Answer:
L0ckdown measures have been introduced worldwide to contain the transmissi0n of C0VID-19.
A number of studies showed positive impacts of l0ckdown in China and European countries.
Although the term ‘l0ckdown’ is now ub1quitous, it is not well-defined.
There are also no clear definitions of commonly used adjectives for the term such as ‘total l0ckdown’ and ‘partial l0ckdown’; and ‘hard’ or a ‘soft’ l0ckdown.
We have define ‘l0ckdown’ using a two-by-two matrix based on whether measures are c0mpulsory or v0luntary; and whether they are targeted at ident1fiable individuals and facilit1es, or applied 1ndiscriminately to a general population.
We describe the design, timing and 1mplementation of l0ckdown in nine countries in sub-S4haran Afr1ca: Gh4na, N1geria, S0uth Afr1ca, S1erra Leo0ne, Sud4n, T4nzania, Ug4nda, Zamb1a and Z1mbabwe.
This paper highlights the need for intersect0ral and transd1sciplinary research capable of providing a rig0rous and h0listic assessment of the harms and benefits of l0ckdown.
In Escher's drawing, it is not clear whether the water is flowing away form the viewer or towards the viewer. In many ways, it seems to contradict the laws of physics. Moreover, the corner points of the cube above the structure are connected in such a way that it is not clear which points are the farthest and which are the closest to the viewer. In these ways, the artist plays with our perception of depth.
