Billion Dollar Bully highlights why Yelp feels unfair. - 2 views

  •  
    The article extends beyond just discussing Yelp, to other community based internet knowledge platform sites like Wikipedia. Wikipedia is given a pass because it is nonprofit and has an active community dedicated to accuracy- review sites like Yelp and Google have financial considerations that possibly impact their ability to be totally impartial. Do you rely on online review sites? How much weight do you give them when making decisions?

    I am a heavy user of Tripadvisor when I plan vacations and read hundreds of reviews on lodging, restaurants, and attractions. While I'm quite sure some of the reviews are fake, some of them are obviously fake or are done by persons who seem to be very disgruntled with life in general. When I look at reviews I prefer those that include photos and plenty of details. I tend to ignore the ones that just say things like "I hated it" or "I loved it" as they offer no real value.

    This is such an interesting topic! I am not a heavy user of review sites but seeing this (https://www.ratemyprofessors.com/) makes me feel strange.

The role of social media in higher education classes (real and virtual) - A literature ... - 3 views

  •  
    Tess (2013) provides a great review of the literature on the role of social media in the higher education context. Tess (2013) suggests that as instructors look for ways to incorporate technology to mediate and enhance their instructions as well as promote active learning among students, they increasingly turn to different social media tools. The author argues that the current literature on the integration of social media in higher education are limited to self-reported data and content analyses. Therefore, he provides a summary of literature on the role of social media in the higher education classroom as well as discusses their limitations. Various studies (cited below) explored the role of social media and SNSs in different contexts of education -teaching learning process. These studies have demonstrated interesting and useful results. Tess (2013), in addition to keyword-specific searches, used a "snowball" method for finding the articles from the relevant articles cited in the literature reviewed. To narrow the range of the review, he chooses articles on Facebook, MySpace, Twitter, blog and LinkedIn. Tess (2013) provides a brief definition of each of these five SNSs. He also looks at the social impact of these popular SNS tools. The author looks at the factors motivating the educators to use social media in higher education classrooms, such as: the changing nature of the student, the changing knowledge consumption relationship, and the de-emphasis of institutionally provided learning and emergence of "user-driven" education (Selwyn, 2010). The author provides platform-specific affordances and drawbacks in terms of their application in the higher education space. Tess (2013) argues that although the infrastructure to support social media's presence exists in most universities today, instructors have been slow in adopting the tool as an educational one. Those who are adopting are still likely in the experimental stage. He admits that his literature rev

Technology-supported peer feedback in ESL/EFL writing classes: a research synthesis - 1 views

  •  
    Many recent studies show the effectiveness of Web 2.0 technologies on collaborative writing for L2(ESL/EFL) students. Web 2.0 tools such as Wiki, Facebook, and Forum have been adopted in an L2 class to enhance students' motivation and achievement. Peer review and collaborative writing are drawing more attention and support from L2 instructors because of the collaborative potential of the latest CMC tools such as Wikis. With this latest technology, students can work more easily and simultaneously in groups of three or more than with previous technology. Check this article for the recent studies about using technologies in ESL/EFL writing classes for peer feedback projects.

  • Enabled by social media, individuals share their information; this then shapes social word of mouth in the form of informational or emotional support for the online communities. Users’ perceived usefulness in terms of caring and offering support through useful information make it essential for others to seek and share commercial information within the online communities (Crocker and Canevello 2008). Hence, sharing commercial information and empathising with the issues of other members of the community is likely to produce credibility and trust in the network and the adoption of social word of mouth; this may lead to the purchase intention.

  • . In addition, consumers use social media by participating in reviewing or recommending a product to other users; these activities further increase the usefulness of a platform (Kumar and Benbasat 2006). These opportunities attract individuals to online communities and it facilitates their involvement with peers in other communities.

Adverse Effects Associated with Protein Intake above the Recommended Dietary Allowance ... - 1 views

  • However, high protein diets (defined as an intake above the current RDA) are promoted intensively by the nutritional supplements industry and they are considered to be “the gold standard” by many athletes (especially bodybuilders) for muscle development and/or body fat loss.

  • On the other hand, several scientists claim that the overuse of protein supplements or high dietary protein intake could cause disorders to human health [1–7]. The aim of this review study is to determine the potential health dangers due to high protein/high meat intake obtained from diet or nutritional supplements based on the human studies existent in the literature.

      High protein potential danger to health
  • Extra protein is not used efficiently by the body and may impose a metabolic burden on the bones, kidneys, and liver. Moreover, high-protein/high-meat diets may also be associated with increased risk for coronary heart disease due to intakes of saturated fat and cholesterol or even cancer [

  • Diet which is high in protein generates a large amount of acid in body fluids [2]. The kidneys respond to this dietary acid challenge with net acid excretion, and, concurrently, the skeleton supplies buffer by active resorption of bone resulting in excessive calcium loss [2]. Moreover, acid loading directly inhibits renal calcium reabsorption leading to hypercalciuria in combination with the exorbitant bone loss

      High protein intake may lead to excessive bone loss.
  • igh levels of dietary protein, at least a portion of the increase in urinary calcium reflected increased bone resorption [1
  • There was a consistent increase in urinary calcium with the high-protein diet averaging 88% above control in the normals and 82% in the patients
  • An increase in urinary calcium excretion was found indicating that the animal protein-induced calciuric response could be a risk factor for the development of osteoporosis
  • An increase in vegetable protein intake and a decrease in animal protein intake may decrease bone loss and the risk of hip fracture [
  • Additionally, dietary excess (2 g/kg/day) in animal protein for 1 week led to significant changes in urinary calcium excretion rates
  • releases calcium to be excreted by the kidney. This protein-induced hypercalciuria could lead to the formation of calcium kidney stones
  • animal protein is also the major dietary source of purines, the precursors of uric acid. Excessive intake of animal protein is therefore associated with hyperuricosuria, a condition present in some uric acid stone formers [5]. Uric acid solubility is largely determined by the urinary pH. As the pH falls below 5.5 to 6.0, the solubility of uric acid decreases, and uric acid precipitates, even if hyperuricosuria is not present
  • animal protein-rich diet was associated with the highest excretion of undissociated uric acid due to the reduction in urinary pH
  • arian cancers. Thus, reducing red meat intake might lower the risk for several common neoplasms [26]. Moreover, highprotein/high meat diet could cause disorders of liver function and precipitated progression of coronary artery disease. Hyperalbuminemia and elevated transaminases have been associated with high-protein diet [27]. Individuals on high protein supplements developed intermittent abdominal pain, transient elevations in transaminases, and hyperalbuminemia without there being any identifiable cause.

      Most Twitter users are lurkers... what do you all think about that?
  • A new Pew Research Center study goes a step further. First, we asked survey respondents whether they use Twitter and, if so, for permission to look at their Twitter accounts. After reviewing each account, we quantified these Americans’ tweets, likes, followers and followings. The result is the Center’s first study of Twitter behavior that’s based on a representative sample of U.S. adults who use the platform.

    I can definitely see most Twitter users being lurkers. I lurk on Instagram quite a bit, but I have become more active in liking posts since taking this class!
  •  
    I am also an Instagram lurker. I was curious and looked at my three most recent posts... June 2, May 9, and March 2! Very little production happening.

    I am an invisible learner on Instagram. I have never posted on Instagram, but just like some of the posts. :-)

    I'm definitely a lurker when it comes to Twitter.

When I say … microlearning - PMC - 5 views

  • One of the barriers to the application of microlearning has been the lack of a consistent clear operational definition to guide instructors
  • Microlearning is short.
  • Microlearning focuses on a single learning objective.
  • ...4 more annotations...
  • Microlearning resources are most commonly and effectively delivered via digital technology (but microlearning is not defined by technology).
  • Microlearning can be achieved on the go when the learner wants it or needs it.
  • The Internet‐connected smartphone is a major driver of microlearning because it provides access to learning on the go (i.e. mobile learning) and is nearly always accessible to most people.
  • Microlearning on Web 2.0 applications also offers the benefit of a collaborative learning space.

    This is an interesting concept, I had not heard of microlearning before today. It sounds like there is some merit to it, based on this article, but I do wonder how easy it could be to use ineffectively in terms of corporate trainings. I worry it could be easy to see low cost numbers and embrace the concept without ensuring learning gains are still taking place.
