Leveraging Lean Principles and Value Stream Mapping In A Low Resource Setting: The Jacaranda Health Approach
Creators: name: Alabi, Funmi
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2013

description: Jacaranda Health (JH), a start-up maternity health business operation, is building a network of private maternity clinics in resource-poor settings within third world countries. The goal is to provide affordable and quality care for the women and children in a patient-centered environment. Given this goal, and the limited resources available to both the organization and its clients, JH's business longevity and profitability relies on being innovative, adaptable, flexible and integrating the best clinical protocols, technologies, health information systems, and business approaches over the long run. To be successful in its vision and its business approach, quality improvement and management needs to be foundational to business practices at JH. As a first step, Lean, especially Value Stream Mapping (VSM) a quality management tool, was used to map out the business flows within and across business units. This paper focuses on quality management at Jacaranda Health, the VSM development processes and the associated activities in mapping and identifying both the services and business information flows within the clinic operations. It explores the current state, why VSM is needed, the roles and participants in the VSM workshop, how the clinical operation VSM was developed and its uses, the impact of VSM within JH's business, the challenges, and the best practices for moving forward with this model. JH is building a new clinic in another suburb of Nairobi and leveraging the lessons from the Ruiru clinic (used for this project) in the physical design, layout, and the associated clinical operation processes. JH is implementing a system wide Quality Improvement (QI) program, and putting in place a dedicated QI management resource. This resource will be available to lead all future VSM efforts and work cross functional across JH business units, coming up with processes that are well defined, repeatable, consistent, easily accessible and unambiguous to guide its operations.
Generalized effective description of loop quantum cosmology

description: The effective description of loop quantum cosmology (LQC) has proved to be a convenient platform to study phenomenological implications of the quantum bounce that resolves the classical big-bang singularity. Originally, this description was derived using Gaussian quantum states with small dispersions. In this paper we present a generalization to incorporate states with large dispersions. Specifically, we derive the \emph{generalized} effective Friedmann and Raychaudhuri equations and propose a generalized effective Hamiltonian which are being used in an ongoing study of the phenomenological consequences of a broad class of quantum geometries. We also discuss an interesting interplay between the physics of states with larger dispersions in standard LQC, and of sharply peaked states in (hypothetical) LQC theories with larger area gap.

description: Anomalies in time-series provide insights of critical scenarios across a range of industries, from banking and aerospace to information technology, security, and medicine. However, identifying anomalies in time-series data is particularly challenging due to the imprecise definition of anomalies, the frequent absence of labels, and the enormously complex temporal correlations present in such data. The LSTM Autoencoder is an Encoder-Decoder scheme for Anomaly Detection based on Long Short Term Memory Networks that learns to reconstruct time-series behavior and then uses reconstruction error to identify abnormalities. We introduce the Denoising Architecture as a complement to this LSTM Encoder-Decoder model and investigate its effect on real-world as well as artificially generated datasets. We demonstrate that the proposed architecture increases both the accuracy and the training speed, thereby, making the LSTM Autoencoder more efficient for unsupervised anomaly detection tasks.
Utopias, Magic Realism and Rebellious Spirits: Films of Christine Parker 1990 to 2000

description: Utopias, Magic Realism and Rebellious Spirits: Films by Christine Parker 1990-2000. “The More You Look, the more THERE IS to see…” From Hinekaro Goes on a Picnic and Blows up Another Obelisk (Christine Parker, Oceania Parker, 1995) In the 1990s New Zealand was in the grip of free market fundamentalism, neo-liberal deregulation of the economy having begun in the mid-eighties. The Maori protest movement was a major source of societal conflict and feminism had become the ‘F’ word. This study examines my writing and directing during the 1990s in New Zealand. It is proposed that the films contributed to national and international conversations around feminism, colonial struggles, spirituality and the supernatural. It is argued that these works offer a social critique of neoliberalism and the divisive effects of it, on women in particular. In the context of this appraisal neoliberalism is understood to be a set of beliefs that support the functioning of the global free market, with minimal government regulation, except to protect the functioning of private enterprise and the ownership of private property. The short films One Man’s Meat (1991), Peach (1993), and Hinekaro Goes on a Picnic and Blows up Another Obelisk (1995) and the feature film Channelling Baby (1999) are located in an oeuvre of female, Gay, and Maori film makers and artists responding to this environment. The recurrence of alternative utopias, the use of magic realism and the representation of the spiritual and supernatural in my work are also considered in relation to other films made in the period. A case is made that the films were part of a small vanguard of films responding to the 1990s status quo by offering alternative modes of discourse to the dominant economic rationalism. Rich in visual intensity and heightened narrative tropes, such as irony and fragmented narratives, my aesthetic choices, together with recurring themes of chance and fate, agency and identity, are considered to link the films together as a coherent study. While the works are located in an evolving feminist tradition in the 1990s, their continued relevance today, particularly in relation to foregrounding marginal voices and the disruption of dominant paradigms and expectations of female behaviour and identity, underpin the claim for originality.

description: Deep Reinforcement Learning (or just "RL") is gaining popularity for industrial and research applications. However, it still suffers from some key limits slowing down its widespread adoption. Its performance is sensitive to initial conditions and non-determinism. To unlock those challenges, we propose a procedure for building ensembles of RL agents to efficiently build better local decisions toward long-term cumulated rewards. For the first time, hundreds of experiments have been done to compare different ensemble constructions procedures in 2 electricity control environments. We discovered an ensemble of 4 agents improves accumulated rewards by 46%, improves reproducibility by a factor of 3.6, and can naturally and efficiently train and predict in parallel on GPUs and CPUs.
Prognosis of Health Literacy in the U.S. with Models, Programs, and Initiatives for Change

description: Health literacy, as defined by the Affordable Care Act of 2010, Title V, is the degree to which an individual has the capacity to obtain, communicate, process, and understand basic health information and services to make appropriate health decisions (Health and Human Services, 2010). Poor health literacy can affect how patients understand their health care providers and their instructions. Results of the National Assessment of Adult Literacy found that 12% of adults are listed as proficient when it comes to health literacy (Kutner et al., 2006). Health literacy is a global and domestic issue. With more effective ways of measuring and assessing health literacy, at-risk groups such as minorities and the elderly can make informed decisions about their health. This will eliminate redundancy in services, and will save the United States (U.S.) billions of dollars annually (Vernon, Trujillo, Rosenbaum, & DeBuono, 2014). Models to improve literacy will be discussed in this paper along with tools that are currently in place to help providers and public health researchers better assess literacy levels. Recommendations to improve communication with patients will be described as well as resources for empowerment.

description: Springtails (Collembola) have a nanostructured cuticle. To evaluate and to understand anti-biofouling properties of springtail cuticles’ morphology under different conditions, springtails, shed cuticles and cuticle replicates were studied after incubation with protein solutions and bacterial cultures using common in vitro models. In a second step, they were exposed to human oral environment in situ in order to explore potential application in dentistry. In vitro, the cuticular structures were found to resist wetting by albumin solutions for up to 3 h and colonization by Staphylococcus epidermidis was inhibited. When exposed in the oral cavity, initial pellicle formation was of high heterogeneity: parts of the surface were coated by adsorbed proteins, others remained uncoated but exhibited locally attached, ‘bridging’, proteinaceous membranes spanning across cavities of the cuticle surface; this unique phenomenon was observed for the first time. Also the degree of bacterial colonization varied considerably. In conclusion, the springtail cuticle partially modulates bioadhesion in the oral cavity in a unique and specific manner, but it has no universal effect. Especially after longer exposure, the nanotextured surface of springtails is masked by the pellicle, resulting in subsequent bacterial colonization, and, thus, cannot effectively avoid bioadhesion in the oral cavity comprehensively. Nevertheless, the observed phenomena offer valuable information and new perspectives for the development of antifouling surfaces applicable in the oral cavity.

description: The quantification of fat depots on the surroundings of the heart is an accurate procedure for evaluating health risk factors correlated with several diseases. However, this type of evaluation is not widely employed in clinical practice due to the required human workload. This work proposes a novel technique for the automatic segmentation of cardiac fat pads. The technique is based on applying classification algorithms to the segmentation of cardiac CT images. Furthermore, we extensively evaluate the performance of several algorithms on this task and discuss which provided better predictive models. Experimental results have shown that the mean accuracy for the classification of epicardial and mediastinal fats has been 98.4% with a mean true positive rate of 96.2%. On average, the Dice similarity index, regarding the segmented patients and the ground truth, was equal to 96.8%. Therfore, our technique has achieved the most accurate results for the automatic segmentation of cardiac fats, to date.

description: In this paper we address the problem of optimizing an unbalanced Mach-Zehnder interferometer, for a given pure input state and considering a specific detection scheme. While the optimum transmission coefficient of the first beam splitter can be uniquely determined via the quantum Fisher information only [Phys. Rev. A 105, 012604 (2022)], the second beam splitter transmission coefficient is detection-scheme dependent, too. We systematically give analytic solutions for the optimum transmission coefficient of the second beam splitter for three types of widely used detection schemes. We provide detailed examples including both Gaussian and non-Gaussian input states, showing when an unbalanced Mach-Zehnder interferometer can outperform its balanced counterpart in terms of phase sensitivity.

description: In this thesis we derive a higher order diffuse approximation of the Willmore energy from contributions by Karali and Katsoulakis [KK07], who studied a diffuse approximation of mean curvature flow. We prove Γ–convergence in smooth limit points for the sum of diffuse perimeter and the higher order diffuse Willmore energy in dimensions 2 and 3. Moreover, we prove the convergence on arbitrary time intervals towards weak solutions of mean curvature flow. We also consider a gradient-free diffuse approximation of the Willmore energy in the sense of Γ–convergence which we derive from a gradient-free diffuse approximation of the perimeter by Amstutz and van Goethem [AVG12]. We prove the lim sup–property for the Γ–convergence towards a multiple of the Willmore energy. In addition, we consider L2-type gradient flows of both diffuse Willmore energies, and give an asymptotic convergence result. Formally these constitute diffuse approximations of mean curvature flow and Willmore flow. In a restricted class of diffuse phase-field evolutions, we prove that these gradient flows convergence towards rescaled mean curvature flow and rescaled Willmore flow, respectively.

description: With the rapid development of self-supervised learning (e.g., contrastive learning), the importance of having large-scale images (even without annotations) for training a more generalizable AI model has been widely recognized in medical image analysis. However, collecting large-scale task-specific unannotated data at scale can be challenging for individual labs. Existing online resources, such as digital books, publications, and search engines, provide a new resource for obtaining large-scale images. However, published images in healthcare (e.g., radiology and pathology) consist of a considerable amount of compound figures with subplots. In order to extract and separate compound figures into usable individual images for downstream learning, we propose a simple compound figure separation (SimCFS) framework without using the traditionally required detection bounding box annotations, with a new loss function and a hard case simulation. Our technical contribution is four-fold: (1) we introduce a simulation-based training framework that minimizes the need for resource extensive bounding box annotations; (2) we propose a new side loss that is optimized for compound figure separation; (3) we propose an intra-class image augmentation method to simulate hard cases; and (4) to the best of our knowledge, this is the first study that evaluates the efficacy of leveraging self-supervised learning with compound image separation. From the results, the proposed SimCFS achieved state-of-the-art performance on the ImageCLEF 2016 Compound Figure Separation Database. The pretrained self-supervised learning model using large-scale mined figures improved the accuracy of downstream image classification tasks with a contrastive learning algorithm. The source code of SimCFS is made publicly available at https://github.com/hrlblab/ImageSeperation.

description: Zur Reduktion des Verbrauchs für Raumwärme und Warmwasser sowie Transformation des Wärmesektors bedarf es eines Ausbaus von energieeffizienten Wärmenetzen. Jedoch stellen geringe Anschlussquoten sowie fehlende Akzeptanz oftmals eine Herausforderung bei der Verdichtung und Neuimplementierung von Nah-/Fernwärmelösungen dar. Von besonderer Relevanz ist hierbei die Zielgruppe der Zwei- und Einfamilienhausbesitzer, die mit 16 Millionen die größte Kategorie im Gebäudebestand darstellt. Als möglicher weiterführender Erklärungsansatz für die Reaktanz von Hauseigentümern gegenüber einem Wärmenetzanschluss und die hohe Zufriedenheit mit (fossilen) Einzelgebäudeheizungen wurde sich im Rahmen der Dissertation dem noch weitestgehend unerforschten Konstrukt der subjektiv wahrgenommenen Versorgungsautonomie (VA) gewidmet. In einer ersten Studie wurden die Treiber und Hemmnisse von privaten Hauseigentümern gegenüber einem Nah-/Fernwärmeanschluss exploriert. Im Rahmen von 14 problemzentrierten Interviews mit Hauseigentümern und 8 Experteninterviews zeigte sich, dass insbesondere der starke Service-Charakter der Fernwärme, der Einfluss des Quartiers als sozialer Raum und vertragliche sowie technische Abhängigkeiten im Entscheidungsprozess eine Rolle spielen können. In diesem Zuge konnte zudem eine (Schein-)Autonomie – eine Diskrepanz zwischen subjektiver und technisch vorliegender Autonomie bei Einzelgebäudeheizungen – aufgedeckt werden. In einer zweiten Studie wurde im Rahmen einer standardisierten Umfrage mit privaten Hauseigentümern (n = 196) ein Messinstrument zur subjektiven VA im Wärmekontext entwickelt sowie nomologisch validiert. Zudem zeigte sich eine Wahrnehmungsverzerrung zwischen subjektiver und objektiver VA. In einem zweiten Modell konnten verschiedene Einflussfaktoren auf die Diskrepanz, wie die internale Kontrollüberzeugung und das Alter, nachgewiesen werden. Auf Basis der empirischen Ergebnisse wurden Handlungsempfehlungen abgeleitet, um (a) Eigentümer zu einem Wärmenetzanschluss zu aktivieren und (b) die subjektive VA im Rahmen der Wärmewende zu adressieren.

description: It is important for modern scanning microwave microscopes to overcome the effect of the surface roughness. Here, we report microwave conductivity imaging of the phase-separated iron chalcogenide K$_x$Fe$_y$Se$_2$ ($x=0.8$, $y=1.6$-$2$), in which electric conductivity-induced contrast is distinguished from topography-induced contrast using a combination of a scanning tunneling microscope and a scanning microwave microscope (STM-SMM). We observed the characteristic modulation of the local electric property that originates from the mesoscopic phase separation of the metallic and semiconducting phases in two different scanning modes: constant current (CC) mode and constant $Q$ (CQ) mode. In particular, CQ scanning is useful because we obtain a qualitative image in which the topographic contrast is largely eliminated without degradation of the spatial resolution.

description: Typical retrieval systems have three requirements: a) Accurate retrieval i.e., the method should have high precision, b) Diverse retrieval, i.e., the obtained set of points should be diverse, c) Retrieval time should be small. However, most of the existing methods address only one or two of the above mentioned requirements. In this work, we present a method based on randomized locality sensitive hashing which tries to address all of the above requirements simultaneously. While earlier hashing approaches considered approximate retrieval to be acceptable only for the sake of efficiency, we argue that one can further exploit approximate retrieval to provide impressive trade-offs between accuracy and diversity. We extend our method to the problem of multi-label prediction, where the goal is to output a diverse and accurate set of labels for a given document in real-time. Moreover, we introduce a new notion to simultaneously evaluate a method's performance for both the precision and diversity measures. Finally, we present empirical results on several different retrieval tasks and show that our method retrieves diverse and accurate images/labels while ensuring $100x$-speed-up over the existing diverse retrieval approaches.

Publisher: name: No Publisher Supplied
Year: 2023

description: Purpose of the Project: Obesity adversely affects many individuals across the United States, and it poses a significant risk for lifelong ailments of cardiovascular health, cancer, diabetes, and overall poor health outcomes. An estimated 2.4 billion individuals, 30% of the global population are affected by obesity. Despite the tremendous efforts of global, national, and state standards, the obesity epidemic has grown in rapid numbers. The purpose of this project is to utilize an education-based smartphone application as an intervention to alter obesogenic behaviors in patients with an elevated body mass index (BMI) of 27.0 and above.Methodology: Participants were recruited by convenience sampling, with a 12-week intervention utilizing an educational weight loss mobile application. The application assisted participants with customized material, and expert coaching. Participants completed a pre and post-test tool called the Diet self-efficacy survey. This tool delineated eating styles affected by temptation, negative emotional events, and social and intrinsic factors.Results: 41 participants that met the criteria completed the study. Inclusion criteria are 18 years and older, speaking English as a first language, > BMI 27 kg/m², and access to a mobile application. A Wilcoxon Signed Rank test was used to analyze baseline weight changes and three aspects (social and intrinsic scenarios, caloric intake temptations, and negative emotional events) of the Diet-SE efficacy tool. Results were found statistically significant (p<.001) for weight changes and behavioral changes over twelve weeks.Implications for Practice: The convenience of mobile use to track dietary behaviors empower patients to advocate for healthier food choices to promote weight loss. As mobile health technology grows, it enables patients to exercise an active role in their health. Therefore, Providers render better clinical decision-making to improve patient outcomes.

description: We propose a methodology to predict the cardiac epicardial and mediastinal fat volumes in computed tomography images using regression algorithms. The obtained results indicate that it is feasible to predict these fats with a high degree of correlation, thus alleviating the requirement for manual or automatic segmentation of both fat volumes. Instead, segmenting just one of them suffices, while the volume of the other may be predicted fairly precisely. The correlation coefficient obtained by the Rotation Forest algorithm using MLP Regressor for predicting the mediastinal fat based on the epicardial fat was 0.9876, with a relative absolute error of 14.4% and a root relative squared error of 15.7%. The best correlation coefficient obtained in the prediction of the epicardial fat based on the mediastinal was 0.9683 with a relative absolute error of 19.6% and a relative squared error of 24.9%. Moreover, we analysed the feasibility of using linear regressors, which provide an intuitive interpretation of the underlying approximations. In this case, the obtained correlation coefficient was 0.9534 for predicting the mediastinal fat based on the epicardial, with a relative absolute error of 31.6% and a root relative squared error of 30.1%. On the prediction of the epicardial fat based on the mediastinal fat, the correlation coefficient was 0.8531, with a relative absolute error of 50.43% and a root relative squared error of 52.06%. In summary, it is possible to speed up general medical analyses and some segmentation and quantification methods that are currently employed in the state-of-the-art by using this prediction approach, which consequently reduces costs and therefore enables preventive treatments that may lead to a reduction of health problems.

description: Precise spike timing as a means to encode information in neural networks is biologically supported, and is advantageous over frequency-based codes by processing input features on a much shorter time-scale. For these reasons, much recent attention has been focused on the development of supervised learning rules for spiking neural networks that utilise a temporal coding scheme. However, despite significant progress in this area, there still lack rules that have a theoretical basis, and yet can be considered biologically relevant. Here we examine the general conditions under which synaptic plasticity most effectively takes place to support the supervised learning of a precise temporal code. As part of our analysis we examine two spike-based learning methods: one of which relies on an instantaneous error signal to modify synaptic weights in a network (INST rule), and the other one on a filtered error signal for smoother synaptic weight modifications (FILT rule). We test the accuracy of the solutions provided by each rule with respect to their temporal encoding precision, and then measure the maximum number of input patterns they can learn to memorise using the precise timings of individual spikes as an indication of their storage capacity. Our results demonstrate the high performance of FILT in most cases, underpinned by the rule's error-filtering mechanism, which is predicted to provide smooth convergence towards a desired solution during learning. We also find FILT to be most efficient at performing input pattern memorisations, and most noticeably when patterns are identified using spikes with sub-millisecond temporal precision. In comparison with existing work, we determine the performance of FILT to be consistent with that of the highly efficient E-learning Chronotron, but with the distinct advantage that FILT is also implementable as an online method for increased biological realism.

description: This work proposes the use of Genetic Algorithms (GA) in tracing and recognizing the pericardium contour of the human heart using Computed Tomography (CT) images. We assume that each slice of the pericardium can be modelled by an ellipse, the parameters of which need to be optimally determined. An optimal ellipse would be one that closely follows the pericardium contour and, consequently, separates appropriately the epicardial and mediastinal fats of the human heart. Tracing and automatically identifying the pericardium contour aids in medical diagnosis. Usually, this process is done manually or not done at all due to the effort required. Besides, detecting the pericardium may improve previously proposed automated methodologies that separate the two types of fat associated to the human heart. Quantification of these fats provides important health risk marker information, as they are associated with the development of certain cardiovascular pathologies. Finally, we conclude that GA offers satisfiable solutions in a feasible amount of processing time.
Crack Use and HIV in African American Women

description: HIV is disproportionately prevalent among African American (AA) women nationally and in North Carolina specifically. AA women are also more likely to use crack some time in their lives than other ethnic groups due in part to poverty, distressed social support systems and disempowerment of gender relations. Crack is highly addictive and leads to transactional sex (TS) and inconsistent condom use which endangers the health of women and their partners. This paper tests the validity of that claim using data collected for a study at the University of North Carolina. A survey of 120 AA women incarcerated in North Carolina correctional facilities was conducted by faculty of the Division of Infectious Diseases in the Department of Medicine of the School of Medicine at the University of North Carolina. The study provided data on which to test the influence of crack use on TS and inconsistent condom use in this paper. Responding to over 100 survey questions, the participants answered questions about various life experiences including substance use, condom use practices and TS. Differences between crack users non- users of crack were measured using Pearson's chi-squared test. The data were analyzed using Stata version 12.1. Using crack even once in a person's life is found to be associated with HIV positive status in this sample. Women in this study who used crack were more likely to engage in TS. Crack use did not necessarily lead to inconsistent condom use. Understanding the influences of multilevel risk behaviors common in AA women's lives is important for identifying opportunities for culturally appropriate interventions which are further discussed using the social ecological model (SEM) to frame public health solutions.
