The Birth of the Stars: A Participatory and Appreciative Action and Reflection Investigation into the Leadership and Development of a New Superleague Netball Club

This Participatory and Appreciative Action and Reflection (PAAR) investigation illustrates a leader’s first steps in a “valuesto-action” journey. Drawing on the interface between transformational leadership and organizational culture, this study focused on the birth of the Severn Stars—a professional netball club in the United Kingdom. In particular, this PAAR investigation explored how the leader’s values were operationalized through the club’s inaugural year. Fourteen operational managers, coaches, and players were individually interviewed in order to gain an appreciative gaze and subsequently reframe their lived experience. Results demonstrated how transformational leadership was manifested through the pragmatic deployment of club values and how the organizational culture was, in part, characterized by individualized consideration, intellectual stimulation, idealized influence, and inspirational motivation. These behaviors and the organizational culture were shown to enhance prosocial relationships and social connections across the club, the influence of the Super Stars, and stakeholders’ perceptions of autonomy

Using conversational data to determine lexical frequency in British Sign Language: The influence of text type

This paper presents findings from an objective lexical frequency study in British Sign Language (BSL) based on 24,823 tokens collected as part of the BSL Corpus Project. The BSL study is only the fourth objective frequency study involving sign languages to be reported and is also the first study for any sign language to be based on entirely on spontaneous conversational data. When compared to previous frequency studies (both spoken and signed), some similarities can be observed although differences that may be attributed to text type are also recorded. When compared with subjective frequency ratings collected for BSL, a positive relationship is reported (similar to what has been observed for spoken languages). This is in contrast to a previous study which suggested a much weaker relationship between the two; however, this conclusion was based on a frequency count derived from narratives. These differences highlight the importance of using frequency measures derived from natural and spontaneous data, an opinion that has been emphasised in the spoken language literature

Iconicity emerges and is maintained in spoken language

Iconicity is the property whereby signs (vocal or manual) resemble their referents. Iconic signs are easy to relate to the world, facilitating learning and processing. In this study, we examined whether the benefits of iconicity would lead to its emergence and to maintenance in language. We focused on shape iconicity (the association between rounded objects and round-sounding words like “bouba” and between spiky objects and spiky-sounding words like “kiki”) and motion iconicity (the association between longer words and longer events). In Experiment 1, participants generated novel labels for round versus spiky shapes and long versus short movements (Experiment 1a: text, Experiment 1b: speech). Labels for each kind of stimulus differed in a way that was consistent with previous studies of iconicity. This suggests that iconicity emerges even on a completely unconstrainted task. In Experiment 2 (Experiment 2a: text, Experiment 2b: speech), we simulated language change in the laboratory (as iterated learning) and found that both forms of iconicity were introduced and maintained through generations of language users. Thus, we demonstrate the emergence of iconicity in spoken languages, and we argue that these results reflect a pressure for language systems to be referential, which favors iconic forms in the cultural evolution of language (at least up to a point where it is balanced by other pressures, e.g., discriminability). This can explain why we have iconicity across natural languages and may have implications for debates on language origins. (PsycInfo Database Record (c) 2021 APA, all rights reserved

In Vitro Effects of Sports and Energy Drinks on Streptococcus mutans Biofilm Formation and Metabolic Activity

Purpose: Sports and energy drinks are being increasingly consumed and contain large amounts of sugars, which are known to increase Streptococcus mutans biofilm formation and metabolic activity. The purpose of this in vitro study was to investigate the effects of sports and energy drinks on S. mutans biofilm formation and metabolic activity. Methods: S. mutans UA159 was cultured with and without a dilution (1:3 ratio) of a variety of sports and energy drinks in bacterial media for 24 hours. The biofilm was washed, fixed, and stained. Biofilm growth was evaluated by reading absorbance of the crystal violet. Biofilm metabolic activity was measured by the biofilm-reducing XTT to a water-soluble orange compound. Results: Gatorade Protein Recovery Shake and Starbucks Doubleshot Espresso Energy were found to significantly increase biofilm (30-fold and 22-fold, respectively) and metabolic activity (2-fold and 3-fold, respectively). However, most of the remaining drinks significantly inhibited biofilm growth and metabolic activity. Conclusions: Several sports and energy drinks, with sugars or sugar substitutes as their main ingredients inhibited S. mutans biofilm formation. Among the drinks evaluated, Gatorade Protein Recovery Chocolate Shake and Starbucks Doubleshot Energy appear to have cariogenic potential since they increased the biofilm formation and metabolic activity of S. mutans

Lifetime determination of excited states in Cd-106

Two separate experiments using the Differential Decay Curve Method have been performed to extract mean lifetimes of excited states in 106 Cd. The inedium-spin states of interest were populated by the Mo-98(C-12, 4n) Cd-106 reaction performed at the Wright Nuclear Structure Lab., Yale University. From this experiment, two isomeric state mean lifetimes have been deduced. The low-lying states were populated by the Mo-96(C-13, 3n)Cd-106 reaction performed at the Institut fur Kernphysik, Universitat zu Koln. The mean lifetime of the I-pi = 2(1)(+) state was deduced, tentatively, as 16.4(9) ps. This value differs from the previously accepted literature value from Coulomb excitation of 10.43(9) ps

Population-based study of ischemic stroke risk after trauma in children and young adults.

OBJECTIVE:To quantify the incidence, timing, and risk of ischemic stroke after trauma in a population-based young cohort. METHODS:We electronically identified trauma patients (<50 years old) from a population enrolled in a Northern Californian integrated health care delivery system (1997-2011). Within this cohort, we identified cases of arterial ischemic stroke within 4 weeks of trauma and 3 controls per case. A physician panel reviewed medical records, confirmed cases, and adjudicated whether the stroke was related to trauma. We calculated the 4-week stroke incidence and estimated stroke odds ratios (OR) by injury location using logistic regression. RESULTS:From 1,308,009 trauma encounters, we confirmed 52 trauma-related ischemic strokes. The 4-week stroke incidence was 4.0 per 100,000 encounters (95% confidence interval [CI] 3.0-5.2). Trauma was multisystem in 26 (50%). In 19 (37%), the stroke occurred on the day of trauma, and all occurred within 15 days. In 7/28 cases with cerebrovascular angiography at the time of trauma, no abnormalities were detected. In unadjusted analyses, head, neck, chest, back, and abdominal injuries increased stroke risk. Only head (OR 4.1, CI 1.1-14.9) and neck (OR 5.6, CI 1.03-30.9) injuries remained associated with stroke after adjusting for demographics and trauma severity markers (multisystem trauma, motor vehicle collision, arrival by ambulance, intubation). CONCLUSIONS:Stroke risk is elevated for 2 weeks after trauma. Onset is frequently delayed, providing an opportunity for stroke prevention during this period. However, in one-quarter of stroke cases with cerebrovascular angiography at the time of trauma, no vascular abnormality was detected
