Welcome to Volume 24, No. 4 of Enterprise and Society. There is a slight deviation from tradition for this issue this year. As is well-known, the final issue of the year typically carries both the Presidential Address, delivered at the annual meeting in the spring, as well as summaries by all Krooss Prize finalists. Those of you able to attend the annual meeting in Detroit in March 2023 will have been spellbound by Dan Wadhwani’s Presidential Address, which wove together strands of his rich historical entrepreneurship scholarship with threads of his own fascinating family story. Converting such a personal address, combined with the continuous uncovering of materials, has involved intricate ongoing work. Dan and I have agreed to hold his address back to give him the opportunity to write the piece he really wants to write. Personally, I cannot wait to read it.

This article argues that the purpose of ravaging in Greek warfare was not to goad the enemy into fighting or to cause systematic economic harm but to facilitate plundering. The cereal harvest was commonly chosen as a time for invasion, because it maximized the amount of plunder an invading force could expect to find in the enemy countryside. While ravagers were unlikely to cause permanent economic harm to a community as a whole, they could imperil the livelihoods of individual farmers, both directly through theft and destruction and indirectly by preventing farmers from processing the harvest in a timely fashion. This explains the consistent fear of plundering and ravaging present in our sources.

This article sheds light on the factors that pave the way from voter abstention to voter turnout based on extensive research of tweets on national and local elections in Turkey. We find that the negative campaign strategy of the incumbent and the fact that the campaigning process has taken place on a very uneven playing field have triggered a set of emotions, primarily moral outrage and anger among the electorate, which have the power to change voting patterns in a significant way. The effect of negative campaigning on expressive voting was further enhanced by the pulling effect of the candidates and their public supporters and endorsements. We found that other, competing explanations of political outcomes are secondary to the mechanisms above.

Many formerly incarcerated people have civil legal needs that can imperil their successful re-entry to society and, consequently, their health. We categorize these needs and assess their association with cardiovascular disease risk factors in a sample of recently released people. We find that having legal needs related to debt, public benefits, housing, or healthcare access is associated with psychosocial stress, but not uncontrolled high blood pressure or high cholesterol, in the first three months after release.

This note identifies a new acrostic in Christodorus’ sixth century c.e. Ekphrasis of the Baths of Zeuxippus (Anth. Pal. 2) and explains its significance.

We study ordered groups in the context of both algebra and computability. Ordered groups are groups that admit a linear order that is compatible with the group operation. We explore some properties of ordered groups and discuss some related topics. We prove results about the semidirect product in relation to orderability and computability. In particular, we give a criteria for when a semidirect product of orderable groups is orderable and for when a semidirect product is computably categorical. We also give an example of a semidirect product that has the halting set coded into its multiplication structure but it is possible to construct a computable presentation of this semidirect product.

We examine a family of orderable groups that admit exactly countably many orders and show that their space of orders has arbitrary finite Cantor–Bendixson rank. Furthermore, this family of groups is also shown to be computably categorical, which in particular will allow us to conclude that any computable presentation of the groups does not admit any noncomputable orders. Lastly, we construct an example of an orderable computable group with no computable Archimedean orders but at least one computable non-Archimedean order.

As a relatively active region, ephemeral region (ER) exhibits highly complex pattern of magnetic flux emergence. We aim to study detailed secondary flux emergences (SFEs) which we define as bipoles that their locations close to ERs and finally coalesce with ERs after a period. We study the SFEs during the whole process from emergence to decay of 5 ERs observed by the Helioseismic and Magnetic Imager (HMI) aboard Solar Dynamics Observatory (SDO). We find that the maximum unsigned magnetic flux for each of the ERs is around 1020 Mx. All ERs have tens of SFEs with an average emerging magnetic flux of approximately 5×1018 Mx. The frequency of normalized magnetic flux for all the SFEs follows a power law distribution with an index of -2.08. The majority of SFEs occur between the positive and negative polarities of ER, and their growth time is concentrated within one hour. The magnetic axis of SFEs also exhibits a random characteristic. We suggest that the relationship between SFEs and ERs can be understood by regarding the photospheric magnetic field observations as cross-sections of an emerging magnetic structure. Tracking the ERs’ evolution, we propose that the flux emergences are partially emerged Ω-loops, and that the SFEs in ERs may be sequent emergences from the bundle of flux tube of ERs.
