This study investigates how the ethnic visibility of Taiwan Hakka is improved through language use. The usage of a unique Hakka symbolic code <nganggiang stiff neck> is focused on. Based on data from the four Taiwan major newspapers, an analysis with text techniques shows that the code emerges along with social-political developments in Taiwan, with its meaning turning from negative to positive connotation. Its frequency is highly correlated with major political events in Taiwan, with peaks during the two or three years before presidential elections. It illustrates semiotic innovation, extending from Hakka to Hakka non-human, to non-Hakka, and to non-Hakka non-human frames. The salient image it creates increases Hakka ethnic visibility and enhances their ethnic identity. A significant implication is that minority ethnic groups can employ a unique symbolic code, empowering it with positive connotation. Through extensive language use, its representation can raise their ethnic visibility and enhance their ethnic identity. 相似文献

The cutwidth problem for a graph G is to embed G into a path such that the maximum number of overlap edges (i.e., the congestion) is minimized. The investigations of critical graphs and their structures are meaningful in the study of a graph-theoretic parameters. We study the structures of k-cutwidth \((k>1)\) critical trees, and use them to characterize the set of all 4-cutwidth critical trees. 相似文献

Consumer on-line behaviors are more important than ever due to highly growth of on-line shopping. The purposes of this study were to design placement methods of background music for shopping website and examine the effect on browsers' emotional and cognitive response. Three placement points of background music during the browsing, i.e. 2 min., 4 min., and 6 min. from the start of browsing were considered for entry points. Both browsing without music (no music) and browsing with constant music volume (full music) were treated as control groups. Participants' emotional state, approach-avoidance behavior intention, and action to adjust music volume were collected. Results showed that participants had a higher level of pleasure, arousal and approach behavior intention for the three placement points than for no music and full music. Most of the participants for full music (5/6) adjusted the background music. Only 16.7% (3/18) participants for other levels turn off the background music. The results indicate that playing background music after the start of browsing is benefit for on-line shopping atmosphere. It is inappropriate to place background music at the start of browsing shopping website. The marketer must manipulated placement methods of background music for a web store carefully. 相似文献

寻求哲学合理的存在方式,是今天困扰人们的重大课题之一。在此问题上,最为根本的是如何理解哲学与生活的真实关系,即回答哲学究竟应成为人的幸福生活的"主人"还是"仆人"。在哲学史上,以传统形而上学为代表的哲学形态长期以来把成为人"幸福生活的主宰"作为哲学的使命,其结果导致了人的思想和生活的抽象化。这是哲学陷入深层困境、人的思想和生活陷入深重灾难的重要根源。抛弃和摆脱成为人"幸福生活的主人"的欲望,甘心成为"幸福生活的仆人",这是哲学的重大觉醒,也是兑现它为人类服务诺言的基本前提。 相似文献

Effective recruitment is a prerequisite for successful execution of a clinical trial. ALLHAT, a large hypertension treatment trial (N = 42,418), provided an opportunity to evaluate adaptive modeling of recruitment processes using conditional moving linear regression. Our statistical modeling of recruitment, comparing Brownian and fractional Brownian motion, indicates that fractional Brownian motion combined with moving linear regression is better than classic Brownian motion in terms of higher conditional probability of achieving a global recruitment goal in 4-week ahead projections. Further research is needed to evaluate how recruitment modeling can assist clinical trialists in planning and executing clinical trials. 相似文献

The outbreak of a highly communicable disease, SARS, in Asia in 2003 has revealed the health risk of living in a high-density environment. To show the important connection between human health and environmental quality, this study surveys the prevalence of sick building syndrome (SBS) among apartment residents and their evaluation of indoor environmental quality (IEQ). Based on a sample of 748 households living in Hong Kong, two interesting findings are revealed: (1) nasal discomfort was the commonest home-related SBS symptom despite the absence of any central ventilation system in apartment buildings; (2) noise, rather than ventilation, was the major IEQ problem perceived by residents. Our statistical analysis further showed that residents with SBS symptoms were less satisfied with their IEQ than those without. That is, despite a positive evaluation of specific IEQ criteria with respect to the building residents lived in, if they reported feeling SBS related symptoms, the overall IEQ evaluation of their building could still be negative. This perception bias gives rise to a sample selection problem in measuring perceived IEQ, which has implications on housing management practices and the formulation of a healthy housing policy. 相似文献

A generalized negative binomial distribution is derived from the Markov Bernoulli sequence of successes and failures. We study the properties and applications of this distribution. The properties are illustrated by two examples of discrete time queueing systems. The distribution is then fitted to two data sets, the eruption record of Mt. Sangay, and a record of computer disk failure accesses. In the first case there is a strong serial dependence in the data and the generalized negative binomial provides a good fit, while in the second case, although there is a significant serial dependence, it is insufficient to justify the additional parameter of the distribution. We conclude by demonstrating the usefulness of the distribution in the field of statistical quality control. 相似文献

Study of a Markov model for a high-quality dependent process 总被引:1,自引:0,他引:1
For high-quality processes, non-conforming items are seldom observed and the traditional p (or np) charts are not suitable for monitoring the state of the process. A type of chart based on the count of cumulative conforming items has recently been introduced and it is especially useful for automatically collected one-at-a-time data. However, in such a case, it is common that the process characteristics become dependent as items produced one after another are inspected. In this paper, we study the problem of process monitoring when the process is of high quality and measurement values possess a certain serial dependence. The problem of assuming independence is examined and a Markov model for this type of process is studied, upon which suitable control procedures can be developed. 相似文献
