description: Historical depletion of agricultural soils must be remedied to maintain their long-term food production function, including soils in intensive vineyards traditionally kept without plant cover to limit resource competition. This paper reports on the impact of five contrasting soil management regimes on indicators of soil quality such as soil organic carbon, nitrogen and their indices. We exposed sandy loam Rendzic Leptosol under a vineyard in Nitra-Dražovce (Slovakia, central Europe) to the following five treatments for 14 years: no-till sward, no-till sward+NPK100, no-till sward+NPK125, plowed tillage and (5) plowed tillage+manure. We found that grass swards continuously increased the total soil organic carbon in the topsoil, but plowed tillage resulted in no change. The availability of potentially mineralizable nitrogen was also increased by grass cover; but was not modified by manure but by mineral fertilizer addition. We tested the usefulness of carbon and management indices as indicators of changing soil C and N status and found them no better than tracking total and labile forms of both elements. In conclusion, the recovery of degraded vineyard soils under no-till grass sward cover is detectable within 14 years and is not affected by fertilization or manure addition.

description: Methane dry reforming (DRM) was investigated over highly active Ni catalysts with low metal content (2.5 wt %) supported on Mg-Al mixed oxide. The aim was to minimize carbon deposition and metal sites agglomeration on the working catalyst which are known to cause catalyst deactivation. The solids were characterized using N2 adsorption, X-ray diffraction, temperature-programmed reduction, X-ray photoelectron spectroscopy, and UV-Vis diffuse reflectance spectroscopy. The results showed that MgO-Al2O3 solid solution phases are obtained when calcining Mg-Al hydrotalcite precursor in the temperature range of 550–800 °C. Such phases contribute to the high activity of catalysts with low Ni content even at low temperature (500 °C). Modifying the catalyst preparation with citric acid significantly slows the coking rate and reduces the size of large octahedrally coordinated NiO-like domains, which may easily agglomerate on the surface during DRM. The most effective Ni catalyst shows a stable DRM course over 60 h at high weight hourly space velocity with very low coke deposition. This is a promising result for considering such catalyst systems for further development of an industrial DRM technology.

description: Due to the ongoing change of energy supply, the availability of a reliable high-capacity storage technology becomes increasingly important. While conventional large-scale facilities are either limited in capacity respective supply time or their extension potential is little (e.g., pumped storage power stations), decentralized units could contribute to energy transition. The concepts of PtX (power-to-X) storage technologies and in particular PtG (power-to-gas) aim at fixation of electric power in chemical compounds. CO2 hydrogenation (methanation) is the foundation of the PtG idea as H2 (via electrolysis) and CO2 are easily accessible. Methane produced in this way, often called substitute natural gas (SNG), is a promising solution since it can be stored in the existing gas grid, tanks or underground cavern storages. Methanation is characterized by a strong exothermic heat of reaction which has to be handled safely. This work aims at getting rid of extreme temperature hot-spots in a tube reactor by configuring the catalyst bed structure. Proof of concept studies began with a small tube reactor (V = 12.5 cm3) with a commercial 18 wt % Ni/Al2O3 catalyst. Later, a double-jacket tube reactor was built (V = 452 cm3), reaching a production rate of 50 L/h SNG. The proposed approach not only improves the heat management and process safety, but also increases the specific productivity and stability of the catalyst remarkably.

description: We study infrared contributions to semihard parton-parton interactions by considering an effective charge whose finite infrared behavior is constrained by a dynamical mass scale. Using an eikonal QCD-based model in order to connect this semihard parton-level dynamics to the hadron-hadron scattering, we obtain predictions for the proton-proton ($pp$) and antiproton-proton ($\bar{p}p$) total cross sections, $σ_{tot}^{pp,\bar{p}p}$, and the ratios of the real to imaginary part of the forward scattering amplitude, $ρ^{pp,\bar{p}p}$. We discuss the theoretical aspects of this formalism and consider the phenomenological implications of a class of energy-dependent form factors in the high-energy behavior of the forward amplitude. We introduce integral dispersion relations specially tailored to relate the real and imaginary parts of eikonals with energy-dependent form factors. Our results, obtained using a group of updated sets of parton distribution functions (PDFs), are consistent with the recent data from the TOTEM, AUGER and Telescope Array experiments.

description: The purification of drinking water is one of the most urgent challenges in developing countries, for which the efficient removal of traces of heavy metals, e.g., Cr(IV), represents a key technology. This can be achieved via photocatalysis. In this study, we compare the performance of Au/TiO2 to bare TiO2 P25 catalysts. Furthermore, the influence of the sacrificial reagent citric acid under UV-Vis and Vis excitation was investigated and a detailed investigation of the catalysts before and after reaction was performed. During the photocatalytic reduction of Cr(IV) under acidic conditions, both leaching of Au, as well as absorption of Cr, occur, resulting in new catalyst systems obtained in situ.

description: A thermally decoupled hidden sector of particles, with a mass gap, generically enters a phase of cannibalism in the early Universe. The Standard Model sector becomes exponentially colder than the hidden sector. We propose the Cannibal Dark Matter framework, where dark matter resides in a cannibalizing sector with a relic density set by 2-to-2 annihilations. Observable signals of Cannibal Dark Matter include a boosted rate for indirect detection, new relativistic degrees of freedom, and warm dark matter.

description: The non-Gaussian normal diffusion, i.e., the probability distribution function (PDF) is non-Gaussian but the mean squared displacement (MSD) depends on time linearly, has been observed in particle motions. Here we show by numerical simulations that this phenomenon may manifest in energy diffusion along lattices at a non-zero, finite temperature. The model we study is one-dimensional disordered lattices with on-site potential. We find that the energy-density fluctuations are spatially localized if the nonlinear interaction is suppressed, but may relax with a non-Gaussian PDF and a linear time-dependent MSD when the nonlinear interaction is turned on. Our analysis suggests that the mechanism lies in the delocalization properties of the localized modes.

description: Titanium dioxide (TiO2) is described as an established material to remove pollutants from water. However, TiO2 is still not applied on a large scale due to issues concerning, for example, the form of use or low photocatalytic activity. We present an easily upscalable method to synthesize high active TiO2 nanoparticles on a polyethersulfone microfiltration membrane to remove pollutants in a continuous way. For this purpose, titanium(IV) isopropoxide was mixed with water and hydrochloric acid and treated up to 210 °C. After cooling, the membrane was simply dip-coated into the TiO2 nanoparticle dispersion. Standard characterization was undertaken (i.e., X-ray powder diffraction, scanning electron microscopy, X-ray photoelectron spectroscopy, water permeance, contact angle). Degradation of carbamazepine and methylene blue was executed. By increasing synthesis temperature crystallinity and photocatalytic activity elevates. Both ultrasound modification of nanoparticles and membrane pre-modification with carboxyl groups led to fine distribution of nanoparticles. The ultrasound-treated nanoparticles gave the highest photocatalytic activity in degrading carbamazepine and showed no decrease in degradation after nine times of repetition. The TiO2 nanoparticles were strongly bound to the membrane. Photocatalytic TiO2 nanoparticles with high activity were synthesized. The innovative method enables a fast and easy nanoparticle production, which could enable the use in large-scale water cleaning.
Alumnae Giving and the Internet: An Exploration of Women and ePhilanthropy

description: Previous studies indicate gender differences in both Internet usage and general philanthropic giving. Through a survey of alumni at the University of North Carolina at Chapel Hill, this study seeks to identify how gender differences are reflected when the Internet and philanthropy are combined. Gender differences in philanthropy on the Internet are examined from a public relations perspective, focusing on the importance of relationships and incorporating relevant public relations theories. Findings from this study suggest that there are no significant differences between men and women in their attitudes toward the Internet as a fund-raising and relationship-building tool. The results do indicate, however, that e-mail and the Internet are quickly becoming important communication channels in development and fund raising. Implications for development officers and fund raisers are discussed.

description: We present a detailed phenomenological study of W-boson production in association with a jet through next-to-next-to-leading order (NNLO) in perturbative QCD. Fiducial cross sections and differential distributions for both 8 TeV and 13 TeV LHC collisions are presented, as are results for both the inclusive one-jet bin and the exclusive one-jet bin. Two different event selection criteria are considered: a general selection with standard cuts used in experimental analyses, and a boosted selection that focuses on high transverse momentum jets. We discuss the higher-order corrections in detail and identify for which observables and phase space regions the QCD perturbative expansion is under good theoretical control, and where additional work is needed. For most distributions and phase space regions the QCD perturbative expansion exhibits good convergence after the inclusion of the NNLO corrections.

title: The Role of Stakeholder Engagement in Mediating A Social Licence:  A Case of The UK Shale Gas
titleType: Other
Creators: name: Oruamabo, Pearl
Publisher: name: University of Dundee
Year: 2022

description: A qualitative case study approach was adopted, focusing on the development of shale gas in specific licensed areas. Semi structured interviews and documentary analysis were used to obtain the perspectives of engagement managers, regulators, local communities, Non-Governmental Organisations (NGOs) and industry experts. Collectively, all study participants were stakeholders in the shale gas development process. There was consistency in the understanding of who or what constituted as stakeholders; however, stakeholder engagement was often viewed as prescriptive, serving the interest of the shale gas industry. The implication being that engagement approaches did little to ensure that stakeholder involvement influenced planning and decision making. Friedman and Miles’ ladder of engagement was used to examine the extent of stakeholder engagement in the shale gas development process. The findings indicate that for many stakeholders, contributions to decisions seemed to occur at a tokenistic level, resulting in barriers that further prevent the benefits of stakeholder engagement to be achieved. Insights from the interviewees are analysed in relation to the extent stakeholder engagement can be a legitimising tool. Drawing on the legitimacy theory, this study finds that there are elements of legitimisation in the engagement efforts of the shale gas operators; however, it stops short of finding these efforts successful in achieving legitimacy as a prerequisite of the social licence.

description: Boulders are ubiquitously found on the surfaces of small rocky bodies in the inner solar system and their spatial and size distributions give insight into the geological evolution and collisional history of the parent bodies. Using images acquired by the Chang'e-2 spacecraft, more than 200 boulders have been identified over the imaged area of the near-Earth asteroid Toutatis. The cumulative boulder size frequency distribution (SFD) shows a steep slope of -4.4 $\pm$ 0.1, which is indicative of a high degree of fragmentation. Similar to Itokawa, Toutatis probably has a rubble-pile structure, as most boulders on its surface cannot solely be explained by impact cratering. The significantly steeper slope for Toutatis' boulder SFD compared to Itokawa may imply a different preservation state or diverse formation scenarios. In addition, the cumulative crater SFD has been used to estimate a surface crater retention age of approximately 1.6 $\pm$ 0.3 Gyr.

description: We consider generalized gradient systems in Banach spaces whose evolutions are generated by the interplay between an energy functional and a dissipation potential. We focus on the case in which the dual dissipation potential is given by a sum of two functionals and show that solutions of the associated gradient-flow evolution equation with combined dissipation can be constructed by a split-step method, i.e. by solving alternately the gradient systems featuring only one of the dissipation potentials and concatenating the corresponding trajectories. Thereby the construction of solutions is provided either by semiflows, on the time-continuous level, or by using Alternating Minimizing Movements in the time-discrete setting. In both cases the convergence analysis relies on the energy-dissipation principle for gradient systems.
One-electron self-interaction and the asymptotics of the Kohn-Sham potential: an impaired relation

description: One-electron self-interaction and an incorrect asymptotic behavior of the Kohn-Sham exchange-correlation potential are among the most prominent limitations of many present-day density functionals. However, a one-electron self-interaction-free energy does not necessarily lead to the correct long-range potential. This is here shown explicitly for local hybrid functionals. Furthermore, carefully studying the ratio of the von Weizsäcker kinetic energy density to the (positive) Kohn-Sham kinetic energy density, $τ_\mathrm{W}/τ$, reveals that this ratio, which frequently serves as an iso-orbital indicator and is used to eliminate one-electron self-interaction effects in meta-generalized-gradient approximations and local hybrid functionals, can fail to approach its expected value in the vicinity of orbital nodal planes. This perspective article suggests that the nature and consequences of one-electron self-interaction and some of the strategies for its correction need to be reconsidered.

description: In this work we present CO(1-0) and CO(2-1) observations of a pilot sample of 15 early-type galaxies (ETGs) drawn from the MASSIVE galaxy survey, a volume-limited integral-field spectroscopic study of the most massive ETGs ($M_* >10^{11.5}M_\odot$) within 108 Mpc. These objects were selected because they showed signs of an interstellar medium and/or star formation. A large amount of gas ($>$2$\times$10$^8$ M$_{\odot}$) is present in 10 out of 15 objects, and these galaxies have gas fractions higher than expected based on extrapolation from lower mass samples. We tentatively interpret this as evidence that stellar mass loss and hot halo cooling may be starting to play a role in fuelling the most massive galaxies. These MASSIVE ETGs seem to have lower star-formation efficiencies (SFE=SFR/M$_{\rm H2}$) than spiral galaxies, but the SFEs derived are consistent with being drawn from the same distribution found in other lower mass ETG samples. This suggests that the SFE is not simply a function of stellar mass, but that local, internal processes are more important for regulating star formation. Finally we used the CO line profiles to investigate the high-mass end of the Tully-Fisher relation (TFR). We find that there is a break in the slope of the TFR for ETGs at high masses (consistent with previous studies). The strength of this break correlates with the stellar velocity dispersion of the host galaxies, suggesting it is caused by additional baryonic mass being present in the centre of massive ETGs. We speculate on the root cause of this change and its implications for galaxy formation theories.

In the Name of Conservation

description: This thesis investigates the introduction, adaption, and implementation of the modern concept of heritage conservation in modern China after the opening of its treaty ports. Through an analysis of the different layers of disseminating and receiving knowledge in transnational exchanges, it explicitly points out the divergence between the Eurocentric concept of conservation and the Chinese tradition of treating historic buildings and sites. As a result of the complexity of understanding and adapting an imported idea, the heritage discourse in China is characterised by its own ambiguity. Conservation of modern heritage, in particular those built under colonial power, has seen conflicts of perceptions between conservation planning and interest-led practice. A progressive legislative framework for heritage conservation has had a limited binding effect on stakeholders’ actions to protect listed immovable built cultural heritage sites from artificial damage in China’s contemporary urban practices. By analysing various actors’ interpretations and expressions of the concept of “conservation” (known as “保护” in Chinese) derived from different temporalities, it explores the causes and effects of heritage strategies and approaches created by individuals, groups, and the state apparatus. Theoretically, it challenges the local acceptability of classic conservation principles that are primarily based on European thoughts and cultural background. Practically, it provides adequate clues for a multi-faceted consideration of listed heritage sites in future development. It highlights the significance of creating a powerful local narrative under the authoritative heritage discourse at a crossroads of ongoing globalisation and growing nationalism.

description: Let L be the zero set of a nonconstant monic polynomial with complex coefficients. In the context of constructive mathematics without countable choice, it may not be possible to construct an element of L. In this paper we introduce a notion of distance from a point to a subset, more general than the usual one, that allows us to measure distances to subsets like $L$. To verify the correctness of this notion, we show that the zero set of a polynomial cannot be empty---a weak fundamental theorem of algebra. We also show that the zero sets of two polynomials are a positive distance from each other if and only if the polynomials are comaximal. Finally, the zero set of a polynomial is used to construct a separable Riesz space, in which every element is normable, that has no Riesz homomorphism into the real numbers.

description: Hadron production in semi-inclusive deep-inelastic scattering of leptons from nuclei is an ideal tool to determine and constrain the transport coefficient in cold nuclear matter. The leading-order computations for hadron multiplicity ratios are performed by means of the SW quenching weights and the analytic parameterizations of quenching weights based on BDMPS formalism. The theoretical results are compared to the HERMES positively charged pions production data with the quarks hadronization occurring outside the nucleus. With considering the nuclear geometry effect on hadron production, our predictions are in good agreement with the experimental measurements. The extracted transport parameter from the global fit is shown to be $\hat{q} = 0.74\pm0.03 GeV^2/fm$ for the SW quenching weight without the finite energy corrections. As for the analytic parameterization of BDMPS quenching weight without the quark energy E dependence, the computed transport coefficient is $\hat{q} = 0.20\pm0.02 GeV^2/fm$. It is found that the nuclear geometry effect has a significant impact on the transport coefficient in cold nuclear matter. It is necessary to consider the detailed nuclear geometry in studying the semi-inclusive hadron production in deep inelastic scattering on nuclear targets.

description: We investigate the thermodynamic properties of inner and outer horizons in the background of spinning BTZ(Bañados,Teitelboim and Zanelli) black hole. We compute the \emph{horizon radii product, the entropy product, the surface temperature product, the Komar energy product and the specific heat product} for both the horizons. We observe that the entropy product is \emph{universal}(mass-independent), whereas the surface temperature product, Komar energy product and specific heat product are \emph{not universal} because they all depends on mass parameter. We also show that the \emph{First law} of black hole thermodynamics and \emph {Smarr-Gibbs-Duhem } relations hold for inner horizon as well as outer horizon. The Christodoulou-Ruffini mass formula is derived for both the horizons. We further study the \emph{stability} of such black hole by computing the specific heat for both the horizons. It has been observed that under certain condition the black hole possesses \emph{second order phase transition}.

description: Motivated by the previously reported high orbital decay rate of the planet WASP-43b, eight newly transit light curves are obtained and presented. Together with other data in literature, we perform a self-consistent timing analysis with data covering a timescale of 1849 epochs. The results give an orbital decay rate dP/dt = -0.02890795\pm 0.00772547 sec/year, which is one order smaller than previous values. This slow decay rate corresponds to a normally assumed theoretical value of stellar tidal dissipation factor. In addition, through the frequency analysis, the transit timing variations presented here are unlikely to be periodic, but could be signals of a slow orbital decay.

description: In this paper, I develop a taxonomy of views about how beliefs should be updated in situations of indexical uncertainty. Drawing on previous literature, I show how each view is subject to its own apparent reductio ad absurdum. I argue that two of the three views are more absurd than was previously believed. I argue that the third view—which is held by Bostrom, Elga, Sebens & Carroll, Arntzenius & Dorr, and myself—actually has a pretty good defense against the objection it faces. This matters because the various views have important empirical implications.

description: We report multifrequency phase-referenced observations of the nearby radio galaxy NGC 4261, which has prominent two-sided jets, using the Very Long Baseline Array at 1.4-43 GHz. We measured radio core positions showing observing frequency dependences (known as "core shift") in both approaching jets and counter jets. The limit of the core position as the frequency approaches infinity, which suggests a jet base, is separated by 82$\pm$16 $μ$as upstream in projection, corresponding to (310$\pm$60)Rs (Rs: Schwarzschild radius) as a deprojected distance, from the 43 GHz core in the approaching jet. In addition, the innermost component at the counter jet side appeared to approach the same position at infinity of the frequency, indicating that cores on both sides are approaching the same position, suggesting a spatial coincidence with the central engine. Applying a phase referencing technique, we also obtained spectral index maps, which indicate that emission from the counter jet is affected by free-free absorption (FFA). The result of the core shift profile on the counter jet also requires FFA because the core positions at 5-15GHz cannot be explained by a simple core shift model based on synchrotron self-absorption (SSA). Our result is apparently consistent with the SSA core shift with an additional disk-like absorber over the counterjet side. Core shift and opacity profiles at the counter jet side suggest a two-component accretion: a radiatively inefficient accretion flow at the inner region and a truncated thin disk in the outer region. We proposed a possible solution about density and temperature profiles in the outer disk on the basis of the radio observation.

description: Developing an efficient and robust polarimeter for wide spectral ranges and space applications is a main issue in many projects. As part of the UVMag consortium created to develop UV facilities in space (e.g. the Arago mission proposed to ESA), we are studying an innovative concept of polarimeter that is robust, simple, and efficient on a wide spectral range. The idea, based on the article by Sparks et al. (2012), is to use polarization scramblers to create a spatial modulation of the polarization. Along the height of the wedges of the scramblers, the thickness of the birefringent material crossed by the light, and thus the retardance, vary continuously. This variation creates an intensity modulation of the light related to the entrance polarization state. Analyzing this modulation with a linear polarizer, and dispersing the light spectrally in the orthogonal spatial direction, enables the measurement of the full Stokes vector over the entire spectrum. This determination is performed with a single-shot measurement and without any moving parts in the system. After a quick introduction to the concept and optical design, this article presents the tolerancing study of the optical bench using this spectropolarimeter. The impact of different error sources, such as, birefringence uncertainty or decenter of the wedges, is investigated.

title: Topological coding of single fingerprints
Creators: name: Sparrow, Malcolm K.
Publisher: name: University of Kent

description: The motivation for seeking topological descriptions of single fingerprints is provided by the elasticity of the human skin; successive impressions from the same finger will in-variably have suffered a degree of relative distortion (translation, rotation and stretching). Topology based systems should be free from the detrimental effects of plastic distortion. This thesis is divided into three parts: part I outlines the traditional use of fingerprints as a basis for personal identification and gives detailed explanation of the arguments in favour of topological coding. Methods for the extraction of topology based digital codes are suggested and the ‘placing of lines’ is introduced as an effective means of ordering topological information. In part II specific systems are described for the extraction of simple topological codes from rolled impressions of the pattern types ‘ loops’ , ‘whorls’ and ‘arches’ . The generated codes take the form of vectors or simple digital arrays. The nature and frequency of changes that may occur in such codes is investigated and fingerprint comparison algorithms, based on these topological codes, are developed. The objective of such algorithms is to draw a score derived from the degree of ‘nearness’ of the topological codes in such a manner that it intelligently reflects similarity or dissimilarity in the two prints under comparison. Part III examines the special problems relating to fragmentary ‘scenes-of-crime’ marks. It describes methods of coding fingerprint patterns by a variety of ‘topological coordinate schemes’ , with fingerprint comparison being performed on the basis of localised topological information which is extracted from the recorded coordinate sets. Furthermore, a method for pictorial reconstruction of a complete fingerprint, from its coordinate representation, is demonstrated. Comparison of fingerprints on the basis of digital topological descriptions is shown to offer a substantial improvement in performance over existing (spatial) techniques.
Political and Institutional Constraints on Policy Responses to the Financial Crisis in the United States and the European Union

description: This essay will attempt to explain what caused the variation in policy outputs in response to the financial and economic crisis in the United States and the European Union which began in 2007. Specifically, it will examine the design of fiscal and monetary stimulus in both regions, as well as the development of financial supervisory and regulatory legislation. Ultimately it will be shown that the variation in policy outputs was the result of differing constitutional mandates, relation to public opinion, and dominant policy paradigms at the respective central banks; evolving contemporary political trends; and differing concentrations of legislative power, understood from the perspectives of federalism and multi-level governance.

title: Psychological Contracts at an International Joint Venture University in China.
Creators: name: Galletly, Richard
Publisher: name: University of Liverpool Repository

description: The Psychological Contract (PC) is an important concept within International Human Resource Management which has been defined as an employee’s beliefs about the ‘terms and conditions of a reciprocal exchange agreement’ between an employee and their employer (Rousseau, 1989, p. 123). When managing International Academic Staff (IAS), International Joint Venture Universities (IJVU) must seek to understand the needs and wishes of IAS, to aid retention and to manage them appropriately. Turnover levels of IAS are higher than most IJVUs would like, and therefore this understanding of the PC and PC breach must be understood. This research project explores how IAS working within an IJVU in China experience their PCs and various PC breach, what impacts there are on these IAS and how they respond to any breaches they experience. Working within a Critical Realist meta-theory and framework, this project applies a Critical Grounded Theory analysis to qualitative research within an ethnography of a Higher Education Institution (HEI) in China. Based on qualitative data collected through semi-structured interviews within a single case study Chinese IJVU, new theories about the mechanisms leading to PC breach are developed, through an iterative process between the data, the literature and the researcher’s reflexive process. Findings about the mechanisms leading to PC breach are divided into three levels of reality, according to the Critical Realist framework: cultural, social, and individual levels. Key findings emerge: first, at the cultural level, some IAS learn to fit in and adapt to insider norms and practices common to the local national culture; second, at the social level, some IAS learn to remain loyal towards other insiders, exchanging favours with influential connections and volunteering; third, at the individual level, some IAS experience PC breach due to perceived unfairness and betrayal. The concluding chapter of this report examines how this research contributes to both theory and practice of managing IAS through an understanding of the PC in context, within the case study IVJU and beyond. In summary, this research demonstrates how some IAS are adapting to the context of a Chinese IJVU by fitting in with norms and practices common to the local national culture, remaining loyal to other insiders and nurturing influential connections; those IAS who have found ways to adapt to the national culture may avoid experiencing PC breach and perceived unfairness. This research contributes to the wider discourse about how IAS experience PC breach in Chinese IJVUs and Chinese organisations more generally; furthermore, it suggests ways that IAS can learn to adapt their behaviours to suit the national culture.
A Unified Analysis of "Dative Shift" in English and the Applicative Construction in Chichewa
Creators: name: Rill, Justin

description: Many languages exhibit alternate syntactic realizations of ditransitive verbal constructions. For example, English features both a prepositional construction (Mary gave candy to the children) and a Double Object construction (Mary gave the children candy), a phenomenon known as Dative Shift. In Chichewa, the applicative construction is a similar syntactic alternation. The primary aim of this thesis is to present a unified analysis of Dative Shift and the applicative construction for both of these typologically distinct languages. The proposed unified analysis features an identical argument structure for both languages, as well as isomorphic morphosyntactic processes. It accounts for several asymmetries previously observed between benefactive and instrumental ditransitives in Chichewa. These asymmetries serve as the basis for a corollary hypothesis about natural sub-classes within the class of oblique arguments.

description: Shape transformations of epithelial tissues in three dimensions, which are crucial for embryonic development or in vitro organoid growth, can result from active forces generated within the cytoskeleton of the epithelial cells. How the interplay of local differential tensions with tissue geometry and with external forces results in tissue-scale morphogenesis remains an open question. Here, we describe epithelial sheets as active viscoelastic surfaces and study their deformation under patterned internal tensions and bending moments. In addition to isotropic effects, we take into account nematic alignment in the plane of the tissue, which gives rise to shape-dependent, anisotropic active tensions and bending moments. We present phase diagrams of the mechanical equilibrium shapes of pre-patterned closed shells and explore their dynamical deformations. Our results show that a combination of nematic alignment and gradients in internal tensions and bending moments is sufficient to reproduce basic building blocks of epithelial morphogenesis, including fold formation, budding, neck formation, flattening, and tubulation.
