Machine learning models are powerful tools which may aid in the prediction of survival outcomes of cancer patients. This study evaluated eight classification models and eight regression models on their ability to predict survival outcomes on breast cancer and prostate cancer data sets from the SEER database. The most accurate...
The release of transgenes into the environment by transgenic plant species is a significant ecological concern, and consequently a containment method for these genetically modified organisms is highly sought after. For poplar trees, an option for containment is to produce trees that do not flower and therefore cannot spread genetic...

Soil food webs process the majority of terrestrial carbon, and influence overall ecosystem function. A primary distinction among soil food webs is based on fungal versus bacterial pathways of decomposition; these lead to fundamentally different soil function, and are expected to differ in dominance between meadows and forests. This assumption...
Objective: Alcohol and cannabis use and co-use among college students is prevalent in the United States (Bravo et al., 2021). These substances have been linked to poor collegiate academic performance in past research.

The purpose of this study was to investigate the memory factors
associated with preschoolers' performance in a two-choice, uncertain
outcome decision situation. Choice behavior was examined under
two conditions: one, (NMA), in which the child was required to
rely on his memory to establish an appropriate prediction of the
occurrence...
The purpose of this study was to investigate some of the
factors from childhood experience which might contribute to the kind
of church attendance practices which individuals adopt as adults.
The factors chosen for investigation were enforced church attendance
in childhood, parental church attendance practices, the kind of discipline
employed...
The purpose of this investigation was to duplicate the methodology
of the Pitcher and Prelinger (1963) study, using their theoretical framework
and category system, to examine the cultural impact upon the
development of a group of socioeconomically disadvantaged preschool
children as reflected in their fantasy products, specifically
in their spontaneously...
The purpose of this study was twofold: first, to examine the
choice of living setting of university sophomore women in relation to
their value preferences and in relation to selected settings, socioeconomic
background, and circumstance factors surrounding their
choices. The secondary aim of the study was to investigate how the...
The purpose of this study was to test Siegel's utility model of
choice behavior under conditions of verbal reinforcement, in a nursery
school population of both sexes. Two major hypotheses were
tested: The ordinal hypothesis stated that under conditions of increased
value of the payoff subjects' stable-state strategies will
occur...
