Although former scholarly studies mostly focus on exploring leadership effectiveness under the traditional hierarchical leader-subordinate relationship, the research of leadership performance for non-hierarchical organizational structures, particularly the mediating factors of higher-order goals, trust-in-leader, and self-efficacy have been ignored. This study, therefore, makes an attempt to ascertain the impacts of transformational leadership on the performance of subordinates through the mediating effects of higher-order goals, trust-in-leader, and self-efficacy and the differences of these effects in the context of multi-level marketing (MLM). Like the small-sample studies adopted by Barling, Weber, and Kelloway [1996], Barling, Slater, and Kelloway [2000] and Bass, Avolio, Jung, and Berson [2003], this study adopts a sample of 123 MLM distributors of an MLM company in Hong Kong, with a high response rate of 80.4%. The results indicate that the mediating effect of self-efficacy between transformational leadership and performance is significant under non-hierarchical organizational structures such as MLM in China.

The aim of this study was to explore the types of helicopter parenting among college students, and to examine how the identified types of helicopter parenting are associated with intimacy goals in dating. In order to investigate these purposes, 202 college students were recruited and analyzed. With the use of Mplus 7.4, a latent profile analysis identified latent profiles of helicopter parenting. Additionally, multivariate regression analysis was conducted in order to analyze the links between the types of helicopter parenting and intimacy goals in dating by using SPSS 26.0. The main findings of the study were as follows. Firstly, three helicopter parenting classes were identified: 1) strong decision-making, 2) strong helicopter parenting, 3) weak helicopter parenting. Secondly, college students in the strong helicopter parenting class reported significantly higher levels of intimacy goals in dating than those in the strong decision-making class. On the other hand, no significant connection was identified between the type of 'weak helicopter parenting' and the levels of intimacy goals in dating, referencing the type of 'strong helicopter parenting.' These results indicate that helicopter parenting has a certain number of types in nature, and the control-based parental behavior could have an impact on college students' intimacy goals in dating.

This research exercise was undertaken in order to examine whether academic achievement, academic attitudes, achievement goals, and family process had an influence on beliefs about intellectual ability. The subjects were 434 junior-high school students in Seoul and Incheon. The results of this study indicated that 162 students with incremental beliefs had higher scores in all five sub-factors of academic attitudes, two sub-factors in their achievement goals (namely their mastery goals and approach performance goals), and four sub-factors of family process (closeness, monitoring, communication, and approval) than 155 students with entity beliefs. The results of the binary logistic regression analysis revealed that academic self-perceptions, attitudes towards teachers, goal values, approach performance goals, closeness, and communication factors significantly affected beliefs about intellectual ability.

The purpose of this study was to investigate the effects of online ballet community-based teacher-parent computer-mediated communication (CMC) on four achievement goals of ballet students. We used a randomized post-test only control group design. In order to test whether teacher-parent CMC has a positive impact on the improvement of achievement goals, multivariate analysis of covariance were performed with the ages of ballet students as the covariates. Teacher-parent CMC had significant effects on achievement goals. The mastery-approach goals of the experimental group were significantly higher than of the control group. In contrast, the performance-avoidance goals of the experimental group were significantly lower than those of the control group. There were no differences between the two groups in mastery-avoidance and performance-approach goals. Above all, this study is significant because the focus was placed on the inter-relationship between the two settings of school and family in regard to ballet student improvement, rather than on one setting only.

MODM (multiobjective decision-making) problem is very complex system for the analyst. The problem is more complex if the goals of each of the objective functions are expressed imprecisely. It requires suitable MODM method to deal with imprecisions. Therefore, we present a new interactive fuzzy decision making method for solving multiobjective nonlinear programming problems by assuming that the decision maker (DM) has imprecise goals that assume fuzzy linguistic variable for each of the objective functions. The imprecise goals of the DM are quantified by eliciting corresponding membership functions through the interactive with the DM out of six membership functions. After determining membership functions, in order to generate the compromise or satisficing solution which is .lambda.-pareto optimal, .lambda.-max problem is solved. The higher degree of membership is chosen to satisfy imprecise goals of all objective functions by combining the membership functions. Then, the values are the compromise or satisficing solution. On the basis of the proposed method, and interactive computer programming is written to implement man-machine interactive procedures. Our programming is a revised version of sequential unconstrained minimization technique. Finally, a numerical example illustrates various aspects of the results developed in this paper.

교양교육으로서의 소프트웨어(SW) 교육의 중요성과 필요성은 사회적 공감이 이루어졌다. 하지만, SW 교양교육 학습자의 학습 동기는 다양한 이유로 인해 낮게 유지되는 것으로 알려져 있다. 따라서 SW 교양교육에서 학습동기 및 이의 변화에 관한 이해가 필요하지만, 관련 연구가 부족한 것이 현실이다. 본 논문에서는 SW 교육 학습자들의 한 학기 동안의 학습동기 변화를 살펴보기 위해 3 × 2 성취목표 모델을 이용해 성취목표 변화를 분석하였다. 분석 결과, 학생들의 성취목표는 집단수준과 개인 수준 모두에서 안정적이었으나, 각 하위 성취목표의 순서는 기존 연구와 차이를 보였다. 또한, 교실목표구조의 숙달목표는 기존 연구보다 높은 강한 상관관계를 보였으나, 수행목표는 일부 회피 목표와만 상관관계가 있는 것으로 확인되었다. 이는 SW교양교과에서의 학습동기는 기존 교양교과와 다른 특징을 가지고 있으므로 SW교과에서 사용하는 교실목표구조 유형에 따른 추가 연구가 필요함을 의미한다.

This study investigates how well pre-teachers in preschools aware the importance of science teaching methods, goals and efficacy, and how different the pre-teachers recognize the importance of methods and goals in science teaching according to the levels of their science teaching efficacy. The subjects were 207 pre-service preschool teachers in Chonnam University and Chonbuk University. The data were collected by using three questionnaires("Science teaching efficacy", "Science teaching goal" and "Science teaching method"). The data were analyzed by a t-test and descriptive statistic. The results are as follows: first, the efficacy levels of the pre-teachers are higher than the average. The pre-teachers perceive a 'process-oriented' goal more importantly than a 'content-oriented' goal in early science education. Also, they recognize science teaching methods as being significant in the order of an 'interactive' approach, an 'activity-discovery' approach and a 'knowledge-transmission' approach. Second, the pre-teachers with high teaching efficacy recognize a 'process-oriented' goal as being more important than those with low teaching efficacy do.

Due to the fashion industry taking responsibility for their garment manufacturing, a significant number of UK universities are focusing on combining sustainability in their curriculum to support future employees' skills and knowledge in sustainable fashion. A proper understanding of educational and instructional theories is needed to develop effective teaching and learning materials and environments. Therefore, this study aimed to evaluate the Fashion Design module created with consideration of sustainability using ADDIE instructional model. For evaluation, the teaching materials, including the module brief and the PowerPoint slides for each session, were used. Ten students were interviewed and observed along with two tutors, also interviewed to analyze the strengths and weaknesses of the module from a variety of viewpoints. With sustainable fashion being embedded into specialized higher education courses, tutors decided to incorporate sustainability into the module as an introduction to this topical subject in order to build a stronger foundation of knowledge and challenge traditional ways of working. Results showed that combining sustainability into the design and technical sessions had a positive influence on students who built upon their existing knowledge. Tutors researched the need for change within the industry in line with the Sustainable Development Goals and aligned the content to inform the students of the current crisis. This study could provide a guideline to create instructional material for sustainable fashion design courses.
