Before the emergence of SARS-CoV-2, the virus that causes COVID-19, influenza activity in the United States typically began to increase in the fall and peaked in February. During the 2021-22 season, influenza activity began to increase in November and remained elevated until mid-June, featuring two distinct waves, with A(H3N2) viruses predominating for the entire season. This report summarizes influenza activity during October 3, 2021-June 11, 2022, in the United States and describes the composition of the Northern Hemisphere 2022-23 influenza vaccine. Although influenza activity is decreasing and circulation during summer is typically low, remaining vigilant for influenza infections, performing testing for seasonal influenza viruses, and monitoring for novel influenza A virus infections are important. An outbreak of highly pathogenic avian influenza A(H5N1) is ongoing; health care providers and persons with exposure to sick or infected birds should remain vigilant for onset of symptoms consistent with influenza. Receiving a seasonal influenza vaccine each year remains the best way to protect against seasonal influenza and its potentially severe consequences.The United States influenza surveillance system is a collaborative effort between CDC and its many partners in state, local, and territorial health departments, public health and clinical laboratories, vital statistics offices, health care providers, hospitals, clinics, emergency departments, and long-term care facilities. This report is a summary of the 2021-22 influenza season. This report was reviewed by CDC and was conducted consistent with applicable federal law and CDC policy. †

Purpose – As mastering the two-minute entrepreneurial pitch is a key skill required of entrepreneurs and all those who have to sell an idea in a business context, the purpose of this paper is to analyse successful entrepreneurial pitches in order to provide practical pitch-related advice to entrepreneurs and to business school instructors developing pedagogical materials. Design/methodology/approach – As mastering the two-minute entrepreneurial pitch is a key skill required of entrepreneurs and all those who have to sell an idea in a business context, this paper aims to analyse successful entrepreneurial pitches in order to provide practical pitch-related advice to entrepreneurs and to business school instructors developing pedagogical materials. Findings – A ten-stage discourse framework was shown to underlie most pitches and typical linguistic exponents and rhetorical devices were identified. While there was a strong correlation between linguistic exponents and particular organisational stages, it was not possible to map the rhetorical strategies or tropes onto the organisational stages. The rhetorical framework provides a macro-structure to help entrepreneurs manipulate key content, whereas the linguistic framework highlights the salient grammatical, organisational, syntactic and lexical features of a successful pitch. Research limitation – The sample of entrepreneurial pitches analysed is too small to be totally representative of the entrepreneurial pitch in general. However, this in-depth multi-dimensional analysis provides initial research into the canonical features of the entrepreneurial pitch. Practical implication – This study provides an actionable, best practice, discoursal template for the entrepreneurial pitch together with the typical linguistic exponents and rhetorical features. The findings should sensitise entrepreneurs and instructors to salient macro- and micro-features of the entrepreneurial pitch. Originality value – To the authors’ knowledge, this is the first study that has been carried out that takes a multi-dimensional analysis approach (both rhetorical and linguistic/discourse analysis) to deconstruct the entrepreneurial pitch.

The transmission of satellite signals at two widely spaced frequencies allows correction of the ionospheric delay. Both GPS and GLONASS transmit such signals, and to date there have been no published dual frequency GLONASS studies. This paper shows the fundamental accuracy of the Leeds University multichannel GPS/GLONASS receiver. Details are then given of the processing methods that have been used to obtain the ionospheric group delay using GLONASS L1 and L2 P‐code measurements. Examples of the measured delay are provided and compared with the GPS model. Navigation results are shown using the P‐code phase at L1 only and with a combination of the L1 and L2 measurements. An analysis of the accuracy of the P‐code pseudorange and navigation capability is presented.
