The FORA Framework - A Fuzzy Grassroots Ontology for Online Reputation Management

Online reputation management deals with monitoring and influencing the online record of a person, an organization or a product. The Social Web offers increasingly simple ways to publish and disseminate personal or opinionated information, which can rapidly have a disastrous influence on the online reputation of some of the entities. The author focuses on the Social Web and possibilities of its integration with the Semantic Web as resource for a semi-automated tracking of online reputations using imprecise natural language terms. The inherent structure of natural language supports humans not only in communication but also in the perception of the world. Thereby fuzziness is a promising tool for transforming those human perceptions into computer artifacts. Through fuzzy grassroots ontologies, the Social Semantic Web becomes more naturally and thus can streamline online reputation management. For readers interested in the cross-over field of computer science, information systems, and social sciences, this book is an ideal source for becoming acquainted with the evolving field of fuzzy online reputation management in the Social Semantic Web area. ​

The FORA Framework - A Fuzzy Grassroots Ontology for Online Reputation Management

Online reputation management deals with monitoring and influencing the online record of a person, an organization or a product. The Social Web offers increasingly simple ways to publish and disseminate personal or opinionated information, which can rapidly have a disastrous influence on the online reputation of some of the entities. This dissertation can be split into three parts: In the first part, possible fuzzy clustering applications for the Social Semantic Web are investigated. The second part explores promising Social Semantic Web elements for organizational applications,while in the third part the former two parts are brought together and a fuzzy online reputation analysis framework is introduced and evaluated. Theentire PhD thesis is based on literature reviews as well as on argumentative-deductive analyses.The possible applications of Social Semantic Web elements within organizations have been researched using a scenario and an additional case study together with two ancillary case studies—based on qualitative interviews. For the conception and implementation of the online reputation analysis application, a conceptual framework was developed. Employing test installations and prototyping, the essential parts of the framework have been implemented.By following a design sciences research approach, this PhD has created two artifacts: a frameworkand a prototype as proof of concept. Bothartifactshinge on twocoreelements: a (cluster analysis-based) translation of tags used in the Social Web to a computer-understandable fuzzy grassroots ontology for the Semantic Web, and a (Topic Maps-based) knowledge representation system, which facilitates a natural interaction with the fuzzy grassroots ontology. This is beneficial to the identification of unknown but essential Web data that could not be realized through conventional online reputation analysis. Theinherent structure of natural language supports humans not only in communication but also in the perception of the world. Fuzziness is a promising tool for transforming those human perceptions intocomputer artifacts. Through fuzzy grassroots ontologies, the Social Semantic Web becomes more naturally and thus can streamline online reputation management.

Endstation Notfallstation: Perzeption und Rezeption des Begriffs «palliativer Patient» sowie Ansätze zur Verbesserung der interdisziplinären Zusammenarbeit – ein Survey unter notfallmedizinischem Personal auf einer Schweizer Notfallstation

Hintergrund: Wegen sich verändernder Strukturen im Spitalbereich sowie im Bereich der Hausarztabdeckung als auch infolge zunehmenden Drucks auf das Gesundheitssystem kommen mehr Patienten auf die Notfallstationen, die aufgrund ihrer Grunderkrankung und des fortgeschrittenen Krankheitsstadiums von einem palliativen Behandlungskonzept profitieren. Eine wesentliche Herausforderung ist hierbei bereits die Definition von «Palliative Care» (PC), sowie die Klärung, was genau die palliative Versorgung beinhaltet. Häufig vermischt wird der Terminus «Palliative Care» mit «End of life care». Die vorliegende Studie ist eine Standortbestimmung im Universitären Notfallzentrum des Inselspitals Bern (UNZ), das jährlich rund 32 400 Patienten versorgt. Ziel ist es, mehr über den Wissensstand und die persönliche Einstellung der Mitarbeiter zu palliativen Fragestellungen und speziell zum Begriff «Palliative Care» zu erhalten. Methodik: Die Mitarbeiter des Universitären Notfallzentrums des Inselspitals Bern (UNZ) wurden mittels einer Online-Umfrage durch eine spitalexterne Fachinstitution interviewt. Diese Befragung basiert auf einem Instrument [1], das in einer vergleichbaren Studie auf einer Notfallstation in den USA entwickelt und validiert wurde. Resultate: Von 154 Mitarbeitenden (Pflege und Ärzte) füllten 60 Mitarbeitende die Befragung vollständig aus, entsprechend einer Antwortrate von 39%. Die Definition von Palliative Care (von n=60) war sehr heterogen und konnte in sechs Themenbereiche eingeteilt werden. Bei den Fragen nach spezifischen Leistungsangeboten äusserten die Mitarbeitenden den Wunsch nach einem erleichterten Zugang zu bestehenden Patientendaten, nach einem 24-Stunden-Palliative-Care-Konsiliardienst und nach mehr Besprechungszeit für Fragestellungen der PC im klinischen Alltag. Schlussfolgerungen: Die heterogene Begriffsdefinition von «Palliative Care» bestätigt sich. Es besteht kein klares Vorgehen, und zudem lässt sich ein Zeitmangel für ausführliche Patientengespräche in palliativen Situationen im UNZ feststellen. Der Patientenwunsch oder Patientenverfügungen mit DNR/DNI-Prozedere stehen nicht im Widerspruch zu den persönlichen Wertvorstellungen der meisten Mitarbeitenden. Die 24-Stunden-Verfügbarkeit eines spezialisierten PC-Teams, das Erarbeiten von Guidelines und vermehrtes Training für PC würde von den UNZ-Mitarbeitenden begrüsst.

Concordance between medical records and personal interview in ascertaining breast cancer and diabetes status: Analysis of the south Texas women's health project

Accurate ascertainment of risk factors and disease status is vital in public health research for proper classification of research subjects. The two most common ways of obtaining this data is by self-report and review of medical records (MRs). South Texas Women’s Health Project was a case-control study looking at interrelationships between hormones, diet, and body size and breast cancer among Hispanic women 30-79 years of age. History of breast cancer, diabetes mellitus (DM) and use of DM medications was ascertained from a personal interview. At the time of interview, the subject identified her major health care providers and signed the medical records release form, which was sent to the designated providers. The MRs were reviewed to confirm information obtained from the interview.^ Aim of this study was to determine the sensitivity and specificity between MRs and personal interview in diagnosis of breast cancer, DM and DM treatment. We also wanted to assess how successful our low-cost approach was in obtaining pertinent MRs and what factors influenced the quality of MR or interview data. Study sample was 721 women with both self-report and MR data available by June 2007. Overall response rate for MR requests was 74.5%. MRs were 80.9% sensitive and 100% specific in confirming breast cancer status. Prevalence of DM was 22.7% from the interviews and 16% from MRs. MRs did not provide definite information about DM status of 53.6% subjects. Sensitivity and specificity of MRs for DM status was 88.9% and 90.4% respectively. Disagreement on DM status from the two sources was seen in 15.9% subjects. This discordance was more common among older subjects, those who were married and were predominantly Spanish speaking. Income and level of education did not have a statistically significantly association with this disagreement.^ Both self-report and MRs underestimate the prevalence of DM. Relying solely on MRs leads to greater misclassification than relying on self-report data. MRs have good to excellent specificity and thus serve as a good tool to confirm information obtained from self-report. Self-report and MRs should be used in a complementary manner for accurate assessment of DM and breast cancer status.^

FAMILY MEDICINE RESIDENT SURVEY ON HEALTH PROMOTION (PERSONAL EXPECTATIONS, BEHAVIORS, PERCEIVED SELF-EFFICACY, COGNITIVE ASSESSMENT, OUTCOME EXPECTANCY)

This study was designed to test the theoretical predictors of personal efficacy expectations among family medicine resident physicians for helping their patients change thirteen high risk health behaviors. A survey questionnaire was sent to 781 family medicine residents in the six state south central region. The response rate was 60 percent. The hypothesized relationship between lower levels of difficulty and higher personal efficacy expectations was supported by the data. Effort was a significant predictor of perceived self efficacy for health behaviors considered less difficult to change. Situational support did not prove to be a significant predictor for many of the health behaviors. Rate and pattern of success were consistent and significant predictors of perceived self efficacy for helping patients change all thirteen of the health behaviors. Modeling of effective methods by faculty was a significant predictor of efficacy expectations for several but not all of the behaviors. Personal modeling was a significant predictor of perceived efficacy for helping patients change behaviors related to alcohol misuse and exercise. The respondents personally modeled positive health behaviors more consistently than their older colleagues or the general population.^ The results of this study lend substantially to the usefulness of the cognitive-behavioral theory of perceived self efficacy and provide a mechanism for assessing the predictors of personal efficacy expectations of family medicine resident physicians. The findings are expected to have direct implications for faculty to institute systematic programs of interventions designed to increase residents' perceptions of efficacy in facilitating more positive health behaviors among their patients. ^

Use of intranet and other interventions to increase influenza vaccination among health care workers

Influenza (the flu) is a serious respiratory illness that can cause severe complications, often leading to hospitalization and even death. Influenza epidemics occur in most countries every year, usually during the winter months. Despite recommendations from the Centers for Disease Control and Prevention (CDC) and efforts by health care institutions across the United States, influenza vaccination rates among health care workers in the United States remain low. How to increase the number of vaccinated health care workers is an important public health question and is examined in two journal articles included here. ^ The first journal article evaluates the effectiveness of an Intranet intervention in increasing the proportion of health care workers (HCWs) who received influenza vaccination. Hospital employees were required go to the hospital's Intranet and select "vaccine received," "contraindicated," or "declined" from the online questionnaire. Declining employees automatically received an online pop-up window with education about vaccination; managers were provided feedback on employees' participation rates via e-mail messages. Employees were reminded of the Intranet requirement in articles in the employee newsletter and on the hospital's Intranet. Reminders about the Intranet questionnaire were provided through managers and newsletters to the HCWs. Fewer than half the employees (43.7%) completed the online questionnaire. Yet the hospital witnessed a statistically significant increase in the percentage of employees who received the flu vaccine at the hospital – 48.5% in the 2008-09 season as compared to 36.5%, 38.5% and 29.8% in the previous three years (P < 0.05). ^ The second article assesses current interventions employed by hospitals, health systems and nursing homes to determine which policies have been the most effective in boosting vaccination rates among American health care workers. A systematic review of research published between January 1994 and March 2010 suggests that education is necessary but not usually sufficient to increase vaccine uptake. Education about the flu and flu vaccines is most effective when complemented with easy access and making the vaccine free, although this combination may not be sufficient to achieve the desired vaccination levels among HCWs. The findings point toward adding incentives for HCWs to get vaccinated and requiring them to record their vaccination status on a declination/consent form – either written or electronic. ^ Based on these findings, American health care organizations, such as hospitals, nursing homes, and long-term care facilities, should consider using online declination forms as a method for increasing influenza vaccination rates among their employees. These online forms should be used in conjunction with other policies, including free vaccine, mobile distribution and incentives. ^ To further spur health care organizations to adopt policies and practices that will raise influenza vaccination rates among employees, The Joint Commission – an independent, not-for- profit organization that accredits and certifies more than 17,000 health care organizations and programs in the United States – should consider altering its standards. Currently, The Joint Commission does not require signed declination forms from employees who eschew vaccination; it only echoes the CDC's recommendations: "Health care facilities should require personnel who refuse vaccination to complete a declination form." Because participation in Joint Commission accreditation is required for Medicare reimbursement, action taken by the Joint Commission to require interventions such as mandatory declination/consent forms might result in immediate action by health care organizations to follow these new standards and lead to higher vaccination rates among HCWs.^ 1“Frequently Asked Questions for H1N1 and Seasonal Influenza.” The Joint Commission - Infection Control: http://www.jointcommission.org/PatientSafety/InfectionControl/h1n1_faq.htm. ^

Exploring the economic value of personal information from firms' financial statements

Currently personal data gathering in online markets is done on a far larger scale and much cheaper and faster than ever before. Within this scenario, a number of highly relevant companies for whom personal data is the key factor of production have emerged. However, up to now, the corresponding economic analysis has been restricted primarily to a qualitative perspective linked to privacy issues. Precisely, this paper seeks to shed light on the quantitative perspective, approximating the value of personal information for those companies that base their business model on this new type of asset. In the absence of any systematic research or methodology on the subject, an ad hoc procedure is developed in this paper. It starts with the examination of the accounts of a number of key players in online markets. This inspection first aims to determine whether the value of personal information databases is somehow reflected in the firms’ books, and second to define performance measures able to capture this value. After discussing the strengths and weaknesses of possible approaches, the method that performs best under several criteria (revenue per data record) is selected. From here, an estimation of the net present value of personal data is derived, as well as a slight digression into regional differences in the economic value of personal information.

Information needs of rural health professionals: a review of the literature

This review analyzes the existing research on the information needs of rural health professionals and relates it to the broader information-needs literature to establish whether the information needs of rural health professionals differ from those of other health professionals. The analysis of these studies indicates that rural health practitioners appear to have the same basic needs for patient-care information as their urban counterparts, and that both groups rely on colleagues and personal libraries as their main sources of information. Rural practitioners, however, tend to make less use of journals and online databases and ask fewer clinical questions; a difference that correlates with geographic and demographic factors. Rural practitioners experience pronounced barriers to information access including lack of time, isolation, inadequate library access, lack of equipment, lack of skills, costs, and inadequate Internet infrastructure. Outreach efforts to this group of underserved health professionals must be sustained to achieve equity in information access and to change information-seeking behaviors.
