Observations of First Occurrence and Severity of Potato Leafhopper, \u3ci\u3eEmpoasca Fabae\u3c/i\u3e (Harris), (Homoptera: Cicadellidae) in the North Central and Eastern United States.

This paper presents available data on the first occurrence dates and the damage severity of the potato leafhopper in the north central and north eastern United States collected during the past 47 years (1951-1997). The data were collected from a variety of sources including: potato leafhopper literature review; published reports; pest alerts; pest surveys; and delphi surveys. First occurrence and severity data show that the arrival time of potato leafhopper and subsequent damage severity varies substantially from year to year. A correlation analysis between date of first occurrence and severity of damage for Michigan, Minnesota, Wisconsin, the north central region and the northeastern region indicated no significant relationship between first arrival dates and damage severity. The lack of a relationship between the time of arrival of the migrant leafhopper and severity indicate that other factors, including frequency and magnitude of arrivals, weather conditions during the growing season and crop management contribute to the eventual severity of damage caused to crops by this migratory pest. The analysis of potato leafhopper severity data showed significant differences between years. There were no significant differences in severity among states within the north central region, indicating that potato leafhopper severity is a regional phenomenon

The Role of Compassion in Medical Ethics and Its Reintegration in Modern Practice

Compassion has been an integral part of medical ethics since its origins, but as medicine progressed, compassion slowly disappeared from practice. The development of any industry results from many complex factors, but the decline of compassion in medicine can be largely attributed to the evolution of technology and role of medical ethics committees. Change is not always negative, but in this case, medicine neglected one of its foundational principles. This is seen by analyzing the history and progression of medical ethics and its four pillars. Plato and Aristotle defined justice in Greek philosophy, Hippocrates used the concept of non-maleficence in his oaths, the philosophy of John Gregory and Kant brought autonomy into a medical context, and the work of Thomas Percival sought to view medicine a beneficent undertaking. These critical principles were summarized by Joseph Fletcher. Each of these individuals also acknowledged the great role compassion played in medical practice. However, as the medical field developed, its reliance on compassion was in part replaced by a thirst for progress and acting ethics committees. Medicine needs compassion because it was built on compassion. It is not simply an ideal drawn from philosophers, it is a necessity for the wellness of both patients and practitioners

Capital and Punishment: Resource Scarcity Increases Endorsement of the Death Penalty

Faced with punishing severe offenders, why do some prefer imprisonment whereas others impose death? Previous research exploring death penalty attitudes has primarily focused on individual and cultural factors. Adopting a functional perspective, we propose that environmental features may also shape our punishment strategies. Individuals are attuned to the availability of resources within their environments. Due to heightened concerns with the costliness of repeated offending, we hypothesize that individuals tend toward elimination-focused punishments during times of perceived scarcity. Using global and United States data sets (studies 1 and 2), we find that indicators of resource scarcity predict the presence of capital punishment. In two experiments (studies 3 and 4), we find that activating concerns about scarcity causes people to increase their endorsement for capital punishment, and this effect is statistically mediated by a reduced willingness to risk repeated offenses. Perceived resource scarcity shapes our punishment preferences, with important policy implications
