Parasitism of \u3ci\u3ePlathypena Scabra\u3c/i\u3e (Lepidoptera: Noctuidae) by \u3ci\u3eSinophorus Teratis\u3c/i\u3e (Hymenoptera: Ichneumonidae)

(excerpt) A study was conducted at the Ecology Research Center, Miami University, Butler County, Ohio, during the summer of 1990 to examine the effects of strip intercropping sorghum and soybean on the occurrence of parasitoids and incidence of disease in larvae ofthe green cloverworm, Plathypena scabra (F.) (Lepidoptera: Noctuidae), a sporadic pest of soybeans. The details of the experimental design and results are reported elsewhere (Williams et al. 1995)

Alfred Russel Wallace Notes 11: Wallace, Darwin, Education, & the Class Question

In a recent paper by John van Wyhe (2020), the issue of class was discussed and whether Wallace came from a “working class” background. As a result of class differences could or should Wallace be considered differently from Darwin, who supposedly came from a higher class? An additional “myth” highlighted was whether Wallace left school, aged 14, due to difficult family financial circumstances. Van Wyhe contends that Darwin and Wallace were both middle class, and Wallace left school at the “normal” school-leaving age. This article shows that both contentions are mistaken. Class in the 19th century was complex and difficult, indeed a developing concept. The idea of a “middle class” was new and within this there was a stratification between the upper and lower middle classes. As for schools and education, there was no set leaving age specified and education was usually determined by class and family finance

Algorithms for geodesics

Algorithms for the computation of geodesics on an ellipsoid of revolution are given. These provide accurate, robust, and fast solutions to the direct and inverse geodesic problems and they allow differential and integral properties of geodesics to be computed.Comment: LaTex, 12 pages, 8 figures.

Public health economics: a systematic review of guidance for the economic evaluation of public health interventions and discussion of key methodological issues

BACKGROUND: If Public Health is the science and art of how society collectively aims to improve health, and reduce inequalities in health, then Public Health Economics is the science and art of supporting decision making as to how society can use its available resources to best meet these objectives and minimise opportunity cost. A systematic review of published guidance for the economic evaluation of public health interventions within this broad public policy paradigm was conducted. METHODS: Electronic databases and organisation websites were searched using a 22 year time horizon (1990–2012). References of papers were hand searched for additional papers for inclusion. Government reports or peer-reviewed published papers were included if they; referred to the methods of economic evaluation of public health interventions, identified key challenges of conducting economic evaluations of public health interventions or made recommendations for conducting economic evaluations of public health interventions. Guidance was divided into three categories UK guidance, international guidance and observations or guidance provided by individual commentators in the field of public health economics. An assessment of the theoretical frameworks underpinning the guidance was made and served as a rationale for categorising the papers. RESULTS: We identified 5 international guidance documents, 7 UK guidance documents and 4 documents by individual commentators. The papers reviewed identify the main methodological challenges that face analysts when conducting such evaluations. There is a consensus within the guidance that wider social and environmental costs and benefits should be looked at due to the complex nature of public health. This was reflected in the theoretical underpinning as the majority of guidance was categorised as extra-welfarist. CONCLUSIONS: In this novel review we argue that health economics may have come full circle from its roots in broad public policy economics. We may find it useful to think in this broader paradigm with respect to public health economics. We offer a 12 point checklist to support government, NHS commissioners and individual health economists in their consideration of economic evaluation methodology with respect to the additional challenges of applying health economics to public health

Clone Size of \u3ci\u3eAndropogon gerardii\u3c/i\u3e Vitman (Big Bluestem) at Konza Prairie, Kansas

Clone size of plants of Andropogon gerardii from Konza Prairie Biological Station, Manhattan, Kansas was estimated from spatial patterns of genetic variation, using proteins detected by starch gel electrophoresis and DNA content (ploidy) measured by flow cytometry. Unique multi-locus protein banding patterns and differences in ploidy were used to exclude plants as members of the same clone. Individual clones averaged about 2 m in diameter and areas of prairie of 100 m2 were calculated to contain an average of 31.8 genetic individuals

Discussion on \u27A.R. Wallace in the Light of Historical Method\u27 by John van Whye

The recent article by historian John van Wyhe purports to identify seventeen ‘myths’ concerning the life and work of naturalist Alfred Russel Wallace. Here we briefly describe what we feel is wrong with them, and refer to published literature that extend these arguments. Our objections do not extend to the ‘historical method’ van Wyhe adopts, but instead to the way he has ignored the criticisms of peers to the extent of not even acknowledging their scholarly articles

Media Attention on African Americans with Human Immunodeficiency Virus

Human immunodeficiency virus (HIV) is a disease that has captured the attention of the media in various ways and to varying degrees. One of the ongoing debates and areas of research in HIV that provide many opportunities for discovery is the disproportionate number of African Americans infected with HIV compared to the amount of attention they receive in the media. This manuscript addresses the question that has preoccupied the minds of many people: Why have African Americans infected with HIV received so little media attention? Analysis of this question suggests that there are many reasons for this lack of media attention. One reason in particular is the media tends to be much less attentive to diseases, such as HIV, that disproportionately burden blacks relative to whites. We also find that the media is reluctant to write about HIV in African Americans because it portrays them negatively. The media suggests that people are bombarded with negative news about African Americans and writing about them with regard to HIV only reinforces the negative. Finally, analysis reveals that in recent years African Americans with HIV have received more media attention due to the increase in rates of HIV in African Americans. This increase in media attention helps educate African Americans about the disease, reduces the stigma associated with it, and inspires African Americans to get tested and linked to care. In this way, African Americans with HIV can help the community stay virus-free
