Abstract

Purpose

The purpose of this paper is to investigate the superior relationship between blood lipid- and cardiovascular disease (CVD)-related hematological parameters using superior grey relational analysis (GRA).

Design/methodology/approach

A total of 294 individuals who underwent simultaneous routine blood examination and blood lipid examination in the Physical Examination Center of the First Affiliated Hospital of Shantou University Medical College were included in this study. Superior GRA was performed to find out the superior factor in CVD-related hematological parameters and blood lipids. CVD-related hematological parameters included red blood cell distribution width, white cell count, and platelet count, platelet distribution width, mean platelet volume, as well as platelet crit. The indicators of blood lipids analyzed here consist of low-density lipoprotein, high-density lipoprotein, triglyceride and total cholesterol.

Findings

The results showed that all the grey relational degree of hematological parameters and blood lipids were over 0.8; the superior factor in hematological parameters was PLT, whereas TC was the superior factor in blood lipids.

Practical implications

Findings of this study suggested that hematological parameters are closely related to blood lipids and a potential role for hematological parameters in the prediction of dyslipidemia, which need further study; TC has the greatest influence on hematological parameters, whereas TG displays a minimal impact.

Originality/value

To the authors’ best knowledge, it was the first study to analyze the relationship between various CVD-related hematological parameters and blood lipids via superior GRA.

Abstract

Purpose

The purpose of this paper is to construct a new algorithm of program procedure for medical grey relational method based on SAS software.

Design/methodology/approach

Based on the SAS environment, the authors construct a new algorithm of program procedure through the following methods: the construction data set, confirmation of the comparison sequence and reference sequence, the original data transformation, calculation of the grey relational coefficient of reference sequence and comparison sequence and calculating the correlation.

Findings

The results show that the novel algorithm of program procedure for medical grey relational method based on SAS software satisfies the properties properly. It also fully confirmed the biggest advantage of the grey relational analysis is that its requirements are not too high for the amount of data, and it does not need to follow the typical distribution.

Originality/value

The paper succeeds in constructing a novel algorithm of program procedures for medical grey relational method and providing a valuable tool for solving similar problems.

Abstract

Purpose

The purpose of this paper is to combine disaster risk reduction (DRR) and communication management literature to investigate the challenges and opportunities encountered when stakeholders spontaneously self-organise communication efforts during a disaster. The 2017 Knysna Fire Disaster in South Africa is used as the context.

Design/methodology/approach

The qualitative, exploratory research was supported by data obtained through thematic analysis of qualitative in-depth interviews and the Facebook page created by the community. Information from the disaster debrief was also included.

Findings

The findings suggest that disaster information needs to be sent every 30 s to a minute to coordinate rescue and relief efforts. The challenges for disaster management teams to manage this mammoth task and the role that the self-organising community played in assisting the communication process was found not to be recognised in disaster management policies or systems. This adversely affected the work of the disaster management team and stakeholder relationship.

Research limitations/implications

This study focussed on one disaster. Future studies could possibly compare various disaster examples to provide even greater insight into the self-organising communicative behaviour of those affected by disasters.

Originality/value

The research gives one of the first clear indications of the scope of disaster communication needed during a disaster. It also highlights the community’s ability to contribute to communication management during a disaster, and which is not catered for in the practice, guidelines or management systems used for disaster management.

Abstract

Red light districts have long been a traditional feature of many British cities, but the last two to three years has witnessed growing interest in and policy debate concerning the ways in which the state seeks to regulate the oldest profession. This short article offers a brief introduction to prostitution, focuses particularly on street prostitution and red light districts, and examines the arguments for and against the introduction of formally delimited ‘tolerance zones’ for prostitution. The article draws its illustrative material from the recent policy debates in Scotland and specifically from three Scottish cities, namely Aberdeen, Edinburgh and Glasgow.

Abstract

Purpose

The new teleworking conditions imposed by extreme events such as the COVID-19 pandemic blur the border between home and official working space, amplifying the conflicting demands of family and work life experienced by employees across national cultures. Drawing on conservation of resources (COR) theory, this study explores cross-national variances in the underlying mechanism of how family–work conflict (FWC) affects employees’ operational and marketing productivity in the global epidemic-induced teleworking context.

Design/methodology/approach

This study conducts a large-scale and cross-national survey of 710 remote employees who worked from home partially or fully during the COVID-19 outbreak across three countries: the USA, the UK and Vietnam.

Findings

The results show that FWC drives affective commitment, leading to greater employees’ operational and marketing productivity when teleworking. We also find distinct moderating effects of organizational factors (i.e. task control) and employees’ psychological factors (i.e. emotional exhaustion) on the FWC–operational productivity link across the three countries. Moreover, centralization positively moderates the effect of operational productivity on marketing productivity in the teleworking context in Vietnam, while it is not the case in the USA and the UK.

Originality/value

This study fills a gap in the literature by revealing cross-national differences in the underlying mechanism of the FWC effects on employees’ operational and marketing productivity in the pandemic-induced teleworking conditions. It extends extant studies in the work–family literature by introducing affective commitment as an important mediator in translating the negative consequences of FWC to operational and marketing productivity gain in crisis-driven teleworking across national cultures. We also provide insights into the distinct moderating roles of task control and emotional exhaustion in determining the FWC effect on operational productivity as well as that of centralization in driving marketing productivity. The findings have substantive implications for teleworking design and management to improve employee productivity across different national settings.

Abstract

In international marketing the search for suitable brand names is complicated by a number of issues. One of these is the decision as to whether to standardize, localize, or use some form of intermediate adapted strategy. In the case of the PR China, the situation is more complex still, owing to a number of factors, but, particularly because of its completely different logographic language structure. This paper examines several of the key issues in wine brand naming and then reports an empirical study into Chinese consumers' reactions to live different naming strategies, each applied to a selection of wine brands. The results indicated that the original foreign brand name was the most appealing whilst a Translation plus Transliteration with Positive Connotation naming strategy was the second most appealing approach.

Abstract

Purpose

This paper aims to examine the strength characteristics of a stressful event (i.e. novelty, disruption, and criticality) as factors that drive people’s social media use for seeking different types of supportive resources (i.e. emotional, appraisal, informational, and instrumental support) to facilitate emotion-focused and problem-focused coping. We further assess the impact of different types of social support obtained via social media use on people’s coping effectiveness.

Design/methodology/approach

Our study uses an online survey collecting data at two points in time from 291 social media users during the COVID-19 pandemic. Structural equation modeling was used for data analysis.

Findings

Empirical results reveal the usefulness and limitations of social media use as a coping mechanism. All three event strength characteristics influence people’s social media use for both emotion-focused and problem-focused coping. Event novelty motivates people’s pursuit of informational support on social media, event disruption drives social media use for seeking all four types of support, and event criticality motivates social media use for seeking emotional and informational support. However, only emotion-focused resources – emotional support and appraisal support – are found to significantly affect people’s coping effectiveness.

Originality/value

Our study contributes to a better understanding of the role played by social media when people cope with a stressful event. Applying the three characteristics of event strength allows us to identify people’s need for different supportive resources depending on how they perceive the event. Our analysis of the main and mediating effects of the four types of social support shows that not all types of social support can significantly enhance users’ coping effectiveness.

Abstract

The optimal control of the steady‐state temperature distribution in radiating panels using control heat sources is considered. The problem has important applications in the thermal control of space structures. A mathematical model leads to an elliptic nonlinear optimal control problem. A numerical optimal control method, based on finite element (FE) discretization and sequential quadratic programming (SQP), is employed. Results are presented for some specific examples.

Abstract

Purpose

Social media technology has changed donors' decision-making process in online philanthropy compared with traditional charity. How do IT affordances support donor perceptions and motivations in charitable crowdfunding? The purpose of this study is to explore how the five sub-dimensions of charitable crowdfunding IT affordances (i.e. visibility, association, meta-voicing, trading and security) afford initiators and platforms in motivating donors to support charitable crowdfunding projects.

Design/methodology/approach

This paper uses a quantitative research approach. An online survey was conducted to collect research data from WeChat users who had experienced charitable crowdfunding. A sample of 344 valid responses were received and analyzed.

Findings

The results show that four of the five IT affordances facilitate donors' perceptions (perceived emotions and trust) and motivations (intrinsic motivations and extrinsic motivations), and thereby increase behavioral intention on supporting charitable crowdfunding projects.

Originality/value

This study advances the affordances and online charity literature by examining the antecedents and outcome of perceptions and motivations that determining behavioral intention in more detail. The authors’ findings not only benefit researchers in explaining how technology helps donors perceiving projects and motivating them to donate online, but also assists practitioners in developing better charitable crowdfunding management strategy.

Abstract

Purpose

Through a data-driven theory development approach, this study builds on affordance theory and demonstrates how online mobile app reviews can be analyzed to understand the drivers of informal mobile learning success.

Design/methodology/approach

Textual big data provide a wealth of information regarding user–app relationships and various facets of user engagement. Adopting structural topic modeling and sentiment analysis, the authors extract latent topics from reviews of two educational apps: Duolingo and Photomath.

Findings

The findings suggest that the quality of the relationship between users and mobile learning apps is significantly reliant on how underlying affordances have been actualized. While affordances can leverage satisfaction, they may also be a source of frustration in case of any failure in their design or integration. The analysis reveals eight emergent affordances: practicality, affordability, information reliability, instruction integrity, hedonic experience, user-friendliness, interactive input and iterative upgrading.

Research limitations/implications

Since affordances of a technology entail both enablement and constraint and are best studied as a bundle of connected elements influencing each other reciprocally, the authors discuss how to address potential challenges from technical aspects to the added value of using mobile learning apps.

Originality/value

The results demonstrate that qualitative information in online reviews about mobile learning app experiences is of significant value. The approach demonstrates how advanced analytics can provide business value by addressing the evolving nature of customer needs and expectations. It proves the value of online reviews in discovering underlying technology affordances and their potential boundaries and challenges.
