Organic farming policies and the growth of the organic sector in Denmark and the UK: a comparative analysis
There has been little systematic analysis of the extent to which organic farming policies have influenced growth in the organic sector. Analyses of organic farming policy instruments, for the most part, provide extensive and detailed reviews of instruments applied either in a single country or across countries. Hence, there is a great need to examine systematically whether there is a relationship between the introduction of organic farming policies and the growth of the organic food sector, and whether particular designs of organic farming policies are more effective than others. In this paper, we take the first step in the endeavour of analysing the effects of organic farming by undertaking an econometric analysis of the relationship between organic farming policies in Denmark and the UK and their effects on the number of farmers and growers converting to organic production

Can rock-rubble groynes support similar intertidal ecological communities to natural rocky shores?
© 2020 by the authors. Despite the global implementation of rock-rubble groyne structures, there is limited research investigating their ecology, much less than for other artificial coastal structures. Here we compare the intertidal ecology of urban (or semi-urban) rock-rubble groynes and more rural natural rocky shores for three areas of the UK coastline. We collected richness and abundance data for 771 quadrats across three counties, finding a total of 81 species, with 48 species on the groynes and 71 species on the natural rocky shores. We performed three-way analysis of variance (ANOVA) on both richness and abundance data, running parallel analysis for rock and rock-pool habitats. We also performed detrended correspondence analysis on all species to identify patterns in community structure. On rock surfaces, we found similar richness and abundance across structures for algae, higher diversity and abundance for lichen and mobile animals on natural shores, and higher numbers of sessile animals on groynes. Rock-pool habitats were depauperate on groynes for all species groups except for sessile animals, relative to natural shores. Only a slight differentiation between groyne and natural shore communities was observed, while groynes supported higher abundances of some 'at risk' species than natural shores. Furthermore, groynes did not differ substantially from natural shores in terms of their presence and abundance of species not native to the area. We conclude that groynes host similar ecological communities to those found on natural shores, but differences do exist, particularly with respect to rock-pool habitats
High fidelity sorting of remarkably similar components via metal-mediated assembly.
Subtle differences in ligand coordination angle and rigidity lead to high fidelity sorting between individual components displaying identical coordination motifs upon metal-mediated self-assembly. Narcissistic self-sorting can be achieved between highly similar ligands that vary minimally in rigidity and internal coordination angle upon combination with Fe(ii) ions and 2-formylpyridine. Selective, sequential cage formation can be precisely controlled in a single flask from a mix of three different core ligands (and 33 total components) differing only in the hybridization of one group that is uninvolved in the metal coordination process
Adolescent Pregnancy and Sexually Transmitted Diseases: Case Report
More than 1 million teenagers become pregnant every year in the United States. Nearly one-half of the pregnancies are carried to term, while a similar number end in abortion. In Michigan this amounts to approximately 34,000 teenage pregnancies (ages 15 to 19). These adolescent patients have a high incidence of sexually transmitted diseases (STDs). Of the pregnant teens at Henry Ford Hospital. 60% present with one or more STDs. We discuss the case of a 13-year-old pregnant girl who presented at five weeks estimated gestation with gonorrhea, chlamydia, and appendiceal perforation, resulting in subsequent spontaneous abortion. Further discussion focuses on common STDs in pregnant adolescents
