The purpose of the present study is to examine associations between quality of teacher–child relationships from preschool through third grade and children’s third-grade achievement using Phases I, II, and III data from the National Institute of Child Health and Human Development Study of Early Care and Education, a prospective study of 1,364 children from birth through sixth grade. There are three main findings. First, positive associations were found between quality of teacher–child relationships and achievement. Second, high quality teacher–child relationships buffered children from the negative effects of insecure or other maternal attachment on achievement. Third, the effect of quality of teacher–child relationships on achievement was mediated through child and teacher behaviors in the classroom. In sum, high quality teacher–child relationships fostered children’s achievement. Implications for educational practice are discussed.

Objective To update a 2010 meta-review of systematic reviews of effective interventions to support carers of ill, disabled, or older adults. In this article, we report the most promising interventions based on the best available evidence. Methods Rapid meta-review of systematic reviews published from January 2009 to 2016. Results Sixty-one systematic reviews were included (27 high quality, 25 medium quality, and nine low quality). The quality of reviews has improved since the original review, but primary studies remain limited in quality and quantity. Fourteen high quality reviews focused on carers of people with dementia, four on carers of those with cancer, four on carers of people with stroke, three on carers of those at the end of life with various conditions, and two on carers of people with mental health problems. Multicomponent interventions featured prominently, emphasizing psychosocial or psychoeducational content, education and training. Improved outcomes for carers were reported for mental health, burden and stress, and wellbeing or quality of life. Negative effects were reported in reviews of respite care. As with earlier work, we found little robust evidence on the cost-effectiveness of reviewed interventions. Conclusions There is no ‘one size fits all’ intervention to support carers. There is potential for effective support in specific groups of carers, such as shared learning, cognitive reframing, meditation, and computer-delivered psychosocial support for carers of people with dementia. For carers of people with cancer, effective support may include psychosocial interventions, art therapy, and counselling. Carers of people with stroke may also benefit from counselling. More good quality, theory-based, primary research is needed.

The professionalism of a higher school teacher and the quality of their work largely determine the quality of training of future graduates who are ready for professional advancement in the context of the development of new high-tech technologies and the increasing demands of partners in the real sector of the economy. In this regard, the research aims to find ways and mechanisms to improve the professionalism of the teacher, their training, and retraining in contemporary educational practice. The article presents the research results obtained at the Department of Pedagogy and Psychology of Penza State Technical University (Penz STU) on the concerned problems. The novelty of the research lies in the effective ideas, approaches, and principles of constructive problem-solving in educational practice proposed based on the analysis of normative, historical, pedagogical, and scientific literature of foreign (Germany, Great Britain, and the USA) and domestic practices. It is shown that the studied and characterized models of improving the professionalism and training of academic staff in higher education, identified leading principles underlying the implementation of these models, and the relationships among the goals, results, and conditions of training and retraining of academic staff in the realities of today can be in demand and successfully implemented. As promising areas for improving the professionalism of a higher school teacher to effectively address issues of high-quality training of graduates, the authors offer to provide pedagogical support as the most productive technology to support a novice teacher during their professional adjustment, conducting monitoring of the effectiveness of teachers’ activities to improve the quality of their professionalism, and encouraging effective and efficient work, as well as providing social partnership and integration of all types of educational resources.

The search for effective methods of management is one of the strategic directions of economic development. To obtain high-quality products, organizations should manage nonconformities and causes of product defects. The paper focuses on the analysis of groups of defects of welded joints using statistical methods. Welding process was considered as one of the processes of management. The possible causes of nonconformities were indicated. The method of failure modes and effects analysis was used to quantify the level of risk. A matrix of consequences and probabilities was presented, and critical risks and risk situations were selected. The proposed measures to eliminate or minimize negative effects enable identification of problem areas of the life cycle of welded structures.

<p>Panili Indonesia sudah dikenal di pasar intenasional dengan nama Java Vanilla Beans dengan kualitas yang cukup baik. Masalahnya mampukah Indonesia mempertahankan kontinuitas penawarannya sesuai dengan kualitas yang diinginkan pasar. Penelitian ini betujuan mcnganalisis: (1) kinerja penawaran atau produksi melalui peilaku luas areal dan produktivitas tanaman panili; (2) peilaku penawaran ekspor komoditas panili ke Jcrman dan Amerika Seikat (AS); dan (3) peilaku harga domestik dan harga ekspor komoditas panili. Data yang digunakan merupakan data sckundcr rentang waktu (lime series) tahunan: 1975 - 2000 pada tingkat nasional dan intenasional. Analisis data menggunakan pendekatan ckonometik dengan metode 2SLS. Hasil analisis menyimpul- kan: (1) luas tanam menghasilkan dipengaruhi oleh upah tenaga kerja secara ncgatif dalam jangka pendek luas tanaman menghasilkan belum rcsponsif terhadap perubahan tingkat upah, akan tetapi dalam jangka panjang menjadi responsif, (2) produktivitas panili dipengaruhi secara positif oleh harga panili domestik, namun produktivitas tidak rcsponsif terhadap perubahan harga; (3) ekspor panili Indonesia ke Jcrman dan AS dipengaruhi oleh ekspor tahun sebelumnya. Hal ini menginformasikan bahwa kegiatan ekspor tersebut terkait dengan kepcrcayaan antara ekspotir Indonesia dengan importir Jerman dan AS; (4) transmisi harga ekspor ke harga yang diteima petani sangat lemah, sementara transmisi harga dunia ke harga ekspor cukup erat Hal ini dapat dilihat dai tidak adanya pengaruh harga ekspor terhadap harga domestik, sedangkan harga ekspor sangat dipengaruhi oleh harga dunia; (5) upaya pengembangan panili di Indonesia lebih diarahkan pada peningkatan kualitas hasil, perluasan tanaman yang berlcbihan hendaknya memperhatikan kecenderungan permintaan ekspor; (6) untuk menjaga pangsa pasar panili Indonesia di pasar intenasional hendaknya tetap meningkatkan daya saing, baik dai segi kualitas maupun harga.</p><p>Kata kunci: Panili, ekspor, Java vanilla, Indonesia, penawaran<br /><br /></p><p><strong>ABSTRACT</strong><br /><br /><strong>Indonesian Vanilla Expots</strong><br /><br />Indonesian vanilla, Java Vanilla Beans, is widely known in intenational market. It is also regarded as high quality vanilla. The main concen for Indonesian expoters is to fulill the continuity of the supply for the quality as demanded. This study aims to analyze: (1) the effects of acreage and yields on supply and production of Indonesian vanilla; (2) the exports of Indonesian vanilla to Germany and the U.S.; (3) the domestic pices and export prices of Indonesian vanilla. This study used secondary data, time series rom 1975 to 2000 both national and intenational data. Econometric analyses using 2SLS was used in this study. The results are as follow: (1) the wages have negative effects on the acreage, in the shot run the acreage does not respond to wage changes; however, in the long run it does respond to wage changes; (2) the domestic prices positively affect on the yields, however, yields do not respond to price changes; (3) the previous expots affect on the current exports to Germany and the U.S., it shows that there is a cetain relationship between Indonesian expoters and German and the U.S. importers; (4) the expot pices weakly transmit to farmer level prices, moreover, intenational prices strongly transmit to the expot prices. It is shown by the absence of the effects of the expot pices on the domestic prices. Meanwhile intenational prices highly affects on the export prices; (5) the efforts to develop vanilla industry in Indonesia are concentrated on increasing quality of Indonesian vanilla, the addition of the acreage should consider the expot demand; (6) <br /><br />competitiveness of Indonesian vanilla should be maintained and improved to sustain and gain the market share.<br /><br />Key words : Vanilla, Java vanilla, Indonesia, expot, supply</p>

In many planning applications, actions can have highly diverse costs. Recent studies focus on the effects of diverse action costs on search algorithms, but not on their effects on domain-independent heuristics. In this paper, we demonstrate there are negative impacts of action cost diversity on merge-and-shrink (M&S), a successful abstraction method for producing high-quality heuristics for planning problems. We propose a new cost partitioning method for M&S to address the negative effects of diverse action costs. We investigate non-unit cost IPC domains, especially those for which diverse action costs have severe negative effects on the quality of the M&S heuristic. Our experiments demonstrate that in these domains, an additive set of M&S heuristics using the new cost partitioning method produces much more informative and effective heuristics than creating a single M&S heuristic which directly encodes diverse costs.

1 We conducted an overview and quantitative meta-analysis of all experimental literature on the protective effects of serial agitated dilutions (SADs) of toxin preparations. 2 Articles were systematically collected and evaluated for scientific quality using pre-defined methodological criteria and then independently analysed for validity. 3 We found 105 publications exploring the effects of SAD preparations in toxicological systems. 4 The quality of evidence in these studies was low with only 43% achieving one half of the maximum possible quality score and only 31 % reported in a fashion that permitted reevaluation of the data. 5 Very few studies were independently replicated using comparable models. 6 Among the high quality studies, positive effects were reported 50% more often than negative effects. 7 Four of 5 outcomes meeting quality and comparability criteria for meta-analysis showed positive effects from SAD preparations. 8 Average percent protection over controls in these preparations was 19.7 (95%Cl 6.2-33.2). 9 Further research with special attention to methodological detail and independent replicafion should be done.

SummaryTwenty patients with unresectable hepatocellular carcinoma (HCC) were followed up to 5 years after transarterial radiotherapy with 90Y-resin particles. Diagnostic radioembolizations of 99mTc-macroaggregates facilitated scintigraphic assessment of activity distribution, dose evaluation and final procedural verification. The overall survival rates were 56, 38 and 14% (after 1, 2 and 3 years, resp.). Patients with unifocal HCC and a single feeding artery (n = 7) even presented 83, 67 and 40% (2 alive after 2.75 and 4 years). With multiple arteries (n = 7), the longest survival was 26 months. Patients with multifocal HCC survived up to 33 months after selective radioembolization. Quality of life was improved in all. Survival was positively correlated with absorbed dose but residual/recurrent tumour occurred even after ≥300 Gy. Post-treatment symptoms were minimal (35 applications), pulmonary shunt rates were correctly predicted and pulmonary complications avoided.

Free-cutting steel gains specific working properties thanks to the high content of sulfur and phosphorus. These elements, especially sulfur, have a rather high tendency to segregation. Therefore, segregation defects in free-cutting steel continuously cast billets can be significantly developed. The aim of the work was to study the influence of the chemical composition of freecutting steel and casting technological parameters on the quality of the macrostructure of continuously cast billets. A metallographic assessment of the internal structure of cast metal made of free-cutting steel and data processing by application of correlation and regression analysis were the research methods. The array of production data of 43 heats of free-cutting steel of grade A12 was studied. Steel casting on a five-strand radial type continuous casting machine was carried out by various methods of metal pouring from tundish into the molds. Metal of 19 heats was poured with an open stream, and 24 heats – by a closed stream through submerged nozzles with a vertical hole. High-quality billets had a cross-sectional size of 150×150 mm. The macrostructure of high-quality square billets made of free-cutting steel of A12 grade is characterized by the presence of central porosity, axial segregation and peripheral point contamination, the degree of development of which was in the range from 1.5 to 2.0 points, segregation cracks and strips – about 1.0 points. In the course of casting with an open stream, almost all of these defects are more developed comparing with the casting by a closed stream. As a result of correlation and regression analysis, linear dependences of the development degree of segregation cracks and strips both axial and angular on the sulfur content in steel and on the ratio of manganese content to sulfur content were established. The degree of these defects development increases with growing of sulfur content in steel of A12 grade. These defects had especially strong development when sulfur content in steel was of more than 0.10%. To improve the quality of cast metal, it is necessary to have the ratio of the manganese content to the sulfur content in the metal more than eight.

The article considers the role of trust in the economy, the mechanisms of its accumulation and the possibility of using it as one of the growth factors in the future. The advantages and disadvantages of measuring the level of generalized trust using two alternative questions — about trusting people in general and trusting strangers — are analyzed. The results of the analysis of dynamics of the level of generalized trust among Russian youth, obtained within the study of the Institute for National Projects in 10 regions of Russia, are presented. It is shown that there are no significant changes in trust in people in general during the study at university. At the same time, the level of trust in strangers falls, which can negatively affect the level of trust in the country as a whole, and as a result have negative effects on the development of the economy in the future. Possible causes of the observed trends and the role of universities are discussed. Also the question about the connection between the level of education and generalized trust in countries with different quality of the institutional environment is raised.
