Behavioral skills training (BST) has been widely used to effectively and quickly instruct learners with limited knowledge in behavior analytic skills. A training package composed of didactic instruction presented via PowerPoint, modeling, rehearsal, feedback and in vivo components were utilized to instruct two mothers of children with autism spectrum disorders to deliver learning trials with their child to contrive MOs to increase their manding repertoires. A multiple probe across participants design was used to assess the effects of BST on the participant's performance. Prior to the beginning of the study, participants were instructed to systematically identify child's reinforcers by delivering a paired choice preference assessment. Mothers were involved in choosing the manding targets used in the child's instruction. BST was effective in demonstrating rapid acquisition of skills taught to both mothers compared to baseline performances. Although child's behavior increased over pretest measures, it did not improve significantly due variable responding. Time constraints and child's excessive variable responding lead to termination of the study.

The study of the angular distribution of photon plus jet events in pp collisions at √S =7 TeV with the Compact Muon Solenoid (CMS) detector is presented. The photon is restricted to the central region of the detector (|η| < 1.4442) while the jet is allowed to be present in both central and forward regions of CMS |η| < 2.4). Dominant backgrounds due to jets fragmenting into neutral mesons are accounted for through the use of a template method that discriminates between signal and background. The angular distribution, |η*|, is defined as the absolute value of the difference in η between the leading photon and leading jet in an event divided by two. The angular distribution ranging from 0-1.4 was examined and compared with next-to-leading order QCD predictions and was found to be in good agreement.

Abstract Mål: Syftet med denna studie var att kartlägga farmaceuters upplevelser kring huruvida en frågelista (Question Prompt List, QPL) är ett användbart verktyg för att öka kommunikationen och patientaktiveringen på svenska öppenvårdsapotek. Kommunikationen på öppenvårdsapotek bör förbättras så patienter får optimal läkemedelsanvändning. Metod: Kvalitativa semistrukturerade intervjuer genomfördes med 27 farmaceuter och två apotekarstudenter på sju olika öppenvårdsapotek i Stockholm, Uppsala och Göteborg under hösten 2020. Respondenterna bestod av 24 kvinnor och fem män som hade använt QPL:en i sitt arbete under 1-2 veckor. Intervjuerna varade mellan 6-47 minuter, median 15 minuter. Dessa transkriberades och analyserades via systematisk textkondensering (STC). Resultat: Efter STC identifierades fyra resultatkategorier; 1. Ett kommunikationsverktyg som får farmaceuterna att tänka till om sina kundmöten, 2. QPL:en var en tankeställare som kan bjuda in till samtal samt tända en och annan glödlampa hos kunderna, 3. En användbar inbjudande lista med förbättringspotential för att underlätta ytterligare för kunderna på apoteken, 4. Det är viktigt att möta och fånga upp kunden för att kunna ge den bästa servicen. Majoriteten av farmaceuterna (n=28) kan tänka sig använda QPL:en i framtiden. Tidsbrist gjorde att listan inte var användbar i alla kundmöten. QPL:en ansågs ha utvecklingspotential och farmaceuterna gav förslag på hur kommunikation på öppenvårdsapotek kan optimeras; genom exempelvis ökat engagemang från farmaceuternas sida. Slutsats: Farmaceuterna upplevde att QPL:en var användbar och fick kunderna att fråga mer, men inte vid alla kundmöten. QPL:en kan optimeras ytterligare och göras mer lättläslig. Kommunikationen på öppenvårdsapotek bör optimeras ytterligare.

<p>Secondary atomization is very important in applications like IC engine and aircraft engine performance, agricultural sprays, and inkjet printing to name a few. In case of IC engines and aircraft engines, a good understanding of the modes of secondary atomization and the resultant drop size can contribute to improving the fuel injection and hence the efficiency of the engine. Similarly, with the help of appropriate secondary atomization desired agro-spray quality, ink usage and print quality can be achieved which would optimize the usage of chemicals and ink respectively and avoid any harmful effects on the environment.</p> <p> </p> <p>One of the reasons for secondary atomization that occurs very often in most of the spray applications is the drop impact on a solid or liquid surface. Especially it is cardinal to understand the impact of a drop on a liquid film since even in case of impact of liquid drops on a solid surface ultimately the drops that are injected at a later time are going have a target surface as a thin liquid film on the solid base due to the accumulation of the previously injected drops. Analysis of drop impact on a liquid film with non-dimensional thickness ranging from 0.1 to 1 has been done thoroughly before (Cossali <i>et al.,</i> 2004, Vander Waal <i>et al.,</i> 2006, Moreira <i>et al.,</i> 2010), however, analysis of drop impact on a liquid film with non-dimensional thickness greater than 1 is still in a rudimentary stage. This work focuses on determining the probability density functions for the secondary drop sizes for drops produced in case of drop impact on a liquid film while varying the h/d ratio beyond 1. The experimental set-up used to study drop impact includes a droplet generator and DIH system as mentioned in, Yao <i>et al.</i> (2017). The DIH set-up includes a CW laser, spatial filter, beam expander and a collimator as adapted from Guildenbecher <i>et al.</i> (2016). The height of drop impact is varied to vary the impact <i>We</i>, by adjusting the syringe height. Three fluids- DI-Water, ethanol and glycerol are tested for examining the effect of viscosity on the resultant drop sizes. Results are plotted with respect to viscosity, impact <i>We</i> and the non-dimensional film thickness, as the fragmentation of drops is directly associated to these parameters. Results indicate that majority of the secondary droplets lie in the size range of 25 µm to 50 µm. It is also observed that the tendency of secondary atomization from crown splashing increases with the increase in <i>We</i> and decreases with increase in <i>Oh.</i></p>

Prompt dependence can be a serious problem for individuals diagnosed with autism spectrum disorder or intellectual disabilities. The ability to perform skills independently is important for a high-quality life and assimilation in the community among many other things. Assessments of instructional strategies may be an effective tool for identifying instructional strategies that decrease one’s reliance on prompts. An alternating treatment design was used to evaluate the effectiveness of an assessment of instructional strategies on independent responses during auditory-visual discrimination tasks. Assessment conditions included positional prompt, gestural prompt, physical prompt, and identity matching to sample. The most effective instructional strategy was identified as the strategy that corresponded to quickest acquisition of independent responses. Results of the assessment demonstrated differences in individual learning patterns for each of the 3 participants. However, the differences observed in the assessment among instructional strategies were not significant. Implications of these results do suggest to educators that conducting an assessment of instructional strategies may be a useful strategy for identifying differences in learning patterns. Limitations and directions for future research are also discussed.

Prompt engineering is the craft of designing prompts in order to get desired answers from language models such as ChatGPT. This thesis investigates how ChatGPT, specifically GPT-4, can be used to detect plagiarism in simple programming exercises. We used a dataset containing seven different original solutions for programming tasks. Every programming task also contained solutions that were plagiarizing the original as well as solutions that did not plagiarize the original. After testing various different prompts on a subset of the dataset, four different prompts were tested on the majority of the dataset. Three of the prompts produced unreliable results to the point that simply guessing whether or not the task solutions were plagiarized would have frequently been more accurate. The fourth prompt was more accurate although still not accurate enough for it to be recommended to use ChatGPT in order to identify plagiarism. / Promptkonstruktion (prompt engineering) är konsten att skapa instruktioner som ger bästa möjliga svar från språkmodeller (language models) såsom ChatGPT. Denna avhandling undersöker hur ChatGPT kan användas för att upptäcka plagiat i enkla programmeringsuppgifter. Vi använde ett dataset som innehåller sju olika originallösningar på enkla programmeringsuppgifter. Varje programmeringsuppgift har plagierade lösningar som löser samma uppgift och icke-plagierade lösningar som också löser samma uppgift. Efter att ha testat olika instruktioner med ChatGPT på en liten delmängd av datasetet, testades fyra olika instruktioner på majoriteten av datasetet. Tre av instruktionerna gav opålitliga resultat till den grad att det ofta skulle gett ett bättre resultat att gissa om lösningarna var plagierade eller inte. Den fjärde instruktionen gav bättre resultat, men fortfarande inte tillräckligt bra för att rekommendera att använda ChatGPT för att identifiera plagiat.

Das Prompt Gamma-Ray Timing (PGT) ist eine vielversprechende Methode für die in vivo Reichweite-Verifikation in der Protonentherapie. Dabei wird mit unkollimierten Szintillationsdetektoren die Zeit-Verteilung prompter Gammastrahlung, in der die Protonenreichweite enthalten ist, gemessen. In dieser Arbeit wurden PGT-Spektren einer Bestrahlung eines Plastikphantoms mit verschiedenen Dicken an Luftkavitäten analysiert. Neben der Optimierung der Datenverarbeitung wurden Methoden für die Selektion statistischer Parameter implementiert und die resultierenden linearen Modelle mit denen der bisher verwendeten Parameter verglichen. Zusätzlich wurde der Einfluss der Spotakkumulation und die Energieabhängigkeit der Modelle untersucht. Nachdem die Datenverarbeitung optimiert werden konnte, zeigte der Vergleich der Modelle eine deutlich bessere Vorhersage der neu entwickelten Modelle (R2 > 0;5) im Vergleich zu den bisher verwendeten Modellen (R2 < 0;1), wobei eine weitere Verbesserung durch die Akkumulation von Spots erreicht werden konnte (R2 > 0;9). Weiterhin zeigte die Parameterselektion eine deutlich bessere Vorhersagekraft der energiespezifischen (RMSE < 1;8 mm) gegenüber den energieunabhängigen Modellen (RMSE > 3 mm). Die gewonnenen Erkenntnisse leisten einen wesentlichen Beitrag zur klinischen Implementierung der PGT-Methode. / Prompt Gamma-Ray Timing (PGT) is a promising method for in vivo range verification in proton therapy. The distribution of prompt gamma radiation, in which the proton range is encoded, is measured in a time-resolved manner with uncollimated scintillation detectors. In this work, PGT spectra acquired during irradiation of a plastic phantom with air cavities of different thicknesses were analyzed. In addition to the optimization of the data processing, methods for parameter selection were implemented and the resulting linear models were compared with those of previously used parameters. In addition, the influence of a spot accumulation and the energy dependency of the models were examined. After the data preprocessing could be optimized, the newly developed models showed a strongly improved predictive power (R2 > 0;5) compared to the previously used models (R2 < 0;1) and a further improvement could be achieved by the accumulation of spots (R2 > 0;9). In addition the parameter selection showed better predictive power of the energy-specific models (RMSE < 1;8 mm) compared to the energy-independent models (RMSE > 3 mm). The knowledge gained can contribute to the clinical implementation of the PGT method.

Current research indicates that the inability to spontaneously communicate needs or wants may result in the acquisition of unconventional forms of requesting such as aggression and tantrums. This in turn limits the amount of access that students with autism have to neurotypical peers and social environments. The purpose of this study was to investigate the effect of using a stimulus control transfer procedure on the acquisition of spontaneous mands. Four school-aged children with autism, two boys and two girls, participated in the study. A multiple baseline design across participants was utilized to demonstrate a functional relation between the stimulus control transfer procedures and the rate of spontaneous mands. Measurement variables included the frequency of spontaneous versus multiply-controlled mands during discrete trial training on a variety of verbal operants. Effectiveness of the intervention was analyzed through visual analysis and the magnitude of effect was assessed through effect size. Visual analysis indicated that three of the four participants learned to spontaneously mand for items out of view and demonstrated generalization across targets, staff and environments. The effect size for three participants were large (d = 1.94; d = 2.2; and d = 1.4), whereas the outcome of intervention for one participant (d = 0.98) indicated moderate effect. The overall (d = 1.15) outcome demonstrated a large effect of the intervention on the rate of mands. Based on the results of this study, it is recommended that early and intensive behavior intervention programs for children with autism incorporate this type of procedure for socially significant outcomes.
