Two Decades Out of the Whirlpool: Past (and Possible Future) United States Interventions in Latin America [Student's Paper Series]

This paper examines the history of U.S. interventions in Latin America and attempts to explain their frequency by highlighting two factors – besides security and economic interests – that have made American interventions in Latin America so common. First, immense differences in size and influence between the United States and the States of Latin America have made interventions appear to be a low risk solution to crises that threaten American interests in the region. Second, when U.S government concerns and aspirations for Latin America converge with the general fears and aspirations of American foreign policy, interventions become much more likely. Such a convergence pushes Latin American issues high up the U.S. foreign policy agenda because of the region’s proximity to the United States and the perception that costs of intervening are low. The leads proponents of intervention to begin asking questions like “if we cannot stop communism/revolutions/drug-trafficking in Latin America, where can we stop it?” This article traces how these factors influenced the decision to intervene in Latin America during the era of Dollar Diplomacy and during the Cold War. It concludes with three possible scenarios that could lead to a reemergence of an American interventionist policy in Latin America. It makes the argument that even though the United Sates has not intervened in Latin America during the twenty-two years, it is far from clear that American interventions in Latin America will be consigned to the past.

Out of Challenge, Opportunity: Central America's Electric Sector & Key Issues and Recommendations for Enhanced Regional Electric Integration

Taken together, the six nations of Central America count a population of roughly 40 million people and an energy market equal in size to that of Colombia, sufficient to benefit from economies of scale. The region has traditionally been a net importer of hydrocarbons, and hydroelectricity has dominated electric generation. But more recently, thermoelectric generation (diesel and fuel oil) has greatly increased as a percentage of the regional generation market. Progress has been made across the region’s electric sector, beginning with reforms in the 1990s and the 1996 signing of a regional treaty aimed at the development of a regional energy integration project – the Central American Electrical Interconnection System, or SIEPAC. A fundamental SIEPAC goal is to set up a regional electric market and a regulatory system. Indeed, after many years of development, SIEPAC is poised to open a new chapter in Central America’s electric infrastructure and market. But this new era must contend with critical issues such as the need to consolidate the regional electric market, political issues surrounding the venture, and security concerns. Moreover, local conflicts, in different degrees, have become priorities for policymakers, and these are possible barriers to completing the project. The goals of the SIEPAC project and of deepening the broader electric integration process are possible if national and regional decision makers understand that cooperative decision making will produce better results than separate national decision making. Enhanced regional understanding and cooperative decision making, combined with an effort to reorient the terminology and dialogue vis-à-vis energy efficiency in Central America, form the core recommendations of this paper.

I want out of the labels : how Chuck Palahniuk's characters challenge the dominant discourse

The purpose of this study was to explore postmodern identity in the work of Chuck Palahniuk. The characters within Palahniuk's text Invisible Monsters realize the manner in which identity is a construct, and their response is to oppose and redefine it. In my research, I looked at how postmodern identity is defined by some of the leading critical thinkers in the field, and then I applied their thought to Palahniuk's characters. I showed how these characters come to understand the process by which society defines them, and with that realization, they oppose its totalizing definitions. The characters deconstruct the natural attitudes society has towards identity, and they reveal that it is in some way possible to create a unique identity that is not easily definable by the ruling discourse. I concluded that his attention to identity highlights Palahniuk's concern for the place, identity, and influence of his generation.

Out of View: Stories

OUT OF VIEW is a collection of stories set in the American Southwest about people coping with loss—the death of parents, children, ideals, innocence. The characters in this collection reap or resist lessons of life as they struggle to find their place in the world. In “First Rain,” 15-year-old Tessie struggles with the loss of her father and the demands of her mother as she navigates the rocky terrain of adolescence. In “Monsters,” middle-aged Maury has to choose between a new relationship and protecting the well-being of his 4-year-old ‘daughter.’ The stories are influenced by the Western realism of Maile Meloy and the playful plotting of Ron Carlson. These stories are inspired both by the Sonoran Desert—expansive, sun-soaked, unrepentant—and by the people who live, love, and lose in the interstices between Manifest Destiny and the Reconquista.

Mitochondrial DNA, segments I and II, its applications in population genetics and forensic sciences

The investigations of human mitochondrial DNA (mtDNA) have considerably contributed to human evolution and migration. The Middle East is considered to be an essential geographic area for human migrations out of Africa since it is located at the crossroads of Africa, and the rest of the world. United Arab Emirates (UAE) population inhabits the eastern part of Arabian Peninsula and was investigated in this study. Published data of 18 populations were included in the statistical analysis. The diversity indices showed (1) high genetic distance among African populations and (2) high genetic distance between African populations and non-African populations. Asian populations clustered together in the NJ tree between the African and European populations. MtDNA haplotypes database of the UAE population was generated. By incorporating UAE mtDNA dataset into the existing worldwide mtDNA database, UAE Forensic Laboratories will be able to analyze future mtDNA evidence in a more significant and consistent manner. ^

The clinical competency of practicing and nonpracticing faculty of associate degree schools of nursing

This study assesses and describes the perception of clinical competency and the relationship to clinical practice of full-time nursing faculty in the associate degree nursing programs in the state of Florida. The study was developed around one major hypothesis and four research questions. The Hygiene-Motivators Theory proposed by Herzberg, Mausner, and Snyderman (1959) provided the conceptual framework to explain factors that would motivate a person to expand workload and maintain job satisfaction.^ Data were collected from the 244 faculty members teaching full-time at the 15 associate degree schools of nursing accredited by the National League for Nursing in the state of Florida. A total of 186 faculty (76%) responded and 175 (72%) cases were used for data analysis.^ Two instruments were modified and combined for the investigation. The instruments were the Faculty Perception of Practice Questionnaire (Parascenzo, 1983) and a three-part Attributes Deemed Necessary for Faculty to Proclaim Clinical Competency (Smith, 1991) scale. Computer analyses employing descriptive and inferential statistics were performed.^ The findings revealed that faculty were closely divided as to practice activities with more faculty nonpracticing than practicing. Factors identified as impediments to increased clinical practice were identified as teaching load and personal/family responsibilities that lead to a lack of time and lack of opportunity. Those faculty who practice did so as moonlighters in positions that would not require advanced training. Both the practicing and nonpracticing faculty reported a high level of satisfaction with their activities as a means of maintaining clinical practice. While both groups reported a high level of expertise, those practicing faculty perceived themselves to be more clinically competent on the attributes of knowledge, skills, and on the total attribute scale. It was further revealed that perception of competency declined with the length of time spent out of practice. There was no difference in the two groups on the attributes of values/attitude. ^

Living with Uncertainty: Acting in the Best Interests of Women

A recent multi-country study on hormonal contraceptives (HC) and HIV acquisition and transmission among African HIV-serodiscordant couples reported a statistically significant doubling of risk for HIV acquisition among women as well as transmission from women to men for injectable contraceptives. Together with a prior cohort study on African women seeking health services, these data are the strongest yet to appear on the HC-HIV risk. This paper will briefly review the Heffron study strengths and relevant biological and epidemiologic evidence; address the futility of further trials; and propose instead an alternative framework for next steps. The weight of the evidence calls for a discontinuation of progestin-dominant methods. We propose here five types of productive activities: (1) scaling injectable hormones down and out of the contraceptive mix; (2) strengthening and introducing public health strategies with proven potential to reduce HIV spread; (3) providing maximal choice to reduce unplanned pregnancy, starting with quality sexuality education through to safe abortion access; (4) expanding provider training, end-user counseling and access to male and female barriers, with a special renewed focus on female condom; (5) initiating a serious research agenda to determine anti-STI/HIV potential of the contraceptive cervical cap. Trusting women to make informed choices is critical to achieve real progress in dual protection.

Joint-specific changes in locomotor complexity in the absence of muscle atrophy following incomplete spinal cord injury

ackground Following incomplete spinal cord injury (iSCI), descending drive is impaired, possibly leading to a decrease in the complexity of gait. To test the hypothesis that iSCI impairs gait coordination and decreases locomotor complexity, we collected 3D joint angle kinematics and muscle parameters of rats with a sham or an incomplete spinal cord injury. Methods 12 adult, female, Long-Evans rats, 6 sham and 6 mild-moderate T8 iSCI, were tested 4 weeks following injury. The Basso Beattie Bresnahan locomotor score was used to verify injury severity. Animals had reflective markers placed on the bony prominences of their limb joints and were filmed in 3D while walking on a treadmill. Joint angles and segment motion were analyzed quantitatively, and complexity of joint angle trajectory and overall gait were calculated using permutation entropy and principal component analysis, respectively. Following treadmill testing, the animals were euthanized and hindlimb muscles removed. Excised muscles were tested for mass, density, fiber length, pennation angle, and relaxed sarcomere length. Results Muscle parameters were similar between groups with no evidence of muscle atrophy. The animals showed overextension of the ankle, which was compensated for by a decreased range of motion at the knee. Left-right coordination was altered, leading to left and right knee movements that are entirely out of phase, with one joint moving while the other is stationary. Movement patterns remained symmetric. Permutation entropy measures indicated changes in complexity on a joint specific basis, with the largest changes at the ankle. No significant difference was seen using principal component analysis. Rats were able to achieve stable weight bearing locomotion at reasonable speeds on the treadmill despite these deficiencies. Conclusions Decrease in supraspinal control following iSCI causes a loss of complexity of ankle kinematics. This loss can be entirely due to loss of supraspinal control in the absence of muscle atrophy and may be quantified using permutation entropy. Joint-specific differences in kinematic complexity may be attributed to different sources of motor control. This work indicates the importance of the ankle for rehabilitation interventions following spinal cord injury.

Understanding the role of Dimethylsulfoniopropionate as a Potential Chemotactic Cue for Coral-Associated Bacteria

Most reef-building corals are known to engage in symbiosis not only with unicellular dinoflagellates from the genus, Symbiodinium, but they also sustain highly complex symbiotic associations with other microscopic organisms such as bacteria, fungi, and viruses. The details of these non-pathogenic interactions remain largely unclear. The impetus of this study is to gain a better understanding of the symbiotic interaction between marine bacteria and a variety of coral species representative of differing morphologies. Studies have shown that certain bacterial orders associate specifically with certain coral species, thus making the symbiotic synergy a non-random consortium. Consequently both corals and bacteria may be capable of emitting chemical cues that enables both parties to find one another and thus creating the symbiosis. One potential chemical cue could be the compound DMSP (Dimethylsulfoniopropionate) and its sulphur derivatives. Reef-building corals are believed to be the major producers of the DMSP and its derivatives during times of stress. As a result corals could potentially attract their bacterial consortium depending on their DMSP production. Corals may be able to adapt to fluctuating environmental conditions by changing their bacterial communities to that which may aid in survival. The cause of this attraction may stem from the capability of a variety of marine bacteria to catabolize DMSP into different metabolically significant pathways, which may be necessary for the survival of these mutualistic interactions. To test the hypothesis that coral-produced DMSP play a role in attracting symbiotic bacteria, this study utilized the advent of high-through sequencing paired with bacterial isolation techniques to properly characterize the microbial community in the stony coral Porites astreoides. We conducted DMSP swarming and chemotaxis assays to determine the response of these coral-associated bacterial isolates towards the DMSP compound at differing concentrations. Preliminary data from this study suggests that six out of the ten bacterial isolates are capable of conducting unidirectional motility; these six isolates are also capable of conducting swarming motility in the direction of an increasing DMSP concentration gradient. This would indicate that there is a form of positive chemotaxis on behalf of the bacteria towards the DMSP compound. By obtaining a better understanding of the dynamics that drive the associations between bacterial communities and corals, we can further aid in the protection and conservation processes for corals. Also this study would further elucidate the significance of the DMSP compound in the survival of corals under times of stress.
