AbstractGrape hyacinth is a perennial bulbous species in the Liliaceae. It is commonly grown as an ornamental plant, but it can spread into agricultural fields and become weedy, potentially interfering with harvest and fall-planted crops. There has been limited research on controlling grape hyacinth in cropping systems. Fall and spring applied field-research studies were conducted to determine grape hyacinth control with herbicides labeled for use in wheat or winter fallow before planting soybean. Among fall-applied herbicides, paraquat resulted in the greatest initial grape hyacinth control (90% to 100%). Grape hyacinth control, 16 months after application (MAA), was variable, but the top-performing treatments were glyphosate and metsulfuron plus paraquat, resulting in 65% and 50% control, respectively. After spring applications, grape hyacinth control in November (7 MAA) was variable, but top-performing treatments were glyphosate and metsulfuron, which resulted in at least 26% control. Spring-applied paraquat, carfentrazone, metsulfuron, and sulfosulfuron resulted in 73%, 68%, 69%, and 60% reductions in grape hyacinth bulb counts, compared with the nontreated control 7 MAA, and were the top-performing treatments. Despite product-label prohibitions on rotation to soybeans, no soybean yield reductions were observed from any treatment in either study. Single applications of certain herbicides in the fall or spring can result in good control (>80%) of grape hyacinth initially, but long-term control is poor, and additional research is required.

Lew Margolis’s commentary on our discussion of field dilemmas delineates the basic tenets of research ethics and presents the historical backdrop for Institutional Review Board governance of the conduct of scientific research. Margolis’s commentary also highlights two important points: (1) within broad boundaries, multiple strategies may exist for resolving ethical dilemmas, and (2) field judgments about the best strategy for resolving ethical dilemmas may sometimes appear less than optimal with hindsight. These emphases reinforce the critical need for continued dialogue about the practical application of research ethics in applied field settings. We further emphasize the importance of conducting this dialogue not only in community forums but in academic arenas. The professional expertise of field researchers often is derived from direct experience with or membership in the communities being studied. For academic discussion of research ethics to have real-life utility, it is essential that conceptual discussion be translated into discussion of these issues as they apply to real-life situations demanding real-life solutions. We invite others to continue this dialogue about the practical application of research ethics to dilemmas that have been encountered during the conduct of applied field research.

In June, 1988 I arrived in Senegal to begin my doctoral field research as a member of an interdisciplinary team of social scientists from the U.S., Senegal, and France. At the invitation of the Senegalese government, I was to undertake a multi—year research initiative assessing the projected environmental and economic impacts resulting from cessation of the natural flood on the Senegal River. The main objective of the study was to understand how the impoundment of the Senegal River would affect the socioecological and political economic dimensions of production in the middle valley. It was also to document the responses of farmers, herders, and fishers to changing conditions of the river's hydrology and flooding. The river had been drastically altered in recent years by the construction of two dams, a high dam at Manantali, Mali completed in 1987, and a salt intrusion dam at Diama, Senegal, completed in 1986.

Abstrak. Tujuan dari penulisan artikel ini adalah untuk memunculkan sebuah ide atau gagasan baru yang berupa sebuah metode dengan sebutan sistem paket murni. Metode ini metode muncul dengan latar belakang adanya beberapa persoalan yang terjadi pada penyelenggaraan  pemilu serentak tahun 2019 lalu, salah satu penyebab persoalan itu adalah banyaknya jumlah penggunaan 5 (lima) kertas suara yang dicoblos berdampak pada banyak hal. Melalui penggunaan metode penelitian lapangan yang diterapkan, harapanya akan diperoleh sebuah data yang valid dengan tujuan untuk suatu temuan, pembuktian, dan pengembangan pengetahuan sehingga ke depannya akan bisa dipergunakan dalam melakukan pemecahan serta sebagai salah satu solusi untuk menyelesaikan sebuah permasalahan di lapangan. Hasil yang berupa ide atau gagasan dengan nama sistem paket murni ini nantinya bisa menjadi sebuah masukkan dalam merancang suatu kebijakan terkait tata cara pelaksanaan pemilu serentak yang akan diselenggarakan diwaktu yang akan datang untuk meminimalisir resiko persoalan yang akan terjadi dan mewujudkan efisiensi biaya logistik penyelenggaraan pemilu serentak. Abstract. The purpose of writing this article is to bring up a new idea or idea in the form of a method called a pure package system. This method emerged against the background of several problems that occurred in the holding of the simultaneous general election in 2019, one of the causes of the problem was the large number of uses of the 5 (five) ballot papers that were punched which had an impact on many things. Through the use of applied field research methods, it is hoped that valid data will be obtained with the aim of finding, proving, and developing knowledge so that in the future it can be used in solving problems and as a solution to solve a problem in the field. The results in the form of ideas or ideas with the name of a pure package system can later become an input in designing a policy related to the procedures for holding simultaneous elections to be held in the future to minimize the risk of problems that will occur and realize logistics cost efficiency in holding simultaneous elections.
