Microfoundations of institutions are central to constructing place – the interplay of location, meaning, and material form. Since only a few institutional studies bring materiality to the fore to examine the processes of place-making, how material forms interact with people to institutionalize or de-institutionalize the meaning of place remains a black box. Through an inductive and historical study of Boston’s North End neighborhood, the authors show how material practices shaped place-making and institutionalized, or de-institutionalized, the meaning of the North End. When material practices symbolically encoded meanings of diverse audiences into the church, it created resonance and enabled the building’s meanings to withstand environmental change and become institutionalized as part of the North End’s meaning as a place. In contrast, when the material practices restricted meaning to a specific audience, it limited resonance when the environment changed, was more likely to be demolished and, thus, erased rather than institutionalized into the meaning of the North End as a place.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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

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.

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

The purpose of this paper is to examine the factors that drive students to use Facebook for educational communication and explore the impact of Facebook use for educational communication on perceived academic achievement.

A survey was conducted through a self-administered questionnaire to collect data from student Facebook users at a large technology and engineering university in Malaysia. Partial least squares path modeling was used to test the hypotheses in the research model.

This empirical study showed that Facebook use in educational communication is determined by subjective norms and purposive value. Facebook use in educational communication positively affected perceived academic achievement.

The findings provide useful insight for higher institutions and educators regarding the potential academic effects of integrating Facebook into higher education learning. Moreover, this study provides insight into the factors that drive Facebook use in educational communication.

Prior studies have largely investigated the determinants and the effects of Facebook use among university students. However, little research has focused on educational communication phenomena. This study investigated determinants and academic achievement effect of Facebook use in educational communication among university students.
