History and super diversity
The article looks at the perspectives on history amongst adolescent children of different backgrounds living in inner-cities in England and builds on previous research in this area. The current article presents exploratory research which focuses on the views of particular groups of adolescents, namely those from long established settled immigrant communities; those from more recently arrived migrant and immigrant communities; and those from white indigenous communities. An inclusive, perspectival and dynamic approach towards history education is outlined and the underlying view of knowledge and implications for pedagogy of this approach discussed alongside comparisons with other approaches towards the subject. The exploratory work and analysis is used to generate a research agenda through which history for a super diverse society can be developed. Although the research was conducted in the English context, the issues it raises are pertinent elsewhere
Prevalence of sulfonamide resistance genes in bacterial isolates from manured agricultural soils and pig slurry in the United Kingdom
Prevalence of three sulfonamide resistance genes, sul1, sul2 and sul3 and sulfachloropyridazine (SCP) resistance was determined in bacteria isolated from UK manured agricultural clay soils and slurry samples, over a two year period. Slurry from tylosin-fed pigs amended with SCP and oxytetracycline (OTC) was used for manuring. Sul gene positive isolates were further screened for the presence of class 1 and 2 integrons. Phenotypic resistance to SCP was significantly higher in pig slurry and post application soil than in pre-application soil. Of 5isolates, 23 % carried sul1, 18 % sul2 and 9 % sul3 only. Two percent of isolates contained all three sul genes. Class 1 and class 2 integrons were identified in 5 % and 11.7 % of sul positive isolates. In previous reports, sul1 was linked to class 1 integrons, but in this study only 8 % of sul1 positive isolates carried the intI1 gene. Sulfonamide resistant pathogens were identified in slurry amended soil and soil leachate, including Shigella flexneri, Aerococcus spp. and Acinetobacter baumanni, suggesting a potential environmental reservoir. Sulfonamide resistance in Psychrobacter, Enterococcus and Bacillus spp. is reported for the first time, and this study also provides the first description of the genotype sul1, sul2 and sul3 outside the Enterobacteriacae, and in the soil environment

Integron prevalence and diversity in manured soil
Integron abundance and diversity were studied in soil amended with pig slurry. Real-time PCR illustrated a significant increase in class 1 integron prevalence post slurry-application with increased prevalence still evident at 10 months post-application. Culture dependent data revealed 10 genera, including putative human pathogens, carrying class 1 and 2 integrons
4-H Youth Development: The Past, the Present, and the Future
The 4-H Program within Cooperative Extension is more than 100 years old. As we celebrate 100 years of Cooperative Extension, the foundation built by the 4-H Program serves as grounds to meet the needs of today\u27s youth. The diversity of the youth who participate continues to grow, families continue to become less traditional, potential volunteers\u27 time continues to shrink, and the growing number of digital devices steal time. These changes demand 4-H adapt and innovate to remain relevant. This commentary examines the role that 4-H Youth Development will play in the next 100 years to face these challenges
"I treat my daughters not like my mother treated me" : migrant and refugee women's constructions and experiences of menarche and menstruation
Menstruation is a material reality at some point in most womenās lives. Yet, the discursive meaning assigned to menstruating bodies and the way in which they are experienced is dependent on the sociocultural and historical spaces which they occupy (Lee and Sasser-Coen 1996, 13). Across cultural contexts, menarche is constructed as a symbolic transition from childhood to womanhood, a period of growth and change, often linked with sexual maturation (Lee 2009, 622). While menstrual activists, artists, poets, and womenās rights organizations are challenging negative representations and practices surrounding menstruation (Bobel 2010, 42), dominant discourses often still portray menstruation as something dirty and disgusting, and a bodily function to be silenced and concealed (Brantelid, NilvĆ©r, and Alehagen 2014, 606; Mason et al. 2013, 4; see also Wood [Chapter 25] in this volume)
A five year outbreak of methicillin-susceptible Staphylococcus aureus phage type 53,85 in a regional neonatal unit
We identified a 5-year outbreak of a methicillin-susceptible Staphylococcus aureus (MSSA) strain, affecting 202 babies on a neonatal unit, by routine weekly phage typing all S. aureus isolates. Multiple staged control measures including strict emphasis on hand hygiene, environmental and staff surveillance sampling, and application of topical hexachlorophane powder failed to end the outbreak. S. aureus PT 53,85 (SA5385) was found on opened packs of StomahesiveĀ®, used as a neonatal skin protectant.
Only following the implementation of aseptic handling of StomahesiveĀ®, and the use of topical mupirocin for staff nasal carriers of SA5385, and for babies colonized or infected with S. aureus, did the isolation rate of SA5385 decline. DNA fingerprinting indicated that [gt-or-equal, slanted]95% of SA5385 isolates were clonal. In vitro death rates of SA5385 on StomahesiveĀ® with human serum were significantly lower than on StomahesiveĀ® alone (P = 0Ā·04), and on cotton sheet with serum (P = 0Ā·04), highlighting the potential of this material as a survival niche. Phage typing remains a valuable, inexpensive and simple method for monitoring nosocomial MSSA infection
Evolution of a clade of acinetobacter baumannii global clone 1, lineage 1 via acquisition of carbapenem- and aminoglycoside-resistance genes and dispersion of ISAba1
Ā© 2019 The Authors. Resistance to carbapenem and aminoglycoside antibiotics is a critical problem in Acinetobacter baumannii, particularly when genes conferring resistance are acquired by multiply or extensively resistant members of successful globally distributed clonal complexes, such as global clone 1 (GC1). Here, we investigate the evolution of an expanding clade of lineage 1 of the GC1 complex via repeated acquisition of carbapenem-and aminoglycoside-resistance genes. Lineage 1 arose in the late 1970s and the Tn6168/OCL3 clade arose in the late 1990s from an ancestor that had already acquired resistance to third-generation cephalosporins and fluoroquinolones. Between 2000 and 2002, two distinct subclades have emerged, and they are distinguishable via the presence of an integrated phage genome in subclade 1 and AbaR4 (carrying the oxa23 carbapenem-resistance gene in Tn2006) at a specific chromosomal location in subclade 2. Part or all of the original resistance gene cluster in the chromosomally located AbaR3 has been lost from some isolates, but plasmids carrying alternate resistance genes have been gained. In one group in subclade 2, the chromosomally located AbGRI3, carrying the armA aminoglycoside-resistance gene, has been acquired from a GC2 isolate and incorporated via homologous recombination. ISAba1 entered the common ancestor of this clade as part of the cephalosporin-resistance transposon Tn6168 and has dispersed differently in each subclade. Members of subclade 1 share an ISAba1 in one specific position in the chromosome and in subclade 2 two different ISAba1 locations are shared. Further shared ISAba1 locations distinguish further divisions, potentially providing simple markers for epidemiological studies
