* Sound and light waves allow us to talk to and see each other

* Ultrasound and radiation waves have many applications in medicine

* Electromagnetic waves have given us radio, television, cordless and cell phones and all the gadgetry and allows us to text to and follow each other

DISCUSSION

All or most of us have either given or received the advice of “don’t make waves”. What this means is “don’t create a disturbance” because in physics the definition of a wave is “a disturbance that once created it travels in its own way and unique speed and cannot be altered”. How many of us wish if we could only take back something that we said…

There are many types of waves. There are the sound waves, which allows us to communicate with each other. As we speak we create a disturbance that travels through the air at the speed of sound (345 meters per second (m/s)) to the ears of all around us. Then we have water waves that we see in the rivers, ponds and the sea. And nature is full of electromagnetic waves (EM), visible light being part of the EM wave family its only special characteristic being that it excites our retina and allow us to see things. Other wise light is of the same nature as x-rays that destroy our retina. One peculiarity of all the different waves is that they are described by the same mathematical equation, very appropriately called “the wave equation”, a subject upon which we shall not elaborate here, but we shall note that the only difference is their speed of propagation (travel). As noted above sound waves travel at 345 m/s whereas EM waves travel at the speed of light or 300,000 kilometers per second (km/s) (186,000 miles/s).

It travels seven and a half times around the equator in one second!

Everybody wants to put more accountability into business; but this seems much easier said than done. For example, David Rock summarizes three different attempts to introduce values in corporate personnel behavior, and laments their lack of success by attributing the shortcomings to the innate complexity, if not irrationality, of human decision making (‘The Business of Values’). We take a more upbeat stance on human nature here, believing that society and its institutions can be guided by values – there is ample evidence of this among developing and developed cultures, and we do not think there is anything making us unfit for it.

Is, then, our current, less-than-ethical corporate behaviour a riddle that defies explanation? If we are capable of value-guided behaviour, why don’t we practice it in corporate environments? We believe there is an explanation for this. Personal and social values are built into our character, as Aristotle explained; they are acquired by training and habituation in early age, and exhibit themselves in our dispositions to feel, to decide, and to act in accordance with them. This is what Binta Niambi Brown discovered, when she felt impelled to disclose to her client crucial information that emerged just as the deal was being struck; “Even if the deal had been blown up for good, honest reasons rooted in decent integrity and morality” disposed her to reveal the information.

Greek NPL’s: Is there light at the end of the tunnel?

The year 2018 is a milestone for Greece, as it moves towards to the completion of the third economic adjustment program. That means that after the official end of the program in August 2018, Greece must take fate into its own hands, and try to borrow from the markets to meet its future debt obligations. As the country leaves behind the 8-year long memorandum era, the two main concerns for the Greek government and the banking sector are: a) a decision on the debt relief measures that should follow and b) a solution to the Non-Performing Loans (NPL’s) problem.

The International Monetary Fund openly declares what anyone with basic training in economics can see: Greece requires substantial debt relief from its European partners to restore debt sustainability. The main issue here is that the resolution of this problem mainly depends on political decisions from Greece’s EU partners that are hard to sell to their voters-tax payers. This is of outmost importance for the medium to long term stability of the Greek economy. On the other hand, the NPL’s problem is urgent and imperative.
