Abstract

Purpose

This conceptual paper aims to explore government regulatory responses of social networking platforms (SNP) and tourism destination evangelism. This research draws on a two-phase data source review of government legislations that guarantee social media users and empirical papers related to social media platforms. The results revealed that Ghana has adopted specific legislations that manage and control SNP. To the best of the author’s knowledge, this study is the first of its kind that synthesized government legislation and empirical papers on social networking platforms in evangelising destinations which have been missing in extant literature.

Abstract

Purpose

While the literature has described social entrepreneurs as overwhelmingly occupying a pivotal role in social entrepreneurship (S-ENT) process, there is a high inconsistency prevailing with respect to entrepreneurial traits, attitudes and skills of social entrepreneurs. One explanation for this may be the lack of a suitable scale measuring entrepreneurship orientation of social entrepreneurial individuals. The purpose of this study is to address this gap by proposing an initial assessment tool for individual S-ENT orientation (ISEO).

Design/methodology/approach

A mixed methods research design, along with a two-stage Delphi process, helped in generating appropriate constructs for ISEO. While the items for the first dimension of scale were directly derived from the Delphi study, the items of the remaining dimensions were mainly found based on the three individual entrepreneurial orientation dimensions presented by Bolton and Lane. By means of exploratory factor analysis, the final examination of the ISEO items was undertaken through a survey of 71 social entrepreneurs across India. The process eventually resulted in reliable and valid measures for four dimensions of ISEO.

Findings

The scale-development process eventually resulted in a 13-item scale, measuring four dimensions of ISEO (social passion, innovativeness, risk-taking and pro-activeness). By developing a set of relevant ISEO indicators, the study answers the call for a scale development of ISEO in S-ENT literature.

Research limitations/implications

There is a need to further validate this instrument among other stakeholders (students) as well as in samples with different demographic characteristics across different regions of the country and the world. To further evaluate the reliability and validity properties and to confirm the newly established subscales and their relationship with the ISEO construct, there is need for conducting a confirmatory factor analysis using larger sample sizes.

Practical implications

The measurement of SEO at an individual level will assist in S-ENT education, training and development of present and prospective social entrepreneurs, as well as assist individuals who want to assess the strength of their orientation towards S-ENT. The understanding of ISEO at the individual level will be equally useful for S-ENT incubators, the government and other S-ENT stakeholders who are considering supporting S-ENT proposals.

Originality/value

The paper is the first to develop an ISEO scale which is based on empirical data in S-ENT field.

Abstract

In this paper we make an analysis of KOSPI 200 index options listed in Korea Stock and Futures Exchange whose trading volume is world best these days. We adopt the stochastic volatility model suggested by Heston (1993) for the dynamics of the underlying asset and use EMM to estimate the parameters of option pricing kernel. The SNP distribution of the implied volatility contains AR (2) and ARCH effects, and the skewness of the distribution is much higher than normal distribution. The distribution has thinner left tail and fatter right tail than normal distribution, which is opposite to the case of S&P 500 options market. The result of estimation shows that Implied volatility series of KOSPI 200 options have weak mean reverting property and are almost nonstationary. The correlation coefficient between the implied volatility and returns is estimated to have negligible negative number. These features are also opposite to the case of S&P 500 options market where implied volatility is reported to have strong mean reversion, and the correlation between the implied VIatilIty and retturns is reported to have large negative number.

Abstract

Purpose

During the 2014 independence referendum in Scotland, there was much debate about the future broader political direction of the country but little discussion about its impact on Scottish tourism. The purpose of this paper is to explore and discuss the impact of the different future political options from a tourism perspective.

Design/methodology/approach

From the literature, four main political drivers were identified, and using Scotland as a reference, they were used in discussions with six experts to explore how tourism could develop under different political options. The outcomes from these discussions were combined by the researcher to develop in conjunction with the experts an agreed discussion note. This discussion note formed the basis for the exploration of the impact on tourism under four different future political options.

Findings

Of the four political options (devolution limited, devolution plus, devolution max/fiscal autonomy/federation and full independence), it is clear that all options had different positive and negative impacts for tourism. The devolution max option, however, was perceived as most damaging to tourism, because tourism would not be considered a priority, relative to other policy issues. The study concludes with six key lessons that destination management organisations (DMOs) should contemplate when considering the impacts of different political futures.

Research limitations/implications

Being focussed on one country with a strong political party whose raison d'être is independence makes it difficult to extrapolate the results. Nevertheless, given the strong commonality of agreement of the impacts within the experts consulted, this study suggests that DMOs can and should engage in political debates about the future of tourism in their destination.

Originality/value

The 2014 independence referendum in Scotland failed to achieve its primary aim of independence for Scotland, but it did provide space for other political options to be explored. This paper provides a perspective on how tourism could develop under different political options, and so help raise its profile in any future debates, both in Scotland and other destinations.

Abstract

Purpose

Nicotine is consumed by one in five of the global adult population, mostly by smoking tobacco cigarettes. Modern electronic cigarettes came onto the market from around 2007 and have considerable potential to improve population health by displacing tobacco smoking. The purpose of this study is to map the use of e-cigarettes, but this is difficult due to absence of data sources for many countries.

Design/methodology/approach

The global number of vapers was estimated to be 68 million in 2020. New data in 2021 offered an opportunity to update that estimate. The method of assumed similarity was used for countries with missing data. The average prevalence of vaping was calculated for each World Health Organization region, World Bank income classification group and the legal status of e-cigarettes in each country. The number of vapers was calculated for the adult population. The estimate was refined by adjusting for changes in market value size and the actual year of surveys.

Findings

Population prevalence data on e-cigarette used were available for 48 countries. We estimate that there were 82 million vapers worldwide in 2021: 9.2 million in the Eastern Mediterranean region; 5.6 million in the African region; 20.1 million in the European region; 16.8 million in the Americas; 16.0 million in the Western Pacific region; and 14.3 million in South-East Asia.

Originality/value

Global, regional and national estimates of the numbers of vapers are important indicators of trends in nicotine use, and monitoring the uptake of vaping is important to inform international and national policy.

Abstract

Purpose

The purpose of this study had two aims: (1) to extend insight regarding the challenges of implementing standardised work, via care pathways, in a healthcare setting by considering interactions with other operational (i.e. resource sharing, portfolio alignment) and professional (i.e. autonomous expertise) dependencies and (2) to develop novel insights regarding a specific flow mechanism, the stroke nurse practitioner, a form of flow “pilo” or guide.

Design/methodology/approach

This was a longitudinal case study of implementing the acute stroke care pathway in a National Health Service hospital in England based on 185 hours of non-participant observations and 68 semi-structured interviews. Archival documents were also analysed.

Findings

The combined flow, operational and professional dependency lens extends operations management understanding of the challenge of implementing standardised work in healthcare. One observed practice, the process pilot role, may be particularly valuable in dealing with these dependencies but it requires specific design and continuous support, for which the authors provide some initial guidance.

Research limitations/implications

The research was a single case study and was focussed on a single care pathway. The findings require replication and extension but offer a novel set of insights into the implications of standardised work in healthcare.

Originality/value

In addition to confirming that a multidependency lens adds conceptual and practical insight to the challenges of implementing standardised work in a healthcare setting, the findings and recommendations regarding flow “pilots” are novel. The authors' analysis of this role reveals new insights regarding the need for continued improvisation in standardised work.

Abstract

Purpose

This scientific article aims to evaluate the efficacy of the drug Doxorubicin for treating hepatocellular carcinoma (HCC) in Egypt. The study analyzes data from patients referred to a multi-disciplinary consultation at the National Cancer Institute, Cairo University. The study includes 40 intermediate-stage HCC patients who underwent treatment with either Doxorubicin-Lipiodol or Doxorubicin-loaded drug-eluting beads-trans-arterial chemoembolization (DEB-TACE).

Design/methodology/approach

Patients referred to a multi-disciplinary consultation at the National Cancer Institute, Cairo University with a possible diagnosis of HCC in the intermediate stage were eligible for the study.

Findings

The study finds that the plasma peak concentration of Doxorubicin is significantly higher in patients treated with Lipiodol compared to those treated with DEB-TACE. The median plasma peak concentration of patients treated with Lipiodol was significantly higher 424 (202.5–731) than the peak level of patients treated with beads 84.95 (26.6–156.5) with p-value = 0.036. However, there is no significant difference in other pharmacokinetic parameters between the two treatment groups. The research article also investigates the genetic polymorphisms in HCC patients treated with Doxorubicin-Lipiodol and Doxorubicin-loaded DEB-TACE. It identifies a significant association between the ABCB1 gene (C3435T) and the concentration of Doxorubicin in plasma. Patients with the CCand computed tomography (CT) genotypes of ABCB1 have higher concentrations of Doxorubicin compared to those with the TT genotype. Furthermore, the study examines the progression-free survival rates and tumour response in the two treatment groups. It demonstrates that DEB-TACE patients have a higher progression-free survival rate compared to cTACE patients. DEB-TACE also leads to better tumour regression.

Originality/value

The current study helps to increase the understanding of the genetic factors that may contribute to HCC susceptibility in the Egyptian population. However, it is essential to consider that genetic polymorphism is just one aspect of HCC risk, and other factors such as environment, lifestyle and viral infections also play crucial roles. Further research is needed to elucidate the complex interactions between genetic and environmental factors in HCC development among Egyptians.

Abstract

Purpose

Process mining provides a generic collection of techniques to turn event data into valuable insights, improvement ideas, predictions, and recommendations. This paper uses spreadsheets as a metaphor to introduce process mining as an essential tool for data scientists and business analysts. The purpose of this paper is to illustrate that process mining can do with events what spreadsheets can do with numbers.

Design/methodology/approach

The paper discusses the main concepts in both spreadsheets and process mining. Using a concrete data set as a running example, the different types of process mining are explained. Where spreadsheets work with numbers, process mining starts from event data with the aim to analyze processes.

Findings

Differences and commonalities between spreadsheets and process mining are described. Unlike process mining tools like ProM, spreadsheets programs cannot be used to discover processes, check compliance, analyze bottlenecks, animate event data, and provide operational process support. Pointers to existing process mining tools and their functionality are given.

Practical implications

Event logs and operational processes can be found everywhere and process mining techniques are not limited to specific application domains. Comparable to spreadsheet software widely used in finance, production, sales, education, and sports, process mining software can be used in a broad range of organizations.

Originality/value

The paper provides an original view on process mining by relating it to the spreadsheets. The value of spreadsheet-like technology tailored toward the analysis of behavior rather than numbers is illustrated by the over 20 commercial process mining tools available today and the growing adoption in a variety of application domains.

Abstract

People with severe persistent mental illness pose a significant challenge to managed care organizations and society in general. The financial costs are staggering as is the community impact including homelessness and incarceration. This population also has a high incident of chronic comorbid disorders that not only drives up healthcare costs but also significantly shortens longevity. Traditional case management approaches are not always able to provide the intense and direct interventions required to adequately address the psychiatric, medical and social needs of this unique population. This article describes a Medicare Advantage Chronic Special Needs Program that provides a Medical Home, Active Community Treatment, and Integrated Care. A comparison of utilization and patient outcome measures of this program with fee for service Medicare found significant reduction in utilization and costs, as well as increased adherence to the management of chronic medical conditions and preventative services.

Abstract

Purpose

The authors investigate how COVID-19 has influenced the amount, type or topics of abuse that UK politicians receive when engaging with the public.

Design/methodology/approach

This work covers the first year of COVID-19 in the UK, from March 2020 to March 2021 and analyses Twitter abuse in replies to UK MPs. The authors collected and analysed 17.9 million reply tweets to the MPs. The authors present overall abuse levels during different key moments of the pandemic, analysing reactions to MPs by gender and the relationship between online abuse and topics such as Brexit, the government’s COVID-19 response and policies, and social issues.

Findings

The authors have found that abuse levels towards UK MPs were at an all-time high in December 2020. Women (particularly those from non-White backgrounds) receive unusual amounts of abuse, targeting their credibility and capacity to do their jobs. Similar to other large events like general elections and Brexit, COVID-19 has elevated abuse levels, at least temporarily.

Originality/value

Previous studies analysed abuse levels towards MPs in the run-up to the 2017 and 2019 UK General Elections and during the first four months of the COVID-19 pandemic in the UK. The authors compare previous findings with those of the first year of COVID-19, as the pandemic persisted, and Brexit was forthcoming. This research not only contributes to the longitudinal comparison of abuse trends against UK politicians but also presents new findings, corroborates, further clarifies and raises questions about the previous findings.
