Implementing Lindahl Allocations in a Warm-Glow Economy

We provide a novel mechanism that delivers efficient provision of public goods in an economy that may display warm-glow preferences. No information about the fundamentals of the economy is required on the mechanism designer's side, so the mechanism is informationally decentralized. The mechanism is individually rational, single-valued, feasible and continuous, and the Nash equilibria of the mechanism coincide with the Lindahl equilibria of the economy. When no warm-glow preferences are present in the economy, the mechanism fully implements the classical Lindahl allocations.
Information Networks in the Financial Sector and Systemic Risk

We create and test two novel network-based measures of interconnectedness in the financial industry during 1996 to 2013. A network based on informed trading in financial firms predicts firm-specific risk and performance, while one formed on financial firm returns predicts future macroeconomic risk. The measure of informed trading is robust to variable order arrival rates more common in modern algorithmic trading. A trading strategy based on informed trading network centrality in the financial sector delivers an annualized risk-adjusted return of 7.73%. This risk-adjusted return shows that the network centrality has an economic impact that is relevant beyond the statistical results of the paper.
Blockholder Mutual Fund Participation in Private In-house Meetings: Evidence on Social Bonding and Stock Return Volatility

The Shenzhen Stock Exchange (SZSE) in China is unique worldwide in requiring disclosure of the timing, participants, and selected content of private in-house meetings between firm managers and outside investors. We investigate whether these private meetings benefit hosting firms and their major outside institutional investors, blockholder mutual funds (i.e., funds with ownership ≥ 5 percent). Using a large dataset of SZSE firms, we find that blockholder mutual funds have more access to private in-house meetings, and top management is more likely to be present – especially when negative news is disclosed. Further, when blockholder mutual funds attend negative news meetings with top management, they are less likely to sell shares, their investment relationship with the hosting firm lasts longer, and hosting firms experience lower post-meeting stock return volatility. These findings suggest that private in-house meetings are an informative disclosure channel that improves “social bonding” between top management and blockholder mutual funds in ways that benefit both parties.
Acute metabolic and inflammatory responses in active men undergoing postural corrective training

Introduction: The practice of physical exercises has become recurrent throughout life in the search of health promotion. Among numerous methods offered by the fitness market, the Corrective Postural Training TCP aims, through a gymnastics model, to increase adherence to the practice, with a reduced risk of muscle-joint injuries. Objective: To analyze the effects of an initial session of TCP on lactacidemia, blood glucose, heart rate, interleukin-6, tumor necrosis factor-alpha and creatine kinase in healthy individuals without previous experience with the method. Methods: 16 active men, without preexisting diseases (28.5 ± 5.0 years; 72.16 ± 8.1 kg; 1.75 ± 0.06 m and body mass index 23.31 ± 2.1) underwent three visits to the laboratory. Two visits for data collection and one for the TCP session. Results: The session showed stable levels for the variables of blood glucose, creatine kinase, tumor necrosis factor-alpha and interleukin-6. Significant differences were found for lactic acid in the 20’ (4.9 ± 1.5 mmol/L) and 30’ (4.1 ± 1.6 mmol/L) minutes of the session. Conclusion: The evaluated session has no strenuous metabolic and inflammatory levels.
Vitamin D Receptor Binding with DNA in Duodenal Crypt, Duodenal Villi, and Colonic Epithelial Cells of Mice

Vitamin D receptor (VDR) is a transcription factor that mediates calcium absorption by intestinal epithelial cells. Although calcium absorption is ca-nonically thought to occur only in the small intestine, recent studies have shown that VDR activity in the co-lon alone is sufficient to prevent calcium deficiency in mice. Here, we further investigate VDR activity in the colon. We assess VDR-DNA binding in mouse duodenal crypt, duodenal villi, and colonic epithelial cells using Chromatin Immunoprecipitation se-quencing (ChIP-seq). We find that most VDR-respon-sive elements are common to all intestinal epithelial cells, though some VDR-responsive elements are re-gionally-enriched and exhibit greater VDR-binding affinity in either duodenal epithelial cells or colonic epithelial cells. We also assess chromatin accessibil-ity in the same three cell types using Assay for Trans-posase-Accessible Chromatin sequencing (ATAC-seq). By integrating the VDR ChIP-seq and ATAC-seq data, we find that regionally-enriched VDR-re-sponsive elements exhibit greater chromatin acces-sibility in the region of their enrichment. Finally, we assess the transcription factor motifs present in VDR-responsive elements. We find that duodenum- and colon-enriched VDR-responsive elements exhibit different sets of transcription factor motifs other than VDR, suggesting that VDR may act together with dif-ferent partner transcription factors in the two re-gions. Our work is the first investigation of VDR-DNA binding in the colon and provides a basis for further investigations of VDR activity in the colon.
Magnetic Resonance Image Characterization of Knee Meniscus Signal Intensity using Crue’s Approach: Results from a Multi-centre Evidence

This study aimed to characterize knee meniscus signal-intensity using magnetic resonance imaging. Our research included knee MR images of 138 subjects from multi-centres in Nigeria, between September 2016 and December 2017. Knee images were retrieved from patients' folder of MRI scanners and transfered to a DICOM workstation (Onis 2.6) for image analysis. Knee meniscus was characterized into 0, 1, 2 & 3 grades using Crue’s grading approach. Our research revealed 58% incidence of meniscal lesion. Study yielded a significant relationship between meniscal lesion and gender (p <.005) with a greater proportion of these lesions in women than in men. Meniscal lesions showed significant association with osteoarthritis (OA) (p < 0.05). Grade 3 lesions (actual tears) were largely of horizontal configuration.
MULTILEVEL ITEM RESPONSE THEORY ANALYSIS OF THE ANGER REGULATION AND EXPRESSION SCALE: A CROSS-CULTURAL STUDY OF ANGER IN YOUTH

MULTILEVEL ITEM RESPONSE THEORY ANALYSIS OF THE ANGER REGULATION AND EXPRESSION SCALE: A CROSS-CULTURAL STUDY OF ANGER IN YOUTH Tovah Weinrib Anger research among youth is increasingly recognized as an important area to inform guided intervention for children and adolescents with clinical levels of anger. However, most psychometric assessments, including measures of anger, are developed in the United States and are based in Western culture, potentially limiting their efficacy when applied internationally. The Anger Regulation and Expression Scale Short Form (ARES-S) is a comprehensive self-report assessment of the expression and regulation of anger in youth which has been used in research across numerous countries. Using a Multilevel Item Response Theory (MLIRT) approach, we analyzed country specific modulation of the expression of anger by examining the differences in response patterns to the ARES-S between youth from Australia, Greece, Italy, Serbia, South Africa, the United States, and Vietnam. Interestingly, item discrimination between countries varied greatly, indicating differences in anger expression and regulation across these countries. Further, we applied country-specific MLIRT scoring which improved the clinical predictive power of the ARES-S internationally while maintaining a similar predictive power in the United States.
Results of Experiments Carried out on VVER Type Lattices Containing Absorber Rods and their Application for Code Validation

The report presents the results of experiments carried out on hexagonal UO2 lattices containing gadolinium absorber rods and their use in validation of computer codes. The measurements provide possibility to check the prediction of criticality, the modelling of power distribution and some spectral parameters for these strongly perturbed lattices. In the inter-comparison the MULTICELL lattice calculation and COREMICRO finite difference (FD) diffusion code (both are models of the KARATE-440 program system) have been used. Recently these codes have been upgraded by group constant libraries based on ENDF/B-VI nuclear data. The results obtained are in good agreement with the experiments.
Developing Pre-service Elementary Science Teachers’ Science Teaching Efficacy Beliefs through Microteaching by Promoting Efficacy Sources

Science teaching efficacy belief (STEB) is of paramount importance as it motivates teachers to teach science or hinders them from teaching science. Pre-service teachers' efficacy beliefs may change during their method courses. Knowing how pre-service teachers' beliefs change over time can significantly contribute to teacher educators to improve teacher efficacy. This study examined the effect of microteaching on pre-service elementary science teachers' STEB. Pretest-posttest control group design was utilized. Data was collected using the Science Teaching Efficacy Beliefs Instrument (STEBI-B) developed by Enochs and Riggs (1990) both at the beginning and end of the study. The treatment group planned and taught mini-lessons. The lessons were videotaped and evaluated in detail by watching the videotapes. The microteachers replanned and retaught the mini-lessons based on the feedback. The microteaching practices were conducted to support efficacy sources. The control group only planned and taught mini-lessons and received brief and undetailed feedback. Results showed significant differences in participants' personal science teaching efficacy beliefs and student outcome expectancy beliefs in terms of the treatment group. The STEB scores of the control group also decreased at the end of the study. It is suggested that pre-service teachers should have the opportunity to reflect on their performances, artifacts, or lesson plans and to design them several times.
All-atomistic molecular dynamics study of the glass transition of amorphous polymers

Glass transition is an important phenomenon of polymer materials and it has been intensively studied over the past a few decades. However, the influencing factors arising from the chemical structures of the polymers are often ignored due to a continuous or coarse-grained description of the polymer. Here, we approached this phenomenon using all-atomistic molecular dynamics (MD) simulations and two conventionally used polymer materials, polycarbonate (PC) and poly-(methyl methacrylate) (PMMA). We reproduced the glass transition temperatures (Tg) of the two materials reasonably well. Then we characterized and investigated the glass transition process by looking at the changes of potential energy, dihedral transition, and thermal fluctuation of the individual degrees of freedom in the systems, over the entire temperature range of glass transition. As previously reported, the dihedral angles stop their conformational changes gradually at the Tg, especially for the main chain dihedrals, and sidechain rotations immediately rooting from the main chain. The volumetric change during the temperature decrease is confirmed to be because of conformational adjustment, probably due to the tendency of chain stretching for the maintenance of the radius of gyration, and the loss of thermal energy. The strength of motions of single degrees of freedom and polymer chains, and overall slow motions obtained by normal mode analysis (NMA) shows that different motions at different spatial scale may gradually stop at distinct temperature in the MD simulation temporal and spatial scales. Presumably, the small spatial scale do not contribute to the glass transition at the experimental scale since the timescale is much longer than their relaxation time.
First successful hybridization experiment between native European weatherfish (Misgurnus fossilis) and non-native Oriental weatherfish (M. anguillicaudatus) reveals no evidence for postzygotic barriers

The European weatherfish Misgurnus fossilis (Linnaeus, 1758) is a threatened freshwater species in large parts of Europe and might come under pressure from currently establishing exotic weatherfish species. Additional threats might arise if those species hybridize which has been questioned in previous research. Regarding the hybridization of M. fossilis × M. anguillicaudatus (Cantor, 1842), we demonstrate that despite the considerable genetic distance between parental species, the estimated long divergence time and different ploidy levels do not represent a postzygotic barrier for hybridization of the European and Oriental weatherfish. The paternal species can be easily differentiated based on external pigment patterns with hybrids showing intermediate patterns. No difference in standard metabolic rate, indicating a lack of hybrid vigour, renders predictions of potential threats to the European weatherfish from hybridization with the Oriental weatherfish difficult. Therefore, the genetic and physiological basis of invasiveness via hybridization remains elusive in Misgurnus species and requires further research. The existence of prezygotic reproductive isolation mechanisms and the fertility of F1 hybrids remains to be tested to predict the potential threats of globally invasive Oriental weatherfish species.
MICROMETEOROLOGICAL CHARACTERIZATION OF PROTECTED ENVIRONMENTS FOR PLANT PRODUCTION

This study evaluates the influence of the four seasons and twelve months of the year on the micrometeorological variables of global solar radiation, air temperature, and relative air humidity in different protected environments for plant production. The protected environment types and the characteristics of the shade screen modify the indoor air temperature. This environment provides greater relative humidity. The global solar radiation percentages in the environments were: full sun (100%); black screen with 30% shading (47.3%); greenhouse with LDPE + 22-30% shading screen under the film (38.1%); aluminized screen with 35% shading (36.9%) and greenhouse with LDPE + 42-50% shading screen under the film (26.9%). The micrometeorological conditions of environments such as air temperature, relative air humidity, and global solar radiation in the seasons of year are similar to the behavior verified in the monthly test. Air temperatures and global solar radiation formed two distinct groups, with the spring and summer seasons being considered one group and autumn and winter another group. The summer and autumn periods showed the highest relative humidity compared to the winter and spring periods, with a low percentage of air humidity. Seasons in the study region are not as well defined as those in the northern hemisphere.
Fertility of Roma Minorities in Central and Eastern Europe

We analyse Roma fertility in four neighbouring countries in Central and Eastern Europe with a large Roma minority: in Hungary, Slovakia, Romania and Serbia. The sources of data are the respective national population censuses from 2011. Fertility is measured at the birth cohort level as the average number of children ever born. We make an international comparison of the fertility of Roma and non-Roma majority population women on the basis of completed education. In the case of Hungary, we also explore how the correlation between fertility and ethnic identity is modified when completed education and ethnic residential segregation are controlled. The fertility of Roma women is far above the majority population average in all birth cohorts and in each country. Educational attainment modifies this relationship. The fertility of highly educated Roma and majority population women is converging. The exposure to majority behaviour also has an effect. The lower the level of ethnic residential segregation, the smaller the difference between the fertility of Roma and majority population women. Completed education and residential segregation may exert different forces at the two ends of the educational hierarchy when their joint effect is explored. At the upper end of the social hierarchy, neither segregation nor ethnicity matters; at the lower end, however, both exposure to ethnic majority behaviour and ethnicity matter.
Four-quadrant Characterization of Hydrodynamic Phenomena in a Low Specific Speed Centrifugal Pump

Objective: Identify and characterize subsynchronous hydrodynamics phenomena in a low specific speed centrifugal pump based on its four-quadrant characteristic curve. Materials: A 1.5 HP ITT Goulds pump instrumented with pressure transductors, an accelerometer, a torque sensor and a tachometer. Flow rate measurement was done with an ultrasonic transit time clamp-on flow meter. Methods: Time and frequency domain analysis with phase analysis were used to identify spectral components linked to hydrodynamic phenomena such as rotating stall and surge. Results and discussion: This work approaches an alternative method to calculate the phase angle using pressure signals without filtering. Related with hydrodynamic phenomena, the evidence collected suggests the presence of rotating stall in some operation points of the four-quadrant characteristic curve. Furthermore, in the third quadrant, rotating stall coexist with surge. Conclusions: The instrumentation and methods regarded in this work allow to collect evidence to identify in-phase and out of phase subsynchronous hydrodynamic phenomena. The classic cross-correlation-based method was improved to ease the diagnosis of subsynchronous phenomena by visual inspection. A new quantitative approach was introduced to detect subsynchronous phenomena, based on the Fourier analysis; it was validated with a case study for which the classical method was not suitable.
A mechanical model to determine upheaval buckling of buried submarine pipelines

Thermal loads in submarine pipelines generate an axial compressive load that can force the pipeline to buckle, leading to failure if these loads are not considered in the design. Buried pipes are constraint to displacements in all directions, which leads to a high compressive load in the longitudinal axis and makes the pipes more vulnerable to buckling. If buried pipes under thermal loads do not buckle, a high-stresses state takes place when it is combined with high-pressure conditions. In this work, a simple mechanical model to determine the axial buckling load of a buried pipeline is proposed. The model is based on a simply supported beam subjected to a distributed transverse load representing the soil uplift resistance obtained from a referenced model, and an axial compressive load that represents the effective axial force and is computed according to the DNV-RP-F110. Additionally, the pipe–soil system is analyzed through a non-linear finite element model to compare the results with the analytical solution. The proposed simple mechanical model can capture the upheaval buckling behavior and provides results that are consistent with the numerical analysis, specifically for the two main parameters evaluated, namely, the initial pipe curvature and the magnitude of the transverse load.
Evidence for and significance of the Late Cretaceous Asteroussia event in the Gondwanan Ios basement terranes

Abstract. The Late Cretaceous Asteroussia event as recorded in the Cyclades is a potential key to the tectonic evolution of Western Tethys. Microstructural analysis and 40Ar/39Ar geochronology on garnet–mica schists and the underlying granitoid basement terrane on the island of Ios demonstrates evidence of a Late Cretaceous high-pressure, medium-temperature (HP–MT) metamorphic event. This suggests that the Asteroussia crystalline nappe on Crete extended northward to include these Gondwanan tectonic slices. In this case, the northern part of the Asteroussia nappe (on Ios) is overlain by the terrane stack defined by the individual slices of the Cycladic Eclogite–Blueschist Unit, whereas in the south (in Crete) the Asteroussia slices are near the top of a nappe stack defined by the individual tectonic units of the external Hellenides. This geometry implies that accretion of the Ios basement terrane involved a significant leap of the subduction megathrust (250–300 km) southward. Accretion needs to have commenced at or about ∼38 Ma, when the already partially exhumed slices of the Cycladic Eclogite–Blueschist Unit began to thrust over the Ios basement. By ∼35–34 Ma, the subduction jump had been accomplished, and renewed rollback began the extreme extension that led to the exhumation of the Ios metamorphic core complex.

The total samples used in this study are 25 companies for each period. This study uses quantitative approach with multiple linear regression method. This study found that company sales growth, company risk, company profitability, and investment opportunity set simultaneous have significantly effect on dividend policy of Consumer Goods Industry Sector Companies since 2010 up to 2014. Partially, only investment opportunity does not affect significantly on dividend policy, and other sales growth, risk, profitability significantly affect on dividend policy. These results indicate that management should pay attention to sales growth, risk, and profitability to makes dividend policy.
Entry strategy in a nascent industry can shape how entrant firms compete and capture value. Considering heterogenous demand attributes across multiple emerging customer segments in a nascent industry

Faced with demand uncertainty and heterogeneity in a nascent industry, entrants often consider which customer segments to serve by tailoring the usage breadth and coherence of their product portfolios. Portfolio usage breadth is the extent to which products in a portfolio collectively span distinct customer segments, whereas portfolio coherence is the extent to which targeted customer segments of products in a portfolio overlap with each other’s customer segments. We suggest that when entrants have prior use experience in contexts that are potential users of the new product, their portfolios exhibit low usage breadth and high coherence, due to demand-oriented cognition and knowledge. The relationship is moderated by whether they are startups or diversifying entrants. The empirical context is the U.S. commercial drone industry.
