A stochastic prey-predator system in a polluted environment with Beddington-DeAngelis functional response is proposed and analyzed. Firstly, for the system with white noise perturbation, by analyzing the limit system, the existence of boundary periodic solutions and positive periodic solutions is proved and the sufficient conditions for the existence of boundary periodic solutions and positive periodic solutions are derived. And then for the stochastic system, by introducing Markov regime switching, the sufficient conditions for extinction or persistence of such system are obtained. (...) Furthermore, we proved that the system is ergodic and has a stationary distribution when the concentration of toxicant is a positive constant. Finally, two examples with numerical simulations are carried out in order to illustrate the theoretical results. (shrink)

Teachers involved in English as a foreign language (EFL) teaching play a significant role in the process of moving toward educational equity. Teacher cognition is very influential in shaping teacher practice and thus affects students’ academic performance. However, although the role of EFL teachers as equity agents has been recognized, few studies have explored EFL teachers in-depth in terms of their cognition and practice. Moreover, no review studies have given sufficient attention to the task of elucidating the interrelations between EFL (...) teachers’ cognition and practices in the context of educational equity. Therefore, to provide a novel perspective and generate fresh insights into this research field, the current study attempts to explain the connotations of these constructs, highlights the interplay between EFL teachers’ equity-oriented cognition and practice, and identifies both experiential and contextual factors that might have an effect throughout the teaching process. Finally, practical implications and directions for teachers, researchers, policy-makers, and social justice leaders who are interested in actualizing education as a means of attaining equity are also discussed.

The previous literature analyzed the widespread imitative innovation of Chinese enterprises from various perspectives, including enterprises' rational choice of cost-gain, property rights system, human capital and policy environment. However, this paper provides a brand-new perspective on government subsidies for the reasons behind the imitative innovation of enterprises. According to the statistics from Chinese enterprise-labor matching, we found that government subsidies stimulated enterprises to make “imitative innovation” through patent purchase rather than independent R&D. Government subsidies were used for low-risk “imitative innovation” (...) because of enterprises' rent-seeking behavior, low R&D ability and the review of government subsidy projects. Based on the above conclusions, this paper suggests that the government should reduce or withdraw its intervention in enterprise innovation and implement the post-subsidy and post-evaluation mechanism for government-subsidized programs.

Previous research has established that people can implicitly learn chunks, which do not require a memory buffer to process. The present study explores the implicit learning of nonlocal dependencies generated by higher than finite-state grammars, specifically, Chinese tonal retrogrades and inversions , which do require buffers . People were asked to listen to and memorize artificial poetry instantiating one of the two grammars; after this training phase, people were informed of the existence of rules and asked to classify new poems, (...) while providing attributions of the basis of their judgments. People acquired unconscious structural knowledge of both tonal retrogrades and inversions. Moreover, inversions were implicitly learnt more easily than retrogrades constraining the nature of the memory buffer in computational models of implicit learning. (shrink)

Educational assessments tests are often constructed using testlets because of the flexibility to test various aspects of the cognitive activities and broad content sampling. However, the violation of the local item independence assumption is inevitable when tests are built using testlet items. In this study, simulations are conducted to evaluate the performance of item response theory models and testlet response theory models for both the dichotomous and polytomous items in the context of equating tests composed of testlets. We also examine (...) the impact of testlet effect, length of testlet items, and sample size on estimating item and person parameters. The results show that more accurate performance of testlet response theory models over item response theory models was consistently observed across the studies, which supports the benefits of using the testlet response theory models in equating for tests composed of testlets. Further, results of the study indicate that when sample size is large, item response theory models performed similarly to testlet response theory models across all studies. (shrink)

This article describes how phenomenography, as a qualitative research method, can be used to tackle key challenges in science education. It begins with an overview of the development of phenomenography. It then describes the philosophical underpinnings of phenomenographic inquiry, including ontological and epistemological roots, and its unique second-order perspective. From theoretical background to practicality, the paper uses rich examples to describe in detail the procedures of conducting a phenomenographic study, including sampling and data collection, analyzing phenomenographic data, and communicating key (...) findings. The paper concludes by showing how the phenomenographic method can be used to develop students’ conceptual understanding of scientific concepts, to inform effective instructional design in science teaching, and to identify and improve evidence-based factors in student learning to enhance learning outcomes in science.

Previous studies showed inconsistent results on the association between searching for calling and its psychosocial functioning outcomes. The link of searching for calling to its psychosocial functioning outcomes may be influenced by the presence of calling because the search for and presence of calling can co-exist within individuals. Thus, the present study employed a person-centered method to identify subgroups combining the search for and presence of a calling and then explore the identified profiles' differences in work meaning and job satisfaction. (...) Study participants were Chinese kindergarten teachers. Latent profile analysis revealed four different groups: actively maintaining calling, unsustainable calling, moderately increasing calling, and actively increasing calling. Subsequent analyses showed notable differences across the four groups on work meaning and job satisfaction. Participants in profile 1 with both the highest searching for and presence of calling would experience more work meaning and job satisfaction than those in the other profiles whose strengths of searching for and presence of calling were relatively low. Participants in profile 4 had higher searching for and presence of calling than those in profile 3, and they experienced more meaningfulness at work and were more satisfied with their job. These findings indicate that actively searching for calling is closely associated with more work meaning and job satisfaction among people who already perceive intensive calling. Implications, limitations, and future directions of the results are discussed. (shrink)

This article examines online identity practices of Chinese doctors mediated through borrowed linguistic resources in a leading medical app. Setting against rapid societal changes in China which open up traditionally ‘powerful’ professions to market competition, and the development of a booming digital economy, this app and its semiotic work drawing on Chinese Internet vernacular, I will argue, offer a fascinating lens to probe into the highly dynamic online discursive practices in contemporary China. Drawing on the notions of entextualization and resemiotization, (...) I will trace and analyse the patterned ways in which pre-existing linguistic resources are creatively reworked by the app to achieve new identity-making purposes. Situating the changes of the field of healthcare in China within a worldwide shift towards neoliberal ideologies and practices, I will also briefly discuss how the emergence of such new social space in digital settings may impact the production and communication of health knowledge and services in China.

As observed by both western and Chinese scholars, despite the cultural and historical distance between them, the works of Confucius and J. L. Austin (together with other scholars of speech act theory) share similar views on the performative dimensions of language. Speech act theory underscores how utterances constitute actions instead of reporting inner mental states of the speakers, while Confucian texts also draw attention to the embeddedness of language in the wider contexts of personal affairs and social order. In this (...) article, we conduct a detailed comparison of the two to demonstrate that their views on language and communication, although sharing some important concerns, differ significantly in two main aspects: (1) The relationship between one’s ‘internal’ cultivation and ‘external’ behaviours; (2) The conceptualization of language and ethics. In conclusion, we discuss the implications of a Confucian outlook for the study of language and communication and point out some directions for future research. (shrink)

Mutation and lateral transfer are two categories of processes generating genetic diversity in prokaryotic genomes. Their relative importance varies between lineages, yet both are complementary rather than independent, separable evolutionary forces. The replication process inevitably merges together their effects on the genome. We develop the concept of “open lineages” to characterize evolutionary lineages that over time accumulate more changes in their genomes by lateral transfer than by mutation. They contrast with “closed lineages,” in which most of the changes are caused (...) by mutation. Open and closed lineages are interspersed along the branches of any tree of prokaryotes. This patchy distribution conflicts with the basic assumptions of traditional phylogenetic approaches. As a result, a tree representation including both open and closed lineages is a misrepresentation. The evolution of all prokaryotic lineages cannot be studied under a single model unless new phylogenetic approaches that are more pluralistic about lineage evolution are designed. (shrink)

Zhuangzi is one of the great figures in the history of ancient Chinese thought. While Laozi and Zhuangzi are ranked together as the founders of Daoism, it is in fact primarily Zhuangzi who, as the worthy adversary of the Confucian school of Confucius and Mencius, has been the greatest influence in politics, culture, and thought. While this influence has had its negative aspects, its positive side has predominated. How to dialectically and historically evaluate Zhuangzi properly is a very important problem.

The Yogācāra School presents the seventh consciousness as the internal mental faculty of the sixth consciousness. According to the Hīnayāna tradition, the internal faculty is called manas, so the complete compound word referring to the seventh consciousness is manovijñāna. Thus, in the Yogācāra system the seventh and sixth consciousnesses are both named manovijñāna. In order to resolve the confusion of the homonyms, one of them must be adjusted. Based on the Tibetan term, nyon yid rnam par shes pa, some scholars (...) recently claimed that the seventh consciousness could be called kliṣṭamanas. However, in the Cheng Weishi Lun, Xuanzang proposed that the seventh consciousness is also reasonably named akliṣṭamanas when referring to the pure Buddha, and therefore it is better to simply term the seventh consciousness “manas”. On the other hand, some Indian ancient Yogācāra theorists suggested that the word manovijñāna should be used to name the seventh consciousness, while the sixth consciousness would in that case be called dharmavijñāna. However, that solution was rejected by Cheng Weishi Lun. Through contextual analysis, utilizing the method of the Indian Śāstra of Vaiyākaraṇa, this article puts forward an innovative way to solve the difficult problem of homonymity: denoting the seventh consciousness as pradhānamanovijñāna based on the unique meaning of manas advocated by Yogācāra School itself.

Based on implicit leadership theory, we examine the congruence effect of leader-follower power distance orientation on follower trust in a supervisor and work engagement, which in turn influences employees’ task performance. Results of Polynomial regressions on 526 dyads supported the congruence effect hypothesis. The results show that (1) the congruence of leader-follower power distance orientation leads to better performance; (2) under the condition of congruence, Subordinate task performance is higher when leader-follower power distance orientation matching in low-low ratings congruence than (...) it is in high-high ratings congruence; (3) under the condition of asymmetrical incongruence, the follower had higher task performance when a leader’s power distance orientation is lower than a follower’s power distance orientation; (4) trust in supervisor and the work engagement mediates the effect of congruence of leader-follower power distance orientation on employees’ task performance; (5) trust in supervisor also mediates the effect of congruence of leader-follower power distance orientation on employees’ work engagement.

We investigate the role of legitimacy in setting organizational goals as a way to address the potential “dark,” unethical side of organizational goal setting. Coupling qualitative and quantitative research methods to better understand legitimacy in goal setting, we first induce novel hypotheses based on observed practice and then provide survey evidence to test the performance implications. Study 1 reports findings based on interviews with twenty-two company executives. We identify attention to goal credibility, prioritization of stakeholders directly involved in the goal’s (...) attainment when setting goals, and communication openness regarding goals, as well as their combination, as being important to organizational performance outcomes. Study 2 determines whether these three practices and their interaction predict performance using a survey conducted with 522 companies across four countries. Among other findings, we contribute to the organizational goal setting literature by showing that higher organizational performance is associated with the amount of priority given to the key actors (typically employees) directly involved with the goal’s attainment. We also find a positive interaction between attention to goal credibility, key actor (employee) importance, and communication openness on financial performance and non-financial goal attainment. Our work takes an initial step toward understanding how organizations can better shape the legitimacy of organizational goals for improved organizational performance and reduced unethical behavior.

This study addresses the question whether corporate social responsibility (CSR) matters in Asian Emerging Markets. Based on CSR scores compiled by Credit Lyonnais Securities (Asia), we assess the CSR performance of major Asian firms over a period of 3 years, from 2001 to 2004. The results show that there is a positive and significant relation between CSR and market valuation among Asian firms. We further find that CSR is positively related to the market valuation of the subsequent year. More importantly, (...) Asian firms are rewarded by the market for improving their CSR practice.

Drawing upon a developmental perspective, we investigated the differences in power acquisition between only and non-only children as well as the mediating role of cooperative and competitive orientations and the moderating role of dependency on parents. To test our hypotheses, we conducted two field studies in 155 part-time Master of Business Administration students and 375 senior students. Results showed that: non-only children were more likely to achieve higher rank at work than only children; only children were less likely than non-only (...) children to acquire power in organizations because they scored lower in cooperative orientation; however, the mediating effect of competitive orientation was not significant; the difference in cooperative orientation between only and non-only children was smaller when dependency on parents was high, whereas it became larger when dependency on parents was low. Our research contributes to the understanding of how family structure influences individual power acquisition. (shrink)

The importance imposed on corporate social responsibility is greater in developed economies than in emerging markets. The pressures from various stakeholder groups on the CSR are expected to have substantial spillover impact on companies domiciled in emerging economies that obtain revenues from companies in developed economies. Based on the data from 1,330 listed companies in China, the largest emerging economy in the world, this study provides evidence that the CSR performance of China firms is positively related to the degree of (...) their internationalization, and such a positive association is less pronounced for state-owned enterprises. Our findings support the hypothesis that internationalized companies in emerging economies are motivated to improve their CSR practices to address concerns from their importers or outsourcers in developed economies.

This paper evaluates the Hong Kong approach to consent regarding the forgoing of life-sustaining treatment for incompetent elderly patients. It analyzes the contextualized approach in the Hong Kong process-based, consensus-building model, in contrast to other role-based models which emphasize the establishment of a system of formal laws and a clear locus of decisional authority.Without embracing relativism, the paper argues that the Hong Kong model offers an instructive example of how strategic ambiguities can both make good sense within particular cultural context (...) and serve important moral goals.

Space being the precondition for human existence, human perception and experience vary responding to different spaces. Modern urban dwellers live in urban space where they seem to have much space mobility but end up living in a homogenized concrete jungle. This fact has influenced, if not defined, modern urban dwellers’ life experience and caused their anxieties about such an existence. However, wilderness, as opposed to urban space, is not merely a type of space, but a way of existence relating to (...) diversity, freedom, and healthy savagery. Civilizational evolution explains the change of human perception of wilderness from fear and desire to conquer to longing and affection, and in this sense the history of the evolution of space perception is also a history of civilization because space and culture are entwined and the more diversified the types of human living space, the more diversified their existences. In the contemporary world, the significance of wilderness not only lies in its resistance to the aforementioned homogenized, unidimensional, urban human existence, but the civilization of wilderness points to a new form of civilization that is intrinsically different from technological civilization for whose disease the civilization of wilderness per se may serve as a possible remedy.

Teachers' emotional states such as optimism and commitment have long been approved influential in second/foreign language education. Although many correlational investigations have been conducted on teacher optimism and commitment, their interaction and kinship with teachers' work engagement have been largely ignored in the literature. Considering this situation, the present mini-review aims to present the theoretical underpinnings, definitions, dimensions, and conceptualizations of these three important variables taken from positive psychology. Moreover, the present review can offer a number of practical implications for (...) EFL teachers, teacher educators, program designers, school principals, and L2 researchers, and raise their awareness of the impact of inner emotions on teachers' academic performance. Finally, research gaps and future directions are provided for eager researchers to run similar and complementary studies in EFL contexts. (shrink)

Multiple goals balancing is an important but not yet fully validated dimension of complex problem solving (CPS). The present study used process data to explore how solvers clarify goals, set priorities, and balance conflicting goals. We extracted behavioral indicators of goal pursuit from the log data of 3,201 students on the third subtask of the “Ticket” task in the PISA 2012 CPS test. Cluster analysis was used to identify 10 groups that varied in goal pursuit behavior. Logistics and least-squares regression (...) analysis were used to explore how goal pursuit affected task scores and CPS proficiency. The results showed that competent solvers clarified goals and weighed priorities more effectively. They also made trade-offs between conflicting goals. The importance of theoretically-driven log data analysis and coping strategies in the face of multiple goals conflict scenarios was discussed. (shrink)

Düşünce tarihi, geçmişten gelen birikimin katkısıyla ilerlemektedir. Bu bakımdan, ardıl olan düşünürlerin, geçmişteki filozoflarla olan hesaplaşmalarını incelerken titiz davranmak gerekmektedir. Düşünürlerin öncelleriyle olan bağı dikkatli biçimde irdelendiğinde, aralarında bütünüyle bir uyuşmazlık olmadığı görülecektir. Bu konuya örnek olarak Rousseau ve Nietzsche’nin düşüncelerini gösterebiliriz. Nietzsche’ye baktığımızda, onun bazı eserlerinde Rousseau’nun düşüncelerini sert bir dille eleştirmiş olduğunu görürüz. Bununla birlikte, Nietzsche’nin felsefesi bütünlüklü olarak incelendiğinde, her iki filozofun düşüncelerinin örtüştüğü pek çok nokta bulunmaktadır. Örneğin, Rousseau’nun varsaydığı biçimiyle doğa durumundaki insan, güçlü ve kendi (...) kendine yeterlidir; her türlü kötülük toplumsallıktan, ya da daha yerinde bir ifadeyle, toplumsallığın getirdiği eşitsizlikten doğar. Nietzsche’nin düşüncelerine baktığımızda, yine doğanın olumlandığını görürüz; ancak doğa – ve dolayısıyla doğal haliyle insan- dehşetengiz bir çehreye de sahiptir. Bu konu, her iki filozofun görüşlerinde birbirleriyle olan uyumlarına bir örnek oluşturur. Çalışmamızdaki temel çabamız, söz konusu iki düşünürün insan doğası merkezinde gelişen görüşlerinde özellikle birbirleriyle örtüşen noktalara dikkat çekmektir. Burada, Nietzsche ve Rousseau arasında birtakım bağdaşma noktalarının gösterilmesi, insanın doğası gereği iyicil bir varlık olduğuna ilişkin olumlu çıkarımların naif bulunarak hafife alınmasına yönelik bir karşı çıkış da barındırmaktadır. Çünkü toplumsal yaşamda süregelen adaletsizliklerin sona erdirilmesi için mücadele edilmesinde, insanın kendi türdeşlerini doğası gereği iyi varlıklar olarak kavraması önemli bir etkendir. (shrink)
