Bioprinting

Bioprinting uses a 3D printing process to create synthetic human tissue. One day it could therefore be used to print replacement human organs. This video by Christopher Barnatt explores future medical and cosmetic bioprinting applications.

How to use Natural Networking to connect with anyone — including the exact email scripts

How to use Natural Networking to connect with anyone — including the exact email scripts | Wiki_Universe | Scoop.it

How many of us have heard career experts telling us to “go out there and network”?

 

What does that actually mean? They never seem to specify.

 

So we end up going to 1 or 2 pointless networking events, which actually turn out to be a bunch of unemployed people looking for jobs, until we realize the pointlessness of random networking. We stop going. But we keep hearing about the importance of our network, and we hear about how most jobs are found through personal contacts. Pretty soon, it becomes clear to us that it’s WHO you know, not WHAT you know. But we have no idea how to actually turn that realization into something actionable.

 

There’s a game going on around us that we don’t even see.

 

And today, I want to show you exactly how to decode it — along with the specific email scripts to use. If you’ve been waiting for the real story on how networking actually works, this is it.

Once we understand where the influencers are in a network we can start to undertand how to manage them, right? Im surely curious to understand the new cohort of students' networks
luiy's curator insight, March 14, 2013 12:31 PM

Centrality 

Often, regardless of the industry or organization performing social networking analysis, it is important to understand which models govern their specific target network. It is also critical to understand the smaller, local relationships between the actors (nodes). For example, for intelligence analysis purposes, it is critical to identify how information flows through the network and which nodes are the most active in collecting or sharing information. As such, a centrality of a network describes how important/influential a node is to a network.

 

 Highly central networks operate similar to highly centralized governments such as theocracies or monarchies while least centralized networks mimic democratic system of governments. The centralization of a network is approximately an average of the maximum centrality of a single node over the entire network and can be calculated by Freeman’s general formula.  For practical purposes, it is not always required to calculate this number to be able to realize the centrality of a network. For example, comparing today’s terrorist groups to traditional ones it can be observed without going through the calculations that today’s groups are much less centralized and hence harder to target. Low centralized networks, though sometimes not as effective in terms of governance and implementation of an overall strategy, are much more resilient (‘anti-fragile’) to shocks. For example, it’s much easier to contain a virus in a highly centralized network than it is in a low centralized network. The other concepts of centrality: ‘Closeness’ and ‘Betweenness’ attempt to measure the minimum number of nodes information or a meme would have to travel to get from one node to another. A very close network with many well-connected nodes (‘Betweenness’) would be much better and faster in communicating certain information, virus, knowledge, tradition, and meme across its entire network. A network with a very low ‘Closeness’ would hence be less effective and efficient in doing the same. 

Influence 

One of the most important outcomes of SNA is determining influencers across a network, as well as their level of influence. There are various ways to locate influencers such as number of followers, friends or connections as well as level of activity on social media. However more models are needed to better locate influencers.

How to Use the “Network Density” Formula to Measure the Health of a Community

How can you determine the health of a community?

A lot of community managers just go with their gut on this one, or use proxy metrics like signups, posts per day, klout scores, retweets or some other metric that is fairly hollow, but there are better ways.

This is very much a work in progress, so I’d love to collaborate. If anyone has any thoughts, please jump in the comments sections and let’s discuss. That being said, most of this isn’t new, it’s just stolen, adapted and generally simplified from concepts like Network Theory, Affinity Groups, Clustering Coefficients, Small World Networks, and other things I will never fully understand or convince people to invest tech into.

Let’s dig in…

What is Network Density?

First off, Network Density (ND for short) isn’t one number, it’s more like blood pressure where they say “80 over 120″. I have no idea what the 80 or the 120 mean, but it works as an analogy. So, with that in mind, ND breaks down roughly as:

Average Distance Between Users : Number of Paths : Frequency of Interactions

or simply put…

AD : NP : F

Lets break each part down…

The researchers used such linguistic measures as how an individual uses the first person singular pronoun (e.g. “I”, “I’ve”, “me”, “mine”), which has been shown to increase as a speaker interacts with someone of higher status. The researchers found that the technical skill-based roles, such as those of programmers and analysts, elicited higher levels of respect than those of more managerial roles

Concepts and technologies for tracking bioactive compounds in natural product extracts: generation of libraries, and hyphenation of analytical processes with bioassays

Concepts and technologies for tracking bioactive compounds in natural product extracts: generation of libraries, and hyphenation of analytical processes with bioassays | Wiki_Universe | Scoop.it

Since the advent of high-throughput screening (HTS) in the early 1990s, a wealth of innovative technologies have been proposed and implemented for the effective localization and characterization of bioactive constituents in complex matrices. The latest developments in this field are reviewed under the perspective of their applicability to natural product-based drug discovery. The approaches discussed here include TLC-based bioautography, HPLC-based assays with on-line, at-line and off-line detection, as well as affinity-based methods, such as frontal affinity chromatography, pulsed ultrafiltration mass spectrometry, imprinted polymers, and affinity capillary electrophoresis. Selected practical examples are given to illustrate the strengths and limitations of these approaches in contemporary natural product lead discovery. In addition, compatibility issues of natural product extracts and HTS are addressed, and selected protocols for the generation of high quality libraries are presented.

G+ is catching up big time for many reasons.  Among these reasons is the Hangout integration.  

 

We just facilitated a remote 1.5 day leadership development session with Hangouts and it was fantastic.  

 

Google is sticking to their strategy and their value is starting to win people over.  I was never a fan and, through valuable features, I am changing my perspective on the suite of offerings.

 

This is a relevant infographic.

From preschool to graduate school, if you are a classroom educator the term “flip” teaching has crossed, or is about to cross your path. Formally defined in the literature by Lage, Platt and Treglia (2000) as the “Inverted Classroom”, the catalyst for initial research was a need, particularly at the university level, to address a detrimental mismatch observed between instructor pedagogy and student learning style.
