Controversies are a potentially powerful teaching tool in the management classroom enabling students to explore different perspectives on an issue and to develop their skills in areas such as critical thinking and communication. Controversy is implicit to learning and to leadership and management roles in workplaces where multiple opposing views inevitably exist. Prior research asserts that constructive controversy resolution skills are important to management students. This multipart study presents a model and measure of controversy teaching approaches and explores evidence of their reliability and validity using confirmatory factor analysis and correlations with relevant outcomes and measures. The three studies, with samples of management and leadership students across several U.S. institutions, provide initial evidence of the validity of the model and measure. Multiple perspectives and avoidance were found to be underlying dimensions of instructors' observed approaches to teaching controversial topics. The controversy teaching approaches model and measure used in this study have potential to support instructional development for management educators, as well as further research on controversy teaching. This study also has practical implications for how instructors approach controversies in the classroom and may aid effective teaching and learning.

In 1821, Percy Shelley argues that "having enslaved the elements, [Man] remains himself a slave," and that our cleverness conceals the "Poetry of life." He asserts that "Poetry" itself can dig humankind out of this mess and imagine free life. Surprisingly, however, he makes no call for more verse. In fact, Shelley does not conceive of "Poetry" as text or credo. Nor does he claim that it can be dormant or dead. I propose that Shelley's late art detaches "Poetry" from the sterile merry-go-round of mystery and demystification, enchantment and disenchantment.

This study examined a model of servant leadership's relationship to organizational commitment through structural and psychological empowerment, focusing on leader–follower dyads in a nonprofit organization. Survey data was collected from 128 employees of a nonprofit organization in a northeastern U.S. city. After model re‐specification, a well‐fitting model emerged, indicating that structural empowerment mediates the relationship between servant leadership and organizational commitment. Moreover, the model suggests that structural empowerment's effect on organizational commitment is both direct and indirect—the latter occurring through the meaning dimension of psychological empowerment. This study provides initial support for structural empowerment being a mechanism through which servant leadership impacts organizational commitment in nonprofits. In addition, the role of meaningful work is highlighted as an antecedent to organizational commitment for nonprofit employees. Servant leaders are suggested to create structurally empowering working environments, which support employees' stronger commitment to the organization.

Aim: To quantify the impact of the 2019–2020 megafires on Australian plant diversity by assessing burnt area across 26,062 species ranges and the effects of fire history on recovery potential. Further, to exemplify a strategic approach to prioritizing plant species affected by fire for recovery actions and conservation planning at a national scale. Location: Australia. Methods: We combine data on geographic range, fire extent, response traits and fire history to assess the proportion of species ranges burnt in both the 2019–2020 fires and the past. Results: Across Australia, suitable habitat for 69% of all plant species was burnt (17,197 species) by the 2019–2020 fires and herbarium specimens confirm the presence of 9,092 of these species across the fire extent since 1950. Burnt ranges include those of 587 plants listed as threatened under national legislation (44% of Australia's threatened plants). A total of 3,998 of the 17,197 fire-affected species are known to resprout after fire, but at least 2,928 must complete their entire life cycle—from germinant to reproducing adult—prior to subsequent fires, as they are killed by fire. Data on previous fires show that, for 257 species, the historical intervals between fire events across their range are likely too short to allow regeneration. For a further 411 species, future fires during recovery will increase extinction risk as current populations are dominated by immature individuals. Main conclusion: Many Australian plant species have strategies to persist under certain fire regimes, and will recover given time, suitable conditions and low exposure to threats. However, short fire intervals both before and after the 2019–2020 fire season pose a serious risk to the recovery of at least 595 species. Persistent knowledge gaps about species fire response and post-fire population persistence threaten the effective long-term management of Australian vegetation in an increasingly pyric world.
