Abstract

Purpose

The purpose of this paper is to evaluate the differential effects of help-seeking and product-claim direct-to-consumer advertising (DTCA) on consumers’ attitude toward the ad, intention to seek information and intention to see a doctor. This paper also seeks to examine the underlying mechanism of these effects and the moderating role of advertising literacy.

Design/methodology/approach

An online experiment was conducted with 130 adults who experienced narcolepsy symptoms and experimental stimuli promoting a fictitious drug for narcolepsy.

Findings

Help-seeking DTCA generated lower persuasion knowledge activation than product-claim DTCA, resulting in lower skepticism, more favorable attitude toward the ad and higher behavioral intentions. The effects of ad type were stronger among consumers with higher advertising literacy.

Originality/value

This is the first study that provides a thorough examination of the underlying mechanism of the differential effects of help-seeking vs product-claim DTCA as well as the roles of consumers’ advertising literacy on ad outcomes.

Abstract

Purpose

Currently, countries worldwide are struggling with the virus COVID-19 and the severe outbreak it brings. To better benefit from open government health data in the fight against this pandemic, this study developed a framework for assessing open government health data at the dataset level, providing a tool to evaluate current open government health data's quality and usability COVID-19.

Design/methodology/approach

Based on the review of the existing quality evaluation methods of open government data, the evaluation metrics and their weights were determined by 15 experts in health through the Delphi method and analytic hierarchy process. The authors tested the framework's applicability using open government health data related to COVID-19 in the US, EU and China.

Findings

The results of the test capture the quality difference of the current open government health data. At present, the open government health data in the US, EU and China lacks the necessary metadata. Besides, the number, richness of content and timeliness of open datasets need to be improved.

Originality/value

Unlike the existing open government data quality measurement, this study proposes a more targeted open government data quality evaluation framework that measures open government health data quality on a range of data quality dimensions with a fine-grained measurement approach. This provides a tool for accurate assessment of public health data for correct decision-making and assessment during a pandemic.

Abstract

Purpose

This paper aims to identify consumers' health information consultation patterns by analyzing information sources to better understand consumers' health information needs and behavior in the context of multisource health information.

Design/methodology/approach

Haodaifu Online, an online health consultation (OHC) website in China, was used as a research data source, and 20,000 consultation cases were collected from the website with Python. After screening and cleaning, 1,601 consultation cases were included in this study. A content analysis-based mixed-methods research approach was applied to analyze these cases.

Findings

The results indicate that with the participation of OHC, there are 15 patterns of consumer health information consultation. Besides OHC, health information sources reported by consumers included medical institutions family/friends and the Internet. Consumers consult on a wide range of health issues including surgical conditions obstetrical and gynecological conditions and other 20 subjects. Consumers have multiple information needs when using OHC: getting prescriptions, diagnosing diseases, making appointments, understanding illnesses, confirming diagnoses and reviewing costs. Through further analysis it was found that consumers’ health information consultation patterns were also significantly different in health issues and health information needs.

Originality/value

This study broadens one’s understanding of consumer health information behavior, which contributes to the field of health information behavior, and also provides insight for OHC stakeholders to improve their services.

Abstract

Purpose

The oil film thickness provides a key performance indicator of a ball bearing lubrication condition. This paper aims to propose an approach to calculate and measure the oil film thickness of the bearing.

Design/methodology/approach

On a specially designed test rig, measurement of the capacitance is used to monitor the oil film thickness of ball bearing. A corrected film thickness formula taking account of the influences of non-Newtonian shear thinning and thermal is introduced to predict the oil film thickness of ball bearing. And then the film thickness distribution and the corresponding capacitances are calculated.

Findings

Measurement and calculation of oil film thickness in a ball bearing are carried out under various rotating speeds and external loads. By comparing the calculated capacitances with measured results, it can be concluded that the calculated results obtained by the amended film thickness formula are much closer to the test findings than the classical computed values according to Hamrock–Dowson.

Originality/value

A new corrected film thickness formula is introduced in predicting oil film thickness of ball bearing and verified by the series of experiments according to capacitance method.

Abstract

The density and pattern of urban parks, traffic conditions are the main factors affecting urban park accessibility. To clarify the influence of traffic mode and urban road network on urban park accessibility, we examine downtown area of Nanjing, China, and based on GIS network analysis, analyze urban park accessibility under different traffic modes in the current year (2017) and the Nanjing master planning target year (2030). The results shows: Using automobiles takes the shortest time to get to urban parks in 2017 and 2030 (if the problem of parking is ignored). Comparing the results of 2030 and 2017, by when the ground transportation network in the study area will be further improved, urban park accessibility was improved by a small margin under walking and automobile traffic modes, however, the density of rail traits increased fastest, urban park accessibility is improved most under this mode of transportation, rail transit route development becomes the dominant factor in improving park accessibility in downtown area of Nanjing. To a certain extent, this study reveals the leading factors of improving the accessibility of urban parks on the premise that the system of urban parks tends to be stable, and provides a reference for improving urban park accessibility.

Abstract

Conservation of green space is crucial to the sustainable urban development of China. Nanjing is a central city in the Yangtze River Delta cluster in eastern China. Owing to urbanization, the green spaces in this city have been affected significantly in terms of their scale and structure. Assessing such changes can provide a basis for environmental protection measures and sustainable development. Using Landsat remote-sensing image data from 1998 and 2007, we constructed a distribution map of the patches of green spaces in Nanjing, and analyzed and assessed the changes in scale and spatial layout of the green spaces using various landscape metrics including CA, PLAND, PD, MPS, LPI, NP, PD, TE, ED, MPI, and LSI. Coinciding with a sharp increase in urban population, the area of green spaces in Nanjing decreased by 27.06% between 1998 and 2007. The patches of green space increased by 39%, and the average area per patch decreased by about 47.52%. Green space patches were found to be unevenly distributed among the districts of Nanjing. In urban areas, significant numbers of such patches were found primarily in various types of parks, while in suburban areas, they were concentrated mainly in the hilly forestlands. Green spaces exhibited tendencies towards fragmentation, miniaturization, and discretization.

This paper aims to propose a robust and efficient method for vanishing point detection in unstructured road scenes.

Abstract

Purpose

This paper aims to propose a robust and efficient method for vanishing point detection in unstructured road scenes.

Design/methodology/approach

The proposed method includes two main stages: drivable region estimation and vanishing point detection. In drivable region estimation stage, the road image is segmented into a set of patches; then the drivable region is estimated by the patch-wise manifold ranking. In vanishing point detection stage, the LSD method is used to extract the straight lines; then a series of principles are proposed to remove the noise lines. Finally, the vanishing point is detected by a novel voting strategy.

Findings

The proposed method is validated on various unstructured road images collected from the real world. It is more robust and more efficient than the state-of-the-art method and the other three recent methods. Experimental results demonstrate that the detected vanishing point is practical for vision-sensor-based navigation in complex unstructured road scenes.

Originality/value

This paper proposes a patch-wise manifold ranking method to estimate the drivable region that contains most of the informative clues for vanishing point detection. Based on the removal of the noise lines through a series of principles, a novel voting strategy is proposed to detect the vanishing point.

Abstract

Purpose

The purpose of this paper is to examine the way the message source and presence of positive social cues influence the evaluations (attitude toward the corporate social responsibility (CSR) message and company, and word-of-mouth intention to support the campaign) of the decreased use CSR messages on Facebook.

Design/methodology/approach

In the context of Facebook, this study adopted 2 (message source: a CSR message in a sponsored ad format vs a CSR message posted by another Facebook user) × 2 (social cue: highly salient, positive social cues vs no social cues) factorial experimental design.

Findings

The main effects of message source types and presence of positive social cues on decreased usage CSR campaigns proved to be effective in generating better consumer responses to the company and campaign.

Research limitations/implications

The findings are expected to advance the CSR literature by offering a detailed understanding of CSR campaigns that discourage consumption of the company’s own product to support a social cause. It is suggested to test the effects with other CSR examples to increase the ability to generalize the results further.

Practical implications

The results suggest campaign strategies on social media for public relations practitioners and corporate managers who work for companies conducting social responsibility campaigns that discourage consumption of their own products.

Originality/value

This study contributes to the CSR literature by examining the concept of CSR campaigns that advocate decreased usage, which has received scant scholarly attention to date.

Abstract

Purpose

This paper aims to demonstrate how to make emergency decision when decision makers face a complex and turbulent environment that needs quite different decision-making processes from conventional ones. Traditional decision techniques cannot meet the demands of today’s social stability and security.

Design/methodology/approach

The main work is to develop an instance-driven classifier for the emergency categories based upon three fuzzy measures: features for an instance, solution for the instance and effect evaluation of the outcome. First, the information collected from the past emergency events is encodes into a prototype model. Second, a three-dimensional space that describes the locations and mutual distance relationships of the emergency events in different emergency prototypes is formulated. Third, for any new emergency event to be classified, the nearest emergency prototype is identified in the three-dimensional space and is classified into that category.

Findings

An instance-driven classifier based on prototype theory helps decision makers to describe emergency concept more clearly. The maximizing deviation model is constructed to determine the optimal relative weights of features according to the characteristics of the new instance, such that every customized feature space maximizes the influence of features shared by members of the category. Comparisons and discusses of the proposed method with other existing methods are given.

Practical implications

To reduce the affection to economic development, more and more countries have recognized the importance of emergency response solutions as an indispensable activity. In a new emergency instance, it is very challengeable for a decision maker to form a rational and feasible humanitarian aids scheme under the time pressure. After selecting a most suitable prototype, decision makers can learn most relevant experience and lessons in the emergency profile database and generate plan for the new instance. The proposed approach is to effectively make full use of inhomogeneous information in different types of resources and optimize resource allocation.

Originality/value

The combination of instances can reflect different aspects of a prototype. This feature solves the problem of insufficient learning data, which is a significant characteristic of emergency decision-making. It can be seen as a customized classification mechanism, while the previous classifiers always assume key features of a category.

Abstract

Purpose

This paper examines radical reform of the Chinese public accounting profession in the 1990s. In particular, the paper seeks to provide a more nuanced understanding of the sources, responses and processes of this radical institutional change that effectively paved the way for development of the Chinese accounting profession into the twenty-first century.

Design/methodology/approach

The empirical data that inform this study come from both archival materials (mostly in Chinese) and in-depth interviews. These data are analysed and interpreted from a neo-institutionalist perspective, drawing, in particular, on the concept of institutional logics and the concept of institutional work.

Findings

A state logic initially guided the development of the Chinese accounting profession but was seriously challenged in the 1990s following a series of high profile financial scandals. The findings reveal a shift to a new professional logic, which was made possible through multiple forms of institutional works instigated by various state actors.

Originality/value

Research into the radical reform of the Chinese public accounting profession in the 1990s was mostly quantitative in nature, focussing mainly on one reform programme, i.e. the disaffiliation of the accounting firms from their sponsoring agencies. This paper adopts a qualitative approach and is aimed at providing a deeper and more nuanced understanding of the institutional change process within its political and economic contexts.
