Abstract This study investigated how bilinguals’ perception of their first language (L1) differs according to age of reduced contact with L1 after immersion in a second language (L2). Twenty‐one L1 Korean‐L2 English bilinguals in the United States, ranging in age of reduced contact from 3 to 15 years, and 17 control participants in Korea were tested perceptually on three L1 contrasts differing in similarity to L2 contrasts. Compared to control participants, bilinguals were less accurate on L1‐sp

Research has shown that L1 speakers can routinely generate mental imagery corresponding to sentence meaning in reading comprehension. This may reflect an efficient process of semantic integration in which information from the input combines with an individual's linguistic and real world knowledge to form a semantic representation of a sentence. Semantic integration in L2 reading has received limited attention. The present study attempted to examine the activation of mental imagery in reading amo

Post-9/11 literature has been noted as lacking in critical force because it fails to envision America mediated by global history and international politics. The post-9/11 narratives of Don DeLillo and David Foster Wallace, however, attempt to move away from American insularity and attain worldliness, specifically by abandoning the influence of postmodernism, which seemed to reinforce the provincial, self-involved nature of American culture by fostering the ideas of indeterminacy, irony, and dept

Abstract Post-humanism accuses humanism of inventing a human subject who is domineering and destructive. As a remedy, it redefines the human as a being informed by passivity and finitude and bound by ontological vulnerability. In so doing, it undermines the creative and transformative power of human agency and obliterates politics and history as shaped by human actions. Noting how this intensifies the experience of alienation and de-humanisation, the essay looks to Marxist and socialist humanism

최근 고령화는 사회·경제적 시스템의 지속발전 가능성을 불안하게 하는 위험요인으로 작용하고 있다. 본 연구는 이론적 논란이 되고 있는 고령화와 노동생산성 간 관계를 실증적 연구 관점에서 평가하기 위하여, 한국의 분기별 자료와 성장회계접근방법 및 생산함수를 이용한 계량경제학적 모형으로 실증분석을 시도하였다. 실증적 분석 결과, 전체 노동자 중 55세 이상 노동자들이 1% 증가하면 1인당 노동생산성 증가율은 약 0.3%p 하락하는 것으로 추정되었다. 이러한 추정결과를 바탕으로 한국의 미래 노동생산성을 전망한 결과, 노동력의 고령화는 베이비붐 세대가 고령 노동자의 주요 그룹이 되는 2015년 – 2016년에 노동생산성을 상당히 감소시킬 것으로 예측된다. 본 연구는 노동력의 고령화는 한국경제 생산성을 저하시키는 요인으로 작용하기 때문에 고령화의 부정적인 영향을 상쇄하고 경제전반으로 양(+)의 생산성 증가를 유발하기 위해서는 여타 부문에서 생산성 향상을 위한 상당한 노력과 정책이 필요함을 시사

본 연구는 평가의 설계 및 개발 단계에서부터 인지진단이론에 의해 제작된 컴퓨터화 형성평가 도구가 실제 중학생들의 수학 성취도와 수학에 대한 정의적 특성에 어떠한 영향을 미치는지 확인하고 그에 따른 시사점을 제공하고자 하는 목적을 가진다. 성태제(2018)가 개발한 인지진단이론에 의한 형성평가 도구를 활용하였으며, 지필검사와 피드백이 없는 집단, 지필검사와 지연된 피드백을 준 집단, 컴퓨터화 검사와 즉각적 피드백을 준 집단으로 나누어 수학 성취도와 수학에 대한 정의적 특성을 분석하였다. 분석 결과, 지필검사 실시 집단은 사전과 사후검사 점수 차이가 통계적으로 유의하지 않았던 반면 컴퓨터화 검사 실시 집단은 총점, 덧셈, 뺄셈, 곱셈, 나눗셈 점수가 사후검사에서 통계적으로 유의하게 증가하였다. 공분산분석 결과 총점과 뺄셈 점수에서 집단간 유의한 차이가 나타났으며, 컴퓨터화 검사 집단과 지필검사 두 집단의 복합 대비가 통계적으로 유의하였고 실질적인 점수 차이 또한 나타났다. 수학에 대한

Ever since the publication of Philip Roth’s American Pastoral, critics have debated whether the text’s unfavorable and reductive depiction of the radicals in the long 1960s can be attributed to Roth’s own conservatism. The debate has been in part further aroused by his supposedly more sympathetic account of the fall of the protagonist “the Swede,” who embraces all things considered as standing for America itself. However, by drawing on various historical contexts and materials ―the history of th

In Disgrace, J. M. Coetzee scrutinizes what it might mean, in post-apartheid South Africa still fraught with racial and political animosity, to tell the story of a disgraced man learning to relate to animals with compassion and humility. The novel highlights the urgency of this animal ethics in that it mitigates the cruelty of utilitarian logic that reduces all living beings to the status of disposable things. In addition, it interrogates the ways in which speciesism operates hand-in-hand with r

In Amitav Ghosh’s The Hungry Tide (2004) are the stories of humans and animals, who suffer the consequences of British colonialism, state violence, and even well-intentioned conservationist movements. Especially prominent is the story of the indigenous population of humans and tigers in the islands of the Sundarbans, whose well-being is pit against one another so that justice for humans leads to a neglect of tigers, and likewise, justice for tigers leads to a dismissal of humans. Against this di

This dissertation explores advanced Bayesian inference methods for analyzing longitudinal binary and ordinal data, with a focus on multivariate probit models. In medical and survey research, responses often follow an ordinal structure, presenting unique challenges due to their discrete, ordered nature. Traditional statistical methods, including Generalized Linear Mixed Models (GLMMs), Generalized Estimating Equations (GEE), and joint maximum likelihood estimation model, partially address these c
