Prescribing Public-Private Partnerships to Global Health Initiatives
For six weeks I served as a finance intern with the Toilet Board Coalition (TBC) and created a Portfolio Presentation to deliver to TBCâs corporate board members in May. With my background in Public Health and interest in Corporate Social Responsibility and Sustainability, I was interested in learning how cross-sector partnerships can help accelerate global health development. My internship with TBC provided me with valuable firsthand experience in my topic of research, Public Private Partnerships (PPPs), which I was able to compare alongside a formal literature review. In this research paper I combine my research with my internship experience to show that while PPPs have weaknesses, they can serve as a valuable tool in global health development. I also make several recommendations for future research initiatives that would help overcome these weaknesses

Trajectories of spatial violence in Southeast Asian cities
This paper aims to reveal how urban âdevelopment-induced displacementâ (Koenig, 2015; Neef and Singer, 2015) shapes and perpetuates modalities of spatial violence in the context of rapidly urbanising Southeast Asia. While Southeast Asian postcolonial scholars have explored some manifestations of spatial violence such as displacement, a comprehensive regional analysis is still lacking, especially in relation to urbanisation impacts and planning.
Through a comparative lens, this study looks at the urban development contexts and histories of displacement in six cities; Ho Chi Minh, Bangkok, Manila, Jakarta, Phnom Penh, and Kuala Lumpur. We aim to trace patterns of resemblance and specificities in the trajectories of spatial violence using four analytical lenses: political regimes of urbanisation, exclusionary invisibility and disenfranchisement, housing provision policies, and the regulatory repertoires of displacement. Across the studied cities, pressure for economic development and the non-recognition of informal settlements, socially, politically and spatially, has facilitated their progressive erasure from the urban fabric. Spatial violence has often been an institutionalised practice, inscribed in policies and masterplansâseen particularly in authoritarian regimes and in the context of neoliberalisation of urban governance. While condemning âinformalityâ on the surface, authorities have often used illegal/informal practices to evict communities, violating domestic and international laws. We argue that spatial violence has been repeatedly justified with arguments invoking the interest of the public, like the vision of a beautiful city, climate adaptation, and infrastructure development; while, in the absence of adequate frameworks and provisions of housing, informality is both âtreatedâ with and produced by displacement
Visualizing Mechanics: Educational Videos Demonstrating Core Mechanics Concepts
There has been an increased interest in using technology to relay information over the past 20 years. This interest has been reflected in the way the internet has expanded to incorporate nearly-uncountable numbers of blogs, streaming videos, and discussion forums. Recent research has shown that younger generations of students prefer internet-based platforms such as these to communicate and learn, as they are congruent with a visual style of learning. The present study seeks to fuse the predominantly reflective and intuitive methods found in a traditional lecture with the more visual and active modes of learning to provide a larger range of learning opportunities. Specifically, the authors seek to create educational videos in the technical area of mechanics that are appealing to students, and useful in their studies. These videos encompass experimental activities and mathematical analyses associated with core mechanics topics. The videos provide necessary background information and a brief overview of the experiment, and then proceed with a demonstration and subsequent analysis. This format allows the students to fully grasp the topic of interest, and in many cases ties it to a real-life example. The authors believe that ultimately these videos will enhance student understanding by appealing to a variety of learning styles, and ultimately have a marked impact on pertinent student success metrics

Spitzer Imaging of i'-drop Galaxies: Old Stars at z~6
We present new evidence for mature stellar populations with ages >100Myr in
massive galaxies (M_stellar>10^10M_sun) seen at a time when the Universe was
less than 1Gyr old. We analyse the prominent detections of two z~6 star-forming
galaxies (SBM03#1 & #3) made at wavelengths corresponding to the rest-frame
optical using the IRAC camera onboard the Spitzer Space Telescope. We had
previously identified these galaxies in HST/ACS GOODS images of Chandra Deep
Field South through the "i-drop" Lyman break technique, and subsequently
confirmed spectroscopically with the Keck telescope. The new Spitzer photometry
reveals significant Balmer/4000Ang discontinuities, indicative of dominant
stellar populations with ages >100Myr. Fitting a range of population synthesis
models (for normal initial mass functions) to the HST/Spitzer photometry yields
ages of 250-650Myr and implied formation redshifts z~7.5-13.5 in
presently-accepted world models. Remarkably, our sources have best-fit stellar
masses of 1.3-3.8x10^10M_sun (95% confidence) assuming a Salpeter initial mass
function. This indicates that at least some galaxies with stellar masses >20%
of those of a present-day L* galaxy had already assembled within the first Gyr
after the Big Bang. We also deduce that the past average star formation rate
must be comparable to the current observed rate (SFR_UV~5-30M_sun/yr),
suggesting that there may have been more vigorous episodes of star formation in
such systems at higher redshifts. Although a small sample, limited primarily by
Spitzer's detection efficiency, our result lends support to the hypothesis
advocated in our earlier analyses of the Ultra Deep Field and GOODS HST/ACS
data. The presence of established systems at z~6 suggests long-lived sources at
earlier epochs (z>7) played a key role in reionizing the Universe.Comment: Accepted for publication in MNRAS (minor corrections made

Lateralized P3 deficit in schizotypal personality disorder
Background: Reduced, left-lateralized P3 amplitude has been reported in several studies focusing on electrophysiologic function in schizophrenia. Also, several lines of evidence suggest a similarity between schizophrenia and schizotypal personality disorder (SPD). This study was undertaken to determine the replicability of our previous finding of a left-lateralized P3 amplitude deficit in SPD. Methods: We recorded event-related potentials in 21 SPD and 18 normal control subjects in an auditory âoddballâ P3 paradigm. Results: In the SPD subjects, but not in the control subjects, there was lower P3 amplitude at T3 compared with T4. Conclusions: These results are similar to the ones in our previous work and further support the presence of a left-lateralized P3 deficit in SPD
Three Lyman-alpha Emitters at z approx 6: Early GMOS/Gemini Data from the GLARE Project
We report spectroscopic detection of three z~6 Lyman-alpha emitting galaxies,
in the vicinity of the Hubble Ultra Deep Field, from the early data of the
Gemini Lyman- at Reionisation Era (GLARE) project. Two objects,
GLARE#3001 (z =5.79) and GLARE#3011 (z =5.94), are new detections and are
fainter in (z'_{AB} =26.37 and 27.15) than any Lyman break galaxy
previously detected in Lyman-alpha. A third object, GLARE#1042 (z =5.83) has
previously been detected in line emission from the ground; we report here a new
spectroscopic continuum detection. Gemini/GMOS-S spectra of these objects,
obtained using nod & shuffle, are presented together with a discussion of their
photometric properties. All three objects were selected for spectroscopy via
the i-drop Lyman Break technique, the two new detections from the GOODS v1.0
imaging data. The red i'-z' colors and high equivalent widths of these objects
suggest a high-confidence z>5 Lyman-alpha identification of the emission lines.
This brings the total number of known z>5 galaxies within 9 arcmin of the
Hubble Ultra Deep Field to four, of which three are at the same redshift (z=5.8
within 2000 km/s suggesting the existence of a large-scale structure at this
redshift.Comment: 5 pages, 2 figures. Revised to match accepted versio
Post-weaning social isolation alters sociability in a sex-specific manner
Adolescence is a critical period for brain development in humans and stress exposure during this time can have lasting effects on behavior and brain development. Social isolation and loneliness are particularly salient stressors that lead to detrimental mental health outcomes particularly in females, although most of the preclinical work on social isolation has been done in male animals. Our lab has developed a model of post-weaning adolescent social isolation that leads to increased drug reward sensitivity and altered neuronal structure in limbic brain regions. The current study utilized this model to determine the impact of adolescent social isolation on a three-chamber social interaction task both during adolescence and adulthood. We found that while post-weaning isolation does not alter social interaction during adolescence (PND45), it has sex-specific effects on social interaction in young adulthood (PND60), potentiating social interaction in male mice and decreasing it in female mice. As early life stress can activate microglia leading to alterations in neuronal pruning, we next examined the impact of inhibiting microglial activation with daily minocycline administration during the first 3 weeks of social isolation on these changes in social interaction. During adolescence, minocycline dampened social interaction in male mice, while having no effect in females. In contrast, during young adulthood, minocycline did not alter the impact of adolescent social isolation in males, with socially isolated males exhibiting higher levels of social interaction compared to their group housed counterparts. In females, adolescent minocycline treatment reversed the effect of social isolation leading to increased social interaction in the social isolation group, mimicking what is seen in naĂŻve males. Taken together, adolescent social isolation leads to sex-specific effects on social interaction in young adulthood and adolescent minocycline treatment alters the effects of social isolation in females, but not males
The GLARE Survey II. Faint z=6 Ly-alpha Line Emitters in the HUDF
The galaxy population at z~6 has been the subject of intense study in recent
years, culminating in the Hubble Ultra Deep Field (HUDF) -- the deepest imaging
survey yet. A large number of high redshift galaxy candidates have been
identified within the HUDF, but until now analysis of their properties has been
hampered by the difficulty of obtaining spectroscopic redshifts for these faint
galaxies. Our ''Gemini Lyman-Alpha at Reionisation Era'' (GLARE) project has
been designed to undertake spectroscopic follow up of faint (z'<28.5) i'-drop
galaxies at z~6 in the HUDF. In a previous paper we presented preliminary
results from the first 7.5 hours of data from GLARE. In this paper we detail
the complete survey. We have now obtained 36 hours of spectroscopy on a single
GMOS slitmask from Gemini-South, with a spectral resolution of
lambda/Delta(lambda) ~ 1000. We identify five strong Lyman-alpha emitters at
z>5.5, and a further nine possible line emitters with detections at lower
significance. We also place tight constraints on the equivalent width of
Lyman-alpha emission for a further ten i'-drop galaxies and examine the
equivalent width distribution of this faint spectroscopic sample of z~6
galaxies. We find that the fraction of galaxies with little or no emission is
similar to that at z~3, but that the z~6 population has a tail of sources with
high rest frame equivalent widths. Possible explanations for this effect
include a tendency towards stronger line emission in faint sources, which may
arise from extreme youth or low metallicity in the Lyman-break population at
high redshift, or possibly a top-heavy initial mass function.Comment: 14 pages. MNRAS accepte
