This study compares life stressors and school outcomes among newcomer immigrant adolescents from Latin America, Asia, and the Caribbean. Participants attended a predominantly low-income, urban international public high school in the northeast. The Latina/o students were exposed to more life stressors and had lower attendance and achievement than non-Latina/o students. Life stressors mediated the relationship between ethnicity and academic outcomes. Results deepen experts’ understanding of the achievement gap, suggesting that newcomer immigrant adolescents from Latin America face unique risks and deserve intervention efforts focused on sociocontextual stressors that may prevent these students from achieving their full academic potential. 相似文献

In the double rank analysis of research publications, the local rank position of a country or institution publication is expressed as a function of the world rank position. Excluding some highly or lowly cited publications, the double rank plot fits well with a power law, which can be explained because citations for local and world publications follow lognormal distributions. We report here that the distribution of the number of country or institution publications in world percentiles is a double rank distribution that can be fitted to a power law. Only the data points in high percentiles deviate from it when the local and world μ parameters of the lognormal distributions are very different. The likelihood of publishing very highly cited papers can be calculated from the power law that can be fitted either to the upper tail of the citation distribution or to the percentile-based double rank distribution. The great advantage of the latter method is that it has universal application, because it is based on all publications and not just on highly cited publications. Furthermore, this method extends the application of the well-established percentile approach to very low percentiles where breakthroughs are reported but paper counts cannot be performed. 相似文献

Many findings from research as well as reports from teachers describe students’ problem solving strategies as manipulation
of formulas by rote. The resulting dissatisfaction with quantitative physical textbook problems seems to influence the attitude
towards the role of mathematics in physics education in general. Mathematics is often seen as a tool for calculation which
hinders a conceptual understanding of physical principles. However, the role of mathematics cannot be reduced to this technical
aspect. Hence, instead of putting mathematics away we delve into the nature of physical science to reveal the strong conceptual
relationship between mathematics and physics. Moreover, we suggest that, for both prospective teaching and further research,
a focus on deeply exploring such interdependency can significantly improve the understanding of physics. To provide a suitable
basis, we develop a new model which can be used for analysing different levels of mathematical reasoning within physics. It
is also a guideline for shifting the attention from technical to structural mathematical skills while teaching physics. We
demonstrate its applicability for analysing physical-mathematical reasoning processes with an example. 相似文献

During natural disasters, mass media facilitate the timely provision of accurate information about health risks to the public. This study informs our understanding of such public health discourse, utilizing a content-analysis of 235 newspaper articles in four major metropolitan newspapers published in the five weeks after Hurricane Katrina hit the Gulf Coast in August 2005. These data reveal that a small and diminishing number of articles included public health information over time, detailed the hurricane impact on affected communities, and used reliable health sources. The implications for future research from a public health and media relations perspective are discussed. 相似文献
