If you look at a rendering of planet Earth from a bird's eye view, you will see satellites orbiting the planet like electrons, each one a testament to humanity's expansion beyond Earth's atmosphere. It begs the question: what is this new humanized landscape? The dominant voice that has attempted to answer this question is the realist one, which has led the charge of academic inquiry into outer space since the fateful launch of the Sputnik in 1957. Though enlightening in some respects, the realist perspective oftentimes obscures the heterogeneous complexity of the actors, actions, limits and possibilities that have constructed this very humanized outer space. This paper looks at the humanization of outer space through the lens of JASON-3, an internationally collaborative satellite designed primarily to measure the topography of the Earth's oceans. A vast number of actors collaborated to enact the network that created JASON-3, including bureaucratic agencies, academics, private contractors, political bodies, other satellites, the sun and even gravity. This paper will focus on these actors and the work that they did to form the network, showing a glimpse of the entangled connections that eventually produced JASON-3. Through telling this story, I argue: (1) outer space is more complex than state-level relations and (2) critical geography -- with its insight into relational spaces and deconstructing power structures -- has a unique place to fill in outer space literature.

ABSTRACTThis paper models maximum entropy configurations of idealized gravitational ring systems. Such configurations are of interest because systems generally evolve toward an ultimate state of maximum randomness. For simplicity, attention is confined to ultimate states for which interparticle interactions are no longer of first order importance. The planets, in their orbits about the sun, are one example of such a ring system. The extent to which the present approximation yields insight into ring systems such as Saturn's is explored briefly.

Galileo Unbound: A Path Across Life, The Universe and Everything traces the journey that brought us from Galileo’s law of free fall to today’s geneticists measuring evolutionary drift, entangled quantum particles moving among many worlds, and our lives as trajectories traversing a health space with thousands of dimensions. Remarkably, common themes persist that predict the evolution of species as readily as the orbits of planets or the collapse of stars into black holes. This book tells the history of spaces of expanding dimension and increasing abstraction and how they continue today to give new insight into the physics of complex systems. Galileo published the first modern law of motion, the Law of Fall, that was ideal and simple, laying the foundation upon which Newton built the first theory of dynamics. Early in the twentieth century, geometry became the cause of motion rather than the result when Einstein envisioned the fabric of space-time warped by mass and energy, forcing light rays to bend past the Sun. Possibly more radical was Feynman’s dilemma of quantum particles taking all paths at once—setting the stage for the modern fields of quantum field theory and quantum computing. Yet as concepts of motion have evolved, one thing has remained constant, the need to track ever more complex changes and to capture their essence, to find patterns in the chaos as we try to predict and control our world.

AbstractWe report on our project to study the activity in both the Sun and low mass stars. Utilising high cadence, Hα observations of a filament eruption made using the CRISP spectropolarimeter mounted on the Swedish Solar Telescope has allowed us to determine 3D velocity maps of the event. To gain insight into the physical mechanism which drives the event we have qualitatively compared our observation to a 3D MHD reconnection model. Solar-type and low mass stars can be highly active producing flares with energies exceeding erg. Using K2 and TESS data we find no correlation between the number of flares and the rotation phase which is surprising. Our solar flare model can be used to aid our understanding of the origin of flares in other stars. By scaling up our solar model to replicate observed stellar flare energies, we investigate the conditions needed for such high energy flares.

Mexico exerts a unique influence on Texas through immigration. As immigrants bring perspectives from their country of origin when they immigrate, studying attitudes toward capital punishment in Mexico may provide insight into ways Mexican immigrants could affect its future practice in Texas. Multilevel modeling is used to examine individual- and state-level predictors of death penalty support among a nationally representative sample of Mexicans. Results indicate age and Catholic affiliation are associated with death penalty support, although not in the expected directions, whereas states bordering the United States are less likely to support capital punishment, despite experiencing less overall peace and a higher average homicide rate. Findings suggest the need for researchers to use culture-specific factors to predict death penalty support.

Solar activity research provides insight into the Sun’s past, future (Science Daily, 2018). The solar activity includes observations of large numbers of intense sunspots, flares, and other phenomena; and demands a wide range of techniques and measurements on the observations. This research needs long term data collection before critical analyses can occur, to generate meaningful learning and knowledge. In this project, we will use solar imaging to make observations of solar activity, and take our baby steps to make contributions in citizen science. Observations will be made in 3 wavelengths to gain a more thorough analysis by looking at different perspectives of the Sun, namely H-Alpha, Calcium-K, and white light.

Qualitative research methods have long set an example of rich description, in which data and researchers’ hermeneutics work together to inform readers of findings in specific contexts. Among published works, insight into the analytical process is most often represented in the form of methodological propositions or research results. This paper presents a third type of qualitative report, one in which the researcher’s process of coding, finding themes, and arriving at findings is the focus. Grounded theory analysis methods were applied to the interpretation of a single interview. The resulting document provides a narrative of the process one researcher followed when attempting to apply recommended methodological procedures to a single interview, providing a peek inside the black box of analysis often left unopened in final reports.

Why do colors change? In outer space, the sky is black and the Sun is a white disc, visible only in the direct line of sight—there is nothing to scatter its light. Here on Earth, in normal daylight the molecules and dust in the atmosphere...

Radio astronomy has been expanding into outer space so fast in recent years that it is pleasant to find our own solar system at last receiving the attention it deserves. In this session we are concerned with everything within the system except the sun and our own planet. I start with a question, to which I shall return later: Where does the sun end? In another session you will hear of the experiments on the far-out parts of the solar corona; here we are concerned with interplanetary space as well as with the planets themselves, and what lies within this region may or may not be considered part of the solar corona.

Abstract Over recent decades, scholars have explored political parties’ adoption of digital technology. Tracing successive eras of change, scholarship has examined the degree to which digital disrupts or embeds traditional power structures—with many studies finding evidence of ‘controlled-interactivity’. In this article, we revisit debates around the adoption of digital tools from a bottom-up perspective. Moving beyond attempts to categorise elite strategies for digital adoption, we consider practices on the ground to document how, in practice, digital technology is being taken up and used. Using a case study of the UK Labour Party, we categorise a range of different practices, highlighting and theorising the presence of digital adherents, laggards, entrepreneurs, renegades and refuseniks. Discussing the drivers of these practices, we offer new insight into variations in digital adoption and consider the significance of these trends for our understanding of party organisation.

A key objective for the women, peace, and security agenda going forward is to disaggregate the experiences of women as a group, and to understand how gender functions in conflict contexts. This chapter focuses on the diverse roles of female combatants in rebel groups to gain insight into how power is distributed, not only between men and women, or combatants and civilians, but within groups. Rebel groups are characterized by military and political apparatuses that are built side by side and often entangled. Organizational power structures are often dominated by men, but not exclusively so. Using interviews and archival data from the Sierra Leone Civil War case study, this chapter delivers an analysis of women’s experiences in rebel movements. It explores the individual trajectories of mobilization and victimization in Sierra Leone. Next, it examines the unique experiences of female combatants, before situating them in the broader political context. Finally, the chapter considers cases of sexual violence, intimate partnerships, conflict among women, and the political entrepreneurship of elite women to understand female participation in rebellion in its entirety.
