  • Emotional expressiveness is a pathway by which parents affect the emotional competence of their children. This study examined how the emotional expressiveness of parents is influenced by the emotional reactions of their children and demographic characteristics within a family context. Data for the present study were from 200 parents in 100 two-parent families who completed self-report questionnaires for emotional expressiveness, children's emotional reactions to stressful situations, and demographics. In preliminary analyses, mothers expressed emotions more frequently than fathers did, and mothers with high expressiveness of positive emotions were more educated and had higher family income. Although fathers' emotional expressiveness was closely related to mothers' expressiveness, none of the demographic factors were related to fathers' expressiveness. When all predictors were considered in hierarchical multiple regressions, family income was the significant predictor for mothers' positive expressiveness, whereas mothers' negative expressiveness were explained by children's emotional reactions, mother education, child sex, the number of siblings, fathers' education, and mothers' time spent with children. When controlled for mothers' expressiveness, fathers' time spent with children was the only significant predictor for fathers' negative expressiveness. The results of this study suggested that parents' emotional expressiveness varied with socioeconomic status. The discussion also examines the gender differences between mothers and fathers in emotional expressiveness, and their relations to children's sex.

  • Purpose - Pleasing ambient colors, music, scent, layout and salespeople are hypothesized to positively impact shoppers' perceptions about the atmosphere of a store. Few studies on the interactive effect of these atmospheric factors have earlier been undertaken. This paper looks at the interactive effect of color on the other predictor variables. Research design, data, and methodology - This study is from field locations in the shopping malls located in Delhi NCR. A descriptive study was undertaken to decipher the interactive effect of color with music, scent, layout and salespeople. Moderation of color on music, scent, layout and salespeople is regressed on store atmospherics. The authors investigate the effects of color, light, music, scent, layout and salespeople on store atmospherics in a retail context. They also study the interactive effect of color with predictor variables which significantly influence the perception of store atmospherics. Results - The paper reveals that music, scent, layout and salespeople influence customer's perception about store atmospherics. The interactive effect of color with scent, layout and sales people influence customer's perception about store atmospherics significantly. It does not moderate with layout and music. Conclusions - Store color is important in predicting store atmospherics. Care is needed to ensure that the effects of different environmental stimuli match.

  • Reversible image watermarking, a type of digital data hiding, is capable of recovering the original image and extracting the hidden message with precision. A number of reversible algorithms have been proposed to achieve a high embedding capacity and a low distortion. While numerous algorithms for the achievement of a favorable performance regarding a small embedding capacity exist, the main goal of this paper is the achievement of a more favorable performance regarding a larger embedding capacity and a lower distortion. This paper therefore proposes a reversible data hiding algorithm for which a novel piecewise 2D auto-regression (P2AR) predictor that is based on a rhombus-embedding scheme is used. In addition, a minimum description length (MDL) approach is applied to remove the outlier pixels from a training set so that the effect of a multiple linear regression can be maximized. The experiment results demonstrate that the performance of the proposed method is superior to those of previous methods.

  • 문자-음성 합성기 (Text-To-Speech, TTS)에서 해결되어야 할 문제점 중의 하나는 음소의 연결 부위에서 발생하는 불연속성이다. 이러한 문제점을 해결하기 위한 방안으로 본 논문에서는 저역 여파기를 이용한 스무딩 기법을 적용하였다. 제안된 스무딩 기법은 스무딩의 정도를 제어하는 필터 계수를 현재 합성하고자 하는 문맥에 따라 결정하여, 경계에서의 불연속성을 효과적으로 제거하고 스무딩으로 인하여 발생할 수 있는 음성의 왜곡을 억제하였다. 스무딩 정도는 현재 합성된 음성의 불연속 정도와 주어진 문맥으로부터 예측된 불연속 정도를 통해 결정하였으며, 문맥으로부터 불연속 정도의 예측은 음소 정보를 입력, 불연속 값을 출력으로 하는 CART(Classification And Regression Tree)를 통해 이루어진다. 제안된 기법의 성능 평가를 위해 코퍼스 기반 연결(corpus-based concatenative) 문자-음성 합성기를 기본 시스템으로 사용하였으며, 청취 테스트에서 60%이상 의 청취자가 제안된 스무딩 기법을 통해 합성된 음성이 스무딩 기법이 사용되지 않은 경우와 비교하여 명료성과 자연성 면에서 우수하다고 판단하였다.

  • Drawing on the theoretical framework of customer value-satisfaction-loyalty, this study examines how scarcity message influences customers' value, satisfaction, and loyalty in the context of group-buying social commerce. Previous studies have argued that scarcity message limiting the avilability of products and service is a source of enhancing customer value. In this regard, this study posits scarcity message as a predictor of customer value. Furthermore, this study classifies customer value into two forms (i.e., utilitarian value and hedonic value) and verfies how scarcity message is associated with them. To test the proposed research model and hypotheses, this study performed structural equation modeling (SEM) analyses, using a total of 292 data collected on users who have experience in purchasing products and service through group-buying social commerce sites such as Coupang, Timon, and WeMakePrice. The key results are as follows : First, scarcity message increases utilitarian and hedonic values and further customer satisfaction. Second, utilitarian value increases customer satisfaction and repurchase intention while hedonic value has nothing to do with them. The findings imply that customers seek to maximize utilitarian value through group-buying social commerce. Finally, this study indicates that repuchase intention depends greatly on customer satisfaction.

  • This study examines mobile news engagement-conceptualized as news exposure and participation-in the context of South Asia which has experienced tremendous growth in mobile-Internet users without receiving much attention from communication scholars. Along with demographic characteristics, this research incorporates motivational factors (grounded on uses and gratifications-U&G-approach) and news type preferences to explore their roles in mobile news engagement among urban citizens in Bangladesh. Results of a self-administered survey (N = 504) revealed that participants' mobile news engagement partially varied depending on their demographic differences, particularly gender, age, and education. Our study also unveiled that individuals' motivation for sharing information seemed to be a strong predictor of mobile news exposure and participation. In addition, Bangladeshi respondents were more likely to be interested in the hard news in terms of expressing views on news comments and sharing news via mobile platform. Conversely, preference for soft type news had a significant influence on news exposure through mobile browsing. This study provides insights into the understanding of global phenomena of mobile news engagement by unpacking the case of Bangladesh where mobile news usage seems to be an evolving state.

  • Objectives: Adolescents are at risk of suicide. As suicide is a multifactorial process, risk and protective factors are relevant constructs for suicide prediction. This study explored the effects of risk and protective factors on suicidal ideation in adolescents on the island of São Miguel (Azores). Methods: A sample of 750 adolescents (male: n=358; 47.7%; mean age=14.67 years; standard deviation=1.85 years) from the island of São Miguel (Azores) completed several measures related to suicidal ideation and associated factors. Using a cross-sectional design, this study conducted descriptive, correlational, predictive, mediation, and moderation analyses. Results: Adolescents generally displayed high levels of risk and protective factors; an indicative proportion exhibited significant suicidal ideation with females presenting the greatest vulnerability. Furthermore, the results highlight that depression is the best predictor of suicidal ideation, however, the association between these variables is mediated. Conclusion: The data corroborate that the suicidal reality of adolescents in the Autonomous Region of the Azores is worrisome. Having substantiated the complexity of the suicidal context in young people in the present research, the need to continue studying risk/protective factors in this area is supported.

  • Background: This study aimed to examine (1) the patterns of online health information search with respect to seeking and scanning, and (2) how online search, along with eHealth literacy, predicts perceived information usefulness in the context of diet and weight control. Methods: Online survey was conducted with 299 adults from the consumer panel recruited for the purpose of quality assessment of the Korean National Health Information Portal in 2016. We conducted paired sample t-test and multiple logistic regression to address the research questions. Data analysis was performed using IBM SPSS Statistics ver. 24.0 (IBM Corp., Armonk, NY, USA) and SAS ver. 9.3 (SAS Institute Inc., Cary, NC, USA). Results: Of the respondents, 38.8% were 'high seek-high scanners,' 35.8% were 'low seek-low scanners,' 13.0% were 'high seek-low scanners,' and 12.4% were 'low seek-high scanners.' eHealth literacy was a significant, positive predictor of online information scanning (odds ratio [OR], 2.46; 95% confidence interval [CI], 1.41-4.29), but not for online information seeking (OR, 1.75; 95% CI, 1.00-3.05). With respect to perceived usefulness of online information seeking, online seeking (OR, 4.90; 95% CI, 2.19-11.00) and eHealth literacy (OR, 2.30; 95% CI, 1.11-4.75) were significant predictors. Perceived usefulness of online scanning had a significant association with online scanning (OR, 2.38; 95% CI, 1.08-5.22), but not with eHealth literacy. Conclusion: To increase the effectiveness of the health policy for online information search and related outcomes in the context of diet and weight control, it is important to develop education programs promoting eHealth literacy.

  • Teachers can maximize students' L2 learning by knowing preferred learning styles. This paper presents the results of a survey that asked 309 English learners to identify their perceptual learning style preferences. It further compared students' favored learning styles in terms of their gender and major field of study and explored a possible link between learning styles and English achievement. Collected data using Reid's (1995) questionnaire were analyzed by descriptive statistics, MANOVA, ANOVA, correlations, multiple regressions including squared partial correlations, and Cronbach's alpha. The results indicated that Korean students favored English learning in group regardless of gender, while their preferred mode of learning was significantly different in regard to their major field of study. Certain learning styles might be profitable for English achievement. Multiple regression analyses revealed that individual mode of learning was the best predictor of students' English achievement. It furthermore showed significant relationships between visual and individual styles of learning and English performance. The findings of the study reflected students' English learning context in which English native-speaking teachers frequently used communicative pair and small group activities for speaking practices that were consonant with students' learning styles.

  • This study determines what affects the academic achievement of senior high school students in the context of the individual, family, and school environment. The sample selection consisted of 1484 high school seniors in Korea. The following are the results of this study: First, female students scored higher in academic achievement than male students. Second, academic achievement by male students was related to levels of school satisfaction, academic motivation, and family strength, while academic achievement by female students was related to levels of parents' education, family income, ego-resiliency, school satisfaction, academic motivation, and family strength. Third, the most important predictor of academic achievement for male and female students is academic motivation, followed by school satisfaction. The present study highlighted the necessity to develop academic achievement improvement programs appropriate for both genders of senior high school students.
