Hypothesis testing controversy

Comments and recommendations regarding the hypothesis testing controversy

Hypothesis tests are routinely misinterpreted in scientific research. Specifically, the failure to reject a null hypothesis is often interpreted as support for the null hypothesis while the rejection of a null hypothesis is often interpreted as evidence of an important finding. Many of the most frequently used hypothesis tests are "non-informative" because the null hypothesis is known to be false prior to hypothesis testing. We discuss the limitations of non-informative hypothesis tests and explain why confidence intervals should be used in their place. Several examples illustrate the use and interpretation of confidence intervals. Copyright © 2007 John Wiley & Sons, Ltd.

Field study in a diverse top-management context

Racial differences in promotion candidate performance and reactions to selection procedures: a field study in a diverse top-management context

The present study examined African-American and White promotion candidates' reactions to and performance on selection procedures that were completed within a police department where African Americans occupied the majority of top-management positions. Reactions (perceived job relatedness and test-taking motivation) of 187 candidates competing for promotion to the rank of sergeant were assessed after completing a written job knowledge test and a situational interview. Analyses showed that both the African-American and White candidates judged the situational interview to be more job-related than the pencil-and-paper job knowledge test. In addition, African Americans perceived both selection measures to be more job-related and reported higher levels of test-taking motivation than White candidates even though African Americans performed more poorly than White candidates on the paper-and-pencil test. These results challenge the contention that lower test-taking motivation for African-American candidates is related to racial differences in performance on pencil- and-paper tests. Implications and directions for future research on reactions to selection procedures for promotion in racially diverse employment settings are discussed. Copyright © 2007 John Wiley & Sons, Ltd.

Most of the organic carbon produced in the sunlit upper layer of the ocean is recycled (remineralized) as dead organisms sink to greater depths, but there is considerable uncertainty about how efficient this remineralization process is in the ocean's "twilight zone" (depths between the bottom of the euphotic zone and about 1000 meters). Buesseler et al. (p. 567, see the cover) have used neutrally buoyant sediment traps that can sample sinking particles more faithfully than traps moored in fixed spots that are subject to strong cross-flow from ocean currents. The transfer efficiency of sinking particulate organic matter differed by more than a factor of 2 between the two sites examined; this difference is poorly represented in present biogeochemical models.

Flu triggers heart attacks

Flu triggers heart attacks, study shows (Reuters)

Doses of a flu vaccine lie on a table as San Luis Obispo County public healthcare professionals conduct a mass flu vaccination drill at the Veterans building in San Luis Obispo, California, October 31, 2006. Influenza can trigger deadly heart attacks, researchers said on Wednesday in a study that supports what experts have long believed -- flu can kill people even if they do not die directly from the flu.

Wassat? It's a Wattieza, the world's oldest tree (AFP)

Fossil hunters in the United States have found the world's oldest known tree, a palm-like giant of a species called a Wattieza that lived some 380 million years ago. Their discovery resolves a riddle that has dogged paleo-botanists for 137 years and sheds light on how forests slowly yet powerfully sculpted Earth's landscape, the team report in Thursday's Nature, the weekly British science journal.(Nature)AFP - Fossil hunters in the United States have found the world's oldest known tree, a palm-like giant of a species called a Wattieza that lived some 380 million years ago.

Oldest tree had fronds

Scientist: Oldest tree had fronds, not leaves

CHICAGO, Illinois (Reuters) -- The branches of Earth's oldest tree probably waved in the breeze like a modern palm, scientists said on Wednesday, based on two intact tree fossils that help explain the evolution of forests and their influence on climate.

The 385-million-year-old fossils, which scientists believe are evidence of Earth's earliest forest trees, put to rest speculation about fossilized tree stumps discovered more than a century ago in Gilboa, New York.

Scientists believe these early forests absorbed carbon dioxide, cooling the Earth's surface.

Sparling: Extra dimensions are time-like

Mathematician suggests extra dimensions are time-like

In a recent study, mathematician George Sparling of the University of Pittsburgh examines a fundamental question pondered since the time of Pythagoras, and still vexing scientists today: what is the nature of space and time? After analyzing different perspectives, Sparling offers an alternative idea: space-time may have six dimensions, with the ext

'Smart dust' will one day explore planets

Tiny "smart" devices that can be borne on the wind like dust particles could be carried in space probes to explore other planets, UK engineers say. The devices would consist of a computer chip covered by a plastic sheath that can change shape when a voltage is applied, enabling it to be steered.
