Information, and information and communication technologies (ICTs) are critical for most developed post-industrial societies. It follows, therefore, that the better the quality of the information exchanged, the more likely such societies and their members may prosper. But what is information quality (IQ) exactly? This paper discusses current definitions, problems and approaches to IQ and the question of how we should, and could, evaluate IQ in the future.

In this opening chapter, we review the literature on information quality. Our major aim is to introduce the issues, and trace some of the history of the debates, with a view to situating the chapters in this volume – whose authors come from different disciplines – to help make them accessible to readers with different backgrounds and expertise. We begin in this section by tracing some influential analyses of IQ in computer science. This is a useful basis for (...) examining some examples of developing work on IQ in section two. We look at some cases for applying IQ in section three, and conclude with some discussion points in section four. (shrink)

This work fulfills the need for a conceptual and technical framework to improve understanding of Information Quality (IQ) and Information Quality standards. The meaning and practical implementation of IQ are addressed, as it is relevant to any field where there is a need to handle data and issues such as accessibility, accuracy, completeness, currency, integrity, reliability, timeliness, usability, the role of metrics and so forth are all a part of Information Quality. -/- In order (...) to support the cross-fertilization of theory and practice, the latest research is presented in this book. The perspectives of experts from beyond the origins of IQ in computer science are included: library and information science practitioners and academics, philosophers of information, of engineering and technology, and of science are all contributors to this volume. -/- The chapters in this volume are based on the work of a collaborative research project involving the Arts and Humanities Research Council and Google and led by Professor Luciano Floridi, University of Oxford. -/- This work will be of interest to anyone handling data, including those from commercial, public, governmental and academic organizations. The expert editors’ contributions introduce issues of interest to scientists, database curators and philosophers, even though the issues may be disguised in the language and examples common to a different discipline.

The fact that Internet companies may record our personal data and track our online behavior for commercial or political purpose has emphasized aspects related to online privacy. This has also led to the development of search engines that promise no tracking and privacy. Search engines also have a major role in spreading low-quality health information such as that of anti-vaccine websites. This study investigates the relationship between search engines’ approach to privacy and the scientific quality of the (...) information they return. We analyzed the first 30 webpages returned searching “vaccines autism” in English, Spanish, Italian, and French. The results show that not only “alternative” search engines but also other commercial engines often return more anti-vaccine pages (10–53%) than Google (0%). Some localized versions of Google, however, returned more anti-vaccine webpages (up to 10%) than Google. Health information returned by search engines has an impact on public health and, specifically, in the acceptance of vaccines. The issue of information quality when seeking information for making health-related decisions also impact the ethical aspect represented by the right to an informed consent. Our study suggests that designing a search engine that is privacy savvy and avoids issues with filter bubbles that can result from user-tracking is necessary but insufficient; instead, mechanisms should be developed to test search engines from the perspective of information quality (particularly for health-related webpages) before they can be deemed trustworthy providers of public health information.

Social media platforms have been rapidly increasing the number of informational labels they are appending to user-generated content in order to indicate the disputed nature of messages or to provide context. The rise of this practice constitutes an important new chapter in social media governance, as companies are often choosing this new “middle way” between a laissez-faire approach and more drastic remedies such as removing or downranking content. Yet information labeling as a practice has, thus far, been mostly tactical, (...) reactive, and without strategic underpinnings. In this paper, we argue against defining success as merely the curbing of misinformation spread. The key to thinking about labeling strategically is to consider it from an epistemic perspective and to take as a starting point the “social” dimension of online social networks. The strategy we articulate emphasizes how the moderation system needs to improve the epistemic position and relationships of platform users — i.e., their ability to make good judgements about the sources and quality of the information with which they interact on the platform — while also appropriately respecting sources, seekers, and subjects of information. A systematic and normatively grounded approach can improve content moderation efforts by providing clearer accounts of what the goals are, how success should be defined and measured, and where ethical considerations should be taken into consideration. We consider implications for the policies of social media companies, propose new potential metrics for success, and review research and innovation agendas in this regard. (shrink)

This paper is divided into two parts. In the first, I shall briefly analyse the phenomenon of “big data”, and argue that the real epistemological challenge posed by the zettabyte era is small patterns. The valuable undercurrents in the ocean of data that we are accumulating are invisible to the computationally-naked eye, so more and better technology will help. However, because the problem with big data is small patterns, ultimately, the game will be won by those who “know how to (...) ask and answer questions” (Plato, Cratylus, 390c). This introduces the second part, concerning information quality (IQ): which data may be useful and relevant, and so worth collecting, curating, and querying, in order to exploit their valuable (small) patterns? I shall argue that the standard way of seeing IQ in terms of fit-for-purpose is correct but needs to be complemented by a methodology of abstraction, which allows IQ to be indexed to different purposes. This fundamental step can be taken by adopting a bi-categorical approach. This means distinguishing between purpose/s for which some information is produced (P-purpose) and purpose/s for which the same information is consumed (C-purpose). Such a bi-categorical approach in turn allows one to analyse a variety of so-called IQ dimensions, such as accuracy, completeness, consistency, and timeliness. I shall show that the bi-categorical approach lends itself to simple visualisations in terms of radar charts. (shrink)

Perceived quality of experience for speech listening is influenced by cognitive processing and can affect a listener's comprehension, engagement and responsiveness. Quality of Experience is a paradigm used within the media technology community to assess media quality by linking quantifiable media parameters to perceived quality. The established QoE framework provides a general definition of QoE, categories of possible quality influencing factors, and an identified QoE formation pathway. These assist researchers to implement experiments and to evaluate (...) perceived quality for any applications. The QoE formation pathways in the current framework do not attempt to capture cognitive effort effects and the standard experimental assessments of QoE minimize the influence from cognitive processes. The impact of cognitive processes and how they can be captured within the QoE framework have not been systematically studied by the QoE research community. This article reviews research from the fields of audiology and cognitive science regarding how cognitive processes influence the quality of listening experience. The cognitive listening mechanism theories are compared with the QoE formation mechanism in terms of the quality contributing factors, experience formation pathways, and measures for experience. The review prompts a proposal to integrate mechanisms from audiology and cognitive science into the existing QoE framework in order to properly account for cognitive load in speech listening. The article concludes with a discussion regarding how an extended framework could facilitate measurement of QoE in broader and more realistic application scenarios where cognitive effort is a material consideration.

TikTok has one of the most advanced algorithm systems and is the most addictive as compared to other social media platforms. While research on social media addiction is abundant, we know much less about how the TikTok information system environment affects users’ internal states of enjoyment, concentration, and time distortion, which in turn influences their addiction behavior. To fill this gap, this study collects responses from 659 adolescents in China aged between 10 and 19 years old, and the data (...) is then analyzed using Partial Least Square. We find that the system quality has a stronger influence than information quality in determining adolescents’ experience with TikTok and that the flow experience has significant direct and indirect effects on TikTok addiction behavior. Notably, this study finds that TikTok addiction is determined by users’ mental concentration on the medium and its content. Several theoretical insights from the stimulus–organism–response model and the flow theory are used to explain the findings. (shrink)

The COVID-19 pandemic triggered the first global “Infodemic” in the era of social media. Understanding how governments deal with the negative impacts of the infodemic has become a priority. This paper uses the theoretical framework of the Elaboration Likelihood Model to explore mechanisms for alleviating panic associated with the infodemic. It considers, in particular, the quality of information circulated on Government Social Media as the central route and local government trust as the peripheral route. An empirical study was (...) conducted using data from a focus group interview and a questionnaire survey collected within the first three weeks following the citywide lockdown of Wuhan, China. The results show that as: Quality of GSM information does not significantly reduce public panic, but local government trust significantly increases people’s pandemic prevention knowledge; Pandemic prevention knowledge is a critical mediator between information quality of GSM and public panic, as well as local government trust and public panic; and Information quality of GSM significantly increases people’s trust in local governments. This paper contributes to the literature on infodemic and government social media and provides implications for practice. (shrink)

Environmental information disclosure (EID) is an important part of environmental management practices, and it has become a reference for stakeholders to evaluate firms. To obtain support from stakeholders, such as analysts, firms can disclose information that indicates how good they perform in environmental protection, which we referred to as EID quality, and/or that covers multiple aspects of environmental protection, which we referred to as EID breadth. Given the importance of EID practices, this study examines whether and how (...) these two dimensions of EID affect corporate financial performance (CFP). Analyzing a sample of publicly listed manufacturing firms from 2009 to 2019 in China, we find that EID breadth has a positive relationship with CFP, while EID quality has a negative impact on CFP after controlling for EID breadth. In addition, we find that the positive impact of EID breadth on CFP is achieved by enhancing analyst coverage, while the effect of EID quality on CFP is achieved by analyst recommendation. Our work contributes to the literature on EID by uncovering different mechanisms about how EID quality and EID breadth affect CFP and offers important implications regarding the management and governance of EID practices.

Standard versions of the requirement of informed consent state that patients who are offered to enter a clinical trial of a medical procedure should be informed about risks and possible benefits of this procedure (compared to available alternatives) in order to facilitate a rational decision whether or not to participate. However, in many real cases where new medical procedures are to be clinically tested for the first time the information available for such communication to prospective patients is very scarce, (...) vague and/or uncertain. This phenomenon is illustrated by the clinical introduction of new procedures in reproductive medicine, such as preimplantation genetic diagnosis (PGD). Regarding such procedures, it has ben argued that, in such cases, the quality of the available information may be too low for the obtaining of informed consent to be possible, even if it is successfully communicated. Others, instead, holds that informed consent may always be obtained regardless of the quality of the available information. Unfortunately, the standard litterature on informed consent give no clue as to which of these interpretations is correct. This issue is explored by connecting the concept of informed consent to ethical ideas of respect for autonomy and ideas of rational decision making. It is argued, first, that low quality of available information regarding the risks and possible benefits of a medical procedure may indeed make the obtaining of informed consent from patients to undergo this procedure impossible even in theory. However, it is also argued that whether or not this is the case must be relativized to the actual needs and deires of individual patients. Thus, regarding one and the same procedure, informed consent may be impossible to obtain from some patients due to the low quality of the available information regarding this procedure, but still be possible to obtain from other patients.

BackgroundInformed consent is an ethical and legal requirement for research involving human participants. However, few studies have evaluated the process, particularly in Africa.Participants in a case control study designed to identify correlates of immune protection against tuberculosis (TB) in South Africa. This study was in turn nested in a large TB vaccine efficacy trial.The aim of the study was to evaluate the quality of consent in the case control study, and to identify factors that may influence the quality (...) of consent.Cross-sectional study conducted over a 4 month period.MethodsConsent was obtained from parents of trial participants. These parents were asked to complete a questionnaire that contained questions about the key elements of informed consent (voluntary participation, confidentiality, the main risks and benefits, etc.). The recall (success in selecting the correct answers) and understanding (correctness of interpretation of statements presented) were measured.ResultsThe majority of the 192 subjects interviewed obtained scores greater than 75% for both the recall and understanding sections. The median score for recall was 66%; interquartile range (IQR) = 55%–77% and for understanding 75% (IQR = 50%–87%). Most (79%) were aware of the risks and 64% knew that they participated voluntarily. Participants who had completed Grade 7 at school and higher were more likely (OR = 4.94; 95% CI = 1.57 – 15.55) to obtain scores greater than 75% for recall than those who did not. Participants who were consented by professional nurses who had worked for more than two years in research were also more likely (OR = 2.62; 95% CI = 1.35–5.07) to obtain such scores for recall than those who were not.ConclusionNotwithstanding the constraints in a developing country, in a population with low levels of literacy and education, the quality of informed consent found in this study could be considered as building blocks for establishing acceptable standards for public health research. Education level of respondents and experience of research staff taking the consent were associated with good quality informed consent. (shrink)

Our perceptual systems make information about the world available to our cognitive faculties. We come to think about the colors and shapes of objects because we are built somehow to register the instantiation of these properties around us. Just how we register the presence of properties and come to think about them is one of the central problems with understanding perceptual cognition. Another problem in the philosophy of perception concerns the nature of the properties whose presence we register. Among (...) the perceptible properties are colors and shapes, for example, and there is a long philosophical tradition of drawing and refusing to draw metaphysical distinctions between them. This paper makes a claim about the information-theoretic approach to perceptual cognition in order to argue for a fundamentally epistemological distinction between colors and shapes. What makes shapes and colors seem so different to us is how we carry information about their presence around us. In particular, we can come to know more about the shapes on the basis of perceiving them than we can come to know about the colors. One interesting feature of how this distinction is drawn is that it partially vindicates Locke’s claim that our ideas of primary qualities like shapes resemble them in ways our ideas of colors do not.

Patients have the right to refuse their treatment; however, this refusal should be informed. We evaluated the quality of the informed refusal process in Iranian hospitals from patients' viewpoints. To this end, we developed a questionnaire that covered four key aspects of the informed refusal process including; information disclosure, voluntariness, comprehension, and provider-patient relationship. A total of 284 patients who refused their treatment from 12 teaching hospitals in the Isfahan Province, Iran, were recruited and surveyed to produce a (...) convenience sample. Patients' perceptions about the informed refusal process were scored and the mean scores of the four components were calculated. The findings showed that the practice of information disclosure was perceived to be moderate, however, comprehension, voluntariness and provider–patient relationship were perceived to be relatively good. We found that patients, who refused their care before any treatment had commenced, reported a lower quality of information disclosure and voluntariness. Patients informed by nurses and those who had not had a previous related admission, reported lower scores for comprehension and relationship. In conclusion, the process of obtaining informed refusal was relatively satisfactory except for levels of information disclosure. To improve current practices, Iranian patients need to be better informed about; different treatment options, consequences of treatment refusal, costs of not continuing treatment and follow-ups after refusal. Developing more informative refusal forms is needed. (shrink)

Information and Communications Technologies (ICTs) open up the possibility of new forms of relationship and engagement, which form part of the sociality of modern society, leading some to characterize this as a transition to an "information society", a "network society", or a "third industrial revolution". This has implications for Social Quality, especially in terms of social cohesion, social inclusion and social empowerment. Drawing upon recent research we find that ICTs have added new dimensions to social life in (...) ways that go beyond the original formulations of the digital divide. Conversely, Social Quality can also add important insights into our understanding of the relationship between society and technology. The article argues that discussions of Social Quality should take these dimensions into account. (shrink)

Audits of the informed consent process are a key element of a clinical research quality assurance program. A systematic approach to such audits has not been described in the literature. In this paper we describe two components of the audit. The first is the audit of the informed consent document to verify adherence with federal regulations. The second component is comprised of the audit of the informed consent conference, with emphasis on a real time review of the appropriate communication (...) of the key elements of the informed consent. Quality measures may include preparation of an informed consent history log, notes to accompany the informed consent, the use of an informed consent feedback tool, and the use of institutional surveys to assess comprehension of the informed consent process.

As global warming becomes increasingly prominent, countries worldwide advocate for a low-carbon economy to cope with the pressure to reduce greenhouse gas emissions. The Chinese government has proposed a “dual carbon” goal of peaking carbon emissions by 2030 and becoming carbon neutral by 2060. The disclosure of carbon information by Chinese enterprises has attracted widespread attention from society. This study selects the constituents of the Social Responsibility Index of China Shanghai Stock Exchange from 2016 to 2020 as samples to (...) empirically analyze the relationship between the level of carbon information disclosure and corporate value, and the moderating effect of greenwashing behavior. Results indicated that the quality of carbon disclosure is positively correlated with the enterprise value. Greenwashing behavior promotes the positive impact of carbon disclosure quality on enterprise value in the short run, but this promoting effect fades in the long run. We further found that the carbon information disclosure of non-heavy-pollution enterprises has a more obvious positive impact on enterprise value than that of heavily polluting enterprises. Additionally, the positive impact of carbon information disclosure on enterprise value is more visible among enterprises in a good legal environment than those in a poor legal environment. This study enriches the relevant literature on carbon information disclosure and enterprise “greenwashing” behavior and has practical significance for promoting China’s low-carbon development in the context of ecological civilization and improving the enthusiasm for the quality of enterprise carbon information disclosure.

Background Adherence to ethical guidelines and regulations and protecting and respecting the dignity and autonomy of participants by obtaining a valid informed consent form (ICF) prior to participation in research are crucial; The subjects did not add signatures next to the corrections made to signatures or dates on the ICF, Multiple signatures in other fields, ICF missing/missing signature, Incorrect ICF version Signed after modification, Correction tape used to correct signature, Impersonated signature, Non-research-member signature, however, ICFs are often not properly completed, (...) which must be addressed. This study analyzed ICF signing errors and implemented measures to reduce or prevent these errors. Methods We used the plan–do–check–act (PDCA) cycle to help improve the correctness and validity of ICF signing. Results Interim and final reports from January 2016 to February 2020 including 363 ICFs were studied. The total proportion of correct ICF signatures (200, 83.3%) following the PDCA intervention was significantly higher than that before the intervention (P < 0.05). Analysis of the types of signing error demonstrated that signature errors were significantly reduced after the intervention, particularly for subjects did not add signatures next to the corrections made to signatures or dates on the ICF (16, 6.7%) and impersonated signature (0; P < 0.05). Conclusions The proportions of other error types—multiple signatures in other fields, missing or unsigned ICF, incorrect signature order, incorrect ICF version, use of correction tape to correct signature, and non-medical profession members signing the ICF—did not differ significantly.

The process of obtaining informed consent continues to be a contentious issue in clinical and public health research carried out in resource-limited settings. We sought to evaluate this process among human research participants in randomly selected active research studies approved by the School of Medicine Research and Ethics Committee at the College of Health Sciences, Makerere University.

In order to facilitate the informed consent process, we suggest recording it. If investigators routinely recorded the consent process—including subsequent testing of participants’ comprehension and reeducation efforts—they could monitor the consent practices of their staff and determine what changes in procedure may be needed. In addition, should the adequacy of consent ever be challenged , investigators would have an easily accessible record of what had transpired. And finally, a pool of data would be created that could be accessed by researchers (...) who study informed consent issues and are interested in identifying ways of further improving the process.

In a sample of 615 Belgians a model for fair trade buying behaviour was developed. The impact of fair trade knowledge, general attitudes towards fair trade, attitudes towards fair trade products, and the perception of the quality and quantity of fair trade information on the reported amount of money spent on fair trade products were assessed. Fair trade knowledge, overall concern and scepticism towards fair trade, and the perception of the perceived quantity and quality of fair trade (...) information, influence buying behaviour directly and indirectly through product attitudes. Interest in fair trade products, price acceptability and product liking have a significant impact on fair trade buying behaviour. Product interest is the most important variable influencing buying behaviour. Implications for the campaigns of governments and for the marketing strategy of fair trade organisations are offered.

This paper investigates the socio-technical construction, quality control, and coordination of the credence quality attribute “halal” throughout the halal meat chain. The paper is framed within Actor-Network Theory and economic Conventions Theory. Islamic dietary laws or prescriptions, and how these are translated into production and processing standards using a HACCP-like approach, are discussed. Current halal quality coordination is strongly based on civic and domestic logics in which Muslim consumers prefer transacting with Muslim butchers, that is, individuals of (...) known reputation with similar moral and religious obligations. The HACCP-like approach with identification of critical halal control points, as presented in this paper, fits with the industrial quality convention mechanism and ideally yields guaranteed and trustworthy halal credence quality, eventually marked by a halal meat label. The socio-technical construction of halal credence quality, for example with respect to ritual slaughter, and the quality coordination mechanism aimed at reducing halal quality uncertainty among Muslim consumers, for example through labeling, are identified as key attention points in the future research agenda.

The purpose of this study is to identify the requirements of computerized Management Information Systems and their role in improving the quality of administrative decisions in the Palestinian Ministry of Education and Higher Education. The authors used the descriptive analytical method and the questionnaire method to collect the data.

The study showed a number of results, the most important (...) of which are: There exist a role for computerized management information system requirements in improving the quality of administrative decisions in the Ministry of Education and Higher Education. This result is due to the existence of the support and attention by the senior management in the Ministry of Education and Higher Education by 65.06%, the physical requirements available for the use of computerized Management Information Systems are available by (72.19%), and the software requirements for the use of computerized Management Information Systems are available at 67.74%. The results found that the human requirements available for the use of computerized Management Information Systems are available at (68.33%). The results showed that the organizational requirements that assist in the use of information systems are available at (64.19%). There are no statistically significant differences between respondents' responses to the role of computerized management information system requirements in improving the quality of administrative decisions in the Ministry of Education and Higher Education attributable to the variables(Gender, academic qualification, age, career level), while there are statistically significant differences in the role of computerized management information system requirements in improving the quality of administrative decisions in the Ministry of Education and Higher Education due to variable years of service. The study concluded that the Ministry of Education and Higher Education is able to cope with the external environmental changes rapidly and the limited time available for the collection and analysis of information. This means that administrative information systems should be used by increasing the approval of senior management on Management Information Systems in making their decisions, and to involve the employees in making any change and keep abreast of technical developments and try to use external bodies to advise in the field of computerized information systems, and work to increase coordination between the different departments of the ministry.

BackgroundThe issue of stigma is very important in the battle against HIV/aids in Africa since it may affect patient attendance at healthcare centres for obtaining antiretroviral medications and regular medical check-ups. Stigmatization creates an unnecessary culture of secrecy and silence based on ignorance and fear of victimization. This study was designed to determine if there is external stigmatization of people living with HIV and AIDS by health care workers at a tertiary hospital in KwaZulu-Natal province, South Africa. The study investigated (...) the impact of knowledge of HIV/aids by HCWs on treatment of patients, as well as the comfort level and attitude of HCWs when rendering care to PLWHA.MethodsA descriptive cross sectional study was designed to collect data using an anonymous self-administered structured questionnaire from 334 HCWs. The study was conducted in clinical departments of a large multidisciplinary 922-bed tertiary care teaching hospital in Durban, KZN.ResultsOverall HCWs had an above average knowledge about HIV/aids although some gaps in knowledge were identified. Tests of statistical significance showed that there was association between level of education and knowledge of HIV/aids ; occupation and knowledge of HIV/aids ; and gender and knowledge of HIV/aids. Test for comfort level was only significant for gender, with males showing more comfort and empathy when dealing with PLWHA. The study also revealed that patients were sometimes tested for HIV without informed consent before surgery, due to fear of being infected, and there was some gossiping about patients' HIV status by HCWs, thereby compromising patient confidentiality. The majority of HCWs showed a willingness to report incidents of stigmatization and discrimination to higher authorities, for better monitoring and control.ConclusionsAlthough knowledge, attitude and comfort level of HCWs taking care of PLWHA was above average, enforcement of existing antidiscrimination laws and continuing education in medical ethics and healthcare law, would greatly improve the performance of HCWs taking care of PLWHAs. More psychological support and counselling should be provided to HCWs, to further reduce the impact of stigmatization and discrimination against PLWHA. (shrink)

When someone encounters an explanation perceived as weak, this may lead to a feeling of deprivation or tension that can be resolved by engaging in additional learning. This study examined to what extent children respond to weak explanations by seeking additional learning opportunities. Seven‐ to ten‐year‐olds (N = 81) explored questions and explanations (circular or mechanistic) about 12 animals using a novel Android tablet application. After rating the quality of an initial explanation, children could request and receive additional (...) class='Hi'>information or return to the main menu to choose a new animal to explore. Consistent with past research, there were both developmental and IQ‐related differences in how children evaluated explanation quality. But across development, children were more likely to request additional information in response to circular explanations than mechanistic explanations. Importantly, children were also more likely to request additional information in direct response to explanations that they themselves had assigned low ratings, regardless of explanation type. In addition, there was significant variability in both children's explanation evaluation and their exploration, suggesting important directions for future research. The findings support the deprivation theory of curiosity and offer implications for education. (shrink)

This paper presents a conceptual model for describing the role of information systems in a Total Quality Management (TQM) organization and contrasts it with one for a traditional business firm.

This paper suggests that TQM introduces changes in the firm’s feedback loop and creates new requirements for the IS function. The TQM system model is also (...) used for analyzing and comparing TQM with business reengineering. (shrink)

Background In the last years, there has been an increase in publication of systematic reviews of normative literature or of normative information in bioethics. The aim of a systematic review is to search, select, analyse and synthesise literature in a transparent and systematic way in order to provide a comprehensive and unbiased overview of the information sought, predominantly as a basis for informed decision-making in health care. Traditionally, one part of the procedure when conducting a systematic review is (...) an appraisal of the quality of the literature that could be included. Main text However, while there are established methods and standards for appraising e.g. clinical studies or other empirical research, quality appraisal of normative literature in the context of a systematic review is still rather a conundrum – not only is it unclear how it could or should be done, but also the question whether it necessarily must be done is not settled yet. Based on a pragmatic definition of “normative literature” as well as on a typology of different types of systematic reviews of normative literature/information, this paper identifies and critically discusses three possible strategies of conducting quality appraisal. Conclusions The paper will argue that none of the three strategies is able to provide a general and satisfying solution to the problems associated with quality appraisal of normative literature/information. Still, the discussion of the three strategies allows outlining minimal conditions that elaborated strategies have to meet in future, and facilitates sketching a theoretically and practically promising strategy.

Air pollution is one of the largest environmental health risks globally but is often imperceptible to people. Air quality smartphone applications provide real-time localized air quality information and have the potential to help people learn about the health effects of air pollution and enable them to take action to protect their health. Hundreds of air quality apps are now available; however, there is scant information on how effective these mobile apps are at educating stakeholders about (...) air pollution and promoting behavioral change to protect their health. In this paper, we test how intrinsic and extrinsic motivations can enhance users’ engagement with air quality information through an app, and favor changes in protective behavior. We developed an air quality app, AirForU, with a built-in research study that was downloaded by 2740 users. We found that engagement was higher for users with intrinsic motivations, such as those who are health conscious, either because they are suffering from heart disease or other conditions aggravated by air pollution, or because they exercise frequently and want to maintain a healthy lifestyle. Extrinsic motivations such as notifications were also effective. App users stated that they frequently shared air quality information with others, learned about the Air Quality Index, and took measures to protect their health while using AirForU app. (shrink)

In many coevolutionary systems members of one party select members of a second party based on quality differences existing among members of the latter (e.g., predators and prey, pollinators and flowers, etc.). We examined the fate of characters that increase (amplifiers) or decrease (attenuators) the perceived amplitude of differences in the quality upon which choice of the selecting party is based. We found that the evolution of such characters depends on (i) the relationship between the cost of the (...) character and the relative benefit it gives to the high quality individuals (if an amplifier) or low quality individuals (if an attenuator), and (ii) the frequency, among members of the selected party, of the quality sought by the selecting party.

Zu den elementaren Rechtfertigungsbedingungen der medizinischen Forschung an und mit Menschen zählt die informierte Einwilligungserklärung („informed consent“) des Probanden/Patienten. Für die Gewährleistung eines „informed consent“ sind dem potenziellen Studienteilnehmer u. a. qualitativ hochwertige schriftliche Aufklärungsmaterialien zur Verfügung zu stellen. Wir entwickelten eine Liste von Prüfpunkten, um mit ihnen die Qualität schriftlicher Aufklärungsmaterialien zu bestimmen und zu bewerten. Mithilfe eines Kriterienkataloges bestehend aus über 100 Prüfpunkten wurde die Qualität von 128 zufällig ausgewählten schriftlichen Aufklärungsmaterialien zu Forschungsvorhaben beurteilt, die der Ethikkommission der (...) Universität zu Lübeck im Jahr 2006 vorgelegt worden waren. Jeder Prüfpunkt ist einem von sechs Qualitätsbereichen zugeordnet (z. B. Lesbarkeit und Verständlichkeit, Nutzen-/Schadenpotenziale). Die untersuchten Aufklärungsmaterialien erfüllten im Durchschnitt die Hälfte der 117 abgefragten Qualitätskriterien, die Spannweite reichte dabei von 20 % bis 76 %. Der höchste Qualitätsscore wurde für den Bereich „Einwilligungserklärung“ beobachtet (64 % der Kriterien erfüllt), am schlechtesten schnitt der Bereich „Nutzen- und Schadenpotenziale“ ab (35 % der Kriterien erfüllt). Aufklärungsmaterialien zu klinischen Prüfungen von Arzneimitteln zeigten dabei eine signifikant höhere Qualität als die Aufklärungsmaterialien zu anderen Studientypen. Nur 21 der 117 analysierten Qualitätskriterien wurden in mehr als 80 % der einschlägigen Aufklärungsmaterialien umgesetzt. Die vorliegende Arbeit zeigt deutliche Defizite in der Qualität der untersuchten Aufklärungsmaterialien auf. Forscherinnen und Forscher benötigen Hilfestellung bei der Erstellung von Materialien, die eine informierte Entscheidung für oder gegen eine Studienteilnahme ermöglichen.

This paper explores the problem of knowledge in computational informational organisms, i.e. organisms that include a computing machinery at the artifact side. Although information can be understood in many ways, from the second half of the past century information is getting more and more digitised, von Neumann machines becoming dominant. Computational information is a challenge for the act of measuring, as neither purely quantitative nor totally qualitative approaches satisfy the need to explain the interplay among the agents (...) producing and managing computational information. In this paper, Floridi’s method of levels of abstraction is applied to the analysis of computational information, with a chief interest in the concepts of information measure, quantification and quality.

By using instrumentation initially designed for counting white blood cells, sperm counts have been utilized by clinicians since 1929, particularly to evaluate cases of suspected infertility. Although this basic biological parameter might be assumed to be stable over time, several studies over the past 20 years have suggested a decline in sperm count or density. The most controversial of these analyses was published in 1992. A flood of criticism followed this analysis of 61 studies that found a 50% decline in (...) sperm density between 1938 and 1990. Critics suggested that historical methods (of counting sperm or conducting studies) were variable and unreliable, differing from modern methods both qualitatively and quantitatively. To address this issue we analyzed these studies for trends in counting methods or their variability. We found neither. Alternative analyses produced some differences in trend estimates, but statistical factors alone could not account for the total decline in sperm density. We reviewed study populations to identify trends in population characteristics, such as abstinence time, that might explain the decline. However, controlling analytically for such factors only increased the rate of decline. We conclude that historical data on sperm density, despite large random error, are surprisingly reliable. Nonetheless, understanding causes of temporal and geographic differences in sperm density must await contemporary data. BioEssays 21:614–621, 1999. © 1999 John Wiley & Sons, Inc. (shrink)
