description: Gee-Haw Whammy Diddle is a seemingly simple mechanical toy consisting of a wooden stick and a second stick that is made up of a series of notches with a propeller at its end. When the wooden stick is pulled over the notches, the propeller starts to rotate. In spite of its simplicity, physical principles governing the motion of the stick and the propeller are rather complicated and interesting. Here we provide a thorough analysis of the system and parameters influencing the motion. We show that contrary to the results published on this topic so far, neither elliptic motion of the stick nor frequency synchronization is needed for starting the motion of the propeller.

description: General relativistic magnetohydrodynamic (GRMHD) simulations of accretion disks and jets associated with supermassive black holes show variability on a wide range of timescales. On timescales comparable to or longer than the gravitational timescale $t_G=GM/c^3$, variation may be dominated by orbital dynamics of the inhomogeneous accretion flow. Turbulent evolution within the accretion disk is expected on timescales comparable to the orbital period, typically an order of magnitude larger than $t_G$. For Sgr A*, $t_G$ is much shorter than the typical duration of a VLBI experiment, enabling us to study this variability within a single observation. Closure phases, the sum of interferometric visibility phases on a triangle of baselines, are particularly useful for studying this variability. In addition to a changing source structure, variations in observed closure phase can also be due to interstellar scattering, thermal noise, and the changing geometry of projected baselines over time due to Earth rotation. We present a metric that is able to distinguish the latter two from intrinsic or scattering variability. This metric is validated using synthetic observations of GRMHD simulations of Sgr A*. When applied to existing multi-epoch EHT data of Sgr A*, this metric shows that the data are most consistent with source models containing intrinsic variability from source dynamics, interstellar scattering, or a combination of those. The effects of black hole inclination, orientation, spin, and morphology (disk or jet) on the expected closure phase variability are also discussed.

description: The following conversation is a semi-open interview with critical education scholar Noel Gough that aims to get at how critical/social theory, more specifically some aspects of the philosophy of Gilles Deleuze and Felix Guattari can be deployed in science education. Noel Gough’s work has opened the way for other critical scholars in science education to attack fundamental problems and dilemmas related to knowledge, structure, and the control of thought and conduct. Our conversation takes a few twists, but ultimately we ask Noel to elaborate on the role of critical theory in science and education.

description: The ABO3 type charge-ordered antiferromagnetic Nd0.50Ca0.50MnO3 (NCMO) manganite is doped at A-site by 3 % of Ba2+ for Ca2+. The resulting system, Nd0.50Ca0.47Ba0.03MnO3 (NCBMO), is studied for the effects of Ba doping on the magnetic and electronic properties. On application of magnetic field to NCBMO, strongly correlated successive sharp metamagnetic and electronic transitions are observed from antiferromagnetic-insulating to ferromagnetic-metallic state at 2.5 K. The critical magnetic field (Hc) required for metamagnetism is found to reduce drastically from 15 T for undoped NCMO to 3 T for NCBMO. On increasing the temperature, the Hc of NCBMO passes through a minimum. This behavior of Hc of NCBMO contrasts to that of NCMO. The results are discussed in context of A-site cation disorder and size.

description: We construct the Hamiltonian operator of the string field theory for $c=0$ string theory. It describes how strings evolve in the coordinate frame, which is defined by using the geodesic distance on the worldsheet. The Hamiltonian consists of three-string interaction terms and a tadpole term. We show that one can derive the loop amplitudes of $c=0$ string theory from this Hamiltonian.

description: Shear-thinning fluids exhibit surprisingly rich behaviour. One example is the Kaye effect which occurs when a thin stream of a solution of polyisobutylene in Decalin is poured into a dish of the fluid. As pouring proceeds, a small stream of liquid occasionally leaps upward from the heap. This surprising effect, which lasts only a second or so, is named after its first observer A. Kaye, who could offer no explanation for this behaviour. Later, Collyer and Fischer suggested from 250 frames per second cine recordings that the fluid must be highly shear thinning as well as elastic and 'pituitous'. In addition, they concluded that a rigid surface is required to back the reflected liquid stream. While the words bouncing and reflection are associated with non-continuous and elastic effects, we will show here that the Kaye effect is in fact a continuous flow phenomenon. We show that the Kaye effect works for many common fluids, including shampoos and liquid soaps. We reveal its physical mechanism (formation, stability and disruption) through high-speed imaging. The measurements are interpreted with a simple theoretical model including only the shear thinning behaviour of the liquid; elastic properties of the liquid play no role. We show that the Kaye effect can be stable and that it can be directed. We even demonstrate a stable Kaye effect on a thin soap film excluding the necessity of a rigid backing surface.

description: We have measured the diameters of the Cepheid variables delta Cephei (18 nights) and eta Aquilae (11 nights) with the Navy Prototype Optical Interferometer. The primary results of these observations are the mean angular diameters of these Cepheids: 1.520 +/- 0.014 milliseconds of arc (mas) for delta Cep and 1.69 +/- 0.04 mas for eta Aql. We also report limb-darkened diameters for the check stars in this program: for beta Lac, theta(LD) = 1.909 +/- 0.011 mas, and for 12 Aql, theta(LD) = 2.418 +/- 0.010 mas. When combined with radius estimates from period-radius relations in the literature, the Cepheid angular diameters suggest distances slightly smaller than, but still consistent with, the Hipparcos distances. Pulsations are weakly detected at a level of about 1.5 sigma to 2 sigma for both Cepheids.

description: Research in Australia's ethnically diverse rural and regional communities requires an approach that is informed by notions of space, place and culture, and which recognises race as a relational social construct mediated by social and political discourse and context, and prone to change overtime. This review examines how teacher education researchers connect culturally competent research and rural ethics with the view to improving education systems, addressing rural teacher workforce issues, informing the preparation of pre-service teachers, and, most importantly, ensuring that rural students have access to educational opportunities that are engaging and meet their needs. It focuses specifically on researcher positionality on the insider-outsider continuum and how this informs ethical research in diverse rural communities, particularly those in which visible new migrants reside. Peer-reviewed journal articles that discuss how education researchers negotiate working in rural space are examined and considered in relation to discourse about ethics in practice and the insider/outsider continuum. Scholarship reflected in the literature spanned the fields of rural/research ethics, inclusive education, education research methodology and research with new migrants, minority and marginalised groups.

description: Lewy body (LB) formation and degeneration of midbrain dopaminergic neurons are the hall marks of Parkinson’s disease (PD) pathology .α-Synuclein (SNCA) is key macromolecule of these LBs and found to be propagating in a donor-recipient tone from one neuron to another in its misfolded form; facilitating the seeding and spreading of the PD. The donor-recipient scheme is promoted via special population of tiny vesicles of size 50-150 nm specified as exosomes. Other than the disease prospect exosomes are also shown to have role in native functions of neurons like synaptic transmission and cell migration. Further exosomes can be used as delivery vehicles in developing new therapies.Though, exosomes have been reported to have akin business in neuronal physiology but a comprehensive understanding of molecular machinery of exosome secretion is incomplete. We deployed weighted protein correlation network analysis (WPCNA) to fill in the void about molecular components of exosome secretion and membrane trafficking components using proteomic data analysis.
Towards National Consensus: Sustaining an Australian-wide Baseline RDM Training
Creators: name: Chew, Adrian W.
Publisher: name: Zenodo
Year: 2023

description: The Australian Research Data Common (ARDC) Institutional Underpinnings (IU) program has developed a jointly-agreed framework for Research Data Management (RDM). As part of this program, eight universities (i.e., Bond University; Charles Darwin University; Curtin University; Deakin University; Griffith University; University of Canberra; University of New South Wales; and University of Sydney) have developed and pilot tested a Principles Aligned Institutionally-Contextualised (PAI-C) RDM educational/training experience for Higher Degree Research (HDR) candidates. The PAI-C experience is an introductory/baseline RDM training that incorporates the IU RDM framework principles (e.g. storing data safely), and is contextualised based on the respective university's policies, systems and processes. In addition, the PAI-C experience aims to facilitate cross-institutional management of data by raising HDR candidates' awareness of RDM best practices to a common baseline level.

Given that the PAI-C experience is built upon the jointly-agreed IU RDM framework principles, it has the potential to function as an Australian-wide baseline RDM training. However, a baseline is always tentative, and has to respond to changes in the RDM landscape (e.g., changes in legislation, technology, institutional risks/priorities, and researchers' learning needs). As such, the relevance and usefulness of the PAI-C experience may change with time. This BoF will act as a forum to discuss how best, as a sector, we can use the PAI-C experience as a springboard to sustain an Australian-wide baseline RDM training for the long term. This BoF will also allow participants to discuss extension topics/areas that can added to the baseline PAI-C experience.
How to “appreci8” Variant Calling in NGS Data
Creators: name: Sandmann, Sarah
name: Dugas, Martin
Publisher: name: F1000 Research Limited
Year: 2019

description: Background: Calling SNVs and indels in next-generation sequencing (NGS) data is a long-discussed topic. Numerous variant calling approaches are currently available. Despite considerable advances in recent years, detecting low-frequency variants with equally high sensitivity and positive predictive value (PPV) is still challenging. However, for the application of NGS in clinical routine it is essential to rely on valid variant calling results – for high- as well as low-frequency variants.

Methods and results: In close collaboration with medical and biological experts, we developed a variant calling approach called appreci8 - A Pipeline for PREcise variant Calling Integrating 8 tools. Our pipeline combines and filters the output of 8 previously evaluated open-source variant calling tools, using a novel artifact- and polymorphism score. The algorithm aims at reproducing a biologist's manual work when investigating a raw list of calls. Detailed analysis of 7 well-characterized targeted sequencing data sets (678 samples) shows that appreci8 succeeds in calling variants with allelic frequencies at 1% with high sensitivity (0.93 to 1.00) and high PPV (0.65 to 1.00). Appreci8 is able to outperform every individual tool as well as alternative approaches for combining the 8 tools (best alternative: GATK with sensitivity=0.82-0.95 and PPV=0.31-0.94).

Extending the idea of appreci8, we also developed the appreci8R, which is an R-version of our algorithm. The appreci8R provides an additional shiny GUI and checkpoints for re-starting the analysis from intermediate results. Furthermore, all analysis parameters, including the artifact- and polymorphism score, are user-definable. Even the combination and number of input tools can be defined without restriction. Comparing appreci8 and the appreci8R we observe highly comparable performance of both approaches.

Appreci8 is available via Docker (https://hub.docker.com/r/wwuimi/appreci8/), the appreci8R is available via Bioconductor (http://www.bioconductor.org/packages/release/ bioc/html/appreci8R.html).

Discussion: Appreci8 and the appreci8R provide a novel approach for accurate calling of high- as well as low-frequency variants in NGS data.

description: We perform a classical BRST analysis of the symmetries corresponding to a generic $w_N$-algebra. An essential feature of our method is that we write the $w_N$-algebra in a special basis such that the algebra manifestly has a ``nested'' set of subalgebras $v_N^N \subset v_N^{N-1} \subset \dots \subset v_N^2 \equiv w_N$ where the subalgebra $v_N^i\ (i=2, \dots ,N)$ consists of generators of spin $s=\{i,i+1,\dots ,N\}$, respectively. In the new basis the BRST charge can be written as a ``nested'' sum of $N-1$ nilpotent BRST charges. In view of potential applications to (critical and/or non-critical) $W$-string theories we discuss the quantum extension of our results. In particular, we present the quantum BRST-operator for the $W_4$-algebra in the new basis. For both critical and non-critical $W$-strings we apply our results to discuss the relation with minimal models.

Tracking reading in nineteenth-century Melbourne diaries

description: This article sketches some colonial responses to the wider ‘British’ field of Victorian reading by following the reading traces left in the diaries of three middle-class women living in Melbourne from the 1860s to the 1880s, Henrietta Jennings, Thomas Anne Cole and Joyce Sincock. The paper uses the diaries to consider the transcultural nature of Melbourne reading in the late nineteenth-century, and looks at ways to analyse diary records of reading which are always fragmentary. To what extent is it possible to read a list, read the reading, to legitimately interpret nineteenth-century reading practice, religious observance, the place of the popular novel for middle-class women, or the use of the diary in recording or shaping lived, or read, experience?

description: Neutron stars involve extreme physics which is difficult (perhaps impossible) to explore in laboratory experiments. We have to turn to astrophysical observations, and try to extract information from the entire range of the electromagnetic spectrum. In addition, neutron stars may radiate gravitational waves through a range of scenarios. In this brief summary I outline some of the main ideas, focussing on what we do and do not know, and describe the challenges involved in trying to catch these faint whispers from the very edge of physics.

description: We investigate the galactic disk distribution of a sample of planetary nebulae characterised in terms of their mid-infrared spectral features. The total number of galactic disk PNe with 8-13mum spectra is brought up to 74 with the inclusion of 24 new objects, whose spectra we present for the first time. 54 PNe have clearly identified warm dust emission features, and form a sample which we use to construct the distribution of the C/O chemical balance in galactic disk PNe. The dust emission features complement the information on the progenitor masses brought by the gas-phase N/O ratios: PNe with unidentified infrared emission bands have the highest N/O ratios, while PNe with the silicate signature have either very high N enrichment or close to none, and SiC emission features coincide with a range of moderate N-enrichments. We find a trend for a decreasing proportion of O-rich PNe towards the third and fourth galactic quadrants. Two independent distance scales confirmed that the proportion of O-rich PNe decreases from 30+-9% inside the solar circle, to 14+-7% outside. PNe with warm dust are also the youngest. PNe with no warm dust are uniformly distributed in C/O and N/O ratios, and do not appear to be confined to C/O~1. They also have higher 6cm fluxes, as expected from more evolved PNe. We show that the IRAS fluxes are a good representation of the bolometric flux for warm-dust PNe. The requirement F(12um)>0.5Jy should probe a good portion of the galactic disk, and the dominant selection effects are rooted in the PN catalogues.

description: Ordered FePdCu nanoisland arrays were formed by annealing at 600oC, which caused solid state dewetting of [Cu/Fe/Pd] multilayers deposited on self-assembled SiO2 nanospheres with size of 100 nm. A single FePdCu island was formed on the top of each SiO2 nanosphere. The structure of the obtained system was studied by x-ray diffraction (XRD), while its magnetic properties by SQUID magnetometry. Partially ordered L10 alloy appeared in the annealed films, leading to magnetic hardening of the material. The paper presents the influence of the patterning on the system properties. It is shown that templated dewetting is a method providing nanoislands with well controlled sizes and positions. The role of copper admixture in controlling the structural and magnetic properties is also discussed.

Single-Cell RNA Sequencing Uncovers a Large-Oncosome Signature in Medulloblastoma

description: Background: Medulloblastoma (MB) constitutes the most frequent pediatric malignancy of the central nervous system and shows a wide spectrum of clinicopathological features. Despite multiple efforts have been made in defining molecular subgroups of MB, they do not provide an explanation as to why very high-risk tumors consistently emerge from discrete molecular subpopulations that share little overlap in their defining (epi)genotypes.

Methods and results: We performed single-cell RNA sequencing on four samples of a MB mouse model specific of a certain molecular subgroup, namely sonic hedgehog. The analysis conducted on this data, as well as on a published single-cell transcriptome atlas of the developing mouse brain, uncovered a gene expression signature that results from a mutual communication between tumor cells and infiltrating non-tumor cells through extracellular vesicles, named Large-Oncosome-Signature (LOS). Importantly, this signature is also detected in bulk RNA-seq data and RNA microarray profiles of medulloblastoma patients. Through the implementation of a score, we show that LOS provides an independent prognostic marker in two large MB human cohorts.

Discussion: LOS informs about biologically and clinically relevant subtypes and might help to refine the current classification of medulloblastoma.
PAI-C, more than RDM Training: Towards Aligning Institutional RDM Policies, Infrastructure and Understanding
Creators: name: Chew, Adrian W.
Publisher: name: Zenodo
Year: 2023

description: The Australian Research Data Common (ARDC) Institutional Underpinnings (IU) program has developed a jointly-agreed framework for Research Data Management (RDM). As part of this program, eight universities (i.e., Bond University; Charles Darwin University; Curtin University; Deakin University; Griffith University; University of Canberra; University of New South Wales; and University of Sydney) have developed and pilot tested a Principles Aligned Institutionally-Contextualised (PAI-C) RDM educational/training experience for Higher Degree Research (HDR) candidates. The PAI-C experience is an introductory/baseline RDM training that incorporates the IU RDM framework principles (e.g. storing data safely), and is contextualised based on the respective university's policies, systems and processes. In addition, the PAI-C experience aims to facilitate cross-institutional management of data by raising HDR candidates' awareness of RDM best practices to a common baseline level.

This presentation will (1) share the survey and focus group findings from the pilot testing of the PAI-C educational/training experience at the various universities; and (2) more importantly, discuss how through the process of developing and designing the PAI-C educational/training experience, the process itself acted as a way to have RDM conversations with different internal stakeholders at the various universities, which paved the way towards an alignment of institutional RDM policies, infrastructure and understanding.

description: Network models of large-scale electricity systems feature only a limited spatial resolution, either due to lack of data or in order to reduce the complexity of the problem with respect to numerical calculations. In such cases, both the network topology, the load and the generation patterns below a given spatial scale are aggregated into representative nodes. This coarse-graining affects power flows and thus the resulting transmission needs of the system. We derive analytical scaling laws for measures of network transmission capacity and cost in coarse-grained renewable electricity networks. For the cost measure only a very weak scaling with the spatial resolution of the system is found. The analytical results are shown to describe the scaling of the transmission infrastructure measures for a simplified, but data-driven and spatially detailed model of the European electricity system with a high share of fluctuating renewable generation.

description: Traditionally, the definition of a cell type has been performed considering unique cellular shapes or structures, the expression of specific marker proteins or the anatomic location. With the advent of single-cell RNA sequencing, it is possible now to extract information on the expression of thousands of genes in thousands of cells which comprise the tissue of interest, leading to the identification of subpopulations of cells that share a common pattern of gene expression. One of the goals is then to classify each subpopulation according to the corresponding cell type: Here we present the first results of a review of methods employed, until now, for cell type classification. We could delineate, from 16 papers, three major approaches: (i) Empirical methods based on known makers of cell types that require the manual classification by an expert; (ii) Semi-automated methods that rely on known markers but try to combine them with machine learning techniques; (iii) Fully automated methods using machine learning (i.e. neural networks) and collections of published single-cell classified datasets. Our results show that further efforts are necessary in order to classify individual cells on a comprehensive landscape of cell types, taking into account the intrinsic nature of single-cell RNA sequencing data, which is typically noisy and affected by dropout events. Moreover, the great diversity of technologies available for single-cell sequencing poses a challenge in developing a method suitable for different platforms. Eventually, these methods should perform properly in a broad variety of conditions from healthy to diseased.

description: Background: Nipple pain and damage are common in the early postpartum period and are associated with early cessation of breastfeeding and comorbidities such as depression, anxiety, and mastitis. The incidence of nipple vasospasm has not been reported previously. This article describes nipple pain and damage prospectively in first-time mothers and explores the relationship between method of birth and nipple pain and/or damage. Subjects and Methods: A prospective cohort of 360 primiparous women was recruited in Melbourne, Australia, in the interval 2009-2011, and after birth participants were followed up six times. The women completed a questionnaire about breastfeeding practices and problems at each time point. Pain scores were graphically represented using spaghetti plots to display each woman's experience of pain over the 8 weeks of the study. Results: After birth, before they were discharged home from hospital, 79% (250/317) of the women in this study reported nipple pain. Over the 8 weeks of the study 58% (198/336) of women reported nipple damage, and 23% (73/323) reported vasospasm. At 8 weeks postpartum 8% (27/340) of women continued to report nipple damage, and 20% (68/340) were still experiencing nipple pain. Ninety-four percent (320/340) of the women were breastfeeding at the end of the study, and there was no correlation between method of birth and nipple pain and/or damage. Conclusions: Nipple pain is a common problem for new mothers in Australia and often persists for several weeks. Further studies are needed to establish the most effective means of preventing and treating breastfeeding problems in the postnatal period. © Mary Ann Liebert, Inc.

description: We have deposited c-axis oriented thin films of La1.5Dy0.5CaBa2Cu5Oz (La-2125) tetragonal superconductor on LaAlO3 (001) by Pulsed Laser Deposition. These films were irradiated with 200 MeV Ag+15 ions. Atomic Force Microscopy and Elastic Recoil Detection Analysis indicate that the irradiation has created columnar defects along the entire thickness (2000 A) of these films. With ion irradiation up to 1*10^11 ions/cm2, the critical current density (Jc(H)) is found to enhance by almost five folds, which is attributed to the augmented flux pinning by the columnar defects. A further increase in irradiation to 1*10^12 ions/cm2 causes reduction in Jc(H) due to distorted morphology of the film. Our work shows that the enhancement in Jc (H) of the irradiated La-2125 film is comparable to that in irradiated RE-123. Also, as the La-2125 type films have greater chemical stability than RE-123 (RE = rare earth ion), La-2125 type superconductors are potential candidates for applications. Interesting to note that there are partial flux jumps observed to occur symmetrically in the magnetic hysteresis of irradiated La-2125 thin films with enhanced Jc(H).

description: Hubertus J. J. van Dam [Phys. Rev. A 93, 052512, 2016] claims that the one-particle reduced density matrix (1RDM) of an interacting system can be represented by means of a single-determinant wavefunction of fictitious non-interacting particles. van Dam introduced orbitals within a mean-field framework that produce energy levels similar to Hartree-Fock (HF) orbital energies, therefore he also claims that conventional analyses based on Koopmans theorem are possible in 1RDM functional theory (1RDMFT). In this comment, we demonstrate that both claims are unfounded.

description: Sliding along frictional interfaces separating dissimilar elastic materials is qualitatively different from sliding along interfaces separating identical materials due to the existence of an elastodynamic coupling between interfacial slip and normal stress perturbations in the former case. This bimaterial coupling has important implications for the dynamics of frictional interfaces, including their stability and rupture propagation along them. We show that while this bimaterial coupling is a monotonically increasing function of the bimaterial contrast, when it is coupled to interfacial shear stress perturbations through a friction law, various physical quantities exhibit a non-monotonic dependence on the bimaterial contrast. In particular, we show that for a regularized Coulomb friction, the maximal growth rate of unstable interfacial perturbations of homogeneous sliding is a non-monotonic function of the bimaterial contrast, and provide analytic insight into the origin of this non-monotonicity. We further show that for velocity-strengthening rate-and-state friction, the maximal growth rate of unstable interfacial perturbations of homogeneous sliding is also a non-monotonic function of the bimaterial contrast. Results from simulations of dynamic rupture along a bimaterial interface with slip-weakening friction provide evidence that the theoretically predicted non-monotonicity persists in non-steady, transient frictional dynamics.

The Galactic Disk Distribution of Planetary Nebulae with Warm Dust Emission Features: II

description: Can the distribution of warm-dust compositions in IR-bright galactic disk PNe be linked to the underlying stellar population? The PNe with warm dust emission represent a homogeneous population, which is presumably young and minimally affected by a possible dependence of PN lifetime on progenitor mass. The sample in paper I thus allows testing the predictions of single star evolution, through a comparison with synthetic distributions and under the assumption that tip-of-the-AGB and PN statistics are similar. We construct a schematic model for AGB evolution (adapted from Groenewegen & de Jong 1993), whose free-parameters are calibrated with the luminosity function (LF) of C stars in the LMC, the initial-final mass relation, and the range of PN compositions. The observed metallicity gradient and distribution of star forming regions with galactocentric radius (Bronfman et al. 2000) allow us to synthesise the galactic disk PN progenitor population. We find the fraction of O-rich PNe, f(O), is a tight constraint on AGB parameters. For our best model, a minimum PN progenitor mass Mmin=1Msun predicts that about 50% of all young PNe should be O-rich, compared to an observed fraction of 22%; thus Mmin=1.2Msun, at a 2sigma confidence level. By contrast, current AGB models for single stars can account neither for the continuous range of N enrichment (Leisy & Dennefeld 1996), nor for the observation that the majority of very C-rich PNe have Peimbert type I (paper I). f(O) is thus an observable much easier to model. The decrease in f(O) with galactocentric radius, as reported in paper I, is a strong property of the synthetic distribution, independent of Mmin. This trend reflects the sensitivity of the surface temperature of AGB stars and of the core mass at the first thermal pulse to the galactic metallicity gradient.

description: We present an analytic method for calculating spectral densities of empirical covariance matrices for correlated data. In this approach the data is represented as a rectangular random matrix whose columns correspond to sampled states of the system. The method is applicable to a class of random matrices with radial measures including those with heavy (power-law) tails in the probability distribution. As an example we apply it to a multivariate Student distribution.

Imagining Kampung: The Rural and Urban Icons of Malaysia in The Cartoons of Lat

description: In Malaysia’s city/country dialectic, the idea of the kampung or village has a strong hold over a modernising and highly regulated country, as a place of respite and retreat from an official nation-building agenda disseminated and implied through mainstream media. The kampung or village holds a complex position in Malaysian government narratives of national identity. Kampung imagery enjoys ongoing prominence in the oeuvre of Malaysia’s most influential cartoonist Lat, particularly in his autobiographical pictorial novels reflecting his rural upbringing. The kampung itself is constituted via the medium of Lat’s internationally famous cartoons to a global audience for whom the kampung does not have the immediate point of visceral recognition that it has for Malaysians. Our article looks at how Malaysian national identity was constructed through the stereotypical icon of the kampung and its urban counterparts, in Lat’s cartoons. Lat’s cartooning work has received international recognition, and he has been rewarded with the highest honorific title possible for a civilian in Malaysia (the title Datuk was conferred upon him in 1994). Accordingly, we privilege Lat in this paper, over other popular Malaysian cartoonists. In an attempt to outline how Lat and his cartoons played various roles in depicting visions of the kampung, we briefly explore the role of the media in documenting Malaysian national identity, and introduce Lat. We then explore the urban and rural themes found in a selection of Lat’s work, suggesting that through humour his work has had a unifying effect on Malaysians by recording the urban centre as a part of nation-building, the nostalgia of village life, and changing norms in society marked by religious undertones. We suggest that through entertainment and humour his work has had a unifying effect on Malaysians by recording through images of the kampung reflections on shared urban and rural humour.
