ICU Severity Scoring Systems:
| Score | Full Name | Use |
|---|---|---|
| APACHE II | Acute Physiology and Chronic Health Evaluation II | ICU mortality prediction (first 24h data) |
| SOFA | Sequential Organ Failure Assessment | Organ failure tracking, sepsis diagnosis |
| SAPS II | Simplified Acute Physiology Score II | ICU outcome prediction |
| CURB-65 | — | Pneumonia severity (community setting) |
| GCS | Glasgow Coma Scale | Neurological status, not general ICU severity |
Static meanings is one of the behaviours of language that the textbook identifies as a communication problem. Languages attach meanings to words and associate characteristics with people, places, or groups — and these associations can persist long after they are no longer accurate or fair. The textbook gives these illustrative examples:
- A university classmate once regarded as “nuts” is still referred to as such by friends even years after he has matured and changed
- A traveller cheated once in a foreign country continues to call all people of that nation “cheats” decades later
- Historical ruling tribes described with certain characteristics have their descendants judged by those same labels for generations
This is contrasted with natural sciences like physics or chemistry, where measurements change objectively as conditions change. Language has no such automatic update mechanism — human bias preserves outdated associations, harming communication and perpetuating injustice.
Let $f:[0,1]\to\mathbb{R}$ satisfy $f(xy)=f(x)\cdot f(y)$ for all $x,y\in[0,1]$ with $f(0)\neq 0$. If $y=y(x)$ solves $\dfrac{dy}{dx} = f(x)$ with $y(0)=1$, find $y\!\left(\dfrac{1}{4}\right)+y\!\left(\dfrac{3}{4}\right)$.
From the functional equation $f(xy)=f(x)f(y)$ with $f(0)\neq 0$, putting $x=y=0$ gives $f(0)=f(0)^2 \Rightarrow f(0)=1$. Putting $y=0$: $f(0)=f(x)f(0) \Rightarrow f(x)=1$ for all $x$.
So $\frac{dy}{dx}=1$, giving $y=x+C$. With $y(0)=1$: $C=1$, so $y=x+1$.
$y(1/4)+y(3/4)=(1/4+1)+(3/4+1)=5/4+7/4=12/4=\mathbf{3}$
Enculturation is the natural, passive, lifelong process by which individuals absorb their own culture's values, language, norms, and beliefs — primarily from parents, family, community, and education. It is largely unconscious: the child does not choose to be enculturated; it simply happens through immersion. The Lahore example (Option C) perfectly illustrates this: a Pakistani child does not consciously choose to speak Urdu, observe Islamic practices, eat biryani, or respect elders — these are absorbed as part of growing up in that environment. Acculturation (Options A, B, D), by contrast, involves a conscious, deliberate effort to learn and internalise the norms of a different culture. The textbook notes that acculturation “may take years even to those who command some expertise on communication techniques.” Failure to acculturate leads to ongoing communication problems and possible cultural shock.
