There is nothing wrong with a provider usingde-‐identified data for other purposes; privacy statutes, after all, govern PII, not de-‐identified data.
Key point.

Application Modern higher education institutions have unprecedentedly large and detailed collections of data about their students, and are growing increasingly sophisticated in their ability to merge datasets from diverse sources. As a result, institutions have great opportunities to analyze and intervene on student performance and student learning. While there are many potential applications of student data analysis in the institutional context, we focus here on four approaches that cover a broad range of the most common activities: data-based enrollment management, admissions, and financial aid decisions; analytics to inform broad-based program or policy changes related to retention; early-alert systems focused on successful degree completion; and adaptive courseware.
Perhaps even more than other sections, this one recalls the trope:
The difference probably comes from the impact of (institutional) “application”.
-
the risk of re-identification increases by virtue of having more data points on students from multiple contexts
Very important to keep in mind. Not only do we realise that re-identification is a risk, but this risk is exacerbated by the increase in “triangulation”. Hence some discussions about Differential Privacy.
-
the automatic collection of students’ data through interactions with educational technologies as a part of their established and expected learning experiences raises new questions about the timing and content of student consent that were not relevant when such data collection required special procedures that extended beyond students’ regular educational experiences of students
Useful reminder. Sounds a bit like “now that we have easier access to data, we have to be particularly careful”. Probably not the first reflex of most researchers before they start sending forms to their IRBs. Important for this to be explicitly designated as a concern, in IRBs.
-
Responsible Use
Again, this is probably a more felicitous wording than “privacy protection”. Sure, it takes as a given that some use of data is desirable. And the preceding section makes it sound like Learning Analytics advocates mostly need ammun… arguments to push their agenda. Still, the notion that we want to advocate for responsible use is more likely to find common ground than this notion that there’s a “data faucet” that should be switched on or off depending on certain stakeholders’ needs. After all, there exists a set of data use practices which are either uncontroversial or, at least, accepted as “par for the course” (no pun intended). For instance, we probably all assume that a registrar should receive the grade data needed to grant degrees and we understand that such data would come from other sources (say, a learning management system or a student information system).
-
Data sharing over open-source platforms can create ambiguous rules about data ownership and publication authorship, or raise concerns about data misuse by others, thus discouraging liberal sharing of data.
Surprising mention of “open-source platforms”, here. Doesn’t sound like these issues are absent from proprietary platforms. Maybe they mean non-institutional platforms (say, social media), where these issues are really pressing. But the wording is quite strange if that is the case.
-
captures values such as transparency and student autonomy
Indeed. “Privacy” makes it sound like a single factor, hiding the complexity of the matter and the importance of learners’ agency.
-
Activities such as time spent on task and discussion board interactions are at the forefront of research.
Really? These aren’t uncontroversial, to say the least. For instance, discussion board interactions often call for careful, mixed-method work with an eye to preventing instructor effect and confirmation bias. “Time on task” is almost a codeword for distinctions between models of learning. Research in cognitive science gives very nuanced value to “time spent on task” while the Malcolm Gladwells of the world usurp some research results. A major insight behind Competency-Based Education is that it can allow for some variance in terms of “time on task”. So it’s kind of surprising that this summary puts those two things to the fore.
-
Research: Student data are used to conduct empirical studies designed primarily to advance knowledge in the field, though with the potential to influence institutional practices and interventions. Application: Student data are used to inform changes in institutional practices, programs, or policies, in order to improve student learning and support. Representation: Student data are used to report on the educational experiences and achievements of students to internal and external audiences, in ways that are more extensive and nuanced than the traditional transcript.
Ha! The Chronicle’s summary framed these categories somewhat differently. Interesting. To me, the “application” part is really about student retention. But maybe that’s a bit of a cynical reading, based on an over-emphasis in the Learning Analytics sphere towards teleological, linear, and insular models of learning. Then, the “representation” part sounds closer to UDL than to learner-driven microcredentials. Both approaches are really interesting and chances are that the report brings them together. Finally, the Chronicle made it sound as though the research implied here were less directed. The mention that it has “the potential to influence institutional practices and interventions” may be strategic, as applied research meant to influence “decision-makers” is more likely to sway them than the type of exploratory research we so badly need.

often private companies whose technologies power the systems universities use for predictive analytics and adaptive courseware
-
the use of data in scholarly research about student learning; the use of data in systems like the admissions process or predictive-analytics programs that colleges use to spot students who should be referred to an academic counselor; and the ways colleges should treat nontraditional transcript data, alternative credentials, and other forms of documentation about students’ activities, such as badges, that recognize them for nonacademic skills.
Useful breakdown. Research, predictive models, and recognition are quite distinct from one another and the approaches to data that they imply are quite different. In a way, the “personalized learning” model at the core of the second topic is close to the Big Data attitude (collect all the things and sense will come through eventually) with corresponding ethical problems. Through projects vary greatly, research has a much more solid base in both ethics and epistemology than the kind of Big Data approach used by technocentric outlets. The part about recognition, though, opens the most interesting door. Microcredentials and badges are a part of a broader picture. The data shared in those cases need not be so comprehensive and learners have a lot of agency in the matter. In fact, when then-Ashoka Charles Tsai interviewed Mozilla executive director Mark Surman about badges, the message was quite clear: badges are a way to rethink education as a learner-driven “create your own path” adventure. The contrast between the three models reveals a lot. From the abstract world of research, to the top-down models of Minority Report-style predictive educating, all the way to a form of heutagogy. Lots to chew on.

“We need much more honesty, about what data is being collected and about the inferences that they’re going to make about people. We need to be able to ask the university ‘What do you think you know about me?’”

-
The importance of models may need to be underscored in this age of “big data” and “data mining”. Data, no matter how big, can only tell you what happened in the past. Unless you’re a historian, you actually care about the future — what will happen, what could happen, what would happen if you did this or that. Exploring these questions will always require models. Let’s get over “big data” — it’s time for “big modeling”.
-
Readers are thus encouraged to examine and critique the model. If they disagree, they can modify it into a competing model with their own preferred assumptions, and use it to argue for their position. Model-driven material can be used as grounds for an informed debate about assumptions and tradeoffs. Modeling leads naturally from the particular to the general. Instead of seeing an individual proposal as “right or wrong”, “bad or good”, people can see it as one point in a large space of possibilities. By exploring the model, they come to understand the landscape of that space, and are in a position to invent better ideas for all the proposals to come. Model-driven material can serve as a kind of enhanced imagination.

The Gamma: Programming tools for data journalism
(b) languages for novices or end-users, [...] If we can provide our climate scientists and energy engineers with a civilized computing environment, I believe it will make a very significant difference.
But data journalists, and in fact, data activist, social scientist, and so on, could be a "different type of novice", one that is more critically and politically involved (in the broader sense of the "politic" word).
The wider dialogue on important matters that is mediated, backed up and understood by dealing data, (as climate change) requires more voices that the ones are involved today, and because they need to be reason and argument using data, we need to go beyond climate scientist or energy engeeners as the only ones who need a "civilized computing environment" to participate in the important complex and urgent matters of today world. Previously, these more critical voices (activists, journalists, scientists) have helped to make policy makers accountable and more sensible on other important and urgent issues.
In that sense my work with reproducible research in my Panama Papers as a prototype of a data continuum environment, or others, like Gamma, could serve as an exploration, invitation and early implementation of what is possible to enrich this data/computing enhanced dialogue.
-
I say this despite the fact that my own work has been in much the opposite direction as Julia. Julia inherits the textual interaction of classic Matlab, SciPy and other children of the teletype — source code and command lines.
The idea of a tradition technologies which are "children of teletype" is related to the comparison we do in the data week workshop/hackathon. In our case we talk about "unix fathers" versus "dynabook children" and bifurcation/recombination points of this technologies:
-
If efficiency incentives and tools have been effective for utilities, manufacturers, and designers, what about for end users? One concern I’ve always had is that most people have no idea where their energy goes, so any attempt to conserve is like optimizing a program without a profiler.
-
The catalyst for such a scale-up will necessarily be political. But even with political will, it can’t happen without technology that’s capable of scaling, and economically viable at scale. As technologists, that’s where we come in.
May be we come before, by enabling this conversation (as said previously). Political agenda is currently coopted by economical interests far away of a sustainable planet or common good. Feedback loops can be a place to insert counter-hegemonic discourse to enable a more plural and rational dialogue between civil society and goverment, beyond short term economic current interest/incumbents.
-
This is aimed at people in the tech industry, and is more about what you can do with your career than at a hackathon. I’m not going to discuss policy and regulation, although they’re no less important than technological innovation. A good way to think about it, via Saul Griffith, is that it’s the role of technologists to create options for policy-makers.
Nice to see this conversation happening between technology and broader socio-political problems so explicit in Bret's discourse.
What we're doing in fact is enabling this conversation between technologist and policy-makers first, and we're highlighting it via hackathon/workshops, but not reducing it only to what happens there (an interesting critique to the techno-solutionism hackathon is here), using the feedback loops in social networks, but with an intention of mobilizing a setup that goes beyond. One example is our twitter data selfies (picture/link below). The necesity of addressing urgent problem that involve techno-socio-political complex entanglements is more felt in the Global South.

DATA GOVERNANCE
la Data Governance fa pensare ad una Pubblica Amministrazione come unico organismo pensante e decisorio. Un concetto facile da metabolizzare, ma che non rispecchia spesso l'architettura reale delle PA di grandi dimensioni come i Comuni capoluogo, ad esempio.
La Data Governance parte da una PA che ha progettato o implementato la sua piattaforma informatica di 1) gestione dei flussi di lavoro interni e 2) gestione di servizi erogati all'utenza, in maniera tale da eliminare totalmente l'uso del supporto cartaceo e da permettere esclusivamente il data entry sia internamente dagli uffici che dall'utenza che richiede servizi pubblici agli enti pubblici. La Data Governance può essere adeguatamente ed efficacemente attuata solo se nella PA si tiene conto di questi elementi anzidetti. In merito colgo l'occasione per citare le 7 piattaforme ICT che le 14 grandi città metropolitane italiane devono realizzare nel contesto del PON METRO. Ecco questa si presenta come un occasione per le 14 grandi città italiane di dotarsi della stessa DATA GOVERNANCE, visto che le 7 piattaforme ICT devono (requisito) essere interoperabili tra loro. La Data Governance si crea insieme alla progettazione delle piattaforme informatiche che permettono alla PA di "funzionare" nei territori. La Data Governance è indissolubilmente legata al "data entry". Il data entry non prevede scansioni di carta o gestione di formati di lavoro non aperti. La Data Governance nelle sue procedure operative quotidiana è alla base della politica open data di qualità. Una Data Governance della PA nel 2016-17-... non può ancora fondarsi nella costruzione manuale del formato CSV e relativa pubblicazione manuale ad opera del dipendente pubblico. Una Data Governance dovrebbe tenere in considerazione che le procedure di pubblicazione dei dataset devono essere automatiche e derivanti dalle funzionalità degli stessi applicativi gestionali (piattaforme ICT) in uso nella PA, senza alcun intervento umano se non nella fase di filtraggio/oscuramento dei dati che afferiscono alla privacy degli individui.

Borgman on terms used by the humanities and social sciences to describe data and other types of analysis
humanist and social scientists frequently distinguish between primary and secondary information based on the degree of analysis. Yet this ordering sometimes conflates data, sources, and resources, as exemplified by a report that distinguishes "primary resources, E. G., Books close quotation from quotation secondary resources, eat. Gee., Catalogs close quotation . Resources also categorized as primary or sensor data, numerical data, and field notebooks, all of which would be considered data in the sciences. Rarely would books, conference proceedings, and feces that the report categorizes as primary resources be considered data, except when used for text-or data-mining purposes. Catalogs, subject indices, citation indexes, search engines, and web portals were classified as secondary resources. These are typically viewed as tertiary resources in the library community because they describe primary and secondary resources. The distinctions between data, sources, and resources very by discipline and circumstance. For the purposes of this book, primary resources are data, secondary resources are reports of research, whether publications or intern forms, and tertiary resources are catalogs, indexes, and directories that provide access to primary and secondary resources. Sources are the origins of these resources.

Borgman notes that no social framework exist for data that is comparable to this framework that exist for analysis. CF. Kitchen 2014 who argues that pre-big data, we privileged analysis over data to the point that we threw away the data after words . This is what creates the holes in our archives.
He wonders capabilities [of the data management] must be compared to the remarkably stable scholarly communication system in which they exist. The reward system continues to be based on publishing journal articles, books, and conference papers. Peer-reviewed legitimizes scholarly work. Competition and cooperation are carefully balanced. The means by which scholarly publishing occurs is an unstable state, but the basic functions remained relatively unchanged. while capturing and managing the "data deluge" is a major driver of the scholarly infrastructure developments, no Showshow same framework for data exist that is comparable to that for publishing.

Humanistic research takes place in a rich milieu that incorporates the cultural context of artifacts. Electronic text and models change the nature of scholarship in subtle and important ways, which have been discussed at great length since the humanities first began to contemplate the scholarly application of computing.
-
Page 217
Methods for organizing information in the humanities follow from their research practices. Humanists fo not rely on subject indexing to locate material to the extent that the social sciences or sciences do. They are more likely to be searching for new interpretations that are not easily described in advance; the journey through texts, libraries, and archives often is the research.
-
Page 223
Borgman is discussing here the difference in the way humanists handle data in comparison to the way that scientists and social scientist:
When generating their own data such as interviews or observations, human efforts to describe and represent data are comparable to that of scholars and other disciplines. Often humanists are working with materials already described by the originator or holder of the records, such as libraries, archives, government agencies, or other entities. Whether or not the desired content already is described as data, scholars need to explain its evidentiary value in your own words. That report often becomes part of the final product. While scholarly publications in all fields set data within a context, the context and interpretation are scholarship in the humanities.
-
Pages 220-221
Digital Humanities projects result in two general types of products. Digital libraries arise from scholarly collaborations and the initiatives of cultural heritage institutions to digitize their sources. These collections are popular for research and education. … The other general category of digital humanities products consist of assemblages of digitized cultural objects with associated analyses and interpretations. These are the equivalent of digital books in that they present an integrated research story, but they are much more, as they often include interactive components and direct links to the original sources on which the scholarship is based. … Projects that integrate digital records for widely scattered objects are a mix of a digital library and an assemblage.
-
Page 219
In the humanities, it is difficult to separate artifacts from practices or publications from data.
-
Page 219
Humanities scholars integrate and aggregate data from many sources. They need tools and services to analyze digital data, as others do the sciences and social sciences, but also tools that assist them interpretation and contemplation.
-
Page 215
What seems a clear line between publications and data in the sciences and social sciences is a decidedly fuzzy one in the humanities. Publications and other documents are central sources of data to humanists. … Data sources for the humanities are innumerable. Almost any document, physical artifact, or record of human activity can be used to study culture. Humanities scholars value new approaches, and recognizing something as a source of data (e.g., high school yearbooks, cookbooks, or wear patterns in the floor of public places) can be an act of scholarship. Discovering heretofore unknown treasures buried in the world's archives is particularly newsworthy. … It is impossible to inventory, much less digitize, all the data that might be useful scholarship communities. Also distinctive about humanities data is their dispersion and separation from context. Cultural artifacts are bought and sold, looted in wars, and relocated to museums and private collections. International agreements on the repatriation of cultural objects now prevent many items from being exported, but items that were exported decades or centuries ago are unlikely to return to their original site. … Digitizing cultural records and artifacts make them more malleable and mutable, which creates interesting possibilities for analyzing, contextualizing, and recombining objects. Yet digitizing objects separates them from the origins, exacerbating humanists’ problems in maintaining the context. Removing text from its physical embodiment in a fixed object may delete features that are important to researchers, such as line and page breaks, fonts, illustrations, choices of paper, bindings, and marginalia. Scholars frequently would like to compare such features in multiple additions or copies.

Page 214
Borgman on information artifacts and communities:
Artifacts in the humanities differ from those of the sciences and social sciences in several respects. Humanist use the largest array of information sources, and as a consequence, the station between documents and data is the least clear. They also have a greater number of audiences for the data and the products of the research. Whereas scientific findings usually must be translated for a general audience, humanities findings often are directly accessible and of immediate interest to the general public.
-
Page 204
Borgman on the different types of data in the social sciences:
Data in the social sciences fall into two general categories. The first is data collected by researchers through experiments, interviews, surveys, observations, or similar names, analogous to scientific methods. … the second category is data collected by other people or institutions, usually for purposes other than research.
-
Page 202
Borgman on information artifacts in the social sciences
like the sciences, the social sciences create and use minimal information. Yet they differ in the sources of the data. While almost all scientific data are created by for scientific purposes, a significant portion of social scientific data consists of records credit for other purposes, by other parties.

Borgman on the challenges facing the humanities in the age of Big Data:
Text and data mining offer similar Grand challenges in the humanities and social sciences. Gregory crane provide some answers to the question what do you do with a million books? Two obvious answers include the extraction of information about people, places, and events, and machine translation between languages. As digital libraries of books grow through scanning avert such as Google print, the open content Alliance, million books project, and comparable projects in Europe and China, and as more books are published in digital form technical advances in data description, and now it says, and verification are essential. These large collections differ from earlier, smaller after it's on several Dimensions. They are much larger in scale, the content is more heterogenous in topic and language, the granularity creases when individual words can be tagged and they were noisy then there well curated predecessors, and their audiences more diverse, reaching the general public in addition to the scholarly community. Computer scientists are working jointly with humanist, language, and other demands specialist to pars tax, extract named entities in places, I meant optical character recognition techniques counter and Advance the state of art of information retrieval.

-
Page 122
Here Borgman suggest that there is some confusion or lack of overlap between the words that humanist and social scientists use in distinguishing types of information from the language used to describe data.
Humanist and social scientists frequently distinguish between primary and secondary information based on the degree of analysis. Yet this ordering sometimes conflates data sources, and resorces, as exemplified by a report that distinguishes quote primary resources, ed books quote from quote secondary resources, Ed catalogs quote. Resorts is also categorized as primary wear sensor data AMA numerical data and filled notebooks, all of which would be considered data in The Sciences. But rarely would book cover conference proceedings, and he sees that the report categorizes as primary resources be considered data, except when used for text or data mining purposes. Catalogs, subject indices, citation index is, search engines, and web portals were classified as secondary resources.
-
Pages 119 and 120
Here Borgman discusses the various definitions of data showing them working across the fields
the following definition of data is widely accepted in this context: AT&T portable representation of information in a formalized manner suitable for communication, interpretation, or processing. Examples of data include a sequence of bits, a table of numbers, the characters on a page, recording of sounds made by a person speaking Ori moon rocks specimen. Definitions of data often arise from Individual disciplines, but can apply to data used in science, technology, the social sciences, and the humanities: data are facts, numbers, letters, and symbols that describe an object, idea, condition, situation, or other factors.... Terms data and facts are treated interchangeably, as is the case in legal context. Sources of data includes observations, complications, experiment, and record-keeping. Observational data include weather measurements... And attitude surveys... Or involve multiple places and times. Computational data result from executing a computer model or simulation.... experimental data include results from laboratory studies such as measurements of chemical reactions or from field experiments such as controlled Behavioral Studies.... records of government, business, and public and private life also yield useful data for scientific, social scientific, and humanistic research.
-
Pages 117 to 1:19
Here Borgman discusses the ability to go back and forth between data and reports on data she cites Phil born 2005 on this for a while medicine. She also discusses how in the pre-digital error data was understood as a support mechanism for final publication and as a result was allowed to deteriorate or be destroyed after the Publications upon which they were based appeared.
-
Page 115
Borgman makes the point here that while there is a Commons in the infrastructure of scholarly publishing there is less of a Commons in the infrastructure 4 data across disciplines.
The infrastructure of scholarly publishing Bridges disciplines: every field produces Journal articles, conference papers, and books albeit in differing ratios. Libraries select, collect organize and make accessible publications of all types, from all fields. No comparable infrastructure exists for data. A few Fields have major mechanisms for publishing data in repositories. Some fields are in the stage of developing standards and practices to activate their data resorces and Nathan were widely accessible. In most Fields, especially Outside The Sciences, data practices remain local idiosyncratic, and oriented to current usage rather than preservation operation, and access. Most data collections Dash where they exist Dash are managed by individual agencies within disciplines, rather than by libraries are archives. Data managers usually are trained within the disciplines they serve. Only a few degree programs and information studies include courses on data management. The lack of infrastructure for data amplifies the discontinuities in scholarly publishing despite common concerns, independent debates continue about access to Publications and data.
-
Page 41
discussions of digital scholarship tend to distinguish implicitly or explicitly between data and documents. Some of you data and documents as a Continuum rather than a dichotomy in this sense data such as numbers images and observations are the initial products of research, and Publications are the final products that set research findings in context.
-
A great paragraph here on the value of interconnection
scholarly data and documents are of most value when they are interconnected rather than independent. The outcomes of a research project could be understood most fully if it were possible to trace an important finding from a grant proposal, to data collection, to a data set, to its publication, to its subsequent review and comment period journal articles are more valuable if one can jump directly from the article to those insights into later articles that cite the source article. Articles are even more valuable if they provide links to data on which they are based. Some of these capabilities already are available, but their expansion depends more on the consistency of the data description, access arrangements, and intellectual property agreement then on technological advances.
I think here of the line from Jim Gill may all your problems be technical
-
p. 8-actually this is link to p. 7, since 8 is excluded
Another trend is the blurring of the distinction between primary sources, generally viewed as unprocessed or unanalysed data, and secondary sources that set data in context.
Good point about how this is a new thing. On the next page she discusses how we are now collpasing the traditional distinction between primary and secondary sources.
-
Retrieval methods designed for small databases decline rapidly in effectiveness as collections grow...
This is an interesting point that is missed in the Distant reading controversies: its all very well to say that you prefer close reading, but close reading doesn't scale--or rather the methodologies used to decide what to close read were developed when big data didn't exist. How to you combine that when you can read everything. I.e. You close read Dickins because he's what survived the 19th C as being worth reading. But now, if we could recover everything from the 19th C how do you justify methodologically not looking more widely?

Rockwell and Sinclair note that corporations are mining text including our email; as they say here:
more and more of our private textual correspondence is available for large-scale analysis and interpretation. We need to learn more about these methods to be able to think through the ethical, social, and political consequences. The humanities have traditions of engaging with issues of literacy, and big data should be not an exception. How to analyze interpret, and exploit big data are big problems for the humanities.

Initially, the digital humanities consisted of the curation and analysis of data that were born digital, and the digitisation and archiving projects that sought to render analogue texts and material objects into digital forms that could be organised and searched and be subjects to basic forms of overarching, automated or guided analysis, such as summary visualisations of content or connections between documents, people or places. Subsequently, its advocates have argued that the field has evolved to provide more sophisticated tools for handling, searching, linking, sharing and analysing data that seek to complement and augment existing humanities methods, and facilitate traditional forms of interpretation and theory building, rather than replacing traditional methods or providing an empiricist or positivistic approach to humanities scholarship.
summary of history of digital humanities
-
Data are not useful in and of themselves. They only have utility if meaning and value can be extracted from them. In other words, it is what is done with data that is important, not simply that they are generated. The whole of science is based on realising meaning and value from data. Making sense of scaled small data and big data poses new challenges. In the case of scaled small data, the challenge is linking together varied datasets to gain new insights and opening up the data to new analytical approaches being used in big data. With respect to big data, the challenge is coping with its abundance and exhaustivity (including sizeable amounts of data with low utility and value), timeliness and dynamism, messiness and uncertainty, high relationality, semi-structured or unstructured nature, and the fact that much of big data is generated with no specific question in mind or is a by-product of another activity. Indeed, until recently, data analysis techniques have primarily been designed to extract insights from scarce, static, clean and poorly relational datasets, scientifically sampled and adhering to strict assumptions (such as independence, stationarity, and normality), and generated and alanysed with a specific question in mind.
Good discussion of the different approaches allowed/required by small v. big data.

dynamic documents
A group of experts got together last year at Daghstuhl and wrote a white paper about this.
Basically the idea is that the data, the code, the protocol/analysis/method, and the narrative should all exist as equal objects on the appropriate platform. Code in a code repository like Github, Data in a data repo that understands data formats, like Mendeley Data (my company) and Figshare, protocols somewhere like protocols.io and the narrative which ties it all together still at the publisher. Discussion and review can take the form of comments, or even better, annotations just like I'm doing now.

What type of team do you need to create these visualisations? OpenDataCity has a special team of really high-level nerds. Experts on hardware, servers, software development, web design, user experience and so on. I contribute the more mathematical view on the data. But usually a project is done by just one person, who is chief and developer, and the others help him or her. So, it's not like a group project. Usually, it's a single person and a lot of help. That makes it definitely faster, than having a big team and a lot of meetings.
This strengths the idea that data visualization is a field where a personal approach is still viable, as is shown also by a lot of individuals that are highly valuated as data visualizers.

After graduating from MIT at the age of 29, Loveman began teaching at Harvard Business School, where he was a professor for nine years.[8][10] While at Harvard, Loveman taught Service Management and developed an interest in the service industry and customer service.[8][10] He also launched a side career as a speaker and consultant after a 1994 paper he co-authored, titled "Putting the Service-Profit Chain to Work", attracted the attention of companies including Disney, McDonald's and American Airlines. The paper focused on the relationship between company profits and customer loyalty, and the importance of rewarding employees who interact with customers.[7][8] In 1997, Loveman sent a letter to Phil Satre, the then-chief executive officer of Harrah's Entertainment, in which he offered advice for growing the company.[7] Loveman, who had done some consulting work for the company in 1991,[11] again began to consult for Harrah's and, in 1998, was offered the position of chief operating officer.[8] He initially took a two year sabbatical from Harvard to take on the role of COO of Harrah's,[10] at the end of which Loveman decided to remain with the company.[12]

Great Principles of Computing<br> Peter J. Denning, Craig H. Martell
This is a book about the whole of computing—its algorithms, architectures, and designs.
Denning and Martell divide the great principles of computing into six categories: communication, computation, coordination, recollection, evaluation, and design.
"Programmers have the largest impact when they are designers; otherwise, they are just coders for someone else's design."

preferably
Delete "preferably". Limiting the scope of text mining to exclude societal and commercial purposes limits the usefulness to enterprises (especially SMEs that cannot mine on their own) as well as to society. These limitations have ramifications in terms of limiting the research questions that researchers can and will pursue.

Encourage researchers not to transfer the copyright on their research outputs before publication.
This statement is more generally applicable than just to TDM. Besides, "Encourage" is too weak a word here, and from a societal perspective, it would be far better if researchers were to retain their copyright (where it applies), but make their copyrightable works available under open licenses that allow publishers to publish the works, and others to use and reuse it.

In December 2014, FitBit released a pledge stating that it “is deeply committed to protecting the security of your data.” Still, we may soon be obliged to turn over the sort of information the device is designed to collect in order to obtain medical coverage or life insurance. Some companies currently offer incentives like discounted premiums to members who volunteer information from their activity trackers. Many health and fitness industry experts say it is only a matter of time before all insurance providers start requiring this information.

To date 5'-cytosine methylation (5mC) has not been reported in Caenorhabditis elegans, and using ultra-performance liquid chromatography/tandem mass spectrometry (UPLC-MS/MS) the existence of DNA methylation in T. spiralis was detected, making it the first 5mC reported in any species of nematode.
As a novel and potentially controversial finding, the huge amounts of supporting data are depositedhere to assist others to follow on and reproduce the results. This won the BMC Open Data Prize, as the judges were impressed by the numerous extra steps taken by the authors in optimizing the openness and easy accessibility of this data, and were keen to emphasize that the value of open data for such breakthrough science lies not only in providing a resource, but also in conferring transparency to unexpected conclusions that others will naturally wish to challenge.

The journal will accommodate data but should be presented in the context of a paper. The Winnower should not act as a forum for publishing data sets alone. It is our feeling that data in absence of theory is hard to interpret and thus may cause undue noise to the site.
This will be the case also for the data visualizations showed here, once the data is curated and verified properly. Still data visualizations can start a global conversation without having the full paper translated to English.

50 Years of Data Science, David Donoho<br> 2015, 41 pages
This paper reviews some ingredients of the current "Data Science moment", including recent commentary about data science in the popular media, and about how/whether Data Science is really di fferent from Statistics.
The now-contemplated fi eld of Data Science amounts to a superset of the fi elds of statistics and machine learning which adds some technology for 'scaling up' to 'big data'.

The explosion of data-intensive research is challenging publishers to create new solutions to link publications to research data (and vice versa), to facilitate data mining and to manage the dataset as a potential unit of publication. Change continues to be rapid, with new leadership and coordination from the Research Data Alliance (launched 2013): most research funders have introduced or tightened policies requiring deposit and sharing of data; data repositories have grown in number and type (including repositories for “orphan” data); and DataCite was launched to help make research data cited, visible and accessible. Meanwhile publishers have responded by working closely with many of the community-led projects; by developing data deposit and sharing policies for journals, and introducing data citation policies; by linking or incorporating data; by launching some pioneering data journals and services; by the development of data discovery services such as Thomson Reuters’ Data Citation Index (page 138).

It doesn’t work if we think the people who disagree with us are all motivated by malice, or that our political opponents are unpatriotic. Democracy grinds to a halt without a willingness to compromise; or when even basic facts are contested, and we listen only to those who agree with us.
C'mon, civic technologists, government innovators, open data advocates: this can be a call to arms. Isn't the point of "open government" to bring people together to engage with their leaders, provide the facts, and allow more informed, engaged debate?

paradox of unanimity - Unanimous or nearly unanimous agreement doesn't always indicate the correct answer. If agreement is unlikely, it indicates a problem with the system.
Witnesses who only saw a suspect for a moment are not likely to be able to pick them out of a lineup accurately. If several witnesses all pick the same suspect, you should be suspicious that bias is at work. Perhaps these witnesses were cherry-picked, or they were somehow encouraged to choose a particular suspect.

Set Semantics¶ This tool is used to set semantics in EPUB files. Semantics are simply, links in the OPF file that identify certain locations in the book as having special meaning. You can use them to identify the foreword, dedication, cover, table of contents, etc. Simply choose the type of semantic information you want to specify and then select the location in the book the link should point to. This tool can be accessed via Tools->Set semantics.
Though it’s described in such a simple way, there might be hidden power in adding these tags, especially when we bring eBooks to the Semantic Web. Though books are the prime example of a “Web of Documents”, they can also contribute to the “Web of Data”, if we enable them. It might take long, but it could happen.

Useful examples. Could imagine something like Wikity, FedWiki, or other forms of content federation to work through this in a much-needed upgrade from the “Personal Home Pages” of the early Web. Do see some connections to Sandstorm and the new WordPress interface (which, despite being targeted at WordPress.com users, also works on self-hosted WordPress installs). Some of it could also be about the longstanding dream of “keeping our content” in social media. Yes, as in the reverse from Facebook. Multiple solutions exist to do exports and backups. But it can be so much more than that and it’s so much more important in educational contexts.

The EDUPUB Initiative VitalSource regularly collaborates with independent consultants and industry experts including the National Federation of the Blind (NFB), American Foundation for the Blind (AFB), Tech For All, JISC, Alternative Media Access Center (AMAC), and others. With the help of these experts, VitalSource strives to ensure its platform conforms to applicable accessibility standards including Section 508 of the Rehabilitation Act and the Accessibility Guidelines established by the Worldwide Web Consortium known as WCAG 2.0. The state of the platform's conformance with Section 508 at any point in time is made available through publication of Voluntary Product Accessibility Templates (VPATs). VitalSource continues to support industry standards for accessibility by conducting conformance testing on all Bookshelf platforms – offline on Windows and Macs; online on Windows and Macs using standard browsers (e.g., Internet Explorer, Mozilla Firefox, Safari); and on mobile devices for iOS and Android. All Bookshelf platforms are evaluated using industry-leading screen reading programs available for the platform including JAWS and NVDA for Windows, VoiceOver for Mac and iOS, and TalkBack for Android. To ensure a comprehensive reading experience, all Bookshelf platforms have been evaluated using EPUB® and enhanced PDF books.

Data gathering is ubiquitous in science. Giant databases are currently being minedfor unknown patterns, but in fact there are many (many) known patterns that simplyhave not been catalogued. Consider the well-known case of medical records. A patient’smedical history is often known by various individual doctor-offices but quite inadequatelyshared between them. Sharing medical records often means faxing a hand-written noteor a filled-in house-created form between offices.

Among the most useful summaries I have found for Linked Data, generally, and in relationship to libraries, specifically. After first reading it, got to hear of the acronym LODLAM: “Linked Open Data for Libraries, Archives, and Museums”. Been finding uses for this tag, in no small part because it gets people to think about the connections between diverse knowledge-focused institutions, places where knowledge is constructed. Somewhat surprised academia, universities, colleges, institutes, or educational organisations like schools aren’t explicitly tied to those others. In fact, it’s quite remarkable that education tends to drive much development in #OpenData, as opposed to municipal or federal governments, for instance. But it’s still very interesting to think about Libraries and Museums as moving from a focus on (a Web of) documents to a focus on (a Web of) data.

The effectiveness of infographics, or any other form of communication, can be measured in terms of whether people:
- pay attention to it
- understand it
- remember it later
Titles are important. Ideally, the title should concisely state the main point you want people to grasp.
Recall of both labels and data can be improved by using redundancy -- text as well as images. For example:
- flags in addition to country names
- proportional bubbles in addition to numbers.

In a nutshell, an ontology answers the question, “What things can we say exist in a domain, and how do we describe those things that relate to each other?”

According to inventor of the World Wide Web, Tim Berners-Lee, there are four key principles of Linked Data (Berners-Lee, 2006): Use URIs to denote things. Use HTTP URIs so that these things can be referred to and looked up (dereferenced) by people and user agents. Provide useful information about the thing when its URI is dereferenced, leveraging standards such as RDF, SPARQL. Include links to other related things (using their URIs) when publishing data on the web.

Access to primary data from trials has important implications for both clinical practice and research, including that published conclusions about efficacy and safety should not be read as authoritative. The reanalysis of Study 329 illustrates the necessity of making primary trial data and protocols available to increase the rigour of the evidence base.
How can anyone argue that science isn't served by making primary data available? We must recognize that more people are harmed by not sharing data than are harmed by data being shared.

Because cue-evoked DA release developed throughout learning, we examined whether DA release correlated with conditioned-approach behavior. Figure 1E and table S1 show that the ratio of the CS-related DA release to the reward-related DA release was significantly (r2 = 0.68; P = 0.0005) correlated with number of CS nosepokes in a conditioning session (also see fig. S4).

This approach is called change data capture, which I wrote about recently (and implemented on PostgreSQL). As long as you’re only writing to a single database (not doing dual writes), and getting the log of writes from the database (in the order in which they were committed to the DB), then this approach works just as well as making your writes to the log directly.
Interesting section on applying log-orientated approaches to existing systems.

I feel that there is a great benefit to fixing this question at the spec level. Otherwise, what happens? I read a web page, I like it and I am going to annotate it as being a great one -- but first I have to find out whether the URI my browser is used, conceptually by the author of the page, to represent some abstract idea?

Among articles with invisible datasets, we found an average of 2.9 to 3.4 datasets, suggesting there were approximately 200,000 to 235,000 invisible datasets generated from NIH-funded research published in 2011.

The comparison between the model and the experts is based on the species distribution models (SMDs), not on actual species occurrences, so the observed difference could be due to weakness in the SDM predictions rather than the model outperforming the experts. The explanation for this choice in Footnote 4 is reasonable, but I wonder if it could be addressed by rarifying the sampling appropriately.

Anyone withholding the methods and results of a clinical trial is already in breach of multiple codes and regulations, including the Declaration of Helsinki, various promises from industry and professional bodies, and, in many cases, the United States Food and Drug Administration (FDA) Amendment Act of 2007. Indeed, a recently published cohort study of trials in clinicaltrials.gov found that more than half had failed to post results; and even though the FDA is entitled to issue fines of $10,000 a day for transgressions, no such fines have ever been levied [3].
Sticks don't work if they aren't used. I find this rather disturbing.

The big question, of course, is whether that player has to be a private capitalist corporation, or some federated, publicly-run set of services that could reach a data-sharing agreement free of monitoring by intelligence agencies.
So there we are. It is pretty straight forward really.

But if you turn data into a money-printing machine for citizens, whereby we all become entrepreneurs, that will extend the financialization of everyday life to the most extreme level, driving people to obsess about monetizing their thoughts, emotions, facts, ideas—because they know that, if these can only be articulated, perhaps they will find a buyer on the open market. This would produce a human landscape worse even than the current neoliberal subjectivity. I think there are only three options. We can keep these things as they are, with Google and Facebook centralizing everything and collecting all the data, on the grounds that they have the best algorithms and generate the best predictions, and so on. We can change the status of data to let citizens own and sell them. Or citizens can own their own data but not sell them, to enable a more communal planning of their lives. That’s the option I prefer.
Very well thought out. Obviously must know about read write web, TSL certificate issues etc. But what does neoliberal subjectivity mean? An interesting phrase.

Mike Olson of Cloudera is on record as predicting that Spark will be the replacement for Hadoop MapReduce. Just about everybody seems to agree, except perhaps for Hortonworks folks betting on the more limited and less mature Tez. Spark’s biggest technical advantages as a general data processing engine are probably: The Directed Acyclic Graph processing model. (Any serious MapReduce-replacement contender will probably echo that aspect.) A rich set of programming primitives in connection with that model. Support also for highly-iterative processing, of the kind found in machine learning. Flexible in-memory data structures, namely the RDDs (Resilient Distributed Datasets). A clever approach to fault-tolerance.
Spark's advantages:
- DAG processing model
- programming primitives for DAG model
- highly-iterative processing suited for ML
- RDD in-memory data structures
- clever approach to fault-tolerance
