public drinking
congregation

description: On weekend nights, youngsters would often congregate along pedestrian bridges and public sidewalks in Clarke Quay and Robertson Quay to drink before moving into the surrounding clubs for a night of dancing. Similarly, foreign workers would gather in public fields or in the void decks of Housing Development Block (HDB) flats on weekends to drink and unwind. Unsurprisingly, residents living around these drinking ‘hotspots’ frequently expressed dismay over the nuisances created by large groups of drinkers, such as vomiting, rowdiness, and sometimes even violence. This case explores whether policy-makers should clamp down on public drinking in these hotspots, and if so, how they could go about doing so. The case then provides an overview of a new law restricting public drinking that was passed in 2015, and examines reactions to this law.

Put Her In Coach: Female Sports Journalists’ Role in Women’s Athletic Coverage in the Media
Creators: name: Cummings, Jamie
Publisher: name: The University of North Carolina at Chapel Hill University Libraries

description: The Chicago newspaper’s
infamous Twitter headline
read “Wife of Bears’ lineman
wins a bronze medal today in
Rio Olympics.” Corey Cogdell-Unrein
had just won her second Olympic
medal in trap shooting only to
have her name and success attributed
to her spouse’s athletic career.
Unfortunately, microaggressions
such as this one are not uncommon
in the media’s coverage of women’s
sports. Moreover, the coverage itself
is problematic, as it is nearly
non-existent compared to the attention
men’s sports receive. Society
has arbitrarily placed sport within
the domain of men. The debate is
often framed by the claim that insufficient
interest in female athletics
makes them unprofitable. The real
question is whether or not the reason
behind the lack of interest is the lack of coverage. Evidence suggests
the market of female audiences is
growing all the time. The solution
to the disparities faced in coverage
and microaggressions may rest with
female journalists who are more
likely to quote and report on women
than men. In a vicious cycle, gender
hiring practices in sports journalism
are unequitable, perpetuating
the media’s problematic limited
attention to female sport. Media organizations
must support women in
editorial and leadership roles if they
wish to avoid sexist culture and the
estrangement of female fanatics.

Frontiers. Privatize, Democratize, Decolonize: Ocean Epistemologies in the 21st Century
Creators: name: Havice, Elizabeth
Publisher: name: Routledge
Year: 2021

description: Knowledge, as well as knowledge gaps about the oceans, shape the ways that humans govern these spaces, which are often beyond direct human observation.  Like other frontiers in Western historiography, the ocean is susceptible to imperialism, anthropocentrism, and resource-driven global capitalism. However, it is also a site of possible alternatives to these dominant approaches because it is relatively ‘undergoverned’ in comparison with land, and its material features can present challenges to enclosure and commodification. What then, is the role that knowledge plays in influencing ongoing tensions among extraction, conservation and intergenerational justice in the oceans? We offer three epistemological lenses that each focus, disperse and enrich understanding of the knowledges pertaining to ocean spaces and governance. First, we examine the role of proprietary data in shaping contemporary resource extraction and accompanying regulatory and conservation debates in the deep seabed. Second, we consider emerging new data technologies and accompanying visualization techniques that aim to democratize oceans governance by making knowledge about oceans and processes on and in them widely available. Finally, we consider decolonized, anti-anthropocentric knowledges about ocean spaces, ‘nations’ and accompanying relationships and responsibilities. In doing so, we identify a disparate array of knowledges -- that we conceptualize as an epistemological frontier -- as central to the future of oceans presently beyond full incorporation into capitalist circuits, but increasingly within their sights.

Central Provident Fund (CPF)
pension system
income inequality
ageing population
retirement

description: Singapore’s Central Provident Fund (CPF) had been widely acknowledged to be a well-designed pension system. Established as a mandatory employee savings scheme, it avoided the fiscal problems that plagued other pension systems faced with ageing populations, and also helped to lift Singapore’s home ownership rate to one of the highest in the world. However, against a backdrop of increasing life expectancy, high income inequality and the rising cost of living, many Singaporeans began to express concerns about various facets of the CPF. These ranged from a lack of flexibility over the use and withdrawal of their CPF monies, to fears of insufficient CPF savings for retirement, to the increasing complexity of the CPF system.

This case first provides an overview of the CPF system and its key objectives, then invites its readers to examine the concerns voiced by the public, as well as assess the possible improvements that could be made to existing CPF policies.
A Discursive Examination of Gendered Whiteness: White womanhood, white supremacy and the colonial site of the university
Creators: name: Davis, Haley
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2020

description: This thesis examines the role of ruling class white womanhood at historically white universities in the South. I analyze how this identity is instrumental in maintaining political, economic, and social structures of patriarchal white supremacy at the institution. To interrogate this subject, I ask: how does owning class white womanhood serve patriarchal white supremacist state institutional power at historically white universities in the South? I ground this question’s importance in historical geographies of white women spreading white supremacist violence through the realm of education. I look at histories of imperial settler colonial white women schoolteachers, the United Daughter of the Confederacy’s (UDC) campaigns in schools, pro-segregationist white woman who fought to keep schools segregated, the weaponization of white womanhood’s “sanctity” in the Wilmington Massacre of 1898, and a short history of the university’s foundation and reliance on white supremacy for its sustenance and continued existence. I focus my research on ex-chancellor Carol Folt who served as a university leader from 2013-2019 as a case study. I do a discursive analysis of chancellor Carol Folt’s messages and speeches to the public found in archival data. Analysis of Folt’s language demonstrates persisting key characteristics of white womanhood’s violence throughout history in education. Two key ways in which such violence is enacted is through: (1) saviorisim in university diversity initiatives without changing structurally racist conditions of the institution, and (2) manipulation of loving and caring language centered around safety that evades responsibility to making anti-racist structural change. This analysis offers insight into the violent and oppressive ways white women continue to enact and uphold structural and interpersonal white supremacy through the realm of education.

description: Halogen bonding to phosphorus atoms remains uncommon, with relatively few examples reported in the literature. In part 1 of the thesis, the preparation and investigation of the cocrystal (dicyclohexylphenylphosphine)(1,6-diiodoperfluorohexane) by X-ray crystallography and solid-state multinuclear magnetic resonance spectroscopy is described. The crystal structure features two crystallographically unique C-I···P halogen bonds (dI···P = 3.090(5) Å, 3.264(5) Å) and crystallographic disorder of one of the 1,6-diiodoperfluorohexane molecules. The first of these is the shortest and most linear I···P halogen bond reported to date. 13C, 19F, and 31P magic-angle spinning solid-state NMR spectra are reported. A 31P chemical shift change of -7.0 ppm in the cocrystal relative to pure dicyclohexylphenylphosphine, consistent with halogen bond formation, is noted. This work establishes iodoperfluoroalkanes as viable halogen bond donors when paired with phosphorus acceptors, and also shows that dicyclohexylphenylphosphine can act as a practical halogen bond acceptor. In part 2 of the thesis, computational work was done on nuclides of atoms which engage in the strongest halogen bonds (iodine, bromine, chlorine) that are all quadrupolar (spin I > ½). Previous group work reported extensive experimental NMR and NQR data relating 35/37Cl, 79/81Br, and 127I quadrupolar coupling information to local molecular structure in halogen bonded systems. Here, we make use of a new parameter, the valence p-orbital population anisotropy (VPPA), reported by Rinald and Wu, to increase our understanding of the origins of the electric field gradients (EFG) in halogen-bonded systems. Computations on model and real halogen-bonded cocrystalline systems using standard hybrid DFT methods are used to generate p-orbital populations and to compute the VPPA. We discuss the utility of the VPPA, and hence the EFG, as a tool to assess the ability of particular donors to engage in halogen bonds.

For some other algorithms, which are known to have a unique invariant measure absolutely continuous with respect to Lebesgue measure, the invariant domain found by this method seems to have a fractal boundary, and it is unclear that it is of positive measure.

description: A recipe to control the first wave of COVID-19: more or less democracy? Abstract Purpose – This research aims to study some national government success factors at controlling the first wave of COVID-19. The author placed special attention on democracy-related factors. Design/methodology/approach – A sample of 156 countries were studied during the first half of 2020 and their government effectiveness was analyzed regarding six dependent variables, namely, the government’s daily average of stringency index, the outbreak response time, the daily average of cases and deaths per million, the daily average of tests per thousand and the mortality rate. Findings – The study finds that countries with the highest democracy indexes applied the softest social constraints measured by the daily average stringency index. These countries suffered a more severe pandemic impact confirmed by the highest daily averages of cases and deaths per million and the highest mortality rate. Similarly, these countries exhibited the shortest outbreak response time and the most extensive daily average tests per thousand. Research limitations/implications – The limitations of this study include lack of universal consensus for the dependent variables’ definitions, inconsistencies in how countries record COVID-19 deaths, differences in testing efforts, variances on health services, unreliable data from less democratic countries and so on. Originality/value – To the best of the author’s knowledge, no previous research paper has studied the explanatory power of the author selected government success factors at controlling the first wave of COVID-19, which constitutes this study’s original contribution.
The Adaptation Experiences of Chinese PhD Students in the UK

description: Chinese students make considerable contributions to Western countries both financially and academically. The increasing number of Chinese doctoral students in the UK highlights the importance of understanding their experience when faced with new and unfamiliar British social and educational contexts. Although research on the adaptation experiences of Chinese undergraduate and taught postgraduate students is relatively well-established, studies focused specifically on international Chinese doctoral students are still very rare. This study therefore aims to explore the adaptation experiences of Chinese PhD students in UK universities. Using Bourdieu’s concepts of habitus, field and capitals as its theoretical base, the study begins by examining the challenging aspects of Chinese doctoral students’ experiences resulting from the mismatch in approach and norms between the students’ field of origin in China, and their new field in the UK. It also examines the coping strategies employed by individuals in order to adapt their habitus in ways to better ‘fit into’ British contexts. Based on qualitative interviews with staff and Chinese doctoral students at four different English universities, supplemented with analysis of institutional documentation, this study concludes by arguing that there was ultimately more similarity than difference between the students in terms of experiences and adaptations. These students often encountered challenges in academic, sociocultural and well-being realms. The prevailing response among these students was to make fairly superficial adaptations to the academic demands of their programme, while leaving the core of their habitus and identity intact; thus operating a ‘cleft habitus’ and ‘playing the academic game’ in a more strategic way. Only a minority of the students made successful and more genuine adaptations both academically and socioculturally – thus experiencing a clearer shift in their habitus and achieving, in Bourdieu’s terms, ‘practical mastery’. The study also highlights some practical recommendations for HE practitioners, and reas ripe for further research.
Psychosocial Stressors and Cardiovascular Disease Risk Factors in Young African American Women: A Systematic Literature Review
Creators: name: Harris, Latesha
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2020

description: Introduction: African American women experience a unique multitude of psychosocial stressors, including racism, discrimination, poverty, neighborhood stress, anxiety, and depression. The impact of these stressors on cardiovascular disease (CVD) risk in women during early adulthood is limited. This review aims to summarize and synthesize the recent literature on psychosocial stress and cardiovascular disease risk factors in young African American women. 
Methods: We conducted a comprehensive search of the literature in PubMed, APA PsycINFO, and CINAHL. We systematically reviewed the literature for studies examining psychosocial stress and CVD risk factors in African American women age 19-24 years. Eligible studies measured at least one psychosocial stress exposure, a CVD risk factor, and included young adult African American women (age 19-24) or reported sex-stratified analyses.
Results: We identified nine studies that met our inclusion criteria: six cross-sectional and three cohort studies. Of the nine studies, eight reported that stress (i.e., perceived stress, racial discrimination, internalized racism, depression) is related to body mass index and blood pressure. Overall, the majority of studies rated excellent; the remainder were good and fair.
Conclusion: Findings from this review suggest limited research on the association between stress and CVD risk among African American women in early adulthood. While the quality of the majority of studies was “excellent”, the majority were conducted among college students or had a small sample size. Included studies suggest that exposure to stress and adversity in early life are related to increased CVD in early adulthood in African American women.

description: As the 7 December 2007 equinox of Uranus approached, ring and atmosphere observers produced a substantial collection of observations using the 10-m Keck telescope and the Hubble Space Telescope. Those spanning the period from 7 June 2007 through 9 September 2007 we used to identify and track cloud features, determine atmospheric motions, characterize cloud morphology and dynamics, and define changes in atmospheric band structure. We confirmed the existence of the suspected northern hemisphere prograde jet, locating its peak near 58 N, and extended wind speed measurements to 73 N. For 28 cloud features we obtained extremely high wind-speed accuracy through extended tracking times. The new results confirm a small N-S asymmetry in the zonal wind profile, and the lack of any change in the southern hemisphere between 1986 (near solstice) and 2007 (near equinox) suggests that the asymmetry may be permanent rather than seasonally reversing. In the 2007 images we found two prominent groups of discrete cloud features with very long lifetimes. The one near 30 S has departed from its previous oscillatory motion and started a significant northward drift, accompanied by substantial morphological changes. The complex of features near 30 N remained at a nearly fixed latitude, while exhibiting some characteristics of a dark spot accompanied by bright companion features. Smaller and less stable features were used to track cloud motions at other latitudes, some of which lasted over many planet rotations, though many could not be tracked beyond a single transit. A bright band has developed near 45 N, while the bright band near 45 S has begun to decline, both events in agreement with the idea that the asymmetric band structure of Uranus is a delayed response to solar forcing, but with a surprisingly short delay of only a few years.

Theory and modelling of quantum transport in molecular-scale structures
Creators: name: Almeshal, Abdelkareem
Publisher: name: Lancaster University
Year: 2020

description: The theoretical work carried out in this thesis presents the electrical properties of two different types of two terminal molecular junctions: one dealing with gold electrodes which form gold |molecule| gold structures and the other with a graphene sheet and gold electrodes forming gold |molecule| graphene junctions. The theoretical tools employed are firstly, density functional theory (DFT). Chapter 2 presents an introduction to the theoretical concept of DFT and the implementation used in this work, namely the SIESTA code. The second tool is the quantum transport code GOLLUM. To introduce this technique in Chapter 3, I present solutions of Green’s functions for infinite and semi-infinite chains and the transmission coefficient equation which forms the theoretical basis of this code. The main results of this thesis are as follows: The first topic I identify Fano resonances in the transport properties of carbine-metal- amides and demonstrate that their energetic location and magnitude can be controlled by varying the connectivity of the core to external electrodes and by rotating the pendant moiety connected to the current-carrying core. The Fano resonances can be suppressed by rotating the pendant group and increasing the linkages to electrodes. Secondly, I compute the transmission coefficient, electrical conductance and thermoelectric properties of structures formed from terthiophene with tetracyanoethylene and terthiophene with dinitrotoluene. A theoretical investigation into the Seebeck coefficient in stacked molecular junctions is performed using a first principles quantum transport method. I show that the quantum interference produces Fano resonance in the gap between the HOMO and LUMO and the stacking geometry can control the position of this quantum interference feature. The shifting of this resonance enhances the thermopower as expected when the junction is tuned through a node in the transmission function. I also found that supramolecular interactions between two molecules changed the sign of thermopower. Finally, I look at an experimental example of a molecular switch formed in a gold/molecule/graphene vertical junction. Here the charge state of a ferrocene molecule is controlled by the application of an electrochemical bias. I present the electrical conductance and IV characteristics for a molecule (6-(ferrocenyl) hexanethiol) attached to gold lead and graphene sheet and explain how the behaviour seen in the experiment arises from the electrostatic repulsion of the molecule with the graphene electrode.

description: In the last years, chiral effective field theory has been successfully developed for and applied to systems with few nucleons. Here, I present a new approach for ab initio calculations of nuclei that combines these precise and systematic forces with Monte Carlo simulation techniques that allow for exact solutions of the nuclear A-body problem. A short introduction of this method is given and a few assorted results concerning the spectrum and structure of 12C and 16O are presented. The framework further allows one to study the properties of nuclei in worlds that have fundamental parameters different from the ones in Nature. This allows for a physics test of the anthropic principle by addressing the question how strongly the generation of the life-relevant elements depends on the light quark masses and the electromagnetic fine structure constant.

The controlling signals are GF(2) expressions possibly including Boolean expressions. The method does not require operating with complex-valued matrices. The method may be used to verify the functionality and to check for possible minimization of a given quantum computing circuit using target lines. The method does not apply for a whole circuit if there are interactions among target lines. In this case the method applies for the independent subcircuits.

description: Optimal mechanisms have been provided in quite general multi-item settings, as long as each bidder's type distribution is given explicitly by listing every type in the support along with its associated probability. In the implicit setting, e.g. when the bidders have additive valuations with independent and/or continuous values for the items, these results do not apply, and it was recently shown that exact revenue optimization is intractable, even when there is only one bidder. Even for item distributions with special structure, optimal mechanisms have been surprisingly rare and the problem is challenging even in the two-item case. In this paper, we provide a framework for designing optimal mechanisms using optimal transport theory and duality theory. We instantiate our framework to obtain conditions under which only pricing the grand bundle is optimal in multi-item settings (complementing the work of [Manelli and Vincent 2006], as well as to characterize optimal two-item mechanisms. We use our results to derive closed-form descriptions of the optimal mechanism in several two-item settings, exhibiting also a setting where a continuum of lotteries is necessary for revenue optimization but a closed-form representation of the mechanism can still be found efficiently using our framework.

Encountering the Worlds of Slow Cinema: Spectatorship, Duration, and Nostalgia
Creators: name: Martin, Josh
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2020

description: This thesis addresses the international mode of contemporary slow cinema. Comprised of films notable for long takes, minimalist narratives, and a careful sense of attention to quotidian daily activities, this mode has received increased scholarly attention in recent years. Contrary to existing scholarship, this thesis proposes a malleable relationship between slow aesthetics and popular modes. More specifically, this thesis also introduces the concept of the "hangout film," a popular mode in which duration, nostalgia, and the presentation of daily activities are essential to its style. Through analysis of films by Tsai Ming-liang, Kelly Reichardt, and Quentin Tarantino, this thesis argues for an expanded understanding of cinematic slowness and its presence in contemporary films.

Year: 2022

description: Abstract: Searches for electromagnetic transmissions from extraterrestrial agents (primarily in the optical and radio wavelengths) comprise the most well-developed sub-field within the SETI literature, both in theory and in observation. While the technosignature field has diversified in recent years, the rationale for radio and optical SETI remains extremely convincing, and recent projects have made huge strides in covering new parameter space. In this talk, I will cover the history of radio and optical SETI, the pros and cons of these techniques, current and near-future campaigns and instruments, and why transmission-based SETI is a necessary cornerstone of a well-rounded technosignature portfolio.

The Dynamics of Discs in Young Stellar Systems

description: Star formation produces single, binary, and higher order young stellar systems that can host protostellar discs, as evidenced by recent observations of embedded disc structure. In this thesis, I present numerical simulations of circumsingle and circumbinary discs in this context. At early times, embedded discs are likely massive and potentially gravitationally-unstable. Disc temperature (among other parameters) controls the stability of discs - cooling discs faster than they can be heated can result in disc fragmentation, but otherwise can produce long-lasting spiral structure. I study circumsingle discs in both regimes. I investigate the critical cooling timescale convergence using the established βc parameterisation, finding convergence only for constant linear artificial viscosity with resolution. There is no physical convergence for various artificial viscosity settings or modified disc models that boost resolution. Suitable parameter choices may produce convergence but at significant computational cost (i.e. high resolutions), contradicting the appeal of βc. I model fragmentation-stable, self-gravitating discs that grow from low-mass, making comparisons with observations. I find these discs agree with standard disc models and the observed disc structure of Elias 2-27, with no dependency on growth rate. This suggests discs naturally approach a quasi-steady state of marginal stability. However, I expect disc evolution to diverge for growth rates exceeding the local transport rate (i.e. fragmentation-unstable discs). Like self-gravitating discs, prograde circumbinary discs are also perturbed, here from resonances between the binary and disc orbits. Waves are launched in the disc allowing the binary to transfer its angular momentum to the disc, acting against the viscous torque. I study this disc-binary interaction by varying disc thickness, viscosity and equation of state, showing how the boundary between binary orbit expansion and contraction changes. For viscous discs, the boundary is found at H/R = 0.1−0.2, though coalescence is seen for low-viscosity, thick discs. Introducing a stratified thermal structure slows binary orbit evolution.
On the Wide-Band and Broadband Radio Technosignature Searches with Breakthrough Listen

description: Abstract: The search for extraterrestrial intelligence (ETI) at radio frequencies has largely been focused on continuous-wave narrowband signals. We demonstrate that different classes of wide-band and broadband pulsed beacons are energetically efficient compared to narrowband beacons over longer operational timescales. Searching for these unconventional signals enables us to constrain the existence of ETIs in proverbial multi-dimensional parameter space. These signal classes include wide-band periodic pulses akin to several powerful Earth-based air-traffic radars, 24 different types of wide-band signals with embedded modulations, and three different types of broadband signals with artificial dispersions. To scour for these 28 unique classes of signals, we have developed state-of-the-art search pipelines; leveraging advances made in the convolution/deep neural network classifiers and high-performance GPUs. We report on the first extensive survey for some of these signals towards 1883 stars in the solar neighborhood and in around half a million stars at the Galactic Center; utilizing around 250 hours of deep observations across 4 to 8 GHz using the Robert C. Byrd Green Bank Telescope as a part of the Breakthrough Listen program (Gajjar et al. 2021, 2022). Due to the absence of any signal-of-interest from our survey, we place a constraint on the existence of broadband beacons: < 1 in 1000 stars in the solar neighborhood (or in the spiral arm) and < 1 in half a million stars at the Galactic Center with broadband signal transmitter power densities of > 10^5 W/Hz and > 10^7 W/Hz, respectively. One of the major challenges in searching for these unconventional classes of signals from single dishes is the large number of false positives arising due to radio frequency interference. We will discuss how we are utilizing long-baselines of two widely-separated international LOw Frequency ARray (LOFAR) stations and band-limited spectral imaging of interferometers, such as the Giant Meterwave Radio Telescope (GMRT), to curb these challenges.
Free Speech or “Free Speech”? An Analysis of University Attitudes Towards Free Speech and the Chicago Statement

description: In 2014, the University of Chicago released the Chicago Statement, stating the school’s commitment to upholding free speech on its campus. Since 2014, over one hundred schools have endorsed this statement. This study examines the role that an endorsement of the Chicago Statement plays in a university’s attitude towards free speech and whether an endorsement is indicative of genuine attitudes towards free speech or used as a method of signaling what are considered positive traits. I begin by looking at the characteristics of schools using an ordered logit model of regression. I find that more “prestigious” schools are more likely to endorse the Chicago Statement, indicating the endorsement is used as a signal. Using time series data, I then set out to determine the temporal relationship between a school’s change in speech codes and an endorsement. I found that an endorsement of the Chicago Statement is both predicted by and a predictor for a positive change in speech codes. That is, an endorsement of the Chicago Statement comes in the midst of positive speech code reforms. These results would indicate that schools that have environments that are not associated with positive attitudes towards free speech, but that are undergoing positive speech reform, may offer genuine endorsements of the Chicago Statement.
Tet1 contributes to differentiation in the intestinal epithelium

description: The small intestine is composed of crypts that house intestinal stem cells (ISCs), which self-renew and differentiate to maintain the intestinal epithelium. Alternatively, intestinal villi contain absorptive enterocytes and secretory cells- goblet, enteroendocrine (EECs), tuft, and Paneth cells- that are derived from ISCs and maintain the gut's digestive and barrier functions. Chromatin is considered a major epigenetic component of cell identity and fate decision in embryonic and hematopoietic stem cell systems (Lara-Astiaso et al. 2014; Xie et al. 2013). However, the genetic and epigenetic mechanisms regulating ISC function remain poorly characterized. To better understand ISC regulation, we focused on Tet1, a chromatin modifying enzyme. Previous studies demonstrate Tet1 is essential for proper differentiation in embryonic stem cells and a tumor suppressor of hematopoietic malignancy, but Tet1’s role in the small intestine remains unknown (Ito et al. 2010; Cimmino et al. 2015). We hypothesized that Tet1 establishes distinct gene regulatory networks in ISCs to promote differentiation and repress proliferation. To avoid lethality and developmental defects on adult mice, we used a Tet1 inducible knockout mouse model (Tet1iKO) that provides specificity to ISCs. Through immunofluorescence staining, we quantified tuft, EECs, ISCs, proliferating, and S-phase cells in each mouse. Fluorescence and confocal microscopy revealed that Tet1iKO mice contained fewer tuft cells and EECs than the control mice, suggesting Tet1 drives ISC differentiation for tuft cell and EEC lineages. Additionally, the Tet1iKO mice contained more ISCs than the control mice. However, there was no significant change in the number of proliferating cells between the two groups of mice. Our results suggest Tet1 promotes ISC differentiation but does not affect ISC proliferation rates. Delineating the role of Tet1 in the establishment of specific ISC states will further our understanding of a Tet1-mediated ISC regulation pathway with applications to questions on intestinal damage and regeneration for digestive diseases.

description: A commutative ring is said to have ITI with respect to an ideal a if the a-torsion functor preserves injectivity of modules. Classes of rings with ITI or without ITI with respect to certain sets of ideals are identified. Behaviour of ITI under formation of rings of fractions, tensor products and idealisation is studied. Applications to local cohomology over non-noetherian rings are given.
Non-sinusoidal current and current reversals in a gating ratchet

description: In this work, the ratchet dynamics of Brownian particles driven by an external sinusoidal (harmonic) force is investigated. The gating ratchet effect is observed when another harmonic is used to modulate the spatially symmetric potential in which the particles move. For small amplitudes of the harmonics, it is shown that the current (average velocity) of particles exhibits a sinusoidal shape as a function of a precise combination of the phases of both harmonics. By increasing the amplitudes of the harmonics beyond the small-limit regime, departures from the sinusoidal behavior are observed and current reversals can also be induced. These current reversals persist even for the overdamped dynamics of the particles.

description: My thesis explores traditional Northwest Coast cultural objects as a vehicle for contemporary narratives. I researched the premise that the narratives in contemporary Northwest Coast Aboriginal art are derived from the convergence of formalism and culturally specific visual language. Formalism in Northwest coast art began in the late 1950s. In 1951 the potlatch ban, which made it illegal for Aboriginal’s to create or use cultural items in a traditional way, was lifted. I argue that the lifting of the ban allows for the challenging of formalist principles in Northwest Coast art. I situate my own practice as part of this legacy. I argue the convergence of formalism and the re-emergence of cultural teachings led to the formation of an approach to art practice I am calling Northwest Coast bilateralism. The artist creates and distinguishes between artworks for Aboriginal and non-Aboriginal audiences, the artworks may be aesthetically identical, but their context and use are very different. Northwest Coast bilateralism defines and is defined by this dual history of art production. It is what allows the contemporary Aboriginal artist to pull references from outside the traditional culture while still maintaining the aesthetics of traditional Northwest Coast Aboriginal art. The implication of bilateralism in contemporary Northwest Coast art is that it must always be interpreted according to two different systems of meaning and value. This thesis is a narrative account of my process of interpreting these theories.

description: We measure the resonance line shape of atomic vapor layers with nanoscale thickness confined between two sapphire windows. The measurement is performed by scanning a probe laser through resonance and collecting the scattered light. The line shape is dominated by the effects of Dicke narrowing, self-broadening, and atom-surface interactions. By fitting the measured line shape to a simple model we discuss the possibility to extract information about the atom-surface interaction.
