description: The notion of a complete Boolean algebra, although completely legitimate in constructive mathematics, fails to capture some natural structures such as the lattice of subsets of a given set. Sambin's notion of an overlap algebra, although classically equivalent to that of a complete Boolean algebra, has powersets and other natural structures as instances. In this paper we study the category of overlap algebras as an extension of the category of sets and relations, and we establish some basic facts about mono-epi-isomorphisms and (co)limits; here a morphism is a symmetrizable function (with classical logic this is just a function which preserves joins). Then we specialize to the case of morphisms which preserve also finite meets: classically, this is the usual category of complete Boolean algebras. Finally, we connect overlap algebras with locales, and their morphisms with open maps between locales, thus obtaining constructive versions of some results about Boolean locales.

description: The announcement of the discovery of a Higgs boson-like particle at CERN will be remembered as one of the milestones of the scientific endeavor of the 21st century. In this paper we present a study of information spreading processes on Twitter before, during and after the announcement of the discovery of a new particle with the features of the elusive Higgs boson on 4th July 2012. We report evidence for non-trivial spatio-temporal patterns in user activities at individual and global level, such as tweeting, re-tweeting and replying to existing tweets. We provide a possible explanation for the observed time-varying dynamics of user activities during the spreading of this scientific "rumor". We model the information spreading in the corresponding network of individuals who posted a tweet related to the Higgs boson discovery. Finally, we show that we are able to reproduce the global behavior of about 500,000 individuals with remarkable accuracy.

description: We study the Sierpinski object $Σ$ in the realizability topos based on Scott's graph model of the $λ$-calculus. Our starting observation is that the object of realizers in this topos is the exponential $Σ^N$, where $N$ is the natural numbers object. We define order-discrete objects by orthogonality to $Σ$. We show that the order-discrete objects form a reflective subcategory of the topos, and that many fundamental objects in higher-type arithmetic are order-discrete. Building on work by Lietz, we give some new results regarding the internal logic of the topos. Then we consider $Σ$ as a dominance; we explicitly construct the lift functor and characterize $Σ$-subobjects. Contrary to our expectations the dominance $Σ$ is not closed under unions. In the last section we build a model for homotopy theory, where the order-discrete objects are exactly those objects which only have constant paths.

description: We introduce MSO graph storage types, and call a storage type MSO-expressible if it is isomorphic to some MSO graph storage type. An MSO graph storage type has MSO-definable sets of graphs as storage configurations and as storage transformations. We consider sequential automata with MSO graph storage and associate with each such automaton a string language (in the usual way) and a graph language; a graph is accepted by the automaton if it represents a correct sequence of storage configurations for a given input string. For each MSO graph storage type, we define an MSO logic which is a subset of the usual MSO logic on graphs. We prove a Büchi-Elgot-Trakhtenbrot theorem, both for the string case and the graph case. Moreover, we prove that (i) each MSO graph transduction can be used as storage transformation in an MSO graph storage type, (ii) every automatic storage type is MSO-expressible, and (iii) the pushdown operator on storage types preserves the property of MSO-expressibility. Thus, the iterated pushdown storage types are MSO-expressible.
Proofs of the Kochen-Specker theorem based on the N-qubit Pauli group

description: We present a number of observables-based proofs of the Kochen-Specker (KS) theorem based on the N-qubit Pauli group for N >= 4, thus adding to the proofs that have been presented earlier for the two- and three-qubit groups. These proofs have the attractive feature that they can be presented in the form of diagrams from which they are obvious by inspection. They are also irreducible in the sense that they cannot be reduced to smaller proofs by ignoring some subset of qubits and/or observables in them. A simple algorithm is given for transforming any observables-based KS proof into a large number of projectors-based KS proofs; if the observables-based proof has O observables, with each observable occurring in exactly two commuting sets and any two commuting sets having at most one observable in common, the number of associated projectors-based parity proofs is 2^O. We introduce symbols for the observables- and projectors-based KS proofs that capture their important features and also convey a feeling for the enormous variety of both these types of proofs within the N-qubit Pauli group. We discuss an infinite family of observables-based proofs, whose members apply to all numbers of qubits from two up, and show how it can be used to generate projectors-based KS proofs involving only nine bases (or experimental contexts) in any dimension of the form 2^N for N >= 2. Some implications of our results are discussed.

description: This capstone project addresses the design and implementation of a device that measures arm position and speed. The device is intended for use in conducting further research on the motion of limbs affected by cerebral palsy, and in the prototypic development of a device that could help control such motion, thereby allowing a user to accomplish daily tasks. This project includes the design of an appropriate experiment and testing apparatus to explore possible solution prototypes, along with suggested methods to perform analysis of the experiment results. This is considered to be the fundamental research necessary to better understand the scope and requirements that a prototype design would need. The results of this experimental research will provide recommendations for moving forward in the development of an Arm Stabilizer device.

description: We study multiplayer quantitative reachability games played on a finite directed graph, where the objective of each player is to reach his target set of vertices as quickly as possible. Instead of the well-known notion of Nash equilibrium (NE), we focus on the notion of subgame perfect equilibrium (SPE), a refinement of NE well-suited in the framework of games played on graphs. It is known that there always exists an SPE in quantitative reachability games and that the constrained existence problem is decidable. We here prove that this problem is PSPACE-complete. To obtain this result, we propose a new algorithm that iteratively builds a set of constraints characterizing the set of SPE outcomes in quantitative reachability games. This set of constraints is obtained by iterating an operator that reinforces the constraints up to obtaining a fixpoint. With this fixpoint, the set of SPE outcomes can be represented by a finite graph of size at most exponential. A careful inspection of the computation allows us to establish PSPACE membership.

description: After fixing a canonical ordering (or labeling) of the elements of a finite poset, one can associate each linear extension of the poset with a permutation. Some recent papers consider specific families of posets and ask how many linear extensions give rise to permutations that avoid certain patterns. We build off of two of these papers. We first consider pattern avoidance in $k$-ary heaps, where we obtain a general result that proves a conjecture of Levin, Pudwell, Riehl, and Sandberg in a special case. We then prove some conjectures that Anderson, Egge, Riehl, Ryan, Steinke, and Vaughan made about pattern-avoiding linear extensions of rectangular posets.

description: Let $k$ be an algebraically closed field of characteristic $0$ and $A$ a graded $k$-algebra finitely generated in degree $1$. In this paper, for $3$-dimensional quadratic AS-regular algebras except for Type EC, we give a complete list of twisted superpotentials and a complete list of superpotentials such that derivation-quotient algebras are $3$-dimensional quadratic Calabi-Yau AS-regular algebras. For an algebra $A$ of Type EC, we give a criterion when $A$ is AS-regular. As an application, for an algebra $A$ of any type, we show that there exists a Calabi-Yau AS-regular algebra $S$ such that $A$ and $S$ are graded Morita equivalent. This result tells us that, for a $3$-dimensional quadratic AS-regular algebra $A$, to study the noncommutative projective scheme for $A$ defined by Artin-Zhang is reduced to study the noncommutative projective scheme for $S$ for the Calabi-Yau AS-regular algebra $S$.

description: If the massive neutrinos are identified to be the Majorana particles via a convincing measurement of the neutrinoless double beta (0νββ) decay, how to determine the Majorana CP-violating phases in the 3 x 3 lepton flavor mixing matrix U will become a desirable experimental question. The answer to this question is to explore all the possible lepton-number-violating (LNV) processes in which the Majorana phases really matter. In this paper we carry out a systematic study of CP violation in neutrino-antineutrino oscillations, whose CP-conserving parts involve six independent 0νββ-like mass terms _{αβ} and CP-violating parts are associated with nine independent Jarlskog-like parameters V^{ij}_{αβ} (for α, β= e, μ, τand i, j = 1, 2,3). With the help of current neutrino oscillation data, we analyze the sensitivities of |_{αβ}| and V^{ij}_{αβ} to the three CP-violating phases of U, and illustrate the salient features of six independent CP-violating asymmetries between ν_α\to \barν_βand \barν_α\to ν_βoscillations. As a by-product, the effects of the CP-violating phases on the LNV decays of doubly- and singly-charged Higgs bosons are reexamined by taking account of the unsuppressed value of θ_{13}. Such CP-conserving LNV processes can be complementary to the possible measurements of neutrino-antineutrino oscillations in the distant future.

description: [Abridged] NGC 5238 and NGC 4756 are the brightest unperturbed elliptical galaxies in their respective loose groups. In the present study we aim at characterizing the properties of the hot gas in the halos of the brightest members and in the environment. In NGC 4756 we are also interested in the properties of a substructure identified to the SW and the region connecting the two structures, to search for a physical connection between the two. However, we have to take into account the fact that the group is projected against the bright, X-ray emitting cluster A1361, which heavily contaminates and confuses the emission from the foreground structure. We present a careful analysis of XMM-Newton data of the groups to separate different components. We also present a re-evaluation of the dynamical properties of the systems and . SPH simulations to interpret the results. We find that the X-ray source associated with NGC 4756 indeed sits on top of extended emission from the background cluster A1361, but can be relatively well distinguished from it as a significant excess over it out to r\sim150"\ (~40 kpc). NGC 4756 has an X-ray luminosity of ~10^41 erg/s due to hot gas, with an average temperature of kT\sim0.7 keV. We measure a faint diffuse emission also in the region of the subclump to the SW, but more interestingly, we detect gas between the two structures, indicating a possible physical connection. The X-ray emission from NGC 5328 is clearly peaked on the galaxy, also at 10^41 erg/s, and extends to r\sim110 kpc. Simulations provide an excellent reproduction of the SED and the global properties of both galaxies, which are caught at two different epochs of the same evolutionary process, with NGC 5328 ~2.5 Gyr younger than NGC 4756.

description: Within a geometrical context, we derive an explicit formula for the computation of the symmetric logarithmic derivative for arbitrarily mixed quantum systems, provided that the structure constants of the associated unitary Lie algebra are known. To give examples of this procedure, we first recover the known formulae for two-level mixed and three-level pure state systems and then apply it to the novel case of U(3), that is for arbitrarily mixed three-level systems (q-trits). Exploiting the latter result, we finally calculate an expression for the Fisher tensor for a q-trit considering also all possible degenerate subcases.

description: A system of a two-level atom of an impurity (qubit) inserted into a periodic chain coupled to the continuum is studied with the use of the effective non-Hermitian Hamiltonian. Exact solutions are derived for the quasistationary eigenstates, their complex energies, and transport properties. Due to the presence of the qubit, two long-lived states corresponding to the ground and excited states of the qubit emerge outside the Bloch energy band. These states remain essentially localized at the qubit even in the limit of sufficiently strong coupling between the chain and the environment when the super-radiant states are formed. The transmission through the chain is studied as a function of the continuum coupling strength and the chain-qubit coupling; the perfect resonance transmission takes place through isolated resonances at weak and strong continuum coupling, while the transmission is lowered in the intermediate regime.
description: In this version we added the case of large N and the case when the excitation energy of bare qubit is below the band boundary of the bare chain. The captions to some figures are modified. Some new references are added

description: In reactive synthesis, the goal is to automatically generate an implementation from a specification of the reactive and non-terminating input/output behaviours of a system. Specifications are usually modelled as logical formulae or automata over infinite sequences of signals ($ω$-words), while implementations are represented as transducers. In the classical setting, the set of signals is assumed to be finite. In this paper, we consider data $ω$-words instead, i.e., words over an infinite alphabet. In this context, we study specifications and implementations respectively given as automata and transducers extended with a finite set of registers. We consider different instances, depending on whether the specification is nondeterministic, universal or deterministic, and depending on whether the number of registers of the implementation is given or not. In the unbounded setting, we show undecidability for both universal and nondeterministic specifications, while decidability is recovered in the deterministic case. In the bounded setting, undecidability still holds for nondeterministic specifications, but can be recovered by disallowing tests over input data. The generic technique we use to show the latter result allows us to reprove some known result, namely decidability of bounded synthesis for universal specifications.
title: Rise of the KKK: Political Rhetoric of the 1920s Ku Klux Klan in the West
Creators: name: Larsen, Justine S. I.
Publisher: name: Utah State University
Year: 2018

description: Recent works illustrate the significance of understanding the nuances of the Ku Klux Klan of the 1920s in the context of demographic and geographic differences. Using archival documents, newspaper records, and published works, this analysis dissects the differences in the Klan's ideology manifested within Utah, Idaho, and Oregon. Categorizing the Klan as a violent, extremist group with great political influence does not accurately describe any one of the Klans in these three states. While the Klan in Oregon and Idaho demonstrated varying levels of political power throughout their respective states, Utah's unique mostly homogenous religious, and therefore political, environment rendered the state relatively immune to Klan political influence. Utah, however, was no more immune to anti-Catholic sentiments than the other two, revealing an underlying theme throughout the three states. Utah's Mormon dominated culture is the reason behind its differences in Klan activity; Idaho and Oregon differ primarily in the strength with which their respective Klan's demonstrated. While similar in ideological emphasis and political infiltration, Oregon's Klan was much larger and more powerful politically than Idaho's. Understanding each state's Klan individually is foundational in adequately comparing the three states' experience in Klanism. It is equally important to note that anti-Catholicism as a part of the national Klan's platform presented itself in each of the three states. The differences in which these discriminatory sentiments surfaced in each of the states, burning crosses and parading in Utah and Idaho and codifying anti-Catholicism through exclusionary school legislation in Oregon, illustrates the understanding lost when making blanket statements about the 1920s Klan. Providing a state-wide comparison of the Klan in three western states reveals the differing significant characteristics evident in each state. The second wave Klan, while consistent in its anti-Catholic sentiments across Utah, Idaho, and Oregon, is incompletely characterized as a stratified, cohesive organization. The differences between the states reflect the importance of analyzing the Klan on a local level in order to understand the nuances of the Klan by geographic location, revealing a more rich and detailed understanding of the mechanisms and motivations of the Klan.
title: Algorithmic Trading for Cryptocurrencies

description: This project takes several common strategies for algorithmic stock trading and tests them on the cryptocurrency market. The three strategies used are moving average crossover, mean reversion, and pairs trading. Data was collected every five minutes for the top one hundred cryptocurrencies between October 5, 2017, and January 24, 2018. Due to the high volatility of the market, the data includes various market situations. Three noted situations are a rising market, falling market, and relatively stable market. The three strategies were modified to optimally follow each market situation. Modifications include adjusting parameters used in each strategy as well as mixing several strategies or dynamically changing between strategies. In each strategy and with each cryptocurrency, the benchmark against which the algorithm is tested is the market's performance, or what an investor would have after buying and holding. Returns are compared with the buying and holding strategy, and different scenarios are analyzed to determine the risk associated with buying and holding compared with an algorithmic strategy. Results will be taken with the market's actual trends and also with some alternate possible trends to test all market scenarios. A web interface will accompany the presentation, allowing users to test the strategies by entering their own parameters and instantly see the results.

description: We suggest that stable states of positronium might exist in the jets of active galactic nuclei (AGN). Electrons and positrons are created near the accretion disks of supermassive black holes at the centers of AGN and are accelerated along magnetic field lines while within the {\sl Alfvén radius}. The conditions in this region are ideal for the creation of bound states of positronium which are stable against annihilation. Traveling at relativistic speeds along the jet, the helical magnetic field enables the atoms to survive for great distances.
title: Managing Dietary Protein in Cattle as a Means of Reducing Ammonia Emissions to Improve Air Quality
Creators: name: Houston, Ashley
Publisher: name: Utah State University
Year: 2018

description: Particulate matter pollution has become a subject of great concern across the globe. Emissions data has revealed that the agricultural sector is making large contributions to particulate matter through ammonia emissions. Beef and dairy cattle are responsible for producing nearly 50% of annual ammonia emissions in the United States. These animals are often fed amounts of dietary protein that exceed recommendations, resulting in increased excretion of urea and ammonia. These compounds combine with nitrogen oxides in the atmosphere to form PM2.5: particulate matter measuring less than 2.5 microns in diameter. Research has shown that through proper dietary management of protein, ammonia emissions in the agricultural sector can be reduced, leading to a healthier environment. Unfortunately, dietary protein is often overfed to cattle to promote increased production. As such, this research aims to better inform producers of the environmental and health risks that arise when dietary protein is not properly balanced, and to encourage evaluation of current diets in order to assess feed efficiency and identify instances of overfeeding.

description: In two-player games on graphs, the players move a token through a graph to produce an infinite path, which determines the winner of the game. Such games are central in formal methods since they model the interaction between a non-terminating system and its environment. In bidding games the players bid for the right to move the token: in each round, the players simultaneously submit bids, and the higher bidder moves the token and pays the other player. Bidding games are known to have a clean and elegant mathematical structure that relies on the ability of the players to submit arbitrarily small bids. Many applications, however, require a fixed granularity for the bids, which can represent, for example, the monetary value expressed in cents. We study, for the first time, the combination of discrete-bidding and infinite-duration games. Our most important result proves that these games form a large determined subclass of concurrent games, where determinacy is the strong property that there always exists exactly one player who can guarantee winning the game. In particular, we show that, in contrast to non-discrete bidding games, the mechanism with which tied bids are resolved plays an important role in discrete-bidding games. We study several natural tie-breaking mechanisms and show that, while some do not admit determinacy, most natural mechanisms imply determinacy for every pair of initial budgets.

description: The many benefits of utilizing teff (Eragrostis tef) as small grain is well documented in journal publications. Over time the domestication of this species has become essential to the diets of the local population and the livestock living in the African highlands. Current research points to a high diversity of trait characteristics found in many teff populations and the potential utilization of these traits to increase desirable characteristics in both grain and forage varieties. With the overarching goal of adding to what is already known about teff, this study evaluates the different traits that are of interest to local and international markets, compares improved varieties to the current US based germplasm collection in a field study, and evaluates differences in reported nutrient classes using a meta-analysis. The results of this study show that increased popularity of teff on the global market, may impact food security if resilient varieties and sustainable practices are not utilized. The high diversity of traits found in the germplasm collection have the potential to increase desirable forage traits in future breeding lines. The development of reduced logging varieties may increase the grain harvest for small hold farmers. The meta-analysis shows that although white seed color might be preferred, the nutrients found in the darker colored seed are more diverse in profile.

description: Suppose that in a given planar circular region, there are some smart mobile evaders and we would like to find them using sweeping agents. We assume that the sweeping agents are in a line formation whose total length is 2r. We propose procedures for designing a sweeping process that ensures the successful completion of the task, thereby deriving conditions on the sweeping velocity of the linear formation and its path. Successful completion of the task means that evaders with a given limit on their velocity cannot escape the sweeping agents. A simpler task for the sweeping formation is the confinement of the evaders to their initial domain. The feasibility of completing these tasks depends on geometric and dynamic constraints that impose a lower bound on the velocity that the sweeper line formation must have. This critical velocity is derived to ensure the satisfaction of the confinement task. Increasing the velocity above the lower bound enables the agents to complete the search task as well. We present results on the total search time as a function of the sweeping velocity of the formation given the initial conditions on the size of the search region and the maximal velocity of the evaders.
title: Don't Panic: A Music Therapy Student's Journey
Creators: name: Anjewierden, Kira Lynn
Publisher: name: Utah State University

description: Many college students change majors at some point in their undergraduate study. Studies have found that students who change their major late in their education are more likely to graduate from the institution at which they started than those who switch before their 5th semester. At its conception, the purpose of Don't Panic: A Music Student 's Journey was to serve as an informative source for those interested in the Music Therapy Program at Utah State University, reflecting on both the requirements and the process through the experience of one student. In the time since, the author changed majors, and additional intentions were added - to provide an experiential model that could support students who may find themselves in a similar position of change and self-discovery. In order to achieve this goal, the author developed a program of music to best embody her emotions through the undergraduate experience. A script was then written, detailing the events around each song, and a PowerPoint presentation was created to support the music, and house narrations of the script. The presentation took place on April 3rd, 2018.

description: Momentum imaging measurements from two experiments are presented and interpreted with the aid of new ab initio theoretical calculations to describe the dissociative electron attachment (DEA) dynamics. We address the problem of how the 4 eV ^2Π_u shape resonance in CO_2 proceeds to dissociate to CO(^1Σ^+) + O^-(^2P) by DEA.
title: Much Ado About Acting
Creators: name: Harlan, Claire Louise
Publisher: name: Utah State University

description: To be an actor, one must have an understanding not only of theatrical craft, but also of the world that surrounds and informs theatre. During my undergraduate training, I have pursued a variety of diverse academic skills and extracurricular talents, all of which I have been able to relate back to my primary field--the performing arts. I am particularly interested in the intersection between studies in Theatre Arts and studies in English, as those are my two majors. Literary analysis, research, and reflective writing can unlock an actor's interpretation of a role. The actor who combines these two fields is the actor who is able to touch the most lives through performance, which is ultimately theatre's noblest goal.
The plays of William Shakespeare serve as a bridge between Theatre and English departments. Not only are they immensely popular with audiences of all ages, they also offer unique challenges to actors and are goldmines for literary research and analysis. One of Shakespeare's most popular comedies is Much Ado About Nothing, an early example of the romantic comedy or "rom-com" genre. That is not to say that the play does not present any challenges; in particular, the actor portraying Beatrice must be both sharp-tongued and vulnerable, quick-witted and unsuspecting, independent and insecure. In order to inhabit all her contradictions, the actor must use every available tool to unpack the character and give a successful performance. The scholar must also bridge a four hundred year gap to correctly interpret the play; the English language has evolved, social and political climates have shifted, and the world itself has shrunk.
The goal of this project was to explore the ways I could bridge my education and demonstrate that this can result in a rich and well-informed theatrical representation of one of Shakespeare's most beloved heroines. I aim to give the reader a comprehensive understanding of an actor's process from the moment they are cast to the final fall of the curtain on closing night. On a more personal level, I sought to understand how I can use all the tools at my disposal-both literary and theatrical-to deepen my understanding and execution of a role. From research to preparatory work to rehearsal to performance, how can one combine every tool and resource into a cohesive, authentic experience on stage? I found that every single step in the actor's process is crucial, even though it can feel, at times, like the amount of work that goes into each role is excessive. Even though every single fact or tool may not be used specifically, having that arsenal to draw upon during performance is invaluable. Though it may seem counterintuitive, it allows the actor to relax into the role and be truly alive and present in the moment as their character in the world of the play on stage.
title: Designing a Synthetic Spider Silk-Based Coating for Urinary Catheters to Reduce the Risk of CAUTIs
Creators: name: Cook, Alexander
Publisher: name: Utah State University
Year: 2018

description: Urinary  and  Intravenous  (IV) catheters  are two of the most  commonly  used medical  devices  for administering  vital  drugs  and  obtaining  diagnostic  samples  from patients.  Unfortunately, hospital acquired  infections  (HAIs)  occur  at alarming  rates due to catheter  usage.  The  aim of this  project was to design  a urinary  catheter  that  would  decrease  the occurrence  of these  infections  with  a catheter  coating  that  utilizes  the antimicrobial  properties  of synthetic  spider  silk  in combination with the antiseptic  chlorhexidine.  This  synthetic  spider  silk catheter  will  introduce  a novel approach  to catheterization  in the medical  industry.

description: We have investigated the influence of Fe-excess on the electrical transport and magnetism of Fe1+yTe0.5Se0.5 (y=0.04 and 0.09) single crystals. Both compositions exhibit resistively determined superconducting transitions (Tc) with an onset temperature of about 15 K. From the width of the superconducting transition and the magnitude of the lower critical field Hc1, it is inferred that excess of Fe suppresses superconductivity. The linear and non-linear responses of the ac-susceptibility show that the superconducting state for these compositions is inhomogeneous. A possible origin of this phase separation is a magnetic coupling between Fe-excess occupying interstitial sites in the chalcogen planes and those in the Fe-square lattice. The temperature derivative of the resistivity drho/dT in the temperature range Tc < T < Ta with Ta being the temperature of a magnetic anomaly, changes from positive to negative with increasing Fe. A log 1/T divergence of the resistivity above Tc in the sample with higher amount of Fe suggests a disorder driven electronic localization.

The role of pawnshops in risk coping in early twentieth-century Japan
Creators: name: Inoue, Tatsuki
Publisher: name: arXiv
Year: 2019
Subjects: subject: General Economics (econ.GN)
subject: FOS: Economics and business

description: This study examines the role of pawnshops as a risk-coping device in prewar Japan. Using data on pawnshop loans for more than 250 municipalities and exploiting the 1918-1920 influenza pandemic as a natural experiment, we find that the adverse health shock increased the total amount of loans from pawnshops. This is because those who regularly relied on pawnshops borrowed more money from them than usual to cope with the adverse health shock, and not because the number of people who used pawnshops increased.

Marriage patterns in two Wiltshire parishes 1754-1914: geographical mobility, consanguinity and illegitimacy
Creators: name: Day, Cathy
Publisher: name: The Australian National University
Year: 2010
Subjects: consanguinity, illegitimacy, geographical mobility, Wiltshire, England, cousin marriage, class differences, religion, occupation

description: The aim of this project was to determine the birthplaces of spouses married in two parishes in England, how many married their relatives and how illegitimacy affected marital outcomes for all concerned. It considered the effect of religion and social class on the marital aspects of geographic mobility, consanguinity and illegitimacy. This project used a wide array of primary documentary sources that have recently become widely available to construct a database of over 22,000 individuals who lived in southwest Wiltshire in the 18th, 19th and 20th centuries. The author arranged the individuals in family groups and traced pedigrees for several generations. Information was included on religious affiliation, occupation and other variables, enabling the researcher to consider aspects of marital choices. It quantified separately the level of geographical mobility, consanguinity and illegitimacy, and then was able to consider the linkages between these aspects of marriage patterns. Geographical mobility calculated from birthplace was higher than estimates derived from residence prior to marriage. Catholics were found to be more inbred than Anglicans, despite having a lower level of 1st cousin marriage. Social class influenced consanguinity, as did illegitimate reproductive experience and geographical mobility. Mothers of illegitimate children were less mobile than other women, and more likely to marry their cousins. Family experience, particularly that of siblings, influenced illegitimacy and consanguinity rates. The interactions between geographical mobility, consanguinity and illegitimacy were complex and acted differently depending on social class. Members of higher social classes such as farmers had greater geographical mobility and higher levels of consanguinity, whereas amongst labourers, consanguineous marriage was associated with lower levels of geographical mobility. There was an association between being the mother of an illegitimate child and consanguineous marriage, but only amongst the labouring class.
