普通的塑料遇到高温就会变形,可有一种塑料,它的强度很高,具备某些金属性能,有良好的机械性和尺寸稳定性,在高低温下其优良性能仍能保持。它就是工程上应用的—类高分子合成材料——工程塑料。目前,工程塑料主要包括聚酰胺(尼龙、PA)、聚碳酸酯(聚碳、PC)、聚甲醛(POM)、聚酯(主要 PBT)及聚苯醚(PPO)五种。它们能代替金属用于机器制造、仪器仪表工业、交通运输、建筑及尖端科技中的宇宙飞船部件。近几十年,世界工程塑料行业发展迅速,从70年代开始,工程塑料的增长率就超过普通塑料,年平均增长率达到15%,比普通塑料高—倍多。随着我国国民经济的不断发展,各种产业对工程塑料的需求不断扩大,可预见我国工程塑料市场将会呈现一派新的气象。  相似文献

We propose that Generation Y college students’ motivations to study abroad are rooted in the desire for individual growth, which, combined with other motivation factors—gender, parents’ educational level, prior international experience, age, and household income—drives the intent to study abroad. The study samples juniors and seniors in business majors, thereby attempting to shorten the temporal distance between study abroad intent and action. A significant number of students declare intent to study abroad as freshmen, yet fail to act on those intentions when the opportunity presents itself a year or two later. Results showed that the desire for individual growth was significantly and positively related to Gen Y business students’ intention to study abroad. Students’ prior experience visiting foreign countries and younger age positively moderated the effect of the desire for individual growth on intent to study abroad. The time lag between intent and action, and the fact that study abroad is a high involvement activity creates promotional challenges on how to best promote study abroad to Gen Y students. The article suggests practical implications and suggests how schools might increase study abroad participation among Gen Y college students.  相似文献

Despite a low rate of student participation in study abroad programs in the Caribbean, there is insufficient research about the individual factors that help determine business students’ willingness to study or to participate in internship programs abroad. This study aims to explore business students’ attitudes toward study abroad. The positive perceptions of students toward study or internship abroad raises questions about individual factors for business students’ outflow to study or participate in an internship abroad. This study also explores business students’ preferences for short- and long-term international study or internship abroad, as well as certification programs in international business. Moreover, it provides some insight into the segments of business students that are more likely to support these programs.  相似文献

Changes in ethnocentrism, intercultural communication apprehension, international awareness and activities were examined in business students participating in a 16-day consulting program abroad and compared to a control group of students at the home university. Anticipated changes in the study abroad students were found; however, when compared to the control group, the changes had little significance. Study abroad students had higher ethnocentrism, intercultural communication apprehension and lower intercultural awareness prior to going abroad; thus, the study abroad experience brought the STSA participants to the post-test levels of the control group. Implications for STSA programs and directions for future research are discussed.  相似文献

Increased activity by U.S. students to study abroad has invited several studies that have investigated the reasons for U.S. students to study abroad. Literature in the context of study abroad choices has been fragmented, with each study presenting an ad-hoc set of factors the author/s deem as important or that have been shown to be important in previous literature. However, no study to date has attempted to identify a theoretical framework that explains why these factors should be important in explaining the intention to participate in a study abroad program. In this study, we use the theoretical background of the Theory of Planned Behavior (TPB) and trait theory to unify the existing body of literature and arrive at a model that predicts study abroad intentions. We test this model by means of a survey administered in a U.S. university.  相似文献

The purpose of this study is to assess how studying abroad impacts the development of intercultural competence and the moderating role of student’s personality. This research uses a pre-post design with a sample of 264 undergraduate students from four Colombian universities; it includes a group of students who participated in a one semester study-abroad program and a control group who did not travel. The average level of increase in intercultural competence for the students who went abroad was 0.511 standard deviations above the average of those who had not studied abroad. The results from hierarchical linear regression did not yield any evidence that supports the moderating effects of the personality factors on the relation between study abroad and intercultural competence.  相似文献

Companies wish for universities to provide business students with international education and awareness. Short- and long-term study-abroad programs are an effective method by which this is accomplished, but relatively few American students study abroad. In response to these facts, this study develops hypotheses that predict student willingness to study abroad and tests the hypotheses using a survey of over 300 primarily business undergraduate students at a public Midwestern university. Results indicate a significant difference between student willingness to study abroad short-term versus long-term. Results also show that personal, situational, and location variables influence students' willingness to study abroad, though completing an international business class had no effect. Implications for international business scholars are discussed.  相似文献

随着贸易、投资自由化的蓬勃发展,我国上市企业对外投资越来越明显。本文采用以财务指标为基础的综合评价方法来衡量上市企业对外投资前后的业绩变动,并以此分析和检验了2002-2005年间我国上市企业对外投资的绩效。分析结果表明:我国上市企业对外投资绩效在整体上有一个先升后降的过程,尽管上市企业对外投资后第一年经营业绩会有一定的提升,但提升缺乏长期性;不同对外投资类型绩效不相一致,其中战略联盟对企业绩效有显著提升;民营控股上市企业的对外投资效果要优于国有控股的上市企业以及集体控股企业。  相似文献

This study furthers our understanding of how corruption affects the decision-making process of allocating foreign direct investment. Drawing on the responses of 28 managers in charge of establishing operations in a highly corrupt host country, we argue that those firms based in home countries with low levels of corruption are more proactive in preparing to face corruption abroad than those based in countries with high corruption levels. This means that firms from less corrupt home countries have strategies in place to deal with high corruption abroad. This finding is based on the fact that these firms have stronger pressures to not engage in corruption from their home stakeholders. Also, these firms might not have the experience of dealing with corruption at home, which hinders their potential to deal with corruption abroad. On the other hand, those firms based in highly corrupt home countries do not have clear strategies to deal with corruption abroad. This assertion is based on the fact that these firms might have familiarity in dealing with corruption and thus, might not see it as an obstacle to operating abroad.  相似文献
