description: We present a fundamental plane (FP) analysis of 141 early-type galaxies in the Shapley supercluster at z=0.049 based on spectroscopy from the AAOmega spectrograph at the AAT and photometry from the WFI on the ESO/MPI 2.2m telescope. The key feature of the survey is its coverage of low-mass galaxies down to sigma_0~50km/s. We obtain a best-fitting FP relation log r_e=1.06 log sigma_0 - 0.82 log < I >_e + cst in the R band. The shallow exponent of sigma_0 is a result of the extension of our sample to low velocity dispersions. We investigate the origin of the intrinsic FP scatter, using estimates of age, metallicity and alpha/Fe. We find that the FP residuals anti-correlate (>3sigma) with the mean stellar age in agreement with previous work. However, a stronger (>4sigma) correlation with alpha/Fe is also found. These correlations indicate that galaxies with effective radii smaller than those predicted by the FP have stellar populations systematically older and with alpha over-abundances larger than average, for their sigma_0. Including alpha/Fe as a fourth parameter in the FP, the total scatter decreases from 0.088 dex to 0.075 dex and the estimated intrinsic scatter decreases from 0.068 dex to 0.049 dex. Thus, variations in alpha/Fe account for >> 30% of the total variance around the FP, and >> 50% of the estimated intrinsic variance. This result indicates that the distribution of galaxies around the FP are tightly related to the enrichment, and hence to the timescale of star-formation. Our results appear to be consistent with the merger hypothesis for the formation of ellipticals which predicts that a significant fraction of the scatter is due to variations in the importance of dissipation in forming merger remnants of a given mass.

description:
Background: Mobility is acknowledged in the literature as the highest predictorof pressure ulcer development, however most of clinical studies assess mobilitysubjectively. The few studies that have analysed mobility objectively usingtechnology have the limitation of not measuring small postural changes, whichare important for pressure relief. A more comprehensive analysis of mobility,including all types of movement is needed to better understand mobility andpressure ulcer development, and to further correlate it with other risk factors.Therefore, a quantitative, prospective, non-experimental study among the elderlypopulation was undertaken.Aim: The primary objective of the study was to explore how activity and mobility,along with other risk factors lead to pressure ulcer development in older personscared for in long-term facilities. The secondary objectives of the study were firstlyto report pressure ulcer incidence among the study participants using visual skinassessment and sub-epidermal moisture (SEM) measurement. Secondly, toexplore mobility in healthy volunteers using a mobility sensor in order to compareto mobility levels of older people cared for in long-term settings.Methods: Ethical approval was received. The chosen explanatory variables wereincluded as they are common to the three most widely used risk assessment tools(Waterlow, Norton and Braden), namely, mobility, activity, nutritional status andincontinence. Following statistical advice and after the results of the pilot study of48 participants, the sample size was recalculated based on the two causal factorsthat varied over the 20-day follow-up, namely mobility and activity. Therefore, atotal of 150 participants were included. The pilot study also identified the need toinclude healthy participants to better determine mobility among a healthypopulation, in order to enhance the understanding of the older participants’movements. Following ethical approval, a total of 22 healthy participants wereincluded and their mobility were assessed over a 2-night period, using the samemotion sensor employed within the main study.

description: In the past few years, high-temperature annealing of AlN has become a proven method for providing AlN layers with low dislocation densities. Herein, the example of Al0.77Ga0.23N is used to investigate whether annealing can also improve the material quality of the ternary alloy. A detailed analysis of the influence of annealing temperature on structural and optical material properties is presented. It is found that with increasing annealing temperature, the threading dislocation density can be lowered from an initial value of 6.0 × 109 down to 2.6 × 109 cm−2. Ga depletion at the AlGaN surface and Ga diffusion into the AlN buffer layer are observed. After annealing, the defect luminescence between 3 and 4 eV is increased, accompanied by an increase in the oxygen concentration by about two orders of magnitude. Furthermore, due to annealing optical absorption at 325 nm (3.8 eV) occurs, which increases with increasing annealing temperature. It is assumed that the reason for this decrease in ultraviolet (UV) transmittance is the increasing number of vacancies caused by the removal of group-III and N atoms from the AlGaN lattice during annealing.

description: We lift the recently proposed theories of higher-spin self-dual Yang-Mills (SDYM) and gravity (SDGR) to the twistor space. We find that the most natural room for the twistor formulation of these theories is not in the projective, but in the full twistor space, which is the total space of the spinor bundle over the 4-dimensional manifold. In the case of higher-spin extension of the SDYM we prove an analogue of the Ward theorem, and show that there is a one-to-one correspondence between the solutions of the field equations and holomorphic vector bundles over the twistor space. In the case of the higher-spin extension of SDGR we show show that there is a one-to-one correspondence between solutions of the field equations and Ehresmann connections on the twistor space whose horizontal distributions are Poisson, and whose curvature is decomposable. These data then define an almost complex structure on the twistor space that is integrable.

description: We present simple protocols for oblivious transfer and password-based identification which are secure against general attacks in the noisy-quantum-storage model as defined in [KWW09]. We argue that a technical tool from [KWW09] suffices to prove security of the known protocols. Whereas the more involved protocol for oblivious transfer from [KWW09] requires less noise in storage to achieve security, our "canonical" protocols have the advantage of being simpler to implement and the security error is easier control. Therefore, our protocols yield higher OT-rates for many realistic noise parameters. Furthermore, the first proof of security of a direct protocol for password-based identification against general noisy-quantum-storage attacks is given.

title: The Local Interest as a Consideration in the Planning of Highway Construction in the Canyonlands Region of Southeastern Utah
Creators: name: Barry, Robert L.
Publisher: name: Utah State University
Year: 1973

description: An examination was conducted of the potential of proposed highway construction for serving the needs and interests of the population of the Canyonlands Region of southeastern Utah. The history of the highway development issue in the region was first examined with special attention given to the local position on the issue as expressed by local government spokesmen. Next, the total system of development proposals for the region was divided into four sections using criteria of area served and degree of controversy. A map analysis was conducted to determine how these four separate proposals would serve transportation needs of the region. Travel data for 1971 Utah nonresident travelers were utilized to determine present tourism travel and expenditure patterns within the region. Projections were made as to how these patterns would be altered by the four proposals and of how such alterations would affect the tourism industry in the five Canyonlands counties. Region resident perceptions of how the proposals would serve transportation, tourism development, and general economic needs of the region, its counties, and communities were obtained from 231 questionnaires. The same instruments also examined resident preferences for route development.
The analyses indicated that the proposed developments will have few effects on regional transportation needs, and that the impact on the tourism industry will be substantial in some areas within the region and negligible in others. Resident expectations of which proposals would best meet county, community, and household needs were generally realistic. Residents assigned priority for development to proposals anticipated to best serve needs at these levels. Regional needs were not clearly perceived and were not important in determining development preferences. The position on the highway development issue taken by local government leaders distorts the views of residents but does so in a way which generally serves the local interest.

description: Pulsar timing arrays (PTA) are a promising probe to the cosmologically novel nanohertz gravitational wave (GW) regime through the stochastic GW background. In this work, we consider subluminal GW modes as a possible source of correlations in a PTA, utilizing the public code PTAfast and the 12.5 years correlations data by NANOGrav, which we hypothesize are sourced by GWs. Our results show no evidence in support of tensor- or vector-induced GW correlations in the data, and that vector correlations are disfavored. This places an upper bound to the graviton mass, $m_{\rm g} \lesssim 10^{-22}$ eV, characteristic of the PTA GW energy scale.

description: Measurement is the only part of a general quantum system that has yet to be characterized experimentally in a complete manner. Detector tomography provides a procedure for doing just this; an arbitrary measurement device can be fully characterized, and thus calibrated, in a systematic way without access to its components or its design. The result is a reconstructed POVM containing the measurement operators associated with each measurement outcome. We consider two detectors, a single-photon detector and a photon-number counter, and propose an easily realized experimental apparatus to perform detector tomography on them. We also present a method of visualizing the resulting measurement operators.

description: Much has been written on reciprocity laws in number theory and their connections with group representations. In this paper we explore more on these connections. We prove a "reciprocity Law" for certain specific representations of semidirect products of two cyclic groups which is in complete analogy with classical reciprocity laws in number theory. In fact, we show that the celebrated quadratic reciprocity law is a direct consequence of our main theorem applied to a specific group. As another consequence of our main theorem we also recover a classical theorem of Sylvester. Our main focus is on explicit constructions of representations over sufficiently small fields. These investigations give further evidence that there is still much unexplored territory in connections between number theory and group representations, even at an elementary level.

title: An Analysis of the Outdoor Recreation Resource and Its Development in the Canyon Country of San Juan and Grand Counties, Utah
Creators: name: Royer, Lawrence E.
Publisher: name: Utah State University
Year: 1968

description: The wild lands recreational resources of the canyon country of southeastern Utah were analyzed within an evaluation framework specific to the region. Patterns of recreation development were established and recommendations for planning were submitted.
The study area was found to be richly endowed with environmental recreation resources and opportunities. Contributing environmental factors included the uniqueness, diversity, configuration, and/or abundance of the scenic, water, climatic, and primitive resources. An unusually wide spectrumquality opportunities were present.
Planning and development were inconsistent with the expression of the environmental resources. A lack of coordination among the responsible public agencies, disparities in allocation of planning and development priorities, and the failure of planning to derive maximum utility from the resources were evident. Deficiencies of existing development can be easily corrected because of the embryonic state of development.
Recommendations pertinent to coordination among agencies, master planning, facilities development, land classification, wilderness allocation, interpretation, and scenic drives were proposed.

description: Spectral lag, the time difference between the arrival of high-energy and low-energy photons, is a common feature in Gamma-ray Bursts (GRBs). Norris et al. 2000 reported a correlation between the spectral lag and the isotropic peak luminosity of GRBs based on a limited sample. More recently, a number of authors have provided further support for this correlation using arbitrary energy bands of various instruments. In this paper we report on a systematic extraction of spectral lags based on the largest Swift sample to date of 31 GRBs with measured redshifts. We extracted the spectral lags for all combinations of the standard Swift hard x-ray energy bands: 15-25 keV, 25-50 keV, 50-100 keV and 100-200 keV and plotted the time dilation corrected lag as a function of isotropic peak luminosity. The mean value of the correlation coefficient for various channel combinations is -0.68 with a chance probability of ~ 0.7 x 10^{-3}. In addition, the mean value of the power-law index is 1.4 +/- 0.3. Hence, our study lends support for the existence of a lag-luminosity correlation, albeit with large scatter.

We call our procedure TopoTests. The presented tests work for samples of arbitrary dimension, having comparable power to the state-of-the-art tests in the one-dimensional case. It is demonstrated that the type I error of TopoTests can be controlled and their type II error vanishes exponentially with increasing sample size. Extensive numerical simulations of TopoTests are conducted to demonstrate their power for samples of various sizes.

description: Several challenges (e.g., sexism, parental leave, the glass ceiling, etc.) disproportionately affect women in academia (and beyond), and thus perpetuate the leaky pipeline metaphor for women who opt-out of an academic career. Although this pattern can be seen at all levels of the academic hierarchy, a critical time for women facing such challenges is during the postdoctoral stage, when personal life transitions and professional ambitions collide. Using a social identity approach, we explore factors affecting the mental health of postdoctoral women, including identity development (e.g., as a mother, a scientist) and lack of control (uncertainty about one’s future personal and professional prospects), which likely contribute to the leak from academia. In this mixed-method research, Study 1 comprised interviews with postdoctoral women in North America (n = 13) and Europe (n = 8) across a range disciplines (e.g., psychology, physics, political science). Common themes included the negative impact of career uncertainty, gender-based challenges (especially sexism and maternity leave), and work-life balance on mental and physical health. However, interviewees also described attempts to overcome gender inequality and institutional barriers by drawing on support networks. Study 2 comprised an online survey of postdoctoral women (N = 146) from a range of countries and academic disciplines to assess the relationships between social identification (e.g., disciplinary, gender, social group), perceived control (i.e., over work and life), and mental health (i.e., depression, anxiety, stress, and life satisfaction). Postdoctoral women showed mild levels of stress and depression, and were only slightly satisfied with life. They also showed only moderate levels of perceived control over one’s life and work. However, hierarchical regression analyses revealed that strongly identifying with one’s discipline was most consistently positively associated with both perceived control and mental health. Collectively, these findings implicate the postdoctoral stage as being stressful and tenuous for women regardless of academic background or nationality. They also highlight the importance of disciplinary identity as a potentially protective factor for mental health that, in turn, may diminish the rate at which postdoctoral women leak from the academic pipeline.

description: In this paper, we have explored the field equations of f(T, B) gravity as an extension of teleparallel gravity in an isotropic and homogeneous space time. In the basic formalism developed, the dynamical parameters are derived by incorporating the power law and exponential scale factor function. The models are showing accelerating behaviour and approaches to $Λ$CDM at late time.The present value of the equation of state parameter for both the cases are obtained to be in accordance with the range provided by cosmological observations. The geometrical parameters and the scalar field reconstruction are performed to assess the viability of a late time accelerating Universe. Further the stability of both the models are presented. It has been observed that both the models are parameters dependent. Since most of the geometrically modified theories of gravity are favouring the violation of strong energy condition, we have derived the energy conditions both for the power law and exponential model. In both the models, the violation of strong energy condition established.

description: A new azobenzene-thiophene molecular switch is designed, synthesized and used to form self-assembled monolayers (SAM) on gold. An "on/off" conductance ratio up to 7x1E3 (with an average value of 1.5x1E3) is reported. The "on" conductance state is clearly identified to the cis isomer of the azobenzene moiety. The high "on/off" ratio is explained in terms of photo-induced, configuration-related, changes in the electrode-molecule interface energetics (changes in the energy position of the molecular orbitals with respect to the Fermi energy of electrodes) in addition to changes in the tunnel barrier length (length of the molecules). First principles DFT calculations demonstrate a better delocalization of the frontier orbitals, as well as a stronger electronic coupling between the azobenzene moiety and the electrode for the cis configuration over the trans one. Measured photoionization cross-sections for the molecules in the SAM are close to the known values for azobenzene derivatives in solution.

description: Constant potential method molecular dynamics simulation (CPM MD) enables the accurate modelling of atomistic electrode charges when studying the electrode-electrolyte interface at the nanoscale. Here we extend the theoretical framework of CPM MD to the case in which the total charge of each conductive electrode is controlled, instead of their potential differences. We show that the resulting thermodynamic ensemble is distinct from that sampled in with a fixed potential difference, but rigorously related as conjugate ensembles. This theoretical correspondence, which we demonstrate using simulations of an ionic liquid supercapacitor, underpins the success of recent studies with fixed total charges on the electrodes. We show that equilibration is usefully sped up in this ensemble and outline some potential applications of these simulations in future.

description: Magnetic imaging with nitrogen-vacancy (NV) spins in diamond is becoming an established tool for studying nanoscale physics in condensed matter systems. However, the optical access required for NV spin readout remains an important hurdle for operation in challenging environments such as millikelvin cryostats or biological systems. Here, we demonstrate a scanning-NV sensor consisting of a diamond nanobeam that is optically coupled to a tapered optical fiber. This nanobeam sensor combines a natural scanning-probe geometry with high-efficiency through-fiber optical excitation and readout of the NV spins. We demonstrate through-fiber optically interrogated electron spin resonance and proof-of-principle magnetometry operation by imaging spin waves in an yttrium-iron-garnet thin film. Our scanning-nanobeam sensor can be combined with nanophotonic structuring to control the light-matter interaction strength, and has potential for applications that benefit from all-fiber sensor access such as millikelvin systems.

description: Twenty selected Agropyron elongatum clones were evaluated in parent and progeny nurseries with each clone represented by 560 progenies. Agronomic characters evaluated on the progenies included degree of erectness, three height measurements, and green weight data. Correlations were calculated between the seed yields of the progenies and the forage yield of the parents. General combining ability was determined for the 20 clones.
The clonal source of variation for erectness was high. More variation existed within clones for green weight than for any other character studied. Two specific clones exhibited better over-all general combining ability than the others. Successive seed yields on the same nursery were highly correlated, whereas no correlation was found between progeny forage and parent seed yields.

description: Using Radioautography 14C simazine, 14C EPTC, 14C 2,4-D, 1414 DCPA and 14C pyrazon absorption by seeds of bean (Phaseolus vulgaris L.), squash (Cucurbita maxima), corn (Zea mays), onion (Allium cepa) and oat (Avena sativa) was studied. Simazine, EPTC, 2,4-D and pyrazon were absorbed through the seed coat of bean, squash, corn and onion, the amount increasing with time. Little DCPA was absorbed by seeds of bean, squash, onion and oat. Distribution and translocation of 14C simazine, 14C EPTC and 14C pyrazon occurred in the young plants of bean, squash, corn and onion. Simazine and pyrazon accumulated in the leaf margins of bean, EPTC and pyrazon were found in the cotyledon margins of squash, and pyrazon was found in the coleoptile tips and leaf tips of corn. The translocation of 14C 2,4-D in bean, onion and squash showed a characteristic fixation along the path of the translocation. Very little translocation or distribution of 14C DCPA were found in bean, squash, onion or oat.
In bean leaf, 14C pyrazon was absorbed and moved acropetally in the apoplast. Basipetal movement of 14C pyrazon was limited.
Microadioautography was used to determine the tissues involved in the translocation of 14C simazine, 14C EPTC, 14C 2,4-D and 14C pyrazon. Simazine and EPTC were found in the vascular bundle tissues of bean leaf. EPTC was found in the cortex of squash root. 2,4-D was found in the vascular tissues and surrounding the vascular bundle of squash cotyledon and onion hypocotyl. Pyrazon was found intercellularly and intracellularly in bean cotyledon.

description: We consider a one-dimensional mesoscopic quantum ring filled with spinless electrons and threaded by a magnetic flux, which carries a persistent current at zero temperature. The interplay of Coulomb interactions and a single on-site impurity yields a non-trivial dependence of the persistent current on the size of the ring. We determine numerically the asymptotic power law for systems up to 32000 sites for various impurity strengths and compare with predictions from Bethe Ansatz solutions combined with Bosonization. The numerical results are obtained using an improved functional renormalization group (fRG) method. We apply the density matrix renormalization group (DMRG) and exact diagonalization methods to benchmark the fRG calculations. We use DMRG to study the persistent current at low electron concentrations in order to extend the validity of our results to quasi-continuous systems. We briefly comment on the quality of calculated fRG ground state energies by comparison with exact DMRG data.

title: Effect of Gibberellic Acid and Chilling on Nucleic Acids During Germination of Dormant Peach Seed
Creators: name: Lin, Yuh-nan
Publisher: name: Utah State University
Year: 1968

description: A study of nucleic acid changes influenced by gibberellic acid and chilling treatments in peach seed was performed in an attempt to reach a better understanding of the mechanism involved in breaking seed dormancy.
Gibberellic acid and the chilling treatment increased the RNA content. These two treatments which break dormancy also increased RNA, suggesting a similar mechanism involving RNA. Chilled seeds contained more RNA than did the gibberellic acid treated seeds.
DNA content remained unchanged regardless of treatment.
Dry seed had a greater ribonuclease activity than with soaked seeds. Enzyme changes did not correlate well with the RNA content in gibberellic treated seeds.
Deoxyribonuclease activity was higher in dry seed than with soaked seeds. Enzyme activity change did not correlate well with the DNA content.
The phosphorus content of the seed in regard to the gibberllic acid and chilling treatments was difficult to evaluate. There were no major relationships established. Phosphorus in the methanol fraction from the chilled seed increased some as the storage period increased.

description: By creating and analyzing the two dimensional gas temperature and abundance maps of the RGH 80 compact galaxy group with the high-quality Chandra data, we detect a high-abundance ($\simeq 0.7$ $Z_\odot$) arc, where the metal abundance is significantly higher than the surrounding regions by $\simeq 0.3$ Z_\odot$. This structure shows tight spatial correlations with the member galaxy PGC 046529, as well as with the arm-like feature identified on the X-ray image in the previous work of Randall et al. (2009). Since no apparent signature of AGN activity is found associated with PGC 046529 in multi-band observations, and the gas temperature, metallicity, and mass of the high-abundance arc resemble those of the ISM of typical early-type galaxies, we conclude that this high-abundance structure is the remnant of the ISM of PGC 046529, which was stripped out of the galaxy by ram pressure stripping due to the motion of PGC 046529 in RGH 80. This novel case shows that ram pressure stripping can work efficiently in the metal enrichment process in galaxy groups, as it can in galaxy clusters.

title: Benefit/Cost Variables and Comparative Recreation Use Patterns of Wilderness and Non-Wilderness Areas
Creators: name: Christy, Kim S.
Publisher: name: Utah State University
Year: 1988

description: This paper examines formal wilderness designation and is presented in two parts. The first section offers a general classification and comprehensive review of the benefit and cost variables associated with wilderness designation and management. The second section investigates recreation use, which society has historically perceived to be the highest valued element in the network of wilderness benefits.
Variables associated with the benefits of wilderness designation are presented under three major categories: 1) naturalness preservation, 2) solitude or primitive and unconfined types of recreation, and 3) special features of scientific, educational, scenic, or historic value.
Costs attributed to wilderness designation are presented under two major categories: 1) administration/general management costs and 2) opportunity costs.
The second section of this thesis establishes growth rate comparisons of wilderness and non-wilderness recreation use on United States Forest Service lands in Utah, the Intermountain Region, and the overall national Forest Service system from 1967 to 1986. The High Uintas Wilderness area was also analyzed for its use over the same twenty-year period. Data used to measure recreational use at these levels was obtained from United States Forest Service Recreation Information Management records and are measured in recreational visitor days. Growth rate comparisons are measured with respect to recreation use in general terms as well as on a per acre basis at all levels examined.
Because of general trend discrepancies in recreation use over the twenty-year study period, growth rate estimates of recreation use at all levels are also measured with respect to two separate time periods--1967 to 1976 and 1977 to 1986. This analysis shows that non-wilderness/ primitive recreation use per acre increased during the last decade at all levels examined, whereas wilderness/primitive .recreation use per acre showed marked declines during the same period.
Growth rate estimates established on a per acre basis provide a general indication of the marginal value of wilderness and non-wilderness recreation use. This thesis shows that, with respect to recreation use, marginal utility has diminished in designated wilderness since 1977. In contrast, this research also infers that the marginal value for non-wilderness recreation use has increased. These findings suggest that, from a recreation perspective, adding wilderness areas to the National Wilderness Predervation System is unwarranted.

Superconformal invariants for scattering amplitudes in N=4 SYM theory

description: Recent studies of scattering amplitudes in planar N=4 SYM theory revealed the existence of a hidden dual superconformal symmetry. Together with the conventional superconformal symmetry it gives rise to powerful restrictions on the planar scattering amplitudes to all loops. We study the general form of the invariants of both symmetries. We first construct an integral representation for the most general dual superconformal invariants and show that it allows a considerable freedom in the choice of the integration measure. We then perform a half-Fourier transform to twistor space, where conventional conformal symmetry is realized locally, derive the resulting conformal Ward identity for the integration measure and show that it admits a unique solution. Thus, the combination of dual and conventional superconformal symmetries, together with invariance under helicity rescalings, completely fixes the form of the invariants. The expressions obtained generalize the known tree and one-loop superconformal invariants and coincide with the recently proposed coefficients of the leading singularities of the scattering amplitudes as contour integrals over Grassmannians.

The impact of United States final demand on Canadian production : an input-output study
Creators: name: Horner, Leslie William Keith
Publisher: name: University of British Columbia
Year: 2011

description: In this thesis, the impact of United States final demand on Canadian demand and production is investigated using an interregional input-output model. First, the simple Leontief input-output model is considered. It is a disaggregated model of the production sector of an economy that allows a set of industry outputs to be expressed as a function of a corresponding set of industry final demands. It improves on other output determination models by admitting that industry outputs are interdependent. However, it requires the assumption of fixed production coefficients. Next, the extension of the model to incorporate interregional trade is considered. Several models are described that determine the industry outputs of each of a group of regions as functions of the industry final demands in all regions. A model is selected that differs from all of these, not in its essential algebraic structure, but in the method by which it is applied. In the simplified form in which it is used in this study, it requires that Canada's merchandise exports to the United States be reclassified according to the industry schemes of the Canadian and American input-output tables. The main advantage of the model over the other interregional models considered is that it allows the input-output tables of the individual regions to be used in their original form. Using the model, two questions are investigated. First, how do equal expenditures on the various components of United States final demand - Consumption, Fixed investment, Federal Government purchases, and State and local government purchases -compare in their impact on Canadian demand and output ? Second, in the period 1956 to I960, did variation in the level and pattern of United States final demand tend to aggravate fluctuations in Canadian demand, output, and net exports ? Several results are obtained. With reference to the first question, Investment expenditure is found to have considerably greater impact on Canadian demand and production than any of the other components of United States demand. The wide disparity in impact is largely explained by the concentration of Canadian exports to the United States on a few commodities. Concerning the second question, it is concluded that variations in both the level and pattern of United States final demand helped to generate fluctuations in the growth of Canadian demand and output. By contrast, the fluctuation of United States final demand tended to damp fluctuations in Canadian net exports.

description: The United States, much like other countries around the world, faces significant obstacles to achieving a rapid decarbonization of its economy. Crucially, decarbonization disproportionately affects the communities that have been historically, politically, and socially embedded in the nation's fossil fuel production. However, this effect has rarely been quantified in the literature. Using econometric estimation methods that control for unobserved heterogeneity via two-way fixed effects, spatial effects, heterogeneous time trends, and grouped fixed effects, we demonstrate that mine closures induce a significant and consistent contemporaneous rise in the unemployment rate across US counties. A single mine closure can raise a county's unemployment rate by 0.056 percentage points in a given year; this effect is amplified by a factor of four when spatial econometric dynamics are considered. Although this response in the unemployment rate fades within 2-3 years, it has far-reaching effects in its immediate vicinity. Furthermore, we use cluster analysis to build a novel typology of coal counties based on qualities that are thought to facilitate a successful recovery in the face of local industrial decline. The combined findings of the econometric analysis and typology point to the importance of investing in alternative sectors in places with promising levels of economic diversity, retraining job seekers in places with lower levels of educational attainment, providing relocation (or telecommuting) support in rural areas, and subsidizing childcare and after school programs in places with low female labor force participation due to the gendered division of domestic work.
