Bryophytes of Uganda : 1., BBS Tropical Bryology Group expeditions, 1996-1998 ; introduction and collecting sites

The British Bryological Society Tropical Bryology Group (TBG) undertook three expeditions to Uganda, in Jan-Feb 1996, Jan-Feb 1997 and June-Jul 1998. Collections were made from 134 sites, mainly from national parks and forest reserves in western and southern Uganda

Bryophytes of Uganda : 4., new and additional records, 2

20 hepatics and 16 mosses are reported new to Uganda, 1 moss being also new to Africa. A further 6 taxa are recorded for the second time from Uganda

Liquefaction and Surface Settlement in the Marina District

This paper evaluates the liquefaction potential of sands within the Marina District. Three types of underlying potentially liquefiable soil deposits are studied: (A) Hydraulic fill, (B) Artificial fill, and (C) Strawberry Island and other modern beach deposits. A liquefaction analysis for each of these deposits is conducted. It is suggested that a Peak Ground Acceleration (PGA) of approximately 0.1g is needed in the Marina District to initiate liquefaction. Relations between PGA and thickness of liquefiable soil, as well as potential surface settlement are presented. These relationships are useful for the study of expected performance of the Marina District in future earthquakes. The results can also be used to evaluate possible ground modification methods, utility design, or structural retrofit designs

British Bryological Society expedition to Mulanje Mountain, Malawi : 13., new and other unpublished records

Further results are provided of the 1991 British Bryological Society Expedition to Mulanje Mt., Malawi including 168 taxa of bryophyte, comprising 72 taxa of liverwort (38 new to Malawi) and 96 taxa of mosses (45 new to Malawi)

Bryophytes of Uganda : 2., new and interesting records

51 hepatics and 46 mosses are reported new to Uganda, including one moss new to Africa, one hepatic and two mosses new to mainland Africa, and 2 hepatics that are otherwise known only from their type collection

The Impacts of Global Warming on Appalachian Wildflower Phenologies

Public and private interest in global warming has prompted exploration of the impacts this phenomenon may impart on ecosystem functions. Flowering phenology has been one of the areas many scientists believe is particularly susceptible to the impacts of anthropogenic warming. Over three weekends in spring of 2008, the vernal herb community was surveyed at five sites within the Great Smoky Mountains regions of the southern Appalachian Mountains. The intent was to capture the naturally occurring elevational gradient and determine if the temperature cue for blooming was the same for all co-flowering species in the study. This information would allow for conjecture on the impacts of climate change on co-flowering communities. Initial findings were inconclusive because low sample size prevented statistical analysis

Weight Stigmatization Among Hispanic American Children

This study was designed to examine weight stigmatization among Hispanic American children. Fifty-five fifth grade students from a large, urban school district in Southern California were asked to rank six samesex drawings of children with various physical characteristics (related to weight or disability) in order of friend preference (1 = the most preferred, and 6 = the least preferred friend). Positive and negative adjectives were then assigned to the average-weight and obese drawings using the Adjective Checklist (ACL). The majority of the participants (60%) chose the average-weight child as the most preferred and 46% identified the obese child as the least preferred friend. In addition, the average-weight child was assigned more positive and fewer negative adjectives compared to the obese child. Significant differences in ACL composite scores between normal weight and overweight drawings were also found (p = 0.00). It appears that weight stigmatization is present in the current sample, which suggests that Hispanic children living in the U.S. may adopt negative attitudes about weight that are similar to American culture

Bryophytes of Uganda : 6., new and additional records, 3.

12 hepatics and 32 mosses are reported new to Uganda, 1 moss being also new to Africa, and 1 liverwort new to mainland Africa. Ectropothecium plumigerum (Broth.) Hedenäs is a new combination (basionym: Isopterygium plumigerum Broth.) with a new synonym Taxicaulis plumirameus Müll.Hal. nom. nud., and Taxiphyllum maniae (Renauld & Paris) M. Fleisch. is a new synonym of Taxiphyllum taxirameum (Mitt.) M.Fleisch. Three mosses are removed from the Uganda list

An Environmental Science and Engineering Framework for Combating Antimicrobial Resistance

On June 20, 2017, members of the environmental engineering and science (EES) community convened at the Association of Environmental Engineering and Science Professors (AEESP) Biennial Conference for a workshop on antimicrobial resistance. With over 80 registered participants, discussion groups focused on the following topics: risk assessment, monitoring, wastewater treatment, agricultural systems, and synergies. In this study, we summarize the consensus among the workshop participants regarding the role of the EES community in understanding and mitigating the spread of antibiotic resistance via environmental pathways. Environmental scientists and engineers offer a unique and interdisciplinary perspective and expertise needed for engaging with other disciplines such as medicine, agriculture, and public health to effectively address important knowledge gaps with respect to the linkages between human activities, impacts to the environment, and human health risks. Recommendations that propose priorities for research within the EES community, as well as areas where interdisciplinary perspectives are needed, are highlighted. In particular, risk modeling and assessment, monitoring, and mass balance modeling can aid in the identification of “hot spots” for antibiotic resistance evolution and dissemination, and can help identify effective targets for mitigation. Such information will be essential for the development of an informed and effective policy aimed at preserving and protecting the efficacy of antibiotics for future generations
