Cognitive Debiasing to Improve Diagnosis of Mood Disorders
Creators: name: Le, Kenny
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2018

description: Diagnosis of mental disorders should be as accurate as possible, particularly for a difficult subject such as depression and bipolar disorder. These mood disorders, the latter in particular, can be suspect to misdiagnosis from a number of reasons, including common comorbidities, symptom presentation during assessment, use of evidence-based practices, cultural differences, and the conceptualization of mental illness by the public and by clinicians. Some research has suggested cognitive biases may occur in clinical settings in a way that can lead to diagnostic inaccuracy, but there is little literature focused on practical applications to offset these heuristics. This study builds on previous research and tests how online tools can be used to improve diagnosis of mood disorders, particularly across different cultures including the United States and Asia. An online cognitive debiasing video presentation describing common heuristics and practical solutions to offset them was presented to participants in the experimental group, who were hypothesized to diagnose more accurately than the control group. All participants diagnosed and recommended treatment to short clinical vignettes based on actual cases. This study had several recruitment and retention problems, resulting in a small sample size to extract data from. Preliminary results suggested participants gave overall partially accurate diagnoses and that they learned something new from the debiasing module (M=3.50, SD=0.55). Future studies need to expand recruitment from professional samples, revamp information presentation, expand on implementation research, and prioritize applied practice of intervention techniques to improve diagnosis.

description: We present a very simple and fast algorithm for the numerical solution of viscoplastic flow problems without prior regularisation. Compared to the widespread alternating direction method of multipliers (ADMM / ALG2), the new method features three key advantages: firstly, it accelerates the worst-case convergence rate from $O(1/\sqrt{k})$ to $O(1/k)$, where $k$ is the iteration counter. Secondly, even for nonlinear constitutive models like those of Casson or Herschel-Bulkley, no nonlinear systems of equations have to be solved in the subproblems of the algorithm. Thirdly, there is no need to augment the Lagrangian, which eliminates the difficulty of choosing a penalty parameter heuristically. In this paper, we transform the usual velocity-based formulation of viscoplastic flow problems to a dual formulation in terms of the stress. For the numerical solution of this dual problem we apply FISTA, an accelerated first-order optimisation algorithm from the class of so-called proximal gradient methods. Finally, we conduct a series of numerical experiments, focussing on stationary flow in two-dimensional square cavities. Our results confirm that Algorithm FISTA*, the new dual-based FISTA, outperforms state-of-the-art algorithms such as ADMM / ALG2 by several orders of magnitude. We demonstrate how this speedup can be exploited to identify the free boundary between yielded and unyielded regions with previously unknown accuracy. Since the accelerated algorithm relies solely on Stokes-type subproblems and nonlinear function evaluations, existing code based on augmented Lagrangians would require only few minor adaptations to obtain an implementation of FISTA*.

description: The Preamble to the Indian Constitution states that- “WE, THE PEOPLE OF INDIA, havingsolemnly resolved to constitute India into a SOVEREIGN SOCIALIST SECULARDEMOCRATIC REPUBLIC and to secure to all its citizens:JUSTICE, social, economic and political.LIBERTY of thought, expression, belief, faith and worship.EQUALITY of status and of opportunity and to promote among them allFRATERNITY assuring the dignity of the individual and the unity and integrity of the Nation.IN OUR CONSTITUENT ASSEMBLY this twenty-sixth day of November 1949, do HEREBYADOPT, ENACT AND GIVE TO OURSELVES THIS CONSTITUTION.”1It is a reflection of the core constitutional values and declares India to be a Sovereign, Socialist,Secular, Democratic, Republic committed to Justice, Equality and Liberty for the people. Theobjective of the Competition Act, 2002, also reflects the same core values as our IndianConstitution. It clearly states the following objectives:• to prevent practices having adverse effect on competition.• to promote and sustain competition in markets.• to protect the interests of consumers.• to ensure freedom of trade carried on by other participants in markets, in India, andfor matters connected therewith or incidental thereto.It is here to be noted that prior to the Competition Act, 2002, the Monopolies and Restrictive TradePractices (MRTP) Act, 1969, was the first piece of legislation to deal with antitrust law in Indiaand to restraint the abuse of market power. However, at the wake of globalization, liberalizationand privatization the MRTP Act, 1969 was considered as obsolete and was replaced by theCompetition Act, 2002, on the recommendation of the Raghavan Committee.The Competition Act, 2002, as amended by the Competition (Amendment) Act, 2007, or theMRTP Act, 1969, were however not the first piece of legislation to deal with the antitrust lawglobally nor did it first originate in India. The antitrust law was for the very first time developedin the United States in the late nineteenth C.E.2.In this paper we will be making a detailed comparison between USA and India with respect toPrice Fixing, the related legislations and the agencies dealing with such issues in their respectivejurisdiction.
Building Walls and Breaking Laws: An Analysis of the European Union's Failure to Address the Migrant Crisis
Creators: name: Barkley, Allyson

Year: 2018

description: The European Union has a short, yet complicated history in which it has faced a number of diverse crises and conflicts, not the least of which is the refugee and migrant crisis that began in 2014. While the EU managed to unite and address crises past, it has failed to do so during this crisis. Not only are the states overwhelmed by the high number of arrivals and asylum applications, but several have actually gone against EU regulation and refused their assigned resettlement quotas, built walls, or enforced border controls. What is particular about the migrant crisis that has rendered the Union unable to address the situation, and what does this reveal about the deeper structural issues within the EU as an institution? I pose a three step answer to this question. First, the EU did not have mechanisms fit to handle the influx of migrants, and has failed to adapt appropriate mechanisms in a reasonable amount of time. Second, I argue that the failed response is in large part due to the historical deficiency of attention given to the laws, policies, and practices in the fields of foreign affairs, security and defense, and immigration and asylum at the supranational level. Lastly, the lack of attention is the result of an undefined power structure in those policy areas and a vague institutional identity.  This conflict creates an environment unfit for developing policy to which states will agree and follow obediently and results in ineffective solutions or no solutions at all. Ultimately, I recommend that the EU and its institutions work to define their goals and practices, and enforce stricter consequences for noncompliant member states.
Incorporating forest biodiversity and ecophysiology in watershed ecohydrologic models
Creators: name: Stewart, Andrea
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2016

description: Forests with species compositions that comprise different physiologic characteristics, such as stomatal conductance and xylem anatomy type, use different amounts of water and respond differently to climate conditions. In general, isohydric plants with diffuse-porous xylem anatomy are more susceptible to drought, while anisohydric plants with ring-porous xylem are less susceptible to drought and use less water. The biodiversity and spatial distribution of forests of different physiological types in the landscape may impact watershed hydrology and carbon cycling. However, few studies have used species-level ecophysiological information to inform catchment models or predict future watershed behavior. In this study, we use a spatially-distributed, process-based model, the Regional Hydro-Ecological Simulation System (RHESSys) to simulate a small water supply catchment in Chapel Hill, NC. We apply high resolution field data from the USDA Forest Service Forest Inventory and Analysis database to simulate six forest types with different physiologic types, an average forest type, and three single-tree-species forests. Results indicate that the biodiversity of forests significantly impacts streamflow quantity and patterns. Conversion of forests to diffuse-porous-dominated plants may result in decreased streamflow relative to ring-porous-dominated plants. Conversion to evergreen plants may cause fundamentally different streamflow patterns, especially in the winter months. This work will aid the modeling efforts of future local and regional water supply and help us understand the hydrologic impacts of changing forest landscapes at the species level due to changing climate and forest management actions.

Our first two hypotheses are based on the original study and imply an effect of age-based hiring discrimination and that an objectivity-priming increases this effect. Additionally, we suggest that by adding a name that is congruent to the numeric age the discrimination effect will be enhanced.

description: The success of deep learning models depends on the size and quality of the dataset to solve certain tasks. Here, we explore how far generated data can aid real data in improving the performance of Neural Networks. In this work, we consider facial expression recognition since it requires challenging local data generation at the level of local regions such as mouth, eyebrows, etc, rather than simple augmentation. Generative Adversarial Networks (GANs) provide an alternative method for generating such local deformations but they need further validation. To answer our question, we consider noncomplex Convolutional Neural Networks (CNNs) based classifiers for recognizing Ekman emotions. For the data generation process, we consider generating facial expressions (FEs) by relying on two GANs. The first generates a random identity while the second imposes facial deformations on top of it. We consider training the CNN classifier using FEs from: real-faces, GANs-generated, and finally using a combination of real and GAN-generated faces. We determine an upper bound regarding the data generation quantity to be mixed with the real one which contributes the most to enhancing FER accuracy. In our experiments, we find out that 5-times more synthetic data to the real FEs dataset increases accuracy by 16%.

description: Traditionally, chaotic systems are built on the domain of infinite precision in mathematics. However, the quantization is inevitable for any digital devices, which causes dynamical degradation. To cope with this problem, many methods were proposed, such as perturbing chaotic states and cascading multiple chaotic systems. This paper aims at developing a novel methodology to design the higher-dimensional digital chaotic systems (HDDCS) in the domain of finite precision. The proposed system is based on the chaos generation strategy controlled by random sequences. It is proven to satisfy the Devaney's definition of chaos. Also, we calculate the Lyapunov exponents for HDDCS. The application of HDDCS in image encryption is demonstrated via FPGA platform. As each operation of HDDCS is executed in the same fixed precision, no quantization loss occurs. Therefore, it provides a perfect solution to the dynamical degradation of digital chaos.

THE GOLDBACH-LINNIK PROBLEM: SOME CONDITIONAL RESULTS
Creators: name: ROSSI, ANTONELLA
Publisher: name: Universit� degli Studi di Milano
Year: 2011

description: This work concerns the Goldbach-Linnik problem, which is a variation of Goldbach's one: here the goal is to prove that all large even integers can be written as a sum of two primes and k powers of 2, where k is a fixed positive integer. Assuming the Generalized Riemann Hypothesis, first we prove two results on the size of the exceptional set of the Goldbach-Linnik problem, which is the set of the even integer that can not be written as a sum of two primes and k powers of 2. To do this first we analyze the size of the exceptional set in short intervals, which are intervals of type [N;N+H] with N that tends to infinity and H = o(N), then in intervals of type [N; 2N]. Furthermore we study the Goldbach-Linnik problem from another point of view, that is that to find conditionally a value k0 such that every sufficiently large even integer has a representation as a sum of two primes and k0 powers of 2. Finally we analyze the real analogous of the Goldbach-Linnik problem, that concerns the numbers of the form l1*p1+l2*p2+t1*2^(m1)+...+ts*2^(ms) , with l1, l2, t1,...,ts real numbers not all equal to one and p1, p2 primes. Also in this case we study the problem conditionally. The main technique that we use to prove our results is the circle method applied in different way for every result. In fact, for example, we have to insert the method of Pintz-Ruzsa to do computations that involve the powers of 2 and to prove the last result we have to change the set of integration from S^1 to the real line, such that the method becomes different.
Win Together, Lose Alone: How Attributions of Blame Pinpoint and Praise Generalize
Creators: name: Frasca, Teresa
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2015

description: We’ve all played the blame game before, pointing the finger at someone for the downfall of our projects. When we succeed, however, everyone’s contributions are recognized and celebrated. In this study, we proposed the “Win Together, Lose Alone” phenomenon. Consistent with Barbara Frederickson’s research on how positivity broadens thought and negativity narrows it, we propose that when we are successful in our endeavors, our positivity opens us up to praising many people, but when we fail, our negativity narrows our focus to blaming just one person. The current research examines this phenomenon of blaming one but praising many in four domains: athletics, group work, corporations, and parent-child relationships. Through surveys, participants rated the moral responsibility and praiseworthiness/blameworthiness of individuals in each domain. Data suggests that more individuals are praised than individuals who are blamed, supporting the “Win Together, Lose Alone” phenomenon. This repeated effect speaks to the way we assign praise and blame in daily life and how we navigate the moral arena.

description: Measurements of spin excitations are essential for an understanding of spin-mediated pairing for superconductivity; and resonant inelastic X-ray scattering (RIXS) provides a considerable opportunity to probe high-energy spin excitations. However, whether RIXS correctly measures the collective spin excitations of doped superconducting cuprates remains under debate. Here we demonstrate distinct Raman- and fluorescence-like RIXS excitations of Bi$_{1.5}$Pb$_{0.6}$Sr$_{1.54}$CaCu$_{2}$O$_{8+δ}$ in the mid-infrared energy region. Combining photon-energy and momentum dependent RIXS measurements with theoretical calculations using exact diagonalization provides conclusive evidence that the Raman-like RIXS excitations correspond to collective spin excitations, which are magnons in the undoped Mott insulators and evolve into paramagnons in doped superconducting compounds. In contrast, the fluorescence-like shifts are due primarily to the continuum of particle-hole excitations in the charge channel. Our results show that under the proper experimental conditions RIXS indeed can be used to probe paramagnons in doped high-$T_c$ cuprate superconductors.
Mini Spindles TOG1 Maintains Microtubule Polymerization Rates and Mitotic Spindle Formation
Creators: name: Lowe, Benjamin
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2017

description: Microtubules (MTs) are dynamic polymers that regulate cellular processes including
intracellular trafficking and mitotic spindle formation. MT-associated proteins (MAPs) control
MT dynamics in space and time in order to ensure proper cellular function. Members of the
XMAP215 protein family are conserved MAPs that utilize arrays of αβ-tubulin-binding tumor
overexpressed gene (TOG) domains to promote rapid MT polymerization. Higher eukaryotic
XMAP215 proteins possess a pentameric TOG array that is structurally diverse despite being
positionally conserved across species. Previous studies show that a TOG1-2-5 array is sufficient
to promote endogenous MT polymerization rates. Furthermore, multiple studies of XMAP215
family members demonstrate that removing TOG1 and TOG2 from the pentameric array
completely abrogates MT growth rates. However, the significance of TOG1 alone in regulating
MT dynamics remains uncertain. We investigated TOG1’s role in promoting MT polymerization
and mitotic spindle formation using the Drosophila melanogaster (D.m.) XMAP215 family
member Mini Spindles (Msps) as a model. Endogenous Msps was depleted from D.m. S2 cells
using dsRNA and a Msps construct with TOG1 deleted (ΔTOG1) from the pentameric TOG
domain array was expressed. ΔTOG1-expressing cells exhibited dramatically reduced MT
polymerization rates in comparison to control cells. Furthermore, ΔTOG1 expression yielded a
significantly decreased incidence of normal bipolar spindle phenotypes. These data suggest that
TOG1 is critical for proper XMAP215-mediated MT dynamics and mitotic spindle formation.
Together, these findings lead to a more comprehensive model of how distinct TOG domains
contribute to XMAP215 function. These results also provide a foundation on which to study
other TOG-domain containing MAPs.

description: For more than two years, we monitored with the HARPS-N spectrograph the 400 Myr-old star HD\,63433, which hosts two close-in (orbital periods $P_b\sim7.1$ and $P_c\sim20.5$ days) sub-Neptunes detected by the TESS space telescope, and it was announced in 2020. Using radial velocities and additional TESS photometry, we aim to provide the first measurement of their masses, improve the measure of their size and orbital parameters, and study the evolution of the atmospheric mass-loss rate due to photoevaporation. We tested state-of-the-art analysis techniques and different models to mitigate the dominant signals due to stellar activity that are detected in the radial velocity time series. We used a hydro-based analytical description of the atmospheric mass-loss rate, coupled with a core-envelope model and stellar evolutionary tracks, to study the past and future evolution of the planetary masses and radii. We derived new measurements of the planetary orbital periods and radii ($P_b=7.10794\pm0.000009$ d, $r_b=2.02^{+0.06}_{-0.05}$ $R_{\oplus}$; $P_c=20.54379\pm0.00002$ d, $r_c=2.44\pm0.07$ $R_{\oplus}$), and determined mass upper limits ($m_b\lesssim$11 $M_{\oplus}$; $m_c\lesssim$31 $M_{\oplus}$; 95$\%$ confidence level), with evidence at a 2.1--2.7$σ$ significance level that HD\,63433\,c might be a dense mini-Neptune with a Neptune-like mass. For a grid of test masses below our derived dynamical upper limits, we found that HD\,63433\,b has very likely lost any gaseous H-He envelope, supporting HST-based observations that are indicative of there being no ongoing atmospheric evaporation. HD\,63433\,c will keep evaporating over the next $\sim$5 Gyr if its current mass is $m_c\lesssim$15 $M_{\oplus}$, while it should be hydrodynamically stable for higher masses.

Relationship as a moderator for the association between perceived parental disapproval and willingness to self-disclose about alcohol exposure in adolescence
Creators: name: Miller, Corey
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2013

description: Research focusing on how to prevent adolescents from drinking due to the unhealthy consequences of alcohol has found parental disapproval to be a useful tool in prevention. However, parental disapproval has also been associated with lower rates of adolescent self-disclosure, which can be harmful considering parents receive most of their knowledge about their adolescents from their adolescents. Authoritative parenting is thought to be conducive to the wants and needs of adolescents and may provide what is necessary to meet the goals of disapproval and disclosure. The current study proposed that the positive relationship between parents and adolescents that comes about from authoritative parenting could moderate the relationship between parental disapproval of adolescent alcohol exposure and the adolescent’s willingness to self-disclose about alcohol exposure. A questionnaire evaluating alcohol exposure, perceived caregiver disapproval, perceived relationship quality with one’s caregiver, and willingness to self-disclose about alcohol exposure was administered to a sample of middle school adolescents (n=27). Results indicated that having a positive relationship quality played a preventative role in lower adolescent alcohol exposure despite caregiver disapproval. However, having a positive relationship quality did not make adolescents more willing to self-disclose about their alcohol exposure, indicating that adolescents who perceive positive relationships with caregivers do not want to disappoint them. Future studies should incorporate larger sample sizes and should investigate alcohol exposure while comparing middle school and high school populations.
Developing LEAF-BUD: a medical education course with a strong focus on its faculty to maximise learning potential
Creators: name: Von Essen, Anna
name: Sturgess, Jane
Publisher: name: F1000 Research Limited
Year: 2023

description: Background:
 Medical education courses can improve teaching skills not only through relating content, but by faculty demonstrating core skills during the course. This necessitates a robust faculty selection process, training, and continuing faculty development to refine these skills. LEAF-BUD, a 1-day medical education course for junior doctors in the East of England deanery, places a strong emphasis on both its faculty and delegates’ learning.

 Summary of work:
 Plenaries and small group sessions cover learning theory, teaching plans, presentation skills & virtual delivery, feedback, and facilitation & mentoring. We have run 12 course dates in total, with up to 21 delegates each.
 LEAF-BUD offers many opportunities for faculty development beyond an initial training day, including individualised feedback following every course, tailored biannual faculty development days where higher-order facilitation skills are honed, shortlisting and interviewing new faculty, and being supported in leadership positions. Social events also allow networking amongst the highly invested faculty.

 Summary of Results:
 Course evaluations have been overwhelmingly positive; immediate feedback data (84% response rate) demonstrates course modules’ average ratings on a 5-point Likert scale between 4.40 and 4.61. Delayed (2-month) feedback data shows long-term improvement, e.g. in having a range of techniques to manage the ‘difficult’ learner (pre-course 12.5% agree or strongly agree, vs. post-course 94%).
 Faculty retention has been excellent, with only 2 faculty leaving out of 29 since our first course in July 2021 and several staying on despite moving out of the region or achieving consultant posts. One faculty member described LEAF-BUD as “[a] programme that has pushed me outside my comfort zone… I look forward to more and more learning experiences.”

 Discussion and Conclusion:
 Course evaluations and testimonials consistently highlight the skilled faculty as a valuable resource. The greatest challenge lies in sustainability; devising and organising effective development opportunities can be time-consuming. This is reduced when faculty members are invited to express their own development needs. In addition, faculty are more willing to volunteer time and effort to developing course materials when they feel personally valued. We hope that LEAF-BUD can be a model for other medical education courses.

description: We examine what happens if we replace ZFC with a localistic/relativistic system, LZFC, whose central new axiom, denoted by $Loc({\rm ZFC})$, says that every set belongs to a transitive model of ZFC. LZFC consists of $Loc({\rm ZFC})$ plus some elementary axioms forming Basic Set Theory (BST). Some theoretical reasons for this shift of view are given. All $Π_2$ consequences of ZFC are provable in ${\rm LZFC}$. LZFC strongly extends Kripke-Platek (KP) set theory minus $Δ_0$-Collection and minus $\in$-induction scheme. ZFC+``there is an inaccessible cardinal'' proves the consistency of LZFC. In LZFC we focus on models rather than cardinals, a transitive model being considered as the analogue of an inaccessible cardinal. Pushing this analogy further we define $α$-Mahlo models and $Π_1^1$-indescribable models, the latter being the analogues of weakly compact cardinals. Also localization axioms of the form $Loc({\rm ZFC}+ϕ)$ are considered and their global consequences are examined. Finally we introduce the concept of standard compact cardinal (in ZFC) and some standard compactness results are proved.

A female paratype derives from the west coast of Sumatra, but Szymczakowski (1964) suspects this specimen may actually belong to the related P. tarsalis Szymczakowski. Our material provides the first localities outside of Singapore: in the Malaysian states of Pahang and Selangor, which suggests the species is more widely distributed across the Malay Peninsula. The new specimens closely match Szymczakowski’s (1970) redescription.

Increasing water use demands and a changing regional climate are affecting hydrological systems, and consequently impacting the quality and quantity of water availability to communities, industries and the environment.As part of the Australian Government’s Exploring for the Future program, the UDF project is working in collaboration with State partners to collect and integrate new data and information with existing hydrogeological knowledge. The goal is to provide analyses and products that assist water managers to increase water security in the region, with a focus on groundwater resources. As part of this project we are assessing the occurrence of, and geological controls on, potable water resources within the Darling Alluvium (DA), which comprises unconsolidated sediments (<140 m thick) associated with the modern and paleo-Darling River. The DA’s relationship to the underlying Eromanga, Surat (Great Artesian Basin) and Murray basins is also important, particularly in the context of potential groundwater sources or sinks, and connection between low and high quality groundwater resources. At least one major fault system is known to influence groundwater flow paths and control groundwater-surface water interaction.Data collection across the project area has commenced, with an airborne electromagnetic (AEM) survey already complete, and new geophysical, hydrochemical and hydrodynamic data being acquired. Preliminary interpretation of the new AEM data in conjunction with existing geological and hydrogeological information has already revealed the major paths and geometries of the paleo-Darling River, given important insights into fault controls on groundwater flow paths, and shown variation in the thickness, distribution and character of the DA, which has direct implications for groundwater–surface water connectivity.

 10 Οκτ. 2023, Παγκόσμια ημέρα για την ψυχική υγεία Είναι αυτονόητο αλλά καθόλου δεδομένο πως χρειάζεται να δίνουμε σημασία στην ψυχική μας υγεία. Αλήθεια, πώς τη βιώνουμε στην καθημερινότητά μας; Για κάποιον νέο ή και μεγαλύτερο μπορεί να διαπιστώσουμε πως «σφύζει από υγεία». Σφύζω σημαίνει πάλλομαι. Παρομοίως, για την ψυχική μας υγεία χρειάζεται να είμαστε σε επαφή με τον παλμό της ζωής που μας διατρέχει, να παρατηρούμε πώς εκφράζεται μέσα από το σώμα και την προσωπικότητά μας και προς ποιες κατευθύνσεις λογισμών και πράξεων μας κινητοποιεί. Με στόχο την προαγωγή της ψυχικής υγείας επιχειρήσαμε να επανερμηνεύσουμε την θεωρία των πρωταρχικών αναγκών του Maslow και να συνοδεύσουμε κάθε ιεραρχημένη ανθρώπινη ανάγκη με ένα ερώτημα για προσωπική διερεύνηση και θεραπευτική στοχοθέτηση. Η ψυχική υγεία είναι ζητούμενο για όλους!
A Tale of Three Mysterious Spectral Features in Carbon-Rich Evolved Stars: The 21 Micrometer, 30 Micrometer, and "Unidentified Infrared" Emission Features

description: The mysterious "21 micrometer" emission feature seen almost exclusively in the short-lived protoplanetary nebula (PPN) phase of stellar evolution remains unidentified since its discovery two decades ago. This feature is always accompanied by the equally mysterious, unidentified "30 micrometer" feature and the so-called "unidentified infrared" (UIR) features at 3.3, 6.2, 7.7, 8.6, and 11.3 micrometer which are generally attributed to polycyclic aromatic hydrocarbon (PAH) molecules. The 30 micrometer feature is commonly observed in all stages of stellar evolution from the asymptotic giant branch (AGB) through PPN to the planetary nebula phase. We explore the interrelations among the mysterious 21 micrometer, 30 micrometer, and UIR features in the Galactic and Magellanic Cloud of the 21 micrometer sources. We derive the fluxes emitted in the observed UIR, 21 micrometer, and 30 micrometer features from published ISO or Spitzer/IRS spectra. We find that none of these spectral features correlate with each other. This argues against a common carrier (e.g., thiourea) for both the 21 micrometer feature and the 30 micrometer feature (otherwise these two features should correlate). This also does not support large PAH clusters as a possible carrier for the 21 micrometer feature.

Side-by-Side: Supporting Pregnant Adolescents through Partnership with Birth Partners UNC Volunteer Doulas
Creators: name: Reid, Caroline S.
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2015

description: Pregnant and postpartum adolescents often face significant physical, social, and
psychological challenges as they transition to parenthood. These challenges can include poor
pregnancy and birth outcomes, lack of social support, anxiety and stress, breastfeeding
difficulties, and postpartum depression (Chen, Wen, Fleming, Demissie, Rhoads, & Walker,
2007, Shah, Gee, & Theall, 2013, Hall, Coley, Labbok, Cupito, Nwokah, 2012, Maxson &
Miranda, 2011). Because adolescents have unique needs during pregnancy, birth and the
postpartum period, many benefit from additional support (Gentry, Nolte, Gonzalez, Pearson, &
Ivey, 2010). A trained and skilled labor companion (a doula) can offer such support. The
following paper contains a literature review on adolescent pregnancy and doula care.
Information gathered from this literature review was then used to create a new initiative designed
to increase and improve doula care for adolescents planning to give birth at N.C. Women’s
Hospital. This initiative, called Side-by-Side, pairs pregnant adolescents with a Birth Partner
volunteer doula. The Birth Partner doulas were specifically trained on working with pregnant
and postpartum adolescents, and a workbook was developed to guide two prenatal and two
postpartum meetings between the doula(s) and an adolescent client. The purposes of the
meetings are to (1) build a positive relationship between the doula and adolescent, (2) foster
feelings of attachment between the adolescent and her baby, and (3) provide information on
birth, breastfeeding, and newborn behavior that is accessible to adolescents. The doulas are also
expected to attend their client’s births, during which they provide additional physical, emotional,
and informational support. By implementing evidence-based practices, the Side-by-Side program
offers the benefits of doula care, tailored to fit the unique circumstances of adolescent mothers.

description: We show that any co-orientable foliation of dimension two on a closed orientable $3$-manifold with continuous tangent plane field can be $C^0$-approximated by both positive and negative contact structures unless all the leaves are simply connected. As applications we deduce that the existence of a taut $C^0$-foliation implies the existence of universally tight contact structures in the same homotopy class of plane fields and that a closed $3$-manifold that admits a taut $C^0$-foliation of codimension-1 is not an $L$-space in the sense of Heegaard-Floer homology.

LncRNA Cyrano in Neural Differentiation of Embryonic Stem Cells
Creators: name: Miller, Sarah
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2018

description: The goal of this project is to elucidate long non-coding RNA Cyrano’s role in the neural differentiation pathway of embryonic stem cells (ESCs). Currently, long non-coding RNAs (lncRNAs) are known to be prolifically expressed, with nonprotein-coding transcripts consisting of a large portion of the human transcriptome, but their functions are understudied and not well unders tood. The studies that have been executed show that lncRNAs are impactful on gene expression and developmental processes. Further, misregulation of lncRNAs has been implicated in many diseases, including neurodegenerative disorders. It is crucial to investigate Cyrano as a key player in neural differentiation to delineate the function of a paradigmal lncRNA to build the foundation of understanding of lncRNA functions as a whole. Additionally, the implication of Cyrano in neural differentiation will further understanding of the gene expression network necessary for neural differentiation. Although further studies will be necessary, investigation of Cyrano may prove to be an informative step in understanding gene regulation of neural differentiation. Our data points to a suppressor role for Cyrano in neural differentiation, with a loss of Cyrano function resulting in an increase in neural differentiation and may suggest an interplay with miR-7 in this context.
Probing the Role of Carbon in the Interstellar Ultraviolet Extinction

description: We probe the role of carbon in the ultraviolet (UV) extinction by examining the relations between the amount of carbon required to be locked up in dust [C/H]_dust with the 2175 Angstrom extinction bump and the far-UV extinction rise, based on an analysis of the extinction curves along 16 Galactic sightlines for which the gas-phase carbon abundance is known and the 2175 Angstrom extinction bump exhibits variable strengths and widths. We derive [C/H]_dust from the Kramers-Kronig relation which relates the wavelength-integrated extinction to the total dust volume. This approach is less model-dependent since it does not require the knowledge of the detailed optical properties and size distribution of the dust. We also derive [C/H]_dust from fitting the observed UV/optical/near-infrared extinction with a mixture of amorphous silicate and graphite. We find that the carbon depletion [C/H]_dust tends to correlate with the strength of the 2175 Angstrom bump, while the abundance of silicon depleted in dust shows no correlation with the 2175 Angstrom bump. This supports graphite or polycyclic aromatic hydrocarbon (PAH) molecules as the possible carrier of the 2175 Angstrom bump. We also see that [C/H]_dust shows a trend of correlating with 1/R_V, where R_V is the total-to-selective extinction ratio, suggesting that the far-UV extinction is more likely produced by small carbon dust than by small silicate dust.

description: We investigate the rank gradient and growth of torsion in homology in residually finite groups. As a tool, we introduce a new complexity notion for generating sets, using measured groupoids and combinatorial cost. As an application we prove the vanishing of the above invariants for Farber sequences of subgroups of right angled groups. A group is right angled if it can be generated by a sequence of elements of infinite order such that any two consecutive elements commute. Most non-uniform lattices in higher rank simple Lie groups are right angled. We provide the first examples of uniform (co-compact) right angled arithmetic groups in $\mathrm{SL}(n,\mathbb{R}),~n\geq 3$ and $\mathrm{SO}(p,q)$ for some values of $p,q$. This is a class of lattices for which the Congruence Subgroup Property is not known in general. Using rigidity theory and the notion of invariant random subgroups it follows that both the rank gradient and the homology torsion growth vanish for an arbitrary sequence of subgroups in any right angled lattice in a higher rank simple Lie group.
