title: A Quantum Deformation of the Second Weyl Algebra: Its derivations and poisson derivations
Creators: name: Oppong, Isaac
Publisher: name: University of Kent
Year: 2022

description: Since the introduction of quantum algebras in the 1980's, many have introduced quantum deformations of the Weyl algebras. Two such examples are the quantum Weyl algebras and the Generalized Weyl algebras. In this thesis, we use a different approach to find deformations of (a quadratic extension of) the second Weyl algebra A_2(C), and compare some properties of these deformations to those of A_2(C). Let n be a nilpotent Lie algebra, U(n) the enveloping algebra of n and Q a primitive ideal of U(n). Dixmier [12] proved that the factor algebra U(n)/Q is isomorphic to an n^{th} Weyl algebra A_n(C), where n ∈ N_{≥1}. This isomorphism gives a route to construct potential deformations for any Weyl algebra. Let g = g^ − ⊕ h ⊕ g^ + represent a simple Lie algebra. Now, Dixmier's result holds for n = g^+. Since U_ q^+ (g) is a q-deformation of U(g^+), it is natural to consider U_q^+(g)/P, where P is a primitive ideal of U_q^+ (g), as a potential deformation of the Weyl algebras. This thesis focuses on the case where g = G_2. We find a family of primitive ideals (P_{α,β})_{(α,β)∈C^2\(0,0)} of U _ q^ (G_2) whose corresponding quotients A_{α,β} := U_q^+ (G_2)/P_{α,β} are simple noetherian domains of Gelfand-Kirillov dimension 4. In view of Dixmier's result, we consider A_{α,β} as a q-deformation of (a quadratic extension of) A_2(C). The derivations of the Weyl algebras are all known to be inner derivations [5]. Motivated by this, we also study the derivations of A_{α,β} and compare them to those of the Weyl algebras. The final part of the thesis studies a Poisson derivation of a semiclassical limit \mathcal{A}_{α,β} of A_{α,β}. Interestingly, the Poisson derivations of \mathcal{A}_{α,β} and the derivations of A_{α,β} are congruent.

description: Although speech and gesture recognition has been studied extensively, all the successful attempts of combining them in the unified framework were semantically motivated, e.g., keyword-gesture cooccurrence. Such formulations inherited the complexity of natural language processing. This paper presents a Bayesian formulation that uses a phenomenon of gesture and speech articulation for improving accuracy of automatic recognition of continuous coverbal gestures. The prosodic features from the speech signal were coanalyzed with the visual signal to learn the prior probability of co-occurrence of the prominent spoken segments with the particular kinematical phases of gestures. It was found that the above co-analysis helps in detecting and disambiguating visually small gestures, which subsequently improves the rate of continuous gesture recognition. The efficacy of the proposed approach was demonstrated on a large database collected from the weather channel broadcast. This formulation opens new avenues for bottom-up frameworks of multimodal integration.

description: Transport properties of permalloy doped with V, Co, Pt, and Au are explored via ab-initio calculations. The Kubo-Bastin formula is evaluated within the fully relativistic Korringa-Kohn-Rostoker Green function formalism. Finite temperature effects are treated by means of the alloy analogy model. It is shown that the fact that the host is disordered and not crystalline has a profound effect on how the conductivities characterizing the anomalous Hall effect and the spin Hall effect depend on the dopant concentration. Several relationships between quantities characterizing charge and spin transport are highlighted. The decrease of the longitudinal charge conductivity with increasing doping depends on the dopant type, following the sequence Co-Au-Pt-V. The dependence of the anomalous Hall and spin Hall conductivities on the dopant concentration is found to be non-monotonic. Introducing a finite temperature changes the overall trends significantly. The theoretical results are compared with available experimental data.

description: One of the objectives of the macroprudential policy instrument is to reduce the procyclicality of bank credit growth. This study aims to analyze the Bank Indonesia macroprudential policy in controlling property loans. The research variables consist of independent variables, namely loan to value (LTV) as dummy variables, consumption loan interest rates, GDP and LTV as interaction variables with consumer loans and the dependent variable, namely property loans. The research method uses panel data regression analysis. The data used in this study are secondary data for the period 2009 - 2018. The results show that the fixed effect model is the right model for analyzing whether macroprudential policy instruments (LTV) are able to control property credit.
Transition to plastic motion as a critical phenomenon and anomalous interface layer of a 2D driven vortex lattice

description: The dynamic transition between the ordered flow and the plastic flow is studied for a two-dimensional driven vortex lattice, in the presence of sharp and dense pinning centers, from numerical simulations. For this system, which does not show smectic ordering, the lattice exhibits a first order transition from a crystal to a liquid, shortly followed by the dynamical transition to the plastic flow. The resistivity provides a critical order parameter for the latter, and critical exponents are determined in analogy with a percolation transition. At the boundary between a pinned region and an unpinned one, an anomalous layer is observed, where the vortices are more strongly pinned than in the bulk.

description: Recently, iron-chalcogenide superconductors have emerged as a new and promising platform for studying and manipulating Majorana zero mode (MZM). By combining topological band structure and superconductivity in a multiband material, they provide significant advantages such as higher superconducting transition temperature (Tc) and isolated Majorana mode. However, iron-chalcogenide superconductors, especially Fe(Te,Se), suffer from strong inhomogeneity which may hamper their practical application. On the other hand, some iron-pnictide (Fe-As) superconductors, such as LiFeAs, have been demonstrated to have a similar topological band structure, yet no MZM has been observed in its vortex cores, raising a question of universality of MZM presence in iron-based superconductors. In this work, by using high-resolution angle-resolved photoemission spectroscopy and scanning tunneling microscopy/spectroscopy, we identify the first Fe-As superconductor CaKFe4As4 (Tc = 35 K) which has both the superconducting Dirac surface states and the MZMs inside its vortex cores. The topological band inversion is largely due to the down-shift of the pz band caused by the bilayer band folding in this material. More strikingly, the energies and spatial line profiles of MZM and multiple quantized Caroli-de Gennes-Matricon bound states observed inside the topological vortex can be accurately reproduced by a simple theoretical model derived from a surface Dirac cone, firmly establishing Majorana nature of the zero mode.

description: Organisms often use cyclic changes in the concentrations of chemicals species to precisely time biological functions. Underlying these biochemical clocks are chemical reactions and transport processes, which are inherently stochastic. Understanding the physical basis for robust biochemical oscillations in the presence of fluctuations has thus emerged as an important problem. In a previous paper [C. del Junco and S. Vaikuntanathan, Phys. Rev. E 101, 012410 (2020)], we explored this question using the non-equilibrium statistical mechanics of single-ring Markov state models of biochemical networks that support oscillations. Our finding was that they can exploit non-equilibrium driving to robustly maintain the period and coherence of oscillations in the presence of randomness in the rates. Here, we extend our work to Markov state models consisting of a large cycle decorated with multiple small cycles. These additional cycles are intended to represent alternate pathways that the oscillator may take as it fluctuates about its average path. Combining a mapping to single-cycle networks based on first passage time distributions with our previously developed theory, we are able to make analytical predictions for the period and coherence of oscillations in these networks. One implication of our predictions is that a high energy budget can make different network topologies and arrangements of rates degenerate as far as the period and coherence of oscillations is concerned. Excellent agreement between analytical and numerical results confirms that this is the case. Our results suggest that biochemical oscillators can be more robust to fluctuations in the path of the oscillator when they have a high energy budget.

description: This article discusses the external dynamics that resulted in the proliferation of arms into Kenya in general and Northern Kenya in specific. The paper has two major arguments. First, during the cold war, there was an arms race in the region because of its strategic position. This resulted in the two superpowers, USA and USSR, to arm specific countries that were considered to be friendly to them. Second, the paper argues that beginning in the early '70s into the '80s and early 90s, a number of countries in the Horn of Africa experienced turmoil or civil strife. Political instability in Somalia made Kenyan Somalis able to obtain guns by volunteering to join the fight for the Ogaden in Ethiopia and then slipped back into Kenya. The current study found that the conflict in North Eastern Kenya is caused by scarcity of resources, economic and political marginalization, active resistance by pastoralist communities to assimilation, resource depletion, and demographic changes, and the growing availability of small arms and light weapons. Livestock has become the triggers and the medium for sustaining conflicts through cattle raiding for wealth accumulation and also for dowry payments. Modern technology has also become a clear instrument of conflict escalation. Pastoral communities in northern Kenya provide an excellent market for firearms. The study concludes that political instability in Somalia made Kenyan Somalis able to obtain guns by volunteering to join the fight for the Ogaden in Ethiopia and then slipped back into Kenya. The rivalry between Ethiopia and Eritrea led to an arms race between the two nations, where each country is involved in the massive acquisition of arms.

description: We present a theory for the steady-state dynamics of a two-dimensional system of spherically symmetric active Brownian particles. The derivation of the theory consists of two steps. First, we integrate out the self-propulsions and obtain a many-particle evolution equation for the probability distribution of the particles' positions. Second, we use projection operator technique and a mode-coupling-like factorization approximation to derive an equation of motion for the density correlation function. The nonequilibrium character of the active system manifests itself through the presence of a steady-state correlation function that quantifies spatial correlations of microscopic steady-state currents of the particles. This function determines the dependence of the short-time dynamics on the activity. It also enters into the expression for the memory matrix and thus influences the long-time glassy dynamics.

description: We show how the motion through the extra dimensions of a gas of branes and antibranes can, under certain circumstances, produce an era of inflation as seen by observers trapped on a 3-brane, with the inflaton being the inter-brane separation. Although most of our discussion refers to arbitrary p-branes, when we need to be specific we assume that they are D-branes of Type II or Type I string theory. For realistic brane couplings, such as those arising in string theory, the inter-brane potentials are too steep to inflate the universe for acceptably long times. However, for special regions of the parameter space of brane-antibrane positions the brane motion is slow enough for there to be sufficient inflation. Inflation would be more generic in models where the inter-brane interactions are much weaker. The spectrum of primordial density fluctuations predicted has index n slightly less than 1, and an acceptable amplitude, provided that the extra dimensions have linear size 1/r ~ 10^{12} GeV. Reheating occurs as in hybrid inflation, with the tachyonic instability of the brane-antibrane system taking over for small separations. The tachyon field can induce a cascade mechanism within which higher-dimension branes annihilate into lower-dimension ones. We argue that such a cascade naturally stops with the production of 3-branes in 10-dimensional string theory.

description: Investments in agricultural land have recently gained particular public attention both in the international and national context. In Germany, the recent increase in sale and rental prices for agricultural land has often been linked to the activities of non-agricultural investors. The aim of this study is to take stock of these activities and to explore the relevance of nonagricultural and supra-regional investors. Further, it is aimed at investigating the impact of such activities on the land market, agricultural structures and regional development. Four regional case studies are carried out, three of them in the New Länder (former GDR). In each case study region, structured interviews were conducted with about ten farm managers and ten regional experts. Results show that the group of ‘non-agricultural investors’ is very heterogeneous and cannot be delimited by clear indicators. Thus, the core question about the relevance of their activities can only be answered with respect to the type of investor. Judgements as regards their impact are highly dependent on the selection of regional case studies, the type of interviewees and their respective interests. Investitionen in landwirtschaftliche Flächen sind in den letzten Jahren sowohl international als auch in Deutschland vermehrt in der öffentlichen Diskussion. Dabei wurde der jüngst zu verzeichnende Anstieg von Kauf- und Pachtpreisen in Deutschland vielfach mit Aktivitäten nichtlandwirtschaftlicher Investoren in Zusammenhang gebracht. Ziel dieser Studie ist eine Bestandsaufnahme solcher Aktivitäten. Untersucht werden die Relevanz und die Wirkungen der Aktivitäten nichtlandwirtschaftlicher und überregional aktiver Investoren auf den Bodenmarkt, die Agrarstruktur und die regionale Entwicklung. Im Mittelpunkt der Studie stehen vier regionale Fallstudien, davon drei in den neuen Bundesländern. In jeder Fallregion wurden strukturierte Interviews mit rund zehn Landwirten und zehn regionalen Experten geführt. Im Ergebnis zeigt sich die Gruppe der „nichtlandwirtschaftlichen Investoren“ als sehr heterogen und nicht klar abgrenzbar. Die Kernfrage nach der Relevanz dieser Investoren lässt sich daher nur in Abhängigkeit davon beantworten, welche Art von Investoren gemeint ist. Die Bewertung der Wirkungen fällt je nach Fallstudie und Interviewpartner bzw. dessen Interessen sehr unterschiedlich aus.

description: A new extension of the attractive Hubbard model is constructed to study the critical behavior near a finite temperature superconducting phase transition in two dimensions using the recently developed meron-cluster algorithm. Unlike previous calculations in the attractive Hubbard model which were limited to small lattices, the new algorithm is used to study the critical behavior on lattices as large as $128\times 128$. These precise results for the first time show that a fermionic system can undergo a finite temperature phase transition whose critical behavior is well described by the predictions of Kosterlitz and Thouless almost three decades ago. In particular it is confirmed that the spatial winding number susceptibility obeys the well known predictions of finite size scaling for $T

description: Although determinants of agricultural land prices have received considerable attention in the literature, little is known about price formation on structured markets such as land auctions. This paper aims to empirically test theoretical predictions regarding price formation in land market auctions. The analysis is conducted for the case of Saxony-Anhalt, Germany, where state-owned land constitutes a significant share of the agricultural land market. The utilised data consists of public auction data provided by the Landgesellschaft Sachsen-Anhalt (i.e. the rural development agency in Saxony-Anhalt), and covers approximately 700 calls for bids from 2003 to 2010, supplemented with regional and structural data. Spatial correlation of land prices is considered by applying a spatial econometrics approach. Our analysis shows that apart from land characteristics, the number of bidders and the share of non-agricultural investors have an impact on the land price. Der landwirtschaftliche Bodenmarkt ist Gegenstand zahlreicher empirischer Analysen, und es ist weitgehend unstrittig, welches die hauptsächlichen Preisdeterminanten sind. Allerdings ist wenig über die Preisbildung in strukturierten Märkten bekannt, beispielsweise Auktionen mit öffentlichen Ausschreibungen. Ziel dieser Studie ist es, auf Basis der Auktionspreistheorie Hypothesen über die Wirkung auktionsspezifischer Preisdeterminanten herzuleiten und empirisch zu prüfen. Die Analyse wird exemplarisch für Sachsen-Anhalt durchgeführt, da in diesem Bundesland die Landgesellschaft Sachsen-Anhalt im Rahmen des Privatisierungsprozesses der ehemals volkseigenen Flächen als institutioneller Anbieter auf dem Bodenmarkt agiert und öffentlich ausschreibt. Der verwendete Datensatz umfasst circa 700 Ausschreibungen im Zeitraum von 2003 bis 2010, die mit strukturellen Daten aus der Regionalstatistik angereichert werden. Unter Berücksichtigung von räumlicher Korrelation der Preise mittels räumlich-ökonometrischer Methoden kann gezeigt werden, dass zum einen die Eigenschaften des Flächenloses, wie zum Beispiel die Bodenqualität, und zum anderen auktionsspezifische Variablen, wie die Anzahl der Gebote sowie der Anteil nicht-landwirtschaftlicher Bieter, den Preis signifikant beeinflussen.

description: Motivated by recent experiments and density functional theory calculations on choloalite PbCuTe$_2$O$_6$, which possesses a Cu-based three-dimensional hyperkagome lattice, we propose and study a $J_1$-$J_2$-$J_3$ antiferromagnetic Heisenberg model on a hyperkagome lattice. In the classical limit, possible ground states are analyzed by two triangle rules, i.e., the "hyperkagome triangle rule" and the "isolated triangle rule," and classical Monte Carlo simulations are exploited to identify possible classical magnetic ordering and explore the phase diagram. In the quantum regime, Schwinger boson theory is applied to study possible quantum spin liquid states and long-range magnetically ordered states on an equal footing. These quantum states with bosonic partons are classified and analyzed by using projective symmetry groups (PSGs). It is found that there are only four types of algebraic PSGs allowed by the space group $P4_{1}32$ on a hyperkagome lattice. Moreover, there are only two types of PSGs that are compatible with the $J_1$-$J_2$-$J_3$ Heisenberg model. These two types of $Z_2$ bosonic states are distinguished by the gauge-invariant flux on the elementary ten-site loops on the hyperkagome network, called zero-flux state and $π$-flux state respectively. Both the zero-flux state and the $π$-flux state are able to give rise to quantum spin liquid states as well as magnetically ordered states, and the zero-flux states and the $π$-flux states can be distinguished by the lower and upper edges of the spectral function $S(\bm{q},ω)$, which can be measured by inelastic neutron scattering experiments.

description: This paper analyses how different types of buyers affect the farmland price. We specify a flexible hedonic land pricing model that allows for non-uniform valuation of land characteristics among buyers. Data on 579 land sale contracts from five districts of the Czech Republic from 2008-2010 are utilised in the study. The results provide strong evidence of buyerspecific valuation of land’s productive and site characteristics as well as systemic differences in land market conditions among groups of buyers, both of which affect the land price. Non-agricultural buyers are observed to significantly overbid agricultural buyers on land location and site characteristics rather than productive qualities. Among agricultural buyers, joint stock companies and cooperatives enjoy major land price discounts, while individual private farms and limited liability companies face land market access constraints that are surmountable only through paying high price premiums. These observations have important implications for future land ownership structure and land use efficiency. Der Aufsatz analysiert, wie unterschiedliche Typen von Käufern den Bodenpreis beeinflussen. Wir spezifizieren ein flexibles hedonisches Bodenpreis-Modell, das Unterschiede in der Bewertung von Bodeneigenschaften durch verschiedene Käufer erfasst. Daten aus 579 Verträgen zu Bodenkäufern aus fünf tschechischen Landkreisen der Jahre 2008 bis 2011 liegen der Analyse zugrunde. Die Ergebnisse liefern eindeutige Belege, dass sowohl käuferspezifische Bewertungen der Bodenproduktivität und Standorteigenschaften als auch systematische Unterschiede in den Marktbedingungen zwischen den Gruppen von Käufern den Preis beeinflussen. Nichtlandwirtschaftliche Käufer bieten signifikant höhere Preise als Käufer mit einem landwirtschaftlichen Hintergrund, dabei achten sie weniger auf die Bodenqualität, sondern schätzen mehr die Lage und andere Standortcharakteristika. Bei den landwirtschaftlichen Käufern werden Aktiengesellschaften und Genossenschaften oft große Preisnachlässe gewährt. Privatlandwirte und GmbHs sehen sich dagegen Beschränkungen im Zugang zum Bodenmarkt ausgesetzt, die nur durch Zahlung von signifikanten Preisprämien überwindbar sind. Diese Ergebnisse haben wichtige Implikationen für die zukünftige Bodeneigentumsstruktur und Effizienz der Bodennutzung.

Large Electric Dipole Moments of Heavy Leptons

description: In many models of CP violation, the electric dipole moments (EDMs) of leptons scale as the cube of the lepton mass. In these models, the EDM of a 100 GeV heavy lepton would be a billion times greater than that of the muon, and could be as large as a 0.01 e-fermi. In other models, in which the heavy leptons have different properties from the lighter generations, a similarly large EDM can be obtained. A large EDM could dominate the electromagnetic properties of heavy leptons. The angular distribution and production cross-section of both charged and neutral heavy leptons with large dipole moments is calculated and discussed. The interesting possibility that a heavy neutrino with a large EDM could leave an ionization track in a drift chamber is investigated.

description: One approach to quantifying biological diversity consists of characterizing the statistical distribution of specific properties of a taxonomic group or habitat. Microorganisms living in fluid environments, and for whom motility is key, exploit propulsion resulting from a rich variety of shapes, forms, and swimming strategies. Here, we explore the variability of swimming speed for unicellular eukaryotes based on published data. The data naturally partitions into that from flagellates (with a small number of flagella) and from ciliates (with tens or more). Despite the morphological and size differences between these groups, each of the two probability distributions of swimming speed are accurately represented by log-normal distributions, with good agreement holding even to fourth moments. Scaling of the distributions by a characteristic speed for each data set leads to a collapse onto an apparently universal distribution. These results suggest a universal way for ecological niches to be populated by abundant microorganisms.

description: This paper develops a hedonic model of agricultural land prices to investigate the efficacy of planning controls, whose raison d’être is to regulate the conversion of farmland. While development (commercial, industrial and residential) potential of farmland affects agricultural land values in all countries, its impact is potentially more acute in Newly Industrialised Countries where development pressure is strong and planning law is often weakly enforced. In the Malaysian land market, which epitomises this situation, State Authorities have approved a large number of applications to convert land from agriculture to development, such that the market is inclined to behave as if planning control lacks credibility. To investigate the influence of 'development potential' on land legally designated as agricultural in Malaysia, an extensive dataset of over 2,000 land sales has been assembled. Using this database we attempt to estimate the effect – the development rent – on land price, which turns out to be high, exceeding 400% of agricultural value in some cases. From there, we draw some conclusions regarding the efficacy of existing planning controls and the implications of such a high premium. Der Beitrag untersucht, wie sich Bodenpreise und Landnutzungsentscheidungen im wirtschaftlichen Entwicklungsprozess verändern. Das nichtlandwirtschaftliche Nutzungspotenzial von Agrarflächen für Gewerbe, Industrie- und Wohnzwecke beeinflusst den Kaufpreis von Boden allerorten. Dieser Einfluss ist besonders ausgeprägt in Entwicklungsländern, in denen einerseits der Druck zu Flächenumwidmungen ausgeprägt ist und andererseits Instrumente zur Planung und Regulierung von Nutzungswechseln landwirtschaftlicher Flächen fehlen oder nicht konsequent durchgesetzt werden. Am Beispiel von Malaysia wird gezeigt, dass die unscharfe Umsetzung von Regeln, die dem Erhalt landwirtschaftlicher Flächen dienen, zu Spekulationsprämien führen, die auf eine spätere gewerbliche oder bauliche Nutzung derzeitiger Agrarflächen abzielen. Im Einzelfall kann der Preis landwirtschaftlicher Flächen, für die Marktakteure ein Entwicklungspotenzial sehen, bis zum Vierfachen des rein landwirtschaftlichen Wertes betragen.

How Authentic are our Examination Results? Investigating Causality in Cheating Behaviours and Moral Reasoning among Ghanaian Senior High School Students

description: This was a causal comparative study to investigate the causality of ‘ex post-facto’ variables: moral reasoning (MR) and cheating behaviour (CB) and their associational effect on the authenticity of examination results among Senior High School (SHS) students (N=2,520). Two different data sets were derived from (i) a survey questionnaire with one MR scenario, and (ii) archival WASSCE results of four schools were used to answer four research questions and three null hypotheses raised. Multiple statistical tests of differences including cross tabulations, Chi square, independent sample t-test, and ANOVA were used for analyses focusing on gender and school categories. Differences in MR showed statistical significances among gender [t(2510)=4.83, p=0.00)] and school categories [F(3, 2510)=21.88, p=0.00]. Both positive and negative correlations were rather very low, (ranging between R=0.02 and -0.02). Two of the null hypotheses were rejected at alpha (p=0.05). Four recommendations were put forward for the Ghana’s education system and WAEC the examination authority. Also, practical and policy implications are discussed. Thus, CB was found to have a cause-effect on the authenticity of examination results. But MR levels of SHS students are not solely responsible for CB; rather the schools’ culture of offering ‘helping hands’ creates opportunities for students to cheat at examinations.
Giant nonlinear response of superconducting single crystal niobium in a sweeping magnetic field

description: Giant enhancement of the nonlinear response of a single crystal of Nb placed in a sweeping magnetic field has been experimentally observed. The rectified signal from Nb ($Tc=9.15$ K) has been measured by means of an inductive method as a function of temperature, dc field, dc field sweep rate, and the amplitude of ac field. The Nb sample was excited by an amplitude modulated ac field. Under a stationary regime, the rectified signal appears only for magnetic fields ($H_0$) in the range $H_{c2}H_{c1}$. This experiment shows that the amplitude of the rectified signal is two orders of magnitude larger than the amplitude of the signal seen under stationary field conditions. Moreover, the amplitude of the rectified signal is a power function of the sweep rate, with the power exponent close to 1.

description: In this paper we provide a priori error estimates with explicit constants for both the $L^2$-projection and the Ritz projection onto spline spaces of arbitrary smoothness defined on arbitrary grids. This extends the results recently obtained for spline spaces of maximal smoothness. The presented error estimates are in agreement with the numerical evidence found in the literature that smoother spline spaces exhibit a better approximation behavior per degree of freedom, even for low smoothness of the functions to be approximated. First we introduce results for univariate spline spaces, and then we address multivariate tensor-product spline spaces and isogeometric spline spaces generated by means of a mapped geometry, both in the single-patch and in the multi-patch case.

International Talent for the Arctic: Strategies and Challenges

description: The Arctic region faces a significant demographic challenge, characterized by a population decline and youth outmigration projected until 2060. This phenomenon, driven by harsh climatic conditions, limited economic opportunities, and social isolation, threatens the region's future sustainability and development. Universities play a crucial role in mitigating this challenge by attracting, retaining, and integrating young talent into the Arctic workforce. This study investigates the role of institutional settings in facilitating the integration of highly skilled migrants into the Finnish and Norwegian Arctic regions. This paper explores national higher education strategies, employability support mechanisms and the strategies employed by several prominent Arctic universities, University of Oulu and University of Lapland in Finland, and Nord University in Norway, to retain graduating students and foster their engagement and employment in the corresponding Arctic regions. Employing a comparative case study approach, this study analyzes qualitative and quantitative data, including university strategies, government policies, and regional demographic statistics. Additionally, the analysis incorporates relevant sociological theories on employability and social capital, providing a deeper understanding of the factors that influence youth migration decisions. The study also explores the potential conflict between university-led retention strategies and national-level policies, such as the introduction of tuition fees for non-EU students. This policy change, while generating revenue for universities, might impede international student recruitment and contribute to regional brain drain. Finally, this study questions how universities can embed retention strategies into their core functions and foster sustainable long-term solutions to the demographic challenges of the Arctic regions. By understanding the effectiveness of various strategies and potential challenges, stakeholders can collaborate to develop comprehensive approaches to retaining young talent and creating vibrant, sustainable communities in the Arctic and beyond.
