Multi-wavelength Radio Continuum Emission Studies of Dust-free Red Giants

Multi-wavelength centimeter continuum observations of non-dusty, non-pulsating K spectral-type red giants directly sample their chromospheres and wind acceleration zones. Such stars are feeble emitters at these wavelengths however, and previous observations have provided only a small number of modest S/N measurements slowly accumulated over three decades. We present multi-wavelength Karl G. Jansky Very Large Array thermal continuum observations of the wind acceleration zones of two dust-free red giants, Arcturus (Alpha Boo: K2 III) and Aldebaran (Alpha Tau: K5 III). Importantly, most of our observations of each star were carried out over just a few days, so that we obtained a snapshot of the different stellar atmospheric layers sampled at different wavelengths, independent of any long-term variability. We report the first detections at several wavelengths for each star including a detection at 10 cm (3.0 GHz: S band) for both stars and a 20 cm (1.5 GHz: L band) detection for Alpha Boo. This is the first time single luminosity class III red giants have been detected at these continuum wavelengths. Our long-wavelength data sample the outer layers of Alpha Boo's atmosphere where its wind velocity is approaching its terminal value and the ionization balance is becoming frozen-in. For Alpha Tau, however, our long-wavelength data are still sampling its inner atmosphere, where the wind is still accelerating probably due to its lower mass-loss rate. We compare our data with published semi-empirical models based on ultraviolet data, and the marked deviations highlight the need for new atmospheric models to be developed. Spectral indices are used to discuss the possible properties of the stellar atmospheres, and we find evidence for a rapidly cooling wind in the case of Alpha Boo. Finally, we develop a simple analytical wind model for Alpha Boo based on our new long-wavelength flux measurements

Podiatrists’ perspectives of the provision of foot health education for people with Rheumatoid Arthritis

IntroductionPatient education is considered to be a key role for podiatrists in the management of patients with Rheumatoid Arthritis (RA). However there is no evidence that identifies or supports the most appropriate strategies and content for its delivery. The aim of this study was to identify the nature and content of the current provision by podiatrists in relation to foot health education for people with RA. Any potential barriers to its provision were explored.MethodTwelve members (all female) of the Northwest Podiatry Clinical Effectiveness Group for Rheumatology volunteered to take part in a Focus Group, ranging from newly qualified podiatrists with an interest in working within rheumatology to those with extensive years of experience managing patients with RA (working within Primary and Secondary care). The dialogue was recorded digitally, transcribed verbatim and analysed using a structured, thematic approach by the lead author. The full transcription was verified as accurate by the focus group to ensure trustworthiness of the data.ResultsFive overarching themes emerged from the data, each with it’s own set of sub-themes, these were, 1. The Essence of Patient Education [information provision & empowerment,] 2. The content [what, why, when & by whom], 3. Barriers to Provision [external, psychosocial, educational, concordance & professional experience], 4. The therapeutic relationship [patient/practitioner knowledge & attitudes, influence of age & gender, role/title confusion, taboo subject areas] and 5. Tools of the trade [group v individual, verbal & written, audio-visual, web-based].DiscussionThis methodological approach of this study has revealed aspects of patient education, which this group of podiatrists find to be most influential in its overall delivery from their perspective. This adds new knowledge as no previous study has been carried out. The lead author is currently exploring the same area with patient participants. Ultimately the aim is to achieve the development of a patient-centred and negotiated approach to the provision of foot health education for people with RA

Competencies Needed to be Successful County Agents and County Supervisors

This study describes the competencies that county agents and county supervisors in Arkansas believe are important for future success. Participants identified 57 core competencies, with character traits being the top-rated items. Having a farm background and 4-H experience were not ranked as highly important. The competency area Faculty/Staff Relations was rated as the most important for both agents and supervisors. Management Skills were ranked more important for supervisors, while Public Relations and Work Habits were rated more important for agents. Training should be provided to increase agent and supervisor competencies in those areas identified as very important

Transforming the news value chain in the social era: a technical perspective

Purpose: This paper develops a conceptual framework to unde rstand the influence that the social era is having on the value chain of the local news industry. We theoretically advance value chain theory by firstly, considering the influence of community type and age on consumption and secondly exploring the role that consumers can play in value adding activities. Our theoretical contribution lies in moving from a transactional approach towards consumer relationships in the value chain towards managing consumers as a source of relational value (e.g. co-creation and integrated perspectives). Design: The conceptual framework is theoretically positioned in relation to community and digital community practices in the social era. A series of research questions are presented, then these questions are explored drawing on empirical data from the PEW database. We then advance the framework further to consider news firm strategy towards its consumers. 15 in-depth executive interviews were conducted with local news organizations in the Manchester area of the UK. Findings: We illustrate that different types of communities (merging cohorts and locations) are influencing levels of technological and social connectivity within the value chain. We also find that the news industry is experimenting with reconfiguring its consumer relations from a purely transactional to a co-created and participatory value added activity in the social era. In terms of its policy impact our findings show that the whole strategic value chain ideology of the news industry needs to change radically; away from its largely transactional (and lack of trust) approach in the ability of consumers to create value in the supply chain (other than to buy a product) and, move towards much greater consumer involvement and participation in value chain processes (creation, production and distribution of news products and services). Originality/value: The change associated with social media and connec tivity is changing the way that different community types and consumer groups are now consuming and participating in news content creation. Unlike previous studies we show that there is variance and complexity in the levels of consumer participation by community type/age group. Using the PEW data we contribute to knowledge on the value creation strategy of news firms in the social era, by identifying how communicative, social and communicative logics influence value and co-creation activities in the local news supply chain. Through our interviews we advance value co-creation theory from its strategic and marketing origins to operational and supply chain implementation

Copper-catalyzed asymmetric oxidation of sulfides

Copper-catalyzed asymmetric sulfoxidation of aryl benzyl and aryl alkyl sulfides, using aqueous hydrogen peroxide as the oxidant, has been investigated. A relationship between the steric effects of the sulfide substituents and the enantioselectivity of the oxidation has been observed, with up to 93% ee for 2-naphthylmethyl phenyl sulfoxide, in modest yield in this instance (up to 30%). The influence of variation of solvent and ligand structure was examined, and the optimized conditions were then used to oxidize a number of aryl alkyl and aryl benzyl sulfides, producing sulfoxides in excellent yields in most cases (up to 92%), and good enantiopurities in certain cases (up to 84% ee)

Asymmetric oxidation of sulfides

This review discusses synthesis of enantiopure sulfoxides through the asymmetric oxidation of prochiral sulfides. The use of metal complexes to promote asymmetric sulfoxidation is described in detail, with a particular emphasis on the synthesis of biologically active sulfoxides. The use of non-metal-based systems, such as oxaziridines, chiral hydroperoxides and peracids, as well as enzyme-catalyzed sulfoxidations is also examined

Temporal Evolution of the Size and Temperature of Betelgeuse's Extended Atmosphere

We use the Very Large Array (VLA) in the A configuration with the Pie Town (PT) Very Long Baseline Array (VLBA) antenna to spatially resolve the extended atmosphere of Betelgeuse over multiple epochs at 0.7, 1.3, 2.0, 3.5, and 6.1 cm. The extended atmosphere deviates from circular symmetry at all wavelengths while at some epochs we find possible evidence for small pockets of gas significantly cooler than the mean global temperature. We find no evidence for the recently reported e-MERLIN radio hotspots in any of our multi-epoch VLA/PT data, despite having sufficient spatial resolution and sensitivity at short wavelengths, and conclude that these radio hotspots are most likely interferometric artefacts. The mean gas temperature of the extended atmosphere has a typical value of 3000 K at 2 $R_{\star}$ and decreases to 1800 K at 6 $R_{\star}$, in broad agreement with the findings of the single epoch study from Lim et al. (1998). The overall temperature profile of the extended atmosphere between $2 R_{\star} \lesssim r \lesssim 6 R_{\star}$ can be described by a power law of the form $T_{\mathrm{gas}}(r) \propto r^{-0.6}$, with temporal variability of a few 100 K evident at some epochs. Finally, we present over 12 years of V band photometry, part of which overlaps our multi-epoch radio data. We find a correlation between the fractional flux density variability at V band with most radio wavelengths. This correlation is likely due to shock waves induced by stellar pulsations, which heat the inner atmosphere and ionize the more extended atmosphere through radiative means. Stellar pulsations may play an important role in exciting Betelgeuse's extended atmosphere
