description: Das plataformas que hospedam podcast, duas serão brevemente apresentadas em artigo científico, quais sejam: PodCloud, plataforma descontinuada no Brasil em julho de 2023, e Podcastics, escolhida para a migração do podcast devido ao seu custo-benefício. Assim, a escolha por apresentar, sucintamente, essas duas plataformas justifica-se pelo fato de gerenciarmos um podcast acadêmico como parte das atividades da gestão de projetos em biblioteca universitária, o qual passou por uma dupla transição no ano de 2023: a migração da plataforma de hospedagem, da PodCloud para a Podcastics, e a alteração do nome do podcast, tendo em vista a sua nova proposta de atuação na podosfera.
Relationships among Chronic Pain, Hypervigilance, and Executive Function

Year: 2017

description: This research study explores the effects of a history of chronic pain on current pain perception
and executive function. We asked participants to report any chronic pain earlier in life and to
indicate the ages at which it occurred. Two measures of executive function were used. The
Operation Span (OSPAN) test measured the ability to move numerical and verbal information in
and out of working memory, while the Stroop task tested the ability to suppress salient but
irrelevant information in the form of color names. We also studied the ability of one pain to
modulate another (conditioned pain modulation, CPM), a perceptual analogue of executive
function (Yarnitsky, 2015). To measure CPM, we asked subjects to rate pressure stimuli on one
arm while the opposite hand was placed either in painfully cold or thermally neutral water, and
compared the two sets of ratings. Catastrophizing and hypervigilance were also measured,
because these perceptual/cognitive habits can sometimes influence pain. Analyses statistically
compared these five measures of central processing in individuals with and without a history of
chronic pain and found individuals with a later age of first experience with chronic pain had
higher Stroop effect scores, suggesting lessened ability to inhibit information. An independent
samples t-test found that people with a history of chronic pain experience less CPM. These
findings suggest that central inhibition is negatively impacted by chronic pain. There were also
significant positive correlations between measures of hypervigilance and weighted-rod sensation
ratings. Future studies should focus on the age of first chronic pain as a factor in executive
function and pain modulation.

description: The NO$ν$A collaboration has constructed a 14,000 ton, fine-grained, low-Z, total absorption tracking calorimeter at an off-axis angle to an upgraded NuMI neutrino beam. This detector, with its excellent granularity and energy resolution and relatively low-energy neutrino thresholds, was designed to observe electron neutrino appearance in a muon neutrino beam, but it also has unique capabilities suitable for more exotic efforts. In fact, if an efficient upward-going muon trigger with sufficient cosmic ray background rejection can be demonstrated, NO$ν$A will be capable of a competitive indirect dark matter search for low-mass WIMPs. The cosmic ray muon rate at the NO$ν$A far detector is about 100 kHz and provides the primary challenge for triggering and optimizing such a search analysis. The status of the NO$ν$A upward-going muon trigger is presented.

description: Functional Magnetic Resonance Imaging (fMRI) is a non-invasive technique for studying brain activity. During an fMRI session, the subject executes a set of tasks (task-related fMRI study) or no tasks (resting-state fMRI), and a sequence of 3-D brain images is obtained for further analysis. In the course of fMRI, some sources of activation are caused by noise and artifacts. The removal of these sources is essential before the analysis of the brain activations. Deep Neural Network (DNN) architectures can be used for denoising and artifact removal. The main advantage of DNN models is the automatic learning of abstract and meaningful features, given the raw data. This work presents advanced DNN architectures for noise and artifact classification, using both spatial and temporal information in resting-state fMRI sessions. The highest performance is achieved by a voting schema using information from all the domains, with an average accuracy of over 98% and a very good balance between the metrics of sensitivity and specificity (98.5% and 97.5% respectively).

description: An ethnographic study conducted in order to investigate agritourist satisfaction in the Mediterranean Island of Cyprus brings to the surface novel information in regards to motivation; the formation of expectations; satisfaction achievement; and behavioural intentions, of agritourists. The findings of the study contribute to the existing body of knowledge in the field of tourism by divulging further details regarding the relatively unexplored niche market of agritourists. Further to this and perhaps more importantly, the fieldwork findings assist destinations and practitioners alike to achieve guest satisfaction and foster the positive future behavioural intentions of their guests.

Unwanted Americans?: Undocumented Youth with "American Dreams"
Creators: name: Vargas, Mireille

Year: 2012

description: This qualitative study documents the experiences of three undocumented Latino youth
each at a different level—the elementary, middle, and high school levels. These case studies and
oral histories from unique perspectives of undocumented students from traditional two-parent
homes in a small town (located near a major transportation hub and approximately forty-five
miles away from two major cities) in the Piedmont in North Carolina serve to further the current
research on undocumented youth and address a research gap. Through observation and
ethnographic structured and semi-structured interviews about (a) their school and home
environments; (b) work, school, and family history; (c) migration history; and (d) educational,
social, and occupational aspirations in relation to being an undocumented immigrant and how
this influences their aspirations and actions in work, in school, at home, and in their social life, I
relate their stories through a combination of historiography and narrative inquiry methods to
explore how their legal status affects them during that particular stage in their life. Furthermore, I
interviewed their parents and observed their families to grasp a deeper understanding of the
students’ lives.

description: Given the rapid recent trend of urbanization, a better understanding of how urban infrastructure mediates socioeconomic interactions and economic systems is of vital importance. While the accessibility of location-enabled devices as well as large-scale datasets of human activities, has fueled significant advances in our understanding, there is little agreement on the linkage between socioeconomic status and its influence on movement patterns, in particular, the role of inequality. Here, we analyze a heavily aggregated and anonymized summary of global mobility and investigate the relationships between socioeconomic status and mobility across a hundred cities in the US and Brazil. We uncover two types of relationships, finding either a clear connection or little-to-no interdependencies. The former tend to be characterized by low levels of public transportation usage, inequitable access to basic amenities and services, and segregated clusters of communities in terms of income, with the latter class showing the opposite trends. Our findings provide useful lessons in designing urban habitats that serve the larger interests of all inhabitants irrespective of their economic status.

Novel Bioreactor Design: Development of a Bioartifical Liver for Multiplexing with Serial Organ Systems for Pharmaceutical Testing
Creators: name: Hans, Vaibhav
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2014

description: Even in this age of medicine, acute liver disease is still primarily treated in the
same way as a decade ago; through the use of a liver transplant. However, due to the
increase in liver disease and the persistent shortage of donor organs, the development of a
bioartificial liver (BAL) has been the center of many research projects around the world.
Even so, in the last two decades, there has only been little advancement on the
development of a suitable human liver representative bioreactor. Although tissue-engineering
methods have improved, a bioreactor still needs to be developed that can
emulate the liver in order to properly develop and test hepatocytes to be used in a
bioartificial liver. This BAL model must be able to first of all maintain cell viability, as
well as mimic gas exchange and nutrient delivery. However, the development of a
suitable BAL is prolonged due to the financial aspect of pharmacology testing. The cost
of testing a single pharmaceutical compound on hepatocytes in vivo can exceed millions
of dollars in order to satisfy government regulations. The fact is that there are many new
compounds that are synthesized each year that could fight liver disease, but the cost of in
vivo testing is far too high [8]. By creating a BAL to model the in vivo pathways and
mechanisms in the liver, an understanding of integration and the effects of consequent
pharmaceutical compounds can be expedited and testing can be made more affordable.

description: Spin-momentum locking is a unique intrinsic feature of strongly spin-orbit coupled materials and a key to their promise of applications in spintronics and quantum computation. Much of the existing work, in topological and non-topological pure materials, has been focused on the orthogonal locking in the vicinity of the $Γ$ point where the directions of spin and momentum vectors are locked perpendicularly. With the orthogonal case, enforced by the symmetry in pure systems, mechanisms responsible for non-orthogonal spin-momentum locking (NOSML) have drawn little attention, although it has been reported on the topological surface of $α$-$Sn$. Here, we demonstrate that, the presence of the spin-orbit scattering from dilute spinless impurities can produce the NOSML state in the presence of a strong intrinsic spin-orbit coupling in the pristine material. We also observe an interesting coupling threshold for the NOSML state to occur. The relevant parameter in our analysis is the deflection angle from orthogonality which can be extracted experimentally from the spin-and-angle-resolved photoemission (S-ARPES) spectra. Our formalism is applicable to all strongly spin-orbit coupled systems with impurities and not limited to topological ones. The understanding of NOSML bears on spin-orbit dependent phenomena, including issues of spin-to-charge conversion and the interpretation of quasiparticle interference (QPI) patterns as well as scanning-tunneling spectra (STS) in general spin-orbit coupled materials.

Innovation in the Oil Futures Market: Expanding Fixed-Rate Contracts into the Consumer Facing Retail Market
Creators: name: Goronkin, Shane I.
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2016

description: The oil industry is constantly plagued by radical shifts in supply and volatile fluctuations in prices. Many of the industry’s largest consumers will adopt price hedging strategies through the use of futures contracts in order to become protected from unpredictable movements in the cost of oil and gasoline. The adopters of this strategy have realized significant returns which suggest that a similar model could be offered to the general individual consumers of gasoline. This purpose of this research is to evaluate this unexploited opportunity and to determine the best model of expanding into the model of fixed-price gasoline contracts for the general consumer. The research demonstrates a high degree of value creation for both the consumer and the retailer: in any given timeframe between 2008-2016, consumers who logically exercise the fixed-rate contracts save an average of $.70 per gallon while the retailer receives an incremental return of $.61 per gallon through the price hedging usage of futures contracts.
Bounding Cross-Country Human Capital Variation
Creators: name: Basse, Michael
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2015

description: This paper explores a possible limitation of generalized human capital models that operate by relaxing the assumption that skilled and unskilled labor are perfect substitutes. We make use of the notion that, when skilled and unskilled labor are rather inelastic, countries with relatively few skilled workers should offer large skill premiums compared to countries where skilled labor is relatively abundant. We introduce the a priori assumption that the price of skilled labor should be higher in developed countries than in undeveloped ones, and see that as skilled and unskilled labor become increasingly inelastic, generalized human capital models can attribute the majority of cross-country income differences to human capital variation only at the cost of violating this a priori assumption. We argue that this implies a bound on the substitution elasticity between skilled and unskilled labor that effectively bounds the contribution of human capital to cross-country income differences. This supports the notion that a theory of Total Factor Productivity is necessary to explain income variation across countries.

description: It is spatial dispersion which is exclusively responsible for the emergence of exchange interaction and magnetic ordering. In contrast, magneto-crystalline anisotropy present in any realistic material brings in a certain non-linearity to the equation of motion. Unlike homogeneous ferromagnetic ordering a variety of non-collinear ground state configurations emerge as a result of competition among exchange, anisotropy, and dipole-dipole interaction. These particle-like states, e.g. magnetic soliton, skyrmion, domain wall, form a spatially localised clot of magnetic energy. In this paper we explore topologically protected magnetic solitons that might potentially be applied for logical operations and/or information storage in the rapidly advancing filed of solitonics (and skyrmionics). An ability to easily create, address, and manipulate such structures is among the prerequisite forming a basis of -onics technology, and is investigated in detail here using numerical and analytical tools.
Understanding the Patient's Journey: A Case Study in Scleroderma Pain Management

description: Unlike with the treatment of other rheumatic conditions with chronic pain, such as rheumatoid
arthritis or fibromyalgia, pain is not currently a diagnostic criterion for systemic sclerosis, and,
in fact, little is actually known about the quantity and quality of pain present with this disease.
While there is currently scant literature on the subject of pain control in SSc, what is out there
demonstrates a knowledge gap with how to effectively treat the chronic multifocal pain from this
disease. The purpose of this paper is to examine a case study of a person who had diffuse systemic
scleroderma for 11 years, until her death from the disease at age 61, and to look at the course of
her pain experience and treatment for that pain. A review of the current literature will be
conducted to determine the barriers to effective pain treatment for SSc. The most appropriate
treatments will be discussed, and suggestions will be made for how to best move forward with pain
management for people suffering from this debilitating disease.

description: ABSTRACT Pauropsylla depressa Crawford (Homoptera : Psyllidae) infests Ficus glomerata Roxb. and produces galls on its leaves, causing extensive damage to the foliage of the plant. The gall formation by Pauropsylla depressa causing the changes in the histomorphology of the host plant. Galls are pathologically developed cells, tissue and organs of plants, which have risen mostly by hypertrophy and hyperplasia (excessive cell division) usually under the influence of parasitic organism. Galls are epiphyllous, simple, globular, sessile, per foliate unilocular. Usually also in large fleshy, multilocular agglomerate masses. The physiology of gall formation is still obscure and it is generally believed that a secretion from nymph emerges out of the gall and moults into adult. Thickness of wall depending upon the size of gall and gall cavity. External surface of gall is shiny greenish, brown or pinkish developing upon the depending stage of P. depressa inside the gall. Outer layer is made of cuticle. Newly formed galls are green in colour, but as the gall grows due to the metaplacia induced by the feeding of instars in it, gall colour changes pale green. Later on, it develops brownish spots. The colour of galls changes with the development of instars (from 1st instar nymph to 5th instar) inside the galls. After some time, greenish colour turns brown. During winter, mature gall turns pinkish due to the formation of some phenolic compounds. Mature gall contains a lacerated opening on the lower surface (ventral side) of the gall from which fifth instar nymph escapes out for moulting into imago. With the development of instar, the size of the galls also increases (Plate 1). As the size of the nymph increase, subsequently size of the gall also increases. Newly formed gall (young gall) measures 1.5 to 2.0 mm in diameter mature gall measures 10 to 12 mm in diameter and all gall measures 11 to 13 mm in diameter. Attains maximum size of 20 to 30 mm in diameter. However whenever entire leaf turned gallinaceous, then agglomerated mass measured 8 to 12 cm. Agglomerated masses may reach up to 14 to 53 mm in diameter.

description: We study the embedding property in the category of sorted profinite groups. We introduce a notion of the sorted embedding property (SEP), analogous to the embedding property for profinite groups. We show that any sorted profinite group has a universal SEP-cover. Our proof gives an alternative proof for the existence of a universal embedding cover of a profinite group. Also our proof works for any full subcategory of the sorted profinite groups, which is closed under taking finite quotients, fibre product, and inverse limit. We also introduce a weaker notion of finitely sorted embedding property (FSEP), and it turns out to be equivalent to SEP. The advantage of FSEP is to be able to be axiomatized in the first order language of sorted complete systems. Using this, we show that any sorted profinite group having SEP has the sorted complete system whose theory is $ω$-stable under the assumption that the set of sorts is countable. In this case, as a byproduct, we get the uniqueness of a universal SEP-cover of a sorted profinite group, which generalizes the uniqueness of an embedding cover of a profinite group.

Publisher: name: tourismos
Year: 2009

description: This paper presents the results of an empirical research that aims to (a) identify the criteria on which the cruise companies select a homeport, and (b) conclude on the hierarchy that each of these criteria is prioritised. A broad literature review, along with brainstorming sessions, concluded on a wide list of potential criteria. Based on these findings, a questionnaire was developed and distributed to experts that include cruise companies, agents and cruise ports. The analysis of the collected data determines the criteria on which the cruise industry chooses a homeport and the gravity that each criterion has on their decision. Based on the empirical findings, the paper draws up potential strategies for a cruise terminal in order to become a leading cruise port. As competition between cruise ports intensifies, and the cruise industry is increasingly marked by concentration, the provided responses are of vital importance for the future development of cruise ports and, more general, maritime tourism.

description: Nurses spend the most time at the bedside and need to have the knowledge, skills, and comfort level to take care of patients at the end of their lives. The purpose of this project was to look at factors affecting nurses’ comfort with end-of-life conversations through literature review, and to increase my own comfort level with end-of-life conversations through reflection. This paper covers two parts: one of my literature review to look at nurses’ level of comfort with end-of-life conversations, and one of my own experience and reflection. During the first half of the year, I completed role plays on end-of-life conversations with myself in the role of the nurse, and then, finding a knowledge deficit, I searched the literature on advance directive information and end-of-life decisions in order to increase my knowledge base. In the second half of the year, I completed the ELNEC (End-of-Life Nursing Education Consortium, 2018) modules to increase my knowledge further, completed the second set of end-of-life role plays, and performed the literature review on factors that affect nurses’ comfort with end-of-life conversations. At the end, I reflected on how increasing my knowledge and experience with end-of-life conversations through role plays and literature reviews affected my own comfort level.

description: Brains and sensory systems evolved to guide motion. Central to this task is controlling the approach to stationary obstacles and detecting moving organisms. Looming has been proposed as the main monocular visual cue for detecting the approach of other animals and avoiding collisions with stationary obstacles. Elegant neural mechanisms for looming detection have been found in the brain of insects and vertebrates. However, looming has not been analyzed in the context of collisions between two moving animals. We propose an alternative strategy, Generalized Regressive Motion (GRM), which is consistent with recently observed behavior in fruit flies. Geometric analysis proves that GRM is a reliable cue to collision among conspecifics, whereas agent-based modeling suggests that GRM is a better cue than looming as a means to detect approach, prevent collisions and maintain mobility.

In codimension 3, we show that there is no torsion if $\dim X\ge 11$. This extends the analogous results in characteristic different from 2, obtained by Karpenko in the nineteen-nineties.

globalization participation. Further analysis determines that no single economic
institutional indicator strongly relates to positive globalization participation; however,
collectively the indicators imply a relationship.

CONVICT HERITAGE TOURISM: A CASE STUDY OF FREMANTLE PRISON, AUSTRALIA
Creators: name: Kumar, Kapil
Publisher: name: tourismos
Year: 2009

description: History and Heritage have traditionally been strong pull factors in tourism. There are countries and destinations with strong tradition in these areas with practically no efforts needed for product designing, promotion or marketing. Destinations like Rome, Vienna or Paris, etc. can be cited in this regard. It is interesting to find that a country like Australia with a history of approximately 200 years (excluding the aborigines’ history) has made extensive use of its history and heritage by converting them into tourism products and convict heritage tourism has emerged as a vital interest area for both domestic as well as international tourism. As a visiting fellow of the Australia India Council (2007) I worked on a project – “How Australia has converted its history and heritage into tourism products?” and further as a visiting Professor under the Australia Endeavour Award 2008 I worked on Convict Heritage in Australia. For this I carried out extensive fieldwork in different parts of Australia. This paper analyses the decision-making and planning for converting convict history and sites into convict heritage sites and further developing them as tourism products. It examines the attractions created in this area and the way they are marketed and promoted. After discussing the broad areas the paper discusses the Fremantle prison as a case study whereby it takes into account its conversion into a convict heritage site and its enrichment into a tourism product by introducing prison tours, theme parties and a live experience of prison life to the visitors. How do the visitors feel about this experience is another aspect dealt with in the paper along with the perceptions and attitudes of the host population, former prison officers and members of the Town Council in Fremantle. The paper also makes certain suggestions for further enrichment and rejuvenation of such tourism products in Australia. The paper, by dealing such themes, provides an insight into this emerging area of new tourism products that provide a successful tourism product case study for others to learn from and follow.

description: This paper considers unconstrained convex optimization problems with time-varying objective functions. We propose algorithms with a discrete time-sampling scheme to find and track the solution trajectory based on prediction and correction steps, while sampling the problem data at a constant rate of $1/h$, where $h$ is the length of the sampling interval. The prediction step is derived by analyzing the iso-residual dynamics of the optimality conditions. The correction step adjusts for the distance between the current prediction and the optimizer at each time step, and consists either of one or multiple gradient steps or Newton steps, which respectively correspond to the gradient trajectory tracking (GTT) or Newton trajectory tracking (NTT) algorithms. Under suitable conditions, we establish that the asymptotic error incurred by both proposed methods behaves as $O(h^2)$, and in some cases as $O(h^4)$, which outperforms the state-of-the-art error bound of $O(h)$ for correction-only methods in the gradient-correction step. Moreover, when the characteristics of the objective function variation are not available, we propose approximate gradient and Newton tracking algorithms (AGT and ANT, respectively) that still attain these asymptotical error bounds. Numerical simulations demonstrate the practical utility of the proposed methods and that they improve upon existing techniques by several orders of magnitude.

description: Der gesellschaftliche Blick auf sexuelle und geschlechtliche Vielfalt hat sich in den letzten Jahrzehnten verändert. Doch nach wie vor sind nicht-heterosexuelle und nicht-cisgeschlechtliche Lebensweisen in Deutschland keine Selbstverständlichkeit. Das zeigt sich z. B. daran, dass in sozialwissenschaftlichen Jugendstudien lesbische, schwule, bisexuelle, trans und queere (LSBTQ-)Lebensweisen weiterhin kaum berücksichtigt werden. Die Folge ist ein Mangel an Erkenntnissen über ihre Lebenssituation. Die Ergebnisse der bundesweiten Studie Coming- out – und dann …?! zeigen, welche Erfahrungen LSBTQ-Jugendliche bei ihrem inneren und äußeren Coming-out in alltäglichen Lebensbereichen wie Familie, Bildungs und Arbeitsorten und dem Freundeskreis machen und welche Diskriminierungserfahrungen sie dort erleben. Außerdem wird deutlich, wie sie mit Herausforderungen und Problemen umgehen, die aufgrund einer heteronormativen Zwei-Geschlechter-Ordnung bestehen. Über 5 000 lesbische, schwule, bisexuelle, trans und queere Jugendliche haben in einer Online-Befragung Auskunft über ihre Erlebnisse gegeben. Außerdem wurden deutschlandweit 40 problemzentrierte Interviews mit LSBTQ-Jugendlichen geführt, in denen sie von ihren Erfahrungen und Umgangsweisen berichtet haben.

description: Social attitudes to sexual und gender diversity have changed in recent decades. Nevertheless, non-heterosexual and non-cisgender ways of life are still not normal. For example, empirical research on young people hardly takes account of lesbian, gay, bisexual, transgender and queer lifestyles. The consequence is a lack of knowledge about their lives. The results of the nationwide study Coming out – and then …?! show how young LGBTQ people experience the process of self-awareness and coming out. The study focuses on their daily lives in a family, educational and work context and amongst their peers and shows what kind of discrimination these adolescents face. It also reveals the challenges and problems they face living in a heteronormativity- based society. More than 5,000 young people took part in an online survey. In addition, 40 problem centered interviews were conducted across Germany in which these young people talked about their individual experiences and behaviours. The article presents an overview of the key results of the study Coming out – and then …?!

description: Deep hedging (Buehler et al. 2019) is a versatile framework to compute the optimal hedging strategy of derivatives in incomplete markets. However, this optimal strategy is hard to train due to action dependence, that is, the appropriate hedging action at the next step depends on the current action. To overcome this issue, we leverage the idea of a no-transaction band strategy, which is an existing technique that gives optimal hedging strategies for European options and the exponential utility. We theoretically prove that this strategy is also optimal for a wider class of utilities and derivatives including exotics. Based on this result, we propose a no-transaction band network, a neural network architecture that facilitates fast training and precise evaluation of the optimal hedging strategy. We experimentally demonstrate that for European and lookback options, our architecture quickly attains a better hedging strategy in comparison to a standard feed-forward network.

description: Magnetic quantum periodicity in the dc voltage is observed when asymmetric rings are switched between superconducting and normal state by a noise or ac current. This quantum effect is used for detection of a non-equilibrium noise with the help of a system of 667 asymmetric aluminum rings of $1 \ μm$ in diameter connected in series. Any noise down to the equilibrium one can be detected with the help of such system with enough great number of asymmetric rings.

Medium-Term Impacts of Hurricane Matthew on Water Quality: Assessing Fecal Source Tracking Markers
Creators: name: Lempp, Rachel

description: Hurricane Matthew caused heavy flooding in eastern North Carolina in October 2016,raising concerns about impacts on local water quality. Beginning in December 2016, samples were collected from paired surface water, well water, and tap water sites in Robeson County. Samples (n=120) were collected on ten sampling dates between December 2016 and August 2017 and were used to assess water connectivity and water quality and to determine duration of impacts. This sub-study focused on testing samples for microbial source tracking (MST) markers to identify possible sources of fecal contamination. We used a novel duplex droplet digital polymerase chain reaction (ddPCR) assay to simultaneously determine gene copy numbers of swine (Pig-2-bac) and human (HF183) MST markers. Results showed detection of human markers in 30% (n=47) of surface water samples at an average concentration of 43 gene copies of HF183 per 100 mL of water. Human markers were found persistently at site 3B on 100% of sampling dates (n=10). No swine markers were found in any samples. Tested well and tap water samples were all negative for the targeted MST markers, suggesting that flooding from Hurricane Matthew did not have medium-term impacts on human or swine fecal contamination in drinking water. The ddPCR assay developed here shows promise for environmental applications and could prove to be a valuable tool for MST.

"I Have: Cancer" An Educational Tool for Pediatric Patients with Intellectual and Developmental Disabilities and an Oncological Diagnosis
Creators: name: Cotton, Elizabeth Bradley
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2015

description: I have hypothesized a series of educational booklets that can be used to help pediatric
patients with intellectual and developmental disabilities (I/DD) navigate an inpatient stay. For this project I have focused on pediatric cancer and created the first booklet, “I Have: Cancer.” I envision the “I Have” series to expand and encompass more diseases and conditions as I continue my career and education. From my own experience and after consulting with people with multidisciplinary experience with pediatric I/DD, what seemed most helpful to the pediatric patient would be an individualized and interactive approach to patient education. This care booklet could be an inclusive and appropriate method of explanation of cancer for interdisciplinary use. My intention is to promote appropriate language and terminology, advocate for pediatric patients with I/DD and their families, and above all, to educate these patients about the process of having cancer and being hospitalized. The hospital can be an alarming place for any child, and
for those with I/DD it can be, confusing, and frightening, and disruptive to the routines that can be a source of comfort to them. I hope to alleviate some of the stress that these pediatric patients may experience, and provide a tool for communication between pediatric patients with I/DD and their caregivers. After working with this population, I found it imperative to not only research, but to also provide an appropriate resource or tool for pediatric patients with I/DD, as the needs of these
individuals differ from the standard needs of traditional pediatric patients. Children with I/DD are a diverse group whom healthcare professionals will inevitably see in practice. Nurses should be prepared to provide individualized, meaningful, quality care including patient education.

description: Finite-time coherent sets (FTCSs) are distinguished regions of phase space that resist mixing with the surrounding space for some finite period of time; physical manifestations include eddies and vortices in the ocean and atmosphere, respectively. The boundaries of finite-time coherent sets are examples of Lagrangian coherent structures (LCSs). The selection of the time duration over which FTCS and LCS computations are made in practice is crucial to their success. If this time is longer than the lifetime of coherence of individual objects then existing methods will fail to detect the shorter-lived coherence. It is of clear practical interest to determine the full lifetime of coherent objects, but in complicated practical situations, for example a field of ocean eddies with varying lifetimes, this is impossible with existing approaches. Moreover, determining the timing of emergence and destruction of coherent sets is of significant scientific interest. In this work we introduce new constructions to address these issues. The key components are an inflated dynamic Laplace operator and the concept of semi-material FTCSs. We make strong mathematical connections between the inflated dynamic Laplacian and the standard dynamic Laplacian [Froyland 2015], showing that the latter arises as a limit of the former. The spectrum and eigenfunctions of the inflated dynamic Laplacian directly provide information on the number, lifetimes, and evolution of coherent~sets.
A Daytime Measurement of the Lunar Contribution to the Night Sky Brightness in LSST's ugrizy Bands-- Initial Results

description: We report measurements from which we determine the spatial structure of the lunar contribution to night sky brightness, taken at the LSST site on Cerro Pachon in Chile. We use an array of six photodiodes with filters that approximate the Large Synoptic Survey Telescope's {\it u, g, r, i, z,} and {\it y} bands. We use the sun as a proxy for the moon, and measure sky brightness as a function of zenith angle of the point on sky, zenith angle of the sun, and angular distance between the sun and the point on sky. We make a correction for the difference between the illumination spectrum of the sun and the moon. Since scattered sunlight totally dominates the daytime sky brightness, this technique allows us to cleanly determine the contribution to the (cloudless) night sky from backscattered moonlight, without contamination from other sources of night sky brightness. We estimate our uncertainty in the relative lunar night sky brightness vs. zenith and lunar angle to be 10\,\%. This information is useful in planning the optimal execution of the LSST survey, and perhaps for other astronomical observations as well. Although our primary objective is to map out the angular structure and spectrum of the scattered light from the atmosphere and particulates, we also make an estimate of the expected number of scattered lunar photons per pixel per second in LSST, and find values that are in overall agreement with previous estimates.
