There are some parameters of economic analysis in specialized papers that barely have incorporated the importance of the economic activity expansion over the geographical scale, no matter in medium, largest or metropolitan cities. We present evidence and hypothesis on the urban nature of economic expansion that might be able to combine the use of concentric and polycentric structure in a city with a population over 300 thousands people. The paper is developed in two main aspects of economic expansion: 1) the nature of the employment that consolidates and structures the labor market; and 2) the organization of intraurban space that is stimulated by those activities.

H-2A visas for temporary agricultural workers are very controversial, with farm-workers supporters claiming that it does not provide sufficient protections for US workers and leaves foreign workers open to abuse and exploitation. Tamaulipas presents a long tradition of rural migration to the United States in search of farm employment. The preference of US employers for Tamaulipas' workers owes to the proximity of this state to the frontier, which lowers transportation costs, and the experience of Tamaulipas' workers in very demanding activities, like orange picking. This paper analyses the level of compliance of labor contracts of Tamaulipas workers employed in the United States in the farming sector with H-2A visas. [ABSTRACT FROM AUTHOR]

Reproductive health services supplied by medical institutions to women in two border cities one in Mexico and another in the United States (Matamoros, Tamaulipas, and Brownsville, Texas) arc comparatively analysed. This paper is based on survey interviews on the supply side (hospital and clinics) and on the demand side of health services (patients). Concerning Brownsville, institutions supply a wide range of maternity services to women who behave very carefully in relation to their pregnancy and demand more specialised personnel. Regarding Matamoros, despite of the fact that local medical institutions supply a higher specialisation of medical and auxiliary personnel to women, as well is an integral attention, the use of these services is required by Mexican women at the last trimester of the pregnancy, and these services lend to be less specialised than in Brownsville.
