List of Predatory Publications - 3 views

  •  
    This list is not to be taken at face value (many of the publishers on it do have legitimate journals), but it serves as a reminder that there are many predatory journals that ask scholars to pay a lot of money to share their work, and many that also skirt traditional peer review processes in order to get money from unwary authors.

    while the list is not provided as an evidence based indicator of relative credibility, Beall's site and blog do give quite a bit of 'food for thought'. There are certainly a number of dodgy publications, and like many I have been bombarded by invitations to publish, act as a guest editor etc. If you dont work for an organisation willing to pay the cost for open access publishing, it is an expensive option for individuals. There needs to be a clearer means of determining relevance and credibility of material at times.

THE FUTURE OF THE BOOK - 11 views

  •  
    The year I graduated high school, the media was overrun with speculation about a new technology set to shake the foundation of the world. What was it? We weren't told, exactly. All we knew was that code name "IT" was so revolutionary that we would have to rebuild our cities from scratch.

    Thank you for sharing. I also heard that many universities are getting rid of their printed textbooks and only using e-texbook due to high prices that students have to pay for their printed textbooks. They may order in the printed textbook, but majority of schools are going digital.

    Thank you for sharing this resource. This reminds me of a news article I read before, which is "Apple Announces E-Book Store". According to that news article, Apple announced the create of iBook store in Apple's event in Jan 27 2010, hoping to reshape the e-book industry with a vast selection of electronic books in iBook. Electronic books offered in iBook store are around the same price as Amazon's Kindle platform, but with much more functions and convenience. Taking the form of iPad, and with the support of five largest publishers in the world, iBook offers the electronic version of various books and ebbeds multimedia such as photos, videos, and audio files into books, which is revolutionary. Therefore, the rapid development of technology has promoted the rapid changes and upgrading in book industry. From traditional physical books that we buy from retailers or borrow from libraries, to the online book sellers who sell both physical books and electronic books, to today, ebook stores in portable and mobile devices, how we read, when we read, where we read, and what we read have been transformed to a large extent.
  •  
    This is a good article. Sometimes, we think new technology will be a disrupted tech to kill and totally replace old industry.But actually, for old industry, the market will shrink a lot ,but won't totally disappear.
  •  
    What's going to happen with printed books?
  •  
    It depends on which side of the fence is one sitting on. The truth is the book is here to stay.
  •  
    It is interesting that whenever a new innovation is introduced, the current one is declared dead before its final time arrives. Books in whatever format are appealing to different audiences for various reasons. To think that the introduction of e-books was going to lead to a declaration of war on printed books is laughable. Books will be with us for as long as we are still in this world. Does format matter? only time will tell.
  •  
    Long back Lancaster wrote about paperless society but still we are heavily depending on paper only. Technology has fast evolved. First we talked about e-libraries then virtual libraries and now contemplating cloud based libraries. Many technologies have come and gone but paper is still ubiquitous.

What Does Your Brain Like Better: Paper or Ebooks? - 6 views

  •  
    This is an interesting post. Thank you for your sharing. As mentioned in this post, new research shows that electronic readers promoted more deep reading and less active learning. However, from my own experience, I feel like electronic reading leads to less deep reading but more active leaning. For me, I will never choose to read electronically if I have the physical version of the book because reading from digital devices, such as e-readers, tablets and smartphones, make me feel it's not like reading, it's more like looking through some online content or some one else blog posts. When read electronic books, it easy for me to skip around, and lose focus, attention or patience. I always need to read a second time for fully understanding a paragraph, when I read electronically. Also, with out the convenient of highlighting and making notes, reading electronic books prevent me from better understanding the content and thinking deeply. However, reading electronically, especially reading online might promote active learning because in some online reading website or softwares, there's interactive section on the side where readers of the book or article post their own opinions or form a discussion. This promote people to read, think and learn actively and collaboratively.

    For the topic of whether you like physical book or ebooks, we have discussed a lot during our class discussion. And the result is, all people prefer physical book other than ebook, the main reason that people said for their choices is the same one, the reading speed could be much faster when they are reading with ebook because they are scanning the texts in the device, however, by this way, they don't remember much about what they just read and have to read again and again in order to understand what the content is talking about. Reading with physical book make them feel more comfortable that they can take some notes in the margin of the book and they all like the texture of physical book.
  •  
    "electronic readers promoted more deep reading and less active learning" Some of my observations. I believe the future is for electronic reading only.
  •  
    For me, maybe I am old school, it depends on the mood. I am wired towards both the print and electronic books. I cannot wait to have a printed book in my hand this Christmas holiday. The smell of the new selection of books and the paging through is a wonderful experience.

    It's unquestionable that Research4Life has had a significant impact in improving access to research information for communities in developing countries. I do have a number of criticisms about how the program is organized and delivered, however. 1. Publisher participation in the program is 'entirely voluntary', without 'a single contract (being) signed between any of the partners' (Aaronson, 2004), meaning that publishers can opt out at any point. This issue was highlighted in 2011 when Elsevier, Lipincott Williams & Wilkins, Springer and the American Association for the Advancement of Science (AAAS, publisher of Science Magazine) withdrew access to over 2500 journals through the HINARI system. Following international attention, and widespread condemnation, publishers restored access, with Elsevier announcing that they were in discussions with the government in Bangladesh to transition towards a paid licensing scheme (Wise, 2011). 2. Countries that meet the eligibility criteria of the program (which are based on the World Bank's listing of Lower and Lower Middle Income Countries) are sometimes excluded. Take for example India or Pakistan- although these countries are in the lists of eligible countries, the publishers deliberately exclude participation to protect whatever business they may have in these countries. So although hundreds of institutions could benefit, they exclude access to protect the business they receive from a handful of institutions. 3. Access to content is delivered through a single username and password for each institution. This is problematic for librarians, as they are unable to ensure the security of the password (a well-meaning researcher may share the password with a colleague in another institution, violating the license agreement). Abuse of institutional accounts has severe consequences, and librarians are sent messages from Research4Life threatening to not only cut off the institution, but all institutions in their country if they

Open Education | OKFN:LOCAL India - 0 views

    A local group of the open knowledge foundation 1. Push for Open Science and Research practices in Indian research institutions. . 2. More involvement of citizens in the spirit of Open Knowledge Involvement of the masses in order to work towards making ourselves a better managed nation. Constitutional instruments like the Public Interest Litigation (PIL), the Right To Information (RTI), etc., lose their relevance without complete transparency in the dissemination of government as well as non-government data. Building a mass-based system of knowledge-banks can help us a lot in achieving our goal. We can assist the governments for making more information public, wherever necessary. 3. Push for education. Involving the masses can to a great extent result in a quicker transformation of the present scene (for example, we can have citizens making study material open and free and also involve them more in the dispersion of education). We aim to arrange for vocational profession-based education for the adult population.

The Baloney Detection Kit: Carl Sagan's Rules for Bullshit-Busting and Critical Thinking - 3 views

  •  
    "Just as important as learning these helpful tools, however, is unlearning and avoiding the most common pitfalls of common sense. Reminding us of where society is most vulnerable to those, Sagan writes: In addition to teaching us what to do when evaluating a claim to knowledge, any good baloney detection kit must also teach us what not to do. It helps us recognize the most common and perilous fallacies of logic and rhetoric. Many good examples can be found in religion and politics, because their practitioners are so often obliged to justify two contradictory propositions.He admonishes against the twenty most common and perilous ones - many rooted in our chronic discomfort with ambiguity - with examples of each in action"
  •  
    The 20 fallacies: "ad hominem - Latin for "to the man," attacking the arguer and not the argument (e.g., The Reverend Dr. Smith is a known Biblical fundamentalist, so her objections to evolution need not be taken seriously) argument from authority (e.g., President Richard Nixon should be re-elected because he has a secret plan to end the war in Southeast Asia - but because it was secret, there was no way for the electorate to evaluate it on its merits; the argument amounted to trusting him because he was President: a mistake, as it turned out) argument from adverse consequences (e.g., A God meting out punishment and reward must exist, because if He didn't, society would be much more lawless and dangerous - perhaps even ungovernable. Or: The defendant in a widely publicized murder trial must be found guilty; otherwise, it will be an encouragement for other men to murder their wives) appeal to ignorance - the claim that whatever has not been proved false must be true, and vice versa (e.g., There is no compelling evidence that UFOs are not visiting the Earth; therefore UFOs exist - and there is intelligent life elsewhere in the Universe. Or: There may be seventy kazillion other worlds, but not one is known to have the moral advancement of the Earth, so we're still central to the Universe.) This impatience with ambiguity can be criticized in the phrase: absence of evidence is not evidence of absence. special pleading, often to rescue a proposition in deep rhetorical trouble (e.g., How can a merciful God condemn future generations to torment because, against orders, one woman induced one man to eat an apple? Special plead: you don't understand the subtle Doctrine of Free Will. Or: How can there be an equally godlike Father, Son, and Holy Ghost in the same Person? Special plead: You don't understand the Divine Mystery of the Trinity. Or: How could God permit the followers of Judaism, Christianity, and Islam - each in their own way enjoined to

From Distraction to Engagement: Wireless Devices in the Classroom - 0 views

  •  
    a. Finding a balance between technology and teaching has proved challenging in the traditional classroom. Some institutions, such as University of Chicago Law School, have altogether banned internet access in the classroom, claiming that it imposes on the integrity of the education. Although the authors draw attention to research demonstrating the rampant frequency of distractions with laptop and mobile technology amongst students, they beg the question of whose fault it really is - and begs educators to reflect on their own teaching, and the educational institution as a whole. Fang describes possible solutions for the distraction dilemma for educators to apply to the modern classroom. Filtering applications can help to create a temporary filter on computer applications to ensure a singular task, or set of permitted tasks, are accessed. Network switching allows faculty and network administrators to determine which, if any, applications can use a network at a given time. Social solutions can also be effective; by educating the student on the issue of technology-related distraction in classrooms, and assessing teaching styles, class formats and institutional practices. In the modern classroom, the professor and technology should coexist peacefully; yet it will take social and technical finesse in order to find the right balance for the maximum benefit of the student.

    I chose the Open Educational Resources Research Hub (OER Research Hub) for a focus for research, designed to give answers to the overall question 'What is the impact of OER on learning and teaching practices?' and identify the particular influence of openness. As open education now reaches a stage of maturity we need evidence about what works, what doesn't and why in order that lessons learned can be shared. Filling the gap in the evidence base and sharing data and methods widely is the intention of OER Research Hub. The project combines: A targeted collaboration program with existing OER projects An international fellowship program Networking to make connections A hub for research data and OER excellence in practice

Digital Colonialism & the Internet as a tool of Cultural Hegemony - 1 views

  •  
    An article by an anonymous author on the Knowledge Commons Brasil. The article attempts to show how the Global North dominates the internet. Internet users as well as content (exemplified by geo-located entities) tend to cluster in the rich industrial countries of the so called "developed" wordl. This critique resembles the lament of the so called Media Imperialism spearheaded by the McBriede Report to Unesco (http://unesdoc.unesco.org/images/0004/000400/040066eb.pdf) "Many Voices, One World)". It should be noted that here more detailed studies suggested that news agencies reflect the interests of their audiences. So it would be interesting what the distribution of geo-tagged entities in the Igbo version of Wikipedia is like. Does it mirror a bias towards West Africa (Igbo being one of the principal languages of Nigeria)?

    Coincido con la reflexión de este artículo acerca de la necesidad de las casas editoras (publishers) de repensar sus modelos de negocios y de olvidarse (aferrase sería una palabra más precisa) del exclusivo modelo gutenberiano de producción editorial. Sin embargo, me parece que su enfoque adolece de varios problemas. El más notorio es que trata al mundo de las publicaciones como uno solo, cuando no hay forma de comparar las dinámicas, capitales (humanos, financieros y simbólicos) puestos en juego en la publicación académica (scholarly publishing) o en los libros de interés general (trade), guías turísticas, enciclopedias, libros religiosos, textos para niños, etc., para no mencionar la abismal distancia entre las revistas académicas (scholarly journals) y los libros o inclusivo las revistas generalistas (magazines). Concluir que las cosas van maravillosamente bien porque un montón de empresas, vinculadas a los medios masivos (un punto relevante en la argumentación, que se menciona como si fuera lo más normal del mundo) tienen emprendimientos exitosos es confundir peras con manzanas. También creo que usar el mantra de la época de la disruption (age of disruption) para todo aporta poco a la discusión (http://www.newyorker.com/magazine/2014/06/23/the-disruption-machine?currentPage=all)
  •  
    I agree with the reflection of this article about the need for publishers to rethink their business models and forget the exclusive Gutenberian publishing model. However, I think his approach suffers from several limitations. The most notorious is treating the publishing world as one, when there is no way to compare the dynamics, capital (human, financial and symbolic) at stake in academic or scholarly publishing with books of general interest (trade), tour guides, encyclopedias, religious books, textbooks for children, etc., not to mention the abysmal gap between scholarly journals and books or inclusive commercial magazines. Conclude that things are going wonderfully well because a lot of companies, linked to the mass media (an important point in the argument, mentioned as if it were the most normal thing in the world) have successful ventures is to confuse the things. I also believe that using the mantra of the age of disruption for all contributes little to a seroius discussion (http://www.newyorker.com/magazine/2014/06/23/the-disruption-machine?currentPage = all)

    Good read, Kevin! :) I agree with this article that said "As long as people want to be informed, entertained, and inspired, there will be profitable opportunities in publishing."

    The different approach needed to market traditional educational resources and OER

    Thank you for sharing. The article highlight a real-life problem. I am sure in my country many faculty members and librarians of higher educational establishment are not aware of OER and therefore they prefer safe and sure textbooks. Librarians should be first to explore, understand and market this type of resources. At the same time time may be needed in order to change educational policy and choice of textbooks.

    8 elements of digital literacy This video has merit despite the some of the distractions which divert the viewers' attention from the valuable content. Belshaw's introduction of his topic and objectives are clearly identified when he's in the street, he then walks into a building (at an accelerated time speed), sits down to describes the difference between the traditional mode of literacy found in print and books to that of digital media e.g. smart phones. This works well until he's suddenly in a railway station and later back in the street with all the commotion linked to these settings. This makes it very difficult to hear what is being said. However, his re-cap of at the end is helpful. Although reading and writing is necessary in both traditional and digital milieus, this is in figurative sense with the digital setting. There are numerous definitions for digital literacy (DL), but he describes digital literacy as being "a social linguist construct" rather than an intellectual concept. He describes an intersection between information and digital literacy. DL is divided into 8 elements: Cultural, Cognitive, Constructive, Communicative, Confident, Creative, Critical and Civic. The order of importance of the elements is dependent on the context in which the DL is found. There is no one correct choice as geography and networks have an impact.

    This video does a good explanation about the difference between data, information, and knowledge. In our class discussions, we talked about the differences too, which I never knew there were any. So data is just the facts of the world, information is capturing data within the context, and knowledge is what we know about plus our experiences.

Harvard University admits to secretly photographing students - 11 views

  •  
    I think, its really an expensive and unnecessary experiments, if the attendance of Harvard University is low, then they have to come up with different rule to attract the interest of students. Cameras should be there for security, but not for surveillance.
  • ...10 more comments...
  •  
    Similar example to what Adobe software has done with collecting information…users/students seem to have to accept this "new-normal" of spying, etc.
  •  
    I agree. Cameras should be there for security, not for surveillance. But just like the Adobe software, before we use it we have to "agree" on its' terms. I believe very few actually read those agreements, because we have to use the software, "agreeing" on those terms might just be "agreeing" on allowing them to collect our information. I live in Vancouver, BC. I know there are people who dislike the idea of the buses with cameras. I personally like that idea, it makes me feel like I am protected. When I was in high school in Victoria, BC, I feel safe taking the taxi even when it is late, because they have cameras in every one of them. When I was in Hong Kong, I feel insecure taking a taxi even when it is noon. So even if some of our information or our identity is given away, I agree on the idea of having cameras on buses and taxi's. I wonder if there is a gender difference on this, and there is also a gender gap of taxi drivers, maybe that is also why I personally feel insecure. Back to the point, if the purpose of cameras is for security, I agree to that. If it is for surveillance, I do not think it is essential; referring to the Harvard University attendance, at least they should inform the students about it.
  •  
    This line caught my eye: "The study was approved by the US federally mandated Institutional Review Board, which assesses research and determined that the study "did not constitute human subjects research" and therefore did not require prior permission from those captured by the study." I have been debating with my own campus IRB over what constitutes human subjects research and what doesn't--they seem to be operating under the idea that if it's not invasive medical studies involving blood or drugs, it's not really human subjects. I think the issue in this Harvard study is that the IRB also has a clause that if you are collecting data in public spaces and not interacting with the people there, it doesn't require IRB approval; the question is whether these classrooms should be considered public spaces. My feeling is they aren't--in order to be in a room at a particular time, a person has to have chosen to attend that class, and within college classes it is assumed that the students can know that what they say is to some extent private among their classmates and professor. Even if the photos were destroyed after analysis, the fact remains that there were cameras inside what I would consider private spaces, without the consent of the people doing what they might feel is dangerous work (given the current assault on public intellectuals and academic freedom). My guess is that Harvard could easily have asked all the relevant parties to sign consent forms at the beginning of a semester but not indicated on which days they would be filming--people would probably continue doing what they normally do either way, but at least would have the option of asking not to be filmed. There's always a way to set up an area in a lecture hall where the cameras couldn't reach, so students who didn't want to be on film could opt out.
  •  
    Thank you so much for sharing this article, I meant to read it a few days ago and got side-tracked!
  •  
    Thanks for sharing this! I have mixed feelings about this article. At first, I was super opposed to the whole initiative Harvard did to their students because I would feel that my privacy has been violated completely, but after realizing that there are many more subtler forms of violations in privacy online (social media sites, tracking cookies etc.) I wasn't as opposed to the article. Although initially, students were not informed about their surveillance, there were told in the aftermath, and their information was destroyed. When using social media sites or installing new applications, there are terms of agreement before continuing on with the installation in which personally I don't read at all. Those terms and conditions have statements inside which notify us of tracking personal information which I have not read earlier but am still not opposed to giving. The information is probably sold to advertisers and we're probably not aware of it but we still give them the information via the signup of the program. Hence, even though there are contradictory views and feelings about their initiatives, we should be more aware and cautious of other forms of surveillance when we sign up for things (e.g. social media sites etc.)
  •  
    Thank you for sharing. This does raise some concern. I guess there may be good and bad with cameras installed in the school. The cameras installed without students' consents may be violating their privacy and rights. However, it may prevent wrong doings, i guess. When my friend was doing final exam, the prof asked the whole class to put their belongings in front of the classroom, but when he went to pick up his stuff after he was finished, his bag was missing. Through the security camera, they were able to see who stole his stuff.

    Did any body else remember George Orwell's novel (1984). By accepting this type of behavior we accepting the image of a holly power that is ethical, care and neutral. Does this exist? and who will monitor the observers?
  •  
    I think this is a really good point, who will monitor the observers? What kind of power do those people hold and what are they doing with all those information? It makes people uncomfortable.
  •  
    Interesting news! It's surprising to get to know that Harvard University places cameras without letting students know, photographs them during lectures to measure attendance. This reminds me of my high school in China. When I was in high school, I remember that cameras were installed at the back of every classroom to prevent students from distraction in class or cheating during exams. It mainly worked as threatening students, from my understanding. Because you never know when the camera will be opened, actually, it never opened. What happened in Harvard University just reminded me of that, which is quite satiric.
  •  
    Thanks for sharing this article. In my personal opinion, I think the action of secretly installed the cameras from Harvard University violates students' privacy. If it's just for measuring classroom attendance, I think Harvard University could definitely find a much better way instead of installing the camera.
  •  
    wondering if this would be a different conversation if the cameras were just picking up heat signals so that the identity of the people could not be known but they could still be counted. The technology is pretty basic and it might even be more efficient than the way they're using them now.
  •  
    Can't believe Harvard can do this thing. I think informations are sharing and revealing on internet or others more and more serious. Harvard shouldn't secretly photograph students, they should ask permission first.
