Every Thursday afternoon, maids deliver white sheets to guest rooms at Hedonism II in Negril. But these sheets are not for the beds. They're for the guests to wear to dinner that night.

"No sheet, no eat" is the motto of the weekly toga party at this resort known for its adults-only atmosphere. Hedonism II attracts fun-loving couples and singles over age 18 who come to this westernmost point of Jamaica for a vacation of sun, sand and something more. Guests leave their inhibitions behind, seeking pleasure in the form of festivities like Toga Night, buffets to tempt the most devoted calorie counters, bars open until 5 am, and nonstop adult fun.

On Toga Night, some people sport traditional modest Roman wraps, but variations abound, most revealing plenty of sunburned skin. Don't be surprised to see women lining up at the buffet wearing topless micro-togas or men leaning against the bar wearing the kind of getups rarely seen outside a sumo wrestling ring. Hedonism's credo is that "a vacation should be whatever you want it to be," and for some that means a break from the cares and even the clothes of the everyday world.

Exercises 29.1 through 29.5 to each group, and one of Exercises

29.2 through 29.5 to each member.

3. Explain that each group has 20 minutes in which to reach a decision.

4. After the time has elapsed, call the groups back together to hear the decision that each group reached.

Trainer Guidance

This activity is useful in examining priorities and decision making as well as being an obvious icebreaker.

If you use this activity as an icebreaker, there is no need to hand out the character role plays; instead let the participants use factual information about themselves.


After listening to the decision that each group reached, ask them to explain their reasoning. This activity may be used in conjunction with Activity 22.

Ask the participants to suggest ways in which this situation could have been avoided. It is possible that none of the travelers have made contingency plans, trained other people to be able to complete an important part of their job, or delegated.

From Tradition to Modernism A Reinterpretation of Classical Works

Victoria Charles Parkstone International ePub


Modiglianis first teacher, Guglielmo Micheli (died 1926), was a follower of the Macchiaioli school of Italian Impressionists. Modigliani learned both to observe nature and to understand observation as pure sensation. He took traditional life-drawing classes and immersed himself in Italian art history. From an early age he was interested in nude studies and in the classical notion of ideal beauty.


In 19001901 he visited Naples, Capri, Amalfi, and Rome, returning by way of Florence and Venice, and studied first hand many Renaissance masterpieces. He was impressed by trecento (13th century) artists, including Simone Martini (c.12841344), whose elongated and serpentine figures, rendered with a delicacy of composition and colour and suffused with tender sadness, were a precursor to the sinuous line and luminosity evident in the work of Sandro Botticelli (c.14451510). Both artists clearly influenced Modigliani, who used the pose of Botticellis Venus in The Birth of Venus (1482) in his Standing Nude (Venus) (1917) and Red-Haired Young Woman with Chemise (1918, p.16), and a reversal of this pose in Seated Nude with Necklace (1917, p.17).

El Petén

Shelagh McNally Hunter Publishing ePub

Once inhabited by several million people, El Petn Valley was the center of the Maya civilization for centuries. Researchers believe this area, known as the southern Maya lowlands (now Belize, northern Guatemala and eastern Mexico), had the densest population. It reached its gold4en era during the Late Classic period (AD 600-900). Between AD 650 and 930, various city-states, such as El Mirador, Tikal, Dos Pilas, Ceibal and Yaxh, emerged from the jungle as mighty forces whose influence was felt as far north as Chichn Itz in Mexico's Yucatn. The struggle for power spawned many wars and the chronicles of victories and defeat are recorded in the stelae on buildings, pyramids and staircases. Yet for all its power and wealth, the southern Maya lowlands area was deserted by AD 930. Theories continue to evolve with each new discovery and researchers believe this area may hold the answer to the mysterious disappearance of the civilization.

Overlooked for centuries, El Petn holds a lost kingdom that is only starting to come to light. During the 18th century, both Spain and Britain attempted logging in the Petn, but the remoteness and lack of roads made any real development difficult to maintain. Ninety percent of virgin rainforest remained until 1970. The civil war that raged from 1960 until 1996 actually helped preserve the area, since the rebels set up base camps in the Petn and discouraged anyone else from settling there. During the 1980s, the Guatemala government decided the Petn was the solution for the many displaced survivors of the war and encouraged homesteading by selling parcels of land for as little as Q175 (US $25). At the same time it allowed oil and logging companies to start building roads through forests. As a result, over 400,000 misplaced Guatemalans arrived to claim their piece of land. Today, half of the rainforest has been cut down by either logging companies, cattle barons or by settlers practicing slash-and-burn agriculture. All are devastating. This is not the Promised Land for settlers the poor soil quality forces residents to hunt for survival. The end result has been a drastically reduced wildlife population. White-tailed deer, tepezcuintle (an agouti paca), jaguars and ocellated turkey are in danger of disappearing from El Petn.
