Following the COVID-19 pandemic, public organizations are tempted to introduce practices that allow employees work independently of time and space. However, little is known about impact such on employees’ outcomes. The purpose this study investigate relationship between New Ways Working (NWW) in-role performance, while also considering role outcome-oriented culture plays in relationship. Hierar...

In Caulobacter crescentus, the temporal and spatial expression of late flagellar genes is regulated by the sigma54 transcriptional activator, FlbD. Genetic experiments have indicated that the trans-acting factor FliX regulates FlbD in response to the progression of flagellar assembly, repressing FlbD activity until an early flagellar basal body structure is assembled. Following assembly of this...

A multivalent live oral vaccine against both Shigella spp. and enterotoxigenic Escherichia coli (ETEC) is being developed based on the hypothesis that protection can be achieved if attenuated shigellae express ETEC fimbrial colonization factors and genetically detoxified heat-labile toxin from a human ETEC isolate (LTh). Two detoxified derivatives of LTh, LThK63 and LThR72, were engineered by s...

We present integral field spectroscopy of the nebular line emission in a sample of 9 brightest cluster galaxies (BCGs). The sample was chosen to probe both cooling flow and non-cooling flow clusters, as well as a range of cluster X-ray luminosities. The line emission morphology and velocity gradients suggest a great diversity in the properties of the line emitting gas. While some BGCs show evid...

The transcription factor FlbD regulates the temporal and spatial transcription of flagellar genes in the bacterium Caulobacter crescentus. Activation of FlbD requires cell cycle progression and the assembly of an early (class II) flagellum structure. In this report, we identify 20 independent gain-of-function mutations in flbD that relieve regulation by flagellar assembly. One of these, flbD-12...

The genes that encode the enterotoxigenic Escherichia coli (ETEC) CS4 fimbriae, csaA, -B, -C, -E, and -D', were isolated from strain E11881A. The csa operon encodes a 17-kDa major fimbrial subunit (CsaB), a 40-kDa tip-associated protein (CsaE), a 27-kDa chaperone-like protein (CsaA), a 97-kDa usher-like protein (CsaC), and a deleted regulatory protein (CsaD'). The predicted amino acid sequences...
