Angle is an important concept in geometry. Young children have difficulty separating angle size from other dimensions such as the length of angle sides, perhaps due to whole-object bias in word learning. The present study used the pre-test–training–post-test design to investigate the effectiveness of two ways of separating angle from angle size in 3–6-year-old Chinese preschoolers. A total of 228 children were given a pre-test and 219 of them failed the crucial test. 168 of the 219 children were present at (...) school during the training phase and were randomly assigned to three groups: the “toma” group, which received training to call the whole angle figure as “toma” and angle size as angle size; the “angle/angle size” group, which received the training of separating “angle” from “angle size”; and the control group, which used “angle size” alone to represent both the overall angle figure and angle size. Results showed that the “toma” group improved significantly more than the other two groups, the latter of which did not differ from each other. These results suggest that it is insufficient to have two separate words/phrases for children to learn to differentiate angle from angle size, perhaps due to their shared usage of the word angle. Instead, the use of a novel term is necessary and sufficient to improve learning. Implications for preschool education are discussed. (shrink)

We describe Peirce’s 1903 system of modal gamma graphs, its transformation rules of inference, and the interpretation of the broken-cut modal operator. We show that Peirce proposed the normality rule in his gamma system. We then show how various normal modal logics arise from Peirce’s assumptions concerning the broken-cut notation. By developing an algebraic semantics we establish the completeness of fifteen modal logics of gamma graphs. We show that, besides logical necessity and possibility, Peirce proposed an epistemic interpretation of the (...) broken-cut modality, and that he was led to analyze constructions of knowledge in the style of epistemic logic.

Fecal microbiota transplantation has demonstrated efficacy and is increasingly being used in the treatment of patients with recurrent Clostridium difficile infection. Despite a lack of high-quality trials to provide more information on the long-term effects of FMT, there has been great enthusiasm about the potential for expanding its applications. However, FMT presents many serious ethical and social challenges that must be addressed as part of a successful regulatory policy response. In this article, we draw on a sample of the scientific (...) and bioethics literatures to examine clusters of ethical and social issues arising in five main areas: informed consent and the vulnerability of patients; determining what a “suitable healthy donor” is; safety and risk; commercialization and potential exploitation of vulnerable patients; and public health implications. We find that these issues are complex and worthy of careful consideration by health care professionals. Desperation of a patient should not be the basis for selecting treatment with FMT, and the patient's interests should always be of paramount concern. Authorities must prioritize development of appropriate and effective regulation of FMT to safeguard patients and donors, promote further research into safety and efficacy, and avoid abuse of the treatment.

Greenwashing has become a common way in which many enterprises address expectations related to corporate social responsibility. As an abnormal and fake type of social responsibility behavior, greenwashing causes many problems, thus highlighting the importance of exploring the impact of corporate greenwashing. However, previous studies have mainly examined the impacts of greenwashing on enterprises, industry, and society, and the impact of greenwashing on individual employee behavior, which is important with regard to the sustainability of the enterprise, remains limited. The main (...) purpose of this study is to explore how perceived greenwashing affects employee green behavior (EGB). Based on the stimulus–organism–response theory and social cognitive theory, a two-wave survey was conducted to investigate 232 Chinese enterprise employees. The impact of perceived greenwashing on EGB was analyzed. The mediating role of green organizational identity (GOI) and the moderating role of self-serving leadership in this context were examined. The results reveal that perceived greenwashing is negatively related to EGB. Furthermore, GOI mediates the direct relationship between perceived greenwashing and EGB. Self-serving leadership weakens the positive relationship between GOI and EGB. This study thus develops a theoretical model of greenwashing and EGB. It also provides empirical evidence that can support attempts to promote EGB. (shrink)

Fecal microbiota transplantation is reportedly the most effective therapy for relapsing Clostridium Difficile infection and a potential therapeutic option for many diseases. It also poses important ethical concerns. This study is an attempt to assess clinicians’ perception and attitudes towards ethical and social challenges raised by fecal microbiota transplantation. A questionnaire was developed which consisted of 20 items: four items covered general aspects, nine were about ethical aspects such as informed consent and privacy issues, four concerned social and regulatory issues, (...) and three were about an FMT bank. This was distributed to participants at the Second China gastroenterology and FMT conference in May 2015. Basic descriptive statistical analyses and simple comparative statistical tests were performed. Nearly three quarters of the 100 respondents were gastro-enterologist physicians. 89% of all respondents believed FMT is a promising treatment modality for some diseases and 88% of whom chose clinical efficacy as the primary reason for recommending FMT. High expectation from patients and pressure on clinicians was reported as the most frequent reasons for not recommending FMT. The clinicians who had less familiarity with FMT reported significantly more worry related to the dignity and psychological impact of FMT compared to those who have high familiarity with FMT.More than half of the respondents were concerned about the commercialization of FMT, although almost one in five respondents did not see this as a problem. We found most respondents have positive attitudes towards FMT but low awareness of published evidence. Informed consent for vulnerable patients, privacy and protection of donors were perceived as the most challenging ethical aspects of FMT. This study identified areas of limited knowledge and ways of addressing ethical issues and indicates the need to devise the education and training for clinicians on FMT. (shrink)

In this study, we propose and test the relationship between CSR and firm financial performance, how this relationship differs between firms led by CEOs with political connections and those led by CEOs without political connections, and how this relationship differs between state-owned firms and nonstate-owned firms. Based on a sample of 1645 Chinese listed firms during the period 2011 and 2020 (inclusive), we find that CSR has an inverted U-shaped relationship with firm financial performance. As the level of CSR increases (...) from slight to moderate, CSR is positively related to firm performance; as the level of CSR increases from moderate to great, CSR is negatively related to firm financial performance. Additionally, we find that this inverted U-shaped relationship differs between firms led by CEOs with political connections and those led by CEOs without political connections and differs between state-owned firms and nonstate-owned firms. That is, both the synergic effect (positive effect) of CSR on firm financial performance when the level of CSR is low and the competitive effect (negative effect) of CSR on firm financial performance when the CSR is high are more pronounced for firms led by CEOs without political connections and nonstate-owned firms than for firms led by CEOs with political connections and state-owned firms. The theoretical and managerial implications of these findings are discussed. (shrink)

Resumen: La esencia del desarrollo del ecoturismo moderno reside en la coexistencia armónica y armoniosa de la relación entre el hombre y la naturaleza, que es la práctica ecológica del turismo bajo el trasfondo del desarrollo sostenible moderno. El desarrollo del turismo tradicional se centra en los intereses económicos y descuida la protección sostenible de la ecología turística, y el ecoturismo se ha convertido gradualmente en la dirección de desarrollo y reforma del turismo contemporáneo. El taoísmo hace hincapié en seguir (...) a la naturaleza, lo que tiene evidentes tendencias naturalistas, proporciona diferentes perspectivas filosóficas clásicas tradicionales para comprender la relación entre la naturaleza y el desarrollo humano, y tiene un importante significado esclarecedor para promover el desarrollo común del hombre y la naturaleza. El taoísmo aboga por respetar e imitar las leyes del desarrollo natural, persiguiendo la armonía general entre el hombre y la naturaleza, y es coherente con la naturaleza intrínseca del ecoturismo moderno. Por lo tanto, basándose en el pensamiento ecológico taoísta, la investigación explora la vía de desarrollo de la cultura ecoturística sostenible contemporánea y proporciona orientación teórica para el desarrollo armonioso y la unidad del hombre y la naturaleza.

Quasi-Boolean modal algebras are quasi-Boolean algebras with a modal operator satisfying the interaction axiom. Sequential quasi-Boolean modal logics and the relational semantics are introduced. Kripke-completeness for some quasi-Boolean modal logics is shown by the canonical model method. We show that every descriptive persistent quasi-Boolean modal logic is canonical. The finite model property of some quasi-Boolean modal logics is proved. A cut-free Gentzen sequent calculus for the minimal quasi-Boolean logic is developed and we show that it has the Craig interpolation property.

In this paper I have two main aims. My first aim is to introduce the notion of bounded emotionality. This notion is the analogue of that of bounded rationality in behavioural economics. Bounded rationality says, roughly, that human beings are cognitively limited with respect to their processing and memory capacities. Bounded emotionality says that we are limited in our emotional capabilities, notably in the intensity, duration, and possible combinations of our emotional states. Bounded rationality is a foundational notion in behavioural (...) economics and has played an important role in various fields of philosophy as well. In particular, in epistemology bounded rationality has been thought to have implications with respect to our doxastic norms. My second aim in this paper is to suggest that bounded emotionality also has an important role to play in philosophy. As a case in point, I discuss the implications that bounded emotionality has for our doxastic norms. In particular, I argue that one is not obligated to believe something or to stop holding a belief if one could not believe/fail to believe it without having an emotional response that exceeds one's bounded emotional capacities.

Los discursos públicos que circulan sobre las matemáticas y su aprendizaje determinan el modo en que las familias y los alumnos dan sentido a sus experiencias escolares. En Estados Unidos, estos discursos pueden desempeñar un papel importante en el desarrollo de la política educativa pública debido al compromiso de los consejos escolares públicos de escuchar las voces de la comunidad, así como al reciente (aunque no nuevo) aumento de la organización de grupos de padres conservadores bien financiados que trabajan para (...) mantener -y exacerbar- la desigualdad de oportunidades educativas que persiste en este país. En este trabajo analizamos el discurso público en torno al aprendizaje de las matemáticas en una reunión del consejo escolar local de la ciudad de Nueva York. Utilizando herramientas de análisis de la interacción, examinamos el discurso en torno a una propuesta para restablecer la selección basada en exámenes para la admisión en la escuela secundaria. Delineamos dos características clave de los supuestos de "sentido común" en torno al aprendizaje de las matemáticas que circularon en esta reunión -los estudiantes de matemáticas permanecen en una trayectoria de aprendizaje unidimensional, y con diferentes tasas de avance- e investigamos cómo estos supuestos jugaron en la construcción de un mundo figurado de "matemáticas escolarizadas". Argumentamos que las consecuencias que se derivan necesariamente de estos supuestos de sentido común construyen las matemáticas como jerárquicas y fijas, situando a los alumnos en una trayectoria de aprendizaje unidimensional. Por último, situamos este conjunto de supuestos emergentes en el proyecto racial neoliberal y consideramos las formas en que configuran una imaginación particular de la escolarización y las matemáticas bajo el neoliberalismo.

Customer civility is an established construct in the study of ethical consumption. However, scholars have paid insufficient attention to customer civility in relation to the flourishing peer-to-peer economy. Therefore, the purpose of this article is to develop and test a theoretical framework which examines the antecedents of the customer civility in the P2P economy. We use social exchange theory to develop a model that posits customer interaction experiences with property owners, properties, and P2P platforms as antecedents of customer civility in (...) the P2P economy. Two studies were used to test our framework: Study 1 comprises a survey of Chinese customers ; Study 2 involves secondary data crawled from the Web site of Xiaozhu, one of China’s largest P2P accommodation platforms. OLS regression analysis was used for hypothesis testing. Results demonstrate three antecedents of customer civility in the P2P accommodation sector: interpersonal trust, property experience, and platform governance. In addition, the positive effect of interpersonal trust on customer civility is stronger when customers have high economic incentive, while the effect of property experience is significantly stronger when customers have low economic incentive.

Based on the expanded theory of planned behavior, this study first explores the configuration relationship between founder management and innovation by using the fuzzy-set qualitative comparative analysis. Based on the theory of planned behavior, this study divides the behavior intention of founders into three categories: Attitude, subjective norm, and perceived behavior control. Using fsQCA, we found that there are two ways to achieve high innovation input of enterprises. In combination with the two ways, the factors such as male and highly (...) educated founder, and large firm size can effectively increase the innovation input of firms, which is consistent with the three aspects of the behavioral intention of the theory of planned behavior, and it proves that the theory of planned behavior can effectively explain the configuration relation between the founder and firm innovation. In addition, this study finds that the innovation output is different from the innovation input, is dependent on the innovation ability of the firm itself, and is less influenced by the external environment.

ABSTRACTConsulting Heidegger's other texts composed during 1936–1942, this article employs a principle of charity and constructs a consistent discourse about an inceptual negativity Heidegger articulates through a confrontation with Hegel in GA 68. Heidegger deliberately differentiates his use of denial that bears Being-historical significance from Hegel's Negation that allegedly aims at synthesis or elevation as a dialectical movement. Being unsatisfied with his approach that remains entangled with metaphysics in the Contributions, Heidegger attempts to transform the question of the Nothing from (...) a subsidiary question to Beyng to an abyssal question. One needs to go under toward the Nothing in its concealed, conjoined, and most intimate relation to Beyng. The movement of going under is fundamentally significant for transitions that could occur from out of the history of Beyng. Never being the fullness of essence, the Nothing places a limit on Beyng, constantly thwarts its unfolding, and maint... (shrink)
