Does Immigration Affect Wages? A Meta-Analysis

Does immigration affect wages? No decisive answer has been provided until now. We propose an up-to-date meta-analysis of the literature investigating this question, based on 2,146 estimates from 64 studies published between 1972 and 2019. We find that, on average, the literature reports a negative and close to zero effect of immigration on native wages. This result holds for both low/medium-skilled and high-skilled native individuals. This average effect, however, hides a large heterogeneity across studies. Variation across estimates can be explained by the presence of structural heterogeneity such as the country of analysis or the use of micro-level data, as well as to heterogeneity in research designs such as the use of difference-in-differences. Finally, we estimate a significant and negative effect of publishing in leading academic journals and propose a discussion on the potential publication bias in the literature.
Examining Information Systems Infusion over the Routinization

Information systems (IS) infusion becomes important from the management perspective because organizations can leverage IS investment only at the IS infusion stage. The model for the stages of IS implementation explains that IS infusion can be achieved through IS routinization. This study examined how to achieve IS infusion through routinization based on application of the psychological empowerment theory and the unified theory of acceptance and use of technology (UTAUT), respectively. This study adds value to the IS literature by explaining how IS routinization leads to IS infusion and how their antecedents are different and related across the two stages. This study also provides guidance on how organizations can promote IS infusion beyond IS routinization, which then helps organizations leverage their IS investments.
Foreign listing pricing effects. The case of emerging economies

Together with global financial integration processes, companies from emerging markets gained access to foreign stock exchanges also through the issue of the depositary receipts. The aim of this paper is to examine the price reaction on the domestic stock exchange in response to cross-listing on foreign stock markets. To do so, we employ the event study method and investigate the pricing effects of 272 depositary receipts listings of companies from 12 emerging economies. Based on the non-parametric tests, we found that issuing depositary receipts generates statistically significant negative abnormal returns on the domestic stock market two days before the listing day. On the contrary, the results of the parametric test revealed negative but non-significant abnormal returns during the pre--listing period. We interpret our findings as evidence of non-positive market reaction and decreasing significance of the cross-listing decisions for the domestic shareholders.
PHENOLOGY, YIELD AND PROTEIN CONTENT OF MAIZE (Zea mays L.) HYBRIDS AS AFFECTED BY DIFFERENT SOWING DATES

The optimum sowing time and the suitable hybrid are agronomic management practices that play a major role in determining the quantity and quality of maize yield. In this study, a randomized field experiment was established at ARDS Simnic, Craiova to assess the influence of sowing dates and hybrids on phenology, grain yield and protein content of maize. The research included three sowing dates: 9 April, 16 April and 23 April. The results showed that the delayed sowing dates had higher impacts on the phenology of maize, shortened the all plant growing stages and reduced the accumulated heat units (GDD), especially after the silking stage. In early sowing date (9 April), the grain yield (GY) and heat use efficiency (HUE) were significantly higher compared to two other sowing dates, for all hybrids. Protein content of maize grain increased with delay in sowing date due to the modifications of thermal conditions during grain-filling period. Maize hybrids PR39D81 and LG3350 that produced the maximum grain yield (11.47 t/ha and 11.42 t/ha, respectively) when sown in 9 April, were the most suitable hybrids for this region.
A Non-dominated Sorting based Evolutionary Algorithm for Many-objective Optimization Problems

The optimization problems with more than three objectives are many-objective optimization problems (MaOPs) that exist in various scientific and engineering domains. The existing multi-objective evolutionary algorithms do not found effective to address the many-objective optimization problems. Its limitations initiated the need to develop an algorithm that efficiently solves many-objective optimization problems. The proposed work presents the design of the many-objective hybrid differential evolution algorithm (MaOHDE) to address MaOPs. Initially, two multi-objective evolutionary algorithms viz. non-dominated sorting based multi-objective differential evolution (NS-MODE) and non-dominated sorting based multi-objective particle swarm optimization (NS-MOPSO) algorithms designed. These algorithms developed by incorporating the non-dominated sorting approach from NSGA-II, the ranking approach, weight vector, and reference points. Tchebycheff – a decomposition-based approach applied to decompose the MaOPs. The MaOHDE algorithm developed by hybridizing the NS-MODE with the NS-MOPSO algorithm. The presented approach’s strength is revealed using 20 instances of DTLZ functions and its effectiveness and efficiency are verified by comparing with the recently developed state of algorithms from the literature. From the results, it is observed that the MaOHDE responds better than its competitors or is competitive for most of the test instances and the convergence rate is also good.
The Impact of Cross-Listing on Firms Capital Structure: Evidence from Brazil

This article investigates the effects of ADR issuance on indicators of Capital Structure and Cost of Capital. Secondary data was obtained from the Economática® database. Propositions were tested using Unobserved Effects Panel Data Model. For the years 2005 to 2011, 27 ADR-issuing companies were studied out of a sample of 227 companies. The results indicate that ADRissuing companies have on average 40% greater financial leverage, as well as an approximately 50% lower cost of capital, though the degree of significance is not as statistically favorable as the pre-established trends, which were less than the obtained results.
Factors Affecting Share Price of Nepalese Non-Life Insurance Companies

This study examines the factors affecting the share price of Nepalese non-life insurance companies. This study is based on secondary data of 15 non-life insurance companies with 105 observations for the period from the fiscal year 2011/12 to 2017/18. The result shows that firm size is positively related to market price of share and price earnings ratio. It indicates that larger firm size leads to increase in market price of share and price earnings ratio. However, the study shows that inflation is negatively related to market price of share and price earnings ratio. The study also shows that dividend per share and return on assets are negatively related to the market price of share and price earnings ratio. Similarly, earnings per share have negative relationship with market price of share and price earnings ratio. The study concludes that the increase in return on assets and earnings per shares do not explain the variation in stock price in Nepalese non-life insurance companies. Nepal is one of the emerging economy; the determinants identified will provide knowledge to the potential investors about the key factors affecting share prices in the country and accordingly assist them in optimizing their investment strategy. The knowledge of the factors and their possible impact on share prices is highly appreciable as it would help investors make wise investment decisions and enable firms to enhance their market value.

Investigation of antioxidant activity of protein hydrolysate derived from baby clam (Corbiculidae sp.) broth

This study is aimed to bring baby clam broth (BCB) into antioxidant proteolysate utilizing enzymatic hydrolysis. Chemical compositions of BCB were firstly analyzed, followed by investigating the effects of enzymatic hydrolysis parameters involving in enzyme type, pH, temperature, enzyme:substrate (E:S) ratio and hydrolysis time on antioxidant of BCB proteolysate. It can be seen from the result that the BCB owned the moisture content, protein content, lipid content, and ash content of 97.55±0.89%, 1.52±0.16%, 0.09±0.02%, and 0.37±0.04%, respectively. The BCB proteolysate, under the hydrolysis condition including Flavourzyme, pH 7, 50°C, E:S ratio of 5 U/g protein and hydrolysis time of 50 min, exhibited the highest 2,2'-Azino-bis(3-ethylbenzthiazoline-6-sulfonic acid) cation ratio (ABTS●+) scavenging activity of 770.67±28.33 µM Trolox Equivalent (µM TE) (7.1 and 2.5 times lower than those of vitamin C and butylated hydroxytoluene (BHT), in order) and ferric reducing antioxidant power (FRAP) value of 245.26±7.37 µM TE (11.6 and 4.0 folds lower than those of vitamin C and BHT, respectively). This study suggests a new use of the BCB, antioxidant proteolysate which could be applied as a functional food or natural antioxidant additive, substituting for synthetic compounds.
Syntactic satiation is driven by speaker-specific adaptation

Listeners adapt to variability in language use by updating their expectations over variants, often in speaker-specific ways. We propose that adaptation of this sort contributes to satiation, the phenomenon whereby the acceptability of unacceptable sentences increases after repeated exposure. We provide support for an adaptation account of satiation by showing that the satiation of purportedly unacceptable island-violating constructions demonstrates speakerspecificity, a key property of adaptation.
CORPORATE GOVERNANCE ATTRIBUTES AND SOCIAL SUSTAINABILITY REPORTING

The objective of this study is to examine the relationship between corporate governance and social sustainability reporting in quoted firms in Nigeria. The ex-post facto research design was used for this study. The data set was sourced from the annual reports of selected quoted companies on the Nigerian stock exchange. Out of a population of 176 quoted firms on the NSE as at December 31st, 2016, thirty five financial and non financial companies had complete and consistent data that was useful for this study. The balanced panel data regression technique was used in this study. The corporate governance attributes which are the independent variables were CEO tenure, executive compensation, Board gender diversity, Board size and firm size (as control variable). Correlation results show that there is a positive association between the dependent variable of social sustainability reporting and all the independent variables of interest except for the variable of executive compensation. The adjusted R2 of the probit panel random effect regression model is 0.34 which indicates that only 34% of the changes in the variable of social sustainability reporting is explained by the changes in the regressor. It was discovered that executive compensation and CEO tenure has no significant relationship with corporate social sustainability reporting. While Board gender diversity and board size had a significant relationship with corporate social responsibility reporting. It was recommended that the representation and participation of women on boards should be sustained and improved to promote social sustainability reporting for the firms and that quoted companies should keep up with the recommended board size in order to maintain a sizeable performance in terms of social sustainability reporting.
THE SOCIAL ENVIRONMENT CHANGE UNDER THE INFLUENCE OF ARTIFICIAL INTELLIGENCE THE VIEWS OF ORTHODOX CLERGY AND PARISHIONERS

The article examines the nature of changes in the social environment under the influence of artificial intelligence by revealing and analysing the views of Orthodox clergy and parishioners. It was characteristic that the opinions of most clergy and parishioners coincided in a negative attitude to the influence of artificial intelligence on the social environment. The high degree of dependence of social and cultural aspects of the development of society and human psyche on artificial intelligence causes anxiety and fear among clergy and parishioners. The essential negative influence of artificial intelligence on religious activity is revealed. The main advantage of this study is that the on-going social changes are evaluated from the point of view of representatives of the Orthodox faith, both clergy and parishioners. The revealed characteristic features and dependence can be used in the formation and development of the categorical-conceptual apparatus in the social and humanitarian scientific fields as the basis for the development and protection of existing values in the social sphere and religion.
Effect of Saline Water Irrigation and Growing Media on Growth, Physiological and Mineral Parameters of Clove Pink Dianthus Caryophyllus

Soil salinity is one of the major environmental factors limiting plant growth and development; and it is considered a problem in arid and semiarid regions, where rainfall is insufficient to leach salts. The clove pink, Dianthus caryophyllus L. is a major product in Jordan with different irrigation needs and has the capacity to cope with water deficit. Consequently, the current study aimed at investigating the effect of salinity on certain growth, physiological and mineral parameters of two varieties of D. caryophyllus (Bizet Sagr and Grand Slam Hygr). The experiments were conducted under greenhouse conditions at the University of Jordan during the 2015/2016 growing season. The plants were grown in either soil or zeolitic tuff at five salinity levels. The results indicated that the growth parameters of both D. caryophyllus varieties vary significantly among the different salinity levels in both growing media. Increasing salinity caused a significant reduction in plant height, fresh and dry weights, flower length and diameter, and a delayed flowering time. Increasing salinity level caused also a significant reduction in leaf greenness, fluorescence yield, and relative water content, and increased stomatal resistance of both plant varieties in both growing media. Increasing salinity level caused a significant increase in Na and Cl, and a decrease in K, P, and N concentrations in plants of both tested varieties and media. In conclusion, salinity caused a significant effect on all tested growth, physiological and mineral parameters of D. caryophyllus. An appropriate irrigation regime should be used as a key to success in ornamentals’ growth control.
THE EFFECT OF DIVERSIFICATION LEVEL, NUMBER OF SEGMENTS, AND INDUSTRY SECTOR TYPE ON COMPANY PERFORMANCE

The high competition in the business world with many competitors has forced the company to develop its business, one of them by diversification. This study aims to investigate the influence of diversification level, the number of segments, and type of industrial sector on firm performance measured by the excess value. The theory underlying this research is agency theory, which describes the relationship between the company owners with the company management. The number samples of this study are 333 companies from the miscellaneous industry sector, consumer goods sector, and basic industry and chemicals sector listed on the Indonesia Stock Exchange throughout 2017 – 2018. The results showed that data can be pooled for 3 years, all classic assumption tests are fulfilled, and partial regression coefficient test found that variable diversification level and the variable number of segments > 0.05, then H01 and H02 rejected, while the type of miscellaneous industry sector and type of consumer goods sector <0.05, then H03 and H04 received. The conclusion showed that variable diversification level and number of segments has not sufficient evidence of a negative effect on excess value, while the type of miscellaneous industry sector and type of consumer goods sector sufficient evidence of a negative effect on excess value.
Seroprevalence and risk factors of West Nile virus infection in veterinarians and horses in Northern Palestine

Background and Aim: West Nile fever (WNF) is a neurotropic, mosquito-borne disease affecting humans and domesticated animals, caused by a member of the genus Flavivirus. Over the last decades, this virus has been responsible for several cases of illness in humans and animals. The current epidemiological status of WNF in horses is insufficient, and in veterinarians, as an occupational hazard is unknown. This study aimed to investigate and determine the seroprevalence and risk factors for WNF in veterinarians and horses in Palestine. Materials and Methods: In this study, serum samples from 100 veterinarians and 87 horses were collected between August 2020 and September 2020 from different cities of Northern Palestine. West Nile virus (WNV) antibodies were detected using an enzyme-linked immunosorbent assay. Results: Our results showed that 60.9% of the horse serum samples were positive in all investigated cities. In horses, location is a risk factor for the seropositivity for WNF, whereas age, sex, breed, and intended use of the horses, were not associated with increased WNF seropositivity. In veterinarians, 23.0% of the serum samples were positive. Positive samples were detected in all locations, age groups, experience length, and work sectors. However, the seropositivity for WNF was not influenced by these variables. Conclusion: The results revealed that WNV circulates in most regions of Palestine. Our results will help determine the risk of infection in animals and humans and control WNV transmission. Surveillance studies on humans, vectors, and animals are needed to better define endemic areas.
Analysis of renal calcular disease among children: our tertiary care experience

Renal stone disease is an ailment that is very distressing and a matter of concern for most of the patients. The prevalence of the disease has been reported as 1-15% worldwide. Over the last few years, the prevalence of the disease in children has risen. In some countries, such as the Middle East and Southeast Asian ones, urolithiasis is endemic. With renal calculus in 2% to 3% of the paediatric population, India is included in the 'stone belt. The stone itself is not a disease, but it can be one of the indications of other systemic diseases. For thisreason, children presenting early with first stone event should undergo rigorous early and detailed medical ABSTRACT
Real Earnings Management versus Accrual-based and Its Effect on Firm Performance: Evidence from Egypt

This paper empirically investigates whether Egyptian firms use real activities manipulation to substitute accrual-based earnings management, and what is the effect of real earnings management on operating performance for a sample of firms listed on the Egyptian Stock Exchange during the period from 2000 through 2014. Results demonstrate that: First, Egyptian firms employ both accrual-based and real earnings management to achieve earnings targets. The two mechanisms are used simultaneously, no complete substitutive relation between the two strategies. Second, Egyptian managers do not alter their earnings management techniques to cope with corporate and political events. This is evident in the passive response for the introduction of Egyptian Accounting Standards in 2007 and the Egyptian Revolution of 2011. Third, real activities manipulation has an adverse effect on Egyptian firms' performance, where real earnings management metrics are negatively associated with firms' just meeting earnings benchmarks.
A simple method to estimate entropy of atmospheric gases from their action

A convenient model for estimating the total entropy ({\Sigma}Si) of atmospheric gases based on physical action is proposed. This realistic approach is fully consistent with statistical mechanics, but uses the properties of translational, rotational and vibrational action to partition the entropy. When all sources of action are computed as appropriate non-linear functions, the total input of thermal energy ({\Sigma}SiT) required to sustain a chemical system at specific temperatures (T) and pressures (p) can be estimated, yielding results in close agreement with published experimental third law values. Thermodynamic properties of gases including enthalpy, Gibbs energy and Helmholtz energy can be easily calculated from simple molecular and physical properties. We propose that these values for entropy are employed both chemically for reactions and physically for computing atmospheric profiles, the latter based on steady state heat flow equilibrating thermodynamics with gravity. We also predict that this application of action thermodynamics may soon provide superior understanding of reaction rate theory, morphogenesis and emergent or self-organising properties of many natural or evolving systems.
Pressurized Oxy-fuel Combustion: A Study of Selected Parameters

Oxy-fuel combustion is a potential low-emission technique for energy conversion. This paper presents the results of oxy-fuel experiments under high-pressure conditions. The influence of process parameters, such as reactor pressure and temperature, on the emission of NOx, N2O, and other compounds was tested. A new oxy-fuel experimental setup is presented. The experiments were conducted using a laboratory-scale (fuel input of up to 3 kg/h) pressurized fluidized-bed combustor. The feedstock used was “Ziemowit” coal, and the tests were carried out under oxy-fuel and air-fired conditions. The temperature inside the reactor was in the range of 750–900 °C. Generally, NOx emission decreases significantly under higher pressure; however, the details of this trend depend upon the experimental conditions. The effects of pressure and temperature on NOx and N2O emissions are discussed.
