Previous works on safety behavior have paid less attention to the influence of several leadership styles on safety behavior. Among the various leadership styles, I focus on the effect of coaching leadership on safety behavior. To be specific, this paper investigates the impact of coaching leadership on safety behavior and its underlying mechanisms (mediator) as well as contextual factor (moderator). This research examines the sequential mediating effect of perceived organizational support and organizational identification in the association between coaching leadership and safety behavior. Also, work overload will negatively moderate the coaching leadership-perceived organizational support link. My results showed coaching leadership increases employee safety behavior through the sequential mediation of perceived organizational support and organizational identification. In addition, work overload functions as a negative moderator which diminishes the positive effect of coaching leadership on perceived organizational support.

The purposes of this study were to examine if a decision making by a tourist sequentially or hierarchically occurs in a tourism destination and to test determinants that have an effect on both a sequential and non-sequential decision making. An instrument for the study was developed with three steps. A total of 420 and 380 questionnaire were collected respectively for the first two round surveys. For the third step, a pilot test was conducted with 30 respondents. And the data analysis utilized SPSS 18.0. A logistic regression analysis with variables of tourism activity and demography was employed to investigate the factors that affect a sequence of decision-making process. As an important result, the higher the age of the tourist in a tourism destination, the more conspicuous the consumption expenditure is made through the sequential decision-making process. Additionally, it is unreasonable to apply the premises and assumptions in extant consumer behavior to tourist behavior. The process of decision making by tourists in tourism areas is driven by either non-sequential or non-hierarchical decision-making process. More discussion and implications were provided.

Identification of the nonlinear hysteretic behavior of a reinforced concrete (RC) bridge pier subjected to earthquake loads is carried out based on acceleration measurements of the earthquake motion and bridge responses. The modified Takeda model is used to describe the hysteretic behavior of the RC pier with a small number of parameters, in which the nonlinear behavior is described in logical forms rather than analytical expressions. Hence, the modified extended Kalman filter is employed to construct the state transition matrix using a finite difference scheme. The sequential modified extended Kalman filter algorithm is proposed to identify the unknown parameters and the state vector separately in two steps, so that the size of the problem for each identification procedure may be reduced and possible numerical problems may be avoided. Mode superposition with a modal sorting technique is also proposed to reduce the size of the identification problem for the nonlinear dynamic system with multi-degrees of freedom. Example analysis is carried out for a continuous bridge with a RC pier subjected to earthquake loads in the longitudinal and transverse directions.

Purpose: This study systematically examined the concept of digital selling readiness of salespeople. Additionally, this study empirically confirms the sequential mediating roles of digital literacy and salesperson self-efficacy in the impact of digital selling readiness on customer-oriented behavior. Research design, data, and methodology: We collected data from salespeople at a Bank and Financial Service firm in South Korea. A total of 254 salespeople were invited to participate, with 154 surveys returned. After removing the questionnaires with missing values, 150 complete surveys were employed for the analysis. Results: The empirical analysis indicates that digital selling readiness positively affects digital literacy. Digital literacy, in turn, is positively associated with self-efficacy, leading to increased customer-oriented behaviors among salespersons. This study also confirms the sequential mediating effects of digital literacy and self-efficacy in the impact of salespeople's digital selling readiness on customer-oriented behavior. Conclusions: Our research deepens the understanding of how digital selling readiness fosters customer-oriented behavior through the sequential mediating effects of digital literacy and self-efficacy. This study extends the previous model by sequentially involving digital literacy and self-efficacy to better understand the psychological processes of digital selling. The results highlight the role of digital selling readiness in preparing salespeople for digital sales.

본 연구는 음주 후 나타나는 문제 행동에 초점을 맞추어, 성인 음주자의 기질이 가해행동에 영향을 미치는 과정에서, 공격성과 음주행동의 순차적 매개효과를 분석하였다. 이를 위해 299명에게 기질 및 성격검사(TCI)-성인용, 한국판 공격성 질문지, 한국형 알코올 사용 장애 진단 검사를 실시하였다. 연구결과, 기질 중 자극추구가 공격성에 가장 높은 설명량을 보였다. 자극추구와 가해행동의 관계에서 공격성과 음주행동의 매개효과가 유의하였으며, 그 경로 내에서 공격성과 음주행동의 순차적 매개효과는 완전매개인 것으로 나타났다. 이러한 결과는 공격성과 음주행동이 자극추구와 가해행동을 연결하는 기제로서 자극추구 성향은 가해행동에 직접적인 영향은 없으며 오직 공격성과 음주행동을 통해서만 가해행동에 영향을 미침을 시사한다.

The aim of this study was to explore the mediating effects of adult attachment and marital satisfaction on the relationship between childhood maternal attachment and parenting behavior. A total of 372 mothers of preschoolers completed questionnaires on childhood maternal attachment, adult attachment, marital satisfaction, and parenting behavior. Adult attachment was analyzed by distinguishing between attachment anxiety and attachment avoidance. Parenting behavior was categorized into positive and negative behaviors. For the main analyses, Preacher and Hayes's PROCESS macro program was used to examine serial mediating effects. The results revealed that attachment anxiety mediated the effects of mothers' childhood attachment experiences on both positive and negative parenting behavior. However, attachment avoidance only mediated the effects on positive parenting behavior. Marital satisfaction mediated the effects of mothers' childhood attachment experiences on both positive and negative parenting behavior. Notably, the sequential mediating effects of attachment anxiety and marital satisfaction were not significant for either positive or negative parenting behavior. By contrast, the sequential mediating effects of attachment avoidance and marital satisfaction were significant for both positive and negative parenting behavior. These findings elucidate the predictive factors for parenting behavior within a process model framework, providing valuable insights for parental education and counseling aimed at enhancing mothers' parenting practices.
