Random-Site Cation Ordering and Dielectric Properties of PbMg1/3Nb2/3O3-PbSc1/2Nb1/2O3

(1 − x)PbMg1/3Nb2/3O3-(x)PbSc1/2Nb1/2O3 (PMN-PSN) solid solution crystals have been grown by the flux method in the whole concentration range. X-ray supercell reflections due to B-cation ordering were observed for as-grown crystals from the 0.1 ≤ x ≤ 0.65 compositional range. Though the ordered domains are rather large (∼50 nm) the relaxor-like dielectric behavior is observed for compositions with x < 0.6. The diffusion of the dielectric permittivity maximum in as-grown crystals is the lowest at x = 0.6 and increases towards the end members of solid solution. Such behavior is explained within a Bragg-Williams approach by employing the random layer model. At x ∼ 0.6 the excitation energy determined from the Vogel-Fulcher relation exhibits a jump which we regard to changing the kind of the polar regions from PbMg1/3Nb2/3O3 to PbSc1/2Nb1/2O3 related type.
Non-Pharmacological Management of Burn-related Pain and Distress in Children: A Systematic Review and Meta-Analysis Study

Introduction: Pain and distress during burn-related painful procedures are common. Various non-pharmacological interventions are used to control pain and distress during burn-related painful procedures. Hereby, this study aimed to systematically review the recent literature regarding the efficacy of the non-pharmacological interventions to control pain perception and distress in children undergoing painful burn management procedures. Methods: the data sources were Cochrane Central Register of Controlled Trials, CINAHL, MEDLINE, and Science Direct databases were searched through 1989-2020. Data extraction was performed by two independent researchers. Selection criteria: Participants included children from birth to nineteen years. Only randomized controlled trials (RCTs) or RCT crossovers that had a no-treatment control comparison were eligible for inclusion in the analyses. Data analysis: The risk of bias was assessed using the Cochrane risk-of-bias tool for randomized trials. Review Manager 5.4 software was used to calculate standardized mean differences (SMDs) with 95% confidence intervals (CIs). Results: Out of 244 studies found, 15 trials met the inclusion criteria for further review with non-pharmacological interventions that included distraction (n=8), VR (n=5), hypnosis (n=1), and massage therapy (n=1). However, 13 trials out of 15 were included in the meta-analysis with 685 participants. Meta-analysis showed large effects of distraction intervention on self-reported pain (SMD -1.64, 95% CI -3.16, -0.12), observer-reported pain (SMD -3.02, 95% CI -5.85, -0.19), and behavioral distress (SMD -2.82, 95% CI -5.50, -0.14). Besides, distraction intervention showed moderate effects on self-reported distress (SMD -0.33, 95% CI -0.58, -0.08), and no effect on behavioral pain (SMD -1.06, 95% CI -2.44, 0.31). On the other hand, VR reported a large effect on self-reported pain (SMD 1.41, 95% CI -2.52, -0.30), a moderate effect on observer-reported pain (SMD -0.56, 95% CI -0.90, -0.22), and no effect on the behavioral pain (SMD -0.48, 95% CI -1.04, 0.08). Overall, the quality of derived evidence was downgraded due to study limitations, inconsistency, and imprecision. Conclusion: Distraction and VR are effective non-pharmacological interventions in reducing the pain perception and distress in children during painful burn management procedures.
The Importance of Residential Labor Market Networks

We specify and implement a test for the presence and importance of labor market network based on residential proximity in determining the establishments at which people work. Using matched employer-employee data at the establishment level, we measure the importance of these network effects for groups broken out by race, ethnicity, and various measures of skill. The evidence indicates that these types of labor market networks do exist and play an important role in determining the establishments where workers work, that they are more important for minorities and the less-skilled, especially among Hispanics, and that these networks appear to be race-based.

The impact of parental leave duration on later career

We investigate the existence of causal mechanisms from parental leave duration to subsequent wages. Our instrumental variable is a French reform giving financial incentives to take a parental leave. Two administrative datasets provide us with information on wages and familial background from 1976 to 2005. In our context, panel data estimations potentially suffer from unobserved heterogeneity, endogeneity and selection. We implement an innovative procedure proposed by Semykina and Wooldridge (2005) to take into account these three problems simultaneously. We find that parental leave duration has a significant negative causal impact on later wages.
The Effect of Task Planning and Genderon WritingFluency: A Case Study of Undergraduate Students at AMU

Tasked Based Language Teaching (TBLT) has widely provided learners withsome opportunities to learn spoken and written language through learning activities in the major of English Language Teaching (ELT). It offers the student an opportunity to be taught more naturally.In the recent years, that there is a massive growth of interest in examining differential effects of task planning conditionson fluency, accuracy and complexity in English as a second language (ESL) context but, the present study explored the impacts of task planningand gender on ESL learners’ written performance in terms offluency. To this end, five-hundred undergraduate English Language Learners, both male and female (within the age range of 18-24) have been recruited from Aligarh Muslim University. Two tasks were chosen as instruments for data collection. One is a narrative task (as a pre-task for five-hundred) and the other isan argumentativeessay (for two-hundred one)to measure the fluency of the participants’ written production, under different planning conditions (pretask planning, within-task planning, and no planning). One-way MANOVA was employed as the statistical means of analysis. The findings revealed a significant effect of task planning and gender under different planning conditions inwords per minute (the number of words produced by the participants divided by the time they spent on each assignment) and syllables per minute (The number of syllables that the participants produced divided by the minutes they spent on production) regarding fluency.

Adherence to complementary gender stereotypes and attitudes towards male infidelity

This study assesses the effect of adherence to complementary gender stereotypes on attitudes toward male infidelity. It aims to contribute to the literature on the implication of stereotypes in the maintenance of disproportionate social and sexual conditions (Eagly & Wood, 1999; Jost & Kay, 2005; Kahalon, 2018). It tests the hypothesis that adherence to complementary gender stereotypes has an effect on attitudes towards male infidelity. 87 students of both sexes, enrolled in the psychology unit of the University of Dschang (Cameroon), were selected to participate voluntarily in the study. Their age varies between 15 and 41 years (M. = 21.44; SD = 4.71). The procedure of data collection was inspired by Jost and Kay’s work (2005). Participants responded to measures of complementary gender stereotypes, simple gender stereotypes, and attitudes toward male infidelity. The data collected provides empirical support for the hypothesis of the study. Indeed, adherence to complementary gender stereotypes positively affects attitude towards male infidelity (β = 16.67; t = 3.58; p ˂ .02), just as much as adherence to simple gender stereotypes (β = 19.23; t = 5.29; p ˂ .01). It is concluded that men and women mutually participate in maintaining disproportionate social and sexual conditions.
Do I Trust this Stranger? Generalized Trust and the Governance of Online Communities

Online peer production communities such as Wikipedia typically rely on a distinct class of users, called administrators, to enforce cooperation when good faith collaboration fails. Assessing one’s intentions is a complex task, however, especially when operating under time-pressure with a limited number of (costly to collect) cues. In such situations, individuals typically rely on simplifying heuristics to make decisions, at the cost of precision. In this paper, we hypothesize that administrators’ community governance policy might be influenced by general trust attitudes acquired mostly out of the Wikipedia context. We use a decontextualized online experiment to elicit levels of trust in strangers in a sample of 58 English Wikipedia administrators. We show that low-trusting admins exercise their policing rights significantly more (e.g., block about 81% more users than high trusting types on average). We conclude that efficiency gains might be reaped from the further development of tools aimed at inferring users’ intentions from digital trace data.
Ameliorating effects of Cissus populnea aqueous stem bark extract on some parameters in diabetic Wistar rats

This study investigated the effects of aqueous stem bark of Cissus populnea (C.p) extract on some parameters in diabetic Wistar rats. Fresh stem bark of C.p was air dried, pulverized, and mixed with distilled water at room temperature for 72 h; then flittered (11 m) and the dried filtrate (C.p extract) was used for the animals treatment, which was in 5 groups of 6 rats each: Group 1: normal control, Group 2: treated with 200 mg/kg body weight (b.w) of C.p extract; Group 3: treated with 500 mg/kg b.w of C.p extract, Group 4: treated with 100 mg/kg b.w metformin, while Group 5 untreated, after groups 2-5 were induced with diabetes mellitus with alloxan, the study was for 21 days. Treatment of groups 2 and 3 with C.p extract restored the blood glucose to level comparable to group 1, p > 0.05, but significantly different to group 5, p < 0.05. Treatment of group 3 with C.p extract stabilized the antioxidant enzymes activity without significant difference p > 0.05, when compared to groups 1 and 4; but significantly differed from group 5, p < 0.05. The pancreatic histology of groups 2 and 3 appeared normal, while group 5 had tissue atrophy. The results showed that C.p extract had potentials to modulate glucose, MDA and antioxidant enzymes activity, with no pathological effect on the pancreas. Therefore, further work is suggested for possible extrapolation to diabetic treatment.
Evaluation of Machine Learning Algorithms in Predicting the Next SQL Query from the Future

Prediction of the next SQL query from the user, given her sequence of queries until the current timestep, during an ongoing interaction session of the user with the database, can help in speculative query processing and increased interactivity. While existing machine learning-- (ML) based approaches use recommender systems to suggest relevant queries to a user, there has been no exhaustive study on applying temporal predictors to predict the next user issued query. In this work, we experimentally compare ML algorithms in predicting the immediate next future query in an interaction workload, given the current user query or the sequence of queries in a user session thus far. As a part of this, we propose the adaptation of two powerful temporal predictors: (a) Recurrent Neural Networks (RNNs) and (b) a Reinforcement Learning approach called Q-Learning that uses Markov Decision Processes. We represent each query as a comprehensive set of fragment embeddings that not only captures the SQL operators, attributes, and relations but also the arithmetic comparison operators and constants that occur in the query. Our experiments on two real-world datasets show the effectiveness of temporal predictors against the baseline recommender systems in predicting the structural fragments in a query w.r. t. both quality and time. Besides showing that RNNs can be used to synthesize novel queries, we find that exact Q-Learning outperforms RNNs despite predicting the next query entirely from the historical query logs.
Out-of-plane local mechanism analysis with finite element method

Abstract The stability check of masonry structures is a debated problem in Italy that poses serious problems for its extensive use. Indeed, the danger of out of plane collapse of masonry walls, which is one of the more challenging to evaluate, is traditionally addressed not using finite element models (FEM). The power of FEM is not properly used and some simplified method are preferred. In this paper the use of the thrust surface is suggested. This concept allows to to evaluate the eccentricity of the membrane stresses using the FEM method. For this purpose a sophisticated, layered, finite element with a no-tension material is used. To model a no-tension material we used the smeared crack method as it is not mesh-dependent and it is well known since the early ’80 in an ASCE Report [1]. The described element has been implemented by the author in the program Nòlian by Softing.
Comparison of velocity-based and traditional 1RM-percent- based prescription on acute kinetic and kinematic variables

Purpose: This study compared kinetic and kinematic data from three different velocity-based training (VBT) sessions and a 1-repetition maximum (1RM) percent-based training (PBT) session using full-depth, free-weight back squats with maximal concentric effort. Methods: Fifteen strength-trained men performed four randomized resistance-training sessions 96-hours apart: PBT session involved five sets of five repetitions using 80%1RM; load-velocity profile (LVP) session contained five sets of five repetitions with a load that could be adjusted to achieve a target velocity established from an individualized LVP equation at 80%1RM; fixed sets 20% velocity loss threshold (FSVL20) session that consisted of five sets at 80%1RM but sets were terminated once the mean velocity (MV) dropped below 20% of the threshold velocity or when five repetitions were completed per set; variable sets 20% velocity loss threshold (VSVL20) session comprised 25-repetitions in total, but participants performed as many repetitions in a set as possible until the 20% velocity loss threshold was exceeded. Results: When averaged across all repetitions, MV and peak velocity (PV) were significantly (p<0.05) faster during the LVP (MV: ES=1.05; PV: ES=1.12) and FSVL20 (MV: ES=0.81; PV: ES=0.98) sessions compared to PBT. Mean time under tension (TUT) and concentric TUT were significantly less during the LVP session compared to PBT. FSVL20 session had significantly less repetitions, total TUT and concentric TUT than PBT. No significant differences were found for all other measurements between any of the sessions. Conclusions: VBT permits faster velocities, avoids additional unnecessary mechanical stress but maintains similar measures of force and power output compared to strength-oriented PBT.
Ethnic Socialization in Current and Prospective Parents

Few studies have examined whether the manner in which one has been parented impacts one’s subsequent parenting style regarding ethnic socialization. We examined this question in current and prospective parents. First, we found that receiving greater familial ethnic socialization is significantly correlated with stronger subsequent parental ethnic socialization (PES) for both current and prospective parents. Second, we found that PES did not significantly differ between current and prospective parents. Third, given the limited research examining the ethnic socialization experiences of those who are White, we examined these questions specifically for our White participants. Our findings persisted when we examined all ethnicities together and when we examined White participants alone.
Is Multicultural Counseling Competence Outdated or Underdeveloped, or in Need of Refinement? A Response to Ridley et al.

This paper provides a response to Ridley et al.’s Major Contribution on the state of multicultural counseling competence (MCC) and their proposed refinement and extension of this construct. They pose the following multiprong question: “Is multicultural counseling competence becoming outdated and supplanted, or is it underdeveloped and in need of refinement? ” We use this question to examine the MCC model that Ridley et al. have proposed in this Major Contribution. We summarize and critique each paper, and close with our own conclusions about the above question. We are concerned that the characteristics of the clinicians seem to be secondary to MCC. We also question the lack of focus on the sociopolitical context and the limited inclusion of diverse scholarship in creating a universal MCC model.
Multicultural Counseling Competence: A Construct in Search of Operationalization

The work of many great scholars has proliferated a sizable body of knowledge on the construct of multicultural counseling competence. However, the construct’s operationalization remains obscured, perplexing, and frustrating to practitioners who attempt to translate the scholarship into practice. We identify ten definitional problems that prevent the construct from evolving into a cohesive form that can inform practitioners’ work. These include: an indistinct purpose, culturally general/culturally specific divide, terminological interchange, confusing competency with competence, lack of integration, no definition, ambiguity, equivocation, circular reasoning, and divergence. Furthermore, the three major models of the construct—skills-based, adaptation, and process-oriented—share six limitations. They lack interdependence, prescriptive methods, deep incorporation of culture, coherent designs, conclusive research support, and they are oversimplifications. We call on the community of our fellow scholars to collaborate in reconceptualizing this complex construct into a sound, applicable guide for practitioners’ work with diverse clients.
The Racial Politics of Emotion: Teaching an Interdisciplinary Border Institute in the Midwest

The militarization of the U.S.-Mexico border, criminalization of immigrants and migrants, and humanitarian emergency surrounding the border has negatively impacted students and schools. Responding to the impact of U.S. border politics on education, we taught a week-long institute for local teachers to learn about the histories and lived experiences connecting the Central American, Mexican, and U.S. borders. During the institute we asked participants—who were predominantly white K-12 teachers—to reflect on their learning experiences in personal journals. The aim of this study was to investigate the racial politics of emotion when confronting border issues in a classroom setting. Taking an interdisciplinary approach to our analysis, we conducted qualitative content analysis and close readings of twenty-one teacher’s journals to determine patterns in the emotional response’s teachers had to the histories, testimonies, audio, and visual accounts to which they were exposed through readings and seminars. The results of our analysis reveal that emotions were used by participants to maintain racial boundaries and reinforce race-based notions of national belonging, but also to challenge injustice both in and beyond classroom settings. The findings have significant implications about the impact that ethnic studies programs and critical race theory curriculum may have on teacher education.
Workforce Skills in Family Support: A Systematic Review

Purpose: Skills used in the practice of family support workforce are implemented in different settings and frameworks. The conceptual assumptions and epistemological frameworks of diversity are a challenge. Various paradigms of intervention, different sectors, and disciplinary involvement indicate the need to systematize and clarify knowledge in the field. Method: Using preferred reporting items for systematic reviews and meta-analyses guidelines, a systematic review was conducted, including qualitative, quantitative, and mixed-method studies on skills in the practice of family support. Results: The literature was collected in an exhaustive search of several databases, where a set of 8,489 papers was selected. The workforce skills described were the qualities of the professionals, technical skills, and specific knowledge. Discussion: Most of the studies were literature reviews, did not define specific skills, had very small samples, and had issues with bias. We discuss implications for practice in social work as well as the gaps to be covered in further research of family support.
Pronunciation and Task-Based Instruction: Effects of a Classroom Intervention

Explicit pronunciation instruction enhances production of intelligible, comprehensible, and fluent second language (L2) speech. Additionally, task-based instruction (TBI) enhances the production of segmentals and suprasegmentals, and promotes awareness of L2 forms in pronunciation. Since most previous research on TBI in L2 pronunciation learning has been carried out in laboratory settings, it is necessary to investigate how the implementation of tasks that differ in complexity in actual classroom settings could benefit L2 pronunciation learners. This classroom-based study investigated the effects of combining focus on form and TBI in L2 pronunciation instruction in the production of comprehensible, fluent, and L2-accented speech in English-as-a-foreign-language learners. Although the results of the study present modest gains, they make a case for the inclusion of explicit pronunciation instruction and tasks that differ in complexity to help learners develop pronunciation skills. Responding to recent calls for more classroom-based research that demonstrates how pronunciation can be implemented in systematic and principled ways, the results of this study are discussed in terms of implications and pedagogical recommendations for L2 pronunciation teaching and learning.
Exploring Maternal Health in Ethiopia Using Indigenous Approaches: Policy and Practice Implications

The World Health Organization reports reveal that the average risk of dying from pregnancy-related causes in sub-Saharan Africa is about 1 in 45 compared to 1 in 5,400 in high-income countries. In Ethiopia, maternal mortality remains a tremendous problem. Several studies associate the high maternal mortality ratio to the widespread practice of home birth, household income, and lack of transportation. Absent from the findings of these studies is any discussion of the sociocultural contexts that might influence maternal health service utilization. Birthing bears cultural significance accompanied by rituals. Thus, any solution to maternal health problems must consider the sociocultural and grassroots context. It is important to learn the needs and priorities of the mothers who are targets of maternal health policies. Using Indigenous approaches, this study examines the gaps in Ethiopian maternal health policies and programs. The study also identifies culturally relevant solutions that address the needs of communities.
