    1. By ignoring the diversity and discord of the ‘goals’ of theparticipants involved, the differentiation of strategies, and the incongruence of theconceptual frames of reference within a cooperating ensemble, much of the currentCSCW research evades the problem of how to provide computer support for peoplecooperating through the establishment of a common information space.

      Has this design challege been adequately addressed in CSCW (and CHI, for that matter) in the last 30-ish years?

    2. On the one hand, the visibility requirement is amplified by this divergence. Thatis, knowledge of the identity of the originator and the situational context motivat-ing the production and dissemination of the information is required so as to enableany user of the information to interpret the likely motives of the originator. On theother hand, however, the visibility requirement is moderated by the divergence ofinterests and motives. A certain degree of opaqueness is required for discretionarydecision making to be conducted in an environment charged with colliding inter-ests. Hence,visibility must be bounded.

      What role does system meta data (version control, user history, etc.) play in bounding the visibility of decision making?

      This also seems to be an area ripe for more collaborative design approaches (participatory, reflective, feminist, etc.)

    3. Thus, a computer-basedsystem supporting cooperative work involving decision making should enhancethe ability of cooperating workers to interrelate their partial and parochial domainknowledge and facilitate the expression and communication of alternative perspec-tives on a given problem. This requires a representation of the problem domainas a whole as well as a representation, in some form, of the mappings betweenperspectives on that problem domain.

      This seems to still be a major challenge in information system design as well as collaborative workflow. Even if the information/meta context is made available, do people use it?

    1. Theproblem, then, was centered by social scientists in the process of design. Cer-tainly, many studies in CSCW, HCI, information technology, and informa-tion science at least indirectly have emphasized a dichotomy betweendesigners, programmers, and implementers on one hand and the social ana-lyst on the other.

      Two different camps on how to resolve this problem:

      1) Change more flexible social activity/protocols to better align with technical limitations 2) Make systems more adaptable to ambiguity

    2. In particular, concurrency control problems arise when the software, data,and interface are distributed over several computers. Time delays when ex-changing potentially conflicting actions are especially worrisome. ... Ifconcurrency control is not established, people may invoke conflicting ac-tions. As a result, the group may become confused because displays are incon-sistent, and the groupware document corrupted due to events being handledout of order. (p. 207)

      This passage helps to explain the emphasis in CSCW papers on time/duration as a system design concern for workflow coordination (milliseconds between MTurk hits) versus time/representation considerations for system design

    1. CONCLUSIONS: These findings suggest that higher standing BP is a biomarker that helps identify persons with combat PTSD who are likely to benefit from prazosin. These results also are consistent with α1AR activation contributing to PTSD pathophysiology in a subgroup of patients.

      This is precisely the results I would expect. However, I completely disagree with their interpretation.

      People with high blood pressure (BP) can tolerate a reduction in BP without instigating compensatory mechanisms. People with normal or low BP would invoke compensation by the sympathetic nervous system in response to alpha blockade. This would counteract the depressant effects of adrenergic antagonism. Indeed, adrenaline and noradrenaline elevate in response to standing, which I find to be an obvious prediction. Thus, the lack of benefit from prazosin in these subjects may be mediated by an increase in adrenergic receptor activation other than the apha1-adrenoreceptor; in particular, the beta-adrenergic receptors are likely at fault. Propranolol, a beta-blocker, is used for PTSD, so this mechanism seems well substantiated.

      The study apparently found benefit for patients with BP over 110 (with more benefit for higher BP). Thus, I would conclude that systolic pressure below 110 induce compensation.

    1. At least as far as these gentlemen were concerned, this was a talk about the future of technology. Taking their cue from Elon Musk colonizing Mars, Peter Thiel reversing the aging process, or Sam Altman and Ray Kurzweil uploading their minds into supercomputers, they were preparing for a digital future that had a whole lot less to do with making the world a better place than it did with transcending the human condition altogether and insulating themselves from a very real and present danger of climate change, rising sea levels, mass migrations, global pandemics, nativist panic, and resource depletion. For them, the future of technology is really about just one thing: escape.

      So often we consider technology as being about particular things, but it can be much more fruitful when thinking of it as a system.

    1. Perelman says his Babel Generator also proves how easy it is to game the system. While students are not going to walk into a standardized test with a Babel Generator in their back pocket, he says, they will quickly learn they can fool the algorithm by using lots of big words, complex sentences, and some key phrases - that make some English teachers cringe. "For example, you will get a higher score just by [writing] "in conclusion,'" he says.

    1. an environment unlike anything they will encounter outside of school

      Hm? Aren’t they likely to encounter Content Management Systems, Enterprise Resource Planning, Customer Relationship Management, Intranets, etc.? Granted, these aren’t precisely the same think as LMS. But there’s quite a bit of continuity between Drupal, Oracle, Moodle, Sharepoint, and Salesforce.

    2. mandate the use of "learning management systems."

      Therein lies the rub. Mandated systems are a radically different thing from “systems which are available for use”. This quote from the aforelinked IHE piece is quite telling:

      “I want somebody to fight!” Crouch said. “These things are not cheap -- 300 grand or something like that? ... I want people to want it! When you’re trying to buy something, you want them to work at it!”

      In the end, it’s about “procurement”, which is quite different from “adoption” which is itself quite different from “appropriation”.

    3. institutional demands for enterprise services such as e-mail, student information systems, and the branded website become mission-critical

      In context, these other dimensions of “online presence” in Higher Education take a special meaning. Reminds me of WPcampus. One might have thought that it was about using WordPress to enhance learning. While there are some presentations on leveraging WP as a kind of “Learning Management System”, much of it is about Higher Education as a sector for webwork (-development, -design, etc.).

    1. (At the time, Stephen Downes mocked me for thinking that this was an important aspect of LMS design to consider.)

      An interesting case where Stephen’s tone might have drowned a useful discussion. FWIW, flexible roles and permissions are among the key things in my own personal “spec list” for a tool to use with learners, but it’s rarely possible to have that flexibility without also getting a very messy administration. This is actually one of the reasons people like WordPress.

    2. Do you know what the feature set was that had faculty from Albany to Anaheim falling to their knees, tears of joy streaming down their faces, and proclaiming with cracking, emotion-laden voices, "Finally, an LMS company that understands me!"?

      While this whole bit is over-the-top, à la @mfeldstein67, must admit that my initial reaction was close to that. For a very similar reason. Still haven’t had an opportunity to use Canvas with learners, but the overall workflow for this type of feature really does make a big difference. The openness aspect is very close to gravy. After all, there are ways to do a lot of work in the open without relying on any LMS. But the LMS does make a huge difference in terms of such features as quickly grading learners’ work.

    3. Why, they would build an LMS. They did build an LMS. Blackboard started as a system designed by a professor and a TA at Cornell University. Desire2Learn (a.k.a. Brightspace) was designed by a student at the University of Waterloo. Moodle was the project of a graduate student at Curtin University in Australia. Sakai was built by a consortium of universities. WebCT was started at the University of British Columbia. ANGEL at Indiana University.

    1. An institution has implemented a learning management system (LMS). The LMS contains a learning object repository (LOR) that in some aspects is populated by all users across the world  who use the same LMS.  Each user is able to align his/her learning objects to the academic standards appropriate to that jurisdiction. Using CASE 1.0, the LMS is able to present the same learning objects to users in other jurisdictions while displaying the academic standards alignment for the other jurisdictions (associations).

      Sounds like part of the problem Vitrine technologie-éducation has been tackling with Ceres, a Learning Object Repository with a Semantic core.

    1. Enhanced learning experience Graduate students now receive upgraded iPads, and all students access course materials with Canvas, a new learning management software. The School of Aeronautics is now the College of Aeronautics; and the College of Business and Management is hosting a business symposium Nov. 15.

      This from a university which had dropped Blackboard for iTunes U.

    1. It’s precisely to meet these demands that Cegid recently launched a Learning Management System (LMS) specifically dedicated to Healthcare, a sector that is converting more and more to cloud-based systems.

      Norman's Law of eLearning Tool Convergence

      Any eLearning tool, no matter how openly designed, will eventually become indistinguishable from a Learning Management System once a threshold of supported use-cases has been reached.

    1. Over the course of many years, every school has refined and perfected the connections LMSs have into a wide variety of other campus systems including authentication systems, identity management systems, student information systems, assessment-related learning tools, library systems, digital textbook systems, and other content repositories. APIs and standards have decreased the complexity of supporting these connections, and over time it has become easier and more common to connect LMSs to – in some cases – several dozen or more other systems. This level of integration gives LMSs much more utility than they have out of the box – and also more “stickiness” that causes them to become harder to move away from. For LMS alternatives, achieving this same level of connectedness, particularly considering how brittle these connections can sometimes become over time, is a very difficult thing to achieve.

    1. This has much in common with a customer relationship management system and facilitates the workflow around interventions as well as various visualisations.  It’s unclear how the at risk metric is calculated but a more sophisticated predictive analytics engine might help in this regard.

      Have yet to notice much discussion of the relationships between SIS (Student Information Systems), CRM (Customer Relationship Management), ERP (Enterprise Resource Planning), and LMS (Learning Management Systems).

    1. If you frequent the Overwatch sub-Reddit, or any forum that regularly discuses the game, you will have no doubt ran into many reports of players getting abused by others during matches, especially in Competitive Play.

      Finally game companies figured out reporting system to decrease cheating. However, some inevitable problems are still no ignorable. Although reporting system has made cheating detection more accurate and effective, there could also be some malicious reports that can have honest players be banned. So each solution has its advantages and disadvantages and both of them would be deadly.

    1. Mackenzie River
      The Mackenzie River is a major river system in northwestern North America. It is exceeded only in basin size by the Mississippi-Missouri system. The entire Mackenzie River system is 2,635 miles long and passes through many lakes before emptying into the Beaufort Sea of the Arctic Ocean. The Mackenzie River alone is 1,025 miles long when measured from Great Slave Lake. It begins at Great Slave Lake where the elevation is 512 feet above sea level. Great Slave Lake can be as deep as 2,000 feet in certain places. It is filled with clear water on the eastern side and shallow, murky water on the western side. The headwaters of the Mackenzie River include numerous large rivers. The drainage basins of the Mackenzie River include the Liard River, Peace River, and Athabasca River. The ice that forms on the Mackenzie River over the winter months begins the break up in early to mid-May in the southern sections. Ice covering some portions of the Mackenzie River can break up as late as the end of May. The Mackenzie River basin is home to a very small and sparse population despite the natural resources available in this area. This area is home to muskrat, marten, beaver, lynx, and fox. Pulpwood and other small conifer trees can be found here. Petroleum and natural gas are usually the underlying reason larger settlements have formed in this area (Robinson 1999).

    2. Alyeska oil pipeline
      The oil discovered in the Prudhoe Bay oil field in the North Slope region of Alaska in 1968 was the “largest oil field discovered in North America.” In 1969, a Trans-Alaska pipeline to transport oil from the North Slope was proposed by the Trans-Alaska Pipeline System. The Trans-Alaska Pipeline System was comprised of three major oil corporations. Despite many other ideas and suggestions to transport this oil, the oil industry reached a consensus in favor of the pipeline proposal of the Trans-Alaska Pipeline System (Busenberg, 2013). Construction of the Alyeska oil pipeline, also known as the Alaska pipeline or trans-Alaska pipeline, began in 1975. This pipeline was built by the Alyeska Pipeline Service Company, a group that was made up of seven different oil companies. In certain regions, the pipeline is buried underground, but where there is permafrost, the pipeline is constructed above the ground. The pipeline crosses over 800 river and streams and passes through three mountain ranges. The first oil was delivered from Prudhoe Bay to Valdez on June 20, 1977. This oil had to travel through the 789 mile long pipeline to reach its destination (Alaska Public Lands Information Centers, n.d.). See below for a link to “Pipeline! The story of the building of the trans-Alaska pipeline” video posted on YouTube by the Alaska National Parks service.

    1. Great Slave Lake

      The Great Slave Lake was found in 1771 by Samuel Hearne (Ernst). Many others passed through during the Klondike Gold Rush in 1896-1899, but the region surrounding the Great Slave Lake remained greatly unoccupied. In 1930, a radioactive uranium mineral called pitchblende, or uraninite, was discovered on the shore of the Great Slave Lake and incentivized colonizers. 1934, gold was discovered on Yellowknife Bay, which led to a Yellowknife community settlement. Today, additional communities in this region include Hay River, Fort Resolution, Fort Providence, and Behchoko. The Great Slave Lake is the fifth largest lake is North America and is part of the Mackenzie River System. The Lake gets its name from a tribe of Native Americans called Slavery First Nations (National Geographic). This tribe fished for sustenance and did not explore farther than their immediate surroundings. Their neighbors, the Cree, thought the tribe was weak and often called them awonak, which means slaves. Explorer Peter Pond named the lake the Slave Lake in 1785 and then the Great Slave Lake in 1790. The Lake is known for its variety of types of fish, including trout, pike, and Arctic grayling. The Great Slave Lake is covered in snow and ice 8 months out of the year. The Great Slave Lake region is also the home to the largest intact forest in the world, the Boreal Forest, which contains evergreens, bogs, shallow lakes, and ponds (Pala). This Great Slave Lake cove is the habitat for caribou, waterfowl, beavers, and many fish species.

    1. This leads to the second point I once made: that students no longer need to actually read the material to get impressive grades, which contributes to both student and administrator scorn for the affected disciplines. This point caused some push-back, since professors and fellow students noted that if I wasn’t reading the material, it was my own fault for not getting the full benefit of the course. I agreed, but countered that if the difference between my reading very little of the material instead of it all was a 10 to 15 percent bump in my final grade, what did that imply about the value of said material to the course? Srigley argues that less than 20 percent of his students even access the weekly readings for his courses, largely because they know they don’t have to ­– “they can get an 80 without ever opening a book.”

      Again, this implies that the professor should care. One of the principles behind my grading system is that I don't. People are welcome to do whatever they want and they get the same grade, unless they do exceptional work.

      This also implies that grades are somehow the currency of learning and that if you are getting good grades without learning, then you are somehow "winning."

      This is a misunderstanding of grades. They are really the bits of an expert system that converts qualitative evaluation of individual performances into a final score that helps people categories graduates. So they are secondary to the actual learning and performance.

    1. Now they recognize they are not essential

      In the late 1800s and early 1900s northern explorers depended on the indigenous people. The natives knew the land, the climate, and the wildlife. Because of their knowledge, the indigenous northerners served as local guides in this harsh and uninviting place. The native people also served as interpreters for researchers and were a lifeline for those that had little-to-no knowledge of how to survive in that kind of environment. However, they were not always seen as important figures. As southern technologies became more and more prominent in the far north, native peoples were pushed aside. “The airplane and helicopter strained relations among researchers and northerners. These technologies relieved field-workers from establishing extensive and regular relationships with locals as guides, interpreters, and informants. Permafrost scientists in particular could produce knowledge about the Arctic environment without Inuit expertise and apply that research in governmental construction projects without consulting locals” (108). The Inuits began to view the government scientists as pests, “they arrived in summer ‘in lusty swarm’ and were just as annoying” (108). Many researchers come during the warm months and gather information that allows them to cut ties to the indigenous people. The use of modern technology in the north forces Inuit to work menial jobs and completely change their way of life in order to survive in the modernizing landscape. While the industrial system has brought many valuable things to them, the Inuit are no longer needed or heard. If it is in the best interest of the oil industry, a pipeline would be built right over their homeland, even if they are still on it.

    1. Technologies & education system changing in recent times tutors should consider educating students with the latest technologies available. In the evolution of technology with apps, projector screens, Digital media, and last but not the least online learning platforms some fundamentals of teaching remains as it is, so if tutors can implement these basic ideas in his/her tutoring style with students can cope up with the evolution of digital education.

    2. According to the report of the UK Government, Department of Education (published on January 10, 2014), there were altogether 24372 public schools comprising of 16818 State-funded primary schools, 3268 State funded and 2420 other Secondary schools and 4476 independent schools. There are also 1039 special (state funded) and non-maintained schools. The same report says that there were 438000 teachers in state-funded schools in England on a full-time equivalent basis in 2012. The numbers at both ends have naturally increased at the time of writing this article. But the big question that is looming over the education system of England is whether, even after the best effort by the UK Government and the State schools, the public school system is successful in educating their children properly or not.

    1. The Swedish school system has wholeheartedly, and probably too quickly and eagerly, embraced this new agenda. Last fall, 200 teachers attended a major government-sponsored conference discussing how to avoid "traditional gender patterns" in schools. At Egalia, one model Stockholm preschool, everything from the decoration to the books and toys are carefully selected to promote a gender-equal perspective and to avoid traditional presentations of gender and parenting roles

    1. If you ain't talking about the teacher in the classroom, I ain't listening. Teacher quality matters. Too many in the profession are quick to awfulize students in poverty to rationalize poor results. Better teaching inspires students and gets better results. Better teaching engages students and keeps them in classrooms, rather than the streets. Better teaching is the one thing we never really talk about. Better teaching is the only mechanism we have left.

      What are some ways to significantly improve teaching in these communities? The teaching doesn't happen in a vacuum and we need a plan to counteract the systemic forces at work that maintain the status quo.

    1. systems analysis in this regard demands an ethnographic retooling,one in which ethnography might need to be conducted in government centers far from where theactual roads are constructed and might take into account politicians, technocrats, economists, en-gineers, and road builders, as well as road users themselves

      Understanding this paradigm, what does it mean to hold hearings and lectures. What does it say about the relocation of authority away from target location. Does this provide any insight on the dynamics of social and political justice/injustice within an economic nation?

    1. We do not want to leave the school system behind. We need to keep driving toward where we want everyone to be versus waiting until everyone is ready. The end goal will involve the Internet, and there needs to be a framework for it.

      But we do want to leave it behind--the words we use--"school system" tell us exactly what is at the center--schools. What we learn are learn systems where learning is at the center which implies tacit-wise that the learner is at the center.
