THE AMERICAN IMPRINT ON ALBERTA POLITICS
Characteristics assigned to America\u27s classical liberal ideology-rugged individualism, market capitalism, egalitarianism in the sense of equality of opportunity, and fierce hostility toward centralized federalism and socialismare particularly appropriate for fathoming Alberta\u27s political culture. In this article, I contend that Alberta\u27s early American settlers were pivotal in shaping Alberta\u27s political culture and that Albertans have demonstrated a particular affinity for American political ideas and movements. Alberta came to resemble the liberal society in Tocqueville\u27s Democracy in America: high status was accorded the selfmade man, laissez-faire defined the economic order, and a multiplicity of religious sects competed in the market for salvation.1 Secondary sources hint at this thesis in their reading of the papers of organizations such as the United Farmers of Alberta (UFA) and Alberta\u27s Social Credit Party.2 This article teases out its hypothesis from such secondary sources and covers new ground in linking the influence of Americans to Alberta\u27s exceptionalism in Canadian politics, the province where federal and provincial conservative parties have been strongest and where resistance to federal intrusions has been the most vigorous in English Canada. Alberta has been Canada\u27s maverick province, more receptive to neoliberalism (or what many term neoconservatism) than the Canadian norm

Quantization from Hamilton-Jacobi theory with a random constraint
We propose a method of quantization based on Hamilton-Jacobi theory in the
presence of a random constraint due to the fluctuations of a set of hidden
random variables. Given a Lagrangian, it reproduces the results of canonical
quantization yet with a unique ordering of operators if the Lagrange multiplier
that arises in the dynamical system with constraint can only take binary values
with equal probability.Comment: 6 pages, accepted for publication in Physica
Thermodynamic Fingerprints of Disorder in Flux Line Lattices and other Glassy Mesoscopic Systems
We examine probability distributions for thermodynamic quantities in
finite-sized random systems close to criticality. Guided by available exact
results, a general ansatz is proposed for replicated free energies, which leads
to scaling forms for cumulants of various macroscopic observables. For the
specific example of a planar flux line lattice in a two dimensional
superconducting film near H_c1, we provide detailed results for the statistics
of the magnetic flux density, susceptibility, heat capacity, and their
cross-correlations.Comment: 4 page
Quantization from an exponential distribution of infinitesimal action
A statistical model of quantization based on an exponential distribution of
infinitesimal action is proposed. Trajectory which does not extremize the
action along an infinitesimal short segment of path is allowed to occur with a
very small probability following an exponential law. Planck constant is argued
to give the average deviation from the infinitesimal stationary action.Comment: 15 pages, accepted for publication in Physica
Decoherence control in microwave cavities
We present a scheme able to protect the quantum states of a cavity mode
against the decohering effects of photon loss. The scheme preserves quantum
states with a definite parity, and improves previous proposals for decoherence
control in cavities. It is implemented by sending single atoms, one by one,
through the cavity. The atomic state gets first correlated to the photon number
parity. The wrong parity results in an atom in the upper state. The atom in
this state is then used to inject a photon in the mode via adiabatic transfer,
correcting the field parity. By solving numerically the exact master equation
of the system, we show that the protection of simple quantum states could be
experimentally demonstrated using presently available experimental apparatus.Comment: 13 pages, RevTeX, 8 figure
Einstein, incompleteness, and the epistemic view of quantum states
Does the quantum state represent reality or our knowledge of reality? In
making this distinction precise, we are led to a novel classification of hidden
variable models of quantum theory. Indeed, representatives of each class can be
found among existing constructions for two-dimensional Hilbert spaces. Our
approach also provides a fruitful new perspective on arguments for the
nonlocality and incompleteness of quantum theory. Specifically, we show that
for models wherein the quantum state has the status of something real, the
failure of locality can be established through an argument considerably more
straightforward than Bell's theorem. The historical significance of this result
becomes evident when one recognizes that the same reasoning is present in
Einstein's preferred argument for incompleteness, which dates back to 1935.
This fact suggests that Einstein was seeking not just any completion of quantum
theory, but one wherein quantum states are solely representative of our
knowledge. Our hypothesis is supported by an analysis of Einstein's attempts to
clarify his views on quantum theory and the circumstance of his otherwise
puzzling abandonment of an even simpler argument for incompleteness from 1927.Comment: 18 pages, 8 figures, 1 recipe for cupcakes; comments welcom

Matrix stiffening sensitizes epithelial cells to EGF and enables the loss of contact inhibition of proliferation
Anchorage to a compliant extracellular matrix (ECM) and contact with neighboring cells impose important constraints on the proliferation of epithelial cells. How anchorage and contact dependence are inter-related and how cells weigh these adhesive cues alongside soluble growth factors to make a net cell cycle decision remain unclear. Here, we show that a moderate 4.5-fold stiffening of the matrix reduces the threshold amount of epidermal growth factor (EGF) needed to over-ride contact inhibition by over 100-fold. At EGF doses in the range of the dissociation constant (Kd) for ligand binding, epithelial cells on soft matrices are contact inhibited with DNA synthesis restricted to the periphery of cell clusters. By contrast, on stiff substrates, even EGF doses at sub-Kd levels over-ride contact inhibition, leading to proliferation throughout the cluster. Thus, matrix stiffening significantly sensitizes cells to EGF, enabling contact-independent spatially uniform proliferation. Contact inhibition on soft substrates requires E-cadherin, and the loss of contact inhibition upon matrix stiffening is accompanied by the disruption of cell–cell contacts, changes in the localization of the EGF receptor and ZO-1, and selective attenuation of ERK, but not Akt, signaling. We propose a quantitative framework for the epigenetic priming (via ECM stiffening) of a classical oncogenic pathway (EGF) with implications for the regulation of tissue growth during morphogenesis and cancer progression
Alliance or acquisition? A mechanisms‐based, policy‐capturing analysis
Research summary: While alliance researchers view prior partner‐specific alliance experience as influencing firms' subsequent alliance or acquisition decisions, empirical evidence on the alliance versus acquisition decision is surprisingly mixed. We offer a reconciliation by proposing and testing an analytical framework that recognizes prior partner‐specific experiences as heterogeneous along three fundamental dimensions: partner‐specific trust, routines, and value certainty. This allows us to use a policy‐capturing methodology to rigorously operationalize and test our mechanism‐level predictions. We find that all three mechanisms can increase the likelihood of a subsequent alliance or acquisition, and in terms of the comparative choice between alliances versus acquisitions, partner‐specific trust pulls towards alliances, and value certainty pulls towards acquisitions. We conclude with a discussion of the theoretical and empirical implications of our approach and method.
Managerial summary: This study focuses on an important corporate decision: When a firm has had an alliance with another firm, how would that experience affect the likelihood of a future alliance or acquisition with that same firm? We first suggest that it will depend on three factors: the level of trust that existed in that prior alliance, the extent to which specific work routines were developed, and the degree to which the firm was able to confidently assess the value of the partner firm's resources. We then find that trust is a particularly strong predictor of future alliances, while confidence regarding value more strongly predicts future acquisitions. In this way, we demonstrate more precisely how past corporate choices can affect (consciously or unconsciously) future ones
