Recent work has improved recommendation models remarkably by equipping them with debiasing methods. Due to the unavailability of fully-exposed datasets, most existing approaches resort to randomly-exposed datasets as a proxy for evaluating debiased models, employing traditional evaluation scheme to represent the recommendation performance. However, in this study, we reveal that traditional evaluation scheme is not suitable for randomly-exposed datasets, leading to inconsistency between the Recall performance obtained using randomly-exposed datasets and that obtained using fully-exposed datasets. Such inconsistency indicates the potential unreliability of experiment conclusions on previous debiasing techniques and calls for unbiased Recall evaluation using randomly-exposed datasets. To bridge the gap, we propose the Unbiased Recall Evaluation (URE) scheme, which adjusts the utilization of randomly-exposed datasets to unbiasedly estimate the true Recall performance on fully-exposed datasets. We provide theoretical evidence to demonstrate the rationality of URE and perform extensive experiments on real-world datasets to validate its soundness.

Talpid3-Binding Centrosomal Protein Cep120 Is Required for Centriole Duplication and Proliferation of Cerebellar Granule Neuron Progenitors

PLoS ONE (2014)

Chuanqing Wu Mei Yang Juan Li Chengbing Wang Ting Cao

Granule neuron progenitors (GNPs) are the most abundant neuronal type in the cerebellum. GNP proliferation and thus cerebellar development require Sonic hedgehog (Shh) secreted from Purkinje cells. Shh signaling occurs in primary cilia originating from the mother centriole. Centrioles replicate only once during a typical cell cycle and are responsible for mitotic spindle assembly and organization. Recent studies have linked cilia function to cerebellar morphogenesis, but the role of centriole duplication in cerebellar development is not known. Here we show that centrosomal protein Cep120 is asymmetrically localized to the daughter centriole through its interaction with Talpid3 (Ta3), another centrosomal protein. Cep120 null mutant mice die in early gestation with abnormal heart looping. Inactivation of Cep120 in the central nervous system leads to both hydrocephalus, due to the loss of cilia on ependymal cells, and severe cerebellar hypoplasia, due to the failed proliferation of GNPs. The mutant GNPs lack Hedgehog pathway activity. Cell biological studies show that the loss of Cep120 results in failed centriole duplication and consequently ciliogenesis, which together underlie Cep120 mutant cerebellar hypoplasia. Thus, our study for the first time links a centrosomal protein necessary for centriole duplication to cerebellar morphogenesis.

The rational modem identity and its growth in life world

Gansu Theory Research (2005)

Chengbing Wang

This paper claims that the rational modern identity should play a key role in building the harmonious society. The paper makes it clear that the idea of rational modern identity should deal with the reasonable tension between identity and the crisis of identity, the idea of rational modern identity may recover and maintain the essential constitutes in the identity; the idea of rational modern identity should represent the mutual-making relations between the “self” and the “others”. The paper is also exploring the issue of breeding the rational modern identity in the context of life world, emphasizing the roles the community building, social communication and the institutional construction may play in this process.

Scholarly Responses to “Who Leads, Who Follows?”

Beijing international review of education (2023)

Chengbing Wang Liz Jackson Kwok Kuen Tsang Colin W. Evers Wei Zhao

Who Leads, Who Follows? "Critical Review of the Field of Leadership Studies" by Professor Michael A. Peters, offers one of the clearest and most complete discussions of "critical leadership studies" in the twenty-first century.It deeply considers many of its most important issues, including its evolution and its path forward, its most important paradigms, and its many transformations in the hands of a variety of scholars.The perspective and vision that he brings to bear in the article and its wide ranging discussions of the many relevant contemporary issues that it concerns are deeply thought-provoking.Some of the scholars mentioned by Professor Peters in the paper in question are certainly familiar to Chinese scholars, including Max Weber, while many others will be either little known or have not as yet been examined within the framework of educational philosophy in China.As a professor of philosophy in China, I would like to express the following three comments:First, Professor Peters emphasizes three areas in the "leadership in the Twenty-First Century."The first is "Leadership, multipolarity, and the production of global public goods," the second is "Leadership in the Biodigital Future," and the third is "The Ecological-System Model of Leadership."He individually isolates these three areas because it allows him to articulate and highlight important issues and challenges that leadership education in the 21st century must be aware of and manage.In my humble opinion, no matter whether it is a question of public goods, of the biodigital future, or the ecology-system, each of these areas demands our attention precisely because they are without doubt the urgent issues of educational philosophy confronting China today, and they equally deserve to be seriously considered and discussed by Chinese scholars.Second, in his essay, Professor Peters fully displays a remarkable presentation of the Marxist philosophy of leadership.In Chinese philosophy classes, we often deal with Marxist topics concerning the relationship between the masses and the leaders, between the heroes and the masses, and between the times and the heroes, but in most cases, the discussions take place within the Beijing International Review of Education 5 (2023) 51-91 53

Man, as a Product of the Coagulation of Multilevel Needs ─ A Review of the Western Scholars' Theory of Human's Needs

Journal of The Northwest Normal University (2001)

Chengbing Wang

Modern Western scholars, with Maslow and Fromm as their representatives, have put forth the theory of human needs. its basic concept is that man's needs are resulted from and determined by his subsistence conditions; man's needs may fall into different levels, and between these levels of needs is there an essential internal relation. And besides,on the basis of an all-round examination of multiple human needs, those modern Western scholars proceed to explore therelationships between man's multiple needs and man's full development.
