description: The purpose of this paper is to propose a method of estimating the import contribution rate. The import contribution is a factor that should be considered in calculating the direct payment for damage. The decline in prices is caused by the combination of various factors. In this case, the decomposition of various factors can confirm the price drop due to the increase in imports. To this end, we set up a partial equilibrium model for individual markets and decompose various factors contributing to the price decline using the equilibrium displacement model. Various types of elasticities are needed to calculate the import contribution rate derived from EDM. Because elasticity has a wide spectrum depending on the purpose of the study or the data used, a cautious approach is needed to obtain objective figures.

description: Majorana bound states are interesting candidates for applications in topological quantum computation. Low energy models allowing to grasp their properties are hence conceptually important. The usual scenario in these models is that two relevant gapped phases, separated by a gapless point, exist. In one of the phases, topological boundary states are absent, while the other one supports Majorana bound states. We show that a customary model violates this paradigm. The phase that should not host Majorana fermions supports a fractional soliton exponentially localized at only one end. By varying the parameters of the model, we describe analytically the transition between the fractional soliton and two Majorana fermions. Moreover, we provide a possible physical implementation of the model. We further characterize the symmetry of the superconducting pairing, showing that the odd-frequency component is intimately related to the spatial profile of the Majorana wavefunctions.

description: America’s small businesses are important drivers of the national economy and job creation. Small firms employ half of the United States (U.S.) labor force and since 1995 small businesses have provided approximately 65 percent of net new jobs in the American economy. Moreover, since the Great Recession small businesses have contributed to a significant proportion of American job recovery (Mills and McCarthy, 2014). While small businesses are vital to the American economy, it is often difficult for lenders to determine the credit worthiness of these types of businesses (Craig, Jackson and Thomson, 2007). To help stimulate lending to small businesses, in 1953 Congress created the U.S. Small Business Administration (SBA) to facilitate the deployment of credit to small firms. Two cornerstone SBA efforts have been the 7(a) and 504 loan guaranteed programs.1 These programs minimize risk by providing federal guarantees, ranging from 40 percent to 75 percent of the origination amount, on loans made by private lenders. These programs have been critical in facilitating loans to America’s small businesses. Without these programs many small businesses might not have otherwise received loans on reasonable terms. Since 2009, these programs have deployed over $122 billion in small business credit combined. In the 21st century the SBA loan guaranteed programs face two challenges: equity and efficiency. Since the end of the Great Recession, the proportion of loans to African Americans has declined, while loan volume has increased. Some in the mainstream media claim that African American small firms are missing out on America’s economic recovery. Additionally, there is a scholarly debate as to whether SBA lending provides economic benefits to areas. Some studies suggest that SBA lending is positively associated with economic growth and employment, while others point to a negative association. This white paper explores some of the equity and efficiency concerns associated with the SBA lending programs and provides recommendations to increase the portion of government guaranteed loans going to African Americans and presents research ideas to further investigate the relationship between SBA lending and local economic growth.

 Material examined – The species was obtained during sampling directly from nest of ants in fruit orchards of Kangarlo village, vicinity of Gara Sou river, near Meshguin shahr, Ardabil province, northwestern Iran, 38° 21' 00.0" N 47° 28' 12.0" E. One female were removed from a vial containing more than 25 ants of Formica sp., 15 July 2015, leg. M. Sobhi.
 Distribution – Czech Republic, Ukraine, Belarus, Russia, all associated with Formica rufa Linnaeus, 1761, F. pratensis Retzius, 1783, and F. polyctena Forster, 1850 (Mahunka 1967; Sevastianov 1978; Khaustov 2014; Khaustov and Tolstikov 2016); Iran, associated with Formica sp. (current study).
 Remarks – This species was originally described by Mahunka (1967) from Czech Republic. Mahunka (1967) described this species in the genus Pygmephorus Kramer (Pygmephoridae). Subsequently, he placed it in the genus Brennandania Sasa, 1961 (Microdispidae) (Mahunka 1972). Later on, Sevastianov (1978) transferred this species in the genus Petalomium Cross, 1965 (Neopygmephoridae), whereas, finally, Khaustov (2014) accommodated it in the genus Caesarodispus. This is a new record for the mite fauna of Iran.

description: Agriculture is the major income source in many developing countries. Official development assistance (ODA) contributes to agricultural development in those countries to alleviate poverty and hunger. Among the significant ODA donors, the Republic of Korea holds a unique position with its transformation from a recipient to a donor. The main objective of this article is to examine Korea’s grants-based ODA disbursements to agricultural sectors for its contribution to agricultural development and food security in its recipients. The data for analysis were collected from the KOICA Statistics Service and OECD DAC Query Wizard for International Development Statistics for agricultural sectors. Results showed Korea continued disbursing the largest share of its agricultural grants to Asia while gradually shifting its investment to Africa. Other regions received relatively small amounts of agricultural aid. However, within regional disbursements to agricultural sectors, each region received distinct shares by aid type, based on their needs and Korea’s national interest or aid policy. For agricultural capacity-building, the analysis identified evolution of the training program’s main focus over the last 25 years. This shift from technical capacity improvement to software one indicated Korea’s efforts to better align its aid policy with international norms for aid effectiveness.

description: We present a new set of solar metallicity atmosphere and evolutionary models for very cool brown dwarfs and self-luminous giant exoplanets, which we term ATMO 2020. Atmosphere models are generated with our state-of-the-art 1D radiative-convective equilibrium code ATMO, and are used as surface boundary conditions to calculate the interior structure and evolution of $0.001-0.075\,\mathrm{M_{\odot}}$ objects. Our models include several key improvements to the input physics used in previous models available in the literature. Most notably, the use of a new H-He equation of state including ab initio quantum molecular dynamics calculations has raised the mass by $\sim1-2\%$ at the stellar-substellar boundary and has altered the cooling tracks around the hydrogen and deuterium burning minimum masses. A second key improvement concerns updated molecular opacities in our atmosphere model ATMO, which now contains significantly more line transitions required to accurately capture the opacity in these hot atmospheres. This leads to warmer atmospheric temperature structures, further changing the cooling curves and predicted emission spectra of substellar objects. We present significant improvement for the treatment of the collisionally broadened potassium resonance doublet, and highlight the importance of these lines in shaping the red-optical and near-infrared spectrum of brown dwarfs. We generate three different grids of model simulations, one using equilibrium chemistry and two using non-equilibrium chemistry due to vertical mixing, all three computed self-consistently with the pressure-temperature structure of the atmosphere. We show the impact of vertical mixing on emission spectra and in colour-magnitude diagrams, highlighting how the $3.5-5.5\,\mathrm{μm}$ flux window can be used to calibrate vertical mixing in cool T-Y spectral type objects.

description: Marine and coastal ecosystems provide a wide variety of recreational opportunities that are highly valued by society. For the purposes of conducting a meta-analysis we build an extensive global dataset of marine recreational ecosystem service values from the literature. Using this database we developed a number of meta-regression specifications with the objective of evaluating the study specific effects of location, ecosystem, valuation methodology and statistical estimation methods on the reported value estimates. Furthermore, the paper investigates if cultural differences between studies are an important determinant that should be considered in international (metaanalytical) value transfer. This was achieved by including a number of cultural parameters from previous societal studies and surveys into our meta-regression models. We found that accounting for differences in cultural dimensions across recreation valuation studies had a significant influence on value estimates. While a multi-level modelling approach that controls for study effects, proved to be a better fit than a standard one level specification, we found that the absolute in-sample transfer errors associated with the standard OLS model were slightly less on average based on the differences between the actual and predicted values in our meta-database.

description: We present an optical, X-ray, and $γ$-ray study of 1SXPS J042749.2-670434, an eclipsing X-ray binary which has an associated $γ$-ray counterpart, 4FGL J0427.8-6704. This association has led to the source being classified as a transitional millisecond pulsar (tMSP) in an accreting state. We analyse 10.5 years of Fermi LAT data, and detect a $γ$-ray eclipse at the same phase as optical and X-ray eclipses at the >5$σ$ level, a significant improvement on the 2.8$σ$level of the previous detection. The confirmation of this eclipse solidifies the association between the X-ray source and the $γ$-ray source, strengthening the tMSP classification. However, analysis of several optical data sets and an X-ray observation do not reveal a change in the source's median brightness over long timescales or a bi-modality on short timescales. Instead, the light curve is dominated by flickering which has a correlation time of 2.6 min alongside a potential quasi-periodic oscillation at $\sim$21 min. The mass of the primary and secondary star are constrained to be $M_1=1.43^{+0.33}_{-0.19}$ M$_{\odot}$ and $M_2=0.3^{+0.17}_{-0.12}$ M$_{\odot}$ through modelling of the optical light curve. While this is still consistent with a white dwarf primary, we favour the transitional millisecond pulsar in a low accretion state classification due to the significance of the $γ$-ray eclipse detection.

description: Data from a long term field experiment were used to develop a predictive equation relating maize grain yield to nitrogen (N) and phosphate (P) applications, and total precipitation (RI) in different growth stages.of the maize plant. These stages were a pre-planting period, followed by a sequence of non-overlapping physiological growth phases from sowing to maturity. The equation was a mixed quadratic (N) and square-root (P) polynomial containing linear RI, Ri*N and RIP terms. The function was used to determine the response of maize grain yields to N and P, the fertilizer requirements for maximum profits and least cost N and P combinations. The effects of Low, Median, and High levels of rainfall were also investigated. It was found that yield response and profitability were adversely affected by increased levels of precipitation. The results indicate the importance of considering rainfall in fertilizer recommendations

description: Particle competition and cooperation (PCC) is a graph-based semi-supervised learning approach. When PCC is applied to interactive image segmentation tasks, pixels are converted into network nodes, and each node is connected to its k-nearest neighbors, according to the distance between a set of features extracted from the image. Building a proper network to feed PCC is crucial to achieve good segmentation results. However, some features may be more important than others to identify the segments, depending on the characteristics of the image to be segmented. In this paper, an index to evaluate candidate networks is proposed. Thus, building the network becomes a problem of optimizing some feature weights based on the proposed index. Computer simulations are performed on some real-world images from the Microsoft GrabCut database, and the segmentation results related in this paper show the effectiveness of the proposed method.

description: We introduce an analogue of the Novikov Conjecture on higher signatures in the context of the algebraic geometry of (nonsingular) complex projective varieties. This conjecture asserts that certain "higher Todd genera" are birational invariants. This implies birational invariance of certain extra combinations of Chern classes (beyond just the classical Todd genus) in the case of varieties with large fundamental group (in the topological sense). We prove the conjecture under the assumption of the "strong Novikov Conjecture" for the fundamental group, which is known to be correct for many groups of geometric interest. We also show that, in a certain sense, our conjecture is best possible.

description: This article delineates the principles for obtaining optimal control policies based on dynamic plant growth models. It starts with a brief outline of the structure of decision problems and the resulting requirements for models designed to support these decisions. The concepts of open-loop and closed-loop control are discussed next. Emphasis is placed on the methods for solving the control problem. Three basic frameworks are considered including Pontrjagin's Maximum Principle, Dynamic Programming and the use of Numerical Optimization methods. The article outlines the principle structure of these approaches and addresses their strengths and weaknesses. It concludes with an application of Numerical Optimization methods to greenhouse temperature strategies. The results demonstrate how the algorithms work and lead to conclusions with respect to their applicability for research purposes and practical decision-making.

description: (Shortened) We present R-band photometry of the X-ray transient and candidate black hole binary XTE J1650-500 obtained between 2003 May and August with the 6.5m Clay Telescope. A timing analysis of these data reveals a photometric period of 0.3205 +/- 0.0007 days (i.e. 7.63 hr) with a possible alias at 0.3785 days (9.12 hr). Our photometry completely rules out the previously published spectroscopic period of 0.212 days (5.09 hr). Consequently, we reanalyzed the 15 archival ESO/VLT spectra (obtained 2002 June by Sanchez-Fernandez et al.) that were the basis of the previously published spectroscopic period. We used a ``restframe search'' technique that is well suited for cases when the signal-to-noise ratio of individual spectra is low. The results confirmed the photometric period of 0.3205 days, and rule out the alias period near 0.38 days. The best value for the velocity semiamplitude of the companion star is K_2 = 435 +/- 30 km/sec, and the corresponding optical mass function is f(M) = 2.73 +/- 0.56 solar masses. The amplitude of the phased R-band light curve is 0.2 magnitudes, which gives a lower limit to the inclination of 50 +/- 3 degrees in the limiting case of no contribution to the R-band light curve from the accretion disk. If the mass ratio of XTE J1650-500 is similar to the mass ratios of other black hole binaries like A0620-00 or GRS 1124-683 (e.g. Q >~ 10), then our lower limit to the inclination gives an upper limit to the mass of the black hole in XTE J1650-500 of M_1

description: In real-world problems, uncertainties (e.g., errors in the measurement, precision errors) often lead to poor performance of numerical algorithms when not explicitly taken into account. This is also the case for control problems, where optimal solutions can degrade in quality or even become infeasible. Thus, there is the need to design methods that can handle uncertainty. In this work, we consider nonlinear multi-objective optimal control problems with uncertainty on the initial conditions, and in particular their incorporation into a feedback loop via model predictive control (MPC). In multi-objective optimal control, an optimal compromise between multiple conflicting criteria has to be found. For such problems, not much has been reported in terms of uncertainties. To address this problem class, we design an offline/online framework to compute an approximation of efficient control strategies. This approach is closely related to explicit MPC for nonlinear systems, where the potentially expensive optimization problem is solved in an offline phase in order to enable fast solutions in the online phase. In order to reduce the numerical cost of the offline phase, we exploit symmetries in the control problems. Furthermore, in order to ensure optimality of the solutions, we include an additional online optimization step, which is considerably cheaper than the original multi-objective optimization problem. We test our framework on a car maneuvering problem where safety and speed are the objectives. The multi-objective framework allows for online adaptations of the desired objective. Alternatively, an automatic scalarizing procedure yields very efficient feedback controls. Our results show that the method is capable of designing driving strategies that deal better with uncertainties in the initial conditions, which translates into potentially safer and faster driving strategies.

Does marriage really matter? Investments in prenatal care and birth outcomes
Creators: name: Jacknowitz, Alison

Publisher: name: American University
Year: 2023

description: Nonmarital childbearing has increased dramatically in the United States in recent decades. A great deal of attention has been paid by both academics and policy makers to this increase, in part because of concerns that having a single mother negatively affects child outcomes. We use the Early Childhood Longitudinal Study-Birth Cohort (ECLS-B) to investigate whether marriage is associated with greater investments in prenatal care and better birth outcomes, and the extent to which this “marriage effect” is heterogeneous. Our results suggest that marriage is significantly and positively correlated with investments in prenatal care and birth outcomes. However, we find a great deal of heterogeneity in these relationships. Unmarried motherhood among educated mothers (those with a college degree or higher) is not associated with lower levels of investment in prenatal care nor with negative birth outcomes. There is also heterogeneity across racial and ethnic groups in the marital status effect that differs by which outcome is being examined. We also find that including observable characteristics and addressing unobserved characteristics reduces but does not eliminate the positive correlation between marital status and prenatal care investments, but that these remaining differentials in investments do not appear to translate into significant differences in infant health outcomes. This variation in marital status effects suggests that the benefits of marriage may be overstated, and that policy efforts to improve children’s well-being through promoting marriage might be reexamined to take this into account.

description: We use first principles density functional theory to calculate electronic and magnetic properties of TiF3 using the full potential linearized augmented plane wave method. The LDA approximation predicts a fully saturated ferromagnetic metal and finds degenerate energy minima for high and low symmetry structures. The experimentally observed Jahn-Teller phase transition at Tc=370K can not be driven by the electron-phonon interaction alone, which is usually described accurately by LDA. Electron correlations beyond LDA are essential to lift the degeneracy of the singly occupied Ti t2g orbital. Although the on-site Coulomb correlations are important, the direction of the t2g-level splitting is determined by the dipole-dipole interactions. The LDA+U functional predicts an aniferromagnetic insulator with an orbitally ordered ground state. The input parameters U=8.1 eV and J=0.9 eV for the Ti 3d orbital were found by varying the total charge on the TiF$_6^{2-}$ ion using the molecular NRLMOL code. We estimate the Heisenberg exchange constant for spin-1/2 on a cubic lattice to be approximately 24 K. The symmetry lowering energy in LDA+U is about 900 K per TiF3 formula unit.

description: International police cooperation is facing a new and serious challenge, as the fight against current emerging security threats (terrorism, foreign fighters, radicalization and extremism) in the world and in Europe requires a real time, non-bureaucratic information exchange among all countries' all law enforcement agencies without geographical limitation. The report aims to introduce briefly the methods of international police cooperation, focusing on the advantages and disadvantages of information exchange conducted by PCCCs within the European Union (EU) and in the Western Balkan region. The main objective of the document is to ascertain, whether the current situation in the field of PCCCs in the Western Balkans fulfils the requirement of the above-mentioned criteria, such as the capability to conduct real time data exchange without geographical limits. To find this out, we will analyse the state of play, reveal strengths and weaknesses of the system, and will elaborate a way forward to an enhanced and effective information exchange, that can ensure the overall goal; to increase the efficiency of LEAs in their fight against terrorism and Transnational Threats (TNT).

description: Nonmarital childbearing has increased dramatically in the United States in recent decades. A great deal of attention has been paid by both academics and policy makers to this increase, in part because of concerns that having a single mother negatively affects child outcomes. We use the Early Childhood Longitudinal Study-Birth Cohort (ECLS-B) to investigate whether marriage is associated with greater investments in prenatal care and better birth outcomes, and the extent to which this “marriage effect” is heterogeneous. Our results suggest that marriage is significantly and positively correlated with investments in prenatal care and birth outcomes. However, we find a great deal of heterogeneity in these relationships. Unmarried motherhood among educated mothers (those with a college degree or higher) is not associated with lower levels of investment in prenatal care nor with negative birth outcomes. There is also heterogeneity across racial and ethnic groups in the marital status effect that differs by which outcome is being examined. We also find that including observable characteristics and addressing unobserved characteristics reduces but does not eliminate the positive correlation between marital status and prenatal care investments, but that these remaining differentials in investments do not appear to translate into significant differences in infant health outcomes. This variation in marital status effects suggests that the benefits of marriage may be overstated, and that policy efforts to improve children’s well-being through promoting marriage might be reexamined to take this into account.

Road traffic collisions prevention
Neurotrauma prevention
India
Key informant perspectives

description: Abstract: Background: Despite current preventative strategies, road traffic collisions (RTCs) and resultant neurotrauma remain a major problem in India. This study seeks to explore local perspectives in the context within which RTCs take place and identify potential suggestions for improving the current status. Methods: Ten semi-structured interviews were carried out with purposively selected key informants from the city of Visakhapatnam, Andhra Pradesh. Participants were from one of the following categories: commissioning stakeholders; service providers; community or local patient group/advocacy group representatives. Transcripts from these interviews were analysed qualitatively using the Framework Method. Results: Participants felt RTCs are a serious problem in India and a leading cause of neurotrauma. Major risk factors identified related to user behaviour such as speeding and not using personal safety equipment, and the user state, namely drink driving and underage driving. Other reported risk factors included poor infrastructure, moving obstacles on the road such as other vehicles, pedestrians and animals, overloaded vehicles and substandard safety equipment. Participants discussed how RTCs affect not only the health of the casualty, but are also a burden to the healthcare system, families, and the national economy. Although there are ongoing preventative strategies being carried out by both the government and the community, challenges to successful prevention emerged from the interviews which included resource deficiencies, inconsistent implementation, lack of appropriate action, poor governance, lack of knowledge and the mindset of the community and entities involved in prevention. Recommendations were given on how prevention of RTCs and neurotrauma might be improved, addressing the areas of education and awareness, research, the pre-hospital and trauma systems, enforcement and legislation, and road engineering, in addition to building collaborations and changing mindsets. Conclusions: RTCs remain a major problem in India and a significant cause of neurotrauma. Addressing the identified gaps and shortfalls in current approaches and reinforcing collective responsibility towards road safety would be the way forward in improving prevention and reducing the burden.

description: Permutation entropy measures the complexity of deterministic time series via a data symbolic quantization consisting of rank vectors called ordinal patterns or just permutations. The reasons for the increasing popularity of this entropy in time series analysis include that (i) it converges to the Kolmogorov-Sinai entropy of the underlying dynamics in the limit of ever longer permutations, and (ii) its computation dispenses with generating and ad hoc partitions. However, permutation entropy diverges when the number of allowed permutations grows super-exponentially with their length, as is usually the case when time series are output by random processes. In this Letter we propose a generalized permutation entropy that is finite for random processes, including discrete-time dynamical systems with observational or dynamical noise.

description: Snakes can move through almost any terrain. Similarly, snake robots hold the promise as a versatile platform to traverse complex environments like earthquake rubble. Unlike snake locomotion on flat surfaces which is inherently stable, when snakes traverse complex terrain by deforming their body out of plane, it becomes challenging to maintain stability. Here, we review our recent progress in understanding how snakes and snake robots traverse large, smooth obstacles that lack anchor points for gripping or bracing. First, we discovered that the generalist variable kingsnake combines lateral oscillation and cantilevering. Regardless of step height and surface friction, the overall gait is preserved. Next, to quantify static stability of the snake, we developed a method to interpolate continuous body in three dimensions (both position and orientation) between discrete tracked markers. By analyzing the base of support using the interpolated continuous body 3-D kinematics, we discovered that the snake maintained perfect stability during traversal, even on the most challenging low friction, high step. Finally, we applied this gait to a snake robot and systematically tested its performance traversing large steps with variable heights to further understand stability principles. The robot rapidly and stably traversed steps nearly as high as a third of its body length. As step height increased, the robot rolled more frequently to the extent of flipping over, reducing traversal probability. The absence of such failure in the snake with a compliant body inspired us to add body compliance to the robot. With better surface contact, the compliant body robot suffered less roll instability and traversed high steps at higher probability, without sacrificing traversal speed. Our robot traversed large step-like obstacles more rapidly than most previous snake robots, approaching that of the animal.

description: Reductions in the terms of trade results in shifts in relative profitibility and thus in economic activity. Import substituting industries are benefiting relative to export industries. Since the mid seventies there were deteriorations in the international terms of trade and the domestic terms of trade of RSA's agriculture, especially that of agricultural primary products. The deterioration of the RSA exchange rate were since 1983 sufficient to compensate for inflation differentials, but agriculture experienced increasing financial pressure. More refinement of agricultural products may benefit agriculture. The South African agriculture has to concentrate on qualitative competition.

description: Over the past 35 years the gap in poverty between divorced and married women increased from 2:1 (in 1967) to 4:1 (in 2001). Despite high poverty rates, divorced women are no less educated than married women. Labor market earnings are a particularly important source of income for elderly divorced women; Divorced women's level of labor force participation is comparable to that of married men; however, retirement of divorced women experiences no spike at ages 62 and 65, as is the case for married men. Divorced women are quite distinct from separated women, with the latter much less educated, lower income, and minority; grouping these two populations together, as is often done, is a mistake. Initial analyses suggest that the reduction in the requirement on length of marriage from 20 to 10 years to receive Social Security divorcee benefits had little or no effect on alleviating divorcee poverty. A large number of questions remain unanswered, but given the speed at which the cohorts with high prevalence of divorce are approaching old age, the time is now to address these questions.
