After the Project is Over: Measuring Longer-Term Impacts of a Food Safety Intervention in SenegalLaura Elizabeth Leavens (9183350) 30 July 2020 (has links)
<p>We followed up with about 2,000 smallholder households in Senegal, two years after these households participated in a randomized controlled trial (RCT) aimed at reducing levels of aflatoxins in smallholders’ stored maize. In the initial intervention, treated households were provided with training on proper post-harvest practices, low-cost moisture meters for testing if maize was sufficiently dry to store, plastic tarps for drying maize of the ground, and hermetic (airtight) storage bags to mitigate aflatoxin development in stored maize. Using cross-sectional follow up data on aflatoxins levels and drying and storage practices from 2019 along with baseline demographic data from 2016, we estimate both the longer-term intention-to-treat (ITT) effects and the treatment on the treated (TOT) effects that the four inputs provided on households’ aflatoxins levels in stored maize. The ITT analyses estimate the intervention’s average effect by treatment group, but this may underestimate the true impact for households who complied with recommended post-harvest practices and adopted the recommended technologies. The TOT analyses estimate the local average treatment effects (LATE) of the intervention, that is its impacts on those who were driven by the intervention to follow best practices or use a given technology. Since the decision to follow these practices or adopt a technology was not random, we instrumented the usage decision with the exogenous, random treatment group assignment to get an unbiased estimate. Outside of our main models, we conducted a heterogeneity analysis to test if households with different characteristics benefit differently from the intervention. We interacted each treatment assignment with various household characteristics, including the woman’s level of involvement in the intervention. Additionally, we estimate the cost-effectiveness of providing training and a tarp, according to WHO guidelines for public health interventions. </p>

Examensarbete i industriell teknik vid Scania R&D / Degree project in industrial technology and management at Scania R&DLöfholm, Birgitta January 2020 (has links)
The study aims to study if it is possible to reduce lead time or resource needs by studying the PD process, Product Development Process linked to the improvement area Unclear requirements from managers on measuring the process. This is done by studying current control, the possibility of using other measuring points and how a measurement system could be established, including Scorecard within Scania R&D, Research and Development. The study is based on the questions What does the product development process look like? What could be measured in the product development process? and How could a measurement system with integrated Scorecard be implemented for better control of the product development process? Theories include the areas of processes, process control, process measurement and process management. Interviews, group interviews, document studies, literature studies and previous research were the basis for studying the problem and opportunities for improvement. All data collection was done remotely as Covid-19 had major impacts. The result of the study shows that R&D does not currently measure the PD process, but measurement is regulated in internal documents. Measurement of lead time, resources and costs was desired by interviewees to measure. Basing the measurement on the current KPI, Key Performance Indicators, and R&D strategic plan 2020 implies established support from the functions that produced the internal documents. The developed measurement system includes the measurement points lead time, cost and resource requirements as well as selected milestones. An introduction of the measurement system would, for Scania R&D, provide an opportunity to control the PD process linked to the measurement points. The measurement system has largely been based on internal documents to increase the relevance of the measurement system and the possibility of an introduction. / Studien syftar till att studera om det går att minska ledtid eller resursbehov genom att studera PD processen, Product Development Process, kopplat till förbättringsområdet Otydliga krav från chefer på mätning av processen. Det utförs genom att studera nuvarande styrning, möjligheten att använda andra mätpunkter samt hur ett mätsystem skulle kunna upprättas inkluderat Scorecard inom Scania R&D, Research and Development. Studien baserar sig på frågeställningarna Hur ser produktframtagningsprocessen ut? Vad skulle kunna mätas i produktframtagningsprocessen? samt Hur skulle ett mätsystem med integrerat Scorecard kunna implementeras för bättre styrning av produktframtagningsprocessen? Teorier berör områdena processer, processtyrning, processmätning och processledning. Intervjuer, gruppintervju, dokumentstudier, litteraturstudier och tidigare forskning låg till grund för att studera problemet och förbättringsmöjligheter. Samtlig datainsamling utfördes på distans då Covid-19 hade stora påverkningar. Studiens resultat visar att R&D i nuläget inte mäter PD processen men mätning finns reglerat i interna dokument. Mätning av ledtid, resurser och kostnader var önskat av intervjupersoner att mäta. Att basera mätningen på nuvarande KPI, Key Performance Indicators, och R&D strategisk plan 2020 innebär ett etablerat stöd hos de funktioner som tagit fram de interna dokumenten. Det framtagna mätsystemet inkluderar mätpunkterna ledtid, kostnad och resursbehov samt utvalda milstolpar. Ett införande av mätsystemet skulle för Scania R&D innebära en möjlighet till att styra PD processen kopplat till mätpunkterna. Mätsystemet har till stor del baserats på interna dokument för att öka mätsystemets relevans samt möjligheten till ett införande.

Path Planning and Path Following for an Autonomous GPR Survey RobotMeedendorp, Maurice January 2022 (has links)
Ground Penetrating Radar (GPR) is a tool for mapping the subsurface in a non-invasive way. GPR surveys are currently carried out manually; a time-consuming, tedious and sometimes dangerous task. This report presents the high-level software components for an autonomous unmanned ground vehicle to conduct GPR surveys. The hardware system is a four-wheel drive, skid steering, battery operated vehicle with integrated GPR equipment. Autonomous surveys are conducted using lidar-inertial odometry with robust path planning, path following and obstacle avoidance capabilities. Evaluation shows that the vehicle is able to autonomously execute a planned survey with high accuracy and stops before collisions occur. This system enables high-frequency surveys to monitor the evolution of an area over time, allows one operator to monitor multiple surveys at once, and facilitates future research into novel survey patterns that are difficult to follow manually

”Bra fråga, jättebra fråga…” : En kvalitativ studie av en lärares uppföljningar för stöttning i ett flerspråkigt klassrum. / ”Good question, very good question” : A qualitative study of a teacher’s follow-ups for support in a multilingual classroom.Linda, Julien January 2022 (has links)
Syftet med föreliggande studie är att undersöka om och isåfall hur lärare på språkintroduktionsprogrammet i sin undervisning stöttar flerspråkiga elevers interaktion på målspråket genom uppföljningar. Metoden för studien grundar sig i två modeller: Exchange Structure Model av Sinclair & Coulthard (1975) och interaktionell stöttning av Hammond & Gibbons (2005). Data samlades in i form av ljudinspelningar och klassrumsobservationer på språkintroduktionsprogrammet. Resultatet visar att läraren i interaktionen med flerspråkiga elever med begränsade språkliga kunskaper använder sig av stöttande drag genom kopplingar till tidigare erfarenheter, sammanfattningar, metakommentar, approprieringar, omformuleringar, antydande eliciteringar och framåtriktningar. Undersökningens slutsatser är att uppföljningar kan stötta interaktionen på målspråket och att det kan vara viktigt att läraren för det flerspråkiga klassrummet hittar ett innehåll som är intresseväckade för eleverna.

Suivi photométrique de candidates exoplanètes identifiées par le Transiting Exoplanet Survey SatelliteCadieux, Charles 08 1900 (has links)
La majorité des exoplanètes connues à ce jour ont été découvertes par la méthode du transit, qui infère indirectement l’existence de tels objets, si l’alignement le permet, en mesurant la baisse temporaire et répétée de la brillance d’une étoile lors du passage d’une exoplanète devant celle-ci. La recherche de biosignatures, donc de vie, dans l’atmosphère d’une exoplanète est désormais le principal objectif dans ce domaine d’études, et pour maintes raisons, celles de taille de moins d’approximativement deux rayons terrestres autour d’étoiles naines rouges sont particulièrement convoitées. Afin de connaître davantage de tels systèmes dans le voisinage solaire et dans toutes les régions du ciel, le Transiting Exoplanet Survey Satellite (TESS) fut lancé en avril 2018. Le grand échantillonnage de 21'' par pixel des caméras à bord de TESS résulte fréquemment à une contamination des données des étoiles d’intérêt montrant un signal prometteur de transit, par le flux d’autres étoiles à proximité. Lorsque l’une de ces sources contaminantes est une étoile binaire à éclipses, phénomène astrophysique pouvant mimer un transit, la détection constitue très souvent un événement faux positif. Ainsi, de nouvelles observations photométriques et spectroscopiques sont généralement requises pour identifier les véritables exoplanètes. Ce mémoire présente les résultats du suivi photométrique de neuf candidates exoplanètes identifiées par TESS à l’Observatoire du Mont-Mégantic avec la caméra Planètes Extra-Solaires en Transit et Occultations (PESTO). Une routine d’ajustement de courbe de transit développée durant cette maîtrise procure une estimation de certains paramètres physiques (rayons, demi-grand axe et inclinaison) des candidates. Parmi celles-ci, TOI 1452.01 ressort du lot, car cette probable exoplanète d’environ deux rayons terrestres orbite dans la zone habitable de son hôte naine rouge, c’est-à-dire à une distance permettant la présence d’eau liquide à sa surface. / The majority of the exoplanets known to date have been discovered using the transit method, which indirectly infers the existence of such objects by measuring a temporary and repeated drop in the brightness of a star when, for the right alignement, an exoplanet passes in front of it. The search for biosignatures, thus life, in an exoplanet atmosphere is now the main objective in this field of study, and for several reasons, planets with a radius less than approximately two Earth radii around red dwarfs are particularly targeted. With the goal of finding more such systems in the solar neighbourhood and in all regions of the sky, the Transiting Exoplanet Survey Satellite (TESS) was launched in April 2018. The large image sampling of 21'' per pixel of the cameras on board TESS often results in data contamination of stars showing promising transit signal, by the flux of nearby stars. If one of these contaminating sources happens to be an eclipsing binary, an astrophysical phenomenon able to mimic a transit, the detection is most likely a false positive event. Thus, follow-up observations in photometry and in spectroscopy are generally required to identify the genuine exoplanets. This thesis presents the results of a photometric monitoring campaign at the Observatoire du Mont-Mégantic with the Planètes Extra-Solaires en Transit et Occultations (PESTO) camera of nine exoplanet candidates identified by TESS. A transit curve fitting routine developed during this master’s provides an estimation for certain physical parameters (radius, semi-major axis and inclination) of these candidates. Among them, TOI 1452.01 stands out, because this probable exoplanet has an estimated radius close to two Earth radii, in addition to being located within the habitable zone of its red dwarf host, i.e. at a distance allowing the presence of liquid water on its surface.

Intensivvårdsbehandlade patienters upplevelser av efterförloppet : En litteraturstudie / Patients´ Experiences of Recovery after Intensive Care Treatment : A literature reviewBengtsson, Jennie, Kristiansson, Karolina January 2021 (has links)
Bakgrund: Utvecklingen av intensivvården har under de senaste åren lett till att antalet personer som överlever intensivvården har ökat. Över hälften av alla överlevare drabbas av olika komplikationer i efterförloppet som kräver behandling och rehabilitering. Kunskapen om detta är av betydelse för sjuksköterskan för att förstå vikten av personcentrerad vård efter intensivvårdsbehandling. Syfte: Syftet med litteraturstudien var att sammanställa intensivvårdsbehandlade patienters upplevelser av efterförloppet. Metod: En kvalitativ litteraturstudie med induktivt förhållningssätt. Databaserna PubMed, Cinahl och SveMed+ användes för att ta fram material för studien. En kvalitetsgranskning av studierna utfördes med SBU:s granskningsmall för kvalitativa studier. Resultat: Resultatet redovisas utifrån sex kategorier: fysisk, psykisk och kognitiv påverkan, en lång återhämtningsprocess, behov av stöd från närstående, behov av omvårdnad, behov av hanteringsstrategier och förändringar av livet. Konklusion: Studiens resultat skildrar de intensivvårdsbehandlade patienternas olika upplevelser i efterförloppet. Patienterna upplevde att deras behov inte blev tillgodosedda samt att tillgången till och kvaliteten på den uppföljande vården var begränsad. De upplevde även en brist på information om vad tiden efter intensivvårdsbehandlingen skulle innebära. Den uppföljande vården har utvecklats under den senaste tiden, men behöver fortsatt utveckling för att kunna tillgodose behoven hos denna patientgrupp. / Background: The development of intensive care during the latest years have led to increasing numbers of ICU survivors. More than half of all survivors are affected by different complications after intensive care treatment that needs treatment and rehabilitation. This knowledge is of meaning for the nurse to understand the importance of person-centred care after intensive care treatment. Aim: The aim of the study was to compile patients’ experiences of recovery after intensive care treatment. Method: A literature review with a qualitative approach was used. Literature searches were performed in the databases PubMed, Cinahl and SveMed+. The quality of the selected studies was assessed using SBU’s review tamplet for qualitative studies. Results: The results are reported based on six categories: physical, mental, and cognitive impact, a long recovery-process, need for support from family and friends, need for care, need for coping strategies and changes in life. Conclusion: The results of the study describes the patients´ different experiences during the recovery from intensive care treatment. The patients experienced that their needs weren´t fullfilled and that the availability and quality of the follow-up care was limited. They also experienced that there was a lack of information about the recovery. The follow-up care has developed during the recent years, but it needs further development to be able to meet the needs of this group of patients.

Mimésis - imitatio v autentických Pavlových listech / The Mimesis - Imitatio in the autentic Letters of PaulMátiková, Anna January 2013 (has links)
Mimesis - Imitatio in the Authentic Letters of the Apostle Paul The first part of the thesis provides the reader with a concise overview of different semantic levels of the term mimesis as found in the ancient literature written in the Greek language. Furthermore, the author focuses her attention on the use of the concept of mimesis in the Old Testament, and the New Testament writings other than Paul's authentic letters. Such a survey prepares the ground for a detailed study of the concept of mimesis in the authentic letters written by the Apostle Paul. The idea of mimesis is present in Paul's authentic letters in five explicit passages (1 Tess 1:6-7; 1 Tess 2:14; 1 Cor 4:16; 1 Cor 11:1 a Phil 3:17). Each of the passages is studied within the whole context of the respective letter, written for a group living its own particular situation. The thesis compares different exegetical solutions from several researchers. Some of the researchers understand Paul's appeal to imitation as a call to be obedient to his teaching. Other experts are more inclined to understand this imitation as an authentic representation of the Cross in the life of Jesus' followers. The thesis tries to prove that the mystery of Christ's kenosis, expressed in a very significant way in the Christological hymn contained in the Letter to the...

Riskfaktorer för kvarvarande symtom post-covid-19 : En uppföljningsstudie på sex månader efter utskrivning från sjukhus / Risk factors for persistent symptoms post covid-19 : A follow-up study of six months after discharge from hospitalSarenmalm, Emelie January 2022 (has links)
Bakgrund: I början av december 2019 kom de första rapporterna om viruset Severe Acute Respiratory Syndrome Coronavirus 2 som orsakar sjukdomen Coronavirus Disease 2019 (covid-19). Många som genomgått en covid-19-infektion får långvariga besvär. Syfte: Syftet var att undersöka eventuella samband mellan riskfaktorer och kvarvarande symtom efter genomgången covid-19 upp till sex månader efter utskrivning från sjukhus. Metod: Studien är en icke-experimentell prospektiv longitudinell kohortstudie. Kohorten består av 37 patienter som vårdades på ett sjukhus i Västra Götaland för covid-19 under perioden juni 2020 till februari 2021. Potentiella riskfaktorer, biomarkörer och infektionsparametrar under sjukhusvistelsen analyserades tillsammans med patienternas självskattade upplevelse av symtom enligt skalan Post Covid-19 Functional Status (PCFS), vid en, tre och sex månader efter genomgången covid-19. Resultat: Resultatet av analysen visade signifikanta relationer mellan rökning (p=.018), sekundära diagnoser under vårdtiden (p=.003), en ålder >65 år (p=.014) samt att ha en cancerdiagnos (p=.046) och att rapportera kvarvarande symtom som påverkar vardagen. Trötthet och nedsatt ork var de vanligast rapporterade symtomen post-covid, följt av andningsrelaterade besvär. Vid sex månaders uppföljning rapporterar 62% ett eller flera kvarvarande symtom. Slutsats: Då detta är en liten studie kan inga säkra slutsatser dras från analysen. Studien visar dock att det finns anledning till oro angående de långsiktiga konsekvenserna av covid-19. / Background: In early December 2019, reports came about the Severe Acute Respiratory Syndrome Coronavirus 2 causing Coronavirus Disease 2019 (COVID-19). Many who have gone through COVID-19 get long-term symptoms. Aim: The aim was to investigate possible links between risk factors and persisting symptoms after having COVID-19, up to six months after discharge from hospital. Method: The study is a non-experimental prospective longitudinal cohort study. Included were 37 patients who were treated for COVID-19 at a Swedish hospital between June 2020 and February 2021. Potential risk factors, biomarkers and vital signs during the hospital stay were analyzed together with patients' self-assessed experience of symptoms and functionality according to Post COVID-19 Functional Status (PCFS), up to six months after having COVID-19. Results: Significant relationships are shown between smoking (p = .018), secondary diagnoses during the hospital stay (p = .003), age> 65 years (p = .014) and having a cancer diagnosis (p = .046) and to report persistent symptoms that affect daily life. Fatigue was the most commonly reported symptom, followed by respiratory symptoms. At the six-month follow-up, 62% of patients report one or more remaining symptoms. Conclusion: As this was a small scale study, no definite conclusions can be drawn from the analysis. However, the study shows that there is cause for concern regarding the long term consequences of COVID-19. / <p>Program: - (fristående kurs) </p>
