Experiences are at the core of tourism and hospitality. Understanding how to design, manage and measure such experiences has become a key topic in academic literature focused on this sector. This paper presents the characteristics of an optimal design process model for experiences, based on the results of a meta-ethnographic synthesis of such processes. The characteristics can be seen as critical success factors in delivering the right solution to the right problem efficiently and effectively. Depending on the context, starting level and aim of the design, designers can benefit from applying several different design processes. Such a process benefits from design capabilities developed in multi-disciplinary teams. Moreover, the design process aids design teams through steering the collection of explicit and tacit knowledge on problem and solution aspects with stakeholders in a specific order. The success of a design process depends on procedural knowledge of lead designers and their ability to orchestrate and integrate contributions from various disciplines and stakeholders at the right times. Existing design processes for tourism and hospitality experiences lack maturity and flexibility, resulting in them having poor structural validity. However these processes, with insights from design science, can form a base for further theoretical development.

Problems of energy security, diversification of energy sources, and improvement of technologies (including alternatives) for obtaining motor fuels have become a priority of science and practice today. Many scientists devote their scientific research to the problems of obtaining effective brands of alternative (reformulated) motor fuels. Our scientific school also deals with the problems of the rational use of traditional and alternative motor fuels.This article focused on advances in motor fuel synthesis using natural, associated, or biogas. Different raw materials are used for GTL technology: biomass, natural and associated petroleum gases. Modern approaches to feed gas purification, development of Gas-to-Liquid-technology based on Fischer–Tropsch synthesis, and liquid hydrocarbon mixture reforming are considered.Biological gas is produced in the process of decomposition of waste (manure, straw, grain, sawdust waste), sludge, and organic household waste by cellulosic anaerobic organisms with the participation of methane fermentation bacteria. When 1 tonne of organic matter decomposes, 250 to 500–600 cubic meters of biogas is produced. Experts of the Bioenergy Association of Ukraine estimate the volume of its production at 7.8 billion cubic meters per year. This is 25% of the total consumption of natural gas in Ukraine. This is a significant raw material potential for obtaining liquid hydrocarbons for components of motor fuels.We believe that the potential for gas-to-liquid synthetic motor fuels is associated with shale and coalfield gases (e.g. mine methane), methane hydrate, and biogas from biomass and household waste gases.

Inhibition of the sodium−glucose cotransporter 2 (SGLT2) by canagliflozin in type 2 diabetes mellitus results in large between-patient variability in clinical response. To better understand this variability, the positron emission tomography (PET) tracer [18F]canagliflozin was developed via a Cu-mediated 18F-fluorination of its boronic ester precursor with a radiochemical yield of 2.0 ± 1.9% and a purity of >95%. The GMP automated synthesis originated [18F]canagliflozin with a yield of 0.5−3% (n = 4) and a purity of >95%. Autoradiography showed [18F]canagliflozin binding in human kidney sections containing SGLT2. Since [18F]canagliflozin is the isotopologue of the extensively characterized drug canagliflozin and thus shares its toxicological and pharmacological characteristics, it enables its immediate use in patients.

Background: Peer review is at the heart of the scientific process. With the advent of digitisation, journals started to offer electronic articles or publishing online only. A new philosophy regarding the peer review process found its way into academia: the open peer review. Open peer review as practiced by BioMed Central (BMC) is a type of peer review where the names of authors and reviewers are disclosed and reviewer comments are published alongside the article. A number of articles have been published to assess peer reviews using quantitative research. However, no studies exist that used qualitative methods to analyse the content of reviewers’ comments. Methods: A focused mapping review and synthesis (FMRS) was undertaken of manuscripts reporting qualitative research submitted to BMC open access journals from 1 January – 31 March 2018. Free-text reviewer comments were extracted from peer review reports using a 77-item classification system organised according to three key dimensions that represented common themes and sub-themes. A two stage analysis process was employed. First, frequency counts were undertaken that allowed revealing patterns across themes/sub-themes. Second, thematic analysis was conducted on selected themes of the narrative portion of reviewer reports. Results: A total of 107 manuscripts submitted to nine open-access journals were included in the FMRS. The frequency analysis revealed that among the 30 most frequently employed themes “writing criteria” (dimension II) is the top ranking theme, followed by comments in relation to the “methods” (dimension I). Besides that, some results suggest an underlying quantitative mindset of reviewers. Results are compared and contrasted in relation to established reporting guidelines for qualitative research to inform reviewers and authors of frequent feedback offered to enhance the quality of manuscripts. Conclusions: This FMRS has highlighted some important issues that hold lessons for authors, reviewers and editors. We suggest modifying the current reporting guidelines by including a further item called “Degree of data transformation” to prompt authors and reviewers to make a judgment about the appropriateness of the degree of data transformation in relation to the chosen analysis method. Besides, we suggest that completion of a reporting checklist on submission becomes a requirement.

Little has been published regarding the training of academic developers themselves to support internationalization of the curriculum (IoC) initiatives. However, higher education institutions around the globe are responding to strategic demands for IoC which prepare students as ‘world-ready’ graduates. We employed qualitative research synthesis to identify recent journal articles which consider current trends in academic development to support IoC. Despite their diversity, we found common themes in the five selected studies. Our discussion and recommendations weave these themes with Betty Leask’s five-stage model of the process of IoC and Cynthia Joseph’s call for a pedagogy of social justice. “This is an Accepted Manuscript of an article published by Taylor & Francis in International Journal for Academic Development on 19/11/15, available online: https://doi.org/10.1080/1360144X.2019.1691559.

Background: Acne vulgaris is a multifaceted skin disorder, affecting more than 85% of young individuals worldwide. Pharmacological therapy is not always desirable because of the development of antibiotic resistance or the potential risk of adverse effects. Non‐pharmacological therapies can be viable alternatives for conventional therapies. However, sufficient evidence‐based support in the efficacy and safety of non‐pharmacological therapies is lacking. Objective: To assess the efficacy and safety of several non‐pharmacological therapies in the treatment of acne vulgaris. Methods: A systematic literature review, including a best‐evidence synthesis, was performed to identify literature. Three electronic databases were accessed and searched for studies published between January 2000 and May 2017. Results: Thirty‐three eligible studies were included in our systematic review. Three main types of non‐pharmacological therapies were identified laser‐ and light‐based therapies, chemical peels and fractional microneedling radiofrequency. The majority of the included studies demonstrated a significant reduction in acne lesions. However, only seven studies had a high methodologic quality. Based on these seven trials, a best‐evidence synthesis was conducted. Strong evidence was found for glycolic acid (10–40%). Moderate evidence was found for amino fruit acid (20–60%), intense pulsed light (400–700 and 870–1200 nm) and the diode laser (1450 nm). Initially, conflicting evidence was found for pulsed dye laser (585–595 nm). The most frequently reported side‐effects for non‐pharmacological therapies included erythema, tolerable pain, purpura, oedema and a few cases of hyperpigmentation, which were in most cases mild and transient. Conclusion: Circumstantial evidence was found for non‐pharmacological therapies in the treatment of acne vulgaris. However, the lack of high methodological quality among included studies prevented us to draw clear conclusions, regarding a stepwise approach. Nevertheless, our systematic review including a best‐evidence synthesis did create order and structure in resulting outcomes in which a first step towards future research is generated.

Granular 2-nitropropyl potato starch was synthesized by reaction with 2-nitropropyl acetate in an aqueous suspension. Nitroalkylation occurs preferentially with the amylose fraction of potato starch, as was confirmed by leaching experiments and digestion of the modified starch with α-amylase. The 2-nitropropyl substituent is a mixture of the nitroalkane and nitronic acid tautomer. Some grafting occurs and to a lesser extent additional reactions (formation of carbonyls and oximes) of the nitro group take place. After catalytic hydrogenation of water soluble 2-nitropropyl starch only a small amount of the nitro functionality was reduced to the corresponding amine. Reduction of granular 2-nitropropyl starch with sodium dithionite did not go to completion and led to a complex mixture of starting material, several intermediates and side products (for example sulfamates). © 2001 Elsevier Science Ltd.

The synthesis of total cellular proteins in Escherichia coli K12 was studied in batch culture following exposure of cells to low concentrations of monochlorophenol, pentachlorophenol and cadmium chloride. Changes in protein patterns were identified after pulse-chase labelling of proteins with [35S]methionine and subsequent two-dimensional gel electrophoresis (2D-PAGE). We demonstrated that besides the induction of some stress proteins, also a transient decrease in the rate of synthesis of other proteins occurred. Two of these proteins were identified as OmpF and aspartate transcarbamoylase (ATCase). Their transient repression appeared to be a general response to stress elicited by different pollutants and may therefore be used as a general and sensitive early warning system for pollutant stress.

BACKGROUND: Consideration of older adults' quality of life (QoL) is becoming increasingly important in the evaluation, quality improvement and allocation of health and social care services. While numerous definitions and theories of QoL have been proposed, an overall synthesis of the perspective of older adults themselves is lacking.METHODS: Qualitative studies were identified in PubMed, Ebsco/Psycinfo and Ebsco/CINAHL, through a search on 28 November 2018. Articles needed to meet all of the following criteria: (i) focus on perceptions of QoL, (ii) older adults living at home as main participants, (iii) use of qualitative methodology, (iv) conducted in a Western country and (v) published in English (vi) not focused on specific patient groups. A thematic synthesis was conducted of the selected studies, using the complete 'findings/results' sections from the papers.RESULTS: We included 48 qualitative studies representing the views of more than 3,400 older adults living at home in 11 Western countries. The QoL aspects identified in the synthesis were categorized into nine QoL domains: autonomy, role and activity, health perception, relationships, attitude and adaptation, emotional comfort, spirituality, home and neighbourhood, and financial security. The results showed that although different domains can be distinguished, these are also strongly connected.CONCLUSION: QoL can be expressed in a number of domains and related subthemes that are important for older adults living at home. The findings further support that the concept of QoL should be seen as a dynamic web of intertwined domains.

While luxury accommodation experience research has increased in the last decade, the field shows little accumulation of knowledge over time, requiring further foundational development. This study presents a meta-ethnographic synthesis of sixteen qualitative studies to propose a new conceptualisation of the luxury accommodation experience. The study follows Noblit and Hare (1988) seven-steps methodology for the interpretative synthesis of qualitative empirical studies, an under-utilised methodology introduced by Smit, Melissen, Font, and Gkritzali (2020) in tourism and hospitality research. The synthesis model highlights the emotional, multi-dimensional and process-driven nature of the luxury accommodation experiences, created by guests, hosts, and external others through the social interaction occurring within a physical and sensorial environment and influenced by personal and situational factors. The synthesis also underlines three factors characterising the luxury accommodation experience, congruence, culture, and collaboration, providing a foundational framework to advance hospitality luxury experience research. Implications for practitioners are also highlighted.
