Opening Shops: Explanations for Resurgence in Right-to-Work Laws
Creators: name: Baehren, Hunter
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2018

description: Since 2011, the United States has experienced a resurgence in state-level right-to-work laws. The causes of this trend, however, have remained unexplored by social science literature. In this paper, I examine the introduction and passage of bills among state legislatures and test the respective explanatory power of demographics, partisanship, union membership, small business prevalence, and joblessness. After applying regression models to introduction and passage models respectively, I find evidence that GOP legislative control holds a positive association with the passage of right-to-work laws, while union strength holds a negative association with the passage of right-to-work laws. In addition, only presence of a GOP governor holds a negative, statistically significant relationship the introduction of right-to-work bills. Moreover, while the introduction of RTW bills may often be a tool of opposing a non-GOP governorship, I conclude that GOP political strategy serves as the most compelling factor in explaining the resurging passage of right-to-work laws.

description: Carbonaceous chondrite meteorites are known for having high water and organic material contents, including amino acids. Here we address the origin of amino acids in the warm interiors of their parent bodies (planetesimals) within a few million years of their formation, and connect this with the astrochemistry of their natal protostellar disks. We compute both the total amino acid abundance pattern as well as the relative frequencies of amino acids within the CM2 (e.g. Murchison) and CR2 chondrite subclasses based on Strecker reactions within these bodies. We match the relative frequencies to well within an order of magnitude among both CM2 and CR2 meteorites for parent body temperatures $

Optimization of Ambient Ionization Mass Spectrometric Methods to Detect Low Concentrations of Common Agricultural Chemicals, Atrazine and S-Metolachlor
Creators: name: Gadi, Sneha
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2013

description: Methods of ambient ionization mass spectrometry such as paper spray ionization (PSI) and low-temperature plasma ionization (LTPI) allow for real-time analysis of crude samples that require virtually no prior preparation. Although extensive optimization is necessary in order to achieve accurate and reliable results, the ease of analysis coupled with the quality of attained results make ambient ionization techniques such as PSI and LTPI valuable. One important application of such methods is the detection and analysis of common pesticides and herbicides, which are routinely monitored for regulatory and environmental protection purposes. This paper aims to focus especially on one particular herbicide, atrazine, which is of specific interest due to contamination effects and its resilience in environmental systems. PSI of atrazine proved to be effective, with sufficient optimization resulting in reduction of background signal and detection of concentrations in the nanogram range. Deuterated atrazine was used as an internal standard to develop a quantitative method for the measurement of atrazine. The herbicide metolachlor was also analyzed via PSI and showed reliable signal with minimal noise down to the picogram range. LTPI of metolachlor showed similar promising results but was not as successful in low-concentration samples due to high levels of noise and quick sample depletion.

description: Η παρούσα διπλωματική εργασία πραγματεύεται την εξέλιξη της ηλεκτροκίνησης, εστιάζοντας στις πρωτοποριακές εξελίξεις που εισήγαγε το Tesla Roadster. Έχει ως απώτερο σκοπό την ανάδειξη των ηλεκτρικών αυτοκινήτων, την εξέλιξή τους με την πάροδο του χρόνου και τα οφέλη που προσφέρουν στο περιβάλλον. Συγκεκριμένα, γίνεται μία γενικότερη ανάλυση των ηλεκτρικών οχημάτων, δίνοντας έμφαση στη φόρτισή τους, αναλύοντας παράλληλα και την ιστορική εξέλιξη των μπαταριών τους. Ως παράδειγμα χρησιμοποιείται το Tesla Roadster, το οποίο θεωρείται το πρώτο ηλεκτρικό αυτοκίνητο με μπαταρίες ιόντων λιθίου (Li-ion). Παρουσιάζεται μία ιστορική αναδρομή του αυτοκινήτου αυτού, ξεκινώντας από το πρωτότυπο Μοντέλο του 2006, καταλήγοντας στο Μοντέλο 2025, το οποίο αναμένεται να κυκλοφορήσει. Η διπλωματική εργασία εστιάζει κυρίως στον σχεδιασμό του Roadster και τις αλλαγές που υπέστη με τα χρόνια. Γίνεται, ακόμη, μία σύγκριση του αυτοκινήτου αυτού με άλλου είδους οχήματα, παίρνοντας ως παράδειγμα και το Nissan Leaf. Τέλος, εξετάζονται τα περιβαλλοντικά οφέλη της ηλεκτροκίνησης, δείχνοντας, βέβαια, παράλληλα και τα μειονεκτήματά της. Συμπερασματικά, προκύπτει ότι το Tesla Roadster έφερε την επανάσταση στην αυτοκινητοβιομηχανία. Έδειξε στον κόσμο ότι η μετάβαση από τα παραδοσιακά βενζινοκίνητα αυτοκίνητα στα ηλεκτρικά μπορεί να κατορθωθεί. Εστιάζοντας στη βιωσιμότητα και τις ανανεώσιμες πηγές ενέργειας, επισήμανε τη σημασία της μείωσης των εκπομπών διοξειδίου του άνθρακα και της προώθησης της περιβαλλοντικής συνείδησης στον τομέα της αυτοκινητοβιομηχανίας.

description: We obtain exact solutions of the (2+1) dimensional Dirac oscillator in a homogeneous magnetic field within the Anti-Snyder modified uncertainty relation characterized by a momentum cut-off ($p\leq p_{\text{max}}=1/ \sqrtβ$). In ordinary quantum mechanics ($β\to 0$) this system is known to have a single left-right chiral quantum phase transition (QPT). We show that a finite momentum cut-off modifies the spectrum introducing additional quantum phase transitions. It is also shown that the presence of momentum cut-off modifies the degeneracy of the states.

description: Ptomaphaginus caroli spec. nov. (figs 14-15; 26). Type material.— Holotype ♂: Malaysia: Sabah: Crocker Range Park: Gunung Mas (30 km ESE of Kota Kinabalu), 1350 m alt., pitfall with carrion or dung, 31.vii.2000, leg. M. Schilthuizen (BOR). Diagnosis.— Habitus long and narrow, flat (fig. 26). Elytra 1.41 times as long as their combined width (length measured from the caudal tip of the scutellum to the apex of the elytra). Aedeagus (figs 14-15) apically with two short ‘wings’ and a very small, indistinct terminal processus. Description.— Habitus narrow and elongated, relatively flat (fig. 26). Moderately pigmented: mostly chestnut brown; only the legs and the antennal bases and apices lighter yellowish brown. Length 2.7 mm. Antennae slender and relatively long, 1.1 times as long as the width of the head. Articles 6, 9, and 10 slightly wider than long. Male protarsi strongly dilated: the protibia at its largest width (excluding the lateral spines) is 1.2 times broader than the first article of the protarsus. There are no exceptionally long hairs on the ventral side of profemur and protibia. Thorax 1.62 times as wide as long, relatively flat, almost rectilinearly narrowing from caudal to rostral; the caudal corners sharp, narrowly, but distinctly drawn out. The mesosternal carina is strongly developed, its edge somewhat thickened. Elytra long, 1.41 times as long (measured from the caudal tip of the scutellum) as their combined width. Elytral apices distinctly truncate. Aedeagus (figs 14-15) in dorsal view abruptly narrowing towards the apex, and there adorned with two very short lateral ‘wings’. The tip carries a short and obtuse triangular processus. In lateral view, the aedeagus is almost not curved, except for the apical quarter, which is bent ventrad under an obtuse angle. Male genital segment relatively broad, at the apex slightly triangular, 2.5 times as long as wide. Female unknown. Distribution.— Only the holotype is known for this species. At the type locality, it was found syntopically with P. similipes spec. nov. Remarks.— Based on aedeagal shape, P. caroli is closely related to P. bryanti, P. similipes and P. bryantoides. However, it differs from all these by the distinctly elongated habitus (elytral index of 1.41) and the apical ‘wings’ of the aedeagus, which are very short. Etymology.— Named in honour of Carolus Linnaeus. The present paper appears in conjunction with the 250 th anniversary of the publication of Linnaeus’ Systema Naturae on 1 January 1758, which marks the start of zoological nomenclature.

description: We consider a system composed of two identical light quarks ($qq$) and two identical antiquarks ($\bar Q\bar Q$) that can be linked either as two mesons or as a tetraquark, incorporating quantum correlations between identical particles and an effective many-body potential between particles. We perform a 3-D Monte Carlo simulation of the system, considering the configurations allowed to form: i) Only two mesons, ii) Only tetraquark and iii) two mesons and tetraquark . We characterize each case and determine whether it is energetically more favorable to form a tetraquark or two mesons, as a function of the interparticle separation distance which, for a fixed number of particles, can be identified as a particle density. We determine how the two mesons, which dominate the low density regime, mixes with a tetraquark state as the density increases. Properties like the mean square radius and the two-particle correlation function are found to reflect such transition, and we provide a parameterization of the diquark correlation function in the isolated case. We track the dynamical flipping among configurations to determine the recombination probability, exhibiting the importance of the tetraquark state. We analize the four-body potential evolution and show that its linear behavior is preserved, although the slope can reflect the presence of a mixed state. Results are shown for several light-quarks to heavy-antiquarks mass ratios whenever they are found to be relevant.

Year: 2019

description: This paper studies the empirical validity of a novel parameterization of a correlation matrixcalled the Generalized Fisher Z-Transformation. This parameterization has a number of desirablecharacteristics, including increasing Gaussian properties and ensuring a positive definitecorrelation matrix. The empirical validity is tested through including it as a signal in DCCGARCH variance forecasting models and comparing its additive forecasting value to traditionalDCC-GARCH models and DCC-GARCH models with realized measures of volatility as a signal.The accuracy of the forecasted conditional variances are tested using in-sample and out-ofsample estimated log-likelihood. Additionally, the forecasted variances are also comparedthrough a global mean-variance portfolio optimization process, calculating weights from theforecasted conditional covariance. This research found that including the GFT as a signalimproves on traditional DCC-GARCH models and performs similarly to DCC models augmentedwith realized volatility during in-sample evaluation. Similarly, in out-of-sample evaluation, theGFT models is dominant to the DCC-GARCH model. However, it performs significantly worsethan the model augmented with realized volatility.

Grav. 11, 2499-2506 (1994)]. It is found that if such a wall exists within our observable universe, it would be absurdly thick, or else have a magnetic field in its core which is much stronger than observed intergalactic fields. We conclude that it is highly improbable that any such wall is physically realized.

description: The search strategy for the memory trace and its semantics is exemplified for the case of olfactory learning in the honeybee brain. The logic of associative learning is used to guide the experimental approach into the brain by identifying the anatomical and functional convergence sites of the conditioned stimulus and unconditioned stimulus pathways. Two of the several convergence sites are examined in detail, the antennal lobe as the first-order sensory coding area, and the input region of the mushroom body as a higher order integration center. The memory trace is identified as the pattern of associative changes on the level of synapses. The synapses are recruited, drop out, and change the transmission properties for both specifically associated stimulus and the non-associated stimulus. Several rules extracted from behavioral studies are found to be mirrored in the patterns of synaptic change. The strengths and the weaknesses of the honeybee as a model for the search for the memory trace are addressed in a comparison with Drosophila. The question is discussed whether the memory trace exists as a hidden pattern of change if it is not retrieved and whether an external reading of the content of the memory trace may ever be possible. Doubts are raised on the basis that the retrieval circuits are part of the memory trace. The concept of a memory trace existing beyond retrieval is defended by referring to two well-documented processes also in the honeybee, memory consolidation during sleep, and transfer of memory across brain areas.

description: Despite recent treatment advances, non-small cell lung cancer (NSCLC) remains one of the leading causes of cancer-related deaths worldwide, and therefore it necessitates the exploration of new therapy options. One commonly shared feature of malignant cells is their ability to hijack metabolic pathways to confer survival or proliferation. In this study, we highlight the importance of the polyol pathway (PP) in NSCLC metabolism. This pathway is solely responsible for metabolizing glucose to fructose based on the enzymatic activity of aldose reductase (AKR1B1) and sorbitol dehydrogenase (SORD). Via genetic and pharmacological manipulations, we reveal that PP activity is indispensable for NSCLC growth and survival in vitro and in murine xenograft models. Mechanistically, PP deficiency provokes multifactorial deficits, ranging from energetic breakdown and DNA damage, that ultimately trigger the induction of apoptosis. At the molecular level, this process is driven by pro-apoptotic JNK signaling and concomitant upregulation of the transcription factors c-Jun and ATF3. Moreover, we show that fructose, the PP end-product, as well as other non-glycolytic hexoses confer survival to cancer cells and resistance against chemotherapy via sustained NF-κB activity as well as an oxidative switch in metabolism. Given the detrimental consequence of PP gene targeting on growth and survival, we propose PP pathway interference as a viable therapeutic approach against NSCLC.

description: Graphite intercalation compounds (GICs) have a variety of functions due to their rich material variations, and thus,innovative methods for their synthesis are desired for practical applications. We have discovered that Na has a catalytic property that dramatically accelerates the formation of GICs. We demonstrate that LiC6n (n = 1, 2), KC8, KC12n (n = 2, 3, 4), and NaCx are synthesized simply by mixing alkali metals and graphite powder with Na at room temperature (~25 °C), and AEC6 (AE = Ca, Sr, Ba) are synthesized by heating Na-added reagents at 250 °C only for a few hours. The NaCx, formed by the mixing of C and Na, is understood to act as a reaction intermediate for a catalyst, thereby accelerating the formation of GICs by lowering the activation energy of intercalation. The Na-catalyzed method, which enables the rapid and mass synthesis of homogeneous GIC samples in a significantly simpler manner than conventional methods, is anticipated to stimulate research and development for GIC applications.

Would the Trees Dim the Lights? Adopting the Intentional Stance for More-Than-Human Participatory Design

description: The 2019/20 Black Summer bushfires in Australia demonstrated the brutal and disastrous consequences of changing the technological world without considering linkages with the biophysical, ecological or human worlds. An emerging more-than-human design philosophy encourages designers to consider such interrelations between humans and non-human entities. Yet, the design research community has focused on situated or embodied experiences for designers, rather than developing processes to legitimate the perspectives of non-human entities through participatory design. This paper explores how adopting the `intentional stance', a concept from philosophy, might provide a heuristic for more-than-human participatory design. Through experimentation with the intentional stance in the context of smart lighting systems, the paper demonstrates that the approach has potential for non-human entities from the ecological world, but less so for the biophysical world. The paper concludes by encouraging critique and evolution of the intentional stance, and of other approaches, to legitimate the perspectives of non-human entities in everyday design.

description: Der Beitrag des Luftverkehrs zum anthropogenen Klimawandel wird auf etwa 4 % geschätzt. In diesem Zusammenhang werden alternative Kraftstoffe als eine wichtige Maßnahme zur Verringerung der Treibhausgasemissionen im Luftverkehrssystem und damit zur Verringerung des Beitrags des gewerblichen Luftverkehrs zum anthropogenen Klimawandel angesehen. Dennoch liegt der Nutzungsanteil alternativer Kraftstoffe bisher unter 1 %. Ziel dieses Papiers ist es daher, eine breite Auswahl von Flugkraftstoffoptionen auf ihr Treibhausgasminderungspotenzial hin zu analysieren und Szenarien für ihre mögliche zukünftige Entwicklung abzuleiten. Bei den untersuchten Kraftstoffoptionen handelt es sich um gemischtes synthetisches Kerosin und reines synthetisches Kerosin, drei Alkohole (Methanol, Ethanol und Butanol) und drei Gase (Methan, Ammoniak und Wasserstoff). Es wurden allgemeine sozioökonomische Voraussetzungen und Anforderungen innerhalb des Luftverkehrssystems ermittelt. Die Entwicklung des Energiebedarfs im Luftverkehr, der Ausbau der Produktionskapazitäten und die Bereitschaft, die Kosten der Energiewende zu tragen, scheinen die wichtigsten Hebel für einen erfolgreichen Übergang zu erneuerbaren Energien zu sein.
description: The air transport sector’s contribution to anthropogenic climate forcing is estimated at around 4 %. In this respect, alternative fuels are considered as a key measure to reduce greenhouse gas emissions within the air transport system and thus to reduce the contribution of commercial aviation to anthropogenic climate change. Nevertheless, so far the usage-shares of alternative fuels are below 1 %. Thus, the goal of this paper is to analyse a broad selection of aviation fuel options for their greenhouse gas reduction potential based and to derive scenarios for their potential future development. The fuel options studied are blended synthetic kerosene and neat synthetic kerosene fuels, three alcohols (methanol, ethanol and butanol) and three gases (methane, ammonia and hydrogen). General socio-economic preconditions and requirements within the air transport system were identified. Key Levers for a successful transition towards renewably sourced energies appear to be the development of aviation's energy demand, the ramp-up of production capacities and the willingness to cover the cost of the energy transition.
The Effect of Oral Health on Overall Self-Perceived Health in Individuals with Recent and Long-Term Human Immunodeficiency Virus (HIV) Diagnosis

description: Objective: Dental care is among the top unmet needs for people living with HIV (PLWH). The effect of oral health on overall health has been understudied in PLWH. This longitudinal study sought to determine the impact of comprehensive dental intervention on quality of life using a validated short form -8 (SF-8) in newly vs previously diagnosed PLWH.
Methods: 84 subjects were divided into 3 groups: newly diagnosed (≤1 year since HIV diagnosis/no regular dental care), previously diagnosed (>1 year since HIV diagnosis/ no regular dental care) and historical (>1 year since HIV diagnosis/ receiving regular dental care). Dental prophylaxis/ debridement, oral hygiene instruction, and interviews were conducted that included the SF-8, factors affecting oral health, HIV status and demographics at 6 month intervals for 24 mo. Comprehensive dental care was provided.
Results: The majority of subjects were male (76.19%) and African-American (64.28%), and the mean age was 45. Their mean income was less than $851/month and most had at least a high school education. At baseline, their mean CD4 and HIV viral load were 512.15 cells/ul and 560.68 copies/ ml, respectively. The mean SF-8 percentage scores at baseline for the newly, previously and historically diagnosed subjects were 75.2%, 74.9%, and 73.4% respectively. SF-8 scores after 12 months for the three groups were 81.8% 78.7%, and 76.7% respectively with the mean raw SF- higher score correlated to better self-perceived health. Continued increase in composite raw scores were detected in the previously diagnosed and historical groups at 24- month, scores were 82.7%, and 78.3% respectively.
Conclusion: Among the three groups, those in the previously diagnosed group showed the greatest improvement in overall self-perceived health. This suggests that the oral intervention was most effective in the previously diagnosed. Overall self-perceived wellness in those with long-term HIV diagnosis improved with comprehensive dental care.

description: Skynet is an international network of over two dozen optical robotic telescopes operated out of the University of North Carolina at Chapel Hill. In response to recently acquired privileges of the 20-meter diameter radio telescope located at Green Bank Observatory, Skynet has developed a new radio image processing software which hosts a number of advantages over traditional radio image processing techniques. The most noteworthy of these advantages include the use of weighted modeling over weighted averaging--the former being a procedure that blurs astrophysical structure as high as 40%--and the use of local, rather than global, modeling to differentiate astrophysical signal from various forms of radio contaminants. Our algorithm also makes frequent use of robust Chauvenet rejection (RCR), a new outlier rejection algorithm. RCR is capable of resolving both accurate and precise mu and sigma values for distributions containing as high as 85% contaminated data, making it particularly advantageous for removing radio contamination. Together, these techniques produce allow our image processing software to produce contaminant-cleaned and photometrically viable images for professional and amateur use.

description: We investigate the influence of a quantized photon field on thermoelectric transport of electrons through a quantum wire embedded in a photon cavity. The quantum wire is connected to two electron reservoirs at different temperatures leading to a generation of a thermoelectric current. The transient thermoelectric current strongly depends on the photon energy and the number of photons initially in the cavity. Two different regimes are studied, off-resonant and resonant polarized fields, with photon energy smaller than, or equal to the energy spacing between some of the lowest states in the quantum wire. We observe that the current is inverted for the off-resonant photon field due to participation of photon replica states in the transport. A reduction in the current is recorded for the resonant photon field, a direct consequence of the Rabi-splitting.

Οι χάρτες δημιουργήθηκαν με δεδομένα που πάρθηκαν από τη Eurostat και στη συνέχεια αναλύθηκαν μέσω συστήματος γεωγραφικών πληροφοριών (ΓΣΠ), και πιο συγκεκριμένα το ArcGIS Pro. Σε πρώτη φάση, η έρευνα αναφέρεται στο πως έχει επηρεάσει η κλιματική αλλαγή τα οικοσυστήματα, τους πολίτες αλλά και τις κυβερνήσεις της Ευρώπης και στη συνέχεια δίνεται έμφαση στις πιθανές λύσεις, ώστε να εξομαλυνθούν οι επιπτώσεις της. Επιπλέον η εργασία αναφέρεται στη σημαντικότητα που λαμβάνει χώρα ο άνθρωπος και για την πρόκληση αυτού του φαινομένου αλλά και για την μείωση των ακραίων φαινομένων που προκαλεί, αφού αναλύονται οι επιπτώσεις του. Επίσης γίνεται εμφανές ότι ορισμένες ομάδες ανθρώπων είναι περισσότερο ευάλωτες στα αποτελέσματα του φαινομένου και χρήζουν ιδιαίτερης προστασίας.

description: In a recent paper, one of us studied spherically symmetric, asymptotically flat solutions of Shape Dynamics, finding that the spatial metric has characteristics of a wormhole - two asymptotically flat ends and a minimal-area sphere, or `throat', in between. In this paper we investigate whether that solution can emerge as a result of gravitational collapse of matter. With this goal, we study the simplest kind of spherically-symmetric matter: an infinitely-thin shell of dust. Our system can be understood as a model of a star accreting a thin layer of matter. We solve the dynamics of the shell exactly and find that, indeed, as it collapses, the shell leaves in its wake the wormhole metric. In the maximal-slicing time we use for asymptotically flat solutions, the shell only approaches the throat asymptotically and does not cross it in a finite amount of time (as measured by a clock `at infinity'). This leaves open the possibility that a more realistic cosmological solution of Shape Dynamics might see this crossing happening in a finite amount of time (as measured by the change of relational/shape degrees of freedom).

description: Our goal in this research is to develop and integrate three-dimensional collision-avoidance
and navigation with physical agents, such as micro-air vehicles (MAVs). We build
on prior techniques based on reciprocal velocity obstacles (RVOs) for collision-free
navigation and use the ArduCopter quad-rotor helicopters, designed by 3D Robotics, as the
physical agents. MAVLink, a communications protocol for micro-air vehicles, is used with the
Mission Planner ground-station software providing hardware- and software-in-the-loop
capabilities to interface between the quadcopters and the RVO software. We also extend
RVO-based 3D collision algorithms to take into account kinematic and dynamic constraints,
including bounds on the turn radius, maximum altitude, maximum velocity, etc., and
highlight the results using our simulator.

Global structure and geodesics for Koenigs superintegrable systems

description: Starting from the framework defined by Matveev and Shevchishin we derive the local and the global structure for the four types of super-integrable Koenigs metrics. These dynamical systems are always defined on non-compact manifolds, namely $\,{\mb R}^2\,$ and $\,{\mb H}^2$. The study of their geodesic flows is made easier using their linear and quadratic integrals. Using Carter (or minimal) quantization we show that the formal superintegrability is preserved at the quantum level and in two cases, for which all of the geodesics are closed, it is even possible to compute the discrete spectrum of the quantum hamiltonian.

Systematic Analysis of Yeast F-box Proteins Reveals a New Role of Ubiquitination in Polarity Establishment

description: DNA is wrapped around a histone protein bundle, and these histone proteins can undergo post-translational modifications which then participate in signaling pathways to regulate important cellular functions. One such histone modification is methylation, where lysine can be mono, di, or tri-methylated. Reader proteins bind to methyl lysine and serve as docking sites for additional proteins that alter gene expression or chromatin structure. Dysregulation of histone methylation has been associated with certain types of cancer; therefore, it is necessary to understand the driving forces for binding of methylated lysine by these reader proteins to aid the development of reader protein probes or inhibitors with the desired specificity. In this project, the cation- interaction between trimethylated lysine 9 (Kme3) of H3 and the Drosophila reader protein, HP1 chromodomain, is investigated. The binding site of HP1 is comprised of three aromatic amino acids, two tyrosine residues and a tryptophan. To better understand the contribution of tryptophan in this cation-π binding event, an unnatural tryptophan analog is synthesized with 1 fluorine atom, which is highly electron-withdrawing, attached to the outer aromatic rung. Once synthesized, these unnatural analogs will then be inserted into the HP1 binding site. Comparative binding studies between the wild type and mutant protein with the Kme3 peptide will provide a better understanding of the cation-π  mechanism. If Kme3 binds less tightly to the mutated binding pockets, it will indicate the importance of the tryptophan-π  contribution to binding.
MENA Higher Education Privatization's Unintended Effect on MENA Economies and the MENA Refugee Crisis
Creators: name: Hogenkamp, Daniel
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2016

description: This paper analyzes the Middle Eastern and North African (MENA) economic
landscape, in particular the MENA highly-educated labor market, in the years preceding
the MENA and European Refugee Crises to discern what public policies and migration
push factors encouraged MENA refugees to re-seek asylum in Europe. I use econometric
analysis to analyze World Bank Development Indicators, Middle Eastern University
Data, Anabin University Data, World Bank Migration Data, and World Bank Remittance
Data.
I find that MENA higher education privatization significantly expanded the
number of MENA universities, lowered the quality of MENA higher education, created
far more college graduates than jobs requiring higher education, helped create the MENA
labor market skills mismatch, and furthered regional unemployment— especially for
youth and college graduates. I find that high MENA unemployment has encouraged
displaced MENA refugees, especially those with college degrees, to seek asylum outside
of the MENA region and in Europe. The ramifications of my findings suggest that 1)
MENA refugees re-seek asylum in Europe for formal labor opportunities, 2) MENA
refugees disproportionately possess college degrees, and 3) that the quality of MENA
refugees’ college degrees may often fall below Western standards.

description: Modern networks are becoming increasingly interdependent. As a prominent example, the smart grid is an electrical grid controlled through a communications network, which in turn is powered by the electrical grid. Such interdependencies create new vulnerabilities and make these networks more susceptible to failures. In particular, failures can easily spread across these networks due to their interdependencies, possibly causing cascade effects with a devastating impact on their functionalities. In this paper we focus on the interdependence between the power grid and the communications network, and propose a novel realistic model, HINT (Heterogeneous Interdependent NeTworks), to study the evolution of cascading failures. Our model takes into account the heterogeneity of such networks as well as their complex interdependencies. We compare HINT with previously proposed models both on synthetic and real network topologies. Experimental results show that existing models oversimplify the failure evolution and network functionality requirements, resulting in severe underestimations of the cascading failures.

description: This paper deals with left non-degenerate set-theoretic solutions to the Yang-Baxter equation (=LND solutions), a vast class of algebraic structures encompassing groups, racks, and cycle sets. To each such solution is associated a shelf (i.e., a self-distributive structure) which captures its major properties. We consider two (co)homology theories for LND solutions, one of which was previously known, in a reduced form, for biracks only. An explicit isomorphism between these theories is described. For groups and racks we recover their classical (co)homology, whereas for cycle sets we get new constructions. For a certain type of LND solutions, including quandles and non-degenerate cycle sets, the (co)homologies split into the degenerate and the normalized parts. We express 2-cocycles of our theories in terms of group cohomology, and, in the case of cycle sets, establish connexions with extensions. This leads to a construction of cycle sets with interesting properties.
