Communities of practice in residential aged care: A rapid review.

Communities of practice (CoPs) have the potential to help address the residential aged care system's need for continuing education and quality improvement. CoPs have been used in healthcare to improve clinical practice; however, little is known about their application to the unique residential aged care context. This rapid review of CoPs for residential aged care was conducted to summarise the features of CoPs, how they are developed and maintained, and assess their effectiveness. MEDLINE and CINAHL databases were searched for studies published from January 1991 to November 2022 about CoPs in residential aged care. Data were extracted regarding the CoPs' three key features of 'domain', 'community' and 'practice' as described by Wenger and colleagues. Kirkpatrick's four levels of evaluation (members' reactions, learning, behaviour and results) was used to examine studies on the effectiveness of CoPs. The Mixed Methods Appraisal Tool was used for quality appraisal. Nineteen articles reported on 13 residential aged care CoPs. Most CoPs aimed to improve care quality (n = 9, 69%) while others aimed to educate members (n = 3, 23%). Membership was often multidisciplinary (n = 8, 62%), and interactions were in-person (n = 6, 46%), online (n = 3, 23%) or both (n = 4, 31%). Some CoPs were developed with the aid of a planning group (n = 4, 31%) or as part of a larger collaborative (n = 4, 31%), and were maintained using a facilitator (n = 7, 54%) or adapted to member feedback (n = 2, 15%). Thirteen (81%) studies evaluated members' reactions, and three (24%) studies assessed members' behaviour. The heterogeneity of studies and levels of reporting made it difficult to synthesise findings. This review revealed the variation in why, and how, CoPs have been used in residential aged care, which is consistent with previous reviews of CoPs in healthcare. While these findings can inform the development of CoPs in this context, further research is needed to understand how CoPs, including the membership makeup, delivery mode, facilitator type and frequency of meetings, impact quality of care.

Diversity, Unity, and Global Citizenship Education: A Case Study in Community Outreach Program in Indonesia

Community Outreach Program is an established international service-learning program which has been around for 22 yr. The program offers an inter-discipline activity set in an international atmosphere to connect the academic theories with the actual social life and problems in the less developed rural community in East Java Province, Indonesia. There have been students from 16 university partners from 10 different countries ever participating in the program. Studies from the observations and opinions by the university partners claimed that COP has had an impactful outcomes in students‟ learning in the areas of diversity awareness, citizenship, and values development. The first study in 2009 on students‟ expectations in participating in COP reported that the students were aware that joining COP would expose them in diversity through working along with international friends and the community in the village. In this current study, 90 reflection books of COP 2015 Asian participants from Japan, Hong Kong, South Korea, and Indonesia were further studied to test and evaluate how COP as a service-learning program has provided an education setting to educate caring and responsible citizens, who were open to other cultures, and respectful of differences. Students' responses affirmed the positive effects of COP on the acceptance of diversity and sense of civic responsibility.

Organizational communities of practice: Review, analysis, and role of information and communications technologies

ABSTRACTInformation and communications technologies (ICTs) play a key role in supporting Communities of Practice (CoPs). A review of the extant literature reveals six factors that facilitate or constrain the development, sustenance, and effectiveness of CoPs that, in turn, enable generative and degenerative structures and behaviors that affect epistemic environments within Organizational Communities of Practice (orgCoPs). OrgCoPs are accepted as beneficial organizational learning structures and need to be deliberately designed and cultivated. The materiality of ICTs that is used to support orgCoPs may play a role in supporting or opposing seeding structures. The literature review further reveals five material properties that describe the relationship between the orgCoPs and the technologies used to support it. We argue that these distinct but intersecting properties are germane to understanding the role that ICTs play in supporting orgCoPs and propose that the future work on orgCoPs could be nuanced if examined through the lens of ICTs’ materiality.

Continuous vapour adsorption cooling system with three adsorber beds

In this paper, the design of a new solar operated adsorption cooling system with two identical small and one large adsorber beds, which is capable of producing cold continuously, has been proposed. In this system, cold energy is stored in the form of refrigerant in a separate refrigerant storage tank at ambient temperature. Silica gel–water is used as a working pair and system is driven by solar energy. The operating principle is described in details and its thermodynamic transient analysis is presented. Effect of COP and SCE for different adsorbent mass and adsorption/desorption time of smaller beds are discussed. Recommended mass and number of cycles of operation for smaller beds to attain continuous cooling with average COP and SCE of 0.63 and 337.5 kJ/kg, respectively are also discussed, at a generation, condenser and evaporator temperatures of 368 K, 303 K and 283 K, respectively.

Evaluating communities of practice and knowledge networks: a systematic scoping review of evaluation frameworks.

Communities of Practice (CoPs) are increasingly considered a part of ecohealth and other sectors such as health care, education, and business. However, there is little agreement on approaches to evaluate the influence and effectiveness of CoPs. The purpose of this review was to understand what frameworks and methods have been proposed or used to evaluate CoPs and/or knowledge networks. The review searched electronic databases in interdisciplinary, health, education, and business fields, and further collected references and forward citations from relevant articles. Nineteen articles with 16 frameworks were included in the synthesis. The purposes of the evaluation frameworks varied; while some focused on assessing the performance of CoPs, several frameworks sought to learn about CoPs and their critical success factors. Nine of the frameworks had been applied or tested in some way, most frequently to guide a case study. With limited applications of the frameworks, strong claims about generalizability could not be made. The review results can inform the development of tailored frameworks. However, there is a need for more detailed and targeted CoP evaluation frameworks, as many imperative CoP evaluation needs would be unmet by the available frameworks.

Research on the Mechanism of Energy-Saving Technology Innovation in Energy Service Companies

This paper analyzed the moderating effect of COP’s identity and COP’s competition between network structure of COP and energy-saving technology innovation. The empirical analysis illustrates that the relationship between the COP’s relation strength and energy-saving technology innovation is fully mediated by COP’s identity and COP’s competition, and the relationship between the COP’s status disparity and energy-saving technology innovation is partly mediated by COP’s identity and COP’s competition.

Use of communities of practice in business and health care sectors: A systematic review

BackgroundSince being identified as a concept for understanding knowledge sharing, management, and creation, communities of practice (CoPs) have become increasingly popular within the health sector. The CoP concept has been used in the business sector for over 20 years, but the use of CoPs in the health sector has been limited in comparison.ObjectivesFirst, we examined how CoPs were defined and used in these two sectors. Second, we evaluated the evidence of effectiveness on the health sector CoPs for improving the uptake of best practices and mentoring new practitioners.MethodsWe conducted a search of electronic databases in the business, health, and education sectors, and a hand search of key journals for primary studies on CoP groups. Our research synthesis for the first objective focused on three areas: the authors' interpretations of the CoP concept, the key characteristics of CoP groups, and the common elements of CoP groups. To examine the evidence on the effectiveness of CoPs in the health sector, we identified articles that evaluated CoPs for improving health professional performance, health care organizational performance, professional mentoring, and/or patient outcome; and used experimental, quasi-experimental, or observational designs.ResultsThe structure of CoP groups varied greatly, ranging from voluntary informal networks to work-supported formal education sessions, and from apprentice training to multidisciplinary, multi-site project teams. Four characteristics were identified from CoP groups: social interaction among members, knowledge sharing, knowledge creation, and identity building; however, these were not consistently present in all CoPs. There was also a lack of clarity in the responsibilities of CoP facilitators and how power dynamics should be handled within a CoP group. We did not find any paper in the health sector that met the eligibility criteria for the quantitative analysis, and so the effectiveness of CoP in this sector remained unclear.ConclusionThere is no dominant trend in how the CoP concept is operationalized in the business and health sectors; hence, it is challenging to define the parameters of CoP groups. This may be one of the reasons for the lack of studies on the effectiveness of CoPs in the health sector. In order to improve the usefulness of the CoP concept in the development of groups and teams, further research will be needed to clarify the extent to which the four characteristics of CoPs are present in the mature and emergent groups, the expectations of facilitators and other participants, and the power relationship within CoPs.

Copolymer 1 inhibits manifestations of graft rejection.

Copolymer 1 (Cop 1) was previously shown to prevent graft-versus-host disease and interfere in various manifestations of immune rejection. In this study, we tested whether Cop 1 can also hinder the reactivity of host against graft and inhibit graft rejection. Cop 1 was tested in two transplantation systems: skin and thyroid grafting assays. The effect of Cop 1 on T cell reactivity was investigated by proliferation and cytokine secretion of spleen and lymph node cells from transplanted mice, as well as the T cell lines generated therefrom. Cop 1 treatment prolonged skin graft survival and inhibited the functional deterioration of thyroid grafts, in various strain combinations, across minor and major histocompatibility barriers, similarly to the potent immunosuppressive drug FK506. Cop 1 inhibited the proliferation of graft-specific T cell lines, as well as their interleukin (IL)-2 and interferon-gamma (IFN-gamma) secretion, when incubated in vitro with the stimulating allogeneic cells. Spleen and lymph node cells from Cop 1-treated mice, as well as the T cell lines generated from them, demonstrated a pronounced inhibition of proliferation and secretion of T helper (Th)1 cytokines in response to graft cells. In addition, cells from Cop 1-treated mice secreted high amounts of Th2 cytokines in response to Cop 1 and small but significant amounts of Th2 cytokines, mainly IL-10, in response to allograft cells. Cop 1 treatment inhibited the Th1 response to graft and induced a Th2 cytokines secretion in response to both Cop 1 and graft cells, leading to improved survival and function of the transplanted grafts.

The Concept of Specific Immune Treatment Against Autoimmune Diseases

Copolymer 1 (Cop 1, Copaxone®) is a synthetic ammo acid copolymer effective in suppression of experimental allergic encephalomyelitis (EAE). The suppressive effect of Cop 1 in EAE is not restricted to a certain species, disease type or encephalitogen used for EAE induction. In phases II and III clinical trials Cop 1 was found to slow progression of disability and reduce the relapse rate in exacerbating-remitting multiple sclerosis (MS) patients.To extend this concept we have more recently shown that a similar approach is possible in the case of myasthenia gravis. We used two myasthenogenic T cell epitopes of the human acetylcholine receptor α-subunit and demonstrated that they are capable of triggering peripheral blood lymphocytes of the majority (> 80%) of myasthenic patients tested. Both single amino acid analogs, and a dual analog composed of the tandemly arranged two single amino acid analogs were able to inhibit in vitro proliferative responses of T cell lines, and in vivo priming of lymph node cells. The dual analog inhibited experimental autoimmune myasthenia gravis even when the mice were treated fourteen days after the injection of the pathogenic T cell line.

Weight loss in rats treated with intracerebroventricular cobalt protoporphyrin is not specific to the neuropeptide Y system

Cobalt protoporphyrin (CoPP) reduces food intake and body weight following intracerebroventricular (i.c.v.) administration in rats. We injected 0.2 μmol CoPP per kg body weight i.c.v. and monitored body weight and daily food intake for 7 days. The body weight and 24 h food intake of CoPP-treated animals was significantly lower than that of vehicle-treated animals in all studies ( P < 0.01) from day 2 to day 7. The 2 h feeding response (CoPP vs. vehicle-treated) to 10 μg neuropeptide Y (NPY) (4.0 vs. 7.1 g; P < 0.05), the 1 h feeding response to 10 μg galanin (1.3 vs. 3.2 g; P < 0.05) and 30 μg norepinephrine (0.6 vs. 1.9 g; P < 0.05) in CoPP-treated animals were all reduced compared to the vehicle-treated group. In addition there was no change in hypothalamic NPY mRNA in CoPP-treated animals. I.c.v. COP decreases sensitivity to exogenous NPY, galanin and norepinephrine. The effect of COP is not specific to NPY as previously described.

The effect of Cop 1, a synthetic polypeptide, on chronic relapsing experimental allergic encephalomyelitis in guinea pigs

Cop 1, a synthetic polypeptide, was evaluated for its effect on a chronic relapsing form of experimental allergic encephalomyelitis (EAE). Pretreatment of juvenile Strain 13 guinea pigs with Cop 1 in incomplete Freund's adjuvant (IFA) which were subsequently challenged with guinea pig spinal cord in complete Freund's adjuvant (CFA) had a marked effect in delaying or preventing the appearance of clinical signs of EAE. Administration of Cop 1 on appearance of clinical signs of EAE prevented progression of the first episode of the disease. Although relapses were not always prevented, they were modified in their duration and intensity both clinically and histologically.
