Oklahoman by blood: indigenous land tenure from Indian Territory to McGirt
After the McGirt v. Oklahoma decision in 2020, Oklahoma’s statehood became the subject of intense legal scrutiny regarding the supposed “disestablishment” of American Indian reservations. The State’s position follows a playbook all too familiar to citizens of Indian Country, resurfacing antiquated beliefs about what it means to be a tribal citizen and misrepresenting the historical forces that animate Oklahoma’s statehood movements. Writing with historians, Indigenous people, and interdisciplinary scholarship, this thesis will incorporate the analytical tools of Critical Indigenous Studies alongside archival and empirical methodologies. This thesis contextualizes Oklahoma’s tribal-state governance dynamic as a contest for land, resources, and life made possible by the logic of settler colonialism and white nationalism instrumental in both contemporary and historic struggles for American Indian legal and political recognition. To do this, I look at the contested history of Indigenous land tenure in Oklahoma beginning with Charles Page and the establishment of Sand Springs in chapter two, followed by the enmeshment of blood politics and internalized colonialism in chapter three, and ending chapter four with an analysis of three distinct statehood movements preceding Oklahoma’s entrance to the United States
Newspaper advertising, Retail Pricing Practices, and Gross Retail Margins for Turkeys in Selected Utah and Other U. S. Markets for Various Years and Seasons
Newspaper advertising and retail pricing practices for turkeys were ascertained and gross retail margins established for three Utah markets, 1955 to 1966, and for 12 other selected U. S. markets, 1965 and 1966. Turkey was extensively used as an advertised special item, particularly in holiday seasons. Food retailing organizations advertised turkey at low prices and margins at Thanksgiving and Christmas when consumer demand for turkey is traditionally strong. Prior to these holidays, food retailing organizations in a market simultaneously advertised turkey at identical prices and with little product differentiation thus limiting the effectiveness of turkey as an advertised item to gain competitive advantage for a food retailer
LaserTank is NP-complete
We show that the classical game LaserTank is -complete, even
when the tank movement is restricted to a single column and the only blocks
appearing on the board are mirrors and solid blocks. We show this by reducing
-SAT instances to LaserTank puzzles.Comment: 5 page
Is DEET safe for children?
Reported evidence suggests that DEET use is safe for children older than 2 months, with only very rare incidence of major adverse effects (strength of recommendation [SOR]: C). Typically, a topical concentration between 10% and 30% should be used (SOR: C). Increasing DEET concentration does not improve protection, but does increase the duration of action (SOR: A)
Finding community structure in very large networks
The discovery and analysis of community structure in networks is a topic of
considerable recent interest within the physics community, but most methods
proposed so far are unsuitable for very large networks because of their
computational cost. Here we present a hierarchical agglomeration algorithm for
detecting community structure which is faster than many competing algorithms:
its running time on a network with n vertices and m edges is O(m d log n) where
d is the depth of the dendrogram describing the community structure. Many
real-world networks are sparse and hierarchical, with m ~ n and d ~ log n, in
which case our algorithm runs in essentially linear time, O(n log^2 n). As an
example of the application of this algorithm we use it to analyze a network of
items for sale on the web-site of a large online retailer, items in the network
being linked if they are frequently purchased by the same buyer. The network
has more than 400,000 vertices and 2 million edges. We show that our algorithm
can extract meaningful communities from this network, revealing large-scale
patterns present in the purchasing habits of customers
Do Pine Trees in Aspen Stands Increase Bird Diversity
In the Black Hills of South Dakota, quaking aspen (Populus tremuloides) is being replaced by conifers through fire suppression and successional processes. Al- though the Black Hills National forest is removing conifers (primarily ponderosa pine [Pinus ponderosa])toincreasetheaspencommunitiesinsomemixedstands,ForestPlan guidelines allow four conifers per hectare to remain to increase diversity in the remaining aspen stand. We compared bird species richness in pure ponderosa pine, mixed stands dominated by ponderosa pine with quaking aspen, mixed stands dominated by aspen
with ponderosa pine, and pure aspen stands. Stands dominated by ponderosa pine had lower (
Coexistence of opposite opinions in a network with communities
The Majority Rule is applied to a topology that consists of two coupled
random networks, thereby mimicking the modular structure observed in social
networks. We calculate analytically the asymptotic behaviour of the model and
derive a phase diagram that depends on the frequency of random opinion flips
and on the inter-connectivity between the two communities. It is shown that
three regimes may take place: a disordered regime, where no collective
phenomena takes place; a symmetric regime, where the nodes in both communities
reach the same average opinion; an asymmetric regime, where the nodes in each
community reach an opposite average opinion. The transition from the asymmetric
regime to the symmetric regime is shown to be discontinuous.Comment: 14 pages, 4 figure
Looking our limitations in the eye: A call for more thorough and honest reporting of study limitations
The replication crisis and subsequent credibility revolution in psychology have highlighted many suboptimal research practices such as p‐hacking, overgeneralizing, and a lack of transparency. These practices may have been employed reflexively but upon reflection, they are hard to defend. We suggest that current practices for reporting and discussing study limitations are another example of an area where there is much room for improvement. In this article, we call for more rigorous reporting of study limitations in social and personality psychology articles, and we offer advice for how to do this. We recommend that authors consider what the best argument is against their conclusions (which we call the “steel‐person principle”). We consider limitations as threats to construct, internal, external, and statistical conclusion validity (Shadish et al., 2002), and offer some examples for better practice reporting of common study limitations. Our advice has its own limitations — both our representation of current practices and our recommendations are largely based on our own metaresearch and opinions. Nevertheless, we hope that we can prompt researchers to write more deeply and clearly about the limitations of their research, and to hold each other to higher standards when reviewing each other's work
Finding and evaluating community structure in networks
We propose and study a set of algorithms for discovering community structure
in networks -- natural divisions of network nodes into densely connected
subgroups. Our algorithms all share two definitive features: first, they
involve iterative removal of edges from the network to split it into
communities, the edges removed being identified using one of a number of
possible "betweenness" measures, and second, these measures are, crucially,
recalculated after each removal. We also propose a measure for the strength of
the community structure found by our algorithms, which gives us an objective
metric for choosing the number of communities into which a network should be
divided. We demonstrate that our algorithms are highly effective at discovering
community structure in both computer-generated and real-world network data, and
show how they can be used to shed light on the sometimes dauntingly complex
structure of networked systems.Comment: 16 pages, 13 figure
