description: We study a many-body system of interacting fermionic atoms of two species that are in thermodynamic equilibrium with their condensed heteronuclear bound states (molecules). In order to describe such an equilibrium state, we use a microscopic approach that involves the Bogoliubov model for a weakly interacting Bose gas and approximate formulation of the second quantization method in the presence of bound states of particles elaborated earlier by the authors. This microscopic approach is valid at low temperatures, when the average kinetic energy of all the components in the system is small in comparison with the bound state energy. The coupled equations, which relate the chemical potentials of fermionic components and molecular condensate density, are obtained within the proposed theory. At zero temperature, these equations are analyzed both analytically and numerically, attracting the relevant experimental data. We find the conditions at which a condensate of heteronuclear molecules coexists in equilibrium with degenerate components of a Fermi gas. The ground state energy and single-particle excitation spectrum are found. The boundaries of the applicability of the developed microscopic approach are analyzed.

description: Accretion disc theory is less developed than stellar evolution theory although a similarly mature phenomenological picture is ultimately desired. While the interplay of theory and numerical simulations has amplified community awareness of the role of magnetic fields in angular momentum transport, there remains a long term challenge to incorporate insight gained from simulations back into improving practical models for comparison with observations. Here we emphasize the need to incorporate the role of non-local transport more precisely. To show where large scale transport would fit into the theoretical framework and how it is currently missing, we review why the wonderfully practical approach of Shakura-Sunyaev (1973,SS73) is necessarily a mean field theory, and one which does not include large scale transport. Observations of coronae and jets combined with the interpretation of results even from shearing box simulations of the magnetorotational instability (MRI) suggest that a significant fraction of disc transport is indeed non-local. We show that the Maxwell stresses in saturation are dominated by large scale contributions and the physics of MRI transport is not fully captured by a viscosity. We also clarify the standard physical interpretation of the MRi as it applies to shearing boxes. Computational limitations have so far focused most attention toward local simulations but the next generation of global simulations should help to inform improved mean field theories. Mean field accretion theory and mean field dynamo theory should in fact be unified into a single theory that predicts the time evolution of spectra and luminosity from separate disc, corona, and outflow contributions. Finally, we note that any mean field theory has a finite predictive precision that needs to be quantified when comparing the predictions to observations.

Response of Neisseria gonorrhoeae to iron limitation: alterations in expression of membrane proteins without apparent siderophore production.
Creators: name: The University of North Carolina at Chapel Hill University Libraries
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 1985

description: For acquisition of iron, an essential nutrient, most microorganisms produce siderophores (low-molecular-weight iron-chelating compounds) and membrane proteins to serve as receptors for the iron-siderophore complexes. The gonococcus does not appear to produce a siderophore, since the quantity of siderophore detected by bioassays of culture supernatants from strains F62 and FA19 was never greater than the amount present in the uninoculated medium. Iron limitation of the laboratory strains F62 and FA19 and 12 recent clinical isolates resulted in the expression of several iron-repressible membrane proteins. The expression of proteins in the apparent molecular weight range of 70,000 to 100,000 was strain dependent. All strains expressed 36,000-dalton (36K) and 19.5K proteins. FA19 and F62 were also grown in medium containing iron sources commonly encountered in vivo (i.e., transferrin, lactoferrin, hemoglobin, or hemin). Comparison of growth rates indicates that transferrin and lactoferrin were more readily utilized as iron sources than hemin and hemoglobin were. Expression of the iron-repressible proteins varied depending upon the iron source. Fewer iron-repressible proteins were observed when cells were supplied with transferrin or lactoferrin than when the cultures were grown with either hemin or hemoglobin. The 36K protein was expressed with all four iron sources.
Variation of Neisseria gonorrhoeae protein II among isolates from an outbreak caused by a single gonococcal strain.

description: Gonococci isolated from localized urogenital infections usually possess one or more protein II (P.II) species in the outer membrane, but the structural and antigenic variation of these proteins among different gonococcal strains has made it difficult to determine if specific proteins of the P.II class are associated with particular sites or types of infection. A recent outbreak of gonorrhea in Durham, N.C., was unusual in that over 200 isolates were derived from a single strain, which provided an opportunity to address these questions. The P.II profile of 54 isolates was determined by sodium dodecyl sulfate-polyacrylamide gel electrophoresis of outer membrane proteins. At least seven distinct P.II proteins were seen; no single protein or combination of proteins predominated in the different isolates, and there was no association of P.II profile with site of isolation. Gonococci recovered from the same patient at different times had different P.II profiles, confirming that P.II variation occurred in vivo.

description: In previous studies with hyperimmune rabbit antisera, we found evidence of serologic cross-reactivity among Mycoplasma pneumoniae, Mycoplasma genitalium, and Mycoplasma gallisepticum. Because of certain biologic and morphologic similarities of these species, attempts were made to determine if this cross-reactivity related to the attachment protein (P1) of M. pneumoniae. Monoclonal and monospecific antibodies against P1 were used to probe proteins of the other species by immunoblotting. One of the P1 monoclonal antibodies was reactive with a smaller protein of M. genitalium; rabbit antiserum raised by immunization with P1 excised from a sodium dodecyl sulfate-polyacrylamide gel electrophoresis gel was found to react with a similar-sized protein of M. gallisepticum. These preliminary findings suggest antigenic sharing among the species examined; however, limitations of the methods used are discussed.
Arthropathic group A streptococcal cell walls require specific antibody for activation of human complement by both the classical and alternative pathways.

description: The induction of acute arthritis in rats by a single intraperitoneal injection of group A streptococcal cell wall is associated with the activation of complement. We have therefore investigated the interaction of arthropathic peptidoglycan-polysaccharide complex of streptococcal cell walls and human complement. The incubation of cell wall in normal human serum results in the formation of complexes of cell wall and the C3 and C4 components of complement. Using agammaglobulinemic serum, we have further shown that the activation of complement and formation of complement-cell wall complexes absolutely requires the presence of a small quantity of specific antibody. This antibody is present in normal human immunoglobulin G and is effective as the Fab fragment (alternative pathway). Although antibodies specific for three cell wall epitopes were capable of inducing complement-cell wall complex formation by the classical complement pathway, only anti-A polysaccharide antibody (N-acetyl-D-glucosamine epitope) was effective by the alternative complement pathway. A complement consumption assay showed that anti-cell wall antibody was required not only for complement-cell wall complex formation, but also for activation of complement by streptococcal cell wall in human serum. These studies suggest that a minimal level of anti-cell wall antibody may be required for the induction of arthritis in rats by streptococcal cell wall.

Arthropathic properties of cell wall polymers from normal flora bacteria.
Creators: name: The University of North Carolina at Chapel Hill University Libraries
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 1986

description: Peptidoglycan-polysaccharide (PG-PS) fragments were purified from cell walls of group D streptococci (Streptococcus faecium, strains ATCC 9790 and F-24) with a protocol which minimizes autolytic activity and tested for ability to induce arthritis in rats. PG-PS fragments from cell walls of other normal flora bacteria (Peptostreptococcus productus, and Propionibacterium acnes), group A streptococci, and pseudomurein-PS fragments from cell walls of Methanobacterium formicicum, were similarly purified and tested. Upon intraarticular injection into rat ankles, all PG-PS polymers induced acute inflammation; pseudomurein-PS fragments were approximately five times less active than the PG-PS preparations. After intraperitoneal injection, P. acnes PG-PS induced a minimal acute arthritis, Peptostreptococcus productus PG-PS induced a moderately severe acute joint inflammation followed by a mild chronic arthritis, and both group A and group D streptococcal PG-PS induced severe acute arthritis which evolved into chronic, erosive joint disease; pseudomurein-PS fragments were without effect, consistent with a crucial role for the PG moiety of PG-PS. Chronic arthritis induced by group D streptococcal PG-PS subsided after 60 days, whereas that induced by group A streptococcal PG-PS was still active after 128 days. The arthropathic properties of this modest number of common normal flora bacteria suggest that different PG-PS structures derived from the normal flora have the potential to induce a wide range of responses, from transient acute to chronic erosive joint disease.
Bactericidal effect of normal swine sera on Treponema hyodysenteriae.

Year: 1986

description: Treponema hyodysenteriae was incubated in 20% normal swine sera (NSS) at 37 degrees C for 4 h, and viability was determined by a plate dilution method. NSS was bactericidal for nonpathogenic T. innocens and avirulent T. hyodysenteriae, but not for virulent T. hyodysenteriae isolates. Heat inactivation at 56 degrees C for 30 min, treatment with EDTA or EGTA [ethylene glycol-bis(beta-aminoethyl ether)-N,N-tetraacetic acid], or removal of immunoglobulin M eliminated the bactericidal activity of NSS. However, removal of the alternate complement pathway with 10 mg of bentonite per ml did not remove bactericidal activity of NSS. Incubation of virulent isolates of T. hyodysenteriae in the presence of specific antisera plus NSS resulted in bactericidal activity. These data suggest that complement and natural antibody may be involved in protecting the host from T. innocens or avirulent T. hyodysenteriae and that T. hyodysenteriae antibody plus complement are involved in protecting convalescent pigs from re-exposure to swine dysentery.
Effects of human serum on bacterial competition with neutrophils for molecular oxygen.

description: A dialyzable factor(s) in human serum is known to stimulate gonococcal oxygen consumption. Its effect on other human pathogens was investigated. A 10% serum solution increased peak O2 consumption for Escherichia coli and Staphylococcus aureus to 157% (P less than 0.05) and 199% (P less than 0.02), respectively, of their O2 consumption when suspended in Hanks balanced salt solution, compared with a 356% increase for Neisseria gonorrhoeae with serum. Dialyzed serum lacked stimulatory capacity. Bacteria, serum, and neutrophils are often incubated to evaluate neutrophil bactericidal activity. Samples of 10(8) N. gonorrhoeae, S. aureus, and E. coli turned resazurin colorless (anaerobic conditions, Eh less than -42 mV) after 7.4, 13.3, and 15.1 min, respectively. Because neutrophil formation of reactive oxygen intermediates requires ambient O2, the effect of live bacteria and serum on this process was explored. After 5 min of incubation of 10(8) N. gonorrhoeae or S. aureus in 10% normal or dialyzed serum, 10(5) neutrophils were added. Phorbol myristate acetate was then added to assure neutrophil stimulation, and luminol-dependent luminescence was measured. N. gonorrhoeae and S. aureus incubation in normal serum decreased peak LDL 91.7 and 88.6%, respectively, relative to incubation in dialyzed serum. A sample of 10(8) E. coli totally eliminated LDL. A sample of 10(8) E. coli incubated in Hanks balanced salt solution for 5 min also eliminated phorbol myristate acetate induced neutrophil H2O2 production. LDL inhibition increased in proportion to bacterial concentration and time of incubation and was prevented by inclusion of KCN. Increasing the concentration of neutrophils to 10(8) (1:1 particle-to-cell ratio) only partially reversed LDL inhibition. Re-aeration of the system allowed brief LDL which persisted only if KCN was added. Addition of KCN after bacterial incubation also permitted LDL, arguing against depletion of other factors from the media or accumulation of bacterially derived inhibitory substances. A dynamic competition for O2 occurs between bacteria and neutrophils. Serum stimulation of bacterial O2 utilization may contribute to virulence by increasing bacterial capacity to inhibit neutrophil function.
Foreign Policy of Pakistan: a Critical Approach
Creators: name: Bastos, Maria
Publisher: name: University of Westminster
Year: 2021

description: This thesis examines the interlinking between identity and security in the context of foreign policy in Pakistan. Foreign policy constitutes one of key national policies in Pakistan. Since the country’s inception in 1947, foreign policy has had an unwavering influence on the construction of the state, and of her relations with the international community. The distressed conditions the new state of Pakistan faced in the years after her emergence, led the early leadership to procure security in relations with other international partners, like the US and China. Yet, it was mainly her relations with India that motivated this search for security, which was mostly translated into assembling a fairly large military force. Unsurprisingly, the armed forces, namely the army in association with a militarised intelligence started control the country’s foreign policy decisions. The study and analysis of Pakistan’s foreign policy has followed a conventional approach to International Relations theory. This approach, as the thesis argues, neither permits to investigate how foreign policy is shaped by the interlinking between security and identity, nor allows to contextualise how militarism as an ideology becomes interwoven with security, identity, and masculinity. Thus, this study uses feminist and postcolonial approaches to answer these questions. It focuses on Pakistan’s relations with China, India, and the United States to identify representations of the interlinking between security and identity, as well as representations of militarism. The thesis makes an original and innovative contribution to knowledge in three ways: it applies a feminist and postcolonial approach to the study of Pakistan’s foreign policy, an area that has hitherto been dominated by mainstream IR realist/neo-realist approaches; it puts forward an innovative approach to study the links between state identity and foreign policy, and to ascertain how militarism grows out of this relationship, and it encourages and contributes to new possibilities for study and analysis in the context of South Asian foreign politics and beyond, centred around militarism.
Human immune response to iron-repressible outer membrane proteins of Neisseria meningitidis.

description: Neisseria meningitidis grown under iron-limiting conditions in vitro expresses additional iron-repressible outer membrane proteins (FeRPs). To see which FeRPs were expressed and immunogenic in human infection, we examined purified membranes from four meningococcal disease isolates with Western blotting of patient sera. Convalescent serum from each patient contained immunoglobulin G (IgG) and IgM antibodies against the homologous 70-kilodalton (kDa) FeRP and IgG antibody to the homologous 94-kDa FeRPs. Three other immunoreactive FeRPs were identified in two or more strains. Neither acute-phase sera nor pooled normal human sera contained appreciable levels of these antibodies. Antigenic cross-reactivity among FeRPs was suggested by the observation that the convalescent sera of two patients contained IgG antibodies reactive with the 70- and 94-kDa FeRPs and IgM antibodies reactive with the 70-kDa FeRPs from all four strains. Additionally, rabbit antiserum against the 70-kDa FeRP from one of these disease isolates contained IgG and IgM antibodies that reacted in Western blots with the 70-kDa FeRPs in all four strains. These results demonstrate that meningococcal FeRPs are expressed and immunogenic in vivo and that certain of these proteins are immunologically cross-reactive.

description: We associate to a bimonoidal functor, i.e. a bifunctor which is monoidal in each variable, a nonabelian version of a biextension. We show that such a biextension satisfies additional triviality conditions which make it a bilinear analog of the kind of spans known as butterflies and, conversely, these data determine a bimonoidal functor. We extend this result to $n$-variables, and prove that, in a manner analogous to that of butterflies, these multi-extensions can be composed. This is phrased in terms of a multilinear functor calculus in a bicategory. As an application, we study a bimonoidal category or stack, treating the multiplicative structure as a bimonoidal functor with respect to the additive one. In the context of the multilinear functor calculus, we view the bimonoidal structure as an instance of the general notion of pseudo-monoid. We show that when the structure is ring-like, i.e. the pseudo-monoid is a stack whose fibers are categorical rings, we can recover the classification by the third Mac Lane cohomology of a ring with values in a bimodule.

Additionally, we introduce a novel screening criterion foridentifying candidate twin primes, extending our previous work linkingtwin primes (p and p+2) with the equation 2(p−2) = pu+v, where uniquesolutions for u and v are required. This unified criterion offers a promisingapproach to twin prime identification within a wider range of integers,further advancing research in this mathematical domain
Humoral immune response to Rocky Mountain spotted fever in experimentally infected guinea pigs: immunoprecipitation of lactoperoxidase 125I-labeled proteins and detection of soluble antigens of Rickettsia rickettsii.

description: Rickettsia rickettsii, the etiologic agent of Rocky Mountain spotted fever, purified from infected L-929 cells by density gradient banding were extrinsically radioiodinated with lactoperoxidase. Immunodominant 125I-labeled antigens were identified by radioimmunoprecipitation of detergent-solubilized antigens with protein A-Sepharose and anti-R. rickettsii sera collected 0, 3, 7, 11, 32, and 163 days after infection of guinea pigs. The average fever greater than or equal to 40 degrees C was detected by days 3 and 4 after infection with 6 X 10(7) and 6 X 10(6) PFU, respectively. By microagglutination and complement fixation assays, anti-R. rickettsii antibodies were detected as early as day 3 after infection, with titers increasing markedly between days 7 and 163. Convalescent sera, collected on day 163, from infected guinea pigs were used to identify seven 125I-labeled antigens with apparent molecular sizes of 186,000 (I), 145,000 (II), 49,000 (III), 32,000 (IV), 27,500 (V), 17,500 (VI), and 16,500 (VII) daltons. Differences in antibody reactivity and specificity against the seven antigens were demonstrated with serially obtained sera. Sera from a guinea pig infected with 6 X 10(7) PFU exhibited antibody-antigen interactions with all seven 125I-labeled antigens by day 7, whereas the same antibody activity required 32 days for an animal infected with 6 X 10(6) PFU. Prominent antibody activities toward proteins II and IV were demonstrated both early and late after infection. The fluids obtained from infected L-929 cells contained three soluble antigens which were detected with the 11-, 32-, and 163-day sera by an immunodiffusion assay. The soluble and 125I-labeled antigens of R. rickettsii identified in this study may be important candidates for vaccines against Rocky Mountain spotted fever.

description: Analytical solutions for both a finite assembly and a periodic array of bubbles steadily moving in a Hele-Shaw channel are presented. The particular case of multiple fingers penetrating into the channel and moving jointly with an assembly of bubbles is also analysed. The solutions are given by a conformal mapping from a multiply connected circular domain in an auxiliary complex plane to the fluid region exterior to the bubbles. In all cases the desired mapping is written explicitly in terms of certain special transcendental functions, known as the secondary Schottky-Klein prime functions. Taken together, the solutions reported here represent the complete set of solutions for steady bubbles and fingers in a horizontal Hele-Shaw channel when surface tension is neglected. All previous solutions under these assumptions are particular cases of the general solutions reported here. Other possible applications of the formalism described here are also discussed.

Interaction between Chlamydia spp. and human polymorphonuclear leukocytes in vitro.
Creators: name: The University of North Carolina at Chapel Hill University Libraries
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 1986

description: Chlamydia psittaci and Chlamydia trachomatis elementary bodies (EB) incubated in the presence of complement or specific antibody or both caused chemotaxis of human polymorphonuclear leukocytes (PMN) in vitro. Reticulate bodies and culture supernatants had no effect on these cells. The ability of chlamydiae to enter and survive in PMN under nonopsonizing conditions was investigated by measuring the association of 3H-labeled EB and of inclusion-forming units with these phagocytes. Both assays indicated that C. psittaci as well as C. trachomatis EB are efficiently internalized. The mechanism by which this is accomplished is distinct from classical phagocytosis in that it is not dependent upon the presence of complement or antibody. Furthermore, uptake of at least C. psittaci appeared to be rapid, with no additional increase occurring after 15 min. The majority of cell-associated chlamydiae were rendered acid soluble or noninfectious within 1 h. Subsequently, there was a small but steady loss of infectivity for up to 10 h, which may have been due to the conversion of EB to the noninfectious reticulate-body form of the organism. However, even at 10 h after entry a small percentage of bacteria was still capable of infecting a second target cell. This is noteworthy in that PMN are relatively short-lived cells, and after lysis, intracellular organisms may be free to infect adjacent tissue. Electron microscopic observations were consistent with the data on uptake and persistence. The ability of a small percentage of infecting chlamydiae to maintain infectivity in PMN for at least several hours may enable these organisms subsequently to establish productive infection in permissive host cells.

description: The aim of this paper is to confirm in new concrete examples that the semiclassical entropy of a three-dimensional Lifshitz black hole can be recovered through an anisotropic generalization of the Cardy formula derived from the growth of the number of states of a boundary non-relativistic field theory. The role of the ground state in the bulk is played by the corresponding Lifshitz soliton obtained by a double Wick rotation. In order to achieve this task, we consider a scalar field nonminimally coupled to new massive gravity for which we study different classes of Lifshitz black holes as well as their respective solitons, including new solutions for a dynamical exponent z=3. The masses of the black holes and solitons are computed using the quasilocal formulation of conserved charges recently proposed by Gim, Kim, Kulkarni and Yi and based on the off-shell extension of the ADT formalism. We confirm the anisotropic Cardy formula for each of these examples, providing a stronger base for its general validity. Consistently, the first law of thermodynamics together with a Smarr formula are also verified.

description: A hemorrhage into gut-associated lymphoid tissue developed as early as 3 min after the intravenous injection of group A streptococcal peptidoglycan-polysaccharide polymers into rats. Extravasated erythrocytes were specifically located in the lamina propria and organized lymphoid follicles of the intestines and mesenteric lymph nodes and did not occur in the lungs, kidneys, liver, spleen, adrenal glands, or submandibular and popliteal lymph nodes, as determined by gross and histologic observations and measurement of radiolabeled erythrocytes. Petechial hemorrhage was preferentially located within the intestine to the distal ileum, Peyer's patches, and lymphoid aggregates of the colon. The hemorrhage was transient and occurred in a dose-dependent fashion. It was maximal 5 min after injection and resolved completely by 3 days. A unique feature of this altered vascular permeability was the absence of polymorphonuclear leukocytic infiltration, edema, vasculitis, and tissue necrosis.

description: In gonococci, the nonspecific antimicrobial resistance locus penB is known to be closely linked to loci designated nmp that alter the Mr and antigenicity of the outer membrane porin protein I (P.I). We report that after selection for the linked donor penB locus, occasional recombinants expressed P.I with some epitopes from each parent. These hybrid P.I antigens were stable on subculture and were transformed at a locus closely linked to penB. The hybrid P.I antigens were detected with monoclonal antibodies in both coagglutination and Western blot assays. The alterations of P.I antigenicity may have resulted from recombination between structural genes for P.I that are closely linked to penB.

description: We studied the interaction of African trypanosomes with human complement. Bloodstream forms of Trypanosoma brucei subsp. gambiense isolated from mice activated the alternative pathway of complement during a 30-min incubation in vitro. In human serum, all cells remained intact and motile during this period. C3 was detected on the surface by a direct binding assay with a monoclonal antibody which recognizes C3b and iC3b. C3 deposition could also be detected by this radioimmunoassay when parasites were incubated with purified C3. Such C3 binding was enhanced by factor B, factor D, and magnesium. Surface deposition of factor B was demonstrated both by flow immunofluorescence analysis and binding of radiolabeled factor B. C3 binding and factor B binding were inhibitable by EDTA but not by ethylene glycol-bis(beta-aminoethyl ether)-N,N,N',N' -tetraacetic acid (EGTA). The inhibited binding could be restored by addition of magnesium. No human immunoglobulin G or mouse immunoglobulin was detected on the trypanosome surface. By flow cytometry, neither human C5 nor polymerized C9 was detected on trypanosomes incubated in serum, although this assay was able to detect C5 and C9 on the surface of complement-treated human erythrocytes. Using a radioimmunoassay which measures C5b-9 in serum, we found that there was no generation of SC5b-9 in serum which had been incubated with trypanosomes. We concluded that, although trypanosomes activate the alternative pathway of complement, they are not lysed, because the cascade does not continue beyond the establishment of C3 convertase.

description: Randomized block factorial experiments are widely used in industrial engineering, clinical trials, and social science. Researchers often use a linear model and analysis of covariance to analyze experimental results; however, limited studies have addressed the validity and robustness of the resulting inferences because assumptions for a linear model might not be justified by randomization in randomized block factorial experiments. In this article, we establish a new finite population joint central limit theorem for usual (unadjusted) factorial effect estimators in randomized block 2K factorial experiments. Our theorem is obtained under a randomization-based inference framework, making use of an extension of the vector form of the Wald–Wolfowitz–Hoeffding theorem for a linear rank statistic. It is robust to model misspecification, numbers of blocks, block sizes, and propensity scores across blocks. To improve the estimation and inference efficiency, we propose four covariate adjustment methods. We show that under mild conditions, the resulting covariate-adjusted factorial effect estimators are consistent, jointly asymptotically normal, and generally more efficient than the unadjusted estimator. In addition, we propose Neyman-type conservative estimators for the asymptotic covariances to facilitate valid inferences. Simulation studies and a clinical trial data analysis demonstrate the benefits of the covariate adjustment methods. Supplementary materials for this article are available online.

description: This thesis asks how and why protesters in Japan expressed anger in a series of popular protests over foreign and security policies. Existing studies have underexplored how anger shapes protest dynamics. Anger is closely associated with moral judgment and a form of practice embedded in social contexts. By building upon theories of emotions and frame, this thesis investigates how different injustice frames provide a rationale for political anger. This thesis examines Japan in the post-World War II and early Cold War context (1948-1960), a period which demonstrates highly conflictual dynamics between the government and civil society actors over security issues. To investigate these dynamics, I divide the historical period into three case studies according to the emergence of new political debates, contestation over injustice frames, and social protests. The first case focuses on social protests surrounding Japan's rearmament in the context of the Korean War (1950-1953). The second case looks at popular opposition to the San Francisco Peace Treaty (1952) and the Japan-US Security Treaty (1952). The third case examines the anti-Japan-US security treaty protests in 1959-1960, which were the largest social movements in Japan's history. I employ the method of emotion discourse analysis to uncover the meanings of articulated anger that emerged in the different contexts of the protests. My thesis contends that the protesters expressed their anger to signal how serious the issues were to them, to identify injustices, and to demand action in these popular protests. The expression of anger allowed actors to denaturalise, negotiate, and challenge the dominant national security discourses. This thesis will offer a deeper understanding of the politics of emotions as well as engage in existing debates on the relationship between social movements and foreign policymaking.
