Outcomes Study

The purpose of this article is to synthesize the extant research on peer-mediated interventions (PMIs) with English language learners (ELLs) in kindergarten through Grade 12. Fourteen studies that were published in peer-reviewed journals from 1983 to 2013 were examined in terms of study characteristics, the effects on academic outcomes, study quality, and overall effectiveness. Structured, heterogeneous grouping was used in the 10 peer pairing and 4 collaborative/cooperative grouping PMIs with ELLs. Eight of the 14 studies included high methodological quality. Overall, PMIs with ELLs are associated with medium to large effects on measures of phonemic awareness, vocabulary, and comprehension when compared to teacher-mediated comparison conditions. More research on PMIs with ELLs in high school and across core content areas, particularly mathematics, is warranted. Implications and future research for PMIs with ELLs are discussed.

Subject. This article examines the non-financial sector debt ratio relative to the GDP of emerging and developed market economies. Objectives. The article aims to find out what institutional units show debt growth or reduction, what causes and conditions prevent debt decline or lead to its growth in different countries and sectors, and highlight the foundations of public policy in this area. Methods. For the study, I used a cross-country comparative analysis, grouping method, and graphical and trend analyses. The study covers 43 market economies, including 26 developed and 17 emerging ones. The time period is from Q4 2001 to Q4 2019. Results. The article identifies and describes the structural debt changes that have taken place since 2008, which include a reduction in private sector leverage and rising public sector debt in developed market economies, and accelerated growth in the non-financial corporations and households' debt in emerging market economies. Conclusions and Relevance. Given the different conditions of access to the capital market and the institutional differences between developed and emerging market economies, different approaches to debt management are needed. The identified trends are important to develop non-financial sector debt management policies, including both fiscal and monetary policies.

The main purpose of this paper is to model, simulate, and improve the performance of different 9 × 9 PV array configurations under different Partial Shading Conditions (PSCs) in order to extract the maximum power by defeat the mismatching power losses. Hence, PSCs reduces the performance of Photovoltaic (PV) arrays and increase the Local Maximum Power Points (LMPPs) on output characteristics P-V due to mismatching power losses between the PV panels. For this, Total-CrossTied (TCT) , and proposed Magic Square View (MSV) PV array topologies are considered for the study under Short Narrow shading patterns. PV array configurations enhancements and theirinvestigations are carried out with regard to the comparison of the Global peak of outlet power (GP).The parameters of the PV array configurations are performed in MATLAB/Simulink software.

Indicators are important tools to guide and assist decision-makers. They are also important to get to know the scenario of a given place and monitor its development. This study aimed to analyze the behavior of the municipalities of Marajó-PA through indicators that cover social, economic, housing and sanitation, using a statistical technique of multivariate analysis to group these into a small number of homogeneous groups. In order to choose the indicators, we carried out a checklist of national, regional and local academic papers dealing with sustainability. Then, the indicators were standardized according to the different units and scales of measurement, not influencing the result and presenting similar weights in the calculation of the similarity coefficient. The measure of dissimilarity used was the euclidean distance and for the composition of the groupings the Ward and k-Means methods were applied. The result obtained using Ward’s hierarchical grouping method enabled the reduction of the numbers of municipalities to a number of 4 probable groups with similar attributes within the group and distinct among the others. It also presented a cofenetic correlation coefficient (CCC) of (r = 0.81), indicating a good degree of fit between the dendrogram and the dissimilarity matrix. The results indicated that the formation of the clusters and the municipalities integrated in them presented similarity both in the hierarchical and non-hierarchical methods. In the k-means method it was found that almost all municipalities that make territorial division remained within the same group.

Difficult Issue

The immovable nature of passing on packages through multi -bounce middle hubs is a critical problem in the versatile impromptu organizations (MANETs). The disseminated versatile hubs set up associations with structure the MANET, which may incorporate childish and getting into mischief hubs. Suggestion based trust the board is proposed in the creating as a system to evaluate through the acting up hubs while looking for a bundle conveyance course. Nonetheless, building a trust model that embraces suggestions by different hubs in the organization is a difficult issue because of the danger of deceptive proposals like reviling, voting form stuffing, and conspiracy. we examines the issues identified with assaults presented by getting rowdy hubs while proliferating suggestions in the current trust models. We propose a suggestion based trust model with a safeguard plot, which uses grouping method to progressively sift through assaults identified with exploitative proposals between certain time dependent on number of collaborations, similarity of data and closeness between the hubs. We evaluate the trust degree as two cases like direct and indirect trust values between neighboring nodes from source. To form a clustering routing network from similar trust values from S to D.The model is experimentally tried under a few portable and detached geographies in which hubs experience changes in their local prompting regular course changes. The observational investigation shows heartiness and exactness of the trust model in a dynamic MANET climate.
