The Effect of a Short Planning Horizon on Intertemporal Consumption Choices

Previous experimental results (Ballinger et al. (2003) and Carbone and Hey (2004)) have found that many agents fail to correctly take into account the length of the planning horizon also finding some support (See Carbone (2006)) for descriptive models, such as the Rolling Model. This paper presents an experimental analysis on the effect of a short planning horizon on intertemporal consumption choices. The purpose of the study is to test whether very short horizons are more easily perceived by agents, allowing them to plan optimally. This experiment tests a somewhat implicit assumption of the Rolling Model, or of similar descriptive approaches, namely that people might be able to use the optimal strategy if they are faced with shorter planning horizons. Moreover, this hypothesis is tested in the cases of decision making under certainty, risk and uncertainty, in order to analyze how these environments may affect the perception of the length of the planning horizon. Results suggest that planning periods have a significant effect on deviations from unconditional optimum in all sequences and all treatments. This finding has been interpreted as evidence of participants not using the optimal strategy. When conditional deviations are considered, results are confirmed only in the case of decision making under uncertainty. This second finding has been interpreted as suggesting that uncertainty on income seems to prevent participants from improving their decision making.
Timed Context-Free Temporal Logics

The paper is focused on temporal logics for the description of the behaviour of real-time pushdown reactive systems. The paper is motivated to bridge tractable logics specialized for expressing separately dense-time real-time properties and context-free properties by ensuring decidability and tractability in the combined setting. To this end we introduce two real-time linear temporal logics for specifying quantitative timing context-free requirements in a pointwise semantics setting: Event-Clock Nested Temporal Logic (EC_NTL) and Nested Metric Temporal Logic (NMTL). The logic EC_NTL is an extension of both the logic CaRet (a context-free extension of standard LTL) and Event-Clock Temporal Logic (a tractable real-time logical framework related to the class of Event-Clock automata). We prove that satisfiability of EC_NTL and visibly model-checking of Visibly Pushdown Timed Automata (VPTA) against EC_NTL are decidable and EXPTIME-complete. The other proposed logic NMTL is a context-free extension of standard Metric Temporal Logic (MTL). It is well known that satisfiability of future MTL is undecidable when interpreted over infinite timed words but decidable over finite timed words. On the other hand, we show that by augmenting future MTL with future context-free temporal operators, the satisfiability problem turns out to be undecidable also for finite timed words. On the positive side, we devise a meaningful and decidable fragment of the logic NMTL which is expressively equivalent to EC_NTL and for which satisfiability and visibly model-checking of VPTA are EXPTIME-complete.
Dry matter portioning, yield attributes and yield of Bt cotton as influenced by different fertigation levels with conventional and water soluble fertilizers

A field experiment was undertaken to study the effect of different fertigation levels with conventional and water soluble fertilizers (WSF) on dry matter (DM) portioning, yield attributes and yield of Bt cotton at ARS, Dharwad, Karnataka during the kharif season of 2016-17. The results indicated that paired row (PR) sowing with fertigation of 100 per cent RDF (150:75:75 kg ha) through conventional fertilizers (CF) applied in six equal splits (T9) recorded significantly higher DM portioning to different parts and total DM production per plant at different growth stages as compared to other treatments. Regarding to yield and yield contributing parameters, PR sowing with fertigation of 100 per cent RDF through CF applied in six equal splits (T9) recorded significantly higher number of bolls plant (54.40), seed cotton yield plant (275.20 g) and seed cotton yield ha (40 q ha) than other treatments, but was on par with PR sowing with fertigation of 30 per cent RDF (45: 22.5: 22.5 kg ha) through WSF and 25 per cent RDF through CF applied in six equal splits i.e T5 (50.07, 251.43 g and 38.94 q ha, respectively) and PR sowing with fertigation of 25 per cent RDF (37.5: 19: 19 kg ha) through WSF and 25 per cent RDF through CF applied in six equal splits i.e T6 (48.13, 243.27 g and 37.83 q ha, respectively). Significantly lower bolls plant (39.20), seed cotton yield plant (196.40 g) and seed cotton yield ha (26.38 q ha) was recorded in PR sowing with fertigation of 15 per cent RDF (22.5: 11: 11 kg ha) through WSF applied in six equal splits (T4). Number of sympodia plant and mean boll weight did not differ significantly among different treatments, but increased fertigation levels resulted increased number of sympodia plant and mean boll weight.
Effects of fertilizer phosphorus and poultry droppings treatments on growth and nutrient components of pepper (Capsicum annuum L)

The effect of five phosphrous levels (0, 25, 50, 75, 100 and 125 kg/ha) and five poultry dropping (0, 100, 200, 300, 400 and 500 kg/ha) levels on the growth, growth yield, yield components, nutrients concentration and food values of pepper (Capsicum annuum L) were observed from 2002 to 2003 raining seasons. Phosphrous levels significantly increased pepper plant height, number of leaves per plant, number of branches per plant and leaf area up to 125 kg (p/ha) level. The phosphorus application also significantly increased early flowering, maturity and yield (ton/ha) of the treated plants. Application of organic waste, poultry dropping increased the growth yield and yield components of pepper significantly more than the fertilizer phosphrous. Since poultry dropping is cheap to obtain and enhances the pepper plant performance, it is recommended for use. C. annuun was found to contain both the major and minor nutrient elements which can supply the body with necessary ingredients for growth. Key words: Poultry droppings; caspicum species, nutrient contents, interaction absorption.
What can the observation of nonzero curvature tell us

The eternally inflating multiverse provides a consistent framework to understand coincidences and fine-tuning in the universe. As such, it provides the possibility of finding another coincidence: if the amount of slow-roll inflation was only slightly more than the anthropic threshold, then spatial curvature might be measurable. We study this issue in detail, particularly focusing on the question: "If future observations reveal nonzero curvature, what can we conclude? " We find that whether an observable signal arises or not depends crucially on three issues: the cosmic history just before the observable inflation, the measure adopted to define probabilities, and the nature of the correlation between the tunneling and slow-roll parts of the potential. We find that if future measurements find positive curvature at \Omega_k 10^-4, then we can conclude (1) diffusive (new or chaotic) eternal inflation did not occur in our immediate past; (2) our universe was born by a bubble nucleation; (3) the probability measure does not reward volume increase; and (4) the origin of the observed slow-roll inflation is an accidental feature of the potential, not due to a theoretical mechanism. Discovery of \Omega_k > 10^-4 would also give us nontrivial information about the correlation between tunneling and slow-roll; e.g. a strong correlation favoring large N would be excluded in certain measures. We also ask whether the current constraint on \Omega_k is consistent with multiverse expectations, finding that the answer is yes, except for certain cases. In the course of this work we were led to consider vacuum decay branching ratios, and found that it is more likely than one might guess that the decays are dominated by a single channel.
Observational Signatures of Cloud–Cloud Collision in the Extended Star-forming Region S235

We present a multi-wavelength data analysis of the extended star-forming region S235 (hereafter E-S235), where two molecular clouds are present. In E-S235, using the 12CO (1–0) and 13CO (1–0) line data, a molecular cloud linked with the site “S235main” is traced in a velocity range [−24, −18] km s−1, while the other one containing the sites S235A, S235B, and S235C (hereafter “S235ABC”) is depicted in a velocity range [−18, −13] km s−1. In the velocity space, these two clouds are separated by ∼4 km s−1, and are interconnected by a lower-intensity intermediate velocity emission, tracing a broad bridge feature. In the velocity channel maps, a possible complementary molecular pair at [−21, −20] km s−1 and [−16, −15] km s−1 is also evident. The sites, “S235ABC,” east 1, and south–west, are spatially seen in the interface of two clouds. Together, these observed features are consistent with the predictions of numerical models of the cloud–cloud collision (CCC) process, favoring the onset of the CCC in E-S235 about 0.5 Myr ago. Deep UKIDSS near-infrared photometric analysis of point-like sources reveals significant clustering of young stellar populations toward the sites located at the junction, and the “S235main. ” The sites “S235ABC” harbor young compact H ii regions with dynamical ages of ∼0.06–0.22 Myr, and these sites (including south–west and east 1) also contain dust clumps (having Mclump ∼ 40 to 635 M ⊙ ). Our observational findings suggest that the star formation activities (including massive stars) appear to be influenced by the CCC mechanism at the junction.
Locating Microseismic Events using a Single Vertical Well Data

Recently, hydraulic fracturing is used in various fields and microseismic monitoring is one of the best methods for judging where hydraulic fractures exist and how they are developing. When locating microseismic events using single vertical well data, distances from the vertical array and depths from the surface are generally decided using time differences between compressional (P) wave and shear (S) wave arrivals and azimuths are calculated using P wave hodogram analysis. However, in field data, it is sometimes hard to acquire P wave data which has smaller amplitude than S wave because microseismic data often have very low signal to noise (S/N) ratio. To overcome this problem, in this study, we developed a grid search algorithm which can find event location using all combinations of arrival times recorded at receivers. In addition, we introduced and analyzed the method which calculates azimuths using S wave. The tests of synthetic data show the inversion method using all combinations of arrival times and receivers can locate events without considering the origin time even using only single phase. In addition, the method can locate events with higher accuracy and has lower sensitivity on first arrival picking errors than conventional method. The method which calculates azimuths using S wave can provide reliable results when the dip between event and receiver is relatively small. However, this method shows the limitation when dip is greater than about in our model test.
Comparative Study On The Productivity And Profitability Of Commercial Broiler, Cockerel Of A Layer Strain And Cross-Bred (Rir × Fayoumi) Chicks

An experiment was conducted to compare the productivity and profitability of commercial broiler, cockerel and cross-bred (F1 RIR ? × Fayoumi ? ) chicks up to target body weights of 850, 1000 and 1250g. Two hundred sixteen birds of 3 genotypes each of 72 birds having 18 chicks in each replication were considered. Commercial broiler starter diet was fed to experimental birds ad libitum . Similar care and management were provided to birds of all treatment groups. Commercial broilers attained the target weights of 850, 1000 and 1250g at the age of 21, 24 and 28 days respectively whereas cockerels attained weights close to those targets at 56, 63 and 74 days respectively and in the case of cross-breds, the days were 63, 77 and 90 for those target weights respectively. Feed conversion ratio (FCR) was best in broilers, followed by cockerels and cross-bred chicks respectively. The highest mortality (8.3%) was found in cross-bred group when reared up to target weight of 1250g. The mortality of broiler was 1.4% and no bird was died in cockerel group. Broiler was most profitable (21.11 Tk/kg live bird) at the target weight of 1250g whereas profit from cockerel varied little (21.78, 21.07 and 21.63 Tk/kg live bird against the target weights of 850, 1000 and 1250g respectively) amoung target weights. Therefore, appropriate weight to market these birds was at 850g to minimize the risk of diseases and other management works. Marketing of cross-bred chicks was most profitable (8.43 Tk/kg live bird) at 850g target weight and loss was incurred when rearing was continued up to 1250g. On the basis of results of productivity, it was concluded that commercial broiler, cockerel and cross-bred chicks could be reared upto 28, 56 and 63 days respectively to reach target weights close to 1250, 850 and 850g respectively to obtain maximum profit.

An analysis of the relative importance of biotic and abiotic factors to the niche of the cockroach genus Arenivaga (Rehn) (Blattodea: Corydiidae) 1

Arenivaga occur across the American Southwest and Mexico, as well as in the scrub and high pine communities of Florida. This study analyzes the relative contribution of 22 abiotic and one biotic variable to the niche of the genus Arenivaga. This analysis revealed that more than 95% of their ecological niche is described by eight variables: soil, isothermality, minimum temperature of the coldest month, mean temperature of the driest quarter, annual precipitation, precipitation of the driest month, precipitation of the wettest quarter and ground cover. These eight variables with respect to their relative contributions to the niche of the genus as a whole as well as the individual niches of 27 species in the genus were then examined. This revealed the similarity of niche composition of most of the species, as well as how varied the niches were of several species. A species dendrogram built from similarity of contribution of the eight variables to niche composition was compared to a phylogeny of the genus, but few similarities in topology were found. This analysis revealed that soil is the most important contributor t o these species' niches, followed by precipitation of the driest month, and finally, precipitation of the wettest quarter. It also confirmed that the majority of Arenivaga species have niches comprised of similar, but not identical, proportions of as few as four, and as many as eight ecological variables. Currently there is no evidence to support niche conservatism between closely related species, indicating that adapting to new and variable niches is one of the drivers of speciation in this genus.
NONLINEAR INSTABILITY OF COUPLED CNTS CONVEYING VISCOUS FLUID

In the present study, nonlinear vibration of coupled carbon nanotubes (CNTs) in presence of surface effect is investigated based on nonlocal Euler-Bernoulli beam (EBB) theory. CNTs are embedded in a visco-elastic medium and placed in the uniform longitudinal magnetic field. Using von Karman geometric nonlinearity and Hamilton’s principle, the nonlinear higher order governing equations are derived. The differential quadrature (DQ) method is applied to obtain the nonlocal frequency of coupled visco-CNTs system. The effects of various parameters such as the longitudinal magnetic field, visco-Pasternak foundation, Knudsen number, surface effect, aspect ratio and velocity of conveying viscous are specified. It is shown that the longitudinal magnetic field is responsible for an up shift in the frequency and an improvement of the instability of coupled system. Results also reveal that the surface effect and internal conveying fluid plays an important role in the instability of nano coupled system. Also, it is found that trend of figures have good agreement with previous researches. It is hoped that the nonlinear results of this work could be used in design and manufacturing of nano/micro mechanical system in advanced nanomechanics applications where in this study the magnetic field is a controller parameter.
Quantitative assessment of the morphogenetic efficiency in strawberry Fragaria × ananassa Duch

Abstract A quantitative assessment of the morphogenetic capability of strawberry was performed. In the experiment, three genotypes of strawberry Fragaria × ananassa Duch. were tested, including two cultivars: ‘Plena’ and ‘Kent’, and one breeding clone no. „394‟. Morphogenetic efficiency was expressed by the mean number of microplants produced by the explant of progeny combinations F1 in two subsequent subcultures. Progeny F1 was obtained after crossings, which were carried out according to Griffing's method 3, with the use of the parental genotypes given above. Quantitative parameters: combining ability and the effect of reciprocal crosses estimated in the progeny F1 allowed to assess the genetic control of the analysed feature. The high positive effect of reciprocal crosses showed that in „Plena‟ the morphogenetic capability is genetically controlled mainly by nuclear genes. On the other hand, aspects of extranuclear inheritance of the analysed trait were observed in ‘Kent’, which proved a weak explant ability of the progeny combination F1 to produce microplants. This resulted in the high negative effect of reciprocal crosses for that cultivar
A Qualitative Study on Learning and Teaching with Learning Paths in a Learning Management System.

This article presents the findings of a qualitative study (carried out between 2011 and 2013) about the adoption and implementation of learning paths within a Learning Management System (LMS). Sixteen secondary school biology teachers of the GO! Network in Flanders (an urbanized region in Belgium) were involved in the study and questioned via semi-structured interviews. Two research questions are addressed: (1) what are the perceived conditions at school and at teacher level affecting the use of learning paths? (2) how are these conditions related to the expected outcomes? Research results show teachers are satisfied with learning paths as an educational tool, but reflect mixed feelings as to the impact on student learning outcomes. Clear barriers are identified at the school and teacher level, thwarting the implementation of learning paths in secondary education. The availability of a reliable and accessible ICT infrastructure, the quality of technical and pedagogical support, teacher professional development and the mastery of teacher Information and Communication Technology competencies, among others, were found to be essential. Questo articolo presenta i risultati di uno studio qualitativo sull'adozione e l'attuazione di percorsi di apprendimento all'interno del Learning Management System (LMS). Sedici insegnanti della scuola secondaria sono stati coinvolti nello studio e interrogati tramite interviste semi-strutturate. Si sono prese in considerazione due domande di ricerca: (1) quali sono le condizioni percepite nella scuola e fra gli insegnanti capaci di influenzare l'uso di percorsi di apprendimento (learning paths)? (2) come sono legate ai risultati attesi queste condizioni? I risultati della ricerca mostrano che gli insegnanti sono soddisfatti dei percorsi di apprendimento (learning paths) come strumento educativo, ma mostrano sentimenti contrastanti per quanto riguarda l'impatto sui risultati di apprendimento degli studenti. Si identificano chiari ostacoli a livello di scuola e di insegnanti, vanificando l'utilizzo dei learning paths nell’ istruzione secondaria. Si sono rivelati essenziali, fra l’altro, la disponibilita di infrastruttura ICT affidabili e accessibili, la qualita del supporto tecnico e pedagogico, lo sviluppo professionale degli insegnanti e la padronanza delle tecnologie dell'informazione e della comunicazione.
The Evaluation of Soft Power Investment Effect on Shanghai Port Competitiveness Using DEA method

With the economy development, the competition among ports becomes increasingly intense. In order to improve the overall competitiveness of Shanghai, this paper proposes a systematic evaluation model for the competitiveness of Shanghai Port with 25 input indicators (e.g. port infrastructure and port soft power) and 6 output indicators (e.g. Port service level and port development potential). The proposed evaluation model reduces the dimensions of the indices by Factor Analysis, and uses the data envelopment analysis (DEA) to validate the analysis of Shanghai Port from 2008 to 2013. By implementing the cross-evaluation mechanism after analyzing the factor deviation, this paper is capable to recognize the pros and cons of each decision-making unit (DMU), and point out the improvement direction for each DMU, so as to enhance the competitiveness of Shanghai Port.
A Hybrid Particle Swarm Optimization and Support Vector Regression Model for Financial Time Series Forecasting

In this paper, a time series forecasting approach by integrating particle swarm optimization (PSO) and support vector regression (SVR) is proposed. SVR has been widely applied in time series predictions. However, no general guidelines are available to choose the free parameters of an SVR model. The proposed approach uses PSO to search the optimal parameters for model selections in the hope of improving the performance of SVR. In order to evaluate the performance of the proposed approach, the TAIEX (Taiwan Stock Exchange Capitalization Weighted Stock Index) closing cash index is used as the illustrative example. Experimental results show that the proposed model outperforms the traditional SVR model and provides an alternative in financial time series forecasting.
The Application of Geophysical Techniques at Wroxeter, Roman City

This paper provides an overview of the geophysical research that has been carried out at the Roman city of Wroxeter (Viroconium) in Shropshire over the past three years, stimulated by the Wroxeter Hinterland Project directed by Birmingham University Field Archaeology Unit (BUFAU). A major part of this geophysical work has been the completion of a fluxgate gradiometer survey over the entire 75 hectare area within the city defences, to build up a complete magnetic map of the remains. The results of this survey are presented and some of the key features identified during initial analysis are discussed. Further investigations, on a smaller scale, have also been undertaken with a range of other geophysical techniques; these are summarised and, where possible, initial results are presented. A strategy for the archaeological interpretation of such a large geophysical dataset is outlined and the research agenda for the geophysics is reviewed and some suggestions made concerning the analytical strength of each
Dynamic formation of Rydberg aggregates at off-resonant excitation

The dynamics of a cloud of ultra-cold two-level atoms is studied at off-resonant laser driving to a Rydberg state. We find that resonant excitation channels lead to strongly peaked spatial correlations associated with the buildup of asymmetric excitation structures. These aggregates can extend over the entire ensemble volume, but are in general not localized relative to the system boundaries. The characteristic distances between neighboring excitations depend on the laser detuning and on the interaction potential. These properties lead to characteristic features in the spatial excitation density, the Mandel $Q$ parameter, and the total number of excitations. As an application an implementation of the three-atom CSWAP or Fredkin gate with Rydberg atoms is discussed. The gate not only exploits the Rydberg blockade, but also utilizes the special features of an asymmetric geometric arrangement of the three atoms. We show that continuous-wave off-resonant laser driving is sufficient to create the required spatial arrangement of atoms out of a homogeneous cloud.
