Response to “Six Provocations for Big Data,” Boyd and Crawford (2011)

3 minute read

Setting the guidelines for the social, political and human consequences of research in the database age is an issue that has yet to be fully explored. On one hand, the champions of publicness and digital democracy argue for absolute transparency and data freedom. On the other, privacy advocates consistently take issue with what they see as a potential threat to individual liberty. In their 2011 paper “Six Provocations for Big Data,” Danah Boyd and Kate Crawford attempt to bridge this divide by laying out the basic principles of  what they call ‘Big Data,’ as well as a broad set of principles that should guide researchers seeking to harness the power of that data for social good.

Perhaps most importantly, Boyd and Crawford enumerate the basic misassumption that researchers, academics and media professionals often make when interpreting Big Data: they treat data as an objective and infallible source of knowledge when it is really just a piece of the underlying story. Numbers do not speak for themselves, so we must adapt our methods of research to the demands of new technology. As Latour puts it, “Change the instruments, and you will change the entire social theory that goes with them.”

Response to Tufte, “Data Analysis for Politics and Policy”

4 minute read

In the first chapter of his book Data Analysis for Politics and Policy, Yale researcher Edward R. Tufte demonstrates the opportunities as well as the challenges of using data to help inform decisions of public policy. First, Tufte sets forth the various terms and theoretical frameworks he will be using to analyze data. He advocates the use of what he calls a "multivariate analysis" which takes into account several describing variables to understand a problem rather than just one. In scientific settings, it is possible to isolate a single describing (independent) variable from others and provide a control by which to reach a conclusion regarding the cause of a given response (dependent) variable. But in the real world of social problems and political policy, it is often impossible to parse out the effects of the multitude of possible describing variables that may be at play in a given situation. For Tufte, that gives rise to the need for a "statistical technique" that "may help organize or arrange the data so that the numbers speak more clearly to the question of causality." The numbers cannot answer the question of causality, but they can help shed light on it if they are analyzed in such a way that takes into account as many different variables as possible.

 

Data visualization, infographic or illustration?

3 minute read

Check out this interactive graphic on the rise of Google recently produced by the folks over at OnlinePhD.org. It's an innovative example of how developers can use a responsive, single-page interface to convey a broad range of chronological information that would otherwise be crammed into a timeline. The interactivity of the graphic compels the user to click through to see what happens next, and provides a more engaging narrative than a simple linear flow would.

Based upon our various understandings of the terms data visualization, infographic and illustration, which category would this graphic fall into? I'd be most inclined to say it's an infographic rather than an illustration, given that its primary goal is to convey factual information (the chronological rise of Google) rather than just to provide an illustration, which it also does quite nicely. But I wouldn't call it a data visualization, because it's not immediately apparent from first glance what the graphic is trying to illustrate, and the story isn't data-driven. It has a more conventional narrative.

Response to Ayres and Sweller, "The Split Attention Principle in Multimedia Learning"

Paul Ayres and John Sweller apply the split-attention principle to the design of multimedia instruction, asserting that it is "important to avoid formats that require learners to split their attention between, and mentally integrate, multiple sources of information" (135). This assertion is based on the theory of cognitive load, which refers to the amount of information the brain is able to process at any given point in time. The greater the number of sources of information in multimedia design, the higher the cognitive load required to understand it. An "extraneous" cognitive load, as Ayres and Sweller diagnose it, hinders the learning process by requiring users to split their attention and "mentally integrate the multiple sources of information" (135). As such, it is often necessary for the designer of a piece of multimedia instruction to do as much as possible to present the multiple sources of information in an integrated format.

With practice and expertise, the brain can be taught to expedite the process of piecing together disparate sources of information without need for additional visual aids, such as the algebra student being able to readily identify angle measures of a given shape. But for the novice learner, "substantial cognitive resources will need to be devoted to splitting attention between the disparate sources of information and mentally integrating them" (137). As a way to lessen the cognitive load, then, designers can employ visual cues or "referrents" that help integrate multiple sources of information. Other ways to help learners piece together multiple information sources is what Ayers and Sweller call the "dual mode" of multimedia design, which refers to the use of two different sensory cues, usually sight and sound, to lessen the cognitive load.

Response to Donald Norman, The Design of Everyday Things

In The Design of Everyday Things, Donald Norman looks at the design of familiar items to explain how to construct effective visual aids. At the heart of all user-friendly designs, Norman asserts, lies two fundamental components: a good "conceptual model" and a logical "visible structure" (13). An effective conceptual model should allow us to predict the outcome of our actions by explaining how an item works in a theoretical manner. Ideally, conceptual models should be as simple as possible, but the presiding imperative must always be accuracy and clarity of explanation. The item itself must also employ a logical visual structure, including the intuitive use of what Norman calls affordances, constraints and mappings. It should be clear to the eye from visual cues what an item can do (its affordances), what it can't do (its constraints) and how to connect the various parts together to perform an operation (mapping).

Response to Wolfe, Visual Search

Jeremy M. Wolfe lays out the basic principles of visual search, shedding light on the often unconscious ways our brains process sensory information based upon certain visual cues. Perhaps most importantly, Wolfe defines the basic structural features of visual search, including color, orientation, motion, size and scale. While many such basic features may appear obvious, Wolfe goes a step further in pointing out the various psychological factors that can come into play in our processing of visual information. For example, in keeping with Plato's idea of forms, Wolfe asserts that an object is more than just the sum of its parts; it is an object in its own right. As soon as attention arrives, Wolfe contends, "an object is not seen as collections of features. It  is an object having certain featural attributes." An object carries with it certain mental associations that change the way users perceive it.

On Narrow-Minded Conceptions of What Makes One a “Journalist”

10 minute read

What constitutes a 'journalist' is a semantic debate I've had dozens of times, particularly in grad school and in my previous full-time job as "Digital Media Manager" (another vague term) at Savannah Morning News. Outside of professional spheres, though, the general public discourse goes something like this:

Random person: So tell me again: Where do you work?

Me: At [Insert Publication Name Here].

Random person: 'Oh, cool! So you're a reporter. What do you write or cover? [insert slight tone of self-righteousness from random person knowing now she makes more than me].

Me: Well, I write code.

Random person: So you're a developer?

Me: Yeah, in a way, but I build news apps and data projects for editorial purposes, so I'm a journalist, too.

Random person: 'Oh...."

Typography, design as discourse

In his essay on text and typography, Lupton touches on the fundamental ideological shift of the digital era: that "the dominant subject is neither reader nor writer but user, a figure conceived as a bundle of words and impairments" (73). In other words, we cannot continue to view the way we communicate with audiences in a traditional, two-dimensional form where only the information we communicate is important. We have to think about how it will be perceived by others. As designers, we cannot simply apply our own artistic sensibilities to the material we produce. We must always keep the user in mind. In the case of typography, this user-centric approach requires what Katherine McCoy calls "redefining typography as discourse." Design is more than a work of authorship. It is a work of communication that challenges "readers to produce their own meanings while also to elevate the status of the designer within the process of authorship" (73). Simply put, design is a conversation, not a sermon.

Response to Manovich on the Database

Manovich crystallizes the nature of the database-driven story and its applications to new media by describing them both as essentially dissolutions of the conventional narrative form. Stories told in database form need not follow a linear narrative structure with a beginning, middle and an end. Instead they are what Manovich calls "collections of individual items, with every item possessing the same significance as the other" (218). For Manovich, this database-driven story might take the form of a Twitter stream, which allows stories to be conveyed in small bits rather than packaged into a predefined narrative. But he also makes sure to address the potential pitfalls of this sort of database-driven story: that we  may "have too much information and too few narrative that can tie it all together"; that we may have too many Tweets but no logical or convenient manner of piecing them into a usable format (217). Finding a balance between the competing impulses of  information and narrative, then, leads Manovich to his undergirding call to action: We must devise a system of what he calls "info-aesthetics," a sort of theoretical framework that helps us marry the aesthetic component of information access (i.e. the database-driven model) with the aesthetic components of processing or filtering that help us turn raw information into a coherent fashion (217).

Miss Molly trolley destroyed by flames

Trolley bursts into flames just moments after dropping off students - Link to story on MercerCluster.com

One of Mercer’s two student trolleys inexplicably burst into flames early Friday morning just moments after dropping off its last load of passengers at Greek Village.

The driver of the iconic “Miss Molly” trolley was traveling north on Stadium Drive near the University Center around 3:30 a.m. when he noticed smoke coming from the vehicle’s rear engine. He immediately pulled over and called 911, but the flames had spread too quickly for the trolley to be salvaged.

No students were injured in the incident, and the driver escaped from the smoldering vehicle unscathed.

Chief Gary Collins with the Mercer Police department said officers arrived at the scene within five minutes to find Miss Molly almost totally destroyed.

“Miss Molly didn’t make it out alive. When we got there, the trolley was smoking and you could still see some flames. What damage the fire didn’t do, the smoke and water did,” Collins said. “It was awful.”

NewTown Macon owns and operates the trolley service through a contract with the University.

NewTown spokesman Hal Baskin said it appears the fire started in the trolley’s rear engine, but the exact cause of the incident won’t be determined until insurance inspectors can conduct a full investigation next week.

Baskin said he does not believe the fire was caused by a manufacturer’s defect, or that students should have any reason to be fearful of using the trolley service in the future.

“I would expect that this is an isolated incident and not a problematic issue that affects all trolleys . . it was just something that happened,” Baskin said.

Investigators do not suspect foul play was involved in the incident.

NewTown has already begun making plans to replace Miss Molly with a new trolley.

“We’re looking at what other equipment is available to replace Miss Molly, and we’re just waiting to hear back from our insurance inspectors at this point,” Baskin said.

NewTown will continue to provide service in the meantime using its other trolley, “Sweet Melissa,” which is the same model trolley as Miss Molly. Baskin said Sweet Melissa was undergoing precautionary safety inspections on Tuesday to ensure that it is safe to operate.

The student trolley service to downtown should continue as scheduled this week, with Sweet Melissa shifted into full rotation for the time being, Chief Collins said.

“I’m just so grateful that no one was hurt. It could have been worse. I don’t think there’s any reason to worry, though. These sorts of things happen from time to time,” Collins said.

Collins added that he hopes the incident will remind students to remain vigilant and orderly while using the trolley service.

Dean of students Doug Pearson told The Cluster Tuesday afternoon that he’s not sure yet if the incident will have any significant impact on student trolley services in the future.

“It’s possible that because there’s only one trolley for now that there could be minor disruptions in service in the coming weeks. Obviously, we’ll notify students of any schedule changes via email and Bear Blurbs as soon as they happen,” Pearson said.

Miss Molly was purchased by the Macon Transit Authority in 2001 at a price tag of $127,000, then later sold to NewTown Macon for $160,000 in 2004. It had an estimated capacity of 40 people, and had been used in recent years to to give daytime tours of local historic sites as well as transport students to downtown Macon at night.

The trolley was named after Macon-born musician Little Richard’s 1958 hit song, “Good Golly Miss Molly.”
