Historical Biogeography: An Introduction

Although biogeography should be easily defined--the research of the geographic distributions of organisms--the topic itself is awfully advanced, regarding quite a number clinical disciplines and a bewildering range of ways. For comfort, biogeographers have well-known study traditions: ecological biogeography and old biogeography.

Philosophy of Science: Volume 2, From Explanation to Justification (Science and Technology Studies)

Initially released as medical examine, this pair of volumes constitutes a basic treatise at the technique of technology. Mario Bunge, one of many significant figures of the century within the improvement of a systematic epistemology, describes and analyzes medical philosophy, in addition to discloses its philosophical presuppositions.

Some Gronwall Type Inequalities and Applications

Gronwall sort necessary inequalities of 1 variable for genuine services play a vital position within the Qualitative idea of Differential Equations. the most objective of the current learn monograph is to provide a few ordinary purposes of Gronwall inequalities with non-linear kernels of Lipschitz form of the issues of boundedness and convergence to 0 at infinity of the recommendations of yes Volterra critical equations.

Origin and Evolution of Earth: Research Questions for a Changing Planet

Questions about the beginning and nature of Earth and the existence on it have lengthy preoccupied human suggestion and the clinical recreation. interpreting the planet's background and approaches might increase the facility to foretell catastrophes like earthquakes and volcanic eruptions, to regulate Earth's assets, and to count on adjustments in weather and geologic tactics.

Reduced reliability in turn reduces construct validity; that is, validity is called into question when a measure cannot consistently capture the construct it is intended to measure. Measurement bias is another potential problem with missing data under mono-operations. , mono-operations bias). For example, if an index of socioeconomic status includes income, education, and occupation, and one or more of these indicators are missing, the construct is incomplete. The problem is compounded if the missing information is also the most critical component of the construct.

When a study group includes more participants with such characteristics than another group, the result may be more dropouts. The consequences of such differences are usually detrimental to the validity of study results. First, the final sample forms a subgroup that risks poorly representing the target population. Second, groups may have different attributes that serve as confounds, and thereby threaten the internal validity of the study. That is, differences in the outcomes demonstrated among the groups at posttest cannot be claimed, with confidence, to be caused only by the intervention, because they may be associated with these other factors.

30 MISSING DATA Participant Attrition Studies that involve multiple measures over time present many problems for researchers, especially when data are missing for some of those measurement occasions. Retention of participants in longitudinal studies may fail for varied reasons, and the failure to capture all data for all occasions presents serious threats to internal validity. When attrition or mortality affects treatment groups, the ability to attribute outcomes to the intervention is seriously jeopardized.
