Associations between Microaggression and Adjustment Outcomes: A Meta-Analytic and Narrative Review
Authors: Lui P. Priscilla , Quezada Lucia
Published: September 2018

Microaggression has been considered a form of stressor that negatively affects people with marginalized statuses. Research shows variability in how microaggression is measured, and the extent to which it is associated with adjustment outcomes. A new cube model was proposed to conceptualize microaggression across social groups, interpersonal and group-level interactions, and categories of incidents. Synthesizing findings from published and unpublished studies, this study was aimed to examine the relations between microaggression and adjustment outcomes. Meta-analyses quantified the study-level correlations between microaggression and various adjustment outcomes, and estimated the degree to which methodological and individual factors explained between-study variability. Using 72 independent study samples (N = 18,718), omnibus analysis with a random-effects model showed a statistically significant summary correlation between microaggression and adjustment outcomes (r = .20, 95% CI = .16-.23, p < .001). Between-study variability (Q = 319.86, p < .001, 2 = .01, I2 = 77.80%) was explained by gender, race, and publication status. Except for gender microaggression, racial, LGBTQ, and health status microaggressions were associated with adjustment outcomes. Microaggression was relatively more strongly associated with internalizing problems, stress/negative affect, and positive affect/adjustment than with externalizing problems and physical symptoms. Adjustment outcomes were more closely linked to interpersonal microaggression than group microaggression, and to microassault than microinsult and microinvalidation. Narrative reviews showed that very few studies tested whether microaggression predicted adjustment outcomes above and beyond overt discrimination and individual difference factors, and examined the indirect mechanisms that may link microaggression to adjustment outcomes. Limitations to the scope of this research synthesis and future research directions are discussed.

Adaptation-like effects in body weight attractiveness are not simply norm based
Authors: Boothroyd Lynda , Pollet Thomas Victor , Evans Elizabeth , Yi Qu , Tovee Martin
Published: September 2018

Perceptions of body weight attractiveness can be manipulated through visual exposure to bodies at one weight extreme. This implies that body weight is coded relative to a central ‘norm’ or prototype. Cross-cultural research, however, shows differences between groups’ perceptions of body weight attractiveness in terms of preferences for specific weight ranges as well as overall differences in the perceived ‘ideal’ weight. Here we test for the first time whether visual exposure to body weight extremes can induce such localised changes in preferences within individuals. British and Chinese participants in Studies 1 and 3 rated 23 bodies of known BMI for attractiveness, before and after viewing underweight or overweight/obese bodies. Results of Study 1 and a combined analysis of Studies 1 and 3 together showed no evidence of significant changes in participants’ ‘ideal’ weight, but the groups which viewed obese bodies during adaptation rated bodies of BMI 30kg/m2 significantly more positively at post-test than those who had viewed underweight bodies. In Study 2, participants viewed 48 bodies of known BMI in a randomised order. Proportion of obese bodies viewed in the preceding 10 trials predicted more positive ratings of overweight/obese bodies, but not any other weight category. Together, these data strongly suggest that we can induce ‘local’ changes in body ideals through exposure but do not support a strict norm-based approach.
Perceptual proxies for extracting averages in data visualizations
Authors: Yuan Lei , Haroz Steve , Franconeri Steven
Published: September 2018

Across science, education, and business, we process and communicate data visually. One bedrock finding in data visualization research is a hierarchy of precision for perceptual encodings of data, e.g., that encoding data with Cartesian positions allows more precise comparisons than encoding with sizes. But his hierarchy has only been tested for single value comparisons, under the assumption that those lessons would extrapolate to multi-value comparisons. We show that when comparing averages across multiple data points, even for pairs of data points, these differences vanish. Viewers instead compare values using surprisingly primitive perceptual cues, e.g., the summed area of bars in a bar graph. These results highlight a critical need to study a broader constellation of visual cues that mediate the patterns that we can see in data, across visualization types and tasks.
Off to Market: Neighborhood and Individual Employment Barriers for Women in 21st Century American Cities
Authors: Haney Timothy
Published: September 2018

This paper endeavors to create a better understanding of the barriers to employment faced by disadvantaged urban women in the post-welfare reform era. Using data from the Project on Devolution and Urban Change, a unique geographically-linked, longitudinal, multi-city set of survey data, logistic regression models weigh the relative importance of individual barriers to employment (poor health, childcare and family responsibilities, etc.) and contextual or neighborhood barriers to employment (poverty rate, joblessness rate, etc.) on labor market outcomes. Results reveal that several neighborhood characteristics are predictive of employment, including automobile access, female-headedness, vacancy, and disorder. Results suggest a more complex, nuanced interplay between neighborhood-level variables and individually-measured variables in preventing some women from obtaining both modestly paying employment with few allocated hours of work per week, and also better-paying jobs with more hours of work per week.
The Experiential Gap in Disaster Research: Feminist Epistemology and the Contribution of Local Affected Researchers
Authors: Barber Kristen , Haney Timothy
Published: September 2018

In this article, we make the case for a situated knowledge of disasters. By applying a feminist standpoint framework, we argue that an ethic of “objectivity” and a privileging of the unattached researcher creates an experiential gap in the disaster literature whereby researchers who themselves experience disaster are undervalued and underrepresented. We analyze reflexive accounts by disaster researchers to show what epistemological barriers emerge from conventional processes of inquiry and the systematic disadvantaging of local, affected researchers. We also study patterns in articles by “outsider” and “insider” researchers, focusing on differences and similarities in research questions, reflexivity, relationships with and access to participants, and larger theoretical goals. This comparison reveals that the unique position of affected researchers can help to bridge formal knowledge and practical life knowledge, creating new and worthwhile paths to understanding the social effects of disaster.
Income Inequality in the European Union & United States: A Comparative Decomposition
Authors: Filauro Stefano , Parolin Zachary
Published: September 2018

This study applies improved household income data to measure and decompose trends in pan-European income inequality from 2006 to 2014. To contrast the relative significance of economic homogeneity versus the efficacy of welfare state and labor market institutions in shaping income distributions, we compare the structure of inequality in the EU-28 to that of the 50 United States. This comparison stands in contrast to the standard practice of evaluating the US against individual EU Member States. Despite the greater relative heterogeneity of the 28 EU Member States and our corrections for the underreporting of household income in the US, post-fisc income inequality in the EU-28 remains lower than that of the US from 2006 onward. Moreover, inequality appears to be rising in the US while it has remained stagnant since 2008 in the EU-28. In both unions, and particularly the US, within-state income differences contribute more to union-wide inequality than between-state differences. In a counterfactual analysis, we find that if the EU-28 matched the between-state homogeneity of the US, but maintained its relative within-country inequalities, pan-European inequality would fall by only 20 percent. Conversely, inequality in the US would fall by 34 percent if it matched the within-country inequality of the EU-28. Our findings suggest that the strengthening of egalitarian institutions within the 28 Member States is more consequential than economic convergence in reducing pan-European income inequality. We highlight institutional challenges toward achieving a ‘more equal’ Europe and discuss implications for future EU policymaking.
The Development of Children Pronunciation
Authors: Murni Sri Minda , Solin Mutsyuhito
Published: September 2018

Every child has a unique way of acquiring a language on his way to communicate with people around them. Some children find his way easily to ‘a good and appropriate pronunciation’ while other children ‘create’ his own and unique way. Understanding the pattern of unique or ‘false’ pronunciation can help parents understand their children’s language and be able to respond them appropriately. The study is aimed at describing the pattern of a baby boy’s pronunciation named Ghazi. Ghazi is 2.7 years old. He is mostly taken care by his mom who is a housewife and Dad who likes to spend his time feeding him. Ghazi is a healthy and energetic kid, surrounded by books for children to read and cartoons from youtube to watch. His favorite toy is hot wheels and show a big interest in animals. He has travelled across half of the country, visited many different places, and met different people and relatives to whom he communicates and makes friend easily. Based on his age, Ghazi are in the stage of telegraphic in which children have achieved the competence of SVO structure although still in imperfect grammar which Ghazi has proven to be true for himself. However, Ghazi has his unique ways of pronouncing words which shows particular pattern which is interesting to describe. The study focuses on the pattern of Ghazi’s pronounciation of consonants in the initial and final position and vowels. The results show that: a) Ghazi finds difficulties in pronouncing some consonants in the initial position. The [p] and [b] phonemes become [ʨ] and [d] as in the example [pɔli] becomes [ʨɔyi], [bɔla] becomes [dɔya]; Some phonemes are not spoken at all such as ‘m’ in [mɔbil] which becomes [ɔbin]; b) Ghazi also finds it difficult to pronounce some consonants in the final position. For example, [ɑpel] becomes [ɑpɑn], [panjaŋ] becomes [dɑdɑn], and [mundur] becomes [undun]; c) Ghazi finds some difficulties in pronouncing certain consonants in the initial position but not in the final position. For example, ‘t’ in the initial position is changed such as [təman] becomes [ʨɔman] but ‘t’ in the final position such as [pəsɑwɑt]’ becomes [ʨuʨɑwɑt] which shows no error; d) Ghazi’s difficulties in pronouncing vowels are seen in the example such as [sərɑm],[gəlɑp], and [kərɑs] which become [ʨɔyɑm], [dɔyɑp], and [tɔyɑs] in which that [ə] phoneme becomes [ɔ]. Other vowels do not result in similar difficulties for him. Further researchers are encouraged to find the uniqueness of every child’s pattern of pronunciation to get insight on how children find their own way to a more accepted pronunciation.
A REVIEW ON MINDFULNESS AND NURSING STRESS AMONG NURSES
Authors: Said Zaini , Kheng Goh Lei
Published: September 2018

Previous research has been done on mindfulness and nursing stress but no review has been done to highlight the most up-to-date findings, to justify the recommendation of mindfulness training for the nursing field. The present paper aims to review the relevant studies, derive conclusions, and discuss future direction of research in this field. A total of 19 research papers were reviewed. The majority was intervention studies on the effects of mindfulness-training programs on nursing stress. Higher mindfulness is correlated with lower nursing stress. Mindfulness-based training programs were found to have significant positive effects on nursing stress and psychological well-being. The studies were found to have non-standardized intervention methods, inadequate research designs, small sample size, and lack of systematic follow-up on the sustainability of treatment effects, limiting the generalizability of the results. There is also a lack of research investigation into the underlying mechanism of action of mindfulness on nursing stress. Future research that addresses these limitations is indicated.

The Mosque as Heritage Site: The Al-Rashid at Fort Edmonton Park and the Politics of Location
Authors: Kurd Nadia
Published: September 2018

In 2013, the Al-Rashid Mosque celebrated a major milestone that almost did not happen: its 75th anniversary. As the oldest purpose-built mosque in Canada, the building has had a storied history: constructed with the combined support of a burgeoning Muslim community and the City of Edmonton, the Al-Rashid had served the Muslim and, more broadly, the Arab community until congregants outgrew the space during the 1980s. By 1992, the building sat in disrepair and was slated for demolition. Its move to Fort Edmonton Park the same year sparked controversy as debates over the building’s historic significance played out in town hall meetings and in the news media. As one newspaper columnist remarked, the fort was publicly forced to accept a “foreign intrusion.” This article discusses the history of the Al-Rashid Mosque, but also examines the social and political narratives the mosque articulates as one of Canada’s only Islamic heritage buildings. I am interested in the ways in which Edmonton’s diverse Muslim community along with Fort Edmonton Park currently animates the Muslim settlement history and how its location within the fort continues to raise questions over its heritage value today.
A refined model of chronic cerebral hypoperfusion resulting in cognitive impairment and a low mortality rate in rats

OBJECTIVE

The cognitive deficits of vascular dementia and the vasoocclusive state of moyamoya disease have often been mimicked with bilateral stenosis/occlusion of the common carotid artery (CCA) or internal carotid artery. However, the cerebral blood flow (CBF) declines abruptly in these models after ligation of the CCA, which differs from “chronic” cerebral hypoperfusion. While some modified but time-consuming techniques have used staged occlusion of both CCAs, others used microcoils for CCA stenosis, producing an adverse effect on the arterial endothelium. Thus, the authors developed a new chronic cerebral hypoperfusion (CCH) model with cognitive impairment and a low mortality rate in rats.

METHODS

Male Sprague-Dawley rats were subjected to unilateral CCA occlusion and contralateral induction of CCA stenosis (modified CCA occlusion [mCCAO]) or a sham operation. Cortical regional CBF (rCBF) was measured using laser speckle flowmetry. Cognitive function was assessed using a Barnes circular maze (BCM). MRI studies were performed 4 weeks after the operation to evaluate cervical and intracranial arteries and parenchymal injury. Behavioral and histological studies were performed at 4 and 8 weeks after surgery.

RESULTS

The mCCAO group revealed a gradual CBF reduction with a low mortality rate (2.3%). White matter degeneration was evident in the corpus callosum and corpus striatum. Although the cellular density declined in the hippocampus, MRI revealed no cerebral infarctions after mCCAO. Immunohistochemistry revealed upregulated inflammatory cells and angiogenesis in the hippocampus and cerebral cortex. Results of the BCM assessment indicated significant impairment in spatial learning and memory in the mCCAO group. Although some resolution of white matter injury was observed at 8 weeks, the animals still had cognitive impairment.

CONCLUSIONS

The mCCAO is a straightforward method of producing a CCH model in rats. It is associated with a low mortality rate and could potentially be used to investigate vascular disease, moyamoya disease, and CCH. This model was verified for an extended time point of 8 weeks after surgery.

Published: September 2018

Penelitian ini bertujuan mengetahui proses pembuatan biodiesel dengan memanfaatkan limbah minyak jelantah serta mengetahui perbedaan penggunaan alat antara reaktor dan panci terhadap kualitas biodiesel. Saat ini ketersediaan minyak jelantah sangat banyak dan hanya dibuang tanpa dimanfaatkan. Minyak jelantah yang digunakan berasal dari limbah minyak goreng bekas minimal dua kali penggorengan.

Pembuatan biodiesel dari minyak jelantah dilakukan dengan proses transesterifikasi dengan dibantu katalis untuk mereaksikannya. Karena minyak jelantah yang dipakai sebagai penelitian hanya 2 kali penggorengan, maka kadar free fatty acids tersebut tidak banyak. Proses transesterifikasi dengan metanol memakai perbandingan antara sodium metoksida dan minyak jelantah. Waktu yang diperlukan untuk proses transesterifikasi adalah 60 menit dengan suhu konstan 65 0C. Alat pereaksi yang digunakan sebagai perbandingan yaitu antara reaktor labu leher tiga dengan panci stainless steel tertutup. Hasil penelitian menunjukkan bahwa tidak ada perbedaan yang nyata antara pembuatan biodiesel dengan menggunakan reaktor dengan menggunakan panci. Untuk hasil parameter biodiesel dengan menggunakan kedua alat tersebut juga tidak banyak berpengaruh terhadap kualitas biodiesel itu tersendiri.
Evaluation of Energy Saving and Emission Reduction Effects for Electricity Retailers in China Based on Fuzzy Combination Weighting Method
Authors: Li Si , Niu Dongxiao , Wu Luofei
Published: September 2018

China’s electricity market is in the environment for a round of new electric power reform, energy planning and transformation and the carbon market construction. The current market players are in urgent need of implementing their own energy saving and emission reduction actions. Relatively extensive and systematic researches on the assessment of the energy saving and emission reduction effects for the power plants, power grid companies, and technical equipment have been carried out at home and abroad. However, there are still vacancies in the researches on those for electricity retailers emerged on the sales side. Based on the carding and analysis of related policies and guidance, in this paper, relevant indicators are considered to build the evaluation indicator system of the energy saving and emission reduction effects for electricity retailers. The combination weights are gained by means of analytic hierarchy process and entropy weight method. Then, after the combined empowerment of indicators, the multi-level fuzzy comprehensive evaluation of energy saving and emission reduction effects for electricity retailers is conducted. Finally, choosing 10 electricity retailers (numbered from A to J) as evaluation objects, this model is used for obtaining the evaluation results and ranking of energy saving and emission reduction effects of electricity retailers, which provides reasonable ideas for the construction of evaluation indicator system and effective comprehensive evaluation methods of energy saving and emission reduction effects for market players in the electricity sales side. The results of example analysis show that, from a single dimension, the best electricity retailers in market transactions, technical means, integrated energy services, management system, and social responsibilities are followed by B, J, D, G, C, or I. However, from a global perspective, the sorted evaluation results are D, J, I, A, H, G, E, B, F, and C, which reflects the overall energy saving and emission reduction effects of electricity retailers through the two-level fuzzy comprehensive evaluation.
Five-Frame Variable Phase-Shifting Method for Full-Range Spectral-Domain Optical Coherence Tomography
Authors: Lin Jiewen , Zhong Shuncong , Zhang Qiukun , Chen Weiqiang
Published: September 2018

In order to achieve a better complex conjugate artifacts (CCA) suppression, we propose a five-frame variable phase-shifting (FVP) method for spectral domain optical coherence tomography (SD-OCT). The traditional five-frame invariant phase-shifting (FIP) method employs five phase shifts correlate with the center wavelength. However, due to the effects of polychromatic errors, the FIP method cannot get excellent CCA suppression. In the present work, we employ FVP method using variable phase shifts which is dependent on all the wavelengths and therefore, theoretically, the system would have no effects of polychromatic errors. This is the reason why the FVP method would achieve better CCA suppression than the FIP method. Comparative studies between FIP and FVP methods are investigated in the work. Subsequently, we develop a homemade SD-OCT system involving a homemade spectrometer, by which the anterior segment of a rat’s eyeball is measured. The experimental results demonstrate that the quality of OCT images is significantly improved by using FVP method with an increase by a factor of 1.7 on the CCA suppression of SD-OCT. FVP provides a new strategy for complex conjugate artifacts suppression for spectral domain optical coherence tomography.

Published: September 2018

A flame retardant polyol (EP-DOPO) with epoxy functional groups was synthesized by reacting a 1,6-hexanediol glycidyl ether with a flame retardant 10-(2,5-dihydroxyphenyl)-10H-9-oxa-10-phospha-phenanthrene-10-oxide (DOPO). The polyurethane (EPPU) with enhanced heat resistance was prepared by the reaction of a polyol blend of EP-DOPO and polytetrahydrofuran (PolyTHF) at a ratio of 1:1 with isophorone diisocyanate. EPPU useful for the preparation of cables or coatings showed higher thermal decomposition temperature rather than that of reference polyurethane synthesized by the reaction between pure PolyTHF and isophorone diisocyanate by thermogravimetric analysis. Further study of the polyurethane as a toughening agent for epoxy polymers was carried out. Epoxy compositions consisting of bisphenol A epoxy resin and dicyandiamide as a hardener have a brittle property allowing crack propagation after cure. Polyurethane plays an important role as an impact modifier to prevent from cracks of epoxy polymers. Various contents of EPPU were added into epoxy compositions to measure the physical property changes of epoxy polymers. The tensile and flexural strengths of the cured specimen were compared with those of epoxy compositions including reference polyurethane. Furthermore, the crosslink density of the cured epoxy compositions was compared.

The isolated terawatt (TW) attosecond (as) hard X-ray pulse will expand the scope of ultrafast science, including the examination of phenomena that have not been studied before, such as the dynamics of electron clouds in atoms, single-molecule imaging, and examining the dynamics of hollow atoms. Therefore, several schemes for the generation of an isolated TW-as X-ray pulse in X-ray free electron laser (XFEL) facilities have been proposed with the manipulation of electron properties such as emittance or current. In a multi-spike scheme, a series of current spikes were employed to amplify the X-ray pulse. A single-spike scheme in which a TW-as X-ray pulse can be generated by a single current spike was investigated for ideal parameters for the XFEL machine. This paper reviews the proposed schemes and assesses the feasibility of each scheme.

Published: September 2018

Decentralization of on-site and in-site trace metal analysis has been a key topic over the last 30 years, owing to the increasing need for environmental protection as well as industrial and health-based field applications. In trace (and ultratrace) metal analysis, electrochemical stripping analysis with mercury (or bismuth) screen-printed film electrodes has shown a fast growth in popularity thanks to the good limits of detection, the ease of application in the field, and the low cost. Moreover, the availability of new wall-jet flow cells has opened the opportunity for their use in in situ industrial monitoring. The analytical figures of merit in stripping voltammetry with screen-printed electrodes (SPEs) under decentralized conditions and/or with sensor arrays are heavily affected by some analytical factors, primarily the presence of a pseudo-reference electrode, the efficiency of mass transport during the preconcentration step, and the need for external calibration. A careful model investigation of the analytical parameters for an efficient use of SPEs in decentralized conditions has been undertaken and discussed. Different instrumental approaches were investigated, comparing optimized batch conditions and flow cell operation under either continuous flow or stopped-flow sample injection. The stripping efficiency under wall-jet flow conditions was found to be high and comparable to that in batch conditions, leading to sub-ppb (μg/L) limit of detection (LOD) figures. Finally, external calibration in stripping voltammetry was studied as a viable alternative to conventional standard addition quantitation. Results showed, indeed, that external calibration was demonstrated to be reliable for quantitation of Pb and Cd in real water samples.

The present study aims to evaluate the capability of the Tropical Rainfall Measurement Mission (TRMM), Multi-satellite Precipitation Analysis (TMPA), version 7 (TRMM-3B42-V7) precipitation product to estimate appropriate precipitation rates in the Upper Indus Basin (UIB) by analyzing the dependency of the estimates’ accuracies on the time scale. To that avail, various statistical analyses and comparison of Multisatellite Precipitation Analysis (TMPA) products with gauge measurements in the UIB are carried out. The dependency of the TMPA estimates’ quality on the aggregation time scale is analyzed by comparisons of daily, monthly, seasonal and annual sums for the UIB. The results show considerable biases in the TMPA Tropical Rainfall Measurement Mission (TRMM) precipitation estimates for the UIB, as well as high numbers of false alarms and miss ratios. The correlation of the TMPA estimates with ground-based gauge data increases considerably and almost in a linear fashion with increasing temporal aggregation, i.e., time scale. There is a predominant trend of underestimation of the TRMM product across the UIB at most of the gauge stations, i.e., TRMM-estimated rainfall is generally lower than the gauge-measured rainfall. For the seasonal aggregates, the bias is mostly positive for the summer but predominantly negative for the winter season, thereby showing a slight overestimation of the precipitation in summer and underestimation in winter. The results of the study suggest that, in spite of these discrepancies between TMPA estimates and gauge data, the use of the former in hydrological watershed modeling undertaken by the authors may be a valuable alternative in data-scarce regions like the UIB, but still must be taken with a grain of salt.

The development of a sustainable aquaculture industry requires the closing of the life-cycle of a potential species in captivity, and the establishment of breeding selection programs using hatchery-produced breeding stocks. The greater amberjack Seriola dumerili is a cosmopolitan pelagic species that has been considered as a good candidate for the species diversification of aquaculture production in the Mediterranean region. However, commercial production is still very limited due to bottlenecks in reproduction, larval rearing and management control during grow out. The aim of the present study was to examine the reproductive development of hatchery-produced greater amberjack and to develop a spawning induction protocol based on the use of gonadotropin releasing hormone agonist (GnRHa) in a controlled-release delivery system. The results showed that hatchery-produced greater amberjack undergo normal gametogenesis and can be induced to undergo maturation, ovulation and spawning after multiple administrations of GnRHa implants, over an extended spawning period lasting from May to September in the Canary Islands, Spain. The use of GnRHa-delivery systems resulted in multiple spawns of fertilized and viable eggs. Egg production was high and egg quality adequate for the implementation of larval rearing for commercial purposes. The handling required to administer the GnRHa implants during the prolonged spawning season did not result in any negative effect on the welfare and reproductive performance of the fish based on evaluation of several biochemical parameters. The developed reproduction control method shows great potential to advance the commercial production of greater amberjack, by enabling the use of hatchery-produced broodstocks for further breeding selection.

Combustion will play a major part in fulfilling the world’s energy demand in the next 20 years. Therefore, it is necessary to understand the fundamentals of the flame–wall interaction (FWI), which takes place in internal combustion engines or gas turbines. The FWI can increase heat losses, increase pollutant formations and lowers efficiencies. In this work, a Large Eddy Simulation combined with a tabulated chemistry approach is used to investigate the transient near wall behavior of a turbulent premixed stoichiometric methane flame. This sidewall quenching configuration is based on an experimental burner with non-homogeneous turbulence and an actively cooled wall. The burner was used in a previous study for validation purposes. The transient behavior of the movement of the flame tip is analyzed by categorizing it into three different scenarios: an upstream, a downstream and a jump-like upstream movement. The distributions of the wall heat flux, the quenching distance or the detachment of the maximum heat flux and the quenching point are strongly dependent on this movement. The highest heat fluxes appear mostly at the jump-like movement because the flame behaves locally like a head-on quenching flame.

The ultrasound-assisted extraction (UAE) of oleuropein (OLE), verbascoside (VER), and luteolin-4′-O-glucoside (L4OG), as the major phenolics from olive leaves, was optimized using response surface methodology (RSM). A Box–Behnken design (BBD) was used to monitor the effect of different modes of ultrasound operation (pulsed and continuous), liquid–solid (L–S) ratio, and sonication time on each phenolic yield. The yield of UAE and conventional solid extraction (CSE) was determined after performing ultrahigh-performance liquid chromatography with a diode-array detector (UHPLC-DAD) analysis on the extracts. The results suggested that, under optimal conditions, the concentrations of OLE, VER, and L4OG were 13.386, 0.363, and 0.527 mg/g of dry powdered olive leaves (DPOL), respectively. Verification of experiments was carried out under the modified optimal conditions and the relative errors between the predicted and experimental values were dependent on the examined phenolic compound (OLE 8.63%, VER 11.3%, and L4OG 22.48%). In comparison with CSE, UAE improved the yields of OLE, VER, and L4OG (32.6%, 41.8%, and 47.5%, respectively, after 1 min) at a temperature of 60 °C, an L–S ratio of 15 (v/w), and in the continuous mode of UAE. We demonstrated that the UAE technique is an efficient method for enhancing yields of OLE, VER, and L4OG in olive-leaf extracts, while the chosen model was adequate to optimize the extraction of major phenolic compounds from olive leaves.
