The rank distribution of the maximin in a random matrix

Let S be a set of tm distinct real numbers and R a random t × m matrix of these tm numbers with rows {r_i} and columns (c_i}. Define b = Max Min x. l≤i≤t x?r_i. Let c be the event Max Min x = Min Max x. l≤i≤t x?r_i l≤i≤m x?c_i. This paper derives the probability distribution of the rank of b in S, as well as the same distribution conditional on c.     

Stationary bootstrapping for realized covariations of high frequency financial data

This paper studies the stationary bootstrap applicability for realized covariations of high frequency asynchronous financial data. The stationary bootstrap method, which is characterized by a block-bootstrap with random block length, is applied to estimate the integrated covariations. The bootstrap realized covariance, bootstrap realized regression coefficient and bootstrap realized correlation coefficient are proposed, and the validity of the stationary bootstrapping for them is established both for large sample and for finite sample. Consistencies of bootstrap distributions are established, which provide us valid stationary bootstrap confidence intervals. The bootstrap confidence intervals do not require a consistent estimator of a nuisance parameter arising from nonsynchronous unequally spaced sampling while those based on a normal asymptotic theory require a consistent estimator. A Monte-Carlo comparison reveals that the proposed stationary bootstrap confidence intervals have better coverage probabilities than those based on normal approximation.     

‘Miss mum’: mind and affective experience of Korean learners identified with autism spectrum and cognitive difficulties

Responding to the call for culturally informed research on autism spectrum (AS) to allow for the provision of appropriate services, this paper qualitatively explores the affective experience of five Korean learners identified with AS and cognitive difficulties by listening to their voices. The learners, supported by the use of visual aids and a choice of their preferred mode of communication, expressed the complexity of their inner experience that encompassed abilities as well as difficulties. The findings highlight the commonalities of experience between Korean and non-Korean individuals with AS, along with some aspects specific to the Korean cultural context.     

Making the familiar strange and making the strange familiar: understanding Korean children’s experiences of living with an autistic sibling

Based on the findings of a small‐scale study using visual ethnographic techniques with nine South Korean children, this article explores the role of culture in understanding autism. While autism is embedded within the ‘strange’ and ‘unfamiliar’, linked to exclusion and discrimination in Korean society, the children focussed on reframing their experiences of living with autism as ‘ordinary’. Despite the limitations of the small sample, the richness and depth of data generated by children themselves offers new insights into children’s interpretations and experiences of autism and raises interesting questions for cross cultural research in the field of disability.     

Enterprising? Disabled? The status and potential for disabled people’s microenterprise in South Korea

This article explores the position, potential and scope for self-employment and microenterprise for disabled South Koreans. The chronic barriers experienced in disabled people gaining paid work suggest that self-employment and enterprise might offer a good alternative to paid work. The self-determined nature of running a microenterprise has been shown to connect with disabled people who may not conform to standardised notions of body and brain that underpin many mainstream work contexts. Despite this promise, several barriers continue to beset disabled people’s access to micro-enterprise activity; barriers ranging from Confucian precepts, to employment protections that are geared largely towards paid employment and to the lack of training, finance and business support for disabled people starting up and sustaining microenterprise in Korea. The extension of legal protections, meaningful start-up subsidies, better business support and bridges between paid work and microenterprise are all seen as important policy correctives that would better support disabled people.

Unfinished modernity or another modernity? The South Korean case

South Korea has experienced “compressed capitalist development” over the last five decades, characterized by unprecedented levels of industrialization and democratization, with other distinctive features. This development experience causes some scholars to view the country as a site for a new modernity, following the Western prototype. Concerning the underlying nature of emerging modernity in South Korea, however, there have been controversial insights: some scholars argue that the country is now experiencing a Western type of modernity, and others refute this, saying that it has not at all been modernized. This paper investigates the dynamics and contradictions of capitalist development in South Korea from a perspective of vertical modernization. It considers the origins, process, and outcomes of modernization mainly in terms of democracy, economic growth, and welfare. We assume that there are “different sites and forms of modernity” in the world, and that South Korea would be a good candidate to examine for non-Western modernity. Yet it is our contention that the country’s modernity has been distorted and unbalanced in the development of society, culture, politics, and economy. Historically, South Korea has progressed through traditional unmodernity, colonial undermodernity, and Western modernity. A clear examination of the country’s development experience reveals to no small degree the complex nature of modernity, in that tradition, modernity, and postmodernity coexist in the present time. We conclude that South Korean modernity is an incomplete project still in progress.     

Culture‐Inclusive Theories of Self and Social Interaction: The Approach of Multiple Philosophical Paradigms

In view of the fact that culture‐inclusive psychology has been eluded or relatively ignored by mainstream psychology, the movement of indigenous psychology is destined to develop a new model of man that incorporates both causal psychology and intentional psychology as suggested by Vygotsky (1927). Following the principle of cultural psychology: “one mind, many mentalities” (Shweder et al., 1998), the Mandala Model of Self (Hwang, 2011a,b) and Face and Favor Model (Hwang, 1987, 2012) were constructed to represent the universal mechanisms of self and social interaction that can be applied to any culture; both models can be used as conceptual frameworks for analyzing mentalities of people in any given culture. Taking research works from Foundations of Chinese Psychology: Confucian Social Relation as exemplars (Hwang, 2012), this article illustrates how to construct culture‐inclusive theories of Confucianism by multiple philosophical paradigms. The mechanism of culture‐inclusive theory can be applied to explain qualitative research findings on lifeworld events of people in a particular society. It can also be utilized to predict results of quantitative research conducted to verify theoretical propositions in the scientific microworld by empirical methods.     

Understanding predictive information criteria for Bayesian models

We review the Akaike, deviance, and Watanabe-Akaike information criteria from a Bayesian perspective, where the goal is to estimate expected out-of-sample-prediction error using a bias-corrected adjustment of within-sample error. We focus on the choices involved in setting up these measures, and we compare them in three simple examples, one theoretical and two applied. The contribution of this paper is to put all these information criteria into a Bayesian predictive context and to better understand, through small examples, how these methods can apply in practice.     

A survey on nonadaptive group testing algorithms through the angle of decoding

Group testing, sometimes called pooling design, has been applied to a variety of problems such as blood testing, multiple access communication, coding theory, among others. Recently, screening experiments in molecular biology has become the most important application. In this paper, we review several models in this application by focusing on decoding, namely, giving a comparative study of how the problem is solved in each of these models.
