Abstract

We model the conditions under which parents optimally reallocate time to childcare when an outside agent exogenously restricts the number of hours an employer can demand of a working parent. Theoretically, when the restriction binds, a parent's available time increases. We exploit a series of voluntary and mandated labor-market reforms in South Korea that regulated the statutory and maximum work hours of parents. The government implemented the laws in stages by industry and size of firms. This implementation process generates exogenous variation across families where one or both partners worked at jobs that were or were not affected by the reform. We show the reforms affected work hours and use the predicted changes to investigate the total amount they spent on paid childcare and whether or not they changed the relative use of market and parental care. When fathers get more time (work less), parents spend less money on childcare. A change in mother's work time does not affect expenditures. When parents get more time, they are more likely to spend money on paid childcare for school-age children and more likely to use private academies.

Abstract

Purpose

The purpose of this paper is to compare and validate the results of two clustering methods for the segmentation of the market for prestige cosmetics in Korea, and to draw conclusions about their general practical usability.

Design/methodology/approach

Segmentation schemes based on scaled data collected by questionnaire from 480 female shoppers, selected by the mall intercept procedure, were analysed for validity, model fit, definability of profiles, and usability of results.

Findings

Segmentation by traditional K‐means clustering was not judged useful, whereas segments generated by the innovative alternative of mixture regression modelling had clear marketing strategy potential.

Research limitations/implications

Given the single‐country and single‐market context of the study, its outcomes and implications must be generalised cautiously.

Practical implications

Mixture regression can make a significant contribution to the implementation of segmentation strategies based on deliverable consumer benefits, by helping academics and practitioners to better understand, explain and predict patterns of consumer behaviour.

Originality/value

A segmentation model with proven validity offers a sound basis for such marketing strategies as, for example, positioning.

Abstract

Purpose

The purpose of this paper is to investigate how we can understand social media interactions better by explicating the process of social capital formation on Facebook from a reciprocity perspective.

Design/methodology/approach

This study observed users who got tagged on Facebook by his/her friends and how s/he responded to that tagging activity. In total, 4,666 posts and 418,580 comments from The New York Times Facebook page were collected for the observation.

Findings

A majority (77.87 percent) of users who were tagged by their friends showed reactions to their tagging. In detail, 33.63, 44.20, and 0.04 percent of users responded by comments, “Likes”, and “Shares”, respectively. In total, 90.11 percent of the comments and 98.58 percent of the “Likes” were expressed on a comment or sub-comment, and only 9.89 percent of the comments and 1.42 percent of the “Likes” were expressed on a post. This indicates that a high percentage of users respond to their tagging notification, and they prefer dialogic responses to non-dialogic responses.

Originality/value

Previous studies have focused on photo tagging activity in social media, but user tagging activity had not been studied enough. This study examines the effects of Facebook tagging activity from a reciprocal perspective.

Abstract

Purpose

The purpose of this study is to investigate whether the framework of brand credibility effects is applicable to service categories and to examine if brand credibility's impact differs according to service type and involvement level.

Design/methodology/approach

Using a self‐administered survey (n=385), this study tests the proposed model, including six latent constructs: brand credibility, perceived quality, perceived risk, information costs saved, perceived value for money, and purchase intention.

Findings

The results indicate that brand credibility exerts a strong effect on purchase intention by increasing perceived quality, perceived value for money, and information costs saved, and by decreasing perceived risk across multiple service categories. The results also indicate that the magnitude of brand credibility's impact on purchase intention varies under different conditions with regard to utilitarian and hedonic services.

Research limitations/implications

This study is based on student samples with a limited number of service categories. Future research is needed to examine the generalizability of the proposed model by using non‐student samples with different service classifications.

Practical implications

Establishing brand credibility seems to be especially effective in utilitarian services when marketing communication campaigns have the consistency of brand attributes that invoke either value for money or lower service brand‐related information efforts.

Originality/value

This study offers an initial attempt to explain how brand credibility influences its key outcomes under different service classes. Perceived value for money could be considered a new mediator of a causal relationship between brand credibility and purchase intention in service sectors.

Abstract

Purpose

This paper aims to give an overview about the state of wireless passive surface acoustic wave (SAW) gas sensor used in the detection of chemical vapor. It also discusses a variety of different architectures including delay line and array sensor for gas detection, and it is considered that this technology has a good application prospect.

Design/methodology/approach

The authors state the most of the wireless passive SAW methods used in gas sensing, such as CO2, CO, CH4, C2H4, NH3, NO2, et al., the sensor principles, design procedures and technological issues are discussed in detail; their advantages and disadvantages are also summarized. In conclusion, it gives a prospect of wireless passive SAW sensor applications and proposes the future research field might lie in the studying of many kinds of harmful gases.

Findings

In this paper, the authors will try to cover most of the important methods used in gas sensing and their recent developments. Although wireless passive SAW sensors have been used successfully in harsh environments for the monitoring of temperature or pressure, the using in chemical gases are seldom reported. This review paper gives a survey of the present state of wireless passive SAW sensor in gas detection and suggests new and exciting perspectives of wireless passive SAW gas sensor technology.

Research limitations/implications

The authors will review most of the methods used in wireless passive SAW sensor and discuss the current research status and development trend; the potential application in future is also forecasted.

Originality/value
