THE CURRENT STAR FORMATION RATE OF K+A GALAXIES

We derive the stacked 1.4 GHz flux from FIRST (Faint Images of t he Radio Sky at Twenty Centimeters) survey for 811 K+A galaxies selected from the SDSS DR7. For th ese objects we find a mean flux density of 56±9 μJy. A similar stack of radio-quiet white dwarfs yields an upp er limit of 43μJy at a 5σ significance to the flux in blank regions of the sky. This implies an average star f ormation rate of 1.6± 0.3 M⊙ year for K+A galaxies. However the majority of the signal comes from ∼4% of K+A fields that have aperture fluxes above the5σ noise level of the FIRST survey. A stack of the remaining gala xies shows little residual flux consistent with an upper limit on star formation of 1.3 M ⊙ year. Even for a subset of 456 ‘young’ (spectral ages < 250 Myr) K+A galaxies we find that the stacked 1.4 GHz flux is consis tent with no current star formation. Our data suggest that the original starburst has been terminate d in he majority of K+A galaxies, but that this may represent part of a duty cycle where a fraction of these galax ies may be active at a given moment with dusty starbursts and AGNs being present.

Parental Cross-Nativity and Intermarriage among Second-Generation Mexican Americans in Metropolitan Los Angeles

Sociologists have long regarded intermarriage as an important indicator of integration between immigrant and native groups. This study examines how parental cross-nativity marriages between Mexican-origin foreign-born parents and Mexican-origin parents born in the U.S. affect intermarriage among second-generation Mexican Americans in metropolitan Los Angeles. Logistic regression analysis provides the likelihood of intermarriage with the NonHispanic white majority group (the group with which the Mexican-origin population intermarries the most) based on data from the Immigration and Intergenerational Mobility in Metropolitan Los Angeles (IIMMLA) survey. This research shows that second-generation Mexican Americans who have a foreign-born mother and a U.S. native-born father are more likely to intermarry with non-Hispanic whites compared to second-generation Mexican Americans whose parents are both foreign-born. The daughters of foreign-born mothers and native-born fathers demonstrate the highest likelihood of intermarriage. Foreign-born mothers who are arguably less traditional and more tied to the new country, demonstrated by marriage to a native-born coethnic, may socialize their daughters to pursue non-traditional gender roles by encouraging them to achieve more education, thus leading to a higher likelihood of intermarriage integration. Although parental cross-nativity leads to intermarriage integration for some second-generation Mexican Americans, there is also evidence that they experience racialized integration, demonstrated by a high endogamy rate.
Profit Taxation, R&D Spending, and Innovation

IZA DP No. 14830 NOVEMBER 2021 Profit Taxation, R&D Spending, and Innovation* We study how profit taxation affects plants’ R&D spending and innovation activities. Relying on geocoded survey panel data which approximately covers the universe of R&Dactive plants in Germany, we exploit around 7,300 changes in the municipal business tax rate over the period 1987–2013 for identification. Applying event study models, we find a negative and statistically significant effect of an increase in profit taxation on plants’ R&D spending with an implied long-run elasticity of −1.25. Reductions in R&D are particularly strong among more credit-constrained plants. In contrast, homogeneity of effects across the plant size distribution questions policy makers common practice to link targeted R&D tax incentives to plant size. We further find lagged negative effects on the (citationweighted) number of filed patents. JEL Classification: H25, H32, O31, O32
Impact of Covid-19 on the Stock Market and Corporate Firms in India

Covid-19 was declared by WHO as a ‘pandemic’ on March 11, 2020, and the very next day the Indian stock market crashed heavily. This was primarily due to net outflows of foreign institutional investment (FII). While most of the sectors would go through adverse experience due to Covid-19, there are sectors where the negative impact could be low due to low negative demand shock or a strong balance sheet of firms. In this paper, we highlight the possible consequences of the pandemic. We contend that the direction of sector-wise movement in FII flow signals which sectors will grow or shrink in the coming years. Analysing the daily data from March 2, 2020 to May 22, 2020, we observe that FII flow ‘Granger causes’ stock market performance, measured by the closing price. We also observe from the analysis of Impulse Response Functions that the effect of external shock on FII has destabilizing impact on the closing price of BSE Sensex till the next 10 days. Higher profitability in the past years, better growth opportunities in the stock market and being a stand-alone firm have a favourable impact on stock price reactions to COVID-19 shocks and hence they make the firms with these characteristics more resilient. We also discuss the possibility of ‘herding’ by the foreign institutional investors following the current volatility in the stock market. Arbitrage activity, especially short selling by arbitrageurs, is also likely to increase, which may further destabilize the stock market. In India, as stocks experienced sharp falls in the wake of the Covid-19 outbreak, SEBI imposed a ban on short selling since March 23 in an attempt to stabilise the market and maintain investor confidence. However, the effectiveness of the ban on short-selling remains a contested issue. 1 Professor, Institute of Development Studies Kolkata, e-mail:indrani.c61@gmail.com 1
Democracy and Diversion: Government Arrangements, the Economy, and Dispute Initiation

Do legislative constraints constrain or compel democratic executives’ conflict behavior during periods of economic decline? Although institutional constraints are thought to reduce democratic executives’ propensity to engage in interstate conflict, other research suggests that such constraints may provide incentives to engage in diversionary uses of force. Incorporating work from the comparative study of economic voting and cross-national research on the diversionary use of force, this article contends that government arrangements — coalition, minority, weak party cohesion — influence democratic conflict behavior by (1) shaping the extent to which the executive is held accountable for the economy and (2) determining the executive’s capacity to address the economy with legislation. Specifically, the argument presented here suggests that governing parties in coalition governments share the blame for a poor economy, reducing the likelihood that the executive initiates disputes in response to the economy. Compared to single-party majority governments with high party discipline, executives presiding over minority governments, or whose parties are plagued by a lack of cohesion, are more likely to initiate disputes when faced with poor economic conditions, because these executives are likely to face resistance to remedial economic policy. Probit analyses of the interactive effects of government arrangements and economic performance on dispute initiation among industrialized democracies, 1950—97, support the argument. The article concludes with implications for research in comparative politics and international relations, including, for example, executive—legislative relations and strategic conflict avoidance.
Recommendations for implementation of physical training guidelines for patients undergoing chronic hemodialysis

The exponential growth in the prevalence of chronic kidney disease (CKD) is currently one of the greatest public health challenges worldwide, with a high economic impact at the health level and on the quality of life of affected patients. In countries with a low organ donation rate, hemodialysis is the renal replacement treatment par excellence. Although hemodialysis improves patient survival, in the medium and long term it generates a series of consequences and pathophysiological adaptations that gradually cause a significant reduction in general physical function, affecting daily activities and quality of life. The evidence of the beneficial effects of exercise in patients with any stage of chronic kidney disease, including those on dialysis therapy, is well known. Different types of physical training programs have shown to significantly improve the physical function of patients. The positive impact on clinical aspects such as mental health, hemodialysis efficacy as well as associated healthcare costs is significant. In Latin American countries, these programs are still at a very incipient level of development. The present work is a review of recommendations that should be considered for the implementation of a physical training program for patients on chronic hemodialysis.
Electromagnetic vibration and noise assessment for surface mounted PM machines

Analysis of electromagnetic vibration and acoustic noise assessment and methods to minimize resultant sound power level for low noise motor design is presented in this paper. The linear model of the exciting force wave is derived to evaluate the exciting force and to optimize the design of stator winding, rotor PM shape and rotor PM skew angle for minimization of sound power level for low noise motor design. Mode number and frequency of the exciting force wave, natural vibration frequency, maximum vibration velocity and maximum vibration displacement of main vibration source are introduced to evaluate machine vibration. Resultant sound power levels for the cylindrical sound wave and the plane sound wave models are introduced to analyze the acoustic noise assessment of both axial and radial flux PM machines respectively. Finally, electromagnetic vibration and acoustic noise assessment of both radial and axial flux surface mounted motor structures are completed and illustrated in the paper.
Predictive autoregressive models using macroeconomic variables: the role of oil prices in the Russian stock market

Article history: Received: February 27, 2021 Received in revised format: April 29 2021 Accepted: May 21, 2021 Available online: May 25, 2021 This article evaluates the relationship of macroeconomic variables of the domestic market with the stock index on the Moscow exchange and selects forecast specifications based on an integrated autoregressive model the moving average. The methods used are included in an integrated autoregressive-moving average model with exogenous variables and seasonal component, Box and Jenkins approach, auto.arima in R function, Hyndman and Athanasopoulos approach, and maximum likelihood method. The results demonstrate that the inclusion of external regressors in the onedimensional ARIMAX model improves its predictive characteristics. Time series of macro-indicators of the domestic market – the consumer price index, the index of output of goods and services for basic activities are not interrelated with the index of the Moscow exchange, with the exception of the dollar exchange rate. The positive correlation between the Moscow exchange index and macro indicators of the world economy the S&P stock index, the price of Brent oil, was confirmed. In models with minimal AIC, a rare presence of the MA component was found, which shows that the prevailing dependence of the stock market yield on previous values of the yield (AR component) and thus, better predictability of the yield. It has shown that for stock market forecasting, "manual" selection of the ARIMA model type can give better results (minimum AIC and minimum RMSE) than the built-in auto.arima algorithm in R. It is shown that from a practical point of view, when selecting forecast models, the RMSE criterion is more useful for investors, which measures the standard error of the forecast in points of the stock index. For the scientific novelty, using Russian financial data for the period from March 2000 to March 2018 to measure the connection of macro indicators of domestic and global markets with the Moscow exchange stock index, considering seasonality can be noticed. The comparison of the forecast model’s accuracy of the ARIMA type obtained by automatic and "manual “selection by AIC and RMSE is performed in favor of "manual" selection. It could be noted that the main conclusions of the article can be used in scientific and practical activities in the stock markets as a practical significance. © 2021 by the authors; licensee Growing Science, Canada
Construction industry in China's regional economy, 19901998

Construction has been perceived as a pillar industry in China's economic revitalization. Policies and programmes have been implemented by the central and local governments to promote the development of the national and local construction industries, in the hope of driving the growth of the economy. Developments in China's economy and in particular, in different regions, can be used to test the hypotheses on the relationship between construction and economic development. This paper examines the geographical distribution of construction in the provinces of China, and the relationship between construction and regional economic growth. It also studies different types of projects, ownership patterns, and levels of technology applied. The study provides useful insights into the relationships between the construction industry, and the economy and development especially at the regional level.
GEOGRAPHIC VARIATION IN STEM-XYLEM TERPENE CHEMISTRY IN NATIVE POPULATIONS OF PZNUS

Oleoresin samples were collected from 170 individual trees of Pinus greggii from 9 native populations located throughout the species' natural distribution in Mexico. The samples were analyzed for chemical composition using gas chromatography and G C mass spectrometry. The species in general had high proportions of 8-phellandrene and low proportions of a-pinene. The northern populations studied were distinct from southern populations in having lower proportions of a-pinene and myrcene, and higher proportions of limonene and longifolene. Genetic variation in relation to four of the monoterpenes studied was greater in southern populations than in northern populations. Genes affecting the production of the five terpenes studied appeared to be fixed in the northern populations, but only two terpenes tended toward fixation in southern populations.
Application of Fuzzy Logic Controller to Enhance The Semi-SWATH Performance in Following Seas

Semi-SWATH ship has a different characteristics compared to the common ship hull. The ship has a tendency to suffer bow-dive due to low restoring force at bow when running in following seas. In some conditions, the foredeck found to be immersed under the rear of wave. Acceleration motion to the trough increases the momentum force that pushing the ship to dive. The condition may cause the ship has a loss of control even the crew can feel thrown forward. In this research, fin stabilizer was applied to reduce the effect of those conditions with application of fuzzy logic controller. The controller calculates the angle for the fin stabilizer based on the pitch angle. The fin at both ends of the ship’s hull increase the lift force, reduce the trim angle, and restrain the ship from dynamic high acceleration. A numeric time-domain program developed to analyze the ship seakeeping in following sea. The results showed the controller ofthe fin stabilizer has a significant effect in preventing the ship from the unsafe condition.
HOW DO EXPECTATIONS SHAPE CONSUMER SATISFACTION? AN EMPIRICAL STUDY ON KNOWLEDGE PRODUCTS

This study aims to gain a better understanding of how the expectation-confirmation process shapes consumers’ satisfaction with products in the emerging online knowledge industry. Like other experience products, the benefits that a consumer can gain from a knowledge product are greatly associated with the consumer’s initial expectations. To capture consumers’ attitudes towards knowledge products both before and after usage, this study conducts an innovative online survey in order to explore both the direct and indirect effects of pre-usage expectations on consumers’ satisfaction. Four hundred valid responses were collected, and the proposed hypotheses were empirically verified through structural equation modeling. The results indicate that both direct and indirect paths of expectation positively impact satisfaction, although the latter has a stronger influence. In addition, product price positively moderates the relationship between expectation and confirmation. The findings extend expectation-confirmation theory by introducing perceived risk and product price as constructs, and they contribute to the literature by providing empirical evidence of the effect of pre-usage expectations on consumers’ satisfaction. This study can help knowledge product providers and third-party platforms better understand how consumer satisfaction forms and, subsequently, enhance long-term customer relationships.
Chronology and Controls

Quantitative satellite observations only provide an assessment of ice sheet mass loss over the last four decades. To assess long-term drivers of ice sheet change, geological records are needed. Here we present the first millennial-scale reconstruction of David Glacier, the largest East Antarctic outlet glacier in Victoria Land. To reconstruct changes in ice thickness, we use surface exposure ages of glacial erratics deposited on nunataks adjacent to fast flowing sections of David Glacier. We then use numerical modelling experiments to determine the drivers of glacial thinning. 5 Thinning profiles derived from 45 10Be and 3He surface exposure ages show David Glacier experienced rapid thinning of up to 2 m/yr during the mid-Holocene (∼6.5 ka). Thinning stabilised :::::: slowed at 6 ka, suggesting the initial formation of the Drygalski Ice Tongue at this time.

An experimental investigation on workload limiting methods within ORR policies in a job shop environment

The performances of three workload limiting policies are analysed, and the following are the three objectives: (i) assessing whether the method of workload limiting affects the performances of Order Review and Release strategies; (ii) investigating the performances of the workload limiting methods when the mix imbalance changes; (iii) evaluating the robustness of the workload limiting methods considered. The methodological pattern followed required a simulation model of a dynamic job shop system and all the workload limiting methods are tested by resorting to a fractional factorial experimental design with repetitions. Results coming from simulation campaign show that the 'upper bound only' method is the best performer. Furthermore three different mix imbalance levels have been tested, showing that 'workload balancing' method allows closer performances to those of the 'upper bound only'. Finally 'workload balancing' is proven to be the most robust, but not all the results are statistically significant for all performance indexes.
Gross Deposit Flows

This paper examines aggregate deposit inflows, outflows, and the reallocation of deposits in the banking system to further our understanding of banking stability. I find that on average deposit inflows are nearly three times larger and twice more volatile than outflows. Deposit flows vary with business cycles and market conditions, across deposit types, and cross-sectionally. Moreover, there is considerable heterogeneity in flows across deposit types. I also find that the largest banks attract and retain more deposits compared to smaller banks, and deposits are reallocated from small to largest banks. Deposits are also reallocated to banks which offer higher deposit rates, have lower insolvency risk assets, and low capital levels. My findings imply that deposit inflows and the heterogeneity in depositors are important in understanding banking stability. Moreover, at the aggregate level deposits are reallocated to banks that provide more utility to depositors, suggesting some evidence of market discipline. JEL Classification: G21, G32
ISLAMIC LEADERSHIP PRINCIPLES AND ACCOUNTABILITY OF ISLAMIC INSURANCE INSTITUTIONS: A PLS PATH MODELLING APPROACH

This paper reports the findings of the questionnaire survey which aims to examine the effect of Islamic leadership principles on accountability practices of Islamic insurance institutions in Malaysia. A total of 227 employees responded to the survey, were attached with Islamic insurance operators located throughout Peninsular Malaysia. Five principles were derived from the literature namely; altruism, emotional healing, wisdom, persuasive mapping, and organizational stewardship. Partial least squares approach was employed as the main analytical procedures to test the research hypotheses. The results of the study indicate that all five principles are significantly related to the level of accountability among Islamic insurance institutions. The findings of this study suggest that for an Islamic insurance institution to demonstrate high level of accountability, the leader needs to exhibit principles of altruism, emotional healing, wisdom, persuasive mapping, and organizational stewardship. In addition, this study provides implications and conclusion.
Multivariate control charts for process dispersion

The multivariate extension of control charts for process dispersion is not as straightforward as that for the process mean. A general model and techniques that would encompass a wide range of problems encountered in practice is not available. In most cases, particular problems need to be handled in a specific manner. In this paper we consider several special cases of a process displacement affecting the covariance matrix and we develop control charts (both Shewhart-type and CUSUM) to detect these process changes.
EFFECT OF USING ORGANIC FERTILIZERS ON LETTUCE TYPE ʻLOLLO ROSSOʼ UNDER OUTDOOR METEOROLOGICAL CONDITIONS

This paper presents the results of an experiment related to cultivation of red-leaf lettuce type ‘Lollo rosso’ variety ʻTuskaʼ outdoors, in transition to organic production. The experiment has been conducted in field conditions on the premises of the Agricultural University in the region of Plovdiv. During the lettuce growth several variants were tested: 1. NPK (mineral fertilization); 2. Control (non-fertilization); 3. Italpollina; 4. Arkobaleno; 5. LC (Lumbricompost); and 6. Ekoprop NX. The effect of the different organic fertilizers has been studied through the main biometrical parameters. Statistically significant differences have been reported for the most important indicators fresh mass weight g and number of leaves with highest values observed in variants 6. Ekoprop NX and 4. Arkobaleno. Organic fertilization successfully replaces the fertilization with a combined fertilizer (NPK) under the different hydrothermal conditions of the experimental period.
