description: The pursuit of an ideal self and related goals is a constant throughout the lifespan, and a great deal of motivation and self-regulation is required in order to move closer to this ideal. For adolescents in particular, the ability to harness enough motivation to pursue important goals can be a struggle. The current thesis examined the ways in which having close affirming relationships may enhance young people’s ability to pursue their goals, and move closer to their ideal selves. An established inter-personal model of motivation, the Michelangelo Phenomenon, was used as a backdrop for a series of four empirical studies, each building on the previous to further clarify the contributions self-esteem and relationship affirmation make to goal pursuit. The first study extended the concept of relationship affirmation for use in relationships other than romantic couples, to determine whether all forms of affirming relationships could be beneficial to goal pursuit and movement towards the ideal self. This being the case, along with relationship affirmation mediating the positive relation between self-esteem and goal pursuit motivation, the next study extended this further by applying the theory to adolescents undertaking their last years of school. A three time-point school-based study was carried out, testing the mediation hypothesis in adolescents from four Greater London schools. Three empirical chapters describe findings from this study, with Chapters 3 and 4 examining the first time points cross-sectionally, and Chapter 5 analysing the first and last time points longitudinally. The findings revealed relationship affirmation to be a strong predictor of motivation to pursue ideal-relevant goals, and of life satisfaction. The mediation model was supported for the most part, although the pattern was not found longitudinally. The findings reveal the central importance of social support, and particularly the presence of affirming relationships, to enable adolescents to pursue important goals.

description: Il contributo offre un quadro dei risultati della local food policy di Lucca iniziata nel 2019 e giunta alla fine del primo ciclo di attività nel 2022. La Pian del Cibo (questo il suo nome) nasce come politica intercomunale del cibo con cinque comuni aderenti che avevano stipulato una convenzione per la gestione associata. Alla luce delle lezioni intraprese, le amministrazioni comunali rimaste e una parte degli attori coinvolti nel precedente Consiglio del Cibo stanno cercando di far ripartire un nuovo ciclo di attività con un modello di governance profondamente rivisto.

description: It has been suggested that several small-scale structure anomalies in $Λ$CDM cosmology can be solved by strong self-interaction between dark matter particles. It was shown by Braaten and Hammer that the presence of a near threshold S-wave resonance can make the scattering cross section at nonrelativistic speeds come close to saturating the unitarity bound. This can result in the formation of a stable bound state of two asymmetric dark matter particles (we call the bound state as darkonium). Laha and Braaten studied the nuclear recoil energy spectrum in dark matter direct detection experiments due to this incident bound state. Here we study the angular recoil spectrum, and show that it is uniquely determined up to normalization by the S-wave scattering length. Observing this angular recoil spectrum in a dark matter directional detection experiment will uniquely determine many of the low-energy properties of dark matter independent of the underlying dark matter microphysics.

description: Modified gravity models require a screening mechanism to be able to evade the stringent constraints from local gravity experiments and, at the same time, give rise to observable astrophysical and cosmological signatures. Such screened modified gravity models necessarily have dynamics determined by complex nonlinear equations that usually need to be solved on a model-by-model basis to produce predictions. This makes testing them a cumbersome process. In this paper, we investigate whether there is a common signature for all the different models that is suitable to testing them on cluster scales. To do this we propose an observable related to the fifth force, which can be observationally related to the ratio of dynamical-to-lensing mass of a halo, and then show that the predictions for this observable can be rescaled to a near universal form for a large class of modified gravity models. We demonstrate this using the Hu-Sawicki $f(R)$, the Symmetron, the nDGP, and the Dilaton models, as well as unifying parametrizations. The universal form is determined by only three quantities: a strength, a mass, and a width parameter. We also show how these parameters can be derived from a specific theory. This self-similarity in the predictions can hopefully be used to search for signatures of modified gravity on cluster scales in a model-independent way.

EXAMINING SUCCESS FACTORS FOR INNOVATION IN THE MEDICAL DEVICE SPACE: A PATH FORWARD FOR FUTURE ENTREPRENEURS

description: The medical device industry in the United States is a complicated and dynamic business environment. This industry is characterized by some high-profile entrepreneurial successes and many failures. Although innovation and entrepreneurship are well studied in the literature, many existing theories face challenges when scrutinized within the context of medical devices. This thesis explores the determinants of entrepreneurial success in the medical device industry. Two models are considered: one that explains the ability of current medical device startups to receive funding and one that explains the likelihood that a startup will either succeed or fail. The models show that increasing the founders’ LinkedIn followers, focusing on an FDA Class 3 medical device, and being embedded in a robust entrepreneurial ecosystem are all significant and positive factors for determining funding. In addition, having more founders and including a founder with a medical degree both increase the likelihood of startup success.

description: Il punto chiave di “decostruzione” critica rispetto al discorso che riguarda il corrente e prevalente sistema di produzione, distribuzione e consumo del cibo si concentra sulla necessità di superamento della progressiva assimilazione di questo ad una “commodities” e degli effetti ecosistemici e sociali negativi che ciò ha prodotto. La visione alternativa propone di ricondurre tale bene alla sua natura di commons, come sistema socio-ecologico multidimensionale, inclusivo ed espressivo di valori che stanno alla base dello stesso patto sociale. In questo quadro il contributo esplora le possibili implicazioni in termini di “re-embedding” del sistema locale del cibo considerato in riferimento al recupero della sua dimensione territoriale attraverso il concetto di “bacino del cibo” come fattore induttivo di valori e criteri per nuove forme di governance locale, sondando la sussistenza di tali principi nelle più recenti forme di costituzione di Comunità del cibo nella regione Toscana.

description: Facing an inexorable growth of the human population along with substantial environmental changes, the assurance of food security is a major challenge of the present century. To ensure responsible food consumption and production (SDG 12), new approaches in the food system are required. Thus, environmentally controlled, sustainable production of alternative food sources are of key interest for both urban agriculture and food research. To face the current challenge of integrating food production systems within existing structures, multidisciplinary discourses are required. Here, we bring together novel technologies and indoor farming techniques with the aim of supporting the development of sustainable food production systems. For this purpose, we investigated the feasibility of 10 composite materials for their innovative use as structural support in macroalgal cultivation (settlement substrates) and cricket rearing (housing). Considering material resistance, rigidity, and direct material-organism interactions, the bio-based composite polylactic acid (PLA) was identified as a suitable material for joint farming. For macroalgae cultivation, PLA sustained the corrosive cultivation conditions and provided a suitable substrate without affecting the macroalgal physiology or nutritional composition (carotenoids and chlorophylls). For cricket rearing, PLA provided a suitable and recyclable shelter, which was quickly accepted by the animals without any observed harm. In contrast, other common composite components like phenolic resin or aramid were found to be unsuitable due to being harmful for the cultivated organisms or instable toward the applied sterilization procedure. This multidisciplinary study not only provides profound insights in the developing field of urban indoor food production from a new perspective, but also bridges material science and farming approaches to develop new sustainable and resilient food production systems.

description: False smut disease (FSD) of rice incited by Ustilaginoidea virens is an emerging threat to paddy cultivation worldwide. We investigated the spatial distribution of FSD in different paddy ecosystems of South Indian states, viz., Andhra Pradesh, Karnataka, Tamil Nadu, and Telangana, by considering the exploratory data from 111 sampling sites. Point pattern and surface interpolation analyses were carried out to identify the spatial patterns of FSD across the studied areas. The spatial clusters of FSD were confirmed by employing spatial autocorrelation and Ripley’s K function. Further, ordinary kriging (OK), indicator kriging (IK), and inverse distance weighting (IDW) were used to create spatial maps by predicting the values at unvisited locations. The agglomerative hierarchical cluster analysis using the average linkage method identified four main clusters of FSD. From the Local Moran’s I statistic, most of the areas of Andhra Pradesh and Tamil Nadu were clustered together (at I > 0), except the coastal and interior districts of Karnataka (at I < 0). Spatial patterns of FSD severity were determined by semi-variogram experimental models, and the spherical model was the best fit. Results from the interpolation technique, the potential FSD hot spots/risk areas were majorly identified in Tamil Nadu and a few traditional rice-growing ecosystems of Northern Karnataka. This is the first intensive study that attempted to understand the spatial patterns of FSD using geostatistical approaches in India. The findings from this study would help in setting up ecosystem-specific management strategies to reduce the spread of FSD in India.

Year: 2019

description: Carl Barks, the most influential chronicler of the Duckburg universe and the creator of such memorable characters as Scrooge McDuck, only very rarely made references to classical antiquity in his comic stories. Nevertheless, there is a striking resemblance between ideas propounded in "Plutos," Aristophanes’ last extant comedy of 388 B.C., and “A Financial Fable,” a story by Barks published in 1951. Both stories feature protagonists wishing for universal wealth, and in both this financial utopia is contrasted with a demonstration how such a state of affairs would inevitably bring all human productivity to a halt. Such parallels, even if not the result of direct reception, lead to a set of questions regarding the political coloring of humor and its ideological implications.

description: We explore the quantum dynamics of a one-dimensional trapped ultracold ensemble of bosonic atoms triggered by the sudden creation of a single ion. The numerical simulations are performed by means of the ab initio multiconfiguration time-dependent Hartree method for bosons which takes into account all correlations. The dynamics is analyzed via a cluster expansion approach, adapted to bosonic systems of fixed particle number, which provides a comprehensive understanding of the occurring many-body processes. After a transient during which the atomic ensemble separates into fractions which are unbound and bound with respect to the ion, we observe an oscillation in the atomic density which we attribute to the additional length and energy scale induced by the attractive long-range atom-ion interaction. This oscillation is shown to be the main source of spatial coherence and population transfer between the bound and the unbound atomic fraction. Moreover, the dynamics exhibits collapse and revival behavior caused by the dynamical build-up of two-particle correlations demonstrating that a beyond mean-field description is indispensable.

description: This article deals with the detection and projection of spatial patterns in text collections. Especially for historical corpora, researchers face a lack of general-purpose tooling. In these experiments, different maps focusing on Brandenburg at the second half of the 19th century are created based on literary works by Theodor Fontane. Using a common ground for hypothesis testing and visualization, issues related to data curation and preparation, text processing and geocoding are presented and discussed: the abstract, static nature of the results should be made up for by particular scrutiny and contextualization, by critical machine reading and by adding depth through visual cues.

description: Interacting bosons with two "spin'' states in a lattice show novel superfluid-insulator phase transitions in the presence of spin-orbit coupling. Depending on the parameter regime, bosons in the superfluid phase can condense to either a zero momentum state or to one or multiple states with finite momentum, leading to an unconventional superfluid phase. We study the response of such a system to modulation of the optical lattice potential. We show that the change in momentum distribution after lattice modulation shows distinct patterns in the Mott and the superfluid phase and these patterns can be used to detect these phases and the quantum phase transition between them. Further, the momentum resolved optical modulation spectroscopy can identify both the gapless (Goldstone) gapped amplitude (Higgs) mode of the superfluid phase and clearly distinguish between the superfluid phases with a zero momentum condensate and a twisted superfluid phase by looking at the location of these modes in the Brillouin zone. We discuss experiments which can test our theory.

description: In this article, we investigate the energy landscape and metastable behavior of the Ising and Potts models on two-dimensional square or hexagonal lattices in the low temperature regime, especially in the absence of an external magnetic field. The energy landscape of these models without an external field is known to have a huge and complex saddle structure between ground states. In the small volume regime where the lattice is finite and fixed, the aforementioned complicated saddle structure has been successfully analyzed in [20] for two or three dimensional square lattices when the inverse temperature tends to infinity. In this article, we consider the large volume regime where the size of the lattice grows to infinity. We first establish an asymptotically sharp threshold such that the ground states are metastable if and only if the inverse temperature is larger than the threshold in a suitable sense. Then, we carry out a detailed analysis of the energy landscape and rigorously establish the Eyring-Kramers formula when the inverse temperature is sufficiently larger than the previously mentioned sharp threshold. The proof relies on detailed characterization of dead-ends appearing in the vicinity of optimal transitions between ground states and on combinatorial estimation of the number of configurations lying on a certain energy level.

description: On the basis of the representation of the generalized structure of nucleons a new model of the hadron interaction at high energies is presented. The new t-dependence of the generalized parton distributions (GPDs) is obtained from the comparative analysis of different sets of the parton distribution functions (PDFs), based on the description of the whole sets of experimental data of electromagnetic form factors of the proton and neutron. Taking into account the different moments of GPDs of the hadron the quantitative descriptions of all existing experimental data of the proton-proton and proton-antiproton elastic scattering from $\sqrt{s} = 9.8$ GeV to $ 8 \ $ TeV, including the Coulomb range and large momentum transfers up to $-t=15$ GeV$^2$, are obtained with a few free fitting high energy parameters. The real part of the hadronic elastic scattering amplitude is determined only through complex $s$ satisfying the dispersion relations. The negligible contributions of the hard Pomeron and the presence of the non-small contributions of the maximal Odderon are obtained. The non-dying form of the spin-flip amplitude is examined as well. The structure of the Born term and unitarized scattering amplitude are analysed. It is shown that the Black Disk Limit for the elastic scatering amplitude is not reached at LHC energies. Predictions for LHC energies are made.

description: We present a CARMA 1.3 mm continuum survey toward 9 Class 0 protostars in the Perseus molecular cloud at $\sim$0.3$^{\prime\prime}$ (70 AU) resolution. This study approximately doubles the number of Class 0 protostars observed with spatial resolutions $$ 100 AU around 2 sources (L1448 IRS2 and Per-emb-14) and these sources may be strong disk candidates. Marginally-resolved structures with position angles within 30$^{\circ}$ of perpendicular to the outflow are found toward 3 protostars (L1448 IRS3C, IRAS 03282+3035, and L1448C) and are considered disk candidates. Two others (L1448 IRS3B and IRAS 03292+3039) have resolved structure, possibly indicative of massive inner envelopes or disks; L1448 IRS3B also has a companion separated by 0.9$^{\prime\prime}$ ($\sim$210 AU). IC348-MMS does not have well-resolved structure and the candidate first hydrostatic core L1451-MMS is marginally resolved on 1$^{\prime\prime}$ scales. The strong disk candidate sources were followed-up with C$^{18}$O ($J=2\rightarrow1$) observations, detecting velocity gradients consistent with rotation, but it is unclear if the rotation is Keplerian. We compare the observed visibility amplitudes to radiative transfer models, finding that visibility amplitude ratios suggest a compact component (possibly a disk) is necessary for 5 of 9 Class 0 sources; envelopes alone may explain the other 4 systems. We conclude that there is evidence for the formation of large disks in the Class 0 phase with a range of radii and masses dependent upon their initial formation conditions.

description: Tra l’inverno 2022 e la primavera 2023, in seguito a un protocollo d’intesa siglato tra il Comune e l’Università di Padova, si è svolta la ricerca intitolata “Azioni preliminari all’avvio di una politica del cibo nel Comune di Padova”. È così stata realizzata una prima mappatura dei soggetti che in città si occupano di politiche del cibo sostenibile; si è quantificata la capacità di contenimento dello spreco alimentare da parte di questi attori, e sono state identificate delle proposte concrete da rivolgere all’amministrazione sul tema. L’indagine sugli sprechi è stata poi estesa anche alla grande distribuzione. L’articolo racconta i risultati della ricerca, che pongono le basi per l’avvio di una politica alimentare, proprio mentre il Comune di Padova sta istituendo un gruppo di lavoro intersettoriale per la redazione di un Piano del cibo.


Between the winter of 2022 and the spring of 2023, following a memorandum of understanding signed between the City and the University of Padua, research entitled “Preliminary Actions to a Food Policy in the City of Padua” was carried out. Thus, an initial mapping of the actors involved in sustainable food policies in the city was carried out; the capacity of these actors to curb food waste was quantified, and concrete proposals to the administration on this issue were identified. The waste survey was then extended to include large retailers. The article recounts the results of the research, which lay the groundwork for the launch of a food policy, just as the City of Padua is establishing an intersectoral working group to draft a Food Plan.

description: While the Sauter-Schwinger effect describes nonperturbative electron-positron pair creation from vacuum by a strong and slowly varying electric field $E_{\mathrm{strong}}$ via tunneling, the dynamically assisted Sauter-Schwinger effect corresponds to a strong (exponential) enhancement of the pair-creation probability by an additional weak and fast electric or electromagnetic pulse $E_{\mathrm{weak}}$. Using the WKB and worldline instanton method, we find that this enhancement mechanism strongly depends on the shape of the fast pulse. For the Sauter profile $1/\cosh^2(ωt)$ considered previously, the threshold frequency $ω_{\mathrm{crit}}$ (where the enhancement mechanism sets in) is basically independent of the magnitude $E_{\mathrm{weak}}$ of the weak pulse---whereas for a Gaussian pulse $\exp(-ω^2t^2)$, an oscillating profile $\cos(ωt)$ or a standing wave $\cos(ωt)\cos(kx)$, the value of $ω_{\mathrm{crit}}$ does depend (logarithmically) on $E_{\mathrm{weak}}/E_{\mathrm{strong}}$.

description: A general mechanism is presented by which topological physics arises in strongly correlated systems without flat bands. Starting from a charge transfer insulator, topology emerges when the charge transfer energy between the cation and anion is reduced to invert the lower Hubbard band and the spin-degenerate charge transfer band. A universal low-energy theory is developed for the inversion of charge transfer gap in a quantum antiferromagnet. The inverted state is found to be a quantum anomalous Hall (QAH) insulator with non-coplanar magnetism. Interactions play two essential roles in this mechanism: producing the insulating gap and quasiparticle bands prior to the band inversion, and causing the change of magnetic order necessary for the QAH effect after inversion. Our theory explains the electric field induced transition from correlated insulator to QAH state in AB-stacked TMD bilayer MoTe$_2$/WSe$_2$.

description: The classification of galaxy mergers and isolated disks is key for understanding the relative importance of galaxy interactions and secular evolution during the assembly of galaxies. The kinematic properties of galaxies as traced by emission lines have been used to suggest the existence of a significant population of high-z star-forming galaxies consistent with isolated rotating disks. However, recent studies have cautioned that post-coalescence mergers may also display disk-like kinematics. To further investigate the robustness of merger/disk classifications based on kinematic properties, we carry out a systematic classification of 24 local (U)LIRGs spanning a range of galaxy morphologies: from isolated spiral galaxies, ongoing interacting systems, to fully merged remnants. We artificially redshift the WiFeS observations of these local (U)LIRGs to z=1.5 to make a realistic comparison with observations at high-z, and also to ensure that all galaxies have the same spatial sampling of ~900 pc. Using both kinemetry-based and visual classifications, we find that the reliability of kinematic classification shows a strong trend with the interaction stage of galaxies. Mergers with two nuclei and tidal tails have the most distinct kinematic properties compared to isolated disks, whereas a significant population of the interacting disks and merger remnants are indistinguishable from isolated disks. The high fraction of late-stage mergers showing disk-like kinematics reflects the complexity of the dynamics during galaxy interactions. However, the exact fractions of misidentified disks and mergers depend on the definition of kinematic asymmetries and the classification threshold when using kinemetry-based classifications. Our results suggest that additional indicators such as morphologies traced by stars or molecular gas are required to further constrain the merger/disk classifications at high-z.

Characterizing Multi-Decadal Trends in Streamflow and Design Floods in the Southeastern United States

description: Design floods serve an important role in environmental planning and management; however, flood frequency analyses often assume that historical records are stationary despite anthropogenic changes across the watershed. Such changes are especially prevalent in the southeastern United States where rapid population growth coupled with climate change is dramatically altering catchment response. To understand how design floods have changed over time, this study investigates historical records of daily river discharge at over 5,800 USGS gauges in the Southeastern USA. When looking at trends in daily discharges, we find that 40% experienced a significant (p<0.05) increase in daily discharge, 50% experienced significant decrease, and 10% experienced no significant change in daily discharge. We observe that, in general, gages exhibiting increasing daily discharge are spatially concentrated east of the Appalachian Mountains and gages exhibiting decreasing daily discharge are spatially concentrated to the west. When looking at trends in extreme discharges using both the annual maxima and a peak-over-threshold with discharges above the 90th and 99th percentiles, we find that less than 20% of gages had a significant trend in the extreme discharges. We then conducted a flood frequency analysis at gages with the most significant (positive and negative) trends in daily discharge to estimate the 25- 50- and 100-year design flows using the Gumbel distribution based. We compare the modeled results using the annual maxima over the entire period of record and for every 30-year segment of the record. For all return periods, we find that about 75% of gages experienced a significant trend, with 50% of gages experiencing an increasing trend in the magnitude of the design flood. Future work will look to attribute our observed trends to changes in the watershed including urbanization and climate change. Understanding non-stationary trends in river discharge, especially in coastal zone, is critical for local government planning and adaptation in light of changing coastal hazards.

Binary black hole mergers from young massive clusters in the pair-instability supernova mass gap

description: The recent discovery of the binary black hole (BBH) merger event GW190521, between two black holes (BHs) of $\approx100M_\odot$, and as well as other massive BBH merger events involving BHs within the pair-instability supernova (PSN) mass gap have sparked widespread debate on the origin of such extreme gravitational-wave (GW) events. In this study, I investigate whether dynamical interactions in young massive clusters (YMCs) serves as a viable scenario for assembling PSN-gap BBH mergers. To that end, I explore a grid of 40 new evolutionary models of a representative YMC of initial mass $M_{\rm cl}=7.5\times10^4M_\odot$ ($N\approx1.28\times10^5$) and size $r_h=2$ pc, with all BH progenitor stars being initially in primordial binaries. All cluster models are evolved with the direct, relativistic N-body code NBODY7 incorporating up to date remnant formation, BH natal spin, and general-relativistic (GR) merger recoil schemes. The BBH mergers from these model cluster computations agree well with the masses and effective spin parameters of the GW events in the latest GW transient catalogue (GWTC). In particular, GW190521-like, i.e., $\approx200M_\odot$, low aligned spin events are produced via dynamical merger among BHs derived from star-star merger products. GW190403-like, i.e., PSN-gap, highly asymmetric and aligned events result from mergers involving BHs that are spun up via matter accretion or binary interaction. The present YMC models yield a present day, intrinsic merger rate density of $0-3.8\times10^{-2}{{\rm~yr}^{-1}{\rm Gpc}^{-3}}$ for GW190521-type events. They produce GW190403-like events at a rate within $0-1.6\times10^{-1}{{\rm~yr}^{-1}{\rm Gpc}^{-3}}$ and their total BBH-merger yield within the PSN gap is $0-8.4\times10^{-1}{{\rm~yr}^{-1}{\rm Gpc}^{-3}}$.

description: 100 Years Berlin Alexanderplatz is a study of the changes in interpretations of Alfred Döblin's seminal novel Berlin Alexanderplatz with particular attention to the role of disability. It addresses Rainer Werner Fassbinder's 1980 film series as well as Burhan Qurbani's 2020 film of the same name. The work shows how differences in time period and author affect how each work treats disability and different intersectional issues, such as gender and race.
Dispersion for Two Classes of Random Variables: General Theory and Application to Inference of an External Ligand Concentration by a Cell

description: We derive expressions for the dispersion for two classes of random variables in Markov processes. Random variables like current and activity pertain to the first class, which is composed by random variables that change whenever a jump in the stochastic trajectory occurs. The second class corresponds to the time the trajectory spends in a state (or cluster of states). While the expression for the first class follows straightforwardly from known results in the literature, we show that a similar formalism can be used to derive an expression for the second class. As an application, we use this formalism to analyze a cellular two-component network estimating an external ligand concentration. The uncertainty related to this external concentration is calculated by monitoring different random variables related to an internal protein. We show that, inter alia, monitoring the time spent in the phosphorylated state of the protein leads to a finite uncertainty only if there is dissipation, whereas the uncertainty obtained from the activity of the transitions of the internal protein can reach the Berg and Purcell limit even in equilibrium.
