Abstract

Purpose

Design, fabricate and evaluate all-solid-state wearable sensor systems that can monitor ion concentrations in human sweat to provide real time health analysis and disease diagnosis capabilities.

Design/methodology/approach

A human health monitoring system includes disposable customized flexible electrode array and a compact signal transmission-processing electronic unit.

Findings

Patterned rGO (reduced-graphene oxide) layers can replace traditional metal electrodes for the fabrication of free-standing all solid film sensors to provide improved flexibility, sensitivity, selectivity, and stability in ion concentration monitoring. Electrochemical measurements show the open circuit potential of current selective electrodes exhibit near Nernst responses versus Na+ and K+ ion concentration in sweat. These signals show great stability during a typical measurement period of 3 weeks. Sensor performances evaluated through real time measurements on human subjects show strong correlations between subject activity and sweating levels, confirming high degree of robustness, sensitivity, reliability and practicality of current sensor systems.

Originality/value

In improving flexibility, stability and interfacial coherency of chemical sensor arrays, rGO films have been the developed as a high-performance alternative to conventional electrode with significant cost and processing complexity reduction. rGO supported solid state electrode arrays have been found to have linear potential response versus ion concentration, suitable for electrochemical sensing applications. Current sweat sensor system has a high degree of integration, including electrode arrays, signal processing circuits, and data visualization interfaces.

Abstract

Purpose

This paper aims to establish a photoacoustic detection system for SO2 using UV-LED and testify its feasibility for sensitive measurement. The work in this paper can avoid potential crossover interference in infrared (IR) range and also balance the capability and cost of feasible excitation for photoacoustic detection system.

Design/methodology/approach

In this experimental work, a cantilever-enhanced–based photoacoustic SO2 detection system using an ultraviolet (UV) LED light source with a light power of 4 mW as the excitation was established.

Findings

A feasible photoacoustic detection system for SO2 using UV-LED was established. Experimental results demonstrate that the detection limit of the system can reach the level of 0.667 ppm, which can serve as a reference for the application of PAS in insulation fault diagnosis.

Originality/value

This work investigated the potential of using ultraviolet photoacoustic spectroscopy to detect trace SO2, which provided an ideal replacement of infrared-laser-based detection system. In this paper, a photoacoustic detection system using LED with a low light power was established. Low light power requirement can expand the options of light sources accordingly. In this paper, the absorption characteristics of SO2 in the presented detection system and ultraviolet range were studied. And the detection limit of the presented system was given. Both of which can provide reference to SO2 detection in ambient SF6.

Abstract

This article presents an application of survey non-response theory to a specific population with disabilities. From 1994 to 1997 the U.S. National Health Interview Survey (NHIS) did a special, two-phase study of disability. This survey format allowed for response patterns of the disabled population to be operationalized into contact, cooperation and proxy/assisted versus self-response categories. Using these data, the authors investigated the effects of severity of activity limitation at first interview on response patterns at second interview, with statistical controls for other characteristics related to the response outcome. The statistical results of the study show that respondents with moderate or severe activity limitation are more likely than those with mild activity limitation to be contacted and to cooperate, yielding higher response rates. However, respondents with a higher degree of activity limitation are also more likely to have proxy/assisted responses at re-interview. Barriers to self-response in household surveys are discussed in the concluding remarks.

Abstract

Purpose

The purpose of the study was to examine the effect of corporate social responsibility (CSR) and marketing capability on consumer behavioral responses in the mobile telecommunication industry in Ghana. Particularly, the study estimated the moderating effect of marketing capability on the relationship between CSR and consumer behavioral responses.

Design/methodology/approach

Both customers and employees of three major mobile telecommunication companies were sampled for this work. A mixed linear regression technique was used to examine the relationship between corporate responsibility, marketing capability and customer behavioral responses.

Findings

The empirical results revealed that marketing capabilities moderate the relationship between CSR and consumer responses in the telecommunication industry.

Research limitations/implications

The study proposes practical dimensions to the mobile telecommunication companies that the extensive development of strong marketing capabilities serves a conduit for CSR to achieve favorable consumer responses.

Originality/value

The results have opened up rather a limitation studies on the moderation role marketing capabilities in relationship between CSR and consumer behavioral responses in the telecommunication industry.

The purpose of this study is to explore how business-only corporate responsibility coalitions (CRCs) help member firms manage sustainability issues.

Abstract

Purpose

The purpose of this study is to explore how business-only corporate responsibility coalitions (CRCs) help member firms manage sustainability issues.

Design/methodology/approach

This conceptual analysis of business-only CRCs, using the literature on sensemaking and social issues management, explores how participation in CRCs enhances firms’ capabilities for sustainability issues management by improving their sensemaking competencies, abilities to choose and adapt issue responses and efficiency in implementing issue responses through better issue response mechanisms.

Findings

Business-only CRCs help firms with high as well as low levels of sustainability orientation better manage sustainability issues by carrying out the exploratory aspects of issues management: scanning, identifying and evaluating issues and proposing responses to issues.

Practical implications

The widely applicable, nonbinding and scripted responses proposed by CRCs allow participating firms a high degree of autonomy to choose and adapt their responses. However, firms must approach their CRC memberships with collaborative intent and high transparency to achieve these benefits.

Social implications

Participation in CRCs can help scale up firms’ responses to sustainability issues through more efficient issues management processes that allow them to customize issue responses to their needs.

Originality/value

Research on the management of sociopolitical issues can be enriched if these issues are understood as collective, multilevel challenges rather than purely strategic issues faced by individual firms. This study contributes to the business collective action and issues management literatures by emphasizing the importance of collective management of sustainability issues and how it may improve firms’ capabilities for sustainability issues management.

Abstract

Purpose

The current study examines (1) the relationships among the crisis response, trust and negative behavioral intentions (i.e. avoidance and revenge), (2) the mediation role of trust in the crisis communication of sports organization and (3) the moderation effect of team identification between the crisis response and trust.

Design/methodology/approach

A questionnaire was used to collect data from 324 Major League Baseball (MLB) fans who met specific criteria (i.e. background information; knowing about the Houston Astros sign-stealing scandal and how the team responded to it). Confirmatory factor analysis and structural equation modeling were employed to test the proposed hypotheses.

Findings

The findings showed that perceived adequacy of the crisis response positively influenced sports fans' perceived trust. This trust was negatively associated with revenge and avoidance intentions. The mediation effect of trust was also found in the relationship between the crisis response and both avoidance and revenge intentions. Regarding the interaction effect of team identification, however, the relationship between the crisis response and trust was not moderated by team identification levels.

Originality/value

The present study contributes to a comprehensive understanding of crisis communication in sports fans' perceptions and behavioral intentions. It illuminates a psychological process through which perceived adequacy of crisis response reduces negative behavioral intentions through trust.

Abstract

Purpose

Following the traditions of stakeholder salience theory, this paper aims to contend that some institutional investor activists and tactics have more power, legitimacy and urgency than others.

Design/methodology/approach

The author undertakes an empirical test of a saliency table looking at the effects of institutional investor heterogeneity on portfolio firm responses using ordinal logistic regression.

Findings

This study found heterogeneity for institutional investor type to drive firm responses but not tactic type raising the importance of the attributes of each type of investor activist. The author found a rank ordering of public pension plans, hedge funds and then private multiemployer funds in saliency to portfolio firms. In addition, the use of proxy-based tactics did not help or hurt each investor type. Both findings challenge prior empirical work.

Originality/value

The rank ordering based upon the heterogeneity of institutional investor activists and their tactical interactions are tested providing empirical evidence of the most influential activist investors and tactics in one study, which is rare in the literature.

Abstract

Purpose

The aim of this study is to develop and redesign the Mobile Panic Button UI (PB1) application as an emergency notification service, as well as conduct a simulation on the use of the new version of the application.

Design/methodology/approach

This study used the operational research design with a theoretical research framework that followed input, process and output. Primary data were collected through observation, measurement and interview while the secondary data were obtained from literature review. The first step of the analysis was input analysis that included problem identification on the existing Panic Button as input, or PB 1 in this study. This was followed by the analysis of the planned second version of the Panic Button (PB2) development, starting from problem identification to trial and error testing and evaluation of the results of the simulation of seven types of emergency events that involved users, emergency response officers and experts.

Findings

The study shows that the first version of PB1, developed in and used since 2017 at Universitas Indonesia, still had several weaknesses, particularly in its inability to provide adequate information. Only 30% of the standards for a mobile emergency application were met by PB1, which affected the performance of emergency responses. This was one of the reasons why the new version of Panic Button UI (PB2) was developed. The new features in PB2 comprise the inclusion of features for collecting information on user's name and mobile phone number, emergency category options, victim information, photo/voice information, description on the nature of the emergency (text), location selection, emergency notification delivery, notification delivery popup and emergency notification delivery to the emergency response team (ERT) officer. The time needed for using the second version of the Panic Button UI mobile application is 20 s faster than the previous one. PB2 can accelerate response time and response action time; improve response accuracy; facilitate the emergency notification process; and facilitate emergency communication.

Originality/value

Various notification alert systems have been developed in many countries. However, there is a lack of information in Indonesia, especially in educational setting. This study is the first study on a notification alert system application applied in the university. Emergency response is critical due to the big impact of disasters. This study will inform the stakeholders or users, particularly those in educational institution on how to implement mobile app–based emergency response notification systems.

Abstract

Purpose

Food packaging pictures are one of the most important extrinsic cues for consumers to evaluate food products before purchasing. Over the past decades, marketers have used exaggerated pictures to attract consumers' attention, enhance their attitude toward a product and increase their purchase intention. This study examined the interplay of “puff-up” product picture, food type and picture type in influencing consumers' responses via persuasion knowledge.

Design/methodology/approach

The research comprises two 2 × 2 factorial experiments. Study 1 tested the interaction effect of puffery (high vs low) and food type (utilitarian vs. hedonic) on consumers' responses using two fictitious brands of prepared food, whereas Study 2 tested the interaction effect of puffery (high vs. low) and picture type (ingredients vs. cooked food) using a fictitious brand of Chinese delicacy.

Findings

Results demonstrated that the degree of picture puffery did not influence consumers' responses to utilitarian food and ingredient image. Conversely, consumers were sensitive to puffery when they see hedonic food and cooked-food image. Our findings also suggested that consumers' persuasion knowledge mediates the relationship between puffery and their responses.

Practical implications

The presented findings facilitate marketers to know consumers' attitude about food puffery pictures.

Originality/value

This research is one of the first efforts to empirically explore the influences of persuasion knowledge on food puffery pictures. The importance of this work is underscored by the fact that a growing number of visual exaggerations are adopted on food packaging.

Abstract

Purpose

Decision-makers in companies increasingly face unprecedented natural disasters. When business continuity is at risk, managers need a framework to imminently react.

Design/methodology/approach

A literature review and analysis of survival responses in nature and business case examples of company responses to the Covid-19 pandemic was the approach used.

Findings

There are direct parallels between the physiological stress response when a living individual perceives a threat to its survival, and the immediate reactions that occur when companies are faced with a disruptive event.

Practical implications

This article is meant to be used by decision-makers in companies to better react to disruptive events.

Originality/value

While nature-inspired methods have inspired inventions and algorithms, Hans Selye's general adaptation theory has not been used in parallel with business scenarios. We correlate fundamental organism survival mechanisms with a risk response framework to improve the probability of business survival during external threats.
