The Consolidation of Social Assistance Policy in Brazil
"Brazil's trajectory in the field of income transfers is quite well known internationally. Especially after the implementation of Bolsa Familia, Brazil's experiences in the field have been the object of constant references, studies and analyses. Such experiences were even used as a foundation for a wide array of South-South cooperation initiatives. Less known, however, is that conditional cash transfers are just a part of the non-contributory social-protection system that Brazil has been developing over the past 20 years." (?)
Social Development through Efficient Policies, Evaluating the Impact of Bolsa Familia
The Brazilian welfare state has developed over time in relation to national and global trends. This study analyses the creation of Latin Americas largest Conditional Cash Transfer program in relation to these trends. The thesis provides an historical overview of the creation of Conditional Cash Transfers in the country that lastly ended with Bolsa Familia. Alongside events that led to Bolsa Familia, the nation witnessed the development of social welfare initiatives as well as alternative poverty reducing programs. The study analyses this in the context of the creation of the Brazilian welfare. The question guiding the study is: Has the Bolsa Famila programme helped to reduce poverty in Brazil? It is argued that Brazil has been successful in reducing its poverty rate as a result of the programme. The study looks deeper into the structure of Bolsa Familia in order to view its results and effects both advantages and disadvantages of the programme are assessed.

VLA stereoscopy of solar active regions. 2: Altitude, relative motion, and center-to-limb darkening of 20 centimeter emission
A newly developed method of stereoscopic correlation is applied to solar radio maps at a wavelength of 20 cm. On the basis of stereoscopic correlations between radio maps obtained on 6 different days we establish the presence of 66 radio source components associated with 22 active regions. We find the following statistical results for active region source structures at 20 cm: 1. The observed lifetime is consistent with an exponential distribution having an e-folding time scale of greater than 18 days. 2. The average altitude of 20 cm sources is 25 +/- 15 Mm; 90% of the sources are found in heights less than 40 Mm. 3. The average diameter of discrete source structures is 48 +/- 15 Mm, implying a vertical/horizontal aspect ratio of q(sub A) approx. = 0.5. 4. No significant source motion has been found with respect to the standard differential rotation rate of Omega = 13.45 deg - ((3 deg (sin(exp 2)B)). 5. We find a statistical limb darkening, which can be described by the relation (T(sub B)(alpha))/T(sub B)(0)) = 0.4 + ((0.6(cos(exp 2) alpha)) for sources with T(sub B) greater than 0.5 MK. 6. The degree of source polarization is 15% +/- 10% and is independent of source location. 7. Bright sources (greater than or approximately equal to 0.5 MK), or equivalently, long-lived sources (greater than or approximately equal to 5 days) show a systematic variation of their altitude as function of the center-limb distance.
