Two Decades of Imperial Failure: Theorizing U.S. Regime Change Efforts in Venezuela from Bush II to Trump

Former Venezuelan President Hugo Chávez ushered in the Pink Tide and the rise of the left in Latin America at the turn of the 21st century. Chávez initially won presidential elections in 1998 based on the promise of participatory democracy and tackling economic inequality, and thereafter by championing 21st Century Socialism. From the beginning, Chávez challenged U.S. global leadership by condemning its vision for the world and by cultivating an anti-imperial nexus of allies. This pattern has continued under current President Nicolás Maduro. In response, the U.S. has opposed the Venezuelan socialists throughout three successive presidential administrations: Bush II, Obama, and Trump. Taking influence from Michael Mann’s IEMP model of social power, we detail the ideological, economic, military, and political strategies these administrations have used to undermine the Venezuelan government and assist right-wing opposition parties and civil society groups in Venezuela. While Bush II and Obama primarily sought to depose Chávez by bolstering right-wing political parties and groups that aimed to unseat Chávez at the ballot box, Trump has recognized a parallel government open to an extra-legal change of government and openly called for coercive regime change through a military coup d’état

Latitudinal dependence of wind-induced near-inertial energy

Mid-latitude storms, accounting for the majority of wind energy input to near-inertial motions in the ocean, are known to shift their track significantly from one year to another. The consequence of such storm track shifts on wind-induced near-inertial energy (NIE) is yet unknown. Here, the latitudinal dependence of wind-induced NIE is first analysed in the framework of the slab model and then tested using two numerical ocean models. It is found that the NIE input by pure inertial wind stress forcing, which dominates the wind energy input to near-inertial motions, is independent of latitude. As a consequence, the NIE generated by white-noise wind stress forcing is also latitudinally independent. In contrast, the NIE generated by red-noise wind stress forcing shows strong dependence on latitude owing to longer inertial periods at lower latitudes capable of sampling greater inertial wind stress forcing. Given that the observed surface wind stress spectra are red, results from this study suggest that an equatorward shift of the storm track is likely to result in an increase in wind-induced NIE in the ocean, while the opposite is true for a poleward shift

PDAS as workplace tools for science teachers

This paper reports on work in progress on a project investigating the use of personal digital assistants (PDAs) to help students make use of knowledge gained during the study of a Masters course in science education in their professional practice. We report on a review of the literature on mobile technologies as learning tools in workplace settings. We analyse this literature to suggest possible hypotheses for our study. We also describe the selection and design of activities for use on the PDAs, the evaluation strategy based on an activity theory augmented approach for the project and the issues arising during the project

Long-term conditions, self-management and systems of support::An exploration of health beliefs and practices within the Sikh community, Birmingham, UK

Objective. The global prevalence of non-communicable diseases (NCDs), such as diabetes mellitus and coronary heart disease, continues to rise. Internationally, people of South Asian origin (i.e. by birth or heritage) are much more likely to develop and live with NCDs compared to the general population. The South Asian diaspora population is highly heterogeneous, varying by socioeconomic status, migration history, religion and ethnicity. This article reports the findings of a study to explore the types of support accessed by Punjabi Sikhs living in Birmingham and the Black Country, UK, who were living with NCDs. Design. The study sought to develop a greater understanding of past experiences of accessing support and the importance of relationships in the mobilisation of resources for self-management. It was nested within a larger programme of research which explored attitudes to prevention of chronic diseases in local communities in the region. Seventeen Punjabi Sikh men and women were recruited through purposive sampling. Narrative interviews were conducted and analysed by the research team. Sociological theories on systems of support and social relations were consulted to inform the interpretation of data. Results. The study findings suggest that participants interpreted chronic disease self-management in relation to four primary systems of support: health services for disease management; multiple sources of care, including traditional Indian medicines and the Internet, for symptom management; community groups for lifestyle management; and the family for emotional and physical care. Within these systems of support, participants identified barriers and facilitators to the maintenance of a healthy lifestyle. We focus on intra-group diversity; exploring the intersection of views and experiences by age, gender, generation and caste. Conclusion. The findings have implications for the design and delivery of primary care and community services which support the prevention and management of NCDs in an increasingly diverse population

Methodological challenges of cross-language qualitative research with South Asian communities living in the UK

Objective: We investigate (1) the influence of ethnic, gender, and age concordance with interviewers and (2) how expression of qualitative data varies between interviews delivered in English and community languages (Punjabi/Urdu) with monolingual and bilingual participants across three generations of the Indian Sikh and Pakistani Muslim communities living in the UK. Methods: We analyzed and interpreted semi-structured interview transcripts that were designed to collect data about lifestyles, disease management, community practices/beliefs, and social networks. First, qualitative content analysis was applied to transcripts. Second, a framework was applied as a guide to identify cross-language illustrations where responses varied in length, expression and depth. Results: Participant responses differed by language and topic. First-generation migrants when discussing religion, culture, or family practice were far likelier to use group or community narratives and give a longer response, indicating familiarity with or importance of such issues. Ethnic and gender concordance generated greater rapport between researchers and participants centered on community values and practices. Further, open-ended questions that were less direct were better suited for first-generation migrants. Conclusion: Community-based researchers need more time to complete interviews in second languages, need to acknowledge that narratives can be contextualized in both personal and community views, and reframe questions that may lead to greater expression. Furthermore, we detail a number of recommendations with regard to validating the translation of interviews from community languages to English as well as measures for testing language proficiency

Applications of Automata and Graphs: Labeling-Operators in Hilbert Space I

We show that certain representations of graphs by operators on Hilbert space have uses in signal processing and in symbolic dynamics. Our main result is that graphs built on automata have fractal characteristics. We make this precise with the use of Representation Theory and of Spectral Theory of a certain family of Hecke operators. Let G be a directed graph. We begin by building the graph groupoid G induced by G, and representations of G. Our main application is to the groupoids defined from automata. By assigning weights to the edges of a fixed graph G, we give conditions for G to acquire fractal-like properties, and hence we can have fractaloids or G-fractals. Our standing assumption on G is that it is locally finite and connected, and our labeling of G is determined by the "out-degrees of vertices". From our labeling, we arrive at a family of Hecke-type operators whose spectrum is computed. As applications, we are able to build representations by operators on Hilbert spaces (including the Hecke operators); and we further show that automata built on a finite alphabet generate fractaloids. Our Hecke-type operators, or labeling operators, come from an amalgamated free probability construction, and we compute the corresponding amalgamated free moments. We show that the free moments are completely determined by certain scalar-valued functions.Comment: 69 page

X-Ray Scattering Measurements of the Transient Structure of a Driven Charge-Density-Wave

We report time-resolved x-ray scattering measurements of the transient structural response of the sliding {\bf Q}$_{1}$ charge-density-wave (CDW) in NbSe$_{3}$ to a reversal of the driving electric field. The observed time scale characterizing this response at 70K varies from $\sim$ 15 msec for driving fields near threshold to $\sim$ 2 msec for fields well above threshold. The position and time-dependent strain of the CDW is analyzed in terms of a phenomenological equation of motion for the phase of the CDW order parameter. The value of the damping constant, $\gamma = (3.2 \pm 0.7) \times 10^{-19}$ eV $\cdot$ seconds $\cdot$ \AA$^{-3}$, is in excellent agreement with the value determined from transport measurements. As the driving field approaches threshold from above, the line shape becomes bimodal, suggesting that the CDW does not depin throughout the entire sample at one well-defined voltage.Comment: revtex 3.0, 7 figure
