School leaders are constantly challenged by diverse students and conflicting interests between faculty and staff. They are often called upon to make sense of ethical quagmires, where rules might conflict with desired outcomes or personal values clash with professional obligations. Negotiating these dilemmas can be challenging, but democratic ethics can offer an effective process to work through them. Drawing from the writings of John Dewey, Leading Through the Quagmire advocates his notion that democracy is an appropriate response to the multitude (...) of conflicting interests, needs, and values in educational settings. Moreover, Enomoto and Kramer propose an inquiry method to harness democratic ethics for engaging in fair deliberation and conflict resolution. This book provides the foundation for understanding tensions, as well as the methods and applications to navigate through them. Stories and examples are provided to enable readers to understand such terms as utilitarianism, ethical tensions, religious attitudes, and eco-feminism in meaningful ways. (shrink)

This paper presents a communication protocol to reach consensus. In our setting, every player has asymmetric information and evaluates a fixed event on his information. According to the protocol, the sender sends non-partitional messages that he believes the event with a probability of at least his evaluation. We show that the posteriors for the event must be equal among the players after the communication. Journal of Economic Literature Classification: C62, C78.

「和歌」「声」「文字」という表現メディアに着目し宣長思想と教育との関わりを検証。幼児教育への応用についても検討する。.

Funded by the U.S. Department of Education, the Baltimore Learning Community (BLC) project established a networked electronic learning community through the use of high-quality digital science and social studies resources and high-speed networking. The project will enable science and social studies teachers to access images, text, Web sites, and full motion video via high-speed connections to the Internet. Extending such multimedia configurations into urban schools has facilitated a rethinking of teaching and learning in content classes as well as a reconsideration (...) of how media and method are integrated. It facilitates teacher engagement in designing authentic classroom instruction framed by performance assessments and links project teachers and school site coordinators through a client server, thus promoting a network of teachers and students engaged in learning across schools. However, such a project is not without its challenges—human as well as technological. This article discusses the BLC project identifying technology possibilities, current situational constraints, and implications of creating networked learning communities across disciplines and beyond school walls.

IntroductionPrevious studies on metacognitive ability were explored using self-report questionnaires that are difficult to adequately measure and evaluate when the capacity for self-reference is undeveloped. This study aimed to validate the Congruency-based Metacognition Scale to measure metacognition and the feeling of confidence abilities and to investigate the development of metacognition during adolescence.MethodsThe CMS was administered to 633 child–parent pairs in Japan. The CMS metacognition score was assessed based on congruency scores between the self-report of the child from a third-person perspective (...) and the parent’s report from the first-person perspective. The CMS self-judgment accuracy score was assessed by the congruency scores between the children’s self-report from the 1PP and 3PP. For both measures, the more distant the 3PP on the self-report was from the 1PP on the parent’s report and child self-report means low ability. An exploratory factor analysis was conducted to examine construct validity and then a confirmatory factor analysis was used. Criterion validity was examined by calculating Pearson’s correlation coefficients with scores on the Beck Cognitive Insight Scale and Autism Quotient. We used intraclass correlation and Cronbach’s alpha to examine the test–retest and internal consistency reliability.ResultsBased on the results of the EFA and CFA, we adopted one factor structure with five items. The CMS metacognition and CMS self-judgment accuracy showed evidence criterion validity, exhibiting significant correlations with the BCIS self-reflectiveness and self-certainty scores, respectively. Regarding to the AQ, only the CMS metacognition score had significant correlations with the social skills and total scale score. The test–retest reliability showed adequate. Adolescents were found to have significantly lower metacognitive ability compared to young adults.ConclusionCMS could be a valid and reliable measure to examine metacognitive abilities for adolescents.

Although initiation of DNA replication is considered to be highly coordinated through multiple protein–DNA and protein–protein interactions, it is poorly understood how particular locations within the eukaryotic chromosome are selected as origins of DNA replication. Here, we discuss recent reports that present structural information on the interaction characteristics of the archaeal orthologues of the eukaryotic origin recognition complex with their cognate binding sequences.1,2 Since the archaeal replication system is postulated as a simplified version of the one in eukaryotes, by analogy, (...) these works provide insights into the functions of the eukaryotic initiator proteins.
