恒带宽窄带集总跳频滤波器的理论计算与实现

为了快速准确地设计并制作恒带宽窄带集总跳频滤波器,提出了一种随频率变化而 变化的负载结构。通过对这种结构模型的分析,得到了其关于频率和相对带宽的精确变换公 式,利用麦夸特优化法对其进行优化计算,快速得到该负载结构各部件的最优值。最后利用 该方法设计并制作了一个二阶集总带通滤波器。实验结果表明,该方法实现滤波器比传统 手调快几倍,该滤波器在跳频范围30～90 MHz内保持相对恒带宽598%～689%,回波 损耗小于-19 dB,插损大于-2.2 dB。

An empirical study of evaluating supply chain management integration using the balanced scorecard in Taiwan

Supply chain management (SCM) is essential for strengthening competitiveness, customer satisfaction, management performance, and achieving continued success. The development of effective measures of SCM performance is crucial to companies. Most corporations place considerable importance on SCM and the concept of balanced scorecard (BSC). Most studies, however, typically discuss SCM and BSC independently without examining their relationship. This study attempts to integrate SCM and BSC based on a thorough discussion of BSC measures in Kaplan and Norton. The main objectives of this study are to evaluate SCM performance using the BSC to thereby assess the business performance of many of Taiwan's industries that have implemented SCM. This study initially utilizes case studies; a research model and hypotheses are modified according to the case study findings. A questionnaire-based survey forms the second phase of data collection and data analysis. The research framework is analyzed and validated. Case study findings indicate that companies use varying degrees of SCM integration. Data analysis supports a positive correlation between SCM integration and BSC and a direct correlation between SCM integration and each BSC dimension.     

Corporate social responsibility,credit rating,and private debt contracting: new evidence from syndicated loan market

We examine the impact of corporate social responsibility (CSR) activities on loan spreads of syndicated bank loans, with a particular interest in how CSR and credit ratings are interrelated as a joint determinant of loan spreads. Focusing on private debt contracts, we show that both CSR strengths and concerns are related to their loan spreads. CSR strengths work to lower firm risk, hence reducing the loan spread, whereas CSR concerns increase firm risk, thus increasing the loan spread. Once we include detailed credit rating information in the models, however, CSR concerns lose significance, but CSR strengths remain significantly related to the loan spread. We also find that both CSR strengths and CSR concerns are related to loan spread for non-rated firms, but the CSR concern effect is stronger than the CSR strength effect for these firms. A further test shows that firm risk measured by stock return volatility plays as a direct channel through which a firm’s CSR activities affect loan spreads, whose result lends further support to our main results. Overall, our results provide strong evidence that CSR matters to the pricing of loan contracts beyond credit rating information and the results remain robust to the possible firm size effect and the endogeneity issues.

Dependency,Globalization and Overseas Sex‐related Consumption by East Asians

Previous research has used dependency theory to explain sex consumption by rich, northern men travelling to ‘developing countries’. Little is known about how this perspective can be applied to sex‐related consumption by tourists from non‐western regions. Analyzing the East Asian Social Survey of 2008, we found that many eastern Asians had engaged in sex‐related entertainments abroad. People from the newly rich countries had become exploiters of sexual services in peripheral countries. East Asian tourists also went west and north bound overseas for sexual pleasures. We argue that the increasing economic activities and travelling opportunities across borders may better explain the overseas sex‐related consumption of eastern Asians than dependency theory.

论高校人性化教育的实施策略

人性化教育是以人为本的教育。应把以人为本的教育理念渗透到学校领导的办学思想、管理人员的管理观念、教师的教书育人以及学生本身的思想觉悟之中。实施人性化教育应处理好尊重个性与放任自流、人的发展与知识学习、人文文化与科学文化等之间的关系,使大学生在厚重的人文关怀中健康成长。     

The loyalty process of residents and tourists in the festival context

Few attempts have been made to find out if the loyalty process for residents and tourists in the context of cultural festivals is the same. This study investigated the influence of involvement on satisfaction as factors contributing to the likelihood of returning to an annual festival for residents and tourists. A sample of 412 attendees of a cultural and historic festival in the Midwest region of the USA was surveyed. The results showed that both residents and tourists who were more involved with the festival had higher satisfaction levels. However, only residents who were highly satisfied with the festival were more likely to attend again, whereas tourists' satisfaction level did not significantly influence their likelihood of returning. For tourists, it is likely that their quest for novelty is influential in shaping their future intentions. Implications of this result for the sustainability of cultural festivals are discussed.
