Анализът на масивите данни може да помогне на редица бизнеси да решават проблеми и да намаляват загубите и пропуснатите ползи, твърди Александър Ефремов
1. Blogger – It’s free and easy to set-up. It can be integrated into your Google Apps for Education account which means that you and your students can use the same usernames and passwords that they use in all other Google tools. You can make your blog private (up to 100 members invited by email). The drawback to it is that a lot of school filters flag it as “social media” and block it on those grounds.
1a. Edublogs – Probably the best option for elementary school and middle school use. Blogs and individual blog posts can be made private, password-protected, or public. You can create and manage your students’ accounts. The latest version of Edublogs allows all users to include videos in blog posts. Outstanding customer support.
2. Weebly for Education – It’s free to have up to 40 students in your account. You can manage your students’ accounts. You can have students contribute to a group blog and or let them manage their own individual blogs.
3. SeeSaw.me – SeeSaw was originally launched as a digital portfolio tool. The addition of a blogging component was made in January 2016. The blogging component of SeeSaw allows you to import and display your students’ digital artifacts publicly or privately. There is not much you can do with SeeSaw in terms of customization of layout and color scheme.
4. WordPress.org – If you have the technical accumen or the time to learn it (it’s not that hard), self-hosting a blog that runs on WordPress software will give you the ultimate in control and flexibility. You will be able to create and manage student accounts, have a nearly infinite variety of customizations, and you’ll be able to move your blog from server to server whenever you want to. That said, you will have to pay for hosting (or convince your school to give you server space) and you will be responsible for maintaining security updates and backing-up your blog regularly.
5. Kidblog – Allows you to manage your students’ accounts. Requires you to pay for a subscription in order to get the features that you really want. Those features include embedding videos and other media from third party sites. Powered by WordPress software.
6. WordPress.com – It’s easy to use and is free, but with some serious limitations at the free level. The free version displays advertising on your blog which you cannot control. The free version also doesn’t allow embedding content from many third-party sites.
The 188-page “Challenging Government Hacking In Criminal Cases” report, released by the American Civil Liberties Union on March 30, addresses new amendments to Rule 41 of the Federal Rules of Criminal Procedure, which took effect last December.
Under the changes to criminal procedure rules, feds can remotely search computers in multiple jurisdictions with a single warrant. The rules are touted by law enforcement agencies as a way to streamline 100-year-old rules of criminal procedure
Because the questionnaire data comprised both Likert scales and open questions, they were analyzed quantitatively and qualitatively. Textual data (open responses) were qualitatively analyzed by coding: each segment (e.g. a group of words) was assigned to a semantic reference category, as systematically and rigorously as possible. For example, “Using an iPad in class really motivates me to learn” was assigned to the category “positive impact on motivation.” The qualitative analysis was performed using an adapted version of the approaches developed by L’Écuyer (1990) and Huberman and Miles (1991, 1994). Thus, we adopted a content analysis approach using QDAMiner software, which is widely used in qualitative research (see Fielding, 2012; Karsenti, Komis, Depover, & Collin, 2011). For the quantitative analysis, we used SPSS 22.0 software to conduct descriptive and inferential statistics. We also conducted inferential statistics to further explore the iPad’s role in teaching and learning, along with its motivational effect. The results will be presented in a subsequent report (Fievez, & Karsenti, 2013)
The 20th century notion of conducting a qualitative research by an oral interview and then processing manually your results had triggered in the second half of the 20th century [sometimes] condescending attitudes by researchers from the exact sciences.
The reason was the advent of computing power in the second half of the 20th century, which allowed exact sciences to claim “scientific” and “data-based” results.
One of the statistical package, SPSS, is today widely known and considered a magnificent tools to bring solid statistically-based argumentation, which further perpetuates the superiority of quantitative over qualitative method.
At the same time, qualitative researchers continue to lag behind, mostly due to the inertia of their approach to qualitative analysis. Qualitative analysis continues to be processed in the olden ways. While there is nothing wrong with the “olden” ways, harnessing computational power can streamline the “olden ways” process and even present options, which the “human eye” sometimes misses.
Below are some suggestions, you may consider, when you embark on the path of qualitative research.
excellent guide to the structure of a qualitative research
Palys, T., & Atchison, C. (2012). Qualitative Research in the Digital Era: Obstacles and Opportunities. International Journal Of Qualitative Methods, 11(4), 352-367.
Palys and Atchison (2012) present a compelling case to bring your qualitative research to the level of the quantitative research by using modern tools for qualitative analysis.
1. The authors correctly promote NVivo as the “jaguar’ of the qualitative research method tools. Be aware, however, about the existence of other “Geo Metro” tools, which, for your research, might achieve the same result (see bottom of this blog entry).
2. The authors promote a new type of approach to Chapter 2 doctoral dissertation and namely OCR-ing PDF articles (most of your literature as of 2017 is mostly either in PDF or electronic textual format) through applications such as
Abbyy Fine Reader, https://www.abbyy.com/en-us/finereader/
OmniPage, http://www.nuance.com/for-individuals/by-product/omnipage/index.htm
Readirus http://www.irislink.com/EN-US/c1462/Readiris-16-for-Windows—OCR-Software.aspx
The text from the articles is processed either through NVIVO or related programs (see bottom of this blog entry). As the authors propose: ” This is immediately useful for literature review and proposal writing, and continues through the research design, data gathering, and analysis stages— where NVivo’s flexibility for many different sources of data (including audio, video, graphic, and text) are well known—of writing for publication” (p. 353).
In other words, you can try to wrap your head around huge amount of textual information, but you can also approach the task by a parallel process of processing the same text with a tool.

Here are some suggestions for Computer Assisted / Aided Qualitative Data Analysis Software (CAQDAS)for a small and a large community applications):
text mining: https://en.wikipedia.org/wiki/Text_mining Text mining, also referred to as text data mining, roughly equivalent to text analytics, is the process of deriving high-quality information from text. High-quality information is typically derived through the devising of patterns and trends through means such as statistical pattern learning. Text mining usually involves the process of structuring the input text (usually parsing, along with the addition of some derived linguistic features and the removal of others, and subsequent insertion into a database), deriving patterns within the structured data, and finally evaluation and interpretation of the output. https://ischool.syr.edu/infospace/2013/04/23/what-is-text-mining/
Qualitative data is descriptive data that cannot be measured in numbers and often includes qualities of appearance like color, texture, and textual description. Quantitative data is numerical, structured data that can be measured. However, there is often slippage between qualitative and quantitative categories. For example, a photograph might traditionally be considered “qualitative data” but when you break it down to the level of pixels, which can be measured.
word of caution, text mining doesn’t generate new facts and is not an end, in and of itself. The process is most useful when the data it generates can be further analyzed by a domain expert, who can bring additional knowledge for a more complete picture. Still, text mining creates new relationships and hypotheses for experts to explore further.

Starbird argues in a new paper, set to be presented at a computational social-science conference in May, that these “strange clusters” of wild conspiracy talk, when mapped, point to an emerging alternative media ecosystem on the web of surprising power and reach.
There are dozens of other conspiracy-propagating websites such as beforeitsnews.com, nodisinfo.com and veteranstoday.com.
It isn’t a traditional left-right political axis, she found. There are right-wing sites like Danger & Play and left-wing sensationalizers such as The Free Thought Project. Some appear to be just trying to make money, while others are aggressively pushing political agendas.
The true common denominator, she found, is anti-globalism — deep suspicion of free trade, multinational business and global institutions.

The News Literacy Project
A Stanford studyfound that the majority of middle school students can’t tell the difference between real news and fake news. In fact, 82 percent couldn’t distinguish between a real news story on a website and a “sponsored content” post.
The WSJ: Of the 8,704 students studied (ranging in age from middle school to college level), four in ten high-school students believed that the region near Japan’s Fukushima nuclear plant was toxic after seeing an unsourced photo of deformed daisies coupled with a headline about the Japanese area. The photo, keep in mind, had no source or location attribution. Meanwhile, two out of every three middle-schoolers were fooled by an article on financial preparedness penned by a bank executive.
Using Ursula Le Guin short story “The Ones Who Walk Away from Omelas,” has allowed Fruchter to make his computer science math classes entirely project-based, which in turn draws the interest of kids who might not have otherwise liked computer programming.
teaching computer programming with fiction into a curriculum called StoryCode. He classifies STEM fiction into three categories: explicit, science fiction and implicit STEM texts.
“When you can call a line of code a spell, then you are getting somewhere,” Fruchter said. After all, isn’t computer code basically modern magic?

The paradox, of course, is that because our notion of history is rooted in the written record, words are both our instrument of truth and our weapon of distortion. We use them both to reveal and to conceal — a duality which Hannah Arendt so memorably dissected in her meditation on lying in politics.
Storytelling is a tool for knowing who we are and what we want, too. If we never find our experience described in poetry or stories, we assume that our experience is insignificant.

The versatility and compatibility of PowerPoint is a primary selling point for many presenters. Since it functions with both Microsoft Windows and Mac OS, PowerPoint is especially ideal for users intending to distribute their presentation out to other individuals and groups. Compared to Keynote and Prezi, PowerPoint has robust design options and multimedia capabilities. Through this program, users are able to follow a simple process to add audio and video clips to their slides.
Cons
Although PowerPoint is compatible across both Mac and PCs, the quality of the program is not created equal on each system – with the Mac version falling short of the PC version. On the design front, what PowerPoint makes up for in design options, it lacks in design function. Plus, audiences may perceive PowerPoint templates and themes as outdated
Keynote
Pros
For those well-versed in Mac applications, Keynote will be breeze. Beginning presenters, along with veterans who are pressed for time will also appreciate the ease of Keynote. Equipped with templates with built-in layouts into the themes, Keynote allows its users to essentially knock out two birds with one stone. Are you featuring animations in your deck? Keynote handles these much better than PowerPoint or Prezi. Compared to PowerPoint, Keynote boasts more elegant, sleek templates and design features powered by Adobe programs. If you want to save your Keynote presentations as a YouTube video or Quicktime slideshow, there will be no hassle involved in the effort.
Cons
PC users might really struggle with Keynote upon first introduction. For example, the application’s design tools are nested in dropdown menus and tabs, possibly foreign to the avid PC user.
Prezi
Pros
Prezi is a useful option for particularly storytelling-driven presentations. It’s non-linear storytelling capabilities far surpass the offerings in either PowerPoint or Keynote. From integrating multimedia and pngs and vector images constructed outside the web-based application fairly seamlessly to allowing collaboration among team members invested in the presentation, Prezi provides unique design and distribution capabilities. This presentation-building option also adds movement to a presenter’s message, which could be particularly engaging in many settings.
Cons
While Prezi’s web-based format provides simple embedding processes for blogs and web pages, any disruption in Internet connection or tiny glitch can reduce design quality and functionality. Even utilizing the zoom functions within Prezi can lead to fuzzy and pixelated photography. Some audiences could find the zoom functions gimmicky, while others could succumb to motion sickness. Designing within Prezi can be a challenge too, as users are limited to a set amount of colors and fonts and shapes are difficult to manipulate.
