<p>Fundamental changes have been happening in healthcare organizations and delivery in these decades, including more accessible physician information, the low-cost collection and sharing of clinical records, and decision support systems, among others. Emerging information systems and technologies play a signification role in these transformations. To extend the understanding and the implications of information systems on healthcare, my dissertation investigates the influence of information systems on enhancing healthcare operations. The findings reveal the practical value of digitalization in indicating healthcare providers' cognitive behaviors, responding to healthcare crises, and improving medical performance.</p> <p><br></p> <p>The first essay investigates the unrevealed value of a special type of user-generated content in healthcare operations. In today's social media world, individuals are willing to express themselves on various online platforms. This user-generated content posted online help readers get easy assess to individuals' features, including but not limited to personality traits. To study the impact of physicians' personality traits on medicine behaviours and performance, we take a view from the perspective of user generated content posted by their supplier side as well as using physician statements which have been made available in medical review websites. It has been found that a higher openness score leads to lower mortality rates, reduced lab test costs, shorter time usage in hospitals treated by physicians with greater openness scores. Furthermore, taking these personality traits into consideration in an optimization problem of ED scheduling, the estimation of counterfactual analysis shows an average of 11.4%, 18.4%, and 17.8% reduction in in-hospital mortality rates, lab test expenditures, and lengths of stay, respectively. In future operation of healthcare, physicians' personalities should be taken into account when healthcare resources are insufficient in times of healthcare pandemics like COVID-19, as our study indicates that health service providers personality is an actual influence on clinical quality.</p> <p><br></p> <p>In the second essay, we focus on the influences of the most severe healthcare pandemic in these decades, COVID-19, on digital goods consumption and examine whether digital goods consumption is resilient to an individual’s physical restriction induced by the pandemic. Leveraging the enforced quarantine policy during the COVID-19 pandemic as a quasi-experiment, we identify the influence of a specific factor, quarantine policy, on mobile app consumption in every Apple app store category in the short and long terms. In the perspective of better responding in the post-pandemic era, the quantitative findings provide managerial implications to the app industry as well as the stock market for accurately understanding the long-term impact of a significant intervention, quarantine, in the pandemic. Moreover, by using the conditional exogenous quarantine policy to instrument app users’ daily movement patterns, we are able to further investigate the digital resilience of physical mobility in different app categories and quantify the impact of an individual’s physical mobility on human behavior in app usage. For results, we find that the reduction in 10% of one’s physical mobility (measured in the radius of gyration) leads to a 2.68% increase in general app usage and a 5.44% rise in app usage time dispersion, suggesting practitioners should consider users’ physical mobility in future mobile app design, pricing, and marketing.</p> <p><br></p> <p>In the third essay, we investigate the role of an emerging AI-based clinical treatment method, robot-assisted surgery (RAS), in transforming the healthcare delivery. As an advanced technique to help diminish the human physical and intellectual limitations in surgeries, RAS is expected to but has not been empirically proven to improve clinical performance. In this work, we first investigate the effect of RAS on clinical outcomes, controlling physicians' self-selection behavior in choosing whether or not to use RAS treatment methods. In particular, we focus on the accessibility of RAS and explore how physician and patient heterogeneity affect the adoption of the RAS method, including learning RAS and using RAS. Investigating the decision-making process on RAS implementation in both the learning and using stages, we show the synergy of RAS implementation in alleviating healthcare racial disparity. Ultimately, the mechanism analysis will be conducted to reveal the underlying mechanism that induces the enhancement of surgical outcomes. For instance, the estimations tend to reveal that, more than surging clinical performance, RAS tends to increase standardization in time and steps when applying the treatment procedures. </p>

Överkonsumtion är idag ett stort problem och kött är en bidragande faktor till växthuseffekten. I Sverige lever vi idag som att vi har 4,2 jordklot vilket inte är hållbart i längden. Syftet med studien är att undersöka om företag genom nudgingtekniker kan påverka konsumenten att göra ett mer hållbart matval i digitala konsumtionsmiljöer. Studien har utgått från teorier från beteendeekonomi och konsumentbeteende där nudging ingår. En enkätundersökning har genomförts som riktade sig till respondenter i åldrarna 18-28 år där svarsfrekvensen blev 228 svar som senare utgjort grund för resultatet i studien. I resultatdelen har datan från den kvantitativa undersökningen presenterats i form av en deskriptiv analys med tre avsnitt, Paired Samples Proportions tester och Chi2-tester. Diskussion har därefter förts där resultatet har analyserats i relation till den teoretiska referensramen. Studien bekräftar tidigare forskning, däribland att flera nudingetoder kombinerade med varandra alstrar effekt. Hybridnudge och prisnudge identifieras som de mest effektiva metoderna för företag att tillämpa för att rikta in konsumenter mellan 18 och 28 år att välja det hållbara matalternativet vid digital konsumtion. Slutligen visar det deskriptiva resultatet att kvinnor påverkas av de undersökta nudgingmetoderna betydligt mer än män, vilket har visat samband genom Chi2-tester samt att åldersspannet 22 till 24 år är dem som influeras mest till att ändra sina konsumtionsmönster. / Overconsumption is today a major problem and meat is a contributing factor to the greenhouse effect. In Sweden, we live today as if we have 4.2 globes, which is not sustainable in the long run. The purpose of the study is to investigate whether companies, through nudging techniques, can influence the consumer to make a more sustainable food choice in digital consumption environments. The study is written in Swedish and has been based on theories from behavioral economics and consumer behavior where nudging is included. A questionnaire survey has been conducted which was aimed at respondents aged 18-28 where the response rate was 228 responses which later formed the basis for the results of the study. In the results section, the data from the quantitative survey has been presented in the form of a descriptive analysis with three sections, Paired Samples Proportions tests and Chi2 tests. A discussion has then taken place where the results have been analyzed in relation to the theoretical framework of reference. The study confirms previous research, including that several nudging methods combined with each other produce a greater effect. Hybrid nudge and price nudge is identified as the most effective method for companies to apply to target consumers between the ages of 18 to 28 to choose the sustainable food option in digital consumption. Finally, the descriptive results show that women are affected by the investigated nudging methods significantly more than men, which has shown a relationship through Chi2-tests and that the age group 22 to 24 years old are the ones most influenced to change their consumption patterns.

- ABSTRACT – Title: Winners of the Web ( Webbens vinnare) Number of pages: 35 (including enclosures) Author: Lydia Kellam Tutor: Else Nygren Course: Media and Communication Studies C Period: Fall Semester 2006 University: Division of Media and Communication, Department of Information Science Purpose: The aim of the research paper was to see Internet and the digital techniques impact on marketing communication and consuming behavior on the Web. By understanding the relationship between marketing communication and consumer behavior my intentions were to comprehend how consumer behavior on the web could be understand. The purpose of this paper is to understand how different marketing activities on the Internet are followed by consumption. Material/Method: By using focus group interviews I wanted to study how individuals act on the Internet. How different activities such as communication and participation on the web could lead to consumption on the Internet. As a method, focus group interviews capture the social interactions and participants affect each other. The social effect, in particularly, gained the results and the analysis of this paper. Main Result: Consumer on the Internet experience that commercial messages on the Web are overloaded, and use consumer powered sites an alternative. Consumer driven websites increases and so is the influence of the consumer,since users on the web reject the commercial messages, a strategy where the interaction between companies and consumer is supportive for both parties is demanded. There fore a more individual aim on the marketing communication on the Internet is required. For example commercial messages that are directed to a specific consumer, and that relate to the interactive possibilities on the Web.
