This two-part study with working adults examines which communication behaviors occur at work and how these communication behaviors are evaluated. Through an analysis of organizational communication publications (articles, organizational case studies, textbooks), the authors identified 343 communication behaviors; sorting analysis reduced this list to 163 verbal communication behaviors used in the workplace. In Study 1, using an online survey, 126 working adults identified which of these communication behaviors had been heard or observed the previous day in the workplace. Forty-four communication behaviors were identified by 50% or more of the participants, indicating their frequent use in the workplace. In Study 2, 331 working adults evaluated their effectiveness on the 44 verbal communication behaviors. Factor analysis reduced that list to 36 verbal workplace communication behaviors composed of four factors: information sharing, relational maintenance, expressing negative emotion, and organizing communication behaviors. The Workplace Communication Behavior Inventory is presented.

Gold nanoclusters are promising candidates as biological markers without having toxic effects like fluorescent quantum dots. Herein, bovine serum albumin (BSA) protein stabilized gold nanoclusters of two different sizes emitting at 410 and 645 nm have been synthesized. These nanoclusters have been shown to interact with molecular oxygen differentially. Spectroscopic and chemical evidences show that dioxygen molecule gets adsorbed at two different orientations on the nanoclusters. The orientation motifs have been hypothesized to be superoxo and peroxo types on the smaller and the larger gold nanoclusters, respectively. Due to the difference in attachments, the oxygen molecule shows opposite changes in fluorescence intensity for the nanoclusters. The fluorescence intensity of the blue emitting nanocluster shows a profuse enhancement whereas the red emitting species shows quenching of emission. Superoxo type adsorption of the oxygen molecule on the blue emitting gold nanoclusters induce formation of singlet oxygen that in turn enhances the fluorescence intensity of the species. This could be verified by oxidation of diaminobenzidine (DAB) by singlet oxygen. Enhancement in fluorescence intensity of the blue emitting gold nanoclusters with an increase in concentration of molecular oxygen may enable them to be good candidates in bioimaging and detection.

Within two weeks from the first detection of the SARS-CoV-2 positive patient on 21st February, from Lombardy the disease has spread over every region in Italy. The main objective of this study is to identify spatial effects and spatiotemporal patterns of the outbreak of COVID-19 in different regions of Italy. Spatial indicators for different periods, as Moran's I, local Moran, LISA clusters, Getis and Ord G, and scatterplots are used for this purpose. Results confirm the great presence of spatial effects as well as changes in spatial regimes between the quarantine and the easing phase. The evidence could be of help for policymakers to a proper assessments of health strategies aware of local characteristics.

Coumarin 6 precipitates in water as microcrystals resulting in a considerable loss in fluorescence yield. Differential interaction of the microcrystals with cyclodextrins of different cavity size enhances the fluorescence yield of the dye by 160 fold in some cases. Highly fluorescent ultrathin lamellar entities form through hydrogen bonding. † Electronic supplementary information (ESI) available: Structure of C6, AFM and SEM images of C6 aer incubation in water (with 1% methanol) for 30 minutes at room temperature, uorescence spectra of C6 in a-, band g-CDs in aqueous environment and time resolved uorescence decay prole for C6 in presence of band g-CDs.

I. Introduction The Carnmenellis granite and its metamorphic aureole were mapped, in 1839, by de la Beche. The area has since been re-surveyed by the Geological Survey and the results recorded in the one-inch maps, nos. 352 and 359 (New Series) and in the Survey Memoir on the Falmouth and Camborne district (Hill & MacAlister, 1906). The granite is an important unit in the chain of post-Carboniferous granite intrusions forming the backbone of the peninsula of Cornwall and Devon. The consanguinity of these intrusions has long been known, but the recognition of the composite character of individual intrusions is comparatively recent. Intrusive relationship between major composite masses was observed on Dartmoor by the members of the Geological Survey (Reid & others, 1912), Brammall (1923), and Osman (1928), and on Bodmin Moor by myself (1927). Intrusion sequences are discussed by Brammall (1923 & 1932) and Osman (1928). Important petrological contrasts between the Devonian and the Cornish granites were pointed out by Flett and Dewey (Reid & others, 1912), and problems of variation within individual complexes have since been made the basis of detailed study by Osman with special reference to the Dartmoor and Scilly Isles masses, by Richardson (1923) dealing with the St. Austell granite, and by myself in a paper on the Bodmin Moor granite (1927), and the Carnmenellis granite, the subject of the present contribution. I would add that, subsequent to the presentation of the paper to the Society, I have had the advantage of re-examining my analytical data
