The phrase "at a concrete level" is correct and usable in written English.
It can be used when discussing specific, tangible aspects of a topic or issue, as opposed to abstract or theoretical considerations.
Example: "To understand the impact of climate change, we need to examine it at a concrete level, focusing on local weather patterns and their effects on agriculture."
Alternatives: "on a practical level" or "in tangible terms".
The data were kept at a concrete level, as far as possible, in order to minimize the effects of pre-understanding on the analysis.
When taken in conjunction with the previous literature, it seems sensible to suggest, therefore, that the role played by the pIFG during reasoning is most likely to facilitate attention to the task at a concrete level, with the abstract rules and higher-level relationships that form the overarching task schema being preferentially processed in more dorsal/anterior frontal lobe subregions.
Schmeichel and Vohs (2009) demonstrated that affirming the self at an abstract level (writing why one pursues a particular personal value) resulted in more delay of gratification on a computer game than affirming the self at a concrete level (writing how one pursues personal values), and counteracted depletion of self-regulatory resources by prior engagement in a self-control task.
At the same time, there is a rich discussion, proceeding at a more concrete level than what is characteristic of philosophical thought, to be found among judicial opinions and legal analyses examining particular systems of law.
Such an interactive constitution of the common will means that for Hegel that the identity among wills is achieved because of not in spite of co-existing differences between the particular wills of the subjects involved: while contracting individuals both will the same exchange, at a more concrete level, they do so with different ends in mind.
Taken together, these findings converge on the hypothesis that while the pIFG controls attention and behavior at a relatively concrete level, more dorsal and anterior frontal lobe subregions support the higher-level rules and relationships that make up the overarching task schema.
Thinking about healthy eating can take place at a concrete representation level (e.g. "an apple contains vitamins"), but also at an abstract representation level (e.g. "it depends how much you eat").
A suite of operational semantics based on the notion of bisimulation is introduced both at the concrete level (instances) and at the abstract level (schemata), giving rise to a semantic framework that benefits from the cross-fertilization of tools originally designed in quite different research areas (databases, concurrency, logics, static analysis).
At the concrete level, the impact of three optimised paste mixtures on SCC properties was assessed.
Abstract models may admit spurious counterexamples (false negative results) which are executions at the abstract level with no corresponding executions at the concrete level.
The loading applied at the concrete level, is first concentrated ("downscaled") to maximum stresses related to cement paste volumes which are directly adjacent to the aggregates, i.e. to the interfacial transition zones (ITZ).
