All of these observations taken together suggest that breast cancer progression may be more complex than the current linear theory of activation and inactivation of oncogenes and tumor suppressor genes, respectively, and may be dependent upon such contingencies as quantitative levels and timing of gene expression.
The timing of the quantitative and qualitative strands: The timing of the two strands will be concurrent, i.e., both methods will be employed in a single phase.
A quantitative analysis of the rate and timing of population growth in T. b. mexicana can help us understand the response of wildlife species to major innovations in human cultural evolution such as the development of agriculture.
Previous studies have suggested that the levels of Wnt ligand or downstream effects are graded in mouse and zebrafish (Aulehla and Pourquié, 2010; Aulehla et al., 2003; Aulehla et al., 2008; Row and Kimelman, 2009; Thorpe et al., 2005), but quantitative analysis of the distribution and timing of Wnt activity is still lacking.
The inclusion of numeracy as a key component of health literacy has been driven by claims that high percentages of the population lack the quantitative skills to understand dates and timing of medication dosages, information on appointment slips and financial information associated with healthcare [ 25].
Quantitative models describing gene expression in terms of quantity, speed and timing in different environmental contexts are essential for the study of many biological processes.
Comparability of interventions, outcomes and timing of assessments, and risk of bias were considered to determine potential for appropriate quantitative synthesis of the trials.
The rate and timing of this deformation, as well as the magnitude of the uplift-induced erosion processes, still lack a quantitative validation.
Mixed methods study with a convergent parallel design that occurs when the researcher uses concurrent timing to implement the quantitative and qualitative strands during the same phase of the research process, prioritizes the methods equally and keeps the strands independent during the analysis [ 22].
Since the mistiming-model fails to account for all empirical findings, we propose to add another quantitative dimension besides timing and call the resulting model goalkeeper-model.
