description: Let $\mathsf{PreOrd}(\mathbb C)$ be the category of internal preorders in an exact category $\mathbb C$. We show that the pair $(\mathsf{Eq}(\mathbb C), \mathsf{ParOrd}(\mathbb C))$ is a pretorsion theory in $\mathsf{PreOrd}(\mathbb C)$, where $\mathsf{Eq}(\mathbb C)$ and $\mathsf{ParOrd}(\mathbb C)$) are the full subcategories of internal equivalence relations and of internal partial orders in $\mathbb C$, respectively. We observe that $\mathsf{ParOrd}(\mathbb C)$ is a reflective subcategory of $\mathsf{PreOrd}(\mathbb C)$ such that each component of the unit of the adjunction is a pullback-stable regular epimorphism. The reflector $F:\mathsf{PreOrd}(\mathbb C)\to \mathsf{ParOrd}(\mathbb C)$ turns out to have stable units in the sense of Cassidy, Hébert and Kelly, thus inducing an admissible categorical Galois structure. In particular, when $\mathbb C$ is the category $\mathsf{Set}$ of sets, we show that this reflection induces a monotone-light factorization system (in the sense of Carboni, Janelidze, Kelly and Paré) in $\mathsf{PreOrd}(\mathsf{Set})$. A topological interpretation of our results in the category of Alexandroff-discrete spaces is also given, via the well-known isomorphism between this latter category and $\mathsf{PreOrd}(\mathsf{Set})$.

description: The main purpose in the present paper is to build a Hamiltonian theory for fields which is consistent with the principles of relativity. For this we consider detailed geometric pictures of Lepage theories in the spirit of Dedecker and try to stress out the interplay between the Lepage-Dedecker (LP) description and the (more usual) de Donder-Weyl (dDW) one. For instance the Legendre transform in the dDW approach is replaced by a Legendre correspondence in the LP theory, while ignoring singularities whenever the Lagrangian is degenerate. Moreover we show that there exist two different definitions of the observable (n-1)-forms which allows one to construct observable functionals by integration (which correspond to two different points of view: generalizing the law {p,q} = 1 or the law dF\dt = {H,F}), oddly enough we prove that these two definitions coincides only in the LP situation. Finally other contributions concerning this subject and examples are also given.

description: Many models of physics beyond the Standard Model predict a strong first-order phase transition (SFOPT) in the early Universe that leads to observable gravitational waves (GWs). In this paper, we propose a novel method for presenting and comparing the GW signals that are predicted by different models. Our approach is based on the observation that the GW signal has an approximately model-independent spectral shape. This allows us to represent it solely in terms of a finite number of observables, that is, a set of peak amplitudes and peak frequencies. As an example, we consider the GW signal in the real-scalar-singlet extension of the Standard Model (xSM). We construct the signal region of the xSM in the space of observables and show how it will be probed by future space-borne interferometers. Our analysis results in sensitivity plots that are reminiscent of similar plots that are typically shown for dark-matter direct-detection experiments, but which are novel in the context of GWs from a SFOPT. These plots set the stage for a systematic model comparison, the exploration of underlying model-parameter dependencies, and the construction of distribution functions in the space of observables. In our plots, the experimental sensitivities of future searches for a stochastic GW signal are indicated by peak-integrated sensitivity curves. A detailed discussion of these curves, including fit functions, is contained in a companion paper [2002.04615]. The data and code that we used in our analysis can be downloaded from Zenodo [https://doi.org/10.5281/zenodo.3699415].

description: The aim of this study is to examine the effect that the country of design and the country of manufacture has on the perceived quality of a product, and the role of involvement as a moderating variable. The conceptual framework has been tested using laboratory experiments that included a 2x2x2 between the subject’s factorial designs. Participants were assigned by using a randomization method and data was analyzed using a one-way and two-ways ANOVA. The results indicated consumers’ involvement, as a moderating variable, limited the strength of the country of design and the perceived quality’s relationship as this relationship is found to be stronger in circumstances where the consumers’ involvement was greater than in the less involved group’s condition. However, consumers’ involvement did not have any role as a moderating variable in the relationship between the country of manufacture and the perceived quality.

description: Placing cattle in feedlots for finishing is a common practice in the United States and 14.5% of the national herd was placed on feed in 2015. The objective of this poster is to document the influence of technology and cattle source on the performance characteristics of fed cattle. Advances in production practices including improved genetics, preconditioning and health treatments have yielded distinct trends that have led to a higher level of beef output. Consumer preferences have also driven feedlot applications and a comprehensive review of the sector will provide a reference for anticipating new directions in the industry. This research is part of my master’s thesis, which examines the value of background information for individual animals in the beef supply chain. Discerning the effects of unique production methods will aid in identifying which factors are the most influential and valuable for production. The objective is to use these results to evaluate the potential value and market for traceable information within the beef industry.

description: The multi-particle production at high energy neutrino- nucleon collisions are investigated through the analysis of the data of the experiment CERN-WA-025 at neutrino energy less than 260GeV and the experiments FNAL-616 and FNAL-701 at energy range 120-250 GeV. The general features of these experiments are used as base to build a hypothetical model that views the reaction by a Feynman diagram of two vertices. The first of which concerns the weak interaction between the neutrino and the quark constituents of the nucleon. At the second vertex, a strong color field is assumed to play the role of particle production, which depend on the momentum transferred from the first vertex. The wave function of the nucleon quarks are determined using the variation method and relevant boundary conditions are applied to calculate the deep inelastic cross sections of the virtual diagram.

description: The elliptic flow of muons from the decay of charm and bottom hadrons is measured in $pp$ collisions at $\sqrt{s}=13$ TeV using a data sample with an integrated luminosity of 150 pb$^{-1}$ recorded by the ATLAS detector at the LHC. The muons from heavy-flavor decay are separated from light-hadron decay muons using momentum imbalance between the tracking and muon spectrometers. The heavy-flavor decay muons are further separated into those from charm decay and those from bottom decay using the distance-of-closest-approach to the collision vertex. The measurement is performed for muons in the transverse momentum range 4-7 GeV and pseudorapidity range $|η|<2.4$. A significant non-zero elliptic anisotropy coefficient $v_{2}$ is observed for muons from charm decays, while the $v_{2}$ value for muons from bottom decays is consistent with zero within uncertainties.

description: Abstract: Cystic fibrosis (CF) is an autosomal recessive disease caused by mutations in the CFTR gene. The 3272–26A>G and 3849+10kbC>T CFTR mutations alter the correct splicing of the CFTR gene, generating new acceptor and donor splice sites respectively. Here we develop a genome editing approach to permanently correct these genetic defects, using a single crRNA and the Acidaminococcus sp. BV3L6, AsCas12a. This genetic repair strategy is highly precise, showing very strong discrimination between the wild-type and mutant sequence and a complete absence of detectable off-targets. The efficacy of this gene correction strategy is verified in intestinal organoids and airway epithelial cells derived from CF patients carrying the 3272–26A>G or 3849+10kbC>T mutations, showing efficient repair and complete functional recovery of the CFTR channel. These results demonstrate that allele-specific genome editing with AsCas12a can correct aberrant CFTR splicing mutations, paving the way for a permanent splicing correction in genetic diseases.

description: This study was designed to determine if a relationship existed between corn (Zea mays) and soybean (Glycine max) yields and climate factors in West Tennessee from 1955 to 2013. Yield data was obtained from National Agricultural Statistics Service (NASS) annual crop surveys for the twenty one counties in United States Department of Agriculture (USDA) West Tennessee and Delta Districts. Climate data for was obtained from National Climatic Data Center (NCDC). Only climate data from April through October was used in calculations to more accurately reflect corn and soybean growing seasons. Correlations, linear regressions, and multiple regressions were developed to compare crop yields with climate factors for the year as well as three phases of the crop production process (planting, growing, and harvesting). Significant relationships were found to exist between corn yield and minimum temperature (r = 0.32; P = .01), precipitation (r = 0.29; P = .26), Palmer Z-Index (r = 0.26; P = .47), and one month Standardized Precipitation Index (r = 0.26; P = .049). Significant relationships were found between soybean yield and maximum temperature (r = -0.32; P = .01), precipitation (r = 0.43; P < 0.001), Palmer Drought Severity Index (r = 0.28; P = .03), Palmer Z-Index (r = 0.43; P < .001), and one month Standardized Precipitation Index (r = 0.46; P < .001). The study found that yields were dependent on multiple climatic factors due to the abundance of significant multiple regression models compared to linear regression models. However, West Tennessee corn and soybean yields were not statistically influenced by average temperature or climate factors during the planting stage of production. Overall, growing season temperature and precipitation factors were important and will continue to impact corn and soybean yields in West Tennessee.

description: This paper examines the general knowledge of consumers regarding organic food and determines their willingness to pay more for it. Data was collected on a random sample of grocery shoppers in the state of Tennessee. The study reveals most of the respondents had a fair knowledge of what organic food was. The number of respondents who had never purchased organic food was found to be only slightly higher than the number who purchase it. A binary logistic regression found income and Environmental concern to be factors that effectively determine willingness to pay more for organic food.

description: We study the breakup of a liquid jet a few nanometers in diameter, based on a stochastic differential equation derived recently by Moseler and Landman [Science {\bf 289}, 1165 (2000)]. In agreement with their simulations, we confirm that noise qualitatively changes the characteristics of breakup, leading to symmetric profiles. Using the path integral description, we find a self-similar profile that describes the most probable breakup mode. As illustrated by a simple physical argument, noise is the driving force behind pinching, speeding up the breakup to make surface tension irrelevant.

description: The literature on choice experiments has been dealing with ways to refine preference elicitation from subjects and predictive power of models. Technological advances such as eye tracking has improved our understanding on how much of the attributes and attribute levels presented to participants is being considered in the decision making process in these kind of experiments. This study investigates subjects’ degree of attendance to attributes and how it influences their choices. The amount of time the subjects spent observing each attribute, relative to all available information on each choice set is used to estimate the attribute attendance. This indicates the revealed attendance to the attributes in the experiment. A simple econometric approach compares the parameter estimates from revealed attribute attendance adjusted models using data from an eye tracking device and a model endogenously inferring the probabilities of using information from each attribute in the choice. The results show that the assumption that participants use all the available information to make their decisions produces significant differences in the parameter estimates, leading to potential bias. The results also illustrate that model fit and predictive power is greatly increased by using revealed attendance levels using eye tracking measures. The most significant improvement however, is to endogenously infer attribute attendance; even more so with revealed attendance indicators.
Maxwell's fisheye lens as efficient power coupler between dissimilar photonic crystal waveguides

Subjects: subject: Optics (physics.optics)

description: The imaging properties of the Maxwell's fisheye (MFE) lens makes it a viable candidate to implement power coupling between different types of waveguides. A coupler based on the MFE lens is designed to couple a square lattice photonic crystal to a triangular lattice one. The MFE lens is implemented as ring-based multilayer and graded photonic crystal (GPC) structures. The performance of the ring-based MFE lens is better than the GPC-based one in the C-band of optical communication. The proposed ring-based MFE coupler has a footprint of $3.62\times 3.62μm$ and covers the entire C and U bands. The S and L bands are partially covered. The average insertion loss of 0.1dB and the maximum return loss of -11dB in the C-band is achieved.

description: For a conformal theory it is natural to seek the conformal moduli space, M_c to which it belongs, generated by the exactly marginal deformations. By now we should have the tools to determine M_c in the presence of enough supersymmetry. Here it is shown that its dimension is determined in terms of a certain index. Moreover, the D-term of the global group is an obstruction for deformation, in presence of a certain amount of preserved supersymmetry. As an example we find that the deformations of the membrane (3d) field theory, under certain conditions, are in 35/SL(4,C). Other properties including the local geometry of M_c are discussed.

description: Funder: Wellcome Trust; doi: http://dx.doi.org/10.13039/100004440
description: Abstract: Background: Glioma is the most common intrinsic brain tumor and also occurs in the spinal cord. Activating EGFR mutations are common in IDH1 wild-type gliomas. However, the cooperative partners of EGFR driving gliomagenesis remain poorly understood. Results: We explore EGFR-mutant glioma evolution in conditional mutant mice by whole-exome sequencing, transposon mutagenesis forward genetic screening, and transcriptomics. We show mutant EGFR is sufficient to initiate gliomagenesis in vivo, both in the brain and spinal cord. We identify significantly recurrent somatic alterations in these gliomas including mutant EGFR amplifications and Sub1, Trp53, and Tead2 loss-of-function mutations. Comprehensive functional characterization of 96 gliomas by genome-wide piggyBac insertional mutagenesis in vivo identifies 281 known and novel EGFR-cooperating driver genes, including Cdkn2a, Nf1, Spred1, and Nav3. Transcriptomics confirms transposon-mediated effects on expression of these genes. We validate the clinical relevance of new putative tumor suppressors by showing these are frequently altered in patients’ gliomas, with prognostic implications. We discover shared and distinct driver mutations in brain and spinal gliomas and confirm in vivo differential tumor suppressive effects of Pten between these tumors. Functional validation with CRISPR-Cas9-induced mutations in novel genes Tead2, Spred1, and Nav3 demonstrates heightened EGFRvIII-glioma cell proliferation. Chemogenomic analysis of mutated glioma genes reveals potential drug targets, with several investigational drugs showing efficacy in vitro. Conclusion: Our work elucidates functional driver landscapes of EGFR-mutant gliomas, uncovering potential therapeutic strategies, and provides new tools for functional interrogation of gliomagenesis.

description: Microalgae is an attractive feedstock for sustainable biodiesel production. The harvesting step of microalgae needs technology, which saves energy and time. One of the low cost strategies for addressing this problem is the use of flocculation-sedimentation process as an initial step. The aim of the present study is to evaluate the flocculation-sedimentation of selected microalgae species grown in monoculture (Nannochloropsis sp.) and mixed cultures (South Coast of Yogyakarta) using modified chitosan. The effect of flocculant dosage and sedimentation time that might affect the percentage of microalgae cell removal was investigated. Chitosan has proved to be highly effective for dewatering of the microalgae, Nannochloropsis sp. and Yogyakarta mixed cultures, with the optimum flocculation efficiency reaching over 72.09 % (25 ppm of chitosan dosage; 10 min of sedimentation time) and 87.25 % (25 ppm of chitosan dosage; 30 min of sedimentation time) of biomass removal. The characteristics of chitosan in term of high positive charge density and long chains allow the microalgae to aggregate to form flocs and settle to the bottom due to gravitational effect.

description: The study identified the factors influencing the discontinuance of improved rice technologies in Nasarawa State of Central Nigeria. Multi-stage random sampling was purposely used to select eighty rice farmers from four rice-producing villages of the study area using structured interview schedule on the respondents. Statistical analysis involving frequency counts, means and percentage were used to satisfy objectives 1, 2, 3, and 4 while regression analysis was applied to satisfy objective 5. The results of the regression analysis showed that education and extension contact had significant but negative relationship at 5% level; while age had positive and significant relationship at 1% level with discontinuance of adoption of improved rice technologies. Farmers should be encouraged to participate in the on-going government rural literacy campaign while extension contact be enhanced to minimize discontinuance of improved rice technologies.

description: We present a peculiar transition triggered by infinitesimal dissipation in the interpolating Dicke-Tavis-Cummings model. The model describes a ubiquitous light-matter setting using a collection of two-level systems interacting with quantum light trapped in an optical cavity. In a previous work [Phys. Rev. Lett. 120, 183603 (2018)], dissipation was shown to extend a normal phase (dark state) into new regions of the model's parameter space. Harnessing Keldysh's action formalism to compute the response function of the light, we show that the normal phase does not merely spread but encompasses a transition between the old and the dissipation-stabilized regimes of the normal phase. This transition, however, solely manifests in the dynamical fluctuations atop the empty cavity, through stabilization of an excited state of the closed system. Consequently, we reveal that the fluctuations flip from being particlelike to holelike across this transition. This inversion is also accompanied by the behavior of the Liouvillian eigenvalues akin to exceptional points. Our work forges the way to discovering transitions in a wide variety of driven-dissipative systems and is highly pertinent for current experiments.

description: We investigated the proportion of crab-eating macaques in the diet of Komodo dragons and quantified the spatial habitat use between the species as a proxy for predation threat and in relation to prey availability due to ecotourism. In 2013, in Loh Buaya valley of Rinca Island, Komodo National Park, we conducted macroscopic identification of hairs, claws, dentition and osteological remains of consumed prey. For habitat use, we quantified the use of vertical strata by macaques through focal animal sampling. For Komodo dragons in the valley, macaques were a significant component of their diet (20.7%), ranking second after rusa deer (58.6%); the proportion of macaques we observed in the diet is much higher than in previous studies. An increased use of the forest floor by macaques at this site may increase their vulnerability as a prey species, especially in the daytime when tourist presence impacts the availability of other favoured prey species.

description: The angular drift of a laser beam is of particular concern in applications such as seeded free-electron lasers. A systematical study of the obliquely incident laser and electron beam interaction in an undulator is presented in this paper. Theoretical analysis and numerical simulations demonstrate that the interaction would imprint energy and angular modulations on the electron beam simultaneously. Compared with the normally incident pattern, the obliquely incident laser-electron interaction leads to reductions in the bunching factors of HGHG and EEHG. In the meanwhile, proactive applications of this multi-dimensional modulation technique may bring vitality to the field of laser-electron manipulation

description: We study natural supersymmetric scenarios with light right-handed neutrino superfields, and consider the possibility of having either a neutrino or a sneutrino as a dark matter candidate. For the former, we evaluate the possibility of having SUSY corrections on the $ν_4\toν_\ellγ$ decay rate, such that the NuStar bounds are relaxed. We find that corrections are too small. For sneutrino dark matter, we consider thermal and non-thermal production, taking into account freeze-out, freeze-in and super-WIMP mechanisms. For the non-thermal case, we find that the $\tildeν_R$ can reproduce the observed relic density by adjusting the R-sneutrino mass and Yukawa couplings. For the thermal case, we find the need to extend the model in order to enhance sneutrino annihilations, which we exemplify in a model with an extended gauge symmetry.

description: The watermelon and the green alfalfa are important crops in Morocco. The ripe fruit of the watermelon has a high nutritional value, rich in vitamin and mineral salts and used for medicinal purposes (kidneys and cleaning of the urinary tract). The alfalfa green is principally cultivated for livestock feed. A common problem in the production of watermelon and the alfalfa is the infestation by aphids. They transmit viruses of the tile to the plants. They are more likely to be a problem in the time costs. The study presents the effects of products Thyme, Oregano, Neem and their mixture on the aphids of watermelon in comparison with their effects on aphids of alfalfa green. The tests were conducted of the months from May to September on the aphids on the fields of watermelon and alfalfa green. It determines the percentage of deaths of aphids in function of the dose 1% and 5% for these products and the time 3, 5 and 7 hours after treatment. A comparison between the results obtained showed that the extract of Thyme is more active in watermelon and the Oregano is in alfalfa.
Determination of the strangeness contents of light-flavour isoscalars from its production rates in hadronic Z decays measured at LEP

description: A new phenomenological approach is suggested to determine the strangeness contents of light-flavour isoscalars. This approach is based on phenomenological laws of hadron production related to the spin, isospin, strangeness content and mass of the particles. The ``effective'' numbers of s and \bar{s} quarks in the isoscalar partners i_1 and i_2 are given by the nonstrange-strange mixing angle ϕ: k(i_1)=2\sin^2ϕand k(i_2)=2\cos^2ϕ. From the total production rates per hadronic Z decay of all light-flavour hadrons measured so far at LEP the values for k are found to be: k(η) \equiv 2-k(η^{\prime}) = 0.91 \pm 0.12, k(ϕ) \equiv 2-k(ω) = 1.94 \pm 0.09, k(f_2^{\prime}) \equiv 2-k(f_2) = 1.84 \pm 0.21 and k(f_0) = 0.09 \pm 0.13. Our results on the η--η^{\prime}, ω--ϕand f_2--f_2^{\prime} isoscalar mixing are consistent with the present experimental evidence. Quite remarkably, our value for k(η) corresponds to the singlet-octet mixing angle θ_P = -12.4^{\circ} \pm 3.5^{\circ}. The obtained strangeness content of the f_0(980) scalar/isoscalar is not consistent with the values supported by different model studies. However, taking the f_0(980) in our analysis with the mass of the bare state (K-matrix pole) f_0^{bare}(720 \pm 100), the mixing angle is found to be: |ϕ_S^{bare}| = 73^{\circ} \pm 7^{\circ} \pm 24^{\circ}, in good agreement with the prediction of the K-matrix analysis.

description: Design optimisation problems of window size in buildings with regard to energy saving and comfort criteria have been investigated many times. To indicate daylight availability and energy consumption in indoor spaces, a number of metrics have been proposed, but so far there is no convention on which daylight and energy metrics are preferred. Meanwhile, evolutionary techniques such like genetic algorithm have long been used to optimise parameters in building design. In the optimisation process, however, different metrics or objectives normally lead to different degrees of uncertainty of the obtained results. This article presents a study to determine the most appropriate metrics for the case of daylight optimisation in a reference office space, by comparing various daylight metrics and lighting energy demand indicators, using genetic algorithm to optimise the window-to-wall ratio (WWR) and the room interior reflectance. To determine the appropriate metrics, the optimisation results were classified based on their computational precision. It is found that maximising spatial useful daylight illuminance (sUDI)100∼2000lx,50%−sUDI>2000lx,50% leads to objective function values with the highest precision, while minimising annual lighting energy demand+sUDI>2000lx,50% gives the most robust input variables. Therefore, these two pairs of metrics are suggested as the most appropriate for optimising daylight in the particular space.

description: We present a study of photon-photon scattering in the mass range $W_{γγ} < 5$ GeV. We extend earlier calculations of this cross section for $W_{γγ}>$ 5 GeV into the low mass range where photoproduction of the pseudoscalar resonances $η$, $η^{'}(958)$ contributes to two-photon final states. We present the elementary photon-photon cross section as a function of diphoton mass $M_{γγ}$ arising from lepton and quark loop diagrams, and the visible cross section obtained with the gamma-gamma decay branching fractions of the resonances $η$, $η^{'}(958)$, $η_c(1S)$, $η_c(2S)$, $χ_{c0}(1P)$. We derive the corresponding cross sections in ultra-peripheral Pb-Pb collisions at $\sqrt{s_{NN}}$ = 5.02 TeV by folding the elementary cross section with the heavy-ion photon fluxes. We consider the dominating background of the two-photon final state which arises from gamma decays of photoproduced $π^{0}$-pairs. Such $π^{0}$-pairs contribute to the background when only two of the four decay photons are within the experimental acceptance, while the other two photons escape undetected. We reduce this background by applying cuts on asymmetries of transverse momenta of the two photons and indicate how the background can be further suppressed using a multivariate sideband analysis. We present the cross section for the signal and the background at midrapidity $|η|

description: Farmers have always lived in changing environments where uncertainty and disturbances are inevitable. Therefore, farmers need the ability to adapt to change in order to be able to maintain their farms. Experimentation is one way for farmers to learn and adapt, and may be a tool to build farm resilience. Farmers’ experiments as defined in this paper are activities where something totally or partially new is introduced at the farm and the feasibility of this introduction is evaluated. The theoretical framework applied to study farmers’ experiments is the concept of resilience. Resilience is the capacity of social-ecological systems to cope with change, and is a framework used to assess complex systems of interactions between humans and ecosystems. This paper explores to which extent farmers’ experimentation can help build farm resilience. In addition to arguments found in the literature, five organic farms in Eastern Austria are used to illustrate this potential. The farmers were interviewed in 2007 and 2008. The respective farmers all worked fulltime on their farms, were between 34 and 55 years old, and owned farms between 15 and 76 ha. These farmers experimented in ways that enhance resilience – at the farm and in the region. The outcome of experiments can be management changes, new insights, or technology that can be passed on and potentially be built into education and advisory institutions. To encourage farmers’ experiments, it is important to develop conditions that support farmers in their experimenting role.

description: In generic conformal field theories with $W_3$ symmetry, we identify a primary field $σ$ with rational Kac indices, which produces the full $\mathbb{Z}_3$ charged and neutral sectors by the fusion processes $σ\times σ$ and $σ\times σ^*$, respectively. In this sense, this field generalises the $\mathbb{Z}_3$ fundamental spin field of the three-state Potts model. Among the degenerate fields produced by these fusions, we single out a `parafermion' field $ψ$ and an `energy' field $\varepsilon$. In analogy with the Virasoro case, the exact curves for conformal dimensions $(h_σ,h_ψ)$ and $(h_σ,h_\varepsilon)$ are expected to give close estimates for the unitarity bounds in the conformal bootstrap analysis.

description: This paper describes the economic and social challenges faced by Enfield, a small town in rural northeastern North Carolina, and the efforts by the Center for Competitive Economies at the University of North Carolina at Chapel Hill to assist the community in a strategic economic development plan to address these challenges. In particular, the paper outlines the challenges and tensions between place-based versus people-based economic development approaches and how these tensions are generalizeable to other rural small towns. Lastly, the paper concludes that even the most effective economic development strategies may only impact the community marginally given the larger confluence of events in the broader region, such as general population loss due to outmigration, declining traditional industries, and stagnant regional economies.
