Questioning Appropriation: Agency and Complicity in a Transnational Feminist Location Politics

In feminist circles agency is often opposed to complicity and associated with resistance to sexism and patriarchy, yet such binary oppositions make the political stakes of their presumed boundaries difficult to interrogate. By bringing location politics into dialogue with agency theory, boundaries of same/Other and location categories may move from a naturalized ground for political work to the contested center of a politics of resistance. I follow a Foucauldian interpretation of agency to reconsider the ethico-politics of established divisions of self and Other both individually and in terms of social movements. By following Gayatri Spivak, Meyda Yeğenoğlu, and Chandra Mohanty\u27s transnational feminist politics, I argue for the refusal of totalizing binaries and for careful attention to unavoidable complicities. This makes possible practices of agency that can critique the political and ethical limits and effects of its epistemology and take as its central project the intervention into appropriations of the Others into modern notions of the real. The resulting reconstitution of self-Other relations in their work opens up important new avenues for building social movements that acknowledge difference within the subject or the movement rather than deny and expel their Others

Subjugated Knowledges and Dedisciplinarity in Cultural Studies Pedagogy

Discussions of the contested politics of academic fields that have emerged from social movements often emphasize course content while deemphasizing the ways that power circulates through specific sites in the academy. Certainly women\u27s studies, queer studies, and the different ethnic studies fields have struggled to maintain links to the social movements that engendered them. and a concomitant focus on social change. In a more complex fashion, the same is true of postcolonial studies. Similarly, cultural studies may be understood as an academic field emerging from class-based social movements that are affiliated in complex ways with various Marxist analyses whose academic lineage is longer and differently constituted. Within and among these different fields, ongoing debates continue over their ability to remain oriented toward social justice in the face of pressures from the academy to align with knowledge protocols and modes of claiming legitimacy that are measured in terms distant from those of progressive social change

An Ethico-Politics of Subaltern Representations in Post-9/11 Documentary Film

The World War Without End (WWWoE), formerly known as the War on Terror,ii is one of those rare occasions when a gendered subaltern population comes to the attention of the nation-state. If the subaltern is understood as something akin to illiterate rural women from the global South, then she now has the full attention of the White House and Downing Street, the US State Department, CNN and Time magazine.iii In official state positions and in media coverage, interest in the subaltern is often expressed in humanitarian attention to the rights or freedoms of these subaltern women in order to justify military invasion and ongoing interventio

Extreme Spacecraft Charging in Polar Low Earth Orbit

Spacecraft in low altitude, high inclination (including sun -synchronous) orbits are widely used for remote sensing of the Earth fs land surface and oceans, monitoring weather and climate, communications, scientific studies of the upper atmosphere and ionosphere, and a variety of other scientific, commercial, and military applications. These systems episodically charge to frame potentials in the kilovolt range when exposed to space weather environments characterized by a high flux of energetic (approx.10 fs kilovolt) electrons in regions of low background plasma density. Auroral charging conditions are similar in some ways to the space weather conditions in geostationary orbit responsible for spacecraft charging to kilovolt levels. We first review the physics of space environment interactions with spacecraft materials that control auroral charging rates and the anticipated maximum potentials that should be observed on spacecraft surfaces during disturbed space weather conditions. We then describe how the theoretical values compare to the observational history of extreme charging in auroral environments. Finally, a set of extreme DMSP charging events are described varying in maximum negative frame potential from approx.0.6 kV to approx.2 kV, focusing on the characteristics of the charging events that are of importance both to the space system designer and to spacecraft operators. The goal of the presentation is to bridge the gap between scientific studies of auroral charging and the need for engineering teams to understand how space weather impacts both spacecraft design and operations for vehicles on orbital trajectories that traverse auroral charging environments

Measuring Actual Behaviors in HCI Research – A call to Action and an Example

There have been repeated calls for studies in behavioral science and human-computer interaction (HCI) research to measure participants’ actual behaviors. HCI research studies often use multiple constructs as perceived measures of behavior, which are captured using participants’ self-reports on surveys. Response biases, however, are a widespread threat to the validity of self-report measures. To mitigate this threat to validity, we propose that studies in HCI measure actual behaviors in appropriate contexts rather than solely perceptions. We report an example of using movements that reflect both actual behavior and behavioral changes measured within a health care IS usage context, specifically the detection and alleviation of neuromuscular degenerative disease. We propose and test a method of monitoring mouse-cursor movements to detect hand tremors in real time when individuals are using websites. Our work suggests that analyzing hand movements as an actual (rather than perceptual) measure of usage could enrich other areas of IS research (e.g., technology acceptance, efficacy, fear, etc.), in which perceptions of states and behavior are measured post hoc to the interaction and subject to the threats of various forms of response bias

Are people mindful in different ways? Disentangling the quantity and quality of mindfulness in latent profiles and exploring their links to mental health and life effectiveness

We sought to disambiguate the quantitative and qualitative components of mindfulness profiles, examine whether including ‘nonattachment’ as a subcomponent of mindfulness alters the profiles, and evaluate the extent to which the person‐centred approach to understanding mindfulness adds predictive power beyond a more parsimonious variable‐centred approach. Using data from a nationally representative sample of Americans (N = 7884; 52% female; Age: M = 47.9, SD = 16), we utilized bifactor exploratory structural equation modelling and latent profile analysis to separate the level and shape of previously identified profiles of mindfulness (Pearson, Lawless, Brown, & Bravo, 2015). Consistent with past research, we identified a judgmentally observing profile and a non‐judgmentally aware group, but inconsistent with past research, we did not find profiles that showed high or low levels on all specific aspects of mindfulness. Adding nonattachment did not alter the shape of the profiles. Profile membership was meaningfully related to demographic variables. In models testing the distinctive predictive utility of the profiles, the judgmentally observing profile, compared to the other profiles, showed the highest levels of mental ill‐health, but also the highest levels of life satisfaction and effectiveness. We discuss the implications of our study for clinical interventions and understanding the varieties of mindfulnes

Measuring and Correcting Wind-Induced Pointing Errors of the Green Bank Telescope Using an Optical Quadrant Detector

Wind-induced pointing errors are a serious concern for large-aperture high-frequency radio telescopes. In this paper, we describe the implementation of an optical quadrant detector instrument that can detect and provide a correction signal for wind-induced pointing errors on the 100m diameter Green Bank Telescope (GBT). The instrument was calibrated using a combination of astronomical measurements and metrology. We find that the main wind-induced pointing errors on time scales of minutes are caused by the feedarm being blown along the direction of the wind vector. We also find that wind-induced structural excitation is virtually non-existent. We have implemented offline software to apply pointing corrections to the data from imaging instruments such as the MUSTANG 3.3 mm bolometer array, which can recover ~70% of sensitivity lost due to wind-induced pointing errors. We have also performed preliminary tests that show great promise for correcting these pointing errors in real-time using the telescope's subreflector servo system in combination with the quadrant detector signal.Comment: 17 pages, 11 figures; accepted for publication in PAS
