As the old model of study abroad welcomes a new generation of student, administrators are forced to grapple with how and whether to adapt the old model to new communication technologies. Assumed in the traditional model of study abroad, and in the cultural and language learning theories around which those programs were constructed, is that learning takes place in face-to-face (FTF) encounters with the host culture. Under these assumptions, the Internet is merely a distraction and ought to be avoided during study abroad. However, more recent research on Internet-mediated communication no longer situates Internet-mediated communication as diametrically opposed to FTF communication. Study abroad participants and administrators have long grappled with how to decrease stress and increase integration during study abroad. Literature on Internet-mediated social support, and computer-mediated communication, suggests that the Internet may be an effective means through which to access socially supportive peer networ...

Children who experience poor nutrition during the first 1000 days of life are more vulnerable to illness and death in the near term, as well as to lower work capacity and productivity as adults. These problems motivate research to identify basic and underlying factors that influence risks of child malnutrition. Based on a structured search of existing literature, we identified 90 studies that used statistical analyses to assess relationships between potential factors and major indicators of child malnutrition: stunting, wasting, and underweight. Our review determined that wasting, a measure of acute malnutrition, is substantially understudied compared to the other indicators. We summarize the evidence about relationships between child malnutrition and numerous factors at the individual, household, region/community, and country levels. Our results identify only select relationships that are statistically significant, with consistent signs, across multiple studies. Among the consistent predictors of child malnutrition are shocks due to variations in climate conditions (as measured with indicators of temperature, rainfall, and vegetation) and violent conflict. Limited research has been conducted on the relationship between violent conflict and wasting. Improved understanding of the variables associated with child malnutrition will aid advances in predictive modeling of the risks and severity of malnutrition crises and enhance the effectiveness of responses by the development and humanitarian communities.
