Delias hallstromi

description: Delias hallstromi Sanford & Bennett, 1955 (Figs 19-22) Delias hallstromi is a common species in central PNG however the female is rarely encountered. Parsons (1998) illustrates a specimen in the ANIC from Marifunga in the Eastern Highlands. On Mt Hagen, females were frequently seen at locations 1 and 2 feeding on flowering plants. Individual variation is seen in the width of the discocellular bar on the forewing underside and the extent of white markings on the forewing upperside.

description: Event by event EPOS calculations in which the expansion of the system is described by {\it ideal} hydrodynamics reproduce well the measured centrality dependence of $v_2/ε_{part}$, although it has been claimed that only viscous hydrodynamics can reproduce these data. This is due to the core - corona effect which manifests itself in the initial condition of the hydrodynamical expansion. The centrality dependence of $v_2/ε_{part}$ can be understood in the recently advanced core-corona model, a simple parameter free EPOS inspired model to describe the centrality dependence of different observables from SPS to RHIC energies. This model has already been successfully applied to understand the centrality dependence of multiplicities and of the average transverse momentum of identified particles.

description: The purpose of this study is to discuss and examine the determinant of service export in Ethiopia
within global context. A gravity trade mode is engaged by using panel data for 29 main
service trading partners of Ethiopia covering the period 2000-2013, using FGLS econometric
techniques. The  estimation  result  suggests  that  the  service  export  of  the  country  is  highly
dependent on both internet users of Ethiopia and trade partners which could result in facilitate it
when  internet  users  is  further  service  export  by  reduced  transportation  cost  and  expand
customer easily, surprise case since there is existing of infant information technology throughout
the  country.  This  paper  also  assesses  and  confirms  other  determinants  of  the  service  export
sector. The result indicate that GDP per capita of Ethiopia and partners are positively related
to   the   counties   export   while   the  Distance  between  and  common  language  dummy  have
negative impact on the export. Moreover, the analysis suggests that regulatory policies affecting
telecommunications  and  Internet  development  indirectly  affect  service  export,  further
emphasizing  the  importance  of  deregulating  potentially  competitive  services  in  the
telecommunications industry.

description: Production-inventory games were introduced in Guardiola et al. (2007) as a new class of totally balanced combinatorial optimization games. From among all core-allocations, the Owen point was proposed as a specifically appealing solution. In this paper we study some relationships of the class of production-inventory games and other classes of new and known games. In addition, we propose three axiomatic characterizations of the Owen point. We use eight axioms for these characterizations, among those, inessentiality and additivity of players' demands are used for the first time in this paper.

description: Aims. To determine the credentials of nine candidate intermediate polars in order to confirm whether or not they are magnetic cataclysmic variables. Methods. Frequency analysis of RXTE and XMM data was used to search for temporal variations which could be associated with the spin period of the magnetic white dwarf. X-ray spectral analysis was carried out to characterise the emission and absorption properties of each target. Results. The hard X-ray light curve of V2069 Cyg shows a pulse period of 743.2 s, and its spectrum is fit by an absorbed bremsstrahlung model with an iron line, confirming this to be a genuine intermediate polar. The hard X-ray light curve of the previously confirmed intermediate polar IGR J00234+6141 is shown to be consistent with the previous low energy X-ray detection of a 563.5 s pulse period. The likely polar IGR J14536-5522 shows no coherent modulation at the previously identified period of 3.1 hr, but does exhibit a clear signal at periods likely to be harmonically related to it. Whilst our RXTE observations of RX J0153.3+7447, Swift J061223.0+701243.9, V436 Car and DD Cir are largely too faint to give any definitive results, the observation of IGR J16167-4957 and V2487 Oph show some characteristics of intermediate polars and these objects remain good candidates. Conclusions. We confirmed one new hard X-ray selected intermediate polar from our sample, V2069 Cyg.

Year: 2015

description: The main objective of this research is to empirically examine the impact of private and
public physical capital accumulations on economic growth in Ethiopia for the period
ranging   from   1975-2013   by   using   Johansen   maximum  likelihood   co-integration
approach.   The  result  shows  that  real  private  capital  accumulation,  public  capital
accumulation,  human  capital  and  trade  openness  have  positive  and  statistically
significant  impact  while  active  labor  force  has positive but insignificant  impact  in
determining economic growth of Ethiopia in the long run. In addition, in the short run
only  human  capital  at  its  first  difference  is  statistically  significant  in  determining
economic growth in the country while private and public capital stocks have insignificant
impact on real GDP in the short run. This is because their impact may be seen in the long
run  or capital  stock needs a  long  gestation  period to  bring  a  sustainable  increment  in
economic  growth.  Overall,  the  major  policy  implication  of  this  study  is  that,  given  the
long run positive impact of private and public capital stocks on economic growth, it will
be natural to think of supplementary reforms for the development of such sectors.

description: The actin cytoskeleton of adherent tissue cells often condenses into filament bundles contracted by myosin motors, so-called stress fibers, which play a crucial role in the mechanical interaction of cells with their environment. Stress fibers are usually attached to their environment at the endpoints, but possibly also along their whole length. We introduce a theoretical model for such contractile filament bundles which combines passive viscoelasticity with active contractility. The model equations are solved analytically for two different types of boundary conditions. A free boundary corresponds to stress fiber contraction dynamics after laser surgery and results in good agreement with experimental data. Imposing cyclic varying boundary forces allows us to calculate the complex modulus of a single stress fiber.

Constructing Conditional Plans by a Theorem-Prover
Creators: name: Rintanen, J.
Publisher: name: arXiv
Year: 2011
Subjects: subject: Artificial Intelligence (cs.AI)
subject: FOS: Computer and information sciences

description: The research on conditional planning rejects the assumptions that there is no uncertainty or incompleteness of knowledge with respect to the state and changes of the system the plans operate on. Without these assumptions the sequences of operations that achieve the goals depend on the initial state and the outcomes of nondeterministic changes in the system. This setting raises the questions of how to represent the plans and how to perform plan search. The answers are quite different from those in the simpler classical framework. In this paper, we approach conditional planning from a new viewpoint that is motivated by the use of satisfiability algorithms in classical planning. Translating conditional planning to formulae in the propositional logic is not feasible because of inherent computational limitations. Instead, we translate conditional planning to quantified Boolean formulae. We discuss three formalizations of conditional planning as quantified Boolean formulae, and present experimental results obtained with a theorem-prover.

description: Argumentation can contribute significantly to content area learning. Recent research has raised questions about the effects of discussion (deliberation) goals versus persuasion (disputation) goals on reasoning and learning. This is the first study to compare the effects of these writing goals on individual writing to learn. Grade 7 and 8 students learned about buoyancy through argument writing. A 2 x 2 x 2 between-subjects pretest-post-test randomized experiment was used to investigate the effects of two types of argument writing goals (persuasion versus discussion), two distributions of writing sub-goals (segmented versus clustered), and two levels of writing achievement (low versus high) on bias/balance in reasoning, cognitive load, and learning. Results showed that segmented sub-goals were rated less difficult than clustered sub-goals. In a three-way interaction, for high-achieving writers, sub-goal segmentation reduced cognitive load in discussion writing, but increased it in persuasive writing. Argument goal type and sub-goal distribution affected bias/balance in claims and inferences. These results suggest that the effects of argument goal type are moderated by sub-goal distribution and previous writing achievement. L’argumentation peut contribuer de façon significative à l’apprentissage dans les cours à contenu. Des recherches récentes ont soulevé des questions quant aux effets des objectifs de la discussion (délibération) par rapport aux objectifs de la persuasion (contestation) sur le raisonnement et l’apprentissage. Cette étude est la première à comparer les effets de ces objectifs de rédaction sur des élèves apprenant à écrire. Des élèves en 7e et 8e année ont appris au sujet de la flottabilité en écrivant des textes argumentatifs. Une expérience 2 x 2 x 2 inter-sujet avant-après avec randomisation a porté sur les effets de deux types d’objectifs de textes argumentatifs (persuasion ou discussion), deux distributions de sous-objectifs de rédaction (segmentation ou regroupement) et deux niveaux de rendement en écriture (bas ou élevé) sur l’équilibre quant au raisonnement, la charge cognitive et l’apprentissage. Les résultats ont indiqué que les sous-objectifs segmentés étaient perçus comme étant moins difficiles que les sous-objectifs regroupés. Dans une interaction à trois, la segmentation des sous-objectifs a réduit la charge cognitive dans les rédactions explicatives, mais l’a augmentée dans les textes argumentatifs chez les écrivains de haute qualité. Le type d’objectifs et la distribution des sous-objectifs ont affecté l’équilibre dans les affirmations et les inférences. Ces résultats portent à croire que les effets du type d’objectifs sont modérés par la distribution des sous-objectifs et par le rendement antérieur en rédaction.

Year: 2015

description: The main objective of this study is to empirically examine the major determinants of tax reve
nue in Ethiopia for the period ranging from 1975-2013, using Johansen maximum likelihood
co-integration approach. The result revealed that level of real GDP per capita income, infla
tion, foreign aid and industrial share of GDP are significant variables that determine tax rev
enue in the long run. Moreover, in the long run real GDP per capita income, foreign aid and
industrial value added share of GDP positively and significantly affect tax revenue as per
centage of GDP. However, inflation exerted a negative and significant influence. Whereas, in
the short run only the level of real GDP per capita income, industrial value added share of
GDP and inflation rate are statistically significant in determining tax revenue percentage of
GDP. Real GDP per  capita income and inflation have negative  effect,  whereas  industrial
Value added share of GDP has positive effect in the short run. The sign of real gross domestic
product per capita income is contrary to the priori expectation. Moreover, the coefficients of
the lagged error correction term (ECM (-1)) is significant and negative as expected, which
imply the existence of economic or government forces that restore the long run equilibrium
from short run shocks. Finally, the study recommends measures such as a boost in per capita
income growth, structural transformations, introduction of new tax bases and efficient utili
zation of foreign aid inflow have to be considered by the concerned bodies so as to bring
efficient tax administration and enhance revenue growth. Moreover, the government shall give
a due recognition to the development of the industrial sector.

FARMERS WILLINGNESS TO PAY AND CHOICE OF SMALLHOLDER  WATER LIFTING TECHNOLOGIES: EVIDENCE FROM ADAMI TULU,  LEMO AND DANGELA WEREDAS, ETHIOPIA.
Creators: name: MENEYAHEL ZEGEYE TESFAYE
Publisher: name: National Academic Digital Repository of Ethiopia

description: This paper analyzes the farmers’ willingness to pay (WTP)  and demand  for the  smallholder
water  lifting  technologies  (SWLTs).  The  study  employed  Contingent  valuation  method
(CVM),  and  212  farmers’  were  selected  based  on  multi-stage  sampling  technique  from
three  weredas,  Adami  Tulu,  Lemo  and  Dangela.  The  selected  sample  households  were
asked a contingent valuation question using a double bounded elicitation with open ended
follow up question. To examine the determinants of WTP  and to compute the mean WTP
for the  SWLTs, probit and bivariate probit model were used. Using multinomial logit model
determinants of demand  for the SWLTs namely, motor pump, rope and washer and pulley
were also examined.  The probit model result shows that household  size, household income,
initial  bid  values,  access  to  credit,  access  to  market,  off-farm  activity  and  land  size
significantly  affect  the  probability  of  the  households’  WTP  for  the  SWLTs.  From  the
bivariate  probit  model,  the  computed  mean  WTP  for  the  SWLTs  using  double  bounded
elicitations (DBE) are 18,575, 4,497.7 and 1,709 birr for motor pump, rope and washer
and  pulley  respectively.  The  computed  open  ended  elicitation  mean  WTP  values  are
15,226.70,  3,452.31and  1,218.33  birr  for  motor  pump,  rope  and  washer  and  pulley
respectively. Likewise, the total WTP for motor pump, rope and washer and pulley from the
DBE method is 14,265,600, 4,889,000 and 948,495 birr respectively. The total WTP for
motor  pump,  rope  and  washer  and  pulley  from  open  ended  elicitation  is  11,694,083,
3,752,661 and 676,173.15 birr respectively.  The multinomial logit model result  shows that,
sex of the household head, credit access, household income, off-farm activity, access to
market, quality of soil, ownership mode, agro-ecological zone and land size are found to
be  significant in affecting the probability of the households’  demand for the  SWLTs. The
main findings of this paper is that farmers’ are willing to pay for the SWLTs. But, the level
of WTP and choice of technology is contingent upon and different from location to location.
The DBE  resultk2  shows that market price of rope and washer and motor pump lies between
farmers’ upper and lower range of WTP bound  but farmers’ are more willing to pay for
pulley higher than what the existing market reveals.  Also, the mean values obtained from
the open ended elicitation is lower than  the values from the double bounded elicitation.
Thus, policy makers should be careful on the selection of the elicitation technique to elicit
the farmers’ WTP. Moreover, the comparative analysis between  male and female headed
household shows that females are less willing to pay for the SWLTs.

description: In this paper a new technique for modeling non-linear force-free fields directly from line of sight magnetogram observations is presented. The technique uses sequences of magnetograms directly as lower boundary conditions to drive the evolution of coronal magnetic fields between successive force-free equilibria over long periods of time. It is illustrated by applying it to MDI observations of a decaying active region, NOAA AR 8005. The active region is modeled during a 4 day period around its central meridian passage. Over this time, the dispersal of the active region is dominated by random motions due to small scale convective cells. Through studying the build up of magnetic energy in the model, it is found that such small scale motions may inject anywhere from $2.5-3 \times 10^{25}$ erg s$^{-1}$ of free magnetic energy into the coronal field. Most of this energy is stored within the center of the active region in the low corona, below 30 Mm. After 4 days the build-up of free energy is 10% that of the corresponding potential field. This energy buildup, is sufficient to explain the radiative losses at coronal temperatures within the active region. Small scale convective motions therefore play an integral part in the energy balance of the corona. This new technique has wide ranging applications with the new high resolution, high cadence observations from the SDO:HMI and SDO:AIA instruments.

description: Half of all primary energy input in North America is lost as unused heat. Turning this waste heat into usable energy through waste-heat-to-power (WHP) technologies could help to economically meet climate objectives. Compressor stations on natural gas transmission lines have been identified as a significant potential source of WHP, which would generate electricity with negligible incremental carbon emissions. Installations usually occur as retrofits, and are not dependent on transmission expansion or stock turnover. In Canada, ten such installations were made between 2007 and 2013, but represent a penetration of only 6% of compressor stations. This study conducts an integrated assessment of technical, economic, institutional, regulatory, and policy factors affecting WHP development to examine drivers and barriers, along with appropriate policy levers. Given the quantified installed gas transmission turbine capacity of 4.6 GW, there is over 1.1 GW of WHP technical potential on Canadian compressor stations. Combined with turbine capacity factors estimated from pipeline throughput and capacity data and costs from past installations, 0.3 GW is estimated to be economically viable. The majority of remaining viable WHP capacity is in Alberta. These are competitive with new natural gas combined cycle plants with a $50 per tonne carbon price. Investment is sensitive to the electricity purchase price, turbine capacity factor, cost of capital, and electrical grid interconnection costs. Generation is expected to be baseload or correlated to seasonal electricity demand fluctuations. Three primary barriers to implementation were discovered. WHP is not consistently recognized as a clean electricity source in all jurisdictions, including Alberta. Regulations for steam systems that require continuous on-site monitoring by appropriately certified Power Engineers add significant operating expenses. While gas compressor operation shifted to remote monitoring of automated systems following technological advances in past decades, on-site monitoring thresholds for thermal power generation have not changed since 1975 and should be reassessed to ensure benefits warrant the costs. Lastly, interpretations of cost-of-service regulations have funneled significant benefits back to gas shippers, in addition to transmission companies and WHP developers. This split incentive has reduced the attractiveness of WHP development to decision makers.

description: The study was carried out at Damot Gale Woreda of Wolayta Zone in Southern Nation
Nationalities  Regional  State  with  the  main  objectives  to  describe  correlates  or
determinants of rural poverty in the study area. In order to attain this objective the study
made use of cross-sectional household survey data collected from 235 sample households
.The data collected were analyzed and discussed applying FGT measure of poverty i.e.
poverty head count index, poverty gap and severity. Using cost of basic needs approach;
the study found that total poverty line (food and non food poverty line) of the study area
was about 3612.151birr per year per adult equivalent consumption.  Using this poverty
line as bench mark the study indicated that 56.17 percent of the households were poor.
The result of the logistic regression model revealed that out of 18 variables included in
the model, 13 explanatory  variables were found  to  be  significant  at 1%,  5% and 10%
level. Accordingly, family size, household head sex, household age, dependency ratio and
marital status were found to have positive association with poverty of the household and
statistically  significant.  Mean while  Age square, cultivated  land size, oxen,  access  to
credit, off farm activity, household health, remittance, and market access were found out
to have strong negative association with the households poverty status and statistically
significant up to less than 10% level of significance.

description: Stacked generalization is a general method of using a high-level model to combine lower-level models to achieve greater predictive accuracy. In this paper we address two crucial issues which have been considered to be a `black art' in classification tasks ever since the introduction of stacked generalization in 1992 by Wolpert: the type of generalizer that is suitable to derive the higher-level model, and the kind of attributes that should be used as its input. We find that best results are obtained when the higher-level model combines the confidence (and not just the predictions) of the lower-level ones. We demonstrate the effectiveness of stacked generalization for combining three different types of learning algorithms for classification tasks. We also compare the performance of stacked generalization with majority vote and published results of arcing and bagging.
Relationships between Language Teachers’ Time-management Skills, Creativity, and Burnout: A Mediation Analysis
Creators: name: Mahmoodi-Shahrebabaki, Masoud
Publisher: name: Alberta Journal of Educational Research
Year: 2015

description: The present study aimed to investigate the effects of language teachers` time management and creativity skills on their burnout levels. The sample consisted of 213 Iranian language teachers. The Maslach Burnout Inventory (MBI), Creative Behavior Inventory (CBI) and Time Management Skills Questionnaire (TMSQ) were employed for data collection. By taking a Structural Equation Modeling approach, the study proposed a model that explored the direct effects of teacher creativity on burnout level of language teachers. Additionally, the study investigated the mediating role of time management skills on the correlations between teacher creativity and burnout levels. The results revealed that the total effects of creativity on all aspects of burnout dimensions were significant; however, after the intervention of time management as a variable, the effect of depersonalization proved insignificant; and, although still significant, for the other two subscales of burnout (emotional exhaustion and depersonalization), the effect markedly decreased. Therefore, the mediation role of time management was rejected. La présente étude porte sur les effets de la gestion du temps et la créativité des enseignants sur leurs niveaux d’épuisement. L’échantillon des participants consistait en 213 enseignants de langue iraniens. L’inventaire d’épuisement mis au point par Maslach, l’inventaire du comportement créatif et un questionnaire portant sur les compétences de gestion du temps, ont servi dans la collecte des données. Adoptant l’approche de la modélisation par équation structurelle, l’étude a proposé un modèle qui a exploré les effets directs de la créativité des enseignants de langue sur leur niveau d’épuisement. De plus, l’étude s’est penchée sur le rôle de médiateur que pourraient jouer les compétences en gestion du temps sur les corrélations entre la créativité des enseignants et les niveaux d’épuisement. Les résultats indiquent que dans leur ensemble, les effets de la créativité sur tous les aspects de l’épuisement sont significatifs; toutefois, quand on introduisait la gestion du temps comme variable, l’effet de la dépersonnalisation n’était pas significatif. Quant aux deux autres sous-échelles de l’épuisement (épuisement émotif et dépersonnalisation), l’effet a nettement diminué, tout en restant significatif. Le rôle de médiateur de la gestion du temps a donc été rejeté.

description: Observations of clusters of galaxies show ubiquitous presence of X-ray cavities, presumably blown by the AGN jets. We consider magnetic field structures of these cavities. Stability requires that they contain both toroidal and poloidal magnetic fields, while realistic configurations should have vanishing magnetic field on the boundary. For axisymmetric configurations embedded in unmagnetized plasma, the continuity of poloidal and toroidal magnetic field components on the surface of the bubble then requires solving the elliptical Grad-Shafranov equation with both Dirichlet and Neumann boundary conditions. This leads to a double eigenvalue problem, relating the pressure gradients and the toroidal magnetic field to the radius of the bubble. We have found fully analytical stable solutions. This result is confirmed by numerical simulation. We present synthetic X-ray images and synchrotron emission profiles and evaluate the rotation measure for radiation traversing the bubble.

description: This work aims to characterize ultra high dose rate pulses (UHDpulse) electron beams using the hybrid semiconductor pixel detector. The Timepix3 (TPX3) ASIC chip was used to measure the composition, spatial, time, and spectral characteristics of the secondary radiation fields from pulsed 15 to 23 MeV electron beams. The challenge is to develop a single compact detector that could extract spectrometric and dosimetric information on such high flux short pulsed fields. For secondary beam measurements, PMMA plates of 1 and 8 cm thickness were placed in front of the electron beam, with a pulse duration of 3.5 microseconds. Timepix3 detectors with silicon sensors of 100 and 500 micrometers thickness were placed on a shifting stage allowing for data acquisition at various lateral positions to the beam axis. The use of the detector in FLEXI configuration enables suitable measurements in situ and minimal self shielding. Preliminary results highlight both the technique and the detector's ability to measure individual UHDpulses of electron beams delivered in short pulses. In addition, the use of the two signal chains per pixel enables the estimation of particle flux and the scattered dose rates (DRs) at various distances from the beam core, in mixed radiation fields.

description: This phenomenological study (Creswell, 2003, 2007; van Manen, 1997) explores student and teacher perceptions of first language use in French immersion mathematics classrooms at a large, urban high school in Canada. During individual interviews, participants discussed their perceptions and experiences of French immersion mathematics, language use, and, in particular, first language use. Interview data are analysed through a sociocultural theory lens (e.g., Lantolf, 2000; Swain & Lapkin, 2000), drawing on key notions such as language interdependence and the use of language as a cognitive tool. While first language use in second language classrooms remains controversial, this article contributes to an open discussion on the potential role students’ first language can play in determining effective language and content learning. Cette étude phénoménologique (Creswell, 2003, 2007; van Manen, 1997) porte sur les perceptions des élèves et des enseignants sur l’emploi de la langue première pendant les cours de mathématiques dans un contexte d’immersion française d’une grande école secondaire en milieu urbain au Canada. Pendant les entrevues individuelles, les participants ont discuté de leurs perceptions et leurs expériences relatives aux cours de mathématiques en immersion et à l’emploi de langue, notamment la langue première. Les données d’entrevues ont été analysées dans l’optique de la théorie socioculturelle (p.ex., Lantolf, 2000; Swain & Lapkin, 2000), puisant dans des notions clés telles l’interdépendance des langues et l’emploi de langue comme outil cognitif. Alors que l’emploi de la première langue dans les classes d’immersion est controversé, cet article contribue à une discussion ouverte sur le rôle potentiel que peut jouer la langue première des élèves dans la détermination de l’apprentissage efficace de la langue et du contenu.

description: The Berry phase and the group-velocity-based traversal time have been calculated for an asymmetric non-contacted or contacted graphene structure, and significant differences have been observed compared to semiconductor heterostructures. These differences are related to the specific, Dirac-like evolution law of charge carriers in graphene, which introduces a new type of asymmetry. When contacted with electrodes, the symmetry of the Dirac equation is broken by the Schrodinger-type electrons in contacts, so that the Berry phase and traversal time behavior in contacted and non-contacted graphene differ significantly.

description: We study the dynamics of carriers in graphene subjected to an inhomogeneous magnetic field. For a magnetic field with an hyperbolic profile the corresponding Dirac equation can be analyzed within the formalism of supersymmetric quantum mechanics, and leads to an exactly solvable model. We study in detail the bound spectra. For a narrow barrier the spectra is characterized by a few bands, except for the zero energy level that remains degenerated. As, the width of the barrier increases we can track the bands evolution into the degenerated Landau levels. In the scattering regime a simple analytical formula is obtained for the transmission coefficient, this result allow us to identify the resonant conditions at which the barrier becomes transparent.
