Tai Chi for Older Adult Wellness: A Scoping Review and Proposed Study

PURPOSE: Tai Chi is a moderate-intensity exercise, which consists of slow fluid movements, appropriate for older adults. The five primary styles of Tai Chi include, Chen, Yang, Hao, Wu and Sun, where each style focuses on certain movements and functions. The purpose of this scoping review is to evaluate the impact of Tai Chi on the health and well-being of older adults. METHODS: Google Scholar and an university library’s OneSearch feature were used to locate relevant articles on Tai Chi for older adults. The OneSearch indexed several databases relevant to exercise science including PubMed, SPORTDiscus and Web of Science were the primary article databases used. RESULTS: Tai Chi provides physiological and psychological health benefits such as improved physical function and reduced mood disturbances. Tai Chi is versatile as it is used for fall prevention, rehabilitation, socialization and improving self-efficacy. These cited improvements are reported across all the five primary styles of Tai Chi. There are some known barriers to Tai Chi participation, such as unfamiliarity with Tai Chi’s history and benefits. There is limited evidence on whether the style of Tai Chi that is practiced can mitigate these barriers. CONCLUSION: Based on the findings, we still need to know the preferred Tai Chi style among older adults. There is need for qualitative study that will determine why older adults are interested or disinterred in Tai Chi and which style is most appealing to them

Intercultural ethics: questions of methods in language and intercultural communication

This paper explores how questions of ethics and questions of method are intertwined and unavoidable in any serious study of language and intercultural communication. It argues that the focus on difference and solution orientations to intercultural conflict has been a fundamental driver for theory, data collection and methods in the field. These approaches, the paper argues, have created a considerable consciousness raising industry, with methods, trainings and ‘critical incidents’, which ultimately focus intellectual energy in areas which may be productive in terms of courses and publications but which have a problematic basis in their ethical terrain. Dieser Artikel untersucht wie ethische und methodische Fragen nicht nur ineinander greifen, sondern in keiner ernstzunehmenden Studie ueber Sprache und interkulturelle Kommunikation ausgelassen werden duerfen. Es wird hier argumentiert, dass der Schwerpunkt auf Verschiedenheit und Problemorientierung im interkulturellen Konflikt einen wesentlichen Einfluss auf theoretische Entwicklungen, Datenerhebung und Methoden in diesem Bereich hatte. Dieser Artikel legt auch dar, wie diese Ansaetze eine betraechtliche ‘Bewusstseinsbildungs – Branche' erzeugt haben, mit Methoden, Trainings, und ‘kritischen Interaktionssituationen’, welche letztendlich allen intellektuellen Arbeitseifer auf Bereiche konzentriert hat, die zwar ertragreich sind in Bezug auf Kurse und Publikationen, jedoch eine problematische Grundlage im ethischen Bereich aufweisen

Cultural relativism and the discourse of intercultural communication: aporias of praxis in the intercultural public sphere

The premise of much intercultural communication pedagogy and research is to educate people from different cultures towards open and transformative positions of mutual understanding and respect. This discourse in the instance of its articulation realises and sustains Intercultural Communication epistemologically – as an academic field of social enquiry, and judgementally – as one which locates itself on a moral terrain. By adopting an ethical stance towards difference, the discourse of intercultural communication finds itself caught in a series of aporias, or performative contradictions, where interculturalists are projected simultaneously into positions of cultural relativism on the one hand and ideological totalism on the other. Such aporias arise because the theoretical premises upon which the discourse relies are problematic. We trace these thematics to a politics of presence operating within the discourse of intercultural communication and links this to questions of judgement and truth in the intercultural public sphere. We propose that the politics of presence be set aside in favour of an intercultural praxis which is oriented to responsibility rather than to truth

“Now he sings”. The My Musical Memories Reminiscence Programme: Personalised Interactive Reminiscence Sessions for People Living With Dementia

This paper explores the impact of the My Musical Memories Reminiscence Programme (MMMRP), an innovative intervention that adopts a music-based reminiscence approach. MMMRP builds on the format of the popular Singing for the Brain sessions with the aim of increasing opportunities for interaction and reminiscence among people living with dementia. Data were collected pre- and post-intervention and three months later using structured observation, interviews and focus groups. Results suggest that that programme had a positive impact on participants by promoting engagement, reminiscence and social interaction. For some individuals the impacts continued beyond their participation in the programme. A range of key facilitators for successful implementation of this approach were identified including the Session Leader role, the involvement of informal carers and the input of volunteers

Fitness costs of disrupting circadian rhythms in malaria parasites

Circadian biology assumes that biological rhythms maximize fitness by enabling organisms to coordinate with their environment. Despite circadian clocks being such a widespread phenomenon, demonstrating the fitness benefits of temporal coordination is challenging and such studies are rare. Here, we tested the consequences—for parasites—of being temporally mismatched to host circadian rhythms using the rodent malaria parasite, Plasmodium chabaudi. The cyclical nature of malaria infections is well known, as the cell cycles across parasite species last a multiple of approximately 24 h, but the evolutionary explanations for periodicity are poorly understood. We demonstrate that perturbation of parasite rhythms results in a twofold cost to the production of replicating and transmission stages. Thus, synchronization with host rhythms influences in-host survival and between-host transmission potential, revealing a role for circadian rhythms in the evolution of host–parasite interactions. More generally, our results provide a demonstration of the adaptive value of circadian rhythms and the utility of using an evolutionary framework to understand parasite traits

A possible role for Phlebotomus (Anaphlebotomus) rodhaini (Parrot, 1930) in transmission of Leishmania donovani

<p>Abstract</p> <p>Background</p> <p>Visceral leishmaniasis (VL, kala azar), caused by <it>Leishmania donovani </it>is a major health problem in Sudan and other East African countries. In this region the only proven vectors of <it>L. donovani </it>are <it>Phlebotomus orientalis </it>in eastern Sudan, Ethiopia and Upper Nile areas of Southern Sudan and <it>Phlebotomus martini </it>in Ethiopia, Kenya and Southern Sudan. In this report, we present the first evidence that <it>Phlebotomus rodhaini </it>may also play a role in maintaining transmission of <it>L. donovani </it>between animal reservoir hosts in eastern Sudan. The study was conducted in a zoonotic focus of visceral leishmaniasis in Dinder National Park, eastern Sudan, where previous work showed high infection rates of <it>L. donovani </it>in <it>P. orientalis</it>. Sand flies, captured by CDC traps were dissected and examined for infection with <it>Leishmania </it>parasites. Parasite isolates were subjected to <it>L. donovani </it>specific PCR. Field experiments were also carried out to compare efficiency of rodent baited and un-baited CDC traps in collection of <it>P. rodhaini </it>and determine its man-biting rate.</p> <p>Results</p> <p>Three female <it>P. rodhain</it>i were found infected with <it>Leishmania </it>parasites in an astonishingly small number of flies captured in three separate field trips. Two of these isolates were typed by molecular methods as <it>L. donovani</it>, while the third isolate was inoculated into a hamster that was subsequently lost. Although <it>P. rodhaini is </it>generally considered a rare species, results obtained in this study indicate that it can readily be captured by rodent-baited traps. Results of human landing collection showed that it rarely bites humans in the area.</p> <p>Conclusion</p> <p>It is concluded that <it>P. rodhaini </it>is a possible vector of <it>L. donovani </it>between animal reservoir hosts but is not responsible for infecting humans. It is suggested that the role of <it>P</it>. <it>rodhaini </it>in transmission of <it>L. donovani </it>in other zoonotic foci of visceral leishmaniasis in Africa should be re-examined.</p

Out of resistance comes strength: A Multi-Phased Fidelity Study of an Equipment-Based Resistance Program for Older Adults

Purpose: Within the US, people are experiencing longer life expectancy, yet these extended lifespans have not necessarily translated into years living in good health. Research shows that regular resistance exercise carries distinct preventive health benefits for older adults. The purpose of this research is to conduct a multi-phased study to evaluate the fidelity of an equipment-based resistance training program designed specifically for older adults. Methods: A three-phased study has been designed. Phase 1 consisted of a systematic literature review to identify salient measures of internal and external validity for equipment-based resistance training programs for older adults. Phase 2 is a pilot study at one location with 10 participants. The Senior Fitness Test and a pre-post survey are being used to measure the physical function and quality of life outcomes of the program. Four dimensions of internal validity (adherence, exposure, quality of delivery, and participant responsiveness) are being measured via seven observational tools, pre-post surveys, and post-program focus groups. These observational tools include a session checklist, teacher movement analysis, demonstration analysis, instructor feedback analysis, a system for observing fitness instruction time (SOFIT), and time analysis. Phase 3 scales up the evaluation program to 5 locations. Measures utilized in Phase 3 will be informed by the results of the pilot study. Results: Our paper presents the pilot evaluation protocol. By the end of the pilot, we will evaluate the degree of internal validity, estimate the effect on physical function and quality of life outcomes, and present program feedback from instructors and participants. Conclusions: The anticipated outcomes of the study will inform the implementation of equipment-based resistance training programs with older adults
