Contextual Affordances of Social Media, Clinical Prosess Changes and Health Service Outcomes

Zheng, Haoran 24 August 2018 (has links)
Never had consumers been empowered by information technologies such as social media-enabled portals that permit them to access and conduct all aspects of life and work activities through a mobile phone at any time from anywhere. WeChat, with over 963 million active monthly users, represents such a revolutionary platform. In healthcare, patients can use WeChat to make doctor appointments, access health and lab results, consult with doctors, and check on the queuing status and parking conditions in the health clinics and hospitals. Such social-media-enabled systems have transformed the relationships between consumers and businesses into a new paradigm in which the supply-side is driven by the demand-side. As a result, the new technology is fundamentally changing; not only the context in which business is conducted but also the business itself. The extant literature on technology acceptance, however, has mostly focused on technical functionalities and user characteristics without adequately considering the specific context in which the technology is used. Although these affordance concepts have advanced our knowledge about the interactions between technology and users, the specific contexts in which such interactions occur have been largely ignored. There is a critical literature gap that hinders our ability to understand and provide guidelines to help organizations deal with the complex challenges they face in managing social mediaenabled technologies in today’s changing environment. Our research attempts to bridge this critical literature gap by conceptualizing the concept of contextual affordance, and by examining its determinants and consequences in healthcare services. We use a combination of qualitative method and quantitative method. Research sites are in China across multiple healthcare facilities. The anticipated findings include validated dimensions of contextual affordance and relationships between contextual affordance and its determinants and impacts on clinical process changes and health service outcomes. Theoretically, this study extends the current understanding of affordance by considering contextual dimensions of affordance, and by examining the relationships between contextual affordance and its determinants and consequences. Practically, this study sheds new lights on how organizations should go beyond the out-of-context interactions between technologies and users by considering users’ perceived affordance of technology within the specific contexts of use.

Den strategiska beslutsprocessen och Business Analytics / The Strategic Decision Making Process and Business Analytics

Gudfinnsson, Kristens January 2013 (has links)
Organisationer samlar oerhört mycket information som kan användas som stöd vid strategiskt beslutfattande. Det finns många olika verktyg som kan användas för att analysera informationen och skapa det beslutunderlaget som krävs för ett informationsbaserad strategiskt beslut. Verktygen förutsätter en rationell beslutsprocess där olika alternativ vägs och analyseras med resultatet att bästa möjliga beslut fattas. Business Analytics (BA) är ett paraply begrepp som innehåller olika verktyg och processer för att analysera och bearbeta information som bygger på den rationella beslutsprocessen. Företag kan delas in i två olika kategorier: de som fokuserar/säljer sina produkter till slutkonsumenter (B2C) och de som fokuserar/säljer sina produkter till företag (B2B). Litteraturen kring hur BA används som beslutstödssystem fokuserar på B2C organisationer som Amazon.com, Netflix eller Google, medan det finns väldigt lite skrivit kring hur B2B organisationer utnyttjar BA. B2B organisationer kännetecknas bland annat av att de har mycket färre kunder och producerar varor gärna ihop med sina kunder, till skillnad till B2C organisationer som kan ha enorma kundstockar. Det finns därför ett behov för att öka förståelsen för hur B2B organisationer utnyttjar BA som stöd i den strategiska beslutsprocessen. I detta arbete har ett B2B företag analyseras för att få en bild av hur den strategiska beslutsprocessen ser ut och hur BA används som ett verktyg vid beslutsfattande. I praktiken visar sig beslutsprocessen inte vara helt rationell utan mer som en blandning av otydliga och diffusa idéer och att beslutsunderlag mognar fram och utvecklas till en mer rationell process där BA kan användas för olika beräkningar och för att skapa beslutsunderlag. Strategiska beslutsprocessen initieras genom muntlig kommunikation ifrån samarbetspartners, kunder eller genom exempelvis möten och mässor. Det är inte förrän sent i processen som BA utnyttjas för att analysera information och då helst i form av lönsamhetskalkyler. En viktig faktor för att BA inte används tidigare i den strategiska beslutsprocessen är att organisationen normalt inte har tillgång till den information som ska analyseras förrän i ett senare skede i processen vilket gör att man inte kan ställa och utveckla frågor och idéer som kommer fram inom organisationen.

Welfare Losses from First-Come-First-Serve Course Enrollment: Outcome Estimation and Non-Market Maximization

Fontenot, Rory 01 January 2019 (has links)
College course enrollment operates as a market under supply cap. Because of the limited number of seats available for any given course some students who have a higher demand for a course are unable to enroll. The current registration system at the Claremont Colleges functions as a random draw system with added time costs. The lack of price signalling in the markets leads to a loss in overall welfare of the student body. By running data through simulated demand curves I am able to determine, on average, how much welfare is being lost by a random draw system. The percent of maximum welfare achieved compared to maximum possible ranges from forty-nine to eighty percent and largely depends on the proportion of enrolled students to the sum of enrolled + enroll requests as well as the demand function type. With price signalling, the student body would be able to reach the maximum achievable welfare.

Exploring Business Intelligence Commitment and Maturity in Small and Medium Sized Enterprises

Gudfinnsson, Kristens January 2011 (has links)
Implementing Business Intelligence solutions has fundamentally changed how many large organizations conduct their business. This is well understood in the scholarly literature but the adoption of BI within small or medium sized enterprises has, on the other hand, received little attention. Given the importance of small and medium sized enterprises (SMEs) in the economy, the scarcity of research in this area can be viewed as a problem. Thus, the aim of this work is to explore the BI-commitment in smaller-sized organizations and investigate how far they have proceeded in putting business analytics in action. In order to shed light on BI-implementation in the context of smaller organizations, in-depth interviews were conducted with representatives of four organizations within the Skaraborg district of Sweden. The initial objective of the research project was to explore several focal areas in order to establish the current state-of-practice. This provided the groundwork for further investigation on how SMEs approach BI. Further work involved the use of two theoretical frameworks to analyze organizational commitment and analytical maturity within the focal areas. The main findings in this work are that the organizational commitment to implement BI infrastructure is high among participating companies, but the use of analytics is nevertheless limited to few specific areas. The high ambition of managers to implement BI infrastructure can be the key to further develop the use of business analytics.  This work adds valuable insights for various stakeholders within the community and to others that want to have an idea of the current status of BI within SMEs in Sweden.

Taking Advantage of Business Intelligence in Complex-Systems Environment

Gudfinnsson, Kristens January 2012 (has links)
Business intelligence has fundamentally changed how many companies conduct their business. The focus of academic literature has however been on volume-operation companies that provide services to millions of customers. Complex-systems companies have fewer customers and pursue customer needs by providing more customized products and services. The knowledge in the research society is limited to volume-operation companies and there a need for more case studies regarding how companies actually use their information systems, specifically complex-systems companies. This work looks at a case of a complex-systems company with the overall aim to see how complex-systems companies may take advantage of business intelligence. A framework was used to measure BI maturity; expressed future needs were compared to future trends in BI literature and BI usage in specific areas was analyzed with the help of a framework from BI literature. The results indicate that the company is somewhere between Aspirational and Experienced with respect to BI maturity. BI is used for reporting a variety of key performance indicators and the main analysis tool for various calculations is Excel. The expressed future needs are mainly strategy-driven and technology-driven and often involve better and faster access to information. The difference in the business models of volume-operations companies and complex-systems companies could influence the BI maturity and help to explain the maturity difference between these two types of companies. Furthermore, the results indicate that there is a difference between the roles of BI tools in complex-systems companies compared to volume-operations.

New Trends in Business Intelligence : A case study on the impact of organizational demands of information and new technologies on BI

Naghdipour, Navid Naghdipour January 2014 (has links)
When the data warehouse concept was first introduced by IBM as a part of their new information system in 1988, the first step in the field of modern decision support systems or business intelligence was taken. Since then, academics, practitioners and solution developers have put a considerable effort in introducing new trends of these systems. Each new trend has roots in what enterprises demand from these systems. The advances in Web technologies and social media, has led to introduction of new trends such as Cloud BI and Big Data which are both cost-effective and also have the potential to take advantage of semi-structured and unstructured data within organizations. This paper deals with these new trends and the influences of organizational demands and new technologies and tools on them. A deep literature review deals with four major BI trends in detail. (Data warehouse, Business Performance Management (BPM), Cloud BI and Big Data). Two case studies from local Business intelligence developers are carried out in order to explore the influences mentioned above. As the result of this study, a model is proposed that addresses the elements that affect the BI trends, both in organizational and technological perspectives. It is observed that despite the fact that lots of new trends have been introduced in the past years (e.g. Cloud BI and Big Data), it does not necessarily mean that older trends are becoming obsolete. Data warehouses and BPM systems are still being used vastly in the industry. However, the later trends can be offered to clients that have the demand for them. The results imply that Cloud BI is mainly suitable for companies with low initial budgets and Big Data can be adopted by organizations that want to exploit their social data sources. The mere fact that both implied trends are built upon their preceding ones, has transformed data warehouses and BPM approach the ground work for any new trends to come.
