    1. Four studies (Andreescu et al., 2013; Li et al., 2013; Posner et al., 2013; Liston et al., 2014) found DMN hyperconnectivity in depressed patients with respect to the control subjects. In all of them, connectivity reductions were observed in DMN after the treatment (Li et al., 2013; Posner et al., 2013; Liston et al., 2014)

      Hyper connectivity in depression =4 Post treatment change = All except 1 showed decreased

    2. hyperconnectivity of DMN and the SN with CCN is related to rumination in depression (Jacobs et al., 2014).

      hyper DMN-SN/CNN and rumination

    3. It has been linked to self-reference processes and their alteration; while the pathological interactions of DMN with other networks such as the SN and the CCN would be linked to the states of pathological rumination frequently presented by depressed patients (Broyd et al., 2009; Belleau et al., 2014; Jacobs et al., 2014).

    1. Here are the economics: The cost of recruiting a midcareer software engineer (who earns $150,000- 200,000 per year) can be $30,000 or more including recruitment fees, advertising, and recruiting technology. This new hire also requires onboarding and has a potential turnover of two to three times higher than an internal recruit. By contrast, the cost to train and reskill an internal employee may be $20,000 or less, saving as much as $116,000 per person over three years.  The net savings: it can cost as much as 6-times more to hire from the outside than to build from within.

    1. Preferences DataStore and Proto DataStore DataStore provides two different implementations: Preferences DataStore and Proto DataStore. Preferences DataStore stores and accesses data using keys. This implementation does not require a predefined schema, and it does not provide type safety. Proto DataStore stores data as instances of a custom data type. This implementation requires you to define a schema using protocol buffers, but it provides type safety.

      Currently, I am using SharedPreference which is still alright to use. However, there is a better option called DataStore. This allows data to be stored asynchronously.

    1. A crucial difference between representations of relative error inthese equations compared withEquations 6and7 for the single-facet designs is that three sources of measurement error varianceare separately represented, withpt2ntequaling specific-factor error,po2noequaling transient error, andpto,e2ntnoequaling random-responseerror. Effects fortasks, occasions, and their interaction are includedin the denominator for the D-coefficient but not the G-coefficientbecause those effects can change the absolutemagnitude of scoresbut not their relative differences.
    1. Many companies view L&D as a service provider for employees instead of a strategic partner for growth

      I've talked about this before when brain storming on how to teach companies to become teaching organizations, and partnering more closely than one-off training that is very off the shelf.

    1. Micromachines always focused on local multiplayer, and the fun their eccentric races of small toy vehicles competing on tracks made with everyday objects; and all that is present.
    2. game that uses the Micro Machines license to try and sucker people in that remember the old games.

    1. The privacy policy — unlocking the door to your profile information, geodata, camera, and in some cases emails — is so disturbing that it has set off alarms even in the tech world.

      This Intercept article covers some of the specific privacy policy concerns Barron hints at here. The discussion of one of the core patents underlying the game, which is described as a “System and Method for Transporting Virtual Objects in a Parallel Reality Game" is particularly interesting. Essentially, this system generates revenue for the company (in this case Niantic and Google) through the gamified collection of data on the real world - that selfie you took with squirtle is starting to feel a little bit less innocent in retrospect...

    1. what's happening at the college level which is a bit different than at the university level

      Another important point. Our college-based network is leading some OER initiatives, these days. Partly because our needs are quite specific. Most of the OER scene focuses on universities (or merges colleges and universities, since they are very similar in some contexts).

    1. Hub-and-spoke is the dominant logistics model because it is the only cost-effective way of sending a package over 10 miles. The downside of hub-and-spoke is that it is not very flexible. Delivery times are determined by other deliveries within the network and on a delivery route

    1. In a 1772 letter to Joseph Priestley, Franklin lays out the earliest known description of the Pro & Con list,[100] a common decision-making technique, now sometimes called a decisional balance sheet:

      I still use this method today. In my job, we use it to decide on possible courses of action - weighing the pros and cons of each against another.

    1. I would much rather have a "cosine" module than a "trigonometry" module because chances are good I only need a small fraction of the utilities provided by the larger trig module.
    2. Small modules are extremely versatile and easy to compose together in an app with any number of other modules that suit your needs.
    3. Write modules that do one thing well. Write a new module rather than complicate an old one.

      .

    4. Second, I don't agree that there are too many small modules. In fact, I wish every common function existed as its own module. Even the maintainers of utility libraries like Underscore and Lodash have realized the benefits of modularity and allowed you to install individual utilities from their library as separate modules. From where I sit that seems like a smart move. Why should I import the entirety of Underscore just to use one function? Instead I'd rather see more "function suites" where a bunch of utilities are all published separately but under a namespace or some kind of common name prefix to make them easier to find. The way Underscore and Lodash have approached this issue is perfect. It gives consumers of their packages options and flexibility while still letting people like Dave import the whole entire library if that's what they really want to do.
    1. Microlibraries are easier to understand, develop and test. They make it easier for new people to get involved and contribute. They reduce the distinction between a “core module” and a “plugin”, and increase the pace of development in D3 features.
