The Influence of Sheltering or Protective, Parental Behaviors Following Child Trauma; Hurricane Katrina

s This study examined the relationship between parental behaviors and trauma experienced by 42 school-aged children (6 to 12 years of age) impacted by a natural disaster; Hurricane Katrina. Results showed that one of the parental behaviors examined, open communication, was positively associated with higher Post-traumatic Stress Disorder Reaction Index scores in the child population. This finding indicates that open communication from parent-to-child may increase trauma symptoms in school-aged children following a traumatic event. Results of this research may contribute to mental health intervention practices following child trauma, and disaster related prevention planning. The influence of parental behaviors following child exposure to trauma may be of particular importance to mental health practitioners, emergency management agencies and emergency and disaster relief workers.
Asteroseismology from the main sequence to giant stars

The thesis focuses on the use of asteroseismology to probe the structure of stellar sources. By observing pulsational variability, a detailed description of the interior of stars, and the determination of stellar parameters can be obtained. An extensive sample of bright K and M class giant stars were surveyed to detect the presence of any noticeable variability. Three giant stars have been studied in detail. In Arcturus (alpha Boo), no oscillations at a significant amplitude were detected. In beta UMi (Kochab) multiperiodic oscillations have been observed for the first time, allowing an asteroseismic estimate for the mass. In gamma Crucis (Gacrux) previously observed frequencies have been confirmed, and the modes shown to be sinusoidal in nature. Two main-sequence stars have been studied in detail. In the first, gamma Dor, prototype star of the class of gamma Doradus variable stars, three oscillations further to those previously known were unambiguously detected in the star. In the second, nu Eri, a beta Cephei class variable star, modes detected by an extensive previous campaign were confirmed, with determined frequencies in excellent agreement between the two studies. All results gathered should provide a valuable input to future models of these stars, and provide an interesting starting point for further, detailed studies.
Epidemic Trends Analysis and Risk Estimation of 2019-ncov Outbreak

Since December 8, 2019, the spread of COVID-19 is increasing every day. It is particularly important to predict the trend of the epidemic for the timely adjustment of the economy and industries. We performed the trends of 2019-nCoV (COVID-19) in China based on Flow-SEHIR model. The results show that the basic reproductive numbers R0 of COVID-19 is 3.56 (95% CI: 2.31 - 4.81). The number of daily confirmed new cases reaches the inflection point on Feb. 6 - 10 outside Hubei. For the maximum of infected cases number, the predicted peak value in China except Hubei was estimated to be 13806 (95% CI: 11926 - 15845). The peak arrival time is on March 3 - 9. The peak cumulative number of patients in Hubei was estimated to be 63800 (95% CI: 59300 - 76500). The temporal number of patients in most areas of China outside Hubei will peak from March 12 to March 15. The peak values of more than 73.5% provinces or regions in China will be controlled within 1000.
Preventing Stillbirth: A Review of Screening and Prevention Strategies

Abstract Stillbirth is a devastating pregnancy complication that still affects many women, particularly from low and middle-income countries. It is often labeled as “unexplained” and therefore unpreventable, despite the knowledge that placental dysfunction has been identified as a leading cause of antepartum stillbirth. Currently, screening for pregnancies at high-risk for placental dysfunction relies on checklists of maternal risk factors and serial measurement of symphyseal-fundal height to identify small for gestational age fetuses. More recently, the first-trimester combined screening algorithm developed by the Fetal Medicine Foundation has emerged as a better tool to predict and prevent early-onset placental dysfunction and its main outcomes of preterm preeclampsia, fetal growth restriction and stillbirth by the appropriate use of Aspirin therapy, serial growth scans and induction of labour from 40 weeks for women identified at high-risk by such screening. There is currently no equivalent to predict and prevent late-onset placental dysfunction, although algorithms combining an ultrasound-based estimation of fetal weight, assessment of maternal and fetal Doppler indices, and maternal serum biomarkers show promise as emerging new screening tools to optimize pregnancy monitoring and timing of delivery to prevent stillbirth. In this review we discuss the strategies to predict and prevent stillbirths based on first-trimester screening as well as fetal growth and wellbeing assessment in the second and third trimesters.
Magnetic properties of amorphous Fe90-xMnxZr10(0≤x≤12) alloys

The magnetization as a function of field and temperature has been measured for a series of amorphous Fe 9 0 - x Mn x Zr 1 0 alloys with x=0-12 in the temperature range 4.2-300 K. All the samples of the present study show double transition (reentrant) behavior below room temperature. The high-temperature transition (T c ) decreases linearly at about 6 K/at. % of Mn, while the low-temperature transition (T s g ) increases at about 2.6 K/at. % of Mn. A detailed analysis of the temperature dependence of magnetization data reveals: (i) Spin-wave excitations at low-temperature, single-particle excitations and local-spin-density fluctuations (LSDF's) over a wide range of intermediate temperatures and enhanced fluctuations in the local magnetization for temperature close to T c contribute dominantly to the thermal demagnetization of spontaneous magnetizations; (ii) external applied magnetic field of strength ≥5 kOe suppresses the LSDF's; (iii) the spin-wave stiffness constant (D) decreases from 35.6′0.3 to 23.2′0.2 meV A 2 with increasing Mn concentration; and (iv) the D/T c ratio remains constant for all the compositions. A study of critical behavior of the magnetic order-disorder transition by various methods suggest that the critical exponents obtained below and above Curie temperature obey a scaling law [δ-1=γ/β and α+γ=2(1-β)] with a high degree of accuracy in the asymptotic critical region. The exponents are independent of composition and are in close agreement with the values those predicted for three-dimensional Heisenberg ferromagnets. The magnetic parameters such as high-field susceptibility, coercivity, local magnetic anisotropy, and spin-glass behavior, obtained from the low-temperature magnetization data, are consistent with the presence of a mixed magnetic state. The detailed analysis of high-field thermomagnetization data could be explained in terms of the nearest-neighbor Heisenberg model. Moreover, the temperature dependence of the magnetic behavior is discussed in terms of competing ferromagnetic and antiferromagnetic exchange interactions.
Towards an Antarctic meteorite hotspot map

Information: Dr. Stef Lhermitte (s.lhermitte@tudelft.nl) Dr. Harry Zekollari (h.zekollari@tudelft.nl) Background Meteorites are left-overs from the formation of the solar system, and as such, they contain priceless information about the chemical composition of the solar system as it was being born. The Antarctic Ice Sheet is the most prolific region for collecting meteorites on Earth. Most meteorites are collected in blue ice areas, which can act as meteorite hotspots. In these hotspots, meteorites are transported to the surface through ice flow, where they can remain for several hundreds to thousands of years. So far, the collection of meteorites in Antarctica has mainly focused on a few dedicated sites, which have typically been identified by chance (i.e. by encountering meteorites when exploring this region).
University of Birmingham p-p, p-, and - correlations studied via femtoscopy in pp reactions at s = 7\ TeV

We report on the ﬁrst femtoscopic measurement of baryon pairs, such as p - p , p - (cid:2) , and (cid:2) - (cid:2) , measured by ALICE at the Large Hadron Collider (LHC) in proton-proton collisions at √ s = 7 TeV. This study demonstrates the feasibility of such measurements in pp collisions at ultrarelativistic energies. The femtoscopy method is employed to constrain the hyperon-nucleon and hyperon-hyperon interactions, which are still rather poorly understood. A new method to evaluate the inﬂuence of residual correlations induced by the decays of resonances and experimental impurities is hereby presented. The p - p , p - (cid:2) , and (cid:2) - (cid:2) correlation functions were ﬁtted simultaneously with the help of a new tool developed speciﬁcally for the femtoscopy analysis in small colliding systems: Correlation Analysis Tool using the Schrödinger equation (CATS). Within the assumption that in pp collisions the three particle pairs originate from a common source, its radius is found to be equal to r 0 = 1 . 125 ± 0 . 018 (stat) + 0 . 058 − 0 . 035 (syst) fm. The sensitivity of the measured p - (cid:2) correlation is tested against different scattering parameters, which are deﬁned by the interaction among the two particles, but the statistics is not sufﬁcient yet to discriminate among different models. The measurement of the (cid:2) - (cid:2) correlation function constrains the phase space spanned by the effective range and scattering length of the strong interaction. Discrepancies between the measured scattering parameters and the resulting correlation functions at LHC and RHIC energies are discussed in the context of various models.
IMPACT OF DISAGGREGATED PUBLIC EXPENDITURE ON INFLATION RATE IN SELECTED AFRICAN COUNTRIES: A PANEL COINTEGRATION ANALYSIS 1

ABSTRACT: The study examined the long run association between disaggregated public expenditure and inflation rate in selected African countries with data spanning 1990-2019. The study employed a panel cointegration technique and estimated the cointegrating relationship using the Fully Modified OLS (FMOLS), and Dynamic OLS (DOLS) proposed and advanced by Pedroni (1996, 2001) and Kao and Chiang (2001). The findings from the cointegration result reveal the existence of a long run equilibrium relationship among the variables. Also, the panel dynamic OLS revealed that a 1percent change in infrastructure (capital) and defense expenditures leads to about 0.56 percent and 0.27 percent incremental change in inflation rate respectively. On the other hand, expenditure on education has a positive and an insignificant relationship with inflation, while expenditure on health has an inverse but insignificant influence on inflation rate in the region within the period under study. The study recommends that public expenditure on infrastructure in the selected African countries be appropriately channeled to stimulate investment and production, thereby stabilizing prices.
SAVINGS MOBILIZATION ON POVERTY ALLEVIATION AMONG PERI-URBAN FARMING HOUSEHOLDS IN KWALI AND BWARI AREA COUNCILS F.C.T ABUJA, NIGERIA

: Savings is increasingly being acknowledged as a powerful tool for poverty alleviation but the peri- urban households who are mostly, low cadre workers, peasant farmers and small-scale business owners lacks savings services. This study analyzed savings mobilization on poverty alleviation among peri-urban households in Kwali and Bwari Area Councils Abuja. Cross-sectional primary data was used in this study. The data was collected with the aid of a well-structured questionnaire administered to 185 peri-urban farming households. Descriptive statistics (mean, frequency and percentage), Foster Greer Thorbecke index and ordered logit regression were used to analyze the collected data. The results that emanated from the analysis reveals that 98% of respondents are within the economic active age while 82% of them had formal education and average household size of 4 person. About 93% of households saved in one form or the other. About 51% of the respondent are non-poor while 49% are poor based on analysis of poverty status which revealed poverty incidence of 49%, poverty depth of 28% and poverty severity of 56%. The results further reveals that primary occupation and education reduces the likelihood of not being poor, but there is an increment in the likelihood of being very poor while farm size, savings, access to credit and income generated from secondary activities increases the probability of being non-poor, but reduces the probability of being very poor. Therefore, households should be encouraged by Governmental agencies to engage in secondary economic activities for multiple stream of income to improve on their poverty status. In addition, government should facilitate the establishment of Financial Institutions in the Peri- Urban areas to inculcate saving habit among the people.
Corporate Social Responsibility (CSR) and Financial Performance of Kompas100 Entities for the year 2015-2019

This paper examines the relationship between Corporate Social Responsibility (CSR) and Corporate Financial Performance (CFP) in Indonesian firms listed under Kompas100 index. ESG rating is the independent variable and represents the CSR performance of firms. The dependent variables of this study are ROA, ROE, and Net Profit Margin, representing firms' financial performance. The findings show no significant relationship between CSR and CFP under various regression specifications. Nevertheless, firm profitability is affected by firm size, firm risk, sales growth, liquidity, and leverage. These results are in line with prior studies by Aupperle et al. (1985) and Mc Guire et al. (1988), where no significance exists between CSR performance and financial performance. Upon samples of Indonesian firms, a study by Hermawan and Mulyawan (2014) is in line with the result of this study in the sense that there is no correlation between CSR and profitability of Indonesian firms. The underlying reason is that there are still challenges in analyzing CSR's direct impact on firms' profitability, not only for Indonesian firms. CSR is not generalizable as it differs across countries. Based on further research, CSR practices implemented by Indonesian firms are not motivated by profit considerations, but the achievement of smooth business operations. To conclude, this study shows that the profitability of firms in Indonesia is not affected by CSR practices.
Cell Stimulatory Potential Dendritic Cells Without Affecting Their T Production by In Vitro-Generated Human Glucocorticoids Inhibit Bioactive IL-12p70

Glucocorticoids (GC) are known to affect the immune response at several stages. However, little is known about how GC inﬂuence the initiation of the speciﬁc immune response at the level of dendritic cells (DC), the highly professional APC for T cells. Therefore, we studied whether GC modulate the cytokine production and T cell stimulatory function of DC. In LPS-stimulated DC, GC strongly reduced the secretion of the Th1-skewing factor IL-12p70 and, to a lesser extent, the production of the proinﬂammatory cytokines IL-6 and TNF- a . Regarding the T cell stimulatory function of DC, GC did not inﬂuence the cell surface expression of HLA-DR or the costimulatory molecules CD40 and CD80 and did not inﬂuence the ability of DC to take up Ag. Consequently, GC pretreatment of DC indeed did not affect their ability to stimulate CD4 1 Th cell proliferation in response to superantigen. However, as a result of their defective production of bioactive IL-12, GC-pretreated DC have a reduced ability to promote the production of IFN- g in CD4 1 Th lymphocytes, as shown by the observation that IFN- g production could be restored by exogenous IL-12. In contrast, GC treatment of DC enhanced the secretion of the antiinﬂammatory cytokine IL-10 and the type 2 cytokine IL-5 by the T cells. It is concluded that, in addition to their role as potent inhibitors of inﬂammation via the direct suppression of cytokine production in T cells, GC may further inhibit T cell-mediated inﬂammation indirectly via the suppression of IL-12 production by DC.

Towards a Carbon-Neutral Environment, the Role of Biomass Energy Consumption and Trade Openness in Sub-Saharan Africa: A Spatial Econometric Analysis

Energy consumption is known as the catalyst for economic growth, however, the association of CO 2 emissions with energy consumption has prompted policymakers to pursue types of energy that ensure sustainable development. This paper analyses the spillover effect of CO 2 emissions and the marginal effect of Biomass energy consumption on CO 2 emissions in Sub-Saharan Africa by applying the extended Stochastic Impacts by Regression on Population, Affluence, and Technology (STIRPAT) model together with the spatial econometric models. The likelihood ratio test and Wald test indicated that the Spatial Durbin Model was the most suitable model to explain the elasticities of the exogenous variables. Furthermore, the Hausman test performed revealed that the fixed-effects model was more adept than the random-effects model. The findings suggested that increasing biomass energy consumption in a local country turns to reduce the country’s own CO 2 emissions and also reduces the CO 2 emissions of its adjacent countries by 0.089% and 0.022% respectively . Whereas an increment in trade openness in a country pollutes its environment and that of its neighboring states by 0.163 % and 0.035% respectively. Comparing the indirect effect of the employed exogenous variables, foreign direct investment exerted a heavier weight impact than the others. Overall the study spotlighted some policies suggestions for the Sub-Saharan Africa states’ energy market in the cause of controlling the emissions of CO 2 .
Age dependent changes in synaptic NMDA receptor composition in adult human cortical neurons. 2

25 The molecular composition of glutamatergic synapses can determine integrative and plastic 26 properties of neurons. Studies in cerebral cortex and hippocampus of rodents have shown that 27 the subunit composition of synaptic N-methyl-D-aspartate receptors (NMDARs) undergoes a shift 28 from GluN2B to GluN2A rich synapses during development. Moreover, with ageing there is further 29 reduction of synaptic GluN2B and this is associated with cognitive decline. Whether NMDARs show 30 similar age-dependent changes associated with synaptic GluN2B loss in humans is unknown. We 31 investigated the contribution of GluN2A and GluN2B containing NMDARs in adult human neurons 32 using fresh non-pathological temporal cortical tissue resected during neurosurgical procedures in 33 subjects aged 21-70 years old. The tissue we obtained fulfilled quality criteria in the absence of 34 inflammation markers and proteomic degradation. We show an age-dependent decline in the 35 NMDA/AMPA receptor ratio in human temporal cortical synapses. We demonstrate that GluN2B 36 containing NMDA receptors contribute to synaptic responses in the adult human brain with a 37 reduced contribution in older individuals. With previous evidence for a causal role of synaptic 38 GluN2B in regulating synaptic strength and memory storage in mice, our results suggest important 39 implications for synaptic GluN2B in age-related cognitive decline. 40
BUSINESS CYCLE DRIVERS IN NIGERIA: SOME INSIGHTS FROM AN ESTIMATED DSGE MODEL

This paper develops a two-agent New Keynesian model, which is suitable for identifying the drivers of business cycle fluctuations in small open, resource-rich, resource-dependent emerging economies. We confront the model with Nigerian data on eleven macro-economic variables using the Bayesian likelihood approach and show that output fluctuations are driven mainly by oil and monetary policy shocks in the short run and domestic supply shocks in the medium term. On the other hand, monetary and domestic supply shocks jointly account for around 70 percent of short run variations in headline and core measures of inflation while oil shocks play a less prominent role owing partly to the low pass-through effect arising from the extant fuel subsidy regime in the country. Interrogating these findings further, we find that negative oil price shocks generate a persistent negative impact on output and a short-lived positive effect on headline inflation. In terms of policy responses, the estimated Taylor rule indicates a hawkish monetary policy stance over the sample period while the estimated fiscal rule provides evidence for a pro-cyclical and rather muted fiscal policy. Since domestic supply and oil-related shocks are key sources of macroeconomic fluctuations, the study calls for a more creative use of the country’s stabilisation funds as well as strategic fiscal interventions aimed at addressing the issues of domestic supply constraints and promoting private sector investments.
An Empirical Study Of Consumption Values On Green Purchase Intention

: Recently a major boost up in consumers converting to green consumption has been observed due to accelerating sustainable development. Subsequently, the purpose of this study is to analyze the influence of consumption values on green purchase intentions with the mediating role of green trust that has remained unexplored and unversed in emerging economies like Pakistan. This study attempts to discuss the theory of consumption and evaluates the relationship between consumption values, green trust, green image, and purchase intentions. A quantitative research method was used. A questionnaire was used to survey 400 consumers to collect information. This study applied the structural equation model (SEM) using Smart PLS. The research reveals that emotional, functional, and social and price values have a significant impact on green trust and witnessed that green trust and green image are essential mediators between consumption values (emotional, price, function, and social) and green purchase intentions. Hence, this study implies that organizations must retain their green trust by making efforts to maintain consumption values that eventually would help organizations to leverage green purchase intentions.
Effect of sodium compounds additives on the strength of cement-stabilized soils

Chemical stabilisation using cement is a common method of improving the weak properties of soft soils. This study presents the results of experimental tests on the effects of three sodium additive solutions, sodium hydroxide (NaOH), sodium carbonate (Na 2 CO 3 ) and sodium chloride (NaCl), on the strength of clayey (CS) and non-plastic/low plasticity property (NPS) soil-cement mixtures. Both soils condition, CS and NPS, represent the predominant soils in Mosul city, Iraq. The physical properties of these natural soils were obtained. X-ray diffractometry (XRD), X-ray fluorescence spectrometry (XRFS), and mercury intrusion porosimetry (MIP) tests were performed to further examine the microstructural characteristics of the soil samples. Furthermore, various concentrations of sodium additive solutions (0.5, 1, 1.5, 2, 2.5 and 3% by dry soil weight) were added to the soils to study the effect of these solutions on the unconfined compressive strength (UCS), California bearing ratio (CBR), and swelling potential characteristics of the soils. Variables such as cement content, curing period and concentration of chemical additives were considered. The results show an increase in the UCS of soil-cement mixtures corresponding to the incremental increases in the cement content and curing period of the samples. Also, the addition of NaOH and Na 2 CO 3 increased the strength of soil-cement mixtures, with a limited effect in the case of NaCl addition. The results indicate that 1% and 1.5% of sodium additives were optimal additive contents for maximal UCS and CBR values, respectively. The results also confirm the decreased swelling potential of CS-cement mixtures with the addition of sodium additives and demonstrates the superiority of NaOH over Na 2 CO 3 as an additive for soil stabilization.
