The textbook presents a compelling economic analysis of beauty stereotyping in media: “By presenting an ideal difficult to achieve and maintain the cosmetic and diet product industries are assured of growth and profits.” Key facts cited:

• The diet industry alone is estimated to be worth $100 billion (U.S.) per year
• Research links exposure to unrealistic media body images to depression, loss of self-esteem, and eating disorders
• 35% of girls aged 6–12 had been on at least one diet; 50–70% of normal-weight girls believed they were overweight (Teen magazine, 2003)
• One in four college-aged women used unhealthy weight control methods

The textbook quotes activist Jean Kilbourne: “Women are sold to the diet industry by the magazines we read and the television programs we watch.” This case study illustrates how commercial stereotyping can have serious public health consequences, going far beyond mere aesthetic preferences.

This represents strategic HR management - aligning human resources (their distinctive competencies) with organizational strategy (mission). It moves HR from purely operational/administrative functions to strategic business partner role.

In 1922, a New York radio station ran what is considered the first commercial radio broadcast (a 10-minute promotion for co-op apartments). This established the commercial/advertising model for American radio. Britain took a different path. In 1923, the BBC was established using public taxes on radio receivers (later evolved into the television licence fee). This model was designed to fund programming without dependence on commercial sponsors, giving the BBC greater independence from market pressures and direct government control. The textbook notes: “Although most countries of that era also adopted government-sponsored radio broadcasting, the BBC and CBC are among the few that were able to insulate programming content from direct government influence.” In contrast, “most countries used radio to further the political aims of those in power.” The Canadian Broadcasting Corporation (CBC) was modelled after the BBC for similar reasons.

Calculate each time using the formula $\text{time} = \frac{\text{distance}}{\text{speed}}$:

• Column A: $t_A = \frac{d}{s}$
• Column B: $t_B = \frac{d/4}{2s} = \frac{d}{8s}$

To compare, find the ratio: $\frac{t_A}{t_B} = \frac{d/s}{d/(8s)} = \frac{d}{s} \times \frac{8s}{d} = 8$

So $t_A = 8 \times t_B$, meaning Column A is 8 times larger than Column B.

Therefore, Column A is greater.
