Mathematical Problems in Creating Large Astronomical Catalogs

Published: March 2017

The next stage after performing observations and their primary reduction is to transform the set of observations into a catalog. To this end, objects that are irrelevant to the catalog should be excluded from observations and gross errors should be discarded. To transform such a prepared data set into a high-precision catalog, we need to identify and correct systematic errors. Therefore, each object of the survey should be observed several, preferably many, times. The problem formally reduces to solving an overdetermined set of equations. However, in the case of catalogs this system of equations has a very specific form: it is extremely sparse, and its sparseness increases rapidly with the number of objects in the catalog. Such equation systems require special methods for storing data on disks and in RAM, and for the choice of the techniques for their solving. Another specific feature of such systems is their high “stiffiness”, which also increases with the volume of a catalog. Special stable mathematical methods should be used in order not to lose precision when solving such systems of equations. We illustrate the problem by the example of photometric star catalogs, although similar problems arise in the case of positional, radial-velocity, and parallax catalogs.

Published: March 2017

The kinematic parameters of the Galactic disk are redetermined based on open-cluster data. It is shown that the Bottlinger-Oort model of pure circular rotation can be confidently used to describe the observed motions of disk objects at least out to heliocentric distances of 3.5 kpc.
Radial Velocity Dispersions of Star Groups in M67
Authors: Vereshchagin S. V. , Chupina N. V.
Published: March 2017

High-precision measurements of radial velocities of the M67 cluster members are used to calculate the radial-velocity dispersions in the stellar groups found earlier in the cluster’s corona. The previously detected feature in one of the groups (Group 60) consisting of stars with almost identical space velocities was confirmed. The possibility of more accurate future studies of the parameters of star groups using the Gaia catalogues is discussed.

Are Central Banks In CEE Countries Concerned About The Burden Of Public Debt?
Authors: Mackiewicz-Łyziak Joanna
Published: March 2017

The aim of this study is to analyze the monetary policy rules in the Czech Republic, Hungary and Poland, with public debt as an additional explanatory variable. We estimate linear rules by the GMM estimation and non-linear rules, using the Markov-switching model. Our findings suggest that in the Czech Republic and Poland the monetary authorities respond to growing public debt by lowering interest rates, while in Hungary the opposite may be observed. Moreover, we distinguish between passive and active monetary policy regimes and find that the degree of interest rate smoothing is lower and the response of the central banks to inflation and/or output gap is stronger in an active regime. In the passive regime, the output gap seems to be statistically insignificant.
The Social Effects Of The Economic Transformation In India (An Attempt At Measurement and Evaluation)
Authors: Bywalec Grzegorz
Published: March 2017

One of significant and, at the same time, challenging research problems in Economics is measuring the social effect of economic growth (development). Economic growth should never be treated a goal per se. It is rational provided that it brings effects such as, generally speaking, an improvement in the standard of living. However, this is not always the case. Social sciences, including Economics, have not developed any uniform methods of measuring and evaluating such effects yet. This paper constitutes an attempt to measure and evaluate the social effects of the reforms of the Indian economy and state launched in 1991. The analysis covers a period of over twenty years. As a result of the aforementioned reforms, at the beginning of the second decade of the 21st century, India ranked third in the world in terms of GDP (based on purchasing power parity), after the USA and China. So what are the social effects of such a dynamic economic growth? For the purposes of this paper, in order to quantify and evaluate the social effects of the economic growth in India and its dynamics in the analysed time period, the author experimentally adopts a popular socio-demographic index, i.e. the average further life expectancy (e0). This constitutes the so-called natural aggregate (a micro index) applied in social development analyses. It is quite commonly used by Indian economists and statisticians, albeit it is rarely applied in European Economics. The empirical analysis of the trends in the said index proves that the rapid economic growth in India after the year 1991 has brought about substantial increases in the life expectancy of the inhabitants of the country and a diminishing of disparities in this regard on a national scale (in different cross-sections: urban-rural, females-males, as well as in the regional perspective). In the mid-2010s India is almost on a par with the countries with a medium development rate in terms of the life expectancy of its inhabitants and in some states (e.g. Kerala). the value of this index is comparable to that in the highly developed countries.
GA3 Assisted Seed Dormancy Breaking in Abelmoschus moschatus Medik. subsp. moschatus
Authors: Gogoi G. , Borua P.K. , Chetia D.
Published: March 2017

Abelmoschus moschatus Medik. subsp. moschatus is a wild uncultivated variety of common lady’s finger (Abelmoschus esculentus) possessing a high degree of seed dormancy. Methods of dormancy breaking in the seed of the plant were investigated through different physical and chemical methods. Different preconditioning treatments including hot water, dry heat, physical scarification and chemical treatments including exogenous GA3 were applied to explore the initiation in germination. Seeds were germinated under the controlled photoperiod and temperature. The viability of the test seeds was estimated by topographical 2, 3, 5-Triphenyltetrazolium chloride (TTC) solution test. Highest germination percentage was obtained in the seeds treated with the exothermic reaction of H2SO4 and H2O, followed by exposure to gibberellic acid (GA3). The exposure time of exogenously applied GA3 had a significant influence on the germination response. The optimum germination temperature was found to be 30 ± 0.5°C. Treatment with 0.75% of 2, 3, 5-Triphenyltetrazolium chloride solution for 4 h at 35 ± 0.5°C enabled to correlate the viability of the seeds with the germinative values. Maximum germination was induced through this technique and dormancy of the seed can be attributed due to hard impermeable seed coat and endogenous physiological factor.

Published: March 2017

This study aims to evaluate the effect of seed priming for two pepper varieties by extracts of two algae thalli on the performance of growth at vegetative stage. The seeds were soaked in thalli aqueous extracts (at 20, 40, 60, 80 and 100 g/L), for 24 h at 28±2°C, rinsed thoroughly with distilled water and then dried to their initial weight as a first batch (SD), a second batch of seeds was considered, corresponding to seeds placed in Petri dishes to germinate directly after washing (SND). Untreated seeds were the control. The results showed than the priming has improved seedlings growth for both varieties. Seed priming with algae aqueous extracts has improved roots and shoots length. The best stimulations were 220% and 70%, respectively, recorded for seedlings of Baklouti and Chargui varieties, following the priming with the extract ofPadina pavonicaat 40 g/L concentration. These improvements appear to be related to a better photosynthetic intensity, an increase in the number of leaves and the water content, which were noted in plants from pretreated seeds. Finally, the results indicate that, generally, the plantlets from SND were more vigorous. The results of this work show that algae could be an inexhaustible resource of substances, that can be used as an alternative to chemicals used in the pretreatment of seeds, reducing the risk of pollution and preserving the biological material.

Published: March 2017

Potato crop is affected by numerous diseases in field, as well as in storage conditions, particularly in cold storage. Dry rot of potato is caused by Fusarium sp. Dry rot of seed tubers can reduce crop establishment by killing developing potato sprouts, and crop losses can be up to 25%, while more than 60% of tubers can be infected in storage. It is a rich source of energy, which supplement food source of a country. In this experiment, four systemic and four non-systemic fungicides were tested at different concentrations in vitro for their comparative efficacy against inhibition of the growth of Fusarium sp. through poisoned food technique. To manage these diseases effectively, different concentrations of fungicides were tested. Results revealed against Fusarium sp. that carbendazim and benomyl significantly inhibited the fungal growth even at its lower concentration (100 ppm) and proved statistically superior over the rest of the fungicides tested at different concentrations and among non-systemic fungicides, MEMC significantly inhibited the fungal growth even at its lower concentration (1000 ppm).
Dialogic catharsis in standup comedy: Stewart Huff plays a bigot
Authors: Seizer Susan
Published: March 2017

This essay investigates the cathartic creative process of a standup comic who recounts, in a video-taped interview with the author, the act of transforming a painful meeting with a bigot in a bar into the stuff of comedy. Through reflexive engagement with his own creative process, Stewart Huff recounts building a scenario that splits his experience into two voices, enacting a breakthrough into performance within the taped interview itself. Taking to heart Bakhtin’s insight that parody involves a hostile relation between the speaker and another, and that introducing someone else’s words into our own speech results in a double-voiced narrative, I analyze Huff’s performance as a classic example of double-voiced parody. The transformation from horror to humor is an empowering performative re-creation for the comedian that serves simultaneously as humorous recreation for the comedy club audience. This essay contributes to extant scholarship on the efficacious use of parodic double-voicing and the possibilities it opens up for dialogic catharsis in comedic performance.
The Effectiveness of Vacuum-microwave Drying Methods in the Preservation of Amelanchier Berries (Amelanchier canadensis L. Medik.)

Published: March 2017

In Poland, Amelanchier berries are of considerable interest to both consumers and potential producers, which presents marketing challenges and opportunities. An attempt was made to preserve Amelanchier berries using a vacuum-microwave method of drying in order to determine its usefulness for producing microbiologically stable dried fruit with a high nutritional values. The berry variety “Prince William” (Amelanchier canadensis) was chosen as the experimental material. Vacuum-microwave drying was performed in two variants: (convective drying [CD] + vacuum microwave method [VMW]) after convective pre-drying of fruit and (VMW) without pre-drying. Unassisted CD was used as the reference method. Application of a vacuum-microwave drying method to Amelanchier berries makes it possible to obtain a stable preserved product of high-quality, yielding moderate shrinkage and good retention of bioactive compounds. An optimized method of vacuum-microwave drying, applied directly to frozen fruit, allows the retention of 70 % of cyanidin glycosides present in the raw material.
On the determination of transformation parameters between different ITRS realizations using Procrustes approach in Turkey
Authors: Yetkin Mevlut , Ansari Kutubuddin
Published: March 2017

The International Terrestrial Reference Frame (ITRF) solutions that are published by the International Earth Rotation and Reference Systems Service (IERS) are annual realizations of the ITRS (International Terrestrial Reference System). The results expressed in two different ITRS realizations can be compared using the transformation parameters that provide a link between different ITRF solutions. Generally, the 7-parameter (the three translation parameters, three rotation parameters and one scale factor) Helmert transformation is employed to compute the transformation parameters. However, the number of transformation parameters can be increased for better understanding. For example, 3 different scale factors may be computed instead of one scale factor. In this paper, the 9-parameter (the three translation parameters, three rotation parameters and three scale factors) transformation model and its solution by Procrustes approach is considered. Transformation parameters between ITRF 05 and ITRF 08 for Turkey have been computed in both 7-parameter model and 9-parameter model and a numerical example has been given to understand the difference between two models in a better way. An explanation about the proposed methodology as a flow chart also has been shown in appendix.
A Novel Method to Compensate Fiber Nonlinearities by Using NAFO Model
Authors: Singh Kuldeep , Arya Sandeep K.
Published: March 2017

This paper proposes the Nonlinear Adaptive Filter bank–based artificial bee colony Optimizer (NAFO) based on Wiener filter for inverse modeling of nonlinear fiber link. Here a third-order inverse Volterra-based nonlinear equalizer (VNLE) is used to compensate the fiber nonlinearities using MATLAB Simulink. In the novel method the Mean Square Error (MSE) of the optical link is measured and compared with IIR-filter based technique. The MSE is reported to be 10–14value lesser in the novel experimental setup consequently the proposed technique shows enhanced and efficient performance.

Research Article. On memory, dimension, and atmospheric teleconnections

Published: March 2017

Using reanalysed atmospheric data and applying a data-driven multiscale approximation to non-stationary dynamical processes, we undertake a systematic examination of the role of memory and dimensionality in defining the quasi-stationary states of the troposphere over the recent decades. We focus on the role of teleconnections characterised by either zonally-oriented wave trains or meridional dipolar structures. We consider the impact of various strategies for dimension reduction based on principal component analysis, diagonalization and truncation.We include the impact of memory by consideration of Bernoulli, Markovian and non-Markovian processes. We a priori explicitly separate barotropic and baroclinic processes and then implement a comprehensive sensitivity analysis to the number and type of retained modes. Our results show the importance of explicitly mitigating the deleterious impacts of signal degradation through ill-conditioning and under sampling in preference to simple strategies based on thresholds in terms of explained variance. In both hemispheres, the results obtained for the dominant tropospheric modes depend critically on the extent to which the higher order modes are retained, the number of free model parameters to be fitted, and whether memory effects are taken into account. Our study identifies the primary role of the circumglobal teleconnection pattern in both hemispheres for Bernoulli and Markov processes, and the transient nature and zonal structure of the Southern Hemisphere patterns in relation to their Northern Hemisphere counterparts. For both hemispheres, overfitted models yield structures consistent with the major teleconnection modes (NAO, PNA and SAM), which give way to zonally oriented wavetrains when either memory effects are ignored or where the dimension is reduced via diagonalising. Where baroclinic processes are emphasised, circumpolar wavetrains are manifest.
Diatom-based reconstruction of trophic status changes recorded in varved sediments of Lake Żabińskie (northeastern Poland), AD 1888-2010
Authors: Witak Małgorzata , Hernández-Almeida Ivan , Grosjean Martin , Tylmann Wojciech
Published: March 2017

We investigated diatom assemblages in surface sediments of 46 lakes in northern Poland and developed a diatom-based transfer function to infer epilimnetic total phosphorus (TP) concentrations. Multivariate ordination techniques (DCA, CCA) were used to identify major environmental gradients and to evaluate the effect of environmental parameters on the distribution of diatoms in the modern diatom dataset. The transfer function was developed using PLS, WA and WA-PLS models, and applied to a varved sediment core from Lake Żabińskie, AD 1888-2010. Annually-resolved quantitative reconstruction of TP concentrations shows that multidecadal changes in the TP level reflect the local settlement history, land-use changes and development of agriculture and tourism. The period of high trophic levels with maximum values of TP was documented until the late 1920s. In the 1930s-1970s period, TP generally decreased and eutraphentic flora was partly replaced by oligotraphentic and oligo-mesotraphentic diatom taxa. The reconstructed TP concentrations have started to increase from the 1970s. After the 1950s, strong short-term fluctuations of TP values were noted and explained by interactions between meteorological conditions, water column mixing and nutrient cycling in the lake.
First record of Prestauroneis tumida Levkov and accompanying species in Poland
Authors: Rakowska Barbara , Szczepocka Ewelina , Żelazna-Wieczorek Joanna , Olszyński Rafał M.
Published: March 2017

The paper presents morphological and ecological characteristics of Prestauroneis tumida Levkov recorded for the first time in Poland. The diatom Prestauroneis tumida Levkov was found in the microbenthos of the Czarna Staszowska River (left tributary of the Vistula River, south-eastern Poland). This diatom species was present in the upper section of the river (sampling sites: 1 – Drogowle, 2 – Raków) where saprobic state varied from oligosaprobic to beta-mesosaprobic. Dimensions of the valve were as follows: length 30-44 µm, width 8-11 µm and 13-16 striae in 10 µm. Our research updates the morphological diversity data such as measurements of valves in terms of width and the number of striae. The accompanying species of Prestauroneis tumida belonged to the group of good water quality indicators, from oligo- to mesosaprobic ones. Some of the identified species were indicators of alkaline, calcium-rich waters.
Plato,Symposium212a6–7: The Most Immortal of Men, with an Appendix on Phrases of the Type εἴπερ (τις) ἄλλος
Authors: Boter Gerard
Published: March 2017

This article presents two hitherto neglected arguments in favour of the thesis that the philosopher’s immortality described by Diotima in Plato’sSymposiumrefers exclusively to immortality by means of posterity and not to some sort of personal immortality after death. Both arguments are contained in the words 212a6–7 καὶ εἴπερ τῳ ἄλλῳ ἀνθρώπων ἀθανάτῳ καὶ ἐκείνῳ. The first argument concerns the word ἄνθρωπος, the second the phrase εἴπερ τῳ ἄλλῳ καὶ ἐκείνῳ. There is an appendix on phrases of the type εἴπερ τις (ἄλλος).
Pure Theory of the Federal Funds Rate
Authors: Homburg Stefan
Published: March 2017

The effective federal funds rate is determined in a competitive interbank market, while the target federal funds rate represents a policy variable. This paper proposes a theory of the determination of the effective funds rate. According to the main result, the latter is a Lagrange multiplier that vanishes if excess reserves emerge. This is exactly what happened in the United States in September 2008. A final section considers interest on reserves.
Quelle unité à la fin des Douze prophètes? Les jugements divins en Zacharie 14 et Malachie
Authors: Gonzalez Hervé
Published: March 2017

Dieser Artikel befasst sich mit der Einheit des Dodekapropheton, die von vielen Wissenschaftlern angenommen wird, die es für ein einziges Buch halten. Inbesondere konzentriert er sich auf das Ende der Sammlung, vor allem auf die Beziehung zwischen Sach 14 und Maleachi. Obwohl einige neuere Untersuchungen redaktionelle Verbindungen zwischen den beiden Textbereichen identifiziert haben, interessiert man sich kaum die Bedeutung, die entsteht, wenn die Texte in Abfolge gelesen werden. Vor allem in der Diskussion der redaktionellen Hypothesen von O.H. Steck argumentiert der vorliegende Artikel, dass die beiden Texte zwei unterschiedliche Vorstellungen des göttlichen Gerichts enthalten, die kaum miteinander ausgeglichen werden können. Die erstere konzentriert sich auf die Wiederherstellung Jerusalems und deren kosmische Implikationen, die letzere auf die Reinigung der Gemeinschaft und des Kultes. Trotz einiger Verknüpfungen, die das aufeinanderfolgende Lesen der beiden Abschnitte erleichtern, lassen sich eine Reihe konzeptioneller Unterschiede mit Blick auf das Schicksal der Gemeinschaft in Sach 14 und das der fremden Völker in Mal finden. Der Artikel schlägt daher vor, die Einheit des Zwölfprophetenbuches entsprechend einer »aspektiven« Logik zu verstehen: Unterschiedliche Gesichtspunkte werden nebeneinander gestellt, um ein reiches und zusammengesetzes Ensemble zu erreichen. Obwohl ein sequentielles Lesen möglich ist, bleibt dies rein optional. Eine solche Einheit stellt die Vorstellung einer Buchkonzeption in Frage und unterstützt die Idee, es als literarische Sammlung zu verstehen.
Shared Ideas in Job and Deutero-Isaiah
Authors: Kwon JiSeong J.
Published: March 2017

It has been suggested that the books of Job and of Deutero-Isaiah (Isaiah 40–55) have a variety of similarities in their linguistic features and common subject-matter and because of this, it has been argued that there is literary dependence or influence of one book upon the other. Although such an author-oriented approach, by which scholars explain similarities by the theory of literary references, has some value, there is no specific reason to understand those similarities by a sort of direct literary dependence. However, these two books are likely to include the common scribal mindset of the Persian period. Here I put forward shared ideas of God’s universal control and freedom which are distinct from the Mosaic covenant and apocalyptic ideas. With these comparisons between Job/Deutero-Isaiah and other concepts in the Hebrew Bible, I propose the dating of the two books and argue that these cultural ideas about God’s control and freedom reflect the Persian scribal idea on the formation of the two books.

Crystal structures are reported of (E)-2-(4-hydroxybenzylidene)-2,3-dihydro-1H-inden-1-one, 1, (E)-2-(4-dimethylaminobenzylidene)-2,3- dihydro-1H-inden-1-one, 2, (E)-2-(4-cyanobenzylidene)-2,3-dihydro-1H-inden-1-one, 3, and monoclinic-(E)- 2-(3-nitrobenzylidene)-2,3-dihydro-1H-inden-1-one, monoclinic-4, all from data collected at 100 K and (E)-2-(4-hydroxy-3,5-dimethylbenzylidene)-2,3-dihydro-1H-indan-1-one, 6, from data collected at 299 K. An earlier triclinic form of 4 has been reported. Also reported herein are the Hirshfeld suface calculations for these five compounds, as well as that of 2-(4-methoxybenzylidene)-2,3-dihydro-1H-inden-1-one, 5,whose crystal structure has been previously reported. The three rings in each of the compounds, 1–4 and 6, are essentially planar, including the five-membered ring containing a formally hydridized sp3 atom. The molecules exhibit slight deviations from overall planarity as shown by the dihedral angles, >8.15(6)° between the 2,3-dihydro-1H-inden-1-one fragments and the phenyl fragments. The main intermolecular interactions in compounds 1 and are classical O–H···O1(carbonyl) hydrogen bonds. The carbonyl oxygen atom in compounds 1–4 are involved in non-classical C–H···O intermolecular hydrogen bonds. Intermolecular C–H---π interactions are present in 2, 3 and 6, while π···π are present in 2–4 and 6. As noted in the structure determinations of these compounds, different π···π motifs are possible. The Hirshfeld surface calculations, while generally concurring with the intermolecular interactions indicated by PLATON analyses, also reveal significant interactions, which fall below the PLATON radar.

Dendritic GIRK Channels Gate the Integration Window, Plateau Potentials, and Induction of Synaptic Plasticity in Dorsal But Not Ventral CA1 Neurons
Authors: Malik Ruchi , Johnston Daniel
Published: March 2017

Studies comparing neuronal activity at the dorsal and ventral poles of the hippocampus have shown that the scale of spatial information increases and the precision with which space is represented declines from the dorsal to ventral end. These dorsoventral differences in neuronal output and spatial representation could arise due to differences in computations performed by dorsal and ventral CA1 neurons. In this study, we tested this hypothesis by quantifying the differences in dendritic integration and synaptic plasticity between dorsal and ventral CA1 pyramidal neurons of rat hippocampus. Using a combination of somatic and dendritic patch-clamp recordings, we show that the threshold for LTP induction is higher in dorsal CA1 neurons and that a G-protein-coupled inward-rectifying potassium channel mediated regulation of dendritic plateau potentials and dendritic excitability underlies this gating. By contrast, similar regulation of LTP is absent in ventral CA1 neurons. Additionally, we show that generation of plateau potentials and LTP induction in dorsal CA1 neurons depends on the coincident activation of Schaffer collateral and temporoammonic inputs at the distal apical dendrites. The ventral CA1 dendrites, however, can generate plateau potentials in response to temporally dispersed excitatory inputs. Overall, our results highlight the dorsoventral differences in dendritic computation that could account for the dorsoventral differences in spatial representation.

SIGNIFICANCE STATEMENTThe dorsal and ventral parts of the hippocampus encode spatial information at very different scales. Whereas the place-specific firing fields are small and precise at the dorsal end of the hippocampus, neurons at the ventral end have comparatively larger place fields. Here, we show that the dorsal CA1 neurons have a higher threshold for LTP induction and require coincident timing of excitatory synaptic inputs for the generation of dendritic plateau potentials. By contrast, ventral CA1 neurons can integrate temporally dispersed inputs and have a lower threshold for LTP. Together, these dorsoventral differences in the threshold for LTP induction could account for the differences in scale of spatial representation at the dorsal and ventral ends of the hippocampus.
Novel Resampling Improves Statistical Power for Multiple-Trait QTL Mapping
Authors: Cheng Riyan , Doerge R W , Borevitz Justin
Published: March 2017

Multiple-trait analysis typically employs models that associate a quantitative trait locus (QTL) with all of the traits. As a result, statistical power for QTL detection may not be optimal if the QTL contributes to the phenotypic variation in only a small proportion of the traits. Excluding QTL effects that contribute little to the test statistic can improve statistical power. In this article, we show that an optimal power can be achieved when the number of QTL effects is best estimated, and that a stringent criterion for QTL effect selection may improve power when the number of QTL effects is small but can reduce power otherwise. We investigate strategies for excluding trivial QTL effects, and propose a method that improves statistical power when the number of QTL effects is relatively small, and fairly maintains the power when the number of QTL effects is large. The proposed method first uses resampling techniques to determine the number of nontrivial QTL effects, and then selects QTL effects by the backward elimination procedure for significance test. We also propose a method for testing QTL-trait associations that are desired for biological interpretation in applications. We validate our methods using simulations and Arabidopsis thaliana transcript data.
Adapting Genotyping-by-Sequencing for Rice F2 Populations

Published: March 2017

Rapid and cost-effective genotyping of large mapping populations can be achieved by sequencing a reduced representation of the genome of every individual in a given population, and using that information to generate genetic markers. A customized genotyping-by-sequencing (GBS) pipeline was developed to genotype a rice F2 population from a cross of Oryza sativa ssp. japonica cv. Nipponbare and the African wild rice species O. longistaminata. While most GBS pipelines aim to analyze mainly homozygous populations, we attempted to genotype a highly heterozygous F2 population. We show how species- and population-specific improvements of established protocols can drastically increase sample throughput and genotype quality. Using as few as 50,000 reads for some individuals (134,000 reads on average), we were able to generate up to 8154 informative SNP markers in 1081 F2 individuals. Additionally, the effects of enzyme choice, read coverage, and data postprocessing are evaluated. Using GBS-derived markers, we were able to assemble a genetic map of 1536 cM. To demonstrate the usefulness of our GBS pipeline, we determined quantitative trait loci (QTL) for the number of tillers. We were able to map four QTL to chromosomes 1, 3, 4, and 8, and partially confirm their effects using introgression lines. We provide an example of how to successfully use GBS with heterozygous F2 populations. By using the comparatively low-cost MiSeq platform, we show that the GBS method is flexible and cost-effective, even for smaller laboratories.
The effect of quality of written languaging on second language learning
Authors: Suzuki Wataru
Published: March 2017

It has been suggested that oral languaging (e.g., collaborative dialogue, private speech) plays a crucial role in learning a second language (L2). Many studies have shown a positive relation between oral languaging during problem solving tasks and subsequent performance on various post-test measures. The paucity of empirical research on written languaging (e.g., written reflection) prompted this study. The effect of the quality of written languaging by 24 Japanese learners of English was assessed by subsequent text revisions. Both written languaging at the level of noticing only and written languaging at the level of noticing with reasons were associated with accuracy improvement. These findings appear to support Swain’s (2006, 2010) claim that providing learners with the opportunity to language about or reflect on their developing linguistic knowledge in the course of L2 learning mediates L2 learning and development. The pedagogical implications of the study may suggest that L2 teachers should ask their students to reflect, in diaries, journals, and portfolios, on the linguistic problems they have encountered during their classroom activities.
Lead-lag effects between Brent Crude Futures and its respective spot prices
Authors: Angelico Diego Garcia
Published: March 2017

This article aims the analyses of the causality and temporal precedence relationships between the spot and futures prices of Brent oil, those last ones inherent to financial markets. In order to achieve this objective, the main tools used were: Johansen cointegration test; Granger causality/Block Exogeneity Wald test (GCBEW); generalized impulse response function and variance decomposition of forecast errors, those three last ones were estimated based in a Vector Error Correction Model (VEC), adjusted to the analyzed variables. The results indicated that, for the stipulated period, there was a pricing lightweight leadership from the futures contracts to the prices of spot market. However, as a conclusion of the article, the understanding is that this small difference, calculated in several econometric tools, cannot be considered enough to indicate that the Brent oil future market would be distorting its respective spot prices, despite the economic fundamentals of the physical market, such as production, consumption and stockpiling processes. Therefore, management decisions in industries exposed to crude oil prices should be aware of both physical and future markets’ prospections.
Avaliação sistêmica dos impactos sociais da produção da soja para biocombustíveis em Porto Nacional – TO
Authors: Araújo e Silva Thiago de Loiola , Fernandes Ligia Dantas
Published: March 2017

A crise energética atual atinge toda sociedade e aponta para uma mudança no uso e na dependência dos combustíveis fósseis. A atual forma de uso desses combustíveis aponta para a escassez dessa fonte de energia e ao mesmo tempo para o desenvolvimento de outras fontes. Dentre essas está o biodiesel feito a partir do óleo vegetal, onde a soja vem despontando como matéria – prima mais usada na região central do Tocantins. Entretanto, a geração de biodiesel a partir da soja gera impactos socioeconômicos e ambientais. Esses afetam a sociedade direta e indiretamente, sendo as vezes desconhecidos ou ignorados pelos atores envolvidos. Nesse sentido, a presente dissertação objetiva, através do pensamento sistêmico, analisar os impactos sociais gerados a partir da produção de biocombustíveis tendo como matéria - prima a soja no município de Porto Nacional - TO. Para se atingir o objetivo, foi realizado um levantamento de dados bibliográficos, realizadas entrevistas com os atores envolvidos e construída uma estrutura sistêmica. Como resultado, foram diagnosticados os impactos sociais através da relação direta e inversamente proporcional entre as variáveis encontradas durante as entrevistas e a revisão bibliográfica. A aplicação do pensamento sistêmico na identificação dos impactos sociais se mostrou eficiente, permitindo uma visão das relações entre os impactos encontrados e não apenas uma observação superficial.
Gestão de operações em uma economia de baixo carbono: uma revisão da literatura sobre stakeholders, barreiras e motivações
Authors: Ribeiro Daniela Andriani , Jabbour Ana Beatriz Lopes de Sousa
Published: March 2017

O objetivo deste estudo é levantar os stakeholders que agem como barreiras e/ou motivações para a adoção de práticas de gestão de operações de baixo carbono sob a lente da teoria de stakeholder. Os stakeholders exercem forte influência sob as empresas para que as mesmas adotem práticas ambientais devido o contexto da mudança climática e suas consequências no âmbito econômico, ambiental e social. Com isso, este estudo realiza uma revisão da literatura na base de dados Scopus com buscas que relacionam a teoria de stakeholder e práticas de baixo carbono para identificar os stakeholders. Como resultado, Clientes e Governo são os stakeholders mais recorrentes sejam como motivadores ou barreiras à adoção de práticas ambientais. Portanto, é importante compreender os diferentes atributos de cada stakeholder e suas respectivas demandas a fim de traçar estratégias de hierarquização da adoção de eventuais práticas de gestão de operações de baixo carbono, assim como criar mecanismos de colaboração com aqueles stakeholders que motivam a adoção daquelas práticas.

Published: March 2017

Ao longo das últimas décadas a área de gerenciamento de projeto evoluiu e se consolidou. Diante desta evolução, esta pesquisa tem como principal objetivo identificar as principais tendências de pesquisa na área, bem como traçar um panorama das publicações, identificando novos temas, as mudanças de abordagens e a evolução das áreas de conhecimento. Para tanto, com base em um período de mais de 30 anos, foi realizado uma revisão sistemática de literatura e estudo bibliométrico sobre a base de artigos do periódico International Journal of Project Management (IJPM), uma revista constante na base SCOPUS, desde seu primeiro volume até 2015. Entre os resultados, verificou-se que os países em desenvolvimento estão cada vez mais preocupados em realizar estudos sobre o campo da gestão de projetos, com destaque para megaprojetos de infraestrutura e parcerias público-privadas. O tema de risco é central em todos os períodos de análises, no entanto os temas estratégicos como sucesso em projetos e gestão de portfólio estão entre os que mais cresceram. Temas relacionados com o lado soft da gestão de projetos como competências, cultura e gestão de conhecimento tem emergido em períodos recentes. Já quanto ao setor destes artigos foi observado que os projetos de construção e os projetos em tecnologia da informação são os mais estudados em todos o período analisado.

Outrossim, houve um aumento gradativo das notícias sobre o Brasil nas revistas da amostra.
Democracia vs. eficiência: como alcançar equilíbrio em tempo de crise financeira
Authors: Rodrigues Miguel Ângelo Vilela
Published: March 2017

Resumo A administração pública é forçada a encontrar um equilíbrio entre eficiência e democracia na definição da sua agenda e curso de ação. Uma das características da administração pública é que todas as decisões devem refletir valores democráticos, para além de serem eficientes. No entanto, a reforma administrativa, motivada por dificuldades financeiras, tende a destacar a importância do desempenho financeiro, em detrimento dos aspetos democráticos nas políticas de gestão pública. Esta pesquisa visa analisar a relação e tensão entre a eficiência e a democracia à luz da mais recente crise financeira global. O trabalho utiliza uma abordagem quantitativa e recolhe dados de governos locais portugueses para testar o argumento de uma relação linear inversa de desempenho financeiro e procedimentos democráticos. Os resultados confirmam o argumento de uma relação inversa, definida por Waldo (1948). Adicionalmente, os resultados também permitem concluir que a crise financeira evidenciou o efeito negativo dos procedimentos democráticos no desempenho financeiro.
Monetary Policy in the Post Keynesian Theoretical Framework
Authors: TERRA FÁBIO HENRIQUE BITTES , ARESTIS PHILIP
Published: March 2017

ABSTRACT The purpose of this contribution is to develop a Post Keynesian monetary policy model, presenting its goals, tools, and channels. The original contribution this paper develops, following (Keynes’s 1936, 1945) proposals, is the use of debt management as an instrument of monetary policy, along with the interest rate and regulation. Moreover, this paper draws its monetary policy model by broadly and strongly relying on Keynes’s original writings. A monetary policy model erected upon this basis relates itself directly to the Post Keynesian efforts to offer a monetary policy framework substantially different from the Inflation Targeting Regime of the New Macroeconomic Consensus.
Raúl Prebisch e a concepção e evolução do sistema centro-periferia
Authors: COUTO JOAQUIM MIGUEL
Published: March 2017

RESUMO Este artigo descreve a trajetória profissional de Raúl Prebisch e, ao mesmo tempo, analisa sua contribuição teórica no momento em que buscava decifrar a história e os problemas do desenvolvimento econômico da América Latina. De assessor de ministros a direção do Banco Central Argentino, da CEPAL para a UNCTAD, batalhas não lhe faltaram. Enquanto trilhava suas funções públicas, Prebisch foi interpretando teoricamente o mundo em que vivia. Nasceu, assim, o sistema centro-periferia, que incluía as ideias do crescimento para dentro, a deterioração dos termos de intercâmbio e a luta pela industrialização através da substituição de importações.
