Die HBR hat schlechte Nachrichten für umweltbewußte Neuwagenkäufer: falsch gedacht! Das neue Auto hat in Summe die persönliche Ökobilanz und den Carbon Footprint so belastet, dass der geringere Verbrauch möglicherweise nichts mehr retten kann. Schade, eigentlich.
To Help the Environment, Keep Your Clunker
Thinking of junking your old car and buying a new fuel-efficient model to help the environment? Don’t overlook the CO2 emissions produced by automobile manufacturing. A one-year decrease in a car’s lifetime leads to a reduction in overall carbon emissions only if the new replacement car is at least 12.7% more fuel-efficient than the old one, say researchers led by Shigemi Kagawa of Kyushu University in Japan. That’s an increase from, say, about 12.1 kilometers per liter (28.4 miles per gallon) to 13.6kpl (32mpg).
Also, unglaublich: offensichtlich beeinträchtigt Fasten die Denkleistung. Ich bin zwar ohne Essen im Unterzucker irgendwann einmal grantig, hoff aber doch, dass das logische Denken nicht in diesem Ausmaß leidet:
Dieters Believe Adding a Salad Will Reduce a Meal’s Calories
Weight-conscious people are more likely than others to cling to the illusion that adding a healthy option such as a salad decreases a meal’s caloric content. Diners who are highly concerned about their weight falsely believe, on average, that addition of a healthy item makes a meal13.5% less calorie-rich, compared with just 3.8% for people who are not as weight-conscious, says a study by Alexander Chernev of Northwestern University. Chernev says the misguided belief that a healthy meal will reduce weight gain is an important factor in the obesity epidemic.
Das Problem mit Spam ist schnell erklärt: Es funktioniert (leider). Sie glauben das nicht? Wirklich blöd, ist aber so. Und der Spaß: wir bekommen mehr als eine Nachricht …
Die HBR hat’s berichtet:
What It Takes to Sell a Little Viagra via Spam
It takes 12.5 million spam e-mail messages to sell $100 worth of Viagra, according to research cited by The New York Times. The research also found that a single commercial spam campaign can generate as many as 3 messages for every person on Earth.
Women make fewer phone calls than men, but their calls last 16% longer, according to a study of 3,103 mobile-phone customers in Italy and Greece.
Guido Friebel of Goethe University in Germany and Paul Seabright of the Toulouse School of Economics in France also looked at call-center employees in Germany and found that calls allocated to women lasted 15% longer than those routed to men; these female employees were just as effective as the men, the
researchers found.
