Outcrop analogue of Pre-salt microbial series from South Atlantic: the Yacoraite Fm, Salta rift system (NW Argentina)

The post-rift geological history of the South Atlantic Ocean is attracting geoscientists attention since exploration in the Brazilian pre-salt has resulted in important oil discovery for the past 4 years. The main reservoirs correspond to stromatolitic and bioclastic carbonate facies which were deposited in lacustrine to shallow marine depositional environments during the Sag phase. As only few subsurface data are available, the reservoir distribution as well as the reservoir heterogeneities are poorly constrained in a such peculiar setting. The present study is thus focused on the Yacoraite Fm, a carbonate-dominated series, that has been deposited during the sag phase of the Salta rift system, NW Argentina, and that represents an excellent outcrop analogue for these reservoirs. Indeed, the Yacoraite Formation shows a large diversity of stromatolitic facies that exhibit various sizes, macroscopic morphologies and microscopic textures.
Macroeconomic Uncertainty and Economic Development A cross-country Panel Data Analysis

We study how macroeconomic uncertainty hinders economy’s development and show that one standard deviation increase in macroeconomic uncertainty reduces GDP by about 1.5 percent and productivity by about 3.5 percent. Despite commonly believed in literature, we show R&D (investment) expenditure channel only partially transmits (does not transmit) the impact of uncertainty to production. We show more developed countries face less macroeconomic uncertainty levels but are more sensitive to changes in them.

N ov 2 02 1 A Resolution of St . Petersburg Paradox

The St. Petersburg paradox is the oldest paradox in decision theory and has played a pivotal role in the introduction of increasing concave utility functions embodying risk aversion and decreasing marginal utility of gains. All attempts to resolve it have considered some variants of the original set-up, but the original paradox has remained unresolved, while the proposed variants have introduced new complications and problems. Here a rigorous mathematical resolution of the St. Petersburg paradox is suggested based on a probabilistic approach to decision theory. JEL classification: G11, G12
WHO MANAGES FINANCIAL RISK? AN EMPIRICAL EXAMINATION OF RISK MANAGEMENT PRACTICES IN THE ROMANIAN METALLURGICAL INDUSTRY

The aim of the paper is to analyze risk management practice adopted by the Romanian metallurgical enterprises and to identify new tools for hedging price risk. Romanian metallurgical companies recognize the main risks that their businesses are facing: increased prices of raw materials and energy, foreign exchange risk, and lower (domestic) demand for company’s products. Another important fi is that the perception of fi nancial risks has improved in the last years and the companies started to use fi nancial derivatives in order to hedge some fi nancial risks. Nevertheless, Romanian metallurgical companies have proved to be reluctant to fully implement and adhere to suffi cient risk management practices.
Does assisted reproductive technology increase adverse perinatal outcome in preterm twins? A hospital based comparative study at single tertiary center in Croatia

Objective: The aim of this study is to investigate the association of assisted reproductive technology (ART) as an independent risk factor for obstetric complications and perinatal outcome in preterm twin pregnancies in 5 years period at a single tertiary center. Methods: We collected the data (from maternal and neonatal medical records) from 88 preterm twin pregnancies conceived after ART and 147 preterm twin pregnancies conceived naturally in a 5-year period. Results: Pregnancy complications in ART mainly included preterm premature rupture of membranes, gestational hypertension and gestational diabetes. More than 85% of ART twins were born by caesarean section, significantly higher than non-ART twins (p = 0.005). Neonatal complications in both groups mainly included low Apgar score in 1st minute, perinatal infections, respiratory distress syndrome (RDS) and hyperbilirubinemia and the incidences of these complications were comparable between the groups. According to Weinberg’s differential rule, there were 32 monozygotic ART twins and 119 monozygotic non-ART twins. This represents a monozygotic twin rate of 4.7% for ART births and 0.6% for non-ART births. Conclusion: Our results indicated that ART procedures were not associated with adverse perinatal outcome and that ART is not associated with increased obstetric complications in preterm twins followed and born in a single tertiary center.

Undrained Shear Strength cu and Undrained Elastic Modulus Eu of Anthropogenic Soils from Laboratory Tests

Undrained shear strength cu and undrained elasticity modulus Eu are one of the basic mechanical parameters describing soil properties in engineering practice. In a simple way cu can be established by fall cone test or, similar as the Eu modulus, can be determined from the stress-strain curve obtained from the uniaxial or triaxial compression tests. The paper presents the results of laboratory tests od cu and Eu parameters carried out on anthropogenic soil in uniaxial compression tests and fall cone tests. The soil used in the study represented different types of materials used in earthworks - containing different share of clay fraction. Tests were provided on the soil in different bulk density and water contents. The paper proposes a method of estimating Eu50 on the basis of cone penetrometer tests. Such test does not require any additional preparation and can be performed directly on the soil compacted in the cylinder of the Proctor’s apparatus, which allows for a quick assessment of the soil elasticity parameters.
Assessing the safety of existing structures: reliability based assessment framework, examples and application

Abstract Safety, reliability and risk are key issues in the preservation of our built, cultural heritage. Several structural collapses make us aware of the vulnerability of our technical and natural environment and demand an adequate engineering response. In the analysis phase, an objective way to assess the safety of the structure is essential. The present raises the need for a reliability based assessment framework for existing masonry structures. Although this field of research is relatively young, different techniques have been proposed and optimised. These permit to calculate the global probability of failure of complex structures, relying on deterministic techniques able to calculate the stability state for a prescribed set of parameters. This paper illustrates how these techniques can be a valid tool to evaluate the bearing capacity of existing structures. Focus is on reliability methods based on simulation procedures (Monte Carlo, Directional Sampling), combined with an adaptive meta‐model (Respon.

In monotherapy, paracetamol was the most dispensed molecule with 20.2% followed by tramadol with 18.87% among which 4.97% was dispensed for self-medication and 13.91% by prescription. Fixed combination Paracetamol/Codeine was the most dispensed by prescription with 16.56% and 9.93% for self-medication. 1.32% of the fixed combination Paracetamol/Tramadol was demanded for self-medication and 7.62% by prescription. We observed a hight non-compliance with the rules of dispensing analgesics from List I with 32.02% by self-medication. Conclusion: The main molecules solicited with or without prescription were paracetamol/codeine, paracetamol and tramadol. There is also a high over-the-counter dispensing of list I analgesics.
Paradigm Shift? Open Innovation and the Innovative Performance of EU Firms

It has been suggested that a paradigm shift is taking place, from the old model of product innovation based on in-house R&D, to a new model based on the intensive use of external sources (search depth). We test this using Eurostat CIS4 data for 40 sectors in 18 European countries. The findings of estimated GLM models suggest a more nuanced understanding of the role of external search is required. Internal R&D, rather than external search depth, are found to be the key factors affecting the performance of innovation leaders. Further, we find no evidence of a substitution effect between R&D and external sources for innovation leaders. External search is identified as an important factor affecting the performance of innovation followers. There is also evidence of a substitution effect amongst these particular firms, indicating they replace formal R&D with openness, in order to acquire the information needed to catch-up with innovation leaders. These findings are consistent with the old innovation model, cautioning against the suggestion that a paradigm shift has occurred.
Climate in Software Development Teams: Role of Task Interference and Procedural Justice

IntroductionThe software industry is a significant contributor to India’s economic growth. Though the Indian software industry is growing at a tremendous rate, there are some macro- and micro-level challenges which have to be addressed. In most cases, software development is project-based, where the projects are handled by project teams. In order to improve the quality and efficiency of team outcomes we have to focus on the work-related and interpersonal processes of those software development teams. Especially team climate is a crucial factor which can influence the performance of the teams. Over the past three decades, the concept of climate has been a special area of focus for applied psychologists and organizational sociologists (Anderson & West, 1998). According to Anderson and West (1998), interaction between individuals, common goals, and task interdependence are some of the necessary conditions which can create shared understandings and behavioural expectations among the members.Team climate is found to be a crucial determinant of team performance (Agrell & Gustafson, 1994; Anderson & West, 1998) and an important predictor of work team innovation (Burningham & West, 1995). Since innovativeness is a crucial component of software development tasks, the significance of team climate in software development teams is very high.Research ObjectiveThe objective of the current study was to understand the effect of task interdpedence on the climate of software development teams and the moderating effect of procedural justice in this relationship.
The effects of bump height on the reliability of ACF in flip‐chip

In this study, flip‐chip (FC) assemblies on printed circuit board (PCB) and flex, with bump heights of 4, 20 and 40μm, and with a constant copper pad height were compared by modelling of the bonding process and of thermal cycling from –40 to 1258C. The stress distributions of the assemblies were analysed and it was found that the largest stresses occurred for the smallest bump height. The stresses in the anisotropic conductive film for the FC‐on‐flex assembly were also found to be generally larger than for the FC‐on‐PCB.
Individual blade pitch control of floating offshore wind turbines

Floating wind turbines offer a feasible solution for going further offshore into deeper waters. However, using a floating platform introduces additional motions that must be taken into account in the design stage. Therefore, the control system becomes an important component in controlling these motions. Several controllers have been developed specifically for floating wind turbines. Some controllers were designed to avoid structural resonance, while others were used to regulate rotor speed and platform pitching. The development of a periodic state space controller that utilizes individual blade pitching to improve power output and reduce platform motions in above rated wind speed region is presented. Individual blade pitching creates asymmetric aerodynamic loads in addition to the symmetric loads created by collective blade pitching to increase the platform restoring moments. Simulation results using a high-fidelity non-linear turbine model show that the individual blade pitch controller reduces power fluctuations, platform rolling rate and platform pitching rate by 44%, 39% and 43%, respectively, relative to a baseline controller (gain scheduled proportional–integral blade pitch controller) developed specifically for floating wind turbine systems. Turbine fatigue loads were also reduced; tower side–side fatigue loads were reduced by 39%. Copyright © 2009 John Wiley & Sons, Ltd.
Benchmarking Multiconfiguration Dirac–Hartree–Fock Calculations for Astrophysics: Si-like Ions from Cr xi to Zn xvii

The multiconfiguration Dirac–Hartree–Fock (MCDHF) and relativistic configuration interaction methods are used to provide excitation energies, lifetimes, and radiative transition data for the 604 (699, 702, 704, 704, 704, and 699) lowest levels of the 3s 23p 2, 3s3p 3, 3s 23p3d, 3p 4, 3s3p 23d, 3s 23d 2, 3p 33d, 3s3p3d 2, 3s3d 3, 3p3d 3, 3p 23d 2, 3s 23p4s, 3s 23p4p, 3s 23p4d, 3s 23p4f, 3s3p 24s, 3s3p 24p, 3s3p 24d, 3s3p 24f, 3s 23d4s, 3s 23d4p, 3p 34s, 3p 34p, 3s3p3d4s, 3s 23p5s, and 3s 23p5p configurations in Cr xi, (Mn xii, Fe xiii, Co xiv, Ni xv, Cu xvi, and Zn xvii). Previous line identifications of Fe xiii and Ni xv in the EUV and X-ray wavelength ranges are reviewed by comprehensively comparing the MCDHF theoretical results with available experimental data. Many recent identifications of Fe xiii and Ni xv lines are confirmed, and several new identifications for these two ions are proposed. A consistent atomic data set with spectroscopic accuracy is provided for the lowest hundreds of levels for Si-like ions of iron-group elements of astrophysical interest, for which experimental values are scarce. The uncertainty estimation method suggested by Kramida, applied to the comparison of the length and velocity line strength values, is used for ranking the transition data. The correlation of the latter with the gauge dependency patterns of the line strengths is investigated.
A Schematic Model of Low Temperature and High Salinity Seawaters in Southern Java of the Indian Ocean during ENSO-IOD 2017

The semi-peRmanent jAva coasTal Upwelling that is known as RATU, it was named semi-permanent because upwelling does not occur every month of the year in Southern Java has been investigated by several international researchers. However, this study focused on investigating the horizontal distribution of upwelling areas, using the indicator of low temperature (max. ∼26°C) and high salinity (min. 34 PSU) seawater mass, in different depth layers. The datasets were obtained from HYCOM, with the wind daily as well as the monthly ONI, SOI ENSO, and DMI datasets obtained from ECMWF, NOAA, BoM Australia, and Jamstec, respectively. Furthermore, the horizontal propagation of the low temperature and high salinity in 2017 at depths of 0 m, 50 m, 75 m, 125 m, 150 m, and 300 m have been observed and modeled as schematics. According to the results, the probable upwelling area begins from 150/125 meters to 75/50 meters layer depth. In these layers, the horizontal propagation from the east monsoon (July) to the transition monsoon (October) dominantly begins from the east and moves westward. This shows the highest correlation between temperature/salinity and SOI occurred from August to October during La Nina, from a depth of 0 m to 100m. Similarly, for the ONI, low temperature and high salinity also occurred from the Normal phase to the La Nina phase. The correlation between temperature/salinity and IOD shows the probable upwelling season occurred during IOD (+) phase until a 100 m depth because salinity becomes more irregular with increasing ocean depth.
Musical syntactic structure improves memory for melody: evidence from the processing of ambiguous melodies

Memories of most stimuli in the auditory and other domains are prone to the disruptive interference of intervening events, whereby memory performance continuously declines as the number of intervening events increases. However, melodies in a familiar musical idiom are robust to such interference. We propose that representations of musical structure emerging from syntactic processing may provide partially redundant information that accounts for this robust encoding in memory. The present study employs tonally ambiguous melodies which afford two different syntactic interpretations in the tonal idiom. Crucially, since the melodies are ambiguous, memory across two presentations of the same melody cannot bias whether the interpretation in a second listening will be the same as the first, unless a representation of the first syntactic interpretation is also encoded in memory in addition to sensory information. The melodies were presented in a Memory Task, based on a continuous recognition paradigm, as well as in a Structure Task, where participants reported their syntactic interpretation of each melody following a disambiguating cue. Our results replicate memory-for-melody’s robustness to interference, and further establish a predictive relationship between memory performance in the Memory Task and the robustness of syntactic interpretations against the bias introduced by the disambiguating cue in the Structure Task. As a consequence, our results support that a representation based on a disambiguating syntactic parse provides an additional, partially redundant encoding that feeds into memory alongside sensory information. Furthermore, establishing a relationship between memory performance and the formation of structural representations supports the relevance of syntactic relationships towards the experience of music.
Risk Premiums in Higher-Order Moments and Stock Return Predictability

In this paper, we study risk premiums in higher order moments of financial asset returns in a general equilibrium setting. Extending the model proposed by Drechsler and Yaron[2011] with a stochastic jump intensity in the processes of both the long-run risk factor and the variance of consumption growth rate, we provide explicit representations for the variance and skewness risk premiums in the equilibrium. Moreover, modeling the stochastic jump intensity endogeneously and deriving a representation of the risk-neutral skewness with that intensity, we propose a possible reason of the empirical fact of time-varying and negative riskneutral skewness. Finally, providing an equity risk premium representation of a linear factor pricing model with the variance and skewness risk premiums, we show an empirical evidence in which the skewness risk premium, as well as the variance risk premium, has superior predictive power for future aggregate stock market index returns.
Prevalence and species distribution of ectoparasite of domestic dogs in jimma town, Oromia regional state, southwest Ethiopia

This study investigated the prevalence and the species composition of ectoparasites of dogs in Jimma town, southwest Ethiopia from December 2017 to March 2018. Physical examinations were undergone in 384 dogs and laboratory identification was employed on the ectoparasites. Of the 384 dogs examined, 365 (95.05%) were infested with one or more of ticks, lice or flees. Overall a total of seven different species of flea were recorded in the dogs. The most prevalent ectoparasite identified was Ctenocephalides felis (79.69%) followed by Ctenocephalides canis (71.35%) while the other species collected and identified were Rhipicephalus sanguine (10.42%), Linognathus setosus (7.81%), Pulex irritans (4.17%), Trichodectus canis (2.6%), and Ambylomma spp. (2.6%). The present study showed no statistical significant difference (p>0.05) in the prevalence of ectoparasites between young and adult dogs. However, statistically significant difference (p<0.05) was observed in the prevalence of ectoparasites between male and female dogs. This study revealed that ectoparasites are the major challenges for the dogs in the study area which warrants serious attention.
