Market access, intensification and productivity of Common bean in Ethiopia: a microeconomic analysis

This work analyses on-farm adjustments in land allocation and intensification in a commercial crop following the increases in market demand in a developing economy. Drawing from the survey conducted among common bean producers in Ethiopia in 2008, a two stage econometric method was used to investigate the contribution of market access and other micro-level factors in facilitating crop intensification and productivity. Ethiopia is the leading commercial producer and exporter of common bean in Africa but also one of the countries in Africa with high levels of soil nutrient depletion. Understanding factors that influence input use and productivity is critical for food security and agricultural sustainability in the country. Based on farm survey data, it was shown that most farmers had expanded their area under common bean but the use of fertilizer and improved varieties was still low. Increase in the intensity of fertilizer and seed use produces an increase in yield and so is market access. Market access has intensification as well as specialization effects on common bean yield. Access to credit, extension and household wealth are other factors that facilitate common bean intensification while risk increasing factors constrain it. Key words: Common bean, intensification, productivity, Ethiopia.
The Price Discovery Mechanism between Sovereign Bond and Sovereign CDS Market: Studies in Selected Countries

This paper employs the multivariate VAR model to examine the mechanic work of price discovery process between sovereign CDS market and the associated sovereign bond market in contexts of five European and Asian countries, including Vietnam, Korea, Portugal, Italy and France from the beginning of 2008 to the end of April, 2017. The study accentuates on three aspects: the short-term interaction nexus between the sovereign CDS and the associated-sovereign bond market, the long-term co-movement between them and the discovery of which market plays the leading role in the pricing process. The results evidence the short-run and long-run relationship for the two markets. Particularly, the empirical test results support for the predominant role of the sovereign CDS market in the price discovery process in the bulk of sample entities. This might suggests for the governments to use CDS prices as the future indicator for predicting the volatility of debt markets.
Process Techno-Innovation Using TQM in Developing Countries Empirical Study of Deming Prize Winners

Techno-innovation has been competitive edge for most manufacturing companies. Rapid advancement in technologyinnovation geared-up with global mega-competition has resulted in unprecedented economic growth where TQM has played major role. Despite slow economic growth in developing countries caused by incapability to develop their own technology, failure to make wise decision in adopting competent technology, and inability to properly utilize adopted technologies; tremendous developments are seen in some. Examples can be Indian companies that won the prestigious Deming Prize and Japan Quality Medal after adopting necessary technologies from Japan under TQM. We have addressed process techno-innovation by 4M (Man, Machine, Method, Material) and 1E (working condition-corporate culture) approach. Results indicate that TQM affects process techno-innovation by primary effect on human resource and working condition/corporate culture. Three stage gates vis-a-vis: process understanding, process improvement and technology learning, and process techno-innovation are the mechanisms through which TQM promotes process techno-innovation in developing countries.
Moderating Role Of Trust On Relationship Between Formalization And Perceived Organizational Support

As perceived organizational support (POS) has been found to have a strong impact on some important organizational outcomes such as performance, organizational commitment, and job satisfaction, a bundle of research has recently been tried to shed light on discovering the antecedents of POS. Thus, this study attempts to identify the effect of formalization, as one of the important dimension of organizational structure, on POS by evaluating the moderating role of trust in organization. The survey of this study is conducted on 343 administrative support staff, who works for airline industry. In order to understand the moderating effect of trust between formalization and POS, hierarchical moderated regression analysis has been employed. The results reveal that formalization positively and significantly affects perceived organizational support, while trust in organization moderates this relationship. More specifically, this relationship will be stronger when trust in organization is high. In other words, the relationship between formalization and POS will be weaker when trust in organization is low. Furthermore, the results are discussed and some suggestions for future research are proposed. © 2017 Published by Future Academy www.FutureAcademy. org.UK
Effect of environmental and genetic factors on the correlation and stability of grain yield components in wheat

More effective breeding and development of new wheat genotypes depend on an intricate analysis of the complex relationships among many different traits. The objective of this paper was to determine the interrelationship, direct and indirect effects, and stability of different yield components in wheat. Forty divergent genotypes were analyzed in a three- year study (2005-2007). Highly significant correlations were found between grain yield per plant and all the other traits analyzed except spike length, with the only negative correlation being that with plant height. Path analysis revealed highly significant direct effects of grain number per spike, grain mass per spike and 1000 grain weight on grain yield per plant. Analysis of stability parameters showed that the stability of grain yield per plant depended for the most part on the stability of grain number per spike, grain mass per spike and harvest index. Cluster analysis identified genotypes with a high performance for grain yield per plant and good stability parameters, indicating the possibility of developing wheat varieties with a high potential and high stability for a particular trait.

Statistical Analysis on the Design of Flow Modifying Centre-Bodies in a Plenum Chamber

The primary objective of this study is to numerically investigate the influence of various geometries of flow modifying centre-bodies on the aerodynamics of flow in the plenum chamber of a swirling fluidized bed. Ten different hub geometries, in the shape of cylinder, cone, conical frustum or a combination of these are considered in the study. Two performance characteristics of interest are flow uniformity at the exit plane of the plenum chamber and the total pressure drop across the plenum. The homogeneity of airflow was assessed from a statistical analysis conducted. From the results, it is evident that the introduction of a full-length cylindrical hub at the centre of the plenum chamber offers a balance in the required performance characteristics.
EEG-Based Automatic Sleep Stage Classification

Sleep disorders have a great impact in the patients’ quality of life. The study of human sleep during the different sleep stages is crucial in the diagnosis of sleep disorders and is mainly performed with polysomnography (PSG). In this work, a methodology for sleep staging using solely Electroencephalographic (EEG) signals from PSG recordings is presented. EEG signals from the ISRUC-Sleep dataset are selected and used, aiming to automatically identify the five sleep stages. Initially, the EEG signal is filtered in order to extract the five EEG rhythms and the energy is calculated in each sub-band and used to train several typical classifiers. Results in terms of classification accuracy reached 75.29% with Random Forests.
Influence of lake basin morphology on recent sedimentation rates based on the example of Lake Raduńskie Górne, N Poland

Abstract The study relates to the use of the 210Pb method for determining sedimentation rates, sedimentation accumulation rates and identifying post-depositional processes. The analysis was based on seven cores of recent sediments collected from different parts of Lake Raduńskie Górne, which is a typical channel lake with diverse bottom morphology. We used alpha spectrometry to determine 210Pb activities in sediment samples and a CF:CS dating model to obtain mean sediment accumulation rates. The results show significant differences between coring sites with highest values in the deepest part of the lake and lowest within the shallow and flat bottom areas. The reason for such a large diversity is the lake basin morphology, e.g. steep slopes and complex configuration of the lake bottom, most probably responsible for the post-depositional sediment replacements.
THE INTRODUCTION OF THE COMMON CURRENCY IN SLOVENIA

The inflation in the first and half year after the introduction of Euro in Slovenia was of a short-term nature, conditioned also by a favorable economic growth. The cumulative (retail) price level growth was also conditioned by internal factors (a weak competition in certain sectors and an increase in domestic demand) and external factors (some originate from the increase in food and energy product prices on the world market and from relative high GDP growth in Slovenia due to export growth) in the observed time period.
RELATIONSHIP BETWEEN PHYSICAL SELF-CONCEPT AND PHYSICAL ACTIVITY AMONG ADOLESCENTS RELACIONES ENTRE EL AUTOCONCEPTO FÍSICO Y LA ACTIVIDAD FÍSICO-DEPORTIVA ADOLESCENTE

The aim of this study is to test two opposing models of the relationship between physical self-perceptions and physical activity during adolescence: one which postulates that physical activity influences physical self-concept, and another one which proposes that physical self-concept influences physical activity. Participants were 704 students aged between 11 and 19 (M = 14.91; SD = 2.13) from two different Autonomous Regions in Spain (Cantabria and the Basque Rev.int.med.cienc.act.fís.deporte vol. 16 número 63 ISSN: 1577-0354 562 Country). 394 (55.96%) were male and 310 (44.04%) were female. The results indicate that the influences between physical self-concept and physical activity are bidirectional in nature, although the model that proposes physical selfconcept as an influencing factor was found to have a better fitness. Differences were found in the model between male and female students. Furthermore, selfperception of physical attractiveness was found to be negatively related to physical activity.
A Review on Internet Use and Quality of Life of the Elderly.

As the world population rapidly ages, improving the quality of life (QOL) of the elderly and enabling them to age actively is increasingly becoming a global policy concern. In this context, emphasis is also given to information and communication technologies (ICTs) that may play a significant part in enhancing the QOL of the elderly. This review study explores the impact of Internet use on QOL of the elderly by examining available researches in this field. By searching on ADM Digital Library, WEB Science, ERIC, PsycINFO and PubMed databases, this study reviewed 25 studies published after 1990 that investigate the relationship between Internet use and QOL of elderly. The synthesis of the research findings indicates that the functional use of computer and Internet improves QOL for older people. The findings also provide a comprehensive perspective on the current state of knowledge and raises questions for further research. Keywords: e lderly, Internet use, quality of life
Center for Financial Studies

We examine the effects of credit default swaps (CDS), a major type of over-thecounter derivative, on the corporate liquidity management of the reference firms. CDS help firms to access the credit market since the lenders can hedge their credit risk more easily using these contracts. However, CDS-protected creditors can be tougher in debt renegotiations and less willing to support distressed borrowers, causing some firms to become more cautious. Consequently, we find that firms hold significantly more cash after the inception of CDS trading on their debt. The increase in cash holdings by CDS firms is more pronounced for financially constrained firms and firms facing higher refinancing risk. Moreover, bank relationships and outstanding credit facilities intensify the CDS effect on cash holding. Finally, firms with greater financial expertise hold more cash when their debt is referenced by CDS. These findings suggest that CDS, which are primarily a risk management tool for lenders, induce firms to adopt more conservative liquidity policies. ∗We thank Lauren Cohen, Miguel Ferreira, Andrea Gamba, Robin Greenwood, Jarrad Harford, Victoria Ivashina, Andrew Karolyi, Beni Lauterbach, Kai Li, Chen Lin, Tse-chun Lin, Ron Masulis, Joshua Pollet, Henri Servaes, Laura Starks, René Stulz, Toni Whited, and seminar and conference participants at the University of Hong Kong, the University of Warwick, the University of Münster, the 2012 NTU International Conference on Finance, the 2012 SFM Conference at the National Sun Yat-sen University, the 2013 European Finance Association Meetings, and the 2014 Jerusalem Finance Conference for helpful comments on previous drafts of this paper.

Algebraic structure count of linear phenylenes

The algebraic structure count (ASC) is a concept introduced into theoretical organic chemistry by WilCOX1,2, following earlier work of Dewar and Longuet-Higgins3. It is based on the idea that each individual Kekule structure of a conjugated molecule has a "parity"3. Then ASC is equal to the difference between the number of "even" and the number of "odd" Kekule structures. This quantity was shown4,s to play an important role in determining the Jr-electron properties of polycyclic conjugated compounds. In particular, if ASC = 0 then the respective rr-electron system has an openshell configuration and is thus extremely unstable (and nonexisting in the great majority of cases)3-S. The thermodynamic stability of conjugated hydrocarbon compounds increases with the increasing ASC-value6,7.
Wesselsite, SrCu[Si4O10], a further new gillespite-group mineral from the Kalahari Manganese Field, South Africa

Abstract Wesselsite, SrCu[Si4O10], is a new mineral species from the Wessels mine, Kalahari Manganese Field, South Africa, and it belongs to the gillespite group. Wesselsite is tetragonal, space group P4/ncc; the unit cell parameters, refined from Gandolfi film data, are a = 7.366(1), c = 15.574(3)Å , V = 845.01 Å3. The strongest lines are (dobs/Iobs/hkl) (7.79/35/002), (4.33/20/112), (3.89/20/004), (3.44/40/ 104), (3.33/100/202), (3.12/55/ 114), (3.03/50/212), (2.68/25/204), (2.61/30/220) and (2.32/30/116). Wesselsite is associated with hennomartinite, embedded in a matrix of sugilite, xonotlite, quartz and pectolite. Microprobe analyses of 111 samples show that it is the end-member of a solid solution series with effenbergerite, BaCu[Si4OH10], with substitutions of Sr by Ba up to 50 mol. %. Wesselsite forms tiny subhedral plates in sizes not exceeding 50 × 50 × 5 μm, arranged in clusters of up to 200 μm. It shows a perfect cleavage parallel to {001 }, has blue colour, white to light blue streak, and is uniaxial negative with ω= 1.630(2), Ɛ= 1.590(5), strongly pleochroic from blue (ω) to pale blue (Ɛ). The calculated density is 3.32 g cm−3, the measured density is 3.2(1) g cm−3.
Working Paper Series Department of Economics University of Verona Redistribution at the Local Level : The Case of Public Childcare in Italy

We study the determinants of redistribution at the municipal level in the context of public childcare in Italy. Within a substantially homogeneous legislative framework, different municipalities autonomously define how participation fees vary with a compound indicator of income and wealth (ISEE), thus redistributing resources across households using the service. The nearly one hundred municipalities we take into account exhibit wide heterogeneity in redistributive attitudes. We find statistically significant correlations of these with a number of individual characteristics of policy-makers and municipalities, but not with those of the ex-ante distribution of income, which should be central according to both normative and positive theory. Since the price of public childcare is subsidized, resources are also redistributed from tax-payers to users. The evidence that we find is consistent with the hypothesis that this type of redistribution is a public good.

New reaction rates for improved primordial D/H calculation and the cosmic evolution of deuterium

Primordial or big bang nucleosynthesis (BBN) is one of the three historically strong evidences for the big bang model. Standard BBN is now a parameter-free theory, since the baryonic density of the Universe has been deduced with an unprecedented precision from observations of the anisotropies of the cosmic microwave background radiation. There is a good agreement between the primordial abundances of He4, D, He3, and Li7 deduced from observations and from primordial nucleosynthesis calculations. However, the Li7 calculated abundance is significantly higher than the one deduced from spectroscopic observations and remains an open problem. In addition, recent deuterium observations have drastically reduced the uncertainty on D/H, to reach a value of 1.6%. It needs to be matched by BBN predictions whose precision is now limited by thermonuclear reaction rate uncertainties. This is especially important as many attempts to reconcile Li observations with models lead to an increased D prediction. Here, we reevaluate the d(p,γ)He3, d(d,n)He3, and d(d,p)H3 reaction rates that govern deuterium destruction, incorporating new experimental data and carefully accounting for systematic uncertainties. Contrary to previous evaluations, we use theoretical ab initio models for the energy dependence of the S factors. As a result, these rates increase at BBN temperatures, leading to a reduced value of D/H=(2.45±0.10)×10-5 (2σ), in agreement with observations.
Self-Esteem of Deaf and Hard of Hearing Compared with Hearing Adolescents in Slovenia - the Context of Social and Communication Factors

Objective: The study focuses on the self - esteem of deaf and hard of hearing (D/HH) and hearing adolescents (HA) in Slovenia. The aim of this study is a comparison of self - esteem between D/HH and HA regarding the hearing status, age, gender, and the com parison among D/HH adolescents regarding communication and education settings. It is hypothesized that deaf and hard of hearing adolescents hav e lower self - esteem than their hearing peers. Methods: The final sample included 130 adolescents who were split into two groups with the method of equal pairs: 65 D/HH adolescents and 6 5 HA, which were esta blis hed on the basis of gender, age, nationality, and educational programme of schooling. The phenomenon of self - esteem was measured with the Rosenberg Self - Esteem Scale, which was translated and adapted into the Slovenian Sign Langu age (SSL). Results: The results show significant differ ren - ces in self - esteem between D/HH and HA adolescents. D/HH adolescents have, on average, lower self - esteem than HA. There are differences in self - esteem regarding gender and also regarding ages of 16 and of 20. D/HH adolescents who use speech or sign language in their communication have higher self - esteem than those who use mostly sign language. D/HH adolescents in mainstream schools have hig her self - esteem than those included into a segregated form of schooling. Discussion: There are differences among adolescents in how they view themselves. Self - esteem can be a significant predictor of life satisfaction. Conclusion: D/HH adolescents experie nce lower self - esteem when compared with HA peers.
