Information Overload: An Overview

For almost as long as there has been recorded information, there has been a perception that humanity has been overloaded by it. Concerns about 'too much to read' have been expressed for many centuries, and made more urgent since the arrival of ubiquitous digital information in the late twentieth century. The historical perspective is a necessary corrective to the often, and wrongly, held view that it is associated solely with the modern digital information environment, and with social media in particular. However, as society fully experiences Floridi's Fourth Revolution, and moves into hyper-history (with society dependent on, and defined by, information and communication technologies) and the infosphere (a information environment distinguished by a seamless blend of online and offline information actvity), individuals and societies are dependent on, and formed by, information in an unprecedented way, information overload needs to be taken more seriously than ever. Overload has been claimed to be both the major issue of our time, and a complete non-issue. It has been cited as an important factor in, inter alia, science, medicine, education, politics, governance, business and marketing, planning for smart cities, access to news, personal data tracking, home life, use of social media, and online shopping, and has even influenced literature The information overload phenomenon has been known by many different names, including: information overabundance, infobesity, infoglut, data smog, information pollution, information fatigue, social media fatigue, social media overload, information anxiety, library anxiety, infostress, infoxication, reading overload, communication overload, cognitive overload, information violence, and information assault. There is no single generally accepted definition, but it can best be understood as that situation which arises when there is so much relevant and potentially useful information available that it becomes a hindrance rather than a help. Its essential nature has not changed with changing technology, though its causes and proposed solutions have changed much. The best ways of avoiding overload, individually and socially, appear to lie in a variety of coping strategies, such as filtering, withdrawing, queuing, and 'satisficing'. Better design of information systems, effective personal information management, and the promotion of digital and media literacies, also have a part to play. Overload may perhaps best be overcome by seeking a mindful balance in consuming information, and in finding understanding

Reinventing College Physics for Biologists: Explicating an epistemological curriculum

The University of Maryland Physics Education Research Group (UMd-PERG) carried out a five-year research project to rethink, observe, and reform introductory algebra-based (college) physics. This class is one of the Maryland Physics Department's large service courses, serving primarily life-science majors. After consultation with biologists, we re-focused the class on helping the students learn to think scientifically -- to build coherence, think in terms of mechanism, and to follow the implications of assumptions. We designed the course to tap into students' productive conceptual and epistemological resources, based on a theoretical framework from research on learning. The reformed class retains its traditional structure in terms of time and instructional personnel, but we modified existing best-practices curricular materials, including Peer Instruction, Interactive Lecture Demonstrations, and Tutorials. We provided class-controlled spaces for student collaboration, which allowed us to observe and record students learning directly. We also scanned all written homework and examinations, and we administered pre-post conceptual and epistemological surveys. The reformed class enhanced the strong gains on pre-post conceptual tests produced by the best-practices materials while obtaining unprecedented pre-post gains on epistemological surveys instead of the traditional losses.Comment: 35 pages including a 15 page appendix of supplementary material

The Literature of Ag Communication: A Partial View, 1970-1979

Pressures for better access to the literature of agricultural communication are growing, from several directions

Review of “Jurisdictional” Issues Under the Bumpers Amendment

The proposed Bumpers Amendment to the Administrative Procedure Act would encourage courts to be less deferential than they have previously been toward federal agencies\u27 views on issues of law. With regard to jurisdictional questions, the amendment would go further: it would invite courts not only to assert their independence, but also to disfavor agencies\u27 positions. Professor Levin regards this special rule of construction for jurisdictional questions as an attempt to achieve deregulation through judicial review. He criticizes this strategy as poorly conceived and calls attention to several weaknesses in the draftsmanship of the jurisdiction provision

Obscurantism in Academic Writing: What It Is and Why It Is Bad

Obscure academic writing is vague, ambiguous, jargon-filled, or otherwise difficult to interpret. Obscurantists use such writing to hide the shallowness or incoherence of their ideas. There is value in being able to see through their attempts so that one does not waste one’s time on, for example, the psychoanalytic verbiage of Jacques Lacan. Therefore, this article identifies five recognizable characteristics of obscure—and especially of obscurantist—academic writing. Specifically, obscurantists tend to (1) fail to distinguish between truistic and radical versions of their claims, (2) employ paradoxical formulations, (3) avoid giving examples of their ideas (4), overuse abstract nouns, and (5) insist on their own lucidity. The article concludes by suggesting that the deepest problem with obscure academic writing is that it insulates arguments and theories from criticism

From street to screen: Debord’s drifting cinema

This essay offers a new and original way of relating to the drift by positing it not simply as a pedestrian activity, something that occurs on streets and in cities (as the SI wanted) but rather as a practice that can be expressed in celluloid – in the rhythms and syncopations of montage. Through a close analysis of Debord's second film Sur le passage de quelques personnes à travers une assez courte unité de temps (On the Passage of a Few Persons Through a Rather Brief Unity of Time (1959), we argue that this cinematic reading of the drift retains and performs its politics through its capacity to disrupt capitalist modernity's temporal regime. For us, such a regime, as it was for Debord, is predicated on the production of an endless present, in which what matters is how attention is seduced and captured by an expanded notion of the cinematic – the ubiquity of networks of screens, consoles, images and data flows. Faced with the continual refrains of ‘24/7 capitalism’ (Jonathan Crary 2014), it is no longer enough to express political content explicitly and/or to highlight, in Brechtian fashion, the structures of the apparatus. Rather by drawing on (amongst others) the work of Jonathan Beller, Bernard Stiegler, and Michael J. Shapiro, we show how Debord's films retain their relevance in the extent to which their drift-like quality, the irregularity of their rhythms, contests the unspoken choreography of what we call, after Henri Lefebvre, capitalist ‘dressage’. Through its interruptions and stoppages, Debord's cinema, we claim, manages to use the drift as a device for producing memory – the temporal lag that contemporary capital is desperate to erase in order to exhibit its own immediacy as a kind of eternity, the only time worth living

Reasoning in criminal intelligence analysis through an argumentation theory-based framework

This thesis provides an in-depth analysis of criminal intelligence analysts’ analytical reasoning process and offers an argumentation theory-based framework as a means to support that reasoning process in software applications. Researchers have extensively researched specific areas of criminal intelligence analysts’ sensemaking and reasoning processes over the decades. However, the research is fractured across different research studies and those research studies often have high-level descriptions of how criminal intelligence analysts formulate their rationale (argument). This thesis addresses this gap by offering low level descriptions on how the reasoning-formulation process takes place. It is presented as a single framework, with supporting templates, to inform the software implementation process. Knowledge from nine experienced criminal intelligence analysts from West Midlands Police and Belgium’s Local and Federal Police forces were elicited through a semi-structured interview for study 1 and the Critical Decision Method (CDM), as part of the Cognitive Task Analysis (CTA) approach, was used for study 2 and study 3. The data analysis for study 1 made use of the Qualitative Conventional Content Analysis approach. The data analysis for study 2 made use of a mixed method approach, consisting out of Qualitative Directed Content Analysis and the Emerging Theme Approach. The data analysis for study 3 made use of the Qualitative Directed Content Analysis approach. The results from the three studies along with the concepts from the existing literature informed the construction of the argumentation theory-based framework. The evaluation study for the framework’s components made use of Paper Prototype Testing as a participatory design method over an electronic medium. The low-fidelity prototype was constructed by turning the frameworks’ components into software widgets that resembled widgets on a software application’s toolbar. Eight experienced criminal intelligence analysts from West Midlands Police and Belgium’s Local and Federal Police forces took part in the evaluation study. Participants had to construct their rationale using the available components as part of a simulated robbery crime scenario, which used real anonymised crime data from West Midlands Police force. The evaluation study made use of a Likert scale questionnaire to capture the participant’s views on how the frameworks’ components aided participants with; understanding what was going on in the analysis, lines-of-enquiry and; the changes in their level of confidence pertaining to their rationale. A non-parametric, one sample z-test was used for reporting the statistical results. The significance is at 5% (α=0.05) against a median of 3 for the z-test, where μ =3 represents neutral. The participants reported a positive experience with the framework’s components and results show that the framework’s components aided them with formulating their rationale and understanding how confident they were during different phases of constructing their rationale
