倾听儿童的声音：“儿童立场”幼儿园课程质量观的逻辑起点

满足儿童发展的需求是幼儿园课程最为基本的价值诉求。因此,“儿童立场”的幼儿园课程质量观应被重视。通过对哲学视域下质量话语权的转向、发展心理学视角下的儿童观基础以及儿童相关研究范式调整的梳理,不难发现,当前学术界关于儿童的研究已然将聚焦于儿童本身作为研究的基本遵循。由此,文章从理论层面论证了儿童在幼儿园课程质量中主体性地位的重要性,并从课程目标、课程内容、课程实施以及课程评价四个方面出发,论述了在教育实践场中“儿童立场”幼儿园课程质量观的基本样态。

An elastic-net penalized expectile regression with applications

To perform variable selection in expectile regression, we introduce the elastic-net penalty into expectile regression and propose an elastic-net penalized expectile regression (ER-EN) model. We then adopt the semismooth Newton coordinate descent (SNCD) algorithm to solve the proposed ER-EN model in high-dimensional settings. The advantages of ER-EN model are illustrated via extensive Monte Carlo simulations. The numerical results show that the ER-EN model outperforms the elastic-net penalized least squares regression (LSR-EN), the elastic-net penalized Huber regression (HR-EN), the elastic-net penalized quantile regression (QR-EN) and conventional expectile regression (ER) in terms of variable selection and predictive ability, especially for asymmetric distributions. We also apply the ER-EN model to two real-world applications: relative location of CT slices on the axial axis and metabolism of tacrolimus (Tac) drug. Empirical results also demonstrate the superiority of the ER-EN model.     

Entrepreneurial Motivations and Capabilities of Migrant Entrepreneurs in Australia

This article presents findings on immigrant entrepreneurship in Australia. The relationship between the entrepreneurial start‐up motivation, co‐ethnic preferences and entrepreneurial capabilities of established immigrant businesses are explored. We analyse data collected with a self‐administered survey questionnaire from 157 immigrant entrepreneurs in Melbourne's suburbs. Our findings show that immigrant entrepreneurs who report a high level of individual achievement as their start‐up motivation also report high levels of entrepreneurial capabilities in terms of opportunity recognition, managerial innovativeness and proactiveness. Immigrant entrepreneurs who are highly influenced by co‐ethnic preferences on staff employment and customer targeting report higher opportunity recognition than those who have a co‐ethnic preference on suppliers. We provide important insights and explanations for these findings and their implications for Australian immigrant entrepreneurs and policymakers.     

THE INFORMATION TECHNOLOGY REVOLUTION AND THE UNSECURED CREDIT MARKET

The information technology (IT) revolution coincided with the transformation of the U.S. unsecured credit market. Households' borrowing increased rapidly and there was an even faster increase in bankruptcy filings. A risk of default model with asymmetric information and costly screening is introduced to study this period. When information costs are high, the design of contracts under private information prevents some households from borrowing with a risk of default. As information costs drop, households borrow more and bankruptcy filings increase. Quantitative exercises suggest that the IT revolution may have played an important role in the transformation of the unsecured credit market. (JEL E43, E44, G33)     

Neoliberal discourses and ethnonormative regime in post-recognition Peru: redefining hierarchies and identities

ABSTRACT

This article analyses the impact of ‘recognition’ of cultural and ethnic diversity in Peru. It proposes that the rise of a new global ‘ethnonormativity’ – a regime to define and administrate cultural and identity differences, to establish boundaries between those who ‘are’ ethnic and those who are not, and to set rights and duties derived from identities – has had meagre effects in Peru. While the past decades have witnessed the emergence of Latin American political actors who regard indigenousness as their basic political identity, there has been no ‘emergence of indigenous movements’ in Peru. The discourses that highlight the importance of diversity have gained terrain – unsettling, to a certain extent, the narratives of assimilation through ‘development’ and mestizaje – and the Peruvian state has officially embraced ‘recognition’, including it in its official rhetoric and creating institutions to design policies to guarantee the rights of the indigenous and Afroperuvian ‘peoples’ (itself a label part of the language of multiculturalism). The state has also crafted a definition of ‘indigenous peoples’ and introduced ethnic variables in censuses and official statistics, thus being active in the production and regulation of subjects. Some civil society actors have also incorporated ethnic labels into their rhetoric to adapt to the global turn to identity politics. Peru remains, however, a fertile terrain for neoliberal policies and discourses of a different kind. A discourse that exalts ‘emprendedurismo’ (entrepreneurship) and states that success depends entirely on personal effort has become a new common sense, obscuring the structural inequality that has historically affected indigenous and Afroperuvian people. Extractivism continues to damage the environment and the rights of indigenous people, while the expansion of agribusiness in the coastal valleys of Peru keeps people – regardless of their ‘ethnic’ self-identification – in poverty and without basic labour and social rights. The article suggests that the ambiguities of the ethnonormative regime in Peru may serve as a diversion from structural issues in a context of neoliberalism and may re-elaborate racial hierarchies, racism and the narratives of mestizaje it allegedly opposes.     

Participatory Art as a Social Practice of Commoning to Reinvent the Right to the City

The right to the city is a concept that helps rethink spatial–social dynamics, which has recently reinvigorated the field of organization studies. Following Lefebvre and considering the failure of both the market and the state, other scholars pinpoint the need to rethink social–spatial and geographical–historical relations. They do so by theorizing the city as a host for urban commons. Collective and non-commodified, these spatial–social experiences need to be constantly reproduced and preserved through commoning practices in the struggle against spatial injustice. A case study shows that a civil society organization (CSO) uses participatory art to (re)produce urban commons at the level of a local community and to redress partially spatial injustice. We theorize participatory art-making as a social practice of commoning, i.e., a process of organizing for the commons—collective art-based activities to serve a community—and of the common—to (re)produce a community while performing them. Such commoning practices are not only about sharing urban resources but also about using and experiencing differently urban spaces. By making participatory artworks in public spaces and co-designing street furniture with residents of poor areas, TDA helps to better cope with the tensions between residents and local authorities and between amateurs and professional artists. By negotiating the long-term implementation of these creative artworks in the public space with public authorities, TDA has fostered the empowerment of inhabitants as they have experienced citizens’ reappropriation of some public spaces in Marseille.     

A quadratic time exact algorithm for continuous connected 2-facility location problem in trees

This paper studies the continuous connected 2-facility location problem (CC2FLP) in trees. Let \(T = (V, E, c, d, \ell , \mu )\) be an undirected rooted tree, where each node \(v \in V\) has a weight \(d(v) \ge 0\) denoting the demand amount of v as well as a weight \(\ell (v) \ge 0\) denoting the cost of opening a facility at v, and each edge \(e \in E\) has a weight \(c(e) \ge 0\) denoting the cost on e and is associated with a function \(\mu (e,t) \ge 0\) denoting the cost of opening a facility at a point x(e, t) on e where t is a continuous variable on e. Given a subset \(\mathcal {D} \subseteq V\) of clients, and a subset \(\mathcal {F} \subseteq \mathcal {P}(T)\) of continuum points admitting facilities where \(\mathcal {P}(T)\) is the set of all the points on edges of T, when two facilities are installed at a pair of continuum points \(x_1\) and \(x_2\) in \(\mathcal {F}\), the total cost involved in CC2FLP includes three parts: the cost of opening two facilities at \(x_1\) and \(x_2\), K times the cost of connecting \(x_1\) and \(x_2\), and the cost of all the clients in \(\mathcal {D}\) connecting to some facility. The objective is to open two facilities at a pair of continuum points in \(\mathcal {F}\) to minimize the total cost, for a given input parameter \(K \ge 1\). This paper focuses on the case of \(\mathcal {D} = V\) and \(\mathcal {F} = \mathcal {P}(T)\). We first study the discrete version of CC2FLP, named the discrete connected 2-facility location problem (DC2FLP), where two facilities are restricted to the nodes of T, and devise a quadratic time edge-splitting algorithm for DC2FLP. Furthermore, we prove that CC2FLP is almost equivalent to DC2FLP in trees, and develop a quadratic time exact algorithm based on the edge-splitting algorithm. Finally, we adapt our algorithms to the general case of \(\mathcal {D} \subseteq V\) and \(\mathcal {F} \subseteq \mathcal {P}(T)\).
