Comparative Analysis of Genome Sequences Covering the Seven Cronobacter Species

Abstract: Background Species of Cronobacter are widespread in the environment and are occasional food-borne pathogens associated with serious neonatal diseases, including bacteraemia, meningitis, and necrotising enterocolitis. The genus is composed of seven species: C. sakazakii, C. malonaticus, C. turicensis, C. dublinensis, C. muytjensii, C. universalis, and C. condimenti. Clinical cases are associated with three species, C. malonaticus, C. turicensis and, in particular, with C. sakazakii multilocus sequence type 4. Thus, it is plausible that virulence determinants have evolved in certain lineages.

Evolving research on expatriates: what is ‘known’ after four decades (1970–2012)

Abstract: The purpose of this paper was to provide a comprehensive review of the evolving research on a still key challenge for human resource management (HRM) in the globalized business of today: the expatriates and their impact on business performance. Research of four decades was reviewed to show what was known and what was not yet known. A bibliometric analysis was conducted to build a conceptual map of the evolving research. Up to 438 papers published in 104 different journals by 233 authors were analyzed. Most of the literature studies and research does not show a systematic approach, so this review may be useful for scholars and practitioners in the field of HRM and International Business Management in order to advance into the next stage of development on how to deal with and take advantage of hiring expatriates. Even after more than four decades of intensive research, the literature on expatriation is still nascent and requires higher order content. New contexts and organizations should be included in the research agenda, while an effort must be made in systematic approaches and in building higher order content in the international HRM field.

Comparison of Media for the Isolation of Enterobacter sakazakii

Abstract: Enterobacter sakazakii is associated with neonatal infections and is occasionally present at low levels (<1 CFU/g) in powdered infant formula milk (IFM). It has been previously reported that some E. sakazakii strains do not grow in standard media for Enterobacteriaceae and coliform bacteria; therefore, a reliable method is needed for recovery of the organism. Three E. sakazakii enrichment broths-Enterobacteriaceae enrichment broth (EE), E. sakazakii selective broth (ESSB), and modified lauryl sulfate broth (mLST)-were compared with a novel broth designed for maximum recovery of E. sakazakii, E. sakazakii enrichment broth (ESE). One hundred seventy-seven strains (100%) grew in ESE, whereas between 2 and 6% of strains did not grow in EE, mLST, or ESSB. E. sakazakii possesses alpha-glucosidase activity, and a number of selective, chromogenic agars for E. sakazakii isolation based on this enzyme have been developed. E. sakazakii isolation agar produced fewer false-positive colonies than did Druggan-Forsythe-Iversen agar. However, the latter supported the growth of more E. sakazakii strains. It was also determined that 2% of E. sakazakii strains did not produce yellow pigmentation on tryptone soya agar at 25 degrees C, a characteristic frequently cited in the identification of E. sakazakii. The recovery of desiccated E. sakazakii (0.2 to 2000 CFU/25 g) from powdered IFM in the presence of a competing flora was determined with various enrichment broths and differential selective media. Current media designed for the isolation and presumptive identification of E. sakazakii do not support the growth of all currently known E. sakazakii phenotypes; therefore, improvements in the proposed methods are desirable.

Circular Product Design. A Multiple Loops Life Cycle Design Approach for the Circular Economy

Abstract: The circular economy is a high priority subject of discussion in the current political and academic contexts; however, practical approaches in relevant disciplines like design are in need of development. This article proposes a conceptual framework for circular product design, based on four multiple loops strategies: (I) design to slow the loops, (II) design to close the loops, (III) design for bio-inspired loops, and (IV) design for bio-based loops. Recent literature, notably on life cycle design strategies, the circular economy conceptual model and the European Commission’s Circular Economy Package, is reviewed and product design cases illustrating each of the proposed are analysed. The article argues that different ‘circular’ approaches centred upon the life cycle design phases can provide practical guiding strategies during the design process and thus promote sustainable design solutions for the circular economy within the United Nation’s sustainable development goals.
