Abstract A preventative insecticide treatment is a tactic compatible with an integrated pest management (IPM) strategy for a particular pest only when a rescue treatment is not a realistic option, and if there is a reasonable expectation of economic damage by that pest. Most corn, Zea mays L., planted in the United States is protected from several sporadic early-season insect pests by neonicotinoid seed treatments, usually without the knowledge of the threat posed in a given field. We undertook an extensive literature review of these sporadic pests to clarify the prevalence of economic infestations in different regions of the United States, and the agronomic, biotic, and abiotic factors that affect the likelihood of attack. The summaries of the prevalence and risk factors presented here should help farmers and consultants better assess the value of preventative protection of seedling corn under local conditions, and provide others with a better understanding of the complexities farmers face in assessing risks posed by potential pests. The profiles suggest that, in general, pressure from most sporadic pests on seedling corn is rare or local, seldom high enough to decrease yield. However, this is not true in all regions for all sporadic pests. An important issue exposed by the profiles is that the value of preventative insecticide protection of seedling corn depends on understanding the likely combined pressure from multiple species. While such risk may often still be negligible, there is a great need for robust methodology to assess the risk posed by multiple pests. This represents a significant challenge for future research.

Abstract The article describes the idea of creation and development of Polish biweekly magazine “Biały Orzeł” (“White Eagle”), originated in Boston in 2002/2003 by the White Eagle Media LLC publishing house. The periodical, which has been published until today, was at the time one of the largest projects in the segment of so-called ethnic media in the United States. The work’s aim is to present the title’s history, identify factors affecting on creation of the Polish diaspora press, diagnose components determining the success/failure of the project, as well as local conditions that had a direct impact on decision to launch described press title. The methodology used in the implementation of this material includes in-depth interviews with project co-founders (publishers and journalists) carried out over 2017 and 2018, executed jointly on a group of 9 people, providing quality data from staff directly involved in described publishing project from its very beginnings. A valuable source of data was also open access to archives of the “White Eagle” hard copies, dated between 2003 and 2008.

Factors Affecting

Climate change and invasive species are major environmental issues facing the world today. They represent the major threats for various types of ecosystems worldwide, mainly managed ecosystems such as agriculture. This study aims to examine the link between climate change and the biological invasion of insect pest species. Increased international trade systems and human mobility have led to increasing introduction rates of invasive insects while climate change could decrease barriers for their establishment and distribution. To mitigate environmental and economic damage it is important to understand the biotic and abiotic factors affecting the process of invasion (transport, introduction, establishment, and dispersal) in terms of climate change. We highlight the major biotic factors affecting the biological invasion process: diet breadth, phenological plasticity, and lifecycle strategies. Finally, we present alien insect pest invasion management that includes prevention, eradication, and assessment of the biological invasion in the form of modelling prediction tools.

The effect of foreign policy on terrorism is an important area of research that bridges work on international relations and intrastate conflict by highlighting how an outside country can influence attacks from a nonstate actor in another country. Research in this area is important for understanding how countries like the United States can best deal with the threat of international terrorism. Research has generally demonstrated that states with active foreign policies are more likely to experience international terrorism, particularly democracies and the United States. This has been hypothesized to occur because active foreign policies create blowback, or negative feelings toward a state, leading to greater acts of terrorism against that state. Beyond the effects of a state’s general foreign policy, others have looked at more specific policies, such as military occupation and intervention. This body of research argues that international terrorism is often a response to perceived occupation of an area. Groups see terrorism as a method to dislodge the occupying force. This argument has been refined by other scholars, who have presented conditions or extensions of this argument. Others have focused on military intervention, arguing that the presence of troops, the negative sentiment that they evoke, and their effect on strengthening the government all create incentives for groups to attack the foreign power that has deployed troops. Foreign aid has been seen as a policy that can address the threat of terrorism. Aid has been argued to be able to improve local conditions and incentivize and reward local states for engaging in counterterrorism. Others have presented conditions under which aid is more or less likely to be effective, including the idea that military aid might actually increase the amount of terrorism, for reasons similar to military intervention, and create an incentive for states to maintain a terrorist threat. Other foreign policy approaches have focused on legal attempts to stop terrorists from financing their organizations. These policies have been driven by the United Nations, coalitions of states, and individual states. This article also focuses on the methodological issues that all these studies face, as well as future research directions.

The increasing demand for multifamily housing in the United States requires alternatives for building more affordable and sustainable housing to improve the quality of life for millions of families. Offsite construction (OSC) strategies may be a viable alternative for tackling this problem. Although the use of OSC is significant in the multifamily housing market in the world and it is also very promising in the US, a scarce amount of literature has focused on this topic. The purpose of this study is to identify specific factors that affect decisions on the use of OSC in multifamily housing in the US. Focusing on the sustainability dimensions of construction—social, environmental, and economic—the authors reviewed literature that was published between 2000 and 2019 and identified factors that are related to OSC adoption in general construction, in housing construction, and, more specifically, in multifamily housing construction in the US. Subsequently, a discussion on some important factors affecting decisions on the use of OSC in the American multifamily market is provided. The discussion focused on factors that, although important, have been under explored in the literature that addresses the use of OSC in multifamily projects, especially in the US, which are: customer’s attitude, building performance, and building comfort and indoor environmental quality (IEQ). In addition, a brief discussion regarding the importance of design to the uptake of OSC in multifamily projects is provided. This is one of the first studies dedicated to exploring the social, environmental, and economic factors that affect the use of OSC in multifamily housing in the US. The study also identifies research gaps, which serve as a roadmap for future research.

The cover photograph for this issue of Public Voices was taken sometime in the summer of 1929 (probably June) somewhere in Sunflower County, Mississippi. Very probably the photo was taken in Indianola but, perhaps, it was Ruleville. It is one of three such photos, one of which does have the annotation on the reverse “Ruleville Midwives Club 1929.” The young woman wearing a tie in this and in one of the other photos was Ann Reid Brown, R.N., then a single woman having only arrived in the United States from Scotland a few years before, in 1923. Full disclosure: This commentary on the photo combines professional research interests in public administration and public policy with personal interests—family interests—for that young nurse later married and became the author’s mother. From the scholarly perspective, such photographs have been seen as “instrumental in establishing midwives’ credentials and cultural identity at a key transitional moment in the history of the midwife and of public health” (Keith, Brennan, & Reynolds 2012). There is also deep irony if we see these photographs as being a fragment of the American dream, of a recent immigrant’s hope for and success at achieving that dream; but that fragment of the vision is understood quite differently when we see that she began a hopeful career working with a Black population forcibly segregated by law under the incongruously named “separate but equal” legal doctrine. That doctrine, derived from the United States Supreme Court’s 1896 decision, Plessy v. Ferguson, would remain the foundation for legally enforced segregation throughout the South for another quarter century. The options open to the young, white, immigrant nurse were almost entirely closed off for the population with which she then worked. The remaining parts of this overview are meant to provide the following: (1) some biographical information on the nurse; (2) a description, in so far as we know it, of why she was in Mississippi; and (3) some indication of areas for future research on this and related topics.

We have investigated the differences in support for the U.S. Supreme Court among black, Hispanic, and white Americans, catalogued the variation in African Americans’ group attachments and experiences with legal authorities, and examined how those latter two factors shape individuals’ support for the U.S. Supreme Court, that Court’s decisions, and for their local legal system. We take this opportunity to weave our findings together, taking stock of what we have learned from our analyses and what seem like fruitful paths for future research. In the process, we revisit Positivity Theory. We present a modified version of the theory that we hope will guide future inquiry on public support for courts, both in the United States and abroad.
