Designation of a Neotype for Mitchell’s Satyr, \u3ci\u3eNeonympha Mitchellii\u3c/i\u3e (Lepidoptera: Nymphalidae)

(excerpt) The Mitchell’s satyr, Neonympha mitchellii French 1889 (Lepidoptera: Nymphalidae) was described as a new species based on a series of six males and four females collected by J. N. Mitchell from “Wakelee bog” in Cass County, Michigan (French 1889). French did not designate a holotype from this series

Changes in Families’ Organic Food Consumption

According to recent research based on the theoretical concept of the family cycle it can be assumed that expenditures for organic food in families decline as children get older. For organic food marketing this raises the question to which extent organic food consumption in families is characterised by changes, when changes in families’ organic food consumption appear over time and what the reasons for these changes are. The article presents theoretical background, research design and results of a qualitative study. Based on qualitative interviews which were analysed according to Grounded Theory it is found that consumers perceive changes in organic food consumption in terms of increase and decrease. As causal conditions for this, pregnancy, the feeding of babies with complementary food, children’s adolescence, a new partner and a new situation in household income could be identified. The results point out how qualitative research can contribute to the completion of existing and the inspiration for future quantitative studies.Family Cycle, Organic Food, Qualitative Interviews, Food Consumption/Nutrition/Food Safety,

Nonequilibrium plasmons with gain in graphene

Graphene supports strongly confined transverse-magnetic sheet plasmons whose spectral characteristics depend on the energetic distribution of Dirac particles. The question arises whether plasmons can become amplified when graphene is pumped into a state of inversion. In establishing a theory for the dynamic non-equilibrium polarizability, we are able to determine the exact complex-frequency plasmon dispersion of photo-inverted graphene and study the impact of doping, collision loss, and temperature on the plasmon gain. We calculate the spontaneous emission spectra and carrier recombination rates self-consistently and compare the results with approximations based on Fermi's golden rule. Our results show that amplification of plasmons is possible under realistic conditions but inevitably competes with ultrafast spontaneous emission, which for intrinsic graphene, is a factor 5 faster than previously estimated. This work casts new light on the nature of non-equilibrium plasmons and may aid the experimental realization of active plasmonic devices based on graphene.Comment: 17 pages, 7 figures, published in PR

Addicts Speak: An Exploratory Ethnographic Study of Opioid Addiction

This thesis explores the experiences of people in recovery from opioid addiction in order to better understand the many process of recovery. Employing both participant observation and focused life history interview, and utilizing a grounded theory approach to data analysis, this research emphasizes data-driven conclusions. The research provides numerous insights into the process of recovery from opioid addiction, as well as factors that help to facilitate and sustain the process, the role that services play, and how services can be developed to better meet the needs of those in recovery

Understanding Public Trust in the Courts: The Centrality of Vulnerability

Courts have an important place in American life. While many would think first of the police as the institution most directly responsible for maintaining the law, the courts are an integral part of ensuring social order. Indeed, as illustrated by practices regarding warrants and cases challenging police action, much of the authority typically attributed to the police is, to some degree, controlled by the courts. Importantly, however, as is often the case with institutions of government in the United States, this considerable authority comes with relatively limited power: The judiciary controls “neither the purse nor the sword,” leaving it heavily reliant upon other institutions and upon the public in general.1 Thus, an extreme argument can be made that the courts need the positive perceptions of the majority of the public to function at all,2 but others have pointed to these perceptions as important simply because effective courts should be perceived well by the public they serve.3 In either case, there is little question that public perceptions of the courts matter and in recognition of this, considerable effort has been expended by to improve and protect them.

Akzeptanz von nachhaltiger Aquakultur: Treffen die Produktinformationen die Wünsche von Öko-Käufern?

Aquaculture is becoming more important for human consumption. Sustainable aquaculture procedures came up as an alternative, due to the negative environmental impacts of conventional aquaculture procedures. Nonetheless, little is known about consumer segments for sustainable aquaculture and their preferences. Overall, participants paid a lot of attention on the declaration of origin; specifically fish products from Germany or Denmark were preferred along with local products. Consumers are generally supporting a sustainable production. However, communication claims and labelling schemes should be improved to reach consumer acceptance
