Cascading and Multisensory Influences on Speech Perception Development
Creators: name: Choi, Dawoon

Publisher: name: Wiley
Year: 2019

description: Over the first weeks and months following birth, infants’ initial, broad-based perceptual sensitivities become honed to the characteristics of their native language. In this paper, we review this process of emerging specialization within the context of a cascading “critical period” (CP) framework, in which periods of maximal openness to experience of different aspects of language occur at sequential, overlapping points in development. Importantly, as infants’ experience of speech is not limited to auditory signals, but is informed by – for example – their experience of talking faces and their own oral motor movements, we review the trajectory of perceptual specialization in multisensory language processing. Throughout, we highlight the impact of increasing perceptual specialization on later language outcomes (e.g. word learning, foundations of syntax, literacy), and consider how the outcomes can be compromised if/when the timing of perceptual specialization has been perturbed.

description: The study is an attempt to investigate long-run and short-run relationships between gross domestic product (GDP) and agricultural GDP of Bangladesh applying the Vector Error Correction Model (VECM). The data published by the BBS for the period 1972-73 to 2015-16 was used. As preconditions of VECM, the stationarity of the time series data and co-integration of the variables were tested. The GDP and agricultural GDP in logarithm forms were found integrated of the order one (d=1) and co-integration of rank one (r=1).The coefficient (beta) of estimated long-run equilibrium equation was positive and significant implying a long-run equilibrium relationship between GDP and agricultural GDP. A positive and significant time trend was also observed in the co-integrating equation. Both coefficients (alpha) of the error correction terms (ECTs) in the VECM, which indicate the rates of short-run adjustments towards the long-run equilibrium, were negative and significant confirming consistency with the theory. Since both ECTs were negative and significant, there was a long-run bi-directional causality running from agricultural GDP to GDP and vice-versa. Responding to a positive shock in agricultural GDP, the GDP gradually increases while due to shock in GDP, the agricultural GDP decreases in the initial stage and increases gradually thereafter. Various post-estimation specification tests were performed and the estimated parameters of the model were found consistent and efficient.

description: Cancer is one of the leading threats to health in Canada and the world. While a large proportion of cancer can be prevented – 30-50% or even more - cancer prevention research has been under-studied, under-funded and under-applied. In recognition of the potential of cancer prevention research, and the need for directed resources, the Canadian Cancer Society British Columbia Yukon (CCS BCY) endowed a permanent Chair in Cancer Primary Prevention at The University of British Columbia (UBC) in 2008, with Dr. Carolyn Gotay as the inaugural Chair holder. The next step was to establish the Centre of Excellence in Cancer Prevention (CoECP), to build infrastructure and address some of the research gaps. The CoECP has been developed in a partnership between Dr. Carolyn Gotay at UBC, and the CCS BCY. The goals of the CoECP are to reduce cancer incidence and risk factors through new research, dissemination of existing knowledge, and by increasing connections among and between researchers, practitioners, policy makers, and the public. The CoECP has collaborated to develop programs in research, education, and knowledge exchange, all of which contribute to its potential to increase the scope, salience, and impact of cancer prevention research, and play a significant role in decreasing cancer incidence in Canada.

description: This dissertation begins with the observation that there is often a haunted quality to the built environment of former carceral spaces, sometimes explicit and sometimes denied, concerning structures that either sit empty or in ruin, or have been repurposed and put to new use. This haunted quality can suggest a rupturing through of the past into the present that is often difficult to exorcize. In some cases, this haunting is utilized by developers as a form of dark heritage, which celebrates this past as a means of revenue generation. In other cases, it becomes a nuisance for developers who would rather forget, deny, or ignore the uncomfortable past as they attempt to rebrand and repurpose. Moreover, these sites are entangled within the local, vernacular discourse often overlooked by memory scholars who tend to focus on discourses of civic or national public memory.
description: In the cases I examine—Eastern State Penitentiary, Athens Lunatic Asylum, and Camarillo State Hospital—there is an explicit element of hauntedness derived from systematic traumas related to mental illness or imprisonment that leaves traces within the built environment, thus marking each site as different from national sites of public memory. Instead, the haunted sites of memory that I will investigate are often a strange mixture of history, heritage and haunting, of public and private redevelopment—in some cases, with ghosts sold as part of the package. I intend to show that the ghosts or uncanny effects, which circulate at these former sites of incarceration, mark an uncomfortable liminal space, not yet fully recognized or understood by developers who take possession of these locations.

description: The present study examines the differential impact of some demographic, socioeconomic and health-related factors on the nutritional status among under-five children in rural Bangladesh using a nationally representative Bangladesh Demographic and Health Survey (BDHS) 2011 data. The BDHS follows a hierarchical data structure because the survey is based on two-stage stratified sampling. Two-level random intercept binary logistic regression models were used to capture the unobserved heterogeneity between clusters (communities) and to identify the determinants of under-five children’s malnutrition. The analyses found that 16% of the children were severely stunted and 26% were moderately stunted. Among the under-five children, 4% were severely wasted and 12% were moderately wasted. Furthermore, 11% of the children were severely underweight and 28% were moderately underweight. The potential factors having significant association with malnutrition were found to be division, child age in month, sex of child, twin child, preceding birth interval, child birth size, religion, mother’s and father’s education, wealth index, household size, age of household head at first child birth, sources of drinking water and suffer from fever and diarrhea. Significant community-level variations were observed in the analyses which emphasis the need for extra attention on the poor performing communities. Specific policy recommendations have been suggested for the improvement of nutritional status of under-five children in rural Bangladesh.

description: The toxicity of copper and nickel was measured in algal cultures of Selenastrum capricornutum and zooplankton cultures of Daphnia magna to determine if dissolved organic carbon (DOC) and/or calcium concentrations can influence toxicity of these two metals. Water samples were collected from the Raisin River (high DOC and high calcium), the St. Lawrence River (low DOC and high calcium), the Ottawa River (medium DOC and calcium) as well as two lakes in Nova Scotia. The concentration sufficient to kill half the population of Daphnia magna after 48h of exposure (LC50), and the inhibition of cell growth of S. capricornutum after 72 h of exposure (IC50) were used to determine the sensitivity of these species to copper or nickel toxicity in these 5 water samples. In Part 3, I showed that the protection against copper or nickel toxicity was reduced with UVB radiation even though the total DOC was reduced by only 18%. The role of EDTA in the toxicity of copper and nickel on S. capricornutum was investigated in part 4. (Abstract shortened by UMI.)

description: Over a decade’s worth of -omics analysis in cutaneous melanoma have revealed that cutaneous melanomas have disparate drug resistance mechanisms to targeted BRAF inhibition. Yet, clinical management of cutaneous melanoma with BRAF inhibitors remains the same for all patients. The lag in clinical adoption of this knowledge can be attributed to the heterogeneity of cutaneous melanoma, where diverse phenotypes make a one-size fits all approach unobtainable. Thus, a precision understanding of how different subtypes of melanoma evades BRAF inhibition will be essential to combat drug resistance. It is widely appreciated that melanocyte differentiation status, which can be determined by gene expression patterns, is a predictor of drug resistance. Here we use this well-described classification system to map the drug resistance mechanisms associated with each subtype. Through computational and genetic screening approaches we revealed revealing common and shared mechanisms of resistances to BRAF inhibition between undifferentiated and differentiated melanomas. Notably we demonstrate that Rac1-signaling as a critical mediator of drug resistance to BRAFi in an inherently drug resistant, de-differentiated, melanoma subtype, and this resistance mechanism is amenable to Src-blockade. To guide the translation of our findings, we also used a machine learning approach to develop a simple classifier to resolve Rac1-dependent melanomas based on a minimal set of genes upregulated in recurrent chromatin states. We demonstrate the prognostic value of this classification system on data from patients undergoing BRAF inhibition or immune checkpoint blockade—finding that subtype assignment tracks with increased resistance to both classes of therapies.

description: The present study examines the impact of non-farm income on poverty and expenditure inequality in rural Bangladesh using a nationally representative Household Income Expenditure Survey (HIES) 2010 data. This study used Horvitz-Thompson (HT) estimator of the Foster, Greer, and Thorbecke (FGT) indices to investigate the effect of non-farm income on poverty. The results reveal that the inclusion of non-farm income reduces the level, depth and severity of poverty in rural Bangladesh. In addition, poverty maps help the policymakers to identify the location of the relatively higher concentration of poor people. However, Gini, Theil’s and Atkinson inequality measures show that the inclusion of non-farm income increased expenditure inequality among rural households. This research also employed a probit model for identifying the most significant factors associated with non-farm income participation of the rural households. The results imply that higher levels of education, greater flow of remittances, availability of electricity facilities and involvement in high return sector are likely to be effective in rising non-farm income at the rural household level. The policy implication of this study is non-farm income generating activities should be encouraged among rural households to reduce poverty and hence, to improve welfare and living standards of the rural households.

description: Cette these vise a preciser les enjeux logiques de la recherche qui mene a la decouverte de nouveaux agirs psychotherapeutiques. Nous procedons d'abord a une recension des ecrits dans le domaine de la philosophie de la technologie, ou les problematiques traitees s'averent particulierement pertinentes. Le consensus le plus important dans ce champ est celui qui porte sur la distinction fondamentale entre la demarche de la technologie d'une part et celle de la science d'autre part, bien que les auteurs different grandement quant a leurs avis respectifs sur la nature des rapports qu'entretiennent science et technologie. Afin de preciser les enjeux logiques sous-jacents, nous proposons un modele de la decouverte des agirs. Notre modele distingue deux types de recherche: la recherche centree-sur-le-savoir et la recherche centree-sur-le-pouvoir. Notre modele met en evidence l'utilisation des connaissances dans le but de generer des agirs et sur l'utilisation des agirs pour generer des connaissances. Nous posons deux facons de concevoir la decouverte d'un agir. La premiere facon consiste a concevoir un agir comme le produit d'une application d'une theorie ou de connaissances scientifiques. La seconde consiste a considerer la genese d'un nouvel agir comme le produit d'un processus de nature inductive. Ce deuxieme cheminement permet de mettre en place des theories technologiques. En nous basant sur ce modele, nous proposons des criteres de demarcation pour repertorier les differents types de recherche, en l'occurrence la recherche scientifique fondamentale, la recherche scientifique appliquee et la recherche technique. Finalement, le modele de la decouverte des agirs est applique a la recherche avec incidence sur la psychotherapie. Suite a une recension des ecrits dans le domaine de la recherche sur la psychotherapie, la recherche actuelle est examinee afin de faire ressortir les enjeux logiques qui lui sont sous-jacents. Les enjeux epistemologiques de la recherche actuelle sont reformules a la lumiere du nouveau modele de la decouverte d'un agir.

description: Background: Urinary calprotectin has been identified as a promising biomarker for acute kidney injury. To date, however, the time-dependent changes of this parameter during acute kidney injury remain elusive. The aim of the present work was to define the time-course of urinary calprotectin secretion after ischaemia/reperfusion-induced kidney injury in comparison to neutrophil gelatinase—associated lipocalin, thereby monitoring the extent of tubular damage in nephron sparing surgery for kidney tumours. Methods: The study population consisted of 42 patients. Thirty-two patients underwent either open or endoscopic nephron sparing surgery for kidney tumours. During the surgery, the renal arterial pedicle was clamped with a median ischaemic time of 13 minutes (interquartile range, 4.5–20.3 minutes) in 26 patients. Ten retro- peritoneoscopic living donor nephrectomy patients and 6 nephron sparing surgery patients in whom the renal artery was not clamped served as controls. Urinary calprotectin and neutrophil gelatinase—associated lipocalin concentrations were repeatedly measured by enzyme-linked immunosorbent assay and assessed according to renal function parameters. Results: Urinary concentrations of calprotectin and neutrophil gelatinase—associated lipocalin increased significantly after ischaemia/reperfusion injury, whereas concentrations remained unchanged after nephron sparing surgery without ischaemia/reperfusion injury and after kidney donation. Calprotectin and neutrophil gelatinase—associated lipocalin levels were significantly increased 2 and 8 hours, respectively, post-ischaemia. Both proteins reached maximal concentrations after 48 hours, followed by a subsequent persistent decrease. Maximal neutrophil gelatinase—associated lipocalin and calprotectin concentrations were 9-fold and 69-fold higher than their respective baseline values. The glomerular filtration rate was only transiently impaired at the first post-operative day after ischaemia/reperfusion injury (p = 0.049). Conclusion: Calprotectin and neutrophil gelatinase—associated lipocalin can be used to monitor clinical and sub-clinical tubular damage after nephron sparing surgery for kidney tumours. Urinary calprotectin concentrations start rising within 2 hours after ischaemia/reperfusion-induced kidney injury.

description: Intellectual disability (ID) is one of the most common neurodevelopmental disorders, affecting 1% of the population globally. Clinically, ID is characterized by a deficit in intellectual functioning and adaptive functioning. There are limited pharmacological interventions for ID, partially due to a poor understanding of ID and the heterogeneous nature of ID In addition, there are limited mouse models of ID.
description: Ciliopathies frequently present with ID. Studying mouse models with genetic mutations for ciliopathies can provide insights into the role of cilia in learning and memory. Cilia are a microtubule-based structure extending from the cell surface, and ciliopathies can have abnormal cilia formation and/or function.
description: The goal of this thesis project is to investigate the role of cilia in behavior using mouse models of the human ciliopathy, Bardet-Biedl Syndrome (BBS). In chapter 2, we investigate the behavioral phenotype of a mouse model with the most common human BBS mutation, Bbs1M390R/M390R mice. The Bbs1M390R/M390R mice have abnormal anxiety-like behavior. In chapter 3, we focus on learning and memory of Bbs1M390R/M390R mice using fear conditioning. Fear conditioning allows us to tease out different aspects of fear memory, and we found that Bbs1M390R/M390R mice have abnormal long-term context fear conditioning, but normal short-term context fear conditioning. This links the ciliary Bbs1 gene to long-term fear memory. In chapter 4, we explore the spatial and temporal role of BBS genes in fear memory. We found that BBS genes in the forebrain, and BBS genes postnatally, play a role in fear context memory.
description: In chapter 5, we investigate neural mechanisms for the fear conditioning impairment in Bbs1M390R/M390R mice. We show that the ciliary BBS genes are important for neural proliferation in the hippocampus. These results indicate a potential therapeutic target. In chapter 6, we demonstrate that an FDA approved drug, Lithium, rescues context fear conditioning, and partially rescues hippocampal neurogenesis.
description: This work provides insight into the role cilia plays in learning and memory. Using a mouse model of BBS, we show that ciliary proteins of BBS play a role in long-term context memory and neurogenesis. In addition, we help outline the spatial and temporal role of BBS genes for long-term context memory. Clinically, our data contribute to the narrative of lithium as a possible treatment for ID.

description: Agriculture-based rural economy of Bangladesh contributes a significant portion to GDP; alleviate poverty and the determining factor for food security. The main obstacle to development of agriculture is the limited supply of land for cultivation, negligence of technology adoption and climate change. Thus, the study was undertaken to make an in-depth review study to fill in the knowledge gap in the way of achievement and challenges in sustainable agriculture production in the country. The study used the secondary information to provide a general view on prospect and challenges of crop sector and suggested necessary measures based on the present analytical review. Cropping intensity increased in the last two decades due to rapid expansion of irrigation, use of fertilizer, crop diversification and a number of policy initiatives by government. Double and triple cropped lands have been increased 37.6% and 273.5% respectively in the last 4 decades. Irrigated area has been increased 4 times in the last 3 decades whereas rice production has been increased 3.33 times in the last 45 years. Low increasing trend of agricultural production attributed to gradual loss of cultivable land, lack of intervention, adoption and dissemination of new technology, lack of sufficient support for agricultural research and training. Technology transfer capacity of extension and research needs to be developed to overcome the present slow and weak research-extension-farmer-market linkage. Agro-ecosystem could be improved using appropriate soil and crop management techniques and enhancing research and extension services and by increasing national and international collaborations.

description: The memories and histories associated with discarded household objects are rebuilt as sculptures that discuss consumer culture, unsustainable materialism, arts accessibility in participatory events, queer world-building, and homemaking through ethical collections and non-archival installations. Raised in a conservative and heteronormative Midwestern home, art became an outlet to explore my own queer identity, gender outside of patriarchal ideals, and the purpose of being an artist as a necessary political critique. I became enamored with structural techniques of welding, woodworking, and metal casting initially because of the similarity to the manual labor associated with my upbringing of spending long hours helping my father after school, my parents’ blue-collar work, and American Midwestern values of hard work and perseverance as humble competency.
description: While returning to Wisconsin after installing one of my sculptures in the spring of 2019, I received a Traumatic Brain Injury from a 13 lb. chunk of concrete. The ordeal necessitated six months of recovery, memory building exercises, and a new eyesight prescription. Thankfully, I was physically fine, but the months of rehabilitation brought on feelings of loneliness and grief over lost memories and a sense of self.
description: Informed by my recovery, my interactive and immersive sculptural installations include Scollages (sculpture + collage) and their shadows, cast metal sculptures of deteriorated fabric comforts, surreal false spaces, double-exposed cyanotype prints of refashioned architecture, distorted home decor, video projection, and stacked assemblages of furniture that call attention to the ephemeral and visceral qualities of memory, challenge ideas of social class systems, the inherent purpose of objects, and the irreverence for labor and everyday commodities. Personal experience and my own memories are the foundation for creating community-engaged events as shared experiences of art outside of current capitalist social structures. Deconstructed household goods are rebuilt in site-specific installations to reclaim femme-engendered objects and societally gate-kept roles. The reconstructed work takes on imagined function and purpose in uncanny spaces, creating embodied experiences within each installation. The haunting differences yet familiar closeness of the staged installation sets become potential sites for queer homemaking and storytelling as world-building beyond American capitalistic systems of societal value.

description: Peak fingertip blood lactate values obtained following maximal intensity simulated double poling ski exercise (PBLa(A)), were compared with peak fingertip blood lactate values obtained following maximal intensity simulated combined arm and leg ski striding exercise (PBLa(A + L)). The combined arm and leg protocols were performed on two different types of treadmills, a walking treadmill and a ski treadmill. Phase one combined arms and legs ski striding protocol (A + L)$\sb1$, involved ski walking on a treadmill with simultaneous arm poling movements achieved through a rope pulley system. Phase two combined arms and legs ski striding protocol (A + L)$\sb2$, whereby skiers using skis and poles performed a diagonal stride on a carpeted treadmill. The arms only double poling exercise protocol(A), was conducted identically in both test phases. Kneeling on a trolley or rollerboard, skiers pulled themselves up a 95 inch inclined track using rope pulleys at a cadence of one pull every 2.5 seconds. Peak blood lactate values represented the highest blood lactate value obtained from the post exercise samples. Differences in phase one and two PBLa(A + L) and MVO$\sb2$ values were related to the degree of sports specificity of the A + L protocol to cross-country skiing. (Abstract shortened by UMI.)

description: The study attempted to examine farmers’ attitudes towards rice production and also to identify factors influencing the attitudes. A total of 100 rice producers were selected purposively from four unions of Phulpur Upazila under Mymensingh district. Data were collected from mid-September to mid-October 2017 through face to face interview method. Five point Likert scale was used to examine farmers’ attitudes towards rice production. A multiple regression model was used to examine whether there are influencing factors (socio-economic characteristics) on the farmers’ attitudes towards rice production. By using the Likert scale, total score value for individual farmers was calculated and it was found that most of the farmers’ (98 percent) attitudes towards rice production were favored; and only 2 percent were un-favored attitudes towards rice production in the study area. Average score value for the individual statements were also estimated and found that score value was less than three for only three statements out of 20 statements, it also proved that most of the cases (85 per cent) farmer’s attitudes were favored towards rice production. The study found that level of education, occupation and farm size had significant influences on the farmers’ attitudes towards rice production.

description: This study examines the effectiveness of groundwater service providers of Bogura and Chapainawabgonj districts in Northwest Bangladesh by employing qualitative approach. Required data were collected through focus group discussions, key informant interviews, in-depth interviews, case studies, and observation from purposively selected participants, and analyzed through qualitative content analysis. Findings reveal that though majority of the farmers are dependent on institutional groundwater service providers, namely Barind Multipurpose Development Authority, Bangladesh Agriculture Development Corporation, and Rural Development Academy for groundwater irrigation, the share of individual tube-well owners is increasing noticeably. Provider specific effectiveness was assessed based on managerial, operation, and economic efficiencies. It is found that water buyers mostly prefer individually owned tube-wells for irrigation instead of institutional providers. Good service delivery, good operational and managerial practices, comparatively low irrigation charges, and regular water supply are the important factors motivated water buyers to choose individual service providers over institutional providers.

Telemedicine

description: Burnout prevalence rates have been notably increasing, and leading members of the healthcare community began to call for change in 2019. Immediately following this call for action, the COVID-19 pandemic drastically changed the workflows and demands for healthcare providers. This study aims to assess the prevalence of burnout in the telemedicine healthcare community, and better understand how the growing use of telemedicine can impact workplace stress.
description: Providers in urgent care clinics were invited to participate in a survey. The survey captured demographic information and assessed burnout using the Maslach Burnout Inventory (n = 32). Correlation analyses were conducted on participant demographics and burnout dimension scores. Follow-up interviews were conducted with a subset of providers (n = 9) who participated in the survey. Follow-up interviews provided insights on the contributing and mediating factors of telemedicine in provider burnout. These findings were organized using the Job Demands- Resources framework. Insights from the interviews were compared to findings from literature to identify any overlaps and/or gaps in the general perceptions of telemedicine, as well as inform future research efforts.
description: The findings from this study provide technology- and organizational-level recommendations to protect providers using telemedicine from increased risk of burnout. The contributing and mediating factors identified and categorized in this study also provide a framework to understand the risks telemedicine can pose on workplace well-being. Future research recommendations include the need for more mixed methods studies, providing not only qualitative insights on burnout dimensions, but also better quantification of burnout dimensions to effectively design intervention and implementation strategies.
Undergraduate learners’ prior knowledge in an Introductory astronomy course

description: When a student first attends a university level course, they often enter with a certain amount of prior knowledge on the topics of the course. This prior knowledge can be in the form of facts, beliefs, concepts, values, or attitudes and will impact the way that student processes new information. To ensure every individual is processing new information correctly, it is important for instructors and mentors to address their learners' prior knowledge and guide them in the correct direction if they possess an inaccurate conception. For undergraduate learners in an introductory astronomy course, the cause of the phases of the Moon is a fundamental concept they should have some prior knowledge on from middle or high school. This case study was designed to investigate how undergraduate learners' prior knowledge on the causes of the phases of the Moon has evolved throughout a portion of a semester based on formal instruction of the topic. For this study formal instruction included lectures on the lunar phases and a lab that was designed to target common conceptions learners possess about the phases of the Moon. To assess the learners' prior knowledge before and after instruction, a survey with free response questions pertaining to the Moon was administered. The results from the two surveys show that formal instruction has a positive impact upon the learners' prior knowledge and designing activities based on common conceptions around the phases of the Moon helped learners transition from these common conceptions to more scientific ones.

description: Data collected during the 2012 Ebola virus disease (EVD) epidemic in the Democratic Republic of the Congo were analysed for clinical signs, symptoms and case fatality of EVD caused by Bundibugyo virus (BDBV), establishment of differential diagnoses, description of medical treatment and evaluation of the quality of clinical documentation. In a quantitative observational prospective study, global epidemiological data from 52 patients (34 patients within the community, 18 patients treated in the Ebola Treatment Centre) were entered anonymously into a database, subsequently matched and analysed. Relevant findings include an over-representation of females among community EVD cases (85.3%) and of community EVD cases in the age group of 15-54 years (82.4%). All ETC patients had fever (55.6% of all 18 ETC patients during their hospital stay) or self-reported fever (88.2% upon admission) at some point of time during their illness. Major symptoms of ETC patients during hospital stay included asthenia (82.4%), anorexia (82.4%), myalgia (70.6%), sore throat/difficulty swallowing (70.6%), arthralgia (76.5%) and nausea (70.6%). Gastrointestinal signs and symptoms (nausea, diarrhoea, vomiting) (76.4%) as well as general pain (94.1%) were frequent in ETC patients. The median duration of EVD was 18 days, while the mean incubation period was 11.3 days. Differential diagnosis of EVD included malaria (28.3%), intestinal parasitosis (10.9%), and infectious syndrome (10.9%). There was also an important variation in clinical evolvement. Quality of documentation was adversely affected by the way patient file contents were transferred from inside to outside the high-risk zone, entailing a mean mismatch value of 27.3% between patient file contents inside vs. outside the high-risk zone. This study adds further description of EVD (frequently non-specific signs and symptoms, non frequent bleeding, a long incubation period, long duration of disease) and emphasizes the need for improving clinical monitoring and documentation in EVD outbreak settings.

description: Purpose: To explore potential design for pharmacogenomics trials in sepsis, we investigate the interaction between pharmacogenomic biomarkers and response to drotrecogin alfa (activated) (DrotAA). This trial was designed to validate whether previously identified improved response polymorphisms (IRPs A and B) were associated with an improved response to DrotAA in severe sepsis. Methods: Patients with severe sepsis at high risk of death, who received DrotAA or not, with DNA available were included and matched to controls adjusting for age, APACHE II or SAPS II, organ dysfunction, ventilation, medical/surgical status, infection site, and propensity score (probability that a patient would have received DrotAA given their baseline characteristics). Independent genotyping and two-phase data transfer mitigated bias. The primary analysis compared the effect of DrotAA in IRP+ and IRP− groups on in-hospital 28-day mortality. Secondary endpoints included time to death in hospital; intensive care unit (ICU)-, hospital-, and ventilator-free days; and overall DrotAA treatment effect on mortality. Results: Six hundred and ninety-two patients treated with DrotAA were successfully matched to 1935 patients not treated with DrotAA. Genotyping was successful for 639 (DrotAA) and 1684 (nonDrotAA) matched patients. The primary hypothesis of a genotype-by-treatment interaction (assessed by conditional logistic regression analysis) was not significant (P = 0.30 IRP A; P = 0.78 IRP B), and there was no significant genotype by treatment interaction for any secondary endpoint. Conclusions: Neither IRP A nor IRP B predicted differential response to DrotAA on in-hospital 28-day mortality. ClinicalTrials.gov registration NCT01486524

description: The study determined the economics of traditional cassava processing technology among small-holder female cassava processors in delta North Agricultural Zone, Delta State Nigeria. Multi-stage sampling procedure was used to select 60 cassava processors in the study area. Qualitative and quantitative techniques were used to analyze the information obtained from the questionnaire survey. To determine the profitability of traditional cassava processing among female cassava processors in the study area, average of 5,000kg of cassava tubers was measured and used per processors within the year under study. The result also indicated that the processors were well experienced (mean experience of 24.70 years) and were low income earners with a mean income of =N=333,383 ($952.52). The findings also revealed that the variable cost components constituted the major cost components the by-products obtained. The result also indicated that garri, starch, akpu and abacha were the main products obtained from processing cassava and that garri/starch was the most profitable by-product of cassava with a net profit of N 71,191.50 ($203.44) followed byakpu N 48,832 ($139.55) and abcha N 60,452 ($172.73) respectively. The return on investment indicated that traditional cassava processing technology in the study area was profitable. Based on the finding of the study, it was recommended that traditional cassava processors in the study area should form co-operation societies pull their resources together in other to enjoy the benefits of economics of scale as well as benefits arising from government programmes. It also recommended that government-private sector intervention should be encouraged. Public enlightenment campaign on the profitability of cassava processing also recommended to be carried out.

public abstract

description: The interest in applying machine learning to answer astrophysical problems has risen dramatically in recent years, driven in large part by a desire to classify systems for more detailed studies of their intrinsic properties. One of the long outstanding problems in astronomy has been the origin of spiral structure in galaxies. While numerous theories have been proposed over the years, none has been convincingly proven. Machine learning holds considerable promise to resolve the long standing spiral problem by providing a means to model spiral arm properties in a much more detailed and automated way than has currently been possible, allowing for more direct comparisons between observations and theory over a large sample of galaxies. In this thesis I take a deep learning approach towards building a tool for automating the identification of spiral arms in galaxies through the use of a recurrent convolutional neural network. Compared to most deep learning tasks, identifying spiral arms pose a considerable problem due to their long, winding nature. To aid the network we utilize well known physical insights to spatially transform the image to make it easier for segmenting the individual arms. Given an image of a galaxy, the network outputs a series of spiral arm masks with an associated probability that the mask represents a spiral arm. Tests on synthetic galaxies reveals that we are able to reliably detect spiral arms with a precision approaching 100% whose average signal-to-noise ratio is greater than S/N > 1/3 and whose arm contrast is greater than 10% of the underlying galaxy flux.
