汉语作为第二语言的越南大学生汉字部件意识的发展*

以226名将汉语作为第二语言的越南大学一到四年级学生为研究对象,以低频独体字、部件熟悉假字和部件不熟悉假字为材料,采用延迟书写任务,考察了不同年级的越南大学生汉字部件意识的发展及其影响因素。结果发现：（1）学习3个月汉语的大一学生能以部件作为汉字加工单元,其延迟书写部件熟悉假字显著好于低频独体字,并与高年级学生没有差异,说明越南大学生很早就发展出了汉字部件意识;（2）不同年级大学生书写部件不熟悉假字的成绩都显著低于部件熟悉假字,也低于低频独体字,表明部件构字能力是越南大学生汉字书写的重要影响因素。（3）越南大一学生的汉字书写成绩受到汉字结构的影响,左右结构优于上下结构,但其他年级的成绩不受汉字结构的影响。     

Consumer ethnocentrism,cultural sensitivity,and intention to purchase local products—evidence from Vietnam

• This study empirically investigates the impacts of consumer ethnocentrism and cultural sensitivity on both imported product judgment and intention to purchase local products in the context of a developing country—Vietnam. Structural equation modeling was used to test these impacts, utilizing a sample of 549 consumers. The results show that consumer ethnocentrism is negatively related to imported product judgment and positively related to intention to purchase local products. In addition, cultural sensitivity has a positive relationship with imported product judgment but not with consumer ethnocentrism. The results also indicate that the impacts of consumer ethnocentrism on imported product judgment and on intention to purchase local products are not different in terms of product categories, gender, income, and education levels. However, differences exist between younger and older consumers.

Constructing Finite Least Kripke Models for Positive Logic Programs in Serial Regular Grammar Logics

A serial context-free grammar logic is a normal multimodal logicL characterized by the seriality axioms and a set of inclusionaxioms of the form _ts1..._sk. Such an inclusion axiom correspondsto the grammar rule t s₁... s_k. Thus the inclusion axioms ofL capture a context-free grammar . If for every modal index t, the set of words derivable fromt using is a regular language, then L is a serial regular grammar logic. In this paper, we present an algorithm that, given a positivemultimodal logic program P and a set of finite automata specifyinga serial regular grammar logic L, constructs a finite leastL-model of P. (A model M is less than or equal to model M' iffor every positive formula , if M then M' .) A least L-modelM of P has the property that for every positive formula , P iff M . The algorithm runs in exponential time and returnsa model with size 2^O(n³). We give examples of P and L, for bothof the case when L is fixed or P is fixed, such that every finiteleast L-model of P must have size 2⁽ⁿ⁾. We also prove that ifG is a context-free grammar and L is the serial grammar logiccorresponding to G then there exists a finite least L-modelof _s p iff the set of words derivable from s using G is a regularlanguage.     

Imitation of a two-action sequence by pigeons

Developmental psychologists have describedimitation as a process that suggests perspective-taking abilities. However, imitative behavior has been found in animals, which are generally not considered capable of taking the perspective of another. Previous studies with birds have demonstrated the imitation of a single response (sometimes referred to asaction-level imitation). In the present experiment, we examined the extent to which pigeons would imitate an unfamiliar sequence of two behaviors (sometimes referred to asprogram-level imitation). Our results indicate that, although there are individual differences, pigeons show a significant tendency to match a demonstrated sequence of behavior involving, first, a response to a treadle (pecking at it or stepping on it) and, second, pushing aside a screen that blocks access to food (a left-vs.-right push).     

Developing trends in showrooming,webrooming, and omnichannel shopping behaviors: Performance analysis,conceptual mapping,and future directions

In an omnichannel era, businesses and marketers need insights into the dynamics of customer shopping behaviors, particularly the interplay between omnichannel, showrooming, and webrooming behaviors. This study investigates the evolution and trends of the research and channel shopping behaviors (RCSB) domain, spanning from 1998 to 2022, including the Covid-19 era. The study performed a bibliometric review of 500 papers in the Scopus database. The performance analysis reveals an annual growth rate of nearly 16%, with average citations per document of 44, indicating sustained and growing research interest. Science mapping revealed five distinct cluster themes, including showrooming and webrooming in multi- and omni-channel contexts; consumer behavior in online retail and shopping; customer satisfaction and trust in multi-channel retailing; mobile commerce in a multi-channel environment; and the interplay between online shopping, channel choice, and supply chain management. Furthermore, topics, such as showrooming, e-commerce, retailing, and omnichannel retailing, remain popular before and during the pandemic, as seen in the thematic evolution. Our examination of the thematic maps revealed various topics that gained significance during the pandemic, such as multichannel, channel choice, customer experience, social commerce, purchase behavior, and covid-19. Among these, the thematic maps indicate that customer experience, channel choice, multichannel, and covid-19 are emerging and basic topics. These topics can steer research directions in the RCSB domain toward examining customer experiences using digital innovations, e-commerce (including mobile and social commerce), and omnichannel strategy and management.     

Individual differences in the preference for worked examples: Lessons from an application of dispositional learning analytics

Worked-examples have been established as an effective instructional format in problem-solving practices. However, less is known about variations in the use of worked examples across individuals at different stages in their learning process in student-centred learning contexts. This study investigates different profiles of students' learning behaviours based on clustering learning dispositions, prior knowledge, and the choice of feedback strategies in a naturalistic setting. The study was conducted on 1,072 students over an 8-week long introductory mathematics course in a blended instructional format. While practising exercises in a digital learning environment, students can opt for tutored problem solving, untutored problem solving, or call worked examples. The results indicated six distinct profiles of learners regarding their feedback preferences in different learning phases. Finally, we investigated antecedents and consequences of these profiles and investigated the adequacy of used feedback strategies concerning ‘help-abuse’. This research indicates that the use of instructional scaffolds as worked-examples or hints and the efficiency of that use differs from student to student, making the attempt to find patterns at an overall level a hazardous endeavour.     

The Question of Survival: The Death of Desire and the Weight of Life

This article aims to document the psychic injuries of torture. Psychic deadness, erasure of intersubjectivity, refusal of meaning-making, perversion of agency, and an inability to bear desire constitute the core features of the post-traumatic landscape of torture. The existential challenges in traumatized lives is examined, and questions are also raised about the ethics and unconscious defensive functions of the term "survival." Clinical materials with various torture patients are reported to explore the process of working through the losses and paradoxes of trauma. The role of unmourned loss and the defense of fetishizing the trauma are highlighted as the motivating force and the problem in the current preoccupation with trauma in modern Western culture.     

Psychological Hardiness in Learning and Quality of College Life of Business Students: Evidence from Vietnam

Vietnam’s continuing economic transformation has sharply increased the demand for highly-qualified business graduates. Vietnamese universities have responded to this increase in demand by improving the quality of their programs and raising their performance standards. The degree to which high-quality competitive programs increase students’ satisfaction with their educational experience is determined by their psychological hardiness in learning, their learning motivation, and their assessments of the functional value of business education. This study gathered survey data from a convenience sample of 1,024 business students in Vietnam, then validated measures of four constructs: Quality of College Life, psychological hardiness in learning, learning motivation, and perceived functional value of business education. The relationships among the constructs were estimated by Structural Equation Modeling. The results demonstrate that psychological hardiness in learning and learning motivation have statistically significant positive impacts on students’ perceived Quality of College Life. The impacts are significantly stronger for students with higher assessments of the functional value of a business education. These findings suggest that universities could enhance the Quality of College Life and academic performance by offering programs to cultivate students’ psychological hardiness in learning and their learning motivation, and by providing them with objective information about the functional value of business careers.
