Authors: Konstantinidis Christos , Aggelopoulos Stamatis , Tsiouni Maria , Rizopoulou Evanthia 
Published: June 2021

PurposeThe objective of this study is to estimate the competitiveness for both the Greek food and beverage industry as a whole and the flour and milling industry, justifying the certain economic factors and the way which these factors affect on it.Design/methodology/approachThe Greek food and beverage firms which published their balance sheets for the studying period were studied. According to the existing literature two equations were created and estimated as a simultaneous equations system.FindingsSummarizing the results both for the whole food and beverage industry and the flour milling industry are observed significant similarities on how certain economics factors such as profitability, market share, sustainable growth, age and operating costs affect on competitiveness as measured in this work. This may happen due to the high degree of concentration but also in the special characteristics which present both the Greek food and beverage industry and the flour milling sector.Research limitations/implicationsThe fact that this work referred only in Greek firms can be a limitation of this research, in spite of that it can provide useful and safe conclusions for the Greek food manufacturing industry.Practical implicationsThe provision of proposals for increasing firm competitiveness to managers as well as to policymakers.Social implicationsThe importance of food and beverage industry for the Greek economy as well as that the flour milling industry holds an important position in the Greek food and beverage industry makes the study of the competitiveness for both of them to be important from both an academic and research perspective.Originality/valueThe Greek food and beverage industry is the strength of Greek manufacturing and at the same time an important lever for the development of the entire Greek economy. The high quality products it produces and the organized promotion of its products in international markets are elements that give it an advantage and stimulate its competitiveness. The flour milling industry is one of the sectors in which there is intense competition and whose presence in terms of sales, turnover, employment and gross value is particularly important, so a simultaneous study of these cases is very important.

Published: June 2021

PurposeIn the literature of industrial management, the focus is normally given on examining the factors that contribute to product innovation acceptance. The advocates of “pro-innovation bias” assume that consumers are open to new products and are willing to accept an innovative product. However, there is a high failure rate of technological innovations and most of the technological innovations were rejected due to users' resistance. Since the inception of innovation resistance theory (IRT), the number of studies that used IRT has gained much attention from scholars. However, the findings from these studies from various contexts are inconsistent, lack universality, and a clear understanding of technological innovation barriers. The study aims to determine whether the IRT theory is indeed valid and whether IRT is culturally invariant from the Eastern and Western cultures.Design/methodology/approachA meta-analysis based on a random-effects model and studies drawn from 24 countries and/or regions with a consolidated sample size of 10,463 was conducted. Cultural invariance was identified based on subgroup analysis. Moderator analysis was performed by applying the weighted linear regression.FindingsThe results reveal that tradition is the strongest barrier followed by the value, risk, image and usage barrier. Interestingly, there is a cultural invariance in IRT from the Eastern and Western cultures. Besides, there are significant moderating effects due to the temporal factor.Originality/valueThe study has contributed useful theoretical and managerial implications in advancing the product innovation literature.

Published: June 2021

PurposeThis paper aims to study the evolution of definitions of internet of things (IoT) through time, critically assess the knowledge these definitions contain and facilitate sensemaking by providing those unfamiliar with IoT with a theoretical definition and an extended framework.Design/methodology/approach164 articles published between 2005 and 2019 are collected using snowball sampling. Further, 100 unique definitions are identified in the sample. Definitions are examined using content analysis and applying a theoretical framework of five knowledge dimensions.FindingsIn declarative/relational dimensions of knowledge, increasing levels of agreement are observed in the sample. Sources of tautological reasoning are identified. In conditional and causal dimensions, definitions of IoT remain underdeveloped. In the former, potential limitations of IoT related to resource scarcity, privacy and security are overlooked. In the latter, three main loci of agreement are identified.Research limitations/implicationsThis study does not cover all published definitions of IoT. Some narratives may be omitted by our selection criteria and process.Practical implicationsThis study supports sensemaking of IoT. Main loci of agreement in definitions of IoT are identified. Avenues for further clarification and consensus are explored. A new framework that can facilitate further investigation and agreement is introduced.Originality/valueThis is, to the authors’ knowledge, the first study that examines the historical evolution of definitions of IoT vis-à-vis its technological features. This study introduces an updated framework to critically assess and compare definitions, identify ambiguities and resolve conflicts among different interpretations. The framework can be used to compare past and future definitions and help actors unfamiliar with IoT to make sense of it in a way to reduce adoption costs. It can also support researchers in studying early discussions of IoT.

Authors: Chitimira Howard 
Published: June 2021

Purpose
Insider trading is treated as a punishable offence in many jurisdictions and countries. In relation to this, various theories were developed to justify and enhance the regulation of insider trading in such jurisdictions and countries. For instance, regulatory bodies and the relevant courts in jurisdictions such as the Commonwealth and the European Union as well as in countries such as the USA and the UK have to date developed and consistently applied theories such as the classical theory, misappropriation theory, fiduciary theory, unified theory and equal access theory in their quest to detect, prevent and combat insider trading activities. For the purposes of this article, the aforesaid theories are discussed so as to recommend possible measures that could be adopted by the policy makers to effectively curb insider trading activities in the Zimbabwean financial markets. It is against this background that some theoretical aspects of the insider trading regulation as adopted by the Zimbabwean policymakers, regulatory bodies and the relevant courts are scrutinised in this paper. This is done to, inter alia, investigate possible flaws and the rationale for such direct and indirect application of certain insider trading theorem in Zimbabwe. Thereafter, some recommendations in respect thereof are provided.

Design/methodology/approach
A qualitative research methodology is used in the entire paper.

Findings
It is hoped that the recommendations in the paper will be used by the relevant policymakers to enhance the curbing of insider trading in Zimbabwe.

Research limitations/implications
The paper does not use an empirical research.

Practical implications
It is hoped that the recommendations in this paper will be used by the relevant policymakers to enhance the curbing of insider trading in Zimbabwe.

Social implications
It is hoped that the recommendations in this paper will be used by the relevant policymakers to enhance the curbing of insider trading in Zimbabwe.

Originality/value
This paper is original research on the theoretical aspects of the regulation of insider trading in Zimbabwe.

Published: June 2021

PurposeDietary patterns are important for the physical and psychological development of adolescents. The purpose of this study is to determine magnitude and severity of depression and its relation with diet diversity score (DDS) among adolescent high school students.Design/methodology/approachA cross-sectional study was conducted among 546 adolescents selected from schools using multistage sampling technique. Dietary intakes were assessed using a 24-h dietary recall, and depression severity and prevalence were assessed by PHQ-9A. A structured questionnaire was used to collect data. Linear regression analysis was used, and unstandardized beta (ß) coefficients with 95% confidence intervals (CI) were computed to determine the association of depression and its severity with dietary diversity score.FindingsIn all, 546 questionnaires were filled completely and consistently making a response rate of 97.3%. The dietary diversity score in 97 (17.8%) of the adolescents were between 1 and 3 (low dietary diversity score) but 259 (47.4%) scored greater than 6 (high dietary diversity score). Chi-square test revealed that with a decrease in DDS from highest to lowest level, the percentage of moderate to severe and severe depression slightly increased (3.4%). In addition, the percentage of moderate to severe and severe depression who consumed meat, fish and milk and dairy products slightly increased (3% and 3.2%). Multivariate adjusted regression analysis demonstrated that dietary diversity score was found to be inversely associated with depression severity and prevalence.Originality/valueIt was found that linear association between diet diversity and depression severity, and prevalence after adjustment for relevant con-founders. The study provided epidemiological evidence of a robust association of dietary pattern with depression symptoms' severity and prevalence in adolescents.

Authors: Cai Haiya , Nan Yongqing , Zhao Yongliang , Xiao Haoran 
Published: June 2021

PurposeThe purpose of this study is to regard winter heating as a quasi-natural experiment to identify the possible causal effects of winter heating on population mobility. However, there are scant research studies examining the effect of atmospheric quality on population mobility. There also exists some relevant research studies on the relationship between population mobility and environmental degradation (Lu et al., 2018; Reis et al., 2018; Shen et al., 2018), and these studies exist still some deficiencies.Design/methodology/approachThe notorious atmospheric quality problems caused by coal-fired heating in winter of northern China have an aroused widespread concern. However, the quantitative study on the effects on population mobility of winter heating is still rare. In this study, the authors regard the winter heating as a quasi-natural experiment, based on the of daily panel data of 58 cities of Tencent location Big Data in China from August 13 to December 30 in 2016 and August 16 to December 30 in 2017, and examine the impacts of winter heating on population mobility by utilizing a regression discontinuity method.FindingsThe findings are as follows, in general, winter heating significantly aggravates regional population mobility, but the impacts on population mobility among different cities are heterogeneous. Specifically, the effects of winter heating on population mobility is greater for cities with relatively good air quality, and the effects is also more obvious for big and medium-sized cities than that in small cities. In addition, different robustness tests, including continuity test, different bandwidth tests and alternative empirical model, are adopted to ensure the reliability of the conclusion. Finally, the authors put forward corresponding policy suggestions from the three dimensions of government, enterprises and residents.Originality/valueFirst, regarding winter heating as a quasi-natural experiment, a regression discontinuity design method is introduced to investigate the relationship between winter heating and population mobility, which is helpful to avoid the estimation error caused by endogeneity. Second, the authors use the passenger travel “big data” based on the website of Tencent Location Big Data, which can effectively capture the daily characteristics of China's population mobility. Third, this study discusses the population mobility from the perspective of winter heating and researches population mobility before and after winter heating, which is helpful in enriching the research on population mobility.

Published: June 2021

PurposeComprehensive management systems such as ISO 9001 or ISO 14001 are designed to help organizations improve processes, ensure customer satisfaction, efficient information flow, efficient use of resources and many other prosperous management areas. These systems can also bring unintended direct and indirect effects on organizations. In this study, the authors examine the environmental effects that the implementation of these management systems cause.Design/methodology/approachA survey-based methodology was used for this study, with textile organizations in three countries – Poland, Slovakia and the Czech Republic. The research focused on four areas related to environmental effects. The first area was the level of improvement of the organizations' environmental performance, which was examined by the methods of descriptive statistics. The second area was analyzing differences in environmental effects concerning the implementation of the systems using inferential statistics. The third area was the analysis of latent links between individual effects using factor analysis.FindingsThis study's insights shed some light on the benefits of implementing more, not fewer systems with benefits to organizations and entire industries with new possibilities for economic growth that do not have to come at the expense of the environment.Originality/valueOrganizations implementing management systems can realize dynamic benefits across a supply chain and within a manufacturing organization. Here the authors see an opportunity for ISO systems as a stepping stone to a more sustainable textile manufacturing economy.

PurposeThe purpose of this study is to explore the dimensional structure of visitor experience in a sacred place based on the framing process.Design/methodology/approachMix-method research was conducted in Turkey–Virgin Mary House which featured a sacred and popular tourist destination. Qualitative research, including interviews and expert panels, was used to create a set of knowledge for further analysis. Quantitative research, including two field studies comprising 842 participants, was used to validate the framing of visitor experiences in a sacred place providing reliability and construct validity.FindingsThe six dimensions were found within three framing axes of religious, environmental and organizational: inner experience; religious experience; physical environment; history; tour organization and service experience.Originality/valueCurrent studies on visitor experience in a sacred place have mainly focused on emotions, motivations or physical dimensions. By synthesising the framing process and theoretical approaches, this study contributes to the literature by analysing the unique characteristics of visitors' experiences in sacred places, regardless of their religious identities.
Investigating stakeholder awareness of the sustainable development goals and tourism stakeholder collaboration: the case of North Cyprus
Authors: Özgit Hale , Zhandildina Dana 
Published: June 2021

Purpose
The aim of the study is to consider the extent to which the 17 sustainable development goals (SDGs) agreed by United Nations member states contribute to sustainable tourism and to relevant targets in North Cyprus. The study also investigates how tourism stakeholders in North Cyprus understand and implement the UN’s SDGs.

Design/methodology/approach
A qualitative study with structured questions was used to investigate awareness of the UN SDGs and collaboration between 19 tourism stakeholders from different sectors (tour guides, hotels, travel agencies, restaurants and government) in North Cyprus.

Findings
The results of the study reveal that not all of the SDGs have been embraced in North Cyprus, and that there is lack of understanding about the goals and about the need for collaboration among the different tourism stakeholders in North Cyprus.

Practical implications
This study reveals many shortcomings in implementing sustainable tourism in North Cyprus. It would seem that only issues that affect financial performance are prioritised. At present, tourism stakeholders in North Cyprus do not collaborate and do not believe that collaboration would, in any way, influence the sustainability of tourism in the region or benefit them financially. Given this finding, stakeholder collaboration needs to be enhanced in support of tourism sustainability in North Cyprus, and in this, the government needs to act as a catalyst.

Originality/value
Many developing countries are trying to improve living conditions and, at the same time, protect the environment by implementing sustainable development initiatives. The most common initiatives include the creation of protected areas for tourism development. In this context, sustainable development targets for island economies such as North Cyprus are important.
Seismic erratic noise attenuation using unsupervised anomaly detection
Authors: Jeong Woodon , Almubarak Mohammed S. , Tsingas Constantinos 
Published: June 2021

ABSTRACTThis study introduces a new attribute to identify seismic erratic noise, i.e. outlier, in the context of unsupervised anomaly detection and is defined as local outlier probabilities. The local outlier probabilities calculate scores of degrees of isolation, i.e. outlier‐ness, for each object in a data set, which represents how far an object is deviated from its surrounding objects. Since the local outlier probabilities combines a density‐based outlier detection method with a statistically oriented scheme, its scoring system provides regularized outlier‐ness, which is an outlier probability, to be used for making a binary decision to do inclusion or exclusion of an object; such a decision only requires a simple and straightforward threshold on a probability. Based on the binary decision that flags outliers versus non‐outliers, local outlier probabilities‐denoising workflows are developed by combining multiple steps to complete an application of the local outlier probabilities to attenuate seismic erratic noise. Higher stability and improved robustness in the detection and rejection of seismic erratic noise have been achieved by implementing moving windows and decision tree‐based processes. To avoid loss of useful signal energy, signal enhancement applications are additionally suggested. Numerical experiments on synthetic data investigate the applicability of the proposed algorithms to seismic erratic noise attenuation. Field data examples demonstrate the feasibility of a local outlier probabilities‐denoising application as an effective tool in seismic denoising portfolio.
Bridging preference‐based instrumental variable studies and cluster‐randomized encouragement experiments: Study design, noncompliance, and average cluster effect ratio
Authors: Zhang Bo , Heng Siyu , MacKay Emily J. , Ye Ting 
Published: June 2021

AbstractInstrumental variable (IV) methods are widely used in medical research to draw causal conclusions when the treatment and outcome are confounded by unmeasured confounding variables. One important feature of such studies is that the IV is often applied at the cluster level, for example, hospitals' or physicians' preference for a certain treatment where each hospital or physician naturally defines a cluster. This paper proposes to embed such observational IV data into a cluster‐randomized encouragement experiment using nonbipartite matching. Potential outcomes and causal assumptions underpinning the design are formalized and examined. Testing procedures for two commonly used estimands, Fisher's sharp null hypothesis and the pooled effect ratio (PER), are extended to the current setting. We then introduce a novel cluster‐heterogeneous proportional treatment effect model and the relevant estimand: the average cluster effect ratio. This new estimand is advantageous over the structural parameter in a constant proportional treatment effect model in that it allows treatment heterogeneity, and is advantageous over the PER estimand in that it does not suffer from Simpson's paradox. We develop an asymptotically valid randomization‐based testing procedure for this new estimand based on solving a mixed‐integer quadratically constrained optimization problem. The proposed design and inferential methods are applied to a study of the effect of using transesophageal echocardiography during coronary artery bypass graft surgery on patients' 30‐day mortality rate. R package ivdesign implements the proposed method.
