Abstract

Purpose

China and the USA are among the countries where depression is most prevalent. However, the treatment rate of depression is relatively low in these two countries. Negative attitudes toward depression is one of the major contributor to the low-treatment rate. The purpose of this paper is to examine the use of narratives to promote positive attitudes toward depression in China and the USA. In addition, it examines that the psychological mechanisms underlying narrative persuasion in these two different cultural contexts.

Design/methodology/approach

An online survey was conducted in both China (n=84) and the USA (n=174). Participants were first asked to complete a short questionnaire about their demographic information and depressive symptoms. They were then asked to read a story featuring a college student with depression. After reading the message, participants completed another questionnaire measuring their attitudes toward depression, transportation (i.e. readers’ involvement with the story), and counterarguing (i.e. the generation of thoughts that dispute the persuasive argument).

Findings

Results from a multi-group analysis suggested that although narrative messages had similar persuasive effects for readers from different cultures, the relation between narrative transportation and counterarguing was different. For the US participants, the more they were transported to the story world, the less counter arguments they generated. However, transportation was not negatively associated with counterarguing for Chinese readers.

Practical implications

Findings provide implications for strategically using narrative persuasion to promote positive attitudes toward depression in different cultural contexts.

Originality/value

This study is the first to test the use of narratives to promote positive attitudes toward depression in different cultural contexts.

Abstract

Purpose

Mental illness has become an important public health issue in society, and media are the most common sources of information about mental illnesses. Thus, it is important to review research on mental illnesses and media. The purpose of this paper is to provide a narrative review of studies on mental illnesses in the media and identifies important research gaps.

Design/methodology/approach

A combination of searching key databases and examining reference lists of selected articles was used to identify relevant articles. In total, 41 empirical studies published in the last 12 years were reviewed.

Findings

The review found that substantial research had been done to investigate media portrayals of mental illnesses and the effects of such portrayals might have on the public. Media still portray mental illnesses negatively in general, which contributes to the ongoing mental illness stigmatization. Nonetheless, discussions of mental illnesses in direct-to-consumer advertisements and social media tend to be more objective and informative. These objective portrayals could help improve mental health literacy and reduce stigma. More importantly, media can also reduce the stigma if used strategically. Research has found that entertainment-education programs and web-based media have strong potential in reducing mental illness stigma. Recommendations for future research are also discussed.

Practical implications

Findings can guide future efforts to use media to educate the public about mental illnesses and reduce mental illness stigma.

Originality/value

This study reviews the most recent research on mental illnesses in the media and provides important references on the media representation of mental illnesses, media effects of such representation, and using media to reduce stigma.

Abstract

Purpose

The purpose of this study is to examine the effects of self-affirmation on African American smokers' intentions to quit smoking sooner and desire to stop smoking altogether in response to viewing graphic cigarette warning labels. It also tested the mediating role of perceived susceptibility and self-efficacy in explaining the impact of self-affirmation.

Design/methodology/approach

African American smokers (N = 158) were recruited to participate in a controlled experiment. Participants first completed a short questionnaire about their demographic background and smoking-related attitudes and behavior. They were then randomly assigned to engage in either a self-affirmation task or a control task and viewed two graphic cigarette warning labels subsequently. Participants then responded to a questionnaire about their perceived susceptibility to smoking-related diseases, perceived self-efficacy to quit smoking, intentions to quit smoking and desire to stop smoking altogether.

Findings

Results showed that engaging in self-affirmation prior to exposure to graphic cigarette warning labels increased African American smokers' perceived susceptibility to smoking-related diseases, but decreased their perceived self-efficacy to quit smoking. Furthermore, self-affirmation indirectly enhanced smokers' intentions to quit smoking sooner and desire to stop smoking altogether through increased perceived susceptibility. It also had an unexpected negative indirect effect on intentions to quit smoking sooner through decreased self-efficacy.

Originality/value

This study is one of the few studies that investigates the effect of self-affirmation on African American smokers' responses toward graphic cigarette warning labels.

Abstract

Purpose

Dielectric barrier discharge (DBD) is widely used in the treatment of skin disease, surface modification of material and other fields of electronics. The purpose of this paper is to design a high-performance power supply with a compact structure for excimer lamps in electronics application.

Design/methodology/approach

To design a high-performance power supply with a compact structure remains a challenge for excimer lamps in electronics application, a current-source type power supply in a single stage with power factor correction (PFC) is proposed. It consists of an excitation voltage generation unit and a PFC unit. By planning the modes of the excitation voltage generation unit, a bipolar pulse excitation voltage with a high rising and falling rate is generated. And a high power factor (PF) on the AC side is achieved by the interaction of a non-controlled rectifier and two inductors.

Findings

The experimental results show that not only a high-frequency and high-voltage bipolar pulse excitation voltage with a high average rising and falling rate (7.51GV/s) is generated, but also a high PF (0.992) and a low total harmonic distortion (5.54%) is obtained. Besides, the soft-switching of all power switches is realized. Compared with the sinusoidal excitation power supply and the current-source power supply, the proposed power supply in this paper can take advantage of the potential of excimer lamps.

Originality/value

A new high-performance power supply with a compact structure for DBD type excimer lamps is proposed. The proposed power supply can work stably in a wide range of frequencies, and the smooth regulation of the discharge power of the excimer lamp can be achieved by changing the switching frequency. The ideal excitation can be generated, and the soft switching can be realized. These features make this power supply a key player in the outstanding performance of the DBD excimer lamps application.

Abstract

Purpose

How to use a simple and classical topology to provide a high-efficiency excitation voltage for dielectric barrier discharge (DBD) loads is one of the primary problems to be solved for DBD application fields.

Design/methodology/approach

To address the issue, a set of modes that can generate a high-efficiency pulse excitation voltage in a full-bridge inverter are adopted. With the set of modes, the unique equivalent circuit of DBD loads and the parasitic parameter of the step-up transformer can be fully used. Based on the set of modes, a control strategy for the full-bridge inverter is designed. To test the performance of the power supply, a simulation model is established and an experimental prototype is made with a DBD excimer lamp.

Findings

The simulation and experimental results show that not only a high-efficiency excitation voltage can be generated for the DBD load, but also the soft switching of all power switch is realized. Besides this, with the set of modes and the proposed control strategy, the inverter can operate in a high frequency. Compared with other types of power supplies, the power supply used in the paper can fully take advantage of the potential of the excimer lamp at the same input power.

Originality/value

This work considers that how to use a simple and classical topology to provide a high-efficiency excitation voltage for DBD loads is one of the primary problems to be solved for DBD application fields.
