Ground level photosynthetically active radiation dynamics in stands of Acacia mearnsii De Wild.

The objective is to study the dynamics of photosynthetic radiation reaching the soil surface in stands of Acacia mearnsii De Wild and its influence on height growth in stands. This fact gives rise to the formulation of the following hypothesis for this study: "The reduction of the incidence of light inside the stand of black wattle will cause the inflection point in its height growth when this reaches 4 to 5 m in height, i.e.

Environmental scanning: allied health leaders' selection of strategic information.

In environmental scanning, deans and directors of allied health units face the task of making sense of volumes of information from their internal and external environments. A study was conducted to detail the information processing of 108 allied health deans and directors of institutional members of the Association of Schools of Allied Health Professions. The study was a survey that included basic demographic questions and two scenarios, each representing a strategic situation.

Occurrence and detection of iron-deficiency anemia in infants and toddlers.

Infants and toddlers are particularly vulnerable to developing iron deficiency, which can cause irreversible deficits in neurodevelopment. Children at highest risk include premature and low birth weight infants, those who are fed cow's milk rather than breast milk or formula prior to age one, and those who drink large amounts of cow's milk as toddlers. It is important to detect iron deficiency before it becomes frank anemia through the use of appropriate laboratory tests.

Factors that impact clinical laboratory scientists' commitment to their work organizations.

Objective: To assess the predictive ability of various aspects of the work environment for organizational commitment.

Methods: A questionnaire measuring three dimensions of organizational commitment along with five aspects of work environment and 10 demographic and work setting characteristics was sent to a national, convenience sample of clinical laboratory professionals.

Setting And Participants: All persons obtaining the CLS certification by NCA from January 1, 1997 to December 31, 2006.
