Salah satu cara untuk mengolah MB dalam larutan yaitu dengan fotokatalisis mengingat sederhana, cepat, dan mudah diregenerasi. Namun, cara ini memiliki kekurangan yakni waktu pemisahan yang lama. Penambahan sifat magnetik ke dalam material fotokatalis yang kemudian disebut fotokatalis magnetik dapat mengatasi kelemahan dari fotokatalis konvensional.

Abstract Experimental tests about cross-cultural differentiation of cognitive style conclude that East Asian and Western cognition differ. Tendencies described as East Asian include holism, non-linearity, expectation of change, relationalism, field dependence, causal pluralism, dialecticism, and a tolerance of contradiction. Cross-cultural psychologists generally refrain from discussing the intellectual history or cultural evolution of these differences, preferring to explain results on cognitive scales in terms of results on social scales assessed using present-day participants. The present article attempts to partially close this explanatory gap through detailed discussion of tendencies of East Asian cognitive style as represented in what is probably the most influential book in the history of East Asia, The Book of Changes. This study purports to show (a) that the content of the Yijing 易經 and its commentaries is best described in terms of the cognitive tendencies just mentioned, (b) that reading the Yijing activated those cognitive tendencies, and (c) that the Yijing attained prodigious influence on subsequent Chinese and East Asian cultures through four known mechanisms of cultural transmission. Informed by this case study, researchers of cross-cultural cognition may be positioned to develop a richer appreciation of the cultural representation and evolution of East Asian cognitive style in historical context.

This study examines the influence of culture on decision-making in multinational workgroups, specifically native English speakers and non-native English speakers of Asian descent. We use observational methods to provide additional insight into the different conversational patterns of group members of different cultural backgrounds and to understand how these patterns affect team dynamics. We used a four-by-four design to compare the interactions of groups composed of a majority of native-English speakers (and a minority of East Asian language speakers) and homogenous groups of ethnically diverse East Asian languages (and native speakers of English) to learn whether composition affects discourse style and contribution level. We found a significant difference in the number of turns taken by native-English speakers compared with those taken by non-English-speaking native speakers. The average number of overlaps and backchannels was also significantly higher than for native-speaking English speakers. This study has implications for those engaged in managing, training, or teaching heterogeneous groups consisting of members from the U.S. and East Asian countries. Managers, trainers, and teachers should ensure that those whose native language is East Asian are aware of the particular conversational behaviors that characterize this style of discourse. They should be educated about the specific conversational cues that might reap a deeper understanding of differences in discourse styles between the two participant groups.

Challenging the dichotomous cliché “East Asian medicine is all about qi, the Western medicine all about anatomy,” this paper attempts to uncover a style of practice within the historical landscape of East Asian medicine that does not draw on cosmological paraphernalia such as yin-yang, the Five phases and qi, but rather focuses on the materiality of the human body. This style of practice can be seen in medical areas such as surgical treatment, acupuncture, trauma care, first aid, obstetrics, military medicine, forensic medicine and anatomy, as well as in some doctors’ contemplation of anatomical structures of the human body. By examining related cases, this article explores the medical body of materials, structures and spaces as it was understood, experienced, and interpreted by historical East Asian actors. In conclusion, medical activities or cognitive practices of East Asian doctors based on the body materiality are quite noteworthy and should be deserved a consideration in the broader historical context of East Asia. As such, this style of practice can be distinguished from the cosmological thinking. Inasmuch as, the term “topological body” might be employed in referring the medical body.

The objective of this article is to show the effects of the use of Free Association Technique on the elicitation of brand emotions and functional associations across a Western and an East Asian culture as well as to identify and test underlying mechanisms. The use of Western techniques for eliciting brand emotions may prove challenging for marketers in East Asian markets because of the different styles of thinking and feeling of consumers in the West versus East Asia. This investigation focuses on the role of visual context (individual vs social), in which brands are presented when eliciting brand associations in the West and in East Asia. The study shows that elicitation context significantly influences the type of brand emotions and functional associations across two distinct cultures: Norway and Thailand. Consumers’ self-construal and thinking style mediate the effects of culture, as interdependent self-construal and holistic thinking explain more context-dependent brand emotions generated by Thai than Norwegian consumers. This research has important implications for studying and managing brand associations and emotions across markets. The traditional view of brands as possessing abstract, stable associations, and emotions should be reconsidered in the East Asian cultural context. Marketing managers should adapt established Western elicitation techniques to the characteristics of East Asian consumers to increase their validity.

AbstractIn “Normativity and Epistemic Intuitions” (NEI), Weinberg, Nichols and Stich famously argue from empirical data that East Asians and Westerners have different intuitions about Gettier-style cases. We attempted to replicate their study about the Gettier Car Case. Our study used the same methods and case taken verbatim, but sampled an East Asian population 2.5 times greater than NEI's 23 participants. We found no evidence supporting the existence of cross-cultural difference about the intuition concerning the case. Taken together with the failures of both of the existing replication studies (Nagel et al. 2013; Seyedsayamdost 2014), our data provide strong evidence that the purported cross-cultural difference in intuitions about Gettier-style cases does not exist.

Research on parenting styles and children’s developmental outcomes have been prominent in the parenting and achievement literature for decades and research shows that parenting style is not consistent across families from diverse backgrounds (Baumrind, 1971; Chao, 1994; Grusec, Goodnow, & Kuzcynski, 2000). Building on this research, this study examines Korean parenting and its influence on Korean-American achievement by examining the common factors across East Asian parenting ideologies, styles, and practices through the East Asian Parenting Model (EAPM) (Chao, 1994; Choi, Kim, Pekelnicky, & Kim, 2013; Darling & Steinberg, 1993). Perceptions about child development and learning and the changing and evolving mother-child relationship are patterns particularly explored in this study. Overall, this study purports important findings regarding evolving Korean parenting foundations affecting Korean-American achievement which add to the field of Asian-American achievement literature. These findings may help inform educators working within school settings about ways in which Korean parenting foundations influence the education of these children.

Abstract Diagnosing a gap in our knowledge on populist phenomena in East Asian democracies, especially the lack of attention paid to the region by comparative studies, the organisers of the online lecture series ‘Populism in East Asian Democracies’ (PinEAD) brought together small but substantial research on East Asia by inviting presentations by nine experts, three each on Japan, South Korea, and Taiwan. Their findings showed how different phenomena and actors analysed as populists in East Asian democracies are from those in Europe or the Americas. They also highlighted how heterogeneous the group of politicians referred to as ‘East Asian populists’ is. While, on an abstract level, most East Asian populists are similar, in that they appeal to voters discontented with the democratically elected ruling parties and executives and promise to govern in a way more favourable to ‘the people’, they do so in ways that differentiate them from the standard style of political campaigning and rhetoric in their respective country.

Ikumen, meaning fathers with small children who are--or look like they are--actively involved in childrearing are a new phenomenon in contemporary Japan, despite the prevalent images of patriarchic and absent fatherhood. But why and how did yesterday's notorious company soldiers turn into today's ikumen? This dissertation interrogates this supposedly drastic shift in the view and the conduct of fatherhood as a cultural practice on historical, political economic, and linguistic grounds. Drawing on fieldwork, mass media, and historical analysis, I explore how new styles of fatherhood have been constructed and how they embody broader social issues of gender, class, and modernity and globalization. Gender roles in the modern family since the late nineteenth century have been strained, and ikumen will allegedly liberate both men and women to achieve the ideal of "work-life balance" in a "gender-equal society." Examination of various genres of language, from metapragmatic comments to the advertising of nursery items, however, suggests that the ideology of gender roles is naturalized and "male features" are appropriated to lead men into the "female" sphere of the home. I argue that this discourse represents the heteroglossic nature of language, and that our speech, influenced by accustomed thoughts, paradoxically strengthens that discourse despite our intentions. Ikumen are not only connected to concerns about gender, but also are predicated on Japan's historical and ongoing fantasy of modernity and globalization. From the label ikumen, to state and local campaigns for male participation in childcare, to the use of terms of address for parents, the idealized West and its monolithic images of stylish and active fatherhood and romantic couplehood are covertly exploited. As a whole, the ikumen movement ends up creating an "imagined community," in which "globalism" is believed to help one obtain a more authentic and global "self" through childrearing. I argue that the ikumen movement presents the perpetual but concealed power hierarchy of modernity, and that Japan and Japanese people docilely appropriate this historical truth, institutionalizing the counterhegemony as the new hegemony and as a form of cultural capital in the context of a disturbingly low birthrate and a sluggish economy.

To keep pace with ubiquitous computing in all aspects of society, universities have invested heavily in off-the-shelf or in-house learning management systems, and teachers are being encouraged to seek ways in which to optimize the role of information and communication technology to support their teaching and learning activities; both on the campus and beyond campus borders. However, many students in residential universities are resistant to embracing CMC-mediated activities as an integral part of their coursework, and this attitude underscores the importance of understanding how these students are affected by the implementation of the new teaching and learning strategies associated with a 'blended learning' approach. This study explores a particular context in which discussion forums were deployed as a replacement to traditional face-to-face tutorial discussions. Research subjects (n=147), health psychology students at a South East Asian university, completed a Felder Soloman Index of Learning Styles (ILS) questionnaire before being assigned to online discussion forum groups of 8 or 9 students per group. During the 9 weeks of the tutorial assignment activity, student interactions in the discussion forums were monitored and transcripts of their postings and replies were analysed and coded. Quantitative data from attitude survey MCQs, grades, peer ratings and usage statistics, as well as qualitative data from attitude survey open-answer questions and one-to-one interviews, were also gathered and analysed. The findings identified a number of weaknesses and drawbacks of using discussion forums: notably that students who felt uncomfortable about expressing their opinions in discussion forums also had difficulty understanding what was being communicated in the postings and didn't trust their group members; students who were identified as having a moderate to strong 'Sequential' cognitive learning style preference were more likely to indicate that they had a difficult time working in the discussion forums; and students who were identified as having a moderate to strong 'Active' cognitive learning style preference tended to make fewer forum postings. Nevertheless, since the scope of the information quoted, and opinions generated, in the discussion forum postings was noticeably greater than what was generally brought up in face-to-face discussions, and because the majority of students worked independently and responsibly, this particular blended learning approach was deemed a success by the course instructor. However, the author puts forward a number of recommendations to instructional designers, practitioners and students for designing, setting up and running a similar but more flexible approach as an alternative to traditional large-class face-to-face tutorial discussions.

The art of reading and its application to knowledge acquisition and innovation by elites have been largely neglected by historians of print culture and reading in late imperial China (1368-1911). Unlike most studies, which are concerned more with the implied reader and individual reading experience, the present study assumes that the actual reader and the social, cultural and epistemic dimensions of reading practices are the central issues of a history of reading in China. That is, while the art of reading was internalized by the individual, his learning and application of it had social, cultural and epistemic features. At a time when secular reading practices in Renaissance England were informed by Erasmian principles, Ming literati, regardless of their different philosophical stances, were being trained in an art of reading proposed by Zhu Xi (1130-1200), whose Neo-Confucian philosophy had been esteemed as orthodox since the fourteenth century. Transformations and challenges in interpreting and applying his art did not hinder its general reception among elite readers. Its common employment determined the practitioner’s epistemic frame and manner of knowledge innovation. My dissertation consists of five chapters bracketed with an introduction and conclusion. Chapter One discusses Zhu’s theory of reading and the implied pattern of acquiring and innovating knowledge, based on a careful reading of his writings and conversations. Chapter Two describes the transmission of Zhu’s theory from the thirteenth to the seventeenth centuries. During its transmission, Zhu’s art was reedited, rephrased, and even readapted by both government agencies and individual authors with different intentions and agendas. Chapter Three focuses on the reception of Zhu’s theory of reading by 1500 and argues that the moral end of reading eventually triumphed over the intellectual one in early Ming Confucian philosophy. Chapter Four explores the affinity of Ming philosophers of mind with Zhu’s theory in their reading concepts and practices from 1500 to the mid-seventeenth century. Despite their attempts to separate themselves intellectually from the Song tradition, Ming philosophers of mind followed Zhu’s rules for reading in their intellectual practices. Chapter Five outlines the reading habits and knowledge landscape based on a statistical survey of extant Ming imprints. Despite some deviations, the Ming reading habits and knowledge framework largely accorded with Zhu’s theory and its Ming adaptations. The continuity of reading habits from Zhu’s time to the seventeenth century, I conclude, inspires us to rethink the Ming apostasy from the Song tradition. The particularity of scholarly knowledge acquisition and innovation in Ming-Qing China by the eighteenth century was not invented by Ming-Qing scholars but anticipated by Zhu through his theory of reading. With respect to late imperial China, the history of reading, together with the history of knowledge, is yet to be fruitfully explored. With this dissertation, I hope to be able to make a contribution to the understanding of the East Asian orthodox habit of reading as represented by Zhu’s admirers. By placing my investigation in the context of the history of knowledge, I also hope to contribute to the understanding of the relationship of reading to the way that knowledge evolved in traditional China. Intellectual historians tended to consider the Ming Confucian tradition as having broken off from the Cheng-Zhu tradition, but at least in reading habits and practices Ming elite readers perpetuated Zhu’s theory of reading and the knowledge framework it implied.

The purpose of this study was to compare Far Eastern influences on Western women's dress as represented in both a high fashion and mass fashion magazine between 1910 and 1925. Vogue was selected as the high fashion magazine and Ladies Home Journal as the mass fashion magazine. The questions that were addressed were: was there a difference in the influence of the Far East on high fashion styles and mass fashion styles, was there a time lapse between the appearance of fashion styles influenced by the Far East within Vogue and Ladies Home Journal, and was the trickle-down theory applicable when examining Far Eastern influence on high fashion styles and mass fashion styles. The data were collected by conducting a content analysis of both the written and visual material within Vogue and Ladies Home Journal. For each magazine the January, April, July, and October issues were examined, totaling a 128 issues between the years 1910 and 1925. The written examples found within both magazines were placed into three categories; Chinese, Japanese, and Far Eastern/Oriental. Visual examples found were placed into three categories also; Chinese, Japanese, and Combination. An example of Far Eastern influence on written or visual material was based on predetermined guidelines. It was hypothesized that there would be a difference in the frequency of Far Eastern influence seen in high fashion styles as represented in Vogue and mass fashion styles as represented in Ladies Home Journal between 1910 and 1925. The sign test was used to compare the two samples Vogue and Ladies Home Journal and test this hypothesis. It was determined that there was not a significant difference found in either the written or visual material therefore this hypothesis was rejected. The second hypothesis was that there would be a difference in the period of introduction of fashion styles influenced by the Far East between Vogue and Ladies Home Journal. There was no apparent difference between the period of introduction of fashion styles influenced by the Far East in Vogue and Ladies Home Journal between 1910 and 1925 when examining total frequencies of both written and visual material. Some differences were evident when examining categorical breakdowns which led to neither the acceptance or rejection of the hypothesis due to the differing results.

In this presentation, I will show that various multimodal resources—such as utterance, prosody, rhythm, schematic images, and bodily reactions—may integratively contribute to the holistic achievement of poeticity. By incorporating the ideas from “ethnopoetics” (Hymes 1981, 1996) and “gesture studies” (McNeill 1992, 2005), I will present a plurimodal analysis of naturally occurring interactions by highlighting the interplay among the verbal, nonverbal, and corporeal representations. With those observations, I confirm that poeticity is not a distinctive quality restricted to constructed poetry or “high” culture, but rather an endowment to any kind of natural discourse that is co-constructed by various semiotic resources. My claim specifically concerns a renewed interest in an ethnopoetic kata ‘form/ shape/ style/ model’ embraced as performative “habitus” among Japanese speakers (Kataoka 2012). Kata, in its broader sense, is stable as well as versatile, often serving as an organizational “template” for performance, which at opportune moments may change its shape and trajectory according to ongoing developments. In other words, preferred structures are not confined to an emergent management of performance, but should also incorporate culturally embedded practices with immediate (re)actions. In order to promote this claim, I explore a case in which mutually coordinated performance is extensively pursued for sharing sympathy and camaraderie. Such a kata-driven construction was typically observed in a highly involved, interactional interview about the Great East Japan Earthquake, in which both interviewer and interviewee were recursively oriented and attuned to the same rhythmic and organizational pattern consisting of an odd-number of kata. Based on these observations, I argue that indigenous principles of organizing discourse are as crucial as the mechanisms of conversational organization, with the higher-order, macro cultural preferences inevitably infiltrating into the micro management of spontaneous talk.

The article examines materials of the burial complexes belonging to representatives of the highest aristocracy of Northern Qi (550-577). The design, burial inventory, plots and style of wall paintings in these burials are uniform, which indicates the strict regulation of the funeral rites. All the materials reflect the polyethnicity of the Chinese-Xianbi population of the Northern Qi (and in particular, the elites) and its intensive external contacts (with Turks, Rouran, Sogdians). The art presented in the tombs discussed demonstrates a fusion of ideas and images, originated from the Hun tradition and formed under the influence of Buddhism, as well as borrowed during the contacts with steppe nomads and the settled population of Central Asia.

The article studies S. V. Rachmaninov’s famous work – “Elegie” op. 3. The background of the composer’s tragic perception of the world, determined by his worldview in general, influenced his running out of the limitations of elegy as the genre model. For instance, the concept of “tragic farewell” is one of the constants in the composer’s works and his perspective on life. The article highlights similarities and common points between the works of S. V. Rachmaninov and the elegies of French composers, creations of P. I. Tchaikovsky, the poetic work of V. K. Trediakovsky, as well as the ancient prototype of the genre – the chant of the double flute of Asia Minor. Moreover, the study shows the presence in the worldview of S. V. Rachmaninov the “East theme” and some elements of the musical language of P. I. Tchaikovsky, creatively revisited and integrated as a component of his artistic style.

This brief shows how ADB is engaging audiences through storytelling to better highlight the impact of its work in Asia and the Pacific, share knowledge, and communicate complex ideas in a creative and effective way. It explains why it adopted conversational TED-style talks to deliver stories and how these resonate with audiences. It outlines the components of good stories and the importance of making them sound authentic and easy to understand. It analyzes how integrating storytelling into ADB’s communications strategy is helping build trust, share experiences and best practices, and harness knowledge in order to better address the region’s critical challenges.
