The influence of marijuana expectancy change on drug use in adolescence
Creators: name: Haroon, Maleeha
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2016

description: The current study examined whether change in marijuana outcome expectancies following initial marijuana use mediated the risk conveyed by early marijuana use on future substance use behaviors. Additionally, the study investigated whether the peer context moderated this pathway. The study utilized a longitudinal data set to examine responses from 1,685 adolescents. Results indicated that both initiation of marijuana use and positive change in marijuana expectancies predicted more frequent future marijuana use and that marijuana expectancy change was a significant mediator of the relation between initiation of marijuana use and future marijuana use. Marijuana expectancy change was also a significant mediator of the relation between initial marijuana use and future expectations of using other drugs. The peer context also emerged as a significant mediator of the relation between marijuana use initiation and marijuana expectancy change. Potential explanations and implications of these findings are considered.

description: A honey bee colony functions as an integrated collective, with individuals coordinating their behaviour to adapt and respond to unexpected disturbances. Nest homeostasis is critical for colony function; when ambient temperatures increase, individuals switch to thermoregulatory roles to cool the nest, such as fanning and water collection. While prior work has focused on bees engaged in specific behaviours, less is known about how responses are coordinated at the colony level, and how previous tasks predict behavioural changes during a heat stress. Using BeesBook automated tracking, we follow thousands of individuals during an experimentally induced heat stress, and analyse their behavioural changes from the individual to colony level. We show that heat stress causes an overall increase in activity levels and a spatial reorganization of bees away from the brood area. Using a generalized framework to analyse individual behaviour, we find that individuals differ in their response to heat stress that depends on their prior behaviour and correlates with age. Examining the correlation of behavioural metrics over time suggests that heat stress perturbation does not have a long-lasting effect on an individual’s future behaviour. These results demonstrate how thousands of individuals within a colony change their behaviour to achieve a coordinated response to an environmental disturbance.

description: In this paper, we demonstrate the possibility of generating a non-Abelian Carroll-Field-Jackiw (CFJ) term in the theory of a non-Abelian gauge field coupled to a spin-3/2 field in the presence of the constant axial vector field. Applying two regularization schemes, we prove that this term is finite and ambiguous, particularly vanishing within the 't Hooft-Veltman scheme.

description: The theoretical understanding of emergent phenomena in quantum materials is one of the greatest challenges in condensed matter physics. In contrast to simple materials such as noble metals and semiconductors, macroscopic properties of quantum materials cannot be predicted by the properties of individual electrons. One of the examples of scientific importance is strongly correlated electron system. Neither localized nor itinerant behaviors of electrons in partially filled 3d, 4f, and 5f orbitals give rise to rich physics such as Mott insulators, high-temperature superconductors, and superior thermoelectricity, but hinder quantitative understanding of low-lying excitation spectrum. Here we present a new first-principles approach to strongly correlated solids. It is Q4 based on a combination of the quasiparticle self-consistent GW approximation and the dynamical mean-field theory. The sole input in this method is the projector to the set of correlated orbitals for which all local Feynman graphs are being evaluated. For that purpose, we choose very localized quasiatomic orbitals spanning large energy window, which contains most strongly hybridized bands, as well as upper and lower Hubbard bands. The self-consistency is carried out on the Matsubara axis. This method enables the first-principles study of Mott insulators in both their paramagnetic and antiferromagnetic phases. We illustrate the method on the archetypical charge transfer correlated insulators La2CuO4 and NiO, and obtain spectral properties and magnetic moments in good agreement with experiments.

description: Ferromagnet/heavy metal bilayers represent a central building block for spintronic devices where the magnetization of the ferromagnet can be controlled by spin currents generated in the heavy metal. The efficiency of spin current generation is paramount. Equally important is the efficient transfer of this spin current across the ferromagnet/heavy metal interface. Here, we show theoretically and experimentally that for Ta as heavy metal the interface only partially transmits the spin current while this effect is absent when Pt is used as heavy metal. This is due to magnetic moment reduction at the interface caused by 3d–5d hybridization effects. We show that this effect can be avoided by atomically thin interlayers. On the basis of our theoretical model we conclude that this is a general effect and occurs for all 5d metals with less than half-filled 5d shell.

description: Aircraft collision avoidance maneuvers are important and complex applications. Curved flight
exhibits nontrivial continuous behavior. In combination with the control choices during air traffic
maneuvers, this yields hybrid systems with challenging interactions of discrete and continuous
dynamics. As a case study illustrating the use of a new proof assistant for a logic for nonlinear
hybrid systems, we analyze collision freedom of roundabout maneuvers in air traffic control, where
appropriate curved flight, good timing, and compatible maneuvering are crucial for guaranteeing
safe spatial separation of aircraft throughout their flight. We show that formal verification of hybrid
systems can scale to curved flight maneuvers required in aircraft control applications. We introduce
a fully flyable variant of the roundabout collision avoidance maneuver and verify safety properties
by compositional verification.
Socioeconomic status and overweight: using a "fundamental cause" perspective to examine relationships across time and place

description: Historically, in lower income countries, women with lower socioeconomic status (SES) have had a lower risk of overweight compared to their higher SES counterparts. However, with increasing rates of overweight worldwide, contemporary data suggest that even in some developing countries, lower SES women now have a higher risk of overweight compared to higher SES women. We use data from women (n=556,352) in 41 lower income countries to determine whether the prevalence of overweight has increased disproportionately among low SES women compared to high SES women during the last two decades. We also assess whether the direction of the relationship between SES and overweight has changed for women in these countries. Furthermore, we examine whether there are country-level contextual features that are saliently associated with comparatively faster overweight prevalence gains among low SES women. We find that the relation between SES and overweight has changed direction from positive to inverse in only five countries. However, in approximately 30-50% of the countries, the increases in overweight prevalence over time have been faster in the lowest SES populations compared to the highest SES populations. Country-level economic development was positively associated with faster increases in overweight prevalence among the lower wealth women. The fastest gains in low SES populations were seen in countries that had relatively higher GDP and lower levels of income inequality. We then use longitudinal data from adults in China (1989-2006) to track trajectories of BMI and overweight according to SES. We find larger increases in BMI and overweight over time for the lowest SES women compared to the highest, resulting in the emergence of a socioeconomic disparity in overweight. Opposite findings are seen for men; high SES men (versus low) have higher odds of overweight by the end of the survey. Overall, this study indicates that, predominantly, in lower income countries, low SES women are still less likely to be overweight than high SES women. However, a shift in the burden of overweight also appears to be underway, as the rates of overweight prevalence gains among low SES women are currently outpacing those among high SES women in these contexts.

description: Signalling pathways are conserved across different species, therefore making yeast a model organism to study these via disruption of kinase activity. Yeast has 159 genes that encode protein kinases and phosphatases, and 136 of these have counterparts in humans. Therefore any insight in this model organism could potentially offer indications of mechanisms of action in the human kinome. The study utilises a Prolog-based approach, data from a yeast kinase deletions strains study and publicly available kinase-protein associations. Prolog, a programming language that is well-suited for symbolic reasoning is used to reason over the data and infer compensatory kinase networks. This approach is based on the idea that when a kinase is knocked out, other kinases may compensate for this loss of activity. Background knowledge on kinases targeting proteins is used to guide the analysis. This knowledge is used to infer the potential compensatory interactions between kinases based on the changes in phosphorylation observed in the phosphoproteomics data from the yeast study. The results demonstrate the effectiveness of the Prolog-based approach in analysing complex cell signalling mechanisms in yeast. The inferred compensatory kinase networks provide new insights into the regulation of cell signalling in yeast and may aid in the identification of potential therapeutic targets for modulating signalling pathways in yeast and other organisms.

description: The Raney numbers are a class of combinatorial numbers generalising the Fuss--Catalan numbers. They are indexed by a pair of positive real numbers $(p,r)$ with $p>1$ and $0 < r \le p$, and form the moments of a probability density function. For certain $(p,r)$ the latter has the interpretation as the density of squared singular values for certain random matrix ensembles, and in this context equilibrium problems characterising the Raney densities for $(p,r) = (θ+1,1)$ and $(θ/2+1,1/2)$ have recently been proposed. Using two different techniques --- one based on the Wiener--Hopf method for the solution of integral equations and the other on an analysis of the algebraic equation satisfied by the Green's function --- we establish the validity of the equilibrium problems for general $θ> 0$ and similarly use both methods to identify the equilibrium problem for $(p,r) = (θ/q+1,1/q)$, $θ> 0$ and $q \in \mathbb Z^+$. The Wiener--Hopf method is used to extend the latter to parameters $(p,r) = (θ/q + 1, m+ 1/q)$ for $m$ a non-negative integer, and also to identify the equilibrium problem for a family of densities with moments given by certain binomial coefficients.

description: We consider electromagnetic nonlinear normal modes in cylindrical cavity resonators filled with a nonlinear nondispersive medium. The key feature of the analysis is that exact analytical solutions of the nonlinear field equations are employed to study the mode properties in detail. Based on such a nonperturbative approach, we rigorously prove that the total energy of free nonlinear oscillations in a distributive conservative system, such as that considered in our work, can exactly coincide with the sum of energies of the normal modes of the system. This fact implies that the energy orthogonality property, which has so far been known to take place only for linear oscillations and fields, can also be observed in the nonlinear oscillatory system.

Pragmatic language in autism and fragile X syndrome: links with physiological arousal and anxiety
Creators: name: Klusek, Jessica
Publisher: name: University of North Carolina at Chapel Hill
Year: 2012

description: This dissertation is comprised of three manuscripts focused on delineating pragmatic language profiles in children with autism and fragile X syndrome, and on understanding the potential impact of physiological dysregulation on these profiles. The first manuscript presents a review of the existing literature on physiological arousal in autism and fragile X syndrome, with a focus on the relationship between arousal modulation and social competence. The second two manuscripts present original research: the first consists of a cross-population comparison of pragmatic language in autism and fragile X syndrome; the second extends upon this line of research by examining cardiac arousal as a mechanism that may play a role of social-communicative impairment in these disorders. These three manuscripts address the extent to which pragmatic language deficits overlap in autism and fragile X syndrome, and whether such deficits are linked with dysfunction of the autonomic nervous system. This work has implications for developing syndrome-specific interventions and ultimately may inform biological pathways that may be common to autism and fragile X syndrome.

Model checking and prediction with censored data

description: The class of semiparametric transformation models provides a very general framework for studying the effects of (possibly time-dependent) covariates on survival time and recurrent event times. Although many theoretical and methodological advances have been made for transformation models, the methods for assessing the adequacy of these models have not been formally studied. In the first part of this dissertation, we introduce appropriate residuals for these models and consider the cumulative sums of the residuals. Under the assumed model, the cumulative-sum processes converge weakly to zero-mean Gaussian processes whose distributions can be approximated through Monte Carlo simulation. These results enable one to assess, both visually and numerically, how unusual the observed residual patterns are in reference to their null distributions. The residual patterns can also be used to determine the nature of model misspecification. Extensive simulation studies demonstrate that the proposed methods perform well in practical situations. A colon cancer study is provided for illustration. Attributable fractions are commonly used to measure the impact of risk factors on disease incidence in the population. These static measures can be extended to functions of time when the time to disease occurrence or event time is of interest. In the second part of this dissertation, we deal with nonparametric and semiparametric estimation of attributable fraction functions for cohort studies with potentially censored event time data.The semiparametric models include the familiar proportional hazards model and a broad class of transformation models. The proposed estimators are shown to be consistent, asymptotically normal and asymptotically efficient. Extensive simulation studies demonstrate that the proposed methods perform well in practical situations. A cardiovascular health study is provided. There is a tremendous current interest in using multiple clinical and/or genetic factors to predict progression of disease. To determine which set of factors is most predictive, the predictive accuracy of multiple factors must be quantified. The existing measures are focused on the proportion of variation explained by the factors. These measures are not easily interpreted and have rarely been used in clinical practice. In the third part of this dissertation, we develop measures of predictive accuracy based on the survival curves associated with different sets of predictors. Such measures extend positive and negative predictive values to time-to-event outcomes and multiple factors and have direct clinical relevance. We develop estimators for these measures under flexible censoring mechanisms. The proposed estimators are shown to be consistent and asymptotically normal. Simple Monte Carlo methods are developed to approximate the asymptotic distributions. Simulation studies show that the proposed methods perform well in practical situations. The Mayo primary biliary cirrhosis (PBC) study is provided for illustration.

description: In order to harvest the business potential of device-to-device (D2D) communication, direct communication between devices subscribed to different mobile operators should be supported. This would also support meeting requirements resulting from D2D relevant scenarios, like vehicle-to-vehicle communication. In this paper, we propose to allocate the multi-operator D2D communication over dedicated cellular spectral resources contributed from both operators. Ideally, the operators should negotiate about the amount of spectrum to contribute, without revealing proprietary information to each other and/or to other parties. One possible way to do that is to use the sequence of operators' best responses, i.e., the operators make offers about the amount of spectrum to contribute using a sequential updating procedure until reaching consensus. Besides spectrum allocation, we need a mode selection scheme for the multi-operator D2D users. We use a stochastic geometry framework to capture the impact of mode selection on the distribution of D2D users and assess the performance of the best response iteration algorithm. With the performance metrics considered in the paper, we show that the best response iteration has a unique Nash equilibrium that can be reached from any initial strategy. In general, asymmetric operators would contribute unequal amounts of spectrum for multi-operator D2D communication. Provided that the multi-operator D2D density is not negligible, we show that both operators may experience significant performance gains as compared to the scheme without spectrum sharing.

Designing Chemistry for the Environment: From Processing Fluoropolymers Solutions in Supercritical Carbon Dioxide to New Nonbiopersistent Fluorinated Coating Materials

Year: 2006

description: The solution properties of a fluorinated alkyl methacrylate, poly(1,1,2,2-tetrahydro perfluorooctyl methacrylate) (PFOMA) in carbon dioxide (CO2) were studied by static and dynamic light scattering. The solvent quality of CO2 was found to improve with increasing temperature and CO2 density as exhibited by an increase of the second virial coefficient. Both the hydrodynamic radius expansion factor and the second virial coefficient of PFOMA solution were found to be functions of a single interaction parameter that can be independently changed by either temperature or density variations. Furthermore, we demonstrate that the relationship between two directly measurable quantities, the second virial coefficient and the hydrodynamic expansion ratio, is the same for both temperature-induced and CO2 density-induced variations of solvent quality. The degradation of coating materials that contain long perfluoro chains leads to the release of biopersistent perfluorooctanoic acid (PFOA) into the environment. In order to find environmentally friendly substitutes, a series of fluorinated alkyl methacrylate polymers containing the shorter and non-biopersistant perfluorobutyl group as the fluorinated component of the side chains are synthesized starting from perfuorobutyl iodide. Thermal properties of the polymers were characterized by thermogravimetric analysis (TGA) and differential scanning calorimetry (DSC). Static and dynamic contact angle measurements were used to quantify the surface properties of the thin films for these new non-biopersistant materials (C4 materials). The surface construction, especial the orientation of the fluorinated side chains, were recorded by near edge X-ray fine absorption structure (NEXAFS) experiments. In all, C4 materials displayed the hydrophobic and oleophobic properties with low surfaces tensions and their wetting properties were tuned by varying the "spacer" structures between the backbones and the perfluorinated groups of the side chains.

Intra-familial concordance in lifestyle behaviors and cardiometabolic risk in rapidly modernizing China
Creators: name: Dong, Fei
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2016

description: China has been experiencing rapid changes in lifestyle behaviors and dramatic increases in cardiometabolic disease (CMD) risk factors in both adults and children in the past two decades. Lifestyle behaviors are important contributors to cardiometabolic health. Children share lifestyle behaviors, genes, and home environments with parents, which could underlie clustering in CMD risk in households. However, the extent to which children share behaviors and CMD risk factors with each of their parents has not been studied in a geographically-diverse Chinese population undergoing rapid urbanization. We capitalized on 18-year (1991-2009) longitudinal data from the China Health and Nutrition Survey (>3,000 households with children aged 7-17y), with measured CMD risk factors, diet, physical activity, and sociodemographics. Using random-effects regression, we investigated parent-offspring associations in CMD risk factors (waist-to-height ratio, hemoglobin A1c, blood pressure, and C-reactive protein) and lifestyle behaviors (animal-source foods, away-from-home eating, snacking, screen time, and leisure-time sports). We additionally examined the associations between these behaviors and risk factors in children and their parents, and determined whether household structure (presence of grandparents and presence of siblings in the household) was associated with children’s behaviors or risk factors. We found positive associations in lifestyle behaviors and CMD risk factors between children and their parents. However, the magnitude of parent-offspring associations for behaviors declined over time. We also found faster increases in away-from-home eating and snacking in children than their parents. Compared to children who lived with siblings in the household, only children consumed more animal-source foods, away-from-home foods, snacks, and had higher HbA1c, after adjusting for age, sex, household income, and urbanicity. CMD risk factors in children and their parents were negatively associated with the consumption of fruit and vegetable snacks and positively associated with screen time, with difference in associations between children and their parents for some risk factors. Promoting healthy diet and decreasing screen time are commonly-used intervention strategies to reduce CMD risk. However, given the observed intergenerational differences in behavior changes and behavior-risk associations, generation-specific intervention strategies may be needed. Further, only-children households should specifically be considered for interventions targeting children’s behaviors and CMD risk in this population.

description: We present a proof given by Euler in his paper {\it ``De serierum determinatione seu nova methodus inveniendi terminos generales serierum"} \cite{E189} (E189:``On the determination of series or a new method of finding the general terms of series") for Stirling's formula. Euler's proof uses his theory of difference equations with constant coefficients. This theory outgrew from his earlier considerations on inhomogeneous differential equations with constant coefficients of finite order that he tried to extend to the case of infinite order.

The parent-adolescent relationship, adolescents’ disclosure to parents, and adolescent substance use
Creators: name: Purcell, Susan E.
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2007

description: The purpose of this project was to better understand how qualities of parent-adolescent relationships affect adolescents’ willingness to disclose information to their parents about their lives, a factor linked to adolescents’ risk for substance abuse and other delinquent behaviors (Stattin & Kerr, 2000). Relatively little is known about the pathways linking parenting behaviors and family relationship characteristics, adolescents’ disclosure to parents, and adolescent substance use. Thus, this research project was directed at elucidating specific parent-adolescent relationship qualities predictive of adolescents’ willingness to disclose information to parents, as well as examining whether adolescent disclosure mediates the link between parenting or family environment variables and adolescent substance use. This project utilized data from a short-term prospective study of suburban and rural, predominantly at-risk adolescents and their families, and drew upon both observational and self-reported assessments. Path analysis was used to assess links between family variables, adolescents’ disclosure to parents, and adolescent substance use. Parental involvement and parental consistency predicted higher levels of adolescent disclosure; parental autonomy-granting and adolescent-parent relationships characterized by moderate levels of cohesion and flexibility were marginally predictive of higher adolescent disclosure. Adolescent disclosure mediated the relationship between specific adolescent-parent relationship qualities (parental involvement and cohesion) and prospective risk for adolescent substance use. Longitudinal associations between adolescent disclosure and adolescent substance use outcomes were also explored. Results are discussed in relation to the larger literature regarding the roles of adolescent-parent relationship quality and parental behavior management practices in the prevention of delinquency outcomes. The strengths, limitations, and future directions for this research are also addressed.

description: Die verschiedenen Aufgabenfelder der Heilpädagogischen Früherziehung zeigen, dass die Kom-munikation fester Bestandteil des Berufes ist. Doch welche kommunikativen Fertigkeiten werden dabei angewendet und wie werden diese erworben? Um diese Fragen zu beantworten, werden drei episodische Interviews mit Fachpersonen aus der Früherziehung geführt. Die inhaltlich strukturierende qualitative Inhaltsanalyse erfolgt mit der Software f4 analyse. Die Ergebnisse zeigen, dass Fachpersonen aus der Heilpädagogischen Früherziehung einzelne kommunikative Fertigkeiten bewusst einsetzen, um damit ein Ziel zu erreichen. Der Erwerb wird durch Berufs- und Lebenserfahrung, Aus- und Weiterbildungen, sowie dem Austausch unter Berufskolleginnen erweitert. Auf Grund der Ergebnisse kann eine Empfehlung zur Förderung der kommunikativen Fertigkeiten in der Heilpädagogischen Früherziehung formuliert werden.
Formal Verification by Symbolic Evaluation of Partially-Ordered Trajectories

description: Symbolic trajectory evaluation provides a means to formally verify properties of a sequential system by a modified form of symbolic simulation. The desired system properties are expressed in a notation combining Boolean expressions and the temporal logic 'next-time' operator. In its simplest form, each property is expressed as an assertion [A⇒C], where the antecedent A  expresses some assumed conditions on the system state over a bounded time period, and the consequent C expresses conditions that should result. A generalization allows simple invariants to be established and proven automatically.
The verifier operates on system models in which the state space is ordered by 'information content'. By suitable restrictions to the specification notation, we guarantee that for every trajectory formula, there is a unique weakest state trajectory that satisfies it. Therefore, we can verify an assertion [A⇒C] by simulating the system over the weakest trajectory forA and testing adherence toC. Also, establishing invariants correspond to simple fixed point calculations.
This paper presents the general theory underlying symbolic trajectory evaluation. It also illustrates the application of the theory to the taks of verifying switch-level circuits as well as more abstract implementations.
Euler and the Legendre Polynomials

description: In this note we will present how Euler's investigations on various different subjects lead to certain properties of the Legendre polynomials. More precisely, we will show that the generating function and the difference equation for the Legendre polynomials was already written down by Euler in at least two different papers. Furthermore, we will demonstrate that some familiar expressions for the Legendre polynomials are corollaries of the before-mentioned works. Finally, we will show that Euler's ideas on continued fractions lead to an integral representation for the Legendre polynomials that seems to be less generally known.

title: Shadow banking and corporate finance
Creators: name: Peng, Hao
Publisher: name: University of Glasgow
Year: 2020
Subjects: subject: Shadow banking, corporate finance, cash holding, earnings management.

description: This thesis examines how shadow banking activities affect firms’ behaviors. We focus on two important representatives of shadow banking activities: wealth management products issued by commercial banks and finance companies affiliated in business groups in China. By observing how corporates’ cash holding policies, investment decisions and financing choices response to dynamic changes in the shadow banking activities through three empirical studies, we find that the wide spread of shadow banking activities in China plays an important role in explaining corporate behaviors.

description: We apply the Jeffrey-Kirwan method to compute the multiple integrals for the $BCD$ type Nekrasov partition functions of four dimensional $\mathcal{N}=2$ supersymmetric gauge theories. We construct a graphical distinction rule to determine which poles are surrounded by their integration cycles. We compute the instanton correction of the "$Sp(0)$" pure super-Yang-Mills theory and find that $Z^{Sp(0)}_{k}=(-1)^{k}(2^{k}k!\varepsilon_{1}^{k}\varepsilon_{2}^{k})^{-1}$ for $k\le 8$, which resembles the formula $Z^{U(1)}_{k}=(k!\varepsilon_{1}^{k}\varepsilon_{2}^{k})^{-1}$ for the pure super-Yang-Mills theory with gauge group $U(1)$.

description: Molecular machines enable external control of structural and dynamic phenomena at the atomic level. To efficiently transfer their tunable properties into designated functionalities, a detailed understanding of the impact of molecular embedding is needed. In particular, a comprehensive insight is fundamental to design hierarchical multifunctional systems that are inspired by biological cells. Here, we applied an on-the-fly trained force field to perform atomistic simulations of a systematically modified rotaxane functionalized metal-organic framework. Our atomistic studies reveal a symmetric and asymmetric interplay of the mechanically bonded rings (MBRs) within the framework depending on the local environment. As a result, their translational motion is modulated ranging from fast oscillatory behavior to cooperative and potentially directed shuttling. The derived picture of competitive interactions, which influence the operation mechanism of the MBRs embedded in these soft porous materials, promotes the development of responsive functional materials, which is a key step toward intelligent matter.

Indonesian Bildungsroman in Pramoedya A. Toer's Buru Quartet
Creators: name: Sunardi, Dono
Publisher: name: Zenodo
Year: 2011

description: This thesis discusses the problem of why Indonesian nationalism turns to be as oppressive as the Dutch colonialism it replaced. Indonesia, a postcolonial state that declared its independence in the aftermath of World War II, is, following Benedict Anderson, an imagined community born out of the futuristic imagination or desire to create a just, democratic society. In answering that problem, this thesis starts from the hypothesis that that story of Indonesian nationalism can actually be viewed as bildungsroman. Indonesian nationalism should be seen as the story of maturing and of education. Dynamicity and hybridity are two crucial aspects in understanding Indonesian nationalism as a bildungsroman. Unfortunately, both the perspective of seeing Indonesian nationalism as a bildungsroman and the two crucial aspects mentioned above have so far been denied by the postcolonial state regimes in Indonesia. Pramoedya Ananta Toer’s Buru Quartet lends us a great insight to rediscover the bildungsroman of Indonesia. The Quartet itself is the bildungsroman of Minke, an educated and a hybrid, who we can see as the metonymy, in Lacanian sense, for the story of Indonesia. Finding the dynamicity and hybridity in Minke means rediscovering the dynamic and hybrid nature of Indonesian nationalism.
