In general, with some noted exceptions, Mechner's contentions regarding evolutionary history remind me of an evolutionary psychological approach that I have questioned on several occasions (e.g., Schlinger, 1996, 2004), pointing out that they are "just-so stories" created after the fact to account for complex behavioral relations that can be more parsimoniously explained by operant and respondent contingencies.
This fact creates a challenging condition due to the difficult diagnosis because physicians are trained to diagnose parsimoniously, and multiple infections of the same anatomical site can simulate a single infection due to the similarity of the symptoms among them [14, 15].
The proposed model seems to highlight more directly and parsimoniously the differences between two and more cohorts.
NGC 358 parsimoniously resolves into a 2' trapezoid of four stars, magnitudes 11.0 to 12.7.
Sixteen of these polymorphisms were singleton mutations with two variants and 32 were parsimoniously informative with two variants.
This merits intensive scientific effort for novel drug development in neuropsychiatric disorder that may parsimoniously rectify co-occurring GLU-related diseases of the brain, body, and mind.
The first one, Identity in Family Firms: A Theoretical Analysis of Incentives and Contracts, by Marcelo Sanches Pagliarussi and Cristiano Costa, presents a principal-agent model that coherently and parsimoniously explains previous findings from research on executive compensation in family firms.
While the House rations time parsimoniously, often to a single hour of debate even on major legislation, the Senate insists on giving all its members the widest possible latitude to hold a question up to every light.
Among the 700 bp of the partial mtDNA control region (Cyt b-CR) gene, only 32 (4.5%) sites were variables with 6 singleton sites, leaving 26 (3.7%) potentially parsimoniously informative characters, indicating that this gene is a reliable marker to infer genetic variations at the population level and 668 (95.5%) sites were conserved.
The basis for de-trending includes: (i) yields have trended up with technological advancement, (ii) trend explains a large portion of the overall variance, de-trending therefore will ensure that the [R.sup.2] only measures the effect of weather variables, and (iii) a log standardization correctly and parsimoniously accounts for relationship between yield and both the mean and variance of the trend variable.
Reference-based phylogenetic analysis identified [approximately equals] 117,000 shared SNPs, of which [approximately equals] 60% were parsimoniously informative (Figure).
In a world with limited renewable resources and a severely threatened natural environment, we should be critical of optimism about success in 'ending poverty in all its forms' that afflicts the majority of the world's people, while continuing to define poverty parsimoniously, and promoting excessively high incomes for a small proportion of people whose consumption patterns adversely impact on human security, climate change and environmental degradation.
