First-time parenting couples' stress associated with at-risk pregnancy and antenatal hospitalization

Polomeno, Viola 12 1900 (has links)
Thèse numérisée par la Direction des bibliothèques de l’Université de Montréal / The goals of this study were: (1) to determine the contribution of the stressors (atrisk pregnancy and antenatal hospitalization), the resources (conjugal adjustment and satisfaction from others) and the perception of the stressors (primary stress appraisal: threat, challenge, centrality; and secondary stress appraisal: control-self, control-others, incontroUable) to first-time parenting couples' global stress associated with at-risk pregnancy and antenatal hospitalization, and (2) to assess congruence between the partners' perceptions of stress in terms of similarities. Three types of similarities are considered, produced from combinations of self-perceptions (a person's direct perception) and metaperceptions (a person's perception of another person): actual similarity, perceived similarity and understanding. The non-probabilistic sample of 109 couples was recruited fi'om 12 perinatal units in the Montreal region. The couples completed four questionnah-es: The Personal and Pregnancy Information Guide, the Dyadic Adjustment Scale, the Support Behaviors Inventory, and the Stress Appraisal Measure. Using Boss' model (1988) The Contextual Model of Family Stress to study the first research goal, 52% of the variance regarding the women's global stress was explained by primary stress appraisal (threat, challenge, centrality), while 60% of the variance regarding the men's global stress was explained by the stressors (gestation, prenatal classes, education) and primary stress appraisal (threat, centrality). For the couples' models, 33% of their global stress at the level of actual similarity was explained by prunary stress appraisal (threat, centrality), while at the level of perceived similarity, 32% of the explained variance was due to primary stress appraisal (threat, centrality) and secondary stress appraisal (controlself, control-others). At the level of understanding, 32% of the explained variance is attributed to the resources (dyadic cohesion) and primary stress appraisal (threat, centrality). Further analyses were conducted on couples' perceptions since primary stress appraisal was found to be a significant predictor of thek global stress (second research goal). In order to attain this, five hypotheses were tested: HI: There is a significant difference in the perceived similarity of global stress appraisal between women and men (confirmed); H2: There is a significant difference in understanding of global stress appraisal between women and men (confirmed); H3: There is congruence between women's and men's perceived smiilarity and actual similarity for global stress appraisal (partially confirmed); H4: There is congruence between women's and men's understanding and actual smiilarity for global stress appraisal (partially confirmed); and, H5: There is congruence between women's and men's understanding and women's and men's perceived smiilarity for global stress appraisal (partially confirmed). Despite the couples' moderate stress appraisal, women perceive at-risk pregnancy and antenatal hospitaUzation as a threat, and their global perception of stress is significantly higher than that of the men. Men perceive the same stressors as a challenge and being in control of the situation. The couples are congruent in actual similarity except for the means of challenge and self-control. Regarding perceived similarity, there are no significant differences for the women whereas for the men, there are significant discrepancies for the means of threat and global stress. For women's understanding, there are significant discrepancies between the means of for threat and global stress, while for the men, there are no significant differences. Women are more stressed by at-risk pregnancy and antenatal hospitalization than the men, resulting in a greater lack of congruence between the different sunilarities. They are less available for the conjugal relationship, while the men are more understanding and more available to devote themselves to the relationship: the men's optimism appears to reduce the women's stress with an impact on the relationship. Regarding couples' stress, there is a gradual shift in perceiving the strcssors as threatening to perceiving them as important for their well-being. Also, control and the conjugal relationship become more unportant at the levels of perceived similarity and understanding respectively. In conclusion, women and men do not perceive the stressors in the same way, and that nurses and other health care professionals should consider both partners' perceptions as weU as that of the couple's in their global evaluation of stress during their interventions. Nurses' greater challenge is to help a couple to be 'a couple' in the hospital setting in order to help them protect their love and intimacy. / Les buts de cette étude étaient: (l) d'évaluer la contribution des stresseurs (la grossesse à risque et l'hospitalisation), des ressources (rajustement conjugal et la satisfaction du soutien des autres) et de la perception des stresseurs (évaluation primaire: menace, défi, centralité; évaluation secondaire: contrôle-soi, contrôle-autres, incontrôlable) sur le niveau de stress relié à la grossesse à risque et l'hospitalisation anténatale chez des couples sans enfant; et (2) d'évaluer la congruence entre les perceptions des partenaires en termes de similarités. Trois types de similarités sont analysés, lesquels proviennent de la combinaison des autoperceptions (la perception directe d'une personne) et des méta-perceptions (la perception qu'une personne a de l'autre): la similarité actuelle, la similarité perçue et la compréhension. L'échantillon nonprobabiliste comprend 109 couples recrutés dans 12 unités périnatales de la grande région de Montréal. Les couples ont rempli quatre questionnaires: le Guide d'information personnelle et périnatale, l'Échelle d'ajustement dyadique, l'Inventaire de comportements de soutien, et l'Échelle d'évaluation du stress. Afin d'atteindre le premier but de la recherche, Le modèle contextuel de stress familial de Boss (1988) a été utUisé: 52% de la variance du stress global chez les femmes est expliqué par l’évaluation primaire (menace, défi, centralité), tandis chez les hommes, 60% de la variance de leur stress global est expliqué par les stresseurs (gestation, cours prénataux, éducation) et l’évaluation primaire (menace, centralité). En ce qui concerne les modèles chez les couples, 33% de leur stress global au niveau de la similarité actuelle est expliqué par l’évaluation primaire, tandis qu'au niveau de la similarité perçue, 32% de la variance est expliqué par l’évaluation primaire (menace, centralité) et l’évaluation secondaire (contrôle-soi, contrôle-autres). Au niveau de la compréhension, 32% de la variance est expliqué par les ressources (cohésion dyadique) et l’évaluation primaire (menace, centralité). Les analyses sur la perception des stresseurs ont été approfondies puisque celle-ci expliquait le stress global stress chez les femmes, les hommes et les couples (deuxième but de la recherche). Donc, cinq hypothèses ont été testées: HI: II y a une différence significative entre le niveau de similarité perçue du stress global des femmes et celui des hommes (confirmée); H2: II y a une différence significative entre le niveau de compréhension du stress global des femmes et celui des hommes (confirmée); H3: Il y a congruence entre la similarité perçue chez les femmes et les hommes et la similarité actuelle du stress global (partiellement confirmée); H4: II y a congruence entre la compréhension chez les femmes et les hommes et la similarité actuelle du stress global (partiellement confirmée); et, H5: Il y a congruence entre la compréhension chez les femmes et les hommes et la similarité perçue chez les femmes et les hommes du stress global (partiellement confirmée). Malgré le niveau de stress moyen des couples, les femmes perçoivent la grossesse à risque élevé et l'hospitalisation anténatale comme une menace, et leur niveau de stress global est significativement plus élevé que chez les hommes. Les hommes perçoivent les mêmes stresseurs comme un défi et d'être en contrôle de la situation. Les couples sont congruents quant à la similarité actuelle sauf le défi et le contrôle-de-soi. A l'égard de la similarité perçue, il n'y a pas de différence significative chez les femmes, tandis que pour les hommes, il y a des différences significatives entre les moyennes de la menace et du stress global. Au niveau de la compréhension des femmes, il y a des différences significatives entre les moyennes de la menace et du stress global, tandis qu'il n'y a pas chez les hommes. Les femmes sont plus stressées que les hommes face aux stresseur de la grossesse à risque et de l'hospitalisation anténatale, ayant comme conséquence un plus grand manque de congruence entre les différents niveaux de similarités. Elles sont donc moins disponibles pour la relation conjugale. Tandis que les hommes semblent plus compréhensifs et plus disponibles pour se consacrer à la relation conjugale, leur optimisme semble diminuer le stress ressenti par les femmes. En ce qui concerne le stress global des couples, les résultats suggèrent qu'il y a une transformation graduelle de la perception du stresseur vers une perception basée sur le bien-être du couple. Aussi, le contrôle et la relation conjugale deviennent plus importants aux niveaux de la similarité perçue et de la compréhension respectivement. En conclusion, les femmes et les hommes ne perçoivent pas les stresseurs de la même façon. Les infirmières et les autres professionnels de la santé doivent tenir compte des perceptions de chaque partenaire ainsi que celles du couple dans l’évaluation globale du stress. Le plus grand défi des infirmières est d'aider le couple d'être couple en milieu hospitalier afin de protéger leur intimité.

Stora språkmodeller för bedömning av applikationsrecensioner : Implementering och undersökning av stora språkmodeller för att sammanfatta, extrahera och analysera nyckelinformation från användarrecensioner / Large Language Models for application review data : Implementation survey of Large Language Models (LLM) to summarize, extract, and analyze key information from user reviews

von Reybekiel, Algot, Wennström, Emil January 2024 (has links)
Manuell granskning av användarrecensioner för att extrahera relevant informationkan vara en tidskrävande process. Denna rapport har undersökt om stora språkmodeller kan användas för att sammanfatta, extrahera och analysera nyckelinformation från recensioner, samt hur en sådan applikation kan konstrueras.  Det visade sig att olika modeller presterade olika bra beroende på mätvärden ochviktning mellan recall och precision. Vidare visade det sig att fine-tuning av språkmodeller som Llama 3 förbättrade prestationen vid klassifikation av användbara recensioner och ledde, enligt vissa mätvärden, till högre prestation än större språkmodeller som Chat-Bison. För engelskt översatta recensioner hade Llama 3:8b:Instruct, Chat-Bison samt den fine-tunade versionen av Llama 3:8b ett F4-makro-score på 0.89, 0.90 och 0.91 respektive. Ytterligare ett resultat är att de större modellerna Chat-Bison, Text-Bison och Gemini, presterade bättre i fallet för generering av sammanfattande texter, än de mindre modeller som testades vid inmatning av flertalet recensioner åt gången.  Generellt sett presterade språkmodellerna också bättre om recensioner först översattes till engelska innan bearbetning, snarare än då recensionerna var skrivna i originalspråk där de majoriteten av recensionerna var skrivna på svenska. En annan lärdom från förbearbetning av recensioner är att antal anrop till dessa språkmodeller kan minimeras genom att filtrera utifrån ordlängd och betyg.  Utöver språkmodeller visade resultaten att användningen av vektordatabaser och embeddings kan ge en större överblick över användbara recensioner genom vektordatabasers inbyggda förmåga att hitta semantiska likheter och samla liknande recensioner i kluster. / Manually reviewing user reviews to extract relevant information can be a time consuming process. This report investigates if large language models can be used to summarize, extract, and analyze key information from reviews, and how such anapplication can be constructed.  It was discovered that different models exhibit varying degrees of performance depending on the metrics and the weighting between recall and precision. Furthermore, fine-tuning of language models such as Llama 3 was found to improve performance in classifying useful reviews and, according to some metrics, led to higher performance than larger language models like Chat-bison. Specifically, for English translated reviews, Llama 3:8b:Instruct, Chat-bison, and Llama 3:8b fine-tuned had an F4 macro score 0.89, 0.90, 0.91 respectively. A further finding is that the larger models, Chat-Bison, Text-Bison, and Gemini performed better than the smaller models that was tested, when inputting multiple reviews at a time in the case of summary text generation.  In general, language models performed better if reviews were first translated into English before processing rather than when reviews were written in the original language where most reviews were written in Swedish. Additionally, another insight from the pre-processing phase, is that the number of API-calls to these language models can be minimized by filtering based on word length and rating. In addition to findings related to language models, the results also demonstrated that the use of vector databases and embeddings can provide a greater overview of reviews by leveraging the databases’ built-in ability to identify semantic similarities and cluster similar reviews together.

Ambient Temperature Estimation : Exploring Machine Learning Models for Ambient TemperatureEstimation Using Mobile’s Internal Sensors

Omar, Alfakir January 2024 (has links)
Ambient temperature poses a significant challenge to the performance of mobile phones, impacting their internal thermal flow and increasing the likelihood of overheating, leading to a compromised user experience. The knowledge about the ambient temperature in mobile phones is crucial as it assists engineers in correlating external factors with internal factors that might affect the mobile's performance under various conditions. Notably, these devices lack dedicated sensors to measure ambient temperature independently, underscoring the need for innovative solutions to estimate it accurately.      In response to this challenge, our research investigates the feasibility of estimating ambient temperature using machine-learning algorithms based on data from internal thermal sensors in Sony mobile phones.  Through comprehensive data collection and analysis, custom datasets were constructed to simulate different use-case scenarios, including CPU workloads, camera operation, and GPU tasks. These scenarios introduced varying levels of thermal disturbance, providing a robust basis for evaluating model performance. Feature engineering played a pivotal role in ensuring that the models could effectively interpret the internal thermal dynamics and correlate them with the ambient temperature. The results demonstrate that while simpler models like Linear Regression offer computational efficiency, they fall short in scenarios with complex thermal patterns. In contrast, deep learning models, particularly those incorporating time series analysis, showed superior accuracy and robustness. The Attention-LSTM model, in particular, excelled in generalizing across diverse and novel thermal conditions, although its complexity poses challenges for on-device deployment. This research underscores the importance of selecting appropriate sensors and incorporating a wide range of training scenarios to enhance model performance. It also highlights the potential of advanced machine learning techniques in providing advance solutions for ambient temperature estimation, thereby contributing to more effective thermal management in mobile devices.
