Interregionalism's impact on regional integration in developing countries: the case of Mercosur

This article examines the impact of interregionalism on deepening regional integration processes in non-European Union (EU) regions, specifically the Southern Common Market (Mercosur). It considers whether ‘capacity-building’ functions of interregionalism are present in EU–Mercosur relations. It argues that although negotiations for an association agreement might have helped Mercosur survive periods of severe crisis in the past, the terms of the agreement under negotiation were not sufficiently attractive to encourage deeper integration in Mercosur. Moreover, interregionalism cannot be expected to compensate for low institutionalization, nor substitute for weak political willingness to deepen integration. Ultimately, Mercosur alone can decide how far it wants to take its regional integration

Mañana today: a long view of economic value creation in Latin America

This commentary concerns the significant opportunities which the global economy’s current nearshoring trend offers the Latin American and Caribbean (LAC) region owing to a US–China decoupling. Yet the region, generally, is woefully unprepared. The state of the LAC will make or break the peoples’ attempts to exploit the new potential to better themselves. Yet the short-termist myopia and public policy neglect of politicians is the greatest obstacle to the kind of development the region needs the most: high-quality FDI enabling educated innovators to push LAC up the rank of global value chains; or else it will be trapped in middle income, at best

Collection and short-term preservation of semen from free-ranging eastern grey kangaroos (Macropus giganteus: Macropodidae)

OBJECTIVES: To evaluate electro-ejaculation of free-range eastern grey kangaroos in the field and assess the efficacy of four diluents to preserve sperm motility over a 48-h period at 5 degrees C. PROCEDURE AND DESIGN: Under gaseous anaesthesia, 25 free-range kangaroos were electro-ejaculated and characteristics of the ejaculate noted. Spermatozoa obtained from eight ejaculates were diluted in phosphate buffered saline containing various combinations of egg yolk and glucose and refrigerated at 5 degrees C for 48 h. RESULTS: Spermatozoa were recovered from 24 of 28 ejaculates. Mean (+/- SEM) semen volume (mL) and pH were 25.0 +/- 1.9 and 7.1 +/- 0.1 respectively. The forward motility (%), rate of movement of sperm (0 to 5) and sperm concentration (x 10(6)/mL) were 77.4 +/- 1.5, 3.8 +/- 0.9 and 31.2 +/- 7.3 respectively. There was no significant difference between the four diluents in their ability to maintain forward motility of spermatozoa over 48 h. However, rate of movement over the same period was significantly (P < 0.01) improved when sperm were diluted in phosphate buffered saline containing 10% egg yolk. CONCLUSIONS: Electro-ejaculation is a safe and reliable method for collecting semen from free-ranging eastern grey kangaroos. Preliminary attempts at short-term preservation showed that the motility of kangaroo spermatozoa could be adequately stored for 24 h and that the addition of egg yolk to the semen diluent was beneficial for improving the rate of sperm movement
