description: We classify topological defects in non-Hermitian systems with point gap, real gap and imaginary gap for all the Bernard-LeClair classes or generalized Bernard-LeClair classes in all dimensions. The defect Hamiltonian $H(\bf{k}, {\bf r})$ is described by a non-Hermitian Hamiltonian with spatially modulated adiabatical parameter ${\bf r}$ surrounding the defect. While the non-Hermitian system with point gap belongs to any of 38 symmetry classes (Bernard-LeClair classes), for non-Hermitian systems with line-like gap we get 54 non-equivalent generalized Bernard-LeClair classes as a natural generalization of point gap classes. Although the classification of defects in Hermitian systems has been explored in the context of standard ten-fold Altland-Zirnbauer symmetry classes, a complete understanding of the role of the general non-Hermitian symmetries on the topological defects and their associated classification are still lacking. By continuous transformation and homeomorphic mapping, these non-Hermitian defect systems can be mapped to topologically equivalent Hermitian systems with associated symmetries, and we get the topological classification by classifying the corresponding Hermitian Hamiltonians. We discuss some non-trivial classes with point gap according to our classification table, and give explicitly the topological invariants for these classes. We also study some lattice or continuous models and discuss the correspondence between the topological number and zero modes at the topological defect.

Bottom-Up Management: Participative Philosophy and Humanistic Psychology in American Organizational Culture, 1930-1970

description: This dissertation examines the rise and fall of participative and humanistic management in American organizational culture. In the years surrounding World War II, an influential network of psychologists and human-relations experts successfully promoted the idea that managers' involvement of subordinates in decision-making, along with their cultivation of underlings' authentic self-expression, would boost the effectiveness of organizations, individuals, and the nation as a whole. Four men proved particularly influential in this endeavor: German social psychologist Kurt Lewin (co-founder of the National Training Laboratories), survey pioneer Rensis Likert (founder of the Institute for Social Research at the University of Michigan), humanistic psychologist Abraham Maslow (developer of the "hierarchy of needs"), and industrial psychologist Douglas McGregor (author of The Human Side of Enterprise). Each of these men was deeply concerned about the fate of democracy in modern society, which they feared was endangered by both authoritarianism abroad and bureaucratic dehumanization at home. Each insisted that the nurturing of participation and "self-actualization" within organizations could help build an increasingly peaceful order in industry and the world at large. Ultimately, they found their most enthusiastic converts within the corner offices and personnel departments of corporations. The dissertation argues that for roughly two and a half decades after World War II, this network of anti-fascist, pro-democratic theorists and practitioners injected their idealism into corporate culture and ultimately recast popular expectations for the relationship between organizational work and selfhood. These theorists' ability to make humanistic and participative management palatable to industrial leaders- largely through promises of intertwined psychological and economic growth -offered them significant inroads into mainstream organizational culture and helped shape a humanistic rhetoric of personal growth that still thrives in some corporations today.

description: Theoretical predictions for elastic neutrino-electron scattering have no hadronic or nuclear uncertainties at leading order making this process an important tool for normalizing neutrino flux. However, the process is subject to large radiative corrections that differ according to experimental conditions. In this paper, we collect new and existing results for total and differential cross sections accompanied by radiation of one photon, $νe \to νe (γ)$. We perform calculations within the Fermi effective theory and provide analytic expressions for the electron energy spectrum and for the total electromagnetic energy spectrum as well as for double- and triple-differential cross sections with respect to electron energy, electron angle, photon energy, and photon angle. We discuss illustrative applications to accelerator-based neutrino experiments and provide the most precise up-to-date values of neutrino-electron scattering cross sections. We present an analysis of theoretical error, which is dominated by the $\sim 0.2 - 0.4\%$ uncertainty of the hadronic correction. We also discuss how searches for new physics can be affected by radiative corrections.

description: Binary collision simulations of high-fluence 1 keV Si ion implantation into 8 nm thick SiO2 films on (001)Si were combined with kinetic Monte Carlo simulations of Si nanocrystal (NC) formation by phase separation during annealing. For nonvolatile memory applications, these simulations help to control size and location of NCs. For low concentrations of implanted Si, NCs form via nucleation, growth and Ostwald ripening, whereas for high concentrations Si separates by spinodal decomposition. In both regimes, NCs form above a thin NC free oxide layer at the SiO2/Si interface. This, self-adjusted layer has just a thickness appropriate for NC charging by direct electron tunneling. Only in the nucleation regime the width of the tunneling oxide and the mean NC diameter remain constant during a long annealing period. This behavior originates from the competition of Ostwald ripening and Si loss to the Si/SiO2 interface. The process simulations predict that, for nonvolatile memories, the technological demands on NC synthesis are fulfilled best in the nucleation regime.

Boucher's Bijoux: Luxury Reproduction in the Age of Enlightenment

description: This dissertation examines the translation of paintings and drawings by François Boucher (1703–1770) into luxury media. Eighteenth-century collectors expended small fortunes on precious objects that reproduced Boucher’s work: cameos, intaglios, enamel-painted porcelain vessels, gold boxes, biscuit porcelain figurines, wool and silk tapestries, and furniture upholstery. Existing studies of eighteenth-century reproduction have tended to focus on innovations in printmaking that enabled the production of inexpensive and extremely faithful facsimiles of works of art. Luxury reproductions, by contrast, were expensive, scarce, and materially assertive, often calling attention to their mediums, and to the act of mediation itself. Through an investigation of the morphological, material, and temporal stakes of these intermedial translations, I show that luxury copies were not derivative substitutes for absent originals, but rather were generative tools of social, artistic, and political identity construction. A central figure in this story is the royal mistress Madame de Pompadour (1721–1764), who was an avid collector of Boucher’s work (and of reproductions after his work), and who reproduced his cameos and intaglios in a limited-edition set of engravings. Through her engravings and decorative installations, Pompadour demonstrated a keen interest in the material processes of transmission and the agency of media. I examine Pompadour’s work and patronage in relation to her political identity as a mediator between the court and the king. Boucher was the perfect collaborator in Pompadour’s project; the material processes of intermedial translation often became the very subject of his work. Boucher’s and Pompadour’s deep investment in the materiality of mediation demands that we revise our understanding of the Rococo “unity of the arts,” which too often is attributed to a dematerialized mobility.

description: Accurate predictions of pollutant concentrations at new locations are often of interest in air pollution studies on fine particulate matters (PM$_{2.5}$), in which data is usually not measured at all study locations. PM$_{2.5}$ is also a mixture of many different chemical components. Principal component analysis (PCA) can be incorporated to obtain lower-dimensional representative scores of such multi-pollutant data. Spatial prediction can then be used to estimate these scores at new locations. Recently developed predictive PCA modifies the traditional PCA algorithm to obtain scores with spatial structures that can be well predicted at unmeasured locations. However, these approaches require complete data, whereas multi-pollutant data tends to have complex missing patterns in practice. We propose probabilistic versions of predictive PCA which allow for flexible model-based imputation that can account for spatial information and subsequently improve the overall predictive performance.

description: Filamentous temperature-sensitive protein Z (FtsZ), playing a key role in bacterial cell division, is regarded as a promising target for the design of antimicrobial agent. This study is looking for potential high-efficiency FtsZ inhibitors. Ligand-based pharmacophore and E-pharmacophore, virtual screening and molecular docking were used to detect promising FtsZ inhibitors, and molecular dynamics simulation was used to study the stability of protein-ligand complexes in this paper. Sixty-three inhibitors from published literatures with pIC50 ranging from 2.483 to 5.678 were collected to develop ligand-based pharmacophore model. 4DXD bound with 9PC was selected to develop the E-pharmacophore model. The pharmacophore models validated by test set method and decoy set were employed for virtual screening to exclude inactive compounds against ZINC database. After molecular docking, ADME analysis, IFD docking and MM-GBSA, 8 hits were identified as potent FtsZ inhibitors. A 50 ns molecular dynamics simulation was implemented on the compounds to assess the stability between potent inhibitors and FtsZ. The results indicated that the candidate compounds had a high docking score and were strongly combined with FtsZ by forming hydrogen bonding interactions with key amino acid residues, and van der Waals forces and hydrophobic interactions had significant contribution to the stability of the binding. Molecular dynamics simulation results showed that the protein-ligand compounds performed well in both the stability and flexibility of the simulation process.
Stimuli-induced folding cascade of a linear oligomeric guest chain programmed through cucurbit[n]uril self-sorting (n = 6, 7, 8)

description: A six-station linear guest for cucurbit[7]uril and cucurbit[8]uril has been synthesized in order to implement a cascade of transformations driven by external stimuli. The guest chain is sequence-programmed with electron- deficient viologen and electron-rich naphthalene stations linked by either flexible or rigid spacers that affect the chain's folding properties. Together with the orthogonal guest selectivity of the two cucurbiturils, these properties result in self-sorted cucurbituril pseudorotaxane foldamers. Each transformation is controlled by suitable chemical and redox inputs and leads not only to refolding of the guest chain, but also to the liberation of secondary messenger molecules which render the system presented here reminiscent of natural signaling cascades. The steps of the cascade are analyzed by UV/Vis, 1H NMR and electrospray (tandem) mass spectrometry to investigate the different pseudorotaxane structures in detail. With one guest oligomer, three different cucurbiturils, and several different chemical and redox inputs, a chemical system is created which exhibits complex behavior beyond the chemist's paradigm of the pure chemical compound.

description: Each choice of a Kähler class on a compact complex manifold defines an action of the Lie algebra $\slt$ on its total complex cohomology. If a nonempty set of such Kähler classes is given, then we prove that the corresponding $\slt$-copies generate a semisimple Lie algebra. We investigate the formal properties of the resulting representation and we work things out explicitly in the case of complex tori, hyperkähler manifolds and flag varieties. We pay special attention to the cases where this leads to a Jordan algebra structure or a graded Frobenius algebra.

description: The non-observation of Hawking radiation from primordial black holes of $10^{16}$g sets a conservative strong bound on their cosmological abundance. We revisit this bound and show how it can be improved (both in mass reach and strength) by an adequate modeling of the combined AGN and blazar emission in the MeV range. We also estimate the sensitivity to the primordial black hole abundance of a future X-ray experiment capable of identifying a significantly larger number of astrophysical sources contributing to the diffuse background in this energy range.

description: Over the last two decades, the literary world has seen many new works by Kurdish writers and poets who have authored works of fiction, memoir and collections of poetry in the English language. This thesis, Roots and Routes: Kurdish Literature as World Literature, is the study of this body of work. As the first comprehensive study to cover the existing and emerging Kurdish Anglophone writings, this study introduces these writings into the arena of world literatures in English. However, it also identifies these works as a new literary canon in the realm of Kurdish literature. This study is an attempt to investigate why and how these Anglophone Kurdish writings emerged, who their intended readers are, and what roles these writings play or can play. To find answer to these questions, this study examines both the contexts out of which and in which these writings have emerged. It positions them in the historical and geopolitical contexts they have emerged from and examines the new and broader cultural, literary and socio-political contexts in which they have been produced, circulated and received. Looking at these two contexts, this study finds that these writings have created and can continue to create new spaces of global engagement with the Kurdish question(s) and Kurdish people. It asserts that these writings entail a kind of activism and create an arena of struggle and Kurdish voice of resistance beyond their imposed national borders, in the wider context of the world. It is within this context that this study argues for this body of work as a new discursive space of negotiation and recognition of the Kurdish questions and Kurdish people in global and transnational contexts. In its reading of the texts, this study, drawing on various theoretical frameworks and taking a reception-based or readerly pragmatics approach, aims to explore how these texts interact with their implied readers and the ways they might be read. It seeks to explore not only why but also and more significantly how these writings of different genres bear witness to Kurdish traumatic history and act as testimony. In short, it looks at both politics and poetics of witnessing and testimony in the emerging Anglophone writings by Kurdish diaspora authors.

description: Anomalies near the conductance threshold of nearly perfect semiconductor quantum wires are explained in terms of singlet and triplet resonances of conduction electrons with a single weakly-bound electron in the wire. This is shown to be a universal effect for a wide range of situations in which the effective single-electron confinement is weak. The robustness of this generic behavior is investigated numerically for a wide range of shapes and sizes of cylindrical wires with a bulge. The dependence on gate voltage, source-drain voltage and magnetic field is discussed within the framework of an extended Hubbard model. This model is mapped onto an extended Anderson model, which in the limit of low temperatures is expected to lead to Kondo resonance physics and pronounced many-body effects.

description: Atractylodes lancea is a type of typical traditional Chinese medicinal (TCM) herb that is economically important in China. The traditional planting method of A. lancea is to plant in situ continuously for many years, which often leads to impediments for its growth and development and soil-borne diseases. The root-associated microbiome is believed to play an important role in plant resistance and the quality of products from the plant. This study aims to reveal detailed changes in the populations of rhizosphere microorganisms, and providing theoretical guidance for the prevention and control of soil-borne diseases in A. lancea. A high-throughput sequencing approach was utilized to illustrate changes in the microbial community from different planting years. Results and conclusions: The results show that the diversity and composition of the root-associated microbiome was significantly impacted by the consecutive monoculture of A. lancea. At the level of the comparisons of the phyla, Bacteroidetes, Proteobacteria, Ascomycota, and Basidiomycota declined significantly. In contrast, the relative abundance of Actinobacteria, Acidobacteria, and Mortierellomycota distinctly increased. Comparisons at the genus level indicated that Sphingomonas, Flavobacterium, Pseudomonas, Pedobacter, and Tausonia decreased significantly, whereas Mortierella, Cylindrocarpon, Dactylonectria, and Mucor distinctly increased. In conclusion, this study helps to develop an understanding of the impediments involved in the consecutive monoculture of A. lancea.

description: Diabetic ketoacidosis (DKA) is a life-threatening complication of diabetes mellitus (DM). The standard method of detection of ketone bodies is the dipstick method, which detects semiquantitatively acetoacetate, but not β-hydroxybutyrate (β-HB). The objectives of the current study were to assess the diagnostic utility of β-HB to diagnose diabetic ketosis (DK) and DKA in cats and to establish a cut-off value for the diagnosis of DKA. Sixty-two cats were included in the study. Eleven cats were healthy (group 1); in the remainder of cats (51), a diagnosis of DM was based on hyperglycemia, glucosuria, and increased fructosamine concentrations. Nineteen of 51 cats suffered from nonketotic diabetes mellitus (group 2). In 11 cats, plasma ketone bodies were detected with the dipstick method (diabetic ketosis, group 3). In 21 cats, plasma ketone bodies and metabolic acidosis were present (DKA, group 4). Plasma β-HB was measured in all cats by an enzymatic method (spectrophotometry). A cut-off value for the diagnosis of DKA was calculated based on the receiver operating characteristic curve. In healthy cats, the β-HB concentration ranged from 0 to 0.1 mmol/l; in cats of group 2, from 0 to 0.9 mmol/l (median: 0.1 mmol/l); in cats of group 3, from 0.6 to 6.8 mmol/l (median: 1.7 mmol/l); and in cats of group 4, from 3.8 to 12.2 mmol/l (median: 7.9 mmol/l). A cut-off value of 2.4 mmol/l revealed 100% sensitivity and 87% specificity to diagnose DKA. Beta-hydroxybutyrate is a useful parameter for the diagnosis of diabetic ketosis and DKA in cats.

description: Malnutrition (undernutrition) remains one of the most serious health problems for older people worldwide. Many factors contribute to malnutrition in older people, including: loss of appetite, polypharmacy, dementia, frailty, poor dentition, swallowing difficulties, social isolation, and poverty. Malnutrition is common in the hospital setting, yet often remains undetected by medical staff. The objective of this review is to compare the validity and reliability of Nutritional Screening Tools (NSTs) for older adults in the hospital setting. We also provide an overview of the various nutritional screening and assessment tools used to identify malnutrition in hospitalised older adults. These include: Subjective Global Assessment (SGA), the Mini Nutritional Assessment (MNA), MNA-short form (MNA-SF), Malnutrition Universal Screening Tool (MUST), Simplified Nutritional Appetite Questionnaire (SNAQ), Geriatric Nutrition Risk Index (GNRI) and anthropometric measurements. The prevalence and outcomes of malnutrition in hospitalised older adults are also addressed.

description: We present a theoretical investigation of the magnetic field dependence of the longitudinal ($T_1$) and transverse ($T_2$) spin relaxation times of conduction band electrons in n-type III-V semiconductors. In particular, we find that the interplay between the Dyakonov-Perel process and an additional spin relaxation channel, which originates from the electron wave vector dependence of the electron $g$-factor, yields a maximal $T_2$ at a finite magnetic field. We compare our results with existing experimental data on n-type GaAs and make specific additional predictions for the magnetic field dependence of electron spin lifetimes.

description: Symmetry shares an entwined history with the structure of physical theory. We propose a consequence of symmetry towards the axiomatic derivation of Hilbert space quantum theory. We introduce the notion of information symmetry (IS) and show that it constraints the state-space structure in any physical theory. To this end, we study the minimal error binary state discrimination problem in the framework of generalized probabilistic theories. A theory is said to satisfy IS if the probability of incorrectly identifying each of two randomly prepared states is same for both the states. It is found that this simple principle rules out several classes of theories while being perfectly compatible with quantum theory.

 Description
In the Mozambican type material (Fig. 14A), six pedunculate individuals arise from a common stolon. The specimen from Djibouti has only two individuals on a common base. A single pedunculate specimen comes from Madagascar.
The largest body reaches 1.5 cm in length on a peduncle of same length and width. The other lobes present either a single body on a narrow peduncle or one body atop a basal part that contains an incompletely developed individual. In all specimens the tunic is corrugated and naked in its anterior part, while some sand and epibionts occur only on the lower tunic. The apical but well-separated siphons do not protrude (Fig. 14A).
The following description is that of the largest individual arising from the upper part of a lobe of the type colony. The tunic is thick, solid but flexible. Removed from the tunic, the body is oval, and the siphons lie opposite a prolongation of the body wall that penetrates a short way into the peduncle.
The body wall is opaque, with an evenly distributed musculature. There is a large oral velum. At its base about 30 long thin tentacles alternate with others that are clearly smaller. The prepharyngeal band curves in a dorsal V where the dorsal tubercle, has a C-shaped slit opening anteriorly. The dorsal lamina is high with a smooth edge. The branchial tissue is thin. There are four round folds on each side, wide and low, carrying uncrowded longitudinal vessels. We counted up to five stigmata in a mesh on the folds. There is an average of two longitudinal vessels between the folds, separated by eight stigmata. The branchial formula is:

description: We investigate the behaviour of two-dimensional quantum field theories with $\mathcal{N}=(0,2)$ supersymmetry under a deformation induced by the `$T\bar{T}$' composite operator. We show that the deforming operator can be defined by a point-splitting regularisation in such a way as to preserve $\mathcal{N}=(0,2)$ supersymmetry. As an example of this construction, we work out the deformation of a free $\mathcal{N}=(0,2)$ theory and compare to that induced by the Noether stress-energy tensor. Finally, we show that the $\mathcal{N}=(0,2)$ supersymmetric deformed action actually possesses $\mathcal{N}=(2,2)$ symmetry, half of which is non-linearly realised.
Global characteristics of the medium produced in ultra-high energy cosmic ray collisions

description: Estimations of some geometrical and bulk parameters are presented for the matter produced in various type collisions with ultra-high energy cosmic ray (UHECR) particles. Results for multiplicity density at midrapidity, decoupling time, and energy density are discussed for small and larger collision systems. Based on the analytic functions suggested previously elsewhere, estimations for a wide set of space-time quantities are obtained for emission region created in various particle collisions at energies of UHECR. The space particle densities at freeze-out are derived also and allow the possibility of novel features for secondary particle production like Bose-Einstein condensation at least for nuclear interactions with UHECR particles. The estimations obtained for global and geometrical parameters indicate the creation of deconfined quark-gluon matter with large enough volume and lifetime even in light nuclear collisions at UHECR energies. These quantitative results can be important for both the future collider experiments at center-of-mass energy frontier and the improvement of the phenomenological models for development of the cosmic ray cascades in ultra-high energy domain.

description: We show how one may sometimes perform singular ambient surgery on the complex locus of a real algebraic curve and obtain what we call a floppy curve. A floppy curve is a certain kind of singular surface in CP(2), more general than the complex locus of a real nodal curve. We derive analogs for floppy curves of known restrictions on real nodal curves. In particular we derive analogs of Fielder's congruence for certain nonsingular curves and Viro's inequalities for nodal curves which generalize those of Arnold and Petrovskii for nonsingular curves. We also obtain a determinant condition for certain curves which are extremal with respect to some of these equalities. One may prohibit certain schemes for real algebraic curves by prohibiting the floppy curves which result from singular ambient surgery. In this way, we give a new proof of Shustin's prohibition of the scheme $1<2\coprod 1<18>>$ for a real algebraic curve of degree eight.

Bracing for Uncertainty: Perceptions of 12 College Art Instructors on the Art Skills, Dispositions, and Teaching of First-Year Art Students

description: This qualitative case study investigates first-year college-level art education in the United States today. Specifically, 12 art instructors from a broad range of postsecondary institutions (including private art institutes, public research universities, public liberal arts colleges, and community colleges) were interviewed to explore perceptions of first-year students’ art skills, dispositions, and teaching. When supplemented by online institutional data, descriptions emerge of the curricular structures and changing teaching environments of the sampled first-year art programs. This study finds that art majors enter college art programs today with different skill sets and dispositions than past students. While digital media offers new options for artmaking, the data suggest it may also influence students’ development of manual, fine-motor, and drawing skills. These art instructors describe first-year students as having shorter attention spans and experiencing greater frustration when learning new skills. Furthermore, the data and literature suggest that more college students today enter with mental health issues (such as anxiety and depression) and learning disabilities. Budgetary cutbacks to K-12 arts programming may have diminished students’ abilities to produce quality portfolios for admission to selective art programs, which may have consequences for enrollment. Enrollments reflect shifting student demographics, such as more international students attending private art colleges. Rising college costs have prompted other changes, such as more students living at home and commuting to save money, or transferring to four-year programs after attending community college, working jobs while attending college, and pursuing career-oriented art majors. First-year art programs are continually adapting to new technical, educational, and cultural challenges through restructured curricula and modified pedagogy targeted to the student demographic served by the institution. In addition to teaching art skills required for subsequent coursework, the participants reported helping first-year students adjust to the college environment in ways that foster personal growth. This study documents changes in first-year art education as a basis for further research. Art educators at all levels benefit from knowledge of how college art instructors and first-year programs are modifying pedagogy and curricula to meet the changing needs of incoming art students.

description: Atomic force microscopy (AFM) with molecule-functionalized tips has emerged as the primary experimental technique for probing the atomic structure of organic molecules on surfaces. Most experiments have been limited to nearly planar aromatic molecules, due to difficulties with interpretation of highly distorted AFM images originating from non-planar molecules. Here we develop a deep learning infrastructure that matches a set of AFM images with a unique descriptor characterizing the molecular configuration, allowing us to predict the molecular structure directly. We apply this methodology to resolve several distinct adsorption configurations of 1S-camphor on Cu(111) based on low-temperature AFM measurements. This approach will open the door to apply high-resolution AFM to a large variety of systems for which routine atomic and chemical structural resolution on the level of individual objects/molecules would be a major breakthrough.

description: A series of new asymmetrical liquid crystal dimers, RnO–S2O–ORn (n = 2–10), linked by an ethylene spacer having carbothiol – COS – and carboxyl – COO – linkages to the core centre of the molecule and bearing different lengths of terminal alkoxy chains were synthesised in order to study the effects of the length of the terminal alkoxy chains on mesomorphic properties. As well as, five symmetrical and asymmetrical dimers linked by butylene spacers bearing different linkages to the core and various terminal chains were also synthesized in order to study the effect of the nature of the spacer and terminal groups. The structures of the synthesised dimers were confirmed by physico-chemical techniques, i.e. FTIR, NMR and mass spectra. Differential scanning calorimetry and polarising optical microscopy verified the liquid crystal behaviour transition temperatures. The isotropic transition temperatures of the dimers RnO–S2O–ORn (n = 2–10) decreased with increasing length of alkoxy chain. Structural effects on the mesomorphic and physical properties were investigated in terms of alteration of carboxylate and thioester groups linking the spacer. The mesomorphic investigation reveals that all the dimers formed an enantiotropic Nematic phase except for dimer HO2SH which is not a liquid crystal.

History

description: This dissertation analyzes the role of various kinds of boycotts and sanctions in the strategies and tactics of those active in the struggle against apartheid in South Africa. What was unprecedented about the efforts of members of the global anti-apartheid movement was that they experimented with so many ways of severing so many forms of interaction with South Africa, and that boycotts ultimately came to be seen as such a central element of their struggle. But it was not inevitable that international boycotts would become indelibly associated with the struggle against apartheid. Calling for boycotts and sanctions was a political choice. In the years before 1959, most leading opponents of apartheid both inside and outside South Africa showed little interest in the idea of international boycotts of South Africa. This dissertation identifies the conjuncture of circumstances that caused this to change, and explains the subsequent shifts in the kinds of boycotts that opponents of apartheid prioritized. It shows that the various advocates of boycotts and sanctions expected them to contribute to ending apartheid by a range of different mechanisms, from bringing about an evolutionary change in white attitudes through promoting the desegregation of sport, to weakening the state’s ability to resist the efforts of the liberation movements to seize power through guerrilla warfare. But though the purpose of anti-apartheid boycotts continued to be contested, boycott had, by 1970, become established as the defining principle of the self-identified anti-apartheid movement.
