus, background dominance enhances perceived facial dominance. Since dynamic textures are ubiquitous this finding is relevant for the design and experience of both our daily environment and multimedia content.
EFL LEARNERS’ ATTITUDES TOWARDS THE IMPROVEMENT OF THEIR ENGLISH SPEAKING PERFORMANCE

This study aims to describe EFL learners’ attitudes towards the improvement of their English speaking performance. The data were collected through a questionnaire distributed to 131 students of Department of English Language Education. The results of the data analysis show that all respondents show positive attitudes towards the improvement of their English speaking performance. Although female students have more positive attitudes than male students, the difference is not significant. The results also show that students’ attitudes towards their speaking performance change in accordance with their learning time. Their self-assessment of their speaking performance has a significant correlation with their attitudes. Their positive attitudes towards the improvement of their English speaking performance serve as a foundation to the success of the English language learning. Therefore, learners should pay attention to and maintain attitudes to improve their speaking performance.

Autonomous learning in neuromorphic systems for recognition of spatio-temporal spike patterns

Spiking neuromorphic devices rely on the fact that spikes are an e cient mechanism for encoding and transmitting spatio-temporal properties of stimuli. Several neuromorphic sensors have been built recently that e ciently encode dynamic stimuli into spikes in real-time. But detecting stimuli based on the information embedded in such spikes in real-time is still an open problem. Typically, the problem of detection of stimuli based on spatio-temporal spike patterns is reduced to detection of coincident spiking activity in the spike pattern. The ordering of spikes and the precise Inter-Spike Intervals (ISIs) are often ignored thereby loosing precious temporal information such as causality in the stimulus. These approaches also require very precise tuning of parameters to match the properties of the input spike patterns. In order to recognize spike patterns based on their temporal properties, I investigate alternate strategies for spike based neural processing. I propose a novel model, that exploits spike propagation delays and the temporal properties of Spike Timing Dependent Plasticity (STDP) to capture the spatio-temporal correlations in the spike pattern. This allows the model to go beyond detecting simply the coincidences in the stimuli. The model relies on a pool of propagation delays that enable neurons in the network to store precise inter-spike intervals in the target spike pattern. Through STDP the network converges to a connectivity that encompasses the ISIs corresponding to the target spike pattern. To ensure its robustness to imprecise neuromorphic devices, it is validated by implementing and testing it on a neuromorphic multi-chip system. The intrinsic transistor mismatch of neuromorphic devices is exploited to generate a wide range of propagation delays with point Leaky Integrate and Fire (LIF) neurons. By training the network on a parameterized set of synthetically generated spike patterns, it is demonstrated that the model can learn to di erentiate between di erent spike patterns even if they share the same spatial properties but have di erent temporal properties. This work enables us to build spike-based neuromorphic systems that perform real-time learning and detection based on the spatio-temporal properties of the stimulus. The generality of this work to generic spike patterns enables us to perform challenging tasks such as multi-sensory fusion and to learn relevant spatio-temporal correlations across multiple sensory modalities.

Extracts of Japanese Quince Seeds - Potential Source of Antioxidants

Japanese quince ( Chaenomeles japonica ) is a minor fruit crop in Latvia and Lithuania; it is used for production of juice, aroma and fruit fibers. The seeds are by- products of food processing that could be used furt her for different purposes. The seeds of Japanese quince co ntain about 10 to 20% of oil. The composition of th is oil is quite unique: nearly 90% of it is formed by two fat ty acids - linoleic (52.4%) and oleic (35.6%). We h ave also found out that the extracts of Japanese quince seed s can be used to improve stability of vegetable oil s ‐ 10 wt-% additive of ground seeds to hempseed oil and 5 wt-% additive to rapeseed oil can increase the oxidativ e stability of these oils about 2.0 and 1.6 times, respectively . Unfortunately, the seeds of Japanese quince conta in also amygdalin ‐ toxic cianogenic glycoside. Due to this compound the usage of seeds of Japanese quince are very limited, especially in case of their hydrophilic ex tracts. Our research was focused on hydrophilic ext racts of seeds in order to find out both the best method to prepare polyphenols rich extracts, as well as to de termine the amount of toxic amygdalin in the ethanol/water extr acts of seeds and in the extracted seeds. We have f ound out that the largest amount of total polyphenols can be obtained when whole seeds are extracted with the mixture of ethanol and water under reflux.
Did the EBA Capital Exercise Cause a Credit Crunch in the Euro Area?

We exploit a unique monthly dataset of bank balance sheets to document the lending behaviour of euro area banks that were subject to the EBA's 2011/12 Capital Exercise. This exercise was announced in October 2011 and required large European banking groups to meet a higher Tier 1 capital ratio by June 2012, after accounting for an unprecedented temporary buffer against exposure to sovereign debt. Controlling for bank characteristics and demand at the level of country of residence, we find that banks in a banking group that had to increase its capital by 1 percent of risk-weighted assets tended to have annualized loan growth (over the 9 month period of the exercise) that was between 1.2 and 1.6 percentage points lower than for banks in groups that did not have to increase their capital ratio. Looking at aggregate effects at the country level, we also find that banks that did not have to recapitalize did not substitute for more constrained lenders. Our results are of particular relevance for the decisions facing the new European Single Supervisor in advance of its Asset Quality Review due in November 2014.
