Analisis Jumlah Uang Beredar, Inflasi dan Nilai Aktiva Bersih Reksadana Syariah

Abstract: Nett asset value (NAV) is a barometer of the performance of sharia mutual funds. The increase in NAV shows that the performance of sharia reksadana is good, and vice versa. Several factors can affect the NAV of Islamic mutual funds, including the money supply and inflation. This study aims to answer the proposed hypothesis that there is a significant effect of the money supply and inflation on the net asset value of sharia mutual funds. The method used is a quantitative method with time-series data. The population in this study is data on the amount of money supply, inflation, and net asset value of sharia mutual funds in Indonesia. The sample is 60 data from January 2015 to December 2019. To process and analyze the data, researchers conducted multiple linear regression tests using the software SPSS 24. It is known that simultaneously the money supply and inflation have a significant effect on the net asset value of Islamic mutual funds. The money supply also has a substantial impact on the net asset value of Islamic mutual funds. However, inflation does not have a significant effect on the net asset value of Islamic mutual funds.
Functional Properties of Fruits of Common Medlar (Mespilus germanica L.) Extract

Common medlar (Mespilus germanica L.) is a long-lived plant with hard fruits, which are harvested in the fall and stored in cold and dark places. The aim of the work was to obtain the extract from freeze-dried fruits of medlar. Then, the samples were purified on a column with Amberlite XAD-16 ion exchange resin (two fractions were obtained and tested in further steps: methanol (MF) and water (WF)). A quantitative analysis of the polyphenolic compounds and selected elements was performed. In addition, in vitro tests of antidiabetic and antioxidant activity of the extracts were carried out. The applied methodology included the determination of antidiabetic activity by diffusion method, antioxidant activity by ABTS and FRAP methods, elemental analysisby atomic spectrometry, and quantitative and qualitative determination of phenolic composition by UPLC method. The highest antioxidant activity was observed in the MF of the medlar preparation, which was 245.31 μM Trolox/g (in ABTS test). Both fractions showed positive antidiabetic effects. For WF, even a small concentration of 1 mg/mL DMSO, the percentage of α-amylase inhibition was 35%. The WF dominated in terms of the total content of phenolic compounds (mainly gallic, procatechic, chlorogenic, and ferulic acids).
Predicting Failure on the Sex Offense Registry: An Examination of Static and Dynamic Factors

Abstract There is considerable research on the efficacy of sex offense registries, but less is known about individual compliance with registration. Recent research and subsequent policy have highlighted the importance of understanding technical violations as a hidden driver of mass incarceration, and there is emerging evidence that suggests that agency violation practices vary widely. We analyzed administrative data from a large sample of individuals on the sex offense registry in Missouri to identify the factors associated with risk for noncompliance, including a technical violation and reincarceration. Both stable and dynamic factors contribute to our understanding of compliance and incarceration. Findings also suggest that living in a county with few registrants contributes to lowered odds of noncompliance. Alternatively, high caseloads contribute to greater odds of incarceration only. More generally, we find a sizeable portion of jurisdictional variation remains for both noncompliance and incarceration, a finding that suggests different enforcement practices across place.
Augmentation of low frequency damping via hydrogen-doping in a hybrid shape memory alloy composite

Carbon fiber reinforced polymer (CFRP) composites hybridized with hydrogen-doped NiTi wires can be used to design structures requiring high stiffness and high damping in the low frequency range, such as helicopter blades. The current work investigates aging and hydrogen-doping for high damping without hydrogen embrittlement. We establish a hydrogenation treatment that (i) results in a response that is repeatable in the martensitic phase and after exposure to composite processing temperatures and (ii) increases the loss factor in NiTi wires by nearly 470%. By embedding H-doped wires exhibiting the highest damping into the interlayers of a [0/±45]s carbon/epoxy laminate at a volume fraction of 0.1, the hybrid NiTi-CFRP composite loss factor increases by 170%. The measured dynamic properties were found to be close to micromechanical predictions based on the properties of the NiTi and CFRP.
The Arbitrage Lobby: Theory and Evidence on Dual Exchange Rates

Abstract Foundational theories of trade politics emphasize a conflict between consumer welfare and protectionist lobbies. But these theories ignore other powerful lobbies that also shape trade policy. We propose a theory of trade distortion arising from conflict between consumer welfare and importer lobbies. We estimate the key parameter of the model—the government's weight on welfare—using original data from Venezuela, where Hugo Chávez used an exchange-rate subsidy to underwrite hundreds of billions of dollars of imports. Whereas estimates from traditional models would make Chávez look like a welfare maximizer, our results indicate that he implemented distortionary commercial policy to the benefit of special interests. Our analysis underscores the importance of tailoring workhorse models to account for differences in interest group configuration. The politics of trade policy is not reducible to the politics of protectionism.
The Protective Impacts of α-tocopherol Supplementation on the Semen Quality of Sapera Goat Preserved at 4oC

Supplementation of vitamin E (α-tocopherol) as an antioxidant into an extender is useful to maintain sperm quality during the process of cryopreservation by protecting the sperms from reactive oxygen species (ROS). This study aims to evaluate the protective impacts of vitamin E supplementation on the motility, viability, and reducing the abnormality of sperms in Sapera goats. The sample of semen used in the present study was obtained from fresh semen and good-quality ejaculates of the Sapera goats collected by an artificial vagina. The groups involve one controlled treatment group, which contains semen and tris egg yolk (TEY) extender without vitamin E (P0), and three treatment groups that contain semen, TEY extender, and different doses of vitamin E, i.e., 1 mg/mL (P1), 2 mg/mL (P2), and 3 mg/mL (P3), respectively. Data obtained from the experiments were analyzed using Repeated Measures Multivariate Analysis (MANOVA). The results showed that TEY extenders added with vitamin E at a dose of 1 mg/mL of vitamin E (P1) produced the highest motility and viability with the lowest abnormalities of sperm after 24th hour of cryopreservation. The lowest sperm motility and viability among the treatment groups was observed in the TEY extender added with vitamin E at a dose of 3 mg/mL (P3) at 96th hour after cryopreservation, which was almost the same as the control group without vitamin E (P0) that had the lowest motility and viability. In conclusion, the current study found that supplementation of vitamin E as an antioxidant at a dose of 1 mg/mL in TEY extender can preserve semen of the Sapera goats in refrigerator up to 96 h at 4°C and provides higher sperm motility and viability percentage, with a lower percentage of sperm abnormality.
Origin of anomalous band-gap bowing in two-dimensional tin-lead mixed perovskite alloys

The origin of the pronounced and composition-dependent band-gap bowing in Sn/Pb mixed perovskite alloys has been under debate for a long time. Previous studies reported conflicting results on whether the chemical or structural effect is the dominant mechanism. In this paper, the band-gap bowing effect and its possible origins in recently synthesized two-dimensional (2D) ${\mathrm{Cs}}_{2}{\mathrm{Pb}}_{x}{\mathrm{Sn}}_{1\text{\ensuremath{-}}x}{\mathrm{I}}_{2}{\mathrm{Cl}}_{2}$ alloys are investigated from first-principles calculations. In agreement with experiments, a large and composition-dependent bowing coefficient is observed. By analyzing the contribution from volume deformation, charge exchange, structural relaxation, and short-range order, it is found that the dominant mechanism causing the anomalous gap bowing is the structural relaxation-induced wave-function localization, forming isovalent-defect-like states, despite the negligible octahedral distortion and small lattice mismatch between the two end compounds. This is understood by the s-p repulsion-induced strong antibonding character of the valence-band maximum which leads to a large deformation potential, thus even a small atomic displacement can result in a large shift of the energy level. These results thus highlight the critical role of strong deformation potential and structural relaxation effect in unusual band evolution of 2D Sn/Pb perovskite alloys, and can be helpful to the modulation of their band gap for optoelectronic applications.
Protest Demobilization In Post-Revolutionary Settings: Trajectories To Counter-Revolution And To Democratic Transition

This article examines two outcomes of demobilization in post-revolutionary contexts, democratic transition and counter-revolution. Complementing elite-driven approaches, we argue that the way demobilization ends is conditional upon the capacity of challengers to promote enduring alliances. Following a paired controlled comparison, we analyse two cases, Egypt and Tunisia and processes of alliance building and fragmentation preceding the 2013 coup d’Etat in Egypt, and the adoption of a new Constitution in 2014 in Tunisia. Data from semi-structured and in-depth interviews were collected through fieldwork in multiple localities of Egypt and Tunisia between 2011 and 2019. Results show that the fragmentation of the challengers’ coalition in post-revolutionary Egypt contributed to a counter-revolution while, in Tunisia, challengers’ alliances rooted in the pre-revolutionary period lasted throughout the phase of demobilization and supported a democratic transition. We conclude by discussing some alliance-based mechanisms accounting for a democratic transition: intergroup trust-building, brokerage and ideological boundary deactivation.
Drained behaviour of artificially cemented dune aeolian sand

ABSTRACT Mixing cement and soil is a traditional technique used to improve their mechanical properties. Other studies proposed a rational dosage methodology for soil-cement mixtures. This method is based on the void-cement ratio and aimed at obtaining a particular strength level. The present study evaluated the validity of the void-cement ratio (η/Civ) and analysed the stress – strain – strength behaviour of aeolian dune sand from Natal, Brazil, mixed with cement. Isotropically consolidated drained triaxial compression tests (CID-C) were conducted with moulded samples containing 0.0, 2.5, 5.0 and 7.5% cement by weight of dry soil. Void ratios corresponded to three conditions of relative density: loose, medium and dense, with confining stresses of 50, 100, 200 and 300 kPa. The effect of void ratio, cement content and void-cement ratio on the stress-strain-strength behaviour of the mixtures was determined. The results showed that the void-cement ratio is an appropriate parameter to assess the effective strength of the cement-sand mixture studied.
The tradition of classroom deliberation and the evasion of racial justice as a social issue, 1916–1966

ABSTRACT In this historical study, the author traces the contents of classroom materials and methods textbooks published between 1916 and 1966 that endorsed the discussion and deliberation of social issues to demonstrate how these materials consistently evaded racial justice as a social issue. As a result, the materials designed to inspire classroom discussion and deliberation of social issues ended up reinforcing the racial status quo through an approach that valued balance and open-ended discussion of racial issues over a commitment to racial justice and the affirmation of Black perspectives.
Regulation of Follicular Atresia by WIP1-Mediated Apoptosis and Autophagy

Female endocrine homeostasis and reproductive success depend on the number and quality of follicles. The follicle is the basic functional unit within mammalian ovaries. Excessive follicular atresia is responsible for the accelerated ovarian aging process. Therefore, exploring the molecular mechanism of follicle development and atresia is essential for protecting ovarian function. In this study, we interrogate the striking correlation between follicular atresia and wild-type p53-induced phosphatase 1 (WIP1) expression in mouse ovaries to understand how WIP1 phosphatase activity regulates follicle development. WIP1 is mainly expressed in granulosa cells of healthy growing follicles, and atretic follicles exhibit significantly weaker WIP1 expression compared with the healthy ones. Our in vivo study indicates that inhibition of WIP1 phosphatase activity causes endocrine disorder, fertility decline and decreased ovarian reserve by triggering excessive follicular atresia through promoting autophagy and apoptosis. By in vitro follicle culture, we determine that inhibiting the WIP1 activity impairs the follicle development, causing more follicular atresia and decreased oocyte quality. Besides, downregulating WIP1 expression in granulosa cells in vitro also promotes apoptosis and autophagy via WIP1-p53 and WIP1-mTOR signal pathway. Our findings from the in vitro and in vivo experiments revealed that appropriate Wip1 expression is required for follicle development. Downregulation of WIP1 expression accelerates follicle atresia via WIP1-p53 and WIP1-mTOR signal pathway related apoptosis and autophagy. It is speculated that moderate up-regulation of WIP1 expression may help delaying the decline of ovarian reserve.
Distributionally robust portfolio maximization and marginal utility pricing in one period financial markets

We consider the optimal investment and marginal utility pricing problem of a risk averse agent and quantify their exposure to model uncertainty. Specifically, we compute explicitly the first‐order sensitivity of their value function, optimal investment policy and Davis' option prices to model uncertainty. To achieve this, we capture model uncertainty by replacing the baseline model P with an adverse choice from a small Wasserstein ball around P in the space of probability measures. Our sensitivities are thus fully non‐parametric. We show that the results entangle the baseline model specification and the agent's risk attitudes. The sensitivities can behave in a non‐monotone way as a function of the baseline model's Sharpe's ratio, the relative weighting of assets in the agent's portfolio can change and marginal prices can both increase or decrease when the agent faces model uncertainty.
Adsorption Behavior of Cationic Dye on Bentonite Functionalized With 3-aminopropyltriethoxysilane

The current study focused on the modification of Algerian bentonite clay (Bent) with the product of hydrolysis of 3-aminopropyltriethoxysilane (APTES) using the intercalation process. The modified clay (Bent-APTES) was investigated as an adsorbent solid for methylene blue dye (MB) removal from wastewater.The Bent-APTES was characterized by X-ray diffraction (XRD), chemical analyses, Fourier-transform infrared spectroscopy (FTIR) and thermogravimetric analysis (TGA). The cationic exchange capacity was also determined. Several adsorption parameters were evaluated on the adsorption performance. The results showed that the equilibrium adsorption data was found to fit better to the Langmuir adsorption model, and the adsorption capacity for the removal of MB on Bent-APTES was 217.39 mg g-1. The kinetic process of adsorption could be described by the pseudo-second order model. Consequently, the modified clay could be served as an efficient adsorbent for cationic dyes in wastewater treatment.
The Framing Territorial Demands (FraTerr) dataset: A novel approach to conceptualizing and measuring regionalist actors’ territorial strategies

ABSTRACT This article introduces a new dataset on regionalist actors’ territorial demands and frames in Europe. The FraTerr dataset advances on existing datasets by proposing a more fine-grained understanding of regionalist actors’ territorial demands, and is the first to provide comparative data on how these are framed. Methodologically, it develops an original coding scheme for the qualitative content analysis of political documents. Empirically, this approach is applied to a comparative study of regionalist parties and civil society actors in twelve European regions. A preliminary analysis of the data provides new evidence of the complexity of regionalist actors’ territorial demands and the multi-dimensional nature of their framing strategies. The dataset has implications for the study of regionalist actors and issues, and for broader scholarly efforts at estimating political actors’ territorial issue positions and framing strategies.
Rock Fragments in Shallow Lunar Regolith: Constraints by the Lunar Penetrating Radar Onboard the Chang'E‐4 Mission

It is generally believed that the top centimeters of mature lunar regolith should be dominated by fine particles that contain few rocky fragments, but surface fragments are occasionally visible in mature lunar regolith. Based on amplitudes of surface echoes received by the Lunar Penetrating Radar onboard the Yutu‐2 rover of the Chang'E‐4 mission, we extracted regions with abnormally high relative permittivity that is larger than 4, quantifying the abundance of dense fragments within the top ∼4 cm of the mature regolith along the rover path. We carried out high‐resolution numerical simulations for the propagation of electromagnetic waves, showing that the abnormally high relative permittivity is not caused by local topography but due to the existence of dense materials. Using high‐resolution images obtained by the panorama camera onboard the rover, we performed correlated observation for areas with abnormally high relative permittivity, confirming that some of these dense materials are exposed rocky fragments. However, most of the high relative permittivity areas are not correlated with surface fragments, and some are located beneath floors of highly degraded small impact craters. We found that regolith clumps formed due to impact compaction are not dense enough to cause the abnormally large relative permittivity. Alternatively, the detected dense materials may be melt‐bearing impact breccias in the shallow regolith, which were formed by the host craters. The results revealed a highly heterogeneous structure at shallow depths of mature lunar regolith, revealing a new mechanism of sand‐blasting impacts on the destruction of pores in mature lunar regolith.
Solar wind magnetic holes can cross the bow shock and enter the magnetosheath

Abstract. Solar wind magnetic holes are localized depressions of the magnetic field strength, on timescales of seconds to minutes. We use Cluster multipoint measurements to identify 26 magnetic holes which are observed just upstream of the bow shock and, a short time later, downstream in the magnetosheath, thus showing that they can penetrate the bow shock and enter the magnetosheath. For two magnetic holes, we show that the relation between upstream and downstream properties of the magnetic holes are well described by the MHD (magnetohydrodynamic) Rankine–Hugoniot (RH) jump conditions. We also present a small statistical investigation of the correlation between upstream and downstream observations of some properties of the magnetic holes. The temporal scale size and magnetic field rotation across the magnetic holes are very similar for the upstream and downstream observations, while the depth of the magnetic holes varies more. The results are consistent with the interpretation that magnetic holes in Earth's and Mercury's magnetosheath are of solar wind origin, as has previously been suggested. Since the solar wind magnetic holes can enter the magnetosheath, they may also interact with the magnetopause, representing a new type of localized solar wind–magnetosphere interaction.
Realisation of overflow oscillation-free fixed-point digital filters with 2’s complement arithmetic

ABSTRACT In this paper, we focus on the problem of overflow oscillation elimination in 2’s complement state variable realisation of fixed-point digital filters. A new global asymptotic stability (GAS) criterion for the zero-input fixed-point state-space digital filters employing 2’s complement overflow arithmetic is proposed. The proposed criterion captures the structural properties of 2’s complement overflow nonlinearities in a greater detail as compared to several existing criteria. A comparative evaluation of the proposed criterion with various previously reported criteria is made. The obtained criterion turns out to be less stringent than several existing results. An example along with simulation results to substantiate the utility of the criterion is also provided.
Tests of Equal Forecasting Accuracy for Nested Models with Estimated CCE Factors*

Abstract In this article, we propose new tests of equal predictive ability between nested models when factor-augmented regressions are used to forecast. In contrast to the previous literature, the unknown factors are not estimated by principal components but by the common correlated effects (CCE) approach, which employs cross-sectional averages of blocks of variables. This makes for easy interpretation of the estimated factors, and the resulting tests are easy to implement and they account for the block structure of the data. Assuming that the number of averages is larger than the true number of factors, we establish the limiting distributions of the new tests as the number of time periods and the number of variables within each block jointly go to infinity. The main finding is that the limiting distributions do not depend on the number of factors but only on the number of averages, which is known. The important practical implication of this finding is that one does not need to estimate the number of factors consistently in order to apply our tests.
Optimizing the role of youth cadre through education about the impact of drug abuse on adolescents

Adolescents are a very vulnerable age at risk of drug abuse. Through the empowerment of youth Posyandu (health center) cadres in education about the impact of drug abuse, it is expected to be one of the promotive and preventive efforts so that teenagers are not entangled in drug abuse. This community service program aimed to provide socialization to youth Posyandu cadres about the dangers of drug abuse. This activity was attended by 40 participants who had previously taken the Covid-19 screening test to ensure this activity was safe to do at the Sumurjomblangbogo Village Hall, Pekalongan. Pretest and Posttest were conducted to measure the knowledge of cadres before and after being given education. The results of this community service, can increase the knowledge of cadres from the majority of good knowledge (70%) to very good (90%). Similar activities are needed to develop youth Posyandu cadres to have health maintenance skills. Of course, it takes support and participation from residents and village officials.
