Organisational culture of hospitals to predict turnover intentions of professional nurses

Abstract: The objective of this study was to determine if organisational culture predicts turnover intentions of professional nurses A predictive model with organisational culture and various proposed mediating variables, namely knowledge sharing, organisational commitment, organisational citisenship behaviour and job satisfaction, as well as various demographic variables was developed to determine turnover intentions through applying General Linear Modelling A correlational design with questionnaires was used A sample of professional nurses (N = 530) in private and provincial hospitals was obtained The results indicate that organisational culture has a significantly negative correlation with turnover intentions Organisational culture also interacted with job satisfaction, knowledge sharing, and the white professional nurses’ category to decrease turnover intentions and with Organisational Citisen Behaviours to increase turnover intentions in a final predictive model It is therefore recommended that nursing employers seriously embark on strategies to improve the organisational culture to retain their talent Opsomming Die doel van die studie was om te bepaal of organisasie-kultuur arbeidsomset-voornemens van professionele verpleegkundiges voorspel ‘n Voorspellingsmodel met organisasiekultuur en verskeie voorgestelde tussenkomende veranderlikes, naamlik kennisdeling, organisasieverbintenis, organisasie-burgerskapsgedrag en werkstevredenheid, asook verskeie demografiese veranderlikes was ontwikkel deur Algemene Liniere Modellering ’n Korrelasie-ontwerp met behulp van vraelyste is gebruik ‘n Steekproef van professionele verpleegkundiges (N = 530) in private en provinsiale hospitale is verkry Die resultate toon dat organisasie-kultuur betekenisvol negatief korrelleer met arbeidsomsetvoornemens Organisasiekultuur het ook in interaksie met werkstevredenheid en kennisdeling, asook die kategorie blanke verpleegkundiges in ‘n finale model arbeidsomsetvoornemens verlaag en saam met organisasieburgerskapsgedrag arbeidsom-setvoornemens verhoog Daar word aanbeveel dat werkgewers oorweging skenk aan intervensies wat die organisasiekultuur gunstiger maak om personeel te behou

Microbial processing of fruit and vegetable wastes into potential biocommodities: a review.

Abstract: The review focuses on some of the high value-end biocommodities, such as fermented beverages, single-cell proteins, single-cell oils, biocolors, flavors, fragrances, polysaccharides, biopesticides, plant growth regulators, bioethanol, biogas and biohydrogen, developed from the microbial processing of fruit and vegetable wastes. Microbial detoxification of fruit and vegetable processing effluents is briefly described. The advances in genetic engineering of microorganisms for enhanced yield of the above-mentioned biocommodities are elucidated with selected examples. The bottleneck in commercialization, integrated approach for improved production, techno-economical feasibility and real-life uses of some of these biocommodities, as well as research gaps and future directions are discussed.

Phylogenomic Analysis of a 55.1-kb 19-Gene Dataset Resolves a Monophyletic Fusarium that Includes the Fusarium solani Species Complex.

Abstract: Scientific communication is facilitated by a data-driven, scientifically sound taxonomy that considers the end-user's needs and established successful practice. Previously (Geiser et al. 2013; Phytopathology 103:400-408. 2013), the Fusarium community voiced near unanimous support for a concept of Fusarium that represented a clade comprising all agriculturally and clinically important Fusarium species, including the F. solani Species Complex (FSSC). Subsequently, this concept was challenged by one research group (Lombard et al. 2015 Studies in Mycology 80: 189-245) who proposed dividing Fusarium into seven genera, including the FSSC as the genus Neocosmospora, with subsequent justification based on claims that the Geiser et al. (2013) concept of Fusarium is polyphyletic (Sandoval-Denis et al. 2018; Persoonia 41:109-129). Here we test this claim, and provide a phylogeny based on exonic nucleotide sequences of 19 orthologous protein-coding genes that strongly support the monophyly of Fusarium including the FSSC. We reassert the practical and scientific argument in support of a Fusarium that includes the FSSC and several other basal lineages, consistent with the longstanding use of this name among plant pathologists, medical mycologists, quarantine officials, regulatory agencies, students and researchers with a stake in its taxonomy. In recognition of this monophyly, 40 species recently described as Neocosmospora were recombined in Fusarium, and nine others were renamed Fusarium. Here the global Fusarium community voices strong support for the inclusion of the FSSC in Fusarium, as it remains the best scientific, nomenclatural and practical taxonomic option available.
