It's not queer to be gay: Miami and the emergence of the gay rights movement, 1945–1995

This work chronicles how queer individuals politicized their same-sex desires from the post-World War II era to the mid-1990s. Using Miami as a site of exploration, this work demonstrates the shift from understanding homosexuality as a same-sex "desire" to a distinct form of "civil rights." It argues that by no means was it inevitable that queer issues entered the American political mainstream. This project pays particular attention to Miami's Cuban exile community, as it managed to garner great socio-political power in the city. Like others in the city's power structure, Miami's Cuban exiles were also fundamentally traditionalists. Together, these phenomena crystallized into a matrix of obstacles that stunted the growth of the gay rights movement. This work demonstrates the historical dynamics of sexuality and politics by contextualizing immigration, ethnicity, race, consumerism, and Cold War domestic and foreign policy.

The role of contingency and gaze direction in the emergence of social referencing

The current study assessed the importance of infant detection of contingency and head and eye gaze direction in the emergence of social referencing. Five- to six-month-old infants' detection of affect-object relations and subsequent manual preferences for objects paired with positive expressions were assessed. In particular, the role of contingency between toys' movements and an actress's emotional expressions as well as the role of gaze direction toward the toys' location were examined. Infants were habituated to alternating films of two toys each paired with an actress's affective expression (happy and fearful) under contingent or noncontingent and gaze congruent or gaze incongruent conditions. Results indicated that gaze congruence and contingency between toys' movements and a person's affective expressions were important for infant perception of affect-object relations. Furthermore, infant perception of the relation between affective expressions and toys translated to their manual preferences for the 3-dimensional toys. Infants who received contingent affective responses to the movements of the toys spent more time touching the toy that was previously paired with the positive expression. These findings demonstrate the role of contingency and gaze direction in the emergence of social referencing in the first half year of life.^

The Re-Emergence of Suriname’s Désiré (Desi) Bouterse: Political Acumen and Geopolitical Anxiety

This study examines some concerns that derive from Suriname‘s May-July 2010 elections, which resulted in the re-emergence of erstwhile military ruler and convicted drug trafficker, Désiré (Desi) Bouterse, as President of the Republic. The victory reflects Bouterse‘s political acumen in aggregating disparate political interests and in establishing a viable coalition government. But because of his history and profile, this triumph has generated anxiety in some places internationally. In this respect, the study examines anxieties related to three matters: (a) relations with Guyana, where there is an existing territorial dispute and a recently resolved maritime dispute, (b) illegal drug trafficking operations, and (c) foreign policy engagement with Venezuela. There has been a flurry of bilateral activities—including several presidential summits—with Guyana since President Bouterse‘s inauguration, albeit seemingly more about symbolism than substance. Although the maritime dispute was settled by a Tribunal of the United Nations Convention of the Law of the Sea in 2007, the 15,000 km2 New River Triangle is still unresolved. Indeed, in June 2011 President Bouterse reasserted Suriname‘s claim to the Triangle. Suriname has upped the ante in that dispute by portraying internationally the map of Suriname as inclusive of the disputed area. In all likelihood that self-redefinition slowly will become the country‘s cartographic definition in the eyes of the world if Guyana does not successfully rebuff that move or pursue the definitive settlement of the dispute. A geonarcotics assessment shows Suriname to be still heavily implicated in trafficking, because of geography, law enforcement limitations, corruption, and other factors. But despite Bouterse‘s drug-related history and that of former senior military officers, several reasons suggest the inexpediency of a narco-state being created by Bouterse. As well, as part of Suriname‘s pursuit of increased Caribbean and South American engagement, it has boosted relations with Venezuela, which has included it in PetroCaribe and provided housing and agricultural aid. However, the engagement appears to be driven more by pragmatism and less by any ideological affinity with Hugo Chavez.

Emergence and Fate of Siloxanes in Waste Streams: Release Mechanisms, Partitioning and Persistence in Three Environmental Compartments

Siloxanes are widely used in personal care and industrial products due to their low surface tension, thermal stability, antimicrobial and hydrophobic properties, among other characteristics. Volatile methyl siloxanes (VMS) have been detected both in landfill gas and biogas from anaerobic digesters at wastewater treatment plants. As a result, they are released to gas phase during waste decomposition and wastewater treatment. During transformation processes of digester or landfill gas to energy, siloxanes are converted to silicon oxides, leaving abrasive deposits on engine components. These deposits cause increased maintenance costs and in some cases complete engine overhauls become necessary. The objectives of this study were to compare the VMS types and levels present in biogas generated in the anaerobic digesters and landfills and evaluate the energetics of siloxane transformations under anaerobic conditions. Siloxane emissions, resulting from disposal of silicone-based materials, are expected to increase by 29% within the next 10 years. Estimated concentrations and the risk factors of exposure to siloxanes were evaluated based on the initial concentrations, partitioning characteristics and persistence. It was determined that D4 has the highest risk factor associated to bioaccumulation in liquid and solid phase, whereas D5 was highest in gas phase. Additionally, as siloxanes are combusted, the particle size range causes them to be potentially hazardous to human health. When inhaled, they may affix onto the alveoli of the lungs and may lead to development of silicosis. Siloxane-based COD-loading was evaluated and determined to be an insignificant factor concerning COD limits in wastewater. Removal of siloxane compounds is recommended prior to land application of biosolids or combustion of biogas. A comparison of estimated costs was made between maintenance practices for removal of siloxane deposits and installation/operation of fixed-bed carbon absorption systems. In the majority of cases, the installation of fixed-bed adsorption systems would not be a feasible option for the sole purpose of siloxane removal. However they may be utilized to remove additional compounds simultaneously.

The emergence of a mass community-based ecotourism theme park : the case of Ejido Chacchoben, Quintana Roo, Mexico

In 1998, a dispute between a federal government agency and the local community of Chacchoben resulted in the emergence of a community-based ecotourism (CBE) enterprise to be fully owned and operated by the community in conjunction with a complex arrangement of agreements and partnerships with external actors. CBE is usually framed as a lower-impact, often small-scale alternative to mass tourism and as a conservation and development strategy that can hypothetically protect biologically diverse landscapes while improving the lives of marginalized peasant and indigenous communities through their participation. This case study analyzes the roles of common property land tenure and social capital and how the unique dilemma of a mass community-based ecotourism theme park emerged in Chacchoben. Findings indicate that local decisions and processes of development, conservation, and land use are affected by the complex interaction between local and external institutions and fluctuating levels of social capital.
