This study explored the role of market-oriented public relations. The study involved two surveys; one explored the perspectives of business managers and another of the perspectives of public relations practitioners, and compared their views concerning market-oriented and non-market-oriented relations. While business managers and public relations practitioners of non-market-oriented relations valued the contribution of market-oriented public relations to organizational effectiveness in terms of revenue generation and cost reduction, practitioners of market-oriented public relations ascribed their contribution to organizational effectiveness in terms of media publicity and exposure. This paper concludes with a discussion of practical applications and theoretical implications.  相似文献

Abstract

The circumstances that led Frank Capra to view Leni Riefenstahl's notorious documentary of the 1934 Nuremberg rallies, Triumph of the Will, is well-known. What is less known is the extent to which the themes inherent in Capra's filmmaking through the 1930s, and Riefenstahl's own interest in ideas of national identity, social commentary and romanticism in her fictional and documentary films, mapped out a set of cinematic coincidences between the two little discussed in the body of literature devoted to these directors. This article lays out a number of those coincidences and, in the process, compares the theoretical strain of political romanticism that winds its way through Capra and Riefenstahl's work. The iconic and symbolic imagery in their films suggests interesting and important comparative aspects to their canon, but also that a fascination in political romanticism led them to differing conclusions about the impact and threat of media and propaganda forces lined up in alliance with totalitarian powers during the 1930s and '40s.  相似文献

Abstract

This article addresses the relationship between language and identity and language and power. Language is viewed as an important vehicle through which empowerment can occur in society and through which social workers can contribute to the empowerment of dual language individuals and communities. Language suppression is viewed through the framework of bilinguaphobia, a term coined by Faltis and Coulter in 2004. Because of the long and unique history of Spanish in Southwestern communities, the authors suggest that true empowerment must overcome the prevalent discourse of fear of bilingualism. This article suggests that the present status and identity of Latinos in the Southwestern United States would be enhanced and affirmed by the healthy co-existence of two tongues and two cultural frameworks and that social workers should recognize and advocate for the power of bilingual discourses.  相似文献

Abstract

This article reviews policies and services related to immigrants, refugees and asylum seekers in the U.S. Definitions of immigration categories are provided to clarify the context in which services operate. Particular attention is given to issues that are unique to populations of the Southwest. Historical information on this region is offered; immigration trends and recent statistics are presented. The article is based on published data; field interviews with personnel in selected immigrant and refugee serving social agencies are used to compliment the literature. The authors highlight the social consequences of the global phenomenon of migration, whether motivated by economic or political realities. Recommendations for those who serve immigrants, refugees and asylum seekers are offered.  相似文献

In this paper, the maximum likelihood (ML) and Bayes, by using Markov chain Monte Carlo (MCMC), methods are considered to estimate the parameters of three-parameter modified Weibull distribution (MWD(β, τ, λ)) based on a right censored sample of generalized order statistics (gos). Simulation experiments are conducted to demonstrate the efficiency of the proposed methods. Some comparisons are carried out between the ML and Bayes methods by computing the mean squared errors (MSEs), Akaike's information criteria (AIC) and Bayesian information criteria (BIC) of the estimates to illustrate the paper. Three real data sets from Weibull(α, β) distribution are introduced and analyzed using the MWD(β, τ, λ) and also using the Weibull(α, β) distribution. A comparison is carried out between the mentioned models based on the corresponding Kolmogorov–Smirnov (KS) test statistic, {AIC and BIC} to emphasize that the MWD(β, τ, λ) fits the data better than the other distribution. All parameters are estimated based on type-II censored sample, censored upper record values and progressively type-II censored sample which are generated from the real data sets.  相似文献

We display the first two moment functions of the Logitnormal(μ, σ2) family of distributions, conveniently described in terms of the Normal mean, μ, and the Normal signal-to-noise ratio, μ/σ, parameters that generate the family. Long neglected on account of the numerical integrations required to compute them, awareness of these moment functions should aid the sensible interpretation of logistic regression statistics and the specification of “diffuse” prior distributions in hierarchical models, which can be deceiving. We also use numerical integration to compare the correlation between bivariate Logitnormal variables with the correlation between the bivariate Normal variables from which they are transformed.  相似文献

The change from the z of “Student's” 1908 paper to the t of present day statistical theory and practice is traced and documented. It is shown that the change was brought about by the extension of “Student's” approach, by R.A. Fisher, to a broader class of problems, in response to a direct appeal from “Student” for a solution to one of these problems.  相似文献

Abstract

Finding and deciphering serials records in online catalogs is a challenge to many library users. To understand and analyze these challenges, the author conducted searches for scientific journal titles in the online catalogs of Committee on Institutional Cooperation (CIC) libraries. The first part of the study measures the difficulty of retrieving serial records from online catalogs comparing one-word versus multiple-word titles. The second part analyzes displays for complexity by measuring the length of the complete record and the length of the holdings statements. These data show the complexity of displays and indicate the potential confusion that these displays may induce in library users.  相似文献

We report on an empirical investigation of the modified rescaled adjusted range or R/S statistic that was proposed by Lo, 1991. Econometrica 59, 1279–1313, as a test for long-range dependence with good robustness properties under ‘extra’ short-range dependence. In contrast to the classical R/S statistic that uses the standard deviation S to normalize the rescaled range R, Lo's modified R/S-statistic Vq is normalized by a modified standard deviation Sq which takes into account the covariances of the first q lags, so as to discount the influence of the short-range dependence structure that might be present in the data. Depending on the value of the resulting test-statistic Vq, the null hypothesis of no long-range dependence is either rejected or accepted. By performing Monte-Carlo simulations with ‘truly’ long-range- and short-range dependent time series, we study the behavior of Vq, as a function of q, and uncover a number of serious drawbacks to using Lo's method in practice. For example, we show that as the truncation lag q increases, the test statistic Vq has a strong bias toward accepting the null hypothesis (i.e., no long-range dependence), even in ideal situations of ‘purely’ long-range dependent data.  相似文献

作为20世纪美国南方最著名的作家之一,对黑人生活的和种族问题的关注是福克纳小说中不可忽视的组成部分。他痛恨种族歧视,同情黑人的命运,并赞美黑人身上的优秀品质,但是在当遇到彻底解决南方奴隶制的问题时,福克纳无论在作品里还是言论中都表现出复杂而矛盾的态度。由于受到时代,社会,家庭和自身局限性的限制,在三部不同时期的作品中福克纳对于种族观点的变化可以清晰地体现出来。  相似文献
