Discrete Solitons and Breathers with Dilute Bose-Einstein Condensates
We study the dynamical phase diagram of a dilute Bose-Einstein condensate
(BEC) trapped in a periodic potential. The dynamics is governed by a discrete
non-linear Schr\"odinger equation: intrinsically localized excitations,
including discrete solitons and breathers, can be created even if the BEC's
interatomic potential is repulsive. Furthermore, we analyze the
Anderson-Kasevich experiment [Science 282, 1686 (1998)], pointing out that mean
field effects lead to a coherent destruction of the interwell Bloch
oscillations
A Modern Natural Theology?
The author examines two different traditions of nineteenth-century natural theology and their reappearance in a modern work. Michael Denton\'s Nature\'s Destiny is used as an
example of modern natural theology, showing how current writers attempt to resurrect the
classical arguments of William Paley and William Whewell. The stance taken here is that,
due to the heavily historical character of Foley\'s and Whewell\'s work, it is inappropriate to use their traditions uncritically as windows into religious understandings of science

Punishment and penal activity : the expansion of legal fines and fees in Texas from 1985 to 2015
Across the United States, legal fines and fees generate millions of dollars per year in revenue despite widening the net of criminalization and increasing penal severity for poorer individuals. Unlike in other penal policy domains, legal fines and fees represent an ambiguously defined form of punishment that has received bipartisan support. Understudied is how legal fines and fees have become an increasingly preferred policy choice among state-level political actors. In this study, I use archival data on legal statutes and legislative sessions in Texas – home to one of the largest prison and jail system in the U.S. – to investigate the development of legal fines and fees across a 30-year period. I use insights from socio-political and legal theories to offer a comprehensive analysis of the structure of legislative policy networks and the development of legal fines and fees legislation. I demonstrate that both liberal and conservative political actors facilitated the passage of legal debt legislation. Furthermore, I consider the role of legislative testimony to show the association between testimony and the rate of legislation on legal fines and fees. I discuss the implications of my findings for understanding how policy networks and legislative activity are related to criminal justice outcomes and are influenced by a variety of social actors. My study contributes to theoretical explanations on the roles of state actors in developing policies that become increasingly implicated in social inequalities.Sociolog
Ending Jim Crow Life Insurance Rates
his Article tells the story of the rise and fall of explicit race-based pricing practices as American life insurance companies responded to changes in the social, economic, and legal status of former slaves. The role of law in that story, from the Civil War to the beginning of this century, illustrates the complex interaction between civil rights reform and private commercial markets. Despite early laws prohibiting race-based life insurance rates, racial discrimination persisted in various forms for over a century due to the strength of the underlying racial ideologies, the rhetorical power of actuarial language, and the structure and regulation of insurance markets. Life insurance companies reinforced prevailing American assumptions about race by adopting explicit race-based pricing categories after Reconstruction, and later, by prospectively abandoning them beginning after World War II. Earlier this century, regulatory investigations and litigation under post-Civil War federal civil rights statutes brought relief to those harmed by the continuing effects of dual rate structures in race-segmented markets. Civil rights law thus served primarily as prologue, by provoking company adaptation, and as epilogue, by providing retrospective relief, to the central story of that transformation
