title: Expanding the context for student learning of science: The conceptual development of the New Zealand Science Learning Hub

authors: Jones, Alister

subjects: New Zealand

abstract: Student engagement in science is an issue of international concern. Research indicates that one way to increase engagement in science is to involve students in authentic and relevant contexts that promote an enquiry-based stance. A key aspect to engaging students is to provide teachers with educative materials. In today’s world teachers and students look to web-based materials for their own development and learning. This paper will provide a conceptual framework for the development of the New Zealand Science Learning Hub as well as describing the process of its development, its component parts and their relationship to the conceptual frame.

title: The impact of immigration on international trade: a meta‐analysis

authors: Genc, Murat

subjects: international trade

abstract: Since the early 1990s many studies have been conducted on the impact of international migration on international trade, predominantly from the host country perspective. Because most studies have adopted broadly the same specification, namely a log‐linear gravity model of export and import flows augmented with the logarithm of the stock of immigrants from specific source countries as an additional explanatory variable, the resulting elasticities are broadly comparable and yield a set of estimates that is well suited to meta‐analysis. We therefore compile and analyze in this paper the distribution of immigration elasticities of imports and exports across 48 studies that yielded 300 estimates. The results confirm that immigration boosts trade, but its impact is lower on trade in homogeneous goods. An increase in the number of immigrants by 10 percent increases the volume of trade by about 1‐2 percent The migrant elasticity of imports is on average similar to that of exports. The estimates are affected by the choice of some covariates, the nature of the data (cross‐section or panel) and the estimation technique.  Elasticities vary between countries in ways that cannot be explained by study characteristics; host country differences in immigration policies do apparently matter for the trade impact. The trade‐enhancing impact of migration appears to be greater for migration between countries of different levels of development than between developed countries.
