Morphological Awareness: An Avenue For Improving Vocabulary, Word Recognition, Spelling And Reading Comprehension, Chenell Loudermill

Science of Reading

Learning requires the integration of many skills, with language development being a crucial foundational aspect. Language development across five domains-phonology (the sounds within a language), morphology (word structure/formation), semantics (word meaning), syntax (sentence structure/grammar), and pragmatics (use in varying contexts)-unequivocally supports the acquisition of reading and writing skills. Specifically, morphological knowledge is vital for improving vocabulary, word recognition, spelling and reading comprehension. This practice brief provides an overview of morphological awareness and derived words, provides a rationale for teaching morphological awareness, and instructional strategies supported by science.

Aha And Hmm: The Joy Of Writing Senryu, John J. Han

KAUPA Letters

Senryu, a satiric and often humorous counterpart to haiku, emerged in mid-18th century Japan as a form of popular self-expression among the rising merchant class. Named after the poet and editor Karai Senryu, this genre focuses on human nature, social behavior, and everyday life rather than the seasonal themes central to haiku. Traditionally composed in a 5-7-5 syllabic structure, modern English-language senryu are often written in free style with fewer than 17 syllables. While frequently humorous, senryu can also capture serious aspects of human experience, including hardship and social issues. Unlike haiku, which encourages contemplation, senryu aims to evoke immediate …

Additionality Of Solar Tax Incentives Under Community Choice Aggregation In Ohio, Michael L. Smith, Carson Reeling, Michael D. Wilcox

Department of Agricultural Economics Faculty Publications

In the State of Ohio, the electric regulatory landscape permits local governments to become energy suppliers to residents and small businesses through community choice aggregation (CCA). Some CCAs provide enrollees 100% renewable electricity. Concurrently, the federal government offers an income tax credit (ITC) for the purchase of a solar array. With policy incentives, it is important to ensure they encourage behavior beyond the baseline scenario without the ITC. This is known as “additionality.” Renewable aggregation programs may crowd out the benefits of the ITC, violating additionality. This paper assesses additionality of the ITC in the context of Ohio’s CCA programs. …

Economic Analysis Of Global And Local Policies For Respecting Planetary Boundaries, Thomas Hertel

Department of Agricultural Economics Faculty Publications

In a series of highly cited papers over the period of 2009–2023, earth system scientists have identified a set of nine planetary boundaries that must not be breached if we wish to avoid catastrophic consequences for nature and humanity. These range from well-mixed, global boundaries, such as climate-altering atmospheric greenhouse gas concentrations, to localized limits on freshwater availability and reactive nitrogen entering the environment. Recent estimates suggest that six of the nine planetary boundaries have already been breached. The food system is a key driver of these exceedances and, therefore, must play a key role in any solutions. However, the …
