ABSTRACT
ABSTRACT: Kazakhstan is located in the hinterland of Central Asia. Its virtuous geographical advantages and huge grain production potential make it one of the most important grain exporters in the world. The research on the problem of the grain trade in Kazakhstan is of great significance for food security. This study measured its international competitiveness using the International Market Share Index, the Revealed Comparative Advantage Index, Trade competitiveness index and calculated the international competitiveness and analyzed the influencing factors of grain export by constructing an extended gravity model and measured its export potential. Results showed that Kazakhstan has a low share of the international grain market; however, wheat, barley, and buckwheat have strong export advantages; the level of economic development and economic distance has significantly promoted the scale of grain exports. While geographical distance, the difference in GDP per capita, and the fact whether trading partner countries have joined the Eurasian Economic Union have caused obstacles to grain exports. Kazakhstan's export potential to 6 countries including Russia, Kyrgyzstan and China shows an upward" trend, its export potential to 6 countries including Tajikistan and Ukraine showing a "stable" trend, and its export to 9 countries included Poland and Germany. The potential showed a "declining" trend.
RESUMO: O Cazaquistão está localizado no interior da Ásia Central. Suas virtuosas vantagens geográficas e grande potencial de produção de grãos a tornam um dos exportadores de grãos mais importantes do mundo. A pesquisa sobre o problema do comércio de grãos no Cazaquistão é de grande importância para a segurança alimentar. Este estudo mede sua competitividade internacional por meio do índice IMS, índice RCA, índice TC e calcula a competitividade internacional e analisa os fatores influenciadores da exportação de grãos por meio da construção de um modelo gravimétrico estendido e mede seu potencial exportador. Os resultados mostram que o Cazaquistão tem uma baixa participação no mercado internacional de grãos; no entanto, trigo, cevada e trigo sarraceno têm fortes vantagens de exportação; o nível de desenvolvimento econômico e a distância econômica têm promovido significativamente a escala das exportações de grãos. Embora a distância geográfica, a diferença no PIB per capita e o fato de os países parceiros comerciais terem aderido à União Econômica da Eurásia têm causado obstáculos às exportações de grãos. O potencial de exportação do Cazaquistão para seis países, incluindo Rússia, Quirguistão e China mostra uma tendência de "alta", seu potencial de exportação para seis países, incluindo Tajiquistão e Ucrânia, mostra uma tendência" estável "e sua exportação para nove países, incluindo Polônia e Alemanha. O potencial mostra uma tendência de "declínio".
ABSTRACT
Objective@#To explore the hot issues and developing trend of the research of campus bulling,and to provide a reference for the research on campus bullying.@*Methods@#The power of research, high-impact authors, highly cited journals, high-frequency keywords, and burst terms related to school bullying from the Web of Science database were analyzed using CiteSpace software. The data collection time was May 9, 2018.@*Results@#A total of 3 561 literature data were obtained. The results showed that the country with the highest number of publications was the United States; England had the highest centrality and was in a critical position in the research. The University of Turku in Finland was the core research institution. Salmivalli C was the author of the highest publication, Olweus D was the most frequent cited author. The high-impact journal was Aggressive Behavior. In terms of high-frequency keywords, the core vocabulary such as bully, adolescence, and victim were listed. Middle school students were the most frequently studied; in the form of bullying, the frequency of violence, aggression, and cyberbully was more common; depression, mental health and health appeared more frequently in terms of bullying outcomes. Mutant words including school children, bullying, victimization, relational aggression were more common.@*Conclusion@#The research hotspots on campus bullying during the past decade include violence, gender, social support, and mental health. Bullying among college students will be a hot research topic in the future. Continued efforts should be carried out in the field of campus bullying in China.
