This study conducted a quantitative content analysis to examine corporate Inclusivity, Diversity, Equity, and Accessibility (IDEA) communication (n = 1216) from 48 corporations on Facebook through the lens of dimensionality, stakeholders, drivers (legitimation), and level of investment. Findings indicated that most of the IDEA communication on Facebook focused on gender and racial/ethnicity diversity, employee, and community stakeholders. The IDEA communication was almost equally value- and performance-driven and reflected external promotion level of investment. External stakeholders engaged more with performance-driven and external promotion IDEA communication. The volume of IDEA posts reflected corporate internal diversity practice and was positively related with Glassdoor ratings of the corporation by African American, Middle Eastern, and LGBTQ+ employees. 相似文献

This study assessed the business-centered and CSR-centered diversity communication of five American corporations along with the ensuing responses on the microblogging platform Twitter, the present analysis contributes to the literature on online diversity communication and public relations. The results revealed that companies that had long-term consistency in approaching diversity as CSR received more agreeable responses than those that made swift changes in the aftermath of increased pressure from activist groups. In addition, companies that communicated to a greater degree about the impact of diversity on the bottom line engendered higher user agreement than those who discussed diversity primarily from a CSR perspective.The results shed light on the importance of message consistency throughout longer periods of time. 相似文献

This pilot study explored the under-representation of Hispanics/Latinos in the public relations profession by conducting focused interviews with Hispanic practitioners. The study found that public relations was not the Latinos’ initial career choice, identified three barriers to Hispanics entering the profession, elicited practical suggestions to attract more Hispanics, and also revealed opportunities for future scholarly research to address the under-representation of Hispanics in public relations. 相似文献

The 2008 spike in world grain prices is widely recognised to have had serious impacts on food security and poverty, but these high grain prices are commonly described as low in historical terms – an inconsistency resulting from the use of advanced‐ and global‐economy price indices in calculating real prices. This ignores the high share of food in poor people's expenditures and the indirect effects of income growth on expenditure patterns of rich consumers. Poor consumers have not experienced the same falls in real food prices and are more vulnerable to price shocks. Different price indices must be developed to take account of differences between consumer groups. 相似文献

International social work students in Australia have reported difficulties in finding quality placement opportunities and dealing with issues such as language and cultural barriers. While placement issues have been mostly investigated from a student perspective, this study explores the experiences and perspectives of placement educators towards supervising international social work students. It draws on an online survey of 83 placement educators working for an Australian university. The majority of placement educators reported that they supervised international students differently to domestic students. These differences were negatively framed as challenges involving students’ language competence, their understanding of cultural norms, and knowledge of Australian welfare systems. This framing implies that cultural and linguistic differences between international students and placement educators are viewed in terms of student deficiency rather than as a positive opportunity for mutual learning and professional development. 相似文献

This article discusses the use of contemporary film in social work education, including the theoretical rationale for the inclusion of film from the perspective of narrative and adult learning theory as well as the application of the case method to the use of film. The student viewpoint and perspective is provided through the results of an exploratory research study with 109 Baccalaureate social work students who completed a survey questionnaire following a classroom activity involving a contemporary film. Analysis of the quantitative data and qualitative comments indicates that students believe that film is a beneficial adjunct to textbook and lecture content. 相似文献

While body fat is the most accurate measure of obesity, its measurement requires special equipment that can be costly and time consuming to operate. Attention has thus typically focused on the easier to calculate body mass index (BMI). However, the ability of BMI to accurately identify obesity has been increasingly questioned. This paper focuses attention on whether more general body mass indices are appropriate measures of body fat. Using a data set of body fat, height, and weight measurements, general models are estimated which nest a wide variety of weight–height indices as special cases. In the absence of a race and gender categorisation, the conventional BMI was found to be the appropriate index with which to predict body fat. When such a categorisation was made, however, the BMI was never selected as the appropriate index. In general, predicted female body fat was some 10 kg higher than that of a male of identical build and predicted % body fat was over 11 percentage points higher, but age effects were smaller for females. Considerable racial differences in predicted body fat were found for males, but such differences were less marked for females. The implications of this finding for interpreting recent research on the effect of obesity on health, society, and economic factors are considered. 相似文献

In this paper, a variable repetitive group sampling plans based on one-sided process capability indices is proposed to deal with lot sentencing for one-sided specifications. The parameters of the proposed plans are tabulated for some combinations of acceptance quality levels with commonly used producer's risk and consumer's risk. The efficiency of the proposed plan is compared with the Pearn and Wu [Critical acceptance values and sample sizes of a variables sampling plan for very low fraction of defectives. Omega – Int J Manag Sci. 2006;34(1):90–101] plan in terms of sample size and the power curve. One example is given to illustrate the proposed methodology. 相似文献

We derive explicit formulas for Sobol's sensitivity indices (SSIs) under the generalized linear models (GLMs) with independent or multivariate normal inputs. We argue that the main-effect SSIs provide a powerful tool for variable selection under GLMs with identity links under polynomial regressions. We also show via examples that the SSI-based variable selection results are similar to the ones obtained by the random forest algorithm but without the computational burden of data permutation. Finally, applying our results to the problem of gene network discovery, we identify through the SSI analysis of a public microarray dataset several novel higher-order gene–gene interactions missed out by the more standard inference methods. The relevant functions for SSI analysis derived here under GLMs with identity, log, and logit links are implemented and made available in the R package Sobol sensitivity. 相似文献

Five sampling schemes (SS) for price index construction – one cut-off sampling technique and four probability-proportional-to-size (pps) methods – are evaluated by comparing their performance on a homescan market research data set across 21 months for each of the 13 classification of individual consumption by purpose (COICOP) food groups. Classifications are derived for each of the food groups and the population index value is used as a reference to derive performance error measures, such as root mean squared error, bias and standard deviation for each food type. Repeated samples are taken for each of the pps schemes and the resulting performance error measures analysed using regression of three of the pps schemes to assess the overall effect of SS and COICOP group whilst controlling for sample size, month and population index value. Cut-off sampling appears to perform less well than pps methods and multistage pps seems to have no advantage over its single-stage counterpart. The jackknife resampling technique is also explored as a means of estimating the standard error of the index and compared with the actual results from repeated sampling. 相似文献
