<P>For the first time, the homogeneous adsorption of a green inhibitor on the surface of steel was evidenced using energy dispersive X-ray spectral elemental mapping. Inhibition of steel corrosion in 1.0 M hydrochloric acid by Tabernaemontana divaricata plant extract and the evidences for adsorption of the inhibitor are described in this study. The inhibition characteristics of the green inhibitor were evaluated by means of weight loss and electrochemical measurements. A maximum of 95% inhibition efficiency was achieved by using 500 ppm of inhibitor. The adsorption of green inhibitor was found to obey the Langmuir's isotherm model. Further, the energy dispersive spectral mapping revealed the homogeneous distribution of the nitrogen, which indicated for the presence of inhibitor on the steel surface. (C) 2015 Elsevier B.V.

Four castrated Corriedale sheep were used in an experiment to observe the changes in insulin, growth hormone and cortisol in blood plasma following a prolonged infusion of a high rate of somatostatin (SRIF). The animals wee infused with either saline, 25 or $50{\mu}g/kg/h$ of SRIF for 3 hours. Blood samples wee taken every 20 minutes until 1 hour following the end of the SRIF infusion. Both SRIF infusion levels suppressed the release of insulin into plasma to approximately 3.5 mU/l. The SRIF infusions reduced the concentration of growth hormone to barely detectable levels. Following the withdrawal of SRIF there was a massive release of growth hormone. The plasma concentration of growth hormone reached 60 ng/ml within 20 minutes, the length of the growth hormone discharge was in excess of 1 hour. The extent of the discharge of growth hormone following the SRIF infusions was greater than that suppressed by the infusion. The SRIF apparently caused an increase in the plasma concentration of cortisol at the end of the infusion and following is withdrawal. This is possibly associated with some change in the metabolic rate associated with the suppression of insulin or glucagons release. The present experiment demonstrates that a high rate of SRIF infusion can not completely inhibit the release of insulin into the plasma.

This study used a cross-sectional survey design to examine the moderating role of psychological capital (PsyCap) on the association between psychological distress (depression, anxiety, and stress) and well-being among 387 college students in India. PsyCap refers to an individual’s positive psychological state of development that is comprised of hope, efficacy, resilience, and optimism. There was a negative association between psychological distress and well-being, whereas a positive association was found between PsyCap and well-being. As hypothesized, PsyCap moderated the association between psychological distress and well-being. The PsyCap components of hope, efficacy, resilience, and optimism each acted as a moderator in the association between psychological distress and well-being. The practical implications of enhancing PsyCap to positively affect well-being and reduce psychological distress in college students are provided through the lens of positive psychology.

Studies on the influence of the home environment on literacy acquisition of a sequential or heritage language (L2) are scarce, although a body of research has documented that a family literacy environment plays a significant role in children’s linguistic development of a native or dominant language (L1). This study examined the role of the home literacy environment, including home language use, parental language skills, literacy practices, and demographic characteristics, in L2 literacy acquisition. Fifty Korean-American children who spoke English as their dominant language (L1) and learned to read Korean as a sequential heritage language (L2) participated in the study. Results showed that a mothers’ educational level, the number of books at home, the frequency of private lessons in extracurricular activities, and L2 Korean use at home predicted L2 Korean letter and word identification skills, orthographic awareness, and nonword reading. When a mothers’ educational level was taken into account, the effects of book availability at home, the frequency of tutoring, and L2 use at home on L2 Korean reading outcomes significantly diminished; book availability at home and L2 use at home explained a unique variance in L2 word identification skills, book availability at home in L2 orthographic awareness, and the frequency of tutoring in L2 Korean nonword reading. Despite the discontinuity of languages used at home and in school, commonalities seem to exist in the impact of the home literacy environment on children’s L1 and L2 literacy development.

This study examined relationships among metacognitive skills, including inference, summarizing skills, fluency and memory, listening, and academic reading in English as a foreign language (FL). As a secondary analysis of the field test of the Pearson Test of English Academic, a total of 585 nonnative speakers’ academic language and reading skills were analyzed using confirmatory factor analysis. One-factor and four-factor models were tested using 12 observed variables and four latent constructs for structural equation modeling to establish a model of reading in English as an FL. The model of reading was tenable for nonnative speakers’ skills in English for academic purposes. Consistent with previous findings, listening skills were found to be important for reading skills. Other metacognitive skills, such as inference, summarizing, and fluency and memory, were also robust predictors of efficient academic reading. Of the given variables, the most dominant variable in FL reading for academic purposes was fluency and memory.
The Causes of Trade Tensions and their Consequences for Financial Stability

I have two objectives in this short paper. First, I explore some of the reasons why the world is currently experiencing so much tension associated with international trade. Second, I discuss some of the consequences of this trade tension for financial stability.
가정 문해 활동이 어린이 학습자 의 계승어로서 한국어 읽기 능력에 미치는 영향

가정 문해 환경이 모국어 발달에 중요한 역할을 한다는 연구결과는 오랫동안 축적 되어 왔으나, 가정 문해 환경이 제2언어나 계승어(이후 제2언어로 통칭) 읽기 발달에 끼치는 영향에 대한 연구는 그리 많지 않다. 이에 본 연구는 가정 내 언어 사용 정도, 부모의 언어 능력, 가정 문해 활동, 가정의 인구통계학적 특성 등을 포함한 전반적인 가정 문해 환경이 제2언어 읽기 능력에 미치는 영향을 살펴보았다. 연구에는 영어를 모국어로 하면서 계승어로서의 한국어를 배우기 시작한 한국계 미국인 아동(5세에서 8세 사이) 50명이 참가했다. 어린이들은 한국어 읽기 능력을 측정하는 실험에 참여하였고, 해당 아동의 부모는 가정 문 해 환경 설문 조사에 답변하였다. 실험 결과, 어머니의 교육 정도, 가정 내 장 서 수, 과외 활동의 개인 교습 횟수, 가정 내 한국어 사용 정도라는 4가지 요 소가 제2언어 학습 아동의 한글 자모와 단어 변별, 철자 식별, 무의미단어 읽 기 능력을 예측함을 발견했다. 그러나 어머니의 교육 정도가 통계적으로 통제 되었을 때에는, 가정 내 장서 수, 개인 교습 횟수, 가정 내 한국어 사용 정도가 아동의 한글 읽기 결과에 미치는 고유한 영향이 감소했다. 구체적으로 가정 내 장서 수와 한국어 사용 정도가 아동의 단어 변별 능력에, 장서 수가 어린이들 의 철자 식별 능력에, 개인 교습 횟수가 무의미단어 읽기에 고유한 변동량을 설명하였다. 본 연구는 가정 문해 환경 설문 조사와 아동의 읽기 실험 결과를 정량 분석한 방법으로 제2언어 아동 학습자의 한국어 읽기 발달에 대한 가정 문해 환경의 영향을 보여주었다는 점에서 의의를 찾을 수 있다.

Why Do Trade Negotiations Take So Long?
( Christ Oph Moser ),( Andrew K Rose ) 세종대학교 경제통합연구소 2012 Journal of Economic Integration Vol.27 No.2
The Doha multilateral round of trade negotiations sponsored by the WTO has been dragging on for over a decade, with no end in sight. In this short paper we assess empirically what determines the duration of trade negotiations, focusing on the span between the start of trade talks and their conclusion. We use data from 88 regional trade agreements between 1988 and 2009, and a semi-parametric Cox proportional hazards model. Four factors are robust determinants of the length of RTA negotiations. Negotiations are more protracted when there are more countries at the negotiation table, and when the countries are not from the same region. Negotiations between more open and richer countries also finish more quickly.
