When Racial Inequalities Return: Assessing the Restratification of Cuban Society 60 Years After Revolution

Few political transformations have attacked social inequalities more thoroughly than the 1959 Cuban Revolution. As the survey data in this article show, however, sixty years on, structural inequalities are returning that echo the prerevolutionary socioethnic hierarchies. While official Cuban statistics are mute about social differences along racial lines, the authors were able to conduct a unique, nationwide survey with more than one thousand respondents that shows the contrary. Amid depressed wages in the state-run economy, access to hard currency has become key. However, racialized migration patterns of the past make for highly unequal access to family remittances, and the gradual opening of private business disfavors Afro-Cubans, due to their lack of access to prerevolutionary property and startup capital. Despite the political continuity of Communist Party rule, a restructuring of Cuban society with a profound racial bias is turning back one of the proudest achievements of the revolution

The Role and Impact of Remittances on Small Business Development during Cuba’s Current Economic Reforms

This paper explores the extent to which Cuban remittance recipients are responding to the Cuban government’s current economic reforms which seek to incentivize entrepreneurial activities as an economic growth strategy and state liberalization policy. In so doing we hope to make some preliminary observations and recommendations about the potential role and impact of remittances in Cuba’s socio-economic development. It is based on an original survey conducted in Cuba in 2012

Fodder Yield of Baby Corn (\u3cem\u3eZea mays\u3c/em\u3e L.) as Influenced by Mulching, Liming and Integrated Nutrition Management under Foot Hill Condition of Nagaland

Baby corn (Zea mays L.) being one of the most important dual purpose crop is grown widely round the year for its cob as well as green fodder in India. It has an edge over the other cultivated fodder crops due to its higher production potential, wider adaptability, fast growing nature and excellent fodder quality free from toxicants. Baby corn production has been directly integrated with dairying farms in different countries because only 13-20% of fresh ear weight is used as human food and the rest (silk, husk and green stalk) can be used as excellent feed materials for milch ruminants to improve their productivity. By adopting the good agro-techniques, it is possible to produce 40-45 t/ha of fresh green fodder, which could raise a net income of Rs. 40-45×103 /ha as such it may prove to be a boon for small and marginal farmers for improving their socio-economic conditions. Hence, the mulching, liming and balanced nutrient management is the key input to ensure the higher productivity in terms of baby corn and fodder under the foot hill condition of Nagaland

BLAND HIVMÄN OCH AIDSOFFER En studie om rapporteringen kring hiv och aids i svensk dagspress

This study examines how the Swedish newspapers Dagens Nyheter and Aftonbladet report about hiv and aids. We start our analysis in the summer of 1987 when the famous designer Sigshten Herrgård reveals that he is hiv-infected, which causes a massive press coverage. To see how the reporting changes over time we compare the articles from that summer with how the epidemic was covered by the press in 1997 and 2007. Totally we have studied 355 articles. We chose the theme partly because of Torka aldrig tårar utan handskar (2012), a Swedish tv-serie about the lives and deaths of young homosexuals in Stockholm in the 80’s. It is based on a book serie written by the author and playwright Jonas Gardell who is critical to how media covered hiv and aids when it first came to Sweden. According to him the reporting was alarming and he refers to an article that described hiv as a punishment for people with an immoral lifestyle – homosexuals, prostitutes and drug addicts. We wanted to see if this really was what the reporting was like in the 80’s and what have changed since then. Our results shows that Dagens Nyheter and Aftonbladet often mention homosexuals, drug addicts and prostitutes in the reporting about hiv and aids. It is most common in 1987 but risky groups can be found in some of the articles from 1997 and 2007 as well. We can also see that the hiv-infected people very seldom get to express their view about the issue, instead it is experts, organizations and authorities that are the main actors as subjects in the reporting. We can determine that journalists often use words with a negative value in the articles about hiv and aids, such as promiscuous, non-human and reckless attitude. There has been an increasing amount of people getting hiv in Sweden, while the amount of articles in Dagens Nyheter and Aftonbladet have decreased

Particle Trapping Mechanisms in Biological Hydrogels

Understanding particle transport in hydrogels is an important step for the development of advanced drug delivery techniques. A large body of experimental research has shown that besides excluded volume effects and hydrodynamics, other nonsteric particle-gel interactions can also determine particle mobility in hydrogels. In this thesis, we aim to systematically investigate the effect of long-ranged repulsive or attractive particle-gel interactions on the particle mobility and to determine general particle diffusion mechanisms in hydrogels. For this, we present general models to simulate diffusion of particles in gels with different particle-gel interactions. First, we introduce a model for the diffusion of particles smaller than the mesh size in hydrogels with electrostatic particle-gel interactions. The gel is comprised of a spatially ordered, cubic symmetric fiber lattice. The diffusive behavior is highly charge asymmetric: Particles are slowed down more strongly by attractive than by repulsive electrostatic interactions. Furthermore, the particle mobility is highly sensitive to the ionic strength, particularly for electrostatic attraction, in agreement with experimental data. Second, we examine the effect of spatial disorder of the polymer lattice on the particle diffusive behavior. The effect of spatial disorder is linked to the presence of long-ranged particle-gel interactions. For repulsive interactions, an intermediate degree of disorder minimizes the particle mobility inside the gel but for high degrees of disorder, the diffusivity increases again. For attractive interactions, disorder slows down diffusion since particles are immobilized in regions with locally increased fiber density. A comparison between simulations with spatially disordered gels and published experimental data reveals qualitative agreement. Third, we extend our model to simulate the diffusion of particles in heterogeneous gels with mixed electrostatically attractive and repulsive interaction sites, as relevant for biological hydrogels. Mixed interaction sites are modeled with a random distribution of attractive and repulsive fiber sections. Interaction disorder, in the form of randomly mixed interaction sites, and spatial disorder have a qualitatively similar effect on the particle diffusivity. Charged particles of either sign are immobilized, since attractive particle-gel interactions determine the diffusive behavior. Qualitative agreement between simulation and experiments carried out by our collaborators from the group of Prof. Dr. DeRouchey is found. Finally, we examine the effect of hydrodynamic interactions in conjunction with long-ranged particle-gel interactions. %Agreement between simulation and experiment is improved when hydrodynamic interactions are included. Repulsive interactions decrease the effect of hydrodynamic interactions on the particle diffusivity, whereas attractive interactions increase the effect of hydrodynamic interactions, due to spatial particle-fiber correlations. With our simulations we elucidate the effects of various model features such as spatial disorder, interaction disorder and hydrodynamic interactions on the particle mobility and the detailed microscopic mechanisms governing particle diffusion in hydrogels
