Child Artistic Development: From Scribbles to Realism
The Scribbling Stage: Early Artistic Expression
Scribbling
Scribbles are the first shapes of child art. They appear when a child holds a marking instrument and moves it with muscular variations of the hand or the arm. Before scribbling, children have done similar movements playing with their fingers in sand or any other surface (e.g., spilled milk on a table). In this sense, a scribble is a mark or a trace.
There is an increasing interest in research on the scribbling stage, which is considered a crucial

Flow Measurement: Pitot and Prandtl Tubes
Explain and describe the basic methods of flow measurement: Pitot tube and Prandtl tube:
Pitot tube: Measures the total (stagnation) pressure at a point.
Prandtl tube: Combines total and static pressure measurements to calculate the local velocity of the fluid using Bernoulli’s equation.
Obstruction Meters and Discharge Methods
Obstruction meters (flow meters): These work by creating a pressure drop by narrowing the passage of the fluid. The main ones are the

RL and RC Circuit Transient Response Analysis
1.Derive the expression for Transient Response of RL Circuits
A
1. Circuit and assumptions
Resistance = R
Inductance = L
DC source = V applied at t=0
Initial current in inductor: i(0)=0
2. Apply Kirchhoff’s Voltage Law (KVL)
For t>0:
V=Ri(t)+L di(t)/dt
Rearranging, L di(t)/dt+Ri(t)=V
3. Solve the differential equation
Step 1: Standard form: di(t)/dt+R/T i(T)=V/L
This is a first-order linear differential equation
Step 2: Complementary (homogeneous) solution
Di/

Effects of Globalization on Firms
2. Indicate five effects of globalization on the organization of firms.
- Offshoring and outsourcing of activities: Companies begin to relocate production to countries where production factors are cheaper. In addition, they start purchasing products that are more convenient to buy rather than produce themselves.
- Increase in competition: Due to the possible reduction in costs mentioned above, companies can carry out greater production. Having lower costs leads to lower

Essential Causal Inference and Econometrics Techniques
Randomized Experiments and Causal Inference
Why are randomized experiments so desirable?
Randomization breaks the link between treatment assignment and confounders, making treated and untreated groups exchangeable. This guarantees unbiased estimates of causal effects (on average) because any differences in outcomes can be attributed to the treatment rather than selection.
Why might we not be able to run a randomized experiment?
They may be unethical (e.g., denying beneficial treatments), infeasible
