    Although photographic assessment has been found to be reliable in assessing hair loss in Trichotillomania, the validity of this method is unclear, particularly for gauging progress in treatment. The current study evaluated the psychometric properties of photographic assessment of change in Trichotillomania. Photographs showing hair loss of adults with Trichotillomania were taken before and after participating in a clinical trial for the condition. Undergraduate college students (N = 211) rated treatment response according to the photos, and additional archival data on hair pulling severity and psychosocial health were retrieved from the clinical trial. Photographic assessment of change was found to possess fair reliability (ICC = 0.53), acceptable criterion validity (r = 0.51), good concurrent validity (r = 0.30–0.36), and excellent incremental validity (ΔR2 = 8.67, p \u3c 0.01). In addition, photographic measures were significantly correlated with change in quality of life (r = 0.42), and thus could be considered an index of the social validity of Trichotillomania treatment. Gender of the photo rater and pulling topography affected the criterion validity of photographic assessment (partial η2 = 0.05–0.11). Recommendations for improving photographic assessment and future directions for hair pulling research are discussed

    Data Privacy and Dignitary Privacy: Google Spain, the Right To Be Forgotten, and the Construction of the Public Sphere

    Get PDF
    The 2014 decision of the European Court of Justice in Google Spain controversially held that the fair information practices set forth in European Union (EU) Directive 95/46/EC (Directive) require that Google remove from search results links to websites that contain true information. Google Spain held that the Directive gives persons a “right to be forgotten.” At stake in Google Spain are values that involve both privacy and freedom of expression. Google Spain badly analyzes both. With regard to the latter, Google Spain fails to recognize that the circulation of texts of common interest among strangers makes possible the emergence of a “public” capable of forming the “public opinion” that is essential for democratic self-governance. As the rise of American newspapers in the nineteenth and twentieth centuries demonstrates, the press underwrites the public sphere by creating a structure of communication both responsive to public curiosity and independent of the content of any particular news story. Google, even though it is not itself an author, sustains the contemporary virtual public sphere by creating an analogous structure of communication. With regard to privacy values, EU law, like the laws of many nations, recognizes two distinct forms of privacy. The first is data privacy, which is protected by the fair information practices contained in the Directive. These practices regulate the processing of personal information to ensure (among other things) that such information is used only for the specified purposes for which it has been legally gathered. Data privacy operates according to an instrumental logic, and it seeks to endow persons with “control” over their personal data. Data subjects need not demonstrate harm in order to establish violations of data privacy. The second form of privacy recognized by EU law is dignitary privacy. Article 7 of the Charter of Fundamental Rights of the European Union protects the dignity of persons by regulating inappropriate communications that threaten to degrade, humiliate, or mortify them. Dignitary privacy follows a normative logic designed to prevent harm to personality caused by the violation of civility rules. There are the same privacy values as those safeguarded by the American tort of public disclosure of private facts. Throughout the world, courts protect dignitary privacy by balancing the harm that a communication may cause to personality against legitimate public interests in the communication. The instrumental logic of data privacy is inapplicable to public discourse, which is why the Directive contains derogations for journalistic activities. The communicative action characteristic of the public sphere is made up of intersubjective dialogue, which is antithetical both to the instrumental rationality of data privacy and to its aspiration to ensure individual control of personal information. Because the Google search engine underwrites the public sphere in which public discourse takes place, Google Spain should not have applied fair information practices to Google searches. But the Google Spain opinion also invokes Article 7, and in the end the decision creates doctrinal rules that are roughly approximate to those used to protect dignitary privacy. The Google Spain opinion is thus deeply confused about the kind of privacy it wishes to protect. It is impossible to ascertain whether the decision seeks to protect data privacy or dignitary privacy. Google Spain is ultimately pushed in the direction of dignitary privacy because data privacy is incompatible with public discourse, whereas dignitary privacy may be reconciled with the requirements of public discourse. Insofar as freedom of expression is valued because it fosters democratic self-government, public discourse cannot serve as an effective instrument of self-determination without a modicum of civility. Yet the Google Spain decision recognizes dignitary privacy only in a rudimentary and unsatisfactory way. If it had more clearly focused on the requirements of dignitary privacy, Google Spain would not so sharply have distinguished Google links from the underlying websites to which they refer. Google Spain would not have blithely outsourced the enforcement of the right to be forgotten to a private corporation like Google

    Fertility and its Meaning: Evidence from Search Behavior

    Full text link
    Fertility choices are linked to the different preferences and constraints of individuals and couples, and vary importantly by socio-economic status, as well by cultural and institutional context. The meaning of childbearing and child-rearing, therefore, differs between individuals and across groups. In this paper, we combine data from Google Correlate and Google Trends for the U.S. with ground truth data from the American Community Survey to derive new insights into fertility and its meaning. First, we show that Google Correlate can be used to illustrate socio-economic differences on the circumstances around pregnancy and birth: e.g., searches for "flying while pregnant" are linked to high income fertility, and "paternity test" are linked to non-marital fertility. Second, we combine several search queries to build predictive models of regional variation in fertility, explaining about 75% of the variance. Third, we explore if aggregated web search data can also be used to model fertility trends.Comment: This is a preprint of a short paper accepted at ICWSM'17. Please cite that version instea

    Platforms, the First Amendment and Online Speech: Regulating the Filters

    Get PDF
    In recent years, online platforms have given rise to multiple discussions about what their role is, what their role should be, and whether they should be regulated. The complex nature of these private entities makes it very challenging to place them in a single descriptive category with existing rules. In today’s information environment, social media platforms have become a platform press by providing hosting as well as navigation and delivery of public expression, much of which is done through machine learning algorithms. This article argues that there is a subset of algorithms that social media platforms use to filter public expression, which can be regulated without constitutional objections. A distinction is drawn between algorithms that curate speech for hosting purposes and those that curate for navigation purposes, and it is argued that content navigation algorithms, because of their function, deserve separate constitutional treatment. By analyzing the platforms’ functions independently from one another, this paper constructs a doctrinal and normative framework that can be used to navigate some of the complexity. The First Amendment makes it problematic to interfere with how platforms decide what to host because algorithms that implement content moderation policies perform functions analogous to an editorial role when deciding whether content should be censored or allowed on the platform. Content navigation algorithms, on the other hand, do not face the same doctrinal challenges; they operate outside of the public discourse as mere information conduits and are thus not subject to core First Amendment doctrine. Their function is to facilitate the flow of information to an audience, which in turn participates in public discourse; if they have any constitutional status, it is derived from the value they provide to their audience as a delivery mechanism of information. This article asserts that we should regulate content navigation algorithms to an extent. They undermine the notion of autonomous choice in the selection and consumption of content, and their role in today’s information environment is not aligned with a functioning marketplace of ideas and the prerequisites for citizens in a democratic society to perform their civic duties. The paper concludes that any regulation directed to content navigation algorithms should be subject to a lower standard of scrutiny, similar to the standard for commercial speech

    Big Data as a Technology-to-think-with for Scientific Literacy

    Get PDF
    This research aimed to identify indications of scientific literacy resulting from a didactic and investigative interaction with Google Trends Big Data software by first-year students from a high-school in Novo Hamburgo, Southern Brazil. Both teaching strategies and research interpretations lie on four theoretical backgrounds. Firstly, Bunge's epistemology, which provides a thorough characterization of Science that was central to our study. Secondly, the conceptual framework of scientific literacy of Fives et al. that makes our teaching focus precise and concise, as well as supports one of our methodological tool: the SLA (scientific literacy assessment). Thirdly, the "crowdledge" construct from dos Santos, which gives meaning to our study when as it makes the development of scientific literacy itself versatile for paying attention on sociotechnological and epistemological contemporary phenomena. Finally, the learning principles from Papert's Constructionism inspired our educational activities. Our educational actions consisted of students, divided into two classes, investigating phenomena chose by them. A triangulation process to integrate quantitative and qualitative methods on the assessments results was done. The experimental design consisted in post-tests only and the experimental variable was the way of access to the world. The experimental group interacted with the world using analyses of temporal and regional plots of interest of terms or topics searched on Google. The control class did 'placebo' interactions with the world through on-site observations of bryophytes, fungus or whatever in the schoolyard. As general results of our research, a constructionist environment based on Big Data analysis showed itself as a richer strategy to develop scientific literacy, compared to a free schoolyard exploration.Comment: 23 pages, 2 figures, 8 table

    Get PDF
    Aim: This article reports the results of an analysis of the content of national and international professional guidance on social media for the nursing profession. The aim was to consolidate good practice examples of social media guidelines, and inform the development of comprehensive guidance. Method: A scoping search of professional nursing bodies’ and organisations’ social media guidance documents was undertaken using google search. Results: 34 guidance documents were located, and a content analysis of these was conducted. Conclusion: The results, combined with a review of competency hearings and literature, indicate that guidance should cover the context of social media, and support nurses to navigate and negotiate the differences between the real and online domains to help them translate awareness into actions

    Approaching Transhumanism: On How Human Beings Transform in the 21st Century

    Get PDF
    The following article is to introduce the reader into a cultural and intellectual movement whose aim is to identify the need for improvement in human life in the sphere of physicality as well as mentality with the aid of modern technologies – transhumanism. With the dramatic change in the perception of technology, transhumanist welcome the opportunity to improve cognitive skills, help to perpetuate human happiness, or increase longevity. Although the opponents of the transhumanist thought dismiss it as “the world’s most dangerous idea,” the adversaries advocate that the alternation of human form is both practical and reasonable. With the use of modern technology, enthusiasts of transhumanism try to prove that the human body needs to be re-invented in order to transcend the natural limitations. In my work I will try to tackle the problem of human body being currently subject to gradual transition from Homo Sapiens to Robo Sapiens, the process of ‘becoming’ a cyborg. By incorporating bodily augmentation, contemporary artists such as Stelarc or Neil Harbisson cast a light on the change of physical form, as well as the definition of being human. Evoking much controversy, transhumanism brings a completely new dimension to the understanding of the current human condition

    The vulnerable subject

    Get PDF
    Academic freedom is formally supported but often challenged, through activities like no-platforming and through a sentiment of sensitivity and an understanding that ideas can be harmful. This development is discussed here as a reflection of the rise of the ‘vulnerable subject.’ This paper demonstrates the growing importance of vulnerability as the central human characteristic in (post) modern times and with reference to law and justice practices explains the ‘collapse of the harm principle.’ Developed through Frank Furedi’s theory of diminished subjectivity we will demonstrate the extent to which the vulnerable subject has been institutionalised and adopted as a new (fragmented) norm. Within the framework of diminished subjectivity, the inner logic of vulnerability has a spiralling dynamic—once adopted as a norm, the vulnerable subject’s answer to the question ‘vulnerable to what?’ constantly expands, drawing in ever more areas of life, behaviour, relationships as well as words and ideas into a regulatory framework. Concerns about overcriminalisation are understood here to be a product of this vulnerable subject, something that cannot be resolved at the level of law but must relate to the wider cultural and political sense of human progress and a defence of the robust liberal subject in society
