Human resource practitioners play a crucial role in promoting equitable treatment of persons with disabilities, and practitioner's decisions should be guided by solid evidence‐based research. We offer a systematic review of the empirical research on the treatment of persons with disabilities in organizations, using Stone and Colella's seminal theoretical model of the factors influencing the treatment of persons with disabilities in work organizations, to ask: What does the available research reveal about workplace treatment of persons with disabilities, and what remains understudied? Our review of 88 empirical studies from management, rehabilitation, psychology, and sociology research highlights seven gaps and limitations in extant research: (a) implicit definitions of workplace treatment; (b) neglect of national context variation; (c) missing differentiation between disability populations; (d) overreliance on available data sets; (e) predominance of single‐source, cross‐sectional data; (f) neglect of individual differences and identities in the presence of disability; and (g) lack of specificity on underlying stigma processes. To support the development of more inclusive workplaces, we recommend increased research collaborations between human resource researchers and practitioners on the study of specific disabilities and contexts, and efforts to define and expand notions of treatment to capture more nuanced outcomes. 相似文献

Using new survey data from rural Kenya, this paper assesses the moderating effect of women’s empowerment on the relationship between agricultural technology adoption and women’s dietary diversity. We use a multiple treatment endogenous switching regression framework to control for potential endogeneity of women’s empowerment and technology adoption. We find that women’s empowerment has a positive and significant effect on the women’s dietary diversity score regardless of technology adoption status. We further show that women’s empowerment enhances the positive effects of technology adoption on women’s dietary diversity. Although technology adoption has a positive impact on women’s dietary diversity regardless of empowerment status, its effect is stronger for households with empowered vs. disempowered women. Study results suggest that individual and household welfare could be enhanced to a greater degree through interventions that promote women’s empowerment and technology adoption simultaneously rather than separately. 相似文献

多输入多输出-正交频分复用(MIMO-OFDM)无线通信系统中接收信号从空间、时间、频率的维度形成多因素的阵列信号,传统的矢量或者矩阵代数的建模方法在处理多因素信号问题上显得不足,无法利用多因素间的关系,而张量分析在解决多维阵列信号处理的问题上具有优势。针对MIMO无线通信系统,结合OFDM技术,研究了张量信号的建模及分解方法,并充分利用张量信号的分解唯一性提高无线接收信号的检测能力。提出了基于CP(CANDECOMP/PARAFAC)张量分解方法对未知信道状态(CSI)的MIMO-OFDM系统进行接收端的张量信号建模和盲检测,并通过仿真分析验证了模型的可行性。仿真结果表明,在接收天线数目大于发送天线数目且各径信道独立情况下,基于CP分解的接收信号盲检测算法在误码率为10-4时,随着接收天线数目增加,信噪比可获得约5 dB的增益。 相似文献

This editorial addresses one of the greatest challenges of our time—racial inequality. Logistics and supply chain management (SCM) factor prominently in people’s everyday experiences, as consumers of products and logistics services as well as through participation in logistics and supply chain workforces. These everyday experiences can be quite disparate depending on one’s race. As academics, we have a responsibility to peel back the layers of how these issues of race and diversity impact and interact with supply chain phenomena. This editorial is intended to bolster conversation around these issues. We identify compelling themes that merit consideration and, perhaps, deeper investigation, including race as an individual difference variable in our research, race in SCM talent and leadership, and race and racism in SCM execution. We also call for more research that addresses racial inclusion and equal access in other aspects of SCM in light of its far-reaching influence in the realms of business and society. The time has come to address these pervasive issues affecting organizations and individuals. We also introduce the articles appearing in the current issue of the journal. 相似文献

ABSTRACTEast African Community’s (EAC) corporations are required to follow a regional treaty of mainstreaming gender equality. This article discusses challenges encountered by corporate boards of the EAC’s corporations when adding women. Agency and resource dependence theories led the study, while a review of the literature was the methodology. We discuss the benefits of diverse boards and challenges faced when developing this diversity. We show how power distance, masculinity, and certainty avoidance prevent women from corporate boards. Furthermore, we discuss how social orientation and business environment impact women’s participation. The article discusses various strategies to be considered for increasing diversity. 相似文献

Over the last two decades, extensive literature has examined the socioeconomic and environmental impacts of China's Sloping Land Conversion Program (SLCP), a program that was launched in late 1990s to mitigate the environmental effects of agricultural production and reduce rural poverty. However, little empirical evidence exists with regard to the impact of SLCP on rural households' sensitivity to nature-induced changes and environmental challenges. In this study, household-level data covering the period 1995–2010 from five Chinese provinces were used to examine the effect of SLCP on farmers' sensitivity to climate change. The empirical results show that participation in SLCP significantly reduced farmers' sensitivity to climate change by reducing their dependency on land and natural resources for income, and by diversifying their livelihood options. Spatially, the results reveal that the effect of SLCP on farmers' sensitivity vary across regions. Specifically, SLCP was found to have a ‘rate effect’ on farmers in the Northern regions and a ‘level effect’ on farmers in the Southern regions. Likewise, we found that the effect of SLCP differs considerably across income groups, with the effect on low- and middle-income groups being most significant. The results indicate that subsidy is the main pathway through which SLCP reduces farmers' sensitivity to climate change. In contrast, we found inclusive evidence about the indirect effect of SLCP farmers' sensitivity through the promotion of non-agricultural employment. These results carry major implications with regard to the effectiveness of ecological conservation programs and their mitigation potential through building farmers' resilience in China and ecologically fragile environments. 相似文献

Managing agricultural floodplains to meet present and future human requirements without jeopardizing biodiversity conservation is a challenge for land use planners and ecologists. This paper aims to disentangle the relationships between ecosystem services and biodiversity in multifunctional landscapes, such as floodplain agroecosystems, by disaggregating their values across land use types. We measured eight ecosystem services (gas regulation, soil formation, nutrient regulation, habitat provision, food provision, raw materials production, education, and recreation) and six plant diversity indexes (richness, abundance, and true diversity for both plant species and growth forms) in seven land use types identified in the floodplain of the River Piedra (Spain). We observed that all land use types provided services to some extent, but each one was better at providing certain services. Natural or semi-natural habitats provided more services and hosted greater diversity than cultivated land use types. In addition, five diversity indexes were strongly correlated to at least three ecosystem services each one. Habitat provision and education were the ecosystem services positively correlating to most diversity indexes, whereas food provision was negatively correlated to all diversity indexes. Moreover, analyzing the interactions between ecosystem services and biodiversity across land use types, we observed that land use type was the controlling factor regarding the sign and significance of the interaction. The results of this study suggest that, in floodplains agroecosystems, a mosaic landscape of different land use types helps support ecosystem services and contributes to maintaining biodiversity while using local resources. Such land use policies might manage agricultural floodplains at the landscape scale while still being able to accommodate specific measures for each land use type. Moreover, riparian forests should be preserved and restored across the floodplain as they are hot spots for biodiversity and ecosystem services provision. 相似文献

While the impact of organizational diversity on employee work outcomes has received significant research attention, there is a dearth of literature in hospitality settings, particularly in Eastern cultures. Integrating the Social Identity Theory and diversity literature, this study, using data collected from 22 hotels in Taiwan, examined the relationship of perceived organizational diversity with Job Performance (JP), Organizational Citizenship Behaviors (OCB) and Turnover Intention. The results indicated that the level of diversity perceived by hotel employees, significantly influenced employee JP and OCB. Ethnicity status also moderated the relationship between the perception of diversity levels and employee turnover intention. Specifically, a negative relationship between perceived diversity and turnover intention was observed among indigenous employees while a positive relationship was observed among non-indigenous employees. 相似文献
